DETAILED DESCRIPTION OF THE INVENTION
A first embodiment of the present invention will be described with reference to FIGS.
The cap body 1 is connected to the upper lid 15 via the hinge 10. The cap body 1 includes a top wall 2, an outer cylinder 3 continuous with the top wall 2, and an inner cylinder 4 provided inside the outer cylinder 3.
[0012]
An annular locking portion 5 is provided on the top surface of the top wall 2, and a dispensing cylinder 6 is provided inside the locking portion 5. An excision opening 7 is provided inside the dispensing cylinder 6. The opening 7 is opened by pulling the pull ring 8 and tearing it from the fissure 8a. On the inner surface of the outer cylinder 3, an annular convex portion 9 is provided, which is fitted into an annular concave portion (not shown) of the container mouth portion.
[0013]
The upper lid 15 includes a top plate 16 and a skirt portion 17. An annular seal wall 18 is provided on the inner surface of the top plate 16, and an annular engagement portion 19 that engages with the locking portion 5 is provided on the lower inner surface of the skirt portion 17.
[0014]
The lower end surface of the skirt portion 17 is a joint surface that comes into contact with the outer peripheral portion 2a of the upper surface of the cap body 1, and on the opposite side of the skirt portion 17 from the hinge 10 is a flange portion 20 for hooking a finger. Is provided.
In the vicinity of both sides of the flange 20, prying opening restricting projections 32 are provided. The protruding amount of the protrusion 32 is smaller than that of the flange portion 20.
[0015]
A belt-shaped protective cover 26 is connected to the outer cylinder 3 via a circumferential weakening portion 25, and a pry-off preventing portion 28 is provided at the lower end of the belt-shaped protective cover 26.
The band-shaped protective cover 26 is provided with a storage recess 30 for storing the flange 20. The cover 26 extends in a circular arc shape to the left and right around the storage recess 30 so as to cover the joint surface, but the arrangement length (arrangement angle) is appropriately selected as necessary, For example, an arrangement angle = 200 degrees is selected.
[0016]
Although the bridge 25a and the slit 25b are used as the circumferential direction weakening part 25, the length etc. are suitably selected as needed. For example, the length or thickness of the bridge 25a is made weaker by forming the housing recess 30 side smaller than the other portions.
In addition, the circumferential direction weakening part 25 is not limited to the said bridge | bridging, For example, you may make it a thin part.
[0017]
The prying prevention portion 28 is an arc-shaped plate having a width larger than the width of the storage recess 30, and is continuous to the lower side of the storage recess 30 of the belt-shaped protective cover 26, and its lower end 28 a is the lower end of the cap body 1. It extends to the vicinity of 1a.
[0018]
Next, the operation of the present embodiment will be described.
In the case of normal opening, when the upper lid 15 is opened for the first time, if one end 26a of the band-shaped protective cover 26 is picked with a finger and pulled in the direction of the collar 20, the bridge 25a is cut and the band-shaped protective cover 26 is removed from the cap body 1 And the buttocks 20 are exposed. In this state, the upper lid 15 is opened by placing a finger on the buttocks 20.
[0019]
In the case of unauthorized opening, when a finger is put on the upper end portion of the belt-like protective cover 26 and an attempt is made to pry it open, the peg opening prevention portion 28 is displaced with the circumferential weakening portion 25 as a fulcrum, and the lower end 28a thereof is a one-dot chain line 28 in FIG. As shown, since it is pressed against the lower end 1a of the cap body 1, it can no longer be displaced.
[0020]
Therefore, if the force is further applied in the same direction to open it and try to pinch the collar portion 20, the bridge 25a is cut. Therefore, when the upper lid 15 is opened, the bridge 25a is always cut, so that it is possible to reliably know the illegal opening.
[0021]
A second embodiment of the present invention will be described with reference to FIG.
The difference between this embodiment and the first embodiment is that the longitudinal weakening portion 22 is formed in the belt-shaped protective cover 26. The longitudinal weakening portion 22 is a thin portion in the longitudinal direction provided on both sides of the storage recess 30. The shape, the arrangement position, the number, etc. are appropriately selected as necessary. You may form in the surface side of the protective cover 26. FIG. When the longitudinally weakened portion 22 is provided, the longitudinally weakened portion 22 is cut together with the bridge at the time of unauthorized opening, so that it is more surely understood that the unauthorized opening has been performed.
[0022]
A third embodiment of the present invention will be described with reference to FIGS.
The difference between this embodiment and the first embodiment is that a narrow gap rib 29 is provided on the inner surface of the prying prevention portion 28 to reduce the gap between the cap body 1 and the prying prevention portion 28.
[0023]
A plurality of the ribs 29 are provided along the longitudinal direction of the prying prevention portion 28 and extend to the vicinity of the lower end 1a. Since the gap between the cap main body 1 and the prying opening preventing portion 28 is narrowed by the rib 29 as compared with the first embodiment, the displaceable range of the prying opening preventing portion 28 is narrowed. For this reason, the circumferential weakened portion is cut earlier than in the first embodiment. In addition, the shape, arrangement position, number, etc. of the ribs 29 are appropriately selected as necessary.
[0024]
【The invention's effect】
According to the present invention, since the band-shaped protective cover is provided with the member for preventing the opening of the band, if the band-shaped protective cover is broken open in an attempt to perform the unauthorized opening, the circumferential weakened portion is cut. Therefore, it is possible to know the unauthorized opening with certainty.
