Portable fridge

technical sector

The present invention refers to a portable refrigerator, which has a multilayer structure from which better preservation performance of the products housed within it are derived.

The refrigerator also has a lid that, in addition to its conventional function as a closing element, can be used as a tray in its overturned position, also allowing the refrigerator to be closed and insulated when it is placed on the mouth of the same in such position.

The object of the invention is to provide a refrigerator with closing means for its lid that allow to obtain an optimal sealing of the lid, thus avoiding the loss of frigories due to a poorly hermetic closure.

background of the invention

Although the use of portable refrigerators is notable, it should be said that normally this type of refrigerators are made from a body with two layers, between which an isolation chamber is established, the same happening with the corresponding lid, which only has the hermetic closing function of said refrigerator.

Ultimately, this type of refrigerator has a limited thermal insulation capacity, which it would be desirable to increase.

Trying to avoid this solution, the applicant himself owns the utility model U201931203, which describes a portable refrigerator in which both the lid and the body of the refrigerator are made up of three layers, an outer layer, an inner layer and an intermediate one for each element.

The intermediate layer is made of EPS, while the outer and inner layers or shells are made of polypropylene, with the three layers being able to finish perimeter at the same edge, or the inner shell may have a small flange so that it overflows and comes out towards the outside, so that no water, sand or dirt can get between the layers.

The three layers that participate in the main body of the refrigerator are affected by a pair of holes in their sides for anchoring the ends of the corresponding handle, anchoring that will be made by means of an O-ring with a female rivet and the complementary male finish, both made of polyamide, the holes obviously facing each other in the three layers that make up the body of the refrigerator.

For its part, the lid adopts a slightly curved convex configuration on its external face, or at least on its perimeter, while on its internal face a flat, stepped recess is defined that, when turned over, becomes a tray. , whose staggering defines a means of stabilization and additional security for the objects placed on it, while the rounded outer edge of the lid allows it to adapt perfectly and tightly to the inner edge of the mouth of the refrigerator, thus avoiding the breaking of the cold chain.

All the edges of the refrigerator will be strongly rounded, in order to achieve optimal ergonomics for the refrigerator.

The essentially inverted truncated pyramid shape with a rectangular base and strongly rounded edges, together with the configuration of the lid, make the belt or carrying handle itself, of a flexible nature, press the lid against the mouth of the main body, by itself. weight of the latter when it is hung from the shoulder or a hand of the user, thus ensuring a perfect closure, without the need to implement expensive and expensive closure mechanisms.

Well, the problem with this device is that, as has just been said, although the lid is pressed against the body of the refrigerator through the handle itself when the refrigerator is transported from said handle, at times when it is not there is tension on the handle, for example if it is deposited on the floor, in a trunk or in the place that is estimated convenient, the tension disappears and consequently the pressure on the lid, which means that its closure does not have enough pressure to guarantee an optimal tightness, which translates into a premature loss of frigories, clearly undesirable.

explanation of the invention

The portable refrigerator that is recommended solves in a fully satisfactory way the problems previously exposed.

To do this, and starting from the same structuring of the refrigerator described in utility model U201931203, it has been foreseen that its handle has a special configuration from which three different operating positions are offered, by means of which an optimal closure is ensured. airtight regardless of how the refrigerator is transported or stored.

More specifically, the handle is made up of two end handle sections of invariable length, which at one end are linked to the body of the refrigerator on respective opposite side faces, and which at the other end are linked to a buckle, complemented by a longer central handle, which presents a series of holes or eyelets that, when used selectively in the buckles of the end handle sections, allow the following assemblies:

In the closed position, the handle adapts tightly to the contour formed by the body of the refrigerator and the lid, guaranteeing the correct closing and tightness of the refrigerator.

Another mounting position offered by the handle is the handbag position.

Finally, the handle offers a third assembly, that of the shoulder position, which is obtained by selecting the eyelets closest to the free ends of the central handle.

In either of these last two mounting positions, while the refrigerator is carried as a handbag or on the shoulder, it will also ensure a perfect Hermetic closing of the lid, since the handle, due to the configuration of the fridge itself, will press on the two lateral edges of the lid, with a force proportional to the weight of the fridge with its contents, more than enough to guarantee a watertight closure from the lid.

The central handle can be complemented with the classic PVC shoulder and hand protector, and said handle can be obtained in different materials, from leather, synthetic, or cotton, not having said central handle having a strictly rectangular configuration, being able to present a configuration as a handkerchief or according to different design lines.

In this way, a refrigerator with high insulation performance is achieved, allowing the products contained within it to be kept between 5 and 15 ° C for up to 12 hours.

preferred embodiment of the invention

In view of the figures outlined, and especially of figure 1, it can be seen how the portable refrigerator of the invention is made up of a main body (1) open at the top and a cover (2) for coupling on the previous one, the refrigerator assembly being complemented with a handle for manual transport of the refrigerator, made up of three elements, two end handle sections (3), and a central handle (3 ').

The main body (1) is formed from three layers, an outer layer (4) as a shell based on polypropylene, an intermediate layer (5) based on EPS, and an inner layer (6) or shell also made of polypropylene, the three elements being coupled to each other to form said main body (1), with the special feature that these elements are affected on their smaller faces by holes (7) coinciding with each other, for the passage of a rivet (9 ) and an O-ring (8) in the attachment of the end handle sections (3).

For its part, the cover (2) is also made up of three layers, an outer layer (11) as a shell based on polypropylene, an intermediate core (10) based on EPS, and an inner layer (12) or casing also based on polypropylene, these three layers being coupled together as was the case with the main body of the refrigerator.

The O-ring (8) and the rivet (9) are made of polyamide.

As previously said, the cover (2) adopts a slightly curved convex configuration on its external face, or at least on its perimeter, while on its internal face a stepped and flat recess is defined that, when given Turning it over, it turns it into a tray, so that the rounded outer edge of the lid allows it to fit perfectly and tightly to the inner edge of the main body (1) of the refrigerator.

Regarding the inner layers or shells of both the cover and the main body, they may be on the same edge as the outer and intermediate shell or, the inner layer may have a perimeter (13) and external flange that covers the other two layers, so that water or dirt cannot be introduced between said layers.

The end handle sections (3), of short length, are finished off at their free end in respective buckles (14), so that the central handle, clearly visible in figure 2, has a considerable length, with a series of holes u eyelets (15,15 ', 15' 'and 15' '') which, when used selectively on the buckles (14), allow the following assemblies:

In the closed position shown in figure 3, the handle adapts tightly to the contour formed by the body of the refrigerator and the lid, guaranteeing the correct closing and tightness of the refrigerator. This option is created by linking the central handle (3 ') to the buckles (14) through the eyelets (15) and (15') or (15 '') and (15 '' ').

Another mounting position offered by the handle is the handbag position, shown in figure 4. This option is created by linking the central handle (3 ') to the buckles (14) through the eyelets (15) and (15 '') or (15 ') and (15' '').

Finally, the handle offers a third mounting, that of shoulder position, the one shown in figure 5. This option is created by linking the central handle (3 ') to the buckles (14) through the extreme eyelets, that is to say, the leaflets (15) and (15 '' ').

The central handle (3 ') may have an axially movable shoulder and hand protector (16) to adapt to the different mounting configurations, so that although in Figure 2 it appears centered on the handle, depending on the position mounting to be obtained must move in one direction or the other.
