Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a cap with a spout for opening and closing a container accommodating liquid cosmetics and seasonings.

[Conventional technology]

Conventionally, as this kind of cap with a spout, for example,
There is one disclosed in Japanese Utility Model Publication No. 56-49899. This cap with a spout is attached with a cap body 3 of a rim 2 of a container 1, and this cap body 3 is provided with a spout collar portion 4 for preventing liquid dripping at the time of spouting, Further, a bottom plate portion 7 having a pull ring 5 and a score line 6 which is broken by pulling of the pull ring 5 is provided, and the bottom plate portion 7 seals the liquid in the container 1 at the time of product shipment. That is, at the time of pouring and using, the opening for temporary sealing defined by the score line 6 is broken and removed, and the container 1 is opened so that the liquid inside can be poured. Also, in order to keep the contents sealed for the next use,
The cover cap 8 that opens and closes the inside of the container 1 by engaging with and disengaging from the pouring collar portion 4 on the side of the cap body 3 has a hinge portion 9 that can be freely opened.
Has a structure integrally molded.

[Problems to be solved by the invention]

However, in this conventional cap with a spout, the cap body 3 has a complicated integrated structure in which the spout collar 4, the pull ring 5, the bottom plate 7, and the cover cap 8 are main members. In addition, the die for molding is extremely complicated, which is a major cause of high manufacturing cost.

The opening defined by the score line 6 in the bottom plate 7 for temporary blockage is preferably made of a soft material as a whole including the bottom plate 7 in order to facilitate breakage. . In consideration of these points, if the material around the bottom plate portion 7 is set to be soft, the cap body 3 including the cover cap 8 and the hinge portion 9 is generally forced to select a soft material. Therefore, sufficient fitting strength of the cap body 3 with respect to the rim 2 of the container 1 of the cap body 3 cannot be obtained, and also in the hinge portion 9, required rigidity as an opening / closing fulcrum of the cover cap 8 can be obtained. There is a problem that it does not exist.

The present invention has been made in view of such problems of the conventional cap with a spout, and aims to reduce the die cost,
It is an object of the present invention to provide a cap with a spout, which can obtain a required rigidity strength as a plug body.

[Means for solving problems]

In order to solve such a conventional problem, the cap with a spout according to the present invention has the following structure.

That is, in the resin cap body 12 that is fitted into the mouth edge 11 of the container 10 and opens and closes, the mouth edge 11 can be fitted into the cap body 12 by being sandwiched from the outer peripheral side and the inner peripheral side. The outer cylinder portion 13 and the inner cylinder portion 14 are doubly provided.

Further, a bottom plate portion 16 that closes the inner cylinder portion 14 is provided.
A pull ring 19 for breaking the thin wall break line 17 was provided on the surface of the thin wall 16 opposite to the inner cylindrical portion 14 for opening the container 10 by disconnecting the thin wall break line 17.

The bottom plate portion 16 on the pull ring 19 side is further provided with a ring-shaped pouring collar portion 15 for preventing liquid dripping during pouring.

Separately from the cap body 12 having such a structure, a cover cap 20 sized to close almost the entire cap body 12
Is integrally formed with the cover portion 24 of the cover cap 20. The bearing portion 21 by the reversing hinge is integrally provided, and the tongue-shaped fixing plate 22 is integrally provided so as to project from the bearing portion 21.

The fixing plate 22 of the cover cap 20 is closely fitted into the locking hole 13a formed in the bottom plate portion 16 of the cap body 12 to fix the fixing plate 22.
The cover cap 20 is attached to the cap body 12 by hooking the hooking projection 25 provided at the tip of the lower edge of the outer cylindrical portion 13.

[Action]

When starting pouring for the first time as a product, the cap body 12 is opened via the bearing portion 21 in the direction of reversing. From this, by pulling the pull ring 19 to break the thin break line 17 and separating the separating portion 18 from the bottom plate portion 16 to eliminate it, the container
Open 10. After pouring out the required amount, the entire cap body 12 is closed by the cover cap 20 to prepare for the next use.

〔Example〕

Hereinafter, embodiments of the cap with a spout according to the present invention will be described with reference to the drawings. In FIGS. 1 and 2, an undercut portion 11a is provided on the rim 11 of the container 10, and the cap body 12 of the resin molded product is dropped into the rim 11 with one touch through the undercut portion 11a. Moreover, it can be mounted with the required fitting strength. The cap body 12 side has a structure in which the outer cylinder portion 13 and the inner cylinder portion 14 are doubled, and the rim 11 of the container 10 is inserted into the gap between the both cylinder parts, and the rim 11 side It is adapted to be engaged with the undercut portion 11a.

Further, a spout collar portion 15 for preventing liquid dripping protrudes upward on the side opposite to the inner and outer cylindrical portions 13 and 14, and the tip opening edge 15
"a" bends outward with a gentle curvature to prevent dripping during pouring. This spout collar 15 and the inner cylinder
A bottom plate portion 16 is provided in such a manner as to separate it from 14 and the bottom plate portion 16 is provided with a separating portion 18 having an area surrounded by a thin break line 17. A ring-shaped pull ring 19 is provided on the upper surface side of the separating portion 18 so as to be surrounded by the spout collar portion 15. The pulling of the pull ring 19 breaks the thin break line 17 so that the separating portion 18 is removed.

That is, the separating portion 18 is for temporarily sealing the liquid in the container 10 at the time of shipping the product, and when the separating portion 18 is removed, the container 10 is opened and the liquid inside can be poured out.

On the other hand, in order to seal and store contents such as liquid for the next use, the cap body 12 is disengaged from the spout flange portion 15 and the cover cap 20 opens and closes the container 10. . The cover cap 20 is separate from the cap body 12,
It is formed as a single body, has a cover portion 24 of a size that closes almost the entire cap body 12, and a bearing portion 21 by a well-known reversing hinge is integrally provided on the cover portion 24.
A tongue-shaped fixing plate 22 is provided so as to integrally project from the. The bearing 24 allows the cover 24 to rotate with respect to the fixed plate 22.
