Description

Technical Field

[0001] This utility model belongs to the field of cosmetic bottle technology, specifically relating to a pump-discharge cosmetic packaging bottle. Background Technology

[0002] Both cosmetics and skincare products are commonly used personal care products. Taking cosmetics as an example, many packaging bottles have pump-operated dispensing mechanisms, but the pump heads of these bottles cannot be locked again once opened. CN202021396261.7 discloses a replaceable needle-type dropper; however, this replaceable needle-type dropper may cause accidental dispensing by pressing the pump head in daily life, affecting the user experience, especially when users are carrying it out. Due to the close arrangement and relative movement of items, accidental dispensing is very likely to occur unnoticed. This is not only inconvenient for users to carry, but may also cause unnecessary waste and affect the user experience. Utility Model Content

[0003] This invention addresses the technical problem that existing cosmetic packaging bottles with pumps cannot be locked after being opened, causing inconvenience to users in terms of use and carrying. The purpose is to provide a cosmetic packaging bottle with pump dispensing.

[0004] The pump-discharge cosmetic packaging bottle of this utility model includes: The outer bottle assembly has an outer bottle, a middle ring disposed on the upper part of the outer bottle, and a locking cap that can be rotatably inserted through the middle ring. The locking cap can rotate back and forth circumferentially between the open and closed positions of the middle ring, thereby realizing a self-opening and closing function. An inner bottle assembly having an inner bottle located inside the outer bottle; A pump assembly having a pump core passing through the opening of the inner bottle and a pump cap covering the opening of the inner bottle and sealing the pump core. When the locking cover is rotated to the closed position of the middle ring, the bottom of the locking cover abuts against the pump cover longitudinally, achieving self-locking; when the locking cover is rotated to the open position of the middle ring, the bottom of the locking cover is offset from the pump cover, thereby opening, allowing for pressing to discharge material.

[0005] Preferably, The lower part of the lock cover has at least a pair of symmetrically arranged lower abutment posts; The upper part of the pump cover has at least a pair of symmetrically arranged upper abutment posts and a circumferential clearance position located between two adjacent lower abutment posts; When the lock cover is rotated to the closed position of the middle ring, the lower abutment of the lock cover abuts against the corresponding upper abutment of the pump cover longitudinally to lock it; when the lock cover is rotated to the open position of the middle ring, the lower abutment of the lock cover is offset from the corresponding upper abutment of the pump cover and is located within the circumferential clearance position of the pump cover to unlock it.

[0006] Preferably, The middle ring has an outer wall and an inner wall, and at least one pair of symmetrically arranged connecting bridges that interconnect the outer wall and the inner wall of the middle ring. There is a fan-shaped hole between two adjacent connecting bridges, and the connecting bridges are located above the circumferential clearance position. The lower abutment of the lock cover passes through the fan-shaped hole of the middle ring and is snapped into the outer wall of the middle ring.

[0007] Preferably, The inner wall of the fan-shaped hole has a tactile bump that the lock cover can rotate over. The two sides of the tactile bump are the open position and the closed position of the middle ring, respectively.

[0008] Preferably, The upper part of the pump cover also has at least one pair of symmetrically arranged upper baffles that are higher than the upper abutment post, and the upper abutment post is provided on the outer surface of the lower half wall of the corresponding upper baffle. When the locking cover is rotated to the closed position of the middle ring, the lower abutment of the locking cover abuts longitudinally against the corresponding upper abutment of the pump cover, and the lower abutment is sandwiched between the upper baffle and the outer wall of the middle ring to prevent the lower abutment of the locking cover from being deformed by pressure and disengaging from the fan-shaped hole.

[0009] Preferably, The outer bottle assembly also has a top cover that is snapped onto the locking cap and a discharge nozzle that is airtightly connected to the locking cap; the middle ring has a ring core in the middle of the inner wall of the middle ring; The pump head of the pump core of the pump assembly is snapped onto the core of the middle ring; the pump core, the middle ring, and the discharge nozzle can be connected in communication; Preferably, the outer wall of the middle ring is snapped onto the upper inner wall of the outer bottle; Preferably, the inner bottle is snap-fitted to the pump cap; Preferably, the pump core is connected to the bottle opening of the inner bottle by a tight, airtight connection.

[0010] Preferably, The inner bottle assembly also has an airtight piston located at the bottom of the inner bottle and a snap-fit ​​cap located at the bottom of the inner bottle, the cap having an air intake channel communicating with the outside.

[0011] Preferably, The outer wall of the inner bottle has at least two pairs of spaced-apart inner bottle rotation limiting ribs arranged axially. The inner wall of the outer bottle has at least two U-shaped ribs that are arranged along the axial direction to limit the rotation of the outer bottle; Each pair of inner bottle rotation limiting ribs is correspondingly engaged between the outer bottle rotation limiting U-shaped ribs to restrict the rotation of the inner bottle relative to the outer bottle.

[0012] Preferably, The lower half of the outer wall of the inner ring has at least one inner ring push plate, which is disposed within one of the outer bottle rotation limiting U-shaped ribs of the outer bottle. Preferably, there are two inner bottle rotation limiting ribs, two outer bottle rotation limiting U-shaped ribs, and two inner ring push plates.

[0013] Preferably, One end of the pair of outer bottle rotation limiting U-shaped ribs is set as a transition jump rib with a thickness lower than the overall thickness of the U-shaped rib; Each pair of inner bottle rotation limiting ribs is connected to an inclined rib at its top; the lower end of the inclined rib is located on one side of the over-gear jumping rib. When the middle ring is rotated, the damping ribs on the edge of the middle ring push plate can pass over the over-speed ribs of the outer bottle and abut against the inclined ribs on the outer wall of the inner bottle, thereby pushing out the inner bottle assembly and the pump assembly.

[0014] The positive and progressive effects of this utility model are as follows: 1) This utility model's pump-discharge cosmetic packaging bottle features a locking cap, a pump cap, and a central ring. The central ring has an open and a closed position. When the locking cap is rotated to the closed position, its bottom is longitudinally pressed against the pump cap, preventing further longitudinal movement and thus locking the cap to prevent dispensing. When the locking cap is rotated to the open position, its bottom is offset from the pump cap, allowing the pump core to move longitudinally under the pressure of air from the bottom, thus pumping out the material. This utility model's pump-discharge cosmetic packaging bottle achieves rotational locking and unlocking, with simple overall operation. It is particularly suitable for users to carry when traveling, effectively avoiding unnecessary waste during transport and improving the user experience. Attached Figure Description

Detailed Implementation

[0016] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0017] like Figure 1 and Figure 2 As shown, the pump-discharge cosmetic packaging bottle of this utility model includes an outer bottle assembly 1, an inner bottle assembly 2, and a pump assembly 3. The outer bottle assembly 1 includes an outer bottle 11, a middle ring 12, a locking cap 13, a discharge nozzle 14, and a top cap 15. The inner bottle assembly 2 includes an inner bottle 21, a piston 22, and a pressure cap 23. The pump assembly 3 includes a pump core 31 and a pump cover 32.

[0018] In this example, continue as follows Figure 3 , Figure 4 and Figure 5 As shown, the pump core 31 is located at the innermost side of the cosmetic packaging bottle from which the pump is dispensed. The lower section of the pump core 31 passes through the opening of the inner bottle 21. On one hand, the pump core 31 is airtightly connected to the opening of the inner bottle 21 via a clamping plate 34. On the other hand, the bottom of the pump core 31 is also connected to the inner cavity of the inner bottle 21 containing the material (such as liquid or emulsion) to draw out the material pumped out of the inner bottle 21. Continuing as... Figure 4 and Figure 5 As shown, a pump cover 32 is also connected to the outer periphery of the bottle opening of the inner bottle 21 and the outer periphery of the pump core 31. The pump cover 32 is divided into an upper section, a middle section, and a lower section. The lower section is fastened to the inner bottle 21. Specifically, as shown... Figure 4 , Figure 5 and Figure 6 As shown, the lower section of the pump cover 32 is fastened to the outer wall of the inner bottle 21 via a snap fastener, thereby restricting the relative longitudinal movement of the pump cover 32 and the inner bottle 21. Of course, the snap fastener can be installed on the inner wall of the pump cover 32 or on the outer wall of the inner bottle 21's opening, while the corresponding interlocking slots are installed on the outer wall of the inner bottle 21's opening or the inner wall of the pump cover 32. The middle section of the pump cover 32 tightly surrounds the outer periphery of the middle part of the pump core 31, thereby making the connection between the inner bottle 21 and the pump core 31 more secure. The upper section of the pump cover 32 passes through the middle ring 12, and includes at least a pair of symmetrically arranged lockable caps 13 that cooperate to form rotatable locking and unlocking upper abutment posts 321 and circumferential clearance positions 322 located between adjacent upper abutment posts. Specifically, continuing as... Figure 4 and Figure 8 As shown, the middle ring 12 has an outer wall 121, an inner wall 122, and a core 124 located in the middle of the inner wall 122. The core 124 also includes an upper section, a middle section, and a lower section. The lower section of the core 124 passes through the top of the pump core 31, and the central cavity of the core 124 is connected to the pump core 31. The upper end of the pump core 31 is airtightly fitted to the lower section of the core 124 via an interference fit. The middle section of the core 124 is fixedly connected to the inner wall 122 of the middle ring via a connecting plate. The outer circumferential wall of the upper section of the core 124 is airtightly connected to the lock cover 13. Its upper end is connected to the discharge nozzle 14 fixed on the lock cover 13. Of course, in this example, the discharge nozzle 14 is airtightly fixed to the lock cover 13 via an interference fit to further ensure the airtightness of the connection between the core 124, the lock cover 13, and the discharge nozzle 14. Continuing as... Figure 8 As shown, the upper section of the inner wall 122 of the middle ring and the outer wall 121 of the middle ring are fixedly connected by at least a pair of symmetrically arranged interconnecting connecting bridges 123. There is a fan-shaped hole 125 between two adjacent connecting bridges 123. The middle of the inner side wall of the fan-shaped hole 125 is provided with a shift-sensing protrusion 126, which divides the entire fan-shaped hole 125 into an open position 125a and a closed position 125b. The open position 125a is in the same longitudinal direction as the circumferential clearance position 322 of the upper section of the pump cover 32, while the closed position 125b is in the same longitudinal direction as the upper abutment post 321 of the pump cover 32.

[0019] Continue as Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, the locking cover 13 is a rotatable locking cover 13, with at least a pair of symmetrically arranged lower abutment posts 131 at its lower part. Typically, the number of lower abutment posts 131 corresponds to the number of fan-shaped holes 125 and upper abutment posts 321 of the pump cover 32; in this example, there are four in each case. The lower abutment posts 131 of the locking cover 13 can cooperate with the upper abutment posts 321 of the pump cover 32 and the circumferential clearance positions 322 located between adjacent upper abutment posts 321 to form a rotatable locking and unlocking function. Specifically, the lower abutment posts 131 pass through the fan-shaped holes 125 of the middle ring 12 and are connected to the inner sidewall of the outer wall 121 of the middle ring by a snap-fit, thereby restricting the relative movement of the locking cover 13 and the middle ring 12 in the longitudinal direction. The lower abutment posts 131 passing through the fan-shaped holes 125 can rotate back and forth between the open position 125a and the closed position 125b within the corresponding fan-shaped holes 125, and the rotation is sensed by the transition tactile protrusions 126 at the dividing points. For example, when the locking cover 13 rotates from the open position 125a, passing the shift-jumping protrusion 126 (which the user can feel), it rotates to the closed position 125b, until one side of the lower abutment 131 of the locking cover 13 is blocked and limited by the side wall of the fan-shaped hole 125. At this time, the four lower abutments 131 of the locking cover 13 are respectively longitudinally abutting against the corresponding four upper abutments 321 of the pump cover 32. At the same time, since the lower abutment 131 has completely rotated from the open position 125a to the closed position 125b, the shift-jumping protrusion 126 is relatively shifted to the other side of the lower abutment 131, which forms a certain relative reverse rotation resistance. By limiting the lower abutment 131 in the closed position 125b, the pump cover 32 is longitudinally locked, so that the pump core 31 cannot be pressed, that is, a relative locking state is achieved (e.g., Figure 9 (As shown). When the locking cap 13 rotates in the reverse direction from the closed position 125b to the open position 125a, similarly, it first passes the transition point 126, and then until one side of the lower abutment 131 is blocked and limited by the opposite side wall of the fan-shaped hole 125. The four lower abutment pins 131 of the locking cap 13 are respectively offset from the corresponding upper abutment pins 321 of the pump cover 32, and completely move into the circumferential clearance position 322 of the pump cover 32. At this time, the connecting bridge 123 between the inner wall 122 of the middle ring and the outer wall 121 of the middle ring is also located in the circumferential clearance position 322, thus having longitudinal movement space to apply pressure to the cap 23 of the inner bottle assembly 2 and press the material longitudinally, that is, to achieve a relatively unlocked state (as shown). Figure 10 (As shown). Similarly, since the gear has rotated completely from the closed position 125b to the open position 125a, the shift-sensor protrusion 126 shifts in the opposite direction to one side of the lower abutment post 131, thus creating a certain relative reverse rotation resistance. This further limits the lower abutment post 131 to the open position 125a, achieving relative stability in the unlocked state. The overall structure is simple and easy to operate, making it particularly suitable for users to carry when out and about. It effectively avoids unnecessary waste during transport and improves the user experience.

[0020] And continue as Figure 7 and Figure 9 As shown, to further ensure the locking effect of the locking cover 13, an upper baffle 323 is provided on the inner wall of the corresponding upper abutment 321 on the upper section of the pump cover 32. The upper baffle 323 passes through and abuts against the outer wall of the inner wall 122 of the middle ring, and the upper baffle 323 is higher than the upper abutment 321. That is, when the locking cover 13 is rotated to the closed position 125b, the lower end of the lower abutment 131 of the locking cover 13 longitudinally abuts against the corresponding upper abutment 321 of the pump cover 32, and one end of the lower abutment 131 is fixed to the inner wall of the outer wall 121 of the middle ring by the above-mentioned snap-fit ​​method, while the other side is pressed by the upper baffle 323. That is, the lower abutment 131 is sandwiched between the upper baffle 323 and the outer wall 121 of the middle ring to prevent the lower abutment 131 of the locking cover 13 from being deformed by pressure and disengaging from the fan-shaped hole 125. And continue as Figure 9 As shown, a switch is also provided on the outer wall of the lock cover 13 for easy user identification, namely, a direction indicator for unlocked and locked states.

[0021] To prevent relative rotation between the inner bottle 21 and the outer bottle 11, the outer surface of the inner bottle 21 is provided with at least two spaced-apart, axially arranged inner bottle rotation limiting ribs 211, and the inner wall of the outer bottle 11 is also provided with at least two axially arranged outer bottle rotation limiting U-shaped ribs 111. Each inner bottle rotation limiting rib 211 is engaged between two adjacent outer bottle rotation limiting U-shaped ribs 111 to restrict relative rotation between the inner and outer bottles. Continuing as... Figure 13 As shown, the lower half of the outer wall of the middle ring 12 has at least one middle ring push plate 1213, which is disposed within one of the outer bottle rotation limiting U-shaped ribs of the outer bottle 11. In this example, it is preferable to have two middle ring push plates 1213, two inner bottle rotation limiting ribs 211, and two outer bottle rotation limiting U-shaped ribs 111, with clearance grooves 1212 formed between adjacent middle ring push plates 1213. As mentioned above, the middle ring 12 is fastened to the outer bottle 11, and, continuing as... Figure 10 , Figure 11 and Figure 12 As shown, to prevent the middle ring 12 from rotating during the rotation of the locking cap 13, the outer wall 121 of the middle ring is provided with damping ribs 1211 on both sides of the middle ring push plate 1213. The damping ribs 1211 abut against the inner side of the outer bottle rotation limiting U-shaped rib 111. That is, the outer bottle rotation limiting U-shaped rib 111 surrounds the edge of the middle ring push plate 1213 to restrict the middle ring 12 from being rotated.

[0022] Specifically, such as Figure 12As shown, one end of the outer bottle rotation limiting U-shaped rib 111 is set as a pass-through flex rib 1111 with a thickness lower than the overall thickness of the U-shaped rib (the reason for setting a thinner pass-through flex rib 1111 is explained later in the replacement of the inner bottle assembly 2 and the pump assembly 3). When the rotating lock cap 13 is unlocked and locked, the damping limiting force formed between the damping rib 1211 and the pass-through flex rib 1111 of the outer bottle 11 is also greater than the friction force between the lock cap 13 and the pass-through flex rib 126 on the inner side wall of the fan-shaped hole 125 of the middle ring 12, so that when the lock cap 13 and the middle ring 12 rotate relative to each other, the outer bottle 11 and the middle ring 12 cannot rotate relative to each other.

[0023] In this example, such as Figure 14 As shown, the inner bottle assembly 2 and the pump assembly 3 together form a replaceable assembly. By rotating the central ring 12, the inner bottle assembly 2 and the pump assembly 3 can be detached from the outer bottle assembly 1 for replacement. Continuing as... Figure 10 and Figure 11 As shown, each inner bottle rotation limiting rib 211 has an inclined rib 2111 connected to its top. The two ends of the inclined rib 2111 are a low end and a high end, respectively. The low end of the inclined rib 2111 is located on the outer side of the over-gear bounce sensing rib 1111. The middle ring push plate 1213 abuts against the lower end of the inclined rib 2111 and is located on the inner side of the over-gear bounce sensing rib 1111. The over-gear bounce sensing rib 1111 and the damping protrusion rib 1211 at the edge of the middle ring push plate 1213 form a bounce sensing connection, which is used to determine the rotation replacement process. Specifically, before replacement, the damping plate 1213 of the middle ring is damped and locked in the corresponding outer bottle rotation limit U-shaped rib 111. When the middle ring 12 is rotated for replacement, the damping rib 1211 on one side edge of the middle ring push plate 1213 begins to pass over the over-speed jump rib 1111 on the outer bottle 11, so that the user can feel the start of replacement. Then the middle ring 12 continues to rotate, so that the middle ring push plate 1213 pushes the inner bottle 12 outward along the lower end to the upper end of the inclined rib 2111, thereby pushing out the entire inner bottle 12, the inner bottle assembly 2, and the replacement assembly. Then, the old replacement component is removed and the new replacement component is inserted. At this time, the inner bottle tilting rib 2111 abuts against the middle ring push plate 1213. As the replacement component enters, the middle ring automatically rotates until the middle ring damping rib 1211 passes the outer bottle bounce-sensing rib 1111. At this point, the user can feel the bounce again. The middle ring push plate 1213 is located within the outer bottle rotation limiting U-shaped rib 111, and the replacement is complete. After the new inner bottle component and pump component are installed in the packaging bottle, the damping rib 1211 of the middle ring push plate 1213 abuts against the outer bottle rotation limiting U-shaped rib 111 and the over-gear bounce-sensing rib 1111 on the inner side wall of the outer bottle 11. This effectively prevents the middle ring 12 from being accidentally rotated when the locking cap 13 is turned to lock or unlock.

[0024] In addition, the pump core 31 is a vacuum pump core, and a piston 22 is airtightly connected to the inner bottom of the inner bottle 21 for holding materials. A pressure cap 23 is placed on the bottom of the inner bottle 21, and the pressure cap 23 is attached to the bottom of the inner bottle 21 by a snap-fit ​​connection. The pressure cap 23 has an air inlet channel communicating with the outside. When the piston 22 receives air pressure, it forces the material through the vacuum pump core 31 and out of the bottle via the discharge nozzle. Continuing... Figure 1 As shown, a top cover 15 is also provided above the locking cover 13 and the discharge nozzle 14. The top cover 15 is also connected to the locking cover 13 by a snap fastener. Similarly, the top cover 15 may have a snap fastener on its inner side wall and a corresponding slot on the outer side wall of the locking cover 13; or the top cover 15 may have a slot on its inner side wall and a corresponding snap fastener on the outer side wall of the locking cover 13; or a series of slots may be provided with corresponding snap fasteners at intervals or in a series of corresponding slots.
