Description

A kind of safety thermos flask

Technical field

The utility model relates to daily living article field, particularly relates to a kind of safety thermos flask.

Background technology

Thermos bottle is being a kind of conventional life appliance, at present, on market, most of thermos bottle is all load bottle inner bag at the bottom of bottle, then base is rotatably connected in shell, due to can be very heavy after topped up with water, because its shell is connected insecure with inner bag, due to Action of Gravity Field, easily cause base to be separated with housing, occur inner bag explosion, hot water is excessive, splash, the security incident such as also can cause time serious that scald and glass are hurted sb.'s feelings; Meanwhile, general glass liner, without any safeguard measure, when after the hot water loading high temperature, because inner bag internal gas pressure sharply raises, once suffer external force or coming off, easily produces blast, has great danger; And the handle of general thermos bottle mostly is Plastic Welding on lower casing, easily causes the problem that handle comes off, brings potential safety hazard to use.

Summary of the invention

The purpose of this utility model is to provide a kind of safety thermos flask, is connected insecure to solve vacuum bottle shell in prior art with inner bag, base and the problem such as housing is easily separated.

The utility model solves the problems of the technologies described above adopted scheme: a kind of safety thermos flask, comprise bottle stopper, inner bag, handle, upper shell, handle, lower casing, external screw thread, internal thread, nut, described bottle stopper is on inner bag, described inner bag to be placed in lower casing and to stretch out from upper shell, described lower casing and handle are connected as a single entity, described lower casing is provided with handle, and described handle is connected by nut with lower casing, and the internal thread of described lower casing is connected with the external screw thread of upper shell is supporting.

As preferably, described upper shell and lower casing are made up of PP (polypropylene) or stainless steel, and its thickness is about 2 ~ 3mm.

As preferably, the length of described external screw thread and internal thread is about 5 ~ 7mm.

The beneficial effect of a kind of safety thermos flask of the utility model is:

(1) a kind of safety thermos flask of the present utility model, setting is connected with lower casing and internal thread with external screw thread by upper shell, convenient and simple, vacuum bottle shell is connected as a single entity, the problem avoiding traditional inner bag to slip out from base, reduces the possibility of accidental explosion.

(2) a kind of safety thermos flask of the present utility model, by arranging two cover handles, decreasing thermos bottle due to weight after topped up with water and becoming large, conventional grip or handle are due to aging and do not support its weight, cause the accident that thermos bottle is dropped, there is very high practicality.

(3) a kind of safety thermos flask of the present utility model, by the connection of handle and lower casing, make inner bag more can safety be placed in lower casing, add the security relative to conventional hot water's bottle and globality.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described in detail.

As shown in Figure 1, Figure 2, Figure 3 shows, a kind of safety thermos flask, comprise bottle stopper 1, inner bag 2, handle 3, upper shell 4, handle 5, lower casing 6, external screw thread 7, internal thread 8, nut 9, described bottle stopper 1 covers on inner bag 2, described inner bag 2 to be placed in lower casing 6 and to stretch out from upper shell 4, described lower casing 6 is connected as a single entity with handle 5, described lower casing 6 is provided with handle 3, described handle 3 is connected by nut 9 with lower casing 6, and the internal thread 8 of described lower casing 6 is connected with the external screw thread 7 of upper shell 4 is supporting.

In the present embodiment, a kind of safety thermos flask of design, puts into lower casing 6 by inner bag 2 during use, is then threaded connection through inner bag 2 and lower casing 6 by upper shell 4, pours hot water into, cover bottle stopper 1.In the present embodiment, setting is connected with lower casing 6 and internal thread 8 with external screw thread 7 by upper shell 4, avoid the problem that traditional inner bag 2 slips out from base, reduce the possibility of accidental explosion, by handle 3 connection with lower casing 6, decrease thermos bottle due to weight after topped up with water and become large, conventional grip 5 or handle 3 are due to aging and do not support its weight, cause the accident that thermos bottle is dropped, add the security relative to conventional hot water's bottle and globality.

The content that above-described embodiment is illustrated should be understood to these embodiments only for being illustrated more clearly in the utility model, and be not used in restriction scope of the present utility model, after having read the utility model, the amendment of those skilled in the art to the various equivalent form of value of the present utility model has all fallen within the application's claims limited range.
