    摘要： This relates to blow molded plastic containers wherein at least the body of such containers is of a laminated construction including, for example, a barrier layer which in the case of the container receiving carbonated products would be a gas barrier layer. It has been found that delamination does occur and this is now solved by selectively providing the container body with minute vent openings which do not extend entirely through the container body, but into that area where delamination occurs and there is an accumulation of a permeant, such as CO.sub.2. The minute vents may be formed in the exterior wall of the container either by way of piercing pins or by utilizing a laser. In the case of the piercing pins, there are incorporated in the blow mold for blow molding the container from a preform and are generally placed along the parting lines of the blow mold and also in central parts of the wall. The construction and operation of the piercing pins may be provided in several forms.

    摘要： An apparatus for forming multiple layer preforms wherein the various layers may be varied as to number, material, thickness and position in the preform by controlling the injection of the specific materials as to timing, quantity and rate of delivery. Most specifically, a featured aspect is the ability to simultaneously deliver to an injection nozzle and through such injection nozzle into a preform mold cavity two or more molten plastic materials simultaneously. This is possible by way of a multiple gate nozzle and a plurality of separately operable metering pots all controlled by way of a timing device. The timing device may also control the rate of the dispensing an individual material from each of the metering pots.

    摘要： An injection molded plastic preform for forming by blow molding a container such as a bottle. The preform is of a laminated construction and in the body area includes inner and outer layers of the same plastic and an intermediate layer of a different plastic. The bottom portion of the preform is provided with a core layer of still a third plastic with the injection temperature of the third layer being sufficient to erode the contacted part of the intermediate layer which is of a lower melt temperature. The third plastic may be the same plastic as the first plastic, but injected at a higher temperature. Generally speaking, the neck finish of the preform will be of a single layer of the first material, the body of the preform will be of a three ply construction which is also true of the bottom with there being an intermediate area of five ply where the bottom core layer projects into the lower portion of the intermediate layer.
