【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 tabs according to an embodiment, 1 is a can container, 2 is an end panel (top panel) on the upper surface, 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 contact portion 6b, and the contact portion 6b is connected to a connecting portion 6c forming a part of the raising portion 6a to form a substantially θ shape. The tab 6 has a bent portion 6d extending from the intermediate 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 caulking or 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 of the tab 6 standing up 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 the lid 4 is opened, a toe or fingertip is inserted between the raising portion 6a of the tab 6 and the end panel 2 and the raising portion 6a is slightly raised, and subsequently, as shown in FIGS. 2 and 3. In this way, the fingertip 7 is pryed into the pull-up portion 6a and then pulled up as shown by the arrow A. 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. Abut at points. When the pull-up portion 6a is raised further in this state, the tab 6 rotates about the fulcrum P in the direction of the arrow A, and biases the lid 4 upward through the bent portion 6d and the fixing portion 6e. By this urging, the score line 5 is cut, 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, the tab 6 of the present invention is designed so that when the lid 4 formed with the score line 5 on the end panel 2 is opened, the lid 4 is flipped upward.

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.

Next, as shown in FIG. 4 when the lid is opened, the tab 6 and the lid 4 that have been pulled up or separated from the outside of the can container are left as they are after the contents are consumed. It is dangerous if discarded. Therefore, in the above-described embodiment, the opening 2a and the tab 6 are set to dimensions such that the tab 6 can be gripped and pushed together with the lid 4 into the can container through the opening 2a.

However, as shown in FIG. 4, the lid 4 pulled up by the tab 6 may have its tip standing up from the space between the tabs, and the tab is pushed into the can container to push the lid and the tab together. Dangerous when storing. FIGS. 5 to 8 show a second embodiment in which the above problems when the tab and the lid are housed in the can container are improved. That is, as shown in FIG. 5, when the tab 6A of this embodiment is pulled up by the tab 6A between the connecting portion 6c, the bent portion 6d, the fixing portion 6e and the contact portion 6b, A cover portion 6f is formed integrally with the contact portion 6b to prevent the tip portion of the lid from standing up between the tabs.

With the addition of the cover portion 6f, as shown in FIG. 7, when the lid 4 is pulled up and turned up by the tab 6A, the lid 4 does not stand upright from the tab 6A. When holding and pushing this into the can container through the opening 2a, the tab 6A and the lid 4 can be safely stored without injuring a fingertip with the tip of the lid, as shown in FIG. . As a result, the can container can be handled or disposed of after consumption of the contents without sharp and dangerous protrusions.
