DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cap with a dropper capable of taking out a liquid content such as a lotion or a chemical solution contained in a container body by a dropper function.

[0002]

2. Description of the Related Art As a typical example of the prior art of a cap with a dropper, a structure disclosed in Japanese Utility Model Laid-Open No. 5-10258, that is, a part with a threaded assembly for a container is constructed, and a dropper tube and an elastic suction body are connected. An inner lid with a combination of a dropper function unit attached to it and an inner lid that cannot be pulled out and is rotatable by a certain angle, and the button for operating the elastic suction body is raised and lowered by turning the inner lid. And an outer lid to be used.

In this prior art, when the container is closed, the button is in a state where the elastic suction body is crushed, and when the outer lid is turned in the opening direction from the closed state, the button is raised. Return the elastic suction body to its original shape, suck the content liquid into the dropper tube,
Next, the inner lid is screwed and turned, and the cap is detached from the container. By operating the button with the cap, the sucked content liquid is poured out to the target location.

[0004]

However, in the above-mentioned prior art, when the container is closed, the elastic suction body is held in the collapsed posture, so that the elastic suction body suffers from elastic fatigue or deformation fatigue. As a result, there is a problem that the dropper function is deteriorated early.

In addition, the inner lid and the outer lid constituting the cap must be assembled so as to be capable of rotating and displacing each other, and this mutual rotating assembling causes the inner lid and the outer lid to relatively rotate. It is necessary to satisfy the relationship that the rotating operation force required to unscrew the inner lid from the container is definitely larger than the operating force required for the inner lid and the inner lid and the outer lid. There is a problem that setting of the structure and the assembling strength is troublesome.

Accordingly, the present invention has been made to solve the above-mentioned problems in the prior art. In addition to the elastic deformation of the elastic dome, the cap is used to unscrew the cap from the container body, and the dropper tube is used. The technical issue is to achieve a constant suction of the liquid content into the container, thereby eliminating the occurrence of deformation fatigue of the elastic dome, which is the source of the liquid suction force, and exhibiting a good dropper function stably over a long period of time In addition, the entire structure and handling can be easily performed by using a structure that achieves a constant suction of the content liquid into the dropper tube by utilizing the relative vertical displacement caused by the turning operation of screwing on and off the cap. The purpose is to be able to simplify.

[0007]

Means for Solving the Problems Among the present invention for solving the above technical problems, the means of the present invention according to claim 1 has a dropper tube, and the pipe main body of the dropper tube is inserted into the container body in a closed posture. It is a cap with a dropper that can be hung down.The operation button is provided at the upper end so that it can not be pulled out and is freely displaceable in a protruding shape. Having a cap body with an inner cylinder connected to the inner cylinder via an inner flange-shaped partition, a top cylinder with a top plate connected to the cylinder tube, covering the top plate, and squeezing with an operation button to operate the hemispherical shell -Shaped elastic dome is densely mounted and assembled, a vent hole is opened in the top plate, and a ventilation tube piece is vertically installed from the center of the top plate,
The upper half of the outer cylinder of the cap body has a cylinder body that is immovably assembled inside, and this cylinder body is mounted inside the cylinder cylinder inner peripheral surface and the ventilation cylinder piece outer peripheral surface so as to be vertically movable while sliding tightly, It has a piston body urged downward by a spring mounted between the cylinder body and a flange piece of a size facing the upper end surface of the mouth of the container body at the upper end of the pipe body of the straight narrow tube. The assembling tubular portion projecting upward from the flange piece cannot be pulled out of the inner cylinder of the cap main body, but is fitted and assembled so as to be vertically movable, and protrudes upward from the inner cylinder of the cap main body. Another object of the present invention is to have a dropper tube in which the upper end of the assembled cylindrical portion is tightly assembled and fixed to the piston body.

In the closed position, the cap with a dropper in which the pipe main body of the dropper pipe is positioned in a hanging manner in the container body,
By the screwing force of the cap body to the mouth of the container body, against the elasticity of the spring, the second combination that is the combination of the piston body and the dropper tube, the cap body, the operation button, and the cylinder body The piston body is located at a first entry position where the piston body enters the cylinder body most deeply with respect to the first combination article which is the combination article with the elastic dome.

When the cap body is rotated in the unscrewing direction from the closed position, the first combination is displaced upward with respect to the container body by this rotation, but the second combination is operated by a spring. As a result, the first combined product and the second combined product are not displaced upward with respect to the container body, and the relative displacement between the first combined product and the second combined product is generated.

[0010] Due to the relative vertical displacement between the first combination and the second combination, the piston body is displaced from the first entry position with respect to the cylinder body to the second entry position, which is shallow enough to enter the cylinder body. As a result, a negative pressure is generated in the cylinder.

The negative pressure in the cylinder acts on the cylinder body of the dropper through the ventilation hole of the cylinder body, the elastic dome, the ventilation cylinder piece of the cylinder body, and the ventilation opening of the piston body. The content liquid is sucked into the tube body.

[0012] The relative displacement between the first combination and the second combination is stopped by the impossible butting of the dropper tube against the inner cylinder of the cap body. , The ascending cap is displaced from the container body together with the container body.

[0013] As described above, since a predetermined amount of the liquid content is suction-stored in the dropper tube of the cap with a dropper when detached from the container body, the user can operate the removed cap with the dropper. The liquid content is poured out by pressing down the button to crush the elastic dome to achieve the liquid content.

When the cap with a dropper is screwed into the mouth of the container body, the resilient force of the spring is reversed against the first combination as the screwing of the cap body to the container body progresses. The combination of the two rises relatively, the piston body enters the cylinder body to the first entry position,
It returns to the initial closed position.

When the cap with a dropper returns to the closed position, even if the liquid remains in the dropper pipe due to the piston body penetrating the cylinder body to the first penetrating position, the contents in the dropper pipe remain. The liquid will be forcibly discharged, whereby the cap with a dropper will always be in a constant state, that is, in a state where no content liquid is located in the dropper tube.

According to a second aspect of the present invention, in the first aspect of the present invention, a guide longitudinal groove is provided on the inner peripheral surface of the inner cylinder of the cap body, and the diameter of the upper end of the inner cylinder is reduced upward. At the lower part of the outer peripheral surface of the cylindrical part with the assembly of the dropper tube, a guide vertical strip that locks from the circumferential direction to the guide vertical groove of the cap body protrudes, and there is a set that protrudes upward from the inner cylinder of the cap body. A stopper ridge is provided on the outer peripheral surface of the upper end portion of the cylindrical portion so that the upper end of the reduced-diameter distal end portion of the cap body abuts from below so that it cannot climb over the cap body.

According to the second aspect of the present invention, the first contact of the reduced diameter tip portion against the stopper ridge from below and the contact of the flange of the dropper tube from above the partition wall of the cap body with the stopper are provided. In addition to achieving the assembling of the second combination with respect to the combination, which can be displaced up and down at a constant stroke in which the first combination can be disengaged, the first combination and the second combination can be engaged with the guide flutes. Since the relative rotation with respect to the combination is disabled, it is possible to stably achieve and maintain the tight sliding contact of the piston body with the cylinder body.

According to a third aspect of the present invention, in the first aspect of the invention, the cap body is externally assembled to a main body cylinder having an outer cylinder and an inner cylinder, and the outer cylinder is mounted on the outer cylinder of the main body cylinder. At the top of the outer cylinder of the cover cylinder and the body cylinder where the operation buttons are assembled internally,
In addition to the above, the outer cylinder is provided with a fitting assembly in a form of being extended upward, and a spacer ring which is located inside the upper end of the cover cylinder and sets a lower limit of the operation button.

According to the third aspect of the present invention, since the cover tube can have a simple tube structure, the cover tube can be made of a metal material having excellent decorativeness.
When the cover cylinder is made of metal, the leakage of the adhesive that achieves the adhesive fixation of the synthetic resin main body cylinder to the metal cover cylinder from the upper edge of the main body cylinder to the operation button operation area is achieved by the spacer ring. In addition, since the lower limit position setting function portion of the operation button is formed on the spacer ring separate from the main body cylinder, there is no problem in assembling the cylinder body and the elastic dome to the main body cylinder. The lower limit position of the operation button can be set.

According to a fourth aspect of the present invention, in the first aspect of the present invention, an opening hole is formed in the partition wall portion of the cap body inside the cylinder cylinder of the cylinder body so as to vertically penetrate the partition wall. In addition.

According to the fourth aspect of the present invention, the relative displacement between the first combination and the second combination is increased and decreased.
By allowing the inflow and outflow movement of air in the space below the piston body in the cylinder through the open hole, the relative displacement between the first combination and the second combination can be smoothly achieved. So that

[0038]

Since the present invention has the above-described structure, the following effects can be obtained. The elastic dome made of a soft elastic material, which is one of the constituent parts of the dropper function part, is crushed and deformed only at the time of discharging and sucking the content liquid, and naturally in other states such as when the container body is sealed. Since it has a stable shape, there is no risk of permanent deformation or elasticity deterioration due to deformation fatigue or the like, and a good and stable dropper function can be reliably obtained for a long period of time.

[0039] Only by the unscrewing operation of the cap with the dropper with respect to the container body, it is inevitable that the constant amount suction of the content liquid into the dropper tube and the detachment of the cap with the dropper from the container body are achieved. There is no need to set an exact magnitude relation to the magnitude of the sliding resistance of each of the movable parts, thereby simplifying the combined structure of the movable parts and facilitating handling.

According to the second aspect of the present invention, it is not necessary to simply attach the combination of the dropper tube and the piston to the combination of the cap body and the cylinder so as to be non-separable and vertically movable. In addition, by assembling the piston bodies so as not to be displaceable relative to each other, the tight assembly of the piston body with respect to the cylinder body is stably maintained, and thereby a good dropper function is stably maintained.

According to the third aspect of the present invention, since the separate spacer ring is attached to the cap main body, the adhesive for bonding and fixing the main body cylinder and the cover cylinder leaks into the main body cylinder. Surely block out with a spacer ring,
It is possible to obtain a favorable operation of raising and lowering the operation button, and to set the lower limit of the operation button without difficulty without assembling the cylinder body to the main body cylinder.

According to the fourth aspect of the present invention, since the vertical displacement of the piston body with respect to the cylinder body can be smoothly and smoothly achieved, the contents accompanying the screwing operation of the cap with the dropper from the container body can be achieved. A constant amount of liquid can be reliably and accurately sucked into the dropper tube.
