Abstract

A new insulated container, includes a hollow bottle being composed of pliable resilient material, and an insulation sleeve disposed over a portion of the outer surface of the bottle and being contracted frictionally thereabout. The sleeve has a mouth portion for receiving the bottle. The sleeve is composed of a pliable resilient material and includes an outer insulation sleeve portion and an inner pliable sleeve portion having a smooth inner surface to facilitate the insertion of the bottle into the sleeve. The method includes forming the two-part sleeve, and then inserting the bottle into the sleeve by first moving them together telescopically until a portion of the bottle disposed within the sleeve. Thereafter, the axially directed bottle-contracting impacts are applied abruptly to the bottle and the sleeve at opposite ends thereof to cause them to move axially relative to one another until the bottle is free to expand outwardly within the sleeve for gripping the bottle frictionally.

Claims

1. An insulated container, comprising:

a hollow member having a sidewall, said hollow member having a large transverse cross sectional area throughout its axial length in its unstressed condition;

an insulation sleeve for helping to inhibit the loss of thermal energy from a liquid stored in said hollow member;

said insulation sleeve having a mouth portion, said mouth portion being slightly smaller in cross sectional area relative to said large cross sectional area of said hollow member in its unstressed condition for receiving said hollow member in a stressed condition;

said insulation sleeve including a soft, outer sleeve portion for insulating said hollow member;

said insulation sleeve including a semi-rigid inner sleeve portion, said inner sleeve portion having a smooth substantially straight cylindrical sidewall portion complementarily-shaped relative to the shape of said sidewall of said hollow member to facilitate the insertion of the hollow member into the insulation sleeve;

said cylindrical sidewall of said inner sleeve portion having a transverse cross section area throughout its axial length that is slightly smaller relative to said large transverse cross sectional area of said hollow member throughout its axial length in its unstressed condition for securing frictionally and confining said hollow member in a stressed condition to cause a tight frictional interengagement between said inner sleeve portion and said member throughout their axial lengths when said member is disposed within said sleeve;

said hollow member being composed of a material sufficiently resilient to contact radially inwardly to permit the hollow member to enter said insulation sleeve through its mouth portion; and

said hollow member being under tension within said insulation sleeve and tending to expand radially outwardly to grip frictionally in substantially an irremovable manner said inner sleeve portion surrounding said hollow member.

2. A container according to claim 1, wherein said sleeve being composed of polyvinylchloride material.

3. A container according to claim 2, wherein said outer sleeve portion is composed of a foam polyvinyl chloride material.

4. A container according to claim 2, wherein said inner sleeve portion is composed of a polyvinyl chloride material.

5. A container according to claim 1, further comprising:

closure means including a cap and a tube extending through an opening therein.

6. An insulated container according to claim 5, wherein said closure means further includes vacuum eliminating means to facilitate the discharge of the contents of said hollow member through said tube when said hollow member is squeezed.

7. A container according to claim 1, further including an annular collar and means for securing said annular collar to a top portion of said hollow member;

said annular collar further being dimensioned and constructed to matingly engage a top portion of said insulation sleeve, said collar having carrying means affixed thereto.

8. A container according to claim 7, wherein said carrying means includes a strap.

9. An insulation container according to claim 7, further comprising:

closure means for sealing said hollow member to substantially prevent the underlying contents within said hollow member from being dispensed therefrom; and

said closure means being dimensioned and constructed to be secured removably to the top portion of said hollow member.

10. An insulated container according to claim 1, wherein said hollow member includes a bottom portion and wherein said insulation sleeve is shaped to conform substantially to the bottom portion of said hollow member.

11. An insulated container according to claim 10, wherein said insulation sleeve is disposed over substantially the entire outer surface of the bottom portion of said hollow member.

12. An insulated container according to claim 1, wherein said hollow member is a container.

13. An insulated container according to claim 12, wherein said container is a bottle.

14. An insulated container according to claim 1, wherein said hollow member is a bottle composed of a pliable resilient material for permitting a user to squeeze it manually so the contents therein can be disposed therefrom.
