Syringe with needle

Abstract

A syringe and needle assembly including a needle tube having a needle tip for puncturing a living body. A syringe is formed integrally with the needle tube. The syringe includes a main body to be filled with a drug and a securing section that is formed integrally with the main body. The securing section has a close contact area that has an outer peripheral surface that contacts an inner surface of a cap when the cap is attached, and a connection area that connects the close contact area and the main body to each other. A needle tip of the needle tube protrudes from the close contact area, and a parting line is formed on the securing section. The outer peripheral surface of the close contact area has no parting lines.

         11 . A syringe and needle assembly, comprising:
 a needle tube having a needle tip configured to puncture a living body; and   a syringe formed integrally with the needle tube,   the syringe including a main body configured to be filled with a drug and a securing section that is formed integrally with the main body,   the securing section having a close contact area that has an outer peripheral surface, which is configured to contact an inner surface of a cap when the cap is attached, and a connection area,   wherein the connection area connects the close contact area and the main body to each other,   wherein a needle tip of the needle tube protrudes from the close contact area, and   wherein a parting line is formed on the securing section and the outer peripheral surface of the close contact area has no parting lines thereon.   
     
     
         12 . The syringe and needle assembly according to  claim 11 , wherein the parting line is located at an interface between the close contact area and the connection area. 
     
     
         13 . The syringe and needle assembly according to  claim 11 , wherein the connection area includes a reduced diameter portion that has a smaller diameter than a diameter of the close contact area. 
     
     
         14 . The syringe and needle assembly according to  claim 11 , wherein an outer surface of the reduced diameter portion extends transverse to a longitudinal axis of the needle. 
     
     
         15 . The syringe and needle assembly according to  claim 11 , wherein the parting line is located between the close contact area and the connection area. 
     
     
         16 . The syringe and needle assembly according to  claim 11 , further comprising:
 the cap being attached to the syringe and needle assembly, wherein the inner surface of the cap contacts the outer peripheral surface of the close contact area.   
     
     
         17 . An insert molded syringe and needle assembly, comprising:
 a needle tube having a needle tip configured to puncture a living body; and   a syringe formed integrally with the needle tube by insert molding,   the syringe including a main body configured to be filled with a drug and a securing section that is formed integrally with the main body,   the securing section having a close contact area that has an outer peripheral surface, which is configured to contact an inner surface of a cap when the cap is attached, and a connection area,   wherein the connection area connects the close contact area and the main body to each other,   wherein a needle tip of the needle tube protrudes from the close contact area, and   wherein a parting line, resulting from formation of the syringe and needle assembly within the mold, is formed on the securing part such that the outer peripheral surface of the close contact area has no parting lines thereon.   
     
     
         18 . The syringe and needle assembly according to  claim 17 , wherein the parting line is located at an interface between the close contact area and the connection area. 
     
     
         19 . The syringe and needle assembly according to  claim 17 , wherein the connection area includes a reduced diameter portion that has a smaller diameter than a diameter of the close contact area. 
     
     
         20 . The insert molded syringe and needle according to  claim 17 , wherein an outer surface of the reduced diameter portion extends transverse to a longitudinal axis of the needle. 
     
     
         21 . The insert molded syringe and needle according to  claim 17 , wherein the parting line is located between the close contact area and the connection area. 
     
     
         22 . The insert molded syringe and needle according to  claim 17 , further comprising:
 the cap being attached to the syringe and needle assembly, wherein the inner surface of the cap contacts the outer peripheral surface of the close contact area.
