Description

[Detailed Description of the Invention] (Industrial field of application) The present invention is equipped with a dropper on the lid that covers the mouth of the container body, and can be used for storing chemicals, cosmetics, fragrances, etc. contained in the container body. The present invention relates to a container with a dropper that sucks up liquid little by little and takes it out.

(Prior Art) In order to take out the liquid contained in the container little by little,
Instead of preparing a dropper separately from the container, the lid is equipped and integrated, but the lid is attached to the container by screws as seen in Japanese Utility Model Publication No. 56-5579. It is necessary to completely screw the lid body so that the tip of the pipette can reach near the bottom of the container body when the remaining amount of the liquid becomes low.Each time it is taken out, the lid body is rotated and separated from the container body and screwed again. It is extremely troublesome because it must be done.

Therefore, a container with a dropper that can be separated from the container body by simply disengaging the lid body from the container body in conjunction with the push button for operating the dropper and pulling up without rotating the lid body was developed. -199963 publication.

In these, the push button or the lid itself is provided with an elastic engaging piece extending in the axial direction of the container and engaged with the outer peripheral surface of the neck portion of the container body, and when the push button is pressed, the elastic engaging piece is outwardly moved. It is bent and disengaged.

However, since these are still disengaged even when the push button is released, if the push button is pressed by mistake, the container body opening will open and the contents will evaporate or flow out. I'm worried. In addition, since the lid body is held in the container body by the elastic engagement piece being hooked on the outer peripheral surface of the mouth and neck, it is unstable and easily rattles, and is inadvertently removed when tilted. There is also a concern.

(Problems to be solved by the invention) The present invention has a structure in which the lid body and the container body are disengaged with one touch by pressing a push button, and the dropper tube can be easily reached even when the remaining amount is low. It has the above-mentioned container with a dropper that can be used, there is a concern that the lid may come off from the container body if the push button is pressed carelessly, and the holding state of the lid body on the container body may be unstable and it may come off. , Which is lacking in reliability, returns to the engaged state when the push button is released and returns to the engaged state, and not only the lid is stably held on the container but also the elastic engaging piece is secured with a small force. An object of the present invention is to provide a container with a dropper that is bent and bent and can be removed from the container body with excellent operability.

(Means for Solving the Problems) In order to solve the above problems, a container with a dropper according to the present invention includes a lid body having a tubular outer lid and an inner lid that are fixed to each other at a lower end thereof; A dropper tube that is axially movably attached to the lid body through a through hole provided in the plate, and a dropper having a head body that closes the base end thereof to form a variable volume suction chamber; A plurality of elastic locking pieces that are separately formed and extend outward and upward and that have a base fixed to the inner lid and that surrounds the mouth and neck of the container; A push button having a tubular bending piece for pushing the pressing portion, the push button being axially movably fitted into a fitting opening provided in the top plate of the outer lid; and provided on an outer peripheral surface of the mouth / neck portion. And a locking groove; The lid body is attached to the container body by covering the mouth and neck with the inner lid and covering the mouth and neck with the elastic engagement piece fitted into the locking groove. When the push button is pushed, the head body is pushed to shrink the suction chamber, and at the same time, the bending piece moves almost in contact with the outer peripheral surface of the inner lid to push the pressing portion to push the elastic engaging piece to the outside. It is configured to be bent in one direction to be detached from the locking groove.

(Action) When the push button is pressed, the suction chamber shrinks to the minimum and at the same time the elastic engagement piece disengages from the locking groove, so the head body is restored by releasing the push button while pulling up the lid body and its reaction force. The dropper tube moves downward with respect to the lid body, and the liquid contained in the container body is sucked into the dropper tube while maximizing the volume of the suction chamber. Further, the lid body is pulled up to pull out the dropper tube from the container body, and the push button is pushed to take out the liquid. Further, the elastic engagement piece is fitted into the locking groove by covering the mouth and neck with the lid and pushing the lid a little, and the elastic engagement piece is attached to the container body with the opening of the mouth and neck closed. When the push button is pressed to release the lid without pulling it up, the elastic engagement piece restores and fits into the locking groove again, and the state in which the opening of the mouth and neck is closed is maintained.

(Effects of the Invention) According to the present invention, an elastic engaging piece that engages and disengages with a locking groove provided in the mouth and neck of a container body is provided in a lid body including an outer lid and an inner lid separately from the outer lid. , The elastic engagement piece is disengaged from the locking groove by moving the cylindrical bending piece extending from the push button for expanding and sucking the liquid by contracting and expanding the suction chamber of the dropper along the outer peripheral surface of the inner lid. Therefore, regardless of the outer lid that requires hardness, the elastic engaging piece can be provided with sufficient elasticity to release it securely and easily with a small force. It does not come off from the container body when rotated or pulled. Also, by pressing the push button to separate the lid body from the container body, and then releasing the push button while pulling up the lid body as it is, the liquid can be sucked into the dropper tube,
Moreover, since it is only necessary to move the lid body linearly in the axial direction, it is convenient to continuously take out the liquid. In addition, when the push button is pressed to release the lid without pulling it up, the elastic engaging piece fits into the locking groove again, so that even if it is pressed by mistake, the opening opens and the liquid evaporates or flows out. Moreover, since the inner lid circumscribes the mouth and neck and covers it, the lid body is stably attached to the container body without rattling, and there is no concern that the elastic engagement piece will come off due to tilting, providing high reliability.
