Definitions
- Dispenser for dispensing liquid to pasty masses
- the invention relates to a dispenser for dispensing liquid to pasty masses, comprising a pump head and a pump chamber having a pumping chamber having a inlet and an outlet valve, wherein the pumping chamber is formed by a bellows, to which in any case the inlet valve integrally formed further, the intake valve is supported by support arms extending in the circumferential direction of the intake valve, which are connected to the pumping chamber wall and to the intake valve, and the intake valve forms a circumferential, free-cutting circumferential valve lip.
- Donors of the type in question are known.
- the pump chamber designed as a bellows part has a flexible pumping chamber wall.
- This consists in particular of a soft plastic material, further in particular of an elastically resilient plastic material. Integral and possibly the same material hereby the inlet valve is formed.
- a technical problem of the invention is seen in a donor of the type in question, in particular with regard to the function of the intake valve to further improve.
- a possible solution of the problem is given according to a first inventive concept in a dispenser, which is geared to the inlet valve in a (central) longitudinal cross-section of the bellows part circular section, with an upper portion and the lower valve lip, wherein the connection to the support arms at a height center of the inlet sventils or offset from this towards a free edge of the valve lip is formed.
- the longitudinal section extends in the middle of the bellows part, receiving a longitudinal axis of the same, wherein the longitudinal axis in this longitudinal section is a line.
- the dome section extends in particular in the inlet valve closed position in the longitudinal cross-section convex in the direction of the bellows interior or in the direction of the pump chamber interior facing. This leads advantageously in a donor operation in particular via the pressure of the mass in the pumping chamber to a favorable load of the intake valve in the direction of the sealing seat.
- the pressure can act through the dome-like configuration of the inlet sventiles evenly over the circumference of the lower valve lip.
- the valve closure position can thereby be supported in an advantageous manner.
- connection of the support arms may be formed in a center of the inlet valve, wherein the center of the height preferably refers to the entire extension length of the inlet valve, starting from the valve lip to the coupling center, as viewed in the direction of extension of the longitudinal axis of the pumping chamber. Also, this connection can be offset from the center of the height formed in the direction of the free edge of the valve lip, corresponding to a smaller distance to the valve lip than the Kuppelzenit (with respect to the extension length in the direction of the longitudinal axis).
- connection can also be formed in the transition of the upper dome section in the lower valve lip.
- the dome-like configuration of the inlet valve in this case preferably extends alone above the connection region for the support arms.
- the valve lip may be substantially rectilinear with respect to the longitudinal cross-section, and may not increase in accordance with the circular segment-shaped course of the dome section.
- the dome portion may form a semicircle in the longitudinal cross-section together with the valve lip substantially.
- the valve lip can in this case with respect to a longitudinal cross-section substantially tangentially transition into the circular segment course of the dome portion.
- the height of the inlet valve in the longitudinal extent of the pumping chamber (with respect to an inlet valve closure position) between a plane defined by the free end of the lower valve lip and a plane extending parallel thereto, the zenith of the dome section tangent plane can about half the diameter of the inlet s valve in the area of the valve lip, alternatively 0.3 to 0.7 times the diameter.
- the semicircle which may be imaged in the longitudinal cross-section may have rectilinear sections with respect to the contour, for example in the zenith region of the dome section; moreover, as preferred, in the area of the valve lip.
- the Wandungs strength of the dome section may be greater than the wall thickness of the valve lip.
- a wall thickness of the dome portion is preferably provided, which corresponds to 1.2 to 3 times, more preferably about 1.5 to 2 times the wall thickness in the region of the valve lip.
- the wall thickness in the region of the dome section is preferably chosen to be at least approximately constant over the entire extension region.
- the ranges or value ranges or multiple ranges given above and below also include all intermediate values, in particular of 1/10 increments of the respective dimension, if necessary also di- mensionslos.
- the specification of 0.3 to 0.7 times also includes the disclosure of 0.4 to 0.7 times, 0.3 to 0.6 times, 0.4 to 0.6 times, etc.
- the disclosure of 1.2 to 3 times also the disclosure of 1.3 to 3-fold, 1.2 to 2.9-fold, 1.3 to 2.9-fold, etc.
- This disclosure can on the one hand to the limitation serve a specified range limit from below and / or above, alternatively or additionally but for the disclosure of one or more singular values from a respective specified range.
- FIG. 1 shows a dispenser of the type in question in a longitudinal sectional view
- FIG. 2 shows the enlarged area II in FIG. 1;
- Figure 3 shows a Belgteil in cut, perspective view.
- a dispenser 1 essentially consisting of a pump head 2 and a storage container 3, is shown and described.
- the pump head 2 is designed to dispense a liquid to pasty mass 4, which is stored in the container 3.
- the pump head 2 may be formed in a modular manner and inserted from above into the storage container 3.
- the connection between the storage container 3 and the pump head 2 is achieved by means of an adapter part 5.
- the adapter part 5 is essentially cup-shaped with a pointing upwards for receiving the pump head 2 pot opening.
- the pot outer wall of the adapter part 5 is provided with encircling, preferably ring-like protrusions or recesses, for clamping support of the storage container 3, and more preferably for clamping support of a pump head 2 in the non-use position catching cap 6.
- the adapter part 5 is preferably based on a wall shoulder 7 formed on the outside of the circumferential pot wall on the peripheral opening edge of the storage container 3.
- the adapter part 5 further forms a telescope outer part 8 for the linearly displaceable receiving of the correspondingly a telescopic inner part 9 ausformenden pump head. 2
- the pump head 2 is provided with a preferably concentric with a longitudinal center axis x of the dispenser 1 rotating telescopic inner wall 10. This is in the adapter part 5 inside the wall, the telescopic outer wall 11 out forming pot wall out.
- the pump head 2 has a pumping chamber 12 which consists of a flexible bellows part 13.
- the bellows part 13 is in a central longitudinal cross-section as shown in FIG. 1, the longitudinal axis x being in the sectional plane as a line, zigzagging formed running course. In a transverse horizontal section considered this results in an annular configuration of the bellows 13th
- This is preferably a plastic injection-molded part made of a correspondingly flexible, resilient plastic.
- an inlet valve 14 is integrally formed on the foot side. This is in cooperation with a pot bottom side of the adapter part 5 formed valve seat 15th
- the adapter part 5 forms pot bottom side, the bellows part 13 facing, a Stützso- disgust 16 in which a foot portion of the bellows 13 is seated.
- the bellows part 13 is no longer bellows-like or zigzag-shaped in the longitudinal cross-section, but with a solid wall which has a reinforced triangular cross-section in the overlapping area of the support base 16.
- the bellows part 13 sits on the underside of the bottom 19 of the adapter part 5.
- the bottom 19 forms a central opening 20 as a feed channel to the inlet valve 14, which opening 20 is retracted relative to the bottom 19 to the interior of the pumping chamber 12 out.
- the channel runs into two concentric rings 21, 22, of which the outer surface of the ring 21 is designed to sealingly cooperate with a valve lip 23 of the bridge-like inlet valve 14.
- an outlet valve 24 formed of a soft elastic plastic. This seated in a seat part 25, the cooperating with a counterpart member 26 by clamping an upper collar 27 of the bellows 13 and the pump chamber wall supports.
- the counterpart part 26 has a subsection 28 projecting into the fold region of the bellows part 13, which is basically formed like a cylinder. In the subsection 28, the support member 25 is guided.
- the support member 25 forms a channel portion in which the outlet valve 24 is seated.
- the channel section is connected via radially directed passage openings of the support member 25 and the lower portion 28 with the pumping chamber 12 in connection. Facing away from the pumping chamber 12, the channel section of the seat part 25 merges into an output channel 29.
- the bridge-like opening 20 in the bottom 19 spanning inlet valve 14 is connected by means extending in the circumferential direction of the inlet valve 14 Halterungsar- men 30 to the bellows 13.
