Therefore, the directional terms used are for illustrative purposes and not for limiting the invention. Furthermore, unless otherwise specified, the term "connection" herein includes any direct or indirect structural connection means. Therefore, if the invention describes a first device connected to a second device, it means that the first device can be directly structurally connected to the second device, or indirectly structurally connected to the second device through other devices or connection means.

[0048] Please see Figures 1 to 3 As shown, Figure 1 This is a schematic diagram of the appearance of the storage bag 1A according to the first embodiment of the present invention. Figure 2 This is an exploded view of the components of the storage bag 1A according to the first embodiment of the present invention. Figure 3 This is a cross-sectional schematic diagram of the storage bag 1A according to the first embodiment of the present invention. Figures 1 to 3As shown, the present invention provides a storage bag 1A, comprising a bag body 11A, a snap fastener 12A, and a mating member 13A. The bag body 11A includes a first layer structure 111A and a second layer structure 112A connected to the first layer structure 111A. For example, the first layer structure 111A and the second layer structure 112A can be connected to each other by plastic welding technology (e.g., laser plastic welding, high-frequency plastic welding, ultrasonic plastic welding, or any other plastic welding technology). A receiving space 113A is formed between the first layer structure 111A and the second layer structure 112A. An opening 114A is formed on the first layer structure 111A that communicates with the receiving space 113A. A locking member 12A is arranged in the first layer structure 111A and continuously surrounds the periphery of the opening 114A. A mating member 13A is used to detachably engage with the locking member 12A. When the mating member 13A is engaged with the locking member 12A, the mating member 13A covers the opening 114A.

[0049] Preferably, the storage bag 1A further includes a one-way valve 14A, which is disposed in the bag body 11A and used to enable unidirectional flow of fluid (e.g., gas or liquid). In this embodiment, the one-way valve 14A can be connected to a negative pressure device (e.g., a negative pressure pump) and can discharge air and / or liquid from the storage space 113A by allowing air and / or liquid in the storage space 113A to flow out of the storage space 113A and preventing ambient air from entering the storage space 113A.

[0050] The one-way valve 14A may include a valve seat 141A and a sealing part 142A. The valve seat 141A may be integrally formed and connected to the first layer structure 111A of the bag body 11A by means of plastic welding technology (such as laser plastic welding, high frequency plastic welding, ultrasonic plastic welding or any other plastic welding technology). Therefore, the valve seat 141A can be regarded as part of the bag body 11A. The sealing part 142A may be provided on the valve seat 141A and is made of elastic material.

[0051] However, the present invention is not limited to this embodiment. For example, in another embodiment, the one-way valve may have a configuration for connecting to an air pump and for introducing ambient air into the housing by preventing air and / or liquid in the housing from flowing out of the housing and allowing ambient air to enter the housing.

[0052] Specifically, the engaging member 12A includes a base 121A, a first engaging portion 122A, and a second engaging portion 123A. For example, the base 121A of the engaging member 12A can be connected to the first layer structure 111A of the bag body 11A by means of plastic welding technology (such as laser plastic welding, high-frequency plastic welding, ultrasonic plastic welding, or any other plastic welding technology). The base 121A extends along the periphery of the opening 114A, the first engaging portion 122A protrudes from the base 121A and continuously surrounds the periphery of the opening 114A, and the second engaging portion 123A protrudes from the base 121A and continuously surrounds the first engaging portion 122A from the outside.

[0053] In this embodiment, the first engaging portion 122A can continuously surround the periphery of the opening 114A from the inside; however, the present invention is not limited to this embodiment. For example, in another embodiment, the first engaging portion can continuously surround the periphery of the opening from the outside as needed.

[0054] In this embodiment, the base 121A of the latching member 12A may be connected to the far side of the first layer structure 111A of the bag body 11A, away from the second layer structure 112A; however, the present invention is not limited to this embodiment. For example, in another embodiment, the base of the latching member may be located between and connected to the adjacent sides of the first and second layer structures of the bag body, depending on actual needs.

[0055] Furthermore, the mating part 13A includes a main body portion 131A, a first mating portion 132A and a second mating portion 133A. The first mating portion 132A protrudes from the main body portion 131A, and the second mating portion 133A protrudes from the main body portion 131A and continuously surrounds the first mating portion 132A from the outside.

[0056] Furthermore, the main body 131A includes a central region 1311A and a peripheral region 1312A. The peripheral region 1312A continuously surrounds the central region 1311A from the outside, and the first mating part 132A and the second mating part 133A protrude from the peripheral region 1312A of the main body 131A.

[0057] like Figure 3As shown, in this embodiment, to achieve a tight engagement between the engaging member 12A and the mating member 13A, the peripheral area 1312A of the main body 131A includes an abutting section S1A with a bevel. The middle area 1311A of the main body 131A includes an auxiliary section S2A. The cross-section of the auxiliary section S2A is V or U-shaped. When the mating member 13A engages with the engaging member 12A, that is, when the first engaging part 122A and the second engaging part 123A engage with the first mating part 132A and the second mating part 133A respectively, the first engaging part 122A is located between the first mating part 132A and the abutting section S1A and is engaged by the first mating part 132A and the abutting section S1A, and the second engaging part 123A is located between the first mating part 132A and the second mating part 133A and is engaged by the first mating part 132A and the second mating part 133A. On the other hand, when the mating part 13A engages with the engaging part 12A, the abutting section S1A can be at least partially inserted into a space RA defined by the first engaging part 122A, so that the two opposing parts (e.g., the two opposing wall parts) of the first engaging part 122A remain separated from each other.

[0058] Preferably, when the mating member 13A approaches the engaging member 12A along, for example, a first direction D1, so that the first engaging portion 122A and the second engaging portion 123A engage with the first mating portion 132A and the second mating portion 133A respectively, the inclined surface of the abutting section S1A can be used to push the first engaging portion 122A outward along, for example, a second direction D2, so that adjacent parts of the abutting section S1A, the first engaging portion 122A, the first mating portion 132A, the second engaging portion 123A, and the second mating portion 133A can be tightly engaged with each other. Furthermore, the direction from the open end to the closed end of the cross-section of the auxiliary section S2A is opposite to the protrusion direction of the first mating portion 132A relative to the main body portion 131A, and also opposite to the protrusion direction of the second mating portion 133A relative to the main body portion 131A. In other words, the direction from the open end to the closed end of the cross-section of the auxiliary section S2A is opposite to the first direction D1.

[0059] When the negative pressure device drives the air in the accommodating space 113A to be discharged through the one-way valve 14A, the auxiliary section S2A can elastically collapse along the first direction D1 under the action of the internal and external pressure difference between the storage bag 1A and the external environment, so as to push against the first engaging part 122A, the first mating part 132A, the second engaging part 123A and / or the second mating part 133A along the second direction D2, thereby eliminating the gap between adjacent parts of the abutting section S1A, the first engaging part 122A, the first mating part 132A, the second engaging part 123A and the second mating part 133A, and thus realizing the tight engagement of the engaging part 12A and the mating part 13A.

[0060] In this embodiment, the first engaging portion 122A, the second engaging portion 123A, the first mating portion 132A, and the second mating portion 133A may be hook-shaped, and the engaging member 12A and the mating member 13A may each be a single-piece structure made of elastic material. However, the present invention is not limited to this embodiment, and its implementation depends on actual needs. For example, in another embodiment, the first engaging portion, the second engaging portion, the first mating portion, and the second mating portion may be column-shaped, and the first mating portion and the second mating portion can be detachably installed on the main body.

[0061] Furthermore, in this embodiment, the engaging member 12A and the mating member 13A can both be straight structures; however, the present invention is not limited to this embodiment. For example, in another embodiment, the engaging member and the mating member can both be arc-shaped or U-shaped structures.

[0062] Understandably, in another embodiment, the second mating part and the second engaging part may be omitted as needed.

[0063] Please see Figure 4 and Figure 5 As shown, Figure 4 This is an exploded view of the components of storage bag 1B according to the second embodiment of the present invention. Figure 5 This is a cross-sectional schematic diagram of the storage bag 1B according to the second embodiment of the present invention. Figure 4 and Figure 5 As shown, unlike the first embodiment, in the second embodiment, a peripheral region 1312B of a main body portion 131B of a mating member 13B of the storage bag 1B includes an abutment section S1B, but a middle region 1311B of the main body portion 131B of the mating member 13B of the storage bag 1B does not include an auxiliary section. Other structural features of this embodiment are the same as those of the first embodiment, and for the sake of simplicity, will not be described further here.

Figure 9 This is a cross-sectional schematic diagram of the storage bag 1D according to the fourth embodiment of the present invention. Figure 8 and Figure 9 As shown, unlike the first embodiment, in the fourth embodiment, a peripheral region 1312D of a main body portion 131D of a mating member 13D of the storage bag 1D includes an abutment section S1D, but a middle region 1311D of the main body portion 131D of the mating member 13D of the storage bag 1D does not include an auxiliary section. Furthermore, a one-way valve 14D is disposed on a bag body 11D and centrally located near a locking member 12D and a mating member 13D, and the locking member 12D and the mating member 13D are both U-shaped structures. Other structural features of this embodiment are the same as in the first embodiment, and for simplicity, will not be described further here.

Figure 12 This is a cross-sectional schematic diagram of the storage bag 1E according to the fifth embodiment of the present invention. Figure 13 This is another cross-sectional schematic diagram of the storage bag 1E according to the fifth embodiment of the present invention. Figures 10 to 13 As shown, unlike the first embodiment, in the fifth embodiment, an opening 114E, a mating part 13E, and a locking part 12E are reshaped into a rectangle, and a one-way valve 14E is disposed on the mating part 13E and adjacent to one end of the mating part 13E. Specifically, the one-way valve 14E is disposed in an intermediate region 1311E of a main body 131E and located between two opposite parts of an auxiliary section S2E. The one-way valve 14E may include a valve seat 141E and a sealing part 142E. The valve seat 141E can be integrally formed on the mating part 13E by injection molding, so the valve seat 141E can be regarded as part of the mating part 13E. The sealing part 142E is disposed on the valve seat 141E and is made of an elastic material. Other structures in this embodiment are the same as in the first embodiment, and for the sake of simplicity, they will not be described again here.

For example, the snap-fit ​​member 12G and the mating member 13G can be integrally formed on the first layer structure 111G and the second layer structure 112G respectively by injection molding. The first layer structure 111G and the second layer structure 112G can be assembled with each other by the snap-fit ​​member 12G and the mating member 13G, and the first layer structure 111G and the second layer structure 112G can be separated from each other by the disengagement of the snap-fit ​​member 12G and the mating member 13G.

[0069] Furthermore, a one-way valve 14G is disposed on the bag body 11G. The one-way valve 14G may include a valve seat 141G and a sealing portion 142G. The valve seat 141G may be integrally formed on the second layer structure 112G, wherein the second layer structure 112G and the mating part 13G may be integrally formed together by injection molding. Therefore, the valve seat 141G can be regarded as part of the bag body 11G. The sealing portion 142G may be disposed on the valve seat 141G and made of elastic material. However, the present invention is not limited to this embodiment. For example, in another embodiment, the valve seat of the one-way valve may be integrally formed on the first layer structure, wherein the first layer structure and the engaging part may be integrally formed together by injection molding.

[0070] In addition, the engaging member 12G includes a base 121G, a first engaging portion 122G and a second engaging portion 123G. The base 121G extends along the periphery of the first layer structure 111G. The first engaging portion 122G protrudes from the base 121G and continuously surrounds the periphery of the first layer structure 111G. The second engaging portion 123G protrudes from the base 121G and continuously surrounds the first engaging portion 122G from the outside.

[0071] The mating part 13G includes a main body 131G, a first mating part 132G, and a second mating part 133G. The main body 131G includes a peripheral region 1312G, which is integrally formed to connect to the second layer structure 112G and continuously surrounds the periphery of the second layer structure 112G. The peripheral region 1312G includes an abutment section S1G with a bevel, which can be used to engage the mating part 13G with the engaging part 12G (for example, when the first engaging part 122G and the second engaging part 123G are engaged). When 3G is engaged with the first engaging part 132G and the second engaging part 133G respectively, it is at least partially inserted into the space defined by the first engaging part 122G, so that the two opposing parts of the first engaging part 122G remain separated from each other and are pushed outward against the first engaging part 122G. The first engaging part 132G protrudes from the peripheral area 1312G of the main body part 131G, and the second engaging part 133G protrudes from the peripheral area 1312G of the main body part 131G and continuously surrounds the first engaging part 132G from the outside. When the first engaging part 122G and the second engaging part 123G are engaged with the first mating part 132G and the second mating part 133G respectively, the first engaging part 122G is located between the first mating part 132G and the abutting section S1G and is engaged by the first mating part 132G and the abutting section S1G, and the second engaging part 123G is located between the first mating part 132G and the second mating part 133G and is engaged by the first mating part 132G and the second mating part 133G.

[0072] Additionally, the storage bag 1G includes at least one fastener 15G, which can be used to abut at least a portion of the mating part 13G and at least a portion of the locking part 12G to prevent at least a portion of the mating part 13G and at least a portion of the locking part 12G from separating from each other. The fastener 15G allows the mating part 13G and the locking part 12G to be at least partially separated from each other, thereby allowing the first layer structure 111G and the second layer structure 112G to be at least partially separated from each other, so as to facilitate the storage or retrieval of objects in the accommodating space. Understandably, the user can adjust the degree of separation between the first layer structure 111G and the second layer structure 112G by adjusting the position of the two fasteners 15G, and when the fastener 15G is removed, the mating part 13G and the locking part 12G can be completely separated, thereby allowing the first layer structure 111G and the second layer structure 112G to be completely separated for cleaning.

[0073] Similar to the aforementioned embodiments, the first engaging portion 122G, the second engaging portion 123G, the first mating portion 132G, and the second mating portion 133G are hook-shaped, and the engaging member 12G and the mating member 13G are single-piece structures made of elastic material.

[0074] Understandably, in another embodiment, the second mating part and the second engaging part may be omitted as needed.

[0075] Compared to existing technologies, in this invention, when the mating component engages with the engaging component, the engagement effectively prevents any leakage between the inside of the bag and the external environment, thus providing a better sealing effect. Furthermore, in this invention, the one-way valve can be installed on the bag body or the mating component according to actual needs, thus offering greater flexibility in appearance design to accommodate different applications.

[0076] The above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made in accordance with the present invention should fall within the scope of the present invention.
