Abstract: A drip emitter system and head is disclosed, the system including a line through which water may pass, the line having a series of spaced openings. Drip emitter heads are received in these spaced openings, each head including a bulbous end received within the line, the end being larger than the opening, and a flared top external to the line. A shank connects the bulbous end and flared top of the head, at least a portion of the surface of the shank being tapered and narrowing from the bulbous end gradually towards the top, whereby increased pressure in the line increases the forces on the head, forcing the shank more firmly into the opening in the line and causing it to constrict water flow between the shank and the opening. The surface of the shank may be substantially circular in cross section, or may include one or more longitudinal grooves for water. The undersurface of the head may be oriented generally parallel to the surface of the line so that emitted water will strike it and spray outwardly.

Abstract: A composite structure is shown wherein a fibrous body or a tube such as a convolute or spirally wound paper tube or mold pulp bucket supports a plastic liner within the body to form a container. The material forming the mouth of the plastic liner is overlapped around at least one end of the supporting body and the outer overlapped layer of plastic is shrunk onto and around the outer side at the end of the support. In one form of the invention, the liner may be sealed at one end to form a bag suspended within the container to hold the product and caps may be applied to the open end or in the case of a tubular body, caps can be applied to the opposite ends of the body to complete the package.

Abstract: A carrier is disclosed for interconnecting an array of cans or the like to hold them together as a unitary package. Preferably the carrier is made from a sheet of a material such as polyvinyl chloride that may be cut, expanded and set in its expanded state, then later after being placed around an array of cans, shrunk to interconnect the cans and form a package. Because of the design of the carrier and its method of application to an array of cans, a cover film may be attached by the carrier over the array of cans to keep the can tops clean. Machines and methods are disclosed for forming, transporting and applying in a rapid and economic manner, a web of such carriers to a series of cans or the like.

Abstract: A simple, two-part adjustable spray device is disclosed, the device consisting of a tubular member within which is a cylindrical insert member. At its inner end, the insert member includes a chamber in selective communication with both the inlet portion of the tubular member and a longitudinal channel formed in the internal wall of the outlet portion of the tubular member. The side wall of the insert member defining the chamber is sufficiently flexible to be distended by the pressure of liquid within the chamber into a sealing engagement with the interior side wall of the tubular member. By rotationally adjusting the insert member, the chamber may be brought into selective communication with the longitudinal channel to allow a varying volume of liquid to pass from the inlet to the outlet and a spray of liquid to be emitted through a profiled aperture.

Abstract: A carrier is disclosed for interconnecting and holding an array of cans or the like together as a unitary package. Preferably the carrier is made from a thermally shrinkable plastic sheet, and is formed to be placed around an array of cans then shrunk by application of heat to interconnect the cans and form the package. A machine is disclosed for performing this packaging operation efficiently and rapidly, the method including the step of preforming the plastic sheets to provide a cylindrical collar about each opening, thereby enhancing the hold and interconnection afforded by the carrier. A cover sheet may be employed with the carrier to keep the can tops clean. The method for performing this packaging operation also is disclosed.
