Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container for storing a liquid, which has a function of preventing a pulsating flow and controlling a discharge amount when discharging an internal liquid.

[0002]

2. Description of the Related Art Conventionally, as this type of container, there are a two-port container shown in FIG. 16 and a container having an air supply mechanism shown in FIG.

[0003]

In the two-port container shown in FIG. 16, it is troublesome to open both caps in order to rectify and discharge the internal liquid. In addition, the two-port type has a factor in cost increase such as the production of containers and the need for two caps. In contrast, a container of the type shown in FIG.
Since it is a mouth, it is easy to use, but the handle must be used as an air supply pipe, and there are restrictions on the container design.

Further, a feature common to these containers is that air supplied into the container is directly introduced into the container without passing through the internal liquid. With this type of mechanism, extremely smooth discharge is possible, but the discharge speed changes in proportion to the height of the internal liquid. That is, the discharge speed is high in the initial stage when the internal liquid amount is large, but decreases as the internal liquid amount decreases. For this reason, it is necessary to control the discharge speed by adjusting the angle of the container according to the amount of the internal liquid.

[0005]

According to a first aspect of the present invention, a blow molding section 13 is provided below the container mouth 11 to form a shape by a blow pressure at an opening larger than the upper mouth, and the body is narrowed down. In this way, the discharge port 2 is
1 and an air port 22 are formed.

According to a second aspect, the air port formed in the first aspect is extended to extend the air tube.
It is set to 1. This can prevent a burping phenomenon at the time of discharging (a phenomenon in which, when discharging is stopped halfway, the container returns to an upright state, but the internal liquid partially jumps out of the container opening).

According to a third aspect of the present invention, the discharge port 21 is provided substantially coaxially with the container opening 11 and in substantially the same size and shape.

[0008]

Embodiment 1 FIG. 1 is a front view, a side view, and a plan view of Embodiment 1, FIG. 2 is an enlarged sectional view of a mouth portion, FIG. 3 is a sectional view taken along the line AA in FIG.
Is a sectional view taken along the line BB in FIG. 2, and FIG. 5 is a sectional view taken along the line CC. FIG. 6 is an enlarged cross-sectional view of a mouth showing a discharge state in the container of the first embodiment. This embodiment is an example of claims 1 and 3. With such a configuration of the container opening, replacement of the discharged liquid and the intake air can be performed smoothly at one opening.

In this example, the discharge port 21 formed in the narrowing section 14 is provided coaxially with the container port section 11;
By moving the air port 1 and the air port 22 as a set to the left in the drawing, the size of the blow molding section 13 can be made more compact. Further, although the discharge port is circular, it is not always necessary to have a circular shape, and it is possible to make the discharge port into a fan shape so as to make it compact. However, in this case, it is expected that an inconvenience will occur when an inner liquid filling nozzle or pumps are inserted into the container mouth.

This mechanism is a compact suction mechanism in contrast to a large-scale suction mechanism using a handle as shown in FIG. 17, so that it can be applied to more types of containers. In addition, the air supplied into the container is configured to pass through the internal liquid, and in this type of mechanism, the discharge speed is almost constant regardless of the internal liquid amount. For this reason, in the conventional container, the discharge speed changed depending on the internal liquid volume,
Although the discharge speed was controlled by adjusting the container angle, such an adjustment is not required in the present mechanism container.

Embodiment 2 FIG. 7 is a front view, a side view, and a plan view of Embodiment 2, FIG. 8 is an enlarged sectional view of the mouth, FIG. 9 is an EE sectional view in FIG. 8, and FIG. FIG. 11 is a sectional view taken along line FF in FIG. 7, and FIG. 11 is a sectional view taken along line DD in FIG. This embodiment is an example of the second aspect. By extending the air port 22 to form the air tube 81, the burping phenomenon (discussed above) at the time of ejection is prevented, and smooth ejection is enabled.

Further, in this example, the discharge port 21 is formed into a sector shape to reduce the size of the blow molding section 13.
For this reason, a bulge due to the squeezing portion 14 is present in the container mouth, which may cause inconvenience when the filling nozzle is inserted or the pump is used. On the other hand, because of this compactness, it is possible to use not only a flat rectangular container as shown in the figure but also a round container.

Third Embodiment FIG. 12 is a front view, a side view, and a part of a plan view of a third embodiment. FIG. 13 is an enlarged sectional view of a container mouth portion, and FIG.
FIG. 3 is a sectional view taken along line GG in FIG. FIG. 15 is an enlarged cross-sectional view of the mouth showing the discharge state of the container of the third embodiment. This embodiment is an example of claims 2 and 3.

In this embodiment, the air port 22 of the first embodiment is extended to form an air tube 81 as in the second embodiment. By doing so, the rectifying action becomes smoother, and the space between the discharge port 21 and the air port 22 can be made closer to achieve a compact size. Furthermore, by applying Japanese Patent Application No. 2001-029345 of the present applicant to make the length of the air tube appropriate, it is possible to obtain a substantially constant discharge speed even when the discharge angle changes. You can also.

[0015]

【The invention's effect】

(1) Rectifying discharge in a one-port container is enabled. (2) Since the discharge speed is kept substantially constant irrespective of the internal liquid amount, it is not necessary to control the discharge speed by changing the container angle according to the internal liquid amount unlike the conventional container. (3) Since the intake mechanism is compact, the degree of freedom in container design is large. (4) No special machine or device is required for molding, and molding can be performed by a conventional molding method.
