Definitions

  • the present invention concerns a moulding and packaging process of cosmetic products in paste, semi-solid or gel form.
  • the invention relates to a moulding and packaging process that allows the cosmetic product to be obtained with a desired shape and, at the same time, also coupled to a support element (also called pan), the latter being adapted to be fixed directly in a primary container.
  • a support element also called pan
  • the invention also concerns the cosmetic product fixed to the support element, and the support element per se used in this process and a kit comprising a mould and said support element used in this process.
  • Cosmetic products of this type belong to the following categories: foundations, eye shadows, blushers, bronzers, highlighters, lipsticks or the like.
  • the cosmetic products concerned by this application have the additional feature of being in solid, semi-solid, paste or gel form.
  • said products are typically in pod form and hereinafter in this description will be identified, as a whole, as cast products or, more specifically, poured products.
  • these cosmetic products are obtained by means of a moulding process by pouring into a support, the latter being in the form of a receptacle with a wide opening.
  • the process makes use of mechanical, or volumetric, dosing devices, which dose the semi-finished cosmetic product poured inside the receptacle from said opening in a suitable quantity in relation to the filling volume desired for the receptacle into which the cosmetic product flows.
  • the cosmetic product is, at this stage, mainly semi-fluid and therefore is evenly distributed inside the receptacle, in which it will be cooled to solid state.
  • the cosmetic product will thus have a flat surface at the opening of the receptacle.
  • the solid cosmetic product contained in said receptacle will be subjected to packaging. After the packaging is opened, the cosmetic product will present this flat surface to the consumer.
  • the drawback of this process is that it is not possible to give said surface of the cosmetic product displayed to the consumer a three-dimensional shape that represents, for example, a brand, a pattern or the like.
  • the moulding process involves the use of a mould comprising at least one hollow body having a hollow body delimited by a wall with a moulding surface and an access opening delimitated by an edge. The latter is placed on the back of the mould.
  • the mould further comprises a multifunctional element delimited by an edge.
  • This multifunctional element is a closing element as it acts as closure of the opening of the hollow body; this closing element is positioned at the same level as the edge of the opening. In other words there is no overlapping between the closing element and the edge of the opening.
  • This multifunctional element also acts as support element of the cosmetic product once packaged.
  • the body is made of a flexible polymeric material.
  • the closing element is made of plastic material, such as acrylonitrile-butadiene-styrene (ABS) copolymer or polymers with equivalent mechanical properties.
  • ABS acrylonitrile-butadiene-styrene
  • the hollow body is adapted to receive the cosmetic product in liquid, or at least semiliquid, state.
  • the hollow body is closed by placing the closing element on its access opening.
  • the closing element is provided with holes arranged in the central area.
  • the cosmetic product is poured into these holes, which allow the cosmetic product to pass into the hollow body of the mould.
  • the cosmetic product is then solidified inside the mould into which it was poured.
  • the closing element will form a single body with the cast cosmetic product.
  • the use of the mould makes it possible to give the cosmetic product a predetermined desired shape and, for example, to reproduce a brand or a figure on the surface of the cosmetic product that faces the consumer.
  • the plastic material of which the closing element is made primarily allows a reduction of the weight of the finished packaging and of the costs of packaging materials.
  • a significant drawback of this process is that the mould is filled using a method that does not allow rapid filling thereof.
  • a further drawback is that of having to use a mechanical or manual method for movement of the multifunctional element, whether considered individually or after being coupled to the cosmetic product.
  • the Applicant has now surprisingly found an alternative process for moulding a cast or poured cosmetic product P, generally a pod, that overcomes the drawbacks of the aforesaid processes.
  • a first object of the present invention is to provide a process that can use a wider range of formulations of cosmetic product.
  • the process according to the present invention allows the use of formulations with a wider hot viscosity range with respect to a process of the prior art in which the cosmetic product must flow through the holes of a support element.
  • a second object of the present invention is to provide a process that uses a mould that can be filled with a cosmetic product at a greater speed than the process described in the patent application EP 3669700 Al.
  • An evident advantage is that the whole process for moulding and packaging a cosmetic product is faster.
  • a further object of the present invention is to develop a process that involves the use of a support element and a mould having a hollow body with an opening, and positioning the support element, whose shape and extension not limited by the shape and the extension of said opening, inside the mould.
  • the practical advantage of this is that as the support element has an extension smaller, typically much smaller, than the width of the opening of the hollow body of the mould and a shape that is fully comprised within the opening, it allows the same type of support element to be used for moulds with openings of different width and shape.
  • Another object of the present invention is that of improving release of the cosmetic product, once solidified, from the mould.
  • the support element does not rest on the edge of the chamber of the mould it does not create a limitation of physical interference that causes an obstacle during extraction of the solidified cosmetic product from the mould.
  • the object of the present invention is a process that overcomes said drawbacks through the use of a mould with support element according to the present invention, this process, mould and support element being in accordance with the appended claims.
  • the process according to the present invention relates to the moulding of a poured cosmetic product P, according to which moulding is obtained by means of a mould provided with an access opening and a support element as described below, this process comprising the following steps:
  • solidified product or product in solid state or similar means a product that is no longer in a pourable state, but has taken the consistency of the final cosmetic product, typically in paste, semi- solid or gel form.
  • melted cosmetic product means a completely melted or even only partially melted or softened product, unless otherwise specified.
  • Said mould comprises at least one hollow body having a chamber that is (a) delimited by a wall with a moulding surface and (b) provided with an access opening defined by a perimeter.
  • a margin extends from the hollow body in a radial direction from said opening.
  • Said chamber is made of a material adapted to withstand high temperatures, for example from 60 to 120°C, such as those of the hot cosmetic product when it is poured into the chamber of the mould.
  • This material is, for example, a thermoplastic polymer such as PETG, PVC, APET.
  • Said chamber is of any shape, typically semi-spherical.
  • the chamber has a portion depicting a three-dimensional representation, such as a figure, a logo, a brand, etc.
  • This representation is on the wall or on a wall or, typically, on the bottom of the chamber.

  • retaining face the face opposite the retaining face
  • bearing face the face opposite the retaining face
  • This horizontal surface has any shape, i.e., it can differ from the shape of the access opening.
  • This horizontal surface can have a circular shape, the shape of another geometric figure or an invented shape.
  • This horizontal surface of the support element has a surface that is significantly smaller, i.e., not exceeding 80%, with respect to that of said access opening, as specified below.
  • the horizontal surface of the support element has a surface typically ranging from 20 mm 2 to 13000 mm 2 .

  • this face comprises a central area and a peripheral area, the latter is a circular crown with respect to the central area, i.e., the peripheral area is arranged around the whole of the edge of this element. Both said areas are flat.
  • the central area is raised with respect to the surrounding peripheral area.
  • This area is generally in a oblique or even vertical plane.
  • Said through holes are located in this peripheral area and typically on a same concentric line. This line is preferably in the portion of the peripheral area contiguous to the intermediate area.
  • the first area is in the central part of the bearing face of the support element.
  • This central area of the retaining face of the plane forms the retaining foot.
  • the at least one retaining foot thus has a regular shape, such as a parallelepiped, a cylinder or a truncated cone, the last typically with a circular section. Therefore, this foot has, at a first end, a flat base that acts as bearing surface of the foot.
