A liquid jetting pump of the present invention is constructed such that an intra container liquid is sucked into a cylinderthrough a suction valveby moving a vertically movable memberup and down, and the intra cylinder liquid is jetted out of a nozzlethrough a discharge valvefrom a stem. A plurality of ribsare protruded in a peripheral direction from a lower edge part within the cylinder. Engagement recessed portionsare formed in inner parts of the upper surfaces of the ribs. A lower edge of a coil springfor biasing the vertically movable memberis secured to each of the engagement recessed portions, thereby permitting a flow of liquid on both sides of the lower edge of the spring internally externally.

A liquid jet pump constructed to suck a liquid within a container on which the pump is mounted and jet the liquid out of a nozzle by pushing down the head of the pump. The nozzle is so formed so as to ascend forward obliquely, and is provided with a discharge valve housing a ball-like valve for closing a valve seat provided at an proximal edge within the nozzle. The valve member is movable both back and forth within the nozzle to keep the liquid from dripping of the nozzle.

Liquid jet pump

Liquid jetting pump with passageways for dispensing liquids

A synthetic resin bottle produced by blow-molding a parison of a synthetic resin. In the blow-molding process of the parison, the portion of the parison supporting the handle is prevented from being expanded, thereby to sufficiently increase the supporting strength of the handle. Since the bottle product has its drum recessed in the vicinity of the handle, the grip of the handle can be facilitated.

Method of producing synthetic resin bottle with handle

A trigger-actuated atomizer pump has a first engagement member held in fitting engagement with a second engagement member on a flattened liquid container for orienting the atomizer pump securely against rotation relative to the flattened liquid container with an atomizer trigger directed in registration with the plane in which the container is flattened. The first engagement member may include a lateral projection extending remotely from the atomizer trigger so that an operator's hand can be held at the back of the thenar against the lateral projection to facilitate gripping the atomizer for fatigue-free operation in a long period of time.
