JP6441602B2 - Packaging box and its blank sheet - Google Patents

Description

  The present invention relates to a packaging box for storing articles and a blank sheet thereof, and particularly to a packaging box in which a cut line serving as a hand hole for transportation is formed on a side wall and the blank sheet thereof.

  Conventionally, corrugated packaging boxes (cardboard boxes) in which a plurality of beverage bottles are packed are widely distributed. This packaging box is transported under various circumstances, such as being carried by a purchaser who bought the box, as well as transporting goods during transportation.

  In order to make the packaging box easy to carry, the both side walls of the packaging box are provided with cut lines serving as hand holes for carrying. The cut line to be a hand hole is formed at a position slightly lower than the upper end of both side walls of the packaging box. When carrying, the user pushes the area (piece) surrounded by the cut line into the box with his / her finger. If it does so, the hand hole which is an opening which can penetrate a finger | toe inside a box will be formed in the side wall of a box.

  The user can carry the packaging box in a suspended state by inserting a finger into the hand hole and grasping the side wall above the hand hole.

  However, when the contents of the box are heavy, when it is lifted vigorously, or when it is held with one hand using only one hand hole instead of using both hand holes on both sides, There are the following inconveniences. That is, when the side wall on the hand hole is gripped, a large load is applied to the upper end of the hand hole. Then, a side wall will be torn from the edge part etc. of the cut line in a hand hole upper end. Such damage to the hand hole hinders carrying such as dropping the package. Further, there is a problem that the hand hole portion is greatly opened due to tearing, and foreign matters and insects are easily mixed. Furthermore, the appearance of the box becomes dirty due to the tearing of the box, causing a reduction in the commercial value.

  In Patent Document 1, a first cut line extending downward from two spaced points on the side wall of the box, and a corner (score) of the side wall and the top plate from the upper ends of a pair of side lines of the first cut line. What provided the extended 2nd score line is disclosed.

  In the technique disclosed in Patent Document 1, when carrying holes (hand holes) are formed, the first cut line is bent into the box, and then the second cut line is pivoted on the corners of the side wall and the top plate. As shown in FIG. That is, a handle portion bent into a triangular prism shape or the like is formed in a transport hole (hand hole) portion by a two-stage folding operation to facilitate carrying.

JP 2013-203472 A

  However, the handle part in the hand hole described in Patent Document 1 requires a two-stage folding operation until it is formed, and there is a problem that the speed of carrying the box is lacking.

  Moreover, in order to form a hand hole, the space which pushes in the piece enclosed with a cut line is needed inside a box. For example, when the contents of the box are plastic bottles, the bottle body is a substantially rectangular parallelepiped, and therefore comes into contact with the side wall. Therefore, in order to pack the PET bottles inside the box without gaps and to be able to form a hand hole, as the space to push the piece, use the space created by the slanted part from the bottle mouth to the shoulder It will be. In the conventional hand hole formed at the lower side from the upper end of both side walls and the hand hole described in Patent Document 1, the cut line is located at the lower side from the upper end of the side wall. Here, when the position of the shoulder of the bottle is high, the space from the top plate to the bottle body is small, so the height of the previous piece pushing space cannot be gained. On the other hand, since the conventional cut line is located at a position that is lowered from the upper end of the side wall, in the case of a bottle with a high shoulder position, there is a possibility that a piece to be pushed hits the bottle body. Therefore, in the case of the conventional hand hole forming portion, there is a problem that the space inside the box where the piece and the handle portion can enter is required to some extent, and the shape of the contents is limited.

  In addition, a triangular prism-shaped handle or a plate-shaped handle has one side of the handle in contact with the abdomen of the finger in a line, and the user's hand is in a state where the load during carrying is concentrated on the one side. This increases the load on the finger.

  The present invention has been made in view of such problems. That is, the present invention provides a packaging box and a blank sheet, which are hand holes that can be formed quickly, do not limit the shape of the contents, and have excellent hand holes when used.

  The packaging box of the present invention is a packaging box having a pair of opposite side walls and a top plate extending from the upper end of the side wall through a score, and is formed inside the box to form a hand hole in the pair of side walls. A push piece that is pushed into the sidewall, the push piece being delineated by a first score line extending from a starting end on the score to an end located on the score and spaced from the starting end; It prepares for.

  When the pushing piece is pushed in to form a hand hole, the pushing piece comes into surface contact with the top plate, and the top plate and the piece are gripped simultaneously. Thereby, since the finger inserted into the hand hole comes into surface contact with the pushing piece or the like, it is possible to receive the load of the box in a distributed manner as compared with the line contact or the like. In addition, since there is no line contact, no load is applied to the finger and the finger can be gripped with the pressing piece in surface contact with the belly or palm of the finger, so there is no hand pain due to the load. Thus, the user can carry the box comfortably and stably.

  Moreover, since the hand hole is formed from the corner | angular part of a box, ie, a score part, a user will hold | grip a top plate part at the time of conveyance, and a hand hole will not be torn.

  In the packaging box of the present invention, the top plate is provided with an extension portion of the push piece, the contour of which is defined by a second cut line extending from the start end and the end end to the top plate beyond the score. There may be.

  In the packaging box of the present invention, when forming the hand hole, the score is a mountain fold line, and the push piece is not only pushed into the box, but also has the extension portion as described above. A form in which the end of the two cut lines extending from the start end of the top plate and the end of the line extending from the end is a mountain fold line, and the pushing piece and the extending portion are pushed into the box Can also be realized.

  Thus, if it is the form which pushes a pushing piece and an extension part into a box inner side, the front-end | tip of the finger inserted in the hand hole will also contact a pushing piece, and it can hold | grip more stably at the time of conveyance. In addition, since the extending portion is pushed inward, it is possible to create a state in which the upper inner flap is inserted in the vicinity of the hand hole. Therefore, it is possible to secure a space for inserting a finger when the upper outer flap overlapping the upper inner flap is peeled off. Therefore, the work at the time of unpacking becomes easy.

  Further, the packaging box is a rectangular parallelepiped, and is connected to the first width surface which is one of the side walls via a score on the first width surface, and the upper first inner flap which is the top plate, A lower first inner flap connected via a score under the first width surface, a first length surface connected to the first width surface via a crease, and a score on the first length surface Via an upper first outer flap that is the top plate, a lower first outer flap that is connected below the first length surface via a score, the first length surface and a crease The second width surface that is the other of the side walls, and the second width surface that is connected to the second width surface via a score, the upper second inner flap that is the top plate, and the score under the second width surface Via the lower second inner flap connected via the second width surface and the crease A second length surface, an upper second outer flap connected to the second length surface via a score, and a lower second surface connected to the lower length surface via the score. Two outer flaps and a joint connected to one of the first width surface and the second length surface via a crease may be provided.

  The blank sheet of the present invention is a packaging box having a pair of side walls opposed to each other and a top plate extending from the upper end of the side wall through a score, in order to form hand holes in the pair of side walls, A push piece that is pushed into the sidewall, the push piece being delineated by a first score line extending from a starting end on the score to an end located on the score and spaced from the starting end; To prepare for.

  The blank sheet of the present invention is provided with an extending portion of the pushing piece on the top plate, the contour of which is defined by a second cut line extending from the start end and the end end to the top plate beyond the score. There may be.

  An embodiment in which the packaging box of the present invention is applied to an assembly type wraparound case made of cardboard will be described with reference to FIGS. The present invention is not limited to such an embodiment, and can be applied to any other form of packaging box as long as it has a hand hole for conveyance.

  FIG. 1 is a perspective view showing the appearance of the packaging box of the present invention in a transparent state.

  FIG. 2 is a plan view of a blank sheet of the packaging box of FIG.

  A packaging box 10 in which a plurality of beverage bottles such as PET bottles are arranged and housed has a first width surface 11, a first length surface 12, a second width surface 13, a second length surface 14, and a joint. 15 and so on.

  In the assembled state, the first width surface 11 (side wall) and the second width surface 13 (side wall) face each other, and the upper first inner flap 16 (top plate) is located above the first width surface 11 via the score S1. The lower first inner flap 17 is connected to the lower side via the score S11. The first width surface 11 is connected to the first length surface 12 via a crease C1. Above the first length surface 12, an upper first outer flap 18 is connected via a score S2, and below the lower first outer flap 19 is connected via a score S12. The first length surface 12 is connected to the second width surface 13 via a crease C2. The upper second inner flap 20 is connected via the score S3 above the second width surface 13, and the lower second inner flap 21 is connected via the score S13 below. The second width surface 13 is connected to the second length surface 14 via a crease C3. An upper second outer flap 22 is connected via a score S4 above the second length surface 14, and a lower second outer flap 23 is connected via a score S14 below.

  Note that the lengths of the sides of the flaps 18, 19, 22, and 23 in the short direction, that is, the lengths of the sides in the direction perpendicular to the scores S2, S12, S4, and S14 are the scores S1, S11, and S3, respectively. , The width dimension of the first width surface 11 and the second width surface 13 along S13 is set to ½. Thereby, the packaging box 10 can be closed without gap and the sealing performance can be improved.

  The joint 15 for joining the first width surface 11 and the second length surface 14 is connected to the second length surface 14 via a crease C4.

  The overlapping portions of the outer flaps 18, 19, 22, and 23 and the inner flaps 16, 17, 20, and 21 are joined by an adhesive 24. Further, the overlapping portion 11 a of the first width surface 11 and the joint 15 is also joined by the adhesive 24. In the present embodiment, the joint margin 15 is overlapped on the inside of the first width surface 11 so that the joint margin 15 is not exposed to the outside, but the joint margin 15 is overlapped on the outside of the first width surface 11. It may be exposed to the outside.

  In the present embodiment, an adhesive is used for joining the flaps and joints. However, the present invention is not limited to this, and joining using various joining means such as a tape may be used.

  The first width surface 11 and the second width surface 13 opposed to the first width surface 11 at the time of assembly are respectively provided with hand holes 1 and 1 '.

  FIG. 3 is an enlarged plan view of a hand hole portion in the blank sheet.

  Hereinafter, the hand hole 1 formed in the first width surface 11 will be described, but the hand hole 1 ′ facing the first width surface 11 has the same form.

  The hand hole 1 is opened by pushing a substantially quadrilateral pushing piece 102a having a width corresponding to a plurality of fingers into the box. As shown in FIG. 3, the substantially quadrilateral pushing piece 102 a in the blank sheet is defined by a cutting line 101 that is continuous on three sides.

  The cut line 101 starts from one point 101a on the score S1 and extends downward on the first width surface (side wall) 11, and extends to a terminal end 101b provided on the score S1 so as to be separated from the score S1. Define the outline of

  The incision line 101 extends from the start end 101a and the end end 101b so as to be aligned in the horizontal direction on the flap 16 beyond the score S1, thereby defining the outline of the extension part 102b of the push piece.

  The terminal portions 101c and 101d of the part formed on the flap 16 of the cut line 101 are curved inward so as to face each other.

  In the present embodiment, the score line 101 extends to the top board beyond the score S1 and forms the extended portion 102b. However, the present invention is not limited to this, and does not have the extended portion 102b, and the score S1. It may be that which remains in the part (for example, the terminal part is located on the score S1). Further, the terminal portions 101c and 101d may be not only those that curve inward but also those that curve outward, or those that do not have a curve and extend straight. However, the score line 101 needs to extend to the vicinity of the score S1.

  Further, the cut line 101 does not need to be continuous from the one end portion 101c to the other end portion 101d, and may be interrupted in the middle. However, when the pushing pieces 102a are pushed into the box with a finger, it is preferable that the cutting lines 101 are formed at intervals such that the pieces 102a are easily separated from the first width surface 11.

  FIG. 4 is a view showing a first use example (formation example) of a hand hole.

  FIGS. 4A and 4B are cross-sectional views taken along the line II of FIG. 1 of the hand hole portion when the hand hole is formed in the first use example. FIG.4 (c) is a figure which shows an example in which the user grasped the hand hole.

  The user puts his / her finger on the pushing piece 102a positioned below the score S1 and pushes it into the box (see FIG. 4A). Then, the pushing piece 102a is bent into the box with the score S1 as a mountain fold line. The user folds the pushing piece 102a until the pushing piece 102a comes into contact with the flap 16 which is a top plate (see FIG. 4B). The push piece 102a, the flap 16 serving as the top plate, and the flaps 18 and 22 are sandwiched, and the box is held with the thumb and other fingers (see FIG. 4C).

  Since the pushing piece 102a of the hand hole is in contact with the top plate of the box, the belly of the finger inserted into the hand hole comes into contact with the pushing piece 102a and the top plate in a planar shape. When the box is lifted, three pieces of the pushing piece 102a and the flaps 16, 18, and 22 that are in contact with the surface overlap and come into contact with the belly of the finger. These three sheets act as a cushioning material when a box load is applied to the finger. In addition, since the pushing piece 102a comes into surface contact with the finger belly, the load applied to the finger belly is dispersed and the hand hurts when lifted, compared to the case where the contact point of the finger hole with the finger belly is linear. Hard to become.

  Further, since the top plate can be gripped by being sandwiched between the thumb and other fingers, the box can be lifted stably. In addition, since the finger is positioned in the direction along the top plate, the user is naturally encouraged to hold both hands, and the user carries the luggage in front of the body. Therefore, it is possible to prevent a load from being applied to only one side of the box and to prevent a drop due to breakage of the hand hole portion. Moreover, carrying by an unreasonable posture can be suppressed.

  Further, as described above, the user can configure a hand hole which is a stable gripping part by a single operation of pushing the pushing piece 102a into the box, and the hand hole part of the present invention is quick to carry. It is excellent in nature.

  Furthermore, it is sufficient if the pushing piece 102a is high enough to insert a finger. Accordingly, it is sufficient that the length (h1 in FIG. 3) of the portion extending downward from the shoulder portion of the score line box, that is, the portion where the score S1 is located, is about 3 cm. That is, the pushing space of the pushing piece 102a inside the box is not so much required, and the shape of the contents is not limited. Therefore, for example, a content such as a PET bottle having a high shoulder position can be stored in which the space for pushing the piece is reduced. In addition, since the push-in piece 102a is small, the printable area on the outer surface of the box is increased, and the restriction on the printed image is reduced.

  FIG. 5 is a diagram showing a second usage example (formation example) of the hand hole.

  FIGS. 5A and 5B are cross-sectional views taken along the line II of FIG. 1 of the hand hole portion when the hand hole is formed in the second usage example.

  As shown in FIG. 3, the cut line 101 of the hand hole 1 exceeds the score S <b> 1, and end portions 101 c and 101 d are formed on the flap 16. With the score S1 as a boundary, the length of h1 of the pushing piece 102a positioned below is about 3 cm, and the length of h2 of the upper extension portion 102b is about 1.3 cm.

  In this usage example, the point where the cut line 101 is formed up to the top of the flap 16 beyond the score S1 is used by folding the pushing piece 102a further inside than the score S1.

  Specifically, in the first usage example, the pushing piece 102a is folded using the score S1 as a mountain fold line. In the second use example, the pushing piece 102a and the extending portion 102b are pushed into the box using the line 103 (see FIG. 3) connecting the end portions 101c and 101d of the inner cut line as a mountain fold line (see FIG. 3). (See FIG. 5 (a)). The surface in contact with the top plate of the box is both the pushing piece 102a and the extending part 102b extending over the length H in FIG. 3, and the end of the pushing piece 102a is located inside the box from the first use example. Become.

  Therefore, when the finger is inserted into the hand hole 1, the pushing piece 102a also comes into surface contact with the tip portion of the finger, so that the finger contact condition when the user holds the box is improved.

  The end portions 101c and 101d of the cut line are curved inward, but as described above, the present invention is not limited to this. However, if the end portions 101c and 101d of the cut line remain straight, the paper is easily torn along the cut line 101. It is desirable that the end portions 101c and 101d have a curved portion on either the inner side or the outer side because the paper is difficult to tear from the end portions 101c and 101d.

  As shown in FIG. 6, in the second usage example, the folding of the piece enters the corner part between the side wall of the box and the top plate, that is, the side by the score S <b> 1 by h <b> 2. Therefore, the top plate in the portion from the corner to the broken line 103 is only the upper first outer flap 18 and the upper second outer flap 22. Therefore, when opening the packaging box, a finger can be put into the space with the hand hole formed by the extension portion 102b moving backward, and the end of the flap 18 or 22 can be gripped and pulled up.

  Thus, since only one outer flap forms a space that does not overlap with the inner flap, the end of the flap 18 or 22 is gripped as compared with the case where only the pushing piece 102a is folded at the position of the score S1. It becomes easy and can be opened easily.

  The upper first outer flap 18 and the upper second outer flap 22 and the upper first inner flap 16 are joined with an adhesive, but the end portions of the upper first outer flap 18 and the upper second outer flap 22 are used. To the piece 102 broken line 103, no adhesive is applied.

  Further, the shape and size of the hand hole 1 should be arbitrarily modified and selected according to how to hold it, and are not limited to the present embodiment. In addition, the line 103 connecting both end portions 101c and 101d of the cut line of the hand hole 1 may be folded in the same manner as the score so as to be easily broken in advance, or may not be processed at all. The same plate shape may be used.

  Further, the present invention is characterized in that the hand hole is located at the corner between the top plate and the side wall of the box, and the shape of the packaging box is not limited to a rectangular parallelepiped, but in various shapes such as a hexagonal column. Even if it exists, the same effect can be produced.

  Furthermore, the present invention should be construed only from the matters described in the claims, and in the above-described embodiments, all the changes and modifications included in the concept of the present invention are other than those described. Is possible.
