DETAILED DESCRIPTION OF THE INVENTION

(24) The following disclosure provides fluid carrying containers and valve assemblies therefor that have a tube which is moveable between an extended position wherein the tube extends from the container for pouring fluid, and a retracted position wherein the tube is substantially within the container. The extendable tube is biased toward the extended position, for example by a spring or the like, and may be held in the retracted position by a cap or other releasable retaining mechanism. One or more fluid flow apertures may be provided near the inner end thereof, and flow control means may be provided to allow the user to adjust the rate of liquid dispensed from the container by varying the extent to which the flow control aperture(s) are uncovered.

(25) The following describes example embodiments wherein the flow control means comprise a second tube within the container that is moveable relative to the extendable tube when the extendable tube is in the extended position, and a trigger is provided to facilitate movement of the second tube in a longitudinal direction with respect to the extendable tube. Other configurations of flow control means are possible in other embodiments, such as for example by rotating the second tube, providing a structure within the container other than a tube which is moveable relative to the extendable tube, or providing means for the user to move the extendable tube relative to a stationary structure within the container that is positioned to block a varying area of the flow control apertures(s) depending on the position of the extendable tube. Also, the example embodiments discussed below are configured for carrying gas or other hydrocarbon fuel, and include certain features that are desirable for such containers, but it is to be understood that other embodiments may have different configurations, and need not be for carrying fuel in all embodiments.

(26) FIGS. 1 and 2 depict an example container 110 that comprises a wall 112, two handles 114 and a valve assembly 118. The wall 112 has an internal surface and an external surface. The wall 112 has top, side and bottom portions and the internal surface defines a hollow chamber 122. The wall 112 can be any shape or dimension for receiving liquids, for example hydrocarbon-based fuels, within the hollow chamber 122. The wall 112 is made from a variety of polymers that can be shaped, for example by injection molding and blow molding techniques. Preferably, the polymers do not degrade in the presence of volatile liquids, such as hydrocarbon-based fuels. For example, nylon and polyethylene are suitable polymers.

(27) In the example illustrated in FIGS. 1 and 2, the wall 112 defines a fill port 116 that provides fluid communication between the hollow chamber 122 and outside the container 110. The fill port 116 comprises sidewalls that are formed by extensions of the external surface of the wall 112. Alternatively, the fill port 116 may comprise a hole in the side wall and an annular flange that is secured about the hole. The flange extends away from the external surface of the wall 112 to provide side walls of the fill port 116. The sidewalls provide a surface for connecting a removable fill port cap 124. The fill port cap 124 connects with the fill port 116 to close the fill port 116. For example, the fill port cap 124 can sealably connect by friction fit, snap fit, a threaded connection with an internal or external surface of the fill port 116 sidewalls. Optionally, the fill port cap 124 includes a tether 126 that tethers the fill port cap 124 to a portion of the container 110. In other embodiments, the container may not have a fill port, and could be filled through the aperture 120 described below, for example by removing the valve assembly 118.

(28) The wall 112 defines an aperture 120 that extends through the wall 112 to provide fluid communication between the hollow chamber 122 and outside of the container 110. The aperture 120 may comprise sidewalls that are formed by extensions of the wall 112. The sidewalls may provide a surface for connecting a removable aperture cap 125. Alternatively, the aperture cap 125 may engage the sides of an annular secondary cap attached to the aperture 120, as described below. The aperture cap 125 engages the sidewalls of the aperture 120 (or a secondary cap) to close the aperture 120. For example, the aperture cap 125 can connect by friction fit, snap fit, a threaded connection with an internal or external surface of the aperture 120 sidewalls, and may optionally provide a water- or air-tight seal about the aperture 120. Optionally, the aperture cap 125 includes a tether 127 that tethers the aperture cap 125 to a portion of the container 110.

(29) The handles 114 are formed from portions of the wall 112. Optionally, the one or more handles are hollow with an internal reservoir that communicates with the hollow chamber 122. As a further option of the container 110, one, or more than one, handles 114 are provided.

(30) The valve assembly 118 is housed within the hollow chamber 122. In the illustrated example, the valve assembly 118 comprises an extendable tube 128, a flow rate adjuster or a supporting structure in the form of a second tube 130, and a biasing member 132 in the form of a compression spring. Other embodiments may have a structure for supporting the extendable tube 128 different from the second tube 130, such as, for example an end wall positioned in the interior of the container 110 and held in place by one or more posts (not shown) or the like coupled to the wall 112, such that the biasing member can bear against the end wall. The supporting structure may also guide the movement of the extendable tube 128. Alternatively, movement of the extendable tube may be guided by features built into the wall 112, such as for example a thicker section of the wall 112 adjacent to the aperture 120. The biasing member 132 may also have other configurations. For example, one or more extension springs could be coupled between the extendable tube and the wall 112. The extendable tube 128 has a first end 134 and a second end 136. The first end 134 of the extendable tube 128 is open to permit fluid to be dispensed therefrom. The second end 136 of the extendable tube 128 may be closed or partially open, and may have one or more flow control apertures therein as described below.

(31) The second tube 130 has a first end 138 and an opposite end wall 140. The first end 138 is open and configured to selectively contact the wall 112 around the perimeter of the aperture 120. The end wall 140 is spaced from the first end 138 to allow the extendable tube 128 to be positioned within the second tube 130. The second tube 130 comprises a closed sidewall that extends between the first end 138 and the end wall 140. Alternatively or in addition to the second tube 130, the supporting structure may comprise one or more support arms that extend from the first end 138, or from the internal surface of the wall 112, to support the end wall 140 at a fixed position within the hollow chamber 122.

(32) The extendable tube 128 is moveable between a retracted position and an extended position, as shown in FIGS. 1 and 2 respectively. When in the retracted position both ends of the extendable tube 128 are preferably within the hollow chamber 122, although it is to be understood that in some embodiments a small portion of the first end 134 of the extendable tube 128 may protrude slightly from the aperture 120. In the extended position, the first end 134 of the extendable tube 128 extends through the aperture 120 to outside of the container 110. In the extended position, at least a portion of the extendable tube 128 remains within the hollow chamber 122.

(33) The biasing member 132 biases the extendable tube 128 toward the extended position. In the illustrated example, the biasing member 132 is a coiled spring that is positioned between the second end 136 of the extendable tube 128 and the end wall 140.

(34) When the extendable tube 128 is in the extended position, flow control means may be operated to place the extendable tube 128 in fluid communication with the hollow chamber 122. When the container 110 is tilted to pour liquid, the extended extendable tube 128 directs a flow of liquid from the hollow chamber 122.

(35) In the illustrated example, the aperture cap 125 can be connected to the aperture 120 (or to a secondary cap attached to the aperture 120) to hold the extendable tube 128 in the retracted position against the force exerted by the biasing member 132. This holds the extendable tube 128 in the retracted position within the hollow chamber 122 of the container 110. When the aperture cap 125 is removed, the biasing member 132 moves the extendable tube 128 toward the extended position. In some embodiments, the biasing member 132 may impart only enough force to move the extendable tube 128 part of the way to the extended position, and the user may pull the extendable tube 128 the rest of the way out. Such embodiments advantageously require less force to be applied by the user when returning the extendable tube 128 into the retracted position. In other embodiments, the biasing member 132 may impart enough force to move the extendable tube all of the way into the extended position. While in the extended position, the container 110 can be tilted to pour liquid from the hollow chamber 122 out the first end 134 of the extendable tube 128. Directing a flow of liquid through the extendable tube 128 may be referred to as dispensing.

(36) In other embodiments, different structures can be used to hold the extendable tube 128 in the retracted position against the force of the biasing member 132. For example, a latch (not shown) or the like may be provided on an inner edge of the aperture 120 and may be moved to selectively engage a corresponding feature such as a notch near the first end 134 of the extendable tube 128 to hold the extendable tube 128 in the retracted position.

(37) FIGS. 3, 4, and 5 depict another example of a valve assembly 218 for use with the container 110. FIGS. 3, 4 and 5 depict only a portion of the container 110, in different orientation than the example shown in FIGS. 1 and 2. FIGS. 3, 4 and 5 also do not depict the aperture cap 125, the fill port cap 124, or the biasing member 132.

(38) The valve assembly 218 can control the rate at which fluids are dispensed out of the container 110. The valve assembly 218 may be similar to the valve assembly 118 described above. For example, the valve assembly 218 is housed within the hollow chamber 122 and it comprises an extendable tube 228 and a second tube 230. The extendable tube 228 has a first end 234 and a second end 236. The extendable tube 228 can move between a retracted position and an extended position. A biasing member (not shown) biases the extendable tube 228 into the extended position. In the retracted position, at least a substantial portion of the extendable tube is contained within the hollow chamber 122. For example, in some embodiments both the first and second ends 234, 236 of the extendable tube 228 are positioned within the hollow chamber 122 in the retracted position (see FIG. 3). In the extended position, at least part of the extendable tube 228 extends through the aperture 120 to outside of the container 110 (see FIG. 4). For example, the first end 234 extends outside of the container 110 and the second end 236 may remain inside the container 110.

(39) The extendable tube 228 includes a fluid flow aperture 200. The fluid flow aperture 200 is positioned near the second end 236 of the extendable tube 228. The fluid flow aperture 200 allows liquid from the hollow chamber 122 to enter internal space of the extendable tube 228. In the illustrated example, liquid that enters the flow control aperture 200 passes through an internal space of the second tube 230, such that the position of the second tube can be adjusted to control the flow rate of liquid being dispensed. Optionally, there can be two or more fluid flow apertures 200, and the location and shape of the fluid flow aperture(s) 200 may vary depending on the structure used to support the extendable tube 228 and the mechanism used to control the flow rate, if any, as described further below.

(40) The second tube 230 has a first end 238 and an opposite end wall 239. The first end 238 is configured to selectively abut to the internal surface of the wall 112 and positioned about the aperture 120. The second tube 230 can move between a closed position and an open position. When the second tube 230 is in the closed position, the first end 238 abuts the internal surface of the wall 112 and there is no fluid communication between the hollow chamber 122 and the internal space of the second tube 230 (see FIGS. 3 and 4). When in the open position, the first end 238 is distanced from the internal surface of the wall 112 and there is fluid communication between the hollow chamber 122 and the internal space of the second tube 230 (see FIG. 5). When the second tube 230 is in the open position fluid may flow from the hollow chamber 122, into the second tube 230, through the fluid flow aperture 200 and into the extendable tube 228.

(41) In one option of the container 110, the valve assembly 218 further comprises a seal 202 that is positioned between the first end 238 of the second tube 230 and the wall 112 around the aperture 120, or other features extending from the wall 112 around the aperture. The seal 202 can be an annular seal that is fixed on the inner surface of the wall 112 (or features extending from the wall 112) around the aperture 120, proximal to the first end 238 of the second tube 230. When the second tube 230 is in the closed position, the seal 202 contacts the first end 238 of the second tube 230 to prevent liquid from entering the second tube 230.

(42) When in the open position, the first end 238 of the second tube 230 is distanced from the wall 112 and a fluid pathway opens between the hollow chamber 122 and the internal space of the second tube 230. Fluid that enters the internal space of the second tube 230 can flow through the fluid flow aperture 200 and into the internal space of the extendable tube 228. The distance between the first end 238 of the second tube 230 and the wall 112 can be varied to change the dimensions of the fluid flow path, which in turn may control the rate at which liquid is dispensed from the container 110 through the extendable tube 228.

(43) In other embodiments, different structures may be provided to selectively open the fluid flow path when the extendable tube 228 is in the extended position, and/or control the flow rate. For example, in some embodiments the extendable tube 228 may be rotated to align the fluid flow aperture(s) 200 with one or more corresponding apertures in the second tube 230 or other supporting structure.

(44) In the illustrated example, a trigger assembly 204 is provided for actuating the valve assembly 218 between the open and closed positions. For example, the trigger assembly 204 comprises a trigger shaft 206 with one end that is coupled to the second tube 230 and the other end of the trigger shaft 206 is connected to a trigger handle 208. The trigger shaft 206 extends from the second tube 230, through the hollow chamber 122, and passes through a trigger shaft aperture 210 in the wall 112. The trigger handle 208 is positioned outside of the container 110. The trigger handle 208 is located near the handle 114 of the container 110 in the illustrated example, but this is not necessary in all embodiments.

(45) In other embodiments, other mechanisms may be provided to actuate the valve assembly 218, depending on the structures provided for opening the fluid flow path when the extendable tube 228 is in the extended position, and/or control the flow rate. For example, a dial may be provided at a convenient location on the exterior of the container 110 and coupled to the extendable tube 228 (either directly or by one or more gears or the like) for effecting rotational movement of the extendable tube 228.

(46) Optionally, the container 110 further comprises a sealing arrangement 212 that prevents the communication of fluids through the trigger shaft aperture 210. FIGS. 3 to 6 and 8 depict one example of the sealing arrangement 212 that comprises a sealing boot 213. One end of the sealing boot 213 is sealingly fit about the trigger shaft 206. The other end of the sealing boot 213 is sealed to the internal surface of the wall 112, around the trigger shaft aperture 210. Optionally, the sealing boot 213 can be clamped between a bushing 216 and the wall 112 by a threaded post 218 that extends through the trigger shaft aperture 210 (see FIG. 4). A nut 219 is threaded onto the threaded post 218 to clamp a washer 221 against the wall 112. Alternatively, the sealing arrangement 212 can comprise various other seals that prevent the communication of fluids through the trigger shaft aperture 210. In one embodiment, in order to accommodate the trigger assembly 204 and the sealing arrangement 212, a portion of the wall 112 proximate to the trigger shaft aperture 210 is more rigid than other portions of the wall 112.

(47) Actuating the trigger assembly 204 moves the valve assembly 218 between the open and closed positions. For example, pulling on the trigger handle 208 will cause the second tube 230 to move to the open position and pushing the trigger handle 208 will cause the second tube 230 to move to the closed position, or vice versa. As another example of the trigger assembly 204, the trigger assembly 204 further comprises a gear assembly (not shown) and the trigger handle 208 comprises a rotatable wheel. The gear assembly translates rotation of the rotatable wheel into linear movement of the trigger shaft 206. Alternatively, the rotatable wheel may be configured such that rotation of the rotatable wheel causes rotation of the trigger shaft 206, which in turn moves the valve assembly 218 between the open and closed positions (for example by rotating the second tube 230 to align one or more apertures therein with the flow control aperture(s) 200 in the extendable tube 228).

(48) In one option of the trigger assembly 204, an operator can operate the trigger assembly 204 to regulate the rate at which fluids flow through the valve assembly 218 and out of the container 110. For example, pulling the trigger handle 208 the entire distance that is allowed within the physical dimensions of the container 110 will provide a maximum flow rate of fuel through the valve assembly 218. In contrast, by pulling the trigger handle less than the entire distance will provide a slower flow rate of fuel through the valve assembly 218. Likewise, in embodiments with a rotatable wheel or dial, the amount of rotation may be varied to control the flow rate.

(49) Fluctuations in ambient temperatures may cause the walls 112 to distort and change shape, which may cause the trigger assembly 204 to move from a position that is aligned along the same plane as the first and second tubes 228, 230, to a position that is not aligned. Preferably, at least a portion of the trigger shaft 206 remains on the same plane as the first and second tubes 228, 230. In one example of the trigger assembly 204, the trigger shaft 206 comprises a deformable feature 220. The deformable feature 220 allows one or more sections of the trigger shaft 206 to deviate from the plane it shares with the first and second tubes 228, 230, while maintaining the coupling relationship with the second tube 230. In one example, the deformable feature 220 is a flat, twist feature that is positioned between the valve assembly 218 and the sealing assembly 212 (as shown in FIG. 3). If the trigger shaft 206 deviates from the same plane as the first and second tubes 228, 230, for example because one or more portions of the wall 112 deform, the flat, twist feature allows the trigger assembly 204 to maintain the operational relationship with the valve assembly 218. Alternatively, the deformable feature 220 may be a coil (not shown) or series of restrictions (not shown) that impart a greater flexibility in the trigger shaft 206 without impairing the ability of the trigger assembly 204 to actuate the valve assembly 218 between the open and closed positions.

(50) Optionally, the trigger assembly 204 may further comprise a biasing feature 222 that biases the valve assembly 218 to the closed position. For example, the biasing feature 222 can be a compression spring that is positioned about the trigger shaft 206. One end of the compression spring abuts the sealing assembly 212 or the internal surface of the wall 112, and the other end of the compression spring abuts a shoulder 207 on the trigger shaft 206.

(51) In use, when the operator pulls the trigger handle 208, the trigger shaft 206 moves the valve assembly 218 to the open position, which compresses the biasing feature 222. When the operator releases the trigger handle 208, the biasing feature 222 moves the trigger shaft 206, by acting on the shoulder 207, to move the valve assembly 218 back to the closed position.

(52) In a further option of the container 110, air can flow into the hollow chamber 122 at the same time as fluid is dispensed therefrom. An airflow regulator or an airflow system regulates the flow of air into and out of the container 110. In the context of this disclosure, the term “air” refers to atmospheric air and a mix of atmospheric air and any other gases that are contained within the hollow chamber 122.

(53) In one option of the airflow system, the extendable tube 228 comprises an internal air channel 240 that is defined by a separation wall 241, as shown in FIG. 6. The separation wall 241 extends from the second end 236 towards first end 234. The separation wall 241 separates the inward flow of air within the air channel 240 from the flow of liquid that is within the extendable tube 228. The air channel 240 may, for example, extend parallel to the internal surface of the extendable tube 228, and may terminate at an airflow aperture (not shown) at the second end 236 of the extendable tube 228. The separation wall 241 may extend all the way to the first end 234 of the extendable tube 228 in some embodiments, or may stop short of the first end 234 in some embodiments.

(54) The air within the air channel 240 flows from the extendable tube 228 into the second tube 230, and out of the second tube 230 through an air escape port 242. Optionally, an air extension tube 244 can be connected to the air escape port 242 to direct the flow of incoming air to a desired portion of the hollow chamber 122. For example, the air extension tube 244 may direct the incoming air to an upper portion of the hollow chamber 122 that is distanced away from the aperture 120. Alternatively, the air extension tube 244 may direct incoming air into any other suitable location.

(55) In another example of the airflow system, the flow of air into, and out of, the hollow chamber 122 may alternatively, or additionally, be regulated by a bidirectional valve assembly 250. The bidirectional valve assembly 250 can be configured to maintain the pressure within the hollow chamber 122 at no more than a predetermined level. The predetermined pressure level may be a value determined by regulated standards for fuel containers. For example, the Canadian Standards Association mandates that a pressure of 20 p.s.i. be maintained in a fuel container at a temperature or 70 C for 4 hours. The bidirectional valve assembly 250 provides an air outlet that allows the operator to manually equilibrate the pressure between the hollow chamber 122 and outside the container 110. The bidirectional valve assembly 250 also provides an air inlet that allows air to enter the hollow container 110 when liquids are dispensed from the container 110. Dispensing liquids from the container creates a vacuum, for example 0.1 p.s.i., within the hollow chamber 122. This vacuum is sufficient to open the bidirectional valve assembly 250 and permit the flow of air into the hollow chamber 122. The bidirectional valve 250 can be positioned at various positions on the wall 112. Preferably, the bidirectional valve 250 is housed within the fill port cap 124, 224.

(56) FIG. 7 depicts one example of the bidirectional valve assembly 250 that comprises a valve body 252, a base plate 254, a plunger 256, a gasket 258, a spring 260, and a top cap 262.

(57) The valve body 252 has an open bottom portion, an open top portion, and a sidewall. The sidewall converges towards the open top to form a shoulder and a neck region of the valve body 252. The sidewalls of the valve body 252 are connected to the fill port 116 by a threaded connection. Alternatively, the valve body 252 can be connected to the fill port 116 by plastics welding, chemical bonding adhesives, snap fit, press fit or combinations thereof. The neck region of the valve body 252 includes venting slots 266 that provide fluid communication for air to pass between the valve body 252 and outside the bidirectional valve assembly 250.

(58) The base plate 254 is fixed in the open bottom of the valve body 252. The base plate 254 comprises one or more venting apertures 264 (shown in stippled lines) to allow air to communicate from the hollow chamber 122 to inside the valve body 252.

(59) The plunger 256 is housed within the valve body 252. The plunger comprises an extended portion and a body portion. The extended portion extends through the neck of the valve body 252 and past the upper edge of the valve body 252. The body portion remains below the shoulder of the valve body 252.

(60) The gasket 258 is positioned on the body portion to form a seal against the shoulder of the valve body 252. For example, the gasket 258 can be an O-ring seal.

(61) The spring 260 is positioned between the base plate 254 and the body portion of the plunger 256. The spring 260 pushes the plunger 256 upwards to form a seal between the gasket 258 and the shoulder of the valve body 252.

(62) The top cap 262 is positioned over the neck region of the valve body 252 and the top cap is in close proximity to the top of the extended portion of the plunger 256. Optionally, the top cap 262 is tethered to a portion of the fill port 116 or the external surface of the wall 112.

(63) In use, the operator can press down on the top cap 262 to contact the top cap 262 with the plunger 256. This contact pushes the plunger 256 towards the base plate 254 and breaks the seal between the gasket 258 and the shoulder of the valve body 252. If the pressure of the air within the hollow chamber 122 is greater than the ambient pressure, air will flow from the hollow chamber 122 through the one or more venting apertures 264, past the body portion of the plunger 256 and out the venting slots 266.

(64) When liquid is dispensed from the hollow chamber 122, the vacuum that is created is strong enough to overcome the spring 260 and ambient air is drawn between the top cap 262 and the neck region of the valve body 252 through the venting slots 266 and venting apertures 264, into the hollow chamber 122.

(65) In the illustrated examples, when the extendable tube 128, 228 is in the retracted position the valve assembly 118, 218 is protected from physical damage because it is contained within the geometric footprint of the container 110. In the context of this application, the phrase “contained within the geometric footprint of the container 110” refers to a configuration where a particular structure does not extend beyond a peripheral section of the wall 112, including the handles 114. This configuration allows the wall 112 or the handles 114 to decrease the incidence of accidental damage to the valve assembly 118, 218. Optionally, the portion of the trigger shaft 206 and the trigger handle 208 that are located outside of the hollow chamber 122, referred to as the exterior portions 270 of the trigger assembly 204, may also be positioned within the geometric footprint of the container 110. For example, the exterior portions 270 can be positioned between one of the handles 114 and the external surface of the wall 112. While the inventors have contemplated various configurations a preferred configuration has the exterior portions 270 positioned between the external surface of the wall 112 and the handle 114 that is located opposite to the aperture 120.

(66) The valve assembly 118, 218 can be oriented at various angles relative to the bottom portion of the wall 112 (compare FIGS. 1 and 8a). In some embodiments, the valve assemblies 118, 218 are oriented substantially parallel with the bottom portion of the wall 112 (as shown in FIG. 8a). In a preferred option of the container 110, the valve assembly 118, 218 is in the substantially parallel position and the valve assembly 118, 218 is positioned above a nominal volume level of the container 110. The nominal volume level of the container 110 represents the maximum volume of liquid that the container 110 is designed to hold. According to fuel container regulations, the nominal volume level of the container 110 is indicated on the external surface of the wall 112. In this preferred position, the valve assembly 118, 218 is not submersed in the liquid hydrocarbon based fuel when the container 110 is standing upright and filled to the nominal volume level.

(67) FIGS. 8a and 8b depict another option of the container 110 that comprises a handle 214 made separately from the wall 112. The handle 214 is more rigid than the wall 112. For example, the handle 214 comprises a plurality of reinforcing ribs 280 that contribute to the rigidity of the handle 214. The reinforcing ribs 280 may extend from one, or a combination, of the handle's 214 top surface, bottom surface, and side surfaces. The reinforcing ribs 280 may extend the entire length of the handle 214, or not. The handle 214 can be made from the same polymeric materials as the wall 112. Alternatively, the handle 214 is made not with reinforcing ribs but with a greater amount of polymeric materials so that the handle 214 is thicker than the wall 112. As a further alternative, the handle 214 is made from materials that are more rigid than the polymeric materials of the wall 112. The handle 214 is connected to the external surface of the wall 112 by various methods including, but not limited to: plastics welding, chemical bonding, use of one or more adhesives, use of connectors (such as rivets, bolts, pins) or combinations thereof.

(68) The handle 214 can further comprise a D-shaped support 282 that defines a second trigger shaft aperture 284. The D-shaped support 282 is positioned adjacent the external surface of the wall 112. The second trigger shaft aperture 284 is positioned to align with the trigger shaft aperture 210 and to receive a portion of the trigger shaft 206 therethrough. As a further option, the cross-sectional shape of the trigger shaft aperture 210, and the second trigger shaft aperture 284, matches the cross-sectional shape of the portion of the trigger shaft 206 that articulates through the trigger shaft aperture 210 and the second trigger shaft aperture 284. This cross-sectional shape matching can be configured to prevent rotation of the trigger shaft 206 about its longitudinal axis so that the trigger handle 208 remains within the geometric footprint of the container 110.

(69) In another option of the container 110, the trigger assembly 204 further comprises a trigger guide assembly 290 that maintains the alignment of the trigger shaft 206 along a preferred path of travel (FIG. 9). For example, the trigger guide assembly 290 can restrict the movement of the trigger assembly 204 within the preferred path of travel that is in the same plane as the valve assembly 218. The trigger guide assembly 290 may also be configured to prevent the trigger shaft 204 from rotating about its longitudinal axis.

(70) For example, the trigger guide assembly 290 may comprise a handle portion 292 and a matching trigger portion 294. The handle portion 292 is positioned on an interior surface of the handle 114, 214. For example, the handle portion 292 is positioned on either, or both, of a top portion and a bottom portion of the interior surface of the handle 114, 214. The trigger portion 294 is connected to, or an integral part of, the trigger handle 208. The trigger portion 294 mates with the handle portion 292 to restrict the movement of the trigger handle 208 along the preferred path of travel.

(71) FIG. 9 depicts one example of the trigger guide assembly 290 where the handle portion 292 is a ridge that extends away from the interior surface of the handle 114, 214 and the trigger portion 294 is a groove, for example a U-shaped groove with two lateral extensions. The U-shaped trigger portion 294 mates with the ridge of the handle portion 292 and any movement of the trigger shaft 206 and the trigger handle 208 is restricted to actuating, towards and away from the valve assembly 118, 218 along handle portion 292.

(72) Another option of the container 110 provides one or more locks to prevent an unintentional discharge of the contents of the container 110. For example, an aperture cap 225 may comprise a first cap 300 and a second cap 302 (see FIG. 10). The first cap 300 comprises a series of threads, one or more ratchet teeth 306, a receiving aperture 308 (shown in stippled lines in FIG. 10) and a releasable boss 310. The first cap 300 is connectable to the container 110 by threading with matching threads that are positioned about the aperture 120, for example, on the external surface of the wall 112. While threading the first cap 300 on to the wall 112, the ratchet teeth 306 move in a first direction past a boss 312 that is positioned adjacent the aperture 112. For example, the boss 312 may be fixed to the wall 112 or the boss 312 may be fixed to a portion of the handle 114, 214 (see alternative configurations in FIG. 1 and FIG. 8a). The boss 312 prevents the ratchet teeth 306 from moving in a direction opposite to the first direction. Together the ratchet teeth 306 and the boss 312 act as a lock 301 to maintain the connection between the first cap 300 and the container 110.

(73) The second cap 302 is releasably housed within the receiving aperture 308. The second cap 302 comprises threads that mate with matching threads on an inner surface of the receiving aperture 308. The second cap 302 comprises one or more ratchet teeth 314 that move in a first direction past the releasable boss 310 to lock the second cap 302 within the first cap 300. The releasable boss 310 can be deformed to release the one or more ratchet teeth 314 (for example, see Arrow Y in FIG. 10). Releasing the one or more ratchet teeth 314 allows the second cap 302 to be rotated in the opposite direction to the first direction and released from the receiving aperture 304. Together the ratchet teeth 314 and the releasable boss 310 act as a releasable lock 318. Optionally, for an operator to deform the releasable boss 310 requires a level of dexterity and/or finger strength that prevents an unintentional release of the releasable lock 318 and removing the second cap 302 from the first cap 300. For example, the releasable lock 318 can act as a child safety lock.

(74) As an option of the first cap 300, the receiving aperture 308 has a sufficient diameter to allow the extendable tube 128, 228 to pass therethrough with, or without, an annular seal to prevent the leak of any fluids between the receiving aperture 308 and the external surface of the extendable tube 128, 228. In other embodiments, caps with different locking structures may be provided.

(75) As a further option of the container 110, the fill port cap 124, 224 comprises one or more ratchet teeth 320 (see FIG. 11). The fill port cap 124, 224 can be connected to the fill port 116 by matched threads, snap fit, press fit, friction fit, or a combination thereof. When the operator connects the fill port cap 124, 224 to the fill port 116, the one or more ratchet teeth 320 can move in one direction past a second releasable boss 322 that is positioned adjacent the fill port 116 on the external surface of the wall 112. The second releasable boss 322 can be deformed to release the one or more ratchet teeth 320, which allows the fill port cap 124, 224 to be removed from the fill port 116. Together the one or more ratchet teeth 320 and the releasable boss 322 act as a releasable lock 324. Optionally, for an operator to deform the releasable boss 322 requires a level of dexterity and/or finger strength that prevents an unintentional release of the releasable lock 324 and removing the fill port cap 124, 224. For example, the releasable lock 324 can act as a child safety lock.

(76) As a further option of the container 110, the trigger assembly 204 further comprises a trigger lock 326 that prevents the operator from actuating the trigger assembly 204. FIG. 9 depicts one example of the trigger lock 326 that comprises a blocking arm 328 and a spring 330 (depicted in stippled lines). The blocking arm 328 is pivotally connected to a portion of the handle 114, 214 (note that only handle 214 is depicted in FIG. 9). In the example illustrated in FIG. 9, the blocking arm 328 is connected by a screw or the like through the middle portion thereof, but in other embodiments the blocking arm may be connected by a screw or the like at or near one of the ends thereof. The blocking arm 328 can pivot between a blocking position and an open position (shown by the arrows in FIG. 9). The spring 330 is positioned about the pivot point of the blocking arm 328 with a first end 332 fixed to the blocking arm 328 and a second end 334 that is fixed to the handle 114, 214. In the blocking position, the blocking arm 328 is adjacent the trigger handle 208 and prevents the operator from actuating the trigger handle 208 to open the valve assembly 118, 218. In the open position, the blocking arm 328 is moved away from the trigger handle 208, which allows the operator to actuate the trigger handle 208. Moving the blocking arm 328 to the open position compresses the spring 330 and brings the first and second ends 332, 334 of the spring 330 closer together. Releasing the blocking arm 328, while in the open position, allows the spring 330 to move the first and second ends 332, 334 away from each other, which moves the blocking arm 328 back into the blocking position. The spring 330 may be omitted in some embodiments, and the blocking arm 328 may be moved manually.

(77) In another option of the container 110, the handle 114, 214 can be pivotally connected at both ends to the external surface of the wall 112, for example by a releasable hinge (not shown), to allow the handle 114, 214 to be pivoted away from a central, vertical plane of the container 110 to allow filling of the container 110 through the fill port 116.

(78) FIG. 8b depicts another option of the container 110 with the fill port 116 positioned away from a central, vertical plane of the container 110 and away from the handle 214. In this configuration, the handle 214 can be positioned along the central line of the container 110 to facilitate an even distribution of the weight of the container 110 while positioning the fill port 116 in an easily accessible location of the container 110.

(79) In another option of the valve assembly 218, the seal 202 can be fixed on the internal surface of the second tube 230. When the second tube 230 is in the closed position, the seal 202 is between the fluid flow aperture 200 and the hollow chamber 122. When the second tube 230 moves to the open position, the seal 202 will move past the fluid flow aperture 200 and the fluid pathway between the hollow chamber 122 and the internal spaces of the first and second tubes 228, 230 will open.

(80) FIGS. 12 to 16C depict other embodiments of a valved fluid container that includes a hollow vessel 10 having a spout aperture 10a formed in the front thereof and a first or pouring handle 12 oppositely disposed on the back of vessel 10. Pouring handle 12 has a corresponding first handle cavity 12a sized to accept the fingers 8 of the operator's hand when grasping pouring handle 12. Handle cavity 12a is defined in part by handle 12 and by oppositely disposed handle side wall 10b. Handle side wall 10b also forms a side wall of vessel 10. A shaft aperture 10c is formed in handle side wall 10b. Spout aperture 10a, shaft aperture 10c, and handle 12 all lie substantially in a common plane which bisects vessel 10 into mirror image halves.

(81) Valve 14 is rigidly mounted in spout aperture 10a so as to also lie substantially in the common plane. Valve 14 is actuated by valve shaft 16 which is journalled through shaft aperture 10c and mounted at its hollow end 16a to valve outer sleeve 24 of valve 14, and at its opposite trigger handle end 16b to trigger handle 18.

(82) Valve 14 includes three nested hollow tubes wherein the innermost or extendable tube is spout 20, the main or second tube is valve main body 22, and the third or outer tube is valve outer sleeve 24. Each of the three tubes; namely, spout 20, valve main body 22, and valve outer sleeve 24, each have opposite downstream and upstream ends, 20a, 20b, and 22a, 22b, and 24a, 24b respectively.

(83) Spout 20 is telescopically nested within valve main body 22 for telescopic motion in direction B relative thereto. Valve outer sleeve 24 is telescopically mounted on valve main body 22 so as to provide a second telescopic motion in direction C of valve outer sleeve 24 relative to valve main body 22. Valve main body 22 is rigidly mounted into spout aperture 10a of vessel 10. The telescopic motions of spout 20 and valve outer sleeve 24 in directions B and C respectively are along valve longitudinal axis D which extends centroidally through valve 14 and valve shaft 16, and wherein axis D intersects handle 12 and corresponding handle cavity 12a.

(84) The hollow end 16a of valve shaft 16 is mounted to the upstream end 24b of valve outer sleeve 24 so that translation of valve shaft 16 in direction E, for example by the operator pulling trigger handle 18 away from handle side wall 10b, imparts a corresponding translation of valve outer sleeve 24 in direction C. Thus, valve outer sleeve 24 may be translated between its seal open position of FIG. 14 and its seal closed position of FIG. 13, wherein, respectively, primary and secondary seals 26, 28, shown as O-rings although this is not intended to be limiting as one skilled in the art would know that other forms of seals would also work, to form fluid inhibiting seals between downstream ends 22a and 24a and between upstream ends 22b and 24b.

(85) With valve outer sleeve 24 in its seal closed position, so that seals 26 and 28 are closed, fluid is inhibited from flowing from the interior 10d of vessel 10 through primary aperture 22c in valve main body 22 and corresponding aperture 20c in spout 20, and air is inhibited from flowing through secondary apertures 22d of valve main body 22.

(86) Locking dogs 32 releasably lock valve outer sleeve 24 when in its seal closed position. Advantageously, locking dogs 32 are actuated so as to lock valve outer sleeve 24 in its seal closed position by the retraction of spout 20 into its storage position fully recessed within valve main body 22. In particular, resilient locking dogs 32 are engaged by upstream end 20b of spout 20 when spout 20 is seated within upstream end 22b of valve main body 22.

(87) In one embodiment, when spout 20 is in its storage position such as seen in FIG. 12, the downstream end 20a is substantially flush with a valve retaining cap 34 mounted over spout aperture 10a. Seating of upstream end 20b of spout 20 so as to be nested and mated within upstream end 22b of valve main body 22, resiliently biases locking dogs 32 into correspondingly positioned notches or grooves 24c or other female depressions formed in the upstream end 24b of valve outer sleeve 24.

(88) As spout 20 telescopically extends from valve main body 22, upstream end 20b releases from its biasing engagement against resilient locking dogs 32 thereby disengaging dogs from locking engagement in grooves 24c. Unlocked valve outer sleeve 24 may then be actuated by valve shaft 16 so as to translate valve outer sleeve 24 from its seal closed position into its seal open position.

(89) In one embodiment, which is not intended to be limiting, a spout ejection spring 36, which may as illustrated be a helical coil spring, is mounted in upstream end 22b of valve main body 22 so as to act upon spring plug 30 which may be inserted within the upstream end 20b of spout 20 thereby resiliently biasing spout 20 into its extended position extended from valve main body 22. Thus in order to engage locking dogs 32 so as to lock valve outer sleeve 24 into its seal closed position on valve main body 22, spout 20 is retracted into its storage position against the return biasing force of spout ejection spring 36. In order to store vessel 10 with spout 20 retracted and valve outer sleeve 24 thereby locked, a spout retainer is employed so as to releasably lock spout 20 in its stored position retracted within valve main body 22. In the illustrated embodiment, which is not intended to be limiting, the spout retainer is a spout retaining cap 38 which releasably mounts onto valve retaining cap 34 so as to cover the opening into downstream end 20a of spout 20.

(90) Spring plug 30 may substantially close off the upstream 20b end of spout 20 fluid passage. This function assists in preventing the fluid 40 that is exiting from container 10 through apertures 22c and 20c and into the inner fluid cavity passage of the spout 20 from flowing over the dividing wall and into the separate air channel 42. Thus the exiting fluid may be directed toward the downstream end 20a of spout 20 without divergence. Further the spring plug provides a surface for the resilient spout spring 36 to act against in its function of ejection of the spout 20. The air channel 42 is continuous through and not blocked by the spring plug.

(91) As best seen in FIG. 14, when fluid 40 is stored within vessel 10 so that the fluid level 40a is above valve 14, and in particular above primary aperture 22c on valve main body 22 when vessel 10 is forwardly tilted into its pouring position with axis D downwardly forwardly inclined and when trigger handle 18 is retracted towards pouring handle 12 so that valve shaft 16 retracts valve outer sleeve 24 into its seal open position, fluid 40 flows through primary aperture 22c on valve main body 22 and through aperture 20c on spout 20, for example along the illustrated fluid path F in direction G so as to decant fluid 40 from spout 20.

(92) An air channel 42 is preferably provided within spout 20, advantageously adjacent the upper side, and in the illustrated embodiment contained within spout 20, so as to allow the ingress of air, for example along airflow path H in direction 1. Thus with axis D forwardly and downwardly inclined so as to pour fluid 40 from spout 20, the volume of fluid exiting vessel may be replaced with a corresponding volume of air flowing through air channel 42 and thence upwardly along valve main body 22 so as to exit via secondary apertures 22d in valve main body 22 into hollow end 16a of valve shaft 16.

(93) Air passage 16c extends along and within valve shaft 16 from hollow end 16a towards trigger handle end 16b. At least one port 16d is formed in valve shaft 16 in airflow communication with air passage 16c so that airflow along airflow path H may escape through port 16d, illustrated in FIG. 14. Port 16d may include an extension such as a flexible tube 16f to extend the air passage 16c upward towards and in some instances above the surface of the contained fluid 40 surface 40a in the passageway within vessel 10 formed between handle cavity 12a of pouring handle 12 and handle cavity 46a of carrying handle 46. Advantageously, port 16d is disposed upwardly.

(94) In one embodiment, a valve spring 48, which may, as illustrated be a helical coil spring, or other resilient biasing means, act on valve shaft 16 so as to resiliently bias valve outer sleeve 24 into its seal closed position. Thus an operator pulling on trigger handle 18 so as to retract handle 18 and valve shaft 16 towards pouring handle 12, retracts valve outer sleeve 24 into its seal open position against the resilient return biasing force of valve spring 48. Valve spring 48, the corresponding portion of valve spring 16, and shaft aperture 10c, may be closed within a resilient sealing boot 50.

(95) The location of the trigger handle provides significant safety, protection from damage if the vessel falls or is dropped, as the pouring handle will help protect the trigger handle from impact and possible damage.

(96) Spout retainer cap 38 may be held in place on valve retaining cap 34 by two tabs 38a on the underside of spout retainer cap 38 that engage within sockets 34a on the valve retaining cap 34. Spring 36 acting on spout 20 holds the cap 38 in place, engaging tabs 38a within sockets 34a. Releasing retaining cap 38, by disengaging tabs 38a from sockets 34a allows spout 20 to freely extend from inside valve main body 22. Retaining cap 38 may be attached to vessel 10 via a tether 38b.

(97) Spout ejection spring 36 acts, at least in part, against spring plug 30. Spout 20 is ejected by spring 36 until tapered upstream 20d end of spout 20 engages with a corresponding tapered surface within spout keeper bushing 54 stopping further extension of spout 20. A pair of opposed flat faces on spout 20 engage in and ride along a corresponding pair of longitudinally extending flat faces in the small bore of spout keeper bushing. Flat faces 20d on spout 20 extend along approximately ¾ of the length of spout 20 from the downstream end 20a of spout 20. Thus when spout 20 is stopped by the tapered faces of spout keeper bushing 54 from further extension from valve main body 22 a short approximately ¼ of the length of spout 20 is retained within downstream end 22b of valve main body 22, at which point primary apertures 20c and 22c are aligned on spout 20 and valve main body 22 respectively communicating through substantially similarly placed apertures in spout keeper bushing 54. The flat faces of spout keeper bushing 54 which are slideably mated in grooves 20d prevent the rotation of the spout 20 relative to valve retaining cap 34. Thus air channel 42 is maintained in an orientation uppermost in spout 20.

(98) The operator may either support vessel 10 by holding the carrying handle 46 or by holding the pouring handle 12 and, as necessary, also supporting the front of vessel 10 under front boss 56. The operator positions the downstream end 20a of the spout 20 in the location where fluid 40 is required before pulling of trigger handle 18.

(99) Valve spring 48 may in one embodiment be mounted between collar 16e on shaft 16 and shaft support bushing 58. Trigger handle 18, when pulled, slides shaft 16 through the bore of support bushing 58. The bore of support bushing 58 may be keyed or otherwise formed to prevent the rotation of shaft 16.

(100) Because it is likely that vessel 10 will distort due to heating and cooling, valve spring 48 is located and mounted such that, even when vessel 10 is distorted, such as when temperatures and vapours expand and contract within the vessel, valve spring 48 maintains a sufficient force upon shaft 16 and thus on valve outer sleeve 24 to maintain the primary and secondary seals 26, 28 closed. In a preferred embodiment such as seen in FIG. 14, air flow along path H passes through a non-flammable screen such as flashback arrestor 60. Arrestor 60 may be included as a safety feature to assist in the prevention of ignition of fumes within vessel 10.

(101) Port 16d in the shaft 16 is preferably disposed upwardly. The placement of port 16d at this greater distance from primary apertures 20c, 22c allows inflow of air behind the mass of out-flowing fluid 40, allowing air into the space behind the out-flowing fluid 40 which prevents formation of a vacuum within vessel 10. The use of air channel 42 as a separate air passage through spout 20 reduces the tendency for the incoming air to force its way back through the outward flow of fluid in spout 20 so as to cause gulping of air and thus interruption of a smooth flow of liquid out of the spout. The addition of an extension air tube 16f onto port 16d allows for an uninterrupted air passage to the back and uppermost portion of the vessel inner cavity 10f. This extension of the air passage H substantially eliminates the occurrence of fluid entering the air passage from the upstream end.

(102) One end of sealing boot 50 is snugly mounted for a friction fit onto shaft 16, adjacent port 16d creating a vapour and fluid seal. Sealing boot 50 is sealed to the handle side wall 10b at bushing 58. The sealing boot 50 is clamped between bushing 58 and handle side wall 10b by threaded post 58a journalled through shaft aperture 10c. Nut 66 threads onto the post 58a and clamps lock washer 66b against handle side wall 10b. Aperture 10c and bushing 58 threaded post 58a are shaped to prevent rotation of post 58a in aperture 10c. For example, aperture 10c may be a D shaped hole.

(103) Valve retaining cap 38 may include a lock to prevent accidental opening of the valve retaining cap. Valve securing boss 56, located on vessel 10 below threaded spout boss 10a, may include a protrusion or arm 56a which lies adjacent a sidewall 34b of valve retaining cap 34. Teeth 34c or other ratcheting means are mounted around sidewall 34b. Teeth 34c engage in a ratcheting cooperation with arm 56a. Thus teeth 34c lock against arm 56a to prevent the unthreading and unwinding of cap 38 from threaded spout boss 10a. Collar 22f is formed as an annular ring around downstream end 22a and is mounted onto the end of threaded spout boss 10a by cap 38 clamping collar 22f onto gasket 34c.

(104) Filler cap 62 is mounted onto vessel 10 by threading cap 62 onto threaded filler boss 10f formed on the top of vessel 10. A securing strap 62a retains filler cap 62 on boss 10f when the cap is unthreaded and removed from the opening into boss 10f.

(105) A securing spring clamp 68 may be provided to inhibit a child tampering with or opening filler cap 62. Spring clamp 68 straddles filler cap 62. The ends 68a of spring clamp 68 may be mounted by hooking ends 68a in apertures 10a in gussets 70 on either side of boss 10f. One end 68a may be unhooked from its corresponding aperture 70a by pushing down in direction J on a lever arm 68b formed so as to be cantilevered from the corresponding side of spring clamp 68. This releases the tension holding end 68a hooked in aperture 70a, so that the end 68a may be released from its aperture 70a.

(106) As will be apparent to those skilled in the art in the light of the foregoing disclosure, many alterations and modifications are possible in the practice of this invention. Accordingly, the scope of the invention is to be construed in accordance with the substance defined by the following claims. The scope of the claims should not be limited by the example embodiments discussed above, but should be given the broadest interpretation consistent with the description as a whole.
