  • Patent number: 4572224
    Abstract: A unitary, integrally-formed, tubular receptacle serving as a storage receptacle from which fluid or fluid-like material is retrieved and applied by means of an insertable rod-like wand. The receptacle includes a container body of an elongated tubular configuration and integrally connected at its upper open end by means of an annular washer-like flange to a neck of substantially reduced diameter and defining a restricted internal passage having a radially inwardly directed annular wiping ring. The neck opens upwardly into a dish-like open-end throat having a curved lower sector defining a downwardly and inwardly directed wall surface serving as a guideway for entry of a wand downwardly through the restricted passage and also as a drain for facilitating return of excess wand-carried fluid material to the storage reservoir of the receptacle.
