Description
- The present invention relates to the field of flexible thin-walled packagings, in jargon called “pouches,” typically provided with a spout provided with a cap. Such packagings are widely used to contain products such as fruit juices, fruit or vegetable puree, yogurt, drinks, creams, honey, mostly intended for consumption by children.
- The sterilization of these packagings has enormous importance for the prevention of infections and the correct preservation of the product contained therein.
- Sometimes, chemical sterilization is carried out, during which the packaging is washed with disinfectant agents, for example hydrogen peroxide, and then dried, before being sent to subsequent filling operations. However, chemical sterilization has some drawbacks such as, for example, the presence of residues of the disinfectant agent in the dry container or the presence of non-disinfected areas due to complex or irregular geometries of the packaging. This drawback is particularly felt in the pouch sector.
- A significant diffusion in the sector, on the other hand, is sterilization by ionizing radiation, such as gamma rays or electron beams. For example, the Applicant is the owner of the International Applications WO-A1-2012/147007 and WO-A1-2012/147008.
- Usually, the sterilization by ionizing radiation is carried out in specialized centers, to which the packaging manufacturer sends the packagings to be treated; after sterilization, the sterile packages are sent to the person who carries out the filling and the application of the closure, using measures that allow the maintenance of the sterility condition inside the packaging. Such logistics obviously imply considerable transport costs between the sites and a considerable complexity of managing the packagings within the sites themselves.
- To overcome this drawback, the Applicant has already devised a system for managing the sterilization of flexible thin-walled packagings in which the use of a plurality of sacrificial closures applied to the spout outlet mouth before sterilization is provided, subsequently separated from the spout in a sterile chamber, just before filling the packaging. This system is illustrated in International Applications WO-A1-2017/001947 and WO-A1-2017/168322.
- As may be understood, in order for this system to be fully effective, the application of the sacrificial closure to the spout outlet mouth should ensure air tightness, in order to prevent the interior of the packaging from being contaminated before filling it in the sterile chamber.
- The object of the present invention is to provide a spout for a flexible thin-walled packaging which is particularly effective for the application of a sacrificial closure.
- Such an object is achieved by a spout according to
claim 1. The dependent claims describe further advantageous embodiments of the invention. - The features and the advantages of present invention will appear more clearly from the following description, made by way of an indicative and non-limiting example with reference to the accompanying figures, in which:
-
FIG. 1 shows an assembly comprising a flexible packaging and a sacrificial closure, according to an embodiment of the present invention; -
FIG. 2a shows a spout according to an embodiment of the present invention, with sacrificial closure applied; -
FIG. 2b shows the spout ofFIG. 2a , with separate sacrificial closure; -
FIG. 3 shows a cross-sectional view of the spout ofFIG. 2 a; -
FIG. 4 shows a sacrificial closure, according to an embodiment of the present invention; -
FIG. 5a shows the spout according to the present invention, according to a side view; -
FIG. 5b shows the spout ofFIG. 5a , according to a cross-sectional view; and -
FIG. 6 shows a diagram of a mold for making the spout according to an embodiment of the present invention. - With reference to the accompanying drawings,
reference numeral 1 indicates a flexible thin-walled packaging, comprising apackaging body 2, comprisingthin walls 4 facing each other, and aspout 6, sealingly fixed, preferably by welding, between thethin walls 4 of thepackaging body 2. - The
packaging 1 is provided with asacrificial closure 200 applied to the outlet mouth of thespout 6. - According to a first embodiment, the
sacrificial closure 200 is applied reversibly to thespout 6, that is, so that it may be separated from the spout to have access to the outlet mouth; for example, said sacrificial closure is a cap applied by pressure to the spout and separable from it. - According to a further embodiment, the
sacrificial closure 200 is irreversibly applied to the spout, i.e. in such a way that it must be at least partially torn to allow access to the outlet mouth; for example, said sacrificial closure is a cap applied by pressure to the spout so as not to be removable and comprises a tear-resistant membrane. - According to the sterilization process, a
packaging 1 is produced on a production site. - Subsequently, the
sacrificial closure 200 is applied to theempty packaging 1, preferably at the production site. - The empty packaging—sacrificial closure assembly, for example after being transported from the production site to a sterilization site—undergoes a sterilization process, typically by ionization by gamma or beta rays, obtaining a sterilized assembly.
- According to an alternative embodiment, the
sacrificial closure 200 is applied to thespout 6 at the sterilization site, however, before carrying out the sterilization process. - The sterilized assembly, preferably after being transported to a filling site, is sent to a filling machine, where at least part of the
spout 6 passes through a sterile chamber. - In said sterile chamber, the
sacrificial closure 200 is tampered with so as to access the outlet mouth of thespout 6. - The
packaging 1 is then filled through the outlet mouth of the spout. - If the
sacrificial closure 200 is irreversibly applied to thespout 6, saidsacrificial closure 200 is at least partially torn, for example by breaking a surface membrane; thepackaging 1 is then filled through the outlet mouth of the spout. - Subsequently, according to an embodiment of the invention, while the full packaging is still in the sterile chamber, a definitive closure, for example a cap with a thread, is applied to the
spout 6; in this way a filled packaging—final closure assembly for marketing is obtained. - According to an alternative embodiment, while the full packaging is still in the sterile chamber, a temporary closure is applied to the spout, for example consisting of the sacrificial closure; a filled packaging—temporary closure assembly is thus obtained, to which the definitive closure is subsequently applied outside the sterile chamber. According to such embodiment variant, the definitive closure is suitable for engaging with the temporary closure, so that, once the definitive closure has been removed, the temporary closure is also removed from the spout.
- The
spout 6 extends mainly along a main axis X, between alower end 8 and anupper end 10. - At the
lower end 8, thespout 6 comprises a connectingportion 12, usually defined as a “welding boat”, intended for welding between thethin walls 4 of thepackaging body 2. - Preferably, the
spout 6 further comprises alower plate 14, which extends on an imaginary plane orthogonal to the main axis X, adjacent to the connectingportion 12, and anupper plate 16, parallel to and separated from thelower plate 14. - The
spout 6 further comprises atube 18, provided with an outer surface 18 e, which protrudes from theupper plate 16 and extends to theupper end 10, where there is anoutlet mouth 20. - On the outside of the tube 18 a
thread 22 is preferably provided for screwing the final closure. - Internally, the
spout 6 has a through dispensingduct 24 which extends from theoutlet mouth 20 to thelower end 18, having a central axis coinciding with the main axis X of thespout 6. - The
sacrificial closure 200 comprises askirt 202 consisting of an annular wall having a predefined axial height, provided with an inner diameter such as to allow said skirt to be fitted on the outer surface of thetube 18. - Preferably, the
skirt 202 comprises aseal 204 consisting of a lip protruding radially internally, suitable for achieving an airtight seal by adhering to the outer surface of thetube 18. - Furthermore, the
sacrificial closure 200 comprises abase 204 which closes theskirt 202 at the top; in the embodiment in which the sacrificial closure is irreversible, saidbase 204 is a tearable membrane. - The
spout 6 is made of a single piece of plastics material, preferably by injection molding. - In particular (
FIGS. 5a and 5b ), thespout 6 consists of two portions: afirst portion 602, comprising the connectingportion 12, eventually thelower plate 14 and theupper plate 16, and alower portion 182 of thetube 18, and asecond portion 604 comprising anend portion 184 of thetube 18, provided with theoutlet mouth 20. - The
spout 6 is obtained in a single piece by injection molding, using for example a mold assembly 300 (FIG. 6 ). - The
mold assembly 300 comprises a first half-mold 302 having a first half-cavity 302 a and a second half-mold 304 having a second half-cavity 304 a. The two half-molds cavities - The
first portion 602 of the spout is obtained by filling the first cavity. At said first contact plane P1, on thefirst portion 602 of thespout 6 it is possible to see a first dividing line L1. - Preferably, said first dividing line L1 is contained on an imaginary plane which also contains said main axis X.
- The
mold assembly 300 further comprises anannular insert 306, having asecond cavity 306 a which has complete annular extension; theinsert 306 couples with the two half-molds second cavity 306 a is arranged astride the two half-molds - The
second portion 604 is obtained by filling thesecond cavity 306 a. - At the connection between the
first portion 602 and thesecond portion 604, a second circumferential dividing line L2 may be seen, having a predefined distance H2 from theoutlet mouth 20. - The second dividing line L2 lies on an imaginary plane P2 orthogonal to the main axis X.
- Furthermore, between the
first portion 602 and thesecond portion 604, on the outer surface 18 e of thetube 18, a smoothannular band 606 is defined, free of any flanges, projections, protrusions and the like. - The second dividing line L2 is contained in said
band 606, dividing it into anupper band 606 a, towards theoutlet mouth 20, and alower band 606 b, on the opposite side. - Finally, the
mold assembly 300 comprises amale element 308 which crosses theinsert 306 and passes through thesecond cavity 306 a and through the first cavity, so as to create the inner cavity of the spout. - The
skirt 202 of thesacrificial closure 200 cooperates with the outer surface 18 e of thetube 18 to seal the inlet mouth, along a sealing region having an axial distance H from saidoutlet mouth 20, wherein said sealing distance H is less than or equal to said division distance H2 between the second dividing line L2 and theoutlet mouth 20. - In other words, the
sacrificial closure 200 engages thetube 18 only at thesecond portion 604, i.e. only on the outer surface of theend portion 184 of thetube 18. - In particular, the
seal 204 of theskirt 200 operates on the outer surface of theend portion 184 of thetube 18 at a sealing distance H from theoutlet mouth 20, wherein said sealing distance H is less than the division distance H2 of the second dividing line L2 from theoutlet mouth 20. - This allows the sealing between the
skirt 202 and the outer surface 18 e of thetube 18 to be achieved on a smooth surface, without dividing lines which could compromise the sealing itself, to the advantage of maintaining said seal. - Preferably, moreover, the
thread 22 is made on thelower portion 182 of thetube 18. - Innovatively, this allows an excellent seal to be obtained between the sacrificial closure and the spout tube, and to preserve it for the subsequent steps of the production process.
- It is clear that a man skilled in the art may make changes to the invention described above in order to meet incidental needs, all falling within the scope of protection defined in the following claims.
