Description

  The present invention relates to a packaging container.

As packaging containers for displaying merchandise accommodated in the store, for example, as described in Patent Document 1, a container having a merchandise container, and a rectangular tubular body covering the container (accommodating part) Are known. The packaging container disclosed in the same document is made of a transparent or translucent resin sheet with a rectangular cylindrical body, and the visibility of the product accommodated therein is good. It is suitable as a packaging container for displaying products.
Japanese Utility Model Publication No. 5-34120

  In the packaging container described in Patent Document 1, in order to accommodate the product in a predetermined manner, for example, as shown in FIGS. 10 (a) and 10 (b), the container 100 is substantially equal to the contour line of the product 110, and In some cases, the housing portion 101 having a depth substantially equal to the outer diameter of the product 110 is formed, a plurality of convex portions 102 are provided on the side wall surface of the housing portion 101, and the outer periphery of the product 110 is constrained by the convex portions 102. . However, when such a configuration is adopted, it is difficult to accurately recognize the product when the product is viewed in perspective due to the presence of the partition portion 103 that partitions and forms both the storage portions 101.

  Moreover, since the square cylindrical body described in Patent Document 1 is an assembly formed by bending a resin sheet punched out (cut out) into a predetermined shape, the workability at the time of packaging is poor. There is also. Furthermore, since this type of packaging container also functions as a protective material for protecting a product from a drop impact or the like, it needs to have a predetermined strength (impact resistance). However, in particular, when a predetermined strength is to be ensured for a rectangular tubular body that is a bent product (assembly product) of a resin sheet, a relatively thick resin sheet must be used, and the material cost increases. There is also.

  The present invention has been made in view of the above problems, and the object of the present invention is packaging in which the visibility of the product accommodated in the interior is good, the protection performance of the product is high, and the packaging operation is easy. It is to provide a container at a low cost.

  In order to solve the above-described problems, the present invention includes a lid member that has an opening and is thermoformed from a resin sheet, and a tray member that is detachably fitted to the opening of the lid member. A main body that supports a partial region in the circumferential direction of the product, and a tongue-shaped flap piece that is foldably provided at one end edge of the main body and is housed inside the lid member in a folded state to support one end of the product. A packaging container is provided.

  The term “thermoforming” as used in the present invention refers to a technique for obtaining a molded product having a predetermined shape by deforming a heat-softened resin sheet along a mold. Specifically, the resin sheet is obtained by vacuuming. Vacuum forming that deforms along the mold, compressed air forming that deforms the resin sheet along the mold by supplying compressed air, or combined use of vacuum drawing and compressed air supply along the mold This is a technique such as vacuum / compressed air forming.

  The packaging container according to the present invention includes a lid member and a tray member that is detachably fitted to the lid member. And in the packaging container which concerns on this invention, since a tray member has a main body which supports the circumferential direction partial area | region of a goods, and a flap piece which supports the end (for example, lower end) of goods in a bending state, it depends on a main body. It becomes possible to reduce the support area of the product. This means that it is possible to increase the exposed area of the product by forming the product support portion provided in the main body shallower than before, and thus the visibility at the time of perspective is improved. Such an operational effect can also be obtained, for example, by making the tray member an injection-molded product having an L-shaped cross section. In the present invention, the portion that supports one end of the product is a foldable flap piece. The member can be a thermoformed product that is inexpensive to manufacture.

  In addition, since the lid member is a thermoformed product thermoformed from a resin sheet, the assembly process of the lid member (square tubular body) required in the conventional configuration is not required, and the tray is placed in the opening of the lid member. The packaging operation can be completed simply by fitting the members. In general, since the strength and transparency of a resin sheet is improved by thermoforming (heating and stretching), the cover member is made using a resin sheet that is thinner and less transparent than conventional ones, while reducing the material cost. It is possible to ensure the strength and transparency required for the. As described above, according to the present invention, it is possible to provide a packaging container with good visibility of the product accommodated therein, high protection performance of the product, and easy packaging operation at low cost.

  It is desirable to provide the flap piece with a restraining portion that restrains the outer periphery of one end of the product. If it does in this way, it can control that goods move in the peripheral direction, without reducing the visibility of goods, and it becomes possible to support goods stably in a desired mode. In addition, a restraint part may restrain the outer periphery of the end of the goods over the perimeter, and may restrain a partial area | region of the circumferential direction. However, in the case of adopting the latter configuration, it is desirable to form the restraining portion in a form that can restrain the circumferential region different from the circumferential partial region of the product supported by the main body. If it does in this way, it will become possible to restrain the outer periphery of goods over the perimeter indirectly by cooperation of the support part of goods provided in the main part, and the restraint part provided in the flap piece. It is.

  The lid member can be provided with a regulating portion that regulates the opening operation of the folded flap piece. In this way, it is possible to effectively prevent the product from rattling in the axial direction inside the container and to support the product more stably.

  One end of the lid member can be provided with a leg portion that enables the packaging container to stand on its own. Thereby, the packaging container according to the present invention can be displayed and displayed in a self-supporting state. By the way, the independent display of packaging containers is generally performed at a position lower than the purchaser's line of sight. In such a case, the visibility of the product when the packaging container is displayed in the above-described manner can be improved by inclining the product support surface of the flap piece with respect to the bottom surface of the leg portion.

  The lid member and the tray member constituting the packaging container according to the present invention may be separate and independent members, or may be an integrally formed product. The former configuration is suitable when required physical properties (strength, color, etc.) are different between the lid member and the tray member, and the latter configuration is suitable when the required physical properties are common. In addition, if it is the latter structure, since both can be assembled | attached only by bend | folding either one of a cover member or a tray member to the other side, packaging work can be made still easier.

  As described above, according to the present invention, it is possible to provide a packaging container with good visibility of a product accommodated therein, high protection performance of the product, and easy packaging operation at low cost.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS.

  FIG. 1 is a perspective view showing a packaging container H according to the first embodiment of the present invention. The packaging container H shown in the figure is a packaging container for packaging a pair of products (decorative bottles) K1 and K2 having a perfect circular shape, and includes a lid member 1 having an opening 2 and an opening 2 of the lid member 1. And a tray member 10 that can be detachably fitted. In the vicinity of the opening 2 of the lid member 1, convex fitting portions 4 projecting inward are formed at four locations in the circumferential direction (only three locations are shown in FIG. 1). 4 and a recessed fitting portion 17 formed at four places in the circumferential direction of the tray member 10 (only three places are shown in FIG. 1), respectively, thereby the lid member 1 and the tray member 10 are They are integrated (the packaging container H is completed). A leg portion 3 for allowing the packaging container H to stand independently is provided at a substantially central portion in the width direction of one end of the lid member 1, and the packaging container H as a finished product can be displayed in a state where it is self-supporting on a display shelf or the like. It has become. In the following description, the side on which the legs 3 are provided is the lower side, and the side opposite to the axial direction is the upper side.

  In this embodiment, the tray member 10 is a molded product thermoformed from a resin sheet made of polyethylene terephthalate (PET), and bulges from the back side to the front side as shown in FIGS. A main part is constituted by the main body 11 formed as described above and a tongue-like flap piece 21 provided at the lower end edge of the main body 11 so as to be bendable. On the back surface of the main body 11 (strictly speaking, the back surface of the step portion 18 to be described later), a mount 30 on which detailed information of the product is described is fixed (adhesive fixing). In addition, the resin sheet used for shaping | molding of the tray member 10 can be used regardless of transparent, semi-transparent, and non-transparent, and can be suitably changed according to a request | requirement.

  The main body 11 is retracted by a predetermined amount toward the back side, and defines a partitioning portion 12 that partitions and forms first support portions 13 and 14 that respectively support partial regions in the circumferential direction of the products K1 and K2, and from the periphery of the partitioning portion 12 to the back side. And a flange portion 19 extending outward from the peripheral edge of the peripheral wall portion 16 through a minute step portion 18. As shown in FIG. 2 (a), the first support portion 13 has a cross-sectional shape that substantially follows the contour line of the product K1, while the depth of each portion (retreat amount to the back side) is the product. It is set sufficiently smaller than the outer diameter of each part of K1. The same applies to the first support portion 14 that supports the product K2. Therefore, most of the products K1 and K2 in the circumferential direction are exposed to the outside of the partition portion 12 in a state where the products K1 and K2 are accommodated in the first support portions 13 and 14, respectively. Each of the first support portions 13 and 14 is provided with one or a plurality (two in the illustrated example) of concave portions 15 that are further retracted toward the back side. The bottom part of each concave-shaped part 15 is located on the same plane as the one end on the back side of the peripheral wall part 16, thereby increasing the bonding area with the mount 30 that is bonded and fixed to the back face of the main body 11. .

  Of the lower edge of the main body 11, the width direction area where the first support portions 13, 14 are provided is set back by a predetermined amount, and the products K 1, K 2 are accommodated (placed) on the first support portions 13, 14, respectively. ), The products K1 and K2 protrude downward from the lower end edge of the main body 11 by a predetermined amount. On the other hand, the folded flap piece 21 is accommodated in the retracted portion. When the flap piece 21 is folded, the lower end of the main body 11 is positioned below the lower end of the flap piece 21. It is like that.

  The flap piece 21 is provided with second support portions 22 and 22 that support the lower ends of the products K1 and K2 in a bent state, respectively, spaced apart in the width direction. On the outer periphery of each second support portion 22, a standing portion 22 a is provided that stands from the second support portion 22 and defines the second support portion 22. In this embodiment, the standing portion 22 a is provided. Is formed in an arc shape in plan view. On each standing portion 22a, minute protrusions 22b projecting inward are formed at a plurality of circumferential locations (five locations in the illustrated example) at equal intervals (60 ° intervals). The inner diameter dimension between the protrusions 22b facing each other by 180 ° is set to be slightly smaller than the outer diameter dimension of the products K1, K2, and the lower end of the products K1, K2 is bent by the second support portion 22 by folding the flap piece 21. When supported, the outer peripheral surfaces of the lower ends of the products K1, K2 are constrained and held by the inner periphery of each standing portion 22a. That is, in the present embodiment, the standing portion 22a and the plurality of protrusions 22b provided thereon function as the restraining portion in the present invention. Of course, the form of the restraining portion is not limited to this, and can be appropriately changed depending on the shape of the product.

  The connecting portion 20 between the main body 11 and the flap piece 21 has a perforated through-hole extending in the width direction of the tray member 10 in order to facilitate the folding of the flap piece 21 (to enable repeated folding). A hole is formed. The means for facilitating the folding of the flap piece 21 to be formed in the connecting portion 20 is not limited to the perforated through-hole, and may be a ridge (fold) or the like.

  The manufacturing method of the tray member 10 having the above configuration will be described in detail below.

  FIG. 3 is a side view conceptually showing a main part of the forming device 40 of the tray member 10. In the figure, a PET resin sheet 42 is fed out from an original fabric roll 41 arranged on the left side of the figure. The resin sheet 42 is sequentially fed to a molding machine 50, an intermediate puncher (not shown) and a trimming machine by a conveying means (not shown), and the tray member 10 as a finished product is obtained at a stage where the resin sheet 42 is discharged from the trimming machine.

  The molding machine 50 is a vacuum molding machine in which a main part is constituted by a heating part 51 and a molding part 52. The heating unit 51 is for heating and softening the resin sheet 42 to an appropriate molding temperature, and a heater (not shown) is arranged above or below the conveyance path. The resin sheet 42 heated and softened to an appropriate molding temperature by the heating unit 51 is transferred to the molding unit 52. The molding unit 52 uses a molding die in which mold parts for molding various irregularities to be provided on the tray member 10 are continuously arranged at predetermined intervals in the sheet feeding direction and the width direction. The irregularities in the columns are molded into the resin sheet 42. The molding machine 50 is not limited to a vacuum molding machine, and may be a pressure molding machine or a vacuum / pressure molding machine.

  The resin sheet 42 on which many irregularities are molded is transferred to the play portion 43 and temporarily stays in a slack state. This absorbs the shift in cycle time between the molding machine 50 that forms the double-row, double-column irregularities on the resin sheet 42 in one shot and the subsequent machines that process only one row in the sheet feed direction in one shot. Is done. Next, the resin sheet 42 is transferred to an intermediate puncher (not shown), and the intermediate puncher facilitates the folding of the flap piece 21 at a position corresponding to the connection portion 20 between the main body 11 of the tray member 10 and the flap piece 21. The perforated through hole is formed. Thereafter, the resin sheet 42 is transferred to a trimming machine, and each finished product (tray member 10) is obtained by trimming the resin sheet 42 into a predetermined shape with the trimming machine. On the other hand, the trimmed resin sheet 42 is wound around a scrap winder (not shown). During mass production, the above operations are continuously performed in parallel, and the tray member 10 is continuously formed.

  As shown in FIGS. 4A and 4B, the lid member 1 is formed so as to bulge from the back side to the front side and has an opening 2 on the back side. This is a thermoformed product thermoformed from a translucent PET resin sheet. An outwardly extending flange portion 6 is formed on the periphery of the opening 2, and this flange portion 6 engages with a step portion 18 of the tray member 10 when the lid member 1 and the tray member 10 are fitted. (See FIG. 6). The bulging amount of the lid member 1 is substantially equal over the entire length in the axial direction, and thus the front portion 7 is formed on a flat end surface parallel to the axis. A leg part 3 for allowing the packaging container H to stand independently is provided at a substantially central part in the width direction of the lower end of the lid member 1, and the leg part 3 is bent on both sides in the width direction when the tray member 10 is fitted. Restricting portions 5 and 5 for restricting the opening operation of the flap piece 21 are provided. The peripheral wall 8 extending from the peripheral edge of the front portion 7 to the back side includes the leg portion 3 and the regulating portion 5, taking into account the releasability during thermoforming, as a whole, the inner diameter dimension (opening) from the back side to the front side (Dimension) is gradually reduced.

  Since the manufacturing method of the cover member 1 is based on the manufacturing method of the tray member 10, detailed description is abbreviate | omitted. However, the intermediate puncher is unnecessary in the apparatus for forming the tray member 10 according to the present embodiment.

  The lid member 1 having the above configuration and the tray member 10 are assembled as follows. First, after the products K1 and K2 are received (placed) in a predetermined manner on the first support portions 13 and 14 provided on the main body 11 of the tray member 10, the flap pieces 21 are bent and the lower end surfaces of the products K1 and K2 The second support portions 22 and 22 are brought into contact with each other. Thus, when the 2nd support part 22 is made to contact | abut to the lower end surface of each goods K1, K2, as mentioned above, the circumferential direction partial area | region of the lower end outer peripheral surface of each goods K1, K2 will become a restraint part (several protrusions). 22b). More specifically, as shown in FIG. 5, the axial portion excluding the lower end portion of the product K <b> 1 (the portion protruding downward from the lower end edge of the main body 11) has a partial region in the circumferential direction of the first support portion. On the other hand, the lower end portion of the product K1 is restrained and held by the restraining portion (protrusion 22b) of the flap piece 21 at least in the circumferential direction partial region excluding the region supported by the first support portion 13. In other words, the product K1 is formed on the entire circumference by the cooperation of the first support portion 13 provided on the main body 11 and the restraining portions (the standing portions 22a and the plurality of protrusions 22b provided on the same) provided on the flap piece 21. It is restrained and held over. The same applies to the product K2. Thereby, the circumferential movement of the products K1, K2 is restricted, and the products K1, K2 can be stably supported in a predetermined manner.

  Next, when the tray member 10 in this state is fitted into the opening 2 of the lid member 1 and the tray member 10 and the lid member 1 are integrated, the products K1 and K2 are accommodated therein as shown in FIG. The packaging container H is completed. In the packaging container H as a finished product, the lower end surface on the front side of the flap piece 21 of the tray member 10 (in other words, the lower end surface on the rear side) and the regulating portion 5 provided on the lid member 1 abut. Thereby, in the self-supporting state as shown in the figure, the opening operation of the flap piece 21 is effectively prevented, and the products K1, K2 can be stably supported in a desired manner.

  As described above, in the packaging container H according to the present invention, the tray member 10 which is one constituent member of the packaging container H has a main body 11 supporting a partial region in the circumferential direction of the products K1 and K2, and a lower end edge of the main body 11. A bendable flap piece 21 is provided, and the lower end of the products K1, K2 is supported by the flap piece 21. Therefore, the support area of the products K1 and K2 by the tray member main body 11 can be made smaller than the conventional configuration shown in FIG. 10, that is, the depth of the first support portions 13 and 14 provided in the main body 11 can be reduced. It becomes possible. Thereby, since the exposed areas of the products K1 and K2 are increased as compared with the conventional products, the visibility of the products is improved particularly in a perspective view.

  The above-described effects can also be obtained by making the tray member an injection-molded product having, for example, an L-shaped cross section. In the present invention, the portion that supports the lower ends of the products K1 and K2 can be bent. Since it consists of the piece 21, the tray member 10 can be made into thermoformed goods, such as vacuum forming whose manufacturing cost is cheaper than injection molding.

  In addition, since the lid member 1 is a molded product thermoformed from a transparent or translucent resin sheet, an assembly process of the lid member (square tubular body) which is essential in the manufacturing process of the packaging container shown in Patent Document 1. Becomes unnecessary, and the packaging operation can be completed only by fitting the tray member 10 into the opening 2 of the lid member 1. In general, the resin sheet is improved in strength and transparency by thermoforming. Therefore, even if the lid member is manufactured using a resin sheet that is thinner and less transparent than the conventional one, the strength and transparency required for the lid member can be ensured, and the material cost can be reduced. .

  Further, in this embodiment, as shown in FIG. 2A, since the mount 3 is fixed to the back surface of the tray member 10, the rigidity (particularly torsional rigidity) of the tray member 10 and the packaging container H is improved. And the self-supporting stability of the packaging container H can be enhanced.

  7 to 9 show a packaging container H according to a second embodiment of the present invention. Hereinafter, the second embodiment will be described, but the configuration according to the first embodiment described above is denoted by a common reference number, and redundant description will be omitted as much as possible, and different configurations will be described in detail. .

  7 (a), 7 (b) and 8 (a), 8 (b) are respectively a left side view and a front view of the tray member 10 and the lid member 1 constituting the packaging container H according to the second embodiment of the present invention. It is. In this embodiment, as shown in FIG. 7A, the retreating amount of each part of the first support portions 13 and 14 provided on the tray member 10 toward the back side is shown in FIG. 2A. Are set substantially the same as each other, and the extension dimension of the peripheral wall portion 16 extending from the peripheral edge of the partition portion 12 to the back surface side is gradually increased from the upper end edge side toward the lower end edge side. Therefore, in the state where each product K1, K2 is accommodated (placed) in the first support portions 13, 14, the amount of projection of the product K1 (K2 is omitted for convenience) from the partitioning portion 12 to the front side is the first. While the same as that of the first embodiment, the axis of the product K1 is inclined by a predetermined amount with respect to the back surface of the tray member 10. As is clear from FIG. 8A, the front surface 7 of the lid member 1 is inclined by a predetermined amount with respect to the rear surface in a manner corresponding to the inclination of the product K1.

  When the tray member 10 and the lid member 1 are configured as described above, when the packaging container H is self-exhibited by assembling both, the product K2 (K1 is omitted for convenience) as shown in FIG. The support surface (second support portion 22) of the flap piece 21 that supports the lower end is inclined by a predetermined amount with respect to the bottom surface of the leg portion 3 provided on the lid member 1. Thereby, the product K2 is displayed in a state where it is inclined by a predetermined amount with respect to the axis of the packaging container H. In this way, for example, even when this type of packaging container H is displayed and displayed below the purchaser's line of sight, it is possible to appropriately inform the purchaser of the product mode. . Further, in this case, since the contact area between the restricting portion 5 provided on the lid member 1 and the bottom surface of the flap piece 21 is increased, the opening operation of the flap piece 21 can be prevented more effectively, and the product can be made more stable. Can be supported.

  As is clear from FIG. 7B, in this embodiment, the standing portion 22a provided on the flap piece 21 is formed in an annular shape, but the same configuration is adopted in the first embodiment described above. Is possible. The reverse is also true.

  Further, in FIG. 7A, the mount 30 shown in FIG. 2A is not shown, but in the present embodiment, the mount 30 may be fixed to the back surface of the tray member 10.

  In the above description, the packaging container H in which the separated and independent lid member 1 and the tray member 10 are assembled has been described. In the packaging container H according to the present invention, the lid member 1 and the tray member 10 are integrally formed in advance. It may be a thing. Such a configuration can be obtained, for example, by connecting the upper edge or side edge of the lid member 1 shown in FIG. 4 to the upper edge or side edge of the tray member 10 shown in FIG. . In this configuration, when the physical properties (strength, color, etc.) required by the lid member 1 and the tray member 10 are common, only one of the lid member 1 or the tray member 10 is bent to the other side. Since the assembly can be completed by the above, it is preferable from the viewpoint of facilitating the packaging operation.

  In the above description, the packaging container H composed of the lid member 1 and the tray member 10 thermoformed with a PET resin sheet has been described. However, the resin sheet that can be used for molding the lid member 1 and the tray member 10 is as follows. It is not necessarily limited to this, For example, it is also possible to use the resin sheet which consists of a polypropylene (PP), biodegradable resin, etc.

  In the above description, the packaging container H for product packaging having a perfect circular cross section has been described. However, the packaging container H according to the present invention is suitable even when packaging products having other cross sectional shapes. Of course, it can be adopted.
