Abstract

A squeezable, insulated drink bottle includes a flexible, semi-rigid, plastic beverage container that fits inside of and in spaced relationship to a flexible, semi-rigid plastic housing. An inwardly oriented flange around a top opening of the housing locks into a groove under a cover shoulder of the beverage container. Recesses in the housing facilitate gripping of drink bottle.

Claims

1. A thermally insulated drink bottle, comprising in combination:

(a) an inner container having an openable cover disposed at one end, said inner container being composed of semi-rigid collapsible plastic;

(b) a liquid delivery tube supported by said cover to deliver liquid from said inner container;

(c) an outer container of larger diameter than said inner container, said outer container having a top opening into which said inner container slideably fits and being composed of semi-rigid collapsible plastic; and

(d) an interconnection for engaging said inner container in fixed relationship to said outer container to maintain a space between said inner and said outer containers, said interconnection including an annular depression disposed about said inner container and an annular element extending radially inwardly from said outer container for engaging said annular depression.

2. The thermally insulated drink bottle set forth in claim 1 wherein said outer container is of transparent material.

3. The thermally insulated drink bottle set forth in claim 2 including indicia imprinted on an outer surface of said inner container.

4. The thermally insulated drink bottle set forth in claim 1 wherein said annular element is disposed at the perimeter of the opening of said outer container.

5. The thermally insulated drink bottle set forth in claim 3 including means for aligning said outer container with said inner container to prevent coaxial rotation of said inner container relative to said outer container and thereby maintain a fixed relationship between the indicia on said inner container with any indicia on said outer container.

6. The thermally insulated drink bottle set forth in claim 1 wherein said annular depression comprises a groove disposed in said inner container and wherein said annular element comprises an inwardly oriented lip disposed at the opening of said outer container and including a ramp disposed adjacent said groove on a side of said groove opposite from said cover, whereby when said inner container is forced into said outer container through the opening, said lip encounters said ramp, slides over it, and snaps into said groove.

7. An insulated squeezable drink bottle, comprising in combination:

(a) an inner container having an openable top cover, said inner container being composed of plastic;

(b) a liquid delivery tube supported by said cover to deliver liquid from said inner container;

(c) an outer container of larger diameter than said inner container, said outer container having a top opening into which said inner container slideably fits, said outer container being composed of plastic;

(d) an interconnection for engaging said inner container in fixed relationship to said outer container to maintain a constant insulative air gap between said inner and said outer containers; and

(e) a plurality of recesses in said outer container to ease gripping said drink bottle and extending to said inner container to maintain the spacing of the insulative air gap.

8. The insulated squeezable drink bottle set forth in claim 7 including means for aligning said outer container with said inner container to prevent coaxial rotation of said inner container relative to said outer container and thereby maintain a fixed relationship between the indicia on said outer container and the indicia on said inner container.

9. The insulated squeezable drink bottle set forth in claim 7 wherein said interconnection includes a groove in an upper cylindrical shoulder portion of said inner container and an inwardly oriented flange bounding the top opening of said outer container, a lower portion of said groove being bounded by a sloped upper portion of a cylindrical wall of said inner container, whereby when said inner container is forced into said outer container through the top opening, said flange encounters said sloped surface, slides over it, and snaps into said groove.

10. The insulated squeezable drink bottle set forth in claim 7 wherein said outer container is of transparent material.

11. The insulated squeezable drink bottle set forth in claim 10 including indicia imprinted on an outer surface of said inner container.

12. The insulated squeezable drink bottle set forth in claim 11 including indicia imprinted on an outer surface of said outer container.
