Description

[0001] Portable Cooker [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a portable cooking utensil, and more particularly, to a portable cooking utensil using a heat generating body that generates heat by reacting with water as a heat source.

When outdoor activities such as mountain climbing, fishing, etc. are carried out, portable cooking utensils are used to cook food.

Gas, charcoal, electricity and the like conventionally used as a heat source of a portable cooking vessel have disadvantages such as inconvenience of transportation, risk of fire occurrence, limitation of use place, etc. Recently, a heating element, which generates heat by reacting with water, A portable cooking container to be used is being used.

FIG. 15 is an exploded perspective view of a conventional portable cooking vessel, FIG. 16 is an exploded perspective view of a conventional portable cooking vessel, and FIG. 17 is a longitudinal sectional view of a conventional portable cooking vessel.

The conventional portable cooking utensil includes an outer container 110, a fastening means 140 coupled to the outer container 110, and a fastening means 140 coupled to the outer container 110 through the fastening means 140, A container lid 130 provided on the upper side of the content container 120 and a safety valve 151 and a vapor discharge valve 152 provided on the outer container 110 one by one.

The outer container 110 has a concave outer container body 111 and an outer container flange 112 bent outward from the upper end of the outer container body 111.

The fastening means 140 includes a bracket 141 coupled to a side upper end of the outer container body 111, a pair of bands 143 coupled to the bracket 141 through the pivot pin 142, A locking protrusion 145 coupled to one end of the other of the bands 143 and a loop 146 coupled to the locking lever 145 .

Each of the bands 143 is formed in a cross-sectional shape.

The content container 120 includes a concave inner container body 121, a content container flange 122 formed outwardly from the top of the container body 121, A closed skirt portion 123 formed in the space between the side of the content medium body portion 121 and the content medium skirt portion 123, And has a packing member (124).

The container unit packing member 124 is formed of an elastic material such as silicone rubber.

The content container 120 having the above-described configuration is installed so that the content container flange 122, the content container skirt portion 123 and the content container packing member 124 enter the diagonal sectional groove of the band 143, The mounting state of the holding member 120 is maintained by the engagement action between the ring 146 and the locking projection 144. [

A heating element accommodating space is provided between the bottom surface of the container body 121 and the bottom surface of the outer container body 111 in a state where the container 120 is installed, And is disposed on the upper side of the flange 112.

The container lid 130 has a lid portion 131, a sealing rib 132 formed on the bottom surface of the lid portion 131, and a lid handle 136 formed at the center of the upper surface of the lid portion 131.

The container lid 130 having the above-described configuration is configured such that the lid part 131 covers the opening area of the container body 121 and the sealing rib 132 contacts the top of the inner surface of the container body 121 Respectively.

The safety valve 151 is configured to automatically open when the steam pressure of the outer vessel 110 exceeds a predetermined value. The safety valve 151 having such a configuration is well known in the art and its detailed description is omitted.

The steam discharge valve 152 is configured to automatically open when the steam pressure of the outer vessel 110 exceeds a predetermined value. The steam discharge valve 152 having such a configuration is well known in the art, and thus a detailed description thereof will be omitted.

A method of cooking food using the conventional portable cooking vessel having the above-described configuration will be described below.

First, the food to be cooked is placed in the container 120.

Next, the heating element 1201 and water are introduced into the bottom surface of the outer container 110. The heating element 201 can be manufactured by, for example, a method of incorporating a powder of a metal or a metal compound into the outer surface of a nonwoven fabric material capable of causing a hydration reaction in contact with water. Such a heating element 201 is well known in the art and its detailed description is omitted.

Next, using the fastening means 140, the contents container 120 containing the food is installed on the upper side of the outer container 110.

Next, the container lid 130 is installed so as to cover the opening area of the container body 121.

The food contained in the content container 120 is heated by the heat generated through the hydration reaction between the heating element 201 and water.

The steam pressure of the content container 120 and the outer container 110 is increased while the food contained in the content container 120 is heated (the water contained in the content container and the outer container is evaporated by the heating action of the heating element).

The vapor pressure of the content container 120 can be kept constant since the vapor discharge valve 152 is automatically opened when the vapor pressure of the content container 120 exceeds a predetermined value.

On the other hand, when the steam pressure of the outer container 110 rises excessively due to a malfunction of the steam discharge valve 152, the safety valve 151 operates to prevent the outer container 110 from exploding.

When the cooking is completed, the steam discharge valve 152 is manually operated to discharge the steam inside the outer vessel 110. [

However, according to the conventional portable cooking container, the hermeticity between the container lid 130 and the container 120 is lowered due to the inelastic contact between the sealing rib 132 and the inner surface of the container 120, There is a problem that it is long. Since the heat generation time of the heating element 201 is short, if the cooking time of the food is long, there arises a secondary problem that the food to be cooked is limited.

Since the container lid 130 is not constrained to the container 120 (the fastening means tightens the container between the container and the outer container), the airtightness between the container lid 130 and the container 120 is lowered The container lid is less likely to be caught by the vapor pressure of the content vessel during cooking).

A related prior art document is Korean Patent Registration No. 10-0917694 (registered on September 9, 2009, entitled Portable Cooking Container Heated with Exothermic Fume), which includes a conventional portable cooking container Is disclosed.

Accordingly, it is an object of the present invention to provide a portable cooking container which is improved in hermeticity of a container lid and a contents knob, and which is capable of fastening a container lid and a contents container as well as fastening an outer container and an inner container by using one member .
