Description

The invention relates to a dispenser for dispensing sheet material, in particular wet wipes, according to the preamble of claim 1, the invention also relates to a container for sheet material according to the preamble

of claim 7.

Wet wipes are usually offered in so-called flow packs. Such flow packs have, among other things, a packaging made of a thin, flexible plastic film in which the wet wipes are accommodated. There is a removal opening on the top that can be closed tightly to prevent the

avoid the wet wipes they contain.

Very simple dispensers into which such flow packs can be used are also known. Most of these dispensers have a spring-loaded plunger that presses on the packaging from below and thus pushes the wet wipes contained therein in the direction of the dispensing opening.

With such known simple dispensers, there is the problem of correctly positioning the relatively unstable, soft flow pack, which can lead to problems with the replenishment on the one hand and problems with tightness on the other hand.

The object of the invention is to provide an improved dispenser for dispensing sheet material, in particular wet wipes, and a container suitable for this purpose, in which the container can be positioned in the dispenser easily and precisely. In addition, it should be possible to avoid leaking problems as far as possible.

According to the invention, this is achieved by a dispenser having the features of claim 1 and by a container having the features of claim 7 .

The basic idea of the invention is to use the dimensionally stable body that is already present in the so-called flow packs as a connecting element to the dispenser and to use a simple sliding fit to create a simple and yet

establish a secure connection between the container and dispenser when refilling.

When the supply of wet wipes in the container has been used up, the empty container need only be pulled out of the sliding seat and a new container with filled wet wipes or other sheet-like material inserted

become.

Such a sliding fit also allows easy sealing to the dispenser if desired. In this case, the closure, which prevents the wet wipes used from drying out, can also be designed to provide a good seal as a dispenser cover on the dispenser instead of or in addition to a container cover.

The container itself can in turn have a container lid for closing, which prevents drying out when stored outside of the dispenser. Before inserting it into the dispenser, the container lid can be removed, for example by loosening a predetermined breaking point. Then the flow pack (the container) is pushed into the dispenser in the sliding seat and a dispenser lid provided on the dispenser can now assume the function of the tight closure.

In principle, it is also possible to design the sliding seat in such a way that it only carries out the correct positioning and the sealing function continues to be carried out by a container lid which is not attached to the dispenser but directly to the container and in particular to the dimensionally stable body of the same.

The sliding fit and its corresponding formation of projections or grooves on the container according to the invention also makes it possible to fulfill coding functions, for example by the projections on the container being specially designed.

An example would be characterized in that the dimensionally stable body has a bevel running obliquely to the longitudinal edge at least at one end of a longitudinal edge serving as a projection. Preferably there are two such symmetrically diametrically opposed bevels to enable the container to be held in both

Longitudinal directions or rotated by 180 ° can be used.

If the sliding seat now also has a stop surface corresponding to the bevel, a container can only be used if its bevel matches the stop surface of the container. Another container with a differently designed projection cannot then be inserted into the dispenser, or at least not in such a way that the necessary sealing function is provided. This can be achieved

that only correct refills are inserted into the dispenser.

For example, there may be dispensers for wet wipes that have such a bevel and other dispensers that contain, for example, disinfectant-soaked wipes that do not have such a bevel. This means that the container is always correctly assigned to the dispenser via the shape of the projections and the stops of the sliding seat.

Another possibility of coding in the above-mentioned sense, i.e. in the correct assignment of container to dispenser, can be achieved in that the dimensionally stable body - preferably on at least one transverse edge running transversely to the sliding direction - has at least one coding projection and/or at least one in the sliding direction open to the front

has coding exemption.

The coding projections or coding clearances are then a kind of key which may or may not fit into corresponding recesses or projections at the end of the dispenser's sliding seat. Only if the coding tabs or the

If the coding exemptions match the dispenser, the container can be used correctly.

Further advantages and details of the invention are based on the following

Fig. 10 shows an embodiment of a side of the sliding seat for a dispenser according to the invention.

11a, 11b, 11c show, in a schematic side view, an exemplary embodiment of the container according to the invention, a possible construction for a closable and tear-off container lid.

The exemplary embodiment illustrated in FIG. 1 is a container 1 which is designed as a so-called flow pack.

Such a flow pack consists essentially of a plastic film that is connected along a longitudinal connecting line 2 to form a tube, preferably welded or glued. This can be done via a not shown, fold-like connection.

The opposite tube sections are also connected to one another transversely to the longitudinal connecting line 2, namely along a transverse connecting line 3, in order to obtain a closed, flexible plastic container overall, which can be filled, for example, with wet wipes 4 or another sheet-like material, such as that in Figure 2 is shown.

In order to be able to remove the wet wipes 4, the container 1 has a dimensionally stable body 5 which is connected to the wall 7 of the

Container is connected.

In the center of the dimensionally stable body 5 is the actual removal opening 8 for the sheet material 4, for example wet wipes.

The dimensionally stable body 5, which can be made of plastic, for example, has a circumferential groove 9 on its upper side which, together with the likewise circumferential edge 10, forms a detachable receptacle in FIGS

cover shown can serve.

According to the invention, a projection 11 is now formed on the dimensionally stable body 5 of the container 1 and can be pushed into a sliding seat 12 of the dispenser 33 . In the present exemplary embodiment, there are two projections 11 that run in a sliding direction S. These projections are designed as protruding edges on the dimensionally stable body 5, laterally and radially outside of the adhesive points 6.

As FIG. 3 shows, these projections 11 of the dimensionally stable body 5 can now be inserted into a sliding seat 12 of the dispenser 33 by sliding in a direction that is perpendicular to the plane of the page in FIG. The sliding seat 12 is formed by two opposite, parallel grooves 13, which are dimensioned so that they can accommodate the projections 11 with as little play as possible, but still be able to be pushed in easily. In the area of this sliding seat 12, seals can also be provided, as will be described later in more detail with reference to FIG.

In the exemplary embodiment shown in FIG. 3, the dispenser 33 has an essentially closed housing 14, which has a filling opening for the container 1, which is not shown here. When the container 1 is pushed in, a plunger 15 then presses on the container 1 under the action of the springs 16 and thus pushes the wet wipes 4 located therein in the direction of the removal opening 8. When the container 1 is empty, i.e. there are no more wet wipes 4 in it, can

you can simply remove the container 1 from the dispenser 33 by pushing back the plunger 15 against the springs 16 and insert a new, filled container 1

insert.

As shown in FIG. 3, the dispenser can be set up horizontally, for example, by means of holding means 17 . However, it can also be provided that these holding means 17 are fastening eyelets or the like in order to fasten the dispenser to a wall in the vertical position, for example. Then the wet wipes are not removed upwards, but away from the wall to the side.

The sliding seat 12 in combination with the projections 11 allows easy refilling of the container 1 in the dispenser 33, with an exact positioning in the container 1 and dispenser 33 being given automatically. Sealing functions can also be carried out easily, for example in that the sliding seat 12 is formed in a sealing manner on the projections themselves through an appropriate choice of material and a tight fit.

There is also the possibility, as shown in FIG. 10, of attaching a separate seal 18 in the area of the sliding seat 12, namely at the bottom of the groove, in order to achieve a sealing function. Other ways of attaching the separate seal 18 in the area of the sliding seat are also entirely conceivable and possible. Finally, a possibility can be created to tightly seal the container 1 in the dispenser 33

hold.

In order to make it easier to slide the container 1 into the sliding seat 12, an insertion bevel 19 can be provided (see FIG. 10). An end stop 26 can be provided at the end in order to determine the exact insertion position of the container 1 in the dispenser 33 (FIG. 10).

There are various possibilities for the formation of the sliding seat itself. At

the embodiment shown in Figure 3 are parallel to the container 1 itself

Projections 11 have been formed, which in grooves 13 of the sliding seat 12 of the

71725

donors 33 have intervened. This situation is again shown schematically in Figure 4

shown.

Another exemplary embodiment is shown in FIG. Here too there are projections 11 which engage in a groove 13 of the sliding seat 12 . However, here the projections 11 lie laterally at some distance from the wall 7 on the dimensionally stable body 5, while in FIG. 3 and in FIG. 4 the projection 11 lies closer to the wall.

The exemplary embodiment illustrated in FIG. 6 is a “kinematic reversal”. Here 5 grooves 11a are formed on the dimensionally stable body, while the sliding seat itself is formed by projections 13a which engage in the grooves 11a.

FIGS. 7a, 7b and 7c show, in a plan view, exemplary embodiments of dimensionally stable bodies 5 which, in the sliding direction S, fit into a sliding seat of a dispenser

can be inserted.

In the exemplary embodiment shown in FIG. 7a, which essentially corresponds to the solution according to FIGS. 3 and 4, the plan view is essentially rectangular. The longitudinal edges form the projections 11.

In the exemplary embodiment shown in FIG. 7b, pairs of projections 11 are provided which project laterally beyond the normal longitudinal edge. Important for the function of a sliding seat is the fact that the widths D at the points A and B offset in the sliding direction, which are indicated by transverse double arrows

are located in both pairs of projections 11 are the same.

In the exemplary embodiment in FIG. 7a, too, this width, which is identified by a double arrow, is the same at two different points A and B, which are offset in the sliding direction S. In the example in FIG. 7a, there is a constant width at all

D provided.

In the exemplary embodiment illustrated in FIG. 8, a bevel 20 is also shown in a plan view of a dimensionally stable body of an exemplary embodiment of the container according to the invention. Specifically, there are two diametrically opposite bevels 20.

These bevels 20 interact with oblique end stops (not shown) in the area of the sliding seat of the dispenser and have the effect that the container belonging to the dimensionally stable body 5 can only be fully and correctly inserted into the sliding seat of the dispenser if a bevel 20 is actually present . If this bevel 20 were not present, for example as shown in FIG. 7a, the container cannot be pushed in completely and therefore not tightly due to the oblique stop in the dispenser. This can prevent the wrong containers from being used.

For the same purpose, i.e. for key-like coding of the container relative to the dispenser, it can also be provided that the dimensionally stable body — preferably on at least one transverse edge 21 running transversely to the sliding direction — has at least one coding projection 22 projecting forward in the sliding direction and/or at least one in Sliding direction has open coding exemption forward (Fig. 9).

As shown in FIGS. 11a, 11b and 11c, a container cover 23 can be provided with which the removal opening 8 of the container can be closed tightly. Figures 11a to 11c show only schematic representations. Sealing elements are well known to those skilled in the art, either through separate seals or through a precisely fitting closure, for example with circumferential projections and grooves,

similar to Figures 1 and 2.

The container lid 23 closed in FIG. 11a prevents the wet wipes contained therein from evaporating while being stored outside of the dispenser.

Shortly before use, the container lid 23 can, for example, be swiveled open about a film hinge 24 in the direction of arrow 25 in order to achieve an open position according to FIG. 11b.

In principle, the container lid 23 can also be used again in the dispenser itself for (re)closing the container 1 . Then the combination of the projections 11 of the container with the sliding seat 12 of the dispenser mainly has the

Function of the exact positioning of the container 1 in the dispenser 33.

However, the sealing function of the sliding seat can also be used in order to slide through the dispenser cover 23a mounted on the dispenser side, as is shown schematically in FIG

3 to achieve a tight seal.

It can be provided, as shown in Figure 11c, that the container lid 23 can be torn off, namely along a predetermined breaking point, for example in the area of the film hinge 24. The container lid 23 is then simply removed and thrown away and the dispenser lid 23a of the dispenser takes over after the insertion of the Container 1 in the sliding seat of the dispenser the locking function to prevent the

prevent wet wipes.

The dispenser cover 23a can be mounted on the dispenser in a wide variety of ways. FIG. 3 shows only schematically the dispenser cover 23a as such. For example, it is possible for the closure cover 23a to be articulated or pivotable on

To store dispenser 33 or its housing 14 . Circumferential projections 25 on the closure cover 23a of the dispenser 33 can

for example tightly engage in the circumferential groove 9 of the container, but other seals relative to the housing 14 of the dispenser are also quite possible.
