Description

Objeto de la invención Object of the invention

5 El modelo de utilidad que se presenta tiene por objeto una cuchara doble que por sus características, conformación y uso complementa de forma notable los múltiples tipos de cucharas existentes en el mercado y que forman parte del estado de la técnica. 5 The purpose of this utility model is to have a double spoon that, due to its characteristics, shape and use, notably complements the multiple types of spoons existing in the market and that are part of the state of the art.

En concreto, esta innovación se refiere a una cuchara conformada en base a una doble Specifically, this innovation refers to a spoon shaped based on a double

10 concavidad situada cada una en extremos opuestos y conectadas mediante un canal que las comunica, de tal modo que el caldo o salsa puede pasar de una a otra concavidad. Gracias a esta conformación, se consigue garantizar la máxima higiene y salubridad del alimento que se cocina puesto que sólo se introduce en el recipiente una de las concavidades y se reserva la segunda concavidad para el taste del cocinero. 10 concavity each located at opposite ends and connected by a channel that communicates them, so that the broth or sauce can pass from one concavity to another. Thanks to this conformation, it is possible to guarantee maximum hygiene and healthiness of the food that is cooked since only one of the concavities is introduced into the container and the second concavity is reserved for the chef's taste.

Estado de la técnica State of the art

Es obvio que la cuchara es uno de los utensilios de mayor uso desde tiempos inmemoriales, usado tanto para comer como para servir alimentos líquidos o pastosos. A It is obvious that the spoon is one of the most used utensils since time immemorial, used both for eating and serving liquid or pasty foods. TO

20 lo largo de la historia se ha ido modificando su diseño, en especial su cabezal, con una concavidad variable, y manteniéndolo, en cualquier caso, vinculado a un mango también de longitud y grosor variable para manipular tal utensilio. 20 throughout history its design has been modified, especially its head, with a variable concavity, and maintaining it, in any case, linked to a handle also of variable length and thickness to manipulate such a utensil.

En la actualidad coexisten diversos tipos de cuchara destinadas a usos distintos y/o At present, several types of spoon coexist for different uses and / or

25 complementarios en el ámbito culinario. Existe, por ejemplo, una cuchara que comprende un cabezal provisto de perforaciones pasantes en toda o parte de su superficie, lo que permite eliminar parte del caldo y degustar mayor cantidad de pasta. También se ha diseñado un tipo de utensilio que comprende un único mango con dos cabezales distintos, por ejemplo en un extremo un cabezal típico de cuchara y en el otro extremo del mango un 25 complementary in the culinary field. There is, for example, a spoon comprising a head provided with through holes in all or part of its surface, which allows removing part of the broth and tasting more pasta. A type of utensil has also been designed comprising a single handle with two different heads, for example at one end a typical spoon head and at the other end of the handle a

30 cabezal plano tipo espátula. Y el mismo principio de mango único se aplica a un utensilio con dos cabezales extremos del tipo cuchara, siendo dichos cabezales de concavidades dimensionalmente distintas, con lo que se obtiene una cuchara medidora con concavidades de capacidad tipo te y sopera. 30 spatula type flat head. And the same principle of single handle is applied to a utensil with two end heads of the spoon type, said heads being dimensionally different concavities, whereby a measuring spoon with concavities of tea and soup capacity is obtained.

35 A nivel de propiedad industrial, existen varias propuestas de cuchara, como es el modelo de utilidad 128212 referido a un cubierto de campaña que presenta un utensilio que comprende cuchara, tenedor y cuchillo acoplables entre sí. El modelo de utilidad U 9801423 se refiere a una cuchara plegable con una estructura abatible de dos mitades, de modo que se pliega ocupando aproximadamente la mitad de espacio que una cuchara convencional. Por su parte el modelo de utilidad U 201001240 presenta una cucharilla enrollable diseñada para poder ir incluida en el envase habitual de productos alimenticios y que consiste en una cucharilla plana, flexible y de poco espesor y que recupera su rigidez mediante la curvatura de su superficie, cambiando de una superficie plana a una cóncava. La patente europea 91112969.0 desarrolla una cuchara de cocina diseñada especialmente para remover productos cocinados y que comprende un mango y un elemento de paleta, que utiliza alambre envolvente para mejorar su conformación y uso. 35 At the level of industrial property, there are several spoon proposals, such as utility model 128212 referring to a campaign cover that presents a utensil comprising spoon, fork and knife that can be attached to each other. Utility model U 9801423 refers to a folding spoon with a folding structure of two halves, so that it folds occupying approximately half the space of a conventional spoon. On the other hand, the utility model U 201001240 has a rolling spoon designed to be included in the usual container of foodstuffs and consisting of a flat, flexible and low-thickness spoon that recovers its rigidity through the curvature of its surface, changing from a flat surface to a concave. European Patent 91112969.0 develops a kitchen spoon specially designed to remove cooked products and comprising a handle and a vane element, which uses wrap wire to improve its conformation and use.

Estos y otros muchos utensilios que incluyen una concavidad tipo cuchara son perfectamente funcionales en su uso pero en el ámbito de la cocina, tanto si es profesional como domestica, se evidencia un hecho que cuestiona la eficacia de las cucharas. Es un hecho muy simple, conocido y habitual: se utilizan cucharas para remover y probar la comida en cocción. La práctica habitual del cocinero es introducir la cuchara en la cazuela, recoger una porción de salsa, caldo o jugo y llevarla a la boca para probar su sabor y rectificar condimentos o sal. Y como esa práctica se repite varias veces durante la cocción, la cuchara pasa repetidas veces de la cazuela a la boca y de la boca a la cazuela. These and many other utensils that include a concavity type spoon are perfectly functional in their use but in the field of cooking, whether it is professional or domestic, there is evidence of a fact that questions the effectiveness of the spoons. It is a very simple, known and usual fact: spoons are used to stir and taste the cooking food. The usual practice of the cook is to introduce the spoon in the casserole, pick up a portion of sauce, broth or juice and bring it to the mouth to taste it and rectify seasonings or salt. And as this practice is repeated several times during cooking, the spoon passes repeatedly from the casserole to the mouth and from the mouth to the casserole.

Evidentemente, la higiene que ello comporta es muy cuestionable puesto que la cuchara en cuestión es portadora inevitable de microorganismos y/o secreciones provenientes del cocinero y que, al introducir de nuevo la cuchara en el recipiente, se transmiten a la comida. Obviously, the hygiene that this entails is very questionable since the spoon in question is an inevitable carrier of microorganisms and / or secretions from the cook and that, when the spoon is introduced back into the container, they are transmitted to the food.

El solicitante de este modelo de utilidad entiende que debería existir una cuchara sustancialmente distinta, destinada a ser utilizada durante la cocción de guisos, sopas y en general todo tipo de platos en los que intervienen salsas, caldos o jugos que el cocinero tiende a probar para verificar el sabor, el punto de condimento o de sal, etc. y que dicha cuchara garantizara la máxima salubridad de la comida. The applicant of this utility model understands that there should be a substantially different spoon, intended to be used during the cooking of stews, soups and in general all kinds of dishes in which sauces, broths or juices that the cook tends to try to verify flavor, seasoning or salt, etc. and that said spoon will guarantee maximum healthiness of the food.

Descripción de la invención Description of the invention

Así pues, el objeto de este modelo de utilidad es una cuchara doble que tiene por objetivo garantizar la máxima higiene en la preparación de comidas y se concibe como un utensilio especialmente diseñado para probar la comida que se está cocinando, en particular salsas, caldos y jugos que tienen una consistencia esencialmente líquida. Thus, the purpose of this utility model is a double spoon that aims to ensure maximum hygiene in the preparation of meals and is conceived as a utensil specially designed to taste the food being cooked, in particular sauces, broths and juices that have an essentially liquid consistency.

Este utensilio está conformado por dos concavidades extremas, de igual o diferente tamaño y/o capacidad, vinculadas por una varilla acanalada a modo de brazo de unión y que permite que el contenido de una concavidad pase a la otra concavidad. This utensil is made up of two extreme concavities, of equal or different size and / or capacity, linked by a ribbed rod as a connecting arm and that allows the contents of one concavity to pass to the other concavity.

Su uso es intuitivo y simple: una de las concavidades se utiliza únicamente para introducirse en el recipiente en que se cocina la comida mientras que la segunda concavidad es la que el usuario se lleva a la boca para probar dicha comida, de forma que se garantiza la máxima salubridad y cuidado de la comida sin riesgo de contaminarla por el contacto con la boca del cocinero. Its use is intuitive and simple: one of the concavities is only used to enter the container in which the food is cooked while the second concavity is the one that the user takes to the mouth to taste said food, so that it is guaranteed maximum health and care of food without risk of contaminating it by contact with the cook's mouth.

La cuchara doble que se reivindica está, pues, conformada por dos concavidades extremas comunicadas por una varilla acanalada, la cual es susceptible de estar descubierta o bien estar cubierta. The double spoon that is claimed is thus made up of two extreme concavities communicated by a ribbed rod, which is likely to be uncovered or covered.

En este segundo caso, la cubierta es susceptible de ser fija, es decir, que el canal se conforme a modo de tubo o cañería, aunque ello puede conllevar un problema de limpieza al ser un espacio excesivamente cerrado. In this second case, the cover is capable of being fixed, that is, that the channel conforms to a pipe or pipe mode, although this can lead to a cleaning problem as it is an excessively enclosed space.

Una segunda conformación de la varilla acanalada cubierta se concibe con una tapa desplazable, sea una tapa continua que cubra toda la longitud de la varilla o bien una tapa fraccionada de uno o más tramos, conformando de este modo un conducto. En ambos casos, se plantean diversas resoluciones técnicas para vincular la varilla acanalada con la tapa. A second conformation of the covered ribbed rod is conceived with a movable cover, either a continuous cover that covers the entire length of the rod or a fractional cover of one or more sections, thereby forming a conduit. In both cases, various technical resolutions are proposed to link the ribbed rod with the lid.

Una primera opción es vincular la varilla acanalada con la tapa mediante un sistema de articulación del tipo bisagra o similar. Esta solución facilita la unidad de ambas piezas, se evita el riesgo de extravío de la tapa y se facilita la producción en base a un molde único. A first option is to link the ribbed rod with the lid by means of a hinge type articulation system or similar. This solution facilitates the unity of both pieces, the risk of loss of the lid is avoided and production based on a single mold is facilitated.

Una segunda opción es diseñar una tapa independiente que se vincula a la varilla acanalada con sujeción mediante ranuras de ajuste del tipo clik-clak, a presión o por sistemas machiembrados. A second option is to design an independent cover that links to the ribbed rod with clamping by means of adjustment grooves of the clik-clak type, by pressure or by tongue-and-groove systems.

La disposición posicional entre ambas piezas (varilla acanalada y tapa desplazable) mantiene siempre la varilla acanalada en un plano inferior y la tapa desplazable en un plano superior y en base a ello se pueden establecer tres variantes. Una primera variante contempla la tapa desplazable con un diámetro menor que la varilla acanalada, por lo que encaja en las paredes interiores de la varilla acanalada. Una segunda variante contempla la tapa desplazable con un diámetro mayor que la varilla acanalada, por lo que queda encajada sobre las paredes exteriores de la varilla acanalada. Una tercera variante contempla ambas partes, tapa y varilla acanalada, de igual diámetro, con lo que ambas partes encajan una sobre otra y se apoyan en sus respectivos bordes, The positional arrangement between the two pieces (ribbed rod and movable lid) always keeps the ribbed rod in a lower plane and the movable lid in an upper plane and based on this three variants can be established. A first variant contemplates the movable cover with a diameter smaller than the ribbed rod, so it fits into the inner walls of the ribbed rod. A second variant contemplates the movable cover with a diameter greater than the ribbed rod, so that it is embedded on the outer walls of the ribbed rod. A third variant contemplates both parts, cover and ribbed rod, of equal diameter, whereby both parts fit over each other and rest on their respective edges,

Respecto a las concavidades propiamente dichas y situadas en los extremos de la varilla acanalada, la conformación básica de la cuchara doble que se reivindica prevé que dichas concavidades sean fijas, es decir, formen un cuerpo único con la varilla que las vincula, Sin embargo, es igualmente viable que una o ambas concavidades sean extraíbles y ajustables mediante distintas forma de acople: rosca, machihembrado, etc. Esta solución técnica permite cambiar una, otra o ambas concavidades, sea por motivos estrictamente prácticos como pueda ser combinar tamaños de concavidades distintos o sea por motivos estéticos para combinar piezas de diseños diferentes. Esta opción es especialmente interesante si se plantea la cuchara doble reivindicada como un utensilio culinario y a la vez como un artículo promocional, merchandising, reclamo turístico, etc. With respect to the concavities proper and located at the ends of the ribbed rod, the basic conformation of the double spoon that is claimed provides that said concavities are fixed, that is, they form a single body with the connecting rod, however, It is equally feasible that one or both concavities are removable and adjustable through different forms of coupling: thread, tongue and groove, etc. This technical solution allows changing one, another or both concavities, either for strictly practical reasons such as combining different sizes of concavities or for aesthetic reasons to combine pieces of different designs. This option is especially interesting if you consider the double spoon claimed as a culinary utensil and at the same time as a promotional item, merchandising, tourist claim, etc.

A partir de esta conformación base, la cuchara doble que se reivindica es susceptible de incorporar al menos un elemento de agarre destinado a facilitar su manipulación, como por ejemplo al menos una aleta lateral que se proyecta desde algún punto de la varilla acanalada o bien al menos un saliente de agarre situado en uno o ambos cabezales. From this base conformation, the claimed double spoon is capable of incorporating at least one gripping element intended to facilitate its handling, such as at least one lateral fin projecting from some point of the ribbed rod or to the less a grip projection located on one or both heads.

Descripción de una realización preferida Description of a preferred embodiment

En las figuras 1, 2 y 3 que acompañan a esta memoria se describe el objeto de esta invención, concretado en una cuchara doble conformada por dos concavidades (1) y (2) extremas, de igual o diferente tamaño y/o capacidad, vinculadas por un brazo a modo de varilla acanalada (3) susceptible de quedar cubierta, conformada a modo tubo o cañería o bien contar con una tapa o cubierta desplazable (4), tal y como se muestra en la figura 3. In figures 1, 2 and 3 accompanying this report the object of this invention is described, concretized in a double spoon formed by two extreme concavities (1) and (2), of equal or different size and / or capacity, linked by an arm as a ribbed rod (3) capable of being covered, shaped as a pipe or pipe or have a cover or movable cover (4), as shown in Figure 3.

En las figuras 4, 5 y 6 se muestra la disposición posicional de la varilla acanalada (3) y la tapa desplazable (4). De acuerdo con estas figuras y con lo ya expuesto en esta descripción, la varilla acanalada (3), que actúa como nexo de unión entre las dos concavidades (1) y (2), queda situada siempre en un plano inferior mientras que la cubierta Figures 4, 5 and 6 show the positional arrangement of the ribbed rod (3) and the movable cover (4). In accordance with these figures and with what is already stated in this description, the ribbed rod (3), which acts as a link between the two concavities (1) and (2), is always located in a lower plane while the cover

: o tapa desplazable (4) queda situada en un plano superior cubriendo dicha varilla acanalada (3). or movable cover (4) is located in an upper plane covering said ribbed rod (3).

En una realización básica, especialmente concebida para abaratar costes en la fabricación de la cuchara que se reivindica, se entiende, tal y como se muestra en la figura 4 que ambas partes, es decir, la varilla acanalada (3) y la cubierta o tapa desplazable (4), tengan diámetros idénticos al objeto de que, una vez superpuestas una sobre otra, tengan un ajuste correcto, estando vinculadas ambas piezas, en su caso, con una bisagra (5), nervio In a basic embodiment, especially designed to reduce costs in the manufacture of the claimed spoon, it is understood, as shown in Figure 4 that both parts, that is, the ribbed rod (3) and the cover or lid movable (4), have identical diameters in order that, once superimposed on one another, they have a correct adjustment, both pieces being linked, where appropriate, with a hinge (5), nerve

: o similar y/o contando con al menos un medio mecánico de cierre (6) que asegure el cierre del canal que ambas piezas conforman. or similar and / or with at least one mechanical means of closure (6) that ensures the closure of the channel that both pieces make up.

Sin embargo, a efectos de realización práctica, es igualmente viable y funcional que la cubierta o tapa desplazable (4) sea una pieza independiente, físicamente separada de la varilla acanalada (3), presente un diámetro menor y quede encajada y afirmada en las paredes interiores de la varilla acanalada (3), tal como se muestra en el esquema de la figura 5, o bien que dicha cubierta o tapa desplazable (4) presente un diámetro mayor, con lo que dicha pieza queda encajada sobre las paredes exteriores de la varilla acanalada (3), tal como se muestra en el esquema de la figura 6. En ambos casos, el ajuste de ambas partes es susceptible de contar con un medio mecánico para afirmar y asegurar el encaje. However, for practical purposes, it is equally viable and functional that the movable cover or cover (4) is an independent piece, physically separated from the ribbed rod (3), has a smaller diameter and is embedded and secured in the walls interiors of the ribbed rod (3), as shown in the scheme of figure 5, or that said movable cover or cover (4) has a larger diameter, whereby said piece is fitted on the outer walls of the Ribbed rod (3), as shown in the diagram in Figure 6. In both cases, the adjustment of both parts is capable of having a mechanical means to secure and secure the fit.

A la vista de estos dibujos y de la descripción anterior resultan evidentes las ventajas de la nueva cuchara doble. In view of these drawings and the above description, the advantages of the new double spoon are evident.

En cuanto a su uso, es el único utensilio culinario que permite probar el sabor y/o estado de caldos, salsas y jugos de una forma higiénica y sin riesgo de contaminarlo puesto que la concavidad extrema de la cuchara que está en contacto con la boca del cocinero nunca está dentro del recipiente y en contacto con los alimentos, de igual modo que la concavidad extrema de la cuchara que sí está dentro del recipiente nunca llega a la boca del usuario. As for its use, it is the only culinary utensil that allows you to test the taste and / or condition of broths, sauces and juices in a hygienic way and without risk of contaminating it since the extreme concavity of the spoon that is in contact with the mouth The chef is never inside the container and in contact with food, just as the extreme concavity of the spoon that is inside the container never reaches the user's mouth.

En cuanto a su conformación, la posibilidad de tener cavidades recambiables permite combinar tanto tamaños como diseños, lo que abre una vía de negocio interesante en el campo del menaje culinario, como artículo promocional e incluso como objeto decorativo. En este sentido es importante señalar que una o ambas concavidades extremas combinan en su conformación formas y líneas caprichosas, creando diseños y figuras que imiten y/o asemejen lugares, objetos, monumentos, etc. Regarding its conformation, the possibility of having replaceable cavities allows combining both sizes and designs, which opens an interesting business path in the field of culinary utensils, as a promotional item and even as a decorative object. In this sense it is important to point out that one or both extreme concavities combine capricious shapes and lines in their conformation, creating designs and figures that mimic and / or resemble places, objects, monuments, etc.

En cuanto a su fabricación, la cuchara doble es susceptible de fabricarse en una gran diversidad de materiales: acero, aluminio, PVC, madera y cualquier otro sin ver alterada ni su conformación ni su uso. As for its manufacture, the double spoon is capable of being manufactured in a wide variety of materials: steel, aluminum, PVC, wood and any other without seeing its shape or use altered.

No se considera necesario hacer más extensa esta descripción para que cualquier experto en la materia comprenda el alcance de la invención y las ventajas que de la misma se derivan.
