Integral structure of cotton yarn strips and a circular frame body of a mop

Abstract

An integral structure of cotton yarn strips and a circular frame body of a mop, comprising: a circular frame body having a through hole at the center thereof; and a plurality of cotton yarn strips positioned at the bottom of the circular frame body. The top portions of the cotton yarn strips are radially arranged in a ∩-shaped way within a mold assembly of the circular frame body such that the top portions of the cotton yarn strips and the circular frame body are integrally formed. The circular frame body includes a circumferential rib at the center of each of the radial ∩-shaped parts of the cotton yarn strips such that the circumferential ribs are hidden against the ∩-shaped top portions of the cotton yarn strips to allow a tight fit of the top portions of the cotton yarn strips in the circular frame body.

1 . An integral structure of cotton yarn strips and a circular frame body of a mop, comprising:
 a) a circular frame body having a through hole at the center thereof; and   b) a plurality of cotton yarn strips positioned at the bottom of the circular frame body;   wherein the top portions of the cotton yarn strips are radially arranged in a ∩-shaped way within a mold assembly of the circular frame body such that the top portions of the cotton yarn strips and the circular frame body are integrally formed; and   wherein the circular frame body includes a circumferential rib at the center of each of the radial ∩-shaped parts of the cotton yarn strips such that the circumferential ribs are hidden against the ∩-shaped top portions of the cotton yarn strips to allow a tight fit of the top portions of the cotton yarn strips in the circular frame body.   
     
     
         2 . The integral structure of cotton yarn strips and a circular frame body of a mop as recited in  claim 1  wherein the circumferential rib includes an upright rib portion at both sides thereof, thereby creating an H-shaped positioning part. 
     
     
         3 . The integral structure of cotton yarn strips and a circular frame body of a mop as recited in  claim 1  wherein a plurality of engaging projections are formed at the internal rim of the through hole of the circular frame body. 
     
     
         4 . The integral structure of cotton yarn strips and a circular frame body of a mop in  claim 3  wherein a mounting disc fits in place at the top of the through hole of the circular frame body to create a mop head.
