DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mouth structure of a container such as a bottle, a plastic container or a can, and a container stopper.

[0002]

2. Description of the Related Art Conventionally, the mouth structure of a container fixed to the mouth of a plastic bottle, a glass bottle, or the like, and a container stopper are provided with a stopper formed separately from the container. What is fixed to a part is known. In this plug, a flat plate portion for preventing leakage of the liquid inside the container is formed in a cylindrical outer frame portion to be fixed, and an opening forming portion defined by a groove for breaking is provided in the flat plate portion, In some cases, a ring-shaped handle is protruded from the opening forming portion, and a lid for closing the spout is provided around the flat plate portion.

[0003] A "liquid pouring plug" disclosed in Japanese Utility Model Laid-Open Publication No. 3-72655 has a "top plate portion which is in close contact with the top surface of a container mouth portion, In an inner plug having an ejection cylinder and an inner cylinder part inserted into the container mouth on the lower surface of the top plate part, a large number of thin plate-shaped fins protrude from the inner periphery of the inner cylinder part toward the center of the inner stopper. A thin plate having a joint upper end position of the fin and the inner cylinder portion in each fin shifted horizontally with respect to a joint lower end position of the fin, and a joint portion of each fin inclined with respect to a vertical axis. Fins are formed integrally with the inner cylinder portion in the inner cylinder portion. "

[0004]

It is known that when a new bottle containing sufficient contents is opened and tilted, a pulsating flow is generated in the contents flowing from the plug of the bottle. This is presumably because the negative pressure inside the bottle increases as the amount of outflow of the contents increases, so that the air outside the bottle enters the inside of the bottle against the liquid flowing out of the bottle.

[0005] In the case of a conventional small bottle of about 500 ml which is used only by opening a spout in a flat plate portion, the pulsating flow is not so conspicuous because the capacity is relatively small, but 1
In the case of large bottles and plastic tanks of 000 ml or more, a large amount of contents will come out even with a slight tilt,
The pulsating flow is also likely to be large, and the outflow direction of the contents is unstable and the flow speed is also unstable, so the contents spill from the receiving container, the contents splash from the mouth, or flow out more than necessary It is difficult to adjust the flow rate and outflow direction.

In the "Liquid pouring spout" of Japanese Utility Model Laid-Open No. 3-72655, the fins projecting inward from the inner cylinder are inclined with respect to the vertical line, so that when the mouth of the bottle is turned upside down, A vortex is generated in the liquid coming out of the bottle, which makes it easier to discharge the liquid quickly.However, there is only one opening in the inner cylinder of the plug, and there is no air flow path. When the liquid is taken out, a pulsating flow is also likely to occur. In addition,
In the case where an air flow path is provided, there is a problem that attention must be paid to how to pour the air since the direction in which the container is inclined is determined.

The mouth structure of the container and the stopper for the container according to the present invention focus on such problems, and in particular, bottles, tanks, cans made of plastic or glass having an inner diameter of about 10 to 35 mm, etc. Even when used in a container mouth structure that closes the mouth of a box, package, or other large-capacity container, do not spill the contents or discharge more than necessary when discharging the contents from the mouth of the container. Another object of the present invention is to provide a container mouth structure and a container plug capable of adjusting the flow rate of the contents while minimizing generation of a pulsating flow.

[0008]

C is assembled.

After the assembly of the plug C is completed, the container body 1 is filled with the contents and the plug C is fixed to the container body 1, whereby the mouth portion 2 of the container body 1 can be sealed. At the time of opening, it is possible to reduce the pulsating flow when the container body 1 is poured out, and to adjust the directionality and the flow rate stability.

According to the container plug and the container mouth structure of the present embodiment, the resistance plate 6 of the mouth 2 receives the large flow rate and liquid pressure of the liquid at the time of pouring, and is opened radially. The flow direction of the content liquid can be dispersed and bypassed through the six outlets 6. Therefore, for example, it is particularly effective for liquids such as shochu, soy sauce, Worcester sauce, etc., which have low viscosity and flow easily.

Further, six outlets 7 are opened in the resistance plate portion 6, and the outlet 7 is always located at a position above the mouth 2 where the liquid pressure is weak, regardless of the direction in which the container is inclined. Since each spout 7 is defined by an independent pouring path 8 formed by the defining wall portion 9 and the small-diameter cylindrical portion 14, even if a new container filled with the contents is opened and tilted, air is introduced. A route is secured, and air is easily introduced into the inside.

Therefore, the pulsating flow at the time of discharging the liquid of the contents is attenuated, and the flow direction, the flow rate and the fluctuation amount of the liquid at the time of the discharging can be stabilized, and the droplets of the content liquid are hard to fly. . In addition, if the area of the resistance plate portion is increased, even highly viscous contents such as oil and sauce are suitable. The spout can be adjusted by increasing the viscosity as the viscosity increases and decreasing the viscosity when the viscosity is low.

Furthermore, according to the container plug of this embodiment,
In addition to the functions and effects of the mouth structure of the container, each of the fixed frame portion 3, the inner plug 5, and the lid 4 is configured separately from the container body 1, so that molding is easy and the fixed frame When the inner plug 5 is fitted to the portion 3 and the lid 4 is fixed to the outside of the fixed frame portion 3, the plug C can be easily assembled.
