[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a two-liquid mixing container in which different kinds of preparations are isolated and stored, and these are mixed and used at the time of use.

[0002]

[Prior art]

 A large number of mixing containers of this type have been proposed and are well known. Japanese Utility Model Laid-Open No. 58-55031 is one such example.

According to this publication, an upper container for containing a second liquid, in which a lower container body for containing a first liquid is provided with an opening in a central portion of a bottom wall and the opening is sealed with an inner plug from below, is disclosed. The body is constructed by stacking the lower part of the body by screwing it into the mouth and neck of the lower container body, and as the inside plug, it is an upside down tray shape that is inserted into the bottom opening from the inner peripheral edge of the donut-shaped substrate. The structure in which the stopper body is erected, a double peripheral wall that holds the mouth and neck of the lower container body from the outer peripheral edge is hung, and through holes are opened in the circumferential direction of the substrate. At the time of mixing, the upper container body is screwed upward, and by this screwing, a gap is formed around the stopper body of the inner stopper, and the second liquid in the upper container body is passed through the through hole from this gap to the lower container body. It is made to flow down and mixed.

[0004]

[Problems to be solved by the device]

 In this type of container, it is important to have an airtight seal structure between the container and the outside air to prevent deterioration of the filling liquid, and a liquid-tight seal structure between the containers to keep two liquids separated until mixing.

In the above-mentioned conventional example, the first liquid seal of the lower container body is formed by joining the mouth neck top surface and the back surface of the peripheral edge of the substrate, and the seal separating the two liquids is formed in the central portion of the bottom wall of the upper container body. It is made by joining the circumference of the mouth and the circumference of the plug body of the inner plug fitted in this opening.

[0006] The joining for these seals is performed by screwing when the upper and lower container bodies are screwed and stacked, and this screwing is performed between the body of the upper container body and the mouth and neck of the lower container body. Since it is the peripheral edge of the container, the sealing of the mouth and neck top surface is strongly tightened by screwing, so a sufficient seal can be expected, but a seal for separating two liquids between the central opening at the bottom of the upper container and the stopper of the inner stopper is Since it is the core of the container that is farthest from the screw-in part, it has the drawback that it may not be sufficiently tightened and the seal may be insufficient.

The present invention provides a two-liquid mixing container in which a sealing part by packing is arranged in the peripheral part of the container where the tightening is the strongest, and particularly the sealing property for separating two liquids is improved as much as possible. is there.

[0008]

[Means for Solving the Problems]

 The two-liquid mixing container of the present invention comprises a lower container body 1 for containing a first liquid having a large diameter mouth / neck part 5 having a slightly reduced upper half part 5a, and the mouth / neck part 5 opening. 5 A peripheral wall 8 for fitting and fixing to the outer surface of the upper half 5a of the mouth / neck 5 is hung vertically from the peripheral edge of the stopper plate 7 which is sealed through the first packing 6 arranged at the top of the stopper plate 5 from the upper surface near the peripheral edge. An annular opening 9 is formed by the erected inner / outer double peripheral wall, and a stopper plate 7 at this annular opening 9 portion is provided with a circumferentially discrete communication hole 10 for communicating the annular opening 9 with the lower container body 1. 2 and the lower portion 11a are screwed to the outer surface of the lower half portion 5b of the mouth / neck portion 5 of the lower container body 1 and extend upward, and the annular opening 9 is second-packed from the inner surface of the intermediate portion through the inward flange 12. A donut-shaped inner lid 14 that seals via 13 is provided protruding, and a third packing 15 is arranged on the upper surface of the inward flange 12. The tubular member 3 and the lower portion of the body 16 are screwed onto the inner surface of the upper portion 11b of the intermediate tubular member 3, and the third packing 15 is pressed against the lower end of the body 16 to seal the inside and to be stacked above the lower container body 1. And an upper container body 4 for accommodating a second liquid whose upper opening is closed by a nozzle-like cap 17.

[0009]

[Action]

 In the above, the container is assembled by first filling the lower container body 1 with the first liquid, and then attaching the inner plug 2 to the upper neck portion 5a of the mouth / neck portion 5 of the lower container body 1 to open the mouth portion of the lower container body 1. And the inside of the lower container body 1 is sealed to the outside by pressing the first packing 6 under pressure.

Next, the lower portion 11a of the intermediate tubular member 3 is screwed onto the outer surface of the lower half portion 5b of the mouth / neck portion 5 of the lower container body 1, and by this screwing, the inner lid 14 is looped with the inner lid 14 through the second packing 13. The opening 9 is sealed, that is, the container bodies 1 and 4 are sealed.

After that, the lower part of the body 16 of the upper container body 4 is screwed into the inner surface of the upper part 11b of the intermediate tubular member 3, and at the end of this screwing, the third packing 15 is pressed against the lower end of the body 16 to form the upper container body. The inside of 4 is sealed to the outside, and finally the upper container body 4 is filled with the second liquid from the upper opening, and the upper opening is closed by the nozzle cap 17.

That is, the container is assembled by screwing the threaded portion on the peripheral edge, but the second packing 13 for sealing between the two container bodies 1 and 4 is arranged near the peripheral edge, and accordingly, the peripheral portion is sealed. Similar to the first and third packings 6 and 15 for external sealing of the container bodies 1 and 4 at the edge portions, a strong tightening force is applied, so that a sealing property close to a nearly perfect seal can be expected.

During liquid mixing, the lower container body 1 is screwed downward from the intermediate tubular member 3, and the container bodies 1 and 4 are communicated with each other through the annular opening 9 and the communication hole 10 of the inner plug 2 as shown in FIG. It should be in a state.

When the mixed liquid is poured out, the tip opening of the nozzle cap 17 is opened and the container is turned upside down. If the upper container body 4 is of the squeeze type, the body 16 is squeezed and poured out from the nozzle cap 17. Good.

[0015]

【Example】

 An embodiment will be described below with reference to the drawings. The mixing container of the present invention comprises a lower container body 1, an inner stopper 2, an intermediate cylinder member 3 and an upper container body 4 as main members.

First Embodiment (FIGS. 1 and 2)

The lower container body 1 has a large-diameter mouth / neck portion 5, which forms threads on the outer surface of the lower half portion 5b, and the upper half portion 5a has a slightly reduced diameter on the outer surface. The engaging protrusion 18 is provided so as to project.

The inner plug 2 is a cap-shaped one in which a mounting peripheral wall 8 having an engaging projection 19 projecting from the peripheral edge of a stopper plate 7 having a recessed central portion is provided on the inner surface of the lower part thereof. It is fitted on the outer surface of the upper half 5a of the mouth / neck portion 5, and at this time, the engaging ridge 19 is engaged and fixed to the engaging ridge 18 to close the mouth / neck 5 opening of the lower container body 1. In this case, the first packing 6 is arranged on the top of the mouth / neck portion 5, and the packing 6 is pressed by the stopper plate 7 to seal the inside of the lower container body 1.

The inner plug 2 also has inner and outer double peripheral walls standing upright from the upper surface near the peripheral edge of the stopper plate 7 to form an annular opening 9 on the upper surface of the peripheral edge portion. Several communication holes 10 are formed in the lower container body 1 and an annular opening 9 is made to communicate therewith. In the figure, 20 is an annulus and 21 is a guide peripheral wall.

The intermediate tubular member 3 has screw grooves formed on the inner surfaces of the lower portion 11a and the upper portion 11b, respectively, and a donut-shaped inner lid 14 having a U-shaped partial cross section inward from the inner surface of the intermediate portion through the inward flange 12. The lower portion 11a is screwed and attached to the outer surface of the lower half portion 5b of the mouth / neck portion 5.

A second packing 13 is arranged on the back surface of the inner lid 14, and a third packing 15 is arranged on the upper surface of the inward flange 12 so as to be fitted and attached to the mouth / neck portion 5 of the lower container body 1. At this time, the inner lid 14 presses the second packing 13 against the annular opening 9 to seal the annular opening 9 and thus the communication hole 10, and in other words, the container body 1 and 4 are separated, that is, the two different liquids are separated and sealed. To do. 22 is a reinforcing material and 23 is a ring stopper.

The upper container body 4 has a slightly squeezed squeeze-shaped body 16 having a thin thickness and a slightly reduced diameter, and a screw thread is formed on the outer surface of the reduced lower body 16a to open the bottom. In addition, a nozzle-shaped cap 17 with a small opening at the tip opening was screwed onto the upper neck / neck 24 at the top, and an upper cap 25 was screwed onto the front half of the nozzle-shaped cap 17 to close the tip opening. The lower body 16a is screwed onto the inner surface of the upper portion 11b of the intermediate tubular member 3 and is stacked above the lower container body 1. At this time, the third packing 15 is pressed at the lower end of the body 16 to form the upper portion. The inside of the container body 4 is sealed. The second liquid is filled from the mouth / neck portion 14 before attaching the nozzle cap 17.

In the figure, 26 is 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 corresponding lower body 16a. The ratchet mechanism 26 is used to mount the upper container body 4 so that it cannot rotate in the reverse direction. The reverse rotation prevents the upper container body 4 from coming off the intermediate tubular member 3.

Reference numerals 27 and 28 are engaging ridges for preventing the intermediate cylinder member 3 and the lower container body 1 from being separated from each other. As shown in FIG. 2, the lower container body 1 is screwed downward from the intermediate cylinder member 3 during mixing. They are retracted, and when they are loosened, they are engaged when they are separated by a predetermined distance to prevent them from coming off. This is because if carelessly taken during mixing, both 1 and 3 may be removed, and the mixed solution may leak to the outside. According to this embodiment, the assembling of the container is performed by screwing the threaded portion on the peripheral edge, but both container bodies of the inner plug 2 interposed between the container bodies 1 and 4 which are vertically stacked. An opening 9 for communicating between 1 and 4 is formed near the periphery as an annular shape. Therefore, the second packing 13 for closing the annular opening 9 and sealing between the container bodies 1 and 4 also has the same peripheral arrangement and is screwed in. Since the tightening force at that time acts as strongly as the peripheral portion of the container, the sealing property for separating two liquids can be improved as much as possible.

The liquid mixing is performed by screwing the lower container body 1 downward until the engaging projections 27 and 28 come into contact with each other as shown in FIG. 2 and opening the annular opening 9 of the inner plug 2. The mixed liquid may be poured out by inverting the container, squeezing the body 16 and pouring it out from the small diameter opening at the tip of the nozzle cap 17.

Second embodiment (FIG. 3)

In this embodiment, the length of the intermediate tubular member 3 is made short, and thus the overall length of the container is made short, so that the inner lid 14 of the intermediate tubular member 3 is located above the inner peripheral edge of the inward flange 12. It is formed by standing upright. In this example, the reinforcing material 22 and the ring stopper 23 of the inner lid 14 are omitted. This embodiment can also achieve the same effect as the first embodiment.

In the above embodiment, the upper container body 4 is not limited to the squeeze shape.

[0029]

[Effect of device]

 As described above, according to the present invention, the upper and lower container bodies 1 and 4 for filling different liquids are vertically stacked by the screwing of the peripheral portion via the intermediate tubular member 3, and are attached to the top of the mouth of the lower container body 1. In a two-liquid mixing container that seals between the two container bodies 1 and 4 by the inner stopper 2, an opening 9 for communicating both container bodies 1 and 4 at the time of mixing, which is formed in the inner stopper 2, is annularly arranged near the periphery, The annular opening 9 is closed by press-fitting the intermediate tubular member 3 which is screwed and mounted at the time of assembling with the inner lid 14 integrated with the tubular member 3 via the packing 13 so that the packing 13 is strongly tightened. It is pressed against the opening 9 by force, so that it is possible to always seal the two container bodies 1 and 4 in a substantially completely sealed state.
