Description
本発明は、コップ状紙成形容器等の開口部を有する紙成形体に関する。 The present invention relates to a paper molded body having an opening such as a cup-shaped paper molding container.
近年環境負荷の観点から循環型資源としての紙材を主体する紙成形体が注目され、密封性を高めて常温保存できる紙製密封容器が求められている。しかしながら、紙は展性がないため成形性に欠け、一部に絞り成形容器も実用化されているが、多くはブランクを貼り合わせ加工して容器を成形している。そのような紙成形容器は次のような理由により密封性に欠ける欠点がある。 In recent years, from the viewpoint of environmental load, a paper molded body mainly composed of a paper material as a recyclable resource has attracted attention, and a paper sealed container that can be stored at room temperature with improved sealing performance is required. However, since paper is not malleable, it lacks moldability, and some of the drawn containers have been put to practical use. However, many containers are formed by laminating blanks. Such a paper-molded container has a drawback of lacking sealing performance for the following reasons.
たとえば飲食用の紙成形体として代表的なコップ状紙成形体は、開口カール部にブランク両端縁の貼り合わせによる段差があり、胴部にも貼り合わせ部ができ、該貼り合わせ部の両端縁は紙端がコップ内側及び外側で露出している。
このようなコップ状紙成形体における内容物を充填し密封する場合、カール部の上面にシール蓋材をヒートシールしている。また、店頭販売等で充填して直ぐ消費される場合は、オーバーキャップを嵌着係合させて販売されている。蓋材をヒートシールする際は、蓋材の熱接着不良を防止するために通常カール部を平坦に潰してフランジ状にして接着面積の増大を図っている。このようなコップ状紙成形体は、直飲み用容器として使用されているが、前記のように開口端部に段差部があると口当たりに違和感があり、その上平坦に潰したフランジそのものが口あたりに違和感がある。また、胴部の貼り合せでは紙端縁が成形体の内外に露出するので、特に内側に位置する紙端縁は直接内容液と接触して吸湿してしまい、容器の耐水性を劣化させるという問題点がある。また、絞り成形体の場合、開口周縁のフランジ部にしわが発生するため、該フランジ面に蓋材をシールした場合に密封性を確保するのが困難であるという問題点がある。
For example, a typical cup-shaped paper molded body as a paper molded body for eating and drinking has a step due to bonding of both ends of the blank at the opening curl portion, and a bonding portion is also formed at the body portion. The paper edge is exposed inside and outside the cup.
When the contents in such a cup-shaped paper molded body are filled and sealed, a sealing lid material is heat-sealed on the upper surface of the curled portion. In addition, when the product is consumed immediately after being filled in a store or the like, it is sold with an overcap fitted. When heat-sealing the lid material, the curled portion is usually flattened to form a flange to prevent the lid material from being thermally bonded to increase the adhesion area. Such a cup-shaped paper molded product is used as a container for direct drinking. However, as described above, if there is a stepped portion at the opening end, the mouth feels uncomfortable, and the flatly crushed flange itself is the mouth. There is a sense of incongruity. In addition, since the paper edge is exposed inside and outside of the molded body when the body part is bonded, the paper edge located inside particularly directly contacts the content liquid and absorbs moisture, which deteriorates the water resistance of the container. There is a problem. Further, in the case of a drawn molded body, wrinkles are generated in the flange portion at the periphery of the opening, and thus there is a problem that it is difficult to ensure sealing performance when a lid member is sealed on the flange surface.
ブランクを貼り合わせ成形した紙成形体の上記問題点を解決する方法として、従来ブランクの対向する両端縁に基材シート上に積層された熱可塑性樹脂層からなる端縁延設片を設け、基材シートの紙部分が重ならないように、一方の端縁延設片が紙成形体の内側に、他方の端縁延設片が外側にくるように両端部を貼り合わせ、各々端縁延設片同士を熱圧着するようにするものが提案されている（特許文献１参照）。また、他の方法として、内側となる側縁部を端辺に行くにしたがって薄くなるように削り取り、外側となる側縁部を貼り合わせて胴部貼り合わせ部及びカール貼り合わせ部を形成することによって、貼り合わせ部の段差を小さくするようにしたものが提案されている（特許文献２参照）。さらに他の手段として、開口部に別途成形した樹脂製補強リングを溶着することにより、開口部のカール部における段差をなくして密封性及び口当たり性を良くするようにしたものも提案されている（特許文献３参照）。 As a method of solving the above-mentioned problems of the paper molded body in which a blank is bonded and molded, an edge extending piece made of a thermoplastic resin layer laminated on a base sheet is provided on both opposite edges of a conventional blank, Adhere both ends so that the paper part of the material sheet does not overlap, with one edge extending piece inside the paper molded body and the other edge extending piece outside. There has been proposed a technique in which pieces are thermocompression bonded (see Patent Document 1). Also, as another method, the inner side edge portion is scraped so as to become thinner toward the end side, and the outer side edge portion is bonded to form a body bonding portion and a curl bonding portion. Has been proposed in which the level difference of the bonded portion is reduced (see Patent Document 2). As another means, a resin reinforcing ring formed separately in the opening is welded to eliminate a step in the curled portion of the opening so as to improve the sealing performance and mouth feel ( (See Patent Document 3).
しかしながら、前記特許文献１、２に記載されているように、貼り合わせ端部をラミネート端部で形成すること、或いは紙端縁を薄く加工して貼り合わせ段差を小さくするようにすることは、加工難易度が高く不安定であり、かつ製造工程が複雑になるという問題点があり、製造工程の高速化、効率化が難しい。また、別部材の開口部補強樹脂リングを紙成形体に融着することは、材料コストが高くなると共に別途樹脂リング成形工程及び溶着工程が必要となるため、製造コスト高になる等の問題点がある。
そこで、本発明は、紙成形体における上記問題点を複雑な工程を経ずに簡易に解決でき、開口部を有する紙成形体の密封性及び貼り合わせ部や皺の発生に起因する上記問題点を解消した紙成形体を提供することを目的するものである。
However, as described in Patent Documents 1 and 2, forming the bonding end portion with the laminate end portion, or processing the paper edge thinly to reduce the bonding step, There is a problem that the processing difficulty is high and unstable, and the manufacturing process is complicated, and it is difficult to increase the speed and efficiency of the manufacturing process. Also, fusing the opening-reinforced resin ring of another member to the paper molded body increases the material cost and requires a separate resin ring molding step and a welding step, resulting in problems such as high manufacturing costs. There is.
Therefore, the present invention can easily solve the above-mentioned problems in the paper molded body without going through a complicated process, and the above-mentioned problems caused by the sealing property of the paper molded body having an opening and the occurrence of bonded portions and wrinkles. An object of the present invention is to provide a paper molded body that eliminates the above-mentioned problem.
上記問題点を解決する本発明の紙成形体は、開口部を有し、局所部に合成樹脂粉体を主体とする材料の溶射による樹脂盛りがなされているコップ状紙成形体であって、前記局所部が前記コップ状紙成形体の少なくとも開口部周縁の開口カール部における貼り合わせ段差部であり、前記樹脂盛りによって前記段差部を埋めていることを特徴とするものである。
また本発明の紙成形体は、前記局所部がさらに紙成形体の胴部の貼り合わせ段差部であり、該段差部への樹脂盛りによって、前記貼り合わせ部の紙端縁を樹脂被覆するように構成することができる。
また、本発明の紙成形体は、前記樹脂盛りが、熱接着性樹脂粉末を溶射して形成された被膜厚さ０．３ｍｍ以下であるように構成することができる。
Molded paper product of the present invention to solve the above problems, have a opening, a cup-shaped sheet molded resin prime have been made by thermal spraying of the material mainly composed of synthetic resin powder to the local unit, The local portion is a bonding stepped portion at an opening curled portion at least at the periphery of the opening of the cup-shaped paper molded body, and the stepped portion is filled with the resin piling .
Further , in the paper molded body of the present invention, the local portion is further a bonding stepped portion of the body portion of the paper molded body, and the paper edge of the bonding portion is resin-coated with a resin pile on the stepped portion. Can be configured.
Moreover, the paper molded body of this invention can be comprised so that the said film thickness may be 0.3 mm or less of the film thickness formed by spraying the thermoadhesive resin powder.
本発明によれば、単に紙成形体の局所に樹脂盛りを施すことにより、開口部を有する紙成形体の貼り合わせ部や皺の発生に起因する問題点をブランク基材に特別な加工を施すことなく容易にかつ安価なコストで解決でき、密封性に優れた紙成形体を得ることができる。
また、本発明によれば、コップ状紙成形体の少なくとも開口周縁の開口カール部における貼り合わせ段差部に少量の樹脂が正確に樹脂盛りされているので、該容器から内容物を直飲みする場合の口当たりを良くすると共に、蓋材をヒートシールする際の該段差部でのシール性が向上し密封性を高めることができ、紙成形体を内容物が常温保存できる密封容器への適用性を高めることができる。また該容器にオーバーキャップを被せて密封する際の、前記段差部からの漏洩を効果的に防ぐことができる。
さらに、本発明を紙成形体の貼り合わせ部等の露出紙端縁に適用して、該露出紙端縁を効果的に樹脂被覆することができ、露出紙端縁から内容液等の吸湿を防止して耐水性を高めることができる。

According to the present invention, the blank base material is specially processed to solve the problems caused by the bonded portion of the paper molded body having openings and the occurrence of wrinkles simply by applying a resin pile locally to the paper molded body. Therefore, it is possible to obtain a paper molded body that can be easily solved at low cost and has excellent sealing properties.
Further , according to the present invention , since a small amount of resin is accurately placed on the bonding stepped portion at the opening curl portion at least at the opening periphery of the cup-shaped paper molded body, the contents can be directly drunk from the container. In addition to improving the mouthfeel of the lid, the sealing performance at the stepped portion when the lid material is heat-sealed can be improved and the sealing performance can be improved, and the applicability to a sealed container in which the contents of the paper molded body can be stored at room temperature is improved. Can be increased. In addition, leakage from the step portion when the container is sealed with an overcap can be effectively prevented.
Furthermore, the present invention can be applied to an exposed paper edge such as a bonded portion of a paper molded body to effectively coat the exposed paper edge with a resin, and absorb moisture such as content liquid from the exposed paper edge. Water resistance can be increased by preventing.

以下、本発明に係る紙成形容器の実施形態を図面を基に詳細に説明する。
図１は、本発明の実施形態に係る紙成形体としてのコップ状容器を示す。該コップ状容器１は、胴部２となる扇形状のブランクの両端縁を貼り合わせて接着して円錐状に成形し、その上端部をカール成形して開口端部とし、下端部を内側に折り返して折り返し片を形成し、その間に断面コ字状に絞り成形した底板の環状屈曲部を圧着した構造となっており、開口カール部３には図１（ｂ）に拡大して示すようにブランク両端縁の貼り合わせによる段差４ができている。また、胴部には貼り合わせ部５ができ、該貼り合わせ部の両端縁には紙端がコップ内側及び外側で露出している。以上の構造は、従来周知のコップ状紙成形容器と同様である。
Hereinafter, embodiments of a paper molding container according to the present invention will be described in detail with reference to the drawings.
FIG. 1 shows a cup-shaped container as a paper molded body according to an embodiment of the present invention. The cup-shaped container 1 is formed by concatenating and bonding both end edges of a fan-shaped blank serving as the body portion 2 to form a conical shape, curling the upper end portion to form an open end portion, and the lower end portion to the inside. A folded piece is formed by folding, and an annular bent portion of a bottom plate drawn into a U-shaped cross section is pressed between the folded pieces, and the opening curled portion 3 is enlarged as shown in FIG. A step 4 is formed by pasting both edges of the blank. Further, a bonding portion 5 is formed on the body portion, and paper edges are exposed at both ends of the bonding portion on the inner side and the outer side of the cup. The above structure is the same as that of a conventionally known cup-shaped paper molding container.
このようなコップ状紙成形容器において、前述した開口部周縁の開口カール部３における段差部４による密封不良及び直飲容器としての口当たり不良を解消するために、本発明においては、段差部に少量の合成樹脂を溶射して樹脂盛り８を行って、段差を樹脂によって埋めるようにした。
コップ状紙成形容器のカール部の段差部４という狭い領域に的確に樹脂盛りをすることは困難であるが、本実施形態では、図３に模式的に示す樹脂溶射装置により、粉体樹脂を間欠的に溶射することにより、カール部の段差部４に良好に樹脂盛りをすることができ、上記問題点を原紙端縁自体を特別な加工を施すことなく、簡単な方法により解決することができた。
In such a cup-shaped paper molding container, in order to eliminate the above-mentioned poor sealing due to the stepped portion 4 in the opening curled portion 3 at the periphery of the opening and the mouthfeel as a direct drinking container, The synthetic resin was thermally sprayed to perform resin filling 8 so that the step was filled with resin.
Although it is difficult to accurately deposit the resin in a narrow region called the stepped portion 4 of the curled portion of the cup-shaped paper molding container, in this embodiment, the resin resin spraying apparatus schematically shown in FIG. By spraying intermittently, the stepped portion 4 of the curled portion can be satisfactorily filled with resin, and the above problems can be solved by a simple method without special processing of the edge of the base paper itself. did it.
また、本実施形態では、図１（ｃ）に拡大して示すように、紙成形容器の胴部貼り合わせ部５の特にコップ内面側の紙端縁６に沿って連続した樹脂盛り９を行って、内面側に露出している紙端縁６を樹脂被覆した。それにより、紙端縁６が内容液に直接接触することがなくなり、容器の耐湿性を向上させることができた。なお、本実施形態では貼り合わせ部の内側紙端縁のみを樹脂被覆したが、外側も同様に樹脂被覆することが望ましい。 Further, in this embodiment, as shown in an enlarged view in FIG. 1 (c), a continuous resin fill 9 is performed along the paper edge 6 on the inner surface side of the cup portion of the body portion bonding portion 5 of the paper molding container. The paper edge 6 exposed on the inner surface side was coated with resin. As a result, the paper edge 6 is not in direct contact with the content liquid, and the moisture resistance of the container can be improved. In the present embodiment, only the inner paper edge of the bonded portion is resin-coated, but it is desirable that the outer side be similarly resin-coated.
図２は、本発明の他の実施形態を示し、本実施形態では絞り成形容器１０のフランジ面１２に、絞り成形により生じたフランジ面の皺１４を覆うようにフランジ全周に樹脂盛り１３（図２では樹脂盛りの途中まで行った状態を示している）を行い、蓋材をヒートシール時に該樹脂が融着して皺を埋めて、蓋材が完全に融着して密封性を高めるようにした。 FIG. 2 shows another embodiment of the present invention. In this embodiment, the flange surface 12 of the draw-molded container 10 has a resin pile 13 ( FIG. 2 shows a state where the resin is partway filled), and when the lid material is heat-sealed, the resin is fused to fill the flaws, and the lid material is completely fused to improve the sealing performance. I did it.
以上のように紙成形容器の局所の狭い領域に少量の樹脂盛りを行うのは樹脂の糸引きがあり、所定の局所のみに短時間に効率よく樹脂盛りすることは困難で樹脂のムダが生じるが、本実施形態では次のような樹脂被覆装置を使用して、粉体樹脂を間欠的に溶射することによって、糸引き現象が生じることなく所定の小領域に樹脂被覆を的確にすることができ、使用材料を最小限にすることができた。 As described above, a small amount of resin piling in a narrow local area of a paper-molded container involves resin stringing, and it is difficult to pour resin only in a predetermined local area in a short time, resulting in resin waste. However, in this embodiment, by using the following resin coating apparatus and spraying the powder resin intermittently, the resin coating can be accurately applied to a predetermined small area without causing the stringing phenomenon. It was possible to minimize the material used.
図３は、被覆装置３０の実施形態を示し、合成樹脂粉体が供給されるタンク３１、該タンクの下端と連通した溶射ノズル３２、タンク３１の下端開口部と溶射ノズル３２との間に設けられた定量切り出しシャッター装置３５とを備え、タンク３１から定量の粉体を定量切り出しシャッター装置３５で切り出して、前記溶射ノズルから溶射するようにしてなるものである。 FIG. 3 shows an embodiment of the coating apparatus 30, a tank 31 to which synthetic resin powder is supplied, a thermal spray nozzle 32 communicating with the lower end of the tank, and a lower end opening of the tank 31 and the thermal spray nozzle 32. The fixed quantity cutout shutter device 35 is provided, and a fixed quantity of powder is cut out from the tank 31 by the fixed quantity cutout shutter device 35 and sprayed from the spray nozzle.
定量切り出しシャッター装置３５は、タンク３１の下端開口部を横切る回転体３６からなり、該回転体３６にタンク３１の下端開口部に面し、頂部が回転体３６の略中心軸線に至るような円錐状窪みの計量室３７が設けられている。そして、回転体３６の一端は間欠回転駆動手段（図示していない）に連結され、かつ中心軸線に沿って一端が加圧ガス源に接続した流路４２を有し、該流路が計量室３７の頂部に形成したガス供給口３８に連通している。流路４２にはコンプレッサー等の圧縮空気供給源に連結された供給管路４３が連結され、該供給管路に設けた電磁バルブ４４によって、加圧ガスの計量室内への送給タイミングを制御する。回転体３６は間欠的に半回転し、定量室が粉体計量位置と溶射ノズルへの圧送位置に交互に位置するように、制御される。 The fixed quantity cut-out shutter device 35 includes a rotating body 36 that crosses the lower end opening of the tank 31, faces the lower end opening of the tank 31 to the rotating body 36, and has a cone whose top reaches the substantially central axis of the rotating body 36. A measuring chamber 37 with a hollow shape is provided. One end of the rotator 36 is connected to intermittent rotation driving means (not shown), and has a channel 42 having one end connected to a pressurized gas source along the central axis, and the channel is a measuring chamber. It communicates with a gas supply port 38 formed at the top of 37. A supply pipe 43 connected to a compressed air supply source such as a compressor is connected to the flow path 42, and an electromagnetic valve 44 provided in the supply pipe controls the timing of feeding pressurized gas into the measurement chamber. . The rotator 36 is intermittently half-rotated and controlled so that the metering chamber is alternately positioned at the powder metering position and the pressure feeding position to the spray nozzle.
上記装置において、図３（ａ）の状態でタンク３１内に粉体樹脂が供給されており、この状態で定量切出しシャッター装置３５の計量室３７内に計量室の容積分の粉末樹脂が自動的に充填され、回転体３６が１８０゜回転することにより(図３（ｂ）)、計量室３７は反転して溶射ノズル３２の導入流路に面し、同時にバルブ４４が開いて加圧エアが反転した計量室にガス供給口３８を介して吹き込まれ、計量室内の定量の樹脂粉末が溶射ノズルの噴射流路を流れる加熱ガスと合流して対象物の極所領域に溶射される(図３（ｃ）)。
上記操作を繰り返して少量の粉体樹脂を、対象物である紙成形容器が停止している状態で、同一箇所に間欠的に複数回に渡って溶射することによって、樹脂の糸引きがなくごく狭い範囲である段差部に確実に所定量の樹脂盛りを形成することができる。
なお、粉体樹脂が溶射される領域は、あらかじめ樹脂の溶融温度以下に予備加熱しておくのが望ましい。本発明の方法によれば、少量の樹脂を間欠的に噴射するので、溶射樹脂が部分的に溶融した状態であって対象物表面で溶融して融着することができ、融着不良を起こすことがない。
加熱ガスとしては、熱風が望ましく、コンプレッサー等の空気供給源に連結された熱風発生器４０により電気的或いはガス燃焼等の加熱手段で所定温度に加熱されて溶射ノズルに供給される。
In the above apparatus, the powder resin is supplied into the tank 31 in the state of FIG. 3A, and in this state, the powder resin corresponding to the volume of the measuring chamber is automatically loaded into the measuring chamber 37 of the quantitative cutout shutter device 35. When the rotating body 36 is rotated 180 ° (FIG. 3B), the measuring chamber 37 is reversed to face the introduction flow path of the thermal spray nozzle 32, and at the same time, the valve 44 is opened and pressurized air is supplied. The metered chamber is blown into the inverted measuring chamber through the gas supply port 38, and a certain amount of the resin powder in the measuring chamber joins with the heated gas flowing through the spraying channel of the spray nozzle, and is sprayed onto the extreme region of the object (FIG. 3). (C)).
By repeating the above operation and spraying a small amount of powder resin intermittently to the same location multiple times with the paper molding container as the target stopped, there is no resin stringing. A predetermined amount of resin can be reliably formed on the stepped portion which is a narrow range.
In addition, it is desirable that the region where the powder resin is sprayed is preliminarily heated below the melting temperature of the resin. According to the method of the present invention, since a small amount of resin is intermittently injected, the sprayed resin is partially melted and can be melted and fused on the surface of the object, resulting in poor fusion. There is nothing.
The heated gas is preferably hot air, and is heated to a predetermined temperature by heating means such as electric or gas combustion by a hot air generator 40 connected to an air supply source such as a compressor and supplied to the spray nozzle.
実施例１：（段差部への樹脂盛り）
コップ状容器１の開口カール部３の段差部４近傍に前記装置により次の条件で樹脂を溶射した。
粉体樹脂： 平均粒径１２０μｍの低密度ポリエチレン粉体
１回の粉体噴射量： 約２５ｍｇ
溶射ノズルと溶射対象面間の距離： １０ｍｍ
ノズル出口熱風温度： ３２０℃
予備加熱： 噴射前遅延１．５ｓ
備考： 熱風発生器による再加熱を実施
その結果、段差部４を覆うように図４に示すように被覆膜厚０．３ｍｍの樹脂盛り８を良好に形成することができた。
このように、段差部に樹脂盛りをすることによって、蓋材をヒートシールする際に該樹脂が溶融しカール部を圧潰しなくても蓋材との溶着性がより高まり、密封性が向上すると共に直飲時の違和感をなくすことができた。また、オーバーキャップの場合も、カール部の段差部がなくなるため、そこからの洩れを防止できる。
Example 1: (resin pile on a step part)
Resin was sprayed in the vicinity of the stepped portion 4 of the opening curled portion 3 of the cup-shaped container 1 by the above apparatus under the following conditions.
Powder resin: Low density polyethylene powder with an average particle size of 120 μm Single powder injection amount: Approximately 25 mg
Distance between spray nozzle and spray target surface: 10mm
Nozzle outlet hot air temperature: 320 ° C
Preheating: Delay before injection 1.5s
Remarks: Reheating with a hot air generator As a result, as shown in FIG. 4, a resin pile 8 having a coating film thickness of 0.3 mm could be satisfactorily formed so as to cover the stepped portion 4.
In this way, by depositing the resin on the stepped portion, the resin melts when the lid material is heat-sealed, so that the weldability with the lid material is further increased without crushing the curled portion, and the sealing performance is improved. And I was able to eliminate the uncomfortable feeling when drinking directly. Also, in the case of an overcap, the step portion of the curled portion is eliminated, so that leakage from the curled portion can be prevented.
本発明は、紙成形容器における局所領域に確実にかつ効率よく樹脂盛りをすることによって、簡単な構成で紙成形容器の密封性の問題点を解決でき、安価な構成で紙成形容器の常温流通への適用可能性を高めることができ、産業上の利用可能性が高い。 The present invention can solve the problem of the sealing property of the paper molding container with a simple configuration by reliably and efficiently depositing the resin in a local region in the paper molding container, and the room temperature distribution of the paper molding container with an inexpensive configuration. The applicability to the industry can be increased, and the industrial applicability is high.
