Definitions

  • the present invention relates to a method of making packaging elements of the kind set forth in the preamble of claim 1.
  • the present invention also relates to an equipment comprising press tools and/or counter-press tools for car ⁇ rying out the method according to the present invention, and according to this invention this equipment is charac ⁇ terized by the features set forth in the characterizing clause of claim 10.
  • Figure l in perspective shows an example of a star ⁇ ting material for use in carrying out the method according to the present invention
  • Figure 2 likewise in perspective, shows the star- ting material shown in Figure 1 after having been proces ⁇ sed according to the method of the invention
  • Figure 3 is a partial sectional view along the line III-III in Figure 2
  • Figure 4 likewise in perspective, shows the packaging element shown in Figure 2 together with an article to be packaged placed on and supported by the element
  • Figure 5 is a sectional view corresponding to
  • Figure 6 in perspective shows a lower press platen with a number of lower pressing blocks secured thereto
  • Figure 7 is a sectional view corresponding to the line VII-VII in Figure 6, in addition to the lower press platen shown in Figure 6 also showing another press platen with an upper pressing block secured thereto, as well as the packaging element placed between the two press pla- tens.
  • the starting material shown in Figure 1 and in ⁇ tended for use when carrying out the method according to the present invention consists in a manner known in prin ⁇ ciple of a base material 1 in sheet or web form, and a number of raised portions or projections 2, in the example shown being in the shape of truncated square pyramids, placed in a pattern of rows in ⁇ tersecting each other at right angles on the base material 1.
  • the starting material 1,2 is in a manner known per se produced from fiber material, e.g. by depositing fibers from a "soup" or pulp produced e.g. from vegetable fiber mass, especially wood pulp or paper pulp including recycled such, against a mould consisting of fine-mesh gauze, on the rear side of which a "negative" pressure is maintained to cause the fibers to be deposited by being filtered out on the mould. After this depositing step, the starting material is removed from the mould and dried until it becomes dry and rigid, thus presenting itself with roughly the same material properties as the well- known egg trays of the same material, and like these, it has roughly the same wall thickness at all points, i.e. also in the raised portions or projections 2.
  • the starting material shown in Figure 1 can be used as it is for packaging purposes, e.g. as a protective insert between a corrugated-paper box and an article packaged therein, provided that the article has the same shape as the box, but having smaller dimensions corres ⁇ ponding to the interspace to be filled by this starting material.
  • the present invention is, however, concerned with adapting the starting material shown in Figure 1 with a view to packaging articles that are not box-shaped, e.g. round, bottles, video cameras etc. , and this is achieved by, as show in Figures 2 and 3, modifying the shape of some of the raised portions or projections 2, so that these can support the packaged article in an appropriate manner.
  • certain raised portions or pro ⁇ jections 2a have been pressed down to a height far below their original half-height to form af dish-shaped top, while other projections 2b situated on opposite sides of the projections 2a are pressed down to form oppositely facing arched side surfaces lying on the same circular cylindrical surface as the arched top of the projections 2a.
  • projections 2c and 2d are partially pressed down to form composite surfaces, together with the pres- sed-down surface on the projections 2a and 2b forming a bed, in which a cylindrical article 3 can rest, cf. Fi ⁇ gures 4 and 5.
  • the article 3 may suit- ably be packaged in a corrugated-paper box 4, indicated in broken lines, by cutting-out two pieces of suitable size and extent from the base material 1 and placing the article 3 between these pieces inside the box 4.
  • Figures 6 and 7 show a lower press platen 5 and an upper press platen 6 as preferably used when carrying out the method according to the present invention.
  • the lower press platen 5 may e.g. be a rigid plate of steel or aluminium, in which uniform holes 7 are bored in a pattern corresponding to the pattern, in which the projections 2 and 2b-2d are placed, while in the upper press platen 6, consisting e.g. of the same material as the lower press platen 5, holes 8 with the same shape and in the same distribution as the holes 7 in the lower press platen 5 have likewise been bored.
  • a number of lower press blocks 9 and 9a-9d are secured to the lower press platen 5, of which press blocks 9a-9d are shaped corresponding to the desired shape of the projec ⁇ tions 2a-2d respectively, while lower press blocks 9 are solely placed in a number - which may equal zero - cor ⁇ responding to what is needed for guiding the starting material 1,2 in the press (not shown) concerned.
  • the upper press platen 6 is provided with one or a number of upper press blocks, in the example shown solely one single upper press block 10, the shape of which corresponds to the shape of that part of the cylin- drical article 3 to be supported by the projections 2a- 2d. All the press blocks are secured to the press platens concerned by means of screws 11.
  • the lower press blocks may be provided with pressing-surface pads 12 of rubber. This reduces the risk of parts of the projections being pressed being torn to pieces during the pressing-down operation, and at the same time any minor variations in the wall thickness in the projections, which otherwise could cause problems, especially when simultaneously pressing a number of packaging elements from one single piece of starting material, are accommodated.
  • the pressing operation is quite simply carried out by placing a starting material 1,2 as shown in Figure 2 on top of the lower press platen 5 shown in Figure 6 in such a manner that the projections 2 are moved down- wardly onto the lower press blocks 9 and 9a-9d. Then, the upper press platen 6 is moved downwardly towards the lower press platen 5, by which the upper press block 10 in cooperation with the lower press blocks 9a-9d ' shape the projections concerned so as to form the desired pro- jections 2a-2d.
  • the pressing operation may possibly be carried out whilst providing suitable humidification and heating, e.g.
  • the pressing operation may also be carried out without using lower press blocks, primarily in those cases, in which the whole top part of the projections concerned is to be pressed down. If the angle 13 shown in Figure 3 between the oppositely facing side walls in the projections 2 lies within the interval 20-40°, experience has shown that such a pressing-down operation causes the formation of "accordeon pleats" in the upper part of the projection without substantially reducing its strength. Tests having been carried out until now have indicated that this angle should preferably be approximately 30°.
  • the example of a starting material for use when carrying out the method according to the present invention as shown in Figure 1 has a number of raised portions or projections 2 having the shape of truncated pyramids and being placed in a pattern of rows at right angles to each other, but the present invention may also be carried out using starting material, in which the raised portions or projections are differently shaped and/or placed in other patterns than here shown and described.
  • the projections are at least uniform and placed in a regular pattern, e.g. like the one shown or in the form of a "honeycomb pattern", as this makes it considerably easier to adapt the press tools shown in Figures 6 and 7 to producing packaging elements of dif ⁇ ferent shape.

Abstract

Eléments d'emballage destinés à supporter des articles conditionnés (3) ayant des surfaces non planes à l'intérieur de leur conditionnement (4). On réalise ces éléments dans un matériau de départ présentant une série de parties en relief ou projections (2), en postformant certaines (2a, 2b) des parties en relief ou projections en les pressant de telle manière qu'elles contribueront à soutenir l'article (3). Selon ce procédé, il est possible d'employer le même matériau de départ (1, 2) pour réaliser des éléments d'emballage d'articles de formes diverses. L'équipement, constitué d'appareils de pressage (non représentés), peut être constitué de blocs de pressage supérieur et inférieur, fixés à une platine supérieure et à une platine inférieure de manière à pouvoir être enlevés et remplacés par des blocs de pressage adaptés aux articles à conditionner.
