FR2811293A1 - Carton box has open sidewall closed by curtain panel attached to lid, for transport and retail presentation of commercial goods - Google Patents

Abstract

A carton box (10) is used for the transport and retail presentation of otherwise small loose products. The box has a rectangular base (12) and four sidewalls (16,18,20). The front panel (14) has a U-shaped cutout (24) revealing the box contents on inspection. The box further has a rectangular lid closure with a hanging panel which is inserted inside the box base front panel during transport.

Description

1 2811293

  Packaging provided with a side window which can be closed during

transportation.

  The present invention relates to a box-shaped packaging which has on one of its lateral faces a window revealing the packaged products and through which the customers

can use.

  In large retail outlets, the current trend is to use packaging which can be easily transformed into displays. By means of this transformation, the products are displayed for sale in the same packaging where they are packed without

  have to transfer them to the store shelves.

  A packaging of this type is known which comprises on at least one of the side walls a portion which can be detached by tearing along a line of low resistance. At the time of sale, the detachable portion is cut to create a window through which the products can be removed. For this, one can either tear off said portion along the line of low resistance, or burst it by pressure with the fingers, or even cut it with a cutter or any other sharp instrument. These operations must be carried out with care if the tear is to take place exactly along the line of weak resistance. But this is not always possible and it often happens that the detachable portion is torn off outside the line of low resistance, which harms the aesthetics of the body. Even in the case where said portion detaches exactly along the line of low resistance, there will always remain on the edge of the window many small points resulting from the rupture of the bridges by which the detachable portion was attached to the

remaining from the body wall.

  The need therefore arises for a packaging provided on one of its side walls with a window with a clean edge, which is normally closed during transport and the opening of which is very

  quickly, without the use of a cutter and without tearing.

  To obtain this result, the invention provides a packaging comprising: a box provided with a bottom and side walls and open at its upper part, one of the walls of the box or front wall having a notch which internally defines a window,

2 2811293

  - And a cover comprising a bottom wall of the same surface as the bottom of the body, peripheral lateral flanges perpendicular to the bottom wall, a connecting strip articulated by a first fold line along the end of the front flange of the cap, and being folded against the inner face of said front edge, and a closing plate articulated on said connecting strip according to a second folding line parallel to the first folding line, said closing plate having a surface slightly smaller than that of said front wall of the body and being

  can be slid against the inside of the front wall.

  During transport, the window is closed and retains the products.

  At the distributor, all of the cap and the blanking plate are removed, which allows access to the products through the window and

  the upper opening of the box.

  An embodiment of the invention will now be described by way of example, with reference to the accompanying drawings in which: FIG. 1 is a perspective view of an embodiment of

the box according to the invention.

  Figure 2 is a plan view of a corrugated cardboard blank for making the cap; Figures 3 to 5 are perspective views illustrating three successive phases of the closing of the box with the cover and the shutter of the window with the shutter plate; and

  FIG. 6 is a sectional view along the line VI - VI of FIG. 5.

  The invention will be described in the case of an American half-case made of corrugated cardboard, as illustrated in FIG. 1, but it is not

limited to this type of box.

  The box 10 comprises a rectangular bottom 12, a front side wall 14, a rear wall 16 and two side walls 18, 20 and it is open at its upper part. The front wall 14 has a deep U-shaped notch 22 which internally defines a window 24 giving

  wide access to the interior of the body.

  FIG. 2 represents a blank 26 of corrugated cardboard comprising a first portion from which the cap itself is formed. This portion comprises a rectangular bottom 28 of surface substantially equal to that of the bottom of the box and four flaps 30, 32, 34, 36 articulated on the bottom by fold lines 38, 40, 42, 44. The

3 2811293

  front and rear flaps 30, 32 are provided at their ends with lugs by which they can be fixed to flaps 34, 36 to form

  a peripheral rim around the bottom 28.

  On the front flap 30 is articulated, by a folding line 46 parallel to the transverse fold lines 38, 40, a rectangular connecting strip 48 centered relative to said flap 30. Preferably, the connecting strip has a length L slightly shorter the width of the window, but this condition is not necessary. The connecting strip

  has a width l equal to the width of the front flap 30.

  On the connecting strip 48 is articulated by two drawdown lines 50, 52 close together and parallel to the first drawdown line 46, a rectangular closure plate 54 of surface substantially equal to the surface of the inner face of the front wall 14 from the cash register. The lateral edges of the cover plate are cut at their ends in a bevel to facilitate the introduction of the plate into

the box.

  The cap can be placed on the box, for example as illustrated in FIGS. 3 to 5. After the box has been filled at the producer with the products to be packaged, which may be bulk material or packaged products in packaging

  individual, we have the cap as shown in Figure 3,

  that is to say that its rear part is fitted on the rear corners of the body and the lower edge of the closure plate 54 is inserted between the

  internal face of the front wall 14 of the box and the products.

  The shutter plate is then pushed in in the direction of the arrow f in FIG. 3, while rotating the cover in the direction of the arrow F. The angle formed by the connecting strip 48 and the shutter plate 54 opens gradually, until it becomes substantially flat. A slight pivoting is then printed on the closure plate in the direction where it deviates slightly from the front wall 14 towards the interior of the box. The connecting strip then retracts towards the inside of the cap and is gradually applied against the inner face of the front flange 30, as illustrated by FIG. 4 and more clearly by FIG. 6. The thin strip of carton 56 between the fold lines 50 and 52 bears on the upper edge of the front wall 14. The box is then closed by the cover and the window

closed by the blanking plate.

  It goes without saying that the fitting of the cap and the obturating plate can be carried out differently. For example, the cap can be held horizontally above the opening of the box, while the sealing plate and the connecting strip are in the plane of the front wall 14 of the box. The lower edge of the sealing plate is then introduced between the front wall and the products. The entire cover is then lowered as a block until the obturator plate abuts against the bottom of the box. The entire cover and the connecting strip 48 are then pivoted around the double folding line 50, 52 until the connecting strip is applied to the outside face of the front wall 14 of the body and finally the cover is lowered to cover the upper edge

from the cash register.

  At the distributor, the opening of the box is done by lifting the cover. In this movement, the connecting strip unfolds and causes the closing plate to slide upwards and into the opening

from window 24.

  The window was thus opened with a simple and rapid gesture, not requiring the use of a cutter. The edge of the window is sharp

  since it was cut during the manufacture of the blank.

  According to an alternative embodiment of the invention, the wall 14 of the box may include a pre-cut line 22 in U defining internally a plate which is attached to the rest of the wall by zones of low resistance, said plate being able to be torn according to the pre-cut line to form the window. We will use with this

  conditioning a cap as described above.
