Description

この発明は、供給される製品に対し包材を胴巻きして包装する包装方法及び包装袋に関する。   The present invention relates to a packaging method and a packaging bag in which a packaging material is wound around a product to be supplied.

従来、例えば土産物や弁当などの製品を包材で上包みする包装形態として、製品の外周面を胴巻きして、胴巻き包装袋を成形するものがある。一般に、胴巻き包装袋は、製品の側周面を包材で折り込み、底面において包材の両端部を重ね合わせて接着させたものが多い。すなわち、製品を筒状の包材で覆う構成である。このような胴巻き包装袋は、包材の使用量が少なくて済み、また包装装置の構造も複雑にならないため、製作コストや作業時間を軽減させることができる。しかしながら、この胴巻き包装袋は、筒状に折り込まれた包材であるため、軸方向に簡単にずれてしまう。   2. Description of the Related Art Conventionally, as a packaging form in which a product such as a souvenir or a lunch box is overwrapped with a packaging material, there is one that forms a body-wrapped packaging bag by winding the outer peripheral surface of the product. In general, many body-wrapped packaging bags are obtained by folding the side peripheral surface of a product with a packaging material and bonding the both ends of the packaging material on the bottom surface. That is, the product is covered with a cylindrical packaging material. Such a waist-wrapping bag requires a small amount of packaging material and does not complicate the structure of the packaging device, so that the manufacturing cost and work time can be reduced. However, since this waist-wrapping bag is a packaging material folded in a cylindrical shape, it is easily displaced in the axial direction.

以上のような問題点を解決するための包装方法として、特許文献１に開示された構成がある。特許文献１の発明は、包材シートの一方の端部が接着剤によって物品に付着され、他方の端部が接着剤によって一方の端部に付着される胴巻き包装体である。つまり、接着剤を包材シートの両端部に塗布して一方の端部を物品に接着させることで、包材シートのずれを防止している。
特開平１１−２６３３７１公報 As a packaging method for solving the above problems, there is a configuration disclosed in Patent Document 1. The invention of Patent Document 1 is a body-wrapped package in which one end of a packaging material sheet is attached to an article with an adhesive and the other end is attached to one end with an adhesive. In other words, the adhesive sheet is applied to both end portions of the packaging material sheet, and one end portion is adhered to the article, thereby preventing the packaging material sheet from shifting.
JP 11-263371 A

さて、特許文献１の胴巻き包装体を成形するには、包材の両端部に対して接着剤（以下、糊ともいう）を塗布しなければならない。それを従来の装置で実現するには、糊を塗布する装置を二つ設けた構造とするか、あるいは一つの糊塗布装置が包材の両端間を移動して糊を塗布する構造とする必要があった。いずれにしても、装置の構造が複雑になることは避けられず、包装時やメンテナンス時など作業全体に対し、コストや手間がかかる。   Now, in order to form the body-wrapped package of Patent Document 1, an adhesive (hereinafter also referred to as glue) must be applied to both ends of the packaging material. To achieve this with conventional devices, it is necessary to have a structure with two devices for applying glue, or a structure in which one glue applicator moves between both ends of the packaging material to apply glue. was there. In any case, it is inevitable that the structure of the apparatus becomes complicated, and costs and labor are required for the entire operation such as packaging and maintenance.

本発明は、このような事情に鑑みてなされたもので、包材に対し一部位にのみ糊を塗布するだけで、包材が製品からずれるおそれのない包装方法及び胴巻き包装袋を提供することにある。   The present invention has been made in view of such circumstances, and provides a packaging method and a waist-wrapping bag in which the packaging material is not likely to be displaced from the product only by applying the glue to the packaging material only partially. It is in.

上記目的を達成するために、本発明の方法は、帯状の包材の一端部に設定した接着領域に糊を塗布する糊塗布ステップと、
包材の中間部を製品の外周面に配置するとともに、糊が塗布されていない包材の他端部を製品の外周面に沿って一方側から折り込み、次いで糊が塗布された包材の一端部を製品の外周面に沿って他方側から折り込み、当該一端部を他端部に重ね合わせる胴巻きステップと、を有する包装方法であって、
接着領域が、さらに包材の他端部と重なり合って当該他端部を接着する包材接着領域と、当該他端部と重なり合わず製品の外周面に接着する製品接着領域とを含むことを特徴とする。 In order to achieve the above object, the method of the present invention includes a glue application step of applying glue to an adhesive region set at one end of a band-shaped packaging material;
Place the middle part of the packaging material on the outer peripheral surface of the product, fold the other end of the packaging material not coated with glue from one side along the outer peripheral surface of the product, and then one end of the packaging material coated with glue A body winding step of folding a part from the other side along the outer peripheral surface of the product and superimposing the one end part on the other end part,
The adhesive region further includes a packaging material adhesion region that overlaps the other end portion of the packaging material and adheres the other end portion, and a product adhesion region that adheres to the outer peripheral surface of the product without overlapping the other end portion. Features.

かかる方法によれば、製品接着領域が製品と接着することになり、製品に対し包材がずれることがない。さらに、胴巻き包装袋を成形する包材は、一端部に対してのみ糊を塗布することになる。したがって、糊を塗布する装置は一つで済むことになり、糊塗布ステップなどの包装工程が複雑化することもない。   According to such a method, the product adhesion region adheres to the product, and the packaging material does not deviate from the product. Furthermore, the packaging material for forming the body-wrapped packaging bag applies the glue only to one end portion. Therefore, only one apparatus for applying the glue is required, and the packaging process such as the glue applying step is not complicated.

また、本発明の包装方法は、製品接着領域が、包材の一端部と他端部との重合部分から包材長手方向にはみ出して形成される構成とすることができる。これにより、製品接着領域と包材接着領域が隣接することになる。よって、これら二つの領域にまたがって糊が塗布されるので、包材を製品に接着させ、かつ包材の両端部を接着させた胴巻き包装袋を成形することができる。   Moreover, the packaging method of this invention can be set as the structure which a product adhesion | attachment area | region protrudes in the packaging material longitudinal direction from the superposition | polymerization part of the one end part and other end part of a packaging material. Thereby, the product adhesion area and the packaging material adhesion area are adjacent to each other. Accordingly, since the glue is applied across these two regions, it is possible to form a body-wrapped packaging bag in which the packaging material is adhered to the product and both ends of the packaging material are adhered.

さらに、本発明の包装方法は、包材の他端部に開口部を形成しておき、包材の一端部を他端部に重ね合わせたとき、当該開口部に対向する接着領域により、製品接着領域が形成される構成としてもよい。包材の一端部の製品接着領域が包材の他端部の開口部を通して、直接製品に接着され、包材のずれを防止することができる。また、接着領域は上記の構成より狭くてもよく、塗布される糊の量を少なくすることもできる。   Furthermore, the packaging method of the present invention has an opening formed at the other end of the packaging material, and when one end of the packaging material is overlaid on the other end, the adhesive region facing the opening It is good also as a structure in which an adhesion | attachment area | region is formed. The product adhesion region at one end of the packaging material is directly adhered to the product through the opening at the other end of the packaging material, thereby preventing the packaging material from shifting. In addition, the adhesion region may be narrower than the above configuration, and the amount of glue applied can be reduced.

また、本発明の胴巻き包装袋は、次の（イ）乃至（ハ）の構成を有することを特徴とする。
（イ） 帯状の包材が製品の外周面に胴巻きされ、当該包材の一端部が他端部と重なり合っている。
（ロ） 前記包材の重なり合った一端部と他端部とが糊によって接着された包材接着領域を有する。
（ハ） 前記包材の一端部が、他端部と重なり合わずに、前記製品の外周面と糊によって接着された製品接着領域を有する。 The body-wrapped packaging bag of the present invention is characterized by having the following configurations (a) to (c).
(A) A band-shaped packaging material is wound around the outer peripheral surface of the product, and one end portion of the packaging material overlaps the other end portion.
(B) The packaging material has a packaging material adhesion region in which one end and the other end of the packaging material are adhered by glue.
(C) One end portion of the packaging material does not overlap the other end portion, and has a product adhesion region bonded to the outer peripheral surface of the product by glue.

かかる構成の胴巻き包装袋は、包材の一端部にのみ糊が塗布されることになり、効率的に包装作業を行うことができる。   The body-wrapped packaging bag having such a configuration is such that the paste is applied only to one end of the packaging material, and the packaging operation can be performed efficiently.

また、胴巻き包装袋は、製品接着領域が、包材の一端部と他端部との重合部分から包材長手方向にはみ出して形成される構成としてもよい。さらに、包材の他端部に開口部が形成されており、当該開口部を通して包材の一端部が製品の外周面と糊によって接着されることで、製品接着領域が形成される構成でもよい。   Further, the body-wrapping bag may have a structure in which the product adhesion region is formed so as to protrude from the overlapping portion of the one end portion and the other end portion of the packaging material in the packaging material longitudinal direction. Further, an opening may be formed at the other end of the packaging material, and one end of the packaging material may be bonded to the outer peripheral surface of the product with glue through the opening to form a product adhesion region. .

胴巻き包装袋は、包材の一端部であって製品接着領域内または製品接着領域の周囲にミシン目を形成し、包材を前記製品から剥がしたとき、ミシン目から切り離された包材の一端部が製品に接着したまま残存する構成とすることもできる。ミシン目によって包材が製品に接着したままになることで、一度包材が剥がされた製品の見分けが容易につくようになり、不正開封された製品を購買者に引き渡すことを防止できる。   The waist-wrapped bag is one end of the packaging material, and forms a perforation in or around the product adhesion region, and one end of the packaging material separated from the perforation when the packaging material is peeled off from the product. It is also possible to adopt a configuration in which the portion remains adhered to the product. Since the packaging material remains adhered to the product by the perforation, it becomes easy to distinguish the product once the packaging material has been peeled off, and it is possible to prevent the unopened product from being delivered to the purchaser.

以上説明したように、本発明の包装方法及び胴巻き包装袋は、包材に対し一部位にのみ糊を塗布するだけで、包材がずれずに製品を包装することができる。   As described above, the packaging method and the waist-wrapping bag of the present invention can wrap a product without shifting the packaging material only by applying the glue only to a part of the packaging material.

以下、この発明の実施の形態について図面を参照して詳細に説明する。
〔第１の実施形態〕
図１乃至図３は、第１の実施形態に係る包装方法を示す図であり、図１は、製品の包装手順を示した概略図である。
図１に示すように、第１の実施形態の包装方法は、糊塗布ステップ１、胴巻きステップ２の順に包装する包装工程を備えている。製品３はこの包装工程を備えた包装装置に供給されて各ステップを通過することで包装される。なお、本実施形態において包装される製品３は、例えば、土産物を収容する箱形容器などが該当する。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[First Embodiment]
1 to 3 are diagrams showing a packaging method according to the first embodiment, and FIG. 1 is a schematic diagram showing a product packaging procedure.
As shown in FIG. 1, the packaging method of the first embodiment includes a packaging process of packaging in the order of glue application step 1 and body winding step 2. The product 3 is supplied to the packaging apparatus provided with this packaging process, and is packaged by passing through each step. In addition, the product 3 packaged in the present embodiment corresponds to, for example, a box-shaped container that stores a souvenir.

まず、包装装置の包装工程について説明すると、包材４は、ちょうど製品３を胴巻きにして重ね合わせることが可能な寸法に切断されて、糊塗布ステップ１に供給される。包装装置の糊塗布ステップ１では、この切断された帯状の包材４の一端部４１に対し、包装装置に設けられた糊塗布装置１０が対向してあり、包材４の移動とともに糊塗布装置１０から糊が噴霧され、下面に設定した接着領域４２に対して糊が塗布される。そして、糊が塗布された包材４は、胴巻きステップ２に搬送される。   First, the packaging process of the packaging apparatus will be described. The packaging material 4 is cut into dimensions that can be overlapped with the product 3 just as a body, and supplied to the glue application step 1. In the glue application step 1 of the packaging device, the glue application device 10 provided in the packaging device is opposed to the one end portion 41 of the cut strip-like packaging material 4, and the glue application device is moved along with the movement of the packaging material 4. The glue is sprayed from 10, and the glue is applied to the adhesive region 42 set on the lower surface. Then, the packaging material 4 to which the paste is applied is conveyed to the body winding step 2.

包装装置の胴巻きステップ２では、包材４が供給される位置に対し、製品３が下方から搬送されてくる。さらに、製品３は包材４とともに上方に押し上げられることで、包材４が製品３の上面及び側面に胴折りされる。このようにして、胴折りされた包材４及び製品３は、下面に延在する包材４の両端部が図示しない折り込み機構によって内側に折り込まれる。この両端部の折り込みは、糊が塗布されていない包材４の他端部４３を製品３の外周面に沿って一方側から折り込み、次いで糊が塗布された包材４の一端部４１を製品３の外周面に沿って他方側から折り込み、この一端部４１を他端部４３に重ね合わせることでことで、胴巻き包装袋が成形される。   In the body winding step 2 of the packaging device, the product 3 is conveyed from below to the position where the packaging material 4 is supplied. Furthermore, the product 3 is pushed upward together with the packaging material 4, so that the packaging material 4 is folded to the upper surface and the side surface of the product 3. In this way, the packaging material 4 and the product 3 which are folded into the body are folded inward by a folding mechanism (not shown) at both ends of the packaging material 4 extending to the lower surface. The folding of the both ends is performed by folding the other end 43 of the packaging material 4 to which the glue is not applied from one side along the outer peripheral surface of the product 3 and then the one end 41 of the packaging material 4 to which the glue is applied to the product. 3 is folded from the other side along the outer peripheral surface 3 and the one end portion 41 is overlapped with the other end portion 43 to form a body-wrapped packaging bag.

図２は、第１の実施形態に係る包装方法の糊塗布装置の構成を示す図であり、（ａ）は正面図、（ｂ）は拡大側面断面図であり、図３は、同じく包装方法によって成形される胴巻き包装袋を示す図であり、（ａ）は下面から見た斜視図、（ｂ）は包材のみの底面図、（ｃ）は側面概略図である。
図２に示すように、糊塗布ステップ１の糊塗布装置１０は、先端部１２のノズル孔１３から糊を噴射する構成である。糊塗布装置１０は、内部の中空部１４に糊が供給されて、この中空部１４に備えられたニードル１５の上下摺動によって糊が吐出される。 2A and 2B are diagrams showing the configuration of the paste applying apparatus of the packaging method according to the first embodiment, wherein FIG. 2A is a front view, FIG. 2B is an enlarged side sectional view, and FIG. It is a figure which shows the trunk-wrapping packaging bag shape | molded by this, (a) is the perspective view seen from the lower surface, (b) is a bottom view of only a packaging material, (c) is a schematic side view.
As shown in FIG. 2, the glue application device 10 in the glue application step 1 is configured to inject glue from the nozzle hole 13 of the distal end portion 12. In the glue applying device 10, the glue is supplied to the hollow part 14 inside, and the glue is discharged by sliding the needle 15 provided in the hollow part 14 up and down.

また、糊塗布装置１０は、ノズル孔１３の周囲から気体が噴射される気体供給手段１６が備えられている。気体供給手段１６は、外部の図示しない供給源から気体を糊塗布装置１０に供給し、中空部１４の周囲の気体流路１７を通過させて、先端部１２から気体を噴射させる構成である。この気体の噴射は、一定の収束角をもって噴射させ、ノズル孔１３の周囲が負圧となるように形成されている。したがって、ノズル孔１３から吐出される糊は、負圧の作用をもって吸い出されて噴射され、気体にのって対向する包材４に幅広に塗布される。   Further, the glue applying device 10 is provided with a gas supply means 16 for injecting gas from the periphery of the nozzle hole 13. The gas supply means 16 is configured to supply a gas from an external supply source (not shown) to the glue application device 10 and to pass the gas flow path 17 around the hollow portion 14 and to inject the gas from the tip portion 12. The gas is injected with a constant convergence angle so that the periphery of the nozzle hole 13 has a negative pressure. Therefore, the paste discharged from the nozzle hole 13 is sucked out and sprayed with the action of negative pressure, and is applied in a wide manner on the facing packaging material 4 on the gas.

図３（ｂ）に示すように、糊塗布装置１０から噴射された糊は、包材４の一端部４１に塗布されて接着領域４２を形成する。糊は、包材４の移動中に噴射されることによって、接着領域４２に帯状に塗布される。また、本実施形態の糊の接着領域４２は、包材４の他端部４３と重なり合ってこの他端部４３を接着する包材接着領域４２ａと、他端部４３と重なり合わず製品３の外周面に接着する製品接着領域４２ｂとを含む構成である。したがって、糊の接着領域４２は、比較的幅広となることが好ましく、本実施形態では、気体とともに糊を広角に噴射する糊塗布装置１０を適用することで実現している。   As shown in FIG. 3 (b), the glue sprayed from the glue application device 10 is applied to one end 41 of the packaging material 4 to form an adhesive region 42. The glue is applied to the adhesive region 42 in a band shape by being sprayed during the movement of the packaging material 4. Further, the adhesive bonding area 42 of the present embodiment overlaps with the other end portion 43 of the packaging material 4 and adheres to the other end portion 43, and the other end portion 43 does not overlap with the other end portion 43 of the product 3. And a product adhesion region 42b that adheres to the outer peripheral surface. Therefore, it is preferable that the adhesive bonding region 42 is relatively wide. In the present embodiment, this is realized by applying the glue applying device 10 that injects the glue together with the gas at a wide angle.

以上のようにして糊が塗布された包材４は、胴巻きステップ２において胴折りされて、製品３の外周面に胴巻きされる。図３（ａ）、（ｃ）に示すように、包材４は、糊が塗布されていない他端部４３が下に、糊が塗布された一端部４１が上になって重なり合い、胴巻き包装袋が成形される。この胴巻き包装袋は、包材接着領域４２ａが重なり合った一端部４１と他端部４３とによって形成され、製品接着領域４２ｂが包材４の一端部４１と他端部４３との重合部分から包材長手方向にはみ出して形成されることになる。すなわち、接着領域４２は、包材接着領域４２ａと製品接着領域４２ｂによって、包材４の両端部の接着と、包材４と製品３とを同時に接着することになる。   The packaging material 4 to which the paste has been applied as described above is subjected to body folding in the body winding step 2 and is wound onto the outer peripheral surface of the product 3. As shown in FIGS. 3 (a) and 3 (c), the wrapping material 4 overlaps with the other end portion 43, to which no glue is applied, facing down, and the one end portion 41, to which glue is applied, facing up. A bag is formed. This body-wrapping bag is formed by one end 41 and the other end 43 where the packaging material bonding regions 42 a overlap each other, and the product bonding region 42 b is wrapped from the overlapping portion of the one end 41 and the other end 43 of the packaging material 4. It is formed so as to protrude in the longitudinal direction of the material. In other words, the bonding area 42 bonds the both ends of the packaging material 4 and the packaging material 4 and the product 3 simultaneously by the packaging material bonding area 42a and the product bonding area 42b.

このようにして成形された胴巻き包装袋は、包材４が製品３に接着していることにより、包材４のずれが生じない。また、包装工程上では、包材４の一端部４１に対してのみ糊を塗布する構成であり、包装装置は全体として構造や動作が複雑化することがない。   In the body-wrapped packaging bag formed in this manner, the packaging material 4 is bonded to the product 3, so that the packaging material 4 is not displaced. Further, in the packaging process, the paste is applied only to the one end portion 41 of the packaging material 4, and the structure and operation of the packaging device as a whole are not complicated.

次に、本発明の第２の実施形態について説明する。
〔第２の実施形態〕
図４は、本発明の第２の実施形態に係る包装方法を示す概略図である。なお、以降の実施形態に係る包装方法において、先に示した第１の実施形態に係る包装方法と同一部分または相当する部分には、同一符号を付しその部分の詳細な説明は省略する。 Next, a second embodiment of the present invention will be described.
[Second Embodiment]
FIG. 4 is a schematic view showing a packaging method according to the second embodiment of the present invention. In the packaging methods according to the following embodiments, the same or corresponding parts as those in the packaging method according to the first embodiment described above are denoted by the same reference numerals, and detailed description thereof is omitted.

図４（ａ）に示すように、第２の実施形態の包材４は、糊が塗布されない他端部４３に二つの開口部４４が形成されている。これら開口部４４は、包材４の一端部４１を他端部４３に重ね合わせたとき、開口部４４に対向する接着領域４２により、製品接着領域４２ｂが形成される。また、包材４の一端部４１には、製品接着領域４２ｂ内またはその周囲にミシン目４５が形成されている。このミシン目４５は、包材４の両端部を重ね合わせたときに、他端部４３の開口部４４と対向する位置に配置される構成である（図４（ｃ）参照）。   As shown in FIG. 4A, the packaging material 4 of the second embodiment has two openings 44 formed at the other end 43 where no glue is applied. When the one end 41 of the packaging material 4 is overlapped with the other end 43, the opening 44 forms a product bonding region 42b by the bonding region 42 facing the opening 44. Further, a perforation 45 is formed in one end portion 41 of the packaging material 4 in or around the product adhesion region 42b. This perforation 45 is a structure arrange | positioned in the position facing the opening part 44 of the other end part 43 when the both ends of the packaging material 4 are piled up (refer FIG.4 (c)).

本実施形態の胴巻き包装袋の成形工程について説明すると、まず糊塗布ステップ１において、包材４の一端部４１に糊が塗布され接着領域４２が形成される。その後、胴巻きステップ２において、図４（ａ）に示すように、製品３の胴部の中心に包材４が配置される。この包材４の胴折りは、図４（ｂ）に示すように、先に開口部４４を有した他端部４３が製品３の外周面に折り込まれる。   The forming process of the body-wrapping bag according to this embodiment will be described. First, in the paste application step 1, the adhesive is applied to one end portion 41 of the packaging material 4 to form an adhesive region 42. Thereafter, in the body winding step 2, the packaging material 4 is arranged at the center of the body portion of the product 3 as shown in FIG. As shown in FIG. 4 (b), the other end portion 43 having the opening 44 is folded at the outer peripheral surface of the product 3 in the body folding of the packaging material 4.

さらに、図４（ｃ）に示すように、糊が塗布された包材４の一端部４１が胴折りされ、他端部４３に重ね合わされる。このとき、一端部４１の接着領域４２は、ちょうど他端部４３の開口部４４に重ね合わされることになる。すなわち、接着領域４２は、包材接着領域４２ａが他端部４３と接着するとともに、製品接着領域４２ｂが開口部４４から露出する製品３の外周面に接着する。これにより、第２の実施形態の胴巻き包装袋は、第１の実施形態と同じく、包材４のずれが生じることがなくなる。   Further, as shown in FIG. 4C, one end 41 of the packaging material 4 to which the paste is applied is body-folded and overlapped with the other end 43. At this time, the bonding region 42 of the one end portion 41 is just overlapped with the opening 44 of the other end portion 43. That is, the bonding region 42 is bonded to the outer peripheral surface of the product 3 where the packaging material bonding region 42 a is bonded to the other end portion 43 and the product bonding region 42 b is exposed from the opening 44. Thereby, as for the trunk-wrapping packaging bag of 2nd Embodiment, the shift | offset | difference of the packaging material 4 does not arise like 1st Embodiment.

また、図４（ｄ）に示すように、包材４を製品３から剥がすときは、ミシン目４５内の包材一端部４５ａがミシン目４５から切り離されて製品３に接着したまま残存する構成である。このため、一度包材４が剥がされた製品３の見分けが容易につくようになり、不正開封された製品３を購買者に引き渡すことを防止できる。   Also, as shown in FIG. 4D, when the packaging material 4 is peeled off from the product 3, the packaging material one end 45 a in the perforation 45 is separated from the perforation 45 and remains attached to the product 3. It is. For this reason, the product 3 from which the packaging material 4 has been peeled once can be easily identified, and the product 3 that has been tampered with can be prevented from being delivered to the purchaser.

以上、第２の実施形態の包装方法によれば、第１の実施形態と同様に、包材４の一端部４１に対してのみ糊を塗布する構成であり、包装装置は構造や動作が複雑化することがない。また、他端部４３の開口部４４が製品接着領域４２ｂを形成させることによって、糊が塗布される接着領域４２の幅寸法が第１の実施形態よりも狭くてもよく、糊の使用量を少なくさせることができる。
なお、本発明の包装方法は、上述した第１、第２の実施形態に限定されるものではなく、種々の変形例や応用例をもって構成することも可能である。例えば、ミシン目４５は第２実施形態の開口部４４に対向する包材４の一端部４１に対して適用されるだけではなく、第１の実施形態の製品接着領域４２ｂに対して形成してもよい。
