Detailed Description
The discharge container 1 which can be discarded separately according to one embodiment of the present invention will be described below.
Fig. 1 is a cross-sectional view of the entire discharge container 1, and fig. 2 is an enlarged cross-sectional view of an upper portion of the discharge container 1. Fig. 3 is a perspective view of the pump unit 20.
As shown in fig. 1, the discharge container 1 of the present embodiment includes: a container 10, wherein the container 10 is provided with a neck-shaped portion 12 around an opening 11; a pump unit 20, the pump unit 20 ejecting the content of the container 10; and a fixing member 30, the fixing member 30 fixing the pump unit 20 to the neck-shaped portion 12 of the container 10. The pump unit 20 and the holder 30 constitute a content ejection unit that ejects the content in the container 10.
As shown in fig. 2 and 3, the pump unit 20 includes: a cylinder 21, a lower portion of the cylinder 21 being inserted into the opening 11 of the container 10; a piston 22, a tip 22a of the piston 22 being inserted into the cylinder 21; and a button 23, the button 23 being fixed to the rear end 22b of the piston 22.
Elastic members (here, double springs 24a and 24 b) are disposed around the piston 22, and support the piston 22 while biasing the cylinder 21.
A through hole 21b is provided at the top end (lower end) of the cylinder 21, and the through hole 21b is covered with a check valve 21 c. A tube 21d for sucking up the content of the container 10 is inserted into the through hole 21 b. Further, a cylinder inner tube 21e is fixed to the upper end of the cylinder 21.
The button 23 is provided with a discharge port 25. Here, piston outer cylinders 22c, 22d are disposed around the piston 22 so as to surround the piston 22, and the piston 22 is fixed to the push button 23 via the piston outer cylinder 22 c. A minute gap 22e is provided between the outer peripheral surface of the piston 22 and the piston outer cylinders 22c, 22d, and the gap 22e serves as a flow path for guiding the content of the container 10 from the space 21a of the cylinder 21 to the push button 23.
The piston outer tube 22c isolates the springs 24a and 24b from the piston 22, and the springs 24a and 24b are not in contact with the content of the container 10.
The button 23 is provided with a flow path 23a for guiding the content reaching through the gap 22e of the piston 22 to the discharge port 25.
A support ring 26 is fixed to the upper end of the cylinder 21 via a cylinder inner tube 21 e. The support ring 26 has a shape that covers the outer periphery of the neck-shaped portion 12 in an annular shape from the edge of the opening 11. The support ring 26 is connected to the cylinder inner tube 21e and the outer circumferential surface of the cylinder 21 at the upper portion of the edge of the opening 11, and supports the cylinder 21 above the edge of the opening 11. Here, a seal 27 is arranged between the support ring 26 and the edge of the opening 11.
In the neck-shaped portion 12 of the container 10, the rim 12a extends outward in an annular shape, and a recess 12b (radial depth a) is provided at a lower portion of the rim 12 a. A convex portion 26a (height B in the radial direction (B < a)) that engages with the concave portion 12B on the inner peripheral surface side is provided at the lower end of the support ring 26.
The fixing member 30 includes a fastening ring 31 having an inner peripheral surface in contact with an outer peripheral surface of the support ring 26, and a fixing ring 32 disposed outside the fastening ring 31. The fastening ring 31 and the fixing ring 32 are provided with a locking mechanism 40 for fixing the support ring 26 to the neck-shaped portion 12.
Here, as an example, the lock mechanism 40 includes a convex portion 26c (or concave portion) provided on the outer peripheral surface of the support ring 26 and a concave portion 31c (or convex portion) provided on the inner peripheral surface of the fastening ring 31 at a position corresponding to the convex portion 26c (or concave portion). The locking mechanism 40 is locked by engagement of the convex portion 26c (or concave portion) of the support ring with the concave portion 31c (or convex portion) of the inner peripheral surface of the fastening ring 31. Further, a pressing protrusion 31d is provided on the outer peripheral surface of the fastening ring 31 at the same position as the recess 31 c. The fixing ring 32 is disposed so as to contact with the pressing projection 31d of the fastening ring 31, and the fastening ring 31 is pressed against the support ring 26 and is swaged, so that the projection 26c and the recess 31c are firmly engaged to maintain the locked state, and the support ring 26 is fixed to the neck-shaped portion 12.
On the other hand, as shown in fig. 3, the support ring 26 is provided with 1 or more cutouts 26b in the axial direction. By providing the slit 26b, the support ring 26 is deformed and contracted in the radial direction when being swaged by the fastening ring 31, and is firmly fixed to the neck-shaped portion 12.
In the present embodiment, the concave portion 31c, the convex portion 26c, and the pressing convex portion 31d are provided in a ring shape along the circumferential direction of the inner circumferential surface of the fastening ring 31 and the outer circumferential surface of the support ring 26.
To describe each part of the lock mechanism 40 in more detail, the pressing convex portion 31d contacts the fixing ring 32, so that the fastening ring 31 is pressed against the support ring 26, and the pressing convex portion 31d presses the concave portion 31c and the convex portion 26c into engagement, thereby increasing the strength of the caulking support ring 26. Further, since the convex portion 26c of the support ring 26 is fitted into the concave portion 31c of the fastening ring 31, the support ring 26 cannot move axially upward. Thereby, the lock mechanism 40 suppresses the support ring 26 from being disengaged from the neck-shaped portion 12.
The lower end of the fastening ring 31 is located at the same height as the lower end of the support ring 26, and includes a projection 31a (radial height C) projecting toward the inner peripheral surface side. Accordingly, the projection 26a at the lower end of the support ring 26 is thicker than the distance between the projection 31a of the fastening ring 31 and the neck-shaped portion 12, and the support ring 26 cannot pass through the space between the projection 31a of the fastening ring 31 and the neck-shaped portion 12. Thus, a configuration is achieved in which the support ring 26 is further firmly prevented from moving axially upward.
In this way, the support ring 26 is fixed to the neck-shaped portion 12 by being not only pressed against the neck-shaped portion 12 by the fastening ring 31 by the locking mechanism 40, but also prevented from moving in the axial direction.
On the other hand, an engagement portion 28 that engages with the fastening ring 31 at a predetermined angle when the button 23, the piston 22, or the piston outer tube 22c is rotated about its axis is provided in a part of any one of the button 23, the piston 22, and the piston outer tube 22 c.
Here, as shown in fig. 4 (a), an example will be described in which the engaging portion 28 is provided at the lower end of the outer peripheral surface of the button 23. The button 23 is rotatably attached to the piston 22 and the piston outer tube 22c about an axis, and the button 23 includes a first projection (hereinafter referred to as a first projection 28) projecting outwardly from the lower end of the outer peripheral surface of the button 23 as an engaging portion 28 (see fig. 4 b).
As shown in fig. 2, the fastening ring 31 has a height reaching above the opening 11 of the container 10. As shown in fig. 5 (a) and (b), a second projection 29 having a shape capable of engaging with the first projection 28 is provided on the inner peripheral surface of the fastening ring 31 above the opening 11.
Therefore, when the user rotates the button 23 as shown in fig. 6 (a-1) and (a-2), and presses the button 23 in this state with the first projection 28 engaged with the second projection 29 as shown in fig. 6 (b-1) and (b-2), the fastening ring 31 is pushed out axially downward from between the support ring 26 and the fixing ring 32 (see fig. 6 (a-2) and (b-2)).
As a result, as shown in fig. 7, the concave portion 31c of the fastening ring 31 is displaced in the axial direction beyond the engagement with the convex portion 26c of the support ring 26, and thus the engagement state is released. At the same time, since the pressing protrusion 31d at the same position as the concave portion 31c of the fastening ring 31 moves to the position of the concave portion 12b below the edge portion 12a of the neck-shaped portion 12, even if the pressing protrusion 31d comes into contact with the fixing ring 32, since the support ring 26 is not located inside the position, the caulking force applied to the support ring 26 by the fixing ring 32 is released from the support ring 26. As a result, as shown in fig. 6 (c), the fixing ring 32 can be removed upward, and the support ring 26 can be removed from the neck-shaped portion 12 of the container 10.
This allows the pump unit 20 after use to be detached from the container 10 and discarded separately.
Further, since the fastening ring 31 is attached to the detached pump unit 20 in a state of being lowered downward, even if the fixing ring 32 is covered, the support ring 26 cannot be swaged by the fastening ring 31, and the pump unit 20 cannot be fixed to the container 10 again. This allows the contents of the container 10 to be replaced, preventing the pump unit 20 from being fixed again and reused, and ensuring the quality of the contents of the discharge container 1.
Here, the engaging portion 28 is further described.
As shown in fig. 4 (b) and 5 (a), the first protrusions 28 of the engaging portion are provided in plural at regular intervals (here, at intervals of 90 degrees) in the circumferential direction of the outer peripheral surface of the push button 23, and the second protrusions 29 are provided at positions corresponding to the first protrusions 28 on the inner peripheral surface of the fastening ring.
The first and second protrusions 28, 29 each have a recess 29a in the circumferential direction, and one (here, the second protrusion 29) has a shape (here, a diamond shape) that fits into the recess 29a so as to be able to engage with each other.
The first and second protrusions 28 and 29 are preferably formed as follows: when the button 23 is rotated, as shown in fig. 6 (a-1) and 6 (b-1), the first projection 28 is inserted into and fitted into the recess 29a of the second projection 29 at a certain rotation angle, and when the button 23 is rotated further, the first projection 28 is disengaged beyond the recess 29a of the second projection 29. Specifically, for example, the cross-sectional shape of the first protrusion 28 parallel to the outer peripheral surface of the button is preferably a diamond shape having a size capable of being inserted into the recess 29a of the second protrusion 29. Thus, when the button 23 is rotated to move the diamond-shaped first protrusions 28 in the circumferential direction, the protrusions can be easily inserted into the recesses 29a regardless of the rotation direction, and the protrusions can be easily removed from the recesses 29a by further rotation.
By configuring in this way, the first projection 28 and the second projection 29 are changed from the disengaged state to the engaged state and from the disengaged state again as the button 23 is rotated, and even when the user rotates the button 23 during use to engage the first projection 28 with the second projection 29, the button 23 can be easily restored to the use state by further rotating the button. Thereby, erroneous removal of the pump unit 20 from the container 10 during use can be suppressed.
In addition, the bottom surface shape of the second projection 29 provided on the axially lower side of the fastening ring 31 is preferably inclined with respect to the circumferential direction of the fastening ring 31. For example, as shown in fig. 5 (b) and 6 (a-1), the second projection 29 is preferably formed in a diamond shape with a recess 29a cut out from the upper surface in a cross section parallel to the inner peripheral surface of the fastening ring 31.
By forming such a shape, after the pump unit 20 is mounted to the neck-shaped portion 12 of the container 10 at the time of manufacture, when the fastening ring 31 is pressed into the outside of the support ring 26 from above, as shown in fig. 8 (a) to (c), even in the case where the second projection 29 is in a positional relationship pressed from directly above the first projection 28, the lower surface of the second projection 29 is inclined, and therefore the bottom surface of the second projection 29 moves so as to retreat in the circumferential direction as to slide on the upper surface of the first projection 28. This can prevent the first projection 28 or the second projection 29 from being broken during manufacturing. The yield can be improved.
The material of the fixing ring 32 is preferably a material which is not easily deformed, and is preferably metal or glass other than resin. The material of the support ring 26 is preferably resin or metal so as to be deformable. The material of the fastening ring 31 may be any material that can lock the movement of the support ring 26 by engaging the support ring 26 with the projections and depressions, and can release the locking by moving over the projections and depressions by pressing the button 23, and for example, resin or metal can be used. As the resin of each of the above components, polypropylene and polyethylene can be used.
Further, by providing grooves in the inner peripheral surface of the fixing ring 32 in the axial direction, the fastening ring 31 can be smoothly pressed down in the axial direction.
Here, a series of operations of each portion of the ejection container 1 in use and of the pump unit 20 after use in removal will be described.
In use, when the user presses the button 23, the piston 22 is pressed in the direction of the compression springs 24a, 24b, the tip 22a of the piston 22 compressing the space 21a within the cylinder 21.
After that, when the user releases his hand from the button 23, the springs 24a and 24b are extended and restored to their original positions, so that the space 21a of the cylinder 21 is depressurized, and the contents of the container 10 fill the space 21a in the cylinder 21 through the pipe 21d and the through hole 21 b. The check valve 21c prevents the reverse flow of the content in the space 21a and returns to the container 10.
When the user presses the button 23 again, the piston 22 is pressed in the direction of the compression springs 24a and 24b, and when the space 21a filled with the content is compressed, the pressure in the space 21a increases, and the content in the space 21a in the cylinder 21 reaches the button 23 through the gap between the piston 22 and the piston outer tube 22c, and is discharged from the discharge port 25a through the flow path 23a in the button.
If the entire content is discharged without the content, the user removes the pump unit 20 from the container 10 in order to separate and discard the discharge container 1. Specifically, first, as shown in fig. 6 (a-1) and (a-2), the user rotates the button 23 to align and fit the first protrusion 28 on the outer periphery of the button 23 with the recess 29a of the second protrusion 29 of the fastening ring 31 (fig. 6 (b-1) and (b-2)).
In this state, when the user pushes the button 23 downward, the fastening ring 31 is pushed downward, and the fastening ring 32 is not applied with a caulking force to the support ring 26 from the fixing ring 32, so that the fixing ring 32 can be detached upward as shown in fig. 6 (c). After the user removes the fixing ring 32 upward, the pump unit 20 is removed from the container 10 with the fastening ring 31 attached.
This allows the container 10 to be separated and discarded even when the material of the container and the material of the pump unit are different.
In addition, in order to separate, the pressing operation of the button 23 requires a force larger than the force pressing the button 23 at the time of use, but the button 23 is originally made in a pressing manner, and the force of the user can be efficiently transmitted to the fastening ring 31. Further, since the fastening ring 31 is pushed downward while maintaining the shape, the fastening ring 31 can be pushed down with a smaller force than in the case of breakage, and the pump unit 20 can be detached.
As described above, according to the present embodiment, it is possible to provide the discharge container 1 in which the pump unit 20 is detached from the container 10 with a small force after the content is used.
In the above embodiment, the description has been made of the structure in which the annular convex portion 26c is provided in the support ring 26, the annular concave portion 31c is provided in the fastening ring 31, and the fastening ring 31 is pressed down over the concave-convex portion by pressing down the push button 23 to release the lock, as the lock mechanism 40, but the present invention is not limited to such a lock mechanism 40. Any structure may be used as long as the mechanism can be unlocked by pressing the button 23. For example, the fastening ring 31 may be a structure such as a pin, not a ring, and may be a structure that engages with the support ring 26 to be locked. In this case, by forming a structure in which the pin is released from engagement with the support ring 26 in response to the push of the button 23, a mechanism in which the lock is released by the push of the button 23 and the pump unit 20 can be removed can be realized.
