Description

  The present invention relates to an aerosol application container.

Provided with a comb in which multiple comb teeth with through-holes are juxtaposed in the vertical direction from the upper front surface of the upper closed communication tube, and the lower end of the communication tube of the comb is fitted to the upper outer surface of the stem standing from the upper surface of the aerosol container There is known an aerosol comb container in which a push button for pressing a comb protrudes from a lower outer surface of the communication cylinder (Patent Document 1).
JP-A-8-20439.

  In the above container, if the communicating cylinder with comb teeth is short, the distance between the comb teeth and the container is shortened so that the container is obstructed when the comb is used, and if the communicating cylinder is long, the communicating cylinder bends when the comb is used. There was a drawback that it was difficult to use.

  In the present invention, the above-described communication tube is provided long to facilitate the use of the comb, and a reinforcing plate for preventing the deflection is raised from a part of the peripheral wall fitted to the outer surface of the upper portion of the container body. The inconvenience of using the long communication tube in this way is not limited to a container with a comb, but the same applies to a case where a brush for removing dirt or an application part for applying a chemical solution is attached to the upper end of the communication tube. Therefore, in addition to the comb-toothed container of the illustrated example as an aerosol type liquid application container, the invention is provided to include a liquid application part attached to the upper part of the communicating cylinder instead of the comb tooth.

As a first means, an aerosol container body with a stem penetrating the top wall and rising upward,
An application member having a liquid application part attached to the upper end of the communication tube;
By fitting the lower end of the communication tube to the upper end portion of the stem and erecting the application member, by pushing down the stem via the push button attached to the communication tube, the liquid in the container flows out through the liquid application portion, In the aerosol-type application container provided so that the liquid outflow can be stopped by the elastic return of the stem by releasing the push button,
From a part of the peripheral wall 22 fitted to the upper outer surface of the container body, the semi-cylindrical plate 23 is slidably fitted to one half outer surface of the communication cylinder 12, and at least of the semi-cylindrical plate. A part of the semi-cylindrical plate has an opening width of a semi-cylindrical plate that is narrower than the inner diameter of the semi-cylindrical plate and the outer diameter of the communicating cylinder, and the push button 13 protrudes from the other outer half of the communicating cylinder. Let
A semi-cylindrical hook 42 is provided projecting from one of the circumferential side surfaces of the semi-cylindrical plate 23 via a hinge 41 so as to slidably cover the other half outer surface of the communicating cylinder. A protrusion 44 for engaging the hook claw 43 on the other side outer surface of the semi-cylindrical plate 23 facing the side surface having the hinge is provided .

  The semi-cylindrical plate portion having the first means as the second means and having the dominant arc surface was formed on the upper portion of the semi-cylindrical plate 23.

As a third means, the semi-cylindrical hook 42 having the first means and the protrusion 44 engaging the hook 43 at the tip of the hook are provided on both sides of the upper part of the semi-cylindrical plate 23 in the circumferential direction. Attached.

According to the first aspect of the present invention, the communication cylinder 12 is fitted into the semi-cylindrical plate 23 so that it can freely slide in the vertical direction within the arcuate surface 31 of the semi-cylindrical plate 23. The use of the application container can be made convenient by preventing the bending. In addition, in the semi-cylindrical portion with the hook, the entire outer periphery of the communication tube 12 is securely held, and the bending of the communication tube 12 can be prevented.

  By making it like Claim 2, the vertical direction length of the semi-cylindrical board part which has the dominant arc surface 31 can be shortened, and a communication cylinder part fitting in this part can be made easy, and the excellent arc surface Since the attached semi-cylindrical part is formed on the upper part of the semi-cylindrical plate 23, the bending of the communicating cylinder during the coating operation can be reduced.

By making it like Claim 3 , since the vertical direction length of the semi-cylindrical board part with a hook is short, and since the communication cylinder by the hook will be carried out in the semi-cylindrical board upper part, it is reliable. It is possible to prevent the communication tube from being bent.

A reference example shown in FIG. 1 and FIG. 2 will be described below. 1 is a known aerosol container body, and the stem 2 is erected by penetrating the central portion of the top wall from above the container body, When the stem is pushed down against the bias, the discharge valve at the lower end of the stem opens so that the liquid in the container can be ejected through the stem.

  The lower end of the communication tube 12 having the application portion 11 at the upper end is fitted in a watertight manner to the outer surface of the upper end portion of the stem, and the stem 2 is pushed down from the lower rear surface of the communication tube via the communication tube. A push button 13 is projected outward. The communication cylinder, the application part, and the push button form the application member 16. In the illustrated example, the application part 11 is formed by a comb part 15 from which a plurality of comb teeth 14 are projected, and the liquid in the container that has entered the communicating cylinder 12 by descending the stem 2 enters the comb part 15 in a known manner. The liquid in the comb portion is provided so as to adhere to the hair by combing the hair.

  21 is an anti-bending member for the communicating cylinder, which can slide in the vertical direction from the upper end part of the peripheral wall 22 fitted to the upper outer surface of the container body 1 to the outer half of the communicating cylinder 12. The semi-cylindrical plate 23 is erected by fitting.

  In the illustrated example, the peripheral wall 22 hangs both the inner and outer cylinders 25 and 26 from the inner and outer peripheral edges of the flange-like top plate 24 to fit the inner cylinder 25 to the outer surface of the container body, and the upper end of the inner cylinder extends upward from the top plate. The rear part (right side in the figure) of the extended cylindrical part 27 provided in this manner is cut open from the upper end to the lower end of the extended cylindrical part 27, and the lower half diameter and upper small diameter half cylindrical part 29 is further raised from the front half part of the extended cylindrical part 27. In addition, the upper portion of the half tube portion is suspended downward to form a lower portion of the half tube portion with inner and outer double walls, and a plurality of ribs 30 are interposed between the double walls, and the half tube The inner wall surface of the semi-cylindrical plate is formed by the upper inner surface of the semi-cylindrical part and the inner wall forming the lower inner surface of the semi-cylindrical part. Further, the inner surface of the front half portion of the extension cylinder portion 27 is reduced in diameter so that the lower end portion of the small diameter portion is a downward stepped portion, and the downward stepped portion is engaged with the upper end portion of the front half portion of the container body 1.

  In the illustrated example, the upper end portion of the semi-cylindrical plate 23 has a major arc surface 31 on its inner surface as shown in FIG. 2, and the width of the opening of the major arc surface is the diameter of the upper inner surface of the semi-cylindrical plate, that is, the communication. By forming the tube 12 shorter than the outer surface diameter of the tube 12 and forcibly pushing it into the arcuate surface 31 from the opening, both ends of the arcuate surface are elastically expanded and the communicating tube 12 is fitted into the arcuate surface. It is possible to combine them. As shown in FIG. 2B, claws 31a and 31a may be attached to both ends of the arcuate surface. 32 is a cap, and the lower end of the peripheral wall is placed on the outward flange at the lower end of the outer cylinder 26.
