Definitions

  • the present invention relates to a foldable container.
  • the invention refers to a container having a rectangular base, obtained starting from rigid or semirigid materials, said materials being characterized by a certain elasticity and described in more detail in the following description of the invention.
  • Said container is characterized by a specific combination of foldings and cuts, realized on some of said flat surfaces so that, when empty and folded, said container takes a very reduced dimension.
  • the container according to the invention is obtained from materials having a given thickness and characterized a first a second face spaced by a gap containing a stiffening structure, as for instance a lamellar or a honeycomb structure.
  • a stiffening structure as for instance a lamellar or a honeycomb structure.
  • Such structures can be similar to those abovementioned for the corrugated board or polypropylene.
  • punched folding line a folding line is meant, obtained preferably by punching, traced on the surface of the container. A folding of said surface is made along this line, the folding being such to produce a rising of the surface or, alternatively, a lowering thereof, with respect to the plane containing the same surface.
  • the punched folding lines will be indicated with broken lines: those producing a rising of the surface will be indicated with dash lines, those producing a lowering will be indicated with dot-dash lines.
  • Fig. 1 schematically shows a perspective view of a first embodiment of a substantially parallelepiped container with a rectangular base according to the invention.
  • Fig. 2 is a top view of the container of Fig. 1.
  • Fig. 3 is a bottom view of the container of Fig. 1.
  • Fig. 4 is a schematic perspective view of a detail of the container of Fig. 1.
  • Fig. 5 is a view of the planar development of the container of Fig. 1.
  • Fig. 6 is a top perspective view of the container of Fig. 1, partially folded according to the invention.
  • Fig. 7 is a bottom perspective view of the container of Fig. 1, partially folded according to the invention.
  • Fig. 8 is a top perspective view of the container of Fig. 1, almost partially folded.
  • Fig. 9 is a schematic perspective view of a second embodiment of a rectangular base, substantially parallelepiped, open container according to the invention.
  • container (A) has an open parallelepiped shape with base (1) and lateral walls (2) and (3). Both punched folding lines and cut lines are present on container (A).
  • two cut lines (4) are on the base (1) and have a semicircular shape and such a lenght to facilitate opening and closing of the container. Any of such cut lines could be substituted by two converging substantially rectilinear lines having origin in (5).
  • the thickness of the container material is indicated with P.
  • the material is characterized by a first (7) and second (7') wall with an inteposed stiffening fin structure (6), in this case consisting in a sort of ribbing transversal to the punching lines.
  • the punched folding lines are indicated, as aboventioned, with broken line.
  • the punched folding lines essential for the present invention are the following.
  • To said lines (8) other (10) are associated, placed corresponding to the midline of lateral walls (3), corresponding lateral walls (2) being not provided with folding lines.
  • Other folding lines (11) are placed on base (1), parallel to each other and to the larger sides of base (1).
  • Said folding lines (11) originate on lines (8) and (4), and preferably, as in the embodiment of the figures, when folding lines (11) originate on folding lines (8), or at the intersection of line (8) with cut line (4), at the originating point an opening (5) or (9) is made, preferably as circular hole.
  • Such openings (5) and (9) facilitate opening and closing the container (A).
  • the number of folding lines (11) is not defined, preferably it is three or more, more preferably it is odd.
  • the so placed folding lines (11) facilitate the folding of the container (A) according to the invention, in that they in somewhat enhance the elasticity of the material.
  • folding lines (11'), parallel to each other, and also parallel to (11), and placed on base (1), cooperate to folding the container (A). They originate on the open zone (15) and end on cut line (4). As can be seen, they produce a folding direction opposite to the one of corresponding folding lines (11). Also the number of lines (11') does not limit present invention and it is function of the type of material used and of the necessity of folding. However such lines (11') are preferably even in number, and more preferably four.
  • folding lines associated to punched folding lines (8, 10 11, 11') and to cut lines (4), which help folding of container (A) according to the invention.
  • Such folding lines coincide with larger and lesser sides of base (1), they are indicated as (2') and (3') respectively and have the function of generating the parallelepiped container (A).
  • Still other folding lines, better seen in Fig. 4, are indicated with (12, 13, 14), they are parallel to each other and placed to join lateral walls (2) and (3) at the four corners of the lateral surface of the container (A). In this case they are three in that, due to the thickness P of container (A), with a lesser number it would not be easy to fold the container; anyhow such lines could also be present in a lesser or higher number.
  • lines (12) (13) and (14) do not necessarely have to be equally spaced.
  • container (A) has zones or openings (5, 9, 15, 16) which can have any form, as it simply means that some material was eliminated to facilitate folding of container, which has a thickness P.
  • Zones (16) are advantageously placed at the joining apexes between base (1) and lateral walls (2) and (3).
  • Zones (15) are advantageously placed between lines (10) and (11') and preferably have a substantially double T shape.
  • Zones (5) and (9), preferably in form of circular hole, are advantageously placed along lines (8), zones (5) being at the intersection between line (8) and line (4).
  • Figs. 1-4 has the planar development shown in Fig. 5.
  • the containers according to present invention are preferably obtained by shearing starting from a planar surface which, after this tis step, will have, for example, the planar development of Fig. 5.
  • lateral walls (3) of container (A) end with extensions (17) which can have any form, in that their sole function, in the assembling step, is to be folded and glued or otherwise strongly connected to the lateral wall (2) in order to obtain the container (A) in its final form.
  • the extensions (17) can be alternatively fixed on lateral walls (3).
  • zones (16) are shaped, and lines (12, 13, 14) are spaced among them, considering the presence of said extensions (17).
  • the punching steps to obtain folding lines and cuts are preferably performed before the assembling of container (A) in form of a box.
  • FIG. 9 A second embodiment of the container according to the present invention is shown in Fig. 9, in which container (A) has a particular shaping of lip (18) and has holes (19) acting essentially as handles for the container itelf.
  • Figs. 6-8 show container (A) through different folding steps in sequence, with top and bottom views.
  • the combination of cutting and folding lines, obtained by punching is able to give a folding so that the central zone of base (1) of container (A) lifts and its lateral walls (2) approach to each other, while lateral walls (3) bend along relevant centreline.
  • the punching operation brings to a sort of quasi-elastic folding of the container, which can be collapsed and then easily brought back to it original box shape with a simple operation.
  • Materials advantageously utilizable to obtain the containers according to present invention are all those materials which have spaced first and second walls connected by stiffening structures and which can be punched, such as e.g. board and plastic sheets of different kinds.
