 In the lid with a dropper according to claim 1, the locking projection is engaged with the rib of the outer lid when the outer lid is idling with respect to the inner lid during the lid closing operation (turning the outer lid toward the lid closing direction). The mating button is integrated with the outer lid and spins against the inner lid. At this time, the locking projection of the button is guided in the spiral direction by the spiral guide groove on the peripheral wall of the inner lid and moves toward the lower end of the guide groove. Further, since the locking projection of the button is engaged with the vertical groove of the rib of the outer lid and can only be moved up and down, the button is moved downward, and the elastic suction body is pressed by the button to be recessed. On the other hand, when opening the lid from this state, when the outer lid is idling with respect to the inner lid, the button with which the locking projection engages the rib of the outer lid is integrated with the outer lid Spin idle. At this time, the locking protrusion of the button is guided by the guide groove of the peripheral wall of the inner lid and moves toward the upper end of the guide groove. Further, since the locking protrusion of the button is movable up and down with respect to the rib of the outer lid, the button is moved upward, the pressing force of the elastic suction body is released, and the elastic suction body expands due to its elastic return force. With the return of the elastic suction body, the liquid content in the container is sucked into the elastic suction body through the dropper tube.

In the lid with a dropper according to claim 2, since the outer shape of the outer lid and the button is non-circular in plan view, the outer lid is idling with respect to the inner lid during the closing operation or the opening operation. At this time, the button rotates integrally with the outer lid against the inner lid.

In FIG. 1, reference numeral 10 indicates an inner lid provided with a dropper tube 11, reference numeral 20 indicates an outer lid, and reference numeral 30 indicates a button. The reference numerals 10, 20, and 30 indicate the lid with a dropper of the present invention. Is basically composed.

As shown in FIGS. 1 and 2, the inner lid 10 is a tubular member whose lower portion 10a is detachably fitted to the outer periphery of the mouth portion 51 of the bottle container 50, and the inner lid 10 has a mouth portion. A protrusion 10b that engages with a horizontal screw 51a on the outer periphery of the portion 51 is provided. Further, a dropper tube 11 having a length reaching the inner bottom portion of the bottle container 50 is integrally attached to the central opening 12a of the middle plate 12 that abuts on the upper end of the mouth portion 51 of the inner lid 10. Further, a bellows-like elastic suction body (bellow) 13 having an elastic deformation force is liquid-tightly mounted on the upper surface of the middle plate 12 so as to surround the spitting tube 11. The inside of the elastic suction body 13 communicates with the inside of the dropper pipe 11, and the liquid substance in the bottle container 50 is sucked through the dropper pipe 11 inside the elastic suction body 13. Further, concave portions 14, 14 for idling the outer lid 20 with respect to the inner lid 10 by a predetermined angle are provided at opposite positions on the outer periphery of the inner lid 10 by a predetermined angle in the circumferential direction. Guide grooves 15, 15 for guiding the button 30 in the vertical direction are formed at positions where the recesses 14, 14 face each other. The guide grooves 15 and 15 include a vertical portion 15a that vertically descends once from the upper end of the peripheral wall of the inner lid 10, an inclined portion 15b that extends obliquely downward from the lower end of the vertical portion 15a, and an inclined portion 15b. And a horizontal portion 15c extending horizontally from the lower end in the circumferential direction.

The outer lid 20 is a tubular member that is assembled to the inner lid 10 from the outside. As shown in FIGS. 1 and 2, the outer lid 20 is attached to the peripheral projection 16 on the outer periphery of the lower end of the inner lid 10. The inner surface of the lower end is undercut-joined. The top plate of the outer lid 20 is formed with an opening 20a through which the button 30 incorporated in the inner lid 10 is projected and retracted. As shown in FIG. 3, the outer lid 20 is disposed in the concave portions 14 and 14 of the inner lid 10 at opposite positions on the inner peripheral surface thereof. Guide ribs 21, 21 that allow the outer lid 20 to idle at a predetermined angle R with respect to the lid 10 are provided in a protruding manner. The guide ribs 21, 21 are formed with vertical grooves 21a for vertically guiding the protrusions 31, 31 of the button 30 incorporated in the inner lid 10. Further, on the back surface of the top plate of the outer lid 20, a cylindrical portion 22 is vertically provided to which the locking portion 13a on the upper surface of the elastic suction body 13 is fitted.

The button 30 is a member for performing a suction operation of the liquid material in the bottle container 50 and a discharge operation of the sucked liquid material. As shown in FIGS. 1 and 3, the base end portion is inside the upper portion of the inner lid 10. And a guide rib 21 on the inner surface of the outer lid 20 through the guide grooves 15, 15 of the inner lid 10 at opposite positions on the outer surface of the base end portion. , 21 are provided with protrusions 31, 31 that engage with the respective vertical grooves 21a. In addition, on the back surface of the top plate of the button 30, a cylindrical portion 33 is vertically provided which allows the elastic suction body 13 therein to be recessed to the maximum extent when the button 30 is sunk from the outer surface of the outer lid 20 into the opening 20a.

Next, the operation of the lid with a dropper configured as described above will be described.

First, the button 30 and the outer lid 20 are assembled into the inner lid 10 in this order to assemble the lid with a spit.

When the lid with a dropper is put on the mouth 51 of the bottle container 50 from above and rotated in the closing direction, a frictional resistance is generated between the projection 10b on the inner surface of the inner lid 10 and the horizontal screw 51a of the mouth 51. While the vertical ribs 21 of the outer lid 20 are located in the recesses 14 of the inner lid 10, the outer lid 20 idles with respect to the inner lid 10. In the meantime, the protrusion 31 of the button 30 is rotated while being attached to the vertical groove 21a of the guide rib 21 on the inner surface of the outer lid 20, while being attached to the outer lid 20, and to the inner lid 10 as shown in FIG. As shown in, the upper end of the guide groove 15 is guided to the lower end through the inclined portion 15b, and as a result, the button 30 descends from the raised position to the most lowered position. When the button 30 is lowered, the bellows-like elastic suction body 13 is depressed as much as possible. At this time, the vertical ribs 21 of the outer lid 20 are engaged with the side surfaces of the concave portion 14 of the inner lid 10, and the outer lid 20 and the inner lid 10 are integrated with each other while the button 30 is submerged in the opening 20a of the outer lid 20. Close.

When the lid is rotated in the opening direction at the time of use, the vertical rib 21 of the outer lid 20 is caused by the frictional resistance generated between the protrusion 10b on the inner surface of the inner lid 10 and the horizontal screw 51a of the mouth portion 51. While located in the recess 14 of the inner lid 10, the outer lid 20 idles with respect to the inner lid 10. In the meantime, the protrusion 31 of the button 30 rotates while being attached to the vertical groove 21a of the guide rib 21 on the inner surface of the outer lid 20 while being attached to the outer lid 20, and to the inner lid 10 of FIG. As shown in, the lower end of the guide groove 15 is guided to the upper end through the inclined portion 15b, and as a result, the button 30 moves up from the lowest position to the highest position. Accompanying this, the elastic suction body 13 that has been recessed to the maximum returns to a dome shape due to the elastic return force of itself and the action of the locking portion 13a, and a negative pressure is applied from inside the elastic suction body 13 to the inside of the dropper pipe 11. It is generated and the liquid substance inside the bottle container 50 is sucked into the elastic suction body 13 through the dropper pipe 11.

When the vertical ribs 21 of the outer lid 20 reach the other side surface of the concave portion 14 of the inner lid 10, the outer lid 20 and the inner lid 10 rotate from there, and the lid is opened.

When the lid is opened and removed from the mouth portion 51 of the bottle container 50, the liquid substance is taken out in the elastic suction body 13 as it is sucked. After that, if the button 30 of the lid is pushed down with the thumb or the like and the elastic suction body 13 is pressed, the liquid substance inside the elastic suction body 13 can be extracted and can be transferred to a small container or taken out as it is. ..

According to the lid with the dropper of the present embodiment, the following effects are obtained.

Following the closing operation of the lid, the elastic suction body 13 is maximally recessed by the interaction of the projection 31, the guide groove 15, and the guide rib 21, and the reverse operation of the above is performed following the opening operation of the lid. By the action, it is possible to surely and easily perform the suction operation of the liquid material. After that, if the lid is opened as it is and taken out from the mouth portion 51 of the bottle container 50, it is possible to smoothly shift to the subsequent liquid material extraction operation. Therefore, the lid with the dropper of the present embodiment smoothly performs the continuous operation from the opening operation of the lid to the pouring of the liquid substance, and has an effect that it is easy to use.

When the lid is closed, the button 30 is completely submerged in the opening 20 a of the outer lid 20, and the top surface of the button 30 is at the same level as the top surface of the outer lid 20. And the aesthetic appearance of the bottle container 50 can be obtained. Further, when the outer lid 20 idles with respect to the inner lid 10, the liquid suctioning operation is performed by the relative mechanism of the protrusion 31, the guide groove 15 and the guide rib 21 in conjunction with the lid closing operation and the opening operation. Since it is performed, it is possible to surely and easily perform the suction operation of the liquid substance with a simple mechanism.

In this embodiment, a lid with a dropper having a circular outer shape in plan view is mainly illustrated, but the lid is not limited to this, and a non-circular shape in plan view as shown in a third embodiment to be described later. It is optional to apply it to a lid with a dropper having a (square) outer shape.

FIG. 5 shows a second embodiment of the present invention, which basically has the same configuration as the above-mentioned embodiment. The lid with dropper of the present embodiment is different from the above-mentioned embodiment in that a part of the shape of the guide groove 15 for guiding the protrusion 31 when the button 30 is moved up and down is changed. That is, as shown in FIG. 5, by extending the vertical portion 15a of the guide groove 15 vertically downward to the height position of the horizontal portion 15c to form a vertical portion 15d, during opening / closing operation of the lid (during liquid material suction operation). While the operation of the projection 31 of the button 30 in FIG. 4) is performed along the inclined portion 15b, the operation of the projection 31 of the button 30 during the liquid material pouring operation after the lid is removed is vertical along the vertical portion 15d. I am trying to make it happen in the direction. As a result, while the liquid material suction mechanism is secured as it is, the liquid lid can be pushed down without rotating the inner lid 20 during the liquid material pouring operation, so that the operation feeling of the button 30 at the time of pouring the liquid material can be improved. Can be improved.

6 to 8 show a third embodiment of the present invention. In the lid with a dropper of this embodiment, the outer lid 20 and the button 30 have a non-circular shape (for example, a square shape) in plan view. Thus, the outer lid 20 and the button 30 rotate integrally without engaging the locking projection 31 of the button 30 and the rib 21 of the outer lid 20 with each other. Therefore, in this embodiment, the structure in which the locking projection 31 of the button 30 and the rib 21 of the outer lid 20 are engaged with each other is omitted as shown in FIG.

According to the lid with a dropper of the present embodiment, the outer lid 20 and the button 30 rotate integrally with each other during the lid closing operation or the lid opening operation, and idle with respect to these outer lid 20 and button 30. By the action of the guide groove 15 of the inner lid 10 and the locking projection 31 of the button 30, the button 30 is given a downward movement or an upward movement, and the elastic suction body 13 is pressed or released so that the liquid content is elastic. It is sucked into the suction body 13. After the lid is opened, the button 30 is pushed down to push the elastic suction body 13 and the liquid content is poured out.

According to the present embodiment, by making the outer lid 20 and the button 30 non-circular in outer shape, it is not necessary to engage the locking projection 31 of the button 30 and the rib 21 of the outer lid 20 with each other. .. As a result, it is not necessary to provide a vertical groove for engagement in the rib 21, so that the shape of the inner peripheral surface of the outer lid 20 is simplified and the outer lid 20 is easily formed. Further, even when the button 30 is assembled inside the inner lid 10, it is not necessary to engage the locking projection 31 of the button 30 with the rib 21 of the outer lid 20, so that the button can be simply assembled. The assemblability of is improved. This contributes to a reduction in manufacturing cost of the lid with a dropper.

In the third embodiment, the lid with a dropper having a rectangular outer shape is illustrated, but the same effect can be obtained if the outer shape is a non-circular shape in plan view. For example, a rectangular shape or an elliptical shape in plan view. It can be widely applied to lids with a dropper such as shapes and diamonds, and can also be widely applied as lids for bottles of various shapes.
