Abstract
Abstract A device for receiving a writing implement has a housing, a resiliently yieldable sealing member in the housing and adapted to sealingly abut against a writing tubular member of the writing implement, and a wetting member in the housing and located in spaced relationship with a pressure-equalizing passage of the writing implement as well as communicating with the passage. The resiliently yieldable member may be composed of two axially movable balls which are received in a cylindrical portion of the housing and axially limited by two axially spaced collars. The cylindrical portion may be connected with a conical extension which, in turn, may be connected with a further cylindrical portion received in the receiving opening of the housing. These portions may be of one-piece with each other so as to form a one-piece insert member.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
193 words
A device for receiving a writing implement having a body portion, and writing insert which together with said body portion bounds a pressure-equalizing passage and has a tubular writing member, the device comprising housing means bounding an inner chamber and having an opening arranged for receiving the body portion of the writing implement and communicating with said inner chamber; a resiliently yieldable sealing member is said inner chamber of said housing means and located so that the tubular writing member sealingly abuts against said sealing member; and a wetting member in said housing means and having at least one surface which discharges a wetting medium, said surface of said wetting member being spaced from and in communication with the pressure-equalizing passage of the writing implement when the latter is inserted in the device, so that a zone of wet air is generated in the region of said pressure-equalizing passage whereby drying of a writing liquid in the latter is prevented, but at the same time the tubular writing member is sealed by said resiliently yieldable sealing member from wet air thereby dilution of the writing liquid in the writing tubular member is prevented.
Claim 2
Independent Claim
193 words
A device for receiving a writing implement having a body portion, and writing insert which together with said body portion bounds a pressure-equalizing passage and has a tubular writing member, the device comprising housing means bounding an inner chamber and having an opening arranged for receiving the body portion of the writing implement and communicating with said inner chamber; a resiliently yieldable sealing member is said inner chamber of said housing means and located so that the tubular writing member sealingly abuts against said sealing member; and a wetting member in said housing means and having at least one surface which discharges a wetting medium, said surface of said wetting member being spaced from and in communication with the pressure-equalizing passage of the writing implement when the latter is inserted in the device, so that a zone of wet air is generated in the region of said pressure-equalizing passage whereby drying of a writing liquid in the latter is prevented, but at the same time the tubular writing member is sealed by said resiliently yieldable sealing member from wet air thereby dilution of the writing liquid in the writing tubular member is prevented.
Claim 3
Dependent Claim
26 words
A device as defined in claim 1, wherein said housing means has a collar portion, said wetting member being absorbent and mounted in said collar portion.
Claim 4
Dependent Claim
69 words
A device as defined in claim 1, wherein said inner chamber bounded by said housing means has a leading portion, as considered in the direction of insertion of the writing implement, said leading portion being formed as an annular gap which communicates with the pressure-equalizing passage of the writing implement when the latter is inserted in the device, said surface of said wetting member communicating with said annular gap.
Claim 5
Dependent Claim
22 words
A device as defined in claim 1, wherein said sealing member is formed by two resiliently yieldable balls abutting against each other.
Claim 6
Dependent Claim
46 words
A device as defined in claim 4, wherein said housing means has an axis and two axially spaced collars bounding a hollow therebetween, said balls being located in said hollow bounded by said collars and movable in axial movement which is axially limited by said collars.
Claim 7
Dependent Claim
75 words
A device as defined in claim 5, wherein said housing means has an outer housing member bounding said inner chamber and having said receiving opening, and an inner housing member received in said outer housing member, said inner housing member having a leading end portion, as considered in the direction of insertion of the writing implement into the device, said leading end portion of said housing member being cylindrical and axially bounded by said collars.
Claim 8
Dependent Claim
62 words
A device as defined in claim 6, wherein said outer housing member has a wall bounding said receiving opening, said inner housing member further having an extension portion which is connected with said cylindrical leading end portion at a trailing end of the latter and has an outer diameter corresponding to the diameter of said receiving opening of said outer housing member.
Claim 9
Dependent Claim
13 words
A device as defined in claim 7, wherein said extension portion is conical.
Claim 10
Dependent Claim
43 words
A device as defined in claim 8, wherein said inner housing member further includes a cylindrical trailing end portion connected with said conical extension portion at a trailing end of the latter and circumferentially abutting against said wall of said outer housing member.
Claim 11
Dependent Claim
36 words
A device as defined in claim 9, wherein said trailing end portion of said inner housing member has a trailing end spaced from said extension portion and a conical trailing end section at said trailing end.
Claim 12
Dependent Claim
33 words
A device as defined in claim 10, wherein said conical trailing end section is arranged to abut against the body portion of the writing implement when the latter is inserted in the device.
Claim 13
Dependent Claim
38 words
A device as defined in claim 10, wherein said leading end portion, said extension portion and said trailing end portion are of one piece with each other and forms a one-piece member insertable into said outer housing member.
Claim 14
Dependent Claim
20 words
A device as defined in claim 8, wherein said conical extension portion is provided with a plurality of through-going openings.
Claim 15
Dependent Claim
65 words
A device as defined in claim 13, wherein said housing means bounds an interior hollow formed inwardly of said inner housing member and communicating with the pressure-equalizing passage of the writing implement in the inserted position of the latter, and an exterior hollow formed between said inner housing member and said outer housing member, said through-going openings communicating said exterior hollow with said interior hollow.
Claim 16
Dependent Claim
47 words
A device as defined in claim 14, wherein said housing means has a leading end, as considered in the direction of insertion of the writing implement, and a bottom portion at said leading end, said wetting member being mounted in said bottom portion of said housing means.
Claim 17
Dependent Claim
37 words
A device as defined in claim 15, wherein said wetting member mounted in said bottom portion is located outwardly of said through-going openings so as to be in communication with said exterior hollow of said housing means.
