摘要:
A wrapper is formed of a semi-rigid section is fixed to a pleated section made of a thin flexible sheet. The semi-rigid unpleated section is folded to form a cavity for containing loose products. The pleated section is deployed around the cavity to form a self-closing wrapper. After opening the wrapper the products may be consumed from either section. The wrapper is particularly suited for french fries or pizza pies.

A napkin (25) combined with a fast food container is placed on the plane portion (14) of the container and held in place by a sheet (18) which covers all or part of the napkin (25) and which extends beyond the napkin (25) at points permitting its attachment to the portion (14) of the container. This assembly constitutes the plane portion (32) of the container; when the container is being used, the napkin (25) stays in place until the consumer removes it from its housing consisting of the sheets (14) and (18) before eating. This concept is applicable to various existing containers.

The bag is made from a pleated sheet comprising asymmetrical pleats and it comprises a closure consisting of two flaps (26, 27) fixed to each other at their ends which are urged to apply against each other when the pleats of the bag are unfolded forcing the flaps (26, 27) to adopt a concave shape which maintains one against the other without any other linking means.

Wrapping for convex or similar bodies, made from a thin sheet, consisting of symmetrical folds, from which there are obtained, by folding, changes in direction making it possible to approximate, as best as possible, the profile to be wrapped and the folds of which are fastened at their ends. In order to change the direction of the folds, each rectangular strip (9 ) is folded on itself along an oblique line (12) enabling the internal (10) and external (11) arrises to be inverted in order to become, respectively, external arrises (13) and (14), the angle (15) formed by the oblique folding line (12) and the internal (10) and external (11) arrises determining the variation in the direction of the folds.
摘要:
Manufacturing method to make simultaneously two paper containers having a front surface and a rear surface, opposed at their support base by three superimposed strips of paper, the intermediate strip being shaped like a sheath sandwiched between the other two strips on which longitudinal folds are formed which, after the containers are separated, serve as a reinforcement of their support base. The invention also includes the device for implementing the method, as well as the containers thus obtained.
摘要:
A package made from a flexible pleated sheet with a central region reinforced by the addition of a second pleated sheet. Folding and unfolding is made easier by having a central area with semi-extended pleats with a side area having flattened pleats.
摘要:
The present invention relates to the description of machine-assisted production assemblies and to the optimization thereof, said assemblies having, built therein, a patented device for folding into deep coated folds, thus making it possible to create paper packaging for fast food, said assemblies all comprising a folded element from a folded paper strip 31. Said machines are modular and all comprise, upstream, an assembly of modules 5, 6, and 7 that supply a folded paper strip 31 that is then converted in a specific finishing module 8 for making, from said lidded paper strip, a packaging for a sandwich or loose product such as fries or chicken pieces.

摘要:
The device is constituted by rectangular reinforcement pieces made from a strip of semi-rigid material, fixed on a thin flexible sheet on the median portion of the zones and mutually articulated by hinges located astride the folds separating the zones.
摘要:
Cup made from a rectangular sheet folded to form a convex base consisting of two isosceles triangles with a common base. The ends of the common base extend into two areas in the shape of deformable lozenges for folding and unfolding the cup while leaving the base flat. When the cup is unfolded by pressing on the edges to draw them together, the ends abut on the edges of the dihedrals forming the cup sides, thereby locking the cup into an open position.
