BACKGROUND OF THE INVENTION Field of the InventionThe present disclosure relates to tamper evident containers.
The written disclosure herein describes illustrative embodiments that are non-limiting and non-exhaustive. Reference is made to certain of such illustrative embodiments that are depicted in the figures, in which:
The embodiments disclosed herein relate to containers that may be used, for example, in the food industry. In particular, certain embodiments disclosed herein relate to tamper evident containers that may be used for storing and/or transporting food products. It will be readily understood that the components of the present disclosure, as generally described and illustrated in the drawings herein, could be arranged and designed in a wide variety of different configurations. Thus, the following more detailed description of the embodiments is not intended to limit the scope of the disclosure, but is merely representative of possible embodiments of the disclosure. While various aspects of certain embodiments are presented in drawings, the drawings are not necessarily drawn to scale.
Certain embodiments can advantageously be supplied to an intermediary user in an open preloading configuration (e.g.,
As shown in
The base 110 may further include a sidewall 114 that extends upwardly from the bottom end 112. The bottom end 112 and the sidewall 114 can cooperate to define a cavity 116. The base 110 may be generally bowl-shaped, although other shapes and configurations are possible. In some embodiments, the sidewall 114 may extend upwardly in a substantially vertical manner that it is substantially perpendicular to the bottom end 112. In other embodiments, the sidewall 114 may extend upwardly and may be angled radially outwardly. For example, the sidewall 114 may extend upwardly in a radially outward direction at an angle of about 5 degrees to about 10 degrees, or from about 5 degrees to about 15 degrees. In yet other embodiments, the sidewall 114 may extent upwardly in a curved or arcuate manner. Accordingly, as can be appreciated, the sidewall 114 may extend upwardly in a variety of ways depending on the desired shape and characteristics of the container 100.
The sidewall 114 may be substantially uniform or flat, or it may comprise one or more features for reinforcement, grip assistance, etc. For example, in the illustrated embodiment, the sidewall 114 comprises a plurality of substantially vertically oriented ribs 115. The ribs 115 may provide the base 110 with strength and/or may augment its rigidity.
The base 110 of the container 100 may further comprise a base connection interface 118 disposed at an upper end of the sidewall 114. The base connection interface 118 may be configured to interact with portion the lid 130 so as to close the container 100, as further discussed below. In some embodiments, the base connection interface 118 may extend about at least a majority of a periphery of the sidewall 114. For example, in various embodiments, the base connection interface 118 may extend about at least ½, ⅔, or ¾ of a total periphery of the upper end of the sidewall 114. In further embodiments, the base connection interface 118 may extend about an entirety of the periphery of the sidewall 114. In yet other embodiments, the base connection interface 118 may extend around a smaller portion of the sidewall 114.
A base flange 120 can extend outwardly relative to the base connection interface 118. The base flange 120 may be directly connected to or otherwise coupled with an upper end of the base connection interface 118. Accordingly, the base flange 120 may be configured such that it is at a higher position than is base connection interface 118, as compared with to the bottom end 112. In the illustrated embodiment, the base flange 120 is positioned at an upper end of the base connection interface 118, and the base flange 120 extends radially outwardly in a horizontal direction from the base connection interface 118 (see also
At least a portion of the base flange 120 can be flat or planer. For example, in the illustrated embodiment, the base flange 120 defines a plane that is parallel to the plane defined by the bottom end 112. The planar portion of the base flange 120 may extend about at least a majority of the perimeter of the base. In some embodiments, at least a majority of the base flange 120 may be substantially planar. In yet other embodiments, only a portion of the base flange 120 may be substantially planar.
In other embodiments, the base flange 120 may have configurations that are non-planar and/or multi-planar. For example, the base flange 120 may extend upwardly at an angle relative to a horizontal plane (e.g., at an angle no less than about 30, 45, 60, or 75 degrees). Depending on the shape of the container, the base flange 120 may have substantially planar regions, substantially conical regions, and or regions that define other shapes. For example, where the base flange 120 extends upwardly at a constant angle along the periphery of the container 100 at each radial position, and the container is substantially rectangular, the upwardly extending flange 120 may define a different plane along each of the linear regions of the rectangle, and the flange 120 may define substantially conical regions at the corners that connect adjacent planar regions. As another example, where the base flange 120 extends upwardly at a constant angle along the periphery of the container 100 at each radial position, and the container is substantially circular, the flange 120 may define a substantially conical region that extends about at least a majority of the periphery of the base 110. Other arrangements are also contemplated.
The base flange 120 may further comprise a free edge 122 that defines at least a portion of the outermost perimeter of the base 110. In some embodiments, the free edge 122 may extend about at least a majority of the outermost periphery of the sidewall 114. In the illustrated embodiment, for example, the free edge 122 extends about the outermost periphery of the sidewall 114 everywhere other than at the hinged portion 105. In other embodiments, the free edge 122 may extend about the entirety of the outermost periphery of the sidewall 114. The free edge 122 of the base flange 120 may therefore extend about at least a majority, up to and including the entirety, of the outermost perimeter of the base 110.
With continued reference to
The lid 130 can include a lid connection interface 132 that is configured to interact with a complementary or otherwise cooperative portion of the base 110. For example, the lid connection interface 132 may be configured to selectively couple with the base connection interface 118. In some embodiments, the connection interfaces 132, 118 are complementary in shape (see
The lid connection interface 132 may extend about at least a majority of the periphery of the lid 130. In some embodiments, the lid connection interface 132 may also extend about the entire periphery of the lid 130. When the container 100 is in a closed configuration, the lid 130 and the base 110 may be coupled or otherwise attached such that the cavity 116 defined by the base 110 is closed by the lid 130, or stated otherwise, is enclosed by the lid 130 and the base 110.
The lid 130 can include a lid flange 134 that may extend outwardly relative to the lid connection interface 132. In some embodiments, the lid flange 134 may be directly connected to an end of the lid connection interface 132. The lid flange 134 may have a free edge 136 that may define at least a portion of the outermost perimeter of the lid 130. In some embodiments, the lid free edge 136 may extend about at least a majority of, up to and including the entirety of, the outermost perimeter of the lid 130.
With continued reference to
In other embodiments, the lid flange 134 may have configurations that are non-planar and/or multi-planar. For example, the lid flange 134 may extend upwardly at an angle relative to a horizontal plane (e.g., at an angle no less than about 30, 45, 60, or 75 degrees) when the container 100 is in the closed pre-use configuration shown in
With continued reference to
The lid flange 134 may have a weakened region that borders a portion of the tab 140. This weakened region 134 may allow for controlled separation (e.g., tearing) of a portion of the tab 140 from the lid flange 134. The weakened region 134 may further act as an indicator for demonstrating that the container 100 has been opened or otherwise tampered with, as discussed further below.
As further shown in
Separation of the tab 140 along the weakened region 142 can indicate whether the container has been opened or otherwise tampered with. For example, separation of the tab 140 along the weakened region 142 may indicate that the lid 130 has been uncoupled from the base 110 to transition out of the closed pre-use configuration, as discussed further below with respect to
An arrangement such as depicted in
In some embodiments, the container 100 can include further features to aid the user in readily using the tab 140. For example, the tab 140 may include any suitable indicia for indicating that the container 100 is opened by pulling on the tab 140. The tab 140 may include writing, coloring, or other instructive markings. In the embodiment illustrated in
In some embodiments, such as that illustrated in
As shown in
In some embodiments, pulling on the tab 140 into the position shown in
After the container 100 has been transitioned to the open post-use configuration, it may be closed again, and thereby transitioned to a closed post-use configuration. For example, the connection interfaces 118, 132 and the base 110 and the lid 130, respectively, can be configured to repeatedly engage with each other and disengage from each other. When in the closed post-use configuration, the tab 140 may remain in a displaced state. For example, in some embodiments, the container 100 may look substantially like what is depicted in
Lid tab includes legs 148a and 148b with terminal portions 149a and 149b that extend to stops, as described above. Terminal portions 149a and 149b become elongated when lid 130 is pivoted to open container 100. Terminal portions 149a and 149b extend beyond their elastic limit and yet remain sufficient structural integrity to allow lid tab 140 to be grasped and overcome the interaction of the lip seal. Once the line of weakness or perforation 143 has been opened, an opening 141 is formed and the legs 148a and 148b form a stirrup-like configuration. In one embodiment it takes about 2 lbs to deform terminal portions 149a and 149b and about 5 lbs to open the container. One of the advantages of this configuration is that the deformation and opening occur in the same movement. Also, any jagged edges perforation 143 are not exposed.
Any methods disclosed herein comprise one or more steps or actions for performing the described method. The method steps and/or actions may be interchanged with one another. In other words, unless a specific order of steps or actions is required for proper operation of the embodiment, the order and/or use of specific steps and/or actions may be modified.
