摘要:
At the step of preheating the container, in addition to heating of the whole container, a neck portion (1a) of the container may be heated separately. Alternatively on the step of preheating the container, while whole container is heated by a hot air blast which is supplied in the container, neck portion (1a) of the container may be heated separately. Since it is difficult to increase the temperature of the neck portion as compared with other portions, by heating the neck portion separately, the effect of the preheating is performed more effectively. It is desirable that the hot air blast is supplied from the nozzle inserted in the container. For example by the method of spraying hot air blast from the outside of the portions, heating of the neck portions can be performed.
摘要:
A high speed sterilization method for sterilizing a container, such as a beverage bottle, and an apparatus for performing the method. The method is performed by first preheating the container. The neck portion of the container may be heated separately and additionally to the preheating of the container. A disinfectant mist is then supplied into the container. The container is then heated. Finally, the container is rinsed.

A fuel pump includes a case member defining a fuel passage and a discharge-side cover connected to the case member and defining an outlet port. A pump section has an inlet port and is connected to the case member. A motor section is housed in the case member for driving the pump section. A positive electrode terminal and a negative electrode terminal are supported by an insulative terminal support member fixed to the discharge-side cover. Base portions of the positive and negative electrode terminals are covered by insulative portions. The insulative portions are fitted in fitting holes of the discharge-side cover. The discharge-side cover has guide portions on its inner surface. The terminal support member has engagement projections on opposite side walls thereof. The engagement projections are guided by the guide portions to restrict the discharge-side cover from rotating with respect to the terminal support member.

A copolymer having a high molecular weight, excellent toughness, transparency and heat resistance, and additionally having a high melt tension can be obtained with a reaction time less than a half of the conventional process. The copolymer obtained by the invention is a material suited for injection molding, extrusion, calendaring, blow forming, balloon forming, vacuum forming and foaming. Particularly, the copolymer obtained by the invention has a high melt tension and thus the molten copolymer is difficult to sag and flow and can be processed with ease into foams and blow bottles.
