Abstract

(57) [Summary] [Problem to be solved by the invention] In the conventional invention, the present invention continues to have an advantage that the user can immediately recognize the case of unauthorized opening of the container, and recently, the one-way container is mainly a disposable container. The problem of causing waste pollution by being thrown away without being returned, and the technology of printing on the opening and the curved surface of the side of the conventional container has been developed, but the printing is performed for special technology. The cost is high, and in addition, there are problems that the printing surface is apt to be unclear and the loss ratio is large. Means for Solving the Problems A tear holding member 12 integrally formed of an elastic synthetic resin material and holding the lid 1 on a glass bottle 20, and a thin wall between the lid 1 and the tear holding member 12 In the lid 1 provided with the cut line 15 in the portion 13, an inward annular locking projection 9 is formed on the inner surface of the side wall 6 and an inward annular locking projection 10 is formed on the inner surface of the tear holding member 12. The problem is solved by means for providing a plurality of inwardly protruding cap pressing portions 8 at appropriate intervals on the inner wall 7 of the concave portion 3 constituting the lid 1.

Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 This invention concerns a safety cap for sealing bottles and bottles filled with milk, soft drinks, etc., preferably returnable bottles such as glass bottles, and for preventing unauthorized opening. The idea is that labels can be used for labeling.

[0002]

[Prior art]

 Most of these types of bottles / containers, which are sealed with a conventional lid, are mainly made of synthetic resin one-way containers, and for this reason, a method of attaching a label / seal on the container surface or printing on the container itself is adopted Have been. Conventional containers of this type are closed with lids for the safety of the filled contents. Once opened, even if the lid can be used for resealing, it must be recognized that the container has been opened. . Examples of this type of technology include the inventions described in JP-A-1-199861 and JP-A-1-240455.

[Problems to be solved by the invention]

 The present invention continues to have the advantage of being able to immediately recognize the case of unauthorized opening of the container in the conventional device.Recently, one-way containers are mainly disposable containers, and are thrown away without being returned, causing disposal pollution. In addition, although the technology to display such as printing on the opening of the container and the curved surface of the side surface has been developed, the printing cost is expensive due to the special technology, and the printing surface tends to be unclear. There are also issues such as a high loss ratio.

[0004]

[Means for Solving the Problems]

 Cut lines 15 are formed in a tear holding member 12 which is integrally formed of an elastic synthetic resin material and holds the lid 1 on a glass bottle 20, and a thin portion 13 between the lid 1 and the tear holding member 12. In the lid 1 provided, an inward annular locking projection 9 is formed on the inner surface of the side wall 6 and an inward annular locking projection 10 is formed on the inner surface of the tear holding member 12, and the lid 1 is formed. The problem is solved by means of providing a plurality of inwardly protruding cap holding portions 8 at appropriate intervals on the inner wall 7 of the recess 3 to be formed.

【Example】

 FIG. 1 is a partial cross-sectional perspective view of a product of the present invention. FIG. 2 is a plan view of the product of the present invention. FIG. 3 is an enlarged sectional view taken along line AA of FIG. The lid 1 is desirably integrally formed of an elastic synthetic resin material, for example, polyethylene / propylene or a copolymer of the two. The lid 1 is fitted into a glass bottle 20 and includes a recess 3 and a side wall 6. The side wall 6 is formed so as to hang down from an upper edge 5 of the lid 1. An annular locking projection 9 is formed. On the back surface of the concave portion 3, there is provided a tapered inner tubular portion 11 which is almost fitted into the bottle opening 22 of the glass bottle 20, and when the lid 1 is fitted into the bottle opening 22, the inner peripheral edge 23 of the opening is formed. It contacts the inner peripheral edge 2 of the lid 1. At the lower end of the side wall 6 of the lid 1, a tear holding member 12 for holding the lid 1 via the V-shaped groove 14 of the thin portion 13 of the elastic synthetic resin material is provided. A cut line 15 is provided at the center of the thin portion 13, a protruding piece 16 extends outward from one end of the tear holding member 12, and further has a square shape having the protruding piece 16 as a base. The tearing tag 17 extends outside the tear holding member 12. An upper end of the tearing tag 17 is in contact with the cut line 15, and an inwardly engaging annular projection 10 is provided on an inner surface of the tearing holding member 12. In the lid 1 configured as described above, a concave portion 3 is formed at the upper end of the lid 1, and the inner wall 7 of the concave portion 3 projects inward at an appropriate interval. Three cap retainers 8 are provided. The cap holding portion 8 is for fitting and holding the cap 18 indicating necessary items such as brand and quality placed on the bottom portion 4 of the recessed portion 3. The object of the present invention can be achieved even with the above-mentioned plurality. The cap 18 can also achieve the purpose by using a label. On the other hand, at the lower end of the bottle opening 21 of the glass bottle 20, bottle opening protrusions 24 and 25 circling the outside of the bottle opening 21 are provided in two stages. The bottle protruding portions 24 and 25 are fitted and held by the protrusions 9 and 10 of the lid 1. In the drawing, reference numeral 19 denotes a projecting tag for opening and closing the lid 1, which is provided at the lower end of the lid 1. The projecting tag 19 for opening and closing is used when the lid 1 is opened and closed again.

Next, the unsealing operation of the present invention will be described. First, when the tearing tag 17 is pulled outward, the cut line 15 is triggered, and along the cut line 15 of the lid 1 and the tear holding member 12. The tear holding member 12 starts cutting from the base of the tear tag 17, and the cutting proceeds along the score line 15. At this time, since the pulling force of the tearing tag 17 acts on the thin portion 13, the pulling force may be small. When the thin portion 13 is cut around the bottle opening 21, the tear holding member 12 is cut off from the lid 1, and there is no further cut. This means that the safety cap according to the present invention is ready to be opened, and the tear holding member 12 is cut off from the lid 1 so that the lid 1 is removed from the glass bottle 20 to open the bottle opening of the glass bottle 20. The part 22 is opened. The bottle opening 22 can be resealed again by using the opening / closing projection tag 19 of the lid 1 to be fitted and fitted into the bottle opening 22 again. If the safety cap according to the present invention is used for a returnable container such as the glass bottle 20 as in the embodiment of the present invention, the container can be returned.

[0007]

[Effect]

 According to the present invention, by using the tearing tag, when the lid and the tear holding member are separated and cut, it is possible to recognize that the bottle of the glass bottle has been opened or is in a state of being opened, and to know the unauthorized opening. be able to. In addition, the safety cap of the present invention has a recess formed in the lid, and the cap holding portion is provided on the inner side wall thereof, so that the glass bottle is separately printed between the cap holding portion and the bottom of the recess. It is technically easier to print on a cardboard or similar material than on a curved surface of a glass bottle because it is possible to fit a cap that displays and prints the brand and quality of the contents (contents) to be filled. It is possible to provide a safety cap that can be manufactured at a low manufacturing cost, and use containers such as glass bottles that have a clearer display than direct printing on bottles, and seal containers such as returnable glass bottles. It can also be used for clothing.
