A vessel includes an inner container, an outer container, a connector, a cap, and a lid. The outer container includes a first coupler and an outer chamber. The inner container includes a second coupler and an inner chamber to hold a liquid. The inner container is receivable at least partially within the outer chamber. The connector includes a third coupler that is complimentary to the first coupler, and a fourth coupler that is complimentary to the second coupler. When both the first coupler is engaged with the third coupler and the second coupler is engaged with the fourth coupler, the outer chamber is entirely enclosed within a liquid-proof barrier.

An administration unit for a composition comprising a container intended for accommodating the composition and having an opening and a cap for closing the opening. The cap has a projecting separating region to separate off a part of the composition. Mutually corresponding connection means are provided on the container and cap and allow the cap to be connectable to the container in a first storage position and a second separating position, wherein the cap is connectable to the container in the first storage position in such a manner that the opening is closed thereby and the separating region extends essentially along a container outer wall and wherein the cap is connectable to the container in the second separating position in such a manner that the separating region projects from the container, in order to allow a user to guide the separating region by means of the container.

Containers for storing food in a storage compartment may include a base portion of the container. The storage compartment is sealed with a film to get the food stored in the storage compartment fresh. The container further includes a reversible lid that is able to attach to the base portion of the container in two different configurations. In a first configuration the reversible lid attaches to the base portion without affecting the seal created by the film. In a second configuration the reversible lid attaches to the base portion when the lid is inverted and the film is removed from the base portion.

A receptacle closure can include a body, an aperture, a first female threaded portion, a second female threaded portion, and a self-sealing valve. The body can extend along a longitudinal axis between a first end and a second end. The aperture can extend through the body between the first end and the second end. The first female threaded portion can extend from the aperture at the first end and can have a first thread configuration. The second female threaded portion can extend from the aperture at the second end and can have a second thread configuration. The first female threaded portion can be spaced from the second female threaded portion along the longitudinal axis. The self-sealing valve can be disposed in the body between the first female threaded portion and the second female threaded portion along the longitudinal axis.

A fitting for affixing to a mouth of a receiving container comprises a tubular body having a top end, a bottom end and a side wall extending between the top and bottom ends and having an inner surface and an outer surface. A partition is integrally formed on the inner surface between the top end and the bottom end. The partition divides the body into an open top region and an open bottom region. The inner surface of the open top region has a top threading and the inner surface of the open bottom region has a bottom threading. The partition further includes an aperture therein adapted to permit passage of a standard size, disposable straw therethrough from the open top region to the open bottom region.

Some embodiments relate to a cap for controlling fluid flow from a bottle that includes an opening for dispensing the fluid. The cap includes a first section and a second section. The first section defines an orifice and a plurality of air channels. The opening of the bottle is in flow communication with the orifice and the plurality of air channels. The second section includes a first plurality of rings for securing the opening of the bottle, such that at least one of the air channels and the orifice creates an air-lock to secure the fluid within the bottle.

A vessel includes an inner container, an outer container, a connector, a cap, and a lid. The outer container includes a first coupler and an outer chamber. The inner container includes a second coupler and an inner chamber to hold a liquid. The inner container is receivable at least partially within the outer chamber. The connector includes a third coupler that is complementary to the first coupler, and a fourth coupler that is complementary to the second coupler. When both the first coupler is engaged with the third coupler and the second coupler is engaged with the fourth coupler, the outer chamber is entirely enclosed within a liquid-proof barrier.

A reversible cap configured to be removably secured to a dispensing nozzle of a container containing a substance includes a body with a first end and an opposite second end. The first end and the second end of the cap body are each configured to be removably secured to the dispensing nozzle. At least one aperture is formed in a sidewall of the body and is in fluid communication with the second end. The first end, when secured to the dispensing nozzle, is configured to prevent the substance in the container from being dispensed through the dispensing nozzle. The second end, when secured to the dispensing nozzle, is configured to allow the substance to be dispensed through the dispensing nozzle and through the at least one aperture in the body.
