Abstract

Manufacturing procedure for making article with a number of separate compartments, consists of forming a basic panel (1) of a plastic material with four zones (Z1, Z2, Z3, Z4) marked with fold lines (2.1 - 2.10) of reduced thickness, fastening a second, smaller panel to the second fold line (2.2), and forming pleats in the basic panel with the additional panel fitting between them. Manufacturing procedure e.g. for making a document file, wallet or purse with a number of separate compartments, consists of forming a basic panel (1) of a plastic material with four zones (Z1, Z2, Z3, Z4) marked with fold lines (2.1 - 2.10) of reduced thickness, fastening a second, smaller panel to the second fold line (2.2), and forming pleats in the basic panel with the additional panel fitting between them. The linked panels are then folded in half along the lengthwise fold line (2.10) to make a series of pockets, and two sets of pockets can be assembled with an outer cover, for example to make a purse.

  PROCESS FOR MANUFACTURING ARTICLE OF MATERIAL

  PLASTIC WITH MULTIPLE COMPARTMENTS

  FOR THE STORAGE OF VARIOUS PRODUCTS AND OBJECTS

  The invention relates to storage articles having various compartments of the type of shutters, sorters, purses and the like. Many articles of this type are already known, essentially made of rigid materials such as cardboard, for filing cabinets, or in leather or imitation leather for wallets or purses. In the latter case, the storage of coins, their constant handling can in the long run alter the quality of the material, with possible deformations of the walls depending on the volume resulting from the products stored and their quantity. Another problem also lies in the price of obtaining this

type of items.

  We also know from the French model published under number 627 998, in a particular application to purses, represented in FIG. 1 of the drawings, defining the general concept of an assembly presenting

  compartment flaps added and fixed to each other by sewing.

  The manufacturing process remains laborious, impractical and costly.

  The invention aims to optimize the manufacture of such an article.

  i L The aim sought after according to the invention was to design a new storage article with several compartments made of a plastic material, flexible and deformable, and of great impact resistance with

manipulation of objects.

  Another goal sought was the implementation of a manufacturing process that is easy to implement, economical and allowing the use of the product.

at low price.

  These goals and others will become apparent from the following description.

  According to a first characteristic of the invention, the method of manufacturing an article with several compartments is remarkable in that it implements the following phases: - Production of a plastic support strip having four successive zones delimited by grooves forming a reduction in thickness, namely transverse grooves in the width direction of the support strip and a median longitudinal groove established in the length direction of the support strip, and in that the crossing of said grooves defines a plurality of distinct zones established on the support strip, each zone having a large side in the transverse direction of the support strip and a small side in the horizontal direction, as well as an end zone established on the half

of its width of the support strip.

  Addition of a second floating strip in the lateral direction of the first support strip, said second floating strip being smooth and ï

  fixed to the first support strip along the second transverse grooving line. Successive folds in a transverse and longitudinal plane of the first support strip and the second floating strip, in order to obtain a fan shape, defining and preforming

  several cells with bellows parts.

  Finishing operation of the item of successive shutters by high frequency 0 welding, in order to obtain a homogeneous item, all shutters

  being in the same plane and defining several compartments.

  These characteristics and others will become clear from the rest of the

description.

  To fix the object of the invention illustrated in the figures of the drawings o: Figure 1 is a view of a purse according to the prior art; - Figures 2 to 9 are views illustrating the different manufacturing phases. In order to make the object of the invention more concrete, it is now described

  in a nonlimiting manner illustrce in the figures of the drawings.

  The article referenced as a whole by (A) is defined from a support strip (1) of flexible plastic material. This is arranged with four successive zones (Z 1, Z2, Z3, Z4), delimited by grooves (2) forming a reduction in thickness and allowing during shaping a

  articulation and folding under the conditions which will be specified below.

  i I1 is first of all made in the zone (Z1) three transverse grooving lines (2.1, 2.2, 2.3) and a grooving line (2.4) separating the zone (Z1) from the zone (Z2). The latter is smooth in its entirety. The zone (Z2) is separated from the zone (Z3) by a transverse grooving line (2.5), then the zone (Z3) comprises three successive transverse grooving lines (2.6, 2.7, 2.8). A grooving line (2.9) separates the area (Z3) from the area (Z4). A longitudinal grooving line (2.10) is established in

  the median plane of the width of the support strip (1).

  The implementation and arrangement of these different successive lines for obtaining different flaps identified with respect to the grooving line (2.10) longitudinal median separation allows the obtaining of flaps (3a-3a ', 3b-3b', 3c-3c ', 3d-3d') in zone (Z1), then (3e-3e ') in zone (Z2), then (3f-3f', 3g-3g ', 3h-3h', 3m- 3m ') on the zone (Z3), and finally only one

  flap (3n) in half the width of the support strip (1).

  It should be noted that the flaps (3a-3a ', 3m-3m') have the same width (11) which is significantly greater than the width (12) of the other flaps (3b-3b ', 3c-3c' , 3d-3d ', 3f-3f', 3g-3g ', 3h-3h', 3m-3m '). Furthermore, the flaps (3rd 3rd ') have a width (13) greater than (11) and (12). Finally, the width (14) of the flap (3n) is greater than (13). These dimensional relationships are established to allow the folded form of the article. All of these

  provisions appears illustrated in Figure 2.

  We now describe the phase of own production and folding, with a view to

of obtaining the article.

  The following phase appears illustrated in FIG. 3 of the drawings and implements the addition of a second floating strip (4) which is arranged and fixed by high frequency welds along the transverse grooving line (2.2) by the part (4b ). Thus, the strip (4) of length equal to the width of the support strip (1) and of a width (15) equal to the width (13) of the flaps (3e

  3 '). The end (4a) of the strip is free at this stage of manufacture.

  The next phase of the process, represented in FIG. 4, consists in making a first group of cells or compartments (A1.A2) by proceeding to the folding of the flaps (3c-3c ') and (3d-d') on the flaps ( 3f-3f ', 3g-3g') forming two bellows, while the strip (4) is fixed by high welds

  frequency along the grooving line (2.7).

  The next phase of the process, shown in Figure S. consists of folding the flaps (3a-3a ', 3b-3b') on themselves, as well as (3h-3h ', 3m-3m') to

  constitute bellows primers.

  The next phase of the process, shown in figure 6, consists in folding down the

  flap (3n) on the part of flaps (3a-3m) opposite.

  The next phase of the process, represented in FIG. 7, consists in folding the article in the presentation phase of FIG. 6 in a folding plane with respect to the longitudinal grooving line (2.10) allowing fan-shaped shaping. The flaps (3a'-3m ') are located opposite each of the faces of the strip (3n) and are then welded by high frequency along

  grooving (2.9) and end (3P) lines, as shown in figure 8.

6 2837420

  In this situation, the flap end edges (3a'-3m '), (3a3m)

  and (3n) extend substantially beyond the connecting line.

  The next phase of the process, represented in FIG. 9, then consists in removing by cutting out the aforementioned projecting parts, in order to obtain an article in the shape of a fan comprising four compartmentalized cells (A1, A2, A3, A4). Thus, the opening or closing of the article allows access or not to

O above-mentioned compartments.

  In a specific implementation of the invention illustrated in FIG. 1, two articles obtained according to the method are arranged adjacent between two articulated support planes (P1, P2), the assembly being capable of constituting a purse. In a particular application, the wallet allows the storage of

Euro coins for example.

  The advantages of the method emerge from the invention. The successive shaping of the folds completed by high bonding operations

  frequency allows a simplified implementation of the product.
