Opener

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

As the cap opener, a structure disclosed in Patent Document 1 below is known. The container opened with the lid opener is a roasted coffee bean having the property of releasing carbonic acid gas. Therefore, when the container for the roasted coffee beans is stored, the internal pressure is increased by the carbonic acid gas. Therefore, in order to improve the sealing property, the mouth of the container is strongly tightly covered with a screw cap. If the user wants to manually loosen the screw cap, it requires considerable grip and wrist force. In response to the above problem, the screw cap is opened using a cap opener equivalent to a dedicated jig. The cap opener has a needle portion that pierces the needle to release the internal pressure before opening the cap.

As mentioned above, the screw cap is strongly capped and is opened by a dedicated cap opener, but the user may open it manually as long as there is sufficient wrist force. As a result, the screw cap is opened in a state where the internal pressure is higher than the external air pressure, and the content is ejected. In response to the above problems, in the following In Patent Document 1, an annular portion is attached around the screw cover so as not to be manually opened. Moreover, the annular portion is also removed using a cap opener.

The method of using the cap opener in Patent Document 1 is roughly as follows. The cap opener has a head that covers the screw cap and a pair of arms. The abutment portion of the head is crimped to the screw cap by holding the arm portion in a hand-held and closing operation. Thereafter, the screw cap is detached from the mouth of the container by rotating the cap opener. At this time, the annular portion is still installed in the mouth portion. Therefore, the cap opener is again attached to the mouth of the container, and the locking portion provided on the head is operated to lock the locking portion to the annular portion, and the annular portion is removed from the mouth portion.

When the user applies a downward force to the head B1, as shown in FIG. 11, the front end portion 60 of the needle portion 6 penetrates the top surface portion C21, and the head portion B1 moves downward. When the user moves the head B1 downward, the abutting portion 2 enters between the guiding portion A2 and the screw cap C2, and the guiding portion A2 enters the guiding groove 10 as a majority. At this time, the needle cover portion 4 moves upward against the elastic pressure of the needle cover portion return spring 5, and is accommodated in the inner diameter side of the cylindrical portion 33.

After the needle portion 6 penetrates the top surface 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.

After the internal pressure of the container C1 is released, the user grips one of the arms B2 as shown in FIG. 1 to bring the two closer together, and the frame portion 1 is reduced in diameter (arrow D). After the frame portion 1 is reduced in diameter by the grip strength of the user, the abutting portion 2 is reduced in diameter by the reduced diameter of the frame portion 1, and as shown in FIG. 12, the surface of the anti-slip rubber 20 of the abutting portion 2 is crimped to The peripheral surface C22 of the screw cap C2.

Further, the frame portion 1 provided with the engaging portion 8 is also reduced in diameter (arrow E in Fig. 12). Therefore, the engaging claw 80 of the engaging portion 8 approaches the cylindrical portion A11 of the annular portion A and further enters the lower side of the flange portion A12.

Then, while maintaining the state in which the contact portion 2 is pressed against the circumferential surface portion C22, the user rotates the pair of arm portions B2 around the screw cap C2, and transmits the rotational moment to the screw cap C2 through the abutting portion 2. Further, when the contact portion 2 is pressed against the circumferential surface portion C22, the user continues to grip the arm portion B2 as shown in FIG. Alternatively, as long as a locking member (not shown) that locks the pair of arm portions B2 in the approaching state is used, the operability is further improved.

After the screw cap C2 is given a rotational torque of a predetermined value or more, the cover of the screw cap C2 is tightly slackened, so that the screw cap C2 can be easily removed from the container C1 by the user as shown in FIG. Further, since the engagement torque is given to the engagement portion 80 in the state in which the annular portion A is locked, the annular portion A can be removed together with the screw cover C2. Therefore, it is convenient to simultaneously remove the screw cap C2 and the annular portion A in one operation.
