Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple pot that can be disposable after use.

[0002]

2. Description of the Related Art In recent years, simple pots such as paper pots and metal foil pots have been used in place of earthen pots. This is because the simple pot has the advantages that it is easier to handle than a clay pot and that it can be discarded as it is after use.

According to this conventional technique, a paper pot is housed in a ceramic receiving container, and a ceramic weight is placed in the paper pot. Therefore, the shape of the paper pot is held by the receiving container, and the state in which the paper pot is housed in the receiving container can be maintained by the weight made of ceramics. In particular, the paper pot has a soft material and low thermal conductivity, and the main body does not become hot during use. Therefore, even if the paper pot is accidentally touched, the fingers and the like are not cut, and the burn is less likely to occur, which is excellent in safety. Furthermore, after use, it can be discarded as it is and incinerated, which is excellent in processability. In addition, the paper pot has a sense of quality due to its material and has a design. In addition, if characters or the like are printed on the paper, the design will be further improved.

Further, Japanese Utility Model Publication No. 4-41323 proposes a simple pot of metal foil. Since the simple pot is made of a metal foil sheet, it can be molded into a desired shape by, for example, deep drawing, and the shape is retained after molding. Therefore, a simple pot made of metal foil can be used without using a net, a saucer, etc. if it is formed into a shape that can be supported by the stove when placed on the stove. there were. Further, since the metal foil pan has excellent water retention, water or the like placed in the metal foil pan does not leak out.

[0005]

However, the above-mentioned conventional disposable pot has the following problems. That is, the conventional paper pot may absorb water during use and cause water leakage, or the paper may become transparent to impair the design. In addition to this, the conventional paper pot cannot hold the shape of the pot by itself when it is used, and in order to stably place it on the heating stove, separate equipment such as a saucer and a net is required. It was what I needed. Further, if water or the like placed in the paper pot during use evaporates, the temperature of the paper pot itself may rise and the paper pot may be burnt.

Therefore, in order to solve the above problems to some extent, the materials used for the paper pot are restricted, and it has been difficult to manufacture a wide variety of paper pots.
For example, in order to provide shape retention, water resistance and water retention, the base paper needs to be sand laminated with polypropylene, and the weight per unit area needs to be 100 g / m ² or more.

On the other hand, the simple pot of metal foil does not cause the above-mentioned problems in water resistance, water retention and shape retention. However, in the metal foil pan formed of the metal foil, there is a risk of cutting fingers and the like at the edge of the metal foil when handling the metal foil pan. Furthermore, since the metal foil pan has excellent thermal conductivity, it becomes hot and is easily burned when touched by mistake. Therefore, the metal foil pan has a problem in safety.

The present invention has been made in view of the above problems, and an object thereof is to maintain its shape without using a saucer, a net, etc. Shape retention, water resistance, without cutting
An object of the present invention is to provide a simple pot which is water-retaining and safe, and which allows the paper material used to have flexibility.

[0009]

In order to achieve the above-mentioned object, the invention according to claim 1 is to press-mold a composite in which a paper and a metal foil are adhered, and the inside is the paper, and the outside is the outside. The metal foil is arranged.

According to a second aspect of the present invention, in the first aspect, the metal foil changes its shape by an external force, and
It has the property of retaining its shape at least partially when the external force is removed.

[0011] The invention described in claim 3 is the invention according to claim 1 or 2.
In the above, the paper is a non-woven fabric composed mainly of fibers having thermocompression bonding properties, and a metal foil is combined with the non-woven fabric by thermocompression bonding.

[0012] The invention according to claim 4 is the invention according to claim 1 or 2.
In the above, the paper and the metal foil are combined by dry lamination. According to a fifth aspect of the present invention, in any one of the first to fourth aspects, the metal foil is an aluminum foil.

Therefore, according to the first aspect of the present invention,
A simple pot is formed by a composite of paper and metal foil bonded together. Therefore, since the paper is pasted on the metal foil, the edge portion of the simple pot is rounded. It is possible to prevent the fingers from being cut when handling the simple pot. Further, since the strength of the simple pot is increased by the metal foil, the paper placed inside does not need to have shape retention and water retention. in addition,
Water inside the simple pan is prevented from leaking out of the simple pan by the metal foil.

According to the second aspect of the present invention, in addition to the above-mentioned action, the metal foil on the outer side of the simple pot has a shape-retaining property, so even if water or seasoning is put in the simple pot, the simple pot is used. The shape of is reliably retained.

According to the invention of claim 3, claim 1
Alternatively, in addition to the function of the invention described in 2, the non-woven fabric mainly composed of fibers having thermocompression bonding property can be easily thermocompression bonded to a metal foil by applying heat pressure such as a heat calender roll, a heat embossing roll, or a heat press. It will be possible. Therefore, the non-woven fabric and the metal foil are bonded to each other without using an adhesive, and the manufacturing process can be simplified and the manufacturing cost can be reduced.

According to the invention of claim 4, claim 1
Alternatively, in addition to the function of the invention described in 2,
After EVA resin is extracted and laminated, the paper and the metal foil are laminated by a sand laminating method, and then pressure-molded to easily form a simple pot.

According to the invention described in claim 5, according to claim 1,
In addition to the effects of the inventions described in 4 to 4, since the metal foil is an aluminum foil, pressure molding is easy and shape retention is maintained.

[0018]

DETAILED DESCRIPTION OF THE INVENTION The first embodiment of the present invention will be described below.
Will be described with reference to FIGS. 1 to 3. (First Embodiment) The simple pot 1 in the present embodiment is formed and processed by a hot press. As shown in FIG. 1, the simple pot 1 has a substantially deep dish shape and includes a bottom portion 2 and a peripheral wall portion 3. The bottom portion 2 has a circular shape and is provided at the center of the simple pot 1 as shown in FIG. The periphery of the bottom portion 2 is a bent portion 5. The portion outside the bent portion 5 is erected,
The peripheral wall portion 3 has a substantially cylindrical shape. Further, a mounting portion 6 is formed inside the bent portion 5. As shown in FIG.
The mounting portion 6 is formed in an oblique shape from the bent portion 5 toward the center of the bottom portion 2.

The peripheral wall portion 3 has a shape in which its diameter is continuously increased from its lower portion to its upper portion. In addition, folds 4
Are formed along the entire surface of the peripheral wall portion 3 in the vertical direction.

The thermocompression-bonded composite material used as the material for the simple pan 1 in this embodiment has a two-layer structure as shown in FIG. That is, the non-woven fabric 7 is arranged inside and the aluminum foil 8 as a metal foil is arranged outside. The aluminum foil 8 has a thickness of 20 to 40 μm. The simple pot 1 of the present embodiment has heat resistance, moldability, shape retention after molding, due to the cooperation of the non-woven fabric 7 and the aluminum foil 8.
It has excellent waterproofness and food safety.

Further, in the present embodiment, the reason why the thickness of the aluminum foil 8 is set to 20 to 40 μm is firstly to have the strength capable of retaining the shape of the simple pot 1 after the molding process. This is for the purpose of providing 2 with sufficient water resistance, water retention and heat resistance. In the conventional metal foil pan, the thickness of the metal foil needs to be 50 μm in order to have a shape-retaining strength, but in this embodiment, since the strength is improved, the aluminum foil 8 should be formed thin. Is possible. Therefore, the manufacturing cost can be reduced.

As a nonwoven fabric having thermocompression bonding property, wood pulp (N-BKP) was adjusted to Cf600 (Canadian standard freeness) by a beater, and then copolyester composite fiber 2D
× 5 mm (in this form, the copolyester composite fiber used a core-sheath structure in which core = regular polyester 1D and sheath = modified polyester 1D) was mixed in a ratio of 1: 9, and then mixed in a round net paper machine. After adding chemicals such as defoaming agent and sticky agent, paper was made. Drying is performed at 125 ° C., which is 110 ° C. or more of the melting point of the sheath portion of the copolyester composite fiber by a drum dryer, and the weight per unit area is 20 g /
After creating the thermocompression bonding nonwoven m ^2, a thickness of 20~40μ
A temperature of 130 ° C, speed of 5 m / min, pressure of 20 kg / cm using a thermal calender for aluminum foil of m.
^It was thermocompression bonded at ² .

Further, as the wetting / strengthening agent, a polyamide epichlorohydrin-based resin in which 0.5% is internally added is used. By internally adding the wetting and strengthening agent, the nonwoven fabric 7 can maintain sufficient strength even when it absorbs water during use.

Further, as shown in FIGS. 1 to 3, in the simple pot 1 of this embodiment, the nonwoven fabric 7 is formed inside the simple pot 1 and the aluminum foil 8 is formed outside the simple pot 1. . Here, the surface of the non-woven fabric 7 corresponding to the inner surface of the simple pot 1 is not subjected to size treatment and is in a sizeless state. This is because when the surface of the nonwoven fabric 7 is sized and made smooth, moisture does not penetrate into the nonwoven fabric 7 and the nonwoven fabric 7 is in a state of containing air during heating. This is because when the simple pot 1 is heated in such a state, the temperature of the nonwoven fabric 7 containing air rises, and the nonwoven fabric 7 may be burnt.

Next, a method for manufacturing the simple pot 1 having the above structure will be described. First, the above-mentioned non-woven fabric 7 to which the wetting and strengthening agent is internally added is thermocompression-bonded to the aluminum foil 8 to form a thermocompression-bonded composite having a two-layer structure.

Next, the composite is cut into a predetermined shape. In this embodiment, the composite is cut into a 24 cm square. Then, the cut composite is set in a hot press mold. Then, this is molded by pressing and holding it in the temperature range of 130 ° C. to 140 ° C. for 0.5 seconds. Since the non-woven fabric 7 has thermoplasticity and softens in the above temperature range, the composite is formed into a shape corresponding to the mold.

After molding, the simple pot 1 is cooled to room temperature when taken out from the mold. As a result, the non-woven fabric 7 and the aluminum foil 8 are retained in the shape at the time of molding. In this embodiment, the molding process is performed at an optimum molding temperature of 135 ° C.

The operation of the simple pan 1 of the present embodiment having the above configuration will be described. FIG. 3 shows a usage state of the simple pan 1 in the present embodiment. As shown in the figure,
The simple pan 1 is placed on the heating stove 9. At this time, the placing portion 6 is located slightly outside the upper end of the heating stove 9, and the simple pan 1
Is placed stably.

Although water, cooking material (not shown) or the like is stored inside the simple pot 1, since the simple pot 1 of this embodiment has a large strength as described above, the shape can be maintained even in such a case. it can.

The solid fuel 10 is placed on the bottom plate 9b of the heating stove 9. When cooking using the simple pan 1, the solid fuel 10 is burnt to burn the bottom portion 2 of the simple pan 1.
Heat. Here, since the bottom portion 2 is constantly cooled by the water in the simple pot 1, it is not heated to 100 ° C. or higher. Further, since the surface of the non-woven fabric 7 is not subjected to size treatment, the non-woven fabric 7 is in a state of absorbing water.

The non-woven fabric 7 in contact with water in the simple pot 1 absorbs the water. Even in such a case, this non-woven fabric 7
As mentioned above, since the moistening agent is internally added to the
There is no problem that the strength of the non-woven fabric 7 is lowered and the shape of the simple pot 1 is not retained.

In addition, in the simple pot 1 of this embodiment, the nonwoven fabric 7 is used.
Since it has a two-layer structure of the aluminum foil 8 and the aluminum foil 8, the sharpness at the edge of the simple pot 1 is relaxed and slightly rounded.

Further, the simple pot 1 is formed by hot pressing. That is, in the simple pot 1 according to this embodiment, the aluminum foil 8 has a shape-retaining property. According to the manufacturing method of the simple pan 1 described above, when hot-pressing a plurality of thermocompression-bonded composites, the nonwoven fabrics 7 are located between the composites, and the materials are hard to fit together.

Further, since the pleat 4 is formed on the peripheral wall portion 3, the design of the simple pot 1 is improved. Further, it is possible to print designs such as pictures and letters on the non-woven fabric 7. The effects of the simple pot 1 in the present embodiment having the above configuration will be described.

(1) Since the simple pan 1 is provided with the aluminum 8 on the outside, it has high strength and excellent shape retention. Therefore, the paper 7 does not have to have the shape-retaining property, the degree of freedom in the material of the paper 7 is increased, and various types of materials can be used to manufacture a wide variety of simple pots. Further, there is no possibility that the simple pot 1 will be deformed by the weight of water or cooking material and fall into the heating stove 9, and it is not necessary to use a saucer, a receiving net or the like.

(2) Since the aluminum foil 8 has a shape-retaining property, a simple pot can be formed into a desired shape. (3) Even if the non-woven fabric 7 in contact with the water in the simple pot 1 absorbs the water, the non-woven fabric 7 retains the strength of the non-woven fabric 7 because the wetting and strengthening agent is internally added to the non-woven fabric 7 as described above. Has been done. Further, even if the non-woven fabric 7 inside the simple pot 1 absorbs water, the water does not leak to the outside of the aluminum foil 8, and the simple pot 1 has improved water resistance and water retention.

(4) Since the sharpness at the edge of the simple pot 1 is relaxed and slightly rounded, there is no danger of cutting fingers or the like at the edge during handling and it is safe. (5) Since the surface of the non-woven fabric 7 is not subjected to size treatment, the non-woven fabric 7 absorbs water and the bottom 2 is not burnt.

(6) According to the method for manufacturing the simple pan 1 described above, the simple pan 1 excellent in shape retention, water resistance, water retention and heat resistance can be easily manufactured. (7) When hot-pressing a plurality of thermocompression-bonded composites, since the nonwoven fabric 7 is located between the composites, the simple pans 1 can be easily removed after the processing. Therefore, the working efficiency is improved, and eventually the manufacturing cost of the simple pot 1 can be reduced.

(8) Since the pleat 4 is formed on the peripheral wall portion 3, the design of the simple pot 1 is improved. Also, since it is possible to print designs such as pictures and letters on the non-woven fabric 7,
The design of the simple pot 1 will be improved.

Next, another embodiment of the present invention will be described focusing on the part different from the first embodiment. (Second Mode) The second mode is the first mode as shown in FIG.
In the same shape as the above-mentioned form, 70% of polyolefin-based composite fibers (core = polypropylene, sheath = polyethylene) and 30% of wood pulp (N-BKP) are used in place of the non-woven fabric 7 composed mainly of copolyester composite fibers. A non-woven fabric 7 (weight per unit area: 30 g / m ² ) was used.

Then, the polyolefin-based composite fiber as the non-woven fabric 7 having thermocompression bonding is used for the aluminum foil 8 (thickness 30 μm) as the metal foil by using a heat calender and the temperature is 140 ° C. and the pressure is 20 kg / cm. ² speed 2
Thermocompression bonding was performed at 0 m / min. Further, the thermocompression-bonded composite is hot-pressed at a temperature of 130 ° C. for 0.5 hours.

It does not rise above 00 ° C. Therefore, since the non-woven fabric 7 inside the simple pot 1 is used at the softening point (130 ° C. or higher) of the polyolefin fiber or lower, it is not softened and is kept pressed to the aluminum foil 8. As described above, the non-woven fabric 7 is not peeled off from the aluminum foil 8 at the time of use, the design is maintained, and the shape is retained.

Also in the simple pot 1 of this embodiment, since the non-woven fabric 7 is arranged inside and the aluminum foil 8 is arranged outside,

Therefore, there is a degree of freedom in the material of the non-woven fabric 7 arranged inside the simple pot 1, and the fibers described below can be used as the non-woven fabric. The main fibers of the aluminum foil 8 and the thermocompression-bondable non-woven fabric 7 are polypropylene fiber, polyethylene fiber, polyvinylidene chloride fiber, polyamide fiber, polyester copolymer fiber,
There are various conjugate fibers and the like, and the non-woven fabric 7 can also be formed by using at least one kind of the fibers listed above.

Further, the structure of the non-woven fabric 7 is not limited to a single layer and may be two or more layers. In that case, of course, one surface of the plurality of layers has a heat sealing property, and the aluminum foil 8 is thermocompression bonded to the surface.

Since the non-woven fabric 7 is thermocompression-bonded to the aluminum foil 8 without using an adhesive, the amount of the main fibers (various heat-sealing fibers) mixed in the non-woven fabric 7 should be sufficient to obtain sufficient crimp strength. It must be at least 40% or more.

(Third Mode) As shown in FIG. 1, in the third mode, a pulp-rich paper is used in the same shape as that of the first mode, instead of the non-woven fabric 7 having the copolyester conjugate fiber as the main fiber. And aluminum foil as metal foil 8

Paper is 100% wood pulp (N-BKP)
And 0.5% of a polyamide epichlorohydrin resin as a wet paper strength enhancer are internally added, and the weight per unit area is 25 g / m ² . Then, the paper and the aluminum foil 8 (thickness 30 μm) were compounded by extrusion coating with polypropylene.

Further, the composite was hot-pressed at a temperature of 130 ° C. for 0.5 second to perform molding.
The simple pot 1 was manufactured so that the paper was placed inside and the aluminum foil 8 was placed outside.

Also in the simple pot 1 of the present embodiment, paper on the inside,
An aluminum foil 8 is arranged on the outer side to form a two-layer structure. Therefore, similar to the first and second embodiments, the aluminum foil 8 improves the strength, heat resistance, water retention and shape retention of the simple pot 1, and paper improves safety and design. There is. Therefore, there is a degree of freedom in the material of the paper placed inside the simple pot 1, and the fibers described below can be used as the paper. As the pulp-rich paper, vein fibers and bast fibers can be used, and specifically, softwood pulp, hardwood pulp, san tsubaki, manila hemp, prunus, goose bark, hemp, flax, sisal hemp and the like can be used.

Further, as described in the second embodiment, since water, cooking ingredients and the like are arranged in the simple pot 1, the simple pot is not always cooled and heated to 100 ° C. or higher. Therefore, if the resin that can be used for extrusion coating has a softening point of 100 ° C. or higher, the paper is aluminum foil 8
Since it does not peel off, low density polyethylene, polyolefin, high density polyethylene, polypropylene, ethylene, vinyl acetate copolymer and the like can be used.

In this embodiment, the degree of freedom in the materials of paper and resin is increased as described above, and it is possible to manufacture a wide variety of simple pots. (Fourth Embodiment) The fourth embodiment is based on the polyolefin-based composite fibers (core = polypropylene, sheath = polyethylene) 70% and wood pulp (N-BKP) 30% used in the second and third embodiments. A non-woven fabric 7 (weight per unit area: 30 g / m ² ) and pulp-rich paper are pressure-bonded to an aluminum foil 8 so that the simple pot 1 has a three-layer structure.
