Description

Technical Field

[0001] The present invention relates to a safety guard zipper bag, and more particularly to a safety guard zipper bag that is difficult to open from the outside and can be opened by a simple operation.

Background Art

[0002] Generally, a zipper bag refers to a packaging bag provided with a zipper composed of male and female coupling parts on the entrance side. By storing articles inside and closing the zipper, confidentiality can be maintained and the contents can be effectively protected from the external environment. It is a daily necessity.

[0003] It is very useful for storing foods and drinks that require freshness and cleanliness, and for storing liquid substances that are prone to leakage. Furthermore, a self-standable pouch or a flat bag provided with a zipper that can open and close the opening is known.

[0004] The zipper attached to such a bag is composed of a male track (male zipper) and a female track (female zipper) that can be coupled together.

[0005] The male track and the female track face each other on the inner surfaces of a pair of opposing flat portions (face members) of the bag body, and are respectively formed so as to extend in the lateral direction of the bag body. Since the zipper extends generally over the entire lateral direction of the bag body, by opening the zipper, the bag body is opened over the entire lateral region.

[0006] However, it is necessary to make it difficult to open from the outside depending on the contents to be stored. In particular, when the bag contains items that children or infants should not open, there is a safety problem.

[0007] Considering such points, there are cases where the zipper is doubled or tripled, but with a slight force applied, this is also a structure that can only be easily opened. Recently, zipper bags with a safety lock device added have been traded, but this has the problem of being inconvenient to use and costly, although it has enhanced stability.

[0008] Korean Registered Utility Model Publication No. 20-0440413 discloses a double zipper bag, but this focuses on the efficiency of the storage space rather than stability.

[0009] To solve such problems, the applicant of the present application has applied for a safety guard zipper bag in Korean Registered Patent No. 10-2058080 and has received a patent registration.

[0010] However, the safety guard zipper bag of Korean Registered Patent No. 10-2058080 is excellent in terms of efficiency, but needs to be improved as a simpler structure.

Summary of the Invention

Problems to be Solved by the Invention

[0012] The problem of the present invention for solving the above-mentioned conventional problems is to provide a zipper bag that is difficult to open easily.

[0013] In particular, it is to provide a zipper bag that is difficult for infants and children to open so that the contents cannot be taken out randomly.

[0014] Another object of the present invention is to provide a low-cost and high-efficiency safety zipper bag that can be produced with a simple structure without increasing the production method and unit production cost of the plastic zipper bag.

[0015] The problems to be solved by the present invention are not limited to the problems mentioned above, and other problems not mentioned will be clearly understood by those having ordinary knowledge in the technical field to which the present invention pertains from the following description.

Means for Solving the Problems

[0016] The safety guard zipper bag according to the present invention for solving the above problems is formed with a zipper for opening and closing composed of male and female coupling members. The male coupling member includes a strip-shaped first support portion extending in one direction, a protruding portion protruding vertically from the first support portion, and a head portion including first and second locking portions extending from the tip of the protruding portion to both sides. The female coupling member includes a strip-shaped second support portion extending in one direction, first and second side walls protruding from both sides of the second support portion, and first and second hook portions refracted inward from the first and second side walls, respectively. The first locking portion of the male coupling member is located in the opening direction in the upper side direction of the zipper, the first locking portion protrudes toward the first side wall, and is refracted toward the first hook portion. The second locking portion of the male coupling member is located in the inner direction in the lower side direction of the zipper, the second locking portion protrudes toward the second side wall, and an opening member in a form in which the coupling force of the male and female coupling members is lost may be formed on one side of the zipper.

[0017] Here, an inclined surface may be formed on the second locking portion in a direction away from the second hook portion.

[0018] Here, the second locking portion may protrude toward the second side wall and be formed such that the surface where the second hook portion is hooked is a vertical surface.

[0019] Here, the second locking portion may protrude toward the second side wall and be formed in a shape refracted toward the second hook portion.

[0020] Here, the opening member is such that the first and second hook portions of the female coupling member extend further to both sides than the widths of the first and second locking portions, causing the coupling force of the male-female coupling members to be lost, and allowing a finger or a tool to be inserted during opening to open the zipper.

[0021] Here, the opening member removes the first and second locking portions of the male coupling member so that they do not lock to the first and second hook portions, causing the coupling force of the male-female coupling members to be lost, and allowing a finger or a tool to be inserted during opening to open the zipper.

Advantages of the Invention

[0022] According to the configuration of the present invention described above, in particular, it is possible to provide a zipper bag that is difficult for infants and children to open, preventing the contents from being taken out randomly.

[0023] Also, it is possible to provide a low-cost, high-efficiency, safe zipper bag that can be produced with a simple structure without increasing the production method or production unit price of the plastic zipper bag.

[0024] However, the effects of the present invention are not limited to the above effects, and will be variously extended within the scope not departing from the spirit and scope of the present invention.

Mode for Carrying Out the Invention

[0031] Hereinafter, with reference to the accompanying drawings, the structure, operation, and effects of the safety guard zipper bag according to the present invention will be examined in detail.

[0032] The detailed description of the specific embodiments shown in the accompanying drawings is to be read in connection with the accompanying drawings, which are considered to be a part of the overall description of the invention. References to directions and orientations are for convenience of description only and are not intended to limit the scope of the invention in any way.

[0033] Specifically, terms indicating positions such as "lower, upper, horizontal, vertical, upper side, lower side, upward, downward, upper part, lower part", and derivatives thereof (e.g., "horizontally, downwardly, upwardly") must be understood with reference to all of the drawings and related descriptions being explained. In particular, such relative terms are for convenience of description only and do not require that the device of the present invention be configured or operate in a specific direction.

[0034] Also, terms indicating the mutual coupling relationship between components such as "mounted, attached, connected, joined, mutually connected" mean that individual components are directly or indirectly attached or connected or fixed, unless otherwise stated, and this should be understood as a term including not only a state of being movably attached, connected, or fixed, but also a state of being immovable.

[0035] When adding reference signs to the components of each drawing, it should be noted that for the same component, even if it is shown on other drawings, it should preferably have the same sign. Also, when explaining the present invention, if it is determined that a specific explanation of a related publicly known configuration or function may obscure the gist of the present invention, the detailed explanation thereof is omitted.

[0036] Figure 1 is a perspective view of a safety guard zipper bag according to the present invention.

[0037] As the material for the zipper bag, vinyl paper can generally be used, and for the vinyl paper to form a somewhat voluminous zipper at the opening of the bag, a somewhat thick and durable material can be used.

[0038] The term "vinyl" used in the present invention is not an academic term, and in the sense of generally referring to a film made of a synthetic resin that is commonly used in the market, it refers not only to a vinyl resin having a vinyl group but also, in the same sense as the vinyl of vinyl products such as vinyl bags and vinyl greenhouses that are used in the market without having a vinyl group, to vinyl for a vinyl zipper bag made of a synthetic resin film product such as a polyethylene film product that is transparent and has the property of transmitting sunlight.

[0039] A safety guard zipper bag 10 according to the present invention may have a zipper 17 formed by male and female coupling members 20 and 30 that mesh with each other on the upper side of a synthetic resin material body.

[0040] The zipper bag 10 may have a peripheral edge 11 including a left side 11a, a right side 11b, a lower side 11c, and an upper side 11d heat-sealed on all four sides to be sealed.

[0041] A zipper 17 having male and female coupling members 20 and 30 is formed below the upper sealing portion 11d of the peripheral portion 11 with four sides sealed. An opening portion 12 for cutting and opening is provided between the upper sealing portion 11d of the peripheral portion 11 and the zipper 17, and it may be configured to prevent foreign matter from penetrating into the inside of the zipper bag 10.

[0042] Also, a V-shaped notch groove 13 may be formed on one side of the opening portion 12 of the zipper bag 10, and a horizontal opening instruction line 14 may be printed from the notch groove 13, and it may be configured to be able to apply force to the notch groove 13 to open it when opening.

[0043] Among the peripheral portions 11 with four sides of the zipper bag 10 sealed, 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. A hook provided on a display stand or the like at the time of product sales may be hung on the middle portion, or a hand hole 15 may be formed for hand-held use.

[0044] An opening member 16 for facilitating the opening of the zipper 20 may be formed on one side portion of the zipper 20.

[0045] Generally, the zipper of a plastic zipper bag is formed such that it is easy to open in the opening direction (the upward direction of the zipper 20 in the drawing), and it is not easy to open in the inner direction (the opposite side of the opening direction with respect to the zipper 20) where the contents are placed.

[0046] For this reason, the male and female shapes of the zipper are made different.

[0047] That is, a pair of locking portions are formed on the female coupling member of the zipper. Among them, the locking portion in the inner direction has a shape refracted toward the hook portion of the male coupling member, and the locking portion in the opening direction may be configured such that an inclined surface is formed in a direction away from the hook portion of the male coupling member.

[0048] However, in the present invention, the directions of the male and female coupling members of a general zipper are set in opposite directions so that the zipper is configured not to be easily opened in the opening direction, and children are prevented from easily opening it.

[0049] Simply grasping both sides of the zipper bag in the opening direction and pulling while grasping both sides will not easily open the zipper bag. Therefore, an opening member 16 is further configured as an auxiliary means for opening.

[0050] In order for the user to open the zipper, it is possible to separate the zipper 17 to both sides while pressing a finger or a tool into the opening member 16 formed on one side of the zipper 17.

[0051] The opening member 16 is a part that applies a predetermined pressure to the female coupling member or (and) the male coupling member to cause the loss of the function as a zipper, and is located inside the opening portion 12 of the zipper bag 10 so that children cannot easily find it. Therefore, it can be practically difficult to release the zipper bag 10 of the present invention with only the zipper 17.

[0052] The structure of the zipper 17 will be described again with reference to FIGS. 2 to 4 below, and the structure of the opening member 16 will be described again with reference to FIG. 5.

[0053] FIG. 2 is a first exemplary view of the cross-sectional structure of part A in FIG. 1.

[0054] Referring to FIG. 2, the zipper 17 according to an embodiment of the present invention is formed in a strip shape that extends long in one direction and is used for opening and closing the zipper bag 10.

[0055] The zipper 17 includes a male coupling member 20 and a female coupling member 30.

[0056] The upper direction in the drawing is the outer side and the direction for opening the zipper, and the lower direction is the inner side direction where the contents are located.

[0057] The male coupling member 20 includes a first support portion 21, a protruding portion 22, and a head portion 23.

[0058] The first support portion 21 is in the shape of a strip extending in one direction and is attached inside the zipper bag 10 to support the protruding portion 22.

[0059] The protruding portion 22 protrudes vertically from the first support portion 21 and extends in one direction together with the first support portion 21.

[0060] The ends of the protruding portion are expanded on both sides to form the head portion 23.

[0061] The head portion 23 is inserted into the female coupling member 30 and includes a first locking portion 24 and a second locking portion 25 protruding from both ends respectively, serving as an element to couple the male coupling member 20 and the female coupling member 30 to each other.

[0062] The female coupling member 30 includes a second support portion 31, a first side wall 32, and a second side wall 33.

[0063] The second support portion 31 is in the shape of a strip extending side by side in the same direction as the first support portion 21 and is attached inside the zipper bag 10 to support the first side wall 32 and the second side wall 33.

[0064] 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 form a receiving groove 36 in the center for receiving the head portion 23 of the male coupling member 10.

[0065] The ends of the first side wall 32 and the second side wall 33 are respectively refracted inside the receiving groove 36 to form a first hook portion 34 and a second hook portion 35.

[0066] The first hook portion 34 and the second hook portion 35 respectively press the protruding portion 22 from both sides of the protruding portion 22 to seal the male coupling member 20 and the female coupling member 30.

[0067] Here, the present invention aims to provide a SAFE GUARD zipper bag in which children cannot easily open the zipper by configuring the zipper 17 not to be easily opened in the opening direction.

[0068] The first hook portion 34 and the second hook portion 35 are respectively hooked on the first locking portion 24 and the second locking portion 25 of the head portion 23 to couple the male coupling member 20 and the female coupling member 30.

[0069] At this time, the first locking portion 24 of the male coupling member 20 protrudes toward the first side wall 32 and is refracted toward the first hook portion 34.

[0070] On the contrary, the second locking portion 25 protrudes toward the second side wall 33, and an inclined surface is formed in a direction away from the second hook portion 35.

[0071] Further, the second locking portion 25 can be formed to be even smaller than the width of the first locking portion 24 in order to weaken the coupling force.

[0072] Therefore, although the first hook portion 34 and the second hook portion 35 are formed symmetrically with respect to each other, the first locking portion 24 and the second locking portion 25 are formed in an asymmetric shape, and the coupling force in the opening direction of the zipper bag 10 is formed in a structure that is strengthened so that it can be opened using the opening member 16 during opening.

[0073] FIG. 3 is a second exemplary view of the cross-sectional structure of part A in FIG. 1, and FIG. 4 is a third exemplary view of the cross-sectional structure of part A in FIG. 1.

[0074] Comparing FIGS. 3 and 4 with FIG. 2, the remaining configurations are the same as those in FIG. 2 except that the shapes of the second locking portions 25, 25a, and 25b are different.

[0075] In the case of FIG. 2, the second locking portion 25 protrudes toward the second side wall 33, and an inclined surface is formed in a direction away from the second hook portion 35.

[0076] On the reverse side, in the case of FIG. 3, the second locking portion 25a protrudes toward the second side wall 33 and is formed such that the surface where the second hook portion 35 is hooked is a vertical surface, which is a structure that further strengthens the coupling force in the inner direction.

[0077] Also, in the case of FIG. 4, the second locking portion 25b has the same shape as the first locking portion 24 and protrudes toward the second side wall 33 and is refracted toward the second hook portion 35, which is a structure that further strengthens the coupling force in the inner direction.

[0078] FIG. 5 is a first exemplary view of the cross-sectional structure of part B in FIG. 1, and FIG. 6 is a second exemplary view of the cross-sectional structure of part B in FIG. 1.

[0079] FIGS. 5 and 6 are drawings showing the configuration of the opening member 16.

[0080] The position of the opening member 16 can be anywhere on one side of the zipper 17, but preferably it is located at a position on either of the two side surfaces, and its length is preferably set to a length of about 10 mm.

[0081] Referring to FIGS. 5 and 6, the opening member 16 may mean a member in which the coupling force of the male-female coupling members 20, 30 is lost.

[0082] The male-female coupling members 20, 30 are basically required to maintain the coupling force. However, in the present invention, the coupling force is lost only for a certain length of the zipper 17, and that part is used to open the zipper 17.

[0083] That is, the zipper 17 of the present invention is different from a general zipper in the coupling force in the opening direction and the inner direction. Instead of strengthening the coupling force in the opening direction and making it difficult to open, the zipper 17 can be opened through the opening member 16 in which the coupling force is lost, so as to provide a safety guard zipper bag that prevents children and infants from easily opening the zipper bag.

[0084] Referring to FIG. 5, the coupling force of the female coupling member 30 of the opening member 16 can be lost by pressing the first and second hook portions 34, 35 so that they are not caught by the first and second locking portions 24, 25 of the head portion 23, thereby losing the coupling force.

[0085] Referring to FIG. 6, it is possible to embody the shape in which the first and second locking portions 24, 25 of the head portion 23 are removed so as to lose the coupling force of the male coupling member 20 of the opening member 16.

[0086] Also, as shown in FIGS. 5 and 6, it is of course possible to form the male coupling member 20 as shown in FIG. 6 and the female coupling member 30 as shown in FIG. 5, so that all the coupling forces of the male and female coupling members 20, 30 are lost.

[0087] In such a form and structure, generally, it is made difficult to open by the outer opening portion, which is particularly useful as a vinyl zipper bag safety guard for detergents or the like so that children and infants cannot easily open the zipper bag and children and infants cannot come into contact with the contents.

[0088] As described in detail above, even if the present invention is described based on limited embodiments and drawings, the present invention is not limited thereby, and various modifications and variations can be made by those having ordinary knowledge in the technical field to which the present invention pertains within the equivalent scope of the technical idea and claims of the present invention.

[0089] However, it is obvious that such simple modifications and variations cannot fall outside the scope of the rights of the present invention.
