A packaged ocular irrigating solution bag, which comprises a gas-permeable plastic multiple compartment bag and a gas-impermeable plastic packaging member for packaging the bag and in which an oxiglutatione-containing solution or solid preparation is enclosed in one compartment and a bicarbonate ion solution is enclosed in another compartment and the space between the bag and the packaging member has a carbon dioxide gas atmosphere.

A method or process for substituting an inert gas or blend of inert gases for ambient air in the head space of a container filled with leftover oil-based finish prior to sealing the lid. Even a tightly sealed container of leftover paint, stain, varnish, or other oil-based finish, will thicken, gel, or skin over with time. This occurs because the oxygen that is sealed in the storage container continues to react with oil-based finishes. The process involves using an aerosol can filled with the ine...

A heater for top portions of containers 11 filled with contents and each having a top forming tubular portion 14 generally rectangular to square in cross section for heating seal parts 31, 35 of the top forming portion 14 with hot air for heat-sealing comprises a hot air nozzle 51 in the form of a bottomed tube having a generally rectangular to square cross section and to be inserted into the top forming portion 14 for heating. The hot air nozzle 51 having first to fourth four side walls 61 to 6...

The process relates to the fitting of a bottom of a package formed from a tubular body (1) of non-round section. The open end of the body (1) is inserted between two fixed opposed jaws (M1, M2). Since the distance between the jaws (M1, M2) is less than the distance between the clamped portions (2, 3), the portions (4, 5) which are not clamped deform. Thus, when fitting the bottom, the air escapes and by applying a clamping force to the side walls of the package (1), some of the air still in the ...

An apparatus for extracting air from within flexible packages having granular or otherwise flowable contents includes a package conveyor and a downwardly-open, vacuum extraction hood through which the packages are conveyed so that an upper portion of each package is moved through the extraction hood. The interior of the hood is joined in fluid communication with a vacuum source, so that air is extracted from within each package as it is conveyed through the hood. The present apparatus further in...

A head space inserting system is used in a packaging machine for forming, filling and sealing packages. The inerting system directly introduces an inerting gas into the head space of the formed package subsequent to filling and prior to sealing. The inerting system includes an inerting gas source, an inerting gas heater to heat the inerting gas and an inerting gas nozzle. The inerting gas nozzle is disposed within the form, fill and seal packaging machine to introduce the inerting gas directly i...

A heat-shrinkable multilayer film comprises (A) a first layer, which is an outer layer, and which comprises polyolefin; (B) a second layer comprising at least one member selected from the group consisting of polyolefin, polystyrene, and polyurethane; (C) a third layer comprising at least one member selected from the group consisting of amorphous polyester and polyester having a melting point of from about 130.degree. C. to about 260.degree. C.; (D) a fourth layer, which is an outer layer, the fo...

A candling method for detecting anomalies in translucent material (10) e.g. parasites in fish fillets, comprises directing an illumination beam (Io) of light through the material. It has been discovered that improved results in terms of more reliable detection of anomalies, and the ability to locate such anomalies in thicker samples than has previously been possible, can be obtained by using a beam with a radius no greater than 1 mm and preferably no greater than 0.5 mm. For still better results...

An overload relief system is provided for a press bolster comprising a ram portion and a cylinder portion. The cylinder portion defines a cavity adapted to receive the ram portion, and the cylinder and ram portions together define a pressure chamber. The pressure chamber is sealed and pressurized, and the relief system functions to relieve the pressure in the chamber in the event of a press overload condition.

Device (10) for achieving communication, via a coupling means, between a first chamber (1) and a second chamber (2). The coupling means comprises, on the same side as the first chamber (1), a first shut-off member (41), and, on the same side as the second chamber (2), a second shut-off member (4) comprising a second flange (52) forming a seat for a second removable shutter element (72). The coupling means further comprises means of sealed connection between two flanges (51) and (52). The second ...
