Description

Cierre para tarro de boca ancha. Closure for wide mouth jar.

5 Object of the invention

La presente invención se refiere a un cierre para un tarro de boca ancha, que comprende una tapa a presión provista de un cierre estanco, aún después de haber abierto por primera vez el envase y retirado el precinto de cierre. The present invention relates to a closure for a wide-mouth jar, comprising a pressure lid provided with a tight seal, even after the container has been opened for the first time and the seal has been removed.

Background of the invention

Los tarros generalmente están provistos de una boca de suficiente diámetro que permita la cómoda extracción del producto. Sobre la boca ajusta una tapa de cierre The jars are generally provided with a mouth of sufficient diameter that allows the comfortable extraction of the product. Over the mouth adjusts a closure cap

Actualmente muchos de los cierres para envases de este tipo consisten en una tapa de cierre a presión, que originalmente está provista de una zona inferior rasgable, que constituyen un precinto que garantiza la inviolabilidad del envase hasta que el consumidor independiza la parte tapa respecto del anillo-precinto. 15 that is threaded or pressurized. Currently, many of the closures for containers of this type consist of a snap closure lid, which is originally provided with a tear-off bottom, which constitutes a seal that guarantees the inviolability of the container until the consumer makes the lid part independent of the ring. -seal.

20 El cierre a presión de la tapa se efectúa por medio de un nervio interior que ajusta sobre un resalte periférico exterior moldeado en la boca del envase. Este nervio está presente en el collarín, que está unido a su vez al cuerpo de la tapa mediante una zona rasgable, que permite separar el collarín inferior del cuerpo de la tapa. En consecuencia, una vez abierto el envase, la tapa escasamente ajusta sobre el cuello o 20 Pressing the lid is closed by means of an inner rib that fits over an outer peripheral shoulder molded into the mouth of the container. This nerve is present in the collar, which in turn is attached to the body of the lid by a tear-off zone, which allows the lower collar to be separated from the body of the lid. Consequently, once the container is opened, the lid barely fits over the neck or

Description of the invention

30 La invención mejora la técnica actual en cuanto que prevé la posibilidad de efectuar un cierre estanco, aún después de haber abierto por primera vez el envase y retirado el precinto de cierre. Para ello se ha mejorado la tapa para lograr su adaptación al cuello del envase, dotándola de un obturador formado por por dos paredes flexibles entre sí The invention improves the current technique insofar as it provides for the possibility of carrying out a tight seal, even after the container has been opened for the first time and the seal has been removed. To this end, the lid has been improved to adapt to the neck of the container, providing it with a shutter formed by two flexible walls.

35 que forman un canal periférico por la cara interior del envase, que tiende a adaptarse a él al presionar la tapa contra el borde del envase por efecto de la presión interna del mismo. 35 which form a peripheral channel through the inner face of the container, which tends to adapt to it by pressing the lid against the edge of the container due to the internal pressure thereof.

Por otro lado se ha dispuesto un doble enganche de retención para impedir que la tapa On the other hand, a double retention hitch has been arranged to prevent the lid

5 se salga de la boca como sucede en la mayoría de los cierres del mercado que solo tienen un enganche de retención en la zona del collarín asociado inicialmente a la tapa. En nuestro caso el propio cuerpo de la tapa dispone de un primer enganche de retención, mientras que el segundo está situado en el collarín, de forma que una vez abierta la tapa por la zona de rasgado es posible tapar nuevamente el envase 5 out of the mouth as in most market closures that only they have a retention hitch in the area of the collar initially associated with the top. In our case the body of the lid itself has a first coupling of retention, while the second is located on the collar, so that once open the lid through the tearing area it is possible to cover the container again

35 línea de rotura (24), que se desprende cuando la tapa se abre por primera vez. 35 break line (24), which comes off when the lid is first opened.

El envase (1) dispone de otros dos resaltes (11) y (12) que cumplen una importante función en este tipo de cierre, como es la establecer un doble cierre, que una vez abierta la tapa por primera vez queda reducido a uno solo, pero con plenas garantías de hermeticidad. The package (1) has two other projections (11) and (12) that play an important role in this type of closure, such as establishing a double closure, which once opened the lid for the first time is reduced to one , but with full guarantees of tightness.

Por su parte la tapa (2) presenta un disco superior (2) ligeramente abombado hacia fuera y rehundido con respecto al borde periférico (21) de la tapa, que se prolonga formando un anillo envolvente que dispone interiormente de un nervio (26) el cual va a encajar en el primer resalte (11) situado próximo a la boca del tarro (1). La tapa (2) 10 define también superiormente un canal interior (23) flexible, próximo a la periferia y que alcanza por debajo del primer nervio de retención (26), conformando un mecanismo de obturación que presiona esta zona de la tapa (2) contra el borde del envase (1) por efecto de la presión interna del envase, manteniendo la hermeticidad del envase aún cuando únicamente está cerrada la tapa por el enganche de retención On the other hand, the cover (2) has an upper disc (2) slightly bulged outwards and recessed with respect to the peripheral edge (21) of the cover, which extends forming an enveloping ring that internally has a rib (26) the which will fit the first projection (11) located near the mouth of the jar (1). The cover (2) 10 also defines superiorly a flexible inner channel (23), close to the periphery and which reaches below the first retention rib (26), forming a sealing mechanism that presses this area of the cover (2) against the edge of the container (1) due to the internal pressure of the container, maintaining the tightness of the container even when only the lid is closed by the retention hitch
