Description

Insulated container

technical field

The utility model relates to a thermal insulation container, more specifically it comprises a double-walled container with an outer wall and an inner wall, wherein there is a space evacuated below the atmospheric pressure between the outer wall and the inner wall, and the double-walled Containers are transparent or translucent.

Background technique

Insulated containers configured as thermos jugs or thermos bottles and often referred to as "thermos bottles" are commonly used to retain the heat of hot beverages or meals over an extended period of time. Most insulated containers comprise double walled containers in which the space between the outer and inner walls of the double walled container is evacuated to reduce heat transfer through the container. In a conventional thermos, the double-walled container is made of metal such as stainless steel, or consists of a one-piece glass bottle with the inner wall facing a reception volume with a reflective coating, thereby The heat emitted by the beverage contained in the cavity is reflected back to the beverage.

Such containers are flawed, they are completely opaque from the outside. Therefore the user cannot observe the inside of the container, and the degree of filling of the container can only be estimated by the weight of the container, which can lead to problems in the case of a wrong estimate.

In an effort to solve this problem, German Patent Publication DE 69715021T2 discloses a thermos bottle in which a double-walled thermos container is coated with a coating for reducing heat generation, the coating being relatively thin so that it is at least translucent , in this way, depending on the type of coating, up to 80% visible light transmission can be obtained.

Coatings with such a transparent or translucent layer are disadvantageous, in particular because of the cost and the resulting additional processing effort.

Utility model content

The object of the present invention is to provide a heat-retaining container which achieves satisfactory thermal insulation and whose filling degree is visible to the user from the outside, which can also be manufactured in a simple and cost-effective manner. become.

The above object is achieved by a heat-retaining container, wherein the heat-retaining container comprises a double-walled container, which has an outer wall and an inner wall, the space between the outer wall and the inner wall is evacuated to lower than atmospheric pressure, and the double-walled The container is transparent or translucent, characterized in that it does not comprise any coating for reducing heat radiation.

However, in traditional double-wall heat-retaining containers, heat-insulating coating is considered indispensable, and the heat-retaining container provided by the utility model is particularly suitable for containing cold food. It is very different from hot food, such as freshly brewed tea or coffee, the temperature difference between them and the environment can reach 60 to 80 ° C, due to the lack of appropriate measures, a large loss due to heat dissipation, the utility model utilizes this Given the fact that the temperature difference between cold food and the environment is usually less than 20° C., the thermal insulation effect of the container evacuated between the double walls is sufficient to avoid undesired heating of the food contained in the thermal container.

In this way, it is possible to produce transparent or translucent thermal containers, such as thermos jugs or flasks, in which the degree of filling of the container is visible from the outside, so that the degree of filling does not have to be observed through the spout. In addition, it is also possible to provide an insulated container in which the color of the contents is visible from the outside, which is particularly desirable especially for cold beverages.

Preferred embodiments of the invention are defined in the claims.

A particularly preferred embodiment of the invention is achieved by making the double-walled container a single part, eg glass. The use of soda glass has proven to be particularly advantageous.

In another preferred embodiment of the present invention, the container is mounted in a casing, thereby protecting the double-walled container from impacts or other environmental influences, wherein in a particularly preferred embodiment of the present invention, The outer shell is also transparent or translucent and thus does not interfere with the advantages of the transparent double-walled container located therein. Such an enclosure has a high gloss on its inner side and is preferably made of polypropylene (PP), SAN or acrylic or acrylic glass (Plexiglass).

According to another preferred embodiment of the present invention, the outer side of the shell is frosted, that is to say matt-treated, so as to enhance the tactility of the thermos jug and also for reasons of the overall visual impression.

Description of drawings

A preferred embodiment of an insulated container realized in accordance with the teachings of the present invention is shown in FIG. 1 , wherein an insulated container configured as a bottle is shown, indicated generally by reference numeral 10 .

Detailed ways

Bottle 10 includes a housing 12 that includes a generally cylindrical shell portion 14 and a bottom side portion 16 that is threaded into shell portion 14 . The at least generally cylindrical shell portion 14 is made of a suitable plastic, such as polypropylene or acrylic. Arranged within the housing 12 is a double-walled container 18 which, in the exemplary embodiment shown, is made of soda glass in one part. Since neither the inner wall 20 nor the outer wall 22 of the double-walled container 18 is provided with a coating for reducing heat radiation as in prior art containers, the double-walled container 18 is transparent. Also due to the fact that the generally cylindrical shell portion 14 is transparent or at least translucent, such as by polishing the inside of the shell portion 14 to obtain a higher gloss, but simultaneously frosting the outside of the shell portion 14, the Both the color of the contents of the bottle 10 and the degree of filling of the bottle 10 are visible to the user.

In the embodiment shown in the figures, for the assembly of the insulated container, the double-walled container 18 is inserted from below into the generally cylindrical shell portion 14 so that the upper edge of the double-walled container 18 abuts against the sealing member 24 , wherein the sealing member 24 is disposed at the upper neck 26 of the shell portion 14 . The bottom side part 16 is then screwed into the shell part 14 so that the double walled container 18 sits on the bottom side part 16 with the upper edge of the double walled container 18 pressed against the sealing member 24 . To seal the interior of the double-walled container 18 after filling, a sealing cap 28 is provided which is screwed into the upper neck 26 of the shell part 14 .
