Description

Caja isotérmica.Isothermal box

Object of the invention

La presente invención se refiere a una caja isotérmica, del tipo de las estructuradas mediante la combinación funcional de un cuerpo y una tapa, capaces de establecer un cierre hermético y a base de un material con un elevado coeficiente de aislamiento térmico, como por ejemplo el polipropileno expandido EPP.The present invention relates to a box isothermal, of the type of structured by the combination functional of a body and a lid, capable of establishing a closure Hermetic and based on a material with a high coefficient of thermal insulation, such as expanded polypropylene PPE

El objeto de la invención es dotar a una caja convencional de este tipo de medios de agarre manual que asegure una larga vida útil para la misma.The object of the invention is to provide a box conventional of this type of manual gripping means that ensures A long service life for it.

Background of the invention

Tal como se ha apuntado en el párrafo anterior, y con independencia de otros tipos de cajas que no vienen al caso, existen cajas isotérmicas estructuradas a base de un cuerpo con elevado coeficiente de aislamiento térmico pero escasa resistencia mecánica, como por ejemplo el polipropileno expandido EPP, a cuya embocadura es acoplable machihembradamente una tapa de similares características, capaz de establecer un cierre hermético con el cuerpo y, consecuentemente, de mantener durante un periodo de tiempo mas o menos largo, pero en cualquier caso considerable, una temperatura constante en su interior.As noted in the previous paragraph, and regardless of other types of boxes that are not relevant, there are structured isothermal boxes based on a body with high thermal insulation coefficient but low resistance mechanical, such as EPP expanded polypropylene, whose mouthpiece is tongue and groove a similar lid features, able to establish a tight seal with the body and, consequently, to maintain for a period of more or less long time, but in any case considerable, a constant temperature inside.

Para la manipulación de estas cajas se hace preciso dotarlas de una pareja de asas contrapuestas, que en la actualidad se materializan en regruesamientos de la pared del cuerpo, afectados por una profunda ranura interior e inferior, dimensionalmente adecuada para permitir la introducción de los dedos de la mano, de manera que los esfuerzos debidos al peso de la caja y su contenido se concentran sobre una especie de faldón lateral y externo cuya resistencia mecánica se ve considerablemente disminuida por su escaso espesor y por su propia naturaleza, con lo que es frecuente que se produzca la rotura del mismo, con el consecuente deterioro de la caja, que puede llevar incluso a anularla funcionalmente, desde el punto de vista de manipulación.For the handling of these boxes it is done they must be provided with a pair of opposing handles, which in the currently they materialize in wall thickets body, affected by a deep inner and lower groove, dimensionally adequate to allow the introduction of fingers, so that the efforts due to the weight of the box and its contents are concentrated on a kind of skirt lateral and external whose mechanical resistance looks considerably diminished by its small thickness and by its own nature, with what that it is frequent to break it, with the consequent deterioration of the box, which can even lead to cancel it functionally, from the point of view of handling.

Description of the invention

La caja isotérmica que la invención propone ha sido concebida y estructurada en orden a resolver de forma plenamente satisfactoria la problemática anteriormente expuesta.The isothermal box that the invention proposes has been conceived and structured in order to solve in a way fully satisfying the problem above exposed.

Para ello de forma mas concreta y a partir de la estructuración básica de cualquier caja convencional de este tipo, la caja que se preconiza centra sus características en el hecho de que también en dos zonas lateralmente contrapuestas de la misma, incorpora sendas protuberancias externas en funciones de asa, que en lugar de presentar las profundas ranuras a que se ha hecho mención con anterioridad, presentan una cara inferior ligeramente inclinada hacia abajo y hacia fuera, lo que mantiene las prestaciones desde el punto de vista de agarre manual y elimina por completo su riesgo de rotura, al no suponer ningún tipo de debilitamiento para el cuerpo de la caja, ni tampoco para las protuberancias en forma de asas de las mismas.To do this more concretely and from the basic structuring of any conventional box of this type, the box that is recommended focuses its characteristics on the fact that also in two laterally opposed areas of it, incorporates external protuberances in functions of handle, which instead of presenting the deep grooves that have been made mentioned earlier, they have a slightly lower face tilted down and out, which keeps the performance from the point of view of manual grip and eliminates by complete your risk of breakage, not assuming any type of weakening for the body of the box, nor for protrusions in the form of handles thereof.

Preferred Embodiment of the Invention

A la vista de las figuras reseñadas puede observarse como la caja que se preconiza, como cualquier caja convencional de este tipo, está constituida mediante la combinación de un cuerpo (1) y una tapa (2) a base de un material termoaislante de escasa resistencia mecánica, capaces de definir un compartimento estanco cuando se acopla machihembradamente, concretamente mediante un nervio perimetral (3) de que está provisto el cuerpo a nivel de su embocadura, y una acanaladura complementaria (4) de que está provista la tapa (2) y en la que penetra ajustadamente el nervio (3).In view of the figures outlined you can look like the box that is recommended, like any box Conventional of this type, is constituted by the combination of a body (1) and a cover (2) based on a heat insulating material low mechanical resistance, capable of defining a compartment tight when it is tongue and grooved, specifically by a perimeter nerve (3) of which the body is provided at the level of its mouth, and a complementary groove (4) of which it is provided with the cover (2) and in which the nerve penetrates tightly (3).

A partir de esa estructuración básica convencional, como cualquiera otra para el cuerpo y tapa de la caja, la invención se centra en el hecho de que el citado cuerpo (1) incorpora, en dos puntos contrapuestos, sendas protuberancias (5) proyectadas hacia fuera, sobre las que asienta también la tapa (2) como se observa especialmente en la figura 2, y que presenta la particularidad de que su cara inferior (6) que constituye la zona de apoyo para los dedos de la mano del usuario, configura un plano inclinado, con pendiente orientada hacia abajo y hacia fuera, rematándose en un vértice (7) notablemente redondeado, con lo que se consigue un doble efecto beneficioso, por un lado el asa queda definida por un bloque compacto, sin debilitamientos que supongan un riesgo para el mismo, y por otro lado la protuberancia (5) configura una zona ergonómica de agarre manual, que ofrece unas óptimas prestaciones desde el punto de vista de facilidad de manejo.From that basic structuring conventional, like any other for the body and lid of the box, the invention focuses on the fact that said body (1) incorporates, in two opposing points, protuberances (5) projected outwards, on which the lid also sits (2) as seen especially in Figure 2, and which presents the particularity that its lower face (6) that constitutes the area support for the user's fingers, set a plane inclined, with slope oriented downwards and outwards, finishing off in a vertex (7) remarkably rounded, with what a double beneficial effect is achieved, on the one hand the handle is defined by a compact block, without any weakening a risk to it, and on the other hand the bump (5) set up an ergonomic hand grip area, which offers some optimal performance from the point of view of ease of driving.

Complementariamente y en este aspecto ergonómico, se ha previsto también que la cara lateral y externa (8) de las protuberancias (5) esté ligeramente inclinada hacia arriba y hacia dentro, y que el borde lateral y correspondiente (9) de la tapa (2) se sitúe en prolongación de dicha cara (8) y con un progresivo incremento de su inclinación, en orden a conseguir una perfecta adaptabilidad del brazo del usuario a la caja, como se también se desprende de la observación de la figura 2.Complementarily and in this aspect Ergonomic, it is also planned that the lateral and external face (8) of the protuberances (5) are slightly inclined towards up and in, and that the lateral and corresponding edge (9) of the cover (2) is placed in extension of said face (8) and with a progressive increase in its inclination, in order to achieve a perfect adaptability of the user's arm to the box, as It also follows from the observation in Figure 2.
