Description

Technical Field

[0001] This utility model relates to the field of liquid dispensers, and more particularly to a concave-bottom bottle. Background Technology

[0002] Ordinary liquid dispenser bottles are typically designed with a protruding bottom to ensure they don't bulge out, making them easy to place on a flat surface, or to prevent any sediment from being sucked up. However, this design has a drawback: the liquid may not be completely sucked up, or the straw may need to be artificially lengthened and pushed to the edge of the bottle to avoid the protrusion. In this case, when installing the pump head after filling, the straw will hit the bottom of the bottle, making it difficult to tighten the pump head or causing the cap to tilt. In addition, if the liquid is a highly viscous paste, even if the straw is lengthened and pushed to the concave edge of the bottle bottom, the poor flowability of the paste-like liquid will prevent it from being completely sucked up.

[0003] Thus, the concave-bottom bottle was born. The concave bottom of the bottle is concave, which allows the liquid to flow or settle into the concave part under the action of gravity, so that the liquid distributor can draw in or pump out as completely as possible. Usually, an additional base is required to fit the bottom of the concave-bottom bottle to ensure that it can stand upright. However, the bottle body and the base need to be molded by blow molding and injection molding processes respectively, and the quality of the fit is difficult to guarantee, which affects the appearance. On the other hand, the one-piece concave-bottom bottle design has a thicker material around the bottom, which makes it difficult to ensure the uniform thickness of the bottom during blow molding. Blow molding is difficult to achieve, there are many restrictions on materials, and the scrap rate is high. Utility Model Content

[0022] To better understand the purpose, structure, and function of this utility model, the following detailed description of a specific embodiment of the "concave bottom bottle" of this utility model is provided in conjunction with the accompanying drawings.

[0023] See Figures 1-4 In this embodiment, the concave-bottom bottle includes a detachably fixed bottle body 100 and a base 200; the base 200 includes a base support 201, on which a bowl-shaped concave plate 202 is fixedly disposed; the bottom of the bottle body 100 is provided with an opening 101, and a connector 102 is provided around the opening 101, the connector 102 being detachably fixedly connected to the base support 201; the inner wall of the bottle body 100 is provided with an abutment groove 103, and the edge of the bowl-shaped concave plate 202 is fitted into the abutment groove 103 to achieve a sealed connection between the bowl-shaped concave plate 202 and the bottle body 100. Preferably, both the bottle body 100 and the base 200 are integrally injection molded to improve sealing performance. This concave-bottom bottle is made by separately manufacturing the bottle body 100 and the base 200 and then combining them to form a sealed concave-bottom bottle. It eliminates the need for blow molding to form the concave bottom, solving the problem of difficult blow molding, reducing production difficulty, and improving the finished product qualification rate. At the same time, the base support 201 of the base 200 supports the concave-bottom bottle to stand upright. The base 200 and the bottle body 100 are fixedly connected, eliminating the need for an additional base and making it convenient to use.

[0024] Meanwhile, when the concave-bottom bottle is used with the straw pump head, the straw is inserted into the concave part in the middle of the bowl-shaped concave plate 202. Under the action of gravity, the liquid enters the concave part in the middle along the concave surface of the concave plate. By pressing the pump head to suck out the liquid, the liquid can be completely sucked out for use without any residue.

[0025] See further Figure 3 and Figure 4 In this embodiment, the periphery of the opening 101 extends outward and downward to form a connector 102. The inner wall of the connector 102 is provided with an annular protrusion 104, and the side wall of the base 201 is provided with an annular groove 203. The annular protrusion 104 is fitted into the annular groove 203 to realize the snap-fit ​​connection between the connector 102 and the base 201, which is convenient for disassembly and assembly.

[0026] More specifically, in this embodiment, the base 201 is symmetrically provided with a plurality of limiting openings 205, and the inner wall of the bottle body 100 extends downward to form a plurality of reinforcing columns 105. When the bottle body 100 and the base 200 are combined, the reinforcing columns 105 pass through the limiting openings 205 to strengthen the connection strength between the bottle body 100 and the base 200, strengthen the structural strength of the bottom of the bottle body 100, and prevent the bottle body 100 from deforming during use.

[0027] See further Figure 4In this embodiment, a support rib 204 is provided between the outer wall of the bowl-shaped concave plate 202 and the base 201 to improve the structural strength of the base 200, improve the connection strength between the bowl-shaped concave plate 202 and the base 201, ensure that the edge of the bowl-shaped concave plate 202 will not deform when it is fitted into the sealing groove 103, and improve the yield rate of the base 200 during integral injection molding.

[0028] See further Figure 2 and Figure 3 In this embodiment, the inner wall of the bottle body 100 is provided with a limiting protrusion 106 to abut against the edge of the bowl-shaped concave plate 202, thereby improving the tightness of the connection between the bowl-shaped concave plate 202 and the inner wall of the bottle body 100. An abutment groove 103 is formed between the limiting protrusion 106 and the inner wall of the bottle body 100. In order to improve the sealing of the connection between the bowl-shaped concave plate 202 and the inner wall of the bottle body 100, a waterproof rubber ring can be provided in the abutment groove 103.
