Description

The present invention relates to a sheet for preventing the back surface of a rectifier plate of a range hood to which the rectifier plate is attached from becoming dirty.

Range hoods installed above the range for ventilation in system kitchens, etc., tend to attract oil stains from cooking, so prevent stains by installing a filter to cover the sirocco fan inside the range hood. Various attempts have been made.

By the way, in recent years, range hoods that come with a rectifier plate have become popular.
Referring to FIGS. 5 and 6, in this type of range hood 1, a flat rectifying plate 3 is installed with a predetermined gap immediately below the opening of the hood body 2, that is, the intake port 2a, and the air intake is is being carried out.
By narrowing the gap in this way, the air passing through it is accelerated and the suction power is increased.

A grease filter 2f attached to the intake port 2a is known as a general filter attached to the range hood 1 to which such a rectifying plate 3 is attached.
In addition, a sheet-like filter made of a flame-retardant material such as glass fiber has been developed, as in Patent Document 1, which is inserted between the rectifier plate and the intake port of the range hood body without any gap.

According to the filter of Patent Document 1, the air containing oil smoke, etc., taken in through the gap between the rectifier plate and the range hood body is filtered through the filter and then sent outside by the sirocco fan. etc., from getting dirty.

Japanese Patent Application Publication No. 2018-153751

However, as mentioned above, the air containing oil smoke passes through the gap between the rectifier plate and the range hood body, so the back surface of the rectifier plate (the surface facing the range hood body) becomes a path for oil smoke, so to speak. It has a structure that allows oil smoke to easily adhere to it.
In addition, oil droplets adhering to the opening edge of the air intake port of the range hood body may drip down toward the back side of the rectifier plate. In addition, some oven hoods have an oil tray on the opening edge of the air inlet (not shown) to catch oil droplets falling from the sirocco fan, but if the range hood is used for a long period of time, oil may accumulate in the oil tray and overflow from there. In some cases, oil droplets may also drip down toward the back surface of the current plate.

For this reason, oil stains accumulate not only on the sirocco fan, etc., but also on the back surface of the current plate, but no attempt has been made to suppress this in the past. Generally, rectifier plates are large in size, so cleaning them when they become dirty takes time and effort.

This point is the same even when the filter of Patent Document 1 is used, and since it is in close contact with the part directly under the intake port on the back side of the current plate, even if the dirt can be suppressed to some extent, the current plate Most of the back side remained exposed and staining could not be suppressed. Furthermore, when the filter of Patent Document 1 is used, the entire predetermined gap between the air intake port and the rectifying plate is filled with the filter, which may reduce the air intake performance of the range hood. .

Therefore, the problem to be solved by the present invention is to provide a new attempt to prevent the back surface of the current plate of a range hood to which the current plate is attached from becoming dirty.

In order to solve the above-mentioned problems, the present invention is a dirt prevention sheet that can be installed to cover the surface (back surface) facing the range hood main body of the rectifier plate of a range hood with a rectifier plate, which prevents air from being taken in through the gap. This structure prevents air containing oil smoke from coming into contact with the opposing surface (back surface) of the rectifier plate, and also catches oil stains dripping from the side of the range hood body.

By configuring the stain prevention sheet for the rectifier plate of a range hood in this way, the back surface of the rectifier plate can be easily prevented from becoming dirty, and the time and effort for cleaning the rectifier plate can be reduced.
When the antifouling sheet becomes dirty to a certain extent, it is removed from the back of the baffle plate and discarded, and a new antifouling sheet is installed on the back of the baffle to keep the baffle clean.

The stain prevention sheet for the current plate of a range hood according to the invention includes a nonwoven fabric layer that is located on the side of the range hood body in the installed state and captures oil smoke and oil droplets, and a nonwoven fabric layer that is located on the back side of the current plate in the installed state, It is preferable to adopt a configuration including a film layer that prevents oil smoke and oil droplets captured by the nonwoven fabric layer from penetrating into the back surface of the current plate.

With this configuration, oil smoke and oil droplets are reliably captured by penetrating into the nonwoven fabric layer, and the oil smoke and oil droplets are blocked by the film layer and do not contaminate the back side of the current plate. It is possible to further prevent stains.

In the dirt prevention sheet for the rectifier plate of a range hood according to the invention, an adhesive layer is further provided between the nonwoven fabric layer and the film layer, and by peeling off a part of the film layer and exposing the adhesive layer, it can be applied to the back side of the rectifier plate. It is more preferable to employ a configuration that allows attachment.

With this configuration, the anti-fouling sheet can be easily fixed to the back of the rectifying plate, which prevents the anti-fouling sheet from shifting due to wind pressure or coming off the back of the rectifying plate during use. It can be prevented.
In addition, even if a part of the film layer is peeled off during use, the film layer remains on the back side of the rectifier plate where many oil droplets fall, so that the film layer in those areas blocks oil droplets. Performance can be maintained.

In the stain prevention sheet for the current plate of a range hood according to the invention, a slit is formed in the film layer, and a configuration is adopted in which a portion from the slit of the film layer to the outer edge of the sheet can be peeled off. is more preferable.

With this configuration, it is possible to easily peel off a part of the film layer and expose the adhesive layer without using a cutting tool such as a cutter, thereby improving convenience.

In the stain prevention sheet for rectifying plate of a range hood according to the invention, it is more preferable to adopt a configuration in which the film layer has a printed display indicating the position of the slit.

With this configuration, the position of the slit, which is the starting point for peeling off the film layer, becomes clear, making it easier to peel off part of the film layer to expose the adhesive layer, further improving convenience. do.

In the dirt prevention sheet for rectifying plates of range hoods according to the invention, the adhesive layer has missing layers arranged in parallel at regular intervals in the vertical or horizontal direction of the sheet, and the sheet can be cut along the missing layers. It is preferable to adopt a configuration in which:

There are various aspect ratios and dimensions of rectifier plates for commercially available range hoods, and with this configuration, the sheet can be cut as appropriate to match the aspect ratio and dimensions of the rectifier plate to be installed. This improves convenience.
Cutting along the missing layer prevents the adhesive of the adhesive layer from adhering to the blade of a cutting tool such as scissors or a cutter, thereby preventing the blade from becoming dirty or reducing cutting performance.

Since the stain prevention sheet according to the invention is configured as described above, it is possible to prevent the back surface of the current plate of a range hood to which the current plate is attached from becoming dirty.

Embodiments of the present invention will be described below with reference to the drawings.
The stain prevention sheet 10 of the embodiment shown in FIGS. 1 and 2 is attached to the back side of the rectifier plate 3 of the range hood 1, as shown in FIGS. This is to prevent

As shown in FIGS. 1 and 2, the stain prevention sheet 10 of the embodiment is rectangular in plan view, and includes a nonwoven fabric layer 11, a film layer 12, and a layer interposed between the nonwoven fabric layer 11 and the film layer 12 in the thickness direction. It has a three-layer structure consisting of an adhesive layer 13. Note that since the film layer 12 is transparent, the adhesive layer 13 is visible through it in FIG.
When in use, it is installed on the back surface of the current plate 3 so that the nonwoven fabric layer 11 faces the side of the hood body 2 and the film layer 12 faces the back side of the current plate 3, and is fixed by the adhesive layer 13. .

The vertical and horizontal dimensions of the rectangular antifouling sheet 10 are not particularly limited, but examples that match the dimensions of a general current plate 3 include a vertical dimension of 25 cm to 51 cm and a horizontal dimension of 30 cm to 85 cm.
If the dimensions are too large, it will be inconvenient to handle, and if it is installed on the back side of the current plate 3, it will take time and effort, such as having to cut it into a large size.If the size is too small, it will be exposed on the back side of the current plate 3. This will result in spots being formed, and it will not be possible to sufficiently prevent the stains.

The nonwoven fabric layer 11 shown in FIG. 2 is made of nonwoven fabric. Oily smoke adheres to this nonwoven fabric, and oil droplets dripping from the side of the hood body 2 of the range hood 1 permeate, thereby trapping dirt.
The material of the nonwoven fabric is not particularly limited, and examples include synthetic fibers and natural fibers such as polyester fibers, polyamide fibers, and polyimide fibers. Non-woven fabrics are preferred. Further, in order to impart flame retardancy to the nonwoven fabric, it is preferable to apply flame retardant processing such as blending a flame retardant into the fibers or attaching a flame retardant to the surface of the nonwoven fabric.
The method for producing the nonwoven fabric is not particularly limited either, and examples thereof include a thermal bond method, a chemical bond method, a spun bond method, and the like.

The thickness of the nonwoven fabric layer 11 is also not particularly limited, but is preferably in the range of 0.5 to 5 mm, and more preferably in the range of 1 to 2 mm. Furthermore, the basis weight is not particularly limited, but it is preferably in the range of 20 to 60 g/m ² , and more preferably in the range of 30 to 50 g/m ² .
Within these ranges, the nonwoven fabric layer 11 will not be too thin and dirt retention performance will be impaired, or the nonwoven fabric layer 11 will not be too thick and bulky and the air intake performance of the range hood 1 will not be impaired.

The film layer 12 shown in FIGS. 1 and 2 is made of a synthetic resin film. The presence of the film layer 12 with high watertightness and liquid tightness blocks oil smoke and oil droplets that have soaked into the nonwoven fabric layer 11 from reaching the back surface of the current plate 3, and prevents the current plate 3 from becoming dirty. Ru.
The material of the film is not particularly limited, and examples include polyethylene terephthalate, polypropylene, and polyethylene, but PET film, which has high heat resistance, is preferred as it is suitable for the environment that tends to reach high temperatures, such as inside a range hood. Further, the film layer 12 may be provided with flame retardancy.

The thickness of the film layer 12 is also not particularly limited, but is preferably in the range of 0.2 to 2 mm, and more preferably in the range of 0.3 to 1 mm.
Within these ranges, the film layer 12 will not be too thin and tear and the dirt blocking performance will be impaired, or the film layer 12 will be too thick and bulky and the air intake performance of the range hood 1 will not be impaired. do not have.

As shown in FIG. 1, an upper slit 12a and a lower slit 12b are formed in the upper and lower parts of the film layer 12, respectively, to cross the stain prevention sheet in the left-right direction.
These upper slits 12a and lower slits 12b divide the stain prevention sheet 10 into three parts: an upper part 10a, a lower part 10b, and an intermediate part 10c that occupies most of the part.

In addition, starting from these upper slits 12a and lower slits 12b, the upper part 10a extends from the upper slit 12a to the upper edge of the stain prevention sheet 10, and the lower part 10b extends from the lower slit 12b to the lower edge of the stain prevention sheet 10. , it is possible to peel it off from the stain prevention sheet 10.
As shown in the figure, the width of the upper part 10a, that is, the distance between the upper slit 12a and the upper edge of the stain prevention sheet 10, is narrower than the width of the lower part 10b, that is, the distance between the lower slit 12b and the lower edge of the stain prevention sheet 10. The width is about 1/3 to 1/2 of the width of the lower part 10b.

Printed markings 12c are formed on the surface of the film layer 12 to indicate the positions of the upper and lower slits 12a, 12b.
The slits 12a and 12b themselves have almost no width and are difficult to see, but the existence of the printed display 12c makes it easy to confirm the position of the slits 12a and 12b, and the stain prevention sheet 10 is used. When doing so, the film layer 12 on the upper part 10a and the lower part 10b can be easily peeled off.
In the figure, the print display 12c is in the shape of an arrow, but it is not limited to this. For example, a line parallel to the slit is placed on both sides of the slit at a predetermined distance (approximately 1.0 mm to 10 mm) from the slit. It is also possible to print individual strips on the film layer 12. In this way, two parallel lines centered on the slit are displayed as the print display 12c, making it easier to see that the slit exists at the center of the two parallel lines.

The adhesive layer 13 shown in FIGS. 1 and 2 includes an adhesive part 13a made of an adhesive arranged between the nonwoven fabric layer 11 and the film layer 12 in a predetermined pattern in a plan view.
Further, as shown in the figure, cutout portions 13b are formed in the left-right direction of the adhesive layer 13, which are arranged in parallel at regular intervals and extend in the vertical direction where no adhesive is present.
Further, in the lower part 10b, cutout portions 13b are formed in the vertical direction of the adhesive layer 13 as well, and are arranged in parallel at regular intervals and extend in the left-right direction where no adhesive is present.

The dimensions of the dirt prevention sheet 10 are adjusted to match the dimensions of the rectifying plate 3 by cutting the entire dirt prevention sheet 10 in the horizontal direction and the lower part 10b in the vertical direction along these missing parts 13b. It's easy to do.
When cutting along the missing portion 13b, the adhesive is not attached to the blade of a cutting tool such as a cutter.
Since the film layer 12 is transparent, it is easy to check the missing portion 13b of the adhesive layer 13 through the film layer 12.

In the upper part 10a and the lower part 10b of the stain prevention sheet 10, the occupation ratio of the adhesive of the adhesive layer 13 is larger than that in the middle part 10c.
That is, in the upper part 10a and the lower part 10b, the adhesive part 13a has a rectangular shape with the inside filled with adhesive, but in the middle part 10c, the adhesive part 13a has adhesive only on the outer edge. It has the shape of a square ring.
The upper portion 10a and the lower portion 10b have a large proportion of adhesive, thereby increasing the adhesion force to the back surface of the rectifying plate 3, which will be described later.
In addition, since the intermediate portion 10c, which forms the majority, is not attached to the back surface of the rectifier plate 3, the proportion of adhesive used can be reduced to the extent that the laminated state of the film layer 12 and the nonwoven fabric layer 11 can be maintained, thereby reducing costs. is suppressed. At the same time, since the film layer 12 easily shrinks due to heat, by laminating the film layer 12 on the nonwoven fabric layer 11 via the adhesive layer 13, the adhesive layer 13 can suppress the shrinkage of the film layer 12. This prevents the dirt prevention sheet 10 from waving or warping even when used in a range hood that gets hot.
Most of the adhesive layer 13 corresponding to the upper and lower slits 12a and 12b are adhesive parts 13a, increasing the adhesive strength, and when pasted on the back surface of the rectifying plate 3, which will be described later, the upper part 10a and The boundary with the intermediate portion 10c and the boundary between the lower portion 10b and the intermediate portion 10c are prevented from rising.

The type of adhesive constituting the adhesive layer 13 is not particularly limited, but examples include urethane adhesive, acrylic adhesive, and silicone adhesive. Urethane-based adhesives are preferred as they are difficult to remove. Note that it is preferable to impart flame retardancy to the adhesive by, for example, adding a flame retardant component to the adhesive.
The area ratio of the adhesive layer 13 to the entire surface of the stain prevention sheet 10 is also not particularly limited, but may be 10% to 60%.
If it is within these ranges, the area ratio may be too small, resulting in insufficient adhesive strength, or the area ratio may be too large, resulting in high costs, or the entire stain prevention sheet may be greatly undulated due to heat shrinkage of the film layer 12. This will prevent you from doing so.
The thickness of the adhesive layer 13 is also not particularly limited, but may be 5 μm to 80 μm, for example.
If the thickness is within these ranges, it will be possible to prevent the adhesive from being too thin, resulting in insufficient adhesive strength, or from being too thick, resulting in an adhesive layer remaining as adhesive residue when peeled off, resulting in high costs. be done.
The method of forming the adhesive layer 13 is also not particularly limited, and examples include pattern printing and spray coating.

The structure of the stain prevention sheet 10 of the embodiment is as described above, and how to use it will now be described with reference to FIGS. 3 to 5 (and FIG. 6 if necessary).

First, as shown in FIG. 3, a dirt prevention sheet 10 is prepared which has been cut along the missing portion 13b in accordance with the dimensions of the current plate 3 to be attached.
Regarding this stain prevention sheet 10, the film layer 12 of the upper part 10a and the lower part 10b is peeled off starting from the upper and lower slits 12a and 12b. Thereby, the adhesive layer 13 is exposed at the upper part 10a and the lower part 10b.

Next, as shown in FIG. 4, the rectifier plate 3 of the range hood 1 is opened, and the antifouling sheet 10 is placed so that the film layer 12 side faces the back surface of the rectifier plate 3, and the upper part 10a of the sheet is placed on the rectifier plate. The lower part 10b of the rectifying plate 3 is positioned on the front side (lower side in the open state) of the rectifying plate 3, and is pressed against the back surface of the rectifying plate 3.
The antifouling sheet 10 is attached to the back surface of the rectifying plate 3 and fixed by the adhesive layer 13 on the upper part 10a and the lower part 10b. At this time, it is preferable to attach the upper part 10a located on the upper side first and the lower part 10b located on the lower side later because the stain prevention sheet 10 will not turn over and fall under its own weight.
The rectifying plate 3 can be vertically swung around a hinge 3a on the rear side, thereby allowing it to be opened and closed.

Furthermore, as shown in FIGS. 5 and 6, by swinging the rectifying plate 3 upward and fixing it to the hood body 2 with the fixing fitting 3b on the front side while covering the intake port 2a of the hood body 2, , the installation of the dirt prevention sheet 10 is completed.
In this state, when the operating button 2b provided on the outer surface of the hood body 2 is pressed to operate the sirocco fan 2d housed in the fan casing 2c inside the hood body 2, the back surface of the rectifier plate 3 and the hood body 2 Air intake starts through the gap, and oily smoke generated from a range or the like is sucked into the range hood 1.
The oil smoke passes through the sirocco fan 2d and is finally exhausted from the ventilation duct 2e.
In the figure, the intake port 2a is covered with a grease filter 2f that captures fat components of oil smoke.

As shown in the figure, the gap between the back surface of the baffle plate 3 and the hood body 2 serves as a passage for oil smoke, and since the back surface of the baffle plate 3 is covered with a dirt prevention sheet 10, the covered portion Oil smoke does not come into direct contact with the current plate 3. The nonwoven fabric layer 11 of the stain prevention sheet 10 facing toward the path of oil smoke captures dirt D such as oil smoke.
In addition, oil smoke adheres to the opening edge of the intake port 2a and the grease filter 2f, and this accumulates to form oil droplets that drip down toward the back surface of the current plate 3, or to the opening edge of the intake port (not shown). Oil droplets overflowing from the oil tray may drip down toward the back surface of the rectifier plate, and the nonwoven fabric layer 11 also captures dirt D such as such oil droplets.

Here, some of the dirt D such as oil droplets is likely to seep through from the nonwoven fabric layer 11 to the back surface of the current plate 3, but in the middle part 10c that occupies most of the dirt prevention sheet 10, there is Since the film layer 12 with excellent watertightness and liquidtightness exists, dirt D such as oil droplets is blocked here and does not reach the back surface of the current plate 3. In particular, when the stain prevention sheet 10 is configured so that the center of the intermediate portion 10c is located at a position corresponding to the intake port 2a, the film layer 12 prevents dirt D such as oil droplets dripping from the vicinity of the intake port 2a. It is possible to reliably shut off and prevent the back surface of the current plate 3 from becoming dirty.
Therefore, the stain prevention sheet 10 sufficiently prevents the back surface of the rectifying plate 3 from becoming contaminated with stains D such as oil smoke and oil droplets.

Note that when the antifouling sheet 10 is used, the film layer 12 is not present in the upper part 10a and the lower part 10b, and therefore, the film layer 12 is not as effective in blocking oil droplets that have permeated through the nonwoven fabric layer 11 at these locations. cannot be obtained.
However, oil droplets usually drip down around the area directly below the intake port 2a, and when the stain prevention sheet 10 is installed, the upper part 10a and the lower part 10b are located far closer to this side than directly below the intake port 2a. Since it is located at the back, oil droplets will not drip here.
In particular, in the range hood 1, the intake port is not located in the center but is often placed biased to the back side, but when the dirt prevention sheet 10 is installed, the width of the upper part 10a located at the back side is small. Since the width of the lower portion 10b located on the near side is formed to be large, a sufficient measure is taken to prevent the portion where the film layer 12 is not present from reaching directly under the air intake port 2a. In addition, there is an adhesive layer 13 in most parts of the upper part 10a and the lower part 10b, and this adhesive layer 13 also plays the same role as the film layer 12, so it is more effective than when the stain prevention sheet 10 is not used. It has the effect of preventing stains.
In this way, when using the range hood, the dirt prevention sheet 10 is pasted on the back side of the rectifier plate, so that the oil dripping from the sirocco fan in the intake port 2a is caught by the dirt prevention sheet. Since the dirt prevention sheet 10 located directly under the fan has a film layer 12, the back surface of the current plate will not become dirty. Furthermore, when replacing the dirt prevention sheet 10, the current plate will be opened again and the current plate will be positioned vertically, so there is a risk that oil will drip down along the vertical direction. The prevention sheet 10 includes a nonwoven fabric layer 11, and since the nonwoven fabric layer 11 absorbs oil, it is possible to prevent oil from dripping from the stain prevention sheet when it is replaced.

The widths of the upper part 10a and the lower part 10b are not particularly limited, but as described above, since they do not have the effect of blocking oil droplets during use, they are preferably 0.8 cm to 20 cm, and the width of the upper part 10a is 2 cm. It is more preferable that the width of the lower part 10b is 5 cm to 15 cm. In this embodiment, the width of the upper portion 10a is approximately 5 cm, and the width of the lower portion 10b is approximately 13 cm.
If it exceeds 20 cm, the width of the upper part 10a and the lower part 10b that do not have the film layer 12 is too large during use, and there is a risk that the back surface of the rectifying plate 3 will be contaminated by oil droplets that have penetrated through the nonwoven fabric layer 11. be.
Moreover, if it is less than 0.8 cm, the width of the upper part 10a and the lower part 10b is too small, and there is a possibility that a sufficient adhesion effect to the back surface of the current plate 3 cannot be obtained.

The embodiments disclosed herein are illustrative in all respects and are not restrictive.
The scope of the present invention is indicated by the claims, and shall include all modifications and changes within the scope and equivalent meaning thereof.

In the embodiment, the antifouling sheet 10 has a three-layer structure of the nonwoven fabric layer 11, the film layer 12, and the adhesive layer 13, but it is not limited to this as long as it can be installed on the back surface of the current plate 3.
For example, a single layer structure consisting of only the nonwoven fabric layer 11 or only the film layer 12 may be used.
Alternatively, a two-layer structure consisting of the nonwoven fabric layer 11 and the film layer 12, the nonwoven fabric layer 11 and the adhesive layer 13, and the film layer 12 and the adhesive layer 13 may be used. When the adhesive layer 13 is present, the back side of the current plate 3 It is possible to paste it on.

In the case of a single-layer structure consisting of only the non-woven fabric layer 11 or only the film layer 12, or a two-layer structure consisting of the non-woven fabric layer 11 and the film layer 12, it cannot be attached to the back side of the rectifying plate 3 as it is, but it is necessary to attach a magnet separately. It can also be fixed to the back surface of the rectifier plate 3 using double-sided tape, hook-and-loop fastener, etc. so as not to shift.
Furthermore, an antibacterial layer containing an antibacterial agent to prevent bacteria from propagating on the stain prevention sheet 10, and a highly shape-retaining layer to prevent the stain prevention sheet 10 from bending or waving when installed. It may contain layers other than the nonwoven fabric layer 11, the film layer 12, and the adhesive layer 13, such as a shape-retaining layer.

In the embodiment, slits 12a and 12b are provided on the upper and lower sides of the film layer 12, and by peeling off the film starting from these slits 12a and 12b, the adhesive layer 13 is exposed on the upper part 10a and the lower part 10b of the stain prevention sheet 10, and the rectification is performed. Although the adhesive layer 13 is attached to the back surface of the plate 3, the position of the slit and the location where the adhesive layer 13 is exposed by peeling off the film are not limited thereto.

For example, a configuration may be adopted in which slits are provided on the left and right sides of the film layer 12 and the adhesive layer 13 is exposed on the left and right sides of the stain prevention sheet 10 by peeling off the film starting from the slits. The widths of the left and right portions may be the same or different.
Furthermore, the slits and the locations where the adhesive layer 13 is exposed may be provided on the top, bottom, right and left, or conversely, may be provided only on one of the top, bottom, left and right.
Further, even when slits are provided above and below, although the widths of the upper part 10a and the lower part 10b are different in the embodiment, they may be the same.
Further, in place of the slits, easy-to-break lines such as perforations or half-cuts may be used.

The pattern of the adhesive layer 13 is not limited to the embodiment, and for example, the adhesive may be applied all over the entire surface or a desired portion, or may be dotted. Alternatively, the adhesive layer may be formed entirely or partially by spray coating.
When the dots are dotted, gaps 13b are formed between adjacent dots, and the stain prevention sheet 10 can be cut along these lines to adjust the size. Adhesion of adhesive can also be prevented.

Although the film layer 12 is transparent in the embodiment, it can also be opaque.
In this case, since it becomes difficult to visually recognize the missing portion 13b through the film layer 12, a printed indication indicating the position of the missing portion 13b may be provided on the film layer 12, as in the case of the slits 12a and 12b.

In the embodiment, the stain prevention sheet 10 has a rectangular shape, but is not limited to this, and may be circular, oval, polygonal, etc.
