Abstract: A container assembly includes a container having an open top formed in an upper section of the container. The upper section of the container includes an inner peripheral surface, an outer peripheral surface and a flange formed between the inner and the outer peripheral surfaces. The open top is defined by the inner peripheral surface. A cover made by flexible material includes a skirt which includes a first lip, a second lip and a valley formed between the first and second lips. When the cover is mounted to the open top of the container, the flange of the container is engaged with the valley, the first lip is fully in contact with the inner peripheral surface, and the second lip is fully in contact with the outer peripheral surface so as to form an air-tight status. By lifting the second lip, the cover is easily removed from the container.

Abstract: A seal bottle assembly includes a bottle and a cap is removably mounted to the top opening of the bottle to seal the first room. The cap includes a radial hole defined radially therethrough. A switch unit includes a seal part located in the cap, and a control part located outside of the cap. When the control part is pushed toward the seal part, the pressure in the cap and the bottle is the same as that of outside of the bottle assembly so that the cap is removable relative to the bottle. When the control part is pulled away from the seal part and the seal part is moved to seal a communication between the first and second rooms. The pressure in the cap and the bottle is different from that of outside of the bottle assembly so that the cap is not removable relative to the bottle.

Abstract: A storage can includes a can having a restriction portion extending inward from the inner periphery of the can. The restriction portion includes multiple blocks extending from a top thereof and a gap is formed between any two adjacent blocks. A base is removably inserted into the can and has multiple first protrusions. Multiple holes are defined through the inner bottom of the base and located alternatively between the first protrusions. A mounting member is rotatably mounted to the top of the base and has multiple second protrusions which are located alternatively to the first protrusions when the mounting member is mounted to the top of the base. Food is ground between the first and second protrusions by rotating the mounting member, and the ground food drops through the holes and is received in the can. A cap is mounted to the can and has a sealing member.

Abstract: A container includes a container body, a lid member, a first seal valve and a second non-return valve. The lid member is superimposable on the container body to form a storage chamber in the container, and defines therein a first opening and a second opening. The first seal valve is disposed on the lid member, normally seals the first opening of the lid member, and is operable to unseal the first opening of the lid member. The second, non-return valve is disposed in the second opening of the lid member to permit air to actively flow out of the storage chamber of the container body upon reaching a predetermined degree of pressure, and to prevent environmental air from being drawn into the storage chamber.

Abstract: An airtight container includes a cover, a container and two airtight members. The cover is assembled with the container. The cover has an exhaust part and a releasing part defined therein. The two airtight members are mounted in the exhaust part and the releasing part of the cover respectively. Each airtight member having an inlet and an air gap defined at two ends thereof respectively. The air gap communicates with the inlet. The inlet of one airtight member opened toward an inside of the container and the air gap opened toward an outside of the container, the inlet of another airtight member opened toward the outside of the container and the air gap opened toward the inside of the container. Therefore, the container could be sealed or unsealed by pressing the cover to the container or detaching the cover from the container.

Abstract: A cover for a container fits with a sliding air tight fit over the container body. A cover air release valve allows escape of air from the container when removing and installing the cover to create a vacuum seal fit. A handle positioned adjacent to the air release valve enables a user to remove and install the cover with a single hand gripping the handle and pressing the air release valve. Protrusions extending from opposite sides of the container sleeve engage mating L-shaped openings in a bottom edge of the cover to lock the cover in place. Special dual sided cradles engage a top of a vacuum sealed container below each cradle and a bottom of a vacuum sealed container above each cradle so that a series of cradles are used to vertically stack a number of vacuum sealed containers.

Abstract: A sole for footwear includes a sole body having a plurality of protrusions extending from a top surface of the sole body so as to support the wearer's foot. A plurality of apertures are defined through said sole body and located between said protrusions.

Abstract: A container includes a cover engaged on an open top. A channel and an opening are formed in the cover. A knob is slidably engaged in the channel and includes a tube having a pair of shoulders.
