Description

本発明は、三角おにぎりをフィルム包装した包装三角おにぎりに関するものである。 The present invention relates to a packaged triangular rice ball in which triangular rice balls are packaged .

コンビニエンスストアで販売されている「包装三角おにぎり」の包装形態には、図１１に示す如く、包装シート(１)によって、三角おにぎり(５)をその形状に沿わせて包んだもの(特許文献１)と、図１２に示す如く、包装袋(６)におにぎり(５)を収容したものとがある。
前者の包装形態は、図１３、図１４に示す如く、外フィルム(２)と内フィルム(３)との間にシート状海苔(４)を挟んで形成した包装シート(１)を使用することにより、シート状海苔(４)をおにぎり(５)と外気の両方から遮断でき、該海苔を長時間に亘って乾燥状態に保って風味や食感を損なわない。又、外フィルム(２)にカットテープ(22)を施して分断可能部(21)が形成されており、おにぎりの包装を簡単に解くことができ、包装を解くと自然にシート状海苔(４)がおにぎりに被さる様になっており、食するのに便利である。 In the packaging form of “wrapping triangular rice balls” sold at convenience stores, as shown in FIG. 11, a triangular sheet (5) is wrapped along the shape by a packaging sheet (1) (Patent Document 1). ) And rice balls (5) stored in packaging bags (6), as shown in FIG.
The former packaging form uses a packaging sheet (1) formed by sandwiching a sheet-like seaweed (4) between an outer film (2) and an inner film (3) as shown in FIGS. Thus, the sheet-like nori (4) can be shielded from both the rice balls (5) and the outside air, and the nori is kept dry for a long time without losing the flavor or texture. In addition, the cut-off tape (22) is applied to the outer film (2) to form a severable part (21), which makes it easy to unwrap the rice balls. ) Is covered with rice balls and is convenient for eating.

図１２の後者の包装形態は、近時の高級志向から生まれたもので、おにぎりの形状がそのまま包装形態に表れる前者に比べて、おにぎりを大きく見せる効果もある。
但し、包装袋(６)は１枚もののシートで形成されており、おにぎり(５)は直接にシート状海苔が巻かれた状態で該包装袋(６)に収容されるため、おにぎりを食するまでに該海苔は湿気てしまい、海苔の風味や食感が損なわれる。
更に後者は、包装を解く際に、袋の開口封止部(61)に施されたＶ字状の切込み(62)を挟んで、袋の封止部(61)に両手の親指ｆ１、ｆ２が当たる様に袋を支持し、切込み(62)から包装袋(６)を裂く。このとき、おにぎり(５)を手で保持しておくことが出来ないため、包装袋(６)が２つに裂けた途端、袋からおにぎり(５)が落下してしまうことがある。落下したおにぎり(５)は原形を留めないほどに崩れて、食することが出来なくなる。 The latter packaging form of FIG. 12 was born from a recent luxury orientation, and has the effect of making the rice balls look larger than the former, where the shape of the rice balls appears directly in the packaging form.
However, the packaging bag (6) is formed of a single sheet, and the rice ball (5) is stored in the packaging bag (6) in a state where the sheet-like seaweed is wound directly, so the rice ball is eaten. By the time, the seaweed becomes wet, and the flavor and texture of the seaweed are impaired.
Furthermore, in the latter case, when unpacking, the thumbs f1 and f2 of both hands are put on the sealing part (61) of the bag with the V-shaped cut (62) made on the opening sealing part (61) of the bag being sandwiched. Support the bag so that it hits and tear the packaging bag (6) from the cut (62). At this time, since the rice ball (5) cannot be held by hand, the rice ball (5) may fall from the bag as soon as the packaging bag (6) is split into two. The dropped rice ball (5) collapses beyond its original shape and cannot be eaten.

そこで出願人は、図１３、図１４に示す包装シートで、図１２に示す様な包装形態を実施することを試みた。これは包装シート(１)を、図６ｅに示す如く、内フィルムを内側にしておにぎりを包む様にして袋状に折り、図６ｆに示す如く、該包装シートの長手方向に沿う縁部どうしを折り重ねて襠(17)を形成し、折り重なり部を溶着(16)することにより、おにぎりを収容した袋(10)を形成し、該袋(10)の開口(10a)を溶着等によって封止するのである。
ところが、包装状態で７、８時間以上経過すると、シート状海苔が湿気てしまうことが分かった。これは、おにぎりが余裕のある状態に袋に収容されているため、包装状態において、図１５に示す如く、内フィルム(３)を構成する２枚のフイルム片(31)(31)の重なり部が部分的に口を開いて、おにぎりからの湿気がシート状海苔を徐々に湿気させるからである。 Therefore, the applicant tried to implement a packaging form as shown in FIG. 12 with the packaging sheets shown in FIGS. As shown in FIG. 6e, the packaging sheet (1) is folded into a bag shape with the inner film inside and wrapped with rice balls, as shown in FIG. 6f, and the edges along the longitudinal direction of the packaging sheet as shown in FIG. 6f. A bag (10) containing rice balls is formed by folding and forming a ridge (17) and welding the folded portion (16), and the opening (10a) of the bag (10) is sealed by welding or the like. It stops.
However, it has been found that the sheet-like seaweed becomes damp after 7 or 8 hours have passed in the packaged state. This is because the rice ball is accommodated in a bag in a state where a margin, in the packaging state, as shown in FIG. 15, the inner film (3) two film pieces constituting the (31) overlapping part of (31) There open partially mouth, moisture from the rice balls is because is gradually moisture layer sheet.

［包装すべき三角おにぎり］
図６に示す如く、実施例の三角おにぎり(５)は、一辺が７cm前後、厚み３cm前記の大きさである。該おにぎりは、かやくご飯の塊、白米の塊等であり、内部に具が入っていても可い。 [ Triangle rice balls to be wrapped]
As shown in FIG. 6, the triangular rice ball of the embodiment (5), one side 7cm longitudinal, the magnitude of thickness 3cm said. The onigiri is a piece of rice, a piece of white rice, etc., and it may be filled with ingredients.

［包装袋］
上記三角おにぎり(５)を収容する包装袋は、図１乃至図３に示す、長さ約２６cm、幅約１６cmの長方形の包装シート(１)によって形成される。
包装シート(１)は、透明外フィルム(２)と半透明の内フィルム(３)との間に長方形のシート状食品(40)を挟み、外フィルム(２)と内フィルム(３)の外周部を溶着(12)(14)(15)して形成される。
シート状食品(40)は、実施例ではシート状海苔(４)である。シート状海苔(４)は、長さ約１８cm、幅約９cmの長方形であって、前記おにぎり(５)の底面及び両三角面に少し余裕のある状態に被さる程度の大きさである。シート状海苔(４)は包装シートの中央部に位置している。 [Packaging bag]
The packaging bag for accommodating the triangular rice ball (5) is formed by a rectangular packaging sheet (1) having a length of about 26 cm and a width of about 16 cm as shown in FIGS.
The packaging sheet (1) has a rectangular sheet-like food (40) sandwiched between a transparent outer film (2) and a translucent inner film (3), and the outer periphery of the outer film (2) and the inner film (3). The part is formed by welding (12) (14) (15).
The sheet-like food (40) is a sheet-like seaweed (4) in the examples. The sheet-like seaweed (4) is a rectangle having a length of about 18 cm and a width of about 9 cm, and is large enough to cover the bottom surface and both triangular surfaces of the rice ball (5). Sheet-like seaweed (4) is located in the center of the packaging sheet.

外フィルム(２)は、幅方向の中央部に、該フィルムを全長に亘って長さ方向に裂くことのできる分断可能部(21)を有している。
実施例の分断可能部(21)は、外フィルム(２)を長手方向に裂け易い方向性フィルムとし、該フィルムにカットテープ(22)を施し、更に外フィルム(２)の端部に切込み(23)(23)を施して形成される。
カットテープ(22)は、煙草の箱を覆っているフィルム包装を解く際に実施されて公知のものであって、細帯テープをフィルムに接着し、該細幅テープの一端を引っ張るとフィルムをテープ幅で裂くことができる。
実施例の場合、外フィルムの長手方向の全長に亘って、２本のカットテープ(22)(22)を互いに接近状態で平行に貼着し、外フィルム(２)の一端にて両カットテープ(22)(22)の外側に切込み(23)(23)を施している。
外フィルム(２)の切込み側の端部にてカットテープ間を摘んで、反対側端部へ向かって引っ張ると、切込み(22)(22)間の幅で外フィルム(２)を帯状に裂くことができる。 The outer film (2) has a separable portion (21) at the center in the width direction that can split the film in the length direction over the entire length.
The severable portion (21) of the example is a directional film that easily tears the outer film (2) in the longitudinal direction, and a cut tape (22) is applied to the film, and further cut into the end of the outer film (2) ( 23) It is formed by applying (23).
The cut tape (22) is known when unwrapping the film wrapping covering the cigarette box.When the strip tape is adhered to the film and one end of the narrow tape is pulled, the film is removed. Can be torn with tape width.
In the case of the examples, the two cut tapes (22) and (22) are stuck in parallel with each other over the entire length in the longitudinal direction of the outer film, and both cut tapes are attached to one end of the outer film (2). (22) Cuts (23) and (23) are made on the outside of (22).
When the end of the outer film (2) is cut between the cut tapes and pulled toward the opposite end, the outer film (2) is torn into a strip with the width between the cuts (22) and (22). be able to.

内フィルム(３)は、同じ形状の長方形の２枚のフィルム片(31)(31)を、互いの長手方向に沿う内側縁を１０〜２０mm程度の重なり幅で重ねて形成される。
上記内フィルム(３)の２枚のフィルム片(31)(31)は、互いの重なり部(32)が外フィルム(２)の分断可能部(21)に沿う平行な２本の線状接合部(34)(34)によって接合され、両フィルム片(31)(31)は、２本の線状接合部(34)(34)の間にて、夫々該線状接合部に沿う方向に分断可能な分断可能部(35)(35)を形成している点である。 The inner film (3) is formed by stacking two rectangular film pieces (31) and (31) having the same shape and overlapping the inner edges along the longitudinal direction with an overlapping width of about 10 to 20 mm.
The two film pieces (31) and (31) of the inner film (3) are two linear joints in which the overlapping part (32) is parallel to the severable part (21) of the outer film (2). joined by parts (34) (34), both the film strip (31) (31), at between two linear junction (34) (34), in the direction along the respective said linear joints It is the point which forms the part (35) (35) which can be divided and can be divided.

実施例の線状接合部(34)は、フィルム片(31)(31)の重なり部(32)において、互いに接触する面の内、少なくとも一方の面に予め加圧によって相手フィルム片に接着する作用のあるコーティング層を施し、細幅の回転ローラ(図示せず)によって、重なり部(32)を、連続した線状に加圧することによりフィルム片(31)(31)を接合している。
尚、線状接合部(34)は、フィルム接合では常套手段である熱溶着による接合方法を採用できるのは勿論である。後記する第２、第３実施例の線状接合部(34)も熱溶着で実施可能である。 In the overlapping portion (32) of the film pieces (31) and (31), the linear joint portion (34) of the example is adhered to the counterpart film piece by pre-pressing at least one of the surfaces in contact with each other. A film layer (31) (31) is joined by applying a coating layer having an action and pressurizing the overlapping portion (32) into a continuous line by a narrow rotation roller (not shown).
Of course, the linear joining portion (34) can employ a joining method by heat welding, which is a conventional means in film joining. The linear joint portions (34) of the second and third embodiments described later can also be implemented by heat welding.

実施例の内フィルム(３)の分断可能部(35)(35)は、フィルム片(31)の表裏に貫通する断続的な切込み(36)を一直線上に施したものである。
両フィルム片(31)(31)の断続的な切込み(36)(36)は、ずれて重なっていない。これは、断続的な切込み(36)に相手フィルム片(31)が被さって、後記する包装状態の三角おにぎり(５)の湿気が、該断続的な切込み(36)(36)を通って内フィルム(３)と外フィルム(２)との間のシート状海苔(４)に可及的に届き難くするためである。 The severable portion (35) (35) of the inner film (3) in the example is formed by intermittently cutting (36) penetrating through the front and back of the film piece (31) on a straight line.
Intermittent cuts (36) and (36) of both film pieces (31) and (31) are shifted and do not overlap. This is because the intermittent notch (36) is covered with the counterpart film piece (31), and the moisture of the triangular rice ball (5) in the packaged state described later passes through the intermittent notches (36) and (36). This is to make it as difficult as possible to reach the sheet-like seaweed (4) between the film (3) and the outer film (2).

外フィルム(２)と内フィルム(３)の外周部の溶着を詳述すると、図１に示す如く、包装シート(１)の長手方向に沿う両側縁が太線状に断続的に溶着され、更に該太溶着線(12)から内側に１cm程度離して内側太溶着線(14)が包装シート(１)の全長に亘って施されている。包装シート(１)の両端には、後記する外フィルム(２)の分断可能部(21)を挟んで細溶着線(15)(15)が施されている。
包装シート(１)の長手方向に沿う両側縁に夫々内外に溶着線(12)(14)を設けたのは、包装シート(１)の長手方向に沿う両側縁は、後記の如く、該包装シート(１)を袋に折る際に、袋の襠部となる部分であって、仮に内外の溶着線(12)(14)の間も溶着してしまうと、その部分が硬くなり過ぎて襠を折る際に上手く折れないからである。
外側の太溶着線(12)に等間隔に未溶着部(13)を設けたのは、上記理由により包装シートの長手方向に沿う側縁を出来るだけ軟質にするためである。
外側の太溶着線(12)を省略することは、外フィルム(２)と内フィルム(３)の側縁が開いてしまって、後記袋折りの作業がし難くなる。 The welding of the outer peripheral part of the outer film (2) and the inner film (3) will be described in detail. As shown in FIG. 1, both side edges along the longitudinal direction of the packaging sheet (1) are intermittently welded in a thick line. An inner thick weld line (14) is provided over the entire length of the packaging sheet (1) at a distance of about 1 cm from the thick weld line (12). At both ends of the wrapping sheet (1), below which the outer film (2) of the division can portion (21) interposed therebetween fine weld line (15) (15) is applied.
The welding lines (12) and (14) are provided on both side edges along the longitudinal direction of the packaging sheet (1) inside and outside, respectively. The both side edges along the longitudinal direction of the packaging sheet (1) When the sheet (1) is folded into a bag, it is the part of the bag that becomes the heel of the bag, and if it is welded between the inner and outer welding lines (12) and (14), the part becomes too hard and the This is because it does not fold well when folding.
It was equal intervals in the non-welded portion on the outside of thick weld line (12) to (13) provided, in order to soft as possible side edges along the longitudinal direction of the package sheet for the aforementioned reason.
Omitting the outer thick welding line (12) opens the side edges of the outer film (2) and the inner film (3), making it difficult to carry out bag folding described later.

［おにぎりの包装手順］
図６ａに示す如く、外フィルム(２)を上側、内フィルム(３)を下側にして水平状態で待機している包装シート(１)の一端側に、横向き姿勢のおにぎり(５)を突き上げて、おにぎり(５)の三角上面に包装シート(１)を被せる。このとき、図６ｂに示す如く、包装シート(１)の幅中心がおにぎり(５)の幅中心に揃い、おにぎり底縁が包装シート(１)の長さ中心からおにぎりの厚みの１／２ずれた位置となる様に、包装シート(１)をおにぎり(５)に被せ、包装シートの他端側は垂下させる。
図６ｃに示す如く、包装シート(１)の垂下した部分をおにぎり(５)の三角下面に被さる様に折り畳む。これによって、略Ｕ字状に屈曲して両端の位置が揃った包装シートにおにぎり(５)が挟まれた状態となる。
図６ｄに示す如く、おにぎり(５)からはみ出た包装シート(１)の両耳部の中央部を内側に折り込む。
図６ｅに示す如く、包装シート(１)の上側の耳部(11a)を下向きに折り畳み、次に図６ｆに示す如く、下側の耳部(11b)を上向きに折り畳んで、耳部(11a)(11b)を折り重ねて溶着(16)して襠部(17)を形成し、一端が開口(10a)した四角形の袋(10)を形成する。
図６ｇに示す如く、袋開口(10a)を溶着して封止部を形成する。該封止部は、図７ａに示す如く、袋開口縁を外フィルム(２)の分断可能部(21)を挟んで太線状に溶し、更に該溶着太線(19)(19)より少し内側を細線(18)状に溶着している。該溶着細線(18)は、外フィルム(２)の分断可能部(21)の分断に支障のない程度に弱く溶着されている。 [Packaging procedure for rice balls]
As shown in FIG. 6a, a rice ball (5) in a horizontal position is pushed up to one end of the packaging sheet (1) waiting in a horizontal state with the outer film (2) on the upper side and the inner film (3) on the lower side. Put the packaging sheet (1) on the triangular upper surface of the rice ball (5). At this time, as shown in FIG. 6b, the width center of the packaging sheet (1) is aligned with the width center of the rice ball (5), and the bottom edge of the rice ball is shifted from the center of the length of the packaging sheet (1) by 1/2 of the thickness of the rice ball. The packaging sheet (1) is placed on the rice ball (5) so that the other end of the packaging sheet is suspended.
As shown in FIG. 6c, the hanging part of the packaging sheet (1) is folded so as to cover the triangular lower surface of the rice ball (5). As a result, the rice ball (5) is sandwiched between the packaging sheets bent in a substantially U-shape and aligned at both ends.
As shown in FIG. 6d, the center part of both ears of the packaging sheet (1) protruding from the rice ball (5) is folded inward.
As shown in FIG. 6e, the upper ear portion (11a) of the packaging sheet (1) is folded downward, and the lower ear portion (11b) is folded upward as shown in FIG. ) (11b) is folded and welded (16) to form the collar portion (17), and a rectangular bag (10) having one end opened (10a) is formed.
As shown in FIG. 6g, a bag opening (10a) is welded to form a sealing portion. As shown in FIG. 7a, the sealing portion is melted into a thick line across the severable portion (21) of the outer film (2), and further slightly inside the welded thick lines (19) and (19). Are welded in the shape of a thin line (18). The welded thin wire (18) is weakly welded to such an extent that it does not interfere with the division of the severable portion (21) of the outer film (2).

次に包装おにぎりについて説明する。
［包装おにぎり］
包装おにぎりは袋包装であるから、高級志向を満たし、又、おにぎり(５)を大きく見せることができる。
又、包装おにぎりは、上記の如く包装されているから、袋(10)を形成している包装シート(１)の外フィルム(２)上のカットテープ(22)は、おにぎり(５)の頂部から対辺の中央部を通って、おにぎりの背面に回りこみ、再び頂部へ戻っている。
包装シート(１)の内フィルム(３)を形成する２枚のフィルム片(31)(31)の重なり部(32)は、平行な２本の線状接合部(34)(34)によって接合されているため、重なり部(32)の口が開くことはない。従って袋包装状態のおにぎり(３)の湿気が、包装シート(１)内のシート状海苔(４)を湿気させることはなく、シート状海苔(４)の風味、食感を損なうことはない。 Next, packaging rice balls will be described.
[Packaging rice ball]
Since the packaged rice ball is a bag package, it satisfies high-class orientation, and the rice ball (5) can be shown large.
Since the packaged rice balls are packaged as described above, the cut tape (22) on the outer film (2) of the packaging sheet (1) forming the bag (10) is the top of the rice ball (5). From the other side, through the center of the opposite side, wrapping around the back of the rice ball and returning to the top again.
The overlapping part (32) of the two film pieces (31) (31) forming the inner film (3) of the packaging sheet (1) is joined by two parallel linear joining parts (34) (34). Therefore, the mouth of the overlapping portion (32) does not open. Therefore, the moisture of the rice balls (3) in the bag-packed state does not wet the sheet-like nori (4) in the packaging sheet (1), and does not impair the flavor and texture of the sheet-like nori (4).

［おにぎりを食するとき］
包装おにぎりの包装を解くには、一方の手で、外フィルム(２)の分断可能部(21)を中心として包装袋(10)の片方を、袋の上からおにぎり(５)を軽く掴む様にして保持する。他方の手で外フィルム(２)端部の切込み(23)(23)間を摘んで、該カットテープ(22)の長手方向に沿わせて他端側に引っ張る(図７ａ参照)。外フィルム(２)は、切込み(23)(23)間の幅で帯状に引き裂かれ二分される。 [When eating rice balls]
To unwrap the wrapped rice ball, with one hand, lightly grab the rice ball (5) from the top of the bag, centering on the severable part (21) of the outer film (2). And hold. With the other hand, the notches (23) and (23) at the ends of the outer film (2) are picked and pulled to the other end side along the longitudinal direction of the cut tape (22) (see FIG. 7a). The outer film (2) is torn into two bands with a width between the notches (23) and (23) and is divided into two.

外フィルム(２)を裂いた手で、袋(10)の端部を外側に引っ張る。
このとき、図５ａに示す内フィルム(３)の各フィルム片(31)(31)の分断可能部(35)(35)である断続的な切込み(36)が、フィルム片(31)の長手方向に繋がる様に裂けて、図５ｂに示す如く、両フイルム片(31)(31)が離れる。
即ち、外フィルム(２)の半分と、該半分の外フィルムに溶着された内フィルム(３)の一方のフィルム片(31)が引っ張り出され、シート状海苔(４)の半分とおにぎり(５)の半分が露出する(図７ｂ)。
該包装袋(10)の片側を引っ張った手で、露出したシート状海苔(４)の上からおにぎり(５)を保持し、他方の手で残された袋半分の端縁を摘んで、外側に引っ張る。
おにぎり(５)から包装袋(10)が完全に取り除かれ、シート状海苔(４)だけが残っておにぎり(５)に被さる。
これによって、新鮮なシート状海苔(４)が被さったおにぎり(５)を食することができる。
図７ｂに示す如く、包装袋(10)の半分がおにぎりに被さった状態で、該半分の包装袋の上からおにぎりを掴んで食すれば、おにぎりに直接に手が触れることなく、衛生的である。 Pull the end of the bag (10) outward with the hand that has torn the outer film (2).
At this time, intermittent cuts (36), which are severable portions (35) and (35) of the film pieces (31) and (31) of the inner film (3) shown in FIG. The film pieces (31) and (31) are separated as shown in FIG. 5b.
That is, half of the outer film (2) and one film piece (31) of the inner film (3) welded to the outer film of the half are pulled out, and half of the sheet-like seaweed (4) and rice ball (5 ) Is exposed (FIG. 7b).
Hold the rice ball (5) from above the exposed sheet-like seaweed (4) with the hand pulled on one side of the packaging bag (10), and pick the left edge of the bag half with the other hand, Pull on.
The packaging bag (10) is completely removed from the rice ball (5), and only the sheet-like nori (4) remains and covers the rice ball (5).
Thereby, rice balls (5) covered with fresh sheet-like seaweed (4) can be eaten.
As shown in FIG. 7b, in a state in which half of the packaging bag (10) is overlying the by Moody grip, if Shokusure grabbed the rice balls from the top of the half minute of the packaging bag, without directly touching hand to rice balls, Hygienic.

包装おにぎりは、外フィルム(２)の分断可能部(21)及び内フィルム(３)の分断可能部(35)(35)によって包装袋(10)の幅方向の中央部を裂くことができるため、上記の如く、包装を解く際に、常におにぎり(５)を手で保持しておくことができ、従来の様に、包装袋を２つに裂いた途端、おにぎりが袋から落下してしまうことを防止できる。 Because the packaging rice ball can tear the central part in the width direction of the packaging bag (10) by the separable part (21) of the outer film (2) and the separable part (35) (35) of the inner film (3). As mentioned above, the rice ball (5) can always be held by hand when unpacking, and as before, the rice balls fall from the bag as soon as the packaging bag is split into two. Can be prevented.

図８は、内フィルム(３)の線状接合部(34)と分断可能部(35)の第２実施例を示し、図８ａに示す如く、線状接合部(34)は内フィルム(３)のフィルム片(31)(31)の重なり部(32)の全長に亘って１本だけ施されている。
分断可能部(35)は、フィルム片(31)(31)の重なり部(32)にて重なり部の全長に亘って断続的な切込み(36)を施して形成されている。断続的な切込み(36)には他方のフィルム片の内側端部が被さるので、断続的な切込み(36)を通じて湿気が流通することは、完全ではなくとも効果的に防止される。
フィルム片(31)(31)を互いに離れる方向に引っ張ると、図８ｂに示す如く、分断可能部(35)から内フィルム(３)は２分される。 FIG. 8 shows a second embodiment of the linear joint portion (34) and the separable portion (35) of the inner film (3). As shown in FIG. 8a, the linear joint portion (34) is formed by the inner film (3). ) Film pieces (31) and (31) are provided only over the entire length of the overlapping portion (32).
The splittable portion (35) is formed by intermittently cutting (36) over the entire length of the overlapping portion at the overlapping portion (32) of the film pieces (31) and (31). Since the intermittent cut (36) covers the inner end of the other film piece, moisture is effectively prevented from flowing through the intermittent cut (36), if not completely.
When the film pieces (31) and (31) are pulled away from each other, as shown in FIG. 8b, the inner film (3) is divided into two from the severable portion (35).

図９は、内フィルム(３)の線状接合部(34)と分断可能部(35)の第３実施例を示している。
内フィルム(３)のフィルム片(31)(31)は、重なり部(32)にて互いに接触する面に、加圧によって弱い接着力を発揮するコーティング層を施しておき、細幅の回転ローラ(図示せず)によって、重なり部(32)を連続した線状に加圧することによりフィルム片(31)(31)を弱く接合している(図９ａ)。
両フィルム片(31)(31)を互いに離れる方向に引っ張ると、図９ｂに示す如く、線状接合部(34)からフィルム片(31)(31)が分離する。即ち、線状接合部(34)が分断可能部(35)を兼用しているのである。
図９の場合、フィルム片(31)(31)の重なり部(32)には、断続的な切込み等、空気が内フィルム(３)を通過する余地はないので、おにぎり(５)の湿気が、シート状海苔(４)に移ることを防止する効果は、一層顕著である。 FIG. 9 shows a third embodiment of the linear joint (34) and the separable part (35) of the inner film (3).
The film pieces (31) and (31) of the inner film (3) are provided with a coating layer that exerts a weak adhesive force when pressed on the surfaces of the overlapping portions (32) that are in contact with each other. The film pieces (31) and (31) are weakly joined by pressurizing the overlapping portion (32) in a continuous line shape (not shown) (FIG. 9a).
When the film pieces (31) and (31) are pulled away from each other, the film pieces (31) and (31) are separated from the linear joint (34) as shown in FIG. 9b. That is, the linear joint portion (34) also serves as the separable portion (35).
In the case of FIG. 9, since there is no room for air to pass through the inner film (3), such as intermittent cuts, in the overlapping part (32) of the film pieces (31) and (31), the humidity of the rice ball (5) The effect of preventing transfer to the sheet-like seaweed (4) is even more remarkable.

図１０は、図９の変形である第４実施例を示している。内フィルム(３)の線状接合部(34)は、フィルム片(31)(31)の重なり部(32)が口を開く余地のない程度に密なるピッチでフィルム片(31)(31)を断続的に接合して形成されている。線状接合部(34)の接合力は強くなく、フィルム片(31)(31)を互いに引き離す方向に引っ張ると、線状接合部(34)にてフィルム片(31)(31)が剥離して内フィルム(３)は、接合前の２枚のフィルム片(31)(31)に２分される。
線状接合部(34)は、多数の細く短い溶着線(34a)が、密なるピッチで且つフィルム片(31)(31)の重なり部(32)の長手方向に対して傾いた状態で平行に並んで形成されている。具体的には、０.５mm幅の仮想帯状領域に０.５mmピッチで溶着線(34a)が並んでおり、各溶着線(34a)は、フィルム片(31)(31)の重なり部(32)の長手方向に対して約４５°程度傾いている。
線状接合部(34)の形成は、外周縁に溶着線(34a)の配列に対応する模様を刻設した加熱ローラ(図示せず)を回転させつつフィルム片(31)(31)の重なり部(32)を押圧することによって行なう。 FIG. 10 shows a fourth embodiment which is a modification of FIG. The linear joint portion (34) of the inner film (3) is formed at a pitch that is dense enough to prevent the overlapping portion (32) of the film pieces (31) and (31) from opening. Are formed by intermittently joining. The bonding force of the linear joint portion (34) is not strong, and when the film pieces (31) (31) are pulled in directions away from each other, the film pieces (31) (31) peel off at the linear joint portion (34). The inner film (3) is divided into two film pieces (31) and (31) before joining.
The linear joint (34) is parallel with a large number of thin, short welding wires (34a) being inclined with respect to the longitudinal direction of the overlapping portion (32) of the film pieces (31) (31) at a dense pitch. Are formed side by side. Specifically, weld lines (34a) are arranged at a pitch of 0.5 mm in a virtual strip region having a width of 0.5 mm, and each weld line (34a) is an overlapping portion (32 of film pieces (31) and (31)). ) In the direction of about 45 °.
The linear joint (34) is formed by overlapping the film pieces (31) (31) while rotating a heating roller (not shown) in which a pattern corresponding to the arrangement of the weld lines (34a) is formed on the outer peripheral edge. This is done by pressing the part (32).

溶着線(34a)が、フィルム片(31)(31)の重なり部(32)の長手方向に沿って断続的に並ぶ様に線状接合部(34)を形成した場合、フィルム片(31)(31)の接合力が弱すぎる虞れがある。
溶着線(34a)が、フィルム片(31)(31)の重なり部(32)の長手方向に直交する様に線状接合部(34)を形成すれば、フィルム片(31)(31)の接合力が強すぎて、内フィルム(３)を簡単に二分出来ない。
実施例の様に、線状接合部(34)の各溶着線(34a)を斜めにすれば、フィルム片(31)(31)の接合が安定し、且つフィルム片(31)(31)を互いに離れる方向に引っ張ると線状接合部(34)にて容易に剥離して分離する。
但し、フィルム片(31)(31)の材質、コーティング層の特性、線状接合部(34)を形成するためのローラの加圧力、ローラの加熱温度等の条件によって、溶着線(34a)の最適の配列、溶着線(34a)の最適の傾き、溶着線(34a)の最適の長さ、太さ等を決めればよい。条件によっては溶着線(34a)でなく溶着ドットの配列でもよい。
要は、フイルム片(31)(31)を接合でき、包装状態でフィルム片(31)(31)の重なり部(32)の口が開かず、且つ、フィルム片(31)(31)を互いに離れる方向に引っ張ると容易に分離する条件を満たせば、線状接合部(34)のパターンは問わない。
フィルム片(31)(31)の重なり部(32)を上記の様な密なるピッチで断続的に接合して線状接合部(34)を形成すれば、線状接合部(34)の領域内の未接合部でもフィルム片(31)(31)どうしが密接して空気の流通を効果的に阻止できる。
実施例の様に、多数の溶着線(34a)をフィルム片(31)(31)の重なり部(32)の長手方向に対して４５°程度傾けて平行に密なるピッチで配列して線状接合部(34)を形成した場合、隣り合う溶着線(34a)(34a)間の空気の流通阻止効果は一段と向上し、図９に示すフィルム片(31)(31)の重なり部(32)に連続した線状接合部(34)を形成した場合の空気流通阻止効果と殆んど遜色はない。 When the linear joining portion (34) is formed so that the welding line (34a) is intermittently arranged along the longitudinal direction of the overlapping portion (32) of the film pieces (31) and (31), the film piece (31) (31) joining force there is a risk that too weak.
If the linear joining part (34) is formed so that the welding line (34a) is orthogonal to the longitudinal direction of the overlapping part (32) of the film pieces (31) (31), the film pieces (31) (31) The joining force is too strong, and the inner film (3) cannot be easily divided into two.
As in the example, if each welding wire (34a) of the linear joint portion (34) is slanted, the joining of the film pieces (31) (31) becomes stable, and the film pieces (31) (31) When pulled away from each other, they are easily separated and separated at the linear joint (34).
However, depending on conditions such as the material of the film pieces (31) and (31), the characteristics of the coating layer, the pressing force of the roller for forming the linear joint (34), the heating temperature of the roller, the welding wire (34a) What is necessary is just to determine the optimal arrangement | sequence, the optimal inclination of the welding line (34a), the optimal length, thickness, etc. of the welding line (34a). Depending on the conditions, an array of weld dots may be used instead of the weld line (34a).
In short, the film pieces (31) (31) can be joined together, the mouth of the overlapping part (32) of the film pieces (31) (31) is not opened in the packaged state, and the film pieces (31) (31) are mutually connected. The pattern of the linear joint (34) is not limited as long as the condition of being easily separated when pulled away is satisfied.
If the linear joining portion (34) is formed by intermittently joining the overlapping portions (32) of the film pieces (31) and (31) at a dense pitch as described above, the region of the linear joining portion (34) is obtained. Even in the unjoined portion, the film pieces (31) and (31) are in close contact with each other, and air flow can be effectively prevented.
As in the embodiment, a large number of welding wires (34a) are arranged at a dense pitch in parallel with an inclination of about 45 ° with respect to the longitudinal direction of the overlapping portion (32) of the film pieces (31) and (31). When the joining portion (34) is formed, the air flow blocking effect between the adjacent weld lines (34a) (34a) is further improved, and the overlapping portions (32) of the film pieces (31) (31) shown in FIG. When the continuous linear joint (34) is formed, there is almost no inferiority to the air flow blocking effect.

(22) can be divided exist Shinano without having the outer film (2). However, when the cutting tape (22) is applied, to cut the tape name the role of core tear width of the film, it can rip stably outer film (2).
One cut tape is acceptable.
In addition to the above, the severable portion (21) of the outer film (2) may have any configuration other than the above as long as the outer film (2) can be divided into two parts without using tools.

又、内フィルム(３)の両フィルム片(31)(31)の分断可能部(35)も、実施例の断続的な切込み(36)に限ることはない。例えば、フィルム片(31)の全長に亘ってフィルム片を貫通しない程度の浅い切条線(図示せず)を施す、又は、フィルム片(31)に加熱した回転刃を走らせて全長に亘って溶融固化線を形成する等により、他の部分より裂け易く、又は、他の部分より脆くなって分離し易くする等、道具を用いずに内フィルム(３)を二分できれば構成は問わない。 Further, the severable portion (35) of both the film pieces (31) and (31) of the inner film (3) is not limited to the intermittent cut (36) of the embodiment.
