Abstract

PROBLEM TO BE SOLVED: To provide a highly airtight enameled vessel having a function preventing the bottle mouth from being stained by the contents and having a superior effect preventing the viscosity of the content from increasing during the storage. SOLUTION: The wall thickness of the bottle mouth 2 is gradually narrowed toward the vicinity of the top face 5. An inner seal 8 fitted in the internal circumference of the bottle mouth 2 and a main seal 7 into which the top face 5 of the bottle mouth 2 is bitingly abutted are provided in a cap 3 so that the content in the vessel is hardly accumulated on the top face 5, when the content of the vessel is taken out with its stuck to the brush, and the contact pressure between the top face 5 and the main seal 7 in attaching the cap 3 is enhanced so as to secure the air tightness.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a highly airtight enamel container and, more particularly, to an enamel container having a function of preventing contamination of a bottle mouth and easily ensuring airtightness of the container after use.

[0002]

2. Description of the Related Art In a conventional enamel container, as shown in FIG. 5, for example, a brush (4) is attached to a cap (3) attached to a bottle mouth (2) of a container body (1).
The contents adhered to the brush (4) should be used after adjusting the amount of adhesion to the brush (4) by squeezing the inner corner of the bottle mouth (2) as shown in FIG. There are many. Usually, the top surface (5) of the bottle mouth (2) is pressed against the inner surface of the cap (3) to secure airtightness during storage.

However, conventionally, the top surface (5) of the bottle mouth (2)
Is formed on a plane perpendicular to the axis of the bottle mouth (2) as shown in FIG. 7, or a small rib (6) is formed at the center of the top surface (5) formed as a plane as shown in FIG. ) Was formed. Therefore, when the enamel product adhered to the brush (4) is squeezed at the inner corner of the bottle mouth (2) as described above, the scraped-off contents are as shown in FIG. 7 and FIG. Top surface (5)
Dirt is generated in the bottle mouth (2) because it easily accumulates in the bottle, or
As shown in FIG. 9, the content adhering to the top surface (5) is interposed between the sealing surface of the cap (3) and the airtightness is reduced. A phenomenon that an increase in the content viscosity was observed was observed.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to provide a highly airtight enamel container which is excellent in the function of preventing the contents of the bottle from being stained by the contents and the effect of preventing the rise in the content viscosity during storage.

[0005]

In order to solve the above-mentioned problems, the present invention adopts an inner seal in which the thickness of the bottle mouth is gradually reduced in the vicinity of the top surface and is fitted to the inner periphery of the bottle mouth. And a cap provided with a main seal in which the top surface of the bottle mouth bites into contact.

This invention is characterized in that the inner seal and the main seal are formed at the base of the brush inserted into the cap. Furthermore, this invention is that at least one of the inner periphery and the outer periphery of the bottle mouth is constituted by an inclined surface so that the thickness of the bottle mouth is gradually reduced in the vicinity of the top surface, or the top surface of the bottle mouth is constituted by an arc surface. It is characterized by.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in detail with reference to the drawings. In addition, FIG.
Portions having the same functions as those of the conventional example shown in FIG. 9 are denoted by the same reference numerals, and detailed description thereof will be omitted. A brush (4) is attached inside a cap (3) which is screwed and fixed to a bottle mouth (2) constituting an upper end opening of a container body (1) formed of a molded product of glass in FIGS. Thus, an enamel container capable of removing the contents accommodated in the container body (1) by attaching the contents to the brush (4) is constituted.

Here, in the present invention, the bottle mouth (2)
Is gradually reduced near the top surface (5). Specifically, by forming the inner and outer peripheral surfaces of the bottle mouth (2) with inclined surfaces respectively, the bottle mouth near the top surface (5) is formed.
(2) The thickness is gradually reduced, and the top surface (5) is constituted by an arc surface.

[0009] The top seal (5) formed by the arc surface as described above bites into contact with the main seal (7) and the inner seal (8) formed by a ridge fitted on the inner periphery of the bottle mouth (2). Is formed at the base of the brush (4) inserted into the cap (3).

Therefore, even when the thickness of the bottle mouth (2) is made sufficiently large from the viewpoint of strength, since the thickness of the bottle mouth (2) is gradually reduced near the top surface, Even when the brush (4) with the contents adhered thereto is squeezed at the inner corner of the bottle mouth (2), the absolute amount of the contents remaining on the top surface (5) is reduced.

In particular, when the top surface (5) is constituted by an arc surface as in this embodiment, the contents adhering to the top surface (5) flow down to the inner periphery or the outer periphery of the bottle mouth (2) by its own weight. Hardly remains on the top surface (5). Therefore, even when the cap (3) is attached, the contents are not sandwiched between the top surface (5) and the main seal (7), and the airtightness between the top surface (5) and the main seal (7) is maintained. The nature becomes high. Furthermore, since the cross section of the bottle mouth (2) is gradually reduced, the contact pressure between the top surface (5) and the main seal (7) is increased, and the top surface (5) is easily digged in, so that higher airtightness is maintained. Is done.

Further, the inner seal (8) is fitted on the inner periphery of the bottle mouth (2) to further improve the sealing effect of the main seal (7) and is left on the inner periphery of the bottle mouth (2). Since the contents are forcibly pushed back by the inner seal (8), the effect of preventing the bottle mouth (2) from being stained is improved.

In the above embodiment, the top surface (5) is constituted by an arcuate surface so that the top surface (5) bites into the main seal (7) more effectively and the function of preventing the contents from remaining remains. Although the height is increased, for example, when the top surface (5) of the bottle mouth (2) whose cross section is gradually reduced as in the embodiment shown in FIG. 3 and FIG. It is possible to further enhance the ironing effect of the removed contents.

Further, in each of the above embodiments, the vicinity of the upper end of the inner peripheral surface and the upper peripheral portion of the outer peripheral surface of the bottle mouth (2) are both constituted by inclined surfaces, and the cross section is gradually reduced. The same operation and effect can be obtained when only one of the inner peripheral surface and the outer peripheral surface is constituted by the inclined surface and the cross section is gradually reduced.

[0015]

According to the highly airtight enamel container of the present invention, the area of the top surface can be reduced without impairing the strength of the bottle mouth, thereby reducing the amount of adhesion of contents caused by brushing of the brush and the cap. Since the bite into the main seal formed on the side can be improved, the deterioration of the airtightness due to the adhesion of the contents to the top surface of the bottle mouth can be avoided, and the mouth of the contents due to volatilization can be prevented. It is possible to effectively avoid solidification of the contents and an increase in the contents viscosity.

According to the second aspect of the present invention, since the main seal and the inner seal, which require elasticity, can be constituted by separate parts from the cap, which requires rigidity, the hermeticity of these seals is reduced. Can be higher.

According to the third aspect of the invention, the appearance of the bottle mouth can be diversified based on the design elements. Can be more effectively reduced, and damage to the top surface can be avoided.
