Abstract

<P>PROBLEM TO BE SOLVED: To provide a container equipped with a cap with a brush for storing a necessary liquid to be applied, which exhibits excellent closure effects to prevent the liquid from leaking. <P>SOLUTION: A cylindrical suspended piece 6 is concentrically suspended inside a cap body 3 and outside a handle-like lever 4. The hanging piece 6 has its lower end split into two branches, thereby forming an outer split piece 6a and an inner split piece 6b suspended longer than the piece 6a. The external surface of the piece 6b is a tapered spherical surface 6c, with its tapered degree is such that a wider diameter part is larger than an opening diameter of a mouth 2 and its narrower diameter part is smaller than the opening diameter of the mouth 2. The tapered spherical surface 6c comes into pressure contact with a suspended spherical surface 2c of the mouth 2, whereby the mouth is sealed. In addition, such a dimensional setting is made that when they are in pressure contact, the outer split piece 6a abuts on a horizontal spherical surface 2b of the mouth 2, preventing the cap body 3 from further screw-fitting and lowering. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a container provided with a cap with a brush for accommodating a required application liquid such as an application agent such as a paint, an adhesive, or a cosmetic application liquid such as manicure or pedicure.

As a conventional container of this type, a screw groove for screwing into a screw portion of the mouth portion of the container is formed in the lower half portion of the inner peripheral surface of the cap body, and the cap body is closed against the container mouth portion. There is a container provided with a brushed cap formed by integrally forming a cylindrical hanging piece for making a concentric circle with the lower surface of the top plate of the cap body. (For example, refer to Patent Document 1.)
Japanese Utility Model Publication No. 3-56557

  Hereinafter, a container having a conventional cap with a brush will be described with reference to FIG. That is, conventionally, the mouth portion e is closed by pressing the cylindrical hanging piece c integrally formed on the lower surface of the top plate b of the cap body a against the mouth portion e of the container d. It was configured to be able to.

  In the case of the conventional example as described above, the cap body a is lowered and closed along the thread groove on the container side, so that the lowering is performed while rotating in a slightly inclined state rather than in a completely horizontal state. Will be. Therefore, when the cap body a is tightened, it is difficult for the lower end edge of the cylindrical hanging piece c to maintain uniform contact with the upper surface of the mouth edge of the mouth portion e, and the cap body a is inevitably more than necessary. It was necessary to make the contact closer by screwing it into the screw. In other words, when the cap body a is normally screwed into the mouth e, uniform contact with the entire circumference of the cylindrical hanging piece c cannot be ensured, and blur (inclination occurs vertically and horizontally). This is likely to cause incompleteness of occlusion.

  Further, in the case of the conventional example described above, the sealing action depends on linear contact with the container side flat surface of the lower end edge of the cylindrical hanging piece c, so that all of them do not contact uniformly. As a result, liquid leakage occurs, and it tends to be tightened more than necessary. When such overtightening occurs, unexpected deformation based on the pressure contact more than necessary occurs at the lower end of the cylindrical drooping piece c, resulting in obstruction failure and distortion of the entire cap body a. Etc. were forced to occur.

  The present invention is intended to provide a novel “container having a cap with a brush” that solves the conventional problems as described above.

In the present invention, a horizontal peripheral surface 2b is continuously provided at the upper end, and a drooping peripheral surface 2c formed by bending vertically from the inner peripheral edge of the horizontal peripheral surface 2b is continuously provided, and a thread groove 2a is formed in the body portion. A cap 1 having a container body 1 having a mouth portion 2 and a threaded portion 3a threadedly engaged with the screw groove 2a on the inner peripheral surface, and a handle-like collar 4 having a brush 5 attached to the lower end thereof. Consisting of body 3 and
The cap body 3 is provided with a cylindrical hanging piece 6 concentrically hanging on the inner side of the cap-shaped bag 4 on the inner side thereof, and a tapered peripheral surface 6c is formed on the lower end portion of the hanging piece 6; The present invention relates to a container having a brushed cap configured to seal the mouth by bringing the tapered peripheral surface 6c into pressure contact with the suspended peripheral surface 2c of the mouth 2.

  And specifically, as the cylindrical drooping piece 6, the lower end edge portion is bifurcated to form an outer branching piece 6a and an inner branching piece 6b drooping longer than this, The outer surface side of the inner branch piece 6b is a tapered peripheral surface 6c, and the tapered shape is such that the wide diameter portion is larger than the opening diameter of the mouth portion 2, and the narrow diameter portion is larger than the opening diameter of the mouth portion 2. The taper circumferential surface 6c is set to be pressed against the suspended circumferential surface 2c of the mouth portion 2 so that the mouth portion 2 is blocked by setting the outer circumferential branch piece 6a as described above. Then, at the time when the taper peripheral surface 6c is pressed, the embodiment is configured such that a dimensional setting is made so as to prevent further screwing down of the cap body 3 against the horizontal peripheral surface 2b of the mouth portion 2. Is.

  The present invention eliminates the conventional problems as described above based on the use of the above-described configuration.

  Since the container according to the present invention adopts the configuration as described in claim 1, that is, the cap body 3 is provided with a cylindrical hanging piece 6 concentrically on the inside of the cap body 3 and on the outside of the handle ridge 4. The taper peripheral surface 6c is formed at the lower end portion of the drooping piece 6 and the taper peripheral surface 6c is pressed against the drooping peripheral surface 2c of the mouth portion 2 so that the mouth is sealed. Therefore, the container is closed based on the pressure contact of the tapered peripheral surface 6c on the cap body 3 side with the suspended peripheral surface 2c on the container body 1, that is, a kind of surface contact. Therefore, unlike the conventional occlusion based on linear contact, it is extremely stable and perfect. That is, the uniform contact of the entire circumference of the cylindrical drooping piece c, which has occurred in the prior art, cannot be ensured, and blurring occurs due to up and down and left and right (inclination occurs). This problem, which tends to cause incomplete occlusion, is completely solved in the present invention.

  As a result of eliminating the above-described problem of blurring due to inclination, the inner branch piece 6b having the tapered peripheral surface 6c serves as a guide during screwing down when the cap body is set in the container, The center is easily determined without causing left and right blurring, and therefore, for example, in the liquid filling operation line management for the container, the screwing operation of the cap body can be accomplished dramatically and easily. In other words, if the screwing is uncertain due to blurring, the filling work line management will be frustrated. However, in the present invention, such problems are eliminated.

In the container according to the present invention, as described in claim 2, the outer branch piece 6a hits the horizontal peripheral surface 2b of the mouth portion 2 at the time of the pressure contact of the tapered peripheral surface 6c, so Therefore, when the surface of the inner branch piece 6b is blocked by the tapered peripheral surface 6c, the outer branch piece 6a is formed. Thus, the screwing down of the cap body 3 is prevented, and the occurrence of a situation such as overtightening of the cap body 3 is prevented in advance. Therefore, problems such as unexpected deformation of the lower end of the cylindrical drooping piece c due to excessive tightening of the cap body, failure of obstruction due to this, and occurrence of distortion of the entire cap body a are caused by this problem. The invention is completely eliminated.
Conventionally, the leading edge of the cylindrical drooping piece 6 is sealed on the basis of the linear contact with the horizontal peripheral surface 2b of the container. The provided inner branch piece 6b is sealed by surface contact with the hanging peripheral surface 2c of the container. That is, the present invention is characterized in that there is a difference between the contact surface with the container body and the contact use portion of the hanging piece 6 of the cap body for sealing.

  In the figure, 1 is a container, 2 is a mouth projecting from the central position of the container 1, and a thread groove 2a is formed in its body. Further, the mouth portion 2 has a horizontal peripheral surface 2b continuously provided at the upper end thereof, and a suspended peripheral surface 2c formed by being bent vertically from the inner peripheral edge of the horizontal peripheral surface 2b. In the present invention, the drooping peripheral surface 2c is configured as a closing surface. Although it is a forming material of the container 1, it is usually formed of a metal material, but it may be made of a synthetic resin material. In the case of a synthetic resin, it is preferable from the viewpoint of strength that the part surrounded by the screw groove 2a, the horizontal peripheral surface 2b, and the suspended peripheral surface 2c is integrally formed with the inside filled. .

  Reference numeral 3 denotes a cap body, on the inner peripheral surface of which is formed a screw portion 3a that is screwed into the screw groove 2a formed in the mouth portion 2a of the container 1 described above. Reference numeral 4 denotes a handle-like ridge formed at the center of the cap body 3, and a brush 5 is attached to the lower end thereof. And since it is desirable that the inner branch piece 6b described later has elasticity, the cap body 3 is usually preferably formed of a synthetic resin material. Further, in the embodiment shown in FIG. 1, the handle ridge is shown in a state in which the whole is integrally formed, but this is configured so that a separate one is attached by means such as screwing. May be.

Reference numeral 6 denotes a cylindrical hanging piece, which is integrally and concentrically suspended at a predetermined position on the inner side of the cap body 3 and on the outer side of the handle ridge 4. Then, the lower end edge portion of the cylindrical hanging piece 6 is bifurcated to form an outer branch piece 6a and an inner branch piece 6b that is further hung (longer than this). .
The inner branch piece 6b has a tapered peripheral surface 6c on the outer surface side, and the inner branch piece 6b enters the opening of the mouth portion 2, and the tapered peripheral surface 6c is a drooping peripheral surface 2c of the opening portion. It is configured so that the mouth is sealed by being pressed.
When the tapered peripheral surface 6c is pressed against the suspended peripheral surface 2c of the mouth part 2 as described above, the outer branch piece 6a hits the horizontal peripheral surface 2b of the mouth part 2 and further exceeds the cap body 3. The screwing, that is, the rotation in the closing direction is prevented.

  The inner branch piece 6b is provided at a position where it can enter into the opening of the mouth portion 2 of the container 1, and the taper circumferential surface 6c has a taper degree larger than the opening diameter of the mouth portion 2 at the wide diameter portion. Further, the narrow diameter portion is set to be smaller than the opening diameter of the portion 2.

Therefore, when the cap body 3 is screwed into the mouth 2a of the container at the time of closing, the cylindrical hanging piece 6 of the cap body 3 has its inner branch piece 6b protruding into the opening, and the inner branch piece 6b Since it has a tapered peripheral surface 6c, it is configured such that when it enters a certain degree, it is pressed against the suspended peripheral surface 2c of the mouth portion 2 to exert a blocking action.
Then, when the closing action as described above is exerted, the outer branch piece 6a hits the horizontal peripheral surface 2b of the mouth portion 2, and a stopper action is provided that prevents further screwing of the cap body 3. It is comprised so that.

By the way, although it is the above-mentioned outer side branch piece 6a, when the cap body 3 is tightened somewhat strongly, it will warp a little outward as shown by the arrow in FIG. Along with this, a rotational moment is generated near the lower end portion of the cylindrical drooping piece 6, and a force that draws the inner branch piece 6b in the direction of the arrow shown in the figure, that is, a force that strongly presses the drooping peripheral surface 2c of the mouth portion 2 Will work as. In other words, the inner branch piece 6b provided with the tapered peripheral surface 6c has a lever-like action with its branch base as a fulcrum, and a force that strongly presses against the suspended peripheral surface 2c acts to increase the blocking action. It becomes.
The above-described warpage of the outer branch piece 6a is to improve the pressure contact force of the inner branch piece 6b having the tapered peripheral surface 6c, and does not expect the blocking action by the outer branch piece 6a. . That is, in the present invention, the blocking action is based solely on the surface contact of the inner branch piece 6b having the tapered peripheral surface 6c with respect to the suspended peripheral surface 2c.
