FR2622872A1 - PERFECTED METAL CONTAINER WITH HERMETIC COVER - Google Patents

Abstract

The container 1 comprises on the outer edge of its opening, a curved upper part 6 which extends into an outer part 7 of downwardly divergent shape, to form in the lower part a large curved section 8. On the underside of this edge. , the side surface of the container 1 forms an annular projection 9 forming a very open internal "U" channel. The cover 2 has a considerable depth and comprises a bottom disc from which emerges perpendicularly an annular wing of great height. This cover has, as a feature, that its outer side wall comprises a plurality of protrusions 12 equidistant from each other, which are elongated in the direction of the circumference and at a wide angle. These protrusions 12 are complementary to an internal and annular channel of the container 1 so that, during the assembly of the cover 2 and the container 1, there is a stapling between them. The cover also has a gasket 5.

Description

The invention relates to an improved metal container provided with

  a hermetically sealed lid.

  The type of containers into which improvements have been introduced, which is the subject of the present invention, is obtained from a roll wound on itself to take the form of an empty cylindrical body and / or a conical trunk. o one of its bases is materialized by a fixed disk with crampon or staple on the corresponding edge of this same base, while the opposite base constitutes the opening and is completed,

  obviously, by the corresponding lid.

  The edge of this opening, in the type of container referred to, has a special shape obtained by stamping or appropriate process and known per se, forming a top and outer rim on which rests an edge all around the perimeter of the lid, with the interposition of a rubber gasket or the like, so that the edge of the container opening as the edge of the lid have a shape such that with other means provided on the surface lateral contact between the lid and the container, it occurs a stapling between the two parts and that we obtain the desired closure, or what is the same

  thing, blocking the lid on the container, both the.

  seal interposed between the edges of this lid and the container

  constitutes the hermetic means of this closure.

  There is no doubt that there is, at the present time, a significant manufacture of metal containers based on the principles of construction mentioned above and which give rise to innumerable changes of shape as to the edges and the means of construction. stapling to try to obtain a container having a suitable closure, non-deformable, which does not open during an accidental fall and yet allows easy opening by means of a tool

appropriate.

  In spite of the innumerable types of existing containers, none of them has however managed to reunite all the advantages which they present separately: and this is due to the fact that the known containers having a good resistance of closing and opening are difficult to open and close, and those with easy closing and opening conditions have the disadvantage of not being adapted or producing a bad stapling between the

2 2622872

  lid and the container. It would be possible to list types of receptacles which, while effectively fulfilling one of these purposes or conditions, leave much to be desired as to

  one or other of the conditions and purposes, without exception of any type.

  The subject of the present invention relates to a series of improvements relating to the type of containers described above, which result in such a structure of the opening and the lid, which effectively fulfills all the conditions or requirements, which still has advantages in offering a simpler container than any of those already known and which is of course

more efficient and more advantageous.

  More concretely, the essential feature of the container is that the outer edge of its opening has a curved upper portion with upward convexity. The curved part continuing with an external part of profile diverging downwards, to form, in its lower part, a large curved section

  greater than half a ellipse, of convexity turned downwards.

  Below this edge, the lateral surface of the container has a projecting ring of very large angular profile, determining a

  internal "U" channel and very open.

  On its side, the lid is of the type of those having a large depth, comprising a bottom disc of o emerges perpendicularly an annular wing of a large height which, assembled on the container, remains in contact with the inner surface

from the wall of it.

  This cover, in accordance with the subject of the invention, has the particularity that its external lateral wall has a plurality of equidistant portions which are elongated in the circumferential direction and at a large angle, the protruding parts. being complementary to the internal and annular channel of the container so that when assembling the lid thereon, stapling occurs and therefore the locking between them of the two

parts (lid and container).

  Another peculiarity of the lid is that its edge has an outer section of practically semi-circular profile with a concavity downwards, ending finally with an outer loop as rigidity rib, which remains on a vertical plane set back from the more protruding from the edge or the convex portion

bottom of the container.

  Between the curved upper part of the edge corresponding to the opening of the container and the concave part corresponding to the edge of the

  cover, is interposed and tightened the corresponding seal.

  As a result, from the structure described, the closure or stapling between the lid and the container is easily achieved, giving rise to a perfect lock resulting from the projecting parts of the container.

  cover that lodge in the annular recess of the container.

  Similarly, the opening is easily made without any deformation of the lid, since the loop external to it gives it a rigidity that perfectly supports the lifting performed

when opening.

  The stapling between the lid and the container, as a result of the special shape of the protruding parts of the lid and the recess of the container prevents opening and deformation of the closure in case of accidental dropping or impact of the container against a hard surface.

  The invention will be better understood on reading the description

  Detailed description which will follow, made with reference to the accompanying drawings, forming part thereof and given here only by way of example and among which: FIG. 1 shows a partial side view of the container and lid assembled together, it corresponds to a section through a vertical plane passing through the projecting stapling portions of the container and

of the lid.

  Fig. 2 shows a view similar to FIG. 1 but in this case with the vertical cutting plane passing through another area included

  between two protruding parts of the lid.

  Figs. 3 and 4 show two horizontal sections represented

  by the lines III-III and IV-IV, respectively in Figs. 1 and 2.

  Fig. Fig. 5 shows a plan view of the lower part of the lid, and 6 shows a side elevational view of the lid,

with partial snatch.

  As can be seen in the figures mentioned above, the container (1) and the corresponding lid (2), both of conventional shape, have a series of structural features

  new, as regards the means of assembly between them.

  In this sense, it can be seen that the lid (2) has a convex and curved edge (3) terminated in an outer loop (4) so that the concavity of this flange (3) can receive a seal (5). ) which during the assembly of this lid on the container (1) presses and presses on the convex flange (6) thereof, which rim extends on an outer and divergent length (7) downwards, which is curved and comprises a convex lower portion (8) with

a protruding part (9).

  Near the rim of the container (1), the latter has a circular or annular deformation (10) which defines an external angular projection, above which there is a small internal annular projection (11), so that in the angular recess that determines the projecting portion (10) are located and fit a plurality of angular and complementary projections (12) provided for this purpose, at equal distances, in

  the side surface of the lid (2).

  The advantages derived from the described structure can be summarized as follows: 1. As a consequence of the convexity (3) of the rim of the lid (2), lifting it to open, said lid undergoes no deformation, which allows to use said lid as many times as desired, always obtaining a tight seal, which is not obtained in conventional containers o the convex and curved section (3) of which we speak, is usually straight and horizontal, resulting in deformation in the aperture and therefore renders

  unusable this lid at the first opening of the container.

  2. Having the convex and curved shape (3) mentioned above, said cover (2) acquires greater rigidity, which further facilitates the opening and helps prevent its deformation

during such an opening.

  3. Having an outer loop (4), this cover is more difficult to build, since it facilitates the exit of air in the process of applying the seal (5) on the concavity of the flange of the

cover (2) mentioned.

  4. The most protruding part (9) of the rim of the receptacle protrudes much in the vertical plane the own loop (4) or the most extreme part of the lid (2). This implies that in case of drop of the container, the shock in this zone will necessarily occur on

2622872

  the most protruding part (9) that has already been mentioned, this part acting as damper and protector of the cover (2), this

  which obviously will prevent accidental opening.

  5. As a consequence of the protruding parts (12) of the cover (2), those being spaced apart, it will be when assembling on the container (1), as many other chambers (13) which, in case of impact on the lateral surface of the container will act as a damper so that the container bends and the accidental opening of the lid (2) does not occur as happens with the conventional lids o the projections (12) are reduced to a single continuous projecting portion all along the contour, not forming damping chambers. It should also be noted that as a consequence of the separation between these projecting parts (12), the opening will be made easier and therefore the closure, unlike the rigidity that conventional lids have with the embedding of the protrusion

  continuous on the angular reentrant of the container (1).

Claims (1)

CLAIM   An improved metal container (1) provided with a lid (2) corresponding to a hermetic closure, said container having a flange (6) corresponding to its opening, on which a gasket (5) in another flange (3) provided in the lid (2) corresponding, and provided, in addition to the container (1) and the lid (2), complementary means (12) of embedding and locking to achieve the corresponding closure between these elements, characterized by the fact that the flange (3) of the lid (2) o is housed the gasket (5) is curved and convex upwards, preventing its deformation when lifted when it is opened, this curved and convex shape offering, in addition, a greater rigidity of the cover (2), which also comprises an outer loop (4) facilitating the exit of the air in the method of applying the seal (5), the complementary means (12) of embedding and locking in the closed eture being constituted by angular projections spaced apart from each other, provided on the lateral surface of the cover (2), these projecting parts fitting into an angular channel determined by an annular deformation (10) provided in the container (1) of in such a way as to form respective chambers (13) between the projections (12) of the lid (2) which allow the container (1) to cushion shocks on its lateral surface, thereby preventing any accidental opening of the lid and, being on the other hand an easy opening for the user, because there is no continuous rigidity in the recess between the lid (2) and the container (1), with, in addition, the particularity that the flange (6) upper part of the container (1) extends downwards in divergent form and ends in its lower part by a curved shape and   convex (8), with a projection (9) which exceeds considerably   vertically, the loop (4) or the outermost part of the lid, so that during any fall, the impact is distributed on this projecting portion (9) of the flange (6) of the container ( 1) which acts as damping and protection means for the cover (2), preventing impact on the cover (2) and, therefore ,. his accidental opening.
