Down pockets, down products and methods of manufacturing down products using them

The present invention relates to a product using down, and more particularly, to a down pocket capable of stably filling down down parts of clothing or bedding, a down product using the same, and a method of manufacturing the down product.

Down, which is a duck or goose's hair, is widely used for clothing and bedding because of its excellent heat retention and lightness. Down is a mixture of duck and goose necks and chest hair and feathers. Generally, the ratio of hair to feather is 4: 1 or 9: 1, and the higher the ratio of hair is, the lighter and warmer, the more hair is used.

The down product has a structure in which down is filled in the down charging part. Unlike the down, the down is not agglomerated, and each one is independent, so if you use the down product for a long time, the down will be thrown to one side. In order to solve such a problem, the down product is divided into a plurality of down charging parts which can be charged down by sewing. When the down is charged to the down charging part of the down product, a down injection tool is used to blow down the down charging part at a constant pressure.

Hereinafter, with reference to the accompanying drawings will be described in detail an embodiment of the present invention. Down products include garments for which down can be used (down jumpers, vests, etc.), bedding (quilts, sleeping bags, pillows, etc.), sofas, handbags, and the like.

First embodiment

The down bag 60 for the down product according to the embodiment of the present invention, as shown in FIG. 1, comprises a down 64 and a bag body 62. The bag body 62 has an inner space 68 in which the down 64 can be filled, and when a predetermined pressure is applied, the bag body 62 expels the charged down 62 to the outside.

The material of the bag body 62 may be blown by a predetermined pressure, and there is little foreign matter even if it remains in the down filling part, and an insoluble material that does not dissolve or loosen in water may be used, or a water-soluble material that dissolves in water may be used. For example, a plastic material, a nonwoven fabric, a thin fabric, or the like, which includes a thin and flexible vinyl, may be used as the insoluble material. Functional materials such as ocher, jade, charcoal, elvan, amethyst and germanium may be added to the insoluble material.

As the water-soluble material may be used solvron (solvron) or biodegradable polyvinyl alcohol (polyvinyl alcohol). At this time, the reason why the water-soluble material is used as the material of the bag body 62, after inserting the down bag 60 in the down charging part of the down product and popped down to charge the down 64 to the down charging part, it remains in the down charging part. This is to remove the popped pocket body 62 from the down charging part easily through water washing.

On the other hand, the bag body 62 according to the first embodiment has been disclosed an example having a rectangular plate shape, but is not limited thereto. For example, the bag body 62 may have various shapes such as a polygonal plate, a disc, and a cylindrical shape.

When the down 64 is filled in the bag body 62, the bag body 62 is convex by the down 64. It is preferable to manufacture the down bag 60 smaller than the down packing part so that the down bag 60 can be stably inserted into the down packing part. It is preferable to pack the down 64 as densely as possible in the bag body 62 so that the down charging part can be filled with the down 64 filled in the small down bag 60 as compared to the down charging part.

Further, when a certain pressure is applied to the bag body 62, at least one unsealed line 66 is further added to the outer surface of the bag body 62 so that the bag body 62 can be blown out to discharge the charged down 64. Can be formed. Of course, if the bag body 62 can be burst by a certain pressure may not form the tear line 66.

The down bag 60 according to the first embodiment may be manufactured separately, or a plurality of the down bags 60 may be manufactured in a batch. In the case of separately manufacturing the down bag 60, the down bag 60 may be manufactured by sealing the inlet after filling the down 64 with the inlet in a state in which a bag body 62 having an inlet is formed on one side thereof.
