Description

Technical Field

[0001] This utility model relates to the field of packaging container technology, specifically to a cosmetic packaging bottle with a shoulder sleeve. Background Technology

[0002] Cosmetic bottles are containers used to hold cosmetics. A cosmetic bottle typically consists of a bottle body and a cap. The cap needs to be easy for users to open and close, while ensuring a tight seal to prevent product leakage or the entry of external contaminants. The cap design needs to coordinate with the bottle body and overall packaging style to enhance the product's overall aesthetics. Existing cosmetic bottles can be enhanced by adding shoulder sleeves to the bottle body. These shoulder sleeves can be made of different materials, colors, and textures to increase the cosmetic bottle's visual appeal and make it more personalized and fashionable, thereby increasing customers' desire to purchase.

[0003] The installation of shoulder sleeves typically requires corresponding fasteners and clips on the bottle body. However, there are some problems with the installation: when pressing the shoulder sleeve into the shoulder of the bottle body, the shoulder of the bottle body is prone to collapse, causing the shoulder sleeve to fail to be secured to the bottle body. In addition, the common shoulder sleeves are oval-shaped, and the two ends of the shoulder sleeves along the long axis of the newly produced shoulder sleeves will be warped and deformed. When the shoulder sleeve is pressed into the shoulder of the bottle body, even if it is secured by clips, the gap between the shoulder sleeve and the two sides of the bottle body will be relatively obvious, affecting the appearance of the packaged bottle. Moreover, due to this warping deformation, the shoulder sleeve is prone to swaying from side to side during the installation process, and it may be crooked when pressing the shoulder sleeve in, resulting in a high defect rate. Utility Model Content

[0004] The purpose of this utility model is to provide a cosmetic packaging bottle with a shoulder sleeve, which solves the problems of the shoulder of the bottle easily collapsing and the shoulder sleeve easily tilting during the process of pressing the shoulder sleeve into the bottle body.

[0005] To achieve the above objectives, the solution of this utility model is: A cosmetic packaging bottle with a shoulder sleeve includes a bottle body, a shoulder sleeve, and a bottle cap. The upper end of the bottle body has a boss, and a dispensing head communicating with the inner cavity of the bottle body is provided on the boss. A shoulder portion of the bottle body is formed between the upper edge of the bottle body and the boss. The shoulder sleeve is fitted onto the boss. Multiple reinforcing blocks abut against the shoulder sleeve are provided on the shoulder portion. The shoulder sleeve has an outer ring abutting against the upper edge of the bottle body and an inner ring abutting against the shoulder portion. The inner ring has grooves for the reinforcing blocks to be inserted. A ring groove is formed along the periphery of the side wall of the boss. A protrusion engaging with the ring groove is provided on the side wall of the inner ring. Symmetrically arranged breaks are provided on the protrusion. Multiple reinforcing ribs are provided on the shoulder sleeve at positions corresponding to the outer ring and the inner ring. The bottle cap and the dispensing head are connected together by threads.

[0006] The top surface of each of the reinforcing blocks is an obstacle avoidance slope.

[0007] The cross-section of the bottle is an ellipse that is narrow at both ends and wide in the middle, and the shape of the shoulder sleeve is adapted to the shape of the cross-section of the bottle.

[0008] Each of the aforementioned disconnected portions is located at both ends of the shoulder sleeve in the short axis direction.

[0009] Limiting protrusions are provided at both ends of the shoulder of the bottle along the long axis, and the limiting protrusions are located between the outer ring and the inner ring.

[0010] The liquid outlet head is provided with a liquid outlet, and an inner plug is installed inside the liquid outlet head. One end of the inner plug is the liquid inlet end, and the other end of the inner plug is the liquid outlet end. A liquid outlet channel is opened inside the inner plug, and the liquid outlet end of the inner plug extends out of the liquid outlet. Multiple protrusions are provided on the end face of the liquid inlet end of the inner plug. Stainless steel balls that abut against each of the protrusions are provided inside the bottle body, and a liquid inlet gap is formed between the stainless steel balls and each of the protrusions.

[0011] The bottle cap includes an outer cap and an inner cap. The inner cap has a threaded hole on its lower inner side. The liquid outlet has a threaded section on its outer side that is threaded to engage with the threaded hole. The inner cap has a positioning block at the bottom corresponding to the threaded hole. The liquid outlet has a positioning groove at the bottom of its outer side that engages with the positioning block. The liquid outlet has a guide block at the position corresponding to the positioning groove.

[0012] The inner cover is provided with an inner sealing post and an outer sealing ring at the top of the threaded hole. The inner sealing post is inserted into the liquid outlet end of the inner plug and makes sealing contact with the liquid outlet end. The outer sealing ring is sealed and sleeved on the outside of the liquid outlet end of the inner plug.

[0013] The upper end of the inner cover is open, and at least one vertical strip-shaped slot is symmetrically opened at the upper end of the inner cover. The inner wall of the outer cover is provided with a first locking strip that is inserted into each of the strip-shaped slots.

[0014] The lower outer side of the inner cover is provided with a second transverse locking strip, and the inner wall of the outer cover is provided with a transverse locking groove that engages with the second locking strip.

[0015] With the above structure, the cosmetic packaging bottle with shoulder sleeve of this utility model has the following beneficial effects: First, the upper edge of the bottle body and the boss form the shoulder of the bottle body. Multiple reinforcing blocks are provided on the shoulder to abut against the shoulder sleeve. By providing reinforcing blocks on the shoulder of the bottle body, the strength is increased. During the process of pressing the shoulder sleeve into the bottle body, the shoulder can be prevented from collapsing and will not affect the installation of the shoulder sleeve. Secondly, since the shoulder sleeve is hollow, a weld line will be left on the opposite side of the glue injection point on the shoulder sleeve during production. The strength at the weld line position is relatively poor. Therefore, an annular groove is opened along the periphery on the side wall of the boss of the bottle body, and a protrusion is provided on the side wall of the inner ring of the shoulder sleeve to engage with the annular groove. The protrusion is symmetrically provided with a break, so that the protrusion is not a full circle structure, making it easier to press the shoulder sleeve into the bottle body, and the weld line position is not easy to break, thus reducing the defect rate. Finally, multiple reinforcing ribs are provided at the position between the outer and inner rings of the shoulder sleeve, which can effectively reduce the warping and deformation of the shoulder sleeve and make the gap between the shoulder sleeve and the protrusion of the bottle body evenly distributed, making it more aesthetically pleasing.

[0016] Furthermore, the cross-section of the bottle body is an ellipse that is narrow at both ends and wide in the middle. The shape of the shoulder sleeve is adapted to the shape of the cross-section of the bottle body. Each of the disconnected parts is respectively set at both ends of the short axis direction of the shoulder sleeve. With this arrangement, when the shoulder sleeve is pressed into the shoulder of the bottle body, the two ends of each protrusion first fall on the shoulder of the bottle body, forming a stable support point, which will not sway left and right, and is easy to assemble.

[0017] Furthermore, the inner cover is provided with an inner sealing post and an outer sealing ring at the top of the threaded hole. The inner sealing post is inserted into the liquid outlet end of the inner plug and makes sealing contact with the liquid outlet end. The outer sealing ring is sealed and sleeved on the outside of the liquid outlet end of the inner plug. With this arrangement, the inner plug and the inner cover adopt double sealing from the inside and outside, which improves the sealing effect. In addition, the outer sealing ring also has a guiding function. When the inner sealing post of the inner cover is about to rotate and insert into the liquid outlet end of the inner plug, if it becomes misaligned, the outer sealing ring can play a guiding role to prevent the inner sealing post from crushing the liquid outlet end of the inner plug.

[0018] Furthermore, when the contents of the bottle need to be poured out, if the contents are thin and slippery, the amount poured out cannot be controlled, easily resulting in too much and waste. Therefore, an inner plug is installed inside the dispensing head, and a dispensing channel is opened inside the inner plug. The dispensing end of the inner plug extends out of the dispensing port, and multiple protrusions are provided on the end face of the inlet end of the inner plug. Stainless steel balls are provided inside the bottle that abut against each of the protrusions. The stainless steel balls and each protrusion form an inlet gap. With this design, when the bottle is turned upside down, the contents must flow out through the narrow dispensing channel at a slower flow rate, and the stainless steel balls will fall on the protrusions on the inlet end of the inner plug, so that the contents can only flow from the inlet gap into the dispensing channel, which can prevent a large amount of contents from flowing out.

Detailed Implementation

[0021] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0022] A cosmetic packaging bottle with a shoulder sleeve, such as Figures 1-2 As shown, the bottle includes a bottle body 1, a shoulder sleeve 2, and a bottle cap. A boss 11 is provided at the upper end of the bottle body 1, and a liquid outlet head 12 communicating with the inner cavity of the bottle body 1 is provided on the boss 11. The upper edge of the bottle body 1 and the boss 12 form a shoulder of the bottle body 1.

[0023] like Figures 1-4As shown, the bottle cap includes an outer cap 3 and an inner cap 4. The inner cap 4 has a threaded hole 41 on its lower inner side. The dispensing head 12 has a threaded section 121 on its outer side that engages with the threaded hole 41. A positioning block 42 is located at the bottom of the inner cap 4 corresponding to the threaded hole 41. A positioning groove 122 is located at the bottom of the outer side of the dispensing head 12, engaging with the positioning block 42. Guide blocks 123 are located at both ends of the dispensing head 12 corresponding to the positioning groove 122. Each guide block 123 has a guiding surface that facilitates the sliding of the positioning block 42 into and out of the positioning groove 122. This design allows the inner cap 3 and the dispensing head 12 to be connected together by threads, resulting in a more secure connection.

[0024] The upper end of the inner cover 4 is open, and at least one vertical strip-shaped latch 43 is symmetrically provided on the upper end of the inner cover 4. The inner wall of the outer cover 3 is provided with a first latching strip 31 that inserts into each of the strip-shaped latches 43. Preferably, there are four strip-shaped latches 43, symmetrically arranged in pairs on the upper end of the inner cover 4. A second horizontal latching strip 44 is provided on the outer side of the lower end of the inner cover 4, and a second horizontal latching groove 32 is provided on the inner wall of the outer cover 3 to engage with the second latching strip 44. The structure is positioned by the engagement of the first latching strip 31 of the outer cover 3 with the corresponding strip-shaped latch 43 of the inner cover 4, and the inner cover 4 and the outer cover 3 are fixedly connected by the engagement of the second latching strip 44 of the inner cover 4 with the second horizontal latching groove 32 of the outer cover 3. A logo is printed on the outer cover 3.

[0025] like Figure 2 , Figure 5 and Figure 7 As shown, the shoulder sleeve 2 is attached to the outside of the boss 11. Multiple reinforcing blocks 13 are provided on the shoulder to abut against the shoulder sleeve 2. During the process of pressing the shoulder sleeve 2 into the bottle body 1, the shoulder can be prevented from collapsing and will not affect the installation of the shoulder sleeve 2.

[0026] The shoulder sleeve 2 has an outer ring 21 that abuts against the upper edge of the bottle body 1 and an inner ring 22 that abuts against the shoulder. The inner ring 22 has grooves 221 for the insertion of each reinforcing block 13. A ring groove 111 is formed along the periphery of the side wall of the boss 11. A protrusion 222 that engages with the ring groove 111 is provided on the side wall of the inner ring 22. Symmetrically arranged breaks 223 divide the protrusion 222 into two segments. Multiple reinforcing ribs 23 are evenly arranged on the shoulder sleeve 2 at positions corresponding to the outer ring 21 and the inner ring 22. The top surface of each reinforcing block 13 is a clearance slope, and the bottom surface of each reinforcing rib 23 is also a clearance slope to avoid structural conflicts between the reinforcing blocks 13 and the reinforcing ribs 23. The reinforcing ribs 23 effectively reduce warping deformation of the shoulder sleeve 2, resulting in a more evenly distributed gap between the shoulder sleeve 2 and the boss 11 of the bottle body 1, making it more aesthetically pleasing.

[0027] The shoulder sleeve 2 is installed together with the bottle body 1 by engaging the protrusion 222 of the shoulder sleeve 2 with the annular groove 111 of the boss 11. Since the protrusion 222 is broken and not a complete circle, it is easier for the shoulder sleeve 2 to be pressed into the bottle body 1, and the weld line is less likely to break, thus reducing the defect rate.

[0028] Specifically, the cross-section of the bottle body 1 is an ellipse that is narrow at both ends and wide in the middle, and the shape of the shoulder sleeve 2 matches the cross-sectional shape of the bottle body 1. The shape of the bottle cap also matches the cross-sectional shape of the bottle body 1. Each break 223 is respectively set at both ends of the shoulder sleeve 2 in the short axis direction. With this arrangement, when the shoulder sleeve 2 is pressed into the shoulder of the bottle body 1, the two ends of each protrusion 222 first fall on the shoulder of the bottle body 1, forming a stable support point, preventing left and right swaying, and facilitating assembly.

[0029] Limiting protrusions 14 are provided at both ends of the shoulder of the bottle body 1 along the long axis. The limiting protrusions 14 are located between the outer ring 21 and the inner ring 22 of the shoulder sleeve 2 to ensure that the shoulder sleeve 2 will not sway left and right.

[0030] Furthermore, such as Figure 2 as well as Figures 6-8 As shown, the dispensing head 12 is provided with a dispensing port, and an inner plug 5 is fitted inside the dispensing head 12. One end of the inner plug 5 is the inlet end, and the other end of the inner plug 5 is a conical dispensing end. A dispensing channel 51 is opened inside the inner plug 5. Due to the small structure of the inner plug 5, the dispensing channel 51 is relatively long and thin. The dispensing end of the inner plug 5 extends out of the dispensing port and is fitted with the dispensing port. The threaded hole 41 of the inner cover 4 has space to accommodate the dispensing end of the inner plug 5. Multiple protrusions 52 are provided on the end face of the inlet end of the inner plug 5. Stainless steel balls 6 are provided inside the bottle body 1, which abut against each of the protrusions 52. A liquid inlet gap is formed between the stainless steel balls 6 and each protrusion 52. With this design, when the bottle 1 is turned upside down, the contents will flow out through the narrow liquid outlet channel 51 at a slow flow rate. The stainless steel ball 6 will fall on the protrusion 52 at the liquid inlet end of the inner stopper 5, so that the contents can only flow from the liquid inlet gap into the liquid outlet channel 51, thus avoiding a large amount of contents flowing out.

[0031] Furthermore, such as Figure 3 and Figure 7 As shown, the inner cover 4 is provided with an inner sealing post 45 and an outer sealing ring 46 at the top of the threaded hole 41. The inner sealing post 45 is inserted into the liquid outlet end of the inner plug 5 and makes sealing contact with the liquid outlet end. The outer sealing ring 46 is sealed and sleeved on the outside of the liquid outlet end of the inner plug 5. With this configuration, the inner plug 5 and the inner cover 4 adopt a double seal, which provides a better sealing effect. In addition, the outer sealing ring 46 also has a guiding function. When the inner sealing post 45 of the inner cover 4 is about to rotate and insert into the liquid outlet end of the inner plug 5, if it becomes misaligned, the outer sealing ring 46 can play a guiding role to prevent the inner sealing post 45 from crushing the liquid outlet end of the inner plug 5.

[0032] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
