Description

TECHNICAL AREA

The invention relates to a container for receiving a geometric triangle. With such containers, a triangle of geometry can be stored gently and safely. Such geometric triangles (also called drawing triangles) are mainly made of plastic material. With improper use of these geometry triangles very easily break off their corners, whereby their utility value is more or less completely lost.

STATE OF THE ART

From the EP 1 632 146 A1 is a trained in the manner of a bag such container known. The container has two plates covering the two bases of a geometric triangle. The two plates are arranged parallel to each other and their mutual distance is such that a geometric triangle can be pushed into the hollow space between the two plates. In order to prevent accidental slipping out of a pushed into the container into the geometric triangle, protruding from the plates into the interior protrusions may be present at which the geometric triangle frictionally applied sufficiently firmly in the inserted state.

From the DE 20 2006 012 638 U1 is also a trained in the manner of a bag such container known. The two covering the bases of a geometric triangle plates are not arranged parallel to each other due to different thickness spacers, so that the mutual distance of the two plates is different. Thus, the distance near one pocket edge is smaller than at the other edge of the pocket running at an angle thereto. In this way, a geometry triangle inserted between the plates can be frictionally held between the two plates adjacent to the one pocket edge, while at the other pocket edge there is a larger clearance between the geometric triangle and the plates.

PRESENTATION OF THE INVENTION

Based on this prior art, the present invention seeks to provide a container of the type mentioned, which can be produced particularly economically simple.

This invention is given by the features of claim 1. Meaningful developments of the invention are the subject of subsequent claims.

The container according to the invention for storing a geometric triangle has at least one spacer, which is arranged in the region of at least one of the two pocket edges. The pocket edge runs along two edges of the plates and leaves the pocket opening free. By the at least one spacer, the two plates are firmly connected to each other in such a way that the at least one spacer is fastened with its one edge to one plate and at the other, opposite edge .des at least one spacer, a fastening strip is present. This attachment strip can be attached to the other of the two plates. In this case, the catheter length of the former plate including the spacer and the fastening strip is greater than the catheter length of the other plate without spacers.

Thus, only two plate parts - the fastening strip and the plate - are attached to each other, which is possible by simple and secure fastening means and thus enables an economically favorable production. In contrast, for example, in a container according to the DE 20 2006 012 638 U1 the two plate parts and the flap, so a total of three parts are stacked in a stacked position to each other, which regularly requires two - outgoing from both outer sides of the relatively thick, three-lobed stack - separate attachment operations.

Advantageously, the attachment of the fastening strip on the other plate is such that the two longitudinal edges of the plate and the fastening strip are aligned with each other. Due to the resulting possibility of simple and exact positioning of the two fixing components a rapid and thus economical production is possible.

Preferably, the at least one spacer may be integrally connected to the one plate. The spacer can attach in particular via a line of weakness on one plate. Also, the fastening strip may be integrally connected to the spacer. The fastening strip can likewise be attached to the spacer via a weakening line.

The container can thus be made from a single strip of flat material without the need for several different components. This allows a particularly favorable and rapid production, which is economically advantageous. In addition, as inaccuracies in positioning several different components can be avoided.

The attachment of the fastening strip to the other plate can preferably be done by riveting or via a weld or an adhesive seam. This welded connection can be made by an ultrasonic welding or by a laser welding or other, the plastic from which such containers are preferably made, adapted connection technology to connect the two plates thermally firmly together. The weld may be formed, for example in the form of multiple welds, which are distributed over the entire length of the attachment strip available. The number and size of the welds can be adapted to the size of the container. In a container for a geometric triangle with a hypotenuse length of 16 centimeters, the weld may for example comprise between 15 and 20 weld points, provided that the weld seam is formed along the hypotenuse of the container.

In a preferred embodiment, a second spacer may be present between the two plates. This second spacer is arranged in the region of the other pocket edge and connects the two plates as well as the first, above-described spacer firmly together.

The second spacer can be constructed as well as the first spacer described above. In this case, the container could be constructed of two different components. Alternatively, the second spacer may also be a simple additional plate strip which is present between the two plates and integrally connected by two lines of weakness to these two plates. Thereby, the container can be made of a one-piece blank, which makes assembling the container particularly easy. So only the additional plate strip with the attached plate to the other plate must be turned over and then the fastening strip and the plate are firmly connected.

In a particularly preferred embodiment, the mutual distance between the two plates covering the base surfaces of the geometric triangle near one pocket edge may be smaller than the corresponding distance near the other pocket edge.

In this case, the smaller distance of the thickness of the geometric triangle can be adjusted so that the geometric triangle frictionally in the area near the one pocket edge in the container is stable and the greater distance of the thickness of the geometric triangle is adjusted so that the geometric triangle without frictional in the area next to the corresponding other Täschenrand is positioned in the container. The different spacing between the two plates can be achieved, for example, by arranging the spacer attached to one plate at an angle to the plane of the other plate. The plates themselves could be aligned approximately parallel in this case.

In this way, a geometric triangle inserted between the plates adjacent to the one pocket edge can be frictionally held between one of the plates and the opposite spacer, while at the other pocket edge there is a larger clearance between the geometric triangle and the plates. The triangular-shaped container with one of its triangular points pushed into the triangular-shaped container geometry triangle is only when it is almost completely pushed into the container, held by the plate and the opposite spacer, from above and below, frictionally clamped. Even a slight extraction of the geometric triangle from the container solves this frictional grip, with the Result that the geometric triangle can be easily pulled out of the container completely. Conversely, the geometric triangle can also be pushed into the container easily and without great effort and only in the last required displacement force must be spent in the remaining insertion of the geometric triangle, namely to overcome the existing frictional resistance between the geometric triangle and the two plates. This largely possible without frictional resistance pushing in and pulling out of a geometric triangle in such a container also protects the surfaces of the geometric triangle. As a result, the labels and imprints present on the surfaces of the geometric triangle can not be scratched or rubbed off.

As shown in the exemplary embodiments, this different spacing can be achieved by providing different spacers between the two plates in the respective pocket edges.

In order to be able to push such geometric triangles in such a container, which are provided with a transversely standing handle, a slot recess can be provided in the one of the two plates. The slot can then be shaped so that the geometric triangle can be pushed with its handle along the slot in the container.

It is advisable to arrange the slot parallel to that pocket edge at which the two container plates have the comparatively greater distance. The insertion can then take place without frictional resistance along this edge. Only then, when the geometric triangle is almost completely pushed in, the frictional resistance occurs due to the jamming system of the geometric triangle between the two plates.

As already stated, the container and thus the plate material preferably consists of semi-rigid, flexible plastic material. However, the plastic material and thus the individual plates of the container need not be completely rigid.

Further advantages and features of the invention can be found in the claims further specified features and the following embodiments.

WAYS FOR CARRYING OUT THE INVENTION

A container 10 made of a plastic strip of material serves to receive a geometric triangle 12. The container 10 has two basically triangular plates 14 and 16, which are integrally connected to one another via a plate strip 18 present between them.

Between the plate strip 18 and the plate 14 is a line of weakness 20 and between the plate strip 18 and the plate 16, a line of weakness 22 is formed. The weakening lines 20 and 22 extend in the present example case along one of the two catheters of the two triangular plates 14, 16. The plate strip 18 thus acts in a container according to the invention as a spacer between the two plates 14, 16th

On the plate 14, two cantilever plate parts 24, 26 are present in the present example case, leaving between them a recess 28 with a semicircular base 30 free. In the plate member 24 and in the plate member 26 is a hole 32 and 34, respectively. These two plate parts 24, 26 could not be present in a container according to the invention.

The two holes 32, 34 in the two plate parts 24, 26 have such a mutual distance that they can reach through the clip gripper a hole mechanics of a folder. The container 10 can thus be stored permanently embedded with embedded geometry triangle 12 in a folder. Through the hole mechanism is also prevented that the geometric triangle 12 can fall out of the container 10 out.

The plate 14 has, without its plate parts 24, 26, a rectangular triangular base area, which corresponds to the base area of the geometric triangle 12. While the plate parts 24, 26 are cantilevered on one of their catheters, the plate strip 18 hangs integrally on its other catheter via a weakening line 20.

The plate 16 has as well as the plate 14 has a base area which corresponds substantially to an isosceles, right-angled triangle. In the present example case, the spacer 40 in the form of a further plate strip hangs integrally on the plate 16 in one piece via a weakening line 42 extending along the hypotenuse. At the edge of the spacer 40 opposite the weakening line 42, a fastening strip 44 also hangs in one piece via a weakening line 46. The lines of weakness 42 and 46 in the present example run parallel to each other.

In the plate 16 is also a recess 48 with a semicircular base 50 is present. The recess 48 differs from the Recess 28 in that it does not engage as deep into the plate 16, as is the case with the plate 14. Namely, in the region of the recess 48 are not the two plate parts 24, 26 comparable plate parts available. In the folded state of the two plates 14, 16 are the two recesses 28, 48 with their reasons 30, 50 aligned one above the other. Through the two recesses 28, 48, an inserted into the container 10 Geometry triangle 12 can be easily grasped with your fingers and pulled out of the container 10 again without having to manually expand the pocket opening of the container.

From the in Fig. 2 apparent cutting is done by turning the plate 16 on the plate 14 and then welding the container in the region of the fastening strip 44 in Fig. 1 In the present example case, a weld seam in the form of a plurality of welding points 54 mounted at a constant distance from one another runs centrally along the fastening strip 44. By means of these welding points 54, the two plates 14, 16 are firmly connected to one another in the region of their hypotenuse. In the region of one of its two catheters, the plate strip 18 forms the firm connection between the two plates 14, 16.

In contrast to the exemplary embodiment illustrated here, a plate strip comparable to the plate strip 18 could also be present between the respective hypotenuses of the two plates. In this case, the spacer according to the invention including the fastening strip would be present along one of the two catheters of one of the two plates.

The weakening line 46 was made from the later inside of the container 10 forth, the weakening line 42, however, was made from the later outer side of the container 10 ago. Accordingly, the weakening line 42 is in a plan view according to Fig. 2 not directly visible, since the later outside of the container 10 in Fig. 2 represents the underside of the strip of flat material.

The width 60 of the plate strip 18 causes the distance D2 in the interior of the container 10 in the region of the plate strip 18 (FIG. Fig. 3 ). In the area of the welding points 54, the two plates 14, 16 are so firmly together connected, that the two longitudinal edges 56, 58 of the plate 14 and the fastening strip 44 are aligned over each other. In the folded state of the two plates 14, 16 results in an oblique, not to the plates 14, 16 parallel alignment of the spacer 40 (FIG. Fig. 3 ). The catheter length K16 of the plate 16 including the spacer 40 and the Befestigungsstreifesn 44 is namely greater by the amount 59 than the catheter length K14 of the plate 14. The spacer 40 thus has a linearly increasing distance between almost zero and D2 to the plate 14 (FIG. Fig. 4 ). A geometric triangle 12 having a slightly smaller thickness D2 to D2 is thus held only somewhere in the region of the spacer 40 between this spacer 40 and the plate 14.

Since the width 60 of the plate strip 18 is greater than the thickness 70 of the geometric triangle 12, there is a free space between the geometric triangle 12 and the two plates 14, 16. The in the container 10 completely eineingende geometry triangle thus has in the region of the two plates 14, 16 air between them and the two plates 14,16.

In the fully seated state of the geometric triangle 12 in the container 10 is in the present example, the hypotenuse 62 of the geometric triangle 12 in the region of the spacer 40 and there is clamped between the plate 14 and the spacer 40 fixed. By contrast, in the fully inserted state, the two cathodes of the geometric triangle 12 lie in that region of the container in which the two plates 14, 16 are arranged approximately parallel to one another, with air between the two plates 14, 16. The geometric triangle 12 is therefore in the region of Spacer 40 held clamped. In the area of the plate strip 18, however, the geometric triangle 12 is not held in a clamping manner.

The plate parts 24, 26 also form a certain guide for the insertion of the geometric triangle 12 into the container 10. Thus, the geometric triangle 12 can to a certain extent be placed on the plate part 24 or 26 by means of its front dipping into the container 10 triangle tip and then guided as it were guided into the pocket opening 68 of the container 10. The container 10.5 according to Fig. 5 differs from the container 10 by the arrangement of the spacer 40.5. The spacer 40.5 is significantly narrower than the spacer 40 and arranged approximately at right angles to the plane of the plates 14, 16. In the present example, the plates 14, 16 are arranged parallel to each other, so that the geometric triangle 12 is kept clamped at any edge.

In contrast, the plates 14, 16.6 in the container 10.6 according to Fig. 6 not arranged parallel to each other. In the container 10.6 has been dispensed with a plate strip 18 comparable plate strip between the two plates 14, 16.6; the plates 14 and 16.6 therefore depend directly on a line of weakness 72 together. As a result, the distance in the region of the spacer 40 is so great in relation to the thickness 70 of the geometric triangle that the latter geometric triangle 12 is not clamped by the spacer 40 but by the inclined plate 16.6 together with the other plate 14. Thus, a stored geometric triangle 12 in the envelope area of the two plates 14,16.6 are clamped, while in the region of the spacer 40 air between the plates 14, 16 and the geometric triangle is present.

In contrast to the exemplary embodiments illustrated here, a spacer comparable to the spacer 40 can also be provided on both pocket edges of a container according to the invention. The container according to the invention would be constructed in this case from at least two strips of flat material.
