　以下、好適な実施形態に基づき、図面を参照して本発明を説明する。 Hereinafter, the present invention will be described with reference to the drawings based on the preferred embodiments.
　図１に、本発明の一実施形態に係る容器を示す。この容器１０は、注出口１４を有する天面部材１１と、一端部に天面部材１１が接合された筒状部材１２と、筒状部材１２の他端部に接合された底面部材１３とを有して、略円筒状に構成されている。この容器１０は、自立性を有する。容器１０の自立性とは、少なくとも内容物を充填した状態で自立が可能な性質である。さらには、内容物を充填していない状態でも容器１０の自立が可能であることが好ましい。 FIG. 1 shows a container according to an embodiment of the present invention. The container 10 includes a top surface member 11 having a spout 14, a tubular member 12 having the top surface member 11 joined to one end, and a bottom surface member 13 joined to the other end of the tubular member 12. It has a substantially cylindrical shape. The container 10 is self-supporting. The independence of the container 10 is a property that allows the container 10 to become independent at least in a state of being filled with the contents. Furthermore, it is preferable that the container 10 can stand on its own even when the contents are not filled.
　天面部材１１は、自立時に上面となり、底面部材１３は、自立時に下面となる。筒状部材１２は、天面部材１１と底面部材１３との間で、上下方向に交差する周方向を覆うように形成されている。容器１０は、天面部材１１と、筒状部材１２と、底面部材１３とをそれぞれ１枚ずつ組み合わせた３パーツから構成することができる。 The top surface member 11 becomes the upper surface when it stands on its own, and the bottom surface member 13 becomes the lower surface when it stands on its own. The tubular member 12 is formed so as to cover the circumferential direction intersecting in the vertical direction between the top surface member 11 and the bottom surface member 13. The container 10 can be composed of three parts in which a top surface member 11, a tubular member 12, and a bottom surface member 13 are combined one by one.
　天面部材１１、筒状部材１２、及び底面部材１３は、樹脂フィルム、ラミネートフィルム等のフィルムから構成することができる。樹脂フィルムは、単層の樹脂フィルムでもよく、多層の樹脂フィルムでもよい。ラミネートフィルムにおいて、樹脂と積層する異種材料としては、金属箔、金属蒸着層、紙等が挙げられる。ラミネートフィルムは、異種材料の少なくとも片面に樹脂層を有する。バリア性、剛性等の観点から、ラミネートフィルムがアルミニウム箔等の金属箔を含むことが好ましい。 The top surface member 11, the tubular member 12, and the bottom surface member 13 can be made of a film such as a resin film or a laminated film. The resin film may be a single-layer resin film or a multi-layer resin film. Examples of different materials to be laminated with the resin in the laminated film include metal foil, metal vapor deposition layer, and paper. The laminated film has a resin layer on at least one side of a dissimilar material. From the viewpoint of barrier property, rigidity and the like, it is preferable that the laminated film contains a metal foil such as an aluminum foil.
　図２及び図３に示すように、天面部材１１と筒状部材１２との接合部は、天面部材１１の周縁部１１ｂを天面部１１ａに対して屈曲させ、筒状部材１２の内面に対向させて構成することができる。天面部材１１の天面部１１ａとは、注出口１４が設けられるフィルムの部分である。図２に示す第１実施形態では、周縁部１１ｂにおいて天面部材１１の内面が筒状部材１２の内面と接合されている。このため、周縁部１１ｂは、天面部材１１の表側に屈曲されている。図３に示す第２実施形態では、周縁部１１ｂにおいて天面部材１１の外面が筒状部材１２の内面と接合されている。このため、周縁部１１ｂは、天面部材１１の裏側に屈曲されている。特に図示しないが、天面部材１１の周縁部１１ｂが筒状部材１２の外面と接合されてもよい。天面部材１１の周縁部１１ｂが筒状部材１２の端部に対して環状に接合されることにより、接合強度を高めることができる。 As shown in FIGS. 2 and 3, the joint portion between the top surface member 11 and the tubular member 12 is formed on the inner surface of the tubular member 12 by bending the peripheral edge portion 11b of the top surface member 11 with respect to the top surface portion 11a. It can be configured to face each other. The top surface portion 11a of the top surface member 11 is a portion of the film provided with the spout 14. In the first embodiment shown in FIG. 2, the inner surface of the top surface member 11 is joined to the inner surface of the tubular member 12 at the peripheral edge portion 11b. Therefore, the peripheral edge portion 11b is bent toward the front side of the top surface member 11. In the second embodiment shown in FIG. 3, the outer surface of the top surface member 11 is joined to the inner surface of the tubular member 12 at the peripheral edge portion 11b. Therefore, the peripheral edge portion 11b is bent to the back side of the top surface member 11. Although not particularly shown, the peripheral edge portion 11b of the top surface member 11 may be joined to the outer surface of the tubular member 12. The bonding strength can be increased by joining the peripheral edge portion 11b of the top surface member 11 to the end portion of the tubular member 12 in an annular shape.
　注出口１４は、天面部１１ａを貫通する流路１５を含む筒状部１４ａを有する。この流路１５により、容器１０に充填される内容物を、天面部材１１の裏側から表側に取り出すことができる。また、注出口１４は、天面部１１ａの表側の面に密着する第１フランジ部１４ｂと、天面部１１ａの裏側の面に密着する第２フランジ部１４ｃとを有する。天面部１１ａは、第１フランジ部１４ｂと第２フランジ部１４ｃとの間に挟み込まれている。以下の説明では、第１フランジ部１４ｂと第２フランジ部１４ｃとを総称して、フランジ部１４ｂ，１４ｃという場合がある。 The spout 14 has a tubular portion 14a including a flow path 15 penetrating the top surface portion 11a. Through this flow path 15, the contents filled in the container 10 can be taken out from the back side to the front side of the top surface member 11. Further, the spout 14 has a first flange portion 14b that is in close contact with the front surface of the top surface portion 11a and a second flange portion 14c that is in close contact with the back surface of the top surface portion 11a. The top surface portion 11a is sandwiched between the first flange portion 14b and the second flange portion 14c. In the following description, the first flange portion 14b and the second flange portion 14c may be collectively referred to as flange portions 14b and 14c.
　本実施形態では、天面部１１ａは円形であり、フランジ部１４ｂ，１４ｃも円形である。フランジ部１４ｂ，１４ｃの平面形状としては、円形、楕円形、多角形等が挙げられる。フランジ部１４ｂ，１４ｃの平面形状における多角形としては、例えば三角形、四角形、五角形、六角形、七角形、八角形等の凸多角形、星形等の凹多角形が挙げられる。第１フランジ部１４ｂの平面形状と第２フランジ部１４ｃの平面形状との関係は任意であり、互いに筒状部材１２の軸方向に重なり合う合同な図形でもよく、径方向の寸法が異なる相似形でもよく、軸周りに角度がずれた形状でもよく、互いに異なる形状でもよい。フランジ部１４ｂ，１４ｃの平面形状が、中心から１又は２以上の方向に延びた形状でもよく、例えば十字状、卍字状のように３以上の放射状に延びた形状でもよい。フランジ部１４ｂ，１４ｃの平面形状が、中心に対して点対称に延びた形状又は中心を通る線に対して線対称な形状等が好ましい。後述するように、溶融樹脂からフランジ部１４ｂ，１４ｃを成形する際、溶融樹脂が流れやすい形状が好ましい。フランジ部１４ｂ，１４ｃの肉厚は均一でもよく、中心から離れるほど薄くしてもよい。 In the present embodiment, the top surface portion 11a is circular, and the flange portions 14b and 14c are also circular. Examples of the planar shape of the flange portions 14b and 14c include a circular shape, an elliptical shape, and a polygonal shape. Examples of the polygon in the planar shape of the flange portions 14b and 14c include a convex polygon such as a triangle, a quadrangle, a pentagon, a hexagon, a hexagon, and an octagon, and a concave polygon such as a star. The relationship between the planar shape of the first flange portion 14b and the planar shape of the second flange portion 14c is arbitrary, and may be a congruent figure that overlaps with each other in the axial direction of the tubular member 12, or a similar shape having different radial dimensions. Often, the shapes may be offset around the axis, or may be different from each other. The planar shape of the flange portions 14b and 14c may be a shape extending in one or two or more directions from the center, or may be a shape extending radially of three or more such as a cross shape or a swastika shape. It is preferable that the planar shapes of the flange portions 14b and 14c extend point-symmetrically with respect to the center or line-symmetrically with respect to the line passing through the center. As will be described later, when the flange portions 14b and 14c are molded from the molten resin, a shape in which the molten resin easily flows is preferable. The wall thickness of the flange portions 14b and 14c may be uniform, or may be thinner as the distance from the center increases.
　筒状部１４ａと第１フランジ部１４ｂと第２フランジ部１４ｃとが、樹脂の一体成形により継目なく形成することができる。天面部１１ａは、筒状部１４ａのうち、第１フランジ部１４ｂと第２フランジ部１４ｃとの間の部分が挿通される開口部１１ｄを有する。開口部１１ｄの平面形状は、円形、楕円形、多角形等、閉じた図形であることが好ましい。これにより、開口縁部１１ｃが全周にわたり切れ目のない構造となる。開口縁部１１ｃとは、開口部１１ｄに接する天面部材１１の縁部である。 The tubular portion 14a, the first flange portion 14b, and the second flange portion 14c can be seamlessly formed by integrally molding the resin. The top surface portion 11a has an opening 11d through which a portion of the tubular portion 14a between the first flange portion 14b and the second flange portion 14c is inserted. The planar shape of the opening 11d is preferably a closed figure such as a circle, an ellipse, or a polygon. As a result, the opening edge portion 11c has a structure without a break over the entire circumference. The opening edge portion 11c is an edge portion of the top surface member 11 in contact with the opening portion 11d.
　上述の構造を有する注出口１４は、天面部１１ａの周囲に溶融樹脂を供給して、注出口１４を成形する方法により形成することができる。例えば図４に示すように、注出口１４の成形装置が、天面部材１１の裏側に配置されるキャビティー２１と、天面部材１１の表側に配置されるコア２２とからなる金型２０を有してもよい。注出口１４を成形する際の天面部材１１は、天面部１１ａ及び周縁部１１ｂを容器の形状に合わせて切断及び屈曲により形成する前の、より広い面積を有するフィルムであってもよい。注出口１４をインサート成形により製造する場合、天面部材１１は、注出口１４を構成する溶融樹脂の温度に耐える耐熱性を有することが好ましい。 The spout 14 having the above-mentioned structure can be formed by a method of forming the spout 14 by supplying a molten resin around the top surface portion 11a. For example, as shown in FIG. 4, the molding apparatus of the spout 14 has a mold 20 including a cavity 21 arranged on the back side of the top surface member 11 and a core 22 arranged on the front side of the top surface member 11. You may have. The top surface member 11 for molding the spout 14 may be a film having a wider area before the top surface portion 11a and the peripheral surface portion 11b are formed by cutting and bending according to the shape of the container. When the spout 14 is manufactured by insert molding, the top surface member 11 preferably has heat resistance to withstand the temperature of the molten resin constituting the spout 14.
　キャビティー２１とコア２２との間に形成される空間２４には、ゲート２３を介して溶融樹脂（図示せず）が供給される。ゲート跡が天面部材１１の裏側となることが好ましいことから、ゲート２３は、天面部材１１の裏側から溶融樹脂を供給することが好ましい。 A molten resin (not shown) is supplied to the space 24 formed between the cavity 21 and the core 22 via the gate 23. Since it is preferable that the gate mark is on the back side of the top surface member 11, it is preferable that the gate 23 supplies the molten resin from the back side of the top surface member 11.
　金型２０は、注出口１４の流路１５となる部分を塞ぐピン２５を有してもよい。ピン２５は、天面部材１１の開口部１１ｄの内部に挿通される。金型２０の空間２４に供給された溶融樹脂が固化すると、天面部材１１に密着するように注出口１４が成形される。ピン２５と開口縁部１１ｃとの間には溶融樹脂が通過可能な隙間が形成されているので、天面部材１１の裏側から供給される溶融樹脂が、天面部材１１の表側に達することができる。筒状部１４ａは、ピン２５の周囲に成形される。第１フランジ部１４ｂは、コア２２と天面部材１１の表側の面との間に成形される。第２フランジ部１４ｃは、キャビティー２１と天面部材１１の裏側の面との間に成形される。 The mold 20 may have a pin 25 that closes a portion of the spout 14 that serves as a flow path 15. The pin 25 is inserted into the opening 11d of the top surface member 11. When the molten resin supplied to the space 24 of the mold 20 solidifies, the spout 14 is formed so as to be in close contact with the top surface member 11. Since a gap through which the molten resin can pass is formed between the pin 25 and the opening edge portion 11c, the molten resin supplied from the back side of the top surface member 11 may reach the front side of the top surface member 11. it can. The tubular portion 14a is formed around the pin 25. The first flange portion 14b is formed between the core 22 and the front surface of the top surface member 11. The second flange portion 14c is formed between the cavity 21 and the back surface of the top surface member 11.
　天面部材１１が柔軟なフィルムから構成される場合、キャビティー２１とコア２２との間の空間２４内で、天面部材１１の開口縁部１１ｃが変位するおそれがある。開口縁部１１ｃの変位を抑制するため、図４では、流路１５となる部分の周囲で、開口部１１ｄの周方向にゲート２３を２箇所以上に配置している。これにより、溶融樹脂の流れが分散され、開口縁部１１ｃの変位を抑制することができる。 When the top surface member 11 is made of a flexible film, the opening edge portion 11c of the top surface member 11 may be displaced in the space 24 between the cavity 21 and the core 22. In order to suppress the displacement of the opening edge portion 11c, in FIG. 4, gates 23 are arranged at two or more locations in the circumferential direction of the opening portion 11d around the portion serving as the flow path 15. As a result, the flow of the molten resin is dispersed, and the displacement of the opening edge portion 11c can be suppressed.
　また、図４では、天面部材１１に向かって溶融樹脂を供給するゲート２３とは反対側の金型２０に、天面部材１１に向けて突出する突起２６を設けている。これにより、ゲート２３から供給される溶融樹脂の流れに抗して突起２６が天面部材１１の支えとなり、開口縁部１１ｃの変位を抑制することができる。突起２６が配置された箇所には溶融樹脂が供給されないことから、筒状部１４ａと第１フランジ部１４ｂとが連結するように、突起２６は、開口部１１ｄの周方向の一部に間欠的に形成することが好ましい。 Further, in FIG. 4, the mold 20 on the side opposite to the gate 23 that supplies the molten resin toward the top surface member 11 is provided with a protrusion 26 that protrudes toward the top surface member 11. As a result, the protrusion 26 serves as a support for the top surface member 11 against the flow of the molten resin supplied from the gate 23, and the displacement of the opening edge portion 11c can be suppressed. Since the molten resin is not supplied to the portion where the protrusion 26 is arranged, the protrusion 26 is intermittently provided in a part of the opening 11d in the circumferential direction so that the tubular portion 14a and the first flange portion 14b are connected to each other. It is preferable to form in.
　図５では、天面部材１１の開口縁部１１ｃに屈曲部１１ｅを設けている。開口縁部１１ｃが金型２０の内面に近接又は接触することにより、開口縁部１１ｃの変位を抑制することができる。また、図６では、天面部材１１の開口縁部１１ｃに材料を付加して補強層１６を積層している。補強層１６が金型２０の内面に近接又は接触することにより、開口縁部１１ｃの変位を抑制することができる。 In FIG. 5, a bent portion 11e is provided at the opening edge portion 11c of the top surface member 11. The displacement of the opening edge portion 11c can be suppressed by bringing the opening edge portion 11c close to or in contact with the inner surface of the mold 20. Further, in FIG. 6, a material is added to the opening edge portion 11c of the top surface member 11 to laminate the reinforcing layer 16. The displacement of the opening edge portion 11c can be suppressed by the reinforcing layer 16 approaching or contacting the inner surface of the mold 20.
　屈曲部１１ｅ及び補強層１６は、開口縁部１１ｃにおいてフィルムの厚さを増強する補強部として機能する。天面部材１１の表側の面に補強部が設けられていない箇所では、天面部材１１の表側の面とコア２２との間に第１フランジ部１４ｂが成形されるので、天面部材１１の表側の面に第１フランジ部１４ｂを密着させることができる。補強部は、開口部１１ｄの周囲に連続してリング状に形成してもよい。開口部１１ｄの周方向の一部に、補強部を間欠的に形成してもよい。同一の注出口１４に対して、屈曲部１１ｅ、補強層１６等の２種以上の補強部を組み合わせて用いることもできる。また、補強部を突起２６と組み合わせて用いることもできる。補強部は、開口部１１ｄに接する位置に設けることが好ましい。補強層１６を開口部１１ｄから離れた位置に設けてもよい。 The bent portion 11e and the reinforcing layer 16 function as a reinforcing portion for increasing the thickness of the film at the opening edge portion 11c. In a place where the reinforcing portion is not provided on the front surface of the top member 11, the first flange portion 14b is formed between the front surface of the top member 11 and the core 22, so that the top member 11 The first flange portion 14b can be brought into close contact with the front surface. The reinforcing portion may be continuously formed in a ring shape around the opening 11d. Reinforcing portions may be intermittently formed in a part of the opening portion 11d in the circumferential direction. Two or more types of reinforcing portions such as a bent portion 11e and a reinforcing layer 16 can be used in combination for the same spout 14. Further, the reinforcing portion can be used in combination with the protrusion 26. The reinforcing portion is preferably provided at a position in contact with the opening 11d. The reinforcing layer 16 may be provided at a position away from the opening 11d.
　図５及び図６では、ゲート２３が天面部材１１の裏側に配置されるので、補強部が少なくとも天面部材１１の表側の面で、コア２２の内面に近接又は接触するように設けられている。補強部は、天面部材１１の少なくともゲート２３とは反対側の面に設けることが好ましく、補強部を天面部材１１の両面に設けてもよい。天面部材１１の表側の面に補強部を設ける位置と、天面部材１１の裏側の面に補強部を設ける位置とが、互いに同一でもよく、互いに異なってもよい。 In FIGS. 5 and 6, since the gate 23 is arranged on the back side of the top surface member 11, the reinforcing portion is provided so as to be close to or in contact with the inner surface of the core 22 at least on the front side surface of the top surface member 11. There is. The reinforcing portion is preferably provided on at least the surface of the top surface member 11 opposite to the gate 23, and the reinforcing portion may be provided on both sides of the top surface member 11. The position where the reinforcing portion is provided on the front surface of the top surface member 11 and the position where the reinforcing portion is provided on the back surface of the top surface member 11 may be the same or different from each other.
　図７では、天面部材１１は、開口部１１ｄから離れた位置に貫通孔１７を有する。貫通孔１７は、天面部材１１の両面を貫通しているので、貫通孔１７を通じて、天面部材１１の表側の面に溶融樹脂が供給されやすくなり、第１フランジ部１４ｂを良好に成形しやすくなる。また、貫通孔１７の内部にも溶融樹脂が供給された状態で注出口１４が成形されることにより、貫通孔１７を通して第１フランジ部１４ｂを構成する樹脂と第２フランジ部１４ｃを構成する樹脂とが連結される。貫通孔１７は、ゲート２３と対向する位置に設けてもよい。開口部１１ｄから離れた位置の貫通孔１７と、開口縁部１１ｃにおける突起２６、屈曲部１１ｅ又は補強層１６の少なくとも１種以上とを、組み合わせて用いることもできる。 In FIG. 7, the top surface member 11 has a through hole 17 at a position away from the opening 11d. Since the through hole 17 penetrates both sides of the top surface member 11, the molten resin is easily supplied to the front surface of the top surface member 11 through the through hole 17, and the first flange portion 14b is satisfactorily formed. It will be easier. Further, the spout 14 is formed while the molten resin is also supplied to the inside of the through hole 17, so that the resin constituting the first flange portion 14b and the resin constituting the second flange portion 14c are formed through the through hole 17. And are connected. The through hole 17 may be provided at a position facing the gate 23. A through hole 17 located away from the opening 11d and at least one or more of a protrusion 26, a bent portion 11e, or a reinforcing layer 16 at the opening edge 11c can also be used in combination.

A barrier layer may be provided on the top surface member. When the flange portions are brought into close contact with both sides of the top surface member, sealant layers may be provided on both sides of the top surface member, and each sealant layer may be joined to each flange portion. Examples of the material constituting the sealant layer include polyolefin resins such as polyethylene (PE) and polypropylene (PP), polyester resins such as polyethylene terephthalate (PET), cycloolefin polymers (COP), and cycloolefin copolymers (COC). At least one or more of cyclic olefin resins such as, adhesive resins, and coating agents can be mentioned. As the barrier layer, an aluminum foil or an aluminum-deposited film is preferable. As the material constituting the base material layer, nylon (aliphatic polyamide), polyester and the like are preferable. The thickness of the base material layer is, for example, 50 to 50 μm, more preferably 10 to 30 μm. For the flexible film, for example, the total thickness of each layer is preferably 500 μm or less, and may be about 350 μm or about 200 μm.
　筒状部材と端面部材（天面部材、底面部材）を有する容器（筒状容器）において、筒状部材の端面（天面又は底面）の平面形状は、円形に限らず、楕円形、長円形、卵形、多角形等でもよい。平面形状の多角形としては、例えば三角形、四角形、五角形、六角形、七角形、八角形等の凸多角形、星形等の凹多角形が挙げられる。端面部材の平面形状及び筒状部材の水平断面形状は、端面（天面又は底面）の平面形状に応じて、適宜設定することができる。例えば、端面部材が多角形状の場合は、筒状部材も多角柱状となる。 In a container (cylindrical container) having a tubular member and an end face member (top member, bottom surface member), the planar shape of the end face (top surface or bottom surface) of the tubular member is not limited to a circular shape, but is oval or oval. , Oval, polygon, etc. Examples of the planar polygon include a convex polygon such as a triangle, a quadrangle, a pentagon, a hexagon, a heptacorn, and an octagon, and a concave polygon such as a star. The plane shape of the end face member and the horizontal cross-sectional shape of the tubular member can be appropriately set according to the plane shape of the end face (top surface or bottom surface). For example, when the end face member has a polygonal shape, the tubular member also has a polygonal columnar shape.
　筒状部材の端面が多角形の場合、軸方向は、両端面を構成する多角形の略中心（例えば重心）を結ぶ方向とすることができる。軸に交差する径方向は、端面に沿って端面の略中心を通る方向であればよく、例えば対向する二辺の中点を結ぶ方向、一頂点とそれに対向する辺の中点とを結ぶ方向、対角線方向（対向する二頂点を結ぶ方向）等が挙げられる。筒状部材の端面とは、各端面における端面部材の有無によらず、例えば、筒状部材の軸方向の両端部において、軸に垂直な平面のうち筒状部材に囲まれる内側の領域からなる仮想面である。 When the end face of the tubular member is polygonal, the axial direction can be the direction connecting the substantially centers (for example, the center of gravity) of the polygons constituting both end faces. The radial direction intersecting the axis may be a direction that passes through the substantially center of the end face along the end face, for example, a direction connecting the midpoints of two opposing sides, and a direction connecting one vertex and the midpoint of the opposite side. , Diagonal direction (direction connecting two opposing vertices) and the like. The end face of the tubular member is composed of, for example, an inner region of a plane perpendicular to the axis surrounded by the tubular member at both ends in the axial direction of the tubular member regardless of the presence or absence of the end face member on each end face. It is a virtual plane.

You may. When a joint portion is provided in the circumferential direction of the tubular member, it is preferable to superimpose and join the inner surface of one end edge and the outer surface of the other end edge because the joint portion does not easily protrude to the outer periphery. At the joint of the tubular members, the inner surfaces of both end edges or the outer surfaces may be opposed to each other and joined.
　筒状部材は天面と底面とが合同（同一形状及び同一寸法）である場合に限らず、例えば、天面が大で底面が小、又は、天面が小で底面が大となるようなテーパを有してもよい。天面と底面とが相似形でもよく、又は、互いに異種の形状としてもよい。円筒状の筒状部材は、略矩形状のフィルムの両端縁を接合して構成してもよい。略矩形状のフィルムにおいて対向する二辺を円弧状にすると、筒状部材を円錐状に構成することができる。 The tubular member is not limited to the case where the top surface and the bottom surface are congruent (same shape and the same dimensions), for example, the top surface is large and the bottom surface is small, or the top surface is small and the bottom surface is large. It may have a taper. The top surface and the bottom surface may have similar shapes, or may have different shapes from each other. The cylindrical member may be formed by joining both ends of a substantially rectangular film. By forming the two opposite sides of a substantially rectangular film into an arc shape, the tubular member can be formed into a conical shape.
　筒状部材の直径は、例えば、５～２５０ｍｍの範囲内で、１０～２００ｍｍの範囲内が好ましい。筒状部材が角筒状である場合の直径とは、互いに対向する頂点と頂点、辺と辺、又は頂点と辺との距離であり、これらが２以上ある場合は、最小値及び最大値が上記範囲内であることが好ましい。筒状部材の直径は、特に限定されないが、例えば、２０ｍｍ、５０ｍｍ、１００ｍｍ、１５０ｍｍ等でもよい。筒状部材及び底面部材は、天面部材と同様な積層体から構成されてもよく、又は、天面部材とは異なる構成でもよい。 The diameter of the tubular member is preferably in the range of 5 to 250 mm and preferably in the range of 10 to 200 mm. The diameter when the tubular member has a square tubular shape is the distance between the vertices and the vertices, the sides and the sides, or the vertices and the sides facing each other, and when these are two or more, the minimum value and the maximum value are It is preferably within the above range. The diameter of the tubular member is not particularly limited, but may be, for example, 20 mm, 50 mm, 100 mm, 150 mm, or the like. The tubular member and the bottom surface member may be composed of a laminated body similar to the top surface member, or may have a configuration different from that of the top surface member.
　容器に収容される内容物の性状は、液体、固体、粉体、粒体、これらの２種以上の混合物など任意である。内容物の種類としては、特に限定されず、飲料品、食料品、調味料、化粧品、医薬品、洗剤、接着剤、家庭用品、工業製品などが挙げられる。容器を構成する各部材には、酸素吸収機能、匂い吸収機能、非吸着機能など、１又は２以上の機能性を付与してもよい。筒状部材、天面部材、底面部材及び注出口は、それぞれ少なくとも１以上の印刷柄を有してもよい。容器を構成する各部材は、樹脂に限らず、紙、布、不織布、繊維などの異種材料を積層又は配合してもよい。 The properties of the contents contained in the container are arbitrary, such as liquid, solid, powder, granular material, and a mixture of two or more of these.

Each member constituting the container may be provided with one or more functionalities such as an oxygen absorption function, an odor absorption function, and a non-adsorption function. The tubular member, the top surface member, the bottom surface member, and the spout may each have at least one or more printed patterns. Each member constituting the container is not limited to resin, and different materials such as paper, cloth, non-woven fabric, and fiber may be laminated or blended.
　容器の使用時において、注出口を開封した状態で容器を置くと、通常は注出口が上向きとなることから、容器に注出口を設ける位置が天面部である。そのときの注出口の向きは鉛直上方に限らず、斜め上向きでもよい。内容物を注出するときは、注出口を横向き又は下向きとしてもよく、注出口が上向きのままストロー、ポンプ等で吸引してもよい。キャップ、栓等で注出口を密封した場合、例えば貯蔵、保管、展示等の目的で容器を置く際には、注出口の向きは限定されず、例えば注出口を横向き又は下向きとしてもよい。また、注出口にコック等を設けた場合は、容器の側面部又は底面部に注出口を設けて、注出口を横向き又は下向きとして容器を使用してもよい。容器に注出口を設ける数は限定されず、２以上としてもよい。注出口が内容物の注入、空気の流入等、内容物の注出以外の目的で使用されてもよい。 When using the container, if the container is placed with the spout opened, the spout usually faces upward, so the position where the spout is provided is the top surface. The direction of the spout at that time is not limited to vertically upward, and may be diagonally upward. When pouring out the contents, the spout may be oriented sideways or downward, and the spout may be sucked with a straw, a pump, or the like with the spout facing upward. When the spout is sealed with a cap, stopper, etc., for example, when the container is placed for the purpose of storage, storage, display, etc., the direction of the spout is not limited, and the spout may be oriented sideways or downward, for example. When a cock or the like is provided at the spout, the container may be used with the spout facing sideways or downward by providing the spout on the side surface or the bottom surface of the container. The number of spouts provided in the container is not limited, and may be two or more. The spout may be used for purposes other than pouring the contents, such as injecting the contents and inflowing air.
