Description

Cap opener

The present invention relates to a cap opener for removing a screw lid attached to a mouth portion of a container and a ring attached to the screw lid to prevent manual opening of the screw lid.

As such a cap opener, a structure disclosed in the following Patent Document 1 is known. The container opened by the cap opener is roasted coffee beans, and such coffee beans have a property of releasing carbon dioxide gas. Therefore, when the roasted coffee beans are filled in the storage container, the internal pressure is increased by the carbon dioxide gas. Therefore, the mouth of the container is firmly tightened by the screw lid in order to improve the sealing performance. In order for the user to loosen the screw cap manually, considerable gripping power and arm strength are required. Therefore, the screw lid is opened using a cap opener which is a dedicated jig. This cap opener has a needle portion, and the needle portion is stabbed before the lid is opened to release the internal pressure.

As mentioned above, the screw cap is firmly tightened and is opened by a dedicated cap opener. However, if there is arm strength, the user can also open it manually. If it does so, a screw lid will be opened in the state whose internal pressure is higher than external pressure, and the problem that the contents will eject will arise. Therefore, in Patent Document 1 below, a ring is attached around the screw lid so that it cannot be manually opened by mistake. And this ring is also removed using a cap opener.

The method of using the cap opener in Patent Document 1 is generally as follows. The cap opener includes a head that covers a screw lid and a pair of arms. By holding the arm by hand and performing a closing operation, the contact portion of the head is brought into pressure contact with the screw lid. Thereafter, the screw lid is removed from the mouth portion of the container by rotating the cap opener. At this time, the ring remains attached to the mouth. Therefore, the cap opener is attached again to the mouth portion of the container, and the locking portion provided on the head is operated to lock the locking portion to the ring so that the ring is removed from the mouth portion.

Two engaging portions 8 are integrally formed on the back side of the frame portion 1. The engaging portion 8 has an engaging claw 80 and can enter the lower portion of the flange portion A12 of the ring A. By closing the pair of arms B2, the pair of engaging portions 8 are also moved inward and enter the lower portion of the flange portion A12 of the ring A.

<How to use the cap opener>
Next, a method for using the cap opener according to the present invention will be described. When the user of the cap opener B (see FIG. 1 and the like) removes the screw lid C2, first, the head B1 is placed on the ring A and the screw lid C2, as shown in FIG.

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 abutting 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 lid C2, and the lateral movement of the head B1 is restricted. In this case, the needle portion 6 is covered with the needle cover 4. Moreover, the contact part 2 is in a state where it has entered partway through the space V3. Of the three guide portions A2 of the ring A, the upper ends of the two guide portions A2 are in a state of entering the guide grooves 10 formed in the head B1. The upper end portion of the remaining one guide portion A2 enters the space V2 in the open portion of the frame portion 1 formed in a C shape.

Subsequently, the user applies 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 penetrates the top surface portion C21, and the head B1 moves downward. When the user moves the head B1 downward, the contact portion 2 enters a state between the guide portion A2 and the screw lid C2, and the guide portion A2 is a state in which most of the guide portion A2 enters the guide groove 10. It becomes. At this time, the needle cover 4 moves upward against the urging force of the needle cover return spring 5 and is accommodated on the inner diameter side of the cylindrical portion 33.

When the needle part 6 penetrates the top surface part C21, the gas in the container C1 is released to the outside through the inside of the needle part 6 and the second through hole 71, and the internal pressure of the container C1 decreases.

When the internal pressure of the container C1 is released, the user grips and tightens the pair of arms B2 shown in FIG. 1 to reduce the diameter of the frame 1 (arrow D). When the diameter of the frame part 1 is reduced by the gripping force of the user, the diameter of the contact part 2 is reduced in conjunction with the diameter reduction of the frame part 1, and the surface of the anti-slip rubber 20 of the contact part 2 as shown in FIG. Comes into pressure contact with the peripheral surface portion C22 of the screw lid C2.

Also, the diameter of the frame portion 1 provided with the engaging portion 8 is reduced (arrow E in FIG. 11). Accordingly, the engaging claw 80 of the engaging portion 8 approaches the circumferential portion A11 of the ring A and further enters the lower side of the flange A12.

Thereafter, the user turns the pair of arms B2 around the screw lid C2 while maintaining the state in which the contact portion 2 is in pressure contact with the peripheral surface portion C22, and the rotational torque is applied to the screw lid C2 via the contact portion 2. Is granted. In addition, when maintaining the state which the contact part 2 pressed against the surrounding surface part C22, a user continues and clamps a pair of arm B2 shown in FIG. Alternatively, the use of a lock member (not shown) that locks the pair of arms B2 close to each other improves the operability.

When a rotational torque of a predetermined value or more is applied to the screw lid C2, the screw lid C2 is loosened, so that the user can easily remove the screw lid C2 from the container C1, as shown in FIG. . Further, since the rotation torque is applied in a state where the engagement claw 80 engages the ring A, the ring A can be removed together with the screw cover C2. Therefore, it is convenient that the screw cap C2 and the ring A can be removed simultaneously by one operation.

<Another embodiment>
Although the configuration in which the anti-slip rubber 20 is provided as the configuration of the contact portion 2 has been described, the anti-slip rubber 20 is not necessarily provided. In addition to providing the non-slip rubber 20, the surface may be uneven, or a non-slip surface treatment may be performed.

In the present embodiment, the configuration in which the contact portion 2 is in pressure contact with the screw lid C2 has been described, but an engaging configuration may be employed. For example, an engagement portion that engages with the unevenness of the thread formed on the peripheral surface portion C22 can be formed on the contact portion 2.
