Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the technical field of a package integrally formed of a synthetic resin sheet.
The present invention relates to a package that can easily package an object to be packaged with good buffering properties. 2. Description of the Related Art Conventionally, as an article to be packaged, for example, an HDD
When packaging products such as (hard disk drives),
The product 1 is inserted and housed in a plurality of product housing holes 71 provided in a synthetic resin packaging body 70 as shown in FIG.
Since the product accommodation hole 71 penetrates from the top surface to the bottom surface of the packaging body 70, the top surface and the bottom surface of the packaging body 70 are covered with an upper lid 60 and a bottom lid 70, respectively. It was put in and packed. However, in a package using the packaging body 70 provided with a plurality of product accommodation holes 71 as described above, the product 1 is packaged in a plurality of units. The number of demands for the product 1 and the number of packages do not always match.
Therefore, if the product 1 is packaged according to the demand, there are a number of product accommodation holes 71 in which the product 1 is not stored in the packaging main body 70, resulting in wasteful space and poor storage efficiency. There was a problem of becoming. Further, since the packaging body 70 itself is relatively large compared to the product 1 to be packaged, there is a problem that a large space is required to store the packaging body 70 before packaging the product 1. [0005] On the other hand, products are wrapped one by one with a wrapping sheet such as a foamed resin sheet or a non-foamed resin sheet having countless circular projections formed. Since it is necessary to stop in a packaged state so as not to be unraveled, there is a problem that packaging is extremely troublesome, and that the cushioning protection for the top surface of the packaged product or the like may be insufficient. The present invention has been made in order to solve the above-mentioned problems, and an object of the present invention is to provide a package which can be easily packaged with good buffering properties one by one. [0007] The package of the present invention is integrally formed of a synthetic resin sheet as a whole, and a side piece, a bottom piece, and a side piece are sequentially formed in the longitudinal direction of the sheet. Are formed so as to be freely bendable with each other, and the both-side pieces are bent so as to face each other to form a packaged article storage portion surrounded by a bottom piece and both-side pieces.
The bottom piece has a bellows portion, and the both side pieces are, at corresponding positions, a storage recess capable of storing the end of the packaged object, and a bottom piece of the outer side surface of the storage recess. A rib protruding from an outer side surface on a desired side, and a flange formed on a side opposite to a side coupled to the bottom piece via the housing recess , and the package is stacked To
The ribs of the upper package on the collar of the lower package.
It is characterized by engaging . Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a plan view showing a package according to an embodiment of the present invention, FIG. 2 is a cross-sectional view taken along the line II-II in FIG. 1, and FIG. FIG. 4 is a perspective view showing the side piece 30 in a slightly bent state, FIG. 4 is a cross-sectional view showing the package in a state where the package 1 is packaged, and FIG. Of stacked packages (stacked state)
FIG. As shown in FIG. 1, the package according to the present embodiment has a rectangular shape in which a foamed polyethylene terephthalate (PET) resin sheet is integrally formed by a sheet forming means such as vacuum forming. It is. This package body has, in the longitudinal direction of the sheet, an elongated side piece 10 having a relatively narrow width and a square bottom piece 2 having a relatively wide width.
The side piece 30 having the same shape as the side piece 10 is integrally connected to each other via a folding curve 50. Then, as shown by arrows in FIG. 2, when the both-side pieces 10 and 30 are bent at a substantially right angle to the front side of the sheet so as to face each other, the packaged object 1 surrounded by the bottom piece 20 and the both-side pieces 10 and 30. Is formed. The bottom piece 20 has a bellows portion 21 composed of a plurality of V grooves 22 provided in a direction perpendicular to the longitudinal direction of the sheet.
Are formed. The bellows portion 21 is formed by connecting five V-shaped grooves 22 so that the cross-sectional shape in the longitudinal direction of the sheet becomes jagged. In addition, wedge-shaped cuts 23 are provided at both ends of each V-groove 22. The bottom piece 20 can be easily expanded and contracted in the longitudinal direction of the sheet by the bellows portion 21 as described above, and can be bent relatively easily in the vertical direction. Further, by providing wedge-shaped cuts 23 at both ends of the V-shaped groove 22, the elasticity of the bellows portion 21 is further improved. In addition, the bellows part 21 in the illustrated present embodiment has five V-grooves 2.
2, but may be formed in an appropriate number as long as the elasticity can be secured in the longitudinal direction of the sheet.
The wedge-shaped cuts 23 provided at both end portions of the 2 may not be particularly provided. The side pieces 10 and 30 have a symmetrical shape as shown in FIG. 1, and have recesses 11 and 31 for accommodating the ends of the packaged article 1 at corresponding locations. And ribs 12 and 32 formed on the outer side surface of the storage recesses 11 and 31 on the side where the bottom piece 20 is desired, and flanges 13 and 13 formed on the peripheral edge portion corresponding to the short side portion of the sheet.
33. The receiving recesses 11 and 31 are formed so as to occupy substantially the entire side pieces 10 and 30 each having a rectangular shape. The storage recesses 11 and 31 are formed in a rectangular shape. However, if the end shape of the article to be packaged 1 is rounded, the bottom shape of the storage recesses 11 and 31 is rounded. What is necessary is just to form it in the shape along the external shape of the packaged article 1. Further, rectangular recesses 14 and 34 are formed at the bottoms of the housing recesses 11 and 31. When the side pieces 10 and 30 are bent to form the storage section A of the packaged article 1, the recesses 14 and 34 become convex ridges projecting outward.
Therefore, a good buffering property against stress from the lateral direction is secured. The ribs 12, 32 are provided in the housing recesses 11, 3,
The bottom piece 20 is formed integrally with the housing recesses 11 and 31 from the upper surface of the bottom piece 20 so as to protrude from the outer side surface of the housing 1. When the ribs 12 and 32 are viewed from the upper surface of the bottom piece 20, the ribs 12 and 32 are in a depressed state integrally with the accommodation recesses 11 and 31, and the upper surface portion of the bottom piece 20 and the inside of the accommodation recesses 11 and 31 are open. Ribs 12, 32 desired from the upper surface of the bottom piece 20
Is formed shallower than the bottom surfaces of the housing recesses 11 and 31. Also, at the opening desired from the upper surface of the bottom piece 20 of the ribs 12, 32, U-shaped cuts 16, 36 are formed in the U-shaped portion along the bottom piece 20 (see FIG. 3). Thereby, when the side pieces 10 and 30 are bent, the rib 32 is cut off from the bottom piece 20 and integrated with the accommodation recess 31 as shown in FIG. Then, when the side pieces 10 and 30 are bent at substantially right angles, the ribs 12 and 32 are in a state of being protruded at the bottom of the package as shown in FIG. The ribs 12 and 32 are provided on both sides of the pieces 10, 30.
Are formed, but the number may be determined as appropriate, such as one or three, and the shape may be a rectangular shape as shown in the figure. However, the shape can be appropriately formed, such as a chevron shape or a semi-cylindrical shape. On the side surfaces of the housing recesses 11 and 31 facing the ribs 12 and 32, there are formed two convex ridges 15 and 35 which are pushed in from outside and project into the housing recesses 11 and 31. The ridges 15, 35 are accommodated in the accommodation recesses 11, 3,
When the end of the article to be packaged 1 is inserted into the package 1, the package 1 comes into contact with the package 1 and is supported in a restrained state so that the end does not rattle. The number, shape, and the like of the ridges 15, 35 can be arbitrarily determined. The flanges 13, 33 are formed so as to travel upward from the upper surface of the sheet by draw forming from the short side of the sheet to the periphery thereof (see FIG. 3). The length of the flanges 13 and 33 is set substantially equal to the distance from one outer end of the two adjacent ribs 12 and 32 to the other outer end. Therefore, when the stacking state (stacking state) as shown in FIG.
2 can be engaged with the flanges 13 and 33 of the lower package just to prevent the side pieces 10 and 30 of the lower package from trying to open. The shapes and structures of the flange portions 13 and 33 have both the effect of preventing the opening of the side pieces 10 and 30 from opening and the increase in the pressure resistance during stacking as shown in FIG. When the object to be packaged 1 such as an HDD is packaged in the package according to the present embodiment configured as described above, first, the object to be packaged 1 is placed on the package in the state shown in FIG. Then, both side pieces 10 and 30 are bent upward until they are substantially perpendicular. At this time, the side pieces 10 and 30 do not need to be bent at the same time, and may be bent one by one. Then, both ends of the packaged object 1 are
The articles to be packaged 1 are accommodated in the accommodating recesses 11 and 31 of 0, 30 and are accommodated in the accommodating section A surrounded by the bottom piece 20 and the side pieces 10, 30 (see FIG. 4). As described above, in the package according to the present embodiment, the article to be packaged 1 can be easily packaged simply by bending the side pieces 10 and 30, and the bellows portion 21 formed on the bottom piece 20 has a bellows portion 21. Since the sheet expands and contracts in the longitudinal direction, the end of the article to be packaged 1 can be easily inserted into the accommodation recesses 11 and 31 without any trouble, and therefore, there is an effect that the packaging operation can be performed very easily. In the package according to the present embodiment, since the packaged objects 1 are wrapped one by one, they can be packed and shipped in a cardboard box or the like according to the number of demands. There is an effect that the storage efficiency can be improved by saving unnecessary space unnecessarily. Further, in the packaged state of the packaged article 1, there is an effect that the cushioning property of the bottom surface portion of the packaged article 1 can be sufficiently secured by the bellows portion 21 of the bottom piece 20. Further, in the stacked state as shown in FIG. 5, the bellows portion 21 on the upper side is interposed between the upper and lower packages 1 so that the cushioning property of the upper surface portion of the lower package 1 can be secured well. There is also an effect. Furthermore, both ends of the packaged object 1 are
1, the ribs 12 and 32 and the recesses 14 and 34 projecting from the housing recesses 11 and 31 have an effect that the cushioning property can be ensured well. Further, the ridges 15 and 35 formed in the receiving recesses 11 and 31 can firmly hold the end of the article 1 to be packaged, and furthermore, the shrinkage action of the bellows 21 is added. There is an effect that the nature is also good. In the stack state shown in FIG. 5, the ribs 12 and 3 of the upper package are
2 can be engaged with the flanges 13 and 33 of the lower package just to prevent the side pieces 10 and 30 from opening in the lower package, and can be prevented from being separated one by one. There is an effect that the packing state can be improved in the stacked state. On the other hand, the whole package according to the present embodiment is obtained by integrally molding a synthetic resin sheet.
The pre-packaged packages can be stacked along each other's shape, which has the effect of reducing the storage space of the pre-packaged package.
In the present embodiment, the article to be packaged 1 is packaged as it is, but the article to be packaged 1 may be covered with a thin sheet or the like for packaging. In this embodiment, a foamed PET resin sheet is used as the material of the package, but various kinds of foamed or non-foamed synthetic resin sheets conventionally used as a packaging material can be used. In addition to PET, polystyrene, polyethylene, polypropylene and the like can be mentioned. In addition, these synthetic resin sheets can be coated with various synthetic resin films and used, and furthermore, the synthetic resin sheet can be used with an antistatic treatment to prevent dust and dirt from adhering. In this case, packaging costs can be reduced by eliminating the antistatic bag. Further, in addition to the HDD described above, the packaged object 1 can be applied to various precision instruments, electric appliances such as small radios, toys, ceramics, glass products, and the like. In this case, the present invention is applicable even if the surface of the article to be packaged 1 is slightly uneven. As described above, according to the package of the present invention, the side piece, the bottom piece, and the side piece are coupled to each other so as to be freely bent.
Since the recesses are formed on both sides of the package to accommodate both ends of the packaged object, the packaged product is placed on the package, and the both sides are bent upward to a substantially right angle to form the packaged package. Both ends of the object are accommodated in the accommodating recesses of the side pieces, respectively, and the article to be packaged is accommodated in the accommodating portion surrounded by the bottom piece and the side pieces. In this way, the object to be packaged can be easily packaged simply by bending the pieces on both sides, and the bellows formed on the bottom piece expands and contracts, so that the end of the object to be packaged can be easily placed in the accommodation recess without any trouble. Therefore, there is an effect that the packaging operation can be performed very easily. Further, since the package of the present invention wraps the items to be packaged one by one, it can be packed and shipped in a cardboard box or the like according to the number of demands, and can be unnecessarily stored in the cardboard box. There is an effect that the storage efficiency can be improved without wasting space. Further, according to the package of the present invention, in the packaged state of the article to be packaged, the bottom surface of the article to be packaged has an effect that the bellows of the bottom piece can provide a good buffering property. In this case, there is also an effect that the bellows on the upper side is interposed between the upper and lower packages, so that the cushioning property of the upper surface of the lower package can be sufficiently secured. Further, both ends of the packaged object are covered with the accommodation recesses, and the ribs protruding from the accommodation recesses have the effect of ensuring the cushioning property. Further, according to the package of the present invention, there is an effect that the packing property of the article to be packaged can be improved by the shrinkage action of the bellows portion of the bottom piece, and the ribs of the upper package in the stacked state. However, it is possible to prevent the both side pieces of the lower package from opening just by engaging with the flange portion of the lower package, and it is possible to further improve the wrapping property than in the single state. is there. Furthermore, since the package of the present invention is obtained by integrally molding a synthetic resin sheet as a whole, the packages before packaging can be stacked in accordance with each other's shape. Thus, there is an effect that the space for storing the package before packaging can be reduced.
