Problems solved by technology

[0004] However, in this technology, there are problems as follows: it is difficult to adjust the discharge amount of steam, and the steaming effect of the content is poor because the peeling of the V-shaped portion starts too early, and there is a problem that it is difficult to reach the end of the cover member from the inner tip of the V-shaped portion. The relatively long distance of the part causes the beeping sound when the steam is released
In addition, there is also a problem that since the peeling of the cover member is easy to expand, when the steam is discharged and the pressure is reduced, the water droplets remaining in the part surrounded by the V shape or the film constituting the cover member will clog due to the discharge of the steam. , when the main body of the container deforms due to decompression

Embodiment approach 1

[0040] (The overall structure of the container for microwave oven)

[0041] First, based on figure 1 The overall configuration of the container for a microwave oven according to Embodiment 1 will be described. picture figure 1 As shown, the container 10 for a microwave oven mainly includes a container main body 20 having an opening 21 and filling the contents 11 from the opening 21 , and a film-shaped lid member 50 closing the opening 21 . Both the container main body 20 and the lid member 50 are formed of a resin material. The contents 11 stored in the container main body 20 are various foods and the like, as long as they can be heated in a microwave oven, the type is arbitrary.

[0042] Further, container 10 for microwave oven includes flange portion 22 , second heat-welded portion 23A formed on the upper surface of flange portion 22 and heat-sealed to lid member 50 , and first heat-sealed portion 23B on its outer peripheral side. Furthermore, the container 10 for a micr...

Embodiment approach 2

[0070] Below, based on Figure 8 Embodiment 2 of the present invention will be described. In Embodiment 2, in the W-shaped portion 27 (easily peelable portion) in Embodiment 1, the inner central tip portion 27b is made lower than the inner two root portions 27c, 27c, and the height difference is h2. That is, the central two side portions 27d, 27d connecting the outer two tip portions 27a, 27a and the inner central tip portion 27b are formed more gentle than the root side portions 27e, 27e connecting the outer two tip portions 27a, 27a and the inner two root portions 27c, 27c. The inclination angle θ2. With this configuration, when the lid member 50 is thermally welded to the flange portion 22 of the container body 20, the central two sides 27d, 27d and the root two sides 27e, 27e sandwiching the outer two sharp ends 27a, 27a can be heated. Since the strength of welding is more different, the stress on the vapor pressure of the outer tip portions 27a, 27a is more concentrated...

Embodiment approach 3

[0073] Below, based on Figure 9 A container body according to Embodiment 3 of the present invention will be described. In Embodiment 3, the planar shape of the storage portion 20b is a substantially oval shape with rounded corners. picture Figure 9 As shown, the container main body 70 has the storage part 20b and the opening 21 whose planar shape is substantially rectangular. The flange portion 22 extending from the opening 21 is provided with a ridge-shaped second heat-sealing portion 23A and a ridge-shaped first heat-sealing portion 23B. Furthermore, the first heat-sealing portion 23B has a W-shaped portion 71 , and the W-shaped portion 71 is formed in a W-shape so as to close outward at a position corresponding to the steam discharge portion 25 in plan view. The W-shaped portion 71 has two outer two tip portions 71a, 71a facing outward, one inner central tip portion 71b facing inward, and two inner root portions 71c, 71c connected to the first thermally welded portion ...

Abstract

Provided is a microwave oven container that adjusts vapor emission amount, suppresses squealing noise at the time of vapor emission, and prevents water drops from remaining in the container, in a structure that allows further prevention of content leakage. A microwave oven container 10 is characterized by being provided with: a container body 20 having an opening 21 on the upper part thereof; a flange part 22 that is formed to extend outward from the opening 21 of the container body 20; and a first thermal welded part 23B that is provided on the entire circumference of the upper surface of the flange part 22 and that is thermally welded to a film-shaped lid member blocking the opening 21, wherein the first thermal welded part 23B has an easily separable part 27 that extends outward and closes in a planar view, and the easily separable part 27 is configured to be separable from an outer end part 27a.

Description

technical field [0001] The present invention relates to a container for microwave ovens. Background technique [0002] Conventionally, various techniques have been proposed regarding containers for microwave ovens (for example, refer to Patent Document 1). [0003] Patent Document 1 discloses a technology of a hermetic container having a peelable heat-sealing tape in order to automatically open a part of the container due to an increase in internal pressure caused by steam expansion or the like, and forming at least one portion of the heat-sealing tape One position protrudes toward the inner side of the container, and the inner tip of the protrusion (inwardly convex V-shaped portion) is opened due to an increase in internal pressure. [0004] However, in this technology, there are problems as follows: it is difficult to adjust the discharge amount of steam, and the steaming effect of the content is poor because the peeling of the V-shaped portion starts too early, and there...
