Collapsible household containers having a foldable wall section with shape-retaining characteristics are disclosed. In particular, collapsible laundry baskets, buckets, colanders, dish drainers, and cups 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.

A portable container for transporting and storing a plurality of perishable items including food and beverage items, having a heat-resistant outer tubular member with double-layered insulation in an adjacent inner tubular member to accommodate a plurality of perishable items and to sustain the prescribed temperature of such food and beverage items and to promote longevity thereof. The portable container optionally includes a plurality of external compartments and has removable endcaps enclosing both ends thereof. Each endcap is conveniently removed from a tubular end and then used as a cup for drinking a plurality of beverage items or used as a dish for eating a plurality of food items.

This invention concerns a fluid purification device. The device has container, a nozzle and a removable filter element. The container is preferably a bottle and has at least partially flexible sidewalls so that it is collapsible from a first, operative condition into a second, inoperative condition. The nozzle is connectable to the container and defines a first fluid flow path along which fluid flows when, in use, filling the container and a second fluid flow path along which fluid flows when, in use, dispensing fluid from the container. The removable filter element is carried by the nozzle such that it is positioned in the first fluid flow path so that the fluid is filtered when filling the container and positioned outside the second fluid flow path so that the flow of fluid is unobstructed by it when dispensing fluid from the container. The invention also concerns a method of filtering a fluid.

A cylindrical bottle which collapses along helical groove, ridge and connecting rings along its sidewall. When inward force is applied along the bottle's vertical axis, the helical groove rings and connecting rings fold under the ridge rings and remain substantially locked under the ridge rings, thereby causing the sidewall to collapse and remain collapsed until sufficient outward force is applied. When sufficient outward force is applied along its vertical axis, the bottle extends as the distance between its helical groove rings and ridge rings lengthens. Due to the diamond-shaped cross-section of the connecting rings, in conjunction with the silicone composition of the bottle's body, the collapsing and extension of the bottle occur in sequential segments, creating a unique, playful sound and an amusing worm-like movement.

A receptacle has at least one elastomeric sidewall with a contoured non-linear shape defining a container with a predetermined volume for housing a substance to be contained. The at least one sidewall includes a substance-contacting surface. The receptacle is fully reversibly eversible to transform between a first stable conformation with the substance-contacting surface facing inward and a second stable conformation with the substance-contacting surface facing outward allowing for facile cleaning and drying of the substance-contacting surface. The at least one elastomeric sidewall possesses sufficient structural strength to stand upright in the first and second stable conformations without extraneous support. The receptacle can include a cap and an attachment joint for securing the cap to the elastomeric receptacle.
