Description

The invention relates to a dispenser for adhesive film (as "adhesive or Filmabroller") with a base unit and a dispenser unit for film or adhesive film, wherein the dispenser unit has a receptacle for a roll for adhesive film and a knife for cutting the film, wherein the base unit a Stand for positioning (also setting up) on a substrate and a receptacle for the dispenser unit.

Adhesive film dispensers according to the prior art can be distinguished in table dispenser on the one hand and hand dispenser on the other. Table dispensers are because of their usually relatively high weight firmly on a table or other suitable surface, which allows in the best case one-handed operation of the device and a one-handed removal of adhesive film strips. However, because of their shape and weight, table dispensers are only conditionally suitable for use as hand dispensers since they are relatively difficult to handle. Hand dispensers, on the other hand, are light and flexible and can therefore be used in many areas without great restrictions. However, they have the disadvantage that a one-handed operation as a desktop device is almost impossible and always both hands are needed for removal of adhesive film. Examples of typical table devices are from the US 6,688,549 B1 as well as the FR 1449 157 known. Examples of a hand dispenser are from the DE 101 18 996 A1 as well as the DE 20 2007 011402 U1 known.

FR 1449 902 visualizes a table dispenser, in which a, an adhesive tape roll enveloping cartridge is inserted into a dispenser. The cartridge with the adhesive tape roll is interchangeable and has a slot from which the adhesive tape is led out of the cartridge and, when the cartridge is inserted into the dispenser, is fed to a knife arranged on the dispenser for separating off adhesive tape sections.

The object of the invention is to provide a dispenser which reduces or even avoids the aforementioned disadvantages. In this case, a dispenser is to be created, which offers a user the ability to film or adhesive tape both one-handed or tied to a desk or a pad (as in a table dispenser) as well as with high flexibility in different places job-unbound or no way that To shut off, remove and apply the device. It is a further object to provide a flexible roll-off for film or adhesive film in which the film or adhesive film and / or the associated role is covered when not in use against the environment and protected from contamination.

These objects are achieved with an invention by a dispenser with a base unit and a dispensing unit for adhesive film, wherein the dispenser unit has a receptacle for an adhesive film roll and a knife for cutting the adhesive film, wherein the base unit has a base for positioning on a substrate and a receptacle for the dispenser unit, wherein the dispenser unit for use as a hand dispenser from the receptacle of the base unit is removable and is arranged for use as a stand-off in the receptacle of the base unit (claim 1).

They are achieved with a further invention by a dispenser with a base unit and a dispensing unit for adhesive film, wherein the dispenser unit has a receptacle for an adhesive film roll and a knife for cutting the adhesive film, wherein the base unit has a base for positioning on a substrate and a receptacle for the dispenser unit, wherein the dispenser unit is rotatable in the receptacle of the base unit between a first functional position in which the adhesive film is peelable by a user from the adhesive film roll and detachable by means of the knife, and a second functional position, in which the adhesive film and the knife opposite the environment and the user are covered (claim 2).

They are achieved with a still further invention by a dispenser with a base unit and a dispensing unit for adhesive film, wherein the dispenser unit has a receptacle for an adhesive film roll and a knife for cutting the adhesive film, wherein the base unit has a base for positioning on a substrate and a receptacle for the dispenser unit, wherein the dispenser unit for use as a hand dispenser from the receptacle of the base unit is removable and is arranged for use as a stand dispenser in the receptacle of the base unit, wherein the dispenser unit in the receptacle of the base unit between a first functional position, in which Adhesive film by a user from the adhesive film roll peelable and can be separated by means of the knife, and a second functional position is rotatable in which the adhesive film and the knife against the environment, especially the user are covered (claim 3).

The positioning on the ground is also to be understood as a pure placing on the underground.

The claimed method for operating a unwinder for film, in particular adhesive film according to one of claims 1 to 3 is a working method for dispensers who use film as a carrier in order to apply a commodity, such as adhesive or Abdeckweiss or color from a surface can.

The abovementioned dispensers advantageously combine positive properties of table dispensers with those of manual dispensers. The dispenser unit can be used as a handheld device or alternatively arranged in the base unit as a tabletop device. The base unit not only serves a high stability and skid resistance when used as a table dispenser, but advantageously forms a receptacle in which the dispenser unit when not in use safely and easily retrieved and, if necessary, can be closed. In this way, the film, adhesive film and the associated role when not in use of the dispenser unit are protected from the environment and from contamination.

The base unit and / or the dispenser unit are designed in one embodiment of the invention (s) as plastic injection molded parts. According to another embodiment, the base unit and / or the dispenser unit are made of cast metal or consist essentially of an amorphous metal alloy, in particular those known by the name LiquidMetal or Vitreloy, or of a thermoplastic, e.g. Liquid Wood. These are trademarks for amorphous metal alloys (so-called metallic glasses) developed by Liquidmetal Technologies. Due to their non-crystalline structure, the zirconium alloys used are more resistant and resilient than alloys of titanium or aluminum used in the same areas. An example of the composition of an alloy (Vitreloy 106a): zirconium 58.5%; Copper 15.6%; Nickel 12.8%; Aluminum 10.3%; Niobium 2.8%.

According to one embodiment of the invention, the receptacle of the base unit for the dispenser unit can be formed by a recess or in the form of a recess in the base unit. In this case, the dispenser unit can be introduced into the base unit so that it and the adhesive film contained therein are at least partially covered by the latter, depending on the position of the dispenser unit relative to the base unit. The dispenser unit itself need not be provided with special means for protecting the adhesive film, but can be tailored to their function as a hand-held dispenser as easy as possible and easy to handle on the user side. The base unit, however, which should be designed with high weight and not necessarily easy to handle, can be designed as a cover without significant restriction in terms of their design in particular cabinet-like. Finally, it is usually easy for a user to bring the dispenser unit handled by him into a well visible for him recess.

According to a further proposal of the invention, the dispenser unit in the receptacle of the base unit is rotatable about an axis of rotation of the roller (as a carrier of the film, this as a carrier of the product) parallel axis of rotation, in particular between the first and the second functional position. The recess of the base unit may form a stop or be formed with a stop on which the dispenser unit rests in the first functional position. Alternatively or additionally they form a (further) stop or be formed with such a, on which the dispenser unit rests in the second functional position. In this way a special simple and safe handling of the unwinder is achieved when used as a tabletop device. The dispenser unit is secured or fixed both in the removal position (first functional position) in which adhesive film can be pulled off and separated by a user, and in the closed position (second functional position) in which the dispenser is closed and no adhesive film can be removed , Between the two functional positions, the dispenser unit is advantageously easy to rotate.

According to another form, alternatively or in addition to one or both of the abovementioned stops, latching structures may be provided on the dispenser unit and on the base unit. These can block or inhibit the dispenser unit in one or both functional positions or also in intermediate further positions. The latching structures can be used as latching projections and counter-structures interacting with them, e.g. in the form of depressions or counter-projections, be formed. According to one embodiment, a latching projection is respectively formed on side walls of the dispenser unit, which cooperates in the open functional position and in the closed functional position with a corresponding latching recess in a respective side wall of the recess of the base unit.

According to a further proposal, the dispenser unit and the base unit form a pivot bearing, around which the dispenser unit is pivotable upon release from the base unit. For this purpose, the dispenser unit can have a support section, preferably in the form of an inner bearing element, which abuts at least partially against an abutment section, preferably in the form of a bearing socket of the socket unit, when the dispenser unit is in the second functional position. The pivot bearing is detachable. That is, the abutment portion is released from the abutment portion when the dispenser unit is rotated from the second operative position to the first operative position, is in the first operative position, or is completely disengaged from the base unit. The pivot bearing is engaged only when the dispenser unit is in the second operative position or is pivoted out of it until it is fully released. The pivot bearing and the bearing cup and the inner bearing element have a pivot point.

The base unit may have a groove for guiding and receiving a projection of the dispenser unit, which groove is preferably formed in side walls of the recess of the base unit. Alternatively, the dispenser unit may have a groove for guiding and receiving a projection of the base unit, which groove is preferably formed in side walls of the dispenser unit. The projection in both cases forms a pivot which is mounted in the groove, so that the dispenser unit can be rotated in the base unit between the first and the second functional position around this pivot. Trunnion and groove form a pivot bearing. The groove may be open on one side or end, ie open to the environment, and be widened on its opposite side or end to a pivot bearing receptacle for the projection of the dispenser unit.

In this case, form the pivot bearing and the projection of the pivot bearing. With particular advantage, the groove may be formed in its longitudinal direction arc segment-shaped with a curvature of the radius about the pivot point of the abutment portion of the base unit (or the pivot bearing). The radius corresponds to the distance between the groove and the pivot point. The above-described embodiment makes it possible that the dispenser unit can be rotated about the pivot bearing between the first and the second functional position and can be pivoted out of the second functional position in a further user-side pivoting operation from the second functional position to the pivot bearing. In the latter pivoting about the pivot point of the pivot bearing moves the part of the pivot bearing forming projection of the dispenser unit from the pivot bearing out through the arcuate groove in the direction of its open end out of the groove, so that the dispenser unit is detached from the base unit and easy as a hand-held device is removed and can be used.

According to a further embodiment of the invention, the projection of the dispenser unit is designed as an arc segment with a curvature of the radius around the pivot point of the bearing section of the dispenser unit.

The radii of curvature of the groove and the projection are the same size. In this way, a guided movement of the projection through the groove is possible. In order to achieve a secure mounting of the dispenser unit via the rotary bearing, the rotary bearing receptacle of the groove in the base unit is designed to be circular across the rotational axis of the dispenser unit. In this case, the diameter of the pivot bearing receptacle essentially corresponds to the length of the projection of the dispenser unit. The leadership of the projection in the pivot bearing receptacle takes place in this case over the end surfaces of the projection on the peripheral wall of the pivot bearing receptacle.

According to a further embodiment of the invention, the projection of the dispenser unit is aligned in the direction of the groove of the base unit when the dispenser unit is in the second functional position. In this way, the projection in another user-side pivoting operation can penetrate out of the pivot bearing receptacle out into the groove. Alternatively or additionally, the projection of the dispenser unit relative to the groove of the base unit may be blockingly aligned when the dispenser unit is in the first functional position. This blockage can be achieved in that the angle of rotation between the two functional positions is not equal to 180 °, preferably in a range between 170 ° and 179 ° or 181 ° and 190 °, or by a small radius, in which the projection in opposite orientation the curvature of groove and projection, as the case in the first functional position, due to its curvature can not migrate through the groove.

The Figures 1 and 2 show the dispenser 1 in its function as a table dispenser with the dispenser unit 3 accommodated in the base unit 2, namely once in a closed state ( Fig. 1 ) and once in a fully opened state ( Fig. 2 ). The FIGS. 3a and 3b show the adhesive film dispenser 1 from different viewing directions during a disengaging operation of the dispenser unit 3 from the base unit 2 to use the dispenser unit as a hand dispenser. Fig. 4 finally shows the adhesive film dispenser 1 in its function as a hand dispenser with the dispensing unit 3 completely detached from the base unit 2.

How the particular FIGS. 5 to 9 clearly visible in sectional views, the base unit 2 has a base 4. This is formed by a lower base part 5, which carries a base upper part 6 on its side opposite the base 4 side. The base upper part 6 engages in an annular groove 7 formed in the lower base part 5 and is held in this or connected via this with the lower base part 5. The base top 6 is formed as a shell-like housing and has an outer wall 28, the lower edge 29 engages in the groove 7 of the base lower part 5.

The base 4 is formed non-slip, for example by means of a rubber coating or other reibwerterhöhenden coating. In this way, adhesive film in the in FIG. 2 shown removal position, ie in the fully open state, are deducted from the dispenser 1 in function as a table dispenser, with a secure and firm state of the unwinder 1 is ensured on a standing surface, not shown in the figures without slipping. The lower base part 5 and / or the upper base part 6 are preferably designed as plastic injection molded parts.

On its side opposite the lower base part 5, the base upper part 6 is provided with a receptacle for the dispenser unit 3. The receptacle is formed by a recess 8 formed in the outer wall 28. This is open at the top and outside and is laterally on both sides by side walls 9a, 9b and on its underside, d. H. in the direction of the base lower part 5, bounded by an intermediate wall 10.

In the side walls 9a, 9b of the recess 8 an arcuate groove 11a is formed. This has a circular widened pivot bearing receptacle 12, whose function will be explained later. At its - the pivot bearing receptacle 12 opposite - the end of the groove 11a (one or both grooves) is open to the outside. It has (or have) a radius of curvature R and extends as a curved or circular arc segment spaced around the radius R about a pivot point D. In its adjoining the outer wall portion 28 is the Partition wall 10 formed to a bearing cup 19. This defines the pivot point D, about which - as will be shown later - the dispenser unit 3 is pivoted upon release from the base unit 2.

The dispenser unit 3 is designed as a partially partially hollow-cylindrical body which is partially open over a certain angular range and in the interior of which an adhesive film roll 13 can be received on an axle element 14. The dispenser unit 3 has a lateral cantilever 15, at the free end 17, a knife 16 is arranged. The free end 17 of the cantilever 15 is formed as an inner bearing element 18 and fits with the bearing cup 19 of the base top 6 together. The dispenser unit 3 is preferably designed as a plastic injection-molded part and has a curved outer wall 20 as well as orthogonally arranged and end faces of the hollow part cylinder forming side walls 21a, 21b. The side walls 21a, 21b are parallel to each other and each provided with a projection 22a, 22b. This protrudes out of the plane of the side walls 21a, 21b in the axial direction of the partial hollow cylinder and is arcuate in the plane direction of the side walls 21a, 21b. The radius of curvature of the arcuate projection 22a, b corresponds to the radius of curvature R of the arcuate groove 11a, 11b in the side wall 10 of the base top 6 and is parallel to the plane of the side walls 21a, 21b.

The shaft member 14 has a substantially cylindrical center piece 23 for receiving the adhesive film roll 13 and laterally adjoining fastening flaps 24a, b in the axial direction. As in particular the FIGS. 10a to 10f 2, the width of the center piece 23 of the shaft element 14 essentially corresponds to the width of the adhesive film roll 13. The lateral fastening flaps 24a, 24b are made of a position extending essentially in the axial direction of the shaft element 14 (shown in FIG FIG. 10b ) in a pivoted by 90 ° mounting position (shown in FIG. 10c ) pivotable. In this fastening position, the fastening flaps 24a, 24b fix the adhesive film roll 13 on the center piece 23 on the one hand and serve for a centered fastening of the adhesive film roll 13 in the dispenser unit 3 on the other hand.

The assembly of the roller 13 (hereinafter often "adhesive roll") on the axle 14 takes place as follows: The axle 14 is inserted with axially extending fastening flaps 24a, 24b in the adhesive film roll 13 (off Figures 10a and 10b ). Will the intended, in the FIG. 10b achieved position in the adhesive film roll 13, the fastening flaps 24a, 24b are pivoted by about 90 ° in the fastening position, so that they rest against the side of the adhesive film roll 13 (see FIG. 10c ). In this configuration, the adhesive film roll 13 is inserted together with the shaft member 14 in the dispenser unit 3. This process is in the FIGS. 10d to 10f shown. In the intended end position of the adhesive film roll 13 in the dispenser unit 3 engage the fastening flaps 24a, 24b with not shown in the figures locking elements of the respective side wall 21a, 21b. The Adhesive film roll 13 is rotatably held by means of the axle element 14 and centered in the dispenser unit 3. In the in FIG. 10f As shown, the dispenser unit 3 with the adhesive film roll 13 received therein is suitable for use.

Such use can be as hand dispenser (off Figures 5 and 10f ) or as a table dispenser (see Figures 1 and 2 ) respectively. In the function as a hand dispenser, the dispenser unit 3 is held and handled by the user and is light and flexible and therefore can be used almost without restriction. In the function of a table dispenser, the dispenser unit 3 is received in the recess 8 of the base unit 2. Thanks to the increased weight of the base unit 2, the adhesive film dispenser 1 stands stable and non-slip on a table support, not shown in the figures, which allows in the optimal case a one-handed, easy operation and such removal of adhesive film strips. A stable state function of the base unit 2 can additionally or alternatively be achieved by a high static friction to the standing surface, for example by using a special coating or adhesive elements, which are mounted under the base unit 2.

The function of the adhesive film stripper 1 will be explained in more detail below with reference to the figures. The Figures 2 and 6 show the Klebefilmabroller 1 as in the function as Tischabroller in an open functional position, which is referred to as the first functional position in the context of the present application. In this a removal of adhesive film strip by a user is possible. The FIGS. 1 and 7 show the Klebefilmabroller 1 in the function of a table dispenser in a closed functional position, which is referred to as a second functional position in the context of the present application. In this user-side removal of adhesive film strip is not possible and the knife 16 is located within the recess 8 of the base unit 2 and is covered by the cantilever 15 and the partition wall 10 and the side walls 9a, 9b of the base top 6.

By comparing the Figures 2 and 6 with the FIGS. 1 and 7 it is clear that the dispenser unit 3 is rotated in the open removal position (first functional position) by about 185 ° relative to the closed position (second functional position). especially the FIGS. 6 and 7 show that the dispenser unit 3 is received for use as Tischabroller in the pivot bearing receptacle 12 at the end of the one or both arcuate grooves 11 a, 11 b.

In this case, the at least one arcuate projection 22a, 22b engages in the pivot bearing receptacle 12 and is rotatably supported therein. The diameter of the pivot bearing receptacle 12 substantially corresponds to the length of the at least one arcuate projection 22a, 22b, so that the one or two projections 22a, 22b and the pivot bearing receptacle 12 form a pivot bearing, around which the dispenser unit 3 is guided between the in the Figures 2 and 6 shown open position and in the FIGS. 1 and 7 shown closed position is pivotable.

In the in the Figures 2 and 6 shown open functional position, the dispenser unit 3 is secured in the pivot bearing receptacle 12 against unintentional release. The arcuate projection 22a, 22b is not aligned in this functional position with the arcuate groove 11a, 11b and is arranged with opposite curvature. In this way, the dispenser unit 3 can not be removed from the base unit 2, but only about the pivot bearing formed by the pivot bearing receivers 12 and the arcuate projections 22a, 22b.

Pivoting the dispenser unit 3 from the open position ( FIG. 2 . 6 ) in the closed position ( FIGS. 1 and 7 ) with reference to the FIGS. 6 and 7 clockwise. Until reaching the closed position ( FIG. 7 ), the dispenser unit 3 is pivotally fixed by the engaging in the pivot bearing receivers 12 arcuate projections 22a, 22b. Is that in FIG. 7 reaches the closed position shown, the respective arcuate projection 22a, 22b is in alignment with the corresponding arcuate groove 11a, 11b, and the direction of curvature of the respective arcuate groove 11a, 11b is identical to the respective arcuate projection 22a, 22b. Furthermore, in the fully closed position, the inner bearing element 18 of the dispenser unit 3 lies on the free end 17 of the cantilever 15 on the bearing cup 19 formed on the base unit 2. If the dispenser unit is removed from the FIG. 7 illustrated closed position with respect to the FIGS. 6 and 7 Turned counterclockwise, pivoting back to the open position (shown in FIG. 6 ) guided by the pivot bearing 12 and the arcuate projections 22a, 22b formed pivot bearing.

Taken from the in FIG. 7 illustrated closed position further pivoting of the dispenser unit 3 with respect to the FIGS. 6 and 7 in the clockwise direction, the respective arcuate projection 22a, 22b due to the alignment with the respective groove 9a, b and the same orientation of the radii R from the pivot bearing receptacle 12 solve and migrates through the arcuate groove 11a, 11b in the direction of the open end the groove 11a, 11b. In this case, the dispenser unit 3 completes a rotation about the pivot point D, which rotation takes place by means of the pivot bearing formed by the bearing cup 19 and the inner bearing element 18. After the respective protrusions 22a, 22b have emerged from the respective groove 11a, 11b, the dispenser unit 3 is completely detached from the base unit 2 and can be used as a hand dispenser in the function. This solution process is in the FIGS. 8, 9 and 3 and 4 are shown.

On the side walls 21a, 21b of the dispenser unit 3, a locking projection 25 is formed, which cooperates in the open functional position and in the closed functional position with corresponding recesses 26,27 in the respective side walls 9a, 9b of the recess 8 and in this way for a fixation the dispenser unit 3 in the respective functional position provides. In particular Figures 2 and 6 show, furthermore, the intermediate wall 10 from a stop on which the cantilever arm 15 of the dispenser unit 3 rests in the open functional position. Similarly, the bearing cup 19 forms a stop for the inner bearing element 18 when the dispenser unit 3 is in the closed functional position. In an alternative embodiment, not shown, the latching projections 25 on the base unit 2, and the recesses 26,27 may be formed on the dispenser unit 3.
