摘要:
A cup making machine (20) has a bottom finishing station (40) provided with a mandrel (28) for holding a sidewall blank (60) and a bottom blank (62) such that a flap portion (66) of the sidewall blank (60) is folded around a lip (64) of the bottom blank. The bottom finishing station has a seam clamp (76) engageable with overlapped edges of the sidewall blank to form a side seam, and a clamp ring (86) selectively movable into engagement with the seam clamp. The clamp ring includes an annular wall (88) forming a recess for receiving a rotatable tool (90) which presses against the flap portion and the lip to form a bottom seal. Part of the seam clamp protrudes into the clamp ring, and part of the clamp ring protrudes into the seam clamp to form a bridge acting against the overlapped side seam at the top of the lip.

Compositions, methods, and apparatus for manufacturing sheets having a highly inorganically filled matrix prepared by mixing together an organic polymer binder, water, one or more inorganic aggregate materials, fibers, and optional admixtures in the correct proportions in order to form a sheet which has the desired performance criteria. The inorganically filled mixtures are formed into sheets by first extruding the mixtures and then passing the extruded materials between a set of rollers. The rolled sheets are dried in an accelerated manner to form a substantially hardened sheet, such as by heated rollers and/or a drying chamber. The inorganically filled sheets may have properties substantially similar to sheets presently made from traditional materials like paper, paperboard, polystyrene, plastic, or metal. Such sheets can be rolled, pressed, scored, perforated, folded, and glued. They have particular utility in the mass production of articles, such as food and beverage containers, and packaging materials.

A method and machine (1) for producing a rigid packet of cigarettes from a flat, substantially rectangular blank (5); the blank (5) has two main longitudinal crease lines (29), and a number of transverse crease lines (30) defining, between the two main longitudinal crease lines (29), central panels (19', 20', 19") having respective lateral wings (18, 18"); the flat blank (5) is fed to a prefolding station (S4) where the lateral wings (18', 18") of at least one of the central panels (19', 20', 19") are folded about the respective main longitudinal crease lines (29); and the blank (5) is subsequently restored to the flat configuration before being fed to a follow-up folding station (S2).
摘要:
Compositions, methods and system for manufacturing articles, including containers and packaging materials, from inorganically filled materials are disclosed. Suitable compositions are prepared by mixing together an organic binder, water, and appropriate additives (such as aggregates, fibers, and rheology-modifying agents) which impart predetermined properties so that an article formed therefrom has the desired performance criteria. The desired article can be molded from a sheet. The sheet forming processes require the mixture to first be fashioned into a sheet, such as by the use of an extruder or rollers, after which the sheet is formed into the desired article. Once the article is formed, it is hardened. Printed indica and a coating can then be applied.

Compositions and methods for manufacturing sheets having a starch-bound matrix reinforced with fibers and optionally including an inorganic mineral filler. Suitable mixtures for forming the sheets are prepared by mixing together water, unmodified and ungelatinized starch granules, a cellulosic ether, fibers, and optionally an inorganic mineral filler in the correct proportions to form a sheet having desired properties. The mixtures are formed into sheets by passing them between one or more sets of heated rollers to form green sheets. The heated rollers cause the cellulosic ether to form a skin on the outer surfaces of the sheet that prevents the starch granules from causing the sheet to adhere to the rollers upon gelation of the starch. The green sheets are passed between heated rollers to gelatinize the starch granules, and then to dry the sheet by removing a substantial portion of the water by evaporation. The starch and cellulosic ether form the binding matrix of the sheets with the fibers and optional inorganic filler dispersed throughout the binding matrix. The starch-bound sheets can be cut, rolled, pressed, scored, perforated, folded, and glued to fashion articles from the sheets much like paper or paperboard. The sheets are particularly useful in the mass production of containers, such as food and beverage containers.
摘要:
A heat-insulating container (1) is used for an instant dried food and is excellent in heat-insulating property, design and economy. The container comprises a paper cup body (2) with a bottom (2b), which has an inner surface coated with a polyolefin resin and is provided with an outward curled portion (2c) formed at an upper opening end of the cup body and at least one horizontal rib (2d) formed on a side wall of the cup body so as to project outward therefrom; and an inverse-frustoconical paper sleeve (3) provided with an inward curled portion (3a) formed at a lower end of the sleeve. The cup body and the sleeve are integrally combined with each other so that an upper need of the sleeve is joined to an outer periphery of the side wall of the cup body, which is adjacent to the outward curled portion of the cup body, and an inner surface of the inward curled portion of the sleeve is joined to an outer periphery of a lower portion of the side wall of the cup body.

摘要:
Compositions, methods, and systems for manufacturing articles, particularly containers and packaging materials, having a particle packed, highly inorganically filled, cellular matrix are disclosed. Suitable inorganically filled mixtures are prepared by mixing together a starch-based binder, a solvent, inorganic aggregates, and optimal admixtures, e.g., fibers, mold-releasing agents, rheology-modifying agents, plasticizers, coating materials, and dispersants, in the correct proportions to form an article which has the desired performance criteria. The inorganically filled mixtures have a predetermined viscosity and are heated between molds at an elevated temperature and pressure to produce form-stable articles having a desired shape and a selectively controlled cellular, structure matrix. The molded articles may be placed in a high humidity chamber to obtain the necessary flexibility for their intended use. The articles may be manufactured to have properties substantially similar to articles presently made from conventional materials like paper, paperboard, polystyrene, plastic, or other organic materials. They have especial utility in the mass-production of containers, particularly food and beverage containers.
