"Behäl tnis such as sleeve, container or the like - for the reception of goods"

Γ ie I'rf indunr concerns the packing of goods and ir.sh'iHon-iere containers or envelopes C and "blanks f * '5r these" for the reception of goods, whereby such "7 eh old he or envelopes, in one of their Manufacturing states a container or envelope cutting phase au '.'■>: e Ipen, in such a way that the erection from the blank results in the container or the envelope.

The containers or envelopes according to the present invention '· Are for the inclusion of any one endless Determines the number of articles that represent goods of the type that are normally found on the counter Displayed and sold by department stores or shops. Such goods can, for example, be food, Clothes, candy, tobacco and smoking supplies, metal goods, cosmetics, stationery and office supplies like writing utensils and many other

109847/1340

be those articles which are not covered by this general classification.

The use of containers and envelopes which ^ snz are made of cardboard is known and used; however, as items are displayed on counters training have been proposed, through which the contents of a container or a shell can be issued without rla / i er removed from the container or envelope got to.

With one of these. Training is a. Two-sided container is provided, which has a GtMr.d body for receiving the packaged goods or the articles and a transparent lid. Plastic such as ⁷ I ₁ Y-vinyl chloride, cellulose acetate or "olystjrcl has, which can be arranged to complete the packaging on the base body for the maintenance of its contents, so as ^ the content by the? Aterial of the cover seen v / This embodiment is relatively expensive and, moreover, presents difficulties in manufacturing the package which make this embodiment essentially unsuitable for erecting and pulling by automatic machines.

In another embodiment, which was used in contrast to covers for containers, a card is

109847/1340

BATH ORIGINAL

strand clay blank made of cardboard with a window, that is provided in a field or extends over several fields of the blank that however, is within the edge of the cardboard blank; this window is flexible with a Sheet covered with transparent plastic material, which along its edge against the inner surface of the cardboard blank is glued. When these containers are erected and filled, are cfe mistakes, at least in part, by the Plastic sheet covering window opening visible. There are many different forms of such containers, however, all of which suffer from the disadvantage that they are quite expensive because of a window in the carton blank must be provided and because in addition a La: niniervorgang to attach the plastic sheet to the carton blank is required.

The invention is based on the object of a container or a casing for receiving goods in such a way that the goods in the container or envelope can be seen and which or At least in some embodiments, however, it is cheaper to manufacture than the described embodiments.

According to the invention, a cover or a container for receiving goods has a flat cardboard part and a transparent flat plastic

109847/1340

part on, which are connected to each other in a construction state so that they are a composite Form blank, the edge of which partly through the cardboard edge and partly through the edge of the plastic part is formed, the assembled blank folding lines so that the assembled blank is folded to form the envelope or container can be.

As a result, it is not necessary that the cardboard part has a window opening, since the plastic part, through which the goods in the case or the container can be seen, a part of the assembled blank and is folded accordingly.

If the composite blank is intended to form an envelope, the plastic part extends preferably over the entire length of the envelope, being attached to the cardboard part along two seams which extend the length of the shell. The sheath can have any suitable cross-section, for example rectangular, square, polygonal or triangular cross-section, wherein the cardboard part and the plastic part are folded accordingly. The sheath ends can be closed by locking members be closed from cardboard or plastic material, which with a friction fit can be arranged in the shell ends or which can even be secured in their position, so

109847/1340

that the cover must be torn open in order to get to the contents. The case can be used by itself the support of a shell can be formed, which receives the packaged goods.

If the assembled blank is intended for a container, the blank preferably has Fields on which the container walls and a container base, with or without a top wall, form. The top can be designed as a cover and by suitable folding of the plastic part be formed by this. If the container is designed as a flat elongated box, the End walls preferably formed by push-in flaps, which by folding lines in the plastic part or in the Cardboard part can be formed.

In a preferred embodiment, the cardboard part 'forms the bottom, the front and rear walls and male end walls of the container during the Plastic part forms the top of the container and on the upper edges of the front and rear walls of the container is attached so that goods are secured prior to sealing the container ends with the end walls can be introduced through the ends into the container. Tuck-in flaps or labels, which are attached to the end walls and lie under the plastic part when the container is erected, can be provided with suitable prints for decoration or advertising.

Automatic splitting and gluing machines can be used to split the assembled blank, the blank being handled during this operation as if it were completely formed by a cardboard blank. If the assembled blanks are folded by machine, it is useful if the plastic part has a stiffness comparable to that of the cardboard box. Since in practice all of the assembled blanks are folded and glued by machine, this requirement is met in almost all cases. It has been found that stiff, clear polyvinyl chloride film having a thickness in the range of 150 microns (kl) is suitable to meet this requirement. Folds in the polyvinyl chloride film can be formed by grooves with a depth of about 50%. However, other plastic films, for example made of polystyrene and cellulose acetate, can also be used and, in addition, the plastic films can be colored while maintaining the transparency in order to achieve special effects in relation to the product or the goods which are included in the Sheath or the container are arranged.

As a rule, the connections between the KaP clay part and the plastic part are made by adhesives such as Adhesive is formed although other means such as radio frequency welding, heat sealing or mechanical Connection by tabs and slots are possible.

109847 / 13A0

In the case of envelopes or containers according to the invention, the amount of plastic film can be kept to a minimum while a large transparent area is given since a substantial part of the subject invention can consist of cardboard, which costs considerably less than plastic film and which is printed with conventional printing machines can be.

The assembled blanks can be produced by bringing together a cardboard blank ( which forms the cardboard part and a plastic film blank (which forms the plastic part) and by gluing and pressing these two blanks together along an overlapping edge or along overlapping edges be handled as if they were complete cardboard blanks, which possibility high production numbers of envelopes or containers according to the invention are possible.

The fold lines in the assembled blank can be exclusively in the box or exclusively be provided in the plastic film or in the more common case in both.

According to the invention, a blank is also proposed which has a flat cardboard part and has a transparent flat plastic part,
