Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a cap with a spouting tool constructed by slidably fitting the spouting tool into the spout of a container.

Conventional containers with a structure in which a pouring tool is arranged so that they can be freely retracted and retracted are disclosed in Japanese Utility Model Publication No. 42-5802 and Japanese Utility Model Publication No. 4, 1973.
This is already known through the inventions published in the publications of No. 3-15335, Japanese Utility Model Application No. 51-148710, and Japanese Utility Model Publication No. 52-38530.

However, the structure of the cap with a spouting device according to each of these inventions is such that the cap is closed only by the spouting device being removably fitted onto the mouth and neck of the container.
A separate protector is required for the seal at the container pouring part, and the closing function after opening must rely on the cap attached to the pouring device itself, which not only has the disadvantage of poor sealing effect, but also In addition to equipping the mouth and neck of the container with an inner stopper to support the pouring tool so that it can freely come out and go out, the cap for the pouring tool must be attached by extending the connecting piece, making the configuration complicated and the unit price expensive. Not only that, but the diameter of the dispensing tool is generally small, and the operation of attaching and detaching the cap is complicated, and if it is attached to the neck of the container,
This has drawbacks such as difficulty in drawing out this.

Therefore, the present invention consists of a structure in which a cap is screwed or fitted onto the spout of the container, and by applying the spouting tool, the inner plug is an essential requirement in order to slidably support the spouting tool. In addition, the cap of the dispensing tool is made unnecessary, the structure is simplified, the dispensing operation is simplified and quickened, and the dispensing device can be provided at a low cost. while protrudingly provided with an annular collar on the cylindrical portion on the front end side of the dispensing tool, which is attached to the mouth neck of the container and tightly closes the opening of the dispensing tool by the pressing action of the pressing cylindrical section; This makes it possible to improve the operability of opening/closing the dispensing tool and improve the water quality.Furthermore, by providing a tension piece protruding from the cylindrical portion on the front end side of the dispensing tool, the dispensing tool can be easily opened and closed from the neck of the container. This device has been devised to overcome the above-mentioned drawbacks of the conventional device by making the withdrawal operation easy.

An embodiment of the cap with a pouring tool of the present invention will be described below with reference to the drawings.

1 is a container, 2 is a pouring spout provided at the opening of the container 1, a screw portion 3 is provided on the outer periphery of the spout 2, and a mouth portion 5 having an opening is provided in the upper center portion. .

An inner ring 8 with a diameter corresponding to the inner diameter of the cylindrical portion on the front end side of the spouting tool, which will be described later, is protruded from the inner center of the top plate 7 of the cap 6, and also corresponds to the neck portion 5 of the spout portion 2. A pressing cylindrical portion 9 is provided in a protruding manner.

Reference numeral 10 denotes a dispensing tool; in this embodiment, the dispensing tool 4 is formed of a tube whose middle part is bent in a dogleg shape to facilitate dispensing when the dispensing tool 4 is pulled out; however, the present invention is not limited to this. The spout portion 2 may be straight.
It is slidably inserted into the mouth and neck part 5 of the body.

Also, both front and rear ends 10a, 10 of this pouring tool 10
b includes a cylindrical portion 11.1 that fits into the mouth and neck portion 5 of the spout portion 2;
2, a ring-shaped tension piece 15 is provided on the outer periphery of the fitting cylinder part 11 on the front end side via an annular collar 13 and a bridge 14, and a ring-shaped tension piece 15 is provided on the outer periphery of the fitting cylinder part 11 on the rear end side. This is formed by providing an engaging edge 16 for the spouting section 20 and the neck section 5.

Furthermore, the thickness of the dispensing tool may be tapered toward the distal end as a means to improve liquid drainage.

The cap with a spouting tool of the present invention has the above-mentioned configuration, and to explain how to use it, as shown in the first figure, the cap with a spouting tool 10 is slid inside the neck 5 of the container 1 and placed inside the container 1. While recessed, the front end portion 10a
After fitting the side fitting cylinder part 11 to the spout and neck part 5 while tightly engaging the annular flange 13 of the fitting cylinder part 11 to the opening edge 5a of the spout and neck part 5, the screw of the spout part 2 is screwed. By screwing the cap 6 onto the portion 3, the spout portion 2 of the container 1 can be closed.

When pouring out the contents of the container 1 from the spout 2, the cap 6 is taken out from the spout 2, and then the spout 10 is inserted into the spout while pinching the tension piece 15 with your fingers. By pulling out the mouth and neck part 5 of No. 2 to the outside and fitting the fitting cylinder part 12 on the rear end 10b side while engaging the engagement edge 16 provided at the end with the root end 5b of the mouth and neck part 5. ,
It protrudes to the outside of the spout part 2, and the container 1 is inserted through the spouting tool 10.
The contents can be poured out into a desired container.

Now, when using the above-mentioned cap with a spouting tool of the present invention, the operation of pulling out the spouting tool 10 is performed using the tension piece 15 provided on the outer periphery of the fitting cylinder part 11 of the front end 10a via the bridge 14.
Since it can be pulled out while pinching it with your fingers, compared to the conventional product which is simply composed of the fitting cylinder part 11,
The operation of pulling out the pouring tool 10 can be performed easily.

Since the structure of the tension piece 15 is provided for the above-mentioned purpose, it is not limited to the structure in which the ring-shaped tension piece 15 is provided protrudingly through the bridge 14 of the embodiment. As shown in FIG. 6, by providing an annular flange 13 on the outer periphery of the fitting cylinder part 11 of the spout 10 and protruding a tongue-shaped tension piece 20, the fitting cylinder part 11 of the pouring spout 10 can be pulled out. Of course, it is also possible to carry out the process while making design changes such as making it possible to carry out the process while pinching the tension piece 20 with fingers.

Furthermore, by forming the annular flange 13 with a wide width or integrally protruding a large number of protrusions along the periphery of the annular flange 13, it is possible to expect the same pull-out operability as described above, and these same effects can be expected. All structures capable of exerting these functions are included in the structure called a tension piece.

Furthermore, according to the configuration of the cap with a spouting tool of the present invention, an annular flange 13 corresponding to the diameter of the mouth and neck part 5 of the spout section 2 of the container 1 is provided on the outer periphery of the fitting cylinder part 11 of the spouting tool 10, while the cap 6 is Since the inner ring 8 which can be fitted into the fitting cylinder part 11 of the spouting tool 10 and the pressing cylinder part 9 corresponding to the neck part 5 are provided protrudingly, the fitting cylinder part 11 of the spouting tool 10 can be fitted into the mouth and neck part 5. After fitting, the cap 6 is inserted into the spout 2 of the container 1.
By screwing into the threaded part 3, the opening of the spouting tool 10 and the mouth and neck part 5 of the spout part 2 of the container 1 are closed completely watertight by the pressing action of the inner ring 8 and the pressing cylinder part 9. It is something that can be done.

Furthermore, by screwing the cap 6 onto the spout 2 of the container 1, the spout 10 and the spout 2 of the spout 2 can be screwed together.
According to a configuration that can simultaneously close the above-mentioned conventional spouting tool, the cap of the spouting tool itself, the inner stopper for slidably supporting the spouting tool, and the spout part of the container itself are sealed. It has the effect of eliminating the need for all structures such as a stopper required for pouring, and has the advantage that capping can be easily done using the conventional method of screwing the cap 6 onto the spout 2. able to demonstrate.

Further, a pilfer-proof mechanism such as a ratchet mechanism and perforations may be provided near the flat ends of the spout 2 of the container 1 and the cap 6, respectively.

As described above, due to the above-mentioned structure and the effect of simplifying capping, etc., the product unit price of this type of cap can be significantly reduced, and therefore, this type of cap can be expected to be applied to a wide range of containers.
