Description

Dispenser for dispensing liquid to pasty masses

The invention relates to a dispenser for dispensing liquid to pasty masses, with a dispensing opening, a storage space for the mass and a pumping chamber with an inlet and an outlet valve, wherein for carrying out a pumping movement, an upper and a lower part of the pumping chamber are movable relative to each other and through Turning of an actuating part for carrying out a pumping movement can be acted upon on the pumping chamber, wherein further the pumping chamber has a different outlet opening from the discharge opening.

Such a dispenser is known for example from EP 1 674 162 Bl. In the case of the known dispenser, with the movement of the pumping chamber, at least the upper part of the pumping chamber at the same time, the outlet opening, which is arranged in the direction of the pumping direction and which follows in the direction of flow of the pumping chamber, is moved. Such a trained donor is not always considered advantageous.

FR-Al-2380076 discloses a dispenser in which the mass in the pumping chamber is precompressed by a threaded sleeve and then dispensed by a push-action displacement of the outlet. The line connection between the discharge opening and the outlet opening is rigid, as this also the pumping movement is transmitted. This is despite a spring arrangement received in this rigid line connection and of a dispensing head having the dispensing opening.

The prior art is also referred to the DE-Ul -20-2004019763. This known dispenser also has a dispensing opening which moves vertically in the dispensing head during a pumping operation. Next is here too between the discharge opening and the outlet opening of the pumping chamber only given a rigid line connection.

DE-Ul-29920931 relates to a dispenser, but which has no pumping chamber for dispensing a liquid to pasty mass, but only for the compression of air. Also in this article, the dispensing opening is movable relative to the dispenser and is given a rigid conduit connection between the dispensing opening and the dispensing opening. Based on the above-described prior art, the invention has the object to provide a dispenser for dispensing liquid to pasty masses, in which the mass output can be achieved by a rotary movement of an operating part, but at the same time a favorable use is possible.

According to a first teaching of the invention, a dispenser for dispensing liquid to pasty masses is provided, in which is based on the fact that the dispensing opening is fixed to the dispenser and that to compensate for the pumping movement between the dispensing opening and the outlet opening a length-compensating line connection is formed. The movement of the pumping chamber is maintained in the previously known sense. At least one upper and / or lower part of the pumping chamber, for performing a pumping movement. However, this pumping movement is not recognizable to a user. In particular, not at the movement of the discharge opening. The discharge opening is fixed. However, a length-compensating line connection is provided inside the part having the discharge opening. The relative to the dispenser - in pumping direction - fixed discharge opening is also conducive to use. The user does not have to follow a movement of the dispensing opening when dispensing the mass. Further features of the invention are described below, also in the figure description and the drawing, often in their preferred association with the concept already explained or illustrated, but they can also be independent or in another overall context meaning.

Thus, it is preferred that a length compensation is achieved by a telescoping interaction between two line parts. For this purpose, for example, starting from the dispensing opening, in the direction of the pumping chamber, a first line part can be formed, which is then fixed correspondingly to the dispensing opening. At the outlet opening of the pumping chamber may be followed by a second conduit part which moves together with the pumping chamber or an upper part of the pumping chamber or acting on an upper part of the pumping chamber part. These two pipe parts may be in a position of the upper part of the pumping chamber, etc., which is closest to the discharge port, in a maximum overlap and in a position in which the upper part of the pumping chamber, etc. furthest from the discharge port is removed, be in the slightest overlap. One of the conduit parts may form an outer conduit part and the other conduit part an inner conduit part.

In another, optionally alternative embodiment, it is provided that a length compensation is achieved by a bellows-shaped line section. In the same way as also the pumping chamber, as described below, is preferably bellows-shaped with circumferentially extending inlets and outlets, arranged one above the other in the pumping direction or a flow direction of the mass, the line section can also be arranged in the circumferential direction be provided to the mass flow extending inputs and Ausfaltungen that allow in accordance with the length compensation in the same way. In particular, this requires no additional Seal. The line section is formed closed despite Längenveränderbarkeit continuous.

The pumping chamber is preferably acted upon by the pumping movement to be acted upon by a loading part which is rotatable with the actuating part. The pumping chamber itself can be designed as a separate component, but with at least one upper part being movable relative to a lower part. The mobility can also be provided by a pump piston guided in the pumping chamber, which represents an upper part of the pumping chamber in this respect.

The loading member is a preferably further separate part, which acts on the one hand on said upper part of the pumping chamber and on the other hand is rotatably connected to the actuating part.

The loading part is accordingly preferably movable relative to the actuating part in a pumping direction. The loading part can be arranged to be arranged in the line section and the pumping chamber.

The actuating part may further preferably have the dispensing opening at the same time. For this purpose, it may, for example, in cross-section, its outer surface in any case relating, be formed substantially U-shaped. Wherein the U-web runs transversely to a pumping direction, and preferably horizontally directed at usual use. It can form an upper stripping surface of the dispenser, in which then at the same time preferably the dispensing opening is arranged.

The actuating part is more preferably only to move in rotation. It can intervene on a further fixed part of the dispenser with a locking projection in a rotary groove. By means of the locking projection at the same time a favorable installation of the moving part on the other dispenser part is possible. Instead of the locking projection can also be a Umbiegevorsprung or other Eingreifvorsprung that can not be brought by latching movement in connection with the rotary, be provided.

The actuating part is also preferably designed for entrainment of the loading part. It has for this purpose a suitable Mitschleppvorsprung, which can act for example on one or more radially projecting arms of the biasing member. Appropriately, a slot guide can be provided on the actuating part for this purpose, in which said arms or other parts of the actuating part can move in any case vertically or in the pumping direction.

The actuating part is preferably further guided in a rotationally fixed guide part. For this purpose, a loading arm, or another part of the actuating part, which on the one hand is entrained by the loading part, on the other hand cooperating with the guide part by passing through the loading part, may be provided. For this purpose, the slide part can have a setting that predetermines the pumping movement of the actuating part.

The pumping chamber itself can preferably be designed as a pumping bellows. This allows a rational, practically one-part design of the pumping chamber.

While a bellows bottom can be connected in a snap fit manner, clamped or otherwise connected to a corresponding bottom part of the dispenser, which is preferably stationary, an upper, dispensing opening side part of the bellows can have the outlet opening and can be pumped by being acted upon by the loading part be movable. The bellows may preferably act in the sense of a return spring. A firm connection between the loading part and the upper part of the pumping chamber or the bellows is not required. However, it can also be provided, for example, to bring about the rotational movement and the provision of the upper part of the pumping chamber. In the bottom region of the pumping chamber or of the bellows, an inlet valve of the pumping chamber can be formed. Associated with the outlet opening, a dispensing valve may be provided. Both valves may be formed, for example, as check valves.

However, it is also possible a pumping chamber, which has only one constructive actually existing valve. The further valve can be formed, for example, by a suitable (thin) formation of the line connection from the outlet opening to the dispensing opening. If a sufficiently high flow resistance is given here, also as a function of the viscosity of the mass to be dispensed, this can also lead to the effect of a second valve, which is basically necessary for carrying out a pumping movement, being achieved.

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

Fig. 7 is a plan view of the dispenser in use; and

Fig. 8 is a side view of the dispenser in use. Shown and described is a dispenser 1, with the liquid to pasty

Masses can be issued. For example, creams or lotions. The dispenser can also be designed for spraying, for example for spraying or pumping out perfumes, perfumes or water. The dispenser 1 has a storage space 2, in which in the embodiment of FIG. 1 a dip tube 3 is inserted, which via a suction opening 4 by means of a pumping movement of the pumping chamber 5, a suction of mass from the storage space 2 and the final transport to a discharge opening 17th allows the donor.

The pumping chamber 5 has only schematically indicated valves, an inlet valve 6 and an outlet valve 7.

To carry out a pumping movement, the pumping chamber formed here by a pumping bellows 8 is compressed and moved apart again. Specifically, in the exemplary embodiment, by means of a loading part 9, which is preferably formed as a rigid part, for example, of a hard plastic. The dispensing opening 17 is designed to be stationary in the dispenser 1 described. This means that it is not movable in the vertical direction or in the direction of a pumping movement, see arrow P. However, it can, as explained below, since it is formed by an actuating member 10 itself, rotate with this actuating part. At least one edge of a relevant opening in the actuating part 10 forming the dispensing opening 5.

The dispensing opening 17, or a line section before or immediately before the dispensing opening 17, can also be designed as a self-closing valve, a conventional valve (eg non-return flap), a spray insert or an opening area not further provided with means beyond.

To compensate for the pumping movement, which means a vertical movement of the loading part 9 with regard to the illustration according to FIG. 1, a line connection 11 is provided between an outlet opening 12 of the pumping chamber 5 and the dispensing opening 17 through a length-compensating line connection 11.

The length compensation is achieved here by the fact that the line connection 11 similar to the pumping bellows 8 is given by transversely to the pumping movement P, or extending in the horizontal direction folds and protuberances that can be moved together according to bellows and apart can be driven.

As can be seen in further detail from FIG. 2, the urging part 9 furthermore has two entrainment arms 13 formed opposite one another in the exemplary embodiment. A driving arm 13 is initially received in a longitudinal opening 14 of the actuating part 10. The longitudinal opening 14 is preferably adapted to a driving arm 13 such that the driving arm 13 can move here practically only in the longitudinal direction of the longitudinal opening 14. As indicated by dashed lines in Figure 3, the longitudinal opening 14 may be formed downwardly open in the actuating member 10.

The actuating part 10 is shown below in cross section, at least for the formation of the outer surface, formed substantially U-shaped. A U-web 15 in this case forms an outer stripping surface or upper stripping surface 16 as the end face of the dispenser. In this area, the dispensing opening 17 is then also apparent. The stripping surface 16 may be designed differently in detail. For example, also concave or convex.

The U-legs form the outer area of the dispenser to be attacked by a user in a conventional manner for rotational movement, which also extends in the vertical direction in the exemplary embodiment in the direction of the pumping movement P or in the case of a normal placement of the dispenser approximately according to FIG. But it can also be provided, for example, a conical extension.

The actuating part 10 further has a driving sleeve 18, which is formed by, in the embodiment and preferably, concentric with the said U-webs with a smaller diameter inside running tubular area. The driving sleeve 18 is on the inside of the U-web. In the driving sleeve 18, said longitudinal opening 14 is formed.

The biasing member 9 is also formed substantially U-shaped, wherein the U-web is arranged on the underside with respect to the representation.

By the biasing member 9 extends, preferably centrally, a ground-passing portion 19, on the one hand provides a connection to the pumping chamber, preferably at the outlet opening 12 and on the other hand, a connection to the line section 11. The line section 11 could also be directly connected or attaching to the Outlet opening 12 may be formed. The biasing member 9 is preferably only vertically movable, while the actuating member 10 is practically only rotationally operable. The line section 11 is in its end regions in each case permanently connected to the actuating part 10, but preferably releasably connected to the loading part 9 and / or the outlet opening 12.

The ground-passing portion 19 is also formed as an inner sleeve part, such as the driving portion 18 of the operating part.

At the U-legs seen in cross section, the driving arms 13, which are formed directly on a plastic part in the exemplary embodiment, are formed on the outside and transversely to the pumping movement P.

Next, a link member 20 is provided, on the one hand has a sleeve 21 in which inside a link 22 is formed. In this gate 22, the driving arms 13 engage and are rotated by rotational drive by means of the actuating member 10 is rotated relative to the fixed gate member 20 so that the predetermined by the gate 22 up and down movement results.

In the exemplary embodiment and preferred, the slide member 20 is at the same time of the same material, one-piece, formed with a lid portion 23 which closes the storage space 2 upwards. The cover portion 23 and thus in the exemplary embodiment, the sliding member 20 is latchably connected to a dispenser base 24, which forms the storage space 2.

In the embodiment of Figures 1 and 2, the link 22 is seen to be provided such that over a circumference of 360 degrees two low points 25 and two high points 26 result. In the embodiment of FIG. 5, eight high points 26 and correspondingly eight low points 25 are evidently formed over the circumference. In the course of a 360 degree rotation of the actuating member 10 relative to the fixed dispenser base 24 results in the embodiment of Figures 1 to 4 can be seen a dual output of mass, in the embodiment of Figure 5, however, an eightfold output of mass.

In the embodiment of Figure 4, the lid portion 23, which is also formed here preferably in one piece with the slide member 20, deviating from the lid member 23 of the embodiment of Figures 1 to 3 is formed. To achieve a more compact design of the dispenser 1, the lid portion 23 has a draw-in portion 27, with which he, starting from an upper edge 28 of the dispenser bottom 24 on which he sits, initially extends down to then comparable to the embodiment of Figures 1 to 3 in a horizontally extending section to pass. At this horizontally extending portion is then visible the sleeve 21, which on the inside forms the slot 22, integrally formed. In the embodiment of Figure 4, a follower piston 29 is shown in the storage space 2 on the underside. By sucking by means of the pumping chamber, the mass is reduced in the storage space and the follower piston 29 thus tightened. In the reservoir, instead of about the follower piston, also a bag to be sucked out can be arranged. In addition, instead of the bag a bellows part, as it is basically described here in terms of pumping chamber. For all embodiments, it is preferred that after assembly no relative movement between the parts 23 and 24 is possible. This by an already mentioned bouncing connection and / or a screw connection. With reference to Figures 7 and 8, it can be seen how suitably the dispenser is to be handled by a user. With one hand he can hold the lower part, while with the other hand, the upper is rotated relative to it.
