Description

Technical Field

[0001] The utility model relates to the technical field of packaging, in particular to a mask packaging bag. Background Art

[0002] Packaging bags are bags used to package various items, often made of film materials. They facilitate transportation and storage during production and distribution. Masks are sanitary products, typically worn over the nose and mouth to filter air entering the mouth and nose, blocking harmful gases, odors, droplets, viruses, and other substances. Made of materials such as gauze or paper, masks have a certain filtering effect on air entering the lungs. Therefore, the mask packaging bags used to hold masks need to keep the internal mask storage space clean to prevent contamination.

[0003] Many mask packaging bags on the market use a bag body to hold multiple stacked masks. The bag opening is sealed with adhesive strips. After tearing off the adhesive strips and taking out the masks, the bag opening can be sealed again with adhesive strips. The advantage of this type of mask packaging bag is that the supply of masks is sufficient, which meets the needs of users and saves packaging materials.

[0004] However, when the mask taken out by the user needs to be temporarily stored or discarded after use, there are usually other unused masks in the mask packaging bag. In order to avoid contamination, the used mask cannot be put back in. This type of mask packaging bag also fails to provide other space for temporarily storing the used masks. Users may easily feel inconvenient to carry the used masks, and it is very likely that users will discard the masks at will, especially in outdoor environments. Utility Model Content

[0029] To make the objectives, technical solutions, and advantages of the present invention more apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. Examples of these preferred embodiments are illustrated in the accompanying drawings. The embodiments of the present invention shown in and described with reference to the accompanying drawings are merely exemplary, and the present invention is not limited to these embodiments.

[0030] In order to avoid obscuring the present invention due to unnecessary details, the drawings only show structures and / or processing steps closely related to the solutions according to the present invention, while other less relevant details are omitted.

[0031] It should also be noted that the actual film thickness of each structure in the following figures is extremely small. It is given a visible thickness here for clear display. When actually making mask packaging bags, the film thickness is selected according to the film material and process requirements. Figure 1 The transparent window 11 in the figure is represented by a dotted frame area, which means that it belongs to a structure that is blocked at the current viewing angle. Figure 2 and Figure 3 The wavy lines in the figure indicate that the extended structure has been omitted to highlight the area that needs to be shown.

[0032] like Figure 1As shown, an embodiment of the present invention provides a mask packaging bag, which includes a bag face 1 and a bag back 2. The side edges of the bag face 1 and the bag back 2 are adhered to each other by heat sealing, and the bottom edges of the bag face 1 and the bag back 2 are also adhered to each other by heat sealing, so that a mask accommodating space is enclosed between the bag face 1 and the bag back 2, and the interval between the top edge 2a of the bag back 2 and the bag face 1 constitutes a taking and placing opening 20 of the mask accommodating space. A covering film 3 is also extended from the top of the bag face 1, and the inner layer of the covering film 3 is provided with a pressure-sensitive adhesive strip 31. The covering film 3 can cover the bag back 2 to shield the taking and placing opening 20.

[0033] The back of the bag 2 is connected to a release film sub-bag 4, and one end of the release film sub-bag 4 is provided with a placement opening 40 for allowing the mask 5 to be placed into the release film sub-bag 4 through the placement opening 40. Figure 2 As shown, one side edge of the release film sub-bag 4 is connected to the bag back 2, so that the release film sub-bag 4 can be flipped around the bag back 2. After flipping upward, the release film sub-bag 4 can be peeled off and connected to the pressure-sensitive adhesive strip 31 of the covering film 3. The pressure-sensitive adhesive strip 31 is sealed to sandwich the release film sub-bag 4 between the covering film 3 and the bag back 2.

[0034] The usage principle of the above-mentioned mask packaging bag is as follows:

[0035] Combine Figure 2 As shown, before the mask 5 is packaged and stored in the finished mask packaging bag, the release film sub-bag 4 of the mask packaging bag is in an upward flipped state, the release film sub-bag 4 is overlapped on the surface of the bag back 2 near the access port 20, and the covering film 3 is then covered on the release film sub-bag 4. The release film sub-bag 4 is sandwiched between the covering film 3 and the bag back 2, and the pressure-sensitive adhesive strip 31 is sealed by the release film sub-bag 4 to prevent the pressure-sensitive adhesive strip 31 from contacting the covering film 3;

[0036] Combine Figure 3 As shown, when the mask packaging bag is used to package and store the masks 5, the release film sub-bag 4 can be torn off from the pressure-sensitive adhesive strip 31 of the cover film 3, and the release film sub-bag 4 can be turned down to expose the access opening 20. Multiple masks 5 can be loaded into the mask accommodating space between the bag face 1 and the bag back 2 through the access opening 20, and then the cover film 3 is covered on the bag back 2. The pressure-sensitive adhesive strip 31 is adhered to the bag back 2 to cover the access opening 20;

[0037] When it is necessary to take out the mask 5 from the mask storage space, tear the pressure-sensitive adhesive strip 31 from the bag back 2, flip up the covering film 3, take out the required mask 5 from the take-out opening 20, flip down the covering film 3 again to cover the bag back 2, and the pressure-sensitive adhesive strip 31 adheres to the bag back 2 to re-cover the take-out opening 20. After that, if the taken-out mask 5 needs to be temporarily stored and wait for disposal, the mask 5 can be folded first and then put into the release film sub-bag 4. Wait until a suitable disposal place such as a trash can is found, take the mask 5 out of the release film sub-bag 4 and discard it.

[0038] Thus, the release film sub-bag 4 can be used to temporarily store masks 5 that have been removed from the mask storage space, making it easier for users to carry the removed masks 5 without contaminating the unused masks 5 in the mask storage space, thereby improving the user experience. This helps prevent masks 5 from being discarded carelessly, protecting environmental hygiene. Furthermore, the release film sub-bag 4 is equivalent to a release film made into a bag body, connected to the bag back 2 and flipped over. It replaces the release paper or release film provided on the pressure-sensitive adhesive strip 31 of conventional mask packaging bags, and can also prevent the release paper or release film from being discarded carelessly after being torn off.

[0039] Specifically, the bag face 1 and the bag back 2 are both provided with printed patterns, and a non-printed pattern area is provided in the printed pattern of the bag face 1 to form a transparent window 11. The transparent window 11 is provided to facilitate the user to observe whether there are any masks 5 remaining in the mask storage space.

[0040] In this embodiment, the cover film sheet 3 overlaps the central area of the upwardly flipped release film sub-bag 4, ensuring that the pressure-sensitive adhesive strip 31 on the cover film sheet 3 does not extend beyond the coverage area of the flipped release film sub-bag 4. This prevents the pressure-sensitive adhesive strip 31 from being exposed and affecting its adhesive effect. The specific dimensions of the release film sub-bag 4 are freely selected based on actual needs such as production costs, the temporary storage space required for the masks, and the printing area, and are not limited here.

[0041] The covering film 3 is formed by folding the bag surface 1 and extending downward. The top edge of the covering film 3 is fixed to the bag surface 1 by heat sealing to form a fixed strip area 32, which is convenient for uncovering and turning over the covering film 3.

[0042] Furthermore, an anti-tear strip is provided at the fixed strip area 32 of the covering film 3 to prevent the user from using excessive force to open the packaging film 3 and damaging the covering film 3 and the bag surface 1. The material of the anti-tear strip can be the anti-tear film material commonly used in various packaging bags, so as to facilitate centralized and unified production processes.

[0043] In this embodiment, the bag face 1 and bag back 2 are formed by folding the same composite film. The composite film includes a polypropylene film layer and an aluminum film layer, but is not limited thereto. The composite film may also include other film layers that meet the requirements. The specific film layer configuration can be selected based on the performance requirements of the bag, such as waterproofing, puncture resistance, and high temperature resistance. In addition, the release film sub-bag 4 can be connected to the bag back by various methods, such as heat sealing, as long as the above requirements can be achieved.

[0044] A hanging hole 12 is provided on the bag surface 1, and the hanging hole 12 is located above the covering membrane 3. The hanging hole 12 is set as a circular hole in this embodiment. The setting of the hanging hole 12 can make the mask packaging bag hang on areas such as sales shelves. The hanging hole 12 can also be set to other shapes so that the user can also lift it with his hands, further improving the user experience.
