Definitions

• the present invention relates to a container or container, generally for packaging use, such as box, bucket, pot, tray, tray, comprising a closure device, the sealing and inviolability of which are obtained by simple mechanical process, without welding. no use of glues.
• This container will most often be made of plastic, but it can be made of any other type of material, such as glass, cardboard, aluminum, zamak, sheet metal or composite material. Only the movable elements of the closure device must be made of plastic, rubber or other semi-rigid material.
• the tightness or inviolability of the closure of a container or of a packaging is obtained, either by crimping the lid if it is a sheet steel packaging or d aluminum, either by heat welding or by gluing a plastic or aluminum film to the upper edge of the packaging, in the case of a container or a packaging made of material plastic, this film can sometimes completely surround the packaging, and form gathers which are welded or glued together on the outer bottom wall of the packaging.
• this method of affixing the protective film closes the holes reserved in the side walls of the packaging, and intended to allow the aeration of the products and their protection against mold in the case of fruits or vegetables in particular. In addition, this method quadruples the amount of plastic film used.
• Existing packaging does not offer the possibility of successive re-uses with the same sealing and inviolability qualities, without the need to use bonding or welding of a new seal, which are only possible if the flatness of the upper edge of the packaging was preserved when the previous cover was removed.
• the existing packaging does not allow to put away from the air the products they contain such as paints, varnishes, mastics, which are not fully used after the first opening, and which tend, once the container open, allow their volatile components to evaporate and therefore dry out.
• the object of the present invention is therefore a package comprising a closure device ensuring it by a purely mechanical process, both sealing and inviolability without the use of bonding or welding, this closure device can be combined with a gripping device facilitating handling and manipulation.
• the object of the present invention is also a packaging comprising a closure device requiring no costly investment for its implementation which may consist either in carrying out a simple manual application of the protective film and the rod intended to block it, or using a press fitted with an unwinder and operated by hand;
• the object of the present invention is also a packaging making it possible to return and keep away from the air all the products, such as paints, varnishes and industrial adhesives in particular, in the manufacture of which volatile components enter, and which of this fact is subject to rapid drying as soon as the cover is removed from the traditional packaging in which they are packaged.
• the aim of the present invention is finally to offer a packaging, the closure device of which is a simple and effective means of protecting the products, either during their initial packaging, or on the occasion of subsequent repackaging.
• the invention mainly relates to a packaging such as, box, bowl, tray, tray, tray, bucket, pot, tube, without this list being limiting, characterized in that it comprises as first closure device, an element fixed formed by a U-shaped groove reserved around the entire periphery of its upper edge. The bottom wall constituting the bottom of this groove will have one or more orifices.
• the invention also relates to a packaging characterized in that it comprises a second movable and removable element, consisting of a single strand of plastic, rubber, or any other semi-rigid material, called a rod, exactly matching the U shape. of the groove reserved around the entire periphery of the upper face of the package, the surface of which it completely covers without overflowing.
• a packaging characterized in that it comprises a second movable and removable element, consisting of a single strand of plastic, rubber, or any other semi-rigid material, called a rod, exactly matching the U shape. of the groove reserved around the entire periphery of the upper face of the package, the surface of which it completely covers without overflowing.
• the invention also relates to a packaging characterized in that the rod has over its entire length a central recess intended to provide it with the elasticity necessary for compensating for the thickness of the film once the latter has been inserted into the throat.
• This central recess will also serve to house the shank of the lugs in the form of harpoons intended to ensure the inviolability of the closure.
• the underside of the rod will be pierced with one or more orifices superimposed exactly on the orifices made in the lower face, or bottom, of the groove.
• the subject of the invention is also a packaging comprising a closure device characterized in that it makes it possible to obtain sealing by the affixing of a protective film of polyethylene or similar material, transparent or opaque according to the desired result, the thickness of which will exceed by a few microns the intervals between each lateral wall of the groove and the rod, once the latter is inserted into the groove, this film being introduced into the groove using the rod by simple manual or mechanical pressure.
• the invention also relates to a packaging comprising a closure device characterized in that it makes it possible not to close off by fallout of the protective film, the ventilation holes that the packaging may have on its side walls.
• the invention also relates to a packaging provided with a closure device characterized in that its upper edge comprises, when it is made of plastic, ribs intended to reinforce its resistance to the vertical pressure exerted during the introduction of the rod in the groove
• the invention also relates to a packaging whose closure device is characterized in that the rod intended to enclose the protective film in the groove, comprises horizontally on one of the internal angles, a tongue intended to facilitate it removal upon opening.
• the subject of the invention is also a package, the closing device of which is characterized in that the recess made over the entire length of the rod also allows the pinning of pins intended to reinforce the solidarity between the rod and the groove, and to prevent any risk of accidental tearing of the rod, therefore of unexpected opening of the packaging.
• the subject of the invention is also a package, the closure device of which is characterized in that the lugs will have a flat face which will rest on the upper part of the rod once the latter is inserted into the groove, and a pole, the length of which will be approximately equal to the depth of the recess in the rod, which pole will be provided at its lower end with barbs in the shape of an arrowhead, the whole being presented as a harpoon. These barbs will present a. slight elasticity, and will have a span slightly greater than the section of the orifices made in the lower walls of the throat and the rod.
• the invention also relates to a packaging comprising a closure device characterized in that it does not prevent, if they are required, the bonding or welding of the protective film overflowing on the outer walls of the groove, or the superimposition of a rigid cover exactly matching the shape of the packaging, to give, if necessary, resistance to crushing
• the invention also relates to a packaging comprising a closure device characterized in that the principle of the rod with obviously central can be integrated in the cover itself.
• the cover will have on its underside a protuberance which will be received in the groove of the packaging.
• This protuberance will have the same characteristics as the single-strand rod, in particular with regard to its size and its elasticity which will be obtained thanks to the central recess; which will guarantee inviolability by the use of locking lugs in the shape of a harpoon under the same conditions as when using the rod.
• the subject of the invention is also a packaging comprising a closure device making it possible to return the contents to the shelter of air after a first opening of the packaging, and again ensuring a new sealed closure, after each of the successive openings
• the packaging comprising the closure device described above will be particularly suitable for packaging consumer products in the food industry, such as fresh products. distributed in trays, seafood, meats, cold meats, ready meals, fresh cheeses in jars, or even ice creams and sorbets. The tightness of the closure will ensure effective protection of the products against pathogenic germs.
