Packaging machine cup and lid sealing assembly and cup sealing assembly

A cup sealing assembly comprising:

• a lower housing member having a lower wall having a lower end and an upper end, with a central wall extending across the upper end of the lower wall defining a cavity, at least one cooling slot defined in the lower wall providing ingress into the cavity;
• an upper housing member having an upper wall and an upper transverse wall, the upper wall having a lower end positioned on the central wall, defining an upper cavity, at least one pair of cooling slots defined in the upper wall the pair of cooling slots being spaced apart from each other in a vertical orientation;
• a lower housing plate positioned at the lower end of the lower housing member;
• a heater plate having an upper surface and a lower surface, with an outer rim extending from the lower surface;
• a heating element comprising a lower coil sandwiched between the upper surface of the heater plate and the lower surface of the lower housing plate;
• and
• at least one heater plate fastener coupling the lower housing member to the heater plate, and extending through the lower housing plate.

A packaging machine cup and lid sealing assembly comprising:

• a housing;
• a plurality of cup sealing assemblies, each of the plurality of cup sealing assemblies being attached to the housing through a coupling, the coupling comprising at least one fastener, with a spring biasing the cup sealing assembly relative to the housing and the at least one fastener, at least one of the plurality of cup sealing assemblies comprising:
• a lower housing member having a lower wall having a lower end and an upper end, with a central wall extending across the upper end of the lower wall defining a cavity, at least one cooling slot defined in the lower wall providing ingress into the cavity;
• an upper housing member having an upper wall and an upper transverse wall, the upper wall having a lower end positioned on the central wall, defining an upper cavity, at least one pair of cooling slots defined in the upper wall the pair of cooling slots being spaced apart from each other in a vertical orientation;
• a lower housing plate positioned at the lower end of the lower housing member;
• a heater plate having an upper surface and a lower surface, with an outer rim extending from the lower surface;
• a heating element comprising a lower coil sandwiched between the upper surface of the heater plate and the lower surface of the lower housing plate;
• and
• at least one heater plate fastener coupling the lower housing member to the heater plate, and extending through the lower housing plate.
