Description

Technical Field

[0001] This utility model relates to a capacity display mechanism and a packaging bottle containing the mechanism. Background Technology

[0002] Existing lotions and creams all use vacuum pump packaging, and the bottles are mostly made of opaque materials. Consumers cannot know the remaining volume or the status of the cosmetic during use. Furthermore, consumers are unaware of the remaining product volume during use. If the pump stops dispensing, they don't know whether the product is empty or if there's a packaging malfunction causing the dispensing to stop. This lack of visual information about the product's status can lead to gaps in product availability or misunderstandings, resulting in complaints. Utility Model Content

[0003] The purpose of this utility model is to overcome the defects of the prior art and provide a capacity display mechanism with a remaining capacity indication function. When consumers use the product, they can understand the usage level and remaining capacity of the product by the color change of the display strip. After the pump stops discharging, they can also intuitively know whether the product has been used up. Or, when there is still a lot of capacity left, they can clearly and intuitively know that the packaging function is malfunctioning and causing the product to stop discharging. Consumers can intuitively understand the capacity status of the product.

[0004] Another objective of this invention is to provide a packaging bottle containing a capacity display mechanism.

[0005] One technical solution to achieve the above objective is: a capacity display mechanism, disposed between a piston and a bottom cap, wherein the piston is disposed inside the bottle body, and the bottom cap is fixed to the lower opening of the bottle body; the capacity display mechanism includes a fixing plug, a fixing seat, and two sets of display strip assemblies, wherein:

[0007] A mounting groove for a fixed seat that runs through the front and back is provided in the middle of the bottom cover;

[0008] The fixing base is snapped into the fixing base mounting groove. Two display color strip mounting positions are arranged one in front of the other in the fixing base. Each display color strip mounting position has a horizontally arranged hollow shaft mounting post. A display color strip through slot is provided between the two display color strip mounting positions.

[0009] The two sets of display strip components are respectively arranged in the two display strip mounting positions;

[0010] Each set of display strip assemblies includes a hollow shaft and a display strip. The hollow shaft is sleeved on the corresponding hollow shaft mounting post. The tail ends of the display strips of the two sets of display strip assemblies are respectively wound around the corresponding hollow shaft. The head ends are wound outward one by one through the front and rear sides of the fixing base and through the display strip through the slot before being connected to the buckle post of the fixing plug.

[0011] Each display strip has multiple color segments. When the piston moves upward, the display strip moves upward synchronously through the fixed plug. The hollow shaft rotates along the hollow shaft mounting column to release the display strip. The remaining amount of material in the bottle can be determined by observing the colors of the display strips on the front and rear sides of the fixed seat.

[0012] In one of the aforementioned capacity display mechanisms, the length of the released display strip is equal to the height of the upward movement of the piston.

[0013] In the aforementioned capacity display mechanism, observation windows are respectively provided on the front and rear sides of the bottle body, and the two observation windows are arranged one-to-one with the front and rear sides of the fixed base, through which the color of the display strip is observed.

[0014] In the aforementioned capacity display mechanism, a piston latch is provided at the lower end of the piston, and a fixed plug latch adapted to the piston latch is provided in the upper opening of the fixed plug, wherein the piston latch and the fixed plug latch are engaged.

[0015] In the aforementioned capacity display mechanism, a fixing seat buckle is provided on the left and right sides of the bottom end of the fixing seat, and each fixing seat buckle has an outwardly protruding fixing seat stop. A bottom cover buckle is provided on the left and right sides of the fixing seat mounting groove, and each bottom cover buckle has a stop groove that matches the fixing seat stop. The fixing seat buckle and the bottom cover buckle are engaged, and the fixing seat stop is engaged in the stop groove.

[0016] In the aforementioned capacity display mechanism, the head end of the display strip is provided with a fastening post connection hole, and the fastening post connection holes of the two sets of display strip assemblies are all fitted onto the fastening post and fixed by a fixing piece.

[0017] In the aforementioned capacity display mechanism, the display strip has three color segments from beginning to end: a green segment, a yellow segment, and a red segment. When the material utilization rate is 0-50%, the green segment is displayed; when the material utilization rate is 50%-90%, the yellow segment is displayed; and when the material utilization rate is 90%-100%, the red segment is displayed.

[0018] This utility model also provides a packaging bottle for displaying capacity, which includes the above-mentioned capacity display mechanism.

[0019] In the aforementioned packaging bottle for displaying capacity, a pump core assembly is provided at the bottle mouth via a shoulder sleeve, a push cap is provided at the upper end of the pump core assembly, and a cover is provided on the outside of the push cap.

[0020] The present invention relates to a capacity display mechanism and a packaging bottle containing the mechanism, which has a remaining capacity indication function. When consumers use the product, they can understand the usage level and remaining capacity of the product by the color change of the display band. After the pump stops dispensing material, they can also intuitively know whether the product has been used up.

[0042] To enable those skilled in the art to better understand the technical solution of this utility model, its specific embodiments will be described in detail below with reference to the accompanying drawings.

[0043] Please see Figures 1 to 3 A capacity-displaying packaging bottle includes a bottle body 5, a pump core assembly 3, a push cap 2, and a cover 1. A bottom cover 11 is provided at the lower opening of the bottle body 5. A piston 6 is disposed inside the bottle body 5, and a capacity display mechanism is disposed between the bottom cover 11 and the piston 6. The pump core assembly 3 is mounted at the bottle mouth of the bottle body 5 via a shoulder sleeve 4. The push cap 2 is located at the upper end of the pump core assembly 3, and the cover 1 covers the outside of the push cap 2.

[0044] In this vacuum pump-structured packaging bottle, after opening the cover 1 and pressing the button 2, the pump core assembly 3 moves downward, drawing out the material. The material is then ejected from the nozzle of the button 2 through the channel. With continued use, the material is expelled from the bottle body 5. Due to the principle of atmospheric pressure balance, the space inside the bottle body 5 decreases, creating a negative pressure. Atmospheric pressure then pushes the piston 6 upward to achieve atmospheric pressure balance. As the material is continuously used, the air pressure inside the bottle body 5 decreases, causing the piston 6 to move upward repeatedly. The working principle of this invention utilizes this upward movement of the piston 6.

[0045] Please see Figures 4 to 21 The capacity display mechanism includes a fixed plug 7, a fixed base 10, and two sets of display strip assemblies 9.

[0046] The upper opening of the retaining plug 7 is engaged with the lower end of the piston 6. Specifically, the lower end of the piston 6 is provided with a piston latch 61 (see...). Figure 7The upper opening of the retaining plug 7 is provided with a retaining plug latch 71 that is compatible with the piston latch 61 (see...). Figure 8 The upper opening of the fixed plug 7 is fitted onto the lower end of the piston 6, and the piston buckle 61 is engaged with the fixed plug buckle 71.

[0047] A retaining post 72 is longitudinally provided at the lower end of the fixing plug 7.

[0048] A through-hole mounting groove 111 is provided in the middle of the bottom cover 11. The fixing seat 10 is snapped into the mounting groove 111. Specifically, fixing seat buckles 101 are provided on the left and right sides of the bottom end of the fixing seat 10. Each fixing seat buckle 101 has an outwardly protruding fixing seat stop 102. Bottom cover buckles 112 are provided on the left and right sides of the mounting groove 111. Each bottom cover buckle 112 has a stop groove 113 that matches the fixing seat stop 102. The fixing seat 10 is set in the mounting groove 111, and the fixing seat buckles 101 and the bottom cover buckles 112 are snapped into each other to restrict the left and right movement of the fixing seat 10. The fixing seat stop 102 is snapped into the stop groove 113 to restrict the front and back movement of the fixing seat 10.

[0049] The mounting base 10 has two display ribbon mounting positions arranged one in front of the other. Each display ribbon mounting position has a horizontally arranged hollow shaft mounting post 103, and a display ribbon through slot 104 is provided between the two display ribbon mounting positions.

[0050] Two sets of display strip assemblies 9 are arranged one-to-one in two display strip mounting positions. Each set of display strip assemblies 9 includes a hollow shaft 91 and a display strip 93. The hollow shaft 91 is sleeved on the corresponding hollow shaft mounting post 103. The tail ends of the display strips 91 of the two sets of display strip assemblies are respectively wound around the corresponding hollow shaft 91. The head ends are respectively wound outward through the front and rear sides of the fixing seat 10 and through the display strip through slot 104, and then connected to the buckle post 72 of the fixing plug 7. Specifically, the head end of the display strip 91 is provided with a buckle post connecting hole 92. The buckle post connecting holes 92 of the two sets of display strip assemblies are all sleeved on the buckle post 72 and fixed by the fixing piece 8.

[0051] Each display band 93 has multiple color segments.

[0052] As the contents of bottle 5 are gradually used, the air pressure inside bottle 5 decreases, causing piston 6 to move upward. Since the head of the display strip 93 in the display strip assembly 9 is fixed to piston 6 via the fixing plug 7; the display strip 93 is wound around the hollow shaft 91, and the hollow shaft 91 is fitted onto the hollow shaft mounting post 103, allowing the two sets of display strip assemblies 9 to cooperate with the fixing seat 10, and the fixing seat 10 and bottom cover 11 are fixed by snap-fit; when piston 6 moves upward, the fixing plug 7 drives the display strip to move upward synchronously, and the hollow shaft 91 rotates along the hollow shaft mounting post 103, releasing the display strip 93, allowing it to be smoothly moved upward by piston 6. The length of the released display strip 93 is equal to the height of piston 6's upward movement. By observing the color of the display strip 93 on the front and rear sides of the fixing seat 10, the remaining contents of bottle 5 can be determined.

[0053] Further, please refer to Figure 21 An observation window 51 is provided on the front and rear sides of the bottle body 5. The two observation windows 51 are set one-to-one with the front and rear sides of the fixed base 10. The color of the display color strip 93 can be observed through the observation window 51.

[0054] In this embodiment, the display band 93 has three color segments from beginning to end: green, yellow, and red. When the material utilization rate is 0-50%, the green segment is displayed; when the material utilization rate is 50%-90%, the yellow segment is displayed; and when the material utilization rate is 90%-100%, the red segment is displayed.

[0055] The number of turns of the display ribbon 93 on the hollow shaft 91 is determined by the following steps:

[0056] S1, First, analyze the length of each turn of the display ribbon wound on the hollow shaft 91:

[0057] Define the thickness of the single-layer display ribbon 93 as T. When the display ribbon 93 is wound around the hollow shaft 91, the radius r1 of the first turn is approximately equal to the radius r of the hollow shaft, and the circumference of the first turn is C1 = 2πr1 = 2πr.

[0058] The radius of the second ring is r2 = r + T, and its circumference is C2 = 2πr2 = 2π(r + T);

[0059] The radius of the third ring is r3 = r + 2T, and its circumference is C3 = 2πr3 = 2π(r + 2T);

[0060] And so on, the radius r of the nth circle n = r + (n-1)T, its perimeter C n =2πr n =2π[r+(n-1)T];

[0061] S2, then calculate the total length S of the n turns of the ribbon.n :S n It is the sum of the first n terms of an arithmetic sequence with first term a1 = 2πr and common difference d = 2πT;

[0062] According to the formula for the sum of the first n terms of an arithmetic sequence:

[0063]

[0064] Substituting a1 = 2πr and d = 2πT into equation (1), we get:

[0065]

[0066] Simplify equation (2) to get S n =2πrn+πTn(n-1)=πn[2r+(n-1)T];

[0067] S3, Next, establish an equation based on the set conditions: Set the rising height of piston 6 to H, the pre-pulled length of the display ribbon to A, and the total length of the display ribbon L = H + A;

[0068] Let L = S n That is, H+A=πn[2r+(n-1)T];

[0069] Expanding, we get: H + A = πn(2r + nT - T) = π(2r - T)n + πTn 2 (3);

[0070] Rearranging equation (3) into a quadratic equation in n:

[0071] πTn 2 +π(2r - T)n-(H + A)=0 (4);

[0072] S4. Finally, solve the quadratic equation in one variable: ax 2 The formula for finding the quadratic expression for +bx+c=0 is:

[0073]

[0074] Let a = πT, b = π(2r-T), c = -(H+A), x = n; then the quadratic formula of equation (4) is:

[0075]

[0076] If the number of cycles n>0, then:

[0077]

[0078] Equation (5) is the formula for calculating the number of turns of the display ribbon on the hollow shaft. By calculating the number of turns of the display ribbon on the hollow shaft using Equation (5), the material utilization rate can be determined based on the piston rising height, and then the required length of each color segment of the display ribbon can be determined.

[0079] In summary, the capacity display mechanism and the packaging bottle containing the mechanism of this utility model have a remaining capacity indication function. When consumers use the product, they can understand the usage level and remaining capacity of the product by the color change of the display band. After the pump stops dispensing, they can also intuitively know whether the product has been used up. Or, when there is still a lot of capacity left, they can clearly and intuitively know that there is a problem with the packaging function that is causing the dispensing. Consumers can intuitively understand the capacity status of the product.
