Description

本発明は、液体を含浸しているシート材が収容されているフィルム製の袋体に取り付けられる樹脂蓋に関する。 The present invention relates to a resin lid attached to a film bag containing a sheet material impregnated with liquid.

メイク落とし、クレンジング、ローション等の液体化粧料や消毒液等の液体を含浸させた不織布、ティッシュペーパー等のシート材の積層体を備えたフィルム製の袋体に収容したシート材製品であって、シート取出口に蓋として再剥離性の封緘ラベルを設けたものが使用されている。 A sheet material product housed in a film bag comprising a laminate of sheet materials such as nonwoven fabric and tissue paper impregnated with liquid cosmetics such as makeup removers, cleansers, and lotions, and liquids such as disinfectants, A removable sealing label is used as a lid over the sheet outlet.

このようなシート材製品において、シート材の取り出しを容易にすると共に、シート材の密封性を向上させるため、シート材を収容したフィルム製の袋体に樹脂蓋が固着されているものがある。しかしながら、袋体に固着されている樹脂蓋は使い捨てとなり、袋体に対して樹脂量の多い樹脂蓋を使い捨てとすることは環境適応性の観点から好ましくない。 In some of these sheet material products, a resin lid is fixed to a film bag containing the sheet material in order to facilitate the removal of the sheet material and improve the sealing properties of the sheet material. However, the resin lid fixed to the bag body is disposable, and it is not preferable from the viewpoint of environmental adaptability to make the resin lid with a large amount of resin relative to the bag body disposable.

そこで、樹脂蓋の再利用を図るため、シート材を収容した袋体に対して付け替え可能に取り付けられるようにした樹脂蓋が提案されている（特許文献１）。この樹脂蓋は、袋体のシート取出口上に配置される開口部と、該開口部を形成する枠部と、枠部の裏面側に突出して袋体内部に挿入される挿入部と、挿入部の先端に形成されたフランジ部とを有し、枠部の裏面が袋体の天面に貼着される。この樹脂蓋では挿入部が袋体内部に挿入されることにより樹脂蓋と袋体との間に隙間ができることを防止してシート材の乾燥を防止し、また、袋体のシート取出口の縁部を、樹脂蓋の枠部とフランジ部とで挟むことにより樹脂蓋が袋体から不用意に外れることを防止する。 Therefore, in order to reuse the resin lid, a resin lid has been proposed that can be reattached to a bag containing a sheet material (Patent Document 1). This resin lid includes an opening disposed above the sheet outlet of the bag, a frame forming the opening, an insertion part that protrudes from the back side of the frame and is inserted into the bag, and an insertion part that protrudes from the back side of the frame and is inserted into the bag. The bag has a flange portion formed at the tip of the frame portion, and the back surface of the frame portion is attached to the top surface of the bag body. With this resin lid, the insertion part is inserted into the bag body to prevent a gap from forming between the resin lid and the bag body, preventing the sheet material from drying out, and also to prevent the sheet material from drying out. By sandwiching the portion between the frame portion and the flange portion of the resin lid, the resin lid is prevented from being accidentally removed from the bag body.

特開2014-31193号公報Japanese Patent Application Publication No. 2014-31193

シート材の重量に対する、該シート材に含浸した液体の重量の割合を含浸率とした場合に、含浸率４００％超という高含浸シートのシート材を収容した袋体に特許文献１に記載の樹脂蓋を取り付けると、挿入部が樹脂蓋と袋体との貼着面よりも袋体内部に挿入されるので、樹脂蓋の袋体への取り付け時にシート材が挿入部で押圧されて液体がしみ出し、その液体が樹脂蓋と袋体との貼着力を低下させる虞がある。 When the ratio of the weight of the liquid impregnated into the sheet material to the weight of the sheet material is defined as the impregnation rate, the resin described in Patent Document 1 is used in a bag containing a sheet material with a high impregnation rate of over 400%. When the lid is attached, the insertion part is inserted into the bag body beyond the adhesive surface between the resin lid and the bag body, so when the resin lid is attached to the bag body, the sheet material is pressed by the insertion part and liquid stains. There is a risk that the liquid may reduce the adhesion between the resin lid and the bag body.

また、袋体のシート取出口の縁部を樹脂蓋と枠部とフランジ部とで挟まなくてはならないため、樹脂蓋の袋体への取り付け作業が煩雑となる。さらに、特許文献１には、挿入部が袋体内部へ突出する長さを例えば３ｍｍ～３０ｍｍにするとあり、そのように挿入部を袋体内部に突出させると、枠部を袋体に押し付けても枠部の裏面を袋体の天面に強く押圧することが難しく、これらに十分な貼着力をもたせることが難しくなる。 Furthermore, since the edge of the sheet outlet of the bag must be sandwiched between the resin lid, the frame, and the flange, the work of attaching the resin lid to the bag becomes complicated. Furthermore, Patent Document 1 states that the length of the insertion portion protruding into the inside of the bag is, for example, 3 mm to 30 mm, and when the insertion portion is made to protrude into the inside of the bag in this way, the frame portion is pressed against the bag. However, it is difficult to strongly press the back surface of the frame against the top surface of the bag, and it is difficult to provide sufficient adhesion force thereto.

加えて、樹脂蓋の開口部の周りは、枠部と挿入部とフランジ部で断面がコの字状となるためこの部分に液体が付着したままになり易く、樹脂蓋の付け替え時にこの部分を洗い流すことが容易でない。そのため、樹脂蓋を新たな袋体に付け替えても、コの字状部分には付け替え前の袋体の液体が付着したままになり、衛生的に好ましくない。 In addition, the area around the opening of the resin lid has a U-shaped cross section with the frame, insertion portion, and flange, so liquid tends to remain attached to this area, so be sure to remove this area when replacing the resin lid. Not easy to wash off. Therefore, even if the resin lid is replaced with a new bag, the liquid from the bag before replacement remains attached to the U-shaped portion, which is not sanitary.

これに対し、本発明の課題は、液体を含浸したシート材が収容されたフィルム製の袋体に付け替え可能に取り付けられる樹脂蓋において、袋体への取り付けを容易にし、取り付け時にシート材からの液体のしみ出しを起こりにくくして樹脂蓋と袋体との接着力が液体によって低下することを防止し、付け替え時の洗浄が容易な構造とすることに関する。 In contrast, an object of the present invention is to provide a resin lid that can be attached removably to a film bag containing a liquid-impregnated sheet material, to facilitate attachment to the bag, and to prevent the sheet material from being removed during installation. The present invention relates to a structure that prevents liquid from seeping out, prevents the adhesive force between a resin lid and a bag body from decreasing due to liquid, and facilitates cleaning when replacing.

本発明者は、樹脂蓋の裏面がシート取出用の開口部の周りに環状リブを有し、環状リブの基面を、樹脂蓋と袋体との貼着面よりも天面部の表面方向に位置させると、樹脂蓋を袋体に取り付けるときの環状リブによる袋体内のシート材の押圧量が低減して、シート材から液体がしみ出にくくなり、また、樹脂蓋の裏面の環状リブと貼着部との間に裏面凹部を設けることができ、裏面凹部がシート材からしみ出た液体の液溜めとして機能することを想到し、本発明を完成させた。 The inventor has proposed that the back surface of the resin lid has an annular rib around the opening for taking out the sheet, and that the base surface of the annular rib is directed toward the surface of the top surface part from the adhesive surface of the resin lid and the bag body. By positioning the lid in this position, the amount of pressure the annular rib presses against the sheet material inside the bag when attaching the resin lid to the bag body is reduced, making it difficult for liquid to seep out from the sheet material. The present invention was completed based on the idea that a recessed portion on the back side can be provided between the sheet material and the recessed portion, and that the recessed portion on the back side functions as a reservoir for liquid seeped from the sheet material.

即ち、本発明は、液体を含浸したシート材が収容されたフィルム製の袋体のシート取出口に付け替え可能に取り付けられる樹脂蓋であって、シート取出用の開口部を有する天面部、天面部に支持されて前記開口部を開閉する蓋板、天面部の周囲にあって袋体の外表面と貼着する貼着部を有し、
天面部の裏面は、前記開口部を囲む環状リブと、環状リブと貼着部との間にある裏面凹部を有し、天面部の裏面において環状リブが突出する基面が、貼着部と袋体との貼着面に対して天面部の表面方向に位置する樹脂蓋を提供する。 That is, the present invention provides a resin lid that is removably attached to a sheet outlet of a film bag containing a liquid-impregnated sheet material, and includes a top surface portion having an opening for sheet extraction; a lid plate that is supported by and opens and closes the opening; an adhesive part that is located around the top part and that adheres to the outer surface of the bag;
The back surface of the top surface part has an annular rib surrounding the opening and a back recess between the annular rib and the adhesive part, and the base surface from which the annular rib protrudes on the back surface of the top part is connected to the adhesive part. To provide a resin lid located in the surface direction of a top surface part with respect to a surface to which it is attached to a bag body.

また、本発明は、上述の樹脂蓋の貼着部が、液体を含浸したシート材が収容されたフィルム製の袋体の外表面のシート取出口の外周部に貼着されている包装体を提供する。 Further, the present invention provides a package in which the adhesive part of the resin lid described above is adhered to the outer periphery of the sheet outlet on the outer surface of the film bag containing the liquid-impregnated sheet material. provide.

本発明の樹脂蓋によれば、シート取出用の開口部を有する天面部の裏面に、該開口部を囲む環状リブが形成され、環状リブと貼着部との間が裏面凹部となっているので、シートが押されるなどしてシートから液体がしみ出ても裏面凹部で液体が保持される。これにより、シート材からしみ出た液体が樹脂蓋の貼着部と袋体との貼着面に浸入して貼着部と袋体との貼着力を低下させることを防止でき、またしみ出た液体が樹脂蓋の外に漏れ出ることも防止できる。 According to the resin lid of the present invention, an annular rib surrounding the opening is formed on the back surface of the top section having the opening for taking out the sheet, and a recess on the back surface is formed between the annular rib and the sticking section. Therefore, even if liquid seeps out of the sheet due to the sheet being pushed, the liquid will be retained in the recessed portion on the back side. This prevents liquid seeping from the sheet material from entering the adhesive surface between the adhesive part of the resin lid and the bag body and reducing the adhesion force between the adhesive part and the bag body. It is also possible to prevent liquid from leaking out of the resin lid.

また、環状リブの基面が、樹脂蓋の貼着部と袋体との貼着面よりも天面部の表面方向に位置しているので、その分、環状リブの先端部が樹脂蓋の天面寄りに位置する。したがって、液体を含浸したシート材が収容されたフィルム製の袋体に樹脂蓋を押圧して取り付ける際に、環状リブに押圧力が集中することなく樹脂蓋の貼着部を袋体の天面に十分に押圧することが可能となる。よって、樹脂蓋を袋体に取り付ける際にシート材から液体がしみ出ることを抑制することができ、これによってもしみ出た液体により樹脂蓋の貼着部と袋体との貼着力が低下したり、しみ出た液体が樹脂蓋の外に漏れ出たりすることを防止できる。 In addition, since the base surface of the annular rib is located closer to the surface of the top surface than the adhesion surface between the adhesive part of the resin lid and the bag body, the tip of the annular rib is positioned closer to the top surface of the resin lid. Located close to the front. Therefore, when attaching a resin lid by pressing it to a film bag containing a liquid-impregnated sheet material, the adhesive part of the resin lid can be attached to the top surface of the bag without the pressing force being concentrated on the annular rib. This makes it possible to apply sufficient pressure. Therefore, it is possible to suppress liquid from seeping out from the sheet material when attaching the resin lid to the bag body, and as a result, the adhesive force between the adhesive part of the resin lid and the bag body is reduced due to the liquid that seeps out. This prevents the seeped liquid from leaking out of the resin lid.

このように本発明の樹脂蓋によれば、シート材からしみ出た液体によって貼着部と袋体との貼着力が低下することが防止できるので、樹脂蓋が袋体から不用意に外れないようにするために、特許文献１に記載の、袋体のシート取出口の縁部を挟むコの字状の構造を樹脂蓋に設けることは不要となり、樹脂蓋の付け替え時等において、必要に応じて樹脂蓋を洗い流すことが容易となる。よって、清潔な衛生状態を維持することが可能となる。 As described above, according to the resin lid of the present invention, it is possible to prevent the adhesion force between the adhesive part and the bag body from decreasing due to liquid seeping from the sheet material, so that the resin lid will not be accidentally removed from the bag body. In order to do this, it is no longer necessary to provide the resin lid with the U-shaped structure that sandwiches the edge of the sheet outlet of the bag body, as described in Patent Document 1, and when replacing the resin lid, etc., it is no longer necessary. Accordingly, the resin lid can be easily washed away. Therefore, it becomes possible to maintain clean and sanitary conditions.

FIG.

（袋体）
本実施例の袋体１０は、液体を含浸している複数枚のシート材を積層状態で収容したもので、フィルムで形成されている。袋体１０を構成するフィルムとしては、軟質のポリエチレン、ポリプロピレン、ポリエステル、ポリアミド等の樹脂フィルム、又は樹脂フィルム、紙、アルミ箔が任意の組合せで積層された複合フィルム等を挙げることができる。樹脂フィルムは、一種の樹脂で形成された単体フィルムでもよく複数種の樹脂層で形成された積層フィルムでもよい。また、包装体を形成するフィルムは片面がヒートシール可能であることが好ましい。 (Bag body)
The bag 10 of this embodiment contains a plurality of sheets impregnated with liquid in a stacked state, and is made of film. Examples of the film constituting the bag 10 include soft resin films such as polyethylene, polypropylene, polyester, and polyamide, or composite films in which resin films, paper, and aluminum foil are laminated in any combination. The resin film may be a single film made of one kind of resin, or a laminated film made of plural kinds of resin layers. Further, it is preferable that one side of the film forming the package is heat-sealable.

シート材２としては、不織布、ガーゼ等の織布、ティッシュペーパー等を挙げることができ、シート材に含浸させる液体としては、メイク落とし、クレンジング、ローション等を挙げることができる。シート材の重量に対する液体の重量の割合を含浸率とした場合に、含浸率が好ましくは３００％以上、より好ましくは４００％以上の高含浸率で液体がシート材からしみ出しやすい場合に本発明の意義が高い。含浸率の上限としては７００％程度とすることができる。 Examples of the sheet material 2 include nonwoven fabrics, woven fabrics such as gauze, tissue paper, etc., and examples of the liquid to be impregnated into the sheet material include makeup remover, cleansing, lotion, and the like. When the impregnation rate is defined as the ratio of the weight of the liquid to the weight of the sheet material, the present invention applies when the liquid easily seeps out from the sheet material at a high impregnation rate, preferably 300% or more, more preferably 400% or more. is highly significant. The upper limit of the impregnation rate can be about 700%.

袋体１０はその天面１１にシート取出口１２を有し、樹脂蓋２０を取り付ける前のシート取出口１２は封緘ラベル１３で封じられている。封緘ラベル１３は、再剥離性粘着層により着脱自在にシート取出口１２を覆うものであって良い。一方、本発明においては樹脂蓋２０の開閉によってシート材２を取り出すため、封緘ラベル１３は必ずしも再剥離性粘着層により貼着する必要は無く、剥離性粘着層でも良い。 The bag body 10 has a sheet outlet 12 on its top surface 11, and the sheet outlet 12 is sealed with a sealing label 13 before the resin lid 20 is attached. The sealing label 13 may cover the sheet outlet 12 in a removable manner using a removable adhesive layer. On the other hand, in the present invention, since the sheet material 2 is taken out by opening and closing the resin lid 20, the sealing label 13 does not necessarily need to be attached using a removable adhesive layer, and may be a removable adhesive layer.

封緘ラベル１３を除去した袋体１０のシート取出口１２には、樹脂蓋２０が付け替え可能に取り付けられる。 A resin lid 20 is removably attached to the sheet outlet 12 of the bag 10 from which the sealing label 13 has been removed.

（樹脂蓋）
樹脂蓋２０は、その中央部にある天面部２１にシート取出用の開口部２２を有する。本実施例においてこの開口部２２の外形は、袋体１０のシート取出口１２の外形よりも大きく、封緘ラベル１３の外形よりも小さい。そこで、図３に示したように、封緘ラベル１３を除去した状態で、樹脂蓋２０が袋体１０のシート取出口１２に取り付けられる。一方、本発明においては樹脂蓋２０の開口部２２の外形を、袋体１０の封緘ラベル１３の外形より大きくしてもよい。その場合には、封緘ラベル１３を閉じた状態のままで樹脂蓋２０を袋体１０に取り付け、シートの取り出しの度に蓋板２３と封緘ラベル１３をそれぞれ開閉するようにしてもよい。これにより、包装体１におけるシート材２の密封状態を向上させることができる。 (resin lid)
The resin lid 20 has an opening 22 for taking out the sheet in a top surface 21 located in the center thereof. In this embodiment, the outer shape of the opening 22 is larger than the outer shape of the sheet outlet 12 of the bag 10 and smaller than the outer shape of the sealing label 13. Therefore, as shown in FIG. 3, the resin lid 20 is attached to the sheet outlet 12 of the bag body 10 with the sealing label 13 removed. On the other hand, in the present invention, the outer shape of the opening 22 of the resin lid 20 may be larger than the outer shape of the sealing label 13 of the bag body 10. In that case, the resin lid 20 may be attached to the bag body 10 while the sealing label 13 remains closed, and the lid plate 23 and the sealing label 13 may be opened and closed each time a sheet is taken out. Thereby, the sealed state of the sheet material 2 in the package 1 can be improved.

天面部２１は、開口部２２を開閉する蓋板２３を支持している。蓋板２３の支持態様は特に限定されない。例えば、天面部２１と蓋板２３とがヒンジ２４で折れ曲がるようにこれらを一体に成形してもよく、天面部２１と別個に成形した蓋板２３の一端を天面部２１に嵌合させてもよい。 The top portion 21 supports a lid plate 23 that opens and closes the opening 22. The manner in which the cover plate 23 is supported is not particularly limited. For example, the top part 21 and the lid plate 23 may be integrally molded so that they are bent at the hinge 24, or one end of the lid plate 23 molded separately from the top part 21 may be fitted to the top part 21. good.

蓋板２３は、該蓋板２３が開口部２２を閉じたときに開口部２２に嵌合するリブ状の嵌合部２５を有する。 The lid plate 23 has a rib-shaped fitting portion 25 that fits into the opening 22 when the lid plate 23 closes the opening 22.

なお、蓋板２３を開くときに蓋板２３の自由端２３ａの天面部２１からの引き上げを容易にするため、図示した態様では自由端２３ａに対応する天面部２１の外形は上面視で開口部２２方向に湾曲している。一方、本発明においては天面部２１の外形に対して蓋板２３の自由端２３ａを開口部２２とは逆方向に凸状に湾曲させても良い。 Note that in order to facilitate lifting of the free end 23a of the lid plate 23 from the top surface part 21 when opening the lid plate 23, in the illustrated embodiment, the outer shape of the top surface part 21 corresponding to the free end 23a is the same as the opening when viewed from above. It is curved in 22 directions. On the other hand, in the present invention, the free end 23a of the cover plate 23 may be curved convexly in the opposite direction to the opening 22 with respect to the outer shape of the top surface portion 21.

樹脂蓋２０は、天面部２１の周囲、好ましくは全周に袋体１０の外表面と貼着する貼着部２６を有する。図２に示すように、樹脂蓋２０の貼着部の裏面２６ｂには再剥離性の粘着層２７が設けられており、粘着層２７上には剥離シート（図示せず）が貼付されている。樹脂蓋２０を袋体１０に取り付けるときには、粘着層２７上の剥離シートを除去し、粘着層２７を袋体１０の外表面に押し当て、貼着部２６を押圧することにより樹脂蓋２０を袋体１０の外表面に付け替え可能に貼着する。 The resin lid 20 has an adhesive part 26 that adheres to the outer surface of the bag body 10 around the top surface part 21, preferably around the entire circumference. As shown in FIG. 2, a removable adhesive layer 27 is provided on the back surface 26b of the adhesive part of the resin lid 20, and a release sheet (not shown) is pasted on the adhesive layer 27. . When attaching the resin lid 20 to the bag body 10, remove the release sheet on the adhesive layer 27, press the adhesive layer 27 against the outer surface of the bag body 10, and press the adhesive part 26 to attach the resin lid 20 to the bag body. It is removably attached to the outer surface of the body 10.

なお、本発明において樹脂蓋２０の貼着部２６と袋体１０の外表面とを貼着する粘着層２７は、袋体１０に設けられていても良い。その場合、袋体の粘着層上には剥離シートが設けられる。 In the present invention, the adhesive layer 27 that adheres the adhesive part 26 of the resin lid 20 and the outer surface of the bag 10 may be provided on the bag 10. In that case, a release sheet is provided on the adhesive layer of the bag.

図４に示すように、樹脂蓋２０の天面部２１の裏面には、開口部２２を囲む環状リブ２８が設けられている。本実施例において環状リブ２８は、樹脂蓋２０の天面２１ａにおける開口部２２の縁部２２ａから起立し、天面２１ａと反対方向に突出しているが、樹脂蓋２０を袋体１０に取り付けた状態で環状リブ２８は袋体１０の内部にまでは突出していない。 As shown in FIG. 4, an annular rib 28 surrounding the opening 22 is provided on the back surface of the top surface 21 of the resin lid 20. As shown in FIG. In this embodiment, the annular rib 28 stands up from the edge 22a of the opening 22 on the top surface 21a of the resin lid 20 and protrudes in the opposite direction to the top surface 21a. In this state, the annular rib 28 does not protrude into the interior of the bag body 10.

図５に示すように、環状リブ２８が突出する基面２９は、貼着部２６と袋体１０との貼着面３０よりも天面（即ち、天面部２１の表面）２１ａ側に位置している。これにより、樹脂蓋２０の裏面は、環状リブ２８の外周に該環状リブ２８に隣接する裏面凹部３１を有する。したがって、樹脂蓋２０の開口部２２と袋体１０のシート取出口１２とを合わせて樹脂蓋２０の貼着部２６の粘着層２７を袋体１０の外表面に押圧することにより樹脂蓋２０を袋体１０に取り付ける際に、環状リブ２８がこの押圧に支障をきたすことはなく、樹脂蓋２０の貼着部２６を袋体１０の外表面に容易に押圧することができる。また、この押圧時に環状リブ２８が袋体１０内のシート材２に強く押さえ付けられることはなく、シート材２の押さえ付けによる液体のしみ出しが抑制される。さらに、裏面凹部３１が液体を保持する液溜め機能を有するので、図５に矢印で示すようにシート材２から液体がしみ出た場合でも、しみ出た液体が樹脂蓋２０と袋体１０との貼着面３０に浸出することが防止される。したがって、この樹脂蓋２０によれば、シート材２からしみ出た液体によって、樹脂蓋２０と袋体１０との貼着力が低減することが防止される。よって、樹脂蓋２０が袋体１０から不用意に外れることを防止するために、特許文献１に記載のようなコの字状の断面形状を樹脂蓋に設けることは不要であり、必要に応じて樹脂蓋を洗浄し、衛生的に樹脂蓋の使用を継続することが可能となる。 As shown in FIG. 5, the base surface 29 from which the annular rib 28 projects is located closer to the top surface (i.e., the surface of the top surface portion 21) 21a than the adhesive surface 30 between the adhesive portion 26 and the bag body 10. ing. As a result, the back surface of the resin lid 20 has a back surface recess 31 adjacent to the annular rib 28 on the outer periphery of the annular rib 28 . Therefore, by aligning the opening 22 of the resin lid 20 and the sheet outlet 12 of the bag body 10 and pressing the adhesive layer 27 of the adhesive part 26 of the resin lid 20 against the outer surface of the bag body 10, the resin lid 20 is closed. When attached to the bag body 10, the annular rib 28 does not interfere with this pressing, and the adhesive portion 26 of the resin lid 20 can be easily pressed against the outer surface of the bag body 10. Further, during this pressing, the annular rib 28 is not strongly pressed against the sheet material 2 within the bag body 10, and the seepage of liquid due to the pressing of the sheet material 2 is suppressed. Furthermore, since the back recess 31 has a liquid reservoir function for holding liquid, even if the liquid seeps out from the sheet material 2 as shown by the arrow in FIG. leaching onto the adhesive surface 30 is prevented. Therefore, according to this resin lid 20, the adhesive force between the resin lid 20 and the bag body 10 is prevented from being reduced due to the liquid seeping out from the sheet material 2. Therefore, in order to prevent the resin lid 20 from accidentally coming off from the bag body 10, it is not necessary to provide the resin lid with a U-shaped cross-sectional shape as described in Patent Document 1, and it is not necessary to provide the resin lid with a U-shaped cross-sectional shape as described in Patent Document 1. It becomes possible to wash the resin lid and continue using it hygienically.

本発明において、環状リブ２８の基面２９からの高さｈは、この基面２９からの樹脂蓋と袋体との貼着面３０の高さｈ0 の－０．２５ｍｍ～＋０．５ｍｍが好ましく、言い換えると、これらの高さの差（Δｈ＝ｈ－ｈ0）が上述の範囲にあることが好ましく、±０ｍｍであること、即ち、環状リブ２８の先端と貼着面３０とが面一であることがより好ましい。高さｈを上述の範囲とすることにより樹脂蓋２０を袋体１０に取り付ける際の樹脂蓋２０と袋体１０との押圧に環状リブ２８が支障をきたさず、かつ環状リブ２８により形成される裏面凹部３１に液溜め機能を良好に発揮させることができる。 In the present invention, the height h of the annular rib 28 from the base surface 29 is -0.25 mm to +0.5 mm of the height h 0 of the adhesive surface 30 between the resin lid and the bag body from the base surface 29. In other words, it is preferable that the difference in height (Δh=h−h 0 ) is within the above-mentioned range, and is ±0 mm, that is, the tip of the annular rib 28 and the adhesion surface 30 are flush with each other. It is more preferable that the number is one. By setting the height h within the above-mentioned range, the annular rib 28 does not interfere with the pressing between the resin lid 20 and the bag body 10 when attaching the resin lid 20 to the bag body 10, and the annular rib 28 is formed by the annular rib 28. It is possible to make the back surface recess 31 exhibit a good liquid reservoir function.

環状リブ２８は、開口部２２の周りの全周に形成されていることが好ましいが、その高さｈは、前述のΔｈ＝－０．２５ｍｍ～＋０．５ｍｍの範囲で変動してもよい。 The annular rib 28 is preferably formed around the entire circumference of the opening 22, but its height h may vary within the aforementioned range of Δh=-0.25 mm to +0.5 mm.

本発明の樹脂蓋及び包装体は種々の変形態様をとることができる。
例えば、図６に示すように、環状リブ２８は、樹脂蓋の天面２１ａにおける開口部の縁部２２ａからではなく、その近傍から起立してもよい。この場合、縁部２２ａと環状リブ２８との水平方向の距離ｄは５ｍｍ以内とすることが好ましい。 The resin lid and package of the present invention can be modified in various ways.
For example, as shown in FIG. 6, the annular rib 28 may stand up not from the edge 22a of the opening on the top surface 21a of the resin lid, but from the vicinity thereof. In this case, the horizontal distance d between the edge 22a and the annular rib 28 is preferably within 5 mm.

また、本発明の包装体において袋体１０のシート取出口１２は、図３に示したように樹脂蓋２０の開口部２２内にあってもよく、図６に示したようにシート取出口１２の縁部１２ａが環状リブ２８の直下にあってもよく、図７に示すようにシート取出口１２の縁部１２ａが裏面凹部３１の下にあってもよい。樹脂蓋２０と袋体１０との貼着面３０に、シート材２からしみ出た液体が浸出しにくくする点からは、袋体１０のシート取出口１２が樹脂蓋２０の開口部２２内にあることが最も好ましく、続いて袋体１０のシート取出口１２の縁部１２ａが環状リブ２８の直下にある場合が、液体が浸出しにくい。 Furthermore, in the package of the present invention, the sheet outlet 12 of the bag 10 may be located within the opening 22 of the resin lid 20 as shown in FIG. The edge 12a of the sheet outlet 12 may be located directly below the annular rib 28, or the edge 12a of the sheet outlet 12 may be located below the back recess 31, as shown in FIG. In order to prevent the liquid seeping from the sheet material 2 from seeping out onto the adhesive surface 30 between the resin lid 20 and the bag body 10, the sheet outlet 12 of the bag body 10 is placed inside the opening 22 of the resin lid 20. The most preferable case is that the edge 12a of the sheet outlet 12 of the bag body 10 is located directly below the annular rib 28, in which case the liquid is difficult to seep out.

上述した本発明の変形態様は適宜組み合わせることができる。 The above-described modifications of the present invention can be combined as appropriate.
