Description

The invention relates to an adhesive tape dispenser in a compact form with a housing, which comprises a first housing shell and a second housing shell, which are formed as two separate components and assembled form the housing, and with an at least partially arranged in the housing receiving means for rollable receiving a roll of adhesive tape wherein the receiving device comprises an axis for receiving the adhesive tape roll.

In principle, dispensers for adhesive tape rolls, also called "dispensers", serve the user as a storage container for the adhesive tape rolls themselves and as an application aid for their processing. The main purpose of a tape dispenser is the simple, easy and clean unrolling and cutting of strips of tape in the required length.

Therefore, such devices for dispensing adhesive tape are designed for a user, wherein the adhesive tape roll is received by the receiving device, which comprises an axis, in such a way that the adhesive tape roll can be unrolled by a user. Furthermore, the known devices normally have a tear-off aid, in particular a blade, which serves for tearing off an adhesive tape section which has been unwound from the adhesive tape roll.

Adhesive tape dispensers are basically available in several embodiments, including dispensers with film storage, in which the adhesive film in the rest position with the adhesive side on a film storage surface, which is directly adjacent to the demolition blade or the demolition blade sticks. Here, the film is gripped by a user with his fingers between the shelf and film roll, unrolled and then pulled with the adhesive side (side) over the knife, so that the desired tape section is cut off and the remaining piece of tape stuck back onto the shelf.

From such manual dispensers, there are, on the one hand, relatively large and heavy variants with a housing for placement on a table top or the like. Furthermore, there are compact hand-held dispensers in which the housing is only slightly larger than the film reel itself. Such adhesive tape dispensers in compact form, as claimed by the present invention are therefore easily portable by a user and very easy to handle. The Kompaktroller are compared to the scooters much easier.

Kompaktroller are often constructed such that the housing into which the roll of adhesive tape is introduced, consist of two separate items, the so-called housing shells. The housing shells can basically have any shape, as long as they form the housing together. This ensures that the housing can be opened with a new roll to fill the adhesive tape hand-held dispenser. This is often accomplished by having the housing comprise two shells that can be disassembled along a parting line that is often perpendicular to the reel plane. In this case, then have one of the two shells or both shells on a receiving device in the form of an axis on which the role plugged or on which the role can be arranged.

In known Kompaktrollern often occurs the problem that the two housing shells are relatively firmly connected together and thereby difficult for a user to separate from each other if he wants to insert a new roll of adhesive tape. In other known embodiments in which the shells are composed only very loose and therefore are easy to separate from each other, however, there is often the risk that the two housing shells inadvertently separate or separate from each other and the adhesive tape roll can slip out. Finally, there are other embodiments in the prior art, in which for the Öffenbarkeit and closeability of the two housing shells very complex and costly constructions, such as hinges are needed.

The invention is therefore an object of the invention to provide an adhesive tape dispenser of the type mentioned, which is easily and conveniently opened by the user to replace the roll of adhesive tape and at the same time a secure closure of the housing offers, wherein the adhesive tape dispenser should be easy and inexpensive to produce.

This object is achieved with an adhesive tape dispenser in compact form with the features of claim 1 of the present invention.

The core idea of the present invention consists in the fact that the axis of the receiving device consists of a first and a second axle stub, wherein the first axle stub is disposed on the first housing shell and the second axle stub on the second housing shell. The term axle stub is to be understood in each case an axle part or axle section of the axle, wherein the two axle stubs are to be designed such that they can be inserted into one another and, in an assembled state of the housing, form the axle of the receiving device. For this it is necessary that at least one of the two axle stems, namely that axle stub which forms the outer axle stub in the assembled state, is hollow. Preferably, however, both axle stubs are designed as a hollow-axle stub, whereby a total of material and weight can be saved thereby. It is advantageous here that the two axle stubs act as centering aid when bringing together the two housing shells, so that the merging is simplified for the user. Furthermore, a fastening means for fastening the two parts together is provided on the first and / or on the second axle stub. Such a configuration is simple and inexpensive to manufacture and for the user, the housing shells are easy and convenient to merge or disassemble. By the fastening means a secure closure or cohesion between the two housing shells is achieved. Depending on the configuration of the fastening means, this may be formed on the first or on the second axle stub or on both. The axle stubs are often expediently designed such that they protrude approximately perpendicularly from a housing wall of a housing shell.

Preferred embodiments of the invention are characterized in the subclaims.

Conveniently, the inner diameter of that axle stub which forms the outer axle stub of the axle in the assembled state, in such a way to the outer diameter of that axle stub, which in the assembled state, the inner Achsstutzen the axis forms, adapted that adjusts a substantially play-free installation of the two axle stub to each other. In this embodiment, the Achsstutzen the Zusammenführvorgang the two housing halves or when disassembling the same act as a guide, as specified by the play-free system exactly how the two housing halves are to be brought together. This further improves handling for the user.

In principle, the fastening means may be any known from the prior art and suitable for this fastening means. In a preferred embodiment, the fastening means is designed as a latching connection. For this purpose, it is expedient to provide a latching means on one axle stub and, on the other axle stub, a corresponding counterpart in which the latching means can engage. This results in a reliable and secure connection of the two housing shells together, which can be easily solved again and is easy to manufacture.

Furthermore, it is preferred if the fastening means comprises at least one groove, which is provided on one of the two axle stubs and at least one nose corresponding to the groove, which is provided on the other of the two axle stubs. The groove is expediently designed such that the nose can be inserted into it and guided in it. The guidance of the nose in the groove during the Zusammenvorgangvorganges the two housing shells provides for further improved handling such that it is ensured that the two shells are assembled at the correct angle to each other and in the right place by the user. The nose is expediently designed as protruding from the axle stub, cam o. The like. Formed. Conveniently, the nose protrudes in the radial direction of the axle stub. In addition, a detent recess may be provided in the groove, which is designed to engage the at least one nose. Conveniently, this locking recess is provided on the outside of the housing shell facing the end of the groove. This ensures that the nose is guided during the Zusammenführvorgang the at least two housing shells in the groove and engages upon reaching its end position in the locking recess of the groove. As a result, a secure closure of the two housing shells is achieved in a simple manner. The detent recess and the nose are to be dimensioned such that the user has to overcome a certain resistance until he can divide the two housing shells. In this embodiment, it is particularly expedient, the shells together with the groove provided therein or

Produce plastic nose to ensure a certain flexibility of the material when snapping or disengaging the nose in or out of the detent recess.

Furthermore, it is preferable to design the groove such that the housing can be opened by rotating the first and the second housing shell relative to each other. Conversely, in this embodiment, by rotating the housing shells in the opposite direction, the housing can be closed. As a result, the handling of the user is further simplified because it can open the housing by simply rotating the two housing parts against each other.

In particular, a rotation of the housing shells against each other during the opening process can be achieved in that the groove at an angle, in particular an angle of 30 ° to 60 °, preferably from 40 ° to 50 °, particularly preferably 45 °, to the longitudinal axis of the axis of the receiving device runs. This results from a simple design of the fastener a konfortabler opening mechanism for the user.

Furthermore, the handling in this embodiment is further improved by the fact that, for an opposite rotation of the two housing shells to the opening of the housing on a narrow side of each housing shell a handle region is arranged in each case for at least one finger of the user. Furthermore, these grip areas of the two housing shells are advantageously arranged adjacent to one another. This supports the twisting process. Expediently, the narrow sides are in this case those sides which run essentially perpendicular to the adhesive tape roll plane. The grip areas can have any suitable shape. In particular, the surface can be structured there, so that slippage of the fingers of a user is avoided. Furthermore, the grip areas can also be widened in the way that secure access by the user is possible.

In a further preferred embodiment of the invention, the fastening means is designed as a bayonet closure. For this purpose, it is expedient to likewise provide a groove on one of the axle stubs, which extends approximately parallel to the longitudinal axis of the axle of the receiving device. At the outside end of this groove, a suitably relatively short transverse groove connects, in which a nose o. The like., Which is arranged on the other axle stub, can be guided into it for locking purposes.

In a further preferred embodiment, a thread is provided as a fastening means, wherein on the outer circumference of the inner axle stub a thread and on the inner circumference of the outer axle stub a corresponding mating thread is provided. As a result, the two axle stubs can be screwed together.

Furthermore, it is expedient to provide a stop in the inner axle stub to limit the insertion depth of the inner axle stub in the outer axle stub. This ensures that the two housing shells are always in the same position relative to each other in the closed position.

Fig. 1 shows the perspective side view of a tape dispenser 100 in compact form. The adhesive tape dispenser comprises a housing 10, which in turn consists of a first housing shell 10a and a second housing shell 10b. The housing 10 is in the closed state, that is, the two housing shells 10a, 10b are assembled and fastened together to form the housing 10. The two housing shells 10a, 10b are formed corresponding to each other in such a way that they fit directly to each other. Each shell 10a, 10b has a side wall 11, which is aligned in each case approximately parallel to the roller plane of an adhesive tape roll 12 inserted into the housing 10. Each housing half 10a, 10b has in regions a narrow side wall 13a, 13b in the region of the narrow side of the housing 10. In a transition region 14 are the narrow side walls 13a, 13b of the first Housing half 10a and the second housing shell 10b viewed in the transverse direction of the housing directly next to each other. In the transition region 14, the two narrow side walls 13a, 13b are separated by a parting line 15 running obliquely to the roller plane. For each side of this parting line 15, a grip region 16a, 16b is formed in each case, so that the two grip regions 16a, 16b lie directly next to one another or directly above one another. The grip portions are configured to provide sufficient space for a user to place one of his fingers, such as a thumb, on each of them. The grip regions 16a, 16b are each formed by a region of the side wall 13a, 13b. Arrow markings 17a, 17b in the grip areas 16a, 16b indicate to the user in which direction the respective housing shell 10a, 10b has to be rotated in order to open the housing 10. The housing 10 has a foot region or bottom region 18, in which the narrow side wall 13a, 13b is planar and thus provides a footprint for the housing 10, for example on a table top or the like. The adjoining the foot area 18, rear narrow side wall is formed bent and ends in an upwardly projecting area. At this upwardly projecting area a tray 19 for an adhesive tape and an adjoining blade 20 for separating an unrolled from the roll 12 tape strip is arranged. Below the storage area 19, an opening 21 is provided in the narrow side of the housing 10, through which an adhesive tape strip 12a unrolled from the adhesive tape roll 12 can be led out through the housing 10 and placed on the storage area 19. The length of the opening 12 corresponds approximately to two-thirds of the diameter of the adhesive tape roll 12 and extends over the entire width of the housing 10. Thus, there is sufficient space for a user to guide the tape strip 12a out of the housing 10 and sever it by means of the blade 20.

In a central region of the side wall 11 of each housing shell 10a, 10b, an inwardly projecting into the housing interior axle nozzle 22a, 22b is arranged. Both axle stubs 22a, 22b are each designed as a hollow axle stub. In the assembled state of the housing 10, the two axle stoppers 22a, 22b are plugged into each other, wherein the axle stub 22a forms the inner axle stub and the axle stub 22b the outer axle stub and both axle stubs together form an axis which acts as a receiving device and the adhesive tape roll 12 can be pushed or attachable. Since the axle stub 22b forms the outer stub of the axle, the adhesive tape roll 12 is thus in direct contact with the outer axle stub 22b.

Fig. 2 shows the presentation Fig. 1 , wherein the two housing halves 10a, 10b according to the markings 17a, 17b have been rotated against each other. The direction of rotation of the individual housing shells 10a, 10b is illustrated in each case by the arrows 23a, 23b. By the opposite rotation, the fastening means, which is arranged on the two axle stoppers 22a, 22b, released, and the two housing shells 10a, 10b can be removed from each other. At the same time, the fastening means is designed such that, due to the opposite rotation of the two housing shells 10a, 10b, they move away from one another in the direction perpendicular to the roller plane. In other words, the two housing shells 10a, 10b are moved apart by the mutual rotation along the longitudinal axis of the axle stubs 22a, 22b. When the axle stub 22a of the first housing shell 10a has been completely unscrewed or removed from the second axle stub 22b of the second housing shell 10b, the housing shell 10a can be completely removed from the housing shell 10b. Now a user has access to the adhesive tape roll 12 and can replace it, for example.

In the Fig. 3 and 4 Now, the fastening means, which is designed for fastening the two housing shells 10a, 10b and is arranged on the axle nozzle 22a, 22b, explained in more detail. Fig. 3 shows a perspective top view of the inside of the housing shell 10 a and Fig. 4 a perspective top view of the inside of the housing shell 10b. In Fig. 3 It can be seen that in the outer casing of the axle nozzle 22a of the first housing shell 10a is formed a straight line and obliquely to the longitudinal axis of the Achsstutzens 22a groove 24 is formed. On the opposite side of the Achsstutzens 22a another, identical groove is provided (not shown here). The groove 24 extends from the upper edge of the Achsstutzens 22a over approximately two-thirds of the height of the Achsstutzens 22a and ends in a circular detent recess 26. On the inner surface of the Achsstutzens 22b of the second housing shell 10b designed as a protruding from the jacket, round knob nose 25 is provided , The nose 25 is formed such that it can slide through the groove 24 and engages in the locking recess 26. By snapping the two housing halves 10a, 10b are releasably connected together. The fastening means is therefore a guided latching connection. Due to the inclination of the groove 24 relative to the longitudinal axis of the axle stub 22a, 22b, the nose 25 is unscrewed from the groove 24, so that in an opposite rotation of the two housing shells 10a, 10b, the two housing shells 10a, 10b also in the longitudinal direction of the axle stub 22a , 22b are moved apart.

The nose 25 opposite a further identical nose is formed (not shown here), which engages in the second groove 24.

On the housing shell 10a facing region of the Achsstutzens 22a designed as a circumferential, from the axle stub 22a outwardly projecting ring stop 27 is provided. As a result, the insertion depth of the axle nozzle 22a in the axle nozzle 22b can be limited to a predetermined extent.
