Referring more in detail to the drawings:
This invention contemplates a structure wherein a dispensing valve is arranged to control discharge of flowable materials from a container wherein a valve element is positioned in a dispensing opening and the portion or wall defining said opening serves as one end of the container. The invention further contemplates such a Structure wherein the valve structure includes a body member with a dispensing opening in which a valve element is swingably mounted wherein the body member and valve element are molded of flexible resilient material such as suitable synthetic resin, for example polyvinylchloride, polyethylene, polypropylene and other flexible plastics with a resilient engagement between the peripheral portion of the valve element and the edge of the body member defining said opening providing a seal when the valve element is in closed position. This invention further contemplates a dispensing valve structure wherein the valve element is swingably mounted on a body member for movement to open and close a dispensing opening and the body member removably connected to a container at V the mouth thereof, said body member and valve element preferably being of a material that it may be constructed by molding, as for example, injection molding.
The reference numeralldesignates a container with a valve body member 2 at one end 3. The body member 2 has a dispensing opening 4 with a valve element 5 swingably mountedthereon to open and-close saiddispensing opening. The marginal portionsti adjacent the opening 4 are preferably beveled as at 7 to provide inwardly converging surfaces terminating in an inner edge 8 that defines the opening 4. The valve element 5 is preferably a disc-like member with opposed faces 9 and it and a peripheral portion 11 intermediate said faces adapted to be engaged by the edge 8 to form a seal when the valve element is in closed position. The valve element also has outwardly extending potrions 12 and 13 adjacent said surfaces 9 and .10 to form peripheral lips that extend outwardly beyond the portion 11.
The valve element is connected to the body member by trunnions or hinge members 14 at theperiphery of said valve element whereby 'the valve element may be swung about said trunnions or flexible hinge members 14. It is preferred that the trunnions 14 be at diametrically opposed points and integral with the valve element and body member whereby the valve element swings about an engage the body member adjacent the opening 4.

In the structure illustrated, the tab 15 extends upwardly and outwardly at a side of the val-ve'element in spaced relation to the axis of swinging movement to facilitate Pulling said side upwardly with the lips 12 and 13 and the edge 8 yielding at said side to permit swinging movement of the valve element 5. The swinging movement of the valve element 5 is limited by a projection 16 thereon adapted to In the structure illustrated, the projection 16 is in the form of a depending cylindrical rod-like member with a rounded lower end 17 forming a shoulder 18 arranged whereby when the valve element is swung to open position the rounded portion 17 will engage the edge 8 beyond the shoulder 18 and said shoulder will provide resistance tending to hold the valve element in open position. It is to be understood that the body member 2 may be integral with the container or may be separable therefrom. In the structure illustrated in FIGS. 3 to 5 inclusive, there is a container 19 that has an upstanding wall 29 defining a mouth 21 communicating with the interior of the container. The wall preferably is inclined outwardly to form a groove or recessed periphery as at 22. The closure member includes abody member 23 adapted to be suitably secured on the container at the mouth thereof and, in the structure illustrated, the body member includes a depending wall 24 with an inwardly extending bead-25 adapted to engage under or in the groove defined by the peripheral shape of the wall 29. This particular arrangement allows the body member 23 to be snapped onto the container in resilient tight engagement thereon. Inthe structure illustrated, the body member 23 has a top Wall '26 with a dispensing opening 27 centrally located therein. The marginal portions adjacent said opening have inwardly converging surfaces 28 and 29 that terminate inan inner edge 30 that defines the opening 27. A valve element 31 is positioned in the opening 27, said valve element being a disc-like member having an upper or outer face 32 and a lower or inner face 33. In the illustrated structure, the upper face 32 is crowned and a there are spaced concentric ribs 34 and 35 that are both decorative and'add some strength. It is preferred that the valve element 31 at its periphery 36 have a thickness substantially corresponding to the thickness of the wall 26 of the body 23. The valve element has a mid-portion 3'7' that extends substantially around the periphery or cir- 1 cumferentially and has resilient engagement with the edge 30 of the body member when the valve element is in closed position as illustrated in FIG. 3. From the peripheral portion 37, the periphery is inclined outwardly toward the inner face 33, providing an inclined peripheral face 38 on an angle whereby said face is spaced from the surface 2& of the body member, the face 33 and the inner face 33 cooperating to define a peripheral lip 39 slightly larger than the portion 37. From the peripheral portion 37, theperiphery for one-half of the circumference slopes outwardly, having a face id to form an outwardly extending lip dl that substantially corresponds to the lip 39. While the face all and lip 41 may extend for the entire periphery of the valve element, it is preferred that for slightly less than one-half of the periphery from the portion 37 to the outer face 32 the surface is generally cylindrical as at 42 to reduce the resistance of swinging The valve element also preferably has a tab or suitable member 44 extending outwardly whereby it can be grasped to swing the adjacent side of the valve element upwardly into open position, as illustrated in FIG. 5. The hinge members 43 are preferably adjacent the terminus of the cylindrical portion 42 and the tapered upper portion having the face 40 of said valve element with the tab 44 on a side opposite from the cylindrical portion 42.
The valve element has a depending member 45 with a rounded end 46 forming a shoulder 47 so that when the valve element is swung to open position the rounded portion will engage the edge 39 of the body member and, as the valve element tends to swing back to closed position, the shoulder 47 will engage said edge to retain the valve element in open position until it is forcibly moved to to cause the shoulder 47 to pass the edge 30. As the valve element returns to closed position, the lip 39 on the side having the tab 44 engages the adjacent portion of the edge 30 to resist full closing movement. By pressing on the tab side of the valve element, the lip 3% and edge 3%) yield whereby they can pass to position the valve element in closed position as illustrated in FIG. 3. In this position, the inclined face 46 cooperates with the face 38 to resist movement until pressure is applied in lifting of the tab to cause yielding of the lip 39 and edge 30 sufiiciently for the resistance to be overcome and the valve element moved to open position.
In making a closure structure such as illustrated and described, as by molding from a flexible resilient material, mold members are closed to define a cavity corresponding to the shapes of both the body member 23 and valve element 31. Portions of the mold members also define the spaces between the faces 28, 4t and 42, and the faces 29 and 38, with the inner edges of said mold portions slightly spaced. Those mold portion-s also are arranged to leave a cavity corresponding to the hinge members 43. The material is then injected into the cavities, as for example into the body portion of the cavity, and said material will flow through the cavity and till same but will not pas through the space between the mold portions defining the spaces between the periphery of the valve element and the edge of the body member. The material, however, will flow through the cavity forming the hinge members 43 and thereby fill the cavity for the valve element but that material in the valve clement cavity will not pass through the space at the peripheral edge so that in the product there is engagement of the edge 3% and the peripheral portion 37 but no membrane connecting same, the only connection being the integral hinge members 43.
When it is desired to use the structure, the body member 23 is applied to a container at the mouth thereof with the opening 27 closed by the valve element. With it is desired to dispense some of the contents of the container, the tab 44 is grapsed and lifted, swinging the valve element on the hinge members 43 to a position such as shown in FIG. 5, whereby the contents may be dispensed through the opening 27. When the dispensing is completed, the valve element is swung to closed position, as illustrated in FIGS. 3 and 4. While there is a twisting in the hinge members 43, it is found that such members continue to function for many, many hinging operations and thereby will last for more than the normal use in dispensing of contents from the container.
In the form of the invention illustrated in FIGS. 6 to 8 inclusive, the body member 50 has an opening 51 defined by an edge 52 of substantially the same structure as shown and described relative to the structure shown in FIGS. 3 to 5 inclusive. The valve element 53 is also preferably of the same structure as the valve element 31 as shown in FIGS. 3 to 5 inclusive, and has a peripheral portion 54 adapted to be resiliently engaged by the edge 52. Also the peripheral portion of the valve element has spaced lips 55 and 56 that cooperate in substantially the same manner to resist movement or swinging of the valve member from open to closed position.
In the structure sown in FIGS. 6 to 8 inclusive, the valve element 53 is swingably mounted on a single hinge member 57 that connects the periphery of the valve element 53 with the edge 52 of the body member. The hinge member is substantially the same as one of the hinge members 43 as shown in FIG. 5, but is oppositely disposed relative to a tab 58 on the valve element. The depending projection 59 on the valve element is longer whereby it can engage the edge portion 52 oppositely from the hinge member 57 when the valve element is in open position, as illustrated in FIG. 7. Except for the bodily swinging of the valve element about a single hinge member 57, the operation of the structures shown in FIGS. 6 to 8 inclusive is substantially the same as shown and described relative to the structure in FIGS. 3 to 5 inclusive.
It is to be understood that while we have illustrated and described certain forms of our invention, it is not to be limited to the specific forms or arrangements of parts herein described and shown except insofar as such limitations are included in the claims.
