In the discharge container shown in FIG. 1, it is sectional drawing which shows the process in which the movable member pulls in the content inside a nozzle and moves to a open position from a closed position.

  The invention will now be illustrated in more detail with reference to the drawings.

  The discharge container 1 according to an embodiment of the present invention shown in FIG. 1 is also called a squeeze foamer, and includes contents such as various liquid detergents such as shampoo, body soap, hand soap and face wash, and hair setting agents. And the content is discharged in the form of foam.

  As shown in FIGS. 1 and 2, the discharge container 1 includes a container body 10. The container body 10 is provided with a cylindrical opening 11 having an open upper portion and an elliptic cylindrical body 12 connected to the opening 11. The inside is an accommodation space S for accommodating contents. The container body 10 is made of synthetic resin, and the body portion 12 has flexibility, and the volume of the storage space S is reduced by squeezing the body portion 12 and the inside of the container body 10 is expanded. It is possible to press.

  As shown in FIG. 1, a cap C with a nozzle is attached to the mouth 11 of the container body 10. The cap C with a nozzle can be configured to include the mounting cap 20 and the nozzle head 30 as illustrated, for example.

  For example, the mounting cap 20 made of resin has a cylindrical mounting portion 21 surrounding the opening 11 of the container main body 10, and the female screw 21a provided on the inner peripheral surface of the mounting portion 21 is the opening 11 By screwing to the male screw portion 11 a provided on the outer peripheral surface, it is mounted in a state of being screwed and fixed to the opening 11 of the container main body 10. A seal cylinder 22 is coaxially and integrally provided on the inside of the mounting portion 21. By fitting the seal cylinder 22 inside the port 11, the fitting portion between the mounting cap 20 and the port 11 is sealed. And the liquid leakage from the said part is prevented.

  Small protrusions 11b and large protrusions 11c are provided at intervals at the root of the mouth 11 in the circumferential direction, and at the lower end of the mounting portion 21, anti-rotation ribs 21b corresponding to the protrusions 11b and 11c are provided.

When the mounting cap 20 is screwed into the mouth portion 11, the rotation preventing rib 21b is disposed between the small projection 11b and the large projection 11c over the small projection 11b immediately before the screwing end, whereby the mounting cap 20 is 11 is held against rotation.

  In the illustrated case, the mounting portion 21 of the mounting cap 20 is fixed to the opening 11 of the container main body 10 by screw connection, but the mounting portion 21 is fixed to the opening 11 of the container main body 10 by undercutting. It can also be done.

  A stepped portion 23 extending inward in the radial direction is integrally provided on the upper end of the portion of the seal cylinder portion 22 extending upward.

  A stopper cylinder 24 is integrally provided on the inner peripheral edge of the stepped portion 23 and extends upward from the inner peripheral edge in the drawing. The stopper cylinder portion 24 is formed in a cylindrical shape, and is disposed coaxially with the mounting portion 21.

  A flow-through cylinder 25 is integrally provided inside the stopper cylinder 24. The flow cylinder 25 is formed in a cylindrical shape coaxial with the stopper cylinder 24. Further, the flow-through cylindrical portion 25 and the stopper cylindrical portion 24 are integrally connected via an annular intermediate wall 26 whose cross section becomes a crank shape.

  The inner side of the flow pipe 25 is a flow port 25a of the contents, and the flow port 25a communicates with the port 11 of the container body 10, that is, the storage space S. Therefore, the contents and air in the storage space S of the container main body 10 can flow out to the outside of the mounting cap 20 through the flow port 25a, and can be discharged into the outside air or the nozzle 36 described later. The remaining contents can flow from the outside of the mounting cap 20 toward the inside of the housing space S through the flow port 25a. The flow port 25a communicates with the partitioning member 50 and the return flow path 60 described later at one end, and communicates with the outflow / inflow hole 38 described later at the other end.

  The mounting cap 20 is integrally provided with a nozzle mounting cylinder 27 located on the outer peripheral side of the stopper cylinder 24. The nozzle mounting cylindrical portion 27 is formed in a cylindrical shape coaxial with the mounting portion 21 and smaller in diameter than the mounting portion 21, and protrudes upward with respect to the mounting portion 21.

  The nozzle head 30 is mounted to the mounting cap 20. For example, the nozzle head 30 made of resin has a cap shape including a cylindrical cover portion 31 having an outer diameter equal to that of the mounting portion 21 of the mounting cap 20, and a dome-shaped top wall 32 connected to the cover portion 31. Is formed.

  The nozzle head 30 is screwed to the nozzle mounting cylindrical portion 27 of the mounting cap 20 on the inner peripheral surface of the cover portion 31, and is rotatably mounted to the mounting cap 20. As a configuration of the screw connection, for example, a pair of double thread screw portions 28 are provided on the outer peripheral surface of the nozzle mounting cylindrical portion 27 of the mounting cap 20 mutually offset by 180 degrees in the circumferential direction. A pair of projection pairs 33 may be provided on the surface so as to be mutually offset by 180 degrees in the circumferential direction, and these projection pairs 33 may be screwed to the corresponding double thread portions 28 respectively.

  With such a configuration, the nozzle head 30 is attached to the mounting cap 20 by screw connection and is rotatable with respect to the mounting cap 20, but the rotation range thereof is 90 degrees by the stopper mechanism M. It is regulated. The stopper mechanism M can have, for example, the following configuration.

  As shown in FIG. 3, a pair of stopper pairs 29 are provided on the outer peripheral surface of the stopper cylindrical portion 24 of the mounting cap 20 so as to be mutually offset by 180 degrees in the circumferential direction. Each of the stopper pairs 29 includes a first stopper piece 29a and a second stopper piece 29b which are disposed at intervals of about 90 degrees in the circumferential direction. On the other hand, a cylindrical convex piece cylinder 34 is integrally provided inside the cover 31 of the nozzle head 30, and a pair of stoppers 29 is provided on the inner peripheral surface of the convex piece cylinder 34. A corresponding pair of convex pieces 35 are integrally provided. The convex pieces 35 are provided to be mutually offset by 180 degrees in the circumferential direction, and respectively project radially inward from the inner circumferential surface of the convex piece cylinder 34 to form the first stopper pieces 29 a of the corresponding stopper pairs 29. And the second stopper piece 29b.

  When the nozzle head 30 rotates with respect to the mounting cap 20, each convex piece 35 moves in the movement range along the circumferential direction, and when the nozzle head 30 is most tightened against the mounting cap 20, each closed state The convex piece 35 contacts one of the stopper pieces (the first stopper piece 29a in this example) of the corresponding stopper pair 29 so that the further rotation is restricted. On the other hand, when the nozzle head 30 rotates 90 degrees in the loosening direction from the closed state and reaches the open state, the other stopper piece (each of the second stopper pieces 29b in this example) of the corresponding stopper pair 29 has each corresponding convex piece 35 ) To restrict further rotation of the nozzle head 30.

  With such a configuration, the nozzle head 30 is centered on the axial center of the opening 11 of the container body 10 with respect to the mounting cap 20 in the closed state shown by the solid line in FIG. It is pivotable within a 90 degree angle range between. In addition, since the nozzle head 30 is attached to the attachment cap 20 by screw connection, when it rotates between the closed state and the open state, the nozzle head 30 moves up and down with respect to the attachment cap 20. In this example, the nozzle head 30 is located at the lowermost position in the closed state (see FIG. 1) and at the uppermost position in the open state (see FIGS. 5 and 6).

  The nozzle head 30 includes a nozzle 36. The nozzle 36 protrudes from the upper side of the partition wall 37 provided inside the nozzle head 30 to the side of the cover portion 31 (radially outward). The partition wall 37 is provided with a pair of inflow / outflow holes 38 penetrating the inner peripheral surface of the nozzle 36, and the nozzle 36 communicates with the flow port 25 a of the mounting cap 20 via the inflow / outflow holes 38. In the illustrated case, a pair of front and rear outflow / inflow holes 38 are provided in the partition wall 37, but the number and shape thereof can be variously changed.

  In addition, an open / close lid 39 having a top cylindrical shape is integrally provided on the partition wall 37 of the nozzle head 30. The opening and closing lid 39 is disposed between the pair of front and rear outflow holes 38. The open / close lid 39 has an outer diameter corresponding to the inner diameter of the flow cylinder 25. When the nozzle head 30 is closed, the open / close lid 39 is fitted inside the flow cylinder 25 to close the flow port 25a. When 30 is in the open state, the flow opening 25a is opened by being separated upward with respect to the flow opening 25a. That is, the nozzle head 30 rotates between the closed state in which the open / close lid 39 closes the flow port 25a and the open state in which the open / close cover 39 separates above the flow port 25a and opens the flow port 25a. It is possible.

  In addition, the code | symbol 40 is a cylindrical seal part which fits on the internal peripheral surface of the intermediate | middle wall 26, and forms the flow path which goes to the nozzle 36 from the flow opening 25a.

  The partitioning member 50 is mounted on the mounting cap 20. The partitioning member 50 is formed, for example, of a resin material in a cylindrical shape having a circular cross section, and a fitting portion 50a provided at the upper end thereof is fitted and fixed between the stopper tubular portion 24 and the intermediate wall 26 It is supported by 20.

  The hole forming member 51 is fitted and fixed to the lower end of the dividing member 50, and the mixing chamber 52 is formed in the inside of the dividing member 50 by fixing the hole forming member 51. In addition, the hole forming member 51 defines the air introducing hole 53 and the liquid introducing hole 54 on the lower end side of the dividing member 50 together with the dividing member 50. The air introducing hole 53 communicates the mixing chamber 52 with the containing space S (inside of the container body 10), and the air in the containing space S is introduced into the mixing chamber 52 through the air introducing hole 53. On the other hand, a tube 55 extending to the bottom of the container body 10 is connected to the liquid introduction hole 54, and the liquid introduction hole 54 communicates the mixing chamber 52 with the accommodation space S via the tube 55. Therefore, the contents in the accommodation space S are introduced into the mixing chamber 52 through the tube 55 and the liquid introduction hole 54.

  Further, the hole forming member 51 is integrally provided with an umbrella-like body 56 for suppressing the entry of the contents from the air introduction hole 53.

  A foam member 57 is provided in the mixing chamber 52 of the dividing member 50. As this foam member 57, for example, a structure in which a mesh is fixed to the end face of a ring can be used, and in this example, two foam members 57 arranged in an opposite direction are fitted inside the partition member 50. It is fixed. In addition, as the foaming member 57, not only the thing of the structure provided with the ring and the mesh but the thing of various structures can be used according to the kind etc. of a content. In addition, the number of the foam members 57 installed can also be changed variously according to the type of contents and the like.

  The mixing chamber 52 of the dividing member 50 is in communication with the flow port 25 a, and further in communication with the nozzle 36 via the flow port 25 a and the inflow / outlet hole 38.

  A return flow channel 60 connecting the housing space S of the container body 10 and the nozzle 36 is provided outside the partition member 50 separately from the flow channel passing through the inner side of the partition member 50. The flow port 25 a communicates with the storage space S of the container body 10 via the return flow channel 60.

  The return flow passage 60 is provided with a check valve 61. 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 membrane-like seal film portion 61b extending radially outward from the outer peripheral surface of the holding portion 61a. Have.

  The seal film portion 61 b elastically abuts from the lower side to the downward inner surface of the step portion 23 of the mounting cap 20 at the outer peripheral edge thereof. With such a configuration, the check valve 61 blocks the flow of contents and air from the storage space S of the container body 10 to the side of the nozzle 36 (flow port 25a) passing through the return flow channel 60, and It can operate | move so that the flow of the contents and air to the side of the accommodation space S of the container main body 10 which passed through the return flow path 60 from 36 (flow opening 25a) may be permitted.

  Inside the nozzle 36, a movable member 70 movable along the nozzle 36 is provided. The movable member 70 is mounted on the nozzle 36 between the closed position on the distal end side (the position shown by the solid line in FIG. 6) and the open position on the proximal side of the closed position (the position shown by the solid line in FIG. 7). It is provided to be movable along. The movable member 70 can close the content flow path from the accommodation space S side to the discharge port 36 c which is the tip opening of the nozzle 36 in the closed position. More specifically, the movable member 70 in the closed position prevents the content that has passed through the outflow / inflow hole 38 from moving to the discharge port 36c. That is, when the movable member 70 is in the closed position, the content can not be discharged.

  Further, the movable member 70 can open the content flow path from the accommodation space S side to the discharge port 36 c which is the tip opening of the nozzle 36 at the open position. That is, when the movable member 70 is in the open position, the contents having passed through the inflow / outlet hole 38 can be moved to the discharge port 36c. In this case, the contents can pass through the outside of the movable member 70 and the inside of the nozzle 36.

  The movable member 70 has a cylindrical annular portion 70 a and an inner wall 70 b provided inside the annular portion 70 a. The inner wall 70b closes the inside of the annular portion 70a, and forms a pressure receiving surface that receives pressure from air or contents from the accommodation space S when the body 12 is squeezed. The shape of the movable member 70 is not limited to the illustrated example, and can be changed as appropriate. For example, the annular portion 70a is not limited to a cylindrical shape, and may be a cylindrical shape having a cross section other than a circle. The position of the inner wall 70b may be an axial middle portion of the annular portion 70a as shown in the illustrated example, or may be a front end or a rear end. The annular portion 70 a is disposed so as to slide along the inward rib 73 provided on the inner peripheral surface of the nozzle 36.

  A tip side stopper that protrudes radially inward from the inner circumferential surface on the inner circumferential surface on the tip side of the inflow / outlet hole 38 of the nozzle 36 and blocks movement of the movable member 70 to the distal end side from the closed position. The projection 71 can be provided. In addition, the front end side stopper protrusion 71 of this example has a flat annular rear end surface 71a. When the front end surface 70c of the movable member 70 abuts on the rear end surface 71a, the circular opening 71b formed on the rear end surface 71a is closed by the movable member 70. The shape of the opening 71 b is a shape that can be closed in a fluid-tight manner by the movable member 70. In the present example, the inner diameter of the opening 71 b is smaller than the outer diameter of the movable member 70.

  Further, the movable member 70 protrudes radially inward from the inner peripheral surface on the inner peripheral surface on the proximal end side of at least a part of the inflow / outlet hole 38 of the nozzle 36 and moves the movable member 70 closer to the proximal end than the open position. It can be set as composition provided with base end side stopper projection 72 which blocks movement.

  As shown in FIGS. 1 and 4, on the inner peripheral surface of the nozzle 36 on the proximal end side of the distal end side stopper projection 71, it projects radially inward and extends along the axial direction of the nozzle 36 A plurality of inwardly directed ribs 73 are provided. In the present example, the five inward ribs 73 are spaced from each other in the circumferential direction of the nozzle 36, but the number and arrangement of the inward ribs 73 are not limited thereto. A space 74 formed between the inward ribs 73 on the radially outer side of the movable member 70 serves as a flow path for contents. In the nozzle 36 of this example, as shown in FIG. 4, the cross section perpendicular to the axial direction has a track shape in which the rectangular corner portion is curved, but the present invention is not limited thereto. It may be a cylindrical shape.

  Further, as illustrated, the nozzle 36 is provided so as to be insertable into the proximal end nozzle portion 36 a provided integrally with the nozzle head 30 and provided with the proximal end stopper projection 72 and the proximal end nozzle portion 36 a And the tip end nozzle member 36 b having the stopper projection 71. In this case, the distal end nozzle member 36 b is integrally connected to the distal end of the inner cylindrical portion 41 and the inner cylindrical portion 41 inserted in the base end side nozzle portion 36 a and slidably holding the movable member 70. And an outer cylindrical portion 42 whose diameter is enlarged. A distal end side stopper projection 71 is formed on the distal end side of the inner cylindrical portion 41, and an opening 43 communicating with the distal end side portion 38a of the inflow / outlet hole 38 is formed on the proximal end side of the inner cylindrical portion 41. . The opening 43 is also connected to the proximal end portion 38 b of the inflow / outlet hole 38 in this case.

  For example, although the tip nozzle member 36 b can be mainly made of a synthetic resin such as polypropylene (PP), it is not limited thereto, and may be made of, for example, a flexible elastomeric material. When the tip nozzle member 36b is removed for cleaning, the inside of the tip nozzle member 36b can be easily cleaned while being crushed or restored when the tip nozzle member 36b is removed and cleaned.

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

  As shown in FIG. 1, when the discharge container 1 does not discharge the contents during distribution, the nozzle head 30 is closed so that the opening 25a is closed by the open / close lid 39. Thus, the communication between the nozzle 36 and the storage space S of the container body 10 can be shut off, and the discharge container 1 can be disabled. In the present example, when the nozzle head 30 is in the closed state, as shown in FIG. 2, the nozzle 36 is directed in the direction along the major axis direction (long axis) of the barrel 12 of the container main body 10 having an elliptical cross section.

  As described above, in the discharge container 1, the discharge head 1 is put into the unusable state by closing the nozzle head 30, and even if the body 12 is unintentionally squeezed, etc. when not in use, etc. The contents in the container body 10 can be reliably prevented from leaking out through the nozzle 36.

  On the other hand, as shown by a two-dot chain line in FIG. 2, by rotating the nozzle head 30 90 degrees from the closed state, the nozzle head 30 can be opened to make the discharge container 1 usable. . That is, when the nozzle head 30 is opened as shown by a two-dot chain line in FIG. 2, the open / close lid 39 is separated above the flow port 25 a and the flow port 25 a is opened. It becomes a usable state which can discharge the contents by squeezing (squeeze), and when the body 12 is squeezed in this state, the contents are discharged as shown in FIG. In addition, in the state before squeezing the trunk | drum 12, the movable member 70 exists in the open position which contact | abutted or adjoined to the proximal end stopper protrusion 72. As shown in FIG. Further, when the nozzle head 30 is in the open state, as shown in FIG. 2, the nozzle 36 is directed in the direction along the short diameter direction (short axis) of the barrel 12 of the container main body 10 having an elliptical cross section.

  By opening the nozzle head 30 as described above and squeezing the body 12 of the container body 10, it is possible to discharge the foam-like content from the nozzle 36 (see FIG. 5). That is, when the body 12 is squeezed, the contents stored in the storage space S of the container body 10 are introduced into the mixing chamber 52 through the tube 55 and the liquid introduction hole 54 and the air in the container body 10 is The air is introduced into the mixing chamber 52 through the air introduction hole 53, and the contents are mixed with air in the mixing chamber 52 to foam and foam. Further, the foamed content passes through the foam member 57, and moves toward the flow port 25a while being further foamed and formed.

  Then, the foam-like content discharged to the flow port 25a reaches the nozzle 36 through the inflow / outlet hole 38, passes through the outside of the movable member 70, and is externally output from the tip opening (discharge port 36c) of the nozzle 36. It is discharged in the form of foam. At this time, the movable member 70 is pushed by the flow of the foamy content moving in the nozzle 36 through the proximal end portion 38b of the inflow / outlet hole 38 and is separated from the proximal stopper projection 72, and the distal stopper projection Move toward 71. In the process of moving the movable member 70 toward the distal end side stopper projection 71, the contents can pass through the content flow path formed between the inward ribs 73 outside the movable member 70. Therefore, the content passing through the opening 71b is discharged from the discharge port 36c until the movable member 70 abuts on the distal end side stopper projection 71.

  Then, when the front end surface 70c of the movable member 70 abuts on the front end side stopper projection 71, the movable member 70 is stopped at the front end side of the nozzle 36 with respect to the outflow / inflow hole 38 (see FIG. 6). The content passage in the nozzle 36 is closed (the opening 71 b is closed) by the movable member 70 in contact with the distal end side stopper projection 71, and the discharge port 36 c of the nozzle 36 passes through the outflow / inflow hole 38. Movement of the inward melt towards is stopped. As a result, the amount of content discharged from the discharge port 36c is limited by a predetermined amount set in advance. As described above, only a predetermined amount of content is discharged from the discharge port 36 c by a simple single squeeze operation. Therefore, according to the discharge container 1 of the present embodiment, it is possible to discharge a stable amount of content by a simple operation.

  On the other hand, when the squeezing of the body portion 12 is released after the content is discharged, the body portion 12 is restored to the original shape to generate a negative pressure in the container main body 10, and the movable member 70 is pulled by the negative pressure. Then, as shown in FIG. 7, the inside of the nozzle 36 is moved to the initial open position (position in contact with the proximal stopper projection 72). At this time, as shown in FIG. 7, the seal film 61 b is separated from the step 23 by the negative pressure, the check valve 61 is opened, and the air remaining in the nozzle 36 is sucked from the nozzle 36 ( It is drawn into the inside of the accommodation space S of the container main body 10 via the return flow path 60 with the outside air. With this function, which is also called a suck back function, the contents remaining inside the nozzle 36 after discharge can be drawn into the inside of the container body 10 together with air.

  By moving the movable member 70 to a position closer to the proximal side than the distal end side portion 38a of the inflow / outlet hole 38, the movement of the contents drawn from the inside of the nozzle 36 toward the accommodation space S becomes smooth. That is, the movable member 70 hardly resists during suckback.

  It is needless to say that the present invention is not limited to the above embodiment, and various modifications can be made without departing from the scope of the invention. For example, the discharge container of the present invention is not limited to one which discharges the contents in the form of foam (squeeze foamer), for example, a container which discharges the contents in the state (liquid, gel, etc.) without foaming. It is also possible.

  If the movable member 70 is movable along the nozzle 36 between the closed position and the open position, the shapes of the nozzle 36 and the movable member 70 can be variously changed, for example, to be elliptical. is there.

  Further, the cap C with a nozzle is not limited to the configuration having a mechanism for opening and closing the flow port 25 a by screwing the mounting cap 20 and the nozzle head 30, and has a configuration without such an opening and closing mechanism. It can also be done.
