Description

[Technical field]

[0001] The utility model relates to the technical field of sealed packaging, in particular to a ziplock structure and a ziplock bag. [Background technology]

[0002] Zipper bags are widely used in daily life as a common tool for sealing packaging. The zipper structure on the zipper bag is used to facilitate opening and closing. When the zipper structure is closed, the bag body and the closed zipper structure together form a closed space to achieve sealed packaging of the contents, isolating the outside air from the contents, thereby extending the storage time of the contents.

[0003] However, when the zipper structure is closed, the ends corresponding to the male and female chains of the zipper structure are weak links in the seal, which may lead to loose sealing and thus produce gaps, which greatly reduce the sealing performance. Water vapor and bacteria in the air can easily enter, thus affecting the preservation of the contents. [Contents of the utility model]

[0004] In order to solve the problem that the ends corresponding to the male chain and the female chain of the existing clip chain structure are not easily sealed tightly, resulting in poor sealing effect, the utility model provides a clip chain structure and a clip chain bag.

[0005] In order to solve the above technical problems, the utility model provides a clamp chain structure in one embodiment, wherein the clamp chain structure includes a corresponding male chain and a female chain, and the male chain and the female chain can be separated or matched with each other. The clamp chain structure includes an alignment part and a clamping part. The alignment part is arranged at both ends of the clamp chain structure, and the clamping part is arranged between the two alignment parts. The alignment part includes a male alignment part arranged at both ends of the male chain and a female alignment part arranged at both ends of the female chain. The female alignment part is provided with a female alignment groove, and the male alignment part is at least partially cross-arranged in the female alignment groove.

[0006] Preferably, the clamping portion comprises a male clamping piece arranged on the male chain, and the width of the male alignment portion is smaller than the width of the male clamping piece.

[0007] Preferably, the clamping portion also includes a female clamping piece arranged on the female chain, the female clamping piece is provided with a female clamping groove, the male clamping piece includes a root and a protrusion arranged in sequence toward the female clamping groove, the end of the protrusion connected to the root extends outward to form a clamping edge, the width of the clamping edge is greater than the width of the root, and the shape of the female clamping groove corresponds to the shape of the protrusion.

[0008] Preferably, the width of the male alignment portion is smaller than the width of the root, the exposed surface of the root close to one end of the male alignment portion is defined as a step surface, the side of the root close to the clamping edge is a first step side, and the side of the male alignment portion close to the clamping edge is a second step side, and the step surface, the first step side and the second step side constitute a step portion.

[0009] Preferably, the female snap-fitting groove is provided with a receiving cavity corresponding to the snap-fitting edge.

[0010] Preferably, the zipper structure is a silicone zipper structure.

[0011] Preferably, the end of the male alignment portion close to the male snap-in connector is defined as the first end; the end of the male alignment portion away from the male snap-in connector is defined as the second end, and the distance from the first end to the second end is greater than or equal to 3 mm and less than or equal to 12 mm.

[0012] In order to solve the above technical problems, the utility model provides a zipper bag in another embodiment, wherein the zipper bag comprises a bag body and the zipper structure as described above, wherein the bag body comprises a bag sheet, wherein the bag sheet is sealed to form a cavity and an opening connected to the cavity, and the zipper structure is arranged on the inner side surface of the bag sheet close to the opening.

[0013] Preferably, the bag sheet includes a first bag sheet provided with the male chain and a second bag sheet provided with the female chain, and a transition piece is provided at a connection between the first bag sheet and the second bag sheet near the alignment portion.

[0014] Preferably, the number of the clamp chain structures is one group or at least two groups. When the number of the clamp chain structures is at least two groups, the multiple groups of the clamp chain structures are arranged in parallel and adjacent to each other.

[0015] Compared with the prior art, the zipper structure and zipper bag of the utility model have the following advantages:

[0016] 1. The clamp chain structure in one embodiment of the utility model includes a corresponding male chain and a female chain, and the male chain and the female chain can be separated or matched with each other. The clamp chain structure includes an alignment part and a clamping part. The alignment part is arranged at both ends of the clamp chain structure, and the clamping part is arranged between the two alignment parts. The alignment part includes a male alignment part arranged at both ends of the male chain and a female alignment part arranged at both ends of the female chain. The female alignment part is provided with a female alignment groove, and the male alignment part is at least partially cross-arranged in the female alignment groove. By setting the clamp chain structure to include an alignment part and a clamping part, the alignment part is arranged at both ends of the clamp chain structure, and the clamping part is arranged between the two alignment parts, the male chain and the female chain are connected by the clamping part, and the alignment parts at both ends of the clamp chain structure are not clamped but matched by alignment, so as to realize the cross structure of the male alignment part and the female alignment part, fill the gap to strengthen the sealing of the clamp chain structure, so that the clamp chain structure has a better sealing effect, and the cross structure also has a better operating feel when sealing.

[0017] 2. The clamping part in one embodiment of the utility model includes a male clamping part arranged on the male chain, and the width of the male alignment part is smaller than the width of the male clamping part. By setting the width of the male alignment part smaller than the width of the male clamping part, the male alignment part can realize the alignment with the female alignment part more smoothly. The male clamping part reduces a part of the matching thickness through the clamping connection. If the thickness of the male alignment part is consistent with that of the male clamping part, but there is no clamping connection to reduce the matching thickness, the male alignment part can only squeeze the female alignment part outward, and the thickness of the end of the clamp chain structure increases and causes deformation, which makes it easy for gaps to be generated at the end of the clamp chain structure, resulting in reduced sealing. The width of the male alignment part is smaller than the thickness of the male clamping part, so that the male alignment part can be fully accommodated by the female alignment part, and will not squeeze the female alignment part outward to cause a foreign body sensation and generate gaps, thereby improving the sealing effect.

[0018] 3. The clamping part in one embodiment of the utility model also includes a female clamping part arranged on the female chain, the female clamping part is provided with a female clamping groove, the male clamping part includes a root and a protrusion arranged in sequence in the direction of the female clamping groove, the end of the protrusion connected to the root extends outward to form a clamping edge, the width of the clamping edge is greater than the width of the root, and the shape of the female clamping groove corresponds to the shape of the protrusion. Through the above arrangement, the width of the extended clamping edge is greater than the width of the root, and it can be tightly clamped with the female clamping groove, which increases the difficulty of separating the male clamping part from the female clamping part during sealing, and further improves the sealing performance.

[0019] 4. In one embodiment of the utility model, the width of the male counter-positioning part is smaller than the width of the root, and the exposed surface of the root near one end of the male counter-positioning part is defined as a step surface, the side of the root near the clamping edge is a first step side, and the side of the male counter-positioning part near the clamping edge is a second step side. The step surface, the first step side, and the second step side constitute the step portion. Since the width of the male counter-positioning part is smaller than the width of the root, there is an exposed surface at one end of the root near the male counter-positioning part that does not contact the male counter-positioning part, and the exposed surface serves as a step surface. The step surface, the first step side, and the second step side constitute the step portion. When the male chain and the female chain cooperate, the step portion acts as a barrier to prevent the air at the male counter-positioning part from flowing from the step portion to the male clamping part and then penetrating and destroying the sealing effect, thereby effectively improving the sealing performance of the clip chain structure.

[0020] 5. In one embodiment of the utility model, the female snap-fit ​​groove is provided with a receiving cavity corresponding to the snap-fit ​​edge. By providing the female snap-fit ​​groove with a receiving cavity corresponding to the snap-fit ​​edge, the receiving cavity can accommodate the snap-fit ​​edge and abut against the snap-fit ​​edge, so that the snap-fit ​​edge and the receiving cavity form a close snap-fit ​​relationship, thereby improving the sealing and stability of the sealing structure.

[0021] 6. The clip chain structure in one embodiment of the utility model is a silicone clip chain structure. The silicone clip chain structure is made of silicone material, has good sealing performance, is non-toxic and tasteless, will not pollute the food and other contents, and has the advantages of environmental protection and safety.

[0022] 7. In one embodiment of the utility model, the end of the male alignment part close to the male snap-fitting part is defined as the first end; the end of the male alignment part away from the male snap-fitting part is defined as the second end, and the distance from the first end to the second end is greater than or equal to 3 mm and less than or equal to 12 mm. The distance from the first end to the second end is the length of the male alignment part. By limiting the distance from the first end to the second end to be between 3 mm and 12 mm, the length dimension of the male alignment part is further refined. The male alignment part falling within the limited length range can improve the sealing and hand feel of the end of the clip chain structure with a smaller size.

[0023] 8. A zipper bag in one embodiment of the utility model comprises a bag body and the above-mentioned zipper structure, the bag body comprises a bag sheet, the bag sheet is sealed to form a cavity and an opening connected to the cavity, and the zipper structure is arranged on the inner side of the bag sheet close to the opening. The zipper bag and the zipper structure have the same beneficial effects, which will not be described in detail here.

[0024] 9. The bag sheet in one embodiment of the utility model includes a first bag sheet provided with a public chain and a second bag sheet provided with a mother chain, and a transition piece is provided at the connection between the first bag sheet and the second bag sheet near the alignment part. By providing the transition piece at the connection between the first bag sheet and the second bag sheet near the alignment part, the transition piece plays a transition role for the plane where the first bag sheet and the second bag sheet are located, avoiding the direct contact between the first bag sheet and the second bag sheet only at an acute angle, making the transition at the contact point smoother, and providing a larger accommodation space for the alignment piece. The alignment piece will not be squeezed outward due to lack of accommodation space to cause a foreign body sensation, further improving the operational feel of the clip chain structure during the closing operation.

[0025] 10. In one embodiment of the present invention, the number of zipper structures is one group or at least two groups. When the number of zipper structures is at least two groups, multiple groups of zipper structures are arranged in parallel and adjacent to each other. By setting the number of zipper structures to one group, the zipper bag can be opened and closed in the form of a single buckle position, and the single buckle position structure is simple and has low cost. When the number of zipper structures is at least two groups, multiple groups of zipper structures are arranged in parallel and adjacent to each other, so that the zipper bag can form a multi-buckle position form, and multiple groups of zipper structures are arranged in parallel and adjacent to each other to form a multi-layer sealed packaging structure, and the sealing effect of the zipper bag is enhanced.

[0036] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below with reference to the accompanying drawings and implementation examples. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0037] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0038] In the present invention, the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom", "inside", "outside", "middle", "vertical", "horizontal", "lateral", "longitudinal" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings. These terms are mainly used to better describe the present invention and its embodiments, and are not used to limit the indicated devices, elements or components to have a specific orientation, or to be constructed and operated in a specific orientation.

[0039] In addition, some of the above terms may be used to express other meanings in addition to indicating orientation or positional relationship. For example, the term "on" may also be used to express a certain dependency or connection relationship in some cases. For those skilled in the art, the specific meanings of these terms in this utility model can be understood according to specific circumstances.

[0040] In addition, the terms "installed", "set", "provided with", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0041] Please combine Figures 1 to 3 The first embodiment of the utility model provides a clamp chain structure 1, which includes a corresponding male chain 20 and a female chain 30. The male chain 20 and the female chain 30 can be separated or matched with each other. The clamp chain structure 1 includes an alignment part 40 and a clamping part 50. The alignment part 40 is arranged at both ends of the clamp chain structure 1, and the clamping part 50 is arranged between the two alignment parts 40. The alignment part 40 includes a male alignment part 41 arranged at both ends of the male chain 20 and a female alignment part 42 arranged at both ends of the female chain 30. The female alignment part 42 is provided with a female alignment groove 421, and the male alignment part 41 is at least partially cross-arranged in the female alignment groove 421.

[0042] It can be understood that by setting the clamp chain structure 1 to include a positioning part 40 and a clamping part 50, the positioning part 40 is arranged at both ends of the clamp chain structure 1, and the clamping part 50 is arranged between the two positioning parts 40, the male chain 20 and the female chain 30 are clamped and connected by the clamping part 50, and the positioning parts 40 at both ends of the clamp chain structure 1 are aligned to achieve a cross structure in which the male positioning part 41 and the female positioning part 42 cooperate, and the male positioning part 41 is at least partially cross-arranged in the female positioning groove 421. In view of the disadvantage that the ends of the clamp chain structure 1 are the weak links of the seal, it is easy to produce gaps due to poor sealing, which greatly reduces the sealing performance. The cross structure in which the male positioning part 41 and the female positioning part 42 cooperate effectively compensates for the gap and strengthens the sealing performance of the clamp chain structure 1. Better sealing performance can prevent water vapor and bacteria in the air from penetrating the clamp chain structure 1 and contacting food and other contents, causing the contents to deteriorate. The cross structure of the positioning part 40 of the clamp chain structure 1 has a better sealing effect, and the cross structure also has a better operating feel when sealing.

[0043] Please continue to combine Figure 1-Figure 3 Specifically, as a preferred embodiment, the end of the male alignment portion 41 close to the male snap-in connector 51 is defined as the first end 411; the end of the male alignment portion 41 away from the male snap-in connector 51 is defined as the second end 412, and the distance from the first end 411 to the second end 412 is greater than or equal to 3 mm and less than or equal to 12 mm.

[0044] It can be understood that the distance from the first end 411 to the second end 412 is the length of the male alignment portion 41. By limiting the distance from the first end 411 to the second end 412 to be between 3 mm and 12 mm, the length dimension of the male alignment portion 41 is further refined. The male alignment portion 41 falling within the limited length range can improve the sealing and feel of the end of the zipper structure 1 with a smaller size.

[0045] Please continue to combine Figure 1-Figure 3 Further, the snap-fitting portion 50 includes a male snap-fitting piece 51 disposed on the male chain 20 , and the width of the male aligning portion 41 is smaller than the width of the male snap-fitting piece 51 .

[0046] It should be noted that the width of the male snap connector 51 is defined as D, the width of the male alignment portion 41 is defined as d, and the width d of the male alignment portion 41 is less than the width D of the male snap connector 51. It can be understood that by setting the width of the male alignment portion 41 to be smaller than the width of the male snap connector 51, the male alignment portion 41 can be aligned with the female alignment portion 42 more smoothly. The male snap connector 51 reduces a portion of the matching thickness through the snap connection. If the thickness of the male alignment portion 41 is consistent with that of the male snap connector 51, but there is no snap connection to reduce the matching thickness, the male alignment portion 41 can only squeeze the female alignment portion 42 outward, and the thickness of the end of the clip chain structure 1 increases and causes deformation, resulting in a gap at the end of the clip chain structure 1, resulting in a decrease in sealing. The width of the male alignment portion 41 is smaller than the thickness of the male snap connector 51, so that the male alignment portion 41 can be fully accommodated by the female alignment portion 42, and will not squeeze the female alignment portion 42 outward to cause a foreign body sensation and a gap, thereby improving the sealing effect.

[0047] Please continue to combine Figure 1-Figure 3 Furthermore, the clamping portion 50 also includes a female clamping piece 52 arranged on the female chain 30, and the female clamping piece 52 is provided with a female clamping groove 521. The male clamping piece 51 includes a root 211 and a protrusion 212 which are arranged in sequence toward the female clamping groove 521. One end of the protrusion 212 connected to the root 211 extends outward to form a clamping edge 213. The width of the clamping edge 213 is greater than the width of the root 211. The shape of the female clamping groove 521 corresponds to the shape of the protrusion 212.

[0048] It can be understood that by opening a female snap-in groove 521 in the female snap-in component 52, the female snap-in groove 521 can cooperate with the male snap-in component 51 to improve the stability of the snap-in structure; the width of the snap-in edge 213 extending from the male snap-in component 51 is greater than the width of the root 211, and can be tightly snap-fitted with the female snap-in groove 521, thereby increasing the difficulty of separating the male snap-in component 51 and the female snap-in component 52 during sealing. , Further improve the sealing performance.

[0049] Please combine Figure 2-Figure 3Furthermore, the width of the male alignment portion 41 is smaller than the width of the root 211, and the exposed surface of the root 211 close to one end of the male alignment portion 41 is defined as a step surface 531, the side of the root 211 close to the clamping edge 213 is a first step side surface 532, and the side of the male alignment portion 41 close to the clamping edge 213 is a second step side surface 533. The step surface 531, the first step side surface 532 and the second step side surface 533 constitute a step portion.

[0050] It should be noted that the width of the root 211 is defined as S, and the width d of the male alignment portion 41 is less than the root width S. It can be understood that since the width of the male alignment portion 41 is smaller than the width of the root 211, the end face of the root 211 close to the male alignment portion 41 does not completely fit the male alignment portion 41, but there is an exposed surface that does not contact the male alignment portion 41, and the exposed surface serves as a step surface 531, and the step surface 531, the first step side surface 532 and the second step side surface 533 constitute the step portion 53. When the male chain 20 and the female chain 30 cooperate, the step portion 53 acts as a barrier to prevent air from flowing from the male alignment portion 41 through the step portion 53 to the male snap-on component 51 and then penetrating and destroying the sealing effect, thereby effectively improving the sealing performance of the clip chain structure 1.

[0051] See also Figure 3 Furthermore, the width of the protrusion 212 gradually decreases in a direction away from the root 211.

[0052] It can be understood that by setting the width of the protrusion 212 to gradually decrease in the direction away from the root 211, the protrusion 212 has a larger width dimension at the end close to the root 211, and the larger width dimension makes the protrusion 212 cooperate with the female clamping groove 521 to play a better limiting role, so that it is not easy to fall off and separate; a top with a smaller width dimension is formed at the end away from the root 211, and the top structure is relatively sharp, so that the protrusion 212 enters the female clamping groove 521 more smoothly. The above configuration enables the protrusion 212 and the female clamping groove 521 to establish a connection relationship that is convenient to operate and has a stable seal.

[0053] Please combine Figure 2 and Figure 3 Furthermore, the female snap-fitting groove 521 defines a receiving cavity 311 corresponding to the snap-fitting edge 213 .

[0054] It can be understood that by opening a accommodating cavity 311 corresponding to the snap-fitting edge 213 in the female snap-fitting groove 521, the accommodating cavity 311 can accommodate the snap-fitting edge 213 and abut against the snap-fitting edge 213, so that the snap-fitting edge 213 and the accommodating cavity 311 form a tight snap-fitting relationship, thereby improving the sealing and fitting stability of the sealing structure.

[0055] See also Figure 1Furthermore, the zipper structure 1 is a silicone zipper structure. The silicone zipper structure is made of silicone material, has good sealing performance, is non-toxic and tasteless, will not pollute the food and other contents, and has the advantages of environmental protection and safety.

[0056] See also Figure 4 The second embodiment of the utility model provides a zipper bag 100, which includes a bag body 110 and a zipper structure 1. The bag body 110 includes a bag sheet 111, and the bag sheet 111 is sealed to form a cavity 112 and an opening 113 connected to the cavity 112. The zipper structure 1 is arranged on the inner side of the bag sheet 111 close to the opening 113.

[0057] It can be understood that the zipper bag 100 has the same beneficial effects as the zipper structure 1. The zipper structure 1 and the bag body 110 seal the zipper bag 100 together. The zipper bag 100 has a good sealing effect and can effectively block air from entering the food and other contents, preventing the contents from coming into contact with water vapor and bacteria in the air and deteriorating and becoming moldy. There is no foreign body sensation during the sealing operation, which improves the user's operating feel when sealing the zipper bag 100. As a specific embodiment, the zipper bag 100 is made of silicone material. The silicone material makes the zipper bag 100 have good sealing performance and the advantages of being non-toxic and tasteless. It will not pollute and odor the food and other contents, is more environmentally friendly and safe, and will not be easily torn and deformed. Therefore, it is very safe and reliable to use it to store food, keep it fresh and prevent odor.

[0058] Please continue reading Figure 4 Furthermore, the bag piece 111 includes a first bag piece 1111 provided with a male chain 20 and a second bag piece 1112 provided with a female chain 30 , and a transition piece 114 is provided at a connection between the first bag piece 1111 and the second bag piece 1112 near the alignment portion 40 .

[0059] It can be understood that by arranging a transition piece 114 at the connection between the first bag sheet 1111 and the second bag sheet 1112 near the alignment portion 40, the transition piece 114 plays a transition role for the plane where the first bag sheet 1111 and the second bag sheet 1112 are located, avoiding direct contact between the first bag sheet 1111 and the second bag sheet 1112 only at an acute angle, making the transition at the contact point smoother, and providing a larger accommodating space for the alignment piece. The alignment piece will not be squeezed outward due to lack of accommodating space to cause a foreign body sensation, further improving the operational feel of the zipper structure 1 during the closing operation.

[0060] Please combine Figure 5 and Figure 6 Furthermore, the number of the clamp chain structures 1 is one group or at least two groups. When the number of the clamp chain structures 1 is at least two groups, the multiple groups of clamp chain structures 1 are arranged in parallel and adjacent to each other.

[0061] It should be noted that when the number of zipper structures 1 is one group, the zipper bag 100 is a single-buckle type; when the number of zipper structures 1 is multiple groups, the zipper bag 100 is a multiple-buckle type. The more zipper structures 1 there are, the better the sealing of the zipper bag 100. However, the manufacturing cost of the zipper bag 100 and the difficulty of opening the zipper bag 100 will increase with the increase in the number of zipper structures 1. Therefore, the specific number of zipper structures 1 needs to be balanced between sealing, cost, and difficulty of opening. As a specific implementation method, the number of zipper structures 1 is one group, Figure 5 This embodiment is shown in the form of a cross-sectional view; as another specific embodiment, the number of the clip chain structures 1 is two groups, and the two groups of clip chain structures 1 are arranged in parallel and adjacent to each other. Figure 6 This embodiment is shown in the form of a cross-sectional view. The above are all examples, and the number of other clip chain structures 1 is not limited here.

[0062] It can be understood that by setting the number of zipper structures 1 to one group, the zipper bag 100 can be opened and closed in the form of a single buckle position, and the single buckle position structure is simple and has low cost. When the number of zipper structures 1 is set to at least two groups, multiple groups of zipper structures 1 are arranged in parallel and adjacent to each other, so that the zipper bag 100 can form a multi-buckle position form, and multiple groups of zipper structures 1 are arranged in parallel and adjacent to each other to form a multi-layer sealed packaging structure, and the sealing effect of the zipper bag 100 is enhanced.

[0063] Compared with the prior art, the zipper structure and zipper bag of the utility model have the following advantages:

[0064] 1. The clamp chain structure in one embodiment of the utility model includes a corresponding male chain and a female chain, and the male chain and the female chain can be separated or matched with each other. The clamp chain structure includes an alignment part and a clamping part. The alignment part is arranged at both ends of the clamp chain structure, and the clamping part is arranged between the two alignment parts. The alignment part includes a male alignment part arranged at both ends of the male chain and a female alignment part arranged at both ends of the female chain. The female alignment part is provided with a female alignment groove, and the male alignment part is at least partially cross-arranged in the female alignment groove. By setting the clamp chain structure to include an alignment part and a clamping part, the alignment part is arranged at both ends of the clamp chain structure, and the clamping part is arranged between the two alignment parts, the male chain and the female chain are connected by the clamping part, and the alignment parts at both ends of the clamp chain structure are not clamped but matched by alignment, so as to realize the cross structure of the male alignment part and the female alignment part, fill the gap to strengthen the sealing of the clamp chain structure, so that the clamp chain structure has a better sealing effect, and the cross structure also has a better operating feel when sealing.

[0065] 2. The clamping part in one embodiment of the utility model includes a male clamping part arranged on the male chain, and the width of the male alignment part is smaller than the width of the male clamping part. By setting the width of the male alignment part smaller than the width of the male clamping part, the male alignment part can realize the alignment with the female alignment part more smoothly. The male clamping part reduces a part of the matching thickness through the clamping connection. If the thickness of the male alignment part is consistent with that of the male clamping part, but there is no clamping connection to reduce the matching thickness, the male alignment part can only squeeze the female alignment part outward, and the thickness of the end of the clamp chain structure increases and causes deformation, which makes it easy for gaps to be generated at the end of the clamp chain structure, resulting in reduced sealing. The width of the male alignment part is smaller than the thickness of the male clamping part, so that the male alignment part can be fully accommodated by the female alignment part, and will not squeeze the female alignment part outward to cause a foreign body sensation and generate gaps, thereby improving the sealing effect.

[0066] 3. The clamping part in one embodiment of the utility model also includes a female clamping part arranged on the female chain, the female clamping part is provided with a female clamping groove, the male clamping part includes a root and a protrusion arranged in sequence in the direction of the female clamping groove, the end of the protrusion connected to the root extends outward to form a clamping edge, the width of the clamping edge is greater than the width of the root, and the shape of the female clamping groove corresponds to the shape of the protrusion. Through the above arrangement, the width of the extended clamping edge is greater than the width of the root, and it can be tightly clamped with the female clamping groove, which increases the difficulty of separating the male clamping part from the female clamping part during sealing, and further improves the sealing performance.

[0067] 4. In one embodiment of the utility model, the width of the male counter-positioning part is smaller than the width of the root, and the exposed surface of the root near one end of the male counter-positioning part is defined as a step surface, the side of the root near the clamping edge is a first step side, and the side of the male counter-positioning part near the clamping edge is a second step side. The step surface, the first step side, and the second step side constitute the step portion. Since the width of the male counter-positioning part is smaller than the width of the root, there is an exposed surface at one end of the root near the male counter-positioning part that does not contact the male counter-positioning part, and the exposed surface serves as a step surface. The step surface, the first step side, and the second step side constitute the step portion. When the male chain and the female chain cooperate, the step portion acts as a barrier to prevent the air at the male counter-positioning part from flowing from the step portion to the male clamping part and then penetrating and destroying the sealing effect, thereby effectively improving the sealing performance of the clip chain structure.

[0068] 5. In one embodiment of the utility model, the female snap-fit ​​groove is provided with a receiving cavity corresponding to the snap-fit ​​edge. By providing the female snap-fit ​​groove with a receiving cavity corresponding to the snap-fit ​​edge, the receiving cavity can accommodate the snap-fit ​​edge and abut against the snap-fit ​​edge, so that the snap-fit ​​edge and the receiving cavity form a close snap-fit ​​relationship, thereby improving the sealing and stability of the sealing structure.

[0069] 6. The clip chain structure in one embodiment of the utility model is a silicone clip chain structure. The silicone clip chain structure is made of silicone material, has good sealing performance, is non-toxic and tasteless, will not pollute the food and other contents, and has the advantages of environmental protection and safety.

[0070] 7. In one embodiment of the present invention, the end of the male alignment part close to the male snap-fitting part is defined as the first end; the end of the male alignment part away from the male snap-fitting part is defined as the second end, and the distance from the first end to the second end is greater than or equal to 3 mm and less than or equal to 12 mm. The distance from the first end to the second end is the length of the male alignment part. By defining the distance from the first end to the second end to be between 3 mm and 12 mm, the length dimension of the male alignment part is further refined. The male alignment part falling within the defined length range can improve the sealing and hand feel of the end of the clip chain structure with a smaller size.

[0071] 8. A zipper bag in one embodiment of the utility model comprises a bag body and the above-mentioned zipper structure, the bag body comprises a bag sheet, the bag sheet is sealed to form a cavity and an opening connected to the cavity, and the zipper structure is arranged on the inner side of the bag sheet close to the opening. The zipper bag and the zipper structure have the same beneficial effects, which will not be described in detail here.

[0072] 9. The bag sheet in one embodiment of the utility model includes a first bag sheet provided with a public chain and a second bag sheet provided with a mother chain, and a transition piece is provided at the connection between the first bag sheet and the second bag sheet near the alignment part. By providing the transition piece at the connection between the first bag sheet and the second bag sheet near the alignment part, the transition piece plays a transition role for the plane where the first bag sheet and the second bag sheet are located, avoiding the direct contact between the first bag sheet and the second bag sheet only at an acute angle, making the transition at the contact point smoother, and providing a larger accommodation space for the alignment piece. The alignment piece will not be squeezed outward due to lack of accommodation space to cause a foreign body sensation, further improving the operational feel of the clip chain structure during the closing operation.

[0073] 10. In one embodiment of the present invention, the number of zipper structures is one group or at least two groups. When the number of zipper structures is at least two groups, multiple groups of zipper structures are arranged in parallel and adjacent to each other. By setting the number of zipper structures to one group, the zipper bag can be opened and closed in the form of a single buckle position, and the single buckle position structure is simple and has low cost. When the number of zipper structures is at least two groups, multiple groups of zipper structures are arranged in parallel and adjacent to each other, so that the zipper bag can form a multi-buckle position form, and multiple groups of zipper structures are arranged in parallel and adjacent to each other to form a multi-layer sealed packaging structure, and the sealing effect of the zipper bag is enhanced.

[0074] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the principles of the present invention should be included in the protection scope of the present invention.
