Description

[Technical field]

[0001] The present invention relates to a hot water bottle used for keeping warm. [Background technology]

[0002] For example, there is a hot water bottle that is oval-shaped when placed on a bed. An oval-shaped hot water bottle has a hot water inlet near one end in the length direction. Hot water is poured into the hot water bottle from this inlet. When discharging hot water from the inlet, the user lifts the hot water bottle and points the inlet downward so that the hot water flows out from the inlet facing downward. When a user wants to drain hot water in this way, the user must lift the hot water bottle and stand it up or turn it over to allow the hot water to drain from the inlet, which is time-consuming.

[0003] The hot water bottle described in Patent Document 1 comprises a hot water bottle body and a cap that is attached to the hot water inlet of the hot water bottle body, and the entire bottom surface of the body is formed flat to allow the hot water bottle body to stand on its own. When the hot water bottle body is left standing and the cap is removed from the hot water inlet formed near the bottom end of the hot water bottle body, hot water will drain from the inlet even if the user leaves the hot water bottle in this state. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2015-085130 A Summary of the Invention [Problem to be solved by the invention]

[0005] In the hot water bottle of Patent Document 1, if the cap is removed from the inlet and the body of the hot water bottle is allowed to stand on its own, the hot water will naturally drain from the inlet, so the user does not have to go through any effort. However, in order to stabilize the body of the hot water bottle, as shown in FIG. 1 of Patent Document 1, the entire flat bottom surface of the hot water bottle body is made wide, and the lower part of the hot water bottle is made cylindrical to match the shape of the flat bottom. Therefore, even if the hot water bottle is allowed to stand on its own and the hot water is allowed to drain from the inlet, not all of the hot water is drained, and much of the hot water remains inside the lower part of the hot water bottle, which has a cylindrical shape. In order to drain this remaining hot water from the body of the hot water bottle, the user still needs to lift the hot water bottle and point the inlet downward to drain the hot water.

[0006] To solve the above-mentioned problems, the present invention aims to make it possible to more quickly drain hot water from inside a hot water bottle by making the hot water bottle self-supporting, while also extremely reducing the amount of hot water remaining inside the hot water bottle. [Means for solving the problem]

[0007] The hot water bottle of the present invention is a hot water bottle comprising a thick, oval-shaped body with a hollow interior, and a flat surface formed at one end of the body in the longitudinal direction, extending in a width direction perpendicular to the longitudinal direction and in the thickness direction of the body, the one end having the flat surface located in the centre in the width direction, inclined surfaces formed on both sides of the flat surface in the width direction and connected to the flat surface, and legs provided on the inclined surface that are flush with the flat surface and extend parallel to the flat surface in the width direction, the body stands on its own with the one end as its bottom and the flat surface and the legs in planar contact with a placing surface, and when the body is in the self-supporting state, one side portion which is planar and extends in the longitudinal and width directions has a pouring spout formed in the centre in the width direction at the end which is on the side of the one end in the longitudinal direction, and the inclined surface when the body is in the self-supporting state has an upward slope that connects from the flat surface at the one end, and forms the edge of the bottom side of the one side portion. Effect of the Invention

[0008] According to the hot water bottle of the present invention, by making the hot water bottle self-supporting, hot water can be discharged from inside the hot water bottle more quickly and the amount of hot water remaining inside the hot water bottle can be greatly reduced.

Fig. 7 is a bottom view showing a hot water bottle according to one embodiment of the present invention as viewed from below.

[0011] Hot water bottle 10 according to one embodiment of the present invention comprises hot water bottle body 11, cap 13 which is removably attached to hot water inlet 12, and funnel 14. Hot water bottle body 11 is made of polyethylene, for example, and in the case of polyethylene, it is formed as a single piece by blow molding or the like. Hot water bottle 10 is in the shape of a thick oval. Note that it is not intended that hot water bottle 10 be limited to being made of polyethylene.

[0012] Hot water bottle body 11 (hereinafter referred to as body 11) has a hollow section for storing hot water inside, and further has a handle 22 formed at what would be the upper end of body 11 in Figure 1. Hot water bottle body 11 has thickness at peripheral edge 101, and is oval-shaped, including handle 22 formed at the upper end.

[0013] The main body 11 is formed so that its size in the length direction and width direction is larger than its size in the thickness direction. The width direction is a direction perpendicular to the length direction.

[0014] The front part 211 of the main body 11 is flat (or may be curved) forming a part of an oval shape, and is formed with a vertical rib 24 and multiple horizontal ribs 25. The back part 212 of the main body 11, which is opposite the front part 211, is flat (or may be curved) forming a part of an oval shape, and is formed with multiple horizontal ribs 26. The vertical rib 24 and each horizontal rib 25, 26 improve the strength of the main body 11, and suppress deformation of the main body 11 due to thermal expansion caused by pouring molten metal into the main body 11, etc.

[0015] The main body 11 has one end 11A which forms the bottom of the main body 11. One end 11A, which is the end in the length direction of the main body 11, is formed with a flat surface 21C which extends in the width direction and thickness direction.

[0016] One end 11A is composed of a flat surface 21C arranged in the center in the width direction, inclined surfaces 21D formed on both sides of the flat surface 21C in the width direction and connected to the flat surface 21C, and legs 23 provided on each of the inclined surfaces 21D, flush with the flat surface 21C and extending parallel to the flat surface 21C in the width direction. The main body 11 stands on its own with the flat surface 21C and the legs 23 in planar contact with the placement surface with the one end 11A as the bottom.

[0017] When the main body 11 is in a self-supporting state, one side surface portion that is flat and extends in the length direction and width direction is the front surface portion 211 , and the other side surface portion that is the reverse side is the rear surface portion 212 .

[0018] Furthermore, in the front portion 211, a recess 21A recessed below the surfaces of the vertical ribs 24 and the horizontal ribs 25 is formed in the center in the width direction at the end of the front portion 211 on the one end 11A side (near the lower end in FIG. 2). A pouring spout 12 is formed in this recess 21A. That is, in the front portion 211, a pouring spout 12 is formed in the center in the width direction at the end of the front portion 211 on the one end 11A side (the lower end in FIG. 2). The pouring spout 12 has an opening that connects to a hollow portion within the main body 11.

[0019] When main body 11 is freestanding, inclined surface 21D slopes upward from flat surface 21C at one end 11A, and forms the edge of the bottom side (one end 11A side) of front portion 211. That is, as shown in Figure 2, inclined surface 21D slopes downward from a position on the side edge of front portion 211 that is above the lower part of pouring spout 12, to a position near the lower part of pouring spout 12, when viewed from the front of hot water bottle 10.

[0020] As a result, when the main body 11 is in a self-supporting state, as shown generally in Figure 8, the main body 11 has a shape in which, in the internal hollow portion 115, the inner wall portion 115A forming the back side of the inclined surface 21D slopes downward toward the opening connected to the pouring spout 12.

[0021] Further, a recess 21B is formed in the rear portion 212 of the main body 11, which is recessed below the surface of the transverse rib 26. Inside the recess 21B, a cylindrical protrusion 28 is provided at the bottom portion of the recess 21B. A plurality of notches 28A are formed in the outer circumferential surface of the cylindrical protrusion 28. Furthermore, the diameter of the cylindrical protrusion 28 is set to a size such that the inner wall of the hole 141 of the funnel 14 fits into the outer circumferential surface of the cylindrical protrusion 28 at a portion not having the notches 28A.

[0022] The recess 21B formed in the back surface portion 212 is circular and has a diameter larger than the maximum outer diameter of the funnel 14. A notch 27 is formed in a part of the circular diameter portion of the recess 21B, which expands the shape of the recess 21B from the above diameter toward the outside of the above diameter.

[0023] Funnel 14 is attached to main body 11 by fitting the inner wall of hole 141 of funnel 14 to the outer peripheral surface of cylindrical protrusion 28, and funnel 14 is removed from main body 11 by releasing the fitting of the inner wall of hole 141 of funnel 14 from the outer peripheral surface of cylindrical protrusion 28 and separating funnel 14 from cylindrical protrusion 28. In this way, funnel 14 is detachable from main body 11 at recess 21B.

[0024] The thickness of the main body 11, including the vertical ribs 24, the horizontal ribs 25 and the horizontal ribs 26, is approximately constant except for the areas of the recesses 21A and 21B.

[0025] When the main body 11 is in a self-supporting state, the side edges in the width direction of the front part 211 are formed in an arc shape that forms part of an oval shape. That is, the side edges on both sides in the width direction of the front part 211 of the main body 11 draw an arc such that the width of the main body 11 narrows at the upper and lower parts in FIG. 2 and the like, and as shown in FIG. 9 and FIG. 10, the upper part is connected to both ends of the handle 22, the lower part is connected to the inclined surface 21D, and also connected to the side edges of the legs 23. FIG. 9 is a perspective view showing one end part 11A of the main body 11 of the hot water bottle 10 as viewed from below, with the one end part 11A highlighted by coloring. FIG. 10 is a perspective view showing one end part 11A of the main body 11 of the hot water bottle 10 as viewed from above with the one end part 11A on the upper side, with the one end part 11A highlighted by coloring.

[0026] Each of the pair of legs 23 extends at one end 11A, as described above, in the width direction parallel to the flat surface 21C and is flush with the flat surface 21C, and further has an upward incline that connects to the arc-shaped side edge portion of the front portion 211, and the side edge portion 23B of the leg portion 23 forms the above-mentioned arc shape integrally with the side edge portion 211B of the front portion 211 (part of the peripheral portion 101).

[0027] The leg portions 23 are thinner than the inclined surface 21D in the thickness direction, and are provided so as to protrude outward from the surface of the inclined surface 21D.

[0028] The width of main body 11 is widest near the center of main body 11 in the longitudinal direction and becomes narrower in the longitudinal direction toward handle 22 and flat surface 21C. When viewed from the front of hot water bottle 10, the width of main body 11 is formed so as to become narrower at the lower part of main body 11 from the side edge of main body 11 toward pouring spout 12.

[0029] A pair of legs 23 provided on both sides of the lower end of the main body 11 are located on both outsides of the pouring spout 12 in the width direction, and are located on both outsides of the portion of the main body 11 whose width is particularly narrow as described above.

[0030] 11 shows a schematic diagram of the flat surface 21C and the bottom surface 23A of each leg 23 at one end 11A of the main body 11. The bottom surface 23A of each leg 23 is flush with the flat surface 21C of the main body 11 and extends in the width direction of the main body 11 to a position where the side edge 23B of the leg 23 forms the above-mentioned arc shape integrally with the side edge 211B of the front part 211. At the same time, the flat surface 21C has a size close to the thickness of the main body 11 in the thickness direction. Therefore, when the flat surface 21C of the main body 11 and the bottom surface 23A of each leg 23 are in surface contact with the placement surface facing downward, the hot water bottle main body 11 is supported stably on the placement surface by the surface contact of the flat surface 21C and the bottom surface 23A of each leg 23 with the placement surface, and the hot water bottle main body 11 is unlikely to tip over in either the front-rear or sideways direction.

[0031] Furthermore, even if the bottom surface 23A of each leg 23 protrudes slightly from the flat surface 21C of the main body 11, as long as the surface-to-surface contact of the flat surface 21C and the bottom surfaces 23A of each leg 23 with the support surface is not impeded and the hot water bottle 10 can stand on its own, the slight protrusion is considered to be included in the flush surface.

[0032] As described above, the inclined surface 21D at one end 11A of the main body 11 has a slope that slopes downward from the side edge of the front part 211, which is higher than the lower part of the pouring spout 12, toward a position near the lower part of the pouring spout 12 when viewed from the front of the hot water bottle 10 (FIG. 2). Therefore, when the main body 11 is freestanding, the inner wall part 115A forming the back side of the inclined surface 21D in the internal hollow part 115 slopes downward toward the opening that leads to the pouring spout 12. For this reason, when the hot water bottle 10 containing hot water is stood upright on a placement surface after the cap 13 is removed from the pouring spout 12, as shown in FIG. 8, the hot water in the main body 11 generates a water flow on both sides of the pouring spout 12 due to the guidance of the inclined inner wall part 115A and gravity, and the hot water is guided along the slope to the pouring spout 12. This allows the hot water to be quickly drained from inside the hot water bottle 11.

[0033] For example, in the case of the hot water bottle shown in JP 2015-085130 A (Patent Document 1), the lower part of the main body is formed into a cylindrical shape, and the inner walls of the main body on both sides of the pouring spout are flat surfaces parallel to the surface on which it is placed, so that inside the main body on both sides of the pouring spout, hot water is not actively guided to the pouring spout, as is the case with hot water bottle 10 of this embodiment. For this reason, hot water bottle 10 of this embodiment can drain hot water from the inside more quickly than conventional hot water bottles.

[0034] In addition, when viewed from the front of hot water bottle 10, the width of main body 11 at the lower part of main body 11 is formed so that it narrows as it approaches inlet 12 from the side edge of main body 11.Therefore, the capacity of hot water stored in the areas on both sides of inlet 12 within main body 11 is less than in the case of the hot water bottle shown in JP 2015-085130 A (Patent Document 1), and the amount of hot water remaining in the lower part of main body 11 is extremely small.

[0035] Therefore, with hot water bottle 10 according to this embodiment, by making hot water bottle 10 self-supporting, hot water can be drained from inside hot water bottle 10 even more quickly, and the amount of hot water remaining inside hot water bottle 10 can be greatly reduced. Furthermore, being able to greatly reduce the amount of hot water remaining inside hot water bottle 10 in this way contributes to eliminating or minimizing the work required for the user to drain the remaining hot water from main body 11 by lifting hot water bottle 10 and pointing inlet 12 downward to drain the hot water.

[0036] Incidentally, even when hot water bottle 10 is shaped in this way so as to promote the drainage of hot water and reduce the amount of hot water remaining at the bottom of main body 11 by providing inclined surface 21D at one end 11A of main body 11 as described above, when hot water bottle 10 is made to stand on its own, not only flat surface 21C but also legs 23 come into surface contact with the base surface to support hot water bottle 10 on the base surface. For this reason, legs 23 contribute to achieving both the above-mentioned shape of inclined surface 21D at one end 11A of main body 1 which promotes the drainage of hot water and reduces the amount of hot water remaining at the bottom of main body 11, and the ability to make hot water bottle 10 stand stably.

[0037] When pouring hot water into hot water bottle 10, as shown in Figure 12, hot water bottle 10 is placed on its side, cap 13 is removed from spout 12 of body 11, inner tube 14B of funnel 14 is inserted into spout 12, and hot water is poured into funnel 14 and into body 11. At this time, outer tube 14C of funnel 14 is positioned on the outside of spout 12. In other words, the protruding spout 12 is sandwiched between inner tube 14B and outer tube 14C of funnel 14. After using funnel 14 to pour hot water into hot water bottle 10 through spout 12, funnel 14 is attached to body 11 by fitting its hole 14A (the inner diameter of inner tube 14B) into the outer diameter part of cylindrical protrusion 28 (see Figure 4 and Figure 13 below).

[0038] Fig. 13(A) is a cross-sectional view showing the recess 21B on the rear side of the main body 11 and the funnel 14 housed in the recess 21B, and Fig. 13(B) is a front view thereof. Fig. 14(A) is a perspective view showing the funnel 14 fitted into the cylindrical protrusion 28 of the recess 21B on the rear side of the main body 11, and Fig. 14(B) is a perspective view showing the funnel 14 removed. In Figs. 14(A) and 14(B), the outer tube 14C is omitted in order to clarify the relationship between the cylindrical protrusion 28 and the inner tube 14B of the funnel 14.

[0039] As is clear from FIGS. 13(A) and 13(B) and 14(A) and 14(B), hole 14A of inner tube 14B of funnel 14 is detachably fitted into cylindrical protrusion 28 on the bottom surface of recess 21B.

[0040] When removing the inner tube 14B of the funnel 14 from the cylindrical protrusion 28 of the recess 21B, a finger is inserted into a depression 27 provided on the lower inner periphery of the recess 21B, and the funnel 14 is pulled out from the recess 21B.

[0041] The outer diameter of the cylindrical protrusion 28 may change due to thermal expansion. When the outer diameter of the cylindrical protrusion 28 increases due to the thermal expansion, the deformation of the cylindrical protrusion 28 due to the increase in the outer diameter is absorbed by the multiple (four in this embodiment) notches 28A provided on the outer peripheral surface of the cylindrical protrusion 28. This suppresses the amount of change in the outer diameter of the cylindrical protrusion 28 due to the increase, so that even if the outer diameter of the cylindrical protrusion 28 increases due to thermal expansion when hot water is poured into the hot water bottle 10 using the funnel 14 from the pouring spout 12, it becomes easier to fit the brother 14A of the funnel 14 that has been used into the outer diameter portion of the cylindrical protrusion 28. Therefore, the funnel 14 can be easily attached to the main body 11 regardless of the thermal expansion of the cylindrical protrusion 28.

[0042] Incidentally, the configuration of the embodiment described above with reference to FIGS. 1 to 14 is merely one example of the present invention, and is not intended to limit the present invention to this configuration. [Explanation of symbols]
