A cup having a cup opening surrounded by a rim, a bottom opposite the cup opening, a longitudinal axis extending from the cup opening to the bottom, an upper portion disposed closer to the rim than to the bottom and having an outer surface and an inner surface, the upper portion either having a constant diameter or the upper portion being frustoconical and tapering from an upper diameter to a lower diameter, an intermediate portion disposed between the upper portion and the base, the intermediate portion having an outer surface and an inner surface, the intermediate portion either having a constant diameter or the intermediate portion being frustoconical and tapering from an upper diameter to a lower diameter, each diameter of the upper portion being greater than each diameter of the intermediate portion, wherein a sequence of characters is provided on the outer surface of the upper portion projecting above other portions of the outer surface.

A method of forming an article by controlling the thickness of a portion of the plastic composition which comprises a layer of molten plastic composition between opposite first and second solid skins, so that the thickness is constant with a very low tolerance of +/−0.5%, preferably +/−0.2%, when the portion is subsequently exposed to a reduced pressure to cause expansion of the layer of molten plastic composition to form a core layer of expanded cellular foam between the first and second solid skins, and by controlling the stretch of the first solid skin to be within the range of 0.5 to 3%, the expansion of the plastic composition can be highly uniformly controlled in the expanded wall parts.

A molding tool (1000), in particular a thermoforming tool, for producing a container (10) is provided. The molding tool comprises a mold bottom (200) and a mold insert (100) receiving the mold bottom (200), wherein the mold insert (100) is constructed of at least two mold insert parts (110, 120) that together with the mold bottom (200) define a cavity (300) provided for reshaping a two-dimensional web of material into a container, wherein a first mold insert part (110) is mounted stationary in the molding tool (1000) and a second mold insert part is axially movable in the molding tool (1000).

A double-walled container apparatus 12 with the structure of two integrally connected and adjacent containers 14 and 15 extending in the same direction with an air gap 16 between them, formed as a single body out of thermoformable material, and of a thin-walled nature suitable for mass-production, and whereby at least one or more apertures 13 are formed in at least one or more container walls to enable egression of fluids. A double-walled container apparatus 12 may have an upper lid 18 and/or a double-walled container apparatus 12 may have a lower lid 20.

Process for obtaining a container of a given shape starting from sheet material, by providing a sheet; providing a mould having a forming cavity, which defines a reference axis (R) and has a shape corresponding to the given shape of the container; positioning the sheet over forming cavity; providing a forming device having forming structure arranged on a side of the sheet opposite the forming cavity, and operating the structure for inserting the sheet into the forming cavity to deform it until a container blank is obtained having a shape approximating the given shape; and blowing a gas under pressure into the forming cavity to deform the container blank until the container with the given shape is obtained.

The present paper cup comprises a cup body, and the cup body comprises inner paper and outer paper. There are hollow bulges on the outer paper, and the outer paper forms a connecting part. The inner side of the connecting part bonds to the outer side of the inner paper, and the cup rim of the outer paper extends to the cup rim of the inner paper. In addition, the outer side of the cup rim of the inner paper bonds to the inner side of the outer paper, and both cup rims of the outer paper and the inner paper bend outward to form a double layered crimping. The manufacturing process for the present paper cup includes: paper preparation, rolling, composition, sheet cutting, forming, molding and etc.

A pressure forming machine is provided. In one embodiment, the pressure forming machine integrates a heater in its pressure chamber, so the heater and pressure chamber are movable together with respect to a base of the pressure forming machine. The pressure chamber and base can contain locking mechanisms to create a seal between the pressure chamber and a plastic sheet used for forming. The base can also contain a separable air compressor component, so the air compressor can be physically distanced to reduce the noise experienced by a user. Other embodiments are provided.

A package (10) is provided and comprise a frame (15) formed from a plastics material and a wall (20) formed from a paper or paper-based material.

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.
