[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a pill fur proof cap (hereinafter, abbreviated as cap) having a pill fur proof ring for confirming whether a container is unopened or unopened.

[0002]

[Prior Art]

 FIG. 2 shows a cap disclosed in JP-A-63-96052 as a conventional example of this type of cap. This cap has a disc-shaped top plate 1 and a cap body 3 having a skirt portion 2 suspended from the peripheral edge thereof, and a pill fur proof ring 5 connected to the skirt portion 2 by a bridge 4, and the pill fur proof ring is provided. A plurality of wings 6 extending inward are formed on the inner peripheral wall surface of the ring 5.

Each of these wings 6 is elastically movable outwardly from the container about the hinge means inclined at an acute angle with respect to the axis of the cap when the cap is attached to the container 7. The part of the container 6 which is constructed and which is engageable with the locking ring 8 provided on the container 7 for breaking the bridge 4 and underneath the locking ring 8 and close to the locking ring 8. It is sized and dimensioned to engage with. Although each wing 6 is flexible, as shown in FIG. 3, the abutment edge portion 9 engaging the locking ring 8 exerts a pressure on the wing 6 around the edge portion 10. When the locking edge portion 11 is broken, the locking edge portion 11 is made to have a sufficiently large elasticity and a thickness that can surely prevent the locking edge portion 11 from passing through the container opening portion 12.

When the cap body 3 is rotated in the opening direction after it is attached to the container, the cap body 3 moves upward along the thread, but the pill fur proof ring 5 is locked by each wing 6. When the pill fur proof ring 5 is abutted against the ring 8 and bent to prevent the pill fur proof ring 5 from moving upward, a tensile force acts between the cap body 3 and the pill fur proof ring 5, and this force causes the cap body 3 and the pill to move. The bridge 4 connecting the fur proof ring 5 is cut and the pill fur proof ring 5 is cut off from the cap. Thus, even if someone opens the cap attached to the container and then closes it again, the opening action becomes clear by cutting the pill fur proof ring 5, preventing mischief such as foreign matter entering the container. Has the effect of

[0005]

[Problems to be solved by the device]

 However, since the conventional cap is made of synthetic resin, when the cap is opened, each wing 6 comes into contact with the locking ring 8 of the container to bend, and the bridge 4 is subjected to a tensile force or the like. However, since it is elastically deformed to some extent and is not cut immediately, the cap rotation angle required to turn this cap in the opening direction and cut the bridge is about twice that of the aluminum pill fur proof cap. Will be needed. Further, even when compared with the rotation angle at which the hermeticity of the container is impaired, the synthetic resin cap is about twice as large. As described above, in the conventional cap, the pill fur proof ring cannot be reliably cut unless the cap is rotated about 360 degrees in the opening direction, and thus the effect of preventing mischief is poor.

The present invention has been made in view of the above circumstances, and in a pill fur proof cap made of synthetic resin with a wing, the pill fur proof ring can be reliably cut even at a small rotation angle to prevent mischief. The aim is to provide caps that are more effective.

[0007]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the pill fur proof cap of the present invention has a screw portion formed on an upper portion thereof, and a pill fur proof ring locking bulging portion bulges outward under the screw portion. A pilfer roof cap used to close the mouth of the container body, the cap body having a top plate and a skirt portion hanging down from the periphery thereof, and a pilfer provided below the cap body. The pill fur proof ring and a bridge connecting the pill fur proof ring and the cap body are provided, and the inner peripheral wall surface of the pill fur proof ring has a container body opening portion when the cap is lifted when opened. Plural inwardly extending wings to lock the pill fur proof ring into the locking bulge and prevent the pill fur proof ring from rising. In the pill fur proof cap made of synthetic resin, the screw formed on the cap body to attach this cap to the mouth of the container is a multiple thread, and their phase is 360 degrees in terms of the number of threads. This is a configuration in which the angle is shifted by dividing.

[0008]

[Action]

 In the pill fur proof cap of the present invention, the multiple thread is formed in a predetermined phase on the cap body. When the multi-thread screw is formed in this way, the tilt of the cap body is restricted by each screw thread. As a result, when the cap body is rotated in the reverse screw direction for opening, the cap body rises vertically without tilting along the axis of the container mouth. Therefore, the pill fur proof ring connected to the lower end of the cap body also vertically rises along the axis of the container opening. As a result, the probability that each wing of the pill fur proof ring will simultaneously come into contact with the bulging portion for locking the pill fur proof ring at the container mouth portion is further increased. In addition, the pill fur proof cap of the present invention is provided with a multi-start screw, so the pitch of the screw can be increased while preventing the cap from tilting at the time of opening and without impairing the cap opening force of the cap. This makes it possible to increase the vertical displacement of the cap with respect to the rotation amount of the cap.

[0009]

【Example】

 Hereinafter, the pill fur proof cap of the present invention will be described with reference to the drawings. FIG. 1 shows an example of a cap of the present invention, and the same components as those shown in FIGS. 2 and 3 are designated by the same reference numerals. The cap of this example includes a cap body 3 having a disc-shaped top plate 1 and a skirt portion 2 hanging down from the periphery thereof, and a pill fur proof ring 5 (hereinafter, referred to as PP) provided below the cap body 3. And a bridge 4 that connects the PP ring 5 and the cap body 3 as main components.

This cap is made of synthetic resin, and a multiple thread 13 is formed on the inner surface of the skirt portion 2 of the cap body 3. The multi-thread screw 13 has two or more threads, and in the cap of this example, two threads 13a and 13b are provided (the two-dot chain line in FIG. 1 indicates Shows the thread on the front side of the cross section).

Further, this cap is provided on the inner peripheral wall surface of the PP ring 5 with a locking ring 8 for locking the PP ring provided below the thread of the mouth of the container 7 when the cap is lifted when opened. A plurality of inwardly extending wings 6 are formed to lock and prevent the PP ring 5 from rising.

Such a cap is used by being attached to a container having a multi-threaded screw formed at the container opening. Then, when this cap is rotated for opening, the threads 13a and 13b of the multi-thread screw 13 formed on the skirt portion 2 of the cap are positioned at 180 degrees relative to each other (120 degrees position for three-thread thread). Since it engages with the threads of the container mouth, this limits the tilt of the cap and causes the cap to rise straight along the axis of the container mouth. As a result, there is an increased possibility that all the wings 6 of the PP ring 5 of the cap will simultaneously come into contact with the locking ring 8 of the container mouth. Each wing 6 is flexible, but as shown in FIG. 3, when the wing 6 is pressed around the edge portion 10 by the abutting edge portion 9 engaging the locking ring 8, Since the locking edge portion 11 is made to have a sufficiently large elasticity and thickness so as to surely prevent the locking edge portion 11 from being broken and passing through the container mouth portion 12, the PP ring 5 is locked. It does not come out beyond the ring 8. Therefore, when the cap is further rotated, the bridge 4 is cut while the PP ring 5 is still securely locked to the locking ring 8, and the opening can be opened more smoothly.

Further, in the cap of this example, since the multi-thread screw 13 is provided, the pitch of the screw can be prevented while preventing the cap inclination at the time of opening the cap and without impairing the cap opening force. Can be large. Thus, the vertical displacement of the cap with respect to the rotation amount of the cap can be significantly increased. This cap therefore allows the wings 6 to flex like a cap that engages the wings 6 on the PP ring with the locking ring 8 of the container to prevent upward movement of the PP ring 5. Even with a cap that cannot cut the bridge 4 unless the cap rotation amount is increased, the bridge 4 that connects the cap body 3 and the PP ring 5 can be reliably cut with a small amount of rotation. Since the bridge 4 that connects the cap body 3 and the PP ring 5 can be surely cut with less rotation, it is possible to surely identify what has been opened once and improve the effect of preventing mischief.

[0014]

[Effect of the device]

 As described above, the pill fur proof cap of the present invention is a cap in which a plurality of wings extending inward are provided on the inner peripheral wall surface of the PP ring, and the multi-thread screw has the phase in the number of threads. It is provided with an angle offset of 360 degrees. In the cap of the present invention having such a structure, since the tilt is prevented by the multiple thread, the cap rises vertically without tilting along the axial line of the container opening portion and is connected to the lower end of the cap body. The pill fur proof ring also rises vertically along the axis of the container mouth. As a result, each wing of the pill fur proof ring has a higher probability of simultaneously contacting the bulged portion of the pill fur proof ring at the container mouth.

Further, in the cap of the present invention, since the multiple thread is provided, the pitch of the screw is increased while preventing the cap inclination when opening the cap and without impairing the cap opening force. be able to. As a result, the vertical displacement of the cap with respect to the rotation amount of the cap can be significantly increased. Therefore, according to this cap, like the cap that prevents the PP ring from moving upward by engaging the plurality of wings provided on the PP ring with the pilfer proofing bulging portion of the container mouth, Even if the cap cannot be cut unless the cap rotation amount is increased due to the bending of the cap, the bridge connecting the cap body and the PP ring can be reliably cut with a small rotation.

Further, since the bridge connecting the cap body and the PP ring can be surely cut with a small number of rotations, it is possible to surely identify what has been once opened and improve the effect of preventing mischief. ..
