Claim 7

A container closing device comprising: a. an elongated housing having a base portion with a compartment therein and a cover member closing the compartment, said cover member having an elongated opening therein; b. a lid having one edge hingedly mounted on said housing and movable between a position overlying said cover member and a position substantially normal to said cover member; c. an elongated material engaging member mounted on said cover member and positioned within the compartment and having a first portion having an edge engageable by material to be heat sealed and a second portion having a surface engageable by material to be heat sealed, said material engaging member being mounted for movement between a position having the edge in alignment with the opening in said cover member and a position having the surface in alignment with the opening in said cover member; d. an elongated press member mounted on said lid and positioned thereon to be in overlying relation with said material engaging member when said lid is in overlying relation with said cover member; e. means on said cover member for positioning a portion of said material to be heat sealed in overlying relation with the opening in said cover member; and f. a heating element electrically connected to a source of electrical power and positioned in engagement with said material engaging member and adapted to heat said material engaging member to a temperature within a selected range of temperatures.

Claim 8

A container closing device comprising: a. an elongated housing having a base portion with a compartment therein and a cover member closing the compartment, said cover member having an elongated opening therein; b. a lid having one edge hingedly mounted on said housing and movable between a position overlying said cover member and a position substantially normal to said cover member; c. an elongated material engaging member mounted on said cover member and positioned within the compartment and having a first portion having an edge engageable by material to be heat sealed and a second portion having a surface engageable by material to be heat sealed, said material engaging member being mounted for movement between a position having the edge in alignment with the opening in said cover member and a position having the surface in alignment with the opening in said cover member; d. an elongated press member mounted on said lid and positioned thereon to be in overlying relation with said material engaging member when said lid is in overlying relation with said cover member; e. means on said cover member for positioning a portion of said material to be heat sealed in overlying relation with the opening in said cover member; and f. a heating element electrically connected to a source of electrical power and positioned in engagement with said material engaging member and adapted to heat said material engaging member to a temperature within a selected range of temperatures.

Claim 9

A heat sealing device as set forth in claim 6 wherein: a. said material engaging member has a generally U-shaped portion having a pair of spaced flanges extending from a web portion; b. said surface of the second portion of said material engaging member is positioned on the web portion of said U-shaped portion; c. said first portion of said material engaging member comprises a flange extending from one of said flanges of said U-shaped portion and generally normal thereto.

Claim 10

A heat sealing device as set forth in claim 6 wherein: a. said surface of the second portion of said material engaging member is formed of a release material to thereby substantially eliminate adherence between the material to be heat sealed and said surface of said second portion of said material engaging member; and b. said press member has a surface formed of a release material to thereby substantially eliminate adherence between said press member and the material to be heat sealed.

Claim 11

A heat sealing device, as set forth in claim 8 wherein: a. said release material forming said surface of the second portion is a silicone rubber; and b. said release material forming the surface of said press member is a glass fabric having a teflon coating. 10.
