The present invention relates to a screw cap mounted on an inlet portion of a container and a cap opener for attaching to the screw cap and separating the ring preventing the opening of the screw cap manually.

As such a cap opener, a structure disclosed in Patent Document 1 below is known. The container opened with the cap opener is a coffee bean that has been roasted, and such a coffee bean has a property of emitting carbon dioxide gas. Therefore, when the roasted coffee beans are filled in a container for storage, the internal pressure is increased by carbon dioxide gas. Therefore, the inlet of the container is firmly fixed by the screw cap to increase the tightness. This screw cap requires considerable grip and force to be manually released by the user. Therefore, the cap lid is opened by using a cap opener which is a dedicated tool. The cap opener has a needle portion, and the cap is pierced to open the internal pressure before opening the cap.

As described above, the screw lid is firmly fixed, and it is possible to open it by a dedicated cap opener, or to manually open the user if there is a force. Then, the screw lid is opened with the internal pressure higher than the external pressure, so that the contents are ejected. Thus, in the following Patent Document 1, a ring is attached around the screw cap so that it is not accidentally opened manually. The ring is also separated using a cap opener.

In Patent Document 1, a method of using the cap opener is generally as follows. The cap opener is provided with a head covering the screw cap and a pair of arms. By holding this arm by hand and closing it, the contact part of the head is pressed against the screw cap. Thereafter, the screw cap is separated from the inlet portion of the container by rotating the cap opener. At this time, the ring remains attached to the inlet portion. Here, the cap opener is mounted again on the inlet of the container, and the locking portion provided on the head is operated to lock the locking portion to the ring, thereby separating the ring from the opening.

<Usage of Cap Opener>

Next, a method of using the cap opener according to the present invention will be described. When the user of the cap opener B (see Fig. 1, etc.) separates the screw cap C2, the head B1 is first mounted on the ring A and the screw cap C2 .

Next, as shown in Fig. 10, the lower end portion of the contact portion 2 is inserted into the space V3 between the guide portion A2 and the cap C2. When the contact portion 2 enters the space V3, the tip end portion 60 of the needle portion 6 is positioned at the substantially central portion of the screw cap C2 and the state in which the lateral movement of the head B1 is restricted do. The contact portion 2 is covered with the needle portion 6 and the needle cover 4. The contact portion 2 is in the middle of the space V3. The upper ends of the two guide portions A2 of the three guide portions A2 of the ring A are in the state of being inserted into the guide grooves 10 formed in the head B1. And the upper end of the remaining one guide portion A2 enters the space V2 in the open portion of the C-shaped frame portion 1. [

Then, the user adds a downward force to the head B1. When the user applies a downward force to the head B1, as shown in Fig. 11, the distal end portion 60 of the needle portion 6 passes through the front portion C21 and the head B1 moves downward do. When the user moves the head B1 downward, the abutment portion 2 enters between the guide portion A2 and the screw cap C2, and most of the guide portion A2 is guided by the guide groove A2 10). At this time, the needle cover 4 moves upward against the force of the needle cover return spring 5, and is housed in the inner diameter side of the cylindrical portion 33.

When the needle portion 6 penetrates the front portion C21, the gas in the container C1 is discharged to the outside through the inside of the needle portion 6 and the second through hole 71, and the internal pressure of the container C1 is reduced do.

When the internal pressure of the container C1 is released, the user grasps the pair of arms B2 shown in Fig. 1 to bring them close to each other and contracts the frame 1 (arrow D). When the frame portion 1 is contracted by the user's gripping force, the contact portion 2 shrinks in conjunction with the contraction of the frame portion 1, and as shown in Fig. 11, the contact portion 2 of the non-slip rubber 20 And the surface thereof is brought into pressure contact with the main surface portion C22 of the screw cap C2.

Also, the frame portion 1 provided with the engaging portion 8 contracts (arrow E in Fig. 11). The engaging projection 80 of the engaging portion 8 is closer to the circumferential portion A11 of the ring A and further enters the lower side of the flange A12.

The user then rotates the pair of arms B2 around the screw cap C2 while keeping the contact portion 2 in contact with the main surface portion C22, To the screw cap C2. In addition, when the contact portion 2 is held in pressure contact with the main surface portion C22, the user continues to tightly grip the pair of arms B2 shown in Fig. Alternatively, use of a lock member (not shown) for locking the pair of arms B2 in a state of being close to each other improves operability.

The tightening of the screw cap C2 is loosened if a rotational torque of a predetermined value or more is applied to the screw cap C2 so that the user can easily remove the screw cap C2 from the container C1 Can be separated. Since the engaging projection 80 is provided with a rotating torque in a state in which the ring A is engaged, the ring A can be separated together with the screw cap C2. Therefore, it is convenient to separate the screw cap (C2) and the ring (A) at the same time by one operation.
