Description

[Detailed Description of the Invention] "Industrial field of application" The present invention relates to a hinge cap with a tear piece for partial opening, which is used as a cap for filling containers such as seasonings and sprinkles.

"Prior Art" Conventionally, a double hinge cap for opening and closing a part of a cap body of a container is provided on a top plate of the cap body, but a small opening formed in a part of the container is directly closed by the double hinge cap. The opening was not sufficiently sealed and it was necessary to separately seal the double hinge cap and the cap body (Actual No. Sho 58-3462). In addition, a product was developed in which a tear piece was provided in the small opening through an endless tear groove, and the small opening was sealed. However, the pulling piece (pull ring) provided in the tear piece was used as the tear piece.
Since it was erected between the heavy hinge cap and the double hinge cap, a pull ring accommodation space was required between the tear piece and the double hinge cap.
There is a problem that it is difficult to form the cap body low.

[Problems to be Solved by the Invention] The present invention is to provide a double hinge cap in a part of a cap body of a container, a tear ring for closing an opening part provided in the part, and a pull ring, and further for the above part. It is an object of the present invention to obtain a low cap by closely contacting a double hinge cap with a double hinge cap and to obtain a simple and hygienic partial can opening cap which can seal the opening can with a tear piece.

[Means for Solving the Problem] In order to achieve the above-mentioned object, the present invention comprises a side plate and an upper plate, and an upper lid that overlaps with a part of the upper plate is pivotally attached to the upper plate so as to be openable and closable. A hinge cap formed integrally with a synthetic resin in which an opening can is formed in a part, wherein the opening can connects the part and a tear piece for opening a can through an annular thin film to close the opening. The upper surface of the tear piece is lower than the part, and the tear piece is provided with a tab, and the fitting groove of the tab is opened to the outer periphery of the part to fit into the opening can. In addition, the hinge cap with the tear piece for partial opening can has a convex surface formed on the upper surface of the tear piece on the lower surface of the upper lid.

"Operation" Therefore, when the side plate 1 of the hinge cap is fitted into the opening of the container and the opening is closed, the opening can 5 is closed by the annular thin film 7 and the tearing piece 6 for opening. In that state, when the upper lid 3 is superposed on the above-mentioned portion 2'and closed, the projection 9 is formed.
Fits into the open can 5, and is superposed on the upper surface of the tear piece 6,
The lower surface of the upper lid 3 and the upper surface of the portion 2'are overlapped with each other. When the can is opened, the upper lid 3 is opened upward around the pivotal attachment portion 4 (hinge), and when the knob 8 is grasped and pulled upward, the annular thin film 7 is torn and the tear can 6 for opening can is part of the above. It is separated from 2'and the opening can 5 opens. Then, the contents in the container can be discharged from the opened can portion 5. When the upper lid 3 is closed, the opening can 5 is also closed, and when the convex surface 9 is fitted into the opening 5, the opening 5 is closed when the upper lid 3 is closed.

[Embodiment] An upper plate 2 is provided on the upper end of a short cylindrical side plate 1, and an arc-shaped upper lid 3 overlapping an arc-shaped portion 2'of the upper plate 2 is pivotally attached to the upper plate 2 in an openable and closable manner. This pivotally attached portion 4 (hinge portion) is the upper lid 3
It is a chord part and is thin so that it can be bent. An opening can 5 is formed at the center of the arc-shaped portion 2'and is integrally molded with a synthetic resin (for example, PP) to form a so-called hinge cap (meaning a cap in which the upper lid 3 is connected by the hinge). Form). The opening can 5 thus formed is closed by integrally connecting the portion 2'and the tearing piece 6 for opening the can via the annular thin film 7, and the upper surface of the tearing piece 6 is the same as that of the portion 2 '. It is placed lower in the can opening portion 5 than the upper surface (FIGS. 4A and 4B). Further, the tear piece 6 is provided with a pull ring type gripping piece 8 as shown in FIGS. 1 and 3 (c) and a tongue-shaped gripping piece 8 as shown in FIGS. 3 (a) and (b). The lower surface (back surface) of the upper lid 3
A convex surface 9 that fits into the open can 5 is formed in the central portion, and when the upper lid 3 is partially overlaid on the portion 2 ', the convex 9 can be fitted into the open can 5 and hermetically sealed. There is no problem even if perforations 10 are formed in the annular thin film 7 as shown in FIG. Reference numeral 11 in the drawing denotes a tip engaging claw of the upper lid 3, and 12 denotes a claw formed on the part 2'for engaging with the engaging claw 11. Reference numeral 13 is a fitting groove for the knob 8.

[Advantage of Invention] Since the present invention is constructed as described above, the double upper lid 3 is pivotally attached 4 to the portion 2'of the cap body, and the upper lid 3 and the portion 2 '.
In addition to forming a low and simple cap by polymerization, the open can 5 formed in the portion 2'is sealed by the tear piece 6 through the annular thin film 7 and the pick 8 is attached to the portion 2 '. ′ Can be protruded outward from the outer circumference of the can, and the opening can 5 can be easily opened by the knob 8, and after opening, the opening 5 can be sealed by the convex surface 9 of the lower surface of the upper lid 3 to provide a thin and low cap that is easy to use. effective.
