  DESCRIPTION OF EMBODIMENTS Hereinafter, an embodiment of a hanging packaging apparatus for articles according to the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 shows a thermoplastic synthetic resin thin film 1 according to a first embodiment of the same apparatus and an outer peripheral frame 2 on which the film 1 is covered. As shown in FIG. A plurality of adhesive portions of the bent portion 1b for engagement of the film 1 in a stretched state (a tensioned state) in which the flat surface 1a, which is one surface of the film 1, is slightly pulled (stretched) in the horizontal and vertical directions. 1 'is joined to the outer peripheral frame 2 with a hot melt adhesive or the like.

  The flat surface 1a is a flat surface of the film 1 as shown in FIG. 1. However, when the surface forms a slightly curved surface, or as shown in FIG. This is a concept including the case where the flat surface 1a is slightly curved upward by the upward projection 16 and the like.

  The thermoplastic synthetic resin thin film 1 is a very thin flexible film having a thickness of 10 μm to 300 μm, and the material thereof is a thin film transparent or translucent thermoplastic film such as polyethylene, polypropylene, polyurethane, polystyrene or the like. Used. In the following embodiments, the thickness of the thermoplastic synthetic resin thin film 1 is the same as described above even if not otherwise specified.

  As shown in FIG. 1, the film 1 has plasticity due to heat through a flat surface 1a ′ in which an article storage recess 3 of a rectangular parallelepiped-shaped article (for example, an electronic component such as a semiconductor) is formed on a flat surface 1a. A plurality are formed by deformation. In the embodiment of FIG. 1, five article storage recesses 3 are formed in two rows (a total of 10), but the number and shape of the recesses are arbitrary, and can be changed depending on the number and shape of articles to be stored. is there.

  Such a thermoplastic synthetic resin thin film 1 can be formed by the vacuum forming method shown in FIG. That is, a substantially rectangular parallelepiped mold 6 (see FIG. 4) in which a plurality of article storage recesses 4 are formed and a plurality of suction through holes 5 is formed is placed horizontally on a mesh plate 7, and the mold The thermoplastic synthetic resin thin film 1 heated and softened on the mold 6 is coated, and in this state, vacuum suction (arrow a) is performed through the suction through-hole 5 so that the article storage recess shown in FIG. A flexible thermoplastic synthetic resin thin film 1 having 3 can be formed.

  The film 1 molded by such a method has a flat surface 1a in which a plurality of flexible article storage recesses 3 are formed by plastic deformation, and a direction substantially orthogonal to the entire circumference of the periphery of the flat surface 1a (see FIG. In FIG. 1, a bending portion for engagement 1b that is flexible in the downward direction is integrally formed with the flat surface 1a by plastic deformation.

  Although this thermoplastic synthetic resin thin film 1 maintains the shape as shown in FIG. 1 after being molded, its thickness is extremely thin, so that it has flexibility as a whole and can be folded in two or It can be stored compactly by folding it in three, etc., and when it is stacked in the vertical direction as shown in FIG. 20, the bent portion 1b for engagement and the article storage recess 3 are compressed in an indefinite shape in the vertical direction. Even if a large number of films 1 are stacked, they can be stored and transported without being bulky. The concave portion 3 and the like are plastically deformed even after being compressed into an indefinite shape, so that the original shape is maintained, and there is no problem with storing the article.

  The outer peripheral frame 2 is formed by connecting a side plate 2b of a synthetic resin having a constant width in an annular shape, for example, a square shape (FIG. 1). When a transparent plate is used, the outer peripheral frame 2 is compatible with the transparent thermoplastic synthetic resin thin film 1. As a result, the electronic component stored in the article storage recess 3 can be visually confirmed, which is convenient for product inspection and the like. In addition, when transparency is not required, it may be formed by bending a band-like corrugated board having a constant width into a rectangular frame shape and joining the end portions.

  What is shown in FIG. 2 is the state which covered the outer periphery frame 2 with the thermoplastic synthetic resin thin film 1 comprised as mentioned above, and when the said film 1 is covered on the said outer periphery frame 2, the said film 1 is the The flat surface 1a is pulled (stretched) in the direction of the four sides around it (horizontal direction), and the flat surface 1a is in a tensioned state. And the outer periphery frame 2 and the said film 1 are joined by adhere | attaching the adhesion part 1 'of the bending part 1b for engagement of the said film 1 to the outer periphery frame 2 with a hot-melt-adhesive agent.

  The depth of the article storage recess 3 is formed to be about ½ of the height of the side plate 2b of the outer peripheral frame 2. Even when the outer peripheral frame 2 is mounted on the tray 8, the recess 3 and the tray A space S is formed between the bottom plate 8a and the bottom plate 8a (see FIGS. 6 and 26).

  8 is a rectangular parallelepiped tray (bottom tray with an upper surface opening) having an upper surface opening and a bottomed box. The tray 8 includes a bottom plate 8a and side plates 8b that erect in four directions, and an upright plate 9 is provided at the center along the longitudinal direction. It has been. The upright plate 9 supports the center of the back surface of the flat surface 1a of the film 1 when the outer peripheral frame 2 in the state where the film 1 is mounted is mounted on the tray 8, and curves downward to the flat surface 1a of the film 1. (Sagging) is prevented.

  Since the suspended packaging apparatus for articles according to the present invention is configured as described above, in order to configure the apparatus, the thermoplastic synthetic resin thin film 1 is placed on the outer peripheral frame 2 in the field, and hot melt bonding is performed. A plurality of portions (adhesive portion 1 ′) of the bent portion for engagement 1 b and the outer peripheral frame 2 are joined by an agent. Thereafter, the outer peripheral frame 2 with the film 1 mounted thereon may be covered so as to close the upper surface opening 8c of the tray 8 (see FIG. 5). At this time, the outer peripheral frame 2 is positioned outside the side plate 8b of the tray 8, and the outer peripheral frame 2 is mounted like a lid of the tray 8, but the outer peripheral frame 2 on which the film 1 is stretched is You may comprise so that it may accommodate in the side plate 8b inside of the tray 8. FIG. Thereafter, the electronic component 10 (semiconductor or the like) may be stored in each article storage recess 3 of the flat surface 1a of the film 1 with the outer peripheral frame 2 mounted on the tray 8 (see FIG. 6).

  When the electronic component 10 is stored in the article storage recess 3, as shown in FIG. 6, the electronic component 10 is stored with the film 1 in the flexible article storage recess 3 in close contact with the surface of the component, Further, since the space S exists between the article storage recess 3 and the bottom plate 8a of the tray 8, the electronic component 10 is stored in the film 1 in a suspended state.

  At this time, since the engaging bent portion 1b of the film 1 is adhered to the outer peripheral frame 2, even if the electronic component 10 is accommodated in all the article accommodating recesses 3, the film 1 is moved downward due to its weight. There is no deviation. Further, since the upright plate 9 is present at the center of the tray 8, the back surface of the central portion in the longitudinal direction of the flat surface 1a is supported by the upright plate 9 when the electronic component 10 is stored. Are supported in a suspended state by film surfaces (flat surfaces 1a, 1a ′) engaged with the upper edge 2a of the outer peripheral frame 2 and the upper edge 9a of the upright plate 9.

  The suspended packaging apparatus packaged in this way is stored in a truck or the like and transported alone or in a state of being stacked vertically. At this time, since each electronic component 10 is packaged in a suspended state by the thermoplastic synthetic resin thin film 1 as described above, even if vibration or the like occurs during transportation, the electronic component 10 may come into contact or collide anywhere. And can be transported safely. Therefore, the collision of the electronic component to the edge of the hole, which has been a concern when stored in the film recess formed in the perforated hole portion of the flat plate as in the prior art, cannot occur, and the electronic component 10 is suspended well. Can be buffer packed. The vibration direction during transportation occurs mainly in the same direction, and the intermediate flat portion 1a ′ is formed between the article housing recesses 3. Therefore, the electronic components in the article housing recesses 3 collide with each other during transportation. Cannot usually happen.

  Further, since the article storage recess 3 is formed so as to conform to the shape of the electronic component by plastic deformation, the film surface can be in close contact with the surface of the article 10 and the stored article 10 can be reliably supported. Since the article 10 is not displaced in the horizontal direction and the vertical direction due to vibration of the article, and the article storage recess 3 is provided with a constant distance via the flat surface 1a ′ of the film 1 at a predetermined interval, Even when a plurality of articles 10 are stored, the articles do not collide with each other. Therefore, it is possible to arrange the plurality of article storage recesses 3 close to each other, and while the plurality of articles can be stored, the packaging area can be reduced and the entire packaging apparatus can be downsized.

  FIG. 7A shows a state in which the thermoplastic synthetic resin thin film 1 is set on the outer peripheral frame 2, and a crease 2h (for example, a concave groove in the vertical direction) is formed at the center of the opposing side plate of the short piece of the outer peripheral frame 2. As shown in FIG. 2B, the side plate 2b is bent from the fold 2h in the facing direction (close direction) with the film 1 mounted, and the outer peripheral frame 2 is joined together with the thermoplastic synthetic resin thin film 1 together. It can be folded. At this time, as shown in FIG. 7A, the film 1 was attached to the outer peripheral frame 2 or the film 1 was attached to the outer peripheral frame 2 and both were bonded (adhesive portion 1 ′). In this state, the thermoplastic synthetic resin thin film 1 can be folded together by folding the outer peripheral frame 2 in the opposite direction from the fold 2h.

  If it does in this way, the outer periphery frame 2 and the said film 1 can be folded very compactly, for example, compared with the shaping | molding packaging material by the conventional hard plastic, area, such as the bulkiness at the time of the said packaging apparatus conveyance, is reduced significantly. This can greatly reduce the transportation cost of the suspended packaging apparatus.

  The connection of the thermoplastic synthetic resin thin film 1 and the outer peripheral frame 2 is not limited to the hot melt adhesive, and can be made by the following connection method.

  As shown in FIG. 8, the outer peripheral frame 2 is formed of a corrugated cardboard, and is provided with upward engaging projections 2d and 2d (projections) on each of the upper edges 2a of the two orthogonal sides of the right-angled corner portion 2c. The engaging protrusion 2d is bent along the upper edge 2a in the outer direction of the outer peripheral frame 2, and in this state, the bent portion 1b for engaging the thermoplastic synthetic resin thin film 1 is the outer surface 2d ′ of the engaging protrusion 2d. The outer peripheral frame 2 is covered so as to cover the outer periphery.

  In this way, the protrusion 2d tries to rotate and return in a direction spreading in the outer direction (arrow b direction), and therefore the end 2d '' of the protrusion 2d is engaged with the film 1 by the return force. Due to the engagement (joining) relationship between the projection 2d end 2d ″ and the film 1, it is possible to prevent the film 1 and the outer peripheral frame 2 from being displaced. A flexible engaging recess that can be fitted into the engaging protrusion 2d is formed in the engaging bent portion 1b by plastic deformation, and the engaging protrusion 2d and the engaging recess of the film 1 are formed. The film 1 and the outer peripheral frame 2 can be joined by fitting them together.

  The outer peripheral frame 2 can be formed of a plastic corrugated board, cardboard, etc. in addition to the corrugated board.

In the second embodiment, the same reference numerals are assigned to the same parts and corresponding parts as those in the first embodiment.

  In this embodiment, the thermoplastic synthetic resin thin film 1 (having a thickness of 10 μm to 300 μm as in the first embodiment) has the largest rectangular parallelepiped article storage recess 3 a corresponding to the camera body 11. A medium-sized rectangular parallelepiped-shaped article storage recess 3b corresponding to the AC adapter 11a and a small rectangular parallelepiped-shaped article storage recess 3c corresponding to the battery 11b are formed via a flat surface 1a 'in the middle of a predetermined interval. ing. The depths of the article storage recesses 3a to 3c are formed to be approximately 1/2 of the height of the engagement bent portion 1b.

  The thermoplastic synthetic resin thin film 1 having such a shape can be formed by the vacuum forming method shown in FIG. 10 as in the above embodiment. That is, a substantially rectangular parallelepiped mold 6 having a plurality of article storage recesses 4 and a plurality of suction through-holes 5 is placed horizontally on a mesh plate 7 and heated on the mold 6. The soft synthetic resin thin film 1 that has been softened is coated, and in that state, vacuum suction (arrow a) is performed through the suction through-hole 5 to thereby have article storage recesses 3a to 3c shown in FIG. A flexible thermoplastic synthetic resin thin film 1 can be formed. The film 1 molded by such a method has a flat surface 1a in which a plurality of flexible article storage recesses 3a to 3c are formed by plastic deformation, and a direction substantially orthogonal to the entire periphery of the periphery of the flat surface 1a. A bending portion for engagement 1b that is flexible (downward in FIG. 9) is formed integrally with the flat surface 1a by plastic deformation.

  The thermoplastic synthetic resin thin film 1 is formed with a relatively deep bent portion 1b for engagement, which is directed to the upper surface opening of the tray 8 with the upper surface opening and has the tray on the back side of the periphery of the flat surface 1a. 8 is covered until the upper edge 8h comes into contact, and the periphery of the bent portion 1b for engagement and the periphery of the side plate 8b of the tray 8 are linearly bonded with a hot melt adhesive or the like (the bonding portion is indicated by 1 ").

  Then, the digital camera body 11, the AC adapter 11a, and the battery 11b are stored in the article storage recesses 3a, 3b, and 3c, respectively. In such a storage state, the article storage recesses 3a to 3c are supported in a suspended state by the upper edge 8h of the tray 8, the flat surface 1a of the film 1, and the intermediate flat surface 1a 'between the recesses 3a to 3c. The Therefore, even if vibration or the like occurs during transportation, the above-mentioned stored article does not collide anywhere, and buffer packaging in a suspended state can be realized. Each article storage recess 3a to 3c is formed through an intermediate flat surface 1a ', and the articles stored in the recesses 3a to 3c are horizontally and vertically even if vibrations occur during transportation. There will be no shift and no collision will occur.
