Description

  The present invention relates to a discharge container.

As a discharge container, for example, as shown in Patent Document 1 below, a container main body in which contents are stored, a top cylindrical mounting cap mounted on the mouth of the container main body, and an upward biasing state on the mounting cap A pump having a stem penetrating downward, and a pressing head attached to the upper end of the stem and having a discharge hole. The pump includes a piston with which the stem is linked, and a piston vertically A cylinder having a slidably fitted cylinder is known.
In this discharge container, the piston can be moved downward with respect to the cylinder by moving the stem downward by pressing the pressing head, so that the contents in the cylinder are allowed to flow into the stem and then through the discharge hole. Can be discharged outside.

  By the way, generally, when this type of discharge container is not used, the pressing head and the stem are fixed at the lowered end position. For example, in the above discharge container, a screw cylinder portion for screwing the pressing head at the lower end position is attached to the upper end portion of the cylinder. Thereby, when not in use, both the pressing head and the stem are fixed at the lowered end position, and the upward movement is restricted.

JP 2001-300367 A

As described above, since the pressing head and the stem are fixed at the lowered position when not in use, when used, the pressing head is rotated around the container axis with respect to the screw cylinder, and the screw cylinder It is necessary to release the screwing and move the pressing head and stem upward.
However, with the rotation of the pressing head, there is a possibility that the screw cylinder and the cylinder rotate together with the pressing head. Therefore, for example, depending on the balance between the tightening torque of the mounting cap with respect to the mouth of the container body and the rotational torque of the pressing head and the cylinder, the mounting cap may also rotate together with the cylinder and the mounting cap may come off from the mouth. . Specifically, when the rotational torque of the pressing head and the cylinder is equal to or higher than the tightening torque of the mounting cap with respect to the mouth of the container body, the mounting cap is likely to come off from the mouth.

  The present invention has been made in view of such circumstances, and an object of the present invention is to prevent the rotation of the mounting cap by preventing the cylinder from rotating together, and the pressing head and stem to the cylinder. An object of the present invention is to provide a discharge container that can be reliably rotated to improve operability at the start of use.

In order to achieve the above object, the present invention provides the following means.
(1) A discharge container according to the present invention includes a container main body in which contents are stored, a top cylindrical mounting cap mounted on a mouth of the container main body, and an upward biasing state on the mounting cap. A pump having a stem penetrating downward, and a pressing head attached to an upper end of the stem and having a discharge hole, the pump being provided with a mouth of the container body by the attachment cap A cylinder which is held in a state of being inserted into the part and has the stem standing upward on the inside thereof, a piston which is linked to the stem and is fitted in the cylinder so as to be vertically slidable, while being mounted on the upper end of the cylinder, the press head located at the lowered end position is screwed, and a regulation cylinder for regulating the upward movement of the press head and the stem, the cylinder, With tubular sealing that fits inside the mouth of the serial container body is formed, it engages with the first engagement portion formed on the inner peripheral surface of the mouth portion of the container body, the container body A second engagement portion that restricts movement of the cylinder in the circumferential direction relative to the mouth portion is formed, and the second engagement portion is formed on the outer peripheral surface of the seal cylinder .

  According to the present invention, when starting to use, by rotating the pressing head around the container axis, the pressing head can be moved in the circumferential direction with respect to the regulating cylinder to release the screwing. As a result, the pressing head can be detached from the restriction cylinder, and the stem and the pressing head can be moved upward using the upward biasing force with respect to the stem. As a result, the pressing head can be shifted to a state where it can be pressed, and thereafter, the contents can be discharged.

  In particular, the second engagement portion on the cylinder side is engaged with the first engagement portion on the mouth side of the container body, and the movement of the cylinder in the circumferential direction with respect to the mouth portion of the container body is restricted. Are combined so that they cannot rotate. Therefore, when the pressing head positioned at the descending end position is rotated around the container axis, even if the regulating cylinder and the cylinder try to rotate together with the pressing head, this co-rotation can be effectively prevented. . Therefore, since the mounting cap does not rotate together, it is possible to prevent the mounting cap from being detached from the mouth portion of the container body. Furthermore, since the pressing head and the stem can be appropriately rotated around the container axis with respect to the regulation cylinder, the pressing head and the stem can be quickly moved upward, improving the operability at the start of use, The contents can be discharged quickly.

Furthermore, since the second engaging portion is formed in the seal cylinder that seals the mouth portion of the container body, it is necessary to separately provide a sealing member such as a packing that seals between the cylinder and the mouth portion of the container body. Absent. Accordingly, the cost can be reduced and the configuration can be simplified.

(2) The first engaging portion is open above the mouth portion of the container body, and is opened above the mouth portion of the container body, and from one side along the circumferential direction to the other side. And a guide groove portion that is gradually extended downward and is connected to the longitudinal groove portion.

In this case, when the cylinder is combined with the mouth portion of the container body, for example, the second engaging portion formed on the cylinder side is aligned with the guide groove portion of the first engaging portion formed on the mouth side. After that, the mounting cap is screwed into the mouth portion together with the cylinder, so that the second engaging portion is moved in the circumferential direction along the guide groove portion and finally guided into the vertical groove portion. Can be easily and reliably engaged.
As described above, since the screwing is used, the mounting operation of the pump to the mouth portion and the engaging operation between the first engaging portion and the second engaging portion can be smoothly performed without using excessive force. In addition to being able to do it, it is easy to do both operations reliably.

  According to the present invention, the rotation of the mounting cap can be prevented by preventing the cylinder from rotating together, and the operability at the start of use is improved by reliably rotating the pressing head and stem relative to the cylinder. In addition, the contents can be quickly discharged.

Is formed. Thereby, the regulation cylinder 12 is integrally attached to the cylinder 10 in a state in which the regulation cylinder 12 is prevented from rotating with respect to the cylinder 10. However, the structure of the rotation stopper is not limited to the above case.

  As shown in FIGS. 1 and 2, not only the stem 6, piston 11, piston guide 13, valve member 14, and coil spring 15, but also the stem 6 and the pressing head 5 are lowered into the cylinder 10. When positioned at the position P1 (see FIG. 1), a seal cylinder portion 30 that closes the air introduction hole 20 of the cylinder 10 is disposed.

  The seal cylinder part 30 is inserted into the screw cylinder 12b of the restriction cylinder 12, and a closed cylinder part 31 that is slidably fitted into the cylinder 10 is formed at the lower end part. When the stem 6 and the push-down head 5 are located at the rising end position P2 (see FIG. 2), the closed cylinder portion 31 is located between the screw cylinder 12b and the air introduction hole 20 in the cylinder 10. It is in contact with the peripheral surface. On the other hand, in the state where the stem 6 and the pressing head 5 are positioned at the descending end position P1 and the pressing head 5 is screwed to the restriction cylinder 12 (see FIG. 1), the closing cylinder portion 31 is in the air of the cylinder 10. The introduction hole 20 is closed.

  In the illustrated example, seal portions 31 a that bulge outward in the radial direction are formed at the upper end portion and the lower end portion of the closed cylinder portion 31. In the state where the pressing head 5 is screwed to the restriction cylinder 12, the air introduction hole 20 is closed by being positioned between the seal parts 31 a of the closing cylinder part 31.

  The stem 6 is erected upward in the cylinder 10 in a state where the stem 6 is inserted into the seal cylinder portion 30 so as to be movable up and down. At this time, between the outer peripheral surface of the stem 6 and the inner peripheral surface of the seal cylinder portion 30, a communication path R (the outer periphery of the stem 6) that communicates the outside and the inner peripheral surface side of the outer cylinder 40 of the piston 11 described later. A gap in the radial direction between the surface and the inner peripheral surface of the seal cylinder portion 30 and a gap for taking outside air into the container body 2 is formed.

The lower end portion side of the stem 6 is formed in a double cylindrical shape by an outer cylindrical portion 6A having a larger diameter than the other portions and an inner cylindrical portion 6B disposed on the radially inner side of the outer cylindrical portion 6A. Yes.
The inner cylinder portion 6B has an upper end portion formed integrally with the inner peripheral surface of the stem 6, and a lower end portion projecting downward from the outer cylinder portion 6A. An annular gap is formed between the outer cylinder part 6A and the inner cylinder part 6B. In addition, a plurality of introduction grooves 35 for introducing the contents into the stem 6 are formed at intervals in the circumferential direction in a portion of the inner cylinder portion 6B located on the radially inner side of the outer cylinder portion 6A.

The piston 11 includes an outer cylinder 40 in which a seal portion 40 a that is in sliding contact with the inner peripheral surface of the cylinder 10 is formed, an inner cylinder 41 that is disposed on the radially inner side of the outer cylinder 40, an outer cylinder 40, and an inner cylinder 41. And an annular coupling portion 42 that couples the entire circumference.
In the outer cylinder 40, a lower seal portion 40b that is in sliding contact with the inner peripheral surface of the cylinder 10 is formed in a portion located below the seal portion 40a, similarly to the seal portion 40a. The seal portion 40a and the lower seal portion 40b are separately formed on the upper end portion and the lower end portion of the outer cylinder 40, and bulge outward in the radial direction. The connecting portion 42 connects the intermediate portions located between the upper end portion and the lower end portion of each of the outer cylinder 40 and the inner cylinder 41.
The lower end portion of the outer cylinder portion 6A in the stem 6 is externally fitted to the inner cylinder 41 so as to be slidable up and down. Further, the lower seal portion 40b described above is not essential, and only the seal portion 40a may be formed.

  By the way, when the stem 6 and the pressing head 5 are located at the rising end position P2 (see FIG. 2), the air introduction hole 20 is formed in a portion of the outer peripheral surface of the outer cylinder 40 located below the seal portion 40a. Opposing in the radial direction. In the illustrated example, the air introduction hole 20 faces the outer peripheral surface of the intermediate portion of the outer cylinder 40 in the radial direction. That is, the air introduction hole 20 is closed by being positioned between the seal portion 40a and the lower seal portion 40b. Further, when the stem 6 and the pressing head 5 are positioned at the rising end position P2, the upper end edge of the outer cylinder 40 and the lower end edge of the closed cylinder portion 31 in the seal cylinder 10b are in contact with each other.

The piston guide 13 includes a guide main body 13A attached from below to the lower end portion of the inner cylindrical portion 6B in the stem 6, and a top-cylindrical guide cylinder 13B formed integrally with the guide main body 13A. ing.
13 A of guide main bodies are mounted | worn with respect to the lower end part of the inner side cylinder part 6B so that this inner side cylinder part 6B may be inserted | pinched from the both sides of radial direction, and the lower end opening of the inner side cylinder part 6B is plugged up. The guide tube 13B is formed so as to expand outward in the radial direction and extend downward. On the outer peripheral surface of the guide tube 13B, a plurality of proximity protrusions 45 that are close to the inner peripheral surface of the cylinder 10 are formed at intervals in the circumferential direction.

  The contents pass through a gap formed between the adjacent protrusions 45 adjacent in the circumferential direction. Further, the above-described coil spring 15 is disposed inside the guide tube 13B. At this time, the upper end portion of the coil spring 15 is in contact with the top wall portion of the guide tube 13B from below. When the stem 6 is restored and moved upward after the contents are discharged, the top wall portion of the guide cylinder 13B engages with the lower end of the inner cylinder 41 of the piston 11, and the piston 11 is restored and moved upward. .

  The valve member 14 is a check valve that keeps the lower end opening of the cylinder 10 closed when the cylinder 10 is pressurized, and opens the lower end opening of the cylinder 10 when the pressure inside the cylinder 10 is reduced. This restricts the contents in the cylinder 10 from returning from the lower end opening of the cylinder 10 to the container body 2 when the cylinder 10 is pressurized, and the contents in the container body 2 when the cylinder 10 is depressurized. Can flow into the cylinder 10 from the lower end opening of the cylinder 10.

The pressing head 5 includes a fitting cylinder 50 fitted in the upper end portion of the stem 6, a discharge cylinder 51 that protrudes radially outward from the fitting cylinder 50, and has a discharge hole 5a formed at the tip thereof. And a screwed tube 52 surrounding the joint tube 50 from the outside in the radial direction.
The pressing head 5 and the stem 6 are integrally connected by fitting with the fitting cylinder 50. The discharge cylinder 51 penetrates the threaded cylinder 52 in the radial direction, and the inside thereof communicates with the inside of the stem 6 through the inside of the fitting cylinder 50. Thereby, the discharge hole 5a and the inside of the stem 6 communicate. The screwing cylinder 52 can be screwed to the screw cylinder 12b of the restriction cylinder 12 when the pressing head 5 is located at the lower end position P1 (see FIG. 1).

By the way, in this embodiment, the container main body 2 and the cylinder 10 are combined with the container axis O as a center so as not to be relatively rotatable.
Specifically, as shown in FIGS. 3 and 4, an engagement recess (first engagement portion) 60 is formed on the inner peripheral surface of the mouth portion 2 a of the container body 2, and the seal cylinder 10 b in the cylinder 10 is formed. An engagement convex portion (second engagement portion) 61 that engages with the engagement concave portion 60 and restricts the movement of the cylinder 10 in the circumferential direction with respect to the mouth portion 2a of the container body 2 is formed on the outer peripheral surface. Yes.

  In the illustrated example, a plurality of engaging recesses 60 are formed at intervals in the circumferential direction. As shown in FIG. 5, each of these engagement recesses 60 opens above the mouth portion 2 a of the container body 2 and above the mouth portion 2 a of the container body 2, and extends along the circumferential direction. And a guide groove portion 60b that is connected to the longitudinal groove portion 60a while gradually extending downward in accordance with the rotation direction T from the one side (the loose side) toward the other side (the tightening side). Note that the longitudinal groove 60a extends below the guide groove 60b.

  On the other hand, as shown in FIGS. 3, 4 and 6, the engaging convex portion 61 is formed in a vertical rib shape projecting radially outward from the outer peripheral surface of the seal cylinder 10b, and is formed in the vertical groove portion 60a. The vertical groove portion 60a is engaged over the entire length. At this time, the engaging convex portion 61 is formed so that the amount of protrusion outward in the radial direction gradually decreases as it goes in the rotational direction T.

(Use of discharge container)
Next, the case where the discharge container 1 configured as described above is used will be described.
First, when the use is started, the pressing head 5 positioned at the descending end position P1 as shown in FIG. The screw can be released by moving. Note that the stem 6 also rotates together with the rotation of the pressing head 5.

  When the screwing is released, the pressing head 5 is detached from the restricting cylinder 12, so that the piston guide 13, the stem 6 and the pressing head 5 are integrally moved upward using the upward biasing force of the coil spring 15 against the stem 6. be able to. Thereby, as shown in FIG. 2, the stem 6 and the pressing head 5 can be moved to the rising end position P2, and the pressing head 5 can be shifted to a pressable state.

  In the above process, since the top wall portion of the guide tube 13B in the piston guide 13 engages with the lower end of the inner tube 41 in the piston 11, the piston 11 is also moved upward. As a result, the pressure in the cylinder 10 is reduced, so that the valve member 14 opens the lower end opening of the cylinder 10, and the contents in the container body 2 flow into the cylinder 10 through the suction pipe 22. In addition, since the upper end edge of the outer cylinder 40 of the piston 11 engages with the lower end edge of the closed cylinder portion 31 of the seal cylinder 10b, the seal cylinder 10b is moved further away from the air introduction hole 20 and moved. The outer cylinder 40 covers the air introduction hole 20 of the cylinder 10.

As described above, when the contents are to be discharged after the pressing head 5 is shifted to a state where the pressing head 5 can be pressed, the pressing head 5 is pressed and moved downward together with the stem 6 and the piston guide 13. Then, first, the top wall portion of the guide cylinder 13B in the piston guide 13 is separated downward from the lower end of the inner cylinder 41 of the piston 11, so that the cylinder 10 and the stem 6 communicate with each other. Then, the lower end portion of the outer cylindrical portion 6 </ b> A in the stem 6 comes into contact with the connecting portion 42 of the piston 11 by further downward movement. Therefore, if the downward movement is further continued, the piston 11 also moves downward, so that the contents in the cylinder 10 are adjacent to each other in the circumferential direction of the piston guide 13 while the piston 11 is spaced downward from the air introduction hole 20. It flows into the stem 6 between the protrusions 45 and through the introduction groove 35 of the stem 6.
As a result, the contents flowing into the stem 6 can be discharged to the outside through the discharge holes 5a.

  Next, when the pressing of the pressing head 5 is released, the piston guide 13, the piston 11, the stem 6 and the pressing head 5 are moved upward by the upward biasing force (elastic restoring force) of the coil spring 15 in the same manner as described above. The contents move in the container body 2 and flow into the cylinder 10. Thereby, it is possible to prepare for the discharge operation by the next pressing of the pressing head 5.

In particular, according to the discharge container 1 of the present embodiment, the engagement convex portion 61 on the cylinder 10 side engages in the vertical groove portion 60a of the engagement concave portion 60 on the mouth portion 2a side of the container main body 2 and The movement of the cylinder 10 in the circumferential direction is restricted, and the cylinder 10 and the mouth portion 2a are combined so as not to rotate. Therefore, even if the pressing cylinder 5 and the cylinder 10 try to rotate together with the pressing head 5 when the pressing head 5 positioned at the descending end position P1 is rotated around the container axis O, this rotation is effective. Can be prevented.
Therefore, even if the rotational torque of the pressing head 5 and the stem 6 is equal to or higher than the tightening torque of the mounting cap 3 with respect to the mouth 2b of the container body 2, the mounting cap 3 itself does not rotate together. It is possible to prevent the mounting cap 3 from being detached from the mouth portion 2a. Furthermore, since the pressing head 5 and the stem 6 can be appropriately rotated with respect to the restriction cylinder 12, the pressing head 5 and the stem 6 can be quickly moved upward, improving the operability at the start of use. The contents can be quickly discharged.

Moreover, since the engagement convex part 61 is formed in the seal | sticker cylinder 10b, it is not necessary to provide separately sealing members, such as packing, which seals between the cylinder 10 and the opening part 2a of the container main body 2. FIG. Therefore, the cost can be reduced and the configuration can be simplified.
Furthermore, the bending rigidity of the engaging convex part 61 can also be ensured easily.

  The technical scope of the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.

For example, the configuration of the mounting cap 3, the piston guide 13, the stem 6, the valve member 14, and the like is not limited to the above embodiment, and may be changed as appropriate.
Moreover, although the engagement recessed part 60 was formed in the mouth part 2a side of the container main body 2, and the engagement convex part 61 was formed in the cylinder 10 side, on the contrary, the engagement convex part 61 was formed in the mouth part 2a side. The engaging recess 60 may be formed on the cylinder 10 side.

  Furthermore, although the engagement recessed part 60 formed in the mouth part 2a side of the container main body 2 was formed with the vertical groove part 60a and the guide groove part 60b, it is not limited to this case, and is formed only with the vertical groove part 60a. It doesn't matter. Even in this case, the engagement between the engagement recess 60 and the engagement protrusion 61 allows the mouth portion 2a and the cylinder 10 to be combined in a non-rotatable manner, so that the same effect can be achieved. .

However, when configured as in the above embodiment, when the cylinder 10 is combined with the mouth portion 2a of the container body 2, for example, the engaging convex portion 61 formed on the cylinder 10 side is placed on the mouth portion 2a side. After alignment with the guide groove portion 60b of the formed engagement recess 60, the mounting cap 3 is screwed into the mouth portion 2a together with the cylinder 10 along the rotation direction T, so that the engagement protrusion 61 is guided to the guide groove portion. While moving in the circumferential direction along 60b, it can finally be guided into the vertical groove 60a and easily and reliably engaged with the vertical groove 60a.
Thus, since the screwing is used, the mounting operation of the pump 4 to the mouth portion 2a and the engaging operation of the engaging concave portion 60 and the engaging convex portion 61 can be smoothly performed without using excessive force. It is easy to perform both operations more reliably.
In addition, since the engaging convex portion 61 is formed so that the protruding amount toward the outside in the radial direction gradually decreases along the rotation direction T, it is easy to perform the screwing operation with less resistance, and the above-described operational effects are more effective. Can be successful.

Furthermore, in the said embodiment, although the engagement convex part 61 was formed in the outer peripheral surface of the seal cylinder 10b, it is not limited to this case.
For example, a plurality of vertical rib-shaped connecting projections extending radially outward from the cylinder 10 are formed in a portion positioned below the flange portion 10a at intervals in the circumferential direction, and the radial outer ends of these connecting projections The parts may be engaged with the engaging recess 60, respectively. In this case, each connection protrusion can function as the second engaging portion. Even in this case, since the cylinder 10 and the mouth portion 2a can be combined so as not to rotate, the same effect can be achieved.
In this case, since the seal cylinder 10b is not provided, for example, an annular packing or the like is interposed between the opening edge of the mouth portion 2a of the container body 2 and the flange portion 10a, thereby sealing the container body 2. Is preferably increased.
