Abstract
Abstract A packing member, in either strip or annular form, the member comprising two lip sections adjoined to form a broad planar head surface. Each of the lip sections has a base with an outer lateral surface, and a groove extends along the entire length, or circumference, of the packing member between the bases. At least one of the lip sections includes a laterally outwardly depending sealing projection having a generally laterally outwardly facing side surface and a lower surface. In a relaxed state, the lower surface is disposed generally at an angle to the outer lateral surface of the respective base so as to be non-downwardly inclined from the outer lateral surface. The sealing projection is of such volume and cross-sectional configuration that, upon application of a generally laterally inward force to the side surface, the sealing projection is deformed to form a cavity adjacent its lower surface.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
201 words
An elongate strip packing member comprising: first and second lip sections adjoined to form a relatively broad planar head surface, each of said lip sections including a base having an outer lateral surface; said packing member having a groove between said bases extending the length of said packing member and opening downwardly away from said head surface; said first lip section further including a laterally outwardly depending sealing projection, said sealing projection having a generally laterally outwardly facing side surface and a lower surface, said lower surface being adjoined to the outer lateral surface of said base of said first lip section and, in a relaxed state, being generally inclined from its laterally inner to its laterally outer extremities at an angle so as to be non-downwardly inclined from the outer lateral surface greater than or equal to 90° with respect to a line normal to said head surface, and said sealing projection being of such volume and transverse cross-section configuration that upon application of a generally laterally inward force to said side surface said sealing projection is deformed to form a cavity adjacent said lower surface, said cavity opening downwardly away from said head surface and forming a pressure trap.
Claim 2
Dependent Claim
201 words
An elongate strip packing member comprising: first and second lip sections adjoined to form a relatively broad planar head surface, each of said lip sections including a base having an outer lateral surface; said packing member having a groove between said bases extending the length of said packing member and opening downwardly away from said head surface; said first lip section further including a laterally outwardly depending sealing projection, said sealing projection having a generally laterally outwardly facing side surface and a lower surface, said lower surface being adjoined to the outer lateral surface of said base of said first lip section and, in a relaxed state, being generally inclined from its laterally inner to its laterally outer extremities at an angle so as to be non-downwardly inclined from the outer lateral surface greater than or equal to 90° with respect to a line normal to said head surface, and said sealing projection being of such volume and transverse cross-section configuration that upon application of a generally laterally inward force to said side surface said sealing projection is deformed to form a cavity adjacent said lower surface, said cavity opening downwardly away from said head surface and forming a pressure trap.
Claim 3
Dependent Claim
29 words
A packing member according to claim 1 wherein said cavity is partially defined by a laterally outer cavity surface inclined laterally outwardly from its upper to its lower extremity.
Claim 4
Dependent Claim
21 words
A packing member according to claim 1 wherein said second lip section also includes such a laterally outwardly depending sealing projection.
Claim 5
Dependent Claim
16 words
A packing member according to claim 3 further being symmetrical about a plane bisecting said groove.
Claim 6
Dependent Claim
23 words
A packing member according to claim 1 wherein said side surface is inclined slightly laterally outwardly from its upper to its lower extremity.
Claim 7
Dependent Claim
23 words
A packing member according to claim 5 wherein said lower surface and said side surface converge to form a relatively sharp leading edge.
Claim 8
Dependent Claim
22 words
A packing member according to claim 5 wherein said lower surface is joined to said side surface by a rounded corner portion.
Claim 9
Dependent Claim
22 words
A packing member according to claim 1 wherein said bases have lower base surfaces extending downwardly and laterally outwardly from said groove.
Claim 10
Dependent Claim
15 words
A packing member according to claim 1 wherein said cavity is shallower than said groove.
Claim 11
Dependent Claim
189 words
An annular packing member comprising: first and second lip sections adjoined to form a relatively broad planar head surface, each of said lip sections including a base having an outer lateral surface; said packing member having a groove between said bases extending the circumference of said packing member and opening downwardly away from said head surface; said first lip section further including a laterally outwardly depending sealing projection, said sealing projection having a generally laterally outwardly facing side surface and a lower surface, said lower surface being adjoined to the outer lateral surface of said base of said first lip section and, in a relaxed state, being generally inclined from its laterally inner to its laterally outer extremities at an angle greater than or equal to 90° with respect to a line normal to said head surface, and said sealing projection being of such volume and transverse cross-sectional configuration that upon application of a generally laterally inward force to said side surface said sealing projection is deformed to form a cavity adjacent said lower surface, said cavity opening downwardly away from said head surface and forming a pressure trap.
Claim 12
Dependent Claim
189 words
An annular packing member comprising: first and second lip sections adjoined to form a relatively broad planar head surface, each of said lip sections including a base having an outer lateral surface; said packing member having a groove between said bases extending the circumference of said packing member and opening downwardly away from said head surface; said first lip section further including a laterally outwardly depending sealing projection, said sealing projection having a generally laterally outwardly facing side surface and a lower surface, said lower surface being adjoined to the outer lateral surface of said base of said first lip section and, in a relaxed state, being generally inclined from its laterally inner to its laterally outer extremities at an angle greater than or equal to 90° with respect to a line normal to said head surface, and said sealing projection being of such volume and transverse cross-sectional configuration that upon application of a generally laterally inward force to said side surface said sealing projection is deformed to form a cavity adjacent said lower surface, said cavity opening downwardly away from said head surface and forming a pressure trap.
Claim 13
Dependent Claim
29 words
A packing member according to claim 10 wherein said cavity is partially defined by a laterally outer cavity surface inclined laterally outwardly from its upper to its lower extremity.
Claim 14
Dependent Claim
21 words
