This utility model released one kind of multifunctional flexibly transformable cup, comprising one internally cut-through transformable cup and a nested bottom plug that is sealed and clamped with the transformable cup body. The above-mentioned transformable cup is comprised of a foldable enclosure and pin that are successively cut-through and flexibly and tightly connected. The aforesaid seal clamp for embedded bottom plug is located at the junction between the foldable enclosure and pin. When the multifunctional flexibly transformable cup of the utility model is in use, the folding enclosure body can be overturned freely, and the whole body is made of food-grade flexible silica gel material, which is safe and reliable and not easy to be broken. It can also be used as the wine cup, bottle stopper and the bottleneck inserted into the wine bottle that can be directly used for drainage of fluid, with complete functions.

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 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.

In a general aspect, a multi-piece vessel can include a body defining an interior volume, and a base. The body can include a closed end, and an open end opposite the closed end. The base can have a foot arranged in a plane. The base can include a stem arranged along a longitudinal axis that is orthogonal to the plane, and a first magnetic element disposed at an end of the stem. The multi-piece vessel can also include an attachment assembly coupled with the closed end of the body, the attachment assembly having a second magnetic element configured to form a magnetic coupling with the first magnetic element, and a retention feature defined on a surface of the attachment assembly distal from the body.

A method and apparatus for the formation of double-walled containers includes two integrally connected containers extending in the same direction with an air gap between them, stretch-blow moulded as single bodies out of thermoplastic material, and suitable for mass-production. A thermoplastic tubular blank is formed and then heat-conditioned. The heat-conditioned tubular blank is then mechanically stretched longitudinally and blow-formed outwards by gas pressure to form first and second containers. A piston and mould cavity cooperate to further mould the containers such that the second smaller container side wall(s) are at least substantially not in contact with the second container shaped mould cavity set and may be inverted inside-out, while the second smaller container bottom wall at least substantially does not invert, in order for the second smaller container to become a substantially mirror-image inverted second smaller container extending in the same direction as, and interior to, the first container.

A collapsible container, particularly a cup or mug having a flexible body having a top tier, middle tier and a bottom tier is disclosed. The bottom tier has a base. The container has a first living hinge between the top and middle tiers and a second living hinge between the middle and bottom tiers. A rigid, preferably metal, plate is at least partially embedded in the bottom tier that makes the otherwise flexible base rigid. The container can have a rigid metal cladding around the top tier and a handle made of flexible material. The collapsible container may be made by injection molding.
