Description

The present invention relates to a bamboo tableware and a method for producing bamboo tableware, which are provided with ridges that are curved partitions on the inside, are easy to scoop up foodstuffs, allow infants to eat without getting tired, and have high durability.

Bamboo tableware, which is formed by cutting out wood, 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 plate-type tableware with a bank-shaped partition on the upper surface of the plate. By separating with a bank-shaped partition, it is possible to serve many kinds of dishes little by little and provide a nutritionally balanced meal. However, plate-type tableware is difficult for infants who are not accustomed to using cutlery such as spoons because food tends to spill from the spoon when scooping with a spoon. In addition, since infants get bored quickly, it is necessary to devise ways to attract the interest of infants when eating so that they can eat to 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 alone puts the spoon. It is devised so that you can use it and eat well.

Japanese Unexamined Patent Publication No. 2004-255085

While the infant tableware of Patent Document 1 has the convenience of being able to scoop a certain amount of food with a spoon, there is only one type of food to put in a container, and a tired infant gets tired and interrupts in the middle of a meal. I often end up doing it. In addition, deep tableware with a lid makes it difficult for infants to be interested in eating because the food inside cannot be seen well.

The present invention provides a plate-type tableware on which a plurality of types are placed so that the dish looks good and is easy to scoop with a spoon.

The bamboo tableware of the present invention has a substantially flat food storage portion for accommodating food, a side surface portion that rises upward from the outer periphery of the circular food storage portion, and an upper portion from above the food storage portion. It is characterized by having a bank-shaped ridge portion that rises toward the surface and is provided so as to draw a curve toward the outer end starting from the center of the side surface portion.

According to the present invention, since the ridge portion which is a partition curved inward is provided, it is easy to scoop up the food material by sliding the spoon along the ridge portion. The shape of the ridge is a novel design that combines curves, so that infants can eat without getting tired.

Further, the food placing portion of the bamboo tableware of the present invention forms at least two food placing portions separated by the ridges, and the ridges have a plurality of inward curves, and the above-mentioned Characterized by different radius of the curve

According to the present invention, the food placing section has at least two sections surrounded by a curve by being partitioned by the ridges, and each section faces a plurality of inward parts having different sizes of radius. Since it has a curve, by inserting a spoon into the curved part and sliding it, food of any size and shape can be scooped up well with the spoon. Infants can learn how to use cutlery and provide the necessary training to be able to eat alone.

Further, in the side surface portion of the bamboo tableware of the present invention, the side surface portion is provided with a step along the outer periphery in the vicinity of the center, and the diameter of the circle formed by the protruding portion of the outer step portion is the diameter of the side surface portion. The diameter of the circle formed by the boundary between the outer step portion and the side surface portion is larger than the diameter of the circle formed by the edge portion of the upper edge portion near the center, and the diameter of the circle formed by the boundary portion between the outer step portion and the side surface portion is the upper edge portion of the side surface portion. It is characterized in that it is smaller than the diameter of the circle formed by the edge near the center.

According to the present invention, the side surface portion is provided with a step along the outer periphery in the vicinity of the center, and the diameter of the circle formed by the protruding 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 step portion and the side surface portion is larger than the diameter of the circle formed by the edge portion close to the portion, and the diameter of the circle formed by the boundary portion between the outer step portion and the side surface portion is the end edge closer to the center portion of the upper edge portion of the side surface portion. Since it is smaller than the diameter of the circle formed by, when multiple bamboo tableware are stacked on top of each other, the part below the step on the outside of the side surface fits in the bamboo tableware stacked underneath. The part above the step on the outside of the side surface rests on the side surface of the bamboo tableware stacked underneath. That is, the upper bamboo tableware does not fit into the lower bamboo tableware, and can be stacked neatly while maintaining an appropriate space. Even infants can easily stack tableware, so cleaning up can be fun and you can learn the importance of cleaning up afterwards.

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

According to the present invention, the height from the step to the lower end of the side surface portion is less than half the height from the lower end to the upper end of the side surface portion. The back side of the bamboo tableware stacked on top of the table does not touch 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 stacked and transported after meals, the bamboo tableware will be soiled. Can be minimized. Also, when storing bamboo tableware before use, dirt and germs on the back side of the bamboo tableware stacked on the upper side will not adhere to the inner bottom surface of the tableware to which food will be put, so keep the bamboo tableware before use clean. can do.

Further, in the method for producing bamboo tableware of the present invention, the steps of carving and molding from a bamboo material using bamboo knots, applying a urethane coating film to the surface of the main body, and drying are repeated at least three times and polished. It is characterized by repeating the process a plurality of times for molding.

According to the present invention, since the hard portion of the bamboo knot is machined and molded, it is possible to provide a sturdy and durable bamboo tableware. The knots of bamboo are hard and robust, and the unit price of the material is low. The bamboo tableware of the invention has undergone multiple urethane coating steps, drying steps, and multiple polishing steps, so even if the bamboo knots are used, the surface is smooth and completely protected by the urethane coating. It is hard to grow mold and cracks.

Further, the method for producing bamboo tableware of the present invention is characterized in that uniform laser engraving is performed with a laser output that matches the shade of the surface of the main body.

Since the water content, hardness, and color of each part of natural materials such as bamboo are slightly different, it is difficult to engrave them uniformly and accurately express them. Since laser engraving is performed, uniform and beautiful engraving can be engraved on the surface.

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 placing portion 3 on which food is placed, and a side surface portion 4 rising upward from the outer periphery of the circular food placing portion 3. The rim portion 2 provided on the side surface portion 4 and having a plane parallel to the floor surface on the upper side, and the food loading portion 3 provided on the food placing portion 3 and inside the side surface portion 4 are provided. It mainly has a bank-shaped ridge 1 provided so as to draw a curve in three directions from the center of the placement portion 3 toward the outer end. The food placing portion 3, the ridge portion 1, the rim portion 2, the side surface portion 4, and the bottom surface 5 are integrally carved from the bamboo block. The bamboo block is made by splitting bamboo material in the long side direction to form a square pillar shape by arranging the prisms horizontally to form a flat plate shape. Use the one that has been used. By stacking the flat plates so that the directions of the bamboo conduits are staggered, the bamboo block can withstand both vertical and horizontal loads, and durability can be improved.

Further, the bamboo tableware 100 is machined from a bamboo block, and then the process of applying a urethane coating film to the tableware surface and drying the tableware 100 is repeated at least three times. In the bamboo tableware of the present invention, when cutting from a bamboo block, the shape of the blade is devised so that the bamboo knots are also carved. After the drying process, the process of polishing the tableware surface is also performed multiple times. In the polishing process, first polish with coarse sandpaper, then gradually change to fine sandpaper and polish multiple times. A polishing step may be sandwiched each time the urethane coating film layer is applied and dried, or a polishing step may be sandwiched after the steps of applying and drying the urethane coating film layer are repeated a plurality of times. By repeating the process of applying the urethane coating film and drying it a plurality of times, the urethane paint can be penetrated deep into the bamboo material to obtain a highly durable bamboo tableware 100. Furthermore, while the bamboo knots are hard and robust and the unit price of the material is low, the bamboo conduit cross section is exposed on the surface and is porous, so it is easy for mold to grow and cracks are likely to occur from the conduit part. However, since this bamboo tableware 100 has undergone multiple urethane coating steps, drying steps, and multiple polishing steps, the urethane paint penetrates deep into the bamboo conduit and the tableware surface is coated with urethane. Since it is protected, it can be made into a robust bamboo tableware 100 that is resistant to mold growth and cracking.

As shown in FIG. 2, the bamboo tableware 100 is divided into three food storage compartments 3 by the ridges 1 in a plan view. The ridge 1 stands up from above the food placing portion 3. The ridge 1 has at least one curve toward the inside and a curve toward the outside, and is provided so as to draw a curve in three directions from the center to the outside. The food storage 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 a gentler curve than the first curve. The third curve 33 is provided near the outer end of the bamboo tableware 100 and at a position adjacent to the first curve 31 of the adjacent food storage section 3. The third curve is a curve that is even looser than the second curve, has a small radius, and is a gentle curve like a curve. Since the ridge 1 is curved in a curved shape when viewed from above, the bamboo material is prevented from warping and its 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 placing portion 3 is also wide. It's getting narrower. 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 in the state of being placed. 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 placing portion 3 and the ridge portion 1, and the radius dimension of the first curve 31 is that of the infant spoon. It is almost the same as the rounded dimension of the tip. Therefore, with food on the spoon, slide the spoon to the vicinity of the 31st part of the first curve, and when the tip of the spoon reaches the inner wall of the ridge 1, raise the spoon along the inner wall of the ridge 1. If you lift it up, you can scoop up a bite of food with a spoon.

In the bamboo tableware 100 of the first embodiment, the width of the ridge 1 is 2 mm or more and 20 mm or less. Desirably, it is 3 mm or more and 6 mm or less. If the width of the ridge 1 is too thick, the weight of the wooden tableware 100 becomes large and it is not suitable for an infant to support by hand. If it is too thin, the durability will be weakened, and the ridge 1 will be easily damaged during cutting. Bamboo tableware 100 is made by machined molding, but since the shape of the ridge 1 is formed only by curves, when scooping up with a spoon, the spoon may get caught in the middle, or food may be placed on the spoon and rubbed. Food is less likely to spill during the process of movement, and you can easily scoop food with natural movements.

As shown in FIG. 4, the bamboo tableware 100 is provided with a hill 51 on the bottom surface 5. Due to the provision of the hill 51, when the bamboo tableware 100 is placed on a horizontal surface such as a table, the entire bottom surface 5 does not adhere to each other and forms an appropriate space, so that moisture can escape and the bottom surface of the bamboo tableware 100 can be released. Can be dried to prevent mold and increase durability.

As shown in FIGS. 5 and 6, in the bamboo tableware 100, a gentle curve is formed on the inside of the side surface portion 4 in a cross-sectional view, and an outside step portion 41 is provided on the outside. The outer step portion 41 is a rounded corner and is a step provided along the outer circumference of the tableware. The bamboo tableware 100 is a circular plate in a plan view, and the side surface portion 4 is provided with a step along the outer periphery in the vicinity of the center to be an outer step portion 41. The diameter of the circle formed by the protrusion of the outer step 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 (FIG. 5). The diameter of the circle (c in FIG. 5) formed by the boundary portion 43 between the outer step portion 41 and the side surface portion 4 which is larger than d) is the edge closer to the center of the upper edge of the side surface portion 41. It is smaller than the diameter dimension (d dimension in FIG. 5) of the circle formed by 42.

Therefore, when a plurality of bamboo tableware 100 are stacked on top of each other, the portion below the outer step portion 41 fits in the bamboo tableware stacked underneath, and the portion above the outer step portion 41 is formed. It is placed on the side surface 4 of the bamboo tableware 100 stacked underneath. As shown in FIGS. 7 and 8, when a plurality of bamboo tableware 100 are stacked, the upper bamboo tableware 100 does not fit into the lower bamboo tableware 100, and the bamboo tableware 100 is neatly stacked while maintaining an appropriate space. be able to. Even infants can easily stack tableware on the wooden tableware 100.

Further, since the height from the outer step portion 41 of the side surface portion 4 of the bamboo tableware 100 to the bottom surface is less than half the height of the side surface portion 4 of the bamboo tableware 100, the bamboo tableware 100 is moved up and down. The bottom surface 5 of the bamboo tableware 100 does not come into contact with the food placing portion 3 of the bamboo tableware 100 stacked underneath, and forms an appropriate space inside. The food placing portion 3 does not touch the outside of the adjacent bamboo tableware 100, and a plurality of bamboo tableware 100 can be hygienically stacked, which is convenient for storage and transportation. Since the 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, even if the bamboo tableware 100 is stacked and transported after a meal, the bamboo tableware 100 Dirt can be minimized. In addition, when the bamboo tableware 100 is stored before use, dirt and germs on the back surface of the bamboo tableware 100 stacked on the upper side do not adhere to the inner bottom surface of the tableware to which food is to be put. Can be stored cleanly.

As shown in FIG. 9, since the ridges 1 of the bamboo tableware 100 are provided in a curved shape, it is easy to visually stack the bamboo tableware 100 when the plurality of bamboo tableware 100 are stacked after the meal is finished. .. Even infants can stack up and down well by looking at the curved shape of the ridge 1 and adjusting the direction. Bamboo tableware 100 can be stacked and tidied up as if fitting a puzzle, so even infants can enjoy and easily tidy up.

As shown in FIG. 10, the bamboo tableware 100 has three food storage compartments partitioned by the ridges 1, and the first curve 31, the second curve 32, and the second curve having different curve shapes are in each compartment. Since there are three curves 33 and three curves, depending on the size of the food and the size of the spoon, it is possible to eat while thinking about which curve direction to slide the spoon to scoop up the food well. 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 of the loose curve, and watery foods and fine foods are scooped by sliding the spoon in the direction of the first curve 31 of the sharp curve. When eating with a large spoon, or for spillable food, slide the spoon in the direction of the second curve 32 near the center to scoop up, and eat while thinking to increase the motivation of infants to eat. Can be done.

The bamboo tableware 100 of the first embodiment is a circular tableware having a diameter of 23 cm, the first curve 31 is the curve having the smallest R value, and the third curve 33 is the curve having the largest R value. The first curve 31, the second curve 32, and the third curve 33 are rounds drawn by the curves of the boundary portion between the bottom surface of the food placing portion 3 and the ridge portion 1, respectively. In the bamboo tableware 100 of Example 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, the R value of the first curve 31 is about 3 mm. Yes, the R value of the second curve 32 is about 7.5 mm. It is desirable that the R value of the second curve 32 is 4 times or more and 6 times or less 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 surface of the main body. Since the water content, hardness, and color of each part of natural materials such as bamboo are slightly different, it is difficult to engrave them uniformly and accurately express them. Laser engraving is performed. The dark part of the bamboo material has a high laser output and is firmly engraved, and the light part of the bamboo material is engraved with the laser output suppressed to make the color of the engraving on the bamboo tableware 100 uniform.
