Description

[0001]
BACKGROUND OF THE INVENTION
The present invention is a vertical pump type, that is, a cylinder is suspended by a mounting cylinder screwed into the outer surface of the container body neck and neck, and the cylinder is suspended from the inside of the container. The present invention relates to a liquid ejection container which is provided with an actuating member having a lowering head standing upright, and by vertically moving the actuating member, liquid in the container is ejected into the cylinder and liquid in the cylinder is ejected from the nozzle.
[0002]
[Prior art]
Since the liquid ejecting container is erected with the actuating member biased upward, the upper part of the actuating member is obstructed during transportation. A member was fitted, and the operating member was pushed down against the bias, and the upper part of the operating member was screwed into a female screw provided on the inner surface of the cylindrical member.
[0003]
[Problems to be solved by the invention]
However, in the above case, when the upper part of the operating member is screwed off from the cylindrical member and the operating member is lifted by urging, the female screw hole of the cylindrical member forms an annular recess in the upper surface opening. When used in a place where it is frequently used, the hot water that has entered the annular recess may travel through the operating member and enter the container to dilute the liquid in the container.
[0004]
In order to eliminate the above disadvantages, as shown in FIG. 3, the screw of the cylindrical member 41 is provided on the outer surface of the outer cylinder 43 as a male screw 42 and screwed with the outer peripheral wall of the pressing head, and the inner diameter of the inner cylinder 45 of the cylindrical member is set. It was considered that the outer diameter of the operating member portion 46 inserted into the inner cylinder was considered to be approximately the same as the outer diameter, but in this way, when the mounting cylinder 49 is rotated for screwing from the container body, the cylinder 48 In addition, the cylindrical member 41 and the pressing head 47 may rotate together, making it impossible to rotate only the mounting cylinder with respect to the cylinder or the like.
[0005]
The liquid ejection container is sent from the container molding maker to the liquid maker in a set state, and the liquid maker removes the liquid ejector as a pump and pastes a label or the like on the container body and fills the liquid. Since the ejector is reset and shipped to the market, if it becomes impossible to rotate the mounting cylinder 49 with respect to the cylinder 48, the pressing head 47, etc. as described above, the shape of the container body or the After the nozzle protruding direction is determined by matching the position of the label affixed to the body portion, it is impossible to turn only the mounting cylinder 49 and tighten it as it is. As described above, when the mounting cylinder 49 cannot be rotated with respect to the cylinder, the pressing head or the like and is put into the consumer's hand, the consumer raises the operating member from the cylinder 48 by screwing only the pressing head. That is, the liquid ejection operation cannot be performed.
[0006]
This phenomenon occurs when the pressing head 47 made of synthetic resin is fastened to the cylindrical member 41 made of synthetic resin. Rib for positioning the lower limit of the outer peripheral wall 44 of the pressing head, which is provided above the insertion portion into the inner cylinder before reaching the hand of the liquid manufacturer or before reaching the hand of the consumer from the liquid manufacturer 50 pushes down the inner peripheral portion of the top wall of the tubular member 41 and pushes up the top wall of the push-down head 47 to cause deformation, so that the lower end surface of the press-down head outer peripheral wall 44 faces the upper end of the mounting cylinder 49 This is considered to be caused by pressure bonding to the upper surface of the flange 49a.
The object of the present invention is to eliminate the above-mentioned drawbacks.

【The invention's effect】
The present invention has the above-described configuration. In the case of the liquid ejection container according to claim 1, the screw of the cylindrical member 31 with the synthetic resin screw that is non-rotatably fitted to the upper end of the cylinder 5 is provided. A male screw 19 is formed on the outer surface of the outer cylinder 34 of the cylindrical member 31 as the male screw 33, and a female screw 19 provided on the lower inner surface of the pressing head outer peripheral wall 18 made of synthetic resin is screwed to the male screw. Since an appropriate number of ribs 20 are vertically arranged on the wall portion inner surface at substantially equal intervals and a downward stepped portion 20a formed by the lower surface thereof is pressed against the upper surface of the outer peripheral portion of the top wall 32 of the cylindrical member 31, the cylindrical member Even if distortion or stress remains in the screwed portion by screwing and tightening the outer peripheral wall 18 of the push-down head 31 to the outer cylinder 34, a downward stepped portion 20a is formed on the outer peripheral wall portion above the female screw 19 of the outer peripheral wall 18. And the downward stepped portion is pressed against the upper surface of the outer peripheral portion of the top wall, which is also the upper end surface of the outer cylinder 34 of the cylindrical member 31. Therefore, the outer peripheral wall 18 of the push-down head does not descend with respect to the outer cylinder 34 of the cylindrical member 31 due to the above-described distortion or the like. Therefore, the lower end of the outer peripheral wall 18 with respect to the outer cylinder 34 is lowered. Can be prevented from coming into pressure contact with the upper surface of the inward flange 4 of the mounting cylinder 3 so that the push-down head 15 cannot be unscrewed.
[0013]
In the case of claim 2, in addition to the above effects, the outer diameter of the actuating member part inserted through the inner cylinder 36 of the cylindrical member 31 so as to be movable up and down is substantially the same as the inner diameter of the inner cylinder 36. Even at the time of unscrewing, the annular recess as in the conventional example is not formed on the inner periphery of the upper end of the inner cylinder 36, so that water or the like enters the container from the recess to dilute the liquid in the container. There is nothing.
