[Industrial applications]

 The present invention relates to a plastic cap, and more particularly to a plastic cap that has a spout and a lid that are inclined in the pouring direction and that can be manufactured with a single-shot molding die.

[0002]

[Prior art]

 Generally, when the bottle is made of an elastic material such as plastic and the content is a liquid, a plastic cap with a spout attached to the bottle has a structure as shown in FIGS. 5 and 6. ing. This plastic cap with a spout is composed of a cap body 1 and a canopy 2. The cap body 1 is composed of a tubular portion 3 and a sealing wall portion 4, and is configured to cover the entire mouth portion of the bottle body 5 as a whole. Then, a canopy 2 is continuously provided on the outer upper portion of the tubular portion 3 of the cap body 1 via a hinge portion 6. The canopy 2 has a dome shape that covers the entire upper portion of the cap body 1.

Inside the tubular portion 3 of the cap body 1, a female screw that is screwed into a male screw on the outer periphery of the mouth of the bottle body 5 is formed. A cylindrical spout 7 is formed in the center of the sealing wall 4 of the cap body 1, and the spout 7 is oriented perpendicular to the bottom surface of the bottle. An inner stopper 8 is provided at the center of the inner surface of the canopy 2 at a position where the canopy 2 is fitted into the spout 7 when the canopy 2 is closed. The inner plug 8 can be sealed so that the contents do not spill when fitted into the spout 7, and when the canopy 2 is opened, the inner plug 8 and the spout 7 can be easily removed. Is configured. In this plastic cap with a spout, the canopy 2 is attached to the cap body 1 via the hinge portion 6, and the cap can be manufactured by a one-shot molding die.

In order to pour out the liquid of the content from the bottle with the plastic cap with such a spout, as shown in FIGS. 7 and 8, the bottle main body 5 is tilted and the side surface of the bottle main body 5 is pushed to remove the liquid. Apply pressure to the area. At this time, if the amount of contents is large, it can be poured out even if the angle of inclination is small as shown in Fig. 7, but if the pushing method is weak, there is the inconvenience that the liquid will drop through the spout 7, and the pushing method will If it is strong, there is an inconvenience that the liquid is scattered. Therefore, as shown in FIG. 8, the bottle body 5 must be tilted at least until the spout 7 faces downward from the horizontal plane. However, when the amount of liquid in the bottle is large, the pressure of the liquid on the spout 7 is high, so even if the side surface of the bottle body 5 is pressed with a small force, a large force is applied to the spout 7 and a large amount of liquid is generated. It will be poured out. As described above, the conventional plastic cap having the spout has a drawback that it is difficult to finely adjust the spout amount.

In order to remedy the above-mentioned drawbacks, as shown in FIG. 9, there is provided a plastic cap in which the spout 7 itself has an appropriate length and is inclined. When such a plastic cap is used, as shown in FIG. 10, the spout 7 of the cap body 1 faces downward from the horizontal plane even if the bottle body 5 has a small inclination. Therefore, when pouring out the liquid of the contents, a light inclination is sufficient as shown in FIG. 10, so the pressure of the liquid applied to the pouring outlet 7 is not applied, and the pouring by the force pushing the side surface of the bottle body 5 is performed. It is easy to fine-tune the output.

[0006]

[Problems to be solved by the device]

 However, when the spout 7 having an appropriate length is inclined as shown in FIG. 9, there are the following inconveniences. That is, when fitting the inner plug 8 into the spout 7, the canopy 2 is rotated around the hinge portion 6 to move to the position of the slanted spout 7, but this movement trajectory becomes complicated. However, it is difficult to manufacture a plastic cap in which the canopy 2 and the cap body 1 are integrated with a single-shot molding die. Therefore, in the case of the plastic cap having the inclined spout 7, the canopy 2 with the inner plug 8 is manufactured as a separate part.

The present invention has been made in view of the above circumstances, and is a plastic cap having a cap body having an inclined spout and a canopy provided with an inner plug for sealing the spout. The purpose is to provide a plastic cap that can be manufactured with a casting mold.

[0008]

[Means for Solving the Problems]

 The plastic cap of the present invention for solving the above-mentioned problems is a cap body provided with a spout having an inclination in the spout direction, and a spout provided with an inner plug for sealing the spout. In a plastic cap having a canopy covering the whole, a band portion is provided from a base end of the cap body via a hinge portion, and the canopy is provided at a tip end of the band portion via a hinge portion, A groove for fitting the band portion is formed on the upper surface of the cap body excluding the portion covered with the canopy.
