Description

Embalaje con medio de cierre angular con hendidura de pinzado. Packaging with angular closure means with pinch groove.

La presente invención se refiere a un embalaje para el acondicionamiento de productos alimenticios, compuesto por un recipiente y una tapa que dejan subsistir entre ellos unas hendiduras de aireación. La existencia de dichas hendiduras implica necesariamente que los medios de cierre estén localizados, en este caso, en las zonas angulares. The present invention relates to a packaging for the conditioning of food products, consisting of a container and a lid that allow aeration grooves to remain between them. The existence of said grooves necessarily implies that the closing means are located, in this case, in the angular zones.

Dado que las zonas de cierre son limitadas y tributarias de una geometría angular, los medios de cierre obedecen a una concepción particular destinada a conferirles unas características mecánicas adaptadas. Se han propuesto ya unos medios de cierre angulares, por ejemplo en la patente EP 0 784 019 a nombre de la solicitante, que describe un embalaje de acuerdo con el preámbulo de la reivindicación 1. Since the closing areas are limited and tributary of an angular geometry, the closing means obey a particular conception intended to give them adapted mechanical characteristics. Angular closure means have already been proposed, for example in EP 0 784 019 in the name of the applicant, which describes a package according to the preamble of claim 1.

Estos medios de cierre comprenden una garganta practicada en cada zona angular, en el recipiente o en la tapa, cuya pared exterior presenta una contradespulla situada al nivel alto de la pared interior y que limita en toda su longitud la abertura superior de dicha garganta. These closing means comprise a throat made in each angular area, in the container or in the lid, whose outer wall has a counter-spout located at the high level of the inner wall and that limits the upper opening of said throat throughout its length.

Sin embargo, esta configuración, que funciona perfectamente bien, adolece del inconveniente de permitir únicamente una capacidad de apilamiento restringida, en la medida en que el apilamiento de dos embalajes sucesivos está limitado a tope en la inserción, por dichas despullas. However, this configuration, which works perfectly well, suffers from the disadvantage of allowing only a restricted stacking capacity, to the extent that the stacking of two successive packages is limited to the insertion limit, by said pullets.

Entre los fondos de dichos recipientes subsiste en la práctica un espacio residual cuya altura asciende a algunos milímetros. Esto puede parecer poco, pero el espacio perdido pasa a ser considerable cuando se suministran los embalajes, en estado vacío, en gran cantidad. En este caso, se apilan y están constituidos en apilamientos que cuentan con varias decenas de embalajes, y la pérdida de volumen total se vuelve rápidamente importante. Among the bottoms of said containers, there remains in practice a residual space whose height amounts to a few millimeters. This may seem little, but the lost space becomes considerable when the packages are supplied, in an empty state, in large quantities. In this case, they are stacked and constituted in stacks that have several dozen packages, and the total volume loss quickly becomes important.

El objetivo de la presente invención es evitar este inconveniente y permitir un encajado máximo, fondo contra fondo, que permita conseguir al final una ganancia de volumen importante, con una incidencia económica notable, especialmente a la vista de los costes de transporte. The objective of the present invention is to avoid this inconvenience and allow a maximum fit, bottom to bottom, which allows to achieve in the end a significant volume gain, with a notable economic impact, especially in view of transport costs.

Con este fin, el embalaje según la invención, y tal como se le define por la reivindicación 1, se caracteriza porque los medios de cierre consisten en una garganta practicada en el borde de cada zona angular de uno de los componentes constituidos por el recipiente o la tapa y apta para guiar y alojar elásticamente un reborde externo del otro de dichos componentes, comprendiendo dicha garganta por lo menos una incisión o corte practicado al nivel del fondo en una longitud por lo menos igual a la longitud de dicho reborde externo, el cual está provisto de una arista libre que se pinza por inserción en la incisión cuando ésta llega al nivel de dicho reborde. To this end, the packaging according to the invention, and as defined by claim 1, is characterized in that the closing means consist of a throat formed at the edge of each angular area of one of the components constituted by the container or the cover and able to guide and elastically accommodate an external flange of the other of said components, said throat comprising at least one incision or cut made at the level of the bottom at a length at least equal to the length of said external flange, which It is provided with a free edge that is clamped by insertion into the incision when it reaches the level of said flange.

En otros términos, la función de enclavamiento en la garganta, antes reservada a la despulla, se recupera ahora por la existencia de la incisión o del corte practicado al nivel del fondo, en el que viene a quedar pinzado el reborde externo. Esta solución elimina la necesidad de un volumen que invada el interior de la garganta, terminando de hecho por añadir a la función de enclavamiento deseada una segunda función no deseada, la de tope para el apilamiento. In other words, the throat interlocking function, previously reserved for eviction, is now recovered by the existence of the incision or the cut made at the bottom level, in which the outer flange is clamped. This solution eliminates the need for a volume that invades the inside of the throat, ending in fact by adding to the desired interlocking function a second unwanted function, the stop for stacking.

Según una configuración posible, el fondo puede comprender dos incisiones de aspecto paralelo. El interés de la incisión es especialmente evitar que se tengan que evacuar desechos cortados en el curso de la fabricación de cada embalaje. According to a possible configuration, the bottom may comprise two incisions of parallel appearance. The interest of the incision is especially to avoid having to dispose of cut waste in the course of manufacturing each package.

Por consiguiente, dado que, propiamente hablando, la incisión no es un orificio provisto de una superficie propia, el pinzado se efectúa deformando los labios que la limitan. Esta deformación se efectúa más fácilmente cuando están practicadas paralelamente dos incisiones. La banda de material que se encuentra entre las dos incisiones permite en efecto, en el momento y debido a los contactos sin tensión, la creación de un vaciado que favorece el pinzado. Therefore, since, properly speaking, the incision is not a hole provided with its own surface, the clamping is effected by deforming the lips that limit it. This deformation is most easily performed when two incisions are made in parallel. The band of material that is between the two incisions allows, in effect, due to the contacts without tension, the creation of a recess that favors clamping.

Más precisamente, la garganta y el reborde externo pueden presentar una forma de aspecto en V de fondo plano, estando la hendidura y la arista libre localizadas al nivel de la pared exterior respectivamente de dicha garganta y dicho reborde externo. More precisely, the throat and the outer flange may have a flat-bottomed V-shaped shape, the groove and the free edge being located at the level of the outer wall respectively of said throat and said outer flange.

De hecho, la arista libre limita una porción que sobresale de la pared exterior del reborde externo y que está orientada sustancialmente en la dirección de su fondo. Esta orientación es igual que la del fondo de la garganta en la fase final de cierre y permite de hecho el enclavamiento después del pinzado. In fact, the free edge limits a portion that protrudes from the outer wall of the outer flange and that is oriented substantially in the direction of its bottom. This orientation is the same as that of the bottom of the throat in the final phase of closure and in fact allows interlocking after clamping.

Según la invención, las zonas angulares de cierre están configuradas en arco de círculo, estando las gargantas practicadas en unas orejetas que sobresalen hacia el exterior de las paredes de uno de los componentes constituidos por el recipiente o la tapa y de aspecto paralelo a su fondo y que forman el borde exterior en dichas zonas. Los rebordes externos previstos para cooperar con las gargantas forman a su vez la prolongación de las paredes del otro de dichos componentes. According to the invention, the angular closing zones are configured in an arc of a circle, the throats being formed in lugs that protrude towards the outside of the walls of one of the components constituted by the container or the lid and of an aspect parallel to its bottom and that form the outer edge in said areas. The external flanges intended to cooperate with the throats in turn form the extension of the walls of the other of said components.

Según una posibilidad, las gargantas y los rebordes externos forman sustancialmente un cuarto de círculo. According to one possibility, the throats and outer flanges form substantially a quarter of a circle.

Varias hipótesis de embalaje según la invención pueden comprender unos medios de cierre según las 5 características mencionadas anteriormente. Así, la tapa y el recipiente pueden estar separados y comprender cuatro zonas angulares de cierre. Several packaging hypotheses according to the invention can comprise closing means according to the 5 characteristics mentioned above. Thus, the lid and the container can be separated and comprise four angular closure zones.

Como alternativa, dichos medios de cierre pueden equipar dos zonas angulares enfrentadas a una bisagra que une el recipiente y la tapa. 10 Preferentemente, las gargantas están practicadas en los bordes de las zonas angulares del recipiente. Alternatively, said closing means can equip two angular zones facing a hinge that joins the container and the lid. 10 Preferably, the throats are made at the edges of the angular areas of the container.

25 Haciendo referencia a las figuras 1 y 2, el embalaje de la invención se compone de un recipiente (1) y una tapa (2). En el ejemplo representado estos dos elementos están unidos por una bisagra (3) que equipa uno de los lados longitudinales de la tapa (2) y el recipiente (1). With reference to Figures 1 and 2, the packaging of the invention consists of a container (1) and a lid (2). In the example shown, these two elements are joined by a hinge (3) that equips one of the longitudinal sides of the lid (2) and the container (1).

30 Por consiguiente, los medios de cierre según la invención únicamente afectan a las dos zonas angulares (4) y (5) situadas en posición opuesta a dicha bisagra (3). Estos medios de cierre comprenden unas gargantas (6) localizadas en el borde de las zonas angulares del recipiente (1), y previstas para cooperar con unos rebordes externos (7) de la tapa (2). Accordingly, the closing means according to the invention only affect the two angular zones (4) and (5) located opposite to said hinge (3). These closing means comprise throats (6) located at the edge of the angular areas of the container (1), and intended to cooperate with external flanges (7) of the lid (2).

35 El funcionamiento preciso de los medios de cierre se explica con relación a las figuras 3 y 4, que los muestran con detalle. Así, haciendo referencia a la figura 3, la garganta (6) de aspecto en V de fondo (8) plano, comprende dos incisiones (9, 9'), de las cuales la última citada está localizada al pie de la pared exterior (10) de la garganta (6). The precise operation of the closing means is explained in relation to Figures 3 and 4, which show them in detail. Thus, referring to Figure 3, the throat (6) of flat V-shaped aspect (8), comprises two incisions (9, 9 '), of which the last one mentioned is located at the foot of the outer wall ( 10) of the throat (6).

El reborde externo (7) de la tapa (2) presenta una forma similar, es decir, una forma en V de fondo (12) plano 40 previsto para ser guiado en la garganta (6). La pared exterior (11) de dicho reborde (7) termina en una porción (13) de aspecto paralelo a los fondos (8, 12) respectivamente de la garganta (6) y el reborde (7), así como del recipiente The outer flange (7) of the cover (2) has a similar shape, that is, a flat bottom V shape (12) 40 intended to be guided in the throat (6). The outer wall (11) of said flange (7) ends in a portion (13) of parallel appearance to the bottoms (8, 12) respectively of the throat (6) and the flange (7), as well as of the container

(1) al final de la inserción, en el momento del pinzado. Esta porción (13), que forma una especie de abrazadera exterior, viene a insertarse elásticamente en la incisión 9', terminando por pinzar la tapa (2) en las gargantas (6). (1) at the end of the insertion, at the time of clamping. This portion (13), which forms a kind of outer clamp, is elastically inserted into the incision 9 ', ending by clamping the cover (2) into the throats (6).

45 La existencia de la segunda incisión (9) permite facilitar el pinzado mejorando el acceso al vaciado constituido por la incisión (9'), conduciendo a una especie de apertura favorable a la inserción de la porción externa (13) del reborde 45 The existence of the second incision (9) allows for easier clamping by improving access to the recess constituted by the incision (9 '), leading to a kind of opening favorable to the insertion of the outer portion (13) of the flange

(7) de la tapa (2) en el momento del pinzado. (7) of the cover (2) at the time of clamping.

En la hipótesis representada en las figuras 1 y 2, en el momento del cierre de la tapa (2) sobre el recipiente (1), los 50 rebordes externos (7) de dicha tapa (2) son en un primer tiempo guiados en las gargantas (6) practicadas en los bordes correspondientes de las zonas angulares (4) y (5). In the hypothesis represented in Figures 1 and 2, at the time of closing the lid (2) on the container (1), the 50 external flanges (7) of said lid (2) are initially guided in the throats (6) made on the corresponding edges of the angular zones (4) and (5).

Las dimensiones respectivas de los rebordes (7) y las gargantas (6) permiten una deformación elástica seguida de una liberación de la energía cuando la abrazadera externa (13) llega al nivel de una incisión (9'), realizando el 55 enclavamiento por pinzado. The respective dimensions of the flanges (7) and the throats (6) allow an elastic deformation followed by a release of the energy when the external clamp (13) reaches the level of an incision (9 '), making the interlocking by pinching .

Esto es lo que se representa en la figura 5, en la que el reborde (7) ha sido insertado en la garganta (6), deformando el fondo (8) de ésta que es empujado por el fondo (12) del reborde (7), y después pinzado en la hendidura 9'. La recuperación de forma elástica después del pinzado termina por hacer que la pared exterior (11) del reborde (7) This is what is represented in Figure 5, in which the flange (7) has been inserted into the throat (6), deforming the bottom (8) of it that is pushed by the bottom (12) of the flange (7) ), and then pinched to the 9 'slit. Elastic recovery after clamping ends by causing the outer wall (11) of the flange (7)

60 vuelva a subir a lo largo de la pared exterior (10) de la garganta (6). 60 rise again along the outer wall (10) of the throat (6).

El ejemplo ilustrado por las figuras no es exhaustivo de la invención, que comprende unas variantes de forma, en particular para el par garganta (6)/reborde externo (7), así como la posibilidad de tener únicamente una incisión (9') o incluso un corte más ancho que una simple incisión. The example illustrated by the figures is not exhaustive of the invention, which comprises shape variants, in particular for the throat pair (6) / external flange (7), as well as the possibility of having only one incision (9 ') or even a cut wider than a simple incision.
