A cover includes a bistable flap mechanism made of a plastic with at least two material components. The cover can be produced in one piece in a multi-component injection molding technique. At a transitional area between a front wall and an edge portion, the plastic is sufficiently stiff (preferably due to greater material thickness) to ensure that an angle enclosed in the transitional area from the side wall to the edge portion remains constant in both bistable states. Expansion portions provided in the edge portion ensure that the outer circumference of the edge portion can increase/decrease from one bistable state to the other bistable state. A closing system including the cover is also provided.

An insulating container may include an opening, which can be sealed by a closure. The closure may have an upper portion with a handle that has a circular curvature equal to the cylindrical portion of the closure. The closure may also have a lower portion that is joined to the upper portion by an injection molded polymer element. The closure may also be in the form of flip type of closure such that the lid can be selectably opened or closed by the user by rotating a flip closure into either the opened or closed position. The closure may also be a two-part lid having a lower cap that may be configured to be removably-coupled to the container and an upper cap that may be configured to be removably-coupled to the lower cap.

This invention is a tamper evident container having a base and removable lid comprising a pull tab and a lid surface, wherein the base and lid fit together with an interference fit. The pull tab extends toward the center of the lid surface and away from a base portion of the pull tab, the base portion being located at an edge of the lid. The pull tab further comprises a pull tab portion having a first side that is attached to a first tab marker by a first frangible line, and a second side that is attached to a second tab marker by a second frangible line. The pull tab portion overlays at least one detent that marginally biases the pull tab portion away from the lid surface.

Arrangements are provided for smart functionality with dumb containers, such as for determining medication adherence, tracking product use, and validating product authenticity. An acoustic emitter is engaged with a container or other vehicle. Opening the container causes the acoustic emitter to produce an acoustic emission, without requiring power, processing capacity, or sensors. A cell phone or other station receives and registers acoustic emissions, such as by logging opening of the container, verifying authenticity of the acoustic emission, communicating with an oversight system, or similar. Data as may be encoded in an acoustic emission may include vehicle detection data (e.g., logging a container being opened), vehicle information (e.g., lot number, contents name), vehicle validation (e.g., valid or counterfeit numerical code), and audible user recognition (e.g., brand jingles, warning sounds).

An insulating container can be configured to retain a volume of liquid, and include a first inner wall having a first end having an opening extending into an internal reservoir, and a second outer wall forming an outer shell. The opening can be sealed by a closure, the closure having an upper portion with a handle that has a circular curvature equal to the cylindrical portion of the closure. The closure may also have a lower portion that is joined to the upper portion by an injection molded polymer element. The closure may also be in the form of flip type of closure such that the lid can be selectably opened or closed by the user by rotating a flip closure into either the opened or closed position. The closure may also be a two-part lid having a lower cap that may be configured to be removably-coupled to the container and an upper cap that may be configured to be removably-coupled to the lower cap.

The purpose of the invention is to provide a heat insulating container capable of suppressing the deterioration of heat insulation performance even if the volume of an object stored is reduced. A heat insulating container 1 includes a storage space 13 formed by a bottom wall 11 and side walls 12, a container body 10 having an opening 14 continuous to the storage space 13, and a deformable plate-shaped lid 20. The lid 20 is configured such that at least a part thereof is deformed in a state of being inserted into the storage space 13 through the opening 14 of the container body 10 thereby to bring peripheral edges 21 thereof into close contact with the inner surfaces of the side walls 12 of the container body 10.

A single-walled disposable cooler can include: a body including a base and a plurality of support walls coupled to the base, the plurality of support walls and the base defining an interior cavity of the body, and the plurality of support walls extending upwardly from the base to form an opening at an upper terminus of the body in fluid communication with the interior cavity; and a lid configured to reversibly couple with the body, the lid shaped to cover the opening of the body. The body can be made entirely of a pulp-based material.

A two-piece spill proof open cup is disclosed comprising a container suitable for holding liquids, such as a beverage, and a lid. The container has a sidewall, a neck adjacent the sidewall and an opening defined by the neck. The neck has a flange along an edge of the neck and a plurality of posts adjacent the flange. The lid is adapted to fasten to the container. The lid has an upper surface external to the two-piece spill proof open cup and a lower surface internal to the two-piece spill proof open cup. The lid also has a flap, a lid body with a vent, a hinge connecting the flap to the lid body, a handle on the upper surface and a bead having channels. The bead is integrated into the lower surface. The lid flap is adapted to form a liquid tight seal between the lid and container.

The container with a lid and threaded closure mechanism includes a receptacle having a mouth surrounded by a thread, a lid, a sealing ring and a closure mechanism formed by a disc with a hollow interior and a perimetral tubular skirt provided with an engagement configuration complementary to the thread of the receptacle. The closure mechanism surrounds the lid and holds it against the mouth of the receptacle by means of a threaded attachment between the engagement configuration of the closure mechanism and the thread of the receptacle, assuring proper hermetic closure of the lid with the receptacle in cooperation with the sealing ring. The lid and the closure mechanism have mutually engaging elements with a complementary non-circular geometry and size, with both elements being tightly fitted preventing relative rotation of the closure mechanism with respect to the lid.

A closing unit for closing a throughflow opening provided in a wall of a container, comprising: an inner closing element configured to be mounted on the edge of the wall all around the throughflow opening, wherein the inner closing element is further configured to connect in mounted position against at least the inner side of the wall and is provided with a passage for the content of the container; an outer closing element configured to be coupled releasably to the inner closing element for the purpose of closing the passage provided therein; wherein both the inner closing element and the outer closing element comprise a screw thread coupling for screwing the outer closing element onto the lower closing element; wherein the outer closing element comprises a peripheral press-on edge which is embodied to clamp the outer closing element against the outer side of the wall of the container when screwing.
