A coupling device is disclosed for coupling a container to a closure. The container has a container sidewall extending between a first container end and a second container end. A container undercut is defined in an outer surface of the container sidewall. The closure has a closure sidewall extending between a first closure end and a second closure end. A closure outer sidewall is located radially outward from the closure sidewall and defines a slot between the closure sidewall and the closure outer sidewall. The second container end is received within the slot of the closure. A major projection and a major depression are located between the second container end and the slot of the closure cooperating for securing the closure to the container. A minor projection and a minor depression located between the container sidewall and the closure sidewall for cooperating for additionally securing the closure to the container.

Laminated barrier films that include a PECVD barrier coating of diamond-like carbon are disclosed, along with a method of manufacturing such films, and edge-covering strips made from such films, in particular intended for liquid carton packaging are disclosed. Packaging containers that include the edge-covering strip and in particular to a packaging container intended for liquid food packaging are also disclosed.

Described is a multi-part device for keeping consumables such as dietary supplements in separate, non-contaminatable, individually accessible container compartments. The device of the invention can also be used for storage of other items, as well. The top of the device is removable, has several interconnected lids that are attached and retained to the container portion of the device by a rotable cap, the position of which selects which lid, if any, can be opened by a user. The compartment lids separate the contents stored in the various compartments so as to keep the contents of each compartment from being contaminated by items or materials placed in other compartments or from the environment. The safe can be locked shut by rotating the cap to predetermined positions.

A container includes a containing portion that is a closed space that stores contents, and also includes a container main body including a body portion that surrounds the containing portion and also including a handle portion that protrudes from the body portion. The container main body includes a main-body forming sheet member in which a plurality of film layers are stacked. The main-body forming sheet member includes a non-attached region in which the plurality of film layers are partially not attached to each other, and also includes a filling portion in which a filler is contained between layers of the plurality of film layers of the non-attached region. The filling portion includes a first filling portion formed in the body portion and a second filling portion formed in the handle portion. The first filling portion and the second filling portion communicate to each other.

A bottle for adaptive reuse includes a bottle body defining an open interior configured to hold a substance therein. A chamber is formed into the bottle body at least in part by a wall between the open interior and the chamber. The chamber is selectively isolated from the open interior of the bottle. A sealing plate at least partially defines the chamber and an outer surface of the bottle. A threaded structure secures the sealing plate to the bottle body.

A container system comprising a hollow body defined by a continuous outer peripheral wall having a first cavity and a second cavity opposing the first cavity and separated by a dividing wall, a neck opening into the first cavity and a wider open mouth at the end opposing the neck for receiving a base container therein having a lid that engages the inner surface of the outer peripheral wall to secure the base container in the mouth and substantially seal the second cavity.

A waterproof prestressing structure of water bottles or cups, which mainly has a first main body and a second main body, and one surface of an elastic body is integrally provided on the first main body. When the first main body and the second main body are screwed to connect with each other, since the one surface of the elastic body is fixed on the first main body, the one surface of the elastic body connected to the first main body does not deform, and only another surface that contacts the second main body deforms, so that the elastic body does not excessively deform in a tight state, thereby reducing twist or damage of the elastic body caused by screwing. The elastic body is integrally provided on the first main body, so that there is no gap between the elastic body and the first main body.

A drinking bottle includes a first bottle part (10) having an interior (100) for receiving a beverage (G) and a second bottle part (11) having an interior (110) for receiving the beverage (G) and having a bottle opening (13) for dispensing the beverage (G) from the interior (110), wherein the interiors (100, 110) of the two bottle parts (10, 11) are or can be brought into fluid communication with each other. The drinking bottle (1A-1D) has at least one configuration in which the two bottle parts (10, 11) are inclined to each other. The invention also relates to a valve for a drinking bottle. In this way, a drinking bottle can be provided which allows a user to drink in a particularly comfortable position.

Tamper resistant systems and devices and methods of forming the same are disclosed. A tamper resistant system includes a container having a container body defining a cavity having a threaded opening therein, a threaded closure removably covering the threaded opening, and a frangible component including a length of material having a first end and a second end. The first end is integrated with the container body such that the frangible component and the container body have a single piece construction and the frangible component extends from the container body. The second end is coupled to the threaded closure. Subsequent removal of the threaded closure from the container causes damage to at least one of the frangible component, the threaded closure, and the container body. The frangible component, the threaded closure, and the container body are at least partially constructed of an environmentally friendly material.
