Description

Description: The present invention relates to a box, in particular a box for letter envelopes.

For packaging and transport of various goods boxes are used. The boxes serve to protect the contents. With a box, a number of small parts can be combined to form a larger, easy-to-handle packaging unit. Also known is the use of cartons for storing and dispensing items.

The object of the present invention is to provide an improved box. In particular, the object is to provide an improved box for shipping, storage and convenient removal of letter envelopes.

This object is achieved by a box with the features of claim 1.

The box according to the invention is a box with a bottom part with a bottom and associated side walls which surround a bottom opening of the bottom part and of which at least one part is connected in pairs, and with a side flap as or in one of the side walls , Thus, one or more sidewalls can be opened as a whole or as part of it. In addition, a lid is provided with a lid part which covers the opening of the bottom part. The lid has at least two lid side panels connected to the lid member defining a box corner. Consequently, the mentioned lid side walls collide at one edge. A part of the lid part forms with a part of the lid side walls a hinged unit. In a closed state, the hinged unit overhangs the side flap at least in an area on the box exterior.

Filling and removal of content happens, with the lid open, through the first opening of the bottom part of the box therethrough. This opening, which is opposite to the ground, is covered by the cover part. The box also has an alternative access to the removal of objects, namely through the lateral opening which is covered by the side flap. Part of the lid can be opened without having to lift the rest of the lid. This part includes a part of the cover part and the at least two lid side walls. If this hinged unit is opened, the side flap is released and can be folded outwards. Through the resulting side opening of the box items can be removed without the whole lid must be opened. This is particularly advantageous when the carton is in a rack or cabinet and the available space above the carton does not allow the carton lid to be opened without first removing the carton from the rack or cabinet. By folding the side flap and lowering the hinged unit, the side opening is closed again and secured against accidental falling out of objects. The fact that the side flap, in an area on the box exterior, is overhanged by the hinged unit, is prevented in the lowered state that the side flap works outwards. The side flap is secured with it. In the hinged unit meet three flat elements in a corner and thus form a dimensionally stable unit, in particular, the angle between the first lid side wall and the part of the top surface, which belongs to the hinged lid part, kept stable. For example, a fold line in the lid divides the lid surface into a part associated with the hinged unit and into a remainder of the lid surface. Thus, the hinged lid part can be opened and closed independently of the rest of the lid.

Another advantage of the inventive box is that the height of the lid side walls can be made large compared to the height of the box, without thereby handling when removing content is cumbersome. A large height of the lid side walls leads to high stability of the box. The box is less easily deformed and thus better protects the contents.

Further embodiments of the invention will become apparent from the claims 2 to 13.

In one embodiment, which, unless contradictory, is combinable with all of the aforementioned and yet to be mentioned embodiments, the side flap is formed as part of a side wall.

Characterized in that the side flap is formed only by a part of a side wall, the lateral falling out of content from the box with open side flap is prevented in a simple manner.

In one embodiment, which, unless contradictory, can be combined with all of the aforementioned and yet to be mentioned embodiments, the side flap is foldable around a, preferably continuous, straight fold line.

In one embodiment, which, unless contradictory, can be combined with all of the aforementioned and yet to be mentioned embodiments, the fold line is parallel to the ground.

In one embodiment, which, unless contradictory, can be combined with all of the aforementioned and yet to be mentioned embodiments, the fold line divides the side wall into two parts.

In one embodiment, which, unless contradictory, is combinable with all of the aforementioned and yet to be mentioned embodiments, the side flap is fastened along at least one perforation line on a side wall.

As long as the perforation line (s) in the side walls is not torn, the box according to the invention can be used just like a previously known box for packing and shipping goods. It has a higher stability in this state than with open side flap. In a few steps, the inventive box can be changed so that an alternative access for removal of items from the box is created. The side flap can easily be folded outwards by tearing or cutting in the perforation line (s) which initially hold the side flap.

In one embodiment, which, unless contradictory, can be combined with all the above-mentioned and yet to be mentioned embodiments, the hinged unit is hinged to a straight in the cover part, preferably continuous, fold line.

In one embodiment, which, unless contradictory, is combinable with all of the aforementioned and yet to be mentioned embodiments, the hinged unit along at least one perforation line is attached to a lid side wall.

As long as the perforation line (s) is not torn in the lid / are, the inventive box can be used just like a previously known box for packing and shipping of goods. By tearing or cutting the perforation line (s), the hinged unit of the lid is free to move. This part of the lid can then be opened without having to open the rest of the lid. The perforation lines in the lid are laid so that the hinged unit, as mentioned, at least part of a first and a part of a second lid side wall, and a part of the lid part belong.

In one embodiment, which, unless contradictory, is combinable with all of the aforementioned and yet to be mentioned embodiments, a recess is formed as a handle or handle for a single finger in a cover egg sidewall and / or in the side flap.

Such handles or handles for individual fingers facilitate handling and make the user intuitively use the box according to the invention intuitively.

In one embodiment, which, unless contradictory, is combinable with all the above-mentioned and yet to be mentioned embodiments, the lid along a hinge edge with a side wall of the bottom part is hingedly connected.

In this embodiment, the lid is designed as a hinged lid. The box is one piece. This can be punched out of a single piece of flat material a blank for the box.

Quite conceivable, it is also, as further mentioned below, to perform the box in two parts.

In one embodiment, which, unless contradictory, is combinable with all the above-mentioned and yet to be mentioned embodiments, a slot or perforation line is provided beginning at an end point of the joint edge, in the cover part.

In one embodiment of the embodiment just mentioned, the slot or the perforation line ends at a fold line which extends straight in the cover part and which preferably runs parallel to a lid side wall defining the corner.

In this way, for example, a perpendicular to the hinge edge of the lid extending fold line in the top surface is possible.

In one embodiment, which, unless contradictory, is combinable with all the above-mentioned and yet to be mentioned embodiments, the box is formed of separate bottom part and lid and the lid part closes on all sides a lid side wall.

In this embodiment, the lid is designed as a slip lid. Hoods can be made very tight and dimensionally stable.

The shape of the inventive box is, for example, cuboid. The inventive idea can also be transferred to other forms of boxes. As a material for the box, for example, cardboard, single-layer or double-layer corrugated cardboard, plastic or a composite material can be used. The box is made, for example, by punching a mold of flat stock material and then folding it into the desired three-dimensional shape.

The connection between two side walls with each other or two lid side walls with each other, for example, by means of hinged on one of the sidewalls involved tabs which overlap with the other side wall and which are attached by gluing, stitching or positive interlocking hook on the overlapping side wall. This type of connection creates areas of sidewalls with twice the material thickness. Perforation lines preferably run at locations where only one layer of material is present.

Where a fold line occurs in the top surface or in the first side wall, it may be pre-scored, pre-scored or merely marked. If the box is made of corrugated cardboard, a fold line in the top surface or a fold line in a side wall may be parallel to the direction of the corrugated corrugations of the corrugated board. In this case, it is possible to dispense with pre-grooving or scoring. The ribs in this case ensure a neat folding along the fold line.

The dimensions of the box can be adapted to the intended content in a relatively wide range. For example, the height and width of the first side wall may be slightly larger than the size of envelopes to be packaged.
