A rotatable ring is provided which has an aperture which in one position is sealed and in another open to release volatilizable material. The halves may be connected by a post upon which a donut shaped disc of fragrant material can be mounted.

Description

~.X8~7~

This invention relates to an air treating device.
One of the air treating devices on the market under the trademark "Sneaker Balls" is in the shape of a small ball of a size suitable for insertion into a sneaker. The ball is formed from -two hemispheres between which a removable ring is located. A disc o~ a volatilizable air treating compound is placed loosely within the ball and the ring acts as a seal to prevent premature volatilization of the air treating compound.
The user must separate the hemispheres, remove the ring and then reassemble the hemispheres to use the item. If it is desired to seal the ball, the ring, which may by then have been lost, must be replaced.
A disadvantage of the foregoing con-struction is the inconvenience of disassembling and reassembling the components to remove or replace the sealing ring.
A further disadvantage is that these small balls are attractive to children who may easily open them. Some air treating compounds are toxic if eaten by a small child.
Another disadvantage is that the air freshening compounds are placed loosely within the balls where they rattle around and also are not located in the best position for utilization.
The object of this invention is to overcome the foregoing disadvantages.
The invention is based on the idea of connecting the two halves of a hollow ball containing the volatilizable material firmly together, and providing a rotatable ring into an aperture. In one position of the ring the aperture is open to release the volatilizible material.

In another position it is sealed. The halves may conveniently be connected by a post which is axial to the axis of rotation of the ring and this post provides a convenient mounting for donut shaped discs of fragrant material.
This invention in one aspect more specifically provides an air treating device comprising two interacting bodies joining along a circular join line to provide a hollow container for a volatilizable air treating compound, a rotatable annular ring at the circular join line, said annular ring having at least one aperture for the passage of volatilized air treating compound, means disposed interiorly of said annular ring to provide an opening in register with said aperture at one position of the annular ring and for sealing said aperture at another position of the annular ring and means for connecting said bodies together to prevent easy access to the volatilizable air treating compound.
In a preferred aspect a post is'provided -extending axially with respect to the axis of rotation of the annular ring to suspend a donut shaped disc of volatilizable air treating compound substantially in the plane of the rotatable disc.

Figure 8 is a perspective view illustrating the use of an air treating device in accordance with this invention;
Figures 9 to 12 are elevation views illustrating air treating devices simulating various miniature game balls.
Referring now the Figures 1 to 4, the air treating device illustrated comprises a first hollow body 10 and a second hollow body 11 joining along join line 12. A rotatable annular ring 13 illustrated in Figures 2 and 5 is located at the join line. Body 10 has projections 14 which abut similar projections 15 on body 11 to provide a seat for rotatable ring 13. The pairs of projections 14 and 15 are spaced to leave openings 1~. Ring 13 has diametrically opposed apertures 17 and 17a which at one position of ring 13 are in alignment with openings 16 and at another position of ring 13 are sealed by projections 14 and 15.
Projections 1~ and 15 should be arranged so that both apertures 17 and 17a are either open to release the volatilizable air treating material or closed.
Preferably ring 13 has knurled sections 18 to facilitate rotation of the annular ring.
Hollow bodies 10 and 11 are joined together by providing a pin and socket connection or other suitable means. For example, body 10 has a pin 19 mounted on prong 20 which engages with socket 21 which is within prong 22. Prongs 20 and 22 combine to provide a supporting post 23 upon which a donut shaped pad of air freshening material may be mounted. In order to make the device child resistant, pin 19 may be cemented into socket 21 or som0 other connection may be used such as by providing pin 19 with an o~

enlarged head and undercutting socket 21. Prongs 20 and 22 extend internally from the centres of the hemispherical hollow bodies 10 and 11 and have flutes 24 which not only give post 23 additional stability but maintain pad 23 substantially in the plane of ring 13 so that air flowing through one of holes 17 and 17a to the other flows across the surface of pad 23. Pad 23 is therefore located in an optimum position for the purpose of achieving volatilization from both surfaces.
Pad 23 may be of paper, cardboard or sponge impregnated or coated with conventional air freshening and/or odour treating ingredients of a volatilizable nature.
Figure 7 illustrates an alternative embodiment in which projections 14a extending from body lOa are recessed as illustrated to leave a pair of projections 25 and 26 to receive a prong 27 in interlocking fashion extending from projection 15a. This interlock may help strengthen the structure and make it more child resistant. It will be appreciated that it is virtually impossible to provide a structure tha-t is completely childproof to a determined child. Never-theless, it is an important advantage to provide resistance to easy access.
As shown in Figure 8, ring 13 is rotated by hand so that apertures 17 and 17a are in alignment with the hole 16 to permit volatilizable deodorizing or air freshening material to escape. It may also quickly be rotated to a sealed position in which apertures 17 and 17a are aligned with projections 14 and 15.
This not only provides an advantage when the device is initially placed into use. It enables the life and potency of the air freshening material to be extended by easily closing off apertures 17 and 17a when freshening or deodorizing is not required.

Figure 9 shows a representation oE a tennis ball. Figure 10 is intended to simulate a basket ball and Figure 11 a golf ball. Each of the balls illustrated in Figures 9, 10 and 11 may, for example, be about 38 mm. in diameter.
Figure 12 shows a representation of a football with a minimum diameter of 25 mm. and a length of 50 mm.
~ further advantage of a structure in accordance with this invention is that retaining the ring as part of a ball of the type shown in Figures 9 to 12, as compared with a structure in which the ring is removed, helps to retain the appearance of a game ball.
