  The lower half portion 40 a of the outer peripheral wall 40 is screwed into the outer surface of the mouth and neck portion 6, and the upper half portion 40 b of the outer peripheral wall 40 is erected above the substrate portion 22. The upper half 40 b shown in the drawing has an outer diameter smaller than that of the lower half. At the upper end portion of the inner surface of the outer peripheral wall 40, an upward outer fitting step portion S1 is circumferentially provided. An air gap A is formed between the outer peripheral wall 40 and the substrate portion 22 to communicate a space G described below to the lower side of the lid base 18.

  The inner peripheral wall 50 is connected to the upper half 40 b of the outer peripheral wall 40 via a suitable number of connection pieces 48 so as to be positioned with a certain gap G. At the upper end of the outer surface of the inner circumferential wall 50, an inner fitting step S2 is circumferentially provided to face the outer fitting step S1. The connection piece 48 is intermittently provided in the circumferential direction so as to connect an appropriate position (lower end in the illustrated example) of the inner peripheral wall 50 below the inner fitting step S2 and the upper half of the outer peripheral wall 40 It is also good. The cut piece 26 of the locking wall portion 24 is inserted through the connection piece 48, and functions as an anti-rotation member of the lid base with respect to the movable lid.

  The flange-like top wall 52 extends inwardly from the top of the inner circumferential wall 50. An appropriate number of vent holes 54 are opened in the inner peripheral portion of the flange-like top wall portion 52. Further, in the illustrated example, the outer peripheral portion of the flange-like top wall portion 52 is recessed in an annular shape, and the inside of the recessed wall portion 56 is formed such that a coil spring 70 described later can contact.

  The locking cylindrical portion 58 is suspended from the inner edge of the flange-like top wall portion 52, and an annular engagement claw 58a attached to the inner surface of the lower end portion of the locking cylindrical portion 58 moves up and down into the engagement recess 32a of the dropper tube 30.

  In the assembly process of the lid 16, after the lid base 18 is attached to the dropper tube 30 and the piston member 60 and the movable lid 38 are sequentially assembled, the lower end 72 a of the elastic dome 72 is placed in the upper gap G of the movable lid 38. Is inserted. Since the gap G communicates with the lower side of the lid base 18, it is possible to avoid the disadvantage that the lower end portion of the elastic dome 72 is lifted up without the air in the gap being released. In this state, the cover member 76 is further fitted to the outside of the outer peripheral wall 40, and the pressed surface 74 of the lower end portion 72a is pressed by the pressing portion 80 of the cover member 76.

When using the above-mentioned dropper container, the outer peripheral wall 40 is rotated together with the cover member 76 (see FIG. 3) and screwed off from the neck 6. Then, the movable lid 38 ascends by the elastic force of the coil spring 70, and the air in the elastic dome 72 is sucked into the space between the movable lid 38 and the lid base 18, and the liquid in the container 4 is the dropper tube 30. It is sucked up inside. After that, the lid 16 can be pulled up from the container 2 side, and the elastic dome 72 can be squeezed to drip the liquid from the dropper tube 30.

Subsequently, a dropper container according to a second embodiment of the present invention will be described. Hereinafter, only the configuration different from the dropper container according to the first embodiment described above will be described, and the same configuration as the dropper container according to the first embodiment is denoted by the same reference numeral, and the description thereof will be omitted.

FIG. 4 is an enlarged view of a main part of a dropper container according to a second embodiment of the present invention. FIG. 5 is a view looking up the packing of FIG. 4 from below. FIG. 6 is a partially enlarged view of FIG.
In the process of assembling the lid 16, with the coil spring 70 interposed between the bottom wall 64 and the flange-like top wall 52, the piston 66 is slid upward on the inner surface 50 A of the inner circumferential wall 50. At the same time, the locking cylindrical portion 58 of the movable lid 38 is inserted into the inner cylindrical portion 62A of the piston member 60. The locking projection 58b of the locking cylindrical portion 58 is climbed upward by the temporary fixing projection 62C provided on the inner surface 62AA of the inner cylindrical portion 62A, whereby the single piston member 60 is temporarily fixed to the movable lid 38. .
Thereafter, the assembly in which the lid base 18 and the dropper tube 30 are assembled is assembled to the movable lid 38. At this time, with the upper portion of the base cylinder portion 20 of the lid base 18 fitted in the lower portion of the leg cylinder portion 68 of the piston member 60, the piston member 60 and the coil spring 70 are vertically compressed. The movable lid 38 is raised by a predetermined amount while being deformed. Then, the engaging claw 58a of the locking cylinder 58 is advanced into the engaging recess 32a of the dropper tube 30. At this time, or thereafter, the biasing force of the coil spring 70 pushes the piston member 60 against the movable cover 38, and the base cylinder 20 is fitted in the leg cylinder 68 over the entire length in the vertical direction.

A member composed of the inner circumferential wall 50, the flange-like top wall 52, the depressed wall 56, and the locking cylinder 58 is referred to as a cylinder 100.
In a locking cylindrical portion 58 corresponding to the inner peripheral wall of the cylinder portion 100, a valve body 27 for closing the upper end opening of the dropper tube 30 is provided. The valve body 27 is disposed on the central axis of the container body 4 and is connected to the upper end of the locking cylinder 58 via the bridge 29. A plurality of bridge portions 29 are arranged at intervals in the circumferential direction. In the dropper tube 30, as described later, when the movable cover 38 ascends with respect to the dropper tube 30 and the upper end opening of the dropper tube 30 is opened by the valve body 27, it communicates with the space in the elastic dome 72 . That is, the inside of the dropper tube 30 can communicate with the space in the elastic dome 72.

When using the above-mentioned dropper container, the outer peripheral wall 40 is rotated together with the cover member 76 (see FIG. 3), and the movable lid 38 is screwed out of the neck 6. Then, the movable lid 38 ascends by the elastic force of the coil spring 70, and the air in the elastic dome 72 is sucked into the space between the movable lid 38 and the lid base 18, and the valve body 27 opens at the upper end of the dropper tube 30. The liquid in the container body 4 is drawn into the dropper tube 30 in order to open the container. After that, the lid 16 can be pulled up from the container 2 side, and the elastic dome 72 can be squeezed to drip the liquid from the dropper tube 30.
According to this dropper container, as described above, the movable lid 38 is detached from the container body 4 and the contents are poured out from the dropper tube 30. Thereafter, when the movable lid 38 is attached to the container body 4, the movable lid 38 is lowered relative to the lid base 18, whereby the piston 66 of the lid base 18 is moved within the cylinder 100 of the movable lid 38. It slides relatively upward to reduce the internal volume of the cylinder portion 100.
At this time, a crush projection 28 b is formed on the lower surface of the packing 28 disposed between the lid base 18 and the upper end opening edge of the neck 6 of the container body 4. (See Figures 5 and 6). Therefore, a communication gap 28 c is formed between the lid base 18 and the upper end opening edge of the container body 4 for communicating the inside and the outside of the container body 4 (see FIG. 6). Therefore, the reduction of the internal volume of the cylinder portion 100 described above is exhausted to the container body 4 through the air hole 54, the space in the elastic dome 72, the inside of the dropper tube 30, the inside of the container body 4 and the communication gap 28c. The increase in internal pressure of 4 is suppressed. Thereby, regardless of the remaining amount of the content in the container body 4, the suction amount of the content to the dropper pipe can be accurately constant.
Thereafter, by lowering the movable cover 38 further, the packing 28 is pressed between the cover base 18 and the upper opening edge of the container 4, and in particular, the crush projection 28 b is formed on the upper opening edge of the container 4. Crushed (see Figure 4). At that time, since the overhanging recess 28d is formed immediately above the crushing projection 28b, the overhanging recess 28d allows the deformation of the crushing projection 28b to the upper surface side (see FIGS. 5 and 6). ). Therefore, the upper side of the crush projection 28b smoothly occurs without much resistance. Thereby, the sealability between the lid base 18 and the upper end opening edge of the container body 4 by the packing 28 is well secured.
Moreover, in the above-mentioned dropper container, the valve body 27 closes the upper opening of the dropper tube 30 in the initial state. Therefore, for example, even if the lid 16 is operated unintentionally in the initial state, it is possible to prevent the contents in the container body 4 from erroneously flowing into the dropper tube 30. Therefore, the amount of pouring of the contents from the dropper tube 30 can be accurately maintained constant. Furthermore, even if, for example, the contents of the container body 4 flow into the dropper tube 30 due to the drop of the dropper container in the initial state, the contents can be blocked by the valve body 27. Therefore, the content can be restricted from flowing into the space in the elastic dome 72.

  According to the present invention, the lower end portions of the elastically deformable members are inserted into the upper ends of the outer peripheral wall and the inner peripheral wall, which are disposed with a gap therebetween, compared to the case where the elastically deformable members are inserted into the fitting grooves. The repulsion of the air is reduced, the insertion operation can be smoothly performed, and the dropper container having a good setting property can be provided.
