Description

Technical Field

[0001] The present invention relates to the technical field of packaging bottles, and more particularly to a replaceable multi-tube push-to-pack packaging bottle and a method for replacing the multi-tube push-to-pack packaging bottle. Background Art

[0002] A push-type bottle has a pump mounted on its cap that pumps the liquid inside, making it easy to access. To prevent accidental contact during storage and to create a more integrated outer tube, a packaging container is often placed outside the push-type bottle to package it.

[0003] There are usually two forms of current pump bottle packaging. The first one is that the container of the packaging bottle is usually set up with a two-end structure, the lower side of which is the container body, the pump bottle is installed in the container body, and the bottle cap, pump and cover of the pump bottle are exposed at the outer periphery of the upper end of the container. In addition, the container has a lid, which can be used to cover the part of the pump bottle exposed at the upper end of the container body; when it needs to be used, the lid can be removed, and the pumping part at the upper end of the pump bottle can be protected by the lid to avoid accidental touch. Moreover, the shape and contour of the lid can be set to be consistent with the container body, so that the packaging bottle has a more consistent integrity.

[0004] Another type of packaging bottle adopts a telescopic structure, that is, the container of the packaging bottle adopts a lipstick tube structure, and the pressing bottle is placed in the container. By rotating and adjusting, the pressing bottle can be driven to achieve up and down telescopic adjustment, with a certain up and down lifting stroke. At the bottom of the stroke, such as Figure 10 As shown, the push bottle is completely retracted into the container, realizing the protection of the push bottle against accidental touch; at the uppermost position of the stroke, as shown Figure 11 As shown, the upper end portion of the push cover of the push bottle is exposed to the outside, and the push cover can be pressed, thereby making it convenient to use.

[0005] Multi-tube push-button packaging bottles combine multiple push-button bottles within a single container, making it easy to carry multiple liquids and providing convenient use. However, with multi-tube packaging bottles, the push-button tubes may need to be removed and replaced, for example, if one liquid runs out prematurely or if a different liquid type needs to be replaced. However, replacing these current multi-tube packaging bottles is quite inconvenient, impacting the user experience.

[0006] Therefore, a new solution needs to be proposed to solve this problem. Summary of the Invention

[0018] The present invention is further configured such that the outline of the bottle body 1 of the pressing bottle 1 is smaller than the mounting hole 1, and a positioning ring is formed on the inner periphery of the mounting hole 1, and the positioning ring is used to press upward against the lower end surface of the bottle cap 1 to limit the position; the bottle cap 1 and the mounting ring 1 are clamped with each other.

[0019] The present invention is further configured such that a card block is fixed on the inner circumference of the mounting hole 1, the card block extends along the circumference of the mounting hole 1, a card groove is formed on the outer circumference of the bottle cap 1, the card groove and the card block are mutually engaged and adapted, and extend along the circumference of the bottle cap 1, a notch 1 is formed on the lower side of the card groove for the card block to extend into; a concave and convex structure that adapts to each other is formed between the card block and the card groove.

[0027] The extension sleeve and container are directly connected by a threaded connection structure. During the disassembly process, the extension sleeve can be raised and lowered relative to the container. The disassembly of the extension sleeve pushes the push cap on the upper side of the push bottle upward, thereby moving the push cap upward, making it easier to remove the push cap. In addition, the threaded structure converts the disassembly spiral rotation into axial displacement, which saves effort and facilitates the removal of the push cap of the push bottle.

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] This embodiment discloses a replaceable multi-tube press packaging bottle, such as Figure 1-3 As shown, it includes several groups of push bottles 2 and containers 1. The groups of push bottles 2 are packaged together by the container 1, which is convenient for carrying and use.

[0042] The push bottle 2 includes a bottle body, a bottle cap, and a push cover 3. The bottle cap is equipped with a push pump, and the push cover 3 is mounted on the push pump. By pressing the push cover 3, the push pump is driven to perform a pumping action, thereby pumping out the contents of the bottle body. The specific structure of the push pump is prior art and will not be described in detail here.

[0043] The container 1 is hollow, forming a hollow chamber within the container 1 that accommodates the body of the push bottle 2. The container 1 has an upper end cap 13 on its upper side, with mounting holes 14 defined therein. The number of mounting holes 14 corresponds to the number of push bottles 21. Push bottles 2 can be mounted through the corresponding mounting holes 14, allowing the caps and pumps of the push bottles 2 to be exposed at the top of the container 1. The push cap 3 of the push bottle 2 is located above the upper end cap 13, allowing for pumping.

[0044] The packaging bottle also includes a cylindrical extension sleeve 4, which is removably mounted above the container 1. The outer contour of the extension sleeve 4 matches the contour of the container 1, forming a relatively smooth, integrated structure when installed above the container 1. This extension sleeve 4 encloses the bottle caps and push-on caps 3 of each set of push-on bottles 2 extending above the container 1, thereby protecting the pumping mechanism of each push-on bottle 2 and preventing accidental activation. Furthermore, once installed, the extension sleeve 4 forms a uniform and consistent contour with the container 1 of the packaging bottle.

[0045] In the packaging bottle, the number of pressing bottles 2 can be a multi-tube structure, for example, a double-tube, triple-tube structure, or multiple tubes can be provided according to the needs. Generally speaking, the number of pressing bottles 2 is more common with a double-tube structure, that is, two bottles are installed in the packaging bottle, which can store two different liquid materials, such as Figure 3 The structure shown.

[0046] like Figure 3 、 4As shown in FIG5 , each pressing cover 3 of each pressing bottle 2 can adopt an integrated structure, and each pressing cover 3 can realize the pressing action synchronously, thereby making the liquid material in each pressing bottle 2 be sprayed out at the same time for easy use. Figure 4 As shown, multiple liquid-conducting channels 33 are formed in the pressing cover 3, and each liquid-conducting channel 33 corresponds to each pressing pump. A port 331 is formed at the first end of each liquid-conducting channel 33, and each port 331 corresponds to a respective pressing pump. After the pressing cover 3 is installed, the port 331 and the pressing pump are installed and connected to each other. The second end of the liquid-conducting channel 33 is a liquid outlet 332 for spraying liquid. Each liquid outlet 332 extends to the periphery of the pressing cover 3 and converges into one location, allowing each group of liquids to be sprayed simultaneously into one location, allowing two liquids to be mixed simultaneously for user convenience.

[0047] like Figure 3 、 4 As shown, to facilitate installation of the push cover 3, a foolproof block 132 can be fixedly connected to the upper end cover 13, and a foolproof block 2 34 can be fixed to the inner bottom surface of the push bottle 2. The foolproof block 132 and the foolproof block 2 34 guide and limit each other, and a mutually adaptable slot structure can be set between the two. The two can only align with each other in one position. After the alignment and installation, the various interfaces 331 on the lower side of the push cover 3 and the various press pumps are precisely aligned with each other, thereby facilitating installation of the push cover 3 and ensuring that each interface 331 is aligned with each press pump 1 214.

[0048] like Figure 5 As shown, the extension sleeve 4 can be raised and lowered relative to the container 1 during the disassembly process. Through the disassembly action of the extension sleeve 4, the push cover 3 on the upper side of the push bottle 2 can be pushed upward, thereby moving the push cover 3 upward, making the push cover 3 easy to disassemble.

[0049] A limiting ring 1 31 protruding outward is formed on the outer periphery of the pressing cover 3 , and a stepped surface 1 32 is formed on the lower side of the limiting ring 1 , with the stepped surface 1 32 facing the container 1 .

[0050] A protruding stop ring 41 is formed on the inner circumference of the extension sleeve 4. A stepped surface 42 is formed above the stop ring 41, with the stepped surface 32 facing the stepped surface 42. During removal, the extension sleeve 4 can move up and down relative to the container 1. When the extension sleeve 4 moves upward, the stepped surface 42 abuts against the stepped surface 32, exerting a force on the push-on cap 3 away from the bottle, disengaging the push-on cap 3 from the pump and enabling removal.

[0051] Specifically, if Figure 6 、 7As shown, a threaded connection structure can be used between the extension sleeve 4 and the container 1. An internal thread 43 can be formed on the inner periphery of the lower end of the extension sleeve 4, and an external thread 121 can be formed on the outer periphery of the upper end of the container 1. The internal thread 43 and the external thread 121 are adapted to each other, so that the extension sleeve 4 can be threadedly mounted on the upper end of the container 1. By rotating the extension sleeve 4 with threads, the extension sleeve 4 can be raised and lowered relative to the container 1, thereby allowing the extension sleeve 4 to be removed from the upper end of the container 1. During the lifting and lowering stroke of the disassembly, the stepped surface 2 42 of the extension sleeve 4 can press against the stepped surface 1 32 of the pressing cover 3, thereby converting the spiral motion of the extension sleeve 4 into an axial motion, forming a relatively labor-saving disassembly structure, thereby facilitating the disassembly and assembly of the pressing cover 3.

[0052] Each group of push bottles 2 can adopt a quick-release structure with the container 1. The push bottles 2 can be installed on the upper end cover 13 of the container 1, and then the installed bottles can be directly pulled upward from the corresponding installation holes 14. During installation, the push bottles 2 can be inserted into the corresponding installation holes 14 from top to bottom, which is convenient for disassembly and assembly of the installed bottles. The push bottles 2 can be replaced by disassembly and assembly, which is convenient for users to replace and use, and also allows the container 1 for packaging bottles to be recycled. In addition, in each group of push bottles 2, some of the push bottles 2 can adopt a quick-release structure, while other parts of the push bottles 2 can not adopt a quick-release structure, so that only the push bottles 2 with a quick-release structure can be replaced, and only some of the push bottles 2 can be disassembled and replaced.

[0053] like Figure 5-8 The connection structure between the push-on bottles 2 and the container 1 is described in detail using two sets of push-on bottles 2 as an example. The two sets of push-on bottles 2 are push-on bottle 1 21 and push-on bottle 2 22 , respectively. Mounting holes 141 and 142 are provided on the upper end cover 13 of the container 1 for mounting the two push-on bottles 2 , respectively.

[0054] Among them, the mounting bottle 1 adopts a quick-detachable connection structure. The bottle body 211 of the pressing bottle 1 21 can be moved up and down in the mounting hole 141, and the bottle cap 213 of the pressing bottle 1 21 can be detachably connected to the mounting hole 141, thereby facilitating disassembly and assembly.

[0055] Specifically, the outline of the bottle body 1211 of the pressing bottle 121 is smaller than the mounting hole 141, so that the bottle body 1211 of the pressing bottle 121 can smoothly pass through the mounting hole 141, and can be easily disassembled and replaced at the mounting hole 141. The lower end portion of the bottle cap 1213 extends into the mounting hole 141, and the lower end surface of the bottle cap 1213 can be pressed against the positioning ring 1411 to limit the position. In addition, a clamping structure is provided between the bottle cap 1213 and the mounting ring 1. After the bottle cap 1213 and the positioning ring 1411 are pressed against each other to limit the position, the bottle cap 1213 can be rotated to clamp the bottle cap 1213 and the inner periphery of the mounting hole 141 to fix it.

[0056] Specifically, if Figure 8 As shown, a clamping block 1412 is fixed to the inner circumference of mounting hole 141. Clamping block 1412 is positioned higher than positioning ring 1411 and extends circumferentially around mounting hole 141. A clamping groove 2131 is formed on the outer circumference of bottle cap 113. Clamping groove 2131 engages with clamping block 1412 and extends circumferentially around bottle cap 113. A notch 2132 is formed below clamping groove 2131 and fits with clamping block 1412. After the bottle cap 1 213 is supported by the positioning ring 1411, the notch 1 2132 on the lower side of the slot 2131 is aligned with the clamping block 1412, and the clamping block 1412 is inserted into the slot 2131 through the notch 1 2132. By rotating the bottle cap 1 213, a relative axial rotation movement is formed between the clamping block 1412 and the slot 2131, and the clamping block 1412 can be inserted into the slot 2131 to achieve mutual engagement, thereby fixing the bottle cap 1 213 to the upper end cover 13. In addition, a mutually adapted concave and convex structure can be formed between the clamping block 1412 and the slot 2131, and after engagement, the two can be interlocked to achieve a connection and fixation between the two.

[0057] like Figure 6-8 As shown, the second push bottle 22 can be mounted and fixed to the upper end cap 13 of the container 1. The second push bottle 22 can adopt a non-quick-release structure. Generally speaking, the capacity of the second push bottle 22 is larger than that of the first push bottle 21. Therefore, during use, the liquid in the first push bottle 21 is used up first and can be replaced later; while the liquid in the second push bottle 22 is larger and does not need to be refilled.

[0058] Specifically, a second mounting hole 142 can be formed on the upper end cover 13. The second mounting hole 142 corresponds to the second push bottle 22. The body 221 of the second push bottle 22 is larger than the first mounting hole 141, so that the second push bottle 22 cannot be directly pulled out of the second mounting hole 142. The larger size of the second push bottle 22 can also store more liquid.

[0059] The second bottle mouth 222 of the second bottle body 221 is smaller than the second mounting hole 142. The second bottle mouth 222 extends upward from the second mounting hole 142 and is installed with a second bottle cap 223. The second bottle body 221 and the second bottle cap 223 respectively press against the ends of the second mounting hole 142 to fix the main body of the second pressing bottle 22 to the upper end plate.

[0060] In order to improve the installation stability between the pressing bottle 22 and the upper end plate, a snap ring 1421 can be fixed at the outer periphery of the bottle mouth 222. A snap ring 2221 protruding inward is fixed at the inner periphery of the mounting hole 142. The snap ring 1421 and the snap ring 2221 are mutually engaged and adapted. When the pressing bottle 22 is installed in the mounting hole 142, the snap ring 1421 and the snap ring 2221 can be mutually engaged to achieve upper and lower engagement limits, thereby maintaining the positional stability of the pressing bottle 22. In addition, a guide arc surface is formed at the upper side of the snap ring 1421, and a guide arc surface is also formed at the lower side of the snap ring 2221. The two guide arc surfaces press against each other to guide the interlocking action of the snap ring 1421 and the snap ring 2221, thereby allowing the two to be smoothly engaged and fixed.

[0061] In addition, a vertically extending limiting groove 2222 can be provided on the outer periphery of the second bottle mouth 222. A limiting block 1422 is fixed to the inner periphery of the second mounting hole 142, and the limiting block 1422 and the limiting groove 2222 are mutually adapted. When the second bottle mouth 222 is installed in the second mounting hole 142, the limiting block 1422 can be embedded in the limiting groove 2222, achieving circumferential limiting, limiting the movement of the second pressing bottle 22 after installation, and maintaining installation stability. Furthermore, the limiting block 1422 and the limiting groove 2222 are both wedge-shaped, with a larger upper portion and a smaller lower portion. When the limiting block 1422 is inserted from top to bottom into the limiting groove 2222, the position of the second pressing bottle 22 can be stably limited and fixed.

[0062] like Figure 1-3 As shown, the pressing bottle 2 can realize a structure that can be moved up and down in the container 1. When the pressing bottle 2 is lowered, the pressing cover 3 of the pressing bottle 2 can be retracted into the extension sleeve 4, protecting the upper end of the pressing bottle 2 to prevent accidental touch and forming a more integrated contour structure, as shown in FIG. Figure 1 When the pressing bottle 2 rises, the upper end portion of the pressing cover 3 of the pressing bottle 2 can extend out of the extension sleeve 4, thereby facilitating the pressing operation of the pressing cover 3 and making it easy to use.

[0063] The pressing bottle 2 is supported by the upper end plate, and the upward and downward movement adjustment of the pressing bottle 2 can be achieved by adjusting the upper end cover 13. Figure 6-9As shown, the upper end plate can be installed in the container 1 so as to move up and down, and has a certain movable stroke up and down. The bottle body and the push cover 3 can be moved up and down by adjusting the upper end plate. When the upper end plate is at the uppermost end of the movable stroke, the liquid outlet 332 on the outer periphery of the push cover 3 extends to the outside of the extension sleeve 4, and during the pressing process of the push cover 3, the liquid outlet 332 is always located outside the extension sleeve 4, so that the liquid material can be sprayed out smoothly for use. When the upper end plate is at the lowermost end of the movable stroke, the push cover 3 is completely retracted into the extension sleeve 4, and in this state, the step surface 1 32 and the step surface 2 42 between the extension sleeve 4 and the push cover 3 are pressed against each other, realizing the pressing limit of the push cover 3, and can further limit the downward pressing state of the push cover 3 to avoid accidental extrusion and pollution.

[0064] like Figure 6 、 7 As shown in Figures 9 and 9, the container 1 includes a lower shell 11, an upper shell 12 and a lifting sleeve 131. The upper shell 12 and the lower shell 11 are both cylindrical structures, wherein the upper shell 12 is through-through from top to bottom, and the bottom end of the lower shell 11 is closed. A connecting section 111 with a slightly smaller outer circumference is formed at the upper end of the lower shell 11; the upper shell 12 is sleeved on the outer circumference of the connecting section 111 to form a mutually coaxial rotation connection. A connected chamber is formed between the upper shell 12 and the lower shell 11. The lifting sleeve 131 is installed in the chamber to form a mutually sleeved structure with the lower shell 11. The upper end plate is fixedly connected to the upper end of the lifting sleeve 131, so that the upper end plate and the lifting sleeve 131 maintain synchronous lifting movements.

[0065] A protruding connecting ring 112 is machined on the outer periphery of the connecting section 111 at the upper end of the lower shell 11; a protruding connecting ring 2 122 is formed on the inner periphery of the extension sleeve 4. Connecting rings 112 and 122 press against each other upward and downward, limiting axial displacement and forming a rotating connection. Because the upper shell 12 is located at the upper end of the container 1, the external threads 121 on the outer periphery of the upper end of the container 1 are machined on the upper shell 12.

[0066] The lifting sleeve 131 forms a spiral lifting connection structure with the lower shell 11 and forms an up-and-down sliding connection structure with the upper shell 12. During the relative rotation adjustment process of the lower shell 11 and the upper shell 12, the lifting sleeve 131 and the upper end plate can be driven to move up and down.

[0067] Specifically, a guide block 133 can be formed on the outer periphery of the lifting sleeve 131, and the guide block 133 is a smooth cylindrical protrusion. A spiral guide groove 113 is formed on the circumference of the connecting section 111 of the lower shell 11. The guide block 133 can be embedded in the guide groove 113, and the lifting sleeve 131 can be spirally raised and lowered relative to the lower shell 11. A notch 2 114 is provided at the upper end of the guide groove 113 to facilitate the insertion of the guide block 133. In addition, a guide groove 2 123 running up and down is formed on the inner periphery of the upper shell 12. The guide groove 2 123 and the guide block 133 are adapted to each other. The guide block 133 passes through the guide groove 113 at the connecting section 111 and is embedded in the guide groove 113. The guide block 133 is embedded in the guide groove 2 123 to form a mutually sliding guide structure. By rotating and adjusting the lower shell 11 and the upper shell 12 relative to each other, the lower shell 11 will drive the lifting sleeve 131 to move, and then the lifting sleeve 131 and the upper end plate and the pressing tube can be adjusted up and down, so that the pressing tube can be adjusted up and down relative to the container 1, and has a certain movable stroke, so that the pressing cover 3 can be raised and lowered at the upper end position of the extension tube.

[0068] This embodiment also discloses a method for replacing a replaceable multi-tube push-button packaging bottle, using the packaging bottle described in the above embodiment. When using the packaging bottle, by pressing down the push cover 3, each group of push pumps is driven to operate simultaneously, and the contents in each group of push bottles 2 are pumped and ejected simultaneously for use. The contents in each group can be collected and used at the same time, making it convenient to use and carry.

[0069] During replacement, the extension sleeve 4 can be removed from the upper end of the container 1 by rotating the thread. In the process of rotating and removing, the extension sleeve 4 will generate an upward movement to counteract the push cover 3, pushing the push cover 3 upward, and then the push cover 3 can be removed from the press pump.

[0070] Then, the push bottle 2 that needs to be replaced is removed and replaced. Generally, the push bottle 2 that needs to be replaced is a push bottle 1 21 with a smaller capacity. The push bottle 2 that needs to be replaced is removed from the upper end cover 13 of the container 1. By rotating the push bottle 1 21, the push bottle 1 21 can be removed from the mounting hole 141. Then, the push bottle 1 21 can be pulled upward from the mounting hole 141. Then, the corresponding push bottle 1 21 that needs to be replaced is placed into the container 1 and fixed to the mounting hole 141 by rotating it, thus completing the replacement of the push bottle 1 21.

[0071] Then, install the extension sleeve 4 to the upper end of the container 1, and fix the extension sleeve 4 and the upper end of the cavity to each other by rotating the thread; then reinstall the pressing cover 3 to the pressing pump to complete the replacement of the pressing bottle 2.

[0072] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, various improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
