Description

[Detailed description of the invention] For semi-liquid, viscous or pasty substances dispenser head field of invention The present invention relates to a dispenser head for semi-liquid, viscous or pasty substances. Can be mounted on containers filled with substances of this type or on valves. is fixed to the closing member of the valve and externally inserted through the hole in the dispenser. It is equipped with a duct that leads laterally to the section. In addition, the dispenser head of the present invention It operates by compressing a valve spring.

Conventional technology This type of dispenser Helad has been used for many years to dispense liquid substances using an aerosol method. It has been used to After that, semi-liquid, viscous products such as edible or cosmetic creams are used. It has also been used to separate paste-like substances. But when the valve closes It is impossible to prevent a certain amount of material from remaining in the duct of the dispenser head after chaining It is. The residual material in the duct of this dispenser head is removed from the preparative hole onto the head. The purpose of the present invention is to solve the above-mentioned drawbacks, namely, to prevent the contents of the container from leaking after use. The purpose is to eliminate spills and drips.

Summary of the invention For the above purpose, a dispenser head according to the invention is provided which can be slid longitudinally on said head. a cap that is attached to the head and has a notch facing the aliquoting hole; The force is weaker than that of the valve spring, which is continuously compressed between the cap and the valve spring. a spring, which is secured to the cap and closes the aliquot hole in the rest position; A flexible blade that separates and moves from the separation hole by applying pressure on the cap. It is characterized by consisting of the following.

When the pressure applied on the valve is relieved, the valve closes and then the flexible valve A radar closes the sorting hole and is thereby housed within the sorting duct in the head. This prevents the substances contained in the liquid from flowing out from the separation hole. When the substance in the container is not used When the separation hole is closed, the material contained in the separation duct in the head is removed from the outside. left in isolation. In other words, the contamination of the substances contained in the duct by foreign cars is prevented. It can be prevented. Therefore, continuous use of the substance near the dispersion pores is possible. This thing is This is not necessarily guaranteed with known dispenser heads.

The flexible blade may be integrally molded with the synthetic cap, and It may be made of other metal material or the like and attached to the cap.

However, the blade supports the separation hole under tension to effectively close it. It is preferable to

Description of the preferred embodiment A head 1 made of synthetic material is fixed to a valve closing member 3 installed in a cylindrical valve body 4. carrying a defined longitudinal rod 2, the valve body 4 also made of synthetic material and with its valve seat has a backing 5 of compressible synthetic material. The valve 3 is biased by a spring 6. It is energized by the locking 5. The valve body 4 is represented here schematically.

The valve body 4 is fixed in a known manner over the bore of the container by means of a metal cup. It may be of any of a variety of known shapes. The base of the valve body 4 is connected to the container. Has a lower. The head 1 has a horizontal aliquot port 8 shaped like a duck's beak, and a It passes through the horizontal sampling port to the head 1 and extends laterally at the height of the valve backing 5. A slightly conical preparative duct communicating with a preparative duct 10 having an outlet arranged 9.

A cylindrical cap 11 made of synthetic material is attached to the upper periphery of the head. child The cap is compressed between the head and the cap and the valve spring 6 is compressed between the head and the cap. is held away from said head 1 by a spring 12 having a force substantially less than ing. The cap 11 has a rectangular transverse cutout 13 for the aliquot port 8 .

Beneath the port 8, the head is substantially parallel to the flat inclined bottom portion 15 of the port 8. It has an inclined support surface part 14. The end of the support surface portion 14 supports the elastic steel blade 17. It has a flange 16 that holds it. This blade 17 is inserted into the groove 18 in the cap 11. It is fixed by clipping. This bend is the blade This is possible due to the flexibility of the folded edge 19 of the base. of the flexible blade 17 The free end is bent at 20 to press the end of the aliquot port 8 under tension and perform the aliquoting process. It closes the mouth orifices. The tip of the folded white part 20 is folded back and is exposed to the action of the flap 12. The support surface portion 22 (Fig. 4) on the aliquot port 8 can be biased by .

The operation of the above head will be explained with reference to FIGS. 4 and 5.

When pressure is applied to the cap 11, the area indicated by the arrow in FIG. 4 is first compressed.

This causes the cap 11 to move relative to the head 1. The flexible blade 17 is involved in the movement of the cap 11. For this purpose, the bending portion 20 of the blade is separated. Move away from the end of the inlet 8 to release the aliquot hole. The whitening part 20 of the blade is under tension. , the end portion supports the inclined bottom surface portion 15 of the aliquot port 8 .

If pressure is continued to be applied to the cap 11, the cap 11 will close to the edge 2 of the transverse cutout. 3 carries the head 1 so that the valve spring 6 is compressed and the upper The valve closing member 3 is separated from the backing 5, whereby the material to be separated is released. It flows out through the duct 10 and the duct 9 in the preparative port 8.

When the pressure on the cap 11 is released, it becomes substantially stronger than the spring 12. The valve spring 6 which is present first closes the valve and then returns to the state of FIG. 4 again.

When the pressure on the cap 11 is completely relaxed, the spring 12 will release the cap with respect to the head 1. The end portion 21 of the flexible blade 17 is raised by the flange 16. Through the applied thrust, the inclined inner surface 15 of the port 8 and the rounded end of the inner surface It slides on the part while curving, and then slides onto the sorting hole of the sorting port 8 as shown in Figure 1. The aperture hole is then closed.

The present invention is not limited to the embodiments described above, and various structural changes are possible. Special For example, a blade 17 having stronger flexibility is used for the support surface portion 14. It can be omitted if it is done. This blade is located inside the cap 11. The end portion of the inclined portion may be buried and simply fixed.

The above flexible blade is not made of metal, but is made of synthetic material, glass fiber, garbon, etc. It may be made of material.

The flexible blade may be integrally molded with the cap 11. In other words, The supporting surface portion 14 constitutes a flexible blade, and for that purpose the aliquoting port 8 is It may have a vertically folded end that can close the hole.

The hole of the preparative port 8 is precisely formed or has a backing. In some cases, the sorting hole can be closed almost completely leak-tight.

The dispenser head does not necessarily have a dispensing port protruding from the cap. There is no need to If the head does not have a sorting port of this type, the above is possible. A flexible closure blade is mounted inside the cap and between the cap and the head. It's okay to be kicked.
