Description

  The present invention relates to a plastic hot water bottle having a substantially disc-shaped hot water bottle body and having a structure in which a pouring port for pouring hot water is provided in the center of one surface of the hot water bottle body.

  Hot water bottles are attracting attention as so-called ecological heating appliances that do not require electric power, and various materials and shapes are commercially available. Among them, the plastic hot water bottle has a problem that it is deformed as it is heated by hot water and then naturally cooled, but this point is generally solved by Japanese Patent No. 4133871. Another undesirable matter is the problem of low temperature burns (low temperature burns). Low temperature burns are one type of thermal burn, and are defined as burns caused by a low temperature heat source. They are damaged by direct contact with a low temperature heat source for a long time. According to some data, the temperature of the contact part is about 6 to 10 hours. It is supposed to be injured.

  Therefore, as long as the hot water bottle is used at a temperature higher than the body temperature, it is a low-temperature burn that cannot be avoided. Also, not only hot water bottles, but all heaters that come into contact with the human body should be related to low-temperature burns.

  Therefore, the inventor of the present case does not need electric power, and earnestly researches with the recognition that in order to use a hot water bottle that is an ecological heating appliance more comfortably, this low temperature burn problem cannot be avoided. As a result, the present invention has been completed. In other words, the present invention is proposed as one of the measures for preventing the low-temperature burn caused by the hot water bottle whose temperature cannot be controlled by the inventor who has been engaged in the production of the hot water bottle for many years.

Japanese Patent No. 4133871

  The present invention has been made on the basis of the above points, and an object of the present invention is to realize a hot water bottle that hardly induces low-temperature burns by improving the shape and structure of the hot water bottle body. In addition, another object of the present invention is to provide a hot water bottle which can give a hot water bottle a form in which it is difficult to keep a body part such as a foot on the hot water bottle, thereby solving problems in use such as low temperature burns. is there.

In order to solve the above-mentioned problems, the present invention is a plastic hot water bottle having a substantially disc-shaped hot water bottle main body and having a structure in which a pouring port for pouring hot water is provided in the center of one surface of the hot water bottle main body. In addition, a recess is formed inside the ridge line surrounding the pouring spout on one side of the hot water bottle main body, and the pouring gate rises from the concave portion, and it is poured so that it slides down when a part of the body such as a foot is placed on the hot water bottle main body. The outer surface of the recess surrounding the gate is composed of a smooth curved ridge, and the center of the other surface of the hot water bottle body is also surrounded by a ridge line. configure outwardly smooth curved surface from the ridge line, the annular ridge of the hot water bottle body other surface is provided substantially symmetrical annular ridge hot water bottle body one side, leading to the outer peripheral edge from the edge line Plane in which it took measures that the cross-sectional shape of the hot-water bottle body periphery to have sufficient drop generally assumed to be formed in an elliptical shape.

  The hot water bottle of the present invention has a substantially disc-shaped hot water bottle body. The almost disc-shaped hot water bottle body means that the shape of the hot water bottle body is almost circular, and it is well known that hot water is accumulated inside the almost disk-shaped hot water bottle body. It is. The disk for constituting the hot water bottle main body is formed in a thick disk shape having a sufficient thickness because of the necessity of morphological improvement based on the present invention and the accumulation of a necessary amount of hot water.

  A recess is formed inside the annular ridge that surrounds the pouring spout on one side of the hot water bottle body (the upper surface when it is in use), and the pouring gate rises from the recess, and a body part such as a foot is placed on the hot water bottle body. It is assumed that the outside is configured with a smooth curved surface from the ridge line of the concave portion on one side surrounding the pouring gate so as to slide down. A ridge line surrounding the pouring gate is provided at the center of the hot water bottle body to improve the structural strength. In addition, the concave part inside the ridge line is provided on one side of the hot water bottle body so that the cap that closes the pouring gate does not protrude too much from the upper surface of the hot water bottle body, for the attachment and detachment operation of the cap There is also a role as a space.

  Since hot water bottles are supposed to be used by putting them in a cover or wrapping them with a towel or the like, it is impossible to touch the skin directly. During use, a body part such as a foot is placed on the upper surface of the hot water bottle wrapped with a towel or the like to warm it, but in the present invention, a part of the body such as a foot placed on the body easily slides down from there. For this purpose, the outer side is constituted by a smooth curved surface from the ridge line of the concave portion on one surface surrounding the pouring gate. If you put your feet etc. on the top of the hot water bottle body, it will slide down if you make it with a smooth curved surface, so you can not keep your feet etc on for too long time, so it is difficult to induce low temperature burns This is based on the idea. In order to make it easier for some parts of the body, such as feet, to slip off, a drop in the curved surface between the central part and the peripheral part of the upper surface of the hot water bottle body is also required along with the smoothness of the curved surface. Given by sufficient thickness (height).

  An annular ridge line that surrounds the pouring gate is the upper end of the outer wall that forms the recess. If the shape of the periphery of the recess is like a volcano, it means the ridge line of the portion that hits the outer ring with respect to the pouring gate that hits the crater. The top of the hot water bottle has a cap in the center and a recess around it, but the outer part of the ridge line of the recess is made of a smooth curved surface. The mechanism for preventing the onset of low-temperature burns in the present invention is that it is easy to slide down even if it is placed on the upper surface, and therefore cannot be put on for a long time, and thus does not lead to the onset of low-temperature burns.

  In addition, the present invention is characterized in that a concave portion surrounded by a ridge line is formed in the central portion of the other surface of the hot water bottle body (the lower surface in use), and the outer side is configured with a smooth curved surface from the ridge line of the concave portion of the other surface. And The ridgeline on this other surface is the upper end of the wall that forms a recess as in the case of one surface, and it is a part that can be compared to the outer ring of a volcano. This ridgeline is also used to improve the structural strength at the center of the hot water bottle body. Provided. Therefore, the annular ridge line on the other side of the hot water bottle body is provided almost symmetrically with the annular ridge line on the whole surface of the hot water bottle body, and the portion where the structural strength is enhanced on both sides of the central part of the substantially disk-shaped hot water bottle body. It is composed. The concavo-convex structure consisting of ridges and recesses on both sides of the hot water bottle body is provided so as to penetrate the disk-shaped hot water bottle body at the center, so that the disk-like shape that will be most affected by pressure changes due to temperature drop It is very effective for improving the strength of the center of the hot water bottle body. Further, a concave-convex structure consisting of a concave line and a convex shape extending in the radial direction from the annular ridgelines on both sides is also provided for improving the structural strength.

  Also, on the lower surface of the hot water bottle main body, the outside is configured with a smooth curved surface from the ridgeline of the outer periphery of the recess, when the hot water bottle is placed on the futon during use, the soft duvet collapses and tilts easily, and The purpose is to increase the inclination. Since the inclination of the smooth curved surface is strong, it is another requirement of the mechanism of the present invention that it is difficult to keep feet etc. on the hot water bottle, thereby preventing cold burns more effectively. Achieved. The smooth curved surface of the concave part on the other side does not cause the feet to slide off, but it is effective to give a drop in the curved surface with sufficient thickness of the hot water bottle body because it enhances the inclination tendency of the hot water bottle body. In the unlikely event that the hot water bottle body is used upside down, it will be difficult to keep the feet on the hot water bottle in the same way as on the other side.

  The recesses on one side and the other side of the hot water bottle main body are closed when the top of the hot water bottle body is closed with a cap so that the other hot water bottle is stacked on the upper surface of the hot water bottle. It is assumed that the pouring spout portion closed by the cap of the lower hot water bottle is settled and has a size and shape to be engaged. With this configuration, a plurality of hot water bottles can be engaged with each other in a single hot water bottle space and can be stably stacked, and the problem of location blockage at the time of storage at home or product display at a store does not occur.

  In addition, the recesses on one side and the other side of the hot water bottle main body are also formed with a deformation prevention structure in the center of the disk-shaped hot water bottle main body. It is a desirable configuration to have a substantially symmetrical structure in the cross section of the body. That is, if the concave portion on one side of the hot water bottle main body and the concave portion on the other surface have substantially the same shape and size, and the cross-sectional shape is substantially symmetrical, heating and cooling are similarly performed on both sides of the hot water bottle main body. Therefore, providing recesses on both sides of the central portion of the hot water bottle main body to give a substantially symmetrical structure is extremely effective as a measure for thermal deformation.

  Furthermore, the hot water bottle main body has a circular planar shape, and a plurality of protrusions are provided on the outer periphery of the hot water bottle main body as support legs for placing the hot water bottle main body in an upright position. In this invention, the “standing hot water bottle” that is a feature of the applicant's product can be applied. By setting the above protrusions to a minimum and setting the litter inside the circumference of the hot water bottle body, it is possible to obtain a disk-shaped hot water bottle with almost no protrusion outside the circumference. .

  Since the present invention is configured and operates as described above, it is expected that a mechanism will not be put on for a long time even if a foot or the like is placed on the upper surface of the hot water bottle body during use, and therefore, a low-temperature burn does not occur. It is possible to provide a hot water bottle that is difficult to induce low-temperature burns. In addition, according to the present invention, the hot water bottle that repeats heating and cooling can be significantly reduced in deformation, can solve technical problems, and can also substantially solve problems in use such as low-temperature burns. Can be provided.

  Hereinafter, the present invention will be described in more detail with reference to the illustrated embodiments. FIG. 1 shows an example of a hot water bottle 10 according to the present invention, in a standing state. Reference numeral 11 denotes a substantially disc-shaped hot water bottle main body, and a pouring port 12 is provided at the center of one surface, and a recess 13 surrounding the pouring port 12 in an annular shape is formed. The surface with the pouring gate 12 is one surface of the hot water bottle main body 11 and is the upper surface when in use. Therefore, the surface without the pouring gate is the other surface, and the lower surface when in use.

  A male screw portion 12 a is formed on the outer periphery of the pouring port 12, and the female screw portion 14 a formed on the inner periphery of the cap 14 is screwed therewith to close the pouring port 12. In the illustrated example, the cap 14 has a flat upper surface 14 b, and in a use state in which the pouring gate 12 is closed by screwing, the upper surface 14 b of the cap 14 is an annular ridge line that is the upper end of the inclined wall forming the recess 13. It is in a positional relationship slightly above 13a (see FIG. 4). Note that the cap upper surface 14b of the cap 14 does not need to be flat, and may be a curved surface such as a convex lens.

  The hot water bottle main body 11 is configured by a smooth curved surface 15 on the outer side from an annular ridge line 13a surrounding the pouring port 12 on the outer periphery of the concave portion so as to slide down when a part of the body such as a foot is placed on the one surface side. . The smooth curved surface 15 is provided with a concavo-convex structure 16 consisting of alternately arranged radial ridges 16a and ridges 16b, but is provided together with an annular ridge 13a to resist thermal deformation, The concave stripes 16a and the convex stripes 16b are shallow and do not impair the smoothness of the curved surface 15. In addition, although it is convenient for the engaging structure mentioned later that the protruding line 16b does not reach the ridgeline 13a, the recessed line 16a may reach the ridgeline 13a of the hot water bottle main body 11.

  The hot water bottle main body 11 has a concave portion 17 formed at the center of the other surface, and the outer side of the annular ridge line 17 a surrounding the concave portion 17 of the other surface is formed by a smooth curved surface 18. The smooth curved surface 18 on the other surface side is also provided with a concavo-convex structure 16 ′ composed of concave ridges 16 a ′ and ridges 16 b ′ arranged alternately in the radial direction along with the annular ridge line 17 a in the same manner as the one surface side. Yes. The annular ridge line 17a remains the upper end of the wall forming the recess 17, but the other wall is not an inclined wall like a single wall. That is, when another hot water bottle 10 is stacked on the upper surface of the hot water bottle 10 in a state where the pouring spout 12 on the one surface of the hot water bottle main body 11 is closed with the cap 14, The cap 14 that closes the pouring port portion of the hot water bottle main body 11 has a size and shape that can be accommodated (see FIG. 8). The ridges 16b and 16b 'can be said to correspond to radial ridgelines with respect to the annular ridgelines 13 and 17.

  The hot water bottle main body 11 has a concave portion 13 on one side and a concave portion 17 on the other side, and has a substantially symmetrical structure in cross section by making the size and form of both concave portions 13 and 17 substantially equal. (See FIG. 5 to FIG. 7). The meaning is to form approximately the same recesses 13 and 17 on both sides of the hot water bottle main body 11, thereby maintaining the symmetry of the hot water bottle main body structure, thereby improving heat resistance. In addition, while the concave portion 13 on one side has an inclined wall surface, the concave portion 17 on the other side is considered to be more rigid rather than that, but the concave portion on the one side has irregularities of the pouring spout 12 so that it is rigid. Is high and therefore the balance of both sides is maintained.

  In the present invention, it is possible to stack other hot water bottles 10 on the upper surface of the hot water bottle 10 as described above. For this stacking, in the example shown in the figure, a slight shallow concave portion 17b and a small convex portion 17c are annularly formed on the outer periphery of the annular ridge line 17a on the other surface so that the ridge line 13a of the concave portion on one surface is fitted and engaged with each other. This is intended to stabilize the stack. In addition, the annular ridge line 17a and the annular small convex portion 17c on the other surface form a double convex structure inside and outside, which contributes to the improvement of heat resistance of the hot water bottle main body 11.

  Furthermore, in the present invention, the hot water bottle main body 11 has a circular planar shape, and a plurality of protrusions 19 are provided on the outer peripheral edge 11 a as support legs for placing the hot water bottle main body 11 upright. A hand 20 is provided at a position approximately 180 degrees apart on the circumference. A total of four protrusions 19 are provided on both sides of the hot water bottle main body 11 across the outer peripheral edge 11a. The degree of outward protrusion from the outer peripheral edge 11a is suppressed to a minimum. Further, by providing the finger insertion port 21 on the inner side of the outer peripheral edge 11a of the hot water bottle main body 11, the hand 20 realizes a disk-shaped hot water bottle 10 having almost no protrusion beyond the circumference. The disc-shaped hot water bottle 10 with almost no protrusion provides the advantage of adjusting the outer shape and making it easy to tilt.

  As described above, the disk constituting the hot water bottle body 11 is formed into a thick disk having a sufficient thickness because of the necessity of morphological improvement based on the present invention and the accumulation of a necessary amount of hot water. is there. For example, in the case of a hot water bottle 10 having a capacity of 1.8 liters, the diameter of the hot water bottle main body 11 is about 23 cm and the thickness is 8 to 9 cm. The curvature radius of the curved surface 15 and the smooth curved surface 18 of the other surface was 4 to 10 cm, but these numerical values are examples. For the smooth curved surfaces 15 and 18, in addition to the morphological conditions described so far, it is also effective to treat the surfaces so that the feet and the like can be easily slid. The hot water bottle 10 has a capacity of 1.8 liters because the standard capacity of kettles used at home is about 2 liters. For a 2 liter kettle, a 1.8 liter hot water bottle is used. An amount of hot water that fills up to 10 can be boiled at one time. Therefore, it is possible to obtain an advantage that it is possible to prevent deformation due to too little hot water.

  According to the hot water bottle 10 of the present invention configured as described above, when the user puts it at the foot of the floor, the hot water bottle 10 is inclined to be placed on a soft futon with a smooth curved surface 18 on its lower surface, and is also used. Even if a person touches a part of the body such as a person's foot, the inclination tends to change easily. Usually, the hot water bottle 10 is covered with an appropriate cloth. However, the hot water bottle 10 of the present invention is a smooth curved surface with a sufficient drop 15 in the curved surface 15 and acts so that the foot will eventually slip even when covered, thus preventing the occurrence of low temperature burns. Can do. The concavo-convex structure composed of the annular ridges 13a and 17a on both sides of the hot water bottle main body and the concave portions 13 and 17 in the present invention is provided so as to penetrate the disc-shaped hot water bottle main body at the central portion, and also from the annular ridge lines on both sides in the radial direction. Contributes to improving the overall strength of the disc-shaped hot water bottle body that is most affected by the pressure change caused by the temperature drop, as well as the concavo-convex structure composed of the concave ridges 16a, 16a 'and the ridges 16b, 16b'. It works more effectively by prevention.
