[0006] Technical issues
[0007] In the aforementioned discharge container, for the purpose of facilitating the separate disposal of the discharger and the container body, or for reusing the discharger by removing it from the container body after use and installing it into another container body, it is considered that the discharger body be configured to be detachable by unscrewing the threads from its threaded connection to the container body. However, in this case, for example, if a cover that can be rotated and removed is provided on the discharger body, it is possible that rotating along with the cover could cause the threads of the discharger body to loosen unexpectedly from the container body.
[0008] Therefore, the object of the present invention is to provide a discharge container that can prevent the discharger body from accidentally loosening from the container body, while allowing the discharger body to be easily disassembled as needed.
[0009] Technical solution
[0010] One embodiment of the present invention is described below. [1]
[0012] A discharge container, characterized in that,
[0013] The device comprises a container body and a discharge device. The container body has a mouth peripheral wall and a locking portion. The discharge device has a discharge device body and an anti-rotation portion, the anti-rotation portion having a locking portion.
[0014] The discharge device body can be disassembled from its threaded engagement position relative to the peripheral wall of the opening by unscrewing the threads at the usage position for discharging the contents of the container body.
[0015] When the ejector body is in the use position, the anti-rotation part can move between an engaged position where the engaging part is engaged with the engaged part and a non-engaged position where the engaging part is not engaged with the engaged part, at least from the engaged position to the non-engaged position, depending on the axial operation of the peripheral wall of the opening. The engaged position restricts the rotation of the ejector body relative to the peripheral wall of the opening in the direction of thread loosening. [2]
[0017] The discharge container according to [1] is characterized in that,
[0018] The discharge device has a cover that can be detached from the discharge device body by unscrewing the threads in the same direction as the direction in which the discharge device body is unscrewed relative to the peripheral wall of the opening. [3]
[0020] The discharge container according to [1] or [2] is characterized in that,
[0021] The main body of the discharge device includes a mounting sleeve, and it can be disassembled from the use position by unscrewing the threads relative to the peripheral wall of the opening via the mounting sleeve.
[0022] The anti-rotation part is connected to the mounting cylinder, which restricts relative rotation to both sides in the circumferential direction and allows relative movement to both sides in the axial direction. [4]
[0024] According to the discharge container described in [1] to [3], the characteristic is that,
[0025] The main body of the discharge device has an abutment portion and can be installed in a temporary holding position relative to the peripheral wall of the opening.
[0026] By moving the discharge device body from the temporary holding position to the use position, the abutment portion moves radially inward toward the inside of the container body on the peripheral wall of the opening and abuts against the sealing member of the container body, thereby opening the container body.
[0027] The discharger has a stop that can be removed from the opening restriction position, which is a position that restricts the discharger body from moving from the temporary holding position to the use position.
[0028] Invention Effects
[0029] According to the present invention, a discharge container can be provided that can prevent accidental loosening of the discharger body from the container body by threads, and the discharger body can be easily disassembled as needed. Attached Figure Description

[0034] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
[0035] like Figures 1 to 2 As shown, in one embodiment of the present invention, the discharge container 1 includes a container body 2 and a discharger 3. The container body 2 includes an opening peripheral wall 2a and a locking portion 2b. The discharger 3 includes a discharger body 3a and an anti-rotation portion 3b, and the anti-rotation portion 3b includes a locking portion 4. The opening peripheral wall 2a is formed in a cylindrical shape with the central axis O as the center.
[0036] It should be noted that in this embodiment, the axial direction is along the central axis O, the radial direction is the direction orthogonal to the central axis O, the circumferential direction is the direction around the central axis O, and the longitudinal section is a cross-section including the central axis O. For ease of explanation, the direction along the axial direction from the peripheral wall 2a of the opening towards the interior of the container body 2 is referred to as downward, and its opposite direction is referred to as upward.
[0037] The body 3a of the discharge device can be installed relative to the peripheral wall 2a of the inlet by means of a threaded connection. Figure 2 The shown position is for discharging the contents of the container body 2 and can be disassembled from the threaded state by unscrewing the threads at the position of use.
[0038] When the discharger body 3a is in the use position, the anti-rotation part 3b allows the engaging part 4 to move axially between an engaged position and a non-engaged position along the peripheral wall 2a of the opening by sliding the anti-rotation part 3b in the axial direction, at least from the engaged position to the non-engaged position. Figure 2The position indicated by the double-dotted line, where the engaging part 4 and the engaged part 2b are engaged through the interlocking of their protrusions and recesses, is used to restrict the rotation of the discharger body 3a relative to the peripheral wall 2a of the opening in the direction of thread loosening. This non-engaged position is... Figure 2 The position where the engaging part 4 and the engaged part 2b are not engaged is shown in solid line.
[0039] With this structure, when the discharger body 3a is in the use position, by configuring the anti-rotation part 3b in the engaged position, it is possible to prevent the discharger body 3a from accidentally loosening its threads from the container body 2.
[0040] In addition, when separating the discharge device 3 from the container body 2, and when it is necessary to remove the discharge device body 3a from the port peripheral wall 2a, with the discharge device body 3a in the use position, the anti-rotation part 3b is slid upward to move it to the non-locking position, and then rotated in the direction of unscrewing the thread, so that the discharge device body 3a can be easily removed by unscrewing it from the port peripheral wall 2a.
[0041] It should be noted that, as the structure of the engaged part 2b and the engaged part 4, a structure can be adopted in which, for example, when the discharger body 3a is in the use position and the anti-rotation part 3b is in the engaged position, the engaged part 4 is engaged relative to the engaged part 2b in the same rotational direction as the loosening of the threads of the discharger body 3a, and the engagement is performed via the ratchet part.
[0042] When the discharger body 3a is in the use position, the anti-rotation part 3b can be moved from the engaged position to the disengaged position by sliding the anti-rotation part 3b upward, and can be moved from the disengaged position to the engaged position by sliding the anti-rotation part 3b downward.
[0043] With this structure, when the discharger 3 is replaced with another container body 2, by positioning the discharger body 3a in the use position and sliding the anti-rotation part 3b downwards to move it from the non-engaged position to the engaged position, the discharger body 3a is installed on the port peripheral wall 2a, ensuring that the discharger body 3a will not accidentally loosen from the container body 2. Furthermore, the structure of the engaged part 2b and the engaged part 4 is not limited to the ratchet portion described above. For example, when the discharger body 3a is in the use position and the anti-rotation part 3b is in the engaged position, a structure in which the relative rotation of the two sides of the circumferential direction of the engaged part 2b and the engaged part 4 is mutually restricted (e.g., via a spline portion) can be used for engagement. However, the anti-rotation part 3b is not limited to this structure.
[0044] like Figure 1As shown, the discharger 3 has a cover 3c, which can be removed from the discharger body 3a by unscrewing the second threaded connection 6. The rotation direction of the unscrewing thread of the second threaded connection 6 is the same as the direction of the unscrewing thread of the discharger body 3a relative to the opening peripheral wall 2a.
[0045] Based on this structure, the discharger body 3a is located at Figure 2 When in the indicated position, as long as the anti-rotation part 3b is in the engaged position, the discharger body 3a will not rotate together. Therefore, the cover can be easily attached to or detached from the discharger body 3a by screwing on and unscrewing the cover 3c.
[0046] However, the structure of the cover 3c is not limited to this. Alternatively, it can also be a structure that does not have a cover 3c.
[0047] The discharger body 3a has a mounting sleeve 7a, which can be unscrewed from the use position to remove the discharger body 3a from the port peripheral wall 2a. The anti-rotation part 3b is connected to the mounting sleeve 7a, for example, via a spline part. The anti-rotation part 3b is restricted from relative rotation to both sides in the circumferential direction and is allowed to move relative to both sides in the axial direction.
[0048] Based on this structure, as described above, when the discharger body 3a is in the use position, the anti-rotation part 3b can be moved from the engaged position to the disengaged position by sliding the anti-rotation part 3b upwards, and can be moved from the disengaged position to the engaged position by sliding the anti-rotation part 3b downwards. However, the structure of the discharger body 3a and the anti-rotation part 3b is not limited to this.
[0049] The discharge body 3a can be installed relative to the port peripheral wall 2a at... Figure 1 In the temporary holding position shown, the discharger body 3a has an abutment portion 7b. By moving the discharger body 3a from the temporary holding position to the use position, the abutment portion 7b moves radially inward toward the inside of the container body 2 on the peripheral wall 2a of the opening and abuts against the sealing member 2c of the container body 2, thereby enabling... Figure 2 The container body 2 is opened as shown. Additionally, the discharge device 3 is equipped with... Figure 1 The stop portion 3d shown is, for example, C-shaped when viewed axially and capable of elastic deformation. The stop portion 3d can be adjusted from... Figure 1 The opening restriction position shown is removed; this opening restriction position is used to prevent the discharger body 3a from moving from the temporary holding position to the use position (e.g., by means of...). Figure 1 As shown, it is positioned axially between the anti-rotation part 3b and the container body 2.
[0050] With this structure, the stop 3d can prevent accidental opening of the container body 2. Furthermore, after removing the stop 3d from the opening restriction position, the container body 2 can be opened and made usable by a simple operation of moving the discharger body 3a from the temporary holding position to the use position. However, the structure of the discharge container 1 is not limited to this.
[0051] The sealing member 2c is a sheet-like structure that closes the peripheral wall 2a of the opening. The abutting part 7b abuts against the sealing member 2c, causing the sealing member 2c to rupture and open the container body 2. This structure simplifies the construction. However, the structure of the discharge container 1 is not limited to this.
[0052] The sealing component 2c is integrally disposed with the innermost layer body disposed on the innermost side of the container body 2. With this structure, by forming the innermost layer body from materials such as aluminum, the functions of barrier properties, light-blocking properties, etc., can be effectively improved by utilizing the innermost layer body.
[0053] The discharger body 3a includes a valve body 8a that allows flow out of the container body 2 and prevents backflow. With this structure, the contents of the container body 2 are less likely to be exposed to outside air during use, thus maintaining the quality of the contents effectively. However, the structure of the discharger body 3a is not limited to this.
[0054] The discharger body 3a has an assembly structure comprising: a mounting component 7 having a mounting cylinder 7a and an abutment portion 7b and being threaded to a cover 3c via a second threaded connection portion 6; a sealing member 9, which is axially clamped between the mounting component 7 and the port peripheral wall 2a when the discharger body 3a is in the use position; a valve component 8 having a valve body 8a; and a nozzle component 10 having a discharge port 10a. It should be noted that the mounting component 7, valve component 8, nozzle component 10, and anti-rotation portion 3b are each formed of, for example, synthetic resin.
[0055] The container body 2 is configured, for example, as a tubular container capable of extruding contents, and is elastically deformable by receiving a pressing operation for discharging the contents. The discharger body 3a is configured to have a discharge cap having a discharge port 10a for discharging contents by pressing the container body 2. However, the structure of the discharge container 1 is not limited to this. For example, it may also be configured as a pump device for discharging contents according to the operation of the discharger body 3a.
[0056] This invention is not limited to the above-described embodiments, and various modifications can be made without departing from its spirit.
[0057] Therefore, the discharge container 1 of the above embodiment can be modified as long as it has the following features. These features are: it has a container body 2 and a discharger 3; the container body has an opening peripheral wall 2a and a locking portion 2b; the discharger 3 has a discharger body 3a and an anti-rotation portion 3b; the anti-rotation portion 3b has a locking portion 4; the discharger body 3a can be disassembled from the threaded engagement state by unscrewing the threads relative to the opening peripheral wall 2a in the use position for discharging the contents of the container body 2; when the discharger body 3a is in the use position, the anti-rotation portion 3b can move between the locking position where the locking portion 4 is engaged with the locking portion 2b and the non-locking position where the locking portion 4 is not engaged with the locking portion 2b, at least from the locking position to the non-locking position, depending on the axial operation of the opening peripheral wall 2a; the locking position restricts the discharger body 3a from rotating relative to the opening peripheral wall 2a in the direction of thread loosening.
