The invention relates to an adapter for a product dispenser and a product dispenser for outputting a medium.
A product dispenser for outputting a medium is known from EP 1 242 295 B3. This product dispenser comprises a valve, which closes a container opening of a pressure container for receiving a medium to be output. Associated with the container opening an adapter is provided, which has an actuating lever for controlling the valve. The actuating lever is attached by way of a swivel arrangement on the adapter, wherein the actuating lever is transferable from a starting position, in which the valve is closed, by a swivel movement into an active position, in which the valve is operated to output the medium.
Another product dispenser for outputting a medium from a pressure container is known from DE 20 2009 018 628 U1. This product dispenser comprises an actuating lever with a handle arranged thereon, which is positioned rotating about a longitudinal axis of the valve output opening. Due to the rotating arrangement of the swivel lever about the longitudinal axis of the valve output opening, a product discharge rate can be adjusted continuously between a maximum rate and a minimum rate. To output the product, the actuating lever can be swiveled in the direction of the pressure container in order to release the valve into an active position for outputting the medium as a function of the set discharge rate.
A product dispenser for outputting a medium from a pressure container is known from JP 2004-188 074 A1. This product dispenser comprises an output valve with an actuating handle arranged thereon. To output the medium, the actuating handle can be pressed, wherein the valve output opening, which is connected by a web to an annular connection section, is actuated by a swivel motion.
The object of the invention is to propose an adapter for a product dispenser with an adapter base body for positioning the adapter on a container opening of a pressure container, which permits simple actuation for outputting a medium from the pressure container.
This object is achieved by an adapter for a product dispenser in which the output sleeve is connected movably to the adapter base body by an elastic connection. The elastic connection between the output sleeve and the adapter base body is formed as an annular or disc-shaped membrane, which extends lying in between. It is made possible by this that the output sleeve, which engages a valve of the pressure container with the output sleeve following positioning of the adapter on a container opening of a pressure container, is variable in location or position along a longitudinal axis of the adapter base body. A guided displacement movement of the valve can take place due to this elastic connection. The output of a medium from the pressure container can be controlled in a simple manner by this. Furthermore, a high number of operations can be facilitated.
It is preferably provided that the output sleeve is arranged in a self-retaining manner in a starting position relative to the adapter base body and the output sleeve is transferable by an impact force at least partly along the longitudinal direction of the adapter base body into an active position. This has the advantage that an output of the medium from the pressure container is enabled only in the case of active operation of the adapter and the starting position of the adapter assumes an NC position (Normally Closed position). An unintentional output of the medium can be prevented by this.
The elastic connection further has the advantage that on transfer from the starting position to the active position, a reset force is built up, so that following the output of a medium and release of the impact force on the output sleeve, an autonomous reset of the output sleeve into the starting position takes place.
The adapter base body preferably comprises a flange aligned coaxially with the longitudinal axis, wherein extending between the flange and the output sleeve is an end face, which is inclined with respect to the longitudinal axis and the elastic connection is provided between the end face and the output sleeve. This permits a simple structural linkage of the output sleeve to the adapter base body and a configuration of the elastic connection arranged in between. In a starting position of the output sleeve relative to the adapter base body, the end face and the elastic connection are preferably arranged in a common plane. Due to this, on transfer of the output sleeve to an active position, the elastic connection is pressed inwards with respect to the inclination of the end face, whereby the reset force is generated. A snap effect can be achieved by this, which facilitates the autonomous return of the output sleeve to the starting position relative to the adapter base body.
Provided inside the flange of the adapter base body is preferably an attachment section, which extends at least in sections along the flange and can be attached on an edge of the pressure container by a latching and/or snap connection. Simple placement and pressing of the adapter base body on the edge of the pressure container is sufficient for its attachment. Fast assembly is created by this.
The attachment section on the flange of the adapter base body preferably has several webs formed at a distance from one another, which with the circumferential flange form a U-shaped engagement area, by which the attachment section engages in a positive locking manner on the edge of the container base body. The attachment section can be configured cost-effectively.
Provided on the output sleeve of the adapter in the direction of placement onto the pressure container is a connection, which engages on a valve of the pressure container. A reduction in components can be achieved by this.
The output sleeve of the adapter has a receptacle for a nozzle lying opposite the connection. This can be screwed on interchangeably.
It is preferably provided that at least the adapter base body, the output sleeve and the elastic connection are formed in one piece. Manufacturing costs are reduced and the assembly effort simplified by this.
At least the adapter base body, the output sleeve and the elastic connection are preferably manufactured as a plastic injection-molded part. For example, the adapter can be manufactured from a thermoplastic elastomer, in particular polypropylene, polyethylene or similar.
The invention and other advantageous embodiments and developments of the same are described and explained in greater detail below by means of the examples depicted in the drawings. The features to be gathered from the description and the drawings can be applied according to the invention individually or in groups in any combination. The figures show:
In
The adapter base body 19 also has an output sleeve 25, onto which a nozzle 26 can be attached, in particular screwed. The nozzle 26 can be exchanged thereby. A closure 27 is provided on a front end of the nozzle 26 to prevent the medium in the nozzle 26 from drying out.
Furthermore, a cap 29 is provided, which substantially encloses the adapter 18. This cap 29 has a recess 31, through which the actuating lever 21 is led out, so that the handle 22 is positioned outside the cap 29.
In
An area of the recess 31 in the cap 29 is closed by a tamper-evident closure 32. This tamper-evident closure 32 is positioned in the recess 31 by several strut-like connections 33. The tamper-evident closure 32 can be released on at least two strut-like connections 33 to the recess 31, so that the quality closure remains loose and/or swivellable in the recess 31. The strut-like connections 33 form a predetermined breaking point in this case. The opening 30 can make the release of the tamper-evident closure 32 easier in that a tool can be introduced. If the tamper-evident closure 32 is missing, the user can clearly recognize that the product dispenser 11 had already been opened or used.
This valve 16 can correspond to the embodiment that is described, for example, in DE 10 2008 051 888 A1, to which reference is made in full.
The adapter 18 can be placed onto the container opening 14. This adapter 18 is shown in perspective in
An end face 45 extends between the flange 44 and the output sleeve 25. Connected to the end face 45 and the flange 44 there is provided an attachment section 46, which extends along the flange 44, at least in sections. The attachment section 46 comprises webs 48, which are provided at a distance from the flange 44 and form a take-up area lying in between. On the lower edge of the flange 44, pointing in the direction of the longitudinal axis 38, a latching lug 54 is provided. An attachment section 46 can be formed thereby, which can engage around the beading or an edge 47 of the container opening 14 or of the pressure container 12 in a latching manner. A latching, clamping or snap connection can preferably be provided.
Also provided on the flange 44 of the adapter base body 19 on an outer circumference is a latching element 42, which forms a releasable latching connection with a latching element 43 on an inner side of the cap 29. The cap 29 can thereby be clipped onto the adapter.
The adapter base body 19 further comprises the output sleeve 25, which is connected by an elastic connection 49 to the adapter base body 19. The end face 45 extends between the adapter base body 19 and the output sleeve 25. Viewed in a sectional representation, this end face 45 is oriented in a roof-shaped manner. The end face 45 covers the attachment section or abuts this.
The elastic connection 49 extends between the output sleeve 25 and the end face 45. In a starting position 68 the elastic connection 49 and the end face 45 lie in a common plane.
The elastic connection 49 is formed by an elastic membrane, which according to the embodiment depicted extends fully between the end face 45 of the flange 44 and the output sleeve 25. Due to this elastic connection 49, the position of the output sleeve 25 is variable along the longitudinal axis 38 with respect to the adapter base body 19. In particular, the output sleeve 25 is movable from the starting position 68 shown in
Furthermore,
To actuate the output sleeve 25, at least one actuating element 56 on the actuating lever 21 can engage on these cams 57 of the output sleeve 25. This actuating lever 56 is depicted, for example, in
The receptacle 52 on the output sleeve 25 is delimited by an annular collar 58, so that after the nozzle 26 is put on it assumes a defined position. A projection 59 is provided from this annular collar 58 in the direction of the elastic connection 49, which projection protrudes in the form of a web with respect to the outer circumference of the output sleeve 25 and is arranged at a distance from the elastic connection 49. This projection 59 forms a portion of a transportation lock of the actuating lever 21 and handle 22, as will be discussed below in
The adapter 18 is preferably formed in one piece with regard to its components depicted in
Reference is made to the description of
Alternatively to a circumferential elastic connection 49, several webs extending radially outwards with gaps formed in between can also be provided.
The slots 63 formed on the actuating lever 21 have an angled contour. The actuating lever 21 with the handle 22 is held thereby in one arrangement in the first end position 71 close to the pressure container 12. In an unlocked position 67 of the actuating lever 21 and handle 22, these can be moved further away with respect to the adapter base body 19 both in the direction of the longitudinal axis 38 and laterally to the longitudinal axis 38, in order to permit a reliable actuation of the handle 22 for outputting the medium.
The unlocked position 67 of the actuating lever 21 is shown in
In
As soon as the handle 22 is no longer operated, the actuating lever 21 with the handle 22 returns autonomously from the active position 69 to the starting position 68. This autonomous transfer to a closed position is produced by the reset element 39 of the valve 16.
In the active position 69 and starting position 68 the actuating lever 21 is arranged in the second end position 73 of the swivel arrangement 23. In this second end position 73, the actuating element 56 is positioned relative to the projection 59 so that in the swivel movement of the handle 22, the output sleeve 25 can be moved along the longitudinal axis 38 towards the pressure container 12.
This is to be recognized by a deflection 50 of the elastic connection 49, which extends between the output sleeve 25 and the annular adapter base body 19.
The adapter 18 can be provided as a sales unit. The actuating lever 21 is mounted on the swivel axis 62 and forms a fixed swivel arrangement. The cap 29 can be attached additionally to the adapter base body 19. To fit the cap 29, the handle 22 and the actuating lever 21 are led through the recess 31 of the cap 29 and then the cap 29 is connected to the adapter base body 19, in particular latched. This assembly unit can subsequently be connected to the container opening 14 of the pressure container 12 by a clip or latching connection with the circumferential edge. The nozzle 26 can be optionally screwed on to complete the product dispenser 11.
