[0045] In the description of the present application, the terms "include", "have" indicate the existence of the described features, numbers, operations, elements and / or their combinations, but do not exclude the existence or addition of one or more other features, numbers, operations, elements and / or their combinations.
[0046] In the description of the present application, reference to "one embodiment" or "some embodiments" and the like means that a particular feature, structure or characteristic described in connection with the embodiment is included in one or more embodiments of the present application. Therefore, the statements "in one embodiment", "in some embodiments", "in other some embodiments", "in yet some embodiments" and the like appearing in different places in the specification are not necessarily all referring to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized.
[0047] Figures 1 to 5 A bagged desiccant provided by an embodiment of the present application is shown, which includes a desiccant 200 and a packaging bag 100 that encapsulates the desiccant 200, wherein the packaging bag 100 includes a first seal 10, a second seal 20, a third seal 30, and an identifier 40. Figure 1 And Figure 4 In Figure 5 , the desiccant 200 encapsulated in the packaging bag 100 is not visible due to the angle of view, but is shown schematically in
[0048] For the convenience of illustrating the present technology, a longitudinal direction DR1, a transverse direction DR2, and a depth direction DR3 that are perpendicular to each other are defined, in Figure 1 , the longitudinal direction DR1 is the up-down direction parallel to the plane of the paper, the transverse direction DR2 is the left-right direction parallel to the plane of the paper, and the depth direction DR3 is the inside-outside direction perpendicular to the plane of the paper.
[0049] The first seal 10 and the second seal 20 are spaced apart from each other in the longitudinal direction DR1 to respectively close opposite ends of the packaging bag 100 in the longitudinal direction DR1. Also, the first seal 10 and the second seal 20 are both seals extending in the transverse direction DR2 (both are substantially parallel), so they can also be referred to as transverse seals.
[0050] The third seal 30 extends in the longitudinal direction DR1 from the first seal 10 to the second seal 20 to close the portion of the packaging bag 100 between the first seal and the second seal 20. Since the third seal 30 is a seal extending in the longitudinal direction DR1, it can also be referred to as a longitudinal seal. Based on the longitudinal seal and the aforementioned two transverse seals, the packaging bag 100 defines a sealed packaging space 60, and the desiccant 200 is encapsulated in the packaging space 60. In some embodiments, the desiccant 200 can be canned into a semi-finished bag that has not yet been completely sealed after the processing of the longitudinal seal and one of the transverse seals is completed, and the processing of the other transverse seal is finally completed.
[0051] The identifier 40 is formed on the outer surface of the packaging bag 100 in a laser marking manner, and the identifier 40 is spaced apart from each of the first seal 10, the second seal 20, and the third seal 30, i.e., the position of the identifier 40 avoids the first seal 10, the second seal 20, and the third seal 30. In this way, the identifier 40 can be easily formed on the packaging bag 100 without using ink, which is safe and environmentally friendly, and the formed identifier 40 has good clarity.
[0052] The identifier 40 can be text and / or graphics, for example, a graphic for characterizing that the contents of the bag are not edible.
[0053] In some embodiments, the material forming the packaging bag 100 can be polyethylene to which a light-shielding agent is added, so that a clear identifier 40 can be easily formed thereon by laser marking.
[0054] See also Figure 1 and Figure 2 Each of the first and second edges 10 and 20 includes a first edge 1 and a second edge 2 that are laminated to each other in the depth direction DR3, although Figure 2 Although only the cross-sectional structure of the first edge 10 is shown, it should be understood that in the present embodiment, the second edge 20 has the same configuration as the first edge 10. The first edge 1 has a first face 11 and a second face 12 that are oppositely arranged in the depth direction DR3, and the second edge 2 has a third face 21 and a fourth face 22 that are oppositely arranged in the depth direction DR3, wherein the third face 21 and the second face 12 are laminatedly bonded to each other by an adhesive 50 provided therebetween. In other embodiments, the third face 21 and the second face 12 are thermally pressure-bonded, and the adhesive 50 is not used.
[0055] Further, the third face 21 is a non-smooth face having first meshed protrusions 23 and first meshed recesses 24 formed between the first meshed protrusions 23, and at least a portion of the adhesive 50 is filled and held in the first meshed recesses 24 and in contact with the second face 12. In this way, it is helpful to enhance the bonding strength of the third face 21 and the second face 12, and thereby the first edge 1 and the second edge 2, and further the structural stability of the first edge 10 and the second edge 20.
[0056] Further, the third face 21 is a non-smooth face having first meshed protrusions 23 and first meshed recesses 24 formed between the first meshed protrusions 23, and at least a portion of the adhesive 50 is filled and held in the first meshed recesses 24 and in contact with the second face 12. In this way, it is helpful to enhance the bonding strength of the third face 21 and the second face 12, and thereby the first edge 1 and the second edge 2, and further the structural stability of the first edge 10 and the second edge 20.
[0057] In the present embodiment, the first face 11 and the second face 12 are both smooth faces. In implementation, the second edge 2 can be pressed by a pressing member having meshed protrusions toward the first edge 1, so as to form the aforementioned second meshed recesses 26 and the aforementioned second meshed protrusions 25 on the fourth face 22, and to form the aforementioned first meshed protrusions 23 and the aforementioned first meshed recesses 24 on the third face 21. In addition, the aforementioned adhesive 50 can be a hot-melt adhesive.
[0058] In the present embodiment, the third edge 30 extends from the middle of the length of the first edge 10 to the middle of the length of the second edge 20, and thus the third edge 30 does not extend between the ends of the first edge 10 and the second edge 20.
[0059] See Figure 4 , the third edge 30 has a first end portion 30a included in the first edge 1 of the first edge 10, a second end portion 30b included in the first edge 1 of the second edge 20, and a main portion 30c extending from the first end portion 30a to the second end portion 30b. That is, the third edge 30 has a common portion with the first edge 1 of the first edge 10, and the third edge 30 has a common portion with the first edge 1 of the second edge 20.
[0060] The third edge 30 includes two third edges 3 stacked in the depth direction DR3 and defining the aforementioned first end portion 30a, the second end portion 30b, and the main portion 30c, one of the third edges 3 (corresponding Figure 5 to the third edge 3 on the lower side in the middle) defines the inner surface of the packaging bag 100, i.e., the packaging space 60 inside the packaging bag 100 is in contact with the third edge 3. In addition, the other third edge 3 (corresponding Figure 5 to the third edge 3 on the upper side in the middle) defines the outer surface of the packaging bag 100, which is in contact with the environment.
[0061] Furthermore, the aforementioned two third edges 3 are stacked on each other on the whole of the third edge 30, and the two third edges 3 are adhesively bonded by the adhesive 50 provided therebetween. Therefore, the portion of the first edge 1 common to the third edge 30 is a stacked structure.
[0062] More specifically, each third edge 3 has a fifth face 31 and a sixth face 32 disposed opposite each other in the depth direction DR3, and the adhesive 50 for bonding the two third edges 3 is sandwiched between the fifth face 31 of one of the third edges 3 and the sixth face 32 of the other third edge 3.
[0063] In Figure 5 , the part indicated by the mark 100 is the bag wall of the packaging bag 100 on the side opposite the third edge 30 in the depth direction DR3.
