摘要： A trigger-type liquid dispenser that, even when lateral force is applied to a trigger, prevents liquid leakage. The trigger-type liquid dispenser includes a pump, which includes: a cylinder, which includes an inner tubular wall and an outer tubular wall; a piston, which has a front-side end portion; a front-side sealing piece and a rear-side sealing piece; an outer-circumferential-side support portion; and an inner-circumferential-side support portion. The outer-circumferential-side support portion is provided with an annular cut-off portion, which forms a gap between the outer-circumferential-side support portion and an outer circumferential surface of the piston.

摘要： A trigger-type liquid dispenser includes a dispenser main body, pump, and nozzle. The body includes a fitted portion, which communicates with a delivery port. The nozzle includes a partition wall, which covers an opening end of the fitted portion and has a dispensing hole, and an outer circumferential wall. The nozzle is rotatable with respect to the fitted portion between an opened position, wherein the hole communicates with the port, and a closed position, wherein the hole is blocked. The outer circumferential wall includes a locking projection, in undercut engagement with a projecting portion, on an outer surface of the fitted portion, to hold the nozzle in engagement with the fitted portion. The locking projection, in an inner edge portion thereof, has a concave portion, wherein the degree of undercut engagement with the projecting portion is reduced when the nozzle is located between the opened and the closed position.

摘要： A trigger-type liquid dispenser, in which an upright and inverted dual unit includes a joint member, a pipe holding member, and a valve body. The joint member includes a through hole, which may be closed by the valve body, a valve-body-holding wall portion, which accommodates the valve body above the through hole in a manner such that the valve body is displaceable upward and downward, and an opening portion, which is formed in the valve-body-holding wall portion. In the inverted position, the upright and inverted dual unit permits content liquid contained in a container to be supplied to the dispenser main body by passing content liquid through a flow path from opening portion, through the hole, to the flow path defined between the joint member and pipe holding member sequentially. The valve body is inserted through the opening portion to be accommodated in the valve-body-holding wall portion.

摘要： A trigger-type liquid dispenser includes valve member, which is provided in flow path to control liquid to flow in direction in flow path. Valve member includes intake-side check valve, which permits flow of liquid from container side to pump side and prevents flow of liquid from pump side to container side, and discharge-side check valve, which permits flow of liquid from pump side to nozzle side and prevents flow of liquid from nozzle side to pump side. Discharge-side check valve is formed in umbrella shape that is elastically deformable freely in radial direction and has outer circumferential end configured to contact inner circumferential surface of flow path, with contact force of outer circumferential end with respect to inner circumferential surface of flow path being distributed non-uniformly in circumferential direction.

摘要： Provided is a trigger-type liquid dispenser (1) including an operating lever (6) held swingably by a main body portion (3) in which a pump is disposed and including a spring member (7) that imparts restoring force to the operating lever (6). The trigger-type liquid dispenser (1) is configured to draw, pressurize, and force-feed a content liquid contained in a container (C) to dispense the content liquid through a nozzle (5), by actuating the pump in response to the operating lever (6) being pulled repeatedly. The spring member (7) is held swingably with respect to the main body portion (3), and, in response to the operating lever (6) being pulled, the spring member (7) undergoes elastic deformation and swings with respect to the main body portion (3).

摘要： A makeup liquid container with an applicator includes: a container body 1 having a barrel portion 8 and an open neck portion 6; a cap 4 designed to be screwed to the open neck portion 6 of the container body 1; a squeezing sleeve 3 fitted in the open neck portion 6 of the container body 1; and an applicator shaft 5 extended downward from the cap 4 into the container body 1 through the squeezing sleeve 3. A stirrer 9,91 is rotatably disposed in the barrel portion 8 in sliding contact with the inner surface of the barrel portion 8. An engaging device provides a driving connection between the cap 4 and the stirrer 9,91 in such a manner that the stirrer 9,91 is rotated when the cap 4 is rotated in the screwing and/or unscrewing direction and that the driving connection between the cap 4 and the stirrer 9,91 is dismissed when the applicator shaft 5 is extracted from the container body 1.

摘要： A synthetic resin tube container is formed to have a shortened neck portion and to eliminate an overlapping double wall in a structure for mounting a cap to the neck portion. The tube container comprises a container body and a cover plate. The container body has a trunk portion from which the neck portion is extending upwardly through an inward flanged wall. The upper surface of the neck portion is closed by a top wall with a discharge port. A fitting recessed groove is formed circumferentially on the inward flanged wall. The cover plate is connected via a hinge to an insert cylinder which is fitted into the fitting recessed groove.
