The evaporative pad is made of a woven or non-woven fabric capable of transporting liquid by capillary action. Preferably cotton, synthetic The fibers and wood pulp fibers are entangled with a wet strength binder.

1 and 2, the cover member 24 is shown at the upper portion 92.
It consists of a somewhat conical member 91 with a Z-shaped body having a plurality of air circulation openings 93. What about each of the openings 93? ,! number of vertical slots 93. Consists of a.

FIG. 2 is a partially cutaway front view of the cover member 24 with an internal circular flange 95 depending from the top 92 of the cover member 24 and an external circular flange 96 also depending from the top 92 of the cover member 24. This outer flange furthermore has at least one stop member 97 .

In FIG. 5, a pad holding member 20 (including a pad,
(not shown) is removably held within the cover member in the following manner. That is, align the volatilization pad holding member 20 near the top of the cover member 24. Side wall segment 6
4 is arched like the main body 91 of the cover member. Moving pad retaining member 20 toward top 92 engages arched end 66 of sidewall segment 64 with internal flange 95 . Flexible, elastic sidewall segment 6
This merging is accomplished by slightly bending 4 outward. Similarly, engage circumferential projections 72 on skirt 71 with projections on the interior of body 91 of cover member 24. The volatilization pad retaining member 20 is thus rotationally engaged within the cover member 24. A circular flange 96 provides a rotating surface for the arcuate portion 65 of the sidewall segment 64 and opens the opening 93.
The stop member is adapted to limit rotation of the volatilization pad retaining member 20 when the sidewall segment 1.64 mates with the channel 82 or when the sidewall segment 1.64 completely blocks the opening 93. The volatilization pad retaining member 20 (including the volatilization pad) is retained within the cover member 24 during manufacture and assembled into one piece during shipping and use.

As mentioned above, during shipping (and when not in use) the sealing cap 18 is connected to the neck 32 of the container 12.

In this shipping or non-use condition, the lower end of shaft 68 rests loosely on shoulder 54 of sealing cap 18, standing skirt 52 is received within shaft 68, and circular projection 70 is in frictional engagement. bring about.

In use, the user simply removes the cover member-vaporization pad retainer assembly, then removes the sealing cap 18, and finally replaces it with the assembly described above. Shaft 68 receives neck 32 of container 12 and mating surfaces 34 and 70 engage. Additionally, the circular tongue 73 of the central base 630 is curled upwardly and compressively engaged with the upper portion 42 of the insert member 14. The tongue 73 need not be elastic, but it does need to be flexible in conjunction with the slot 84 therein. Core 16 has a capacity of N12
The aroma composition is moved from the container 12 to the volatilization pad 22 at the point where it connects between the pad holding member 20 and the volatilization pad 22 .

The user can adjust the rate at which fragrance diffuses from the volatilization pad to the atmosphere by rotating cover member 24 open or closed to change the size of the air circulation passageway created by opening 93 and channel 82. Diffusion is facilitated by grooves 35 and apertures 81 with updrafts providing an air flow path to the vapor space on vaporization pad retaining member 20. By placing the volatilization pad on the raised central portion 63 of the base 61, air contact is made with the bottom of the volatilization pad, thereby creating a circular channel perpendicular to the longitudinal axis of the device 10. The force required to rotate the cover member 24 relative to the volatilization pad 20-container 12 assembly is less than the force required to rotate the volatilization pad 20 relative to the volatilization pad-container assembly. However, when stop member 97 contacts sidewall segment 64, the ill pads can rotate as a unit.

This can be prevented by having a stop on the internal surface of shaft 68 that cooperates with flange 34 to limit rotation.

The fragrance dispenser and its parts of the present invention include embodiments not explicitly described as long as they share the same technical idea.
