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.

Synthetic resin bottle with handle and its production method

Herein disclosed is a liquid injection container which comprises: a container body 1; a cylinder 10 depending into the container body from a cap-shaped member 3 fitted on the outer face of the mouth/neck portion of the container body; and an actuator 20 having a stem 17 erected through the top wail 4 of the cap-shaped member from a cylindrical piston 16, which is fitted in the cylinder, and a head 18 fitted on the upper end of the stem and having a nozzle opened forward. The actuator is moved up and down with respect to the cylinder for sucking a liquid in the container body into the cylinder and discharging the liquid in the cylinder out of the nozzle 19 through the stem. A finger knob 80 attached to the top face of the head for receiving a finger. The vertical movements of the actuator are accomplished by the tip of the finger inserted into the finger knob. The actuations of the actuator are facilitated through use of auxiliary walls 6 and 6 acting as a finger knob and guiding the head. These auxiliary wails are erected along the righthand and lefthand two side portions of the head.

A cap structure having an elastic turnover cover. Body 1 of the cap structure is closed at the top of its first circumferential wall 2 with a cover 5 having a second circumferential wall 7 depending from the outer circumference of its top wall 6 by placing the lower end of the second circumferential wall 7 on the upper end of the first circumferential wall 2. The first and second circumferential walls 2 and 7 have their individual backs connected at their upper and lower ends by a hinge 10. The upper and lower portions of the backs of the first and second circumferential walls 2,7 are so connected through an elastic band 12 that the cover 5 can be opened or closed by the hinge 10. The hinge 10 is integrally molded of a synthetic resin at the back of the elastic band 16. This eliminates notches as a mold parting mark, which might otherwise be left in the cover when the cap structure of this kind is to be integrally molded of a synthetic resin in accordance with the prior art.

An aerosol-type liquid sprayer is adapted to spray liquid steadily without loosening. An erecting wall having an upper end portion engaged with an upper portion of a cylinder is connected to the outer surface of a container body neck portion. An erecting guide trunk is connected to the lower end of the erecting wall, and surrounds the erecting wall at a constant distance. A sliding trunk moves a piston upwardly and downwardly and is fitted into a gap between the erecting wall and the guide trunk. The sliding trunk is guided by the guide trunk, allowing the sliding trunk to be stably moved upwardly and downwardly.

A piston-cylinder liquid sprayer of long spraying time and simple construction has a long piston stroke and is adapted to spray liquid steadily without loosening. An erecting wall having an upper end portion engaged with an upper portion of a cylinder is attached to the outer surface of a container body neck portion. An erecting guide trunk is connected to the lower end of the erecting wall, and surrounds the erecting wall at a constant distance. A sliding trunk moves a piston upwardly and downwardly and is fitted into a gap between the erecting wall and the guide trunk. The sliding trunk is guided by the guide trunk, allowing the sliding trunk to be stably moved upwardly and downwardly, even if a longer stem is used.

A cap closing member for a container opening includes a main body and a lid having the same cross-sectional shape, rear surfaces of the main body and lid being connected to each other by two resilient belt plates. Each of the resilient belt plates forms a trapezoid with top sides that are oppositely faced to each other and connected to the rear surface of the lid. Each of the resilient belt plates is connected to the rear surface of the main body and a rear surface of the lid, so that the resilient belt plates do not project rearwardly from the circular cross-section of the lid or the circular cross-section of the main body.

Cap closing member for container opening

This invention relates to an improved sprayer cap structure associated with a neck portion of a bottle-shaped container for providing a liquid spraying operation or a liquid streaming operation. The sprayer cap includes an inner plug integrally formed adjacently with first and second hollow cylindrical portions in a top-walled cylindrical section. The cylindrical section is perforated with a first hole communicating with the bottom of the container through a pipe, and is also formed with a first valve chamber provided with a blocking valve at the upper position thereof and with a check valve at the lower position thereof. The cylindrical section further is perforated with a second hole and a third hole spaced longitudinally, and formed with a second valve chamber under the second hole, the second valve chamber being provided with a blocking valve at the upper position thereof. A nozzle unit is formed with a spinner slot capable of communicating with the first and second holes of the inner plug. The nozzle unit is perforated with a first nozzle hole substantially at the center of the spinner slot of the inner cylindrical section, and further perforated with a second nozzle hole capable of communicating the third hole of the inner plug adjacent to the first nozzle hole. A cylindrical cover unit is associated immovably with the container body.
