Description

  The present invention relates to a container formed of a corrugated cardboard sheet. Specifically, in a container made of a corrugated cardboard sheet, the edge of the corrugated cardboard sheet exposed to the outside has a continuous corrugated shape. The present invention relates to a corrugated cardboard container provided with a cut at each bottom. For example, when carrying a cardboard box, the present invention prevents a person's hand, finger, etc. coming into contact with the edge of the cardboard sheet exposed to the outside from being cut, and has a non-slip function on the cardboard box. This is a cardboard box with added safety, which improves the work efficiency of handling the cardboard container and provides a cardboard container that is easy on the human body.

  It is well known that careless handling of thin paper can result in a sharp edge at the periphery and cuts the hand and fingers. Similar effects often occur in synthetic resin or cardboard packaging containers used to store or transport articles. For example, when opening a packaging box containing a plurality of articles and taking out the stored articles, the flap edge is sealed with an adhesive with adhesive as the glue during packaging. It is necessary to open it by prying open. At this time, if the hand or finger touches the edge of the cardboard flap portion and slides, the hand or finger may be cut like the peripheral portion of the thin paper. This is considered to be caused by the fact that the edge of the thin paper portion called the front liner and the back liner adhered to the front and back surfaces of the cardboard functions in the same manner as the thin paper, and is not limited to materials and materials, but also composite paper, cardboard paper, It may also occur in resin films. Conventionally, many proposals have been made to solve the problem of cuts such as fingers in such packaging containers.

For example, in a conventional synthetic resin case where all the outer peripheral parts of the wall surface part, the insertion part, the bending part, and the adhesive part are cut straight, it can be used as a protruding edge part such as an insertion part or a bending part during assembly work or carrying. When the operator touches the hand, there is a risk that the finger is cut by the acute angle portion of the protruding edge portion, but in the container made of a synthetic resin sheet, it becomes the entire outer peripheral portion and a bent portion for case formation. Injuries such as fingers are prevented by assembling the entire ruled line portion into a wave shape (Patent Document 1).
In addition, by forming at least a part of the edge of the box-forming plate-shaped member formed by folding the packaging container into a continuous corrugated shape having a period of 4 to 8 mm and a depth of 1.5 to 3 mm, When the packaging member is formed by folding the plate-like member, the plate-like member can prevent the hand or finger from being damaged at the edge of the plate-like member even when the container is closed or opened. Has been proposed (Patent Document 2).

  As a corrugated cardboard carton that wraps and stores beverage containers in multipacks, the inner flap extends from the edges of the pair of side plates, the outer flap extends from the edges of the other pair of side plates, and the inner and outer flaps are bonded together. A type that closes the end face is used. When taking out a multipack from such a carton, put a finger into the abutting part of the outer flap, peel off the outer flap from the inner flap, open the end surface of the carton, and take out the multipack from the opening. Well done. At this time, there is a problem that it is easy to cut the hand at the edge of the outer flap, so in the conventional carton, a waveform with a pitch of about 2 mm is formed on the outer periphery so that the hand does not come into linear contact with the edge of the outer flap. However, sufficient effect is not obtained. Therefore, further improved proposals have been made.

  For example, in the corrugated cardboard carton in which the inner flap extends from the edge of the pair of side plates and the outer flap extends from the edge of the other pair of side plates, and the end surface is closed by bonding the inner flap and the outer flap. A cardboard carton has been proposed in which the edges are weakened by crushing or ruled lines to soften the hand, and the edges of the outer flaps are uneven to prevent hand slipping to prevent hand slipping. . Specifically, the outer flap is provided with a ruled line parallel to the leading edge, the outer flap is provided with a perforation close to the edge, and the outer flap is formed with a minute waveform with a pitch of about 1 mm. Finger edges are prevented by arranging arc-shaped cuts at intervals between the edges of the outer flap, with the edges of the edges being wavy edges with a period of about 20 mm to 40 mm.

  Further, in a corrugated cardboard carton in which an inner flap is connected to a pair of side plates and an outer flap is connected to another pair of side plates, and the inner flap and the outer flap are bonded together to close the end face, a plurality of edges are provided at the edge of the outer flap. A wavy crushing portion is formed by putting a ruled line of the strip. The core of the corrugated sheet is crushed intensively at the part of the ruled line, and the liner is strongly stretched, preventing the crushed part from being restored, and when opening the carton, when the hand is put on the edge of the outer flap, There has been proposed a corrugated cardboard box in which the effect of softening the hit and preventing the hand from being cut easily is maintained (Patent Document 4).

  On the other hand, as a boxing device in a cardboard box, conventionally, a device that collectively stores products in a pre-assembled cardboard box has been used (for example, Patent Document 5). Recently, other types of boxing devices have been used. Among them, a packaging apparatus that wraps an article such as a can containing beer with a box material while forming a plate-like box material (carton material) into a box shape is known. This apparatus wraps an article with a box material in the process of forming a plate-like box material into a box shape, and then sprays glue on the inner flap of the box material, and then folds the outer flap and presses it against the inner flap. As a result, the outer flap is glued to the inner flap and the box is assembled, and at the same time, the article is stored (Patent Document 6, Patent Document 7). Even in a corrugated cardboard container packaged by an apparatus that simultaneously assembles and packs such a packaging container, fingers and other cuts often occur during transportation by hand, and it remains as a problem to be solved.

In such a situation, in view of the above-described prior art, the present inventors have suppressed that the edge portion of the corrugated cardboard sheet exposed to the outside of the corrugated cardboard container becomes a sharp state, and the human body by the edge portion. As a result of intensive research with the goal of reducing cuts to the edges, at least one side of the edge of the corrugated cardboard sheet exposed to the outside has a continuous corrugated shape, and further, the bottom of each corrugated shape has a notch. The present invention has been found out that it is possible to provide a safe corrugated cardboard container by using the composite shape provided.
An object of the present invention is to provide a corrugated cardboard container which prevents finger cuts and rough skin due to the edge of the corrugated cardboard sheet exposed to the outside of the corrugated cardboard packaging container and is easy to handle.

Even if the user holds the finger, the finger is prevented from slipping by being caught by the corrugated concave portion or convex portion, so that the finger can be prevented from being wounded, rubbing, and rough skin. In addition, a safe corrugated cardboard container can be provided. Since the corrugated composite portion becomes a clue for gripping the cardboard box, it is easy to hold the cardboard container, and the risk of dropping during carrying is greatly reduced, so that the work efficiency is increased.

An example of a corrugated cardboard container in which the composite shape of the present invention is provided in the stop margin is shown. The other example of the cardboard container which provided the composite shape is shown. The enlarged view of the waveform shape and the composite shape which provided the notch in the bottom part of the wave is shown. The expanded view of the cardboard container of FIG. 1 is shown. The expanded view of the cardboard container of FIG. 2 is shown. The example which provided the composite shape of this invention in the Bliss box is shown. The composite shape formed in the stop margin part in Example 1 is shown. The contact state of the composite shape and polyurethane in the test in an Example is shown.

  The present invention is characterized in that, in a cardboard container formed of a corrugated cardboard sheet, flexibility is imparted to an edge portion of the corrugated cardboard sheet exposed to the outside, and specifically, exposed to the outside. The present invention relates to a corrugated container in which one side of the corrugated cardboard sheet has a continuous corrugated shape, and a cut is provided in each bottom portion of the corrugated shape. By adopting a composite shape consisting of a corrugated shape and incisions provided at the bottoms of the corrugated cardboard, it is possible to carry a corrugated cardboard container without injuring the finger or the like and making it easy to carry. The present invention combines the corrugated shape and the incision to give flexibility to the edge of the corrugated cardboard sheet, thereby preventing excellent fingers and other cuts that could not be achieved with the prior art and transporting them safely by hand. It became possible to achieve.

Next, the present invention will be specifically described.
The corrugated cardboard container of the present invention is characterized by a composite shape having a flexible structure in which at least one side of the edge of the corrugated cardboard sheet exposed to the outside has a continuous corrugated shape and a notch is provided at each bottom of the corrugated shape. The shape and structure of the cardboard container are not particularly limited. There are several types of corrugated containers, for example from a grooving form, with a flap in one piece and with a stop margin attached to either the length or width side, as well as the body and lid A telescope type consisting of two or more pieces, an assembly type that can be assembled in one piece without a stop margin, basically a plug type consisting of an outer frame and an inner frame that plugs into it, a Bliss type that consists of a three piece and is assembled and assembled, one piece Many types are known, such as a simple assembly type that can be easily assembled by folding and joining. The present invention can be applied to all types of containers having cardboard sheet edge portions exposed to the outside. There is no particular limitation on the type of corrugated cardboard sheet used as a material for the corrugated cardboard container used in the present invention, and the corrugated cardboard sheet conventionally used according to the size of the container, the shape structure of the article to be stored, the weight, etc. You may choose from.

  A typical example of the cardboard container of the present invention is shown in FIGS. FIGS. 1 and 2 are of a type in which a corrugated cardboard sheet composed of four side plates 1, 1 ′, 2 and 2 ′ is bent and its edge is bonded by a stop margin 4 to form a body of the container. 1 shows a corrugated cardboard container in which the stopper margin 4 is bonded to the outer surface of the side plate 2 to form a cylindrical body. FIG. 2 shows a corrugated cardboard container in which the side plate 1 is bonded on the stopper margin 4. In the corrugated cardboard box shown in FIG. 1, the composite shape of the present invention is formed in the stopper margin 4, and in the corrugated cardboard box shown in FIG. 2, the composite structure of the present invention is formed on the side plate 1.

A composite shape composed of a corrugated shape formed at the edge of the corrugated cardboard sheet exposed to the outside of the present invention and a notch formed at each bottom of the corrugated cardboard shape is cut from the corrugated cardboard sheet according to the development of the corrugated cardboard container. It is preferable to form them at the same time, and the shape and structure thereof will be described below with reference to the enlarged view of FIG. 3 while showing preferred ranges obtained from many test results.
The period (W) of the waveform shape in the present invention is selected from the range of 10 to 16 mm. If the period (W) of the corrugated shape is less than 10 mm, it becomes difficult to form a composite shape of the edge of the corrugated cardboard sheet, and the contact area between the edge and the body and fingers increases, resulting in damage to the human body. Since it cannot reduce, it is not preferable. In addition, if the period (W) of the waveform shape exceeds 16 mm, the contact state between the finger and the edge portion is not different from that in the case of a linear shape, and it is not preferable because damage prevention of the finger or the like is not sufficient.

The distance (H) from the top 10 to the bottom 11 of the corrugated shape is selected from the range of 4 to 12 mm. If the distance (H) from the top 10 to the bottom 11 of the corrugated shape is less than 4 mm, the contact between the finger and the edge increases, and finger damage cannot be reduced. When the distance (H) from the top portion 10 to the bottom portion 11 of the corrugated shape exceeds 10 mm, that is, when the valley becomes deep, there is a large portion in the back where the valley and the finger do not contact, and the meaning of providing the corrugated shape is lost.
The waves forming the waveform shape may be single or a combination of various waves. For example, a combination of waves having different periods and amplitudes, a single wave such as a sine wave, a rectangular wave, and a triangular wave, or a combination of waves having different waveforms can be selected as appropriate.

The cut 12 is preferably provided in the corrugated bottom 11, but may be provided in any part of the concave curved surface. The length of the cut is preferably in the range of 5 to 7 mm. When the length of the cut 12 is less than 5 mm, the buffering effect due to the cut is lost, and when the length exceeds 7 mm, the cut is provided even in a portion that does not contact the finger, and the length becomes longer than necessary. Moreover, it leads to the strength fall of a stop margin. The incisions 12 are oriented in the interior direction of the corrugated sheet and may be provided, for example, from the lowest (bottom) position of the wave to the edge or approximately perpendicular to the edge of the container. This notch 12 may cut the thickness of the corrugated cardboard sheet completely, or may be in a state of being cut to a certain depth from the outer surface, and is a straight line, a curve, or a V-shape having a cut at the end face of the cardboard sheet. It may be a cutting line or a cutting plane.
The portion of the complex shape having a corrugated shape and a notch at the bottom thereof may be provided at a free end portion that may come into contact with, for example, a finger at the edge of the inner flap or the outer flap, or a stop margin Thus, a member whose one surface is bonded to another member may be used, and in any case, the effect of preventing hand breakage of the present invention can be exhibited.
For example, in a stop margin having a composite shape including notches, one surface of the end edge is bonded and fixed to the corrugated cardboard sheet surface, but the other surface, that is, the surface portion is released to provide a certain degree of freedom. Have. Therefore, when a force is applied to the finger or the like at the cut portion, the surface layer of the edge portion including the periphery of the cut is deformed, and the force applied to the finger can be reduced. Moreover, the sharp part of an edge part can be reduced.

  The shape of the waveform is not particularly limited, but may be a triangular wave, a square wave, or the like. Preferably, for example, a sinusoidal waveform that is a gentle wave, or a repetition of a waveform shape in which a semicircular arc-shaped convex portion and a semicircular arc-shaped concave portion are combined. FIG. 3 shows an enlarged example of the composite shape of the present invention employing a sine waveform. The optimum value of the waveform shape is a wave whose period (W) is 13 mm, the distance from the top to the bottom (H) is 10 mm, that is, the amplitude is 5 mm, and the optimum value of the cut (D) is 6 mm. doing. Further, by crushing the corrugated shape and / or the cut portion, flexibility can be further imparted to the edge portion, and the effect of preventing the formation of cuts can be enhanced.

The invention is further illustrated by specific examples.
2. Description of the Related Art Conventionally, a packaging device that stores articles such as shochu, beer-containing bottles, cans, and paper containers in a box while forming a plate-like cardboard sheet into a box shape is known. In this apparatus, an article is arranged on the corrugated cardboard sheet in the middle of forming the corrugated cardboard sheet cut along the developed view of the container into a box shape, the corrugated cardboard sheet is folded and wrapped around the article with a trunk, and then the outer flap is A container enclosing the article is obtained by being glued to the inner flap and closing the opening of the barrel.

  Articles to be packaged by such an apparatus are cans such as packed liquor, beer cans or beverage cans or bottle products. For example, an assembly of 4 × 6 bottles is packaged in a container. In a so-called multipack product, typically, an assembly of four multipacks each packaged in units of 2 × 3 is packaged in a container.

In order to wrap an article by this apparatus, one piece is taken out from a plurality of stacked cardboard box sheet materials and used for packaging. For example, the cardboard box sheet material is placed on a conveyor by bending two sides of the body part. Thereafter, the container material is processed while being transported in the transport direction by the transport mechanism. Next, the inner flap on the guide member side is folded about 90 degrees, the article is transferred and filled on the inner surface of the container material by the filling mechanism, and then the inner flap on the opposite side is folded about 90 degrees. Finally, the sheet material is bent at a height for storing the article, covers the upper part of the article, and adheres to the stop margin provided at the end, thereby completing the packaging.
When the stopper margin and the side plate (container material) are bonded to each other, the container is completed with the stopper margin outside the corrugated cardboard sheet of the trunk portion, and the composite shape of the present invention is provided at the edge of the stopper margin. The appearance of the container is as shown in FIG. On the other hand, in the method of completing the container with the corrugated cardboard sheet outside, the outer appearance of the container is as shown in FIG. 2 when the composite structure of the present invention is provided at the edge of the corrugated cardboard sheet forming the trunk.

  The packaging container is formed by bending and bonding a plate-like material obtained by cutting a corrugated cardboard sheet based on the development view. When a specific example of the development view is illustrated, the development of the corrugated container having the appearance of FIG. The figure is shown in FIG. A sheet material is cut out from a large corrugated cardboard sheet along a development view, bent along a fold line, and bonded to form a container. In the corrugated cardboard box assembled from FIG. 4, the side plates 1, 1 ′, 2, 2 ′ are continuous, and a stopper margin 4 is provided at one end thereof. 5 is formed. Inner flaps 7 and 7 or outer flaps 6 and 6 are respectively provided on the outer sides of the side plates in the width direction. When the container is formed by bending the sheet material, the stopper margin 4 is joined to the surface of the side plate 2 from the open end 8 of the side plate 2 with an adhesive or the like to form the body of the container. The composite shape 5 provided in the stopper margin 4 is exposed on the surface of the container, and is used as a clue when transported manually. However, the provision of this composite shape 5 damages the fingers and the like. There is nothing.

  FIG. 5 shows a development view of the cardboard container having the appearance of FIG. FIG. 3 is a developed view similar to FIG. 2, but differs in that the end edge portion of the stop margin portion 4 has a linear shape and the end edge portion of the side plate 2 is provided with a composite shape 5. The side plate 2 and the stop margin 4 are bonded to form a body portion, and the opening portions of the body portion are closed by the inner flaps 7 and 7 and the outer flaps 6 and 6.

  The present invention can be applied to Bliss type boxes as other types of cardboard containers. The appearance is shown in FIG. The Bliss type box has a main panel that forms a square cylindrical body by bending one cardboard in the same direction. Stopping margins 23 and 23 are projected from both sides in the width direction from three continuous side plates 20 constituting the main panel, and flaps 22 and 22 are provided on the side plates at both ends to form an outlet for storing articles. To do. A corrugated cardboard side panel 21 is adhered to the inside of the stop margin with an adhesive to assemble a rectangular parallelepiped-shaped Bliss box as a whole. In this type of container, the blister box has high compressive strength from above because the vicinity of the vertical ridge of the blister box is reinforced by the stopper margin. The Bliss Box is strong and excellent in durability, and is particularly suitable for storing and transporting heavy objects.

In the Bliss type box, since the stop margin 23 is located outside the Bliss box, the cardboard edge of the stop margin 23 appears outside. Bliss boxes with many cardboard end portions exposed to the outside like this are easy to be held by carrying fingers on these ends when carrying, because force is applied between the cardboard edge and the fingers, There is a high possibility that the finger slides on the edge and damages the finger. In particular, when a heavy object is placed in the Bliss box, the overall weight increases and the possibility of damage increases.
In such a brick box type container, the edge portion of the stopper margin 23 is mainly formed into the composite shape 24 of the present invention, which is composed of a corrugated shape and a notch, so that it is possible to prevent hand cuts during transportation.
Next, the cardboard box of the present invention confirms the effect of preventing damage to fingers and the like by comparing the specific example of the cardboard box of the present invention with the specific example of the current cardboard box that does not have the composite structure of the present invention. did.

In order to demonstrate that the cardboard box of the present invention can prevent hand cutting due to the stop margin, a test was performed in comparison with the stop margin in the current cardboard box.
The corrugated cardboard sheet forming the corrugated cardboard box was manufactured by Tomok Co., Ltd., and the standard was white BWF220 / reinforced 200 / K220 AF.
The stop margin part was formed in the shape shown in FIG. The interval (W) between the ridges of the corrugated crest formed at the edge of the stop margin was 13 mm, the crest to the trough (the depth H of the trough) was 5 mm, and the crest and trough were processed to R2.5. A cutting line was provided as a cut (D) having a depth of 6 mm in the valley bottom (see FIG. 7). Fix the stop margin created in this way, and make a commercially available polyurethane sponge (manufactured by Hanwa Kogyo Co., Ltd.) a rectangular parallelepiped at the tip, and slide it 10 times while holding the end by hand and making light contact with the stop margin. The condition of the surface of the sponge was observed. FIG. 8 shows a state where the stopper margin and the polyurethane sponge are in contact with each other.
The same test was performed on the current corrugated cardboard sheet (made by Tomok Co., Ltd., white BWF220 / reinforced 200 / K220 AF) having a straight stop margin (cut with a wave blade 3P) at the end, and the test results of the present invention In contrast, the polyurethane of the present invention was less damaged than the current product.

  The waveform formed on the edge of the stop margin is except that the interval (W) of the peak is 15 mm, the depth (H) of the valley is 11 mm, the cut length (D) is 6 mm, and the stop margin is crushed. The test was performed in the same manner as in Example 1. From this test, it was found that the stop margin of Example 2 was less damaged by polyurethane than the current corrugated cardboard sheet, and that the polyurethane was less damaged than the stop margin performed in Example 1.

  The waveform formed on the edge of the stop margin is except that the crest interval (W) is 13 mm, the trough depth (H) is 5 mm, the cut length (D) is 6 mm, and the stop margin is crushed. The test was performed in the same manner as in Example 1. According to this test, the stop margin of Example 3 is less damaged by friction of polyurethane than the current stop allowance, and is less damaged by polyurethane than Example 1 and comparable to Example 2. I understood.

[Comparative Example 1]
The interval between peaks (W) is 10 mm and the depth of valley (H) is an approximately triangular waveform. The shape of the peaks and valleys is not sharpened without R machining, and no cuts are made. The stop margin part which has an edge part was formed with the 1.3P wave blade, and the damage state by friction of polyurethane was observed like Example 1. FIG. The damage due to this stop margin was greater than the current stop margin.

[Comparative Example 2]
A straight notch having a length of 12 mm was formed at intervals of 8 mm at the edge of the stop margin formed by linearly cutting with a 1.3 P wave blade. When this stop margin was tested in the same manner as in Example 1, the damage was greater than the current stop margin, but less than Comparative Example 1.

  From the above test results, the damage state of polyurethane can be summarized as follows: Comparative Example 1> Comparative Example 2> Current Cardboard Box> Example 2> Example 4 = Example 3 It has been demonstrated that the present invention can achieve the prevention of hand breakage by a corrugated cardboard box in which the edge portion of the corrugated cardboard sheet has a continuous corrugated shape and the bottom of each corrugated shape is provided with a cut.

  Conventionally, boxing of articles has been automated, and almost nothing has been done manually. However, it is inevitable that manual operations will be relied upon in the stage of container movement and transportation after boxing. In such a field where handling such as movement and transportation for each container is required, fingers or the like often come into contact with the corners of the container or the exposed edge of the corrugated cardboard sheet and are cut. The present invention provides a corrugated cardboard container that is useful for eliminating the generation of scratches on the human body when the corrugated cardboard container is transported and handled. By eliminating the adverse effects on the human body by using the cardboard box of the present invention, it is not necessary to use a tool for protecting the human body, and the working efficiency is remarkably improved. In addition, the overall efficiency of the packaging and transportation industry is improved, and an excellent effect is provided that makes it possible to provide human-friendly working conditions.
