Abstract

(57) [Summary] [Purpose] To provide a tab in which a cut lid does not enter the inside of a can container and can be opened with a slight force. [Structure] The tab has a raised portion 6a at one end and an abutting portion 6 at the other end.
b, a bent portion 6d extending in the direction of the abutting portion 6b from the raised portion 6a, and a fixing portion 6e formed at the tip of the bent portion 6d, part of which is wound around the outer peripheral edge of the can container 1. It is fixed at the fixing portion 6e to the lid 4 having the score line 5 engraved on the end panel 2 of the can container 1 in the vicinity of the tightening portion 3 and by bending the bending portion 6d when the raising portion 6a is caused. The contact portion 6b is moved in the direction of the winding portion 3 so that the contact portion 6b contacts the winding portion 3.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a tab for opening a lid formed by engraving score lines on an end panel of a can container.

[0002]

[Prior art]

 The tab, which is currently the mainstream, is designed such that, as shown in, for example, Japanese Utility Model Laid-Open No. 3-111939, at the time of opening the lid, the tip of the cut lid is bent inside the opened opening. ing.

[0003]

[Problems to be solved by the device]

 In the conventional tab, since the tip of the lid is bent inside the opening as described above, the lid is soaked in the contents (liquid such as soft drink or solid contents such as canned contents), and the lid is closed. It was unsanitary because dust and dirt adhering to the outer surface entered the contents.

It is an object of the present invention to provide a tab in which a cut lid does not enter the inside of a can container and can be opened with a slight force.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, a tab according to the present invention is provided with a raised portion at one end, a contact portion at the other end, a bent portion extending in the middle from the raised portion toward the contact portion, and a bent portion tip. Fixed to the lid having a score line engraved on the end panel of the can container with the abutting part being close to the winding part on the outer peripheral edge of the can container. When the pulling portion is raised, the bending portion bends to move in the direction of the winding portion, and the abutting portion abuts the winding portion.

[0006]

In the tab of the present invention, when the pulling portion is raised, the tab moves toward the tightening portion due to the bending of the bent portion, and the contact portion abuts on the tightening portion. When the pull-up part is raised further in this state, the lid's principle is based on the contact point between the contact part and the tightening part as a fulcrum. The tip is cut from the end panel along the score line and lifted upwards. From this state, if the pull-up part is pulled toward you, the lid will flip up and the opening operation will end.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of an upper portion of a can container having a tab according to an embodiment, 1 is a can container, 2 is an end panel (top panel) on the upper surface thereof, 3 is a winding portion at an outer peripheral edge thereof, 4 Is a lid formed on the end panel 2 and having a score line 5 that is partially carved in close proximity to the winding portion 3.

The tab 6 fixed to the lid 4 for opening the lid 4 has a ring-shaped raised portion 6 a at one end on the central side of the end panel 2 and at the other end near the tightening portion 3. The contact portion 6b has a substantially arcuate shape, and the contact portion 6b is connected to a connecting portion 6c forming a part of the raising portion 6a to form an O-shape. The bent portion 6d has a bent portion 6d extending from the middle portion of the connecting portion 6c toward the contact portion 6b, and a fixing portion 6e provided at the tip of the bent portion 6d. The fixing portion 6e is fixed to the lid 4 by riveting.

Next, the opening operation of the lid 4 by operating the tab 6 will be described with reference to FIGS. 2 to 4. FIG. 2 is a top perspective view of the can container 1 showing a state in which the tab 6 is in the middle of operation prior to opening the lid 4, FIG. 3 is a longitudinal sectional view of the same, and FIG. 4 is a can container after the lid 4 is opened. It is an upper perspective view of FIG.

When opening the lid 4, insert a toe between the raising portion 6a of the tab 6 and the end panel 2 and raise the raising portion 6a a little, and then, as shown in FIGS. 2 and 3, first. Then, the fingertip 7 is pryed into the pull-up portion 6a and then, as it is indicated by the arrow A, is pulled up. Then, the bent portion 6d is bent, and at the same time, the entire tab 6 slightly moves in the direction of the winding portion 3 shown by the arrow B (FIG. 2), and as shown in FIG. Contact at point P. When the pull-up portion 6a is raised further in this state, the tab 6 rotates about the fulcrum P in the direction of arrow A, and urges the lid 4 upward through the bent portion 6d and the fixing portion 6e. By this urging, the score line 5 is cut and the lid 4 is lifted up as shown in FIG. 3, and the opening 2a is formed in the end panel 2 where the lid 4 is cut open.

From this state, as shown in FIG. 4, when the pull-up portion 6 a is pulled in the direction of arrow C, that is, substantially horizontally to the side opposite to the opening 2 a, the lid 4 whose tip is cut along the score line 5 , The end panel 2 and the integrated base are left, and the end panel 2 is turned up and curved. This completes the opening operation of the lid 4 by the tab 6.

That is, in the tab 6 of the present invention, when the lid 4 formed with the score line 5 on the end panel 2 is opened, the lid 4 is flipped upward. It is not bent and made to enter the can container 1.

Further, in FIG. 3, the distance from the tip of the raised portion 6a to the contact point P is L, the distance from the fixed portion 6e to the contact point P is L / 2, and the finger 7 moves upward (in the direction of arrow A). If the applied force is F, then L · F = (L / 2) · 2F holds according to the lever principle. That is, the force of 2F, which is doubled, is applied to the lid 4, which means that the lid 4 can be easily opened by a slight operation force of the tab 6.

In the present embodiment, the lid 4 is not separated from the end panel 2, that is, the score line 5 is not formed so as to form a closed loop. However, the score line 5 is not separated. It is also applicable to a separable tab that is formed into a closed loop and in which the lid 4 separates from the end panel 2. Further, the lid 4 is not limited to being formed on a part of the end panel 2, but can be similarly applied to a lid having a substantially equal area to the end panel 2.

[0015]

[Effect of device]

 As described above, according to the present invention, when the raised portion of the tab in which the fixing portion formed at the substantially central portion is fixed to the lid is caused, the bending portion connected to the fixing portion is bent. By moving the tab in the direction of the wrapping part so that the contact part abuts on the wrapping part, the lever is lifted upward from this state using the lever principle to open the lid. As the lid does not enter the inside of the can, it is hygienic, and the opening operation of the lid can be easily performed with a slight tab operating force.
