Definitions

  • This invention relates to a food product container, and more particularly to a container having (i) a food container tray including a base, a sidewall extending from the base which terminates in a flange and, at least one projection made of a meltable plastic material extending from at least a portion of the flange and (ii) a food container jacket partially surrounding the food package tray.
  • Packaged foods and more particularly, the so-called "eat-in-box” foods are becoming increasingly popular with consumers. These foods offer the consumer a fast and convenient way to prepare and serve a meal. Typically, these packaged foods are bought in the frozen foods section of a supermarket, brought home and then cooked either in a conventional or microwave oven.
  • the "eat-in-box” foods offer the added convenience of allowing the consumer to merely place the entire food package into the oven, and when cooked, eat the food right out of the package. Thus, there is no need to transfer the packaged food to a separate cooking container or to a dish.
  • Another purpose of a food package is to provide a surface on which informational and marketing indicia are printed. For example, it is well known that an attractive food package can be influential in the consumer's purchasing decision. Thus, vendors of food products spend a considerable amount of time designing the packaging and labelling of their products.
  • the first is a die cut paperboard container having a paperboard lid.
  • the paperboard is coated with a plastic material, such as polyester, in order to make the paperboard ovenable.
  • microwave susceptor material such as aluminum, is interposed between the paperboard and the plastic material.

  • the heat seal die 98 applies heat to the lid 26, which heat is transferred through the lid 26 and then to the projection 90.
  • the heat melts the polyester coating 26b to the projection 90 to form a tight secure bond between the lid 26 and the horizontal flange portion 36.
  • the projection 90 provides several advantages. First, it provides a starting point to facilitate melting of the coating 26b to the horizontal flange portion 36. That is, the polyester coating 26b of the lid 26 initially contacts the projection 90 at point 94 and thus initially contacts the tray 22 at a smaller surface area. It will be appreciated that it is much easier to start to melt the point 94 because it has a smaller cross-sectional area, than it would be if there was no projection and the lid 26 would have to be melted directly onto horizontal flange portion 36. This allows a paperboard lid coated with polyester to be applied to a C-PETE base, something those skilled in the art have been unable to do successfully up to this time.
  • the projection 90 upon melting, can absorb variations in the wall thickness of the horizontal flange portion 36.
  • a problem in the prior art was that sealing a lid directly to the horizontal flange, if the horizontal flange had variations in thickness, can create gaps so that heat from the sealing die was not transferred from the lid to the horizontal portion. Because there is no melting of the lid to the flange at these gaps, the lid sometimes is not properly sealed, thus creating gaps through which air and contaminants could get into the package and through which the food in the package can leak out of the package.
  • the projection 90 when melted will tend to flow and even out the variations in wall thickness so that a secure and tight seal is made between the lid 26 and the horizontal portion 36.
  • the tray 22 itself may be formed such that portions of the horizontal flange portion 36 are at different heights. Without projection 90 this would mean that the lid would not contact the portions of the horizontal flange portion 36 that are lower than other portions of the horizontal portion. This causes the problems mentioned above. With the projection 90, even if the package is formed so that the horizontal flange portion 36 is disposed at different heights, the lid 26 contacts the point 94 of the projection 90 all around the horizontal flange portion 36 thus insuring a tight and secure seal between the lid 26 and the horizontal flange portion 36.

  • the tray 120 includes a non-circular base 122, which is shown in the Figures in the form of a rectangle although it will be appreciated that any shape of a tray can be used (such as circular or hexagonal, for example) and still be within the scope of the invention.
  • the base 122 is preferably made of C-PETE embedded with microwave susceptor material, such as aluminum or alumina although it will be understood that other materials, such as paperboard coated with a high temperature coating, such as polyester, can be used.

  • the interior gaps, such as gap 204, created between the pizza 180 and the base enhance the uniform heating of the pizza 180. Furthermore, the steam created by moisture in the frozen pizza which is heated is able to be vented from the bottom of the pizza 180 thus preventing sogginess of the pizza and creating a crispy crust. This steam also creates a "steam blanket" above the pizza 180 that enhances melting of the cheese on top of the pizza 180.
