Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a sealing material, and more specifically, it is used so as to close and fix a pouring hole such as the neck of a container body or an inner stopper for pouring, and peel it off when the container is used to open the pouring hole. Sealing material.

[0002]

[Prior art] [Problems to be solved by the device]

 For example, there is an inside plug for pouring in which the peripheral wall is fitted and fixed to the outer peripheral upper end of the container neck and the upper wall with a pouring hole extending from the upper edge of the peripheral wall closes the upper neck neck opening. It is known that a sealing material made of a synthetic resin sheet or the like is fixed to the upper surface of the top wall of the inside plug by an appropriate fixing means such as fusion bonding or adhesion to seal the pouring hole liquid-tightly. Has been done. In addition, these sealing materials have a tongue projecting laterally when used, and the portion fixed to the top wall is scraped off to open the pouring hole.

However, in the conventional sealing material of this type, if the sealing strength of the sealing material is too strong, the sealing material is naturally difficult to peel off, and only a part of the portion fixed to the tongue is peeled off to open the pouring hole. If the seal strength is weak, there is a risk of liquid leakage. Therefore, it is necessary to adjust the seal strength one by one at the stage of fixing the sealing material, and there is a drawback that the production efficiency is deteriorated accordingly.

The present invention proposes an excellent sealing material that solves the above-mentioned drawbacks of the prior art.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the sealing material of the present invention has a sheet-like base 9 on the top surface of the peripheral edge of the pouring hole 6 that closes the pouring hole 6 and is fixed to the top surface of the pouring hole 6. The tongue piece 10 for finger hanging is integrally projected toward the one side, and it originates from one side of the base end of the tongue piece 10 and bypasses the vicinity of the spout hole 6 to the other side of the base end portion of the tongue piece 10. A break line 11 was provided to reach the structure.

[0006]

[Action]

 When holding the tongue piece 10 and pulling it toward the center, the base 9a outside the break line 11 remains on the plug body 2, and the base 9b surrounded by the break line 11 is scraped off and poured as shown in FIG. Although the discharge hole 6 is opened, the area of the fixed portion in the fracture line 11 is small, so that the discharge hole 6 can be easily and surely opened.

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIGS. 1 to 4 show an embodiment of the present invention. In this embodiment, a case where a sealing material 3 is attached to a plug body 2 to form an inner plug 1 for pouring will be described.

The plug body 2 is made of synthetic resin, and has a cylindrical shape with a lower end surface opening in which a top wall 5 extends from the upper edge of the peripheral wall 4, and a circular spout hole 6 is formed in the center of the top wall 5. Has been drilled. An upward step 7 is provided around the upper surface of the top wall 5. Further, a seal tube portion 8 is vertically provided on the back surface of the top wall 5 at a position spaced apart from the peripheral wall 4 by a predetermined distance.

The sealing material 3 is made of a synthetic resin alone or a laminated sheet, or a laminated sheet of a synthetic resin and paper, metal, or the like. The sheet-shaped base 9 has a plate shape in which a finger-holding tongue piece 10 is integrally projected from one side edge of the sheet-shaped base 9, and in this embodiment, as shown in FIG. A plate-shaped finger hanging tongue piece (10) is integrally extended. The size of the sheet-shaped base portion 9 is made slightly smaller than the top wall portion of the plug main body inside the above-mentioned step 7 so that the tongue piece 10 projects into the step 7 when mounted on the plug main body 2. ing.

The base portion 9 of the sealing material 3 is provided with a break line 11 made of perforations, thin-walled lines, etc., which can be easily broken. The breaking line 11 starts at one side of the base end of the tongue piece 10 when the sealing material 3 is fixed to the plug body 2 and extends in the center direction to bypass the vicinity of the spout hole 6 and tongue piece 10 pieces. It has the shape of a keyhole provided at the other end.

The sealing material 3 thus constructed is fixed to the upper surface of the top wall 5 of the plug body 2 by an appropriate fixing means such as adhesion or fusion to seal the pouring hole 6, and as shown in FIG. Get stopper 1.

As shown in FIG. 3, for example, the above-mentioned inner plug 1 for pouring is made of synthetic resin with a top wall 14 extending from an upper end of a peripheral wall 13 screwed onto the outer periphery of a container body neck portion 12. It is used for a container to which a cap 15 is detachably attached, and a peripheral wall 4 is fitted and fixed to the outer circumference of a diameter-reduced mouth-neck 12a formed by reducing the upper end of the mouth-neck 12 with concave-convex engaging means, and a seal is provided. The tubular portion 8 is used by being fitted into the inner surface of the reduced diameter neck portion 12a in a liquid-tight manner.

The present invention is not limited to the above-described embodiments, and the shape, material, structure, etc. can be appropriately changed without departing from the scope of the present invention. In the above examples, the case where the sealant was attached to the body of the inner stopper plug was described, but it is also possible to apply the sealant directly around the outlet hole at the upper end of the neck and neck of the container body. It is also possible to apply to a container having holes.

[0015]

[Effect of device]

 As described above, the sealant of the present invention has a break line that starts from one side of the base of the tongue piece and bypasses the vicinity of the closed pouring hole to reach the other end side of the base of the tongue piece. If you pull it by pulling, the part inside the rupture line fixed along the rupture line may be scraped off.Because the fixed part inside the rupture line is small, the pouring hole should be opened easily and surely. Can be done.

Further, since the sheet-like base portion outside the rupture line upon the opening of the pouring hole is configured to remain on the top surface of the plug body, and the portion to be removed inside the rupture line is a small fixed portion, for example, a seal It is only necessary to set the strength to a certain level, and it is not necessary to adjust the seal strength one by one as with conventional products, and as a result, efficient sealing work can be performed and production efficiency can be significantly improved.

Further, since the sheet-like base portion is broken along the breaking line, only the necessary portion can be removed without removing the excess portion, and only the tongue piece and the base portion can be removed. As a result, there is no possibility of causing inconvenience such as the opening of the pouring hole.
