Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 183 words
A cleansing receptacle of the type used for cleaning the several components of capillary writing pen parts, comprising: A. a container, adapted to be partially filled with cleaning solution, having a closed end and an open end, a cover for said open end and having coupled thereto a holder adapted for reception of parts to be cleaned, wherein; B. said cover and holder coupling comprises a pin extending axially and inwardly from said cover through a complementary axial hole within said holder, said holder being axially slidable thereupon wherein said pin at its distal end includes means to limit axial displacement, and; C. said container further including a plurality of ribs formed axially extending from said closed end upon its inner walls operable to axially support and limit the inward displaceability of said holder inside and near the top of said container when said cover and holder assembly has been fitted to said container, thereby completely enclosing said holder by said cover and said container and further maintaining said pen parts above said cleaning solution when said assembly is in an upright position.
Claim 2
Dependent Claim 183 words
A cleansing receptacle of the type used for cleaning the several components of capillary writing pen parts, comprising: A. a container, adapted to be partially filled with cleaning solution, having a closed end and an open end, a cover for said open end and having coupled thereto a holder adapted for reception of parts to be cleaned, wherein; B. said cover and holder coupling comprises a pin extending axially and inwardly from said cover through a complementary axial hole within said holder, said holder being axially slidable thereupon wherein said pin at its distal end includes means to limit axial displacement, and; C. said container further including a plurality of ribs formed axially extending from said closed end upon its inner walls operable to axially support and limit the inward displaceability of said holder inside and near the top of said container when said cover and holder assembly has been fitted to said container, thereby completely enclosing said holder by said cover and said container and further maintaining said pen parts above said cleaning solution when said assembly is in an upright position.
Claim 3
Dependent Claim 29 words
A cleansing receptacle as in claim 1 wherein said means to limit axial displacement comprise a barb-like configuration on the distal end of said axially and inwardly extending pin.
Claim 4
Dependent Claim 49 words
A cleansing receptacle as in claim 2 wherein said barb-like configuration comprises a pair of barbs divided about an axial plane of said pin, whereby said barbs can be squeezed together to permit said distal end of said pin to pass through said complementary axial hole within said holder.
Claim 5
Dependent Claim 90 words
A cleansing receptacle as in claim 1 wherein said means to limit axial displacement of said holder further includes barb-like projections at the distal end of said pin, together with annular rib means at the fixed end of said pin whereby writing implement parts received in said holder are secured above said cleaning solution between said holder and said annular rib means when said cover and holder assembly is fitted upon said container, and said holder is supported, upon said barb-like projections, when said cover is removed from said container.
Claim 6
Dependent Claim 217 words
A cleansing receptacle of the type used for cleaning the several components of capillary writing pen parts, comprising: A. a container adapted to be partially filled with cleaning solution, having a closed end and an open end, a cover for said open end and having coupled thereto a holder adapted for reception of parts to be cleaned, wherein: B. said cover and holder coupling comprises a pin extending axially and inwardly from said cover and through a complimentary axial hole within said holder, wherein said pin includes at its distal end a configuration to limit axial displacement of said holder comprising a pair of barbs divided about an axial plane of said pin, whereby said barbs can be squeezed together to permit said distal end of said pin to pass through said complementary axial hole within said holder; and C. said container further including means formed upon its inner walls, positioned upwardly from said closed end, operable to axially support and limit the inward displaceability of said holder inside and near the top of said container when said cover and holder assembly has been fitted to said container, thereby completely enclosing said holder by said cover and said container and further maintaining said pen parts above said cleaning solution when said assembly is in an upright position.
Claim 7
Dependent Claim 217 words
A cleansing receptacle of the type used for cleaning the several components of capillary writing pen parts, comprising: A. a container adapted to be partially filled with cleaning solution, having a closed end and an open end, a cover for said open end and having coupled thereto a holder adapted for reception of parts to be cleaned, wherein: B. said cover and holder coupling comprises a pin extending axially and inwardly from said cover and through a complimentary axial hole within said holder, wherein said pin includes at its distal end a configuration to limit axial displacement of said holder comprising a pair of barbs divided about an axial plane of said pin, whereby said barbs can be squeezed together to permit said distal end of said pin to pass through said complementary axial hole within said holder; and C. said container further including means formed upon its inner walls, positioned upwardly from said closed end, operable to axially support and limit the inward displaceability of said holder inside and near the top of said container when said cover and holder assembly has been fitted to said container, thereby completely enclosing said holder by said cover and said container and further maintaining said pen parts above said cleaning solution when said assembly is in an upright position.
