Japanese Patent Publication No. 3-76818

しかしながら、従来の製造方法においては、以下に示す欠点があった。
（１）図１０に示すように、内ショルダー５１の下端部内側近傍に接触するチューブ容器内の内容物が、外気によって変色、変質するという欠点があった。これは、図１２に示すように、チューブショルダー５０と閉鎖膜５２の隙間から、外気が閉鎖膜５２の皺５９の凹凸を伝って内部に進入するためである（矢印Ｘ）。又逆に、内容物が閉鎖膜５２の皺５９の凹凸を伝って、閉鎖膜５２のバリア層に浸透するため、閉鎖膜５２のバリア層がアルミニウム箔の場合、腐食するという欠点があった（矢印Ｙ）。
（２）さらに、図１３に示すように、胴部５４のバリア層５４ｄと、閉鎖膜５２のバリア層５２ｄの最短距離Ｌが、１．０〜５ｍｍと大きいため、チューブショルダー５０を透過した外気が、この隙間Ｌからチューブ内に流入して、内容物を変質させるという欠点があった（矢印Ｚ）。
本発明は、このような問題に着目してなされたものであり、外気の透過及び内容物の浸透を防止した、内容物の保存性に優れた閉鎖膜チューブ容器の製造方法を提供することを目的とするものである。 However, the conventional manufacturing method has the following drawbacks.
(1) As shown in FIG. 10, there is a drawback that the contents in the tube container that contacts the vicinity of the inner side of the lower end of the inner shoulder 51 are discolored and deteriorated by the outside air. This is because, as shown in FIG. 12, outside air enters the inside through the gap between the tube shoulder 50 and the closing membrane 52 through the unevenness of the flange 59 of the closing membrane 52 (arrow X). On the other hand, since the contents penetrate the unevenness of the ridge 59 of the closing film 52 and penetrate into the barrier layer of the closing film 52, there is a drawback that the barrier layer of the closing film 52 is corroded (corresponding to the corrosion) Arrow Y).
(2) Furthermore, as shown in FIG. 13, since the shortest distance L between the barrier layer 54d of the body portion 54 and the barrier layer 52d of the closing membrane 52 is as large as 1.0 to 5 mm, the outside air that has passed through the tube shoulder 50 However, there was a defect that the contents flow into the tube from the gap L to alter the contents (arrow Z).
The present invention has been made paying attention to such problems, and provides a method for producing a closed membrane tube container excellent in storage stability of contents, which prevents permeation of outside air and penetration of contents. It is the purpose.

この課題を解決するため、請求項１記載の発明の解決手段は、内ショルダーの上面に閉鎖膜を被着した円盤部材を、マンドレルヘッド上に載置し、次いでショルダー材を、前記円盤部材上に落下し、該ショルダー材を上金型で押圧してチューブショルダを成形し、前記閉鎖膜を内ショルダーとチューブショルダーで挟着したことを特徴とする閉鎖膜チューブ容器の製造方法である。環状のショルダー材を上金型で、強く押圧してチューブショルダーを成形するので、溶融した樹脂が金型の押圧力で、閉鎖膜の外周の皺の凹凸内に入り込む。そして、皺の凹凸の周囲を樹脂で埋めることができるので、皺を伝って外気がチューブ容器内に流入するのを防止することができる。又内容物が皺を伝って、バリア層に入り込むのを防止することができる。   In order to solve this problem, the solving means of the invention described in claim 1 is that a disk member having a closure film attached to the upper surface of an inner shoulder is placed on a mandrel head, and then a shoulder material is placed on the disk member. The closed membrane tube container is formed by pressing the shoulder material with an upper mold to form a tube shoulder, and sandwiching the closed membrane between the inner shoulder and the tube shoulder. Since the tube shoulder is formed by strongly pressing the annular shoulder material with the upper mold, the molten resin enters the irregularities of the ridges on the outer periphery of the closing film by the pressing force of the mold. And since the circumference | surroundings of the unevenness | corrugation of a soot can be filled with resin, it can prevent that external air flows in into a tube container along a soot. Further, it is possible to prevent the contents from entering the barrier layer through the soot.

請求項２記載の発明の解決手段は、マンドレルヘッドの外周面に、積層シートが円筒状に丸めて支持される胴部が、チューブショルダーの下端に溶着される閉鎖膜チューブ容器の製造方法であって、前記胴部のバリア層と、前記閉鎖膜のバリア層の最短距離Ｓが、０＜Ｓ≦１．０ｍｍであることを特徴とする閉鎖膜チューブ容器の製造方法である。   According to a second aspect of the present invention, there is provided a closed membrane tube container manufacturing method in which a body portion on which a laminated sheet is rolled up and supported on an outer peripheral surface of a mandrel head is welded to a lower end of a tube shoulder. The shortest distance S between the barrier layer of the trunk portion and the barrier layer of the closing membrane is 0 <S ≦ 1.0 mm.

請求項３記載の発明の解決手段は、バリア層が、アルミニウム箔又はガスバリア性樹脂で構成されることを特徴とする閉鎖膜チューブ容器の製造方法である。   According to a third aspect of the present invention, there is provided a closed membrane tube container manufacturing method, wherein the barrier layer is made of an aluminum foil or a gas barrier resin.

請求項４記載の発明の解決手段は、胴部の表面に継ぎ目を有することを特徴とする閉鎖膜チューブ容器の製造方法である。   According to a fourth aspect of the present invention, there is provided a closed membrane tube container manufacturing method comprising a seam on the surface of the body portion.

請求項５記載の発明にお解決手段は、胴部の表面に継ぎ目がないことを特徴とする閉鎖膜チューブ容器の製造方法である。   According to a fifth aspect of the present invention, there is provided a method for producing a closed membrane tube container characterized in that the surface of the body portion is seamless.

この発明によれば、内容物内への外気の透過及び内容物の閉鎖膜への浸透を防止することができ、内容物の保存性に優れた効果を有する。   According to the present invention, it is possible to prevent the permeation of the outside air into the contents and the penetration of the contents into the closing membrane, and it has an excellent effect on the storage stability of the contents.

以下、本発明の実施例の一例を図面に基づいて説明する。   Hereinafter, an example of an embodiment of the present invention will be described with reference to the drawings.

図１〜図４は、本発明の実施例１を示す図面である。図１は、内ショルダー１の上面に閉鎖膜２を被着した円盤部材３を、マンドレルヘッド４上に載置した製造工程を示したものである。筒部１ａと肩部１ｂから構成された内ショルダー１は、例えばポリエチレン樹脂、ポリプロピレン樹脂等で予め成形される。又蓋部２ａ、筒状の側壁部２ｂ及び傘状の裾部２ｃから構成された閉鎖膜２は、予め円盤状に切断したアルミニウムの板材を絞り成形して製造される。閉鎖膜２はアルミニウム箔の他、ガスバリア性の樹脂材料等から構成されている。バリア層２ｄがアルミニウム箔の場合、少なくともその表面又は裏面にポリエチレン等の樹脂が積層されており、内ショルダー１及びチューブショルダー５ａとの溶着が強固になる。閉鎖膜２は溶着する下面が１５０〜２５０℃に加熱され、内ショルダー１上に溶着される。図２は、この閉鎖膜２と内ショルダー１から構成される円盤部材３を、マンドレルヘッド４上に載置し、上方から２００〜３００℃に溶融したショルダー材５を、円盤部材３の閉鎖膜２上に落下する状態を示す図面である。ショルダー材５は、実施例１では環状を呈しているが、形状は任意に選択することができる。又ショルダー材５は、例えばポリエチレン樹脂、ポリプロピレン樹脂、ポリエチレンテレフタレート樹脂、エチレン−ビニルアルコール共重合体樹脂等で構成されている。なお、マンドレルヘッド４の外周には、内部にアルミニウム箔等のバリア層６ａを有する胴部６が、丸めて巻き付けられている。   1 to 4 show a first embodiment of the present invention. FIG. 1 shows a manufacturing process in which a disk member 3 having a closure film 2 attached to the upper surface of an inner shoulder 1 is placed on a mandrel head 4. The inner shoulder 1 composed of the cylindrical portion 1a and the shoulder portion 1b is molded in advance with, for example, polyethylene resin, polypropylene resin or the like. The closure film 2 composed of the lid portion 2a, the cylindrical side wall portion 2b, and the umbrella-like skirt portion 2c is manufactured by drawing an aluminum plate material that has been cut into a disk shape in advance. The closing film 2 is made of an aluminum foil, a gas barrier resin material, or the like. In the case where the barrier layer 2d is an aluminum foil, a resin such as polyethylene is laminated on at least the front surface or the back surface thereof, and the welding with the inner shoulder 1 and the tube shoulder 5a becomes strong. The lower surface to be welded of the closing film 2 is heated to 150 to 250 ° C. and is welded onto the inner shoulder 1. FIG. 2 shows that the disc member 3 composed of the closure membrane 2 and the inner shoulder 1 is placed on the mandrel head 4 and the shoulder member 5 melted at 200 to 300 ° C. from above is used as the closure membrane of the disc member 3. It is drawing which shows the state which falls on 2. FIG. The shoulder material 5 has an annular shape in the first embodiment, but the shape can be arbitrarily selected. The shoulder material 5 is made of, for example, polyethylene resin, polypropylene resin, polyethylene terephthalate resin, ethylene-vinyl alcohol copolymer resin, or the like. A body 6 having a barrier layer 6a such as an aluminum foil is rolled and wound around the outer periphery of the mandrel head 4.

図３は、閉鎖膜２を上面に溶着した円盤部材３上に、溶融した環状のショルダー材５を落下し、その上からマトリクス及びフォーミングから成る金型７で押圧成形し、チューブショルダー５ａを成形するものである。上金型７による強い押圧力で、チューブショルダー５ａを成形した場合、図５（図４のＷ−Ｗ線拡大断面図）に示すように、閉鎖膜２の皺２ｅの周囲に溶融樹脂が入り込み、皺２ｅを完全に埋め込むことができる。すなわち、発明者は、溶融した環状のショルダー材５を、上金型７で強く押圧成形することで、溶融樹脂で皺２ｅの凹凸の周囲を完全に埋めることができることを見出したのである。図５に示すように、チューブショルダー５ａと閉鎖膜２の隙間がなくなり、皺を伝って外気が内部に流入するのを阻止することができる。従来の公知の製造方法である、予め成形したチューブショルダーの内側に、円盤部材を単に溶着した場合や、円盤部材の上に単に射出成形により溶融樹脂を流し込んで、チューブショルダーを一体成形する場合においては、溶融樹脂により皺の凹凸を完全に埋めることが不可能であり、チューブショルダー５ａと閉鎖膜２の間に隙間が生じていた。   FIG. 3 shows that a molten annular shoulder member 5 is dropped on a disk member 3 having a closure film 2 welded to the upper surface, and is pressed by a die 7 comprising a matrix and forming from above to form a tube shoulder 5a. To do. When the tube shoulder 5a is formed with a strong pressing force by the upper mold 7, the molten resin enters the periphery of the flange 2e of the closing film 2 as shown in FIG. , 2e can be completely embedded. That is, the inventor has found that the periphery of the unevenness of the heel 2e can be completely filled with the molten resin by strongly pressing the molten annular shoulder material 5 with the upper mold 7. As shown in FIG. 5, there is no gap between the tube shoulder 5a and the closing membrane 2, and it is possible to prevent outside air from flowing into the interior through the ridge. In the conventional well-known manufacturing method, when a disk member is simply welded to the inside of a pre-formed tube shoulder, or when a molten resin is simply poured onto the disk member by injection molding to integrally mold the tube shoulder However, it was impossible to completely fill the unevenness of the ridges with the molten resin, and a gap was generated between the tube shoulder 5a and the closing membrane 2.

次ぎに、本発明の実施例２は、図６に示すように、チューブショルダー５ａを成形すると同時に、上金型７による押圧成形により胴部６が、チューブショルダー５ａの下端に溶着される。本発明は、胴部６のアルミニウム箔等のバリア層６ａと、閉鎖膜２のアルミニウム箔等のバリア層２ｄの最短距離Ｓが、０＜Ｓ≦１．０ｍｍになるように構成されている。実施例２においては、チューブショルダー５ａの肉厚を薄く形成することが重要である。なお、閉鎖膜２は、バリア層２ｄがアルミニウム箔である場合は、少なくとも片面に、ポリエチレンテレフタレート樹脂、その外側にポリエチレン樹脂を積層することにより、閉鎖膜２の開口を容易にすると共に、内ショルダー１及びチューブショルダー５ａとの溶着を強固なものとすることができる。   Next, in Example 2 of the present invention, as shown in FIG. 6, the tube shoulder 5 a is molded, and at the same time, the body 6 is welded to the lower end of the tube shoulder 5 a by press molding with the upper mold 7. In the present invention, the shortest distance S between the barrier layer 6a such as an aluminum foil of the trunk portion 6 and the barrier layer 2d such as an aluminum foil of the closing film 2 is configured to satisfy 0 <S ≦ 1.0 mm. In the second embodiment, it is important to make the tube shoulder 5a thin. When the barrier layer 2d is an aluminum foil, the closing membrane 2 is formed by laminating a polyethylene terephthalate resin on at least one side and a polyethylene resin on the outside thereof, thereby facilitating the opening of the closing membrane 2 and the inner shoulder. 1 and the tube shoulder 5a can be firmly welded.

実施例２は、このようにバリア層間の最短距離Ｓを１ｍｍ以下に小さくしたことにより、外気がチューブショルダー５ａを透過して、内容物内に混入するのを防止することができる。なお、閉鎖膜２のバリア層２ｄは、アルミニウム箔の他、エチレン−ビニルアルコール共重合体、ナイロン樹脂、ポリエチレンテレフタレート樹脂、ポリアクリルニトリル樹脂等のガスバリア性樹脂で構成されてもよい。又同様に、胴部６のバリア層６ａも、アルミニウム箔の他、エチレン−ビニルアルコール共重合体、ナイロン樹脂、ポリエチレンテレフタレート樹脂、ポリアクリルニトリル樹脂等のガスバリア性樹脂であってもよい。   In Example 2, the shortest distance S between the barrier layers is reduced to 1 mm or less as described above, so that outside air can be prevented from passing through the tube shoulder 5a and entering the contents. In addition, the barrier layer 2d of the closing film 2 may be made of a gas barrier resin such as an ethylene-vinyl alcohol copolymer, a nylon resin, a polyethylene terephthalate resin, or a polyacrylonitrile resin in addition to the aluminum foil. Similarly, the barrier layer 6a of the body portion 6 may be a gas barrier resin such as an ethylene-vinyl alcohol copolymer, a nylon resin, a polyethylene terephthalate resin, or a polyacrylonitrile resin in addition to the aluminum foil.

図７はこの発明の実施例３であり、閉鎖膜１２の傘状の裾部１２ｃが、若干上方に持ち上げられた状態で、ほぼ水平方向の位置に成形された実施例である。その他の構成は、実施例１と同様である。   FIG. 7 shows a third embodiment of the present invention, in which the umbrella-like skirt portion 12c of the closing membrane 12 is formed at a substantially horizontal position while being lifted slightly upward. Other configurations are the same as those of the first embodiment.

上記製造方法で製造されたチューブ容器は、図８に示すように、積層シートが円筒状に丸められ、相互の端部を上下に重ね又は突き合わされて溶着されている。すなわち、本発明は、継ぎ目がある胴部２６を有する一般的な閉鎖膜チューブ容器に適用することができる。又他の実施例として、本発明は、図９に示すように、継ぎ目がない胴部３６を有する閉鎖膜チューブ容器にも適用することができる。胴部３６は、外観上継ぎ目がないので、
外観的に美麗であると共に印刷面を特定する必要がない利点がある。この継ぎ目がない胴部３６を有する閉鎖膜チューブ容器は、従来公知の製造方法で製造される。 As shown in FIG. 8, the tube container manufactured by the above manufacturing method is formed by laminating a laminated sheet into a cylindrical shape, and welding each other by overlapping or butting each other up and down. That is, the present invention can be applied to a general closed membrane tube container having a body portion 26 with a seam. As another embodiment, the present invention can be applied to a closed membrane tube container having a seamless body 36 as shown in FIG. Since the body portion 36 is seamless in appearance,
There are advantages that it is beautiful in appearance and does not need to specify the printing surface. The closed membrane tube container having the seamless body portion 36 is manufactured by a conventionally known manufacturing method.

本発明に係る製造方法は、外部からの酸素等のガスの透過を完全に防止でき、又閉鎖膜の腐食を防止することができるので、流通、販売過程における内容物の劣化を防止することができる。又開封後においても、ねじ部、口部のガス遮断効果を有するので、閉鎖膜チューブ容器として、医薬品、食品、歯磨き等を収納するのに広く適し、多岐分野にわたって利用することができる。   The manufacturing method according to the present invention can completely prevent the permeation of gas such as oxygen from the outside, and can prevent the corrosion of the closure membrane, so that it can prevent the deterioration of the contents in the distribution and sales process. it can. Further, even after opening, since it has a gas barrier effect at the screw part and the mouth part, it can be widely used as a closed membrane tube container for storing pharmaceuticals, foods, toothpaste, etc., and can be used in various fields.
