Description

Technical Field

[0001] This utility model relates to the field of container packaging technology, specifically to a discharging device for a press-type container and the press-type container. Background Technology

[0002] Press-type containers are widely used in daily life because they are convenient to use and easy to dispense materials.

[0003] Prior art push-button containers typically include a bottle body, a connecting cap, a push-button pump, and a button. The push-button pump and button are fixed to the connecting cap and connected to the bottle body via the connecting cap. The external structure of prior art push-button containers can be found in [reference needed]. Figure 1 As shown, the button with a material guide channel extends to the outside of the connecting cap, so that the user can press the button to pump out the material. The pump is not shown in the figure because it is located inside the bottle and the connecting cap.

[0004] While this structure, where the button extends to the outside of the connecting cover, makes it convenient for users to press the pump to dispense materials, it is prone to accidental triggering. For example, when transporting a press-type container containing materials, accidental triggering is likely to occur. Utility Model Content

[0005] In view of the above-mentioned deficiencies of the prior art, the purpose of this utility model is to provide a discharge device for a press-type container, so as to at least partially solve the above-mentioned problems.

[0006] This utility model relates to a discharging device for a press-type container, comprising:

[0007] A discharge button mechanism includes a button body, the button body including a pressing part and a discharge channel, the pressing part being connected to the discharge channel;

[0008] The connecting mechanism includes a first connecting member and a second connecting member. The first connecting channel is formed by a channel extending in the first connecting member toward the discharge channel, and the second connecting channel is formed by a channel extending in the second connecting member toward the pressing part and sleeved on the outside of the pressing part. The first connecting channel is connected to the second connecting channel, and the first connecting channel is located in the inner layer of the second connecting channel.

[0009] A first guide component is also provided between the first connecting channel and the discharge channel, and the button body and the first connecting member can move axially relative to each other under the guidance of the first guide component;

[0010] A second guide component is also provided between the second connector and the first connector, and the second connector can move circumferentially relative to the first connector and the button body under the guidance of the second guide component;

[0011] A locking assembly is also provided between the button body and the second connector. The locking assembly includes a first locking block provided on the pressing part and a second locking block provided on the second connector.

[0012] When the second connector rotates relative to the first connector, the first locking block and the second locking block limit the relative axial movement of the button body and the first connector.

[0013] In the discharging device for the press-type container as described above, optionally, the discharging channel includes an inlet and an outlet, one end of the discharging channel having the inlet is connected to the first connecting channel, the second connecting channel is sleeved on the outside of the pressing part, and the second connecting channel is also provided with a first clearance groove to make way for the outlet.

[0014] In the discharging device for a press-type container as described above, optionally, when the second connector rotates relative to the first connector to the position where the first locking block and the second locking block abut against each other, the locking assembly limits and locks the relative axial movement of the button body and the first connector.

[0015] When the second connector rotates relative to the first connector to a position where the first locking block and the second locking block are staggered, the locking component releases the limiting lock on the button body and the first connector in the relative axial direction, and at this time the discharge port is oriented toward the first clearance groove.

[0016] In the discharging device for a press-type container as described above, optionally, the annular structure formed by folding the edge of the pressing part toward the second connector is formed by protrusions extending toward the second connector in the annular structure, which form the first locking block.

[0017] In the aforementioned discharge device for press-type containers, optionally, the discharge channel has a bent structure, and the discharge port is located on the annular structure.

[0018] In the discharging device for press-type containers as described above, optionally, a rotation limiting component is also provided between the first connecting member and the second connecting member;

[0019] The rotation limiting assembly includes a first limiting block disposed on the first connecting member and a first limiting groove disposed on the second connecting member. When the first connecting member and the second connecting member move circumferentially relative to each other, such that the first limiting block is in contact with the first side of the first limiting groove, the first locking block and the second locking block abut against each other, and the discharge port faces the position in the second connecting channel where the first clearance groove is not provided; when the first connecting member and the second connecting member move circumferentially relative to each other, such that the first limiting block is in contact with the second side of the first limiting groove, the first locking block and the second locking block are staggered, and the discharge port faces the position in the second connecting channel where the first clearance groove is provided; or

[0020] The rotation limiting assembly includes a second limiting groove on the first connecting member and a second limiting block on the second connecting member. When the first connecting member and the second connecting member move circumferentially relative to each other, causing the second limiting block to fit against the first side of the second limiting groove, the first locking block and the second locking block abut against each other. The discharge port faces the position in the second connecting channel where the first clearance groove is not provided. When the first connecting member and the second connecting member move circumferentially relative to each other, causing the second limiting block to fit against the second side of the second limiting groove, the first locking block and the second locking block are staggered. The discharge port faces the position in the second connecting channel where the first clearance groove is provided.

[0021] In the discharge device for press-type containers as described above, optionally, the first connector is further provided with a pump body connection channel, which is connected to the first connection channel.

[0022] In the discharging device for press-type containers as described above, optionally, the first connector is further provided with a bottle body connecting part, which is connected to the first connecting channel.

[0023] In the discharging device for press-type containers as described above, optionally, an anti-detachment limiting component is provided between the discharging channel and the first connecting channel to limit the relative sliding position when the discharging channel and the first connecting channel move relative to each other axially.

[0024] To achieve the above objectives, a second aspect of the present invention provides a press-type container, comprising a pump head assembly, a bottle body, and a dispensing device as described in any one of the preceding first aspects;

[0025] The discharging device is connected to the bottle body through the bottle body connecting part in the connecting mechanism. The pump head assembly is located inside the bottle body, and the pump head assembly is connected to the discharging device through the pump body connecting channel in the connecting mechanism.

[0026] This utility model provides a discharging device and a press-type container for use with press-type containers. The press-type container, by incorporating a second connecting channel sleeved on the outside of the pressing part, reduces the probability of accidental triggering, effectively minimizing the likelihood of material being accidentally pumped out during transportation due to accidental button activation. This discharging device and press-type container not only facilitate user operation but also reduce accidental triggering through the relative constraints and relationships between the structures, making it easier for users to transport the containers and possessing broad adaptability.

[0057] like Figures 2 to 4B As shown, this utility model provides a press-type container, which may include a dispensing device, a pump head assembly 3, and a bottle body 4. The dispensing device, pump head assembly 3, and bottle body 4 are detachably connected to each other.

[0058] In optional embodiments, such as Figures 2 to 5 As shown, the pump head assembly 3 may include at least a press pump 31 and a piston 32. The press pump 31 is the core component controlling the liquid flow. When the user indirectly squeezes the press pump 31 through the dispensing device, the piston 32 rises, thereby pumping the contents of the bottle 4 out through the dispensing device. However, the pump head assembly 3 can be constructed using a press pump 31 from the prior art, and this is not the focus of this invention, so it will not be described in detail here. The specific internal structure of the press pump 31 is not shown in the figure.

[0059] In actual use, such as Figures 3A to 4B As shown, the pump head assembly 3 is located inside the bottle body 4, and the pump head assembly 3 is connected to the bottle body 4 through a discharge device.

[0060] In such Figures 6A to 6D In the embodiment shown, the discharging device in the press-type container may specifically include a discharging button mechanism and a connecting mechanism 2.

[0061] In this embodiment, the discharge button mechanism includes a button body 1.

[0062] from Figures 7A to 7CIt can be seen in detail that the button body 1 may include a pressing part 11 and a discharge channel 12 connected to each other. The discharge channel 12 may include an inlet 121 and an outlet 122 that are interconnected. The inlet 121 is located in the discharge device at a position that can connect with the first connecting channel 211 in the connecting mechanism 2, so that when the connecting mechanism 2 is connected to the pressing pump 31 in the pump head assembly 3, the inlet 121 can connect with the outlet of the pressing pump 31 (see relevant structure). Figure 4B and Figure 6B (As shown), the discharge port 122 in the discharge channel 12 can be used to pump the contents to the user. Figures 7A to 7C In the illustrated embodiment, the discharge channel 12 has an "L"-shaped structure, meaning that the discharge channel 12 includes a first discharge channel and a second discharge channel that are perpendicular to and connected to each other. The inlet 121 is located at the first discharge channel, and the outlet 122 is located at the second discharge channel. The first discharge channel is coaxial with the pressing part 11, and the pressing part 11 and the discharge channel 12 are integrated into one design. In other optional embodiments, the pressing part 11 and the discharge channel 12 can also adopt other designs, as long as the pumped material can be smoothly pumped out of the discharge channel 12 when the user presses the pressing part 11.

[0063] In this embodiment, the connecting mechanism 2 may specifically include a first connecting member 21 and a second connecting member 22.

[0064] like Figure 6B , Figures 8A to 8D As shown, in this embodiment, the first connecting channel 211 is formed by the channel extending in the first connecting member 21 toward the discharge channel 12. For example... Figure 6B , Figures 9A to 9D As shown, in this embodiment, the second connector 22 extends toward the pressing part 11 and is sleeved on the outside of the pressing part 11. Figure 6A The channel shown constitutes the second connection channel 221.

[0065] like Figure 3A and Figure 4A As shown, in this embodiment, the second connector 22 is sleeved in the press-type container as a shoulder sleeve. The second connecting channel 221 in the second connector 22 is sleeved on the outside of the pressing part 11, so that if the button body 1 is to be pushed down towards the press pump 31, it is necessary to go around the top surface of the second connecting channel 221 to push the button body 1. This can reduce the problem of false triggering of the button due to external force during transportation to a certain extent.

[0066] In this embodiment, the highest point of the top surface of the second connecting channel 221 is equal to the highest point of the top surface of the button body 1 when it is not pressed. In other embodiments, the highest point of the top surface of the second connecting channel 221 may also be higher than the highest point of the top surface of the button body 1 when it is not pressed.

[0067] In this embodiment, the connecting mechanism 2 is composed of a separate first connecting member 21 and a second connecting member 22. The first connecting channel 211 in the first connecting member 21 is located within the second connecting channel 221 of the second connecting member 22, and the first connecting channel 211 and the second connecting channel 221 are coaxially arranged. Figures 3A to 3B As shown, in this example, one end of the discharge channel 12 has a feed inlet 121 that connects to the first connecting channel 211. The second connecting channel 221 is sleeved on the outside of the pressing part 11, and the second connecting channel 221 is also provided with a first clearance groove 223 to make way for the discharge port 122. The first clearance groove 223 is a recessed opening, used to provide a gap for pumping out the contents of the discharge port 122.

[0068] In an optional embodiment, a second recess 225 may be provided on the second connecting channel 221 opposite to the first recess 223, making it easier for the user to perform the pressing operation and improving the user's operating experience. The relevant structure can be found in [reference needed]. Figure 3A and Figure 3B As shown.

[0069] In this embodiment, a second guide component 213 is further provided between the second connector 22 and the first connector 21. The second guide component 213 is composed of a guide structure that rotates circumferentially around the second connecting channel 221. Under the guidance of the second guide component 213, the second connector 22 can move circumferentially relative to the first connector 21 and the button body 1, and prevent the first connector 21 and the second connector 22 from disengaging during relative rotation, so that the first connecting channel 211 and the second connecting channel 221 can rotate relative to each other. The user can rotate the outer second connecting channel 221 to produce a change in the relative circumferential position with respect to the first connecting channel 211 and the pressing part 11. Figure 4A and Figure 4B As shown, when the user is not using the container, the discharge port 122 can be rotated to the position of the second connecting channel 221 without the clearance groove, which serves to prevent dust and oxidation.

[0070] In other alternative embodiments, workers can set the clearance groove according to the actual user's desired turnover angle, and are not limited to the structure shown in the figure.

[0071] In such Figures 6D to 7B as well as Figure 8D In the embodiment shown, a first guide component 212 may also be provided between the first connecting channel 211 and the discharge channel 12. The first guide component 212 is composed of a guide structure parallel to the axis of the first connecting channel 211.

[0072] In the illustrated embodiment, the first guide component 212 includes a first groove 2121 located on the inner wall of the first connecting channel 211 and a first slider 2122 located on the outer wall of the discharge channel 12. The first groove 2121 is parallel to the axis of the first connecting channel 211, and the first slider 2122 is inserted into the first groove 2121. The first groove 2121 and the first slider 2122 cooperate with each other to ensure that the button body 1 can only move axially relative to the first connecting member 21, and cannot rotate relative to it. This effectively prevents the button body 1 from rotating with the rotation of the second connecting member 22, and at the same time ensures that the user can better press down the button body 1 to push the pump 31 to discharge material.

[0073] In alternative embodiments, the first guide assembly 212 may also consist of a slider located on the first connecting channel 211 and a groove located on the discharge channel 12 parallel to the axis of the discharge channel 12. For example... Figure 7A As shown in the figure, in this embodiment, the first slider 2122 is composed of a strip-shaped structure. However, in other embodiments, the slider may also be composed of other shapes and is not limited to the structure shown in the figure.

[0074] As described in the above embodiments, the button body 1 and the first connecting member 21 can move axially relative to each other under the guidance of the first guiding component 212. This ensures that the button body 1 and the first connecting channel 211 can only have axial relative movement and cannot rotate. When the user rotates the outer second connecting channel 221, it will not affect the orientation of the discharge port 122 in the button body 1. Thus, by controlling the orientation of the second connecting member 22, the relative position of the discharge port 122 in the button body 1 and the first clearance groove 223 in the second connecting channel 221 can be changed. When the discharge port 122 is in a position blocked by the second connecting channel 221, the position of the second connecting channel 221 without clearance groove can play a role in dust prevention and anti-oxidation. When the discharge port 122 is in a position facing the first clearance groove 223, the discharge needs can be met very conveniently.

[0075] In such Figure 3B , Figure 4B , Figure 6B , Figures 8A to 8B as well as Figures 9B to 9C In the embodiment shown, the first connector 21 further includes a pump body connection channel 214, a bottle body connection portion 215, and a second connector docking portion.

[0076] In this embodiment, the pump body connecting channel 214, the bottle body connecting part 215, the second connector docking part, and the first connecting channel 211 are integrally formed. The pump body connecting channel 214 is located at the end of the first connecting channel 211 away from the discharge channel 12, and the bottle body connecting part 215 is formed by the ring structure extending outward from the pump body connecting channel 214 and toward the button body 1. At the same time, the ring structure extending from the bottle body connecting part 215 toward the button body 1 forms the second connector docking part. That is, the bottle body connecting part 215 and the second connector docking part are located on the outer ring of the pump body connecting channel 214 and the first connecting channel 211. The pump body connecting channel 214 is designed to match the shape of the pump head assembly 3.

[0077] The second connector 22 also includes a first connector mating part, which is integrally formed with the second connecting channel 221. The first connector mating part is formed by the channel in the second connecting channel 221 extending away from the pressing part 11.

[0078] In this embodiment, the second guide assembly 213 includes a second groove 2131 located on the first connector 21 and a second slider 2132 located on the inner wall of the second connecting channel 221 of the second connector 22. The second slider 2132 is embedded in the second groove 2131 to engage and connect the first connector 21 and the second connector 22, and can rotate relative to each other. In this embodiment, the second groove 2131 is formed by an annular groove on the outer wall of the second connector mating portion of the first connector 21, and the second slider 2132 is formed by a protrusion on the inner wall of the first connector mating portion of the second connector 22.

[0079] The dispensing device is connected to the bottle body 4 via the bottle body connecting part 215, and the pressing pump 31 in the pump head assembly 3 is connected to the dispensing device via the pump body connecting channel 214.

[0080] In alternative embodiments, the second guide assembly 213 may also include a slider on the first connector 21 and an annular groove on the second connector 22, so that the first connector 21 and the second connector 22 can rotate relative to each other.

[0081] As described in the above embodiments, the second connector 22 can move circumferentially relative to the first connector 21 and the button body 1 under the guidance of the second guide component 213, and be axially limited.

[0082] In alternative embodiments, the outer wall of the first connecting channel 211 and the second connecting channel 221 may also employ a threaded and non-threaded mating design, such that the relative rotation of the first connecting channel 211 and the second connecting channel 221 primarily alters the radial circumferential angle without producing or causing linear vertical movement. Optionally, the thread may be a self-locking thread, maintaining a fixed position without external force. For example, using a special thread profile, such as a square thread or a polygonal thread, can provide greater friction during rotation, thereby reducing or preventing relative axial movement between the first connecting channel 211 and the second connecting channel 221.

[0083] To further prevent accidental triggering of button body 1, such as Figures 3A to 4B , Figure 6B , Figures 7A to 7C As shown, in an optional embodiment, a locking component may be provided between the button body 1 and the second connector 22. Specifically, the locking component may include a first locking block 111 disposed on the pressing part 11 and a second locking block 222 disposed on the second connector 22.

[0084] In this embodiment, the edge of the pressing part 11 is folded towards the second connector 22 to form an annular structure, and two first locking blocks 111 are protrusions extending downward from the annular structure at the edge of the pressing part 11.

[0085] The inner side of the second connecting channel 221 is also provided with a third connecting channel. The second connecting channel 221 and the third connecting channel are integrally formed. The two second locking blocks 222 are formed by protrusions extending in the third connecting channel toward the pressing part 11.

[0086] like Figure 4A and Figure 4B As shown, when the second connector 22 and the first connector 21 rotate relative to each other to the position where the first locking block 111 and the second locking block 222 abut against each other, the locking component limits and locks the relative axial movement of the button body 1 and the first connector 21. At this time, the button body 1 cannot be pressed down, and the container is in a locked state, which further reduces the user's accidental triggering operation.

[0087] like Figure 3A and Figure 3B As shown, when the second connector 22 and the first connector 21 rotate relative to each other to the position where the first locking block 111 and the second locking block 222 are staggered, the locking assembly releases the limiting lock on the button body 1 and the first connector 21 in the relative axial direction, and at this time the discharge port 122 is set towards the first clearance groove 223, the button body 1 can be pressed down freely in the axial direction, and the container is in the unlocked state.

[0088] In summary, the second connector 22 achieves rotation relative to the button body 1 through its relative rotation with the first connector 21, providing a switching between a locked and unlocked state for the container. Simultaneously, as mentioned earlier, the first connector 21 can restrict the rotation of the button body 1 via the first guide component 212 and can guide it axially, ensuring that the button body 1 can only be pressed up and down axially within the inner layer of the second connector 22 in the unlocked state. This design ensures the safety of the container during transportation, assembly, or daily life, preventing accidental release of the contents due to accidental triggering of the button body 1.

[0089] like Figure 7A and Figure 7C As shown, in this embodiment, the annular structure formed by the edge of the pressing part 11 folding towards the second connector 22 forms the first locking block 111, which is formed by a protrusion extending towards the second connector 22 in the annular structure. In this embodiment, the discharge channel 12 has a bent structure, and the discharge port 122 is opened on the annular structure. The entire surface of the pressing part 11 of the button body 1 is pressable.

[0090] The annular structure design with the downward-curving edge of the pressing part 11 can better disperse the force on the button body 1. At the same time, a reinforcing rib is also provided at the position where the first locking block 111 is located inside the button body, which can further increase the rigidity and bending resistance of the first locking block 111 in the dispensing button mechanism. That is, when the force of the user pressing the button body 1 is applied to the pressing part 11, the force will be transmitted along the material of the pressing part 11 due to the continuity and uniformity of the material. Since the pressing part 11 and the annular structure are integrally connected, the force can be effectively dispersed to the surrounding structure in the radial and axial directions, which can achieve a more uniform stress distribution.

[0091] The above structural design can also bring the following beneficial effects:

[0092] When assembling the discharge device, pump head assembly 3, and bottle body 4 on a factory assembly line, the components of the discharge device, pump head assembly 3, and bottle body 4 are usually assembled sequentially.

[0093] During installation, the press pump 31 in the pump head assembly 3 can be installed in the pump body connection channel 214 in the first connector 21 first, and then the second connector 22 and the button body 1 can be fixedly connected to the first connector 21. Then the installed related structures can be fixedly connected to the bottle body 4.

[0094] To facilitate production, the relevant structures use a snap-fit ​​connection structure to connect the relevant components. This means that the connection between the button body 1 and the first connector 21, the connection between the first connector 21 and the second connector 22, and the connection between the first connector 21 and the bottle body 4 all require a large force to complete the connection of the relevant structures.

[0095] However, if the button body 1 in the existing technology is used for related installation, the force applied to the button body 1 will be directly transmitted to the press pump 31 installed on the first connector 21, causing damage to the press pump 31.

[0096] Meanwhile, since the press pump 31 must be installed on the dispensing device to connect with the bottle body 4, in the prior art, to avoid the press button triggering the press pump 31 and causing the contents to be pumped out, the force is usually applied only to the shoulder sleeve formed by the second connector 22 for installation. This results in the second connector 22 having to be subjected to a large force to achieve smooth assembly. However, making the second connector 22 thinner increases industrial difficulty, as the pressure head on the production equipment needs to precisely press against the narrow top surface of the second connector 22; while making the second connector 22 thicker also increases the manufacturing difficulty of the part itself, requiring more material and restricting the appearance design.

[0097] The locking component in this application effectively solves the above problems. During the production process, the first locking block 111 on the pressing part 11 can be aligned with the second locking block 222 on the second connecting member 22. Then, the production equipment can avoid applying downward pressure to the pressing pump 31, which would cause the contents to be pumped out. At the same time, the top surfaces of the button body 1 and the second connecting member 22 can be pressed simultaneously. This allows the force applied during installation to be transmitted from the button body 1 to the second connecting member 22 through the locking component without adjusting the thickness of the second connecting member 22 when the dispensing device is connected to the bottle body 4. This effectively provides a larger pressing area and makes production easier. In addition, the shoulder sleeve formed by the second connecting member 22 can be selected with a thin or thick shape as needed.

[0098] This invention provides a discharge device for press-type containers, which effectively solves the above problems. The discharge device provided by this invention can withstand greater forces during the assembly of the pump head assembly 3 in container production, thus optimizing production efficiency and product quality.

[0099] In optional embodiments, such as Figures 8D to 9D As shown, a rotation limiting component can also be provided between the first connecting member 21 and the second connecting member 22 to position and limit the rotation angle in the container, thereby realizing the opening and closing position corresponding to the discharge port 122.

[0100] Specifically, the rotation limiting assembly may include a first limiting block 216 disposed on the first connecting member 21 and a first limiting groove 224 disposed on the second connecting member 22. When the first connecting member 21 and the second connecting member 22 move circumferentially relative to each other, such that the first limiting block 216 is in contact with the first side 2241 of the first limiting groove, the first locking block 111 and the second locking block 222 are in contact, the discharge port 122 faces the position in the second connecting channel 221 where the first clearance groove 223 is not provided, the container is in a locked state, the downward action of the limiting button body 1 is stopped, and the contents are prevented from being pumped out. Similarly, when the first connector 21 and the second connector 22 move in a relative circumferential direction, causing the first limiting block 216 to fit against the second side 2242 of the first limiting groove, the first locking block 111 and the second locking block 222 are staggered, the discharge port 122 faces the position where the first clearance groove 223 is set in the second connecting channel 221, the container is in the unlocked state, the button body 1 can be freely pressed axially, and the contents in the container can be smoothly pumped out.

[0101] The rotation limit component can provide a prompt indicating that it has been rotated to the correct position, making it easier for the user to adjust it to the desired position. In this embodiment, the first limiting groove 224 is formed by a groove at the bottom of the third connecting channel in the second connector 22, and the first limiting block 216 is formed by a protrusion on the first connector 21.

[0102] In optional embodiments, the rotation limiting assembly may include a second limiting groove on the first connector 21 and a second limiting block on the second connector 22. When the first connector 21 and the second connector 22 move circumferentially relative to each other, causing the second limiting block to fit against the first side of the second limiting groove, the first locking block 111 and the second locking block 222 abut against each other. The discharge port 122 faces the position in the second connecting channel 221 where the first clearance groove 223 is not provided, and is in a locked state, limiting the downward action of the button body 1 and preventing the contents from being pumped out. When the first connector 21 and the second connector 22 move circumferentially relative to each other, causing the second limiting block to fit against the second side of the second limiting groove, the first locking block 111 and the second locking block 222 are staggered, and the discharge port 122 faces the position in the second connecting channel 221 where the first clearance groove 223 is provided, allowing the contents in the container in the unlocked state to be pumped out smoothly.

[0103] In this embodiment, the dispensing device and the bottle body 4 can be detachably connected by a snap-fit ​​mechanism. Specifically, the bottle body connecting part 215 is connected to the first connecting channel 211.

[0104] In this embodiment, the outer side of the bottle body connecting part 215 is provided with a ribbed structure, and a corresponding groove is provided on the inner wall of the bottle body 4, with the ribbed structure and the groove being interlocked. In other optional embodiments, a groove design can also be used at the bottle body connecting part 215, and a ribbed structure can be provided on the inner wall of the bottle body 4 to achieve an interlocking connection between the dispensing device and the bottle body 4.

[0105] In other optional embodiments, the dispensing device and the bottle body 4 can also be installed by means of threaded connection. For example, corresponding internal and external threads are provided on the outer side of the bottle body connection part 215 and the inner side of the bottle body 4, and the dispensing device and the bottle body 4 are installed by rotating and tightening.

[0106] like Figure 6B , Figures 7A to 7C As shown, in an optional embodiment, an anti-detachment limiting component may be provided between the discharge channel 12 and the first connecting channel 211. This anti-detachment limiting component may include a first limiting ring 217 located on the first connecting channel 211 and a second limiting ring 218 located on the discharge channel 12 of the button body 1. The first limiting ring 217 and the second limiting ring 218 abut against each other to limit the relative sliding position of the discharge channel 12 and the first connecting channel 211 during relative axial movement, preventing the button body 1 from detaching from the connecting mechanism 2, and appropriately increasing the damping sensation when the user presses down on the button body 1. In other optional embodiments, other structures may be used to construct the anti-detachment limiting component, such as replacing at least one limiting ring with a limiting block.

[0107] By designing the anti-detachment limiting component, not only can the button body 1 be prevented from falling off the first connector 21 during the pressing process, but it also helps to prevent relative movement between the discharge channel 12 and the first connecting channel 211 caused by accidental impact or vibration, thereby protecting the container from damage.

[0108] In summary, the discharging device and the press-type container described in the above embodiments are not only convenient for users, but also reduce the possibility of accidental triggering through the relative constraints and relationships between the structures, making it easier for users to transport the relevant containers and having wide adaptability.

[0109] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
