[0001] The utility model belongs to the technical field of vacuum bags, in particular to a vacuum sealing bag. Background Art

[0002] As an efficient and convenient packaging solution, vacuum sealed bags have been widely used in many fields such as food, medicine, and electronic products. However, existing vacuum sealed bags have some limitations in design and function, especially in the setting of air valves and the optimization of inner wall structure.

[0003] Existing vacuum sealing bags usually rely on external equipment for operation during the vacuuming and inflation process, and lack a convenient air valve design. This leads to a complicated and inefficient operation process and increases the cost of use. At the same time, during long-term storage or transportation, the sealing performance may be affected due to changes in the pressure inside the bag, resulting in a decrease in the quality of the contents. At the same time, the inner wall of existing vacuum sealing bags is usually relatively smooth, resulting in the difficulty in completely discharging the residual air in the bag during the vacuuming process, affecting the sealing effect. At the same time, the smooth inner wall also easily causes the contents to slide inside the bag, reducing the stability of the packaging.

[0004] Therefore, the inventor is committed to designing a vacuum sealing bag to solve the above problems. Utility Model Content

The logo 112 is elliptical, and the edge of the logo 112 is coated with color to facilitate users to find the specific location of the logo 112. The logo 112 has a date column and a name column to facilitate recording the time of vacuuming the sealed bag and the name of the contents. The pattern 111 can be animals (such as cats), plants and other graphics.

[0030] Reference Figure 1 and Figure 3 The second film layer 12 constitutes the reverse side of the bag body 1. The second film layer 12 is made of plastic material and is square in shape. A plurality of grooves 122 are arranged on the outer wall of the second film layer 12. The plurality of grooves 122 correspond to the plurality of protrusions 121 one by one, that is, the plurality of protrusions 121 are formed by the side wall of the second film layer 12 being sunken from the outside to the inside in the form of a plurality of grooves 122. The edges of the second film layer 12 and the first film layer 11 (i.e., the left and right edges and the lower edge) are hot pressed to form a U-shaped side pressure line 2, so that a seal is formed at the upper end of the entire bag body 1.

[0031] Reference Figure 1 and Figure 4 The sealing zipper 3 is located in the seal of the bag body 1. The sealing zipper 3 is specifically a bite-in double-layer zipper. Specifically, the sealing zipper 3 includes a first zipper body 31 and a second zipper body 32. The first zipper body 31 is connected to the inner wall of the first film layer 11 by heat pressing. The first zipper body 31 is vertically spaced and convexly provided with a first bite tooth 311 and two first protrusions 312 on the bite side. The two first protrusions 312 are spaced to form a first bite groove. The second zipper body 32 is connected to the inner wall of the second zipper body 32 by heat pressing. The bite side of the second zipper body 32 is vertically spaced and convexly provided with a first bite tooth 311 and two first protrusions 312. The two first protrusions 312 are spaced to form a first bite groove. A second engaging tooth 321 and two second protrusions 322 are protruded toward the interval, and the two second protrusions 322 are spaced apart to form a second engaging groove. Both ends of the first zipper body 31 and the second zipper body 32 are connected to the side pressure line 2. When the user manually presses the first zipper body 31 and the second zipper body 32, the first engaging tooth 311 on the first film layer 11 engages with the second engaging groove on the second film layer 12. At the same time, the second engaging tooth 321 on the second film layer 12 engages with the first engaging groove of the first film layer 11, so that the sealing portion of the bag body 1 is sealed.

[0032] Reference Figure 1 , Figure 5 , Figure 6 and Figure 7The air valve 4 is flat and round as a whole. The air valve 4 includes a valve body 41, a prompt layer 42 and a covering film 43. The covering film 43, the prompt layer 42 and the valve body 41 are sequentially superimposed and pasted on the outer wall of the first film layer 11 from the outside to the inside. The valve body 41 and the prompt layer 42 are both in the shape of circular thin sheets. The valve body 41 is transparent, and the prompt layer 42 is a non-transparent color layer. The prompt layer 42 can be blue, which is convenient for users to quickly find the specific position of the air valve 4. The diameter of the prompt layer 42 is smaller than the diameter of the valve body 41 and the covering film 43. The membrane 43 is in the shape of a circular transparent film. The covering membrane 43 is pasted and covered on the surface of the prompt layer 42. The diameter of the covering membrane 43 is the same as the diameter of the valve body 41. The covering membrane 43, the prompt layer 42 and the valve body 41 are all coaxially arranged with the air hole 123. A plurality of valves 432 are arranged on the covering membrane 43. The plurality of valves 432 are arranged in a circle around the air hole 123 and correspond to the position of the prompt layer 42. The valves 432 are semicircular. The valves 432 are pasted and covered at the valve mouth of the covering membrane 43 to form a semicircular opening line 431.

[0033] Reference Figures 1 to 7 The method of using the vacuum sealing bag of the utility model is as follows:

[0034] The user puts food or other objects into the bag body 1 and presses the sealing clip 3 so that the sealing clip 3 seals the sealing portion of the bag body 1;

[0035] Place the bag 1 containing the object on the table;

[0036] Align the vacuum pump 5 with the air valve 4, so that the annular pressing portion 51 at the bottom of the vacuum pump 5 presses the entire annular edge of the air valve 4. At this time, the prompt layer 42 is located in the pressing portion 51;

[0037] The vacuum pump 5 is turned on to extract the gas above the gas valve 4. The middle part of the covering film 43 bulges outward in an arc shape under the suction of the vacuum pump 5 to form a transition space. At the same time, the multiple valves 432 rotate outward to open to form valve ports (such as Figure 7 As shown), at this time, the pores 123 of the first film layer 11 are fully opened, and the air in the bag body 1 enters the transition space of the covering film 43 through the pores 123 of the first film layer 11, the hole in the center of the valve body 41, and the hole in the center of the covering film 43 in sequence, and then the air in the transition space enters the vacuum pump 5 from multiple valve ports, and the air in the bag body 1 can be discharged smoothly;

[0038] Remove the vacuum pump 5 and manually press the top of the air valve 4 to make the covering film 43 and the valve 432 on the covering film 43 stick to the prompt layer 42 again, and the air holes 123 and multiple valves 432 are all closed, so that the external air can no longer enter the bag body 1.

[0039] The vacuum sealing bag of the utility model facilitates vacuuming by sticking an air valve 4 at the air hole 123 of the first film layer 11 of the bag body 1, thereby reducing the difficulty and cost of operation. At the same time, a plurality of protrusions 121 are arranged on the inner wall of the second film layer 12 of the bag body 1, which can not only assist in exhausting the residual air in the bag and improve the vacuum degree, but also increase the friction between the contents and the bag wall, improve the stability of the packaging, and thus achieve a more efficient and stable vacuum sealing packaging effect, thereby improving the packaging quality and user experience.

[0040] The above disclosure is only a preferred embodiment of the present invention, which cannot be used to limit the scope of protection of the present invention. Therefore, equivalent changes made within the scope of the patent application of the present invention are still within the scope covered by the present invention.
