Abstract
Abstract A loose leaf binder is provided which incorporates two covers hingedly connected to an outer curved spine and a flat inner spine by means of peripheral welds. Paper retaining means are provided on the inner spine and at least one portion of the outer spine is removable to form a window through which a label inserted between the outer and inner spines is visible. The removable portion is defined by line welds produced during production of the peripheral welds.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
105 words
A loose leaf binder comprising an outer curved spine, two covers hingedly connected thereto, a flat inner spine, connecting means hingedly connecting said inner spine to said covers, said connecting means being welds extending substantially along the hinge lines and between said coVers and said outer spine, paperretaining means disposed on said inner spine, and at least one portion of said outer spine defining an enclosed segment which is characterized by a peripheral line of weakness, so that said enclosed segment can be readily removed to form a window through which a subadjacent indicia bearing strip inserted between said outer and inner spines is visible.
Claim 2
Dependent Claim
105 words
A loose leaf binder comprising an outer curved spine, two covers hingedly connected thereto, a flat inner spine, connecting means hingedly connecting said inner spine to said covers, said connecting means being welds extending substantially along the hinge lines and between said coVers and said outer spine, paperretaining means disposed on said inner spine, and at least one portion of said outer spine defining an enclosed segment which is characterized by a peripheral line of weakness, so that said enclosed segment can be readily removed to form a window through which a subadjacent indicia bearing strip inserted between said outer and inner spines is visible.
Claim 3
Dependent Claim
31 words
A binder as claimed in claim 1 wherein the removable enclosed segment is defined by at least one line weld in the outer spine, said line weld surrounding a closed area.
Claim 4
Dependent Claim
30 words
A binder as claimed in claim 2, wherein a peripheral weld extends around said two covers and said line weld is of substantially the same depth as said peripheral weld.
Claim 5
Dependent Claim
20 words
A binder as claimed in claim 2 wherein there are a plurality of removable enclosed segments having the same dimensions.
Claim 6
Dependent Claim
35 words
A binder as claimed in claim 2 wherein there are a plurality of removable enclosed segments, said segments being vertically spaced from each other such that each segment is wholly apart from the other segments.
Claim 7
Dependent Claim
17 words
A binder as claimed in claim 5 wherein said removable enclosed segments all have the same dimensions.
Claim 8
Dependent Claim
33 words
A binder as claimed in claim 2 wherein the outer spine consists of semi-rigid weldable material enclosed in flexible weldable material, said line weld having joined together said material constituting the outer spine.
Claim 9
Dependent Claim
39 words
A binder as described in claim 1, wherein the width of the indicia bearing strip is greater than that of the inner spine so that said strip assumes a curved formation corresponding to the curvature of the outer spine.
Claim 10
Dependent Claim
17 words
A binder as claimed in claim 1, wherein the window is in the form of a circle.
Claim 11
Dependent Claim
21 words
A binder as claimed in claim 1, wherein the exterior of said covers and inner spine is formed of weldable material.
Claim 12
Dependent Claim
140 words
A loose leaf binder comprising an outer curved spine, two covers hingedly connected thereto, a flat inner spine, connecting means hingedly connecting said inner spine to said covers, said connecting means being welds extending substantially along the hinge lines between said covers and said outer spine, paper-retaining means disposed on said inner spine, said outer spine consisting of semi-rigid weldable material enclosed in flexible weldable material, at least one portion of said outer spine defining an enclosed segment which is characterized by a peripheral line of weakness, so that said enclosed segment can be readily removed to form a window through which a subadjacent indicia bearing strip inserted between the inner and outer spines is visible, said removable enclosed segment being defined by at least one line weld in said outer spine, said line weld surrounding a closed circular area.
Claim 13
Dependent Claim
140 words
A loose leaf binder comprising an outer curved spine, two covers hingedly connected thereto, a flat inner spine, connecting means hingedly connecting said inner spine to said covers, said connecting means being welds extending substantially along the hinge lines between said covers and said outer spine, paper-retaining means disposed on said inner spine, said outer spine consisting of semi-rigid weldable material enclosed in flexible weldable material, at least one portion of said outer spine defining an enclosed segment which is characterized by a peripheral line of weakness, so that said enclosed segment can be readily removed to form a window through which a subadjacent indicia bearing strip inserted between the inner and outer spines is visible, said removable enclosed segment being defined by at least one line weld in said outer spine, said line weld surrounding a closed circular area.
Claim 14
Dependent Claim
21 words
A binder as claimed in claim 11 wherein said flexible weldable material and said semi-rigid weldable material comprise a synthetic resin.
Claim 15
Dependent Claim
13 words
A binder as claimed in claim 12 wherein said resin is polyvinyl chloride.
