Containers with optional venting
View Patent ↗An optional venting container comprises a base and a lid. The lid is releasably latched to the base. The lid comprises at least one veritable area formed therein. The at least one veritable area is adapted to form a vent only upon a user asserting pressure thereon. The lid is made from a polymeric foam.
1. A ventable container, comprising:
a base including,
a bottom wall, and
a base sidewall extending upwardly from the bottom wall to define a volume of the base, wherein the base further includes a base rim extending from the base sidewall opposite the bottom wall; and
a lid releasably engageable with the base, wherein the lid and the base are movable relative each other between an open position and a closed position, wherein the base rim provides support for the lid in the closed position, the lid including,
a top wall having a flat central region,
a lid sidewall extending downwardly from the top wall at a first angle with respect to the central region of the top wall,
a lid rim extending from the lid sidewall opposite the top wall, and
at least one selectively ventable area located between the central region of the top wall and the lid side wall, the at least one selectively ventable area being movable between a closed condition and an open condition by exertion of an external force imposed upon the at least one selectively ventable area, the at least one selectively ventable area being disposed at a second angle with respect to the central region of the top wall to permit ventilation via the at least one selectively ventable area when a substantially identical ventable container is stacked on the top wall, the second angle being different than the first angle.
2. The ventable container according to claim 1 , wherein the at least one ventable area is defined by at least a first score and a second score spaced apart from the first score.
3. The ventable container according to claim 2 , wherein the first score and the second score together form a general U-shape.
4. The ventable container according to claim 3 , wherein the at least one ventable area includes a hinge, wherein the at least one selectively ventable area is detachable about the hinge.
5. The ventable container according to claim 4 , wherein the hinge is disposed on the at least one ventable area opposite the sidewall.
6. The ventable container according to claim 2 , wherein the first score and the second score define a perforation.
7. The ventable container according to claim 1 , wherein the top wall of the lid is substantially rectangular and the at least one ventable area is disposed proximate a corner of the top wall.
8. The ventable container according to claim 1 , wherein the lid rim projects laterally outward from the lid sidewall and is releasably latched with the base rim.
9. The ventable container according to claim 1 , wherein the lid is coupled to the base along a portion of the base by a hinge.
10. The ventable container of claim 1 , wherein at least one of the base and the lid is made of a polymer foam.
11. The venatable container according to claim 10 , wherein the polymer foam is selected from at least one of alkenyl aromatic polymeric foam, polyolefin foam, polystyrene foam, and polyester foam.
12. The ventable container of claim 1 , wherein the base and the lid are made of the same material.
13. The veritable container of claim 1 , wherein the veritable container has a thickness of from about 30 to about 150 mils.
14. A plurality of substantially identical ventable containers, each ventable container comprising:
a base including,
a bottom wall, and
a base sidewall extending upwardly from the bottom wall to define a volume of the base, wherein the base further includes a base rim extending from the base sidewall opposite the bottom wall; and
a lid releasably engageable with the base, wherein the lid and the base are movable relative each other between an open position and a closed position, wherein the base rim provides support for the lid in the closed position, the lid including,
a top wall having a flat central region,
a lid sidewall extending downwardly from the top wall at a first angle with respect to the central region of the top wall,
a lid rim extending from the lid sidewall opposite the top wall, and
at least one selectively ventable area located between the central region of the top wall and the lid side wall, the at least one selectively ventable area being movable between a closed condition and an open condition by exertion of an external force imposed upon the at least one selectively ventable area, the at least one selectively ventable area being disposed at a second angle with respect to the central region of the top wall to permit ventilation via the at least one selectively veritable area when one of the plurality of ventable containers and another one of the plurality of ventable container are stacked one on another, the second angle being different than the first angle.
15. The plurality of substantially identical ventable containers according to claim 14 , wherein the at least one ventable area is defined by at least a first score and a second score spaced apart from the first score.
16. The plurality of substantially identical ventable containers according to claim 15 , wherein the first score and the second score together form a general U-shape.
17. The plurality of substantially identical ventable containers according to claim 16 , wherein the at least one ventable area includes a hinge, wherein the at least one selectively ventable area is detachable about the hinge.
18. A ventable container, comprising:
a base; and
a lid releasably engageable with the base, wherein the lid and the base are movable relative each other between an open position and a closed position, the lid including,
a top wall having a flat central region,
a lid sidewall extending downwardly from the top wall at a first angle with respect to the central region of the top wall, and
at least one selectively ventable area located between the central region of the top wall and the lid side wall, wherein the at least one selectively ventable area is defined by at least one score, the at least one selectively ventable area being movable between a closed condition and an open condition by exertion of an external force imposed upon the at least one selectively ventable area, the at least one selectively ventable area being disposed at a second angle with respect to the central region of the top wall to permit ventilation via the at least one selectively ventable area when a substantially identical ventable container is stacked on the top wall, the second angle being different than the first angle.
19. The ventable container according to claim 18 , wherein the at least one ventable area includes a surface disposed between the top wall and the lid sidewall, the surface being disposed at the second angle with respect to the central region of the top wall.
20. The ventable container according to claim 1 , wherein the at least one ventable area includes a surface disposed between the top wall and the lid sidewall, the surface being disposed at the second angle with respect to the central region of the top wall.
21. The ventable container according to claim 14 , wherein the at least one veritable area includes a surface disposed between the top wall and the lid sidewall, the surface being disposed at the second angle with respect to the central region of the top wall.
22. The ventable container according to claim 18 , wherein the base includes a bottom wall, and a base sidewall extending upwardly from the bottom wall to define a volume of the base, wherein the base further includes a base rim extending from the base sidewall opposite the bottom wall to provide support for the lid in the closed position.
23. The ventable container according to claim 18 , wherein the at least one score is defined by at least a first score and a second score spaced apart from the first score.
