  • Patent number: 5176291
    Abstract: A dispensing package (14, 114, 214) which is made up of a reusable pumping head portion (16, 116, 216) and a body portion (18, 118, 218) to which the head portion is removably attached. The pumping action is initiated by the reciprocation of an annular, reciprocable dosing piston (30, 130, 230) which may be a part of the body portion (30, 130) or a part of the head portion (230). The reciprocation of the dosing piston is initiated by the arcuate movement of a pumping lever (40) that is carried by the head portion. The pumping lever is biased by a spring (46) to return to its original position at the conclusion of a pumping cycle. Striping can be accomplished by providing the dosing piston with a spout (32, 232') that extends downwardly therefrom, the spout having a circumferential series of spaced apart apertures (32d, 232d') extending therethrough above a lower bottom tip portion (32b, 232b') thereof.
