Holder for holding a filter bag

The present innovation relates to a holder made of an elastic material, in particular plastic, for holding a filter bag, consisting of an axially slotted nozzle provided with an integrally formed handle, the circumference of which can be reduced by means of a pressure piece located in the transition area to the handle and in the end area of the slot.

Owners of the aforementioned species are known.

The slotted nozzle can be reduced in size by exerting appropriate pressure on the pressure piece, so that a suitably sized filter bag can be placed on the nozzle. If the pressure on the pressure piece is released again, the nozzle's circumference increases again and the filter bag that has been pushed on is now held in place by the nozzle. In this case, there are often small barbs on the nozzle.

which serve to additionally fix the filter bag.

The disadvantage of the known holders is that the nozzle immediately springs back apart as soon as pressure is applied to the pressure piece. This causes handling disadvantages in that a user is forced to operate and hold the pressure piece with one hand, so that only one hand remains to place the filter bag on the nozzle.

For users who are specifically handicapped for this handling process, the known design is therefore unsuitable or unusable.

The aim of the present innovation is to improve a holder of the generic type using simple means so that it is easier to handle when attaching a filter bag to the nozzle.

To solve this problem, a holder of the generic type is proposed, which is characterized in that the pressure piece can be fixed to the handle.

This relatively simple measure ensures that after the pressure piece has been actuated and the circumference of the nozzle has been reduced, this position is initially secured, i.e. the user is now able to use both hands exclusively to push the filter bag onto the nozzle, whereby

where the holder can be placed on its mouth level,

Once this has been done, the pressure piece is released from the handle again so that the filter bag is then sufficiently secured.

A particularly useful embodiment is that the pressure piece can be snapped into a recess in the handle.

This is a useful and easy-to-implement measure, especially for holders made of plastic.

Another idea behind the innovation is that the pressure piece has a locking lug on its end facing away from the nozzle, which, when the pressure piece is locked in place, engages behind a web that delimits a locking recess in the handle.

In order to facilitate the release of the locking position of the pressure piece, a further idea of the innovation is that in the transition area between the nozzle and the pressure piece on the nozzle or on a hollow ring flange formed on the upper end of the nozzle at least one notch, knurling or the like running exparallel to the nozzle is provided.

This notch, knurling or similar makes it much easier to release the locking position of the pressure piece, since this notch, knurling or similar is used as a finger hold when releasing the locking position.

An example of the innovation is shown in the attached drawing and is described in more detail below. They show:

Fig. 1 a perspective view of a new holder with filter bag

Fig. 2 a view of the holder in the direction of arrow II in Fig. 1

Fig. 3 is a partial view in the direction of arrow III in Fig. 2.

The holder for holding a filter bag 11 shown in Fig. 1 and 2 and provided with the reference number 10 consists in a manner known per se of an axially slotted nozzle 12 and a handle 13 integrally formed on this nozzle 12.

The circumference of the nozzle 12 can be reduced by a pressure piece 14, which is located in the transition area between the nozzle 12 and the handle 13 and in the end area of the slot 15, so that a correspondingly dimensioned filter bag 11 can simply be pushed onto the nozzle 12.

According to the present innovation, the pressure piece can be fixed in the handle 13, i.e., the pressure piece 14 can be moved after its actuation and the associated reduction

of the circumference of the nozzle 12 in this position on the handle 13. This makes it easier for a user to slide a filter bag 11 onto the nozzle 12, since both hands are now available for this.

A preferred embodiment is one in which the pressure piece 14 can be locked into a recess in the handle 13. This is preferably achieved in that the pressure piece is provided with an integrally formed locking lug 16 at its end facing away from the nozzle 12, which, when the pressure piece 14 is locked in place, engages behind a web 18 delimiting a locking recess 17 in the handle 13.

In the transition area between the pressure piece 14 and the connector 12 or a hollow ring flange 19 formed on the upper end of the connector 12, notches 20 running axially parallel to the connector 12 are provided, which make it easier to release the locking position of the pressure piece 14. Instead of the notches 20, knurling or other profiles forming a finger grip could also be provided.

The connecting piece 12 is provided with a connecting web 21 in its lower end region on the side facing away from the handle 13, by which the axial slot is interrupted. This results in a certain stiffening, which promotes the springing of the ratchet nose 15 into the locking recess 17.

The area in which the connecting web 21 is provided is conically tapered, as is the lower end area of the nozzle 12 facing the handle 13, whereby sliding a filter bag onto the nozzle is made considerably easier.

The holder 10 is made entirely of plastic in a known manner.
