Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a two-liquid mixing container.

[0002]

[Prior Art] [Problems to be solved by the device]

 As a two-liquid mixing container, the lower part of the intermediate tubular member was screwed into the mouth of the first container, and the lower end was attached to the upper part of the intermediate tubular member and the lower end was attached to the seat of this tubular member. The second container with the mouth closed is screwed on, and the second container is screwed back from the intermediate tubular member to detach the cap from the lower mouth downward and uncap the second container. The present applicant has already proposed a container configured to drop and transfer the liquid in the first container to mix the two liquids (Act No. Sho 63-6032). This container can be mixed simply by unscrewing the second container, without preparing a special mixing container, and without the need for a troublesome pouring operation, and the number of constituent parts is small. Since the final product can be assembled by simply screwing and fitting with each other, it has various effects such as a simple structure and convenience without requiring tools and labor for assembling.

However, when filling the liquid in this container, first, the first liquid is filled in the first container, and then the intermediate tubular member is screwed into the mouth / neck portion of the first container, and then the plug member is attached to the lower mouth portion. The second container, which has been fitted and closed, is mounted on the intermediate tubular member by fully screwing the thread of the second container into the thread groove. That is, the locking ridges projecting from the outer peripheral lower end of the peripheral wall of the plug body by this mounting are forcibly pushed into the inner peripheral wall of the seat and pierce through the inner peripheral wall of the seat, and are locked onto the lower peripheral surface of the inner peripheral wall so as not to move upward. The outer peripheral surface of the lower half portion of the peripheral wall is in a free state with a slight gap from the inner peripheral surface of the inner peripheral wall of the seat. In this state, the second container is filled with the liquid, and then a cap is attached to the upper opening of the container to seal the opening.

Therefore, when the locking projection of the stopper does not exactly engage with the inner surface of the lower end of the inner peripheral wall of the seat, when the container is accidentally tilted or the container is tilted after mixing two liquids, The liquid in the first container may leak from this portion to the outside through the gap between the second container body and the intermediate tubular member. Further, in order to eliminate such inconvenience, the dimensional accuracy of each material in this portion must be made extremely high, which complicates the manufacturing and necessitates equipments accordingly.

[0007] Also, it seems that such an inconvenience can be eliminated by fitting the outer periphery of the lower end of the second container peripheral wall and the inner surface of the intermediate tubular portion above the seat so as to be liquid-tight and rotatable, but With a structure like the first container with a mouth, it cannot be done unless a split mold is used for molding, so a slight ridge is generated on the outer peripheral surface due to the gap between the split molds, and a good seal is obtained. I can not get sex.

The present invention proposes an excellent two-liquid mixing container that overcomes the above-mentioned drawbacks of the prior art.

[0007]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the container of the present invention is capable of pivoting and descending to the first container body 2 in which upper and lower mouth / neck portions 2b and 2c are protruded above and below the body portion 2a and the outer periphery of the lower mouth / neck portion 2c described above. A first bottom cap 3 in which a peripheral wall 3a is screwed to close the opening of the first container lower mouth / neck 2c in a liquid-tight manner, and a peripheral wall 5a non-rotatably fitted to the outer periphery of the upper mouth / neck 2b. The top wall 5b is extended from the upper edge, and the top wall 5b is penetrated and the top end is formed in the nozzle 5d. The upper mouth / neck portion 4b fixed to the inner circumference from the lower side by rotation is made to stand upright from the upper surface of the body portion 4a, and the lower mouth / neck portion 4c is hung from the lower surface of the body portion 4a. The second container body 4 having a size that can be inserted from the neck portion 2b, and the peripheral wall 6a screwed to the outer circumference of the lower mouth neck portion 4c of the second container body 4 from the lower end edge to the bottom wall 6b. And a second bottom cap 6 formed by extending and liquid-tightly closing the opening of the lower neck 4c of the second container body, and a locking cylinder standing upright from the upper surface of the bottom wall 3b of the first bottom cap 3. The lower end of the second bottom cap 6 screwed to the lower neck 4c of the second container body in the portion 3c is press-fitted so that it cannot be pulled out from above and is rotatably attached to the lower portion of the inner circumference of the locking cylinder portion 3c. A vertical protrusion 3e running vertically is provided, and an engaging protrusion 6f that engages with the vertical protrusion 3e only by rotating in a predetermined direction is attached to a support shaft 6e vertically extending from the rear surface of the second bottom cap bottom wall 6b. When the first bottom cap 3 is projected and is screwed down, the vertical protrusions 3e and the engaging projections 6f are engaged with each other, and the second bottom cap 6 is screwed down. And the inside of the second container 4 communicate with each other.

[0008]

[Action]

 When the first bottom cap 3 is screwed down from the state of FIG. 1, that is, when the first bottom cap 3 is rotated in the direction of arrow B in FIG. The engaging protrusion 6f is engaged to rotate the second bottom cap 6. Along with that, the second bottom cap is screwed down and, as shown in FIG. 2, it is disengaged from the lower neck 4c of the second container body and the liquid in the second container body 4 flows into the first container body 2, The liquids are mixed.

Next, if necessary, the container is shaken sufficiently to agitate the mixed liquid, and then the nozzle cap 11 is removed to squeeze the first container body 2a so that the mixed liquid passes through the cut hole 5g and the tip of the nozzle 5d. More pouring out.
