Stretch blow molding begins with the production of a preform, either by injection molding or extrusion blow molding (or rarely, extrusion alone). The container finish is formed in this step. The preform is shorter than the final height of the container. Next, the body of the preform, on a stretch rod, is conditioned to an accurate, consistent temperature, usually just above its Tg, while the bottle finish is kept cool to avoid distortion. Then, the preform is placed in the container mold and is stretched by a vertical movement of the stretch rod while air is blown through the rod to expand the bottle into its final shape, stretching it axially (Fig. 12.13). 

The beer is filtered into pressure tanks and transferred to the bottling or keging machine. It is then pasteurized to avoid biological spoilage. The finished product is completed in five to six weeks for pilsner beer and six to nine weeks for the stronger beers. 

Many articles, bottles and containers in particular, are made by blow moulding techniques of which there are many variations. In one typical process a hollow tube is extruded vertically downwards on to a spigot. Two mould halves close on to the extrudate (known in this context as the parison ) and air is blown through the spigot to inflate the parison so that it takes up the shape of the mould. As in injection moulding, polymers of low, intermediate and high density each find use according to the flexibility required of the finished product. 

All bottle weights are finish weights (flash being considered 100 percent reusable). 

When I lift my gimlet for that first taste, and admire its color—a pale crystal green, like a legendary jewel—I m reminded of Lewis Carroll s Alice and her healthy sense of adventure. When confronted with a bottle with a label that instructed her to down it, she did Alice ventured to taste it, and finding it very nice (it had, in fact, a sort of mixed flavour of cherry-tart, custard, pine-apple, roast turkey, toffee, and hot buttered toast), she very soon finished it off. ... 

A manufacturer usually stores samples of both raw materials and finished products for extended periods of time. He may even be required to do so by law. Sample storage may present hazards often overlooked. A single bottle of perfume, for instance, is too small to be considered a fire hazard, even though the material is quite flammable. Hundreds of these bottles, however, stored away as retain samples by a cosmetics manufacturer will become a fire hazard. 

The juice is recovered by inserting tubular knives into the fruit and squeezing the fruit. Alternatively, the fruit may be cut in half and squeezed. The recovered juice is put through a finisher to remove a portion of the pulp sacs, is heated to inactivate enzymes, and is either bottled as single-strength juice or concentrated for frozen concentrate. 

He finishes pouring and the cap jingles as he puts it back on the bottle. Oh, that. Just caught my arm on the iron. ... 

Uses The urea formaldehyde resins are used for domestic electrical fittings, bottle caps. These also find use for wood adhesives, surface coatings and textile finishings. 

On account of the low boiling point care must be taken during the experiment that the preparation is never left for any length of time in an open vessel. Moreover, the finished preparation which is to be used for further work (cf. ethylbenzene) should not be kept in a thin-walled flask, least of all in summer, but should be stored in a thick-walled reagent bottle. Yield, 70-80 g. 

An experiment to determine the molecular mass of a gas begins by heating a solid to produce a gaseous product. The gas passes through a tube and displaces water in an inverted, water-filled bottle. The mass of the solid is measured, as is the volume and the temperature of the displaced water. Once the barometric pressure has been recorded, what other information is needed to finish the experiment ... 

When the chromatograms are finished, remove them from the bottle. Mark the highest point reached by the solvent. Then, allow the papers to air dry. 

In-mould labelling (IML) used for injection-moulded products and blow-moulded bottles is an alternative to self-adhesive or heat-transfer decoration, eliminating a finishing step. 

Extrusion is a continuous conversion process via melting and subsequent transformation of granules or powders of biodegradable polymers and additives into semifinished or finished articles like sheets, profiles, tubes, bottles, films, tapes or... 

A Polish man and his friend who is of Japanese descent are sharing conversation over drinks at a party. After the Polish man finishes his second bottle of beer, he notices that his friend, despite having drunk only half his drink, appears flushed in the face. His friend then complains of dizziness and headache and asks to be driven home. 

Ester polymers of methacrylic and acrylic acid are important in a wide range of applications. They are used in dental materials, glazing, adhesives, plastic bottles, elastomers, floor polishes, paint bases, plastic films, and leather finishes, to mention only a few. 

A typical feed composition was 1000 g capsul, 2334 g deionized water and 200 g orange oil. The finished powders were stored in amber bottles at -25prior to accelerated storage study and relevant analyses. Particle Size Analysis. To ascertain the effect of atomizer voltage on the particle size, the particle size distributions of three powders were first determined. The Microtrac laser light particle size analyzer (Medallion Laboratories, Minneapolis, MN) was used in this study. The volume percent data over particle diameter ranging 2.8 p. to 176 jii was recorded. Mean value of the volume percent distribution and calculated surface area were also obtained.
