Description

  The present invention relates to a cooking container provided with a print display layer, and in particular, in a print display layer constituting a part of a multilayer coating film, printing can be performed without causing bleeding and the like after finishing treatment. It is related with the container for cooking provided with the printed display layer which can be visually recognized well.

  In general, a cooking container made of aluminum or the like has a thermal stability and a coating film formed by applying a coating liquid mainly composed of a fluorocarbon resin (PolyTetraFluoroethylene: PTFE) on the inner surface thereof. Improves wear resistance.

  Currently, such cooking containers are manufactured by using various manufacturing methods such as changing the ratio of components contained in the coating liquid to be applied or changing the structure of the coating film. Among them, a method of forming a multilayer coating film by sequentially laminating a primer coat, a midcoat, and a topcoat, which are coating films, on the inner surface of a cooking container is the mainstream.

  Conventionally, as a technique for applying a water level gauge, scale, etc. (hereinafter referred to as “pattern”) to such a cooking container, a screen is formed on the upper surface of a coating film (for example, midcoat) constituting a part of the multilayer coating film. A technique for forming a print display layer by printing or pad printing is known. (See Patent Document 1)

JP 2008-036377 A

  However, in the printing method using the above screen printing or pad printing, the printing display layer is formed using a printing liquid mainly composed of a fluorocarbon resin having a low viscosity. As a result, there is a problem that a clear and elaborate (fine and elaborate) print display layer cannot be formed.

  In general, since each coating film constituting the multilayer coating film is based on black or dark gray, in order to display the pattern clearly, it is displayed in white which is a color contrasting with black or dark gray. It is preferable. However, when a printed display layer is formed simply by adding a white pigment to a fluorocarbon resin, a coating film (for example, a top coat) based on black or dark gray is laminated on the upper surface of the printed display layer. There is a problem that the printed display layer that is visually recognized through the film looks yellowish, and the printed pattern is difficult to see.

  The present invention has been made in order to solve the above-mentioned disadvantages, and an object of the present invention is to form a fine and elaborate print display layer in the printing process, and to perform print display even after finishing processing. Provided is a cooking container provided with a printed display layer capable of clearly viewing the layer.

  In the multilayer coating film formed by sequentially laminating a primer layer, a mid layer, and a top layer on a base material, the subject is a printed display layer provided on the upper surface of at least one of the mid layer or the top layer The printing display layer has a viscosity of 5000 to 7000 cps and is formed of a fluorocarbon resin containing at least one of a blue pigment and diamond particles. .

  As described above, in the above configuration, the print display layer constituting a part of the multilayer coating film is formed of a fluorocarbon resin having a viscosity of 5000 to 7000 cps. Here, when the viscosity of the fluorocarbon resin is less than 5000 cps, the fluorocarbon resin shifts from a soft liquid state to a liquid state. For example, pad printing using such a fluorocarbon resin is performed. In this case, it becomes difficult for the fluorocarbon resin to adhere to the pad surface, and it becomes difficult to form a clear and elaborate hue or pattern. Also in screen printing, bleeding or the like occurs in the printing process, making it difficult to perform good printing.

  On the other hand, when the viscosity of the fluorocarbon resin exceeds 7000 cps, the fluorocarbon resin tends to be highly tacky. When pad printing is performed using such a fluorocarbon resin, In some cases, the carbon resin is unevenly adhered to the pad surface. In such a case, since the fluorocarbon resin is partially attached to the mid layer or the top layer, it is difficult to perform good printing. Similarly, in the screen printing, the fluorocarbon resin is unevenly adhered, and it becomes difficult to perform good printing.

  Therefore, by adjusting the viscosity of the fluorocarbon resin to be in the range of 5000 to 7000 cps, it becomes possible to form a fine and elaborate print display layer on the upper surface of the mid layer or the top layer.

  In addition, the printed display layer that forms part of the multilayer coating film is made of fluorocarbon resin with durability and wear resistance, which improves the durability and wear resistance of the entire cooking container. Can be made.

  In the above configuration, the fluorocarbon resin forming the print display layer contains at least one of a blue pigment and diamond particles. For this reason, when a blue pigment is contained in a fluorocarbon resin based on white, the color of the entire fluorocarbon resin can be changed to light blue. When a coating film based on black or dark gray is laminated on the top surface of the fluorocarbon resin colored in this way, the color composition of light blue and black or dark gray is visually recognized through the coating film. It is possible to make the display color of the print display layer appear substantially white. Therefore, since the printed display layer provided on the upper surface of the mid layer or the top layer can be clearly seen, the aesthetics (visual effect) of the cooking container can be reliably improved.

  On the other hand, when diamond particles are contained in the fluorocarbon resin, heat transfer from a heating source such as fire to the cooking surface can be improved due to the heat conduction characteristics of the diamond particles.

At this time, the blue pigment is preferably contained in an amount of 3 to 5% by mass with respect to the total mass of the fluorocarbon resin. The “mass%” is a value obtained by converting the ratio of the mass of the contained substance to the mass of the entire fluorocarbon resin.
Here, when the blue pigment is less than 3% by mass with respect to the total mass of the fluorocarbon resin, the content of the blue pigment with respect to the fluorocarbon resin is very small, so that the fluorocarbon resin is based on white. The color of the fluorocarbon resin is still almost white. For this reason, as described above, when the print display layer is viewed with the naked eye through the coating film, the print display layer looks yellow, and the print display layer is difficult to see. On the other hand, when the content of the blue pigment exceeds 5% by mass with respect to the total mass of the fluorocarbon resin, the blue degree of the fluorocarbon resin becomes too strong, and the print display layer is interposed through the coating film. When it is seen with the naked eye, it looks blue as it is. In this case, since there is almost no difference in color contrast with the coating film based on black or dark gray, the printed display layer is difficult to see. Therefore, by adjusting the content of the blue pigment of the fluorocarbon resin to be in the range of 3 to 5 mass% with respect to the total mass of the fluorocarbon resin, it is applied to the upper surface of the mid layer or the top layer. Since it is possible to visually recognize the pattern more clearly, the aesthetics of the cooking container can be further improved.

  The diamond particles are preferably contained in an amount of 0.2 to 0.5% by mass with respect to the total mass of the fluorocarbon resin. Here, when the diamond particles are less than 0.2% by mass with respect to the total mass of the fluorocarbon resin, since the content of the diamond particles with respect to the fluorocarbon resin is very small, the heat conduction characteristics of the diamond particles. It is difficult to exert the effect effectively. On the other hand, if the content of diamond particles exceeds 0.5% by mass with respect to the total mass of the fluorocarbon resin, a large amount of diamond particles are contained in the fluorocarbon resin, resulting in a printed display layer and a mid layer. And adhesion to the top layer and the like are reduced. Therefore, the mid layer or the top layer is adjusted by adjusting the content of the diamond particles of the fluorocarbon resin to be in the range of 0.2 to 0.5% by mass with respect to the total mass of the fluorocarbon resin. The heat transfer from the heating source to the cooking surface can be reliably improved while maintaining the adhesion to the cooking surface.

  Further, the fluorocarbon resin is preferably composed of particles having an average particle diameter of 200 to 300 μm. Here, when the average particle diameter is less than 200 μm, for example, when screen printing is performed using such a fluorocarbon resin, the print display layer is formed to be thicker than necessary, and the mid layer or The adhesive strength of the printed display layer with respect to the top layer is reduced. On the other hand, if the average particle diameter is larger than 300 μm, printing tends to be impossible in screen printing, and even if a print display layer can be formed on the upper surface of the mid layer or top layer, printing The contour portion of the display layer cannot be clearly formed, and the quality of the cooking container is deteriorated. Furthermore, when the average particle diameter is larger than 300 μm, the print display layer tends to be formed thin. That is, even if such a printed display layer is formed in the multilayer coating film, it does not affect the thickness of the entire multilayer coating film, so that the durability and wear resistance of the entire multilayer coating film can be improved. Have difficulty. Therefore, by adjusting the average particle diameter of the fluorocarbon resin to be in the range of 200 to 300 μm, a printed display layer having a clear outline is formed while maintaining the adhesive strength to the mid layer or the top layer. This makes it possible to perform better printing.

  The print display layer is preferably formed by pad printing or screen printing. If comprised in this way, a printing display layer can be easily formed in the upper surface of a mid layer or a top layer.

  Furthermore, it is preferable that the multilayer coating film includes a finishing layer laminated on each of the top layer and the printed display layer provided on the top surface of the top layer. If comprised in this way, since the thickness of the whole multilayer coating film will increase, durability and abrasion resistance of a multilayer coating film can be improved reliably.

  The fluorocarbon resin preferably contains ceramic particles. According to this structure, since the ceramic particles have a large Mohs hardness, the strength of the printed display layer can be improved when a predetermined amount of ceramic particles is contained in the fluorocarbon resin. Therefore, the wear resistance of the entire multilayer coating film can be improved.

As described above, according to the cooking container provided with the print display layer according to the present invention, the print display layer can be satisfactorily formed in the printing process, and the print display layer is clear even after finishing processing. Therefore, it is possible to reliably improve the aesthetics (visual effect) of the cooking container.
Further, when diamond particles are contained in the fluorocarbon resin, heat transfer from a heating source such as fire to the cooking surface can be reliably improved.

It is sectional drawing of the container for cooking with which the multilayer coating film which concerns on embodiment of this invention was given. It is sectional drawing of the container for cooking in which the multilayer coating film which shows the modification of FIG. 1 was given. It is sectional drawing of the container for cooking in which the multilayer coating film concerning 2nd Embodiment was given. It is sectional drawing of the container for cooking which shows the modification of FIG.

Hereinafter, a first embodiment according to the present invention will be described with reference to FIGS. 1 and 2. It should be noted that members, arrangements, and the like described below do not limit the present invention, and it goes without saying that various modifications can be made in accordance with the spirit of the present invention.
FIG. 1 shows an embodiment of the present invention, and FIGS. 1 and 2 illustrate a cooking container provided with a printed display layer according to the present invention. FIG. 1 is a cross-sectional view of a cooking container provided with a multilayer coating film, and FIG. 2 is a cross-sectional view of a cooking container having a printed display layer showing a modification of FIG.

  As shown in FIG. 1, a cooking container 1 according to this embodiment is a container used for cooking food such as an inner pot such as a rice cooker, a pan, a frying pan, a hot plate, etc. And a multilayer coating film 100 formed on the upper surface of the substrate 110.

  The substrate 110 is made of, for example, aluminum or an alloy containing the same, and the surface thereof is roughened in advance by grinding, etching, sanding, or the like. Thereby, since the surface area of the base material 110 is increased, the adhesive force of the primer layer 120 described later to the base material 110 can be increased. The roughening of the substrate 110 may be performed in a state before processing and forming such as sheet metal or after processing and forming.

  The multilayer coating film 100 is formed on the cooking surface side of the cooking container 1, for example, a primer layer 120 laminated on the upper surface of the substrate 110, a mid layer 130 laminated on the upper surface of the primer layer 120, and a mid layer The printing display layer 150 is formed on the upper surface of the layer 130, and the top layer 140 is stacked on the upper surfaces of the mid layer 130 and the printing display layer 150. Each of these layers is formed using a material whose main component is a fluorocarbon resin (PTFE).

  The primer layer 120 is a coating film that forms the lowermost layer of the multilayer coating film 100 and is formed so as to be directly bonded to the surface of the substrate 110. That is, the primer layer 120 is a coating film to which heat from the substrate 110 heated from a heating source such as fire is first transmitted. For this reason, it is preferable to form the primer layer 120 by the fluorocarbon resin containing the component excellent in thermal stability.

  The primer layer 120 can be formed by, for example, spin, roller, air press coating or the like in a flat state before the substrate 110 is processed and formed, while the substrate 110 is processed and formed into a specific form. After that, for example, it can be formed by using a coating method such as spraying.

  The mid layer 130 is a coating film configured as an intermediate layer of the multilayer coating film 100. Like the primer layer 120, the mid layer 130 is, for example, a spin, roller, It can be formed by air press coating or the like. On the other hand, after the substrate 110 is processed and molded into a specific form, it can be formed by using a coating method such as spraying. At this time, it is preferable that the thickness of the mid layer 130 is formed to be approximately the same as the thickness of the primer layer 120.

  The printed display layer 150 is formed to display scales, characters, patterns and the like at predetermined positions of the cooking container 1 and is formed of a soft liquid fluorocarbon resin having a viscosity of 5000 to 7000 cps. ing. As described above, by adjusting the viscosity of the fluorocarbon resin to 5000 to 7000 cps, for example, even when the print display layer 150 is formed by pad printing or screen printing, the upper surface of the mid layer 130 is clear and elaborate. The print display layer 150 can be reliably formed. Such a viscosity can be measured by, for example, a Brookfield viscometer.

  The fluorocarbon resin is composed of particles having an average particle diameter of 200 to 300 μm. As described above, by adjusting the average particle diameter of the fluorocarbon resin to 200 to 300 μm, it is possible to form the printed display layer 150 having a clear outline while maintaining the adhesive strength to the mid layer 130. .

  The fluorocarbon resin forming the printed display layer 150 contains 3 to 5% by mass of a blue pigment such as phthalocyanine blue with respect to the total mass of the fluorocarbon resin, and diamond particles such as industrial diamond. Is contained in an amount of 0.2 to 0.5% by mass with respect to the total mass of the fluorocarbon resin. As described above, by adjusting the content of the blue pigment to 3 to 5% by mass with respect to the total mass of the fluorocarbon resin, the display color of the print display layer 150 that is visually recognized through the top layer 140 Can be shown as approximately white.

  Further, as described above, by adjusting the content of diamond particles to 0.2 to 0.5% by mass with respect to the total mass of the fluorocarbon resin, the adhesion to the mid layer 130 is maintained and the fire is maintained. The heat transfer from the heating source such as the cooking surface can be improved.

  Such a print display layer 150 can be formed by screen printing or pad printing as described above.

  The screen printing is a method in which an opening is formed in a flexible printing plate, and the soft liquid fluorocarbon resin is rubbed into the opening and printed on the cooking container 1.

  In pad printing, the fluorocarbon resin applied to a substantially flat plate is transferred onto a flexible pad surface, and the pad surface is pressed against a desired portion of the cooking container 1 for cooking. In this method, printing is performed on the container 1. Generally, the printing plate is formed of, for example, a copper plate or the like, and an etching groove (corrosion layer) for forming the printed display layer 150 is formed on the surface thereof at a depth of 20 to 100 μm.

  Here, since the printing plate including the etching groove may be corroded by the mucous fluorocarbon resin, at least the etching groove has, for example, electroless nickel or the like so that the thickness becomes 20 μm or less. It is preferable to perform plating by. By applying such plating, corrosion of the etching groove is prevented and the strength of the etching groove itself is increased. For this reason, even when the printing is repeatedly performed by pad printing, the depth of the etching groove can be maintained to some extent. Furthermore, damage or deformation of the edge of the etching groove that occurs when an impact is applied from the outside can be suppressed. For this reason, it becomes possible to print the outline part of a pattern clearly by using the printing plate in which the said plating was given especially.

  In the present embodiment, the fluorocarbon resin constituting the printed display layer 150 contains both the blue pigment and the diamond particles. However, the present invention is not limited to this, and only one of them is contained in the fluorocarbon resin. It is also possible.

  The top layer 140 is a coating film that is formed as the uppermost layer of the multilayer coating film 100. Like the primer layer 120 and the mid layer 130, the top layer 140 is, for example, spin-shaped in a flat state before the substrate 110 is processed and formed. On the other hand, after the base material 110 is processed and molded into a specific form, it is formed by a coating method such as spraying.

  Moreover, in the top layer 140, after performing the coating process by such a coating method, baking and a cooling process are performed. Accordingly, the top layer 140 is permanently deformed in a strong and stable state, and can be formed in a film (thin film) shape on the upper surfaces of the mid layer 130 and the print display layer 150. In addition, although only the coating process was performed in the primer layer 120 and the mid layer 130, after performing a coating process similarly to the top layer 140, you may perform a heat processing and a cooling process.

  The top layer 140 is closely fixed to the upper surfaces of the mid layer 130 and the printed display layer 150, and the outer surface thereof is formed substantially flat along the inner surface shape of the cooking container 1. Thus, when the outer surface shape of the top layer 140 is made substantially flat, it is necessary to form the top layer 140 with a large thickness over the entire region where the print display layer 150 is formed. That is, the thickness of the entire multilayer coating film 100 inevitably increases, so that the durability and wear resistance of the multilayer coating film 100 can be improved.

  The top layer 140 is not limited to the case where the outer surface is formed to be substantially flat. For example, as shown in FIG. 2, the top layer 140 has a shape of the outer surface of the print display layer 150 formed so as to protrude upward from the upper surface of the mid layer 130. It is also possible to form an uneven shape along.

  In this way, by making the outer surface of the top layer 140 concavo-convex corresponding to the part where the printed display layer 150 is formed, not only the scales, characters, patterns, etc. can be seen with the naked eye, but also directly by hand. Since it can also touch, it becomes possible to set it as the cooking container 1 which also satisfies a user's tactile sense (hand feeling). The print display layer 150 is formed in a frequently used portion of the cooking container 1, that is, a portion where the multilayer coating film 100 is heavily worn, and the top layer is formed along the outer surface shape of the print display layer 150. It is also possible to form the outer surface shape of 140 in an uneven shape. As a result, the thickness of only the heavily worn portion of the multilayer coating film 100 can be increased relative to the other portions, so that the amount of fluorocarbon resin used for the top layer 140 can be reduced. While suppressing, durability and abrasion resistance of the multilayer coating film 100 can be improved.

  The outer surface shape of the top layer 140, which is the uppermost layer, is not limited to the outer surface shape as shown in FIGS. 1 and 2, and the coating method employed when the top layer 140 is formed may be changed, Various shapes can be obtained by adjusting the amount.

  As described above, according to the cooking container provided with the print display layer according to the present embodiment, the print display layer 150 constituting a part of the multilayer coating film 100 is a fluorocarbon resin having a viscosity of 5000 to 7000 cps. It is formed by. As described above, by adjusting the viscosity of the fluorocarbon resin to 5000 to 7000 cps, even when the print display layer 150 is formed by pad printing or screen printing, a clear and fine print display is provided on the upper surface of the mid layer 130. The layer 150 can be reliably formed, and printing with a fine finish can be performed. Further, since the printed display layer is formed of a fluorocarbon resin having durability and wear resistance, the durability and wear resistance of the entire multilayer coating film 100 can be improved.

  Further, the fluorocarbon resin forming the print display layer 150 contains 3 to 5% by mass of a blue pigment with respect to the total mass of the fluorocarbon resin, so that it can be visually recognized through the top layer 140. The display color of the printed display layer 150 can be viewed as substantially white. Therefore, since the pattern provided on the upper surface of the mid layer 130 can be clearly displayed, the aesthetics (visual effect) of the cooking container can be reliably improved.

  Furthermore, since the fluorocarbon resin forming the printed display layer 150 contains 0.2 to 0.5% by mass of diamond particles with respect to the total mass of the fluorocarbon resin, the adhesion to the mid layer 130 is improved. The heat transfer from the heating source such as fire to the cooking surface can be improved while maintaining the above. That is, for example, when the cooking container 1 containing water is heated by a heating source, after boiling in a region heated directly by a superheat source, it can be boiled in other regions around it in a relatively short period of time. Thus, cooking time can be shortened by adjusting the content of diamond particles.

  Since the fluorocarbon resin forming the printed display layer 150 is composed of particles having an average particle diameter of 200 to 300 μm, the contour thereof is maintained while maintaining the adhesive strength to the mid layer 130 as described above. The printed display layer 150 having a clear portion can be formed.

  Next, a second embodiment according to the present invention will be described with reference to FIGS. FIG. 3 is a sectional view of a cooking container provided with a multilayer coating film according to the second embodiment, and FIG. 4 is a sectional view of a cooking container showing a modification of FIG. The second embodiment shown in FIG. 3 and FIG. 4 is different from the first embodiment in that the print display layer is formed on the top surface of the top layer, and each of the top layer and the print display layer. The only difference is that a finishing layer is laminated on the upper surface of the substrate, and the other components are the same as those in the first embodiment, and therefore, the same numbers are assigned and redundant description is omitted.

  As shown in FIG. 3, the multilayer coating film 200 formed on the top surface of the substrate 110 includes a primer layer 120, a mid layer 130, a top layer 140, and a printed display layer 250 formed on the top surface of the top layer 140. And a finishing layer 260 laminated on the top surface of each of the top layer 140 and the printed display layer 250.

  The print display layer 250 is formed of a fluorocarbon resin having a viscosity of 5000 to 7000 cps, similar to the print display layer 150 described in detail in the first embodiment. It is composed of particles having a diameter of 200 to 300 μm (see FIGS. 1 and 2). Further, the fluorocarbon resin contains 3 to 5% by mass of a blue pigment with respect to the total mass of the fluorocarbon resin, and diamond particles have a content of 0.2% with respect to the total mass of the fluorocarbon resin. To 0.5% by mass. As in the first embodiment described above, the fluorocarbon resin constituting the print display layer 250 can contain only one of a blue pigment and diamond particles.

  The finishing layer 260 is a coating film formed as the uppermost layer of the multilayer coating film 200, and is formed by, for example, spin, roller, air press coating or the like in a flat state before the substrate 110 is processed and molded. On the other hand, after the base material 110 is processed and molded into a specific shape, it is formed by a coating method such as spraying.

  The finishing layer 260 is tightly fixed to the upper surfaces of the top layer 140 and the printed display layer 250, and the outer surface thereof is formed substantially flat along the inner surface shape of the cooking container 1.

  Note that the finishing layer 260 is not limited to the case where the outer surface is formed to be substantially flat, but as shown in FIG. 4, the finishing layer 260 follows the outer surface shape of the printed display layer 250 formed to protrude upward from the upper surface of the top layer 140. It is also possible to form an uneven shape.

  As described above, according to the present embodiment, the print display layer 250 is formed on the top surface of the top layer 140, and the finish layer 260 is additionally formed on the top surfaces of the top layer 140 and the print display layer 250. The entire thickness of the multilayer coating film 200 can be increased. For this reason, since the thickness of the multilayer coating film 200 is increased in comparison with the first embodiment, the durability and wear resistance of the multilayer coating film 200 can be further improved.

  In the above-described embodiment, the fluorocarbon resin forming the print display layers 150 and 250 contains a predetermined amount of blue pigment or diamond particles. However, for example, other components such as ceramic particles can also be contained. It is. Here, since the ceramic particles have a large Mohs hardness, the strength of the printed display layers 150 and 250 can be improved when a predetermined amount of the ceramic particles is contained in the fluorocarbon resin. The wear resistance of the entire coating films 100 and 200 can be improved.

  According to the present invention, it is possible to print neatly in the printing process, and the printed display can be clearly seen even after finishing processing. It can be used for various cooking containers having a display layer.
