Description

Technical Field

[0001] The present invention relates to a heat-generating pouch for portable cooking, and more particularly to a heat-generating pouch for portable cooking provided with a steam discharge guide capable of preventing accidents due to steam discharge in advance.

Background Art

[0002] A heat-generating pouch for portable cooking contains a metal heat-generating agent in a container of a certain capacity, pours water to cause a hydration reaction of the metal heat-generating agent, and uses the heat generated around 100 °C during the hydration reaction to heat and cook foods and the like.

[0003] In a conventional heat-generating pouch for portable cooking, a container is formed of a heat-resistant vinyl having a polymer of polyester and polyethylene as a material, an opening is formed at its upper end, and a closed space is formed in the vinyl container by closing a zipper for opening and closing provided at the opening.

[0004] Holes (steam holes) are formed in the upper side of the vinyl container to prepare for a rapid pressure expansion due to the hydration reaction of the metal heat-generating agent and water.

[0005] However, the holes (steam holes) formed in such a conventional heat-generating pouch for instant cooking have a structure in which the hot steam generated by cooking rapidly escapes to the outside along the holes and is ejected in the front and upper directions.

[0006] As a result, there is a high risk that a user may suffer a safety accident such as being burned by the hot steam discharged in the front direction or the upper direction of the face.

[0007] To address these issues, Korean Published Patent No. 10-2021-0109706, "Instant Cooking Heating Pouch," provides a solution by forming a steam outlet that includes a perforation line, a folding line, a steam outlet, a bent section, and a short wall. While this allows high-temperature steam to be released towards the ground, it is inconvenient because the user has to manually cut, fold, and bend the pouch each time. This is particularly inconvenient compared to containers that are portable yet require instant cooking. [Prior art documents] [Patent Documents]

[0008] (Patent Document 1) Korean Published Patent No. 10-2021-0109706 [Overview of the Initiative] [Problems that the invention aims to solve]

[0009] The technical problem that this invention aims to solve is to prevent safety accidents such as burns caused by high-temperature steam by forming a steam discharge guide that allows the high-temperature steam generated during portable instant cooking to be discharged towards the ground.

[0010] Furthermore, in the case of combat rations, the objective is to provide a heat-generating pouch that allows steam generated in tactical situations to be discharged upwards, thereby preventing the location from being exposed due to the steam.

[0011] Furthermore, given the usage characteristics of portable instant cooking heating pouches, we aim to provide a heating pouch that does not require any series of operations by the user to direct the steam towards the ground, and does not require any additional steps in the manufacturing process.

[0012] The problems that this invention aims to solve are not limited to those mentioned above, and any other problems not mentioned can be clearly understood by a person with ordinary skill in the art to which this invention pertains from the following description. [Means for solving the problem]

[0013] To achieve the above objective, the present invention provides a portable cooking heating pouch having a steam hole for steam discharge, which includes a steam discharge guide that covers the steam hole and is attached to the front surface of the heating pouch, wherein the steam discharge guide may consist of a U-shaped adhesive portion that opens downward and is bonded along the U-shape, and a steam discharge non-adhesive film that is formed inside the U-shape of the U-shaped adhesive portion and is not bonded.

[0014] Here, the U-shaped adhesive portion may be bonded in a manner that covers the steam hole, and the steam discharged through the steam hole may be configured to be discharged downward (towards the ground) through the steam discharge non-adhesive film.

[0015] Here, the U-shaped adhesive portion may have double-sided adhesive properties, with the steam-discharging non-adhesive film attached to one side and the other side attached to the heating pouch in a manner that covers the steam hole. [Effects of the Invention]

[0016] According to the configuration of the present invention described above, it is possible to discharge high-temperature steam towards the ground, thereby preventing safety accidents such as burns caused by high-temperature steam.

[0017] Furthermore, by releasing high-temperature steam towards the ground, it is possible to prevent the location from being exposed when using combat rations in the military.

[0018] Furthermore, due to the characteristics of the portable instant cooking heating pouch, no user action is required to direct the steam towards the ground, and no additional steps are needed in the manufacturing process, thus avoiding issues such as increased manufacturing costs.

[0019] However, the effects of the present invention are not limited to those described above, and can be broadly extended without departing from the spirit and scope of the present invention. [Brief explanation of the drawing]

[0030] A heating element is used to cook food, and a steam hole 14 may be included at the upper end of one side to allow the high-temperature steam generated during cooking to be discharged to the outside.

[0031] The materials, joints, heating elements, and zipper structure for manufacturing the portable cooking heating pouch 10 can be various commonly known configurations, and a detailed explanation will be omitted in order not to obscure the gist of the present invention.

[0032] The portable cooking heating pouch 10 according to the present invention may further include a steam discharge guide 15 so that when hot steam generated in the internal space is discharged to the outside as exhaust steam, it is discharged towards the ground.

[0033] The steam discharge guide 15 may be formed in a manner that covers the steam hole 14 and is adhered to the front surface of the container 11.

[0034] Figure 2 is a perspective view of a steam exhaust guide for a portable cooking heating pouch according to one embodiment of the present invention.

[0035] Referring to Figure 2, the steam discharge guide 15 may be formed in a structure that is bonded to cover the steam discharge hole 14 located at the upper end of the front film of the container 11.

[0036] In the existing heat-generating pouch configuration, only an adhesive process is added at the location of the steam hole 14, eliminating the need for additional processes and offering the manufacturing advantage of being able to utilize existing equipment as is.

[0037] The steam discharge guide 15 may include a U-shaped adhesive portion 21 that is attached to a steam hole 14 formed on the front surface of the container 11 in the shape of a U rotated 180 degrees, a steam discharge non-adhesive film 22 that forms the internal space of the U-shaped adhesive portion 21, and a steam discharge port 23 located downward from the opening of the U-shaped adhesive portion 21.

[0038] The steam discharge guide 15 can be attached in such a way that one side is attached to a non-adhesive film and the other side covers the steam hole 14 with the steam hole 14 in the center, in accordance with the size of the outer casing of the U-shaped adhesive portion 21 which has double-sided adhesive properties.

[0039] Furthermore, the steam discharge guide 15 can be formed by attaching a steam discharge non-adhesive film 22 to the outer surface of a U-shaped adhesive portion 21 that has adhesive properties on one side, and the surface of the steam discharge non-adhesive film 22 that is in contact with the steam hole 14 can be formed in a non-adhesive state.
