Description

  The present invention relates to a container provided with a pump for taking out liquid contents typified by washing liquid for hair, such as lotion, shampoo, and rinse.

  The basic structure of this type of container with a pump is known from Patent Document 1 previously proposed by the present applicant. Therefore, the container with a pump is composed of a container body, a pump for taking out liquid contents, a partition that divides the inside of the container body into an upper gas phase part and a lower liquid phase part. Yes. The partition body can slide downward following the change in the liquid level in the liquid phase portion, and prevents the contents from being oxidized or denatured by contact with air. A suction pipe reaching the inner bottom of the container body is connected to the suction port of the pump, and the contents can be sucked out from the bottom side portion of the container body. The bottom wall of the container body is formed so as to become lower toward the suction port of the suction pipe.

  Since the container with a pump faces the suction port of the suction pipe to the lowest position of the bottom wall, the contents can be used up without waste until the end. However, if a necessary amount of contents can be taken out at the previous use, even if the remaining amount of contents is less than the amount used for one time, the user is less aware of that. In most cases, the container is emptied only when the contents cannot be removed by the pump. For this reason, it becomes inconvenient until the contents are replenished or a new container with a pump containing the contents is purchased.

  In order to eliminate the above problems, the pump-equipped container is designed to allow the user to recognize that the remaining amount has been reduced by stopping the removal of the contents by the pump while the usage amount for several times remains. Has been proposed (Patent Document 2). There, a floating lid that flattens the top surface of the contents is placed inside the container body, and a stopper provided at the lower part of the suction pipe regulates the downward sliding of the floating lid, and the contents are taken out by the pump. Is stopped and a predetermined amount of contents are left. The stopper is formed in a flange shape and is received by a circular groove formed in the suction pipe. In the state where the removal of the content by the pump is stopped, the shape of the upper surface of the remaining content becomes a mortar shape.

  When removing the contents remaining in the container, loosen and separate the pump screwed and connected to the container body from the container body and force the suction pipe through the pump with the floating lid received by the top cover of the container body. Pulling out, disengaging the stopper and the groove of the suction pipe, the float is positioned below the groove of the suction pipe. By screwing the pump into the container body again in this state, the remaining contents can be sucked with the pump.

JP 2003-267416 A (see paragraph number 0019, FIG. 1) Japanese Unexamined Patent Publication No. 2007-261680 (see paragraph number 0014, FIG. 2)

  According to the container with a pump of Patent Document 2, it is possible to stop the takeout of the content by the pump in a state where a predetermined amount of the content remains, and to allow the user to recognize that the remaining amount of the content has decreased. . However, when removing the contents remaining in the container, it is necessary to separate the pump from the container body, lower the levitation position, and screw the pump into the container body again. Time consuming and annoying. There is also the disadvantage that the contents are exposed to air while the pump is being installed and removed.

  In addition, it is assumed that the contents remain in a mortar shape when the floating lid is received by the stopper, so that the shape of the mortar cannot be maintained when the viscosity of the contents is low, up to the position of the suction port of the suction pipe. The contents are taken out and a sufficient amount of contents cannot be left. In addition, when the container body is stored in an inclined position, the contents may flow so as to cover the suction port of the suction pipe, and the remaining contents may be taken out by the pump at the next use. It may not be possible to reliably leave a sufficient amount of contents.

The purpose of the present invention is to temporarily stop taking out the content by the pump while leaving the content corresponding to the amount used for several times, and let the user recognize that the remaining amount of the content has decreased, In addition, a container with a pump that can make it possible to recognize that it is necessary to replenish the contents or purchase a new one, and to simplify the operation for taking out the contents remaining in the container, thereby quickly taking out the contents. Is to provide.
The object of the present invention is to allow the pump to stop taking out the contents while leaving an appropriate amount of the contents even when the contents are low in viscosity. An object of the present invention is to provide a pump-equipped container that can be widely applied to a wide range of applications.
The object of the present invention is to stop the take-out of the contents by the pump while leaving a proper amount of contents even when the container body is stored in an inclined posture, and from the start of use until the contents are used up. An object of the present invention is to provide a container with a pump that can prevent the contents from coming into contact with air.

  As shown in FIG. 1 and FIG. 2, a container with a pump according to the present invention includes a container main body 1 that contains a liquid content C, and a pump 3 that is mounted on the top of the container main body 1 and takes out the content C. And a suction pipe 15 that is connected to the suction port of the pump 3 and sucks the contents C from the bottom surface side of the container body 1. The container main body 1 includes an upper main chamber 5 that accommodates most of the contents C, and a lower spare chamber 6 that accommodates the preliminary contents C1 corresponding to the amount used for several times. The spare chamber 6 is provided with a delivery tool 26 for reducing the volume of the spare chamber 6 and sending the spare contents C1 to the main chamber 5 side. When the contents C in the main chamber 5 cannot be taken out by the pump 3, the delivery tool 26 is displaced in such a direction that the volume of the auxiliary chamber 6 decreases. Thus, the preliminary contents C1 sent to the main room 5 side are taken out by the pump 3.

  As shown in FIG. 3, a partition body 7 that divides the main chamber 5 into an upper gas phase portion 5 </ b> A and a lower liquid phase portion 5 </ b> B is disposed inside the container body 1. The partition 7 is provided so as to be able to slide down along the suction pipe 15 while following the change in the liquid level of the liquid phase part 5B in the main chamber 5. The preliminary chamber 6 is disposed below the lower sliding limit position of the partition 7.

  As shown in FIG. 1, the preliminary chamber 6 is partitioned by a lower cylindrical wall 1b that opens downward continuously from the main cylindrical wall 1a of the container body 1 and a bottom lid 25 attached to the lower cylindrical wall 1b. The delivery tool 26 is disposed on the inner surface side of the lid 25. The delivery tool 26 includes a valve body 34 that delivers the preliminary contents C1 toward the main chamber 5, and an operation body 38 that faces the outer surface of the preliminary chamber 6 through an operation opening 32 that opens in the bottom cover 25. To do. A restriction structure for restricting the movement of the delivery tool 26 is provided in the vicinity of the operation body 38. Thus, in a state where the restriction function of the restriction structure is released, the delivery tool 26 can be moved in a direction in which the volume of the spare chamber 6 decreases.

  As shown in FIG. 1, the restricting structure includes a pair of engaging bodies 33 and 40 that engage with each other. One of the engaging bodies 33 and 40 is formed on the opening peripheral wall of the operation opening 32, and the other is formed on the lower surface of the delivery tool 26 facing the opening peripheral wall.

  As shown in FIG. 1, a bottom cap 4 that also serves as a stand is rotatably attached to the bottom of the container body 1 so as to cover the outer surfaces of the lower cylinder wall 1 b and the bottom lid 25. As shown in FIG. 11, the restriction structure includes a screw body 48 formed on the operation body 38 and a screw body 49 provided on the inner surface of the bottom cap 4 and meshing with the screw body 48. The delivery tool 26 is held in a non-rotatable manner by a detent structure provided between the bottom lid 25 and the delivery tool 26.

  As shown in FIG. 1, a bottom cap 4 that also serves as a stand is attached to the bottom of the container body 1 so as to cover the outer surfaces of the lower cylinder wall 1 b and the bottom lid 25. A cylindrical boss 44 is provided on the inner surface of the bottom cap 4 to accommodate at least a part of the operation body 38 and protect the operation body 38 from being inadvertently pushed.

  A partition body 7 that divides the main chamber 5 into an upper gas phase portion 5A and a lower liquid phase portion 5B is disposed inside the container body 1. The partition 7 is provided so as to be able to slide down along the suction pipe 15 while following the change in the liquid level of the liquid phase part 5B in the main chamber 5. A boss portion 22 that is in close contact with the outer peripheral surface of the suction pipe 15 is provided in the central portion of the partition 7. The boss portion 22 includes an upper boss 61 and a lower boss 62. The upper boss 61 and the lower boss 62 respectively have tapered seal cylinders 63 and 70 that can be elastically deformed in the radial direction. Seal portions 66 and 72 that contact the outer peripheral surface of the suction pipe 15 are formed at the protruding ends of the seal cylinders 63 and 70.

  In the present invention, the container body 1 is provided with a main chamber 5 that accommodates most of the contents C and a spare chamber 6 that accommodates the spare contents C1 corresponding to the amount used for several times. The spare contents C1 in the spare chamber 6 can be sent to the main chamber 5 by operating the delivery tool 26. Therefore, according to the container with a pump of the present invention, when the content C in the main chamber 5 is completely consumed, the removal of the content by the pump 3 is temporarily stopped, and the remaining amount of the content is reduced. Can be recognized by the user, and can be recognized that the contents need to be replenished or newly purchased.

  In addition, after the take-out of the contents by the pump 3 is stopped, the pre-contents C1 in the pre-chamber 6 is sent to the main chamber 5 side by the delivery tool 26, and a predetermined amount of the pre-content C1 is taken out by the pump. Therefore, the user does not feel inconvenience until the contents are replenished or a new purchase is made. Further, since the spare contents C1 are sent to the main chamber 5 side by operating the delivery tool 26 provided on the spare chamber 6 side, the contents remaining in the container can be reduced compared with the conventional container with a pump of this type. The operation for taking out can be remarkably simplified and the contents can be taken out quickly.

  Furthermore, in the present invention, even when the content has a low viscosity, the removal of the content by the pump 3 can be stopped in a state where an appropriate amount of the content is reliably left, A highly versatile container with a pump that can be widely applied to contents with high viscosity can be obtained. Similarly, even when the container main body 1 is stored in an inclined posture, the extraction of the content by the pump 3 can be stopped in a state where an appropriate amount of the content is reliably left.

  When the partition body 7 that slides down following the liquid level change of the liquid phase portion 5B is disposed inside the container body 1, and the preliminary chamber 6 is disposed below the lower sliding limit position of the partition body 7, With the body 7 lowered to the lower sliding limit position, it is possible to stop taking out the contents by the pump 3. Accordingly, the take-out of the contents by the pump 3 is stopped in a state where the predetermined amount of the spare contents C1 always remains in the spare chamber 6, and the time until the contents are replenished or newly purchased remains. It can be earned by using the spare contents C1. Furthermore, there is also an advantage that the contents 7 can be reliably prevented from touching the air from the start of use until the contents are used up.

  In the state where the preliminary chamber 6 is partitioned by the lower cylindrical wall 1b and the bottom lid 25, the movement of the delivery tool 26 arranged on the inner surface side of the bottom lid 25 is regulated by the regulation structure, and the regulation function is released. Can be moved in the direction in which the volume of the reserve chamber 6 decreases, it is possible to reliably restrict the inadvertent movement of the delivery tool 26. For example, it is possible to restrict the delivery tool 26 that has received a drop impact from moving in a direction that reduces the volume of the spare chamber 6. That is, until the user operates the delivery tool 26 with a clear intention and cancels the regulation function of the regulation structure, the movement of the delivery tool 26 is reliably regulated, and the contents C in the main room 5 are consumed. Until this is done, a predetermined amount of preliminary contents C1 can be reliably left in the preliminary chamber 6.

  When the restricting structure is configured by the engaging body 33 provided on the opening peripheral wall of the operation opening 32 of the bottom lid 25 and the engaging body 40 formed on the lower surface of the sending tool 26 facing the opening peripheral wall, the operation provided on the sending tool 26 is provided. By simply pushing the body 38 toward the inside of the spare chamber 6, the restriction function of the restriction structure can be released. Therefore, it is possible to take out the contents more quickly without the trouble of taking out the contents remaining in the container after the removal of the contents by the pump 3 is stopped. The delivery tool 26 after the regulation function of the regulation structure is released is configured such that the delivery tool 26 gradually rises following the removal of the contents by the pump 3, and the delivery tool 26 is pushed to the limit position all at once. Any form may be used.

  When the bottom cap 4 also serving as a stand is rotatably attached to the bottom of the container body 1 and the restriction structure is configured by the screw body 48 formed on the operation body 38 and the screw body 49 provided on the bottom cap 4, the bottom cap 4 The control function of the control structure can be canceled by rotating the. Therefore, it is not necessary to prepare a tool or a tool for operating the operating body 38, and when necessary, the operating body 38 can be displaced easily in such a direction that the volume of the spare chamber 6 decreases. The non-rotatable structure provided between the bottom lid 25 and the delivery tool 26 holds the delivery tool 26 in a non-rotatable manner. When the bottom cap 4 is rotated, the delivery tool 26 rotates with the bottom cap 4. This is for the purpose of preventing such a situation and reliably releasing the regulation function of the regulation structure.

  When the bottom cap 4 serving also as a stand is attached to the bottom of the container body 1 and at least a part of the operating body 38 is accommodated in the cylindrical boss 44 provided on the inner surface of the bottom cap 4, the operating body is in a normal use state. 38 can be prevented from being pushed in carelessly by the user. In addition, the bottom cap 4 can reliably prevent the operating body 38 from colliding with other objects or being pushed in due to a drop impact, and as a whole, reliability that does not cause functional damage due to misuse or carelessness. A container with a pump excellent in properties can be obtained.

  The boss portion 22 provided in the partition 7 is composed of an upper boss 61 and a lower boss 62, and both the bosses 61 and 62 are tapered seal tubes 63 and 70 and seals provided at the projecting ends of both seal tubes 63 and 70. If comprised by the part 66 * 72, the upper and lower two places of the outer peripheral surface of the suction pipe 15 can be sealed simultaneously. Therefore, the gas phase part 5A and the liquid phase part 5B can be more reliably separated by the partition 7 to prevent the contents C from being exposed to air. Further, since the seal cylinders 63 and 70 of both the bosses 61 and 62 are configured to be elastically deformable in the radial direction, variations in the outer diameter of the suction pipe 15 can be absorbed by the elastic deformation of the seal cylinders 63 and 70. Thus, the partition 7 can be smoothly lowered and slid following the change in the liquid level of the contents C.

(Example) FIG. 1 thru | or FIG. 10 shows the Example of the container with a pump based on this invention. In FIG. 2, the container with a pump is a container main body 1 that contains the liquid contents C, an upper lid 2 that is mounted on the upper part of the container main body 1, a pump 3 that takes out the contents C, and a stand. The bottom cap 4 is attached to the lower part of the head. As shown in FIG. 4, the container body 1 has a large-diameter main cylindrical wall 1a having a circular cross-section that occupies most of the container body 1 and a small-diameter lower cylindrical wall 1b having a circular cross-section formed continuously at the lower end of the main cylindrical wall 1a. And formed. A main chamber 5 that accommodates most of the contents C is defined inside the main cylinder wall 1a, and a reserve chamber 6 that accommodates the reserve contents C1 is defined inside the lower cylinder wall 1b. Inside the container main body 1, a partition 7 that divides the main chamber 5 into an upper gas phase portion 5 </ b> A and a lower liquid phase portion 5 </ b> B is disposed.

  The upper lid 2 also serves as a support for the pump 3 and closes the upper opening of the container body 1 by press-fitting and engaging the upper lid 2 to which the pump 3 is mounted to the container body 1. In FIG. 3, the pump 3 includes a cylinder 9, a piston 10, a suction valve 11 and a discharge valve 12 for opening and closing a suction port and a discharge port of the cylinder 9, and a valve spring 13 for closing and energizing these valves. The structure is the same as that of a conventional pump. A suction pipe 15 is connected to the suction port of the cylinder 9, and a nozzle cap 17 having a nozzle 16 is connected to the discharge port side of the cylinder 9. By repeatedly pushing the nozzle cap 17 against the valve spring 13, the suction valve 11 and the discharge valve 12 are alternately opened and closed, and the contents C stored in the main chamber 5 are passed through the suction pipe 15. It can be sucked into the cylinder 9 and further pressurized and delivered through the nozzle 16.

  The partition body 7 is made of a plastic molded product made of elastic silicone rubber or the like, and includes a sliding wall 20 provided on the peripheral surface, a bottom wall 21, a boss portion 22 provided at the center of the bottom wall 21, and the like. It is formed in a bottomed cylindrical shape that opens upward. On the top and bottom of the sliding wall 20 are provided lip portions 23 that are in close contact with the inner peripheral surface of the main chamber 5, and the upper and lower ends of the boss portion 22 are in close contact with the outer peripheral surface of the suction pipe 15. In this manner, the lip portion 23 and the boss portion 22 are closely guided by the inner peripheral surface of the main chamber 5 and the outer peripheral surface of the suction pipe 15, so that the air in the gas phase portion 5A is the contents in the liquid phase portion 5B. C can be reliably prevented from touching. Between the partition 7 and the cylinder 9, a spring 24 that pushes and urges the partition 7 is disposed.

  The suction pipe 15 is formed by an extrusion method, and its outer diameter dimension varies from 0.1 to 0.15 mm. There is also a variation in the cross-sectional shape of the suction pipe 15. If there is such a variation, for example, when the liquid level of the contents C is lowered, the partition 7 may not be able to smoothly slide down. Alternatively, the content C may be exposed to the air through the gap between the suction pipe 15 and the boss portion 22 or the content C may leak out. In order to eliminate such a problem, the boss portion 22 of the partition 7 is configured as shown in FIGS.

  In FIG. 7, the boss portion 22 includes an upper boss 61 and a lower boss 62. The upper boss 61 is integrally provided with an upper tapered tapered seal cylinder 63 and a mounting cylinder 64 formed continuously at the lower end of the seal cylinder 63. The upper boss 61 can be integrated with the partition 7 by fitting the mounting cylinder 64 to a connecting boss 65 provided on the central upper surface of the bottom wall 21. As shown in FIGS. 8 and 9, the seal cylinder 63 is formed thinner than other portions, and a seal portion 66 is formed at the upper end opening thereof. Reinforcing ribs 67 for retaining the shape of the seal cylinder 63 are formed at regular intervals at five locations around the seal cylinder 63. The reinforcing rib 67 protrudes above the upper end of the seal cylinder 63, and a guide surface 68 for inserting and guiding the suction pipe 15 into the inner surface of the upper end portion is formed in a tapered shape. The lower end of the guide surface 68 is continuous with the seal portion 66. The seal portion 66 is circumscribed in line contact with the outer peripheral surface of the suction pipe 15 to maintain an airtight state, and the diameter dimension thereof is set slightly smaller than the outer diameter dimension (standard dimension) of the suction pipe 15. .

  As shown in FIGS. 7 and 10, the lower bosses 62 are formed on the lower surface side of the bottom wall 21 so as to protrude downward, and are formed at equal intervals at five locations around the seal tube 70. And the shape-retaining reinforcing rib 71. The seal cylinder 70 is formed thinner than other portions, and a seal portion 72 is provided at the lower end opening thereof. The diameter dimension of the seal portion 72 is set to be the same as the diameter dimension of the seal portion 66 of the upper boss 61.

  The seal portion 66 of the upper boss 61 and the seal portion 72 of the lower boss 62 are each subjected to elastic deformation of the seal cylinders 63 and 70 in the diameter increasing direction or the diameter decreasing direction, thereby causing variations in the outer diameter size of the suction pipe 15. Absorb. Therefore, the lowering and sliding of the partition 7 can be performed smoothly when the liquid level of the content C is lowered, and further, the content C is aired through the gap between the suction pipe 15 and the boss portion 22. It is possible to reliably prevent the contents C from leaking out.

  3 until the peripheral edge of the bottom wall 21 is received by the bottom wall 8 of the main chamber 5 from the top end position shown in FIG. Following the change, it is possible to slide down while maintaining the sealing state. The suction port 18 of the suction pipe 15 is located below the bottom wall 21 of the partition 7 at the lower sliding limit position where the partition 7 is lowered and received by the bottom wall 8 of the main chamber 5. Similarly, the preliminary chamber 6 is disposed below the lower sliding limit position of the partition 7. The gas phase portion 5A is always in communication with the atmosphere via a ventilation structure (not shown) provided between the container main body 1 and the upper lid 2.

  The spare room 6 is provided to accommodate the spare contents C1 corresponding to the used amount for several times in a state where the contents C in the main room 5 are consumed. The preliminary chamber 6 is partitioned by the lower cylindrical wall 1b described above and the bottom lid 25 that closes the lower surface opening of the lower cylindrical wall 1b. On the inner surface side of the bottom cover 25, a delivery tool 26 for feeding the preliminary contents C1 to the main chamber 5 side is arranged.

  In FIG. 1, a bottom wall 25 includes a screw cylinder 28 that is externally fitted to the lower cylinder wall 1 b, a lid wall 29 that is formed in an upward projecting manner continuously from the lower end of the screw cylinder 28, and the center of the lid wall 29. It consists of a plastic molded product integrally provided with a boss 30 projecting from the top. Between the inner surface of the screw cylinder 28 and the outer surface of the lower cylinder wall 1b, there is provided a screw structure 31 composed of a male screw and a female screw that mesh with each other, and the bottom wall 25 is fixed to the lower cylinder wall 1b by this screw structure 31. It is. The boss portion 30 has a downwardly tapered operation opening 32 formed in a vertically penetrating manner, and an engaging step portion (engaging body) 33 is formed on the lower peripheral edge of the operation opening 32.

  The delivery tool 26 is formed of a polyethylene plastic molded product integrally provided with a valve body 34 for delivering the preliminary contents C1 toward the main chamber 5 and an operation body 38. The valve body 34 includes a sliding wall 35 that is in close contact with the inner peripheral wall of the lower cylindrical wall 1b, a partition wall 36 that is continuous with the inner surface of the sliding wall 35, and a concave wall that is recessed in a tapered shape at the center of the partition wall 36. 37. The operation body 38 is formed in a rod shape and protrudes downward from the lower surface of the recess wall 37. In the state in which the delivery tool 26 is assembled to the inner surface side of the bottom cover 25, the recessed wall 37 is received in a state of being in close contact with the operation opening 32, and the operation body 38 is almost below the operation opening 32, and accordingly. Projecting to the outer surface of the preliminary chamber 6. On the upper and lower sides of the peripheral surface of the sliding wall 35, lip portions 39 are formed that are in close contact with the inner peripheral wall of the lower cylindrical wall 1b.

  As described above, the delivery tool 26 seals the lower surface opening of the lower cylindrical wall 1b on the inner surface side of the bottom lid 25, substantially divides the preliminary chamber 6 and seals the preliminary contents C1. In order to regulate the movement of the delivery tool 26 toward the main chamber 5 until the contents C stored in the main chamber 5 are consumed by the pump 3, in the vicinity of the operating body 38, specifically the bottom cover 25. A restricting structure is provided between the operation opening 32 and the bottom wall periphery of the recess wall 37. The restriction structure includes the engagement step portion 33 described above and an engagement ring (engagement body) 40 projecting around the bottom wall periphery of the recess wall 37 and engages the outer peripheral surface of the engagement ring 40. It is received by the inner peripheral edge of the stepped portion 33 and the upward movement of the delivery tool 26 is regulated in a normal state. Note that the space between the delivery tool 26 and the bottom cover 25 communicates with the atmosphere through a slit (not shown).

  As shown in FIG. 1, the bottom cap 4 is made of a bottomed cylindrical plastic molded product that opens upward, and a circular engaging rib 43 is formed on the inner surface of a cylindrical wall made of a round cylinder, and is flat. A cylindrical boss 44 for accommodating the operating body 38 is formed at the center of the bottom wall. Engagement ribs 45 are formed on the outer surface of the screw cylinder 28 of the bottom cover 25 in correspondence with the previous engagement ribs 43, and the bottom cap 4 is secured by engaging both the engagement ribs 43. The bottom cover 25 is fixed to the bottom cover 25 so as not to be separated, and covers the outer surface of the lower cylinder wall 1 b and the bottom cover 25. The cylindrical wall in this state is flush with the peripheral surface of the main cylindrical wall 1 a of the container body 1. The cylindrical boss 44 is provided to protect the operating body 38 from being inadvertently pushed in during normal use.

  Next, the usage method of the container with a pump is demonstrated. The partition 7 in the use start state is in the position shown in FIG. When the pump 3 is pushed down by the nozzle cap 17 and the content C is taken out, the content C is sent out from the nozzle 16 by the suction action of the pump 3, and the liquid level of the content C is lowered by an amount corresponding to the delivery amount, At the same time, the partition 7 descends along the inner surface of the main cylindrical wall 1a and the suction pipe 15 following the lowering of the liquid level. As the content C is consumed, the liquid level of the content C gradually decreases. When the content C in the main chamber 5 is consumed, the liquid level of the content C is sucked by the suction pipe 15. The mouth 18 is lowered to the height position. In this state, since the contents cannot be taken out by the pump 3, the user can recognize that the remaining amount of the contents is only the spare contents C1, and further, the user can replenish the contents. Recognize that a new purchase is necessary.

  As described above, after the contents cannot be taken out, the operating body 38 is pushed upward from the lower opening of the cylindrical boss 44 toward the spare chamber 6 to engage as shown in FIG. While the ring 40 is elastically deformed, the engagement state of the pair of engagement bodies 33 and 40 is released. As a result, the delivery tool 26 moves upward to reduce the volume of the preliminary chamber 6, and the liquid level of the preliminary content C 1 is raised above the suction port 18 by that amount. Therefore, the preliminary contents C1 can be taken out by the pump 3. Basically, the operating body 38 is operated by inserting a rod-like body into the inner surface of the cylindrical boss 44. However, if there is no rod-shaped body of an appropriate size, the bottom cap 4 is removed, and the operating body 38 exposed to the outside of the bottom lid 25 is pushed in with fingers to engage the engaging bodies 33 and 40. Can be released.

  The pushing amount of the operating body 38 when releasing the engaged state of the pair of engaging bodies 33, 40 is sufficient if it is at least an amount capable of releasing the engagement of the pair of engaging bodies 33, 40. As shown in FIG. 5, the periphery of the subsequent engagement ring 40 can freely move upward along the operation opening 32, so that the delivery tool 26 is removed as the preliminary contents C <b> 1 are taken out by the pump 3. Can be moved up together with the preliminary contents C1. Finally, as shown by the imaginary line in FIG. 5, the delivery tool 26 is directed upward to a position where the upper lip 39 of the sliding wall 35 is received by the restriction step 46 provided at the upper end of the inner surface of the lower cylindrical wall 1b. To slide. The restricting step portion 46 can receive the delivery tool 26 that has been pushed in excessively and restrict the delivery tool 26 from entering the main chamber 5 side.

  As described above, in the present invention, after the contents C in the main chamber 5 are consumed, the operating body 38 provided in the delivery tool 26 is pushed in to push up the delivery tool 26, thereby Since the liquid level of the preliminary content C1 can be raised, the preliminary content C1 can be quickly taken out with less effort. In addition, a series of operations for taking out the preliminary contents C1 can be remarkably simplified as compared with a conventional container with a pump of this type.

  The assembly of the container with the pump and the filling of the content part C configured as described above are performed as follows. First, as shown in FIG. 6, components other than the bottom cover 25, the delivery body 26, and the bottom cap 4 are assembled to the container body 1. Further, the delivery tool 26 is press-fitted and engaged with the bottom cover 25 to integrate them together. With the container body 1 turned upside down, a predetermined amount of contents C are filled into the container body 1 using the opening of the preliminary chamber 6. Next, the bottom lid 25 is screwed to the lower cylinder wall 1 b to the limit position while the sliding wall 35 of the delivery tool 26 is fitted in the spare chamber 6, and the bottom lid 25 is integrated with the container body 1. Finally, the bottom cap 4 is press-fitted into the bottom lid 25 to integrate the bottom cap 4 with the container body 1. Finally, a protective cap 47 (see FIG. 2) is attached to the outer surface of the nozzle cap 17 to complete the container with a pump. In the same manner as described above, the user can replenish contents.

  If the amount of the contents C when filling the container body 1 is large, a part of the contents C may overflow in the process of screwing the bottom lid 25 into the lower cylinder wall 1b. However, if the partition body 7 is moved and urged by the spring 24, the partition body 7 resists the urging force of the spring 24 as the pressure of the contents C pushed in by the bottom cover 25 increases. Since it moves to the upper cover 2 side to the position which balances the pressure of the content C, it can prevent that a part of the content C overflows.

  FIG. 11 shows another embodiment of a container with a pump according to the present invention. In this case, a restriction structure is configured by a male screw (screw body) 48 formed on the outer peripheral surface of the short-axis operating body 38 and a screw boss (screw body) 49 provided at the center of the inner surface of the bottom cap 4. When the bottom cap 4 is rotated, the engagement between the male screw 48 and the screw boss 49 is released. Therefore, the restraint state of the delivery tool 26 can be released, and the delivery tool 26 can be released to a state in which the delivery tool 26 can be moved upward. In order to prevent the delivery tool 26 from being rotated when the bottom cap 4 is rotated, a detent structure is provided between the delivery tool 26 and the bottom lid 25. The anti-rotation structure includes a rib-like protrusion 50 provided on the lower surface side of the partition wall 36 and an engagement groove 51 provided on the inner surface of the operation opening 32 of the bottom lid 25 corresponding to the protrusion 50. Further, the bottom cap 4 is formed unless a shallow circumferential recess is formed on the joint surface between the bottom cap 4 and the container body 1, and the adhesive tape 52 is pasted around the circumferential recess and the adhesive tape 52 is peeled off and removed. Can not be rotated. Since others are the same as the previous embodiment, the same reference numerals are assigned to the same members, and descriptions thereof are omitted.

  In the above embodiment, after releasing the engaged state of the pair of engaging bodies 33 and 40, the delivery tool 26 is slid upward in conjunction with the take-out operation of the preliminary contents C1 by the pump 3. There is no need. For example, simultaneously with releasing the engagement state of the pair of engagement bodies 33 and 40, the delivery tool 26 is pushed up to the rising limit position defined by the regulation step portion 46, and the preliminary contents C <b> 1 can be taken out by the pump 3. it can. Similarly, the delivery tool 26 can be moved up to the ascent limit position defined by the regulation step portion 46 by the screw feed operation of the male screw 48 and the screw boss 49 described in FIG. Alternatively, the feeding tool 26 may be pushed up little by little by the screw feeding operation of the male screw 48 and the screw boss 49.

  The preliminary chamber 6 can be formed of a hollow body formed separately from the container body 1. For example, the preliminary chamber 6 can be formed of an elbow-shaped hollow body. In that case, the preparatory contents C1 in the spare chamber 6 are pushed by pushing in the delivery tool 26 in the direction (radial direction) intersecting the central axis of the container body 1 along the spare chamber 6 that opens sideways. It can be sent to the main room 5 side. As described above, the moving direction of the delivery tool 26 for reducing the volume of the spare chamber 6 can be changed to any direction of up / down, left / right, and front / rear direction. The volume can be reduced.

  In the container with a pump according to the present invention, the partition 7 can be omitted when the contents C are not easily oxidized or deteriorated. In that case, the space below the suction port 18 becomes the preliminary chamber 6. A restricting structure for restricting the movement of the sending body 7 can be provided between the sending body 7 and the lower cylindrical wall 1b. Depending on the structure of the bottom cover 25, the bottom cap 4 may be omitted, and the bottom cover 25 may also serve as a stand.
