DESCRIPTION OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates to a sterile and extendable shelf life (ESL) container, particularly a cardboard carton. [Prior Art] In a non-sterile container, it is known to use a carton fitting to extend through the wall of the cardboard cardboard. These fittings provide an injection spout and provide a resealable closure, such as a threaded injection spout and upper cover. It is generally made of injection molded plastic. The accessory may also provide a security package such as a detachable security strip that links the lower edge of the upper cover to the body of the accessory. A pull ring removable film is typically provided in the spout. Typical fittings have a basic flange and a cylindrical spout. This accessory is inserted through the hole cut in the upper side of the carton as a fully assembled component equipped with a top cover. The fitting penetrates the aperture from the inside of the opening during the filling procedure. A substantial flange greater than the diameter of the aperture is maintained in the carton. The base flange is welded to the carton using ultrasonic welding and the fitting is secured in place. This type of accessory can be extended to allow the mountain top cardboard box to be resealable. It is generally used for fresh milk and fresh juice, but it is not packaged aseptically. Aseptic packaging In aseptic filling, the UHT program is used to fill the pre-treatment product. The product is heated at a high temperature (140 seconds) for a very short time (4 seconds) and then cooled to between room temperature and 4 ° C. Once cooled, the product must be maintained in sterile conditions and not exposed to ambient air or In bacteria, the carton and accessories must also be cleaned and sterilized, typically using hydrogen peroxide or peracetic acid, which will evaporate from the assembly later. Then fill the carton and seal it in a sterile environment. The package must also be adequate. Tight seal to avoid reinfection. This procedure is very effective for products that offer extended shelf life. The cost of filling is important. 200523178 ESL packaging covers other procedures 'eg micro-data to ensure minimal microbial presence In this product, the most important feature of the aseptic and ESL carton is the presence of a continuous barrier. This layer needs to avoid the penetration of bacteria, microorganisms, yeast or sputum spores into the crying, and provides a barrier to isolation. Pre-cutting holes in the blanks of the carton of the accessory is obviously impossible. The carton used in aseptic packaging is generally composed of several layers. 'There is a multi-layered S-heat bacteria package I. From the outside to the inside: polyethylene, adhesive, paper, drying agent, enamel, drying agent and polyethylene. This provides a barrier. A layer of the primer is used to dry the material, and a layer of polyethylene is used to provide a surface coating. The (four) structure described is formed into a cardboard. The separator may be selectively made of EVOH. The original aseptic carton is a synthetic cardboard tetrahedron and later shaped as a monument, which is difficult to open 'and cannot be re-sealed. The current aseptic carton provides a carton with a resealable closure, for example with a screwed lid closure Cardboard carton. In order to maintain the barrier, two methods are applied. In the first method, 'the cardboard blank is cut in the outer layer of the synthetic cardboard before the laminated blank is laminated with the inner layer before the cardboard blank is laminated. a hole. The fitting then supplies m to the outside of the carton, and the I must pass through the isolation layer to cut, tear or perforate the inner layer. In the second method, the synthetic cardboard is creased and Weaken' does not need to penetrate the barrier at the carton assembly. The cutting, tearing or perforating mechanism must then break all layers of the synthetic cardboard. A number of different designs have been proposed for this mechanism. These ranges from the pivot rod, the downward drive tooth through the ratchet of the cardboard, and A thorough perforation system that requires the user to push down the spout with a thumb. An example of such a rear application carton accessory is described in EP-A-1, 127798 (retrial), which teaches a cam drive mechanism, and 〇98.41452 (Tetra Laval), which teaches the ratchet mechanism and provides anti-counterfeiting marks in 200523178. Many other commercially available accessories come from manufacturers such as SIG Combibloc GmbH & Co KG (www.sigcombibloc.com) and Bericap GmbH & Co (http://www.bericap.com)· Technical issues All of these accessories are subject to technical problems, including the considerable strength and relatively complex manufacturing, installation and use of the package to be opened, especially consisting of multiple parts. Accessories. Arrangement problems are a particular problem in post-application accessories. Since the accessory must be adhered to the container, there is a separate risk in shipping. This external application also makes these closures susceptible to counterfeiting. The use of these closures often does not consciously create additional problems with customer education. Without the conventional fittings retaining the barrier layer in the synthetic cardboard carton, the present invention addresses the provision of a continuous barrier layer having a resealable injection nozzle closure by providing the barrier layer in the closure itself. It can be inserted into a pre-cut hole in a non-sterile carton. However, in sterile/ESL content, exposure of bare metal to a plurality of contents of a liquid that is packaged in a sterile manner, such as a strong acid product, is unacceptable. This is due to the tendency of such products to have a shelf life of more than six to nine months: the metal will be oxidized. Therefore any exposed metal must avoid contact with the contents of the sterile carton. Therefore, the application of a metal is not sufficient: even the coated metal to the basic flange of the carton fitting, any exposed cutting edges are susceptible to long-term oxidation. It is known to make cartons from synthetic cardboard blanks to avoid such contact in the structural seams. In general, to form the seam, an inner cardboard layer is folded outwardly and overlaps an outer layer such that the edges of the metal of the barrier layer are protected from contact with the contents. The seam is welded by ultrasonic or induction heat sealing. This produces acceptable results. Applying a removable, tearable metal seal across the top end of the fitting spout avoids the presence of a plug in the upper cap to satisfy the repetitive seal and passes through the hole 200523178 and the spout wall through the base The flange leaves an important breach in the gas barrier. Preferably, the barrier layer is continuous in the basic flange of the fitting, which is one of the solutions described in U.S. Patent 4,948,015 (Kawajid). The described assembly has a base flange provided with a recess in which a film having a gas barrier property is securely disposed. It has been suggested that the film can be a laminate structure comprising a layer of polyethylene, aluminum and polyethylene. The barrier layer has a peripheral edge that is covered by the material of the film. It has been suggested to incorporate a splicing technique into the accessory. Basically this is for Kawajiri to address the technical issues discussed above. However, this is not feasible for the following reasons: • The actual, high-capacity, low-cost manufacturing of multilayer films consisting of an entire embedded metal layer (without exposed aluminum edges) is unknown in the industry and there is no description. ♦ Inserting this lightweight metal disc will be a slow procedure that requires careful replacement of the disc into the module. ♦ In order to place the disc into the groove, it is most unavoidable that the crack will be generated in the groove around the ring, and this will make the fitting unsuitable for aseptic use, and the crack cannot be sufficiently sterilized before use. The inability to kill bacteria hidden in cracks is a major problem, making any package prone to non-probiotic bacteria, resulting in a product that has a shelf life of only a few days, rather than a non-refrigerated condition, which is currently stored in sterile form for several months. the term. SUMMARY OF THE INVENTION According to the present invention, an unsolved technical problem left by KawajiH is solved by providing a fitting comprising: a basic flange and a hollow injection nozzle; the removable portion is located at the injection nozzle base And the upper cover, the resealable closure of the injection sneeze; and the isolation metal, both sides of which are covered with a plastic layer extending across the basic flange, characterized in that the metal is combined to the accessory 200523178 _ $ The exposed cutting edge is green, and the edge of the metal is used to avoid the contact in the contact with the accessories that have been combined with the accessories, and the combination of the contents of the life is combined with the convexity. The rim may be of various types (4), and the embossing is carried out by embedding it in the embossed edge of the flange before it is sealed, or wrapping it around the peripheral edge of the flange. η' The edge of the metal is aged into the base flange. It is not possible to contaminate the product by entering the gold stalker into the plastic. Since the barrier layer in the cardboard has overlapped with the barrier metal applied to the base flange, there is no interruption in the barrier layer. The accessory can be manufactured by a method comprising the steps of placing a metal layer on a surface of a plastic layer on a surface of the component, the receiving wall protruding from a first surface of the basic flange of the component, the fitting having a hollow nozzle Extending from the opposite surface and securing the metal to the flange causes the wall to pass through the dome. *The assembly of the tamping combination can be inserted into the pre-cut hole in the blank of the cardboard box before the filling, and the inlay of the metal edge performs the same procedure as welding the flange to the cardboard. . Alternatively, the present invention provides an accessory comprising: a base flange having a first surface; and a hollow injection nozzle protruding from a surface relative to the first surface; a movable portion: located at the injection nozzle base And the upper cover is reproducibly closed to the a 4 'main inlet nozzle, characterized in that: the two sides of the isolation metal are covered with a plastic layer, covering the first surface of the flange, so that the metal extends to surround the injection On the opposite surface of the spout. In this different configuration, the ultrasonic welding of the fitting to the carton period = the cutting edge of the metal avoids contact with the contents of the valley when it is sealed to the cardboard wall. This seal has exactly the same structure and integrity as a seal 70 at any other location on the cardboard carton. The bulk of the isolation layer in this structure 200523178 is continuous, with only 4 inner polyethylene layers between the two metals, and is not the same as the moderate thickness of the basic flange previously changed. Preferably, if the requested accessory is used in any shape of cardboard carton, it should be understood that this type of accessory can also be used in the mouth of an airtight bottle, such as a barrier PET or multilayer polyolefin bottle, applied to Coated steel or aluminum cans or cans, or applied to single or multi-layer plastic containers for heat forming, injection molding or blow molding. [Embodiment] Overview A carton fitting 2 is made of a basic flange 4 having an upright injection nozzle 6 closed by an upper cover 8. The accessory 2 is a two-shot molded plastic component. The spout 6 includes a hollow cylindrical spout in the base having a removable portion 10. The removable portion 10 is a plastic disc that is bonded to the remainder of the basic flange 4 by the weakened portion 12. A tab 14 is attached to the removable portion 10 so that the removable portion can be removed. As presently described, this accessory is substantially similar to the carton accessories known in the industry for use in standard cardboard cartons. Any design features applied to this accessory can be incorporated into the accessories of the present invention. However, the fitting of the present invention is intended to be used in a container for providing a barrier layer. As shown in the first figure, the fitting is inserted into the pre-cut, hole 20 in the synthetic cardboard carton wall 22. The fitting 2 can also be combined to the opening mouth of the isolating PET or polyolefin separator bottle, or any other gas tight container, such as a tinplate can be made of a single or multi-layer coated aluminum coated steel surface layer. , or thermoforming, =

A metal disc 30 is sealed to the underside of the base flange 4 and the removable portion 1 2005 200523178 side. Instead of a solid dish, the removable portion ίο can be constructed as a ring-shaped frame typically having a heart and a three-point star structure. This frame can be joined to the flange 4 by a weakened bridge. This will reduce the total weight of the accessory. The earthen 5th metal plate 30 series is cut from aluminum metal, and the two sides are covered with a plastic layer of general olefin, polypropylene or PET, which is combined with other plastic components. The base flange 4 is spliced into the soil region A to the carton wall 22 by an induction heat seal or ultrasonic device. A receiving wall 32 surrounds the peripheral edge of the base flange 4. In the first figure, it is shown that the receiving wall 32 has been deformed inwardly beyond the peripheral edge of the metal disc 30 to prevent the contents of the container from being exposed to the edges of the aluminum layer in the metal disc 30 that has been covered on both sides. The carton structure 6 is formed of a multi-layer material comprising a gas barrier layer 40. This barrier layer can be aluminum metal or EVOH or any other suitable material. The barrier layer is bonded to a cardboard layer by an adhesive layer which is coated on each side by a polyethylene coating. The synthetic cardboard can also be of other construction. Closed Structure A possible construction of the upper cover and injection spout has been described in WO 99/61337 (Spreckelsen McGeough), which also shows how a metal can fit into a basic flange. However, in this document, the free metal edge of the metal is exposed. Spreckelsen McGeough also showed a pull tab on the top cover. It should be understood that the thread of the upper cover 8 as shown is suitable for closing the injection nozzle 6. The upper cover 8 is shown with a plug 42 received in one of the openings of the spout 6 to ensure an effective repetitive seal. Threads 44, 46 are formed on the outer wall of the spout of the injection spout 6 and on the inner facing wall of the upper cover 8 to screw the upper cap to the spout. Sealing the Edge of the Metal 200523178 The basic feature of the fitting of the present invention is that when the fitting is assembled, the metal edge of the metal avoids contact with the contents of the container during use. The fitting 2 is preferably pre-sealed to the metal 30 prior to installation in the container. In the first and second embodiments, the metal disk 30 is located in the receiving wall 32 and is vertically attached to the base flange 4 prior to combining the metal to the spout 6, as shown in the second figure. During assembly, a tool is used to press the receiving wall 32 through the edge of the metal dish during the induction heat sealing process. The receiving wall 32 is thus the sacrificial portion of the spout structure and the plastic from which the material is made is effectively melted through the edge of the metal to seal the exposed metal edge. Another structure of the receiving wall 32 is shown in the third A and third B views. In this configuration, the wall 32 has a weakened portion 50 located in the intermediate annular region. Once the metal disk 30 is inserted into the receiving wall 32, the weakened portion 50 allows the terminal end 52 of the wall to be deformed inwardly through the metal to maintain it in position to ensure that the plastic of the sacrificial receiving wall 52 flows through and Cover any exposed metal edges. Another method of sealing the metal edge of the metal 30 is shown in the fourth figure. In this embodiment, the metal 30 is larger than the diameter of the base flange and overlies the entire lower first surface 54 of the base flange 4 about the free edge and the second edge of the base flange. The folded edge terminates inwardly in the annular region A, wherein the base flange 4 is welded to the container 22. In the embodiment of the fifth embodiment, the metal disc 30 has edges that fold up and inward before being welded to the base flange 4. This folding step can be accomplished by a suitable forming tool during placement of the metal onto the base flange 4. The periphery of the base flange 4 is provided with a fixed wall 34 to secure the folded metal disk in place prior to sealing. Manufacturing Method Before the accessory is assembled to the cardboard carton, the carton accessory 2 is assembled to the metal plate 30 in advance 12 200523178, and the metal is welded in place by an induction heat sealing process. The combination of the cardboard carton is like a standard non-sterile package and will not be described in detail herein. Ultrasonic welding can be applied as another alternative to induction heat sealing the metal to the base flange 4. The metal may also be secured to the flange by an adhesive means. In the embodiment of the fourth embodiment, the outer peripheral surface of the metal may be coated around the base projection 4 to secure the metal to the spout 6. While it is possible to take additional bonding steps prior to installation in the carton, it is not necessary to utilize this embodiment. If the fitting 2 is inductively heat sealed to the carton, the metal 3() will be welded to the base flange at this time. In the embodiment of the fourth embodiment, the structure is established at the same time as the edge between the edge of the metal and the wall 22, and the other seams elsewhere in the cardboard carton of this type are identical. Continuously the barrier layer Once the fitting 2 is welded into the hole 2 in the cardboard carton wall 22, the barrier layer is replaced by the metal 30 to create a continuous barrier layer having a layer of 4 turns in the cardboard carton. Thus, the ease of combination of the use of a non-sterilely packaged carton accessory combines with the integrity of the barrier provided by conventionally used accessories for aseptic packaging. Customer Use In use, the customer can remove the upper cover 8 by loosening to open the package to pull the tab 14. The removable portion can then be removed by using the pull ring 14. Since the metal 30 is welded to the entire base flange 4 containing the removable portion 1 , pulling the tab pulls the metal and allows access to the contents of the container. If desired, teeth can be formed in the lower surface 54 of the base flange 4 to promote tearing of the metal as described in Spreckelsen McGeough, supra. If the metal cannot be cracked by removing the removable portion 1 ,, it is easy to manually punch the metal layer. 13 200523178 Although a pull tab has been shown, any other conventional mechanism can be used in the spout to remove the removable portion and tear the metal to allow access to the contents.
