Structure Of Air-Pocket Film Reel

Abstract

A structure of an air-pocket film reel includes a support holder mountable to an air-pocket film machine and an air-pocket film reel mountable to the support holder. The support holder has an end portion including at least one constraint section formed thereon. The air-pocket film reel has an end including an engagement section engageable with and thus mating the constraint section. When the air-pocket film reel is fit to the support holder, the engagement section is put into mating engagement with the constraint section of the support holder to effectively prevent slipping of the air-pocket film reel and achieve synchronous rotation of the support holder and the air-pocket film reel to thereby improve overall productivity, better sealing effect, and enhance stability.

I claim: 
     
         1 . A structure of an air-pocket film reel, comprising:
 a support holder that is adapted to be mounted to an air-pocket film machine, the support holder having an end portion comprising at least one constraint section formed thereon; and   an air-pocket film reel that is mountable to the support holder, the air-pocket film reel having an end comprising an engagement section formed thereon for mating engagement with the constraint section.   
     
     
         2 . The structure of the air-pocket film reel according to  claim 1 , wherein the support holder comprises at least one slope positioning section arranged at an end of the constraint section for securely holding and stabilizing an air-pocket film reel. 
     
     
         3 . The structure of the air-pocket film reel according to  claim 1 , wherein the constraint section is formed on a surface of the end portion of the support holder. 
     
     
         4 . The structure of the air-pocket film reel according to  claim 3 , wherein the constraint section is an elastic constraint section. 
     
     
         5 . The structure of the air-pocket film reel according to  claim 4 , wherein the engagement section comprises a through hole for receiving the constraint section to fit therein for mating engagement. 
     
     
         6 . The structure of the air-pocket film reel according to  claim 1 , wherein multiple constraint sections are included and arranged in a stepped configuration. 
     
     
         7 . The structure of the air-pocket film reel according to  claim 6 , wherein multiple engagement sections are included and are arranged in a stepped configuration corresponding to and mating with the constraint sections. 
     
     
         8 . The structure of the air-pocket film reel according to  claim 1 , wherein the support holder comprises a combination of a first support holder member and a second first support holder member coupled to the first support holder member.
