Abstract

A flexible bag-like liner having a relatively thin wall is adapted to be connected to a wall portion of a receptacle with a liquid passageway provided in association with the wall portion so that liquid may be introduced into the liner and discharged therefrom; the wall portion is adapted to be fitted substantially in sealing relationship with a body portion of the receptacle with discharge means being provided for discharging air from between the liner and the interior walls of the receptacle when fluid under pressure is introduced into the liner to urge the liner against the interior walls of the receptacle. The arrangement is such that when the contents of the liner are partially discharged, a partial vacuum between the exterior of the liner and the interior of the receptacle urges the liner into contact with interior walls of the receptacle.

Claims

1. An improved lined receptacle comprising, in combination:

a rigid, enclosed container having a cylindrical side wall, an attached bottom wall, and a top wall, said top wall having an interior side and an exterior side, said top wall defining two opposed pairs of spaced openings, each of said two opposed pairs including a first gland opening and a second gland opening, said top wall further having first and second skirts extending outwardly from said exterior side and enclosing said first and second gland openings, respectively;

a flexible liner adapted to substantially fill said rigid, enclosed container, said liner comprising first and second opposed, overlying, flexible, rectangularly shaped panels of a film material, said panels sealed at the edges thereof and also sealed across the corners to define a bag enclosure;

first and second gland members sealingly attached to said flexible liner, one of said gland members being attached to the first panel and the other gland member being attached to the second panel, said gland members being separated by a seal along an edge of the panels and in an opposed relationship;

said gland members adapted to engage said two opposed pairs of spaced openings by projecting through the first and second gland openings, respectively, whereby said flexible liner is draped between said two opposed pairs of openings along said interior side of said top wall so as to facilitate filling and draining of said improved receptacle;

each of said first and second gland members including a base sealed to said flexible liner, a spigot extending from said base opposite said flexible liner, and a spout extending from said base opposite said flexible liner;

said spigot of each gland member having a spigot head and a spigot neck so as to snap fit into said first gland opening from said interior side of said top wall and outwardly directed, said first skirt engaging said spigot neck and abutting said spigot head;

said spout of each gland member having a spout head and a spout neck so as to snap fit into said second gland opening from said interior side of said top wall and outwardly directed, said second skirt engaging said spout neck and abutting said spout head, each of said spigots defining means of maintaining a gland member and attached liner in a torque resisting position with the sealed edge of the liner maintained intermediate the gland members and supported between the gland members;

said spout and said base providing a fluid passage between the interior of said flexible liner and said exterior side of said top wall;

seal means for selectively closing said fluid passage; and

release vent means in said top wall for selectively relieving pressure between said rigid, enclosed container and said flexible liner, said vent means centrally located between the pairs of gland openings.

2. An improved receptacle as claimed in claim 1 wherein said spout is internally threaded and said seal means is an externally threaded cap.

3. An improved receptacle as claimed in claim 1 further comprising an O-ring seal about said spout and interposed said base of said gland member and said top wall of said rigid, enclosed container.
