Definitions

  • Food is often placed in a transparent plastic container that includes a base with a large volume cavity that holds the food and with a cover or lid that closes the cavity.
  • Buyers want to be assured that, after the food was placed in the container as by a clerk at the food store, that the container has not been opened. There is a possibility that another customer has secretly opened the container enough to taste a bit of the food before closing it (and possibly leaving germs from his/her finger in the food). Potential buyers want to be assured that this has not happened.
  • a container constructed by the container manufacturer that allowed a clerk at the store to automatically activate a device that clearly indicated to a potential customer whether or not the container has been opened since it was first closed by the clerk, would be of value.
  • FR-2819496 discloses cheese packaging comprising a base for receiving the cheese and a cover whose bottom is fitted on a bead around the base.
  • the cover has a flange at two opposed corners and the base has corresponding retaining tabs that are joined to the rest of the base by weakened links.
  • the corner flanges of the cover are, when the packaging is closed, caught under the corner tabs of the base, but are released when the corner tabs are broken off by severing the links holding them to the rest of the base.
  • a container of the type that includes a base and lid, which allows the lid to be closed and thereafter prevents the lid from being opened unless a barrier is broken.
  • the container and lid each have trapping portions and pull-open portions-with a tear-open barrier on-the base of the pull-open portion.
  • the tear-tab, or tear-open barrier forms the upper wall of a horizontal slot.
  • the pull-open portion of the lid has a pull-up tab that is projected through the slot when the lid is closed.
  • the barrier To open the lid, the barrier must be broken in breakable joints extending from said slot to the outer edge of the base, so the pull-up tab on the lid can be pulled up to release the lid from the base. This configuration facilitates breaking off the barrier compound to the design of FR 2 819 496 .
  • the trapping side of the base has a trapping wall that extends at a downward-outward incline (with respect to the container axis) and has a stop wall that extends radially inward from the bottom of the trapping wall.
  • the lid has a peripheral lip that can be pressed down along the trapping wall until the lip reaches the stop wall. The lip then cannot be raised so the lid is trapped in the closed position until the barrier is torn so the pull-up tab can be pulled up.
  • the base has a seal wall lying below the stop wall, the seal wall having a concave radially inner surface that extends at a downward-inward incline.
  • the lid has a corresponding seal wall with a convex outer surface that lies facewise against the concave surface of the base to form a fluid tight seal.
  • Figs. 1 and 2 show a bowl-shaped container 10 of the invention, which includes a base 12 and a lid 14 that can be closed on the base.
  • the base has a trapping portion or section 20 that receives a trapping portion or section 22 of the lid and thereafter resists lid removal.
  • the base also has a pull-open portion or section 24 with a horizontally open slot 26 that receives a lift tab, or pull-up tab 30 of a pull-open portion or section 32 of the lid.
  • the trapping sections of the base and lid preferably extend at an angle A of at least 300° (with a possible interruption) around the vertical axis 34 of the container.
  • the trapping portion could extend 360°.
  • the pull-open portions of the base and lid extend by an angle B that is preferably less than 90° around the axis. If more than one pull-open section is provided the total angle B will increase.
  • the lid is installed in the manner shown in Fig. 6 , by holding the lid 14 at an incline C such as about 30° to the horizontal and to the top 40 of the base, and projecting the tab 30 of the lid through the slot 26 in the base. Then the trapping section 22 of the lid is pushed down forcefully into the trapping section 20 of the base. This results in the trapping section of the lid being trapped in place deep in the base.
  • Fig. 4 shows the trapping sections 20, 22 of the base and lid in their fully trapped positions.
  • the base has an outer edge part 50, and has a top flange or portion 52 extending radially inward of and above the base outer edge.
  • the term “radially” describes a direction with respect to the axis 34 of the container, so “radially inward” or just “inward” means toward the axis and “radially outward” or just “outward” means away from the axis. Terms such as “inner” surface means the surface closest to the axis.
  • the base shown in Fig. 4 has a trapping wall 54 extending at a downward and radially outward incline from the inside of flange 52, and has a stop wall 56 that lies at the bottom of the trapping wall.
  • the trapping wall is joined to the stop wall at a corner 58, and the stop wall extends at least partially radially inward from the corner 58.
  • the base also has an upper seal wall 60 with a concave inner surface 62, that extends at a downward-inward incline from a corner 64 at the inside of the stop wall.
  • the base has a lower seal wall 66.
  • the lid has corresponding walls, including a radially outward free peripheral lip 70, and an upper seal wall 72 with a concave inner surface 74 that is joined to the lip by a large radius corner 75 whose radius is larger than that of the base corner 64.
  • the lid also has a lower seal wall 76.
  • the inside radius of curvature of the lid corner 75 is at least 150% of the radius of curvature of the inside of the base corner 64.
  • the peripheral lip 70 of the lid snaps down to the position shown in Fig. 4 , with the lip 70 lying at the bottom of the trapping wall 54, at the corner 58.
  • the trapping wall 54 extends at a downward-outward incline from a vertical G, which is preferably between 5° and 30° to the vertical.
  • the peripheral lip 70 is unreinforced so it readily bends up when pushed down along the inside of the trapping wall, and then is trapped in place.
  • the peripheral lip 70 could be forcefully pulled up, but a person cannot firmly grasp the lip to pull it up, and it requires a large upward force to pull it up. It is easy to push down the lip into place but almost impossible to pull up the lip, unless the pull-open portion of the lid is first pulled up.
  • Fig. 5 shows the pull-open sections 24, 32 of the base and lid when the lid has been fully closed on the base.
  • the point 70A represents a location of the same height and radial position where the peripheral lip of the lid would lie at the bottom of the trapping wall at 54A, in the trapping portion of the container. Instead, the pull-open portion of the lid forms the lift tab 30, which projects primarily radially outward through the slot 26 in the pull-open portion of the base.
  • the position otherwise occupied by a trapping wall 54A on the base is devoid of the trapping wall along the pull-open portion.
  • the base has a tear-tab, or barrier wall, or barrier 80 that forms the upper wall of the slot 26 in the base.
  • the lid forms the pull-up tab 30 that projects primarily radially though the slot 26.
  • the slot 26 has a small enough height and the tab 30 has a sufficient radial length and has stiffeners 73 formed beside a hole 77 in the tab, that a person normally cannot bend the tab and push it inwardly to lie inward of the slot 26 to raise the tab. Instead, the only practical way for a person to raise the tab is to tear away the barrier 80.
  • Fig. 8 shows that the barrier 80 is attached by two tear joints 90, 92 to a major portion 94 of the base, which is primarily the trapping portion of the base.
  • the tear joints which extend perpendicular to adjacent parts of the edge 50, are weakened by perforations, notches or by a groove passing partway though the sheet at each tear joint.
  • the barrier has an indication 100, formed by the word "BREAK" that indicates that the barrier should be broken.
  • the lift tab 30 can be lifted.
  • the lid can be pulled along the upwardly inclined direction D ( Fig. 5 ) to remove the lid from the base.
  • the lid can be repeatedly closed and opened using only moderate force applied to the lift tab, and the container seals the contents each time the lid is closed.
  • Fig. 8 shows transition regions 110 at opposite sides of the trapping portion 22 of the base.
  • the plastic sheet of the base which is vacuum formed, has a flat portion between the ends of the flange 52.
  • the flange 52 forms the top 120 of the container and has opposite flange sides 122, 124 that strengthens the upper part of the base to support the weight of other similarly loaded containers that are stacked on one another.
  • a circumferential gap in the flange that is much less than 90°, such as the gap of about 35° occupied by the pull-open portion 32, allows stable stacking of the containers. It is possible to provide two or more pairs of pull-open section each similar to sections 24 and 32 and spaced about the container, although one pair is usually sufficient.
  • Fig. 9 shows another container 130 that is similar to the bowl-shaped container of Figs. 1-8 , but that has a regular polygon shape as seen in a plan view.
  • the particular container shown is of square overall parallelepiped shape.
  • the container 130 has a base 132 and lid 134 similar to that of the bowl-shaped container, except that the barrier wall 136 lies at one corner of the square shape.
  • the lid has a pull-up tab 137 that fits in a slot 138 under the tear-tab barrier 136.
  • Fig. 10 shows that the break lines 140, 142 of the barrier wall extend at angle G of about 45° (which is a plurality of degrees less than 90°) to adjacent sides 144, 146 of the square. If the break lines were positioned at 140a, 142a where they extended perpendicular to the sides, then this would result in projecting sharp corners, when the barrier 136 was torn off, which might hurt a person.
  • the invention provides a container with a base and lid, which enables a store clerk to close the container the first time, after loading food or other goods in the base, and which then prevents the container from being opened without breaking at least one end of a barrier.
  • the container has trapping and pull-open portions or sections. The trapping sections allow the lid to be forced down to a fully installed position and thereafter prevents the lid from being pulled up unless the lid pull-open section has been lifted and preferably also pulled away slightly from the center of the trapping portion.
  • the container forms a seal around the entire container circumference, which is broken only when the pull-up tab is pulled up.
