Abstract
Description
- The present invention relates to packaging article, more particularly a stand up pouch for microwaving food products, particularly liquid food products, in the package.
- The amount of time available for preparation of meals has been steadily diminishing in recent years. Microwave cooking has been embraced by many consumers as one solution to the problem of dwindling meal preparation time. Microwave cooking often demands less attention than conventional oven cooking and is usually completed in a shorter period of time.
- But it is not enough merely to shorten the amount of time which must be devoted to cooking. For instance, consumers would also prefer not to have to expend effort washing or cleaning the microwave at the completion of microwave cooking, to the extent that this can be avoided. There is a need, therefore, for microwave packaging which can meet a variety of consumer needs, including easy opening and minimization of time spent cleaning the microwave.
- Numerous microwavable containers have been disclosed over the years.

Johnson et al. EP 823 388 Notch 23 may be included to facilitate initiation of the opening procedure.Hughes et al., U.S. Published Patent Application No. US2004/0118839 relates to a stand up pouch that is a convenient vehicle to eating, which uses a single partial tear for venting.Igota, et al., US Patent No. 6,121,597 , discloses a notched bag for microwave ovens capable of allowing escape of vapor generated during microwave heating using joints of different weaknesses. -
Chow, et al., US Published Patent Application No 2002/0068668 , discloses a method for producing an easy open, easy tear package using a laser. A microprocessor modulates the laser to create tear initiation areas along a score line. -
Tang, US Published Patent Application No. 2002/0001645 , is directed in Fig. 12 to a package made from an ACE sheet and an inner layer. The ACE sheet has nicks on each of two lines of weakness to permit sequential opening of three compartments. In the embodiment of Fig. 9j, prior to microwave cooking, the consumer tears the bag open along lines ofweakness 34 to create a small opening allowing partial release of gas vapor during cooking. Following microwave cooking, the bag may be opened using further aligned lines of weakness 45. The further aligned lines of weakness 45 may extend substantially parallel to thelines 34, no greater than 15 mm apart. -
JP-A-11-278556 - a bottom end and a top end;
- a first side wall end and a second side wall end extending between said bottom end and said top end;
- a top seal along the entire top end of said package;
- a splatter guard seal; and
- a tear area for removing a portion of said top end by facilitating cutting at least a portion of said side wall end;
said package resting on said bottom end; and said top seal and said splatter guard seal being spaced from each other by sufficient distance to create a tortuous path for venting vapors during microwave heating. - The present invention is directed to a new microwavable package having a seal so configured as avoid splatter of the product during heating or cooking in the microwave, thereby avoiding the need for the microwave to be washed after heating or cooking. The package is designed to permit venting of the package during cooking while minimizing the possibility for a messy and inadvertent escape of product onto, for example, the floor and walls of the microwave. The seal system sets up a tortuous path for vapors from food products, particular liquid food products, to travel during venting.
- The package according to the invention as defined in claim 1, comprises a bottom end and a top end and first and second side wall ends extending between the bottom and top ends. A top seal is provided along the entire top end to seal the package for storage of a food product. A splatter guard seal is situated a sufficient distance below the top end, spanning from the first side wall end approximately half way along and parallel to the top end.
- A tear area is provided which instructs cutting of at least a portion of the top end and of the first side wall. Removal of a portion of the top end along the tear area assists cooking of the package contents by permitting release of pressure accumulated within the package due to elevated temperatures. However, after the original top end is torn off, the splatter guard seal creates a tortuous path between the opening at the torn top end and the food contained within the package such that the chances of spattering of the product during cooking are essentially eliminated. The second partial seal, i.e., the splatter guard, prevents liquid food from splattering during microwave cooking.
- Since a purpose of the dual seal is to permit the food to be cooked without splattering into the microwave, there will generally be a vertical distance between the seals, preferably 25.4 mm (one inch), especially at least 6.35mm (0.25 inch), and at most 38.1 mm (one and one half inches) when the height of the pouch is 152-178 mm (6 to 7 inches). The important thing is that the dual seals have an adequate vertical distance between them and that their configuration creates a tortuous path, so that the goal venting without spilling is achieved.
- A label or graphics are provided on the pouch to indicate to the consumer where the pouch should be cut prior to cooking.
- The pouches may be sealed using a variety of techniques known in the art, including for example by way of laser sealer or ultrasonic sealer.
