Retaining collar for liner-containing container

摘要

The retaining collar is seated on the upper edge of the outer shell of a container and has the same shape as the upper edge. The collar has a pair of side walls between which the upper edge is accommodated. The upper margin of a liner is also accommodated between the side walls of the collar. The collar is composed of resiliently deformable material such that when the upper edge of the outer shell and the upper margin of the liner are between the side walls of the collar, the side walls resiliently and releasably secure the liner to the outer shell of the container.

主权项

1. A retaining collar for removably securing a liner within an outer shell of a container having an upper opening defined by a rim, said liner having an upper margin which defines a mouth and an interior, said retaining collar having a top wall which is adapted to be seated on said rim and which follows the contours of said rim; a pair of outer and inner side walls which extend down-wardly from said top wall, said side walls being separated from one another by a space which is adapted to receive both said rim and said upper margin, said side walls being composed of resiliently deformable material such that when said rim and said upper margin are within said space, said side walls resiliently contact said upper margin and releasably secure said upper margin to said rim.
