Leaf or strip dispenser

The invention relates to a material dispenser, in particular for material in strip form or in sheet form, which of a Role is unwound.

The invention is based on a dispenser for strip-shaped or sheet material which is wound on a roll and is characterized in that a take-up for the roll are provided inside the dispenser and a separating device on the outside of the dispenser container, a slot in the Container allows the material to pass from the roll to the separating device and the opposite longitudinal edges of the gap on top of each other can be pressed in order to be able to clamp the material in the gap if desired, so that the separating device is independent of it can work how much material is on the roll.

Preferably, the container consists of a box with an hinged lid, with the gap between one edge of the lid and an upper edge of a surface in the lower portion of the box is located. According to one embodiment of the invention one of the components defining the gap, preferably the upper edge of the end face of the box, carries an elastic one Part, e.g. a rubber cushion. In this embodiment, the cover is manually pressed against the rubber pad for the purpose of clamping the material

pressed and the material from the roll runs between the edge of the lid and the rubber pad. The material is on held in this way while the separator is actuated.

According to a second embodiment of the invention are instead of the rubber pad engaging teeth are provided on the two components forming the gap, i.e. on the lower edge of the lid and the corresponding top edge of the box. In this case, the cover is used to clamp the material manually pressed against the box and the material, which runs off the roll, occurs between the teeth on the edge of the Lid and that of the box. In this way, the material is held between the teeth while the Separating device is operated.

The invention is applicable, for example, in connection with food packaging consisting of plastic material film, which can be pre-perforated.

Exemplary embodiments of the invention are described below with reference to the drawing. In the drawing show:

Fig. 5 is a section of part of an inventive Dispenser in a second embodiment.

609831/0696

The film dispenser shown in FIGS. 1 to 4 has a box with a lower part 10 and a hinged lid 11, which rest on four rubber suction feet 13. The upper edge of the front surface Ik of the lower part is bent in such a way that a flange 16 is formed, from the outer end of which a sharpened separating knife 17 projects slightly upwards.

The lid of the box has a pressed portion which forms a thumb recess 19 and approximately in the middle of the Paralyzing stretch of the lid lies. Another expressed A section of the lid forms a rib to make it easier to open the box.

A rubber cushion 22 is attached to the surface of the flange 16 approximately in the middle of the longitudinal extension and when it is closed the front edge 23 of the cover 11 abuts against the rubber pad

The dispenser shown in the drawing is used as follows, a · roll 25, ζ .-. 3 * made of perforated plastic film is inserted, how it is used for packaging foodstuffs or the like. This role is discussed in section 10 below the box is inserted * The film 26 is taken from the roll through the gap between the edge 23 of the lid and the flange 16 and pulled over the sharpened cutting knife 17. To get the required length, the operator pulls the Film 26 in the direction of arrow 28. When a sufficient length of film is pulled out, the operator pulls the Film in the direction of arrow 29, whereby the film is separated.

However, when the film roll 25 is partially or fully used up, the weight of the roll in it has increased Reduced the extent that a pull on the film in the direction of arrow 29 is insufficient to sever the film. Instead it will

the roll simply lifted off the bottom of the box. In this Trap, the operator therefore uses the thumb impression to press the lid 11 firmly against the rubber pad 22 and thereby reducing the gap between the lid and the puddle to clamp the film 2β. Pulling the film in The direction of the arrow 29 then causes the cutting knife 17 separates the film as necessary.

In a second embodiment of the invention, the rubber pad 22 is omitted and lids 11 and 11 are instead Flange 16 is provided with teeth which are in engagement with one another. This exemplary embodiment is shown in FIG and this FIG. 5 shows a cross-section through part of the box in the region of the central part of the front edge of FIG Cover 11 and flange 16. Otherwise, the dispenser can be designed in the same way as in the preceding drawings shown.

The teeth 31 are integral with the top surface of the flange 16 made in the middle section and they are with the fully closed lid with similar teeth 30 in engagement, the are formed on the Yorderrand of the cover 11. Have along One-piece, 20-thread-per-inch Whitworth teeth were found suitable. The dashed lines in Figure 5 represent the lower edge of the cover 11 and the upper surface of the flange 16 on both sides of the with teeth provided middle section

In use, the film is removed from the box through the gap between the lid 11 and the flange 16. The teeth 30 and 31 are covered by the film therebetween kept open strong enough to do this. As in the embodiment described above, the film cut by the knife 17 at the desired point.

609831/0698

In this embodiment, when the weight of the roll in is reduced to such an extent that pulling the film in the direction of arrow 29 (Figure 4) does not sever the film can be, the operator uses the thumb recess 19 to press the teeth 30 tightly against the teeth 31 to thereby reducing the gap between cover 11 and flange 16 and clamping the film 26 in place. The dimensions of the teeth 30 and 31 are such that the central portion of the film is firmly gripped but not so tight that the film is severed will. The film is pulled in the direction of arrow 29 then that the cutting knife 17 sever the film as required.

Typical dimensions for dispensers of this type are as follows. The lower section 10 is approximately 30 cm to 2 m long, wherein a gap of approximately the same length is formed between the cover 11 and the flange 16. Then one can be 30 cm wider Film can be removed from the dispenser. The rubber pad 22 in the first embodiment extends only over five or eight centimeters of the total length of the 30 cm long gap. The integral teeth in the second embodiment extend only about 25 mm of this length. The dispenser is suitably made of plastic material and has a general shape Thickness of 2 mm. In any case, of course, the weight of the cover 11 alone is not sufficient to hold the film in the gap to clamp.
