Description

Technical Field

[0001] This utility model relates to the field of packaging bottle technology, specifically to a packaging bottle that is easy to open. Background Technology

[0002] Among existing packaging technologies, threaded-seal bottles are widely used due to their advantages such as good sealing performance and low cost. However, traditional threaded-seal bottles have several inconveniences in practical use: Firstly, to ensure a tight seal, the main cap and bottle body are tightly fitted together, and a sealing ring is connected to the bottom of the main cap, requiring a large torque to open. This makes them difficult for the elderly, children, or people with weak hand strength. Secondly, some bottle caps lack sufficient anti-slip design, making them prone to slipping when opening, further increasing the difficulty of opening. Although some existing technologies use anti-slip textured cap designs, most are single-texture structures with limited anti-slip effect and lack effort-saving mechanisms to assist in opening. Utility Model Content

[0003] The purpose of this invention is to provide a packaging bottle that is easy to open, making it convenient for the elderly, children, or people with weak hand strength to use.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An easy-to-open packaging bottle includes a bottle body, a main cap that is threadedly sealed to the bottle body, and a secondary cap that is fitted over the main cap. The inner wall of the secondary cap has a first anti-slip texture, and the outer wall of the main cap has a second anti-slip texture. By rotating the secondary cap, the first and second anti-slip textures engage tightly, assisting in unscrewing the main cap.

[0005] Preferably, the first anti-slip pattern is a vertical stripe arranged circumferentially on the inner wall of the secondary bottle cap, and the second anti-slip pattern is a vertical stripe arranged circumferentially on the outer wall of the main bottle cap; and the interval between the first anti-slip patterns is greater than the interval between the second anti-slip patterns.

[0006] Preferably, the secondary bottle cap includes an inner secondary bottle cap and an outer secondary bottle cap nested together. The inner diameter of the inner secondary bottle cap matches the outer diameter of the main bottle cap, and the first anti-slip texture is provided on the inner wall of the inner secondary bottle cap, so that when the secondary bottle cap is fitted around the main bottle cap, the first anti-slip texture and the second anti-slip texture can engage.

[0007] Preferably, a guide slope is provided along the bottom circumference of the inner sub-cap, and the guide slope is inclined from the inner wall of the inner sub-cap to the outer wall.

[0008] Preferably, the top of the inner sub-cap is fixed at the middle position inside the outer sub-cap, and when the inner sub-cap is sleeved on the main cap and engages with the main cap, the bottom of the outer sub-cap is in contact with the bottle body.

[0009] Preferably, the bottom of the bottle body is concave to form a recess, and the bottle body includes a cylindrical bottle body and a bottle mouth. The bottle body and the bottle mouth are connected by a funnel-shaped inclined surface. The small diameter end of the funnel-shaped inclined surface is connected to the bottle mouth, and the large diameter end is connected to the bottle body.

[0010] Preferably, an anti-theft ring is connected to the lower end of the main bottle cap.

[0011] In the above technical solution, by setting a secondary cap, which includes an inner secondary cap and an outer secondary cap, the first anti-slip texture on the inner wall of the inner secondary cap tightly engages with the second anti-slip texture on the outer wall of the main cap, increasing the friction between them and preventing relative sliding between the main cap and the secondary cap. When opening the bottle using the secondary cap, the user's point of force is on the outer wall of the outer secondary cap, increasing the lever arm compared to directly rotating the main cap. According to the torque formula, with a constant friction, an increased lever arm reduces the force required to open the cap. The anti-slip texture design allows the friction and the change in lever arm to work synergistically, reducing the force required to open the bottle, making the opening process easy and effortless, and meeting the needs of children, the elderly, and people with hand injuries or other individuals with limited hand strength.

[0012] By setting a guide slope around the bottom of the inner sub-cap, which slopes from the inner wall to the outer wall, the sub-cap can guide the inner sub-cap when it is fitted onto the main cap, thus improving the ease of operation.

[0013] The inner secondary cap is interference-fitted with the main cap. After opening the bottle, the main cap is fixed inside the secondary cap by friction. Both can be removed and placed together for easy storage and to prevent the main cap from being lost. When carrying the bottle, there is no need to worry about the secondary cap falling off or becoming loose, thus improving the convenience of carrying it. Attached Figure Description

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings: like Figures 1 to 4 As shown, an easy-to-open packaging bottle includes a bottle body 1, a main cap 2, and a secondary cap 3. The bottle body 1, main cap 2, and secondary cap 3 are all injection molded from food-grade PET material, ensuring both safety and structural strength. The bottle body 1 includes a cylindrical body 11 and a bottle neck. The body 11 and the bottle neck are connected by a funnel-shaped inclined surface 12. The smaller diameter end of the funnel-shaped inclined surface 12 connects to the bottle neck, and the larger diameter end connects to the bottle body 11, allowing the liquid inside the bottle body 1 to flow smoothly out along the inclined surface when poured, avoiding residue at the transition between the body 11 and the bottle neck.

[0017] The main cap 2 is connected to the bottle mouth of the bottle body 1 by threads for a sealing connection. A sealing ring is also connected to the lower end of the main cap to ensure the sealing performance of the packaging bottle and prevent liquid leakage from the bottle body 1. A second anti-slip texture 21 is provided on the outer wall of the main cap 2. The second anti-slip texture 21 consists of circumferentially arranged vertical stripes with a stripe height of 0.8 mm and a spacing of 1.2 mm. The design of the second anti-slip texture 21 increases the surface roughness of the main cap 2 and facilitates its mating with the auxiliary cap 3.

[0018] The secondary bottle cap 3 is fitted over the main bottle cap 2, comprising an inner secondary bottle cap 31 and an outer secondary bottle cap 32 nested together. The inner diameter of the inner secondary bottle cap 31 is interference-fitted with the outer diameter of the main bottle cap 2, so that after opening the bottle, the main bottle cap 2 is fixed inside the secondary bottle cap 3 by friction, allowing both to be removed and stored together for easy storage and to prevent the main bottle cap 2 from being lost. Simultaneously, when carrying the bottle, there is no need to worry about the secondary bottle cap 3 falling off or becoming loose, improving portability. The inner wall of the inner secondary bottle cap 31 has a first anti-slip texture 311, which consists of circumferentially arranged vertical stripes with a height of 0.8 mm and a spacing of 2.4 mm. The spacing of these stripes is greater than that of the second anti-slip texture 21. When the secondary bottle cap 3 is fitted over the main bottle cap 2, the first anti-slip texture 311 and the second anti-slip texture 21 can achieve a tight engagement, preventing slippage during rotation.

[0019] A guide slope 312 is provided along the circumference of the bottom of the inner sub-cap 31. The guide slope 312 slopes from the inner wall of the inner sub-cap 31 to the outer wall. This guide slope 312 plays a guiding role when fitting the sub-cap 3, allowing the inner sub-cap 31 to be quickly and accurately fitted onto the main cap 2, improving ease of operation. The top of the inner sub-cap 31 is fixed in the middle of the inner part of the outer sub-cap 32, forming a "T"-shaped internal support structure, which enhances the overall rigidity of the sub-cap 3. When the inner sub-cap 31 is fitted onto the main cap 2 and engages with it, the bottom of the outer sub-cap 32 contacts the bottle body 1. At this time, the outer sub-cap 32 not only provides a comfortable grip surface, but also, through the support of the bottle body 1, prevents the sub-cap 3 from axial displacement during rotation, further improving opening stability. When using the sub-cap 3 to open the packaging bottle, the user applies force to the outer wall of the outer sub-cap 32, increasing the lever arm length compared to directly rotating the main cap 2. According to the torque formula, with a constant frictional force, the lever arm increases, and the force required to open the main bottle cap 2 decreases. Even people with weaker hand strength, such as children, the elderly, and those with hand injuries, can easily open the main bottle cap 2.

[0020] The bottom of the bottle body 1 is recessed inward to form a recess 13. The recess 13 adopts a recessed structure similar to a five-petal flower. The recessed design can distribute the pressure inside the bottle to a larger surface area, reduce the pressure per unit area, not only improve the impact resistance of the bottle body 1 and avoid the bottle body from breaking due to pressure changes during transportation, but also enhance the stability of the bottle body when placed.

[0021] The usage process of this embodiment is as follows: When it is necessary to open the packaging bottle, align the inner sub-cap 31 of the sub-cap 3 with the main cap 2, and fit it onto the outside of the main cap 2 through the guide slope 312 until the bottom of the outer sub-cap 32 contacts the bottle body 1. At this time, the first anti-slip texture 311 and the second anti-slip texture 21 are tightly engaged. Hold the outer sub-cap 32 and rotate it clockwise. Using the increased torque of the sub-cap 3, the main cap 2 can be easily unscrewed. After opening, the main cap 2 is fixed inside the sub-cap 3 by friction. The main cap 2 and the sub-cap 3 can be removed as a whole and placed aside. Pour out the liquid in the bottle. After use, use the sub-cap 3 to screw the main cap 2 back onto the bottle mouth to seal it.

[0022] This embodiment is merely an illustration of the concept and implementation of this utility model, and is not intended to limit it. Under the concept of this utility model, the technical solution without substantial changes is still within the protection scope.
