Abstract: Airless tubular container (1) with an outer tube (1a) and an inner container (1b) both provided with respective skirts (2a, 2b). The inner container (1b) comprises an adapter (3b) to couple the inner container (1b) to the outer tube (1a). The skirt (2b) of the inner container (1b) is joined to the adapter (3b) and comprises a deployable portion (20) arranged under the adapter (3b). The deployable portion (20) enables the length of the skirt (2b) of the inner container (1b) to be adjusted with respect to the length of the skirt (2a) of the outer tube (1a), during the manufacture of the tubular container (1). Furthermore, the deployable portion (20) allows a relaxed collapsing of the inner container (1b) during use of the tubular container (1).

Abstract: Tubular container (1) made of a flexible material, which comprises an outer tube (10) and an inner container (30) housed inside the outer tube (10) and intended to come into contact with the packaged product (51). A flexible shoulder (32) of the inner container (30) is secured to a head (12) of the outer tube (10), there remaining an intermediate cavity (7) between the outer tube (10) and the inner container (30). At least one orifice (24) communicates the intermediate cavity (7) with the exterior of the tubular container (1). The head (12) may include a one-way airless valve. The outer tube (10) may recover its shape whilst the inner container (30) remains compressed during the use of the tubular container (1). The outer tube (10) and the inner container (30) are preferably made out of materials that fulfil different requirements. The distal end (36) of the inner container (30) is preferably flared against the outer tube (10).

Abstract: Tube made of flexible manufactured material and a procedure for its manufacture, where all or part of the tube is manufactured by the injection molding of a formulation of plastic materials, which comprises at least one base Random-type polypropylene with an E modulus of between 300 and 1400 MPa, at least another Random-type polypropylene, with a melt flow of between 8 and 75 MFI 230/2.16, at least one copolymer with a modulus of between 10 and 500 MPa, at least one nucleating agent and/or at least one thermal stabilizer. The resulting tube fulfills diverse requirements for flexibility, permeability, welding capacity, mechanical resistance to low temperatures, etc.

Abstract: A closure device to be connected to a container, which includes a cap, a moving shutter and a lid, where the moving shutter is housed in a compartment of the cap and presents a platform provided with holes, two elastically deformable tongues and a body with a cylindrical section held in place and guided by a chimney in the lid, where the lid includes a central hole that allows the product to exit. The moving shutter is operated by pressing on the elastic container, which allows a dose of the product to come out, the moving shutter then being returned to its rest position by the tongues.

Abstract: Procedure for the manufacture of a tube made of a flexible material and comprising a skirt and a head, in which a unit formed by the skirt and an appendage is disposed or manufactured in an injection procedure, the appendage totally or partially closing one end of the skirt and including the injection point(s), in which the appendage is cut totally or partially, and the cut part is removed, and in which the head over-molded on any area of the part of the unit formed by the skirt and appendage that remains once the cut part has been removed. The appendage offers several advantages, such as improving the finish of the over-molded head or, in the event of the unit being manufactured, easing the removal of the unit from the mound.

Abstract: Closure device, to be connected to a container (1), which comprises a measuring cap (2), a moving shutter (17) and a lid (24), where the moving shutter (17) is housed in a compartment (3) of the measuring cap (2) and presents a platform (18) provided with holes (19), two elastically deformable tongues (20) and a body with a cylindrical section (21, 22) held in place and guided by a chimney (27) in the lid (24), where the lid (24) comprises a central hole (29) that allows the product to exit. The moving shutter (17) is operated by pressing on the elastic container (1), which allows a dose of the product to come out, the moving shutter then being returned to its rest position by the tongues (20).

Abstract: Procedure for the manufacture of a tube (1) made of a flexible material and comprising a skirt (3) and a head (10), in which a unit (2) formed by the skirt (3) and an appendage (4) is disposed or manufactured in an injection procedure, the appendage (4) totally or partially closing one end of the skirt (3) and comprising the injection point(s), in which the appendage (4) is cut totally or partially, and the cut part is removed, and in which the head (10) over-moulded on any area of the part of the unit (2) formed by the skirt (3) and appendage (4) that remains once the cut part has been removed. The appendage (4) offers several advantages, such as improving the finish of the over-moulded head (10) or, in the event of the unit (2) being manufactured, easing the removal of said unit (2) from the mould.

Abstract: Procedure (25) for the manufacture of a tube (31) made of flexible materials provided with a skirt and head, in which a skirt-semihead unit (26) of the tube (31) is manufactured in a first in-mould injection process (9) that includes in-mould labelling, the head (20) of the tube (31) then being applied on the skirt-semihead unit (26) in a second process (29), preferably an over-moulding process and with the head (20) embedding the semihead (27). By means of this procedure (25) it is possible to avoid the use of printing machines as well as the use of alternative out-of-line decoration machines, thereby cutting manufacturing times and costs.
