Definitions
- This invention generally relates to punched cardboard boxes, of the type which is delivered to the customers in a flattened condition and having a pair of opposite walls already formed and a pair of opposite walls to be formed, these walls being attached to each other by means of bellows tabs permitting the assembly of the box by exerting a force on the opposite walls to be formed and, more particularly, to an improved box of this type.
- wall both simple walls and cavity walls (hollow walls) are intended.
- the boxes of this type are delivered in a flattened condition in order to occupy a very small space during the transport. Since they have a pair of opposite walls already formed, it is necessary to form only the other pair of opposite walls to obtain the box in the use condition, thereby offering the further advantage of requiring a lower number of assembly operations.
- a single cardboard blanc is used and by starting therefrom a pair of opposite walls are first formed which then are folded in a flattened condition to be delivered to the customers.
- the pair of already formed walls are connected to the other pair of opposite walls to be formed by means of suitable bellows tabs which have the function to produce the erection of the formed opposite walls when the opposite walls to be formed are mounted in order to obtain the use condition of the box.
- the assembly of the box can be carried out by hand or by means of machines suitable for this operation, the latter solution being of course preferred because of the high assembly speed which can be obtained thereby.
- the walls to be formed are possibly provided with means for locking them in the assembled condition. This feature offers the great advantage of permitting the assembly of the box by means of machines.
- the bellows tabs ca cause glueing disadvantages because the box provided with the cavity sidewalls preformed in a flattened condition has different thicknesses.
- the present invention aims at obviating these and other disadvantages by providing a box having a pair of sidewalls already formed and a pair of sidewalls to be formed attached to each other by means of bellow tabs, which is improved from this standpoint.
- the punched cardboard box of the type delivered to the customers in a flattened condition and having a pair of opposite walls already formed and a pair of opposite walls to be formed connected to the formed walls by means of bellows tabs foldable along an oblique folding line and having the function to produce the erection of the formed walls during the box assembly for obtaining the use configuration of the box is characterized in that:
- Fig. 1 shows a blanc F intended to form a box having cavity sidewalls, and only for the portion which is of interest for the present invention.
- This blanc F has a bottom 10 to which the portion intended to form the cavity sidewalls A already formed and the portions intended to form the cavity sidewalls B to be formed are attached.
- the portions forming the cavity walls A already formed include the strips 14 for forming the outer vertical sides of said cavity walls A, the strips 15 for forming the upper sides thereof, the strips 16 for forming the inner vertical sides thereof and the end strips 17 intended to bear on the box bottom 10 and to be glued thereto in an assembled condition. Extending from the bottom 10 and through folding lines 18 are also the portions forming the cavity walls B to be formed.
- Each of such portions includes a strip 19 for forming the outer vertical side of said cavity walls B and extending, through the folding line 20, in a strip 21 having beveled ends and intended to form the upper side of the cavity walls B.
- This strip 21 extends through a folding line 22 in a strip 23 having at each of its ends rounded projections 24 and 25 forming locking means for locking in position by snap action the cavity walls B and intended to form the inner vertical sides thereof.
- the strip 27 intended to bear against the box bottom 10 extends. From the ends of the strips 15 ears 28 outwardly project, which are intended to enter the cavity walls B to be formed in order to facilitate the assembly thereof.
- the strips 16 forming the inner vertical sides of the cavity walls A already formed have at their ends a pair of slots 11 for making this wall elastic and for cooperating with the projections 24,25 of the inner vertical side of the cavity walls B to be formed in order to lock them by snap action in an assembled condition, as well as to prevent vertical movements thereof.
- bellows tabs 29 which are substantially square or rectangular in shape and which are foldable along an oblique folding line 12, which, in this case, is interrupted by a slot 13 extending parallel to the folding lines 18-20.
- This slot 13 terminates in an arcuate segment S the purpose of which is to resolve the tearing force acting on the bellows tabs 29 during the box assembly in its components and therefore to reduce the tearing danger thereof.
- a tongue 30 Projecting from each of the bellows tabs 29 in the direction of the cavity walls B to be formed is a tongue 30 the purpose of which is to obviate the above mentioned disadvantages.
- the box as already said, is delivered to the customers with the formed cavity walls A inwardly folded so as to obtain a flattened condition of the box.
- the strips 17 are therefore glued to the box bottom 10 and the bellows tabs 29 are glued to the inner surface of the strips 19 of the cavity walls B which are to be assembled by hand or by suitable machines in order to obtain a use condition thereof.
- Fig. 5 shows a blanc F intended to form a box having simple sidewalls, limited to the portion which is of interest for the present invention.
- This blanc has a bottom 10 to which the portions intended to form the walls A already formed and the portions intended to form the walls B to be formed are attached.
- Each of the portions forming the walls A already formed includes the strip 14 extending through the folding line 31 in a strip 15 and forming the wall A once they have been folded and glued one against the other. Extending from the bottom 10, through folding lines are also the portions forming the walls B to be formed.
- Each of such portions includes three strips 19,21,23.
- the strip 19 extends through the folding line 20 in the strip 21 which in turn extends through the folding line 22 in the strip 23.
- the strip 21 has at each of its ends a triangular projection 24 forming the locking means of the walls B to be formed when the strip 21 is folded against the strip 19 and the strip 23 is folded so as to bear against the bottom surface. These projections abut the bevel 25 provided in the strips 15 of the walls A.
- the strips 14 of the walls A already formed and the strips 19 of the walls B to be formed are connected to each other by the bellows tabs 29 which are substantially square or rectangular in shape and foldable along the oblique folding line 12, which is interrupted by a slot 13' extending parallel to the folding lines 18-20.
- This slot 13' can be the same as that of the slot 13 of the box described in connection with Figs. 1-4, but in this case a modification thereof is described which is valid also for the embodiment of Figs 1-4.
- This slot 13' is triangular in shape with rounded apex S and the roundnes of this apex S is intended to resolve the tearing force acting on the bellows tabs in its components and therefore to minimize the tearing danger of the bellows tabs 29 during the box assembly.
- a tongue 30 Projecting from each of the bellows tabs 29 in the direction of the walls B to be formed is a tongue 30 the purpose of which is to obviate the above mentioned disadvantages.
- the box as already said, is delivered to the customers with the formed walls A folded inwardly in order to obtain a flattened condition of the box.
- the strips 14 and 15 are therefore glued to each other for forming the reinforced walls A of the box and the bellows tabs 29 are glued by hand or by suitable machines to the inner surface of the strips 19 of the walls B when the box is to be put in use.
- the bellows tabs 29 according to the invention and also the projecting tongues 30 permit the above mentioned drawbacks to be avoided.
- what is glued to the inner surface of the strips 19 of the walls B to be formed is no longer the bellows tab as in the preceding embodiment, but the projecting tongue 30. It is folded inwardly on itself as can be seen from Figs. 2,3 and 6,7 respectively and glued against the inner surface of strip 19 forming the walls B to be formed.
- the walls A already formed are erected by the action exerted by the bellows tabs 29 during the assembly of the walls B to be formed.
- the bellows tabs 29 are folded along the folding line 12 by compelling the walls A already formed to assume their erected position. Since the tongues 30 are already glued, this action is facilitated by the slots 13, 13' respectively, which open.
- the characteristic shape of the slots 13 and 13' minimizes the tearing problem which occurs particularly during the machine assembly of the box.
- the tearing force acting on the bellows tab is resolved in its components by the arcuate segment S of the slot 13 and by the rounded apex S of the slot 13'. The resolution of the tearing force in its components permits the tearing danger of the bellows tab to be reduced.
- this fold causes the box in a flattened condition which is treated in the glueing machines for forming the walls already formed, to have a uniform thickness along all the sides of the walls already formed and therefore there are no longer problems of glueing of the bellows tabs.
