TECHNICAL FIELD The present invention relates to a bamboo tableware which is provided with ridges as partitions curved inward, which makes it easy to scoop up foodstuffs, allows children to eat without getting bored, and which has high durability, and a method for making the bamboo tableware.

Bamboo tableware, which is cut from wood and molded, is light and easy to handle, and the bamboo material has antibacterial properties and is hygienic, so it is widely used for tableware for infants.

Bamboo tableware for infants is widely distributed as a plate type tableware in which a bank-like partition is provided on the upper surface of the plate. By partitioning with bank-like partitions, it is possible to serve a large variety of dishes in small amounts and provide meals with good nutritional balance. However, plate-type tableware is difficult for infants who are unfamiliar with using cutlery such as spoons because the food tends to spill out of the spoon when they scoop it up. In addition, since infants get bored quickly, it is necessary to devise ways to attract the interest of infants so that they can eat until the end without getting bored.

Patent Document 1 is a tableware for infants provided with a lid with an opening. When food is scooped with a spoon and the spoon is taken out through the opening, an easy-to-eat amount is placed on the spoon, and the infant can lift the spoon by himself. It is devised so that you can use it to eat well.

The tableware for infants of Patent Document 1 has the convenience of being able to scoop up a certain amount of food with a spoon, but only one type of food can be put in the container, and infants who get bored easily stop eating in the middle of the meal. I often end up doing it. In addition, deep tableware with a lid makes it difficult for children to see the food inside, which makes it difficult for young children to take an interest in eating.

To provide a plate-type tableware on which a plurality of kinds of dishes are placed so that the dishes look good and can be easily scooped up with a spoon.

The bamboo tableware of the present invention comprises a substantially flat food placement portion for storing food, a side portion rising upward from the outer periphery of the circular food placement portion, and an upper portion from above the food placement portion. and a bank-like ridge that rises toward the center of the side surface and curves toward the outer end from the center of the side surface.

According to this invention, since the ridges that are the partitions curved inward are provided, it is easy to scoop up the food by sliding the spoon along the ridges. The shape of the ridge is a novel design that combines curved lines, so that infants can eat without getting bored.

Further, the food placement part of the bamboo tableware of the present invention forms at least two food placement compartments separated by the ridge, the ridge having a plurality of inward curves, Characterized by different curves

According to the present invention, the food placement section has at least two compartments surrounded by curved lines partitioned by the ridges, and each compartment has a plurality of different radiuses facing inward. Since it has a curve, it is possible to scoop up food of any size and shape with the spoon by inserting the spoon into the curved portion and sliding it. Infants and toddlers can learn how to use cutlery and receive the training they need to learn to eat on their own.

In addition, the side portion of the bamboo tableware of the present invention is provided with a stepped portion along the outer circumference near the center thereof, and the diameter of the circle formed by the projecting portion of the outer stepped portion is equal to the diameter of the side portion The diameter of the circle formed by the edge near the center of the upper edge of the side is larger than the diameter of the circle formed by the boundary between the outer stepped portion and the side portion. is smaller than the diameter of the circle formed by the edge near the center.

According to this invention, the side surface portion has a step along the outer periphery near the center, and the diameter of the circle formed by the projecting portion of the outer step portion is the center of the upper edge of the side surface portion. The diameter of the circle formed by the boundary between the outer stepped portion and the side portion is larger than the diameter of the circle formed by the edge near the side portion, and the diameter of the circle formed by the boundary portion between the outer stepped portion and the side portion is the edge near the center of the upper edge of the side portion. Since it is smaller than the diameter of the circle formed by the above, when a plurality of bamboo tableware are stacked on top of each other, the part below the step on the outside of the side part fits in the bamboo tableware stacked below, and The portion above the step on the outer side of the side portion rests on the side portion of the bamboo tableware stacked below. That is, the upper bamboo tableware does not get stuck in the lower bamboo tableware, and the bamboo tableware can be neatly stacked while maintaining an appropriate space. Even a small child can easily stack the tableware, so that the cleanup work can be enjoyed and the importance of cleanup afterward can be learned.

Further, the bamboo tableware of the present invention is characterized in that the height from the step to the lower end of the side portion is half or less of the height from the lower end to the upper end of the side portion.

According to this invention, the height from the step to the lower end of the side portion is half or less than the height from the lower end to the upper end of the side portion. The back surface of the bamboo tableware stacked on top of each other does not come into contact with the inner bottom surface of the lower bamboo tableware. Therefore, the food remaining on the inner bottom surface of the lower bamboo tableware does not adhere to the back surface of the upper bamboo tableware, and even if the bamboo tableware is piled up and transported after a meal, the bamboo tableware can be kept clean. can be minimized. In addition, when storing bamboo tableware before use, dirt and germs on the back side of the bamboo tableware stacked on top do not adhere to the inner bottom of the tableware where food is to be placed, so bamboo tableware can be stored cleanly before use. can do.

In addition, in the method for making bamboo tableware of the present invention, the process of shaving and molding a bamboo material using bamboo joints, applying a urethane coating to the surface of the main body, and drying it is repeated at least three times and then polished. It is characterized by molding by repeating the process multiple times.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the best mode for carrying out the invention will be described with reference to the accompanying drawings.

(Embodiment 1)
As shown in FIG. 1, the bamboo tableware 100 includes a substantially flat food placement portion 3 on which food is placed, a side portion 4 rising upward from the outer circumference of the circular food placement portion 3, A rim portion 2 provided on the side surface portion 4 and having a plane parallel to the floor surface on the upper side; It mainly has a bank-like ridge 1 that is provided so as to draw curves in three directions from the center of the placing portion 3 toward the outer end. The food placement portion 3, the ridge portion 1, the rim portion 2, the side portion 4, and the bottom surface 5 are integrally cut out from a bamboo block. The bamboo block is made by splitting bamboo in the direction of the long sides and forming square prisms into a flat plate shape by arranging them horizontally, stacking the flat plates so that the bamboo conduit directions are perpendicular to each other, and crimping and bonding them to form a block shape. Use what you have. By stacking flat plates so that the directions of the bamboo conduits are alternated, the bamboo blocks can withstand both vertical and horizontal loads, increasing durability.

In addition, the bamboo tableware 100 is formed by shaving a bamboo block, and then applying a urethane coating film on the tableware surface and drying it, which is repeated at least three times. When the bamboo tableware of the present invention is carved from a bamboo block, the shape of the blade is devised so that the bamboo joints are also carved. After the drying process, the process of polishing the tableware surface is also performed multiple times. In the polishing process, first, coarse-grained sandpaper is used for polishing, and then fine-grained sandpaper is gradually changed to perform polishing multiple times. A polishing step may be interposed each time the urethane coating layer is applied and dried, or a polishing step may be interposed after the step of applying and drying the urethane coating layer is repeated multiple times. By repeating the process of applying and drying the urethane coating film and the polishing process a plurality of times, the urethane coating can be deeply penetrated into the bamboo material, and the bamboo tableware 100 with high durability can be obtained. Furthermore, although the joints of bamboo are hard and robust and the unit price of the material is low, the cross section of the bamboo conduit is exposed on the surface and is porous, so it is easy for mold to grow and cracks to form from the conduit. However, since this bamboo tableware 100 has undergone multiple urethane coating processes, drying processes, and multiple polishing processes, the urethane coating penetrates deep into the bamboo pipes, and the surface of the tableware is coated with urethane. Since it is protected, the robust bamboo tableware 100 is hard to grow mold and hard to crack.

As shown in FIG. 2, the bamboo tableware 100 is partitioned into three food placement compartments 3 by the ridges 1 in plan view. Ridge portion 1 rises upward from food placement portion 3 . The ridge 1 has at least one curve directed inward and one curve directed outward, and is provided so as to draw curves in three directions outward from the center. The food placement compartment 3 has three curves, a first curve 31 , a second curve 32 and a third curve 33 . The first curve 31 is the steepest curve among the three curves and is provided near the outer end of the bamboo tableware 100 . The second curve 32 is a curve provided near the center and is gentler than the first curve. The third curve 33 is provided near the outer end of the bamboo tableware 100 and adjacent to the first curve 31 of the adjacent food placement section 3 . The third curve is a curve that is gentler than the second curve, has a small radius, and is a gentle curve like a curve. Since the ridge 1 is curved in a top view, warping of the bamboo material is prevented and the strength is increased.

The first curve 31 has a shape along the curve of the tip of the infant spoon. As shown in FIG. 3, the first curve 31 is a curve provided at the outer end of the bamboo tableware 100, and is the steepest curve among the three curves, and the width of the food placement portion 3 is also narrow. Therefore, when the food placed on the bamboo tableware 100 is placed on the spoon and the spoon is slid along the ridge 1 to the vicinity of the first curve 31, an appropriate amount of food is placed on the spoon. It will be loaded. The radius of the first curve 31 (R in FIG. 3) is the radius drawn by the boundary line between the bottom surface of the food placement portion 3 and the ridge portion 1, and the radius of the first curve 31 is the size of the infant spoon. It is almost the same as the radius dimension of the tip. Therefore, with the food on the spoon, slide the spoon to the vicinity of the first curve 31, and when the tip of the spoon reaches the inner wall of the ridge 1, move the spoon upward along the inner wall of the ridge 1. You can scoop a mouthful of food skillfully with a spoon.

In the bamboo tableware 100 of Embodiment 1, the width of the ridge 1 is 2 mm or more and 20 mm or less. Desirably, it should be 3 mm or more and 6 mm or less. If the width of the ridges 1 is too large, the weight of the wooden tableware 100 will be too large, making it unsuitable for infants to support with their hands. If it is too thin, the durability becomes weak, and the ridges 1 are easily damaged during cutting. The bamboo tableware 100 is produced by shaving molding, but since the shape of the ridge 1 is formed only by curved lines, when scooping up with a spoon, the spoon may be caught in the middle, and food may be rubbed on the spoon. Food is rarely spilled during the process of moving, and food can be easily scooped up with natural movements.

As shown in FIG. 4 , the bamboo tableware 100 has a base 51 on the bottom surface 5 . With the provision of the foot 51, when the bamboo tableware 100 is placed on a horizontal surface such as a table, the bottom surface 5 does not come into close contact with the entire surface and forms an appropriate space, allowing moisture to escape and the bottom surface of the bamboo tableware 100. dries, prevents mildew, and increases durability.

As shown in FIGS. 5 and 6, the bamboo tableware 100 has a gentle curve on the inside of the side surface 4 in a cross-sectional view, and an outer stepped portion 41 on the outside. The outer stepped portion 41 is a stepped portion having rounded corners and provided along the outer circumference of the tableware. The bamboo tableware 100 is a circular plate in plan view, and the side surface portion 4 is provided with a stepped portion along the outer periphery near the center thereof to form an outer stepped portion 41 . The diameter of the circle formed by the projecting portion of the outer stepped portion 41 (e in FIG. 5) is the diameter of the circle formed by the edge 42 near the center of the upper edge of the side surface portion 4 (e in FIG. 5). d), the diameter of the circle formed by the boundary 43 between the outer stepped portion 41 and the side surface 4 (c in FIG. 5) is the edge near the center of the upper edge of the side surface 41. 42 is smaller than the diameter dimension of the circle (d dimension in FIG. 5).

Therefore, when a plurality of bamboo tableware 100 are stacked on top of each other, the portion below the outer stepped portion 41 fits inside the stacked bamboo tableware, and the portion above the outer stepped portion 41 is It is placed on the side part 4 of the bamboo tableware 100 stacked below. As shown in FIGS. 7 and 8, when a plurality of bamboo tableware 100 are piled up, the upper bamboo tableware 100 does not get stuck in the lower bamboo tableware 100, and the bamboo tableware 100 is neatly stacked while maintaining an appropriate space. be able to. The wooden tableware 100 can be easily piled up even by an infant.

In addition, since the height from the outer stepped portion 41 of the side portion 4 of the bamboo tableware 100 to the bottom surface is less than half the height of the side portion 4 of the bamboo tableware 100, the bamboo tableware 100 can be moved up and down. When stacked, the bottom surface 5 of the bamboo tableware 100 does not come into contact with the food placement part 3 of the bamboo tableware 100 stacked below, forming an appropriate space inside. A plurality of bamboo tableware 100 can be hygienically stacked without the food placement part 3 touching the outside of the adjacent bamboo tableware 100, which is convenient for storage and transportation. Since food remaining on the inner bottom surface of the lower bamboo tableware 100 does not adhere to the back surface of the upper bamboo tableware 100, the bamboo tableware 100 can be stacked even when the bamboo tableware 100 is transported after a meal. contamination can be minimized. Also, when the bamboo tableware 100 is stored before use, the bamboo tableware 100 before use does not adhere to the inner bottom surface of the tableware into which food is to be placed, since the back surface of the bamboo tableware 100 stacked on top does not adhere. It can be kept clean.

As shown in FIG. 9, the bamboo tableware 100 has the ridges 1 formed in a curved shape, so that it is visually easy to stack a plurality of bamboo tableware 100 after eating. . Even a small child can skillfully stack up and down by adjusting the direction while looking at the curved shape of the ridge 1.例文帳に追加Since the bamboo tableware 100 can be piled up and put away just like putting together a puzzle, even a small child can enjoy and easily carry out the work.

As shown in FIG. 10, the bamboo tableware 100 has three food placement compartments partitioned by the ridges 1, each compartment having a first curve 31, a second curve 32, and a third curve having different shapes. Since there are three curves 33 and three curves, an infant can eat while considering in which direction the spoon should be slid to scoop up the food according to the size of the food and the size of the spoon. But you can enjoy your meal without getting bored. Large lumps are scooped by sliding the spoon in the direction of the third curve 33, which is a gentle curve. To increase a child's willingness to eat by eating while thinking, such as eating with a large spoon or scooping up easily spillable food by sliding the spoon in the direction of a second curve 32 near the center. can be done.

The bamboo tableware 100 of Example 1 is a circular tableware with a diameter of 23 cm, the first curve 31 is the curve with the smallest R value, and the third curve 33 is the curve with the largest R value. A first curve 31 , a second curve 32 , and a third curve 33 are curves drawn by curves at the boundary between the bottom surface of the food placement portion 3 and the ridge portion 1 . The R value of the second curve 32 is larger than the R value of the first curve 31 and smaller than the R value of the third curve 33. In the bamboo tableware 100 of Example 1, the R value of the first curve 31 is about 3 mm. Yes, and the R value of the second curve 32 is approximately 7.5 millimeters. The R value of the second curve 32 is desirably 4 times or more and 6 times or less of the R value of the first curve 31 . Since the third curve 33 is adjacent to the first curve 31 , it varies depending on the diameter of the tableware body and the R value of the first curve 31 .

The bamboo tableware 100 of the present invention performs uniform laser engraving with a laser output that matches the shade of the main body surface. Natural materials such as bamboo have slight differences in water content, hardness, and color at each part, making it difficult to engrave uniformly and accurately. Laser engraving. The color of the marking of the bamboo tableware 100 is made uniform by increasing the laser output for the dark colored part of the bamboo material and engraving firmly, and by suppressing the laser output and engraving the light colored part of the bamboo material.
