Description

COOLING CONTAINER -

  The present invention relates to a container in which it is possible to cool certain products such as, for example, canned drinks or any other kind of product requiring to be cooled or kept at a

  low temperature for a period of time.

  The container comprises an airtight chamber containing a liquid which is previously frozen in order to reuse it as a means for cooling a product.

contained in the same container.

  There are different kinds of containers intended to keep certain products like refreshing drinks cold, etc., but in general the basis of all these containers is the use of insulated bodies, the sole purpose of which is to prevent the thermal level from reaching

  the interior does not extend to the exterior.

  In this sense, we can cite, as very well known examples, the classic camping coolers, the principle of which is a double chamber, generally insulated by an air chamber or padding, and which admit ice or cooled blocks arranged between the content that we intend to keep at a low temperature. This kind of container is, however, passive, or otherwise

  said, only serves to isolate the cold product from the outside.

  The invention proposes a cooling container by means of which it is possible to keep any product placed inside it cold, and although in principle its purpose is to keep this product cold for a few hours, as is the case for a canned or bottled drink, the container in question is valid for carrying out these functions, for example for the transport of medicines, analytical samples and in general whenever it is necessary to keep the temperature d 'an object or product during transport. This is achieved by adding negative temperature accumulated in a container, which naturally occurs on the product in the container. This negative temperature is transferred to the container itself by introducing it into a cooling chamber, such as a freezer or domestic refrigerator, and said temperature is accumulated there by freezing a liquid fluid contained in

  a sealed chamber provided in the container itself.

  More concretely, the container is constituted by two tubular bodies which are concentric with each other and among which is determined a chamber which also affects the bottom, this chamber, occupied almost entirely by a liquid capable of freezing on cooling, is closed and hermetically sealed and the entire container is completed by a lid which fits perfectly on the mouthpiece to prevent the cold from going outside, which allows most of the cold to transfer to the product as the we want to cool

  which is inside the container.

  It is obvious that the use of a container according to the invention is practical and advantageous since it solves a large number of situations such as, for example, the problem of delivering a cold drink at a cost that is not necessarily high, and even quite cheap, and given the simplicity of the container and the material

  manufacturing, its final cost will be reduced.

  At the same time, the volume and weight are also reduced, which makes it suitable for a backpack, a sports bag, a glove box, etc. and it also takes up very little space in the domestic refrigerator freezer

while waiting to be used.

  To complete this description and for the purpose

  to assist in a better understanding of the characteristics of the invention, an assortment of drawings is attached to this description and forms part of it. In these drawings there is shown, in a broad and non-limiting sense the following: - Figure 1 shows a perspective representation of the container with the two concentric tubular bodies between them and the interior of which appears in the partial housing position on the outside and the cover in independent position and opposite to

the mouth of the container.

  - Figure 2 shows a representation along a section in elevation of the cooling container with the

cover independent of it.

  At the sight of these figures it can be noted that the container proposed by the invention consists of two tubular bodies (1) and (2), concentric with each other, o, preferably and advantageously, the external body (1) is thicker than the inner body (2). These concentric bodies (1) and (2) are slightly distant, it is the same with regard to their lateral surface and their bottom, and between them is constituted an airtight chamber (3) containing a liquid (4) which occupies the most of its volume, liquid (4) which is freezable, which implies that it does not completely fill the chamber

waterproof (3).

  To obtain this seal between the tubular bodies (1) and (2), provision has been made for the inner body to have an outer perimeter wing (5) whose edge (6) bears on the contour of the inner lateral surface of the outer body ( 1) and, more precisely, on the step (7) provided for this purpose at the upper part, step formed by the fact that the own upper section of the wall of said outer body (1) has a reduced thickness or, which

  returns to the last one has undergone an internal facelift.

  This location or support of the perimeter edge (6) of the wing (5) corresponding to the inner body (2) on the step (7) of the outer body (1) will be sealed by any conventional system to obtain sealing airtight chamber (3) which forms between the two

body (1) and (2).

  The container thus formed is completed by a cover (8) formed by a sort of inverted casserole dish whose perimeter wing or skirt (9) has an external stage (10) from which the thickness of this wing or skirt (9) decreases by taper towards the lower edge for

  promote self-centering of the cover (8).

  The lower edge of this skirt or wing (9) of the cover will bear on the perimeter wing (5) of the internal body (2) while the external stage (10) of said skirt (9) will be pressed exactly on the edge upper (11) belonging to the mouth of the container

general.

  According to this design and drawings of the cooling container, it will suffice to freeze the fluid or liquid (4) contained in the sealed chamber (3) to then introduce into the interior (12) of the container the product which it is desired to cool. or keep cold for a period of several hours, because the cold of this frozen liquid (4) will be transmitted to the product contained in the container, which will cool it, thus the number of hours during which it will be possible to maintain the cold content, or the product, which amounts to the same, is a direct function of the temperature of the frozen liquid (4) as well as the temperature of the product contained and thermal variations with respect to the outside. So, for example, at an ambient temperature of around 24 c and with a freezing of the fluid or liquid (4) from 5 to 10 below zero, the product introduced inside will be at a temperature between 10 and 12 "below room temperature after six

or eight o'clock.

  There is no need to expand this description

  so that any expert in the field can understand the scope of the invention and the advantages arising therefrom. The materials, shape, dimensions and arrangement of the elements may be modified provided that this does not imply

  a change in the intrinsic nature of the invention.

  The terms used to describe this

  memory should always be considered in a broad sense

and not limiting.
