Description

Air buffer body with sealing body air-tight air-locking device and manufacturing method thereof

technical field

The present invention relates to an air cushioning device for inner packaging, in particular to an air cushioning body with a device for automatically closing and locking air in a sealing body and a manufacturing method thereof.

Background technique

It is a trend to heat-seal the resin film as the base material to form a sealed body, and use it as the cushioning material of the inner packaging after inflation. Generally, there are two types of air buffers. One is composed of independent air columns. Each air column has an independent air inlet. When inflating, each air inlet must be inflated, so it is time-consuming and uneconomical to inflate. In addition, the new type in Taiwan, China In the patent No. M255242, a plurality of heat-resistant prints are sandwiched between the upper and lower air valve membranes as the air nozzles for inflating air. Unfortunately, the inflating channels cannot automatically open the air inlets of each sealing body when inflated at one time. The other type consists of one or two inflation ports with non-independent air columns. The disadvantage is that if one is damaged, all the air columns will be degassed together, such as US Patent No. 5,427,830. In addition, these two types of air buffers only raise the inner membrane to increase the air pressure, but do not further study the method of locking the air. Therefore, the air in the air column after inflation cannot last for a long time without leaking. The above shortcomings make the practicability of the air buffers low.

China Taiwan Invention Patent No. 92113574 approved on May 20, 2003 discloses an installation structure for a switch valve of a sealed body, wherein the switch for air entering the sealed body uses two pieces of inner film and one side of the outer film to form a switch The passage of the valve, when inflated, the sealing body expands to block the passage. The patent only describes how to block the air in the sealing body from leaking out, but does not explain how to simplify the inflation. By design, air cannot automatically enter the seal.

Detailed ways

Please refer to FIG. 1A to FIG. 1C , which show the first embodiment of the air buffer body of the present invention, and the inner membrane adheres to the wall.

The air-filled buffer body includes: two inner membranes 1a and 1b interposed between two outer membranes 2a and 2b. The heat-resistant material 1c is formed between the two inner films 1a and 1b. The implementation is as follows:

First fold the inner membrane 1a, 1b and the outer membrane 2b, and apply heat seal 1d along the bottom of the heat-resistant joint 1c to form the air path 10, and set the bottleneck that is easy to plug, that is, the easy-to-plug section 11; and then combine with the outer membrane 2a Folding, applying heat-sealing lines 3, 4., 5, 6, 7, 8 to divide the sealing body into two areas, one is the inflatable channel area 3-4, and the other is the gas storage area 4-5, 6, 7 , 8 are heat-sealing edges, make these two districts be bounded by heat-sealing line 4, butt up and down. Due to the heat-resistant properties of the heat-resistant glue 1c in the air-filled channel area, the inner films 1a and 1b are not bonded after being heat-sealed at the heat-sealing point 2c, but the inner film and the outer film 2a, 2b will be bonded. After the processing of the heat-sealing line 4, the inner membranes 1a and 1b of this part will not be connected, and a gap is formed, which is called an air inlet 2d. When inflated, the inflatable channel 9a expands and pulls the outer membrane of this area, so that the air inlet 2d is indirectly opened. After inflation, the internal pressure of the air column increases and presses the inner membrane turning section k of the gas storage area, so that the inner membrane closes the air inlet 2d. Hold and seal so that air can only enter but not exit. The increase of the internal pressure in the gas storage area can tighten the bottleneck of the air passageway 10, so that the preset easy-to-plug subsection 11. is tightened to block the passageway, forming an air lock.

Please refer to FIG. 2 , which shows a second embodiment of the air buffer with the inner membrane placed in the middle.

The air-filled buffer body includes: two inner membranes 1a and 1b interposed between two outer membranes 2a and 2b. The heat-resistant material 1c is formed between the two inner films 1a and 1b. The implementation is as follows:

First stack 1a and 1b and apply heat seal 10 along the bottom of heat-resistant section 1c to form an air travel route and set an easy-to-stop bottleneck, that is, a small section 11 that is easy to plug, and then place 1a and 1b between the two outer membranes 2a and 2b , and apply heat-sealing lines 3, 4, 5, 6, 7, 8 on the outer film to divide the sealing body into two areas, one is the inflatable channel area 3-4, and the other is the gas storage area 4-5, 6, 7 , 8 are heat-sealing edges, make these two districts be bounded by heat-sealing line 4, butt up and down. Due to the heat-resistant properties of the heat-resistant glue 1c in the air-inflating area, the inner films 1a and 1b are still not bonded after being heat-sealed at the heat-sealing point 2c, but the inner film and the outer film 2a, 2b will be bonded. The gas storage area is processed by the heat-sealing line 4, and the inner membranes 1a and 1b of this part will not be heat-sealed due to the heat-resistant glue barrier, forming a gap called the gas inlet 2d. When inflated, the inflatable channel 9a expands and pulls the outer membrane in this area, so that the air inlet 2d is indirectly opened. After inflation, the internal pressure of the air column will cause the inner membranes 1a and 1b to press each other and close the air inlet, and the internal pressure will rise. It will tighten the preset bottleneck in the air passage, make the inner membrane close to block the air passage, and form an air lock.

Please refer to FIG. 3 , which shows a third embodiment of the air buffer, with a single piece of inner membrane attached to the wall.

The inflatable buffer body includes: two outer films 2a and 2b, one inner film 1a coated with heat-resistant glue 1c, and the inner film 1a is interposed between the two outer films 2a and 2b. The implementation is as follows:

First fold the inner film 1a and the outer film 2b and apply heat seal along the bottom of the heat-resistant joint 1c to form the air travel path 10 and set the bottleneck that is easy to plug, that is, the easy-to-plug segment 11; then fold it with 2a, and place it on the outer film Give the heat sealing line 3, 4, 5, 6, 7, 8 to divide the sealing body into two areas, one is the air channel area 3-4, the other is the gas storage area 4-5, 6, 7, 8 are heat sealing edges , so that the two areas are bounded by the heat-sealing line 4, butt up and down. Due to the heat-resistant properties of the heat-resistant glue 1c in the air-inflating channel area, the inner film 1a and the outer film 2b are still not connected after heat-sealing point 2c, but Intima 1a and adventitia 2a will be joined. After the processing of the heat-sealing line 4, the inner film 1a and the outer film 2b of this part will not be connected, and a gap is formed, which is called the air inlet 2d. When inflated, the inflatable channel 9a expands and pulls the outer membrane of this area, so that the air inlet 2d is indirectly opened. After inflation, the internal pressure of the air column increases and presses the inner membrane turning section k of the gas storage area, so that the inner membrane closes the air inlet 2d. Hold and seal so that air can only enter but not exit. And because the internal pressure of the gas storage area increases, the air will force the inner membrane to adhere to the outer membrane 2b, so that the bottleneck of the inner membrane air travel passage 10 will be blocked due to tightness, forming an air lock.

Please refer to FIG. 4 , which shows the fourth embodiment of the air buffer body, and the gas collection well is set.

The inflatable buffer body includes: two outer films 2a and 2b, one inner film 1a coated with heat-resistant glue 1c, and one inner film 1b.

The inner membranes 1a and 1b are interposed between the outer membranes 2a and 2b. The heat-resistant glue 1c is interposed between the inner membranes 1a and 1b, thus forming an arrangement of the outer membrane 2a, the inner membrane 1a, the heat-resistant glue 1c, the inner membrane 1b, and the outer membrane 2b. The implementation is as follows:

Due to the heat-resistant properties of the heat-resistant glue 1c, the inner film 1a and 1b are still not bonded after being heat-sealed at the heat-sealing point 2c, but 1b and 2b will be bonded, and 1a and 2a will also be bonded, so that the outer film will expand when inflated. pull away. First fold 1a and 1b with the outer film 2a, and apply heat seal 1d along the bottom of the heat-resistant joint 1c; because the heat seal of 1d makes this step set the bottleneck that is easy to plug, that is, the easy plug segment 11 and the air passageway 10; Fold with 2a again, apply heat sealing lines 3, 4, 5, 6, 7, 8 to divide the sealing body into two areas, one is the inflatable channel area 3-4, and the other is the gas storage area 4-5, 6 , 7, and 8 are heat-sealed edges, so that these two districts are bounded by the heat-sealed line 4, butt up and down. Because of the heat-resistant material 1c, the intima 1a, 1b at this part will not be connected, forming a gap. When the air-inflating channel fills a plurality of air cylinders at a time, it takes a long time to inflate, so the gas-collecting well and the extension road are set to still maintain an air-inflating port 9, and then the direct passage of each air column is made by hot pressing, that is, the extension channel 12. When inflating, the air Concentrate on the gas-gathering well 13 along the gas-filling port, and the air in the gas-gathering well 13 fills directly to the air inlet of each air column along the extension path, so that the inflation time of each air column can be shortened, and the inner membrane devices of the other air inlets are as shown in Fig. The examples shown in 1A to 1C, FIGS. 2A to 2B and FIGS. 3A to 3B are the same.
