Description
本考案は、開封構造を改良したチャック付き包装袋に関するものである。 The present invention relates to a packaging bag with a zipper having an improved opening structure.
菓子や食品などを包装する袋は、合成樹脂フイルムやラミネートフイルムで形成された表裏２枚のフイルムを重ね、その周縁部を熱シールして袋状に形成し、熱シール部に切欠部を設け、これを横方向に引き裂いて開封するものが一般に使用されている。内容物が一度に食べ切れないものは、内側にチャックを設けたチャック付き包装袋が使用され、チャックを開閉することにより、内容物を反復して取り出すことができるチャック付き包装袋（特許文献１）もある。 Bags for packaging confectionery, foods, etc. are formed in a bag shape by stacking two front and back films made of synthetic resin film or laminate film, and heat-sealing the peripheral edge of the bag. In general, those that are torn open in the lateral direction are used. If the contents cannot be eaten at once, a packaging bag with a chuck provided with a chuck on the inside is used. By opening and closing the chuck, the packaging bag with a chuck can be taken out repeatedly (Patent Document 1) There is also.
しかしながら、従来のチャック付き包装袋１は、図６（Ａ）に示すようにチャック２の上方の左側の熱シール部３に形成した切欠部４を横方向に引き裂いて図６（Ｂ）に示すように開封すると、その断面形状は図７（Ａ）から図７（Ｂ）に示す状態となる。しかしながらこの場合、引き裂いたチャック上部の軟質な表裏のフイルム５ａ、５ｂの隙間が狭く、指で開けにくい問題があった。 However, the conventional packaging bag 1 with a chuck is shown in FIG. 6 (B) by tearing the notch 4 formed in the left heat seal part 3 above the chuck 2 in the lateral direction as shown in FIG. 6 (A). When opened, the cross-sectional shape is as shown in FIGS. 7A to 7B. However, in this case, there is a problem that the gap between the soft front and back films 5a and 5b at the top of the torn chuck is narrow and it is difficult to open with fingers.
この原因について検討したところ、チャック２を構成する帯状のベース片６ａに突条部７を設けた雄チャック２ａと、帯状のベース片６ｂに溝条部８を設けた雌チャック２ｂとは、表裏のフイルム５ａ、５ｂに比べて厚く、可撓性が少ないので、雄チャック２ａと雌チャック２ｂが嵌合してシールされている状態では、図７（Ｂ）に示すように引き裂いた軟質なフイルム５ａ、５ｂはほぼ密着した状態になるためであると考えられる。 When this cause is examined, the male chuck 2a in which the strip-like base piece 6a constituting the chuck 2 is provided with the protrusion 7 and the female chuck 2b in which the strip-like base piece 6b is provided with the groove 8 are the front and back sides. The film 5a, 5b is thicker and less flexible, so when the male chuck 2a and the female chuck 2b are fitted and sealed, a soft film that is torn as shown in FIG. 5a and 5b are considered to be in an almost intimate contact state.
特に耐候性や耐湿性に優れたアルミニウムを蒸着したラミネートフイルムは厚く、可撓性が少ないので、チャック２がシールされた状態では、ベース片６ａ、６ｂの上のフイルム５ａ、５ｂの長さにもよるが開封しにくく、ベース片６ａ、６ｂの上まで切り裂いた場合は更に開けにくい問題があった。 In particular, a laminated film deposited with aluminum having excellent weather resistance and moisture resistance is thick and less flexible. Therefore, when the chuck 2 is sealed, the length of the films 5a and 5b on the base pieces 6a and 6b is reduced. However, it is difficult to open, and when the base pieces 6a and 6b are cut up, there is a problem that it is difficult to open.
本考案は上記問題を改善し、チャック上部の表裏２枚のフイルムを引き裂いた時に、フイルムを指でつかみ易くして、チャックの開封が容易なチャック付き包装袋を提供するものである。 The present invention improves the above problem, and provides a packaging bag with a chuck that makes it easy to grasp the film with fingers when the two films on the top and bottom of the chuck are torn, and the chuck can be easily opened.
本考案の請求項１記載のチャック付き包装袋は、熱融着性の合成樹脂フイルムまたはラミネートフイルムで形成された表裏２枚のフイルムを重ね、その周縁部を熱シールして袋状に形成し、上縁側の内側にチャックを設けると共に、チャック上方の左右少なくとも何れかの熱シール部に切欠部を設けたチャック付き包装袋において、前記チャックを構成する、帯状のベース片に突条部を設けた雄チャックと、帯状のベース片に前記突条部が嵌合する溝条部を設けた雌チャックとの何れか一方のベース片を、他方のベース片よりその上部の高さを変えて段違いに形成したことを特徴とするものである。 The packaging bag with a zipper according to claim 1 of the present invention is formed in a bag shape by stacking two front and back films formed of a heat-sealable synthetic resin film or a laminate film, and heat-sealing the peripheral portion. In a packaging bag with a chuck provided with a chuck on the inner side of the upper edge side and provided with a notch in at least one of the left and right heat seal portions above the chuck, a strip-shaped base piece constituting the chuck is provided with a protrusion. One of the base pieces of the male chuck and the female chuck provided with a groove portion into which the protruding portion is fitted to the belt-like base piece is stepped differently by changing the height of the upper part of the other base piece. It is characterized in that it is formed.
本考案の請求項２記載のチャック付き包装袋は、請求項１において、表側のフイルムに設けた雄チャックまたは雌チャックのベース片が、裏側のフイルムに設けた雌チャックまたは雄チャックのベース片より上部を低くして段違いに形成されていることを特徴とするものである。 The packaging bag with a chuck according to claim 2 of the present invention is the packaging bag with a chuck according to claim 1, wherein the base piece of the male chuck or the female chuck provided on the front film is more than the base piece of the female chuck or the male chuck provided on the back film. It is characterized in that it is formed in a stepped shape with the upper part lowered.
本考案の請求項３記載のチャック付き包装袋は、請求項１において、雄チャックのベース片と、雌チャックのベース片との上部が５ｍｍ以上の段違いに形成されていることを特徴とするものである。 The packaging bag with a chuck according to claim 3 of the present invention is characterized in that, in claim 1, the upper part of the base piece of the male chuck and the base piece of the female chuck is formed in a step difference of 5 mm or more. It is.
本考案の請求項４記載のチャック付き包装袋は、請求項１において、ラミネートフイルムがアルミニウムを蒸着したラミネートフイルムであることを特徴とするものである。 The packaging bag with a chuck according to claim 4 of the present invention is characterized in that, in claim 1, the laminate film is a laminate film in which aluminum is deposited.
本考案に係る請求項１記載のチャック付き包装袋によれば、チャックを構成する、帯状のベース片に突条部を設けた雄チャックと、帯状のベース片に前記突条部が嵌合する溝条部を設けた雌チャックとの何れか一方のベース片を、他方のベース片よりその上部の高さを変えて段違いに形成することにより、切欠部に沿ってフイルムが裂けると、一方のフイルムは、上部が高いベース片が取付けられているので、この上部より下は裂けず、また上部が低いベースを取付けた他方のフイルムも同様の高さまでしか裂けないので、他方のフイルムは広く残る。このため一方のフイルムは、厚いベース片との距離が短く可撓性は少ないが、他方のフイルムは広く残っているので可撓性があり、この部分を指先で引っ掛けると撓んで広い隙間ができ、指でつかみ易く、チャック２の開封が容易である。 According to the packaging bag with a chuck according to claim 1 of the present invention, the male chuck having the strip-like base piece provided with the ridge portion constituting the chuck, and the ridge portion fit into the strip-like base piece. If one of the base pieces of the female chuck provided with the groove portion is formed in a step difference by changing the height of the upper part of the other base piece, when the film tears along the notch, The film has a base piece with a high upper part attached, so that the lower part of this film does not tear, and the other film with a lower base attached has a similar height, so the other film remains wide. . For this reason, one film has a short distance from the thick base piece and is less flexible, but the other film remains wide, so it is flexible. When this part is hooked with a fingertip, it is bent and a wide gap is formed. It is easy to grasp with a finger and the chuck 2 is easy to open.
また請求項２記載のチャック付き包装袋によれば、表側のフイルムに設けた雄チャックまたは雌チャックのベース片が、裏側のフイルムに設けた雌チャックまたは雄チャックのベース片より上部を低くして段違いに形成されているので、表側のベース片の上のフイルムが広く残ってつかみ易く、開封が容易である。 According to the packaging bag with a chuck according to claim 2, the base piece of the male chuck or the female chuck provided on the front film is made lower than the base piece of the female chuck or the male chuck provided on the back film. Since it is formed in steps, the film on the base piece on the front side remains wide and easy to grasp and can be opened easily.
また請求項３記載のチャック付き包装袋によれば、雄チャックのベース片と、雌チャックのベース片との上部が５ｍｍ以上の段違いに形成されているので指先でフイルムがつかみ易く、開封が容易で段差は５〜１０ｍｍが望ましい。 Further, according to the packaging bag with a chuck according to claim 3, since the upper part of the base piece of the male chuck and the base piece of the female chuck is formed in a step difference of 5 mm or more, the film can be easily grasped by the fingertip and easy to open. The step is preferably 5 to 10 mm.
また請求項４記載のチャック付き包装袋によれば、耐候性や耐湿性に優れたアルミニウムを蒸着したラミネートフイルムを用いることにより厚く、可撓性が少ないが、一方のベース片が他方のベース片より上部の高さが低く形成されているのでこの部分を指先で引っ掛けると撓んで開封し易い。 Further, according to the packaging bag with a chuck according to claim 4, one base piece is the other base piece although it is thick and less flexible by using a laminated film deposited with aluminum having excellent weather resistance and moisture resistance. Since the height of the upper part is formed lower, if this part is hooked with a fingertip, it is easily bent and opened.
以下本考案の実施の一形態を図１ないし図４を参照して詳細に説明する。図において１はチャック付き包装袋を示すもので、熱融着性の合成樹脂フイルムで形成された表裏２枚のフイルム５ａ、５ｂを重ね、その周縁部を熱シールして袋状に形成し、上部左側の熱シール部３にＶ形の切欠部４が形成され、内側に雄チャック２ａと雌チャック２ｂを組合せたチャック２が設けられている。 Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. In the figure, reference numeral 1 denotes a packaging bag with a zipper, which is formed by stacking two front and back films 5a and 5b formed of a heat-sealable synthetic resin film, and heat-sealing the peripheral portion to form a bag shape. A V-shaped cutout 4 is formed in the upper left heat seal portion 3, and a chuck 2 in which a male chuck 2 a and a female chuck 2 b are combined is provided inside.
雄チャック２ａは、図２に示すように帯状のベース片６ａの片面に、その長手方向に沿って、先端が断面円形状の突条部７が形成され、他方の面はフイルム５ａに熱融着されている。また雌チャック２ｂは帯状のベース片６ｂの片面に、その長手方向に沿って、先端に前記突条部７が着脱自在に嵌合する溝を形成した溝条部８が形成され、他方の面はフイルム５ｂに熱融着されている。雄チャック２ａの帯状のベース片６ａの上部の高さは、雌チャック２ｂの帯状のベース片６ａの上部の高さより約５〜１０ｍｍ程低く段違いに形成されている。 As shown in FIG. 2, the male chuck 2a is formed with a protrusion 7 having a circular cross-section at one end of the strip-shaped base piece 6a along the longitudinal direction thereof, and the other surface is thermally fused to the film 5a. It is worn. The female chuck 2b has a groove 8 formed on one surface of the strip-shaped base piece 6b along the longitudinal direction thereof, in which a groove into which the protrusion 7 is detachably fitted is formed at the tip. Is heat-sealed to the film 5b. The height of the upper part of the strip-like base piece 6a of the male chuck 2a is formed in a step difference that is about 5 to 10 mm lower than the height of the upper part of the strip-like base piece 6a of the female chuck 2b.
上記構成のチャック付き包装袋１は、切欠部４の両側を手でつかんで引き裂くと切欠部４に沿ってフイルム５ａ、５ｂが裂けて図３に示すように上部が分離される。この断面状態は図４に示すように裏側のフイルム５ｂは、雌チャック２ｂの帯状のベース片６ｂの上に少し残るが、表側のフイルム５ａは、雄チャック２ａの帯状のベース片６ａの上に広く残る。 When the packaging bag with a chuck 1 having the above structure is torn by grasping both sides of the notch portion 4 by hand, the films 5a and 5b are torn along the notch portion 4 and the upper portion is separated as shown in FIG. In this cross-sectional state, as shown in FIG. 4, the film 5b on the back side remains a little on the strip-shaped base piece 6b of the female chuck 2b, but the film 5a on the front side remains on the strip-shaped base piece 6a of the male chuck 2a. Remains widely.
つまり切欠部４に沿ってフイルム５ａ、５ｂは裂けるが、裏側のフイルム５ｂは厚い帯状のベース片６ｂが取付けられているのでこの上部より下は裂けず、また表側のフイルム５ａに取付けた帯状のベース片６ａは、ベース片６ｂより上部が低いので、表側のフイルム５ａは少なくともベース片６ｂの高さまで広く残ることになる。 That is, although the films 5a and 5b are torn along the notch portion 4, the back film 5b is not torn below the upper part because the thick strip-like base piece 6b is attached, and is also attached to the front film 5a. Since the upper part of the base piece 6a is lower than the base piece 6b, the front film 5a remains wide at least up to the height of the base piece 6b.
このため裏側のフイルム５ｂは、厚い帯状のベース片６ｂとの距離が短く可撓性は少ないが、表側のフイルム５ａは、広く残っているので可撓性があり、この部分を指先で引っ掛けると撓んで、裏側のフイルム５ｂとの間に広い隙間ができ、指でつかみ易くなる。従って従来のように、帯状のベース片６ａ、６ｂの上部の高さが同じチャック２のように、フイルム５ａ、５ｂが密着せず開封が容易である。 For this reason, the film 5b on the back side has a short distance from the thick strip-shaped base piece 6b and is less flexible, but the film 5a on the front side is flexible because it remains widely, and if this part is hooked with a fingertip, It bends and a wide gap is formed between the film 5b on the back side and it becomes easy to grasp with a finger. Therefore, unlike the conventional case, the films 5a and 5b are not in close contact with each other like the chuck 2 having the same height at the top of the strip-like base pieces 6a and 6b, and can be easily opened.
また耐候性や耐湿性に優れたアルミニウムを蒸着したラミネートフイルム５ａ、５ｂは１枚の合成樹脂フイルムに比べて厚く、可撓性が少ないが、雄チャック２ａのベース片６ａの上部の高さを、雌チャック２ｂのベース片６ａの上部の高さより低く形成しているので、表側のラミネートフイルム５ａは広く残り、この部分を指先で引っ掛けると撓んで開封し易い。 Laminate films 5a and 5b on which aluminum having excellent weather resistance and moisture resistance is deposited are thicker and less flexible than one synthetic resin film, but the height of the upper part of the base piece 6a of the male chuck 2a is reduced. Since the upper part of the base piece 6a of the female chuck 2b is formed to be lower than the upper part, the front side laminate film 5a remains wide. When this part is hooked with a fingertip, it is bent and easily opened.
また図５は本考案の他の実施の形態を示すもので、左側の熱シール部３に設けたＶ形の切欠部４を斜め下方に向けて形成したものである。また切欠部４はＶ形に限らず、長方形状や線状のスリットでも良い。また切欠部４は左右の熱シール部３の何れか一方、または両方に形成しても良い。 FIG. 5 shows another embodiment of the present invention, in which a V-shaped notch 4 provided in the left heat seal portion 3 is formed obliquely downward. The cutout 4 is not limited to a V shape, and may be a rectangular or linear slit. Further, the cutout 4 may be formed in either one or both of the left and right heat seal portions 3.
なお本考案では、雄チャック２ａのベース片６ａと雌チャック２ｂのベース片６ｂとの上部が５ｍｍ以上離れた段違いに形成されているので指でつかみ易いが、これ未満では余り効果はない。また上記説明では雄チャック２ａのベース片６ａを雌チャック２ｂのベース片６ｂより低く形成した場合について示したが、この逆の構造でも良い。 In the present invention, since the upper part of the base piece 6a of the male chuck 2a and the base piece 6b of the female chuck 2b are formed in a step difference of 5 mm or more, it is easy to grasp with a finger. In the above description, the case where the base piece 6a of the male chuck 2a is formed lower than the base piece 6b of the female chuck 2b is shown.
