Scent sampler
A scent sampler has a compressible and expandable housing in which there is a chamber containing a resilient, compressible, absorbent, elastic reservoir for absorbing a scented liquid. The housing is formed from two bin-like members made of a form sustainable material, one inverted relative to and telescopically captured within the other for relative reciprocation. Squeezing of the housing urges the housing members to telescope toward one another thereby reducing the volume and increasing the pressure in the chamber for forcing vapor in the chamber into the ambient environment through an opening in the housing.
1. A scent sampler comprising
a compressible and expandable housing having top and bottom members, one inverted relative to and telescopically mounted within the other for relative reciprocation along an axis, between maximum and minimum separation of said top and bottom members, each of said top and bottom members comprising a major wall substantially transverse to said axis and a circumferential wall extending orthogonally inwardly from said major wall in a direction parallel to said axis,
said major wall of said top member being a ceiling of said housing and said major wall of said bottom member being a floor of said housing,
said housing having a chamber of variable volume enclosed by said ceiling, said floor, said circumferential wall of said top member and said circumferential wall of said bottom member,
said housing having an aperture through which air can travel between said chamber and the ambient environment,
an outer surface of said circumferential wall of said top member being in frictional sliding engagement with an inner surface of said circumferential wall of said bottom member,
and a resilient, compressible, absorbent, elastic reservoir within said chamber for absorbing a scented liquid, said reservoir having a dimension greater than said minimum separation so that during squeezing of said top and bottom members toward one another, said reservoir is compressed and releases into said chamber a vapor of said scented liquid which forms a mixture with the air in said chamber, at least a portion of said mixture being released into the ambient environment through said aperture, and upon cessation of said squeezing said reservoir urges said top and bottom members apart toward maximum separation as said reservoir returns to an uncompressed state drawing ambient air from the ambient environment into said chamber, wherein said bottom member has, along an edge of its circumferential wall distal from its floor, a shoulder extending inwardly in a direction generally parallel to said floor, and said top member has, along an edge of its circumferential wall distal from said ceiling, a lip extending outwardly in a direction generally parallel to said ceiling in interfering relationship to said shoulder for capturing said top member within said bottom member and preventing complete separation of said top member and said bottom member.
2. A scent sampler according to claim 1 wherein at least one of said top member and said bottom member is made of a flexible resilient material so that said shoulder of said top member can be forced past said lip of said bottom member when said circumferential wall of said top member is inserted into said bottom member.
3. A scent sampler according to claim 1 wherein said ceiling has a shoulder engageable with said edge of said bottom member circumferential wall for limiting relative inward movement between said top member and said bottom member.
4. A scent sampler according to claim 1 wherein said reservoir comprises a hydrophilic material.
5. A scent sampler according to claim 1 wherein said reservoir comprises a spongy material.
6. A scent sampler according to claim 1 wherein said floor of said bottom member and said ceiling of said top member are substantially parallel, and said reservoir, when fully expanded, has a dimension parallel to said axis substantially equal to the distance between said ceiling and said floor at maximum separation.
7. A scent sampler according to claim 1 wherein said ceiling is generally symmetric in shape to said floor.
8. A scent sampler according to claim 1 wherein one of said ceiling and said floor has a raised boss on its outer surface through which said aperture passes.
9. A scent sampler according to claim 8 further comprising a label with an opening congruent to a circumference of said raised boss, said raised boss being receivable within said label opening for alignment of said label on said one of said ceiling and said floor.
10. A display comprising a scent sampler according to claim 1 and a planar sign having an opening with an inner edge congruent to a profile of said circumferential wall of said top member, and sized to enable said sampler to be pressed into said sign opening with an edge of said sign opening captured within a groove between said top member and said bottom member whereby said top member and said bottom member can be squeezed together for compressing said reservoir.
