Abstract
Abstract A vapor diffusing device comprising a base and a closure or cover which are detachable from each other, the base having a bottom wall and an upstanding annular sidewall with the upstanding sidewall having spaced openings therein. Means on the interior of the upstanding sidewall providing a plurality of vertically spaced ledges. The cover is adapted to be positioned so that when it is in its fully lowered position the cover provides vapor sealing engagement with the base and when the cover is raised with respect to the base it is supported in its raised position on the vertically spaced ledges to provide vapor passages through the spaced openings.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
108 words
A vapor diffusing device compirsing a base and a closure or cover which are detachable from each other, said base having a bottom wall and an upstanding annular side wall with said upstanding sidewall having spaced openings therein, means on the interior of said upstanding sidewall providing a plurality of vertically spaced apart ledges, said cover adapted to be positioned so that when in its fully lowered position the cover provides vapor sealing engagement with said base and when said cover is raised with respect to said base it is supported in its raised position on said vertically spaced ledges to provide vapor passages through said spaced openings.
Claim 2
Dependent Claim
108 words
A vapor diffusing device compirsing a base and a closure or cover which are detachable from each other, said base having a bottom wall and an upstanding annular side wall with said upstanding sidewall having spaced openings therein, means on the interior of said upstanding sidewall providing a plurality of vertically spaced apart ledges, said cover adapted to be positioned so that when in its fully lowered position the cover provides vapor sealing engagement with said base and when said cover is raised with respect to said base it is supported in its raised position on said vertically spaced ledges to provide vapor passages through said spaced openings.
Claim 3
Dependent Claim
57 words
A device as set forth in claim 1 in which said vertically spaced apart ledges are a plurality of grouped vertical, radially spaced apart ribs and in which certain of said ribs in each of said group also provide a stop means to prevent further rotation of the closure in one direction while resting on the ledges.
Claim 4
Dependent Claim
35 words
A device as set forth in claim 1 in which the cover has locking lugs adapted to engage means on the base for detachably locking said cover to said base in a vapor sealing position.
Claim 5
Dependent Claim
35 words
A device as set forth in claim 3 in which the locking lugs are adapted to rest on said vertically spaced ledges to hold the cover in elevated or raised positon relative to the base.
Claim 6
Dependent Claim
101 words
A device as set forth in claim 2 in which the cover has locking lugs adapted to engage means on the base for detachably locking said cover to said base in a vapor sealing position and in which said locking lugs are adapted to rest on the ribs to maintain the cover at different elevated positions with adjacent ribs of each group providing stop means to prevent further rotation of the closure in one direction while resting on the ledges, the positioning of said cover at different elevated positions serving to provide increased or decreased vapor passages through said spaced openings.
Claim 7
Dependent Claim
91 words
A device as set forth in claim 2 in which each group of said radially spaced ribs comprises at least three ribs with the first and second ribs having the tops thereof at different heights to serve as ledges for supporting the cover in two raised positions and with the second rib and the third rib also preventing rotation of the cover in one direction while resting on the first rib and second rib respectively, and with the top of the third rib extending above the top of the second rib.
Claim 8
Dependent Claim
26 words
A device as set forth in claim 6 in which the third rib also serves to guide the cover when it is inserted into the base.
Claim 9
Dependent Claim
47 words
A device as set forth in claim 6 in which the cover has locking lugs with sloping tops which when the cover is rotated clockwise lock in a camming action with the means on the base to hold the cover in fully closed and vapor sealing position.
Claim 10
Dependent Claim
35 words
A device as set forth in claim 8 in which the base has an annular groove which receives the annular lip on the bottom of the cover when the cover is in vapor sealing position.
Claim 11
Dependent Claim
39 words
A device as set forth in claim 9 in which the bottom wall of the base has a centrally raised bottom portion defining a well and provided with bosses to which the deodorizing material is secured when it hardens.
Claim 12
Dependent Claim
39 words
A device as set forth in claim 6 in which the underside of the base has a recessed portion which has inwardly extending bosses for holding the base while the cover is initially secured thereto in a locked position.
Claim 13
Dependent Claim
27 words
A device as set forth in claim 1 in which said cover has an opening in its upper end and means for closing said upper end opening.
