Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to an oil scattering prevention panel used in kitchens and the like to prevent cooking oil and the like from scattering.

[Problems to be solved by conventional technology and ideas] Metal foil such as aluminum foil is installed on top of or around the gas range to prevent cooking oil from scattering. The panel is
It has been widely used for a long time.

In such an oil scattering prevention panel, a bending portion is formed in the longitudinal direction, and by bending at this bending portion, it can be folded into three or four. Moreover, when standing up on a gas range, it is bent at this bending part and the whole is set up in a U-shape. In addition, when installing the panel upright around the gas range, the panel is bent at the bent portions so as to follow the back and side surfaces of the gas range. There is also a type that attaches a magnet to the lower part of the foldable panel surface, and uses this magnet to attach an oil scattering prevention panel to the side or back of the gas range.

By the way, in this kind of oil scattering prevention panel,
In most cases, a hem is formed around the periphery. This edge wrapping cannot be achieved with just the strength of metal foil.
It is formed because it is easy to bend and has insufficient shape retention, and it plays the role of reinforcing the strength of the metal foil. Furthermore, if the cut surface of the metal foil is exposed at the peripheral edge, there is a risk of being cut when a finger or the like comes into contact with it. The edge wrap formed on the peripheral edge also plays a role in preventing such dangers such as injury to the fingers by wrapping such a cut surface inside the edge wrap.

However, as mentioned above, the edge wrapping reinforces the metal foil and improves its bending strength, so when trying to bend the metal foil at a predetermined bending point, the presence of the edge wrapping makes the bending difficult. The problem arises that it becomes difficult. Moreover, even if it is forcibly bent, since it is cylindrical, it will form a corner, which may cause injury to fingers or the like.

FIG. 15 is a perspective view showing an example of a hemline portion of a folded portion of a conventional oil scattering prevention panel. In the conventional oil scattering prevention panel shown in FIG. 15, the hemline portion of the folded portion 1 provided between the panel surface 2 and the panel surface 3 is completely removed. By removing the edge wrapping portion of the folded portion 1 in this manner, the reinforcing effect in this portion is eliminated, and the folding between the panel surfaces 2 and 3 becomes easier. However, since the end 4a of the hem 4 on the panel surface 2, the end 5a of the hem 5 on the panel surface 3, and the end cut surface of the folded portion 1 are exposed near the folded portion 1,
During handling, there is a risk that fingers or the like may come into contact with the ends 4a and 5a and the cut surface of the bent portion 1, causing injury to the fingers or the like.

FIG. 16 is a perspective view showing another example of the folded edge portion of a conventional oil scattering prevention panel, which is disclosed in, for example, Japanese Utility Model Application Publication No. 53-108447. In the oil scattering prevention panel shown in Fig. 16,
Rather than removing the entire hem-wrapping portion of the folded portion, a portion of the inside of the hem-wrapping portion is cut out. A notch 11 is formed in the edge wrap 10 of the folded portion 7 formed on the panel surface 8.
The folded portion 6 between the panel surface 8 and the panel surface 9 is already in a folded state, and although not shown, a notch is also formed in the upper hem of the folded portion 6. By forming such a notch, it is possible to prevent the end of the hem wrap from being exposed at the folded part as shown in FIG. 15, but as shown in FIG.
Corner 12 is formed by bending 0. Since the tip of this corner 12 is sharp, there is a risk of injuring fingers or the like if they come into contact with it. Fig. 16 shows a state in which the panel surfaces 8 and 9 are bent at approximately right angles, but in order to fold the oil scattering prevention panel, it is necessary to further fold the panel surfaces 8 and 9 so that the panel surfaces 9 are closer to each other. . When it is further bent from the state shown in Fig. 16, a large force such as tearing is further applied to the corner 12, and the corner 12 is torn and cut, exposing the cut surface or forming an irregularly shaped protrusion. Sometimes it happens. If such cut surfaces or protrusions are present at the bent part, it may cause injury to fingers etc. when handling, tear the packaging bag containing the oil scattering prevention panel, or protrude outward and damage surrounding objects. This can cause damage to stockings, etc.

Furthermore, such a notch in the edge wrapping portion is formed by forming a notch in advance in the peripheral edge of the metal foil before edge wrapping, and then rolling it in a predetermined direction toward the panel surface side. Therefore, the cutout can only be formed on one side of the panel surface. For example, a four-sided oil splatter panel is typically folded into a W-shape. 12 shows the oil scattering prevention panel shown in FIG. 11. The oil scattering prevention panel 50 shown in FIG. 11 has panel surfaces 51, 52, 53, and 54, and is bent at bending portions 55, 56, and 57. However, the bent portion 55
and the bending direction of 57 and the bending portion 56
This is the opposite direction to the bending direction. For this reason,
At any one of these folds, the panel must be folded with the panel surface side on which the notch is formed facing outward. If you try to fold it with the notch on the outside in this way, the strength of the folded portion will be weakened and sharp protrusions etc. will be more likely to be formed. Additionally, the cut surface is exposed to the outside, creating a more dangerous situation.

In addition, in conventional oil-scattering prevention panels, instead of forming notches in the hem wrapping, a so-called semi-curl, which reduces the amount of hem wrapping, is formed as the hem wrapping, thereby reducing the reinforcing effect of the hem wrapping. In some cases, methods are used to make it easier to bend, but in the same way as notch formation, in the case of such semi-curls, the hem of the folded part may break, exposing the cut surface, or creating an irregular shape. There was a problem that protrusions etc. were formed and it was not possible to sufficiently prevent danger.

Therefore, it is an object of this invention to provide an oil-scattering prevention panel in which the cut surface is not exposed at the hem of the folded portion, and no sharp corners or protrusions are formed at the tip.

[Means for Solving the Problems] The oil scattering prevention panel of this invention is an oil scattering prevention panel made of metal foil that has an edge wrap around the periphery and can be folded at the bending portion. It is characterized by being flat.

[Function] In the oil scattering prevention panel of this invention, the edge wrapping at the folded portion is made flat, so there is no reinforcement by the edge wrapping at this portion, making it easier to fold. In addition, since it is easier to bend than the conventional notch formation or semi-curl, there is no need to apply excessive force to the hemline, which prevents the exposed cut surface due to breakage or irregular shapes. There is no formation of protrusions etc.

[Embodiment] FIG. 1 is a front view showing an embodiment of this invention. In the oil scattering prevention panel 20 shown in FIG. 1, a bent portion 25 is formed between the panel surface 21 and the panel surface 22. Also, panel surface 2
A bent portion 26 is formed between 2 and the panel surface 23. A hem wrap 24 is formed on the periphery of the oil scattering prevention panel 20. Panel surface 2
1, 22, and 23 are provided with patterns as shown in the figure by forming irregularities on the metal foil. Of course, such a pattern is completely arbitrary in this design.

FIG. 2 is an enlarged front view showing the hemline portion of the folded portion of the embodiment shown in FIG. 1. Also, the third
The figure is a plan view showing the hemline portion of the folded portion shown in FIG. 2. As shown in FIGS. 2 and 3, the hemline portion of the folded portion 25 is crushed to form a flat folded portion 29. As shown in FIGS. Moreover, a flat tapered part 27 and a flat tapered part 28 are formed on both sides of the flat bent part 29, and the hem 24 gradually becomes flattened as it approaches the upper part of the bent part 25.

The bent portion 25 also includes a linear protrusion 25a that bulges toward the front side of the drawing in FIG.
The grooves 25b and 25c are formed on both sides of the groove 25b and 25c and are recessed toward the back side of the drawing in FIG. −
A cross-sectional view showing the bent portion 25 along the line is shown in FIG.

Here, a method for forming the flat bent portion 29 and the flat tapered portions 27 and 28 shown in FIGS. 2 and 3 will be described. FIG. 4 is an enlarged front view showing the state before the hem-wrapped portion of the folded portion is flattened. As shown in FIG. 4, the hemline portion of the folded portion before flattening is formed to have a smaller diameter than the hemline 24. The hem-wrapping tapered portion 30 and the hem-wrapping tapered portion 30 and the hem-wrapping tapered portion 30 are arranged so that the portion of the hem-wrapping bent portion 32 corresponding to the flat bent portion 29 has the smallest diameter, and the diameter of the hem-wrapping gradually becomes smaller as it approaches the hem-wrapping bent portion 32. 31 is formed. Such adjustment of the edge wrapping diameter is possible, for example, by suitably adjusting the diameter of a curl groove for forming the edge wrapping in a mold for press-molding the oil scattering prevention panel.

The edge-wrapping bent portion 32 corresponding to the flattened bent portion 29 is crushed most strongly to flatten it, and the edge-wrapping tapered portion 3 corresponding to the flattened tapered portions 27 and 28 is formed.
0 and 31 are flattened so as to become thinner as they approach the hem-wrapping bent portion 32.
As a result, the peripheral edge of the flattened hem wrap is
As shown by the dashed line in the figure, it is formed substantially in a straight line so as to be aligned with the peripheral edge of the hem wrap 24. If the diameter of the hem wrap around the folded part is made to be the same as the diameter of the hem wrap around the other parts, when it is flattened, this flat part will protrude beyond the periphery of the other hem wraps, causing this problem. If the flat portion is located at the lower part of the oil scattering prevention panel, when it is placed upright on a gas range, the protruding flat portion may make the standing state unstable. In this example,
As mentioned above, by making the diameter of the edge wrap of the folded portion smaller than the diameter of the edge wrap of the other portions, it is possible to prevent the periphery of the flattened portion from protruding beyond the periphery of the edge wrap after flattening. ing. Furthermore, in this embodiment, the hem-wrapping tapered portions 30 and 31 are formed and are flattened so that the thickness thereof gradually becomes thinner as it approaches the bent portion.
The peripheral edge of the oil scattering prevention panel after being flattened is arranged in a straight line. This stabilizes the standing state when it is placed upright on the gas range, and it can be made more desirable from the standpoint of appearance.

FIG. 5 is a plan view showing the curved state of the hemline portion when it is bent at the bending portion. In the folded part, the edge wrapping part is flattened to form a flat folded part 29, and this flat folded part 29
Since it no longer has a reinforcing effect, it is a part that can be easily deformed. Therefore, as shown in FIG. 5, it curves smoothly when folded. Therefore, unlike in the conventional case, the cut surface is not exposed due to breakage, or irregularly shaped protrusions are not formed.

In this embodiment, the bending portion 25 is devised so that the flat bending portion 29 curves smoothly when folded. FIG. 6 is a partial sectional view taken along - in FIG.
5 is shown. As shown in FIG. 6, the bent portion 25 has a linear convex portion 25a bulging toward the bent side.
and grooves 25b and 25 formed on both sides thereof.
It is composed of c.

FIG. 7 is a partial sectional view showing such a bent portion 25 in a bent state. As shown in FIG. 7, in the groove portion 25b and groove portion 25c,
It is bent so that the panel surface 21 and the panel surface 22 face each other. Therefore, the panel surface 21 and the panel surface 22
It is bent so that the distance between the two is relatively large.

FIG. 8 is a partial cross-sectional view showing a conventionally adopted bending portion that is bent using only one strip, and corresponds to FIG. 6. A bent portion 75 is provided between the panel surfaces 31 and 32, and this bent portion 35 is formed as a groove protruding toward the side opposite to the bent side. FIG. 9 is a partial sectional view showing a state in which the bent portion shown in FIG. 8 is bent. As shown in FIG. 9, when it is bent at such a bending portion 35, the distance between the panel surface 31 and the panel surface 32 becomes relatively small.

In this embodiment, as shown in FIG. 7, by employing a folding section having grooves on both sides of the linear convex section, the distance between the panel surfaces when folded is made relatively large. When the flat bent part 29 is bent, it curves smoothly without forming any corners.

FIG. 10 is a plan view showing a state in which the three-sided oil scattering prevention panel is folded into three. 1st
In Figure 0, the oil scattering prevention panel is on panel surface 4.
1, 42 and 43, and are folded by being bent at bending portions 46 and 45, respectively. As shown in FIG. 10, in this folded state, the panel surface 43 is located between the panel surfaces 41 and 42, so the bent portion 46 is bent so that the distance between the panel surfaces is wider than the bent portion 45. It will be done. In consideration of the folded state of each of the folded parts, the widths of the linear protrusions, grooves, etc. of the folded parts can be adjusted as appropriate.

11 is a plan view showing a state in which the four oil-splash prevention panels are folded. The oil-splash prevention panel 50 shown in FIG. 11 has panel surfaces 51, 52,
The panel has flattened sections 53 and 54, which are bent at bent portions 55, 56 and 57, respectively. As explained in the description of the prior art, bent portions 55 and 57 are bent in the opposite direction to bent portion 56. Conventional notches and semi-curls are provided only on one side of the panel surface, and are hardly effective for bending to the other side. However, the flattened sections formed by this invention are effective on both sides of the panel surface, and the effects of this invention can be achieved regardless of the bent portion that is bent to either side.

FIG. 12 is a plan view showing a state in which the bending assisting member 60 is applied to the hem-wrapped portion of the folded portion and the folded portion is bent. As a device for smoothly curving the flat bent portion 29 when it is bent at the bent portion, we have already explained the structure of the linear convex portion at the bent portion and the groove portions on both sides of the linear convex portion, but here,
The use of the bending auxiliary member during bending will be explained. As shown in FIG. 12, when folding, a bending auxiliary member 60 having a smoothly curved outer peripheral surface is applied to the inside of the flat bent part 29, and the flat bent part 29 is bent along the circumferential surface of this bending auxiliary member 60. By curving the plane bending portion 29, it is possible to curve the plane bending portion 29 into a desired shape. However, the use of such a folding aid is not a limitation of this invention.

FIG. 13A is a plan view showing an example of a hem-wrapped portion of a bent portion that is curved in advance before being bent. As shown in FIG. 12, it is possible to restrict the flat bent portion 29 to a desired shape during bending, but it is also possible to curve the flat bent portion 29 in advance before bending. be. As shown in FIG. 13A, if the flat bent portion 29 is curved in advance, the flat bent portion 29 can be formed into a smoothly curved shape without forming a corner portion during bending.

FIG. 13B is a plan view showing another example of a hemline portion of a folded portion that is curved in advance before being folded. Moreover, FIG. 13C is an enlarged front view of the embodiment shown in FIG. 13B. Figures 13B and 13
Referring to Fig. C, in this embodiment, a linear convex portion 25a and grooves 25b and 25c formed in the bent portion 25 between the panel surface 21 and the panel surface 22 are extended in the flat bent portion 29. It is formed. Therefore, the flat bent portion 29
Similarly to the bent portion 25, the grooves are also formed with irregularities as shown in FIG. In this way, the edge wrapping 24
By forming the same unevenness as the panel surface on the flat bent portion 29, the flat bent portion 29 can be formed into a smooth curved shape without forming a corner portion when the panel surface is bent. In addition, if the flat bent portion 29 has such a shape, the linear shape of the bent portion 25 between the panel surfaces is similar to the convex portion 2.
It can be formed simultaneously with the formation of grooves 5a and grooves 25b and 25c. however,
They do not have to be formed at the same time.

FIG. 14 is an enlarged front view showing another embodiment of this invention. This embodiment can be obtained, for example, by crushing and flattening the hem portion of the folded portion of a conventional oil scattering prevention panel. In FIG. 14, the flat portion 79 is formed by simply crushing the hem of the bent portion 75. In this example,
The diameter of the edge wrapping at the bent part is the same as the edge wrapping 7 of the other part.
4, the edge of the peripheral edge of the flattened portion 79 is
It protrudes outward from the edge of the circumferential edge of the hem wrap 74. Further, the bent portion 75 of this embodiment is constituted by a conventionally employed single-stripe groove portion as shown in FIG. In this way, the effect of this invention can be fully exhibited by simply flattening the edge wrapping of the folded portion of the conventional oil scattering prevention panel. Make the diameter of the hem wrapping at the bent part smaller than the diameter of the hem wrapping at other parts,
Furthermore, forming a tapered part that gradually reduces the diameter, constructing the folded part from a linear convex part and grooves on both sides, using a folding auxiliary member during folding, and pre-rolling the edges of the folded part. Providing a curved shape to a portion is not an essential requirement of this invention, but merely represents a more preferable embodiment.

In the above embodiment, an example of an oil scattering prevention panel installed above a gas range was explained.
The oil scattering prevention panel of this invention is not limited to this type, but also includes a type in which a magnet is provided below the panel surface and can be attached to the side and back of a gas range using the magnet. . Further, the number of panel surfaces is not particularly limited, and it is sufficient to have a plurality of panel surfaces with bending portions interposed therebetween.

[Effects of the invention] As explained above, in the oil scattering prevention panel of this invention, by making the edge wrapping of the bending part flattened, the bending at the bending part is made easier, and the cut surface is exposed due to breakage during bending. or,
It is possible to prevent the formation of irregularly shaped protrusions, etc., and to further sufficiently prevent dangers during handling, which is one of the original purposes of hem wrapping.
