Abstract

Systems, apparatuses, and methods to secure a film to a container are provided. An example sealing device utilizes film from a supply of film to seal a lid onto a container. Various sizes of containers are usable with some example sealing devices. Additional features, such as printing on the film and piercing the film for ventilation and/or insertion of a straw are contemplated. One or more markings along the film may be utilized for confirming that an approved film has been loaded into the sealing device. In response, various components or features of the sealing device may be appropriately enabled or disabled. The one or more markings may also be utilized to convey data to the sealing device regarding the installed film, such as for improved operation thereof.

First claim

The invention claimed is:

1. An apparatus to secure a film to a container, the apparatus comprising:
a body portion to house a roll of film, wherein the body portion comprises:
a drive nip defined by a drive roller and a pinch roller to progress film from the roll of film into a loading zone; and
a film support roller to support the roll of film, wherein the drive roller rotates at a faster speed than the film support roller to cause tension to be applied to the film; and

a sealing portion comprising:
an aperture to receive at least a top portion of the container,

a wall disposed within the sealing portion,
at least one element positioned external to the wall, wherein the at least one element is activated to emanate energy,
a sensor assembly configured to sense when the top portion of the container passes through the aperture so as to activate the at least one element, and
the loading zone, wherein the loading zone is sized to receive a predetermined dimensioned film from the body portion, wherein the top portion of the container is movable within the aperture to secure the predetermined dimensioned film to the top portion of the container by energy from the at least one element through the wall.

2. The apparatus of claim 1 , wherein the wall defines an annular shape with an internal opening that has a width dimension that is at least as large as a width dimension of the aperture.

3. The apparatus of claim 1 , wherein the wall is at least partially transparent or translucent to permit energy emanated from the at least one heating element through the wall.

4. The apparatus of claim 1 , further comprising at least one reflective device disposed within the sealing portion and exterior to the wall, wherein the at least one reflective device reflects at least a portion of energy emanated from the at least one element toward the wall, wherein the at least one reflective device comprises at least one mirror having a first panel, a second panel, and a third panel, wherein the first panel is disposed at a first angle relative to the second panel, and the third panel is disposed at a second angle relative to the second panel.

5. The apparatus of claim 1 , further comprising a fan configured to cool the sealing portion.

6. The apparatus of claim 1 , wherein the body portion comprises a film sensor assembly having a film signal emitter and a film signal sensor to detect markers spaced at predetermined longitudinal distances along the film.

7. The apparatus of claim 1 , wherein the sealing portion further includes a guide support assembly having a ramp and a guide truss, the ramp being capable of receiving the film from the body portion and the guide truss capable of guiding the film to the loading zone.

8. The apparatus of claim 7 , wherein the ramp has a surface extending from a first end to a second end, the surface oriented at an angle of inclination ranging up to 75 degrees, wherein the second end is coupled to a guide surface configured to receive a film from the surface of the ramp.

9. The apparatus of claim 1 , wherein the body portion further comprises a piercer having an actuatable tip to pierce a film.

10. The apparatus of claim 1 , further comprising a printer to print on a film.

11. The apparatus of claim 1 , wherein the sealing portion further comprises a shield plate movable within the sealing portion between a first position and a second position, wherein the top portion of the container is movable within the aperture to move the shield plate to the second position, wherein the sensor is configured to sense that the top portion of the container passes through the aperture.

12. The apparatus of claim 11 , wherein the wall is coupled to the shield plate and movable with the shield plate between the first position and the second position.

13. The apparatus of claim 11 , wherein the wall is fixed within the sealing portion, wherein the shield plate is movable with respect to the wall between the first position and the second position.

14. The apparatus of claim 1 , wherein the body portion comprises a film sensor assembly configured to detect one or more marking patterns along the film, and wherein the apparatus further includes a controller configured to:
determine, based on sensor data from the film sensor assembly, if a detected marking pattern matches an approved marking pattern; and
cause at least one of:
in an instance in which the detected marking pattern matches an approved marking pattern, enabling operation of the apparatus, a feature of the apparatus, or components of the apparatus; or
in an instance in which the detected marking pattern does not match an approved marking pattern, disabling of operation of the apparatus, a feature of the apparatus, or components of the apparatus.

15. The apparatus of claim 1 , wherein the sealing portion further comprises a shield plate fixedly positioned within the sealing portion, wherein the shield plate is spaced apart from and above the aperture, wherein the top portion of the container is movable within the aperture to sandwich the film between the top portion of the container and the shield plate while energy is emanating from the at least one element.

16. The apparatus of claim 1 , wherein the sensor assembly is configured to send a sensor input signal to a controller to cause the controller to prevent advancement of the film into the loading zone.

17. A method of securing a film to a container, the method comprising:
providing an apparatus having a body portion to house a roll of film and a sealing portion,
the body portion comprising:
a drive nip defined by a drive roller and a pinch roller to progress film from the roll of film into a loading zone; and
a film support roller to support the roll of film, wherein the drive roller rotates at a faster speed than the film support roller to cause tension to be applied to the film; and

the sealing portion comprising:
an aperture to receive at least a top portion of the container,
a wall disposed within the sealing portion,
at least one element positioned external to the wall, wherein the at least one element is activated to emanate energy,
a sensor assembly configured to sense when the top portion of the container passes through the aperture so as to activate the at least one element, and
the loading zone, wherein the loading zone is sized to receive a predetermined dimensioned film from the body portion;

sensing the top portion of the container within or above the aperture; and
causing activation of the at least one element to emanate energy though the wall to secure the predetermined dimensioned film to the top portion of the container.

18. The method of claim 17 , further comprising:
printing, by a printer operatively coupled to the body portion, on a length of film; and
piercing, by a piercer having an actuatable tip, the film.

19. The method of claim 17 , further comprising progressing the film into the loading zone.

20. The method of claim 19 , further comprising cutting, by a film cutter operatively coupled to the apparatus between the drive nip and the sealing portion, a length of film to form the predetermined dimensioned film.

21. The method of claim 17 , wherein the sealing portion further comprises a shield plate movable within the sealing portion between a first position and a second position, wherein the top portion of the container is movable within the aperture to move the shield plate.

22. The method of claim 17 , wherein the s
