Abstract

Abstract A tape reel comprising a lower reel member consisting of a disc-like portion and a hub which are designed as an integral part, protrusions having claw-like heads formed on the end surface of said hub and a disc-like upper reel member, whereby said upper and lower reel members can be assembled and fixed to each other by fitting the protrusions formed on the hub into the holes formed in said upper reel member.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 105 words
A tape reel comprising: a lower reel member including a disc-like portion and integral therewith a cap-like hub extending upwardly and including an integral upper end surface, flexible protrusions projecting upwardly from said upper end surface of said hub and having claw-shaped heads, and a disc-like upper reel member having holes axially disposed therein, there being respective surfaces adjacent said holes for catching said claw-shaped heads, whereby said lower and upper reel members can be assembled and tightly fixed to each other by snap fitting said protrusions formed on said hub of said lower reel member into said holes formed on said upper reel member.
Claim 2
Dependent Claim 105 words
A tape reel comprising: a lower reel member including a disc-like portion and integral therewith a cap-like hub extending upwardly and including an integral upper end surface, flexible protrusions projecting upwardly from said upper end surface of said hub and having claw-shaped heads, and a disc-like upper reel member having holes axially disposed therein, there being respective surfaces adjacent said holes for catching said claw-shaped heads, whereby said lower and upper reel members can be assembled and tightly fixed to each other by snap fitting said protrusions formed on said hub of said lower reel member into said holes formed on said upper reel member.
Claim 3
Dependent Claim 130 words
A tape reel comprising: a disc-like upper reel member, flexible protrusions projecting downwardly from said upper reel member and having claw-like heads, and a lower reel member including a disc-like flange and integral therewith an upstanding hub having an integral upper end surface and a circumferential side wall the latter of which contains a plurality of protrusion engagement holes having an axial portion extending inside said side wall from said end surface axially a given distance and then a radial portion extending radially for providing respective surfaces for catching said claw-like heads, whereby said upper and lower reel members can be assembled and tightly fixed to each other by snap fitting the protrusions formed on said upper reel member into the holes formed in the side wall of said hub.
Claim 4
Dependent Claim 130 words
A tape reel comprising: a disc-like upper reel member, flexible protrusions projecting downwardly from said upper reel member and having claw-like heads, and a lower reel member including a disc-like flange and integral therewith an upstanding hub having an integral upper end surface and a circumferential side wall the latter of which contains a plurality of protrusion engagement holes having an axial portion extending inside said side wall from said end surface axially a given distance and then a radial portion extending radially for providing respective surfaces for catching said claw-like heads, whereby said upper and lower reel members can be assembled and tightly fixed to each other by snap fitting the protrusions formed on said upper reel member into the holes formed in the side wall of said hub.
Claim 5
Dependent Claim 41 words
A tape reel as in claim 2 wherein said hub side wall has a circumferential protrusion-engagement groove extending downwardly from said end surface for said given distance and including at least a portion of each said axial portion of said holes.
Claim 6
Dependent Claim 30 words
A tape reel as in claim 2 or 3 wherein said hub has an interior which is hollow and said radial portions of said holes extend to said hollow interior.
Claim 7
Dependent Claim 40 words
A tape reel as in claim 4 wherein said side wall has a plurality of axial slots extending from said end surface said given distance as part of said axial portions of said holes and forming said radial portions thereof.
Claim 8
Dependent Claim 152 words
A tape reel comprising: a first reel member including a disc-like portion and integral therewith a hub extending axially therefrom and having an integral cap-like outer end from which a circumferential ridge projects axially outwardly, a disc-like second reel member having a central area with means complimenting said ridge for maintaining said first and second reel members radially fixedly centered relative to each other, and a plurality of circumferentially spaced protrusions projecting axially outwardly from said cap-like outer end of said hub, each said protrusion indlucing a flexible shank having at its outer end a head with a claw-like latching member extending radially from said shank, said central area of said second reel member having a plurality of circumferentially spaced through holes mating said shanks and having respective surrounding material cooperating with said latching members to effect a snap fit therebetween for fixedly securing said hub and second reel member together axially.
Claim 9
Dependent Claim 152 words
A tape reel comprising: a first reel member including a disc-like portion and integral therewith a hub extending axially therefrom and having an integral cap-like outer end from which a circumferential ridge projects axially outwardly, a disc-like second reel member having a central area with means complimenting said ridge for maintaining said first and second reel members radially fixedly centered relative to each other, and a plurality of circumferentially spaced protrusions projecting axially outwardly from said cap-like outer end of said hub, each said protrusion indlucing a flexible shank having at its outer end a head with a claw-like latching member extending radially from said shank, said central area of said second reel member having a plurality of circumferentially spaced through holes mating said shanks and having respective surrounding material cooperating with said latching members to effect a snap fit therebetween for fixedly securing said hub and second reel member together axially.
