Definitions

  • the present invention lies in the sector of the manufacture of containers.
  • the present invention lies in the sector of the containers used for containing fluid products, like bath or cosmetic products, such as shampoos, body washes, toothpastes, cosmetic creams and the like, or food products, such as food sauces like ketch-up, mayonnaise, etc.
  • fluid products like bath or cosmetic products, such as shampoos, body washes, toothpastes, cosmetic creams and the like
  • food products such as food sauces like ketch-up, mayonnaise, etc.
  • the present invention relates to a container in the shape of a tube, preferably a collapsible tube suited to be squeezed to allow the product contained therein to flow out.
  • These containers typically consist of a tubular- shaped main body for containing the product and a closing portion, suited to close the main body, on which an opening for dispensing the product is defined.
  • a closing cap is then associated with the opening, normally a cap applied by pressure or by screwing.
  • the main body and the closing portion are made separately to be then suitably joined.
  • the main tubular containment body is preferably made with a plastic material with elastic yielding properties, preferably by means of injection moulding, drawing, rolling or extrusion techniques.
  • the closing portion is also preferably made with a plastic material, typically having greater mechanical hardness characteristics than the main body so as to ensure, for example, a greater mechanical seal in the area of application of the cap.
  • the closing portion where the opening for dispensing the product is present is in the shape of a truncated cone defined by a sloping surface that from the external peripheral surface of the main body narrows down towards the centre where the dispensing opening is present.
  • the sloping surface favours the flowing of the product flow from the inside of the container towards the dispensing opening, for example when the container is squeezed.
  • the angle of inclination of the sloping surface is kept relatively low, for example around 100° with respect to the external peripheral surface of the main body, to contain sizes and use of plastic material.
  • the main body and the closing portion are made separately to be then suitably joined, in particular joined by means of a heat-sealing or laser sealing process.
  • connection of the main body to the closing portion takes place at the level of an upper edge of the main body which envelopes a first part of the closing portion and which is folded over a second part of the closing portion.
  • the upper edge is then joined to the closing portion, preferably by means of heat-sealing or gluing or other connection methods, suited to close the edge on the closing portion.
  • a drawback that this known technique has consists in that, due to the said geometries provided for the closing portion, the joining between the main body and the closing portion is problematic since the folded edge portion of the main body is subject to small folds that hinder the subsequent joining process, for example heat- sealing or gluing.
  • the main object of the present invention is therefore to solve, or at least partially obviate, the aforementioned drawback that characterizes the state of the art.
  • an object of the present invention is that of proposing a container that allows to improve the manufacturing process thereof and improve the quality of the final product.
  • the present invention therefore relates to a container for a fluid product comprising a dispensing opening suited to dispense said product and associated with a terminal area of said container, said container comprising:
  • main body that extends along a main axis in a tubular shape and is suited to define an internal area for housing said product, said main body comprising a closed bottom area and an edge facing towards said terminal area;
  • said closing portion comprising a joining area suitable for connecting said closing portion to said edge of said main body and a transition area between said joining area and said opening, said edge of said main body comprising a first annular portion suited to be externally connected to a first surface of said joining area and a second portion, folded with respect to said first portion, which extends from said first portion in the direction of said main axis and is suited to be connected to a second surface of said joining area; wherein said first surface and said second surface of said joining area of said closing portion define respective directions which together form an angle included between 115° and 140°, preferably included between 117° and 130°, more preferably equal to 120°.
  • the first annular portion of the edge comprises a cylindrical portion and/or the first surface of the joining area comprises a cylindrical surface and/or the second portion of the edge comprises a truncated cone-shaped portion and/or the second surface of the joining area comprises a truncated cone-shaped surface.
  • the transition area defines a respective sloping transition surface, wherein the sloping transition surface identifies a respective direction that defines an angle included between 90° and 110°, preferably included between 95° and 105°, more preferably equal to 100° with respect to the direction of the first surface of the joining area.
  • the transition area is in the shape of a truncated cone.
  • the main body and the closing portion are made of plastic material.
  • connection of the closing portion to the edge of the main body is a connection obtained by means of a sealing process, preferably a heat-sealing or laser sealing process.

  • the main body 2 preferably has a cylindrical tubular shape. In embodiment variants, different shapes may be provided, for example a shape that is elliptical tubular instead of cylindrical.
  • the bottom area 4 of the main body 2 preferably has a crushed and closed shape along an edge portion 4a.
  • this edge 4a is advantageously obtained by means of closing by heat-sealing after the product has been inserted into the internal area 3 of the main body 2.
  • the main body 2 develops towards the upper end 5 ending with said edge 6, preferably cylindrical in shape.
  • a closing portion 20 which is suited to close the main body 2, or shoulder, on said closing portion 20 there being defined, in turn, the dispensing opening 7.

  • This also results in a reduction in the overall dimensions of the cap 50 which may also have a lower height, the cap 50 preferably being shaped to have a collar 51 suited to cover the transition area 24 of the closing portion 20.
  • the value of the height H of the transition area 24 will depend on the sizes of the container 1, in particular on the sizes of the main body 2 and of the connection means 52 for the cap 50.
