Abstract
A one-piece molded syringe with tethered cap is disclosed. The syringe has a hollow body having two parts, a pleated part forming a substantial part of the hollow body and a forward portion connected to the pleated part having a reduced cross-sectional area for receiving the fingers of a user. The cap is tethered to the syringe for maintaining the accessibility of the cap. A projection or pair of projections, formed integrally with the forward portion of the syringe, have a frusto-conical shape to receive the cap thereon. The projection(s) extends laterally outward from the forward portion to also serve as an abutment to prevent the syringe from rolling along a surface.
Claims17
A one piece molded syringe comprising:
- a hollow body having a longitudinal axis and a closed rear wall, a pleated portion forming a substantial portion of said body and adjoining said closed rear wall, and a forward portion adjoining said pleated portion and having a reduced cross-sectional area providing a finger gripping area of the syringe;
- thumb engageable means formed integrally with the closed rear wall of said hollow body for facilitating handling of the syringe during use;
- a nozzle connected to and extending outwardly from the forward portion of said hollow body and communicating with the interior of the hollow body for discharging contents of the hollow body therethrough;
- fracturable closure means formed integrally with the outer end of said nozzle for closing the nozzle until initial use;
- a closure cap connected to said forward portion of said hollow body and adapted for closure of said nozzle when the nozzle is opened, and
- projecting means, dimensioned to receive said closure cap thereon when the syringe is in use, extending laterally outward from the forward portion of said hollow body and beyond the periphery thereof and along an axis intersecting the longitudinal axis of said hollow body to also serve as an abutment for prevent rolling of the syringe along a surface.

A one piece molded syringe comprising:
- a hollow body having a longitudinal axis and a closed rear wall, a pleated portion forming a substantial portion of said body and adjoining said closed rear wall, and a forward portion adjoining said pleated portion and having a reduced cross sectional area providing a finger gripping area of the syringe;
- thumb engageable means formed integrally with the closed rear wall of said hollow body for facilitating handling of said syringe during use;
- a nozzle connected to and extending outwardly from the forward portion of said hollow body and communicating with the interior of the hollow body for discharging contents of the hollow body therethrough;
- fracturable closure means formed integrally with the outer end of said nozzle for closing the nozzle until initial use;
- a closure cap connected to said forward portion of said hollow body and adapted for closure of said nozzle when said nozzle is opened, wherein said closure cap is formed integrally with said fracturable closure means and extends forwardly therefrom;
- and
- projecting means, dimensioned to receive said closure cap thereon when the syringe is in use, extending laterally outward from the forward portion of said hollow body and beyond the periphery thereof and along an axis intersecting the longitudinal axis of said hollow body to also serve as an abutment for preventing rolling of the syringe along a surface.

- fracturable closure means formed integrally with the outer end of said nozzle for closing the nozzle until initial use;
- a closure cap dimensioned for closure of said nozzle when said nozzle is opened by fracturing of said fracturable closure means from said nozzle;
- elongate pliable tethering means, connected to said closure cap and said hollow body, for connecting said closure cap to said hollow body to prevent dislocation of the closure cap;
- and
- projecting means dimensioned to receive said closure cap thereon extending laterally outward from the forward portion of said hollow body and beyond the periphery thereof and along an axis intersecting the longitudinal axis of said hollow body to serve as an abutment for preventing rolling of the syringe along a surface when the syringe is not in use and for receiving said closure cap thereon when said syringe is in use.
