Claim 4

A fog-producing disposable canister according to claim 2 wherein said closure means comprises a meltaway label.

Claim 5

A fog-producing disposable canister according to claim 1 wherein said cap has a first set of lugs extending outwardly from said cap to activate a power source in said electric fogger and a second set of lugs constructed and arranged either above or below said first set of lugs to activate a timer means in said electric fogger whereby said fogger is operated for a predetermined period of time.

Claim 6

An electric fogging apparatus comprising:

Claim 7

An electric fogging apparatus comprising:

Claim 8

(a) a housing;

Claim 9

(a) a housing;

Claim 10

(b) a canister for removable insertion into said housing comprising (1) a container having an open top which holds a fog-producing material and which is constructed of a material which will transfer heat from a heat source to said fog-producing material; (2) an insert secured in said container to close said open top and having a dome with a discharge port to allow the release of a fog; and (3) a cap attached to said container for covering said container having an opening overlying said discharge port of said insert to allow the release of a fog and having at least one lug extending from said cap for activating said electric fogger; (c) a means on said housing for receiving and replaceably holding said canister in said housing; (d) an electrical heating means in said housing for heating said canister in said housing; (e) an electrical timing means within said housing which controls said heating means whereby said heating means is operated for a predetermined period of time; and (f) an electrical switch means constructed and arranged with said timing means and said heating means for activating said timing means and said heating means, said switch means being activated by one of said lugs on said canister upon insertion and rotation of said canister in said receiving and holding means of said housing; thereby heating said canister, the heat being transferred to said fog-producing material to produce a fog which is released to an environment of use through the discharge port of said insert and the opening in said canister cap.

Claim 11

(b) a canister for removable insertion into said housing comprising (1) a container having an open top which holds a fog-producing material and which is constructed of a material which will transfer heat from a heat source to said fog-producing material; (2) an insert secured in said container to close said open top and having a dome with a discharge port to allow the release of a fog; and (3) a cap attached to said container for covering said container having an opening overlying said discharge port of said insert to allow the release of a fog and having at least one lug extending from said cap for activating said electric fogger; (c) a means on said housing for receiving and replaceably holding said canister in said housing; (d) an electrical heating means in said housing for heating said canister in said housing; (e) an electrical timing means within said housing which controls said heating means whereby said heating means is operated for a predetermined period of time; and (f) an electrical switch means constructed and arranged with said timing means and said heating means for activating said timing means and said heating means, said switch means being activated by one of said lugs on said canister upon insertion and rotation of said canister in said receiving and holding means of said housing; thereby heating said canister, the heat being transferred to said fog-producing material to produce a fog which is released to an environment of use through the discharge port of said insert and the opening in said canister cap.

Claim 12

An electric fogging apparatus comprising: (a) a housing consisting of a base member and a top member; (b) a disposable canister for removable insertion into said housing comprising (1) a container having an open top which holds a fog-producing material and which is constructed of a material which will transfer heat from a heat source to said fog-producing material; (2) an insert secured in said container to close said open top and having a dome with a discharge port to allow the release of a fog; (3) a closure means attached to said insert to close said discharge port until a fog is to be released; and (4) a cap attached to said container for covering said container having an opening overlying said discharge port of said insert to allow the release of a fog and having at least one lug extending from said cap for activating said electric fogger; (c) an opening in said top member of said housing for receiving and replaceably holding said disposable canister said opening being bounded by at least one flange, said flange having at least one space for receipt of a lug from said canister; (d) an electric hot plate secured in the base of said housing under said opening in said housing for supporting and heating said disposable canister; (e) a printed circuit board located in said housing including (1) an electrical switch comprising a leaf spring and a contact whereby said leaf spring contacts the contact to close the electrical circuit allowing the flow of electricity to said hot plate; and (2) a timing means whereby said hot plate is operated for a predetermined period of time; and (f) a pivoting cam in said housing constructed and arranged to engage simultaneously one of said lugs on said canister upon insertion and rotation of said canister in said opening of said housing and said electrical switch means to activate said hot plate; thereby heating said canister, the heat being transferred to said fog-producing material to produce a fog which is released to an environment of use through the discharge port of said insert and the opening in said canister cap.

Claim 13

An electric fogging apparatus comprising: (a) a housing consisting of a base member and a top member; (b) a disposable canister for removable insertion into said housing comprising (1) a container having an open top which holds a fog-producing material and which is constructed of a material which will transfer heat from a heat source to said fog-producing material; (2) an insert secured in said container to close said open top and having a dome with a discharge port to allow the release of a fog; (3) a closure means attached to said insert to close said discharge port until a fog is to be released; and (4) a cap attached to said container for covering said container having an opening overlying said discharge port of said insert to allow the release of a fog and having at least one lug extending from said cap for activating said electric fogger; (c) an opening in said top member of said housing for receiving and replaceably holding said disposable canister said opening being bounded by at least one flange, said flange having at least one space for receipt of a lug from said canister; (d) an electric hot plate secured in the base of said housing under said opening in said housing for supporting and heating said disposable canister; (e) a printed circuit board located in said housing including (1) an electrical switch comprising a leaf spring and a contact whereby said leaf spring contacts the contact to close the electrical circuit allowing the flow of electricity to said hot plate; and (2) a timing means whereby said hot plate is operated for a predetermined period of time; and (f) a pivoting cam in said housing constructed and arranged to engage simultaneously one of said lugs on said canister upon insertion and rotation of said canister in said opening of said housing and said electrical switch means to activate said hot plate; thereby heating said canister, the heat being transferred to said fog-producing material to produce a fog which is released to an environment of use through the discharge port of said insert and the opening in said canister cap.
