Description

  The present invention relates to a lightweight dish made of raw materials such as plant fibers and synthetic resins, and more particularly to a lightweight dish having a shape that is difficult to fly even under wind.

Conventionally, when eating outdoors such as events and barbecues, there are many people who participate, so a lightweight dish made of paper or metal foil is used to reduce the burden of transportation and cleaning. It is common to do.
As such a light weight dish, for example, Patent Document 1 discloses a paper dish suitable for outdoor use under the name “paper dish”. The paper plate disclosed in Patent Document 1 includes a bottom plate portion on which food is placed, a peripheral wall plate portion that rises from the peripheral edge portion of the bottom plate portion, and extends outward and obliquely downward from the upper end portion of the peripheral wall plate portion. And an outer flange portion that is bent outwardly and obliquely downward from the front end portion of the inner flange portion and has a small width. In the device having such characteristics, the outer flange portion suppresses deformation of the inner flange portion, so that the shape retention of these flange portions can be improved.

However, when the device disclosed in Patent Document 1 is used outdoors, there is a problem that because of its light weight, the dish is often crushed, scattered, and turned over by the wind.
The reason why the dish is blown by the wind is that the outer flange, which is the outer end of the peripheral wall plate part of the dish, is positioned above the bottom plate part, so that the wind is blown below the inner flange part. It is thought that it is possible to penetrate.
Therefore, by extending the outer flange portion to the same height as the bottom plate portion, it may be possible to prevent wind from entering the lower side of the inner flange portion. As a lightweight dish having such a configuration, for example, Patent Document 2 discloses a paper dish for feeding pets in the outdoors under the name “pet feeding paper dish”. In addition, the idea which concerns on patent document 2 is convenient when feeding a pet in the outdoors etc. and carrying, and aims at becoming disposable. That is, the device according to Patent Document 2 is not intended to prevent the scattering of the dishes by the wind as in the present invention, but if the device according to Patent Document 2 is applied to solve the problem of the present invention, Whether or not the scattering prevention effect can be sufficiently exhibited will be examined below.

The pet feeding paper tray disclosed in Patent Document 2 includes an annular peripheral wall portion and a dish portion formed so as to dive in a semi-concave spherical shape inward and downward from the upper edge of the peripheral wall portion. The edge is grounded to the ground.
In the device having such a feature, it is considered that the invasion of wind between the peripheral wall portion and the dish portion is prevented because all the lower edges of the peripheral wall portion are in contact with the ground. Therefore, the device according to Patent Document 2 may be able to exhibit the above-described scattering prevention effect.

As a further problem, when using a plate outdoors, there are times when you want to temporarily place chopsticks, forks, and spoons (hereinafter referred to as chopsticks, etc.) on the plate. Because of its smoothness, there are things that slip and fall dirty when chopsticks are placed.
In order to solve this problem, a technique relating to simple tableware that can hold chopsticks and the like has already been developed. For example, in Patent Document 3, chopsticks and the like that are in use are simply left under the name “simple tableware” Disposable tableware is disclosed. The device disclosed in Patent Document 3 is a simple tableware formed of paper or styrofoam, and is characterized in that a notch or protrusion capable of temporarily holding chopsticks or the like is provided at one location on the outer periphery thereof.
In the device having such a feature, the handle or grip portion of chopsticks or the like can be easily inserted and held in the cuts and protrusions, so that it is possible to prevent the chopsticks or the like from dropping and becoming unusable.

However, in the device disclosed in Patent Document 2, it is strongly inclined linearly with respect to the ground in a side view from the upper edge to the lower edge of the peripheral wall portion. For this reason, when the wind blows from the lateral direction of the peripheral wall portion, the peripheral wall portion may be pushed in the wind traveling direction to slide on the table and fall from the edge.
Further, in the device disclosed in Patent Document 2, when the description is made by using the reference numerals used in FIG. 2 as it is, the tip portion 4a of the flange portion 4 is lifted from the ground 5, so that the wind and the flange portion 4 There is a possibility that the entire feeding tray 1 may be skipped by entering the gap in the ground 5.
Therefore, when the device according to Patent Document 2 is applied to solve the problem of the present invention, it may not be said that the scattering prevention effect can be sufficiently exhibited.
In addition, since the dish portion 3 is recessed in a hemispherical shape and the lowest outer bottom portion 3b may come into contact with the ground surface 5 as shown in FIGS. The bottom 3b becomes unclean and the feeding dish 1 cannot be turned over and used reversibly.

  Next, in the device disclosed in Patent Document 3, since the notches and protrusions are provided at one place on the outer peripheral edge of the simple tableware, it is necessary to fit chopsticks or the like into this one place notch or the like. Therefore, if chopsticks or the like are placed on the outer periphery without paying much attention to this point, there is a possibility that the chopsticks and the like cannot be held well. Further, when the protrusion is provided, the protrusion may be bent or extend in reverse as it is used, so that there is a possibility that the chopsticks or the like cannot be held.

  The present invention has been made in response to such a conventional situation, and is capable of preventing scattering and falling from the table regardless of the traveling direction of the wind while having a light and simple configuration. The purpose is to provide a lightweight dish that can be securely held even if it is placed untouched.

In order to achieve the above object, the first invention is a lightweight dish made of at least one of plant fiber, synthetic resin, and metal, and a placing part for placing food on the upper surface, and the placing part The side wall has a curved shape that is convex downward in a side view from the upper edge to the lower edge, and the lower edge is extended so that the entire circumference can contact the installation surface on which the lightweight dish is installed. It is characterized by that.
In the invention having such a configuration, since the entire periphery of the lower edge of the side wall is extended so as to be in contact with the installation surface on which the lightweight dish is installed, the position between the installation surface and the lower edge can be determined from any position on the lower edge. The wind is prevented from entering. For this reason, it is possible to prevent wind from entering between the installation surface and the mounting portion, and the lightweight dish is not struck and scattered or turned over.
In addition, since the side wall has a curved shape that protrudes downward in a side view from the upper edge to the lower edge, when the wind blows from the side of the side wall, the wind reaches the upper edge along the side wall. Ascend toward. Therefore, the wind blown from the side of the side wall quickly escapes over the upper edge to the upper side of the lightweight dish, so the lightweight dish is pushed in the direction of the wind and slides on the installation surface. It is prevented from falling.

Next, the second invention is characterized in that, in the first invention, the side wall is formed with a convex portion in a radial pattern around the center of the mounting portion.
In the invention having such a configuration, in addition to the action of the first invention, the convex portions are formed radially around the center portion of the placement portion, so that the fingers are convex portions or convex portions and convex portions. It has the effect | action that it is easy to be latched between parts.
In addition, with the above configuration, when wind blows from the side of the side wall, the wind flows between the convex portions and the convex portions, so that the wind is evenly rectified around the central portion of the placement portion.

Subsequently, according to a third invention, in the first or second invention, the bottom portion of the mounting portion is located at a height between the upper edge and the lower edge of the side wall in a side view, so that the upper edge and the lower edge When the upside down direction is reversed and turned upside down, a reversible structure is provided that allows food to be placed on the back surface of the top surface of the placement unit.
In the invention having such a configuration, the reversible structure does not change the shape of the lightweight dish itself, but instead of changing the shape of the lightweight dish upside down, instead of changing the shape of the lightweight dish, This also means that food can be placed on the back. Note that the food placed on the top surface of the placement portion and the food placed on the back surface of the placement portion may be different from each other or the same. In the present invention, the “side view” includes that the placing portion can be seen through from the side.
In the invention of the above configuration, in addition to the action of the first or second invention, the mounting portion is located at the height between the upper edge and the lower edge of the side wall in a side view, so that the bottom portion Does not always touch the installation surface. Therefore, even when the lightweight plate is turned upside down by reversing the vertical direction of the upper edge and the lower edge, the back surface of the mounting portion is kept clean.

Further, according to a fourth aspect of the present invention, in any one of the first to third aspects, the upper edge is a first repetitive structure in which the protruding portion is repeated or a groove portion is repeated in the side view. Or a third repeating structure in which protrusions and grooves are alternately repeated.
In the invention with such a configuration, the protruding portion is placed on a horizontal installation surface with the lower edge of the lightweight plate facing downward, and when viewed from the side, the height of the upper edge protrudes vertically upward. A portion refers to a portion where the height of the upper edge protrudes vertically upward in the same case.

In addition, as the first repeating structure, for example, a structure in which a plurality of protrusions having the same shape are repeated along the circumferential direction of the upper edge at intervals, a protrusion having a high height, There is a structure in which a set of arrays composed of low-groove portions connected to the protrusions is repeated along the circumferential direction of the upper edge. Furthermore, as the second repeating structure, for example, a plurality of groove portions having the same shape are repeated along the circumferential direction of the upper edge with a space between each other, or a deep groove portion, There is a structure in which a set of arrays each having a series of shallow grooves is repeated along the circumferential direction of the upper edge. As the third repeating structure, for example, a set of an array of a projecting portion and a groove portion connected to the projecting portion is repeated along the circumferential direction of the upper edge with or without spacing. There is a structure.
In the invention of the above configuration, in addition to the action of any one of the first to third inventions, in the first repetitive structure, chopsticks or the like are provided between the protrusions of the same shape or between the protrusions having a low height. Is locked. In the second repetitive structure, chopsticks or the like are locked in the groove portion having the same shape or the deep groove portion. In the third repeating structure, chopsticks or the like are locked in the groove. That is, in each of the above three repeating structures, protrusions or grooves are formed at a plurality of locations on the upper edge of the mounting portion, so that chopsticks or the like are either one of the plurality of protrusions or the plurality of grooves. It is locked without leaking.

  According to the first aspect of the present invention, since the wind is prevented from entering between the installation surface and the mounting portion and the lightweight dish does not scatter, it is possible to prevent surrounding contamination and waste of food. it can. Moreover, since the light plate is prevented from being pushed in the direction of the wind by the wind blown from the side of the side wall, the light plate can be prevented from being scattered and falling from the table regardless of the direction of the wind. .

According to the second invention, in addition to the effects of the first invention, since the finger is easily locked between the convex part or the convex part and the convex part, the entire circumference of the lower edge of the side wall contacts the installation surface. This makes it possible to eliminate the difficulty of holding.
Further, since the convex portions are formed radially around the center portion of the mounting portion, the wind blown from the lateral direction of the side wall is evenly rectified around the central portion of the mounting portion. For this reason, it is possible to prevent the disadvantage that the lightweight dish moves along the installation surface depending on the direction in which the wind has blown.

  According to the third invention, in addition to the effects of the first or second invention, the back surface of the mounting portion is clean even when the lightweight dish is turned upside down by reversing the vertical direction of the upper edge and the lower edge. Is maintained, food can be placed on both sides of the placement section. Therefore, it is convenient when the number of dishes is insufficient or when a food item that does not want to be mixed with the taste is ingested.

  According to the fourth invention, in addition to the effects of any one of the first to third inventions, the chopsticks and the like are locked in any one of the plurality of protruding portions or the plurality of groove portions. During the process, chopsticks can be placed on the upper edge of the side wall whenever necessary. In addition, even when chopsticks are placed unintentionally or when they are pushed by the wind, there is an advantageous effect that they do not fall and need not be replaced.

(A) is an external view at the time of carrying out the side view of the lightweight plate which concerns on the 2nd modification of an Example, (b) is a C line arrow view in (a). (A) is an external view at the time of carrying out the side view of the lightweight plate which concerns on the 3rd modification of an Example, (b) is a D line arrow directional view in (a).

The light weight dish which concerns on embodiment of this invention is demonstrated in detail using FIG. 1 thru | or FIG. Fig.1 (a) is an external view at the time of carrying out the side view of the lightweight plate which concerns on an Example, FIG.1 (b) is an A line arrow view in Fig.1 (a).
As shown to Fig.1 (a) and FIG.1 (b), the lightweight plate 1 which concerns on an Example is the lightweight plate which makes the circular shape made from paper which the whole consists of vegetable fiber.
The lightweight dish 1 includes a placement portion 2 for placing food on the upper surface 2 </ b> A, and a side wall 3 surrounding the placement portion 2.
Among these, the mounting portion 2 includes a bottom portion 2a having a flat surface without unevenness, and an inclined portion 2b that rises obliquely upward from the bottom portion 2a.
The side wall 3 has a curved shape that is convex downward in a side view from the upper edge 3a to the lower edge 3b, and the lower edge 3b contacts the installation surface 50 (see FIG. 2) on which the lightweight dish 1 is installed. It is extended as possible. That is, in the light dish 1, the gap between the entire circumference and the installation surface 50 of the lower edge 3b is not formed, from the position of the lower edge 3b throat, wind W ₁ enters the lower side of the mounting portion 2 It has a difficult structure. In addition, each part of the mounting part 2 and the side wall 3 is formed integrally by press-molding one paper material in the lightweight dish 1 of the said structure.

Specific dimensions of lightweight pan 1 has a diameter _{D 1} is 12cm of the upper edge 3a, the diameter _{D 2} is 18cm of the lower edge 3b, the diameter _{D 3} is 11cm bottom 2a of the mounting portion 2 projecting from the lower edge 3b section The height H ₁ to the top of 6 is 5 cm, and the height H ₂ from the lower edge 3 b to the bottom of the groove 7 is 4 cm. In this case, in a side view, the angle θ formed by the straight line L connecting one outermost point α of the upper edge 3a of the side wall 3 and one outermost point β of the lower edge 3b with respect to the lower edge 3b is about It is 50 degrees. Therefore, in order for the side wall 3 to have a downward convex curve from the upper edge 3a to the lower edge 3b, the angle at which the side wall 3 rises from the peripheral edge of the lower edge 3b needs to be smaller than about 50 degrees.

Moreover, as shown in FIG.1 (b), the side wall 3 forms the convex part 4 and the recessed part 5 alternately in the radial form every 20 degree | times centering on the center part 2c of the mounting part 2 near the upper edge 3a. Is done. In order to prevent the wind W ₁ from entering the lower side of the mounting portion 2, the concave portion 5 disappears near the lower edge 3 b of the side wall 3. However, the convex portion 4, as long as the wind W ₁ on the lower side of the mounting portion 2 can prevent the intrusion may not necessarily disappear at the position of the lower edge 3b closer. The boundary between the convex portion 4 and the concave portion 5 is a continuous and smooth curved surface.

Next, the configuration of the placement unit 2 will be described in more detail with reference to FIG. 2 (a) and 2 (b) are both external views when the lightweight dish according to the embodiment is viewed from the side, and FIG. 2 (a) is the installation surface of the lower edge of the lightweight dish according to the embodiment. FIG. 2 (b) shows a case where the lightweight pan according to the embodiment is used by turning the upper edge and the lower edge upside down and turning them upside down. In addition, about the component shown in FIG. 1, the same code | symbol is attached | subjected also in FIG. 2, and the description is abbreviate | omitted.
As shown in FIG. 2 (a), when the lower edge 3b of the side wall 3 is in contact with the installation surface 50 over the entire circumference, the mounting portion 2 of the lightweight dish 1 keeps the bottom 2a horizontal in a side view. And is located at a substantially middle height between the upper edge 3a and the lower edge 3b of the side wall 3. Therefore, as shown in FIG. 2 (b), when the lightweight pan 1 is turned upside down with the upper edge 3a and the lower edge 3b turned upside down, the placing portion 2 puts food on the back surface 2B of the upper surface 2A. Reversible structure that can be placed. At this time, the bottom part 2a is kept horizontal by all the parts which will be located in the lowest part among several protrusion parts 6 contacting the installation surface 50. FIG.

Further, the upper edge 3a of the side wall 3 will be described in detail with reference to FIGS. FIG. 3 is a perspective view illustrating a state in which chopsticks are temporarily placed on the upper edge of the lightweight plate according to the embodiment. 1 and 2 are denoted by the same reference numerals in FIG. 3 and description thereof is omitted.
As shown in FIGS. 1 and 2, the upper edge 3a has a third repetitive structure in which the protruding portions 6 and the groove portions 7 are alternately repeated so as to draw a sine curve in a side view. These protrusions 6 and grooves 7 are provided to lock chopsticks and the like on the upper edge 3a.
Further, the protrusion 6 is formed continuously above the protrusion 4, and the groove 7 is formed continuously above the recess 5. Therefore, as shown in FIG. 3, the protruding portion 6 has a curved surface shape having a constant area convex upward, and the groove portion 7 has a curved surface shape having a constant area convex downward. As a result, the chopsticks 51 are locked to the grooves 7 and 7 by bridging both ends of the chopsticks 51 at any two of the plurality of grooves 7.
As in the case of the convex portion 4 and the concave portion 5, the boundary between the protruding portion 6 and the groove portion 7 is a continuous smooth curved surface.

As shown in FIG. 1A, the lightweight dish 1 having the above configuration is configured such that the wind W ₁ does not easily enter the lower side of the placement portion 2 from any position on the lower edge 3b of the side wall 3. Yes. Therefore, it is prevented that the wind W ₁ enters between the installation surface 50 (see FIG. 2) and the placing portion 2, and the lightweight dish 1 is not beaten and scattered or turned over.
Further, since the side wall 3 has a curved shape that protrudes downward in a side view from the upper edge 3a to the lower edge 3b, when the wind W ₁ blows from the lateral direction of the side wall 3, the wind W ₁ Rises along the side wall 3 toward the upper edge 3a (arrow W ₂ ). Thus, the wind W ₁ is quickly released over the upper edge 3a and upward of the lightweight pan 1 (arrow W ₃ ). Therefore, as long as the wind W ₁ is not excessively strong, the lightweight dish 1 is pushed by the wind pressure in the traveling direction of the wind W ₁ and is prevented from sliding on the installation surface 50.

And in the light weight pan 1, as shown in FIG.1 (b), a convex part 4 and the recessed part 5 are radially formed centering on the center part 2c of the mounting part 2, and a finger | toe is convex part. 4 or the recess 5. Moreover, a finger can be locked also to the groove part 7. For this reason, when the lower edge 3b is used while being in contact with the installation surface 50, when the side wall 3 is held, the finger does not slip and the lightweight dish 1 is easily held.
Furthermore, in the above configuration, if the wind W ₁ from the lateral direction of the side wall 3 has been blown, from among the plurality of recesses 5, the wind W ₁ flows into any of those on the side of the wind W ₁ has been blowing. Further, the convex portion 4 and the recess 5 are evenly distributed around the central portion 2c, even when the wind W ₁ have blowing from either lateral, by the convex portion 4 and the recess 5 corresponding to the direction wind W ₁ is uniformly rectified about the central portion 2c. The direction in which the wind blows is actually different, but at least the wind W ₁ blown from the lateral direction of the side wall 3 has an effect of preventing scattering of the lightweight dish 1. Have.

In addition, since the bottom portion 2a of the mounting portion 2 is positioned at a height between the upper edge 3a and the lower edge 3b of the side wall 3 in a side view, the bottom portion 2a is brought into contact with the lower surface 3b. Since the bottom 2a is located at a height away from the installation surface 50, the bottom 2a is always installed on the installation surface. 50 does not touch. Therefore, the cleanliness of the top surface 2A and the back surface 2B is maintained both when the food is placed on the top surface 2A of the placement portion 2 and when the food is placed on the back surface 2B of the placement portion 2.
Moreover, the bottom part 2a of the mounting part 2 is maintained horizontally in any of the case where the lower edge 3b is brought into contact with the installation surface 50 and the case where the upper edge 3a is brought into contact with the installation surface 50.

As described above, according to the lightweight dish 1 according to the embodiment, the wind W ₁ is prevented from entering between the installation surface 50 and the placing portion 2, and the lightweight dish 1 is beaten and scattered, Since it does not tip over, it can prevent surrounding contamination and waste of food. Further, since the light weight pan 1 is pushed in the traveling direction by the wind pressure of the wind W ₁ from the lateral direction and is prevented from sliding on the installation surface 50, the light weight pan 1 is not scattered regardless of the traveling direction of the wind W _1. Can prevent falling.
Moreover, since the light tray 1 is formed by pressing a single sheet of paper, the mounting portion 2 and the side walls 3 are integrally formed. For this reason, it is possible to produce a large number of lightweight dishes 1 in a lump and provide them to consumers at low cost. Moreover, since the shape of the lightweight dish 1 is like Mt. Fuji and is aesthetic, it can be expected that the sales volume will be enhanced in particular in terms of design, which will motivate children, women or foreigners to purchase.

Furthermore, according to the light weight pan 1, since the finger is locked to the convex portion 4, the concave portion 5, or the groove portion 7, there is no trouble even though there is no gap between the lower edge 3b and the installation surface 50. The lightweight dish 1 can be lifted. On the other hand, when the upper edge 3a is used while being in contact with the installation surface 50, the lower edge 3b can be easily grasped, so that the lightweight dish 1 can be lifted without taking time and effort.
In addition, according to the lightweight dish 1, since the protrusion 6 and the groove 7 form a third repeated structure along the circumferential direction of the upper edge 3a, the chopsticks 51 and the like are attached to any two of the plurality of grooves 7. Can be locked in place. Therefore, the chopsticks 51 and the like can be placed on the upper edge 3a as needed during the meal, which is convenient. In addition, since the plurality of projecting portions 6 are provided along the circumferential direction of the upper edge 3a, even if the chopsticks 51 or the like are placed at random or pushed by the wind, they do not fall and can be replaced. This has the advantageous effect of not having to.

  And according to the lightweight plate 1, the bottom part 2a of the mounting part 2 is maintained horizontally in any of the case where the lower edge 3b is made to contact the installation surface 50, and the case where the bottom upper edge 3a is made to contact the installation surface 50. Therefore, the same or different foods can be stably placed on both the upper surface 2A and the back surface 2B of the placement portion 2, respectively. Therefore, for example, during outdoor barbecue, meat and vegetables are first placed with the upper surface 2A facing upward, and then the upper edge 3a and the lower edge 3b are turned upside down and turned over, and the rear surface 2B is facing upward. It is possible to use two roles with one sheet. The ability to use two roles in one piece is convenient for normal barbecue as described above, and in the event of a disaster, water for cleaning cannot be obtained due to water outage or the use of paper plates. This is particularly useful when the number of sheets is insufficient.

Next, a lightweight dish according to a first modification of the embodiment will be described with reference to FIG. Fig.4 (a) is an external view at the time of carrying out the side view of the lightweight plate concerning the 1st modification of an Example, FIG.4 (b) is a B line arrow view in Fig.4 (a). The constituent elements shown in FIGS. 1 to 3 are denoted by the same reference numerals in FIG. 4 and the description thereof is omitted.
As shown in FIGS. 4 (a) and 4 (b), a lightweight dish 1A according to a first modified example of the embodiment has a convex part 4 and a concave part 5 (see FIG. 1) constituting the lightweight dish 1 of the example. ) Is omitted, and the side wall 3 constituting the lightweight dish 1 and its upper edge 3a (see FIG. 1) are replaced with a side wall 8 having a smooth outer peripheral surface and a cylindrical upper edge 8a, respectively. is there. Among these, the side wall 8 forms an inclined surface that is uniformly inclined with respect to the circumferential direction of the side wall 8 with the central portion 2 c of the mounting portion 2 as the center. In addition, the upper edge 8a is replaced with a flat portion 9 in which the protruding portion 6 (see FIG. 1) of the lightweight plate 1 has a flat shape, and the groove portion 7 (see FIG. 1) of the lightweight plate 1 has a substantially U shape. It has been replaced with a notch 10.

Therefore, as shown in FIG. 4A, the upper edge 8a is formed along the circumferential direction of the upper edge 8a with a plurality of cutouts 10 having the same shape spaced apart from each other by a flat portion 9 in a side view. A second repeated structure is formed by repetition. Moreover, as shown in FIG.4 (b), the some flat part 9 and the some notch 10 are arrange | positioned so that it may respectively parallel in the direction corresponded to the string of the upper edge 8a. As a result, regions A ₁₀ (shaded portions) that linearly connect two of the plurality of cutouts 10 are formed at a plurality of locations, so that both ends of the chopsticks 51 and the like are attached to any one of these regions A _10. By being bridged, the chopsticks 51 and the like can be locked to the notches 10 and 10.
In addition, unlike the case of the protrusion part 6 and the groove part 7, the boundary of the flat part 9 and the notch 10 is clear. The other configuration of the lightweight dish 1A is the same as that of the lightweight dish 1 according to the embodiment.

In lightweight dish 1A of the above configuration, as shown in FIGS. 4 (a) and 4 (b), when the upper edge 8a is not in contact with the installation surface 50, chopsticks 51 or the like of the plurality of regions A ₁₀ Both are locked. Further, by grasping the upper edge 8 a instead of the convex portion 4 and the concave portion 5, the lightweight dish 1 </ b> A has an effect that it is easily held to the same extent as the lightweight dish 1.
In addition, since the light dish 1A does not include the convex part 4 and the concave part 5, the same rectifying action as that exerted by these parts is not exhibited, but the side wall 8 is centered on the central part 2c of the mounting part 2. since forming a uniform slope in the circumferential direction of the side wall 8, even when the wind W _{1 (see} FIG. 1) has been blowing from either lateral, a central portion 2c of the wind W ₁ is placing section 2 Ascending to the upper edge 8a along the side wall 8 as the center. The other operations of the lightweight dish 1A are the same as the operations of the lightweight dish 1 according to the embodiment.

As described above, according to the weight plates 1A, for chopsticks 51 or the like is locked both to the engagement also of the plurality of regions A _10, even casually when placed chopsticks 51 or the like reliably This can be held. Further, since the upper edge 8a can be gripped, it is easy to lift the lightweight dish 1A.
Furthermore, regardless of the traveling direction of the wind W _1, wind W ₁ is so raised toward the upper edge 8a evenly along the side walls 8 around the center 2c, it can prevent scattering or dropping of the weight plates 1A. Other effects of the lightweight dish 1A are the same as the effects of the lightweight dish 1 according to the embodiment.

And the lightweight plate which concerns on the 2nd modification of an Example is demonstrated using FIG. Fig.5 (a) is an external view at the time of carrying out the side view of the lightweight plate concerning the 2nd modification of an Example, FIG.5 (b) is a C line arrow directional view in Fig.5 (a). 1 to 4 are denoted by the same reference numerals in FIG. 5 and description thereof is omitted.
As shown in FIGS. 5 (a) and 5 (b), the light weight pan 1B according to the second modification of the embodiment has a convex portion 4 and a concave portion 5 (see FIG. 1) constituting the light weight pan 1 of the embodiment. ) Is omitted, and the side wall 3 constituting the lightweight dish 1 and its upper edge 3a (see FIG. 1) are replaced with a side wall 11 having a smooth outer peripheral surface and a cylindrical upper edge 11a, respectively. is there. Among these, the side wall 11 forms an inclined surface that is uniformly inclined with respect to the circumferential direction of the side wall 11 with the central portion 2 c of the mounting portion 2 as the center. Further, at the upper edge 11a, the protruding portion 6 (see FIG. 1) of the lightweight plate 1 is replaced with a protruding portion 12 protruding upward in a substantially U shape, and the groove portion 7 (see FIG. 1) of the lightweight plate 1 is flat.

Further, by grasping the upper edge 11 a instead of the convex part 4 and the concave part 5, the lightweight dish 1 </ b> B has an effect that it is easily held to the same extent as the lightweight dish 1.
Further, in the lightweight dish 1B, as in the lightweight dish 1A, the wind W ₁ is centered on the central portion 2c of the mounting portion 2 regardless of the lateral direction of the wind W ₁ (see FIG. 1). It rises along the side wall 11 toward the upper edge 11a. The other operations of the light weight dish 1B are the same as those of the light weight dish 1 according to the embodiment.

As described above, according to the lightweight dish 1B, the chopsticks 51 and the like are locked to any of the plurality of areas A ₁₃ and A ₁₃ ′. Even this can be held reliably. Further, since the upper edge 11a can be gripped, it is easy to lift the lightweight dish 1B.
Furthermore, in the light weight dish 1B, the light weight dish 1B can be prevented from being scattered or dropped in the same manner as the light weight dish 1A. Other effects of the lightweight dish 1B are the same as the effects of the lightweight dish 1 according to the embodiment.

Finally, a lightweight dish according to a third modification of the embodiment will be described with reference to FIG. Fig.6 (a) is an external view at the time of carrying out the side view of the lightweight plate concerning the 3rd modification of an Example, FIG.6 (b) is a D line arrow view in Fig.6 (a). The components shown in FIGS. 1 to 5 are denoted by the same reference numerals in FIG. 6 and the description thereof is omitted.
As shown in FIGS. 6A and 6B, a lightweight dish 1C according to a third modification of the embodiment includes a side wall 3 and an upper edge 3a (see FIG. 1) are replaced by the side wall 14 and the upper edge 14a, respectively. Among these, in the side wall 14, the convex part 4 (refer FIG. 1) provided in the side wall 3 of the lightweight dish 1 is substituted by the plate-shaped protrusion piece 15, and the recessed part 5 (refer FIG. 1) of the side wall 3 is abbreviate | omitted. ing. Further, the protruding piece 15 is formed in a radial shape every 30 degrees with the center portion 2c of the placement portion 2 as the center. And in the upper edge 14a, the protrusion part 6 and the groove part 7 (refer FIG. 1) in the upper edge 3a are abbreviate | omitted. The other configuration of the lightweight dish 1C is the same as that of the lightweight dish 1 according to the embodiment.

As shown in FIG. 6 (a), the lightweight plate 1C having the above-described configuration has a flat upper edge 14a in a side view. It is.
In addition, since the fingers are locked to the projecting pieces 15 by forming the projecting pieces 15 radially around the center portion 2c of the mounting portion 2, the fingers do not slip when having the side wall 14, and the lightweight dish 1C Has the effect of being easily held.
Furthermore, in the above arrangement, if that has winds W ₁ from the lateral direction of the side wall 3 _(see FIG. 1), the wind flows between the projecting pieces 15 and the projecting pieces 15, blowing wind W ₁ from either lateral even if has, wind W ₁ by the projecting piece 15 corresponding to that direction is uniformly rectified about the central portion 2c. Therefore, in the light dish 1C, similarly to the light dish 1A, the wind W ₁ is equally distributed along the side wall 14 around the center part 2c of the mounting part 2 regardless of the direction in which the wind W ₁ blows. It rises toward the edge 14a. The other operations of the light weight dish 1C are the same as the actions of the light weight dish 1 according to the embodiment.

As described above, according to the lightweight dish 1C, since the protruding piece 15 can be gripped, it is easy to lift the lightweight dish 1C.

Moreover, scattering and falling of the lightweight dish 1C can be prevented. Other effects of the lightweight dish 1C are the same as the effects of the lightweight dish 1 according to the embodiment.

In addition, the lightweight dishes 1 and 1A-1C which concern on this invention are not limited to what is shown in an Example. For example, in the light weight pan 1, in a side view, the protruding portion 6 and the groove portion 7 are repeated so as to draw a rectangular wave or a triangular wave along the circumferential direction of the upper edge 3 a instead of drawing a sine curve. Also good. Further, the bottom portion 2a of the mounting portion 2 does not necessarily have to be located at a substantially middle height between the upper edge 3a and the lower edge 3b as long as it is between the upper edge 3a and the lower edge 3b of the side wall 3. May be formed, or may be slightly curved. On the contrary, when the bottom part 2a of the mounting part 2 descends to the same height as the lower edge 3b of the side wall 3, the lightweight dish 1 may not have a reversible structure.
Furthermore, each of the lightweight dishes 1 and 1A to 1C may be made of plastic or aluminum instead of being made of paper, and may have a polygonal shape or an elliptical shape instead of a circular shape. Moreover, depending on the dimension of each part which comprises the lightweight dishes 1, 1A-1C, the angle which the side walls 3, 8, 11, 14 stand up from the periphery of the lower edge 3b may be other than about 50 degree | times, respectively.
