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.

  From the viewpoint of simplifying use by omitting the foaming operation as a container for storing liquids such as shampoos, body soaps, hand soaps, facial cleansers, mouthwashes, etc. A foam ejection container is often used in which the content liquid contained in the container is mixed with air and ejected in a foam form from a nozzle.

  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.

  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.

  In adopting such a configuration, it is desirable to adopt a configuration that can avoid the following problems. That is, when the flow path between the nozzle and the container body is closed, when the internal pressure in the container body rises due to some factor such as a temperature rise, the return flow path is blocked by the check valve In use, when the nozzle head is rotated to open the flow path between the nozzle and the container body, the content liquid in the container body is pumped to the discharge flow path by internal pressure and leaks from the tip of the nozzle to the outside. There is a risk of getting out.

  Therefore, as a result of diligent research, the inventor came up with the following configuration. That is, the nozzle head is configured to be movable up and down with respect to the mounting cap mounted on the mouth portion in accordance with the rotation operation, and the partition member that has the mixing chamber inside and holds the check valve is provided at the upper portion thereof. The nozzle head is fixed to the nozzle head, and when the nozzle head and the partition member move upward, the flow path between the nozzle and the container body is opened and the check valve is seated on the inner surface of the mounting cap.

  However, it has been found that such a configuration can cause the following problems. That is, when the partition member receives a load from the side during distribution or boxing, there is a possibility that the nozzle head and the upper portion of the partition member are not fixed. Moreover, when the check valve is inclined and becomes familiar by receiving a load from the side, the sealing performance with the mounting cap is deteriorated, and there is a possibility that normal discharge cannot be performed. Furthermore, there is a concern about the occurrence of breakage due to deformation of the fixed portion between the nozzle head and the partition member due to such a load.

  The present invention has been developed to solve such a problem. The object of the present invention is to provide a partition member for a mixing chamber even when the flow path can be closed between the nozzle and the container body when not in use.

And the like, and 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.

  A protrusion (not shown) is provided at the distal end of the mouth portion 11 with a gap in the circumferential direction, and a detent rib (not shown) corresponding to the protrusion is also provided on the inner side of the outer peripheral wall 21 with a gap in the circumferential direction. It is provided free of charge. When the mounting cap 20 is fixed to the mouth portion 11, the detent rib is inserted between the protrusions. 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 via the flange portion 22, and a step portion 24 extending inward in the radial direction is integrally provided at the upper end 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 the lower end part whose diameter is enlarged in a flange shape. Further, a reduced diameter portion 26 a is provided at the upper end of the flow tube portion 26. The inside of the reduced diameter portion 26 a of the flow tube portion 26 is a content liquid flow port 26 b, and this flow port 26 b communicates with the mouth 11, that is, the accommodation space S of the container body 10. Therefore, the liquid and air in the storage space S of the container body 10 can flow out of the mounting cap 20 through the circulation port 26b, and can enter the outside air or the nozzle 35 described later. The remaining content liquid can flow into the housing space S from the outside of the mounting cap 20 through the circulation port 26b.

  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.

  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, two convex pieces 34 corresponding to the two pairs of stoppers 29 are integrally provided on the inner peripheral surface of the upper cover portion 31 c of the nozzle head 30. The two convex pieces 34 are provided so as to be shifted from each other by 180 degrees in the circumferential direction, and project from the inner circumferential surface of the upper cover portion 31c toward the radially inner side. Each convex piece 34 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 34 moves in the movement range R along the circumferential direction, and the nozzle head 30 is tightened most with respect to the mounting cap 20 as shown in FIG. 3. When in the closed position, each convex piece 34 comes into contact with 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 to reach the open position, each convex piece 34 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. 1 and the closed position shown in FIG. 3 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 35 is provided integrally with the nozzle head 30. The nozzle 35 is formed in an elliptical cylindrical shape, and is provided so as to protrude laterally above the partition wall 36 provided in the nozzle head 30. The partition wall 36 is provided with a pair of outflow / inflow holes 37, and the nozzle 35 communicates with the flow port 26 b of the mounting cap 20 through the outflow / inflow holes 37.

  A cylindrical opening / closing lid portion 38 is integrally provided on the lower surface of the partition wall 36 of the nozzle head 30. The open / close lid portion 38 is formed in a cylindrical shape having an outer diameter corresponding to the inner diameter of the reduced diameter portion 26 a of the flow cylinder portion 26, and the inner side of the reduced diameter portion 26 a of the flow tube portion 26 when the nozzle head 30 is in the closed position. When the nozzle head 30 is set to the open position, the flow port 26b is opened away from the flow port 26b. That is, the nozzle head 30 rotates between a closed position where the opening / closing lid portion 38 closes the circulation port 26b and an open position where the opening / closing lid portion 38 is separated above the circulation port 26b and opens the circulation port 26b. It is possible.

  A connecting tube portion 40 is provided integrally with the opening / closing lid portion 38 on the inner side of the opening / closing lid portion 38 of the partition wall 36 of the nozzle head 30. A partition member 50 is fixed below the connecting tube portion 40. 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 connecting tube portion 40 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 cylindrical 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. A tube 54 extending to the bottom of the container body 10 is connected to the hole forming portion 51, and the content liquid in the storage space S is passed through the tube 54 (the inner peripheral surface of the upper end of the tube 54 is a liquid introduction hole of the partition member 50. And is introduced into the mixing chamber 52. The air in the accommodation space S is introduced into the mixing chamber 52 through the air introduction hole 53 formed in the gap between the tube 54 and the hole forming portion 51.

  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 26b. 59 is provided. That is, the mixing chamber 52 communicates with the flow port 26 b via the discharge flow path 58 and the discharge hole 59, and further communicates with the nozzle 35 via the flow port 26 b and the inflow / outflow hole 37. The number and shape of the discharge holes 59 provided in the partition member 50 can be variously changed.

  Between the outer peripheral surface of the partition member 50 and the stopper cylinder 25, the content liquid remaining in the nozzle 35 together with the air when the negative pressure is generated in the container body 10 after the content liquid is ejected is contained in the accommodation space S. A return flow path 60 is provided to guide to

  The seal tube portion 39 is in close contact with the outer peripheral surface of the flow tube portion 26 and seals between the seal tube portion 39 and the flow tube portion 26 regardless of the vertical movement of the nozzle head 30.

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

  On the lower side of the check valve 61 in the peripheral wall portion of the partition member 50, a support portion 62 extending radially outward is integrally provided. The support portion 62 is mounted when the outer peripheral side end is close to or in contact with the inner peripheral surface of the seal cylinder portion 23 of the mounting cap 20, so that the foam ejection container 1 is in the horizontal posture at least in the closed position. The cap 20 abuts on the inner peripheral surface of the seal cylinder portion 23. FIG. 2 shows a plan view of the support portion 62 of the partition member 50. As shown in FIG. 2, the support portion 62 includes a plurality of (four in this example) arms 62 a that are arranged at intervals in the circumferential direction and extend radially outward. The upper ends of the ring bodies 62b are connected to the radially outer ends of the plurality of arms 62a. The ring body 62 b has a cylindrical shape extending along the axial direction of the inner peripheral surface of the seal cylinder portion 23 of the mounting cap 20.

  As shown in FIG. 1, when the nozzle head 30 is in the open position, the seal film portion 61 b of the check valve 61 is elastic from the lower side to the downward step surface (inner surface) 24 a of the mounting cap 20 at the outer peripheral edge thereof. Abut. That is, the check valve 61 functions as a check valve when the nozzle head 30 is in the open position, and the clearance between the housing space S of the container body 10 and the arms 62 a of the support portion 62 and the return flow path 60. The flow of air to the circulation port 26b through the flow path 26b and the contents of liquid and air to the accommodation space S of the container body 10 through the gaps between the return flow path 60 and the arms 62a of the support 62 are performed. Operates to allow flow.

  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. However, in the closed position of the nozzle head 30, the circulation port 26 b is closed by the opening / closing lid portion 38. Accordingly, the flow of the content liquid and the air from the accommodation space S of the container body 10 to the nozzles 35 via the gaps between the plurality of arms 62 a of the support portion 62 and the return flow path 60 is restricted.

  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 portion 38 is separated above the flow port 26b, the flow port 26b 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.

  With the nozzle head 30 in the open position, the foamed liquid content can be ejected from the nozzle 35 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. Further, the foamed content liquid passes through the foaming member 57 and is discharged from the discharge hole 59 to the flow port 26b through the discharge channel 58 while being further foamed and foamed. Then, the foam-like content liquid discharged to the circulation port 26 b reaches the nozzle 35 through the outflow / inflow hole 37, and is ejected to the outside from the opening of the nozzle 35.

  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. The content liquid remaining inside the nozzle 35 is drawn into the inside of the container body 10 together with the air (outside air) sucked from the nozzle 35 through the gaps between the return flow path 60 and the arms 62a of the support portion 62. By such a function, also called a suck back function, the content liquid remaining inside the nozzle 35 after the ejection is drawn into the container body 10 together with the air, and the content liquid hangs down from the opening of the nozzle 35 to the outside. Can be prevented.

  On the other hand, when not in use, as shown in FIG. 3, the nozzle head 30 is rotated 90 degrees with respect to the mounting cap 20 to the closed position. As a result, the opening / closing lid 38 closes the circulation port 26b, and the communication between the nozzle 35 and the accommodation space S of the container body 10 is blocked. Thereby, the foam ejection container 1 can be made unusable. When the nozzle head 30 is in the closed position, the nozzle 35 is directed in a direction along the major axis of the trunk 12 of the container body 10 having an elliptical cross section.

  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 35. FIG.

  By the way, as described above, the foam ejection container 1 is configured such that the circulation port 26b can be closed by the opening / closing lid portion 38 by setting the nozzle head 30 to the closed position, and therefore the container with the circulation port 26b 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.

  That is, when the nozzle head 30 is rotated from the open position toward the closed position, 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 is mounted. Apart from the downward stepped surface 24 a of the cap 20, the accommodation space S of the container body 10 is communicated with the circulation port 26 b through the return channel 60. Thereby, even when the nozzle head 30 is rotated from the closed position to the open position for use in the state where the internal pressure in the container body 10 is increased, the nozzle head 30 is moved from the closed position to the open position. The opening / closing lid portion 38 is separated above the flow port 26b, the flow port 26b is slightly opened, and the outer peripheral edge of the seal film portion 61b of the check valve 61 is separated from the downward step surface 24a of the mounting cap 20. Thus, the internal pressure in the container body 10 can be released from the return channel 60 to the outside. Therefore, even if the nozzle head 30 is rotated from the closed position to the open position in the state where the internal pressure in the container body 10 is increased, the internal pressure in the container body 10 is released from the return channel 60 to the outside. It is possible to prevent the internal solution stored in S from being pushed by the internal pressure and pumped to the nozzle 35 through the mixing chamber 52, the discharge flow path 58, the discharge hole 59 and the flow port 26b, and leaking out from the nozzle 35. .

  On the other hand, when the foam ejection container 1 is put into the use state again, the foam ejection container 1 can be switched to the usable state by a simple operation of simply rotating the nozzle head 30 from the closed position to the open position. it can. At this time, when the nozzle head 30 reaches from the closed position to the open position, as shown in FIG. 1, the outer peripheral edge of the seal film portion 61b of the check valve 61 comes into contact with the downward step surface 24a of the mounting cap 20, and the container The check valve 61 regulates the escape of the pressure in the main body 10 from the return flow path 60 to the outside. Therefore, the content liquid accommodated in the accommodating space S by the compression of the body portion 12 is pumped to the nozzle 35 through the mixing chamber 52, the discharge channel 58, the discharge hole 59, and the circulation port 26b, and is externally foamed from the nozzle 35. Can be ejected.

  Such a foam ejection container 1 is in the state shown in FIG. 3 when not in use, particularly during distribution or packaging, but when the foam ejection container 1 is in a lateral orientation at this time, it is partitioned by gravity. A lateral load acts on the member 50. Here, when the partition member 50 is supported only at the upper end thereof, the partition member 50 is inclined by the action of the load, and further, the partition member 50 may be detached from the connection tube portion 40 of the nozzle head 30 or a check valve. 61 may incline and become familiar, resulting in a problem that sealing performance with the mounting cap 20 is deteriorated and normal ejection cannot be performed. However, in the present embodiment, since the partition member 50 is provided with the support portion 62, when the bubble ejection container 1 is in the horizontal orientation at the closed position of the nozzle head 30, the partition member 50 is moved via the support portion 62. It can be supported by the inner peripheral surface of the seal cylinder portion 23 of the mounting cap 20. Therefore, as described above, even when the flow path can be closed between the nozzle 35 and the container body 10 when not in use, the partition member 50 is not detached from the nozzle head 30, and the check valve 61 is not used. The sealing performance can be maintained well, and furthermore, the occurrence of breakage due to deformation of the fixed portion of the partition member 50 can be prevented.

  Another embodiment of the present invention may be configured as shown in FIG.
