Description of the invention

An object of the present invention is provide a recerrable closure that is not plastic for a container and that is easy to put on and put back without needing no tool

According to a first aspect, the present invention is refers to a recerrable closure according to claim 1.

The container and lid can be cylindrical, oval or elliptical, or they can be a polygonal container, such as quadrangular or rectangular.

The skirt can be extended along a outer surface of the curled part and hook an edge of the curled part and / or projections, which may be outer extension beads / corrugations on the side wall of the container.

The closure may comprise a skirt non-metallic In some embodiments the closure can comprise a plurality of skirts non-metallic such as two or three or four or five or six or seven or eight or nine or ten. Skirts non-metallic can be fixed to each other or be you can separate from each other, for example, by a line of break in the skirt.

Preferably, the skirt comprises a first part fixed to the lid and a second part that can be folded between a blocking position where said blocking means engages said curly part and / or projections and a position of unlocking where said locking means is disengaged from said curled part and / or projections. Preferably, the skirt it comprises a folding line around which the second part can shift out and up when going from the lock position to unlock position. In position unlock, the second part can stand out from the first part.

This curled part can define contact surfaces for said cover means and of blocking.

In a preferred embodiment, the blocking means comprises a peripheral extension rib that can be hooking a part of said curly part and / or said projections The rib may be formed with a curved part which has a radius, which corresponds to the radius of a curved part of said curled part and / or said projections.

The skirt can comprise a rib resilient, for example made of rubber, that hooks the part of the curled part and / or the projections.

Preferably, the skirt extends continuously along the entire circumference of the container (if the container is cylindrical, oval, elliptical or polygonal) but as an alternative, the skirt can consist of two or three or four or more individual skirts, so that the lid is locked on the container by individual skirts not connected.

At least a part of the blocking means can be pull apart. For example, a part of the hitching rib can be separable The separable part of the locking / ribbing means of hitch can be adapted to provide an improved hitch with the curled part or projection (s) of the container compared to the non-separable part of the locking means / coupling rib. Thus, after the removal of the separable part of the blocking / ribbing means of hitching, it may be easier to remove the closure. After the removal of the separable part may still be necessary to twist or pull the non-separable part of the middle of hitch lock / rib during closure removal.

In one embodiment the blocking / ribbing means of engagement can comprise a first part and a second part, in which the engagement surface of a cross section of the first part is larger than the hook surface of a cross section of the second part. In one embodiment the thickness of a cross section of the first part can be more Thick than a cross section of the second part. Due to the thicker part, the hitch surface may be larger or may be harder to twist the hitch rib beyond the curled part or projection (s). Bliss First part can be separable.

In one embodiment, the closure may comprise gripping means adapted to facilitate the removal of the closing. The gripping means can serve as a handle and the handle position can result in a hitch improved and reduced between the closure and the container. The means of grip can also be adapted to facilitate fixing the Close the container. The closure may comprise one or two or more gripping means The gripping means may be adapted to be used as handles during transport of container.

In order to facilitate the folding of the skirt between its locking and unlocking positions, said skirt can comprise one or more tear holes that extend transversely to the circumferential direction of the skirt. Of this mode, the forces required to fold the second part of the skirt former minor, when the perforations are detached.

The skirt can also comprise one or more slits (not perforated) that extend transversely to the circumferential direction of the skirt.

Preferably, the grooves and / or perforations they extend in the second part of the skirt only, but can extend both in the first and the second part of the skirt.

The skirt is welded to the lid, so that the skirt is welded between two flanges arranged in opposition.

The lid can comprise a wall part attachable to an internal surface of the container defined by its side wall, said wall part defining and said skirt a cavity for said curled part of the container. The part of wall can be tilted outward, so that in this way the wall part and the inner surface of the container can engage with friction with each other so that the lid is hold in position in the opening of the container even if the Skirt is not in its locked position.

In another embodiment, the lid comprises a substantially flat cover surface perpendicular to the side wall of the container and without extending inside the container, so that you can do without the wall part mentioned above. In this case the lid is can block against the container using only the skirt

The inner surface of the container can understand corrugations, which prevents a capillary increase in contained in the container so as to prevent the contents leave the container.

In order to provide a waterproof closure for the container, a compound (a material for provide a waterproof / waterproof closure) between the lid and the container. The compound may, for example, be a rubber band. or a silicone band sprayed on or an elastomer or a Soft polymer or a synthetic rubber compound.

The compound can be placed between the wall side of the container said wall part of the lid, as in the inside of a corrugation in the side wall of the container the wall part.

Alternatively or additionally, the compound is you can place between the skirt and the side wall of the container, such as inside a corrugation on the side wall of the container on the second part of the skirt. The compound can, for example, constituting the aforementioned rib, or the compound can fit just to said cap or said skirt.

Preferably, the lid is made of metal, but it can be made of cardboard or composite materials or glass or wood. The skirt is preferably made of a plastic resilient / flexible, such as PELD or PP or PEHD or PET or PMMA or PA or elastomer or rubber.

It can be an advantage of lid closures metallic that are not flexible compared to the covers of plastic. The solidified material in this way on a surface internal may not be performed on scales when the closure is separated or has been fixed again, since the metal covers do not they can be twisted or folded to the same extent as the covers of plastic. At the same time a skirt made of a plastic material can provide the folding properties of the present request. Since the skirt is foldable, it may be possible provide an improved engagement between a rib portion of the skirt and an edge of the can. This is due to the fact that the closure does not need to be adapted to be removed from the can when the ribbed part of the skirt and the edge of the can are hooked

The container can contain products food, solvents, chemicals, paints since the lid provides a tight and lockable closure, but the container and lid can of course also be used for other Goods, such as cookies. The container can be made of metal, plastic, composite materials, cardboard, glass or wood.

When the container closure is removed, the second part of the skirt can be folded / twisted in the position of unlocking and then closing can be lifted from container. When the closure is mounted / reassembled, the second part of the skirt can first be twisted / folded in alignment with the first part of the skirt and then the closure slides down until the locking means they hook the curled part and / or the projection. The procedure to mount / reassemble the closure in the container can understand the conventional procedure of pressing down the closing, for example, by the person filling out the container.

The closure can be applied for a batch of known containers that have a curled portion, and as the closure can be mounted on such containers by using conventional production equipment, the closure can be sold separate (not together with a container) to the manufacturers of containers As the closure can be sold separately, the volume Packaging for export is minimized because the closure It can be stacked very close.

Instead of aligning the second part with the first part before mounting the closure on the container, the closure It can be placed over the opening of the container and then the second part of the skirt can be twisted / folded into position lock

According to a second aspect, the present invention refers to a method according to claim 24.

The stage of providing the skirt can understand extrusion or injection molding of the skirt.
