An apparatus and method for separation of air from fluids, whereby a contractable partition, a throat seal, and air vents are provided, which allow an inside portion behind the contractable partition to expand into or contract from an outside portion, increasing or decreasing the side of the inside portion to accommodate changing volumes of beverage, thereby preventing the entry of contaminating air and slowing the loss of carbonation of the remaining beverage.

A child resistant container that is foldable and comprises a child resistant closure system, wherein the container is capable of storing and securing a variety of objects and substances of different sizes, shapes, and other characteristics. The closure system is adapted for securing the container in a folded position that securely maintains the contents of the container. The closure system generally comprises a cap selectively removable relative to a neck portion of the closure system. The closure system may further comprise a tether for permanently or semi-permanently attaching the cap to the container. The neck portion being adapted for projecting through hole members provided in the container, such that projecting the neck portion through the hole members and fastening the cap to the neck portion selectively secures the container in a folded position.

A bottle is provided for storing an associated fluid product when filled. The bottle includes a first wall having an opening therein that is selectively opened and closed to allow the associated fluid product to be dispensed therethrough or stored in the bottle, respectively. A second wall is spaced from the first wall, and a third wall extending between the first and second walls. A compliant pleat extends along substantially an entirety of the first wall, second wall, and third wall and divides the bottle into first and second portions. The compliant pleat allows the first and second portions to move toward one another in response to a predetermined force and thereby increase pressure in the closed bottle.

A container for pourable foodstuffs has a base, a side wall connected to the base and surrounding a storage chamber. An elastic cuff is connected with a first end to the side wall and has a second end with an opening. The cuff width decreases from first to second end along a longitudinal container axis. The elastic cuff can be pushed into and pulled out of the storage chamber. A sealing element shaped as a stopper can be inserted into the opening for closing the container and has a shank portion matched in shape and size to the opening such that sealing abutment of a shank portion surface against surfaces of the elastic cuff adjoining the cuff opening is established in a contact region of the shank portion when the stopper is inserted. The shank portion has an end with a thickened portion thicker than the contact region.

A fastening belt for a recyclable, plastic, beverage bottle including: a length of flexible material affixed around a circumference of the bottle and positioned on a lower part of a body of the bottle; in a first partially compacted the material is disposed in a crease of a fold between the first and the second segments of the bottle; and in a second, compacted state, the material is configured to be passed over the neck of the bottle, thereby securing the first and second segments of the bottle in the compacted state folded over the third segment.

A bottle made of PET which can be filled with a hot, warm or cold liquid has a neck, a body and a closed bottom. The body has a peripheral groove for pressure relief capable of collapsing in a controlled manner under the bias of an externally applied vertical axial load. The structure of the groove is such that after collapsing the bottle will not be able to resume its original shape unless it is subjected to the application of another external force of sufficient strength in reverse direction with respect to the force which was applied to obtain the collapsed shape.

A container consisting of plastic material that is produced using the blow, fill and seal method and the filler material of which, enclosed by a container wall (15, 20), can be autoclaved, is characterized in that at least one shaping means (19, 21, 23, 25, 29, 33) is provided in the container wall (15, 20), which ensures, despite a low relative air volume in the container, that when administering the filler material by infusion the container wall (15, 20) collapses at least partially reducing the volume, without aeration of the container.

Collapsible household containers having a foldable wall section with shape-retaining characteristics are disclosed. In particular, collapsible laundry baskets, buckets, colanders, dish drainers, cups, and bottles are provided. The folding region may include foldable tiers of a flexible material, each tier having at least one stable, relatively expanded position and at least one stable, relatively collapsed position; and an intervening, non-folding tier composed of a different, relatively rigid material.

A shaker bottle (10, 20) comprises a vessel (11) for retaining a liquid volume, a lid (12) for closing said vessel (11), a container (31) for storing a powder supplement, and an accessory compartment (16) for storing valuables. The container (31) is releasable arranged to means (40) fixed to a lower surface (41) of the lid (12). The vessel (11) is foldable for providing a folded state of the shaker bottle (10, 20) during transportation. The container (31) is received by the bottom (17) of the vessel (11) in the folded state, and thus the release of the container (31) is locked. In an unfolded state the container (31) is released for supply of the powder supplement to the liquid in the vessel (11), while the container (31) is serving as a stirring device. A method for use of the shaker bottle (10, 20) is provided for securing a safe storing of powder supplements during transportation and for improving the functionality of a shaker bottle (10, 20) for every user with an active lifestyle.

The present invention relates to a partially collapsible dispensing container (100) extending along a longitudinal axis (110) between a first end and second end, the container comprising an opening (20) for dispensing fluid at said second end, wherein the container (100) comprises a collapsible part (102) and a retaining part (101), wherein the collapsible part and the retaining part are arranged successively along the longitudinal axis (110) and the collapsible part (102) is configured to collapse at least partially inside the retaining part (101) by the application of pressure substantially in a direction of the container longitudinal axis (110). The invention further relates to a system comprising a partially collapsible dispensing container and further comprising a mechanical actuation device (10) configured to apply a pressure on the collapsible part (102) of the container (100) substantially parallel to the container longitudinal axis (110) in order to allow dispensing of the fluid inside.
