Description

The present invention relates to a blank for a cardboard box with lid according to the preamble of claim 1. Furthermore, it relates to a box which can be produced from the blank.

One type of cardboard boxes for packaging products consists of a bottom body with so-called hollow walls. These hollow walls are essentially hollow columns, usually of rectangular or square cross-section. The associated cover body has side walls which overlap in the closed state of the box outside of the hollow walls and optimally fit tightly against this, in order to complete the interior well against the environment.

A hollow wall packing is from the DE-9 003 665 known. It has a lid which, however, does not comprise the side walls of the bottom body, but is essentially a plate. It is designed as a separate part and is attached to the bottom body during the manufacture of the box.

• – Sie sind mehrteilig, wodurch die Herstellung der Schachtel aufwendiger ist als bei einem einteiligen Zuschnitt.
• – Der Deckel ist an einer Oberkante der Wände angelenkt, was eine Abweichung vom ästhetischen Eindruck einer zweiteiligen Schachtel ergibt, eine zum Öffnen neigende Federwirkung hervorrufen kann und an seitlichen Deckelwänden freie Enden ergibt, die tendenziell von den darunterliegenden Bodenseitenwänden abstehen.
• – Die Schachteln sind nur im fertiggestellten Zustand versendbar, woraus eine geringe Packungsdichte resultiert.

Known designs of blanks of such boxes show at least one of the following disadvantages:

• - They are multi-part, making the production of the box is more complicated than a one-piece blank.
• - The lid is hinged to an upper edge of the walls, which results in a deviation from the aesthetic impression of a two-piece box, can cause a tendency to open spring action and gives free ends on side cover walls, which tend to protrude from the underlying bottom side walls.
• - The boxes are shipped only in the finished state, resulting in a low packing density results.

An object of the present invention is therefore to provide a blank for a box with a bottom body and a lid body, wherein side walls of the lid body overlap with side walls of the bottom body in the closed state, and which is in one piece.

Such a blank is specified in claim 1. The further claims specify preferred embodiments, a box that can be produced therewith, and a blank that is preprocessed for rapid completion of the box.

• – Die Hohlseitenwände können geklebt und flachgelegt werden, so dass die Verpackung im flachen Zustand und damit platzsparend an den Konfektionierungsort gebracht werden kann. Dort wird sie aufgerichtet, gefüllt und verschlossen. In einer besonders vorteilhaften Ausführung ist bei diesem Aufrichten und Fertigstellen ein Kleben nicht mehr nötig.
• – Der Deckel wird durch Zurückfalten der Deckelbahn des Zuschnitts auf sich selbst hergestellt. Dadurch ist im flachen Zustand auch die Innenseite des Deckels wie auch die meisten Seitenwände durch einseitigen Druck zusammen mit den Außenflächen bedruckbar.

Further advantages of the blank according to the invention or the box produced therewith according to the further claims are:

• - The hollow side walls can be glued and laid flat, so that the package can be brought in the flat state and thus save space to the confection. There she is raised, filled and closed. In a particularly advantageous embodiment, gluing is no longer necessary in this erection and finishing.
• - The lid is made by folding back the cover sheet of the blank on itself. As a result, in the flat state, the inside of the lid as well as most of the side walls can be printed by one-sided printing together with the outer surfaces.

Further advantages, features and possible applications of the present invention will become apparent from the following description in conjunction with the embodiments illustrated in the drawings.

In the specification, claims, and drawings, the terms and associated reference numerals used in the list of reference numerals below are used. In the drawing:

1 a spatial representation of a box according to the invention in the open state, and

2 a one-piece blank according to the invention.

The box 1 includes a bottom body 3 and a lid body 5 by a hinge part 7 connected to each other. The soil body covers beside the actual soil 9 a front cavity wall 11 , a left cavity wall 13 , a right cavity wall 15 and a rear cavity wall 17 ,

The lid body 5 includes the cover plate 19 on which connect the side walls projecting downwards in the closed state, namely the front cover wall 21 , left lid wall 23 and right lid wall 25 , The rear lid wall 27 is part of the hinge part 7 , Between left cavity wall 13 and left lid wall 23 extends the left hinge wall 29 , and correspondingly between the right cavity wall 15 and right lid wall 25 the right hinge wall 30 ,

If the lid body according to arrow 32 moved to the box 1 close to form the hinge walls 29 . 30 Gusseted pleats, with the gusset tips as indicated by arrows 34 to move inwards. The lower back corners 36 the lid side walls 23 . 25 Thus, when closing to the rear lower corners 38 the bottom side walls 13 . 15 move, so that when closed Condition the lid sidewalls 21 . 23 . 25 and 27 at the bottom side walls 11 . 13 . 15 and 17 issue.

The gusseted hinge walls 29 . 30 In doing so, they exert a pull towards the box on the rear edges 38 the lid side walls 23 . 25 out, leaving the lid sidewalls 23 . 25 along the entire length close to the ground side walls 13 . 15 issue.

The floor-side slopes of the cut-outs in the gussets 29 . 30 are S-shaped, so that a pleasing transition between the lid side walls 23 . 25 and the bottom side walls 13 . 15 results. Besides, the tip is 28 the gusset cut executed as a result of the S-shape rounded, what the folding mechanism a queuing at the gusset 30 prevented.

The packaging 1 thus has a close to the bottom body in the closed state 3 surrounding lid body 5 on equivalent to the known box with separate, completely removable cover part.

Another advantage of the box 1 is that only the tabs 40 the bottom side walls 13 . 15 with the ground 9 glued while the other high-level parts are formed by folding and mating. In a preferred state of delivery, these bonds are carried out, but the side walls 13 . 15 laid flat outwards and the remaining parts of the blank in the flat position of the production.

An essential factor for the stability of the finished shaped box 1 is that on the one hand, the material of the box is sufficiently stiff to when folding the front and rear side walls of the floor 11 . 17 to obtain a sufficient rigidity and also restoring force. The precisely cut foot straps 42 . 44 the front or rear cavity wall 11 . 17 lie with their oblique side edges close to the corresponding side edges of the tabs 40 on, resulting in a self-locking.

2 shows the cut 50 from which the box 1 can be produced. Here are lines that do not belong to the contour, weakening lines or short incisions in a conventional manner. The lines of weakness serve primarily to specify defined folds during the production of the box. They can be designed as grooves, perforations, incisions or other types known per se.

Left and right at the bottom 9 close the parts of the side walls 13 . 15 on, namely outer wall 52 , Top surface 53 , Inner wall 54 and foot strap 40 , The same arrangement is also found on the front cavity wall of the floor. The outer walls 52 are over gusseted pleats 57 connected together when forming the front cavity wall 11 in the cavity wall 11 into work. For the production of the box 1 becomes section 54 the side walls 13 . 15 folded inwards and the foot straps 40 are glued to the floor. The kink occurs at the weakening line 59 so the horns 60 pointing to the ground. Be the side walls 13 . 15 set up, that's how the horns point 60 in the direction of the later front cavity wall 11 , The sections 52 . 53 and 54 the front cavity wall 11 are turned inwards around the horns, with the side locking tabs 61 into the cavity wall are bent approximately at right angles and thus under the horns 60 be pushed. The foot strap 42 comes in the erected state of the front cavity wall 11 between the foot straps 40 the side walls 13 . 15 to lie. In cooperation with the appropriately selected material, ie sufficiently stable cardboard, optionally coated on the surface with plastic, which provides a sufficient restoring force after folding, and the locking tabs 61 , the horns 60 and the abutting foot straps 40 . 42 results in a stable arrangement of the three side walls 11 . 13 . 15 where only the foot straps 40 glued to the ground.

To mention is still the section 64 from the front outer wall 52 , which in the folded state forms a slightly protruding tongue for opening the box.

• – obere Deckelfläche 64, die Teil der Außenfläche bildet;
• – Außenwand 66 der vorderen Deckelwand 21;
• – Innenwand 67 der vorderen Deckelwand 21;
• – Innenfläche 69 der Deckelplatte 19;
• – Innenfläche 71 der hinteren Deckelwand 27;
• – die Abschnitte 52, 53, 54 und 44 der hinteren Bodenseitenwand 17 entsprechend den anderen Bodenseitenwänden 13, 15, 11.

Opposite the front wall 11 closes on the ground 9 the outer surface 63 the back wall 27 followed by the sections of the lid body 5 , In a straight line these are:

• - upper lid surface 64 which forms part of the outer surface;
• - outside wall 66 the front lid wall 21 ;
• - inner wall 67 the front lid wall 21 ;
• - Inner surface 69 the cover plate 19 ;
• - Inner surface 71 the rear lid wall 27 ;
• - the sections 52 . 53 . 54 and 44 the rear floor side wall 17 according to the other bottom side walls 13 . 15 . 11 ,

Laterally on the upper lid surface 64 are the outer walls 73 and interior walls 74 the lid side walls 23 educated. In the prefabricated state is the inner wall 74 around the line of weakness 75 around on the outside wall 73 put on and glued to this.

To form the box become the glued side walls 23 . 25 . 13 . 15 of the lid body 5 and the soil body 3 established. The part starting with section 67 gets around the line 77 folded over, leaving the inner lid surface 69 on the upper lid surface 74 to come to rest. The gussets 79 between front outer wall 66 and the side walls 23 . 25 come in between the outer wall 66 and the inner wall 67 the front lid wall 21 lie, resulting in a stable, upright configuration of the lid walls 21 . 23 and 25 results.

section 71 lies as an inner wall on the outer surface 63 the rear lid wall 27 on. When erecting the side walls 13 . 15 became the stabilizing tabs 81 to the section 63 bent down so that the rounded protrusion 83 across the cavity walls 13 . 15 stands. Between the apex of the rounded protrusion 83 and the respective outer wall 52 become the slip-in tabs 85 laterally on the outer wall 52 the back wall 17 inserted. The slip-in tabs 85 are rounded at the top to facilitate this insertion movement caused by kinking along the line 87 he follows. It also horns 88 on the top surface of the rear bottom side wall 17 in the side walls 13 . 15 inserted. To facilitate this process are rounded areas 90 . 91 at the back ends of the deck surfaces 53 and interior walls 54 , The rounded areas 90 . 91 make a cut at the edge between the two sections 53 . 54 through which the horn 88 can slide.

The side flaps 89 laterally on the inner surface 54 the bottom back wall 17 are folded backwards so that they are in the bottom back wall 17 in point. They thus stabilize the interior of the rear wall 17 and thus the pressure of the foot strap 44 This sidewall, attached to the glued-down foot straps 40 lying on the ground 9 is up.

A movement of the back wall 17 of the soil body 3 This prevents the outside section 63 the lid rear wall on the transverse stabilizing tabs 81 and the rounded protrusions 83 is applied.

Assuming that the fold is around the inner lid section 69 on the outer lid section 64 to lay, the viewer is done, lie the visible surface of the lid inner surface 69 as well as the visible surfaces of top lid surface, bottom 9 and the side walls of the lid and bottom on the side facing away from the viewer of the blank. All of these surfaces can thus be printed and designed by means of a low-cost, single-sided printing or other surface design methods.

From the foregoing description of a preferred embodiment modifications and developments are the skilled person accessible, without departing from the scope of the invention, which is given by the claims.
