Abstract
A quantitative pressing structure is disclosed herein. It comprises a pressing structure; an assembling seat disposed on the pressing structure for assembling at an opening of a container; a piston tube disposed at a bottom of the assembling seat and comprising a piston having a piston rod accommodated therein; a lid disposed at a top of the piston tube and having an outer casing protruded thereon and correspondingly disposed on a periphery of the piston rod, wherein an upper end of the piston rod of the piston penetrates the lid; a pressing portion disposed at a top of the piston rod; and a plurality of limiting kits having different heights for limiting a pressing down degree of the pressing portion, wherein each of the plurality of limiting kits has a slot for assembling on the outer casing of the lid.
Claims8
A quantitative pressing structure, comprising:
- a pressing structure;
- an assembling seat disposed on the pressing structure for assembling at an opening of a container;
- a piston tube disposed at a bottom of the assembling seat and including a piston having a piston rod accommodated therein;
- a lid disposed at a top of the piston tube and having an outer casing protruding therefrom and correspondingly disposed about a periphery of the piston rod, wherein the piston rod of the piston penetrates the lid;
- a pressing portion removably coupled to a top of the piston rod;
- and
- a plurality of alternatively selectable limiting kits having different heights for limiting a pressing down degree of the pressing portion, different ones of the limiting kits being selectively placed and replaced about the piston rod upon removal of the pressing portion from the piston rod, wherein each of the plurality of limiting kits includes a bottom portion forming a concave slot configured to receive the outer casing of the lid in conformed manner, a selected one of the limiting kits thereby adjustably limiting a pressing down degree of the pressing portion.
