[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a two-part mixing and dropping container in which two types of storage agents such as liquid and powder separately stored therein are mixed at the time of first use, and are used by dropping and using a dropper function. It is.
[0002]
[Prior art]
The prior art of a two-part mixing container, in which two parts are mixed at the time of use, as a conventional technique of a two-part mixing container, has an upper end opened into the mouth and neck of a container body having a shoulder under the mouth and neck and containing any liquid. A dissimilar liquid storage cylinder whose lower bottom is closed by a thin film is fitted, and a cap is fitted to the outer periphery of the mouth and neck so as to be able to descend, and the cap is closed so that the upper wall of the top wall can be cut and opened. The tubular portion is projected upward, and further communicates with the tubular portion from the lower surface of the top wall to the inner peripheral wall of the storage cylinder in a watertight manner and can be pressed down and a tubular body connected to a part of the tubular body.

Japanese Patent Application Laid-Open No. 2000-85828
In addition, in a dropping container using a dropper mechanism, an elastic button portion that expands in a dome shape and elastically deforms is formed integrally with the cylindrical wall portion of the container so as to be thin, thereby reducing the number of parts and reducing the manufacturing cost of the container. Is being reduced.
[0005]
[Problems to be solved by the invention]
However, in the above-mentioned conventional technology, in order to mix the two agents, the cap is pushed down against the container body, and the cylinder is fitted into the heterogeneous liquid storage cylinder closely assembled to the mouth and neck of the container body. When this is done, the pressure in the container body is increased by at least the volume of the cylinder fitted into the different liquid storage cylinder, and the increased internal pressure causes the mixture to be ejected or the sealing performance of the sealing function part to be reduced. However, there is a possibility that the inconvenience of "."
[0006]
In the case where the elastic button part, which is a dropper function part, is formed so as to be thin integrally with the cylindrical wall constituting part of the container, the thickness of the elastic button part is made sufficiently thin and the content liquid is dropped. Although it is easy to perform the dispensing operation, if it is actually used, the speed of return to the original shape of the elastic button part that has collapsed and inverted has been slow, and it takes time for continuous pouring operation. There was a complaint that the deformed elastic button part could not return to its original shape and could not be poured out.
[0007]
Therefore, the present invention has been devised to solve the above-described problems in the prior art. In a two-part mixing dropping container utilizing a dropper function, when mixing two parts, the rise in the internal pressure of the container is prevented. The technical task is to increase the elasticity of the elastic button part, which is a functional part, to prevent illegal ejection of the mixed liquid and deterioration of the sealing function after mixing two agents, and to ensure that the mixed liquid is stable and continuous. The purpose is to obtain a dripping and pouring operation.
[0008]
[Means for Solving the Problems]
In the present invention for solving the above technical problems, the means of the invention described in claim 1 is:
Providing a mouth at the upper end of the body, hanging down a dripping cylinder piece forming a dripping port at the lower end, having a main body for storing the first agent,
From the upper end of the hanging cylinder, which is fitted tightly and immovably into the mouth of the main body and whose lower end is closed with a thin film, a screwing cylinder in which a thread is engraved at the lower part of the outer peripheral surface is erected and connected, and the second agent is provided. Having an inner plug for storing
The outer cylinder has an outer cylinder that is externally fitted and screwed into the screwing cylinder of the inner plug. The upper end of the outer cylinder is closed with a dome-shaped elastic button portion via an inner flange-shaped top wall, and the inner end is closed at the lower end. A cutting blade for cutting the thin film of the plug is provided, and an inner cylinder fitted into an integral body of the hanging cylinder and the screwing cylinder of the inner plug is continuously provided, and assembled to the inner plug so as to be rotatable and vertically movable. Having an outer plug,
Having a stopper ring that can be removed by breaking, which disables the screw-down displacement of the outer plug with respect to the inner plug,
Having a lower cap detachably attached to the lower end of the main body to open and close the drip port formed by the dripping cylinder piece of the main body,
A seal portion that performs a sealing function with a stop ring attached between the inner peripheral surface of the screwing cylinder of the inner plug and the outer peripheral surface of the inner cylinder of the outer plug, Forming a leak portion that exhibits a leak function when the plug body is displaced downward,
A seal function portion that performs a sealing function between the upper end surface of the screwing cylinder of the inner plug and the lower surface of the top wall of the outer plug when the outer plug is positioned at the lowermost position with respect to the inner plug. Providing,
On the inner surface of the elastic button portion of the outer plug, a plurality of ridge-shaped reinforcing ribs having a larger sectional area as being away from the center are integrally provided radially,
By screwing down the outer plug after removing the stopper ring, the outer blade cutting blade cuts the thin film of the inner plug,
It is in.
[0009]
According to the first aspect of the invention, before the two components are mixed, the stopper ring does not allow the outer plug to be displaced by screwing down with respect to the inner plug, so that the first agent and the second agent are separated. The integrated storage is safely maintained, and the hermetically sealed storage of the second agent is ensured by the sealing action of the seal portion (see FIG. 1).
[0010]
At the first use, after the stopper ring is broken and removed, the outer plug is screwed in and lowered with respect to the inner plug, and the cutting blade of the outer plug breaks the thin film of the inner plug. Falls into the main body in which the first agent is stored, and the two agents are mixed (see FIG. 2).
[0011]
When the outer plug body is displaced downward with respect to the inner plug body, as the descending displacement of the outer plug body proceeds, the seal part loses its sealing function and the leak part performs its leak function. The pressure in the container, which is going to rise by the cylinder going down into the combination of the main body and the inner plug body, is leaked to the outside through the leak part, so that the pressure inside the container rises when mixing the two agents. Absent.
[0012]
When the outer plug reaches the lower limit with respect to the inner plug, the sealing function between the inner plug and the outer plug exerts a sealing function. Keep tightly closed without raising.
[0013]
From this state, by removing the lower cap and pressing the elastic button on the upper end with a fingertip, the mixed liquid is poured out from the drip port at the lower end of the main body in a dripping manner. It is possible to accurately recognize the dispensed amount.
[0014]
Due to the action of the plurality of reinforcing ribs provided on the inner surface of the elastic button portion exhibiting the dropper function, the elasticity acting as a restoring force against deformation becomes stronger from the center portion to the peripheral end portion. Therefore, the original shape is quickly restored from the collapsed inverted deformation state, and the restoration is reliably performed.
[0015]
According to a second aspect of the present invention, in the configuration of the first aspect of the present invention, a circumferential ridge-shaped sealing member is provided around the upper end of the inner peripheral surface of the screwing cylinder of the inner plug, and the outer periphery of the inner cylinder of the outer plug is formed. At the upper end of the surface, at the lower half of the upper end, a smooth peripheral surface where the sealing strip is in close contact was formed to form a seal portion, and at the upper half of the same upper end, a vertical groove was formed to form a leak portion. That is,
[0016]
According to the second aspect of the present invention, the sealing is provided by the sealing strip provided on the screwing cylinder of the inner plug, and the smooth peripheral surface and the vertical groove provided vertically adjacent to the inner cylinder of the outer plug. Since the seal part and the leak part are provided, the combination of the seal part and the leak part can be configured extremely easily, and the switching between the seal function and the leak function can be performed according to the downward displacement of the outer plug with respect to the inner plug. It will be performed appropriately and stably.
[0017]
A third aspect of the present invention is the same as the first or second aspect of the invention, except that a packing is arranged on the lower surface of the top wall of the outer plug to form a seal function portion.
[0018]
According to the third aspect of the present invention, since the seal function portion is constituted by the packing having a high sealing property, the seal between the inner plug and the outer plug after the mixing of the two components is stably and firmly provided. Achievement can be maintained.
[0019]
According to a fourth aspect of the present invention, in the configuration of the first or second aspect of the present invention, one of the upper surface of the screwing cylinder of the inner plug and the lower surface of the top wall of the outer plug facing the upper surface of the screwing cylinder is provided. And that a sealing function portion is formed by peripherally providing a sealing strip.
[0020]
According to the fourth aspect of the present invention, since the sealing function portion is constituted by a part of the inner plug or the outer plug without using a dedicated member for sealing, the number of parts is reduced accordingly. In addition, since the outer plug needs to be integrally provided with the elastic button portion, it is formed of a relatively soft material, so that the softness of the outer plug effectively acts on the sealing action. It is possible.
[0021]
The invention described in claim 5 is obtained by adding four reinforcing ribs arranged in a cross shape to the configuration of the invention described in claim 1, 2, 3 or 4.
[0022]
According to the fifth aspect of the present invention, the elasticity can be substantially uniformly increased along the circumferential direction without complicating the structure of the elastic button portion, and the degree of the increased elasticity is also reduced. , It is easy to avoid excess.

【The invention's effect】
The present invention has the above-described configuration, and has the following effects.
According to the first aspect of the present invention, even if the outer cap is rotated and pushed into the inner cap to reduce the internal volume of the container for mixing the two agents, the leak action of the leak portion allows the container to be closed. Since the internal pressure does not increase and is maintained at normal pressure, when the lower cap is removed to drop and pour the mixed solution, the mixed solution may be ejected by the internal pressure, or the sealing property between the constituent members may be reduced. Thus, the container can be made to function safely without causing any inconvenience.
[0037]
In addition, when the outer plug body that has been rotated and lowered with respect to the inner plug body reaches the lower limit in order to mix the two agents, the part that formed the leak passage of the leak part is caused by the sealing action of the sealing function part. Since the container is hermetically sealed, the container can be reliably sealed after the two agents are mixed, and the mixed solution can be stored and held safely.
[0038]
In addition, the elastic button part that exerts the dropper function has a strong elasticity that acts as a restoring force against deformation due to the shape of the reinforcing rib, so that the original state from the deformed state can be reliably and quickly achieved As a result, a smooth and quick dropping and pouring operation can be reliably obtained.
[0039]
According to the second aspect of the present invention, the combination of the seal portion and the leak portion can be obtained with a very simple configuration, and since the seal portion and the leak portion are vertically adjacent to each other, the sealing function and the leak portion can be obtained. Switching to the function is performed appropriately, promptly and stably, so that the mixing of the two agents can be easily and safely achieved.
[0040]
According to the third aspect of the present invention, since the sealing function portion is constituted by the packing having high sealing properties, a strong and reliable sealing action can be obtained.
[0041]
According to the fourth aspect of the present invention, since the softness of the outer plug body is used as it is for the sealing action, no special member for forming the sealing function portion is required. The part can be configured very simply.
[0042]
According to the fifth aspect of the present invention, the elasticity of the elastic button portion can be increased substantially uniformly and appropriately without complicating the structure of the elastic button portion. Can be demonstrated.
