[0001] The utility model relates to the technical field of packaging, in particular to a sealed packaging bag and a sealing clip thereof. Background Art
[0002] Sealed packaging bags can seal and protect the food and other contents contained inside to keep them fresh and store them. Sealed packaging bags are convenient for consumers to tear open the packaging bags directly and reach into the bag from the top opening to take out the contents, such as various food packaging bags. However, once consumers tear open the packaging bags, the contents of the packaging bags are exposed to the air. For some foods that are easily affected by moisture and spoilage, if consumers cannot consume them all at once, it is difficult to store them directly in the original packaging bags.
[0003] In the prior art, some packaging bags can use sealing clips to clamp the bag opening to prevent the contents in the packaging bag from being continuously exposed to the outside air. However, at this time, there is already a certain amount of air in the packaging bag. The air that has entered the packaging bag will also cause the food to become damp and deteriorate, which is enough to affect the taste of the food.
[0004] This type of sealed packaging bag and sealing clip still needs to be improved. Utility Model Content
[0005] In view of this, the purpose of the present invention is to provide a sealed packaging bag and a sealing clip thereof to solve the above problems.

DETAILED DESCRIPTION
[0026] In order to make the purpose, technical solution and advantages of the utility model clearer, the specific embodiments of the utility model are described in detail below in conjunction with the accompanying drawings. Examples of these preferred embodiments are illustrated in the accompanying drawings. The embodiments of the utility model shown in the accompanying drawings and described according to the accompanying drawings are merely exemplary, and the utility model is not limited to these embodiments.
[0027] It should also be noted that, in order to avoid obscuring the present invention due to unnecessary details, only structures and / or processing steps closely related to the solution according to the present invention are shown in the accompanying drawings, while other details that are not very relevant are omitted.
[0028] like Figure 1 and Figure 2 As shown, an embodiment of the utility model provides a sealing clamp for a sealed packaging bag, wherein the sealing clamp for the sealed packaging bag comprises an upper clamping strip 1 , a lower clamping strip 2 , a tube sleeve portion 3 and an air guide tube 4 .
[0029] One end of each of the upper clamping strip 1 and the lower clamping strip 2 is connected by a rotating shaft 5, so that the upper clamping strip 1 and the lower clamping strip 2 can be folded around the rotating shaft to fit together to clamp the sealed packaging bag placed therebetween. The other end of the upper clamping strip 1 is provided with a wedge block 11, and the other end of the lower clamping strip 2 is provided with a snap groove 21 matching the wedge block 11, so that the folded upper clamping strip 1 is snapped into the snap groove 21 through the wedge block 11 to fix the fitting state of the upper clamping strip 1 and the lower clamping strip 2. A pressing edge 211 is formed on the snap groove 21, and the pressing edge 211 drives the snap groove 21 to deform when being pressed, so that the wedge block 11 is removed from the snap groove 21.
[0030] The tube sleeve portion 3 includes an upper half ring 31 located in the middle of the upper clamping strip 1 and a lower half ring 32 located in the middle of the lower clamping strip 2. The upper half ring 31 and the lower half ring 32 are folded and assembled into an annular structure for fixing and clamping the air guide tube 4. The air guide tube 4 includes a tube body 41 and a tube cap 42. The tube body 41 is a hollow structure. The tube cap 42 is covered on the top of the tube body 41 to control the flow resistance of the tube body 41.
[0031] Combination Figure 3 As shown, the sealing clamp of the sealed packaging bag provided by the embodiment of the utility model is provided with a semi-ring structure on the upper clamping strip 1 and the lower clamping strip 2, so that the upper semi-ring 31 and the lower semi-ring 32 are folded and assembled into the tube sleeve part 3 of the fixed air guide tube 4. After the sealing clamp clamps the bag mouth of the sealed packaging bag, the air in the sealed packaging bag can be squeezed out of the sealed packaging bag from the tube body 41 of the air guide tube 4, and then the tube cap 42 is tightened to close the tube body 41 of the air guide tube 4, so that the contents in the packaging bag can be prevented from getting damp and deteriorating under the action of the air that has entered the bag. Even if the contents are not consumed in time after the sealed packaging bag is torn open, they can be stored for a long time to maintain the taste and flavor of food, etc., and ensure the user's experience. Moreover, the structural improvement of the sealing clamp is simple, easy to implement, low-cost, and can meet the needs of large-scale batch production.
[0032] The upper clamping strip 11 uses a wedge block 11 to fit into the buckle groove 21 of the lower clamping strip 2. The user only needs to press the pressing edge 211 to remove the wedge block 11 from the buckle groove 21, and quickly release the clamping state of the upper clamping strip 11 and the lower clamping strip 2. The method of use is convenient and easy to use.
[0033] On the basis of the clamping and fixing of the tube sleeve part 3, a fixing hole 320 is opened on the inner wall of the lower half ring 32, and a protrusion 43 cooperating with the fixing hole 320 is correspondingly arranged on the outer wall of the air guide tube 4, so that the protrusion 43 is clamped into the fixing hole 320 and fixed, so that the air guide tube 4 can be further fixed inside the tube sleeve part 3 more stably, and the setting of the protrusion 43 and the fixing hole 320 is convenient for the user to find the correct position to install the air guide tube 4.
[0034] The user needs to tighten the tube cap 42 to prevent outside air from entering the sealed packaging bag after the air inside the sealed packaging bag is discharged through the tube body 41. Therefore, the tube cap 42 needs to be easy to tighten, and the tube cap 42 is provided with anti-slip grooves.
[0035] In this embodiment, the upper clamping strip 1 and the lower clamping strip 2 are respectively provided with two elastic rubber strips 6, and the folded elastic rubber strips 6 of the upper clamping strip 1 and the elastic rubber strips 6 of the lower clamping strip 2 cooperate and abut against each other. After the upper clamping strip 11 and the lower clamping strip 2 clamp the bag opening of the sealed packaging bag, the relative elastic rubber strips 6 can be deformed and more closely cooperate and abut against each other, so that the sealed packaging bag part therebetween is clamped more tightly, and there are two pairs of elastic rubber strips 6, and the air needs to pass through two narrow areas, so the sealing degree is higher.
[0036] Furthermore, there is a hollow area between the two elastic strips 6 of the lower clamping strip 2. The bag surface of the partially sealed packaging bag can be clamped in the hollow area, so that the air flow channel between the clamped upper clamping strip 1 and the lower clamping strip 2 is more tortuous, and air is difficult to flow.
[0037] In this embodiment, the air guide tube 4 further includes a cross silicone valve 44 connected to the bottom end of the tube body 41 away from the tube cap 42. The function of the cross silicone valve 44 is that when the air inside the sealed packaging bag is squeezed out, the cross silicone valve 44 can be opened by the rapid airflow, and after the air inside is squeezed out, the outward airflow stops, and the cross silicone valve 44 is automatically closed, and the tube cap 42 is covered on the top end of the tube body 41, and the airflow is not enough to open the cross silicone valve 44 and enter the sealed packaging bag, thereby further improving the airtightness of the sealed packaging bag.
[0038] Exemplarily, the upper half ring 31 and the lower half ring 32 are silicone rings, and the cross silicone valve 44 is liquid silicone rubber.
[0039] The utility model also provides a sealed packaging bag, which includes a bag body 7 and the sealing clip as described above, wherein the bag body 7 is provided with a tearable bag opening, and the sealing clip is located beside the bag opening of the bag body and is clamped on two opposite sides of the bag body 7 to close the bag opening.
