Description

The invention relates to a refillable dispenser for paper and / or film rolls with a housing, a roll holder, a cutter and a cover.

After EP 0 265 552 B1 a refillable dispenser for paper and / or film rolls is known in which the film is separated by transverse cutting slide. Such dispensers are used to hold paper or films in the household, in offices or workshops for the required purposes and to cut them to size.

Next was through the EP 1026 113 A3 a refillable dispenser for films is known, which consists essentially of a storage for a film supply roll with film handling, guide means for approximating a coordinated to a cutting path course of a withdrawn from the film supply roll, separating foil leading section and cutting means with at least one cutting edge in association with this path, whereby a manual movement of the film advance section, in particular its leading end, causes a relative movement of the cutting edge initiating a cutting off of the respective film advance section relative to a guide means. In this case, the cutting means, so the knife, spring loaded via a coupling with the film supply roll and triggered over the length of the peeled film piece or via separate buttons. A particular disadvantage is the need to rotatably support the film roll on a special shaft. The film roll must be frictionally connected to the shaft. This is especially difficult with the frequently encountered, coreless film rolls. In addition, safe handling is possible only by further measures such as two-hand release.

The GB 1 256 441 A describes a dispenser for strip material having a pivotable counter bearing for a knife. If the counter bearing is guided against the strip material, the strip material comes into contact with the knife and can be cut off.

The US 2,992,582 A describes a dispenser for adhesive tape having a pivotable knife. The knife carrier can be removed from the dispenser.

The US 3,762,261 A describes a device for separating strip material which is rolled up on a roll. The device comprises two ring halves, which can be rotated against each other. The one half of the ring has a knife and the other half of the ring has an abutment.

The object of the invention is to provide a refillable dispenser for film and / or paper rolls, in which the cutting process is automated and accidental crushing into the knife during the cutting process is excluded.

This object is achieved in that the cutting device consists of a coaxial with the roll holder, movable knife carrier with a roll width superior knife, the knife carrier is equipped with a handle for radial Schnittverschwenkung and covered in the process of Schnittverschwenkung by the cover. The knife can be installed both parallel and at an acute angle to the roll axis and it can cut along a counter knife arranged on the housing. The additional spherical design of the knife leads to an even safer cutting result. These measures lead to a pulling cut, which of course also very sensitive plastic films can be cut.

To simplify the structure, the roll holder is designed as a simple tray.

In order to carry out the cutting operation unimpeded by different manual forces, the knife carrier is coupled to a clamping device. The clamping device can consist of a separate clamping lever and be coupled to the movable cover. It is triggered after the cover covers the way of the knife, so that a risk of injury is excluded. Since the knife performs its cutting motion evenly by the force of a spring, a secure cut is guaranteed. When cutting and severing the film, the knife engages in an abutment in the form of a labyrinth so that a secure cut takes place, the more so if this abutment is designed as a counter knife. The function is further improved by clamping the film between the anvil and the cover during the cutting process.

An embodiment of the invention will be explained in more detail below with reference to the drawings. Show it:

1 A front view of a refillable dispenser,

2 a section along the line II-II in 1 , and

3 a section along the line III-III in 1 ,

In a housing 1 with side walls 2 is a roll holder 3 to take a role 4 arranged. For separating individual pieces from the roll 4 is a cutting device 5 intended. The roll holder 3 with role 4 and cutting device 5 can through a panel 6 (Cover 21 ) are concealed.

In addition, to act on the cutting device 5 a thumbwheel 7 in one of the two side walls 2 stored.

The roll holder 3 is over stub axle 8th in the side walls 2 Swung out of the housing. The positioning in the housing 1 takes place via a stop 9 , She has a hollow 10 to take up the role 11 and is on the front with a recessed grip 12 Mistake. Below the recessed grip 12 is a counter bearing 13 with a dip slot 14 intended. To swing out the roll holder 3 to change or insert a new role 11 are handles on both sides 15 formed.

The cutting device 5 consists of a cross-sectionally curved knife holder 16 with at least the width of the roll 4 running knife 17 , the adjusting wheel connected to the knife holder 7 , as well as with a by a spring, which is not shown acted upon control unit 18 , About the wheel 7 and the control unit 18 is the cutting device 5 rotatable in the side wall 2 stored. The essential components of the control unit 18 are a latching tongue 19 and a driver stop 20 whose function will be explained later.

The aperture 6 , Part of a cover 21 , comes with a handle bar 22 adjusted and is by a stop 23 providing the maximum opening angle. The cover 21 has side walls 24 about which they are also in the side walls 2 is rotatably mounted. The central axis is with 25 characterized.

The function of the refillable dispenser is explained in more detail below.

The 1 to 3 show the condition with open aperture 6 or cover 21 , tensioned cutting device 5 and the roll ready to peel off a film or paper piece. To a piece of paper or foil 26 to cut it off, you pull this in the direction 27 over the counter bearing 13 , To trigger the cutting process, the aperture is 6 by means of the handle bar 22 in the direction of the arrow 28 in front of the counter bearing 13 panned until it stops 23 abuts this pivotal movement in the direction of the arrow 28 causes the wheel via the 7 This can be directly with the cover 21 be connected or be taken by them, the catch tongue 19 the cutting device 5 through a cam 29 on the wheel 7 against the axis 25 is pressed and away from the latching bracket 30 solves. As a result, the cutter pivots 5 with the knife 17 radially downward (Schnittverschwenkung 31 ) and the knife 17 dives into the immersion slot 14 and separates the over the counter bearing 13 by means of the aperture 6 stretched film.

After the cut, the renewed tension of the cutting device takes place in that this on the setting wheel 7 or the cover 21 against the cutting pivot 31 over the cam 29 at the driver stop 20 is pushed back until the cam 29 behind the latch 30 snaps
