Abstract
Abstract A toy water pistol having a detachably securable watercontaining cartridge which serves not only as a reservoir for a substantial amount of water, but also as a biasing means for the trigger. The cartridge is constituted as a multiply-pleated bellows which is retained in a simulated barrel portion of the pistol. This portion is open on one side, permitting the cartridge to be easily inserted and removed. The forward end of the bellows has an orifice through which water is ejected when the bellows is compressed by squeezing of the trigger. A plunger having longitudinally spaced transverse webs is guided by axially extending, circumferentially spaced ribs within the barrel.
