Description

Technical Field

[0001] This utility model relates to the field of packaging container technology, and more specifically, to a pressure-resistant carbonate bottle bottom structure. Background Technology

[0002] In existing technologies, carbonated bottle containers are typically used to store carbonated beverages, and their bottoms need to withstand significant internal pressure. However, traditional carbonated bottle bottom designs suffer from the following problems: insufficient structural strength, making them prone to bulging or cracking under high pressure, affecting the bottle's lifespan and safety; uneven material distribution at the bottom, leading to uneven stress distribution and further reducing the pressure resistance; and difficulty in balancing aesthetics and functionality, failing to meet market demands for high-quality packaging. Therefore, a carbonated bottle bottom structure is needed that can improve bottom strength, evenly distribute material, and also achieve an aesthetically pleasing design. Utility Model Content

[0003] The present invention provides a pressure-resistant carbonate bottle bottom structure that can alleviate the above-mentioned problems.

[0004] To alleviate the above problems, the technical solution adopted by this utility model is as follows:

[0005] A pressure-resistant carbonate bottle bottom structure includes a concave curved surface located at the center of the bottle bottom and a plurality of outwardly protruding claws evenly distributed circumferentially around the concave curved surface; the root of the outwardly protruding claws is connected to the edge of the concave curved surface by a transition arc with continuous curvature; the outwardly protruding claws gradually widen from the root to the top along the radial direction of the bottle bottom; the included angle formed by the projections of the opposite sides of two adjacent outwardly protruding claws onto a plane perpendicular to the axis of the bottle body is 55°~65°.

[0006] Preferably, the radius of curvature of the concave surface is 20~35mm.

[0007] Preferably, there are six protruding claws.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] 1) Through the combined design of concave curved surfaces and convex support claws, the bottle bottom can better distribute internal pressure. The concave curved surfaces provide support for the central area, while the convex support claws, through their geometry and distribution, evenly transmit pressure to all parts of the bottle bottom, thereby significantly improving the pressure resistance of the bottle bottom and reducing the risk of bulging or breakage.

[0010] 2) The design of the protruding claws makes the bottom mold material of the blow molding more evenly distributed. The protruding claws gradually widen from the root to the top along the radial direction of the bottom of the bottle. This gradient design ensures that the material is evenly distributed in all areas of the bottom of the bottle, avoiding the problem of local accumulation or weakness of the material, and further enhancing the overall strength of the bottom of the bottle.

[0011] 3) The geometric design of the convex claws and concave surface not only improves the structural strength of the bottle bottom, but also enhances its visual appeal. The uniform distribution and gradient design of the convex claws, as well as the smooth transition of the concave surface, make the bottle bottom look more refined and enhance the product's market competitiveness.

[0012] 4) The angle formed by the projection of the opposite sides of the outwardly protruding claws onto a plane perpendicular to the axis of the bottle body is 55°~65°. This angle design ensures the stability of the bottle bottom under different specifications and pressure conditions.

[0013] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, embodiments of this utility model are described below in detail with reference to the accompanying drawings. Attached Figure Description

[0014] To more clearly illustrate the technical solutions of the embodiments of this utility model, the drawings used in the embodiments will be briefly introduced below. It should be understood that the following drawings only show some embodiments of this utility model and should not be regarded as a limitation on the scope. For those skilled in the art, other related drawings can be obtained based on these drawings without creative effort.

[0015] Figure 1 This is a schematic diagram of the pressure-resistant carbonate bottle bottom structure described in the embodiment;

[0016] In the figure: 1-concave curved surface, 2-convex claw, 3-transition arc, 4-opposite side surface. Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0018] Please refer to Figure 1 This embodiment provides a pressure-resistant carbonate bottle bottom structure, including an inward concave curved surface 1 located in the center of the bottle bottom and six outward convex claws 2 evenly distributed around the inward concave curved surface 1. The root of the outward convex claws 2 is connected to the edge of the inward concave curved surface 1 through a transition arc 3 with continuous curvature.

[0019] Among them, the outwardly protruding claw 2 gradually widens from the root to the top along the radial direction of the bottle bottom; the included angle formed by the projection of the opposite side 4 of two adjacent outwardly protruding claws 2 onto a plane perpendicular to the axis of the bottle body is 55°~65°.

[0020] Furthermore, the radius of curvature of the concave surface 1 is 20~35mm. The choice of radius of curvature directly affects the support effect and pressure dispersion capability of the concave surface 1. A smaller radius of curvature will make the concave surface 1 more "sharp", while a larger radius of curvature will make the concave surface 1 more "gentle". The radius of curvature range of 20~35mm achieves the best balance between support strength and pressure dispersion.

[0021] In the above structure, the concave curved surface 1 provides support for the central area, the convex claw 2 transmits pressure evenly to all parts of the bottle bottom through circumferential uniform distribution and gradual width design, the continuous curvature design of the transition arc 3 avoids stress concentration, and the 55°~65° included angle formed by the side projection of the claw ensures the pressure dispersion effect between the claws.

[0022] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
