Description

1 64503

The present invention relates to a fluid dispensing container, preferably made of a flexible or wooden material, such as a plastic container with a dispensing spout at one end, possibly with a closure member, for dispensing by pushing the front surface of the container inwards, and the container is attachable to the base with the dosing spout facing down.

The invention thus relates to a fluid dosing container from which dosing takes place by a well-known "pumping": the front wall is pressed inwards, whereby the wall, due to its flexibility, returns after the end of the pressing.

15 With the dosing tank attached with the dosing spout facing down, the substance to be dispensed remains in the tank. When pumping, liquid is drained, but when pumping is complete, the liquid stops draining. The corresponding air space must then enter the tank so that the vacuum does not increase in the tank.

The access of air through the mouth and possibly the closing member to the container is crucial in connection with the container according to the invention, because otherwise the container will flatten. The tank does not leak because there is a small vacuum at the top. In addition, at the end of the dosing, air bubbles form an air mattress 25 which prevents the flow of liquid 25 into the mouth opening or immediately above the closing member or at both said points.

German patent publication DE 2 024 294 discloses a washing liquid dosing container with a threaded mouth opening at one end and a nozzle with 2 64503 openings and a closing pin inside. Around the mouth there is a screw cap with outlet holes, which can be turned to close and open the nozzle. This container is intended to be kept on a horizontal base 5, in places similar to ordinary soap. When dispensing the washing liquid, hold the tank in hand, turn the cap to the open position and push the front wall of the tank inwards to dispense the liquid.

Finnish patent publication 23 699 discloses a closure member for compressible tubes containing liquids or pastes, comprising an expanded curved portion with a slit-like extrusion opening of rubber or similar resilient material and an associated cylindrical portion. However, the known closure member 15 does not allow replacement air into the tank, so it can only be used in conventional compressible metal tubes. It is not suitable for containers made of a flexible material such as plastic.

U.S. Patent No. 4,133,457 discloses a liquid dispensing container 20 provided with a plate-like closure member. This closure plate has slit-like cuts in the central portion from which the liquid is dispensed, as well as at least one small hole intended to increase the flexibility of the closure plate and to allow replacement air into the container 25 to prevent the container from flattening. This dosing container is thus not sealed and cannot be used fixed in a vertical plane, with the dosing spout facing downwards. The shut-off plate mainly prevents the liquid from flowing rapidly out of the tank, for example when it falls over.

The container according to the invention is characterized in that the dosing nozzle consists of two or more truncated cones extending from each other and can be cut at predetermined points determined by the viscosity of the liquid to be dispensed and the elasticity of the compressible container. Between the an-lifting nozzle and the container there may possibly be a closing member through which one or more channels pass during the flow.

The dosing container according to the invention is simpler and more hygienic in use than the known dosing containers. When mounted on a wall and with the mouthpiece open, the only action is to "pump" the substance out of the container. For example, if the hands are more or less dirty, the washing liquid can be pushed inwards from the wall of the container with the palm of the hand, if necessary, so handling is more hygienic than taking the container completely for pumping, possibly by turning the cap. Furthermore, due to its simpler structure, the dosing container according to the invention is easier and thus cheaper to manufacture.

As dispersing fluids, substances with a viscosity ranging from liquid to ointment can be used. Examples are washing liquid, hand cream, shampoo, hair conditioner (hair conditioner), shaving foam, various skin care milks, etc. Of interest are so-called thixotropic substances which have a high viscosity at rest but which, when pumped from a container according to the invention, , are nes-25 roads.

Containers containing different dispensers, such as detergents, hand cream, shampoo, etc., can be attached side by side above the sink, whereby the different containers can be simply separated by making the containers different colors.

The invention will now be described in more detail with reference to the drawing.

Figure 4 shows a cross-section of the closure member of the dosing container.

Figure 5 shows a detail of the location of the closure member in the dispensing container.

Figure 6 shows the closing member.

Figure 7 shows a closure plate.

The container 1 can be made, for example, of flexible plastic, such as polyethylene or polyvinyl chloride. The rear surface of the container has a fastening surface with an adhesive, such as a sticker surface 2, by means of which the container can be fastened to its base downwards of the dispensing spout 3. The tank is intended to be fixed to the wall, for example above the sink.

The dispensing spout 3 preferably comprises a nut part and a conical nozzle part which can be cut at certain points 4. The cutting points are determined as a function of the viscosity of the liquid to be dispensed and the elasticity of the compressible container. The mouth of the dispensing spout is closed by a bundle 5 or other similar member formed during the manufacture of the container.

With the tank mounted upside down, i.e. when the open dosing spout 3 is reached downwards, the substance to be dispensed remains in the container due to the vacuum at the top. Studies have shown that water with a viscosity of 1 centipoise at 20 ° C remains in a container with a mouthpiece orifice diameter of 1 mm. When pumping, water is removed, but when the pumping head 30 stops, the water stops draining. When pumping the substance out of the tank, a corresponding volume of air must enter the tank so that the vacuum does not increase in the tank. The passage of air through the mouth into the container is of crucial importance in connection with the container according to the invention, which has a downwardly directed dispensing spout open at its end.

In addition, the entry of air through the mouth into the tank is important in that at the end of the pumping the nozzle of the tank 5 becomes a couple more liquid droplets, which are replaced by air bubbles which form a flow barrier to the liquid in the tank. If the container has a closing member 6 between the dosing nozzle and the container, the few air bubbles 10 entering the container after pumping form a flow barrier immediately above the closing member, and at the same time a flow barrier is formed in the tank nozzle.

The diameter of the mouth of the dispensing spout can be in a wide range, for example 0.1 to 6.0 mm. As the diameter of the orifice increases, the viscosity and / or surface tension of the agent to be dispensed is increased. As mentioned above, water having a viscosity of 1 remains in a container with an orifice diameter of 1 mm. Thus, an orifice with a diameter of 1 mm is also suitable for real liquids, but it is also useful for creams, for example. Thus, for practical reasons, 1 mm can be chosen as the diameter of the mouth opening for all fluids which are dispensed by the container according to the invention.

25 The length of the dosing nozzle may vary; it may be, for example, 2-4 cm, preferably 3 cm. The number of cut-off points on the dosing spout can also vary. For example, a 2 to 3 cm long dispensing spout may have 2 to 4 cut-off points located at points where the si-30 has an electrical diameter of about 1.10 and 0.70 mm or about 1.25, 1.00 and 0.75 mm, or about 2.40, 2.00, 1.50 and 1.00 mm.

The possible closing member 6 is located between the dispensing spout and the container. The closure member consists of a sleeve, 6 64503 with a reticulated open-porous or perforated channel area 7. It is made of a rather rigid material, such as plastic or metal. Area 7 is a reticulated or perforated area or a coarse-fiber-supported felt or mesh layer.

The closure member is preferably a sleeve made of plastic, the channel area of which is perforated and in which the total area of the holes is about 10 to 20% of the area of the channel area. The coarse fiber layer is, for example, me-10 stable wool.

The length of the channels in the channel area is 0.5 to 1.3 mm, preferably 1.0 mm.

The closure member may also consist of two parts, in which case, in addition to the closure member 6, it has a separate, preferably circular, closure plate 8. In this case, the closure member consists of a sleeve made of rigid material perforated area or coarse fiber felt or mesh layer.

20 The barrier plate is a plate made of a flexible material, preferably rubber, or a plate made of a rather rigid material, such as plastic or metal.

The channel area 9 of the rigid plate is a mesh or perforated area or a coarse-fiber felt or mesh layer, preferably having a thickness of 0.6 to 1.4 mm.

The channel area of the flexible plate is formed by an incised area 9a with a plurality of parallel incisions, preferably 5 to 7 parallel incisions, and one incision perpendicular to them, which is preferably in the middle of the plate.

The flexible closure plate according to the invention opens easily when the container is compressed and allows replacement air 7 64503 to enter the container after the compression has ended, after which it closes very tightly. Due to the shape of the cam, even a thick paste does not dry quickly, but the serviceability of the dosing container according to the invention is maintained despite long storage.

The flexible barrier plate is made of rubber, preferably soft natural rubber, or other elastic material having a bundle between 35 and 75%, preferably about 62% (SIS 162 215) and a hardness of 20 to 60, preferably about 40, dimensions IHR- device. The material is preferably chemically resistant. The thickness of the plate is preferably 0.5 to 1.3 mm.

The total cross-sectional area of one or more flow channels 15 passing through the channel area 7 of the closing member 6 and the channel area 9 of the possible closing plate 8 is large during flow, preferably about 10-30% of the area of the channel area 7 and / or 9.

The diameter of the closure member and the orifice is selected according to the substance to be administered.

The following examples illustrate the invention:

Example 1

A dispensing container with a closure member mounted downwards of the dispensing spout is filled with liquid soap. The perforated channel area 25 of the closure member has a diameter of 11.5 mm and has 97 holes, each having a diameter of about 0.4 mm and an inner diameter of the dispensing spout at the outlet opening of 2 mm. The container is easy to use and does not leak after use when dispensing aqueous surfactant solutions with a viscosity of 500 cP.

Example 2

The metering tank mounted downwards of the dispensing spout without a closure member is filled with a lotion-type hand cream which is somewhat fixedotropic and has a viscosity of about 30,000 cP.
