Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a synthetic resin hinge cap to be fitted to the mouth of a liquid container made of synthetic resin or glass.

[0002]

[Prior art]

 6 and 7 relate to a conventional stopper-type synthetic resin cap disclosed in, for example, Utility Model Registration No. 2578042. This is pressed into contact with a top lid p and an inner lid b having a cylindrical portion covering the outer periphery of the mouth of the container, and an engaging recess i formed on the outer periphery of the container mouth formed inside the cylindrical portion. An engaging projection h to be engaged, an outer lid c integrally provided on the inner lid b via a three-point snap hinge d, and a part of the top wall p and corresponding to the hinge d A weakening line q formed in a portion to be formed, a weakening line r formed on one side of the hinge d from the upper end to the lower end of the cylindrical portion and continuous with the weakening line q, and a lower portion of the hinge d. And a cylindrical portion f, which is formed to be continuous with the cylindrical portion f corresponding to the other end of the weakening line r, and which is pulled cantilever outward when the outer lid c is pulled outward. The three-point snap hinge d is located at a center spring hinge do and on both sides thereof, and is a pivot point. And a pair of thin hinges dn.

The above-mentioned synthetic resin cap can pull the pull tab 1, cut out the shielding wall j and pull it out, and pour the contents from the injection pipe m. When the container is collected and reused after use of the internal articles of the container, when the outer lid c is gripped and pulled outward, the weakening formed on the top wall p via the hinge d is performed. Line q and weakening line r are torn off. Still further, when the outer lid c is pulled outward, the force is exerted on the pulling portion below the hinge. Therefore, the vicinity of the traction portion is deformed outward, and the engagement is loosened. In this state, when the outer lid c is pulled obliquely upward, the engagement between the cylindrical portion f below the hinge d and the cylindrical portion adjacent to the traction portion connected thereto is loosened, and the cylindrical portion f is lifted upward. The cap can be removed with a bare hand without using a bottle opener.

[Problems to be solved by the invention]

 Since the hinge of the synthetic resin cap as described above is generally oriented in the bending direction, it is extremely strong against the repeated bending stress generated when the outer lid is opened and closed, but weak against the force in the tearing direction. When collecting and pulling the outer lid during collection, if the tear resistance of the fitting part of the inner lid is too large, the hinge may break, making it difficult to separate and collect.

The present invention has been made in order to solve these problems, and it is easy to tear with the help of a holding piece at the time of sorting and collecting, and therefore, the hinge does not break. An object of the present invention is to provide a hinge cap that can be easily collected.

[0006]

[Means for Solving the Problems]

 The present invention has been made to achieve the above object, and the hinge cap which can be easily separated and collected according to claim 1 is a fitting ridge which is engaged with a constricted concave portion 2a on an outer periphery of a mouth portion 2 protruding from a container 1. An inner lid 7 provided with an outer peripheral wall 3 having an outer ring 3a, an upper fitting wall 4, and a fitting portion 6 composed of an inner ring 5, and an outer lid 9 integrally connected to the inner lid 7 via a hinge 8. In the provided synthetic resin hinge cap 10, a gripping piece 11 protruding outward from the vicinity of the side of the hinge attachment position 3 b of the outer peripheral wall 3 is formed in a state curved to the opposite side to the hinge 8. A longitudinal weakening line 12 is formed on the outer peripheral wall 3 along a position adjacent to the hinge 8 at the base position of the holding piece 11, and the weakening line 12 is formed continuously above the weakening line 12. In the circumferential direction along the inside of the hinge mounting position 3b The formation line 13 is formed on the fitting upper wall 4.
