Description

Technical Field

[0001] The present invention relates to the technical field of sealed packaging, and particularly to a chuck structure and a bag with a chuck.

Background Art

[0002] Bags with chucks are widely used as common tools for sealed packaging. The chuck structure in a bag with a chuck is used to easily open and close the seal. When the chuck structure is closed, the bag body forms a sealed space together with the closed chuck structure, realizing the sealed packaging of the contents, blocking the contact between the outside air and the contents, and extending the storage period of the contents.

[0003] However, when the chuck structure is closed, the end portion of the male chuck corresponding to the female chuck of the chuck structure becomes a sealing neck, and it is easy to have poor sealing. As a result, gaps are generated and the sealing performance is greatly reduced, making it easy for water vapor and bacteria in the air to invade, which affects the storage effect of the contents.

Summary of the Invention

Problems to be Solved by the Invention

[0004] In order to solve the problem that the end portion of the male chuck of the conventional chuck structure corresponding to the female chuck is likely to have poor sealing and the sealing effect is relatively poor, the present invention provides a chuck structure and a bag with a chuck.

Means for Solving the Problems

[0005] In order to solve the above problems, in one embodiment, the present invention provides a chuck structure, which includes a corresponding male chuck and female chuck. The male chuck and the female chuck can be separated from or engaged with each other. The chuck structure includes an alignment portion provided at both ends of the chuck structure and a fastening portion provided between the two alignment portions. The alignment portion includes a male alignment portion provided at both ends of the male chuck and a female alignment portion provided at both ends of the female chuck. A female alignment groove is formed in the female alignment portion, and at least a part of the male alignment portion is provided to intersect within the female alignment groove.

[0006] Preferably, the fastening portion includes a male fastening member provided on the male chuck, and the width of the male alignment portion is smaller than the width of the male fastening member.

[0007] Preferably, the fastening portion further includes a female fastening member provided on the female chuck. A female fastening groove is formed in the female fastening member. The male fastening member includes a root portion and a protrusion portion provided in sequence in the direction of the female fastening groove. One end of the protrusion portion connected to the root portion extends outward to form a fastening ridge portion. The width of the fastening ridge portion is larger than the width of the root portion, and the shape of the female fastening groove corresponds to the shape of the protrusion portion.

[0008] Preferably, the width of the male alignment portion is smaller than the width of the root portion. The exposed surface of one end of the root portion close to the male alignment portion is a stepped surface. The side surface of the root portion close to the fastening ridge portion is a first stepped side surface. The side surface of the male alignment portion close to the fastening ridge portion is a second stepped side surface. The stepped surface, the first stepped side surface, and the second stepped side surface constitute a stepped portion.

[0009] Preferably, a receiving chamber corresponding to the fastening ridge portion is formed in the female fastening groove.

[0010] Preferably, the chuck structure is a silica gel chuck structure.

[0011] Preferably, one end of the male alignment portion close to the male engaging member is defined as the first end, and one end of the male alignment portion away from the male engaging member is defined as the second end. The distance from the first end to the second end is 3 mm or more and 12 mm or less.

[0012] In order to solve the above problems, in another embodiment, the present invention provides a bag with a chuck. The bag with a chuck includes a bag body and the above-mentioned chuck structure. The bag body includes a bag sheet. By sealing the bag sheet, a cavity and an opening communicating with the cavity are formed. The chuck structure is provided on one side of the inner surface of the bag sheet close to the opening.

[0013] Preferably, the bag sheet includes a first bag sheet provided with the male chuck and a second bag sheet provided with the female chuck. A delivery material is provided at a connection location near the alignment portion of the first bag sheet and the second bag sheet.

[0014] Preferably, the number of the chuck structures is one group or at least two groups. When the number of the chuck structures is at least two groups, the plurality of groups of the chuck structures are provided adjacent to each other in parallel.

Advantages of the Invention

[0015] Compared with the prior art, the chuck structure and the bag with a chuck of the present invention have the following advantages.

[0016] 1. The chuck structure in one embodiment of the present invention includes a corresponding male chuck and female chuck, which can be separated or fitted with each other. The chuck structure includes an alignment portion provided at both ends of the chuck structure and an engagement portion provided between the two alignment portions. The alignment portion includes a male alignment portion provided at both ends of the male chuck and a female alignment portion provided at both ends of the female chuck. A female alignment groove is formed in the female alignment portion, and at least a part of the male alignment portion is provided to intersect within the female alignment groove. The chuck structure includes an alignment portion and an engagement portion. The alignment portion is provided at both ends of the chuck structure, and the engagement portion is provided between the two alignment portions. The male chuck and the female chuck are engaged and connected by the engagement portion. On the other hand, the alignment portions located at both ends of the chuck structure are not engaged but are fitted by alignment, realizing an intersection structure where the male alignment portion and the female alignment portion are fitted, complementing the gap and strengthening the sealing performance of the chuck structure. The chuck structure has a better sealing effect, and the intersection structure also has a better operating feel during sealing.

[0017] 2. The engagement portion in one embodiment of the present invention includes a male engagement member provided on the male chuck, and the width of the male alignment portion is smaller than the width of the male engagement member. By setting the width of the male alignment portion to be smaller than the width of the male engagement member, the male alignment portion can relatively smoothly achieve alignment with the female alignment portion. The male engagement member reduces a part of the fitting thickness by engagement connection. Although the thickness of the male alignment portion and the male engagement member is the same, if the fitting thickness is not reduced by engagement connection, the male alignment portion will push the female alignment portion outwards, increasing and deforming the thickness of the end of the chuck structure, and it is easy to generate a gap at the end of the chuck structure, reducing the sealing performance. Since the width of the male alignment portion is smaller than the thickness of the male engagement member, the male alignment portion can be fully accommodated in the female alignment portion, without generating a foreign body feeling and gap caused by pushing the female alignment portion outwards, improving the sealing effect.

[0018] 3. In one embodiment of the present invention, the fastening part further includes a female fastener provided on the female zipper, the female fastener has a female fastening groove, the male fastener includes a root and a protrusion provided in order toward the female fastening groove, one end of the protrusion connected to the root is extended outward to form a fastening ridge, the width of the fastening ridge is greater than the width of the root, and the shape of the female fastening groove corresponds to the shape of the protrusion. With the above arrangement, the width of the extended and protruding fastening ridge is greater than the width of the root, so that it can be tightly engaged with the female fastening groove, which increases the difficulty of separating the male fastener and the female fastener during sealing and fitting, and further improves the sealing performance.

[0019] 4. In one embodiment of the present invention, the width of the male alignment part is smaller than the width of the root part, the exposed surface of one end of the root part close to the male alignment part is the step surface, the side of the root part close to the engagement ridge is the first step side, the side of the male alignment part close to the engagement ridge is the second step side, and the step surface, the first step side and the second step side constitute the step part. Since the width of the male alignment part is smaller than the width of the root part, there is an exposed surface of one end of the root part close to the male alignment part that does not contact the male alignment part, the exposed surface is the step surface, and the step surface, the first step side and the second step side constitute the step part. When the male zipper and the female zipper are mated, the step part acts as a barrier, preventing air in the male alignment part from flowing from the step part to the male fastener and further penetrating and destroying the sealing effect, effectively improving the sealing performance of the zipper structure.

[0020] 5. In one embodiment of the present invention, the female engaging groove is provided with an accommodating chamber corresponding to the engaging ridge, so that the accommodating chamber can accommodate the engaging ridge and abut against the engaging ridge, and the engaging ridge and the accommodating chamber form a tight engaging and fitting relationship, which improves the sealing performance and stability of the sealing structure.

[0021] 6. The chuck structure in one embodiment of the present invention is a silica gel chuck structure. The silica gel chuck structure adopts a silica gel material, has relatively excellent sealing performance, is non-toxic and odorless, and has the advantages of not causing contamination or odor transfer to contents such as food, being environmentally friendly and safe.

[0022] 7. In one embodiment of the present invention, one end close to the male engaging member of the male alignment portion is defined as the first end, and one end away from the male engaging member of the male alignment portion is defined as the second end. The distance from the first end to the second end is 3 mm or more and 12 mm or less. The distance from the first end to the second end is the length of the male alignment portion. 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 portion can be further accurately limited. The male alignment portion within the limited length range can improve the sealing performance and feel of the end of the chuck structure with relatively small dimensions.

[0023] 8. The bag with a chuck in one embodiment of the present invention includes a bag body and the above-mentioned chuck structure. The bag body includes a bag sheet. By sealing the bag sheet, a cavity and an opening communicating with the cavity are formed. The chuck structure is provided on one side of the inner surface of the bag sheet close to the opening. The bag with a chuck and the chuck structure have the same beneficial effects and will not be further described here.

[0024] 9. The bag sheet in one embodiment of the present invention includes a first bag sheet provided with a male chuck and a second bag sheet provided with a female chuck, and a delivery material is provided at a connection location near the alignment portion of the first bag sheet and the second bag sheet. By providing the delivery material at a connection location near the alignment portion of the first bag sheet and the second bag sheet, the delivery material serves the role of delivery with respect to the plane where the first bag sheet and the second bag sheet are located, avoiding the situation where the first bag sheet and the second bag sheet simply come into direct contact at an acute angle, allowing the contact location to be delivered more gently, providing a larger accommodation space by the alignment material, preventing the alignment material from being pushed out due to insufficient accommodation space and causing a foreign body sensation, and further improving the operation feeling when closing the chuck structure.

[0025] 10. The number of chuck structures in one embodiment of the present invention is one group or at least two groups. When the number of chuck structures is at least two groups, the multiple groups of chuck structures are provided adjacent to each other in parallel. By setting the number of chuck structures to one group, the bag with a chuck can achieve the opening and closing of sealed packaging by a single engaging portion, and the single engaging portion has a simple structure and relatively low cost. When setting the number of chuck structures to at least two groups, the multiple groups of chuck structures are provided adjacent to each other in parallel, and the bag with a chuck can form multiple engaging portions. The multiple groups of chuck structures are provided adjacent to each other in parallel to form a multi-layer sealed packaging structure, and the sealing effect of the bag with a chuck is enhanced.

Embodiments for Carrying out the Invention

[0028] To make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described here are only used to interpret the present invention and are not intended to limit the present invention.

[0029] 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 an intermediate element may exist. When an element is considered to be "connected" to another element, it may be directly connected to the other element or an intermediate element may exist simultaneously. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this specification are only used for the purpose of explanation.

[0030] In the present invention, the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "front", "rear", "top", "bottom", "inner", "outer", "middle", "vertical", "horizontal", "lateral direction", and "longitudinal direction" is based on the orientation or positional relationship shown in the drawings. These terms are mainly for better describing the present invention and its embodiments, and are not intended to limit that the indicated device, element, or component must necessarily have a specific orientation or be configured and operated in a specific orientation.

[0031] And some of the above terms can represent other meanings in addition to being used to represent the orientation or positional relationship. For example, the term "upper" can, in some cases, be used to represent a dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in the present invention according to the specific situation.

[0032] It should be noted that the terms "attach", "install", "be provided", "connect", and "be connected" should be understood in a broad sense. For example, it may be a fixed connection, a removable connection, or an integral structure, may be mechanically connected, or may be electrically connected, may be directly connected, or may be indirectly connected through an intermediate medium, or may be an internal communication between two devices, elements, or components. Those skilled in the art can understand the specific meaning of the above terms in the present invention according to the specific situation.

[0033] Combining FIGS. 1 to 3, the first embodiment of the present invention provides a chuck structure 1, and the chuck structure 1 includes a corresponding male chuck 20 and female chuck 30. The male chuck 20 and the female chuck 30 can be separated from or fitted to each other. The chuck structure 1 includes an alignment portion 40 provided at both ends of the chuck structure 1 and an engagement portion 50 provided between the two alignment portions 40. The alignment portion 40 includes a male alignment portion 41 provided at both ends of the male chuck 20 and a female alignment portion 42 provided at both ends of the female chuck 30. A female alignment groove 421 is formed in the female alignment portion 42, and at least a part of the male alignment portion 41 is provided to intersect within the female alignment groove 421.

[0034] It should be noted that the width of the male engaging member 51 is D, the width of the male alignment portion 41 is d, and the width d of the male alignment portion 41 < the width D of the male engaging member 51. The chuck structure 1 includes an alignment portion 40 and an engagement portion 50. The alignment portion 40 is provided at both ends of the chuck structure 1, the engagement portion 50 is provided between the two alignment portions 40, the male chuck 20 and the female chuck 30 are engaged and connected by the engagement portion 50, and the alignment portions 40 located at both ends of the chuck structure 1 are fitted by alignment to realize an intersection structure in which the male alignment portion 41 and the female alignment portion 42 are fitted, and at least a part of the male alignment portion 41 is provided to intersect within the female alignment groove 421. With respect to the drawback that the end of the chuck structure 1 is a sealed neck and a gap is generated due to poor sealing, resulting in a significant decrease in sealing performance, the intersection structure in which the male alignment portion 41 and the female alignment portion 42 are fitted can effectively compensate for the gap and enhance the sealing performance of the chuck structure 1. The relatively excellent sealing performance can prevent water vapor and bacteria in the air from passing through the chuck structure 1 and contacting the contents such as food, thereby avoiding the deterioration of the contents. The intersection structure of the alignment portion 40 of the chuck structure 1 has a better sealing effect, and the intersection structure also has a better operating feel during sealing.

[0035] Subsequently, by combining FIGS. 1 to 3, specifically, in one preferred embodiment, one end of the male alignment portion 41 close to the male engaging member 51 is defined as the first end 411, and one end of the male alignment portion 41 away from the male engaging member 51 is defined as the second end 412. The distance from the first end 411 to the second end 412 is 3 mm or more and 12 mm or less.

[0036] As can be understood, 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 accurately limited. The male alignment portion 41 within the limited length range can improve the sealing performance and feel at the end of the chuck structure 1 with relatively small dimensions.

[0037] Subsequently, by combining FIGS. 1 to 3, further, the engaging portion 50 includes a male engaging member 51 provided on the male chuck 20, and the width of the male alignment portion 41 is smaller than the width of the male engaging member 51.

[0038] As can be understood, let the width of the male engaging member 51 be D and the width of the male alignment portion 41 be d, and d < D. By setting the width of the male alignment portion 41 to be smaller than the width of the male engaging member 51, the male alignment portion 41 can relatively smoothly align with the female alignment portion 42. The male engaging member 51 reduces a part of the fitting thickness by engaging connection. Although the thickness of the male alignment portion 41 is the same as that of the male engaging member 51, if the fitting thickness is not reduced by the engaging connection, the male alignment portion 41 will push the female alignment portion 42 outwards, the thickness at the end of the chuck structure 1 will increase and deform, gaps are likely to occur at the end of the chuck structure 1, and the sealing performance will decrease. Since the width of the male alignment portion 41 is smaller than the thickness of the male engaging member 51, the male alignment portion 41 can be fully accommodated in the female alignment portion 42, there will be no foreign body sensation and generation of gaps due to pushing the female alignment portion 42 outwards, and the sealing effect is improved.

[0039] Subsequently, combining FIGS. 1 to 3, further, the engaging portion 50 further includes a female engaging member 52 provided on the female chuck 30. A female engaging groove 521 is formed in the female engaging member 52. The male engaging member 51 includes a root portion 211 and a protrusion portion 212 provided in sequence in the direction of the female engaging groove 521. One end connected to the root portion 211 of the protrusion portion 212 extends outward to form an engaging ridge portion 213. The width of the engaging ridge portion 213 is larger than the width of the root portion 211. The shape of the female engaging groove 521 corresponds to the shape of the protrusion portion 212.

[0040] As can be understood, by forming the female engaging groove 521 in the female engaging member 52, the female engaging groove 521 is fitted to the male engaging member 51, improving the stability of the engaging structure. The width of the extended and protruding engaging ridge portion 213 of the male engaging member 51 is larger than the width of the root portion 211, and it can be tightly engaged with the female engaging groove 521, increasing the difficulty of separation between the male engaging member 51 and the female engaging member 52 during sealing fitting and further improving the sealing performance.

[0041] Combining FIGS. 2 to 3, further, the width of the male alignment portion 41 is smaller than the width of the root portion 211. The exposed surface of one end of the root portion 211 close to the male alignment portion 41 is taken as a stepped surface 531. The side surface of the root portion 211 close to the engaging ridge portion 213 is taken as a first stepped side surface 532. The side surface of the male alignment portion 41 close to the engaging ridge portion 213 is taken as a second stepped side surface 533. The stepped surface 531, the first stepped side surface 532, and the second stepped side surface 533 constitute a stepped portion.

[0042] It should be noted that the width of the root part 211 is set as S, and the width d of the male alignment part 41 < the width S of the root part. As can be understood, since the width of the male alignment part 41 is smaller than the width of the root part 211, the end face of one end of the root part 211 close to the male alignment part 41 does not completely adhere to the male alignment part 41, and there is an exposed surface that does not contact the male alignment part 41. The exposed surface is used as the stepped surface 531, and the stepped surface 531, the first stepped side surface 532 and the second stepped side surface 533 constitute the stepped part 53. When the male chuck 20 and the female chuck 30 are fitted, the stepped part 53 plays the role of a barrier, preventing air from flowing from the male alignment part 41 through the stepped part 53 to the male engaging material 51 and further penetrating to destroy the sealing effect, and effectively improving the sealing performance of the chuck structure 1.

[0043] Referring to FIG. 3, further, the width of the protrusion 212 gradually decreases along the direction away from the root part 211.

[0044] As can be understood, by providing the width of the protrusion 212 to gradually decrease along the direction away from the root part 211, one end of the protrusion 212 close to the root part 211 has a relatively large width dimension. Due to the relatively large width dimension, the protrusion 212 and the female engaging groove 521 are fitted to exert a better stopper function, making it difficult to separate and disengage. A top part with a relatively small width dimension is formed at one end away from the root part 211. Since the top part structure is relatively sharp, it becomes smoother when the protrusion 212 enters the female engaging groove 521. With the above arrangement, the protrusion 212 and the female engaging groove 521 establish a connection relationship that is convenient to operate and has stable sealing.

[0045] Combining FIG. 2 and FIG. 3, further, a receiving chamber 311 corresponding to the engaging ridge part 213 is opened in the female engaging groove 521.

[0046] As can be understood, by opening the receiving chamber 311 corresponding to the engaging ridge part 213 in the female engaging groove 521, the receiving chamber 311 can accommodate the engaging ridge part 213 and abut against the engaging ridge part 213. A tight engaging and fitting relationship is formed between the engaging ridge part 213 and the receiving chamber 311, improving the sealing performance and fitting stability of the sealing structure.

[0047] Referring to FIG. 1, further, the chuck structure 1 is a silica gel chuck structure. The silica gel chuck structure adopts a silica gel material and has relatively excellent sealing performance, and is non-toxic and odorless. It has the advantages that it will not cause contamination or odor transfer to contents such as food, is environmentally friendly and safe.

[0048] Referring to FIG. 4, the second embodiment of the present invention provides a bag 100 with a chuck. The bag 100 with a chuck includes a bag body 110 and a chuck structure 1. The bag body 110 includes a bag sheet 111. By sealing the bag sheet 111, a cavity 112 and an opening 113 communicating with the cavity 112 are formed. The chuck structure 1 is provided on one side close to the opening 113 on the inner surface of the bag sheet 111.

[0049] As can be understood, the bag 100 with a chuck and the chuck structure 1 have the same beneficial effects. The chuck structure 1 closes the bag 100 with a chuck together with the bag body 110. The bag 100 with a chuck has a good sealing effect and can effectively prevent air from entering contents such as food, and prevent the contents from deteriorating or getting moldy due to contact with water vapor and bacteria in the air. And there is no foreign body feeling during the sealing operation, which improves the operation feeling when the user seals the bag 100 with a chuck. As a specific embodiment, the bag 100 with a chuck adopts a silica gel material. Due to the silica gel material, the bag 100 with a chuck has the advantages of relatively excellent sealing performance and being non-toxic and odorless. It will not cause contamination or odor transfer to contents such as food, is environmentally friendly and safe, and will not tear or deform. Therefore, when it is used for storing or preserving food and preventing odor transfer, it is very safe and reliable.

[0050] Subsequently, referring to FIG. 4, further, the bag sheet 111 includes a first bag sheet 1111 provided with a male chuck 20 and a second bag sheet 1112 provided with a female chuck 30. A transfer material 114 is provided at a connection location close to the alignment portion 40 of the first bag sheet 1111 and the second bag sheet 1112.

[0051] To be understandable, by providing the transfer material 114 at a connection location close to the alignment portion 40 of the first bag sheet 1111 and the second bag sheet 1112, the transfer material 114 serves the role of transfer with respect to the plane where the first bag sheet 1111 and the second bag sheet 1112 are located, avoiding the situation where the first bag sheet 1111 and the second bag sheet 1112 simply contact directly at an acute angle, making the contact location be transferred more gently, being able to provide a larger accommodation space by the alignment material, preventing the alignment material from being pushed out due to the lack of accommodation space and causing a foreign body sensation, and further improving the operation feeling when closing the chuck structure 1.

[0052] Combining FIG. 5 and FIG. 6, further, the number of the chuck structures 1 is one group or at least two groups. When the number of the chuck structures 1 is at least two groups, the multiple groups of chuck structures 1 are provided adjacent to each other in parallel.

[0053] It should be noted that when the number of the chuck structures 1 is one group, the bag 100 with a chuck is of a single engagement portion type. When the number of the chuck structures 1 is multiple groups, the bag 100 with a chuck is of a multiple engagement portion type. The more the number of the chuck structures 1 is, the better the sealing performance of the bag 100 with a chuck is. However, the manufacturing cost of the bag 100 with a chuck and the difficulty of opening the bag 100 with a chuck increase with the increase in the number of the chuck structures 1. Therefore, the specific number of the chuck structures 1 needs to be selected in a well-balanced manner considering the sealing performance, cost, and difficulty of opening. As one specific embodiment, the number of the chuck structures 1 is one group, and FIG. 5 shows this embodiment by a cross-sectional view. As another specific embodiment, the number of the chuck structures 1 is two groups, and the two groups of chuck structures 1 are provided adjacent to each other in parallel, and FIG. 6 shows this embodiment by a cross-sectional view. The above is described by way of enumeration, and the number of other chuck structures 1 is not limited here.

[0054] As can be understood, by setting the number of the chuck structures 1 into one group, the bag 100 with a chuck can realize the opening and closing of the sealed package in the form of a single engaging portion, and the single engaging portion has a simple structure and a relatively low cost. When the number of the chuck structures 1 is set to at least two groups, the plurality of groups of chuck structures 1 are provided adjacent to each other in parallel, and the bag 100 with a chuck can form a plurality of engaging portions. The plurality of groups of chuck structures 1 are provided adjacent to each other in parallel to form a multi-layer sealed packaging structure, and the sealing effect of the bag 100 with a chuck is enhanced.

[0055] In connection with FIGS. 7, 8, and 9, in another embodiment, the number of the chuck structures 1 is set to one set, and a seal structure is provided adjacent to the chuck structure 1 in parallel. Specifically, the seal structure is provided inside the first bag sheet 1111 and is located below the male chuck 20, that is, it includes a seal rib 200 closer to the bottom of the bag 100 with a chuck with respect to the male chuck 20. Correspondingly, on the side of the second bag sheet 1112 facing the first bag sheet 1111, a seal groove 201 is provided that conforms to the shape of the seal rib 200 and can seal the internal space of the bag 100 with a chuck by closely adhering after the seal rib 200 is fitted therein.

[0056] It should be noted that the positions of the seal rib 200 and the seal groove 201 may be interchanged, that is, the seal rib 200 may be provided inside the second bag sheet 1112, and the seal groove 201 may be provided inside the first bag sheet 1111.

[0057] In some embodiments, the number of the seal rib 200 and the seal groove 201 may be two sets, three sets, etc., and the present application is not particularly limited.

[0058] Compared with the prior art, the chuck structure and the bag with a chuck of the present invention have the following advantages.

[0059] 1. The chuck structure in one embodiment of the present invention includes a corresponding male chuck and female chuck, which can be separated or fitted with each other. The chuck structure includes an alignment portion provided at both ends of the chuck structure and an engagement portion provided between the two alignment portions. The alignment portion includes a male alignment portion provided at both ends of the male chuck and a female alignment portion provided at both ends of the female chuck. A female alignment groove is formed in the female alignment portion, and at least a part of the male alignment portion is provided to intersect within the female alignment groove. The chuck structure includes an alignment portion and an engagement portion. The alignment portion is provided at both ends of the chuck structure, and the engagement portion is provided between the two alignment portions. The male chuck and the female chuck are engaged and connected by the engagement portion. On the other hand, the alignment portions located at both ends of the chuck structure are not engaged but are fitted by alignment, realizing an intersection structure where the male alignment portion and the female alignment portion are fitted, complementing the gap and strengthening the sealing performance of the chuck structure. The chuck structure has a better sealing effect, and the intersection structure also has a better operating feel during sealing.

[0060] 2. The engagement portion in one embodiment of the present invention includes a male engagement member provided on the male chuck, and the width of the male alignment portion is smaller than the width of the male engagement member. By setting the width of the male alignment portion to be smaller than the width of the male engagement member, the male alignment portion can relatively smoothly achieve alignment with the female alignment portion. The male engagement member reduces a part of the fitting thickness by engagement connection. Although the thickness of the male alignment portion and the male engagement member is the same, if the fitting thickness is not reduced by engagement connection, the male alignment portion will push the female alignment portion outwards, increasing and deforming the thickness of the end of the chuck structure, and gaps are likely to occur at the end of the chuck structure, reducing the sealing performance. Since the width of the male alignment portion is smaller than the thickness of the male engagement member, the male alignment portion can be fully accommodated in the female alignment portion, without the generation of a foreign body feeling and gaps caused by pushing the female alignment portion outwards, improving the sealing effect.

[0061] 3. In one embodiment of the present invention, the fastening part further includes a female fastener provided on the female zipper, the female fastener has a female fastening groove, the male fastener includes a root and a protrusion provided in order toward the female fastening groove, one end of the protrusion connected to the root is extended outward to form a fastening ridge, the width of the fastening ridge is greater than the width of the root, and the shape of the female fastening groove corresponds to the shape of the protrusion. With the above arrangement, the width of the extended and protruding fastening ridge is greater than the width of the root, so that it can be tightly engaged with the female fastening groove, which increases the difficulty of separating the male fastener and the female fastener during sealing and fitting, and further improves the sealing performance.

[0062] 4. In one embodiment of the present invention, the width of the male alignment part is smaller than the width of the root part, the exposed surface of one end of the root part close to the male alignment part is the step surface, the side of the root part close to the engagement ridge is the first step side, the side of the male alignment part close to the engagement ridge is the second step side, and the step surface, the first step side and the second step side constitute the step part. Since the width of the male alignment part is smaller than the width of the root part, there is an exposed surface of one end of the root part close to the male alignment part that does not contact the male alignment part, the exposed surface is the step surface, and the step surface, the first step side and the second step side constitute the step part. When the male zipper and the female zipper are mated, the step part acts as a barrier, preventing air in the male alignment part from flowing from the step part to the male fastener and further penetrating and destroying the sealing effect, effectively improving the sealing performance of the zipper structure.

[0063] 5. In one embodiment of the present invention, the female engaging groove is provided with an accommodating chamber corresponding to the engaging ridge, so that the accommodating chamber can accommodate the engaging ridge and abut against the engaging ridge, and the engaging ridge and the accommodating chamber form a tight engaging and fitting relationship, which improves the sealing performance and stability of the sealing structure.

[0064] 6. The chuck structure in one embodiment of the present invention is a silica gel chuck structure. The silica gel chuck structure adopts a silica gel material and has relatively excellent sealing performance. Moreover, it is non-toxic and odorless, and has the advantages of not causing pollution or odor transfer to contents such as food, being environmentally friendly and safe.

[0065] 7. In one embodiment of the present invention, one end close to the male engaging member of the male alignment portion is defined as the first end, and one end away from the male engaging member of the male alignment portion is defined as the second end. The distance from the first end to the second end is 3 mm or more and 12 mm or less. The distance from the first end to the second end is the length of the male alignment portion. 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 portion can be further accurately limited. The male alignment portion within the limited length range can improve the sealing performance and feel at the end of the chuck structure with relatively small dimensions.

[0066] 8. The bag with a chuck in one embodiment of the present invention includes a bag body and the above-mentioned chuck structure. The bag body includes a bag sheet. By sealing the bag sheet, a cavity and an opening communicating with the cavity are formed. The chuck structure is provided on one side of the inner surface of the bag sheet close to the opening. The bag with a chuck and the chuck structure have the same beneficial effects and will not be further described herein.

[0067] 9. The bag sheet in one embodiment of the present invention includes a first bag sheet provided with a male chuck and a second bag sheet provided with a female chuck, and a transfer material is provided at a connection location near the alignment portion of the first bag sheet and the second bag sheet. By providing the transfer material at a connection location near the alignment portion of the first bag sheet and the second bag sheet, the transfer material serves the role of transfer with respect to the plane where the first bag sheet and the second bag sheet are located, avoiding the situation where the first bag sheet and the second bag sheet simply come into direct contact at an acute angle, allowing the contact location to be transferred more gently, providing a larger accommodation space by the alignment material, preventing the alignment material from being pushed out due to insufficient accommodation space and causing a foreign body sensation, and further improving the operating feel when closing the chuck structure.

[0068] 10. The number of chuck structures in one embodiment of the present invention is one group or at least two groups. When the number of chuck structures is at least two groups, the multiple groups of chuck structures are provided adjacent to each other in parallel. By setting the number of chuck structures to one group, the bag with a chuck can achieve the opening and closing of sealed packaging by a single engaging portion, and the single engaging portion has a simple structure and relatively low cost. When setting the number of chuck structures to at least two groups, the multiple groups of chuck structures are provided adjacent to each other in parallel, the bag with a chuck can form multiple engaging portions, the multiple groups of chuck structures are provided adjacent to each other in parallel to form a multi-layer sealed packaging structure, and the sealing effect of the bag with a chuck is enhanced.

[0069] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit of the present invention shall all be included within the scope of the claims of this utility model registration.
