Abstract
Abstract An air-treating device is disclosed in which a plurality of sealed packets containing a solid air-treating agent is supported in a hollow container having at least one opening through which individual packets are inserted or removed from the container. The individual sealed packets each have a removable wall portion or cover for exposing the air-treating agent contained therein, so that individual packets, stored in the container, can be selectively removed from the container and opened to expose the air-treating agent therein. The opened packets can then be replaced in the container, adjacent the opening therein, for support and storage in the container while the vapors from the solid air-treating agent in the opened packet escape from the container into the surrounding atmosphere.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
94 words
An air-treating device comprising a hollow container, a plurality of sealed packets supported within said container and respectively containing solid air-treating agent, said packets having a selectively removable wall portion for exposing said air-treating agent to the atmosphere, said container having at least one opening through which individual packets are inserted or removed from said container, whereby an individual packet having exposed solid air-treating agent therein is adapted to be supported in said container adjacent said opening to permit vapors from said solid air-treating agent to escape from said container into the surrounding atmosphere.
Claim 2
Dependent Claim
94 words
An air-treating device comprising a hollow container, a plurality of sealed packets supported within said container and respectively containing solid air-treating agent, said packets having a selectively removable wall portion for exposing said air-treating agent to the atmosphere, said container having at least one opening through which individual packets are inserted or removed from said container, whereby an individual packet having exposed solid air-treating agent therein is adapted to be supported in said container adjacent said opening to permit vapors from said solid air-treating agent to escape from said container into the surrounding atmosphere.
Claim 3
Dependent Claim
44 words
The air-treating device as defined in claim 1 wherein said container includes a movably mounted cover for selectively opening and closing said container, said cover having a plurality of apertures therein to permit vapors from said solid air-treating agent to escape from said container.
Claim 4
Dependent Claim
59 words
The air-treating device as defined in claim 2 wherein said container includes opposite end portions, said opening being located at one of said end portions, said container having a second opening therein adjacent the other of said end portions, and said container having means adjacent said second opening for supporting a packet therein for selective removal from said container.
Claim 5
Dependent Claim
57 words
The air-treating device as defined in claim 3 wherein each of said packets includes a laterally-extending flange portion about substantially its entire periphery and said means at said second opening includes an inwardly-directed flange about a substantial portion of its periphery for engaging the flanges on one of said packets to support said packets in said opening.
Claim 6
Dependent Claim
50 words
The air-treating device as defined in claim 4 wherein said packets and said container are respectively dimensioned to permit said packets to fit within said container in a single stack, with one packet supported upon another and the lowermost packet supported in said opening by the cooperation of said flanges.
Claim 7
Dependent Claim
43 words
The air-treating device as defined in claim 5 wherein said second opening and its associated flange have a predetermined configuration selected to permit the lowermost packet in said container to be removed therefrom by sliding said packet laterally with respect to said stack.
Claim 8
Dependent Claim
21 words
The air-treating device as defined iN claim 6 wherein said container and said packets are generally rectangular when viewed in plan.
Claim 9
Dependent Claim
21 words
The air treating device as defined in claim 3 including means for supporting said container on a wall or the like.
Claim 10
Dependent Claim
16 words
The air-treating device as defined in claim 8 wherein said last mentioned means comprises a magnet.
Claim 11
Independent Claim
157 words
A device for use in treating air comprising a hollow container adapted to receive and support a stack of individual sealed packets having solid air-treating agent contained therein, said container including upper and lower ends and having a first opening at said upper end, support wall means for said stack of packets at said lower end, and a wall member extending from said upper end towards said support wall means and spaced therefrom to define a slot in said container adjacent said support wall means through which the lowermost of said packets, supported by said means in said stack, may be removed from the container, whereby said removed packet can be opened to expose said air-treating agent to the atmosphere and then returned to said container through said first opening for support on the top of said stack while vapors from said exposed air-treating agent escape from the container into the surrounding atmosphere through said first opening.
Claim 12
Independent Claim
157 words
A device for use in treating air comprising a hollow container adapted to receive and support a stack of individual sealed packets having solid air-treating agent contained therein, said container including upper and lower ends and having a first opening at said upper end, support wall means for said stack of packets at said lower end, and a wall member extending from said upper end towards said support wall means and spaced therefrom to define a slot in said container adjacent said support wall means through which the lowermost of said packets, supported by said means in said stack, may be removed from the container, whereby said removed packet can be opened to expose said air-treating agent to the atmosphere and then returned to said container through said first opening for support on the top of said stack while vapors from said exposed air-treating agent escape from the container into the surrounding atmosphere through said first opening.
Claim 13
Dependent Claim
100 words
The device as defined in claim 10 wherein said packets each have an upper end portion and a peripheral flange extending laterally outwardly thereof, and wherein said support wall means comprises a generally U-shaped wall member opening towards said slot, said U-shaped wall member including bight and leg portions adapted to engage the peripheral flange of the lowermost of the packets in said stack, thereby to support said packet in said container, the opened end of said U-shaped wall member being directed towards and below said slot to permit removal of said lowermost packet from said container through said slot.
Claim 14
Dependent Claim
60 words
The device as defined in claim 11 wherein said container includes a movably mounted cover adjacent said upper end portion for selectively opening and closing said first opening, said cover having a plurality of apertures therein to permit vapors from exposed solid air treatment agent in the uppermost packet of said stack to escape from said container into the atmosphere.
Claim 15
Dependent Claim
19 words
The device as defined in claim 12 including means for supporting said container on a wall or the like.
Claim 16
Dependent Claim
15 words
The device as defined in claim 13 wherein said last mentioned means comprises a magnet.
Claim 17
Dependent Claim
60 words
The device as defined in claim 12 including in combination, a plurality of sealed packets supported within said container in a stack, said packets having chamber means formed therein for containing said solid air treating agent and extending downwardly from said peripheral flange, said chamber means having a predetermined configuration to fit between the legs of said U-shaped wall member.
Claim 18
Dependent Claim
44 words
The device as defined in claim 15 wherein said chamber means has an opening at said upper end portion of the packet for exposing said air-treating agent therein and wherein a selectively removable cover sheet is secured to said packet to cover said opening.
