The present invention relates to the technical field of pizza boxes, comprising a box body and a top cover. The box body and the top cover have triangular sector structures. The top end of the box body is open, and the edge of the open end extends outward to form a clamping flange; a lower end surface of the top cover is hermetically abutted against an upper end surface of the clamping flange; the side wall of the top cover is hinged with a plurality of claw buckles along a circumferential direction; the claw buckles have clamping plates and are clamped with the lower end surface of the clamping flange; and the bottom of the box body and the edge of the top cover are wrapped with heat insulation layers. The heat insulation pizza box of the present invention has good sealing and heat insulation effects.

The present embodiments describe an insulated drinking vessel with a multifunction lid. In an embodiment, the drinking vessel can be configured to receive a multifunction lid. The multifunction lid may, in one embodiment, include an opening for receiving a drinking straw. In an embodiment, the multifunction lid may additionally include an opening for drinking or sipping directly through the lid. In an embodiment, the lid may include an operable cover for covering at least one of the openings in a first position and for allowing access to the fluid through the opening in a second position. In a further embodiment, the lid may include a plurality of operable covers. A first operable cover may be configured for covering the drinking straw opening in a first position and allowing insertion of a straw in a second position. The lid may also include an operable cover for covering the sipping spout in a first position and allowing drinking directly through the spout in a second position.

A storage container comprising a container base having an upper opening defined by a peripheral top edge of the base; a removable lid with a circumferential seal, wherein the lid sealingly sits across the upper opening of the base; and a clip mounted to the base to rotate between an engaged position whereby the clip engages the lid against removal, and a disengaged position; wherein the clip includes a contact surface that as the clip rotates from the engaged position to the disengaged position, the contact surface is moved to lift the lid.

A sealable container system contains a body and a lid assembly. The body includes an internal volume defined by bottom and side wall(s), bump(s) on the inside surface of the side wall and projecting toward the internal volume, and a lid with outer and inner walls at its bottom side with a channel in-between. A gasket couples to the lid with a wall portion residing within the channel and a lip outside the channel. When the lid assembly is pressed into the body, the lip of the gasket engages the bumps and deforms, and a gap forms between the lip and the side wall, where air in the internal volume exits through the gap. When the lip of the gasket travels past the bumps, the lip fully seats against the inside surface of the side wall, where negative air pressure is imparted to the internal volume of the body.

A hazardous material shipping container comprises a shell having a first threaded portion at a first end thereof, a closed second end opposite the first end, inwardly extending ribs, and outwardly extending flutes, wherein the ribs and flutes are disposed between the first end and the second end. A cushioning material is inside the shell, and a cap has a second threaded portion adapted to mate with the first threaded portion and a recess on a lower surface wherein the recess is adapted to receive an upper portion of a material container.

A container set includes a cover, a base, the cover having a cover sealing member which is made of elastic material and protrudes from a cover peripheral edge of the cover to allow the cover to engage the base, and a first container received between the cover and the base and having a container edge to allow the first container to engage an inner surface of the cover. In addition, the inner surface of the base has a base groove to allow the cover sealing member to engage the base groove when the cover engages the base, wherein the container edge, the cover sealing member and the base groove constitute an interlocking structure. With this interlocking structure, the cover, the base and the container(s) located therebetween can form a tightly engaged container set.

A container system with an interlocking mechanism is disclosed. The containers of the system have interlocking components that securely interconnect the individual containers vertically, so that groupings of containers can be transported easily. The containers can be water tight and air tight. The container can be modular and form infinite combinations of stacked and interlocked groupings.

A beverage cup for containing a beverage includes a beverage ingredient container installed in the beverage cup for placing beverage ingredients, and a cup lid fastened to the mouth of the beverage cup. The beverage ingredient container has an upper cup and a lower cup concavely and downwardly formed for placing the beverage ingredients, and a beverage through hole formed at the bottom of the upper cup. The cup lid includes a cover, a straw protruded from the cover, and a straw cap connected to an edge of cup lid by a strip for covering the straw, so that the straw cap can cover a straw mouth to prevent beverage leakage and keep the straw mouth clean. When drinking, the beverage enters into the beverage ingredient container through the beverage through hole and flows together with the beverage ingredient towards the straw to achieve the effect of drinking the beverage together with the beverage ingredients. Since the beverage cup reduces the use of straws, plastic films, and waste that is uneasy to recycle, this invention will make the environment healthier and cleaner.

An accessory for use with a portable container includes a jacket having a storage member and configured to extend around at least a portion of the sidewall of the container and a connection member connected to the jacket and configured to support the jacket in connection with the container. The connection member includes a connector configured to be connected to a port on the container such that a portion of the connector is received through the port.

A bottle assembly is provided including a bottle having an end portion with a first detent formation, and a collar having a second complementary detent formation. The collar is arranged to snap fit to the end portion by engagement of the detent formations by application of force only in a direction towards the bottle. In addition, a valve assembly for use with a drinking vessel is provided including a base member and a sealing member. The sealing member is movable, dependent on a pressure difference across it, between a sealed position, wherein the sealing member is sealed against the base member, and an unsealed position, wherein the sealing member is unsealed from the base member. One or more channels are formed between the base member and the sealing member and are arranged to allow air to enter the drinking vessel when the sealing member is in the unsealed position.
