The present invention relates to a portable compression bag and a method of manufacturing the same, and more particularly, since it is very reliably blocking external air from flowing into the compression bag. The present invention relates to a portable compression bag and a method of manufacturing the same, which can be maintained to facilitate use in a state where the volume of the compression bag is reduced in use, and at the same time keep the storage space of the compression bag at a minimum.

When traveling, clothes are put in a compression bag and rolled or pressed to compress internal air, and the compressed air containing the contents is put into a suitcase while reducing the volume of the compressed bag.

On the other hand, such a known compression bag, usually after opening the compression zipper and putting the contents such as clothes into the inside of the compression bag and sealing the compression zipper again, to discharge the internal air of the compression bag to the outside in order to reduce the volume of the compression bag possible Use the roll or press the bag with the contents to make it.

At this time, after the contents are put into operation, when the bag is compressed by rolling or pressing the bag in a sealed state by operating the compression zipper, the air inside the compression bag is provided in the bag and is discharged to the outside through the check valve described in detail below. .

In addition, the check valve provided in the compression bag discharges the internal air of the compression bag to the outside, but blocks the outside air from flowing into the compression bag.

That is, when the compression bag is used, the external discharge of the internal air is implemented through only the check valve, and for this purpose, the compression bag is sealed except for the check valve as a whole.

For example, FIGS. 1 to 4 illustrate a portable compression bag 300 having a conventional check valve 200.

That is, as shown in Figures 1 and 2, the outer shell 310 of a predetermined thickness to form the outer shape of the compression bag overlapping (2) or more, while sealing (for example, fusion through a hot wire) (S) can be put inside the contents. In the form of a bag 300.

And, as shown in Figure 1, one side of the outer shell 310 is not sealed, it is provided with a pressing zipper 320 that the user manipulates to open when the contents, such as clothing, and tightly sealed thereafter. .

In this case, the portion indicated by [S] in FIGS. 1 to 4 is a portion in which the outer shells 310 are integrally sealed to block aeration of air, and the valve plates 210 of the check valve 200 described below. And the outer shell 310 represent the integrally sealed portion.

Of course, since the outer shell 310 or the valve plates 210 of the check valve 200 are made of a thin synthetic resin sheet, they are preferably fusion-sealed through a heating wire.

Therefore, as shown in Figure 1, when using the conventional compression bag 300, first the user opens the compression zipper 320, through the contents of the garment, etc., and then operated the compression zipper 320 again (each Compresses the zipper) to seal the compression bag 300.

Then, as shown in FIGS. 3 and 4, when the compression bag 300 is rolled or pressed (when the bag is compressed), the air inside the compression bag 300 is between the outer shell 310 sealed to the opposite side of the compression zipper 320. The internal air is discharged to the outside through at least one check valve 200 provided in the.

At this time, through the check valve 200, the inflow of the compressed bag of the outside air is blocked so that the volume of the compressed bag is maintained in a compressed state.

On the other hand, Figure 3a is an enlarged view for explaining the ventilation state.

On the other hand, Figures 2 to 4 show the check valve 200 provided in the conventional compression bag 100 in detail.

For example, as shown in FIG. 3, the check valve 200 provided in the conventional compression bag 300, as described above briefly, is compressed when the contents are put in the compression bag, the internal air (' V1 'is discharged to the outside through the check valve 200, but the outside air (' V2 'of Figure 3a) is blocked without entering the inside of the compression bag 300 through the check valve (200).

That is, as shown in FIG. 4, the valve plates 210 of the check valve 200 made of a material having excellent elasticity are elongated at one end of the compression bag between the two layers of the outer skin 310 to be sealed.

At this time, in the part implementing the check valve 200, as shown in Figs. 2 and 4, the part forming the vent passage 220 to enable the ventilation of the internal air (V1) is the valve plate 210 and the shell 310 ) Is sealed (S '), the other remaining portion, that is, both sides of the passage 220 and the other valve plate 210 portion is sealed (S) integrally with the shell (310).

As described above, the portion indicated by [S] in FIGS. 1 to 4 represents a portion in which the outer shell and the valve plate of the outer shell and the check valve are fusion-sealed integrally, and the portion indicated by [S '] denotes a check valve ( As a part for installing the part 200, the part in which only the valve plate 210 adhered to the outer shell 310 and each other is sealed.

As a result, as shown in FIG. 3, the internal air V1 is discharged to the outside through the ventilation passage 220 of the check valve 200, but the external air V2 is the valve plate portion 210 that is not sealed to each other in the check valve. It is to be in close contact with the inside of the compression bag (300).

That is, the check valve 200 is to enable only one-way ventilation.

At this time, the manufacturing valve plate 210 is not installed only in the implementation portion of the check valve 200, but overlaps the valve plate 210 elongated to fit the length of the compression bag is interposed between the outer shell, install the check valve 200 In the part to seal only the valve plate and the outer shell and not sealing between the valve plate to implement the ventilation passage 220 therebetween, the other part is to seal.

However, the check valve 200 provided in the conventional compression bag 300, as shown in Figs. 2 to 4, because only the two-ply valve plate 210 overlaps, as shown in FIG. Likewise, it prevented the inflow of outside air, but its breathability did not last long.

As a result, in the case of the conventional compression bag 100, even when the clothes and the like are compressed to reduce the volume of the compression bag, external air flows into the compression bag through the ventilation passage 220 of the check valve 200 after a period of time. The original compressed volume of the compression bag was not maintained.

Accordingly, it would be desirable to increase the airflow blockage that completely blocks the inflow of the compressed air to the outside of the compressed bag without significantly changing the check valve structure of the compressed bag, since the compressed volume of the compressed bag is maintained intact over time. Portable compression bags have been required.

The present invention has been proposed in order to solve the above-described conventional problems, and the object of the present invention is to reliably block the inflow of external air into the compression bag, so that the contents of clothes and the like are stored inside the compression bag and compressed. The present invention provides a compression bag and a method of manufacturing the same, which can be maintained for a long time to facilitate use, and at the same time keep the storage space of the compression bag at a minimum.

As one technical aspect for achieving the above object, the present invention, the outer shell constituting the appearance of the bag while allowing the contents to be stored in a sealed state; And,

A ventilation control check valve provided at at least one location of the outer shell, the ventilation valve including a plurality of valve plates interposed between the outer shells to enable one-way ventilation and a plurality of ventilation blockers to block reverse ventilation;

It provides a compression bag configured to include.

In another aspect, the present invention, the step of continuously supplying each of the shells constituting the compression bag overlapping, supplying continuously while folding the unit valve plate to form a multi-breathing blocking between the shells; And,

Forming a check valve which forms a shell and a unit valve plate interposed therebetween with a compression bag, while at the same time only allowing one-way aeration in at least one portion of the shell;

It provides a compression bag manufacturing method comprising a.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

5 to 8 show a compression bag 100 according to the invention, for example a portable compression bag 100 having a characteristic airflow check valve 1 of the invention.

5 to 8, reference numerals corresponding to the conventional check valve 200 and the compression bag 300 are denoted by reference numerals of the check valve of 10 units and the compression bag of 100 units, and are the same as those of the conventional compression bag. The part is outlined in detail.

First, as shown in Figures 5 to 8, the compression bag 100 of the present invention, as described above, the opening and closing portion 100a through the sealing means 120 provided for the storage of the contents. Except for overlapping the sealing (S) and the outer shell 110, and provided with at least one place in the sealing portion of the outer shell, while being interposed between the outer shell 110 to allow only one-way ventilation is possible It is comprised including the check valve 1 for ventilation adjustment containing the several unit valve plate 10 provided in multiple.

That is, the compression bag 100 of the present invention, as in the prior art, by opening the sealing means 120, that is, the compression zipper to put the contents, such as clothing inside, and closing the sealing means 120, the compression bag 100 When compressed in a rolled or pressed form, the internal air (V1 of FIG. 7A) is discharged to the outside through the check valve 1 of the present invention described in detail below, and the inflow of the external air (V2 of FIG. 7A) is blocked. However, specifically, the structural improvement of the check valve 1 has its characteristics.

In this case, reference numeral [S] in FIG. 5 to FIG. 8 denotes a portion in which the outer shell 110 and the valve plate 10 are interposed and the portion in which the outer shell and the valve plate 10 are integrally sealed (fused). It is important to recognize that '] indicates a portion in which the outer shell 110 and the valve plate 10 are in contact with each other in the portion where the check valve 1 is installed, the portion sealed (fusion) with a predetermined width.

Therefore, as shown in FIGS. 6 and 7A, the ventilation passage 14 through which the internal air V1 is discharged to the outside between the valve plates 10 between the portions S ′ where only the portion in which the outer skin and the unit valve plate contact each other is sealed. ) Is formed.

On the other hand, as shown in Figures 6 to 8, the check valve 1 of the present invention is characterized in that the unit valve plate 10 is one valve plate is elongated corresponding to the length of the outer shell is folded different length (D1) It is interposed between outer shells, provided with the ventilation block | hole 12a (12b) of (D2).

Therefore, the check valve 1 of the present invention is different from the conventional check valve (200 of FIGS. 2 to 4), one unit valve plate 10 is interposed in two layers between the outer shell, while folding different lengths The ventilation block 12 (D1) of the (D1) and (D2), that is, the first and second, the ventilation block 12a (12b) is composed of multiple to block the inflow of outside air (V2 in Fig. 7b) more reliably There is a feature to that.

As a result, in the present invention, the unit valve plate 10 interposed in a plurality of layers, for example, in two layers, is interposed between the outer shell 110 that is double-sealed and sealed in two layers except for a portion in which the sealing means 120 is installed in two layers. 6 and 8 are actually provided to be elongated in accordance with the length of the outer shell, but only in the part where the check valve 1 is installed, the unit valve plate 10 (multiple ventilation cutout 12a) ( 12b)) and only each of the outer shell (110) in contact with each other (S ') and the multiple valve plate 10 is not sealed between it should be recognized that the ventilation passage 14 formed therebetween.

At this time, as can be seen in Figure 7a and 7b showing 'B1-B1' and 'B2-B2' in cross-section in Figure 6, respectively, the unit valve plate 10 for installing the check valve 1 is not sealed to each other Therefore, both side portions of the portion forming the ventilation passage 14 are sealed to block the ventilation integrally with the shell along the ventilation passage (S).

Therefore, when the compressed bag is actually used, as shown in FIG. 7A, when the contents T, for example, a garment is put into the compressed bag 100 and compressed, the inside air V1 is part of the vented path 14. When the compression of the compression bag is stopped while the expansion of the compression bag is stopped, the unit valve plate 10 is folded from the sealed check valve 1 except for the ventilation passage 14, while the force for discharging the internal air is lost. The vent block 12a, 12b of the plurality of unit valve plates having different lengths D1, D2, which are provided with each other, corresponds to a portion corresponding to each other, that is, the first vent block 12a and the second vent block ( 12b) are kept in close contact with each other so that the inflow of the outside air V2 into the compression bag is reliably blocked.

As a result, the compression bag of the present invention, since the check valve 1 enables multiple ventilation cutoffs as in the prior art, as shown in Figs. 3 and 7, the inflow of outside air into the compression bag is reliably blocked.

At this time, Figure 7a is an enlarged view for explaining the ventilation state, the unit valve plate 10 overlapped between the outer shell in which the actual check valve 1 is installed, both sides along the ventilation passage 14 as shown in Figure 7b Since the sealing (S), when the compression bag 100 is compressed when the internal air (V1) when passing through the outside expands up and down, and when the compression is stopped, the vent block 12a in contact with each other of the unit valve plate 10 12b are intimately in close contact with each other to block the inflow of the compressed bag of the outside air V2 in duplicate.

On the other hand, as shown in Figure 5, the compression bag 100 of the present invention is installed so that the sealing means 120, that is, the compression zipper is pressed against each other in a portion (110a) that is not sealed to one side of the outer shell to put clothes, such as during travel It comes in a portable compression bag for ease of use.

As a result, the compression bag 100 having the check valve 1 according to the present invention has a structure in which the check valve has a plurality of ventilation cutoff portions 12, that is, one valve plate 10, and the length of each other as shown in FIG. Intervening between the shells with the other ventilation blocking portions 12a and 12b formed therebetween, except for the portion where the check valve 1 is installed, the shell, the shell and the valve plates are integrally and non-ventilated sealing (S). In addition, only the portion where the check valve 1 is installed is sealed (S ') with only the valve plate and the outer shell, and the ventilation passage 14 is formed between the valve plates.

Therefore, the compression bag of the present invention corresponds to each other, since the internal air is discharged from the inside of the air vent block 12a (12b) to the outside, but the external air must pass through the air vent block 12a (12b). The inflow of the outside air is blocked by double by the multiple ventilation blocking parts 12a and 12b in close contact, thereby greatly improving the inflow of the outside air.

In particular, the check valve 1 provided in the compression bag of the present invention simply folds one flat unit valve plate 10 and interposes it between the outer shells, and since the other structure and manufacturing are the same as in the prior art, substantially blocking the air ventilation. Although excellent in performance, the structure is very simple, making the compression bag easier and less expensive than the effect.

At this time, although not shown in a separate drawing, if the reverse position of the vent block portion of the valve plate, if the air is filled inside the bag is completely sealed form, the internal air can be introduced but the external discharge of the internal air is blocked It may be possible to apply, for example, to the form of air rods.

Next, FIG. 9 illustrates a manufacturing step of the compression bag 100 having the check valve 1 according to the present invention.

That is, as shown in FIG. 9, first, the envelope 110 constituting the compression bag is continuously supplied in duplicate, and the unit valve plate 10 embodying the multiple ventilation cut-off portions 12a and 12b described above between the envelopes. ) Are fed between the sheaths while folding them continuously.

Then, the shell 110 and the unit valve plate 10 interposed therebetween are molded into a compression bag, while at the same time forming a check valve 1 to enable only one-way aeration of the compression bag.

Accordingly, the check valve 1 of the present invention is a multiple vent block 12a of different lengths (see D1 and D2 in FIG. 8) while only folding the flat valve plate 10 between the supplied shell 110. Interposed so as to form (12b), and then it can be produced very simply through the sealing and cutting steps as in the prior art.

In this case, as shown in FIG. 9, the outer shell is continuously supplied while the outer shell roll 110 'prepared according to the length of the compression bag is manufactured, and the outer shell is transported as shown in FIG. 9 in the roll 110' state. It is conveyed continuously through the rolls R.

Next, the unit valve plate 10, like the outer shell roll, through the guide roll (R '), which is released from the valve plate roll (10') and sequentially inclined, through the multiple (12a) (12b) ventilation blocker Folded to form (12) and fed continuously between the sheaths.

Therefore, since one flat unit valve plate is folded and interposed between the outer shells, the structure is not complicated in the manufacturing process, and only a guide roll R 'for supplying the valve plate while folding the valve plate is required.

At this time, it is important that the valve plate 10 has a roll shape in which the width of the valve plate 10 is adjusted in advance so as to be the length of the check valve 1 when the one end of the outer shell, that is, the sealing means (120 in FIG. 1) is folded to the other side which is not formed. It is wound.

In addition, the material of the valve plates installed as the outer shell and the check valve may be a known one, but a material having excellent adhesion strength in close contact with each other may be used because the valve plate for adjusting aeration is thinner than the outer shell.

Next, as shown in FIG. 9, the supplied outer shell 110 and a double layer unit valve plate 10 interposed therebetween are formed into a compression bag while forming a check valve 1. In the step, the sealing heating wire (not shown) and the compression zipper jig (not shown) of FIG. 9 have a jacket with a pair of forming means 410 suspended on the lower surface and the upper surface, and the valve plate therebetween. Is formed in one side of the outer shell and the sealing means 120 for sealing the outer shell in cooperation with each other to enable the storage of the contents by compressing the intervening portion in a folded state, and the check valve 1 is formed (S '). Except for the outer skin and the outer shell and the unit valve plate is integrally sealed (S).

At this time, the check valve (1) portion seals only the outer shell and the valve plate (S ') and does not seal between the valve plates, so that the ventilation passage 14 is formed therebetween, so the sealing degree of this portion must be precise, of course, In the same sealing, the check valve 200 portion of the conventional compression bag 300 may be processed using a well-known technique since only the valve plate and the outer shell seal.

Next, finally, the compression bag of FIG. 9 is cut to fit the size of the compression bag using a cutter 420 provided above and below the manufacturing line.

At this time, as described above, in the case of forming the check valve 1, except for the portion of the multiple vent block 12a, 12b of the valve plate which is folded between the outer shell and interposed therebetween, the check valve is provided. Sealing (S) integrally with the outer shell, the portion to install the check valve seals only the outer shell and the vent blocking portion (S ') to form a vent passage 14 between the vent blocking portion.

In particular, the ventilation blocking portion of the unit valve plate forming the ventilation passage 14 is sealed (S) on both sides integrally with the shell along the ventilation passage to enable the external discharge of the internal air, the compression of the compression bag 100 When the rolling or pressing operation is interrupted while the contents are put in, each of the multiple vent blocks of the multiple valve plate is in close contact with each other to reliably block the inflow of outside air.

According to the portable compression bag and the manufacturing method thereof of the present invention, since the outside air is very reliably blocked from entering the compression bag, the contents such as clothes and the like are kept in the portable compression bag for a long time. It can be used to provide convenience and at the same time provide an excellent effect of keeping the compression bag storage space to a minimum.

In particular, the check valve provided in the compression bag of the present invention simply folds one flat unit valve plate and interposes between the shells, and since the structure and fabrication of the structure are the same as in the prior art, the air valve is substantially excellent in air vent blocking, but the structure is very high. It is simply to provide other good effects compared to the effect, which makes compression bag fabrication easier and less expensive.

While the invention has been shown and described in connection with specific embodiments so far, it will be appreciated that the invention can be varied and modified without departing from the spirit or scope of the invention as set forth in the claims below. It will be appreciated that those skilled in the art can easily know.
