Title:
PUSH HEAD UNIT OF PUMP DISPENSER
Document Type and Number:
WIPO Patent Application WO/2014/142397
Kind Code:
A1
Abstract:
The present invention relates to a push head unit of a pump dispenser. The aim of the present invention is to be able to apply dispensed contents through a massage member directly onto the skin without using the palm of the hand, and to make attachment/detachment of the massage member easier during cleaning or replacing of same. To this end, the "push head unit of a pump dispenser" according to the present invention comprises: a head-body (310) coupled to the upper end of a piston shaft (240), and having a content discharge flow passage (311) formed on the inside thereof; a nozzle base (320) of which the centre on the rear surface has a coupling opening (321) coupled by insertion into the fore-end part of the discharge flow passage (311) of said head-body (310) while also linking through to same, and of which the front surface is provided with a first cylinder wall (323) forming a content-discharging space (322) while having a coupling protrusion (324) in the form of a belt on the outer circumferential surface thereof, and is provided with a second cylinder wall (326) constituted so as to form a gap in conjunction with said first cylinder wall while surround same and having a wave-shaped first concavo-convex hollow (325) on the outer circumferential surface thereof; a nozzle cover (330) in which a plurality of nozzle holes (331) are perforated in central positions in order to allow outward discharge of the contents that have been discharged from the content-discharging space (322) of said nozzle base (320), and which is detachably coupled while covering the front surface of said nozzle base (320), and of which the rear surface is provided with a first coupling wall (333) coupled so as to surround the outer perimeter of the first cylinder wall (323) of said nozzle base (320) and having on the inner circumferential surface thereof a coupling hollow (332) in the form of a belt that mates in concavo-convex fashion with said coupling protrusion (324), and is provided with a second coupling wall (335) coupled so as to surround the outer perimeter of the second cylinder wall (326) of said nozzle base (320) and having on the inner circumferential surface thereof a wave-shaped second concavo-convex hollow (334) adapted to mate with said first concavo-convex hollow (325); a massage member (340) (340A) which is disposed on a front part of said nozzle cover (330) and is configured to touch skin elastically while applying the contents that have been discharged through said nozzle holes (331); and an over cap (350) which is constituted in the shape of a cup so as to detachably cover the second coupling wall (335) of said nozzle cover (330) while wrappping around said massage member(340) (340A), and in which a latching shoulder (351) is constituted so as to project along the inner circumferential surface of the opening; and, in the present invention, a locking protrusion (337) is formed to the rear of the second coupling wall (335) of said nozzle cover (330) so as to latch onto the inside of said latching shoulder (351) of said over cap (350), and a pair of locking knobs (338L) (338R) are disposed at opposing positions thereon so as to be able to selectively undo the state of latching of said locking protrusion (337) when pressed toward the center part.
