Description

Technical Field

[0001] This utility model relates to the field of plastic products technology, and in particular to a compound packaging bottle. Background Technology

[0002] For products requiring the separation and storage of multiple components (such as concentrates and solvents) before use, existing integrated packaging often uses a puncture-to-mix release film. However, because the aluminum foil sealing layer is generally very thin and easily broken, the release film may accidentally rupture due to vibration during storage and transportation, leading to premature product failure. Therefore, there is an urgent need for a packaging solution that is easier to open, has a neat opening, and offers higher reliability against accidental opening. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a compound packaging bottle that can effectively prevent accidental opening during storage and transportation.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a composite packaging bottle, comprising a bottle body and a bottle cap, wherein the upper end of the bottle body has a bottleneck; characterized in that the bottle cap comprises an upper cap, an inner cylinder, an outer cylinder, and a lower cap; the lower cap is fixed to the lower part of the outer circumferential surface of the outer cylinder, and the inner sidewall of the lower cap is provided with an internal thread that mates with the outer thread of the bottle neck; the bottom end of the outer cylinder is provided with an aluminum foil sealing layer; the inner cylinder is vertically fixed to the middle position of the top of the upper cap, and the inner cylinder is inserted into the outer cylinder; the lower part of the outer cylinder... An easily breakable plate is fixed above the aluminum foil sealing layer. A continuous easily breakable groove is formed at the joint between the easily breakable plate and the inner wall of the outer cylinder, and the arc angle formed by the easily breakable groove is between 310° and 340°. The lower end face of the inner cylinder is inclined. Several limiting blocks are symmetrically fixed on the upper part of the outer circumference of the outer cylinder. An "L"-shaped limiting groove is formed on the side wall of the upper cover, corresponding to the limiting blocks one by one, and each limiting block is inserted into the corresponding limiting groove. The transverse section of the limiting groove is used to restrict the relative vertical movement of the upper cover and the outer cylinder.

[0005] Preferably, a plurality of downwardly extending baffles are symmetrically fixed at the bottom end of the top cover; a limiting ring is fixed at the middle of the outer circumference of the outer cylinder, and the limiting ring has notches that correspond one-to-one with each of the baffles; the side view projection of the baffle is an inverted trapezoid.

[0006] Preferably, the upper cover is provided with a limiting protrusion in each of the limiting grooves, and the limiting protrusion is located at the connection between the horizontal section and the vertical section of the limiting groove.

[0007] Preferably, the outer side of the top surface of each of the limiting blocks is inclined downwards, and the inner wall of the upper cover is provided with an installation groove adapted to the inclined surface below each of the limiting grooves.

[0008] Preferably, the lower inner diameter of the outer cylinder gradually decreases, and the lower part of the outer wall of the inner cylinder is provided with a protruding ring.

[0009] Compared with the prior art, this utility model has the following advantages:

[0010] 1. Prevention of Accidental Opening and Safe Transportation: In the initial state, the limiting block is engaged at the end of the transverse section of the "L"-shaped limiting groove and blocked by the limiting protrusion, preventing the top cover from being pressed down and maintaining a safe distance between the lower inclined surface of the inner cylinder and the fragile plate. This design effectively prevents the inner cylinder from accidentally opening the fragile plate due to transportation vibrations, ensuring the stability of the product during circulation. Simultaneously, the pre-set fragile groove does not form a complete closed loop, ensuring the structural strength of the fragile plate during storage and transportation, and providing reliable protection for the underlying aluminum foil sealing layer.

[0011] 2. Effortless opening and neat opening: The core innovation lies in using a "sloping pry-opening" mechanism instead of the traditional "spiked piercing" method. The fragile groove has been pre-damaged, reducing most of the fragile plate's circumference and retaining only a small connecting section. When the top cover is pressed down, the sloping surface at the lower end of the inner cylinder acts like a pry bar on the fragile plate. Utilizing the lever principle, a relatively small vertical force is required to neatly break it along the fragile groove and flip it downwards, forming a neat "hatch"-like opening. This method greatly reduces the opening effort and avoids the problems of fragmentation or irregular openings.

[0012] 3. Operation Guidance and Effort-Saving Optimization: The combined design of the inverted trapezoidal baffle and the notch of the limiting ring allows the baffle's inclined surface and the edge of the notch to interact during the pressing of the top cover, automatically guiding the top cover and inner cylinder to produce a slight rotation. This rotation allows the inclined surface of the inner cylinder to apply force more effectively and continuously to different positions of the fragile plate, thus completing the opening action more effortlessly and smoothly.

[0013] 4. Double sealing and convenient assembly: The convex ring at the bottom of the inner cylinder and the tapered inner wall of the outer cylinder form a tight fit, enhancing the sealing of the inner cylinder cavity and preventing the contents from being contaminated by moisture. The wedge-shaped top surface of the limiting block and the mounting groove design of the top cover make the assembly of the top cover and the outer cylinder more convenient and accurate.

[0020] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0021] like Figures 1 to 5 As shown, a compound packaging bottle includes a bottle body 1 and a bottle cap. The bottle body 1 has a neck 11 at its upper end. The bottle cap includes an upper cap 2, an inner cylinder 3, an outer cylinder 4, and a lower cap 5. The lower cap 5 is fixed to the lower part of the outer circumference of the outer cylinder 4, and the inner sidewall of the lower cap 5 is provided with an internal thread that mates with the outer thread of the neck 11. The bottom end of the outer cylinder 4 is provided with an aluminum foil sealing layer 6. The inner cylinder 3 is vertically fixed to the middle position of the top of the upper cap 2, and the inner cylinder 3 is inserted into the outer cylinder 4. A fragile plate 41 is fixed above the aluminum foil sealing layer 6 at the lower part of the outer cylinder 4. A continuous easy-break groove 42 is provided at the joint between the inner wall of the outer cylinder 4 and the inner cylinder 3, and the arc angle formed by the easy-break groove 42 is between 310° and 340°; the lower end face of the inner cylinder 3 is inclined; a number of limiting blocks 43 are symmetrically fixed on the upper part of the outer circumference of the outer cylinder 4; an "L"-shaped limiting groove 21 is provided on the side wall of the upper cover 2, which corresponds one-to-one with the limiting block 43, and each limiting block 43 is inserted into the corresponding limiting groove 21; the transverse section of the limiting groove 21 is used to restrict the relative up and down movement of the upper cover 2 and the outer cylinder 4.

[0022] Working principle: such as Figure 3 As shown, in the initial state, the bottle body 1 can be pre-filled with solvent (such as pure water). The sealed cavity formed by the inner cylinder 3 and the outer cylinder 4 contains solid or granular substances. The limiting block 43 is located at one end of the horizontal section of the "L"-shaped limiting groove 21. At this time, the top cover 2 cannot be pressed down. The lower end of the inner cylinder 3 maintains a safe distance from the fragile plate 41 to prevent the fragile plate from being pushed down due to transportation vibration, thereby breaking the aluminum foil sealing layer 6 and causing the material in the packaging bottle to become ineffective due to premature mixing.

[0023] When it is time to drink, the user can refer to the pattern on the top of the lid for operation. First, rotate the top lid 2. The rotation angle is determined by the length of the horizontal section of the "L"-shaped groove, so that each limiting block 43 slides relative to each limiting groove 21 and slides into the vertical section of the limiting groove 21. Finally, press down the top lid 2, so that the inner cylinder 3 moves downward and the bottom end of its lower inclined surface contacts the fragile plate 41 and applies pressure. Since the edge of the fragile plate 41 has been pre-cut by most of the way through the fragile groove 42, under the prying of the lower end of the inner cylinder, the fragile plate 41 breaks neatly along the fragile groove 42 and flips downward, thus breaking through the aluminum foil sealing layer 6 and forming a regular opening (such as...). Figure 4 As shown in the figure, the substance inside the cavity falls into the solvent in the bottle body 1 through the opening, and the user can complete the mixing and drinking after shaking the bottle body 1.

[0024] In this packaging bottle, since the aluminum foil sealing layer is generally very thin and easily broken, the easy-break plate effectively protects the aluminum foil sealing layer, thereby preventing it from breaking due to severe vibration during storage and transportation. At the same time, the pre-set easy-break groove allows it to be broken open without much force, thus protecting the aluminum foil sealing layer without affecting the user experience.

[0025] like Figure 1 , Figure 2 and Figure 5 As shown, the bottom end of the top cover 2 is symmetrically fixed with several downwardly extending baffles 22; a limiting ring 44 is fixed in the middle of the outer circumference of the outer cylinder 4, and the limiting ring 44 has notches 43 that correspond one-to-one with each baffle 22; the side view projection of the baffle 22 is an inverted trapezoid. In this packaging bottle, the vertical section of the limiting groove 21 is much wider than the horizontal section, so by slightly rotating the top cover 2, the limiting block 43 can enter the vertical section of the limiting groove 21. At this time, the lower end of the baffle 22 is also located above the notch 45. The side view projection of the baffle 22 is an inverted trapezoid, so the user only needs to continue to press down on the top cover 2. The cooperation between the inclined edge of each baffle 22 and the edge of the notch 45 generates a torque to guide the rotation, so that the top cover 2, along with the inner cylinder 3, rotates and presses down. The inclined surface at the lower end of the inner cylinder 3 can continuously switch positions to push the fragile plate downward, so that the part where the outer circumference of the fragile plate is loosely connected to the outer cylinder gradually breaks and breaks, thus making the operation more effortless.

[0026] like Figure 1 and Figure 2 As shown, each limiting groove 21 on the upper cover 2 is provided with a limiting protrusion 23. The protrusion 23 is located at the boundary between the horizontal and vertical sections of the limiting groove 21, and the presence of the protrusion 23 means that the slider must pass over it to slide from the horizontal section to the vertical section of the limiting groove 21, thereby effectively preventing the upper cover 2 from being accidentally touched and rotating.

[0027] like Figure 1 , Figure 2 and Figure 4As shown, the outer side of the top surface of each limiting block 43 is inclined downward, and an installation groove 24 adapted to each limiting block 43 is provided on the inner wall of the upper cover 2 below each limiting groove 21. Designing the limiting block 43 as a wedge shape and providing an installation groove 24 on the inner wall of the upper cover 2 makes the assembly of the cover more convenient.

[0028] like Figure 3 , Figure 4 and Figure 5 As shown, the lower inner diameter of the outer cylinder 4 gradually decreases, and a protruding ring 31 is provided on the lower part of the outer wall of the inner cylinder 3. The cooperation between the protruding ring 31 and the inner wall of the outer cylinder 4 can enhance the sealing of the cavity formed by the outer cylinder 4 and the inner cylinder 3, and can effectively prevent the material inside from being contaminated.

Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
