Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cap used for a container such as a toothpaste tube, a bottle, and a bottle.

[0002]

[Prior Art]

 Conventionally, plastic caps that can be opened and closed with one hand have been used to open the openings of containers such as toothpaste tubes, bottles, and bottles.

Since such a cap can be opened and closed very easily, the cap may be opened at the store before the consumer purchases it. Therefore, it is not possible to guarantee that the cap is not opened before actually using it. It was

Therefore, conventionally, a toothpaste is placed in a box one by one and sealed, or a bottle, a bottle, etc. containing food is provided with an inner seal at the mouth, so that the consumer once removes the cap. After removing the inner seal, the cap was attached and used again.

[0005]

[Problems to be solved by the device]

 It is an object of the present invention to provide a cap that is capable of remedying the above-mentioned conventional drawbacks and preventing unopening before use.

[0006]

[Means for Solving the Problems]

 The cap of the present invention has a cap body tightly fitted to an opening edge of a container, an opening provided at the center of the cap body, and an opening part which is pivotally supported on one side of an upper portion of the cap body to open and close the opening part. A lid body, a projecting piece whose base end is connected to the other side of the upper part of the cap body by a minute connection part, and the projecting piece is inserted when the lid body closes the opening. A hole; and an extending portion formed laterally on the tip end of the projecting piece and having an inclination that expands from the center of the tip end of the projecting piece toward the base end direction and extends more than the lateral width of the hole. It is characterized by that.

[0007]

[Action]

 Since the container is first filled with the filling material and the container is opened first, when the opening of the cap body that is tightly fitted to the opening edge of the container is closed with the lid, the extension on the side of the tip of the protruding piece is inward. After contracting and deforming to pass through the hole in the lid, it is expanded and restored.

When the lid is pivoted in the direction away from the cap body to release the opening, the extending portion on the tip end side of the projecting piece is caught in the hole of the lid, and the projecting piece is pulled to project the projecting piece at the minute connecting portion. Tear off the cap body.

【Example】

 An embodiment of this invention will be described below.

FIG. 1 is a front view showing an unused state of a lid according to an embodiment of the present invention, and FIG. 2 is a vertical right side view of FIG. 1, in which a cap body 1 is made of synthetic resin. The top plate 2 (see FIG. 2) is provided on the upper part, and a cylindrical opening 3 is provided at the center of the top plate 2. The cap body 1 is closely fitted to the outer periphery of the opening edge of a toothpaste tube, bottle, bottle, etc., and a lid 4 is pivotally supported by a thin hinge part 5 on one side of the upper part of the cap body 1. There is.

An annular projection 6 is provided on the inner surface of the lid body 4, and the lid body 4 is rotated counterclockwise around the hinge portion 5 from the open state of FIG. In the closed state, the annular projection 6 is tightly fitted to the outer periphery of the upper end of the opening 3 so that the upper end of the opening 3 can be closed. A rectangular hole 7 is formed at a position facing the hinge portion 5 of the lid body 4, and when the lid body 4 is closed, a protruding piece 8 described below is inserted into the hole 7. There is.

As shown in FIGS. 1 and 2, on the other side of the upper portion of the cap body 1 facing the hinge portion 5, a protruding piece 8 is provided so as to project upward. The lower base end of the projecting piece 8 is connected to the upper part of the cap body 1 by a minute connecting portion 9 having a small cross-sectional area, and the upper end of the projecting piece 8 spreads downward from both sides from the center of the tip. A stretched portion 11 having a slope 10 is formed. As is clear from FIG. 1, the dimension between the left and right ends of the extending portion 11 is larger than the lateral width of the hole 7 formed in the lid body 4 in the left-right direction. The stretched portion 11 has elasticity based on the synthetic resin material.

FIG. 3 is a front view when the lid is first closed, FIG. 4 is a plan view of FIG. 3, FIG. 5 is a right side view of the vertical section of FIG. 3, and FIG. FIG. 3 is a front view of the first closed state when the lid 4 is rotated from the open state of FIG. 2 in a counterclockwise direction about the hinge portion 5 as a rotation center to a closed state. Immediately before the body 4 is closed, the upper end of the protruding piece 8 is inserted into the center of the hole 8. Then, both ends of the hole 8 come into contact with the slope 10 and move downward, and the extending portion 11 expanding downward on both sides contracts and deforms inward toward the center side and passes through.

When the lid body 4 is closed, the annular projection 6 is tightly fitted to the outer periphery of the upper end of the opening 3 to close the upper end of the opening 3. At this time, as shown in FIGS. 3 and 6, the hole 8 is located below the extending portion 11, and the extending portion 11 that has been contracted and deformed inward on the center side is expanded by elasticity, and the left and right sides of the extending portion 11 are expanded. The dimension between both ends is restored to a dimension larger than the lateral width of the hole 7 in the left-right direction. When the lid body 4 is closed in this way, the locking projections 12 (see FIGS. 2 and 5) projectingly provided on the top surface of the top plate 2 come into close contact with the inner side surface of the lid body 4 to close the lid body 4. The state will be maintained. As shown in FIG. 6, the cap body 1 is tightly fitted to the opening edge of the container 13, and the container 13 whose contents are sealed by the lid 4 of the cap body 1 is displayed at the store.

When attempting to open the closed lid body 4, when the lid body 4 starts to rotate clockwise from the closed state of FIG. 5 with the hinge portion 5 as a rotation center, both sides of the hole 7 are stretched. The extension portion 11 is pushed up by coming into contact with the lower side of the portion 11. For this reason, the extending portion 11 tends to further spread, and the entire projecting piece 8 is strongly pulled upward by the hole 7, and finally the minute connecting portion 9 is broken and the projecting piece 8 is removed from the cap body as shown in FIG. 1 will be separated and the protruding piece 8 will be lost.

As described above, the protruding piece 8 is connected to the cap body 1 of the cap in which the lid body 4 is not opened at all, but the cap in which the lid body 4 is opened even once does not protrude from the cap body 1. 8 is separated and lost.

[0017]

[Effect of the device]

 The cap of the present invention can determine whether the cap is completely unopened or has been opened depending on the presence or absence of the protruding piece, which can be used as a reference when purchasing a product, and has the effect of preventing the cap from being opened unnecessarily.

When the lid is first closed at the manufacturing plant, the extending portion contracts and deforms inward on the center side and passes through the hole, so that there is no effect on the operation of closing the lid at all.
