Description

  The present invention relates to a foam ejection container that squeezes a body portion of a container body to mix a liquid content contained in the container body with air and eject the foam from a nozzle.

  As a container for storing liquids such as shampoos, body soaps, hand soaps, facial cleansers, etc. A foam ejection container in which a liquid is mixed with air and ejected from a nozzle in the form of foam is often used.

  In such a bubble ejection container, a mixing chamber for mixing the content liquid with air is provided in the discharge flow path of the content liquid, and a foaming member made of, for example, a mesh is incorporated downstream of the mixing chamber, so that the body portion of the container body By compressing the liquid, the foaming member is allowed to pass through the foaming member while mixing the content liquid with air to be foamed and ejected from the nozzle.

  On the other hand, in order to prevent the foam-like content liquid remaining inside the nozzle after use from liquefying over time and dripping from the tip of the nozzle as a foam ejection container as described above, a so-called suck back function is provided. It is known to have it.

  For example, in Patent Document 1, a return flow path that communicates the nozzle and the container main body is provided between the nozzle and the container main body, in addition to the discharge flow path, and the contents from the container main body toward the nozzle are provided in the return flow path. A check valve that restricts the flow of the liquid and allows the flow of the content liquid from the nozzle into the container body, and the content liquid remaining in the nozzle due to the negative pressure generated in the container body when the squeezing is released A bubble jetting container is described in which it is drawn back into the container body through the return channel.

JP 2014-46938 A

  In the conventional bubble ejection container, when the container is turned sideways or upside down when not in use, the content liquid in the container body may leak from the nozzle through the discharge flow path and the return flow path. Therefore, in order to prevent the liquid content from leaking out of the nozzle even when the container is turned sideways or upside down, the flow path between the nozzle and the container body can be closed when the nozzle head is not used by rotating the nozzle head. It is conceivable to have a configuration.

  However, in such a configuration, when the internal pressure in the container body rises due to some factor such as a temperature rise in a state where the flow path between the nozzle and the container body is closed, the return flow path is non-returned by the internal pressure. Since it is closed by the valve, when the nozzle head is rotated during use to open the flow path between the nozzle and the container main body, the content liquid in the container main body is pumped to the discharge flow path by the internal pressure, There was a risk of leakage from the nozzle tip.

  An object of the present invention is to solve such a point, and the object of the present invention is to use the flow path in use even when the flow path is closed between the nozzle and the container body when not in use. An object of the present invention is to provide a foam ejection container in which the content liquid in the container body does not leak from the nozzle to the outside due to internal pressure when is opened.

  The foam ejection container of the present invention has a flexible container body having a content liquid storage space, a distribution port for delivering the content liquid, and a mounting cap attached to the mouth of the container body. An opening / closing lid portion and a nozzle connected to the flow port, and are attached to the mounting cap by screw connection, and the open / close lid portion closes the flow port and an open position that opens the flow port. A mounting head comprising: a nozzle head that can be rotated between; and a partition member having a mixing chamber connected to the flow port, and an air introduction hole and a liquid introduction hole at the bottom of the storage space connected to the mixing chamber. Further has an air passage hole that does not communicate with the flow port, and the air passage hole is closed by the nozzle head in the closed position, and is opened in the open position to communicate the accommodating space with the outside. And

  According to the present invention, in the above-described configuration, it is preferable that the nozzle head further includes a seal tube portion provided coaxially with the opening / closing lid portion, and the seal tube portion closes the air passage hole at the closed position.

The air passage hole is preferably opened.

  In the above configuration, the present invention preferably further includes a check valve that restricts the discharge of air to the outside between the accommodation space and the air passage hole.

  According to the present invention, in the above-described configuration, the check valve is formed in a circular and film shape that extends radially outward from the outer peripheral surface of the cylindrical holding portion that is fixed to the outer peripheral surface of the partition member. It is preferable that a seal film portion that contacts the inner surface of the mounting cap at the outer peripheral edge when the nozzle head is in the open position and separates from the inner surface when the nozzle head is in the closed position is provided.

  According to the present invention, in the above configuration, the mounting cap is provided with a stopper cylinder provided coaxially with the flow port, and two stoppers provided on the outer peripheral surface of the stopper cylinder with a predetermined interval in the circumferential direction. When the nozzle head further includes a convex piece disposed between the stopper pair, and one of the stopper pieces of the stopper pair comes into contact with the convex piece Preferably, the closed position is reached, and the open position is reached when the other stopper piece of the stopper pair comes into contact with the convex piece.

  According to the present invention, in the above configuration, it is preferable that the nozzle head rotates 90 degrees between the closed position and the open position.

Therefore, even when the flow path can be closed between the nozzle and the container body when not in use, the content liquid in the container body leaks out of the nozzle due to internal pressure when the flow path is opened during use. Can be prevented. Further, in the present invention, since air is taken in from an air passage hole provided other than the distribution port for sending out the content liquid, the foam is not drawn into the container again, and the foam quality is deteriorated due to the foam accumulating in the container. Can be prevented.

  Hereinafter, the present invention will be described in detail with reference to the drawings.

  A foam ejection container 1 according to an embodiment of the present invention shown in FIG. 1 is also called a squeeze foamer, and contains various liquid detergents such as shampoos, body soaps, hand soaps, facial cleansers, and hair liquids. The content liquid is ejected in the form of bubbles.

  As shown in FIG. 1, the foam ejection container 1 includes a container body 10. The container body 10 includes a cylindrical mouth portion 11 having an upper opening and an elliptic cylindrical body portion 12 connected to the mouth portion 11, and the inside thereof is an accommodation space S for containing the content liquid. The container body 10 is made of a synthetic resin, and its body part 12 has flexibility. By compressing (squeezing) the body part 12, the storage space S is reduced, and the inside of the container body 10 is added. Can be pressed.

  As shown in FIG. 1, a mounting cap 20 is mounted on the mouth portion 11 of the container body 10. The mounting cap 20 made of resin, for example, has a cylindrical outer peripheral wall 21 that surrounds the mouth portion 11 of the container body 10. The protrusion 11 a provided on the outer peripheral surface of the mouth portion 11 climbs over the locking protrusion 21 a provided on the inner peripheral surface of the outer peripheral wall 21 and engages with the undercut, whereby the mounting cap 20 is attached to the container body 10. It is fixed to the mouth part 11. A seal tube portion 23 is provided coaxially and integrally on the inner side of the outer peripheral wall 21 via a flange portion 22, and the seal tube portion 23 is fitted inside the mouth portion 11, so that the mounting cap 20, the mouth portion 11, The fitting portion is sealed to prevent liquid leakage from the portion.

  Protrusions 11b are provided at the distal end of the mouth portion 11 at intervals in the circumferential direction, and rotation-preventing ribs 21b corresponding to the projections 11b are also provided at intervals inside the outer peripheral wall 21 at intervals in the circumferential direction. Yes. When the mounting cap 20 is fixed to the mouth portion 11, the rotation prevention rib 21b is disposed between the protrusions 11b. As a result, the mounting cap 20 is held against the mouth portion 11.

  In the illustrated case, the mounting cap 20 is fixed to the mouth portion 11 of the container body 10 by undercut engagement. However, the mounting cap 20 is fixed to the mouth portion 11 of the container body 10 by screw connection. It can also be.

  The seal cylinder portion 23 extends further upward through the flange portion 22, and a step portion 24 extending inward in the radial direction is integrally provided at an upper end portion thereof. The inner surface of the step portion 24 facing downward in the figure is a downward step surface 24a formed flat and annular.

  On the inner peripheral edge of the stepped portion 24, a stopper cylinder 25 extending from the inner peripheral edge upward in the figure is integrally provided. The stopper cylinder 25 is formed in a cylindrical shape and is arranged coaxially with the outer peripheral wall 21.

  A distribution cylinder part 26 is integrally provided inside the stopper cylinder part 25. The distribution cylinder part 26 is formed in a cylindrical shape coaxial with the stopper cylinder part 25, and is connected to the inner peripheral surface of the stopper cylinder part 25 at a lower end part 26 e whose diameter is increased in a flange shape. As shown in FIG. 1, a plurality of air passage holes 25 h and 26 h arranged in the circumferential direction are provided on the side surface of the stopper cylinder portion 25 and the lower end portion 26 e in order to introduce air to be described later. Further, the inside of the distribution cylinder portion 26 is a content liquid distribution port 26 a, and the distribution port 26 a communicates with the port 11 of the container body 10, that is, the accommodation space S. Therefore, the content liquid and air in the storage space S of the container body 10 can flow out toward the outside of the mounting cap 20 through the circulation port 26a.

  A nozzle head 30 is attached to the attachment cap 20. For example, the nozzle head 30 made of resin includes a cylindrical lower cover portion 31a having an inner diameter equivalent to the outer peripheral wall 21 of the mounting cap 20, and a cover extending radially inward from the upper end of the lower cover portion 31a. A stepped portion 31b, an upper cover portion 31c extending upward from the inner peripheral end of the cover stepped portion 31b, and a dome-shaped top wall 32 connected to the upper cover portion 31c are formed in a cap shape.

  A double threaded portion 28 is provided on the outer peripheral surface of the outer peripheral wall 21 of the mounting cap 20, and engages with engaging protrusions 33 a and 33 b provided on the inner side of the lower cover portion 31 a of the nozzle head 30.

  As described above, the nozzle head 30 is screwed to the double threaded portion 28 of the mounting cap 20 on the inner peripheral surface of the lower cover portion 31 a and is rotatably mounted on the mounting cap 20.

  With the above configuration, the nozzle head 30 is rotatable with respect to the mounting cap 20, but the rotation range is restricted to an angle range of 90 degrees by the stopper mechanism. The stopper mechanism can be configured as follows, for example.

  As shown in FIG. 2, two pairs of stoppers 29 are provided on the outer peripheral surface of the stopper cylinder portion 25 of the mounting cap 20 so as to be shifted from each other by 180 degrees in the circumferential direction. The stopper pair 29 includes two stopper pieces 29a that are arranged at an interval of about 90 degrees in the circumferential direction. On the other hand, a cylindrical convex piece cylinder portion 34 is integrally provided inside the upper cover portion 31 c of the nozzle head 30. Two convex pieces 35 corresponding to the two pairs of stoppers 29 are integrally provided on the inner peripheral surface of the convex piece cylindrical portion 34. The two convex pieces 35 are provided so as to be shifted from each other by 180 degrees in the circumferential direction, and project from the inner peripheral surface of the convex piece cylindrical portion 34 toward the inside in the radial direction. Each convex piece 35 is disposed within a movement range R between the two stopper pieces 29 a of the corresponding stopper pair 29.

  When the nozzle head 30 rotates with respect to the mounting cap 20, each convex piece 35 moves in the movement range R along the circumferential direction, and when the nozzle head 30 reaches the closed position where it is most tightened with respect to the mounting cap 20. Each convex piece 35 abuts against one stopper piece 29a of the corresponding stopper pair 29, and further rotation is restricted. On the other hand, when the nozzle head 30 is rotated 90 degrees in the loosening direction from the closed position and reaches the open position, each convex piece 35 comes into contact with the other stopper piece 29a of the corresponding stopper pair 29, and that of the nozzle head 30 is reached. The above rotation is restricted.

  With such a configuration, the nozzle head 30 is 90 degrees between the open position shown in FIG. 2 and the closed position shown in FIG. 4 with respect to the mounting cap 20 around the axis of the mouth 11 of the container body 10. It is freely rotatable in the angle range. Since the nozzle head 30 is mounted on the mounting cap 20 by screw connection, the nozzle head 30 moves up and down with respect to the mounting cap 20 when rotated between the closed position and the open position.

  A nozzle 36 is provided integrally with the nozzle head 30. The nozzle 36 is formed in an elliptical cylindrical shape, and is provided above the partition wall 37 provided in the nozzle head 30 so as to protrude to the side facing the upper cover portion 31c. The partition wall 37 is provided with a pair of inflow / outflow holes 38, and the nozzle 36 communicates with the flow port 26 a of the mounting cap 20 through the outflow / inflow holes 38. In the illustrated case, the partition wall 37 is provided with a pair of inflow / outflow holes 38, but the number and shape thereof can be variously changed.

  A cylindrical opening / closing lid 39 is integrally provided on the lower surface of the partition wall 37 of the nozzle head 30. The open / close lid portion 39 is formed in a cylindrical shape having an outer diameter corresponding to the inner diameter of the flow tube portion 26. When the nozzle head 30 is in the closed position, the open / close cover portion 39 is fitted inside the flow tube portion 26 to close the flow port 26a. When the nozzle head 30 is in the open position, the flow port 26a is opened away from the flow port 26a. That is, the nozzle head 30 rotates between a closed position where the open / close lid 39 closes the flow port 26a and an open position where the open / close lid 39 is separated above the flow port 26a and opens the flow port 26a. It is possible.

  A connecting tube portion 41 is provided integrally with the opening / closing lid portion 39 on the inner side of the opening / closing lid portion 39 of the partition wall 37 of the nozzle head 30. A partition member 50 is fixed below the connecting cylinder portion 41. In the case shown in the figure, the partition member 50 is made of resin and is formed in a cylindrical shape having a vertically divided structure, and is fitted and fixed to the connection tube portion 41 at the upper end thereof. Accordingly, when the nozzle head 30 rotates between the open position and the closed position, the partition member 50 rotates together with the nozzle head 30 and moves up and down with respect to the mounting cap 20.

  A hole forming portion 51 is integrally provided at the lower end of the partition member 50, and a mixing chamber 52 is formed in the partition member 50. The hole forming part 51 forms an air introduction hole 53 on the lower end side of the partition member 50. The air introduction hole 53 communicates the mixing chamber 52 with the accommodation space S (inside the container body 10), and the air in the accommodation space S is introduced into the mixing chamber 52 through the air introduction hole 53. On the other hand, a tube 54 extending to the bottom of the container body 10 is connected to the hole forming portion 51 (the lower end of the tube 54 constitutes a liquid introduction hole), and the content liquid in the storage space S is mixed through the tube 54 with the mixing chamber. 52.

  Inside the partition member 50, a pair of foam members 57 are mounted on the upper side (downstream side) of the mixing chamber 52. As these foaming members 57, for example, a structure in which a mesh is fixed to an end face of a ring is used, and the mesh members are fitted and fixed inside the main body portion in a posture in which each mesh is directed to the opposite side. The foam member 57 is not limited to a structure having a ring and a mesh, and for example, materials having various configurations such as a sponge or a porous molded product (sintered body) are used depending on the type of content liquid. be able to. The number of foam members 57 to be installed can be variously changed according to the type of content liquid.

  The upper side of the foaming member 57 in the partition member 50 is a discharge flow path 58 that is continuous with the mixing chamber 52, and a pair of discharge holes are formed in the partition member 50 in order to connect the discharge flow path 58 to the flow port 26a. 59 is provided. In other words, the mixing chamber 52 communicates with the flow port 26 a via the discharge flow path 58 and the discharge hole 59, and further communicates with the nozzle 36 via the flow port 26 a and the inflow / outflow hole 38. The number and shape of the discharge holes 59 provided in the partition member 50 can be variously changed.

  An air introduction path 60 is provided between the outer peripheral surface of the partition member 50 and the stopper cylinder 25 to guide air from the outside when a negative pressure is generated in the container body 10 after the content liquid is ejected. Yes. External air passes through a space between the lower cover portion 31a and the outer peripheral wall 21 as shown by a solid line arrow in FIG. 1, and further to the stopper cylinder portion 25 and the lower end portion 26e of the distribution cylinder portion 26. The air is introduced from the air introduction path 60 into the accommodation space S via the air passage holes 25h and 26h provided.

  The seal cylinder 40 is fitted to the inner peripheral surface of the stopper cylinder 25 and closes the air passage holes 25h and 26h when the nozzle head 30 is in the closed position.

  A check valve 61 is provided in the air introduction path 60. The check valve 61 includes a cylindrical holding portion 61a fitted and fixed to the outer peripheral surface of the partition member 50, and an annular and membrane-like sealing film portion 61b extending radially outward from the outer peripheral surface of the holding portion 61a. Have.

  As shown in FIG. 1, when the nozzle head 30 is in the open position, the seal film portion 61b elastically contacts the downward step surface (inner surface) 24a of the mounting cap 20 from the lower side at the outer peripheral edge thereof. That is, the check valve 61 functions as a check valve when the nozzle head 30 is in the open position, and allows the flow of air and content liquid from the accommodation space S of the container body 10 to the outside through the air introduction path 60. While regulating, it operates so that the flow of the air to the storage space S of the container main body 10 through the air introduction path 60 may be permitted.

  On the other hand, when the nozzle head 30 is in the closed position, as shown in FIG. 3, the check valve 61 moves downward with respect to the mounting cap 20 together with the nozzle head 30, and the outer peripheral edge of the seal film portion 61b faces downward. It leaves | separates from the level | step difference surface 24a, and the non-return valve 61 will be in the state which does not function. In the closed position of the nozzle head 30, the air passage holes 26 h and 25 h are both closed by the lower end surface and the side surface of the seal tube portion 40. Accordingly, the flow of air and contents from the accommodation space S of the container body 10 to the outside via the air introduction path 60 is restricted.

  Further, when the nozzle head 30 is in the air discharge position between the open position and the closed position, as shown in FIG. 5, the outer peripheral edge of the seal film portion 61b is in a state of being separated from the downward step surface 24a and is closed. As with the position, the check valve 61 does not function. The position of the nozzle head 30 at this time is the position shown in FIG. At this air discharge position, the air passage holes 26h and 25h are both open, while the open / close lid 39 still maintains the closed state of the flow port 26a. Therefore, as shown by solid line arrows in FIG. 5, while the air is discharged from the storage space S of the container body 10 to the outside via the air introduction path 60, the leakage of the contents from the circulation port 26a It will be regulated.

  Next, the usage method of the foam ejection container 1 of such a structure is demonstrated.

  As shown in FIG. 1, by setting the nozzle head 30 to the open position, the opening / closing lid 39 is separated above the flow port 26a, the flow port 26a is opened, and the seal film portion 61b of the check valve 61 is removed. The peripheral edge comes into contact with the downward stepped surface 24a of the mounting cap 20, and the foam ejection container 1 is in a usable state in which the liquid content can be ejected by squeezing the squeeze portion 12. When the nozzle head 30 is in the open position, the nozzle 36 is directed in the direction indicated by the two-dot chain line in FIG.

  In a state where the nozzle head 30 is in the open position, the foam-like content liquid can be ejected from the nozzle 36 by squeezing the body 12 of the container body 10. That is, when the body 12 is squeezed, the content liquid stored in the storage space S of the container body 10 is introduced into the mixing chamber 52 through the tube 54. Further, the air in the container body 10 is introduced into the mixing chamber 52 through the air introduction hole 53. Then, the content liquid is mixed with air in the mixing chamber 52 to be foamed and foamed. In addition, the foamed content liquid passes through the foaming member 57 and is discharged from the discharge hole 59 to the flow port 26a through the discharge flow path 58 while being further foamed and foamed. Then, the foam-like content liquid discharged to the circulation port 26 a reaches the nozzle 36 through the outflow / inflow hole 38, and is ejected to the outside from the opening of the nozzle 36.

  When the squeezing of the body part 12 is released after the content liquid is ejected, the body part 12 is restored to its original shape, so that a negative pressure is generated in the container body 10, and the check valve 61 is opened by this negative pressure. Air is drawn into the container body 10 from the outside through the air introduction path 60.

  On the other hand, when not in use, as shown by a two-dot chain line in FIG. 4, the nozzle head 30 is rotated 90 degrees with respect to the mounting cap 20 to a closed position. As a result, as shown in FIG. 3, the opening / closing lid 39 closes the circulation port 26 a, and the communication between the nozzle 36 and the accommodation space S of the container body 10 is blocked. In this closed position, the air passage holes 26 h and 25 h are both closed by the lower end surface and the side surface of the seal tube portion 40. Therefore, the flow of air from the outside to the accommodation space S of the container body 10 via the air introduction path 60 is also restricted. Thereby, the foam ejection container 1 can be made unusable.

  Thus, in the foam ejection container 1 of the present embodiment, the foam ejection container 1 can be made unusable by a simple operation of rotating the nozzle head 30 from the open position to the closed position. Thereby, even if the trunk | drum 12 is squeezed unexpectedly at the time of non-use etc., it can prevent reliably that the content liquid in the container main body 10 leaks outside through the nozzle 36. FIG.

  By the way, as described above, the foam ejection container 1 has a configuration in which the circulation port 26a can be closed by the opening / closing lid portion 39 by setting the nozzle head 30 to the closed position, and therefore the container in a state where the circulation port 26a is closed. When the main body 10 is warmed due to an increase in temperature or the like, the internal pressure in the container main body 10 may increase. However, in the foam ejection container 1 of the present embodiment, the internal pressure can be released to the outside as follows.

  When the nozzle head 30 is rotated from the closed position to the open position, when passing through the air discharge position shown in FIGS. 5 and 6, the seal cylinder portion 40 moves upward, and the air passage holes 26h and 25h are opened. Is done. Accordingly, the storage space S of the container body 10 is communicated to the outside of the container via the air introduction path 60, the air passage holes 26h, 25h, and the like. On the other hand, in this air discharge position, the open / close lid portion 39 still maintains the closed state of the flow port 26a. Therefore, when the nozzle head 30 is rotated from the closed position to the open position for use in the state where the internal pressure of the container body 10 is increased, the path indicated by the solid line arrow in FIG. 5 when passing through the air discharge position. Thus, the internal pressure in the container main body 10 can be released from the air introduction path 60 to the outside. As a result, it is possible to prevent the content liquid stored in the storage space S from being pushed by the internal pressure and leaking outside from the nozzle 36 via the flow port 26a and the like.

  In addition, according to the present embodiment, the mounting cap 20 is provided with the air passage holes 25h and 26h so that air is taken in from the air passage holes 25h and 26h provided separately rather than the circulation port 26a for ejecting the content liquid. did. Thereby, even if the compression of the trunk | drum 12 is cancelled | released after jetting of the content liquid and a negative pressure generate | occur | produces in the container main body 10, a bubble is not drawn in into the container main body 10 from the nozzle 36. FIG. Therefore, bubbles do not accumulate around the mixing chamber 52, and deterioration of the foam quality can be prevented.

  In addition, according to the present embodiment, by providing the check valve 61 on the outer peripheral surface of the partition member 50, the air from the accommodation space S of the container body 10 can be compressed even when the body 12 of the container body 10 is squeezed at the open position. Leakage of air and content liquid to the outside through the introduction path 60 can be prevented.

  Further, according to the present embodiment, the position where one stopper piece 29a of the stopper pair 29 provided on the mounting cap 20 is in contact with the convex piece 35 provided on the nozzle head 30 is set as the closed position, and the other stopper piece 29a is provided. The position in contact with the convex piece 35 is set as the open position. Thereby, the opening 26a and the air passage holes 25h and 26h can be reliably opened and closed with a simple configuration.

  It goes without saying that the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention.

  For example, in the above-described embodiment, the outer peripheral edge of the sealing film portion 61b of the check valve 61 is brought into contact with the downward step surface 24a of the mounting cap 20, but any part that can block the air introduction path 60 is used. The outer peripheral edge of the sealing film 61b may be brought into contact with the other inner surface of the mounting cap 20.

  Moreover, the structure of the air introduction hole 53 provided in the partition member 50, the structure of the check valve 61, and the like can be of various structures as long as they have the function.
