摘要:
A sealing system is for containers, in particular of the type that envisages sealing with an aluminum cap. Forming equipment of a cap or seal of weldable sealing material is for the application on the mouth of a container. The equipment includes at least one forming device (52) of the seal or cap, the at least one forming device (52) is arranged along the periphery of a forming roll (31) tangent to and moved in sync with a positioning roll carrying at least one disc or sheet of the sealing material for forming the seal or cap.

A method, a shaping tool and a machine for assembling a tubular cardboard body (1) and a flat sealing structure (6), forming a security membrane, surrounded by a peripheral strip, able to be folded down, that is sufficient to suitably assemble the sealing structure with the inner lateral wall of the tubular body, with a grippable tongue (7) folded down toward the central part of the sealing structure, on the face not designed for sealing, inserting the sealing structure in a shaping tool and shaping it in the form of a basin, the peripheral strip becoming orthogonal to said central part, inserting the structure in the tubular body using said shaping tool, configured for sealing said strip with the exception of an unsealed part thereof, extending over the circumference of said strip.

The invention relates to a method for manufacturing packages comprising a tubular body made from a cardboard material and a sealing structure made from a cardboard material, and machines implementing said method, comprising supplying a sealing unit (2) with preformed tubular bodies, two by two, and with sealing structures in the form of flat portions, two by two, each one comprising a central part with a shape conjugated to the shape of the opening of the tubular bodies, surrounded by a peripheral portion that can be folded down that is sufficient to assemble a sealing structure sealably with the inner side wall of the tubular body, inserting pairs of sealing structures into a forming tool (7), and forming them in a bowl, inserting, placing and sealing bowls in the tubular bodies using said forming tool; transferring, two by two, the tubular bodies assembled to the sealing structures to a finishing unit (10), if the sealing structure is a lid, precutting (14) the side wall of said tubular body and partially precutting said lid along a peripheral line, at least one finishing operation for the end of the package bearing said sealing structure.

A cup making machine has a bottom finishing station provided with a mandrel for holding a sidewall blank and a bottom blank such that a flap portion of the sidewall blank is folded around a lip of the bottom blank. The bottom finishing station has a seam clamp engageable with overlapped edges of the sidewall blank to form a side seam, and a clamp ring selectively movable into engagement with the seam clamp. The clamp ring includes an annular wall forming a recess for receiving a rotatable tool 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.

Methods and systems for forming hinged starch-bound matrices. Starch-based compositions are molded between heated molds in order to form a cellular matrix and also to remove the water from the starch-based compositions in order to form a binding matrix of solidified starch. The molding apparatus is configured to form one or more creases within the hinge area in order to define one or more lines upon which the hinge will bend. The molding apparatus is also configured such that the region of the mold corresponding to the inner surface of the hinge area will transfer heat more slowly to the inner hinge surface, resulting in reduced thickness of the skin of the inner hinge. This increases the collapsibility, or ability of the inner surface of the hinge to fold or buckle, during the bending action. This in turn reduces the bending radius of hinge such that the hinging action exerts less strain on the outer surface of the hinge. The inner surface of the hinge may optionally be treated with glycerin or other polyols soften the inner surface. The outer surface of the hinge may optionally be coated with an elastomeric material, such as polyvinyl alcohol, in order to strengthen the outer surface and reduce its tendency to fracture during the hinging action.

Compositions, methods, and systems for manufacturing articles, particularly containers and packaging materials, having a highly inorganically filled matrix. Suitable inorganically filled mixtures are prepared by mixing together an organic polymer binder, water, one or more aggregate materials, fibers, and optional admixtures in the correct proportions in order to form an article which has the desired performance criteria. The inorganically filled mixtures are molded to fashion a portion of the mixture into a form stable shape for the desired article. Once the article has obtained form stability, the article is removed from the mold and allowed to harden to gain strength. The articles may have properties substantially similar to articles presently made from traditional materials like paper, paperboard, polystyrene, plastic, or metal. They have especial utility in the mass production of containers, particularly food and beverage containers.

Compositions, methods, and apparatus for manufacturing sheets having a highly inorganically filled matrix. Suitable inorganically filled mixtures are prepared by mixing together an organic polymer binder, water, one or more 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 controlled, pressed, scored, perforated, folded, and glued to fashion articles for the sheets. They have especial utility in the mass production of containers, particularly food and beverage containers.
