Abstract
A liquid discharging apparatus having a simple construction and capable of reducing the number of components with high efficiency is provided. The liquid discharging apparatus for discharging a liquid contained in a container from a nozzle head that is mounted on a cap attached to an opening of the container and is movable up and down together with a piston is characterized in comprising a virgin seal body positioned around a piston engagement hole formed on the cap and integrated with the cap so as to be separable from the cap by way of a thin portion, a vertical slit defined in the virgin seal body and having a pinch portion provided with a slip stopping portion at the opened portion thereof, wherein the nozzle head is fixed to its top dead center by the virgin seal body when the liquid discharging apparatus is not used.
Claims19
A liquid discharging apparatus for discharging a liquid comprising:
- a container for containing the liquid therein;
- a cap attached to an opening of the container;
- a nozzle head mounted on the cap;
- a piston integrated with the nozzle head at a lower portion thereof, said nozzle head being movable up and down together with said piston, said piston defining a valve seat and including a valve seal body provided on the valve seat;
- a virgin seal body integrated with the cap and positioned around a piston engagement hole formed in the cap, wherein the nozzle head is fixed to its top dead center by the virgin seal body when the liquid discharging apparatus is not in use;
- and
- a valve disposed inside a housing attached to the cap, said valve including an end portion which extends upwardly and is integral therewith, said end portion separating a portion of said valve seal body from said valve seat while another portion of the valve seal body remains connected to the valve seat when said nozzle head is pushed downwardly.
A liquid discharging apparatus comprising:
- a generally hollow container body for storing liquid therein;
- a closure arrangement mounted on an upper end of said container body and including a nozzle member mounting a piston thereon, said nozzle member and said piston being movable so as to allow discharge of liquid stored in said container body through an opening defined in said nozzle member, said piston defining a valve including a valve seat and a valve body attached to said valve seat;
- and
- a valve mounted within said container body and including an upper end portion disposed adjacent said piston valve, whereby said upper end portion partially separates said valve body from said valve seat upon downward movement of said nozzle member and said piston by a predetermined distance to allow liquid stored within said container body to exit through said opening.
