Description

VENTILATION COVER AND CONTAINER WITH SAID VENTILATION COVER DESCRIPTIVE MEMORY The present invention relates to a pressure release container with a discharge port opening, a neck along the periy of the discharge port opening, and a ventilation cover comprising a body plate for covering the discharge port opening, the body plate has a ventilation opening and along its periy a flange is provided with an inner perial surface provided with holding means for cooperating with the corresponding securing means on the outer face of the neck, wherein the ventilation opening is covered by a gas permeable filter. Such containers can normally be used for compositions that are susceptible to exothermic decomposition. Due to this slow decomposition with emanation of a gas that is able to create, over time, a dangerous overpressure in the container, said compositions can not be kept in hermetically sealed containers. Among these materials are the peroxide formulations, optionally dissolved in the phlegmatizing flame, usually hydrocarbon solvents, or in aqueous solutions, emulsions or suspensions. Typical examples of said peroxide materials are the hydrogen peroxide or mineral peroxides such as aqueous solutions of monoperoxysulfuric acid or liquid organic peroxides. All these peroxides are permanently releasing small amounts of gas, such as oxygen. To avoid dangerous overpressures in the containers of these products, these containers are provided with porous filters that are gas permeable and that are hermetic in regard to liquids. Passing the filter, the gases are discharged through one or more openings in a closing lid. The document E.U.A. No. 4,853,013 discloses a vent cover with a filter structure for a container that may contain hazardous materials such as liquid organic peroxides. It contains a lid and a filter structure. During normal operation, the gas released by the liquid in the container passes through the entire filtering structure and escapes through the ventilation means. The filter structure contains two filters that are gas permeable and liquid impervious. Said ventilation systems have a rather complicated structure and therefore its manufacture is expensive. AU 9 341 259 discloses pressure ventilation for the storage and transport of, for example, organic peroxides in the form of a lid with a small hole which is occluded by a porous PTFE membrane in intimate contact with a layer of a porous polyethylene foam.
In EP 0 759 401 A, PTFE filters are described in ventilation covers of screw caps. The object of the invention is to provide a ventilation system having a simplified construction, which is particularly suitable for storing peroxide formulations or other materials that are susceptible to exothermic decomposition. The object of the invention is achieved with a container according to the initial paragraph, characterized in that the gas permeable filter is a sheet that is fixed between the means for fastening the neck and the flange. In this way a very effective ventilation construction can be obtained at low cost, which can be easily assembled. The sheet can be, for example, a sheet of a plastic material, such as low density or high density polyethylene (LDPE, HDPE), polyvinyl chloride, polypropylene or the like. The thickness of the sheet can be, for example, between about 5 microns and about 0.5 mm, for example between about 10 microns and about 0.1 mm. To make the sheet permeable to gases, for example, the sheet can be punched. The pore diameter of the perforations can be, for example, between about 10 microns and about 2 mm, for example, between about 0.1 mm and about 1.5 mm. To prevent spillage of the contents, the permeable sheet may be constructed, for example, with two or more layers of perforated sheet. From Preferably, these are installed in such a way that the perforations of one layer are not aligned with the perforations of the other layer. The perforation cover can be, for example, a screw cap. For this purpose, the aforementioned fastening means can be formed by an external thread on the outer surface of the neck of the discharge opening, and a corresponding internal thread in the flange of the perforation cover. Other fastening systems can also be used, such as for example press fit connections or clamp connections. Optionally, the ventilation opening in the ventilation cover is provided with a trigger cover. To this end, the ventilation opening may be surrounded by a neck that closely fits into a peripheral flange of the firing cap, wherein the sides facing each other of the neck and the flange are profiled to form a union by releasable pressure. This profiling may include mutually cooperating seams and gaps as is commonly used in the field of pressure-bonding technology, this allows the pressure joint to be dimensioned in such a way that it will leak some predetermined overpressure, for example, a pressure in the scale of 0.1. - 0.5 bar, selecting a material that has adequate flexibility and optimizing the dimensions of the seams and gaps. The ventilation cover can have, for example, a diameter of 10-30 cm, for example of approximately 15 cm. The trigger cover it can have, for example, a diameter of approximately 5 cm-12 cm, for example approximately 7 cm. However, other dimensions may also be used for the vent cover and / or the trigger cover, if present, and if desired. The containers of the present invention are particularly suitable for the storage and / or transportation of compositions which are susceptible to exothermic decomposition, in particular peroxide formulations, optionally dissolved in phlegmatizers or in aqueous solutions, emulsions or suspensions. Generally, said containers may have a content of 600-1,400 liters, for example of approximately 1000 liters, although the content may be higher or lower, if desired. The ventilation cover of the invention can be mounted in any type of container known in the art. Containers can also be made with various types of materials, such as metal containers, wooden containers and composite or plastic containers. In one embodiment of this invention, the vent cover is fitted in a container that is equipped with a special gagging strip that is spring-loaded to seal by means of a lid, said gagging strip will release the lid at a certain level of pressure super atmospheric in the container. Such containers are generally used for the transport and storage of compounds or compositions that are susceptible to exothermic decomposition. This invention has the advantage of making possible the transport and / or hermetic storage to the leaks of peroxides, and to prevent the cracking or fragmentation of the container. Examples of this embodiment are described in WO 95/26911. In another embodiment, the vent cover is fitted in a container that has at least one rupture area that is located above the liquid level in the container, when the container is filled with said liquid. The rupture area is defined as a weaker part of the container in which, when the excessive pressure inside the container increases, the rupture area will be broken first before the walls, including the top and bottom, do so. The rupture area can be made with a weaker material than the material surrounding the rupture area, or it can be made with the same material but weakened in relation to the surrounding material. In a modality, the breaking area becomes thinner than its surroundings. The rupture area can have any shape and size, as long as it is above the level of the liquid that is contained or that will be contained in the container, in one mode, the rupture area coincides with the upper side, which is made by at least partially thinner than the bottom and side walls. In one embodiment, the container comprises a ventilation cover on the upper part of the plastic inner container, said container is placed on a pallet and is surrounded by a metal frame. The construction of the inner plastic container is such that at least one part of the upper side of the container is thinner than the bottom and that the side walls. The bottom and side walls of the inner plastic container are secured by a metal frame and bottom construction the size of a pallet, while the upper side is less secured by a metal frame. At a certain level of super atmospheric pressure in the container, the ventilation cover will open first. If the pressure rises further the weaker construction of the container will break in a controlled manner. In this way a sufficient ventilation opening is created to release all gaseous decomposition products and no fragmentation or explosive rupture of the composite container will occur, allowing the liquid composition to remain in the container. In this embodiment, these composite containers would be suitable, initially, for the transport of various kinds of liquid organic peroxide formulations and, although not preferable, other substances as mentioned in this patent application. It is also contemplated to use containers with at least one rupture area as described above, without relating to the ventilation cover. In one embodiment, the invention relates to a container containing a liquid composition that is susceptible to exothermic decomposition, comprising a rupture area above the level of the liquid composition. The container can be made with any material known in the art for such containers. Preferably, the container is made of a polymeric material such as polyethylene, for example high density polyethylene (HDPE), polypropylene, and polyvinyl chloride. The polymeric material may also comprise additives that conduct electricity and that are capable of reducing any electrostatic energy in or near the container. In a preferred embodiment, the rupture area is made with the same material that is used for the container. These rupture areas are preferably thinner than the material of the walls of the container. These containers may comprise any ventilation cover known in the art, including the ventilation cover described above. The invention also allows the ventilation cover to be absent. The rupture area provides a container that is safe and that can be made of materials such as plastics, which would not normally be used for the storage and / or transportation of liquid compositions that are susceptible to exothermic decomposition, such as liquid peroxide formulations. The invention is further illustrated by the drawings. In the drawings: Figure 1 shows, partially in cross section, a ventilation cover of a container according to the present invention; Figures 2A-2B show a side view of the container of Figure 1.
Figure 1 shows a part of a container 1 with a discharge mouth opening 2 having a peripheral neck 3 provided with an external thread 4. A ventilation cover 5 comprises a body plate 6 for covering the mouth opening of the discharge 2. The body plate 6 of the ventilation cover 5 has a ventilation opening 7 which is covered by a trigger cover 8. Along the periphery of the body plate 6, the ventilation cover 5 has a flange 9 with an internal thread 10 for cooperating with the external thread 4 of the neck of the discharge nozzle opening 3. A gas permeable sheet filter 11 which is made of a perforated plastic sheet material extends over the aperture discharge nozzle 2 and is fixed between the screw connection 3, 4 between the discharge opening opening neck 3 and the flange of the ventilation cover 9. The release cover 8 comprises a cover body 12 with a flange of top pe 13 that covers a neck 14 that surrounds the ventilation opening 7. The neck 14 is provided on its outside with an edge or seam 15. The inner side of the lid flange 13 is provided with an edge or stitch 16 that it is hooked past the edge of the neck 15 to form a union by releasable pressure. The dimensions of the edges 15, 16 and the elastic properties of the selected material are chosen in such a way that the lid 8 jumps to a certain predetermined pressure. Figure 2A is a side view of the container 1 that can be placed on a pallet 17 comprising a support cage 18 with a steel grid construction, as shown in Figure 2B. He Container 1 has a discharge opening 19 on its underside. The ventilation cover shown in Figure 1 is on top of the container 1. The container 1 can have a content of approximately 1, 000 liters.
