Description

この発明は、例えば指先でつまんで折り曲げることで開く開口予定部を有し、収容部に収容された内容物を開いた開口予定部から押し出す折り曲げ開封包装体に関する。   The present invention relates to a folded and opened package that has a planned opening portion that is opened by pinching with a fingertip, for example, and extrudes the contents accommodated in the accommodation portion from the planned opening portion.

折り曲げ開封包装体は、たとえば調味料や飲料などの食品や、化粧品、医薬品などの個別包装に好適に使用されている。   The folded and opened package is suitably used for individual packaging of foods such as seasonings and beverages, cosmetics and pharmaceuticals, for example.

折り曲げ開封包装体は、貫通形成された開口予定部を塞いでいる閉鎖シートを折り曲げによって破ってその開口予定部を開いたり、折り曲げで破断可能な非貫通の開口予定部を折り曲げによって開いたりして、内容物を押し出し可能にするものである。このような折り曲げ包装体には、内容物を収容する収容部が開口予定部を開く折り曲げ動作によって圧縮される部位に形成されており、開口予定部を開く折り曲げ動作と内容物を押し出す押し出し動作が一連に行われる構成のものがある。このほかに、収容部が開口予定部を開く折り曲げ動作によって圧縮される部位から外して形成されており、開口予定部を開く折り曲げ動作と内容物を押し出す押し出し動作が別である構成のものもある。   Bending and unwrapping package is to open the planned opening portion by folding the closing sheet covering the planned opening portion formed by penetration, or by opening the planned non-through opening portion that can be broken by folding. The content can be extruded. In such a folded package body, the accommodating portion for containing the contents is formed at a portion compressed by the bending operation for opening the planned opening portion, and the folding operation for opening the planned opening portion and the extrusion operation for pushing out the contents are performed. There are configurations that are performed in series. In addition, there is a configuration in which the accommodating portion is formed to be removed from the portion compressed by the bending operation for opening the planned opening portion, and the folding operation for opening the planned opening portion and the push-out operation for pushing out the contents are different. .

いずれの構成の場合でも内容物は押し出されるので、勢いよく押し出すと内容物が一挙に吐出されて、周囲に飛び散ることがある。特に、開口予定部を開く折り曲げ動作と内容物を押し出す押し出し動作が一連に行われる構成の折り曲げ開封包装体では、折り曲げを行って開口予定部を開くと同時に内容物が飛び出すので、内容物が飛び散るおそれが高い。   In any case, the contents are pushed out, and if pushed out vigorously, the contents may be discharged all at once and scattered around. In particular, in a folded unwrapped package with a structure in which a folding operation for opening the planned opening and an extrusion operation for extruding the contents are performed in series, the contents pop out because the contents pop out at the same time as opening the planned opening. There is a high risk.

このため、下記特許文献1に開示の構成を案出した。この構成は、開口予定部に、開口予定部から押し出される内容物に接触して抵抗を付与する流動抵抗付与部を備えるというものである。流動抵抗付与部はフィルムで構成されている。   For this reason, the configuration disclosed in Patent Document 1 below has been devised. In this configuration, the planned opening portion is provided with a flow resistance imparting portion that contacts the contents pushed out from the planned opening portion and imparts resistance. The flow resistance imparting portion is composed of a film.

この構成では、別体の流動抵抗付与部を備える必要があるので、必要な部品点数が増すことになる。   In this configuration, since it is necessary to provide a separate flow resistance applying portion, the number of necessary parts increases.

特許第5802769号公報Japanese Patent No. 5802769

この発明は、内容物が飛び散ることを簡素な構成で防止できるようにすることを主な目的とする。   The main object of the present invention is to prevent the contents from scattering with a simple configuration.

そのための手段は、折り曲げによって開く開口予定部を有し、収容部に収容された内容物を前記開口予定部から押し出す折り曲げ開封包装体であって、前記収容部と前記開口予定部の間に、前記内容物を前記開口予定部に向けて導く導出部が形成され、前記導出部の始端側部位に、前記収容部よりも幅狭の隘路部が形成され、前記導出部の終端側部位に、前記隘路部よりも幅広で前記開口予定部に対向する開口室が形成された折り曲げ開封包装体である。   Means therefor is a folded opening packaging body that has a planned opening portion that is opened by bending, and pushes out the contents accommodated in the accommodating portion from the planned opening portion, between the accommodating portion and the planned opening portion, A lead-out portion that guides the contents toward the planned opening portion is formed, a narrow passage narrower than the housing portion is formed in a start-end side portion of the lead-out portion, and a terminal-side portion of the lead-out portion, It is a folded open packaging body that is wider than the bottleneck part and has an opening chamber that faces the planned opening part.

ここで、「幅狭」または「幅広」とは、導出部において内容物が流動する際における内容物が導かれる方向に直交する平面視での長さの長短(広狭)と、直交する方向での断面積の大小をいう。この概念は、隘路部や開口室が偏平な場合には、主にその長さと、内容物が流れる際の断面積で認識され、立体的な場合には、主にその断面積で認識される。   Here, “narrow” or “wide” refers to the length (wide or narrow) of the length in plan view orthogonal to the direction in which the content is guided when the content flows in the outlet, and the direction orthogonal to The size of the cross-sectional area. This concept is recognized mainly by the length and the cross-sectional area when the contents flow when the bottleneck and the opening chamber are flat, and mainly by the cross-sectional area when the contents are three-dimensional. .

この構成では、押されることで収容部から導出部に出ようとする内容物が、隘路によって一旦絞られてから開口室に出る。この際に内容物にかかる圧力が解放され、このあとで、内容物は開かれた開口予定部から出される。   In this configuration, the content to be pushed out from the storage portion to the lead-out portion by being pushed is once squeezed by the bottleneck and then comes out to the opening chamber. At this time, the pressure applied to the contents is released, and then the contents are taken out from the opened opening.

この発明によれば、収容部と開口予定部の間に導出部を備えて、押し出される内容物にかかる圧力を緩和するので、内容物が飛び散ることを防止できる。そのうえ、導出部は収容部と同様に構成できるので、別体の部材を不要にすることができ、また簡素な構成とすることもできる。   According to the present invention, since the lead-out portion is provided between the accommodating portion and the planned opening portion and the pressure applied to the extruded content is relieved, the content can be prevented from scattering. In addition, since the lead-out portion can be configured in the same manner as the housing portion, a separate member can be dispensed with and the configuration can be simplified.

この発明を実施するための一形態を、以下図面を用いて説明する。   An embodiment for carrying out the present invention will be described below with reference to the drawings.

図1に、折り曲げ開封包装体11(以下、「包装体」という)の斜視図を示す。この包装体11は、上下反転して指先でつまんで側面視V字状に折り曲げることで開封して、内容物Xを押し出すものである。この例では、折り曲げられると完全に重なり合う中間位置で2つ折りして押し出す構成を示すが、その他の折り曲げ形態であってもよい。また内容物Xには、液状やペースト状のほかに、粉体や粒体などの固状、さらにはそれらの混合状態のものがある。   FIG. 1 shows a perspective view of a folded and opened package 11 (hereinafter referred to as “package”). The package 11 is flipped upside down, pinched with a fingertip, folded in a V-shape in side view, and the contents X are pushed out. In this example, a configuration is shown in which it is folded and extruded at an intermediate position where it completely overlaps when folded, but other folding forms are also possible. In addition to the liquid and paste forms, the contents X include solid forms such as powders and granules, and those in a mixed state.

包装体11は、分解斜視図である図2に示したように、内容物Xを収容する容体としての容器シート13と、容器シート13を閉じる蓋体としての蓋シート15を有しており、容器シート13には内容物Xを収容する収容部31が形成され、蓋シート15には折り曲げによって開く開口予定部51が形成されている。収容部31は開口予定部51を開く折り曲げによって圧縮される部位に形成されている。収容部31に収容されている内容物Xは、折り曲げによって開いた開口予定部51の開口から押し出される。この構成では、容器シート13と蓋シート15がこの発明のシート材に対応する構成である。   As shown in FIG. 2, which is an exploded perspective view, the packaging body 11 includes a container sheet 13 as a container that contains the contents X, and a lid sheet 15 as a lid that closes the container sheet 13. The container sheet 13 is formed with an accommodating portion 31 for accommodating the contents X, and the lid sheet 15 is formed with a planned opening portion 51 that is opened by bending. The accommodating part 31 is formed in the site | part compressed by the bending which opens the opening scheduled part 51. FIG. The contents X accommodated in the accommodating part 31 are pushed out from the opening of the planned opening part 51 opened by bending. In this configuration, the container sheet 13 and the lid sheet 15 correspond to the sheet material of the present invention.

包装体11の基本的な構成はつぎのとおりである。   The basic configuration of the package 11 is as follows.

容器シート13は、変形可能で柔軟性を有する合成樹脂製のシート材で形成されており、内容物Xを収容する前述の収容部31が凹状に形成されている。蓋シート15は、容器シート13における収容部31の開口した上面を閉塞するものであり、合成樹脂からなる折り曲げ可能な板状である。この蓋シート15の折り曲げ位置Pに、折り曲げ時に開口して収容部31内の内容物Xを押し出す開口予定部51が形成されている。つまり包装体11は、折り曲げることで開く開口予定部51を有した板状の蓋シート15の下面に、容器シート13の上端部を貼り合わせて一体化した構成である。   The container sheet 13 is formed of a deformable and flexible synthetic resin sheet material, and the above-described accommodating portion 31 that accommodates the contents X is formed in a concave shape. The lid sheet 15 closes the upper surface of the container sheet 13 where the accommodating portion 31 is opened, and is a foldable plate shape made of synthetic resin. At the folding position P of the lid sheet 15, a planned opening portion 51 that is opened when the lid sheet 15 is folded and pushes out the contents X in the housing portion 31 is formed. That is, the package 11 has a configuration in which the upper end portion of the container sheet 13 is bonded to and integrated with the lower surface of the plate-like lid sheet 15 having the planned opening portion 51 that is opened by bending.

開口予定部51は、蓋シート15の厚さ方向に予め貫通形成されており、折り曲げ動作で破れる封止シート17で閉じられている。このほか、折り曲げ動作で剥がれる封止シートで閉じたものや、折り曲げで破断可能な非貫通状態であり、折り曲げた際に破断して貫通状態となって開口するハーフカット構造もの(図示せず)であってもよい。   The planned opening 51 is formed in advance in the thickness direction of the lid sheet 15 and is closed by the sealing sheet 17 that is torn by the bending operation. In addition, those that are closed with a sealing sheet that is peeled off by a bending operation, or in a non-penetrating state that can be broken by folding, and that have a half-cut structure that breaks and opens when folded (not shown) It may be.

各部について具体的に説明すると、容器シート13の形状は、平面視長方形状であり、上面の全周に、平面視長方形枠状をなす適宜幅の上端鍔部32を有している。上端鍔部32より内側に、前述の収容部31が形成されている。   If it demonstrates concretely about each part, the shape of the container sheet | seat 13 will be a planar view rectangular shape, and it has the upper end collar part 32 of the width | variety which makes | forms the planar view rectangular frame shape in the perimeter of an upper surface. The above-described accommodating portion 31 is formed inside the upper end flange portion 32.

収容部31は、折り曲げ方向である長辺方向の中間位置、つまり前述の折り曲げ位置Pに対応する位置を対称軸とする対称形状であり、長辺方向の両側に全体として直方体状に凹んだ収容部31を有している。一対の収容部31は、適宜の間隔をあけて離間配置されている。2個の収容部31には、同一の内容物Xが収容されても、別の内容物Xが収容されてもよく、各収容部31は必要な量の内容物Xを収容可能な大きさである。   The accommodating part 31 has a symmetrical shape with the intermediate position in the long side direction as the bending direction, that is, the position corresponding to the above-described bending position P as the axis of symmetry, and is recessed in a rectangular parallelepiped shape as a whole on both sides in the long side direction. A portion 31 is provided. The pair of accommodating portions 31 are spaced apart from each other with an appropriate interval. The two storage units 31 may store the same content X or different content X, and each storage unit 31 is large enough to store a necessary amount of the content X. It is.

容器シート13における蓋シート15の開口予定部51とその周囲に対応する部分、つまり一対の収容部31の間の中間部33は、収容部31のような凹みのない平坦な形状である。   The planned opening portion 51 of the lid sheet 15 in the container sheet 13 and a portion corresponding to the periphery thereof, that is, the intermediate portion 33 between the pair of storage portions 31 has a flat shape without a recess like the storage portion 31.

容器シート13を構成するシート材には、柔軟でありながら強度を有しており、ガスバリア性に優れて深絞り成形性のよい適宜の合成樹脂製フィルムが使用される。このようなフィルムとしては、例えば三菱ケミカル株式会社製の「ダイアミロン」(登録商標)がある。フィルムの厚さは100μm程度あるとよい。   As the sheet material constituting the container sheet 13, an appropriate synthetic resin film that is flexible but has strength, excellent gas barrier properties, and good deep drawability is used. An example of such a film is “Diamilon” (registered trademark) manufactured by Mitsubishi Chemical Corporation. The thickness of the film is preferably about 100 μm.

蓋シート15は、容器シート13の上端部の外周縁と一致する大きさの平面視長方形状である。この蓋シート15は、柔軟な容器シート13と内容物Xを支えるとともに、折り曲げた際に内容物Xの入った容器シート13を挟み込み、折り曲げ位置Pにおける折り曲げを可能とするものであって、適宜の硬さを有している。蓋シート15は、容器シート13の収容部31に内容物Xを入れた後に、容器シート13の上端部に対して溶着等で結合一体化される。   The lid sheet 15 has a rectangular shape in a plan view having a size matching the outer peripheral edge of the upper end portion of the container sheet 13. The lid sheet 15 supports the flexible container sheet 13 and the contents X, and sandwiches the container sheet 13 containing the contents X when folded, and enables folding at the folding position P. It has the hardness of. The lid sheet 15 is combined and integrated with the upper end portion of the container sheet 13 by welding or the like after the contents X are put into the accommodating portion 31 of the container sheet 13.

この蓋シート15は、その拡大断面図である図3に示したように積層構造である。具体的には、硬質シート15aの表裏両面にシール材15bを積層一体化した構成である。硬質シート15aには、たとえば厚さ0.3mm程度のアモルファスポリエチレンテレフタレートを使用できる。シール材15bには、厚さ15μm程度のポリエチレン製のフィルムが使用可能である。これらの積層一体化は、ドライラミネート加工で行える。   The lid sheet 15 has a laminated structure as shown in FIG. 3 which is an enlarged sectional view thereof. Specifically, the sealing material 15b is laminated and integrated on both front and back surfaces of the hard sheet 15a. For the hard sheet 15a, for example, amorphous polyethylene terephthalate having a thickness of about 0.3 mm can be used. As the sealing material 15b, a polyethylene film having a thickness of about 15 μm can be used. These lamination and integration can be performed by dry lamination.

蓋シート15の折り曲げ位置Pは、図1に示したように、長辺方向の中間位置における短辺方向と平行な線上である。この折り曲げ位置Pの長手方向(包装体11の短辺方向)の中間位置には、前述の開口予定部51が形成され、この開口予定部51を短辺方向で挟む両側には、折り曲げのための補助となる折り曲げ罫線53が形成されている。   The bending position P of the lid sheet 15 is on a line parallel to the short side direction at the intermediate position in the long side direction, as shown in FIG. The above-mentioned planned opening portion 51 is formed at an intermediate position in the longitudinal direction of the folding position P (the short side direction of the package 11), and the both sides sandwiching the planned opening portion 51 in the short side direction are bent. A folding ruled line 53 is formed to assist the above.

図3における(a)の図は、図1のA−A位置、つまり開口予定部51位置で切断した蓋シート15の断面図であり、図3における(b)の図は、図1のB−B位置、つまり折り曲げ罫線53位置で切断した蓋シート15の断面図である。これらの図に示すように、開口予定部51は、蓋シート15の厚み方向に貫通する切り込みであり、折り曲げ罫線53は厚み方向に非貫通で上面(表面)側から形成された切り込みである。   3A is a cross-sectional view of the lid sheet 15 cut at the position AA in FIG. 1, that is, the position of the planned opening portion 51, and FIG. 3B is a cross-sectional view of FIG. It is sectional drawing of the lid | cover sheet | seat 15 cut | disconnected by -B position, ie, the folding ruled line 53 position. As shown in these drawings, the planned opening portion 51 is a cut that penetrates in the thickness direction of the lid sheet 15, and the folding ruled line 53 is a cut that is not penetrated in the thickness direction and is formed from the upper surface (front surface) side.

開口予定部51の形状や大きさは内容物Xの種類や性状、折り曲げ態様などに応じて適宜設計される。この例の開口予定部51は、折り曲げ位置Pの長手方向に延びる波線形状に形成されている。つまり平面視半円弧状の切り込みが交互に連続した形状の開口予定部51である。   The shape and size of the planned opening 51 are appropriately designed according to the type and properties of the contents X, the bending mode, and the like. The planned opening 51 in this example is formed in a wavy shape extending in the longitudinal direction of the bending position P. That is, it is the planned opening portion 51 having a shape in which cuts having a semicircular arc shape in plan view are alternately continued.

図4の(a)〜(f)に開口予定部51の形状についての他の例を示す。図4は、封止シート17なしの包装体11の平面図である。この図においては、折り曲げ罫線53の図示は、便宜上省略している。   Other examples of the shape of the planned opening 51 are shown in FIGS. FIG. 4 is a plan view of the package 11 without the sealing sheet 17. In this figure, the folding ruled lines 53 are not shown for convenience.

(a)の開口予定部51は、折り曲げ位置Pの長手方向に延びる直線形状に形成されている。(b)の開口予定部51は、折り曲げ位置Pの長手方向と直交する短辺方向に膨らむ円弧線形状に形成されている。この形状の開口予定部51では、封止シート17の破断が円滑に行えるとともに、より大きな開口が得られる。(c)の開口予定部51は、折り曲げ位置Pの長手方向に延びる直線形状の本体部51aと、この本体部51aの両端に形成されて、折り曲げ位置Pの長手方向に直角の方向にのびる端部切り込み51bを有する形状である。この形状の開口予定部51でも、より大きな開口が得られる。(d)の開口予定部51は、図1、図2に示した前述のような波線形状の本体部51aの両端に、折り曲げ位置Pの長手方向に対して斜めに延びる端部切り込み51bを有した形状である。(e)の開口予定部51は、折り曲げ位置Pの長手方向に延びる直線形状の本体部51aの両端に、折り曲げ位置Pの長手方向に対して斜めに延びる端部切り込み51bを有した形状である。(f)の開口予定部51は、折り曲げ位置Pの長手方向に延びる直線形状の本体部51aの両端の端部切り込み51bに加えて、それより内側に寄った位置にも、折り曲げ位置Pの長手方向に直角の方向にのびる内部切り込み51cを有した形状である。内部切り込み51cは端部切り込み51bよりも長く形成されている。   The planned opening portion 51 in (a) is formed in a linear shape extending in the longitudinal direction of the bending position P. The planned opening 51 in (b) is formed in an arcuate line shape that swells in the short side direction orthogonal to the longitudinal direction of the bending position P. In the opening planned portion 51 having this shape, the sealing sheet 17 can be smoothly broken and a larger opening can be obtained. (C) The planned opening 51 is a linear main body 51a extending in the longitudinal direction of the bending position P and ends formed at both ends of the main body 51a and extending in a direction perpendicular to the longitudinal direction of the bending position P. This is a shape having a part cut 51b. Even in the opening planned portion 51 having this shape, a larger opening can be obtained. The planned opening 51 in (d) has end cuts 51b extending obliquely with respect to the longitudinal direction of the folding position P at both ends of the wavy main body 51a as shown in FIGS. Shape. The planned opening portion 51 of (e) has a shape having end cuts 51 b extending obliquely with respect to the longitudinal direction of the folding position P at both ends of the linear body portion 51 a extending in the longitudinal direction of the folding position P. . In addition to the end notches 51b at both ends of the linear main body 51a extending in the longitudinal direction of the folding position P, the planned opening portion 51 in (f) is also provided at the position closer to the inner side than the longitudinal length of the folding position P. It has a shape having an internal cut 51c extending in a direction perpendicular to the direction. The internal cut 51c is formed longer than the end cut 51b.

これらの例のように開口予定部51の形状は適宜設計できる。   As in these examples, the shape of the planned opening 51 can be designed as appropriate.

蓋シート15における開口予定部51を有する領域の表面は、前述の封止シート17で覆われる。封止シート17は、貫通している開口予定部51を閉じて容器シート13内を気密状態に保つとともに、開口予定部51が開くときに破れる性質のシート材で構成される。これには、例えばアルミニウム箔などの金属箔を使用できる。具体的には、封止シート17は、厚さ11μm程度のアルミニウム箔に、ヒートシール可能なアクリル・コポリマーをコーティングして構成するとよい。封止シート17は蓋シート15に対して溶着により積層一体化される。   The surface of the region having the scheduled opening 51 in the lid sheet 15 is covered with the sealing sheet 17 described above. The sealing sheet 17 is made of a sheet material having a property of closing the scheduled opening portion 51 penetrating to keep the inside of the container sheet 13 in an airtight state and tearing when the scheduled opening portion 51 is opened. For this, for example, a metal foil such as an aluminum foil can be used. Specifically, the sealing sheet 17 may be formed by coating an aluminum foil having a thickness of about 11 μm with a heat-sealable acrylic copolymer. The sealing sheet 17 is laminated and integrated with the lid sheet 15 by welding.

前述のような容器シート13と蓋シート15で構成される包装体11は、容器シート13の収容部31と蓋シート15の開口予定部51の間に、収容部31内の内容物Xを開口予定部51に向けて導く導出部41を有している。導出部41の始端側部位、つまり収容部31側の部位には、収容部31よりも幅狭の隘路部42が形成されており、導出部41の終端側部位には、隘路部42よりも幅広で開口予定部51に対向する開口室部43が形成されている。開口室部43は、包装体11の上下方向・厚み方向で開口予定部51に対向している。   The packaging body 11 composed of the container sheet 13 and the lid sheet 15 as described above opens the contents X in the housing portion 31 between the housing portion 31 of the container sheet 13 and the planned opening portion 51 of the lid sheet 15. It has a derivation section 41 that leads toward the planned section 51. A narrow channel portion 42 narrower than the accommodating portion 31 is formed at the start side portion of the lead-out portion 41, that is, the portion on the accommodating portion 31 side. An opening chamber portion 43 is formed which is wide and faces the planned opening portion 51. The opening chamber portion 43 faces the planned opening portion 51 in the up-down direction and the thickness direction of the package 11.

具体的には、前述のように収容部31を、開口予定部51を挟んで対向配置しており、2個備えているので、これらの間に形成される開口室部43は、2個の収容部31に共通のものである。つまり、2個の収容部31に別々に収容された内容物Xは開口室部43で合流する。開口室部43の大きさ・容積は、収容部31の容積や、内容物Xの性状や量、開口予定部51の形状等の条件に応じて適宜設定されるが、大きめに形成するほうが好ましい。   Specifically, as described above, the accommodating portion 31 is disposed opposite to each other with the planned opening portion 51 interposed therebetween, and thus two opening chamber portions 43 formed therebetween are provided. This is common to the accommodating portion 31. That is, the contents X separately accommodated in the two accommodating portions 31 merge at the opening chamber portion 43. The size and volume of the opening chamber portion 43 are appropriately set according to conditions such as the volume of the accommodating portion 31, the property and amount of the contents X, the shape of the planned opening portion 51, etc., but it is preferable to form a larger size. .

開口室部43は平面視方形状に形成されており、収容部31のように深絞り成形した立体形状ではなく、平面的な偏平形状である。   The opening chamber portion 43 is formed in a square shape in a plan view, and is not a three-dimensional shape that is deep-drawn like the housing portion 31 but a planar flat shape.

隘路部42は、2個の収容部31の一部から開口室部43の一部に向けて、それぞれ1個ずつ形成される。隘路部42は、収容部31と開口室部43にとって狭い通路、すなわち隘路であって、適宜の大きさ(幅)に形成される。隘路部42の長さも適宜設定できる。この隘路部42も、開口室部43と同様で、収容部31のように深絞り成形した立体形状ではなく、平面的な偏平形状である。   One bottleneck part 42 is formed from a part of the two accommodating parts 31 toward a part of the opening chamber part 43. The bottleneck part 42 is a narrow passage for the storage part 31 and the opening chamber part 43, that is, a bottleneck, and is formed in an appropriate size (width). The length of the bottleneck part 42 can also be set as appropriate. The bottleneck portion 42 is also similar to the opening chamber portion 43, and is not a three-dimensional shape that is deep-drawn like the housing portion 31, but is a flat, flat shape.

このような形状の導出部41の形成は、蓋シート15を容器シート13の上端部に貼り合わせて一体化する際の、一体化の範囲の設定で行われる。   Formation of the lead-out portion 41 having such a shape is performed by setting an integration range when the lid sheet 15 is bonded to the upper end portion of the container sheet 13 and integrated.

図5は、容器シート13の平面図であり、前述の一体化を行う範囲(以下、「貼り合わせ部45」という)を示している。貼り合わせ部45は、図5中の点を施した部分であり、上端鍔部32の全部と、一対の収容部31の間の中間部33における中央部分を除く部分である。   FIG. 5 is a plan view of the container sheet 13 and shows a range in which the above-described integration is performed (hereinafter referred to as “bonding portion 45”). The pasting portion 45 is a portion given a point in FIG. 5, and is a portion excluding the entire upper end flange portion 32 and the central portion in the intermediate portion 33 between the pair of accommodating portions 31.

平坦な中間部33の中央部分が導出部41を形成する部分であって、シート材同士、つまり容器シート13と蓋シート15を貼り合わせないで浮かせた非貼り合わせ部46である。   A central portion of the flat intermediate portion 33 is a portion forming the lead-out portion 41, and is a non-bonded portion 46 that is floated without bonding the sheet materials, that is, the container sheet 13 and the lid sheet 15.

非貼り合わせ部46は、平面視方形状をなし開口室部43を形成する1個の開口室形成部35と、開口室形成部35から収容部31側に延びて隘路部42を形成する2個の隘路形成部36を有している。開口室形成部35は、蓋シート15の開口予定部51に対応する部分を囲む大きさであって、収容部31の対向方向における収容部31間の大きさよりも小さい。隘路形成部36は、開口室形成部35における収容部31の対向方向と直交する短辺方向の長さよりもの短く狭い。また2個の隘路形成部36は収容部31の対向方向で対向している。より具体的には隘路形成部36は、収容部31と開口室形成部35における収容部31の対向方向と直交する短辺方向の中間位置に形成されている。   The non-bonding portion 46 has a square shape in plan view and forms one opening chamber forming portion 35 that forms the opening chamber portion 43, and 2 extends from the opening chamber forming portion 35 toward the accommodating portion 31 to form the narrow passage portion 42. There are individual bottleneck forming portions 36. The opening chamber forming portion 35 has a size that surrounds a portion corresponding to the planned opening portion 51 of the lid sheet 15, and is smaller than the size between the storage portions 31 in the facing direction of the storage portion 31. The bottleneck forming part 36 is narrower and narrower than the length in the short side direction orthogonal to the facing direction of the accommodating part 31 in the opening chamber forming part 35. Further, the two bottleneck forming portions 36 face each other in the facing direction of the accommodating portion 31. More specifically, the bottleneck formation portion 36 is formed at an intermediate position in the short side direction orthogonal to the facing direction of the accommodation portion 31 in the accommodation portion 31 and the opening chamber formation portion 35.

なお、開口室形成部35と隘路形成部36は、収容部31のように凹状に形成してもよい。   The opening chamber forming portion 35 and the bottleneck forming portion 36 may be formed in a concave shape like the housing portion 31.

前述の貼り合わせ部45と非貼り合わせ部46を有する一体化を行うことで、導出部41は形成される。図6に、包装体11の平面図(図6(a))と正面図(図6(b))を示す。   The lead-out portion 41 is formed by performing the integration including the bonding portion 45 and the non-bonding portion 46 described above. FIG. 6 shows a plan view (FIG. 6A) and a front view (FIG. 6B) of the package 11.

図6(b)に見られるように、導出部41は偏平な形状である。また、導出部41と開口予定部51の大きさの関係は、図6(a)に寸法線で示したように設定されている。すなわち、収容部31が最も幅広であり、以下、開口室部43、開口予定部51、隘路部42の順に幅狭となる。図6中、W1は収容部31の幅、W2は開口室部43の幅、W3は開口予定部51の幅、W4は隘路部42の幅である。   As seen in FIG. 6B, the lead-out portion 41 has a flat shape. Further, the relationship between the size of the lead-out portion 41 and the planned opening portion 51 is set as shown by the dimension line in FIG. That is, the accommodating part 31 is the widest, and becomes narrow in the order of the opening chamber part 43, the opening plan part 51, and the bottleneck part 42 below. In FIG. 6, W <b> 1 is the width of the accommodating portion 31, W <b> 2 is the width of the opening chamber portion 43, W <b> 3 is the width of the planned opening portion 51, and W <b> 4 is the width of the bottleneck portion 42.

なお、図示例の形状の場合には、収容部31と隘路部42と開口室部43は、収容部31の対向方向、つまり内容物Xが導出部41を通る方向での幅の変化がないか、もしくはごく少ない形状であるが、前述した各部の「幅」とは、最小位置での幅の意味である。   In the case of the shape of the illustrated example, the accommodating portion 31, the bottleneck portion 42, and the opening chamber portion 43 have no change in width in the facing direction of the accommodating portion 31, i. Although the shape is very small, the “width” of each part described above means the width at the minimum position.

また、各部の大きさの違いを表現するのに、前述のように「幅広」又は「幅狭」と、短辺方向の長さ、つまり導出部41において内容物Xが導かれる方向に直交する方向のうち容器シート13の上端面の面方向での長さで表現したが、各部の大きさは、平面視での単なる長さと、内容物Xが流れる際の断面積の双方の観点から認識されるものである。   In order to express the difference in the size of each part, as described above, “wide” or “narrow” is perpendicular to the length in the short side direction, that is, the direction in which the content X is guided in the derivation unit 41. Although expressed in the length in the surface direction of the upper end surface of the container sheet 13 among the directions, the size of each part is recognized from the viewpoint of both the mere length in plan view and the cross-sectional area when the contents X flow It is what is done.

収容部31は平面視で最も幅広である上に立体的な形状であるので、他の部位と比較して格段に幅広である。   Since the accommodating portion 31 is widest in a plan view and has a three-dimensional shape, it is much wider than other portions.

開口室部43と隘路部42は共に立体的ではなく平面的、つまり偏平な形状であり、開口室部43は隘路部42よりも平面視で幅広であるので、内容物Xが流れる際の断面積の点でも幅広となる。   Both the opening chamber 43 and the narrow passage 42 are not three-dimensional but planar, that is, flat, and the opening chamber 43 is wider than the narrow passage 42 in plan view. It is also wide in terms of area.

開口予定部51は開口室部43よりも平面視において幅狭であるので、一義的には開口室部43よりも幅狭であるが、開口室部43は偏平な形状である一方、開口予定部51は前述のように開口を大きくすることもできるので、開口予定部51は開口室部43よりも幅広となることもある。   Since the planned opening portion 51 is narrower than the opening chamber portion 43 in plan view, it is uniquely narrower than the opening chamber portion 43. However, while the opening chamber portion 43 has a flat shape, the planned opening portion 51 Since the opening of the part 51 can be enlarged as described above, the planned opening part 51 may be wider than the opening chamber part 43.

また開口予定部51は、隘路部42と比べると、隘路部42よりも平面視において幅広であり、開口予定部51は開くものの、その開き方は実質的には偏平な隘路部42が膨らむのと同様であるので、開口予定部51は隘路部42よりも幅広である。   Further, the planned opening portion 51 is wider than the narrow passage portion 42 in plan view, and although the planned opening portion 51 opens, the flat narrow passage portion 42 swells in a substantially open manner. Therefore, the planned opening portion 51 is wider than the bottleneck portion 42.

隘路部42と開口室部43と開口予定部51の大きさの相違、つまり「幅広」又は「幅狭」の程度は適宜設定される。例えば、隘路部42は開口室部43の10%から90%程度の大きさにすることができる。同様に、隘路部42は開口予定部51の5%から90%程度の大きさにすることができる。   Differences in the sizes of the bottleneck portion 42, the opening chamber portion 43, and the planned opening portion 51, that is, the degree of “wide” or “narrow” is appropriately set. For example, the bottleneck portion 42 can be about 10% to 90% of the size of the open chamber portion 43. Similarly, the narrow part 42 can be about 5% to 90% of the planned opening part 51.

以上のように構成された包装体11では、収容部31に収容された内容物Xを次のように排出する。   In the package 11 configured as described above, the contents X accommodated in the accommodating portion 31 are discharged as follows.

まず、手に持った包装体11を、図7の(a)に示したように、上下反転して蓋シート15を下にし、開口予定部51、換言すれば封止シート17の中心を押し出し方向に向ける。そのまま、指先で蓋シート15における長手方向の端縁部や、それよりも折り曲げ位置P寄りの部分をつまんで、内容物Xの入った容器シート13をつぶすように蓋シート15を二つ折りにする(図7の(b)参照)。   First, as shown in FIG. 7A, the packaging body 11 held in the hand is turned upside down so that the lid sheet 15 faces downward, and the opening opening 51, in other words, the center of the sealing sheet 17 is pushed out. Turn in the direction. As it is, the lid sheet 15 is folded in half so that the container sheet 13 containing the contents X is crushed by pinching the edge of the lid sheet 15 in the longitudinal direction with the fingertip and the portion closer to the folding position P. (See FIG. 7B).

すると、蓋シート15に挟まれて圧縮されることによって、容器シート13の内部の圧力が高まるとともに、蓋シート15の折り曲げ位置Pが変形する。この変形に追従しない封止シート17は破断して、蓋シート15の開口予定部51が開いて内容物Xが押し出される。   Then, by being sandwiched and compressed by the lid sheet 15, the pressure inside the container sheet 13 is increased and the folding position P of the lid sheet 15 is deformed. The sealing sheet 17 that does not follow this deformation breaks, the opening scheduled portion 51 of the lid sheet 15 opens, and the contents X are pushed out.

内容物Xの排出に先立って、収容部31の内容物Xは、図7の(b)に示したように、導出部41の隘路部42に入ってから開口室部43に流れ込む。導出部41は偏平な形状であるので、通常は内容物Xの進入が抑制されているが、蓋シート15を折り曲げると、開口室部43は折り曲げの内側に位置するので弛んで、内容物Xの流入によって膨らむ。このあと、開口室部43の内容物Xは、折り曲げによって開いた開口予定部51の開口から後続の内容物Xに押されるようにして押し出される。   Prior to the discharge of the contents X, the contents X in the storage part 31 flow into the opening chamber 43 after entering the bottleneck part 42 of the lead-out part 41 as shown in FIG. Since the lead-out portion 41 has a flat shape, the entry of the content X is normally suppressed. However, when the lid sheet 15 is folded, the opening chamber portion 43 is located on the inner side of the folding, so that the content X is loosened. Inflates due to the inflow of. Thereafter, the contents X in the opening chamber 43 are pushed out by the subsequent contents X from the opening of the planned opening 51 opened by bending.

このよう過程を経て押し出される内容物Xは、図8の(a)に矢印で示したように、導出部41を通る過程で圧力の変化を受ける。すなわち、広い収容部31から隘路部42に入る際に内容物Xには圧力がかかり、流動が抑制される。つづいて隘路部42から開口室部43に流入するときには内容物Xが解放され、圧力が緩和される。先に開口室部43に入った内容物Xは、後続の内容物Xの勢いをそぐ。このあと内容物Xは、圧力が解かれた状態で、開口予定部51に開いた開口を通って排出される。   The content X pushed out through such a process is subjected to a change in pressure in the process of passing through the derivation unit 41 as indicated by an arrow in FIG. That is, when entering the bottleneck part 42 from the wide accommodating part 31, a pressure is applied to the content X, and a flow is suppressed. Subsequently, when the fluid flows into the opening chamber portion 43 from the narrow passage portion 42, the contents X are released and the pressure is relieved. The content X that has entered the opening chamber portion 43 first removes the momentum of the subsequent content X. Thereafter, the content X is discharged through the opening opened in the planned opening 51 in a state where the pressure is released.

このため、内容物Xは勢いよく一挙に押し出されることはなく、勢いがよすぎて内容物Xが周囲に飛び散ることを防止できる。   For this reason, the content X is not pushed out at a stretch, and it is possible to prevent the content X from being scattered around due to excessive momentum.

包装体11の収容部31は、開口予定部51を開く折り曲げによって圧縮される部位に形成されており、開口予定部51を開く動作と内容物Xを押し出す動作が一連に行われるものであるが、前述のように内容物Xが飛び散ることを防止できるので極めて有益である。   The accommodating part 31 of the package 11 is formed in a portion that is compressed by bending to open the planned opening part 51, and the operation of opening the planned opening part 51 and the operation of pushing out the contents X are performed in series. As described above, the contents X can be prevented from scattering, which is extremely useful.

開口室部43は折り曲げた際に内側になる位置に形成されているので、たるみやすい。このため、内容物Xの流入によって膨らみ、折り曲げ前は偏平な形態であっても、圧力の緩和が極めて良好に行える。   Since the opening chamber portion 43 is formed at a position that becomes the inner side when it is bent, it is easy to sag. For this reason, it swells by the inflow of the contents X, and the pressure can be relieved very well even if it is flat before bending.

しかも、そのための導出部41の形成には、別部材が不要である。そのうえ、導出部41は貼り合わせ部45と非貼り合わせ部46を有する一体化で構成できるので、構成が簡素なうえに製造も容易である。   In addition, no separate member is required to form the lead-out portion 41 for that purpose. In addition, since the lead-out part 41 can be configured as an integrated unit having the bonding part 45 and the non-bonding part 46, the structure is simple and the manufacture is easy.

また、収容部31は開口予定部51を挟んで対向配置されており、隘路部42が収容部31の対向方向で対向しているので、2個の隘路部42を通って開口室部43に流れ込む内容物Xが、開口室部43に入ってすぐに合流するので、内容物Xが良好に混ざり合う。   In addition, the accommodating portion 31 is disposed so as to sandwich the planned opening portion 51, and the narrow passage portion 42 is opposed in the facing direction of the accommodating portion 31, so that it passes through the two narrow passage portions 42 to the opening chamber portion 43. Since the contents X that flow in join the opening chamber part 43 immediately, the contents X mix well.

さらに、導出部41が非貼り合わせ部46で形成されており偏平な形態であるので、内容物Xの押し出し前の状態において、導出部41に内容物Xが進入することを抑制できので、開口予定部51に内容物Xが触れる機会を少なくできる。   Further, since the lead-out portion 41 is formed by the non-bonding portion 46 and has a flat shape, it is possible to prevent the content X from entering the lead-out portion 41 in the state before the content X is pushed out, so that the opening The opportunity for the contents X to touch the planned portion 51 can be reduced.

以下、その他の例について説明する。この説明において、前述の構成と同一の構成については同一の符号を付してその詳しい説明を省略する。   Hereinafter, other examples will be described. In this description, the same components as those described above are denoted by the same reference numerals, and detailed description thereof is omitted.

図9は、他の例に係る包装体11の平面図と正面図であり、この包装体11は全体して偏平な板状である。つまり、平面図である図9の(a)に示したように平面視長方形である。   FIG. 9 is a plan view and a front view of a package 11 according to another example, and the package 11 has a flat plate shape as a whole. That is, it is a rectangular shape in plan view as shown in FIG.

基本的な構成は図1の包装体11と同じであるが、この例では主に、容器シート13が立体的に成形されていない点で図1の包装体11とは相違する。容器シート13は、蓋シート15と同様に平面視長方形状である。   Although the basic configuration is the same as that of the package 11 in FIG. 1, this example is mainly different from the package 11 in FIG. 1 in that the container sheet 13 is not three-dimensionally formed. Similar to the lid sheet 15, the container sheet 13 has a rectangular shape in plan view.

開口予定部51は図1の包装体11と同様に、中央位置に形成されており、包装体11の長手方向の中間が折り曲げ位置Pであって、収容部31は、開口予定部51を包装体11の長手方向に挟んで対向配置されている。折り曲げ位置Pは短辺方向に延びている。   The planned opening portion 51 is formed at the center position in the same manner as the packaging body 11 of FIG. 1, and the middle in the longitudinal direction of the packaging body 11 is the bending position P, and the accommodating portion 31 packages the planned opening portion 51. Oppositely arranged across the longitudinal direction of the body 11. The bending position P extends in the short side direction.

包装体11は、開口予定部51に対向する部位に、開口予定部51を収める大きさの開口室部43を有し、この開口室部43は平面視円形である。開口室部43には、収容部31に連通する隘路部42が包装体11の長手方向に沿って形成されている。一対の隘路部42は相対向している。隘路部42の最も幅狭の部分はごく短く、開口室部43が隘路部42から徐々に大きく広がる形状に形成されることになる。   The package 11 has an opening chamber 43 having a size that accommodates the planned opening 51 at a portion facing the planned opening 51, and the opening 43 is circular in plan view. In the opening chamber portion 43, a narrow passage portion 42 communicating with the housing portion 31 is formed along the longitudinal direction of the package body 11. The pair of bottleneck portions 42 are opposed to each other. The narrowest part of the narrow part 42 is very short, and the opening chamber 43 is formed in a shape that gradually widens from the narrow part 42.

つまり、収容部31と導出部41を形成する貼り合わせ部45及び非貼り合わせ部46は、次のような態様で形成されている。貼り合わせ部45は、容器シート13及び蓋シート15の全周と、折り曲げ位置Pに対応する部位のうち、開口室部43を除く位置と、開口室部43を取り囲む円を描く部位のうち隘路部42を除く位置である。   That is, the bonding part 45 and the non-bonding part 46 which form the accommodating part 31 and the derivation | leading-out part 41 are formed in the following aspects. The laminating portion 45 is a bottleneck among the entire circumference of the container sheet 13 and the lid sheet 15, the portion corresponding to the bending position P, the position excluding the opening chamber portion 43, and the portion drawing a circle surrounding the opening chamber portion 43. This is the position excluding the part 42.

この例においても、収容部31と、開口室部43と、開口予定部51と、隘路部42の大きさは、この順で小さくなるように形成されている。このように全体が偏平な形態の包装体11では、各部の大きさの違いは、主に導出部41において内容物Xが導かれる方向に直交する平面視での長さで認識される。   Also in this example, the accommodating part 31, the opening chamber part 43, the scheduled opening part 51, and the narrow part 42 are formed so as to be smaller in this order. Thus, in the package 11 having a flat shape as a whole, the difference in the size of each part is recognized mainly by the length in plan view orthogonal to the direction in which the contents X are guided in the derivation part 41.

このような構成の包装体11においては、収容される内容物Xの量が図1の包装体11よりも少ないだけで、前述と同様の作用を有し、効果を奏する。   The package 11 having such a configuration has the same effects as described above and has an effect only when the amount of the contents X to be contained is smaller than that of the package 11 shown in FIG.

図10は、他の例に係る包装体11の平面図であり、この包装体11は、図9の包装体11と同様に板状であっても、図1の包装体11と同様に立体的な形状であってもいずれでもよい。   FIG. 10 is a plan view of a packaging body 11 according to another example. Even if the packaging body 11 has a plate shape like the packaging body 11 of FIG. 9, the packaging body 11 is three-dimensional like the packaging body 11 of FIG. 1. It may be either a typical shape.

包装体11の収容部31が開口予定部51を挟んで対向配置されている点や折り曲げ位置Pが短辺方向に延びている点などは、前述の包装体11の場合と同様であるが、収容部31は平面視円形に形成され、一対の収容部31を連通させる導出部41は平面視略ひし形に形成されている。   The point that the accommodating portion 31 of the package 11 is disposed opposite to the opening planned portion 51, the point that the bending position P extends in the short side direction, and the like are the same as in the case of the package 11 described above. The accommodating portion 31 is formed in a circular shape in plan view, and the lead-out portion 41 that communicates the pair of accommodating portions 31 is formed in a generally rhombic shape in plan view.

この例おいても、収容部31と、開口室部43と、開口予定部51と、隘路部42の大きさは、この順で小さくなるように形成されている。   Also in this example, the accommodating part 31, the opening chamber part 43, the scheduled opening part 51, and the bottleneck part 42 are formed so as to be smaller in this order.

このような構成の包装体11は、前述と同様の作用を有し、効果を奏する。   The package 11 having such a configuration has the same operation as described above, and has an effect.

効果についてはそのほか特に、収容部31が平面視円形であるので、内容物Xを一回の折り曲げ動作でより完全に排出することができる利点がある。   Regarding the effect, in particular, since the accommodating portion 31 is circular in plan view, there is an advantage that the contents X can be more completely discharged by a single folding operation.

図11は、他の例に係る包装体11の平面図であり、この包装体11は、開口予定部51を短辺方向(折り曲げ位置Pの長手方向)の一方に偏らせた例を示している。この包装体11も板状であっても、立体的な形状であってもよい。   FIG. 11 is a plan view of a package 11 according to another example, and this package 11 shows an example in which the planned opening 51 is biased to one side in the short side direction (longitudinal direction of the folding position P). Yes. The package 11 may be plate-shaped or three-dimensional.

収容部31は開口予定部51を挟んで対向配置されており、折り曲げ位置Pは包装体11の長手方向の中間位置において短辺方向に延びている。   The accommodating portion 31 is disposed so as to sandwich the planned opening portion 51, and the bending position P extends in the short side direction at an intermediate position in the longitudinal direction of the package body 11.

開口予定部51は、折り曲げ位置Pの長手方向の一方に形成されており、このため、開口室部43は短辺方向の一方に寄せて形成されている。隘路部42は、外周縁に形成される貼り合わせ部45に沿って、収容部31の対向方向で対向している。   The planned opening portion 51 is formed on one side in the longitudinal direction of the bending position P. For this reason, the opening chamber portion 43 is formed close to one side in the short side direction. The bottleneck part 42 is opposed in the facing direction of the accommodating part 31 along the bonding part 45 formed on the outer peripheral edge.

図12に、容器シート13と蓋シート15の分離状態の平面図を示しており、この図に示したように、容器シート13における折り曲げ位置Pに対応する部分の長手方向の他方には、非貼り合わせ部46aが形成されている。この非貼り合わせ部46aは、蓋シート15に形成される折り曲げ罫線53が、貼り合わせ部45の形成に伴う溶融によって本来の機能を減殺してしまうことを回避するためのものである。   FIG. 12 shows a plan view of the container sheet 13 and the lid sheet 15 in a separated state. As shown in this figure, the other side in the longitudinal direction of the portion corresponding to the bending position P in the container sheet 13 A bonding portion 46a is formed. The non-bonding portion 46 a is for avoiding that the folded ruled line 53 formed on the lid sheet 15 diminishes the original function due to melting accompanying the formation of the bonding portion 45.

このような構成の包装体11は、前述と同様の作用を有し、効果を奏する。   The package 11 having such a configuration has the same operation as described above, and has an effect.

効果についてはそのほか特に、開口予定部51が短辺方向の一方の端に位置しているので、内容物Xを押し出した際に、蓋シート15の表面に付着する内容物Xの量を低減することができる。   Regarding the effect, in particular, since the planned opening portion 51 is located at one end in the short side direction, the amount of the content X adhering to the surface of the lid sheet 15 is reduced when the content X is pushed out. be able to.

図13は、他の例に係る包装体11の平面図であり、この包装体11は、開口予定部51を短辺方向(折り曲げ位置Pの長手方向)の中央に形成しつつも、隘路部42を短辺方向の一方に偏らせた例を示している。この包装体11も板状であっても、立体的な形状であってもよい。   FIG. 13 is a plan view of a packaging body 11 according to another example, and this packaging body 11 has a bottleneck portion while forming the planned opening portion 51 at the center in the short side direction (longitudinal direction of the bending position P). The example which biased 42 to one side of the short side direction is shown. The package 11 may be plate-shaped or three-dimensional.

収容部31は開口予定部51を挟んで対向配置されており、折り曲げ位置Pは包装体11の長手方向の中間位置において短辺方向に延びている。   The accommodating portion 31 is disposed so as to sandwich the planned opening portion 51, and the bending position P extends in the short side direction at an intermediate position in the longitudinal direction of the package body 11.

開口予定部51は、折り曲げ位置Pの長手方向の中間位置に形成され、開口室部43は、開口予定部51を包含する大きさの長方形状に形成されている。開口室部43の大きさについて具体的に言えば、収容部31の幅と同じ幅に設定されている。そして隘路部42は、開口室部43の短辺方向における端に形成されている。   The planned opening portion 51 is formed at an intermediate position in the longitudinal direction of the bending position P, and the opening chamber portion 43 is formed in a rectangular shape having a size including the planned opening portion 51. More specifically, the size of the opening chamber 43 is set to the same width as the width of the accommodating portion 31. The bottleneck portion 42 is formed at the end of the opening chamber portion 43 in the short side direction.

図13の(a)は、隘路部42を収容部31の対向方向で対向させた例であり、(b)は対向方向で非対向とした例である。具体的には、図13の(b)の2個の隘路部42は、開口室部43の短辺方向の一方の端と、他方の端に向けて形成されている。   FIG. 13A is an example in which the bottleneck portion 42 is opposed in the facing direction of the accommodating portion 31, and FIG. 13B is an example in which the opposite direction is not opposed. Specifically, the two bottleneck portions 42 in FIG. 13B are formed toward one end in the short side direction of the opening chamber 43 and the other end.

このような構成の包装体11では、隘路部42が開口予定部51から離れているので、隘路部42を通って開口室部43に入った内容物Xが開口室部43で十分に混ざってから開口予定部51より排出される。   In the package 11 having such a configuration, since the narrow passage portion 42 is separated from the planned opening portion 51, the contents X that have entered the open chamber portion 43 through the narrow passage portion 42 are sufficiently mixed in the open chamber portion 43. From the planned opening 51.

図14は、他の例に係る包装体11の平面図であり、この包装体11は、1個の収容部31と1個の導出部41を有する構造である。この包装体11の収容部31は板状であっても、立体的な形状であってもよく、収容部31がシート材で偏平な袋状に形成された包装体11にも適用できる。   FIG. 14 is a plan view of a package body 11 according to another example, and this package body 11 has a structure having one accommodating portion 31 and one lead-out portion 41. The container 31 of the package 11 may be plate-shaped or three-dimensional, and can be applied to the package 11 in which the container 31 is formed in a flat bag shape with a sheet material.

図14は、収容部31が偏平な袋状である例であり、包装体11の全体が柔軟なシート材からなる平坦な2枚の容器シート13を互いに貼り合わせて構成されている。つまり、容器シート13がこの発明のシート材に対応する構成であって、収容部31と導出部41における内容物Xが接する部分は容器シート13で構成されている。   FIG. 14 shows an example in which the accommodating portion 31 has a flat bag shape, and the entire package 11 is formed by bonding two flat container sheets 13 made of a flexible sheet material to each other. In other words, the container sheet 13 corresponds to the sheet material of the present invention, and the portion where the contents X in the accommodating portion 31 and the lead-out portion 41 are in contact is constituted by the container sheet 13.

包装体11は一方側の大半の部分に収容部31を有し、他方側の端に導出部41を有している。収容部31は、長方形の他方側を絞って徐々に幅狭となる形状に形成されており、導出部41は、収容部31における幅狭となった一方の端に連設されている。導出部41は平面視方形である。   The package 11 has the accommodating part 31 in the most part of one side, and has the derivation | leading-out part 41 in the end of the other side. The accommodating portion 31 is formed in a shape that gradually narrows by narrowing the other side of the rectangle, and the lead-out portion 41 is connected to one end of the accommodating portion 31 that is narrowed. The derivation | leading-out part 41 is a planar view square shape.

図14のC−C断面図を、図15に示している。この図に示すように、導出部41の片面に、導出部41に略等しい大きさの蓋シート15を備えている。蓋シート15は片面の全体が容器シート13に貼り付けられている。   FIG. 15 is a cross-sectional view taken along the line CC of FIG. As shown in this figure, a cover sheet 15 having a size substantially equal to that of the derivation unit 41 is provided on one surface of the derivation unit 41. The entire lid sheet 15 is affixed to the container sheet 13.

蓋シート15には、蓋シート15を短辺方向に二つ折りする折り曲げ位置Pを有しており、折り曲げ位置Pの長手方向の中間部に開口予定部51が形成されている。容器シート13における蓋シート15の開口予定部51に対応する部位には、折り曲げによって開く同様の開口予定部37が形成されている。   The lid sheet 15 has a folding position P at which the lid sheet 15 is folded in the short side direction, and a planned opening portion 51 is formed at the middle portion of the folding position P in the longitudinal direction. A similar opening planned portion 37 that is opened by bending is formed at a portion of the container sheet 13 corresponding to the planned opening portion 51 of the lid sheet 15.

このような構成の包装体11は、収容部31が、開口予定部37,51を開く折り曲げによって圧縮される部位以外の部位に形成されている。   The package 11 having such a configuration is formed in a portion other than the portion where the accommodating portion 31 is compressed by bending to open the planned opening portions 37 and 51.

内容物Xの排出に際しては、まず蓋シート15を二つ折りして開口予定部51,37を開き、その上で収容部31を押して内容物Xを押し出す。内容物Xが流体の場合には、導出部41を下に向けるだけで、内容物Xを押し出す動作をするまでもなく内容物Xが滴下することもある。   When discharging the contents X, the lid sheet 15 is first folded in half to open the scheduled openings 51 and 37, and then the container 31 is pushed to push out the contents X. When the content X is a fluid, the content X may be dripped only by directing the lead-out portion 41 downward without needing to push out the content X.

図16は、他の例に係る包装体11の平面図であり、この包装体11も、収容部31が偏平な袋状である例である。包装体11は全体が平面視方形状であり、その一つの角部に、導出部41が形成されている。導出部41は三角形状である。導出部41を形成するための貼り合わせ部45は、包装体11の縦横方向に対して斜めに延びる線状に形成されている。   FIG. 16 is a plan view of a package body 11 according to another example, and this package body 11 is also an example in which the accommodating portion 31 has a flat bag shape. The entire package 11 has a square shape in plan view, and a lead-out portion 41 is formed at one corner thereof. The derivation unit 41 has a triangular shape. The bonding portion 45 for forming the lead-out portion 41 is formed in a linear shape extending obliquely with respect to the vertical and horizontal directions of the package 11.

このような構成の包装体11においては、図14、図15の包装体11と同様の作用を有し、効果を奏する。   The package 11 having such a configuration has the same operation as the package 11 shown in FIGS.

以上はこの発明を実施するための一形態の構成であって、この発明は前述の構成のみに限定されるものではなく、その他の構成を採用することもできる。   The above is a configuration of one embodiment for carrying out the present invention, and the present invention is not limited to the above-described configuration, and other configurations can be adopted.

例えば折り曲げ方は前述のような二つ折りのほかに、適宜の折り方を採用でき、折り曲げ位置Pにおいてきれいに折り曲げられる折り方の場合には、折り曲げ罫線53を省略することもできる。   For example, in addition to the above-described bi-folding, an appropriate folding method can be adopted, and the folding ruled line 53 can be omitted in the case of a folding method in which folding is performed at the folding position P.
