Abstract

(57) [Summary] [Purpose] In a conventional cap, a so-called anti-rapping mechanism generally uses two types of hinges having different lengths, and has a complicated structure. For this reason, the container cap which improves this and can perform the anti-skid action only with two hinges of one kind is provided. [Structure] An injection cylinder is provided on a top wall of a base body having a synthetic resin cylindrical portion to be mounted on a container, a lid body is integrally provided on the upper end portion of the cylindrical portion by two similar hinges, and each of the hinges is provided. A taper having an arcuate cross-section and increasing toward the tip was formed.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a container cap.

[0002]

[Prior art]

 Although it is not shown in the figure because it is well known in the past, when the lid is opened and the liquid content in the container is poured out, it is intended to prevent the opened lid from dropping down on the pouring outlet and blocking the pouring outlet. In addition, a so-called fogging prevention mechanism is used.

Although there are various types of this mechanism, usually two types of hinges having different lengths are used to prevent the above-mentioned fogging.

[0004]

[Problems to be solved by the device]

 However, it has the following drawbacks. That is, since the two hinges are formed with different lengths, the structure is complicated and the manufacturing is troublesome. The present invention has been made to solve such a problem, and its purpose is only a kind of hinge, and therefore, a cap of a container which has a very simple structure and is easy to manufacture and has a cap prevention mechanism. Is to provide.

[0005]

[Means for Solving the Problems]

 This invention which achieves the above-mentioned object will be described. It is a base body 3 to be mounted on a container, which has a cylindrical portion 1 made of synthetic resin to be mounted on the container, and a pouring cylinder 2 for pouring the liquid content of the container A lid 6 integrally provided on the upper end 4 of the tubular portion 1 of the base body 3 by two similar hinges 5 and 5; a taper 8 having an arcuate cross section and becoming larger toward the tip 7. A cap for a container, characterized in that it comprises the above-mentioned hinges 5, 5;

[0006]

The present invention is constructed as described above, and when the lid body 6 is opened and the lid body 6 is further rotated in the opening direction, the hinges 5 and 5 are arcuate in cross section and reach the tip end. Since the hinges 5 and 5 have large taper, the hinges 5 and 5 are inverted so that the outer sides thereof are slightly downward, so that the lid body is held in that state. Therefore, it is possible to prevent so-called fogging.

The number of the hinges 5 and 5 is only two, and since it is not necessary to provide the two types of hinges having different lengths as described in the conventional example, manufacturing can be made very easy. You can

【Example】

 In FIGS. 1 to 4, reference numeral 3 denotes a base body to be attached to a container, which has a tubular portion 1, a top wall 11 and a casting pipe 2. Two similar hinges 5 and 5 are provided on the upper end portion 4 of the tubular portion 1, whereby the lid body 6 is integrally provided. These are entirely made of one synthetic resin.

As for the hinges 5 and 5, as shown in FIG. 2, it has a taper 8 having an arcuate cross-section and becoming larger toward the tip end portion 7. Further, the inner surface thereof has a large number of protrusions 12 as shown in FIG. Due to the protrusion 12, the rotation has a good reversal property, and it operates smoothly and energetically. In addition, 13 is a solid stop portion, 14 is a cylindrical body that closes the injection cylinder 2, and 15 is a thread, which is screwed into the container.

Although illustration is omitted, instead of the above-mentioned pouring tube 2, a pouring tube is provided concentrically on the top wall 11, and an endless fissure is formed inside the pouring tube to form a tearing portion. However, a pull ring or the like may be provided on the upper surface of the tear portion.

Further, 16 is a flat portion, and the hinges 5 and 5 are formed on both sides of the flat portion 15, so that the protrusions are formed on the outer periphery to be extremely small, which facilitates the alignment during capping, and accordingly You can improve the speed of capping.

[0012]

[Effect of device]

 Since this invention is constructed as described above, the hinges 5 and 5 are different from the conventional ones, and only one type is required, and the structure can be simplified, and therefore the manufacturing can be facilitated.
