Definitions

  • the present invention relates to a container for fluid products in general, particularly low-density fluids.
  • fluid products in general such as for example paints, water-based paints and the like, are currently contained in cans provided by means of a body made of tinplate, to which a tinplate end cap is applied which is coupled by seaming to said body.
  • Containers or cans are further known, as disclosed for example in EP 1 102 705 , whose body is made of plastic material and whose end cap is connected by means of a mechanical connection obtained by pinching.
  • This type of solution does not allow optimum stability and further does not prove to be capable of being used for products with low or very low density.
  • the aim of the invention is to solve the problems described above, by providing a container for fluid products in general, particularly low-density fluids, which makes it possible to have a container body made of plastic material to which an end cap made of tinplate is connected thereby allowing to ensure optimum tightness characteristics.
  • an object of the invention is to provide a container that makes it possible to have particularly high tightness values without thereby causing complications during production.
  • Another object of the present invention is to provide a container for fluid products in general which, thanks to its particular characteristics of construction, is capable of ensuring highest reliability and safety of use.
  • Another object of the present invention is to provide a container that can be obtained easily starting from commonly commercially available elements and materials and is also competitive from a merely economical point of view.
  • a container for fluid products in general, particularly low-density fluids comprising a container body that defines a free rim to which an end cap is seamed, which defines an opening that can be closed by a closure element, characterized in that said container body is made of thermoplastic material and defines, at said free rim, a lip that can be jointly connected to the peripheral rim of said end cap made of metallic material by means of a triple seam, said lip being adapted to act as a sealing gasket between said end cap and said container body.
  • the container for fluid products in general particularly low- or very low-density fluids, generally designated by the reference numeral 1
  • the container body 2 to which an end cap 3 is seamed in order to obtain a container which is, for example, constituted by a can; the end cap has an opening which is closed by a closure element, constituted for example by a lid.
  • a peculiarity of the invention consists in that the container body has a cylindrical or frustum-shaped configuration with a bottom and defines a free rim at which a lip 10 is provided which extends radially on a plane which is substantially perpendicular to the axis of the container body.
  • the container body can be made of a thermoplastic material such as grade 5 HD, i.e., high-density polyethylene copolymer, or optionally grade 12 polypropylene copolymer.
  • a thermoplastic material such as grade 5 HD, i.e., high-density polyethylene copolymer, or optionally grade 12 polypropylene copolymer.
  • the end cap 3 made of tinplate can be applied over the lip 10 and has a peripheral rim 20 which terminates with a rim 21 which is folded downwardly.
  • the end cap 3 is arranged, as shown in Figure 3 , over the lip 10 and then the usual seaming operations are performed with successive folds which make it possible to provide with the rim 20 a rising inner portion 30 which is connected to a descending portion 31, which in turn is associated with a rising outer portion 32 connected to the body of the end cap 3.
  • the lip 10 remains seamed between the portions 30, 31 and 32 and has a descending inner portion 11 which is connected to a rising portion 12, which in turn is connected to the lateral portion of the container body 2.
  • the thickness of the lip is greater than the thickness of the end cap, thus achieving a seaming that extends continuously and makes it possible to retain the portions of the lip and of the upper rim of the container between the folded portions of the end cap, so that the lip acts as a gasket element, without the necessity to introduce the traditional sealants which are inserted when a container body made of tinplate is seamed with an end cap made of tinplate.
  • the assembly makes it possible to provide extremely high tightness values, which are optimum even if very low-density liquids are introduced in the container.
  • the end cap designated by the reference numeral 3' has the same elements for connection to the container body 2, and therefore they are designated by the same reference numerals in the drawings; the difference consists in that the upper rim of the container body defines, on its inner surface, a portion 40 that is flared outwardly and in which an inner containment rim 41 is accommodated for mating with a closure element constituted for example by a lid.
  • the inner containment rim 41 is arranged substantially flush with the inner surface of the container body 2, so that it does not constitute any hindrance to the outflow of the product.
  • the rim 41 at the upper end, is connected to an outer fold 42, which is arranged in an upward region, whereas in a downward region it is connected to a lower curve 43, which in turn is connected to a rising rim 44, joined to the rim 20 by means of an inclined rim 45.
  • the flared shape of the rim 40 together with a container body 2 which is frustum-shaped, allows insertion of the empty container bodies and stacking of the same when they are closed by the lid.
  • a container for fluid products in general which has a body made of plastic material to which an end cap made of tinplate is connected which is seamed with a triple seaming process, so that the lip is inserted in the folded portions, providing an optimum sealing element.
  • Another important aspect further consists in the fact that the materials used make it possible to provide a desired degree of elasticity to the material, which can bend easily without being subject to breakage or tears.
  • the materials used, as well as the contingent shapes and dimensions may be any according to requirements.
