Description

VOLATILE MATERIAL DISPENSER AND ITS HOUSING AND
CARTRIDGE
TECHNICAL FIELD
The present invention relates to a volatile material dispenser, and the housing and cartridge for the dispenser. More particularly, the present invention relates to a dispenser capable of controlling the dispensing of the volatile material and its housing and cartridge.
BACKGROUND
There are kinds of dispensers in the market that can control the dispensing of the volatile material. In such a dispenser, the volatile material is normally dispensed from a covering plate of a housing. The housing of the dispenser further comprises a regulating plate positioned on the covering plate and movable between an open position and a closed position with respect to the covering plate. Both the covering plate and the regulating plate have bores thereon. The bores of the regulating plate are aligned with the bores of the covering plate when the regulating plate is in the open position so that the volatile material is dispensed through the aligned bores of the regulating plate and the covering plate. The bores of the regulating plates and the covering plates are not aligned with each other when the regulating plate is in the closed position so that the dispensing of the volatile material is inhibited.
Normally, there exists a large or small gap between the regulating plate and the covering plate due to the production process and cost. Therefore, when the dispenser is in the closed position, the gap between bores of the regulating plate and the bores of the covering plate may act as a leakage passage through which the volatile material may be discharged. In the existing dispenser, the bores are distributed relatively uniformly on the covering plate and the regulating plate. Thus, when the dispenser is in the closed position and the bores of the regulating plate are covered by the non-bore portion of the covering plate, the distance between the bores in the regulating plate and the bores in the covering plate adjacent to the bores in the regulating plate is relatively small and the possible gaps therebetween may be distributed all over the covering plate, and therefore there may be a lot of leakage passages in the area between the bores of the regulating plate and those of the covering plate, and the dispensing of the volatile material cannot be inhibited sufficiently. In addition, the travel distance between the open position and closed position of the regulating plate of the existing volatile material dispenser is relative short, and thus the dispensing of the dispenser cannot be regulated finely.
Moreover, in the existing dispenser, the cartridge containing the volatile material is usually movable within the housing of the dispenser. Such movement of the cartridge within the housing may cause certain inconveniencies in the usage.
Therefore, there exists a need to improve the existing volatile material dispenser.

As shown in those figures, the dispenser 100 is in a generally square shape in the elevation view, and comprises a covering plate 300 and a bottom plate 200. The covering plate 300 and the bottom plate 200 are fitted together to define a chamber therebetween for containing the volatile material. The dispenser 100 further comprises a regulating plate 400 rotatably mounted under the covering plate 300. The rotation axis of the regulating plate 400 is substantially at the center of the covering plate 300 and is perpendicular to the covering plate 300.
The covering plate 300 comprises a non-bore portion 310 and a bored portion 320. The non-bore portion 310 does not have any bore, while the bored portion 320 may have any number of bores in various shapes, e.g., in the embodiment shown in the aforesaid figures, the bored portion 320 has two bores 321 and 322. The regulating plate 400 also comprises a non-bore portion 410 and a bored portion 420. The non-bore portion 410 does not have any bore, while the bored portion 420 may have any number of bores in various shapes, such as bores 421. The bored portion and the non-bore portion of the covering plate 300 and the regulating plate 400 are arranged in a concentrated distribution. The term "concentrated distribution" means that each of the bored portion and the non-bore portion occupies a considerably large area, such as 1/2 or 1/4 of the covering plate 300 or the regulating plate 400. In the embodiment shown in figures 1-4, the bored portion 320 and the non-bore portion 310 are generally divided by a diagonal line extending from the upper left corner to the lower right corner of the covering plate 300, wherein the bored portion 320 is located at the lower left of the covering plate 300, while the non-portion 310 located at the upper right of the covering plate 300. In the embodiment shown in figures 1-4, the bored portion 420 and the non-bore portion 410 of the regulating plate 400 are divided by a straight line extending through the rotation center of the regulating plate 400, each substantially occupies a half of the regulating plate 400.
The covering plate 300 further comprises an arc-shaped guide slot 330 positioned outside the non-bore portion 310 and extending around the rotation axis of the regulating plate. The regulating plate 400 comprises a tab 430 extending out through the guide slot 330. The regulating plate 400 rotates around its rotation axis between the open position and the closed position with respect to the covering plate 300 when the tab 430 is moved by a user along the guide slot 330. In the position as shown in Fig. 1, the regulating plate 400 is in the closed position in which the bored portion 420 of the regulating plate 400 is covered by the non-bore portion 310 of the covering plate 300, while the bored portion 320 of the covering plate 300 is also covered by the non-bore portion 410 of the regulating plate 400. Therefore, all the bores of the regulating plate 400 are covered when the regulating plate 400 is in the closed position, and thus the volatile material in the chamber cannot be dispensed through the regulating plate 400. In the position as shown in Fig. 3, the regulating plate 400 is in the open position, wherein the bored portion 420 of the regulating plate 400 is aligned with the bored portion 320 of the covering plate 300. Therefore, when the regulating plate 400 is in the open position, the volatile material in the chamber can be dispensed through the bores of the regulating plate 400. In the position as shown in Fig. 2, the regulating plate 400 is in a partially open position between the open position and the closed position. When the regulating plate 400 is in the partially open position, a portion of the bored portion 420 of the regulating plate 400 is covered by the non-bore portion 310 of the covering plate 300, and the remainder of the bored portion 420 is aligned with the bored portion 320 of the covering plate 300. When the regulating plate 400 is in a partially open position, the dispensing rate of the volatile material is also between those in the open position and the closed position because the bored portion 420 is partially shielded. The alignment between the bored portion 420 and the bored portion 320 can be regulated by altering the position of the tab 430 within the guide slot 330so as to adjust the dispensing rate of the volatile material. In the embodiment as shown in figures 1-4, the circumferential angle of the guide slot 330 with respect to the rotation axis of the regulating plate 400, i.e., the angle between the two lines from the rotation center of the regulating plate to the opposite ends of the guide slot, is about 180 degrees. Therefore, the travel distance of the tab 430 is relatively large, and thus the dispensing level of the dispenser can be regulated accurately.
Figs. 5-7 illustrate the interior structure of one embodiment of the present invention. As clearly shown in Fig. 7, the bottom plate 200 comprises two retaining posts 230 extending upwardly from two generally diagonal positions of the bottom plate 200, and the cartridge 600 has holes 610 provided at two corresponding positions. As shown in Figs. 5-6, the two retaining posts 230 on the bottom plate 200 extend through the two holes 610 in the cartridge 600 respectively to retain the cartridge 600 in place when the cartridge 600 is mounted on the bottom plate 200.
Figs. 8-10 illustrate the interior structure of one embodiment of the present invention. As clearly shown in Fig. 10, the bottom plate 200' includes curved holders 240 positioned at both the left and right sides of the bottom plate 200' . Meanwhile, the contours 720 at the left and right sides of the cartridge 700 are adapted to mate with the contours of the inner sides of the curved holders 240. As shown in Figs. 8-9, the two curved holders 240 on the bottom plate 200' retain the contours 720 of the left and right sides of the cartridge 700 from both the left and right sides to retain the cartridge 700 in place.
