1. An elastomeric dispensing container for a fluid comprising:

  • a flexible and resilient receptacle composed of an elastomeric material defining a chamber therein;

    opposite upper and lower ends of the receptacle with the receptacle having a central, longitudinal axis extending between the opposite ends thereof and a predetermined axial length of the receptacle between the opposite ends,an integral gasket of the receptacle extending radially from an opening formed at the receptacle lower end;

    a receptacle neck extending up from the receptacle lower end for providing communications between the chamber and the opening, wherein the integral gasket and the receptacle are fabricated as a single piece from the elastomeric material,a discrete sleeve composed of a substantially rigid material and having opposite upper and lower ends, with the sleeve being disposed concentrically about the receptacle neck having a sleeve neck with a lower face at the sleeve lower end and which is disposed adjacent to the integral gasket,a cap having a lid covering the receptacle opening and the integral gasket with a dispensing orifice formed therein and a cap neck extending from the lid disposed concentrically about the sleeve neck, the cap having open and closed positions,engaging means formed on the sleeve neck and the cap neck providing removable attachment therebetween wherein the engaging means secures the integral gasket in a compressed and substantially fluid-tight state between the lid and the sleeve lower face; and

    a wall portion of the receptacle that is configured to be resiliently deformable and which has a predetermined, non-deformed configuration, the wall portion extending about the chamber and upwardly from the sleeve upper end to the receptacle upper end so that the entirety of the receptacle exposed above the substantially rigid sleeve is available to be compressed to pressurize fluid in the chamber for expelling the fluid from the receptacle chamber through the cap orifice with the cap in the open position and to allow air to be drawn into the receptacle chamber as the wall portion resiliently returns to the predetermined, non-deformed configuration thereof.
