[Prior art]
For example, as disclosed in JP-A-2001-46144, a container body that erects the mouth and neck through the shoulder, an iron tube member that is fitted to the inner surface of the mouth and neck and hangs down into the container body, and an outer surface of the mouth and neck 2. Description of the Related Art A container with an application bar is known which includes an application member that hangs an application bar from the inside of a cap screwed into the container.
[0003]
[Problems to be solved by the invention]
Since the squeezing cylinder member is attached with a squeezing cylinder for removing excess liquid adhering to the application rod, if the squeezing cylinder member is not securely installed in the container body neck, When the application member is extracted, the ironing cylinder member may come out together with the application bar.
[0004]
In order to eliminate such defects, an outward flange attached to the upper end of the iron tube member is engaged with the upper end surface of the mouth neck portion, and a large outer diameter portion larger than the inner diameter of the mouth neck portion is formed at the lower portion of the iron tube member. It is provided that the upper surface of the large outer diameter portion is engaged with the downward stepped portion formed by the lower end of the mouth-and-neck portion. In this way, the ironing cylinder portion is formed of a rubber-like elastic material. Therefore, the strength of the large outer diameter portion gradually decreases, and therefore, the application member may be extracted together with the application rod in the same manner as described above.
[0005]
The present invention eliminates such drawbacks.

[0009]
An iron cylinder member is fitted into the upper part of the container body. The ironing cylinder member will be described later.
[0010]
Reference numeral 11 denotes an application member, which is formed of a cap and an application rod suspended from the inside of the cap.
[0011]
The cap 12 has a lower part of the peripheral wall 13 suspended from the outer periphery of the top wall screwed into the outer surface of the mouth neck 3, and an application bar 14 is suspended from the upper part of the peripheral wall, and the lower part of the application bar is formed as a coating part 15 formed by a brush. Yes. In addition, a taper-shaped protrusion 16 having a small diameter at the bottom and a large diameter at the top is attached to the top of the application bar. The lower end of the protrusion is preferably a small outer diameter portion 17.
[0012]
The iron cylinder member 21 described above is formed of an elastic material such as rubber or elastomer, and an outward flange 23 is attached to the upper end of the cylinder 22, and the outward flange is engaged with the upper end surface of the container body neck. Fit to the inner surface of the neck, and the tube portion except the outward flange and the lower part is tightly fitted to the inner surface of the mouth and neck portion 3, and the outer diameter of the outer diameter is larger than the inner diameter of the mouth and neck at the bottom of the tube An inward flange-like throttle cylinder 25 is provided, which is provided with a portion 24 so that the upper surface of the large outer diameter portion is engaged with or close to the lower end surface of the neck and neck portion, and is inclined obliquely inwardly on the inner surface of the intermediate portion of the cylinder 22. ing.
[0013]
As shown in FIG. 2, when the cap peripheral wall is screwed onto the outer surface of the mouth and neck portion and tightened, the throttle cylinder 25 is brought into contact with the upper surface of the throttle cylinder 25 so that the outer surface of the tapered protrusion 16 is in a watertight manner. In addition, the inner diameter of the lower end of the throttle tube is substantially equal to the outer diameter of the coating rod 14 and is smaller than the outer diameter of the coating portion 15.
[0014]
The large outer diameter portion 24 has an inner surface as a large inner diameter portion 26, and a downward stepped portion 27 and an upward stepped portion 28 are continuously arranged above and below the large inner diameter portion. An elastic ring 29 made of synthetic resin or the like as shown in FIG. The ring shown in FIG. 3A has a short cylindrical shape, FIG. 3B shows a C-shape by cutting a part of the short cylinder, and the ring shown in FIG. 3C is a short coiled ring.
[0015]
The elastic ring 29 may be attached to the large outer diameter portion 24 in any manner other than the illustrated example. For example, the ring 29 may be fixed to the outer surface of the large outer diameter portion by an appropriate method.
[0016]
FIG. 4 shows a modification of the first embodiment. In this modification, the throttle cylinder 25 is attached to the lower end of the cylinder portion of the ironing cylinder member. In such a case, the tapered protrusion 16 attached to the outer surface of the application rod 14 is also provided below and provided at a position where it can be pressed against the upper surface of the aperture cylinder 25.
[0017]
The mounting of the ironing cylinder member 21 in the mouth-and-neck portion 3 is performed by elastically deforming the ring 29 and the large outer diameter portion 24 and pushing them into the mouth-and-neck portion 3 and forcibly pushing them down below the mouth-and-neck portion.
[0018]
The container having the above configuration is used by unscrewing the cap and pulling out the coating member 11 from the state where the cap 12 is tightened to the container body neck as shown in FIG. At the time of drawing, the inner edge of the drawing cylinder 25 comes into contact with the outer surface of the application rod 14 and the liquid adhering to the application rod is scraped off, and the inner edge of the drawing cylinder reduces the outer diameter of the application part 15 by elastic deformation and allows it to pass through. The excess liquid adhering to the application part is removed.
[0019]
After the application is completed, the upper surface of the throttle cylinder 25 and the lower surface of the tapered protrusion 16 are reattached, and the upper surface of the outer flange 23 of the ironing cylinder member and the lower surface of the outer flange portion 17 of the upper end of the application rod 14 are in watertight contact with each other. To prevent liquid leakage when the container falls.
[0020]
【The invention's effect】
The present invention has the above-described configuration, and the strength of the ironing cylinder member 21 formed of an elastic material such as rubber is weakened by the structure described in claim 1 so that the inner surface of the mouth and neck part is engaged with the lower inner surface. Even if the large outer diameter portion 24 is easily deformed, a separate elastic ring 29 is attached to the large outer diameter portion, so that the elastic ring reinforces the large outer diameter portion 24 and thus the application rod. 14 It is possible to prevent the ironing cylinder member 21 from being pulled out together with the application rod during drawing.
