Description
Technical Field
[0001] This utility model relates to the field of fluid container technology, and in particular to a daily chemical product and its packaging container and replacement bottle. Background Technology
[0002] With the improvement of living standards, the cosmetics market is also expanding. Common cosmetics such as serums, face creams, foundations, and eye creams often use airless bottles to prevent contact with air, avoid oxidation and contamination, and extend shelf life. Existing vacuum bottles install the inner bottle inside the outer packaging shell, with the inner bottle tightly secured to the outer shell. When the fluid in the inner bottle is used up, it is often discarded as a whole, resulting in resource waste. With increasing social awareness of environmental protection, the concept of refills is becoming more widespread in the cosmetics market, and companies are adapting to the needs of conservation and environmental protection through improvements to packaging containers.
[0003] Existing vacuum bottles require multiple presses to expel air during initial use. Improper operation may lead to difficulty in dispensing liquid, and users may mistakenly believe that the product is "not full or has quality problems." Some vacuum bottles may experience leakage or failure to press (liquid cannot be pumped out) due to piston design defects or spring aging, affecting the user experience.
[0004] Patent document CN211996924U discloses a cosmetic vacuum bottle with an easily replaceable inner bottle, including a mounting bracket. The bottom of the mounting bracket is threadedly connected to an outer bottle and an inner bottle, with the inner bottle placed inside the cavity of the outer bottle. A nozzle device is mounted on the mounting bracket, comprising a pressing cap, a valve stem, and a sealing cap. The pressing cap is mounted on the valve stem, and the sealing cap is fitted onto the valve stem. To remove the inner bottle, the outer bottle is unscrewed from the mounting bracket, and then the inner bottle is unscrewed from the mounting bracket for replacement. While this technical solution also allows for inner bottle replacement, its nozzle device and mounting bracket setup are relatively complex. Replacing the inner bottle requires disassembling and reinstalling the nozzle device, which is cumbersome and increases the burden on consumers. Summary of the Invention

By connecting the extrusion component with the cavity of the outer shell component, the replacement steps are simplified, the operation is simple and reliable, and the practicality of the packaging container is effectively improved, enhancing the user experience.
[0006] To solve the above-mentioned technical problems, the present invention provides a technical solution as follows: a packaging container for daily chemical products, comprising an axially connected extrusion assembly and a shell assembly; the extrusion assembly includes a support frame with a frame structure, a connecting channel at the bottom of the support frame, a variable volume airbag in the inner cavity of the support frame, and a one-way air outlet valve at the bottom of the airbag facing the connecting channel; the shell assembly includes a shell with a hollow cavity structure, a connector at the top of the shell that connects to the extrusion assembly, and a detachable end cap at the bottom, a replacement bottle can be installed in the shell cavity, and the replacement bottle can contain a fluid; wherein, the one-way air outlet valve communicates with the shell cavity through the connector to form a sealed gas channel, and the compressed gas from the airbag enters the shell cavity through the gas channel, driving the fluid in the replacement bottle to move toward the bottom of the shell.
[0007] Furthermore, the inner cavity of the support frame is provided with two clamping plates that can move in opposite directions on both sides along the axial direction. The airbag is located between the two clamping plates and squeezes the clamping plates in opposite directions. The compressed gas in the airbag enters the replacement bottle and drives the fluid inside the replacement bottle to move towards the bottom end of the shell.
[0008] Furthermore, the support frame includes a first support end and a second support end arranged in parallel. The first support end and the second support end are connected by two symmetrically arranged support walls. The interval between the two support walls forms a compression port corresponding to the clamping plate, and a force is applied to the clamping plate through the compression port.
[0009] Furthermore, the clamping plate is vertically slidably disposed between the first support end and the second support end.
[0010] Furthermore, the clamping plate has guide posts extending axially at both ends, and the first support end and the second support end are provided with sliding grooves that slide in cooperation with the guide posts.
[0011] Furthermore, one end of each of the two clamping plates is simultaneously hinged to the first support end or the second support end. When the clamping plates are pressed against each other, the other ends of the clamping plates move towards each other, compressing the airbag.
[0012] Furthermore, each of the two clamping plates has a hinge shaft at one end, and the first support end or the second support end has an ear corresponding to the hinge shaft. The two clamping plates are simultaneously hinged to the first support end or the second support end through the hinge shaft and the ear.
[0013] Furthermore, one end of each of the two clamping plates, which are in the same direction, is hinged to the first support end, and the other end is slidably connected to the second support end.
[0014] Furthermore, the two clamping plates are provided with a hinge shaft at one end facing the first support end, the first support end is provided with an ear that is hinged to the hinge shaft, and the two clamping plates are provided with a guide post at one end facing the second support end, the second support end is provided with a sliding groove that slides with the guide post.
[0015] Furthermore, one end of each of the two clamping plates, which are in the same direction, is slidably connected to the first support end, and the other end is hinged to the second support end.
[0016] Furthermore, the two clamping plates are provided with guide posts at one end facing the first support end, the first support end is provided with a sliding groove that slides with the guide posts, the clamping plate is provided with a hinge shaft at one end facing the second support end, and the second support end is provided with an ear that is hinged to the hinge shaft.
[0017] Furthermore, the support frame includes a base with a connecting channel and an upper shell connected above the base. The top of the airbag is provided with a pressure plate. Pressing the pressure plate along the axial direction of the support frame causes the compressed gas in the airbag to enter the replacement bottle, driving the fluid inside the replacement bottle to move toward the bottom end of the shell.
[0018] Furthermore, the connector is a connecting post protruding from the top of the housing, and the connecting post is threadedly connected to the connecting channel to form the gas channel.
[0019] Furthermore, the base is provided with a stop wall facing the pressure plate, and the stop wall is used to limit the axial movement of the pressure plate.
[0020] This utility model also provides a replacement bottle for use with the packaging container described in any of the above claims. The replacement bottle includes a bottle body with a hollow cavity structure, a bottle mouth at one end of the bottle body, and a slidable sealing film on the inner wall of the other end of the bottle body.
[0021] Furthermore, the sealing diaphragm is made of elastic rubber, and its edge is press-fitted with the inner wall of the bottle to form a sliding seal.
[0022] Furthermore, the bottle mouth is fitted with a sealing cap for sealing the bottle mouth, the outer wall of the bottle mouth is provided with a second external thread, the sealing cap is provided with a second internal thread that mates with the second external thread, and the sealing cap is threadedly connected to the bottle mouth.
[0023] Furthermore, the bottle body is made of a biodegradable material.
[0024] This utility model also provides a daily chemical product, including the above-mentioned packaging container and the above-mentioned replacement bottle. The replacement bottle has a fluid inside its body cavity. The replacement bottle is detachably installed in the housing cavity. One end of the replacement bottle facing the extrusion assembly is provided with an annular sealing ring that seals with the inner wall of the cavity, and the other end is the bottle opening. The compressed gas from the airbag enters the bottle body cavity, which can drive the sealing diaphragm to move toward the bottle opening, extruding the fluid inside the replacement bottle from the bottle opening.
[0025] Furthermore, the inner wall of the shell cavity is provided with a first internal thread, and the outer wall of the bottle body is provided with a first external thread that mates with the first internal thread, and the bottle body is threadedly connected to the inner wall of the shell cavity.
[0026] The packaging container provided by this utility model, compared with the prior art, is axially combined with the extrusion component and the outer shell component, and the extrusion component is connected to the shell cavity. The bottom end is provided with a detachable end cap, and the replacement bottle can be placed into the shell cavity from the bottom end of the shell. During the replacement of the replacement bottle, there is no need to disassemble the extrusion component, which effectively simplifies the replacement steps, makes the operation simple, and improves the practicality of the packaging container. The reusable nature of the extrusion component and the outer shell component also improves the environmental protection and economy of the product. Through the axial cooperation between the variable volume airbag and the replacement bottle, the deformation of the airbag can compress gas to drive the fluid inside the replacement bottle to flow out from the far end. It is relatively convenient to use one hand to apply force to the airbag and squeeze the airbag to directly discharge the material. The operation is convenient. The sealed gas channel formed by the one-way air outlet valve and the connector can stably realize the transmission of compressed gas from the airbag to the inside of the cavity. There is no need to press repeatedly to expel air during the first use. In particular, the symmetrically arranged clamps on both sides of the support frame along the axial direction, and the airbag between the clamps, allow for convenient application of force to the clamps from both sides of the support frame using two fingers to squeeze the airbag. The sealed gas channel formed by the one-way exhaust valve and connecting hole ensures stable transmission of compressed gas from the airbag to the interior of the shell cavity. Compared to existing technologies, the daily chemical product provided by this invention, through a packaging container equipped with a squeezing component and a replacement bottle sealed to the inner wall of the shell cavity, forms a sealed gas channel. This allows compressed gas from the airbag to enter the shell cavity, effectively driving the displacement of the sealing diaphragm of the replacement bottle and squeezing out the contents. The detachable connection between the replacement bottle and the shell allows the bottle containing the fluid to be used as a replacement, facilitating easy replacement, improving the product's environmental friendliness, and reducing overall product costs. Furthermore, the replacement bottle body is made of biodegradable material, further enhancing the product's environmental friendliness. Attached Figure Description

[0043] To make the objectives, technical solutions, and advantages of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.
[0044] It should be noted that if the embodiments of this application involve directional indicators (such as up, down, left, right, front, back, top, bottom, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.
[0045] like Figure 1 , 2As shown in Figures 11 and 12, one embodiment of this utility model relates to a packaging container, including an axially connected compression assembly 10 and a shell assembly 20. The compression assembly 10 includes a support frame 11 with a frame structure. The bottom of the support frame 11 is provided with connecting channels 115 and 119. The inner cavity of the support frame 11 is provided with a variable volume airbag 13, the bottom of which faces the connecting channel 115. The 119 is provided with a one-way air outlet valve 131. The shell assembly 20 includes a shell 21 with a hollow cavity structure. The top of the shell 21 is provided with a connecting channel 115 and 119. The connecting parts of channels 115 and 119 are provided with a detachable end cap 22 at the bottom. A replacement bottle 30 can be installed in the cavity of the housing 21, and the replacement bottle 30 can contain fluid. The one-way gas valve 131 is connected to the cavity of the housing 21 through the connecting parts to form a sealed gas channel 120. The driving airbag 13 compresses gas and enters the cavity of the housing 21 through the gas channel 120. The air pressure drives the fluid in the replacement bottle 30 to move towards the far end, that is, the bottom end of the housing 21, so that the fluid can flow out from the far end of the housing assembly 20.
[0046] like Figure 1 , 2As shown in Figure 11, one embodiment of this utility model relates to a packaging container, including an axially connected extrusion assembly 10 and a shell assembly 20. Preferably, the extrusion assembly 10 and the shell assembly 20 are coaxially arranged. The extrusion assembly 10 includes a support frame 11 with a frame structure. Two clamping plates 12 that can move in opposite directions are provided on both sides of the axial direction inside the support frame 11. Preferably, the two clamping plates 12 are symmetrically arranged on both sides of the axial direction of the support frame 11. A variable volume airbag 13 is provided between the two clamping plates 12. The airbag 13 is provided with a one-way air inlet valve (not shown in the figure). The one-way air inlet valve is provided with a reset structure. When the air pressure inside the airbag 13 is less than the external air pressure, the air inlet channel is opened. When the air pressure inside the airbag 13 is greater than or equal to the external air pressure, the airbag is reset and closed. A one-way air outlet valve 131 is provided at the bottom. The one-way air outlet valve 131 is provided with a pressure trigger structure, which can open the channel under gas pressure. The airbag 13 is made of a flexible, elastic material, allowing its internal volume to change through compression and deformation. To increase the lifespan of the airbag 13, it can be designed with a corrugated shape. Preferably, the one-way inlet valve is located at the top of the airbag 13, corresponding to the one-way outlet valve 131. However, depending on actual needs, the one-way inlet valve can be located in other parts of the airbag 13 without affecting its functionality. The one-way inlet valve with a reset structure and the one-way outlet valve 131 with a pressure-triggered structure on the airbag 13 are common components in the prior art, and their structures will not be described in detail here. The outer shell assembly 20 includes a shell 21 with a hollow cavity structure. The cavity of the shell 21 is used to accommodate a replacement device, which is a replacement bottle 30 containing a daily chemical fluid. The shell 21 has a connecting wall 23 extending inward toward the top of the extrusion assembly 10. The connector is a connecting hole 231 that penetrates the connecting wall 23 and communicates with the cavity of the shell 21. The bottom end of the shell 21 is provided with a detachable sealing end cap 22. By separating the end cap 22 from the shell 21, the replacement device can be placed into the cavity of the shell 21 through the opening at the bottom end of the shell 21. The sealing end cap 22 can be connected to the shell 21 by a threaded connection or by a snap-fit connection. Preferably, the axial projection of the sealing end cap 22 is consistent with the axial projection shape of the shell 21, so that the sealing end cap 22 and the shell 21 can form a columnar structure with a flush outer surface after being connected.By combining the extrusion assembly 10 with the outer shell assembly 20, the extrusion assembly 10 is connected to the cavity of the shell 21. The replacement unit can be placed into the cavity of the shell 21 from the bottom end, so that the extrusion assembly 10 does not need to be disassembled during the replacement of the replacement unit, which effectively simplifies the replacement steps, makes the operation simple, and improves the practicality of the packaging container. The clamping plates 12 arranged on both sides along the axial direction in the support frame 11, and the air bladder 13 between the clamping plates 12, make it easy to operate with one hand. By squeezing the air bladder 13 from the side with two fingers, it is easier to apply force to the clamping plates 12 and squeeze the air bladder to directly discharge the material. The operation is convenient and there is no need to press repeatedly to expel air when using it for the first time. The sealed gas channel 120 formed by the one-way air outlet valve 131 and the connecting hole 231 can stably realize the transmission of compressed gas from the air bladder 13 to the cavity.
[0047] The compression assembly 10 and the outer shell assembly 20 are detachably connected. After the compression assembly 10 and the outer shell assembly 20 are assembled, the one-way exhaust valve 131 communicates with the cavity of the shell 21 through the connecting hole 231 to form a sealed gas channel 120. The airbag 13 is compressed by the opposing compression clamps 12, and the airbag 13 deforms, reducing its volume and thus compressing the gas inside the airbag 13. The gas then enters the replacement bottle 30 inside the cavity of the shell 21 through the one-way exhaust valve 131, driving the fluid inside the replacement bottle 30 to move towards the bottom of the shell 21. When the force on the clamps 12 is released, the airbag 13 can recover under the rebound force. At this time, external air can enter the interior of the airbag 13 through the one-way intake valve. In one example, the support frame 11 includes a first support end 111 and a second support end 112 arranged parallel to each other vertically. The first support end 111 and the second support end 112 are connected by two symmetrically arranged support walls 113. The interval between the two support walls 113 forms two compression ports 114 corresponding to the two clamping plates 12, so that force can be directly applied to the clamping plates 12 through the compression ports 114. Through the arrangement of the compression ports 114 and the clamping plates 12, force can be applied to the clamping plates 12 laterally, that is, force can be applied to the clamping plates 12 in a direction perpendicular to the axial direction of the compression assembly 10. In actual use, force can be easily applied to the clamping plates 12 using two fingers of one hand, driving the airbag 13 to deform and compress the gas for discharge. Preferably, the second support end 112 located near the outer shell assembly 20 is provided with a connecting channel 115. The connecting channel 115 is sealed and inserted into the connecting hole 231 at the top of the shell 21. The one-way vent valve 131 is sealed and sleeved within the connecting channel 115, allowing gas in the airbag 13 to be transmitted into the cavity of the shell 21 through the connecting channel 115 and the connecting hole 231. The connection channel 115 helps to increase the stability of the connection between the extrusion assembly 10 and the outer shell assembly 20, thereby increasing the durability of the packaging container.
[0048] like Figure 3-4As shown, one embodiment of this utility model relates to a packaging container. The support frame 11 includes a first support end 111 and a second support end 112 arranged in parallel, and two clamping plates 12 symmetrically arranged between them. The clamping plates 12 are vertically slidably disposed between the first support end 111 and the second support end 112. Guide posts 122 extend axially from both ends of the clamping plates 12. The first support end 111 and the second support end 112 are provided with sliding grooves 116 that slide with the guide posts 122. When a force is applied to the clamping plates 12 on both sides, the guide posts 122 can slide along the sliding grooves 116, thereby realizing the opposite displacement of the clamping plates 12 and compressing the airbag 13 located between the clamping plates 12. In one example, the edges of the first support end 111 and the second support end 112 are provided with vertical walls 118 extending towards each other. When the clamping plates 12 are reset under the elastic force of the airbag 13, the vertical walls 118 can stop and limit the edges of the clamping plates 12, preventing the clamping plates 12 from slipping out of the support frame 11. Preferably, the two clamping plates 12 extend toward each other and are provided with limiting parts 123. The limiting parts 123 can block each other in the direction in which the clamping plates 12 move toward each other, preventing the clamping plates 12 from over-compressing the airbag 13 and causing a reduction in the service life of the airbag 13. The limiting parts 123 can also effectively control the amount of compression deformation of the airbag 13 and realize the quantitative output of compressed gas from the airbag 13.
[0049] like Figure 5-7 As shown, one embodiment of this utility model relates to a packaging container. The support frame 11 includes a first support end 111 and a second support end 112 arranged in parallel, and two clamping plates 12 symmetrically arranged between them. The clamping plates 12 are parallel when not subjected to external force. Corresponding ends of the two clamping plates 12, i.e., ends in the same direction, are simultaneously hinged to either the first support end 111 or the second support end 112. When the clamping plates 12 are pressed towards each other, the other ends of the clamping plates 12 move towards each other, compressing the air bladder 13. That is, the non-hinged ends of the clamping plates 12 can rotate around the hinge axis 121, compressing the air bladder 13, thereby expelling compressed gas from the air bladder 13 into the cavity of the shell 21. Figure 7 As shown, in one example, the ear portion 117 is disposed on the vertical wall 118 of the second support end 112. When the clamping plate 12 rotates around the hinge axis 121, the rotation amplitude of the clamping plate 12 can be limited by the abutment between the end of the clamping plate 12 and the vertical wall 118, thereby controlling the amount of compression deformation of the airbag 13 and realizing the quantitative output of compressed gas from the airbag 13. Preferably, the non-hinged ends of the two clamping plates 12 are provided with limiting portions 123 extending towards each other. The limiting portions 123 of the two clamping plates 12 can block each other in the direction of the clamping plates 12 moving towards each other, preventing the clamping plates 12 from over-compressing the airbag 13 and reducing the service life of the airbag 13. The limiting portions 123 can also effectively control the amount of compression deformation of the airbag 13 and realize the quantitative output of compressed gas from the airbag 13.
[0050] like Figure 4 , 7 As shown in Figure 8, one embodiment of this utility model relates to a packaging container. The support frame 11 includes a first support end 111 and a second support end 112 arranged in parallel, and two clamping plates 12 symmetrically arranged between them. The clamping plates 12 are parallel when not subjected to external force. One end of each clamping plate 12, facing the same direction, is hinged to the first support end 111, and the other end is slidably connected to the second support end 112. In one example, the ends of the two clamping plates 12 facing the first support end 111 are provided with a hinge shaft 121. The first support end 111 is provided with an ear 117 hinged to the hinge shaft 121. The ends of the two clamping plates 12 facing the second support end 112 are provided with a guide post 122, and the second support end 112 is provided with a groove 116 that slidably engages with the guide post 122. The arrangement of hinged ends and slidably connected ends between the clamping plates 12 and the support ends increases the stability and smoothness of the clamping plates 12 when they move towards each other.
[0051] like Figure 4 , 7 As shown in Figure 8, one embodiment of this utility model relates to a packaging container. The support frame 11 includes a first support end 111 and a second support end 112 arranged in parallel, and two clamping plates 12 symmetrically arranged between them. The clamping plates 12 are parallel when not subjected to external force. One end of each clamping plate 12, facing the same direction, is slidably connected to the first support end 111, and the other end is hinged to the second support end 112. In one example, the end of each clamping plate 12 facing the first support end 111 is provided with a guide post 122. The first support end 111 is provided with a groove 116 that slidably engages with the guide post 122. The end of each clamping plate 12 facing the second support end 112 is provided with a hinge shaft 121, and the second support end 112 is provided with an ear 117 hinged to the hinge shaft 121. By hinged at one end and slidably connected at the other end between the clamping plates 12 and the support end, the stability and smoothness of the clamping plates 12 when moving towards each other are improved.
[0052] like Figure 12-14As shown, one embodiment of this utility model relates to a packaging container, including an axially connected extrusion assembly 10 and a shell assembly 20. Preferably, the extrusion assembly 10 and the shell assembly 20 are coaxially arranged. The extrusion assembly 10 includes a support frame 11 with a frame structure. The support frame 11 includes a base 1102 with a connecting channel 119 and an upper shell 1101 connected above the base 1102. The base 1102 and the upper shell 1101 are detachably fixedly connected. A variable volume airbag 13 is provided in the cavity of the support frame 11. The airbag 13 is provided with a one-way air outlet valve 131 facing the connecting channel 119. A pressure plate 14 is provided on the top of the airbag 13. A pressing port 1104 corresponding to the axial direction of the pressure plate is provided on the top of the support frame 11. By pressing the pressure plate 14 along the axial direction of the support frame 11 through the pressing port 1104, the airbag 13 is driven to deform and compress gas, which enters the cavity of the shell 21 through the gas channel 120 and then enters the replacement bottle 30. The air pressure drives the fluid inside the replacement bottle 30 to move towards the far end, i.e., the bottom end of the shell 21. In one example, the housing 21 extends inward toward the top of the extrusion assembly 10 with a connecting wall 23. A connecting post 232 protrudes from the connecting wall 23 and communicates with the cavity of the housing 21. The connecting post 232 has an external thread, and the connecting channel 119 has an internal thread that mates with the external thread of the connecting post 232. The connecting post 232 and the connecting channel 119 are threadedly sealed together, forming a gas channel 120 for the airbag 13 to transmit gas to the cavity of the housing 21. The threaded connection between the connecting post 232 and the connecting channel 119 also allows the extrusion assembly 10 and the housing assembly 20 to form a detachable connection, facilitating later maintenance of the packaging container. Preferably, the base 1102 has a stop wall 1103 facing the pressure plate 14. The base 1102 is fixed to the upper housing 1101 by the stop wall 1103. When the pressure plate 14 is pressed to drive the airbag to deform, the stop wall 1103 can limit the pressure plate 14 in the pressing direction, thereby controlling the deformation of the airbag 13 and achieving a quantitative output of compressed gas from the airbag 13.
[0053] The packaging container provided by this utility model is axially combined with the extrusion assembly 10 and the outer shell assembly 20, and the extrusion assembly 10 is connected to the cavity of the shell 21. When replacing the replacement container, the replacement container can be placed into the cavity of the shell 21 from the bottom end without disassembling the extrusion assembly 10, which effectively simplifies the replacement process, makes the operation simple, and improves the practicality of the packaging container. The reusability of the extrusion assembly 10 and the outer shell assembly 20 effectively improves the environmental friendliness and economy of the product. The variable volume airbag 13 and the replacement bottle 30 are axially matched. The deformation of the airbag 13 can compress gas to drive the fluid inside the replacement bottle 30 to flow out from the far end. It is convenient to apply force to the airbag 13 with one hand, which is easy to operate. The sealed gas channel 120 formed by the one-way air outlet valve 131 and the connector can stably realize the transmission of compressed gas from the airbag 13 to the cavity of the shell 21. It is not necessary to press repeatedly to expel air during the first use. In particular, the clamping plates 12 symmetrically arranged on both sides of the support frame 11 along the axial direction, and the airbag 13 between the clamping plates 12, allow for convenient application of force to the clamping plates 12 from both sides of the support frame 11 with two fingers of one hand, compressing the airbag 13. This is easy to operate. The sealed gas channel 120 formed by the one-way exhaust valve 131 and the connecting hole 231 can stably achieve the transmission of compressed gas from the airbag 13 to the cavity of the housing 21. Furthermore, the pressure plate 14 set on the top of the airbag 13 allows for convenient application of axial pressure to the airbag 13 with one hand. This is also easy to operate. The sealed gas channel 120 formed by the one-way exhaust valve 131 and the connecting column 232 can stably achieve the transmission of compressed gas from the deformed airbag 13 to the cavity of the housing 21.
[0054] like Figure 9 , 11 As shown in Figures 12 and 14, this embodiment of the present invention also provides a replacement bottle for use in conjunction with the aforementioned packaging container. The replacement bottle 30 includes a bottle body 32 with a hollow cavity structure, a bottle mouth 33 at one end of the bottle body 32, and a slidable sealing diaphragm 31 on the inner wall of the other end of the bottle body 32. Preferably, the sealing diaphragm 31 is made of elastic rubber, and its edge is press-fitted with the inner wall of the bottle body 32 to form a sliding seal.
[0055] To prevent external air or pollutants from entering the replacement bottle 30 through the bottle opening 33 and contaminating its contents, a sealing cap 34 is fitted over the bottle opening 33 to seal it. The outer wall of the bottle opening 33 has a second external thread 331, and the sealing cap 34 has a second internal thread 341 that mates with the second external thread 331. The sealing cap 34 is threadedly connected to the bottle opening 33. To further enhance the product's environmental performance, the replacement bottle 30 is preferably made of biodegradable materials, such as PHA (polyhydroxyalkanoate), paper, etc., to make the bottle body 32.
[0056] like Figure 9-11 As shown, one embodiment of this utility model relates to a daily chemical product, including any of the above-mentioned packaging containers, and a detachable replacement bottle 30 disposed within the housing 21. The replacement bottle 30 is generally used to contain liquids, such as purified water, serums, etc., and can also contain emulsion-like fluids, such as foundation, eye cream, etc., or other cream-like fluids. As a replacement container, the replacement bottle 30 can be easily and quickly replaced after the fluid inside is used up, while retaining the packaging container for reuse, which is beneficial for resource conservation, improving the environmental friendliness of the product, and reducing the overall cost of the product. The replacement bottle 30 has a bottle body 32, one end of which has a bottle opening 33, and the other end has a sliding sealing membrane 31. The sealing membrane 31 seals the end of the bottle body 32 away from the bottle opening 33, so that the fluid contained in the bottle body 32 can only be discharged from the bottle opening 33. The end of the bottle body 32 facing the extrusion assembly 10 is provided with an annular sealing ring 24 that seals against the inner wall of the cavity of the housing 21. This prevents gas from the airbag 13 from entering the cavity of the housing 21 and leaking out through the gap between the bottle body 32 and the inner wall of the cavity of the housing 21. Preferably, the sealing diaphragm 31 is made of elastic rubber, and its edge is press-fitted with the inner wall of the bottle body 32 to form a sliding seal. When the clamping plate 12 is pressed against each other, the airbag 13 deforms, and compressed gas enters the cavity of the housing 21. Then, under the drive of gas pressure, the sealing diaphragm 31 moves along the inner wall of the bottle body 32 toward the bottle opening 33, squeezing the fluid in the replacement bottle 30 out of the bottle opening 33. The replacement bottle 30, as a replacement device, forms a detachable fixed connection with the outer shell assembly 20. In one example, the inner wall of the cavity is provided with a first internal thread 211, and the outer wall of the bottle body 32 is provided with a first external thread 321 that mates with the first internal thread 211. The end of the bottle body 32 facing the extrusion assembly 10 is threadedly connected to the inner wall of the housing 21.
[0057] The daily chemical products provided by this utility model, compared with the prior art, form a sealed gas channel through a packaging container equipped with a compression component and a replacement bottle sealed to the inner wall of the shell cavity. This allows compressed gas from the airbag to enter the shell cavity, effectively driving the displacement of the sealing diaphragm of the replacement bottle and squeezing out the contents of the replacement bottle. The detachable connection between the replacement bottle and the shell allows the replacement bottle containing the fluid to be used as a replacement, making it more convenient to replace, improving the environmental friendliness of the product, and helping to reduce the overall cost of the product. In particular, the bottle body of the replacement bottle is made of a biodegradable material, which further enhances the environmental friendliness of the product.
[0058] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications and improvements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the claims.
