RECYCLABLE COMPOSITE CONTAINER
First Claim
1. A composite container comprising:
- a paperboard hollow body having top and bottom open ends, the body being formed by a sidewall having inner and outer surfaces,a sidewall liner extending peripherally about the inner surface of the body forming a lined body, the sidewall liner being temporarily bonded to the body;
a collar removably connectable to the top open end of the body, the collar comprises a peripheral portion that abuts the top open end of the body and an inner circumferential flange that extends downwardly from the peripheral portion and is sized to fit snugly about the interior wall of the top open end, the inner circumferential flange being bonded to a top portion of the sidewall liner;
a framing element removably connectable to the bottom open end of the body, the framing element having a sidewall that fit snugly within the bottom open end of the lined body and a peripheral rim that receives the bottom open end of the lined body, the sidewall of the framing element being bonded to a bottom portion of the liner, a base connectable to the framing element, the base having a top wall and sidewall, wherein the top wall extends between the sidewall near the top of the side wall, and wherein the top wall and side wall of the base are designed to fit within the sidewall and the top wall of the framing element, and the base further comprising a peripheral lip configured to retain the peripheral rim of the framing element, the peripheral lip having regions of weakened strength so that the base can be removed by engaging the regions of weakened strength, thereby freeing the coupled collar, liner and framing element from the hollow body and allowing a user to rapidly remove and separate the coupled collar, liner and framing element from the hollow body.

Abstract
A composite container having a paperboard hollow body with top and bottom open ends. The body is formed by a sidewall with inner and outer surfaces. The composite container includes a body liner extending peripherally about the inner surface of the body and a base connectable to the bottom open end of the hollow body. The base includes a sidewall sized and shaped to fit snugly within the bottom open end of the body. The sidewall is permanently coupled to a bottom portion of the liner. The composite container also includes a collar connectable to the top open end of the hollow body. The collar has a peripheral portion that abuts the top open end and an inner circumferential flange sized and shaped to fit snugly within the top open end of the body. The inner circumferential flange is permanently coupled to a top portion of the liner. The peripheral portion has regions of weakened strength so that the section of the peripheral portion that abuts the top open end can be removed, thereby allowing a user to rapidly remove the coupled collar, liner and base from the hollow body.

16. A method of manufacturing a composite container comprising:
-
a) wrapping a liner over a cooled shaping mandrel; b) applying a temporary adhesive to one side of a paperboard; c) wrapping the side of the paperboard having the temporary adhesive over the liner on the mandrel forming a lined body; d) cutting the lined body into desired lengths; e) applying a conventional adhesive to end portions of the liner of the lined body; f) adding a collar to a top open end of the lined body, the collar being bonded to the liner and only frictional coupled to the body; g) adding a framing element to a bottom open end of the lined body, the framing element being permanently bonded to the liner and only frictional coupled to the paperboard of the body; and h) connecting a base to the framing element, the base configured to be removable from the framing element. - View Dependent Claims (17, 18, 19)
