Abstract
A dispensing container having a neck with a throat opening closed by a cap having a pierceable membrane adjacent atop of the cap, the cap having a dispensing nozzle with a lumen therethrough and an overcap for enclosing the dispensing nozzle having a moveable plunger pin extending into the lumen of the nozzle and moveable therein to pierce the membrane.
Claims11
A dispensing fluid hollow container and cap assembly comprising:
- a) a container body having a neck with an opening to the body's interior at one end of a neck, the neck having external threads;
- b) an intermediate cap having first and second ends, the intermediate cap having a hollow large diameter portion skirt at a first end of the intermediate cap having internal threads engageable with the body neck threads whereby the cap is screwed to and carried by said container body, the intermediate cap having a dispensing channel open to said opening and to a second end of the intermediate cap remote from the skirt end, the channel closed by a pierceable membrane intermediate the first and second ends, the intermediate cap having a smaller diameter axial portion extending from the larger diameter portion to the second end, the smaller diameter portion having external threads;
- c) a nozzle cap having an internally threaded skirt at a first end carried by said intermediate cap by threaded attachment to exterior threads of the smaller diameter portion of the intermediate cap, the nozzle cap extending from the second end of the intermediate cap and having a lumen therethrough open to the channel adjacent the first nozzle cap end, the lumen terminating in a dispensing tip opening at a second nozzle cap end remote from the first nozzle cap end;
- d) an overcap received over the nozzle cap and threadably connected to the exterior of the nozzle cap;
- e) a piercing pin member carried by the overcap and positioned in said lumen when the overcap is threaded onto the nozzle cap and moveable therein to pierce an opening through a central portion of said membrane leaving the membrane attached to the intermediate cap, said pin removable from said membrane and said lumen after piercing by removing the outercap whereby after piercing the membrane, contents of the container body can be dispensed through the pierced membrane opening, through the lumen and from said remote dispensing tip opening, said pin being reinsertable in said lumen and into the pierced opening in the membrane without further substantially enlarging the opening by reattaching the overcap to the intermediate cap.

A dispensing container and cap assembly comprising:
- a hollow container body having a neck with an exterior and a throat opening open to an interior of the body, an intermediate cap having internal threads threaded to an exterior of said neck and having proximal and distal ends with a dispensing channel open to each end, the proximal end opening to said throat, a pierceable membrane closing said dispensing channel intermediate the proximal and distal ends the intermediate cap having external threads at the distal end, a nozzle cap having an elongated tapered dispensing central portion extending from a skirt portion having internal threads engaging the external threads of the intermediate cap axially spaced from the cap's internal threads, the central portion having a lumen therethrough, the nozzle cap when threaded to the intermediate cap carried by said intermediate cap with said lumen open to said channel, the lumen terminating at a distal end of the nozzle cap in a dispensing tip opening, an overcap threaded to an exterior nozzle cap and movably carrying a piercing member, the piercing member insertable through said lumen and moveable therein independent of movement of the overcap to pierce said membrane when the caps are threaded together, the piercing member being removable from said lumen and from said membrane after piercing by removal of the overcap from the nozzle cap, the piercing member dimensioned to pierce only a central portion of the membrane with the remaining portion of, the membrane remaining attached to the intermediate cap after piercing.
