Definitions

• the present invention relates to a device for distri- t - buting packaging material.
• the packaging material prefer ⁇ ably is in the form of bags, e.g. of plastic, for packag ⁇ ing different types of products, such as food, e.g. loaves of bread, but also other products, such as serviettes or table-cloths.
• 10 Automatic packaging in bags, also of such unrelated product groups as those mentioned above, is carried out more or less in the same manner.
• Preprinted bags, prefer ⁇ ably made of plastic are placed in a packaging machine where one bag at a time is inflated to render accessible lt - the bag opening so that the product may be introduced into the bag. Then, the bag now containing the product is sealed and taken away.
• FR-A-2,385, 589 discloses another type of retainer hoop. In this case, however, the purpose of the bags and the hoop is completely different from that of the device according to the present invention.
• a locking means e.g. in the form of an apertured rubber plate, is provided at each free end of the hoop on the rear side of the backing.
• a band encloses the bags and the backing to prevent the bags from sliding on one another and becoming deformed during transport.
• the stack of bags is also placed in a box for distribution to the user, e.g. a bakery.
• FR-A-2,009,290 discloses a box blank which is mainly made up of a bottom, side panels, and top panels covering the short sides.
• the user opens the box and the retainer hoop is fastened in the packaging machine, whereupon the band, if any, is removed and the packaging of the products begins.
• the stack of bags is extremely difficult to handle even if a very rigid backing is used.
• the slippery bags slide against one another, and the risk that the bags are creased or folded is considerable, especially when the stack is placed in the box.
• the same inconvenience faces the user who may have to scrap a number of bags and, in some cases, also the product itself, e.g. a loaf of bread which is not caught in the bag but lands on the floor.
• Another well-known inconvenience is the so-called "block- ing" which occurs when a stack of plastic bags is pressed together.
• One object of the present invention is, therefore, to provide a device for distribution of packaging material which has fewer component parts and thus greatly facili ⁇ tates the handling both by the manufacturer and by the user, and ensures a high product quality throughout.
• a device for distributing packaging material comprising a plurality of bags for packaging different types of pro ⁇ ducts, and a U-shaped bag retainer hoop adapted to be fastened in a packaging machine, characterised by a box blank which, in transport position, forms a rigid trans ⁇ port container at least partly enclosing the bag retainer hoop and the bags and having a bottom which supports the bags and the hoop, side panels which laterally surround the bags and the hoop, and interconnected top panels which at least partly cover the bags and the hoop.
• Fig. 1 is a perspective view of a known stack of bags
• Fig. 2 is a top plan view of a first embodiment of a" blank adapted to f-orm a transport container for bags
• Fig. 3 is a perspective view of the transport con ⁇ tainer formed from the blank in Fig. 2,
• Fig. 4 is a top plan view of a second embodiment of the blank adapted to form a transport container for bags, and
• Fig. 5 is a perspective view of the transport con ⁇ tainer formed from the blank in Fig. 4.
• Fig. 1 illustrates the known technique of packaging and distributing bags for different types of products.
• bags 2 are fixed to a backing 6, preferably made of cardboard.
• Each leg 8, 10 of the retainer hoop 4 is securely held in position by locking means 12 and 14, respectively, in the form of circular rubber plates formed with a central hole.
• locking means 12 and 14 respectively, in the form of circular rubber plates formed with a central hole.
• a band 16 is tied around the bags and the backing.
• corner areas 18a, 18b, 18c and 18d of the bags are liable to external damage, such as creasing, and that the entire stack is subjected to the risk of blocking, which may force the user to scrap the bag/bags and, in some cases, also the product, either because the bag cannot be opened to receive the product which then lands on the floor beside the packaging machine, or for aesthetical reasons.
• Figs. 2 and 3 illustrate a first embodiment of the device according to the invention.
• Fig. 2 is top plan view of a box blank 20 adapted to form a transport container 22 which is shown in perspective in Fig. 3.
• the box blank has a substantially rectangular surface 24 which is to form the bottom of the transport container 22.
• Side panels 26, 28, 30 and 32 are to form the side walls of the container, and top panels 34, 36, 38 and 40 are to form the upper side or top thereof.
• the top panels 36 and 40 have adhesive areas 36a, 36b and 40a, 40b, respectively, (see Fig. 2) so that the top panels 36 and 40 can be attached to the panels 34 and 38, respec ⁇ tively, to form a substantially parallelepipedal body.
• Each bag has two holes, and the distance between these holes corresponds to the distance between the legs of the retainer hoop.
• the legs 8, 10 of the retainer hoop are passed through the holes of the bags, whereupon the hoop with the bags, which for the sake of clarity are not shown in the drawing, is placed in a predetermined posi ⁇ tion of rest on the bottom 24 of the blank 20 near the side panel 28.
• the panels 26, 34 and 30, 38 are folded upwards, and the panels 28, 36 and 32, 40 are folded inwards at right angles to the panels 26, 34 and 30, 38, respectively, so that the adhesive areas 36a and 36b of the panel 36, and 40a and 40b of the panel 40 will adhere to the panels 34 and 38, respectively.
• the top panel 36 bends the hoop 4 down against the bags, such that the hoop 4 is maintained in place and its pointed ends are covered and that, furthermore, the area around the holes of each plastic bag is protected.
• the side walls and the upper side of a substantially parallelepipedal body 22 are formed, which at least partly encloses the bags supported on the bottom 24.
• FIGs. 4 and 5 illustrate a second embodiment of the device according to the invention. This second embodiment is similar to the first embodiment shown in Figs. 2 and 3, for which reason like reference numerals apply to like parts.
• Fig. 4 is a top plan view of a box blank 42 adapted to form a transport container 44 which is shown in per ⁇ spective in Fig. 5 and which highly resembles the con ⁇ tainer 22 shown in Fig. 3.
• the difference between the box blank 42 in Fig. 4 and the box blank 20 in Fig. 2 is that the blank 42 has flaps 46, 48, 50 and 52 at the short sides of the top panels 36 and 40. As stated below, these flaps are to be inserted into slits 52, 54, 56 and 58.
• the retainer hoop 4 with the bags which for the sake of clarity are not shown in the drawing, is placed in a predetermined position on the bot ⁇ tom 24 near the side panel 28, after a predetermined num ⁇ ber of bags have been fixed to the retainer hoop 4.
• the bags are supported on the bottom 24.
• the panels 26, 34 and 30, 38 are folded upwards.
• the slits 52 and 56 are formed on the folding line between the panel 26 and the panel 34, while the slits 54 and 58 are formed on the folding line between the panel 30 and the panel 38.
• Each of the slits 52, 54, 56 and 58 has a length corresponding to the extension of the respective flap in the longitudi ⁇ nal direction of the blank, i.e. they are slightly shorter than the short sides of the top panel 36, 40 at issue.
• the flaps 46, 48, 50 and 52 can thus be inserted in the corresponding slits 52, 54, 56 and 58, respectively, so as to form the substantially parallelepipedal body 44 shown in Fig. 5.
• the loose retainer hoop 4 is bent down against the bags when the top panel 36 is folded inwards to cover the hoop and protect the bags. It is preferred that the total area of the top panels 34, 36, 38 and 40 is smaller than the area of the bottom 24, so that an opening can be formed in the upper side of the erected transport container, thus allowing identifica ⁇ tion of the contents without opening the container.
• the corner areas of the bags are protected against mecha ⁇ nical damage, such as creasing and bending. Blocking of the stack of bags is prevented also when a plurality of transport containers are superimposed, as for example in a storage.
• the side panels 26, 28, 30 and 32 are folded upwards to form a box-shaped container completely open at the top, and the retainer hoop with the bags is thereafter placed on the bottom 24. Then, the top panels 34, 36, 38 and 40 are folded inwards to form the transport container.
• the transport container according to the invention is useful also to the user.
• the bags which are well pro ⁇ tected, retain their high quality almost regardless of how the transport container is handled.
• the rigid transport container makes it easy to store the bags, and the con ⁇ tents of the container are readily identified through the opening. Furthermore, the monotonous manual application of hoop locking means is avoided.
• the embodiments described above and shown in the drawings are only examples of the present invention.
• the design of the transport container depends on the shape of the bag to be filled and distributed.
• the materials for the bag and the container may be other than stated above.
• the adhesive areas may be located elsewhere, e.g. on the elongate top panels 34, 38.
• the appended claims embrace all such variants and modifications.
