Description

The present invention relates to a packaging member made of cardboard for packaging a mobile phone and its accessories. Specifically, it is a packaging member for wrapping a multifunctional thin mobile phone and its accessories that combine the functions of a mobile information terminal such as a smartphone, and can be stored in multiple locations by folding it up from a piece of corrugated paper. The present invention relates to a packaging member in which a product body and its accessory parts can be stored compactly.

Electronic devices such as digital cameras, digital video cameras, mobile phones, especially smartphones with built-in glass parts such as electronic components and liquid crystal displays are particularly vulnerable to falling and external shocks and are easily damaged. . For this reason, these product bodies are wrapped with a cushioning material, and accessories, instruction manuals, and the like are stored around it. Multifunctional thin mobile phone bodies such as smartphones are often packaged together with accessories such as battery packs and charging adapters, so it is necessary to efficiently accommodate different shapes in a single box space. . For example, in an example of packaging a conventional mobile phone, a resin molded product inner box having a shape matched to the mobile phone body and a battery is mounted on a cardboard outer box. As another method, an irregular cushion material such as sponge is packed in the gap between the outer box made of cardboard, the main body and the battery. In addition, a conventional example of a cardboard packaging member for packaging a multifunctional type such as a smartphone, in particular, a thin mobile phone is shown below. As shown in FIG. 21, the accessory tray 200B ′ is placed on the lower stage of the outer box 200C ′, and the buffer tray 200A ′ is placed thereon. Details of the lower accessory lay 200B ′ are shown in FIG. 20, and various shaped accessories are stored in the recesses surrounded by the four side walls. For example, accessories such as a USB cable for PC connection, a charging cable, an earphone conversion adapter, and the like are separated and stored in a portion partitioned by the flap 7B ′ in the recess 300B ′. The details of the upper buffer tray 200A ′ are shown in FIG. 19, and the smartphone main body, the battery pack, and the battery cover are stored in the recess 300A ′ surrounded by the four side walls. In addition, it shows in FIG. 18 as buffer tray cardboard 100A 'which is an expanded view of buffer tray 200A'. According to the accessory lay 200B ′ and the buffer tray 200A ′, for example, the buffer tray cardboard 100A ′ shown in FIG. 18 is formed in a different shape with four corners dropped from a rectangular cardboard paper material. Usage yield is low. In addition, since the buffer tray cardboard 100A ′ is designed so that the side wall and various shapes of flaps and folds are entangled in a complicated manner, the assembling procedure is complicated and difficult to bend. In addition, since the buffer tray is placed on the upper edge of the side wall of the lower accessory tray, the overall height of the stacked layers increases.

In addition, the applicant has previously proposed a packaging box for a cellular phone that is not thin. Specifically, the configuration is as follows. By folding up a piece of corrugated paper, dents for storing the product body of electronic devices such as mobile phones and accessories such as batteries are formed, and the product body and accessories are safely placed in these dents, and The purpose is to store it securely. In addition, in some cases, the cardboard paper is delivered in a flat folded state, and the product body or accessories are stored by instantly folding the corrugated board from the folded body into a rectangular parallelepiped box in the product packaging line. It is the purpose. The configuration is such that a substantially rectangular cardboard is divided into a top surface, a bottom surface, left and right side walls, an inner side wall, and the like through a plurality of folds or cuts, and the cardboard is folded up to form a substantially rectangular parallelepiped box This rectangular parallelepiped box is composed of the upper surface, the bottom surface, the left and right side walls, the inner side wall that folds on one side wall from the inside, and the like. And the main body is formed with a recess so that a part of the bottom surface is surrounded by the left and right side walls, the inner side wall, and the front and rear main body side pieces. A packaging member in which a recess is formed by folding a part of the upper surface to the bottom surface side through a crease, and various stopper pieces are provided on the upper surface or the inner wall via the crease, respectively. These stopper pieces are bent from the crease to the inside of the box, and these stopper pieces are positioned on the back side of the main body side pieces before and after the main body portion, respectively (Patent Document 1). ).

JP 2010-137877 A

As described above, conventional packaging members for packaging electronic devices such as smartphones such as smartphones and their accessories have the following problems.

In addition to a multifunctional thin mobile phone body such as a smartphone, the height of stacking a buffer tray on an accessory tray serving as a packaging member for storing accessories of various shapes increases. In addition, the yield of corrugated paper material is low. In addition, there is a problem that the number of steps for assembling the buffer tray is increased and the cost is increased.

The present invention has been made to solve the above-described problems, and its purpose is to fold up from a piece of corrugated cardboard, and to attach a multifunctional thin mobile phone body such as a smartphone and various shaped accessories such as a battery pack. By forming recesses for storing the products and providing these recesses with a buffer function, the product main body and accessories can be stored without being damaged, and can be stored compactly and efficiently. It is in providing the packaging member made. Moreover, it is an object of the present invention to provide a packaging member that can reduce the time for folding from a piece of corrugated paper and can reduce the cost by reducing the amount of corrugated paper used.

In order to achieve the above object, the invention of claim 1 is a packaging member formed by bending cardboard and incorporated in an outer box, and is composed of an accessory tray and a buffer tray, and the accessory tray has four sides. The side walls of the tray rise from the bottom surface to form a recess, and the buffer tray has four side walls from the bottom surface to form a recess, and a convex portion is formed on the back side of the bottom surface. The convex portion on the back side of the buffer tray is fitted into the concave portion. According to a second aspect of the invention, in addition to the above feature of the first aspect of the invention, a pair of front and rear flaps are substantially upright from the bottom surface at the center of the concave portion of the accessory tray, and a pair of left and right reverses is placed on the upper sides of these flaps L-shaped sides are formed, and convex portions on the back side of the buffer tray are fitted to the pair of L-shaped sides. According to a third aspect of the invention, in addition to the above feature of the first aspect of the invention, the buffer tray has a configuration in which a middle buffer tray member is engaged with a lower buffer tray member, and the left and right of the lower buffer tray member are An obtuse corner is provided on the side wall, while a wedge-shaped projection is provided on the front and rear side walls of the middle buffer tray member, and the projection is locked to the corner. According to a fourth aspect of the invention, in addition to the above feature of the first aspect of the invention, an upper buffer tray member is placed in the concave portion of the buffer tray, and a mobile phone body is housed on the upper buffer tray member. According to a fifth aspect of the present invention, in addition to the above feature of the first aspect of the invention, an accessory is accommodated in the concave portion of the accessory tray.

Here, the “buffer tray” in the present specification refers to a bowl-shaped packaging member for loading a multifunctional thin mobile phone body such as a smartphone equipped with a liquid crystal display so as not to be damaged. The “accessory tray” refers to a bowl-shaped packaging member for efficiently storing accessory parts of various shapes.

According to the packaging member made of corrugated cardboard according to the present invention, the mobile phone main body is protected from damage due to an external impact in storing a multifunctional thin mobile phone main body such as a smartphone and accessories such as a battery pack, and It is a packaging member that can store accessories efficiently and compactly and has excellent practicality. Since the buffer tray and the accessory tray are formed with the recesses for individually storing the thin mobile phone main body and accessories, the thin mobile phone main body and accessories are mutually buffered to cause scratches. In addition, the product can be protected from damage caused by external impact. In these recesses, a three-dimensional space is formed by the four side walls and the plurality of flaps, and therefore, has an excellent buffering function. When viewed from the producer side of the packaging member of the present invention, the production efficiency was improved as follows. As for the assembly of the buffer tray, a dent is formed along the crease by placing a cardboard with a fold in advance on an assembly jig having a dent and pressing the cardboard from above following the dent. . The buffer tray of the present invention has good workability such as the fact that the folds are efficiently arranged on the cardboard and the assembly jig is used, so that the buffer tray can be folded up in half the time compared to the conventional case. Next, when stacking the folded buffer trays, the convex part on the bottom side of the upper stage fits and sinks into the concave part of the lower stage, so the stacking height is lowered, and the buffer trays are stacked in multiple stages. Can do. For this reason, when delivering the buffer tray, the stacking efficiency is good because the stacking tray number can be increased by 60% compared with the conventional one. Similarly, in the case of the other accessory tray, the convex part on the bottom side of the upper stage is fitted into the concave part of the lower stage and the stacking height is lowered while sinking, so that the accessory trays can be stacked in multiple stages. When delivering, the stacking efficiency is good because the number of stacks can be doubled. Assuming that 200,000 units of these packaging members are delivered per month, for these reasons, it is possible to reduce the amount of two 4-ton trucks compared to the conventional case. In addition, the amount of corrugated cardboard used for the buffer tray could be reduced by 40% compared to the prior art. Along with this reduction in cardboard usage and assembly time, a significant cost reduction has been achieved. On the other hand, from the producer side of multifunctional thin mobile phones such as smartphones, when storing accessories such as mobile phone bodies and battery packs in packaging members, they are thin on the accessory tray that stores the accessories. The height of the stacking of the buffer tray containing the mobile phone main body and other accessories is reduced, and the packaging member can be downsized. Specifically, the height at which the buffer tray is stacked on the accessory tray is 11 mm lower than the conventional one.

Next, the middle buffer tray cardboard 100A2 is placed on the lower buffer tray member 200A3 placed on the assembly jig 50 of FIG. 6, and this state is shown in FIG. Since the dimension of the outer contour 52 of the assembly jig 50 is also matched with the outer dimension of the middle buffer tray cardboard 100 A 2, the cardboard fits in the recess 521 on the inner periphery of the outer contour 52. Next, the front and rear side walls 5A and 6A are pushed and bent downward from the fold lines K, L, M, and N, respectively. In this way, the side wall is bent obliquely downward following the shape of the recess 531 at the center of the assembly jig 50, the lower buffer tray member 200A2 is overlapped on the lower buffer tray member 200A3, and the side walls are entangled and fitted. Is done. FIG. 4B shows a perspective view of only the middle buffer tray member 200A2 in which the front and rear side walls are bent obliquely downward and the bottom surface 7A is formed at the center. Next, on the assembly jig 50, the middle buffer tray member 200 </ b> A <b> 2 overlaps from above the lower buffer tray member 200 </ b> A <b> 3, and the side walls are entangled and fitted along the front and rear ends of the middle buffer tray member 200 </ b> A <b> 2. The stop piece 8A is engaged with the cutout hole 4A of the lower buffer tray member 200A3 from the portion of the crease J and united so that the overlapped state is not separated. This state is shown in FIG. 8 as a perspective view of the buffer tray 200A. In FIG. 6A, the middle buffer tray member 200A2 is overlapped from above the lower buffer tray member 200A3, and the four side walls that are bent obliquely downward are entangled and fitted. That is, the left and right side walls 2A and 3A of the lower middle buffer tray member 200A3 can be seen between the front and rear side walls 5A and 6A of the upper middle buffer tray member 200A2, and the four side walls are entangled. In this way, the bowl-shaped buffer tray 200A having a recessed central portion is completed, and the side walls of the four sides rise obliquely upward and expand toward the opening, thereby forming a recessed portion 300A in which the central bottom surface 7A is recessed. . At the center of the buffer tray 200A, the convex portion of the middle buffer tray member 200A2 is fitted into the concave portion of the lower buffer tray member 200A3, and at the upper and lower ends, the locking piece 8A of the middle buffer tray member 200A2 is from above to the lower buffer tray. The member 200A3 is engaged with the cutout hole 4A. A symbol W1 in a ridge line portion formed by intersecting the front and rear side walls 5A and the left and right side walls 2A is a locking portion that couples the middle buffer tray member 200A2 and the lower buffer tray member 200A3. FIG. 2B shows a state in which the buffer tray 200A is turned over and viewed from the back side. The middle buffer tray member 200A2 is covered with the lower buffer tray member 200A3, and a convex portion 300AA projecting to the back side of the bottom surface is formed at the center. The width dimension of the part protruding in the front-rear direction in the convex portion 300AA is the left-right width dimension Z1, and the width dimension of the part protruding in the left-right direction is the front-rear width dimension Z2. A ridge line symbol W2 formed by intersecting the front and rear side walls 5A and the left and right side walls 2A is a locking portion that couples the middle buffer tray member 200A2 and the lower buffer tray member 200A3, and symbol W1 in FIG. Is seen from the back side. In the drawing of the buffer tray 200A shown in FIG. 8A, the longitudinal direction is referred to as front and rear, and the direction perpendicular thereto is referred to as right and left.

Next, a procedure for folding the accessory tray will be described. Based on the developed view of FIG. 2, the four side walls are erected from the bottom along the crease, and are shown in FIG. The front and rear side walls 2B are erected from the part of the fold line Q, and are bent from the part of the double fold line P so that the front and rear side walls 1B are inside. At the same time, the left and right side walls 5B are erected from the part of the fold line V, and the four corner side walls 4B are bent and erected from the part of the oblique fold line U. In this way, the four side walls rise up obliquely so as to surround the bottom surface 8B and rise so that the opening expands, forming the bowl-shaped accessory tray 200B, and forming the recess 300B in the center. At this time, the side wall 3B is sandwiched between the double side walls 1B and 2B, and at the same time, the projection 11B slightly protruding from the end of the front and rear side walls 1B is fitted into the locking groove 61B along the fold line Q. In this way, the four side walls and the four corner side walls are kept standing obliquely upward from the bottom surface. In the accessory tray 200B shown in FIG. 8, the longitudinal direction is referred to as front and rear, and the direction perpendicular thereto is referred to as left and right. On the bottom surface, the flap 6B near the front and rear side walls 1B of the bottom surface 8B rises from the crease R, and the flap 7B near the center rises from the fold S. Specifically, the end piece 72B is bent from the site of the crease S2 to the center side at a substantially right angle while the end piece 73B and the main piece 71B of the flap 7B are erected, and at the same time, the protrusion 74B slightly protruding from the end portion is formed on the bottom surface 8B. The flap 7B is stably held in a substantially upright state by being fitted and locked in the locking hole 81B. In this manner, an L-shaped side composed of the side side 731B, the upper side 711B, and the upper side 721B is formed by the front flap 7B. On the other hand, the rear flap 7B is substantially upright from the bottom surface, and L-shaped sides in opposite directions are formed facing each other. A pair of reverse L-shaped sides are formed by the front and rear flaps 7B and 7B near the center of the bottom surface 8B. Here, the left-right distance between the front side 731B and the rear side 731B in the pair of front and rear inverted L-shaped sides is based on the lateral width dimension Z1 of the protrusion of the protrusion 300AA of the buffer tray 200A. Slightly larger. Further, the distance between the front and back between the upper and lower L-shaped sides is slightly larger than the front-rear width dimension Z2 of the protruding portion of the convex portion 300AA of the buffer tray 200A (see FIG. 8).

Next, a state where the accessory tray and the buffer tray are wrapped in the outer box will be described with reference to FIG. First, the accessory tray 200B is placed on the bottom surface of the outer box 200C, the buffer tray 200A is placed thereon, and the upper buffer tray member 200A1 is placed at the center. In the outer box 200C, the accessory tray 200B is placed on the lower stage, and the buffer tray 200A is placed thereon. Next, the upper buffer tray member 200A1 is placed thereon, and the smartphone 96 is placed thereon, as shown in FIG. The procedure for storing accessories will be described later.

The packaging member is incorporated into the outer box as described above, and the operation or function of the main member will be described below.

In the development view of the buffer tray cardboard of the present embodiment, as shown in FIG. 1, the upper buffer tray cardboard, the lower buffer tray cardboard, and the middle buffer tray cardboard are connected vertically in a strip shape, and the whole is substantially rectangular. The size of the buffer tray cardboard in the present embodiment is compared with that of the conventional buffer tray cardboard (see FIG. 18) in FIG. The buffer tray cardboard 100A of this embodiment is shown on the left side of the figure, and the conventional buffer tray cardboard 100A ′ is shown on the right side. The impact tray corrugated cardboard of the present embodiment is long and connected in a strip shape, and has a generally rectangular shape. On the other hand, the conventional buffer tray corrugated cardboard has a different shape and is cut into four corners. Specifically, the maximum width dimension L2 of the conventional buffer tray cardboard is larger than the maximum width dimension L1 of the buffer tray cardboard of this embodiment. On the other hand, the longest dimension L4 of the conventional buffer tray corrugated cardboard is smaller than the dimension L3 of the present embodiment, but the conventional buffer tray corrugated cardboard is wasteful of the corrugated cardboard material because the ratio of the four corners removed to an irregular shape is large. Comparing the usage amount of the raw corrugated paper material before cutting out the buffer tray cardboard, the buffer tray of this embodiment can reduce the usage amount of the corrugated paper material by about 40% compared to the conventional case.

Next, the assembly efficiency of the buffer tray will be described. As shown in FIG. 5, a recess is provided in the center of the assembling jig 50, following the shape in which the bottom of the buffer tray 200 </ b> A protrudes. Further, the assembling jig 50 is provided with an outer contour 52 and an inner contour 53 having steps following the plurality of folds of the lower buffer tray cardboard 100A3 and the middle buffer tray cardboard 100A2. Therefore, when the lower buffer tray cardboard 100A3 is placed on the assembly jig 50 and pushed from above, the lower buffer tray cardboard 100A3 is instantly recessed following the outer contour 52 and the inner contour 53 having steps. Similarly, when the middle buffer tray cardboard 100A2 is placed thereon and pushed from above, it is immediately dented similarly. Therefore, the operator can instantly fold up the buffer tray 200A in which the buffer tray cardboards are stacked in two stages accurately without requiring skill. In contrast to the conventional assembly time of the buffer tray, which took 40 seconds, in this embodiment, half the time was 20 seconds.

Next, a mechanism for locking and coupling the lower buffer tray member 200A3 and the middle buffer tray member 200A2 when assembling the buffer tray will be described. FIG. 13 is an enlarged view of a symbol W1 portion that is a locking portion between the front and rear side walls 5A and the left and right side walls 2A in the buffer tray 200A shown in FIG. In addition, the state which looked at the symbol W1 part from the back side is shown as symbol W2 in FIG.8 (b) mentioned above. The acute wedge 51A (see the lower buffer tray cardboard 100A2 in FIG. 1) provided on the front and rear side walls 5A bites into the concave and obtuse corner 21A (see the middle buffer tray cardboard 100A3 in FIG. 1) provided on the side wall 2A. (Refer to the portion indicated by symbol W2 in FIG. 8B). In coupling the lower buffer tray member 200A3 and the middle buffer tray member 200A2, eight similar coupling mechanisms are provided. In addition, at the left and right ends, the rectangular locking piece 8A of the middle buffer tray member 200A2 is locked to the rectangular forward notch hole 4A of the lower buffer tray member 200A3. In this way, the sharp wedge portion 51A engages with the locking portion 21A at a total of eight locations, and the locking piece 8A engages with the notch hole 4A at two locations, whereby the lower buffer tray member 200A3. And the middle buffer tray member 200A2 are securely coupled and do not move up and down.

After inserting accessories into the accessory tray, the buffer tray is placed from above according to the shape of the recess at the center, and fitted. This stacked state is shown in FIG. 14, and the stacked heights of the product of this example and the conventional product are compared. The product of this example is shown on the left side, and the conventional product is shown on the right side. In this embodiment, the accessory tray 200B is placed on the lower side and the buffer tray 200A is placed thereon. On the other hand, the conventional product similarly has the accessory tray 200B 'on the lower side and the buffer tray 200A' on the lower side. It is what I put.
