  The partition plates 22 and 23 form accommodating portions 2 a, 2 b, and 2 c that have a one-to-one relationship with the volume inside the box body 21. Seven types of the second lunch box 2 are set in which the volumes of the accommodating portions 2a, 2b, and 2c are different so as to cope with the difference in calorie intake due to the difference in the height, weight or labor level of the user.

  In addition, on the upper surface of the bottom wall 21a of each of the accommodating portions 2a, 2b, and 2c, characters “main food”, “main dish”, and “side dish” are displayed. If lunch is packed into the storage units 2a, 2b and 2c in accordance with the letters “main meal”, “main dish” and “side dish”, the amount of staple food, main dish and side dish will be in a 1: 1 ratio without error. Can be adjusted. The character may be formed or laser engraved. Moreover, not only the said character but the figure replaced with the said character may be sufficient.

  In this way, the first lunch box 1 and the second lunch box 2 have different proportions of staple food, main dish, and side dish of the packed lunch, and different nutritional composition ratios of the packed lunch. Therefore, the first lunch box 1 and the second lunch box 2 are properly used when an obese person diets and when a diabetic patient performs dietary therapy. Hereinafter, the proper use of the first lunch box 1 and the second lunch box 2 will be described. FIG. 3 is a graph illustrating the difference in nutrient composition rate according to the type of lunch box.

  The data shown in the graph is based on the sample obtained by the applicant of the present invention by collecting a sample of 239 meals for the first lunch box 1 and a sample of 144 meals for the second lunch box 2. It is. Moreover, the variable p shows the value which examined whether it is statistically significant, and shows that it is statistically significant when a value is less than 0.05. The variable p indicates that Pearson's product moment correlation coefficient is statistically significant in correlation analysis, and that there is a significant difference in Student's t test.

  The nutrients that make up the lunch box packed in the lunch box are proteins, lipids and carbohydrates. The nutritional composition of the lunch box packed in the first lunch box 1 is relatively low in protein and lipid, and the nutritional composition of the lunch box packed in the second lunch box 2 is well balanced and relative to carbohydrates. (See FIG. 3).

  Therefore, in the calorie content measurement system for a lunch box according to the present invention, when a diet for an obese person who should refrain from taking proteins and lipids, the calorie content is measured using the first lunch box 1, It is preferable to measure the calorie content using the second lunch box 2 when performing dietary therapy for diabetic patients who should take a well-balanced intake while refraining from intake. Thus, in the present invention, by properly using the lunch box, it is possible to accurately check the calorie intake according to the user's situation.

  In addition, the first lunch box 1 and the second lunch box 2 have different volumes (sizes) of the accommodating portions so as to cope with the difference in calorie intake due to differences in the height, weight or labor level of the user. Seven types of lunch boxes are set. Therefore, it will be described whether or not the nutritional composition ratio of the lunch box changes when a lunch box having a different capacity of the storage portion is used. FIG. 4 is a list showing the correlation between the volume of the storage portion and the nutritional composition ratio of the lunch box packed in the lunch box.

  The data shown in the list is based on the sample obtained by the applicant of the present invention taking a sample of 239 meals for the first lunch box 1 and a sample of 144 meals for the second lunch box 2. is there. The variable r is a Pearson product moment correlation coefficient representing the strength of the correlation. The absolute value ranges from 0 to 1, and the larger the absolute value, the stronger the correlation. Moreover, the variable p shows the value which examined whether it was statistically significant, and is a significance probability which shows that it is statistically significant when a value is less than 0.05. The variable p indicates that Pearson's product moment correlation coefficient is statistically significant in correlation analysis, and that there is a significant difference in Student's t test.

  The protein ratio and the lipid ratio variable r of the lunch box packed in the first lunch box 1 are negative numbers, and the first lunch box increases as the volume of the storage portion of the first lunch box 1 increases. It was found that the nutrient composition rate of the protein and lipids in the lunch box packed in the box decreased (see FIG. 4). In addition, since the value of the protein and lipid variable p of the lunch box packed in the first lunch box 1 is 0.05 or less, the nutritional composition of the protein and lipid of the lunch box packed in the first lunch box 1 The change in rate is statistically significant.

  Therefore, when the first lunch box 1 having a different volume of the container is used for a diet of an obese person who should refrain from intake of proteins and lipids, the larger the volume of the first lunch box 1 to be used, the more the protein and It is possible to eat a meal with a low nutritional composition ratio of lipids and to set the calorie intake while maintaining the optimal nutritional composition ratio.

  Moreover, since the value of the carbohydrate ratio, protein ratio, and lipid ratio variable p of the lunch box packed in the second lunch box 2 exceeds 0.05, the volume of the accommodating portion of the second lunch box 2 is increased. It was found that the nutritional composition ratios of the carbohydrates, proteins, and lipids of the lunch box packed in the second lunch box 2 did not change even when it was used (see FIG. 4).

  Therefore, when the second lunch box 2 having a different volume of the accommodating portion is used for the diet therapy of a diabetic patient who should take a well-balanced intake, the calorie content can be set without affecting the nutritional composition ratio. .

  Thus, in the present invention, the volume of the lunch box can be changed so as to be able to cope with the difference in calorie intake due to the difference in the height, weight or labor level of the user, and in accordance with the situation of the user. You can select the type of lunch box and set the calorie intake accurately while maintaining the optimal nutritional composition rate.

  CPU38 controls each hardware with which the calorie content measuring device 3 for lunch is provided. In addition, the CPU 38 executes processing related to the measurement of the calorie content for lunch according to the program read from the auxiliary storage device 33 to the RAM 32. In the measurement of the amount of calories for lunch, the CPU 38 receives the type of the lunch box input via the input unit 35, and controls the weighing unit 34 to measure the weight of the received type of lunch box. The CPU 38 reads the empty weight of the lunch box corresponding to the input type stored in the auxiliary storage device 33, and subtracts the weight of the measured lunch box by the weight of the empty lunch box that has been read. The weight of the lunch box packed in the lunch box is calculated. Further, the CPU 38 calculates the calorie amount of the lunch box based on the calculated lunch box weight, and performs control to output the calculated calorie amount from the monitor 36a or the speaker 37a.

  In addition, the CPU 38 reads the predetermined calorie amount stored in the auxiliary storage device 33, compares the read predetermined calorie amount with the calculated calorie amount, and determines that the compared difference exceeds a predetermined threshold value. Then, control is performed to output the determination result from the monitor 36a or the speaker 37a.

  In the present invention, seven types of lunch boxes with different capacities (sizes) of the accommodating portions are set so as to cope with differences in calorie intake due to differences in the height, weight or labor level of the user. One of the above is the target of measurement. Therefore, a method for calculating the calorie content of the lunch box packed in the lunch box based on the volume of the lunch box will be described. FIG. 6 is a graph showing the correlation between the volume of the lunch box and the calorie content of the lunch box packed in the lunch box. Hereinafter, the variable X indicates the volume of the lunch box, and the variable Y indicates the calorie content of the lunch box. Moreover, the variable p shows the value which examined whether it was statistically significant, and is a significance probability which shows that it is statistically significant when a value is less than 0.05. The variable p indicates that the Pearson product-moment correlation coefficient is statistically significant as a result of testing by correlation analysis. The variable r is a Pearson product moment correlation coefficient representing the strength of the correlation. The absolute value ranges from 0 to 1, and the larger the absolute value, the stronger the correlation.

  The present applicant conducted the following investigation. The calorie content (Y) was measured when the volume (X) of the lunch box was 0 to 1000 (ml). The result of the measurement is as shown by the circles on the graph of FIG. When a regression line was obtained from the average of the illustrated dot group, a relational expression of Y = −70.878 + 0.795X was derived from the regression line i. As a result, it was found that the calorie amount (Y) relative to the volume (X) of the first lunch box 1 can be calculated by regressing Y = −70.878 + 0.795X.

  Note that the regression line i has a variable r of 0.894 and is close to 1, and the volume of the first lunch box 1 and the calorie content are very strongly correlated. The regression line i is statistically significant because the variable p is less than 0.05.

  Similarly, a relational expression of Y = 44.581 + 0.641X was derived from the regression line j. As a result, it was found that the calorie amount (Y) with respect to the volume (X) of the second lunch box 2 can be calculated by regressing Y = 44.581 + 0.641X.

  Note that the regression line j has a variable r of 0.874 and is close to 1, indicating that the volume of the second lunch box 2 and the calorie content are very strongly correlated. The regression line j is statistically significant because the variable p is less than 0.05.

  Similarly, a relational expression of Y = −32.992 + 0.738X was derived from the regression line k. As a result, it was found that the calorie amount (Y) with respect to the entire lunch box volume (X) can be calculated by regressing Y = −32.992 + 0.738X. The ratio of the calorie content (Y) to the volume (X) of all lunch boxes was found to be 0.7 [kcal] per 1 ml of lunch box volume.

  Note that the regression line k has a variable r of 0.884 and is close to 1, and the volume of the lunch box and the calorie content are very strongly correlated. The regression line k is statistically significant because the variable p is less than 0.05.

  Thus, in the present invention, the user is instructed about the calorie intake according to his height, weight or labor level and the volume of the lunch box according to the calorie intake, and the user was instructed. When the lunch box volume is input, the CPU 38 can receive the lunch box volume, substitute the received volume into the above relational expression, and calculate a predetermined calorie amount corresponding to the received volume. The calculated calorie content is compared with the calorie content of the lunch calculated based on the weight of the lunch box described later. Note that data on the above relational expression is stored in advance in the auxiliary storage device 33.

  In the present invention, in the measurement of the lunch calorie content, the CPU 38 calculates the calorie content of the lunch packed in the lunch box based on the weight of the lunch box. Therefore, the correlation between the weight of the lunch box and the calorie content of the lunch box will be described. FIG. 7 is a graph showing the correlation between the weight of the lunch box and the calorie content. Hereinafter, the variable Z indicates the weight of the lunch, and the variable Y indicates the calorie content of the lunch. Moreover, the variable p shows the value which examined whether it was statistically significant, and is a significance probability which shows that it is statistically significant when a value is less than 0.05. The variable p indicates that the Pearson product-moment correlation coefficient is statistically significant as a result of testing by correlation analysis. The variable r is a Pearson product moment correlation coefficient representing the strength of the correlation. The absolute value ranges from 0 to 1, and the larger the absolute value, the stronger the correlation.

  The present applicant conducted the following investigation. The calorie content (Y) was measured when the weight (Z) of the lunch box was 0 to 600 [g]. The measurement results are shown as circles on the graph of FIG. When a regression line was obtained from the average of the illustrated dot group, a relational expression Y = -18.178 + 1.502Z was derived from the regression line l. As a result, it was found that the calorie content (Y) with respect to the weight (Z) of the lunch packed in the first lunch box 1 can be calculated by regressing Y = -18.178 + 1.502Z. It was.

  Note that the regression line l has a variable r of 0.947 and is close to 1, and the weight and calorie amount of the lunch packed in the first lunch box 1 are very strongly correlated. The regression line l is statistically significant because the variable p is less than 0.05.

  Similarly, a relational expression of Y = 44.058 + 1.266Z was derived from the regression line m. As a result, it was found that the calorie amount (Y) relative to the weight (Z) of the second lunch box 2 can be calculated by regressing Y = 44.058 + 1.266Z.

  The regression line m has a variable r of 0.892 and is close to 1, and the weight and calorie amount of the lunch packed in the second lunch box 2 are very strongly correlated. Further, the regression line m is statistically significant because the variable p is less than 0.05.

  Similarly, a relational expression of Y = -2.904 + 1.441Z was derived from the regression line n. As a result, it was found that the calorie amount (Y) with respect to the weight (Z) of all lunch boxes can be calculated by regressing Y = -2.904 + 1.441Z. The ratio of the calorie content (Y) to the weight (Z) of all the lunch boxes was found to be about 1.4 [kcal] per 1 [g] of the lunch box weight.

  Note that the regression line n has a variable r of 0.933 and is close to 1, and the weight of the lunch and the calorie content are very strongly correlated. The regression line n is statistically significant because the variable p is less than 0.05.

  Thus, in the present invention, when the weight of the lunch box is measured by the measuring unit 34, the weight of the lunch box weighed by the CPU 38 is subtracted by the empty weight of the lunch box and packed in the lunch box. By calculating the weight of the lunch box and substituting the calculated weight of the lunch box into the above relational expression, the calorie content (Y) of the lunch box is calculated based on the calculated weight (Z) of the lunch box. Note that data on the above relational expression is stored in the auxiliary storage device 33.

  Furthermore, in the present invention, for example, a predetermined calorie amount corresponding to the volume of the lunch box is compared with the calorie amount calculated based on the weight of the lunch box, and the comparison result is output. Therefore, the significance in the case of prescribing the calorie amount (Y) of the lunch box packed in the lunch box using the volume of the lunch box (X), the weight of the lunch box (Z), the type of lunch box and lipid as factors. To do. FIG. 8 is a list showing the results of multiple regression analysis on the calorie content of the lunch box.

The data shown in the list is based on a sample of 239 meals collected from the first lunch box 1 and a sample of 144 meals collected from the second lunch box 2. The variable β is a regression coefficient of each variable. The absolute value ranges from −1 to 1, and the larger the absolute value, the greater the change in the dependent variable with respect to the change in the explanatory variable. The variable p is a value obtained by examining whether or not the regression coefficient β is statistically significant, and is a significance probability indicating that the regression coefficient β is statistically significant when the value is less than 0.05. The variable R is a multiple correlation coefficient, and R ² is a value indicating the magnitude of the influence of the dependent variable by all statistically significant explanatory factors.

Lunch box weight (Z), lunch box volume (X), lunch box lipid, lunch box type (in order of significance) which defines the calorie content (Y) of the lunch box packed in the lunch box (Figure) 8). When a combination of these factors to obtain a finding that it is possible to define the exact amount of calories (Y) with a probability of 90% 3 min 2 rin (see R ² in FIG. 8). That is, a more accurate calorie amount can be defined by combining the lunch box volume with the lunch box weight.

  Thus, in the present invention, the user calculates the amount of calories ingested according to the difference in his / her height, weight or labor level. A volume corresponding to the calculated calorie intake is calculated, and a lunch box with the calculated volume is selected. Pack the lunch in the selected lunch box. The CPU 38 measures the weight of the lunch box, and calculates the calorie amount of the lunch box packed in the lunch box based on the measured weight of the lunch box. The CPU 38 compares the calorie amount calculated by weight with the initially calculated calorie amount, and outputs the comparison result. By this comparison, an accurate calorie amount (Y) can be defined with a high probability. Further, the user can intuitively confirm whether or not the optimum calorie content can be ingested by viewing the output comparison result.

Example 1.
Next, the procedure of the measurement processing of the calorie content for lunch executed by the CPU 38 of the calorie content measuring device 3 for lunch will be described. FIG. 9 is a flowchart showing the procedure of the measurement process executed by the calorie content measuring device 3 for lunch.

  The user prepares a lunch box with a volume corresponding to the calorie intake corresponding to his / her height, weight, labor level, etc., by lending from a doctor or by purchasing it. The user packs an appropriate amount of staple food, main dish, and side dish lunch in each of the storage units of the lunch box. The user inputs a measurement start request via the input unit 35 of the lunch box calorie measuring device 3.

  The CPU 38 of the lunch box calorie measuring device 3 determines whether or not an input of a measurement start request has been accepted (S101). If it is determined that an input of a measurement start request has not been accepted (NO in S101), the process proceeds to step S101. Return and repeat the process.

  On the other hand, if the CPU 38 determines that the input of the measurement start request has been received by the input unit 35 (YES in S101), the lunch box is placed on the cradle 34a at a predetermined timing and the weight of the lunch box is measured by the weighing unit 34. It is determined whether or not weighing is performed (S102). As a result, when the CPU 38 determines that the weight of the lunch box is not measured by the measuring unit 34 (NO in S102), the measurement process is terminated.

  On the other hand, if the CPU 38 determines that the weight of the lunch box is being measured by the measuring unit 34 (YES in S102), the CPU 38 determines whether the volume of the lunch box has been received by the input unit 35 (S103). When it is determined that the volume of the lunch box is received (YES in S103), the weight of the empty lunch box corresponding to the received volume is read from the auxiliary storage device 33 (S104), and the weight of the lunch box measured by the measuring unit 34 is read. Subtracting the weight of the empty lunch box, the weight of the lunch box packed in the lunch box is calculated (S105).

  The CPU 38 determines whether or not the type of the lunch box has been received by the input unit 35 (S106). If the CPU 38 determines that the type of the lunch box has been received (YES in S106), the data of the relational expression corresponding to the received type is obtained. Reading from the auxiliary storage device 33 (S107), the weight of the lunch is substituted into the read relational data, and the calorie content of the lunch is calculated (S108). The relational expression here corresponds to the relational expression of the regression line l as a relational expression corresponding to the first lunch box 1 and the relational expression of the regression line m as a relational expression corresponding to the second lunch box 2. Applicable (see FIG. 7). The CPU 38 outputs the calculated calorie amount of the bento by displaying it on the monitor 36a or reading it out through the speaker 37a (S109).

  On the other hand, in step S103, if the CPU 38 determines that the volume of the lunch box has not been received (NO in S103), the predetermined weight is read from the auxiliary storage device 33 (S110), and the lunch box measured by the weighing unit 35 is read. The weight is subtracted by the predetermined weight read from the auxiliary storage device 33, and the weight of the lunch box packed with the lunch box is calculated (S105). The predetermined weight here is inputted in advance by the user and stored in the auxiliary storage device 33. Since the procedure after step S106 is the same as the procedure described above, the description thereof is omitted.

  In step S106, if the CPU 38 determines that the type of the lunch box has not been received (NO in S106), it reads data of a predetermined relational expression from the auxiliary storage device 33 (S111), and reads the weight of the lunch box. The calorie content of the lunch box is calculated by substituting it into data of a predetermined relational expression (S108). The predetermined relational expression here corresponds to the relational expression of the regression line n as a relational expression corresponding to all lunch boxes (see FIG. 7).

Example 2
In Example 1 described above, an example has been described in which the lunch calorie amount calculated based on the weight of the lunch box can be confirmed. Therefore, in Example 2, an example in which a more accurate calorie amount can be confirmed by combining the lunch box volume with the lunch box weight will be described. FIG. 10 is a flowchart showing the procedure of the measurement process executed by the lunch box calorie measuring device 3 in another embodiment, and FIG. 11 is a schematic diagram showing a display example of a screen displayed by the lunch box calorie measuring device 3.

  The user prepares a lunch box with a volume corresponding to the calorie intake corresponding to his / her height, weight, labor level, etc., by lending from a doctor or by purchasing it. The user packs an appropriate amount of staple food, main dish, and side dish lunch in each of the storage units of the lunch box. The user inputs a measurement start request via the input unit 35 of the lunch box calorie measuring device 3.

  The CPU 38 of the lunch box calorie measuring device 3 determines whether or not an input of a measurement start request has been accepted (S201). If it is determined that an input of a measurement start request has not been accepted (NO in S201), the process proceeds to step S201. Return and repeat the process.

  On the other hand, when the CPU 38 determines that the measurement start request has been received by the input unit 35 (YES in S201), the lunch box is placed on the receiving base 34a at a predetermined timing, and the weighing unit 34 measures the weight of the lunch box. It is determined whether or not (S202). As a result, if the CPU 38 determines that the weight of the lunch box has not been measured by the measuring unit 34 (NO in S202), the measurement process ends.

  On the other hand, when the CPU 38 determines that the weight of the lunch box is being measured by the measuring unit 34 (YES in S202), the input unit 35 receives the volume of the lunch box (S203), and the empty state corresponding to the received volume. The weight of the lunch box is read out (S204). The CPU 38 subtracts the weight of the lunch box that has been emptied by the metering unit 34 and calculates the weight of the lunch that is packed in the weight of the lunch box (S205).

  The CPU 38 accepts the type of the lunch box at the input unit 35 (S206), and reads the relational expression data corresponding to the accepted type from the auxiliary storage device 33 (S207). The relational expression here is used to calculate the calorie content of the lunch box packed in the lunch box from the volume of the lunch box received in step S203. Specifically, the relational expression of the regression line i corresponds to the relational expression corresponding to the first lunch box 1, and the relational expression of the regression line j corresponds to the relational expression corresponding to the second lunch box 2 (FIG. 6). Moreover, it uses in order to calculate the calorie content of the said lunch from the weight of the lunch calculated at step S205. Specifically, the relational expression of the regression line l corresponds to the relational expression corresponding to the first lunch box 1, and the relational expression of the regression line m corresponds to the relational expression corresponding to the second lunch box 2 (FIG. 7).

  The CPU 38 substitutes the volume of the lunch box into the data of the first relational expression to calculate the calorie amount of the lunch box (hereinafter referred to as “first calorie amount”) (S208). Further, the CPU 38 substitutes the weight of the lunch box for the data of the second relational expression to calculate the calorie amount of the lunch box (hereinafter referred to as “second calorie amount”) (S209). The CPU 38 compares the calculated first calorie amount and the second calorie amount, and calculates the compared difference D, that is, (second calorie amount)-(first calorie amount) (S210). The CPU 38 outputs the calculated result (S211). For example, when the difference D> 0, the CPU 38 displays a notification that the calorie content of the lunch box packed in the lunch box exceeds the calorie content to be ingested on the monitor 36a (see FIG. 11A). . Further, when the difference D <0, the CPU 38 displays a notification that the calorie content of the lunch box packed in the lunch box is smaller than the calorie amount to be ingested on the monitor 36a (see FIG. 11B). Further, when the difference D = 0, the CPU 38 displays a notification that the calorie content of the lunch box packed in the lunch box is the calorie amount to be ingested on the monitor 36a (see FIG. 11C).

  Next, an example of diet therapy using the lunch box calorie content measurement system according to the present invention will be described. For example, when a diabetic patient is instructed to take 1,800 [kcal] calories per day, it is difficult for a diabetic patient who does not have expertise to accurately manage the calorie intake. . Therefore, the diabetic patient is instructed to eat in a lunch box having a volume of 860 [ml]. In addition, a diabetic patient is instructed to use the second lunch box 2 in which the volume of the accommodating portion is 1: 1. In addition, diabetics are instructed in a lunch box with an optimal volume.

  The diabetic patient inputs information indicating the instructed second lunch box to the lunch calorie measuring device 3 as the type of the lunch box. In addition, the diabetic patient inputs the volume of the lunch box instructed by the lunch box calorie measuring device 3. The diabetic patient stuffs the main meal, the main dish, and the side dish into the lunch box housing part, and measures the weight of the lunch box with the lunch box calorie measuring device 3.

  The lunch calorie measuring device 3 calculates the first calorie content based on the volume of the lunch box. Moreover, the calorie content measuring device 3 for lunch calculates the 2nd calorie content based on the weight of the lunch packed in the measured lunch box. The lunch box calorie measuring device 3 calculates the difference between the calculated first and second calorie amounts, and displays the calculated result on the monitor 36a. The diabetic patient adjusts the filling condition of the lunch box while checking whether the calorie amount of the lunch box packed in the lunch box is 860 [kcal] instructed.

  Moreover, when the person who received the instruction is an obese person, the amount of calorie intake according to the diet of the obese person can be obtained by using the first lunch box 1 having a volume of the accommodating part of 3 to 1: 2. Can be confirmed accurately.

  Further, the weight of the empty lunch box is obtained by measuring the empty lunch box by the measuring unit 34 and storing the measured weight in the auxiliary storage device 33. Further, when the volume of the target lunch box is received by the input unit 35 and the empty lunch box is measured by the measuring unit 34, the measured weight and the received volume are stored in association with each other in the table T. . FIG. 12 is a schematic diagram illustrating a storage example of the table T. The table T is generated for each type of lunch box such as the first lunch box 1 and the second lunch box 2, for example. The table T includes fields for storing volume and weight. The volume field stores the volume and material values of the lunch box.
