Description

  The present invention relates to a gas range top plate cover and a method for manufacturing the same, and more particularly to a gas range top plate cover having a flat top plate other than the burner portion and a method for manufacturing the same.

  In recent years, in order to make it easy to wipe off dirt in a gas range, a flat top plate of the gas range is increasing. Various gas range top plate covers that are installed on the top plate of such a gas range and prevent the top plate from being soiled have been proposed (for example, Patent Document 1 and Patent Document 2).

  However, the top plate covers for gas ranges disclosed in Patent Document 1 and Patent Document 2 can be used for only one type of gas range. That is, since only one type of opening corresponding to the gas burner is formed, when installed in a gas range of another model, for example, a gap is generated between the opening and the gas burner to prevent the top plate from being stained. I couldn't.

  In view of this, there is a case in which an opening auxiliary line by a perforation is formed to form another opening so as to correspond to a plurality of types of gas ranges (Patent Document 3). However, in such a gas range top plate cover, dirt such as boiled juice infiltrates from the surface through the perforations, and the top plate cannot be prevented from being stained.

  In order to solve such a problem, there is one in which the opening auxiliary line described above is formed by a ruled line.

  FIG. 7 is a plan view showing a schematic shape of the top plate cover for the gas range disclosed in Patent Document 4, and FIG. 8 is an enlarged cross-sectional view of the VIII-VIII line shown in FIG.

  With reference to these drawings, the sheet body 61 constituting the top plate cover 60 has a rectangular sheet shape in which an aluminum foil 64, which is a kind of metal foil, is attached to the upper surface of a non-combustible paper 63 via an adhesive. have. The seat body 61 is formed with a first opening 65, a second opening 66, and a third opening 67 corresponding to each of a plurality of gas burners located in a gas range of a specific model. A ruled line 71 is formed around the first opening 65 at a size and a position corresponding to the opening of a gas burner of a gas range of another model. Further, a ruled line 72 is formed outside the ruled line 71 in a size and a position corresponding to the opening of the gas burner of another type of gas range. As shown in FIG. 8, the ruled lines 71 and the ruled lines 72 are formed in a linear shape by pressing the sheet main body 61 from above. Note that ruled lines are also formed around the second opening 66 and the third opening 67 in the same manner as around the first opening 65.

  In such a top plate cover 60, for example, in the case of a model in which the outer shape of the ring plate of the gas burner corresponding to the first opening 65 corresponds to the ruled line 71, by cutting the inner part with respect to the ruled line 71, A large opening can be formed in the sheet main body 61 instead of the first opening 65. Depending on the model having different openings, it is possible to form a larger opening in the sheet main body 61 by cutting out the inner part with the ruled line 72 as a reference.

  FIG. 9 is a schematic perspective view showing a use state of the top plate cover shown in FIG.

  Referring to the drawing, in use, first, when the size of the outer periphery of the ring plate 41 of the first gas burner 36 of the gas range 33 to be used does not match the size of the first opening 65, the ruled line 71 or the ruled line 72 is used to form a new large opening. The second gas burner 37 and the second opening 66 are similarly adjusted, and the third gas burner 38 and the third opening 67 are similarly adjusted. In the gas range 33 shown in the figure, each of the first gas burner 36, the second gas burner 37, and the third gas burner 38, and the first opening 65, the second opening 66, and the third opening of the top plate cover 60 are provided. It is not necessary to form another opening to match each of 67.

  When the top plate cover 60 is installed with respect to the top plate 35 in such a state, gaps between the ring plates 41 of the first gas burner 36, the second gas burner 37, and the third gas burner 38 are formed. It can be lost. Further, as described above, the ruled line 71 and the ruled line 72 are formed in a linear shape by pressing the sheet main body 61 from the upper surface, so that dirt such as boiled juice permeates the back side through the ruled line 71 and the ruled line 72. That is, there is no risk of entering the top plate 35.

  However, in such a top plate cover 60, since the ruled lines 71 and the ruled lines 72 made of dents are formed, it is easy to collect dirt in the dents and it is not easy to remove the dirt in the dents.

  In order to solve such a problem, there is a paper in which a slit which is an opening auxiliary line is formed only on the non-combustible paper located on the back side.

FIG. 10 is an enlarged cross-sectional view of another gas range top plate cover disclosed in Patent Document 4. As shown in FIG.
Referring to the figure, the configuration of sheet main body 61 made of non-combustible paper 63, adhesive layer 69 and aluminum foil 64 is the same as top plate cover 60 shown in FIG. However, in the top plate cover 80, a cut 85 is formed in the non-combustible paper 63 instead of the ruled lines 71 and the ruled lines 72 that are auxiliary opening lines formed in the top plate cover 60 shown in FIG. 7. Therefore, by opening the nonflammable paper 63 and the aluminum foil 64 together with the cut 85 as a reference, an opening having a predetermined size can be easily formed. Further, since the cut 85 is formed only on the non-combustible paper 63 side so as not to reach the aluminum foil 64, the upper surface of the aluminum foil 64 becomes flat, and the dirt can be easily wiped off. Furthermore, there is no possibility that the broth or the like dropped on the upper surface of the aluminum foil 64 penetrates the back surface side of the sheet main body 61 through the cut 85.

JP-A-9-133368 Japanese Patent Laid-Open No. 9-292129 Japanese Utility Model Publication No. 2-147713 JP 2008-286517 A

In the gas range top plate cover 80 shown in FIG. 10 as described above, the thickness T ₁ of the incombustible paper 63 formed by papermaking is determined by the basis weight, and the thickness T ₁ of the incombustible paper 63 is the entire surface thereof. It is difficult to be constant over the period. Therefore, in the processing using the ring-shaped Thomson blade, there is a problem that it is difficult to form a cut with a stable depth only on the non-combustible paper 63. This will be described below with reference to the drawings.

  FIG. 11 is a schematic cross-sectional view showing problems in the top plate cover shown in FIG.

  First, referring to (1), the cut 86 formed in the top plate cover 81 reaches the inside of the aluminum foil 64 with the tip thereof exceeding the noncombustible paper 63. With such a cut 86, there is a possibility that the sheet main body 61 is inadvertently separated by a slight force.

  Next, referring to (2), the cut 87 formed in the top plate cover 82 has a tip that slightly reaches the inward side of the incombustible paper 63. That is, since the portion where the cut 87 is formed is extremely shallow, it becomes difficult to form another opening in the sheet body 61 using the cut 87 as an opening auxiliary line.

  As described above, when the cut is directly formed on the non-combustible paper 63, many defective products are generated, and the yield of the product is lowered.

  Next, referring to (3), in the top plate cover 80 shown in FIG. 7, one surface of the noncombustible paper 63 is exposed to the outside. Therefore, as indicated by a two-dot chain line in the figure, the non-combustible paper 63 is warped by heat and moisture from the gas range, and a gap is generated between the installed top plate and the sheet main body 61. Therefore, the upper surface of the top plate cannot be stably covered, and there is a possibility that dirt may enter from this gap. This problem is caused by insufficient shape retention of the top plate cover 80.

  The present invention has been made in order to solve the above-described problems, and has a top plate cover for a gas range that has excellent shape retention and can easily form a cut as an auxiliary opening line. An object is to provide a manufacturing method.

  In order to achieve the above object, the invention according to claim 1 is a gas range top plate cover for covering a top plate of a gas range having a plurality of gas burners, which is on the upper surface side on both sides of the paper.

Formed into The first cut and the second cut have overlapping portions in a part of the circle including each, the opening corresponds to the overlapping portion, and the third cut is the first cut and the second cut It is formed around the cut.

  If comprised in this way, since both surfaces of paper will be covered with metal foil, shape retention property will improve and the inductivity of opening formation by a cut will be stabilized. Further, the formation position of the end of the cut is allowed by the thickness of the paper. Regardless of the type of gas range, the opening is always necessary.

  The invention according to claim 2 is the structure of the invention according to claim 1, and is formed around the third cut, and is of a type different from those of the first cut, the second cut and the third cut. A fourth cut for further forming another opening corresponding to the gas range is further provided.

  If comprised in this way, another opening can be formed further.

  According to a third aspect of the present invention, in the configuration of the first or second aspect of the present invention, a silicon coat is applied to the outer surface of the first metal foil.

  FIG. 1 is a plan view showing a schematic shape of a gas range top plate cover according to a first embodiment of the present invention, and FIG. 2 is an enlarged sectional view taken along line II-II shown in FIG. 3 is an enlarged view of a portion X shown in FIG.

  Referring to these drawings, the sheet main body 11 constituting the top plate cover 10 is attached to the entire surface of the non-combustible paper 51 and the non-combustible paper 51 via the adhesive layer 52 as shown in FIG. A first aluminum foil 53 that is a first metal foil, and a second aluminum foil 55 that is a second metal foil attached to the entire lower surface of the non-combustible paper 51 via an adhesive layer 54, It has a rectangular sheet shape. In this embodiment, the entire outer surface of the first aluminum foil 53 is printed with heat-resistant ink, but printing is not always necessary.

Further, non-combustible paper 51 of thickness _{T 1} is one having a basis weight of 100 g / ^{m 2} is used, the basis weight preferably ranges from 70~300g / ^{m 2.} Further, the second aluminum foil 55 is its thickness _{T 2} are used those 20 [mu] m, preferably ranges from 7～50Myuemu. The first aluminum foil 53 has the same shape as the second aluminum foil 55.

  In this way, both surfaces of the non-combustible paper 51 of the sheet main body 11 are covered with the first aluminum foil 53 and the second aluminum foil 55 having shape retention. Therefore, the moisture absorption of the non-combustible paper 51 is suppressed, and the shape retention of the sheet body 11 is improved. As a result, warpage due to heat and moisture from the gas range can be suppressed, so that the top plate can be fitted.

  A first opening 15 and a second opening 16 corresponding to a gas burner located on the front side of the gas range of a specific model are formed on the front side of the seat body 11 (lower side in FIG. 1). Further, a third opening 17 corresponding to a gas burner located at the rear of the gas range is formed at the rear of the seat body 11. Further, a cut line 18a is formed around the first opening 15 at a size and position corresponding to the opening of the gas burner of another type of gas range. A cut 19a is formed at a size and position corresponding to the opening of the gas burner. As shown in FIG. 3, the cut 19a is continuously formed in the second aluminum foil 55 and a part of the non-combustible paper 51, and the same applies to the cut 18a.

  Further, around the second opening 16, there are cuts 18b corresponding to the openings of the other gas burners of the other types of gas ranges described above, and openings of the other gas burners of the other types of gas ranges described above. Corresponding cuts 19b are formed. Similarly, cuts 18 c and 19 c are formed around the third opening 17. Accordingly, for example, in the case of a model in which the outer shape of the ring plate of the gas burner corresponding to the first opening 15 corresponds to the cut line 18a, the sheet body 11 is broken based on the cut line 18a, thereby replacing the first opening 15 with a large size. An opening can be formed in the sheet body 11. At this time, as described above, the cut 18a is continuously formed in the second aluminum foil 55 and a part of the non-combustible paper 51. Therefore, the sheet body 11 can be easily broken based on the cut 18a. That is, for example, when the cut line 18a is continuously formed on the second aluminum foil 55, the non-combustible paper 51, and a part of the first aluminum foil 53, as in the conventional example shown in FIG. The sheet body 11 is inadvertently cut off with a slight force. For example, when the cut line 18a is formed only in a part of the second aluminum foil 55, the cut line 18a is extremely shallow with respect to the sheet body 11 as in the conventional example shown in FIG. The sheet body 11 is difficult to break. Accordingly, the cut line 18 a needs to be formed in at least the second aluminum foil 55 with respect to the second aluminum foil 55 and the noncombustible paper 51. As a result, the cut line 18a has an appropriate depth with respect to the sheet body 11.

  In the case of the model corresponding to the cut 19a, as in the above-described formation of the opening by the cut 18a, a larger opening can be easily formed by breaking the sheet body 11 based on the cut 19a. Similarly, other openings can be easily formed in the cut lines 18b, 18c, 19b, and 19c. That is, since the inductivity of opening formation by the cut lines 18a to 18c and 19a to 19c is stabilized, other openings can be easily formed. Therefore, usability improves.

  Further, ruled lines 25 a, 25 b, 26 a, and 26 b are formed inward at a predetermined distance along the outer periphery of the top plate cover 10. As shown in FIG. 2, these are formed into a line by pressing the sheet body 11 from the upper surface. As a result, the bending rigidity of the outer peripheral portion of the top plate cover 10 is improved, and warping during use and curling in the opposite direction are prevented. In this embodiment, the portion surrounded by the ruled lines 25a, 25b, 26a and 26b is set to a size corresponding to the upper surface of the top plate of the gas range to be used. The reason for this will be described later.

  Further, cutting portions 49a to 49d are formed between corner portions on the outer periphery of the sheet body 11 and corner portions of the ruled lines 25a, 25b, 26a, and 26b. As a result, it is possible to easily bend the portions on the outer side of the ruled lines 25a, 25b, 26a, and 26b up and down along these.

  Next, a method for manufacturing the top plate cover 10 will be described, particularly focusing on the formation of the cut lines 18a to 18c and 19a to 19c.

  FIG. 4 is a schematic process cross-sectional view showing a method for manufacturing the top plate cover shown in FIG.

  First, referring to (1), the sheet body 11 is prepared in which the first aluminum foil 53 and the second aluminum foil 55 are attached to both surfaces of the non-combustible paper 51 described above.

  Next, referring to (2), the tip end of the ring-shaped Thomson blade 31 is approached from the outer surface side of the second aluminum foil 55 located on the lower surface side of the sheet body 11, that is, from the lower side.

  Next, referring to (3), the tip of the approached Thomson blade 31 reaches between the inner surface 58 of the second aluminum foil 55 and the inner surface 59 of the first aluminum foil 53 located on the upper surface side. To make a cut.

  Next, referring to (4), after the cut 19 is formed, the Thomson blade 31 shown in (3) is retracted downward. Then, the formation of the cut 19 where the tip is located between the inner surface 58 of the second aluminum foil 55 and the inner surface 59 of the first aluminum foil 53 is completed.

As described above, while the thickness T ₁ of the noncombustible sheet 51 has its entire surface hardly becomes constant, since the second aluminum foil 55 is formed by a rolling process, the thickness T ₂ are the entire surface substantially It is formed uniformly. Further, in the step shown in (3), for example, when the tip of the Thomson blade 31 was set to reach the center of the noncombustible sheet 51, the leading end position of the Thomson blade 31 of each of the upper and lower only T _1/2 minute error Is absorbed, that is, allowed up and down by the thickness T ₁ of the non-combustible paper 51. Therefore, the cut 19 can be easily and reliably formed, and the product yield is improved.

  Next, the usage form for the gas range of the top plate cover shown in FIG. 1 will be described.

  FIG. 5 is a schematic perspective view showing a use state of the top plate cover shown in FIG.

  Referring to the drawing, in use, the outer portion of the ruled line 25a is bent upward, and the outer part of each of the ruled lines 25b, 26a, 26b is bent downward.

  In this embodiment, the first opening 15 matches the outer periphery of the ring plate 41 of the first gas burner 36, and the second opening 16 matches the outer periphery of the ring plate 43 of the second gas burner 37. The third opening 17 matches the outer periphery of the ring plate 45 of the third gas burner 38. Therefore, it is not necessary to form a new large opening using the cut line, but when installing for a gas range different from this embodiment, according to the size of each gas burner of the gas range, What is necessary is just to use it in the state which formed the other opening using the cut.

  In this state, the top plate cover 10 is installed on the upper surface of the top plate 35 in a state where the respective virtues 40 are removed from the first gas burner 36, the second gas burner 37, and the third gas burner 38. At this time, the portions surrounded by the ruled lines 25a, 25b, 26a, and 26b are set to have a size corresponding to the upper surface of the top plate 35, and thus are bent downward at the outer portions of the ruled lines 25b, 26a, and 26b. The outer frame of the top plate 35 is surrounded by the portion. Further, the portion bent upward at the outer portion of the ruled line 25 a serves as a partition between the top plate 35 and the grill exhaust port 47, and the broth or the like dropped on the top plate cover 10 is grilled exhaust port 47. To prevent intrusion.

  In this way, since the top plate cover 10 is installed with respect to the top plate 35, there are no gaps between the ring plates 41, 43, and 45, and the upper surface thereof is in a flat state without unevenness. Easy wiping. In addition to improving the shape retention of the top plate cover 10 described above, the ruled lines 25a, 25b, 26a, and 26b can prevent warping in the outer periphery and curling in the opposite direction. Furthermore, since not only the upper surface of the top plate 35 but also the outer frame on the outer periphery thereof is covered with the top plate cover 10, it is possible to prevent the portion from being attached with dirt.

  FIG. 6 is a plan view showing a schematic shape of a gas range top plate cover according to a second embodiment of the present invention.

  In the top plate cover 20 according to this embodiment, the shapes of the first opening 15, the second opening 16, and the third opening 17 and the cut lines 18a to 18c and 19a to 19a in the top plate cover 10 shown in FIG. Since it is the same except the formation position of 19c, it demonstrates centering on the difference.

  Referring to the drawing, the first opening 27 formed on the front side of the seat main body 11 is an opening corresponding to the gas burner that is the object of the first opening 27 as shown in FIG. Instead, it is formed so that at least a part thereof corresponds to the target gas burner. That is, an overlapping portion of a circle including each of the cut line 21 and the cut line 22 corresponding to gas burners of different gas ranges (a circle that is the smallest opening in use) is punched as the first opening 27. In addition, cuts 23 and 24 corresponding to gas burners of other types of gas ranges are formed around the cuts 21 and 22. The second opening 28 and its periphery are also formed in the same manner as the first opening 27 and the cuts 21 to 24. In the third opening 29, the circle that is the minimum opening as described above is positioned so as to be surrounded by all the circles that are the other openings (circles that are cut). Therefore, as in the first embodiment, the third opening 29 is an opening that corresponds to the target gas burner.

  In such a top plate cover 20, the first opening 27, the second opening 28, and the third opening 29 are necessarily required openings regardless of the type of the gas range. That is, since an unnecessary opening is not formed, any type of gas range can be reliably handled. Further, since each of the first opening 27, the second opening 28, and the third opening 29 is used as a reference, the other openings can be easily formed by using the cut lines 21 to 24, so that the top plate cover can be formed. Twenty efficient uses are realized. In addition, it cannot be overemphasized that it is the same as that of 1st Embodiment about the effect in the breaks 21-24.

  In each of the above embodiments, there are three openings formed in the seat body, but the openings are formed in accordance with the number of burners of the gas range to be used. May be one place or other plural places. Alternatively, the openings may not be formed and all may be formed by opening auxiliary lines.

  Further, in each of the above embodiments, a plurality of cuts are formed around the opening, but the cut is formed in accordance with the type of the target gas range, and there is one cut. What is necessary is just to form above.

  Furthermore, in the above embodiment, the outer peripheral dimension of the seat body is formed larger than the upper surface size of the top plate of the gas range, but it may be the same as this size. In that case, there may be no ruled lines and cut portions formed on the outer periphery.

  Furthermore, in each said embodiment, although aluminum foil is used for a sheet | seat body, it replaces with this and you may use another metal foil.

  Furthermore, in each of the above-described embodiments, the non-combustible paper is used for the sheet body. However, flame retardant paper or the like may be used instead depending on the application.

  Further, in each of the above embodiments, the cut is formed by the Thomson blade, but the cut may be formed by a blade or a method other than the Thomson blade.

  Further, in each of the above embodiments, the outer surface of the first aluminum foil is printed with the whole surface heat-resistant ink, but instead of this, a silicon coat may be applied to the outer surface. In this case, since the smoothness of the outer surface of the first aluminum foil is improved, the removal of dirt by wiping becomes easier.
