Description

The present invention relates to a container lid, and more particularly to a container lid provided with an inner stopper.

As a conventional container lid, Patent Document 1 discloses an outlet plug with a pull ring attached to a bag-shaped container made of a flexible packaging material. This outlet plug is equipped with an inner plug that can be cut with a half-cut groove by pulling up the pull ring, and by forming a half-cut groove so that the inner plug can be pulled up spirally, it looks like a wet tissue container. Even when the outlet is large, the force acting on the connecting portion of the pull ring is suppressed to prevent the pull ring from being cut.

However, with the above-mentioned conventional outlet plug, depending on the force and direction for pulling up the pull ring, the inner plug may be cut at a place different from the half-cut groove, which may make it difficult to remove the entire inner plug. there were.

Therefore, an object of the present invention is to provide a container lid in which the inner plug can be easily and surely removed.

The object of the present invention is a container lid including a main body having a tubular portion and an inner plug connected to the inside of the tubular portion via an annular first thin-walled portion, wherein the inner stopper is provided. A second thin-walled portion that protrudes from the surface and extends from the first thin-walled portion in a curved shape so as to surround the pull-up portion so that the inner plug can be cut in a spiral shape together with the first thin-walled portion. The thin-walled portion and the first thick-walled portion formed on the tip side of the tip portion of the second thin-walled portion are provided , and the inner plug is the first thin-walled portion and the second thin-walled portion. A second thick portion formed along the inside and connected to the first thick portion, and a third thick portion formed along the outside of the cutting start portion in the second thin portion. The third thick portion is achieved by a container lid that is not connected to the first thick portion.

According to the present invention, it is possible to provide a container lid in which the inner plug can be easily and surely removed.

It is a top view of the container lid which concerns on one Embodiment of this invention. It is a front view of the container lid shown in FIG. It is an enlarged view of the part A of the container lid shown in FIG. It is a bottom view of the main part of the container lid shown in FIG.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a plan view of a container lid according to an embodiment of the present invention. As shown in FIG. 1, the container lid 1 is made of, for example, a synthetic resin, and is provided on the main body 10 having a cylindrical tubular portion 11, the outer lid 20 for opening and closing the tubular portion 11, and the tubular portion 11. It is provided with an inner plug 30.

The main body 10 includes a support portion 12 that supports the outer periphery of the tubular portion 11, and a flange portion 13 that is provided on the peripheral edge of the support portion 12 via a fitting wall 14, and is formed in a rectangular shape as a whole. ing. The fitting wall 14 is provided in a frame shape so as to project upward from the flange portion 13.

The outer lid 20 is provided with a sealing portion 21 formed of a double ring on the inner surface side, and is rotatably attached to the main body 10 via a hinge portion 22. When the outer lid 20 is closed from the open state as shown in FIG. 1, the tip of the tubular portion 11 is fitted into the gap of the double ring of the sealing portion 21 and sealed, and is shown in the front view in FIG. As described above, the outer lid 20 is fitted inside the fitting wall 14.

The inner plug 30 is formed in a disk shape, and is connected to the inside of the tubular portion 11 via an annular first thin-walled portion 15. The inner plug 30 includes a pulling upper portion 31 made of a pull ring or the like provided on the upper surface side, a second thin-walled portion 32 extending from the first thin-walled portion 15 so as to surround the pulling upper portion 31, and a second thin-walled portion. A first thick-walled portion 33 formed on the tip side of the tip portion T of the portion 32, and a second thick-walled portion formed along the inside of the first thin-walled portion 15 and the second thin-walled portion 32. It is provided with a unit 34.

The first thin-walled portion 15 and the second thin-walled portion 32 are composed of half-cut lines formed so that the thickness of the inner plug 30 is reduced. When the pull-up portion 31 is pulled up, cutting of the second thin-walled portion 32 is started from the cutting start portion C in the vicinity of the pull-up portion 31, and cutting proceeds along the second thin-walled portion 32 and the first thin-walled portion 15. Thereby, the inner plug 30 can be spirally cut and separated from the tubular portion 11.

FIG. 3 is an enlarged view of part A of the container lid 1 shown in FIG. As shown in FIGS. 1 and 3, the first thick portion 33 and the second thick portion 34 are formed in a rib shape on the upper surface side of the inner plug 30. The first thick portion 33 is formed in an arc shape from the tip portion T of the second thin portion 32 so as to mainly cover the cutting direction side (arrow pointing B direction side) of the inner plug 30. The second thick portion 34 has an annular portion 34a formed on the entire inside of the first thin portion 15 and a curved portion 34b formed on the entire inside of the second thin portion 32 with the annular portion 34a as a base end. The tip of the curved portion 34b is connected to the first thick portion 33.

As shown in FIG. 2, the container lid 1 having the above configuration has a fitting wall 14 inserted into the mouth portion 51 of a container 50 made of a flexible packaging bag or the like from below to project, and the flange portion 13 has a flange portion 13. The upper surface can be fixed to the peripheral edge of the mouth portion 51 by adhesion or the like, and the contents such as a decorative sheet and a wet tissue can be taken out from the tubular portion 11 by cutting off the inner plug 30 at the time of use. Since the first thick portion 33 is formed on the tip side of the inner plug 30 with respect to the tip end portion T of the second thin wall portion 32, the cutting toward the tip end direction of the second thin wall portion 32 is performed. It can be reliably blocked by the thick portion 33 of 1. As a result, it is possible to prevent the inner plug 30 from being cut at an unintended location, and the inner plug 30 can be easily and surely removed. The tip T of the second thin portion 32 is preferably in contact with the first thick portion 33, but the first thick portion 33 may be provided at a position slightly distant from the tip T.

Further, by forming the second thick portion 34 along the inside of the first thin portion 15 and the second thin portion 32, it is possible to reinforce the peripheral edge portion of the inner plug 30 to be cut off. By connecting the second thick portion 34 to the first thick portion 33, the inner plug 30 can be more reliably cut along the first thin portion 15 and the second thin portion 32. Can be done.

As shown in the bottom view of FIG. 4, the inner plug 30 of the present embodiment also has a first thick portion 33 formed on the lower surface thereof. The first thick portion 33 may be formed only on either the upper surface or the lower surface of the inner plug 30. On the lower surface of the inner plug 30, a third thick-walled portion 35 formed along the outside of the cutting start portion C in the second thin-walled portion 32 is provided, whereby the inner plug from the cutting start portion C is provided. The cutting of 30 can be performed more reliably. The second thick portion 34 and the third thick portion 35 can also be formed on one or both of the upper surface and the lower surface of the inner plug 30 in the same manner as the first thick portion 33.
