Description

[Detailed Description of the Invention] The present invention relates to a liquid ejection container such as an atomizer or a foam ejector.

This kind of container has a stem erected from a pump mounted inside the container body, an operating head with a nozzle hole is fitted to the upper end of the stem, and liquid inside the container is sucked up by the pump by vertical movement of the operating head.
Containers of this type that eject water from a nozzle hole are conventionally known, but the stem and operating head of this type of container have an extremely small outside diameter compared to the outside diameter of the container body, so the overall appearance of the container is unfavorable, and the operation is difficult. Since the head is relatively small, the position of the finger that presses down the operating head is close to the nozzle hole, and as a result, some of the sprayed mist or foam may adhere to the finger.

The present invention eliminates the above-mentioned drawbacks, and the embodiment shown in FIG. 1 will be described below. Reference numeral 1 indicates a container body. A mouth and neck part is erected from the upper end of the body part 2 of the container body via a shoulder part 3, and a stem 4 is erected from a pump installed in the container body, and a nozzle hole 5 is provided at the upper end of the stem. An operating head 6 is fitted therein. Reference numeral 7 designates a presser cap screwed onto the mouth and neck of the container body, and the stem passes through a through hole formed in the top wall of the cap. The stem is biased upward, and when the operating head is pushed down against this bias, the liquid in the pump cylinder turns into mist or foam and is ejected from the nozzle. When the operating head is released, the bias causes the stem and The operating head is pushed up, and at this time, the inside of the cylinder becomes negative pressure, and the liquid inside the container is sucked up into the cylinder through the suction pipe.

A cap 8 is fitted onto the top of the container. The cap has a window hole 10 for liquid ejection from the periphery of the top wall 9.
The lower part of the peripheral wall is a bellows-shaped surrounding wall portion 12, and the lower end portion 12a of the bellows-shaped surrounding wall portion is provided vertically.
is fitted into a groove 2a provided around the outer surface of the upper end of the body of the container. The bellows-shaped peripheral wall portion may be formed as separate members and connected as shown in the drawing. An engaging tube 13 is provided hanging from the back surface of the top wall of the cap, and the operating head 6 is fitted into the engaging tube, and a protrusion 9a is provided hanging from the back surface of the center portion of the top wall, and the lower end of the protrusion is is in contact with the top wall of the operating head. The nozzle hole 5 of the operating head is provided facing the window hole so that mist etc. jetted through the nozzle hole can be jetted outward through the liquid jetting window hole of the cap. The engagement tube may be opened at the front portion of the nozzle hole. A groove 13a is provided in a part of the inner wall surface of the engagement tube, and an engagement element 6a attached to the outer surface of the operating head is fitted into the groove to prevent misalignment between the window hole and the nozzle hole. It is prevented.

In the embodiment shown in FIG. 2, an outward flange 12b is attached to the lower end of the bellows-shaped peripheral wall portion 12, and the flange is placed on the outer circumference of the shoulder of the container body, and an engaging ring 14 having an inward channel-shaped cross section The lower flange 14a of the engaging ring is engaged with the groove 2a provided around the upper end of the container body body, and the upper flange 14b is engaged with the upper surface of the outward flange of the bellows-shaped peripheral wall. ing.

In the embodiment shown in FIG. 3, the fitting wall is connected from the outer peripheral edge of a tapered wall 7a that slopes downward and outward along the shoulder of the container body from the lower end of the peripheral wall of the presser cap 7 to be screwed onto the neck of the container body. 7b is erected and the lower end of the bellows-shaped peripheral wall is fitted into the fitting wall.

In this case, the cap 8 having the bellows-shaped circumferential wall part 12 at the lower part of the circumferential wall is fitted onto the upper part of the container, and the lower end of the bellows-shaped circumferential wall part is connected directly or indirectly to the upper end of the body of the container. Because they are connected, the stem and operating head, which have a significantly smaller diameter than the body of the container, are hidden inside the cap, thereby improving the appearance of the liquid ejecting container. Since the cap is connected to the upper end of the body, the cap will not come off from the container body, and the operating head can be pushed down through the cap by the expansion and contraction of the bellows-shaped peripheral wall. Rather than pressing down, the device is pressed down through a cap with a larger diameter than the head, which allows the distance between the liquid ejection window hole and the finger to be greater, thereby eliminating the problem of mist adhering to the finger. Since the top wall of the cap is wider than the top surface of the operating head, the above-mentioned pressing down can be performed easily.
