Definitions

  • This invention relates generally to plastic food containers.
  • the invention is more specifically related to resealable plastic food containers having tamper evident sealing mechanisms.
  • the typical food container of the prior art consists of a solid color (typically black) base and a clear lid.
  • the clear lid of the prior art plastic food container allows visible inspection of the container contents.
  • the lid and base of the prior art plastic food container may be separate articles or may be hingedly attached to each other.
  • the food container, once sealed it is desirable that the food container, once sealed, not be capable of being initially opened without visible indication of the container having been opened. Accordingly, it is known in the prior art to manufacture food containers having tamper evident sealing mechanisms.
  • the prior art plastic food container has utilized a band of tape around the sealed container or a sticker label extending across a portion of the contact area of lid and base rims of the sealed container for tamper evidence. Opening the container (i.e., separating the lid from the base) requires rupturing the band or sticker label. The ruptured band or label provides evidence of tampering or initial opening of the sealed container.
  • a problem with this method of tamper evidence is that the container requires articles apart from the container itself to effect the tamper evidence.
  • the additional step of applying the band or label is required after sealing the container. ⁇ 0004]
  • container manufacturers have designed containers having integral tamper evident features.
  • these containers consist of a lid that is hingedly attached to a base.
  • the lid seals to the base by superposing the rim of the lid upon the rim of the base.
  • the lid and base each have interlocking elements respectively located on or near the lid rim and base rim.
  • the interlocking element of the lid or base is conventionally located on a tab or flange extending from the rim of the lid or base. Either or both of the tabs are attached to their respective rims by a frangible section of plastic.
  • the frangible section of one or both tabs In order to open the sealed container, the frangible section of one or both tabs must be ruptured so as to release the tab or tabs from the container. Because the interlocking sealing elements are located on the tabs, rupturing one or more tabs from the container, disables the locking mechanism. The ruptured tab provides evidence of the container having been opened.
  • the lid and base can be partially pried open by inserting a thin object underneath an exposed rim edge at a point on the container distal from the tamper indicator.
  • a thin object underneath an exposed rim edge at a point on the container distal from the tamper indicator.
  • the present invention satisfies the needs in the art and provides an aesthetically appealing food container that is easy to use and that is both tamper resistant and tamper evident.
  • the present invention food container comprises a plastic food container having a lid adapted for sealing arrangement with a base.
  • the lid has a perimeter flange that includes at least one localized, integrally formed flange tab.
  • the base has a floor and a rim and a sidewall extending between the floor and the rim.
  • the rim of the base has an undercut formation. The undercut formation is adapted to receive the perimeter flange and flange tab when the lid and base are in the sealed arrangement.
  • the flange tab includes an undercut release mechanism, which allows a portion of the flange tab to be grasped and pulled. Pulling the flange tab extracts its edge from the undercut formation of the base rim.
  • the undercut release mechanism is formed such that the pulling force necessary to extract the flange tab from the undercut formation deforms the flange tab. The deformed flange tab provides visible evidence that the sealed container has been initially opened.
  • the container comprises a lid adapted for sealing arrangement with a base.
  • the lid comprises an upper portion, a descending surface and a rim that engages the rim of the base.
  • the upper portion of the lid comprises one or more horizontal and vertical surfaces that extend to form the descending surface.
  • the descending surface extends to form a horizontal transition segment.
  • This segment descends to form a multi-segment rim structure.
  • This rim structure includes a generally vertically oriented inner wall.
  • the inner wall curves outwardly (peripherally) to form a peripherally projecting segment that defines the lowermost point of the lid.
  • the respective rims of the lid and base each have a complementary engaging multi-surface (segment) structure.
  • the lid rim structure includes a vertical sealing segment that extends upwardly from the peripherally projecting segment to a perimeter flange.
  • the lid vertical sealing segment is angled inwardly (towards the interior of container).
  • the base comprises a floor and a sidewall, the sidewall extending between the floor and the rim.
  • the base rim structure contains an undercut formation that is adapted to engage the perimeter flange of the lid.
  • the method by which the lid is retained by the undercut formation of the base rim provides defense against access to the sealed container contents via prying of the lid from the base.
  • the perimeter flange of the lid includes at least one integrally formed flange tab, which when the container is sealed is also protectively captured by the undercut structure of the base rim.
  • This flange tab is generally planar and incorporates an undercut release mechanism that allows a user to extract the engaged flange tab from the base rim.
  • the undercut release mechanism is a releasable grip tab integrally formed in the flange tab via a frangible outline of perforations or scoring. The perforations or scoring define the shape of the grip tab.
  • a three-step process is required to open the container.
  • a separation force must be applied to the grip tab to cause rupture of its frangible outline and the grip tab to pop up out of the flange tab to a position it can be grasped by a thumb and forefinger.
  • the now released grip tab is pulled toward the user, causing the engaged flange tab to roll inwardly down and be released by the base rim structure.
  • the lid can be removed from the base by pulling the flange tab up and inwardly toward the center of the container. This last pulling action causes the disengagement of the lid perimeter flange from the base rim.
  • the undercut release mechanism is further adapted to deform when tab-releasing forces are applied to it. This deformation provides visible indication that the container has been initially opened.
  • the flange tab includes a fracture line that prefereably emanates from the frangible outline defining the grip tab. This fracture line is designed to rupture when pulling action is imparted to the grip tab to extract the flange tab from the base rim's undercut formation. The rupturing of this fracture line provides visible indication that the grip tab has been employed to open the container.
  • the undercut release mechanism is designed such that once the fracture line ruptures, the application of pulling force to the grip tab or flange tab will cause further visible deformation of the flange tab from its original planar shape. This deformation provides additional indicia that the lid retaining mechanism of the container has been compromised and that the lid has been subjected to opening forces.

  • this undercut release mechanism comprises a grip tab 61 integrally formed in flange tab 60 by means of frangible outline 62.
  • Frangible outline 62 is adapted to rupture when finger pressure is applied to one or more pressing areas 63 of grip tab 61 such that grip tab 61 is caused to move in a perpendicular direction relative to the surface of flange tab 60.
  • pressing areas 63 of grip tab 61 are raised and platform extension 80 includes cavity 81. Inclusion of these features enhances the vertical flexing and movement of grip tab 61 relative to the horizontal surface of flange tab 60 when pressure is applied to grip tab 61.
  • pressing area 63 is provided with space for downward travel.
  • including cavity 81 in platform 80 enhances the degree of downward travel of pressing areas 63.
  • flange tab 60 is in superpositional contact with platform extension 80.
  • the undercut release mechanism is deployed as follows. Pressing vertically downward upon pressing areas 63 causes the inner portion of grip tab 61 to descend past the surface of flange tab 60 and on into cavity 81. When pressing area 63 is caused to move downward, frangible outline 62 initially ruptures near the pressing area. This initial rupturing allows grip tab 61 to descend further relative to flange tab 60. With continued downward pressure on pressing area 63, pop-up tip 65 of grip tab 61 is pulled away from flange tab 60 until it completely separates from flange tab 60 along frangible outline 62.
  • grip tab 61 includes scored line 67, which serves as a flex point when downward pressure is applied to pressing area 63.
  • cavity 81 is preferably sized and positioned on platform 80 such that scored line 67 will be situated above distal edge 75 of cavity 80 when the container is sealed. Distal edge 75 thus acts as a fulcrum against grip tab 61 when grip tab 61 is depressed.
  • grip tab 61 When downward pressure is applied to pressing area 63 of grip tab 61, grip tab 61 will bend focally along score line 67, enhancing the pop-up action of pop-up tip 65. Should the application of pressing force upon grip tab 61 cause it to descend below flange tab 60 or not result in pop-up tip 65 of grip tab 61 reaching a point of graspability, then grip tab 61 can be pulled out from flange tab 60 and into a graspable position by applying pull-back force against knurlments 64.
  • grip tab 61 As shown in FIG. 12 once grip tab 61 is in a graspable position it is deployed and can be used to extract flange tab 60 from rim 30. In this respect, deployed grip tab 61 is grasped and pulled toward the user. Pulling on grip tab 61 in this fashion causes flange tab 60 to lift and the edge 24 of flange tab 60 to point downward and move inward along platform 80 (away from the undercut formation of base rim structure 30) and towards the center of container 10. Once edge 24 of flange tab 60 is moved inwardly past top vertical segment 38 of the undercut formation of base rim 30, flange tab 60 can be pulled out from, and is released by, the undercut formation of base rim 30.
  • flange tab 60 is released by base rim 30, the user can pull or push the flange tab 60 away from base 25 causing adjoining sections of peripheral flange 22 to be pulled out from the undercut formation of rim 30. Once approximately half of the lid's flange has been pulled out from the undercut structure of the base rim, lid 11 will openly separate from base 25.
  • the undercut release mechanism of the present invention container is adapted to distinguish between user actions that merely cause the initial partial separation of grip tab 61 from flange tab 60 and actions that indicate opening of the container.
  • flange tab 60 includes one or more further fracture lines 69 preferably emanating from frangible outline 62 and leading toward edge 24. Fracture line 69 can be formed via perforations, scoring or thinning of container, material. Fracture line 69 is formed on flange tab 60 such that the force required to pull edge 24 of flange tab 60 out from the undercut formation of rim structure 30 also causes flange tab 60 to further visibly rupture along score line 69.
  • fracture line 69 provides evidence that the undercut release mechanism has been utilized and the container has been opened. Additionally, once score line 69 ruptures, the subsequent application of pull force to grip tab 61 or flange tab 60 will cause flange tab 60 to twist and deform from its initial planar shape. An example of this deformation is shown in FIG. 13. Such resulting deformation provides additional evidence to the user that the container has actually been opened. By locating, extending or patterning fracture line 69 the resulting deformation to grip tab 61 or flange tab 60 can be made more prominent. For example, fracture line 69 can be shaped in accordance with FIGS. 14a-14d in furtherance of enhancing tamper evidence. As shown in these figures, fracture line 69 can curve away from frangible outline 62 or can be made as an extension of frangible outline 62.
  • FIG. 15 depicts a simpler grip tab 61 construct designed to be deployed via the application of upwardly directed finger pressure through hole 83 in platform 80.
  • the undercut release mechanism could be a separate element mechanically attached to, as opposed to integrally formed in, flange tab 60.
  • a container constructed in accordance with the present invention can be manufactured in a variety of shapes and sizes, and is preferably formed of resins or plastic materials including, but not limited to, polyethylene, polypropylene, polyvinyl chloride or polyethylene terephthalate ("PET").
  • PET polyethylene terephthalate
  • the container lid and base can be transparent or translucent, and may be colored in either instance.
  • the container can be provided with vents to promote the flow of air or steam in or out of the container. Further, the container can be of any shape, including round or polygonal.
  • the rim structures of the container may be adapted to include a hinge such that the lid and base are connected to each other in a clamshell configuration.

Abstract

L'invention porte sur un contenant alimentaire en matière plastique, qui comprend un couvercle adapté pour un agencement de scellement étanche avec une base. Le rebord de la base comporte une formation d'entaille, adaptée pour recevoir la bride périphérique et la patte de bride du couvercle lorsque le couvercle et la base sont dans la configuration de scellement étanche. La patte de bride comprend un mécanisme de libération d'entaille qui permet à un utilisateur de saisir une partie de la patte de bride et d'ouvrir initialement un contenant scellé de façon étanche par l'extraction de la patte de bride à partir de la formation d'entaille, par application d'une force de traction au mécanisme de libération d'entaille. La patte de bride comprend des moyens inviolables qui communiquent une indication visible du fait que le mécanisme de libération d'entaille a été utilisé pour ouvrir initialement le contenant scellé de façon étanche.
