EP3564167B1 - Tape dispenser, in particular dispenser for adhesive tape - Google Patents

Description

The invention relates to a tape dispenser, in particular in the form of an adhesive tape dispenser, according to the preamble of claim 1. Such a tape dispenser is from US Pat DE 199 83 151 B4 known.

In the case of such tape dispensers, very complex housing designs are often common which, in addition to storage for the tape reel, in particular adhesive tape reel, include feeds to removal areas and separating devices.

In contrast, the object of the present invention is to create a tape dispenser, in particular in the form of an adhesive tape dispenser, of the type specified in the preamble of the claim, the construction of which is simple to manufacture, which is technically simple to operate and reusable.

This problem is solved by the features of claim 1.

In detail, a tape dispenser is created, which is designed in particular as an adhesive tape dispenser. Such an adhesive tape is usually applied to an adhesive tape reel and stored in the tape dispenser by means of the reel. For this purpose, the tape dispenser according to the invention has a tape reel receiving area which is formed by two unwinding parts which can be plugged into one another and which has a cylindrical guide surface for the tape reel. The two unwinding parts, which can also be referred to as housing parts of the unwinding device, are fixed to one another by means of a detachable fastening device. In order to be able to store the tape reel in a simple manner, the tape dispenser according to the invention has a retaining ring protruding beyond the guide surface on each of the end edges of the guide surface. This means that the guide surface is surrounded on its two end faces, i.e. at a distance from one another, by the two retaining rings which protrude beyond the guide surface so that a tape reel arranged on the guide surface is held captive and technically simple and easy to use.

The tape dispenser according to the invention comprises a plurality of webs which are arranged on the first dispenser part of the two dispenser parts and which are provided with locking lugs at their free ends. In the fixation state of the two unwinding parts, these locking lugs engage in locking recesses which are arranged on the second unwinding part. In the fixed state, the tape dispenser according to the invention holds the tape reel freely rotatable via its receiving area through a free space between the receiving area and the tape reel, so that the tape reel can be rotated freely for removing tape sections, in particular adhesive tape sections, so that in a simple and easy-to-use manner and One-handed operation is possible. If the first roll-off part is pushed into the second roll-off part with its webs, the webs are slightly deformed inward and, as soon as they have reached their end position, the locking lugs can snap into the catch recesses and connect the two roll-off parts with one another.

If the unwinding parts are to be separated from one another after the stored tape has been emptied, the latching tongues only have to be lifted out of the latching recesses by applying slight pressure so that the first unwinding part can then be pulled out of the second unwinding part. The tape dispenser according to the invention can then be filled again and transferred to the fixing position or operating position.

The subclaims contain advantageous developments of the invention.

In summary, it should be noted that the two-part construction according to the invention described above represents a core that can be used for rolls of tape, in particular rolls of adhesive tape, which have, for example, a depth of 30 mm or 50 mm, with other depths or widths of the tape rolls naturally also being adjusted accordingly of the tape dispenser according to the invention are possible. In the inserted state of the roll of tape, as described above, the guide surface is at a small distance from the core or the reel of the tape, in particular adhesive tape, so that the inserted core in the form of the tape dispenser according to the invention is free-running. With one-handed operation, this insert therefore serves as a practical dispenser. Due to the two-part construction, the tape dispenser according to the invention can be reused. Both dispenser parts are simply pushed in from the outside until they snap into one another. This creates a great handling advantage, especially for stage technicians, craftsmen and other professional areas in the event industry.

one the Fig. 1 and 2 Corresponding perspective illustration in a fixation or operating state of the tape dispenser according to the invention, that is to say in a fully assembled state of the tape dispenser.

From a synopsis of the Figs. 1 to 3 the function of a tape dispenser 1 according to the invention results in a sequence in which in Fig. 1 two dispenser parts 3 and 4 are arranged at a distance from one another, Fig. 2 shows a state in which the first unwinding part 3 is already partially inserted into the second unwinding part 4 and in Fig. 3 a state F in which the two unwinding parts 3, 4 are completely inserted into one another and fixed to one another, so that the fixing state F simultaneously represents the operating state of the tape dispenser 1 according to the invention. This operating or fixing state F is indicated by the letter "F" in brackets after the indication " Fig. 3 "symbolizes.

The tape dispenser 1 has a tape reel receiving area 2. The tape reel or adhesive tape reel, if the tape is an adhesive tape, is a core or ring on which the tape is wound and which must be stored by rotating on the receiving area 2 during the operating state F in order to remove the tape.

As can be seen from the Figs. 1 to 3 results, the tape reel receiving area 2 is formed by two plug-in unwinding parts 3, 4, which can also be referred to as housing parts 3, 4 of the tape dispenser 1 according to the invention. The receiving area 2 results only in the final assembled state according to FIG Fig. 3 , however, corresponds in its width to the cylindrical guide surface 5, which in the fixed state F according to FIG Fig. 3 is limited by two retaining rings 9 and 10, which are each arranged on the end edges 7, 8 of the guide surface 5. In this in Fig. 3 For example, an adhesive tape is arranged on the tape dispenser 1 and held captive and freely rotatable.

The ones in the Figs. 1 to 3 The illustrated particularly preferred embodiment of a detachable fastening device 6A, 6B for fixing the two unwinding parts 3, 4 has a plurality of webs 11, 12, 13, in the example a number of three webs that are arranged at an angular distance of 120 ° from one another. These webs 11, 12, 13, which are arranged on the first unwinding part 3, have locking lugs 14, 15 and 16 at their free ends 17, 18 and 19 respectively. In the fixed state F, which is shown in Fig. 3 is shown, these latching lugs 14, 15 and 16 engage in latching recesses 20, 21 and 22 correspondingly arranged on the second roller part 4. This means that the locking recesses 20, 21 and 22 in the example are also arranged at angular intervals of 120 ° on the second unwinding part 4 and their dimensions and alignment are adapted to the dimensions and alignment of the locking lugs 14, 15 and 16.

The latching recesses 20, 21 and 22 are here arranged in an end face 23 of the second unwind part 4 or thus in an end face of the retaining ring 10.

As the Figs. 1 to 3 Furthermore, it is clear that the second unwinding part 4 has an inner circumferential wall 24 in which guide channels 25, 26 and 27 extending from the locking recesses 20, 21 and 22 respectively extend.

In addition to the retaining ring 9, the first unwinding part 3 has a guide ring 28. This guide ring 28 is aligned, at least essentially, in particular exactly perpendicular to the retaining ring 9.

As can also be seen from the Figs. 1 to 3 results, the webs 11, 12 and 13 are arranged on the guide ring 28, which results in the advantage of a very precise possibility of introducing the first unwind part 3 into the second unwind part 4. Because in the fixation state F, the guide ring 28 engages flush with an associated guide groove 29 of the inner peripheral wall 24, with guide channels 25, 26 and 27, which each extend from the locking recesses 20, 21 and 22 in the inner peripheral wall 24, the same depth as the Have guide groove 29 and open into this. This construction results in the constellation shown in Fig. 3 is shown, in which, as explained above, the tape dispenser 1 according to the invention forms a tape reel receiving area 2, which is formed by the two described plug-in dispenser parts 3, 4 and has a cylindrical guide surface 5, which at their end edges 7, 8 each from the previously described retaining rings 9 and 10, which protrude beyond the guide surface 5, so that an inserted tape reel (or generally tape reel) can be held captively by the tape dispenser 1, but can be operated freely rotatable.

The material of all of the components described above is preferably plastic, with all of the components being able to be connected to and detached from one another without the use of special tools.

In addition to the above written disclosure of the invention, this explicitly refers to the graphic representation of the invention in FIGS Figs. 1 to 3 Referenced.
