DE7440246U - Packaging for flat objects - Google Patents

Description

The innovation relates to packaging for essentially flat objects, such as books, brochures, machine parts, Control buttons o.a., consisting of one through at least a glued seam of a closed tube section made of solid cardboard, corrugated cardboard, plastic, etc., which is delivered flat.

In particular, book packaging has become known which made from a relatively complex cut will. The disadvantage of this packaging, however, is that there is either a special one for each book size A cut must be created or, if a packaging size is used, cushioning material must also be used for smaller books must be used to fix the smaller book in the large packaging so that it can be transported cannot be damaged. Such packaging has also been specially developed for books can be used in each individual case for the packaging of in relation to the book / ' flat brochures or machine parts or control button «^ ' ie ^^ VaoSyenden.

The present innovation is therefore based on the task

to create a simply structured package, which Universal for a larger one without additional effort Number of books of different sizes, etc., can be used.

The solution to the problem is that there is one lock each flap with an inwardly curved line of weakness ending at the end point of the side edges at each open Is hinged at the end of the top and bottom.

The main advantage of this packaging is that the packaging can be delivered flat, so it saves space, but is then ready to be filled. Included It is important that for a considerable number of different sizes of the parts to be packed one and the same addition ~ cut can be used, so that storage can be significantly saved. For example, in the the same packaging size, a thin brochure and also a book several centimeters thick can be packed, whereby Both parts are securely packed in the new packaging and will not be damaged during transport. The particular rough handling occurring during mail transport due to the throwing of the packaging during sorting * - " is absorbed by the packaging without further ado. The packaged goods are safely protected from damage. In addition, a relatively light material can be used to manufacture the packaging, so that this can be used as a single pack. It is not insignificant that paper or cardboard is included belongs to environmentally friendly materials.

The attached model embodies an exemplary embodiment of the innovation, a flat blank being formed by gluing it to the factory edge 11 to form a tube section with the side edges 12 and the upper side I3 and underside 1 if therebetween. At each open end of the top 13 and the bottom Ii ₁ . is a closure flap 15 and 16 over

Weakening lines 17 and ιό articulated. Any line of weakness 1? and 18 ends at end point 19 on both sides of the side edges 12 and has an inwardly, that is to say toward the inside of the top and bottom, curved shape. Most of time these lines 17 and 18 form parts of an arc. The size of the curvature is in relation to the width of the package Each locking tab 15 and 16 is set approximately lens-shaped, the boundary lines 17 »18 and the intersection lines 20, 21 in the end points 19 the side edges 12 end. The locking tabs 15 on the top 13 have a tuck-in flap in the middle which is provided with locking lugs 23. The locking tabs 16 on the underside Hf have an insertion slot 2 / + in the weakening line 18, which through additional short cuts for locking the lugs of the tuck-in flaps 22 is set up. In addition, im Area of the slot 2 ^ a handle opening 25 is provided, whereby the tuck-in flap can be pulled out of the slot more easily when the packaging is opened. On the outer edge A further grip opening 26 is arranged on the closure tabs 16. In the inner wall of the upper and lower side are parallel to the side edges 12 two lines of weakness 27 ending approximately at the level of the Eincecklaschen 22 appropriate.

Even if all sheet-like substrates can be used as material, it is nevertheless expedient to use corrugated cardboard to use, the shafts being arranged so that them in the lock load rows 15 and 16 perpendicular to the Top and bottom run.

To use the packaging, the tube section, which is delivered flat, is spread apart in the middle and the book to be packaged is pushed in, which is firmly clamped by the tension on the side edges 12. The closure flap 16 is then folded in around the weakening line 18. Then each closing flap 15 is also folded in and the push-in flap 22 is inserted into the slot 2l \

inserted until the locking lugs 23 snap into place are. The closure flaps 15 and 16 form curved side walls through which the packaging is braced. This tension creates the strength of the packaging, so that even a fall onto a corner from a great height will do Packaged goods safely protected from damage.

The side or closure flaps 15 and 16 can each can be kept wider or narrower as required. They can even be of other shapes. That's the way it is possible, by appropriate choice of the shape of the cut edges 2o and 21 to achieve that the top 13 after hammering the closing flaps are arched over the contents of the package, while the underside is relatively flat which makes it easier to stack packs that have already been filled. Usually the Crease 2? reaches that the intermediate surface the top and bottom lies flat, thereby creating a support surface for stacking filled packs.

The packaging is opened in the reverse order, with the handle openings 25 and 26 providing valuable help in folding the push-in flap 22 out of the slot Zk and the locking flaps 16 out of the locking part.
