Description

Safe guard zipper bag {SAFE GUARD ZIPPER BAG}

The present invention relates to a safe guard zipper bag, and more specifically, to a safe guard zipper bag that is difficult to open from the outside and can be opened by a simple operation.

In general, a zipper bag refers to a packaging bag equipped with a zipper consisting of male and female joints on the entrance side. Items are stored inside the bag and the zipper is closed to maintain airtightness and effectively protect the contents from the external environment. It is a supply.

It is very useful for storing food that requires freshness and cleanliness, or for storing liquid substances that are prone to leaking, and furthermore, a self-standing pouch or document bag (with a zipper that allows the opening to be opened and closed). flat bag) is known.

The zipper mounted on such a bag consists of a male track (male zipper) and a female track (female zipper) that can be joined together.

The male track and the female track are each formed to face each other on the inner surface of a pair of opposing face members of the bag main body and extend in the transverse direction of the bag main part. Since the zipper generally extends over the entire transverse area of the bag main body, by opening the zipper the bag main part is opened over the entire transverse area.

However, depending on the stored contents, there is a need to make it difficult to open from the outside, and there is a safety issue, especially if it contains items that should not be opened by children or infants.

Taking this into consideration, there are cases where double or triple zippers are used, but these are also structured so that they can be easily opened with a little bit of force. Recently, zipper bags with safety locks are being sold, but these are designed to increase stability and However, it has the problem of being inconvenient to use and increasing costs.

Republic of Korea Registered Utility Model Publication 20-0440413 discloses a double zipper bag, but it focuses on storage space efficiency rather than stability.

To solve this problem, the present applicant applied for a safe guard zipper bag in Korea Patent No. 10-2058080 and received patent registration.

However, the safe guard zipper bag registered in Korea Patent No. 10-2058080 is excellent in terms of efficiency, but needs to be improved to a simpler structure.

The term vinyl used in the present invention is not a scientific name, but is a generic term for films made of synthetic resins that are generally used in the market, and includes not only vinyl resins with a vinyl group, but also plastic bags and greenhouses used on the market even without a vinyl group. It can be used as a general term for vinyl for vinyl zipper bags made from synthetic resin film products such as polyethylene film products, which are transparent and transmit sunlight, similar to the vinyl used in vinyl products.

The safe guard zipper bag 10 according to the present invention may have a zipper 17 formed of male and female coupling members 20 and 30 that engage with each other on the upper side of the synthetic resin body.

The zipper bag 10 can be sealed by heat-sealing the peripheral portion 11 including the left portion 11a, right portion 11b, lower portion 11c, and upper portion 11d in all directions.

A zipper 17 having male and female coupling members 20 and 30 is formed on the lower side of the upper sealing part 11d of the peripheral part 11 sealed on all sides, and the upper sealing part 11d of the peripheral part 11 is formed. An opening portion 12 for cutting and opening may be provided between the zipper bags 17 to prevent foreign substances from penetrating into the inside of the zipper bag 10.

In addition, a V-shaped cutout groove 13 may be formed on one side of the opening portion 12 of the zipper bag 10, and an opening instruction line 14 is printed horizontally from the cutout groove 13, so that the zipper bag 10 is opened in the cutout groove 13. It may be configured to be opened by applying force.

Among the peripheral portions 11 sealed on all sides of the zipper bag 10, the upper sealing portion 11d may be formed to have a larger width than the left, right, and lower sealing portions 11a, 11b, and 11c, and the middle portion may be used to sell products. It can be hung on a hook provided on a poetry display stand, etc., or a hanging hole 15 can be formed for a handle.

An opening member 16 may be formed on one side of the zipper 20 to facilitate opening the zipper 20.

In general, the zipper of a plastic zipper bag is easy to open in the opening direction (upward direction of the zipper 20 in the drawing), and is not easy to open in the inner direction containing the contents (opposite the opening direction relative to the zipper 20). is formed

For this purpose, the shapes of the male and female zippers are different.

That is, the female coupling member of the zipper is formed with a pair of locking portions, of which the inner hook portion is bent toward the hook portion of the male coupling member, and the catching portion in the opening direction is directed away from the hook portion of the male coupling member. It can be configured to form an inclined surface.

However, in the present invention, the direction of the male and female coupling members of a typical zipper is set in the opposite direction so that the zipper cannot be easily opened in the opening direction, thereby preventing children from easily opening it.

However, since the zipper bag is not easily opened by holding both sides of the zipper bag and pulling it to both sides in the opening direction for opening, an opening member 16 is further configured as an auxiliary means for opening.

In order to open the zipper, the user can separate the zipper 17 into both sides while pushing a finger or tool into the opening member 16 formed on one side of the zipper 17.

The opening member 16 is a part that loses its function as a zipper by applying a predetermined pressure to the female coupling member or/and the male coupling member, and is located inside the opening part 12 of the zipper bag 10 so that children can easily find it. Therefore, it may become virtually difficult to release the zipper bag 10 of the present invention using only the zipper 17.

The structure of the zipper 17 will be explained again with reference to FIGS. 2 to 4 below, and the structure of the opening member 16 will be explained again with reference to FIG. 5.

FIG. 2 is a first example diagram of the cross-sectional structure of portion A of FIG. 1.

Referring to FIG. 2, the zipper 17 according to an embodiment of the present invention is formed in the shape of a strip extending long in one direction and is used to open and close the zipper bag 10.

The zipper 17 includes a male coupling member 20 and a female coupling member 30.

The upper direction in the drawing is the outer direction to open the zipper, and the lower direction is the inner direction where the contents are contained.

The male coupling member 20 includes a first support portion 21, a protrusion 22, and a head portion 23.

The first support portion 21 has a strip shape extending in one direction, is attached to the inside of the zipper bag 10, and supports the protrusion 22.

The protrusion 22 protrudes in a vertical direction from the first support part 21 and extends in one direction like the first support part 21.

The ends of the protrusion are expanded to both sides to form the head portion 23.

The head portion 23 is an element that is inserted into the female coupling member 30 and couples the male coupling member 20 and the female coupling member 30 to each other, and includes a first engaging portion 24 and a second protruding portion at both ends, respectively. Includes a hanging portion (25).

The arm coupling member 30 includes a second support portion 31, a first side wall 32, and a second side wall 33.

The second support part 31 has a strip shape extending in parallel in the same direction as the first support part 21, is attached to the inside of the zipper bag 10, and supports the first side wall 32 and the second side wall 33.

The first side wall 32 and the second side wall 33 protrude from the second support portion 31, extend side by side in the same direction as the second support portion 31, and have a head portion 23 of the male coupling member 10 at the center. ) forms a receiving groove 36 in which the .

The end portions of the first side wall 32 and the second side wall 33 are respectively bent into the receiving groove 36 to form the first hook portion 34 and the second hook portion 35.

The first hook portion 34 and the second hook portion 35 press the protrusion 22 on both sides of the protrusion 22, respectively, thereby sealing the male coupling member 20 and the female coupling member 30.

Here, the purpose of the present invention is to provide a SAFE GUARD zipper bag that prevents children from easily opening the zipper by constructing the zipper 17 so that it cannot be easily opened in the opening direction.

The first hook portion 34 and the second hook portion 35 are respectively hooked to the first locking portion 24 and the second locking portion 25 of the head portion 23 to form a male coupling member 20 and a female coupling member. Combine (30).

At this time, the first locking portion 24 of the male coupling member 20 protrudes toward the first side wall 32 and is bent toward the first hook portion 34.

On the other hand, the second catching portion 25 protrudes toward the second side wall 33 and forms an inclined surface in a direction away from the second hook portion 35.

Additionally, the second locking portion 25 may be formed to be smaller than the width of the first locking portion 24 in order to weaken the coupling force.

Accordingly, the first hook portion 34 and the second hook portion 35 are formed symmetrically to each other, but the first hook portion 24 and the second hook portion 25 are formed in an asymmetric shape to form the zipper bag 10. It is formed in a structure that strengthens the bonding force in the opening direction, and is configured so that it can be opened using the opening member 16 when opening.

FIG. 3 is a second exemplary view of the cross-sectional structure of portion A of FIG. 1, and FIG. 4 is a third exemplary view of the cross-sectional structure of portion A of FIG. 1.

3 and 4 have the same configuration as that of FIG. 2, except that the shapes of the second locking portions 25, 25a, and 25b are different from those of FIG. 2.

In the case of Figure 2, the second locking portion 25 protrudes toward the second side wall 33 and has an inclined surface formed in a direction away from the second hook portion 35.

On the other hand, in the case of FIG. 3, the second hook portion 25a protrudes toward the second side wall 33 and is formed so that the surface on which the second hook portion 35 is hooked is a vertical plane, thereby increasing the coupling force in the inner direction. It is a more strengthened structure.

In addition, in the case of FIG. 4, the second locking portion 25b has the same shape as the first locking portion 24, protrudes toward the second side wall 33, and is bent toward the second hook portion 35. It is a structure that further strengthens the bonding force in the direction.

FIG. 5 is a first example view of the cross-sectional structure of part B of FIG. 1, and FIG. 6 is a second example view of the cross-sectional structure of part B of FIG. 1.

Figures 5 and 6 are diagrams showing the configuration of the opening member 16.

The position of the opening member 16 may be located on either side of the zipper 17, but is preferably located on either side of the zipper 17, and its length is preferably set to approximately 10 mm.

Referring to FIGS. 5 and 6 , the opening member 16 may refer to a member in which the coupling force of the male and female coupling members 20 and 30 has been lost.

It is basic for the male and female coupling members 20 and 30 to maintain coupling strength, but in the present invention, the coupling strength is lost for a certain length of the zipper 17 and that part is used to open the zipper 17.

That is, the zipper 17 of the present invention is different from a typical zipper in terms of the coupling force in the opening direction and the inner direction, so that it cannot be easily opened by strengthening the coupling force in the opening direction, but instead, the zipper 17 can be opened through the opening member 16 that has lost the coupling force. The significance is to provide a safety guard zipper bag that prevents children or infants from easily opening the zipper bag.

Referring to FIG. 5, the first and second hook parts 34 and 35 are pressed to lose the coupling force of the arm coupling member 30 of the opening member 16, thereby connecting the first and second hook parts 34 and 35 of the head part 23. The coupling force may be lost by preventing it from being caught in the locking portions 24 and 25.

Referring to FIG. 6, it can be implemented in a shape in which the first and second locking portions 24 and 25 of the head portion 23 are removed so as to lose the coupling force of the male engaging member 20 of the opening member 16.

In addition, as shown in FIGS. 5 and 6, the male coupling member 20 is formed as shown in FIG. 6, and the female coupling member 30 is formed as shown in FIG. 5, so that the coupling force of both the male and female coupling members 20 and 30 is lost. Of course, configuration is also possible.

With this shape and structure, it is generally difficult to open the outer opening, which especially prevents children and infants from easily opening the zipper bag, making it safe for plastic zipper bags such as detergents where children or infants should not come into contact with the contents. It can be useful for guarding.

Although the present invention as described in detail above has been described based on limited embodiments and drawings, the present invention is not limited thereto, and the present invention can be described by those skilled in the art to which the present invention pertains. Various modifications and variations are possible within the scope of equivalence of the spirit and scope of the patent claims.

However, it is clear that such simple modifications and variations cannot fall outside the scope of the present invention.
