Description

[Detailed description of the invention] Industrial field of application: This invention is a sake product that can be safely operated without damaging the fingertips when opening the container, and has a reliable sealing function and ease of opening. This invention relates to a sealing lid with a stopper for beverage bottles.

Prior art and its problems: Various structures have already been proposed for bottle seals for sake and other beverages, and some of them have been put into practical use, and their main structure is made of thin metal plates such as aluminum. It is carried out using a pot-shaped sealing lid made of plastic and an inner stopper made of synthetic resin or the like. This method requires two steps: first sealing the mouth of the bottle with an inner stopper, then placing a cap-shaped sealing lid over the neck of the bottle and sealing the bottle, which not only increases the construction cost but also makes sealing difficult. There are drawbacks such as the supplies being bulky and inconvenient to handle.
Recent models with a structure in which the sealing lid and the inner stopper are integrally formed, such as Utility Model No. 58-2774 and Utility Model Number 58-2775
As is known by the name, a stopper made of synthetic resin that can be fitted onto the bottle mouth, extends from the upper canopy to the flange, and a crown sealing body that fits around the outer periphery of the bottle mouth and serves as a seal. The metal crown seal is divided along the concave groove provided on the outer periphery of the flange part that just connects to the stopper body, and both divided edges are bent to form an integral part. On the other hand, when a consumer opens a cap that has been fitted and sealed, if it is opened along the cut line of the body of the cap like a conventional sealed cap, the outer surface of the cap is covered with a metal plate only on the canopy side. Although the plan was for the metal plate part of the body to be removed, in practice the crown seal, which was originally formed as one piece, was fitted into the synthetic resin stopper and then separated. Because the dividing edge is bent into the groove, it is difficult to reliably separate the canopy part and the body part that is removed when the package is opened, and the canopy part also lifts up when the package is opened. Situations may occur where the cap comes off, or the cap that was once separated and attached as a canopy of the cap loosens from its surroundings and comes off while the cap is being attached to and removed from the bottle mouth. There is a risk of injuring your fingertips with the cut end of the canopy. In order to solve this problem, the first step is to completely separate the canopy part and the body part that acts as a seal, and then bend the dividing edge into the groove provided in the stopper flange part. However, even if it is formed in this way, compared to the case of conventional aluminum sealing lids, it is simply integrated without using a separate inner stopper, and the gripping piece at the opening when opening the lid is Since it is a metal plate, there is no solution to the problem of the edges damaging the fingertips, which is a problem. In addition, it is possible to securely fix the sealing lid, and eliminate the disadvantages that occur due to the formation of various cut lines for opening, such as the cut lines that occur at the cut part due to the increased force required to open the seal, and sharp cuts at the tip of the incision hole. In order to eliminate the risk of the tip pointing outward and touching the pad of the finger and damaging it, we cut a diagonal wave-like uneven groove from the top plate of the sealing lid to a dimension of 1/3 or more of the total height to make it easier to open. It was established in 1972.
7469, Utility Model Publication No. 55-30832, etc. However, even with such a product, since the entire product is formed by pressing a thin metal plate, it is practically impossible to avoid the possibility of the finger pads being easily damaged by the edge of the gripping piece when opening the package. be. Furthermore, when using the structure with the weakened portion formed by the diagonal wave-like uneven grooves, it is first impossible to integrate the inner stopper and the sealing tube portion with the known structure, and secondly, the diagonally weakened line is tightened when sealing. It has many problems, including the fact that it is difficult to put into practical use because it cannot fully demonstrate its sealing function because it is easily broken by external contraction force, and these problems have not yet been solved.

Purpose of the invention: The present invention solves all of the problems of the conventional methods, fully demonstrates the sealing function, and can be opened safely without the risk of cutting the fingertips when opening. The object of the present invention is to provide a sealing lid in which a gripping/opening operation part of the body part of the sealing lid is formed of synthetic resin so that the plug body can be used as is as a replacement plug equipped with a metal canopy.

Structure of the invention: In order to achieve the above object, in the present invention, a bottle stopper made of a synthetic resin material is integrally formed with a thin-walled sealing outer cylinder part extending a required length from the outer periphery of the brim. A stopper is provided inside the outer cylinder concentrically with the outer cylinder, and a cut line of weakening is provided along the inner base of the outer cylinder near the contact surface of the bottle mouth rim. A line of weakening for opening is provided upward on the inner surface from the gripping piece to the cutting line of weakening, and the edge is bent into the locking groove provided on the outer periphery of the brim from the top surface of the bottle stopper, and a thin metal plate is formed. A canopy made of aluminum is covered and fixed, and the upper part is connected to the flange locking groove and the constriction locking part of the adjacent lower part from the flange locking groove of the bottle stopper to the bottle sealing tightening position on the upper part of the outer cylinder. A sealing ring made of a thin metal plate is fixed by rolling it around and squeezing it, and the sealing ring is knurled with a diagonal cut weakening line on the entire circumference of the back side and on the outer circumferential surface excluding the appropriate size of the sealing part at the lower end. The fixing constriction part and the lower end part are bulged outward.

Embodiment: Next, an embodiment of the bottle sealing cap of the present invention will be described in detail with reference to the drawings. The one shown in FIGS. A bottle stopper made of synthetic resin, which is integrally formed with a stopper 2 having an appropriately thick and elastic shape that fits into the bottle mouth, and a thin outer cylinder 3 that fits over the bottle neck from the outer edge of the bottle mouth. A plurality of seal annular protrusions 5 are provided at the portion in contact with the edge of the bottle mouth (this may be omitted), and a flange 4 connecting the stopper 2 and the outer cylinder 3 is provided.
A cutoff line of weakness 6 is provided along the entire circumference of a portion slightly below the inner circumferential surface where the outer cylinder 3 and the outer cylinder 3 are joined. The thin outer cylinder 3 of the bottle stopper 1 is provided with an opening 7 in which a gripping piece 8 is formed by cutting a portion from the lower end, and the opening 7 connects to the weakened line 6. In this way, a line of weakening 9 for opening is provided on the inner surface inclined at an appropriate angle. The outer cylinder 3 portion is relatively thin, and the portion adjacent to the line of weakness 9 for opening is thickened so as to be stronger than other portions (other means may be used). Also, tsuba part 4
A locking groove 10 is provided on the outer peripheral surface of the ring, and a groove 11 for locking the sealing ring is provided below the locking groove 10.

Reference numeral 15 denotes a canopy, which is made of a thin metal plate such as an aluminum plate, and is fixed by wrapping its lower edge into the locking groove 10 on the outer periphery of the flange 4 of the bottle stopper 1;
A sealing ring 16 made of the same thin metal plate as this canopy 15
When the capper is sealed by a capping machine, the sealing ring 16 is fitted around the outer periphery of the bottle neck up to the point where it is squeezed and sealed.
The upper end is rolled into the locking groove 10 and locked, and a slightly lower portion thereof is squeezed into the groove 11 and fixed integrally with the outer cylinder part 3 of the plug body. This sealing ring 16 is knurled with oblique cut weakening lines 17, 17' at an appropriate angle on the entire back surface and on the lower end 16' of the outer circumferential surface excluding the required tightening dimension l' for sealing. The section 1 in which the knurled concave-convex notch weakening line 17 is carved is a curved surface with an outward bulge.

The sealing lid of the present invention constructed in this way is handled in the same way as a conventional sealing lid equipped with an inner stopper, and when sealing, the sealing lid of the present invention is handled at the position of the annular groove 21 provided on the outer periphery of the bottle neck 20 as shown in FIG. By squeezing the lower end of the sealing ring 16 using a well-known capping machine, the outer tube 3 of the bottle stopper made of synthetic resin is squeezed and sealed. Since it is made of resin, it easily adapts to the bottle neck concave groove 21 and deforms, and since the sealing constriction part 18 does not have a line of weakness 17 on the outer periphery, the sealing ring 16 is constricted without breaking, and when deformed, the sealing ring 16 is compressed without breaking. Although the entire ring 16 is pulled downward, since the space between the upper constriction locking portion 19 and the constriction portion 18 is bulged, the pulling force is absorbed by this portion and the constriction locking portion 19 floats. The seal can be reliably sealed and maintained without falling or damaging the uneven cut line 17.

Next, when opening the package, as shown in FIG. Then, the outer cylinder 3 is torn, and when it reaches the lower end of the constriction part 18 of the sealing ring 16, the outer cylinder 3 is torn due to the many cut weakening lines 17' carved on the back side of the ring 16. If a pulling force is applied to the part that connects to the part, and the gripping piece 8 is strongly pulled, the sealing ring 16 will have weakened lines 17 and 17' from the inside and outside above the constricted part 18. It is easily torn, and the seal is torn to reach the cutting line of weakness 6 in the circumferential direction of the outer cylinder, and by tearing it in the lateral direction, 3 parts of the outer cylinder can also be removed. By opening the cap in this manner, the stopper 2 with the canopy 15 remains, so it is convenient to use this as it is as a replacement stopper after opening.

Incidentally, in accordance with the spirit of the present invention, the structure of the bottle stopper 1' can also be adopted as an annular stopper 2 as shown in FIG. In the drawings, the same parts as in the above-described specific example are denoted by the same reference numerals.

Moreover, any shape can be adopted for the cutting line provided on the synthetic resin outer cylindrical portion for opening and the shape of the gripping piece.

Effects of the invention: As described above, according to the invention, the sealing lid with bottle stopper, which had conventionally had many problems, has been improved, and the metal plate part does not have the role of sealing. The synthetic resin part is combined with the stopper to perform the function of holding and cutting when opening the seal, and the sealing ring has the main parts in a stable state so that the sealing part does not easily break, and once the seal is opened. If an external force is applied to the seal, it can be broken with a small amount of force, so it has weakened lines around its circumference, making it possible to seal it securely.
Moreover, it was possible to create a practically effective sealing lid that was safe and easy to open. In addition, since the present invention is completed by combining a synthetic resin bottle stopper with a metal plate forming the canopy and the sealing ring, the sealing ring formed on the metal plate sealing ring is By providing a large number of cut weakening lines in a knurled shape, you can achieve the purpose even if you match them at any position and combine them without specifying the position with the tear weakening line for opening on the outer cylinder side. It also has the advantage of increasing sexual
It can be provided at low cost.
