Definitions
- the invention relates to a dispenser for a film, in particular an adhesive and / or correction film.
- Such dispensers have long been known, for example in the form of adhesive tape dispensers, and may in particular consist of a housing, a rotatably mounted adhesive tape roll and a severing device in the form of a knife. With the aid of the separating device, any length of the adhesive tape unwound from the adhesive tape roll can be separated off and, for example, applied to a substrate.
- DE 3109735 A1 shows a tape dispenser for the automated bonding of an adhesive tape to an object.
- a housing with an inner rotatably mounted adhesive tape roll is provided, from which an adhesive film can be applied to a substrate.
- a pusher movably connected to the housing can be moved in the direction of the substrate, which leads to a movement of a knife arranged inside the housing in the direction of the adhesive film and results in a section of the adhesive tape portion through the knife.
- the problem with this tape dispenser is the complicated structure, which consists of many different components and therefore is costly and prone to failure.
- WO 96/24549 shows a package adhesive tape dispenser with a handle to which a rotatably mounted adhesive tape roll is attached.
- an applicator roll is provided around which the unwound adhesive tape is passed, such that the adhesive tape surface provided with the adhesive can be applied to a substrate via the applicator roll.
- a projecting cutting tool is also provided here.
- it is particularly disadvantageous that a relatively large area of the adhesive side of the adhesive tape is exposed and can be soiled when not in use or storage, so that a proper resumption of work with the tape dispenser is not guaranteed.
- the object of the invention is therefore to provide an improved dispenser which overcomes the above problems. This object is solved by the features of claim 1.
- the basic idea of the invention is to provide a dispenser for a film having a housing, a film supply, a dispensing area for removing the film and a film rotatably mounted on the housing weakening device with at least one weakening means for providing the film with weakening areas as a separating aid for separating a film portion, wherein the weakening device is in contact with the film during the removal of the film from the film supply to an engagement of the at least one weakening means with the Film, wherein a removal direction for removing the film from the film supply is provided and wherein the film is designed flat and has two edges extending in the removal direction, wherein a weakening device introduced by the weakening range as a line of weakness from the first edge to the second edge extends over the surface of the film.
- the housing is made of a plastic material and substantially closed, in particular to protect the film supply and moving parts, which are preferably arranged within the housing, from external influences.
- a paper or film film can be used as the film.
- a film is conceivable, which is at least on one side surface or partially provided with an adhesive.
- the film may additionally have further features. For example, it may be made transparent, in particular not to obscure areas of text on the substrate to which the film can be applied. Also, the film may be opaque or coated to cover areas of the substrate as a correction or cover film.
- the film can be used as a marking film, for example, by being transparent or translucent, but colored, for example, to emphasize a passage of text on the substrate.
- a correction, marking or adhesive tape roll or a correction, marking or adhesive tape reel can be used as the film supply.
- further embodiments are conceivable, in particular such an arrangement of the film that this superimposed in several layers forms the film supply.
- the dispensing area for removing the film may, in particular, be designed as a gripping surface for manual removal by the user. This design is particularly suitable when using the dispenser according to the invention as a tabletop device.
- the dispenser can be used, for example, as a handheld device for applying a film, for example to a substrate.
- the dispenser region can be designed as an application device, by means of which the film can be applied to a substrate, preferably without the user himself having to apply himself to the film and possibly contaminating it.
- a great advantage of the dispenser according to the invention is the weakening device rotatably mounted on the housing with at least one weakening means for equipping the film with weakening areas as a separating aid for separating a film section.

- conventional dispensers with protruding knives or cutters may be dispensed with which a user may possibly be injured or which may lose their sharpness due to long-term use, so that separation of a film portion is no longer possible.
- Another advantage results from the use of the dispenser as a handheld device for applying a film, for example to a substrate. In this case, the film provided with one or more weakened areas is applied to the substrate via the dispensing area.
- the user can achieve separation of the applied film portion by means of the separation aid across the weakened area.

- a particularly clean separation of the film section can be made possible.
- a release aid may be provided wherein the severed film portion has a substantially straight section edge from the first edge to the second edge of the sheet film. Also, fraying or tearing of the film from the weakened area extending in a direction other than the weakening line can be avoided, so that, in particular, contamination of the dispenser by film parts can be avoided.
- Another advantage is the equipment of the dispenser with a dispensing or dispensing direction for dispensing the film from the film supply, wherein the weakened area provided in the film by means of the weakening device is substantially transverse to the dispensing direction extends to provide as a separation aid a simple separation possibility of a film section for the user.

- a deflection of the film from the film supply to the dispenser area can be made possible by the weaving device, for example, by touching the film like a segment and deflecting the course of the film during removal from the film supply.
- continuous rotation of the reel upon removal of the film from the film supply may allow continuous filming of the film with weakened areas.
- a plurality of weakening means are arranged side by side axially with respect to the roll, in particular in order to perforate the film in the weakened region or to cut it at several points.

- a film to be dispensed can represent an adhesive tape which is provided with an adhesive surface.
- the side of the adhesive tape provided with the adhesive surface can also come into contact with the roll without polluting or sticking to it, which could result in a failure of the dispenser.
- the use of a Teflon layer is also conceivable or another possibility known to the person skilled in the art for the formation of non-adhesive surfaces.

- Such a construction is preferably used in combination with an application roller at the dispensing area for applying the film to a substrate and / or with a spool as a film supply, with contact areas of these components also being aligned with the longitudinal extension of the film within the dispenser.
- Another advantage is the design of the weakening means as the above cutting or lancing means to introduce a weakening area in the form of a separating aid in the film.
- protruding knives are conceivable, which partially cut the film.
- thorns or needles are conceivable that provide the film with holes.
- a further advantage is the design of the dispenser such that the weakening device is designed as a rotatable roller and that the film in contact with the weakening device rotates the weakening device when the film is removed from the film supply.
