Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a container for detergent liquid, etc., in which a cap having an inner ring is fitted.

[Prior Art] Conventionally, as a container for detergent liquid, etc., a container fitted with a set of upper and lower caps has been used. In this case, the lower cap is a main body cap fitted onto the container main body, and the upper cap is a metering cap detachably fitted onto the main body cap.

[Problems to be solved by the invention] This type of container is convenient because it can be used without waste while measuring the amount of liquid with the measuring cap. There was a problem in that gaps were formed and liquid leakage occurred. That is, the main body cap usually has a depressed central part, and a spouting part is erected in a cylindrical shape from the central part and protrudes outward, and the measuring cap is connected to the measuring cup part that can measure a certain amount, and then the dispensing part. An inner ring is provided on the lower surface side of an outward flange formed at the boundary between these parts, and this inner ring is brought into close contact with the inner wall of the outer ring of the main body cap to form a seal with the main body cap. However, defects in this seal part are the cause of liquid leaks.

In particular, if the inner wall of the outer ring of the main body cap is scratched, the adhesion with the inner ring will deteriorate, resulting in liquid leakage.

This also applies when a cap having an inner ring is directly fitted onto the mouth of a container.

[Means for Solving the Problems] The present invention was made in order to solve the above-mentioned problems of the conventional art. The main feature is that a stepped portion is provided on the upper edge of the inner wall that the inner ring contacts.

[Function] With the above configuration, even if the upper edge of the vertical wall of the stepped portion is damaged, the inner wall surface in contact with the inner ring will not have a negative effect on the adhesion, so that sealing performance can be reliably maintained. I can do it.

[Example] This invention will be explained in more detail below with reference to the illustrated example.

Reference numeral 1 designates a main body cap that is screwed onto the upper end of the container 2. A stepped portion 1a is formed on the upper edge of the inner wall at the open end, and a spouting portion 1b is erected in a cylindrical shape in the depressed center portion. A screw 1c is provided on the outer wall of the lower part of the spout. 3 is a measuring cup capable of measuring a certain amount; a female threaded cylinder 3a is formed at the bottom to be screwed into the screw 1c;
An inner ring 3c is provided on the lower surface side of the outward flange 3b formed at the boundary between the measuring portion and the female threaded tube.

This measuring cup 3 is detachably attached to the main body cap 1, and when the female thread cylinder 3a is screwed into the screw 1c of the main body cap 1, it closes the open end of the main body cap 1 and inserts the inner The ring 3c is adapted to come into close contact with the inner wall of its open end. In this case, the inner ring 3c is
Since the main body cap 1 is in close contact with the open end slightly below the stepped portion 1a, even if the upper edge of the vertical wall of the stepped portion 1a has a chip or other damage,
The adhesion of the inner ring 3c is not impaired and the sealing performance can be reliably maintained. Therefore, liquid leakage from this part is prevented.

Moreover, as shown in FIG. 2, the upper edge P of the inner wall surface of the main body cap 1 is located one step lower due to the stepped portion 1a, so the upper edge Q of the vertical wall of the stepped portion 1a
Even if the P part and the lower part of the P part are damaged, the P part and the lower part of the P part will be sufficiently protected.

Incidentally, this invention can also be applied to the case where a cap having an inner ring is directly fitted to the open end of the container.

[Effects of the invention] As explained above, according to this invention, a stepped portion is provided on the upper edge of the inner wall at the open end of the container (including the main body cap), so that the inner ring of the cap that is attached to and removed from this open end is This provides excellent practical effects such as ensuring tight contact, improving sealing performance, preventing liquid leakage, and protecting the tightly adhered inner wall surface from damage caused by external factors as much as possible.
