Description

REMOVABLE PLATE FOR PACKAGE PACKAGE, APPLICATION TO THE

REALIZING A PALLET CASE

  The subject of the invention is a removable pad for a packing case, in particular made of cardboard, comprising four vertical walls extended to their

  upper and lower edges by flaps forming the faces of

  above and below when folded These crates are still called

American boxes.

  It also aims to apply this plot to the realization of a

Integrated pallet box.

  The development of cardboard pallets has necessitated the concomitant development of the pads supporting them. Moreover, in order to produce these pallets, in view of the relatively high cost of the carton, it is preferable to use the least possible of this material while ensuring sufficient rigidity. The object of the invention is to propose a new corner pad ensuring

  a rigid plot-to-crate connection by means of an original locking system

  ginal This allows for a simplified pallet box.

  According to the invention, the removable pad is characterized in that it is formed of a rigid sheet divided into two parts by a fold line (called the first fold line) orthogonal to the longitudinal direction of the sheet.

  A first part is provided with an opening in which comes

  securing a foot fixed by suitable fixing means, while the second part is provided with at least one lateral band articulated thereto by a second fold line perpendicular to the first fold line, the lateral edge of this band , located on the side of the part provided with an opening, being perpendicular to the second line of

  folding relative to the longitudinal direction of the sheet.

  Preferably, the second fold line is located at the extreme point

of the first fold line.

  Preferably, the lateral edge perpendicular to the second fold line is located substantially on the same line as the first fold line. The two preferred variants taken in combination allow a calibration

optimum of the plot.

  By fold line is meant an articulation of the sheet This implies that it may be rounded or even consist of several

  creases in the case of a thick sheet.

  Preferably, the second part is provided with two symmetrical lateral bands, which makes it possible to use a single form of stud for

  realize the pallet crate as will be understood later.

  A rigid sheet may be formed for example of a sheet of cardboard

  corrugated or plastic sheet.

  The fixing means of the pad to the sheet are well known to man

  and the invention is not limited to a particular method of attachment

  link. For indication, mention may be made of the methods of attachment described in the following patents

  The invention will be better understood with reference to an embodiment

  particular represented by the appended drawings.

  FIG. 1 is a plan view of an unfolded removable stud, the foot

being below the leaf.

  FIG. 2 is a sectional view of the same stud according to the sec-

AA '.

  Figure 3 is a perspective view of the same pad but with partial folding of the two parts constituting the sheet. FIG. 4 is a view of an inverted packaging carton, to make the drawing clearer, and in which one of the flaps in

  open position is provided with a removable support.

  FIG. 5 is a view of the same carton but with the flap closed

equipped with removable support.

  According to FIGS. 1, 2, 3 a rigid corrugated cardboard sheet is constituted

  of a part (1) having the shape of a square of side 1 L 1 separated from a second part (2) by a fold line (3) merging with

one of the sides of the part (1).

  However, the square shape for part (1) is not at all

  sand and it is quite possible that the 3 sides delimiting the part (1), except the fold line, are a rounded shaped line

  semicircle or half ellipse for example, or even in some

  conch. The portion (1) is provided with a circular central opening (4) on the edge of which is a non-figured cutout for engaging a conical shaped plastic foot (5), the widest base of this foot being located at the opening (4) and the base

  narrower being intended to come into contact with the ground.

  As exactly described in French Patent No. 2123455, the plastic foot comprises at the edge of the widest base a flange (8) and a little below at a distance substantially equal to the thickness of the sheet of cardboard a second flange (9) parallel to the first and provided with a notch (10) for inserting the foot by

a rotational movement.

  -Part (2) is of rectangular shape It is defined by the length L 2 and its width 12, parallel to the fold line (3) and greater than the length of this fold line The portion (2) furthermore a longitudinal axis passing through the middle of the fold line (3) In addition the four corners are rounded to facilitate its use as will be understood later Instead of rounded corners it is

  possible also that the side edges (15) are slightly

  Here we see from the previous description that part (2)

  has two lateral strips (6 a) and (6 b) of equal dimensions These lateral parts are hinged by means of two fold lines (7 a)

  and (7b) perpendicular to the fold line (3) and located at the

  respective trenches of this fold line (3).

  Advantageously, the part (2) comprises an opening (t 6) which,

  when the part (2) is folded, is superimposed on the part (1).

  This allows to store the pads with a saving of space.

  According to Figures (4) and (5), an erected carton comprises four vertical walls (11). These vertical walls are extended beyond the lower edges by four flaps forming two pairs of

opposite flaps (12a and 12b).

  In our case the two opposite flaps each forming a half-surface

  from the bottom, are rectangular in shape, the short sides or sides

  raux (13) constituting the width of the flap.

  The removable supports are inserted in the following manner A pair of opposite flaps (12b) is folded horizontally to form a first bottom With a flap (12a) open, a side portion (6a) of the removable support is inserted in the gap between the side edge of a flap (12b) and the lower edge of one of the corresponding vertical walls so that the

  folding (7 a) at this edge.

  vible is then folded so as to pinch the flap (12 a), the line of

  folding (3) positioned against the side edge (13) of the flap.

  This flap is also provided on its other lateral side with another support.

  removable port The same operation is performed on the opposite flap The pair of flaps is then folded to form the bottom with the four feet The assembly is then circled so as to block the flaps (12 a) If we want to avoid the strapping, it is possible to glue the

  flaps (12 a) or staple them with flaps (12 b).

  It is also possible to mold the stud in one piece In this case the parts (1) and (2) are folded from the beginning so, preferably, to exert a certain pinch on the flap when the stud

removable is set up.
