Collapsible heatable liquid containers having three non-inverting tiers and two inverting tiers interposed between the non-inverting tiers. The non-inverting tiers are typically formed of a stiff (i.e., stiff or rigid) material that is different from the material of the inverting tiers, which is typically a resilient polymer such as a thermoplastic elastomer or silicone. The bottom non-inverting tier is typically formed of a material suitable for inductive, contact, and flame heating, such as stainless steel. The container may be a liquid vessel suitable for drinking, beverage heating and serving, or cooking, such as a drinking bottle or kettle. A bottle may include an attached cap that engages the top tier to close the bottle, and a kettle may include a pour spout connected to the middle or top tier.

A shaker bottle having a vessel for retaining a liquid volume, a lid for closing said vessel, a container for storing a powder supplement, and an accessory compartment for storing valuables. The container is releasably arranged to a lower surface of the lid. The vessel is foldable for providing a folded state of the shaker bottle during transportation. The container is received by the bottom of the vessel in the folded state, and thus the release of the container is locked. In an unfolded state the container is released for supply of the powder supplement to the liquid in the vessel, while the container is serving as a stirring device. A method for use of the shaker bottle is provided for securing a safe storing of powder supplements during transportation and for improving the functionality of a shaker bottle for every user with an active lifestyle.

The present invention provides a telescopic storage can structure, which comprises a can, a hood and a cover. The can is disposed with an airtight member at an opening, and the hood is covered on the can and formed with an upper opening. The cover is disposed on the upper opening and formed with an air outlet and disposed with an air outlet valve assembly. The hood can be upwardly and downwardly displaced on the can according to a holding capacity, and when the hood is displaced downwardly, the cover will squeeze the internal air thereof and the internal air is sent out through the air outlet. Thereby achieving an effect of being able to adjust a size according to a holding capacity and facilitate an airtight purpose, and further, relative positions of the can and the hood can be telescopically adjusted according to a storage capacity.

Provided is a beverage bottle capable of keeping a carbonated beverage left over therein from going flat. The beverage bottle is provided with a bottle body having a volume-reducing structure capable of reducing the volume of the bottle body, a cap capable of sealing an opening of the bottle body, and a shrunken state-maintaining means provided on the bottle body to cause the bottle body having been reduced in volume to be maintained in the reduced volume state. The volume-reducing structure is configured of helical protrusions and recesses respectively formed on the bottle body, and the shrunken state-maintaining means is provided on a trunk section of the bottle body and is configured with a squeezing means for squeezing and maintaining the trunk section having been narrowed by being squeezed along the helical protrusions and recesses.

The invention refers to a cap assembly (10) used in a container (20) comprising in its inner volume a food product to be dispensed, the container volume being closed by a lid (21), such that the cap assembly (10) comprises two parts (11, 12) relatively moveable with respect to each other, the relative movement and/or the solidary movement of these two parts (11, 12) allowing the following functions: displacement of identification means (22) arranged on the cap assembly (10) and/or on the container surface according to a certain path; opening and/or closing a communication between the cap assembly (10) and the inner volume of the container (20).

A modular interchangeable vessel system is disclosed, which comprises a flexible and flat-foldable waterproof vessel having a sealed end and an unsealed end disposed distal from the sealed end, the unsealed end having a kayak shaped endpiece sealingly coupled thereto.

A rollable heat preservation cup, comprising a cup cover, a fixing ring, a bottleneck, and a two-layered cup body which further comprises an inner-layer cup body and an outer-layer cup body, wherein the two-layered cup body is a rollable and soft cup body, wherein a heat-preserving material layer is disposed between the inner-layer cup body and the outer-layer cup body, wherein a fixing ring is disposed between the bottleneck and the cup body, wherein the upper end part of the two-layered cup body is firmly embedded into an inner space formed by the fixing ring and the bottleneck.

Provided is a method for filling a container with a liquid in which the container is filled via an opening of the container and an internal volume of the container increases during the filling process and the internal volume of the filled volume is at least twice the volume of the unfilled container. Also provided is a device for filling containers, and a container having an opening, a base region, and a main body integrally formed with the opening and the base region, the main body being bent by a specified bending angle around a specified circumferential folding edge of the main body in such a way that the opening of the container is arranged closer to the base region than the circumferential folding edge is, wherein the position of the folding edge relative to the base region of the container can be changed during an expansion of the container.

A container system includes a body having a first end and a second end. The first end has an opening formed therethrough. The body defines a plurality of ribs between the first end and the second end that are configured to actuate between a compressed state and an expanded state to vary a volume inside the body. A dissolvable concentrated material is disposed within the body. When a predetermined amount of water is introduced into the body after the plurality of ribs are actuated into the expanded state, the dissolvable concentrated material dissolves in the water to produce a mixture having a predetermined concentration.

A collapsible bottle with a channelway provided in a side wall which, in collapsed conditions of the bottle, the channelway becomes engaged with opposed portions of the side wall and define a flow passageway therethrough toward a discharge opening at one end of the bottle and a closed other end of the bottle.
