Description

The present invention relates to a liquid container capable of detecting the amount of liquid flowing out, and a configuration of a flow rate detection unit.

There are various types of liquid containers that store liquid, including beverage containers such as stainless steel bottles, but basically they have a liquid container that stores the liquid and an opening provided at the top of the liquid container. It has a section and a. In such a liquid container, the liquid storage section is tilted horizontally to lower the position of the upper end side opening, thereby allowing the liquid stored in the liquid storage section to flow out.

In particular, for beverage containers such as stainless steel bottles, a stopper body with a drinking spout for direct drinking is removably fitted into the opening at the top end of the bottle body, which is the beverage container that stores the beverage. , has a structure in which a lid is provided on the top (see Patent Document 1). In this case, the drinking spout forms the liquid outlet.

In the case of such liquid containers for beverages, it would be convenient in various respects if the amount of beverage actually consumed (intake amount) could be measured. For example, in the summer when hydration is essential, parents can use the beverage containers given to children and the elderly to determine whether they are actually drinking or not and whether they are drinking enough. By monitoring the measurement data via a predetermined communication system, it is possible to construct a user monitoring service system for homes and facilities (hospitals). However, in the case of a conventional beverage container configuration, such a measuring function is not provided, and such a request cannot be met.

Therefore, we have developed a method for detecting a decrease in the content of a beverage container using a capacitive capacitance sensor in which an electrostatic rod for detecting liquid level is immersed in the beverage container, as described above, and a method for detecting a decrease in the content of a beverage container by using an electrostatic capacitance sensor in which an electrostatic rod for detecting the liquid level is immersed in the beverage container. A conceivable method is to provide a volumetric flow rate sensor having rotating blades such as an oval gear to measure the amount of beverage flowing out from the liquid outlet.

However, when using a capacitive flow sensor, it is necessary to install a long electrostatic rod inside the container as described above, which limits the shape of the container and the structure of the stopper body, and the material of the container body. If the liquid level is made of a conductive material such as metal, there is a problem that the liquid level cannot be detected accurately. In addition, in the case of a positive displacement flow sensor that uses the rotation of a rotary vane, the rotation of the rotary vane is affected by the flow rate and flow rate of the beverage, making accurate flow rate detection not always possible. There are problems such as the outflow resistance making it difficult to drink the drink smoothly, the rotation of the rotary blades tending to cause air bubbles in the drink, and the structure of the narrow liquid outlet becoming complicated and difficult to clean.

Such a problem is not limited to the beverage container described above, and is not limited to the above-mentioned beverage containers. This is a common problem with liquid containers that are lowered to allow the liquid contained in the liquid container to flow out, and a solution is required.

The present invention was made based on such circumstances, and an object of the present invention is to provide a liquid container and a flow rate detection unit that can accurately calculate the amount of liquid flowing out depending on the inclination angle.

The liquid container according to the present invention includes a container body including a liquid storage portion, and a diameter of the container body is smaller than a diameter of an opening of the container body through which the liquid flows out from the liquid storage portion of the container body. a liquid outflow port provided at a position offset from the center toward the front side of the container body ; a liquid outflow detection means for detecting a liquid outflow state at the liquid outflow port ; and a horizontal direction on the front side of the container body. a container inclination angle detection means for detecting an inclination angle relative to the container inclination angle; Liquid outflow amount calculation means for detecting the amount of liquid flowing out to the outside.

The amount of liquid that flows out from the liquid outlet when the container body is horizontally tilted increases as the inclination angle of the container body increases from the time when the liquid starts flowing out, depending on the internal volume at that time.

Therefore, in the present invention, a liquid outflow detection means for detecting the outflow state of the liquid at least at the liquid outflow port of the container body, a container inclination angle detection means for detecting the inclination angle of the container body with respect to the horizontal direction on the front side , and a container inclination liquid outflow amount calculation means for detecting the amount of liquid flowing out of the container body from the inclination angle of the container body detected by the angle detection means and the outflow state of the liquid detected by the liquid outflow detection means; Based on the inclination angle of the container main body detected by the container inclination angle detection means and the detection result of the liquid outflow detection means that detects the outflow of liquid at the liquid outflow port of the container main body, the liquid in the container main body is detected to the outside. It is designed to detect the amount of outflow. In addition, the liquid outlet portion through which the liquid flows out from the liquid storage portion of the container body has a diameter smaller than the diameter of the opening of the container body, and is provided at a position offset from the center of the container body to the front side of the container body. This makes it possible to appropriately detect the amount of outflow even when the amount of liquid in the container body is low.

According to such a configuration, the liquid outflow amount calculation means calculates only the inclination angle of the container body with respect to the front side horizontal direction detected by the inclination angle detection means and the outflow of liquid at the liquid outflow port detected by the liquid outflow detection means. It is now possible to easily calculate the amount of liquid flowing out of the container body, and it is now possible to easily calculate the amount of liquid flowing out from inside the container or liquid flow, such as the electrostatic rod of a conventional capacitive flow sensor or the rotating blade of a positive displacement flow sensor. Parts installed at the outlet are no longer required. Therefore, the above-mentioned conventional problems are reliably solved.

In the above configuration, the liquid outflow amount calculation means calculates the content amount of the liquid in the container body based on the inclination angle with respect to the horizontal direction on the front side of the container body at which the liquid can flow out from the liquid outflow port. The liquid outflow detection means has a liquid content calculation function, and the liquid outflow detection means corresponds to the inclination angle of the container body when the liquid outflow detection means detects the start of liquid outflow. Preferably, the amount of liquid flowing out to the outside is detected based on the difference between the amount of liquid inside the container body and the amount of liquid in the container body corresponding to the inclination angle of the container body when detecting the stoppage of liquid outflow.

According to such a configuration, the liquid content amount corresponding to the inclination angle of the container body at the time when the liquid outflow detection means starts detecting the liquid outflow at the liquid outflow port and the liquid outflow at the liquid outflow port by the liquid outflow detection means. Due to the difference in the amount of liquid that corresponds to the inclination angle of the container body at the time of end detection, the liquid that has flowed out from the container body can be detected without causing problems like conventional capacitive flow sensors or positive displacement flow sensors. The outflow amount can be calculated easily and accurately.

In the above configuration, the calculation of the content amount of the liquid in the container body corresponding to the inclination angle of the container main body when the liquid outflow detection means detects the start of liquid outflow is performed in advance at each predetermined inclination angle of the container body. Preferably, the measurement is performed based on actual measurement data of the internal content of the main body.

In this case, data indicating the relationship between the tilt angle of the container body with respect to the horizontal direction and the corresponding liquid content can be obtained by, for example, actually tilting the container body filled with liquid at a predetermined angle horizontally. It is created by measuring and recording the content inside the container body at every predetermined angle of inclination (for example, 5 degrees). This data is then converted into digital data and stored in a predetermined memory unit (ROM).

The liquid outflow amount calculation means reads out the content amount data stored in the memory section (ROM) using the inclination angle of the container main body detected by the inclination angle detection means as a parameter, and calculates the content amount of the liquid.

By calculating the container content based on actual experimental data in this way, it is possible to calculate the accurate content according to the inclination angle of the container body, and the liquid at the liquid outlet by the liquid outflow detection means can be calculated accurately. The content amount of liquid corresponding to the inclination angle of the container body at the time of start of outflow detection and the content amount of liquid corresponding to the inclination angle of the container body at the time of detecting the end of outflow of liquid at the liquid outflow port by the liquid outflow detection means. The amount of liquid flowing out from the container body calculated from the difference is also accurate.

In the above configuration, the calculation of the content amount of the liquid in the container body corresponding to the inclination angle of the container body when the liquid outflow detection means detects the start of liquid outflow is performed in the liquid storage portion of the container body. This is done based on calculation data obtained by calculating in advance the relationship between the inclination angle with respect to the horizontal direction at which the liquid can flow out from the liquid outlet and the content of the liquid in the container body at that time, corresponding to the form. and is suitable.

The data showing the relationship between the inclination angle of the container body with respect to the horizontal direction according to the shape of the container body and the corresponding liquid content is based on the fact that the container body filled with liquid is actually tilted horizontally at a predetermined angle. Accurately obtained data can be obtained by measuring and recording the content inside the container body at each predetermined angle of inclination as the container body is tilted. It can also be obtained by calculating the content.

In other words, if the shape (e.g., cylindrical shape) and dimensions (radius and length) of the liquid storage part of the container body are known, it is possible to geometrically calculate the change in the volume shape of the liquid content that changes according to the change in the inclination angle of the container body. Accurate content data can be obtained by calculating and computer simulation. This data is then converted into predetermined digital data and stored in a predetermined memory unit (ROM).

The liquid outflow amount calculation means reads out the content amount data stored in the memory section (ROM) using the inclination angle of the container main body detected by the inclination angle detection means as a parameter, and calculates the content amount of the liquid.

With such calculation data, it is possible to accurately calculate the content according to the inclination angle of the container body, and the inclination angle of the container body at the time when the liquid outflow detection means starts detecting the outflow of liquid at the liquid outflow port. The amount of liquid from inside the container body is calculated from the difference between the corresponding amount of liquid and the amount of liquid corresponding to the inclination angle of the container body when the liquid outflow detection means detects the end of liquid outflow at the liquid outflow port. The amount of outflow will also be accurate.

In the above configuration, the liquid outflow port is configured of a light transmitting body that transmits light, and the liquid outflow detection means is configured of a photosensor that includes a light emitting unit and a light receiving unit that face each other with the liquid outflow port in between. It is preferable that the

According to such a configuration, when the container main body is not inclined or the inclination angle is smaller than a predetermined angle and the liquid is not flowing out from the liquid outlet part of the container main body, the containers face each other across the liquid outlet part. A photosensor consisting of a light emitting part and a light receiving part is set to an OFF state, and becomes an ON state when the container body is tilted beyond a predetermined inclination angle and liquid begins to flow out from the liquid outlet of the container body. It is possible to detect the start of liquid outflow at the liquid outflow port by setting this to . In addition, when the tilting operation of the container body stops at a predetermined tilt angle state and liquid no longer flows out from the liquid outlet of the container body, the photo sensor is set to be in the OFF state, and the liquid outlet is It is possible to detect the end of liquid outflow.

In this case, it is preferable that the optical axes of the light emitting section and the light receiving section of the photosensor are provided in a state that is perpendicular to the liquid outlet path of the liquid outlet section, for example. In this way, the detection accuracy and responsiveness of the liquid outflow and the end of the outflow by the photosensor are improved, and the calculation accuracy of the liquid outflow amount is improved.

In the above configuration, the liquid outlet portion is a spout portion of a spout member that is detachably attached to the opening of the container body, and the stopper body includes a lid body that can be opened and closed with respect to the spout member. It is preferable that it is detachably attached.

According to such a configuration, the liquid storage portion is a cylindrical container with an open upper end for storing a beverage, and the liquid outlet portion is a spout portion of a spout member detachably attached to an opening of the container. In a beverage container in which a stopper body having an openable and closable lid body is detachably attached to a drinking spout member, the same liquid outflow amount calculation function as described above and other effects can be obtained.

In the above configuration, it is preferable that a control board is provided inside the stopper body, and the control board is provided with the liquid outflow detection means, the container inclination angle detection means, and the liquid outflow amount calculation means. .

In the case of the above-mentioned beverage containers , the stopper main body generally has a cylindrical structure, and the inside thereof is a sealed space sealed against the drinking spout. Moreover, a certain amount of space is secured. Therefore, the inside of the stopper body is suitable for providing an electrical control board.
Therefore, if a control board is provided using the inside of such a stopper body, and the liquid outflow detection means, container tilt angle detection means, and liquid outflow amount calculation means are provided on the control board, it is possible to install a special control board. Sealing performance can also be ensured without providing any space.

Therefore, if a control board is provided using the inside of the stopper body, and the liquid outflow detection means, container tilt angle detection means, and liquid outflow amount calculation means are provided on the control board, a special control board installation space is required. Sealing performance can also be ensured without any problems.

In the above configuration, it is preferable that the stopper body including the lid body and the control board be configured as a versatile flow rate detection unit that can be attached to various types of container bodies.

According to such a configuration, the stopper body including the lid body and the control board can be used as an independent flow rate detection unit having a predetermined control function, and can be commonly applied to various container bodies that are not exclusive products. As a result, the stopper body can be used as a platform for the container body, and the stopper body can have its own commercial value independent of the container body.

In the above configuration, the control board includes a predetermined measurement sensor for measuring diagnostic data for diagnosing the user's physical condition, and a communication device capable of receiving a predetermined cloud service from a cloud service provider via a computer network. It is preferable that a control unit with a function is provided, diagnostic data measured by a predetermined measurement sensor is transmitted to a predetermined medical institution via the control unit, and the user's physical condition can be diagnosed. .

In this case, an example of diagnostic data for diagnosing the user's physical condition is, for example, body temperature, and the measurement sensor is configured by a body temperature measurement sensor for measuring body temperature. In that case, a temperature/humidity sensor is also installed to measure the outside temperature and humidity if necessary, and the body temperature measurement data from the body temperature sensor, along with the outside temperature and humidity at that time, is sent to the parent's smartphone or designated hospital, etc. is sent to the PC of the medical institution.

This allows parents and designated medical institutions such as hospitals to diagnose conditions such as heatstroke in users during hot summer days, and to notify users when they need to drink sufficient fluids immediately. instructions to consume the beverage using a smartphone, etc. This makes it possible to provide a monitoring function for children and elderly people when they are out.

Further, the flow rate detection unit according to the present invention has a diameter smaller than a diameter of an opening of the container body from which the liquid flows out from the liquid storage portion of the container body provided with the liquid storage portion, and the flow rate detection unit has a liquid outflow detection means for detecting a state of liquid outflow at a liquid outflow port provided at a position offset toward the front side of the container body ; and a container inclination angle for detecting an inclination angle of the container body with respect to a horizontal direction on the front side. Detecting an amount of liquid flowing out of the container body from a detection means, an inclination angle of the container body detected by the container inclination angle detection means, and a liquid outflow state detected by the liquid outflow detection means. and liquid outflow amount calculation means.

According to the present invention, the flow rate detection unit can be applied to container bodies of various shapes, and the above-mentioned effects can be similarly obtained with a liquid container to which the flow rate detection unit is attached.

As a result of the above, according to the present invention, it is possible to provide a liquid container having a function of calculating the amount of liquid flowing from the inside of the container body to the outside of the container body without causing the problems of the conventional liquid container. For example, if the liquid container is configured as a beverage container, the beverage container can be provided with a beverage intake calculation function, and the stopper body having the beverage intake calculation function can be used universally for various container bodies. It is possible to create a platform as a multi-functional flow rate detection unit that can be applied to

EMBODIMENT OF THE INVENTION Hereinafter, embodiment which is an example of this invention will be described in detail with reference to drawings.
<About the configuration of the liquid container equipped with a liquid outflow amount calculation function according to the first embodiment of the present invention>
1 to 23 show the structure of a liquid container equipped with a liquid outflow amount calculation function according to a first embodiment of the present invention, in which the liquid container of the present invention is configured as a beverage container.

(Construction of the entire beverage container and each part)
First, FIGS. 1 to 13 show the entire structure and each part of a liquid container configured as a beverage container. In this embodiment, an example of a liquid container is a beverage container typified by a stainless steel bottle. Therefore, in the following description, the liquid container will be referred to as a beverage container.

As shown in FIGS. 1, 2, 4, 6, and 11, the beverage container of this embodiment includes a container body 1 having a liquid storage portion S, and a container body 1 that is detachably attached to the container body 1. A plug body 2 is provided.

The container body 1 includes a bottomed cylindrical container 11 and a spout member 12 that is detachably attached to an opening at the top of the container 11. The stopper body 2 is provided on the outer periphery of the drinking spout member 12. The stopper body 2 includes a lid body 3 located above the stopper main body 2 and capable of opening and closing a drinking spout portion 12a at the upper end of the drinking spout member 12.

(About the structure of the container body 1)
The container body 1 is made of a bottomed cylindrical metal member. The side wall portion of the container body 1 is formed into a cylindrical body with the same diameter from the bottom outer circumferential side to the upper outer circumferential side. The center of the bottom wall portion 11b of the container body 1 is raised on a spherical surface by a predetermined height. The upper part of the container body 1 has a circular opening on almost the entire surface. The opening edge 11a of the container body 1 (a predetermined vertical width portion of the upper opening of the container body 1) is reduced in diameter to a slightly smaller diameter. To explain further, a threaded groove for screwing the spout member 12 is formed on the outer circumferential surface side of the opening edge 11a by the thickness of the mounting portion 12b of the spout member 12. The spout member 12 is integrally molded from synthetic resin with a lower large-diameter cylindrical attachment portion 12b screwed onto the outer circumferential side of the opening edge 11a and a small-diameter cylindrical spout 12a that contacts the user's mouth. It consists of items.

The synthetic resin used for the spout member 12 is molded using, for example, an acrylic material (transparent material) with high light transmittance. As will be described later, in order for the infrared light from the light emitting diode 52a provided on both sides of the spout 12a to pass through the spout 12a and directly enter the light receiving surface of the photodiode 52b, which is the light receiving section. It is.

The vertical dimension of the attachment portion 12b corresponds to the vertical dimension of the opening edge 11a. A threaded groove is formed on the inner circumferential surface side of the attachment portion 12b to be threaded into a threaded groove formed on the outer circumferential surface of the opening edge 11a. The inner and outer diameters of the drinking spout 12a are formed to be small enough to be suitable for drinking by placing the tip a little into the mouth. The vertical dimension (length) of the drinking spout 12a is formed to be considerably long. A fitting for fitting an annular sealing member 12c for sealing between the insertion hole 20 formed in the upper wall portion 21 of the stopper main body 2 is provided around the entire circumference of the upper and lower intermediate portions of the spout portion 12a. A groove is provided. The upper end opening surface of the spout 12a has a higher height at the end (front end) in the beverage supply direction, and an opposite end (rear end) located on the opposite side to the end in the beverage supply direction. It is a sloped surface with a low height.

For example, as is clear from FIGS. 7 and 8, the center O2-O2 of the drinking spout 12a is located on the front end side ( It is provided offset to the front side of the beverage container. As a result, even when the amount of beverage in the container body 1 is low, by tilting the container body 1 at an angle greater than horizontal, the beverage (liquid) stored in the liquid storage section S can be almost reliably drunk. I try to do that.

(About the structure of the stopper body 2)

In addition, in the stopper body 2,
The side wall portion 22 extends from the outer peripheral portion of the upper wall portion 21 in a skirt shape (gently arcuate shape) and extends downward for a predetermined length. The lower end side opening of the side wall portion 22 is fitted and fixed to the shoulder portion (having a slightly smaller diameter) of the attachment portion 12b of the drinking spout member 12. The lock lever installation part 23 is located on the front part (front part) of the side wall part 22. The lock lever installation part 23 forms the installation part of the lock lever 7 which is a lid opening/closing operation part. The battery storage case 53 extends backward by a predetermined distance from the rear surface of the side wall portion 22 and then extends downward at right angles.

On the back side of the top wall part 21 and inside the side wall part 22, a control board (electronic board) 5 is mounted on which electronic parts such as various sensors, a control unit, and a transmitting/receiving unit are mounted to realize a calculation function of the amount of beverage flowing out. An installation space for installation has been formed.

A hinge shaft holder 21a having a predetermined length and pivotally supporting a hinge shaft 24 is provided at the rear end of the upper wall portion 21 of the stopper body 2.

Thereby, the lid body 3 is pivotally supported so as to be rotatable in an arc in the vertical direction. A coiled hinge spring (not shown) is wound around the hinge shaft 24 . The hinge shaft 24 has one end engaged with the stopper body 2 and the other end engaged with the lid 3 so as to have elasticity in the repulsion direction (lid opening direction). The hinge shaft 24 rotates and biases the lid 3 from the lock lever 7 side to the rearwardly inclined open state (the state shown in FIGS. 2, 3, and 6) toward the hinge shaft holder 21a. The upper wall portion 21 of the plug body 2 includes two fitting holes 21c and 21d for fixing a control board 5, which will be described later, a temperature and humidity introduction hole 21e corresponding to a temperature and humidity sensor 51e on the control board 5 side, which will be described later. A magnetic force line transmission hole 21b and the like corresponding to a lid opening/closing sensor 51a (Hall sensor) on the control board 5 side, which will be described later, are provided. The temperature/humidity introduction hole 21e and the magnetic force line transmission hole 21b are each provided with a vapor permeable membrane that allows steam to pass through but not water, and is configured to prevent water from entering from the drinking spout 12a side.

The lock lever installation portion 23 includes a U-shaped wall 23a, a recessed groove portion 23b, an upper wall 23c, a circular groove 23d, a convex portion 23e, and a lock lever engagement shaft 8 (see FIGS. 3 to 5). The U-shaped wall 23a is integrally provided with a portion of the side wall portion 22 on the front side projecting in a U-shape. The U-shaped wall 23a is open on the upper end side and the front side. The groove portion 23b is formed within the U-shaped wall 23a and has a U-shaped shape. The upper wall 23c is located at the upper end side opening of the groove portion 23b. The upper wall 23c has a part of the front end of the upper wall portion 21 protruding by a predetermined width and a predetermined length, and serves as a stopper portion for locking the lid of the lock lever 7, whose tip portion will be described later, and a lid portion whose shape portion will be described later. This serves as a fixed surface for the body 3 (side wall portion 32 on the front side of the lid body 3) when the lid is closed. The circular groove 23d is provided slightly below the vertically intermediate portion of the concave groove portion 23b. The lock spring 25 is fitted into the circular groove 23d. The convex portion 23e is provided to protrude from the lower side of the circular groove 23d. The convex portion 23e is used for fixing the lock lever fixing member 6. The lock lever engagement shaft 8 is located between the upper wall 23c and the convex portion 23e, and is installed between the left and right side wall portions of the U-shaped wall 23a.

The lock lever 7 is composed of a lever member made of synthetic resin. An engagement piece 71a that engages with an engagement piece 32b of a lock lever on the lid 3 side, which will be described later, is provided on the upper end 71 side of the lock lever 7. A protrusion 72a for fitting the lock spring 25 is provided on the lower end 72 side of the lock lever 7. A boss portion 73 a having a semicircular cross section and having an engagement groove for engaging the lock lever engaging shaft 8 having a U-shaped cross section is provided in the vertically intermediate portion 73 of the lock lever 7 .

The U-shaped engagement groove of the boss portion 73a of the intermediate portion 73 engages with the lock lever engagement shaft 8 within the concave groove portion 23b and is rotatably supported. The lock spring 25 is provided between the convex portion 72a for fitting the lock spring 25 on the lower end portion 72 side and the circular groove 23d for fitting the lock spring 25 on the concave groove portion 23b side. The lock spring 25 biases the engagement piece 71a of the upper end portion 71 in the direction of engagement with the engagement piece 32b of the lid 3 side.

In this way, when the lock lever 7 is installed in the U-shaped groove 23b in the U-shaped wall 23a, it is attached to the opening edge of the U-shaped groove 23b in the U-shaped wall 23a. The lock lever fixing member 6 is slidably engaged. Thereby, as shown in FIGS. 1, 4, and 5, the lock lever 7 is maintained in a stable engaged state (lid locked state).

The upper end 61 side of the lock lever fixing member 6 is formed into a pressing surface portion that maintains the engagement state of the engaging piece 71a on the upper end 71 side of the lock lever 7 with the engaging piece 32b on the lid body 3 side. . At an upper position on the lower end 62 side of the lock lever fixing member 6, there is a convex portion 62a for a pressing operation to release the engagement state between the engagement piece 71a on the upper end 71 side and the engagement piece 32b on the lid body 3 side. is provided. A claw portion 61a for sliding operation upward or downward is provided at the lower portion of the upper end portion 61 side of the lock lever fixing member 6. An abutment piece 62b is provided at the lower end position of the lock lever fixing member 6 on the lower end portion 62 side. When the lock lever 7 is in the locked state, the abutting piece 62b abuts against the protrusion 23e that fixes the lock lever fixing member 6 in the U-shaped groove 23b, so that even if the protrusion 62a for pressing operation is pressed, the upper end will not move. The engagement state between the engagement piece 71a on the side of the portion 71 and the engagement piece 32b on the lid body 3 side cannot be released.

The lock lever 7 is installed as shown in FIG. 5 with respect to the U-shaped recessed groove 23b in the U-shaped wall 23a where the lock lever 7 is installed. In the U-shaped groove portion 23b, an empty space b having a predetermined length in the vertical direction is provided below the abutment piece 62b. The lock lever fixing member 6 slides in the vertical direction using the empty space b, and the lock lever fixing member 6 slides to the upper end position. In the state shown in FIG. 3 in which the upper end 71 of the lock lever 7 is pressed, the abutting piece 62b on the lower end 72 side abuts against the protrusion 23e that fixes the lock lever fixing member 6, thereby fixing the lock lever 7. The state is maintained.

On the other hand, when the lock lever fixing member 6 is slid downward from the state shown in FIG. The collision with the convex portion 23e that fixes the member 6 is released, and the upper end portion 71 of the lock lever 7 can be rotated. In this state, when the convex portion 62a, which is the pressing operation portion of the lower end portion 72 of the lock lever fixing member 6, is pushed rearward, the lower end portion 72 of the lock lever 7 is pushed backward against the biasing force of the lock spring 25. , the engagement piece 71a on the upper end 71 side of the lock lever 7 rotates forward and disengages from the engagement piece 32b on the lid body 3 side, allowing the lid body 3 to be opened.

The battery storage case 53 has a base portion 53a that has a wiring hole with a bush inside and extends a predetermined length backward from the rear end of the side wall portion 22 of the plug body 2, and a base portion 53a that is bent downward at right angles from the rear end of the base portion 53a. , and a cylindrical battery storage portion 53b extending to an intermediate position in the vertical direction of the container 11. A battery holder 53c having a predetermined width in the horizontal direction and a predetermined length in the vertical direction is installed inside the battery storage section 53b. In the battery holder 53c, dry batteries 57, 57 (for example, two batteries) of a predetermined capacity are arranged side by side in a removable state with their positive and negative polarities reversed. The power supply lead wire 56 extends from the positive terminal of the battery holder 53c toward the control board 5 side. A removable cap member 54 is provided at the lower end of the battery storage portion 53b, and when the cap member 54 is removed, the dry batteries 57, 57 can be replaced. As shown in FIGS. 4 and 6, for example, the battery storage case 53 is integrally molded from synthetic resin as a part of the rear end side of the plug body 2.

A circular space on the inside of the stopper body 2 and on the back side of the upper wall portion 21 is used for an outflow amount calculation device that calculates the amount of beverage in the container 11 that flows out from the spout 12a (amount taken by the user), and for internet communication. This is an installation space for a circular control board 5 that constitutes the electronic circuit of the device.

The control board 5 is provided with various sensors, a control unit, a transmitting/receiving unit, and other electronic components. The control board 5 also has a spout insertion hole 50 coaxially with the insertion hole 20 of the upper wall portion 21 of the stopper body 2 and having approximately the same diameter. When the control board 5 is installed inside the stopper main body 2, the spout 12a is similarly inserted from below to above. The insertion hole 20 of the plug body 2 is sealed with the sealing member 12c, but the insertion hole 50 of the control board 5 is not sealed.

(About the configuration of the control board 5)
As shown in FIGS. 11 to 13, for example, the control board 5 is equipped with a lid opening/closing sensor 51a (Hall sensor), a light emitting diode 51c and a photodiode 51d for face detection, and a temperature/humidity sensor using both the front and back surfaces thereof. 51e, a body temperature sensor 51f, a light emitting diode 52a and a photodiode 52b for detecting the passage of a beverage, a tilt angle sensor 51b (acceleration sensor) serving as a container tilt angle detection means, a transmitting/receiving unit 51h, a transmitting/receiving antenna 55, and an Internet communication control function. Various sensor parts, control parts, and communication parts such as a control unit 51g are provided.

The lid opening/closing sensor 51a, the light emitting diode 51c and photodiode 51d for face detection, the temperature/humidity sensor 51e, the body temperature sensor 51f, and the control unit 51g are provided on the front side of the control board 5. The transmitting/receiving unit 51h and the transmitting/receiving antenna 55 are provided on the back side of the control board 5.

The lid opening/closing sensor 51a detects whether the lid 3 is opened or closed. The lid opening/closing sensor 51a is made of, for example, a Hall sensor. The lid opening/closing sensor 51a detects opening/closing of the lid 3 according to magnetism (proximity of the lid 3) from the magnet 15 provided at a corresponding position on the lid 3.

The light emitting diode 51c and photodiode 51d for face detection detect that the user's face approaches the drinking spout 12a in a state where the lid opening/closing sensor 51a detects that the lid 3 is opened. The light emitting diode 51c and photodiode 51d for face approach detection detect the approach of the user's face when the user opens the lid 3, puts his or her mouth on the drinking spout 12a of the container body 1, and starts drinking. It constitutes a photo sensor. The photodiode 51d detects an increase in the amount of light (infrared light) reflected from the light emitting diode 51c caused by the approach of the user's face, thereby detecting the approach of the user's face by a predetermined distance or more.

When the user's face approaches the light emitting diode 51c and the photodiode 51d by a predetermined distance or more, the photosensor is turned on. In this case, the light emitting diode 51c and the photodiode 51d are located behind the insertion hole 50 of the drinking spout on the front surface side of the control board 5 and are installed to face each other in the left and right direction. The optical axis of the light emitting diode 51c, which is emitted upward through the attachment part 12b of the member 12, is set toward the upper end of the spout part 12a while being inclined at a predetermined angle toward the light receiving axis of the photodiode 51d. Infrared light that hits the face of the user who is about to put his or her mouth on the spout 12a is effectively incident on the photodiode 51d, and the amount of incident infrared light reaches a predetermined level or higher. The photo sensor turns on when This approach of the user's face to a predetermined distance or less is accompanied by the operation to start drinking the beverage following the opening operation of the lid body 3, but in terms of control conditions, it is not detected itself and will be described later. It has a meaning as a criterion for capturing the effective measurement output (body temperature data) of the body temperature sensor 51f. In this case, the light emitting diode 51c is an infrared light emitting diode that is not affected by ambient light.

The temperature and humidity sensor 51e detects the temperature and humidity of the outside air outside the beverage container. The temperature/humidity sensor 51e introduces the outside air from outside the beverage container through the outside air introduction hole 21f (see FIG. 11) provided in the upper wall portion 21 of the stopper body 2, and detects the temperature and humidity (heat and humidity) of the outside air. do. The temperature and humidity of the outside air (heat and humidity) detected here is used as diagnostic data for determining the necessity of preventing heatstroke in the user during the summer, for example. The outside air introduction hole 21f provided in the upper wall portion 21 of the plug body 2 is provided with a resin porous membrane that allows air to pass through but does not allow water to pass through, thereby maintaining the sealing function to the control board 5 side. ing.

The body temperature sensor 51f detects the temperature of the user's face surface (the user's face temperature) in a state where the light emitting diode 51c and photodiode 51d for detecting face proximity detect that the user's face has approached the drinking spout 12a by a predetermined distance or more. body temperature). The body temperature sensor 51f is made of, for example, a thermopile that is a combination of a plurality of thermocouples. The body temperature sensor 51f detects the user's body temperature according to the radiation temperature (absorption temperature) from the user's face surface. The body temperature detected here is also used as diagnostic data for the monitoring system to determine the risk of the user suffering from heat stroke. A body temperature sensor 51f (thermopile) provided on the front side of the control board 5 projects onto the upper wall portion 21 of the plug body 2 through a fitting hole 21c formed in the upper wall portion 21 of the plug main body 2, It is designed to directly absorb the radiant temperature from the user's facial surface. The body temperature detection data detected by this body temperature sensor 51f is taken into the control unit 51g, which will be described later, on the condition that the user's face approaches the spout 12a by a predetermined distance or more, and It is used as diagnostic data to diagnose physical condition.

The light emitting diode 52a and photodiode 52b for detecting the passage of beverage detect that the container body 1 is tilted by a predetermined angle or more and that the beverage has passed through the drinking spout 12a. A light emitting diode 52a and a photodiode 52b for detecting the passage of a beverage detect whether the beverage has passed through the cylindrical spout 12a of the spout member 12 made of a transparent material, that is, whether the user has started drinking the beverage. It constitutes a photosensor that detects whether A light emitting diode 52a and a photodiode 52b for detecting passage of beverage are arranged diametrically front and rear across the spout 12a (base) of the spout 12a. When a beverage passes through the cylindrical spout 12a, the amount of light that enters the photodiode 52b from the light emitting diode 52a is blocked by the beverage to a predetermined amount or less, and the amount of light received by the photodiode 52b decreases. The output of the photodiode 52b also decreases below a predetermined level. Thereby, passage of the beverage (intake of the beverage by the user) is detected.

In this case, more specifically, in a state where the container body 1 is not inclined or a state where the inclination angle is smaller than a predetermined angle and the beverage does not flow out from the drinking spout 12a of the container body 1, the drinking spout 12a A photosensor consisting of a light emitting diode 52a and a photodiode 52b facing each other is set to the OFF state, and the container body 1 is tilted to a predetermined tilt angle or more, and the beverage flows out from the drinking spout 12a of the container body 1. Set it so that it turns on when it starts to do so.

On the other hand, the device is set to be in the OFF state when the tilting operation (ingestion of beverage) of the container body 1 stops at a predetermined tilt angle and the beverage no longer flows out from the drinking spout 12a. In this way, when the photosensor consisting of the light emitting diode 52a and the photodiode 52b is turned on, the start of the outflow (ingestion) of the beverage at the spout 12a is detected, and when the photosensor is turned off, the outflow (intake) of the beverage at the spout 12a is detected. The end of intake (ingestion) can be detected with good responsiveness. In this case, the optical axes of the light emitting diode 52a and the photodiode 52b constituting the photosensor may be provided in a state perpendicular to the central axis (O2-O2 in FIG. 7) of the liquid outflow path of the drinking spout 12a. preferable. By doing so, the detection accuracy and responsiveness of the outflow and end of the outflow of the beverage by the photo sensor are improved, and the calculation accuracy of the amount of beverage intake is improved. In this case as well, an infrared light emitting diode that is not affected by ambient light is used as the light emitting diode 52a.

The tilt angle sensor 51b detects the tilt angle of the container body 1 when the user tilts the container body 1 and ingests the beverage through the drinking spout 12a. The inclination angle sensor 51b employs, for example, a 3-axis acceleration sensor, and measures the inclination angle of the container body 1 with good responsiveness when the user inclines the container body 1 and ingests the beverage through the drinking spout 12a. , detect with high precision.

(About the configuration of the control unit and the control circuit centered on the control unit)
The control unit 51g has a beverage intake calculation function that calculates the amount of beverage ingested by the user (the amount of beverage that has flowed out of the container body 1) based on the inclination angle of the container body 1 detected by the inclination angle sensor 51b; It also has an Internet communication control function via the transmitting/receiving unit 51h.

For example, as shown in FIG. 14, the control unit 51g drives and controls a light emitting diode 51c of a photosensor for detecting face proximity and a light emitting diode 52a of a photosensor for detecting beverage spillage, and also detects the opening/closing of the lid from the lid opening/closing sensor 51a. signal, inclination angle detection data of the container body 1 from the inclination angle sensor 51b, face approach detection signal from the photodiode 51d of the face approach detection photosensor, temperature and humidity detection data from the temperature and humidity sensor 51e, and temperature and humidity detection data from the body temperature sensor 51f. By inputting the body temperature detection data, the beverage outflow detection signal from the photodiode 52b of the photosensor for detecting beverage outflow, and the inclination angle detection data of the container body 1 from the inclination angle sensor 51b, the container body when the user ingests the beverage is detected. The intake amount (outflow amount) of the beverage in the container 11 is calculated based on the inclination angle of 1, and the change in the remaining amount of the beverage in the container body 1 is stored as necessary.

In addition, the temperature and humidity of the outside air (heat and humidity) detected by the temperature and humidity sensor 51e is processed as data for diagnosing the necessity of preventing heatstroke in the summer, for example, and is processed using a computer network such as the Internet or a cloud service. The information is then sent to the parents' smartphones and the attending physician's PC at the hospital (medical institution) they are affiliated with. The user's body temperature data detected by the body temperature sensor 51f is also processed as diagnostic data to specifically determine the user's risk of heat stroke, and is also sent to the parent's smartphone or the affiliated hospital via the computer network cloud. (Clinical institution)'s attending physician's PC.

The control unit 51g inputs the tilt angle detection data of the container body 1 detected by the tilt angle sensor 51b, and controls the outflow of the beverage in the container 11 based on the tilt angle of the container body 1 when the user ingests the beverage. In addition to detecting the amount and managing changes in the remaining amount of beverage in the container body 1, the system also monitors changes in the remaining amount (beverage intake) based on the outside temperature, humidity, and user's body temperature. If it is determined that the outside temperature, humidity, or user's body temperature is high, and it is necessary to actively consume the beverage from the perspective of avoiding heat stroke, the computer network cloud will be used. The system sends instructions to the user's smartphone from the parent's smartphone or the PC of the attending physician at the family hospital (medical institution) to actively consume the beverage, thereby avoiding heatstroke. Users themselves can of course check the outside temperature and humidity as well as the user's body temperature, which are sent via the computer network cloud to the parents' smartphones and the attending physician's PC at the affiliated hospital (medical institution). It is also possible to transmit using existing communication facilities and communication services other than computer networks and clouds.

The communication function using the computer network cloud is performed using the transmitting/receiving unit 51h. A part of the OS functions of the smartphone is installed in this transmitting/receiving unit 51h, and unique application software that can be upgraded can also be installed as desired. Heatstroke prevention and avoidance functions are implemented using these application software.

The transmitting/receiving unit 51h is capable of communicating with the outside and has a function of connecting to the Internet line. The transmitting/receiving antenna 55 is attached to the transmitting/receiving unit 51h. As the transmitting/receiving antenna 55 attached to the transmitting/receiving unit 51h, for example, as shown in FIG. 13 (back view of the control board 5), a planar antenna often used in recent mobile phones is used. The transmitting/receiving unit 51h is connected to the transmitting/receiving unit 51h via a coaxial feeder line 55b. A screw hole 55a is provided in a part of the transmitting/receiving antenna 55 having a planar structure. The transmitter/receiver unit 51h is fixed to the control board 5 by screwing screws from below upward through the screw holes 55a (in the states shown in FIGS. 13, 4, 6, and 10, all are the same). screws are not visible).
(About the installation structure of the control board 5)

It is supported and fixed on the boss parts 13, 13 (the other one is hidden behind the spout part 12a and cannot be seen in FIG. 11).

The upper wall portion 21 of the plug body 2 is provided with two fitting holes 21c and 21d, and the control board 5 is also provided with two screw holes 51i and 51j. These two sets of insertion holes 21c, 21d, 51i, and 51j are screw holes of two boss parts 13 and 13 of a predetermined height provided on the upper surface side of the attachment part 12b of the spout member 12, respectively. It is compatible with coax.

Therefore, the control board 5 is housed inside and above the stopper body 2, and is coaxially supported on the two bosses 13, 13 on the mounting part 12b side of the spout member 12, while the control board 5 is placed on the upper wall of the stopper main body 2. It can be easily fixed by screwing together a screw of a predetermined length from the 21 side. As a result, they are installed as shown in FIGS. 4, 6, and 10.

(About the structure of the lid body 3)
Next, the lid body 3 is constituted by a cylindrical cover member made of synthetic resin and having a high front shape and covering the stopper body 2 and the spout member 12. A rubber seal is provided at a portion of the top wall 31 of the lid body 3 that comes into contact with the spout 12a (its opening) of the spout member 12 in the closed state to seal the spout 12a (its opening). A packing 4 is provided. The lower end portion 32a of the side wall portion 32 on the front side of the lid body 3 has an inverted U shape corresponding to the U-shaped wall 23a for forming a U-shaped lock lever installation portion provided on the front side of the side wall portion 22 of the stopper body 2. It is formed into a U-shaped wall. An engaging piece 32b is provided on the lower surface side of the lid 3, and is engaged with an engaging piece 71a of the lock lever 7 on the stopper body 2 side to lock the lid 3 in the closed state.

The lower end portion 32a, which is an inverted U-shaped wall of the side wall portion 32 on the front side, is connected to the lock lever on the stopper body 2 side, as shown in FIGS. 1, 5, and 9, when the lid body 3 is closed. It continues so as to form the upper end of the U-shaped wall 23a for forming the installation portion, and forms the slide groove for the lock lever fixing member 6 described above.

The left and right pair of hinge brackets 32c, 32c are arranged coaxially on both sides of the hinge shaft holder 21a of the plug body 2, and are mutually connected by inserting the hinge shaft 24 held by the hinge shaft holder 21a of the plug main body 2. The lid body 3 is attached to the stopper body 2 in a state that it can be opened and closed in the vertical direction. In the closed state of FIGS. 4 and 5, the lid 3 is fixed by engaging the engaging piece 32b on the tip side with the engaging piece 71a of the lock lever 7 on the stopper body 2 side. At the same time, the lid body 3 brings the seal packing 4 into contact with the spout portion 12a of the spout member 12 to seal it. The seal packing 4 of the lid 3 includes a medium-high packing piece 42 that seals the spout 12a of the spout member 12, and a packing body 41 that is fitted and fixed into the packing fitting hole 31a of the top wall 31 of the lid 3. It is equipped with
(Characteristics of the structure of the beverage container in this embodiment)
The above beverage container is roughly divided into two parts: a container body 1 shown in FIGS. 7 and 8, and a stopper body 2 shown in FIGS. 9 and 10. By removably fitting the stopper body 2 of the stopper body 2 equipped with the control board 5 to the container main body 1, a drink container having the above-mentioned drink intake calculation function and user monitoring function is constructed. be done.

Therefore, the stopper main body 2 equipped with the control board 5 can be used in desired combination with container main bodies 1 having different capacities and shapes as a general-purpose unit product that determines the product function of the beverage container. The control function of the control board 5 can be adapted to various uses depending on what kind of program is installed in the control unit 51g.

That is, with the same configuration, the stopper body 2 can be configured as a platform member having an independent product function and an exchange value by itself with respect to the container body 1. When configured in this way, the container body 1 can be used for various forms, such as the container body of a beverage container of a different model made by the company, the container body of a beverage container made by another company, or a commercially available PET bottle. become able to.

Further, various sensors and control functions on the control board 5 can be freely upgraded according to the purpose, and functions can be easily changed according to the purpose.
(About the calculation method of beverage intake by the control unit)
By the way, the control unit 51g is provided with, as its basic control function, a beverage intake amount calculation function that calculates the amount of beverage consumed by the user as described above. The calculation method will be described in detail below with reference to FIGS. 16(a) to 16(e).

That is, when a user ingests a beverage from the beverage container configured as described above, the intake forms (drinking forms) shown in FIGS. 16(a) to (c), (d), and (e) are taken, for example. 16(a) to (c), (d), and (e) show only the container body 1 (configuration in FIG. 7) of the above-mentioned beverage container (cross-sectional configuration in FIG. 4). The structure is simplified and a simple model structure is adopted in which the container 11 of the container body 1 and the spout part 12a of the spout member 12 are integrated. Therefore, the length of the spout 12a is also made shorter than the configuration shown in FIG. 7, and the light emitting diodes 52a and photodiodes 52b (photosensors) on both sides of the spout 12a for detecting beverage outflow are also omitted.

In the case of the beverage intake example shown in FIG. 16, a predetermined amount of beverage W is initially stored in the liquid storage portion S in the container body 1 in the container 11 of the container body 1, as shown in FIG. 16(a). In the non-ingestion state, the container main body 1 stands vertically (assuming it is placed on a desk or the like), and its inclination angle θ with respect to the horizontal direction is θ=0 degrees.

Next, as shown in FIG. 16(b), when the container body 1 is tilted horizontally from the vertical state to the inclination angle θ1 (for example, θ1=60 degrees), the detection portion of the drinking spout 12a (for detecting beverage outflow) The upper surface of the beverage W reaches the optical axis portion of the photosensor consisting of the light emitting diode 52a and the photodiode 52b), and begins to flow out from the drinking spout 12a. When the upper surface of the beverage W reaches the detection portion of the drinking spout 12a in this manner, the photosensor consisting of the light emitting diode 52a and the photodiode 52b for detecting beverage outflow is turned from OFF to ON, and the intake of the beverage W is started (start of outflow). ) is detected. At the same time, the content V1 of the beverage W in the container body 1 at the time when the start of beverage intake is detected is calculated. This calculation data of the internal capacity V1 is temporarily stored in the RAM memory of the control unit 51g.

From this state, the user continues to drink the beverage, and eventually the inclination angle θ of the container body 1 increases from θ1 to θ2 (θ2 = 75 degrees), as shown in FIG. 16(c), and the inclination angle θ2 ( If the user stops drinking the beverage at the point when θ2=75 degrees), the inclination angle θ of the container body 1 will no longer increase, and the beverage W will no longer flow out at the detection position of the spout 12a. When the drink runs out, a photosensor consisting of a light emitting diode 52a and a photodiode 52b for detecting drink outflow is turned off, and the end of drink intake is detected. At the same time, the content amount V2 of the beverage in the container 11 at the time when the end of beverage intake is detected is calculated. The calculation data of this internal capacity V2 is also temporarily stored in the RAM memory of the control unit 51g.

In this way, when the calculation of the content volume V1 of the beverage in the container body 1 at the time of the start of beverage intake and the calculation of the content volume V2 of the beverage in the container body 1 at the time of the end of beverage intake are completed, the next time is the time of the start of beverage intake. The predetermined amount ΔV (FIG. 16(d) ).

According to such a method of calculating the amount of beverage intake, the amount of the beverage W that has flowed out from the container body 1 of the beverage container, that is, the amount of the beverage W that has flowed out from the container body 1 of the beverage container, can be calculated without causing problems like conventional capacitive flow sensors or positive displacement flow sensors. The amount of drink consumed by the user can be calculated easily and accurately.

Next, when the calculation of the predetermined amount ΔV of beverage intake by the user is completed, the container body 1 is returned to the vertical state similar to that in FIG. 16(a), for example, as shown in FIG. 16(d). It will be done. In the state shown in FIG. 16(d), a predetermined amount ΔV of beverage W flows out from the drinking spout 12a due to an increase in the inclination angle θ (θ1 to θ2) from FIG. 16(b) to FIG. 16(c). As a result, the amount of beverage W in the container body 1 has decreased.

Then, when starting to take a new drink W from this state, for example, as shown in FIG. 16(e), in the normal case, the inclination angle θ2 of the container body 1 in FIG. 16(c) is The user starts drinking by tilting the drinker to a large angle of inclination θ3 (θ3=80 degrees).

However, depending on the amount remaining at that time, the drink may be replenished in the state shown in FIG. 16(d), for example. In that case, the user can start drinking at an inclination angle θ3 that is smaller than the inclination angle θ2 of the container body 1 in FIG. 16(c). That is, θ3 is not always larger than θ2.

However, even in this case, the intake amount is calculated by newly calculating the content volume V1 at the beginning of drinking at θ3 and calculating the difference ΔV from the content volume V2 at the end of drinking. For example, by storing the content volume V2 at the end of the previous drink and setting it as the content volume V1 at the start of the next drink, there is no need to perform residual volume correction that takes into account the replenishment volume, such as learning control that omits that calculation. , it is possible to always calculate accurate intake amounts.

(About the calculation method for the amount of beverage inside the container body depending on the inclination angle of the container body)
By the way, when calculating the predetermined amount ΔV which is the drink intake amount as described above, first, the start of outflow of the drink W at the drinking spout part 12a is detected by a photosensor consisting of a light emitting diode 52a and a photodiode 52b, which is a drink outflow detection means. The content V1 of the beverage corresponding to the inclination angle θ1 with respect to the horizontal direction of the container body 1 at the time of detection, and the amount of beverage at the spout 12a by a photosensor consisting of a light emitting diode 52a and a photodiode 52b, which is a means for detecting the outflow of the beverage. It is a premise that the content volume V2 of the beverage corresponding to the inclination angle θ2 of the container body 1 at the time of detecting the end of outflow is calculated.

The calculation of the internal volume V1 and the internal volume V2 are performed using two methods: (1) using actual measurement data; and (2) using calculated data calculated in advance. There are two ways to do this.

(1) Regarding the calculation method of the beverage content using actual measurement data (experimental data) In this method, the calculation of the beverage content V1 corresponding to the inclination angle θ of the container body 1 at the start of beverage intake, Calculation of the content volume V2 of the beverage corresponding to the inclination angle θ of the container body 1 at the end, and calculation of the predetermined amount ΔV, which is the beverage intake amount based on the difference V1-V2 between the two content volumes, are based on the pre-measured figure 15. This is done based on the measurement data (experimental data) shown. The measurement data (graph) in FIG. 15 shows the relationship between the above-mentioned inclination angle θ of the container body 1 with respect to the horizontal direction and the corresponding liquid content (remaining amount in the bottle ml).

Measurement data showing the relationship between the inclination angle θ of the container body 1 with respect to the horizontal direction and the corresponding internal volume V (remaining amount) of the liquid is, for example, as shown in FIG. The container body 1 is tilted horizontally from the vertical state (θ=0 degrees) shown in FIG. Incline the container by 5 degrees from θ1 to θ2 to θn until it reaches θn (125 degrees) (in FIG. 16, θ2 to θn are omitted), and measure the internal volume V of the liquid in the container body 1 every 5 degrees. It is created by recording and recording. In the case of the measured data in Figure 15, there are some fluctuations in the plotted values of the measured data itself, so the approximated data (see the approximate curve shown by the broken line) that is obtained by smoothing them is converted into digital data and is shown in Figure 14. The data is stored as read-only control data in the memory section (ROM side) of the control unit 51g shown in FIG.

The control unit 51g, which is a liquid outflow amount calculation means, reads out the liquid content measurement data stored in the memory section (ROM) using the inclination angle θn of the container body 1 detected by the inclination angle sensor 51b as a parameter. It is calculated as the internal volume V (remaining volume) of the liquid at that time.

When calculating the predetermined amount ΔV, which is the amount of beverage ingested by the user, when the outflow of the liquid at the drinking spout 12a is detected by the photosensor consisting of the light emitting diode 51c and the photodiode 51d, which is the liquid outflow detection means (at the time of start of outflow). Based on the liquid content V1 corresponding to the inclination angle θ1 of the container body 1 (see FIG. 16(b)), the container body 1 when the liquid outflow is not detected at the spout 12a by the photo sensor (when the outflow is finished). The content amount V2 of the liquid corresponding to the inclination angle θ2 (see FIG. 16(c)) is subtracted, and the amount of the drink actually consumed by the user is calculated from the difference ΔV (decreased amount).

By calculating the internal volume V (remaining volume) based on actual measurement data in this way, it is possible to always calculate the accurate internal volume V without errors in accordance with changes in the inclination angle θ of the container body 1. can. In addition, the liquid content V1 corresponds to the inclination angle θ1 of the container body 1 when liquid outflow is detected (at the start of outflow), and the inclination angle θ2 of the container body 1 when no liquid outflow is detected (at the end of outflow). Similarly, the predetermined amount ΔV, which is the amount of liquid flowing out from the container body 1, calculated from the difference between the amount of liquid and the content amount V2 of the liquid, that is, the calculated value of the amount of drink consumed by the user, is also accurate.

Moreover, the measurement data shown in FIG. 15 is accurately measured at intervals of 5 degrees from a state where the inclination angle θ of the container body 1 is 0 degrees to a state of 125 degrees. Therefore, even if the amount of drink consumed by the user is small, the amount of liquid at the beginning and end of drinking can be accurately calculated, and the actual amount of drink consumed can also be accurately calculated.
(2) Regarding the method of calculating the content of the drink using calculation data Next, FIGS. 17 to 21 show the method of calculating the content of the drink using the calculation data.

In FIGS. 17 to 21, in order to simplify calculations and explanations, the drinking spout 12a shown in FIGS. 16(a) to 21(e) is omitted, and only the container body 1 is shown. , the opening on the upper end side of the container body 1 is labeled with the reference numeral 12a so that the positional relationship can be understood.

The basic form of the container body 1 expressed in this way is shown in FIG. The container body 1 is a cylindrical body with a central axis O-O, a radius a, and a length L, and a beverage W (drinking water) is stored up to a predetermined height position of the liquid storage part S. . In such a container main body 1, when the container main body 1 is tilted at an inclination angle θ as shown in the figure, the container main body 1 is also inclined at a similar inclination angle θ with respect to the upper surface of the beverage W stored inside. become. Then, when the upper surface position of the beverage W becomes higher than the lower end of the drinking spout 12a (opening) of the inclined container body 1, the beverage W inside the container body 1 flows out. This state is accurately detected by turning on the photosensor made up of the light emitting diode 52a and photodiode 52b for detecting the beverage outflow described above.

As shown in FIG. 19, the case where exactly half of the total capacity of the beverage W remains in the container body 1 is used as a standard, and the three cases are the case where the amount of beverage W remains in the container body 1 as shown in FIG. A method of calculating the internal capacity V according to the inclination angle θ of the container body 1 will be explained by dividing it into patterns.

(a) When the capacity of the beverage W exceeding the capacity shown in Fig. 19 (half of the total capacity) remains in the container body 1: see Fig. 18 The content volume V (remaining amount) in this case is, for example, As shown in 18, since tanθ>2a/L and the angle between the container body 1 and the horizontal direction is θ, V=πa2(L−a·cosθ/sinθ).
(b) When half of the total capacity of the beverage W remains in the container body 1: See FIG. 19. In this case, the content V (remaining amount) is, for example, as shown in FIG. 19, tanθ=2a /L, and since the angle between the container body 1 and the horizontal direction is θ, it is determined by V=πa2L/2.
(c) When the content (remaining amount) of the beverage in the container body 1 is less than half of the total capacity shown in FIG. 19: See FIGS. 20 and 21. In this case, the content V (remaining amount) is: As shown in FIGS. 20 and 21, since 0<tanθ<2a/L and the angle between the container body 1 and the horizontal direction is θ, V=cotθ/3・(a2−x1)2/3 is required. However, x1=(a−Ltanθ)·(2aLtanθ−L2tan2θ).

The data showing the relationship between the inclination angle θ of the container body 1 with respect to the horizontal direction according to the shape of the container body 1 and the corresponding content volume V is as shown in (1) when the container body 1 is filled with a drink to its full capacity. Although it can be accurately obtained by actually tilting the container in the horizontal direction and measuring and recording the internal volume V in the container body 1 at each predetermined angle of inclination, similar data can be obtained as in (2). Alternatively, it can also be obtained by calculating the internal capacity for each predetermined angle of inclination according to the shape and dimensions of the container body 1.

That is, if the shape (cylindrical shape) and dimensions (radius a and length L) of the container body 1 are known, the volume shape change of the content liquid that changes according to the change in the inclination angle θ of the container body 1 can be calculated as described above. More accurate content data can be obtained by geometrically calculating as in (a) to (c) and by computer simulation if necessary. Then, the content data obtained by this calculation is converted into predetermined digital data as in the case of the measurement data in (1), and is stored in a predetermined memory section (ROM) of the control unit 51g.

The control unit 51g reads out the content amount data stored in the memory section (ROM) using the inclination angle θ of the container body 1 detected by the inclination angle sensor 51b as a parameter, and calculates the content amount of the beverage.

Even with such calculation data, it is possible to calculate the accurate content volume V according to the inclination angle θ of the container body 1, and the content volume of the beverage corresponding to the inclination angle θ1 of the container body 1 at the time when the beverage starts flowing out. The predetermined amount ΔV of the beverage flowing out from the container body 1 calculated by the difference V1-V2 between V1 and the content volume V2 of the beverage corresponding to the inclination angle θ2 of the container body 1 at the end of the beverage flow is also accurate. Become.
<About the structure of the beverage container according to the modification of the first embodiment in which the temperature of the beverage passing through the spout can be detected> The vicinity of the insertion hole 50 of the spout 12a in the control board 5, that is, the A beverage temperature sensor 51k (see FIG. 14) for detecting the temperature of the beverage passing through the spout portion 12a may be provided at a portion corresponding to the outer periphery, if necessary.

In this way, the temperature of the beverage passing through the spout 12a can be detected, and for example, the beverage container having the configuration of the first embodiment can be used for purposes such as baby bottles. spread.
<About a user monitoring system using a beverage container equipped with a beverage intake calculation function>
Next, FIG. 22 shows a schematic configuration of a user monitoring system configured using a beverage container (control unit 51g) equipped with a beverage intake calculation function, and FIG. Showing control flow.

As shown in FIG. 22, for example, this user monitoring system targets children in kindergartens and elementary schools as an example of beverage container users, and those users go to school carrying the beverage container 10 configured as described above and a smartphone 30. We are assuming a case where The control unit 51g of the beverage container 10 receives a predetermined cloud service from a cloud service provider via a computer network such as the Internet, for example, protects measurement data and beverage intake calculation data measured by various sensors of the control unit 51g. Receive a service for sending corresponding e-mail information, etc. from the smartphone 30 of the parent, the PC of the attending physician at the hospital (medical institution side), the smartphone 30 of the guardian, the PC of the attending physician at the hospital, etc. is now possible.

In the case of this user monitoring system, the purpose is not simply to monitor the amount of beverage intake (amount flowing out from the container body 1), but also to monitor whether or not the beverage is ingested, taking into account the external environment and physical condition at the time. User information is sent to parents and the attending physician at the hospital to determine whether or not the amount of beverages consumed is sufficient. If they are not taking it, we will encourage them to take it, and if they are taking it but it is not enough, we will ask them to take more. It is characterized by the fact that it realizes a monitoring function that gives instructions using .

In the case of the beverage container 10, as described above, dry batteries 57, 57, which are small and convenient to carry, are used as a power source for driving various sensors and the control unit 51g. However, in the case of dry batteries, the battery capacity is not necessarily large. Therefore, various sensors (devices) are designed to be as energy-efficient as possible, and long-distance communication (Sigfox communication) over low-power broadband networks (LPWAN) is possible as a communication method for computer networks. It uses a wireless module and is configured to enable reliable sensing and long-term effective communication.

Next, with reference to the control flow shown in FIG. 23, the measurement of external temperature and humidity, the measurement of the user's body temperature, the calculation of the amount of beverage intake, and the transmission control operations of these measured data and calculation data by the control unit 51g in the user monitoring system will be explained. do.

That is, in this control flow, as shown in FIG. 23, first, as a condition for starting the beverage intake calculation operation, etc., it is determined whether or not the lid 3 of the beverage container is opened based on the lid opening/closing detection signal of the lid opening/closing sensor 51a. (Step S1). If the judgment result is NO and the lid 3 is not yet opened and the lid is closed, the calculation operation is not started until the lid 3 is opened, and the open state of the lid 3 is detected at a predetermined control cycle. Repeat the action.

When the lid 3 is opened and the determination result becomes YES, the temperature and humidity sensor 51e is then used to start measuring the temperature and humidity outside the beverage container (in the room or outdoors) (step S2). As a result, it is possible to obtain data for determining whether or not a user carrying a beverage container is in an environment where the summer temperature is high and humidity is high, and there is a risk of heat stroke.

The fact that the lid 3 of the beverage container is opened can be determined to indicate that the user is about to consume the beverage inside the beverage container (inside the container body 1). Therefore, if the purpose is simply to measure the intake amount of the beverage drunk by the user (the amount flowing out from the container body 1), it is sufficient to start the calculation operation of the beverage intake amount with this as a condition. However, as mentioned above, the purpose is not simply to measure the amount of beverage ingested (the amount that flows out from the container body 1), but to determine whether or not the beverage is ingested, taking into account the external environment and physical condition at the time. Information such as whether the amount is sufficient is sent to parents and the attending doctor at the hospital as user information. Considering the external environment and physical condition at the time, and from the standpoint of heatstroke prevention, if the user has not consumed beverages, we will encourage them to do so, and if they have, but the intake is not sufficient, we will encourage them to do so. It has a monitoring function that uses the phone call and e-mail functions of smartphones and the e-mail function of PCs to give instructions so that people can consume more.

Therefore, when the lid body 3 is opened, it is necessary to first measure the temperature and humidity in the room or outdoors outside the beverage container as the usage environment of the beverage container at that time, and to ensure that the beverage is consumed in an environment where the beverage container is used at that time. I am trying to judge whether it is midsummer daytime or not.

Next, using a photosensor consisting of a light emitting diode 51c and a photodiode 51d for detecting face proximity, it is determined whether the user's face has approached the photosensor by a predetermined distance or more (step S3 ). If the result is YES, the user is in a state where he or she is about to ingest the beverage in the beverage container (container body 1) by putting his or her mouth on the spout 12a, and the user It is determined that the person's face is located at a distance where the body temperature (radiant temperature) of the person can be effectively measured. On the other hand, if it is determined that the distance between the photo sensor and the user's face is greater than a predetermined distance and the body temperature sensor 51f made of a thermopile cannot effectively measure the user's body temperature, the drinking spout The same face approach detection operation is repeated until the mouth is brought closer to the portion 12a at close range.

If the determination in step S3 is YES, the process proceeds to step S4, where the body temperature sensor 51f made of a thermopile measures the user's body temperature based on the amount of infrared radiation from the user's face. The body temperature data measured here is stored in a predetermined RAM memory built into the control unit 51g. This stored body temperature data is sent to the parents' smartphones, the attending physician's PC at the hospital, etc. using the computer network cloud service described above in step S12, which will be described later, and is used for diagnosing heat stroke and taking preventive measures. (described later).

Next, it is determined whether or not the beverage has passed through the spout 12a using a photosensor consisting of a light emitting diode 52a and a photodiode 52b for detecting beverage outflow (step S5). As a result, if the beverage actually flows out into the spout portion 12a and the determination is YES, then the inclination angle of the container body 1 when the beverage flows out is detected using the inclination angle sensor 51b (step S6). . The inclination angle of the container body 1 at the start of drinking the beverage is also stored in the RAM memory of the control unit 51g. On the other hand, if the determination is NO that the beverage has not yet flowed out into the drinking spout 12a, the detection of the beverage outflow is repeated.

After the detection of the inclination angle of the container body 1 in step S6 is completed, it is then determined whether or not the beverage has stopped flowing out of the drinking spout 12a, that is, the end of beverage intake is determined (step S7). The end of this beverage intake is also accomplished using a photosensor consisting of a light emitting diode 52a and a photodiode 52b for detecting beverage outflow.

That is, when the beverage consumption is finished and there is no more beverage in the spout 12a between the light emitting diode 52a and the photodiode 52b for detecting beverage spillage, the photosensor consisting of the light emitting diode 52a and photodiode 52b for detecting beverage spillage is activated. Changes from ON to OFF. If the result of the determination of the end of beverage intake is NO and the beverage intake is still continuing, the determination operation is repeated until the beverage intake is stopped.

On the other hand, if the ingestion of the beverage has stopped and a YES determination is made, the process proceeds to step S8, and the inclination angle of the container body 1 at the time of the YES determination (when the beverage outflow is stopped) is detected. The inclination angle of the container body 1 at the end of drinking the beverage is also stored in the memory of the control unit 51g.

Next, when the detection and memory of the inclination angle of the container body 1 at the end of beverage intake is completed, the process proceeds to step S9, and the inclination angle of the container body 1 at the time of the start of beverage intake is stored in the memory of the control unit 51g. The intake amount of the beverage (the amount of beverage actually drunk) is calculated based on the difference between the amount of the beverage corresponding to the amount of the beverage corresponding to the inclination angle of the container body 1 at the end of the intake of the beverage ( Step S9).

A method for calculating the content of the beverage corresponding to the angle of inclination of the container body 1 at the start of drinking the beverage, a method for calculating the content of the beverage corresponding to the angle of inclination of the container body 1 at the end of the intake of the beverage, and a method for calculating the content of the beverage corresponding to the angle of inclination of the container body 1 at the end of the intake of the beverage, and a method for calculating the content of the beverage corresponding to the angle of inclination of the container body 1 at the end of drinking the beverage, and the difference between the two contents. The method of calculating the amount of beverage intake based on this is as described above, and this final calculation data of the amount of beverage intake is also stored in the RAM memory of the control unit 51g.

Thereafter, it is further determined whether the lid 3 is closed (step S10), and if YES, the measurement of the temperature and humidity outside the beverage container for each control cycle described above is ended. (Step S11). On the other hand, in the case of NO, the transition from open to closed of the lid 3 continues to be detected until the lid 3 is closed.

When the lid body 3 is actually closed and the temperature and humidity measurement by the temperature and humidity sensor 51e is completed, the process finally proceeds to step S12 to calculate the temperature and humidity measurement data, the body temperature measurement data by the body temperature sensor 51f, and the amount of beverage intake. The data is transmitted to the parents and the attending physician at the hospital using the computer network cloud service using the transmitting/receiving unit 51h of the control unit 51g (step S12). The transmitted measurement data and calculation data are used to diagnose whether or not the user is suffering from heatstroke based on the external environmental temperature and humidity at that time, and the user's corresponding body temperature, and then utilizes computer network cloud services. Necessary instructions, such as to drink a predetermined amount of drinks regularly or to drink more drinks, are sent to the user's smartphone from the parent's smartphone or the PC of the attending physician at the hospital. This makes it possible to avoid heatstroke in summer for children in kindergartens and elementary schools.
<About the structure of the liquid container according to the second embodiment>
Next, FIGS. 24 to 29 show the structure of a liquid container according to the second embodiment. The liquid container according to the present embodiment is also configured as a beverage container in the same way as the liquid container according to the first embodiment, and the overall configuration including the main body structure of the beverage container and the control unit 51g is substantially the same. It is equipped with all functions such as temperature and humidity measurement function outside the beverage container, user body temperature measurement function, beverage intake calculation function, communication function, etc. Similarly, the sending/receiving unit 51h of the control unit 51g can be used to send and receive information to parents and the attending doctor at the hospital using a computer network cloud service.

However, in the structure of the stopper main body 2 according to the first embodiment, a battery storage case 53 that largely protrudes outward from the container main body 1 is provided in an angular shape on the rear end side of the stopper main body 2. In the case of such a configuration, for example, two to four dry batteries 57, 57, etc. can be stored, and although there is an advantage in that the battery capacity can be increased, the size of the plug body 2 is limited in the radial direction. There is a disadvantage that the battery storage case 53 becomes locally large outwardly and becomes an obstacle when carried or operated.

Therefore, in the configuration of the beverage container of the second embodiment, as shown in FIG. A coin-shaped battery main body 60a is installed on the wide upper surface portion of the mounting portion 12b of the drinking spout member 12 via a battery storage case 60b. As a result, the entire outer circumferential surface of the stopper body 2 is made into a cylindrical body having the same diameter as the container body 1, thereby effectively eliminating the disadvantages of the beverage container of the first embodiment.

In this case, projection plugs 15a to 15c (see FIG. 26; 15b is not shown because it is not visible) are provided at three locations on the back side of the battery storage case 60b shown in FIGS. 26 to 28. On the other hand, as shown in FIG. 29, socket portions 14a to 14c, which are recesses into which the plugs 15a to 15c are inserted, are provided at three locations on the upper surface of the attachment portion 12b of the corresponding spout member 12. This allows the button-shaped (coin-shaped) battery 60, which is circular and has a thin overall thickness, to be easily attached and detached. An electrode terminal 60c is provided at one end of the battery storage case 60b, and a lead wire for power supply is connected to the electrode terminal 60c.

In the case of the beverage container of this embodiment, since the button-shaped (coin-shaped) battery 60 is installed on the upper surface portion of the attachment part 12b of the drinking spout member 12, for example, as shown in FIGS. The lower portion of the side wall portion 22 is lengthened vertically by a predetermined dimension C (see FIG. 24) to expand the installation space in the vertical direction. Further, as a result, since the transmitting/receiving antenna 55 cannot be installed on the top surface of the attachment portion 12b of the spout member 12 as in the first embodiment, a boss 13c for supporting the antenna is separately provided (FIGS. 28 and 28). 29), and a transmitting/receiving antenna 55 is supported above the battery 60 (see FIG. 26).

In the case of such a configuration, the vertical length of the beverage container is longer by a predetermined dimension C shown in FIG. 24 than in the case of the beverage container configured in the first embodiment. It does not particularly increase the size of the beverage container since it is only a small size corresponding to the thickness of the battery 60 of the type. More than that, the entire outer peripheral surface of the stopper body 2 can be made into a cylindrical body with the same diameter as the container body 1, which is very advantageous in that there is no problem in carrying and operating it.

On the other hand, the button-shaped battery 60 is small, flat, and easy to install, but has a relatively small battery capacity compared to a dry battery. There is a slight handicap in that respect. Therefore, in this embodiment as well, the above-mentioned various sensors (devices) are made as power-saving as possible, and the communication means is long-distance communication (Sigfox communication) using a low-power broadband network (LPWAN). A wireless module capable of this is adopted, and the configuration is such that reliable sensing and long-term effective communication are possible even with a button-type battery 60 having a small battery capacity.
