DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hinge cap comprising a cap body which is assembled to a mouthpiece of a bottle and has a spout for content liquid, and a lid body for opening and closing the cap body is hinged. It is about.

[0002]

2. Description of the Related Art For example, a hinge cap of this kind which is tightly assembled to a mouthpiece of a bottle containing a contents liquid such as a dressing or a noodle soup is usually provided with a discharge pipe forming a discharge port of the contents liquid, or A fitting tube is erected on the cap main body at the peripheral end of the upper surface of the top wall where the spout is opened, and on the inner surface of the top wall of the lid hinged to the cap main body, the spouting tube or the fitting tube of the cap main body is attached. It is configured by hanging down a straight cylindrical plug piece that fits in and out to open and close the spout.

In this type of hinge cap, depending on the type of the content liquid, when the content liquid is poured, the bottle is shaken with the lid closed, and the content liquid is thoroughly stirred and then discharged. Because of the necessity, it is required that tight fitting of the stopper piece into the ejection cylinder or the fitting cylinder of the cap body be strong and reliable.

[0004]

However, in the above-mentioned prior art, since the opening and closing operation of the lid is a rotation operation about the hinge as a rotation axis, the opening and closing operation of the linear cylindrical lid is not possible. It is structurally difficult to exert a strong seal between the stopper piece and the cap body side part, and if a strong seal can be exhibited, the closed position of the lid becomes unstable, However, there is a problem that if the closing posture of the lid is stable, the sealing performance is unsatisfactory.

Further, when the bottle is shaken with the lid closed and the liquid content is thoroughly stirred and then poured out, the liquid attached to the lid drips, and the cap, the container and the surroundings are dripped off. There was a problem of getting dirty.

Accordingly, the present invention has been made to solve the above-mentioned problems in the prior art, and makes it easy to tightly fit the sealing function portion on the cap body side with the sealing function portion on the lid body. In the open position, the technical problem is to stop the downward movement that causes the liquid attached to the lid to drips, thereby obtaining a strong and reliable sealing of the cap body by the lid and the liquid from the lid. It is intended to obtain a good use state without dripping.

[0007]

Means for Solving the Problems Among the present invention for solving the above technical problems, the means according to the first aspect of the present invention is closely assembled to a bottle cylinder and has an upper surface of a top wall for opening a spout. At the periphery,
There is a cap body provided with a short tubular fitting cylinder having an undercut coupling function part on the outer peripheral surface, and a tapered tubular piece that stands up while reducing the diameter diagonally inward and upward at the upper end of this fitting cylinder. That is, the rear end of the cap body is integrally connected to the rear end of the cap body by a hinge. Another feature of the present invention is that it has a top-shaped cylindrical lid body provided with a stopper tube piece that fits tightly into the tapered cylinder piece of the cap body in the closed state, and is a synthetic resin integrally molded product.

In the closed position of the hinge cap, the peripheral cylinder of the lid body is externally fitted to the fitting cylinder of the cap body and is undercut-coupled, thereby maintaining the closed position of the hinge cap and the tapered cylindrical piece of the cap body. The plug piece of the lid is closely fitted in the cap body, and the cap body is sealed and held.

The stopper piece of the lid has a tapered tubular shape whose diameter is reduced downward, so that it is easy to fit into the tapered piece of the cap body. Since the opening edge of the tapered cylindrical piece can be made to be tight, the sealing of the cap body by the lid is firmly and reliably achieved.

By shaking the bottle and stirring the contents,
When the liquid content adheres to the inner surface of the top plate of the lid, the lid is opened, and the bottle is tilted to take out the liquid content when the liquid content is poured out. However, the adhered content liquid that has flowed down is blocked by the stopper piece of the lid, and dripping is prevented.

[0011] The function of preventing the attached liquid from dripping by the stopper piece of the lid is that the opening angle of the lid is 90 degrees or less because the wall of the stopper piece is inclined obliquely inward and downward. The dripping from the lid in the open position is almost completely prevented.

According to a second aspect of the present invention, in addition to the configuration of the first aspect, at least one of the tapered tubular piece of the cap body and the stopper tubular piece of the lid is made thin. is there.

According to the second aspect of the present invention, when the stopper barrel piece of the lid is fitted into the tapered barrel piece of the cap body, and at least one of them abuts, at least one is thin and elastically deformed. Since the close contact is easy to achieve, the tapered tube piece and the stopper tube piece are surely in close contact with each other, exhibiting high sealing performance, and in particular, the taper that brings the opening edge into contact with the outer peripheral surface of the stopper tube piece When the tubular piece is made thin, the opening edge is easily elastically deformed, so that a strong and stable sealing property can be reliably obtained.

According to a third aspect of the present invention, in addition to the configuration of the first aspect of the present invention, the inner surface of the top plate of the lid is formed as an inclined inner surface which is inclined downward in the circumferential direction.

In the third aspect of the present invention, when the lid is in the closed position, the liquid adhered to the inclined inner surface, which is the inner surface of the top plate of the lid, is placed on the peripheral end according to the inclination of the inclined inner surface. Since the liquid immediately flows down to the barrel and drops from the stopper barrel into the tapered barrel, that is, into the bottle, the liquid content does not adhere to and remain on the lid.

According to a fourth aspect of the present invention, in the configuration of the first aspect, a bottomed cylindrical pouring tube piece is erected inside the fitting tube on the top wall of the cap body. On the bottom wall of the outlet cylinder piece, a plugging portion is defined by providing a thin break groove in a closed loop shape, and a pull ring is integrally connected to an upper end portion of a connecting piece erected from one end of the upper surface of the plugging portion. It is a thing that added.

In the invention according to the fourth aspect, since the cap body has a cap structure with an unplugging portion, it is possible to obtain a stable and high sealing property of the bottle before unplugging, that is, before opening and using. Since the dispensing cylinder piece for satisfactorily dispensing the liquid is provided, the tapered cylinder piece having a structure that is not suitable for dispensing the content liquid does not have to act on the dispensing of the content liquid. Dispensing is stable and good.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. The hinge cap 1 is composed of a cap body 2 that is tightly assembled to a bottle body 22 and a lid body 15 that is connected to the rear end of the cap body 2 via a hinge 21. It is molded integrally with resin.

The cap body 2 has a lid 1 on the upper end of the assembled cylinder 3 which is fitted to the bottle mouth cylinder 22 and is undercut and connected thereto.
5, an inner flange-shaped top wall 4 having an upright fitting tube 13 which is fitted to the outer cylinder 18 and lightly undercut-coupled is continuously provided. The seal tube 12 is provided upright, and the seal tube 12 that fits tightly into the bottle mouth tube 22 is provided vertically below the top wall 4.

The pouring cylinder piece 5 whose upper end is expanded like a trumpet is
The rear side portion has a bottomed cylindrical shape that is open, and a closed loop-shaped breaking groove 9 is formed in the bottom wall 6 that closes the lower end of the pouring tube piece 5.
A plug ring 7 is sectioned and formed, and a pull ring 10 is connected to an upper end portion of a connecting piece 11 erected at the rear end of the upper surface of the plug removal portion 7.

At the upper end of the fitting tube 13, a thin tapered tube piece 14, which extends while reducing the diameter diagonally inward and upward, is continuously provided in an extended form of the fitting tube 13. 14 constitutes a seal portion on the cap body 2 side with respect to the lid 15.

The lid 15 is formed in a top-end cylindrical shape by connecting a top plate 16 to an upper end of a peripheral cylinder 18 having a finger hook 20 projecting from the lower end of the front end of the outer peripheral surface. In this portion, a stopper piece 19 is provided which is suspended while reducing its diameter diagonally inward and downward, and this stopper piece 19 constitutes a seal portion on the lid 15 side with respect to the cap body 2.

The inclined inner surface 17 which is the inner surface of the top plate 16
Is inclined downward toward a desired peripheral end portion, but in the case of the illustrated embodiment, it has a spherical arc-shaped surface with the central portion positioned at the highest position, thereby attaching to the inclined inner surface 17. When the lid 15 is in the closed state, the content liquid flows down toward the stopper piece 19 at the peripheral end according to the inclination of the inclined inner surface 17.

In the case of the illustrated embodiment, the angle of inclination (the angle on the acute angle side) of the tapered tube piece 14 and the stopper tube piece 19 with respect to the vertical direction is both about 35 degrees.
In the state where the opening angle of No. 5 is 55 degrees or less, the function of blocking the stopper piece 19 against the content liquid attached to the inclined inner surface 17 disappears. Does not stop at an angle of 55 degrees or less, so that no dripping occurs here.

Since the lower surface of the stopper 7 of the cap body 2 is simply an inclined lower surface 8 inclined in a certain direction, the liquid attached to the inclined lower surface 8 quickly flows down and disappears. Thereby, when the plug removal portion 7 is broken and removed, splashing of the content liquid is prevented from occurring due to the impact of the break removal.

[0026]

Since the present invention has the above-described structure, the following effects can be obtained. According to the first aspect of the present invention, the stopper piece of the lid is securely fitted into the tapered barrel piece of the cap body in the closed posture, and the fitting allows the outer periphery of the stopper piece of the lid to be fitted. The close contact of the opening edge of the tapered tube piece of the cap body with the surface is firmly and reliably achieved, whereby the sealing of the cap body by the lid can be reliably, firmly and stably achieved.

When the lid is in the open position, the flow of the liquid content adhering to the lid is reliably blocked by the stopper piece. Since the liquid is reliably exerted until the inclination angle becomes 90 degrees or less, the dripping of the liquid attached to the lid can be reliably prevented, whereby a hygienic and favorable use state can be obtained.

According to the second aspect of the present invention, a close contact between the tapered tubular piece of the cap body and the stopper tubular piece of the lid body can be reliably obtained. Obtainable.

According to the third aspect of the present invention, the content liquid attached to the inner surface of the top plate of the lid can be quickly flowed down into the bottle, so that a large amount of the content liquid adheres to the lid. Thus, the occurrence of dripping from the lid can be almost completely eliminated.

[0030] In the invention according to claim 4, before plugging,
In other words, it is possible to obtain a stable and high sealing property of the bottle before opening and use a pouring cylinder piece for satisfactorily pouring the content liquid, so that the structure is not suitable for discharging the content liquid. The tapered tube piece does not have to act on the discharge of the content liquid, so that the discharge state of the content liquid does not deteriorate.
