1311971 九、發明說明： 【發明所屬之技術領域】 本發明關於一種無菌及可延長保存期限(ESL)容器，尤其 是硬紙板紙盒。 【先前技術】 在非無菌容器中，已知使用紙盒配件延伸穿過硬紙板硬 紙板之壁。這些配件構成提供一注入喷口，並提供可重複密 封關閉，例如螺紋注入喷口與上蓋。其一般由射出成型塑膠 製成。該配件亦可提供防偽包裝例如可斷開的防偽帶連結該 上蓋之較低邊緣至該配件之本體。拉環可移除膜通常提供於 該喷口中。典型的配件具有基本凸緣及圓柱形喷口。 此配件如同配備有上蓋之完全組合元件般地透過該紙盒 上方切割之孔插入。該配件於該填裝程序期間自該開口上方 内側穿透該孔。大於該孔直徑之基本凸緣維持於該紙盒内。 使用超音波焊接將該基本凸緣焊接至該紙盒，並固定該配件 於適當的位置上。此類型的配件可延伸用於讓山形頂硬紙板 紙盒可重複密封。其一般用於新鮮的牛奶與新鮮的果汁，但 並非以無菌方式包裝。 無菌包裝 在無菌填裝中，UHT程序用於填裝前處理產品。該產品 於非常短時間（4秒）的高溫（140°C)，接著冷卻至室溫與4°C 之間之溫度。一旦冷卻，該產品必須維持於無菌條件中，且 無法暴露於環境空氣或細菌中。該紙盒與配件亦必須清理並 殺菌，一般利用雙氧水或過醋酸，其在稍後會從該組件蒸發。 接著填入該紙盒，並於無菌環境中密封。該包裝亦必須足夠 緊的密封，以避免再次感染。此程序對於提供延長保存期限 的產品是很有效的。填裝的成本是很重要的。 1311971 ESL包裝涵蓋了其他程序，例如微過濾，以確保最小微 生物存在於該產品中。 無菌與ESL紙盒之最重要特徵在於連續隔離層的存在。 此層需要避免細菌、微生物、酵母或似簟孢子穿入該容器中， 並提供氣體隔離屏障。現有紙盒配件之使用需要於該紙盒空 白處中預先切割孔，乃明顯地係不可能。 使用於無菌包裝中的紙盒一般由若干層構成。在一範例 中，有多層製成該無菌包裝。其從外至内為：聚乙烯、粘著 劑、紙、粘著劑、鋁箔、粘著劑及聚乙烯。該鋁箔提供一隔 離層。該粘著劑層用以將該等材料粘在一起，而聚乙烯層用 以提供表面塗覆。所描述的這些層狀結構為合成硬紙板。該 隔離層可選擇性地由EVOH製成。 該原本無菌紙盒為合成硬紙板四面體，且稍後為磚形， 很難打開，且無法重覆密封。現在的無菌紙盒提供紙盒配件， 可重複封閉，例如具有螺紋上蓋閉合之硬紙板紙盒。為了維 護該隔離層，應用兩種方法。 在第一方法中，在硬紙板空白處於隔離層與内層層壓之 前，在合成硬紙板空白處之外紙與塑膠層中切割一孔。該配 件接著供應至該紙盒之外部，且必須併入一機制透過該隔離 層與内層切割、撕裂或打孔。在第二方法中，使合成硬紙板 起折痕並加以弱化，不需於該紙盒配件放置處穿透該隔離 層。該切割、撕裂或打孔機制接著必須打破該合成硬紙板之 所有層。許多各種不同的設計已為此機制加以提出。這些範 圍自樞軸桿、向下驅動齒通過硬紙板之棘齒、及需要使用者 用大拇指向下推入該喷口的徹底打孔系統。此種後應用紙盒 配件的範例描述於EP-A-1,127798(再審）中，其教示一凸輪驅 動機制，及WO 98.41452 (Tetra Laval)，其教示棘齒機制，並 1311971 提供防偽標記。許多市面上其他可應用配件來自於製造商， 例如 SIG Combibloc GmbH & Co KG(www.sigcombibloc.com) 及 Bericap GmbH & Co (http://www.bericap.com). 技術問題 這些所有的配件皆遭遇技術問題，包含需要開啟包裝的 相當力量及相對複雜的製造、安裝與使用，尤其是由多個部 分組成的配件。排列問題在後應用配件中是一個特殊的問 題。由於該配件必須黏在該容器上，在運送中存在分開的風 險。該外部應用亦使這些封閉物容易受到仿冒。這些封閉物 的使用常常不自覺產生顧客教育的額外問題。 不用這些習知配件保留該隔離層於該合成硬紙板紙盒 中，本發明藉由提供該隔離層於該封閉物本身中，解決提供 具有可重複密封注入噴口封閉物之連續隔離層之方法，使其 可插入非無菌紙盒之預先切割孔中。 然而在無菌/ESL内容物中，將裸露金屬暴露於許多以無 菌方式包裝的液體的内容物例如強酸產品中，是不可接受 的。這是由於此類產品具有一傾向：超過六至九個月的保存 壽命：會氧化該金屬。因此任何裸露金屬必須避免接觸該無 菌紙盒的内容物。因此應用一金屬並不足夠：甚至已被覆的 金屬至紙盒配件之基本凸緣，任何暴露的切割邊緣會容易受 到長期氧化。需要從合成硬紙板空白處製造紙盒以避免在該 結構接缝中有此種接觸係為已知。一般而言，欲建立此接缝， 一内硬紙板層向外摺疊，並重疊一外層，使得該隔離層金屬 之邊緣避免與該内容物接觸。該接缝係由超音波或感應熱密 封加以焊接。這可產生可接受的結果。 應用一可移除、可撕下的金屬密封跨過配件噴口頂端， 可避免該上蓋内之插塞的存在，以滿足重複密封，並於該孔 1311971 與該噴口壁中透過環繞該噴口的基本凸緣留下—個重要的裂 口於該氣體屏障中。

該上蓋與注入喷口之可行的結構已描述於W099/61337 (SpreckelsenMcGeough)中，其亦顯示一金屬如何可能置入一 基本凸緣中。然而，在該文件中，會暴露該金屬之自由金屬 邊緣。Spreckelsen McGeough亦顯示一拉片設於上蓋上。應 了解如圖所示上蓋8之螺紋適用於閉合該注入喷口 6。該上蓋 8顯示為具有一插塞42接收於該喷口 6之一開口嘴中，以確 保有效的重複密封。螺紋44、46形成於該注入喷口 6之喷口 之外壁上，並位於該上蓋8面向内之壁上，以使該上蓋旋緊 於該噴口上。 11 1311971 密封該金屬之邊緣 本發明之配件之基本特性為當組合該配件時，該金屬之 金屬邊緣於使用中避免接觸容器之内容物。該配件2最好於 安裝於該容器中之前預先密封於該金屬30。在第一圖與第二 圖之實施例中，該金屬碟30位於接收壁32中，其在組合該 金屬至該喷口 6前，垂直依附於該基本凸緣4,如第二圖所 示。在組合期間，使用一工具在感應熱密封過程其間透過該 金屬碟之邊緣按壓該接收壁32。該接收壁32因而係該喷口結 構之犧牲部分，且製成此材料之塑膠有效的透過該金屬之邊 · 緣熔化，以密封該暴露的金屬邊緣。 該接收壁32之另一結構顯示於第三A圖與第三B圖中。 在此配置中，該壁32具有弱化部份50位於中間環狀區域中。 一旦該金屬碟30插入該接收壁32中，該弱化部份50允許該 壁之終端52透過該金屬向内變形，以將其維持於適當位置， 以確保此犧牲接收壁52之塑膠流過並被覆任何暴露的金屬邊 緣。 另一密封該金屬30之金屬邊緣之方法顯示於第四圖中。 在此實施例中，該金屬30大於該基本凸緣之直徑，且繞著自 Ο 由邊緣與該基本凸緣之第二邊緣上，包覆該基本凸緣4之整 個較低第一表面54。該摺疊邊緣向内終止於該環狀區域A， 其中該基本凸緣4焊接至該容器22。 在第五圖之實施例中，於焊接至該基本凸緣4前，該金 屬碟30具有向上及向内摺疊之邊緣。此摺疊步驟可於放置金 屬至基本凸緣4上之期間，藉由一適當形成工具加以完成。 該基本凸緣4之週邊提供有固定壁34，以在密封前固定該摺 疊金屬碟於適當位置。 製造方法 12 1311971 於該配件組合至該硬紙板紙盒之前，該紙盒配件2預先 組合至該金屬碟30，且該金屬由感應熱密封程序焊接於適當 位置。該硬紙板紙盒之組合如同標準非無菌包裝，在此將不 詳加描述。如同感應熱密封該金屬至該基本凸緣4之另一選 擇，可應用超音波焊接。該金屬亦可由黏著裝置固定於該凸 緣。在第四圖的實施例中，可依賴環繞著該基本凸覆4包覆 該金屬之外週邊表面，以固定該金屬至該喷口 6。雖然可在安 裝於該紙盒中之前採取另外的結合步驟，利用此實施例並非 必須的。若該配件2係感應熱密封至該紙盒，該金屬3 0會於 此時焊接至該基本凸緣。 在第四圖的實施例中，建立於該金屬30之邊緣與該壁22 間之密封與此類型的硬紙板紙盒中其他處的其他接缝上的結 構完全相同。 連續該隔離層 一旦該配件2焊接至該硬紙板紙盒壁22中之孔20中， 該隔離層由該金屬30取代，建立一具有層40之連續隔離層 於硬紙板紙盒中。因此，使用非無菌包裝之紙盒配件之容易 組合優點結合無菌包裝傳統使用的後應用習知配件提供的隔 離層之完整性。 顧客使用 在使用中，顧客可藉由鬆開而移除該上蓋8以打開該包 裝，以拉取該拉環14。該可移除部份10接著可藉由使用該拉 環14加以移除。由於該金屬30焊接至整個基本凸緣4包含 有該可移除部份10，拉開該拉環會撕裂該金屬，並允許存取 該容器内容物。若有需要，可形成齒狀物於該基本凸緣4之 較低表面54中，以促進撕裂該金屬，如上述之Spreckelsen McGeough中所述。若該金屬無法藉由移除該可移除部份10 13 1311971 而裂開，以人工方式對此金屬層打孔是很容易的。 雖然已顯示一拉環，任何其他習知機制可使用於該喷口 中，以移除該可移除部份並撕裂該金屬，以允許存取該内容 物。1311971 IX. Description of the Invention: [Technical Field of the Invention] The present invention relates to a sterile and extendable shelf life (ESL) container, especially 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 cooled to a temperature between room temperature and 4 ° C in a very short time (4 seconds) at a high temperature (140 ° C). Once cooled, the product must be maintained in sterile conditions and not exposed to ambient air or bacteria. The carton and accessories must also be cleaned and sterilized, typically with hydrogen peroxide or peracetic acid, which will evaporate from the assembly at a later time. The carton is then filled and sealed in a sterile environment. The package must also be tightly sealed to avoid reinfection. This procedure is very effective for products that offer extended shelf life. The cost of filling is very important. 1311971 ESL packaging covers other procedures, such as microfiltration, to ensure that minimal microbes are present in the product. The most important feature of sterile and ESL cartons is the presence of a continuous barrier layer. This layer needs to prevent bacteria, microorganisms, yeast or sputum-like spores from penetrating into the container and providing a gas barrier. The use of existing carton accessories requires prior cutting of the holes in the carton blank, which is obviously not possible. Cartons used in aseptic packaging generally consist of several layers. In one example, multiple layers are made into the aseptic package. From the outside to the inside: polyethylene, adhesive, paper, adhesive, aluminum foil, adhesive and polyethylene. The aluminum foil provides a barrier layer. The adhesive layer is used to bond the materials together and the polyethylene layer is used to provide surface coating. The layered structures described are synthetic cardboard. The spacer layer can be selectively made of EVOH. The original aseptic carton is a synthetic cardboard tetrahedron and later brick-shaped, which is difficult to open and cannot be re-sealed. Today's aseptic carton provides a carton accessory that can be reclosed, such as a cardboard carton with a threaded lid closed. In order to maintain the barrier, two methods are applied. In the first method, a hole is cut in the paper and plastic layer outside the blank of the synthetic cardboard before the cardboard blank is laminated with the inner layer and the inner layer. The fitting is then supplied to the exterior of the carton and must incorporate a mechanism to cut, tear or perforate through the barrier layer and the inner layer. In the second method, the synthetic cardboard is creased and weakened without penetrating the barrier at the place where the carton fitting is placed. This 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 range from the pivot rod, the downward drive tooth through the ratchet of the cardboard, and the thorough perforation system that requires the user to push the thumb down into the spout. An example of such a rear application carton accessory is described in EP-A-1,127798 (review), which teaches a cam drive mechanism, and WO 98.41452 (Tetra Laval), which teaches the ratchet mechanism and 1311971 provides an anti-counterfeit mark. 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 for multiple parts. 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 1311971 and the spout wall through the base The flange leaves an important breach in the gas barrier. The piece has a basic flange, provided that the best (four) separation layer is continuous with the configuration of the basic convex = rr, 94M15 (Kaw coffee) towel - solution. The description of the groove, which has a gas barrier layer Μ Μ 兹 兹 η 札 札 ( (10) 赝 槿 勺 ' spoon i ancient: " has been placed in it. It has been suggested that the film can be a laminate of 3 A, ethylene, and polyethylene. The barrier layer has a peripheral edge :: film:: material cover. It has been suggested to incorporate this film into the two by insert molding techniques! ^ This is for Kawajln to address the technical issues discussed above. However, this design is not feasible for the following reasons: • = does not reveal any practical, mass-produced, and low-cost method of making a layer of silk that can be manufactured to include a fully embedded layer of inscription (ie == The multilayer film of the outer edge), the manufacturing method. The second molding of this lightweight metal disc will be a slow procedure that requires careful replacement of the disc in the main talent group. • Placed in the groove, the most inevitable is that the crack will be created in the groove' and this will make the fitting unsuitable for aseptic use, in the middle of the ground (4). Unable to kill the guide hidden in the cracked bacteria: a major problem that makes any package easy to produce a non-necked shelf life" only a few days, rather than months of non-refrigerated conditions the term. SUMMARY OF THE INVENTION The invention provides an unsolved technical problem left by Ka'iri. The accessory includes: a basic flange and a hollow injection, and a secret: = share, located in the Injecting into the mouth base; and the upper cover, for injecting the spout, and separating the metal, the two sides are covered with a plastic layer, 1311971 extending across the basic flange, characterized in that the metal is combined to the The accessory has an exposed cutting edge previously, and the edge of the metal is prevented from being bonded to the flange in a manner that contacts the contents of the container in which the accessory has been assembled. The edge can be sealed in a variety of different ways, such as by It is embedded in the plastic of the flange, folded underneath the flange, or wrapped around the peripheral edge of the flange. Preferably, the edge of the metal is embedded in the base flange. By embedding the edge of the metal into the plastic, it does not contaminate the product. Since the barrier layer in the cardboard carton overlaps the barrier metal applied to the base flange, there is no interruption in the barrier. The method can be manufactured by a method comprising: placing a metal having a plastic layer on each surface into a receiving wall, the receiving wall protruding from a first surface of the basic flange of the fitting, the fitting having a hollow nozzle from the relative Extending the surface and securing the metal to the flange such that the wall is sealed through the edge of the metal disc. The complete combination of accessories can be inserted into the pre-cut hole of the synthetic cardboard carton blank before filling. The embedding of the metal edge performs a portion of 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 spout, relative to the a surface of the first surface protrudes; a removable portion is located in the base of the injection nozzle; and an upper cover for resealably closing the injection nozzle, wherein the two sides of the isolation metal are covered with a plastic layer a first surface of the flange such that the metal extends to an opposite surface surrounding the injection nozzle. In this different configuration, the ultrasonic welding of the accessory to During the carton, the cutting edge of the metal avoids contact with the contents of the container when it is sealed to the cardboard wall. This seal has the same structure and integrity as 1311971 anywhere else on the cardboard carton. The majority of the isolation layer has only the inner polyethylene layer on the two metals and the enthalpy changes the basic thickness of the basic edge. 5, if the requested accessory is used for any shape of the cardboard carton to solve this problem Types of accessories can also be used in the mouth of airtight bottles; for example, from pet or multi-layered polystyrene bottles, applied to coated steel or rotary or cans: 1 application to heat formation, injection molding or blow molding Layer or Multilayer Plastic [Embodiment] Overview - The carton fitting 2 is formed by a basic flange 4 which is an upright injection nozzle 6 in which the upper cover 8 is closed. Deep, there are two injection molded plastic components from the fitting 2 system. The mouthpiece 6 comprises a hollow cylindrical spout located in the base, 1 having a septum. The removable portion 1G is a plastic disc that is bonded to the ί portion by weakening the portion. - The pull ring 14 is attached to the transfer port P for injury 10 so that the removable portion can be removed. As stated, this accessory is substantially similar to the industry's == piece, any design on this accessory. However, the accessory of the present invention is intended to provide the isolation layer - the figure shows the assembly of the accessory Pre-(4) in the cardboard box wall 22: 2: 2: The piece can be combined into the isolated PET or the polyolefin separator (4). The molded or blown molded plastic container is not exposed to the molding process. Pulling or ejecting the stretch blow 10 1311971 A metal disc 30 is sealed to the underside of the base flange 4 and the removable portion 10. Instead of a solid dish, the removable portion 10 can be constructed as a ring-shaped frame typically having a center, three-point star structure. This frame can be joined to the base flange 4 by a weakened bridge. This will reduce the total weight of the accessory. The metal disc 30 is cut from aluminum metal and coated on both sides, typically a plastic layer of polyethylene, polypropylene or PET, to bond it to other plastic components. The base flange 4 is welded to the carton wall 22 by an induction heat seal or ultrasonic device in the annular region A. A receiving wall 32 surrounds the peripheral edge of the base flange 4 φ. 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. Carton Structure The synthetic cardboard carton 22 is formed from a multilayer 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 Spring 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. 11 1311971 Sealing the edge of the metal The basic feature of the fitting of the present invention is that when the fitting is combined, 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 fused 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 covers the entire lower first surface 54 of the base flange 4 about the edge of the self-turning edge and the second flange 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. Method of manufacture 12 1311971 Prior to the assembly of the accessory to the cardboard carton, the carton accessory 2 is pre-assembled to the metal plate 30 and the metal is welded in place by an induction heat sealing procedure. 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 30 will be welded to the base flange at this time. In the embodiment of the fourth embodiment, the seal established between the edge of the metal 30 and the wall 22 is identical to the other seams elsewhere in this type of cardboard carton. Continuously the barrier layer Once the fitting 2 is welded into the aperture 20 in the cardboard carton wall 22, the barrier layer is replaced by the metal 30 to create a continuous barrier layer having a layer 40 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 10 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 10, 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 10 13 1311971, it is easy to manually punch the metal layer. 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.
