Substance extruder with a stand

Abstract

The extruder device with a stand is a device designed to increase efficiency of extruding substances from tube-like enclosures. The extruder device is activated by a series of leg/levers that once pushed together, engage a set of geared ratchets which in turn engages stepping gears that in turn engage torque pins which ultimately cause interlocking gear rollers to turn in clockwise and counterclockwise directions allowing the tube-like enclosure to feed through the interlocking gear rollers and thus providing the pressure to extrude the contents of the tube-like enclosures. Because of its simple design, minimal force is required to activate the mechanism thereby extruding the substance of the tube-like enclosure in an efficient and uniform manner. The already spent tube-like enclosure is collected in an enclosed cavity and at the end, disposed of once the unit is opened with relative ease.

DETAILED DESCRIPTION

(6) An embodiment of the substance extruding device is described herein. The device is used to dispense incremental amounts of a substance such as paint, glue, toothpaste, cream, paste, and any viscous substance that is captured in a tube-like enclosure. The tube-like enclosures may be made of a plastic, polymer, paper, aluminum, rubber, metal or metal alloy. The device is designed in such a way as to allow the user to only extrude enough substance for use without spilling or wasting any of it. Furthermore, the device is specially designed to serve both as an extruder as well as a stand for the tube-like enclosure. Additionally, the device incorporates a depositing chamber which captures the expended tube-like material opposite to the dispensing end. Finally, the device easily opens up in order to access the depositing chamber allowing a user to discard the empty tube-like enclosure after all the substance has been extruded.

(7) The device is specially designed to be used in many applications such as for painting of art works, dispensing adhesive material for use in arts and crafts, dispensing toothpaste, creams, and lotions for an average consumer. Additionally, the device can be color coded to allow for immediate identification of the tube-like enclosure that holds the germane substance or, the device can be transparent to allow the user to view the contents of the tube-like enclosure. Furthermore, the device allows the user to store the tube-like enclosure in an upright position with use of the integrated multifunction legs that also act as levers at the time of extruding.

(8) The device is operated with application of minimal force and requires only mechanical components to extrude a substance from the tube-like enclosure. Mechanical components work in unison to advance the tube-like enclosure in the device, thereby, enabling the substance to flow out of the top of the tube-like opening. The device provides an efficient, economic, and environmentally friendly way to extrude the substance of the tube-like enclosure without creating messy application of the substance. This advantage is obtained because the interlocking gear rollers grip the tube-like enclosure and allow the substance to be squeezed out evenly. The device contains device bodies, interlocking gear rollers, fulcrum pins, tension springs, advancing ratchets, advancing pins, stepping gears and legs/levers. These components are illustrated in the drawings in further detail.

(9) An embodiment of the substance extruding device can be color coded to differentiate one device from another, depending on what tube-like enclosure is inserted into the device. Because the tube-like enclosure temporarily remains in the device, it is not necessary to open the device in order to observe the type, brand, or make of the substance contained within the tube-like enclosure captured within the depositing chamber. The color coding of the device indicates to the user the type of substance that will be extruded by that particular device.

(10) An embodiment of the substance extruding device can be made of a transparent material such as plastic, Plexiglas, fiberglass, acrylic, glass or any type of Poly Methyl Methacrylate (PMMA) type acrylic sheet such that a user can differentiate between one device from another depending on what tube-like enclosure is inserted into the device.

(11) An embodiment of the substance extruding device has a thumb locking feature which allows the user to open the device. The opposite end of the device is held together by a swivel hinge that may be used with a pin, leaf, or with a bushing structure. After opening the device, the user has essentially halved the device into its device body and the mechanical components contained therein. This allows the user to access the depositing chamber and discard the empty tube-like enclosure.

(12) One embodiment of the substance extruding device made of a plastic material allows for tube-like enclosures with a width of up to 65 mm to fit through the gear rollers. Furthermore, this embodiment can accommodate tube-like enclosures with a thickness of from 0.2 mm to a 0.4 mm. However, depending on the dimensions of the parts used to construct the substance extruder with stand, other dimensioned tube-like enclosures can be accommodated. The invention here does not limit the size and make of the arts which dictate which tube-like enclosures it will be compatible with. No limitations are intended here.

(13) FIG. 1 illustrates a substance extruder device with a stand (100). The substance extruder device with a stand (100) has two device bodies (102) shown in a partially opened position when they are interlocked together. The device body (102) can be made of a solid substance such as plastic, metal, metal allow, wood, Plexiglass, acrylic, glass, fiberglass or any type of Poly Methyl Methacrylate (PMMA) type acrylic sheet. Each of the device body (102) holds the mechanical components which allow the device to function. The device body (102) also forms the depositing chamber (104) after both device body (102) sections come together to lock into one complete unit, thereby, making up the substance extruder device with a stand (100). Each device body (102) has compartments which allows some of the mechanical components (106) to be inserted into place. Furthermore, each device body (102) has side channels that allow the legs/levers (108) to be inserted and fastened to the device body (102) in conjunction with various other mechanical components (not described here). Finally, each device body (102) has a thumb latch (110) and a latch retention plate (112). The thumb latch (110) and latch retention plate (112) of one device body (102) are integrated in diametrically opposing configuration such that the thumb latch (110) of one device body (102) locks into the latch retention plate (112) of the other device body (102) when each device body (102) section comes together to make up the substance extruder device with a stand (100). Similar relationship is shown with regard to the latch retention plate (112) of one device body (102) and the thumb latch (110) of the other device body (102). The opposite end of each device body (102) is where the swivel hinge (114) holds the substance extruder device with a stand (100) together.

(14) FIG. 2 illustrates the substance extruder device with a stand (100) as it is completely open. As previously discussed, the substance extruder device with a stand (100) has two device bodies (102) shown in a partially opened position. The device body (102) can be made of a solid substance such as plastic, metal, metal allow, wood, Plexiglas, acrylic, glass, fiberglass or any type of Poly Methyl Methacrylate (PMMA) type acrylic sheet. Each of the device body (102) holds the mechanical components which allow the device to function. The device body (102) also forms the depositing chamber (104) after both device body (102) sections come together to lock into one complete unit making up substance extruder device with a stand (100). Each device body (102) has compartments which allows some of the mechanical components (106) to be inserted into place. Furthermore, each device body (102) has side channels that allow the legs/levers (108) to be inserted and fastened to the device body (102) in conjunction with various other mechanical components (not described here). Finally, each device body (102) has a thumb latch (110) and a latch retention plate (112). The thumb latch (110) and latch retention plate (112) of one device body (102) are integrated in diametrically opposing configuration such that the thumb latch (110) of one device body (102) locks into the latch retention plate (112) of the other device body (102) when each device body (102) section come together to make up the substance extruder device with a stand (100). Similar relationship is shown with regard to the latch retention plate (112) of one device body (102) and the thumb latch (110) of the other device body (102). The opposite end of each device body (102) is where the swivel hinge (114) holds the substance extruder device with a stand (100) together.

(15) In an embodiment, the swivel hinge (114) incorporates a male leaf (114a) and a female leaf (114b). The male leaf (114a) and female leaf (114b) of one device body (102) are integrated in diametrically opposing configuration such that the male leaf (114a) of one device body (102) locks into the female leaf (114b) of the other device body (102) when each device body (102) section comes together to make up the substance extruder device with a stand (100). Similar relationship is shown with regard to the female leaf (114b) of one device body (102) and the male leaf (114a) of the other device body (102).

(16) FIG. 3 is a cross sectional view of the substance extruder device with a stand (100) that is partially open. For purposes of brevity, some components are referenced once, even though the same parts are contained within each device body (102). The substance extruder device with a stand (100) depicts the legs/levers (108) with incorporated ridges or textured surface features (108a) which allow the user to grip the legs/levers with two or three fingers of either hand. By holding the legs/levers (108) using for example the thumb and index finger (or index finger and the middle finger), the user can squeeze the opposite facing legs/levers (108) inwards, towards each other, in order to activate the mechanical components and thereby pull the tube-like enclosure (not shown) and extrude the substance.

(17) The mechanical components are shown as: interlocking gear roller (128), fulcrum pin (118), lower tension spring (116), mid tension spring (120), upper tension spring (126), advancing ratchet (122), torque pin (124), stepping gear (130), and the legs/levers (108). The fulcrum pin (118) is used to fasten the sides of the legs/levers (108) unto the device body (102). The fulcrum pin (118) also acts as a swivel point. Under the internal side of the legs/levers (108) and capped in between the inner boundary (102a) of the device body (102) and the key-notch (108b), lies the lower tension spring (116). The lower tension spring (116) is sandwiched in between the inner boundary (102a) and the key-notch (108b) such that the lower tension spring (116) has limited movement. The lower tension spring (116) is activated when the legs/levers (108) are pressed together in an inwardly direction, thereby tensioning the lower tension spring (116). Once tensioned, the lower tension spring (116) will then default to its natural position, which releases the tension on the lower tension spring (116). On the legs/levers (108), there exists a cavity where the mid tension spring (120) is inserted in. The three sided cavity limits and guides the movement of the mid tension spring (120). The advancing ratchet (122) caps the other end of the mid tension spring (120). The advancing ratchet (122) has saw-teeth on the opposite end which meets and interlocks with the stepping gear (130). Once the legs/levers (108) are squeezed in towards one another, the advancing ratchet (122) advances the stepping gear (130) uni-directionally in the clockwise direction. This action provides the force necessary to move the tube-like enclosure (not shown) through the pair of stepping gear (130) components and allows for the substance to be extruded out of the tube-like enclosure. Throughout this process, the mid tension spring (120) provides enough lateral force so that the stepper gear (130) engages or disengages by advancing or staying stationary while the legs/levers (108) go back to their default position. The stepper gear (130) has a square like clearing in the center of the component, which allows the stepper gear (130) to fasten unto the torque pin (124). When the stepper gear (130) is activated as a result of squeezing in the legs/levers (108), the torque pin (124) moves in unison in a clockwise direction. The torque pin (124) fits snug into the interlocking gear roller (128) because the interlocking gear roller (128) also has a square shaped clearing in the center of the component. When the stepper gear (130) moves, the torque pin (124) also moves which results in the interlocking gear roller (128) moving in unison and in the same direction as the stepper gear (130) and the torque pin (124). Each interlocking gear roller (128) has two torque pins (124) inserted from either end met in the middle only with one upper tension spring (126). The upper tension spring (126) provides enough tension so that the interlocking gear roller (128), the torque pin (124) and the stepper gear (130) will stay loaded to further provide a means to completely disassemble this section of the mechanical component for maintenance.

(18) The relationship between the amount of pressure that is applied to the legs/levers (108) and the amount of pressure exerted on the interlocking gear rollers (128) is governed by the following formula:
P.sub.1L.sub.1=P.sub.2L.sub.2
L.sub.1=2.9L.sub.2
P.sub.12.9L.sub.2=P.sub.2L.sub.2
P.sub.12.9=P.sub.2(i)
P=2P.sub.2
P=22.9P.sub.1
P=5.8P.sub.1(ii)
Where P1 is the pressure put on legs/levers gear rollers, L1 is the distance from the legs/levers to the fulcrum, P2 is the pressure outputted on the torque pins and L2 is the distance from the fulcrum pin to the ends of the leg components. Where P2 is equally divided on the four stepping gears which is the reason the power on the shafts increases. Wherein P is the final power output of the combined interlocking gear rollers.

(19) FIG. 4 shows an exploded view of one-half section (101) of the device body with a stand (100). The figure illustrates how the device body (102) houses all the various mechanical components such as: interlocking gear roller (128), fulcrum pin (118), lower tension spring (116), mid tension spring (120), upper tension spring (126), advancing ratchet (122), torque pin (124), stepping gear (130), and the legs/levers (108).

(20) Although the present invention has been described with reference to the preferred embodiment thereof, it is apparent to those skilled in the art that a variety of modifications and changes may be made without departing from the scope of the present invention which is intended to be defined by the appended claims.
