Description

[Detailed description of the invention] [Industrial field of application] The present invention is mainly used for the underlay and intermediate cushioning material or the top layer covering cushioning when various fruits are stacked and packed in boxes such as cardboard boxes and wooden boxes. This invention relates to packaging cushioning materials used as materials, etc.

[Conventional technology and its problems] Traditionally, when perishable fruits such as apples, pears, peaches, and melons were stacked and packed in cardboard boxes or wooden boxes, the fruits were usually stored in trays made of foamed plastic. In this state, the layers are stacked with an intermediate cushioning material having a cushioning property interposed between each layer.

Single-corrugated cardboard, which has traditionally been used as an intermediate cushioning material for packaging the fruits mentioned above, has poor cushioning properties and air permeability, especially for fruits that have a core at the top, such as apples. In recent years, the use of a mesh made of flexible synthetic resin foam has been considered. (Utility Model Publication No. 55-18310), or inserting cardboard or the like as a core material into a cylindrical mesh made of foam (Utility Model Publication No. 47-37914), or polystyrene-based A laminated sheet of a foamed resin sheet and a foamed polyolefin resin sheet (Japanese Utility Model Publication No. 143229/1983) is commonly used.

However, the above-mentioned cushioning materials are only intended to be used as cushioning materials for packaging, and after individual fruits are taken out at retail stores, they are simply disposed of as unnecessary items, making disposal extremely troublesome. It has become large and uneconomical.

On the other hand, at retail stores, fruits transported from the production area are usually removed from cardboard boxes and packaged in cushioning bags, and recently, synthetic resin foam has been used for this packaging. Bags made of net-like material are often used (for example, Japanese Utility Model Application Publications No. 114641/1982 and Japanese Utility Model Publication No. 31256/1983), but such bags must be purchased separately.

In view of the above, the present invention is a packaging cushioning material made of a mesh of synthetic resin foam with good cushioning properties.
To provide something that can be suitably used as an underlay and intermediate cushioning material in box packaging of fruits, etc., and after use, the net-like material can be easily and effectively used as a packaging bag for individual fruits with cushioning properties in retail stores, etc. This is what I am trying to do.

[Means for Solving the Problems] In order to solve the above problems, the packaging cushioning material of the present invention is a net-like material made of synthetic resin foam, and a plurality of bags are separably connected. It is characterized by consisting of connected bodies.

[Function] The packaging cushioning material of the present invention having the above structure has the following features:
When fruits such as apples, pears, and peaches are stored in trays and stacked and packaged in a cardboard box, the cushioning material of this invention can be used alone or by overlapping with a base sheet such as corrugated paper to provide intermediate cushioning. When used as a material, an underlay cushioning material, or a top layer covering cushioning material, the mesh material is made of synthetic resin foam, so it has elasticity unique to foam and has excellent space retention. It is a concatenation of multiple bags and has a double structure on the front and back, which gives it thickness and elasticity, and together with this, it has extremely excellent cushioning properties, as well as the air permeability necessary for fruit packaging. It will also be excellent.

Not only that, but especially for the cushioning material of the present invention,
Since the net-like material is composed of a connected body in which a plurality of bags of the net-like material are connected in a separable manner, the net-like material can be easily separated into individual bags after being used as an intermediate cushioning material for boxing and packaging as described above. Furthermore, this bag has the elasticity and stretchability unique to foam netting, making it easy to open, and by storing each fruit taken out from the box at a retail store, etc., it has cushioning properties. It can be effectively used as a packaging bag.

[Example] Next, an example of the present invention will be described based on the drawings.
Reference numeral 1 indicates a packaging cushioning material according to the present invention, which is a flexible net-like material made of synthetic resin foam, and is composed of a connecting body 3 in which a plurality of bags 2 are separably connected. Examples of the flexible synthetic resin foam net include polyolefin resins such as polyethylene and polypropylene, styrene-ethylene copolymers, ethylene-vinyl acetate copolymers, and other relatively flexible thermoplastics. A net-like object made of plastic resin foam, made by crisscrossing a large number of strips of the foam vertically, horizontally or diagonally and fusing them together, or a net-like object formed by other means. The net-like material can be used to construct a bag and a connected body of the bag.

Each of the embodiments shown in FIG. 1 (FIG. 2), FIG. 3, and FIG. A case where the bag 2 is detachably attached to the bag 2 is illustrated. In the embodiment shown in FIGS. 1 and 2, the bag is constructed by stacking two net-like sheets 5, 5 on the front and back, and forming the desired width on both opposite sides and the central portion in both vertical and horizontal directions. Fused with 6
a, 6b and the fused part 6b at the center thereof.
A perforation-like cut 4 is formed in the center of the frame so that it can be separated at the cut 4, and in FIG. FIG. 4 shows a case in which a perforation-like cut 4 is made in the middle of the bag, and a perforation-like cut 4 is made in the middle so that each bag 2, which is fused vertically and horizontally at required intervals, can be separated into each bag 2. Notch 4
This shows the case where . In addition, various other forms of connection are possible, and in particular, as shown in FIG. 5, a plurality of bags 2 may be formed in a horizontally continuous manner so that a plurality of fruits can be packaged at the same time. It can also be carried out.

Further, in the embodiment shown in FIG. 6, the bag connector 3 is constructed in such a way that a plurality of individually formed bags 2 are arranged in parallel and can be separated in a continuous manner using appropriate connecting means. As the connection means mentioned above, in addition to partially overlapping the sides of the bags and fusing them so that they can be separated, other connection means such as adhesive tape may be used as long as they can be easily separated. You can also do that. In addition, as the bag form mentioned above,
There are various types, such as those with the bottom and both side edges fused together as shown in the figure, those with the bottom of a cylindrical mesh sheet fused together, and those with both sides of the bottom fused diagonally to form a square bottom. It is possible to implement it in the shape of a bag.

The bag 2 or bag link 3 made of the above-mentioned net-like material is manufactured in the same way as when manufacturing a normal bag.
In addition to overlapping two net-like sheets cut to a long length or a required length and fusing them to form a bag 2 with one side open, or a concatenated body 3 of multiple bags,
As shown in FIG. 7, a reticulated sheet 5' extruded into a cylindrical shape with a desired diameter is cut or cuttable into a length corresponding to a single bag, and one cut end is heat-sealed ( (not shown), or for example, as shown in FIG. 8, a plurality of bags 2 may be heat-sealed by a heating element 7 and cut by a cutter 8 so as to form a connection body 3 that can be separated into a plurality of bags 2 through cuts 4. . In addition, by utilizing the method for manufacturing bags using foamed sheets previously filed by the present applicant (Japanese Patent Application No. 53-92134), a connected structure of bags that can be separated or separated bag by bag from a long net-like sheet is produced. (not shown). Of course, various other implementations are possible.

As shown in FIG. 9, the packaging cushioning material 1 of the present invention having the above-mentioned configuration includes 10 fruits such as apples, pears, and peaches, 10 trays made of synthetic resin foam, etc.
2 and used as an underlay, intermediate cushioning material, covering cushioning material, etc. when stacking and packing in a box 11 such as a cardboard box.In this case, the cushioning material 1 of the present invention can also be used alone. Usually, taking shape retention and pressure resistance into consideration, single-sided corrugated paper or double-sided corrugated paper with appropriate shape retention and cushioning properties, styrene resin, polyolefin resin, etc. A cushioning sheet 9 made of a foamed synthetic resin sheet or a foamed sheet with wavy irregularities, etc., and the cushioning material 1 of the present invention are overlapped and used in such a manner that the cushioning material 1 is brought into contact with a fruit 10. In particular, the cushioning material 1 may be releasably attached to the cushioning sheet 9.

Since the cushioning material 1 of the present invention is made of a net-like material of synthetic resin foam and has a double structure that can be configured into a bag, it has sufficient thickness as an intermediate cushioning material, etc., and has good breathability and elasticity. It has an extremely excellent buffering and protective effect. Moreover, since it is made up of a connected body 3 of a plurality of bags 2 that can be separated, when each fruit taken out from a box is individually packaged at a retail store, etc., the cushioning material of the present invention can be used as an intermediate cushioning material, etc. By taking out the bags 1 and separating them appropriately, each bag 2 can be used as a cushioning packaging bag by storing fruits individually in each bag 2 as shown in FIG.

[Effects of the invention] As described above, the packaging cushioning material of the present invention can have sufficient thickness and space retention as an underlay, intermediate cushioning material, or top layer covering cushioning material when stacking and packaging fruits. Not only does it have excellent cushioning properties, it also has good breathability and feel to the touch.
Since the net-like material made of synthetic resin foam is formed so that it can be used as multiple bags, instead of being disposed of as is at retail stores, it can be effectively used as packaging bags with cushioning properties for individual fruit packages. This eliminates the waste of separately purchasing packaging bags, eliminates the need for troublesome processing work, and is extremely economical.
