Description

  The present invention relates to a double bottle.

  A bottle called a double bottle or a thermos bottle has a heat insulating effect by heat insulation, has a low risk of burns, and is a widely used container.

  Early thermos bottles have two bottles: an inner bottle and an outer bottle. The outer bottle is made of a stainless material, the inner bottle is made of glass, and a reflective layer (for example, silver or mercury) is laid on the surface, and a heat retaining effect is obtained by reflecting heat.

  A recent thermos has a double structure and includes an inner wall, an outer wall, and a heat insulating space interposed between the inner wall and the outer wall. In many cases, stainless steel material is adopted for the inner wall and the outer wall, and air is prevented from becoming a medium for transferring heat by making the heat insulating space in a vacuum state.

  Furthermore, the thermos described in Patent Document 1 is a double cup body made of a high molecular polymer (for example, plastic), and a space between the inner wall and the outer wall of the cup body becomes a heat insulating space. The inner wall and the outer wall are made of the same material, and both are melted and integrated by a high frequency equipment.

Taiwan Utility Model No. M405221

  However, in the prior art described above, these thermos are usually monochromatic. Therefore, how to improve the monotonous color of the double bottle is a problem that the present invention aims to solve.

  Therefore, the present inventor considered that the above-described drawbacks can be improved, and as a result of intensive studies, the present inventor has arrived at a proposal of the present invention that effectively improves the above-described problems with a rational design.

  The present invention has been made to solve the above-described problems of the prior art. That is, the object of the present invention is to provide a double bottle. That is, a combination structure is adopted, which has effects such as multicolor and heat retention, and improves the disadvantage that the conventional double bottle is monotonous.

In order to solve the above-mentioned problems and achieve the purpose, the double bottle according to the present invention is:
An outer bin having an open end, an inner bottle having an entrance and exiting from the open end, and a space formed by separating the inner bin and the outer bin; an inner bin and an outer bin; And a water leakage prevention ring for sealing a space formed by being separated from each other.

  In the double bottle of the present invention, the inner bottle and the outer bottle are transparent. The water leakage prevention ring is an independent ring body between the inner bottle and the outer bottle, and may be a ring body designed to be integrated with any one of the inner bottle and the outer bottle. The water leakage prevention ring is a circumferential surface having a thickness of 0.5 to 30 mm.

  The double bottle described above further includes an air vent structure and an engagement structure. The air vent structure is provided between the inner bottle and the outer bottle, which is arbitrarily selected from a hole, a groove, or a concave hole, and is formed in any one of the inner bottle and the outer bottle. The engagement structure is provided in a recess provided in any one of the inner bottle, the outer bottle, and the water leakage prevention ring, and provided in any one of the inner bottle, the outer bottle, and the water leakage prevention ring. And a convex portion to be inserted.

  In this way, since the outer bottle is transparent, the color of the inner bottle can be visually checked, and it is possible to improve the disadvantage that the conventional bottle is monotonous with the effects of multiple colors and heat retention. In addition, the outer bottle covers the inner bottle to reduce the volume of the space separated by the inner bottle and the outer bottle, the air vent structure provides a path for releasing the atmospheric pressure, and the engagement structure connects the inner bottle and the outer bottle. This prevents the inner bottle and the outer bottle from separating.

  Preferred embodiments of the present invention will be described with reference to the accompanying drawings. The embodiment described below does not limit the contents of the present invention described in the claims of the utility model registration. In addition, all the configurations described below are not necessarily essential requirements of the present invention.

<First Embodiment>
Hereinafter, specific embodiments of the present invention will be described with reference to the accompanying drawings. 1 and 2 are specific structures of the bottle 10 according to the first embodiment. The bottle 10 includes a lid 20 shown by a broken line in FIG. 1, an outer bottle 30, and an inner bottle 40. The lid body 20 has a single inner thread (not shown).

  The outer bottle 30 is a transparent circular container, has an open end 32 and a bottom 34, and is provided with two concave portions 36 at positions adjacent to the open end 32 of the outer bottle 30. A line pattern for preventing slippage is formed on the outside of the outer bottle 30 (not shown). In the present embodiment, the bottom 34 of the outer bottle 30 is sealed. In some embodiments, the bottom 34 of the outer bottle 30 is open.

  In addition, the above-mentioned recessed part 36 comes to penetrate the long hole of the wall surface of the outer bottle 30 in diameter. Needless to say, it is also within the scope of the present embodiment that the recess 36 is a long or arcuate groove and is formed on the inner wall of the outer bottle 30.

  The inner bottle 40 has a cylindrical shape and includes an inlet / outlet 42 and a blocking portion 44, and liquid is injected into the inner bottle 40 from the inlet / outlet 42 or flows out of the inlet / outlet 42. The inner bottle 40 has a water leakage prevention ring 48 and a coupling stage 46. The above-described water leakage prevention ring 48 protrudes from a portion adjacent to the entrance / exit 42 on the outside of the inner bottle 40 and has a diameter corresponding to the two protrusions 41 formed outside the water leakage prevention ring 48.

  In the present embodiment, the shape of the convex portion 41 described above substantially coincides with the rectangular block of the concave portion 36. In a certain embodiment, the convex part 41 is a bowl-shaped square block.

  The above-described coupling stage 46 indicates one stage of external thread and is screwed into the internal thread of the lid 20 and can be removed.

  When the inner bottle 40 is placed in the outer bottle 30, the outer diameter of the water leakage prevention ring 48 is larger than the inner diameter of the opening end 32 of the outer bottle 30, and the water leakage prevention ring 48 is placed on the opening end 32 of the inner wall of the outer bottle 30. Since the space is separated from the inner wall of the outer bottle 30 and the outer side of the inner bottle 40, the space 12 is formed to provide a sealing action and the liquid is surrounded by the inner bottle 30 and the outer bottle 40 of the bottle 10. Do not leak into the space 12.

  When the outer bottle 30 is covered with the inner bottle 40, the volume of the space 12 separating the inner bottle 30 and the outer bottle 40 is reduced, and a gas flows into the concave portion 36 to provide a path for releasing the atmospheric pressure. Thereby, the recessed part 36 becomes equivalent to the air vent structure of the bottle 10.

  Further, the thickness of the water leakage prevention ring 48 is thinner than the thickness of the other part of the inner bottle 40, and provides an acting force necessary for the convex portion 41 to return. The convex portion 41 is compressed and passes through the open end 32 of the outer bottle 30, and is restored and engaged with the corresponding concave portion 36 to form an engagement structure, and the inner bottle 30 and the outer bottle 40 are combined. Make it difficult to detach.

Thereby, since the inner bottle 30 and the outer bottle 40 are transparent, the color of the inner bottle 40 can be visually observed, the volume (or water level) of the liquid in the inner bottle 40 can be easily measured, and there are effects such as multicolor and heat retention. Thus, the disadvantage of the conventional bottle being monotonous is improved.
Second Embodiment

  3 and 4 show a second embodiment of the bottle 10. The structure is almost the same as that of the first embodiment, and the difference is that there is no engagement structure, and the water leakage prevention ring 48 is fastened to a position close to the open end 32 of the inner wall of the outer bottle 30.

  Next, the air vent structure is a few groove portions 50, and these groove portions 50 are formed at locations close to the opening end 32 on the inner surface of the outer bottle 30. While the outer bottle 30 covers the inner bottle 40, gas is compressed in the space 12 separating the inner bottle 30 and the outer bottle 40 and leaks out in the direction of the arrow in FIG. .

After the bottle 10 is constituted by the inner bottle 30 and the outer bottle 40, these groove portions 50 are sealed by the medium, and the liquid is prevented from leaking from the groove portion 50 to the space 12 separated by the inner bottle 30 and the outer bottle 40.
<Third Embodiment>

  FIG. 5 shows a third embodiment of the bottle 10. The structure is substantially the same as that of the second embodiment, and the difference is that the water leakage prevention ring 48 is a circumferential surface and has a thickness W of 0.5 mm to 30 mm. Next, the air vent structure is not provided on the inner surface of the outer bottle 30 but provided outside the inner bottle 40. A certain point is that the air vent structure is an annular recess 54 formed at a portion where the water leakage prevention ring 48 enters the outer bottle 30, and similarly, a path for releasing the pressure of the space 12 separated by the inner bottle 30 and the outer bottle 40. It becomes.

Further, the above-described medium (not shown) is added between the water leakage prevention ring 48 and the outer bottle 30. The medium is oil or an adhesive, and enhances the adhesion between the water leakage prevention ring 48 and the outer bottle 30.
<Fourth embodiment>

  FIG. 6 is a fourth embodiment of the bottle 10. The structure is almost the same as that of the first embodiment, and the difference is that the water leakage prevention ring 48 and the convex portion 41 are first separated, but the water leakage prevention ring 48 is different from the space 12 that separates the inner bottle 30 and the outer bottle 40. This is a point that still has a sealing action. Subsequently, the protrusion 41 has a long structure, is designed to be integrated with the inner bottle 40, and is positioned above the water leakage prevention ring 48. When the inner bin 40 is placed in the outer bin 30, the convex portion 41 is engaged with the concave portion 36.
