CONTAINER AND SLIDING CLOSURE THEREFOR Filed Nov. 25, 1950 2*? [Z INVENTORS 1344C Gre /v 4004p @744? Patented Nov. 13, 1951 UNITED... STATES PATENT OFFICE CONTAINER AND SLIDING CLOSURE THEREFOR Q 1 f meets and Adolph Pitar, Brooklyn, N. Y.

Application November 25, 1950. Serial No. 197,606

X 3 Claims. 1-

This invention relates'to containers such as pouches, bags and the like having oppositely disposed wallsproviding a linear mouth opening, and the invention has particular reference to a sliding closure therefor which resiliently maintains the oppositely disposed walls in closed relation and which providesvconvenient means for releasing the walls to permit of the spreading of the same apart for gaining access to the container.

An object of the invention is to provide a container of said character with a sliding closure which is adapted to resiliently maintain the opposite Walls in closed abutting engagement throughout the length thereof for effectively closing the container.

Another object of the invention is to provide a sliding closure having opposite portions which are slidably arranged in longitudinally extending tunnels in the oppositely disposed walls of the container defining the mouth opening and which portions hold the walls of the container in closed relation by the inherent spring tension thereof.

Still another object of the invention is to provide a closure of the indicated character which is slidable in the tunnels of the opposite walls of the container throughout the entire length thereof to afford a wide-opening mouth therefor.

With the foregoing and other objects in view, reference is now made to the following specification and accompanying drawings in which the preferred embodiment of the invention is illus trated.

In the drawings:

Fig. 1 is a view in elevation of a container provided with a sliding closure constructed in accordance with the invention.

Fig. 2 is a longitudinal sectional view taken approximately on line 2-2 of Fig. 1.

Fig. 3 is an enlarged fragmentary sectional view taken approximately on line 3-3 of Fig. 2.

Fig. 4 is an enlarged fragmentary sectional view taken approximately on line 44 of Fig. 3.

Fig. 5 is a vertical sectional view taken approximately on line 5-5 of Fig. 1.

Fig. 6 is a fragmentary cross-sectional view taken approximately on line 6--6 of Fig. 1.

Referring to the drawings by characters of reference, the invention is illustrated in its application to a pouch l0 having oppositely disposed longitudinally extending side walls and 12 which are integrally connected together alon the bottom edge I3 and with the side walls connected together at their ends by stitching l4 and I5. The side walls H and [2 are fashioned 2 of flexible material and as illustrated the same may have a waterproof inner facing 16.

The upper longitudinal edges of the side walls form a linear mouth opening I1 and in order to provide means for securing the said walls in closed relation, the same are folded inwardly along their free upper edges with the inwardly folded portions secured to the body of the walls by lines of stitching l8 and [9 to thereby form longitudinally extending tunnels and 2| at the upper ends of the walls, which tunnels are closed at one side of the pouch by the line of stitching l4 and are open at the opposite ends thereof. A spring closure member 22 consisting of a length of spring material bent upon itself provides oppositely disposed legs 23 and 24 which are slidably arranged in the tunnels 20 and 2| and are of a length to extend from end to end of the tunnels and to protrude through the open ends thereof with the protruding ends connected together by a rebent portion 25.

The rebent portion 25 is of looped formation in order to normally tension the legs into abutting engagement throughout the length thereof whereby the same retain the upper edge portions of the side walls H and I2 in close fitting engagement throughout the length of the tunnels. The leg members 23 and 24 are slidable in the tunnels throughout the length thereof and have their inner ends formed into downwardly directed loops 26 and 21. The rebent portion 25 is located adjacent the open ends of the tunnels when the legs 23 and 24 are engaged therein throughout the length thereof and in order to limit the outward movement of the legs and prevent disengagement of the same from the tunnels, the tunnels are restricted by a line of stitching 28 which extends through the opposite side walls II and I2 and through the inturned portions thereof providing the tunnels. The downwardly directed loops 26 and 21 are adapted to engage against the inwardly curved portions 29 and 30 of the walls H and I2 adjacent the line of stitching 28 for retaining the legs in the tunnels, it will be understood that the cross-sectional area of the tunnels above the inwardly curved portions 29 and 30 of the walls H and I2 is sumcient to slidably receive the legs 23 and 24.

What is claimed is:

1. In a container, oppositely disposed side walls connected together along three edges thereof and unsecured along the upper edges to provide a mouth opening, said walls having inturned upper edge portions secured to the body thereof in spaced relation from the upper edges of said walls to provide tunnels extending longitudinally of said walls and opening through one side of the container, a closure consisting of a length of spring material bent to provide a spring loop and oppositely disposed confronting legs, said legs being of a length to engage in said tunnels from end to end thereof for resiliently maintaining the upper edge portions of said side Walls in closed abutting relation, and said legs being slidable into protruding relation from saidtunnels to permit of the spreading of said side walls apart for opening the container.

2. In a container, oppositely disposed side walls connected together along three edges thereof and unsecured along the upper edges to provide a" mouth opening, said. walls having inturned upper edge portions secured to the body thereof in spaced relation from the upper edges of said walls to provide tunnels extending longitudinally of said walls and openingj-through one side of the container, a closure consisting of- :a length of spring material bent to provide a spring loop and oppositely disposed confronting legs, said legs being of a length to engage in said tunnels from end to end thereof for resiliently maintaining the upper edge portions of said side walls in closed abutting relation, and said legs being slidable into protruding relation from said tunnels to permit of the spreading of said side walls apart for opening the container and having, inner end portions rebent into overlying relation with said legs adapted to engage against the walls of the container adjacent the open ends of said tunnels for retaining the inner ends of the legs in the tunnels.

,.nels fromendto end thereof for resiliently maintaining the upper edge portions of said walls in closed abutting relation, and said legs being slidable into protruding relation from said tunnels to ,,=perm i-t of .the spreading of said side walls ap'artior opening the container and said legs havingtheir inner end portions bent into angular relation and adapted to @engage against the walls of theucontainer adjacent the open ends of the tun-nels for retaining the closure in protruding relation from the tunnels.
