In this packaging container, a transparent window 11 is formed so that the inside of the rice can be observed from the outside. This container must go through several processes to make the transparent window. First, the through-hole for the transparent window is perforated on the opaque sheet 12 on which the trademark, address, advertisement, and the like are printed, and then the transparent sheet 13 is laminated to block the perforated through-hole with the transparent sheet 13. Thereafter, the first sheet on which the transparent window is formed and the second sheet without the transparent window are sealed on three sides to form an adhesive part 16, and the contents (eg, rice, barley, sorghum, etc.) are put into the non-glued opening 17. Sealed to the opening 17 is sealed. Sealing is a method that the sheets are fused by heat pressing. Depending on the type of contents, vent holes may be made.

Also shown in FIG. 2 is a sealed container 20 used for packing kimchi, etc., which is a packing container formed with an opening 27 at one side by sealing two sheets 22 and 23 at three edges 24. . The vessel 20 may have a built-in getter 21 for absorbing the gas generated when the contents are fermented. When the packaging container 20 is made, the sealer 26 is formed to insert the getter 21 manually and to be attached to the inside. In addition, abnormal fermentation may occur due to the bacteria on the hand, and the getter insertion method needs to be improved.

It has a second sealing space 116 between. Even in this case, the opening 117 is sealed after the contents are inserted.

This bag has two storage spaces, so you can pack the main products and the paper products together for convenience.                     

In addition, the sealed packaging container 120 of the present invention, as shown in Figure 7, the first sheet 121, the second sheet 122, and the third sheet 123 laminated to form a packaging container and And a sealing means having a grooved receiving portion 128 and an inserting portion 129 having a rail inserted into and resiliently coupled to the groove, the edges of the first sheet and the third sheet corresponding to each other. One of the receiving portion and the inserting portion of the sealing means is exclusively bonded to each other, and joins the edges of the first sheet and the second sheet while including the sealing means attached to the first sheet and the third sheet therein. The adhesive portion 124 is formed, so that the space 126-1 between the third and second sheets is used as a disposable sealed space, and the space 126-2 between the first and third sheets has a plurality of openings and closings. It is configured to be used as possible closed space.

The packaging container with such a zipper can be closed to some extent even after opening the sealed package, so that it can be sealed to some extent, so that the contents to be sealed can be put in a separate space, which is convenient.

In addition, the sealed packaging container 130 of the present invention, as schematically shown in Figure 8, between the first sheet 131 and the second sheet 132 for forming the packaging container, and between the first and second sheets Attaching the first sheet 131 and the portion 136 of the third sheet so that the third sheet 133 inserted therein and the pocket 135 having the edges of the third sheet as the inlet 134. It includes a pocket 135 formed to open a portion of the third sheet. This pocket may be formed by adhering a third sheet to the second sheet. In the figure, the content 138 inserted in the pocket 135 indicates the getter.                     

The sealed packaging container 150 of the present invention, as schematically shown in Figure 9, the first sheet 151, the second sheet 152, and the third sheet 153 laminated to form a packaging container The vertical adhesive portion 157 is formed by adhering the longitudinal edges of the first, second, and third sheets to each other, and the first and second sheets 151 and the third sheet are bonded to each other so that the horizontal edges are formed at different positions. The first horizontal adhesive part 155 and the second horizontal adhesive part 156 bonded to the first sheet 151 and the second sheet are included. It thus has a first sealing space 115 sealed between the first sheet and the third sheet and a second sealing space 116 between the second sheet and the third sheet. Even in this case, the opening 154 is sealed after the contents are inserted. The reason why the horizontal adhesive portion is formed to be layered is to allow the contents inserted into the first sealing space and the second sealing space to be opened separately without being opened at the same time. This packaging container is very useful when the contents are different or the same contents have different usage times.

Although the position of the 1st sheet and the 2nd sheet was specific in the figure, in fact, top and bottom are mutually interchangeable, and they can mutually change.

A packaging container having this pocket can be used by inserting a getter, a moisture absorbent, or the like necessary in the pocket, so that the material required for storage can be packed together according to the contents.

The waste container manufacturing method of the present invention comprises the steps of: aligning the first and second continuous sheets to be laminated up and down when pressed by a sealing press;

Inserting a continuous third sheet bonded between the first sheet and / or the second sheet when pressed by the sealing press, between the first and second sheets arranged vertically;

Sealing the laminated first, second, and third sheets in a “c” shape to bond the edges of the first sheet of the closed container made of a container and the third sheet overlapping the three edges of the second sheet to each other; It is made, including.
In this case, the width of the third sheet is equal to or smaller than the width of the first and second sheets.

In the method, the width of the third sheet may be 10% or more with respect to the widths of the first and second sheets, and the step 2-1 of forming a through hole in the first sheet by a punching process before performing step 3; And a step 2-2 of sealing the periphery of the through hole by thermally compressing the periphery of the through sheet of the first sheet and the corresponding portion of the third sheet.

In addition, the method includes sealing the first sheet or the second sheet and a portion of the third sheet so that the edge portion of the third sheet is sealed so as to form a pocket having an edge of the third sheet as an opening before performing step 3. Steps 2-3 are opened to form pockets to which the remaining three sides are bonded.

Prior to performing step 3, the receiving portion and the inserting portion of the sealing means exclusively have a receiving portion with a groove formed therein and an inserting portion having a rail inserted into the groove and elastically coupled to the first sheet and the third sheet. The method further includes attaching steps 2-4.

4 is a schematic partial cross-sectional view for explaining the apparatus used to implement the method of the present invention and to produce the containers of the present invention.

What can be made by the manufacturing method of the present invention are those usually called three-sided sealing rods, standing pouches, zipper bags, and the like.

These product packaging containers use the product's label, advertisement text, usage, trademark, etc. printed on the packaging surface. These seals typically seal two printed sheets on three sides to form an open envelope. The inlet is sealed after inserting the contents.

The packaging of the present invention is also required to use a plastic sheet printed with advertising stationery, trademarks, pictures, photos, etc. required.

First, the manufacturing process of the sealed packaging container (for example, kimchi packaging) with a pocket inside will be described.

The film is unrolled from the plastic film roll 41 to be continuously conveyed by the rollers. The film unrolled from the roll 41 is vertically moved by the guide rollers 61, 62, and 63, and is cut by the cutting knife 43 to be separated into the first sheet 1 and the second sheet 2. Proceed horizontally again. At this time, while the third sheet 3 is released from the separator roller 43, it is inserted between the first sheet 1 and the second sheet 2 and proceeds.

There are several drive rollers to tension the sheets for conveying, and several guide posts and rollers to guide the flow of the sheet. In the drawings, these are schematically shown, and reference numerals 61 to 79 are denoted. The rollers, guide rollers, and posts shown in the drawings are not necessarily shown and are shown for convenience of description. This is because, if a device such as a punch or a sealing press already has a guide post function, no additional guide post or roller is required.

The three sheets 1, 2, and 3 into which the third sheet is inserted are separated and spaced apart while the first sheet is guided by the second sheet and the third sheet and the rollers 68 and 76, and then the first sheet is moved. After (1) passes through the punches 44 and 45, the third sheet 3 is coalesced with the first sheet 1, and is first bonded to the pocket by the sealing presses 46 and 47 before proceeding. Subsequently, the first sheet and the second sheet are transversely sealed by the sealing presses 48 and 49 together with the third sheet in the middle, and again by the sealing presses 50 and 51 in the longitudinal direction, and the three sides After the adhesion, the adhesive portion is cut by the cutters 52 and 53 and separated into one single envelope.

The above description describes the separation and flow of sheets in the manufacture of pocket envelopes, and the flow of sheets can be different for other uses. That is, the three sheets 1, 2, and 3 in which the third sheet is inserted may allow the first sheet and the third sheet to pass through the punches 44 and 45 together, and the third sheet together with the second sheet. You can also make it flow.

In addition, a sealing press may be installed so that the punch 44 and 45 may be sealed in the horizontal direction at the same time as the punch. Thus, these sealing presses may be installed by moving forward or backward than the illustrated position, and a larger number of presses may be installed.

Next, the manufacturing process of the transparent window bag mainly used for grain packaging will be described.

In this process, the first sheet is transferred between the punches 44 and 45 while the through-hole for the transparent window is punched by the punches 44 and 45, and then the first and third sheets are merged (in this case, the third sheet is transparent. The sealing presses 46 and 47 seal around the through hole and then, as described above, to the sealing presses 48 and 49 together with the third sheet with the first and second sheets in the middle. By the transverse direction, again by the sealing presses (50, 51) in the longitudinal direction, the three sides are bonded and then the adhesive portion is cut by the cutters 52, 53 are separated into one single envelope .

In order to make a packaging container having two interior spaces of the present invention, the first, second, and third sheets stacked in sequence are immediately arranged without a punch or an intermediate sealing process. After sealing together in the transverse direction by the sealing presses (48, 49), and again in the longitudinal direction by the sealing presses (50, 51) are bonded to the three sides after the adhesive portion by the cutter (52, 53) It is cut and separated into one single envelope.

According to the present invention, the zipper bag has a zipper sealing means first attached to the first sheet and the third sheet by sealing and then transversely by the sealing presses 48 and 49 together with the third sheet in which the first sheet and the second sheet are centered. After sealing, the three sides are bonded by sealing again in the vertical direction by the sealing presses (50, 51) and then the adhesive portion is cut by the cutters 52, 53 are separated into one single envelope.

Although not shown in Figure 4, the supply means of the zipper, the roll is rolled around the zipper is installed in the ball with the roll roll, the receiving portion and the insert of the zipper may be inserted continuously between the first sheet and the third sheet.

 SUMMARY OF THE INVENTION An object of the present invention is to provide improved sealed containers and a method of manufacturing the same, in which the inconveniences of conventional sealed containers (having an envelope form) are solved.                     

The manufacturing process of the packaging container made of plastic sheet can be simplified and mechanized, thereby reducing the production cost.

Unsanitary packaging methods have been improved in a sanitary manner, and bags that can be separated and packaged separately can be conveniently used.

The transparent window bag can be used as a packaging container for packing grains such as rice, beans, jaws, kimchi, and the like, and can shorten the process of joining sheets compared to the conventional seals, thereby reducing production costs.

The packaging container with a zipper is convenient because it can be sealed again to some extent by closing the zipper even after opening the sealed package.

Packaging containers with pockets can be used by inserting the necessary getter, moisture absorbent, etc. in the pocket, it is convenient to be able to package the materials necessary for storage according to the contents.

In a container having two packaging spaces, the contents inserted into the first sealing space and the second sealing space can be opened and used separately without being opened at the same time, so that different contents may be packed or used for the same contents. This is very convenient when different from each other.
