A bottle cap includes a vacuum unit, a pressure relief unit and a drinking water pipe unit. After the bottle cap is combined with a bottle, the vacuum unit can vacuum the interior of the bottle to preserve food or drink inside the bottle, and the pressure relief unit may be operated to release the air pressure in the bottle in order to open the bottle cap, or open a flip cover of the drinking water pipe unit to drink the fruit juice or water from the bottle. The bottle cap has the effects of preserving the food or drink in the bottom and facilitating drinking.

A disposable container for solvent contaminated wipes and a method of using the disposable container to prevent solvent contaminated wipes from spontaneously combusting is disclosed. The disposable container may be a flexible bag made of a material having a solvent-resistant, non-permeable layer and optionally other layers. The disposable container has an oxygen-reduction system including an air-tight seal, which may be formed in a variety of ways, and an oxygen-removal mechanism, such as a small pump that is integral to the flexible bag or a pump outlet that can be connected to an external pump.

The present invention includes an inner holder, an outer can, a first check valve and a second check valve. The inner holder includes a storage space. The outer can includes a slidable variable space for the inner holder to slide therein and an air channel for the slidable variable space to communicate with an exterior. The inner holder includes an air hole for the storage space to communicate with the slidable variable space. The first check valve is provided on the air hole and has an airflow direction towards the slidable variable space. The second check valve is provided on the air channel and has an airflow direction towards the exterior. The outer can is slidably moved outwards relative to the inner holder to suck out the air in the storage space and then slidably moved inwards relative to the inner holder to discharge air to the exterior.

A sealing bag which could separate an inside of the sealing bag from the outside includes a bag body, wherein a first zipper, a second zipper, and an exhaust device are disposed on the bag body. The bag body has a storage space and an opening. The first zipper is for closing the opening of the bag body. The second zipper is for dividing the storage space into a first sub-space located between the first zipper and the second zipper and a second sub-space. The exhaust device is disposed between the first zipper and the second zipper for vacuuming air in the first sub-space. Therefore, a force generated by the atmospheric pressure and exerted on the bag body is greater than the force generated by the expansion of remain air in the second sub-space, so that the second zipper is always in a closed status.

A container cover for storage container includes a rotary device, an outer cover member, an inner cover member, a first guide block, second guide block, a pumping piston and a piston seat so arranged that when the rotary device is driven by a user to rotate the first guide block, guide rods of the first guide block are moved along a first continuous wave-shaped track of the second guide block, causing the second guide block and the pumping piston to move alternatively up and to further pump air out of the storage container through an air-pimping hole of the piston seat to create a negative pressure. Further, a first spring member an upper rail seat can be provided to balance the movement of the pumping piston and to stabilize the rotation of the first and second guide blocks. A relief valve rod can be selectively used for giving a visual indication indicative of the presence of a negative pressure in the storage container.

A container intended for vacuum-storage of foods, including a tube for passing air, which is open at the two ends thereof; a cover for closing the container, the cover including means for connecting with the tube of the container, a channel for passing air extending between a first opening defined by the connection means and a second opening, a member for closing a channel, such as a valve, and a mechanism for opening an air passage between the first opening and another opening, such as the second opening.

Provided is an automatic air-extracting sealing box cover, comprising a bottom cover and a top cover that are mutually detachably connected, wherein the bottom cover and the bottom cover are connected to form a device chamber, and an automatic air extracting apparatus is mounted in the device chamber; the automatic air-extracting apparatus comprises a power source, a pressure sensor, an air pump, and a controller; the power source is connected to power source input ends of the pressure sensor, the air pump and the controller; an air extracting opening of the air pump and a probe of the pressure sensor project out of a lower surface of the bottom cover; an output end of the pressure sensor is connected to a collection circuit, and an output end of the collection circuit is connected to an input end of the controller; a control signal output end of the controller is connected an on/off control end of the air pump.

A container cover for storage container includes a rotary device, an outer cover member, an inner cover member, a first guide block, second guide block, a pumping piston and a piston seat so arranged that when the rotary device is driven by a user to rotate the first guide block, guide rods of the first guide block are moved along a first continuous wave-shaped track of the second guide block, causing the second guide block and the pumping piston to move alternatively up and to further pump air out of the storage container through an air-pimping hole of the piston seat to create a negative pressure. Further, a first spring member an upper rail seat can be provided to balance the movement of the pumping piston and to stabilize the rotation of the first and second guide blocks. A relief valve rod can be selectively used for giving a visual indication indicative of the presence of a negative pressure in the storage container.

A cap for closing a container including a cap body for contacting an open end of the container and at least one connector mounted to an exterior of the cap body for coupling the cap body to the container. The at least one connector includes an engaging piece and a lever. An initial movement of the at least one connector causes the engaging piece to contact the container and a further movement of the at least one connector causes the engaging piece to affix the cap body to the container.

The disclosure provides a vacuum storage tank, comprising a vacuum storage tank body. The vacuum storage tank body is provided with a storage cavity and a pressure release channel in communication with the storage cavity. The pressure release channel is provided with a pressure release structure, the pressure release structure includes a pressure release cylinder, and the pressure release cylinder is placed in the pressure release channel. The pressure release cylinder includes a manipulation part and a sealing member for blocking a port of the pressure release channel, and the manipulation part extends from an outer wall of the vacuum storage tank body. A reset retaining structure is arranged between the pressure release cylinder and the vacuum storage tank body to control the pressure release cylinder so that the sealing member keeps blocking the port of the pressure release channel.
