Description

[Detailed description of the invention] The present invention relates to an improvement of a coating nozzle protection device for preventing coating nozzles for applying adhesives or paints from clogging when not in use. A sponge 3 impregnated with a curing liquid 2 such as a solvent is placed at the bottom of a cap 1 having a cylindrical bottom shape, and a coating nozzle 4 for applying a coating material such as adhesive or paint is placed inside the cap 1. This relates to a protection structure for a certain coating nozzle, in which a cap 1 is inserted and fitted onto the coating nozzle 4 in a detachable manner.

Conventional coating nozzles for applying coating materials such as adhesives and paints will become clogged with the coating material at the tip of the coating nozzle after 5 to 10 minutes of use, so it is necessary to remove the fixed coating material each time before use. However, it had the disadvantage of poor workability.

The present invention solves the above-mentioned drawbacks, and its purpose is to removably attach the coating nozzle to a cap containing a sponge impregnated with a curing liquid at the bottom, so that the coating can be easily applied when not in use. Since the nozzle can be kept moist with the curing solution, the coating material at the tip of the coating nozzle will not stick, and the coating nozzle can always be kept in a usable condition, so there is no need to remove stuck coating materials. To provide a coating nozzle protection structure that is unnecessary and can improve workability.

The present invention will be explained in detail below with reference to illustrated embodiments.

The rubber cap 1 has a substantially cylindrical shape with a bottom, and an uneven strip 6 is provided along the entire circumference on the upper edge of the inner periphery to improve the adhesion with the fitting protrusion 5 of the coating nozzle 4. , a plurality of sponges 3 impregnated with a curing solution 2 are provided at the bottom of the cap 1.
are stored, and each sponge 3 is located below the surface of the curing liquid 2.

As the curing liquid 2 to be impregnated into the sponge 3, toluene, benzene, acrylic, vinyl acetate, urethane, and vinyl chloride liquids, thinners, etc. can be used.
In short, the curing liquid 2 may be any liquid material with a low boiling point that can act as a solvent for applied materials such as adhesives and paints and prevent solidification of the applied materials.

The coating nozzle 4 is for applying a coating material such as adhesive or paint, and a fitting protrusion 5 having an outer diameter approximately the same as the inner diameter of the cap 1 protrudes in an annular shape on the lower end surface of the coating nozzle 4. A nozzle part 7 projects downward from inside the fitting projection 5.

Then, a coating material such as adhesive or paint is applied to the object to be coated using the coating nozzle 4, and immediately after the continuous coating operation is finished, the uneven strip 6 is brought into close contact with the fitting protrusion 5 so that the cap 1 The distal end portion of the cap 1 is inserted into the fitting protrusion 5, and the cap 1 is detachably attached to the nozzle portion 7 of the coating nozzle 4.

The coating nozzle 4 is filled with a fluid coating material, and if the nozzle part 7 is left exposed, the solvent will evaporate and the coating material at the tip of the nozzle part 7 will solidify in 5 to 10 minutes. However, since the nozzle part 7 is covered with the cap 1, the solvent of the coating material is difficult to evaporate, and the curing liquid 2 in the cap 1 evaporates to keep the nozzle part 7 in a moist state, so that the application of the nozzle part 7 is difficult. Things become more difficult to solidify, and can be prevented from solidifying for more than a month, for example.

On the other hand, when reusing the coating nozzle 4, the coating operation can be performed immediately by simply removing the cap 1 without cleaning the nozzle section 7.

In addition, if the nozzle part 7 is covered with the cap 1 so that the tip of the nozzle part 7 is located between the sponges 3, the nozzle part 7
The effect of preventing solidification of the tip can be further improved.

As described above, this invention allows the application nozzle to be kept moist with the curing liquid when not in use by removably covering the application nozzle with a cap containing a sponge impregnated with a curing liquid at the bottom. The coated material at the tip of the coating nozzle does not stick, and the coating nozzle can be kept in a usable state at all times, eliminating the need to remove stuck coating material and improving work efficiency. It is possible.
