## Background
FIELD OF TECHNOLOGY
The present disclosure pertains to a container with a tearable lid, and a method of manufacturing thereof.
BACKGROUND
Plastic containers are used throughout the food industry to hold various kinds of perishable foods. The containers usually contain a base that contains the food and a lid that closes the container in a sealed manner. This allows the food to maintain a certain level of freshness and prevent or limit the amount of germs and/or bacteria that may enter the container and therefore contaminate the food. With many containers, the lid and base are separate components that allow for the container to be freely opened and closed. With such containers, however, it may be difficult for a consumer to discern if the container has been opened after the food has been packaged therein, and therefore may be contaminated with germs, prior to purchasing the particular food packaged in the container.
Accordingly, an improved, container with a tearable lid, and a method of manufacturing thereof, is presented that allows for a consumer to easily identify if the container has been tampered with by another.

DETAILED DESCRIPTION
To provide a consumer with an easily identifiable indicator of tampering of a container, the container may include a base having a bottom and a plurality of side walls extending upward from the bottom to define an interior therebetween, and a lid configured to engage with the base in a closed configuration to enclose the interior. The container may also include a connecting portion by which the base and the lid may be connected in an initial state. The base may have an extension portion extending laterally outward from a lateral side of the base and connected to the connecting portion via a folding line about which the connecting portion and the lid may be rotatable with respect to the base between the closed configuration and an open configuration. The lid may also have an extension portion extending laterally outward from a lateral side of the lid and connected to the connecting portion via a tear line. The tear line may be weakened such that the lid may be separable from the connecting portion and the base at the tear line while the connecting portion may remain intact with the base.
An exemplary method for manufacturing a container with indicators of tampering, such as the container described above, may include forming from a single sheet of a plastic material a base and a lid connected to each other via a connecting portion. The base may have a bottom and a plurality of side walls extending upward from the bottom to define an interior therebetween, and an extending portion extending laterally outward from a lateral side of the base and connected to the connecting portion via a first line. The lid may have an extending portion extending laterally outward from a lateral side of the lid and connected to the connecting portion via a second line. The method may then include folding the plastic material along the first line such that the connecting portion and the lid may be rotatable about the first line with respect to the base between a closed configuration, in which the lid is engaged with the base to enclose the interior, and an open configuration. The method may further include weakening the plastic material along the first line such that the lid is separable from the connecting portion and the base at the second line while the connecting portion remains intact with the extension portion of the base.
Referring now to the figures, FIGS. 1-4 illustrate an exemplary container 10 used to sealably hold food or other items while providing a means for detecting any tampering with the container 10. The container 10 generally may include a base 12 and a lid 14. The base 12 and the lid 14 may be formed from a single sheet of plastic such that they are connected in an initial state. The base 12 generally may include a bottom 16 and a plurality of side walls 18 extending upward from the bottom 16. The bottom 16 and the side walls 18 may define an interior space 20 in which the food or other items may be contained. The base 12 and the lid 14 generally may be configured to engage with each other in a closed configuration to enclose the interior space 20. The lid 14 may include a top 15 that substantially covers the interior space 20.
In the initial state, the base 12 and the lid 14 may be connected to each other by a connecting portion 22. To achieve this connection, the base 12 may include an extension portion 24 extending laterally outward from a lateral side 26 of the base 12. The lid 14 may similarly include an extension portion 28 extending laterally outward from a lateral side 30 of the lid 14 that corresponds to the lateral side 26 of the base 12. The extension portion 24 of the base 12 may be connected to the connecting portion 22 via a folding line 32. The base 12 and the lid 14 generally may be rotatable with respect to each other about the folding line 32 to move from an open configuration, as illustrated in FIGS. 1 and 2, to the closed configuration, as illustrated in FIGS. 3 and 4. The extension portion 28 of the lid 12 may be connected to the connecting portion 22 via a tear line 34. The tear line 34 generally may be a line at which the material of the container 10 is weakened such that the base 12 and the lid 14 may be physically separated from each other along the tear line 34, for example, via tearing, as explained in more detail hereinafter, while the connecting portion 22 remains intact with the extension portion 24 of the base 12.
The extension portions 24 and 28 may extend substantially a same distance laterally outward such that the connecting portion 22 may be oriented substantially vertically in the closed configuration, as seen in FIGS. 3 and 4. The extension portions 24 and 28 may also have substantially a same longitudinal length, while the connecting portion 22 generally may have a shorter longitudinal length than the extension portions 24 and 28 such that longitudinal ends of the extension portions 24 and 28 may extend beyond the connecting portion 22 in the longitudinal direction. The connecting portion 22 may also be substantially centered with respect to the extension portions 24 and 28 in the longitudinal direction. Such a configuration may allow for opposing ends of each of the extension portions 24 and 28 that extend beyond the connecting portion 22 to be equally sized, such that any one of these ends may be sufficiently gripped in the closed configuration.
To ease the gripping of these ends, the extension portions 24 and 28 may further include gripping portions 36 at the longitudinal ends thereof. The gripping portions 24 and 28 may be areas at which the material of the container 12 is roughened to create friction between a consumer's fingers. In addition or alternatively, the gripping portions 36 may include a series of bumps, corrugations, or the like to create an uneven surface for improved grippability. The gripping portions 36 may be located on a top surface and/or a bottom surface of the extension portions 24 and 28. While the figures illustrate both of the extension portions 24 and 28 each having gripping portions 36 at both longitudinal ends, it should be appreciated that the gripping portions 36 may be located at just one of the longitudinal ends, for example, if the connecting portion 22 is off center with respect to the extension portions 24 and 28 in the longitudinal direction such that only the one longitudinal end extends beyond the connecting portion 22 in the longitudinal direction.
In alternative embodiments not shown, there may be more than one connecting portion 22 that may be equally spaced apart in the longitudinal direction from a center of the extension portions 24 and 28. This may create one or more intermediate portions of the extension portions 24 and 28 located between the connecting portions 22 in the longitudinal direction. The intermediate portion(s) may be used to grip the extension portions 24 and 28 in addition to or in lieu of the longitudinal ends, and may further include gripping portions 36 to improve grippability, as described above.
In the initial state and closed configuration, the container 10 generally cannot be opened without separation of the base 12 and the lid 14. Thus, a consumer can simply look at the container 10 to see if the base 12 and the lid 14 are still connected by the connecting portion 22 to determine if the container 10 has been preemptively opened or otherwise tampered with. An easily identifiable indicator of the connection between the base 12 and the lid 14 may be the substantially vertical orientation of the connecting portion 22, as explained above and illustrated in FIGS. 3 and 4. If the connecting portion 22 is not vertically oriented, it is clear that the base 12 and the lid 14 are no longer connected.
To separate the base 12 and the lid 14 when the container 10 is in the initial state and closed configuration such that the contents stored therein can be accessed, the consumer 10 may grip a portion of the extension portion 24 of the base 12 and a portion of the extension portion 28 of the lid 14, for example, the longitudinal ends of the extension portions 24 and 28, and apply at least an upward force on the extension portion 28 of the lid 14. Such an upward force may cause the lid 14 to separate or from the connecting portion 22 at the tear line 24, which as explained above may be weakened to facilitate the separation. The connecting portion 22 generally may stay intact with the base 12 at the extension portion 24. The base 12 and the lid 14 may then be freely opened and closed.
Referring now to FIG. 5, to maintain the container 10 in the closed configuration, the lid 14 may also include a rounded or bubble portion 17 extending downward from and arranged around at least a portion of a periphery of the top 15, and a lid sealing wall 19 extending upward from the bubble portion 17. The base 12 may include a first shoulder 21 extending outward from the side walls 18 in a direction away from the interior space 20, and a base sealing wall 23 extending upward from the first shoulder 21 to form a pocket 25 configured to receive the bubble portion 17. The rounded shape of the bubble portion 17 may allow for compression of the lid 14 in a downward direction to absorb downward forces applied to the top 15 of the lid.
When the bubble portion 17 is received in the pocket 25, the lid sealing wall 19 and the base sealing wall 21 may engage with each other via a compression fit to maintain the container 10 in the closed configuration. To further the compression fit, the base sealing wall 23 and the first shoulder 21 may form an acute angle. However, it should be appreciated that the base sealing wall 23 and the first shoulder 21 may be oriented at a right angle or an obtuse angle.
The base 12 may further include a second shoulder 27 extending outward from the base sealing wall 23, and the lid 14 may further include a lip 29 extending outward from the lid sealing wall 19 and that engages with the second shoulder 27 to further maintain the container 10 in the closed configuration. The base 12 may also include a curb 31 extending upward from the second shoulder 27 such that the lip 29 is not grippable to open the container 10, for example, without separating the base 14 and the lid 12 at the tear line 34.
Referring back to FIGS. 1-4, the lid 14 may further include a plurality of stacking ridges 38 extending upward from the top 15 of the lid 14 and arranged to define an area between which the base 12 of another container 10 may securely fit. The stacking ridges 38 may be configured to engage with the side walls 18 of the base of the other container 10 such that multiple containers 101, 102 are stackable one on top of another in a secured manner, as illustrated in FIG. 6.
Referring now to FIG. 7, an exemplary method 100 for manufacturing a container with a tearable lid, such as the container 10, for providing an indication of tampering is illustrated. While method 100 is described with respect to container 10, it should be appreciated that method 100 may apply to any container in which the steps of method 100 are applicable. Method 100 may begin at step 102 in which a base 12 and a lid 14 are formed from a single sheet of a plastic material with a connecting portion therein. As explained above, the base 14 may have a bottom 16 and a plurality of side walls 18 extending upward from the bottom 16 to define an interior space 20 therebetween, and an extension portion 24 extending laterally outward from a lateral side 26 of the base 12. The extension portion 24 may be connected to the connecting portion 22 via a first line 32. The lid 14 may similarly have an extension portion 28 extending laterally outward from a lateral side 30 of the lid 14. The extension portion 28 may be connected to the connecting portion 22 via a second line 34. The forming of the base 12, lid 14, and connecting portion 22 may be achieved by any process.
After step 102, method 100 may proceed to step 104 at which the first line 32 may be bent or folded such that the connecting portion 22 and the lid 14 are rotatable with respect to the base 12.
After step 104, method 100 may proceed to step 106 at which the second line 34 may be weakened such that the lid 14 may be separable from the connecting portion 22 and the base 12 at the second line 34, for example, via tearing. The weakening may be done by any process, including, but not limited to, perforating the material along the second line 34.
Method 100 may end after step 106.
