Abstract

A film dispenser comprises a housing provided with at least one dispensing compartment, and a separating profile section associated with a dispensing opening of the dispensing compartment. A separating device comprising at least one separating knife and a press element is supported such that it is movable along the separating profile section transversely to a slip of film which is drawn from a roll of film disposed in the dispensing compartment. A separating device can also be implemented as a separate component and used together with a dispensing compartment and a suitable separating profile section independently of the film dispenser as an attachment or as an insert component for the film dispenser. In order to improve a film dispenser or a separating device of this kind in such a way that the drawn slip of film can, for the purpose of cutting, be fixed more effectively on the basis of a simple structural design and at a reasonable price, the press element is implemented as a moving strip which is supported such that it is adapted to circulate in said separating device and which causes the slip of film adjacent to the separating knife to remain tensed at least in a linear manner along the direction of displacement of said knife.

Description

The invention relates to a separating device and a film dispenser with such a separating device having the features of the preambles of patent claim 1 and 21, respectively.

From the WO 95 046 94 a corresponding separating device is known, which forms part of a film dispenser. In this separator endless soft rubber bands are provided as hold-down means, which run around as rims trained roles. The rollers are arranged on both sides of a corresponding cutting knife in pairs.

A film dispenser with a separator is for example from the DE 93 21 258 U known. In the prior art film dispenser two dispensers are arranged one above the other, in each of which a film roll is contained. Along the dispenser each separating device is slidably mounted. This has at least one separating knife and a pressing element. The pressing element is formed by one or a pair of rollers, which press a withdrawn from the film roll foil lug in the direction of the separating knife before and behind this to a release profile. The separating profile has a cutting slot into which the separating knife partially engages. The role as a pressure element after DE 93 21 258 U fixes the foil lug in the region of the cutting slot substantially only punctiform. Furthermore, at least two pressure rollers are in use to a sufficient fixation of the film web, whereby the separating device for the arrangement and storage of the pressure rollers is structurally relatively expensive.

The invention is therefore based on the object to improve a separator or a film dispenser of the type mentioned in that in a structurally simple and inexpensive way, the film flag is better fixed for cutting.

This object is solved by the features of patent claims 1 and 21, respectively. According to the invention, the foil lug is not only punctiform fixed, but linear in the direction of the separating knife. As a result, the foil lug is held during the cutting over a longer portion in the direction of displacement of the separating knife, whereby the film is easier and better cut. The article according to the invention gives a clean cut edge without fraying and tearing along the cutting line. The treadmill is mounted in a simple manner circumferentially movable in the separator and there are no separately stored and trained in a special way pressure rollers required.

With regard to the separating device is still to be noted that it can be used as an integrated part of a film dispenser, or as a separate component regardless of a film dispenser. The separator can be used to cut different sheet or sheet materials, such as film or paper. When using the corresponding separating device in a film dispenser, the corresponding material is in particular formed as a foil lug and may be formed from paper, aluminum or a plastic material.

In this context, it should also be noted that, depending on the width of the treadmills, a surface-like pressing of the foil lug adjacent to the severing knife also takes place accordingly.

In order to fix both the film web and the separated foil lug, at least one treadmill can be arranged on both sides of the severing knife.

In order to move the treadmill easier to circulate, it can be rotatably mounted. The corresponding storage can be done via rollers or the like.

In order to use over the entire length of the separation profile associated portion of the treadmill for fixing of foil lug can
the treadmill be guided in the direction of the separating knife substantially parallel to the separation profile.

In order to guide the treadmill also in front of and behind the separating device, a parallel guidance of the separating device for the treadmill can extend on both sides in the direction of displacement beyond the separating knife. As a result, a fixation of the film is carried out by the treadmill before the cutting knife, maintained next to the cutting knife and continued until behind the cutting knife.

In order to be able to handle the separating device with the separating knife easily, the separating device can have a two-part handle housing, in particular, in which the separating knife is held and the treadmill is guided.

In order to easily construct the separating device in a further exemplary embodiment, the separating device can be formed from a substantially U-shaped handle housing, which can in particular be releasably latched onto an inner body. The inner body serves in this context as a carrier for the separating knife. Around the inner body, the treadmills are guided around and in particular relative to this movable. The separating knife may protrude between the treadmills on an underside of the inner body.

In order to fix the separating knife in the handle housing in a simple manner and to fix it in its position, at least one handle housing half can have a fastening element for the separating knife and a handle housing half a stop element for the separating knife. The stop element may be formed as a shoulder in the handle housing half, on which the cutting knife rests with an upper edge and is thus prevented from tilting about the fastener.

In a simple embodiment, fastening and / or stop element may be pin-shaped or pin-shaped. The separating knife has corresponding openings for passing through the pin or pin-shaped elements. For example, instead of the heel-shaped stop element and a pair of stop pins be provided, which are at spaced locations with an upper edge of the cutting blade in abutment.

To store the treadmill in a simple manner movable in the handle housing, the handle housing half may have a slot guide for the treadmill. As a result, no rollers or other rotatable elements for supporting the treadmill are necessary.

For example, if two treadmills used on both sides for cutting knife, a treadmill can be performed in each handle housing half.

The handle housing halves may be constructed substantially symmetrical to each other, wherein the separating blade can be held between the handle housing halves. The handle housing halves can be connected to one another, for example, by means of a screw or other connecting elements. When connecting the handle housing halves the cutting blade is fixed tilt-proof by mounting and contact element in the handle housing.

In order to arrange the cutting blade in a simple manner in the separating device, the cutting blade can be integrally formed with the inner body. As a result, the unit inner body separating knife is vorfertigbar and can be connected to the substantially U-shaped handle housing by its snapping. In this context, it should also be noted that regardless of the type of separating knife, the inner body may be formed uniformly in order to lock also integrally formed handle housing can be on him. As a result, the handle housing can be exchanged in a simple manner.

In order not to cause excessive frictional forces between the treadmill and handle housing half in one embodiment of the invention, the treadmill may be guided around a roughly kidney-shaped guide body in the handle housing half with play. As a result, the treadmill is not too close to the guide body, whereby the friction between the two could hinder movement of the treadmill around the guide body.

In order to be able to cut an aluminum foil well and safely, the separating knife can be made of plastic.

In a separating knife made of plastic, it may be considered advantageous if this is made in one piece with the inner body also formed of plastic.

In order to be able to cut a plastic film accordingly, the separating knife may be made of metal.

If the separating knife is made of metal, it can be assembled with an inner body made of plastic by gluing or other joining into a one-piece unit. It is also possible to spray the inner body directly onto the cutting knife.

In order to simplify a guidance of the separating device along the cutting slot, the separating knife can have a base body guided in a corresponding guide along a cutting slot of the separating profile. The base body is arranged on an end of the separating knife opposite the handle housing and can be displaced along the guide. The base body may be supported in different ways within the guide to prevent release of the separator from the separation profile. Various types of base body and guide are, for example, in the above-mentioned utility model DE 93 21 258 U described. Corresponding guides and base bodies are also usable in the present invention.

In order to store the separating device in a simple manner and without additional constructive measures, the separating profile can be formed in a dispensing compartment associated, pivotable between an open and a closed position flap. The flap is used to open the dispensing compartment and to insert a new roll of film or for initial removal of the film flag, which is guided through a slot between the flap and the housing or between adjacent flaps to the outside. The separating device can also be designed as a separate component with optionally integrated dispensing compartment. The component can also be used separately without a foil dispenser.

So that each flap securely retains the film roll in the housing, the flap can be detachably latched in the closed position with the housing.

In order to store the flap in a simple manner pivotally and possibly also perform the locking in a simple manner, the flap can be pivotally mounted at its lateral ends in the housing and / or be latched.

In order to be able to guide the flap securely into its closed position and at the same time to limit the dispensing pocket laterally in the open position, the flap can have side walls protruding at its lateral ends in the direction of the corresponding dispensing compartment. These engage in pivoting the flap in the closed position in the dispensing compartment and serve at least partially as a guide along the Verschwenkweges the flap. In addition, the side cheeks form at flap in the open position lateral boundaries that simplify insertion of a film roll or prevent accidental falling out of a film roll.

In order to pivot the flap as far as possible in the housing, can project at the lateral ends of the flap bearing axles. To this bearing axes, the flap between the closed and open position is pivotable. The bearing axes can be arranged so that the flap is arranged in the closed position substantially flush with a front side of the housing.

In order to perform the latching in the closed position in the region of the lateral ends of the flap, and corresponding latching elements can be arranged at these lateral ends. In one embodiment, each side cheek having an elastically deflectable arm on which a latching element is arranged, which is in the closed position with a counter-locking element on the housing in engagement.

For example, may be formed on the arm, a detent recess which engages in engagement with a corresponding latching projection in the interior of the housing in the closed position of the flap. In another embodiment, the locking element as a locking lug and the counter-locking element than in the interior of the housing above Locking projection be formed, which is engaged behind in the closed position of the flap of the locking lug.

The side walls of the flap are assigned in the housing corresponding side housing end walls. In this open recesses may be formed in the direction of the flap, of which in the closed position of the flap arranged on the side cheeks bearing body are added. As a result, for example, the closed position of the flap can be fixed.

The abutment bodies can be formed directly on the lateral ends of the flap or on the side cheeks. In order to use the body simultaneously as actuators for elastic deflection of the arms, the plant body can be arranged in particular at free ends of the arms. By pressing on the contact body in the direction of the flap, the arms are deflectable, so that the engagement of locking element and counter-locking element is releasable. It should be noted at this point that the flap can also be formed with only one side cheek, corresponding latching in the region of this side cheek and only one contact body. For improved handling and fixation of the flap in the closed position, however, two side cheeks with corresponding locking elements and abutment bodies are generally preferred.

Investment elements of sufficient size and ergonomically advantageous shape arise when, for example, the recesses semicircular and the plant body is circular segment-shaped. As a result, the abutment bodies can be pressed by fingertips of a user from outside to inside in a simple manner.

In order to realize the latching projection in the region of the recess and close to the recess, an edge of the recess may be at least partially formed as a latching projection.

In order to improve the appearance of the film dispenser flap in the closed position, the flap above the contact body may have an edge projection which is arranged flush in the closed position of the flap to the front of the housing in the recess. The abutment bodies extend close to the edge projections, not only flush with the front, but also can be arranged flush with side surfaces of the housing.

In order to be able to easily form the arm in the side cheeks, the arm in the side walls of the flap can be delimited by two slot recesses open in the direction of the edge projection. As a result, the side wall with arm and corresponding other components can be produced in one piece.

In order to store the flaps in a simple manner and at the same time be able to detach them from the housing, may be laterally formed next to the recess on the housing in the direction of recess axis guide for receiving the laterally projecting from the flap bearing axis. The axle guide serves on the one hand for pivotable mounting of the bearing axis and on the other hand via its opening in the direction of recording, the bearing axles can be led out of the axle guide and correspondingly the flap can be detached from the housing.

There is the possibility that the base body is guided directly along an inner side of the flap where it is at least partially in contact. In order to prevent the base body and thus the guide of the separating device from damage or obstruction by the dispensing compartment disposed in the film roll, may be formed on a housing facing the inside of the flap along the cutting slot extending guide channel, in which the base body received and / or is guided.

For material-saving production of the guide channel, this may have in its side walls in the longitudinal direction spaced from each other arranged longitudinal openings.

In order to mount the separating device in such a guide channel in a simple manner, a longitudinal opening may be formed as an insertion opening for the separating knife. After inserting the cutting blade in the insertion opening and after pushing the cutting blade through the cutting slot, it can be mounted on an outside of the flap on the corresponding handle housing.

For improved guidance of the base body, the side walls of the guide channel with the inside of the flap can include an acute angle, whereby the side walls converge toward each other from the inside and thereby the guide channel receives a trapezoidal cross-section.

The base body may be formed in different ways, see the already mentioned DE 93 21 258 U , For example, the base body may be directly in contact with edges of the cutting slot and guided along these edges. There is also the possibility that along the cutting slot at least one guide for the base body is arranged on the inside of the flap. The base body may then be shaped accordingly to be guided along this guide.

In order to solve the separator even without disassembly of the handle housing of the flap, the flap may have a pivoting flap which forms an edge of the cutting slot in its flap closing position. If this pivoting flap is opened, the separating device can be removed.

In order to simplify the mounting of the pivoting flap on the flap, the pivoting flap can be pivotably mounted on the flap via a film hinge.

In order to secure the pivoting flap in its closed position, it may have on its underside at least one latching cam, which engages in the flap closing position in a longitudinal opening of the guide channel. The locking cam can be solved manually, for example, with the door open from its locking engagement.

In order to simplify the release of the locking cam, the locking cam may be formed on an elastically deflectable latching arm.

In order to be able to use also from a front side of the flap in a simple manner separating profile and separating device, the flap may have a running in its longitudinal direction of the guide channel, in which a cutting slot of the separating profile having bar is arranged in particular removable. The strip can be used at the same time the separator.

As a rule, the strip with the separating device is installed in the film dispenser in order to cut off a film strip which has been correspondingly pulled out of the film dispenser. However, if the strip is removable, it can also be used separately from the foil dispenser for cutting. For this purpose, the bar, for example, on a flat surface, such as a table or the like, can be placed. By means of the run along the bar separator then a corresponding film is also independent of the film dispenser cut off.

Arranging the strip can be done, for example, from one end of the guide channel, which can then be open at least one end.

In order to obtain a smooth front of the flap when using the bar, the bar can be arranged with its upper side substantially flush with the front of the flap in the guide channel, the separating slot extends in the top.

In connection with the separately usable strip, however, it may prove to be advantageous if it has a substantially square cross-section, projecting from its upper side support flanges. When arranged in the front of the flap bar and these abutment flanges can be arranged flush with the front of the flap, if appropriate for the support flanges depressions are formed in the front. However, if the bar is used separately from the film dispenser, the seat flanges can be used to better lay down a film and then cut that film.

In order to use the bar at the same time to guide the separator, the bar can be substantially hollow and in it the base body of the cutting blade can be performed.

There is also the possibility that is dispensed with open ends of the guide channel, for example, by inserting the bar in the guide channel and then latched. Alternatively, the bar can be mounted in another way in the guide channel, such as by screwing, gluing or the like.

Advantageously, the strip may be formed of a plastic profile, which is one piece.

In order to reliably prevent displacement of the separating device when the film is displaced along the separating slot, a friction-increasing coating can be applied at least on one side along the separating slot.

In order to ensure that the treadmills circulate during movement of the separating device along the dividing slot, the treadmill can be formed from or on its outer side in contact with the foil web, a material with increased friction.

In order to better hold the films ready for a user of the film dispenser and at the same time be able to carry out a cutting of the film flag more easily, the housing can have an obliquely upward and forwardly extending rear wall. As a result, with otherwise vertically extending front of the housing, the dispensers and flaps are arranged with hung on a wall of film dispenser so that they are opposite to the user.

In order to be able to store and provide a roll of paper on the film dispenser according to the invention in addition to, for example, a plastic film roll and an aluminum foil roll, a holder for a paper roll can in particular be arranged pivotably on a lower side of the housing.

In the following advantageous embodiments of the invention will be explained in more detail with reference to the accompanying figures in the drawing.

In FIG. 5 the flap 28 is shown with pivoting flap 60 in the open position 76. The pivoting flap 60 is connected to the flap 28 via a film hinge 63. An edge 62 of the pivoting flap 60 forms an edge of the cutting slot 24, see also FIG. 2 ,

In FIGS. 6 and 7 are corresponding views from the side on the ends 30 of the flaps 28 after FIGS. 4 and 5 shown. In FIG. 6 is the pivoting flap 60 in the closed position and in FIG. 7 arranged in the open position 76.

The lateral end 30 is formed by the side wall 31. This has an elastically deflectable arm 35 which extends obliquely upwards and is bounded on both sides by slot recesses 47, 48 open in the direction of the edge projection 45. At the free end 43 of the arm 35 of the contact body 42 is arranged. This is approximately circular segment-shaped, wherein the circular circumference line points in the direction of the arm 35. On the arm 35, a locking lug 36 is arranged below the contact body 42 as a latching element. This engages behind the flap 28 in the closed position 27 designed as a counter-latching element 37 and latching projection edge 44 of the recesses 40, 41st

When pivoting flap 60 in the open position 76 is on the bottom 64 a guide visible. This is formed by two guide webs 79, 80 and a guide groove 81 arranged between them. Guide bar 79 is formed with a lower height than the guide bar 80. Along the guide webs and also along the guide groove 81 is a base body 25 of the separator 7, see in particular FIGS. 11 and 12 , feasible.

The side walls 53 of the guide channel 51, 52, see also FIGS. 4 and 5 , enclose an angle 57 with the inside 50 of the flap 28. At the flap after FIG. 3 For example, the angle 57 may be pointed so that the respective side walls 53 taper toward each other from the inside 50.

In FIG. 8 is the pivoting flap 60 fully open and guide 23 is visible along which the separating device 7 is guided. Furthermore, the guide webs 79, 80 and the guide groove 81 arranged between them are again visible, which serve for the displaceable mounting of a corresponding base body 25 of the separating device 7.

In FIG. 9 is a view of a side wall 31 at the lateral end 30 of the flap 28 after FIG. 3 shown. The structure of the side cheek with arm 35, abutment body 42 and locking lug 36 and slot recesses 47, 48 is substantially analogous to the side wall of the FIGS. 6 and 7 , A difference to the side wall previously shown is that no pivoting flap 60 is part of the flap 28, but, see also FIG. 3 , the cutting slot 24 is disposed directly in the front 46 of the flap 28. Furthermore, an acute angle 57 is formed between the side walls 53 of the guide channel 51, 52 and an inner side 50 of the flap 28.

In FIG. 10 is a perspective view obliquely from above of a further embodiment of a flap 28 is shown. In this embodiment, a guide channel 67 is formed in the flap 28, in which a bar 68 is used. The strip 68 can be inserted from the front side 46 of the flap 28 into the guide channel 67 and fixed there by means of an edge lock 84. The strip 68 is made of a plastic profile and has in its upper side 70 the cutting slot 24 of the separating profile 6. For locking the Leite 68 in the guide channel 67, the bar in the direction of cutting slot 24 is compressible and due to the inherent elasticity of the bar 68 locks it after insertion into the guide channel 67 with the edge lock 84. Guide channel 67 and bar 68 are formed so that the top 70th the bar 68 is arranged flush with the guide channel inserted bar to the front 46 of the flap 28.

In an embodiment of the strip 68, not shown, this is independent of the film dispenser 1 used. For this purpose, the strip is removed from the guide channel 67 and placed on a substantially flat surface, such as a table or the like. On its upper side 70, which optionally has laterally projecting bearing flanges, a foil lug is placed and by means of the separating device 7 separated. In this way, the strip 68 can be used independently of the film dispenser for cutting corresponding films. Depending on the type of film, the separating device may be formed with a corresponding separating knife.

The strip 68 is hollow on the inside and thus serves directly as a guide 23 or guide channel 51, 52 for a base body 25 of a separating device 7, from the in FIG. 10 essentially only a separating knife 8 is shown arranged at the lower end of the base body 25.

The base body 25 has a cross section corresponding to the cross section of the bar 68. The separating knife 8 is fixed to the base body 25 and has on both sides and above the base body 25 cutting edges 78 which are displaced along the direction of displacement 13 through the cutting slot 24. Centered between the cutting edges 68 and adjacent to a abutment edge 82 of the cutting blade 8 a Einhängebohrung 77 is arranged.

In FIG. 11 a further embodiment of a separating device 7 is shown, which is used in the film dispenser according to the invention. The separating device 7 has a two-part handle housing 15 made of handle housing halves 16 and 17, see also FIG. 12 , on. The handle housing half 16 after FIG. 11 has a pin-shaped fastening element 18 on an inner side facing the separating knife 8 and above this and spaced apart from each other two contact elements 19. The separating knife 8 can be suspended with its suspension hole 77 on the fastening element 18 and the abutment edge 82 abuts the abutment elements 19 from below. Instead of two spaced contact elements 19 can also be a paragraph-shaped, single contact element 19 may be formed in the handle housing half 16.

The handle housing half 16 or also 17 has an approximately kidney-shaped guide body 21, around which a treadmill 11 is guided as a pressure element 9. Another treadmill 12 is movably mounted in the other handle housing half 17 accordingly. In the upper region of the guide body 21 this is surrounded by a slot guide 20 in which the treadmill 11 and 12 is inserted. The treadmill is wrapped around the guide body 21 with play and in particular by a bottom of the guide body 21 as a parallel guide 14 adjacent to the cutting slot 24 pressed.

The separating knife 8 after FIG. 11 is made of metal and is used for cutting plastic film, it being analogous to the embodiment of FIG. 16 has two lateral cutting 78. At the lower end of the separating knife 8 is fixed to the base body 25. This is stepped, with a step surface at the free end of the guide web 79 rests and engages a step rear wall 86 in the guide groove 81, see in particular FIG. 7 ,

In FIG. 12 is the separator 7 after FIG. 11 assembled, wherein the further handle housing half 17 with the in FIG. 11 shown handle housing half 16 is connected for example by screwing. On outer sides of the handle housing halves 16, 17, a recessed grip 83 is formed for easier handling of the separating device 7.

In both handle housing halves 16, 17 is respectively, see FIG. 11 , a treadmill 11, 12 movably guided.

In FIGS. 13 and 14 is shown as another embodiment of a separator 7 another cutting knife 22. This is made of plastic material and is used for cutting aluminum foil. Analogous to the previous separating knives, it has two lateral cutting edges 78. In this case, the separating knife 22 is integrally molded with base body 25 made of plastic material. The base body 25 has guide shoes at its free ends, which for guidance along the guide channel 51, 52, see for example FIG. 9 , serve.

In FIG. 14 is a section taken along the line XIV-XIV FIG. 13 represented by the separating knife 22. In particular, the trapezoidal shape of the lateral guide shoes 87, which match the cross section of the guide channel 52, see FIG. 9 , are formed.

In FIG. 15 is a bottom view of the separator 7 according to the preceding figures without corresponding separating knife 8, 22 shown. The two handle housing halves 16, 17 are, see also FIG. 12 , bolted together and are constructed substantially symmetrical to each other. In each handle housing half 16, 17, a treadmill 11, 12 is movably mounted. On their outer sides, the handle housing halves 16, 17 on the recessed grips 83.

The treadmills 11, 12 may be coated with a friction-increasing material on their outer side 71 facing the corresponding flap 28 or may also be formed entirely of this material. A corresponding friction-increasing material 87, see FIG. 10 may also be applied along the cutting slot 24 on the top 70 of the ledge 68.

In a further embodiment of the invention, the separating device 7 is composed of a smaller number of individual parts. In this case, the handle housing 16, 17 is integrally formed and substantially U-shaped. Within the handle housing, an inner body can be used in particular by latching. Around the inner body around the treadmills 11, 12 are movably guided, see also FIG. 15 , Centered between the Laufbändem 11, 12 is from the lower side of the inner body, the cutting knife 22 before. Due to the snap-fastening of handle housing and inner body, the handle housing is easily replaceable and inner body and handle housing are constructed so that inner body with different separating blades, each with a similarly constructed handle housing can be connected.

The inner body is preferably formed from plastic. If the separating knife is also made of plastic for cutting aluminum foil, separating knife and inner body are produced in one piece in a manufacturing process.

If the separating knife is made of metal for cutting plastic film, the separating knife is in particular detachably connected to the inner body, or the inner body is sprayed onto the metal separating knife.

The locking between the handle housing and inner body can be done by appropriate locking elements and counter-locking elements on the two items. Of course, another type of releasable attachment between separating knife and handle housing is possible, such as screwing, gluing etc.
