Means and method for forming syringe

Claim 2

A means for forming a syringe, comprising: a first forming means being arranged to heat the bottom portion of a mono-molded plastic syringe, stretch said bottom portion to a certain length, form a needle and cut it in a certain length; and a second forming means being arranged to heat said needle of said syringe conveyed from said first forming means, bend said needle at a certain angle and cut it in a certain length.

Claim 3

The means for forming a syringe as claimed in claim 1, wherein said first forming means, further comprises: a first table, said first table being shaped like a disk and arranged to revolve intermittently conveying said syringe to a first carry-in section, a first heating section, a stretching section, a positioning section, a first cutting section and a first carry-out section, which are positioned in order; a plural number of first holders being positioned around the edge portion of said first table at regular intervals, holding said syringe in an upright standing position; a first heater being positioned in said first heating section and arranged to heat said needle of said syringe; a first revolver being arranged to revolve said first holders in said first heating section; a stretcher being positioned in said stretching section and arranged to stretch the bottom portion of said syringe to form said needle; a positioner being positioned in said positioning section and arranged to position said syringe in a certain direction; and a first cutter being positioned in said first cutting section and arranged to cut said needle in a certain length.

Claim 4

The means for forming a syringe as claimed in claim 1, wherein said second forming means, further comprises: a second table, said second table being shaped like a disk and arranged to revolve intermittently conveying said syringe to a second carry-in section, a second heating section, a bending section, a second cutting section, a reading section and a second carry-out section, which are positioned in order; a plural number of second holders being positioned around the edge portion of said second table at regular intervals and arranged to hold said syringe in a lying position with its needle facing in an outward direction; a second heater being positioned in said heating section and arranged to heat said needle; a bending means being positioned in said bending section and arranged to bend said needle at a certain angle; a second cutter being positioned in said second cutting section and arranged to cut said needle of said syringe in a certain length; an angle reader being positioned in said reading section and arranged to read an angle of said needle of said syringe; and an outside diameter reader being positioned in said reading section and arranged to measure an outside diameter of said needle of said syringe.

Claim 5

Method for forming a syringe, comprising the steps of: a first heating step, wherein a bottom portion of a syringe is heated and softened; a stretching step, wherein said bottom portion of said syringe is stretched a certain amount along a longitudinal axis of said syringe, said bottom portion being formed as a needle portion of said syringe and said needle portion being cut to a certain length; a second heating step, wherein the base portion of said needle portion is heated and softened; a bending step, wherein said softened needle portion is bent at a certain angle; a cutting step, wherein said bent needle portion is cut to a certain length; and a reading step, wherein an angle reader and an outside diameter reader are arranged to read an angle and an outside diameter of said needle portion of said syringe, respectively.

Claim 6

Method for forming a syringe, comprising the steps of: a first heating step, wherein a bottom portion of a syringe is heated and softened; a stretching step, wherein said bottom portion of said syringe is stretched a certain amount along a longitudinal axis of said syringe, said bottom portion being formed as a needle portion of said syringe and said needle portion being cut to a certain length; a second heating step, wherein the base portion of said needle portion is heated and softened; a bending step, wherein said softened needle portion is bent at a certain angle; a cutting step, wherein said bent needle portion is cut to a certain length; and a reading step, wherein an angle reader and an outside diameter reader are arranged to read an angle and an outside diameter of said needle portion of said syringe, respectively.
