Publication number: 20220017270Abstract: A tamper-evident container has a lid with a rim with a bead mating with a groove in a base rim. The rim bead is interrupted by a tab wall which does not engage the base. The lid has a first flange portion which overlies a base flange. The base and lid first flange portions extend outwardly about the same amount. At the tab, a second portion of the lid flange extends substantially outwardly beyond the base flange. The flange second portion is connected to the first portion on both sides of the tab by weakened lines of material which extend cut lines through the tab front wall. The tab second flange portion is engageable to sever the weakened lines of material and pivot the tab upwardly to remove the lid, thus deforming it and evidencing tampering should the lid be replaced on the base. Base vents reduce ballooning when closed.Type: ApplicationFiled: July 16, 2020Publication date: January 20, 2022Applicant: Placon CorporationInventor: Donald E. McCumber

Patent number: 10479580Abstract: A method for separating a package blister from the cards which retain it to promote recycling of the component parts of a package. A thermoformed thermoplastic blister has a product bubble which extends from a peripheral flange to extend through an opening in a front card. The front card is affixed to a back card so as not to adhere to the blister flange. The blister has a pull feature which is accessible for gripping by a user to engage and remove the blister from the front card and the back card. To separate the blister from the cards a user grips the pull feature and pulls the blister frontwardly, thereby distorting the blister and extracting the blister from the cards, to fully separate the blister from the front card and the back card, permitting the entire package to be recycled.Type: GrantFiled: May 31, 2019Date of Patent: November 19, 2019Assignee: Placon CorporationInventor: Donald E.

Patent number: 9352886Abstract: A container has features to indicate tampering and to discourage reuse as a deterrent to use with counterfeit goods. A lid hinged to a thermoformed thermoplastic base defines a product compartment. A line of weakened material surrounds a retention tab within a base upper wall. The tab is secured to a lid upper wall such as by a weld. The retention tab is secured to the lid through an opening in an enclosure element such as a card of thermoformed sheet. When the lid is separated from the base the retention tab is detached from the base along the weakened line of material and retained by the secured connection to the lid with the enclosure element retained by the retention tab to the lid upper wall. The retention tab interferes with the removal of the enclosure element from the lid and its reuse with counterfeit goods.Type: GrantFiled: November 21, 2013Date of Patent: May 31, 2016Assignee: Placon CorporationInventor: Jeffrey S.

Publication number: 20140284346Abstract: A clamshell container has a lid connected to a base by an integral hinge. The lid has a perimeter projecting member which engages with a peripheral base sealing wall in a closed configuration so that it is difficult for a user to open the container without tearing the lid along a weakened region of material along the hinge. To aid in resisting undetectable tampering, the container has a post which projects from the side wall and extends less than the length of the side wall within the container. The post has an engaging wall which faces towards a base sealing wall and which is spaced from the sealing wall to define a gap which receives the closed lid's projecting member. Distortion of the closed container which tends to urge the lid projecting member away from the base sealing wall engages it with the post engaging wall to resist tampering.Type: ApplicationFiled: March 21, 2013Publication date: September 25, 2014Applicant: Placon CorporationInventor: Donald E.

Patent number: 8083093Abstract: A container has a base with a bottom wall rib structure which deforms downwardly when an unresisted load is applied. The rib structure stiffens the base, and also can elevate the food product from liquid within the container. The bottom wall has a central platform which extends upwardly from a lower encircling segment. The lower encircling segment marks the lowermost portion of the base as molded, and extends inwardly from the lower margin of the sidewall. Two generally parallel longitudinal ribs extend across the platform and project upwardly from the platform. The longitudinal ribs extend from the lower encircling segment at the front of the base to the rear of the base. Short bridging ribs are evenly spaced parallel to one another and extend laterally between and connect the two longitudinal ribs. A plurality of cross ribs extend outwardly from each longitudinal rib to the encircling segment.Type: GrantFiled: September 16, 2010Date of Patent: December 27, 2011Assignee: Placon CorporationInventor: Donald E.

Patent number: 7823746Abstract: A container for carry out heated food items, such as rotisserie chicken, has a base which is connected to a lid by a mating peripheral closure which defines a liquid tight seal. The closure has an encircling inclined wall on the base, which helps to direct the lid into engagement with the base, and which also defines a cavity within the closure which can retain liquid. The base may be provided with two fold up straps which are retained by structure in the lid to lie generally flat to serve as a convenient carrying handle above the lid. The base has rib structure allowing it to distend downwardly when loaded with food to space the heated food from the customer's hand while engaged with the handle.Type: GrantFiled: December 22, 2005Date of Patent: November 2, 2010Assignee: Placon CorporationInventor: Donald E.

Publication number: 20070278122Abstract: Two food elements are supplied in a container assembly which may be placed on a horizontal support surface or supported in an automobile cup holder. A smaller secondary cup is received within a secondary cup cavity cantilevered to one side of a thermoformed thermoplastic primary container which has exterior dimensions suited to a cup holder. The primary container has a main compartment which receives another food element. The base of the primary container is inclined from the rim of the primary container, such that the center of gravity of the primary container with secondary cup and edible material overlies the primary container bottom wall when the bottom wall is supported on a horizontal surface. A column in the primary container side wall extends from a protruding toe portion of the bottom wall to engage and support the secondary cup cavity.Type: ApplicationFiled: May 11, 2007Publication date: December 6, 2007Applicant: Placon CorporationInventors: Donald E.

Patent number: 6330945Abstract: A hanging clamshell package has a thermoformed plastic blister with a cover pivotally connected by a hinge to a base. The cover has a curved rearwardly opening front wall. A product bubble protrudes frontwardly from the cover front wall and has a curved front face. A bubble top wall extends between the cover front wall and the bubble front face, and beneath the bubble top wall, a bubble bottom wall extends between the cover front wall and the bubble front face, the forward extension of the bubble top wall is less than the forward extension of the bubble bottom wall, tending to counteract the visual impact of product settling. The base has a curved rearwardly opening base front wall of approximately the same curvature as the cover front wall. A card is clasped between the cover front wall and the base front and is thereby conformed to a curvature approximately matching that of the cover front wall.Type: GrantFiled: June 30, 2000Date of Patent: December 18, 2001Assignee: Placon CorporationInventor: Joe Reimer

Patent number: 5819939Abstract: A thermoformed thermoplastic blister is connected to a backing card. The blister has a peripheral flange which is positioned adjacent the backing card, and a bubble which protrudes frontwardly from the flange. A catch is formed in the flange, and is deformed rearwardly through an opening in the card to extend downwardly. The plastic catch extends into a narrow slot on the bubble of another like package. The slot is approximately the same width as the catch and need be only slightly taller than the thickness of the flange. With this connection structure multiple packages may be supported one upon another. In addition, the packages will automatically link to one another when extracted from a shipping carton. The rearwardly protruding catch may be formed from the plastic flange alone, or may be formed together with a portion of the backing card for additional strength.Type: GrantFiled: October 23, 1997Date of Patent: October 13, 1998Assignee: Placon CorporationInventor: David C.
