Air valve for forming a bag into a vacuum sealed bag

This creation is a technical field of vacuum sealed bags, especially a gas valve that can form a bag into a vacuum sealed bag.

Usually, the food is usually stored in a refrigerated/frozen manner, and then sealed in a sealed box or a sealed bag. In order to keep it fresher, there is a way to vacuum it. If the space for refrigerating is considered, the vacuum is sealed in a sealed bag to save space. There is a patent system No. I360505 "vacuum one-way exhaust valve" and patent No. M422536 "vacuum exhaust valve of plastic packaging bag", which provides a valve on the bag body or the bag to make the inside of the bag or the bag. Vacuuming, if the bag or bag is damaged, the function of vacuum sealing will not be damaged, and there will be a patent number M415117 "sealed bag with removable valve" and patent number M480525 "removable" The vacuum bag one-way exhaust valve has the disadvantage of eliminating the waste of the bag or the bag, but the bag or the bag must first be provided with a hole for the valve installation, such a special bag or Packaging bags are not easy for people to choose, and there are still improvements.

In view of the foregoing problems, the present creator further studies and develops. Therefore, the main purpose of the present invention is to provide a gas valve for forming a bag into a vacuum sealed bag, which is mainly divided into an upper and a lower valve body, Lower valve The body is provided with a structure that can pierce the bag while being engaged with each other, the opening of the bag is sealed, and the air valve is evacuated to form a vacuum seal in the bag.

The present invention is a gas valve for forming a bag into a vacuum sealed bag. As shown in Figures 1 and 2, the gas valve 10 is divided into upper and lower valve bodies 20, 30, and the upper valve body 20 is provided with a soft upper film 21 The upper film 21 is covered with a hard upper tube body 22, and the upper film 21 is formed with an upper bottom surface 23 and an upper top surface 24. The upper tube body 22 is protruded with a through tube 221, and the through tube 221 is provided with a through tube. Top surface 24 The upper film 24 is provided with a valve 211 extending toward the channel 221 and trapped therein. The valve 211 is like a valve of the patent No. M415117 "sealed bag with a removable valve"; The body 30 is provided with a soft lower film 31, and the lower film 31 is covered with a rigid lower tube 32. The lower film 31 is formed with a lower top surface 33 and a lower bottom surface 34. The lower tube body 32 is convexly tapered. The cone tube 321 and the cone tube 321 are provided with an air passage 322 extending through the lower bottom surface 34. The cone tube 321 can be inserted into the passage 222 to penetrate therethrough, and the soft upper and lower films 21 and 31 are deformed and clamped to each other. The cone tube 321 and the through tube 221 form a piercing structure and a fastening structure.

In order to make the piercing structure easier to pierce the bag 40, the oblique opening 323 is sharpened at the end of the tapered tube 321, and the fastening structure is further stabilized. The end of the channel 222 is provided with a buckle 223. The rib 324 is disposed around the outer circumference of the cone tube 321 , and the buckle 223 and the rib 324 can be engaged and disengaged from each other; when the upper and lower valve bodies 20 and 30 are engaged with the upper and lower films 21 and 31 due to deformation When clamping each other, in order to prevent the vacuum pressure from being dissipated from the hole pierced by the bag 40, the airtight strip 231 is looped on the upper bottom surface 23 so that the air does not penetrate when the upper bottom surface 23 and the lower top surface 33 are closed.

Referring to FIG. 3 again, in order to allow air to be easily drawn out of the air passage 322 from the lower bottom surface 34, outer, middle and inner convex rings 341, 342, 343, outer, middle and inner convex rings 341, 342, 343 are disposed on the lower bottom surface 34. The air slots 3411, 3421, and 3431 are all provided. When the lower bottom surface 34 is in contact with the bag 40, the air can still flow out of the air bag 322 through the air grooves 3411, 3421, and 3431, and the outer ring 341 is further The inner and inner convex rings 342 and 343 are disposed in different planes. For example, the outer convex ring 341 is lower than the middle and inner convex rings 342 and 343, and the airflow blocking is further prevented. The concave ring 341 and the middle convex ring 342 are concave. Ring 344.

For the assembly situation, please refer to Figures 4 and 5, the lower valve body 30 is placed inside the bag 40 and the upper valve body 20 is engaged, and the cone 40 is pierced by the cone tube 321 to be caught in the passage 222 of the upper valve body 20 while being engaged. The upper and lower films 21, 31 clamp the bag 40 to each other due to deformation, so that the bag 40 is formed into a bag having a vacuum sealable as shown in Fig. 5. Therefore, the conventional bag 40 can be vacuumed by fitting the gas valve 10. Sealing, the object 60 is placed in the bag 40 provided with the air valve 10, and the opening of the bag 40 can be provided with a clamping member 50 for preventing air from entering. The clamping member 50 can be a common zipper or sealing clip, or even a hand held The bag 40 is clamped, and the valve body 20 is evacuated by a conventional vacuuming device, and vacuum-sealed as the air is drawn out of the bag 40.

The above embodiments are merely illustrative of the techniques of the present invention and their effects, and are not intended to limit the present invention. Anyone skilled in the art can modify and change the above embodiments without violating the technical principles and spirit of this creation. Therefore, the scope of protection of this creation should be as listed in the patent application scope mentioned later. .
