A steam release standing pouch has a structure in which the sealing portion is reliably peeled, and a content sealing standing pouch formed using the pouch. The steam release standing pouch has a first vapor passage portion. The distance between the inner edge of the tip of the vapor passage portion and the center of maximum expansion, which is the center of the portion where expansion is expected to be maximal, is shorter than either the distance between the inner edge of the first upper side portion and the center of maximum expansion or the distance between the inner edge of the first intermediate side portion and the center of maximum expansion.

The present invention relates to an instant cooking heating bag and, more specifically, to an instant cooking heating bag of which an inner bag, in which food is to be accommodated, is put into an outer bag so as to be integrally formed by the binding of the inner bag with the outer bag, provided with a heating agent and an aqueous solution bag in a space formed between the outer bag and the inner bag, and provided with a cutting means connected to the aqueous solution bag, so as to allow food to be heated and cooked instantly by a user's simple manipulation of pulling the cutting means, thereby allowing warm food to be conveniently consumed outdoors without using additional cooking utensils. An instant cooking heating bag according to the present invention comprises: an outer bag of which the upper part is open and the lower part is closed such that the upper end part is bound so as to seal the inside of the outer bag in a state in which contents are accommodated therein; an inner bag accommodated inside the outer bag such that the upper part thereof is open and the lower part thereof is closed, thereby allowing food to be accommodated therein and providing an opening/closing zipper at the opening of the open upper part; and a heating agent accommodated in a heating space formed between the outer bag and the inner bag and generating heat by reacting with an aqueous solution, and the instant cooking heating bag further comprises: an aqueous solution bag accommodated in the heating space and in which an aqueous solution, causing the reaction of the heating agent, is put; and a cutting means of which one end is connected to one side of the aqueous solution bag so as to cut the aqueous solution bag by being pulled by an external force, wherein the border of one side of the aqueous solution bag is bound to the inner surface of the outer bag along a first binding line.

Disclosed are disposable containers, such as a stand-up pouch, for heating food in a microwave oven and while automatically dispensing sauce onto the food. Methods and apparatuses for making sauce packets and disposable containers are also disclosed.

A container comprising a first layer of sheet material defining a compartment for holding a fluid material, first and second peripheral edges defining lateral boundaries of the compartment, a first end defining an opening end and a channel having a first cross sectional diameter extending into the compartment between the peripheral edges, a second end defining a bottom of the compartment, a valve comprising a first layer of flexible material of higher stiffness than the sheet material on a first side of the channel, a valve positioned on a second side of the channel, where the first layer and the valve are joined on opposite sides of the channel via attachment means restricting the first cross sectional diameter of the channel where a deflection of the flexible material in a direction substantially perpendicular to the longitudinal axis provides increased resistance to deflection in the direction along the longitudinal axis.

The present invention is directed to a packaging article configured as packaging rollstock comprising a multilayer laminate having an integrally formed peelable, removable coupon. The coupon is formed from a first layer having at least two score-lines and a pattern-applied second, third, fourth and fifth layer. The coupon includes an interior printable water-based acrylic pressure sensitive adhesive layer which advantageously provides a surface for printing graphics and resealability to packages made there-from.

A pouch container (1) for a food product, a filled container, and a method of filling are described. The container (1) comprises a sheet containment material configured surroundingly and sealingly to define a food containment volume, at least one closure seam (7) provided within the volume between paired opposing surfaces of the said sheet containment material to divide the containment volume into two food compartments (8,9) suitable to contain food product in use, wherein the said closure seam (7) has a pressure sensitive apertured portion (14) adapted to be closed at ambient pressure but to open when an internal pressure differential between the compartments reaches a predetermined point.

Methods of making non-durable self-supporting flexible containers.

A flexible container comprising a multilayer structure which comprises a barrier layer; a sealing layer, and a third layer between the barrier and sealing layers which comprises a foamed polyolefin, wherein the container includes crease lines formed by localized thermal compaction of the foamed polyolefin is provided. Also provided is a method of making a flexible container.

A sheet material container includes a container body that surrounds a containing portion for accommodating a content. The container body is formed of a container body-forming sheet member formed by layering a plurality of base material films. The container body-forming sheet member includes the plurality of base material films, an attaching layer by which the base material films are attached to each other, and a filler enclosed portion that is formed between the plurality of base material films and into which a filler is to be filled. The plurality of base material films are made from the same type of resins.

A non-durable flexible container can include a first film wall including a first portion comprising at least one first structural support member defined in the first film wall, and a second portion that is free of a structural support member. The container can further include a second film wall including at least one second structural support member defined in the second film wall, wherein at least a portion of the first structural support member is adjacent to at least a portion of the second structural support member to define a seam region, and a side of the seam region defines an edge of the non-durable flexible container. The container can also include a closed produce volume defined between first and second film walls; and a seam projecting outwardly from the seam region at an intersection of the first and second film walls.
