Description

[Detailed description of the invention] Industrial field of application This invention relates to a cap used at the mouth of a bottle containing various liquid products.

2. Description of the Related Art Conventionally, a cap as shown in FIG. 5a has been used. This is a normal cap, is lightweight, can be completely removed, and is extremely easy to handle, so it is widely used as a replacement lid. b indicates the bottle mouth. A hinge cap c as shown in FIG. 6 is also widely used. In this method, a hinge cap c is opened and closed by a hinge d, and this method is widely used because the cap does not get lost.

Problems that the invention aims to solve: However, some consumers prefer the ease and removability of ordinary caps as shown in Figure 5, while others prefer the ones shown in Figure 6 that do not get lost. However, it is not possible to satisfy both requirements at once.

This invention was made in order to solve the above problems, and the purpose is to allow the user to use it as a hinge cap according to his/her preference, and also to use it as a regular cap as mentioned above. The object of the present invention is to provide a cap that can be easily changed into both of the above types according to the user's preference. Another object is to provide a cap that can prevent unauthorized opening.

Means for Solving the Problems This invention, which achieves the above-mentioned purpose, is described as follows: A cap part 1 made of synthetic resin and a seal part 2 are integrated into one body via a thin fissure 3 formed in the circumferential direction. A pull ring 5 is integrally provided on a part of the outer periphery of the cap part 1 via a bridge part 4 and a tearable piece 9, and the pull ring 5 and the seal part 2 are connected to a part of the outer periphery of the cap part 1. This cap is characterized by being connected in the vertical direction via lobes 10.

Function: The user grasps the portion of the pull ring 5 opposite the bridge portion 4 of the cap fitted on a bottle (not shown) and pulls it upward.

Then, the tear piece 9 is torn, and the tear piece 10 is also torn, and then the fissure groove 3 near the bridging part 4, which is the base of the cap part 1, begins to tear on both sides, and the tear piece 10 also breaks. The cracking progresses gradually, and eventually only a small adhesion part (fissure) remains in the opposite direction of the root. If this happens, stop pulling the pull ring 5,
The slightly remaining fissure 3 is used as a hinge to form a hinge cap.

Also, if a user prefers a normal cap as shown in FIG. 5 above to a hinged cap, the user may further pull the pull ring 5 in the above state and tear the remaining fissure 3 as described above. I'll cut it.

Then, the cap part 1 is separated from the seal part 2, so that the cap part 1 can be used as a normal cap as shown in FIG. 5 mentioned above.

Embodiment In FIGS. 1 to 4, 1 is a synthetic resin cap part, 2 is a seal part, and both 1,
2 are integrally connected via thin fissures 3 formed around the entire circumference.

4 is a bridge-like portion, and 5 is a pull ring. Further, 6 is an inner cylinder, 7 is a protrusion, and 8 is a reversible tongue piece. The pull ring 5 has a split section 9 as shown in FIG.
It is connected to the cap part 1 by.

Further, as shown in FIG. 2, it is connected to the seal portion by a tear piece 10.

Note that 11 indicates a thin groove, and 12 indicates a bottle mouth. When the cap is attached to the bottle spout 12, the tongue piece 8 is turned upward and strongly pressed against the concave portion of the bottle spout 12, thereby creating a strong seal.

It goes without saying that the protrusion 7 also provides a good seal.

Next, as described above, when the pull ring 5 is pinched to tear the fissure 3 near the bridge portion 4, the first tear involves cutting the bridge portion at the diameter of the cap portion relative to the end point of the tear. A moment will be applied to the end of the length of 4. Therefore, tearing can be easily caused with a small force.

And it can be torn apart. Furthermore, by forming the fissures 3 all around the circumference, the cap can be used as a hinge cap or a normal cap by two operations: leaving a small amount of fissures and tearing them all off. There is. Furthermore, since the tongue piece 8 is used as a protrusion by being inverted by the bottle mouth, there is no need to form a protrusion on the inside of the fissure 3 that presses into a concave portion on the outer periphery of the bottle mouth as usual. This also helps in making the fissure 3 easier to tear. Note that the tear piece 9 and the tear piece 10 are designed to be torn very easily.

Effects of the invention This invention is constructed as described above, and the fissure 3 is formed over the entire circumference, and the cap part 1 and the seal part 2 are integrally provided via this fissure 3. It can be used as a hinged cap by leaving a part of it or tearing it off completely, or it can be used as a normal cap as shown in FIG. Also, the cap part 1
A pull ring 5 is attached to a part of the outer periphery of the
By providing this, it is possible to apply a moment to the end of the object with a length from the end of the tear to the bridge-like part 4, so it is possible to start tearing very easily, and also to prevent tearing. The cutting can be progressed and thus hinged caps or regular caps can be formed very easily. In addition, by providing a tear piece 9 that is easy to tear in the radial direction between the pull ring 5 and the cap part 1, and a tear piece 10 that is easy to tear in the vertical direction between the pull ring 5 and the seal part 2, the radius on the outer periphery is It is possible to provide a sealing function not only in the direction but also in the vertical direction, and it is possible to provide a function to prevent unauthorized opening over a wider range.
