[0047] In the following detailed description of the preferred embodiments, reference is made to the accompanying drawings which form a part hereof, and in which is shown by way of illustration specific embodiments in which the invention may be practiced. In this regard, directional terminology, such as “top”, “bottom”, “left”, “right”, “front”, “back”, etc., is used with reference to the orientation of the Figure(s) being described. The components of the present invention can be positioned in a number of different orientations. As such, the directional terminology is used for purposes of illustration and is in no way limiting. Accordingly, the drawings and descriptions will be regarded as illustrative in nature and not as restrictive. Also, if not specified, the term “connect” is intended to mean either an indirect or direct mechanical connection. Thus, if a first device is connected to a second device, that connection may be through a direct mechanical connection, or through an indirect mechanical connection via other devices and connections.

[0048] Please refer to FIG. 1 to FIG. 3. FIG. 1 is a schematic diagram of a storage bag 1A according to a first embodiment of the present invention. FIG. 2 is an exploded diagram of the storage bag 1A according to the first embodiment of the present invention. FIG. 3 is a sectional diagram of the storage bag 1A according to the first embodiment of the present invention. As shown in FIG. 1 to FIG. 3, the storage bag 1A includes a bag body 11A, an engaging component 12A and a cooperating component 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, such as laser plastic welding, high frequency plastic welding, ultrasonic plastic welding, or any other plastic welding technology. An accommodating 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 and communicated with the accommodating space 113A. The engaging component 12A is arranged on the first layer structure 111A and continuously surrounds a periphery of the opening 114A. The cooperating component 13A is configured to detachably engage with the engaging component 12A, and the opening 114A is covered by the cooperating component 13A when the engaging component 12A engages with the cooperating component 13A.

[0049] Preferably, the storage bag 1A further includes a one way valve 14A disposed on the bag body 11A and configured to allow fluid, such as gas or liquid, to flow in one direction only. In this embodiment, the one way valve 14A can be connected to a vacuum device, such as a vacuum pump, for discharging air and / or liquid inside the accommodating space 113A by allowing the air and / or liquid inside the accommodating space 113A to flow out of the accommodating space 113A and preventing ambient air from flowing into the accommodating space 113A.

[0050] The one way valve 14A can include a valve seat 141A and a sealing portion 142A. The valve seat 141A can be integrally connected to the first layer structure 111A by plastic welding technology, such as laser plastic welding, high frequency plastic welding, ultrasonic plastic welding, or any other plastic welding technology, and therefore the valve seat 141A can be considered as a part of the bag body. The sealing portion 142A can be fastened onto the valve seat 141A and made of an elastomeric material.

[0051] However, the present invention is not limited to this embodiment. For example, in another embodiment, the one way valve can have another structural configuration designed to be connected to an inflation pump for introducing the ambient air into the accommodating space by preventing the air and / or liquid inside the accommodating space from flowing out of the accommodating space and allow the ambient air to flow into the accommodating space.

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

[0053] In this embodiment, the first engaging portion 122A can surround the periphery of the opening 114A internally. However, the present invention is not limited to this embodiment. For example, in another embodiment, the first engaging portion can surround the periphery of the opening externally. It depends on practical demands.

[0054] In this embodiment, the base portion 121A of the engaging component 12A can be connected to a distal side of the first layer structure 111A away from the second layer structure 112A. However, the present invention is not limited to this embodiment. For example, in another embodiment, the base portion of the engaging component can be connected between two adjacent sides of the first layer structure and the second layer structure. It depends on practical demands.

[0055] Besides, the cooperating component 13A includes a main body portion 131A, a first cooperating portion 132A and a second cooperating portion 133A. The first cooperating portion 132A protrudes from the main body portion 131A. The second cooperating portion 133A protrudes from the main body portion 131A and continuously surrounds the first cooperating portion 132A externally.

[0056] Additionally, the main body portion 131A includes a middle part 1311A and a peripheral part 1312A continuously surrounding the middle part 1311A externally, and the first cooperating portion 132A and the second cooperating portion 133A protrude from the peripheral part 1312A of the main body portion 131A.

[0057] As shown in FIG. 3, in this embodiment, for achieving a tight engagement of the engaging component 12A and the cooperating component 13A, the peripheral part 1312A of the main body portion 131A includes an abutting segment S1A with an inclined surface, and the middle part 1311A of the main body portion 131A includes an auxiliary segment S2A with a cross section formed in a V-shape or a U-shape. When the cooperating component 13A is engaged with the engaging component 12A, i.e., when the first engaging portion 122A and the second engaging portion 123A engage with the first cooperating portion 132A and the second cooperating portion 133A, respectively, the first engaging portion 122A is located between and engaged by the first cooperating portion 132A and the abutting segment S1A, and the second engaging portion 123A is located between and engaged by the first cooperating portion 132A and the second cooperating portion 133A. In other words, the abutting segment S1A is configured to be at least partially inserted into a space RA enclosed by the first engaging portion 122A to keep two opposite sections, e.g., two opposite wall sections, of the first engaging portion 122A separated from each other when the cooperating component 13A is engaged with the engaging component 12A.

[0058] Preferably, when the cooperating component 13A is moved toward the engaging component 12A, e.g., along a first direction D1, to engage the first engaging portion 122A and the second engaging portion 123A with the first cooperating portion 132A and the second cooperating portion 133A, respectively, the abutting segment S1A is configured to push the first engaging portion 122A outwardly, e.g., along a second direction D2, by the inclined surface, so as to enable adjacent two of the abutting segment S1A, the first engaging portion 122A, the first cooperating portion 132A, the second engaging portion 123A and the second cooperating portion 133A to be tightly engaged with each other. Besides, a direction from an opening end of the cross section of the auxiliary segment S2A to a closed end of the cross section of the auxiliary segment S2A is opposite to a protruding direction of the first cooperating portion 132A from the main body portion 131A and an protruding direction of the second cooperating portion 133A from the main body portion 131A. In other words, the direction from an opening end of the cross section of the auxiliary segment S2A to a closed end of the cross section of the auxiliary segment S2A is opposite to the first direction D1.

[0059] When air inside the accommodating space 113A is discharged through the one way valve 14A by the vacuum device, the auxiliary segment S2A can be resiliently collapsed along the first direction D1 by a differential pressure between an internal pressure of the storage bag 1A and an environmental pressure to push the first engaging portion 122A, the first cooperating portion 132A, the second engaging portion 123A and / or the second cooperating portion 133A along the second direction D2 to eliminate any gap between adjacent two of the abutting segment S1A, the first engaging portion 122A, the first cooperating portion 132A, the second engaging portion 123A and / or the second cooperating portion 133A, thereby achieving tight engagement of the engaging component 12A and the cooperating component 13A when the air inside the accommodating space 113A is discharged.

[0060] In this embodiment, the first engaging portion 122A, the second engaging portion 123A, the first cooperating portion 132A and the second cooperating portion 133A are formed in hook-shapes, and each of the engaging component 12A and the cooperating component 13A is a one-piece structure made of elastomeric material. However, the present invention is not limited to this embodiment. It depends on practical demands. For example, in another embodiment, the first engaging portion, the second engaging portion, the first cooperating portion and the second cooperating portion can be formed in column-shapes, and the first cooperating portion and the second cooperating portion can be detachably mounted on the main body portion.

[0061] Besides, in this embodiment, each of the engaging component 12A and the cooperating component 13A is a straight structure. However, the present invention is not limited to this embodiment. It depends on practical demands. For example, in another embodiment, each of the engaging component and the cooperating component can be a curved structure or a U-shaped structure.

[0062] Understandably, in another embodiment, the second cooperating portion and the second engaging portion can be omitted according to practical demands.

[0072] Besides, the storage bag 1G further includes at least one clip component 15G to abut against at least one portion of the cooperating component 13G and at least one portion of the engaging component 12G for preventing separation of the at least one portion of the cooperating component 13G and the at least one portion of the engaging component 12G. By the at least one clip component 15G, the cooperating component 13G is allowed to be partially disengaged from the engaging component 12G to partially separate the first layer structure 111G and the second layer structure 112G from each other for easy storage. Understandably, the two clip components 15G can be used to control a degree of separation of the first layer structure 111G from the second layer structure 112G by moving to different positions. The cooperating component 13G is allowed to be completely disengaged from the engaging component 12G to completely separate the first layer structure 111G and the second layer structure 112G from each other for easy cleaning after the at least one clip component 15G is removed.

[0073] Similar to the aforementioned embodiments, the first engaging portion 122G, the second engaging portion 123G, the first cooperating portion 132G and the second cooperating portion 133G are formed in hook-shapes, and each of the engaging component 12G and the cooperating component 13G is a one-piece structure made of elastomeric material.

[0074] Understandably, in another embodiment, the second cooperating portion and the second engaging portion can be omitted according to practical demands.

[0075] In contrast to the prior art, in the present invention, when the cooperating component engages with the engaging component, an engagement of the cooperating component and the engaging component effectively prevents any leakage between an interior of the bag body and an external environment. Therefore, the present invention provides an improved sealing effect. Besides, the one way valve can be configured to be disposed on the bag body or the cooperating component according to practical demands. Therefore, the present invention also offers flexibility in appearance to meet different requirements.

[0076] Those skilled in the art will readily observe that numerous modifications and alterations of the device and method may be made while retaining the teachings of the invention. Accordingly, the above disclosure should be construed as limited only by the metes and bounds of the appended claims.

[0047] In the following detailed description of the preferred embodiments, reference is made to the accompanying drawings which form a part hereof, and in which is shown by way of illustration specific embodiments in which the invention may be practiced. In this regard, directional terminology, such as “top”, “bottom”, “left”, “right”, “front”, “back”, etc., is used with reference to the orientation of the Figure(s) being described. The components of the present invention can be positioned in a number of different orientations. As such, the directional terminology is used for purposes of illustration and is in no way limiting. Accordingly, the drawings and descriptions will be regarded as illustrative in nature and not as restrictive. Also, if not specified, the term “connect” is intended to mean either an indirect or direct mechanical connection. Thus, if a first device is connected to a second device, that connection may be through a direct mechanical connection, or through an indirect mechanical connection via other devices and connections.

[0048] Please refer to FIG. 1 to FIG. 3. FIG. 1 is a schematic diagram of a storage bag 1A according to a first embodiment of the present invention. FIG. 2 is an exploded diagram of the storage bag 1A according to the first embodiment of the present invention. FIG. 3 is a sectional diagram of the storage bag 1A according to the first embodiment of the present invention. As shown in FIG. 1 to FIG. 3, the storage bag 1A includes a bag body 11A, an engaging component 12A and a cooperating component 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, such as laser plastic welding, high frequency plastic welding, ultrasonic plastic welding, or any other plastic welding technology. An accommodating 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 and communicated with the accommodating space 113A. The engaging component 12A is arranged on the first layer structure 111A and continuously surrounds a periphery of the opening 114A. The cooperating component 13A is configured to detachably engage with the engaging component 12A, and the opening 114A is covered by the cooperating component 13A when the engaging component 12A engages with the cooperating component 13A.

[0049] Preferably, the storage bag 1A further includes a one way valve 14A disposed on the bag body 11A and configured to allow fluid, such as gas or liquid, to flow in one direction only. In this embodiment, the one way valve 14A can be connected to a vacuum device, such as a vacuum pump, for discharging air and / or liquid inside the accommodating space 113A by allowing the air and / or liquid inside the accommodating space 113A to flow out of the accommodating space 113A and preventing ambient air from flowing into the accommodating space 113A.

[0050] The one way valve 14A can include a valve seat 141A and a sealing portion 142A. The valve seat 141A can be integrally connected to the first layer structure 111A by plastic welding technology, such as laser plastic welding, high frequency plastic welding, ultrasonic plastic welding, or any other plastic welding technology, and therefore the valve seat 141A can be considered as a part of the bag body. The sealing portion 142A can be fastened onto the valve seat 141A and made of an elastomeric material.

[0051] However, the present invention is not limited to this embodiment. For example, in another embodiment, the one way valve can have another structural configuration designed to be connected to an inflation pump for introducing the ambient air into the accommodating space by preventing the air and / or liquid inside the accommodating space from flowing out of the accommodating space and allow the ambient air to flow into the accommodating space.

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

[0053] In this embodiment, the first engaging portion 122A can surround the periphery of the opening 114A internally. However, the present invention is not limited to this embodiment. For example, in another embodiment, the first engaging portion can surround the periphery of the opening externally. It depends on practical demands.

[0054] In this embodiment, the base portion 121A of the engaging component 12A can be connected to a distal side of the first layer structure 111A away from the second layer structure 112A. However, the present invention is not limited to this embodiment. For example, in another embodiment, the base portion of the engaging component can be connected between two adjacent sides of the first layer structure and the second layer structure. It depends on practical demands.

[0055] Besides, the cooperating component 13A includes a main body portion 131A, a first cooperating portion 132A and a second cooperating portion 133A. The first cooperating portion 132A protrudes from the main body portion 131A. The second cooperating portion 133A protrudes from the main body portion 131A and continuously surrounds the first cooperating portion 132A externally.

[0056] Additionally, the main body portion 131A includes a middle part 1311A and a peripheral part 1312A continuously surrounding the middle part 1311A externally, and the first cooperating portion 132A and the second cooperating portion 133A protrude from the peripheral part 1312A of the main body portion 131A.

[0057] As shown in FIG. 3, in this embodiment, for achieving a tight engagement of the engaging component 12A and the cooperating component 13A, the peripheral part 1312A of the main body portion 131A includes an abutting segment S1A with an inclined surface, and the middle part 1311A of the main body portion 131A includes an auxiliary segment S2A with a cross section formed in a V-shape or a U-shape. When the cooperating component 13A is engaged with the engaging component 12A, i.e., when the first engaging portion 122A and the second engaging portion 123A engage with the first cooperating portion 132A and the second cooperating portion 133A, respectively, the first engaging portion 122A is located between and engaged by the first cooperating portion 132A and the abutting segment S1A, and the second engaging portion 123A is located between and engaged by the first cooperating portion 132A and the second cooperating portion 133A. In other words, the abutting segment S1A is configured to be at least partially inserted into a space RA enclosed by the first engaging portion 122A to keep two opposite sections, e.g., two opposite wall sections, of the first engaging portion 122A separated from each other when the cooperating component 13A is engaged with the engaging component 12A.

[0058] Preferably, when the cooperating component 13A is moved toward the engaging component 12A, e.g., along a first direction D1, to engage the first engaging portion 122A and the second engaging portion 123A with the first cooperating portion 132A and the second cooperating portion 133A, respectively, the abutting segment S1A is configured to push the first engaging portion 122A outwardly, e.g., along a second direction D2, by the inclined surface, so as to enable adjacent two of the abutting segment S1A, the first engaging portion 122A, the first cooperating portion 132A, the second engaging portion 123A and the second cooperating portion 133A to be tightly engaged with each other. Besides, a direction from an opening end of the cross section of the auxiliary segment S2A to a closed end of the cross section of the auxiliary segment S2A is opposite to a protruding direction of the first cooperating portion 132A from the main body portion 131A and an protruding direction of the second cooperating portion 133A from the main body portion 131A. In other words, the direction from an opening end of the cross section of the auxiliary segment S2A to a closed end of the cross section of the auxiliary segment S2A is opposite to the first direction D1.

[0059] When air inside the accommodating space 113A is discharged through the one way valve 14A by the vacuum device, the auxiliary segment S2A can be resiliently collapsed along the first direction D1 by a differential pressure between an internal pressure of the storage bag 1A and an environmental pressure to push the first engaging portion 122A, the first cooperating portion 132A, the second engaging portion 123A and / or the second cooperating portion 133A along the second direction D2 to eliminate any gap between adjacent two of the abutting segment S1A, the first engaging portion 122A, the first cooperating portion 132A, the second engaging portion 123A and / or the second cooperating portion 133A, thereby achieving tight engagement of the engaging component 12A and the cooperating component 13A when the air inside the accommodating space 113A is discharged.

[0060] In this embodiment, the first engaging portion 122A, the second engaging portion 123A, the first cooperating portion 132A and the second cooperating portion 133A are formed in hook-shapes, and each of the engaging component 12A and the cooperating component 13A is a one-piece structure made of elastomeric material. However, the present invention is not limited to this embodiment. It depends on practical demands. For example, in another embodiment, the first engaging portion, the second engaging portion, the first cooperating portion and the second cooperating portion can be formed in column-shapes, and the first cooperating portion and the second cooperating portion can be detachably mounted on the main body portion.

[0061] Besides, in this embodiment, each of the engaging component 12A and the cooperating component 13A is a straight structure. However, the present invention is not limited to this embodiment. It depends on practical demands. For example, in another embodiment, each of the engaging component and the cooperating component can be a curved structure or a U-shaped structure.

[0062] Understandably, in another embodiment, the second cooperating portion and the second engaging portion can be omitted according to practical demands.

The valve seat 14G can be integrally formed with the second layer structure 112G which the cooperating component 13G is integrally formed with by injection molding, and therefore the valve seat 141G can be considered as a part of the bag body 11G. The sealing portion 142G can be fastened onto the valve seat 141G and made of an elastomeric material. However, the present invention is not limited to this embodiment, the valve seat of the one way valve can be integrally formed with the first layer structure which the engaging component is integrally formed with by injection molding.

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

[0071] The cooperating component 13G includes a main body portion 131G, a first cooperating portion 132G and a second cooperating portion 133G. The main body portion 131G includes a peripheral part 1312G integrally connected to the second layer structure 112G and continuously surrounding the periphery of the second layer structure 112G. The peripheral part 1312G includes an abutting segment S1G with an inclined surface configured to be at least partially inserted into a space enclosed by the first engaging portion 122G to keep two opposite wall sections of the first engaging portion 122G separated from each other and push the first engaging portion 122G outwardly when the cooperating component 13G is engaged with the engaging component 12G, i.e., when the first engaging portion 122G and the second engaging portion 123G engage with the first cooperating portion 132G and the second cooperating portion 133G, respectively. The first cooperating portion 132G protrudes from the peripheral part 1312G of the main body portion 131G. The second cooperating portion 133G protrudes from the peripheral part 1312G of the main body portion 131G and continuously surrounds the first cooperating portion 132G externally. When the first engaging portion 122G and the second engaging portion 123G engage with the first cooperating portion 132G and the second cooperating portion 133G, respectively, the first engaging portion 122G is located between and engaged by the first cooperating portion 132G and the abutting segment S1G, and the second engaging portion 123G is located between and engaged by the first cooperating portion 132G and the second cooperating portion 133G.

[0072] Besides, the storage bag 1G further includes at least one clip component 15G to abut against at least one portion of the cooperating component 13G and at least one portion of the engaging component 12G for preventing separation of the at least one portion of the cooperating component 13G and the at least one portion of the engaging component 12G. By the at least one clip component 15G, the cooperating component 13G is allowed to be partially disengaged from the engaging component 12G to partially separate the first layer structure 111G and the second layer structure 112G from each other for easy storage. Understandably, the two clip components 15G can be used to control a degree of separation of the first layer structure 111G from the second layer structure 112G by moving to different positions. The cooperating component 13G is allowed to be completely disengaged from the engaging component 12G to completely separate the first layer structure 111G and the second layer structure 112G from each other for easy cleaning after the at least one clip component 15G is removed.

[0073] Similar to the aforementioned embodiments, the first engaging portion 122G, the second engaging portion 123G, the first cooperating portion 132G and the second cooperating portion 133G are formed in hook-shapes, and each of the engaging component 12G and the cooperating component 13G is a one-piece structure made of elastomeric material.

[0074] Understandably, in another embodiment, the second cooperating portion and the second engaging portion can be omitted according to practical demands.

[0075] In contrast to the prior art, in the present invention, when the cooperating component engages with the engaging component, an engagement of the cooperating component and the engaging component effectively prevents any leakage between an interior of the bag body and an external environment. Therefore, the present invention provides an improved sealing effect. Besides, the one way valve can be configured to be disposed on the bag body or the cooperating component according to practical demands. Therefore, the present invention also offers flexibility in appearance to meet different requirements.

[0076] Those skilled in the art will readily observe that numerous modifications and alterations of the device and method may be made while retaining the teachings of the invention. Accordingly, the above disclosure should be construed as limited only by the metes and bounds of the appended claims.
