Abstract

Box of the so-called "single-cup" type, obtained from a blank of semi-rigid material, such as cardboard, by cutting, folding and gluing the edges of this blank so as to create two volumes fitting together the one inside the other, delimited by three fixed partitions extending over three edges of a back panel, and joined by a common panel whose transverse edges, starting from the fourth edge of each back panel, allow the first to be folded volume over the second, said common panel constituting, in the folded state the fourth partition of the first volume, characterized in that, in the interior of said box, is disposed an auxiliary blank of semi-rigid material, said auxiliary blank comprising a first panel immobilized on the bottom of the first volume, and being extended by a succession of panels whose folding successively creates a fourth fixed partition for the first volume, a lining on said common panel and a last panel inserting freely against the back of the bottom of the second volume, the front edge of the latter panel, resting on the corresponding partition of the second volume, ensuring the immobilization in place of this auxiliary blank.

Description

The present invention relates to an improvement to boxes of the type

  called "single-bowl" obtained, in a conventional manner, by cutting a single blank, generally made of cardboard, then folding and gluing the edges of this blank, so as to create two volumes each delimited by three fixed partitions and joined by a common panel, the transverse edges of which allow the first volume to be folded over the second, which it fits, said panel thus folded constituting the

  fourth partition of the first volume.

  Although these boxes are very widespread, and for many uses, they all have a common drawback which, in certain applications, can be annoying, namely that the fourth partition of the first volume, that is to say from the bottom of the box, is only in place to delimit this box and enclose its contents only when the second volume, that is to say the lid, is completely folded down by fitting the first volume: when the lid is opened, the bottom of the box is only delimited by three partitions and its contents can escape from it by the fourth side In the case where this content consists of small free objects, as for example when these boxes are used in jewelry, it can be annoying to see the object

  escape from the box when you open it.

  An additional disadvantage of this type of box is inherent in its design: as the two volumes are joined by a couple of edges forming hinges, the tensions remaining in the material during folding tend, when the cover is closed, to cause lifting of this cover If even this opening is only partial, it is annoying because it is unsightly and contains the

  risk of untimely complete opening.

  Finally, in most uses of these boxes, it is usual to place on the back of the cover, a lining bearing the identification of the origin of the product contained in the box, for example, a personalization plate This additional operation has a affect the cost price of the box, which is a

  third drawback of it.

  The invention eliminates these three drawbacks thanks to a simple and

inexpensive from this type of box.

  The arrangement according to the invention consists in having in the set of two volumes forming the box, single-bowl, an auxiliary cardboard blank comprising a first panel coming to rest on the bottom and on the three fixed and extending partitions by successive panels whose folding successively creates a fourth fixed partition for the first volume, a doubling on the panel joining the first volume to the second and a last panel coming freely

  Insert and stop against the back of the second volume.

  Preferably, according to the invention, the means for immobilizing at least one panel consist of lugs which are inserted into corresponding slots in the corners of the bottom of the box cover. This simple blocking of the corners of a panel l 'immobilizes fully against the corresponding inner surface of the box, up to the area forming the fourth partition for the first volume, which ensures the immobilization of this fourth partition, which therefore eliminates the first drawback mentioned above. According to another characteristic of the invention, the upper outer corners of the first volume, that is to say of the box, also have tabs, formed either on the original blank, or on the auxiliary blank, and coming also fit into the slots at the corners of the cover, preferably at the same time as the tabs of the free panel above This fitting guarantees the immobilization of the cover in the closed position, which eliminates the second

disadvantage recalled above.

  According to yet another characteristic of the invention, the visible face of the free panel receives, before installation of the auxiliary blank, the indications making it possible to personalize the product contained in the box, that is to say generally the name of the dealer , a mark or the like, by simple printing on the flat blank The operation is therefore much simpler, quick and inexpensive than the establishment, then the installation of plates after the

  manufacturing the boxes The third drawback mentioned above is therefore eliminated.

  Other characteristics and advantages of the invention will become apparent during the

  description below of an exemplary embodiment, illustrated in the attached drawing on

  which: Figure 1 is a schematic perspective view of a first embodiment

  of the box according to the invention, in the ajar position.

  Figure 2 is a vertical cross section of the same box in the state

completely open.

  Figure 3 is a vertical cross section of the same box, in the state

completely closed.

  Figure 4 is a view similar to Figure 2 of a second embodiment

of the invention.

  Figure 5 is a flat view of the blank from which is made the mono- box

  mono-bowl, showing the shape of the notches and the clipping pins.

  Figure 6 is a flat view of another embodiment of an auxiliary blank clipable in the box of Figure 5 with a "parquet" insertable into the

"bottom" side of the box.

  And Figure 7 is a section similar to Figures 2 and 4 of the box variant

  obtained with the plan of figure 6.

  If one refers first to Figures 1, 2 and 3 which illustrate a first embodiment of the invention, the general reference F designates a cardboard blank which, folded and glued, constitutes the "single bowl" box of departure of the well known type and comprising a first volume V 1, forming the bottom of the box proper, consisting of a bottom 1 and three fixed partitions 2, 3, 4 and a second volume V 2 forming the cover, also comprising a base 5 and three fixed partitions 6, 7, 8, the volumes V 1, V 2 being joined by a transverse panel 9 which can be folded along two grooved edges 10, 11 to allow the cover V 2

  to come and fit around the bottom V 1 as shown in Figure 3 -

  As explained above, the volume V 1 then lacks a fourth partition, at the level of the groove 11, to be completely closed, otherwise its content may

  escape from it by the corresponding face.

  Similarly, by their natural elasticity, the folds of the blank F around the edges 10, 11 even grooved will tend to return to their original shape, which will cause the spontaneous opening of the cover V 2 Finally, it was customary to fix on the front of the bottom 5 of the cover V 2 a plate or pad, produced separately and bearing the mark and

  the identification of the merchant using the box.

  To avoid these various drawbacks, the invention consists in associating with the above box an auxiliary blank F 'also made of cardboard and comprising, on the one hand, a first panel 12 which, in this first embodiment, is stuck on the bottom 1 and the three partitions 2, 3, 4 of volume V; and, on the other hand, successive non-glued panels 13, 14, 15, 16, the folding of which successively creates a fourth fixed partition (13, 14) at the height of the fold 11 for the volume V 1, a doubling (15) for the transverse panel 9 and a last panel 16 coming freely to be inserted against the

bottom 5 of volume V 2.

  Normally, the simple abutment of the terminal transverse edge 17 of the panel 16 against the angle of the bottom 5 and of the partition 6 may be sufficient to immobilize this panel 16, and at the same time, the other free panels 13, 14, 15 However , preferably, according to the invention, the panel 16 comprises at the outer corners, lugs or lugs 18 coming to be inserted in corresponding notches 19 from the bottom 5 These notches are not visible from the outside, because they are made in only a fraction of the thickness of the bottom 5 (and / or) of the partition 6 Thanks to this system of lugs 18 / notches 19, the immobilization of the free part of the blank

It is guaranteed.

  Correspondingly, the corners of the box V 1 have at their upper part tabs 20 which are inserted into the notches 19, which

  immobilizes the cover V 2 in the closed position.

  Finally, it is clear that one can easily print on the visible face of the panel 16 all the indications or information on the merchant who will use these boxes to distribute these products, which eliminates the need to make the pads or pads that we had previously to stick on the bottom 5 according to

an additional operation.

  As shown, the bottom 5 can also be slightly curved, to better hold the product in place in the closed box, instead of said pads. If we now refer to FIGS. 4, 5 and 6, there are illustrated other embodiments of the invention, preferred in that the auxiliary plane does not include

  no portion glued, but is fully clipped into the single-bowl box.

  In these figures, the same reference numerals designate elements

identical or similar.

  Thus, in FIG. 4, similar to FIG. 2, we find the constituent elements of the single-bowl box, namely the volume or bottom V 1 consisting of a bottom 1 and three fixed partitions 2, 3 and 4 , and a volume or cover V 2 consisting of a bottom 5 and three fixed partitions 6, 7 and 8, the volumes VI and V 2 being joined by a

  panel 9, articulated along two grooved edges 10 and 11.

  However, in this embodiment, the auxiliary blank F 'is not glued by its bottom 12 to the bottom 1 of the volume V 1 but immobilized by clipping the end 32 of a fold 30, 31 similar to the fold 13, 14 in notches 33 at the bottom 1, the shape of these notches 33 not appearing in FIG. 4, but appearing under the

  reference "Detail A" in figure 5.

  We also find in this figure 5 all the elements of the mono- box

  mono-bowl, but unfolded completely flat The "Detail A" represents each of the clipping notches 33 of the auxiliary blank F ', while the "Detail B"

  represents the shape of the legs or lugs designated by 18 in the description of

Figures 1 to 3.

  Finally, Figures 6 and 7 show a variant form of the auxiliary blank F 'by which, instead of a fourth fixed partition for the bottom of the box, is created in this bottom a raised volume or "parquet", according the term used by jewelers. In this latter variant, the single-bowl box being unchanged and obtained from the blank of FIG. 5, the auxiliary blank of FIG. 6 comprises a bottom 34 from which four panels 35, 36, 37, 38 are folded down. having the same height, of the order of half the height of the edges 2, 3, 4 of the bottom of the box. The bottom 34 is therefore raised above the bottom 1 by the height of these panels 35 38, and constitutes what is customary to call a "parquet", on which

  is presented and highlighted the object contained in the box.

  The auxiliary blank of FIG. 6 also includes the same panels 15 and

  16 being placed on the panels 9 and 5 of the single-bowl box.

  The immobilization of this "parquet" is also ensured by the legs 18,

  locking in the notches 33 of the box.

  This variant falls within the scope of the present invention, although the blank of FIG. 6 does not include an element creating a fourth fixed partition for the bottom V 1, insofar as it is customary, in the case of '' such a floor, to slide part of the object into a slot in the floor 34, and the assembly is still immobilized

by clipping.

  Of course, instead of cardboard, it is possible to use for the production of the boxes according to the invention any semi-rigid material which can be bonded or welded such as polyethylene PVC and the like. The auxiliary blank may moreover be made of a material

  different from that of the blank constituting the box proper.
