Description

  The present invention relates to a versatile hot water bottle made of plastic.

  The present inventor has been involved in the production of plastic hot water bottles, and has applied for the developed technology as needed. Among them, one that has been well received is Japanese Utility Model Publication No. 62-36710 (Registration No. 1961119). This hot water bottle has remarkable features such that it can be set up, does not take up space when displayed, and only needs to be set up when draining. Japanese Patent Laid-Open No. 2001-170097 (Japanese Patent No. 3295405) is an improvement in that a cover is attached to a hot water bottle.

  These conventional products are obtained by remarkably improving the hot water bottle. On the other hand, there are many heating appliances used in winter besides hot water bottles, and some of them can be used as hot water bottles. If the dual use can be realized, the number of objects to be used can be reduced, which is useful.

  From such a viewpoint, there is a heat insulator of utility model registration No. 3055792. However, the issue of the same issue cannot be said to be devised for ease of use in each application, just because it can be used for many purposes. On the other hand, the hot water bottle disclosed in Japanese Patent Application Laid-Open No. 2005-13355 has a shiatsu protrusion formed on the upper surface of the hot water bottle body with the intention of being usable for purposes other than heating. This is a hot water bottle provided with a depression for footrest and a protrusion for acupressure, and is not more than that.

  By the way, hot water bottles are used by injecting hot water, and it expands while it is in a heated state, and since the internal pressure decreases as the hot water cools down, the expansion and contraction are repeated during use. Accompanied by severe stress changes. In particular, in the case of a plastic hot water bottle, how to withstand expansion and contraction is a key point in manufacturing, and therefore, the manufacturer concentrates on grasping the conditions. However, it is judged that the uneven reinforcing rib described in the above invention cannot withstand expansion and contraction.
