Description

The invention relates to a dispenser according to the features of the preamble of claim 1.

A donor of the type in question is for example from the WO 2009/127651 A1 known. Also, a dispenser for dispensing liquid to pasty masses from the WO 2012/126920 A1 known.

From the WO 90/14897 A a dispenser with the features of the preamble of claim 1 is known. In this case, an eccentrically extending to the axis of rotation cylinder part is provided, through which extends the vertical tube section directly into the pumping chamber.

From the WO 2009/063518 A1 is an eccentrically movable mouth section known. The passage of mass from the central tube takes place in a first displacement position of the mouth section, while in a second displacement position the mass path is deported. From the WO 2008/056077 A2 is known in a dispenser to form a tubular flexible dispensing tube with a central transition to a pumping chamber outlet. The WO 2012/074162 A1 describes a dispenser with a centrically connected dispensing tube whose flexible mouth section can be shortened or extended by turning the dispenser head. The WO 2012/074163 A1 discloses, in one embodiment, a dispenser having an eccentric port of a dispensing tube, wherein the entire upper dispensing part is integrally formed with an eccentrically opening terminal portion. The JP-S-62-199161 U discloses a dispensing tube on a dispenser with a telescoping horizontal member.

Based on the stated prior art, the invention has for its object to provide an advantageous dispenser with an eccentric vertical tube section.

This object is achieved in the subject matter of claim 1, wherein it is pointed out that the vertical tube section adjoins an eccentric part and the eccentric part has a connection collar extending concentrically to the axis of rotation.

It is an independent displacement of the donor mouth having muzzle part realized relative to the dispenser headboard. The mouth part can thus be moved from a first position to a second position (dispensing standby position) or vice versa. This is preferably a sliding displacement of the mouth part.

The mouth part is in the course of a rotation of the dispenser head part from the first position to the second position, the radially outer position, movable. Preferably, it is movable only by the rotation of the dispenser head part. There is a coupling of the donor head part twisting around the travel axis with the radial movement of the muzzle part. By rotating the dispenser head part is forced to the radial displacement of the mouth part. The radial movement during a rotation of the dispenser head part in the second position (dispensing standby position) causes a displacement of the mouth part from a radially inner to a radially outer position. In this radially outer position, in particular, the end of the mouth part having the dispensing mouth can, by way of handling, survive over a circumferential outer wall of the dispenser head part.

A reverse rotational displacement of the dispenser head portion in the first position causes a corresponding return displacement of the mouth part from a radially outer position to a radially inner position.

The mouth part continues radially inward into a tube section extending substantially at right angles to the travel axis. Preferably, the mouth part is integrally formed with the tube portion and / or material.

The tube portion may be arranged such that its central axis with respect to a plane oriented perpendicular to the axis of rotation encloses an acute angle of up to 30 °, for example 10 or 15 °, to a radial.

The tube section merges into a vertical tube section extending in the direction of the travel axis relative to the travel axis. Preferably, the vertical tube section extends perpendicular to the opening in the mouth part tube section.

The tube portion and the vertical tube portion may be made in one piece and of uniform material, so in particular formed as hard plastic part.

The vertical tube section extends eccentrically to the axis of rotation along an axis parallel to the axis of the eccentric axis.

In one embodiment, the vertical tube section is rotatably provided about the eccentric axis. The rotatability about the eccentric axis may be limited, for example to a rotation angle of up to 90 °, further for example 5 °, 12 ° or 28 °. Also in this regard, a complete rotation through 360 ° relative to the eccentric axis is possible.

Also, the vertical tube section may be rotatable about the axis of rotation. In the given eccentric arrangement, the vertical tube section is therefore rotatable about the eccentric axis and / or about the axis of rotation.

The vertical tube section connects to the eccentric part. The eccentric can be rotatably connected to the vertical tube section, whereby a rotation of the vertical tube section about the eccentric axis via a rotation of the Exzenterteils. Also, the vertical tube section, as preferred, be rotatably connected to the eccentric part, so that the vertical tube section and eccentric part to each other and further the eccentric part relative to the donor head part are drehverlagerbar.

The eccentric part preferably has a pump chamber connection section extending concentrically with respect to the axis of rotation and an attachment section aligned eccentrically to the rotation axis for the vertical tube section.

The eccentric part has the connection collar which extends concentrically to the axis of rotation, in particular for cooperation with a bearing surface of the dispenser head part.

The mouth part may be guided on a non-rotatable dispenser part. Thus, a part of the slotted guide may be formed in a displaceable fixed with a pumping chamber part dispenser part. This dispenser part is preferably displaceable together with the pump chamber part from the second position (dispensing standby position) into a mass dispensing position in the direction of the travel axis.

At the mouth part, a sliding block may be formed and on the dispenser part a backdrop. Also, a sliding block and at the mouth part a corresponding backdrop may be formed on the dispenser part. Preferably, the scenery is arranged eccentrically to the axis of rotation. In cooperation with the engaging in the backdrop sliding block a positively driven radial displacement of the sliding block having muzzle part is brought about in a rotation of the sliding block about the axis of rotation relative to the backdrop.

The actuating part is displaced out of the second position in the direction of the travel axis for mass output, this preferably with entrainment of a part of the slide guide forming donor part and the pumping chamber part. For this purpose, the actuating part preferably has an actuating surface, which is preferably offered ergonomically favorable on the ceiling side of the dispenser.

The mouth part may be guided on the actuating part for radial mobility, for example, the mouth part in the direction of displacement laterally flanking actuating sections. Also, a guide can be achieved, for example in the form of a tongue and groove connection, which allows the radial movement of the mouth part relative to the actuating part.

The radial mobility of the mouth part may be limited radially outward and / or radially inwardly stop, for example, according to abutting transverse to the direction of displacement abragender mouthpiece sections against areas of the actuating member. The attacks can also be given via the slotted guide or according to training stop areas on the actuating part.

A dispensing tube connecting a pump chamber to the mouth part is provided. Through the dispensing tube, the material stored in the dispenser exits through the mouth of the dispensing nozzle when the dispenser is actuated accordingly. The described tube section and / or the vertical tube section are part of such a dispensing tube.

Due to the preferred guidance of the mouth part on the actuating part, the mouth part carries out a rotary movement of the actuating part. The dispensing tube may be rotatably arranged on a receiving part extending along the travel axis and / or axis of rotation relative thereto. At least a portion of the dispensing tube is rotatably disposed about the axis of travel and connected via the receiving part with the pumping chamber. The receiving part is designed as an eccentric part.

The dispensing tube may be a hard plastic tube, which is further preferably telescopically formed in a further section for enabling the radial mobility of the mouth part.

The dispenser preferably rotatably supports the operating part with respect to the travel axis, but immovably in the direction of the travel axis. It is a relative Drehverlagerbarkeit between actuator and dispenser part allowed, in the direction of the travel axis, i. in a shift from the second position to the mass output position and vice versa, there is a preferably uniform axial displacement.

The actuating part may preferably have a locking projection extending in the direction of the travel axis with respect to the travel axis opposite the mouth part. This lead works in the first position (locking position) of the dispenser head part with a dispenser-fixed stop member together. The actuating member is not displaceable along the axis of travel in this first position according to the support.

A rotational displacement of the dispenser head part together with the actuating part causes a corresponding displacement of the projection in the second position, in which position the locking projection of a retraction in the dispenser-fixed area opposite. The retraction recess allows the displacement of the dispenser head portion along the travel axis, upon immersion of the locking projection in the Einrahraussnehmung.

Shown and described, first with reference to FIG. 1 , a dispenser 1, which serves to dispense liquid to pasty masses.
The dispenser 1 has a dispenser head part 2. In the dispenser head part 2, an operating part 3 is received. Especially in an in FIG. 1 shown in the first position (locking position) of the dispenser 1, as well as in a dispensing standby position resulting second position according to FIG. 5 . the dispenser head part 2 and the actuating part 3 at the same time form an outer surface of the dispenser 1.

Part of the dispenser head part 2 is further a pumping chamber lower part 4. This forms centrally a pumping chamber 5, with an inlet valve 6 formed in the pumping chamber bottom.

The pumping chamber lower part 4 cooperates with a pumping chamber upper part 7 movable along a travel axis x relative to the pumping chamber lower part 4. The pumping chamber upper part 7 bears in the region of an end immersed in the pumping chamber 5 and sealed against the inner wall of the pumping chamber 5 an exhaust valve 8. The pumping chamber upper part 7 carries for this purpose a projecting into the pumping chamber 5, the outlet valve 8 exhibiting piston member 15th

The travel axis x preferably runs parallel to a donor body axis. Overall, the dispenser 1 is formed substantially rotationally symmetrical to this donor body axis.

Rotational and sliding firmly with the pumping chamber upper part 7, a dispenser part 9 is further provided in the form of an adjustment. This dispenser part 9 forms an upwardly in the direction of the actuating part 3 open scenery 10 a slide guide 11th

As shown in FIG. 4 is the backdrop 10 formed by a molded on a donor blanket 12 border, which in accordance with a floor plan FIG. 4 approximately along a circular section line runs whose center further with reference to the plan view in FIG. 4 lies outside of the donor-body axis point-like here.

In the area of the walled scenery 10, the donor blanket 12 is preferably broken.

The relatively rotatable and displaceable dispenser part 9 and pump chamber upper part 7 are displaceable together against a restoring force in the direction of the pump chamber lower part 4.

To reset a return spring 13 is provided in the form of a cylinder compression spring, which is supported at one end on the underside of a spring stop shoulder 14 of the pump chamber upper part 7 and the other end to the pumping chamber lower part 4 outside the pumping chamber 5.

The dispenser head part 2 further comprises a sleeve-like gripping portion 16. This goes over into an interrupted by the operating part 3 ceiling 17th

The gripping portion 16 is rotatably supported in particular with respect to the pumping chamber lower part 4 and the pumping chamber upper part 7 with the piston part 15 about an axis of rotation y receiving the dispenser body axis and aligned parallel to the travel axis x. However, it is not vertically movable relative to the lower and upper parts of the pumping chamber 5 and the dispenser part 9. Next, the gripping portion 16 is rotatably connected to the dispenser part 9.

Between the gripping portion 16 and the dispenser part 9, the actuating part 3 is received.

In essence, the actuating part 3, an actuating surface 18 forming an actuating surface, which passes through the gripping portion 16 in the ceiling 17 upwardly exposed.

The actuating cover 18 merges into a locking projection 19 extending radially inward of the gripping section 16. This extends with reference to a vertical sectional view according to FIG FIG. 3 essentially perpendicular to the actuating cover 18 in the direction of the pumping chamber lower part 4.

On the pump chamber lower part 4, a stop member 20 is formed with respect to a projection of the locking projection 19 along the axis x in the locking first position.

The stop member 20 extends beyond an upper peripheral edge of the pumping chamber lower part 4 freely upwards, this preferably over a circumferential angle of 10 to 30 °.

The operating part-side locking projection 19 extends in the circumferential direction over an angle of 10 to 60 °.

In the first position according to the representations in the FIGS. 1 to 4 extends the locking projection 19 above the stop member 20, preferably a downwardly facing edge of the locking projection 19 abuts against the stop member 20. A vertical displacement of the actuating part 3 relative to the dispenser head part 2, in particular to the pumping chamber lower part 4 is thus prevented.

With respect to the travel axis x opposite to the locking projection 19, a mouth portion 21 is provided. In this open donor mouth 22 is formed to the outside.

The mouth part 21 goes inside the dispenser head part 2, below the operating cover 18 of the operating part 3 into a dispensing tube 23, which is connected at the other end to the outlet-side region of the outlet valve 8 within the piston part 15.

The dispensing tube 23 is essentially made up of a tube section 37 extending radially inward and substantially at right angles to the axis of travel x or to the axis of rotation y and extending from the mouth section 21, and a vertical tube section 38 extending substantially in the direction of the axis x or axis of rotation y together.

The mouth part 21 is movable relative to the actuating part 3, moreover also relative to the dispenser part 9 transversely to the travel axis x.

For this purpose, the mouth part 21 is guided on the actuating part 3 for radial mobility. On the actuating part 3, the actuating cover 18 are two underside, the mouth portion 21 flanking wall sections 24 integrally formed.

At the mouth part 21, a sliding block 25 is formed. This engages in the slot 10 of the dispenser part 9.

Further, the mouth portion 21 in the first position of the dispenser head portion 2, for example, as shown in FIG FIG. 3 , displaced radially back into a position in which the opening plane of the dispensing outlet 22 behind an opening plane of a, the radial displacement of the mouth part 21 outwardly permitting cutout 26 in the region of the gripping portion 16 is located.

The cutout 26 flanked in the circumferential direction of the mouth part 21, provides the same in the course of a radial displacement of the mouth part 21 an additional guide.

Considered in the direction of the travel axis x below the dispensing mouth 22, a beard-like or flap-like arm 27 is integrally formed on the mouth part 21, which in the first position dips into a correspondingly downwardly widened region of the cutout 26 in the gripping section 16.

Below the pumping chamber 5, a reservoir 28 is provided. In this, a follower piston 29 may be arranged.

The storage space 28 is encompassed by a sleeve-like storage space wall 30 with a storage space bottom 31. In the arrangement of a follower piston 29, this works against the inside of the storage space wall 30.

The storage space wall 30 preferably has an outer diameter corresponding to the gripping portion 16 of the dispenser head part 2, so that the overall result is a circular cylindrical shape with the diameter of the dispenser 1 at least approximately constant over the height.

The dispenser head part 2 is connected as a unit to the stock part having the mass. In particular, the dispenser head part 2 is bounced onto the storage part, in particular in a cooperation region of the pump chamber lower part 4 and the storage space wall 30.

In the locking first position, as in detail, for example, from the FIG. 3 can be seen, the actuating member 3 is according to the support thereof by means of a locking projection 19 on the dispenser-fixed stop member 20 against a linear displacement in the direction of the axis x secured. A pumping movement and thus a mass output is thereby prevented.

For the output of mass is first to obtain the second position (donation-ready position) according to the representations in the FIGS. 5 to 8 required.

By detecting the sleeve-shaped gripping portion 16 and rotational displacement of the same relative to the non-rotatably connected to the pumping chamber lower part 4 and this connected to the supply part dispenser part 9, the actuating part 3 according to the positive reception of the actuating member 3 in the gripping portion 16 is entrained. The operating-part-side locking projection 19 leaves the area of the dispenser-fixed stop member 20 and is displaced into a region which allows the downward displacement of the actuating member 3 in the direction of the travel axis x.

In the course of the rotational movement of the gripping portion 16 and the actuating part 3 also runs the sliding block 25 in the backdrop 10. The slotted guide 11 provides a rotation stop both to define the first position (locking position) and to define the second position (donation-ready position).

According to the interaction of sliding block 25 and gate 10, the rotational movement of the actuating member 3 is superimposed by a sliding displacement of the mouth part 21 from radially inward to radially outward, after which in the second position the dispensing orifice 22 by a dimension a on the opening plane of the cutout 26 radially outward projects.

The dimension a corresponds in the illustrated embodiment one twentieth to one tenth of the maximum donor outer diameter b. In In another embodiment, the radial displacement dimension of the mouth part 21, for example 0.7 to 1.5 times, further corresponds to, for example, 1 times the inside diameter of the dispensing tube 23.

The rotational displacement from the first position to the second position and vice versa takes place in particular over an angle of 40 to 80 °, in particular 60 °.

In the second position, the locking projection 19 of the actuating part 3 is opposite to an insertion recess 32 of the rotationally fixed and beyond x in the direction of the axis x not displaceable pumping chamber lower part. 4

The dispensing tube 23 is preferably, as also shown, formed as a tube part, in particular as a soft plastic tube part.

The dispensing tube 23 is also designed to be elastically deformable, so as to be able to follow the relative rotation of the mouth part-side end relative to the piston part side connected end. In addition, the radial displaceability of the mouth part 21 can be understood especially in a tubular design of the dispensing tube 23.

From the second position out is lowering the operating part 3, in particular finger pressure on the operating ceiling 18, with entrainment of the pumping chamber upper part 7, the mass on the dispensing tube 23 and the dispensing outlet 22 can be dispensed.

A bead-like depression, which surrounds the cutout 26 in the gripping section 16, facilitates the removal of the mass discharged via the dispensing orifice 22.

Alternatively, the dispensing tube 23, as exemplified in FIG FIG. 12 shown, associated with the piston member 15 and rotatably supported relative to the piston member 15. For this purpose, on the piston part 15 or on the pumping chamber upper part 7, a receiving part 33 extending along the axis x is formed, in which the associated free end of the dispensing tube 23 engages. This free end of the dispensing tube 23 cooperates with a piston-like portion 34 with the inner wall of the receiving part 33. The piston-like portion 34 allows rotation of the dispensing tube 23 relative to the receiving part 33, while maintaining the necessary seal between dispensing tube 23 and receiving part 33rd

To enable the radial mobility of the dispensing tube 23 in the course of the radial displacement of the mouth part 21, the dispensing tube 23, in particular in the area facing the mouth part 21 telescopically as shown in FIG FIG. 13 be educated.

For example, in connection with a piston-part-side configuration of the dispensing tube 23 as shown in FIG FIG. 12 So is a non-elastically deformable dispensing tube 23 providable. The rotational and / or radial displacement can also be achieved by a knee-lever-like configuration of the dispensing tube 23 beyond.

The FIGS. 14 and 15 show a further alternative embodiment of the connection of the dispensing tube 23 to the pumping chamber upper part 7 and via this to the piston part 15th

For this purpose, the pumping chamber-upper part-side receiving part 33 has a ceiling, with an upwardly open, central opening, which merges into a channel 36 directed radially outwards as far as the wall of the receiving part 33.

This radial channel 36 is connected to a lateral, axially aligned branch channel, which ultimately opens into the interior of the piston part 15.
Through the cover-side opening, the free end of the dispensing tube 23 dives. This has a radial opening 35 in the tube wall, which extends in the plane of the radial channel 36 of the receiving part 33.
With rotation of the gripping portion 16 and thus of the actuating part 3, the dispensing tube 23 is rotated about the dispenser axis, ie about an axis aligned parallel to the axis of travel x to a position in which the opening 35 is aligned with the radial channel 36 for possible mass passage.

The FIGS. 16 to 20 show an embodiment in particular of the dispenser head part 2.

This has a cooperating with the pumping chamber upper part 7 eccentric part 39.
The eccentric 39 has a, the area of the spring stop shoulder 14 of the pump chamber upper part 7 passing through and substantially into the space of the piston member 15 opening riser 40. This is arranged centrally to the rotation axis y. The riser 40 extends vertically up to a pot-like recessed portion of the dispenser part 9. In the direction of the actuating part 3, the riser 40 has a riser ceiling 41.

The riser 40 is further radially outwardly surrounded by a relation to the rotation axis y radially aligned connection collar 42. By means of the connection collar 42, the riser 40 and thus the eccentric 39 is supported on the facing surface of the cup-like recess of the dispenser part 9.

At a radial distance from the axis of rotation y, a tube connection 43 is formed on the upper side of the connection collar 42 (seated thereon). In particular, its inner diameter is preferably adapted to the free inner diameter of the riser 40.

The eccentric axis z of the tube connection 43 runs parallel to the axis of rotation y and is preferably positioned such that the tube connection 43 partially cuts the riser tube 40 with reference to a plan view in which the tube connection 43 forms a circular line.

The tube connection 43 is closed vertically downwards through the connection collar 42 and opens up vertically upwards.

As a result of the intersection of riser 40 and tube connection 43, a radial opening 44 results between them, through which radial opening 44 in the mass output mass is conveyed from riser 40 into tube connection 43.

The tube port 43 receives a vertical tube portion 38 of the dispensing tube 23.

Preferably, directly above the tube connection 43, the vertical tube section 38 merges into a tube section 37 which is oriented perpendicular thereto, in particular radially aligned, and which forms the mouth part 21 at the end.

On the underside of the tube section 37, a sliding block 25 is formed, which engages in a formed on the pumping chamber upper part 7 and the dispenser part 9 slide 10.

According to rotation of the gripping portion 16 about the axis of rotation y in this embodiment, the mouth part 21 and about this the dispensing tube 23 according to the positive reception of the mouth part 21 in the operating part 3 is entrained. The rotational movement is due to the interaction of sliding block 25 and gate 10 superimposed by a sliding displacement of the mouth part 21 from radially inward to radially outward.

This radial displacement is in the described embodiment, in which the dispensing tube 23 is preferably designed as a non-elastic in particular in the radial direction hard plastic tube, achieved according to rotary-dragging of the eccentric 39. The dipping into the tube port 43 vertical tube section 38 rotates with the eccentric 39 in total about the axis of rotation y and more preferably at the same time about the eccentric axis z within the tube connection 43rd

The FIGS. 21 and 22 show a further embodiment with an eccentric formed in accordance with the embodiment 39 described above, to which an at least in the radial direction rigid dispensing tube 23 connects. The dispensing tube 23 is also connected here via a vertical tube section 38 with an exzenterteilseitigen tube connection 43.

The eccentric 39 is not rotatably mounted, but rather taken in this embodiment rotatably in the pumping chamber upper part 7. The vertical tube section 38 can also interact with an eccentrically aligned tube connection 43 formed directly on the dispenser part 9.

According to turning of the gripping portion 16, starting from the, the operation hindering the first position according to FIG. 21 , Be with entrainment of the mouth part 21 in the region of the operating part-side cutout 26 the radial distance between the eccentric axis z and an outer opening plane of the cutout 26 shortened (as in the embodiment described above), which causes a corresponding stiffened design of the tube portion 37 a corresponding emergence of the muzzle part 21 arranged thereon beyond this opening plane addition (see FIG. 22 ).
