Description

The present invention relates to a dispenser box for wipes and in particular for wet cleaning wipes made of nonwoven according to the preamble of claim 1. Furthermore, the present invention relates to a refill pack and a device for producing a cloth wrap for such a dispenser box.

Dispenser cans of the generic type are known in many embodiments and are on the market. They preferably hold wet wipes made of nonwoven for use as cleaning wipes, facial tissues, baby wipes or the like. So that the cloth wrap in the can cannot get dirty and drying out of the wet wipes is avoided, a slot is provided as a removal opening, for example in the form of a so-called tear-off star, through which the cloth web is pulled. As soon as a web section formed by corresponding perforations has been pulled completely out of the removal opening, the cloth can be separated from the web as a single section.

When dealing with the dispenser box, the problem arises that when opening a new dispenser box or inserting a refill into an existing dispenser box, the first sheet section has to be plucked out of the cloth wrap and laboriously threaded through the removal opening, which is difficult due to the slot shape of the removal opening . In order to make it easier for the end user to handle the dispenser box, the first sheet section was plucked manually by the manufacturer - for example with the help of tweezers - from the inside of the cloth wrap, so that the beginning of the cloth web could be identified. However, this is cumbersome and time and personnel consuming.

To solve the threading problem, it has already been proposed to attach a threading aid in the form of a pin to the dispenser box or corresponding refill packs, which has a larger eyelet that fits through the slot for pulling in the first sheet section and then pushing the threading aid through the removal opening together with the first Has leaf section. Experience has shown, however, that consumers have problems when using these threading aids, because they do not recognize their purpose. In this respect, it was previously necessary to attach appropriate operating instructions to the can or the refill. However, this measure did not lead to the desired success, since many consumers still did not use the threading aid. On the other hand, threading is unnecessarily cumbersome, since the first web section first has to be pulled through the eyelet of the threading aid.

Proceeding from this, the object of the invention is to improve a dispenser box of the generic type or a refill pack for it in such a way that a corresponding threading aid can be used in a very simple manner and thus "foolproof".

This object is achieved by the measures specified in the characterizing part of claim 1 or 8. Accordingly, a threading mandrel for pulling the web through the removal opening is attached to the first sheet section of the web. In connection with the claimed refill according to claim 8, such a threading mandrel is also fastened to each refill pack on the first sheet section of the cloth wrap, the cloth wrap being wrapped in a packaging with the threading mandrel. The threading mandrel can be attached to the blade section in any conceivable manner, for example by gluing, welding, riveting or the like.

Since gluing or welding is difficult, particularly in the case of damp cleaning wipes, according to the embodiment of the invention specified in claim 2, a claw fastening of the threading mandrel is the first Track section provided. This enables a sufficiently stable connection between the threading mandrel and the web section to be created, particularly in the case of nonwoven cloths. After threading the web section, the threading mandrel can then be torn off and thrown away or the cloth can be used with it.

Claims 3 to 7 and 9 characterize further preferred embodiments of the subject matter of the invention, the advantages of which become clear from the following description of the figures.

Claims 10 to 18 relate to a device for producing a cloth wrap for a dispenser box or for a refill, as well as advantageous developments of this device.

1 and 2, a dispenser box 1 for wet wipes made of nonwoven fabric is shown, which consists of a container 2 and a lid 3 sealing this moisture-proof. For this purpose, the lid 3 can be snapped or screwed onto the container 2.

A recess 4 is provided centrally in the lid 3, in the bottom 5 of which a slot 6 is let in as a removal opening. If a plurality of such slits are arranged crossing one another in the base 5, the removal opening is designed as a so-called tear-off star.

In the container 2 there is a cloth wrap 7, which is formed from a web 8 of nonwoven which is wound on itself without a winding core. The web 8 is divided by transverse perforations 9 which are equidistant from one another into individual, separable sheet sections 10 which form the individual sheets.

A threading mandrel 11 is fastened to the first sheet section 10 'of the web 8 in such a way that it is arranged in the region of the edge 12 running parallel to the longitudinal direction L of the web and projects with its introducer 13 at right angles thereto. The cloth roll 7 is wound so that the first sheet section 10 'comes to rest in the center of the cloth roll 7, with which the threading mandrel 11 is arranged in the center of the cloth roll 7 and protrudes upward from the roll 7 concentrically with the winding axis 14 (FIG. 1) . With such a configuration of the cloth roll 7 and the threading mandrel 11, the dispenser box 1 reaches retailers and consumers.

When the dispenser box 1 is opened, the cover 3 is removed, whereupon the threading mandrel 11 stretches out to the user in a conspicuous manner. It only needs to be gripped and pulled out, with which the web 8 is pulled out of the cloth roll 7 via the sheet section 10 '. The threading mandrel 11 is then inserted through the slot 6, whereby the web 8 is simultaneously threaded through this slot. This state is shown in Fig. 2. For further use, the lid 3 is placed on the container 2. The web 8 can then be successively pulled through the slit 6 and sheet section 10 separated by sheet section 10.

In Fig. 3, a refill 15 for the dispenser 1 is shown. In this pack 15 a cloth roll 7 'is stored, the first sheet section of which is in turn provided with a threading mandrel 11 which is arranged in the center of the cloth roll 7' and protrudes from its winding axis 14.

The cloth roll 7 'of the refill 15 is sealed in a soft film packaging 16 which has a bulge 17 for receiving the threading mandrel 11.

7, 8 and 10, the special configuration of the threading mandrels 11 and the connection technology with the blade section 10 'can be explained. Each threading mandrel 11 is provided with laterally protruding claws 19 in a shank region 18 which takes up approximately half its length. These penetrate the web section 10 '. Their ends 20 are flattened in the manner of a rivet connection, so that the blade section 10 'is enclosed between the flattened ends 20 and the shank region 18 of the mandrel (see FIG. 10, part III).

As is clear from FIG. 8, each threading mandrel 11 has a tapered grip 22 in front of its introducer 13.

A device according to the invention for the production of a cloth roll 7, 7 'for the dispenser box 1 or the refill pack 15 can be explained with reference to FIGS. 4 to 6 and 9 and 10. The device arranged in a conventional machine frame 23 has a feed device 27 provided with a plurality of deflection and drive rollers 24, 25, 26, with which a nonwoven web 8 is fed from a supply roll (not shown). This is followed by a perforation device with a perforation roller 29 and a corresponding counter and deflection roller 30. While the web 8 passes through the perforation device 28, the transverse perforations 9 are introduced into the web 8 at regular intervals.

The web 8 is fed to the connecting device designated as a whole by 34 via further deflection rollers 31, 32, 33, which also ensure a uniform web tension. In this, a threading mandrel 11 is fastened to the first web section 10 ′ of each cloth roll 7. The exact design and mode of operation of the connecting device 34 will be dealt with in more detail below.

After further attachment of the threading mandrel 11, the web 8 is fed via further deflection rollers 35, 36, 37 to the winding device 38, in which it is wound on itself with a corresponding number of sheet sections 10 without a winding core. The web 8 is separated in accordance with the desired winding length and the finished wound cloth winding 7 is ejected automatically in the usual way.

Furthermore, it should be pointed out that the device shown in FIG. 4 guides several webs 8 in the longitudinal direction L directly next to one another, to which the individual components of the device are matched accordingly. Analogously, the connecting device 34 shown in more detail in FIGS. 5 and 6 is present several times in a number corresponding to the number of the individual webs. Each of these connecting devices 34 has a bearing drum 39, on the circumferential surface 40 of which a threading mandrel 11 can be fixed. The width B of the bearing drum 39 corresponds essentially to the length of the shaft region 18 of the threading mandrels 11. The bearing drums 39 are flanked by deflection rollers 41, which are arranged concentrically with these and have the same diameter as the bearing drum 39. To fix the threading mandrel 11 on the peripheral surface 40 of the bearing drum 39, a slot 42 is provided in the latter, which is connected to a vacuum source. The threading mandrel 11 is thus sucked in via the slot and held there.

The threading mandrels 11 are fed to the bearing drum 39 via a feed device 43. The threading mandrels 11 are not fed therein individually but in the form of a so-called belt 44. In this belt 44, the individual threading mandrels 11 are connected side by side via thin film connections 45. The belt 44 is pulled off the supply roller 46 via a deflection roller 47 and pushed along a guide rail 48 to the bearing drum 39. An additional hold-down rail 49 is provided on the drum-side end of the guide rail 48 for clean guidance of the belt 44.

As is clear from FIG. 5 in phase I, the leading threading mandrel 11 ′ of the belt 44 runs onto the bearing drum 39 and is held there by the vacuum application of the slot 42. The leading threading mandrel 11 is then separated from the belt 44 by a cutting device 50, which is designed in the manner of a drop knife is. As soon as the threading mandrel 11 fixed on the slot 42 is to be connected to the web 8 running over the bearing drum 39 and the deflecting rollers 41 flanking it in the region of a first sheet section 10 'via a corresponding machine control, the bearing drum 39 is set into a corresponding rotary movement, as a result of which its peripheral surface 40 runs synchronously with the web 8. As soon as the threading mandrel 11, whose claws 19 point radially outwards, comes into contact with the web 8, the claws 19 penetrate it. The penetration is supported by the brush roller 51 assigned to the bearing drum 39, so that the web 8 is pushed completely onto the claws 19 (see phase II, according to FIGS. 5 and 10).

Furthermore, the connecting device 34 is assigned an anvil roller 52, which fixes the threading mandrels 11 to the web 8. For this purpose, the anvil roller 52 is arranged relative to the bearing drum 39 in such a way that the claw ends 20 are flattened when the nip 53 formed between the bearing drum 39 and the anvil roller 52 is flattened. Since the threading mandrels 11 consist of a thermoplastic plastic, the flattening can be facilitated by heating the anvil roller 52.

After flattening (FIG. 5 in phase III), the claws 19 of the threading mandrels 11 essentially have the configuration shown in FIG. 10, part III, in which a firm connection between the threading mandrel 11 and the web 8 is created.

While the leaf sections not to be provided with a threading mandrel pass through the connecting device 34, the bearing drum 39, which can be controlled separately from the deflection rollers 41, is moved back to the starting position in which the slot 42 is in the position according to phase I in FIG. 5 .

In conclusion, it should be pointed out that in the winding device 38 a plurality of cloth windings 7 can be wound side by side directly next to one another. The threading mandrels 11 of a cloth roll grip 7 centrally in the adjacent cloth wrap 7. When the cloth roll 7 is ejected from the winding device 38, however, the cloth roll separates easily from one another, since the winding is not so tight that the inserting 13 of each threading mandrel 11 engaging in the adjacent cloth roll is held to a considerable extent.

Furthermore, when the dispenser box is sold for the first time, the cloth wrap 7 can be sealed in a soft film packaging 16 analogously to the refill 15, so that both cloth wraps for the first use and for refilling are packaged uniformly.

FIGS. 11 to 14 show an alternative embodiment of the object of the application, in which threading mandrels 11 'differing from the exemplary embodiment according to FIGS. 7 to 10 are used. The basic design of the threading mandrels and their attachment to the web 8 of the cloth roll 7 are unchanged from the previously described embodiment. Corresponding parts of the subject of the application are therefore provided with the same reference numerals.

Only the differences between the exemplary embodiment according to FIGS. 11 to 14 and the exemplary embodiment according to FIGS. 7 to 10 are to be explained in more detail below:

The threading mandrel 11 'uses claws 19' which essentially have the shape of a four-sided, oblique pyramid. Because of this shape, the claws 19 'arranged in a row in the longitudinal direction on the threading mandrel 11' have inclined flanks 54 which alternately point in opposite directions with respect to the row direction (see FIGS. 11, 12). When the claws 19 'are flattened using the manufacturing device discussed above with reference to FIGS. 4 to 6, the ends 20' of the claws 19 'are each bent alternately in opposite directions due to the inclined flanks 54 (see FIGS. 13, 14). This results in an even better anchoring of the threading mandrels 11 ′ on the web 8 compared to the exemplary embodiment according to FIGS. 7 to 9.
