Description

Technical Field

[0001] This utility model relates to a packaging bottle, and more particularly to a lotion bottle and a lotion pump assembly. Background Technology

[0002] In Chinese utility model patent CN217865963U, the inventors disclosed a glass vacuum packaging bottle, which includes a glass bottle, an inner cap, a middle sleeve, an inner valve bag, a pump core assembly, a valve stem, a push cap, and a cover. The inner cap is snapped onto the outside of the bottle mouth of the glass bottle, the lower part of the middle sleeve is fitted onto the outside of the inner cap, the inner valve bag is placed inside the glass bottle, and the neck of the inner valve bag is located inside the bottle mouth of the glass bottle, the lower part of the pump core assembly passes through the middle sleeve and is inserted into the inner valve bag, and a sealing gasket is provided between the contact surface of the pump core assembly and the top of the inner valve bag. The sealed structure of the inner valve bag and the pump core assembly forms a vacuum environment, the valve stem is placed inside the inner valve bag, and the bottom end of the pump core assembly is inserted into the top end of the valve stem, the push cap is placed on the top end of the pump core assembly, and the cover covers the outside of the push cap, with the lower part of the cover fitted onto the upper part of the middle sleeve. The bottom of the inner cap has two inverted U-shaped vents facing upwards, distributed on both radial sides. The inner wall of the inner cap has intermittent annular protrusions and two inverted U-shaped protrusions, also distributed on both radial sides. The line connecting the two inverted U-shaped vents and the line connecting the two inverted U-shaped protrusions intersects in a cross shape, meaning the two inverted U-shaped vents and protrusions are located at the four endpoints of the cross. The bottom of the inner cap has an outwardly folded inner cap retainer. The outer wall of the glass bottle mouth has an annular groove 71 and two vertical grooves, distributed on both radial sides of the annular groove. The intermittent annular protrusions of the inner cap engage with the annular groove at the bottle mouth, and the two inverted U-shaped protrusions engage with the two vertical grooves in a corresponding manner. The thickness of the intermittent annular protrusions is smaller than the opening size of the annular groove. The inner wall of the inner cap forms a first ventilation channel with the annular groove and the two vertical grooves. The problem with existing glass vacuum packaging bottles is that a sealing gasket is provided between the contact surface of the pump core assembly and the top of the inner valve bag. The sealing gasket is intended to achieve a seal at the joint between the pump core assembly and the inner valve bag. However, to ensure air can enter the glass bottle, not only is an inverted U-shaped air hole required at the bottom of the inner cap, but a vertical groove also needs to be created at the bottle mouth. Creating an inverted U-shaped air hole on the inner cap causes the inner valve bag to deform at the position corresponding to the inverted U-shaped air hole, thus preventing a seal between the inner valve bag and the pump core assembly. Creating a vertical groove at the bottle mouth complicates the bottle's structure and hinders cost reduction. Utility Model Content

[0035] Refer to the accompanying drawings of the specification of this utility model. Figures 1 to 12 A preferred embodiment of the present invention will be disclosed and described in the following description, wherein the emulsion bottle includes a bottle body assembly 10 and an emulsion pump assembly 20 mounted on the bottle body assembly 10.

[0036] Specifically, the bottle assembly 10 includes a bottle body 11 and a pouch 12. The bottle body 11 may be, but is not limited to, a glass bottle. The pouch 12 includes a bag body 121, a bag opening 122, and an overlap 123. The bag opening 122 extends upward from the bag body 121, and the overlap 123 extends outward from the bag opening 122. Preferably, the bag body 121, the bag opening 122, and the overlap 123 of the pouch 12 are integrally formed. In the uninflated state, the bag body 121 of the pouch 12 has a small volume, allowing the bag body 121 to extend into the interior of the bottle body 11, and the overlap 123 of the pouch 12 rests against the rim of the bottle body 11. Subsequently, the bag body 121 of the pouch 12 is allowed to inflate, causing the bag body 121 to expand inside the bottle body 11. The overlapping edge 123 of the pouch 12 has at least one notch 1231, which connects the interior and exterior of the bottle body 11. Preferably, the number of notches 1231 on the overlapping edge 123 of the pouch 12 is two or more. Preferably, the thickness of the opening 122 of the pouch 12 is greater than the thickness of the bag body 121, so that the bag body 121 is easily deformable and the opening 122 is not easily deformable.

[0037] The emulsion pump assembly 20 includes an emulsion pump body 21, which includes a pump housing 211, a flow control valve 212, a valve stem 213, a connecting rod 214, a piston 215, a cap 216, and a spring 217. The pump housing 211 has a pump chamber 2111 and an inlet port 2112 communicating with the pump chamber 2111. The flow control valve 212 is disposed on the pump housing 211 and is used to open and close the pump. The inlet port 2112 of the housing 211, wherein the valve stem 213 includes a piston seat 2131 and a rod 2132 extending upward from the piston seat 2131. The rod 2132 has a transverse hole 21321 and a longitudinal hole 21322. The transverse hole 21321 is adjacent to the piston seat 2131, and the longitudinal hole 21322 extends upward from the transverse hole 21321 to the end face of the rod 2132. Hole 21322 communicates with the transverse hole 21321. The piston 215 is fitted onto the rod body 2132 and the pump chamber 2111 is movably mounted on the pump housing 211. The connecting rod 214 has a rod hole 2141. The bottom of the connecting rod 214 is mounted on the rod body 2132. The longitudinal hole 21322 of the rod body 2132 communicates with the rod hole 2141 of the connecting rod 214. The cap 216 has a cap channel 2161. The cap 216 is mounted on the top of the connecting rod 214, and the cap channel 2161 of the cap 216 communicates with the rod hole 2141 of the connecting rod 214. The spring 217 is fitted onto the connecting rod 214, and the spring 217 is configured such that the top of the spring 217 remains stationary relative to the cap 216 and the bottom of the spring 217 remains stationary relative to the pump housing 211.

[0038] The emulsion pump assembly 20 further includes a sealing element 22, which is disposed around the pump housing 211 of the emulsion pump body 21. The emulsion pump body 21 is mounted on the bottle 11, and the bottom of the pump housing 211 extends into the interior of the bag 121 through the bag opening 122 of the bag 12. The bag opening 122 is sealed and bound to the sealing element 22 to prevent air leakage between the bag 12 and the sealing element 22.

[0039] In its natural state, the bottom of the piston 215 abuts against the piston seat 2131 of the valve stem 213, and the piston 215 prevents the transverse hole 21321 of the rod 2132 from connecting with the pump chamber 2111 of the pump housing 211. When the user initially presses the cap 216, the cap 216, the connecting rod 214, and the valve stem 213 move downward. On the one hand, the spring 217 is compressed and deformed to accumulate elastic potential energy. On the other hand, due to the large friction between the piston 215 and the pump housing 211, the position of the piston 215 remains unchanged. At this time, the transverse hole 21321 of the rod 2132 is exposed and connects to the pump chamber 2111 of the pump housing 211, and the bottom of the connecting rod 214 abuts against the piston 215.

[0040] When the user continues to press the cap 216, the cap 216, the connecting rod 214, and the valve stem 213 continue to move downward, and the connecting rod 214 pushes the piston 215 to move downward synchronously, so as to pump out the emulsion in the pump chamber 2111 of the pump housing 211 through the transverse hole 21321 and the longitudinal hole 21322 of the rod body 2132, the rod hole 2141 of the connecting rod 214, and the cap channel 2161 of the cap 216. In this process, on the one hand, the spring 217 is further compressed to accumulate elastic potential energy, and on the other hand, the flow control valve 212 is kept in the state of closing the liquid inlet hole 2112 of the pump housing 211.

[0041] In the first stage when the user releases the pressure on the cap 216, the spring 217 pushes the cap 216, the connecting rod 214 and the valve stem 213 upward during the return to the initial state. Due to the large friction between the piston 215 and the pump housing 211, the position of the piston 215 remains unchanged. At this time, the bottom of the piston 215 abuts against the piston seat 2131 of the valve stem 213, so that the piston 215 prevents the transverse hole 21321 of the rod body 2132 from communicating with the pump chamber 2111 of the pump housing 211.

[0042] In the second stage after the user abandons the cap 216, the spring 217 further returns to its initial state, pushing the cap 216, the connecting rod 214, and the valve stem 213 upward. During this process, the valve stem 213 pulls the piston 215 upward, causing a negative pressure environment to be formed in the pump chamber 2111 of the pump housing 211. Subsequently, the flow control valve 212 opens the inlet port 2112 of the pump housing 211 to allow the emulsion stored in the bag 12 to be replenished into the pump chamber 2111 of the pump housing 211 through the inlet port 2112. At the same time, air from the external environment is replenished into the interior of the bottle 11 through the notch 1231 of the lap edge 123 of the bag 12. After the pressure in the pump chamber 2111 of the pump housing 211 and the pressure in the bag 12 are restored to equilibrium, the flow control valve 212 closes the inlet port 2112 of the pump housing 211.

[0043] In the appendix Figures 1 to 12 In this specific example of the lotion bottle of the present invention shown, the sealing element 22 is fitted onto the pump housing 211 to surround the pump housing 211. That is, the pump housing 211 and the sealing element 22 are manufactured separately, and then the sealing element 22 is fitted onto the pump housing 211 to surround the pump housing 211. (See attached...) Figure 13 In this specific example of the emulsion bottle of the present invention shown, the sealing element 22 is integrally formed on the pump housing 211. For example, the pump housing 211 and the sealing element 22 can be injection molded by the same injection molding process, or after the pump housing 211 is injection molded, the sealing element 22 is formed on the pump housing 211 by an overmolding process, so that the sealing element 22 is disposed around the pump housing 211.

[0044] Reference Appendix Figures 3 to 5 , Figure 7 and Figure 8The sealing element 22 includes a sealing tube 221 and an overlapping ring 222 extending outward from the top of the sealing tube 221. The sealing tube 221 is inserted into the opening 122 of the pouch 12 so that the opening 122 is sealed and bound to the sealing element 22, preventing air leakage between the pouch 12 and the sealing tube 221. The overlapping edge 123 of the pouch 12 is clamped between the rim of the bottle body 11 and the overlapping ring 222 of the sealing element 22, preventing air leakage between the pouch 12 and the overlapping ring 222. In this way, the emulsion pump assembly 20 can reliably seal the opening of the pouch 12, creating a sealed environment inside the pouch 12. It is understood that, since the opening 122 of the bag 12 has a relatively thick dimension and is not easily deformed, the opening 122 will not deform during the process of inserting the sealing tube 221 into the opening 122 of the bag 12, so that the opening 122 can be sealed and bound by the sealing tube 221.

[0045] In the emulsion bottle of this utility model, the inner wall of the bag opening 122 of the pouch 12 is a complete arc surface, and the outer wall of the sealing tube 221 of the sealing element 22 is a complete arc surface. That is, the joint position of the bag opening 122 of the pouch 12 and the sealing tube 221 of the sealing element 22 are both complete arc surfaces. Thus, after the sealing tube 221 is inserted into the bag opening 122 of the pouch 12 and the bag opening 122 is allowed to be bound by the sealing tube 221, there will be no air leakage at the joint position of the pouch 12 and the sealing element 22. In addition, the upper surface of the overlapping edge 123 of the bag opening 122 is a complete plane, and the lower surface of the overlapping ring 222 of the sealing element 22 is a complete plane. That is, the joint position of the overlapping edge 123 of the bag 12 and the overlapping ring 222 of the sealing element 22 are both complete planes. Thus, after the overlapping ring 222 of the sealing element 22 is stacked on the overlapping edge 123 of the bag 12, there will be no air leakage at the joint position of the bag 12 and the sealing element 22.

[0046] Reference Appendix Figures 3 to 5The sealing element 22 has an annular groove 2211 in its sealing tube 221, and the pump housing 211 has an annular protrusion 2113. The annular protrusion 2113 of the pump housing 211 is engaged with the annular groove 2211 of the sealing tube 221, so that the sealing element 22 can be reliably fitted onto the pump housing 211, preventing the sealing element 22 from falling off the pump housing 211. Optionally, in other examples of the lotion bottle of this utility model, the annular groove 2211 can be provided on the pump housing 211, and correspondingly, the annular protrusion 2113 can be provided on the sealing tube 221. The annular protrusion 2113 of the sealing tube 221 is engaged with the annular groove 2211 of the pump housing 211, so that the sealing element 22 can be reliably fitted onto the pump housing 211, preventing the sealing element 22 from falling off the pump housing 211.

[0047] Continue to refer to the appendix Figures 3 to 8 The emulsion pump body 21 further includes an inner locking cap 218, which is used to install the emulsion pump body 21 onto the bottle body 11.

[0048] Specifically, the inner locking cover 218 includes a locking cover plate 2181 and a locking cover wall 2182. The locking cover wall 2182 extends integrally downward from the periphery of the locking cover plate 2181 to form a locking cover cavity 2183 between the locking cover plate 2181 and the locking cover wall 2182. The locking cover plate 2181 has a cover hole 21811, which communicates with the locking cover cavity 2183. The inner diameter of the cover hole 21811 is smaller than the outer diameter of the top edge of the pump housing 211. The inner locking cap 218 has an internal thread on its locking cap wall 2182 and an external thread on its bottle body 11. When the internal thread of the locking cap wall 2182 and the external thread of the bottle body 11 engage with each other to screw the inner locking cap 218 onto the bottle body 11, the locking cap plate 2181 of the inner locking cap 218 presses the top edge of the pump housing 211, the overlapping ring 222 of the sealing element 22, and the overlapping edge 123 of the bag 12 against the top edge of the bottle body 11. This allows the overlapping ring 222 of the sealing element 22 and the top edge of the bottle body 11 to clamp the overlapping edge 123 of the bag 12. This not only prevents the bag 12 from falling entirely into the bottle body 11, but also ensures that the overlapping ring 222 of the sealing element 22 fits tightly against the overlapping edge 123 of the bag 12, preventing air leakage between them.

[0049] Furthermore, the inner locking cap 218 has at least one elastic blocking arm 2184, which extends obliquely downward from the bottom edge of the locking cap wall 2182. Correspondingly, the bottle body 11 has at least one blocking block 111. When the locking cap wall 2182 of the inner locking cap 218 is screwed onto the bottle body 11, the blocking block 111 of the bottle body 11 can push the elastic blocking arm 2184 of the inner locking cap 218 to deform upward. After the locking cap wall 2182 of the inner locking cap 218 is screwed onto the bottle body 11, the elastic blocking arm 2184 of the inner locking cap 218 blocks the blocking block 111 of the bottle body 11, preventing the inner locking cap 218 from rotating in the opposite direction, so that the inner locking cap 218 will not become loose. In other words, by providing the elastic blocking arm 2184 on the inner locking cap 218 and the blocking block 111 on the bottle body 11, the inner locking cap 218 can only be rotated in one direction.

[0050] Reference Appendix Figures 6 to 8 The inner locking cap 218 has at least one clearance notch 21821 at the bottom edge of the locking cap wall 2182. The elastic blocking arm 2184 is suspended at the opening of the clearance notch 21821 of the locking cap wall 2182 to reduce the height of the elastic blocking arm 2184 protruding from the bottom edge of the locking cap wall 2182. When the locking cap wall 2182 of the inner locking cap 218 is screwed onto the bottle body 11, the blocking block 111 of the bottle body 11 can push the elastic blocking arm 2184 of the inner locking cap 218 into the clearance notch 21821 of the locking cap wall 2182.

[0051] In the appendix Figures 1 to 12 In this specific example of the emulsion bottle of the present invention shown, the number of elastic blocking arms 2184 of the inner locking cap 218 is two, correspondingly, the number of clearance notches 21821 of the locking cap wall 2182 of the inner locking cap 218 is two, and the number of blocking blocks 111 of the bottle body 11 is two.

[0052] Continue to refer to the appendix Figures 3 to 5 , Figure 7 and Figure 8The emulsion pump body 21 includes an assembly ring 219, which is fitted onto the connecting rod 214. The bottom of the assembly ring 219 extends into the pump chamber 2111 of the pump housing 211 and is fixedly installed on the pump housing 211. For example, the bottom of the assembly ring 219 and the pump housing 211 are interlocked to fix the bottom of the assembly ring 219 on the pump housing 211. The assembly ring 219 is used to limit the maximum upward movement of the piston 215. The top of the assembly ring 219 hooks onto the edge of the locking plate 2181 of the inner locking cover 218 that forms the cover hole 21811. Thus, the assembly ring 219 connects the pump housing 211 and the inner locking cover 218.

[0053] The bottom of the spring 217 abuts against the mounting ring 219 so that the bottom of the spring 217 remains stationary relative to the pump housing 211, and the top of the spring 217 abuts against the connecting rod 214 so that the top of the spring 217 remains stationary relative to the cap 216.

[0054] Furthermore, the emulsion pump body 21 includes a middle sleeve 2110, which is fitted onto the inner locking cover 218 to conceal the inner locking cover 218 within the middle sleeve 2110. The bottom of the cap 216 extends into the middle sleeve 2110, thus the middle sleeve 2110 and the cap 216 cooperate to conceal the connecting rod 214 and the spring 217. Preferably, the locking cover wall 2182 of the middle sleeve 2110 and the inner locking cover 218 engages with each other to reliably fit the middle sleeve 2110 onto the inner locking cover 218.

[0055] Furthermore, the emulsion pump body 21 includes a suction tube 21110, the top of which is inserted into the bottom of the pump housing 211, and the bottom of which extends into the bottom of the bag body 121 of the pouch 12.

[0056] Reference Appendix Figure 1 , Figures 3 to 5 , Figure 7 and Figure 8 The lotion bottle includes a cap 30, which is detachably mounted on the inner sleeve 2110. When the cap 30 is mounted on the inner sleeve 2110, the cap 30 covers the cap 216 to prevent the cap 216 from being accidentally pressed. After the cap 30 is removed from the inner sleeve 2110, the cap 216 is exposed.

[0057] Appendix Figures 9 to 12 The filling process of the emulsion bottle of this invention is shown. (See attached document.) Figure 9 In the uninflated state, the bag body 121 of the pouch 12 is inserted into the interior of the bottle body 11, allowing the overlapping edge 123 of the pouch 12 to rest against the rim of the bottle body 11. Since the lower surface of the overlapping edge 123 of the pouch 12 has a notch 1231, the notch 1231 of the pouch 12 connects the interior and exterior of the bottle body 11. Subsequently, air is inflated into the bag body 121 through the bag opening 122, causing the bag body 121 of the pouch 12 to expand inside the bottle body 11. (See attached diagram) Figure 10 The emulsion is poured into the bag body 121 through the bag opening 122 of the bag 12. (See attached image) Figure 11 After the suction tube 21110 of the emulsion pump body 21, the bottom of the pump housing 211, and the bottom of the sealing tube 221 of the sealing element 22 are inserted into the opening 122 of the pouch 12, the emulsion pump assembly 20 is rotated to allow the inner locking cap 218 to be screwed onto the bottle body 11. After the inner locking cap 218 is screwed onto the bottle body 11, the opening 122 of the pouch 12 is sealed and bound to the sealing tube 221 of the sealing element 22 to prevent air leakage at the joint. At the same time, the lower surface of the overlapping ring 222 of the sealing element 22 is tightly fitted to the upper surface of the overlapping edge 123 of the pouch 12 to prevent air leakage at the joint. (See attached diagram) Figure 12 The cover 30 is installed on the middle sleeve 2110.
