A steam-releasing pouch includes two laminated sheets forming an accommodation compartment that accommodates a content, a sealing portion that seals the two sheets to form an opening that opens part of the accommodation compartment, and a steam-releasing sealing portion formed in the sealing portion to open as pressure of the accommodation compartment increases in a state in which the opening is sealed. The steam-releasing sealing portion includes a first sealant layer having at least a first base layer that faces the accommodation compartment and a second base layer laminated with the first base layer and a second sealant layer having at least a third base layer that faces the accommodation compartment and a fourth base layer laminated with the third base layer. The first base layer and the third base layer are joined together.

A bag for containing one or more items to be heated in a microwave oven. The bag has a front panel and a back panel and has a seal across the containment region to split it into two compartments each containing at least one item such as a food ingredient. When the bag is heated, the compartments expand due to gas expansion and the seal is caused to break to allow the items to mix and be heated together.

Embodiments include a container with a leak resistant seal. The leak resistant seal provides access to the inside of the container when the leak resistant seal is open. The leak resistant seal includes first and second seal portions that are configured to be coupled together to close the container. A gap is arranged between ends of the first seal portion and the second seal portion, which provides an abutment that each of the ends of the first and second seal portions contact when the first seal portion is coupled to the second seal portion.

The present invention relates to a cooking pouch, and more particularly, to a cooking pouch that has a reduced manufacturing unit price and is used to heat food by placing food inside the cooking pouch and putting the cooking pouch inside a microwave, and the cooking pouch enabling steam generated in a cooking process to be appropriately discharged so that excellent food texture and taste may be obtained.

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. eodcmaster

A container includes a bag, which has an internal space to accommodate contents and a first opening, and a fastener to open and close the first opening. The bag places contents into the internal space through the first opening. The bag also has a second opening and also places contents into the internal space through the second opening.

A container includes an outside portion forming an external surface of the container, an inside portion forming an internal surface of the container, and a container seal arranged on the internal surface and configured to open and close the container for providing access to the inside portion. The container seal includes a male seal portion arranged on the internal surface of a first side of the container, a female seal portion arranged on the internal surface of a second side of the container, a gap between a first end of the male seal portion on the first side of the container and a second end of the female seal portion on the second side of the container, and at least one gap seal that is disposed within the gap, between the male seal portion and the female seal portion.

A vented sealable bag comprises a container, a two-part seal and a vent. The container has opposing sidewalls and a bottom defining a cavity. The sidewalls form a neck defining an opening opposite the bottom, The sidewalls have an inner surface facing the cavity and an outer surface external to the container and the sidewalls have a thickness. A two-part seal is formed on the inner surface of the sidewalls adjacent the neck. The two-part seal has a hook formed on one sidewall and a clasp formed on an opposite sidewall. The hook and clasp are arranged on the inner surface of the sidewalls to form an airtight seal isolating the cavity from an external environment when the hook is embedded in the clasp but otherwise maintain the opening in the container. A vent is integrally formed in one of the sidewalls. The vent is further comprised of a dimple having a thickness that is thinner than the thickness of the sidewalls. The dimple is concave when viewed from the cavity and has a slit formed at an apex that is closed except when the container is sealed and an internal pressure is created that is higher than an external pressure on the outer surface of the sidewalls.

A zipper tape includes a pair of belt-shaped bases bondable to a film of a bag body, and mutually engageable engagement portion each integrally provided to corresponding one of the belt-shaped bases. One of the belt-shaped bases includes at least two portions having different bonding strengths to the film on a side opposite a side provided with the engagement portion and between an edge of the one of the belt-shaped bases in a width direction orthogonal to a longitudinal direction to a point at which the engagement portions are provided. A bonding strength of a first portion of the at least two portions to the film may be larger than a bonding strength of a second portion to the film.

A packaging bag including a polyester-based multilayer film. The multilayer film includes at least: an innermost layer formed of a biaxially stretched polyethylene terephthalate film; a layer formed of polybutylene terephthalate; and/or a layer formed of a blend of polyethylene terephthalate and polybutylene terephthalate. The biaxially stretched polyethylene terephthalate film has a heat sealing portion that is amorphized or low-crystallized by laser light irradiation. The packaging bag is formed by allowing the innermost layers of the polyester-based multilayer film to be opposed to and superimposed on each other, and heat sealing the heat sealing portions.
