JP 2006-327612 A

  However, in the conventional discharger, it is difficult to determine whether or not the cover body has been removed when the cover body is easily detached from the main body of the discharger and is attached again after being removed. There was a problem that it was difficult to respond to the request.

  The present invention has been made in consideration of such circumstances, and the cover body is a discharge device even if an external force is intentionally or unexpectedly applied by another person during distribution, storage or sales display before sales. It is possible to prevent the cover body from being detached from the main body and to easily determine whether or not the cover body has been removed from the main body of the discharger. Another object of the present invention is to provide a discharger that can prevent the contents from being discharged due to an external force applied unexpectedly.

  In order to solve the above-mentioned problems and achieve such an object, a discharger according to the present invention includes a top cylindrical mounting cap mounted on the mouth of a container body containing the contents, and this mounting A pump having a stem penetrating the cap so as to be movable downward in an upwardly biased state, and a pressing head mounted on the upper end of the stem and having a discharge hole formed therein, and pressing the pressing head A discharger having a discharger main body in which the contents in the container are transferred and discharged from the discharge hole by moving the stem downward and operating the pump, wherein the mounting is included in the discharger main body. A cover body covering a portion located above the top wall portion of the cap; the cover body is located between the top wall portion of the mounting cap and the pressing head in the main body of the discharger; head The outer cylinder is detachably fitted to an intermediate part having a smaller diameter than the outer diameter, and the lower cylinder part is disposed on the top wall part of the mounting cap, and the lower cylinder part is formed integrally with the lower cylinder part and the press An upper cylindrical portion covering the head, and the lower cylindrical portion has an opening extending over the entire length in the vertical direction and is formed in a C-shape when viewed from above, along the radial direction of the cover body and the discharger body Along with the relative advance and retreat movement, the intermediate portion is fitted and detached from the inside of the lower cylinder portion by passing through the opening portion in the radial direction, and the upper cylinder portion moves the pressing head outward in the radial direction. The peripheral wall portion includes a first peripheral wall body and a second peripheral wall body, each of which is formed in a C shape in a top view, and both the circumferences of the first peripheral wall body and the second peripheral wall body, respectively. One of the end parts is the hinge part The other peripheral end portions are connected by a breakable connecting member, and the lower end portion of the first peripheral wall body is connected to the upper end portion of the lower cylinder portion. It is connected.

  According to this invention, before the connecting member of the upper cylinder part is broken, the peripheral wall part of the upper cylinder part covers the pressing head from the outside in the radial direction. Since the movement is restricted and the intermediate portion having a diameter smaller than the outer diameter of the pressing head is fitted in the lower cylinder portion, the upper end of the lower cylinder portion comes into contact with the lower end of the pressing head, thereby discharging the cover body. The upward movement with respect to the main body is also restricted. Therefore, it is possible to prevent the cover body from being detached from the main body of the dispenser even if an external force is intentionally or unexpectedly applied by another person during distribution, storage or sales display before sales.

Further, in order to remove the cover body from the discharger main body, the first peripheral wall body and the second peripheral wall body are rotated around the hinge portion in a direction in which the other peripheral end portions are separated from each other. Then, the cover body and the discharger body are moved relatively apart from each other in the radial direction so that the intermediate part of the discharger body passes through the opening of the lower cylinder part in the radial direction, and the inside of the lower cylinder part To leave.
Thus, in order to remove the cover body from the main body of the discharger, the connecting member of the upper tube portion must be broken, and after the breaking of the connecting member, the second peripheral wall body is against the first peripheral wall body. It is unstable and cannot be restored to the initial posture, and the purchaser can easily determine whether or not the cover body has been removed from the dispenser body.

  When the purchaser stores the contents after use, the cover body and the discharger main body with the opening of the lower cylinder part and the intermediate part of the discharger main body facing each other in the radial direction. Is moved relatively close in the radial direction, the intermediate portion of the discharger body is passed through the opening of the lower cylinder part in the radial direction and fitted into the lower cylinder part, and the cover body is attached to the discharger body. Installing. Thereby, the pressing head is covered with the first peripheral wall body of the upper cylindrical portion from the outside in the radial direction, and the lower end of the lower cylindrical portion is disposed on the top wall portion of the mounting cap, and further, the upper end of the lower cylindrical portion is The lower end of the pressing head faces or abuts in the vertical direction.

As described above, when the cover body is attached to the main body of the dispenser, regardless of whether it is in distribution before storage, storage or sales display, or storage after the purchaser uses the contents, the lower cylinder The lower end of the part is disposed on the top wall of the mounting cap, and the upper end of the lower cylinder part and the lower end of the pressing head are opposed to or in contact with each other in the vertical direction. Even when an external force to be moved is applied, the force is transmitted to the mounting cap via the lower cylinder portion and is received by the container body, and the downward movement of the pressing head and the stem can be prevented.
Therefore, when the cover body is attached to the main body of the dispenser, whether it is distributed before storage, at the time of storage or at the time of display, or at the time of storage after use of the contents by the purchaser, it is intentional by others. It is possible to prevent the contents from being discharged due to an external force applied to the user.

  Here, on the outer peripheral surface of the pressing head, a discharge cylinder having the discharge hole formed at the tip thereof protrudes outward in the radial direction, and a central portion in the circumferential direction of the first peripheral wall body of the upper cylinder portion Alternatively, a container with a closed end, in which the discharge cylinder is accommodated, may be provided so as to protrude outward in the radial direction.

  In this case, since the storage body protrudes radially outward at the central portion in the circumferential direction of the first peripheral wall body of the upper cylindrical portion, the cover body is again attached to the discharger body after use of the contents. For mounting, when the opening of the lower cylinder and the intermediate portion of the discharger body are opposed to each other in the radial direction, the tip of the discharge cylinder and the inside of the storage body are opposed to each other in the radial direction. It becomes possible. As a result, when the cover body and the discharger body are moved relatively close to each other in the radial direction, the intermediate part of the discharger body is fitted into the lower tube part while the discharge tube is inserted into the housing body. The cover body can be easily attached to the discharger body.

  The radius of curvature of the inner peripheral surface of the second peripheral wall body may be larger than the radius of curvature of the outer peripheral surface of the pressing head.

  In this case, since the curvature radius on the inner peripheral surface of the second peripheral wall body is larger than the curvature radius on the outer peripheral surface of the pressing head, the second peripheral wall body is externally fitted to the pressing head after the connecting member is broken. Can not be fixed. Therefore, the second peripheral wall body becomes unstable not only with respect to the first peripheral wall body but also with respect to the pressing head, and the initial posture of the second peripheral wall body can be surely made unrecoverable. It can be determined even more easily whether or not it has been removed from the discharger body.

  Further, the pressing head includes a top wall portion and a cylindrical body extending downward from the top wall portion, and an upper end of the lower cylindrical portion is adjacent to or contacted with a lower end of the cylindrical body from the lower side. You may touch.

  In this case, since the upper end of the lower cylinder part is close to or abuts the lower end of the cylinder of the pressing head from the lower side, it is necessary to use the contents by the purchaser at the time of distribution, storage or sales display before the sale. Regardless of whether it is stored at a later time, when the cover body is attached to the main body of the dispenser, the pressing head is more reliably prevented from being pushed down by an external force applied intentionally or unexpectedly by another person. Can do.

  According to the present invention, it is possible to prevent the cover body from being detached from the main body of the dispenser even when external force is intentionally or unexpectedly applied by another person during distribution, storage or sales display before sales, etc. It is possible to easily determine whether or not the cover body has been removed from the main body of the dispenser, and even after the purchaser has started using the contents, the contents are unexpectedly applied by the external force. Can be prevented from being discharged.

A female thread portion is formed on the inner peripheral surface of the peripheral wall portion 21, and the female cap portion is screwed into a male thread portion formed in the mouth portion 2 a of the container body 2, whereby the mounting cap 11 is attached to the container body 2. It is installed.

The pump 13 includes the stem 12, a cylinder 23 in which a lower portion of the stem 12 is disposed so as to be movable up and down, a piston member (not shown) disposed in the cylinder 23 so as to be vertically slidable, and the stem 12. And a biasing member (not shown) that biases the head upward.
The upper portion of the stem 12 protrudes upward from the upper end of the cylinder 23 and is disposed in the guide tube portion 22 of the mounting cap 11, and the upper end portion protrudes upward from the upper end of the guide tube portion 22.
The cylinder 23 is formed in a cylindrical shape and is disposed coaxially with the central axis O. At the upper end of the cylinder 23, a flange portion 23 a is provided so as to protrude outward in the radial direction over the entire circumference, and this flange portion 23 a is provided on the lower surface of the top wall portion 17 of the mounting cap 11 and the mouth of the container body 2. It is sandwiched in the vertical direction by the packing 24 on the opening edge of the portion 2a. The upper end of the pipe 25 is fitted into the lower end of the cylinder 23, and the lower end opening of the pipe 25 is located at the bottom of the container body 2.

The pressing head 14 includes a top wall portion 26, a mounting cylinder portion (cylinder body) 27 extending downward from the center portion on the lower surface of the top wall portion 26, and a downward direction from the outer peripheral edge of the top wall portion 26. A surrounding cylinder portion (cylinder body) 28 that extends and surrounds the mounting cylinder portion 27 from the outside in the radial direction, and a discharge cylinder 29 that protrudes radially outward from the outer peripheral surface of the surrounding cylinder portion 28; It has.
The upper end portion of the stem 12 is fitted in the mounting cylinder portion 27, and the inside of the mounting cylinder portion 27 and the inside of the stem 12 communicate with each other. The discharge hole is formed at the tip of the discharge cylinder 29, and the inside of the discharge cylinder 29 communicates with the inside of the mounting cylinder portion 27.

  In the surrounding cylinder portion 28, the outer peripheral surface of the upper portion 28a is gradually reduced in diameter from the upper side toward the lower side, and the outer peripheral surface of the lower portion 28b has the same outer diameter over the entire length in the vertical direction. The outer diameter of the lower part 28b of the surrounding cylinder part 28 is equivalent to the outer diameter at the lower end of the upper part 28a. The inner diameter of the lower portion 28 b of the surrounding tube portion 28 is larger than the outer diameter of the guide tube portion 22 of the mounting cap 11, and the guide tube portion 22 is lowered into the surrounding tube portion 28 as the pressing head 14 moves up and down. It is designed to move forward and backward from the side. Further, when the cover body 18 is removed from the discharger body 16 as described later, the lower end opening edge of the surrounding tube portion 28 is opposed to the upper surface of the top wall portion 17 of the mounting cap 11 from above over the entire circumference. It has become. In the illustrated example, the upper end portion of the guide tube portion 22 is always located in the surrounding tube portion 28 regardless of whether the press head 14 is pressed or not pressed.

In the above configuration, when the pressing head 14 is pressed, the stem 12 is first moved downward. Following the movement of the stem 12, the piston member moves downward while being in sliding contact with the inner peripheral surface of the cylinder 23. As a result, the contents in the cylinder 23 are compressed, and the compressed contents in the cylinder 23 enter the stem 12 and move upward in the stem 12.
Thereafter, when the pressing of the pressing head 14 is released, the piston member is restored and moved upward while being in sliding contact with the inner peripheral surface of the cylinder 23 by the upward biasing force of the biasing member. As a result, the inside of the cylinder 23 is depressurized, and the contents stored in the container body 2 are sucked into the cylinder 23 through the pipe 25.

  In the present embodiment, as shown in FIGS. 1 to 6, the cover body 18 guides the mounting cap 11 located between the top wall portion 17 of the mounting cap 11 and the pressing head 14 in the discharger body 16. A lower cylinder part 30 is detachably fitted to the cylinder part 22, and an upper cylinder part 31 is formed integrally with the lower cylinder part 30 and covers the pressing head 14.

The lower cylinder portion 30 has a lower end disposed on the top wall portion 17 of the mounting cap 11 and an upper end abutted or brought close to the lower end opening edge of the surrounding cylinder portion 28 of the pressing head 14 to guide the lower cylinder portion 30. The tube portion 22 is externally fitted.
As shown in FIGS. 3 to 5, the lower cylinder portion 30 has an opening 30 a that extends over the entire length in the vertical direction, and is formed in a C shape in a top view. As a result, the lower cylinder part is formed so that the guide cylinder part 22 widens the opening 30a of the lower cylinder part 30 in the circumferential direction with the relative advance and retreat movement along the radial direction of the cover body 18 and the discharger body 16. While elastically deforming 30, it passes through the opening 30 a in the radial direction so that it can be fitted into and detached from the inside of the lower cylindrical portion 30.

The upper cylinder portion 31 includes a top portion 32 that covers the pressing head 14 from above, and a peripheral wall portion 33 that covers the pressing head 14 from the outside in the radial direction over the entire circumference.
The top portion 32 is formed in a flat plate shape and covers the top wall portion 26 of the pressing head 14 over almost the entire region from above.

The peripheral wall portion 33 includes a first peripheral wall body 34 and a second peripheral wall body 35 each formed in a C shape in a top view. Then, one of the peripheral end portions of each of the first peripheral wall body 34 and the second peripheral wall body 35 is connected by a hinge portion 36 as shown in FIGS. 3 to 6. While being configured to be rotatable around the hinge portion 36, the other peripheral end portions are connected to each other by a connecting member that can be broken.
On the outer peripheral surface of the other peripheral end of each of the first peripheral wall body 34 and the second peripheral wall body 35, a first plate-like body 34a and a second plate-like body 35a extending in the vertical direction are directed outward in the radial direction. Projecting separately. The first plate-like body 34 a of the first peripheral wall body 34 has a smaller radial size than the second plate-like body 35 a of the second peripheral wall body 35. In addition, the 1st plate-shaped body 34a is protrudingly provided by the outer peripheral surface of the small diameter part 34c mentioned later among the 1st surrounding wall bodies 34. As shown in FIG.

  A through hole 34f is formed in the first plate-like body 34a. As shown in FIG. 5, the through-hole 34 f includes a small-diameter portion 34 d located on the front surface side that contacts the second plate-like body 35 a in the first plate-like body 34 a and a large diameter located on the back surface side opposite to the front surface. And a diameter portion 34e. In the present embodiment, the connecting member is a protrusion 37 projecting from the surface of the second plate 35a that contacts the first plate 34a. The protrusion 37 includes a breakable connecting portion 37a connected to the surface of the second plate-like body 35a, and a locking portion 37b provided at the tip of the connecting portion 37a. The outer diameter of the locking portion 37b is gradually reduced from the proximal end side on the connection portion 37a side toward the distal end side, and the outer diameter at the proximal end portion is larger than the outer diameter of the connection portion 37a. .

  Accordingly, when the first peripheral wall body 34 and the second peripheral wall body 35 are rotated around the hinge portion 36 so as to bring the other peripheral end portions closer to each other from the state shown in FIG. The stop portion 37b passes through the small diameter portion 34d and enters the large diameter portion 34e while being in sliding contact with the inner peripheral surface of the small diameter portion 34d of the through hole 34f. At this time, as shown in FIG. 4, the surfaces of the first plate 34 a and the second plate 35 a are overlapped with each other, and the end surface 37 c on the proximal end side of the locking portion 37 b of the protrusion 37 is It catches on the inner surface of the large diameter portion 34e. The connecting portion 37a of the protrusion 37 is located in the small diameter portion 34d of the through hole 34f.

  And if the 1st surrounding wall body 34 and the 2nd surrounding wall body 35 are rotated around the hinge part 36 so that each other surrounding edge part may space apart, the base end side in the latching | locking part 37b of the protrusion 37 will be demonstrated. When the end surface 37c is hooked on the inner surface of the large diameter portion 34e of the through hole 34f, the connection portion 37a of the protrusion 37 is broken.

Here, the lower end portion of the first peripheral wall body 34 is connected to the upper end portion of the lower cylindrical portion 30 in a state where the central portion in the circumferential direction and the central portion in the circumferential direction of the lower cylindrical portion 30 are aligned with each other. ing. Thereby, the 1st surrounding wall body 34 and the lower cylinder part 30, and the 2nd surrounding wall body 35 are relatively rotatable around the hinge part 36. As shown in FIG.
Further, in the present embodiment, at the center portion in the circumferential direction of the first peripheral wall body 34, a storage body 38 with a closed end, in which the discharge cylinder 29 of the pressing head 14 is stored, protrudes outward in the radial direction. ing. A gap is provided between the inner surface of the storage body 38 and the outer surface of the discharge cylinder 29.

Furthermore, in the present embodiment, the first peripheral wall body 34 includes a large-diameter portion 34b that covers the upper portion 28a of the surrounding tube portion 28 of the pressing head 14 and a small-diameter portion 34c that covers the lower portion 28b of the surrounding tube portion 28. . The upper end edge of the second peripheral wall body 35 is separated below the top portion 32. The second peripheral wall body 35 covers only the lower portion 28b of the surrounding cylinder portion 28 of the pressing head 14, and the upper portion 28a is exposed. Yes. Further, the outer peripheral surface of the upper portion 28a of the surrounding tube portion 28 gradually increases from the lower side to the upper side in the radial direction from the upper end edge of the small diameter portion 34c of the first peripheral wall body 34 and the upper end opening edge of the second peripheral wall body 35. Overhangs. Further, the second peripheral wall 35 is shorter in the vertical direction than the small diameter portion 34 c of the first peripheral wall 34, and the lower end edge of the second peripheral wall 35 is the lower end edge of the first peripheral wall 34. It is located above.
In the present embodiment, the radius of curvature of the inner peripheral surface of the second peripheral wall 35 is larger than the radius of curvature of the outer peripheral surface of the lower portion 28 b of the surrounding cylinder portion 28 of the pressing head 14.

  In the above configuration, in order to remove the cover body 18 from the discharger main body 18, first, the first peripheral wall body 34 and the second peripheral wall body 35 are hinged in the direction in which the other peripheral end portions are separated from each other. The connecting portion 37a of the protrusion 37 is broken by rotating around. Then, by moving the cover body 18 and the discharger main body 16 relatively away from each other along the radial direction, the guide cylinder portion 22 of the mounting cap 11 is passed through the opening 30a of the lower cylinder portion 30 in the radial direction. It is made to detach | leave from the cylinder part 30 inside.

  When the purchaser stores the contents after use, the cover body 18 in a state where the opening 30a of the lower cylinder part 30 and the guide cylinder part 22 of the mounting cap 11 face each other in the radial direction. And the discharger body 16 are moved relatively close to each other in the radial direction so that the guide tube portion 22 is fitted in the lower tube portion 30 by passing through the opening 30a of the lower tube portion 30 in the radial direction. The body 18 is attached to the dispenser body 16. Thereby, the pressing head 14 is covered by the top portion 32 of the upper cylindrical portion 31 from above, and is covered by the first peripheral wall body 34 of the upper cylindrical portion 31 from the outside in the radial direction, and the lower end of the lower cylindrical portion 30 is It is arranged on the top wall portion 17 of the mounting cap 11, and the upper end of the lower cylinder portion 30 and the lower end opening edge of the surrounding cylinder portion 28 of the pressing head 14 are opposed or abutted in the vertical direction.

  As described above, according to the dispenser 1 according to the present embodiment, the peripheral wall portion 33 of the upper cylindrical portion 31 causes the pressing head 14 to move before the projection 37 of the upper cylindrical portion 31 of the cover body 18 is broken. Since the cover body 18 is covered from the outside in the radial direction, the movement of the cover body 18 in the radial direction with respect to the discharger body 16 is restricted, and the guide cylinder portion 22 of the mounting cap 11 is fitted in the lower cylinder portion 30. Since the upper end of the lower cylinder part 30 abuts on the lower end opening edge of the surrounding cylinder part 28 of the pressing head 14, the upward movement of the cover body 18 relative to the discharger body 16 is also restricted.

Therefore, it is possible to prevent the cover body 18 from being detached from the discharger main body 16 even if an external force is intentionally or unexpectedly applied by another person during distribution, storage or sales display before sales.
Further, in order to remove the cover body 18 from the discharger main body 16, the protrusion 37 of the upper cylinder portion 31 must be broken, and after the protrusion 37 is broken, the second peripheral wall 35 becomes the first peripheral wall. It is unstable with respect to the body 34 and cannot be restored to the initial posture, and the purchaser can easily determine whether or not the cover body 18 has been removed from the discharger body 16.

Further, in the state where the cover body 18 is mounted on the discharger main body 16 regardless of whether it is in distribution before storage, storage or sales display, or storage after use of the contents by the purchaser, the lower cylinder portion Since the lower end of 30 is disposed on the top wall portion 17 of the mounting cap 11, the upper end of the lower cylinder portion 30 and the lower end opening edge of the surrounding cylinder portion 28 of the pressing head 14 are opposed or abutted in the vertical direction. Even if an external force that moves the pressing head 14 and the stem 12 downward is applied to the ejector 1, the force is transmitted to the mounting cap 11 via the lower cylindrical portion 30 and is received by the container body 2, The downward movement of the pressing head 14 and the stem 12 can be prevented.
Therefore, when the cover body 18 is attached to the discharger main body 16 regardless of whether it is distributed before storage, during storage or at the time of sales display, or even after storage by the purchaser, the cover body 18 is attached by the other person. The contents can be prevented from being discharged by an external force applied intentionally or unexpectedly.
Furthermore, in this embodiment, since the pressing head 14 is covered with the top part 32 of the upper cylinder part 31 also from the upper part, the unexpected discharge of the content can be prevented reliably.

  Moreover, in this embodiment, since the storage body 38 is projected toward the outer side in the radial direction at the central portion in the circumferential direction of the first peripheral wall body 34 of the upper cylindrical portion 31, the cover body is used after the contents are used. When the opening portion 30a of the lower tube portion 30 and the guide tube portion 22 of the mounting cap 11 are opposed to each other in the radial direction in order to mount the 18 to the discharger body 16 again, the tip of the discharge tube 29 It is also possible to make the inside of the storage body 38 face each other in the radial direction. As a result, when the cover body 18 and the discharger main body 16 are moved relatively close to each other in the radial direction, the guide tube portion 22 is inserted into the lower tube portion 30 while the discharge tube 29 enters the inside of the storage body 38. So that the cover body 18 can be easily attached to the discharger body 16.

  Furthermore, in this embodiment, since the radius of curvature of the inner peripheral surface of the second peripheral wall 35 is larger than the radius of curvature of the outer peripheral surface of the lower portion 28b of the surrounding cylinder portion 28 of the pressing head 14, the protrusion 37 is broken. After that, the second peripheral wall body 35 cannot be fitted and fixed to the lower portion 28b of the surrounding cylinder portion 28 of the pressing head 14. Accordingly, the second peripheral wall body 35 becomes unstable not only with respect to the first peripheral wall body 34 but also with the pressing head 14, and the initial posture of the second peripheral wall body 35 can be reliably made unrecoverable. Thus, it can be more easily determined whether or not the cover body 18 has been removed from the discharger body 16.

  Further, in the present embodiment, the upper end of the lower cylinder part 30 is close to or abuts the lower end opening edge of the surrounding cylinder part 28 of the pressing head 14 from the lower side, so that it can be distributed, stored or sold before sales. Furthermore, when the cover body 18 is attached to the discharger main body 16, regardless of whether the purchaser stores the contents after use, the pressing head is caused by an external force intentionally or unexpectedly applied by another person. It can prevent still more reliably that 14 is pushed down.

  Furthermore, in the present embodiment, the first peripheral wall body 34 includes a large-diameter portion 34b that covers the upper portion 28a of the surrounding tube portion 28 and a small-diameter portion 34c that covers the lower portion 28b of the surrounding tube portion 28. Since the outer peripheral surface of the upper portion 28a gradually protrudes outward in the radial direction from the upper end edge of the small diameter portion 34c of the first peripheral wall body 34 as it goes from the lower side to the upper side, the cover body 18 and the discharger body 16 are relatively moved. When the cover body 18 is attached to the discharger main body 16 by moving close to the radial direction, the outer peripheral surface of the upper portion 28a of the surrounding cylinder portion 28 is moved from the lower side by the upper end portion of the small diameter portion 34c of the first peripheral wall body 34. It becomes possible to support, and it can suppress that the relative position along the up-down direction of both 18 and 16 shifts | deviates.

  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, in the above-described embodiment, the guide tube portion 22 of the mounting cap 11 is shown as a portion that is externally fitted to the lower tube portion 30 in the discharger body 16, but the stem 12 may be used instead.
In the pressing head 14, the lower end opening edge of the surrounding cylinder portion 28 is shown as a portion that abuts or approaches the upper end of the lower cylinder portion 30 from the upper side, but may be the lower end opening edge of the mounting cylinder portion 27.
Further, the upper end of the lower cylinder part 30 may be separated in the radial direction or far away in the vertical direction without being brought close to or in contact with the lower ends of the surrounding cylinder part 28 and the mounting cylinder part 27 from the lower side. Good.

Further, the discharge cylinder 29 may not be provided in the pressing head 14.
Further, the storage body 38 may not be provided in the cover body 18.
The pump 13 is not limited to the above-described embodiment, and may be, for example, a so-called former pump in which an air cylinder, an air piston, or the like is added to the pump 13, or a spray pump in which an atomizing tip is provided in the discharge hole.
Moreover, although the curvature radius in the inner peripheral surface of the 2nd surrounding wall body 35 was made larger than the curvature radius in the outer peripheral surface of the lower part 28b in the surrounding cylinder part 28 of the pressing head 14, you may change suitably not only this.

Further, after the protrusion 37 of the cover body 18 is broken, the second peripheral wall 35 or the second peripheral wall 35 and the hinge portion 36 may be cut off. In this case, a weakened portion such as a thin portion that can be broken may be formed at one peripheral end of the hinge portion 36 or the first peripheral wall 34.
Further, the first plate-like body 34a may be cut off after the protrusion 37 of the cover body 18 is broken. In this case, a weakened portion such as a thin portion that can be broken may be formed at the other peripheral end portion of the first peripheral wall body 34.
Moreover, in the said embodiment, although the upper cylinder part 31 which has the top part 32 which covers the pressing head 14 from upper direction was shown, you may employ | adopt the upper cylinder part 31 which does not have this top part 32. FIG.

Further, the protrusion 37 is not limited to the above embodiment, and may be appropriately changed.
For example, a two-stage columnar body including a small diameter column portion connected to the second plate-shaped body 35a of the second peripheral wall body 35 and a hemispherical portion connected to the tip of the small diameter column portion may be employed. . And the said small diameter pillar part is inserted in the small diameter part 34d of the through-hole 34f formed in the 1st plate-shaped body 34a of the 1st surrounding wall body 34, and the said hemispherical part is arrange | positioned in the bottom face in the large diameter part 34e. Thus, when the first peripheral wall body 34 and the second peripheral wall body 35 are rotated around the hinge portion 36 so as to separate the other peripheral end portions from each other, the hemispherical portion is made large in the through hole 34f. You may make it fracture the said small diameter pillar part by hooking on the bottom face in the diameter part 34e.

  Further, the breakable protrusion 37 is shown as the connecting member, but instead, for example, the protrusion 37 is disposed in the through hole 34f of the first plate 34a, and the first plate 34a and The respective surfaces of the second plate-like body 35a are overlapped with each other, and the first plate-like body 34a and the second plate-like body 35a are separately provided on the other peripheral end portions of the first peripheral wall body 34 and the second peripheral wall body 35, respectively. For example, you may employ | adopt the structure connected through the weakened part which can be fractured, such as a thin part. That is, as the connecting member, a first plate-like body 34a and a second plate-like body 35a in which the protrusion 37 is disposed in the through hole 34f are adopted, and the first plate-like body 34a and the second plate-like body are used. The entire body 35a may be separated from the peripheral wall portion 33 by breaking the weakened portion.

Further, in this connecting member, the first plate-like body 34a is connected to the other peripheral end portion of the first peripheral wall body 34 via the weakening portion, and the second plate-like body 35a is connected to the other peripheral end portion of the second peripheral wall body 35. It may be connected to the peripheral end portion so as not to be broken without the weakened portion.
When opening, the weakened portion is broken to separate the first plate-like body 34a from the first peripheral wall body 34, the protrusion 37 is disposed in the through hole 34f, and the first plate-like body 34a and the second plate-like body 34a are separated from each other. In a state where the surfaces of the plate-like body 35a are overlapped with each other, the second peripheral wall body 35 is moved around the hinge portion 36 with respect to the first peripheral wall body 34 together with the first plate-like body 34a and the second plate-like body 35a. It may be rotated.
In this configuration, even if the first plate 34a is separated from the first peripheral wall 34, the first plate 34a may be fixed to the second peripheral wall 35 together with the second plate 35a. This makes it possible to reduce the number of discarded parts that are generated upon opening.

  In addition, it is possible to appropriately replace the constituent elements in the above-described embodiments with well-known constituent elements without departing from the gist of the present invention, and the above-described modified examples may be appropriately combined.

  It is possible to prevent the cover body from being detached from the dispenser body even if an external force is applied intentionally or unexpectedly by another person during distribution, storage or sales display, etc. before sale. It is possible to easily determine whether or not it has been removed from the product, and even after the purchaser starts using the content, the content is discharged by an unexpectedly applied external force. Can be prevented.
