Description

donor

The invention relates to a dispenser for dispensing liquid to pasty masses, having a dispensing head having a dispensing head, a storage space and a dispenser head part, wherein the dispensing head relative to the

Dispenser headboard from a dispensing ready position in a lowered position or vice versa is movable.

The prior art is to refer to DE 10 2007 007402 Al for example. In the donor known from this, cf. For example, FIGS. 7 to 9 of this document, the dispensing head is fixedly connected to a pumping chamber part which can be pressed down for the pumping movement. The dispenser head can be shut down by a screwing motion to place the dispensing head with the dispensing mouth in a dispensing position.

The known dispenser is not yet satisfactory in terms of handling in all respects. On this basis, the object of the invention is to specify a dispenser which is easy to handle.

According to a first solution to this problem, it is provided that the dispensing head can be extended or retracted relative to the dispenser-fixed part, as a result of a support on a dispenser-fixed part during rotational drive through the dispenser-head part. It is realized an independent mobility of the dispenser headboard. As a result of the rotational movement of the dispenser head part, a movement of the dispensing head having at least one vertical component takes place, which for this purpose in turn is supported on the dispenser-fixed part.

Other features, as described below, may be important in the context of the concept described above, but also have independent significance or be essential in a summary of characteristics.

It is thus preferred for the dispenser head part to have a vertically accessible recess into which a protruding dispensing nozzle of the dispensing head enters and exits. In the retracted state, a favorable hiding position of the dispensing nozzle is achieved. This can also be used to close the dispensing nozzle.

It is preferred that the dispenser head part is rotatable relative to the storage container. A user can hold the dispenser to the storage container and then set by turning the dispenser head part, the desired position of the dispensing head.

Furthermore, it is preferred that the dispensing head is guided in relation to a designed as an adjustment part donor fixed part. The support of the dispensing head to the dispenser-fixed part is realized by the slotted guide. A cheap snap-in mounting is possible.

It is also preferred that the dispensing head overhangs a dispensing tube communicating with the pumping chamber. In this case, the dispensing tube is preferably firmly connected to an upper pumping chamber part, in particular the piston part. While the dispensing head, in the form of a sleeve, can be moved to the dispensing tube in a telecoupling manner.

In particular, it is preferred that the dispensing head in the extended position cooperates in alignment with a dispensing opening of the dispenser tube, but cooperates in the retracted position with a sealed portion of the dispenser tube. So is at the same time together with the entry and exit the dispensing head given a closure or opening of the mass output path.

The invention also provides a dispenser for dispensing liquid to pasty masses, as assumed at the outset, in which the dispenser is provided with a dispensing head that can be telescoped relative to a vertical non-movable dispensing head part, that the dispensing head has a radially protruding dispensing mouth, a recess is formed in the dispensing head part for receiving the dispensing mouth in a lower position of the dispensing head, into which lower position an upper edge of the dispensing head part extends over the same surface to a surface of the dispensing head.

In the following, the invention will be explained further with reference to the attached drawing, which, however, represents only one embodiment. Hereby shows:

Shown and described, first with reference to FIG. 1, a dispenser 1, which serves to dispense liquid to pasty masses. It has a dispensing head 3 accommodated in a dispenser head part 2 which at the same time forms the outer surface. The dispensing head 3 connects up to a pumping chamber 4, see Fig. 3, with an inlet valve 5 and an outlet valve 6. It can also be provided only a valve.

Below the pumping chamber 4 is a storage space 7, in which, for example, a follower piston 8 may be arranged. In the dispenser head part 2, a fixed verse part part 9 is further arranged, which has a Verstellkulisse 10, in which one or more link elements 11 of the dispensing head 3 run. The donation head part 2 is designed like a sleeve. It has a tubular shape with U wall formed at the upper end. The outer wall is in cross section via a U-web in an inwardly freely projecting Wandungssteg over. The U-web forms an outer, circular ring-shaped end face. In the region of the recess 35 for the dispensing mouth 25, the wall is preferably only angular, without inner U-legs, formed.

The dispensing head 3 is positively coupled to the dispenser head portion 2, which is rotatably supported relative to a dispenser sleeve portion 12. However, it is not vertically movable relative to the dispenser sleeve portion 12.

The rotational coupling between the dispenser head part 2 and the dispensing head 3 is achieved in detail by a driving projection 14 formed on the dispensing head 3, in the exemplary embodiment below the dispensing mouth 25, which engages in a respective receiving recess on the inside of the dispenser head part 2.

The pump chamber 4 is formed in a further detail by a fixed pump chamber lower part 15 and a pump chamber upper part 16, which is vertically movable in comparison.

The pumping chamber upper part 16 is composed in a further detail of a piston part 17 and a spring-engaging part 18 engaging in this latching manner. Against the spring stop member 18 acts a return spring 19 which is supported at the other end of the pump chamber lower part 15, outside the pumping chamber 4. Above the Pumpkammerauslassventiles 6 operatively connects to a dispensing tube 21, which partially by an inner surface of a cylindrical engaging portion of the spring stop member 18 and partially by a latched with the engagement portion 20, axially in Aus gaberichtung subsequent tube part 21 'is composed. The dispensing tube 21 is covered by the dispensing head 3. The tube part 21 'is in the embodiment, preferably by positive engagement, rotationally secured relative to the spring stopper 18. The spring stop member 18 at the same time ne an upwardly freestanding receiving sleeve 22, in which the head part 3 is telescopically received (see about comparison Fig. 3, 5 ). Next rotatably with the head part 3, an output closing part 23 is provided. The dispensing closure part 23 is also a part of the dispensing tube 21 as a continuation section, whereby it rotates together with the dispensing head 3 during a rotary actuation of the dispenser head part 2 relative to the stationary tube part 21 '. For this purpose, it cooperates with the tube part 21 'by means of a cylinder section 24. The cylinder portion 24 comprises the tube part 21 'on the outside. The angled continuation portion of the dispensing tube in the dispensing closure member 23 transitions into a horizontally extending dispensing nozzle 13 forming dispensing section, at the end of which the dispensing mouth 25 is formed.

The fixed receiving sleeve 22 further forms a gate path 26, in which a trained on the dispensing head 3 sliding block 27, see, for example, Fig. 6, runs.

The link path 26 is composed in detail of a sloping portion 28, a lower holding portion 29 and an upper holding portion 30 together.

Upon rotation of the dispenser head part 2 relative to the dispenser sleeve part 12 of the dispensing head 3 is entrained positively. As a result of the support of the dispensing head 3 by means of the slotted guide on the receiving sleeve 22 representing a donor fixed part, the desired vertical movement of the dispensing head 3 takes place. If in the extended position of the dispensing head 3 is rotated so that the sliding block 27 is in the upper holding portion 30, by pressing, so pressurizing the top of the dispensing head 3, a mass output can be achieved. For at the same time in this position, see, for example, Fig. 7, an aligned alignment between the opening 31 of the output end part 23 and the opening 32 of the tube 21 is given.

By contrast, in the retracted position, see for example FIG. 3, a displacement of the tube section 21 is achieved by a circumferential and vertical displacement between the openings 31, 32. In addition, the dispensing opening 25 having radial projection of the dispensing head 3 in a recess 35 of the dispenser head part 2 a. A movement of the dispensing head 3 down is prevented. This inlay can also be used as a muzzle closure.

In a further detail, the pumping chamber lower part 15 is screwed onto a reservoir part 33, see FIG. 3. The storage space part 33 is on the outside, at least over a part of its axial extension of the part 12 overlapped. In addition, it is over a lower part of its extension, wherein on the inside of the Vorratsraumteils a follower piston 8 is arranged, see Fig. 2, of a lower cap part 34 overlapped.

In the retracted position at the same time an upper edge of the donation head portion 2 is the same surface extending to a surface of the dispensing head 3. The surface may be a flat, perpendicular to a vertical axis of the dispenser surface. But it can also be, for example, according to the embodiment, see Fig. 3, slightly curved in cross-section formed running. In this case, a circular section-shaped cross section can be given. In this case with a radius which is a horizontal diameter of preferably preferably circular formed donor exceeds. However, the radius is more preferably less than five times the diameter.

In the embodiment of Figs. 9 to 11 is an upper edge of the dispenser head part 2 in the retracted state, Fig. 10, the same area, corresponding to a flat surface, extending to the surface of the dispensing head 3 is formed.

It is also important that the donor mouth 25 is retracted in the retracted state, Fig. 10, behind the wall area 36 of the donor head 2, which also terminates in the area of the donor mouth 25 in the end area. The wall portion 36 is not double-walled in this area, corresponding to the described U-shape, but only formed single-walled. Below the dispensing mouth 25, a wall region 37 of the dispensing head 3, which runs concavely in the illustrated cross section with respect to its outside, adjoins.

The dispenser top part shown in FIGS. 9 and 10 is also designed with regard to the storage container to form a docking connection, in the form of a latching or bouncing connection. In the above-described embodiment, it can be seen that this is a screw connection.

As can be seen in particular from FIG. 11, the adjustment gate 10 is closed on the upper side by a pull-out lock 38. The pull-out lock consists of a placed on the outer wall latch 39, from which downwardly and inwardly directed a barb portion 40 protrudes. During assembly of the dispensing head 3 of the sliding block 27 moves into the bar by the latch 39 only outside bridged opening of Verstellkulisse 10 and overflows here, with elastic deflection to the outside, the barb portion 40. After overrun the bouncing barb member 40 blocks a possible withdrawal of the dispensing head 3 from the adjusting part 9. Incidentally, for both shown embodiments it is of particular importance that in the course of an adjustment of the dispensing head 3 relative to the dispenser head part 2, ie a retraction or retraction, ie a change between the position according to FIG. 9 and FIG 3 and 7, no change in volume occurs in the discharge closure part 23 and the subsequent mass flow path leading to the donor mouth 25 on the one hand and in the tube part 21 or 21 'on the other hand. The mass, as it were opposite the tube part 21, 21 'during start-up and twisting or lowering and twisting, is merely sheared off or brought into alignment with the opening 32 of the tube 21 in order to be able to dispense it during a pumping movement.

It can further be provided, as is also shown in FIG. 11, that a projection is attached to the fixed adjusting part 9, which, upon rotation of the dispenser head part 2, extends circumferentially, inwardly projecting further projections, which are not shown in detail , overflows. This is to generate a sound, such as a clicking sound, which also indicates acoustically to the user the complete retraction or extension of the dispensing head 3.

In detail, as shown in FIG. 11, it may be an initially formed in the adjustment part 9 opening 41, on the inside of both an inwardly and outwardly projecting latch 42, to some extent elastically movable, is formed and further to It should be understood that the projections are arranged relative to one another such that the respective noise corresponds to the upper or lower end position of the dispensing head 3. All disclosed features are essential to the invention. The disclosure of the associated / attached priority documents (copy of the prior application) is hereby also incorporated in full in the disclosure of the application, also for the purpose of including features of these documents in claims of the present application.
