A pump engine assembly includes an output cylinder that may be customized to include a stop portion limiting the stroke of a piston to produce a particular output such that customized pump systems may be produced from similar parts with the exchange of only a single partthe output cylinder.

The present invention relates to a variable metered amount airless applicator with cartridge. Examples of such an applicator include, for example, syringes and gun-shaped applicators. A variable amount selector is a feature of an embodiment of the applicator. The applicator can be attached to a variety of pass-through devices.

A quantitative dispensing device includes amounting seat, an elastic cap, a dispensing element, a regulating member, a rotatable seat and a press button that has a positioning unit. The regulating member includes a regulating unit that has a stepped-shaped top surface having a plurality of contacting surface portions. The press button is movable between a raised position, where the positioning unit is spaced apart from a selected one of the contacting surface portions, and a pressed position, where the positioning unit abuts against the selected one of the contacting surface portions and the press button is pressed downwardly against the elastic cap.

Provided is a cream-type cosmetic container having a vacuum pump which is configured such that a pumping member performs a pumping operation to discharge contents when a handle part is rotated by a predetermined section. Thus, contents having high viscosity can be discharged even with a small force. Furthermore, the container is configured such that a discharged amount of contents is adjusted according to a rotation angle of the handle part. Therefore, a user can use the container while adjusting discharged amount to a desired amount.

A perfume bottle including a head with an atomising nozzle oriented upwards at a specific angle with respect to the longitudinal axis of the bottle and a regulating mechanism by means of which it can deliver sprays at partial percentages. It can have a manual application or form a system with the bottle located at a base to have an electromechanical application from the base, both of the individual bottle and of a set of bottles located at the same base in a circular configuration, so as to obtain a specific mixture of perfumes applied to a user or in a refill bottle.
