Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a zipper bag,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a zippered bag and a method of manufacturing the same, and more particularly, to a zippered bag including a moisture absorbing member on the inner side and a method of manufacturing the same.

Generally, the zipper bag refers to a multipurpose storage case provided with a zipper type coupling unit in which male and female forms are paired on an open inlet side. Accordingly, by housing various objects on the inner side and locking the engaging portions, the inner object can be effectively sealed from the outside. In particular, such a zipper bag is used for storage of food or the like requiring freshness or cleanliness and for storing liquids.

On the other hand, foods such as meat, fish, vegetables, fruits and the like, when the cells are destroyed, may cause the fluidity of the inside and the outside of the cells to flow out and degrade the freshness of the food. When the freshness of the food is lowered, the water holding capacity of the food is lowered, so that more liquid flows out of the food, thereby accelerating the self-decomposition of the food, bacterial growth and discoloration. Especially, vegetables or fruits are often stored in the storage box due to the moisture that is present inside or stored in an unsanitary manner.

In order to solve such a problem, a method of keeping food in a zipper bag by wrapping a food with a newspaper or kitchen towel at home is used. However, in such a case, there is a problem that the contents can not be confirmed from the outside, so that the state or kind of food can not be confirmed. In addition, since the food is stored using a separate moisture absorbing member such as a newspaper, there is a problem that the volume is large during storage and the user is troublesome.

On the other hand, in the conventional method of manufacturing a zipper bag, two vinyl fabrics are overlapped and pressed or an open side where no zipper is formed is bonded using an adhesive. However, in such a manufacturing method, there is a problem that, when the positions of the upper and lower vinyl fabrics do not coincide precisely, defects may occur or a separate cutting process must be additionally performed to meet the unit specifications of the zipper bag.

Accordingly, there is a need for a new type of zippered bag and a method for manufacturing the same, in order to solve such conventional problems.

More specifically, the present invention relates to a zipper bag including a moisture absorbing member on the inner side and including at least one hole in the moisture absorbing member, and a method of manufacturing the same.

The technical problems of the present invention are not limited to the above-mentioned technical problems, and other technical problems which are not mentioned can be understood by those skilled in the art from the following description.

In order to achieve the above object, a method of manufacturing a zipper bag is provided. The method of fabricating a zipper bag includes: laminating a hygroscopic fabric to at least one region of a vinyl fabric; Forming female fasteners and male fasteners on both sides of each of said at least one region on said vinyl fabric; Folding the vinyl fabric so that the female zipper and the resin fastener corresponding to each other are coupled to each other; Cutting the spaced portion between the at least one region of the vinyl fabric; And adhering both open sides of the cut vinyl fabric.

Preferably, the at least one region includes a first region and a second region that are spaced apart from each other, and the folding step includes a step of folding the first region and the second region on both sides of the first region and the second region, And by folding the first region and the second region in opposite inward directions so that the female zipper and the resin fastener formed are mutually coupled.

In addition, preferably, the hygroscopic material may include at least one of pulp and nonwoven fabric.

Preferably, a plurality of holes may be formed in the hygroscopic raw fabric.

In addition, preferably, a guide line for guiding the cutting position may be formed at the spacing between the at least one area.

To achieve the above object, a zipper bag is provided. The zippered bag is made of a transparent or semitransparent vinyl material and has one end opened to receive an object therein; A moisture absorbing part formed integrally with at least one area of the inner surface of the body part and made of a hygroscopic material; And a zipper formed on an inner surface of one end of the main body so that one end of the main body is detachable.

Preferably, the hygroscopic material may include at least one of pulp and nonwoven fabric.

Preferably, the moisture absorbing portion may be formed with a plurality of holes through which the content housed inside can be confirmed.

According to the present invention, it is possible to increase the freshness of the food and increase the storage period by absorbing the moisture of the contents by forming the moisture absorption part inside the body part.

Further, according to the present invention, it is possible to confirm the content housed inside by forming a hole through the moisture absorption portion.

In addition, according to the present invention, it is not necessary to form a body portion and a moisture absorbing portion integrally with each other and to provide a separate moisture absorbing member, thereby enhancing convenience for the user.

Further, according to the present invention, by producing a plurality of zipper bags simultaneously through a series of processes such as folding and cutting, the manufacturing process of the zippered bag can be simplified, and the manufacturing time and manufacturing cost can be shortened.

1 and 2, the zippered bag 100 may include a main body 110, a moisture absorbing portion 120, and a zipper 130.

The upper portion of the main body 110 is opened to accommodate the objects therein. The main body 110 is preferably made of a transparent or translucent vinyl material in at least one region. That is, for example, at least one region of the main body 110 is formed of a transparent or semitransparent plastic such as polyethylene terephthalate (PET), polypropylene (PP), polyvinyl acetate (PVA) Or a combination of two or more thereof. Accordingly, the user can recognize the type, state, and the like of the content received therein.

The moisture absorbing part 120 may be formed on at least one area of the inner surface of the main body 110 and preferably smaller than the width of the main body 110. The moisture absorbing portion 120 may be made of a hygroscopic material. Accordingly, the moisture contained in the inside of the main body 110 can be absorbed. For example, the moisture absorbing portion 120 may be composed of at least one of a nonwoven fabric and a pulp member, but is not limited thereto. In one embodiment, the moisture absorption portion 120 may be integrally formed on the inner surface of the body portion 110. Accordingly, by merely inserting an object into the main body 110, food or the like can be stored for a long period of time, thereby enhancing convenience for the user. However, according to the embodiment, the moisture absorbing part 120 may be detachably mounted on the inner surface of the body part 110. [

The zipper 130 may be formed on the inner surface of one end of the main body 110 so that one end (i.e., an upper portion) of the opened main body 110 is detachable. The zipper 130 is preferably spaced apart from the open mouth of the main body 110 by a predetermined distance so that the user can easily fasten the zipper 130. For example, the zipper 130 may include a zipper 132 formed to have a protrusion on the inner surface of the main body 110, and an arm zipper 132 formed on the inner surface of the zipper 130 opposite to the zipper 130, (134). That is, the inner side of the main body 110 can be sealed through fastening of the male and female fasteners 132 and 134. At least one zipper 130 may be formed in accordance with an embodiment of the present invention. However, the zipper 130 may be variously modified in accordance with an embodiment of the present invention.

Figure 3 shows a zipper back according to an embodiment of the invention.

1 to 3 are referred to by the same terminology and reference numerals, and the description of FIGS. 1 and 2 described above is referred to in order to avoid repetition. Only differences between the embodiments will be described below.

Referring to FIG. 3, the zippered bag 300 may include a plurality of holes 310 in the moisture absorption portion 120.

That is, the plurality of holes 310 may be formed in the moisture absorbing portion 120 formed inside the main body 110. It is considered that the moisture absorbing part 120 is made of an opaque material such as a nonwoven fabric or a pulp material. Through this hole 310, the user can recognize the contents housed inside the main body part 110, And the state can be confirmed, so that the convenience of the user can be improved.

However, the structure of the moisture absorbing part 120 is merely an example, and the moisture absorbing part 120 according to the embodiment of the present invention can be variously modified and applied.

4 illustrates a method of manufacturing a zipper bag according to an embodiment of the present invention.

In step S410, a hygroscopic material may be laminated on at least one area of the vinyl fabric made of a transparent or semi-transparent material. For example, as described below with reference to FIGS. 5A-5C, at least one region of the vinyl fabric includes a first region and a second region, wherein the first region and the second region each comprise a web of hygroscopic material . The width of the composite region formed on the vinyl fabric may preferably be smaller than the width of the vinyl fabric. The step S410 may be performed through various methods such as adhesion using an adhesive, ultrasonic welding, and thermal welding. For example, a synthetic resin (for example, polyethylene (PE), which can be melted by heat) is applied to one surface of a hygroscopic raw fabric, one surface of the applied hygroscopic raw fabric is superimposed on a vinyl fabric, The vinyl fabric and the hygroscopic fabric can be thermally fused to each other by applying a predetermined heat to the fabric.

Meanwhile, the hygroscopic material has a property of absorbing the surrounding water, and may preferably include at least one of pulp and nonwoven fabric. As a result, the zipper bag absorbs the moisture discharged from the contents of the food or the like stored therein, so that the contents can be kept fresh for a long period of time. In one embodiment, the hygroscopic fabric may be formed with a plurality of holes therethrough. This takes into consideration that the hygroscopic material is made of an opaque material, and by forming a plurality of holes in the hygroscopic material, the user can recognize the contents housed inside the zipper bag.

In step S420, the zipper can be formed on both sides of each of at least one area where the hygroscopic material of the vinyl fabric is laminated. The zipper may preferably include a zipper 132 and an arm zipper 134. For example, the handle fastener 132 and the arm fastener 134 may be alternately formed along the length direction of the vinyl fabric. In one embodiment, step S420 may be performed by attaching a zipper tape, on which a hand paper fastener 132 and an arm fastener 134 are formed, to a vinyl fabric. Alternatively, in one embodiment, step S420 may be a method of directly pressing the resin fastener 132 and the arm fastener 134 onto a vinyl fabric through a mold provided with a shape of a handle fastener 132 and an arm fastener 134 Lt; / RTI > However, this method is illustrative, and step S420 may be performed by various methods according to an embodiment to which the present invention is applied.

In step S430, the vinyl fabric may be folded so that the male and female fasteners 132 and 134, which correspond to each of at least one region of the vinyl fabric, are mutually bonded. For example, as described below with reference to FIGS. 5A to 5C, in the case where two regions in which hygroscopic webs are laminated on a vinyl fabric are formed so as to be spaced apart from each other, each region may be folded in the inward facing direction have. On the other hand, at least one area of the vinyl fabric and the hygroscopic fabric is preferably provided with a woven wire so that folding can be facilitated.

In step S440, the folded vinyl fabric part can be separated by cutting the spaced-apart part between at least one area where the hygroscopic fabric is lapped. Thereby, the vinyl fabric is cut so as to have a predetermined unit size in the folded state (i.e., the state in which the corresponding female and male fasteners 132, 134 are engaged), so that one or more zipper bags can be manufactured simultaneously . In particular, the step S440 of cutting the vinyl fabrics after the step of folding the vinyl fabric (S430) is performed so that the length of the fabric, the arms and the fasteners 132, 134, which form both sides of the zipper bag, So that it is possible to more easily perform the step of bonding the open sides of the vinyl fabric performed in step S450. Accordingly, the process of manufacturing the zippered bag can be further simplified, and the rate of defective products can be reduced. Meanwhile, in one embodiment, at least one guideline 550 guiding the cutting position between the regions may be formed at the spaced-apart regions between the regions where hygroscopic webs are joined.

In step S450, both open sides of the cut vinyl fabric may be bonded. For example, the step S450 may be performed through heat fusion, high frequency fusion, or the like. In addition, the adhesive may be applied to at least one of the inside and the outside of the vinyl fabric by applying an adhesive material. However, the present invention is not limited thereto. According to an embodiment to which the present invention is applied, Can be used.

The order and manner of performing at least one step of the zipper bag manufacturing method 400 may be variously modified according to the embodiment to which the present invention is applied. For example, although it is shown in FIG. 4 that step S450 is performed after step S440, according to an embodiment, step S450 may be performed first to bond both open sides first after folding, .

Figs. 5A, 5B and 5C illustrate examples of the process of the zipper-bag manufacturing method of Fig.

Referring to FIG. 5A, the hygroscopic material 520 may be joined to the first and second regions 512 and 514 of the vinyl fabric 510, respectively. The first region 512 and the second region 514 may preferably be formed continuously in the longitudinal direction of the vinyl fabric 510. Then, the resin fastener 532 and the arm fastener 534 can be formed on both sides of the first region 512 and the second region 514, respectively.

5B, the vinyl fabric 510 is folded so that the resin fastener 532 and the arm fastener 534 formed on both sides of the first area 512 and the second area 514 are engaged with each other . Specifically, as shown in FIG. 5B, the first area 512 and the second area 514 of the vinyl fabric 510 can be folded inward toward each other. At this time, the center region of each of the first region 512 and the second region 514 may be provided with a connecting wire 540 for facilitating the folding.

Next, referring to FIG. 5C, it is possible to cut the spaced portion (i.e., the center portion of the spacing region) between the folded first region 512 and the second region 514. For example, at least one guide line 550 may be formed at a distance between the first area 512 and the second area 514 to guide the cutting position. Thus, the vinyl fabric 510 is cut into unit lengths so as to include the lint region, the arm and the resin fasteners 532 and 534, respectively.

The open both sides of each of the separated first region 512 and second region 514 can then be bonded. Accordingly, the two zipper bags can be simultaneously produced through one manufacturing process. However, the method of manufacturing such a zipper bag may be variously modified and applied according to the embodiment to which the present invention is applied, as one embodiment.

As described above, an optimal embodiment has been disclosed in the drawings and specification.
