Abstract

A closure (400) for a hollow pet toy that holds edible materials contains a cut-out relief (410) that extends above a desired shear plane (170). When fully inserted into the large opening (110) of a pet toy (100) the top (420) of the cut-out relief lies above the shear plane, outside the toy. If the pet bites into the closure or wets it with saliva, it will break or disintegrate into sections (510, 610, 620) which are too small or too large to lodge in the large opening of the toy. Thus when the pet bites or wets and breaks the closure, none of the pieces of the closure can lodge in the opening of the toy and prevent the pet from reaching and eating the contents. An alternative embodiment is provided with a cylindrical top (710) which can be eaten by the pet, cannot lodge in the pet toy opening, and which can be printed or embossed with a logo.

Dependent claims

A closure for a hollow container which contains food and which has at least one access opening to such food, where said opening has a predetermined size, comprising:

a body of material having first and second ends and first and second portions adjacent said first and second ends, respectively, said first portion having a cross-section sized to pass through said access opening, said second portion having a cross-section sized so that it will not pass through said access opening,
said body of material having at least one slot extending into said body from said first end providing a means for causing said body to fracture into a plurality of pieces when subject to breaking stress, where each of said pieces is either larger or smaller than said access opening, so that when said closure is inserted in said opening and subject to said breaking stress, none of said pieces will remain lodged in said opening and block access to the inside of said container.
