2a and 2b is a view showing the configuration of a compression pack 100 according to a preferred embodiment of the present invention.

As shown in these figures, the compression pack 100 according to a preferred embodiment of the present invention forms an opening O through which the stock is drawn in or drawn out. The compression pack 100 includes a first wrapping paper 110 and a second wrapping paper 120 to which the edge region 115 except for the opening O is coupled to each other. Here, one of the first wrapping paper 110 and the second wrapping paper 120 is provided with an air outlet 160 for discharging the air inside.

The wrapping papers 110 and 120 of the compression pack 100 according to the preferred embodiment of the present invention may be prepared by adhering the stretched nylon film A and the nylon film D as shown in FIG. 3A. Here, the adhesive (B) for bonding the stretched nylon film (A) and the nylon film (D) may be used by melting epoxy resin or polyethylene (PE).

Stretched nylon film (A) is produced by stretching the general nylon film 2 to 7 times by inserting the normal nylon film (D) between the two rollers to rotate opposite to each other by applying a tensile force in both directions. This is for printing by stretching in advance when the printing roller is pressurized nylon film is increased by the pressing force of the printing roller by the inherent elongation of the nylon film. In other words, when the nylon film is stretched in advance as much as it is stretched by the pressure of the printing roller coated with the dye, printing can be performed clearly and clearly. Here, the degree of stretching the stretched nylon film may be appropriately set in consideration of the size and durability of the compression pack 100 and the pressing force of the printing roller used in forming the printing surface.

Packaging material according to a preferred embodiment of the present invention (110, 120) is preferably used to stretch the general nylon film 6-7 times. This is because the printability is not good when the nylon film is stretched less than 6 times to form the stretched nylon film, and when the stretched film is larger than 7 times, the durability of the stretched nylon film may be easily torn off.

On the other hand, when the wrapping paper (110, 120) according to the present invention is formed of only the stretched nylon film (A) compared to the wrapping paper formed of the nylon film (D), the strength is weakened easily when inserting a bulky storage such as a blanket Can be torn. Therefore, the nylon film (D) is bonded to the stretched nylon film (A) to reinforce the strength of the stretched nylon film (A).

Here, when the thickness of the stretched nylon film (A) and the nylon film (D) is about 1: 2 or about 1.5: 2, it is preferable in consideration of material ratio and strength.

On the other hand, the stretched nylon film (A) forms a printing surface (P) on the bonding surface (B) with the nylon film (D) as shown in Figure 3b. This is to prevent the print surface (P) is exposed to the outside because it is in contact with the user's hand or the storage during use and can easily damage the paint or dye.

In this case, polypropylene film (LLPDE) may also be used to reinforce the strength of the stretched nylon film, and the printed surface may be provided on the stretched nylon film (A).

On the other hand, the wrapper 110 ', 120' according to the second embodiment of the present invention forms a projection (m) on the contact surface of the nylon film (D ') in contact with the storage as shown in Figure 3c. The protrusion m forms a moving path of air when the storage is filled in the wrapping paper 110 'and 120' through the opening O and the air is discharged through the air outlet 160. do. That is, the air may move through the space n between the protrusion m and the neighboring protrusion m so that the air inside the compression pack 100 may be completely discharged through the air outlet 160. As a result, the volume of the compression pack 100 may be minimized, thereby simplifying portability.

Here, the projection (m) may be provided in a polygonal shape, including a circular, and the narrower the distance between the projection (m) and the neighboring projection (m) is preferable because the volume of the air movement path is formed more. .

On the other hand, the wrapping paper (110 ″, 120 ″) according to the third embodiment of the present invention is an opaque film (E) between the stretched nylon film (A) and the nylon film (D ') having projections, as shown in Figure 3d This may be included. The opaque film E may be provided between the stretched nylon film A and the adhesive B, or may be provided between the adhesive film B and the nylon film D '. The opaque film E prevents the storage stored in the compression pack 100 from being identified from the outside. As a result, when the user moves the compression pack 100 to the outside, the internal storage cannot be easily identified and privacy can be protected. In addition, when the opaque film is used, the strength of the wrapping paper 110 ″ and 120 ″ may be reinforced.

Here, the non-transparent material (E) may be used for the nonwoven fabric. In addition, the opaque material (E) may be used in conjunction with several sheets. The more the opaque material (E) is used, the more difficult it is for the user to recognize the inside, so the number of opaque materials (E) can be adjusted according to the usage.

In addition, the opaque material (E) may be a fiber of a mesh structure. The strength of the first wrapping paper 110 and the second wrapping paper 120 is increased by the irregularly intertwined fibrous tissue may not be easily torn.

On the other hand, the first wrapping paper 110 and the second wrapping paper 120 according to the present invention in consideration of the use and manufacturing cost, such as the wrapping paper (110, 120) corresponding to the first to third embodiments described above It can use in combination suitably.

Here, the zipper groove 133 is provided between the zippers 133a and 133b protruding from each other. The zipper 130 is moved and coupled to each other by a zipper clip 140 to press the zipper protrusion 131 to accommodate the zipper groove 133.

Here, the zipper 130 according to a preferred embodiment of the present invention is provided with a separation prevention jaw 150 to prevent the outer separation of the zipper clip 140 as shown in Figure 2a and Figure 4 at both ends. The departure prevention jaw 150 applies heat to the edges of the first wrapping paper 110 and the second wrapping paper 120 and cools to form the sealing region 115, and thus does not cool only the departure preventing jaw 150. It is formed to have a higher height (h2) than the portion.

Here, the height h2 of the release prevention jaw 150 is higher than the height that the zipper clip 140 can be elastically separated to the outside of the compression pack 100 when the user applies a force as shown in FIG. It is preferable to provide, and to provide a lower than the height (h1) of the zipper clip. In addition, the length of the separation prevention step 150 is preferably formed to be the same or shorter than the length of the zipper clip (140).

On the other hand, the corner region (L) of the wrapping paper 110, 120 according to the present invention can be rounded to prevent injury to the user during use.

As described above, since the compression pack 100 according to the preferred embodiment of the present invention forms a printing surface on the stretched nylon film, printing can be made clearly.

In addition, the compression pack according to the present invention can not easily recognize the internal storage from the outside, including a non-woven fabric can protect the privacy of the user.
