Description

Thermos liner improved structure

The present invention relates to a container for containing water or a beverage, and more particularly to a liner structure of a plastic thermos bottle.

Most of the thermos bottles that are often used by children or elementary school students are made of plastic materials, and then the glass liner is placed inside the bottle body. The outer surface of the glass liner is coated with a layer of mercury, which is reflected in the inner tank by mercury reflection. The heat of the hot water is used to extend the heat preservation effect of the water temperature during the installation.

Since children or elementary school students are usually more active, the thermos bottles they carry with them are often smashed, causing the fragile glass liner inside to be easily broken by external impact, not only for a short service life, but also for glass. After rupture, mercury coated on the outer surface of the glass liner may dissolve into the water, and may be accidentally left unintentionally, affecting the health of the body; plastic thermos manufacturers are often subject to consumer complaints.

In addition, the weight of the glass liner is often heavier, so the total weight after loading the plastic bottle may be a burden for children or primary school students; especially the textbooks of today's primary school students have a wide variety of books, and they are burdened every day. The schoolbag goes to school, and if you carry a heavy vacuum flask, you will feel more sad.

The purpose of this creation is to provide a liner-improved structure of a plastic thermos bottle that does not rupture, is non-toxic, and is lightweight.

The improved structure of the thermos liner provided by the present invention comprises: a bottle body made of plastic material and having a bottle mouth at the upper end thereof; a base disposed at the lower end of the bottle body; and a liner disposed at The inside of the bottle body, and the lower end of the inner tank is supported by the base; a gasket is sealed between the inner circumference of the bottle mouth and the flange of the upper end of the inner tank; an inner screw cap, the spiral combination The upper end of the bottle body cooperates with the gasket to control whether the opening of the inner tank can pour the liquid contained in the inner tank, wherein the inner liner is made of a stainless steel material and has a container with an inner space.

In another embodiment of the present invention, a layer of tantalum may be formed from the tantalum material on the inner space surface of the inner liner or a layer of titanium metal may be combined to form a titanium metal layer.

Preferably, the creation can form an internal thread on the inner diameter of the lower end of the bottle body, and an external thread is formed on the upper side of the base body, and the internal thread is spirally combined by the external thread to combine the base body with the bottle body.

Preferably, the creation may be provided with an upwardly protruding supporting convex portion at the upper end of the base. When the inner casing is combined with the inner portion of the bottle body and the base is assembled to the lower end of the bottle body, the upper end of the supporting convex portion is supported by the inner tank. The bottom surface.

Preferably, when the inner body is assembled into the bottle body, the outer surface of the inner liner and the inner surface of the bottle body are kept at a distance to form a space around the circumference.

More preferably, the creation can form a concave ring groove at the lower end of the gasket, and the concave ring groove is forced into the flange of the opening at the upper end of the inner casing.

The creation may further include an outer cover for covering the upper end of the bottle body and simultaneously covering the inner screw cap.

With the above-described inner liner structure, since the inner liner is made of a stainless steel material, there is no doubt that the inner liner is broken, thereby protecting the health and safety of the user's drinking water, and the overall weight is lighter than the conventional glass inner liner. It's easier to carry. Furthermore, the inner surface of the stainless steel inner liner can also be combined with a tantalum layer or a titanium metal layer to provide superior corrosion resistance.
