である。 Technical Field The present invention relates to stuffed products such as cushions, futons, etc., which are compressed and wrapped in packaging materials, and particularly relates to stuffed products that are compressed and wrapped in packaging material for long periods of time. The present invention relates to a stuffed package that has a small amount of air flow and also has a small amount of natural air inflow. Prior Art and its Problems Since cotton-filled products contain a large amount of air, many proposals for compression packaging have been made for a long time due to distribution issues. Currently, the most commonly used method is to put the product in a plastic bag, compress it, and then put it in a bag or bag with the same volume as the compressed volume to prevent the product from becoming larger than the compressed volume. However, this method requires a lot of effort and has the problem of causing many wrinkles in the product. In addition, if the product is compressed in the thickness direction and packaged as in the present invention, there will be fewer wrinkles and less effort, and the product will look better, but the thickness of the product will be greatly reduced. Instead, air naturally entered and returned to its original size, making it impossible to compress and pack it, making it impractical. Purpose of the present invention The present invention solves these problems and provides a stuffed product with good resistance to settling, no wrinkles, and less natural air inflow. Composition of the present invention The present invention is a stuffed package consisting of a stuffed product and a packaging material for wrapping the stuffed product in a state in which the stuffed product is compressed in the thickness direction. Polyester fibers are mainly used for the filling, and the single fibers constituting the filling are opened and wrapped in a cloth in a three-dimensionally randomly arranged state, while at least one layer of the packaging material is made of polyamide. It is composed of a film material with a thickness of 50 μm or more and has two or more layers, and is formed to be 10 mm or more larger on each plane periphery than the planar size of the above-mentioned stuffed product, and the above-mentioned stuffed product is This is a stuffed package characterized in that the films of the packaging material are wrapped around each other in a state in which the packaging material is compressed and housed within the packaging material. The present invention will be explained in more detail below. Packed cotton products are sufficiently effective if the filling is made of fibers, such as cushions, pillows, and futons. However, in the commonly used filling material manufactured using the card method, the single fibers are arranged in a plane in the thickness direction of the product, so there is a large amount of "settling" in vacuum compression packaging. cannot be used. For this reason, a material in which single fibers having good resistance to settling are randomly arranged in a three-dimensional direction is used. In order to obtain the product,
This is possible by sufficiently opening the fibers and then packing them into a covering fabric using an air flow. The constituting fibers are mainly polyester fibers with little "settling", but they may also be used in combination with synthetic fibers such as acrylic and polyolefin, or natural fibers. In order to further improve the resistance to sagging, a sufficient effect can be obtained by applying silicone resin to the surface of single fibers to reduce entanglement between the fibers and increase smoothness. Further, the effect will be further improved if the single fibers are made hollow to increase the bulkiness even with the same filling weight and maintain the bulk when the package is opened. The thickness of the single fiber used depends on the texture of the stuffed product,
From the viewpoint of fatigue etc., 15 denier or less is preferable.
In addition, the shorter the length of the cut fibers, the better the finished product will be without unevenness, since the fibers will be packed together by the air flow. Preferably, it is cut to 80 mm to 20 mm. The covering fabric may be any of fibers, knitted fabrics, non-woven fabrics, etc., but it is preferable to use woven fabrics from the viewpoints of product size, form stability, and processability. When using fibers that make up the filling that are thinner than 5 denier or coated with silicone resin, in products using the conventional card method,
A so-called "wadding" phenomenon occurs in which the filling fibers come out through the fabric. For this purpose, dense and expensive fabrics must be used. However, this is not necessary according to the method adopted in the present invention of randomly orienting in three-dimensional directions using airflow. In the case of the conventional card method, JIS: L
−1096 When measured using the Frazier type test method prescribed in Method A of Air Aeration Measurement, if the air flow is not 5 c.c./cm ² /sec or less, the problem of “wadding” occurs, but according to this method, There is no problem even if it is 5 c.c./cm ² /sec or more. In fact, a large amount of ventilation is better, since a small amount of ventilation will make it difficult to get stuffed. However, if the ventilation rate is too large, it becomes uneven during packing and also causes the problem of "wadding", which is undesirable, and a good range is 6 c.c.
cm ² /sec to 40 c.c./cm ² /sec. The stuffed product with the above structure is packaged using packaging material.At this time, in order to rationalize distribution, store space, etc., compression packaging is used as has been proposed in the past. The amount is compressed by 70 or more, preferably 80 to 95 when the total volume is 100. Note that if it is 70 or less, there is little merit considering the time and cost of packaging. Furthermore, there are roughly two types of means for compressing stuffed products. That is, the planar method compresses in the thickness direction, and the three-dimensional method compresses in the width and length directions. The former product does not have wrinkles but has a large amount of settling, while the latter product has wrinkles but has little amount of settling. In the present invention, as mentioned above, sufficient consideration has been given to resistance to sagging, and a planar method with high product value is adopted. Use film-like packaging materials. Moreover, it is best to use a transparent material so that the color and pattern of the filling product can be seen. Commonly used polypropylene
A single film such as polyethylene is undesirable due to its high gas permeability, and is also easily damaged by contact with objects during distribution, resulting in what is called a "puncture" when air gets inside. Therefore, in the present invention, this problem is solved by using a polyamide film with high flexibility and airtightness in combination with adhesive. Further, the film needs to have a thickness of 50 μm or more, and if it is less than this, it cannot be used because it is easily punctured by contact with objects. Preferably, one having a thickness of 60 to 100 μm is used. Then, this film is formed into a bag shape, and after filling the bag with stuffed product, it is compressed or the air is actively removed and packed. At this time, the size of the bag must be at least 10 mm larger on each side than the size of the stuffed product when compressed. If it is smaller than this, the stuffed product will fly out during compression work and cannot be processed.
On the other hand, if the diameter is too large, the cost will increase, so it is preferable to increase the diameter by about 15 to 20 mm. After compressing the stuffed product by at least 70% as described above, seal the film. There are various sealing methods such as adhesive, high frequency, heat, etc. Basically, any method may be used, but heat is preferred from the viewpoint of reliability, cost, and durability. The seal width must be at least 5 mm; if it is less than this, air will gradually enter during long-term packaging, resulting in punctures. The preferred seal width is 5 to 10 mm. Furthermore, one example of the present invention will be explained with reference to the drawings. FIG. 1 is a perspective view showing an embodiment of the stuffed packaging according to the present invention. The stuffed product 2 is packed in a compressed state with the packaging material 1 and hermetically bonded at the adhesive part 3. FIG. 2 is a sectional view showing an embodiment of the stuffed packaging according to the present invention. The fibers constituting the filling 4 of the stuffed cotton product are not arranged in a plane, but are randomly arranged in three-dimensional directions to form the fabric 5.
is covered with. Further, it is packed in a compressed state with a packaging material 1 and hermetically bonded with an adhesive part 3. Effects of the present invention The specific configuration and effects of the present invention will be explained based on examples. Example As a stuffing product, raw polyester cotton with a thickness of 6 denier, a cut length of 40 mm, a hollow ratio of 25%, and a silicone resin applied to the fiber surface was used for the fibers constituting the filling, and after opening it, it was air-filled. The fibers are separated into lumps by the flow and placed in a bag-like fabric measuring 43cm x 43cm.
A cushion product was made by packing 300g/piece.
At this time, the bag-like fabric used as the fabric was
At 100%, the ventilation amount is 25 c.c./cm ² /sec. Then, when 1000 pieces of this cushion product were made and the thickness was measured, the average thickness was 25 cm/piece. On the other hand, using the conventional card method, polyester fibers of 6 denier, 64 mm cut, and processed with silicone resin are placed on a 43 cm fabric side fabric with an air permeability of 2 c.c./cm ² /sec.
We made 1,000 cushions containing 300g in each 43cm size, and measured the thickness of each cushion.The average thickness of each cushion was 20cm. Furthermore, in order to create the product of the present invention, a 48 cm bag was created using a film composed of three layers. This three-layer film consists of polypropylene, polyamide, and polypropylene layers glued together in this order.
The thickness is 80μm. Then, the cushion used in the present invention described above is placed in this bag-shaped film, compressed with a compressor so that the compression becomes 90%, and the opening of the film is bonded to a width of 5 mm using thermal adhesive. A cotton-filled package was created based on the idea. On the other hand, as a conventional product, the thickness is 20μm.
The conventional cushion was placed in a 48 cm bag made of polypropylene film, and the bag was similarly sealed with an adhesive width of 3 mm to prepare a conventional stuffed package A. At this time, I tried compressing a cushion and a film bag of almost the same size, but when I compressed it, the cushion itself flew out as well as the air, making it impossible to complete the entire operation. Furthermore, as a conventional product, package B of the following standard is also available.
Created 1000 pieces. The stuffed product had the same specifications as the present invention, and the film was placed in a polyethylene 30 μm bag with a size of 50 cm x 50 cm, compressed using the three-dimensional method, and then placed in a bag with the same volume as the compressed size. The above three types of stuffed packages were left for one month and the puncture rate, thickness, etc. were measured. The results are shown in Table 1, and the product of the present invention has excellent results and is a product with no problems at all even if it is put on the market.
