Description

  The present invention relates to a hot water bottle whose wall portion has a two-layer structure.

The wall portion of the hot water bottle is usually formed of a single layer structure, and the wall portion is formed of one material such as plastic or metal.
However, some hot water bottles have a two-layer structure in order to increase their added value. For example, Patent Document 1 below discloses a “plastic hot water bottle” configured by such a two-layer structure.

  The wall portion of the “plastic hot water bottle” in Patent Document 1 is integrally formed as a laminated structure of a non-foamed plastic layer and a foamed plastic layer, and is configured in close contact with each other.

  Furthermore, in the case where the foamed plastic layer is located outside the two-layer structure, even if only the shape of the foamed plastic layer is changed, the foamed plastic layer is generally low in shape retention due to its material characteristics. It must be said that it is difficult to maintain the appearance of the hot water bottle only by this foamed plastic layer.

Therefore, in order to manufacture hot water bottles having different external shapes, existing foamed plastic layers or non-foamed plastic layers cannot be diverted, and only the above-mentioned foamed plastic layers located outside the wall portion of the two-layer structure are used. However, it is necessary to remanufacture the mold including the non-foamed plastic layer.
That is, the same labor and cost as manufacturing a hot water bottle are required.

  As a result, when trying to manufacture hot water bottles having different forms and materials, the cost increases, variations in design and characteristics are limited, and there is a problem that diversifying customer demands cannot be satisfied.

Japanese Utility Model Publication No. 60-155518

  Therefore, the present invention has an object to provide a hot water bottle having a two-layer structure that can be easily manufactured in various forms and materials and has a variety of appearance and characteristics.

  The hot water bottle in the present invention has a two-layer structure of an inner wall portion and an outer wall portion, and the inner wall portion is made of synthetic resin, and the outer wall portion is made of metal. It is characterized by.

  Although the said synthetic resin material will not be specifically limited if it is excellent in intensity | strength, For example, a high density polyethylene can be mentioned.

  The metal material includes, for example, stainless steel, aluminum, copper, or iron, a metal alloy such as a super dimmer steel plate, and those obtained by plating these metals.

The hot water bottle in the present invention is configured to have a smooth surface on the surface of the outer wall,
A decorative medium can be attached to the smooth surface.

  The decoration medium includes a picture, a pattern, a symbol, a character, a drawing, and a combination of these, or a simple coloring medium, and indicates a medium that can improve designability and visibility.

  The smooth surface is a smooth surface in which a plurality of irregularities (ribs) are not formed on the surface, and includes not only a flat surface but also a surface having a smooth curvature.

  The means for attaching the decoration medium is not particularly limited. For example, a means for applying decoration by pressing a sheet on which a plurality of decoration media are drawn against the surface of the outer wall portion is preferable.

  Most of the outer wall portions of the hot water bottle have a curved shape in cross section, and when the outer wall portion is made of metal that is difficult to attach a decorative medium, the surface of the outer wall portion is directly decorated with, for example, a pen. By applying the above-described means for attaching a decoration medium by printing, the surface of the outer wall portion can be easily and nicely decorated.

  Further, by attaching the decoration medium to the smooth surface, the decoration medium can be accurately and nicely attached.

  In addition, in the case of a small portable hot water bottle, there is no need to form irregularities (ribs) for preventing deformation of the shape on the surface of the outer wall portion, so that it is easy to ensure a smooth surface on the surface of the outer wall portion. It can be said that the hot water bottle is particularly suitable for attaching a decoration medium.

  In the hot water bottle of the present invention, the inner wall portion is formed in a hollow shape having an internal space, and the outer wall portion is attached to the upper side of the inner wall portion and the lower side of the inner wall portion. It is characterized by being divided into two members with the lower outer wall member.

  With the above configuration, each of the upper outer wall member and the lower outer wall member can be configured in a form that can be easily molded by a mold or the like, for example.

  Even when the inner wall portion and the outer wall portion are integrated, the upper outer wall member and the lower outer wall member can be easily attached to the inner wall portion from the upper and lower sides.

  The hot water bottle of the present invention preferably comprises a hollow portion between the outer wall portion and the inner wall portion.

  With this configuration, an air heat insulating layer can be secured between the outer wall portion and the inner wall portion, so that low temperature burns can be prevented. Furthermore, the hot water bottle can be used for a long time by reducing the rate of decrease in the hot water temperature.

  Furthermore, since the hot water bottle of the present invention has a two-layer structure, it has a unique effect of the two-layer structure, for example, it can be configured to prevent water leakage as compared with a single-layer hot water bottle.

The hot water bottle of the present invention can exhibit the above-described unique effects due to the two-layer structure, and the outer wall portion located outside the two-layer structure with which the human body comes in contact with the characteristics such as thermal conductivity depending on the type. Therefore, the difference in the characteristics can be remarkably marked only by changing the type of the metal material of the outer wall portion.
Therefore, various hot water bottles can be efficiently prepared with a minimum of labor and cost.

  Moreover, by attaching a decoration medium to the surface of the outer wall portion, a hot water bottle that is further rich in variations and excellent in design can be easily configured without the need to remake the configuration of the outer wall portion or the inner wall portion, for example.

Moreover, since the hot water bottle of the present invention has an inner wall portion made of synthetic resin inside the two-layer structure, the outer wall portion can be made thin from the viewpoint of strength and the like. For this reason, even if the outer wall portion is made of metal, the workability and formability of the outer wall portion can be remarkably improved as compared with a normal hot water bottle having a single-layer structure with a metal wall portion.
Therefore, various hot water bottles rich in variations can be easily prepared.

  In addition, rust prevention can be improved by constructing the inner wall part where hot water is present in the internal space with a synthetic resin material. The effect that it can form can also be show | played.

An embodiment of the present invention will be described below with reference to the drawings.

The outer wall portion 14 is made of stainless steel, and the inner wall portion 15 is made of synthetic resin. A hollow portion B is formed between the outer wall portion 14 and the inner wall portion 15 of the wall portion 12 of the hot water bottle 11. In the present embodiment, the hollow portion B is configured only at the upper surface side portion and the bottom surface side portion of the hot water bottle 11 between the outer wall portion 14 and the inner wall portion 15. The hollow portion B is filled with air to form an air layer.

The inner wall portion 15 is formed in a hollow shape of the inner space A as shown in FIG. 3 by blow molding.
FIG. 3 is an external view of the inner wall portion 15 of the hot water bottle 11. More specifically, the inner wall portion 15 is shown as a separate body from the outer wall portion 14.

The inner wall portion 15 is configured as a hot water bottle main body member 15X having a function and a form necessary for using it alone as a hot water bottle. The pouring port part 13 on the upper surface of the inner wall part 15 is formed in a form protruding outward. Although not shown in FIG. 3, the pouring port portion 13 is configured so that a plug body 17 for closing the pouring port can be attached.
That is, a female screw portion 13 b that can be screwed with a male screw portion 17 b provided on the plug body 17 is integrally formed on the outer periphery of the pouring port portion 13. Further, an inner wall small protrusion 15a protruding outward along the outer periphery thereof is integrally formed at an intermediate portion in the vertical direction (thickness direction) of the inner wall 15.

On the other hand, the outer wall portion 14 includes two members, an upper outer wall member 18 and a lower outer wall member 19.
The upper surface of the upper outer wall member 18 and the lower surface of the lower outer wall member 19 are formed in an uneven shape for preventing deformation or improving design.

  Specifically, the upper surface of the upper outer wall member 18 is configured in a bowl shape that is gently bulged, and further, the surface thereof is configured in a wavy form. On the other hand, the bottom surface of the lower outer wall member 19 is configured to be flat so that it can be installed on an installation stand or the like, and a plurality of concave portions 19c are arranged in parallel at predetermined intervals.

  In addition, although the hot water bottle in 1st embodiment has attached | subjected the code | symbol 11, below, when emphasizing that it is the hot water bottle provided with the said outer wall part 14 comprised with the form mentioned above and a material, code | symbol 11A A description will be given with.

  An opening 18b is formed in a portion corresponding to the pouring port 13 in the outer wall 14. The opening portion 18b is opened with a diameter that is slightly larger than the pouring port portion 13 protruding in the inner wall portion 15, and the pouring port portion 13 is inserted from the inner side (lower side) to the outer side (upper side) of the outer wall portion 14. It is configured to be possible.

In addition, an outer wall small protrusion 19 a protruding outward is formed at the upper peripheral edge of the lower outer wall member 19.
The outer wall small protrusion 19a protrudes with substantially the same amount of protrusion as the inner wall small protrusion 15a.

  An outer wall recess 18a that allows the outer wall small protrusion 19a and the inner wall small protrusion 15a to be fitted together is formed at the lower peripheral edge of the upper outer wall member 18.

  The hot water bottle 11 having the above-described configuration can be integrally formed by attaching the outer wall portion 14 from the outside to the inner wall portion 15 at the time of manufacture.

At this time, since the outer wall small protrusion 19a and the inner wall small protrusion 15a are integrally fitted in the outer wall recess 18a, the upper outer wall member 18, the lower outer wall member 19, and the inner wall 15 Can be integrated.
A plurality of ribs 22 are provided upright in the hollow portion B between the inner wall portion 15 and the lower outer wall member 19.

  Furthermore, when the outer wall portion 14 and the inner wall portion 15 are integrated, the pouring port portion 13 is inserted into the opening portion 18b of the outer wall portion 14, and the mouth portion of the opening portion 18b has a hollow portion. In order to ensure the waterproofness of B, a packing 23 formed of natural rubber or the like is attached.

  The hot water bottle 11 configured as described above can exhibit various actions and effects as described below.

For example, when manufacturing a hot water bottle 11B having a different appearance shape and characteristics from the hot water bottle 11A described above, as shown in FIG. 4, a main body member 15X (inner wall portion 15) for use in the configuration of the hot water bottle 11A is diverted. be able to. What is necessary is just to mount | wear the main body member 15X with the outer wall part 24 different from the said outer wall part 14 used for the structure of the hot water bottle 11A.
FIG. 4 is an explanatory view showing a state of one process at the time of manufacturing the hot water bottle 11B. The hot water bottle denoted by reference numeral 11B is a hot water bottle in the present embodiment having a design and characteristics different from those of the hot water bottle 11A described above. Show.

The outer wall portion 24 of the hot water bottle 11B is made of copper, and the lower outer wall portion 29 has the same form as the lower outer wall member 19 used in the hot water bottle 11A, but the upper outer wall member 28 is formed of the hot water bottle 11A. The upper outer wall member 18 used in is configured in a different form.
More specifically, the upper outer wall member 28 has a flat upper surface, and a plurality of recesses 28a arranged in parallel on the flat upper surface.

  Thus, when manufacturing the hot water bottle 11B having different designs and characteristics, only the outer wall portion may be changed to a different design, characteristic shape and material at the time of manufacture, and the inner wall portion 15 is made of the hot water bottle 11A. A main body member 12A having the same form and material as used can be used.

Thus, since the outer wall part 24 made of a different form and material from the above may be attached to the hot water bottle main body member 15X (inner wall part 15) constituting the main body part of the hot water bottle, The hot water bottle 11B having different appearance design and characteristics can be easily manufactured as shown in FIGS.
5 shows an external view of the hot water bottle 11B of the present embodiment, and FIG. 6 shows a cross-sectional view of the hot water bottle 11B of the present embodiment.

  Therefore, when changing the design of a conventional hot water bottle to one having a different form or characteristic, it is necessary to newly design all the members including the inner wall portion 15 and to re-manufacture them. The hot water bottle 11 according to the present embodiment can easily configure the hot water bottle 11B having different designs and characteristics at low cost.

  In particular, in the hot water bottle 11 according to this embodiment, the outer wall portions 14 and 24 are made of metal, and the inner wall portion 15 is made of a synthetic resin. By the way, the characteristics of heat conductivity, price, strength, weight and the like greatly differ depending on the material among the metals. By configuring the outer wall portion 14 that is in contact with the human body and that determines the appearance of the outer appearance with such a metal material, the difference in characteristics unique to the metal material can be effectively reduced for the user. It becomes possible to realize.

  In the present embodiment, an example in which the outer wall portion 14 made of stainless steel is changed to the outer wall portion 24 made of copper has been described. However, when the user uses the hot water bottle 11A and the hot water bottle 11B, for example, the outer wall portion is made of synthetic resin. Compared to the case of a hot water bottle whose inner wall is made of metal, this difference in thermal conductivity can be noticed significantly.

  Therefore, just by changing the outer wall, the difference in characteristics between multiple hot water bottles can be made remarkable, so there are a wide variety of variations according to the application, usage environment, and user demands, without labor and cost. You can make a hot water bottle.

  Further, as described above, the hot water bottle 11 in the present embodiment is configured such that the inner wall portion 15 itself has a function and performance as a hot water bottle main body, and the outer side of such an inner wall portion 15 (hot water bottle main body member 15X). To the outer wall 14 (, 24). For this reason, the outer wall part 14 (, 24) can be made into a structure excellent in economic efficiency, for example, by forming it thinner than the wall part 12 in the case of a single layer structure.

  Therefore, even if the outer wall portion 14 (, 24) is made of metal, the workability and formability can be remarkably improved as compared to a metal single layer hot water bottle, and the design etc. are changed. It becomes possible to manufacture more easily.

  Moreover, since the inner wall part 15 is comprised with the synthetic resin, the rust prevention property of the inner wall part 15 which contacts hot water can be improved. Furthermore, since synthetic resin is basically superior in elasticity compared to metal, it is difficult to plastically deform and there is an advantage that it is not necessary to provide ribs in the internal space A in the inner wall portion 15.

  In addition, the hot water bottle 11 in the present embodiment can exhibit the following actions and effects.

  In addition, since the hot water bottle 11 of the present embodiment has a two-layer structure of the outer wall portion 14 (, 24) and the inner wall portion 15, it can improve the waterproofness as compared with the hot water bottle having a single-layer structure and is durable. Can also be improved.

  Furthermore, the hot water bottle 11 of the present embodiment has a hollow portion B between the outer wall portion 14 and the inner wall portion 15. The heat insulation action by the air layer filled in the hollow portion B can prevent low-temperature burns, and can also provide the advantage that the temperature gradient of the hot water stored in the internal space A can be reduced. it can.

  Below, the hot water bottle in other embodiment is demonstrated.

  However, in the configuration of the hot water bottle described below, the same configuration as the hot water bottle in the first embodiment described above is denoted by the same reference numeral, and the description thereof is omitted.

(Second embodiment)
The hot water bottle 21 in the second embodiment is small in size so that it can be carried in a pocket or the like. Moreover, although the hot water bottle 21 of this embodiment is also a two-layer structure, the outer wall part 34 is a product made from tinplate.

  Furthermore, since the hot water bottle 21 is small in size, the outer wall portion 34 and the inner wall portion 35 do not need to take into account compressive deformation due to the internal atmospheric pressure, and the surface of the outer wall portion 34 of the hot water bottle 21 is generally smooth. It is configured with a smooth surface, and is not configured with irregularities (ribs) such as a plurality of recesses 19c, 28a like the outer wall portion 14 of the hot water bottle 11 of the first embodiment.

  For example, a decoration medium 33 such as a floral pattern as shown in FIG. 7 is printed on the surface of the hot water bottle 21, particularly the upper side wall portion 38. By attaching such a decoration medium 33, it is possible to configure the appearance with excellent design and decoration.

  Accordingly, it is possible to provide a plurality of hot water bottles 21 having various variations according to customer preferences.

  In particular, by applying the decorative medium 33 described above to the surface of the outer wall portion 34 by printing, even if the surface has a curved shape in sectional view and is difficult to be colored, the outer wall portion 34 is made of, for example, a large number in advance. If you have prepared a sheet (not shown) with a pattern on it, you can create various hot water bottles with excellent decoration by simply pasting the pattern in this sheet on the surface of the outer wall 34 of the hot water bottle 21 in sequence. Can be produced in large quantities.

  Furthermore, if the hot water bottle 21 is small as in the present embodiment, there is no need to form irregularities (ribs) on the surface, and a smooth surface having a smooth surface shape can be decorated. It is easy to print and is suitable for decorating.

  Further, the decoration medium 33 is not limited to the floral pattern as described above, and may be other patterns, and may be a character such as a human being or an animal, a picture, a character, or a symbol.

Furthermore, the hot water bottle in the present invention is not limited to the hot water bottles 11 and 21 of the above-described embodiment.
For example, in the above description, the embodiment in which only the shape of the upper outer wall members 18 and 38 is changed among the outer wall portions 14 and 34 has been described. Of course, any one of the upper outer wall members 18 and 38 and the lower outer wall members 19 and 39 is used. Alternatively, the shape and characteristics of only the lower outer wall members 19 and 39 can be changed.

  Further, for example, as described above, the hot water bottles 11 and 21 in the present invention are configured such that the inner wall portions 15 and 35 and the lower outer wall members 19 and 39 are fitted and integrated by the upper outer wall members 18 and 38. However, the present invention is not limited to this, and may be integrally formed by other fixing means using screws or pins. Furthermore, you may comprise the outer wall parts 14 and 34 with respect to the inner wall parts 15 and 35 so that attachment or detachment is possible with a buckle.
