Hermetic sealing system for containers

Abstract

A system includes a lid that moves in a plane parallel to the mouth of a container, a mechanism for activating the lid between the open and closed positions, and a pneumatic seal that acts on the surfaces opposite the lid, and the mouth in the closed position. The mouth has a ring that protrudes laterally from the mouth. The ring and the lid are equipped with an upper latch and a lower latch to hold the lid in the closed position. The pneumatic seal has an elastic protective cover and the mechanism for activating the lid are linked to a remote control device.

Description

[0001]The present invention relates to a hermetic sealing system for fixed or unfixed containers for all types of products, in which pressure may or may not intervene. The tubular configuration of the container coupling flange, allows exchanging this system for those currently used in containers. The modular design of each element permits the exchange of coupling means required for each type of mouth depending on the product being handled. The fastening system of the sealing together with the pneumatic system, which ensures the tightness of the assembly, allow the effect of pressure inside the container to not affect the sealing thereof.

Problems solved by technology

The fact that the mouths of the containers are located at the top and very often on curved metallic surfaces (frequently wet), can cause serious accidents during the loading / unloading process, since this implies that an operator must access them and manually perform the opening and closing maneuver.

Access to it, apart from the difficulty due to its height, involves the placement of an access element (stairs in most cases) that in certain circumstances is both an additional risk as well as an additional cost for the equipment.

There are currently opening and closing systems, using a large screw that is manually operated by a lever, both tighten the closing lid over the mouth, with the risk (which has caused numerous accidents) of the wear of the thread rib either by the use or by rests of filling products being deposited, causing wear on the system and its random detachment, especially in those containers to which an inner pressure is applied to discharge the product quickly and effectively.

This manual system requires the operator to maneuver on high, uneven (spherical) and sliding (moisture, product residues) surfaces, so that the force created from closing it presents a high probability of accidents.

Furthermore, between the joints and the lid there must be a certain tolerance so said joint permits displacement of the lid, thus these systems do not ensure total sealing of the closure and are not effective in those cases in which pressure is applied inside the container during product discharge operations.

In the cited background, the lid requires a certain clearance for opening and closing, which determines a certain mobility of the lid when using a static rubber gasket and a lack of tightness in the sealing and, in case of using a pneumatic seal, force must be transmitted to the lid and its guide means, which causes misalignment of the lid.
