Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial Application Field" The present invention relates to a liquid ejection container.

"Prior Art" Conventionally, a liquid ejection container in which a cylinder type pump is attached to a container body in which a mouth and neck is erected is known. Cylinder type pumps for these containers have a stem that is vertically movable in an outer cylinder, and sucks and discharges liquid in the container by a valve mechanism provided below the stem and / or below the inner cylinder. Generally, however, a guide member for guiding the stem is provided at the upper end of the outer cylinder. The replacement air is introduced from between the guide member and the stem, and further passes between the inner surface of the outer cylinder and the outer surface of the stem, and the replacement air is introduced into the container body through a ventilation hole provided above the outer cylinder.

"Problems to be solved by the device" This type of container is often used in water areas such as bathrooms and washrooms. Therefore, the container may be covered with water or water droplets may adhere to the surface of the container due to condensation of water vapor. I often do it. In a conventional container of this type, water droplets attached to the container surface in this manner, particularly water droplets attached to the outer surface of the guide member, are introduced into the container body from between the stem and the guide member as the stem moves up and down. As a result, there arises a disadvantage that the liquid in the container body is diluted.

The present invention has been made in view of the above-mentioned drawbacks of the prior art, and an object of the present invention is to provide a liquid ejection container capable of preventing attached water droplets from entering the container body as much as possible.

"Means for Solving the Problem" A container body 2 in which a mouth / neck portion 5 is erected, a cap-shaped member 4 fitted to the outer periphery of the mouth / neck portion 5 and having an opening 8 in the center of a top wall 7 thereof, and the container body And a cylinder type pump 3 in which the lower end is housed in 2 and fixed at the mouth / neck 5 of the container body 2 by the cap-shaped member 4.
The cylinder type pump 3 has an outer cylinder 11 and a stem 12 that moves up and down inside the outer cylinder 11 and has a push-down head 14 with a nozzle 13 fitted on the upper end thereof. The stem is attached to the upper end of the protruding outer cylinder 11.
A tubular guide member 17 serving as a guide of 12 is fitted so as to cover the upper end of the outer cylinder 11, and a narrow groove 23 that descends outward from the center is formed on the outer surface of the guide member 17. .

[Operation] Even if water droplets adhere to the upper surface of the guide member 17, the adhered water droplets pass through the water droplet removing fine grooves 23 provided on the outer surface of the guide member 17 and drop onto the upper surface of the top wall 7 of the cap-shaped member 4. . Therefore, even if the stem 12 is moved up and down, there is no possibility that water droplets will enter the container body 2 from between the guide member 17 and the stem 12 and dilute the liquid in the container body 2.

[Embodiment] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

1 to 3 show one embodiment of the liquid ejection container of the present invention, in which 1 denotes the liquid ejection container. The container 1 is composed of a container body 2, a cylinder type pump 3 and a cap member 4.

The container body 2 is formed by erecting a mouth / neck portion 5, and a screw thread 6 is provided on the outer periphery of the mouth / neck portion 5. Also, the top wall 7 of the cap-shaped member 4
An opening 8 is provided at the center, and a thread 10 that is screwed with the thread 6 of the mouth / neck 5 is attached to the inner circumference of the peripheral wall 9.

The cylinder type pump 3 has an outer cylinder 11 and a stem 12 that moves up and down inside the outer cylinder 11, and a nozzle 13 is provided at an upper end of the stem 12.
This is a general cylinder type pump in which the attached push-down head 14 is fitted and which has an appropriate valve mechanism (not particularly shown) below the stem and / or below the inside of the outer cylinder.

A flange 15 is provided above the outer periphery of the outer cylinder 11 of the pump 3, and the flange 15 is sandwiched between the upper surface of the mouth / neck portion 5 of the container body 2 and the lower surface of the top wall 7 of the cap-shaped member 4, and thus the pump 3 is mounted. The container 2 is fixed at the neck 5 of the mouth. In the figure, 16 indicates packing. Further, the upper end of the outer cylinder 11 projects from the opening 8 of the cap-shaped member 4, and a cylindrical guide member 17 serving as a guide for the stem 12 is provided on the protruding upper end of the outer cylinder 11. The guide member 17 is fitted so as to cover the upper end of the outer cylinder 11, and a push-down head is provided above the inner surface of the inner peripheral wall 18.
14 A thread 20 is provided to be screwed with a thread 19 provided on the lower outer periphery, while a guide member 21 serving as a guide for the stem 12 is provided below the thread 20.
Has been extended. Reference numeral 22 in the figure denotes a replacement air passage hole provided in the outer cylinder.

Further, a plurality of fine grooves 23 for removing water droplets are formed on the outer surface of the guide member 17. The narrow groove 23 is formed over the exposed upper surface and outer peripheral surface of the guide member 17, and the upper surface is provided with an inclination that descends outward from the center. The number of the fine grooves 23 can be arbitrarily selected, but 4 to 20 is suitable.

When the container 1 configured as described above is used, the portion of the push-down head 14 is rotated to release the screw engagement between the screw 19 and the screw 20, and a coil spring (not shown) provided under the outer cylinder 11 is shown. ), The stem 12 rises along the guide portion 21 of the guide member 17. Then, when the push-down head 14 is pressed, the liquid in the container body 2 is ejected from the nozzle 13.

The present invention is not limited to the above-mentioned embodiment, and the material, structure, configuration and the like can be appropriately selected without changing the gist of the present invention.

For example, in the above embodiment, the narrow groove 23 is provided on the upper surface of the guide member with an inclination that descends outward from the center.
The inclination may be from the upper surface directly to the side surface, and the point is that it is an inclined narrow groove in which water droplets pass through the narrow groove and are removed onto the cap-shaped member or the like.

[Advantages of the Invention] As described above, the liquid ejection container of the present invention has the fine groove for removing water droplets formed on the outer surface of the guide member. Therefore, even if the container is accidentally covered with water, Water droplets adhering to the surface of the member are transferred to the upper surface of the cap-shaped member through the narrow groove, the water droplets are unlikely to enter the container body, and as a result, the content liquid is not diluted.
