The first easy-to-peel strip and the second easy-to-peel strip are arranged in central symmetry, which ensures that the bag body is uniformly stressed and avoids local rupture caused by stress concentration. The cooperation of the clamping block and the connecting groove ensures the adhesion strength of the easy-to-peel strip and provides a clear force point for the user, facilitating the connection of the two cavities. The dislocation of the first rib and the second rib can be combined with the external identification of the bag body to intuitively guide the user to open the easy-to-peel strip in the correct direction, improving the convenience of use.

DETAILED DESCRIPTION

[0025] The specific embodiments of the utility model are further described below in combination with the drawings and examples. The following examples are only used to more clearly illustrate the technical scheme of the utility model, and cannot limit the protection scope of the utility model.

[0026] Example 1

[0027] The separate type mask bag of the embodiment includes bag body 1, and the inside of bag body 1 is divided into liquid cavity 2 and mask cavity 3 through vertical separation structure. The essence liquid is encapsulated in liquid cavity 2, and the dry film cloth is encapsulated in mask cavity 3. The separation structure is composed of first easy-to-uncover strip 4 and second easy-to-uncover strip 5 which are symmetrically arranged on the two sides of the inside of bag body 1, and the two easy-to-uncover strips are separable and adhered through low-temperature hot melt adhesive 6.

[0028] Bag body 1 is made of polyethylene composite film through three-edge heat sealing, and the composite film is sequentially composed of barrier layer 13, ink layer 14, glue layer 15 and heat sealing layer 16 from outside to inside. Barrier layer 13 selects longitudinal stretch polyethylene film LDPE, heat sealing layer 16 adopts high-density polyethylene film HDPE, and glue layer 15 is double-component polyurethane glue. First easy-to-uncover strip 4 and second easy-to-uncover strip 5 are fused on heat sealing layer 16 through hot pressing process, and a sealed barrier is formed when the two are adhered.

[0029] When in use, the user extrudes first rib 11 and second rib 12 on the outside of bag body 1, uses the height difference of the dislocation to guide the force direction, makes first easy-to-uncover strip 4 and second easy-to-uncover strip 5 separate along hot melt adhesive 6, the essence liquid of liquid cavity 2 flows into mask cavity 3 and infiltrates the film cloth, and instant activation is realized.

[0030] Example 2:

[0031] On the basis of example 1, transverse embossing 7 is arranged on the surface of first easy-to-uncover strip 4 and second easy-to-uncover strip 5, and the depth of embossing is 0.1-0.3mm, so as to increase the contact area of hot melt adhesive 6. Transverse embossing 7 extends to vertical embossing 8 at both ends, and vertical embossing 8 is embedded into the heat sealing edge of the outer periphery of bag body 1 to form a locking edge, preventing the embossing area from tearing when separating.

[0032] When the composite film is prepared, the surfaces of the easy-to-peel strips are provided with transverse embossing 7, and the vertical embossing 8 is aligned with the heat sealing line of the side edge of the bag body 1 during heat sealing bagging, so as to ensure that the locking edge is sealingly combined with the bag body 1. This design improves the bonding strength of the easy-to-peel strips while avoiding cross contamination between the liquid cavity 2 and the mask cavity 3.

[0033] Embodiment 3:

[0034] In this embodiment, the top surface of the first easy-to-peel strip 4 is provided with a trapezoidal clamping block 9, and the top surface of the second easy-to-peel strip 5 is provided with a matching connecting groove 10, and the clamping block 9 and the connecting groove 10 are arranged in a central symmetry. The first rib 11 and the second rib 12 are arranged on the outer side of the bag body 1 corresponding to the position of the easy-to-peel strip, and the two are longitudinally staggered by 3-5 mm, and the height of the first rib 11 is higher than that of the second rib 12.

[0035] When the user presses the first rib 11 and the second rib 12, the clamping block 9 is sheared out of the connecting groove 10, guiding the easy-to-peel strip to separate and open along the radial direction of the hot melt adhesive 6. The staggered rib design is combined with the arrow mark that can be arranged on the outside of the bag body 1 to form an intuitive operation guide. The clamping block can be an elastic component that is connected to the connecting groove by deformation.

[0036] Embodiment 4:

[0037] On the basis of any structure of embodiments 1-3, the barrier layer 13 is replaced by an ethylene-vinyl alcohol copolymer EVOH film, the heat sealing layer 16 is made of biodegradable high-density polyethylene Bio-HDPE, and the glue layer 15 is selected from a solvent-free glue. The ink layer 14 is printed on the inner surface of the barrier layer 13 by polyurethane ink, and the pattern area avoids the easy-to-peel strip bonding part.

[0038] In this embodiment, the materials of each layer of the bag body 1 are all polyethylene base materials, which can be directly crushed and granulated for recycling, with a recycling rate of more than 95%, and the oxygen transmission rate of the EVOH barrier layer 13 is less than 1 cm³ / (m²·24h·atm), and the water vapor transmission rate is less than 2 g / (m²·24h·atm), which significantly prolongs the shelf life of the essence.

[0039] Among them, the hot melt adhesive of each embodiment preferably uses low-temperature hot melt adhesive below 130°C, such as Boshibond LT-130, Surebonder LK-100, 3M Scotch-Weld™ 3748, AdTech 500-01, etc. Removable glue.

[0040] The above only describes the preferred embodiments of the present application, and it should be pointed out that for ordinary skilled persons in the technical field, without departing from the technical principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements should also be considered as the protection range of the present application.
