Description

本発明は、梱包ケースに関し、例えば複数冊のカットシート等を梱包するための梱包ケースに関する。 The present invention relates to a packing case, for example, a packing case for packing a plurality of cut sheets and the like.

一般に、物流においては、商品・製品が箱に梱包されて運搬されることが多い。例えば、紙製品に関し、複写紙、印刷用紙、転写用紙、感圧紙、プリンタ用紙等のカットシートの流通は、カットシートを所定枚数単位で包装用紙に包装して形成された冊を、所定の冊数単位で梱包する段ボールや厚板紙製の梱包ケースを用いて行われている。 Generally, in logistics, goods and products are often packed in boxes and transported. For example, regarding paper products, in the distribution of cut sheets such as copy paper, printing paper, transfer paper, pressure sensitive paper, and printer paper, a predetermined number of books are formed by wrapping the cut sheets in a wrapping paper in units of a predetermined number of sheets. It is carried out using a packing case made of cardboard or thick paperboard that is packed in units.

従来、このような梱包ケースとして、展開状態において縦折れ線を介して横方向に連接している正面パネルと底面パネルと背面パネルと天面パネルと、正面パネルと背面パネルのそれぞれ縦方向の両端部に横折れ線を介して連接している内側面パネルと、底面パネルと天面パネルのそれぞれ縦方向の両端部に横折れ線を介して連接され内側面パネルの外側に重ねられて接着される外側面パネルと、天面パネルに縦折れ線を介して連接され正面パネルに接着される糊付けフラップとを有し、正面パネルと背面パネルに連接している内側面パネルには、天面パネルに連接している外側面パネルが重ねられる領域の一部に、ミシン目又はスリットからなる切り込み線で囲まれた側面切り取り部が設けられ、天面パネルに連接している外側面パネルと接着される内側面パネルの接着部は、側面切り取り部上に設けられており、また、正面パネルには、天面パネルに連接している糊付けフラップが重ねられる領域の一部に、ミシン目又はスリットからなる切り込み線で囲まれた正面切り取り部が設けられている梱包ケースが知られている（例えば、特許文献１。）。 Conventionally, as such a packing case, the front panel, the bottom panel, the back panel, and the top panel, which are connected in the horizontal direction via a vertical polygonal line in the unfolded state, and both ends of the front panel and the back panel in the vertical direction, respectively. The inner side panel, which is connected via a horizontal polygonal line, and the outer surface, which is connected to both ends of the bottom panel and top panel in the vertical direction via a horizontal polygonal line, are overlapped and adhered to the outside of the inner side panel. It has a panel and a glued flap that is connected to the top panel via a vertical polygonal line and adheres to the front panel, and the inner side panel that is connected to the front panel and the back panel is connected to the top panel. A side cutout surrounded by a cut line consisting of a perforation or a slit is provided in a part of the area where the outer side panels are overlapped, and the inner side panel is adhered to the outer side panel connected to the top panel. The adhesive portion is provided on the side cut portion, and the front panel has a cut line consisting of a perforation or a slit in a part of the area where the glue flap connected to the top panel is overlapped. A packing case provided with an enclosed front cutout is known (for example, Patent Document 1).

特許文献１に記載されているような梱包ケースは、開封に際し、天面パネルに連接され正面パネルに接着される糊付けフラップを、その開放端縁から剥離方向へ引き上げ、正面切り取り部を越えて接着している接着部の部分を剥離し、正面切り取り部を切り込み線から切断することにより正面パネルと糊付けフラップを分離し、そして、天面パネルの両端部に連接している外側面パネルを、その開放側端縁から剥離方向へ引き上げ、側面切り取り部を越えて接着している接着部の部分を剥離し、側面切り取り部を切り込み線から切断することにより外側面パネルと内側面パネルを分離する。 When opening a packaging case as described in Patent Document 1, the glued flap that is connected to the top panel and adhered to the front panel is pulled up from its open edge in the peeling direction and adhered beyond the front cutout portion. The front panel and the glued flap are separated by peeling off the part of the adhesive part that is attached and cutting the front cut part from the cut line, and the outer surface panel that is connected to both ends of the top surface panel is attached. The outer side panel and the inner side panel are separated by pulling up from the open side edge in the peeling direction, peeling off the adhesive portion that is adhered beyond the side cut portion, and cutting the side cut portion from the cut line.

正面パネルと糊付けフラップの分離及び外側面パネルと内側面パネルの分離に際し、正面パネルと糊付けフラップの剥離及び外側面パネルと内側面パネルの剥離にあっては、正面切り取り部及び側面切り取り部を越えて接着している接着部の部分だけであるため、剥離に要する力は僅かで済み、また、正面切り取り部及び側面切り取り部を囲んでいるミシン目又はスリットからなる切り込み線は軽い力で切断でき、正面切り取り部を正面パネルから切り取り、側面切り取り部を内側面パネルから切り取ることができるので、大きな力を必要とせず、正面パネルと糊付けフラップを分離し、外側面パネルと内側面パネルを分離することができ、開封作業が容易である。 When separating the front panel and the glued flap, and when separating the outer surface panel and the inner side panel, the peeling of the front panel and the glued flap and the peeling of the outer surface panel and the inner side panel go beyond the front cut portion and the side cut portion. Since it is only the part of the adhesive part that is glued together, the force required for peeling is small, and the cut line consisting of the perforations or slits surrounding the front cut part and the side cut part can be cut with a light force. Since the front cut part can be cut from the front panel and the side cut part can be cut from the inner side panel, the front panel and the glued flap are separated, and the outer side panel and the inner side panel are separated without requiring a large force. It can be opened and the opening work is easy.

カットシートを梱包した梱包ケースは、一般的に複数段に縦積みされて保管又は流通されるので、下段の梱包ケースは上段の梱包ケースからの荷重を受け続ける状態におかれる。そのため、下段に置かれた梱包ケースは、上段にある梱包ケースの荷重を受けて箱潰れし、また破損してしまい、梱包ケースの箱潰れや破損により、梱包されているカットシートが損傷してしまうといったおそれがある。また、カットシートに損傷が生じなくとも、箱潰れ・破損した梱包ケースは見栄えが悪く商品として好ましいとはいえない。そのため梱包ケースの強度はできるだけ高いことが望まれる。特に、梱包ケースにあって、側面部は外側面パネルと内側面パネルとで構成されているので、正面パネルのみ構成された正面部や背面パネルのみで構成された背面部に比べ上方からの荷重に弱い。 Since the packing case in which the cut sheet is packed is generally stacked vertically in a plurality of stages and stored or distributed, the lower packing case is kept in a state of being continuously subjected to the load from the upper packing case. Therefore, the packing case placed in the lower tier is crushed and damaged by the load of the packing case in the upper tier, and the packed cut sheet is damaged by the crushing or damage of the packing case. There is a risk that it will end up. Further, even if the cut sheet is not damaged, the crushed or damaged packing case does not look good and is not preferable as a product. Therefore, it is desirable that the strength of the packing case is as high as possible. In particular, in the packaging case, since the side surface portion is composed of the outer surface panel and the inner side surface panel, the load from above is compared with the front portion composed of only the front panel and the back portion composed of only the back panel. Weak to.

特許文献１に記載の梱包ケースは、開封を容易にするために側面部を構成する内側面パネルにミシン目又はスリットからなる切り込み線で囲まれて形成された側面切り取り部が設けられているので、側面切り取り部が設けられている内側面パネルの強度は弱く、側面部の強度の低下を招き、上方からの大きい荷重を受けたとき、梱包ケースに箱潰れや破損が生じるおそれがあるといった問題があった。 The packaging case described in Patent Document 1 is provided with a side cut portion formed by being surrounded by a notch line consisting of a perforation or a slit on an inner side panel constituting the side portion in order to facilitate opening. , The strength of the inner side panel provided with the side cutout is weak, which causes a decrease in the strength of the side surface, and when a large load is applied from above, the packing case may be crushed or damaged. was there.

本発明の目的は、開封を容易にしながら強度の低下を抑えて、箱潰れや破損が生じ難い梱包ケースを提供することにある。 An object of the present invention is to provide a packing case that is less likely to be crushed or damaged by suppressing a decrease in strength while facilitating opening.

切り取り部４４の形状や数に合っては特に限定されないが、上方からの荷重を分散させるといった点から、長方形の短辺側を円弧状にした形状を含む略楕円形であることが好ましい。本例では、切り取り部４４は、組立状態において正面パネル７で形成される正面部４３の側辺となる横折れ罫線８，９に対して傾斜し、その底面パネル６で形成される底面部４０側の端部Ａがそれぞれ外側に向くように形成されている（図４参照。）。 The shape and number of the cutout portions 44 are not particularly limited, but from the viewpoint of distributing the load from above, a substantially elliptical shape including a shape in which the short side of the rectangle is arcuate is preferable. In this example, the cut-out portion 44 is inclined with respect to the horizontal folding ruled lines 8 and 9 which are the side sides of the front portion 43 formed by the front panel 7 in the assembled state, and the bottom portion 40 formed by the bottom panel 6 thereof. The side ends A are formed so as to face outward (see FIG. 4).

なお、本例では天面パネル４に連接している糊付けフラップ２５の内面と接着される第３接着部分４２となる位置に、正面パネル７の外面にミシン目又はスリットからなる切り込み線４３で囲まれた切り取り部４４が設けられてるが、切り取り部４４ではなく、ハーフカット線で囲まれた層間切り取り面部を設けてもよい。 In this example, the outer surface of the front panel 7 is surrounded by a notch line 43 formed of a perforation or a slit at a position where the third adhesive portion 42 is bonded to the inner surface of the glued flap 25 connected to the top panel 4. Although the cut-out portion 44 is provided, an interlayer cut-out surface portion surrounded by a half-cut line may be provided instead of the cut-out portion 44.

また、本例では、底面パネル６に連接されている第２外側面パネル２２，２３には、正面パネルに連接されている第１内側面パネル１０，１１及び背面パネル５に連接されている第２内側面パネル１４，１５の外面と接着する第４糊代部４６が設けられており、第４糊代部４６には接着剤が塗布されている。 Further, in this example, the second outer surface panels 22 and 23 connected to the bottom panel 6 are connected to the first inner side surface panels 10 and 11 and the back panel 5 connected to the front panel. 2 A fourth glue margin portion 46 for adhering to the outer surfaces of the inner side surface panels 14 and 15 is provided, and an adhesive is applied to the fourth glue margin portion 46.

このような展開構造を有する本例では、縦折線１，２，３から天面パネル４、背面パネル５、底面パネル６、正面パネル７、糊付けフラップ２５がそれぞれ谷折りされ、糊付けフラップ２５が正面パネル７の開放端縁側の外面に接着されてケース本体４７が形成される。 In this example having such an unfolding structure, the top panel 4, the back panel 5, the bottom panel 6, the front panel 7, and the glue flap 25 are each valley-folded from the vertical folding lines 1, 2, and 3, and the glue flap 25 is the front. The case body 47 is formed by being adhered to the outer surface of the panel 7 on the open edge side.

この状態でカットシートがケース本体４７に収容されており、次に、横折れ罫線８，９から第１内側面パネル１０，１１が谷折りされ、また、横折れ罫線１２，１３から第２内側面パネル１４，１５が谷折りされて、更に、横折れ罫線２０，２１から第２外側面パネル２２，２３が谷折りされて第１内側面パネル１０，１１、第２内側面パネル１４，１５の上に重ねられて接着され、また、横折れ罫線１６，１７から第１外側面パネル１８，１９が谷折りされて第１内側面パネル１０，１１、第２内側面パネル１４，１５の上に重ねられて接着されることにより、開口部が封止され、これによって、カットシートが梱包された梱包ケースの組み立てが完成する（図４参照。）。 In this state, the cut sheet is housed in the case body 47, then the first inner side surface panels 10 and 11 are valley-folded from the horizontal fold ruled lines 8 and 9, and the horizontal fold ruled lines 12 and 13 to the second inner. The side panels 14 and 15 are valley-folded, and the second outer surface panels 22 and 23 are valley-folded from the horizontal fold ruled lines 20 and 21, and the first inner side panels 10 and 11 and the second inner side panels 14 and 15 are folded. The first outer surface panels 18 and 19 are valley-folded from the horizontal fold ruled lines 16 and 17 so as to be overlapped and adhered onto the first inner side panels 10 and 11 and the second inner side panels 14 and 15. The openings are sealed by being stacked and glued together, thereby completing the assembly of the packing case in which the cut sheet is packed (see FIG. 4).

このようにして封止された梱包ケースの開封にあっては、正面パネル７の開放端縁側の外面に接着されている糊付けフラップ２５を、糊付けフラップ２５の開放端縁から剥離方向に引き上げることにより、切り込み線４３を切断して切り込み線４３で囲まれた切り取り部４４を正面パネル７から切り取り、同時に切り取り部４４を越えている第３接着部分における糊付けフラップ２５と正面パネル７を剥離させる。これにより、糊付けフラップ２５と正面パネル７とが分離する。 When opening the packaging case sealed in this way, the glued flap 25 adhered to the outer surface of the front panel 7 on the open end edge side is pulled up from the open end edge of the glued flap 25 in the peeling direction. , The cut line 43 is cut and the cut portion 44 surrounded by the cut line 43 is cut from the front panel 7, and at the same time, the glued flap 25 and the front panel 7 at the third adhesive portion beyond the cut portion 44 are peeled off. As a result, the glued flap 25 and the front panel 7 are separated from each other.

また、第１内側面パネル１０、第２内側面パネル１４の外面に接着されている第１外側面パネル１８を、その解放側端縁から剥離方向に引き上げることにより、第１外側面パネル１８の内面に設けられている第１の層間切り取り面部３１及び第２の層間切り取り面部３５を第１外側面パネル１８から層間剥離させ、同時に第１の層間切り取り面部３１及び第２の層間切り取り面部３５を超えて接着している部分を剥離させる。これにより、第１外側面パネル１８と第１内側面パネル１０、第２内側面パネル１４とが分離する。 Further, by pulling up the first outer surface panel 18 adhered to the outer surfaces of the first inner side surface panel 10 and the second inner side surface panel 14 from the release side edge in the peeling direction, the first outer surface panel 18 The first interlayer cut surface portion 31 and the second interlayer cut surface portion 35 provided on the inner surface are delaminated from the first outer surface panel 18, and at the same time, the first interlayer cut surface portion 31 and the second interlayer cut surface portion 35 are separated from each other. Peel off the part that adheres beyond. As a result, the first outer surface panel 18, the first inner side surface panel 10, and the second inner side surface panel 14 are separated.

また、第１内側面パネル１１、第２内側面パネル１５の外面に接着されている第１外側面パネル１９を、その解放側端縁から剥離方向に引き上げることにより、第１外側面パネル１９の内面に設けられている第１の層間切り取り面部３２及び第２の層間切り取り面部３６を第１外側面パネル１９から層間剥離させ、同時に第１の層間切り取り面部３２及び第２の層間切り取り面部３６を超えて接着している部分を剥離させる。これにより、第１外側面パネル１９と第１内側面パネル１１、第２内側面パネル１５とが分離する。
このようにして、天面パネル４の三方が開放され、天面パネル４は背面パネル５との間の縦折れ罫線１をヒンジとしてケース本体４７の開口部が開口し、梱包ケースが開封される。 Further, by pulling up the first outer surface panel 19 adhered to the outer surfaces of the first inner side surface panel 11 and the second inner side surface panel 15 in the peeling direction from the release side edge thereof, the first outer surface panel 19 The first interlayer cut surface portion 32 and the second interlayer cut surface portion 36 provided on the inner surface are delaminated from the first outer surface panel 19, and at the same time, the first interlayer cut surface portion 32 and the second interlayer cut surface portion 36 are separated from each other. Peel off the part that adheres beyond. As a result, the first outer surface panel 19, the first inner side surface panel 11, and the second inner side surface panel 15 are separated.
In this way, the three sides of the top panel 4 are opened, the opening of the case body 47 of the top panel 4 is opened by using the vertically folded ruled line 1 between the top panel 4 and the back panel 5 as a hinge, and the packing case is opened. ..

このように構成された第１例の梱包ケースによれば、第１外側面パネル１８，１９の内面と第１内側面パネル１０，１１の外面との第１接着部分２６，２７において、第１外側面パネル１８，１９の内面に設けられた第１の層間切り取り面部３１，３２はハーフカット線３０で形成され、同様に、第１外側面パネル１８，１９の内面と第２内側面パネル１４，１５の外面との第２接着部分２８，２９において、第１外側面パネル１８，１９の内面に設けられた第２の層間切り取り面部３５，３６はハーフカット線３０で形成されているので、特許文献１に記載されているような、ミシン目又はスリットからなる切り込み線で形成された側面切り取り部が設けられている内側面パネルに比べ、第１外側面パネル１８，１９の強度は強く、上方からの荷重に対して容易に箱潰れや破損が生じない梱包ケースを得ることができる。 According to the packing case of the first example configured in this way, in the first adhesive portions 26 and 27 between the inner surfaces of the first outer surface panels 18 and 19 and the outer surfaces of the first inner surface panels 10 and 11, the first The first interlayer cut surface portions 31 and 32 provided on the inner surfaces of the outer side surface panels 18 and 19 are formed by the half-cut lines 30, and similarly, the inner surfaces of the first outer surface panels 18 and 19 and the second inner side surface panels 14 The second interlayer cut surface portions 35 and 36 provided on the inner surfaces of the first outer surface panels 18 and 19 are formed by the half-cut lines 30 in the second adhesive portions 28 and 29 with the outer surfaces of 15 and 15. The strength of the first outer surface panels 18 and 19 is stronger than that of the inner side panel provided with the side cut portion formed by the cut line formed by the perforation or the slit as described in Patent Document 1. It is possible to easily obtain a packaging case in which the box is not crushed or damaged by a load from above.

また、本例では、第１の層間切り取り面部３１，３２及び第２の層間切り取り面部３５，３６は、長方形の短辺側を円弧状にした形状を含む略楕円形に形成されているので、上方からの荷重を第１の層間切り取り面部３１，３２及び第２の層間切り取り面部３５，３６の周囲の一極に集中することなく円弧辺の部分で分散させることができ、箱潰れや破損を効果的に防止することができる。 Further, in this example, the first interlayer cut surface portions 31, 32 and the second interlayer cut surface portions 35, 36 are formed in a substantially elliptical shape including a shape in which the short side side of the rectangle is arcuate. The load from above can be distributed at the arc side without concentrating on one pole around the first interlayer cut surface portions 31, 32 and the second interlayer cut surface portions 35, 36, and the box can be crushed or damaged. It can be effectively prevented.

また、本例では、梱包ケースは、略楕円形に形成された第１の層間切り取り面部３１，３２及び第２の層間切り取り面部３５，３６は、組立状態において天面パネル４で形成される天面部３９の側辺に対して傾斜し、底面パネル６で形成される底面部４０側のそれぞれの端部が外側に向くように形成されているので、上方から荷重がかかった際、その荷重を外方向へ向かって分散させることができ、荷重による箱歪みや崩れ等の発生を効果的に防止することができる。 Further, in this example, in the packing case, the first interlayer cut surface portions 31, 32 and the second interlayer cut surface portions 35, 36 formed in a substantially elliptical shape are formed by the top panel 4 in the assembled state. Since the end portions on the bottom surface portion 40 side formed by the bottom surface panel 6 are formed so as to be inclined with respect to the side side of the surface portion 39, the load is applied when a load is applied from above. It can be dispersed in the outward direction, and it is possible to effectively prevent the occurrence of box distortion and collapse due to the load.

また、本例では、天面パネル４と糊付けフラップ２５を連接する縦折れ罫線２４上には、所定間隔でスリット４１が設けられているので、縦折れ罫線２４の部分の強度が弱く、上方から荷重がかかった際、縦折れ罫線２４の部分が変形して天面パネル４だけが沈み込むことで、天面パネル４に縦折れ罫線２４を介して連接されている糊付けフラップ２５が正面パネル７から剥離してしまうことを防止することができる。 Further, in this example, since slits 41 are provided at predetermined intervals on the vertical folding ruled line 24 connecting the top panel 4 and the glued flap 25, the strength of the vertical folding ruled line 24 is weak and is viewed from above. When a load is applied, the portion of the vertical fold ruled line 24 is deformed and only the top panel 4 sinks, so that the glued flap 25 connected to the top panel 4 via the vertical fold ruled line 24 is the front panel 7. It is possible to prevent it from peeling off from the surface.

また、梱包ケースの開封に際しては、第１外側面パネル１８，１９をその解放側端縁から剥離方向に引き上げることにより、第１の層間切り取り面部３１，３２及び第２の層間切り取り面部３５，３６を越えている接着部分を剥離し、ハーフカット線３０で囲まれた第１の層間切り取り面部３１，３２及び第２の層間切り取り面部３５，３６を層間剥離させて切り取るので、第１外側面パネル１８，１９と第１内側面パネル１０，１１及び第２内側面パネル１４，１５を大きな力を必要とすることなく分離することができ、開封作業を容易に行うことができる。 When opening the packing case, the first outer surface panels 18 and 19 are pulled up from the release side edge in the peeling direction, so that the first interlayer cut surface portions 31 and 32 and the second interlayer cut surface portions 35 and 36 are pulled up. The first interlayer cut surface portions 31, 32 and the second interlayer cut surface portions 35, 36 surrounded by the half cut line 30 are peeled off and cut off, so that the first outer surface panel 18, 19, the first inner side surface panels 10, 11 and the second inner side surface panels 14, 15 can be separated without requiring a large force, and the opening operation can be easily performed.

次に、本発明に係る梱包ケースの実施の形態の第２例を図面を参照して詳細に説明する。図５は本発明に係る梱包ケースの実施の形態の第２例を示す展開図である。
