Abstract
Devices comprising a plug positioned within a housing to regulate air within a container, for example, plastic storage containers or bags. One embodiment utilizes a plug that occludes an opening in a housing. The plug is displaced from the opening to inject or evacuate air from a container. An alternative embodiment utilizes a plug having air channels therein which can be sealed once air has been injected into or evacuated from a container. The devices are utilized with hose adaptors connected to vacuum or air hoses having specialized hose tips for coupling with the housing.
Claims15
A device for controlling the amount of air within a container, wherein said device comprises:
- a housing having one or more walls and a base that define an interior and an exterior, having further at least one first opening between the interior and exterior of the device, and at least one second opening between the interior and exterior of the device, wherein the at least one first opening is for receiving a means for injecting or evacuating air;
- a plug contiguous with the housing and comprising at least one sealable air channel there through, wherein the plug occludes the at least one second opening, and wherein the at least one sealable air channel in the plug is contiguous with the second opening and facilitates the movement of air into or out of a container;
- and
- a connecting means on the exterior of the housing for connecting the housing to a container, such that the housing is contiguous with the container, and so that an essentially airtight seal is formed between the housing and an opening in the container;
- wherein, in use, the housing is fixedly positioned so that the at least one second opening is contiguous with an opening in the container, so that the means for injecting or evacuating air can be inserted into the one or more first openings to move air into or out of the container prior to sealing of the at least one air channel;
- and wherein the housing and the plug are each part of a single unit.

A device for controlling the amount of air within a container, wherein said device comprises:
- one or more walls and a base that define an interior and an exterior;
- at least one first opening between the interior and exterior of the device, wherein the at least one first opening is for receiving a means for injecting or evacuating air;
- at least one second opening between the interior and exterior of the device;
- a plug contiguous with the base of the device and comprising at least one sealable air channel there through, wherein the plug occludes the at least one second opening, and wherein the at least one sealable air channel in the plug is contiguous with the second opening and facilitates the movement of air into or out of a container;
- and
- a connecting means on the exterior of the device for connecting the device to a container, such that the device is contiguous with the container, and so that an essentially air-tight seal is formed between the device and an opening in the container;
- wherein, in use, the device is fixedly positioned so that the at least one second opening is contiguous with an opening in the container, so that the means for injecting or evacuating air can be inserted into the one or more first openings to move air into or out of the container prior to sealing of the at least one air channel.

A device for controlling the amount of air within a container, wherein said device comprises:
- a housing having one or more walls and a base that define a hollow interior and an exterior, having further at least one first opening between the interior and exterior of the housing, and at least one second opening between the interior and exterior of the housing, wherein the first opening is for receiving a means for actively injecting or evacuating air;
- a plug positioned at the base of the interior of said housing having at least one sealable air channel there through, and occluding the second opening in the housing, such that the at least one sealable air channel in the plug is contiguous with the second opening in the housing, and facilitates the movement of air into or out of a container;
- and
- a connecting means on the exterior of said housing for connecting said housing to a container, so that an essentially air-tight seal is formed between the housing and an opening in a container for receiving said housing,
- such that, in use, said housing is fixedly positioned so that the at least one second opening in the housing is contiguous with an opening in the wall of a container, so that said means for injecting or evacuating air can be inserted into the one or more first openings in the housing to move air into or out of a container prior to sealing of the at least one air channel;
- and wherein the housing and the plug are each part of a single unit.
