Containers for elongated objects

The invention relates to a method for producing a container for elongated objects and a container for elongated objects manufactured according to this method. It is a container with a recessed area for the aligned side-by-side arrangement of the objects, preferably made of transparent plastic, with a fastening edge running outside the recessed area, which is connected to a bottom part that holds the objects placed in the recessed area in place is.

In known containers of this type, the inclusion of elongated objects in the form of tools, in particular drills, or writing utensils, such as. B. colored pencils or fiber pens are usually formed in the form of blister packs. The molded parts having the recessed area for receiving the objects are usually connected to a fastening part running outside the recess with a film part formed by a printed cardboard strip, usually by gluing or welding or simply by means of staples. In this state, they form practical, inexpensive sales units in self-service shops. When opening such containers, however, the molded parts containing the inserted objects have to be more or less forcibly separated from the film part forming the container closure, the latter being destroyed, so that the molded parts - if at all - can only be used as bowl-shaped containers. However, there is often a need for reclosable containers which are used for the orderly storage of the elongated objects.

At this point it should be mentioned that containers in the form of transparent cases are already known in the market, which in their front area comprise a flipped-over soft, deformable flap, for the securing of which an additional welded-on transverse clip is provided. Such case-like containers can only manually fill and seal. As a guarantee closure, a self-adhesive label is usually stuck overlapping the flap and the top of the case. On the one hand, this method of production requires at least two materials to be brought together. In addition, the time required for container manufacture and filling is relatively large.

In order to be able to offer such well-known cases on the market in self-service shops, it is known to insert them with the required information into a transparent deep-drawn part after attaching a self-adhesive label and to blister on a cardboard base or to skinn using a film (without deep-drawn part) . In a subsequent step, a small tab must be punched out of the back of the pack in order to use it for hanging on a self-service stand.

The invention has for its object to provide a manufacturing method for a container with which the container can be easily and efficiently manufactured as a case. Furthermore, the invention has for its object to design a simple and rationally manufactured container so that it is designed as a case and can be opened easily and can be reclosed after removal or return of an object.

Claim 1 relates to an inventive method for producing a container of the type mentioned. It is characterized essentially by the fact that to form a receptacle, the deep-drawn front part of a strip of plastic material is glued or welded to the bottom part while maintaining the fastening edge and the case -External contour in the area of the fastening seam running along the fastening edge is fixed by punching out and, in this or in a separate working step, the deep-drawn front part by placing a punch cut line in an upper part, which comprises a handle tab serving for the container closure, and a lower part forming the actual receptacle towards the bottom part ensuring the connection of the two parts, while leaving a punched cut line section that may only be torn open at the time the case is used. The container according to the invention as claimed in claim 2, in which this object is achieved, is essentially characterized in that, in order to form a receptacle in the form of a case, the front part, which is deep-drawn from a strip of plastic material, is glued or welded to the base part while maintaining the fastening edge, and the outer case contour in the area of the fastening seam running along the fastening edge is determined by punching out and, in this or in a separate working step, the deep-drawn front part by placing a punch cut line in an upper part, which comprises a handle tab serving for the container closure, and a lower part forming the actual receptacle towards the bottom part which ensures the connection of the two parts, while at least largely leaving a punched cut line section which may only be torn open at the time of use of the case.

Such a container can be designed in this simple manner as a flip case, from which the elongated objects can be conveniently removed after opening and pivoting the grip tab and can also be easily returned to the latter after use. The fact that the punching over large areas of the front part of the container only weakens the plastic material and only really cuts through the material in the area of the grip tab in the middle of the case, ensures that the customer opens the finished, filled case for the first time. By coordinating the material - front part hard, bottom part softer, a case is created, the grip tab of which can be easily reset after opening.

The container according to the invention advantageously offers the possibility of simply filling from a deep-drawn part made of a uniform material through the largest opening located thereon. If, for example, the elongated objects are writing implements, namely colored pencils or fiber-tip pens, these can be separated by machine and fed together to a recording unit. If a filling machine is used that does not run faster than the thermoforming machine used, then a particularly inexpensive assembly is possible in that the filling can be done mechanically. Advantageously, a loose label can be inserted beforehand, which provides information about the content and possibly takes into account the requirements of the legislator. After filling and welding the bottom part, as already mentioned, the outer contour of the case is punched out of the blank. After this stamping step, the upper part (tab) and lower part (receptacle) of the original deep-drawn front part are also separated from one another and are only connected via the welded-on base part.

It is also to be emphasized as advantageous that the container can be designed as a case, which simultaneously serves as a presentation unit and as a storage means for the end consumer. In this way, the container according to the invention saves packaging material on the one hand. On the other hand, the case according to the invention can be recycled if one makes use of the possibility now given to limit itself to only one type of material when producing the case.

It has proven to be particularly expedient if the stamped cut line in the upper quarter, which in some cases is only incompletely punched out, is used to separate the upper part and lower part of the front part of the case, forming the case closure grip tab, starting from the upper end of the deep-drawn region of the shaped part in an approximately circular arc is. This makes it possible to open the top of the elongated objects, e.g. B. the crayons or felt pens in a freely accessible position. After removal, the tab returns to its initial closed position, relieving the tension of the tab parts deformed during the opening process.

It has turned out to be very favorable with regard to a perfect alignment of the elongated objects within the recessed area of the container if protruding separating ribs are formed in the recessed area of the front part of the case with a mutual spacing that corresponds to the thickness or the diameter of the elongated Objects corresponds. For this purpose, series of rectilinear egg-shaped configurations aligned in a straight line to one another are conveniently provided for this purpose. In this way, recessed areas of the front part of the case are formed ensure that the elongated objects, for example the individual pens, cannot move diagonally in the case if part of the content has been removed.

Freer accessibility of the elongated objects after opening the case is achieved in a further embodiment of the container according to the invention in that when the die cutting line separating the upper part of the front part of the case from the lower part is drawn, that area of the upper part designed as a grip tab, which in the closed case state covers the upper ends of the elongated objects by cross lines to the punch cut line, approximately parallel to the fastening edge in the immediate vicinity of which is formed in the form of a pivotable cover flap of the case-grip tab.

Further details, advantages and features of the invention will become apparent from the following description with reference to the accompanying drawing, in which:

1 is a perspective view of a case according to the invention for accommodating elongated objects,

2 is a plan view of the case illustrated in FIG. 1,

Fig. 3 is a schematic side view of the case shown in Fig. 2 and

FIG. 4 shows a schematic sectional view corresponding to the side view of FIG. 3 with the grip tab transferred in the open state.

As can be seen from the drawing, the illustrated container for elongated objects is made of a front part 1 made of preferably transparent plastic and a bottom part 2, preferably also made of plastic, by welding the edge region of the front part 1 to the bottom part 2. For accommodating elongated objects Objects, e.g. B. colored pencils or fiber pens or also of tools, namely drills, the front part 1 is formed to form a deep area 3 deep-drawn from a strip of plastic material. During deep drawing, the recessed area of the case front part 1 is simultaneously provided with separating ribs, in the illustrated example in the form of series of elliptical shapes 4 aligned in a straight line to one another. The separating ribs formed by these features are pronounced in the recessed area 3 with a mutual spacing, the thickness or corresponds to the diameter of the elongated objects to be accommodated in the container. In the illustrated example, the elongated objects are writing implements 5, namely colored pencils, fiber-tip pens or the like.

As shown in Fig. 4, the case designed in the form of a case is provided with a grip tab 6, which is formed by the upper part 1a of the case front part 1 and with the lower part 1b, which forms the actual receptacle, via which the pivotable hinge-like connection bottom part 2 securing both parts connected at 7. For this purpose, the front part 1 is welded to the base part 2, which preferably consists of a soft plastic film. The outer contour 8 which can be seen in the drawing is determined in the region of the fastening seam running along the fastening edge by punching out. Simultaneously with this punching process or in a separate work step, the deep-drawn front part 1 is separated by placing a punch cut line 9 in the upper part 1a, which includes the handle tab 6 serving to close the container, and the lower part 1b forming the actual receptacle. In this punching process there may be a slight connection between the two parts via the tearable punch cut line 9 created by material weakening during punching, which in this way forms a guarantee closure. If the weakening of the material is dispensed with, ie the punch cut line is punched through, the use of an adhesive label or the like is required to seal the case. 1 and 2 show that the separation of the upper part 1a and lower part 1b of the case front part 1 to form the case closure handle tab 6 serving z. T. only incompletely punched-out cutting line 9 in the upper quarter, starting from the upper end of the deep-drawn region 3 of the molded part, is approximately circular. When the punched cutting line 9 separating the upper part 1a of the front part 1 of the case from the lower part 1b, that region of the upper part which covers the upper ends of the elongated objects 5 in the closed state of the case is made by laying transverse to the punched cutting line 9, and that approximately parallel to the fastening edge or the outer contour 8 in its immediate vicinity dividing lines 10 in the form of a pivotable cover plate 11, cf. Fig. 4, the case grip tab 6 is formed. If the case front part 1, which is subjected to a deep-drawing process, and thus also the grip tab 6 with the cover tab 11 are formed from hard plastic, preferably from hard PVC, this not only results in greater rigidity and strength; rather, relatively high restoring forces are also advantageously achieved. When pivoting the grip tab 6 from the position shown in FIG. 4 into a position in which it projects approximately transversely to the rear, it can be used as a support, ie as a stand, and the contents of the container are conveniently presented to the user for removal.

In the front part 1 of the case, when the recessed area 3 is deep-drawn, in addition to the inwardly projecting separating ribs in the form of the embossments 4, a raised field area 12 is used to accommodate a labeling strip which characterizes the content.

1 and 2 show that in the upper case edge area a perforation 12 is made possible to enable the case to be arranged on a sales aid.

In the above example it is provided that a relatively soft plastic film is used as the base part 2, which enables the front part 1 to be welded to the base part 2. Instead, the two parts could also be connected to one another using the hotmelt process. Instead of the soft plastic film, a plastic-coated cardboard could also be used to form the base part 2, in particular if it permits welding, but is also accessible by a hot-melt process. It is only important that this plastic-coated cardboard ensures the pivotable connection of the handle tab 6 indicated at 7 according to FIG. 4 with the actual receptacle of the case.
