Description

  The present invention relates to a discharge container.

As a discharge container of this type, it has a container main body in which contents are stored, a mounting cap mounted on the mouth of the container main body, and a stem that is supported on the inner side of the mounting cap so as to be movable downward in an upwardly biased state. A pump and a headed cylindrical presser head that is attached to the upper end of the stem and has a discharge hole for the contents, and a presser head located at the lower end position are screwed together to restrict the upward movement of the presser head and stem. It is known that includes a regulating cylinder that performs the above operation and a cover cylinder that covers the pressing head from the outside in the radial direction (see, for example, Patent Document 1).
In such a discharge container, the pressing head is exposed by breaking and removing the weakened portion formed in the cover cylinder. Then, the pressing head and the stem are moved up by releasing the screwing between the pressing head and the regulating cylinder. Here, it is possible to determine whether or not the discharge container has been opened based on the presence or absence of the cover cylinder.

However, in the above conventional discharge container, when releasing the screwing between the pressing head and the regulating cylinder, it is necessary to break the weakened portion in advance and remove the cover body, and there is room for improvement in operability at the time of opening. .
Accordingly, an object of the present invention is to provide a discharge container that can be easily broken whether or not the discharge container has been opened, and has improved operability at the time of opening.

  The present invention employs the following means in order to solve the above problems. That is, the discharge container of the present invention is supported in a downwardly movable state in an upwardly biased state inside a container main body in which contents are stored, a mounting cap mounted on the mouth of the container main body, and the mounting cap. A pump having a stem and a top-side cylindrical pressing head mounted on the upper end of the stem and having a discharge hole for contents, and the pressing head positioned at the lower end position is screwed to the pump. A restricting cylinder for restricting the upward movement of the pressing head and the stem, and a pilfer proof portion protruding downward is connected to a peripheral wall portion of the pressing head via a weakening portion that can be broken. The pilfer proof portion is formed with a rising restriction locking portion that locks the rising movement by being locked to any one of the mounting cap, the restriction cylinder, and the container body. To

In this invention, when the pressing head at the lower end position is rotated in the screw release direction with respect to the regulating cylinder, and the pushing head is moved upward with respect to the mounting cap and the regulating cylinder, the rising regulation locking portion is Since it is locked to any one of the mounting cap, the regulating cylinder, and the container main body, a vertical pulling force acts on the weakened portion. As a result, the weakened portion is broken and the pilfer proof portion falls from the pressing head. Therefore, it can be easily determined by visual recognition whether or not the screwing of the pressing head and the regulating cylinder has been released.
Further, it is not necessary to remove the cover body as in the prior art in order to release the screwing between the pressing head and the regulating cylinder, and the pressing head and the regulating cylinder can be obtained only by the relative rotation operation between the pressing head and the regulating cylinder. Therefore, it is possible to provide excellent operability.

In the discharge container of the present invention, any one of the mounting cap, the restriction cylinder, and the container body has the rising restriction locking portion locked in a circumferential direction around the central axis of the stem. A circumferential locking portion may be formed.
In this invention, when releasing the screwing between the pressing head and the regulating cylinder, the upward regulating locking portion and the circumferential locking portion are locked together in the circumferential direction, thereby pulling the weakened portion in the vertical direction. Not only the force but also the torsional force in the circumferential direction can be applied. Thereby, a weakened part can be fractured reliably.

In the discharge container of the present invention, the pilfer proof portion may be formed with a breakable portion that can be divided in the circumferential direction.
In this invention, when releasing the screwing between the pressing head and the restriction cylinder, it is possible to reduce the force required to expand the diameter of the pilfer proof part, and the rising restriction locking part is the circumferential locking part. It is easy to get on and the pilfer proof part can be applied with a large circumferential tensile force. Thereby, a fracture | rupture part can be made to fracture | rupture reliably.

  According to the discharge container of the present invention, the weakening portion is broken by applying a tensile force in the vertical direction to the weakening portion by the relative rotation operation of the pushdown head and the regulating cylinder, and the pilfer proof portion is pushed down by the pressing head. Therefore, it is possible to easily determine whether or not the screwing between the pressing head and the regulating cylinder has been released, and to provide excellent operability.

The cylinder 32 is formed in a multistage cylindrical shape whose diameter is reduced stepwise from the upper side toward the lower side.
At the upper end of the cylinder 32, a flange portion 34 that protrudes radially outward is formed in an annular shape over the entire circumference. The flange portion 34 is disposed on the upper opening opening edge of the mouth portion 3 of the container body 2 via the packing 35, and is sandwiched between the top wall portion 21 of the mounting cap 11 and the mouth portion 3 in the vertical direction. Thereby, the cylinder 32 is supported in the state inserted in the opening | mouth part 3 of the container main body 2. FIG.

  The cylinder 32 is formed with a cylindrical protruding cylindrical portion 36 extending upward from the inner peripheral edge of the flange portion 34. An air hole 32 </ b> A that connects the inside of the container body 2 and the inside of the cylinder 32 is formed in a portion of the cylinder 32 that is positioned below the flange portion 34. Further, in the cylinder 32, a valve member (not shown) for opening and closing the lower end opening of the cylinder 32 and a biasing means (not shown) such as a coil spring for biasing the stem 31 upward are disposed.

  The valve member is disposed so as to be located in the lower end portion of the cylinder 32. This valve member is a check valve, and maintains a state where the lower end opening of the cylinder 32 is closed when the pressure in the cylinder 32 is pressurized, and opens the lower end opening of the cylinder 32 when the pressure in the cylinder 32 is reduced. This restricts the contents in the cylinder 32 from returning to the container main body 2 through the lower end opening of the cylinder 32 when the pressure in the cylinder 32 is pressurized, and the contents in the container main body 2 are reduced when the pressure in the cylinder 32 is reduced. It is allowed to flow into the cylinder 32 through the lower end opening of the cylinder 32.

  The piston is in close sliding contact with the inner peripheral surface of the cylinder 32, and moves up and down in the cylinder 32 along with the stem 31. The biasing means is disposed, for example, between the piston and the valve member, and biases the stem 31 upward via the piston. An annular space defined between the stem 31 and the cylinder 32 and communicating with the air hole 32A is formed on the stem 31 in the cylinder 32.

  The pressing head 13 includes a cylindrical main body cylinder portion 41, a cylindrical attachment cylinder portion 43 that extends downward from the top plate portion 42 of the main body cylinder portion 41, and is attached to the upper end of the stem 31. The nozzle tube portion 44 protrudes forward from the main body tube portion 41 and communicates with the inside of the mounting tube portion 43, and the discharge hole 13A is formed at the tip thereof. And a cylindrical screw tube portion 45 extending downward from the top plate portion 42 of 41. The main body cylinder part 41, the mounting cylinder part 43, and the screw cylinder part 45 are arranged coaxially with the container axis O.

  As shown in FIGS. 1 to 3, an annular upper pill fur proof portion (pill fur proof portion) 47 is connected to a lower end edge of the peripheral wall portion 46 of the main body cylinder portion 41 via a weakening portion 48 that can be broken. Has been. A plurality of weakening portions 48 are arranged at intervals in the circumferential direction. Note that the structure of the weakened portion 48 may be a thin portion that continuously extends over the entire circumference in the circumferential direction.

The lower end edge of the upper pilfer proof portion 47 faces the upper surface of the top wall portion 21 in the vertical direction, and is spaced upward from the upper surface of the top wall portion 21.
On the inner peripheral surface of the upper pill fur proof portion 47, a plurality (four in the present embodiment) of rising restricting locking portions 49 extending gradually upward in the radial direction are formed at equal intervals in the circumferential direction. ing. In addition, the number of the raising restriction | limiting latching parts 49 is not limited to four.
The upper pilfer proof portion 47 is formed with a plurality (two in this embodiment) of rupture portions 47A that can be divided in the circumferential direction at equal intervals in the circumferential direction. Note that the number of the rupture portions 47A is not limited to one.
As shown in FIGS. 1 and 3, a female screw portion is formed on the inner peripheral surface of the screw cylinder portion 45.

  As shown in FIGS. 1 to 3, the restriction cylinder 14 includes an annular ceiling wall 51 in a top view and a cylindrical mounting cylinder 52 that protrudes in the vertical direction from the inner peripheral edge of the ceiling wall 51. A cylindrical outer wall portion 53 that extends slightly downward from the radially inner side of the outer peripheral edge portion of the top wall portion 51, and a screw cylinder of the pressing head 13 that is disposed between the mounting tube portion 52 and the outer wall portion 53. And a cylindrical inner wall portion 54 to which the portion 45 is screwed. The top wall 51, the mounting cylinder 52, the outer wall 53, and the inner wall 54 are arranged coaxially with the container axis O.

  The outer peripheral edge portion of the top wall portion 51 protrudes radially outward from the outer wall portion 53, and as shown in FIG. 1 and FIG. It is locked from. The top wall portion 51 is formed with a smaller diameter than the top plate portion 42 of the main body cylinder portion 41, and is located below the weakening portion 48. Furthermore, the lower end of the screw cylinder portion 45 is in proximity to or in contact with the upper surface of the top wall portion 51.

A male screw portion to which a female screw portion formed on the screw tube portion 45 is screwed is formed on an outer peripheral surface of a portion of the attachment tube portion 52 located above the top wall portion 51.
On the outer wall portion 53, a ratchet portion (circumferential locking portion) 55 that the ascent restriction locking portion 49 locks in the circumferential direction is provided protruding outward in the radial direction. As shown in FIG. 2, a plurality of ratchet portions 55 (four in this embodiment) are formed at equal intervals in the circumferential direction. Note that the number of ratchet portions 55 is not limited to four, but is preferably a number corresponding to the rising restriction locking portions 49.

The side surface 55A on the loosening direction R1 side of the ratchet portion 55 is inclined so as to be directed in the tightening direction R2 toward the radially outer side. On the other hand, the side surface 55B of the ratchet portion 55 on the tightening direction R2 side extends substantially in the radial direction. That is, the inclination angle of the side surface 55A on the loosening direction R1 side in the ratchet portion 55 with respect to the circumferential direction is smaller than the side surface 55B on the tightening direction R2 side.
In addition, the radial direction outer end of the ratchet part 55 is located on the same plane as the outer peripheral edge of the top wall part 51 as shown in FIGS. The protruding amount of the ratchet portion 55 outward in the radial direction may be appropriately changed.

Further, as shown in FIG. 1, the lower edge of the outer wall portion 53 is spaced apart from the top wall portion 21 of the mounting cap 11 with a slight gap therebetween, but from the lower edge of the upper pill fur proof portion 47. Is also located below.
The inner wall portion 54 is disposed radially inward from the inner peripheral edge portion of the top wall portion 21 of the mounting cap 11. A projecting cylinder portion 36 disposed between the inner wall portion 54 and the mounting cylinder portion 52 is fitted into the inner wall portion 54 by undercut fitting.

Next, a method for assembling the discharge container 1 having the above configuration will be described.
First, a method for assembling the discharge container 1 will be described. First, the mounting cylinder portion 43 of the pressing head 13 is fitted to the upper end portion of the stem 31 of the pump 12, and the pressing head 13 is mounted on the stem 31. Next, while the pressing head 13 is moved downward so as to push down the stem 31 against the biasing force of the biasing means, the mounting cylinder portion 52 of the regulating cylinder 14 is fixed to the pressing head 13 while the pressing head 13 is fixed. On the other hand, by rotating around the container axis O, the screw cylinder part 45 of the pressing head 13 and the attachment cylinder part 52 of the restriction cylinder 14 are screwed together. The pressing head 13 and the mounting cylinder portion 52 may be relatively rotated around the container axis O, and the pressing head 13 is rotated around the container axis O with respect to the mounting cylinder portion 52. The screw tube portion 45 and the mounting tube portion 52 of the restriction tube 14 may be screwed together.

Here, since the side surface 55A on the loosening direction R1 side of the ratchet portion 55 is inclined so as to go radially outward as it goes to the tightening direction R2, the rise restricting locking portion 49 causes the ratchet portion 55 to move in the loosening direction. Ride smoothly along the side surface 55A on the R1 side. Therefore, an excessive circumferential tensile force does not act on the break portion 47A, and the break portion 47A is not broken.
Thereby, the pressing head 13 is screwed to the restriction cylinder 14 at the lowered end position, and the upward movement of the pressing head 13 and the stem 31 is restricted.

Thereafter, after the container body 2 is filled with the contents, the mounting cap 11 is mounted on the mouth 3 of the container body 2 by, for example, plugging, so that the discharge pump 4 is combined with the container body 2 integrally.
The discharge container 1 is assembled as described above.

Then, the usage method of the discharge container 1 is demonstrated.
In the unused state, as shown in FIG. 1, the pressing head 13 is at the lower end position, and the ascending restriction locking portion 49 is locked from below with respect to the outer peripheral edge portion of the top wall portion 51 of the restriction cylinder 14. doing. Further, the upper pilfer proof portion 47 is spaced upward from the lower end edge of the upper cap portion 47 and the top wall portion 21 of the mounting cap 11.
Then, when the pressing head 13 is rotated about the container axis O with respect to the mounting cap 11 and the screwing of the screw cylinder portion 45 and the mounting cylinder portion 52 is released, the pressing head 13 moves relative to the regulation cylinder 14. Try to move upward.

  However, since the rising restriction locking portion 49 is locked from below with respect to the outer peripheral edge portion of the top wall portion 51, a vertical tensile force acts on the weakening portion 48. In addition, since the ascending restriction locking portion 49 is locked in the circumferential direction with the side surface 55 </ b> B of the ratchet portion 55, a circumferential twisting force also acts on the weakening portion 48. As a result, the weakened portion 48 is broken, and the upper pill fur proof portion 47 falls from the peripheral wall portion 46 onto the top wall portion 21 as shown in FIG. Here, since the ascending restriction locking portions 49 are arranged at equal intervals in the circumferential direction, an upward and downward tensile force is applied evenly in the circumferential direction to the upper pill fur proof portion 47, and the weakening portion 48 is more Breaks reliably.

  At this time, since the rupture portion 47A is formed in the upper pill fur proof portion 47, the force required to expand the diameter of the upper pill fur proof portion 47 is larger than in the case where the rupture portion 47A is not formed. Has been reduced. Therefore, the ascending restriction locking portion 49 rides on the side surface 55B of the ratchet portion 55. At that time, a large circumferential tensile force is applied to the upper pill fur proof portion 47, and the breaking portion 47A is broken. Here, since the breaking portions 47A are arranged at equal intervals in the circumferential direction, a tensile force in the circumferential direction is applied equally to the breaking portion 47A in the circumferential direction, and the breaking portion 47A is more reliably broken.

In addition, since the rising restriction locking portion 49 can easily ride on the ratchet portion 55 by forming the breaking portion 47A in the upper pilfer proof portion 47, the circumferential twisting force acting on the weakening portion 48 is reduced. It is sufficient to break the weakened portion 48. The break portion 47A may be broken at the same time when the upper pill fur proof portion 47 falls from the peripheral wall portion 46, or may be broken before the upper pill fur proof portion 47 falls.
In this way, it is visually recognized that the upper pill fur proof portion 47 is detached from the peripheral wall portion 46 and dropped onto the top wall portion 21 and that the upper pill fur proof portion 47 is broken at the break portion 47A. Thus, it is determined whether or not the lock between the pressing head 13 at the lower end position and the restriction cylinder 14 has been released.

  When the screwing of the pressing head 13 is released, the stem 31 and the pressing head 13 are integrally moved upward and moved to the standby position by the biasing force of the biasing means. Thereby, the pressing head 13 can be shifted to a state where it can be pressed down. In this state, when the pressing head 13 is pushed down and moved downward together with the stem 31, the piston moves downward in the cylinder 32, so that the pressure in the cylinder 32 increases. Thereby, the contents in the cylinder 32 are supplied into the nozzle cylinder portion 44 and discharged to the outside through the discharge holes 13A. In addition, when the pressing head 13 is pressed, the female screw portion of the screw tube portion 45 abuts on the male screw portion of the mounting tube portion 52, thereby restricting further pressing of the pressing head 13.

When the pressing of the pressing head 13 is released, the stem 31 and the pressing head 13 are restored to the standby position by the biasing force of the biasing means. By this restoring movement, the inside of the cylinder 32 becomes a negative pressure, so that the contents in the container body 2 are sucked into the cylinder 32. This prepares for the next discharge operation by the pressing head 13.
In addition, the pressing head 13 can be screwed to the regulation cylinder 14 by rotating the pressing head 13 with respect to the regulation cylinder 14 in a pressed state.

As described above, according to the discharge container 1 according to the present embodiment, the weakening portion 48 is broken by causing the tensile force in the vertical direction to act on the weakening portion 48 by the relative rotation operation of the pressing head 13 and the regulating cylinder 14. Since the upper pilfer proof portion 47 is dropped from the pressing head 13, it can be easily determined by visual confirmation whether the pressing head 13 and the regulating cylinder 14 have been unscrewed or not. Can be provided.
Here, when releasing the screwing between the pressing head 13 and the restriction cylinder 14, not only the vertical tensile force but also the circumferential twisting force is applied to the weakened portion 48, so that the weakened portion 48 is reliably broken. it can. Further, since the breaking portion 47A is formed in the upper pill fur proof portion 47, a large tensile force in the circumferential direction can be applied to the upper pill fur proof portion 47, and the breaking portion 47A can be reliably broken.

2nd Embodiment of the discharge container by this invention is described based on drawing. The embodiment described here has the same basic configuration as the above-described embodiment. Therefore, in the following drawings, the same components as those in the above drawings are denoted by the same reference numerals, and the description thereof is omitted.
In the discharge container 100 according to this embodiment, as shown in FIGS. 5 and 6, the upper pill fur proof portion 101 is not formed with a fracture portion, and the regulation cylinder 102 is not formed with an outer wall portion and a ratchet portion. .
In such a discharge container 100 as well, as with the discharge container 1 according to the first embodiment described above, the pressing head 13 is rotated around the container axis O with respect to the mounting cap 11 to thereby form the screw cylinder portion 45 and the attachment cylinder portion 52. When the screwing is released, the rise restricting locking portion 49 is locked to the outer peripheral edge portion of the top wall portion 51 from below, so that the weakening portion 48 has a vertical tensile force. As a result, the weakened portion 48 is broken, and the upper pill fur proof portion 101 falls from the pressing head 13 as shown in FIG.
However, in the discharge container 100 according to the present embodiment, unlike the discharge container 1 according to the first embodiment, the upper pill fur proof portion 101 is not formed with a fracture portion, and the ratchet portion is formed in the regulation cylinder 102. Therefore, a circumferential twisting force does not act on the weakened portion 48, and a large circumferential tensile force does not act on the upper pill fur proof portion 101.

In addition, this invention is not limited to the said embodiment, A various change can be added in the range which does not deviate from the meaning of this invention.
For example, the lower end edge of the upper pilfer proof portion is separated from the upper surface of the top wall portion of the mounting cap, but may be close to or in contact with the upper surface of the top wall portion. Even if it is separated from the upper surface of the top wall portion of the mounting cap, it can be visually recognized that the upper pilfer proof portion is detached from the pressing head.
The upper pilfer proof portion extends downward from the lower end edge of the peripheral wall portion, but may extend downward from other portions of the peripheral wall portion.
Although the ratchet part is formed in the regulation cylinder, the circumferential direction latching part of other structures may be formed as long as it can be latched with the rising regulation latching part in the circumferential direction. The part may not be formed. Here, the circumferential locking portion may be formed on the container body or the mounting cap instead of the regulation cylinder. Moreover, the circumferential direction latching | locking part may be formed in the member different from the member which a raise control latching part latches. For example, the circumferential locking portion may be formed on the mounting cap or the container body when the ascent restriction locking portion is locked to the restriction cylinder.
The rising restriction locking portion is locked to the restriction cylinder, but may be locked to the container body or the mounting cap.

  According to the present invention, industrial applicability is recognized for a discharge container that can be easily broken whether or not the discharge container has been opened, and has improved operability at the time of opening.
