First claim
Opening claim text (preview).
The invention claimed is: 1. A heating apparatus for preforms that heats a preform to a temperature for blow-molding the preform into a bottle, the heating apparatus comprising: a mouth portion heating section that heats a mouth portion of the preform; and a body portion heating section that heats a body portion of the preform, wherein the mouth portion heating section includes mouth portion heating equipment that heats the mouth portion to a temperature in a range of 50° C. to 70° C., wherein an early stage in the heating apparatus for preforms comprises the mouth portion heating section and the body portion heating section, and a final stage in the heating apparatus comprises the body portion heating section and a cold air blowing nozzle, and wherein the cold air blowing nozzle has a flat shape facing the mouth portion of the preform. 2. The heating apparatus for preforms according to claim 1 , wherein the body portion heating section includes body portion heating equipment that heats the body portion to a temperature in a range of 90° C. to 140° C. 3. The heating apparatus for preforms according to claim 1 , wherein the mouth portion heating equipment includes a halogen lamp and a condenser that collects near infrared radiation emitted from the halogen lamp to the mouth portion. 4. A heating method for preforms comprising: providing a preform to which a disinfectant containing hydrogen peroxide has been blown; and heating the preform to a temperature for blow-molding the preform into a bottle, wherein a mouth portion of the preform is heated to a temperature in a range of 50° C. to 70° C., wherein the mouth portion and a body portion of the preform are heated in an early stage of heating the preform, wherein the body portion is heated and the mouth portion of the preform is blown with cold air in a final stage of heating the preform, and wherein the cold air is blown from a cold air blowing nozzle having a flat shape facing the mouth portion of the preform. 5. The heating method for preforms according to claim 4 , wherein a body portion of the preform is heated to a temperature in a range of 90° C. to 140° C. 6. The heating method for preforms according to claim 4 , wherein the heating of the mouth portion is achieved by collecting near infrared radiation emitted from a halogen lamp to the mouth portion of the preform. 7. The heating apparatus for preforms according to claim 2 , wherein the mouth portion heating equipment includes a halogen lamp and a condenser that collects near infrared radiation emitted from the halogen lamp to the mouth portion. 8. The heating method for preforms according to claim 5 , wherein the heating of the mouth portion is achieved by collecting near infrared radiation emitted from a halogen lamp to the mouth portion of the preform.
