The easy-open lid of the container is a partial opening and is used for, for example, a beverage can. Canned fruit juice drinks, health drinks and low acid drinks
Currently, it is filled with liquid nitrogen and the inside of the container has a positive pressure. In particular, when juices such as fruit juice drinks and coffee drinks with milk are shaken before opening, the contents may spout if opened immediately vigorously. In addition, the hot-bender-compatible product has a higher internal pressure of the can as it is matured, and thus has a high possibility of being ejected. In the first embodiment, the contents are prevented from being blown out due to the internal pressure at the time of opening.

As shown in FIG. 3, the protrusions 7 break the radial score lines 61 from the central portion where the radial score lines 61 gather, and the triangular broken pieces 63 between the radial score lines 61 are bent and opened inward of the container body 2. Since the protrusion 7 is pushed into the opening 64,
The opening 64 is partially closed by the projection 7, and only a small gap g is formed between the projection 7 and the opening 64. Therefore, even when the opening is performed vigorously, only the gas in the container can be released without ejecting the contents. Gap g
The number of the radial score lines 61, the cross-sectional shape and the size of the protrusions 7, and the like are set so that the size of the projections is such that the distribution of the contents is blocked.

Attaching the filter 8 is an effective means. Filter 8
Paper such as filter paper or cloth such as nylon mesh is effective as the material. By attaching the filter 8, the present invention can be applied to a content containing fine particles that may be ejected together with the gas in the container from the opened degassing score 6. After the opening of the degassing score 6, the lifting portion 52 of the tab 5 elastically returns upward, and the appearance is similar to that of the conventional lid. Thereafter, as shown by the arrow in FIG. 1 (B), the tab 2 is lifted upward, and the tab nose 53 is strongly pressed against the planned opening portion 42 by the lever action to break the opening score 41. The broken pieces are folded inside the container by lifting it by more than °, and then the tab 5 is returned to its original position.

Further, it is possible to attach a filter 8 to the back surface of the gas venting score 6, and it is possible to prevent the ejection of minute contents which may be concerned when the gas venting score 6 is opened. As described above, even in the full-open easy-open lid, by providing the degassing score 6 and the protrusion 7 on the lid body 204 and the tab 5, the same spillover prevention effect as that of the first embodiment can be obtained.

吹きこぼれ防止が可能となる。This full open type container with an easily opened lid for preventing spillage is suitable for canning regular coffee and canned powdered green tea. Carbon dioxide gas is generated from the contents of the regular coffee powder during storage, so that the inside of the container becomes a positive pressure, and the content is blown out together with the gas in the container when the container is opened. Therefore, by processing the degassing score shown in the present embodiment into a lid,
The gas in the container can be released before opening to reduce the positive pressure in the container, and it is possible to prevent the ejection of coffee powder during opening. In the case of regular coffee powder, considering the particle size, it is possible to prevent spillage without installing a filter.

粉末の飛散の防止が確実となる。Further, since the powdered matcha canned food is filled with nitrogen gas, there is a problem that the powder rises up when opening it if it is opened as it is. According to the present invention, it is possible to prevent the rise of air at the time of opening by venting the gas in the container before opening. In the case of matcha powder, the particles are very fine and there is a concern that the opening of the degassing score may cause a rise in air, so it is preferable to attach a filter such as nylon mesh or filter paper to the degassing score. Prevents powder from scattering.

こぼれは防止できる。As described above, according to the invention as set forth in claim 1, since the degassing score is provided on the lid separately from the opening score, and the degassing score is broken on the lower surface of the lifting portion of the tab. Since the protrusion is provided and the lifting portion of the tab is pushed downward before the opening score is broken, the degassing score is broken to lower the internal pressure of the container body, so that even if the opening score is rapidly opened, the contents Can be prevented from blowing. In particular, even if the gas venting score is opened, it is opened while being covered by the protrusion of the tab, so that the gap formed in the opening is extremely narrow, and even if the gas escapes, the contents can be prevented from spilling.

Can be prevented. The container according to claim 3 is
Since the container body, in which the contents whose inside is positively pressurized is stored, is sealed by the blowout preventing easy opening lid of the present invention, a container without blowout can be realized.
