Easy-open container lids are known.

0003 However, when opening this type of container lid, first move the tension member in the vertical direction of the container. Pull it straight at right angles to the object, and then pull the tension member upward. is considered to be the appropriate method. However, consumers are unable to open the can. As we have experienced with the tensile members for bottles, the tension members are also used in the container lids of bottles. In most cases, the material is initially pulled straight upward along the length of the container. Therefore, in the container lid, the tear tab can be accurately pulled from the tear starting end. The tensioning member is attached to the tear tab without tearing, but the tear tab is broken and the lid cannot be opened. The problem has arisen that the system is separated from the In addition, in this case, the consumer There is also a risk of cuts to fingers etc. due to the sharp parts of the broken tear tabs.

0004 From the perspective of preventing such problems and dangers, this type of container lid has traditionally been used. Various improvements have been proposed. For example, pull the tear tab and tension member together. The tear tab and the tensile member are deformed from approximately the vicinity of the lower edge of the skirt portion. By providing a protrusion toward the outside of the container over the connection with the tensile member When pulling the tension member upward, the tension member does not bend at the connection with the tear tab. , the tensile member and the tear tab are bent integrally over the protrusion of the tear tab, and this During the process, the tear is achieved smoothly from the tear initiation end, and then the tensile member is further pulled. When raised, the protrusion comes into contact with the skirt and the tension member contacts the tear tab and container lid. A lever action is created between the tear tab and the tear strip, which allows the tear tab to adhere to the preset tear A container lid configured to achieve positive tearing has been proposed (Japanese Patent Publication No. 1-463). Publication No. 86). Additionally, a tension member is provided adjacent to the connection portion between the tear tab and the tension member. By providing a protrusion parallel to the center line of the tension member at the base of the tension member, When you pull it up, the top end of the protrusion hits the tear tab, and that point becomes the fulcrum of the lever. Container lids have also been proposed that have tear tabs that can be easily torn. Publication No. 2-21402).

The container lid 12 includes a top portion 14 and a skirt portion 16. It is made of thin metal plate material such as stainless steel or aluminum. This capacity Two tear lines 18, 18 extend from a part of the skirt portion 16 of the lid 12 to the top portion 14. is engraved to form a tear strip 20 for opening the container lid 12. Also, this The lower edge of the skirt portion 16 on which the tear strip 20 is formed is allowed to extend slightly downward as it is. to form tear tabs 22. And a tear strip 20 in which this tear tab 22 is formed. Along the tear lines 18, 18, the lower edge of the skirt portion 16, which is the tear start end, is In this way, slight cuts 24, 24 are provided.

[0015] However, in the container lid 12 of this embodiment, there are some steps to facilitate the opening operation. The tensioning member 26 is made of plastic material and has a ring shape, and the tensioning member 26 is made of a plastic material and has a ring shape. The tip of the tear tab 22 is integrally molded by embedding and combined with the tear tab 22. Configure. In this case, the connection between the ring-shaped tension member 26 and the tear tab 22 The portion is integrally provided with a first protrusion 28 that protrudes outward. Note that this protrusion 28 is a chevron extending in the width direction of the tear strip 20, and as shown in FIG. so that when it is pulled up, its tip touches the upper part of the skirt portion 16 of the tear strip 20. It is preferable to configure it as follows.

[0016] Therefore, in the container lid 12 of this embodiment, the tip of the first protrusion 28 is A second protrusion 30 is provided in a protruding manner above the skirt portion 16 of the tear strip 20 in contact with the tear strip 20. In this case, since the second protrusion 30 is formed on a thin metal plate, it may be formed on a skirt, for example. When carving two tear lines 18, 18 from a part of the bottom part 16 to the top part 14, It can be easily formed into a spherical protrusion by pressing.

[0017] According to the container lid 12 of this embodiment configured in this way, when opening it, , first pinch the tension member 26 and immediately pull it upwards, as shown in Figure 2. The tear tab 22 bends and the tension member 26 changes from a vertical position to a horizontal position. When the tip of the first protrusion 28 provided on the tension member 26 is the skirt portion 1 of the tear band 20 6 and abuts against the second protrusion 30 located above the second protrusion 30 . Therefore, If the tension member 26 is further pulled upward, the tension member 26 Using the protrusion 28 of 1 as a fulcrum, a lever action is generated to pull the tear tab 22 outward (in the horizontal direction). ) exerts a strong pulling action on the At the same time, the tear tab 22 Using the second protrusion 30 as a fulcrum, a lever action is generated and the tearing start end of the tear strip 20 is On the other hand, it exerts an action that strongly pulls it outward. As a result, the tensile member 2 6 can be pulled upward with a relatively light force, and it can be torn. Accurate and safe tearing of the tear strip 20 by the tabs 22 can be achieved.

This shows the case where it is provided above the tearing part 16, that is, above the tearing start end of the tearing band 20. However, in this embodiment, the second protrusion 30 is connected to the skirt portion 1 of the tear strip 20. 6, that is, below the tear starting end of the tear band 20.

[0019] Even in this configuration, the second protrusion 28 is connected to the tension member 2. 6 will not directly collide with the first protrusion 28 when pulled upward, but it will tear. When the tab 22 is bent, it comes into contact with a part of the tensile member 26 and the tear tab 22 is A similar leverage effect as in the example occurs to achieve accurate and safe tearing of the tear strip 20. I can do that. Note that the tip of the first protrusion 28 of the tensioning member 26 is also tearable. It abuts against the upper part of the skirt portion 16 of the band 20, creating a leverage action and releasing the tear tab 22. It is possible to exert a strong pulling action in the direction (horizontal direction).
