2. Description of the Related Art When a container filled with contents such as sauce is tilted and the contents are discharged, a part of the contents may adhere to and remain on the upper surface of the cap body. May be splashed by the impact of the top cover and stain the surrounding area. Therefore, in order to solve this problem, the following cap has been conventionally used (Japanese Patent Laid-Open No. 8-19829).
(See Japanese Patent No. 7). That is, it is composed of a cap main body attached to the container mouth and an upper lid hingedly connected to the cap main body so as to be rotatable. The cap main body hangs down from a ceiling wall and a peripheral portion of the ceiling wall. The upper surface of the ceiling wall is formed with a circumferential projection of a liquid pouring guide whose upper end is expanded outward, and the circumferential wall is partitioned by the circumferential projection. Is provided with a score capable of forming a liquid pouring opening and a tear tab for tearing the score to form a liquid pouring opening, and the upper lid is
A container lid, which comprises a top surface and a skirt wall hanging down from the peripheral edge of the top surface, and is hinge-connected to the peripheral edge portion of the ceiling wall at the lower end portion of the skirt wall. A ring-shaped projection is formed in a portion between and, and a circumferential recess including a horizontal plane and a circumferential vertical plane continuous with the horizontal plane is formed on the inner surface of the skirt wall of the upper lid, and the circumferential vertical is formed. The surface is formed with an engagement protrusion capable of engaging with the annular convex portion, and the engagement protrusion provided on the circumferential vertical surface and the annular convex portion are engaged with each other when the upper lid is closed. Then, the upper lid is held by the cap body, the horizontal surface of the circumferential concave portion and the upper end of the annular convex portion contact each other, and the lower end surface of the skirt wall of the upper lid extends over at least a half circumferential portion opposite to the hinge connecting portion to the cap main body. Is kept in non-contact state Container closure characterized in that it is.

[0003]

The conventional cap has the following problems. (1) Since the annular convex portion is located inside the outer peripheral edge portion of the upper surface of the cap body, the liquid material leaked during pouring adheres to the horizontal plane portion between the outer peripheral edge portion of the upper surface and the annular convex portion, May remain. Therefore, when the container is tilted, the adhered and remaining liquid substance may flow down along the outer peripheral surface of the cap body.

(2) Since the outer diameter of the cap main body is larger than the outer diameter of the upper lid, it is difficult for the finger to be hung on if the amount of protrusion of the tab of the upper lid is small. Therefore, it is necessary to increase the amount of protrusion of the tabs, but if it is too large, the tabs will be caught by each other when the caps are transported or aligned, which hinders smooth work.

In view of the above circumstances, an object of the present invention is to prevent the liquid matter from scattering when the lid is closed. The other purpose is
This is to prevent the liquid attached to and remaining on the upper surface of the cap body from flowing down along the outer peripheral surface of the cap body.
Yet another purpose is to keep the tabs out of the way.

Therefore, even if the protruding outer peripheral surface portion is present on the lower end surface of the side wall of the upper lid, the liquid material is not scattered. Furthermore, since the projecting outer peripheral surface portion projects to the outside of the cap body, the projecting outer peripheral surface portion can also be used as a part of the knob. Therefore, the amount of protrusion of the tab can be reduced as compared with the conventional example.

According to the present invention, the upper portion of the cap body, which is hinge-coupled to the upper lid, is cut out at a portion opposite to the hinge to form a contact-preventing gap groove, and when the lid is closed, the lower end surface of the side wall of the upper lid is closed. The vicinity of the tab is located on the contact prevention void groove. In this invention, since the lower end surface near the knob does not contact the upper surface, the problem of liquid splash does not occur.
