Description

The invention relates to a one-piece blank, in particular of cardboard, cardboard or plastic, for forming a cuboid container having two longitudinal and transverse walls, with a rear wall and a front wall, wherein the front wall has at least one surrounded by a peripheral perforation first region, the is detachable from the separation perforation from the front wall. Furthermore, the invention relates to a container produced from such a one-piece blank. Due to the required folding of the one-piece blank for producing the container, such a container is also referred to as a folding box.

In a known blank of the type mentioned above, it is necessary for a customer to detach the area surrounded by the separating perforation at the perforation in order to be able to use the container as intended. Such separable areas are used in particular for packaging of substances that are to be continuously released over a longer period of time to the ambient air, as is desired, for example, insect repellents or insect repellents and room deodorants. In this case, the region delimited by the peripheral region of the separating perforation should remain in the front wall of the container as long as a material outlet from the container is not yet desired. In this case, the substance to be dispensed can additionally be arranged in an airtight packaging in the interior of the container, which is only opened when the agent is to be dispensed over the area separated out of the front wall.

The separation perforation in such known containers must be designed so that it is not accidentally cut out on the one hand during transport and storage of the container and on the other hand by a person without much effort and without damaging the rest of the container is detachable from the front wall when the container is used as intended.

The invention has the object of providing a blank of the type mentioned in such a way that at least the separation of at least one of a separating perforation surrounded area of the front wall of the container is simplified.

To achieve the object, it is proposed according to the invention that the blank described at the beginning has a first section forming the container and at least one second section which is arranged at least in front of at least a partial area of the front wall and which is connected to the area surrounded by the separating perforation. Thereby, when lifting the second portion of the front wall, in particular when leaving the second portion of the container, the area surrounded by the separation perforation area detached from the front wall, so that alone by the lifting of the second portion of the front wall, each surrounded by a separation perforation and with the second area associated areas can be separated out of the front wall. The second section preferably covers the first area over a large area so that the detachable from the separation perforation area in the front wall during the transport and storage of the container is safe from accidental separation prior to putting the container into use. Preferably, the second section contacts the front wall in a partial area of> = 50%, preferably> = 80%, of the area of the front wall.

Further, it is advantageous if the front wall has a plurality of areas surrounded by a circumferential separation perforation, preferably four, five, six, seven eight and nine such areas, which are respectively detachable from the respective peripheral peripheral separating perforation from the front wall and if the second section the blank arranged at least in front of these detachable areas and connected to these areas each. Thereby, when lifting the second portion of the front wall all surrounded by the Tren n-perforation and connected to the second portion areas can be separated in one operation from the front wall. Preferably, the first region and the possible further regions surrounded by a separating perforation are glued to the second region. As a result, a secure connection between the detachable areas and the second section is possible.

By a suitable connection between the separable regions and the second portion, a connection force is generated which is greater than the force necessary to separate the separation perforation. Furthermore, the front wall and / or the rear wall may have at least one support element region surrounded by a peripheral perforation, wherein the perforation on one side of the support element region as a buckling perforation formed along a line is formed, and wherein the remaining part of the peripheral perforation delimiting the support element region is formed as a separating perforation. As an alternative to kink perforation, a kink can be provided on one side of the support element region, which has been produced in particular by grooves. In this case, the support element area is then not limited by a circumferential perforation but by a Knickkannte and the support member region otherwise limiting Trennperforation. As a result, the support element region can be easily detached from the front wall of the container, but remains connected via the kink perforation or the Knickkannte with the front wall. It is advantageous that the separate from the separation perforation and kinked at the buckling perforation or Knickkannte in the direction of the opposite wall contacted the opposite wall, wherein at a trained in the front wall support element area, the opposite wall is the rear wall and wherein at a in the Rear wall trained support element area the opposite wall is the front wall. By means of a support element region, the distance between the front wall and the rear wall can be maintained at a desired distance at least in the region of a support element formed by the support element region. In particular, the front and rear walls can be compressed by the support force generated by the support member only with a relatively high compressive force in the space defined by the support member distance between the front and rear walls.

It is advantageous if the support element has a contact area when contacting the opposite wall. Through the contact area, the position of the opposite wall facing the end of a support portion of the support member can be easily kept in a desired position. Preferably, the support element region of the support element is bent at 90 ° in the direction of the opposite wall at the kink perforation, wherein the contact region is bent relative to the support region of the support element at another kink edge, so that at least a portion of the contact region contacts the opposite wall surface.

It is advantageous if the contact region is connected to the rest of the support element region via a kink perforation or via a grooved connection region. It is also advantageous if at least four support element regions are formed in the front wall.

It is advantageous if the force required to separate the buckling perforation is greater than the force required to separate the separating perforation, in particular at least twice as large, preferably at least 10 times as great. In this case, the separating perforations and / or buckling perforations and alternatively or additionally Knickkannten between front wall, rear wall, longitudinal and transverse walls may be formed by punching.

Furthermore, it is advantageous to design at least one of the transverse walls as a resealable closure flap. As a result, then a simple access to the interior of the container is possible. Preferably, in Inside the container an insect-killing, insect-repelling, butterfly-destroying and / or moth dispersing means provided. Alternatively or additionally, an agent serving as a room deodorant may be accommodated in the interior of the container. This agent can then pass over the cut-out area or over the separated areas of the container to the ambient air. Another aspect of the invention relates to a container consisting of a blank according to the invention.

An integral blank is in particular made from a single sheet. The sheet may consist of cardboard, paperboard, in particular corrugated cardboard or hardboard, or of plastic or of a laminate made of these materials.

Further features and advantages of the invention will become apparent from the following description, which illustrates the invention with reference to embodiments in conjunction with the illustrated figures.

The blank 10 has a first portion 12 that includes a front wall 14, a first longitudinal wall 16, a rear wall 18, a second longitudinal wall 20, a lower transverse wall 22, and an upper transverse wall 24. The lower transverse wall 22 is connected via a Knickkannte 25 with a lower locking tab 26 and the upper transverse wall 24 is connected via a Knickkannte 29 with an upper locking tab 28.

The first longitudinal wall 16 is connected via a first Knickkannte 15 with the front wall and a second Knickkannte 17 with the rear wall 18. The second longitudinal wall 20 is connected via a first Knickkannte 19 with the rear wall 18 and connected via a second Knickkannte 21 with a second portion 30 of the blank 10. The lower transverse wall 22 is connected via a Knickkannte 23 with the rear wall 18 and the upper transverse wall 24 is connected via a Knickkannte 25 with the rear wall 18. From the rear wall 18, a tab 34 can be released via a separating perforation 32, which tab is connected to the upper transverse wall 24 after being released via the knickknack 25. From the tab 34, a region 36 which is surrounded by a peripheral separating perforation 38, herauslösbar, so that after the detachment of the container via the tab 34 on a passed through the cut-out portion 36 holding means, such as a hook, can be maintained.

In the first longitudinal wall 16 there are three openings 40 to 44 and in the second longitudinal wall 20 there are three openings 46 to 50 through which air can enter the container 200 and exit from it. Further, the first longitudinal wall 16 is connected via a Knickkannte 52 with a locking tab 54 and a Knickkannte 58 with a locking tab 60. The second longitudinal wall 20 is connected via a Knickkannte 62 with a locking tab 64 and a Knickkannte 66 with a locking tab 68.

The front wall 14 has a total of nine limited by circumferential perforations areas 70 to 86, which are detachable by separating the limited perforations from the front wall 14. The separation perforations are in the figures as dashed lines and Kickperforationen, Kickkannte and Körperkannten are shown as solid lines. Furthermore, there are areas 88 to 94 in the front wall 14 which are over in each case a kink perforation 96 to 102 as well as in each case a Tren n-perforation 104 to 110 circumscribed limited.

In FIG. 2 is the blank 10 after FIG. 1 illustrated with adhesive wetted areas 112 to 128 are shown as hatched areas. As in FIG. 2 As shown, the regions 70 to 86 are each wetted with adhesive in an inner portion 112 to 128. The adhesive regions 112 to 128 have a circumferential distance to the separating perforation line surrounding the respective detachable region 70 to 86 in the range between 0.5 mm and 3 mm, so that it is ensured even with conventional production tolerances that no adhesive is applied to regions of the front wall 14 outside of The detachable regions 70 to 86, which are surrounded by the separating perforations, strike. Further, another adhesive colored area 130 is provided near the left outer edge 132 of the blank 10. Depending on the embodiment, this region 130 has a constant width in the range between 3 mm and 10 mm and a distance from the outer edge 132 in the range between 0.5 mm and 5 mm.

In the in the FIGS. 4 and 5 2, the second portion 30 is disposed in front of the front wall 14 such that the area between the creases 21 and the perforation 31 is located above the adhesive-wetted area 130, so that this area between the creases 21 and 31 is above that with glue wetted area 30 is bonded to the front wall 14. Furthermore, the peripherally circumscribed areas 70 to 86 from the separating perforations are over the adhesive wetted areas 112 to 128 with the second portion 30 connected so that after the production of the adhesive bond in a subsequent lifting of the second portion 30 of the front wall 14, the areas surrounded by the perforations 70 to 86 are separated from the front wall 14 and remain on the second section.

The second section 30 can then be separated at the perforation line 31 from the container 200, as shown in the Figures 3 and 5 is shown. Furthermore, the tab 34 has been removed from the rear wall 18 at the separating perforation 32 and swiveled by 180 ° at the bend edge 25. Furthermore, the region 36 has been removed from the tab 34 at the separation perforation 38, so that the tab 34 now has an opening 36 through which a holding means for holding the container 200 can be inserted.

In FIG. 4 FIG. 3 is a perspective view of a container 200 taken from the blank 10 according to FIG FIGS. 1 to 3 has been produced. In this case, the second portion 30 has been folded away in the direction of arrow P1 from the front wall 14 of the container 200 on the perforation line 31. In this case, the detachable regions 70 to 86 connected to the second section 30 via the areas wetted with adhesive 112 to 128 have been separated out of the front wall 14 and stick as in FIG FIG. 4 shown at the second portion 30, so that in the front wall 14 by the unfolding of the second portion 30 in the direction of the arrow P1 a total of nine openings in the front wall 14 have been generated. The second section 30 can now be separated at the separation perforation 31 from the container 200, as shown in FIG figure 5 represented by the arrow P2. The identities generated by the separation perforation separation are in FIG. 5 designated by the reference numeral 31.

Further, the support member portions 88 to 94 are separated at the separation perforations 104 to 110 from the front wall 14 and pressed down, wherein the support member portions 88 to 94 are pivoted about the pivot axis respectively generated by the respective buckling perforations 96 to 102. As a result, a contact region 134 to 140 of each support element region 88 to 94 makes contact with the inside of the opposite rear wall 18. It is advantageous if the contact regions 134 to 140 rest flat on the rear wall 18 at least in a partial area and with a contact area of the contact area remaining support portion 142 to 148 caused force against the rear wall 18 are pressed so that the support portions 142 to 148 are substantially parallel to the longitudinal walls 16, 20. The closure elements formed by the transverse walls 22, 24 and the closure tabs 26, 28 connected thereto are in the FIGS. 4 and 5 shown in the open state in which the container 200 can be filled or emptied.
