Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for opening a can with a tab, that is, a device for opening a lid formed by engraving a score line on an end panel of a can container by means of a tab attached to the can.

[0002]

[Prior art]

 The device for opening a can with a tab cuts the lid along the score line by pulling up with a fingertip the tab fixed to the lid formed by the score line on the end panel of the can container and pulling the tab. Although there are those that are opened, conventionally, there are a separable type in which the lid and the tab are separated from the can container, and a non-separable type in which the tab and the lid are not separated from the can container.

In the detachable type, the tabs together with the lid having the sharp tip scatters everywhere and causes environmental deterioration and injury accidents. It is a non-separable type in which the tab and the open lid do not separate from the can container.

However, in the conventional non-separable type, for example, as shown in Japanese Utility Model Laid-Open No. 3-111939, when the tab is pulled up during the opening operation of the lid, the lid is bent inside the opening. It is designed to be used. Therefore, in this inward bending mold, when the can is opened, the lid that is bent inside the opening is immersed in or in contact with the liquid or solid material that is the contents of the can and adheres to the outer surface of the lid. It is pointed out that it is unsanitary because there is a risk that the dust and dirt that had been used will be mixed into the contents.

In view of this point, the inventor of the present invention has implemented an outward bending type opening device in which the lid cut when the tab is pulled up is bent outside the can. It was proposed in Japanese Patent Application No. 4-9 2032.

[0006]

[Problems to be solved by the device]

 The device for opening a can with a tab according to the above proposal raises the tab, abuts the tip of the tab on the can, and further raises the tab in the same direction. The lid is cut and moved to the outside of the opening, and then the tab is pulled in the opposite direction to enlarge the opening surface. However, in the opened state, the tab and the lid are exposed on the end panel side of the can, the tab extends in the pulling direction, and the lid is in the curved state and close to the opening. When drinking contents with a mouth, some people may feel that the lid and tab are obstacles, or that there is a risk of injury to the tip of the nose or lips.

In view of the above points, the present invention provides an external bending-type opening device for opening a can with a tab that prevents an obstacle from being injured or injured when the mouth is attached to the opening for drinking. The purpose is to provide a device.

[0008]

[Means for Solving the Problems]

 To achieve the above object, an opening device according to the present invention has a lid formed on a can end panel by a score wire and a tab fixed to the lid, and the score line is not completed. The lid is connected to the end panel at an incomplete portion, and the tab has a raised portion at one end, a fixed portion at the middle portion, and a pressing portion at the other end. However, the fixing portion is fixed to the lid at an intermediate portion between the tip portion of the lid and the non-completed portion so that the raising portion can be raised, and at least the pressing portion is the uppermost portion of the lid. It is characterized in that it has a width significantly larger than that of the lid, and when the raising portion is raised with a fingertip, the tip portion of the lid is pressed to start cutting the lid along the score line.

[0009]

[Action]

 With the above configuration, when you insert your fingertip between the raised part of the tab and the end panel and raise the tab, the pressing part of the tab acts as a lever with the fixed part as a fulcrum, and the tip part of the lid is pushed. Press to start cutting at the score line. As the tab continues to pull up, the tab width is greater than the maximum width of the opening, so the tab slides over the top edge of the incised opening towards the joint with the end panel of the lid, while simultaneously opening the lid. At the fixing point with the fixing part, it opens while folding in two. Pushing the tab in the direction opposite to the pulling direction to the end panel side opens the opening to the maximum and collapses the lid and the tab low. That is, in the opening device according to the present invention, it is possible to open the tab by raising the tab and pushing it down in the opposite direction. Then, with only one tab raising operation, the tip of the lid is pressed and cut, the middle portion of the lid is cut, and the lid is folded in two with the tab fixing portion as a boundary, and the opening operation is completed by the pushing down operation.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a top view of a can provided with an opening device according to an embodiment of the present invention. FIG. 2 is a process drawing showing the movement of the tab and the lid when opening.

In FIG. 1, 1 is an end panel of the can, 2 is a score line formed on the end panel, and the score line is formed into an elliptical non-complete ring. 3 is a lid formed by cutting the score line as described later, and is joined to the end panel at the non-completed portion of the score line.

Reference numeral 4 denotes a tab which is a main part of the present invention, and integrally has a pulling up portion 4a, a pressing portion 4b, and a fixing portion 4c. The raising portion 4a is formed in a ring shape so that a fingertip can be inserted into one end of the tab 4 and raised. The pressing portion 4b is formed on the other end portion of the tab, and the fixing portion 4c is formed on the middle portion of the tab, and is fixed at almost the middle portion of the lid 3. In this case, preferably the central portion of the pressing portion 4b is curved or protruded and positioned so as to press the tip portion of the lid 3 which is not opened when the raising portion 4a is raised. . Although the fixing portion 4c is not impossible to achieve the intended function of the present invention even if the fixing portion 4c is joined to the central portion of the lid 3, the fixing portion 4c is required to achieve a reliable purpose. It is preferable that at least both ends are joined near the score line. Further, the fixing portion 4c is provided with a bent portion 4c 'which extends slightly from the connecting portion 4d formed in the central portion of the tab to the pressing portion 4b side and bends when the pulling portion 4a is pulled up. Is desirable. Further, the tab 4 has at least a width at the pressing portion that is larger than the maximum width of the lid 4.

The operation of opening the can attached with the above-mentioned opening device will be described with reference to FIG. First, as shown in FIG. 2A, a fingertip is pushed between the raised portion 4a of the tab 4 and the upper surface of the end panel 1. When the fixing portion 4c has the bent portion 4c 'as described above, the fixing portion 4c bends when the fingertip is pushed in, and the tab can be easily pulled up. If the tab is continued to be pulled up, the tab becomes a lever with the fixed part 4c as a fulcrum when the fixed part can no longer bend, and as shown in FIG. 2 (b), the pressing part at the tip of the tab is pressed. The score line 2 begins to be cut because 4b strongly pushes down the tip of the lid 3. That is, the lid starts to be opened from its tip.

When the tab is further pulled up, the width of the pressing portion 4b of the tab is larger than the maximum width of the lid 3, so that the pressing portion does not go into the opened opening 5 and As shown in FIG. 2 (c), the upper surface of the opening edge starts to slide toward the joint portion of the lid, and at the same time, the pressing portion 4b of the tab presses and cuts the other portion of the lid. However, since the fixed portion 4c serves as a fulcrum, the middle part of the lid is lifted when the movement of the end of the tab toward the connecting portion of the lid is started, and the score line is sequentially cut toward the connecting portion to open the lid. It is opened and bent in two at the joint with the fixed part. When the pull-up angle of the tab exceeds 90 °, the lid is folded to a U-shape or a V-shape as shown in FIG. 2 (d).

Next, the tab is pushed down toward the upper surface of the end panel in the direction opposite to the pulling up direction, and the lid 3 is folded in two and crushed on the upper surface of the end panel together with the tab. The opening 5 is opened to the maximum. If a thin portion that linearly extends in the width direction of the lid is formed at a position where the fixing portion 4c of the lid 3 is fixed, the lid easily bends at the thin portion when the tab is pushed down and becomes flat. be able to.

Therefore, it is possible to drink the contents of the can by putting a mouth on the opened opening 5 or to pour the contents out of the opening. At this time, the tabs 4 and the lid 3 are in the minimum protruding amount so that they do not become an obstacle, and the lid 3 having a sharp tip edge is covered with the tab 4, so that the lip There is no danger of injuring your nose or tip.

The shape of the tab 4 is not particularly limited. In the illustrated example, the space between the pressing portion 4b and the fixed portion 4c is hollowed out by pressing when the tab is manufactured in order to save the material for the tab, but it may be closed with the material for the tab.

[0018]

[Effect of device]

 As explained above, in the opening device of the present invention, when the tab is pulled up, this causes the lid to start to open easily due to the lever action, and moreover, the lid only moves along the opening surface so that it can be inserted into the opening. Since it does not enter, unlike the past, the contents are not contaminated by the lid, and the lid is completely opened and covered by the tab only by the pushing operation in the direction opposite to the tab raising operation. Therefore, the tab and lid do not become an obstacle or cause an injury when the mouth is opened to drink the contents, and it is very convenient and safe.
