Description

Insulation cup improved structure

The present invention relates to a container for holding a liquid, in particular, an improved structure of a vacuum cup which is easier to clean than a conventional stainless steel vacuum cup and which does not contain a beverage after the beverage is used.

The general single-layer stainless steel vacuum flask has no heat insulation effect, so the outer surface of the cup body is very hot after being filled with hot water, and the user is easily burnt if accidentally, and the heat preservation effect is not good because of the rapid heat dissipation.

The double-layer vacuum heat-insulating mug is a product that has been favored by consumers in recent years. It is made by setting the side wall of the cup of the thermos cup into a double-wall structure of stainless steel, and completely withdrawing the air between the double walls to form a vacuum. The liquid contained in the cup body cannot be exchanged heat through the air between the double walls as a medium, thereby greatly reducing the heat exchange speed inside and outside the cup and achieving a good heat preservation effect.

In addition to the above-mentioned double-layer vacuum heat-insulation mug, in addition to boiling water, consumers often use beverages such as tea, coffee, soft drinks, cola, juice, etc. to keep warm or keep cold; however, due to the stainless steel material in the thermos cup The surface of the wall has a large concave hole under the observation of a magnifying glass or a low-magnification microscope, so that it is easy to leave odor in the cup after the beverage such as tea, coffee, soft drink, cola, juice, etc., which causes the taste to be affected when the next beverage is served. With taste, and The conventional double-layer vacuum heat-insulating thermos cup is prone to produce tea scale after being filled with tea, and the cleaning is very difficult, and it is easy to form a sanitary concern.

The purpose of this creation is to solve the aforementioned drawbacks of the conventional double-layer vacuum insulated cup made of stainless steel.

The improved structure of the heat preservation cup of the present invention is characterized in that an inner cup body made of a glass material is disposed in an outer cup body of a double-walled vacuum heat-dissipating side wall made of stainless steel, and the inner cup body and the outer cup body are provided. A positioning ring and a positioning base are disposed between the positioning ring and the positioning base to position the inner cup body in the outer cup body, and the liquid heat in the inner cup body can be insulated or kept cold by using the vacuum heat-dissipating effect of the outer cup body. In addition, the inner cup made of the glass allows the user to conveniently insert or remove the outer cup and is easy to clean, so that any beverage can be contained at will without any fear of residual odor or unsanitary inside the cup.

The invention provides an improved structure of the heat preservation cup, and the technical means thereof may include: an outer cup body having a first opening at the upper end, the first opening extending vertically downward to form a first inner space, the outer cup body having a side wall The outer diameter of the upper end of the side wall forms a first external thread, and the side wall includes an outer wall and an inner wall, and a space for forming a vacuum is formed between the outer wall and the inner wall; an inner cup has a second opening at the upper end The second opening extends vertically downward to form a second inner space, the inner cup has an outer diameter smaller than the inner diameter of the outer cup; a fixing seat has a central hole, and a periphery is formed at the outer periphery of the fixed seat a second external thread, and a first internal thread formed on the inner side of the fixing seat, the fixing seat being screwed to the first external thread of the outer cup by the first internal thread to be mounted on the outer cup An upper end of the first opening; a positioning base mounted under the inner cup a positioning ring mounted on an outer diameter between the upper end and the lower end of the inner cup; and a cover having a second internal thread, the second internal thread and the second external thread of the fixing seat After the positioning base and the positioning ring are mounted on the inner cup body, the inner cup body and the positioning ring are mounted together with the positioning base in the first inner space of the outer cup body, The inner ring body is in contact with the inner wall of the outer cup by the positioning ring and the positioning base.

Preferably, the outer diameter of the inner cup body can form a positioning ring groove, the positioning ring is tightly fitted to the positioning ring groove, and the outer diameter of the positioning ring protrudes the outer diameter of the inner cup body, so that The positioning ring mounted to the inner cup can be securely fixed to the inner cup.

In the present invention, the positioning ring can be mounted on the outer diameter of the inner cup at a distance from the upper end of the inner cup, thereby providing a better positioning position above the inner cup and the outer cup.

Preferably, the present invention can form a bottom portion on the positioning base, and vertically extend a height upwardly around the bottom portion to form a side wall, so that the outer diameter of the inner cup body can be tightly fitted into the side wall of the positioning base. The path is positioned.

In an embodiment of the present invention, the fixing base may be formed in a class shape in the axial direction and have an upper section and a lower section, the outer diameter and the inner diameter of the upper section being smaller than the outer diameter of the lower section. An inner diameter, wherein the second external thread is formed at an outer diameter of the upper portion, and the first internal thread is formed at an inner diameter of the lower portion.

In a preferred embodiment of the present invention, the outer cup system is fabricated from a stainless steel material and the inner cup system is fabricated from a glass material.

In a preferred embodiment of the present invention, the positioning ring and the positioning base can be softly molded. Made of glue, silicone or rubber.

With the improved structure of the above-mentioned heat preservation cup, since the inner cup body can be freely separated and combined with the outer cup body, and the inner cup system is made of glass material, it is easy to clean and the surface is smooth without fine recessed holes, so that it can be safely The inner cup contains any beverage without worrying about hygiene issues, or concerns about taste and taste after serving different beverages.
