A cover operates with a bistable snap-fit mechanism for positioning on a closable opening of a container or on another element to be closed by the cover. The cover and/or a container wall region has fitted thereon a tamper-evident sealing element to be removed when opening the container for the first time, which, prior to being removed, blocks deformation of the front wall necessary for changeover between the two bistable states and/or prevents an expansion portion necessary for the snap-fit mechanism, from bringing about alteration to the outer circumference of the cover necessary for deformation of the front wall of the cover between the two bistable states. As an alternative, or in addition, it is also possible for a handle member, necessary for pulling off the cover, to be configured such that it can only be used once the tamper-evident sealing has been successfully removed.

A container has an upper edge, a lateral wall extending around the circumference of the container, and an opening closed by a lid. A latching rim proximate the upper edge latches with a corresponding latching rim on the lid. The latching rims of the container and the lid, respectively, extend at least partially around a circumference of the same. The container lateral wall includes a peripheral skirt having a sub-region extending radially outwardly from the lateral wall. The lid includes a lower lid rim on the outside of the container and at least one extension extending outside the lateral wall of the container. The extension extends below the lower rim of the lid and at least partially penetrates the skirt of the container. The extension and the container include corresponding fixing devices releasable independently of the latching devices formed by the latching rims of the container and the lid.

A removable lid for a drinking cup is described. The removable lid has a top side with an ellipsoidal recession having a bottom opening. A baffle wall extends from the perimeter of the bottom opening, and is configured to prevent a beverage from passing through the bottom opening upon sudden movement of the beverage. The ellipsoidal recession may be designed so that a hot beverage being consumed through the removable lid is exposed to more outside air for cooling purposes. The same ellipsoidal recession may be designed to funnel added ingredients into a beverage. The removable lid may have a stirrer opening so that stirrers may be inserted and taken out without lid removal. For additional strength, the surface of the removable lid may be textured to increase its moment of inertia. The bottom opening of the removable lid may be closed using a fitted blocking plug.

Disclosed is a plate cover system having a plurality of plate covers that can be configured to stack upon each other in a protracted configuration and/or or a collapsed configuration. In one embodiment, a first plate cover can be used to support a second plate cover by placing the second plate cover on top of the first plate cover, wherein a volume of space exists between the first plate cover and the second plate cover. The system can be transitioned between the protracted configuration and the collapsed configuration by slidably engaging channels disposed on sidewalls of the plate covers.

An assembly comprising a bucket body having vertical side walls wherein the vertical side walls extend upwards from a closed bottom base. A handle may be connected to the vertical side walls, and one or more ergonomically designed feet may be detachably connected to and extend beyond a bottom surface of the bottom base. Disclosed embodiments may provide an ergonomic grip portion integrally formed with the handle. The handle may be connected to the bucket body via a twist-lock connection assembly.
