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.

Shoulder cover for aerosol container

Provided is a nozzle cap for aerosol container that can be used for cleaning a nozzle of an aerosol container that has a plurality of stems, and preventing the nozzle from being pushed down. The nozzle cap includes a plurality of bar-like piecesthat can be inserted from ejection portsof a nozzleinto ejection-side communication passagesat least until distal endsreach upper endsof stem-like communication passages, and a lower protrusionthat prevents the nozzle from being pushed down by abutting on a cover memberbelow ejection tubesof the nozzlewhen the bar-like piecesare inserted into the ejection-side communication passages

Nozzle cap for aerosol container

Provided is a metered quantity syringe-type dispenser that is capable of multistage pushing. The metered quantity syringe-type dispenser includes a syringe; a plunger configured to be pushed into the syringe; an elastic deforming portion configured to be deformed in response to the pushing of the plunger; and a stopper portion configured to be locked with respect to the syringe and to be released from the locking by restoring force of the elastic deforming portion.

Metered quantity syringe-type dispenser

The fixing plate for an aerosol container includes: an outer wallthat covers a mounting cupexcept an openingexposing two stemsand abuts on an upper face of an annular rim; a cylindrical wallintegrally connected to the outer wallon a lower side thereof and surrounding the annular rim; and an engaging clawengaging the annular rim, wherein a positioning wallis provided at the opening, the positioning wall having an inner circumferential shape following an outer circumferential surface of a projectionthat protrudes from the mounting cup, with the two stemsbeing bound together, and that has a non-circular cross-sectional shape with long sides and short sides.

Aerosol container fixing plate

The dispenser assembly for an aerosol container includes a fixing platemounted to an aerosol containerthat has two stems, a nozzlefor discharging the contents via two connection partsthat respectively lead to the stemsand via one discharge tube, and a cover member covering the nozzleand held by engagement with the fixing plate. The cover member includes a lower coverhaving a first engaging piece, and an upper coverhaving a second engaging piece. The lower coverhas a pressing portionthat is supported via a hinge ha and pushes on the second engaging pieceto disengage the second engaging piece from the second engaging hole

Dispenser assembly for aerosol container

This invention makes it possible to spray liquid content while a cleaning member is mounted to a nozzle main body and remove residual liquid without pulling out the cleaning member from the nozzle main body. A nozzle includes a bodythat presses down two stemstogether, and a cleaning memberhaving two ejection portsand capable of moving relative to the body. The bodyis removably mounted to the stems, the cleaning memberis slidably inserted into an ejection-side passage Rand has two tubular parts. Each of the tubular partsforms a space Rthat connects a stem-side passage Rto an annular cross section passage Rwhen the cleaning memberis pulled out, while reduces this space Rto thereby remove a residual material C when the cleaning memberis pushed in.

Aerosol container nozzle and aerosol container dispenser

Provided is a syringe-type ejecting container that is capable of ejecting even a small amount of a content medium. Such an ejecting container includes an ejecting unit and an operation unit. The operation unit includes a syringe having a front end tubular portion, a rod extending through an inside of the front end tubular portion, and an operation shaft that causes the rod to project from the front end tubular portion. The ejecting unit includes a pipe that is mounted to the front end tubular portion and that is filled with a content medium, a plunger that is arranged inside the pipe, a nozzle that is mounted over an outside of a front end of the pipe, and a spin element that is arranged inside the nozzle close to the ejection hole and that is formed with a swirling groove leading to the ejection hole.

Syringe-type squirt container

An improved pump is provided that is capable of achieving excellent back suction function by using a depression head, without compromising the ease of depression operations of the head due to the additional function. The pump includes a depression head and an annular piston. The depression head is urged upward and is relatively displaceable with respect to the stem. When depressed, a lever member of the depression head operates to open a discharge opening. An annular piston opens a discharge valve, in an uppermost displacement position and closes the discharge valve in a lowermost displacement position. Back suction is caused due to a negative pressure state occurring in the stem until the discharge valve seat is closed by the annular piston during upward displacement of the stem.

Pump

A syringe has a dripless feature by using an O-ring located between a conical disc and a flat plunger disc in an annular groove on a moving plunger. The flat plunger disc has a series of projections that offset the o-ring off the flat plunger disc surface when the plunger is not actuated. When the plunger is actuated, the o-ring distorts to rest on the projections and also on the surface of the flat plunger disc. When the plunger is released, the o-ring's resiliency pulls the o-ring back to its original shape which sucks back the fluid being dispensed so that no or less drips occur.

Viscous material extruding dispenser

A mixing and discharge device is provided, in which contents are ejected from a pair of containers ( ) standing next to each other and are mixed and discharged outside of this device, by pressing down the discharge nozzles ( ) of said containers simultaneously with the manipulation of the thumb and a finger of the hand holding the containers. Said mixing and discharge device comprises an attachment ( ) to be fitted firmly around the top portion of the pair of said containers ( ), with respective discharge nozzles ( ) of the containers coming out of this attachment ( ); and a cap unit ( ) to be fitted detachably to the discharge nozzles ( ) and provided with a passage block ( ), which comprises a pair of step holes ( ) disposed in the areas near both sides, and into which the discharge nozzles ( ) are fitted tightly from underside, a discharge cylinder ( ) disposed at the center and on top of this cap unit ( ) to form a discharge port, and discharge passages ( ) for connecting this discharge port with the step holes ( ), wherein an actuating mechanism, with which to act a force to pull down the cap unit ( ) by the depressive operation of the manipulating plates ( ) in the lateral direction, is formed between a pair of manipulating plates ( ) hanging down from either one of the attachment ( ) or the cap unit ( ) and the portions facing these manipulating plates ( ) disposed on the other one of the attachment ( ) or the cap unit ( ). In this configuration, the portions with which to depress the discharge nozzles could have been displaced downward simply and stably. It has also been made possible to wash away the contents remaining in the discharge passage components.
