A highly protective foam bag includes: a protective device 1, a sealing strip 2, a separation device 3, and a fixing device 4;

[0027] The sealing strip 2 is disposed at one end of the protective device 1;

[0028] The separation device 3 includes a connecting belt 31, a plurality of separation grooves 32, a plurality of connecting blocks 33 and a pull belt 34. One side of the plurality of connecting blocks 33 is fixedly connected to the surface of the sealing belt 2. The connecting belt 31 is fixedly connected to one side of the connecting blocks 33. The plurality of separation grooves 32 are all opened inside the connecting belt 31. The pull belt 34 is disposed at one end of the connecting belt 31.

[0029] The fixing device 4 is disposed on one side of the sealing strip 2, and the fixing device 4 is used to limit the sealing strip 2.

[0030] The connecting strip 31 and the connecting block 33 are thinner than the sealing strip 2. Through the cooperation of multiple separation grooves 32 and multiple connecting blocks 33, the connecting block 33 can be easily separated from the sealing strip 2.

[0031] The fixing device 4 is a snap fastener, Velcro, zipper, etc., used to limit the distance between the sealing strip 2 and the protective device 1.

[0032] The fixing device 4 includes a first adhesive layer 41 and a first shielding layer 42. One side of the first adhesive layer 41 is fixedly installed on one side of the sealing strip 2, and the first shielding layer 42 is disposed on the surface of the first adhesive layer 41.

[0033] The first adhesive layer 41 is a double-sided adhesive, used to limit the distance between the sealing strip 2 and the protective device 1 after the first adhesive layer 41 is adhered to the surface of the protective device 1.

[0034] One side of each of the multiple connecting blocks 33 is fixedly connected to both sides of the connecting strip 31.

[0035] The sealing strip 2 is divided into two sections, and the other side of multiple connecting blocks 33 is fixedly connected to one side of the two sections of sealing strip 2, so as to connect the two sections of sealing strip 2 through the connecting strip 31 and the multiple connecting blocks 33, thereby facilitating the separation of the two sections of sealing strip 2 after the connecting strip 31 is pulled apart.

[0036] The working principle of the highly protective foam bag provided by this utility model is as follows:

[0037] In use, by pulling the pull strap 34 to one side, the connecting strap 31 is moved to one side, and after the multiple connecting blocks 33 are separated from the sealing strip 2, the sealing strip 2 can be divided into two sections.

[0038] Compared with related technologies, the protective foam bag provided by this utility model has the following beneficial effects:

[0039] This utility model provides a highly protective foam bag. The sealing strip 2 is divided into two sections by the separating device 3. After the sealing strip 2 is limited between the fixing device 4 and the protective device 1, the separating device 3 is separated, and the sealing strip 2 can be divided into sections. This makes it convenient to open one end of the protective device 1 for user convenience.

[0040] Second Embodiment

[0041] Please refer to the following: Figure 3 , Figure 4 and Figure 5 Based on the first embodiment of this application which provides a highly protective foam bag, the second embodiment of this application proposes another highly protective foam bag. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0042] Specifically, the second embodiment of this application provides a highly protective foam bag, which differs in that the highly protective foam bag has an inflation device 5 inside the sealing strip 2. The inflation device 5 includes an inflation chamber 51 and an inflation hole 52. The inflation chamber 51 is located inside the sealing strip 2, and the plurality of inflation holes 52 are all opened inside the sealing strip 2.

[0043] The air chamber 51 contains air, which is then delivered into the interior of the protective layer 61 when compressed.

[0044] The protective device 1 is provided with a protective component 6 inside. The protective component 6 includes a protective layer 61 and a plurality of vent holes 62. The plurality of protective layers 61 are all disposed inside the protective device 1, and the plurality of vent holes 62 are all opened inside the protective device 1.

[0045] The multiple protective layers 61 are connected by the multiple vent holes 62.

[0046] The protective layer 61 is an airbag that expands after gas enters the interior of the protective layer 61, thereby contacting the surface of the item inside the protective device 1 to provide better protection for the item.

[0047] The vent 62 is provided with a sealing device 7. The sealing device 7 includes a second adhesive layer 71 and a second shielding layer 72. One side of the second adhesive layer 71 is fixedly connected to one side of the inner wall of the vent 62, and the second shielding layer 72 is disposed on one side of the second adhesive layer 71.

[0048] The second adhesive layer 71 is a double-sided adhesive, used to seal the vent 62 after the second adhesive layer 71 and the second shielding layer 72 are bonded together. At the same time, when the inflation chamber 51 is squeezed, the internal gas pressure separates the second adhesive layer 71 and the second shielding layer 72, and the gas inside the inflation chamber 51 enters the interior of the protective layer 61 through the inflation hole 52.

[0049] The working principle of the highly protective foam bag provided by this utility model is as follows:

[0050] In use, after placing the item inside the protective device 1, the inflation chamber 51 is squeezed, and the gas pressure inside the inflation chamber 51 separates the second adhesive layer 71 from the second shielding layer 72. The gas inside the inflation chamber 51 enters the interior of the protective layer 61 through the inflation hole 52. The gas is then transported into the interior of the multiple protective layers 61 through the multiple ventilation holes 62, causing the multiple protective layers 61 to expand and come into contact with the surface of the item inside the protective device 1. This adheres the second adhesive layer 71 to the surface of the second shielding layer 72.

[0051] Compared with related technologies, the protective foam bag provided by this utility model has the following beneficial effects:

[0052] This utility model provides a highly protective foam bag. The protective component 6 is inflated by the inflation device 5, so that the protective component 6 comes into contact with the packaged item, thereby increasing the protective effect and limiting the position of the item.

[0053] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
