OBJECTO DA INVENÇÃO A presente invenção diz respeito a um dispositivo limita dor para roscas de tampas, que foi concebido e realizado para im pedir que a tampa se enrosque alem de limites predeterminados, 0 dispositivo limitador e aplicãvel ao tipo de tampas cons tituTdas por material plástico e que se enroscam num gargalo de garrafas destinadas a conter produtos de preferincia com gases , por exemplo refrescos e similares,OBJECT OF THE INVENTION The present invention relates to a limiting device for screw threads which has been designed and realized to prevent the cap from twisting beyond predetermined limits, the limiting device is applicable to the type of caps made of plastic material and which are screwed onto a bottle neck to contain products preferably with gases, for example soft drinks and the like,
ANTECEDENTES DA INVENÇÃOBACKGROUND OF THE INVENTION
Como atras se expãs, as tampas de material plástico apli^ cãveis em garrafas, quando são utilizadas várias vezes apresentam com demasiada facilidade o inconveniente de, ao exercer-se um esforço moderado de aperto, se vencer a resistência dos fios de ros ca do recipiente e da própria tampa, atingindo-*se o que se denomi^ na "ultrapassagem da rosca", ficando assim a tampa e o recipiente impossibilitados de ser usados, e provocando-se alem disso a fuga do seu conteúdo ou do seu componente gasoso, com as corresponden tes consequências negativas a que isso dã lugar, -As shown in the foregoing, the cylindrical closures of the plastic material in bottles, when used several times, exhibit the disadvantage that by exerting a moderate tightening effort the resistance of the glass wires of the container and of the cap itself, thereby reaching what is referred to as " overrunning the thread ", thereby rendering the cap and container unable to be used, and further causing the leakage of its contents or of its gaseous component , with the corresponding negative consequences to which it gives rise, -
Perante esta problemática estabeleceram-se oportunamente normas de qualidade a que deviam obedecer as tampas deste tipo , determinando essas normas de qualidade os esforços mínimos a que devem resistir todas as tampas aplicadas para obturar recipientes de líquidos.Faced with this problem, quality standards were established in a timely manner, to which the caps of this type should comply, and these quality standards determine the minimum efforts to which all caps applied to fill liquid containers must be resisted.
Ora, devido ã natureza do material -utilizado para a obtenção das tampas, não hi duvida que a determinadas temperaturas podem cumprir-se essas normas de qualidade exigidas, com base num desenho e num dimensionamento concreto da tampa, Porém, acima de uma certa temperatura, e devido ã natureza do material, como se disse, o mesmo esforço suportado anteriormente provocara agora e nessas condições de temperatura mais elevada, a passagem da rosca.Due to the nature of the material used to obtain the lids, it is not doubtful that at certain temperatures the required quality standards can be met, on the basis of a design and a particular design of the lid. However, above a certain temperature , and because of the nature of the material, as has been said, the same previously supported stress would now have caused the thread to pass through these higher temperature conditions.
Por isso, os fabricantes de tampas ficam obrigados a so-bredimensionar o conjunto com os inconvenientes técnicos e econo micos que isso acarreta,Hence, manufacturers of lids are obliged to resize the whole with the technical and economic drawbacks that this entails,
DESCRIÇÃO DA INVENÇÃO A tampa segundo a presente invenção ê do tipo descrito , mas incorpora um dispositivo de espera para solucionar definitivamente os problemas e os inconvenientes atras referidos, tudo isso a fim de a temperatura não influir .na maior ou menor 'eficiência do sistema.DESCRIPTION OF THE INVENTION The cap according to the present invention is of the type described, but incorporates a holding device to definitively solve the above-mentioned problems and drawbacks, all so that the temperature does not influence, to a greater or lesser extent, the efficiency of the system.
Nesse sentido, a espera incorporada na tampa fica dispôs ta na passagem da rosca do gargalo do recipiente, impedindo que -3-In that sense, the catch incorporated in the closure is disposed in the passageway of the neck of the container neck, preventing -3-
a dita tampa continue a enroscar-se antes de se atingir um esfor ço exagerado lateral nos fios de rosca. 0 referido dispositivo de espera, como foi mencionado, e aplicável a tampas de material plástico, mais concretamente ás que apresentam um corpo em forma de capuz com rosca interior para o seu acoplamento com a rosca interior do recipiente, com a particularidade de esse capuz estar convencionalmente provido no seu bordo inferior com o respectivo anel de precinta, incluindo esta um dente para se encaixar numa nervura transversal do recipiente .said cap continues to coil prior to reaching an exaggerated lateral effort on the threads. Said holding device, as has been mentioned, is applicable to plastic caps, more specifically those having a hood-shaped body with internal thread for coupling with the internal thread of the container, with the particularity of said hood being conventionally provided on its lower edge with the respective strap ring, this latter including a tooth for engaging a transverse rib of the container.
Igualmente, esta tampa apresenta uma pestana anular interior ou tabique para o seu ajustamento na boca do recipiente , isto e, o bordo superior da garrafa fica intercalado entre essa pestana ou tabique concêntrico e a superfície lateral da tampa.Also, this cap has an inner annular flange or septum for adjustment into the mouth of the container, i.e., the upper edge of the bottle is sandwiched between that concentric flange or partition and the side surface of the cap.
No que respeita ao dispositivo de espera propriamente dj[ to, o mesmo e constituído por um engrossamento situado no contor^ no do capuz, de preferência em correspondência com a aresta interior estabelecida entre o fundo e a saia ou pestana interior do referido capuz, tudo isso para que o engrossamento fique colocado na passagem do primeiro troço de rosca do gargalo do recipiente, determinando um obstáculo resistente à rotação da tam pa na ultima fase do enroscamento.With respect to the holding device itself, it is formed by a thickening situated in the hood contour, preferably in correspondence with the inner edge established between the bottom and the inner skirt or eyelash of said hood, all so that the thickening is placed in the passageway of the first thread portion of the container neck, determining an obstacle resistant to the rotation of the tampon in the last phase of the screwing.
De preferência, a espera abrange um arco de cerca de 75QC e o seu raio interior deve ser menor do que metade do diâmetro exterior da rosca do gargalo do recipiente. -4-Preferably, the wait encompasses an arc of about 75øC and its inner radius should be less than half the outer diameter of the thread of the container neck. -4-
Para complementar a descrição que vai seguir-se e para ajudar a melhor compreender as características da presente inveji ção apresentam-se em anexo desenhos com base nos quais podem com preender-se melhor as característieas do objecto da presente invenção .In order to complement the description which is to be followed and to help better understand the features of the present invention, there are attached drawings on the basis of which the features of the subject of the present invention may be better understood.

DESCRIÇÃO DA FORMA DE REAUZAçÃQ PREFERIDADESCRIPTION OF PREFERRED EMBODIMENT
Observando as figuras, pode ver-se que o.dispositivo de espera segundo a presente invenção pode ser aplicado a tampas (1) de material plástico destinadas a aplicar-se, por enroscamen to, no filete correspondente (2) previsto no gargalo de um recipiente (3), destinando-se este ultimo a conter produtos líquidos, por exemplo refrescos ou similares. -5-In view of the figures, it can be seen that the holding device according to the present invention can be applied to covers (1) of plastics material intended to be screwed onto the corresponding thread (2) provided on the neck of a (3), the latter being intended to contain liquid products, for example soft drinks or the like. -5-
A tampa (1), que tem a forma de um capuz, e convenciona]_ mente completada, em correspondência com o seu bordo inferior . com um anel de precinta (4) dotado de um dente anular (5) destinado a encravar-se na nervura transversal (6) do recipiente (3), enquanto no fundo do conjunto se previu uma saia ou tabique concêntrica (7) entre a qual e a superfTcie lateral inferior do capuz (1) se encaixa o bordo superior do gargalo do recipiente (3). 0 dispositivo de espera ê constituído por uma grossura (8) prevista em correspondência com o contorno do capuz (1), de preferência na aresta interior estabelecida entre o fundo e a saia ou tabique concêntricos (7), como se vê perfeitamente na pa_r te da esquerda das fig. 1 e 2.The cap (1), which has the form of a hood, is conventionally completed in correspondence with its lower edge. with a strap ring (4) provided with an annular tooth (5) for engaging the transverse rib (6) of the container (3), while at the bottom of the assembly a concentric skirt (7) has been provided between the and the lower side surface of the hood (1) engages the upper edge of the container neck (3). The holding device is constituted by a thickness (8) provided in correspondence with the contour of the hood (1), preferably at the inner edge established between the bottom and the concentric skirt (7), as can be seen perfectly in the case from the left of fig. 1 and 2.
Essa grossura (8) dispõe-se na passagem do primeiro tr£ ço (2') da rosca (2) do gargalo do recipiente (3), determinando um obstáculo resistente á rotação da tampa na última fase do en roscamento, abrangendo alem disso essa grossura (8) um arco de cerca de 75°C e apresentando um raio interior menor do que meta de do diâmetro exterior da rosca (2) do gargalo do recipiente (3).This thickness (8) is provided in the passage of the first thread (2 ') of the thread (2) of the neck of the container (3), determining an obstacle resistant to rotation of the cap in the last phase of threading, (8) having an arc of about 75 ° C and having an inner radius smaller than that of the outer diameter of the thread (2) of the neck of the container (3).
Deste modo, quando se. enrosca a tampa (1) no gargalo do recipiente (3), atingir-se-ã um ponto em que o primeiro troço de rosca (2') se encontrara com a grossura (8), dificultando o seu avanço ate chegar a uma resistência tal que o esforço nece^s sario para continuar a rodar manualmente a tampa ultrapassa o estabelecido como norma de segurança.Thus, when. (1) into the neck of the container (3), a point will reach at which the first thread (2 ') meets the thickness (8), making it difficult to advance until a resistance such that the effort required to continue to manually turn the cap exceeds that established as a safety standard.
Logicamente, o dito esforço e suportado unicamente pela -6*Logically, the said effort is only supported by -6 *
grossura (8) e por esse primeiro troço (2') da rosca (2) corres pondente do recipiente (3), tudo de modo tal que os fios de ro£ ca do recipiente e certamente os da tampa não sofrerão qualquer sobretensão lateral, conseguindo-se assim uma duração indefení-da do fecho da tampa e uma garantia de conservação dol Tquido contido, evitando-se também qualquer risco de fuga.(8) and that first section (2 ') of the corresponding thread (2) of the container (3), all in such a way that the roving threads of the container and certainly those of the cap will not suffer any lateral overvoltage, thereby achieving an indefinite life of the closure of the lid and a guarantee of preservation of the contained liquid, also avoiding any risk of leakage.
