Description

Technical Field

[0001] The utility model relates to the technical field of bottle caps, in particular to a solid-liquid separation combined bottle cap structure which is pressed down to open with a cross S-shaped sealed bottom opening. Background Art

[0002] Beverages are ubiquitous on the market, and they typically use twist-on caps to seal the bottle. However, existing caps present certain drawbacks. First, their design is relatively simple, providing only a basic seal. Furthermore, mixing the solvent and water in the bottle can shorten the beverage's shelf life, creating inconvenience for consumers.

[0003] The patent with announcement number CN218641515U discloses a press-type solid-liquid separation bottle cap, comprising a cover body, a top cover positioned and installed on the top of the cover body, a pressing seat integrally positioned on the top cover, a pressing portion provided in the middle of the pressing seat, a barrel integrally positioned inside the cover body, a pressing cone positioned near the pressing portion inside the barrel, a solid-liquid separation seat connected to the bottom of the barrel, a sealing bayonet integrally connected to the bottom of the barrel, the position of the sealing bayonet engages and positions the solid-liquid separation seat, and a cover bottom is integrally formed at the bottom of the cover body. The press-type solid-liquid separation bottle cap described in the utility model is sealed between the barrel and the solid-liquid separation seat, can be quickly filled, and has an excellent sealing effect, can be used multiple times, is convenient for storing the material body, and adopts a press-type unsealing structure to mix the material body with the liquid in the bottle, thereby increasing the shelf life of beverages, etc., which is more practical.

[0004] The above-mentioned prior art achieves separation of the solid-liquid separation seat from the barrel and the sealing bayonet by pressing the pressing portion downward, causing the pressing cone to move downward and drive the solid-liquid separation seat to move downward, thereby allowing the powder inside the barrel to mix with the water in the bottle. However, since the pressing portion is exposed to the outside, when a foreign object accidentally collides with the pressing portion, it may cause the pressing portion to accidentally move downward, thereby causing the powder to leak from the barrel. In addition, in normal use, when the solid-liquid separation seat moves downward and separates from the barrel and the sealing bayonet, some of the powder may accumulate on the top of the solid-liquid separation seat and cannot be fully mixed with the water in the bottle, affecting the use effect. In view of this, we propose a solid-liquid separation combination bottle cap structure that is pressed down to open the cross S-shaped sealed bottom opening. Utility Model Content

[0005] The purpose of the utility model is to provide a solid-liquid separation combined bottle cap structure with a cross S-shaped sealed bottom opening that can be opened by pressing down, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] The press-down-open cross S-shaped sealed bottom-opening solid-liquid separation combined bottle cap structure comprises a sealed inner cap connected to the bottle mouth, the outer wall of the sealed inner cap is provided with a plurality of positioning slots arranged in a circular array, the outer side of the sealed inner cap is detachably connected to the outer protective cap, the inner wall of the outer protective cap is provided with a plurality of positioning inserts arranged in a circular array, the plurality of positioning inserts are respectively inserted into the plurality of positioning slots, so that the outer protective cap can be sleeved on the outer side of the sealed inner cap and is not easily displaced, thereby protecting the press soft cap and preventing foreign objects from directly colliding with the press soft cap. When it is necessary to press the top of the press soft cap downward, the user first moves the outer protective cap upward to separate the outer protective cap from the sealed inner cap.

[0008] The top of the positioning insert is provided with a retaining tooth, the top of the sealing inner cover is provided with a circular groove, a pressing soft cover is provided in the circular groove, and a cover edge is provided at the edge of the pressing soft cover. The bottom of the retaining tooth abuts against the top of the cover edge. The retaining tooth, the positioning insert and the outer protective cover are an integral injection-molded structure, and the retaining tooth can play a role in pressing the cover edge.

[0009] A cross-shaped piercing cone is provided in the middle of the top of the inner wall of the press-on soft cover, and a piercing tube is provided on the outer side of the cross-shaped piercing cone. The bottom end of the cross-shaped piercing cone protrudes from the bottom of the piercing tube to ensure that the cross-shaped piercing cone pierces the center opening first. A barrel connected to the circular groove is provided on the top of the inner wall of the sealed inner cover, and a sealing bottom film is provided at the bottom of the barrel. The outer side of the sealing bottom film is a conical structure. The press-on soft cover, the barrel and the sealing bottom film form a storage space. The material is stored in the storage space. A center opening is provided at the bottom end of the sealing bottom film, and an arc-shaped center opening is provided at the outer edge of the center opening. The center fracture makes a part of the center opening connected to the sealing bottom film to prevent the center opening from falling into the water in the bottle. The outer surface of the sealing bottom film is provided with multiple S-shaped easy-opening positions. When the cross-shaped piercing cone moves downward, the arc-shaped center fracture at the center opening position breaks first, and then the piercing tube continues to squeeze the inner side of the sealing bottom film. Since the sealing bottom film is subjected to the expansion force from the inside to the outside, the sealing bottom film is equally opened from the arc-shaped center fracture along the multiple S-shaped easy-opening positions, so that the material in the bottle cap is easier to fall into the water in the bottle, and no material is stuck at the opening, which can be better dissolved in the water in the bottle for drinking.

[0010] Preferably, an anti-theft ring is provided at the bottom of the sealed inner cover, and a plurality of anti-theft blocks are provided on the inner wall of the anti-theft ring, which is connected to the bottom of the bottle mouth. The sealed inner cover and the anti-theft ring are an integral injection-molded structure.

[0011] Preferably, a plurality of connecting bridges are provided on the top of the anti-theft ring, and the tops of the connecting bridges are fixedly connected to the bottom of the sealed inner cover. When the sealed inner cover is unscrewed, the plurality of connecting bridges will break, thereby separating the sealed inner cover from the anti-theft ring.

[0012] Preferably, the side surface of the inner wall of the sealing inner cap is provided with an internal thread for mounting and tightening with the screw thread of the bottle mouth. The top of the inner wall of the sealing inner cap is provided with an outer sealing ring for mounting on the water bottle. After the cap is mounted on the water bottle, the outer side of the bottle mouth is tightly fastened to the outer sealing ring to prevent air or pollutants outside the bottle from entering the bottle, thus achieving a sealing effect.

[0013] Preferably, an inner sealing ring is provided on the outer wall of the barrel near the top, which is used for fastening the inner side of the bottle mouth to the inner sealing ring after being installed on the water bottle, so that the water in the bottle does not flow out of the cover, thereby playing a sealing role.

[0014] Preferably, a bottom film deformation position is provided between the outer side of the bottom of the barrel and the outer side of the top of the sealing bottom film, to ensure that the sealing bottom film can be deformed and opened outward.

[0015] Preferably, the plurality of S-shaped easy-opening positions are arranged in a circular array, and the number of the S-shaped easy-opening positions is 2-4. The equally divided top opening method has a large opening area, and the material in the bottle cap is easier to fall into the water bottle without forming a stuck material at the opening, and can be better dissolved in the water in the bottle for drinking.

[0016] Preferably, a welding ring is provided at the bottom of the cover edge, and a welding groove is provided at the bottom of the inner wall of the circular groove and near the edge. The welding ring is ultrasonically welded in the welding groove. During ultrasonic welding, the welding ring melts in the welding groove, so that the cover edge and the sealed inner cover are welded and sealed into one as a package, thereby preventing material from leaking from the top of the barrel.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. This push-to-open, cross-S-shaped, sealed bottom-opening solid-liquid separation cap structure utilizes an outer protective cover and a push-on soft cover to enhance protection of the press section, preventing accidental collisions and powder leakage. The outer protective cover's positioning strips and slots ensure that the outer protective cover remains securely attached to the sealed inner cover when not in use, preventing displacement. When needed, the outer protective cover can be easily removed to enable the press-on operation, enhancing both safety and convenience.

[0019] 2. This push-to-open, cross-S-shaped, sealed bottom-opening, solid-liquid separation bottle cap structure achieves effective solid-liquid separation between powder and water through the design of the sealing bottom film, push-to-open soft cap, and barrel. The cross-shaped piercing cone at the top of the push-to-open soft cap works in conjunction with the piercing tube to gradually pierce the central opening of the sealing bottom film and the S-shaped easy-opening area on its outer surface. This allows the powder to smoothly fall into the bottle and fully mix with the water, preventing sticking and ensuring a uniform and pleasant beverage experience.

[0020] 3. This push-to-open, cross-S-shaped, sealed bottom-opening, solid-liquid separation bottle cap structure stores dry powder in the barrel and mixes it with water in the bottle before use. This prevents premature contact between the powder and water, effectively extending the shelf life of the beverage. The sealed bottom design ensures that the material is mixed with water only when needed, preserving the freshness and flavor of the beverage.

[0021] 4. This push-to-open, cross-S-shaped sealed bottom-opening, solid-liquid separation cap features a cross-shaped top-penetrating cone and an S-shaped easy-opening area. This ensures that when pressed, the sealing film breaks evenly from the center opening and opens along the S-shaped easy-opening area. This design allows the contents of the cap to fall into the water over a large area, preventing material from getting stuck at the opening. This improves the mixing efficiency of the material and water, allowing the beverage to dissolve quickly and be consumed by the consumer. BRIEF DESCRIPTION OF THE DRAWINGS
