DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
This invention relates to the packaging of various substances, especially foodstuffs, in closed containers.
BACKGROUND ART
A variety of systems are known for packaging foodstuffs in closed containers and a few of the known systems will now be described.
For packaging solid foodstuffs, for example cakes, it is known to use lidded boxes formed from cardboard blanks, the lids either being made integral with or separate from the box, by being folded from the box blanks or being folded from lid blanks separate from the box blanks. It is alternatively known to mould paperboard, plastics, or metal foil, to form solid-foodstuff-receiving trays which may have one or more receiving compartments, and then to wrap the foodstuffs and the trays in plastics or metal foil.
For packaging liquid foodstuffs, where fluid-tightness is important, it is known to fit paperboard or plastics lids in a fluid-tight manner on cups of plastics or paperboard, the paperboard having at least at its inside a liquid-tight layer, for example a thermoplastics relatively impervious to the liquid foodstuff. It is known alternatively to fold a paperboard blank coated on at least one side with a liquid-impervious layer into the form of a side-and-bottom-sealed open-topped carton, with that one side, at the inside of the carton, and then to fill and top-seal the carton.
EP-A-0274280 discloses a system of packaging of foodstuffs in containers of rectangular horizontal section. The containers are formed by folding and side-and bottom-sealing blanks of paperboard coated on both sides with thermoplastics. Each open-topped container is sterilized, filled, and closed with a sterilized closure. The closure is of a laminate including a thermoplastics layer of sufficient thickness to fill an internal discontinuity of the container mouth during heat-sealing of the closure to the container. In making the closure, a portion of laminate is partially severed to form a flap and the laminate is clamped around the flap and drawn to form a shallow dish, to the inside of the base of which is heat-sealed a diaphragm including a pull tab. The thermoplastics layer of the closure is on a reflective metal layer and incorporates infrared-absorbing particles and infrared-reflective particles. Among the drawn zones are transverse rectangular slots which facilitate drawing of the laminate material without splitting, in spite of the sharp corners of the rectangular shape of each drawn zone. However, the presence of the slots can result in undesired deformation of the material among the slots on drawing, because of insufficient support for the material bounding the slots.
GB-A-998242 discloses an apparatus for turning match books which are being transferred one after another from a book-match-making machine to a packing station. A guideway connects the output of the machine to a turning chamber and an endless chain advances the match books in line along the guideway to a guide which maintains the match books upright in a vertical position. Above the guide is a microswitch the movable contact of which depends into an opening in the guide. After the match books have been advanced to a position under the guide, they are clamped, one-by-one, by a feeding slide which rapidly advances them past the microswitch, thereby to operate the same, to the turning chamber, in which they are turned into horizontal positions by means of jets of compressed air, after which they are ejected by a plunger into an arcuate chute forming a downwards continuation of the turning chamber. The compressed air jets are provided by four pairs of nozzles, two pairs arranged one above the other at one side of the turning chamber and the other two pairs arranged one above the other at the opposite side of the turning chamber, the four nozzles at the one side being directly opposite the respective four nozzles at the opposite side. Since the match books have a profile which is wedge-shaped, every second match book is turned in a sense opposite to that in which the other match books are turned
