摘要： PROBLEM TO BE SOLVED: To prevent a trouble like an erroneous rupture of score by an ordinary user from occurring with no score-rupturing tab provided at the external face of a cylindrical side wall, and to make a cap easily removable by hand from a mouth part of a container without using a special tool. SOLUTION: The present cap is composed of a cap main body 1 to be fitted and fixed to a mouth part of a container and an upper lid 2 to be provided for covering the cap main body 1, and the cap main body 1 is constructed, being equipped with a top plate part 5 whereon a contents-pouring opening can be formed and a cylindrical side wall 6 extending from the peripheral edge of the top plate part 5. A protuberance 20 for engagement with the external face of the mouth part of the container is formed at the inner face of the cylindrical side wall 6 while an annular score 30 is formed on a position at the underside of the protuberance 20, and the lower end of the cylindrical side wall 6 is curved toward the inside so that it can be fitted into a groove formed at the external face of the mouth part of the container. A slit 31, being a starting point for rupture for the annular score 30, is extending upward from the lower end of the cylindrical side wall 6 up to a point not reaching to the annular score 30.

摘要： PROBLEM TO BE SOLVED: To provide a container lid made of synthetic resin in a form that a reinforcing wall surrounding a vertical wall of a lid body is placed wherein the vertical wall and the reinforcing wall surrounding it are integrally manufactured simply by injection molding or compression molding, and when a lid body is to be removed from a neck of a container, reinforcement of the vertical wall can be canceled. SOLUTION: The container lid made of synthetic resin attached to a neck of a container equipped with a locking jaw on an outer peripheral face includes a lid body 4 having a cylindrical vertical wall 42 including a locking protrusion 421 to be locked with the locking jaw on an inner peripheral face and a cylindrical reinforcing wall 42 surrounding the vertical wall 42. The reinforcing wall 43 is connected to the vertical wall 42 at a position corresponding to the locking protrusion 421 via a narrow connection 47 as wide as 0.2 to 0.8 mm. The reinforcing wall 43 is formed with a plurality of breaking lines 432 extending from an upper end of the wall to at least a position corresponding to the locking protrusion 421.

摘要： PROBLEM TO BE SOLVED: To release the reinforcing action of a vertically hung wall by a method wherein a cylindrical reinforcing wall which surrounds the vertically hung wall is connected to the vertically hung wall with a narrower width connecting part of a specified width, and a major breaking line which extends to the connecting part is formed on the reinforcing wall, and the narrower width connecting part is made to be an easily breakable thinner region. SOLUTION: A cylindrical reinforcing wall 43 is arranged in a manner to surround a cylindrical vertically hung wall 42, and a male thread 431 is formed on the outer periphery. For the cylindrical reinforcing wall 43, the lower end is connected to the lower end of the cylindrical vertically hung wall 42 with a narrower width connecting part 47. The width S of the narrower width connecting part 47 is set to be 0.2-0.8 mm. For the cylindrical reinforcing wall 43, a major breaking line which extends from the upper end to the narrower width connecting part 47 is formed at a location being adjacent to a non- breakable thick region of a thinner easily breakable region. By this method, a lid main body 4 can be easily removed from the mouth part of a container.

摘要： PURPOSE: To keep a bridging part unbroken, which is provided on a peripheral weak line formed on a skirt wall of a cover, when the cover is fitted to a mouth-neck part of a container and to easily and surely break it when the mouth-neck part of the container is opened. CONSTITUTION: A ratchet claw projected upward is formed on a mouth-neck part of a container. A plurality of projected pieces 42 are formed on an inner peripheral surface of a skirt wall of a cover so as to be spaced at intervals in a peripheral direction. A part of the projected piece 42 forms a bridging part 54. A peripheral weak line 28 is formed by cutting the skirt wall. The lower part of the projected piece 42 forms a ratchet piece 50 operated in conjunction with the ratchet claw.

摘要： PROBLEM TO BE SOLVED: To provide a hinge cap with a sorting function which can be easily separated from a container mouth part without using any tool, ensure the sufficient liquid-tightness, and can be fitted to the container without breakage due to pressure when capping. SOLUTION: The hinge cap with the sorting function has a cap body and an upper lid capable of being connected with each other via a hinge in an openable and closable manner, and a longitudinally weakened portion formed in a part close to the hinge of a skirt wall of the cap body and a circumferential weakened portion for separating the skirt wall and a top plate is formed on a circumferential edge part of the top plate. A plurality of ribs extending up and down are provided on a sidewall-inner-circumference surface of the upper lid at intervals in a peripheral direction so as to abut on an upper surface of an external wall located on the circumferential weakened portion when the upper lid is closed.

摘要： PROBLEM TO BE SOLVED: To provide a plastic cap configured so that an engagement projection of a cap body can slide over an engagement part of a container mouth part smoothly, a decrease or the like in fitting force of an upper lid which results from capping is effectively prevented, and categorized disposability is excellent. SOLUTION: A thin-wall breakable line 13 is formed in a cap body skirt part below the engagement projection 11 of skirt parts 3a and 3b so as to extend in a peripheral direction and so as to be torn. The plastic cap can be easily detached from the container mouth part 50 after exhaustion of the content, by tearing off the breakable line 13. On the internal face of the skirt parts are: a plurality of upper ribs 12, each of which is formed below the engagement projection and has a tapering internal face whose inside diameter increases toward a lower side; and a plurality of lower ribs 14, each of which is formed below the breakable line and has a tapered internal face whose inside diameter increases toward a lower side. The plurality of upper ribs and the plurality of lower ribs are formed so as to be displaced from each other in the peripheral direction. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To effectively restrain breakage and deformation from occurring to a die tool in slit forming at molding and to improve moldability for a composite container cap having a cap main body in a double wall structure wherein at least a part of a cylindrical side wall is divided into an inner side wall and an outer side wall. SOLUTION: For the composite container cap having the cap main body in a double wall structure wherein the cylindrical side wall is divided into the outer side wall and the inner side wall, a corrugated surface having projections and dents alternately in the circumferential direction is formed either at the inside of the outer side wall or the outside of the inner side wall, and thereby the strength of the slit forming die tool is heightened and the pressure of resin applied to the die tool at the time of molding can be dispersed and moldability can be improved with breakage and deformation occurring to the die tool at the time of molding effectively restrained.
