Abstract
Abstract The disclosed closure for garments and the like includes a headed male member and a companion slotted female member, both blanked out of tough, pliant plastic sheets. The male member of sheet plastic is assembled to the female member that is also of sheet plastic by inserting a male head portion of the blanked outlet into an opening in the female member having an outline that includes a transverse enlargement, then shifting the neck of the male member into a slot in the blanked opening of the female member. That opening has a guiding pair of divergent edges, leading first to a slot construction that is spaced from an end abutment of the slot. The constriction inhibits the accidental separation of the closure members, but the related portions of the closure members promote assembly and disassembly in a way to overpower the constriction when manipulated deliberately. Strips of the closures can be curved by bending the sheet material out of its plane and each strip is narrow or has narrow connections so that the strips can be flexed in their own planes.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
319 words
A closure for securing first and second elements together, said closure including first and second unitary members of tough, pliant synthetic plastic sheet material, a. one of said members having a first body portion for securement to a first element, a head, and a neck connecting said body portion and said head, said head having abutment portions projecting to opposite sides of said neck, and b. said second member having a second body portion for securement to a second element that is to be secured to the first element by the closure, said second member having an opening adjacent to said second body portion, i. said opening including a slot portion having side edges and having an abutment edge, ii. said opening also having an enlargement between said abutment edge and said second body portion, said enlargement extending beyond the side edges of said slot portion and being at least as large in the direction transverse to the side edges of the slot portion as said head when the latter is measured in the direction transverse to said neck, iii. said slot portion having a constriction at least part of which is narrower than said neck of said first member, said constriction being spaced from said abutment edge so that when said neck is received between said constriction and said abutment edge in the fully assembled condition of said first and second members, said constriction inhibits disassembly of the closure members, said narrower part of said constriction being spaced from said enlargement so that, when said head of the first member is inserted through the slot enlargement and the neck of the first member is then shifted against the narrower part of said constriction, said abutment portions of the head overlie areas of the second member to prevent the head from being pulled through said opening when said body portions are pulled for forcing said neck past said constriction.
Claim 2
Dependent Claim
319 words
A closure for securing first and second elements together, said closure including first and second unitary members of tough, pliant synthetic plastic sheet material, a. one of said members having a first body portion for securement to a first element, a head, and a neck connecting said body portion and said head, said head having abutment portions projecting to opposite sides of said neck, and b. said second member having a second body portion for securement to a second element that is to be secured to the first element by the closure, said second member having an opening adjacent to said second body portion, i. said opening including a slot portion having side edges and having an abutment edge, ii. said opening also having an enlargement between said abutment edge and said second body portion, said enlargement extending beyond the side edges of said slot portion and being at least as large in the direction transverse to the side edges of the slot portion as said head when the latter is measured in the direction transverse to said neck, iii. said slot portion having a constriction at least part of which is narrower than said neck of said first member, said constriction being spaced from said abutment edge so that when said neck is received between said constriction and said abutment edge in the fully assembled condition of said first and second members, said constriction inhibits disassembly of the closure members, said narrower part of said constriction being spaced from said enlargement so that, when said head of the first member is inserted through the slot enlargement and the neck of the first member is then shifted against the narrower part of said constriction, said abutment portions of the head overlie areas of the second member to prevent the head from being pulled through said opening when said body portions are pulled for forcing said neck past said constriction.
Claim 3
Dependent Claim
61 words
A closure in accordance with claim 1, wherein said head and said body portion of said first member are displaced in parallel planes such that, when said closure members are in said fully assembled condition, said head lies against one surface of said second member and part of said first body portion lies against the opposite surface of said second member.
Claim 4
Dependent Claim
95 words
A closure in accordance with claim 1, further including additional first and second closure members as aforesaid to constitute a multiplicity of closure members interconnected in respective rows as integral parts of two essentially planar strips of sheet material and said multiplicity of first and second closure members being distributed along their respective strips for cooperation in pairs, said strips being sufficiently narrow and thin, at least at parts thereof, so as to be readily curved out of the planes of their respective strips and so as to be readily curved in their respective planes.
Claim 5
Dependent Claim
66 words
A closure in accordance with claim 1, wherein said constriction is limited in relation to the width of said neck, taking into account the stIffness of the plastic sheet material and its proportions and pliancy, to accommodate separation of a fully assembled pair of the male and female closures in response to manual engagement and forcible shift of the respective body portions thereof toward each other.
Claim 6
Dependent Claim
55 words
A closure in accordance with claim 1, wherein at least part of the edges of said slot portion of the opening between said constriction and said enlargement converge toward said constriction, for facilitating the shift of the neck of said first member from said enlargement to said constriction in assembling said first and second members.
