Abstract
Several unique bag closure features are presented, with one embodiment having a bag-neck confining opening provided with inwardly depending appendages peripherally spaced from one another and with blunted ends to protect the bag, but with sharp corners to hold the bag. Another feature of the invention is a perforated plastic bag closure, with the perforations being arranged in a unique pattern to maximize the strength of the closure while reducing its weight. A third feature is a plurality of interconnected, flat, generally rigid closures which are joined in an elongated strip by sets of transversely spaced but outwardly, generally convex webs which space the adjoined, adjacent closures from one another yet leave a smooth web when the closures are separated by breaking the webs.
Claims8
A side opening closure for closing the neck of a flexible bag or the like, comprising:
- a body of flat, generally rigid material having a bag-neck confining aperture and a bag-access opening to said aperture through a side edge of the body, said access opening dividing the body on opposite sides thereof into a pair of jaws;
- said bag-neck confining aperture having a peripheral outline defined by a plurality of peripherally spaced, inwardly extending appendages each having a generally straight, blunted inner edge and a generally straight, blunted side edge defining at least one bag-gripping, pointed corner, and wherein the spaces between and around said appendages define recesses to receive the neck of the bag with the pointed corners of adjacent appendages confronting one another for holding the flexible bag against rotational, endwise movement through the closure.
A side opening closure for closing the neck of a flexible bag or the like, comprising:
- an integral body of flat, generally rigid material having a bag-neck confining aperture and a bag-access opening to said aperture through a side edge of the body,
- said bag-neck confining aperture having a periphery which includes at least one bag-neck locking channel defined by adjacent confronting pointed corners each bounded by and adjoining generally straight blunt edges on either side of the corner, and wherein the distance between the corners along a straight line is shorter than the distance between the corners along the periphery of the bag-neck confining aperture, whereby the bag neck can be gathered within the locking channel and held by the pointed corners but is prevented from perforating by the adjoining blunt edges.
