Description

  The present invention relates to an exhaust valve for a compression bag provided in a bag body that stores an item stored in a compressed state by degassing the inside, and a compression bag including the same.

  As an exhaust valve for a compression bag provided in a bag body that stores an item stored in a compressed state by degassing the interior, for example, an exhaust valve for a compression bag described in Patent Document 1 is known.

  The exhaust valve described in Patent Document 1 has a cylindrical coupling portion protruding upward at the center, and an upper base in which the inside of the cylinder is formed as an exhaust passage, and a central portion facing the exhaust passage. And a base formed by integrally connecting the upper base and the lower base with a part of the bag sandwiched from inside and outside, and an exhaust of the base. A valve body that is disposed in the road and opens and closes the exhaust hole by its vertical movement, and an exhaust gas provided at the center portion that is detachably attached to the base while the center portion of the valve body is pressed against the base. It is comprised from the inlet which connects with a path | route, and the cover body which has an external air intake port provided in the edge and connected with an exhaust path.

  To use a compression bag equipped with the exhaust valve for the compression bag, connect a suction pipe such as a vacuum cleaner to the suction port in the center of the lid, and operate the vacuum cleaner etc. in this state to perform suction To start. By this suction operation, the peripheral portion of the valve body is sucked and floats, and the exhaust hole of the base is opened by the lift of the valve body. As a result, the air inside the bag body is sucked from the exhaust hole through the exhaust path to the intake port of the lid body that communicates therewith.

  When most of the air inside the bag body is deaerated, the outside air is sucked from the outside air intake port provided exclusively in the lid body. Thereby, the load of a vacuum cleaner etc. is reduced.

  When the suction operation of the vacuum cleaner or the like is stopped in this state, the valve body drops due to its own weight and the negative pressure inside the bag body, closes the exhaust hole, and the stored item inside the bag body is in a compressed state. Retained.

JP 2007-161337 A

  Here, generally, like the exhaust valve for a compression bag of Patent Document 1, most of the air inside the bag body is degassed, and the stored items inside the bag body are compressed and used at a high compression rate. . However, depending on the stored item, the stored item and the bag may be damaged when compressed at a high compression rate. Specifically, for example, when storing a feather futon as storage, the shaft of the feather inside breaks, the tip of the shaft of the feather pierces the bag body, opens a hole in the bag body, or after the bag body is released The recovery rate of feather futon was getting worse. In order to eliminate such inconvenience, it may be possible to stop the suction operation of a vacuum cleaner etc. at an early stage and compress the stored item at a low compression rate, but it is difficult to understand the timing of the end of compression, and the stored item It was difficult to compress properly.

  An object of the present invention is to provide an exhaust valve for a compression bag capable of appropriately compressing a stored item by making the compression rate changeable according to the stored item.

  The exhaust valve for a compression bag according to the present invention is provided in a bag body that stores a stored item in a compressed state by degassing the inside. The compression bag exhaust valve is attached to the bag body, and has a base formed with a communication path that connects the inside and the outside of the bag body, a lid attached to the base, and opens and closes the communication path A check valve that is provided in the communication path so as to allow the outflow of air from the inside of the bag body to the outside. The lid body communicates with the communication path, is connected to an intake nozzle that sucks out the air inside the bag body, and discharges the air inside the bag body, and the inside air discharge port A first outside air inlet communicating with the first outside air inlet. The first outside air inlet is configured such that its opening area can be changed.

  According to this configuration, the lid body communicates with the communication path, and is connected to an intake nozzle that sucks out the air inside the bag body, and discharges the air inside the bag body. Have Therefore, when the air inside the bag body is sucked from the inside air discharge port by a vacuum cleaner or the like provided with the intake nozzle, the air inside the bag body passes through the communication passage. Then, the air is sucked into the intake nozzle from the inside air discharge port. Further, according to the above configuration, the lid body has the first outside air intake port communicating with the inside air discharge port, so that the air inside the bag body can be obtained by a vacuum cleaner or the like provided with the intake nozzle. When the air is sucked in, outside air is taken in from the first outside air inlet by the suction force. Further, according to the above configuration, since the opening area of the first outside air inlet is configured to be changeable, the user adjusts the suction force for sucking the air inside the bag body. be able to. For example, when the user reduces the opening area of the first outside air intake, the outside air taken in from the first outside air intake decreases, so that the suction force for sucking the air inside the bag body is increased. Become stronger. Therefore, the compression rate of the stored item after suction increases. On the contrary, if the user increases the opening area of the outside air intake, the outside air taken in from the first outside air intake increases, so that the suction force for sucking the air inside the bag body is weak. Become. Therefore, the compression rate of the stored item after suction is reduced. Thus, since the user can change the compression rate according to the stored items, the stored items can be appropriately compressed.

  The said structure WHEREIN: The said base | substrate may have a cylindrical communicating path formation wall which forms the said communicating path in the center part. The communication path forming wall may have a communication path opening that opens into the communication path. The lid body may be attached to the base body so as to be rotatable about the communication path forming wall, and may have an opposing wall facing the communication path forming wall. The first outside air intake may be provided in the opposing wall and configured to be able to change an opening area thereof by overlapping with the communication path opening.

  According to this configuration, since the lid body is attached to the base body so as to be rotatable about the communication path forming wall, the user rotates the lid body relative to the base body. Thus, the opening area of the outside air inlet can be adjusted by adjusting the overlap amount of the outside air inlet with respect to the communication passage opening.

  In the above configuration, the lid body may include a ceiling wall portion where the inside air discharge port is opened and the intake nozzle contacts, and a hanging wall portion depending downward from a peripheral edge portion of the ceiling wall portion. Good. A second outside air intake port communicating with the first outside air intake port may be opened in the hanging wall portion.

  According to this configuration, since the second outside air intake opening communicating with the first outside air intake opening is opened in the hanging wall portion, the second outside air intake opening is in a direction different from the inside air discharge opening. Open toward. Therefore, even if the intake nozzle is brought into contact with the top wall, the second outside air intake is not blocked by the intake nozzle. Accordingly, when the air inside the bag body is sucked from the inside air discharge port by a vacuum cleaner or the like provided with the intake nozzle, the outside air is surely taken in from the outside air inlet. The suction force can be adjusted reliably.

  The said structure WHEREIN: The said top wall part may be formed shorter than the internal diameter of the said intake nozzle, and may have a protruding part which protrudes in the direction opposite to the said communicating path.

  According to this configuration, even if the intake nozzle is displaced from the top wall portion, the raised portion is in contact with the inner surface of the tip of the intake nozzle, so that the intake nozzle may be greatly displaced from the top wall portion. It is suppressed.

  The compression bag which concerns on this invention is provided with the bag body provided with the valve attachment port which connects inside and outside, and the said exhaust valve for compression bags attached to the said valve attachment port.

  According to this configuration, the compression bag includes the compression bag exhaust valve. For this reason, the user can change the compression rate in accordance with the stored item, so that the stored item can be appropriately compressed.

  According to the exhaust valve for a compression bag according to the present invention, the user can change the compression rate in accordance with the stored items, so that the stored items can be compressed appropriately.

The ring-shaped protrusion 37 is formed in an arc shape in cross section, and is fitted in the fitting groove 27 of the lid attachment portion 50 of the base body 9. Thereby, the lid body 10 is prevented from being detached from the base body 9 and can be rotated in the circumferential direction with respect to the base body 9.

  The partition wall 44 is formed in a substantially rectangular flat plate shape, and is connected to the base body mounting wall 31 and the opposing wall 42. The partition wall 44 is formed with a cutout portion 44a cut out in a V shape from the outside in the radial direction of the lower end edge thereof. Two partition walls 44 are arranged at positions 180 degrees apart from each other with respect to the central axis of the opposing wall 42. Each partition wall 44 is arranged at a position 90 ° away from each first outside air inlet 43. Thereby, when the user fits the lid body 10 into the base body 9, the partition wall 44 comes into contact with the lid body regulation wall 23 of the base body 9, so that the lid body 10 is displaced from the base body 9. Is prevented from being fitted. Further, when the user rotates the lid body 10 with respect to the base body 9 in a state where the lid body 10 is fitted in the base body 9, the partition wall 44 comes into contact with the lid body regulation wall 23, thereby Rotation is regulated.

  The inclined wall part 40 is demonstrated with reference to FIG. Four inclined wall portions 40 are arranged at positions adjacent to the second outside air intake 36. Specifically, the inclined wall portion 40 is disposed at a position adjacent to the second outside air intake 36 when viewed from the radial direction of the outer peripheral edge portion of the nozzle contact surface 30a of the top wall portion 30, and is downwardly directed downward. A substantially rectangular inclined wall surface 40a that is long in the circumferential direction, and a right triangular triangular inclined side wall surface 40b that extends downward from both side edges in the longitudinal direction of the inclined wall surface 40a.

  The cover portion 32 protrudes radially outward from the base body mounting wall 31, and is opposed to the bag body fixing flange portion 26 of the base body 9 in the vertical direction, and the second outside air inlet 36 on the upper surface of the base body facing portion 32a. An arrow c indicating the rotation direction of the lid body 10, and a notch 38 cut out in a substantially U shape from a position facing the arrow c on the outer peripheral edge of the base body facing portion 32a, And a triangular convex portion 39 formed in the cutout portion 38.

  The base facing portion 32 a is between the second outside air inlet 36 of the base mounting wall 31 and the ring-shaped protrusion 37 and between the inclined wall portions 40, 40 adjacent in the circumferential direction of the base mounting wall 31 in the radial direction. It protrudes outward (see FIG. 2). Both ends of the substrate facing portion 32a in the direction along the substrate mounting wall 31 are connected to the lower edge of the inclined side wall surface 40b of the inclined wall portion 40 (see FIG. 7).

  The convex portion 39 is disposed at the center of the notch 38. The user can identify the direction in which the lid 10 can rotate by the convex portion 39 and the through hole 28 of the base body 9. For example, when the convex portion 39 is positioned at the end of the through hole 28, the user can rotate the lid 10 in the direction in which the through hole 28 is formed.

  FIG. 8 is an exploded perspective view of the compression bag exhaust valve 3. The compression bag exhaust valve 3 is assembled as follows. A method for assembling the compression bag exhaust valve 3 will be described with reference to FIGS. First, the user installs the check valve 11 on the valve seat 48 of the base body 9. Specifically, the user inserts the stem portion 11 b of the check valve 11 into the valve mounting hole 14 of the base 9, and causes the bulging portion 11 c to contact the fixed wall portion 16. In this state, the valve surface portion 11 a of the check valve 11 is in close contact with the entire circumference of the protrusion 19 of the valve seat portion 48. Next, the user inserts the base mounting wall 31 of the lid 10 into the lid mounting portion 50 of the base 9 and fits the ring-shaped protrusion 37 of the lid 10 into the fitting groove 27 of the base 9. The lid 10 is attached to the base 9. Accordingly, the lid body 10 is prevented from being detached from the base body 9 and the user can rotate the lid body 10 with respect to the base body 9.

  Next, the usage state of the compression bag exhaust valve 3 will be described. The compression bag 1 configured as described above is used as follows. FIG. 9 is a view showing a state in which the first notch 20 and the first outside air inlet 43 of the compression bag exhaust valve 3 are overlapped in the radial direction. FIG. 10 is a view showing a state where the opening area of the first outside air inlet 43 of the compression bag exhaust valve 3 is small. FIG. 11 is a view showing a state in which the second notch 21 and the first outside air inlet 43 of the compression bag exhaust valve 3 are overlapped in the radial direction. FIG. 12 is a view showing a state where the opening area of the first outside air inlet 43 of the compression bag exhaust valve 3 is large. FIG. 13 is a view showing a state in which the intake nozzle 45 is connected to the inside air discharge port 33 of the compression bag exhaust valve 3.

  First, a case where the user wants to greatly compress the items stored in the bag body 2 (for example, when the compression ratio of the futon is about 70%) will be described. First, the user grasps the base body mounting wall 31 of the lid 10, and as shown in FIGS. 9 and 10, the position where the first outside air intake port 43 of the base body 9 overlaps the first notch 20 of the base body 9 in the radial direction. Rotate lid 10 until Thereby, the 1st external air inlet 43 is set to a small opening area, as shown in FIG. Next, as shown in FIG. 13, the user inserts a protrusion 46 protruding from the tip of the intake nozzle 45 of a vacuum cleaner or the like into the recess 35 of the top wall portion 30 and places the tip of the intake nozzle 45 on the ceiling The intake nozzle 45 and the inside air discharge port 33 are connected to contact with the nozzle contact surface 30 a of the wall portion 30. At this time, since the protrusion 46 contacts the recess 35 and the raised portion 34 contacts the inner surface 45a of the tip of the intake nozzle 45, the intake nozzle 45 remains in the nozzle even if a force acts on the intake nozzle 45. There is no deviation from the contact surface 30a. Therefore, the user can stably suck the air in the inside “a” of the bag body 2 through the intake nozzle 45.

  When the suction of the intake nozzle 45 is started, the valve surface portion 11a of the check valve 11 is pulled by the suction force of the intake nozzle 45, and the communication path 12 is opened. And the air inside the bag body 2 flows out from the inside air discharge port 33 to the outside b through the communication path 12. On the other hand, the outside air that has flowed into the communication passage 12 through the second outside air inlet 36 and the first outside air inlet 43 by the suction force of the intake nozzle 45 flows out from the inside air outlet 33 to the outside b. At this time, since the opening area of the first outside air inlet 43 is small, the outside air taken into the communication path 12 from the first outside air inlet 43 by the suction force of the intake nozzle 45 is small. Therefore, the suction force for sucking air inside the bag body 2 of the intake nozzle 45 is large, and the stored items are greatly compressed. Thereafter, when the user stops the suction operation by the intake nozzle 45, the check valve 11 returns to its original shape and comes into close contact with the protrusion 19 of the valve seat portion 48 to close the communication path 12. Thereby, the stored item in the inside a of the bag body 2 is held in a compressed state.

  Next, a case where the user wants to compress the items stored in the bag 2 softly (for example, when the compression ratio of the futon is about 50%) will be described. The description of the same parts as those in the case of greatly compressing the stored items will be omitted. First, the user grasps the base body mounting wall 31 of the lid 10, and the first outside air inlet 43 of the lid 10 overlaps the second notch 21 of the base 9 in the radial direction as shown in FIGS. The lid 10 is rotated to the position. At this time, as shown in FIG. 12, since the opening area of the first outside air inlet 43 is large, a large amount of outside air is taken into the communication path 12 from the first outside air inlet 43 by the suction force of the intake nozzle 45. Therefore, the suction force for sucking the air inside the bag body 2 is small, and the stored items are softly compressed.

  The compression bag exhaust valve 3 and the compression bag 1 described above are one embodiment of the present invention, and the specific configuration thereof can be appropriately changed. Hereinafter, the second to eleventh embodiments will be described.

(2) Second Embodiment FIG. 14 is a perspective view of the base 9 of the compression bag exhaust valve 3 according to a second embodiment. FIG. 15 is a perspective view of the compression bag exhaust valve 3 according to the second embodiment. FIG. 16 is a perspective view of the lid 10 of the compression bag exhaust valve 3 according to the second embodiment. About the structure which has the function similar to 1st Embodiment, the code | symbol similar to 1st Embodiment is attached | subjected and the description is abbreviate | omitted. That is, the compression bag exhaust valve 3 according to the second embodiment is different from the first embodiment in the specific configuration of the bag body fixing flange portion 26 and the lid body 10.

  In the first embodiment, the bag body fixing flange portion 26 of the base body 9 has the through hole 28 as shown in FIG. 3, but may not have the through hole 28 as shown in FIG. 14. In other words, the through hole 28 is provided so that the user can identify the direction in which the lid 10 can rotate. Instead, the user can set an appropriate position of the lid 10 with respect to the base body 9. Marks (for example, letters, symbols, and colors) for enabling identification may be provided on the bag fixing flange portion 26.

  When characters are provided as marks for identifying the appropriate position of the lid 10 with respect to the base 9 by the user, for example, as shown in FIG. 14, the first cut of the upper surface of the bag fixing flange 26 is performed. A letter “hard” is applied to a position of the notch 20 and the base 9 facing each other in the radial direction. In this case, a letter “soft” is applied to the bag body fixing flange portion 26 at a position facing the second notch 21 on the upper surface thereof in the radial direction of the base body 9. That is, the character “SOFT” is arranged at a position of 90 ° with respect to the character “HARD” with respect to the center of the base 9.

  The character “soft” is obtained when the user rotates the lid 10 and makes the second outside air intake 36 face the character “soft” in the radial direction of the base body 9 as shown in FIG. In addition, it indicates that the items stored in the bag body 2 can be softly compressed (for example, the compression ratio of the futon can be compressed by about 50%). In this case, as shown in FIGS. 11 and 12, the first outside air inlet 43 of the lid body 10 overlaps with the second notch 21 of the base 9 in the radial direction and has a large opening area. At this time, as in the first embodiment, when the air inside the bag body 2 is sucked, the outside air taken in from the first outside air inlet 43 increases, so that the air inside the bag body 2 is sucked. The force is weakened, and the compression rate of the stored items after suction is reduced.

  The character “hard” is stored in the bag 2 when the user rotates the lid 10 so that the second outside air intake 36 faces the character “hard” in the radial direction of the base body 9. This indicates that the stored item can be greatly compressed (for example, the compression ratio of the futon can be compressed by about 70%). In this case, as shown in FIGS. 9 and 10, the first outside air inlet 43 of the lid body 10 overlaps with the first notch 20 of the base 9 in the radial direction and has a small opening area. At this time, as in the first embodiment, when the air inside the bag body 2 is sucked, the outside air taken in from the first outside air inlet 43 is reduced, so that the air inside the bag body 2 is sucked. The force becomes stronger, and the compression rate of the stored items after suction increases.

  As described above, when the characters “hard” and “soft” are applied to the upper surface of the bag body fixing flange portion 26, the user can set the second outdoor air intake port that can set the contents stored in the bag body 2 to a desired compression rate. The position of 36 with respect to the base 9 can be easily grasped, which is preferable.

  In the first embodiment, the shape of the click cutout 24 of the lid regulating wall 23 of the base body 9 is V-shaped as shown in FIG. 3, but is not limited to this shape, and the lid 10 Any shape can be used as long as the click convex portion 42a can be fitted. For example, the shape of the click cutout 24 may be a quadrangular shape as shown in FIG.

  In the first embodiment, the click notch 24 is formed at one end portion of the lid body regulating wall 23 of the base body 9 as shown in FIG. 3, but as shown in FIG. 14, the lid body regulating wall 23 of the base body 9. It may be formed at both ends. In this way, regardless of the position where the lid body 10 is rotated with respect to the base body 9, the click convex portion 42 is fitted into one of the click cutouts 24, 24 of the lid body regulating wall 23. Therefore, when the user rotates the lid 10, a click feeling is easily obtained, which is preferable.

  In the first embodiment, the cut portion 44a formed in the partition wall 44 of the lid 10 is cut out in a V shape from the outside in the radial direction of the lid 10 as shown in FIG. As shown, the lid 10 may be cut out in an L shape from the inside in the radial direction.

  As shown in FIG. 15, the lid body 10 of the compression bag exhaust valve 3 of the second embodiment includes a grip portion 31 b that is gripped when the user rotates the lid body 10. Specifically, the grip portion 31 b is disposed at a position sandwiched in the circumferential direction of the base body mounting wall 31 by the inclined wall portions 40 and 40 of the wall surface body 31 a of the base body mounting wall 31. The grip portion 31b is formed by arranging a plurality of rod-like protrusions extending from the upper edge portion to the lower edge portion of the wall surface main body 31a at a certain interval in the circumferential direction of the base body mounting wall 31. Thereby, when a user picks the grip part 31b and rotates the cover body 10, a finger becomes difficult to slip with respect to the cover body 10, and it becomes easy to rotate the cover body 10.
