A trigger-type ejector includes: a pressure storage chamber formed in a nozzle head and communicating with a flow path through a communication hole; a pressure storage plunger including a large-diameter pressure receiving portion opposite a small-diameter pressure receiving portion and being movable between a close position where an ejection hole is closed and an open position where the ejection hole is opened; and a biasing member disposed in the pressure storage chamber and biasing the pressure storage plunger toward the close position, the trigger-type ejector being configured such that, when a pressure of a liquid in the pressure storage chamber becomes equal to or greater than a predetermined value, the pressure storage plunger moves from the close position to the open position against a biasing force of the biasing member and thus a liquid in the pressure storage chamber is ejected from the ejection hole to the outside.

Trigger-type ejector

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.

Trigger-type liquid dispenser

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.

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.

A shoulder cover for an aerosol container that can be readily positioned and attached to the aerosol container having two stems. The shoulder cover is attached to a mounting cup that includes an upper tier part having two stems protruding from a top wall thereof and having long sides and short sides, and a cylindrical part. The shoulder cover includes an outer circumferential wall, a roof wall, a cylindrical wall extending downward from the roof wall, and locking structure provided to the cylindrical wall and retaining the shoulder cover by engaging with the cylindrical part of the mounting cup, and positioning structure for fitting with the upper tier part to thereby position a mating position of the shoulder cover is formed.

When a decoding circuit () decodes an instruction code stored in a pipeline register (), the decoding circuit () decodes the device address. Based on this, it is decided which one of the device information of a RAM () and a RAM () is to be used. When the area of the RAM () has been assigned, the decoding circuit () outputs a signal showing that the number of stop of pipeline processing is 0, unlike the assignment of the RAM (). Therefore, a pipeline register section () does not set the pipeline stop signal to 1. Consequently, the reading of the instruction code from the RAM () and the pipeline processing are not interrupted. As a result, it is possible to realize a structure in which execution of a high-speed processing is possible and a compact/low-cost structure in the same hardware.
