[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a two-liquid mixing container in which different kinds of preparations are stored separately and mixed when used.

[0002]

2. Description of the Related Art Many such mixing vessels have been proposed and are well known. Japanese Utility Model Application Laid-Open No. 58-55031 is one such example.

In this publication, an opening is provided in the lower container body of the first liquid storage at the center of the bottom wall, and the opening is sealed from below with an inner stopper. Are stacked by screwing the lower part of the body to the mouth and neck of the lower container body, and as the inner plug, an inverted tray-shaped plug inserted from the inner peripheral edge of the donut-shaped substrate into the bottom opening. The body is erected, and a double peripheral wall that sandwiches the mouth and neck of the lower container body is suspended from the outer peripheral edge, and a through hole is formed in the peripheral direction of the substrate. At the time of mixing, the upper container body is screwed upward, and a space is formed around the plug body of the inner plug by this screwing, and the second liquid in the upper container body flows down from the gap through the through hole to the lower container body, It is to be mixed.

[0004]

In this kind of container, the liquid tightness between the outside air to prevent deterioration of the filling liquid and the liquid tightness between the containers to keep the two liquids isolated until mixing. Is important.

In the above conventional example, the seal of the first liquid in the lower container body is formed by bonding the top surface of the mouth and neck to the back surface of the peripheral portion of the substrate, and the seal for separating the two liquids is formed in the center of the bottom wall of the upper container body. The connection is made around the opening and around the plug of the inner plug inserted into the opening.

[0006] The joining for these seals is performed by screwing when screwing and stacking the upper and lower container bodies. This screwing is performed between the body of the upper container body and the mouth and neck of the lower container body. Because of the peripheral edge of the container, the seal on the top of the mouth and neck can be expected to be sufficiently sealed because the tightening by screwing works strongly, but the seal for two liquid separation between the central opening at the bottom of the upper container and the stopper of the inner stopper is required. Since the container shaft portion is farthest from the screwed portion, there is a disadvantage that the tightening is insufficient and the seal tends to be insufficient.

The present invention provides a two-liquid mixing container in which a seal part for separating two liquids is disposed on a peripheral portion of the container where the tightening at the time of assembling acts strongly, and the sealing property of the seal part is improved as much as possible. There is to get.

[0008]

The two-liquid mixing container of the present invention comprises a lower container body 1 containing a first liquid and having a large-diameter mouth-and-neck portion 5 having a slightly reduced upper half portion 5a, and a disk-shaped container. Is a cap having a mounting wall 7 suspended from the peripheral edge of the plug plate 6, and through holes 8 are formed around the peripheral edge of the plug plate 6 in a circumferentially discrete manner.
An annular opening 9 communicating with the inside of the lower container body 1 is formed by the inner and outer double peripheral walls rising from the upper surface of the plug plate 6 so as to sandwich the stopper plate 6, and the opening and closing wall 7 closes the opening of the lower container body 1 via the first packing 10. Inner plug 2 attached to upper half 5a of part 5
And a lower part 11a made of a material having a hardness different from that of the inner plug 2.
Is partially screwed into the outer surface of the lower half portion 5b of the mouth and neck portion 5b of the lower container body 1 and extends upward, and is fitted in the annular opening 9 from the inner surface of the intermediate portion via an inward flange 12 to seal it. An intermediate cylindrical member 3 in which a downward U-shaped annular plug 13 is vertically provided and a second packing 14 is disposed on the upper surface of the inward flange 12, and a lower portion of the body 15 is screwed into an inner surface of an upper portion 11b of the intermediate cylindrical member 3. At the same time, the second packing 14 is pressed against the lower end of the body 15 to seal the inside of the second packing 14 and is stacked above the lower container 1, and the upper opening of the second liquid container 4 whose upper opening is closed by the nozzle cap 16.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a sectional view of a mixing container according to the present invention; FIG. The main member is formed by molding and manufacturing a synthetic resin material.

First Embodiment (FIGS. 1 and 2) The lower container body 1 has a large-diameter mouth and neck portion 5, which has a thread formed on the outer surface of a lower half portion 5b. The upper half 5a is slightly reduced in diameter and is provided with an engaging ridge 18 on its outer surface.

The inner plug 2 is a cap-shaped one in which a mounting peripheral wall 7 having an engaging ridge 18 protruding from a peripheral edge of a disk-shaped plug plate 6 having a recessed central portion is formed on the lower inner surface. 7 is fitted to the outer surface of the upper half 5a of the mouth and neck portion 5,
The opening 18 is engaged with and fixed to the engaging ridge 17 to close the opening 5 of the lower neck 1. In this case, the first mouth and neck
The packing 10 is disposed, and the packing 10 is pressed by the stopper plate 6 to seal the inside of the lower container 1.

The inner plug 2 also has several through-holes 8 around the periphery of the plug plate 6 at discrete intervals in the circumferential direction, and raises the inner and outer double peripheral walls from the upper surface near the periphery so as to sandwich these through-holes 8. Thus, an annular opening 9 is formed on the upper surface of the peripheral portion, and the annular opening 9 is passed through the through hole 8 into the lower container 1.
In the figure, reference numeral 19 denotes a stopper, and reference numeral 20 denotes a guide peripheral wall. The inner plug 2 is made of a deformable, somewhat soft synthetic resin material.

The intermediate cylindrical member 3 is formed of a hard synthetic resin material which is harder than the inner plug 2 and has a lower portion 11a and an upper portion 11a.
A thread groove is formed on the inner surface of each of the inner portions 11b, and an annular stopper 13 having a U-shaped cross section is partially projecting inward from an inner surface of the intermediate portion through an inward flange 12, and a lower portion 11a is formed by The lower half 5b is screwed onto the outer surface and the inward flange 12
The second packing 14 is disposed on the upper surface.

When the intermediate cylindrical member 3 is screwed onto the outer surface of the lower half 5b of the mouth and neck portion 5 of the lower container body 1, an annular stopper descending into the same body is forcibly pushed into the annular opening 9 and is fitted therein. The opening 9, and thus the through hole 8, is closed and both container bodies 1,
Seal between the four, that is, isolate two different liquids. Since the double peripheral wall for forming the annular opening 9 and the annular plug 13 have different hardnesses, when the annular plug 13 is forcibly pushed into the annular opening 9 to be fitted therein, the soft annular opening 9 side is deformed to form the annular plug 13. As it adheres to the surface, it can be sealed without packing. 21 is a guide peripheral wall, and 23 is a stopper.

The upper container body 4 has a thinner and squeezable squeeze-shaped body 15 and a lower part 15a formed as a thick part is slightly reduced in diameter, and a thread is formed on the outer surface of the reduced diameter lower body 15a to form a bottom part. It is opened, and a nozzle-shaped cap 16 having a small-diameter tip opening is screwed and attached to the upper mouth and neck 23, and an upper cap 24 is screwed to the outer surface of the first half of the nozzle-shaped cap 16 to open the tip opening. The lower body 15a is screwed onto the inner surface of the upper part 11b of the intermediate tubular member 3 and is stacked above the lower container body 1. At this time, the second packing 14
To seal the inside of the upper container body 4. The second liquid is filled from the mouth and neck 23 before the nozzle cap 16 is attached.

In the figure, reference numeral 25 denotes a ratchet mechanism formed between the inner surface of the upper end of the intermediate tubular member 3 and the outer surface of the upper end of the lower body 15a. This prevents the upper container body 4 from coming off the intermediate cylindrical member 3 due to the reverse rotation.

Reference numerals 26 and 27 denote the intermediate cylindrical member 3 and the lower container body 1.
And lowering the lower container body 1 downwardly from the intermediate cylindrical member 3 during mixing as shown in FIG.
Engage when both screws are loosened and separated by a predetermined distance,
Both are prevented from coming off. This is because, if inadvertently performed during mixing, the lower container body 1 may come off the intermediate cylindrical member 3 and leak the mixed liquid to the outside.

According to this embodiment, the assembly of the container is performed by screwing the threaded portion of the peripheral edge. An opening 9 for communicating between the two container bodies 1 and 4 is formed as an annular shape near the periphery, and an annular stopper 13 which is fitted and closed in the annular opening 9 to seal between the container bodies 1 and 4 has the same peripheral arrangement. Since the tightening force at the time of screwing is made to act almost equally as strongly as the peripheral portion of the container, and the hardness of the annular opening 9 and the annular plug 13 is made different, and at the time of internal fitting and closing, one of them is deformed and brought into close contact. Sealing can be reliably performed without using packing, and the sealing performance of two-liquid separation is improved.

The liquid mixing is performed by screwing the lower container 1 downward until the engaging ridges 26 and 27 abut, as shown in FIG. 2, and opening the annular opening 9 of the inner plug 2. To pour out the mixture, invert the container, squeeze the body 15 and
It may be poured out from the small-diameter opening at 16 tips.

Second Embodiment (FIG. 3) In this embodiment, the length of the intermediate cylinder member 3 is shortened, and thus the length of the entire container is shortened. Are formed to rise upward from the inner peripheral edge of the inward flange 12. In this example, if the length of the container body is not changed, the squeeze portion of the body 15 of the upper container body 4 can be lengthened accordingly, and usability such as squeezing operation is improved.

In each of the above embodiments, the hardness of the inner lid 2 is set to be softer than the hardness of the intermediate cylindrical member. However, the relationship may be reversed. The upper container 4 is not limited to the squeeze shape.

[0028]

As described above, according to the present invention, the upper and lower container bodies 1 and 4 filled with different kinds of liquid are vertically stacked by screwing the peripheral portions through the intermediate cylindrical member 3 and the lower container body 1 port is provided. Sealing between the two container bodies 1 and 4 with the inner plug 2 attached to the top 2
In the liquid mixing container, the inner stopper 2 and the intermediate cylindrical member 3 are formed of materials having different hardnesses, and the opening 9 for communication between the two container bodies 1 and 4 at the time of mixing formed in the inner stopper 2 is arranged in an annular shape near the periphery. The annular opening 9 is configured such that the annular plug 13 integral with the cylindrical member 3 is internally fitted and closed by screwing the intermediate cylindrical member 3 which is screwed and mounted at the time of assembling. The inner container 9 can be closed and closed, and in this case, one can be deformed so that it can be closely contacted. Therefore, it is possible to seal the two container bodies 1 and 4 in a substantially completely sealed state without using a packing at all times, and the sealing property is improved. .
