Description

Technical Field

[0001] The utility model relates to the technical field of beverages, in particular to a twist-type downward-opening ultrasonic welding sealed solid-liquid separation bottle cap. Background Technique

[0002] Liquid beverage is a new type of drink. Its main component is water, plus some other substances such as sugar, fruit juice, tea, coffee, plant components, etc.; compared with traditional beverages, liquid beverages emphasize more on the comfort and taste experience during the drinking process; in order to improve the shelf life, preservatives are often added to the liquid; as people pay more and more attention to human health, there have emerged solid beverages and separated drinks.

[0003] The Chinese patent discloses a press-combined sealed piercing-type solid-liquid separation bottle cap (authorization publication number CN220949335U). The bottle cap body of this patented technology and the sealed bottom of the lid body for placing solid materials are integrally injection-molded. The bin and the bottle cap body are stabilized and sealed through the first lid body sealing ring, the second lid body sealing ring, the first bin sealing ring and the second bin sealing ring, thus well avoiding the water in the bottle contacting the solid materials; the design of the cross cone and the cross groove allows the user to easily pierce the sealed bottom of the lid body; the piercing support column can enlarge the opening of the sealed bottom of the lid body, accelerating the dropping of the solid materials, but it needs to be pressed hard by hand to mix the solid beverage with water, and the operation is inconvenient. Content of the Utility Model

[0004] The purpose of the utility model is to provide a twist-type downward-opening ultrasonic welding sealed solid-liquid separation bottle cap to solve the problems put forward in the above background technique.

Specific implementation mode

[0019] Please refer to Figures 1 to 4 , in the embodiment of the present utility model, a twist-type downward-opening ultrasonic welding sealed solid-liquid separation bottle cap includes a lower main cover outer shell 3 and a lower main cover inner shell 8, and an upper sealing cover 1 fixed to the upper end of the lower main cover inner shell 8 by ultrasonic welding. The upper end of the inner side wall of the lower main cover outer shell 3 is fixedly connected to the lower main cover inner shell 8. The inner side of the lower main cover inner shell 8 forms a lower cover bin 5 for storing powdered or granular solid beverages. And at the lower end of the outer side wall of the lower main cover inner shell 8, a staggered penetration position ring 7 is connected. The lower end of the inner side wall of the staggered penetration position ring 7 is connected to a staggered penetration position piece 13 in a scissor-mouth manner. And a lower cover limit ring 6 is fixedly connected to the outside of the staggered penetration position ring 7. The lower main cover outer shell 3, the lower main cover inner shell 8, the staggered penetration position ring 7, the staggered penetration position piece 13 and the lower cover limit ring 6 are of an integrally injection-molded structure, so that the joints between the lower main cover inner shell 8 and the staggered penetration position ring 7, and between the staggered penetration position ring 7 and the staggered penetration position piece 13 all have good sealing effects, preventing the liquid in the beverage bottle from seeping into the solid beverage in the lower cover bin 5; when the bottle cap is tightened clockwise, the bottle cap generates a downward acting force, and the mouth of the beverage bottle pushes upward against the lower cover limit ring 6, and the joint between the lower main cover inner shell 8 and the staggered penetration position ring 7 is disconnected, and the lower main cover inner shell 8 and the staggered penetration position ring 7 are separated; when the bottle cap is further rotated clockwise, the bottom of the lower main cover inner shell 8 continues to move downward, and the joint between the staggered penetration position ring 7 and the staggered penetration position piece 13 is disconnected, and the staggered penetration position ring 7 and the staggered penetration position piece 13 are separated, and the sealed solid beverage stored in the lower cover bin 5 can then smoothly fall into the beverage bottle. Shake the beverage bottle vigorously to dissolve the solid beverage in the water, and a liquid beverage for the user to drink is formed.

[0020] In Figure 1 and Figure 3 , on the outer side of the lower end of the upper sealing cover 1, a welding ring 2 is fixedly connected in a ring shape. An annular welding groove 4 is opened on the inner side of the upper end of the lower main cover outer shell 3. The welding ring 2 and the welding groove 4 are matched. After putting the powdered or granular solid beverage into the lower cover bin 5, the welding ring 2 is melted into the welding groove 4 by an ultrasonic welding device, so that the upper sealing cover 1 and the lower main cover inner shell 8 are welded into one body; the lower cover bin 5 then forms a closed structure, isolated from the outside air, and the powdered or granular solid beverage in the lower cover bin 5 can be safely stored.

[0021] In Figure 1, Figure 2 and Figure 3 In Figure 2 and Figure 3 , an anti-theft ring 14 is provided at the lower end of the lower main cover outer shell 3. A tear-off part is provided on one side of the anti-theft ring 14. The lower main cover outer shell 3 and the anti-theft ring 14 are of an integrally injection-molded structure. After tearing off the anti-theft ring 14 from the bottle mouth of the beverage bottle from the tear-off part, the bottle cap can be continuously screwed down clockwise.

[0022] In Figure 3 and Figure 4 In Figure 3 and Figure 4 , an inner seal 12 is fixedly connected to the inner side of the lower end of the lower cover limiting ring 6, and an outer seal 11 is fixedly connected to the outer side of the lower end of the lower cover limiting ring 6. When the bottle mouth of the beverage bottle abuts against the lower end of the lower cover limiting ring 6, the inner seal 12 fits against the inner side of the bottle mouth of the beverage bottle, thereby sealing the bottle mouth of the beverage bottle to prevent external air from entering the bottle and causing pollution of the water body in the bottle; the outer seal 11 fits against the outer side of the bottle mouth of the beverage bottle to prevent the water in the beverage bottle from leaking out from the bottle mouth.

[0023] In Figure 3 and Figure 4 In Figure 3 and Figure 4 , a bottle cap thread 9 is provided at the lower end of the inner side wall of the lower main cover outer shell 3. The lower main cover outer shell 3 can be engaged with an external beverage bottle through the bottle cap thread 9; a limit pin 10 is provided between the lower cover limiting ring 6 and the lower main cover outer shell 3. When the bottle cap is screwed down along the bottle mouth of the beverage bottle, after the limit pin 10 breaks through the restraint of the bottle cap thread 9 due to the acting force, the lower cover limiting ring 6 is no longer limited and fixed, and the bottle cap can be further screwed down.

[0024] In Figure 3 In Figure 3 , a cavity is provided between the lower main cover outer shell 3 and the lower main cover inner shell 8. An inclined opening limit pin 15 is fixedly connected in the cavity. When the bottle cap is continuously screwed down, the lower cover limiting ring 6 is lifted by the bottle mouth of the beverage bottle in the cavity. When it reaches the inclined opening limit pin 15, the lower main cover inner shell 8 is extruded from the outside by the inclined opening limit pin 15, making the bottom of the lower main cover inner shell 8 funnel-shaped, thereby effectively preventing solid beverages from spilling.

[0025] This bottle cap can be used for the installation and production of water bottles and beverage bottles with 28 mouths, 3025 mouths, and 38 mouths, and can also be used for the installation and production of water bottles and beverage bottles of other models.

[0026] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent replacements or changes, and should be covered within the protection scope of the present invention.
