Abstract

Systems, apparatuses, and methods to seal a container are provided. An apparatus for securing a film to a container includes a body portion to house film and a sealing portion. The sealing portion includes a loading zone to receive a portion of film from the body portion and an aperture to receive a top portion of the container and the portion of the film therethrough to enable positioning within a sealing volume. A plurality of near-infrared light emitting diodes (NIR LEDs) face toward and at least partially surround the top portion of the container when positioned within the sealing volume. A controller is configured to receive sensor input from a sensor indicating that the top portion of the container is within the sealing volume and cause, in response thereto, activation of the plurality of NIR LEDs to secure the portion of the film to the top portion of the container.

First claim

1 . An apparatus for securing a film to a container, the apparatus comprising:
a body portion to house film; a sealing portion comprising:
a sealing volume for receiving a top portion of the container;
a plurality of near-infrared light emitting diodes (NIR LEDs) positioned within the sealing volume so as to at least partially surround the top portion of the container when the top portion of the container is positioned within the sealing volume;
a sensor configured to sense when the top portion of the container is at least partially positioned within the sealing volume; and
a loading zone sized to receive a portion of film from the body portion and position the portion of the film for insertion into the sealing volume with the top portion of the container; and
a controller configured to:
receive sensor input from the sensor indicating that the top portion of the container is at least partially positioned within the sealing volume; and
cause, in response thereto, activation of at least one of the plurality of NIR LEDs to secure the portion of the film to the top portion of the container.

2 . The apparatus of claim 1 , wherein the controller is configured to operate the at least one of the plurality of NIR LEDs for a sealing cycle to secure the portion of film to the top portion of the container, wherein the controller is further configured to adjust energy output of at least one first NIR LED of the plurality of NIR LEDs relative to at least one second NIR LED of the plurality of NIR LEDs during the sealing cycle such that an operation characteristic of the at least one first NIR LED is different than the at least one second NIR LED, wherein the operation characteristic is at least one of an amount of time of operation or a power output.

3 . The apparatus of claim 1 , wherein the portion of the film defines a rectangular shape with four sides and four corners, wherein the top portion of the container defines a circular shape with a perimeter, wherein the four corners of the portion of the film extend past the perimeter of the circular shape of the top portion a greater distance than a center point along each of the four sides such that there is a relative excess of film past the top portion at each of the four corners, wherein the at least one of the plurality of NIR LEDs comprise at least a first set of edge NIR LEDs and a second set of corner NIR LEDs, wherein the first set of edge NIR LEDs is positioned within the sealing volume proximate at least one center point of one side of the portion of the film, wherein the second set of corner NIR LEDs is positioned within the sealing volume proximate at least one corner of the portion of the film,
wherein the controller is configured to operate the at least one of the plurality of NIR LEDs for a sealing cycle to secure the portion of film to the top portion of the container, wherein, during the sealing cycle, the controller is configured to operate the first set of edge NIR LEDs differently than the second set of corner NIR LEDs.

4 . The apparatus of claim 3 , wherein, during the sealing cycle, the controller is configured to operate the second set of corner NIR LEDs to provide a greater amount of energy to the portion of the film than the first set of edge NIR LEDs so as to provide increased energy to the corners of the portion of the film to encourage increased film shrinking at the corners of the portion of the film.

5 . The apparatus of claim 4 , wherein the controller is configured to operate the second set of corner NIR LEDs for a greater amount of time of operation or at a greater power output than the first set of edge NIR LEDs.

6 . The apparatus of claim 4 , wherein the first set of edge NIR LEDs is positioned within the sealing volume proximate each center point of the four sides of the portion of the film, and wherein the second set of corner NIR LEDs is positioned within the sealing volume proximate each corner of the portion of the film.

7 . The apparatus of claim 1 , wherein the top portion of the container defines a plane corresponding to a container lip, wherein the at least one of the plurality of NIR LEDs comprise at least a first set of NIR LEDs and a second set of NIR LEDs, wherein the first set of NIR LEDs is positioned within the sealing volume at a first vertical position corresponding to the plane corresponding to the container lip when the top portion of the container is positioned within the sealing volume, wherein the second set of NIR LEDs is positioned within the sealing volume at a second vertical position, wherein the second vertical position is below the first vertical position,
wherein the controller is configured to operate the plurality of NIR LEDs for a sealing cycle to secure the portion of film to the top portion of the container, wherein, during the sealing cycle, the controller is configured to operate the first set of NIR LEDs differently than the second set of NIR LEDs.

8 . The apparatus of claim 7 , wherein, during the sealing cycle, the controller is configured to operate the second set of NIR LEDs to provide a greater amount of energy to the portion of the film than the first set of NIR LEDs so as to provide increased energy below the container lip to encourage increased film shrinking below the container lip.

9 . The apparatus of claim 8 , wherein the controller is configured to operate the second set of NIR LEDs for a greater amount of time of operation or at a greater power output than the first set of NIR LEDs.

10 . The apparatus of claim 1 , wherein the controller is configured to operate the at least one of the plurality of NIR LEDs according to one of a plurality of operation profiles during a sealing cycle to secure the portion of film to the top portion of the container, wherein the plurality of operation profiles include at least a first operation profile and a second operation profile, wherein an operation characteristic of the first operation profile is different than the second operation profile, wherein the operation characteristic is at least one of an amount of time of operation of one or more of the plurality of NIR LEDs or a power output of the one or more of the plurality of NIR LEDs.

11 . The apparatus of claim 10 further comprising an identification sensor configured to sense identification data associated with the film housed in the body portion, and wherein the controller is configured to determine, based on the identification data, to operate the at least one of the plurality of NIR LEDs according to the first operation profile during the sealing cycle.

12 . The apparatus of claim 10 further comprising a user interface configured to receive user input, wherein the controller is configured to determine, based on the user input, to operate the at least one of the plurality of NIR LEDs according to the first operation profile during the sealing cycle.

13 . The apparatus of claim 1 , wherein the controller is configured to operate the at least one of the plurality of NIR LEDs for a sealing cycle to secure the portion of film to the top portion of the container, wherein the controller is configured to operate the at least one of the plurality of NIR LEDs for less than 2 seconds during the sealing cycle to achieve securement of the portion of the film to the top portion of the container.

14 . The apparatus of claim 1 , wherein the at least one of the plurality of NIR LEDs comprise at least a first set of NIR LEDs and a second set of NIR LEDs, wherein the first set of NIR LEDs is mounted to a first printed circuit board, wherein the second set of NIR LEDs is mounted to a second printed circuit board, wherein the first pr
