Description

Technical Field

[0001] This utility model belongs to the field of beverage packaging, specifically relating to a solid-liquid separation beverage bottle cap assembly that produces no debris. Background Technology

[0002] Currently, there are many solid-liquid separation beverage bottle caps on the market, which are composed of multiple parts. The working principle is to set a receiving cavity inside the bottle cap to hold a predetermined beverage solution, and to set an opening on the receiving cavity that corresponds to the mouth of the beverage bottle. The opening is sealed with an aluminum film or a plastic sheet. A blade structure is set on another part near the opening. When in use, it is driven by human power to make the parts move relative to each other, so that the blade structure cuts through the aluminum film or tears the plastic sheet in a predetermined manner, allowing the predetermined beverage solution to flow from the receiving cavity into the beverage bottle.

[0003] It is evident that current products of this type are made by cutting aluminum foil or tearing plastic sheets. However, this type of product is prone to producing aluminum foil and plastic fragments during the cutting or tearing process, which can mix into the beverage and potentially cause discomfort to the user. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a solid-liquid separation beverage bottle cap assembly that generates no debris. While ensuring solid-liquid separation, it does not cut the aluminum film or tear the plastic sheet during use, thus preventing the generation of aluminum film or plastic debris and avoiding user discomfort caused by debris falling in.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A dust-free solid-liquid separation beverage bottle cap assembly is disposed on a predetermined bottle opening, the predetermined bottle opening having a capping direction. The assembly includes an upper cap, a lower cap, and an inner cap sequentially coupled along the capping direction. The upper cap has an upper cap surface and a receiving skirt formed on the inner surface of the upper cap surface. The lower cap has a receiving section tightly coupled to the receiving skirt. The coupled receiving skirt and receiving section form a composite receiving cavity. The composite receiving cavity has a discharge port facing the predetermined bottle opening along the capping direction. The inner cap is tightly coupled to the discharge port. The upper cover has a passive opening and closing door that can open and close the material discharge chamber. The upper cover has an active push rod formed on the inner surface of the upper cover surface, located inside the receiving skirt and extending toward the passive opening and closing door in the closing direction. The passive opening and closing door has a lifting area and a closing area toward the upper cover surface. The distance between the lifting area and the upper cover surface is used as the ejection interval, and the distance between the closing area and the upper cover surface is used as the closing interval. The extension length of the active push rod is less than the closing interval and greater than the ejection interval.

[0006] Preferably, the upper and lower caps have overlapping opening rotation axes extending along the closing direction. The lower cap can rotate relative to the predetermined bottle opening via the opening rotation axis, and the upper cap can rotate relative to the lower cap via the opening rotation axis. The lifting area and the closing area are distributed along the circumferential direction of the lower cap's rotation. Furthermore, the lifting area is parallel to the inner surface of the top cover, and the passive opening and closing door panel forms a closing groove, with the bottom surface of the closing groove forming a closing area.

[0007] Preferably, the receiving cylindrical section is a continuously closed sheet extending along the closing direction. One end of the receiving cylindrical section forms a thin-walled edge, and the circumferential surface of the thin-walled edge forms a continuously closed first anti-slip stripe. The thin-walled edge forms a material discharge cavity. The inner cover includes an inner cover base and a passively opening and closing door. The inner cover base forms a material discharge channel extending along the closing direction and a continuously closed engaging groove surrounding the material discharge channel. The material discharge channel is located inside the material discharge cavity. The inner sidewall of the engaging groove has a second anti-slip stripe. The thin-walled edge is inserted into the engaging groove, and the first and second anti-slip stripes are in frictional contact. The passively opening and closing door has a snap-in boss and a door panel surrounding the snap-in boss. The snap-in boss is inserted into the material discharge channel, and the door panel surrounding the inner cover base is hinged.

[0008] Preferably, the upper cover also has an upper cover skirt, the inner wall of which has a guide flange, and the lower cover has a mating skirt and a lower cover skirt. The mating skirt extends into the upper cover skirt, and the outer peripheral surface of the mating skirt has an anti-detachment flange. The anti-detachment flange is closer to the predetermined bottle opening than the guide flange, and the guide flange and the anti-detachment flange interfere with each other in the closing direction. The lower cover skirt is sleeved outside the predetermined bottle opening and is threadedly connected. Furthermore, the anti-detachment flange has an assembly notch extending in the same direction, and the extension length of the assembly notch is greater than or equal to the extension length of the guide flange. The assembly notch and the guide flange interfere with each other in the covering direction and form an interference step difference smaller than that of the other anti-detachment flanges.

[0009] Furthermore, the end face of the anti-slip flange facing the top cover is a wedge-shaped surface that is inclined outward.

[0010] Furthermore, the outer peripheral surface of the mating skirt also has protruding circumferential vertical ribs. The protrusion height of the circumferential vertical ribs relative to the outer peripheral surface of the mating skirt is greater than the maximum gap between the protruding end face of the guide flange and the outer peripheral surface of the mating skirt.

[0011] Furthermore, the circumferential vertical rib also has an assembly guide surface. One end of the assembly guide surface is located near the free end face of the mating cover skirt, and the other end is located between the anti-detachment flange and the lower cover skirt. The assembly guide surface passes through the assembly notch.

[0012] Furthermore, the assembly guide surface extends along the cover direction and is perpendicular to the plane of the anti-detachment flange. The circumferential vertical rib has only one protrusion height relative to the outer circumferential surface of the cover skirt, and the circumferential vertical rib also has a rotation-resistant linkage surface opposite to the assembly guide surface. Compared with the prior art, the beneficial effects of this utility model are: 1. Because the debris-free solid-liquid separation beverage bottle cap assembly of this utility model includes an upper cap, a lower cap, and an inner cap coupled sequentially along the capping direction, the upper cap has an upper cap surface and a receiving skirt, the lower cap has a receiving section that is tightly coupled with the receiving skirt, the receiving skirt and the receiving section form a composite receiving cavity, the composite receiving cavity has a discharge cavity opening facing a predetermined bottle opening, the inner cap is tightly coupled to the discharge cavity opening, and the inner cap has a passive opening and closing door that can open and close the discharge cavity opening, the upper cap has an active push rod extending toward the passive opening and closing door, the passive opening and closing door has a lifting area and a closing area, correspondingly forming an ejection interval and a closing interval, the extension length of the active push rod is less than the closing interval, and the extension length of the active push rod is greater than the ejection interval, therefore, this utility model, while ensuring solid-liquid separation, will not cut the aluminum film or tear the plastic sheet during use, thus avoiding the generation of aluminum film debris or plastic debris, and preventing user discomfort caused by debris falling in.

[0013] 2. Because the lifting area of ​​this utility model is parallel to the inner surface of the upper cover, and the passive opening and closing door has a closing groove, and the bottom surface of the closing groove forms a closing area, this utility model forms two areas at different distances on the inner surface of the upper cover by forming a groove on the passive opening and closing door. Thus, when the active push rod is in the closing direction and is in the closing area, that is, when the active push rod is inserted into the closing groove, the passive opening and closing door keeps the discharge chamber closed because the active push rod does not interfere with the passive opening and closing door. When the active push rod is in the closing direction and is in the lifting area, that is, when the active push rod interferes with the passive opening and closing door, the passive opening and closing door is opened, so that the composite receiving cavity communicates with the predetermined bottle opening through the discharge chamber, thereby allowing the predetermined beverage concentrate to flow from the composite receiving cavity into the predetermined bottle opening.

[0014] 3. Because the upper cover of this utility model also has an upper cover skirt, the inner wall of the upper cover skirt has a guide flange, the lower cover has a mating cover skirt and a lower cover skirt, the mating cover skirt extends into the upper cover skirt, and the outer peripheral surface of the mating cover skirt has an anti-detachment flange, the anti-detachment flange is closer to the predetermined bottle opening than the guide flange, and the guide flange and the anti-detachment flange interfere with each other in the closing direction, the lower cover skirt is sleeved outside the predetermined bottle opening and is threadedly connected, therefore, this utility model can allow the upper cover and the lower cover to rotate relative to each other on the same axis, without producing relative movement in the closing direction.

[0015] 4. Because the anti-detachment flange of this utility model has an assembly notch extending in the same direction, and the extension length of the assembly notch is greater than or equal to the extension length of the guide flange, the assembly notch and the guide flange interfere with each other in the closing direction and form a smaller interference step difference than other anti-detachment flanges. Therefore, in the assembly process of the upper and lower covers during the production process of this utility model, it is only necessary to align the guide flange with the assembly notch in the closing direction, and then apply pressure to the upper cover from the outside. The guide flange can then cross the assembly notch through a small elastic deformation to complete the assembly of the upper and lower covers.

[0016] 5. Because the end face of the anti-detachment flange facing the upper cover surface of this utility model is a wedge-shaped surface that is inclined outward, the external pressure required is smaller when the guide flange can cross the assembly gap through a small elastic deformation during the assembly process of the upper and lower covers in the production process.

[0017] 6. Because the outer peripheral surface of the mating cover skirt of this utility model also has protruding circumferential vertical ribs, and the protrusion height of the circumferential vertical ribs relative to the outer peripheral surface of the mating cover skirt is greater than the maximum gap between the protruding end face of the guide flange and the outer peripheral surface of the mating cover skirt, after the active push rod switches from the corresponding closed area to the corresponding lifting area and opens the passive opening and closing door, the upper cover can drive the lower cover to rotate by interfering with the circumferential vertical ribs in the rotation direction, thereby removing this utility model from the predetermined bottle opening.

[0018] 7. Because the circumferential vertical rib of this utility model also has an assembly guide surface, one end of the assembly guide surface is located near the free end face of the mating cover skirt, and the other end is located between the anti-detachment flange and the lower cover skirt. Furthermore, the assembly guide surface passes through the assembly notch. Therefore, in the assembly process of the upper and lower covers during the production process of this utility model, it is only necessary to press the guide flange against the assembly guide surface to conveniently make the guide flange correspond to the assembly notch on the closing side.

Detailed Implementation

[0031] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following embodiments, in conjunction with the accompanying drawings, specifically illustrate the dust-free solid-liquid separation beverage bottle cap assembly of this utility model. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0032] In this embodiment, the non-debris-generating solid-liquid separation beverage bottle cap assembly 100 is fitted onto a predetermined bottle opening (not shown in the accompanying drawings), and the predetermined bottle opening has a fitting direction D. like Figures 1 to 4 As shown, the chip-free solid-liquid separation beverage bottle cap assembly 100 includes an upper cap 10, a lower cap 20, and an inner cap 30 sequentially coupled along the capping direction D.

[0033] like Figure 5 As shown, the upper cover 10 has an upper cover surface 11 and an upper cover skirt 12. Specifically, the upper cover surface 11 is a plane.

[0034] The inner surface of the top cover 11 is formed with an upper sealing skirt 13, a receiving tube skirt 14, and an active push rod 16.

[0035] The upper cover skirt 13 and the receiving tube skirt 14 are arranged concentrically. The upper cover skirt 13 surrounds the outside of the receiving tube skirt 14, and both the upper cover skirt 13 and the receiving tube skirt 14 are continuously closed. The active push rod 16 is located inside the receiving tube skirt 14 and extends towards the lower cover 20 along the closing direction D. Specifically, both the upper cover skirt 13 and the receiving tube skirt 14 are circular. The free end of the active push rod 16 extends into the lower cover 20. The upper cover skirt 13 is elastic. In this embodiment, the outline of the free end of the active push rod 16 has a straight outline segment 161 parallel to the upper cover surface 11 and an inclined outline segment 162 inclined towards the upper cover surface 11.

[0036] The inner wall of the upper cover skirt 12 has an inwardly protruding guide flange 15, specifically, the guide flange 15 is located near the lower edge of the upper cover skirt 12.

[0037] like Figures 6 to 9 As shown, the lower cover 20 has a matching cover skirt 21, a lower cover skirt 22, and a receiving cylindrical section 23.

[0038] The upper cover 10 and the lower cover 20 have overlapping opening rotation axes (not shown in the figure) extending in the closing direction D. The lower cover 20 can rotate relative to the predetermined bottle opening via the opening rotation axis, and the upper cover 10 can rotate relative to the lower cover 20 via the opening rotation axis.

[0039] The lower cap skirt 22 is fitted onto the outside of the predetermined bottle opening and is threadedly connected by the capping thread 221 on its inner wall. Specifically, both the mating skirt 21 and the lower cap skirt 22 extend along the capping direction D and form a concentric, continuously closed circle. The mating skirt 21 extends into the upper cap skirt 12, and the upper cap skirt 13 is inserted into the inner wall of the free end of the mating skirt 21, forming a tight coupling.

[0040] The lower cap skirt 22 is fitted onto the predetermined bottle opening. The nominal size of the mating cap skirt 21 is smaller than that of the lower cap skirt 22, thereby forming a continuous and closed lower cap step surface 22A that is perpendicular to the lower cap skirt 22 between the mating cap skirt 21 and the lower cap skirt 22.

[0041] The outer periphery of the cover skirt 21 has an anti-slip flange 211 and a periphery vertical rib 212.

[0042] The anti-detachment flange 211 is closer to the predetermined bottle opening than the guide flange 15, and the guide flange 15 and the anti-detachment flange 211 interfere with each other in the closing direction D. Thus, when the upper cover 10 rotates relative to the lower cover 20, the anti-detachment flange 211 forms an obstruction and limit on the guide flange 15.

[0043] An assembly notch 211a extending in the same direction is formed on the anti-detachment flange 211, and the extension length of the assembly notch 211a is greater than or equal to the extension length of the guide flange 15. The assembly notch 211a and the guide flange 15 interfere with each other in the closing direction D, and the assembly notch 211a forms a smaller interference step difference than the anti-detachment flange 211 relative to the guide flange 15. The end face of the anti-detachment flange 211 facing the upper cover surface 11 is a wedge-shaped surface inclined outward. Specifically, the anti-detachment flange 211 is elastic. When the upper cover 10 is assembled to the lower cover 20, the guide flange 15 is aligned with the assembly notch 211a. By pushing the upper cover along the closing direction D, the guide flange 15 can push the assembly notch 211a, causing it to deform, so that the guide flange 15 passes over the assembly notch 211a, completing the assembly of the upper cover 10 and the lower cover 20.

[0044] Specifically, both ends of the guide flange 15 along the closing direction D are inclined surfaces, wherein the inclined surface near the predetermined bottle opening is used to facilitate the passage of the assembly notch 211a, and the inclined surface at the other end is used for convenient demolding.

[0045] The circumferential vertical rib 212 extends along the covering direction D and protrudes from the outer circumferential surface of the mating cover skirt 211. The circumferential vertical rib 212 has a relative assembly guide surface 212a and a rotation-resistant linkage surface 212b. Both the assembly guide surface 212a and the rotation-resistant linkage surface 212b extend along the covering direction D and are perpendicular to the plane containing the circular outline of the anti-detachment flange 211.

[0046] One end of the assembly guide surface 212a is located near the free end face of the mating cover skirt 21, and the other end is located between the anti-detachment flange 211 and the lower cover skirt 22. The assembly guide surface 212a passes through the assembly notch 211a. Specifically, the other end of the assembly guide surface 212a extends to the lower cover step surface 22A. When the upper cover 10 is assembled to the lower cover 20, the end of the guide flange 15 is pressed against the assembly guide surface 212a, and the guide flange 15 is moved down along the assembly guide surface 212a. This allows the guide flange 15 to easily pass over the assembly notch 211a, thus completing the assembly of the upper cover 10 and the lower cover 20.

[0047] The circumferential vertical rib 212 has only one protrusion height relative to the outer circumferential surface of the mating cover skirt 21. The protrusion height of the circumferential vertical rib 21 relative to the outer circumferential surface of the mating cover skirt 21 is greater than the maximum gap between the protruding end face of the guide flange 15 and the outer circumferential surface of the mating cover skirt 21. Therefore, when the upper cover 10 rotates relative to the lower cover 20, when it reaches the circumferential vertical rib 21, the circumferential vertical rib 21 interferes with the guide flange 15 through the rotation-blocking linkage surface 212b. Then, if the upper cover 10 continues to rotate, the upper cover 10 will no longer rotate relative to the lower cover 20, but will instead drive the lower cover 20 to rotate together.

[0048] The receiving cylindrical section 23 is formed inside the lower cover 20 and is a continuous closed sheet extending along the closing direction D. The receiving cylindrical section 23 is tightly coupled with the receiving skirt 14, thereby forming a composite receiving cavity 23A. One end of the receiving cylindrical section 23 is formed in the thin-walled edge 232 inside the lower cover skirt 22, and the peripheral surface of the thin-walled edge 232 is formed with a continuous closed first anti-slip stripe 232a. The thin-walled edge is formed with an open discharge cavity 23a that faces the predetermined bottle opening along the closing direction D. Specifically, the other end of the receiving cylindrical section 23 is formed in the elastic closed skirt 231 located inside the mating skirt 21, and the closed skirt 231 is tightly coupled with the lower edge of the receiving skirt 14. like Figure 10 and Figure 11 As shown, the inner cover 30 is tightly coupled to the discharge chamber opening 23a, and the inner cover 30 includes an inner cover base 31 and a passive opening and closing door 32. The passive opening and closing door 32 is opened and closed on the discharge chamber opening 23a. Specifically, the active push rod 16 extends toward the passive opening and closing door 32 along the closing direction D.

[0049] The inner cover base 31 has a material discharge channel 311 extending along the closing direction D and a continuously closed engagement groove 312 surrounding the material discharge channel. The material discharge channel 311 is located inside the material discharge cavity 23a. The inner sidewall of the engagement groove 312 has a second anti-slip stripe 312. When the thin wall end 232 is inserted into the engagement groove 312, the first anti-slip stripe 232a and the second anti-slip stripe 312 come into frictional contact, so that the coupled receiving cylinder section 23 and the inner cover 30 will not rotate relative to each other. Specifically, the material discharge channel 311 is a through hole corresponding to the material discharge cavity 23a, and the engagement groove 312 is continuously closed with the groove opening facing the predetermined bottle opening.

[0050] The passively opening and closing door panel 32 has a snap-in boss 321 and a door panel circumference 322 surrounding the snap-in boss 321. The snap-in boss 321 is engaged with the insertion channel 311. The door panel circumference 322 is connected to the inner cover base 31 by a hinged connection.

[0051] The passive opening and closing door panel 32 has a lifting area 321a and a closing area 321b facing the upper cover surface 11. The distance between the lifting area 321a and the upper cover surface 11 is used as the lifting interval, and the distance between the closing area 321b and the upper cover surface 11 is used as the closing interval. Thus, the lifting area 321a and the closing area 321b are distributed circumferentially along the rotation of the lower cover 20. Specifically, when the upper cover 10 is rotated relative to the lower cover 20, the active push rod 16 is selectively positioned to correspond to either the lifting area 321a or the closing area 321b.

[0052] The extension length of the active push rod 16 is less than the closing interval 321b, and the extension length of the active push rod 16 is greater than the ejection interval 321a. Specifically, most of the surface of the snap-in boss 321 is parallel to the top cover surface 11, and the surface of the snap-in boss 321 also has a closing groove 3211 recessed towards the predetermined bottle opening. The bottom of the closing groove 3211 has a portion parallel to the top cover surface 11. When the top cover 10 is rotated relative to the bottom cover 20, when the active push rod 16 corresponds to the closing area 321b, the active push rod 16 engages and enters the closing groove 3211. Therefore, the extension length of the active push rod 16 is less than the closing interval 321b; when the active push rod 16 corresponds to the lifting area 321a, the active push rod 16 interferes with the surface of the snap-in boss 321, so the extension length of the active push rod 16 is greater than the lifting interval 321b, and then the active push rod 16 pushes the snap-in boss 321 open relative to the door panel edge 322, and the discharge cavity 23a opens to the predetermined bottle mouth. In this embodiment, the bottom of the closed groove 3211 has a part corresponding to the straight contour section 161, and also a part corresponding to the inclined contour section 162 and transitioning to the outer plane of the groove.

[0053] In this embodiment, the outer peripheral surface of the upper cover skirt 12 also has upper cover anti-slip stripes 12a, and the outer peripheral surface of the lower cover skirt 22 also has lower cover anti-slip stripes 22a. The two annular anti-slip stripes each have an alignment mark (short ridge line). When the alignment mark is aligned along the closing direction, it indicates that the chip-free solid-liquid separation beverage bottle cap assembly 100 has not been activated.

[0054] The solid-liquid separation beverage bottle cap assembly 100, which generates no debris, is placed on the predetermined bottle opening. The upper cover 10 is rotated relative to the lower cover 20, and the active push rod 16 disengages from the closed area 321b to the lifting area 321a, thereby interfering with the surface of the snap-in boss 321. This causes the discharge chamber 23a to open towards the predetermined bottle opening, allowing the predetermined beverage contents in the composite receiving chamber 23A to fall into the predetermined bottle opening. Then, the upper cover 10 is rotated further. When the guide flange 15 interferes with the rotation-resistant linkage surface 212b of the circumferential vertical rib 212, the upper cover 10 will drive the lower cover 20 to rotate together, thereby causing the solid-liquid separation beverage bottle cap assembly 100 to detach from the predetermined bottle opening.

[0055] The above embodiments are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Various modifications or variations that can be made by those skilled in the art without creative effort within the scope of the appended claims are still within the scope of protection of this patent.
