PREFERRED EMBODIMENTS OF THE INVENTION
[0069] In view of the aforementioned figures, and in accordance with the adopted numbering, one may observe therein preferred exemplary embodiments of the invention, which comprise the parts and elements described in detail below. Thus, in the figures, up to five preferred embodiments of a cap object of the present invention are observed.
[0070] As can be seen in said figures, the cap of a liquid container, receptacle or bottle, object of the present application, generally comprises: [0071] a perimeter wall (16, 106, 516) that can be fit to an opening of a liquid container, [0072] a first surface (25, 205, 525) having at least one mouthpiece (24, 204, 524) that rises from said surface (25, 205, 525) and with at least one first orifice (21, 201, 521) for the outlet of liquid from the container, the first surface (25, 205, 525) also having at least one second orifice (22, 202, 522) for the inlet of air into the container, and this second orifice (22, 202, 522) having a one-way valve (23, 203, 523) that allows air to enter the container, but prevents liquid from coming out, and [0073] an air supply system (40, 41, 42, 43, 44) that extends from the perimeter wall (16, 106, 516) to the second orifice (22, 202, 522) to lead air to said second orifice (22, 202, 522) from the perimeter wall (16, 106, 516).
[0074] The present invention shows in FIGS. 1 to 16 thereof various examples of caps comprising two bodies, a first body (20, 200) and a second body (10, 100), whereas FIGS. 17 and 18 show an exemplary embodiment with a single body (500).
[0075] The examples in FIGS. 1 to 16 have a cap where: [0076] The first surface (25, 205) is arranged in a first body (20, 200), [0077] The perimeter wall (16, 206) is arranged in a second body (10, 100) formed by a second surface (11, 101) with a hole (13, 103) to insert the mouthpiece (24, 204) of the first body (200), and [0078] The air supply system (40, 45) is at least one duct (108, 109, 204, 209) located between the first surface (25, 205) of the first body (20, 200) and the second surface (11, 101) of the second body (10, 100), in communication with the outside of the cap through at least one third orifice (14, 104) arranged in the perimeter wall (16, 106) of the second body (10, 100) to allow air (A) to enter said air supply system (40, 45).
[0079] In these FIGS. 1 to 16, up to four embodiments of the invention are shown, in which the air chamber 40, 41, 42, 43 is arranged between the second surface 11 of the second body 10, 100 and the first surface 25, 205 of the first body 20, 200, the air chamber 40, 41, 42, 43, 44 being connected to the outside of the cap, when said cap is coupled to a container 30 through third orifices 14, 104 arranged in the perimeter wall 16, 106 of the first body.
[0080] More particularly, FIGS. 1 and 3 show a first embodiment of a second body 10, which has a second surface 11, substantially flat or smooth, surrounded by a perimeter wall 16 that incorporates means (not shown) for the coupling thereof to the opening of a container or receptacle 30 containing the liquid to be administered through the cap object of the present invention. Said second surface 11 has a hole 13 and preferably a slot 15 close to the hole 113. Likewise, the perimeter wall has at least one third orifice 14, preferably four, arranged separately in said perimeter wall 16. The first body can incorporate a cover or lid 12 that fits over said first body 11, blocking the different orifices 15, 14. Said cover or lid 12 can incorporate internal projections 17 that are inserted at least partially into the different orifices of the cap to block the same. The cover or lid 12 can comprise closing means 18 that are complemented by closing means 19 in the first body 11. In this example, a flange-like projection 18 is shown which is inserted into a recess 19. The material of the second body 10 of the cap is preferably a rigid or semi-rigid plastic in the solid state, preferably polyethylene, and although flexible, it is not elastic in said state.
[0081] A first embodiment of a first body 20 shown in FIGS. 2 and 4 has a mouthpiece 24 that emerges from a first surface 25, substantially flat or smooth, and has a first liquid outlet orifice 21 arranged at the free end of the mouthpiece 24. This first body has a second orifice 22 for the inlet of air, which in this example is in the form of a slot. This second air inlet orifice 22 also has a one-way valve 23 in the bottom portion of the first surface 25, the bottom portion that will face the housing of the container or receptacle 30 once the cap has been coupled to it. In this example, the valve 23 forms part of the second body 20 of the cap 1, as it is made of the same material as said cap and in the same manufacturing process. The material of the first body 20 of the cap is preferably a rigid or semi-rigid plastic in the solid state, preferably polyethylene, and although flexible, it is not elastic in said state. In any case, a first body 20 would also be possible with two or more materials, at least one for the first body 20 and another for the valve, and it can be manufactured in a single injection or two, provided that they allow the manufacture of the first body 20 in such a way that the components form a single body or part.
[0082] The one-way valve 23 consists of, in an exemplary embodiment, a tubular body that forms part of the first body 20 of the cap, with the walls of the first end of said tubular body surrounding the air inlet orifice 22 and the walls of the second end of said body being in contact with each other, closing the duct of the valve 23. The one-way valve could alternatively be made up of a silicone or latex element coupled to the first body 20 and coinciding with the second orifice 22.
[0083] FIG. 5 shows an exemplary embodiment of a cap 1 of the invention with the first body 20 coupled to the second body 10 after inserting the mouthpiece 24 of the first body 20 into the hole 13 of the second surface 11 of the second body 10. The base of the mouthpiece 24 on the first surface of the first body 20 is fitted to the hole 13 of the second surface of the first body 10, thus forming the cap 1. The slot 15 of the second surface 11 of the second body 10 is aligned with the second air intake orifice 22 on the first surface 25 of the first body 20. This slot 15 is optional.
[0084] The second body 11 of the cap 1 has as fixing means for fixing to a container, receptacle or bottle 30, a thread inside the perimeter wall 16 of the second body 10 to be fit to the neck or opening of the container, receptacle or bottle 30 as well as a lid or cover 12 integral with the second body 10 of the cap 1. As mentioned, the lid 12 can incorporate projections therein that adapt to the liquid outlet orifice or orifices 21, as well as projections 17 that adapt to the air inlet orifice or orifices 22. For the projection 17 to be able to adapt to the second air inlet orifice 22, it is necessary for there to be a slot 15 in the first surface 11 so that said projection 17 can be inserted into the slot 22.
[0085] FIG. 6 shows a user drinking from a bottle or container 30 with a cap object of the invention. The cap allows the beverage inside the bottle 30 to be consumed comfortably and without the risk of the liquid coming out the same through the second air inlet orifice 22, since it has a one-way valve. Thus, a consumer will suck through the first liquid outlet orifice 21 of the mouthpiece 24, creating a depression inside the container or bottle 30 that will cause the one-way valve 23 to open and therefore air to enter inside the container or bottle 30. When no depression is created, because there is no suction, the valve 23 closes and remains in this situation.
[0086] FIG. 7 shows a perspective cross-section of an exemplary embodiment of the cap 1 of the invention with the first body 20 coupled to the second body 10. To ensure the operation of the cap 1 as described, it is necessary to ensure that the air A reaches the second air A inlet orifice 22, and therefore the valve 23, arranged in the first body 20 of the cap 1 while that the user is sucking through the first liquid L outlet orifice 21. The natural access of air A to the second air A inlet orifice 22 is the slot 15 arranged in the first body 10, but this slot 15 can be blocked by the user's lips when said user inserts the mouthpiece 24 into his or her mouth to suck the liquid L through the first orifice 21.
[0087] Thus, in the event that this slot 15 is blocked or this slot 15 is not provided in the first body, it is necessary to facilitate the access of air A to the second air A inlet orifice 22, which is achieved given the situation of the third air A inlet orifices 14 inside the cap. These third orifices 14 provide access to an air chamber 40 formed when a duct is created between the second body 10 and the first body 20, specifically, between the second surface 11 of the second body 10, the first surface 25 of the first body 20 and the perimeter wall 16 of the second body. In this way, the cap 1 allows, as already described above, the beverage inside the bottle 30 to be consumed comfortably and without the risk of the liquid coming out of the bottle 30 through the second air inlet orifice 22. When a consumer or user wishes to drink directly from the bottle 30, he or she can either suck or drink from the stream of beverage.
[0088] If the user sucks through the first liquid L outlet orifice 21 through the mouthpiece or spout 23, a depression is created inside the bottle 30 that causes the one-way valve 23 to open, thus allowing air A to enter inside the bottle as said air passes through the third orifices 14, reaches the air chamber 40 and from there reaches the second orifice 22 to, after passing through the valve 23, reach the inside of the bottle 30. The greater the suction, the greater the opening of the valve 23, the greater the air A inlet and, therefore, the greater the liquid L outlet will be. On the contrary, the same thing happens, since when no depression is generated, because there is no suction, the valve 23 closes.
[0089] If the user wishes to drink from a stream of the beverage, i.e., directly from the stream that comes out through the first liquid L outlet orifice 21 of the cap 1, he or she can compress said bottle 30 externally if the bottle 30 allows so, such that the valve 23 is sealed by the compressing action of the liquid L inside the bottle 30 on the same, forcing the liquid 30 to come out through the first liquid L outlet orifice 21, as if the cap 1 only incorporated a single orifice in the surface thereof.
[0090] The operation of the cap object of the invention described above for the exemplary embodiment of FIGS. 1 to 7 is also applicable to the exemplary embodiments of the caps 2, 3, 4, 5 that are described below, as well as in FIGS. 8 to 18.
[0091] Thus, FIGS. 8 and 10 show a second embodiment of a second body 100 of a cap object of the invention. Said second body 100 has on the underside of the second surface 101 thereof a third channel or channels 109 that extend near, or around, the hole 103 and are connected to third orifices 104 arranged in the perimeter wall 106 of the first body 100 through fourth channels 108. If the second body 101 incorporates a slot 105 in the first surface 101 thereof, the third channels 109 will describe the trajectory thereof near the hole 103 from said slot 105. The second body 100 can incorporate a cover or lid 102 that can have projections 107 depending on the orifices to be blocked in the cap. Said third channels 109 and fourth channels 108 preferably have a semicircular cross-section, although they could also be square or triangular, for example.
[0092] FIG. 9 shows a second exemplary embodiment of a first body 200 of a cap. It incorporates a first channel or channels 209 in the top side of the first surface 205 that preferably extend near, or around, the base of the mouthpiece 204 from the second air inlet orifice 202 arranged in the first surface 205 of the first body 200. Said first channels 209 connect to the periphery or perimeter of the first body 200 through second channels 208. Said first channels 209 and second channels 208 preferably have a semicircular cross-section, although it could also be square or triangular, for example.
[0093] The first bodies 20, 200 and second bodies 10, 100 can be combined with each other indistinctly to form different caps. Sometimes it may be necessary to make small modifications for the correct coupling between the two bodies. FIGS. 11 to 16 show cross-sections of four different examples of caps 1, 2, 3, 4 formed by the coupling of the first bodies 20, 200 and second bodies 10, 100.
[0094] FIGS. 11 and 12 show a cap 1 formed by the first exemplary embodiment of the first body 20 (FIGS. 2 and 4) coupled to the first exemplary embodiment of the second body 10 (FIGS. 1 and 3). There is a fit between the perimeter of the mouthpiece 24 and the hole 13 in the second body 10. Specifically, they are two cross-sections of the cap 1 in FIG. 7. In these cross-sections, the air supply system 40 can be seen in the form of a chamber or duct arranged between the first surface 25 of the first body 20 and the second surface 11 of the second body 10 separated from each other by a distance equal to or greater than the height of the third orifices 14. Likewise, it can be seen how said chamber 40 is in communication with the outside through the third orifices 14 arranged in the second body 10 and, in turn, it communicates with the second orifice 22 in the first body 20 and therefore with the one-way valve 23 formed in the first body 20 itself. In this cap 1, the second body 20 has a slot 15 aligned with the second orifice 22, but said slot 15 may not be in said second body or, on the contrary, it may be, but not aligned with the second orifice 22.
[0095] FIGS. 13 and 14 show a cap 2 formed by the second exemplary embodiment of the first body 200 (FIG. 9) and by the second exemplary embodiment of the second body 100 (FIGS. 8 and 10). There is a fit between the perimeter of the mouthpiece 204 and the hole 103 in the second body 10. In said cross-sections, the first channel 209 and second channels 208 of the first body 200 can be seen facing, respectively, the third channel 109 and fourth channels 108 of the second body 100. The attachment of the first channel 209 and third channel 109, as well as the attachment of the second channels 208 and fourth channels 108 form the air supply system 41 of the cap 2, specifically a duct or chamber that communicates the outside of the cap 2 with the second orifice 202 of the first body 200. The second channels 208 and fourth channels 108 communicate with the outside through the third orifices 104 made in the perimeter wall 106 of the second body 100. In this cap 2, the first surface 205 of the first body 200 is in contact with the second surface 101 of the first body 100 over the entire surface thereof except where the channels 208, 209, 108, 109 are located. The supply system 41, formed by the ducts which are in turn formed by the channels 208, 209, 108, 109, lead the air from the third orifices 104 to the second orifice 202 of the first body 200 where the one-way valve 203 formed in the first body 200 itself is located. In this cap 2, the second body 200 has a slot 105 aligned with the second orifice 202, but said slot 105 may not be in said second body or, on the contrary, it may be, but not aligned with the second orifice 202.
[0096] FIG. 15 shows a cap 3 formed by the second exemplary embodiment of the first body 200 (FIG. 9) coupled with the first exemplary embodiment of the second body 10 (FIGS. 1 and 3). In this cap 3, the air supply system 42 of the second orifice 202, and of the one-way valve 203 (not shown), is formed by the first channel 209 and second channels 208 made in the first surface 205 of the first body 200 combined with the second surface 11 of the second body 10, the first surface 205 of the first body 200 being in contact with the entire second surface 11 of the second body 10 except where the channels 209, 208 meet. The cross-section of the channels 209, 208 can vary depending on the needs of the air flow that must circulate through the same. The second channels 208 are aligned with the third orifices 14 of the first body to allow air to enter from outside the cap 3 to the second orifice 202 and valve 203 of the first body 200.
[0097] FIG. 16 shows a cap 4 formed by the first exemplary embodiment of the first body 20 (FIGS. 2 and 4) coupled with the second exemplary embodiment of the second body 100 (FIGS. 8 and 10). In this cap 4, the air supply system 43 of the second orifice 22, and of the one-way valve 23 (not shown), is formed by the third channel 109 and fourth channels 108 made in the second surface 25 of the second body 100 combined with the first surface 25 of the first body 20, the first surface 25 of the first body 20 being in contact with the entire second surface 101 of the second body 100 except where the channels 109, 108 meet. The cross-section of the channels 109, 108 can vary depending on the needs of the air flow that must circulate through the same. The fourth channels 108 are an extension towards the inside of the second body 100 of the third orifices 104 to allow air to enter from outside the cap 4 to the second orifice 22 and valve 23 of the first body 20, since the third channel 109 passes above the second orifice 22 communicating said third channel 109 with said second orifice 22.
[0098] In the cross-sections of FIGS. 11 to 16, the cover or lid 12, 102 integral with the second body 10, 100 has not been shown. Likewise, the cross-sections of the channels have been represented as semicircular, but they could have other cross-sections with a variable depth and width depending on the needs.
[0099] FIGS. 17 and 18 show another exemplary embodiment of a cap 5 which, unlike the previous ones, is formed by a single body 500 with a perimeter wall 516 that fits into an opening of a liquid container and a first surface 525. This surface 525 has a mouthpiece 524 that rises from said surface 525 with a first orifice 521 for the outlet of liquid and also has a second orifice 522 for the inlet of air into the container. This second orifice 522 has a one-way valve 523 that allows air to enter the container, but prevents liquid from coming out. The cap has an air supply system 44 that extends from the perimeter wall 516 to the second orifice 522 to lead air to said second orifice 522 from the perimeter wall 516. Specifically, said air supply system 44 is formed by a first channel 509 that surrounds the mouthpiece 524 and second channels 508 that communicate said first channel 509 with the perimeter wall 516, specifically with openings or orifices 504 made in said wall 516. Said openings or orifices 504 have a larger cross-section than that of the second channels 508 to facilitate the inlet of air into the supply system 44. In this cap 5, when the user inserts the mouthpiece 524 into his or her mouth to drink, his or her lips will probably cover both the first channel 509 and the second air inlet orifice 522, so that the air supply system 44 will be made up of the duct formed by the user's lips and the bottom of the channels 509, 508, which will have sufficient depth to guarantee the circulation of air from the orifices or openings 504 and the second orifice 524 through the second channels 508 and the first channel 509. This cap 5 preferably has second channels 508 in communication with the first channel 509. The cap 5 also shows a cover or lid 512 integral with the body 500 of the cap with internal projections 517 intended to block the first orifice 521 located in the mouthpiece 524, as well as the second orifice 522.
