DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a stove cover laid on a top plate of a gas range installed in a system kitchen or the like.

[0002]

2. Description of the Related Art For example, a gas range incorporated in a system kitchen has a large number of burners such as three or four and a top plate is formed of a single large plate. As a means for preventing stains, oil stains, and the like due to boiling over, disposable stain prevention mats made of aluminum foil are well known.

[0003] The dirt prevention mats include a type that integrally covers the entire upper surface of the top plate and a type that is divided and used for each burner.
It has a thickness of about 0 μm or more, and is integrally formed by die molding (drawing).

[0004] However, it is difficult to manufacture without wrinkles or the like, so that it is not easy to manufacture and there is an inconvenience that damage is likely to occur during transportation.

[0005] Therefore, aluminum foil is flame-retardant because it is easy to manufacture as compared with an integrally molded product, and can be folded or rolled up in a cylindrical shape during transportation or storage so that it is not bulky and easy to handle. It has been considered that a cover is formed by a flexible rectangular sheet formed by lining paper or noncombustible paper, and an opening as a burner exposure hole is formed in the sheet.

[0006]

However, the fact that the sheet has flexibility is that, on the other hand, an opening as a burner exposure hole is provided along the periphery of the opening formed on the top plate side. If the sheet is difficult to hold in shape and the sheet opening is simply cut out in a circular or elliptical shape, a gap is created between the sheet opening and the top plate, from which boiled juice flows to the back of the sheet. And flows over the top plate.

Therefore, the peripheral edge of the opening of the sheet is raised upward along the rising wall of the peripheral edge of the opening on the top plate side, or a mountain-shaped ridge is provided near the opening so as to bulge upward. Although it is considered to provide a protruding portion formed by forming the sheet, there is a problem that a sheet having flexibility is easily broken and therefore difficult to form.

An object of the present invention is to solve the above-mentioned disadvantages of the prior art, and to form a cover with a flexible rectangular sheet formed by backing flame-retardant paper or non-combustible paper on aluminum foil. It is possible to reliably prevent outflow of boiling water and the like out of the sheet from the opening as the formed burner exposure hole or the periphery of the sheet, and furthermore, the sheet is formed by lining the aluminum foil with paper as described above. An object of the present invention is to provide a stove cover for a gas range that can form a rising portion that can prevent the outflow of boiling water or the like without breaking the periphery of the opening even if it is easy to use, and also has excellent shape retention.

[0009]

In order to achieve the above object, the present invention firstly provides a stove cover laid on a top plate of a gas range, which is a flexible cover formed by lining paper with aluminum foil. A substantially circular opening as a plurality of burner exposure holes is formed in a square sheet having properties, and the periphery of the opening is raised up in a conical shape obliquely upward to form a wavy inclined portion, and the periphery of the sheet is formed. The gist of the invention is that a rising portion that can be bent is formed at the portion via a bending curve.

Second, a stove cover laid on a top plate of a gas range, which is a flexible square sheet formed by lining paper with aluminum foil and having a plurality of burner exposure holes as a plurality of burner exposure holes. Forming a circular opening,
The periphery of the opening is raised conically obliquely upward to form an inclined portion, the upper portion of the inclined portion is bent, and a projecting portion extending substantially horizontally is formed at the upper end of the inclined portion through the bent portion. ,on the other hand,
In the peripheral portion of the seat, a rising portion that can be bent through a folding curve is formed, or in addition to this configuration, reinforcing ribs are provided at intervals so as to straddle the inclined portion and the protruding portion. It is the gist.

Third, in addition to the first or second configuration, the inclined portion is formed at an inclination angle of 20 to 30 degrees, or the paper is flame-retardant paper or non-combustible paper; Alternatively, the gist is to provide a water-repellent layer on at least the paper around the opening, or to laminate an aluminum foil on the other surface of the paper.

According to the first aspect of the present invention, since the sheet has the flexibility formed by backing the aluminum foil with the paper, the sheet can be easily mounted on the top plate of the stove. In addition, it is not deformed by heat. Because the periphery of the substantially circular opening serving as the burner exposure hole is raised obliquely upward in a conical shape to form an inclined portion, and a bendable rising portion is formed at the periphery of the sheet via a folding curve. In addition, it is possible to reliably prevent the broth from flowing out of the sheet.

Further, although the sheet is easy to break, the inclined portion can be formed by bending to form the inclined portion by raising the periphery of the opening obliquely upward in a conical shape to form the inclined portion, thereby breaking the sheet. It is possible to form a rising part which can prevent the outflow of the boiling juice and the like.

[0014] In addition, by forming the inclined portion in a wavy shape, the shape retention of the sheet can be further ensured.

According to the second aspect of the present invention, in addition to the above-described operation, the shape of the peripheral portion can be maintained by providing the inclined portion and the substantially horizontal protruding portion around the opening of the sheet by the bent portion. Thus, restoration and deformation of the sheet can be suppressed, and shape retention can be ensured.

According to the sixth aspect of the present invention, in addition to the above-mentioned functions, the water-repellent layer can prevent moisture from penetrating into the paper when the broth or the like flows out from the opening to the back surface of the sheet. Restoration and deformation can be prevented.

According to the present invention, in addition to the above-described functions, it is desirable to use flame-retardant paper or non-combustible paper as the paper, but by laminating an aluminum foil on the other surface of the paper, Non-combustible paper such as kraft paper can be used because it can prevent the burning of paper, and is effective in preventing the breakage of the sheet during molding. It will be excellent.

[0021]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a plan view showing an embodiment of a gas range stove cover of the present invention. First, an example of a gas range in which a gas range stove cover of the present invention is used will be described with reference to FIG.

In the drawing, reference numeral 1 denotes a top plate of a multiple gas range having three burners, which is incorporated in a system kitchen or the like, and a circular opening 3 for exposing the burner 2 is formed by a triangle. A rising wall 5 that rises upward is formed around the flat portion 4 formed at the apex position of FIG.

The rising wall 5 rises substantially vertically from the flat portion 4 to form a rising portion 5a.
From the upper end of the horizontal part 5b, which becomes a supporting step of the virtue 6, is formed outward, and the outer edge of the horizontal part 5b is further raised to form a rising part 5c, and further from the upper end of the rising part 5c. A horizontal portion 5d extends outward. A grill exhaust port 7 is provided in the horizontal portion 5d located at the rear.

An upright wall 3a is usually provided on the periphery of the opening 3, and the outer periphery of the burner 2 is larger than the opening 3 extending outward from the upright wall 3a so that the boiling juice does not enter the opening. A cover ring 8 having a diameter is attached.

The gas stove cover 9 of the present invention is used for the top plate 1 of such a gas range.
A rectangular sheet provided with an opening 10 for exposing the burner 2 at a position corresponding to the opening 3 formed in the top plate 1
Form 11

Although the shape of the opening 10 is preferably circular, it may be formed in an elliptical shape so as to correspond to the burner 2 whose arrangement position is slightly different depending on the model.

The sheet 11, FIG. 3, the flame燃紙or noncombustible sheet 13 as the paper on the rear surface of the thin aluminum foil 12 of approximately 6~40μm as the material as shown in FIG. 10 for example Tsuboryo 70~150g / m ² Alternatively, non-combustible paper 23 such as kraft paper is bonded and backed with an adhesive 14 to form a sheet having flexibility. Flame-retardant paper or non-combustible paper 13 is formed by applying aluminum hydroxide solution to paper as water-absorbing paper, or immersing paper in this solution, and adhesive 14 having heat resistance. For example, an acrylic resin is used.

An opening 10 having a diameter of 80 to 110 mm is formed in such a sheet 11, and the periphery of the opening 10 is raised conically in an obliquely upward direction so that the inclination angle α from the sheet 11 does not exceed 30 degrees. A portion 15 is formed, and furthermore, a protrusion 17 that extends substantially horizontally is formed at an upper end of the inclined portion 15 through the bent portion 16 by bending the upper portion of the inclined portion 15.

Since the stove cover for a gas range is a disposable product, the thickness of the aluminum foil 12 and the basis weight of the paper need to be within the above ranges from the viewpoint of manufacturing cost. In addition, since it is used for a commercially available gas range, it is necessary to form the opening 10 for exposing the burner 2 to the dimensions described above,
The periphery of the opening 10 needs a rising part having a height of 3 to 5 mm from the flat surface of the sheet to prevent the outflow of the broth. However, since the sheet 11 formed in the above range is easily broken,
Although it is difficult to form the rising part by the drawing process in which a tensile force is applied as in the case of a conventional integrally molded product in which an aluminum foil 12 having a thickness exceeding 40 μm is used, the periphery of the opening 10 is formed in a conical shape. If the sheet 11 is raised obliquely upward, it can be formed by bending without applying a tensile force, so that the rising portion can be formed without breaking the sheet 11. In this case, it is also advantageous in forming that the opening 10 is made substantially circular so that the tearing stress is not applied to one point but is evenly applied in the circumferential direction.

When the periphery of the opening 10 rises obliquely upward on a cone, if the inclination angle exceeds 30 degrees, the sheet 11 is easily broken. Therefore, the upper limit of the inclination angle is desirably set to 30 degrees. The lower limit of the inclination angle may be about 10 degrees, but the height of the rising portion from the flat surface of the sheet needs to be 3 to 5 mm as described above to prevent the outflow of the broth, so the inclination angle is 20 degrees. If it is less than 30, the protrusion length of the rising portion must be increased, so that the lower limit of the inclination angle is preferably set to 20 degrees.

Then, as shown in FIG. 9, a water-repellent layer 18 is provided on at least the flame-retardant or non-combustible paper 13 or non-combustible paper 23 (not shown) around the opening 10. The water-repellent layer 18 is formed on the surface of the flame-retardant paper or the non-combustible paper 13 by using silicon, wax,
It is performed by coating with a water-repellent resin such as fluorine, generally, after coating the above-described water-repellent resin on flame-resistant paper or non-combustible paper 13 or non-combustible paper 23,
Laminated with aluminum foil 12.

As the material of the sheet 11, as described above, the aluminum foil 12 is made of a flame-retardant paper or a non-combustible paper 13 or a non-combustible paper.
It is not limited to the one backed by 23, but as shown in FIG.
It is also possible to laminate, without burning even when using non-combustible paper 23 such as kraft paper,
In addition, the restoration and deformation of the sheet 11 can be more effectively achieved, and the shape retention can be improved.

At the periphery of the sheet 11, a top plate 1
A fold curve 19a is provided corresponding to the transition position from the flat portion 4 to the rising portion 5a, and a first rising portion 20a that can be bent on four sides is formed by the fold curve 19a, and a substantially triangular shape is formed at a corner. A shape rising portion 21 is formed.

A folding curve 19 is formed at the first rising portion 20a of the four sides.
b, a first horizontal portion 20b extending outward is further extended so as to be freely bent, and a fold curve 19 is formed outside the first horizontal portion 20b.
c, the second rising portion 20c is extended in a freely bendable manner, and a second horizontal portion 20d is extended outside the second rising portion 20c by a folding curve 19d.

The connecting point between the first rising portion 20a of the four sides and the substantially triangular rising portion 21 at the corner and the rising portion 21 itself may or may not be provided with a bent curve. , Startup section
21 is to project outward during assembly.

In the method of forming the folding curve, for example, a sheet made of a material that is easily broken is formed by forming a crease by pressing, for example, to form a bending habit, and forming the bent portion 16 of the inclined portion 15 by bending. The sheet 11 can be processed without breaking the sheet 11 similarly to the inclined portion 15.

Further, of the second horizontal portions 20d formed on the four sides, those protruding from the rear grill outlet 7 are shortened so that the grill outlet 7 is not blocked.

The length of the first rising portion 20a located on the short side of the rectangular sheet 11 is formed longer than that of the long side, and the top plate 1 is slightly different depending on the model. Correspond to the dimension on the long side.

Next, the method of use will be described. When the product is displayed at a store, or when transported or stored, the inclined portion 15 is used.
Since the sheet 11 is formed, the sheet 11 is prevented from being rolled up in a cylindrical shape, and the sheet 11 is flattened as it is to form a plurality of sheets. In this case, the peripheral bent portion may be sold in a state where each part is bent along a bending curve and assembled in a dish shape and stacked, but may be sold in a stacked state in an unfolded state. Is also possible, in the latter case,
The user bends the periphery by himself.

The method of bending the peripheral portion is as follows.
The innermost folding curve 19a is bent inward, and first rising portions 20a are raised on four sides.

At this time, the rising portion 21 connected to the first rising portion 20a also rises. Therefore, when no folding curve is provided, the flexibility of the sheet 11 is utilized by utilizing the flexibility of the sheet 11. Protrude in a naturally curved state outward.

After the first rising portion 20a and the rising portion 21 are raised, the first horizontal portion 20b, the second rising portion 20c, and the four horizontal sides are further provided on the four sides via the folding curves 19b, 19c, and 19d. The sheet 11 is assembled into a dish shape by bending the second horizontal portion 20d.

When used at home, the stove cover 9 assembled in the same shape as the integrally molded product as described above.
Or after assembling the sheet 11 at home into a dish of the same shape as the integrally molded product, cover ring 8 and
The cooker cover 9 assembled in a dish shape is placed on the upper surface of the top plate 1 of the gas range, and the opening 10 is matched with the opening 3 of the top plate 1, and the burner 2 is removed from the opening 10. Reveal.

The top plate 1 of the stove cover 9
At the time of attachment to the stove, since the stove cover 9 is held in a dish-like state, the stove cover 9 can be used only by being placed on the top plate 1. In particular, since a substantially horizontal projection 17 is formed at the tip of the inclined portion 15 around the opening 10, even if the sheet 11 has flexibility, the stiffness becomes strong, and the strength against restoration and deformation is obtained. And the shape of the periphery of the opening 10 can be maintained in the formed shape.

In this state, as shown in FIG.
Of the opening 10 of the top plate 1 rises along the rising wall 3a around the opening 3, and a substantially horizontal projection 17 covers the upper edge of the rising wall 3a. In addition, the first rising portion 20a, the first horizontal portion 20b, the second rising portion 20c, and the second horizontal portion 20d in the vicinity are the rising portion 5a and the horizontal portion 5 of the top plate 1, respectively.
b, the rising portion 5c, and the horizontal portion 5d are placed on the upper surface corresponding to the positions thereof, and the rising portions 21 at the corners are located at the rising portions 5c.
It rises in a state where it protrudes outward at the corner between a and 5a.

Then, the cover ring 8 is mounted on the burner 2, and the virtues 6 are placed on the first horizontal portion 20b and the horizontal portion 5b. As a result, the first horizontal portion 20b is fixed to the horizontal portion 5b of the top plate 1 with the virtue 6, and the use state is stabilized.

Even if the length of the long side of the top plate 1 is slightly different depending on the model, the length of the first rising portion 20a on the short side of the stove cover 9 is increased. You can adjust it here.

Therefore, when used, the inclined portion 15 and the first rising portion 20a, the first horizontal portion 20b, the second rising portion 20c, and the second horizontal portion 20d of the four sides spill over the sheet 11. The broth or the like is prevented from flowing out of the sheet 11. In the event of a leak, the water repellent layer 18 can prevent moisture from penetrating into the flame-retardant paper or the non-combustible paper 13 or the non-combustible paper 23, and the restoration and deformation of the sheet 11 can be prevented.

Further, a non-combustible paper 13 or a non-combustible paper 23
When the aluminum foil 12 is further laminated on the other side of the paper, such as non-combustible paper 23, the combustion of the paper can be prevented even if the surroundings of the burner 2 becomes high temperature when using the gas range, and the sheet It is excellent by restoring and suppressing deformation, and shape retention is improved.

Further, since the sheet 11 is made of aluminum foil 12 which is lined with flame-retardant paper or non-combustible paper 13 or non-combustible paper 23 and has flexibility, it is possible to avoid damage during transportation.

FIG. 5 and FIG. 6 show a second embodiment,
Reinforcing ribs 22 are provided at intervals around the inclined portion 15 and the protruding portion 17 around the 10. This allows
The strength of the periphery of the opening 10 against restoration and deformation can be further increased.

FIGS. 7 and 8 show a third embodiment, in which an inclined portion is shown.
By forming the waves 15 in a wavy shape, the strength of the periphery of the opening 10 against restoration and deformation is further increased as in the second embodiment.

[0053]

As described above, in the gas stove cover of the present invention, since the sheet has flexibility formed by backing aluminum foil with paper, it can be easily placed on the top plate of the gas stove. It can be installed along with and does not deform due to heat. The periphery of the opening as the burner exposure hole is raised obliquely upward to form an inclined portion, and a foldable rising portion is formed at the periphery of the sheet via a fold curve, so that the boiled juice out of the sheet Outflow can be reliably prevented.

Further, although the sheet is easily broken, the periphery of the opening is raised obliquely upward to form an inclined portion so as to be along the opening edge on the top plate side. An inclined portion can be formed by bending around the portion, and the sheet can be formed into a shape that can prevent the outflow of boiling juice or the like without breaking the sheet.

The paper is effective in preventing combustion by using flame-retardant paper or non-combustible paper. However, by laminating aluminum foil on the other side of the paper, the paper can be prevented from burning.
Non-combustible paper such as kraft paper can be used, and the sheet is more effective in restoring and suppressing deformation, resulting in excellent shape retention.

Further, when boiling water or the like flows out from the opening to the back surface of the sheet, the water-repellent layer can prevent moisture from penetrating into the paper, thereby preventing restoration and deformation of the sheet.

By forming the inclined portion in a wave shape, the shape retention of the sheet can be further ensured. In addition to this, the inclined portion and the substantially horizontal protruding portion are formed around the opening of the sheet by the bent portion.
