Embodiment Construction

[0033] Preferred embodiments are described in detail below. However, it should be understood that the present invention may be implemented in various forms. Therefore, specific details disclosed herein should not be construed as limitations of the present invention, but as a basis for the claims and as a typical basis for instructing those skilled in the art to use any suitably detailed system, structure, and Or apply the present invention under the mode.

[0034] figure 1 It is a top view of the package of the present invention. According to the present invention, a flexible three-side seal bag (100) is one form of a preferred embodiment. The flexible three-side seal bag consists of: a reclosable opening (101), preferably a zipper; channel means (103); and a weak seal area (104). The zipper (101) is pre-covered in some way by the channeling means (103). According to the present invention, figure 1 Also exemplifies a channeling device (103) that is pre-positioned in a ma...

Abstract

A packaging with improved reclosable opening is disclosed having a reclosable opening (101) for inserting object into the packaging, a diverting means (103) predisposed in such a manner and having a dimension sufficient to cover the reclosable opening to direct airflow away from the reclosable opening when there is an increase in internal air pressure. When increased internal air pressure has built up to a critical point, a weakened sealing (104) ruptures to allow air to vent through. The critical point is reached when the internal pressure is greater than external pressure to a sufficient extent to rupture the weakened sealing. The weakened sealing can be created by: a) using a heat sealing temperature which is lower than the sealing temperature used for forming the rest of the edge-to-edge sealing, b) having a designated sealing area smaller than the sealing area of the rest of the edge-to-edge sealing, c) forming a notch on part of the edge-to-edge sealing, d) disposing a film (202) between the front (102) and back (203) main packaging sheets on part of the edge- to-edge sealing, wherein the film is made of second material.

Description

technical field [0001] The present invention relates generally to the field of packaging, and more particularly to a package having an improved reclosable opening suitable for home use, and which is particularly suitable for packaging microwaveable food. Background technique [0002] Frozen or shelf foods that require microwave reheating are gaining in popularity. Excess or prepared foods can be packaged and stored. Consumers only need to heat these packaged foods in the microwave and eat them. [0003] When these foods are heated in a microwave oven, the moisture in the food is rapidly heated and converted into water vapor, and the pressure inside the package increases as the temperature of the package increases during heating. Consumers often poke holes or cut a corner of the package to allow water vapor to escape from the package during heating. [0004] Thus, packages with weak seals or vents can vent water vapor during heating, thereby allowing for improved microwave...
