Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial field of application" The present invention relates to a knock-type liquid ejection container for ejecting liquid cosmetics such as perfume.

"Prior Art" In this type of container, a cap to be fitted on a nozzle portion or the like is detachably attached to a mouth portion or the like of a container body by screwing or snapping.

"Problems to be solved by the invention" However, in the above-mentioned conventional container, in addition to the operation of attaching / detaching the cap, it is necessary to pay attention to the storage of the removed cap, which is troublesome to use.

Therefore, an object of the present invention is to provide a liquid ejection container which does not require a cap attaching / detaching operation and is convenient to use.

[Means for Solving Problems] In order to achieve the above object, the liquid ejection container according to the present invention has an outer cylinder 4 having upper and lower end surface openings, and the lower end surface of the outer cylinder is A cover member 1 closed by a cover plate 6 having a substantially L-shaped cross section attached to the outer surface of the lower part through a leaf spring 5;
From inside the liquid storage container body 11 that is stored in the outer cylinder in an inverted state and can be moved up and down, push the valve opening type stem 13 downward through a mouth located at the lower end of the container body, and It consists of an elevating member 2 that is watertightly hung and a nozzle cylinder 14 is fitted to the lower end of the stem, and a spring 3 that urges the container body upward. Engaging means 8 and 17 for restricting the lower limit position of the nozzle cylinder are provided on each of the facing surfaces, and the container body is pushed down to the lower limit position of the nozzle cylinder against the outer cylinder to resist the bias of the leaf spring. The lid plate 6 is pushed open so that the lower end of the nozzle cylinder projects downward from the cover member, and the container body is further pushed down from this state, so that the stem is pushed into the container body so that the valve can be opened. Is characterized by.

[Operation] For example, when the container body 11 is pushed down from the state shown in FIG. 1 to the outer cylinder 4 until the engagement means 17 on the nozzle cylinder 14 side engages with the engagement means 8 on the outer cylinder side, a plate is formed. The lid plate 6 is pushed open against the urging force of the spring 5, and the lower end of the nozzle cylinder projects below the cover member 1. That is, the lower end opening of the nozzle cylinder is opened.

When the container body is further pushed down from the above state, as shown in FIG. 3, the stem 13 is pushed into the container body to open the valve, and the liquid in the container body is ejected through the stem and the nozzle cylinder.

When the pushing down of the container body is released, the elevating member 2 rises due to the urging of the spring 3, the lower end of the nozzle cylinder is sunk into the outer cylinder, and the cover plate urges the lower end surface of the outer cylinder due to the urging of the leaf spring. To block.

[Example] An example of the container of the present invention will be described below with reference to the accompanying drawings.

1 to 3, 1 is a cover member, 2 is an elevating member, and 3 is a return spring.

The cover member 1 has an outer cylinder 4 which is open at both upper and lower end surfaces, and a lower end surface of the outer cylinder 4 is attached to a lower outer surface of the outer cylinder 4 by a leaf spring 5.
It is closed by a lid plate 6 having a substantially L-shaped cross section attached through the.

In the illustrated example, the lower end surface of the outer cylinder 4 is formed as a forwardly inclined surface, and a shallow groove 7 for fitting the cover plate 6 is bored from the lower end surface to the lower front surface. Further, an inward flange-shaped portion 8 as an engaging means is attached to the inner edge of the lower end of the outer cylinder 4. Further, a guide groove 9 is vertically provided on the inner surface of the upper portion of the outer tube 4, and a holding tube 10 is fitted on the inner edge of the upper end of the outer tube 4.

The elevating / lowering member 2 has a valve opening type stem 13 pushed in from a liquid storage container body 11 accommodated in the outer cylinder 4 in an inverted state and capable of moving up and down through a mouth portion 12 located at a lower end of the container body 11. The stem 13 is urged downward and is made watertight.
The nozzle cylinder 14 is fitted to the lower end of the. The container body 11 may be an aerosol container or may have a pump mechanism.

In the illustrated example, the push button 15 is connected to the upper end surface of the container body 11, and the lower half of the push button 15 is fitted into the holding cylinder 10 so as to be vertically slidable. The front and rear portions of the lower end of the push button 15 are provided with eaves-shaped portions 16, 16 for fixing plates, and the eaves-shaped front portion 16 of them is fitted into the guide groove 9. Further, the lower end surface of the nozzle cylinder 14 is formed in a hemispherical shape, and a flange portion 17 as an engaging means is provided on the upper outer surface.
Are laid around.

The return spring 3 includes the shoulder portion of the container body 11 and the outer cylinder 4.
It is interposed between the inwardly facing flange-shaped part 8 and the container body 11 to urge it upward.

In the container of the present invention, the container body 11 is attached to the outer cylinder 4.
Is pushed down to the lower limit position of the nozzle cylinder 14 (that is, until the lower surface of the collar portion 17 engages with the upper surface of the inward flange-shaped portion 8) to push the lid body 6 against the bias of the leaf spring 5. When the nozzle cylinder 14 is opened and the lower end of the nozzle cylinder 14 projects downward from the cover member 1, and the container body 11 is further pushed down from this state, the stem 13 is pushed into the container body so that the valve can be opened.

In the above-described embodiment, each part is molded and manufactured from a synthetic resin material except the return spring 3 and the like.

[Advantages of the Invention] As described above, according to the present invention, the lid plate connected to the outer cylinder is configured to automatically open and close according to the raising / lowering movement of the container body with respect to the outer cylinder. There is no need to open and close, and you don't have to worry about storing the lid plate when opening the lid.
It is very convenient to use.

Claims (1)

[Scope of utility model registration request] 1. An outer cylinder 4 having upper and lower end surfaces opened,
A cover member 1 in which a lower end surface of the outer cylinder is closed by a cover plate 6 having a substantially L-shaped cross section attached to a lower outer surface of the outer cylinder via a leaf spring 5, and a cover member 1 which is in an inverted state in the outer cylinder and From the inside of the liquid storage container 11 that can be lifted up and down, the push-opening valve-type stem 13 is urged downward through the opening located at the lower end of the container body to cause it to hang downward in a watertight manner. It is composed of an elevating member 2 having a lower end fitted with a nozzle cylinder 14 and a spring 3 for urging the container body upward. By providing the engaging means 8 and 17 for restricting the above, and pushing down the container body to the lower limit position of the nozzle cylinder with respect to the outer cylinder, the cover plate 6 is pushed open against the bias of the leaf spring. The lower end of the nozzle cylinder projects downward from the cover member, and the container body is further pushed down from this state, whereby the above-mentioned step is performed. Liquid ejection container but which is characterized by being pushing the container body was opened can be formed.
