Abstract: A dropper assembly includes a dropper mechanism that includes a locking connector, an adjusting cap, and a press button. The locking connector has at least one dosage guide unit with a plurality of dosage guide grooves having different depths. The press button has at least one alignment rib portion insertable into one of the dosage guide grooves. The press button is driven by the adjusting cap to rotate between a locked position, where the alignment rib portion abuts against a top end of the locking connector and is thereby limited from being pressed downward, and a pressable position, where the alignment rib portion is aligned with one of the dosage guide grooves to enable pressing movement of the press button.

Abstract: A process for making a plastic container includes (a) grinding first pellets made from a polyolefin-based material to obtain fine powders, (b) preparing a blend for injection molding, the blend including a major amount of second pellets made from polyethylene terephthalate and a minor amount of the fine powders, (c) causing the blend to proceed through a heating zone so as to heat the blend, (d) injecting the heated blend into an injection mold to obtain a preform, and (e) subjecting the preform to blow molding. The fine powders have an average particle size not greater than 500 ?m.

Abstract: A container includes a container body for receiving a liquid, a locking connector, a pump unit and a depressible head assembly. The locking connector includes a locking ring threadedly disposed on a top portion of the container body, a dosage guide ring protruding upwardly from the locking ring, and at least one dosage guide unit. The pump unit extends downwardly into the container body and is drivenable to move in a top-bottom direction so as to draw the liquid in the container body. The depressible head assembly includes a depressible head for driving the pump unit to move in the top-bottom direction, and a biasing member abutting against the depressible head and the locking connector.

Abstract: A fluid dispenser device has a container filled with two concentric squeezeable tubes that has two concentric threaded outlets. The two threaded outlets are secured to an internal cap that has fluid passages for both outlets and external threaded sections for engaging the inner shell and an outer shell. The internal cap also has two barrier members on its outer walls that engage with the inner shell's sliders that releasably engage the inner shell in its open or closed positions. The inner shell threadingly engages a conduit unit that when lowered closes the fluid passages with projecting stubs and when raised opens those passages to allow dispensation from the container. The external cap has internal splines that engages the internal cap's external grooves. When the external cap is removed, the internal cap is rotated which in turn rotates and raises the conduit unit which opens the valves.

Abstract: A fluid dispenser device includes an internal cap adapted to cover top open ends of concentric inner and outer containers, and having first and second internal ports fluidly communicated with the top open ends, a conduit unit including a first conduit fluidly communicated with the first internal port through a first valve seat, a second conduit fluidly communicated with the second internal port through a second valve seat, and first and second valves respectively engageable with the first and second valve seats when the conduit unit is axially displaced, an inner shell engaged with the internal cap and the conduit unit, and a spline mechanism such that, when the inner shell is threadedly moved relative to the conduit unit, the conduit unit is displaced only axially to cause the valves to respectively disengage from the valve seats so as to permit dispensing of fluids contained in the containers.

With the displacement of the conduit unit, the first and second valves are movable to respectively disengage from the valve seats to permit dispensing of fluids contained in the containers.

Abstract: A liquid dispenser includes: a deformable container confining a fluid-storing space and having an open end defining an opening; an outer sleeve secured to the open end, extending into the fluid-storing space, and having an inner wall formed with a recess; an inner sleeve extending into the outer sleeve, defining an inner space, rotatable about an axis relative to the outer sleeve between first and second angular positions, and formed with a through-hole in fluid communication with the recess when the inner sleeve is disposed at the first angular position and not in fluid communication with the recess when the inner sleeve is disposed at the second angular position; and a brush-mounting seat extending into the inner sleeve.

Abstract: A brush applicator is adapted to be mounted to a liquid container and includes a brush unit, a hollow holding member, and a liquid discharging member. The brush unit includes a bristle-mounting seat and a plurality of bristles mounted on the bristle-mounting seat. The liquid discharging member is in the form of a single piece, and includes a base portion adapted to be received in the liquid container, and a tubular portion extending from the base portion through the bristle-mounting seat into the bristles. The liquid discharging member defines a fluid path extending through the base portion and the tubular portion. The hollow holding member is sleeved fittingly on the bristle-mounting seat and the base portion, and has a constricted open end for extension of the bristles therethrough.

Abstract: An applicator includes a tubular container, and a soft applicator tip bonded to the tubular container and having a composition including 60˜85% by weight of thermoplastic elastomer, 10˜30% by weight of polyolefin, and 5˜10% by weight of an adhesive. The adhesive is a modified polyolefin adhesive resin.

Abstract: A liquid dispenser includes a deformable container, a sealing unit and a brush unit. The container defines a liquid-storing space therein, and has a liquid-discharging opening for discharging a liquid contained in the liquid-storing space. The sealing unit is mounted movably on the container, defines a fluid channel, and is formed with a sealing member. The sealing unit is movable relative to the container between a closed position, in which the sealing member covers the liquid-discharging opening, and an opened position, in which the sealing member is spaced apart from the liquid-discharging opening. The brush unit is mounted on the sealing unit, includes a brush member, and defines a fluid passage in fluid communication with the liquid-discharging opening through the fluid channel when the sealing unit is disposed at the opened position.
