Description

A mouth-blown air seal

technical field

The invention relates to an air sealing body, in particular to a mouth-blown air sealing body.

Background technique

The air-sealed body is made of resin film, which is heat-sealed to form an air column in a sealed state, and is equipped with an inflation port for inflation. When the gas is filled into the air column through the inflation port, the air-sealed body can be used for inner packaging as a buffer material.

The structure of the conventional air sealing body, such as the Japanese Utility Model Application No. 5-95851 "Fluid Sealing Bag" patent case, is to set independent check valves on each air column, and the inflow port at the top of each check valve Aligned with the heat-sealing line and connected together, when the gas is filled into the inflatable channel, the inflatable channel expands to open the check valve, so that the gas can be filled into the gas column. However, due to the fact that each check valve is independent of each other in this structure, each air column is inflated separately, and multiple air columns cannot be inflated at the same time. Moreover, it is quite cumbersome to manufacture, and each check valve must be placed one by one. Heat sealing is carried out at the predetermined position in the air column. Once the position of the check valve or the position of the heat sealing mold is shifted, it will not be possible to fix the check valve in the air column, or the inlet at the top will exceed the heat sealing mold. The subsequent heat sealing line will cause the gas to be filled into the inflatable channel. Although the inflatable channel expands, the check valve cannot be opened with the expansion of the inflatable channel, resulting in that the gas cannot be charged into the air column.

Another air seal structure such as Taiwan Invention Patent No. 00587049 "The installation structure of the switch valve of the seal and the manufacturing device of the seal with the switch valve", wherein the switch for air entering the seal adopts two inner membranes and one The side outer membranes are connected to each other to form the passage of the switch valve. When inflated, the sealing body expands to block the passage. This switch valve only describes how to block the air in the sealing body from leaking out, but when the air is introduced into the channel, it will expand when it is filled with gas. , even if the two outer membranes are pushed apart by the gas, the on-off valve will not be pulled apart with the action of the two outer membranes, so the two inner membranes of the on-off valve are still attached together and cannot Open the air passage inlet, if it is designed according to its design, the air cannot automatically enter the sealing body.

Therefore, how to design a sealing body that allows users to easily inflate by mouth blowing, and can automatically open the air inlet to continuously inflate to save inflation time, and can automatically close the air when inflating, and automatically lock after the air is closed. Air, to keep the long-term air not leaking, is the technical problem that the inventor of this case and the technical field person engaged in this related industry need to face.

Please refer to FIG. 1 , FIG. 2A , FIG. 2B , FIG. 3A , FIG. 3B , FIG. 4A and FIG. 4B , which are the first embodiment of the mouth-blown air sealing body of the present invention.

The mouth-blown air sealing body 1 of the present invention comprises: a first outer film 2a and a second outer film 2b, a first inner film 1a and a second inner film 1b, a heat-resistant material 1c, a first transverse heat-sealing line 3a and a second inner film Two transverse heat-sealing lines 3b, multiple vertical heat-sealing lines 3d, multiple neck heat-sealing lines 7, inflatable passages 9, multiple gas columns 6, and multiple heat-sealing blocks 5.

The first outer membrane 2a and the second outer membrane 2b overlap up and down.

The first inner membrane 1a and the second inner membrane 1b are interposed between the first outer membrane 2a and the second outer membrane 2b, and placed slightly lower on the top of the first outer membrane 2a and the second outer membrane 2b, the first inner membrane The width of the membrane 1a and the second inner membrane 1b is the same as that of the first outer membrane 2a and the second outer membrane 2b, and the length is shorter than that of the first outer membrane 2a and the second outer membrane 2b, the first inner membrane 1a and the second inner membrane 1 b each has a first side 11 and a second side 12 opposite to each other. In addition, a plurality of heat-resistant materials 1c (as shown in FIG. 2A ) are coated at intervals between the first side of the first inner film 1a and the first side 11 of the second inner film 1b, so that the heat-resistant materials 1c can be used as air circulation path.

Carry out heat-sealing by means of heat-sealing along the first transverse heat-sealing line 3a and the second transverse heat-sealing line 3b, so as to connect the two sides of the first outer film 2a and the second outer film 2b, and heat seal along the neck The line 7 is heat-sealed by heat-sealing means, so as to connect the first outer film 2a and the second outer film 2b and the first inner film 1a and the second inner film 1b. Therefore, heat sealing between the first transverse heat-sealing line 3a and the neck In the first outer membrane 2 a and the second outer membrane 2 b between the sealing lines 7 , an inflatable channel 9 through which gas can flow is formed, and an inflatable port 9 a is formed at one end of the inflatable channel 9 . Heat-sealing is carried out by means of heat-sealing along the plurality of vertical heat-sealing lines 3d, so as to connect the first outer film 2a and the second outer film 2b to form a plurality of air columns between the first outer film 2a and the second outer film 2b 6. After the heat-resistant material 1c is coated between the first inner film 1a and the second inner film 1b, a plurality of air inlets 2e are formed at the junction of the neck heat seal line 7 through heat sealing means, and each air inlet 2e corresponds to For each air column 6, the first inner membrane 1a and the second inner membrane 1b form a continuous air valve capable of inflating multiple air columns 6 at the same time.

Here, the neck heat-sealing line 7 is a roughly arc-shaped curve, protruding from the air column 6 toward the direction of the inflatable channel 9 (as shown in Figure 2A), and each neck heat-sealing line 7 corresponds to an air column 6, And it can be mainly composed of two first sections 71 , two second sections 72 and a third section 73 (as shown in FIG. 2B ). Wherein, the two first sections 71 are respectively connected to the two adjacent straight heat-sealing lines 3d; Part of the first inner film 1a and the second inner film 1b are coated with the heat-resistant material 1c, in other words, at least a part of the second section 72 is coated with the first inner film 1a and the second inner film 1b with the heat-resistant material 1c is superimposed; the third section 73 connects the two second sections 72, and is located at the place where the first inner film 1a and the second inner film 1b are coated with heat-resistant material 1c. On the whole, the third section 73 is located in an arc shape at the apex of the curve.

Special attention should be paid to: the neck heat seal line 7 at the place where the first inner film 1a and the second inner film 1b are coated with the heat-resistant material 1c will be adjacent to the first outer film 2a and the first inner film 1a, the second The two outer films 2b and the second inner film 1b, the first inner film 1a and the second inner film 1b are not bonded at the heat-resistant material 1c. The neck heat-sealing line 7 will be connected to the first outer film 2a and the second outer film 2b and the first inner film 1a and the second inner film 1b at the place where the heat-resistant material 1c is not coated, in other words, the neck heat-sealing line 7 Four pieces of film will be followed at the same time where the heat-resistant material 1c is not coated.

Continue to heat seal the first outer film 2a and the second outer film 2b and the first inner film 1a and the second inner film 1b to form a plurality of heat-sealed blocks 5 at predetermined positions on the sides of the plurality of air inlets 2e, Here, the heat-sealing block 5 is generally in the shape of a strip, a part of which is located in the inflatable passage 9, and a part is located in the air column 6 (as shown in Figure 2B). In addition, two adjacent heat-sealing blocks 5 are formed between There is an air-inducing channel 4, and the air-inducing channel 4 is located between the first intima 1a and the second intima 1b and is connected to the air inlet 2e (as shown in Figure 4A and Figure 4B). The heat-sealing block 5 is generally in the shape of a mountain, and the air-entraining channel 4 is generally in the shape of a valley.

When in use, the user only needs to blow air at the inflation port 9a. When the gas entering the inflation port 9a expands the inflation channel 9, the first outer membrane 2a and the second outer membrane 2b are pulled apart in the longitudinal direction. The first outer membrane 2a and the second outer membrane 2b expand from a flat state to a three-dimensional shape with a radian (as shown in Figure 3A), because the place where the heat-sealing block 5 is not set will expand due to inflation, and the heat-sealing block 5 is set It will not be inflated and expanded, so the inflatable channel 9 is compressed in the lateral direction due to the natural drop when inflated (as shown in Figure 3B), so that the first outer membrane 2a and the second outer membrane 2b forming the inflatable channel 9 are tightened. Displacement is generated in the lateral direction to use the heat-sealing block 5 to squeeze the first inner film 1a and the second inner film 1b, and drive the first inner film 1a and the second inner film 1b along with the first inner film 1b through the third section 73 The outer membrane 2a and the second outer membrane 2b are pulled apart in the longitudinal direction, so as to automatically open the air inlet 2e (as shown in Figure 4A and Figure 4B), that is, the heat-sealing block 5, which is roughly in the shape of a mountain peak, is in the shape of a valley. The air-inducing duct 4 is squeezed, and the first inner membrane 1a and the second inner membrane 1b are pulled apart in the longitudinal direction along with the first outer membrane 2a and the second outer membrane 2b through the third section 73, so that The first inner film 1a and the second inner film 1b of the air-introduction channel 4 are pulled apart, so that the first inner film 1a and the second inner film 1b are pre-coated with a heat-resistant material 1c and then heat-sealed to form a gap that is naturally squeezed open.

Since the air inlet 2e is automatically opened, one inflation channel 9 can inflate a plurality of air columns 6 at the same time, and there is no need to inflate each air inlet 2e after positioning, which can save inflation time, and because each air column 6 is independent of each other, some air columns 6 Damage will not affect the overall cushioning effect of the air-tight body 1 . In addition, the user only needs to blow air at the inflation port 9a to inflate each air column 6 without using a high-pressure inflator, which makes the inflation operation simpler and more convenient.

After the filling gas enters the gas column 6 through the air-inducing channel 4 and the gas inlet 2e, the internal pressure of the gas in the gas column 6 presses the second side 12 of the first inner membrane 1a and the second inner membrane 1b, making the first inner membrane 1a and the second inner membrane 1b are attached together to seal the gas column 6 so that the gas does not leak out and achieves the effect of holding breath. Here, the first inner membrane 1a and the second inner membrane 1b are suspended in the air column 6 by the pressure of the gas, or the first inner membrane 1a and the second inner membrane 1b can be connected with the first outer membrane 2a or the second outer membrane. The membrane 2b is next to each other. After the gas enters the air column 6, the first inner membrane 1a and the second inner membrane 1b are attached to the first outer membrane 2a or the second outer membrane 2b to close the air column 6 .

Please refer to FIG. 2B , in some embodiments, the gas channel 14 can be formed on the first inner film 1 a and the second inner film 1 b by means of heat sealing. Here, the first inner film 1a and the second inner film 1b are heat-sealed between the neck heat-sealing line 7 and the second side 12 to form a gas channel 14, and the gas channel 14 can be mainly composed of the converging area 141, The guide area 142 and the diversion area 143 are formed. Wherein, the converging area 141 is adjacent to the neck heat sealing line 7, and is formed between two straight heat sealing lines 3d, and one end of the converging area 141 protrudes to the inflatable channel 9; the guiding area 142 is connected to the converging area 141, and More than one path can be provided for gas flow; the diversion area 143 connects the guide area 142 and the second side 12, and the diversion area 143 has a plurality of paths, the number of which is greater than the number of paths provided by the guide area 142, and , each path of the diversion area 143 has an outlet 143a, and the outlet 143a is smaller than the junction of the diversion area 143 and the guide area 142 . Therefore, when the gas enters the gas channel 14 from the gas inlet 2e, it first gathers in the converging area 141 , then flows to the diverging area 143 through the path provided by the guiding area 142 , and then enters the gas column 6 along the diverging area 143 . Since the outlet 143a is smaller than the junction of the diverting area 143 and the guiding area 142, the gas in the gas column 6 will not flow back through the outlet 143a to cause gas leakage.

Please refer to FIG. 5A and FIG. 5B , which are the second embodiment of the mouth-blown air sealing body of the present invention.

In this embodiment, the heat-sealing block 5 can be provided with an air guiding part 51, wherein the air guiding part 51 has 3b) is a gradually expanding plane or arc, and it is arranged in the inflatable channel 9. When the gas entering the inflatable port 9a expands the inflatable channel 9, the gas in the inflatable channel 9 can be guided by the gas guide part 51 Enter the bleed air channel 4 and the air inlet 2e to effectively increase the inflation rate.

Please refer to FIG. 6 , which is a third embodiment of the mouth-blown air sealing body of the present invention.

In this embodiment, the heat-sealing block 5 can be connected to the elongated positioning portion 52 at the bottom of the air guiding portion 51 . Here, the positioning portion 52 is connected to the first side 11 of the first inner film 1a and the second inner film 1b and the first outer film 2a and the second outer film 2b, and the second transverse heat-sealing line 3b is located in the positioning portion 52 And the air inlet 2e is located at the side of the positioning portion 52 . Therefore, even if the position of the first inner film 1a and the second inner film 1b or the heat-sealing mold deviates and does not fall out of the positioning portion 52 during the manufacturing process, the first inner film 1a can still be heat-sealed along the second transverse heat-sealing line 3b. The inner membrane 1a, the second inner membrane 1b, the first outer membrane 2a, and the second outer membrane 2b do not affect the structure of the air inlet 2e and its inflation function, and solve the problem that the conventional sealing body cannot be inflated after heat sealing due to the position deviation of the air valve. And other issues.

In addition, in the present invention, the air guide part 51 can be connected to the first side 11 of the first inner film 1a and the second inner film 1b and the first outer film 2a and the second outer film 2b, and the heat sealing line 3b is located at the air guide part 51 and at the top end of the non-air guide part 51, the air inlet 2e is located on the side of the air guide part 51.
