Description

Technical Field

[0001] The utility model relates to the technical field of facial mask bags, in particular to a dry-wet separation pull-ring double-cavity bag capable of secondary sealing. Background Art

[0002] High-end facial masks on the market require high packaging requirements, typically packaging the essence and mask cloth separately, using a dry-wet separation design. This approach ensures the quality and effectiveness of the mask. Separate packaging not only prevents the essence from affecting the mask cloth during long-term storage, but also allows users to flexibly pour the essence into the mask cloth during use.

[0003] For example, the prior art application number CN202311456061.4 relates to an aluminum foil positive-negative dry-wet separation pull-ring bag and its production process. The aluminum foil positive-negative dry-wet separation pull-ring bag comprises an opaque bag, a transparent bag, and an adhesive strip. The side of the opaque bag is fixedly connected to the side of the transparent bag. The side where the opaque bag connects to the transparent bag is provided with a first opening, and the side where the transparent bag connects to the opaque bag is provided with a corresponding second opening. The first and second openings are provided so that the interiors of the transparent and opaque bags are connected. Adhesive strips are provided at the first and second openings to temporarily separate the opaque and transparent bags. Pull rings are provided on both outer sides of the transparent bag.

[0004] Through actual use, the above scheme is known to achieve the effect of connecting the opaque bag and the transparent bag by mainly pulling the pull ring to separate the easy-to-remove PE layer, and finally allowing the liquid and the mask to contact and mix; however, during use, it was found that after the mask and the liquid were mixed, the bag body was not easy to be sealed again. If the mask is not used in time, the mask will have a short shelf life and is easy to enter dust, resulting in contamination and unhygienic use of the mask. For this reason, we have improved the above existing scheme based on actual usage. Utility Model Content

[0005] In view of the problem that after the facial mask is mixed with liquid, the bag is not easy to be sealed again. If the facial mask is not used in time, the shelf life of the facial mask will be short and dust will easily enter, resulting in contamination of the facial mask and unhygienic use. The utility model aims to provide a dry-wet separation pull-ring double-cavity bag that can be sealed twice.

[0006] To achieve this technical purpose, the solution of the utility model is: a dry-wet separation pull-ring double-cavity bag that can be sealed twice, comprising a bag body, a facial mask cavity and a material cavity are provided in the bag body, and handles for connecting the facial mask cavity and the material cavity are provided on the front and back surfaces of the bag body.

[0007] Furthermore, a hot pressing zone is provided in the longitudinal direction of the bag body for isolating the mask cavity and the material cavity. The hot pressing zone is composed of a straight heat sealing strip and a curved heat sealing strip. The straight heat sealing strip and the curved heat sealing strip are integrally hot-pressed and the straight heat sealing strip and the curved heat sealing strip are integrally arranged between the front and rear inner walls of the bag body for blocking the mask cavity and the material cavity.

[0008] Furthermore, handles are integrally provided on the front and rear surfaces of the bag body opposite to the curved heat sealing strip for pulling the bag body to separate the curved heat sealing strip from the bag body.

[0009] Furthermore, the plane side of the pressure strip is fixed to the front inner wall of the bag body by glue, and the rear inner wall of the bag body is fixed to the rear side of the cardboard by glue.

[0010] Furthermore, a groove is provided in the card plate, and the groove is arranged in an arc shape.

They are only for the purpose of clearly describing the present embodiment, and do not indicate or imply that the device or element referred to must have a specific orientation. Therefore, they should not be understood as limiting the present application.

[0021] like Figures 1 to 4 As shown, the embodiment of the present invention provides a double-chamber bag with a dry-wet separation pull ring that can be sealed twice, including a bag body 1, the bag body 1 is made of PE material, and is provided with a transparent mask cavity 4 and an opaque material cavity 5. The front and rear surfaces of the bag body 1 are provided with disposable PVC handles 3 for connecting the mask cavity 4 and the material cavity 5 to each other, and a 3mm tear notch 6 is provided on the left and right sides of the bag body 1. A sealing member 7 is provided in the bag body 1 below the tear notch 6 for re-sealing the bag body 1; the inner wall of the bag body 1 is made of PE-based easy-to-peel film layer, which can make the curved heat sealing strip 22 easy to tear open. After the curved heat sealing strip 22 is pulled open, the mask cavity 4 is connected with the material cavity 5, and the liquid in the material cavity 5 will enter the mask cavity 4 and mix with the mask;

[0022] refer to Figure 3 and Figure 4 The sealing member 7 comprises a soft rubber bead 71 and a hard rubber clip 72, which engage with each other to seal the bag 1. Handles 3 are integrally provided on the front and rear surfaces of the bag 1, opposite the curved heat-sealing strip 22. The flat side of the bead 71 is secured to the front inner wall of the bag 1 via adhesive, while the rear inner wall of the bag 1 is secured to the rear side of the clip 72 via adhesive. The clip 72 includes an arcuate groove 74. One side of the bead 71 is provided with an arc-shaped portion 73, and the arc-shaped portion 73 and the groove 74 are clamped to close the bead 71 and the card plate 72; after the facial mask is mixed with the liquid, the tearing opening 6 can be torn horizontally to tear the bag body 1 open and take out the facial mask for use. During use, if the facial mask needs to be placed back in the facial mask cavity 4 or is not in a hurry to use the facial mask, the bead 71 in the sealing member 7 can be pressed so that the arc-shaped portion 73 of the bead 71 is pressed into the groove 74 in the card plate 72. The width of the arc-shaped portion 73 is greater than the groove 74, and is greater than the range of 0.1mm-0.3mm, so that the groove 74 can be interference-connected to the bead 71, and the bead 71 and the card plate 72 can be closed;

[0023] refer to Figure 1 and Figure 2 The bag body 1 is longitudinally hot-pressed with a hot-pressing zone 2 for isolating the mask cavity 4 from the material cavity 5. The hot-pressing zone 2 is composed of a straight heat-sealing strip 21 and a curved heat-sealing strip 22. The straight heat-sealing strip 21 and the curved heat-sealing strip 22 are integrally hot-pressed and integrally arranged between the front and rear inner walls of the bag body 1. The outer surface of the bag body 1 opposite the mask cavity 4 is coated with a transparent layer 8 via an adhesive. The transparent layer 8 is a 0.1mm high-barrier SPET / SPE composite film that can withstand external pressure and has good permeability, allowing for full observation of the mixing of the mask and liquid. The outer surface of the bag body 1 opposite the material cavity 5 is coated with an opaque layer 9. The opaque layer 9 is made of a PET / AL / SPET / SPE composite material that can be used to block light and ensure the quality of the liquid in the material cavity 5. The heat sealing pressure of the straight heat sealing strip 21 is 0.2~0.9MPa, the heat sealing temperature is 200±22℃, and the heat sealing strength is 12±3N / 16mm; the hot pressing process of the curved heat sealing strip 22 is: heat sealing pressure 0.1~0.4MPa, heat sealing temperature 140±300℃, and heat sealing strength 5±2N / 12mm; the handle 3 is made of the opaque layer 9 on the outer surface of the material cavity 5, which is cut into a certain shape before compounding, and then compounded at the curved position of the curved heat sealing strip through positioning.

[0024] Working Principle: The inner wall of the bag body 1 of the present application is made of a PE-based easy-to-peel film layer, which makes the curved heat seal 22 easy to tear open. Therefore, the curved heat seal 22 can be pulled open by pulling the handle 3 without much force. After the curved heat seal 22 is pulled open, the mask cavity 4 is connected to the material cavity 5, and the liquid in the material cavity 5 will enter the mask cavity 4 and mix with the mask.

[0025] After the mask is mixed with the liquid, the tear 6 can be torn horizontally to tear the bag body 1 open, and the mask can be taken out for use. During use, if the mask needs to be placed back in the mask cavity 4 or is not in a hurry to use the mask, the pressure strip 71 in the sealing member 7 can be pressed so that the arc-shaped portion 73 of the pressure strip 71 is pressed into the groove 74 in the card plate 72 and is interference fit, so that the pressure strip 71 and the card plate 72 can be closed, so that the bag body 1 can be sealed again after being torn, which can ensure that the mask is not contaminated by dust and can be preserved for a long time.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
