Description

[Detailed explanation of the idea] This case concerns a container with a dropper.

Conventionally, the dropper attached to a specific container body is sometimes too long or too short for the container body. In order to be able to insert the dropper nozzle into the liquid,
When the dropper is removed, the liquid adhering to the outer surface of the nozzle may drip off, and if the length is too short, there is a waste of liquid that cannot be sucked in when the dropper is used.

The present invention eliminates the above-mentioned drawbacks and makes it possible to freely adjust the insertion length of the dropper nozzle into the container body.To explain the drawings below, 1 shows a container with the mouth and neck part 2 erected upward. A dropper 3 is attached to the mouth and neck of the container body. The dropper 3 is formed by a main cylinder and a liquid suction member.

The main cylinder 4 has a peripheral wall 5 whose lower half is screwed into the neck of the container body, and an inward flange-like wall 6 projects from the inner surface of the middle part of the peripheral wall, and from the inner peripheral edge of the inward flange-like wall, the A screw tube 7 is vertically disposed on the same axis as the peripheral wall, and the screw tube has a thread on its inner surface. It is preferable to fit a short elastic tube 8 for squeezing the outer surface of the nozzle, which will be described later, into the lower end of the screw tube. A packing 9 is fitted in the upper inner part between the lower half of the peripheral wall and the upper end of the spiral cylinder, and the lower surface of the inwardly flange-shaped wall is brought into pressure contact with the top surface of the mouth of the container via the packing.
An engaging protrusion 10 is provided on the inner surface of the upper end of the peripheral wall to prevent the liquid suction member described later from being pulled out.

The liquid suction member 11 has a nozzle 12 that is screwed into the spiral cylinder of the main cylinder and inserted into the container body, and has an outward flange-shaped wall 13 protruding from the upper end of the nozzle, and has a flange-shaped wall 13 that is slightly wider than the outer periphery of the wall. A large-diameter cylindrical portion 14 stands up from the inside, and a convex spherical thin elastic plate 15 made of rubber or the like is airtightly stretched over the upper opening surface of the large-diameter cylindrical portion. In order to prevent the elastic thin plate from coming off, a peripheral wall 16 may be provided hanging from the periphery of the elastic thin plate, and the peripheral wall may be fitted into the large diameter cylindrical portion 14. The lower part of the large-diameter cylinder part is rotatably fitted into the upper half of the main cylinder peripheral wall 5 described above, and when rotated in the forward direction, the screw cylinder and the nozzle are screwed together as described above. Since the liquid suction member is rotated in the opposite direction, the liquid suction member is lowered and raised when turned in the opposite direction. The outer periphery of the outward flange-like wall described above is the engagement protrusion 1 of the main cylinder peripheral wall 5
0, the large-diameter cylinder portion is prevented from being pulled out from within the main cylinder peripheral wall.

To take out the liquid inside the container, as with a normal dropper, a thin elastic plate formed into a convex spherical surface is pushed down against elasticity, and by releasing the pressure, the liquid is sucked into the nozzle and large diameter cylinder. Next, after removing the main cylinder circumferential wall from the container mouth neck, the elastic thin plate is pressed down to discharge from the nozzle. However, if the amount of liquid inside the container is large, turn the large diameter cylinder part in the opposite direction. It is used with the liquid suction member 11 positioned at the upper limit, and when the amount of liquid in the container decreases, the large diameter cylindrical portion is rotated in the forward direction to lower the liquid suction member.

The present invention has the above-mentioned configuration, in which the dropper is formed by a main cylinder and a liquid suction member, and the entire length of the dropper can be adjusted freely by turning the large diameter cylinder part of the liquid suction member in both forward and reverse directions. This eliminates the waste of discarding the container with a considerable amount of liquid remaining because the dropper is too short relative to the container, and the liquid in the container can be used almost completely, and the dropper is too long. However, by adjusting the length, it is easy to prevent the residue inside the container body from being sucked into the dropper.Furthermore, the length of insertion of the nozzle into the liquid can be adjusted, so that the outer surface of the nozzle can be adjusted by adjusting the length. The amount of liquid adhering to the nozzle can also be reduced, and the liquid adhering to the outer surface of the nozzle can be prevented from dripping when the liquid suction member is removed. Since the liquid suction member has a large-diameter cylindrical portion connected to the upper end of the nozzle, the inside of the large-diameter cylindrical portion can also be used as a suction liquid storage chamber, which is convenient in that the amount of liquid sucked at each time can be increased. .
