Definitions

• the invention is in the field of packaging comprising a side wall consisting of a laminated film and a bottom welded to said wall.
• the bottom must provide stability, strength and tightness of the package. In particular, it must offer good resistance to deformation when an effort is applied to its center.
• the solution of the aforementioned problem consists of a rigid or semi-rigid plastic part intended to form the bottom of a package whose side wall is made of a laminated film, said part being centered around an axis and including the following features: a. A peripheral welding zone adapted to contact and be welded to the inner surface of said side wall; b. A convex inner surface and a concave outer surface; vs. The inner face and the outer face each having a zone, centered about said axis, which is adapted to contact a tool used for fixing the part to said side wall; d. A profile at least partially defined by a curve which may be an arc of radius greater than or equal to half the half-diameter of the part. Particularly advantageous embodiments of the invention are described in the dependent claims.
• the part according to the invention can have the following characteristics: - minimum weight
• FIG. 1 represents a packaging part comprising a bottom according to the invention
• FIG. 2 illustrates the internal face of a bottom according to the invention.
• FIG. 3 illustrates the external face of the bottom of FIG. 2.
• the bottom 1 illustrated in the figures is circular and has an outside diameter of between 35 and 63.5 mm. Its height is generally less than 35mm.
• the bottom can have a different shape, p. ex. oval or polygonal.
• the bottom 1 preferably has a profile whose curve is a circle of radius r between one and two times the outer radius of the bottom 1. Its height is generally between 10 and 25% of its diameter. This profile is preferably truncated at its center and continued a flat area of diameter equal to 30 to 50% of its outer diameter so as to facilitate its handling from the inside.
• the bosses 9, if necessary, preferably represent 30 to 60% of its projected area.
• the outer gripping zone may be a central disk or a center ring of width approximately 0.5 mm and an inner radius of approximately 85 to 90% of the outer diameter of the bottom.
• the bottom thus defined has a characteristic thickness of the order of 0.8 to 1.5 mm according to its outside diameter and its height.
• the bosses 9 may be thinner, of the order of 20%.
• the angle ⁇ of welding is generally between 45 and 75 °
• This bottom 1 has a general thickness of 1 mm and 0.8 mm in the bosses 9.
• the bottom also has a flat area at its lower end to ensure the stability of the package. In the previous case, this stability is ensured by the crown which serves for the external gripping of the bottom 1.
• the bottom 1 described above is generally manufactured by injection. It can also be produced by compression molding or thermoforming.
• thermoplastic material for example PE, PP or PET. It can also be multilayered so as to contribute to the overall barrier of the package.
• the resulting packaging has excellent stability. It has good static mechanical properties (held under a central load of 4ON, holding pressure) and shock (drop test). It also has the properties required for liquid or air sanitization.
