Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a method for automatically mixing a solvent and a mixing substance existing in a container cap by mounting the container cap on a container body containing a predetermined amount of a solvent. The present invention relates to a container for mixing.

[0002]

2. Description of the Related Art Conventionally, for example, when a solute is dissolved in a desired solvent to obtain a solution, first, a solvent taken out from a solvent container and weighed is put into a previously prepared mixing container. The solute taken out from the solute container and measured is
It was put in the mixing vessel and mixed with the solvent.

[0003] In particular, when a concentrated liquid for dilution or a powder that dissolves (hereinafter, collectively referred to as a mixing substance) is used, a predetermined amount of the mixing substance packaged as a single use is used. Adjust by mixing with solvent (mainly water)
Alternatively, when the mixing substance was not packaged as a single-use amount, the mixing substance was measured once using a measuring jig and mixed with a certain amount of solvent.

[0004]

However, in the conventional method, it takes time and effort to take out the substance for mixing from a package such as paper or a container, or to measure the substance for mixing, and the amount of solvent is fixed. We had to weigh. In this case, when weighing or transferring the mixing substance or the solvent, troubles such as the spilling of the mixing substance or the solvent and adhesion to the hand are likely to occur. In addition, there is a high possibility that a measurement error in measurement or a measurement error due to misunderstanding occurs.

[0005] The present invention has been made in view of such circumstances, without automatically unpacking the substance for mixing, to automatically add a corresponding amount of the substance for mixing to a certain amount of solvent in the container body. It is an object of the present invention to provide a container which can be mixed in an appropriate manner.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is directed to a container body containing a solvent and having a threaded opening; A bottomed tubular cap body having a top wall portion, and a bottomed tubular inner plug provided inside the cap body and containing a mixing substance for mixing with the solvent, The inner plug has a bottom portion, a cylindrical side wall portion connected via a weakened portion formed on the periphery of the bottom portion, a screw shaft projecting upward from the center of the bottom portion and integrally formed with the bottom portion,
A detent mechanism for locking relative rotation with the container main body, wherein the cap main body is formed in a cylindrical shape protruding downward from the vicinity of the center of the top wall portion in a downward direction; An internal thread portion formed inside the cylinder of the inner cylinder portion for screwing the screw shaft, wherein the inner plug and the cap body abut the upper end of the side wall portion inside the cap body, The screw shaft and the internal thread portion are connected by screwing in a state where an unthreaded portion is formed, and the cap body is fixed to the container while the rotation of the inner plug is restricted by the rotation preventing mechanism. By screwing to the main body, the screw shaft is moved relatively upward with respect to the cap main body so as to narrow the unthreaded portion, and the bottom is pulled up, and by the upward movement of the bottom, The weakened part formed on the periphery of the bottom is broken Wherein the passage of the mixing material is formed by Rukoto.

According to the present invention, the mixing substance is stored in the inner stopper in advance, and is prevented from spilling by being connected to the cap body. In addition, the mixing substance is stored in the inner stopper after being measured in advance, so that measurement errors and troublesome operations at the time of measurement can be reduced.

In order to mix the substance for mixing with the container body containing the solvent, the upper end of the side wall portion is brought into contact with the inside of the cap body so that the upper portion of the side wall portion relative to the cap body is moved upward. Cap body so that the cap body is screwed to the container body and the screw shaft is narrowed in the unthreaded portion while locking the movement and restricting the rotation of the inner plug by the rotation preventing mechanism. Is moved relatively upward. By moving the screw shaft upward, the bottom integrally formed with the screw shaft is also moved upward, the weakened portion formed on the periphery of the bottom is broken, and the passage of the mixing substance is formed. This causes the mixing substance to fall into the container body. Therefore, the mixing substance is stably and reliably supplied into the solvent without spilling or sticking to the hand.

Further, since the screw shaft and the bottom are integrally formed, even if the weakened portion formed on the periphery of the bottom is broken, the broken bottom does not fall into the solvent.

Since the bottom locking means for supporting the bottom whose peripheral edge is broken is provided inside the cap body, the passage of the mixing substance is stably secured.

The bottom portion is tapered so as to be bifurcated from the lower end of the screw shaft, one end is connected to the inclined bottom portion via a hinge portion, and the other end is connected to the weakened portion. A flat bottom portion, and after the weakened portion is broken, the flat bottom portion is rotated downward while being supported by the hinge portion. Therefore, after the weakened portion is broken, the passage is formed stably and reliably.

Further, the bottom locking means is formed in a tapered shape at the tip of the inner cylindrical portion so as to follow the inclined bottom, and the flat bottom rotated downward is stable at the tip. And the passage is stably secured.

A flange portion having a larger diameter than the side wall portion is formed at an upper end of the side wall portion, and a step portion for engaging the flange portion is provided at an upper end of the cylindrical hollow portion. After the cap body and the inner plug are connected, the inner plug is locked from moving up and down relative to the cap body, and the inner plug and the cap body are stably connected.

Since an annular projection is formed on the upper end surface of the flange portion, the contact area between the upper end surface of the flange portion and the inside of the top wall portion of the cap body is small. For this reason, even if the cap body is rotated while restricting the rotation of the inner plug, the contact area is small, so that the friction is small and the cap body is smoothly rotated.

[0015] The contour of the weakened portion may be a petal shape composed of a plurality of arcuate lines. By forming the petal shape having a long contour line, the opening area can be increased when the bottom is broken, so that the passage of the mixing substance is formed widely.

Even if it moves upward, the cap body 1 of the side wall 21
The position relative to does not change.

As the cap body 1 is screwed down and moves downward, the inner plug 20 is made up of the inner plug projection 24 and the container projection 43.
Is moved downward while sliding, and at the same time, the female screw portion 5 and the screw shaft 25 are screwed.

At this time, since the inner plug convex portion 24 and the container convex portion 43 are formed so as to extend in the cylindrical axis direction, they can slide stably with each other. The contact area with the container convex part 43 is formed large.

An inner projection 23c and an outer projection 23d are formed in an annular shape on the upper end surface 30 of the flange portion 23, and the contact area of the large-diameter portion 9 with the contacting inner wall surface 9a is reduced. I have.

When the screw shaft 25 is screwed, the unthreaded portion 5a is narrowed, and the bottom portion of the inner plug 20 is moved so as to be pulled up relatively with respect to the cap body 1 by the narrowed portion. 6 and the bottom 22 are approached.

As shown in FIG. 10, when the screw shaft 25 is moved upward with respect to the cap body 1, the bottom 22 integrally formed with the screw shaft 25 is pulled up together. Be moved. And the bottom 22
Is weakly bent, and then the weakened portions 28 formed in two arcs around the bottom 22 are broken by being pulled. By breaking the weakened portion 28, the flat bottom portion 22b of the bottom portion 22 hangs downward while being supported by the hinge portion 26. Then, the screw shaft 25 is deformed so as to be linearly connected to the inclined bottom portion 22 a formed in a bifurcated tapered shape at the lower end of the screw shaft 25, and a passage R of the mixing substance F is formed near the weakened portion 28.

As shown in FIG. 11, the cap body 1 is screwed almost completely. At this time, the bottom portion 22 is
The flat bottom portion 22b deformed so as to be linearly connected to the inclined bottom portion 22a can be maintained in the shape because the flat bottom portion 22b is supported along the distal end portion 6 which is a bottom locking means formed in a tapered shape.

Thus, the mixing substance F stored in the cylindrical hollow portion 7 of the inner plug 2 flows out of the passage R and is supplied into the container body 40. At this time, the broken bottom 22
Is maintained in a tapered shape.
Flows out of the passage R and also flows out along the tapered slope of the bottom 22.

Then, the mixing substance F is supplied to the solvent L,

Because there is no, it does not become difficult to drink.

Since the inner plug protruding portion 24 and the container protruding portion 43 are formed so as to extend in the axial direction of the cylinder, respectively, when they are engaged and brought into contact with each other, a large contact area can be obtained between them. The rotation of the inner plug 20 can be regulated stably. Further, since the inner plug convex portion 24 and the container convex portion 43 are formed long in the cylinder axis direction, the inner plug 20 slides the inner plug convex portion 24 stably downward while being in contact with the container convex portion 43. Be moved.

Since the screw shaft 25 and the bottom 22 are integrally formed, the bottom 22 does not fall into the solvent even if the weakened portion 28 formed on the periphery of the bottom 22 is broken.

The bottom portion 22 is tapered so as to be bifurcated from the lower end of the screw shaft 25 and a flat bottom portion 22 formed between the inclined bottom portion 22a and the weakened portion 28.
b, and a hinge portion 26 for connecting the inclined bottom portion 22a and the flat bottom portion 22b. After the weakened portion 28 is broken, the flat bottom portion 22b is rotated downward while being supported by the hinge portion 26. Therefore, after the weakened portion 28 is broken, the passage R
Are formed stably and reliably.

The distal end portion 6 of the inner cylindrical portion 4 is formed in a tapered shape along the inclined bottom portion 22a, and the flat bottom portion 22b turned downward is supported by the distal end portion 6, so that the passage R
Is secured stably.

The shape of the bottom 22 after the fracture is tapered so as to be maintained. Therefore, since the mixing substance F flows out along the slope of the bottom portion 22,
The mixing substance F flows out stably without remaining inside the storage hollow portion 27.

At the upper end of the side wall portion 21, a flange portion 23 having a larger diameter than the side wall portion 21 is formed, and the cylindrical hollow portion 7 is formed.
The upper end of the inner step 1 for engaging the flange 23
0a and the outer step 10b are provided, so that after the cap body 1 and the inner plug 20 are connected, the movement of the inner plug 20 in the vertical direction relative to the cap body 1 is stopped. And the cap body 1 are stably connected.

Since the annular inner protruding portion 23c and the outer protruding portion 23d are formed on the upper end surface 30 of the flange portion 23, the upper end surface 30 of the flange portion 23 and the contact inner wall surface 9a of the large diameter portion 9 are formed. The contact area is small. For this reason, even if the cap body 1 is rotated while restricting the rotation of the inner plug 20, the contact area is small and the friction is small, so that the cap body 1 is smoothly rotated.
