Description

本発明は、内容物が液物であっても消費者が使用するまで嵌合具の開封側に液漏れすることなく、また内容物を取り出す際には接合部分を容易に切り離して袋体を開封することができ、開封後は繰り返し嵌合及び再開封可能な嵌合具及び嵌合具付包装用袋体に関する。   Even if the contents are liquid, the present invention does not leak to the opening side of the fitting until the consumer uses it. The present invention relates to a fitting and a packaging bag with a fitting, which can be opened and can be repeatedly fitted and resumed after opening.

袋の開封部に雄、雌よりなる一対の嵌合具を設けることにより、開閉自在とした嵌合具付包装用袋体が、食品、薬品、雑貨等多くの分野で使用されている。しかしながら内容物の流動性が高い場合、嵌合具の密封性だけで完全に防止することはできなかった。そこで完全に内容物の流出を防止したい場合、嵌合具と原反フィルムとの間に易剥離性フィルムを設けたり、嵌合具又は原反フィルムに易剥離層を設けたりして、嵌合具の非開封側にさらに易剥離性の接合部を設ける、といった対応をしていた。   By providing a pair of fittings made of male and female at the opening portion of the bag, the packaging bag with fittings that can be opened and closed is used in many fields such as food, medicine, and miscellaneous goods. However, when the fluidity of the contents is high, it has not been possible to prevent completely by only the sealing property of the fitting. Therefore, if you want to completely prevent the contents from flowing out, fit easily by providing an easy-release film between the fitting and the original film, or by providing an easy-release layer on the fitting or the original film. The measures such as providing an easily peelable joint on the non-opening side of the tool have been taken.

易剥離性の接合部を設けて内容物の流出を防止する方法が開示されているが（例えば、特許文献１参照。）、易剥離性部分のサイドシール部分は、その他のサイドシール部分よりもシール強度が弱いという欠点がある。
特開平１１−２８５５１８号公報 Although the method of providing the easily peelable joining part and preventing the outflow of the contents is disclosed (for example, refer to Patent Document 1), the side seal part of the easily peelable part is more than the other side seal parts. There is a disadvantage that the sealing strength is weak.
Japanese Patent Laid-Open No. 11-285518

本発明の課題は、内容物が流動性の高い物質であった場合でも、嵌合具の非開封側にさらに易剥離性の接合部を設けるといった対応を必要とすることなく、内容物の流出を防止でき、また袋体を開封して内容物を取り出す際に、容易に接合部分を切り離すことができ、さらに繰り返し密封、開封できる嵌合具及び嵌合具付包装用袋体を提供することである。   The problem of the present invention is that even when the content is a substance having high fluidity, the outflow of the content is not required without further measures such as providing an easily peelable joint on the non-opening side of the fitting. To provide a fitting and a packaging bag with a fitting that can be easily separated and opened repeatedly when the bag is opened and the contents are taken out. It is.

本発明者等は、前記課題を解決するために鋭意検討した結果、雄型側と雌型側との非開封側フランジ部分の先端部が特定の厚さによって接合されており、接合部分とフランジ部分の間に特定の厚さの突起状物を設けることにより、前記課題を解決できることを見出し、本発明を完成するに至った。   As a result of intensive studies to solve the above-mentioned problems, the present inventors have found that the end portions of the unopened flange portions of the male mold side and the female mold side are bonded with a specific thickness, and the bonded portion and the flange It has been found that the above problem can be solved by providing a protrusion having a specific thickness between the portions, and the present invention has been completed.

すなわち本発明は次のとおりである。
（１）雄型と雌型とを有する互いに嵌合可能な嵌合具において、雄型側と雌型側との非開封側フランジ部分の先端部が接合された接合部分を有し、接合部分とフランジ部分の間に突起状物を有し、接合部分の厚さが１０μｍ以上１００μｍ以下であり、かつ突起状物の厚さが２００μｍ以上２ｍｍ以下であり、かつ接合部分の厚さはフランジ部分の厚さより薄く、突起状物の厚さはフランジ部分の厚さより厚いことを特徴とする嵌合具。
（２）袋体に（１）に記載の嵌合具を融着し、製袋してなることを特徴とする嵌合具付包装用袋体。 That is, the present invention is as follows.
(1) In a fitting tool having a male mold and a female mold that can be fitted to each other, the joint includes a joint portion in which the front ends of the unopened flange portions of the male mold side and the female mold side are joined, And the flange portion have a protrusion, the thickness of the joint portion is not less than 10 μm and not more than 100 μm, the thickness of the protrusion is not less than 200 μm and not more than 2 mm, and the thickness of the joint portion is the flange portion The fitting is characterized in that the thickness of the protrusion is thinner than the thickness of the flange portion, and the thickness of the protrusion is thicker than the thickness of the flange portion.
(2) A packaging bag with a fitting, which is formed by fusing the fitting described in (1) to a bag and making a bag.

本発明の嵌合具及び嵌合具付包装用袋体は、内容物が流動性の高い物質であった場合でも、内容物の流出を防止でき、また袋体を開封して内容物を取り出す際に、容易に接合部分を切り離すことができるものである。   The fitting tool and the packaging bag body with the fitting tool of the present invention can prevent the content from flowing out even when the content is a substance having high fluidity, and the bag is opened to take out the content. In this case, the joint portion can be easily separated.

以下、本発明を詳細に説明する。

FIG. 1 schematically shows an example of the fitting of the present invention in a fitted state.
FIG. 2 schematically shows an example of the fitting of the present invention.
FIG. 3 shows a front view of an example of the packaging bag with a fitting of the present invention.

本発明の雄型と雌型とを有する互いに嵌合可能な嵌合具において、雄型側と雌型側との非開封側フランジ部分４の先端部が接合されており、その接合部分２の厚さは１０μｍ以上１００μｍ以下であり、好ましくは２０μｍ以上８０μｍ以下であり、より好ましくは２０μｍ以上５０μｍ以下であり、さらにより好ましくは３０μｍ以上５０μｍ以下である。接合部分２の厚さを上記のように規定したのは、１０μｍ未満では容易に接合部分２を切り離せるが、擦れ等により接合部分２が破損したり、内容物を充填する際に、強度不足により破損したりする為である。また、１００μｍより厚いと接合部分２の強度がありすぎる為、容易に切り離すのは困難になるためである。   In the fitting tool having a male mold and a female mold according to the present invention, which can be fitted to each other, the front end portions of the non-opening flange portions 4 on the male mold side and the female mold side are joined. The thickness is from 10 μm to 100 μm, preferably from 20 μm to 80 μm, more preferably from 20 μm to 50 μm, and even more preferably from 30 μm to 50 μm. The thickness of the joint part 2 is defined as described above. The joint part 2 can be easily separated when the thickness is less than 10 μm, but the joint part 2 is damaged due to rubbing or the like, or the strength is insufficient when filling the contents. This is because of damage. On the other hand, if the thickness is larger than 100 μm, the strength of the joint portion 2 is too high, and it is difficult to easily cut it off.

本発明の嵌合具では、接合部分２とフランジ部分４の間に突起状物３が設けられており、その突起状物３の厚さが２００μｍ以上２ｍｍ以下であり、好ましくは３００μｍ以上１．５ｍｍ以下であり、さらに好ましくは３００μｍ以上１．０ｍｍ以下である。突起状物３を設けたのは、接合部分２に応力集中をさせやすくするためであり、突起状物３がないと、接合部分２とフランジ部分４との境目が曖昧になり接合部分２を容易に切り離すことができなくなるためである。突起状物３の厚さが２００μｍ未満では、接合部分２と突起状物３との厚み差が少なく接合部分２に応力集中しにくくなる。また、２ｍｍより厚いと突起状物３における樹脂量が多くなり過ぎてしまい、製袋でサイドシールする際に潰しきれずに製袋不良となりやすい。また、雄型、雌型を嵌合させる際に、嵌合を阻害したり、接合部分３を破損させてしまいやすい。   In the fitting device of the present invention, the protrusion 3 is provided between the joint portion 2 and the flange portion 4, and the thickness of the protrusion 3 is 200 μm or more and 2 mm or less, preferably 300 μm or more and 1. It is 5 mm or less, More preferably, it is 300 micrometers or more and 1.0 mm or less. The reason why the protrusion 3 is provided is to make it easy to concentrate stress on the joint portion 2. Without the protrusion 3, the boundary between the joint portion 2 and the flange portion 4 becomes ambiguous, and the joint portion 2 is formed. This is because it cannot be easily separated. If the thickness of the protrusion 3 is less than 200 μm, the thickness difference between the joint portion 2 and the protrusion 3 is small, and it is difficult for stress to concentrate on the joint portion 2. On the other hand, if it is thicker than 2 mm, the amount of resin in the protrusions 3 is excessively increased, and when the side sealing is performed in the bag making, the bag is not completely crushed and the bag making is likely to be defective. Further, when the male mold and the female mold are fitted, the fitting is hindered or the joint portion 3 is easily damaged.

本発明の嵌合具を構成する樹脂に制限はないが、ポリエチレン、ポリプロピレン等のポリオレフィン系樹脂が好適に用いられ、また２種以上からなる樹脂組成物であってもよい。また、雄型、雌型の形状、本数については特に制限されず、再開閉機能を有するものであれば任意の形状とすることができる。   Although there is no restriction | limiting in resin which comprises the fitting tool of this invention, Polyolefin-type resins, such as polyethylene and a polypropylene, are used suitably, Moreover, the resin composition which consists of 2 or more types may be sufficient. Further, the shape and number of the male and female dies are not particularly limited, and any shape can be used as long as it has a reopening / closing function.

本発明の嵌合具を得る方法としては特に制限はなく、押出機により溶融混練した樹脂を金型から押出し、冷却して成形する等の公知の方法を用いることができる。   There is no restriction | limiting in particular as a method of obtaining the fitting tool of this invention, Well-known methods, such as extruding resin melt-kneaded with the extruder from a metal mold | die, cooling, can be used.

また、本発明の嵌合具を袋本体たる基材フィルムに熱融着する方法により嵌合具付包装用袋体を得ることができる。   Moreover, the packaging bag body with a fitting tool can be obtained by the method of heat-seal | fusing the fitting tool of this invention to the base film which is a bag main body.

また、本発明の嵌合具及び嵌合具付包装用袋体は、乾燥物、固形物の他、カレー、おかゆ、たれや餡等の調味料等のような内容物が流動物及び液物の包装等にも好適に用いることができる。   In addition, the fitting and the packaging bag with the fitting according to the present invention are fluids and liquids, such as seasonings such as curry, porridge, sauce and rice cake, in addition to dried products and solids. It can be suitably used for packaging and the like.

以下、実施例に基づき本発明の内容をより具体的に説明するが、本発明は以下の実施例に記載された事項によってのみ限定されるものではない。   Hereinafter, the content of the present invention will be described more specifically based on examples, but the present invention is not limited only to the matters described in the following examples.
