The present invention relates to a disposable folding paper cup that folds flat and, when unfolded by the pressing of a folded portion, has a cylindrical upper end, the paper cup comprising: a cup body, which is made of a coated paper of which the inner surface is coated with a cup body coating layer, forms a cylindrical shape when unfolded, and forms a flat surface when both sides thereof are folded at folding lines; bending lines forming oval press parts that unfold bisymmetrically around each folding line when the folding line height center portion of the cup body is pressed, and dividing the oval press parts, spaced from the upper and lower ends of the cup body, therefrom; a bottom sheet which is a coated paper having a bottom sheet coating layer formed on the surface thereof so as to be fused with the cup body coating layer at the inner side of the lower end of the cup body, of which both ends are primarily fused therewith while the bottom sheet is folded along a transverse center folding line that is upwardly convex, and which is fused with the bottom edge of the folded cup body to form a bottom fused band; and fusion columns at which the front and rear surfaces, having the folding line at the center thereof, and the bottom sheet, having the end portion fitted therebetween, form a column shape higher than the fusion height of the bottom fused band and lower than the lower end of the bending line, thereby fusing, at a portion at which the bottom fused band and the folding line meet, the end portion of the bottom sheet through the three sides altogether.

A method and apparatus for the formation of double-walled containers with the structure of two integrally connected and adjacent 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 conformingly and stretchingly assume the tubular blank to the shape of a first dual-container shaped mould cavity set in order to form a stretch-blow moulded first container integrally connected to a second container, with both containers extending in opposite directions. Next, additional heat-conditioning is applied to further heat-condition as necessary the stretch-blow moulded second container and if deemed an advantage, at least part of the first container. Then at least one profiled inversion piston shaped as a male mould member with an outer surface configuration that defines the inner surface configuration of the article being formed and a second container shaped mould cavity set with a single-container shaped configuration are provided along with one or more wall stability devices which are applied to at least part of the wall surface(s) of either or both of the two integrally connected stretch-blow moulded 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 at least partially inside-out, while at the same time 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 wine glass includes a separate top portion and a bottom portion that can be joined together to form a single wine glass. The top portion has a drinking rim opposite a lower rim and the top portion has an enclosed bottom opposite and upper rim. The lower rim of the top portion and the upper rim of the bottom portion join together to form a leak-proof drinking vessel or cup of the wine glass. When separated, the top portion and bottom portion can be nested together. Additionally, a plurality of such wine glasses can be nested together, so that a large number of wine glasses can be packaged together for economical storage and shipping. The wine glass can be disposable and biodegradable or compostable, as examples.

The present invention is a bottle that can be transformed into a glass. The bottle includes a first portion for holding a first serve of a beverage, and a second portion adapted for holding a second serve of the beverage. The second portion and the first portion are configured to removably engage to each other using an engaging mechanism. The bottle further includes one or more closure members that removably engage to the second portion or are retained within a void region within the first portion. Further, when the bottle is in use, the closure member is removed and connected on top of the first portion to form the glass in order to consume the first serve of the beverage contained therein, and if needed, refill the glass with the second serve of the beverage contained in the second portion.

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.
