Abstract

A method of making a multiple neck spray bottle comprising the steps of providing a blow mold having a molding cavity configured for molding a multiple-neck spray bottle have multiple open headed neck portions with at least one threaded neck portion configured to connect with the spray head, providing at least one plastic parison inside the molding cavity, blow molding the at least one parison inside the molding cavity to form the multiple neck spray bottle, and opening the blow mold to release the formed multiple neck spray bottle from the blow mold.

Claims

1. A method of manufacturing a multiple neck spray bottle for use with a spray head, said method comprising the steps of:

providing a mold having a molding cavity configured for blow molding a multiple neck spray bottle having multiple externally threaded neck portions with at least one threaded neck portion configured to connect with the spray head;

providing at least one plastic parison inside the molding cavity, the neck portions of the multiple neck spray bottle being molded are located substantially within a width of the parison;

blow molding the parison provided inside the molding cavity with a single blow pin to form the multiple neck spray bottle with at least one neck portion of the spray bottle being formed in a wall portion of the spray bottle;

opening the blow mold to release the formed multiple neck spray bottle from the blow mold; and

opening the at least one neck portion formed in the wall portion of the spray bottle.

2. A method according to claim 1, wherein said at least one parison is extruded from hot plastic melt.

3. A method according to claim 2, wherein said at least one parison is extruded in a hollow cylindrical shape about said at least one blow pin, and wherein said parison is extruded between mold halves of the blow mold in an open mode.

4. A method according to claim 1, wherein said step of opening is provided by one selected from the group consisting of a tool located external to the blow mold, a tool located internal to the blow mold, air jet located external to the blow mold and air jet located internal to the blow mold.

5. A method according to claim 1, wherein separate neck portions of said multiple neck spray bottle are provided at different heights of the spray bottle.

6. A method according to claim 1, wherein a first neck portion of the multiple neck spray bottle is formed vertically, and a second neck portion is formed at an angle relative to a vertical axis of the spray bottle.

7. A method according to claim 6, wherein a wall of said second neck portion is formed so as to be reinforced against deformation compared with other wall portions of the spray bottle.

8. A method according to claim 1, wherein said blow mold is provided with a single through hole for accommodating said single blow pin.

9. A method according to claim 1, wherein said at least one parison is injection molded prior to the step of blow molding.

10. A method according to claim 9, wherein said step of opening is provided by one selected from the group consisting of a tool located external to the blow mold, a tool located internal to the blow mold, air jet located external to the blow mold and air jet located internal to the blow mold.

11. A method according to claim 1, wherein said plastic parison is made of plastic of one selected from the group consisting of polyethylene, polypropylene, polyvinyl chloride (PVC), and polyethylene terephalate (PET).
