A pressure sprayer includes an accumulator vessel adapted to hold a pressurized fluid therein and a container that is configured to hold a chemical concentrate. A motor in fluid communication with the accumulator vessel and the container is adapted to be driven by the pressurized fluid and to pump the pressurized fluid and the chemical concentrate. A chamber is adapted to receive the chemical concentrate and the pressurized fluid from the motor to form a chemical solution. A nozzle is in fluid communication with the chamber.

The bottle closure comprises a generally cylindrical inner member adapted to be threadedly engaged on the outside of the neck of a bottle. The inner member has a central passage communicating with the neck of the bottle. An outer member is rotatably mounted on and around the inner member. The inner member includes a valve seat defining a fluid passage between the bottle and the outer member and being located within the neck of the bottle. The outer member includes a valve closure element adapted to close the fluid passage in a first annular position of the outer member on the inner member thereby to form a seal with the valve seat. The outer member, when moved to a second annular position relative to the inner member, opens the fluid passage, thereby to allow fluid in a bottle to flow through the closure.

Bottle

A thermoplastic bottle has a generally cylindrical body, in turn having an upper portion, a lower portion, and opposite sides joining at a diametric plane. A plurality of adjacent finger recesses extend about one of the opposite sides in the lower portion of the body, and a thumb depression is provided in the lower portion on the other of the opposite sides. A continuous circumferential indentation is formed in the cylindrical body between the upper portion and the lower portion to decouple pressure response of the upper and lower portions and minimize lean transfer to the upper portion resulting from expansion of the lower portion on the one of the opposite sides. The bottle is also formed with at least one vertical reinforcing indentation, preferably at least one set of three such vertical reinforcing indentations in each of the finger grooves, and at least one, preferably three spaced vertical reinforcing indentations in the thumb depression. The bottle has a bottom closure base having an odd number of at least five projecting feet, one of the feet being aligned vertically with the thumb depression so that at least three of the five feet remain in a common plane during vertical stretching to assure a stable base for maintaining the bottle in upright posture.

Pressured thermoplastic beverage containing bottle with finger gripping

The invention is a plunger useful in extruding or dispensing viscous material which comprises a thin disc of a material which is capable of deforming when subjected to back pressure during use. The edge of the disc has a circular shape and a cylindrical lip attached to the edge of the disc, which lip is disposed perpendicular to the edge of the disc. The disc has a face and a back surface located on opposite sides of the sheet. The disc also has a symmetrical convex portion which protrudes beyond the plane defined by the edge of the disc in the direction of the face and the peak of the convex portion disposed in the center of the disc. The disc further comprises a symmetrical concave portion which protrudes beyond the plane defined by the edge of the disc in the direction of the back surface. The concave portion of the disc surrounds the convex portion of the disc and the convex portion starts at the bottom of the concave portion. The radius of the convex portion, measured from the peak to the bottom of the concave portion, is sufficient to withstand the back pressure exerted during use without inverting. The slope of the wall of the concave portion from the edge to the bottom of the concave portion is disposed such that, when back pressure is exerted on the plunger, the edge deforms radially outward.
