JP 2001-180799 A

  As described above, in the can opening device described in Patent Document 1, when the handle portion is tilted, the entire can lid is detached from the main body of the can. Since the end of the can lid is sharp, there is a risk of injury if the user accidentally touches the end of the can lid when discarding the can lid removed from the main body of the can. That is, when the easy-open can lid is opened with the can opening tool described in Patent Document 1, there is a risk of problems in terms of safety.

  Then, the subject of this form is providing the can opening tool which can open the can lid of an easy open can so that it can handle a can lid safely.

  In order to solve the above-described problems, the can opening device of the present invention includes a handle portion and a pull tab attached to the can lid for opening the can lid of an easy open can in which the entire can lid is removed from the can body. An engaging claw that engages with the pull tab, and when the engaging claw is engaged with the pull tab, the handle is rotated at the initial stage when the can lid is opened by rotating the handle and rotating the handle. From the can body and the curved surface part of the convex curved surface that becomes the fulcrum of movement, and at the final stage when the handle part is rotated to open the can lid, it contacts the upper surface of the can lid and becomes the fulcrum of rotation of the handle part And a detachment preventing portion for preventing the detachment of the can lid.

  The can opening tool of the present invention includes a detachment prevention unit that prevents the detachment of the can lid from the can body. Therefore, even after opening the can lid with this can opening tool, the can lid is still attached to the can body. Therefore, the user can handle the opened can lid by holding the can body without having the can lid. As a result, in the case of an easy open can whose can lid has been opened with the can opening tool of the present invention, it is possible to reduce the risk of the user touching the end of the can lid when processing the can lid. Can be handled safely.

  Further, in the present invention, since the can lid is still attached to the can body even after the can lid is opened, after the contents are taken out from the can body, the direction of rotation of the handle portion when the can lid is opened is reversed. If the handle is rotated, a part or all of the can lid can be pushed into the can body. Therefore, by pushing a part or all of the can lid into the can body, it becomes possible to further reduce the risk of the user touching the end of the can lid when processing the can lid. It can be handled safely.

In the final stage, the upper surface of the can lid can be pressed with a relatively strong force by the disengagement preventing portion. Therefore, it is possible to reliably prevent the can lid from coming off from the can body by the detachment preventing portion.

  In the present invention, the can opening tool includes a detachment prevention member on which a detachment prevention portion is formed, the detachment prevention member is formed in a substantially polygonal flat plate shape, and the detachment prevention portion is a plurality of detachment prevention members formed on the detachment prevention member. It is preferable that it is one of the end surfaces. If comprised in this way, it will become possible to make comparatively wide the contact area of the upper surface of a can lid, and a removal prevention part. Therefore, the upper surface of the can lid can be appropriately pressed by the detachment preventing portion, and the detachment of the can lid from the can body can be reliably prevented.

  In the present invention, the can opening tool includes a detachment preventing member in which a detachment preventing portion is formed, and a convex portion having a convex curved surface that is in contact with the upper surface of the can lid is disposed on the surface of the detachment preventing member. When opening the can lid by rotating the handle portion, the handle contacts the upper surface of the can lid until the detachment prevention portion contacts the upper surface of the can lid after the curved surface portion is separated from the upper surface of the can lid. It is preferable that it becomes the fulcrum of rotation of a part. If comprised in this way, it will become possible to open a can lid easily using the lever principle of turning a handle part by using a curved surface part, a convex part, and a detachment prevention part as a fulcrum one by one. Moreover, it becomes possible to smoothly slide the can opening tool in a state where the engaging claw portion is engaged with the pull tab by using the convex portion on the upper surface of the can lid. Therefore, even when the can lid is large, the can lid can be easily opened while sliding the can opening tool on the upper surface of the can lid.

  In the present invention, the can opening tool includes a curved surface portion forming member in which a curved surface portion is formed. The curved surface portion forming member is formed with a fixing portion to which the detachment preventing member is fixed, and the convex portion is separated from the fixing portion. It is preferable that it is the head of the male screw which fastens the prevention member. In this case, for example, the male screw is a truss screw. If comprised in this way, a convex part can be arrange | positioned on the surface of a fall prevention member using the head part of the external thread which fastens a fixing | fixed part and a fall prevention member. Therefore, compared with the case where a convex part is provided separately from the head of the male screw, the configuration of the can opening tool can be simplified.

  In the present invention, the can opening tool includes a flat plate-shaped disengagement preventing member on which a disengagement preventing portion is formed, the curved surface portion is formed by bending the flat plate member into a substantially semicircular arc shape, The handle portion and the detachment preventing member are disposed substantially in parallel and the curved surface portion is disposed so as to connect the handle portion and the detachment preventing member, and the engaging claw portion is adjacent to the curved surface portion. It is preferable that they are arranged as described above. If comprised in this way, when an engagement nail | claw part is engaged with a pull tab, it becomes possible to arrange | position a can opening tool so that a handle part may stand substantially perpendicularly from the upper surface of a can lid. Therefore, it becomes easy to rotate the handle when opening the can lid. Moreover, if comprised in this way, since the can opening tool is formed in the substantially J shape, it becomes possible to enlarge the rotation amount of the handle part at the time of opening a can lid. Therefore, even if the can opening tool is small, the opening amount of the can lid can be increased.

  As described above, if the can opening tool of the present invention is used, the can lid of the easy open can can be opened so that the can lid can be handled safely.

At this time, the curved surface portion 7 a serves as a fulcrum for the rotation of the handle portion 11. The container 24 is made of glass, plastic or paper.

(Main effects of this form)
As described above, in this embodiment, the can opening tool 1 is formed with the detachment preventing portion 8a that prevents the can lid 2 from coming off from the can body 3, and the detachment preventing portion 8a opens the can lid 2. In contact with the upper surface of the can lid 2 at the final stage. Therefore, even after the can lid 2 is opened with the can opening tool 1, the can lid 2 is stuck to the can body 3. Therefore, even if the user does not have the can lid 2, the user can process the can lid 2 by holding the can body 3. As a result, in this embodiment, it is possible to reduce the possibility that the user touches the end of the can lid 2 when processing the opened can lid 2, and the can lid 2 can be handled safely.

  Further, in this embodiment, since the can lid 2 is still attached to the can body 3 even after the can lid 2 is opened, after the contents are taken out from the can body 3, the arrow V3 in FIGS. If the handle portion 11 is rotated in the direction (that is, if the handle portion 11 is rotated in the upward direction), a part or all of the can lid 2 can be pushed into the can body 3. Therefore, by pushing a part or all of the can lid 2 into the can body 3, it becomes possible to further reduce the risk of the user touching the end of the can lid 2 when processing the can lid 2. The can lid 2 can be handled more safely. Note that the can opening tool 1 can be easily removed from the can lid 2 by rotating the handle portion 11 in the direction of the arrow V <b> 3 in FIGS. 5C and 5B.

  Moreover, in this embodiment, if the can body 3 is held without having the can lid 2, the can lid 2 can be processed, so that the user's hand is hardly soiled. Since the can lid 2 is still attached to the can body 3 even after the can lid 2 is opened, the can body 3 can be lifted and carried together with the can lid 2 using the can opening tool 1.

  In this embodiment, the disengagement prevention portion 8a abuts on the upper surface of the can lid 2 at the final stage when the handle portion 11 is rotated to open the can lid 2, and serves as a pivot point for the rotation of the handle portion 11. Therefore, at the final stage when opening the can lid 2, the upper surface of the can lid 2 can be pressed with a relatively strong force by the detachment preventing portion 8 a. Further, in this embodiment, since one end surface of the third member 8 formed in a substantially square shape is a detachment preventing portion 8a, the contact area between the upper surface of the can lid 2 and the detachment preventing portion 8a is relatively wide. It becomes possible to do. Therefore, it is possible to reliably prevent the can lid 2 from being detached from the can body 3 by the detachment preventing portion 8a.

  In this embodiment, since the curved surface portion 7a contacts the upper surface of the can lid 2 when the engaging claw portion 6a is engaged with the pull tab 5, the curved surface portion 7a is moved after the engaging claw portion 6a is engaged with the pull tab 5. If the handle portion 11 is rotated as a fulcrum, the pull tab 5 can be easily raised with a small force using the principle of the lever. In this embodiment, since the can lid 2 is opened using the lever principle of rotating the handle portion 11 with the curved surface portion 7a, the head portion 12a and the detachment preventing portion 8a as fulcrums, the can The lid 2 can be opened. Therefore, even the elderly person or a handicapped person with a handicapped hand can easily open the can lid 2. In addition, since the can lid 2 can be opened with a small force, the contents are less likely to spill when the can lid 2 is opened. Furthermore, since the pull tab 5 can be easily raised, it is possible to prevent the user's nails from cracking and peeling. Moreover, since the can opening tool 1 of this embodiment is provided with the engaging claw part 6a and the curved surface part 7a, the plastic inner part with the pull tab 22a is utilized by using the engaging claw part 6a and the curved surface part 7a. The lid 22 can be easily opened.

  In this embodiment, the head 12 a having a convex curved surface is disposed on the surface of the third member 8. Therefore, it is possible to smoothly slide the can opening device 1 in a state where the engaging claw portion 6 a is engaged with the pull tab 5 on the upper surface of the can lid 2 using the head portion 12 a. Therefore, for example, even if the shape of the can lid 2 is a substantially elliptical shape or a substantially long shape, the can opening tool 1 in a state where the engaging claw portion 6 a is engaged with the pull tab 5 is slid on the upper surface of the can lid 2. Thus, the can lid 2 can be easily opened. Further, in this embodiment, since the head 12a of the male screw 12 can be used as a fulcrum for turning the handle part 11, the can opener can be opened compared to the case where the fulcrum for turning the handle part 11 is provided separately. The configuration of the tool 1 can be simplified.

  In this embodiment, the can opening tool 1 is formed in a substantially J shape, and the engaging claw portion 6a is disposed adjacent to the curved surface portion 7a. Therefore, when the engaging claw portion 6 a is engaged with the pull tab 5, the handle portion 11 rises substantially vertically above the can lid 2. Therefore, it becomes easy to rotate the handle portion 11 when opening the can lid 2. Moreover, in this form, since the can opening tool 1 is formed in the substantially J shape, it becomes possible to enlarge the rotation amount of the handle part 11 when opening the can lid 2. Therefore, even if the can opening tool 1 is small, the opening amount of the can lid 2 can be increased.

In the present invention, the curved surface portion is formed in a substantially semicircular arc shape, and the can opening tool has a curved surface portion so that the handle portion and the detachment preventing member are arranged substantially in parallel and the handle portion and the detachment preventing member are connected. It is preferable that the engaging claw portion is disposed so as to be adjacent to the curved surface portion. If comprised in this way, when an engagement nail | claw part is engaged with a pull tab, it becomes possible to arrange | position a can opening tool so that a handle part may stand substantially perpendicularly from the upper surface of a can lid. Therefore, it becomes easy to rotate the handle when opening the can lid. Moreover, if comprised in this way, since the can opening tool is formed in the substantially J shape, it becomes possible to enlarge the rotation amount of the handle part at the time of opening a can lid. Therefore, even if the can opening tool is small, the opening amount of the can lid can be increased.
