Description

Portable Cookware Being Made of Paper

The present invention relates to a portable cooking container based on paper.

When cooking outdoors in a culture that has a high proportion of broth dishes, various sizes of cooking vessels are required, and various idea products for reducing or storing a plurality of cooking utensil sets have been developed.

One of the most common portable cooking utensils is Coppel, which minimizes the volume by making various sizes of containers and placing the remaining small containers in the largest order. However, the weight of the Coppell is 2-3kg, which is a burden when traveling for a long time, and after use, it has to be washed every time.

In recent years, products made of pots using paper have been released, which makes it lighter and can be discarded after use, eliminating the burden of washing (Application No. 20-2007-0016949).

However, the principle that this paper pot does not burn is the phenomenon that water loses heat before the paper reaches its ignition point, which blocks more water and paper pots when a mucus-like food such as eggs sticks to the floor. It is impossible to take away the heat of the paper and eventually the bottom of the pot burns. In this way, the bottom is burned due to an unexpected variable, so the material is paper, so there is a limitation that food is leaked immediately.

When the bottom burns out due to the strong sticky food material, problems occur in the coating liquid. Conventional paper pots use polyethylene as the coating liquid. Because the melting point of polyethylene is 106 ℃, the coating liquid is higher than the boiling point of water. It is unlikely to elute, but once the floor is burned, the possibility of polyethylene mixing with food cannot be ruled out.

In case of such a safety defect, even if it is not a big problem when used for personal use or for experimentation in schools, it is difficult to use in a restaurant that uses a variety of food ingredients or in a market that distributes products in large quantities, and thus the sales market is large. There is a problem of shrinking.

In addition, the conventional paper pot is to form a square pillar by folding a flat paper bar, if the pot is made large and contains a lot of water, the pot is limited due to the limitation that there are only four parts fixed to the side to form the pot shape It can't keep its shape and twists.

In general, a heating device has a circular flame shape, and in a rectangular pot, the distance from the vertex portion to the flame is different from the edge distance from the flame so that it is difficult to evenly heat the plate and reduce the size of the bottom of the pot. In order to reduce the size of the sides to prevent the flame from rising to the side, the corners should be referred to as the base, which makes the problem larger than necessary by subtracting the distance from the center to the corner to the edge. have.

If the pot is made large, the bottom of the paper is made of four pot holders pressurizing the bottom of the pot, so the hardness is weak, so when the weight of the water is added, the bottom falls or the position and angle of the pot is not reached. As a result, there is a problem that the torsion phenomenon as a whole. In the case of three pedestals, the instability becomes greater.

 In addition, the conventional paper pot is too large to be folded and fixed in the process of folding and flattening the paper of the plane so that the end portion is close to the bottom. In this case, when the water boils, the water between the paper and the paper There is also a problem leaking out.

The main purpose of the present invention developed to solve such a problem is to reduce the weight and volume to maximize portability, while overcoming the limitations inevitably caused by using a weak paper material, and using a weak hardness material. This is to solve the structural instability that occurs when manufacturing a square pillar shape.

The present paper pot proposed to achieve the above object in forming a coating layer by first forming a polyethylene coating layer on the inside of the container, and by further forming a coating layer of heat resistant silicone, PET, aluminum foil, etc., Even if the floor burns in an unexpected situation, it is characterized by blocking the possibility of coating liquid mixed with food due to high heat.

In addition, by designing a safety auxiliary container separately, attached to the lid portion or devised a safety auxiliary container that can also function as a lid, and in the case of sticky food materials such as eggs, it transforms into a thin stem shape in the process of entering the pot through this auxiliary container. It is added, or by heating while holding in the auxiliary container, the food is characterized by blocking the bottom of the fire and the bottom of the food by blocking the bottom of the water and pot.

The safety auxiliary container is made of cylindrical shape, but the bottom or side part is made to make a hole for water, water vapor or heat to pass through and protrudes a part of the side surface so that the protruding part is inserted into the uneven part of the hole on the lid side. It is characterized in that it can be fixed by moving to the left or right at a static height.

The safety auxiliary container is also made of a hexagon to enlarge the size of the six wings at the top to serve as a lid, or to expand the function to steamer, fondue, water bath, etc. by growing the container portion containing food. It is characterized by.

In addition, the basic idea is to form the shape of the body into a hexagonal column shape, and the ground plane that is bent inward at each vertex by the method of three-dimensional paper of the plane into a right triangle with the angle of 30 °, 60 °, 90 °. By forming the side and bottom at right angles, protruding the upper part of the ground plane into a proper shape and inserting the protrusion into the fixing hole of the side, or enclosing the side to be used as a device for fixing each side. It features. At this time, the vertical angle of the side can be adjusted by increasing or decreasing the inner angle of the vertex by 30 °.

The side of the body is a space in which a double wall portion formed by bending a hexagonal assembly in a state in which a portion of the upper portion is folded out of the primary portion reinforces the strength of the side surface and inserts a fixing device or a close contact device to connect the surface to the surface. It is characterized by using as.

In addition to the hexagonal shape of the container, it is injected into the mold press while forming a pleat on the side of the flat paper, or the pulp is directly injected into the mold press, and the lid made by combining the safety auxiliary container with the body made of a general pot shape. It is characterized in that the conversion to a disposable paper pot of a new function.

The portable paper pot of the present invention configured as described above provides an effect of protecting food more safely in case of emergency by reinforcing a coating having enhanced heat resistance and strength.

By changing the shape of the container from square to hexagon and expanding the range of application of the lid, it is possible to use the safety aid container to cook a wider variety of food.

By transforming the shape of the container from square to hexagon and improving the device to fix the side, it provides a stronger container effect.

By devising a versatile functional lid, it can be applied to existing disposable products to extend its function.

As described above, the existing paper pots are more stably and variously utilized, thereby providing an effect of greatly expanding the market of disposable paper pots.

It is a coating type section.

As shown in FIG. 1, the portable paper pot 100 of the present invention is divided into a lid 110 and a body 120. When the six corner portions are fixed by folding the developed view of FIG. Can be formed.

In forming the body 120, when the inside of the paper is coated with only polypropylene, the wall is fixed by simply fusion by applying heat to the places where the coating layers face each other 126a at the upper end of the three-dimensional grounding part 126. But, in the case of silicone, PET, aluminum foil can not try to bond by heat, the bonding in the following method.

3 is an enlarged view of the coupling part 121 of FIG. 1, and thus, a method of fixing the wall with the exploded view of FIG. 7 will be described. In the developed view, six reinforcing welding parts 127 form an inverted triangle, Fold the two triangular parts on the basis of the common fold of the three-dimensional ground part 126b and fold them in the direction of the container. 126c is also bent inward, and as shown in Fig. 3, the three-dimensional ground portion 126 of the right triangle shape is immediately set up. At this time, it should be noted that the three-dimensional ground portion 126 is bent to the inside of the container. Subsequently, as shown in FIG. 3, the folded contact device 125 of FIG. 7 surrounds the three-dimensional grounding part 126 and is folded inward, and the two insertion type fixing devices 123 are pushed into the side fixing holes 122. Insertion type fixing device 123 that comes out of the container is put under the reinforcing welding portion 127 folded out (127a)

As shown in Figure 1 and Figure 2, the lid 110 has six auxiliary trapezoidal wings rounded in a regular hexagonal shape and the auxiliary installation hole 111 made by making a cutting line, and the auxiliary installation hole stopper when installing the auxiliary ( Slide each wing under 112 to make a large hexagonal hole. Before closing the lid, the lid acts as one handle. When closing the lid, the other handle 128 passes through the handle and the hole 113. When the lid is fixed, the handle is folded outward. .

5, 6, and 8 are diagrams showing the structure and construction method of the safety auxiliary container 130. Here, folding the safety auxiliary container three-dimensional grounding unit 136 and folding the insertion type fixing device 133 into the fixing hole 132 while raising the side vertically is similar to when making the body of the pot, as shown in FIG. As described above, the three-dimensional ground portion 136 is folded out of the container. In addition, in the process of inserting the insertion-type fixing device 133 to the fixing hole 132, the container hanger 137 is bent in the direction perpendicular to the outside to form a shape as shown in FIG.

This safety auxiliary container 130 is mainly designed for viscous protein foods such as eggs, characterized in that the hole 139 is drilled at the bottom of the container. Taking eggs as an example, if the whole egg is broken when boiling ramen etc., even though the water is boiling, it sinks to the bottom in a lump and solidifies by heat while being attached to the bottom of the pot, thereby blocking the water and the bottom of the pot. However, when the water boils, stir while stirring the egg into the safety auxiliary container 130, the egg falls into a thin stem shape through the hole to harden by heat before reaching the bottom to protect the bottom of the pot.

Figure 9 is a perspective view of a second embodiment of a portable paper pot, Figure 10 is a perspective view showing the process of coupling each component, the body 220 of the pot is inserted into the high-tight device 224 protruding upwards and fixed therein Insertion type fixing device 223 is inserted into the hole 222 to first connect the wall surface of the pot, and by inserting the auxiliary frame 210 again to hold the shape of the pot more firmly, and finally used as a safety aid container The lid 230 is inserted to show that the completion.

Auxiliary frame 210 is made of a sub-frame coupling body 211 that can pass through the insertion-type fixing device 223 and the handle passage hole 213 that can pass through the handle 228.

Figure 11 shows a perspective view of the lid for the safety auxiliary container 230, Figure 14 shows a development view, the structure and molding process is similar to the safety auxiliary container 130, but the cover 231 is large The difference is that the lid-body coupler 237 and the lid-handle coupler 238 are made at the same time as it can cover the entire pot.

 As shown in the perspective view of the body 220 of FIG. 12 and the exploded view of FIG. 13, the stereoscopic grounding part 226 is bent inward to move the insertion type fixing device 223 into the fixing hole 222 and the insertion type of the handle 228. The body can be simply formed by inserting into the fixing hole 222 of the fixing device 233.

Figure 15 is a perspective view of a third embodiment of a portable paper pot, with the steamer-safety aid 310 installed in the body 220 and the auxiliary frame 210 shown in the second embodiment.

As shown in the perspective view of Figure 15 and the exploded view of Figure 16, the steamer-safety container 310 is a portion of the cover 231 while expanding the space for containing the contents in the safety cap container 230 of the second embodiment At the same time to transform into a form of auxiliary frame (210) is equipped with a separate lid 311, and a lid fixing wing 312 is attached to the periphery of the lid when closing the lid at right angles to insert it into the container to fix the lid to the container And, by attaching the steamer lid handle 313 separately to serve as a function to prevent excessive increase in the internal vapor pressure. Holes are also made in the bottom 239 and the side walls 239a to facilitate the circulation of steam and heat.

FIG. 17 is a perspective view of a fourth embodiment 400 of a portable paper pot, the overall structure of which is similar to the first embodiment 100, but shows another coupling manner in the coupling portion 421. Looking at the coupling method together with the exploded view of FIG. 18, the insertion type fixing device 423 connected to the top of the three-dimensional grounding part 126 passes through the fixing hole A 422a and comes out to the fixing hole B 422b. 425 wraps around the upper end portion of the insertion type fixing device 423 extending out of the fixing hole B 422b, and pushes it into the gap from the lower end of the reinforcing ground portion 427 to fix it.

19 is a view illustrating a principle of flat folding a hexagonal portable paper pot, wherein 400a is a perspective view showing a six sidewalls of a body part being folded in and a lid over it, and the plane of FIG. After the three-dimensionalized in the development of the folding back to the inside of the container to explain the principle of minimizing the folding of the side wall 426 as possible in the process of minimizing the volume to a flat shape as follows.

 In the drawing of 400b, the line of the three-dimensional ground portion side 426a and the side wall side edge (b) are drawn separately for ease of explanation, but this portion is an edge portion which is originally attached to each other. In the process of three-dimensionally container, two interconnected three-dimensional grounding part 126 should be in close contact with each other, but in order to fold the container into a plane, the three-dimensional grounding part 126 should be attached to the sidewall A 426a in a state where the two-dimensional grounding part 126 is extended. When the two side walls 426a and 426b are folded in at the same time with the side walls attached, the two side walls are folded about 90 degrees toward the bottom, and there is no need to make any side walls in the process. The principle of this is that the angle 426d between the solidified ground side edge 426a and the bottom side edge 426c and the angle between the sidewall side edge 426b and the bottom side edge 426c are all equal to 30 °. Because. That is, when the two side walls are folded in at the same time, it means that the three-dimensional ground portion side edge 426a and the side wall side edge 426b can be folded in a flat shape even though they are connected to one corner. Thus, all six sidewalls of a portable paper pot can be folded into a flat shape, like a 400c, without creating a single folding line. However, if the two-dimensional grounding unit 126 is folded without being unfolded for the convenience of the user, a folding line may be made only on two of the six side walls. Note that this is only possible if the bottom of the container is squared.

Figure 20 is a perspective view of the fifth embodiment, the body of the container 520 is formed by the injection molding at a time using a mold in a shape with a handle, the lid 510 is made of a special structure to adjust the height It is characterized by mounting the possible safety auxiliary container (530).

Safety auxiliary container 530 has a function to adjust the height at the same time while connecting the two and the body 533 is a hole 534 and a hole 534 on the bottom and at the same time while holding the container on the lid handle The connecting leg 532 is composed of three parts.

The lid 510 has a safety auxiliary container coupler 511 at the center thereof, and the coupling hole has an indentation groove 512 into which the connecting leg 512 of the safety auxiliary container 530 is fitted into an uneven shape. In addition to the steam outlet 513 and the lid-handle combination port 514 is composed.

FIG. 23 shows the shape of the safety aid container 530 as far as possible to engage the lid 510, and FIG. 24 shows the shape of the safety aid container as lowered and coupled to the lid from 543 and 544. Grab it and show it.

Figure 25 shows the principle that the safety container is put on the lid in a high position, when looking at the enlarged portion 546 of the connecting leg 532 portion of the safety aid container on the lid (546a, 546b), first the safety assistant It can be seen that if the container is rotated about 30 degrees counterclockwise in the raised state until the stratified portion of the connecting leg 532 is visible (546a), the stratified portion is caught out of the guide groove 512 and is covered by the lid (546b). ).

At this time, if the safety auxiliary container is installed high can be used for unpacking eggs, and if it is installed low, it can be used for cooking to contain various seafood or other sticky ingredients. For this reason, use a metal material that is harmless to the human body, such as aluminum, or, if it is made of paper, coat it with silicon. In addition, additional grooves in the middle of the connecting legs allow for more height adjustment.

Figure 26 shows an example of a coating method according to the present invention. The coating solution uses silicone 601, which is heat resistant and harmless to the human body, but the silicone cannot be directly bonded to natural paper, so that the coating is first coated with polyethylene (LDPE) 602 on the paper surface, and then the silicone (601) on it. ) Apply the coating.

In addition to silicone, polyethylene terephthalate (PET) 603 is a product that is harmless to the human body and has excellent strength. PET is directly heat-sealed onto paper 604 or on paper 604 coated with 602 primary LDPE coated PET, already produced in paperboard, to be heated by lamination.

In addition to the method of coating on paper, we propose a portable pot that combines heat and pressure resistant aluminum with high tensile strength paper to take advantage of both materials. By laminating 50 ~ 80μm-thick aluminum and paper using LDPE, it is possible to make portable paper pots that can be folded and unfolded while cooking more stably with various kinds of ingredients such as bag stew, seafood soup, hot pot and soup. As a result, the range of application of the product can be expanded.

Aluminum coating can be done on the inside of the paper or both inside and outside. When the aluminum is coated on the outside, the fast heat conduction effect of aluminum also warms the bottom of the paper pan evenly, improving the heating efficiency inside the container and making the paper more stable. There is an advantage to protect.
