Description

[Detailed Description of the Invention] The present invention relates to a thermos bottle, and particularly relates to a vacuum glass bottle that will not be damaged even if it is accidentally dropped.

The purpose of the present invention is to cover a vacuum glass bottle that is easily damaged with an elastic foamed resin jacket, and to improve the cushioning properties by creating a gap between the two and using a bag-like resin covering. To provide a thermos bottle that enhances portability and does not impair heat retention.

In order to meet the above objectives, the present invention is constructed as follows.

That is, in the present invention, the outer periphery of a vacuum glass bottle 1 is wrapped with a bag-like covering body 3 with a gap 2 in between, and the covering body 3 is further covered with a jacket body 4 made of elastic foamed resin. The upper end of 3 is cap 5
A backing 8 is interposed between the member 7 and the rim of the bottle 1, and the outer periphery of the backing 8 is surrounded by a heat insulating ring 9. A small diameter portion 1 surrounding the protrusion 16 of the bottle 1 at the lower part of the housing 3
5, an intermediate backing 19 is fitted in the small diameter part, and a stop pin 18 is fitted in the small diameter part center hole 17.

In the illustrated embodiment, in order to make the vacuum glass bottle 1 replaceable, the upper part of the packaged body 3 is expanded slightly, and a separate elastic layer is formed between the inner periphery and the cushioning rubber backing 8 applied to the top end of the bottle 1. A ring 9 made of a foamed resin material is fitted to enhance the heat and cold insulation effect at the end of the bottle where heat and cold easily escape. The screws 11 are screwed together for binding.

In the figure, reference numeral 12 denotes an inner stopper provided on the spout member 7, and has a female screw 14 that is screwed into the female thread 13.

Reference numeral 15 denotes a small diameter tubular portion of the packaged body 3 excluding the air vent protrusion 16 of the bottle 1, into which a center hole 17 of the diameter portion 15 smaller than the outer body 4 and a stop pin 18 are fitted.

Further, an intermediate notching 19 is fitted inside the tubular small diameter portion 15.

And the bottle 1 has a cushioning rubber backing 8 and a rubber intermediate:
It is held from above and below by backing 19.

The present invention has the above-mentioned configuration, and since the upper end of the covered body is tied to the spout member 7 to which the cap is attached, when the cap 5 is screwed into the tightening screw 6 of the spout member, a bag-like covering is formed. body 3
A pulling effect is generated to ensure that the vacuum glass bottle 1 can be held securely, and the gap 2 between the vacuum glass bottle 1 and the covering body 3 improves the cushioning and heat insulation properties against external forces. Since the vacuum glass bottle 1 is covered by the vacuum glass bottle 4, there is no risk of the vacuum glass bottle 1 being damaged even if it is dropped, and it is excellent in portability.

In particular, according to the present invention, the backing 8 is interposed between the rim of the bottle and the spout member 7, and the outer periphery of the backing 8 is surrounded by the heat-insulating tongue 9, so that a sufficient heat-retaining effect can be achieved even in the layer around the rim of the bottle. At the same time, it can be expected to have sufficient cushioning properties against external forces, and together with the cushioning effect of the stop pin 18 and the intermediate backing 19 at the bottom of the bottle, the strength in all directions around the glass bottle is improved. This has the effect of effectively protecting the bottle from damage.
