Description

  The present invention relates to a fluid agitation apparatus that stirs powder and hot water of instant miso soup, instant coffee, cocoa, etc., by simply supplying hot water, and obtains instant miso soup, instant coffee, cocoa in a suitable mixture, In particular, the present invention relates to a fluid agitation device that only supplies hot water to powder contained in a container and stirs the powder supplied therein.

As this type of fluid agitating device, although it is premised that it is used in a microwave oven, a mudler that agitates by itself is known in Patent Document 1. The use of the mudler in Patent Document 1 is to open the screw-type cap on the head of the mudler, put water in it, insert the mudler into a cup containing the liquid to be warmed, and put the whole cup into the microwave oven. Turn on the microwave. After a while, the water placed in the Madler's container of Patent Document 1 boils and generates steam. The steam spouts from the nozzle and rotates the shaft. Since the screw is attached to the tip of the shaft, the screw stirs the liquid in the cup. The action eliminates the temperature difference between the liquids in the cup. The microwaves emitted from the microwave oven warm the liquid in the cup, and at the same time, boil the water in the container above the mudler in Patent Document 1 and simultaneously rotate the mudler.

It takes a little time for the water in the container to boil, and the mudler of Patent Document 1 does not rotate immediately, but the liquid in the cup is not warmed up to that point, so there is no need to stir. Moreover, the ring-shaped nichrome wire put in the container is for generating heat by the microwave and assisting the generation of steam, and may be of any nature that generates heat by the microwave. If the container itself is a material that generates heat by microwaves, there is no need to add it. The tube that adjusts the length of the nozzle is a structure in which a slightly narrower tube that is just inscribed inside is placed inside, so that the length can be adjusted. It is used for a long time when mixing viscous liquids.

Patent Document 1 can eliminate the temperature difference between the upper and lower positions that occurs when the liquid placed in a vertically long container such as a cup is heated in a microwave oven, and prevents deterioration of the quality of the liquid due to excessive warming upward, Since it rises at the same temperature, it is easy to grasp the temperature and it can be heated to the target temperature. In particular, an invention is disclosed that is optimal for powdered soups that are heated while stirring to produce smoothness, and that can be prevented from becoming lumpy when mixed after being removed from the microwave oven.

JP2002-206749

  As described above, Patent Document 1 prevents the occurrence of a temperature difference according to the position of the liquid placed in a vertically long container such as a cup without using human hands for heating performed in the microwave oven. . At this time, since the water put in the container of the Madler boils and generates a vapor | steam at this time, since the vapor | steam comes out from a nozzle vigorously and rotates a shaft | shaft, it is arrange | positioned at the front-end | tip of a shaft | shaft. The screw rotates, stirs the liquid in the cup, and eliminates the temperature difference between the upper and lower positions of the liquid in the cup.

However, since the output sharing (load) of the microwave oven is determined by the resistance of the liquid in the cup and the load of water contained in the container of the mudler, the dielectric constant, and the like, there is a time difference until the screw rotates. Also, due to the difference in the load of the liquid in the cup and the water in the Madler container, even if the microwave oven is operating, water vapor may not be ejected from the nozzle of the Madler container. Further, when water vapor is ejected from the nozzle of the Madler vessel, the hot water temperature of the Madler vessel needs to be raised to 95 ° C. or higher, and rotation does not occur at a temperature of 50 to 90 ° C. hot water. Further, when hot water is ejected from the nozzle of the Madler container in the microwave oven, there is a problem that the tan δ of the dielectric such as air and water vapor in the microwave oven changes and the heating time by the microwave oven is not stable.
Moreover, although the invention of patent document 1 presupposes the heating by a microwave oven, when stirring powder and hot water like instant food, it stirs the liquid in a cup and the liquid in a container of a mudler. If this is done, energy-saving measures can be taken.

  Therefore, the present invention eliminates such a conventional problem, performs stirring in the container with the necessary amount of hot water to be supplied, and further does not supply energy required for stirring from the outside. Providing is an issue.

Note that, in the embodiments, the same reference numerals and the same reference numerals are the same or corresponding functional parts, and therefore, redundant description thereof is omitted here.

[Embodiment]
The container 1 such as a cup, mug cup, coffee cup, tea cup or the like that can store a liquid such as hot water may be made of glass, metal, ceramics, or the like, or may be made of other materials. In this embodiment, an example of a glass cup will be described. Usually, a stainless steel mug or the like having a wide bottom area and high self-supporting stability is used.

A base body portion 10 serving as a basic portion of the main body constituting the fluid stirring device of the present embodiment is placed on the open end 1a of the container 1. The base portion 10 is formed of a synthetic resin, and the position in contact with the opening end 1a of the container 1 is formed of a soft synthetic resin, and the other portions are formed of a hard synthetic resin. In detail, the position which contacts the opening end 1a of the container 1 is tapered so as to be a free size that fits various dimensions, not just a specific size. By making this taper, it comes into close contact with the open end 1a of the container 1 and there is no liquid leakage. Of course, when implementing this invention, it can also be set as the container 1 for exclusive use, such as a mug.

The agitation unit 20 accommodated in the accommodation container 1 has an agitation function of rotating horizontally in the liquid around the vertical axis. The stirring unit 20 includes a central member connected to the rod unit 30 at the center and a stirring member 21 disposed around the central member in a U-shape every 90 degrees, 45 degrees, or 30 degrees. The stirring member 21 may have the same shape, but it is desirable to divide the distance from the center of the stirring unit 20 into several parts. In view of the balance of the stirring unit 20, a combination of two types and three types of lengths is desirable. If the distance from the center of the stirring unit 20 is divided into several parts, not only stirring at a specific distance from the center of the stirring unit 20 is performed at the time of stirring, but a wide range of stirring is possible. Moreover, the magnitude | size of load becomes those average values, and efficient stirring is attained.

The rod unit 30 that rotates the stirring unit 20 about the vertical axis is mechanically connected to the center of the stirring unit 20. This rod part 30 transmits rotation of the impeller part 40 mentioned later to the stirring part 20, and is a solid round bar in this Embodiment. The lower end of the rod portion 30 has a pointed axis, and is pivoted even if it contacts the bottom surface of the container 1. Of course, a hemispherical state may be used. The lower end of the stirring unit 20 is positioned within a range of 2 to 10 mm from the lower end of the rod unit 30. In addition, although the up-and-down width of the stirring part 20 is 20-40 mm, it should not maintain this numerical value strictly.

An impeller portion 40 having a rotating blade 41 is disposed on the upper portion of the rod portion 30. The rotating blade 41 of the impeller unit 40 obtains a rotational force that rotates about the vertical axis of the rod unit 30 by the fluid supplied in the tangential direction of the circle drawn at the center of the vertical axis of the rod unit 30. It is mechanically connected and is attached to the base portion 10 so as to be rotatable. More specifically, the impeller portion 40 has a plurality of blades, and in the present embodiment, a total of 12 rotating blades 41 are provided every 30 degrees, and the center of the impeller portion 40 is a thrust bearing. The cylindrical shaft 42 accommodates 43, and a thrust bearing 43 is disposed on the cylindrical shaft 42, so that the rotating blade 41 of the impeller unit 40 can freely rotate. The thrust bearing 43 receives the rotating blade 41 by the receiving member 44 so that the rotating blade 41 can be smoothly rotated even if the load of the rotating blade 41 is applied.

The total 12 rotating blades 41 of the impeller unit 40 determine the shape of each rotating blade 41 so that the liquid flow from the injection port 51 of the fluid supply unit 50 described later collides with the surface at a right angle. ing. The impeller part 40 receives the load by the thrust bearing 43. That is, the lower part of the thrust bearing 43 disposed in the impeller portion 40 is received by the receiving material 44. The receiving material 44 shown in FIG. 1 is connected between a ring-shaped outer ring 44a having a fan-shaped opening and a cylindrical shaft 42 by a plurality of connecting bodies 44b.
In this manner, the opening of the receiving member 44 is easy to drop down the hot water supplied from the fluid supply unit 50, and a holding force is applied so that the thrust bearing 43 is fixed at a predetermined position. In the present embodiment, a screw 44c that is screwed onto the outer periphery of the receiving member 44 is formed and tightened by the screw 44c. However, when the present invention is implemented, the screw 44c is bonded to the base 10 or the fluid supply unit 50. You may join with an agent.
The rotating blade 41 of this embodiment, the cylindrical shaft 42 at the center of the rotating blade 41, the thrust bearing 43 accommodated therein, and the receiving member 44 that receives the lower portion of the thrust bearing 43 constitute the impeller portion 40. Yes.

  The upper opening area of the impeller portion 40 is wide, and the opening area of the injection port 51 that causes the fluid to collide with the rotating blade 41 of the impeller portion 40 is narrowed to obtain the rotational force of the impeller portion 40. A fluid supply unit 50 that supplies fluid is disposed. The fluid supply unit 50 has a large opening area as a pouring spout. Further, the opening of the ejection port 51 that collides with the rotary blade 41 of the impeller unit 40 is determined so that the velocity of the fluid stored in the fluid supply unit 50 can be obtained. Usually, the fluid supply unit 50 increases the injection speed from the injection port 51 and does not function as a storage tank.

The ejection port 51 of the fluid supply unit 50 is provided at the lowermost part of the fluid supply unit 50 and is a position that collides perpendicularly with the radial extension of the rotary blade 41 of the impeller unit 40. The outer peripheral position of the surface of the rotary blade 41 of the impeller unit 40 is disposed. When viewed from the impeller unit 40, the nozzle 51 that causes the fluid to collide with the rotating blade 41 of the impeller unit 40 draws the fluid flow that obtains the rotational force of the impeller unit 40 by the rotating blade 41 of the impeller unit 40. Fluid is supplied tangentially to the circle. The outermost periphery of the rotary blade 41 forms an annular ring 41a in order to ensure mechanical strength. Accordingly, the injection port 51 that causes the fluid to collide with the rotating blade 41 of the impeller portion 40 is disposed within the inner diameter of the outer annular ring 41a.
If the position of the injection port 51 that causes the fluid to collide with the rotary blade 41 of the impeller portion 40 is separated from the center of the impeller portion 40 by a distance L ₄ , the average position L ₂ of the stirring member 21 of the stirring portion 20. The relationship is L ₄ ≧ L ₂ .

L ₄ ≧ L ₂ is set such that the moment of force is set larger on the impeller portion 40 side and smaller on the stirring portion 20 side so that the rotation between the stirring portion 20 and the rotary blade 41 of the impeller portion 40 becomes smooth. Is set to Since the thrust bearing 43 does not want to increase the contact resistance in that sense, one having a low frictional resistance is used.
However, since it is desirable that the moment of force on the impeller portion 40 side is large, the position of the injection port 51 that causes the fluid to collide with the impeller portion 40 is the maximum distance (radius) from the center of the rotating blade 41 of the impeller portion 40. ) apart, it is desirable to increase the distance L ₄ away from the center of the impeller 40.

The thrust bearing 43 disposed in the center of the impeller portion 40 has a bottom surface held by a receiving member 44, and the rod portion 30 passes through the center of the thrust bearing 43 in the center. The relationship between the rod part 30 and the impeller part 40 may be a connection in which the rod part 30 directly transmits the rotation of the impeller part 40 as shown in FIG.
Further, as in the modification shown in FIG. 4, when the rod portion 30 is a bar formed in a triangular triangular cross section (it may be a bar formed in the number of corners equal to or greater than the triangular cross section) The rod part 30 and the impeller part 40 are connected via a bush 45a made of rubber or synthetic resin having cushioning properties. The rotational force can be transmitted from the impeller portion 40 to the rod portion 30 by the bush 45a. However, if the rod part 30 is pushed or pulled in the length direction, the apex position of the rod part 30 can be prevented from coming into contact with the bottom surface of the container 1. In addition, the position can be arbitrarily changed. Furthermore, vertical stirring can be performed.
That is, the bush 45a can have a function of stirring at a specific position if the thrust bearing 43 has a circular inner diameter and the rod portion 30 is a round bar. Further, by causing a slight slip between the thrust bearing 43 and the inner diameter of the thrust bearing 43, the rod portion 30 can be moved up and down.

Further, as shown in FIGS. 5, 6, and 7 (a), by forming a groove in the length direction around the rod portion 30 a and the rod portion 30 b, the rod portion 30 and the rotary blade 41 can be compared with each other. Although rotation is impossible, it can be set as the structure which moves up and down smoothly.
Further, the rod portion 30b or the rod portion 30c shown in FIGS. 7 (a) and 7 (b) has a linear shape in the length direction of 20 to 50 mm and a spiral of one rotation, and the bush 45 is made of metal or synthetic resin. By doing, it can be set as the stirring part 20 which rotates in a liquid. That is, when the longitudinal groove formed on the outer periphery of the rod portion 30a or the rod portion 30b and the rod portion 30c is fitted between the bush 45a or the bush 45b so as to be movable up and down, the stirring portion 20 is rotated. However, it is possible to freely move up and down.

In addition to the relationship between the impeller unit 40 and the mechanically connected rod unit 30, this mechanism may have the functions shown in FIG. 7 between the rod unit 30 b and the rod unit 30 c and the stirring unit 20. it can.
For example, by using a longitudinal groove formed in the outer periphery of the rod part 30 or a polygonal steel bar shown in FIG. It can also be set as the part 30c.
Further, as shown in FIG. 7B, two or more multiple ball screws are used as the rod portion 30c, and the stirring portion 20 is engaged with the rod portion 30c. When lowered, the agitating part 20 fitted to the longitudinal spiral formed on the outer periphery of the rod part 30c is slidable in the longitudinal direction of the rod part 30c and can be rotated and moved. It becomes.
That is, the rod portions 30, 30 a, 30 b and the rod portion 30 c mechanically connected to the rotary blade 41 of the impeller portion 40 are agitated by two or more strip ball screws formed on the outer periphery of the rod portion 30 c. Since 20 rotates and raises by rotation of the rod part 30b, the stirring part 20 can stir upward from the bottom part of the container 1 without staying at stirring of the same depth. Thereby, a wide range of stirring can be performed. In addition, the rod portion 30c is initially rotated by contact resistance between two or more ball screws formed on the outer periphery of the rod portion 30c and the shaft hole of the impeller portion 40. Can be moved. In particular, the rod portion 30c having a plurality of strips is self-rotating because the force of the plurality of strip ball screws and the stirring portion 20 is balanced.

Although the impeller unit 40 is rotatably arranged with respect to the fluid supply unit 50, the base unit 10 is made of a hard synthetic resin except for a position where it is placed on the opening end 1 a of the base unit 10. 10 may be arranged. That is, since the impeller unit 40 is located below the fluid supply unit 50 located on the upper side and located above the base unit 10, the impeller unit 40 is integrated with either the fluid supply unit 50 or the base unit 10. May be.
In the first place, the base unit 10, the impeller unit 40, and the fluid supply unit 50 may be integrally molded with a hard synthetic resin or bonded with an adhesive, except that the impeller unit 40 is rotatably arranged. Also good. Moreover, you may connect mechanically.

Next, operation | movement of the fluid stirring apparatus of this Embodiment is demonstrated.
First, the fluid stirring apparatus of the present embodiment places the base portion 10 on the open end 1a of the storage container 1 that stores the liquid. At this time, since the base part 10 side has a narrow taper on the lower side, it fits into the open end 1a of the container 1 and is closely joined. If hot water is supplied in this state, there is no gap between the container 1 and the base 10 to release the pressure. Therefore, the leak path 11 shown in FIG. 3 is usually formed on the base 10 to suppress the pressure rise. Yes. Even if the leak path 11 is not formed, it can be discharged from the periphery of the rod portion 30.
In particular, since the base portion 10 is placed on the open end 1a of the container 1 that can store liquid, when the vehicle is stopped at an intersection during operation of the vehicle, if the fluid agitator is set, the vehicle will shake during traveling. However, the contained liquid will not leak or spill. Of course, when the present invention is carried out, the base portion 10 may be in a form that holds the container 1.

  Here, when hot water is supplied from the fluid supply unit 50, hot water is injected from the injection port 51. Since the hot water injected from the injection port 51 collides with the rotating blade 41 of the impeller unit 40, the impeller unit 40 starts to rotate and increases the rotation speed. Since the impeller portion 40 reduces the load on the rod portion 30 side by the thrust bearing 43, the rotational energy generated in the impeller portion 40 is transmitted as the rotation of the stirring portion 20 through the rod portion 30. The stirring unit 20 is stirred using the rotational energy generated in the impeller unit 40.

  That is, the stirring unit 20 accommodated in the container 1 is mechanically connected to the rod part 30 and is rotatable in the liquid around the vertical axis of the rod part 30. Moreover, the rod part 30 connected to the stirring part 20 has the upper part of the rod part 30 attached to the rotary vane 41 of the impeller part 40, and the rotary vane 41 of the impeller part 40 is fluid in the tangential direction. Is supplied. Therefore, the rotational energy generated in the impeller unit 40 is transmitted as the rotation of the stirring unit 20 through the rod unit 30, and the stirring unit 20 uses the rotational energy generated in the rotary blade 41 of the impeller unit 40 to stir the member 21. With stirring.

At this time, the fluid such as hot water that obtains the rotational force of the rotating blade 41 of the impeller unit 40 is supplied from the fluid supply unit 50 having a wide upper opening area. However, even when hot water is supplied from a heat retaining pot such as a thermos bottle or a stainless steel pot or a kettle pot, hot water is not leaked from the fluid supply unit 50 because it is easily received.
Moreover, it is made easy to take out the speed and potential energy of the hot water supplied from the fluid supply part 50 so that the fluid which protrudes from the injection nozzle 51 which narrowed opening area with the rotary blade 41 of the impeller part 40 collides. Therefore, the kinetic energy can be used efficiently.

The rotation of the rotating blade 41 of the impeller unit 40 is transmitted to the stirring unit 20 accommodated in the container 1 connected to the rod unit 30, and the stirring unit 20 rotates in a liquid such as hot water, so that the powder in the hot water The combination of powder and hot water is not necessarily required, and may be one of hot water or cold water, powder, a combination of particles, or both. Also, it doesn't matter whether or not it contains ingredients like instant miso soup.
Further, since the characteristics of the object to be stirred vary depending on the shape of the stirring unit 20, the stirring member 21 can be frame-shaped, fork-shaped, plate-shaped, or screw-shaped.

  Thus, powder and hot water, such as instant coffee and cocoa, and hot water can be stirred in the storage container 1 by the stirring unit 20 to obtain a desired mixing condition. In particular, as the fluid for obtaining the rotational force of the rotating blade 41 of the impeller unit 40, the opening area is narrowed from the fluid supply unit 50 having a large upper opening area to the rotating blade 41 of the impeller unit 40, and the injection port 51 Since the fluid is caused to collide with each other, the stirring unit 20 rotates in a specific direction without being reversed, and the contents of the container 1 can be stirred.

A fluid supply unit 50 is provided.

  In the fluid agitation apparatus according to the present embodiment, the base body portion 10 serving as a base is placed on the open end 1a of the container 1 that can accommodate a liquid. The stirring unit 20 accommodated in the storage container 1 is mechanically connected to the rod part 30 and is rotatable in the liquid around the vertical axis of the rod part 30. Moreover, the rod part 30 connected to the stirring part 20 has the upper part of the rod part 30 attached to the impeller part 40, and the impeller part 40 is supplied with fluid in the tangential direction. At this time, the fluid for obtaining the rotational force of the impeller unit 40 is supplied from the fluid supply unit 50 having a wide upper opening area, and protrudes from the injection port 51 whose opening area is narrower than the rotary vane 41 of the impeller unit 40. And the rotation of the impeller unit 40 is transmitted to the stirring unit 20 accommodated in the container 1 connected to the rod unit 30, and the stirring unit 20 rotates in the liquid to perform stirring.

  Therefore, the powder such as instant coffee and cocoa and hot water can be stirred in the container 1 by the stirring unit 20 so that the powder and the like can be mixed as desired. In particular, as the fluid for obtaining the rotational force of the rotating blade 41 of the impeller unit 40, the opening area is narrowed from the fluid supply unit 50 having a large upper opening area to the rotating blade 41 of the impeller unit 40, and the injection port 51 Since the fluid which protrudes from is made to collide, the stirring part 20 rotates in a specific direction without reversing, and the contents of the storage container 10 can be stirred. Further, the rotary blade 41 used for stirring in the stirring unit 20 is not limited to the one opened as in the present embodiment, and any plate-shaped one, coil-shaped one, frame-type one, etc. Can be selected.

The formed ball screw can be rotated and raised simultaneously. However, the rotation of the stirring unit 20 with respect to the ball screw and the sliding resistance of the outer periphery of the rod part 30c are large, and it is difficult to set conditions for starting up. However, in this type of embodiment, the stirring unit 20 can perform upward stirring from the bottom of the container 1 without being limited to stirring at the same depth. Thereby, a wide range of stirring can be performed. Moreover, it can be made to function by the contact resistance of the ball screw and impeller part 40 which were initially formed in the outer periphery of the rod part 30c. In particular, the rotation of the stirring unit 20 with respect to the ball screw reduces the sliding resistance of the outer periphery of the rod portion 30c, and the timing of starting to rise is close to the end of the supply of heat or the like, so that the entire stirring can be performed satisfactorily.

As another embodiment of the present embodiment, the stirring portion 20 that rotates in the liquid around the rod portion 30 has a rod portion 30b that is mechanically connected to the impeller portion 40, as shown in FIG. As shown in the perspective view of the main part a), the stirring part 20 can be raised and lowered manually by a longitudinal groove formed on the outer periphery of the rod part 30b.

The stirring unit 20 that rotates in the liquid around the vertical axis of the fluid stirring device of the present embodiment has a rod portion 30c that is mechanically connected to the impeller portion 40 and is formed on the outer periphery of the rod portion 30c. The shaft in the impeller portion 40 fitted to the longitudinal groove formed on the outer periphery of the rod portion 30c is connected to the rod portion 30c. Since it is slidable only in the length direction, it can be freely raised and lowered as required.

In the fluid stirring device of the present embodiment, the stirring unit 20 and the impeller unit 40 are formed so that the distance from the rod unit 30 is smaller than that of the impeller 40 by the stirring unit 20.
Accordingly, the distance from the center of the rod portion 30 of the stir portion 20 and the impeller portion 40 of the fluid-agitating device of the present embodiment, the distance L ₂ of the stirring portion 20 is shorter than the distance L ₄ of the impeller portion 40 since those formed, increases the moment of force applied to the impeller portion 40, the distance L ₂ of the stirring portion 20 is because shorter than the distance L ₄ of the impeller 40, the stirring portion 20 of the impeller 40 According to the control, the stirring unit 20 can be rotated with a moment of several times the force.

The fluid agitation device according to the present embodiment includes a base 10 placed on the open end 1a of a container 1 that can contain a liquid, and a rotary blade 41 of an impeller 40 that is rotatably attached to the base 10. When,

In the case where the base unit 10 placed on the open end 1a of the storage container 1 capable of storing the liquid of the fluid stirring device of the present embodiment is dedicated to the specific storage container 1, a structure that matches the form It can be. In the embodiment, the soft synthetic resin and the hard synthetic resin are distinguished from each other. However, when the present invention is implemented, they may be used without distinction.
Further, the stirring unit 20 housed in the storage container 1 and rotated horizontally in the liquid around the vertical axis is also made of a metal such as stainless steel or a synthetic resin material of the stirring member 21 having characteristics matching the stirring target. It can be a shape.

And the rod part 30 mechanically connected to the center of the stirring part 20 in order to rotate the stirring part 20 around the vertical axis can also arbitrarily set materials and shapes such as metal and synthetic resin.
Furthermore, in the fluid agitation apparatus of the present embodiment, the rod portion 30 is mechanically coupled with the rod portion 30 to obtain a rotational force that rotates the rod portion 30 about the vertical axis by the fluid supplied in the tangential direction of the circle around the vertical axis of the rod portion 30. The impeller unit 40 that is connected and rotatably attached to the base unit 10 efficiently applies a rotational force to the rod unit 30, and is rotatably attached to the base unit 10 or the fluid supply unit 50. I just need it.
In addition, the upper opening area is large, the opening area of the injection port 51 that causes the fluid to collide with the rotary blade 41 of the impeller unit 40 is narrowed, and the fluid that supplies the fluid flow that obtains the rotational force of the impeller unit 40 is supplied.

The base unit 10 used in the above embodiment has been described with the configuration in which it is placed on the open end 1a of the storage container 1 capable of storing a liquid. In particular, when it is brought into a vehicle or the like, it is convenient because instant coffee, cocoa, soup and the like can be made and drinked simply by supplying hot water from a pot or the like during the stop time at the intersection.
However, the basic structure of the base portion 10 can be expected to operate without error if the container 1 that can store liquid is held. However, in the case of a vehicle, there is an advantage that a situation where hot water is spilled does not occur when it is placed on the opening end 1a.
Moreover, although the rod part 30 makes the rod itself solid, a hollow thing can also be used. A hollow material is likely to be a metal because of its mechanical strength, but a synthetic resin may be curved even if it is solid, and its cross-sectional shape needs to be thermodynamically stabilized.
