[Industrial applications]

 The present invention relates to a container with a dropper used for taking out a lotion or a liquid medicine.

[0002]

[Prior art]

 For example, a device of Japanese Utility Model Laid-Open No. 5-10258 is known. The container consists of a container body that stands up the mouth and neck and a cap that is screwed onto the mouth and neck, and the cap is opened from the middle part of the peripheral wall where the lower half is screwed onto the outer surface of the mouth and neck of the container. The dropper pipe is hung down into the container body through an inward flange that is placed on the upper end surface of the neck and protrudes, and the lower part of the elastic dome portion is fitted to the upper end of the pipe, and both left and right parts of the upper part of the peripheral wall are fitted. A dropper member with a split groove installed vertically, and a pin that protrudes outward from both left and right parts of the lower end of the cylinder that hangs from the peripheral edge of the top plate into the split groove, and pushes down vertically from the center of the top plate. A push button having a rod placed on the elastic dome-shaped portion, an outer cylinder on the outer surface of the peripheral wall of the spout member, and an inner cylinder on the outer surface of the peripheral wall of the peripheral wall are provided in the recesses provided in a predetermined angle range. The engaging element can be rotated in the recess and And a tubular operating member that is fitted so that it cannot move up and down by a ridged line.A cam mechanism is provided on the outer surface of the tubular portion of the push button and the inner surface of the tubular operating member outer tube. The push button is pushed down when the engagement element of the operation member comes into contact with the end of the recess of the dropper member in the circumferential wall tightening direction, and the push rod of the push button pushes down and squeezes the elastic dome portion. The elastic dome-shaped portion elastically restores to push up the push button when the contact portion comes into contact with the end portion of the recess in the loosening direction, and by rotating the tubular operating member in the loosening direction from this state, The peripheral wall of the dropper member is provided so as to be unscrewed from the neck portion of the container body through the engaging element. Air is discharged into the dropper tube by squeezing the elastic dome portion, liquid inside the container is sucked in due to its elastic restoration, and the dropper member is unscrewed, and then the pushbutton is pushed down to pour out the dropper tube liquid. To do.

[0003]

[Problems to be solved by the device]

 The conventional dropper container described above has the convenience that the cap with a dropper can be automatically sucked into the pipette pipe by simply removing the cap from the state where the cap with a dropper is screwed into the neck of the container body and tightened. Since the upper part of the elastic dome at the upper end of the dropper tube is pressed down by the push-down bar of the push button and squeezed when the cap is screwed into the mouth and neck and tightening is completed, the elastic dome-shaped part has large elastic fatigue. was there.

The present invention retains the advantage of the above-mentioned conventional dropper container in which the liquid in the container is automatically sucked into the dropper tube when the cap is removed from the neck and neck of the container body, and the cap is attached to the neck and neck of the container body. At the same time, the elastic dome made it possible to maintain the elastically restored state.

[0005]

[Means for Solving the Problems]

 In order to solve the above problems, the container of the present invention has a container body 2 in which a locking projection 5 is provided around the outer periphery of the mouth / neck portion 4 and upward corrugated teeth 6 are provided around a reduced diameter portion above the projection 5. And a dropper cap 3 which is detachably attached to the container body 2. The drop cap 3 has a downward corrugated tooth 11 meshed with the corrugated tooth 6 around the inner peripheral lower end edge of the peripheral wall 12. At the same time, the dropper tube 14 is hung from the inner peripheral edge of the inward flange 13 extending from the upper edge of the peripheral wall 12 into the container 2, and the inner surface projections of the plurality of elastic engaging pieces 15 are hung from the outside of the lower surface of the peripheral wall 12. A dropper member 7 in which a line 16 is engaged with the locking projection 5, an elastic dome 21 which covers the upper end opening of the spout tube 14 and is fixed to the flange 13 so as to be capable of being contracted and deformed, and the dropper member peripheral wall 12 An outer cylinder 9 which is vertically movable around the outer periphery and has a lower part fitted therein so as not to slip out; The push button 10 is fitted to the upper part of the cylinder 9 so as to be vertically movable and cannot be pulled out, is attached to the dropper member 7 so as to be able to be pushed down in a biased state, and is capable of pushing down the elastic dome 21. A recess 26 is provided around the inner peripheral surface of the lower portion of the outer cylinder 9, and the inner wall of the peripheral wall 24 above the recess 26 and the outer surface of the dropper member peripheral wall 12 are engaged with each other so as to be vertically movable and non-rotatable when the outer cylinder 9 is pushed down. The engaging means 17 is provided and configured.

[0006]

When the outer cylinder 9 is pushed down against the elastic force of the spring 32 from the state shown in FIG. 1, the engaging means 17 between the inner surface of the outer cylinder 9 and the outer surface of the dropper member peripheral wall 12 are non-rotatably fitted to each other. . At this time, since the push button 10 is also pushed down at the same time, the elastic dome 21 is compressed and the air in the spout tube 14 is discharged. Then, when the outer cylinder 9 is rotated while being pushed down, the dropper member 7 is also rotated by the engaging means 17, so that the member 7 is pushed upward by the rotation of the meshing portion of the peripheral wall 12. As a result, the protrusion 16 of each elastic engagement piece 15 gets over the locking protrusion 5 on the outer periphery of the mouth / neck portion 4 and moves upward. At this time, since the recess 26 is provided in the lower portion of the inner circumference of the outer cylinder 9, each projection 16 can be easily climbed over.

Next, when the outer cylinder 9 is pulled up, the outer cylinder 9 first moves upward with respect to the dropper member 7, at which time the elastic dome 21 is restored to its original state and the liquid in the container body 2 is removed. The cap 3 is sucked up into the dropper cylinder 14, and then the entire cap 3 is pulled up to come off from the container body 2. Then, when the push button 10 is pushed down, the liquid in the dropper cylinder 14 is poured out.
