Part of the easy-to-tear mask remains intact.

Please refer to Figure 1 and Figure 2 first. A first embodiment of the present invention proposes a container 10 and a tear-away film 20. The container 10 has a cover 11 and a receiving body 12. The receiving body 12 forms an opening, and the cover 11 is detachably covered in the opening.

The easy-to-tap sleeve 20 is sleeve-shaped and sleeved and attached to the outer wall surface of the container 10. The heat-shrinkable film can be made of PolyVinyl Chloride (PVC) or Oriented Polystyrene (PolyVinyl Chloride, PVC). OPS), Polyethylene Terephthalate (PET), Polymer Optical Fiber (POF) or Oriented Polypropylene (OPP). The easy tear film 20 has a transverse crack 21 in the shape of a broken line, a first oblique crack 22, a second oblique crack 23, a third oblique crack 24, and a fourth oblique crack 25. The so-called dotted line means that the cracks are formed with a plurality of small slits which are arranged in a line and are arranged in a line, and in the embodiment, the small slits can be cut by the dashed knife or the laser cutting or the like in the easy tearing film 20 form.

The transverse crack 21 is parallel to the top edge of the sleeve 20 and is surrounded by a circumference and is located below the container 11 with the lid 11.

The first oblique slit 22 extends obliquely downward from the top edge of the easy tear film 20, and the direction of the inclination may be clockwise or counterclockwise. The first oblique crack 22 may be an oblique straight line or a concave curved shape. The lower end of the first oblique crack 22 is connected to the lateral slit 21. Specifically, the lower end of the first oblique crack 22 is parallel to the transverse crack 21 and is connected to the transverse crack 21 in a smooth curve. The second oblique crack 23 also extends obliquely downward from the top edge of the mantle, and the second oblique crack 23 is spaced apart from the first oblique crack 22. The first oblique crack 22 corresponds to the oblique direction of the second oblique crack 23, that is, the same as the clockwise tilt or the same counterclockwise tilt, and the first oblique crack 22 and the second oblique crack 23 may further have The same slope or curvature. In the present embodiment, the lower end of the second oblique crack 23 is also connected to the lateral slit 21, but not limited thereto. In other words, the length of the second oblique crack 23 may be shorter than the length of the first oblique crack 22. The first oblique crack 22 and the second oblique crack 23 are attached to the side wall surface of the cover 11 , so that the angle at which the first oblique crack 22 and the second oblique crack 23 are inclined can be designed to match the size of the cover 11 .
