Abstract

(57) [Abstract] [Purpose] A hinge cap of a type in which a synthetic resin lid is provided on a synthetic resin base through a hinge is processed into a base and a lid, and each has a special function. There is a case to let. In this case, the hinge conflicts with either or both functions. Therefore, a hinge cap that eliminates the above contradiction is provided. A lid made of synthetic resin is provided on a base made of synthetic resin via a hinge, and the hinge is made of a material different from that of the lid and the base and made of an elastic body.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a hinge cap mounted on a container such as a bottle and used.

[0002]

[Prior art]

 Conventionally, a hinge cap as shown in FIG. 3 has been widely used. Since the present invention is an improvement on the conventional hinge cap described above, the conventional hinge cap will be described first.

In FIG. 1, reference numeral 41 is a synthetic resin mounting portion for mounting on a bottle or the like, 42 is a pouring cylinder provided in the mounting portion 41, and 43 is a main body formed in this way. A mouth wall 44 is integrally formed inside the main body 43. Reference numeral 45 is a tear groove, 46 is a tear portion, and 47 is a tear member provided on the tear portion 46. Reference numeral 48 is a lid integrally provided on the main body 43 via a hinge 49, 50 is a bent portion, and 51 is a second hinge.

Both the hinge 49 and the second hinge 51 serve as a mechanism for maintaining the posture at the time of opening, that is, preventing the overhang due to the sagging at the time of pouring. Further, in FIG. 3, reference numerals 52 and 53 respectively denote an engaging portion and a locking portion which are firmly locked when the lid 48 is closed.

The hinge cap thus formed is made of synthetic resin, for example, polyethylene, which is easy to tear, because the tearing member 47 is pulled upward when it is opened to tear the tear groove 45. . The conventional cap is widely used because it can seal the container until the first opening.

[0006]

[Problems to be solved by the device]

 However, the conventional hinge cap described above has the following drawbacks. It is made of a synthetic resin having a small tear strength, for example, polyethylene so that the tear groove 45 can be easily torn, but when the hinge 49 is bent from the bent portion 50 or the like, the hinge 49 is cut at the same portion 50. Have the risk of

Further, the lid body 48 is covered on the main body 43 at the time of closing, and the locking portion 53 thereof is strongly locked to the engaging portion 52 of the main body 43, so that a predetermined hardness is required. That is, the hinge 49 may require contradictory performance from both the main body 43 and the lid 48.

The present invention was made in order to solve such a problem, and the purpose thereof is to exert the function without being affected by the main body 3 and the lid 9 even if they have arbitrary functions. To provide a hinge cap having a hinge that can be.

[0009]

[Means for Solving the Problems]

 This invention which achieves the above-mentioned object is described as follows. A synthetic resin lid 9 is provided through a hinge 8 and a synthetic resin base 3 is made of a different material from both the base 3 and the lid 9. And a hinge 8 which is an elastic body having elasticity. The hinge 9 is the hinge cap made of rubber.

[0010]

[Action]

 This hinge cap is configured as described above, and since the hinge 8 is made of an elastic material having a different material from both the base body 3 and the lid body 9, the hinge body 8 has the same structure as the conventional example. As shown, even if a material such as a fissure is formed to facilitate tearing, or if, for example, the lid 9 is formed with a relatively hard engaging portion that firmly engages with the main body 3, the functions thereof are sufficiently performed. Can be worked on. Moreover, the hinge 8 has a strong bending resistance, works well for a large number of times of elastic bending, and is not easily broken.

[0011]

【Example】

 In FIG. 1, reference numeral 1 denotes a mounting portion made of synthetic resin, for example, polyethylene, which is formed so as to be attached to a bottle mouth (not shown) as an example. Reference numeral 2 denotes a pouring tube, which is integrally provided on the upper portion of the mounting portion 1 and the base body 3 is formed by the both. Reference numeral 4 denotes a mouth wall integrally formed inside the base body 3, and an endless fissure groove 5 is formed in the mouth wall 4, whereby a tear portion 6 is formed inside thereof.

Reference numeral 7 is a pull ring-shaped tearing member. A lid 9 is provided on the base body 3 via a hinge 8. The hinge 8 is formed of rubber, elastomer, spring-shaped metal, or the like. The lid 9 is made of polyethylene as an example, and the hinge 8 is integrally formed with the lid 9 and the base body 3 by insert molding. The hinge 8 may be provided by adhesion or fusion. When the hinge 8 is made of metal, a leaf spring or a coil spring is used, and both ends thereof are insert-molded. When a leaf spring is used, the central part is thin and narrow.

Reference numeral 11 is an inner cylinder, 12 is an engaging portion, and 13 is a locking portion. Since the hinge 8 is formed of rubber or another elastic body, when the lid 9 is opened, it stays in the open position when the container is tilted and the contents are poured out, and the hinge 8 hangs down. There is no such thing.

In this embodiment, the base body 3 is made of polyethylene and the opening wall 4 has the fissures 5. However, this is an example, and the present invention is not limited to this. It does not matter as long as the resin lid 9 is provided via the hinge 8, and all such lids are included. That is, it may have an inner lid shape as in the embodiment, or may be another container or the like. In addition, it does not matter if this part does not have the anti-fogging mechanism as described above.

The lid 9 is formed of polyethylene, or polypropylene in another embodiment, that is, formed in two ways. These have sufficient hardness, and the engaging portion 12 is hard by the engaging portion 13 and can be retained without loosening even when opening and closing a large number of times.

The operation of this embodiment is almost the same as that of the first embodiment except that the tear groove 5 is cut by using the tear member 7 to form an opening therein in the first use. Since it is the same as the operation of the present invention, it is omitted.

[0017]

[Effect of device]

 This hinge cap is configured as described above, and since the hinge 8 is made of an elastic body made of a material different from that of both the base body 3 and the lid body 9, as an example of the base body 3, As shown, even if a material such as a fissure is formed to facilitate tearing, or if, for example, the lid 9 is formed with a relatively hard locking portion that is tightly engaged with the main body 3, these functions will be maintained. You can get the job done. Moreover, the hinge 8 has a strong bending resistance, works well against a large number of times of elastic bending, and does not easily break.
