Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments.
As shown in fig. 1 and 2, the rapid deflation gas column bag comprises an upper film 1, a lower film 2 and a gas valve film 3, wherein the peripheries of the upper film 1 and the lower film 2 are sealed and only an inflation inlet is reserved to form a bag body 4, the bag body 4 is provided with a vertical sealing and cutting line 5 which does not penetrate through the whole bag body 4 to form a gas column cavity 6 and an air inlet channel 7, the gas valve film 3 is arranged between the gas column cavity 6 and the air inlet channel 7, the inflation inlet 8 is over against the air inlet channel 7, the outer side of the bag body 4 is provided with a tearable strip 9, the tearable strip 9 is transversely connected to the outer side of the gas column cavity 6, the tearable strip 9 is in thermal bonding connection with the bag body 4, and the tearable strip 9 and each gas column cavity 6 are provided with bonding points 91.
Because the tearable strip 9 is thermally adhered to the bag body 4, when the user pulls the tearable strip 9, the tearable strip 9 will bring up the material at the bonding point 91 on the bag body 4 together, so that the bag body 4 is damaged, the gas can be discharged, and the exhaust is realized. Meanwhile, in the production of the common gas column bag, because a large number of heat sealing processes are adopted, heat sealing equipment is greatly arranged in a gas column bag production workshop, the tearable strip 9 and the bag body 4 are designed to be thermally adhered, the existing heat sealing equipment can be utilized without adding other processing equipment, the processing of the rapid gas release gas column bag can be realized, the production process is convenient and efficient, and the cost is low.
There are three examples of how the tear tape 9 is thermally bonded:
in a first embodiment, the tearable strip 9 is directly heat bonded to the pouch body 4 after the air column pouch is produced as in conventional production. Such a production mode is undoubtedly the simplest, but at this time, the tearable strip 9 is stuck with the upper film 1 and the lower film 2, and after inflation, the air column can generate a pit, so that the appearance and the use are affected, and when the tearable strip 9 is pulled, all the air columns are difficult to be smoothly damaged, and the effect is not good.
The following two examples do not have the above problems:
in the second embodiment, a high temperature ink layer 10 is coated on the side of the upper film 1 facing the lower film 2 and corresponding to the bonding point, and the tear tape 9 is bonded to the outer side of the lower film 2. The scheme skillfully uses the principle that the air valve membrane 3 forms the air inlet. In a general gas column bag manufacturing process, the gas valve film 3 needs to be heat-sealed between the upper film 1 and the lower film 2 while leaving the gas inlet, and thus a pattern of the gas inlet is generally applied to the gas valve film 3 using a high-temperature ink. At the time of heat sealing, the film coated with the high-temperature ink cannot be melted by high temperature, and therefore cannot be bonded to form the air inlet, and the other positions are heat sealed.
By using the principle, as shown in fig. 3, a high temperature ink layer 10 is coated on the position of the upper film 1 corresponding to the bonding point 91, then the air column bag is manufactured according to the general production process, and finally the removable strip 9 and the lower film 2 are hot pressed by using the point sealing mold 11, and due to the effect of the high temperature ink layer 10, the upper film 1 and the lower film 2 cannot be hot-bonded, so that the complete air column can be formed after inflation.
As a third example, as shown in fig. 4 and 5, a high temperature ink layer 10 may be applied to the tearable strip 9 corresponding to the vertical dividing line 5. This example also utilizes the high temperature ink principle, but the manufacturing process is completely different. In this embodiment, the tear strip 9 is initially heat bonded to the top film 1 or the bottom film 2 and then processed in accordance with conventional air column bag production modes. Under the process, in order to prevent the tearable strip 9 and the bag body 4 from being thermally bonded together by the column sealing mold 12 in the column sealing process, the high-temperature ink layer 10 is coated on the tearable strip 9 corresponding to the vertical dividing line 5. Thus, the complete air column can be formed after the air is inflated.
Further, as shown in fig. 2, both ends of the tearable strip 9 are extended out of the bag body 4 to form free pulling portions 92. Both ends of the tearable strip 9 are formed with a pulling part 92, so that a user can conveniently pull the tearable strip 9 at any side, and meanwhile, the tearable strip 9 is prevented from continuing to perform deflation operation after being broken in the middle of pulling once.
Preferably, as shown in fig. 6, the bonding point 91 is provided at an intermediate position in the width direction of the air column chamber 6. Aerify the back, the gas column is comparatively concentrated at the summit position atress, will bond 91 point settings on the summit, can improve the destruction success rate that can tear strip 9.
Meanwhile, the adhesive point 91 is annular. Design into the annularity with bond point 91, guaranteed the bonding area on the one hand, on the other hand makes the power of tearing the in-process take place certain change, improves and tears the success rate, also can effectively increase simultaneously and tear the hole for exhaust.
In this embodiment, the tearable strip 9 is thicker than the pouch 4. The thicker tab thickness ensures that the tearable tab 6 can pull all the adhesive points 91 apart.
In addition, the length of the tearable strip 9 between the two adhesive points 91 is longer than the distance between the two adhesive points 91 on the pouch 4. Since the air column bag is often used for winding the article, if the tear-off strip 9 has no margin between the two adhesive points 91, the tear-off strip may form a resistance during winding, which may make it inconvenient to use and bundle.
The invention also provides a production process of the air column bag, which is used for producing the quick-release air column bag adopting the second embodiment of the hot-sticking tear-off strip 9 and sequentially comprises the following steps:
s1, point-coating high-temperature ink on one side of an upper film 1, and drying;
s2, heat-sealing the air valve film 3 on the surface of the upper film 1 coated with the high-temperature ink;
s3, coating high-temperature ink on the upper film 1, and facing the surface of the upper film 1, which is heat-sealed with the air valve film 3, to the lower film 2, and heat-sealing the upper film 1 and the lower film 2 together through a heat-sealing die to form a bag body 4;
s4, completing a vertical sealing and cutting line 5 through a column sealing mold 12 to form a gas column cavity 6;
s5, performing transverse sealing, wherein the transverse sealing comprises an upper heat sealing strip, an air inlet channel heat sealing strip and a lower heat sealing strip;
and S6, thermally sticking the tearable strip 9 on the lower film 2 through the point-sealing mold 11, wherein the hot head of the point-sealing mold 11 is opposite to the high-temperature ink points on the upper film 1.
By adopting the production process, S2-S5 are the production process flow of the common air column bag, two processes are added at the head and the tail of the whole process, and the equipment and the process of the middle process do not need to be changed, so that the production line can be switched randomly in the production of two products, and the manufacturability is good.
In summary, the above description is only a preferred embodiment of the present invention and should not be taken as limiting the invention, and any modifications, equivalents, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
