又，除上述外，藉著於空氣通路21插入吸管等棒狀體， 將空氣通路21開放亦可。 11 587049 玖、發明說明（7 ) 於此開關閥2上，如圖2所+ + 所不，形成有^用密封部3。 此固定用密封部3 ,如圖2 邮- 9, y ^ 」所不’由用以將閥片材2a、 2b們密封之閥側固定用密封 y t a及用以將一側袋片材la與一 側閥片材2a之間密封之袋側固定 ^ 5 权·疋用密封部3b所構成。因此，

。此it迴冑32(32a)愈向後側寬度愈寬，藉著密封成略心形而 形成。藉著此迂迴部32(32a)將空氣通路21分成左右二邊。藉 此，由縮小部31(31a)離開的氣流將繞迂迴部32(32a)而流動 。於此迂迴部32(32a)中，朝膨脹部丨2流入方向的氣流，將順 著迂迴部32(32a)的形狀而自然地流動，相對於此，相反方向 的氣流，由於撞擊到迂迴部32(32a)(特別是其最寬的部份）， 而分成左右二股，故不會直接流入縮小部31(31a)。因此，由 12 20 587049 坎、發明說明（8 ) 於這樣的流動為不自然，故幾乎不會發生，藉此，迁迴部 32(32a)具有抑止空氣回流的功能。 、然後，迂迴部32(32a)的後側，形成有短線狀之密封體之 · $導出部33、34(33a、34a)。於本例中，於開關閥2之左右方向 L之中央部份，於前後方向w形成有一根較長之第一導出部

shown in Figure 2, and is formed with: $ 封 ° 卩 15 ° This reinforcement seal 15 is used to hold the air passage entrance i2a, and a sub-shape is formed on the expansion portion 12 side. Therefore, the air guide passage U 10 can be reinforced, and the description of the invention (6) The intersection of the swelling portion 12 and the H 1 'can prevent the swelling portion 12 from being damaged when it is filled with air. In addition, in the present invention, it is not necessary to form the reinforcing fee seal portion 15 and it may be omitted. ^ Later, in the lumbar expansion portion 12, near the air passage inlet 12a, in a state where the valve sheets 2a and 2b are trapped between the bag sheet and the bag, the four sheets are sealed by the left and right sides. 13 and the front and rear seals 14㈣, that is, the switch 2 is formed. That is, a switch room 2 is formed inside the expansion portion 12. As described later in detail, the on-off valve 2 is fixed to the bag sheet 1 a on one side by the bag-side fixing sealing portion 3 b of the fixing sealing portion 3. 10. The size of the valve sheets 2a, 2b in the front and rear directions W is smaller than that of the bag sheets 1a, 1b. This on-off valve 2 is formed by forming a flat cylindrical air passage 21 between the valve sheet 2a on one side and the valve sheet 2b on the other side as a flexible sheet. Air is conveyed from the air introduction path 丨 丨 toward the expansion section 12 15. Then, this air passage 21 is closed by the tightness of the valve sheet 2a on one side and the valve sheet 2b on the other side. Thereby, since the air passage 21 can be opened and closed, the on-off valve 2 has a valve function. Here, when the air passage 21 is opened, when the air is introduced from the air introduction passage π toward the expansion unit 20, the air flow between the valve sheet 2a on one side and the reading sheet 2b on the other side is opened. to make. In addition to the above, the air passage 21 may be opened by inserting a rod-shaped body such as a straw into the air passage 21. 11 587049 发明, description of the invention (7) On the on-off valve 2, as shown in Fig. 2 + +, a seal portion 3 is formed. This fixing sealing part 3 is shown in Fig. 2-9, y ^ `` where the valve side fixing seal yta is used to seal the valve sheets 2a, 2b, and is used to seal the side bag sheet la and The bag-side fixed seal between the one valve sheet 2a is formed by a sealing portion 3b. Therefore, the air passage 21 of the on-off valve 2 is referred to as a portion between the intermediate sheet 2a and the other side valve sheet 2b where the flap-side fixing seal portion is not formed. In this example, as shown in Figure 2U), the valve side 10 in the fixed position @ 定 职 封 部 3 is used to fix the sacral part 3a, from the air passage person σ 12a, in order, the reduction part 31 (3la), relocation The section 32 (32a), the lead-out sections 33, 34 (33a, ⑽. 15). The reduced section 31 (31a), in this example, is formed symmetrically with a linear sealing body inclined to the front-back direction ^, In this part, the width of the air passage 21 (the left and right squares L) gradually decreases toward the rear side. That is, the airflow in the direction of the reduction portion 31 (called inflow toward the expansion portion 12) is wider from the air passage 21 On the other hand, the narrower portion 31 (31a) enters, and the airflow in the opposite direction enters from the narrower side, so that the backflow of air can be suppressed. Then, on the rear side of the narrower portion 31 (31a), A detour portion 32 (32a) is formed. This iteration 32 (32a) becomes wider toward the rear side and is formed by being sealed into a slightly heart shape. The detour portion 32 (32a) divides the air passage 21 into left and right sides. By this, the air flow exiting from the reduction portion 31 (31a) will flow around the detour portion 32 (32a). In this detour portion 32 (32a), it flows into the expansion portion 2 The airflow flowing naturally follows the shape of the detour 32 (32a). In contrast, the airflow in the opposite direction is divided into the detour 32 (32a) (especially its widest part) and is divided into There are two left and right strands, so it will not directly flow into the reduction section 31 (31a). Therefore, from 12 20 587049 kan, invention description (8) such a flow is unnatural, so it hardly occurs, and the relocation section 32 ( 32a) has a function of suppressing the return of air. Then, a short linear seal is formed on the back side of the detour portion 32 (32a). $ Lead-out portions 33, 34 (33a, 34a). In this example, the switch In the central part of the left-right direction L of the valve 2, a longer first lead-out portion 33 (33a) is formed in the front-rear direction w on the left and right sides, and the shorter one is formed along the left-right direction. There are two lead-out sections 34, and the lead-out sections become air passages 2 and the air flows toward the expansion port IM2. The lead-out sections 33 and 34 are the rearmost side of the switch room 2, and divide the air spring · W ^ path 21 into a plurality of places. (* In this example) narrow passage. To this end, the air flow from the bulge 12 to the air passage 21 changes It is difficult to enter the air passage 21 'to reverse the flow to a certain extent. In this way, the valve-side fixing seal portion%' in the formed fixing seal portion 3 can pass air from the air introduction passage 11 toward the expansion portion 12 to the switch. The valve 2 is induced in the valve 2. This allows the airflow to smoothly flow into the swelling portion 12 through the air passage u, and in this example, because of the shape of the reduced portion 3 and the movement 32 as described above, The existence of the lead-out portions 33 and% makes it difficult for countercurrent to occur. _ Moreover, even if the air flows counter-current in the expansion portion 12, the portion corresponding to the person π of the air passage 21 is caused by the functions of the lead-out portions 33 and 34. Block, let ’s say that the machine enters the working gas passage 21, but as shown in FIG. 3 (C), it flows into the part between the expansion valve 2 and the valve 2 on the other side and the bag sheet 1b on the other side, so that this part expands. . Then, by this expansion, since the adhesion between the valve sheet 2a on one side and the valve sheet 2b on the other side is strengthened, a stronger backflow can be prevented. The sealing portion 3b for fixing the bag side of the sealing portion 3 is 13 587049 5 10 in plan view, and the description of the invention c 9) ', the sealing body 3a for the fixing is formed at the same position, and the bag side The fixing-side sealing portion 3b may attach the -side bag sheet la and the -side valve sheet 2a. Thereby, the 'on-off valve 2 is fixed with respect to the one side bag sheet ia. In this example, since the reduced portion 3l (3ia) of the bag-side fixing sealing portion 3b and the relocation small lead-out portion ⑽ ⑼ ⑼ are smaller than the front and rear ^ are arranged side by side at a small interval, even if the inflation portion 12 is filled with air to expand it As shown in FIG. 3⑻, the two-phase material—the side bag sheet ia is surely fixed. Also, the fixed switching valve 2 is in the expansion portion 12, and the expansion portion switching valve 2 is connected to the other side bag. As shown in Fig. 3 (c), the air pressure between the sheets lb is filled in the swelling part a, and it will be in close contact with the bag sheet H on one side and 'because the switching valve 2 is soft. Material, it will stick tightly along the side sheet & therefore, there is no conventional on-off valve 103 (shown in Figure? (E)), the on-off valve is divided by the sheet of the expansion portion 102 The curtain + bismuth 4 d ^ ~ the knife is separated, forming a wrinkle, so that the air leaks out, that is, 15 can effectively close the air passage 21. The following is implemented as one of the manufacturing devices of the sealing body with a switching valve of the present invention For example, the processing sequence will be described. In the manufacturing apparatus 5 set 51, the sheet conveying device 52, in this example, as shown in FIG. 4, The supply and fixing sealing part forming device 53 and the sheet supply amount adjusting device becoming device 56. 4 constituting devices 55 such as the rear fork sealing portion, and the left and right sealing portion forming devices 5 and ^ sheet 2a, 2b + In the part of the sheet feeding device J of the manufacturing apparatus 5 where no heat sealing is applied, specifically, left and right 14 20 587049 玖, invention description (10) The sealing part 13 is separated as one side of the air passage inlet 12a part The valve sheet 2a is coated with a coating material in advance. Then, the valve sheets 2a and 2b are stacked and rolled into a roll shape. The raw material is installed in a sheet supply device 51. The sheet supply device 51 rolls the raw material into a roll shape. The bag sheets 5a, 1b, and the valve sheets 2a, 2b are provided to each device supplier. This supply to each device is performed by a sheet conveying device 52 such as a rotary roller, etc. The sheet conveying device 52 simply moves each sheet in the long direction (left-right direction L), and for sealing processing, an error occurs in the long direction (left-right direction L 0). For this reason, a sheet supply is set in the middle Adjustment device 54. This sheet supply amount adjustment device 54 is composed of a sensor 54a and an adjustment roller 54b. In this example, the sensor 54a uses a photocell, and with this sensor 54a, it can measure the subsequent formation Fix the distance of the sealing portion 3. Then, based on the result of the measurement 15, 'the adjustment roller 54b is moved in the up-down direction to finely adjust the amount of movement of each sheet. In this example, the method of using the towel to male and seal each sheet is used. The lip is heat-sealed. Then, the seal is formed in three stages for men. First, the seal portion is formed by the shape, as shown in FIG. 5 (A), and the seal portion 3 is formed. Then, the seal portion 3 is formed. As shown in FIG. 5 (a), a constituent device 55, such as a front and rear seal portion, forms a front and rear seal portion 14 and a reinforcing seal portion 15. Then, the left and right sealing portions 13 are formed by the left and right sealing portion forming means 56 'as shown in FIG. 5 (C). Hereinafter, description will be made in accordance with the processing order. 15 587049 (1) Description of the invention (11) A raw material forming a roller shape is arranged in the sheet supply device 51. At this time, the clothing sheets 1a, 1b are arranged above and below, and the two sheets of valve sheets 2a, 2b which are stacked in a roll shape are disposed therebetween as described above. Then, the one-side bag sheet 1a and the valve sheets 2a and 2b are superposed, and the sealing part 3 for fixing part 5 is formed by the sealing part forming device 53 for fixing 5 as shown in FIG. Thereby, the one side bag sheet 1 a and the valve sheets 2 a and 2 b are integrated. In this way, by forming the fixing sealing portion 3 and inflating the expansion portion 12 with air, as shown in FIG. 3 (B), the on-off valve 2 can be reliably fixed to the side bag sheet la, which is effective.地 close the air passage 21. In addition, by the shape of the seal portion 3 for fixing 10, the air of the on-off valve 2 does not flow backward. After that, as described above, the fixing sealing portion 3 is integrated into one body. The one side bag sheet la and the valve sheet 2a, 讣 are inputted, and then each of these sheets la, 2a, 2b and the other side bag sheet = heavy ^, and the device 55 is formed by the front and rear seals, etc. As shown in FIG. 5 (B), 15 front and rear seal portions are formed. Next, the device 56 is formed with the left and right sealing portions, and the left and right sealing portions are formed as shown in FIG. 5 (0) to complete the sealing body. 20 The subsequent steps are not shown, but it is preferable to roll the sealing body roll formed into a long sheet shape. Cutting, folding, heat sealing, etc.-a series of steps to make an envelope: box-shaped cushioning body, etc. Of course, the step of adding air to the expanded portion of the assembled cushioning body or packing various goods is also used. It is better to protect the object, and it can be processed in various forms. The present invention is not limited to the above-described embodiment, and various changes can be made. 16 587049 发明, Description of the invention (12) For example, the switch in this example The structure of the room 2 is composed of two pieces: 5 is tightly closed, and the air passage 21 is closed. "7 pieces of cymbals are folded back to form the same structure. Conversely, it is also possible to combine-one piece of t material. Yes, various changes can be implemented. As shown in Figure 6 (A), _ Riding 2c, which is different from the opposite valve, is installed between ㈣% and 2b. One side of the valve sheet can be tight, You can also. About this valve body sheet: 10 closed by the inlet air passage 21, such as: by :: side_ 可, a shape 2c is juxtaposed, etc. will be ## valve body sheet invention The effect is dense = clear: the first, when the sealing body is filled with air, the on-off valve pair 15 20 is always tight. As a result, can the on-off valve be firmly fixed to the air? Two: This fixed on-off valve, by There will be no * air through riding / in the ± 34 sheets when filled into the sealed body, so there will be no sensitive folds in the on-off valve, there will be allergic folds and leakage, and it can be effectively used ~ again according to the first aspect of the present invention Second, in addition to the effect of the first-purpose effect: Bu °, fixed = is used to relocate the person who induces the air passing through the opening and closing valve to make the fixed sealing part relocatable to the milk. It ’s not easy, it ’s a κ shape, and the airflow capacity path does not cause air = allows the air to pass through the air smoothly. According to the third object of the present invention, in addition to the effects of the first or second object 17 587049 发明, invention Explanation (13) 'And there will be no wrinkles of air generated by the switching valve, and it can effectively block the air In addition, since the valve body sheet can effectively close the air passage, it can provide a mounting structure of an on-off valve that is less likely to cause air leakage. Also according to the "fourth object of the present invention", there can be provided a valve that does not have Device for manufacturing a sealing body with a switching valve whose air leaks from the air passage of the 5 switching valve [a simple illustration] FIG. 1 is a perspective view of a sealing body with a switching valve according to an embodiment of the present invention; FIG. 2 (A) is an enlarged explanatory diagram of an important part of the on-off valve in the sealed body having the on-off valve in this example, and FIG. 2 (B) is a sectional view taken along the line II-II of FIG. 2 (A); For example, a sectional view of a switching valve portion in a sealing body having a switching valve, FIG. 3 (A) shows a state where the expansion portion is not filled with air, and FIG. 3 (B) shows a state where the expansion portion is filled with air.
