Definitions

  • the present invention relates to folding carton containers. More particularly, it is concerned with a sealed container having a hinged cover that may be opened and subsequently reclosed, i.e., "flip-top.” Reclosure engages locking members that not only secures the cover to the container, but results in an audible noise as well. Additionally, the container includes a tamper-evidence feature.
  • Flip top containers are known in the art. Such containers include a cover or top that is hingedly connected to the top edge of a wall of the container. It is also known that such containers may provide various locking mechanisms or devices for securing the cover to the container after the cover has been initially opened. In other words, after the seal affixing the cover to the container has been broken, the locking mechanism holds the cover in a closed position.
  • Some representative containers of this type are illustratively disclosed in U.S. Pat. Nos. 3,191,848, 3,378,188, 3,893,614, Re 26,471, 3,294,309, 3,295,742, and 4,215,783.
  • a container formed from an integral blank with a configuration having a top section and a bottom section attached to each other by a first line of weakness such that upon the application of sufficient pressure, the first line of weakness breaks the attachment of the top section from the bottom section.
  • a cover is formed from the top section that is hingedly attached to the bottom section at the rear wall panel.
  • a releasable locking device having a first locking member on the cover is attached by a second line of weakness to a second locking member on the front wall portion. The first locking member and second locking member is in an aligned relationship such that when the second line of weakness is broken, the cover pivotally moves to the open position and a recess is formed between the front panel and side panels and the inner body portion.
  • the cover pivotally moves from the open position to the closed position, the first locking member and the second locking member engage to secure the inner body portion with cover in a closed relationship.
  • an audible sound is emitted when the first locking member engages with the second locking member.
  • FIG. 1 is a plan view of a blank for forming the container of the present invention
  • FIG. 2 is a perspective view of the formed container with the cover closed
  • FIG. 3 is a perspective view of the formed container with the cover open
  • FIG. 4 is an enlarged view of the line of weakness in FIG.2.
  • a flip-top container is provided that is formed from an integral, e.g., a single, blank.
  • the container has bottom, front, rear, and side panels, and a cover or top.
  • Locking members are provided at the upper edge of the front wall panel and on the corresponding inner surface of the cover. The locking members on the wall panel and the cover are in cooperative relationship to one another to retain the cover in a closed position after opening.
  • the present invention also relates to a unopened flip-top container having top and bottom sections affixed or linked to one another by a continuous line of weakness, wherein the container top section can be pivoted about an integral hinge formed with the rear wall panel of the bottom section, i.e., hingedly attached. Opening the unopened container is preferably begun by lifting a grasping member, which is located on the cover. Opening an unopened container for the first time results in breaking the continuous line of weakness between the top and bottom sections, thereby creating a cover that is hingedly attached to an upper edge of the rear panel of the container.
  • any break or other discontinuity along the continuous line of weakness between the top and bottom sections, before the container is opened for the first time provides an indication of possible package tampering.
  • the hingedly attached cover is maintained in closed position using at least one locking mechanism or means.
  • locking means has a first locking member and a second locking member, as described more fully below.
  • the separate locking members are initially joined together by a continuous line of weakness that is broken upon the initial opening of the cover.
  • the first and second locking members engage upon closing, preferably emitting an audible snap sound.
  • Blank 10 includes front wall panel 20 connected to first cover portion 104 and first bottom portion 114 by crease score lines 24 and 26, respectively; first side wall panel 40 connected to second cover portion 102 and second bottom portion 112 by crease score lines 44 and 46, respectively; second side wall panel 50 connected to third cover portion 106 and third bottom portion 116 by crease score lines 54 and 56, respectively; and back wall panel 30 connected to fourth cover portion 108 and fourth bottom portion 118 by hinge score line 34 and crease score line 36, respectively.

  • lines of weakness 60 and 70 have substantially constant resistances to separation along their length.
  • the continuous line of weakness 60 is a scored line, then it is of constant depth and density.
  • the continuous line of weakness 60 is a perforated line, the dimensions of the perforation components and the land components residing between adjacent perforation components may or may not be constant. This can be seen more readily in FIG. 4.
  • Properties of the continuous lines of weakness 60 and 70 may vary slightly in the corners of the container to impart strength properties and facilitate opening by the consumer.
  • Continuous lines of weakness 60 and 70 can be made using any known mechanical means, such as scoring or perforating; chemical means, such as chemical etching; physical means, such as a laser; or combinations thereof.
  • Each continuous line of weakness 60 and 70 can be a single line, or alternatively a series of lines, such as those that make up a tear strip configuration.
  • FIG. 4 is an enlarged view of area 200 of FIG. 2, illustrating one embodiment of the continuous line of weakness 70 having perforation components 96 and land components 98. While only continuous line of weakness 70 is shown in this view, it is understood that continuous line of weakness 60 may be equivalent to continuous line of weakness 70.
  • perforation component 96 and land component 98 are preferably adjusted to the material selected in order to ensure protection of the articles prior to initially opening the container top section 100, while also allowing easy and clean opening of the container.
  • perforation component 96 represents an elongated separation that extends along line of weakness 70 between land component 98.
  • a plurality of perforation components 96 extend along the continuous line of weakness 70 are preferably about 1.5 to about 25 millimeters in length, more preferably about 3 to about 4 millimeters in length.
  • a plurality of land components 98, preferably adjacent to at least one perforation component 96, along the continuous line of weakness 70 are preferably from about 1 to about 4 millimeters in length. Smaller lands often result in failure during container folding and filling.
  • Slit portions 72, 74 and 76 are preferably about from about 10mm to about 20mm respectively. Longer slit portions are preferred over shorter slit portions to minimize the force to initially open the container. Combinations of perforation, land, and slit areas will vary for containers of varying sizes and materials. While not required, it is nonetheless preferred that a slit portion is located in line of weakness 70 closed to top section 100. While the preceding has described line of weakness 70, it is understood that line of weakness 60 is similar. Breaking or severing continuous lines of weakness 60 and 70 allows for opening container 12 into two portions, cover 100 and bottom section 110 wherein cover 100 is hingedly attached to bottom section 110, hence creating a flip-top container. By lifting cover 100, articles contained in container 12 can be displayed, i.e, viewed, or dispensed.
  • first locking member 82 is affixed to the top of the inner surface front wall panel 20.
  • Second locking member 84 is hingedly connected to crease score line 84a of first wall portion 22 and articulates into juxtaposition with second surface 22b.
  • upper edge 85 of second locking member 84 is disengaged from first locking member 82 by breaking of line of weakness 84d when cover section 100 is lifted during initial container opening.
  • Grasping member 90 can be optionally employed to aid in separating container top section 100 from container bottom section 110.
  • at least one grasping member 90 is employed such that separation of top section 100 from bottom section 110 is commenced from a central position upon lifting or grasping and pulling grasping member 90.
  • grasping member 90 is :+:
  • Grasping member 90 can be engaged and begin separating container top section 100 from container bottom section 110 in a single step.
  • Grasping member 90 is defined by flexible line of weakness 92. After initial opening of the container, flexible line of weakness 92 may exhibit a slight resiliency that results in grasping member 90 bowing outwards away for outer surface of front wall panel 20. This bowing assists in facilitating opening of container top section 100 from container bottom section 110. Additionally, the bowing helps to prevent tearing about grasping member 90.
  • Grasping member 90 should be of sufficient size and geometry to readily receive at least the tip of one human finger. Alternately, grasping member 90 may be removed. Various other tools, such as a hook, could be inserted into grasping member 90 for separating container top section 100 from container bottom section 110. Because the initial opening of the container requires some force to tear or the lines of weakness, it may be desirable to construct grasping member 90 from a heavy or rigid material to prevent tearing upon the initial opening of the container.
  • the first locking member 82 including tabular portion 90a, is adhered to the inner surface of front wall panel 20 to provide thickness and support.
  • grasping member 90 is of ovoid shape, but may be any convex shape, concave shape, or a combination thereof. It has been found that augmenting the functionality of grasping member 90 may be accomplished by implementing scores at either or both side ends of grasping member 90. Additionally, it is preferred for ease of use that opening area 94 separate grasping member 90 from outer front wall panel 20.
  • a representative, non-limiting list of materials useful in constructing the container includes corrugated board (polymeric, paper, and the like), paperboard, paper laminations, chipboard, polymeric sheeting, foam board, and combinations thereof, preferably the material is paperboard.
  • Preferred paperboard is 16pt or 250 g/m 2 paperboard, solid bleach sulfate (SBS) or recycled paperboard.
  • SBS solid bleach sulfate
  • corrugated board comprises E-flute corrugations.

Abstract

Cette invention concerne un emballage constitué par une ébauche d'une seule pièce (10) présentant une partie supérieure (100) et une partie inférieure (110) reliées l'une à l'autre par une première ligne de fragilisation (60, 70) de telle sorte que sous une pression suffisante, cette première ligne de fragilisation rompt la liaison entre les parties supérieure et inférieure. Suite à cette séparation, un couvercle est formé à partir de la partie supérieure, laquelle est reliée pivotant à la partie inférieure au niveau du panneau arrière. Un dispositif de fermeture libérable (80) comportant un premier élément de fermeture (82) sur le couvercle est relié via une seconde ligne de fragilisation (84d) à un seconde élément de fermeture (84) sur la partie constituée par la paroi avant. La relation d'alignement entre le premier et le second élément de fermeture est telle qu'au moment de la rupture de la seconde ligne de fragilisation, le couvercle pivote sur la position ouverte et un renfoncement se forme entre le panneau avant et les panneaux latéraux et la partie d'élément intérieur. Lorsque le couvercle pivote de la position ouverte sur la position fermée, le premier élément de verrouillage et un second élément de verrouillage s'engagent et assurent la fixation de la partie inférieure et du couvercle en position de fermeture. L'engagement du premier élément de fermeture dans le second élément de fermeture déclenche éventuellement l'émission d'un son audible.
