Abstract

The thermal insulation bag of the utility model has a corresponding handle, wherein the body and the cover are both composed of three layers, one outer layer (1, 4) based on polypropylene as the outer shell, one middle layer (2, 5) based on EPS and one inner layer (3, 6) based on polypropylene. The internal chamber is set to have a constant horizontal cross section over its entire height so that it can contain a plurality of containers that can be stacked on top of each other, the height of the containers being a divisor of the height of the chamber on which they are stacked, based on the container body (9) and the upper sealing cap (10), thus optimizing the available space.

Description

Thermal insulation bag

Technical Field

The present utility model relates to a thermal insulation bag having a multi-layered structure from which better protection properties can be derived.

The thermal bag is provided with containers which fit perfectly and can be stacked inside it, optimizing its loading capacity.

The object of the present utility model is to provide a thermal insulation bag in a refrigerator such that the food and/or beverage is kept at an optimal consumption temperature for as long as possible.

Background

Although the use of portable thermal containers is very remarkable, it should be said that in general this type of container consists of a body of two layers, between which an insulating chamber is established, as happens on the corresponding lid, which only has the sealing function of the thermal bag.

In short, this type of insulation bag has limited insulation capacity and is therefore expected to increase.

This problem increases when the apparatus is embodied in a thermal bag.

With respect to these limitations, the second problem should be emphasized, namely the distribution of the food product within the thermal insulation bag, so that when different sized containers are used to store the product to be consumed, these containers are often not adapted to the exact dimensions of the interior of the thermal insulation bag, so that it always eventually wastes a large part of the bag's capacity.

Disclosure of utility model

The claimed insulation bag solves the above-exposed problems completely satisfactorily, has no thermal bridge, provides continuous insulation in all interiors, and is structurally optimized for its storage capacity.

For this purpose, the thermal insulation bag of the present utility model is constituted by a body open at the top, the body having a solid circular edge, and a coupling cover at the top of the body, the thermal insulation bag being equipped with a handle for manual/shoulder transport in combination with said body.

More specifically, the body and the cover each have a sandwich-like structure consisting of three layers, an outer layer based on polypropylene as the outer shell, an intermediate layer based on EPS, and an inner layer based on polypropylene, the three layers of the body having corresponding and identical holes on the smaller sides thereof, which serve as channels for securing the transport handles.

The handle is preferably leather and may include means for adjusting its length.

According to another feature of the utility model, the body is designed to define an internal chamber of constant horizontal section over its entire height, whereby the chamber is filled, according to the designed dimensions of said section and the height, with a series of containers that can be stacked on top of each other, so that the containers are adjustably stacked in the insulating bag, whereby the storage space can be optimized once filled with food or product, and whereby the utilization can be up to 100% compared to conventional insulating bags.

These containers will include an upper seal cap surrounded by a peripheral relief (RELIEVE PERTMETRAL) that mates with complementary grooves established on the lower surface of the bottom of the container to achieve an extremely stable stack.

In this way, a thermal insulation bag with high insulation properties can be achieved, which can be kept inside for up to 12 hours at between 5 and 15 ℃.

Figure 3 shows an exploded view of a thermal insulation bag of a multi-layer construction.

Figure 4 shows a perspective view of a tightly stackable container within a thermal bag.

Fig. 5 shows a view similar to fig. 4, but with the container lid open.

Fig. 6 finally shows a longitudinal section through several containers, for example the containers in fig. 4 and 5, which are stacked in position on each other.

Detailed Description

With reference to the figures outlined, and in particular to fig. 2, it can be observed that the thermal insulation bag of the present utility model consists of a body open at the top and a coupling cap at the top of the body, a handle (8) being provided on the thermal insulation bag for manual/shoulder transport.

The body consists of three layers, one outer layer (4) based on polypropylene as the outer shell, one middle layer (5) based on EPS, one inner layer (6) based on polypropylene, which are coupled to each other to form the body, characterized in that the three layers have holes (7, 7') overlapping each other on their smaller faces for passing through rivets and O-rings, in which the end parts of the handles (8) are riveted.

The lid itself is also made up of three layers, one outer layer (1) based on polypropylene as the outer shell, one middle layer (2) based on EPS, one inner layer (3) based on polypropylene, the three layers being coupled to each other as well as the body of the thermal bag.

The handle (8) is preferably leather and may include means for adjusting its length.

Both the body and the cover adopt a slightly curved convex configuration on their outer surfaces, although the inner cavity defines an inner layer (6) which presents a constant horizontal cross section over its entire height.

According to fig. 4 to 6, the thermal insulation bag is filled with a series of containers stacked one on top of the other, the planar dimensions of the containers being in agreement with the dimensions defined by the constant horizontal cross section of the internal chambers in the thermal insulation bag, based on the container body (9) and the upper sealing cap (10), the height of these containers being a divisor of the height of the chambers on which they are stacked, which makes it possible to stack them closely in the chambers of the thermal insulation bag, a predetermined number of containers being able to utilize 100% of the storage space of the thermal insulation bag compared to conventional thermal insulation bags.

It is only to be noted that these containers will comprise a peripheral relief (11) in their sealing cap (10) matching with a complementary recess (12) established on the lower surface of the bottom of said container, as shown in the expanded detail of fig. 6, so as to achieve an extremely stable stack.
