A pack for liquids is made at least partially from cardboard or the like, which is impervious to liquid at least on its one surface, by virtue of a plastics coating. The pack has side walls (1-3), a bottom and a top wall (1), which are connected together at least partially by fold (9) and/or sealing seams (4), a tear-open pouring opening (6) which is disposed in the top wall (1) adjacent the edge line (9) and which is preferably covered over by a tear-off cover strip (7) and a pouring edge (8) w...

Container (11) for liquids has a spout with an air bleed channel (10) for improving the ease of pouring the liquids. The container has a retractable nozzle, the outlet end of which has a double wall (3,4) defining an annular space. The annular space is open at both ends and communicates with the air bleed channel in both an extended and a retracted position of the nozzle. The air bleed channel communicates with the main body of the container via its hollow handle.

A flexible impervious gland is connected to a cylindrical body and both the gland and body are sandwiched between two halves of a sponge. A passage is formed within the body and a valve is mounted within the passage. An aperture communicates the passage with the gland and a second aperture communicates the passage with the outside wall of the body. The gland serves as a reservoir for liquid such as soapy water. In one embodiment, a manually rotatable cap or head is connected to the valve. Upon r...

A beverage dispensing system is disclosed which uses throw-away plastic packages in which beverage concentrate is contained. The package comprises a body and an integral valve. The valve has a sleeve in which is contained a rotary barrel. The barrel defines two sub-chambers. As the barrel is turned by a drive of the machine, the valve is positioned so that one of the sub-chambers dispenses its contents into a drinking vessel, while the other refills and vice versa. As long as concentrate is bein...

Two immiscible liquids are vaporized in heat exchanger tubes in a manner such that each tube receives both liquids and neither liquid is completely vaporized in the tubes.

There is provided a new and useful bottle for containing and pouring liquids comprising a body section having bottom, front, back and first and second sides, and a neck section, the first side including a lower section, and an upper elongated sloped shoulder section narrowing progressively to intersect the neck section at a first line of intersection, the second side including a lower section, and an upper sloped shoulder section narrowing progressively to intersect the neck section along a seco...

A flask, particularly for carrying alcoholic beverages, comprises a tubular body portion, having a seamless continuous internal surface, with respective inner end members fitted in the body portion to close the ends thereof and respective outer end members secured by soldering to the body portion at the ends thereof to define respective chambers between the inner and outer end members. The solder of the joints is out of contact with the interior of the flask, and any excess solder is received in...

Electrostatic spraying for pesticides comprises an electrically conducting or semi-conducting surface; means for supplying liquid adjacent the surface; and a field intensifying member in close proximity to the surface. A process for the ultra-low volume application of concentrated pesticidal formulations by means of the apparatus is also described.

In a blank for folding into a parallelepipedal package that is intended for liquids, the blank having an area that is to be folded into a double-M closure for a gable-shape top having inwardly folded opposite triangular sections and a middle fold line, the improvement which comprises providing each of said opposite triangular sections with a slit that slants from the upper edge down to or slightly beyond the middle fold line, whereby the folded package has an improved seal. When the cross-sectio...

Liquid additives can be supplied to a fermenter vessel from a reservoir by a dispensing device which comprises a central discharge chamber connected in series between an upper escape chamber and a lower inlet chamber. These chambers are arranged to provide a smooth passage for liquid and do not have any steps or recesses therein. An escape port leading from the upper end of the escape chamber to the reservoir is controlled by a valve member. An inlet port leads into the lower end of the inlet ch...
