Description

この発明は、サイドガセット部分を有するプラスチック袋に関するものである。   The present invention relates to a plastic bag having a side gusset portion.

特開２００４−１００５５号公報（特許文献１）に記載されているように、プラスチック袋にサイドガセット部分を形成することは一般的である。   As described in JP 2004-10055 A (Patent Document 1), it is common to form a side gusset portion in a plastic bag.

ところで、サイドガセット部分を有するプラスチック袋には大型のものが多く、内容物を充填し、収容したとき、その重量は相当大きい。このため、それを持ち運ぶことは容易ではない。   By the way, there are many large-sized plastic bags having side gusset portions, and their weight is considerably large when the contents are filled and stored. For this reason, it is not easy to carry it.

したがって、この発明は、サイドガセット部分を有するプラスチック袋を容易に持ち運ぶことを目的としてなされたものである。
特開２００４−１００５５号公報 Therefore, the present invention has been made for the purpose of easily carrying a plastic bag having a side gusset portion.
JP 2004-10055 A

この発明によれば、サイドガセット部分に取っ手が形成される。   According to the present invention, the handle is formed on the side gusset portion.

図１はこの発明にかかる取っ手１を示す。この取っ手１は帯状のプラスチックフィルムからなり、その両端は拡大された幅Ｗをもつ。さらに、両端に種々の形状が与えられ、図５および図６に示すように、サイドガセット部分２を有するプラスチック袋において、両端がサイドガセット部分２の表面に貼り付けられる。たとえば、ホットメルト、ヒートシール、両面テープまたは超音波シールによって両端が貼り付けられ、その貼り付け部分３が形成される。   FIG. 1 shows a handle 1 according to the present invention. The handle 1 is made of a strip-shaped plastic film, and both ends thereof have an enlarged width W. Furthermore, various shapes are given to both ends, and as shown in FIGS. 5 and 6, in the plastic bag having the side gusset portion 2, both ends are attached to the surface of the side gusset portion 2. For example, both ends are pasted by hot melt, heat sealing, double-sided tape or ultrasonic sealing, and the pasting portion 3 is formed.

したがって、サイドガセット部分２に取っ手１が形成されるものである。したがって、取っ手１によってプラスチック袋をぶら下げ、これを容易に持ち運ぶことができる。さらに、ぶら下げたとき、重量によって取っ手１およびサイドガセット部分２が変形する。図５および図６はその状態を示す。   Therefore, the handle 1 is formed on the side gusset portion 2. Therefore, the plastic bag can be hung by the handle 1 and can be easily carried. Furthermore, when hanging, the handle 1 and the side gusset portion 2 are deformed by weight. 5 and 6 show this state.

取っ手１および貼り付け部分３に図２の形状をもたせてもよい。   The handle 1 and the attaching portion 3 may have the shape shown in FIG.

図３に示すように、プラスチックフィルムに切り抜き線４を形成し、切り抜き線４間でプラスチックフィルムをつかみ、握り、取っ手１を形成してもよい。   As shown in FIG. 3, the cut line 4 may be formed in the plastic film, and the handle 1 may be formed by grasping the plastic film between the cut lines 4 and gripping it.

図４に示すように、取っ手１の中央部分に幅をもたせ、手でこれをつかんだとき、中央部分がその幅方向両側で上方または下方に湾曲するようにしてもよい。   As shown in FIG. 4, a width may be given to the central portion of the handle 1, and when this is grasped by hand, the central portion may be curved upward or downward on both sides in the width direction.

なお、上記公報に記載されているように、サイドガセット部分を有するプラスチック袋の製袋機では、図７に示すように、サイドガセット材５が幅方向両側から２つ折りされ、胴材６に供給される。   As described in the above publication, in a bag making machine for plastic bags having a side gusset portion, as shown in FIG. 7, the side gusset material 5 is folded in half from both sides in the width direction and supplied to the body 6. Is done.

したがって、図８に示すように、たとえば、取っ手材７をロール８から供給し、ホットメルトテープ９をロール１０から供給し、取っ手材７に貼り付け、所要長さに切断する。その後、トムソン刃１１を取っ手材７およびホットメルトテープ９に押し付け、取っ手材７が取っ手１の形状に切断され、不要個所１４でホットメルトテープ９が除去されるようにする。さらに、ミシン目刃１２を取っ手材７およびホットメルトテープ９に押し付け、取っ手材７およびホットメルトテープ９にミシン目１３を形成する。その後、取っ手材７をローラ１５とテフロン（登録商標）ベルト１６間に挟み、取っ手材７をミシン目１３で引きちぎり、テフロンベルト１６によって取っ手材７を送り、ヒータ１７によってそれを加熱する。そして、図７のサイドガセット材５の２つ折り前、位置１８において、取っ手材７をサイドガセット材５に供給すると、サイドガセット材５の表面において、ホットメルトテープ９によって取っ手材７を貼り付けることができる。   Therefore, as shown in FIG. 8, for example, the handle material 7 is supplied from the roll 8, the hot melt tape 9 is supplied from the roll 10, attached to the handle material 7, and cut to a required length. Thereafter, the Thomson blade 11 is pressed against the handle material 7 and the hot melt tape 9 so that the handle material 7 is cut into the shape of the handle 1 so that the hot melt tape 9 is removed at the unnecessary portion 14. Further, the perforation blade 12 is pressed against the handle material 7 and the hot melt tape 9 to form the perforation 13 on the handle material 7 and the hot melt tape 9. Thereafter, the handle material 7 is sandwiched between the roller 15 and the Teflon (registered trademark) belt 16, the handle material 7 is torn off at the perforation 13, the handle material 7 is fed by the Teflon belt 16, and the heater 17 heats it. When the handle material 7 is supplied to the side gusset material 5 at the position 18 before the side gusset material 5 is folded in two in FIG. 7, the handle material 7 is attached to the surface of the side gusset material 5 by the hot melt tape 9. Can do.

図９はサイドガセット材５に貼り付けられた取っ手材７を示す。サイドガセット材５はその中心線１８および折り曲げ線１９を有する。   FIG. 9 shows the handle material 7 attached to the side gusset material 5. The side gusset material 5 has a center line 18 and a fold line 19.

図７のサイドガセット材５の２つ折り後、位置１９において、図１０に示すように、クランプ部材によって取っ手１をクランプし、これをサイドガセット材５の両層間に挿入するようにしてもよい。   After folding the side gusset material 5 of FIG. 7 in half, as shown in FIG. 10, the handle 1 may be clamped by a clamp member at a position 19 and inserted between both layers of the side gusset material 5.
