Flgure 5 is an enlarged fragmentary sectional view showlng the closure or cover locked to the base member.
Figure 6 is a fragmentary perspective view showing the locking lug on the closure and its position when being moved into locking position on the base.
Figure 7 is a broken-away perspective view showing particularly the interior of the base member.
Figure 8 is a view similar to Figure 2 and showing the cover restlng in :Lts first elevated position with respect to the base; and Figure 9 is a bottom plan view of the underside of the base.
The device consists essentially of two basic parts, namely, a base generally indicated at lO and a cover or closure member generally indicated at 12, each of which is integrally molded of a plastic material. The cover 12 is ,~, ~ -3-:
molded to provide a top annular opening 14 which is closed by a disk 15, as shown in ~ig. 2. The air treating material indicated at 16 and illustrated in dotted lines, subsequently to be described, is held secured in the base 10. The base and cover are so constructed that the cover may be locked to the base in a vapor sealing position, as shown in Eig. 2, and when in use the cover 12 is elevated or raised with respect to the base 10 to various elevations to provide increased or decreased vapor passages which are formed in the base. One o~ such elevated positions is shown in ~ig. 8.
The base 10 is generally cup-shaped and comprises a closed bottom generally indicated at 18 which consists o:~ a lower annular side wall 19 and a horizontal bottom wall 20 which has an annular central}y raised bottom portion 21 with spaced radially extending bosses 22. The closed bottom forms a pocket 24 for receiving the air treating material, as will be subsequently described, so that it is secured to the base.
m e pocket 24 includes the annular well 25 between the annular side wall 19 and the centrally raised bottom portion 21. The top of rim 23 of the side wall 19 has an annular groove 26.
Extending upwardly of the lower annular side wall 19 is an upper annular side wall generally indicated at 28 which is provided with vertically extending spaced elongated openings 30 which form the vapor passages and which also divide the upper side wall into alternate side wall sections 32 and 34, with the wall section 32 being approximately twice the width of the wall section 34. The bottom of each wall section 32 has an opening 36 which also ~orm vapcr passages.
The wall sections 32 and 34 forming the upper wall extend ~rom below the top o~ -the annular side wall 19 to the top ~038~3~7 edge which forms a scalloped-shaped rim 37 at the mouth of base member 10. The lower ends ~2 ' and 34' of the wall sections 32 and 34, respectively, incline and the upper annular side wall 28 inclines or tapers outwardly from the bottom to the top rim 37 to give the upper annular wall an outwardly flared configuration. me vertical openings 30 forming the vapor passages have an elongated tapered appearance with the greatest width adjacent the bottom o~
the opening and the top 30 ' of the opening terminates a distance below the top edge or rim 37 of the cup or base.
The inside of the upper annular wall 28 of the base is provided with five groups of inwardl~ extending vertical ribs. Each group of ribs, generally indicated at l~o, comprises three spaced ribs identif~ed by the numerals 42, 44 and 46 which are of different lengths or heights. m e first rib 42 of each group is the shortest, the third rib 46 the longest and the second or intermediate rib 44 of intermediate length. m e bottoms of the three ribs are connected by a bottom horizontal locking strip 48 which is spaced upwardly of the rim 23 of the annular bottom side wall 19 and which locking strips are engaged by the locking lugs on the cover in a camming action to lock the cover in its sealing position, as best shown in Figs. 4, 5 and 6, to be described. m e end of the locking strip 48 adjacent the rib 46 is beveled as at 4g, as best seen in Fig. 4, to facilitate engagement with the cover locking lugs.
The horizontal top edge 50 of the shortest rib 42 serves as a rest or ledge or support for the cover 12 in its first raised position, as best seen in Fig 8. The horizontal top edge 52 of the second or intermediate rib 44 ~ 5 -~03~8Q7 serves as a rest or ledge or support for the cover in its second or uppermost raised or elevated position. The second or intermediate rib 44 above the top horizontal edge 52 is inclined as at 5~i toward the wall. T~le third or longest rib 46 has a downwardly inclined top edge 5~ which is rounded as at 56 as it merges with the fron~ edge 57 of said rib. me third rib 46 serves to properly guide the cover into the base when it is inserted and in addition serves as a stop member, as will be subsequently described, as does the second or intermediate rib 44, more fully to be described in connection with the operation of the cover.
The three spaced ribs 1~2, 41~ and l~6 of each group of ribs are :~ormed on the wider side wall sections 32 of the upper portion of the base.
m e cover or closure 12 is a shell-like member having a cylindrical-shaped body 60 with an annular ring-like top wall 62 providing the central top opening 14 and open at its bottom. m e top wall ring 62 is below the annular top edge 65 of the body 60. me cylindrical body 60 is provided with a slight taper which tapers inwardly from the bottom toward the top. The outer surface o~ the cylindrical body may be ornamented with lines or other configurations to enhance its appearance. The disk 15 has an annular peripheral lip or shoulder 15 ' to engage the top wall 62 when positioned thereon and sealed thereto, with a portion of the disk extending into the opening 14, as will be described.
The annular bottom edge 66 of the cylindrical body 60 is recessed as at 67 to provide a downwardly extending lip 68 and a horizontal shoulder 69 so that when ~ ~388~7 the cover is positioned in sealing position on the base, the lip 68 enters the annular groove 26 of the rim 2~ of the lower bottom of the base, as shown in Figs 2 and 5~ to form a seal-tight ~it therewith to prevent any vapor from escaping from the interior of the sealed container. ~ -Immediately above the recessed lower rim of the cover is a plurality o~ spaced locking lugs generally indicated at 70. Five such locking lugs are shown for engagement with the five horizontal locking strips l~8. As best seen in Fig. 6, the top 72 of each locking lug slopes or inclines upwardly from the ~ront or lead edge 73 thereof toward the rear which terminates in an upward projection 71~
which serves as a stop to prevent ~urther continued rotation of the cover when in its fully closed or sealing position, as shown in Fig. 2. m e locking lugs 70 act as cams so that rotation of the cover to lock the co~er to the base in effect cams the locking lugs in locking position.
m e underside of the closed bottom of the base is best seen in Figs. 8 and 9. me raised bottom portion 21 also provides a recessed area 76 above the bottom edge 77 of the base 10 which opens downwardly and ~our arcuate-shaped bosses 78 are spacedly formed on the underside so that the base lO may be positioned on a tool or the like to hold the base in position when the cover is initially secured to the base, which is done at the plant where the parts are molded, as will be better understood from the description of the operation which ~ollows.
^~
1~)3~7 Operation The operation of the device will be understood from the foregoing description, but briefly described is as follows.
After the air treating material 16 has been secured to the base 10 in the manner hereinafter described~ the cover 12 is inserted into the base 10 with the locking lugs 70 positioned between each group of ribs 40, The third rib 46 of each group of ribs will serve to guide and properly position the lower edge of the cover relative to the base to permit easyi and accurate insertion. The lip 68 on the bottom edge 66 of the cover will ente:r the annular groove 26 on the rim 23 of the base with the shoulder 69 resting on the rim. To lock the cover to the ba~e the cover is rotated clockwise with the front edge 73 of the locking lug 70 first passing under the beveled edge 49 of the horizontal locking strip 48. As the cover is rotated clockwise the sloping top surface 72 of the locking lug 70 cams the locking lugs into locking engagement with the horiæontal locking strips 48 until the rear pro~ections 74 o~ the locking lugs engage the rear edge of the locking strips 48 which prevents ~urther clockwise rotation of the cover and thereby locks the cover to the base in a vapor-seal position~ in which position it remains during shipment and when in non-use position prevents vapor from emanating from the device. In this lowered or sealing position the cover if rotated counterclockwise will still remain in vapor seal-proof closed position as the rear edge and projection 74 of the locking lugs will engage the bottom of the first or shortest ribs 42 and the opposite edge of 1~388~7 the adjacent locking strips 48 to prevent further counter-clockwise rotation. The cover, however, will not be in a locked position.
Assuming that the cover is in locked position with the locking lugs 70 locked to the locking strips 48 and the device is to be used, the cover is rotated counterclockwise un~il the locking lugs 70 are free o~ the locking strips 48.
The cover is then raised or lifted to either first or second raised position as desired. For example, if desired to raise it to first position, as shown i~ Fig. 8, the cover is raised to the top edges 50 of the first ribs 42 and the cover is rotated counterclockwise so that the bottoms o~
the lock.ing lugs 70 rest on the top edges 50 to support the cover in lts first raised position. The rear edges and the projections 7~ of the locking lugs will engage the intermediate ribs 44 and prevent or stop further counter-clockwise rotation at this raised position. With the cover in first raised position (Fig. 8) the bottom of the cylindrical cover is above the sealing position of the cover~ thus exposing the lower portions of the vapor openings 30 as well as openings 36 to permit vapor to pass through. When greater vaporization is desired the cover 12 is raised and rotated counterclockwise so that the locking lugs 70 rest on the ledges 52 of the intermediate ribs 44 and further counterclockwise rotation of the cover being prevented in this second raised position by engagement of the rear of the locking lugs with the third ribs 46.
To close the cover, the cover is rotated counter-clockwise from any of its elevated positions so that the locking lugs are disengaged from their respective ledges and _ g _ ~0;~8~)7 the cover is lowered to its lowermost position in the base and then rotated clockwise to locking position as described.
While three ribs are shown for each group of ribs it will be understood that a fewer or greater number o~ ribs may be provided in each group o~ ribs i~ increased or decreased cover positions are desired.
Another feature o~ the invention herein is that as the cover is elevated and as the air treating material 16 in the base is used up due to its vaporization, there is no detraction from the appearance since the deteriorated or misshaped air treating material remaining in the base is substantially hidden ~rom exterior view, even when the cover or closure is in either of its raised positions.
The manner in which the volatile material or deodorizing material is put into the unit will now be described.
The cover 12 without the disk 15 thereof is locked to the base 10 by means o~ lockings lugs, etc. as previously described. mis leaves the top o~ the cover open and in this manner it is shipped to the company who will supply the volatile air treating agentJ which agent is poured into the locked container through the opening 14 in the cover. me material will then ~ill and occupy the closed bottom 18 o~
the base, including the annular well 25 as well as the pocket 24 and will extend upwardly beyond the top of the base into the cover portion but be confined within the cover or closure. The material is allowed to solidify and harden and becomes embedded in the closed bottom 18 of the base and adheres thereto. me bosses 22 serve to lock the hardened deodorizing material in the base so as ~J38807 to prevent rotation of the hardened deodorizing material when the cover is rotated. While the deodorizing material when initiall~ poured into the cover will occup~ the interior space o~' the cylindrical body of the cover, it will reduce in size as it hardens so that, it disengages from the inside wall of the cylindrical wall o~ the cover so that the cover can be rotated without disturbing the hardened deodorizing material. m e disk 15 is then permanently secured to close the opening 14 in the cover in any conventional manner.
This invention is directed to an a:ir Ereshener container or vapor diffusing device comprising a base and a cover or closure member in which the base contains a volatile material, for example, an air freshening deodori~er, and in which the closure or cover is manually displaceable with respect to the base to provide means for controlling the effective rate of volatilization or evaporation of the air treatment agent, and also wherein the cover can be positively locked with respect to the base so that it is sealed with respect to the base to prevent evaporation or volatilization of the air treating agent.
An ob;ect of this invention is to provide a device of the foregoing character where as the volatill~ation or evaporation takes pl.ace and as the air treating agent reduces in slze and its appearance deteriorates or is destroyed that it will note be visible and will be practically hidden from exterior view.
In one particular aspect the present invention provides a vapor diffusing device comprising a base and a closure or cover which is detachable from each other, said base having a bottom wall and an upstanding, annular sidewall with said upstanding sidewall havlng space~openin~s therein, means on the interior of said upstanding s:Ldewall. providing a plurality of grouped vertical radially spaced apart ribs in which certain of said ribs in each of said groups also provide stop means to prevent further rotation of the closure in one direction while resting on the ribs, 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 sa:Ld base it is ~,., .' .

the base, including the annular well 25 as well as the pocket 24 and will extend upwardly beyond the top of the base into the cover portion but be confined within the cover or closure. The material is allowed to solidify and harden and becomes embedded in the closed bottom 18 of the base and adheres thereto. me bosses 22 serve to lock the hardened deodorizing material in the base so as ~J38807 to prevent rotation of the hardened deodorizing material when the cover is rotated. While the deodorizing material when initiall~ poured into the cover will occup~ the interior space o~' the cylindrical body of the cover, it will reduce in size as it hardens so that, it disengages from the inside wall of the cylindrical wall o~ the cover so that the cover can be rotated without disturbing the hardened deodorizing material. m e disk 15 is then permanently secured to close the opening 14 in the cover in any conventional manner.
