<p>A large-volume bottle such as a 1.5 litre bottle for carbonated non-alcoholic beverages is provided with a protective, non-adhesive coating of a very thin, stretchable polymeric material having medium-to-high cling to reduce the danger of excessive scattering of glass particles on accidental breakage of the bottle. The film is applied in helical convolutes extending from the bottom nearly to the top of the bottle and designed such that the pitch of each convolute is generally equal to the height of the covered portion of the bottle and, preferably, is not less than one-half of the height. The covering is easily strippable prior to the washing of bottles returned to the bottler. The bottles are then washed and recoated. The coating can be applied before or after the filling of the bottle and can even be applied by distributors or retailers prior to the placement thereof onto the shelves.</p> |
