Abstract

The invention relates to a dispenser for the metered delivery of small quantities from a liquid container by means of a pressure member. The intention is to simplify such dispensers so that they can be manufactured less expensively and can be filled in a simpler manner than previously. This is achieved according to the invention in that the dispenser consists of only two parts, namely the liquid container and an attachment, the latter being easily removable. In total, the dispenser consists of only six parts, namely the container 1, a transition piece 2, a lid 3 which is also the push button and bears the dispensing pipe, a pump bulb 4 with a valve 5 and a suction pipe 6. Each of these six parts can be manufactured integrally; springs etc., are no longer required. By means of the pump bulb which is preferably made of elastic material, a precisely metered quantity of liquid can be sucked up and delivered in accordance with the size of said pump bulb and the path which the push button can travel. <IMAGE>

Dispenser for liquids

The invention relates to a dispenser for dosed Dispensing of small amounts from a liquid container by means of a pressure device

You have been given the task of “one of those donors To find a particularly simple construction, on the one hand simple manufacture and on the other hand a safe function and dosage guaranteed.

It solves these tasks in principle in that as a pressure organ the lid of the liquid container is used, which can be moved towards the container when pressure is exerted, and that between the container and the lid made of airtight and liquid-tight, flexible material, as Dosing device acting pump (Purapblase) is arranged, in which there is an inlet and outlet valve and the is in communication with a suction tube immersed in the liquid level.

As a result, the invention achieves a concept with which it is possible to assemble such dispensers from only six parts.

set, which for their part can all be produced in one piece and simply put together using snap locks · » This means that «springs and other small parts are no longer required.

Although it is advantageous according to a further feature of the invention, when the pump bladder consists of an elastic material, the object of the invention -will but also solved by non-elastic but flexible material because when the liquid is sucked in, this also takes place a volume increase achieved, although not in the same optimal way

The criterion of the invention, the container as such three main parts, namely the liquid container as such, the intermediate piece and the lid with an outflow opening, to let exist enables an efficient production and assembly of the parts; the suction and dispensing device Apart from the valve, also to be produced in one piece, has a further advantage over the known institutions. Details are in the Claims disclosed, wherein the criterion that the pump bladder itself forms a seal against uncontrolled drainage of the sucked-in liquid, of great importance Meaning is (claim 5)

These features can be taken from the exemplary embodiment of the invention shown schematically in the drawings will.

So are shown in

Fig. 1 shows the entire dispenser in a vertical section with sucked liquid,

FIG. 2 shows a detail from FIG. 1 with the pump bladder compressed and

3 shows the type of filling of the liquid container with the liquid to be dispensed based on the section according to FIG. 1.

The liquid dispenser according to the invention consists of the container 1, an intermediate piece 2, the lid 3, the Pumpblaso k, the valve 5 and the suction tube 6; all parts are manufactured separately from one another in one piece.

The liquid container 1 is in this exemplary embodiment designed as a cylindrical hollow body which has a collar 10 offset inward. About the scope distributed this collar 10 has a Schnapprinf * 11, the with counterparts 21 of the intermediate piece 2 when it is placed together form a snap lock.

The intermediate piece 2 continues the outer contour of the container 1 and has a guide jacket 20 (Fig. 2 and 3) for the lid 3 on. In this guide jacket 20 slots 22 are provided distributed over the circumference of the jacket, in which the barbs 32 of the cover 3 from above can move down (Fig. 1). A downward one

Double collar 23 is used to place and loosen the intermediate piece 2 on the or. from the container 1 f it also has a part 21 of the snap lock. In the center of the top surface 2k of this intermediate piece 2, a receiving trough 25 is provided for the pump bladder k .

The cover 3 », which is at the same time the actuating member for the liquid dispenser, is also designed as a cylindrical casing 30 which is in contact with the casing 20 of the intermediate piece 2 and slides along it when it is actuated. In its center, two pipe sockets 31 and 33 are provided, which protrude downward and are connected to the pump bladder k . The dispensing tube 3k is closed at its free end with a cover 36 which, for manufacturing reasons, is pointed with a film hinge at the outlet. The cover 36 is positively snapped once and then forms the stop of the semicircular outlet. The outflow opening 35 is * provided with a dike-like edge, which is intended to prevent dripping.

The pump bladder k is designed like a ball in its center piece kO. It consists of an elastic material so that it can be compressed by pressing on the cover 3. In the lower part 45 it is adapted in shape to the seat 25 of the intermediate piece 2. The adjoining, downwardly directed hose 41 serves to receive the suction tube 6. 42 and 4 3 denote two hose-like lips of the pump bladder k; they are in contact with the pipe socket 3I, 33 and represent the connection between the intermediate piece 2 and the cover 3. The stop lugs kk prevent the valve ball 5 from being pushed upwards.

The donor works as follows:

The parts, cover 3 with pump bladder h with ball valve 5, suction pipe 6 and intermediate piece 2, are put together, with the snap locks 22, 32 guaranteeing that these parts are firmly connected to one another. The connection can only be released if the tabs 37 carrying the barbs 32 are pressed inward. Then the intermediate piece 2 is placed on the collar 10 of the filled container

If liquid is to be dispensed, pressure is exerted on the cover 3 from above. It is moved downwards, the barbs 32 slide in the slots 22, the pump bladder h is compressed, the ball 5 being pressed onto its seat so that no liquid can flow downwards.

The sealing lip kZ is brought into the position shown in FIG. 2, so that the liquid can flow off via the dispensing tube 3k through the outlet 35. If the cover 3 is released, it moves upwards again, the barbs 32 limiting this movement. Thereby the pressure on the lip k2 stops , it is applied again at 33 and seals the inside from the outside. A vacuum can thus arise in the Purap bubble k , which presses the ball 5 against the stop lugs kh , so that liquid is sucked in. The upward displacement is limited by the barbs 32.

The dispenser according to the invention is suitable for all types of liquids, as long as they are not too viscous ₃ ind; it is preferably used as a soap dispenser.
