Description

本発明は、フィルムシートを用いてティッシュペーパー等を梱包する梱包体の製造方法に関するものである。   The present invention relates to a method for manufacturing a package that packs tissue paper or the like using a film sheet.

ティッシュペーパーを梱包するとき、厚紙を用いて数百枚のティッシュペーパーを収納できる大きさの包装箱を製造し、これに当該ティッシュペーパーを束状に折り重ねて収納していた。
ティッシュペーパーを数百枚単位で束ねた場合には、相当の強度が生じることから、上記の厚紙に代えて樹脂製のフィルムシートを用いて包装した、いわゆるピロー包装を施したものがある。 When packing tissue paper, a cardboard was used to produce a packaging box that was large enough to store hundreds of tissue paper, and the tissue paper was folded into a bundle and stored.
When tissue paper is bundled in units of several hundred sheets, a considerable strength is generated. Therefore, there is a paper package that is so-called pillow wrapping that uses a resin film sheet instead of the above-mentioned cardboard.

ティッシュペーパーのピロー梱包体は、包装されたティシュペーパーを使い切った後に、厚紙製の箱ごみが生じないようにしたもので、厚紙製の包装箱と概ね同様な大きさに形成されており、内包されているティッシュペーパーを取り出す開口部も、上記の包装箱と概ね同様な位置に設けられている。   The pillow package of tissue paper is designed to prevent cardboard box waste from being generated after the packed tissue paper has been used up. An opening for taking out the tissue paper is also provided at a position substantially similar to that of the packaging box.

ピロー梱包体の開口部は、当該梱包体を製造するとき、例えば、フィルムシートの表面にミシン目の穴（等長、等間隔の穴）を設ける加工が施され、工場出荷時等において当該開口部は封止されている。
また、使用者がティッシュペーパーを使用するとき、線状のミシン目を手で開封し、梱包体からティッシュペーパーを１枚、あるいは２枚１組ずつ取り出すことができるように構成されている（例えば、特許文献１参照）。 When the packaging body is manufactured, the opening of the pillow packaging body is subjected to, for example, a process of providing perforated holes (equal length, equally spaced holes) on the surface of the film sheet. The part is sealed.
Further, when the user uses the tissue paper, the line perforation is opened by hand, and the tissue paper can be taken out from the package one by one or two by one (for example, , See Patent Document 1).

また、樹脂製のフィルムシートを用いたピロー梱包体には、当該ピロー梱包体の上面に蓋フラップを設置し、蓋フラップを持ち上げることにより、ミシン目に沿って取出口を開けるように構成したものがある（例えば、特許文献２参照）。   In addition, the pillow packaging body using a resin film sheet is configured such that a lid flap is installed on the upper surface of the pillow packaging body, and the lid flap is lifted to open the outlet along the perforation. (See, for example, Patent Document 2).

従来の樹脂製フィルムシートを用いた梱包体は、上記のように構成されているので、封止された開口部を手で開封するとき、力を加えた開口部周辺において、フィルムシートに延びなどが生じることがあり、開口部周辺を強く押さえながらミシン目に沿って開口する力を加えなければならないという問題点があった。
また、開封を容易にするため、蓋フラップ等を樹脂製フィルムシートを用いた梱包体に設置した場合、当該フィルムシートと蓋フラップとを接合するための工数が増加し、製造コストが上昇して生産販売を実際に行うことが難しくなるという問題点があった。 Since the packaging body using the conventional resin film sheet is configured as described above, when opening the sealed opening by hand, it extends to the film sheet around the opening where force is applied, etc. There is a problem that a force for opening along the perforation must be applied while strongly pressing the periphery of the opening.
In addition, when a lid flap or the like is installed in a packaging body using a resin film sheet for easy opening, the number of steps for joining the film sheet and the lid flap increases, and the manufacturing cost increases. There was a problem that it was difficult to actually carry out production and sales.

本発明は、上記の問題点に鑑みなされたもので、梱包体の封止された開口部を容易に開封することができるように製造する梱包体の製造方法を提供することを目的とする。   The present invention has been made in view of the above problems, and an object of the present invention is to provide a method for manufacturing a package that is manufactured so that the sealed opening of the package can be easily opened.

The perforated holes having different hole lengths along the direction are formed in a linear shape.

また、前記第１過程は、刃渡り長さが徐々に変化するように前記複数の薄刃を並べたカッターを用いて、前記線状の中央部分で最も穴長さが長くなり、前記線状の各端部へ向かって徐々に穴長さが短くなる前記ミシン目の穴を形成させることを特徴とする。   Further, the first process uses a cutter in which the plurality of thin blades are arranged so that the blade span length gradually changes, and the hole length becomes the longest in the linear central portion, The perforated holes are formed so that the hole length gradually decreases toward the end.

また、前記第１過程は、前記線状の中央部分で穴長さが最も長いミシン目穴は、１本の指先が入る程度の長さであることを特徴とする。   Further, the first step is characterized in that the perforated hole having the longest hole length in the linear central portion is long enough to accommodate one fingertip.

また、前記第１過程は、回転駆動手段によって回転する支持部材の外周部位に前記複数の薄刃を並べたカッターを、前記フィルムシートの所定位置に当接させて前記回転駆動手段を稼働し、前記ミシン目の穴を形成させることを特徴とする。   In the first step, the rotary drive unit is operated by bringing a cutter in which the plurality of thin blades are arranged on the outer peripheral portion of the support member rotated by the rotary drive unit into contact with a predetermined position of the film sheet, A perforated hole is formed.

また、前記第５過程は、昇降手段によって昇降する支持部材の下端に前記複数の薄刃を並べたカッターを、前記フィルムシートの所定位置に前記昇降手段を用いて当接させ、前記ミシン目の穴を形成させることを特徴とする。   In the fifth step, a cutter in which the plurality of thin blades are arranged at a lower end of a support member that is lifted and lowered by a lifting and lowering means is brought into contact with a predetermined position of the film sheet using the lifting and lowering means. Is formed.

本発明によれば、比較的大きな梱包体を樹脂製のフィルムシートを用いて形成した場合に、容易に開封可能な開口部を、コストを抑えて設けることができる。   According to the present invention, when a relatively large package is formed using a resin film sheet, an opening that can be easily opened can be provided at low cost.

FIG. 2A shows a schematic arrangement relationship between the cutter 20 and the packing sheet 10 provided in the manufacturing apparatus when the manufacturing apparatus in which the perforated holes are provided in the packing sheet 10 is viewed from the side. FIG. 2B is a top view of a part of the packing sheet 10 and shows perforation openings 12 (each perforation hole) provided in the packing sheet 10 by the manufacturing apparatus shown in FIG. ing.
The packaging body 1 shown in FIG. 1 is manufactured by folding, for example, two sheets of tissue paper into two by using a manufacturing apparatus (not shown) and bundling 200 sets thereof.
On the other hand, an arbitrary resin film sheet is cut into a predetermined size (and a predetermined shape) to produce a packaging sheet 10, which is fixed, for example, in a flush state, and later becomes the upper surface when the tissue paper bundle 11 is packaged. A perforation opening 12 is formed at the site. In the manufacturing method of the package of Example 1, the perforation opening 12 is formed using the cutter 20 shown in FIG.

カッター２０は、円盤状もしくは円柱状の支持部材２２の外周部分に、薄刃の切込刃２１が複数個並べて設置固定されている。ここで、上記の外周部分に沿って並べられた切込刃２１は、それぞれ刃渡りの長さが異なり、これらの刃先部分が直線状となるように設置固定されている。
また、カッター２０の切込刃２１は、刃渡り長さが徐々に変化するように並べられており、各切込刃２１が梱包シート１０に当接することによって、当該梱包シート１０に形成される切込部分、即ち、ミシン目開口部１２は、図２（ｂ）に示したように形成される。 The cutter 20 has a plurality of thin cutting blades 21 arranged and fixed on the outer peripheral portion of a disk-shaped or columnar support member 22. Here, the cutting blades 21 arranged along the outer peripheral portion have different blade span lengths, and are installed and fixed so that the cutting edge portions are linear.
In addition, the cutting blades 21 of the cutter 20 are arranged so that the blade span length gradually changes, and the cutting blades 21 are in contact with the packing sheet 10 to form the cutting sheet 10 formed on the packing sheet 10. The recessed portion, that is, the perforated opening 12 is formed as shown in FIG.

ミシン目開口部１２に設けられているミシン目穴は、前述のように各ミシン目穴の間隔は同一で、ミシン目開口部１２の延設方向に沿った穴長さが異なっている。即ち、カッター２０は、円周方向において、各切込刃２１の間隔が同一となるように、また、各切込刃２１の刃高が同一となるように構成されている。なお、各切込刃２１は、各々の刃先をカッター２０の法線方向に向けて支持部材２２に固定されている。
また、カッター２０は、円周状に配置された各切込刃２１のうち、隣り合う始端切込刃２１Ｓ及び終端切込刃２１Ｅが最も刃渡りが短く、これらから離れた位置に配置されたものほど刃渡りが長くなり、例えば、支持部材２２の円状中心点を基点として、始端切込刃２１Ｓおよび終端切込刃２１Ｅと対向する位置に配置された切込刃２１が、最も刃渡りが長く構成されている。 As described above, the perforation holes provided in the perforation opening 12 have the same interval between the perforation holes and have different hole lengths along the extending direction of the perforation opening 12. That is, the cutter 20 is configured such that the intervals between the cutting blades 21 are the same in the circumferential direction, and the blade heights of the cutting blades 21 are the same. Note that each cutting blade 21 is fixed to the support member 22 with its cutting edge directed in the normal direction of the cutter 20.
In addition, the cutter 20 has a cutting edge 21S and a cutting edge 21E that are adjacent to each other among the cutting edges 21 that are arranged in a circumferential shape, and are arranged at positions that are separated from these. For example, the cutting blade 21 arranged at a position facing the start end cutting blade 21S and the end cutting blade 21E with the circular center point of the support member 22 as a base point is configured to have the longest blade span. Has been.

カッター２０を用いてミシン目開口部１２を形成するときには、初めに梱包シート１０を平坦な状態として固定し、例えば、カッター２０を上方から下降させて、梱包シート１０の所定位置に、カッター２０の始端切込刃２１Ｓを当接させる。

前述のように、カッター２０が梱包シート１０の表面上を回転しながら移動することによって、直線状の各ミシン目穴が形成され、始端ミシン目穴１２Ｓおよび終端ミシン目穴１２Ｅは、ミシン目開口部１２のミシン目穴のなかで最も穴長さが短く形成されたものである。また、他のミシン目開口部１２の各ミシン目穴は、始端ミシン目穴１２Ｓから離れるほど、また、終端ミシン目穴１２Ｅから離れるほど、穴長さが徐々に長くなり、ミシン目開口部１２の中央部において最も穴長さが長くなるように形成される。 By rotating and moving the cutter 20 as described above, the perforation opening 12 (perforation holes) shown in FIG. 2B is formed. A start perforation hole 12S is formed at a site where the start end cutting blade 21S abuts, and each perforation hole is formed by the rotation and movement of the cutter 20, and the end perforation 21E is contacted at the site where the end cutting blade 21E abuts. Eye holes 12E are formed.
As described above, the cutter 20 moves while rotating on the surface of the packing sheet 10 to form each linear perforation hole, and the start perforation hole 12S and the end perforation hole 12E have a perforation opening. The hole length is the shortest among the perforated holes of the portion 12. In addition, the perforation holes of the other perforation openings 12 gradually increase in length as the distance from the start perforation hole 12S increases from the end perforation hole 12E. It is formed so that the hole length becomes the longest in the central part of the.

直線状に並べられた切込刃４１は、当該直線状の一端に配置された端部切込刃４１Ｓ、および、他端に配置された端部切込刃４１Ｅの各刃渡りが最も短く形成されている。また、直線状に配置された各切込刃４１は、直線状の端部に配置されたものから中央部に配置されたものへ近付くにつれて、各々の刃渡りが徐々に長く形成され、直線状の中央部に配置されたものが最も長い刃渡りを有するように形成されている。 Here, the cutter 40 includes a plurality of cutting blades 41 protruding downward at the lower end portion of the support member 42. The thin cutting blades 41 are aligned and fixed in a straight line at equal intervals while aligning the blade crossing direction.
Each cutting blade 41 installed on the support member 42 is fixed with the cutting edge facing downward and with the height of the cutting edge aligned.
The cutting blades 41 arranged in a straight line are formed so that each edge span of the end cutting blade 41S arranged at one end of the linear shape and the end cutting blade 41E arranged at the other end is the shortest. ing. Moreover, as each cutting blade 41 arranged in a straight line approaches the one arranged in the central part from the one arranged in the linear end part, each blade span is formed gradually longer, The one arranged at the center is formed to have the longest blade span.

前述のように所定形状に形成した梱包シート１０を、平坦な状態として固定し、昇降手段６０を稼働してカッター４０を下降させ、直線状に並んだ全ての切込刃４１を梱包シート１０の所定位置に当接させる。切込刃４１を押し当てることにより、梱包シート１０に切込が入り、図３（ｂ）に示したミシン目開口部１２（直線状に並んだ各ミシン目穴）が形成される。
カッター４０を下降させたとき、端部切込刃４１Ｓが当接した部位に端部ミシン目穴５２Ｓが形成され、端部切込刃４１Ｅが当接した部位に端部ミシン目穴５２Ｅが形成される。また、端部切込刃４１Ｓと端部切込刃４１Ｅとの間に配置された各切込刃４１によって、端部ミシン目穴５２Ｓと端部ミシン目穴５２Ｅとの間に配置された各ミシン目穴が形成される。 The packing sheet 10 formed in a predetermined shape as described above is fixed in a flat state, the lifting means 60 is operated, the cutter 40 is lowered, and all the cutting blades 41 arranged in a straight line are placed on the packing sheet 10. Abut at a predetermined position. By pressing the cutting blade 41, the packing sheet 10 is cut, and the perforated openings 12 (each perforated line arranged in a straight line) shown in FIG. 3B are formed.
When the cutter 40 is lowered, an end perforation hole 52S is formed at a portion where the end cutting blade 41S abuts, and an end perforation hole 52E is formed at a portion where the end cutting blade 41E abuts. Is done. Further, each of the cutting blades 41 disposed between the end cutting blade 41S and the end cutting blade 41E, respectively, is disposed between the end perforation hole 52S and the end perforation hole 52E. A perforation is formed.

ミシン目開口部１２に形成されたミシン目のなかでは、端部ミシン目穴５２Ｓ，５２Ｅが最も穴長さが短く形成されている。また、他のミシン目穴は、端部ミシン目穴５２Ｓ，５２Ｅの各隣に配置されたものから、ミシン目開口部１２の延設方向中央に配置されたものにかけて、徐々に穴長さが長く形成され、上記のミシン目開口部１２の中央に配置されたミシン目穴が最も長い穴長さに形成されている。
なお、カッター４０によって形成されるミシン目開口部１２の直線状に並んだ各ミシン目穴は、前述のカッター２０によって形成されたものと同様な大きさ（穴長さ）を有し、また、同様な間隔をもって形成されている。 Among the perforations formed in the perforation opening 12, the end perforation holes 52S and 52E are formed with the shortest hole length. The other perforation holes gradually become longer from those arranged next to the end perforation holes 52S and 52E to those arranged in the center of the perforation opening 12 in the extending direction. The perforation hole formed in the center of the perforation opening 12 is formed to have the longest hole length.
Each perforation hole arranged in a straight line in the perforation opening 12 formed by the cutter 40 has the same size (hole length) as that formed by the cutter 20 described above, and They are formed at similar intervals.

梱包シート１０に、カッター４０を用いてミシン目開口部１２を形成させた後、当該梱包シート１０を、前述のティッシュペーパー束１１に覆い被せ、当該梱包シート１０の各端部を移動させてティッシュペーパー束１１を梱包する。
この後、梱包シート１０の各端部（図１に示した接合部１３）を実施例１で説明したように接着固定して所定形状に整形し、例えば略箱状の梱包体１を形成させる。 After forming the perforation opening 12 in the packing sheet 10 using the cutter 40, the packing sheet 10 is covered with the tissue paper bundle 11, and each end of the packing sheet 10 is moved to move the tissue. Pack the paper bundle 11.
Then, each edge part (joint part 13 shown in FIG. 1) of the packing sheet 10 is bonded and fixed as described in the first embodiment and shaped into a predetermined shape, for example, to form a substantially box-shaped packing body 1. .

実施例１および実施例２で説明したように、ミシン目開口部１２の両端に配置されるミシン目穴を短く形成し、中央に配置されるミシン目穴を長く形成したので、ミシン目開口部１２を開封する際に、大きな力を加えて梱包体１を押さえていなくとも、ミシン目に沿って容易に開封することが可能になる。   As described in the first and second embodiments, the perforation holes arranged at both ends of the perforation opening 12 are formed short, and the perforation holes arranged in the center are formed long. Even when the packaging body 1 is not pressed by applying a great force when opening 12, it can be easily opened along the perforation.

また、上記のように、ミシン目開口部１２の端部においてミシン目穴を短く、また中央においてミシン目穴を長く形成することにより、容易に開封することが可能になることから、隣り合うミシン目穴の間隔を適度に設け、ミシン目穴とミシン目穴の間の部分に適当な強度を備えるように構成することも可能になり、不意に上記のミシン目穴間が破れて開封されてしまうことを抑制し、内包された薄葉紙（ティッシュペーパーなど）を保護して汚れの付着や損傷を有効に防ぐことができる。   In addition, as described above, since the perforation hole is short at the end of the perforation opening 12 and the perforation hole is long at the center, it can be easily opened. It is also possible to provide a suitable space between the perforation holes and provide appropriate strength between the perforation holes, and the above perforation holes are unexpectedly broken and opened. And can protect the thin paper (such as tissue paper) contained therein and effectively prevent the adhesion and damage of dirt.

また、ミシン目開口部１２の両端に配置されるミシン目穴を短く、中央に配置されるミシン目穴を長く形成するとき、各ミシン目穴長さに応じた刃渡りの各切込刃２１を備えたカッター２１、または、各ミシン目穴長さに応じた刃渡りの各切込刃４１を備えたカッター４０を用いているので、開封を容易にした構成の梱包体１を比較的安価に、コストを抑制して製造することができる。   Further, when the perforation hole disposed at both ends of the perforation opening 12 is short and the perforation hole disposed at the center is formed long, each cutting blade 21 with a blade span corresponding to each perforation hole length is formed. Since the cutter 21 provided with each cutter blade 41 provided with the cutter 21 provided or each perforation length according to each perforation hole length is used, the package 1 with a configuration that facilitates opening is relatively inexpensive. It can be manufactured with reduced costs.
