Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a cap for a container such as a bottle, and more particularly to a cap that can be opened and closed with one touch.

(Prior art) Containers for soy sauce, sauces, etc. are always kept on the dining table and the caps are opened and closed as needed. They are also required to be excellent in their abilities.

In a conventionally known cap consisting of a main body and a lid, the main body side and the lid side are separate bodies, and the lid is removed each time it is used.

In addition, many have a pull-top spout, which is opened by tearing off the top of the main body. After being torn and opened, it remains open at all times.

(Problems to be Solved by the Invention) However, the conventionally known caps have the following drawbacks.

The main body of the cap and the lid are separate pieces (so there is a risk of losing the lid after opening it and using it, and if you lose the lid, you will not be able to use the container and you will have to replace it with a new one). The container will have to be replaced.

Furthermore, when closing the lid after use, the lid and the main body are separate bodies, so the user has to search for the lid, so it is not easy to close the lid.

Furthermore, when the pull-top type is sealed at -rI4, the spout remains open at all times, resulting in poor airtightness. Conventionally known caps have a cylindrical spout and are designed to contact and seal by bringing the back side of the lid into contact with the upper end of the spout. J-closed, there was a risk that a gap would be created and the sealing accuracy would be insufficient.

Furthermore, with conventionally known caps, there is a risk that contents such as soy sauce dripping from the spout may spill out of the cap, staining the container or staining the hands of the user.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to improve the above-mentioned lack of a conventionally known cap, to prevent loss of the cap lid, to make it easy to open and close the lid, and to ensure the sealing of the lid. To provide a cap that prevents the main body and container from being soiled by objects.

(Means for solving problems) The present invention is characterized by the following configuration.

That is, in a cap made of a molded synthetic resin,
It consists of a main body consisting of a cylindrical part and an upper surface part, a lid consisting of a cylindrical part and a top plate part, and a connecting part that integrally connects the main body and the lid, and is formed at the center of the upper surface part of the main body. a trumpet-shaped spout formed surrounding the opening; a slit provided in the spout; a cylindrical protrusion formed on the outer periphery of the upper surface; and an outer periphery of the upper end of the cylindrical protrusion. an engaging step portion formed in the cylindrical portion; a accommodating portion surrounded by the cylindrical projection; a groove formed in the accommodating portion and communicating with the opening via the slit; and an inner periphery of the cylindrical portion of the lid. an engagement step formed in the main body and engaged with an engagement step formed in the cylindrical protrusion of the main body; and a sealing part formed in the center of the top plate part of the lid and inserted into the opening of the main body. and to have.

Referring to the figure, a cap 1 is made of a molded synthetic resin and includes a lid 2 and a main body 3.

The lid 2 is fitted into a main body 3, and the main body 3 is screwed into or fitted into the opening 4 of the container.

The main body 3 has a cylindrical portion 3. and an upper surface portion 3□, and a thread 5 is cut on the inner periphery of the cylindrical portion 31, so that it is configured to be screwed into the threaded portion of the mouth portion 4 of the container. Incidentally, it is also possible to provide a structure in which an engagement step for fitting is provided on the screw 5 and engages with a locking step on the mouth portion 4 of the container.
is formed to prevent the cap 1 from slipping when rotating.

An open lower part from which the contents of the container are poured out is formed in the center of the upper surface part 3□, and a trumpet-shaped spout 8 is formed surrounding the open lower part. The trumpet-shaped spout 8 is provided with a slit 9, and a part of its outer periphery is cut out by the slit 9.

Further, a cylindrical projection 10 is formed on the outer periphery of the upper surface portion 3□, and at the same time as the cylindrical projection 10 engages with the lid 2, which will be described later,
It also serves as a wall that accommodates the contents dripping from the spout 8 so that it does not leak to the outside. An engaging stepped portion 10 is formed on the outer periphery of the upper end of the cylindrical projection 10 .

A groove 12 is formed in the housing part 11 surrounded by the cylindrical projection 10, and the groove 12 communicates with the open lower part through the slit 9.

M2 is integrated with the main body 3 via the connecting part 13,
The lid 2 consists of a cylindrical portion 21 and a top plate portion 2□. An engagement step portion 14 is formed on the inner circumference of the cylindrical portion 21, and the engagement step portion 1
Reference numeral 4 denotes an engagement step portion 1 formed on the cylindrical projection 10 of the main body 3.

A cylindrical sealing part 15 is formed in the center of the top plate part 22, and the sealing part 15 is inserted into the lower part of the main body 3 to prevent the contents contained in the container from leaking out. A brim-shaped projection 16 is partially formed on the outer periphery of the lid 2,
The lid 2 is opened and closed by the flanged projection 16.

(Function) The function of the cap of the present invention configured as described above will be explained.

The lid opening action is performed by pushing up the flange-like projection 16 formed on the lid 2 with a finger. Even after the lid is opened, the lid 2 remains connected to the main body 3, so there is no chance of losing the base unlike in the conventional case.

When pouring the contents of the container, the container is tilted and the contents flow out from the spout 8. After pouring, the contents dripping from the spout 8 are poured into the container 1 surrounded by the cylindrical protrusion 10.

The lid closing action is performed by placing the lid 2 over the main body 3 and engaging the engaging step 14 of the lid 2 with the engaging step 101 of the cylindrical projection 10 of the main body 3. This action can be performed easily since the lid 2 is connected to the main body 3, so there is no need to search for M2. In the wi lid state, lid 2 is sealed! '1S15
is inserted into the open lower part of the main body 3, so that the contents are reliably sealed.

Also, when removing the cap 1 from the mouth 4 of the container, the main body 3
Since the unevenness 6 is formed on the outer periphery of the cap 1, the cap 1 can be rotated without slipping, and the cap 1 can be easily removed.

The above is only one example of the present invention, and the present invention is not limited to the above-mentioned example, but naturally includes various modified structures that encompass the spirit of the present invention.

(Effects of the Invention) Since the main body of the cap and the lid are connected, there is no risk of losing the lid after it is opened and used.

Furthermore, when closing the lid after use, there is no need to search for the lid, making the lid closing operation easier.

Furthermore, the spout is reliably sealed, reducing leakage and deterioration of the contents.

Furthermore, the contents dripping from the spout will not spill to the outside of the cap, and will not stain the container or the user's hands.

Moreover, since the contents dripping from the spout are returned to the container, the contents do not stick to the inside of the cap, and the cap can be used cleanly at all times.
