A portable pet canteen having a flexible bladder with peripheral edges and defining a footprint, an upper wall of the bladder defining an upper mouth, and a cavity being formed within the bladder. A rigid inner scaffold is secured to the upper mouth of the bladder and extends into the cavity. The inner scaffold has a height defined by side walls, the side walls having apertures for passage of water. An upper lid secures to an upper edge of the rigid inner scaffold such as with mating threads to form a closure such that the portable pet canteen is watertight. Water may be retained within the bladder until such time as the upper lid is removed and the canteen placed on the ground for the pet to drink from within the inner scaffold which provides a relatively wide opening. The canteen may be placed within a flexible outer cover for protection, which can also have various handles or straps for ease of transportation.

A collapsible vessel for containing fluid comprises at least two interconnected tubular sections which are configured to move axially with respect to each other upon application of a substantially axial force thereto. The vessel is manipulatable between a collapsed configuration in which the sections are substantially nested to form a tube having a first length and an extended configuration in which the sections form a continuous tube having a second length which is greater than the first length. The vessel comprises locking means configured to be reversibly locked while the vessel is in the extended configuration upon the application of a rotational force to at least one section.

A collapsible cup has a tubular body having an upper end and a lower end, centered on an axis, and formed with a plurality of helicoidal ridge formations spaced angularly around the tubular body and each extending between the ends of the body. A floor of greater rigidity than the body closes the lower end of the body. A ring reinforces the upper end of the body. The body and ridges are formed of an elastically deformable synthetic resin such opposite angular twisting of the upper and lower ends axially compresses together the upper and lower ends and moves upper end down close to the lower end.

A collapsible vessel reconfigurable between expanded and collapsed configurations. A sleeve combination has an inner sleeve rotatable relative to an outer sleeve. A liner is retained by the sleeve combination. The sleeves have opposed major walls divided by opposed fold line formations. Arrays of flexion apertures span a lateral range from adjacent to the respective fold line formation toward a central portion of the major wall, and an aperture density can vary generally based on distance from the fold line formation to promote a true-round confirmation of the expanded vessel. A lid structure with a disk and opposed retaining tabs can be selectively engaged with the liner, and a retaining strap can be pivotally coupled to the sleeve combination with a first orientation encircling the sleeve combination and a second, longitudinal orientation. A storage bag with first and second longitudinally-disposed stays can receive and further compress the vessel.

A novel collapsible cup system that has a cup, a lid, a straw, and a band. The collapsible cup system in the collapsed or dosed form, is more easily stored, better for transport of the collapsible cup system, and prevents the loss or misplacement of the different parts or components of the collapsible cup system. In the closed form, the collapsible cup system has a smaller footprint, which saves storage space. The smaller footprint also allows easier transport of the collapsible cup system.

It is common for the organizers of endurance sports to provide aid stations along the route where participants may receive water to prevent dehydration. To reduce waste at these events, organizers encourage ‘cupless’ races that requiring participants to carry their own vessels. The present invention comprises a hat with a visor, such as a baseball style cap, with a collapsible drinking vessel integrated into the visor. During the course of the race, a runner may encounter a water stop and require a vessel to contain the liquid for immediate consumption. At such time the runner can simply remove their hat and configure the vessel to the open position to receive the liquid. Post-consumption the vessel is configured back to the closed position and becomes seamlessly integrated into the visor with no negative effects upon the runner.

A collapsible jug includes an upper member defining an opening and having a spout at a first side of the upper member. The jug has a lower member defining a base, and a collapsible side wall extending between the upper and lower members. The jug has a link that has a first end pivotally attached to the upper member at a second side of the upper member. The container is alterable between a collapsed configuration wherein the side wall is collapsed and a second end of the link is releasably attached to the spout such that the lower member is releasably retained between the link and the upper member and an in-use configuration wherein the side wall is extended and the second end of the link is releasably attached to the lower member such that the upper and lower members are releasably retained in a spaced apart configuration.

A collapsible container, in particular a drinking cup, includes a cup-shaped element (2), made from a flexible deformable material, having a lower base part (3), a top part (4) with an opening (4) and side wall sections (5a, 5b, 5c, 5d) arranged therebetween. The side wall sections (5a, 5b, 5c, 5d) can be folded towards each other along fold lines (7, 8) formed into the material of the cup-shaped element (2). The cup-shaped element (2) can be folded together by twisting the base part (3) to the top part (4). The fold lines (7, 8) are oriented so that the cup-shaped element (2) constricts, as a result of torsion, between the base part (3) and the upper part (4) when twisting the base part (3).
