Disclosed is a double-wall vacuum-insulated food container with complementary lid. The body of the container has a base and an upwardly-extending side wall terminating in an upper free edge. The container also has an inner portion and a complementary outer portion with a gap between. The lid sealingly fits onto the upper free edge of the container. The lid includes a central member and a surrounding frame with a sealing ring. The sealing ring serves as an interface between a lower peripheral edge of the frame and the upper free edge of the container. The frame has fastening members which complementary features disposed about the upper free edge of the container. Within the container is a separator having an outer profile substantially complementary with an inner contour of the container, whereby the interior of the container may be selectively divided by a user.

A packaging box is provided, which comprising a box body with a top opening and an openable cover connected at a top of the box body. The box body comprises a bottom wall and a side wall connected to a peripheral edge of the bottom wall, and a top of the side wall forms an arc top edge folding outward. The openable cover further comprises a top wall and a fastening part connected to a peripheral edge of the top wall. A convex rib is formed on the fastening part which matches with the arc top edge. The convex rib blocks at a lower edge of the fastening part. A concave recess is respectively arranged on opposite sides of the side wall. The sealing performance as well as the strength of the packaging box is effectively improved, while the structure of the packaging box is convenient for operation.

The invention described herein relates to a reusable bottle, including a threadless bottle; a cap comprising an outer cap and an inner cap, wherein the inner cap is received in the outer cap and creates a vacuum seal when the cap engages a bottle, wherein the cap engages the bottle using a threadless friction fit. To remove the cap from the bottle, one simply slides the cap off the bottle.

A container, including a jar having an open end and screw threads on its outer surface near the open end thereof, a ring adapted to screw onto the screw threads for securing an adjustable opening lid, wherein many pouring and dispensing options for materials disposed in the container are possible, including the use of an implement to remove contents therein, is described. The jar member may comprise a Mason jar, as an example, and can be resealed between uses and refilled as required.

A device for sealing a vessel, having a stopper for closing the vessel, the stopper including a sealing mechanism for sealing with the vessel; an attachment ring for attaching the stopper to the vessel, the ring has a sleeve provided with a radial flange with a central opening, and first attachment mechanism to be attached to the vessel; a cover having a radial disc and second attachment mechanism; a blocking element having an axial wall and a complementary attachment mechanism engaging in the assembled state with the second attachment mechanism. The axial wall has on one portion of its periphery a tearable tab defined between two grooves forming bridges of thin material, the tab having, on one side, a gripping portion and ending, on the opposite side, with a flared portion such that, once torn, the axial wall opens out along the entire height allowing removal of the blocking element.

A separable container including a top and a base joined by a locking ring, the top and the base attached to the ring through locking tabs adapted to sealingly attach the top to the base through the ring. The base is of a converging shape allowing bases to be nestled within each other when separated from the top for easier transport when empty. When assembled the container typical includes a bladder to hold a liquid to be dispensed and a pressuring means enables the liquid to be dispensed.
