Description

Technical Field

[0001] The invention belongs to the technical field of beverage packaging, and particularly relates to a flip-top storage bottle head and a filling method thereof. Background Art

[0002] Most beverages are made by adding flavoring ingredients to pure water. Separately stored honey beverages store honey and water separately and then reconstitute them when drinking, ensuring the natural flavor of honey. Its fresh taste and healthy quality are increasingly popular among the public. However, existing instant beverage bottles mostly use a design in which the bottle head and bottle body are separated. When drinking, the bottle head is removed as a whole, which easily causes residual beverage to drip and cause contamination, resulting in a poor customer experience. At the same time, the unscrew bottle cap needs to be stored separately when drinking and is prone to falling and causing contamination. In addition, the existing side wall opening has the defect that it is difficult to fully flow out and mix the stored materials in the bottle head. Summary of the Invention

[0003] In response to the shortcomings of the existing technology, the purpose of the present invention is to provide a flip-top storage bottle head and a filling method thereof. The upper cover adopts a flip-top design, and the bottle head and sealing cover do not need to be stored separately during use, thereby preventing liquid dripping. At the same time, the ingredients in the cavity are allowed to flow into the bottle body by puncturing, and the beverage flows out more smoothly.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] A flip-top storage bottle head comprises an upper cover, a middle cover and a lower cover;

[0007] The middle cover is a through-type cylindrical structure formed by connecting an upper tube and a lower tube of different diameters. The upper tube is larger in diameter than the lower tube. The lower tube is a straight cylindrical structure. A convex ring for connecting with the upper cover is provided near the top of the upper tube. Two chute grooves spiraling upward to the right are provided on the outer side of the middle of the upper tube. A poking cone is connected to the bottom end of the lower tube. A plurality of vertical holes are symmetrically provided on the poking cone.

[0008] The lower cover is a cylindrical structure with an open top, consisting of an outer cylinder and an inner cylinder nested together. The inner cylinder is connected to the outer cylinder with a gap formed between them. The inner wall of the outer cylinder is provided with a thread, and the lower edge of the inner wall of the outer cylinder is provided with a buckle.

[0009] Two guide posts are symmetrically arranged on the inner wall of the inner cylinder corresponding to the slide grooves. When the middle cover is inserted into the lower cover, the two guide posts are respectively located in the two slide grooves of the upper cylinder. An easy-tear ring for limiting is connected to the top of the inner cylinder, and a conical bottom seal is provided at the bottom end of the inner cylinder.

[0010] The middle cover is inserted into the lower cover, and the top of the middle cover is sealed by the sealing cover of the upper cover, forming a chamber for storing ingredients in the lower cover; the easy-tear ring is torn off, and the middle cover can be moved up and down in the lower cover through the cooperation of the guide column and the slide groove. The poke cone moves downward to pierce the conical bottom seal of the lower cover, and the ingredients in the chamber flow into the bottle through the rupture.

[0011] The present invention also has the following technical features:

[0012] Preferably, a retracting card platform is provided at the lower part of the inner cylinder of the lower cover; the outer diameter of the lower cylinder is smaller than the inner diameter of the retracting card platform;

[0013] The bottom of the upper cylinder of the middle cover and the retracting clamping platform are correspondingly provided with sealing clamping rings.

[0014] Preferably, limit sealing rings are provided at the upper and lower ends of the chute, and the two chute openings facing each other are separated by vertical edges.

[0015] Preferably, the upper end surface of the guide pillar is configured as an inclined surface on a side away from the inner wall of the inner cylinder.

[0016] Preferably, the cross section of the poking cone is cross-shaped.

[0017] Preferably, a groove for facilitating opening of the cover is provided on the side of the outer wall of the sealing cover opposite to the flexible connecting block.

[0018] Preferably, the inner top of the upper cover is provided with a sealing groove which engages with the top of the middle cover during assembly.

[0019] Preferably, the outer circumference of the outer cylinder is provided with anti-slip grooves.

[0020] Preferably, limited anti-skid columns are correspondingly provided on the inner wall of the sealing cover and the outer wall of the upper portion of the upper cylinder convex ring.

[0021] The present invention also protects a method for filling the flip-top storage bottle head as described above, comprising the following steps:

[0024] S3. Assemble the upper cover on the top of the middle cover until the connecting clamp is clamped on the lower part of the convex ring of the upper cylinder, and the connection point is located on the outer periphery of the convex ring.

[0025] Compared with the prior art, the present invention has the following technical effects:

[0026] The upper cover of the present invention adopts a flip-top design, and the bottle body and the cover are integrated into one body. When drinking, the bottle body and the bottle head do not need to be separated, which avoids residual liquid dripping on the bottle head to cause pollution and inconvenience in storing the bottle cap.

[0027] In order to achieve automated assembly and improve assembly efficiency, the upper end surface of the guide pillar is set as an inclined surface on the side away from the inner wall of the inner cylinder, which enables the rapid assembly of the middle cover and the lower cover. At the same time, multiple vertical holes are symmetrically opened on the poke cone. The cross-section of the poke cone is cross-shaped, which facilitates the flow of liquid through.

[0039] The specific contents of the present invention are further explained in detail below with reference to the embodiments.

[0040] like Figures 1 to 6 As shown, this embodiment provides a storage bottle head, including an upper cover 1, a middle cover 2 and a lower cover 3;

[0041] The upper cover 1 includes a connecting ring 101, one side of which is provided with a flexible connecting block 102. The upper end of the flexible connecting block 102 is connected to a sealing cover 103 for sealing the middle cover 2. In the sealed state, multiple connection points 104 are provided between the connecting ring 101 and the sealing cover 103 to prevent theft.

[0042] The middle cover 2 is a through-type cylindrical structure formed by connecting an upper tube 201 and a lower tube 202 of different diameters. The upper tube 201 is larger in diameter than the lower tube 202. The lower tube 202 is a straight cylindrical structure. A convex ring 4 for connecting with the upper cover 1 is provided near the top of the upper tube 201. Two chute grooves 5 that spiral upward to the right are provided on the outer side of the middle of the upper tube 201. The bottom end of the lower tube 202 is connected to a poking cone 6. A plurality of vertical holes 7 are symmetrically opened on the poking cone 6 to facilitate the flow of liquid.

[0043] The lower cover 3 is a cylindrical structure with an open top, consisting of an outer cylinder 301 and an inner cylinder 302 nested together. The inner cylinder 302 is connected to the outer cylinder 301 with a gap formed between the inner cylinder 302 and the outer cylinder 301. The inner wall of the outer cylinder 301 is provided with a thread, and the lower edge of the inner wall of the outer cylinder 301 is provided with a buckle 18.

[0044] Two guide posts 8 are symmetrically arranged on the inner wall of the inner cylinder 302 corresponding to the chute 5. When the middle cover 2 is inserted into the lower cover 3, the two guide posts 8 are respectively located in the two chute 5 on the upper cylinder 201. The middle cover 2 can move up and down in the lower cover 3 through the cooperation between the guide posts 8 and the chute 5. The top of the inner cylinder 302 is connected to an easy-tear ring 9 for limiting the position, and the bottom of the inner cylinder 302 is provided with a conical bottom seal 10. To facilitate puncturing, a tear line with a weak connection is preset on the conical bottom seal 10. When the puncturing cone 6 moves downward and applies force to the conical bottom seal 10, the conical bottom seal 10 is torn along the tear line to form a rupture.

[0045] The middle cover 2 is inserted into the lower cover 3, and the top of the middle cover 2 is sealed by the sealing cover 103 of the upper cover 1, forming a chamber for storing ingredients in the lower cover 3; the easy-tear ring 9 is torn off, and the middle cover 2 is moved up and down in the lower cover 3 by the cooperation of the guide column 8 and the slide groove 5. The poking cone 6 moves downward to pierce the conical bottom seal 10 of the lower cover 3, and the ingredients in the chamber flow into the bottle through the rupture.

[0046] The lower part of the inner cylinder 302 of the lower cover 3 is provided with a retracting card platform 11; the outer diameter of the lower cylinder 202 is smaller than the inner diameter of the retracting card platform 11; when the middle cover 2 moves downward in the lower cover 3, the lower cylinder 202 passes through the retracting card platform 11 and moves downward along the inner cylinder 302.

[0047] A sealing snap ring 12 is provided at the bottom of the upper cylinder 201 of the middle cover 2 corresponding to the retracting clamping platform 11. When the middle cover 2 moves downward in the lower cover 3 until the sealing snap ring 12 is clamped on the retracting clamping platform 11, the middle cover 2 and the lower cover 3 are relatively sealed.

[0048] Limiting sealing rings 13 are provided at the upper and lower ends of the chute 5. The limiting sealing rings 13 are used to achieve relative limiting between the chute 5 and the guide pillar 8, and at the same time form a sealing ring between the inner walls of the middle cover 2 and the lower cover 3 to prevent the liquid ingredients in the storage chamber from leaking;

[0049] The two oppositely-opened chute grooves 5 are separated by a vertical ridge 14 , so that the two groups of chute grooves 5 and the guide pillars 8 precisely correspond to each other, thereby achieving stable up and down movement between the middle cover 2 and the lower cover 3 .

[0050] To facilitate assembly, the upper end surface of the guide pillar 8 is configured as an inclined surface on a side away from the inner wall of the inner cylinder 302 .

[0051] In order to achieve shorter distance injection during industrial molding, improve the yield rate of the injection molded parts, reduce industrial costs, and facilitate the flow of liquid, the cross section of the piercing cone 6 is designed to be cross-shaped.

[0052] A groove 20 for facilitating opening of the cover is provided on the outer wall of the sealing cover 103 on a side opposite to the flexible connecting block 102 .

[0053] In order to enhance the sealing performance, a sealing groove 15 is provided on the top of the upper cover 1 to be engaged with the top of the middle cover 2 during assembly.

[0054] The outer circumference of the outer cylinder 301 is provided with anti-slip grooves 16, and the inner wall of the sealing cover 103 and the outer wall of the upper part of the convex ring 4 of the upper cylinder 201 are correspondingly provided with limited anti-slip columns 17. The limited anti-slip columns 17 increase the friction force to facilitate the screwing of the upper cover 1 so that the middle cover 2 moves up and down in the lower cover 3. The poke cone 6 moves downward to pierce the conical bottom seal 10 of the lower cover 3, and the ingredients in the chamber flow into the bottle through the rupture. The anti-slip grooves 16 facilitate assembly.

[0055] The beverage bottle equipped with the flip-top storage bottle head of this embodiment includes a bottle body, a neck with external threads on the top of the bottle body, and the bottle body is connected to the outer cylinder 302 of the flip-top storage bottle head through the neck thread. A locking platform 19 is provided below the external threads of the neck of the bottle head, which is compatible with the ring buckle 18. The ring buckle 18 and the locking platform 19 cooperate to lock and seal the bottle body and the bottle head.

[0056] The flip-top storage bottle head of the present invention comprises the following steps during filling:

[0057] S1. Insert the middle cover 2 into the lower cover 3, with the outer chute 5 of the middle cover 2 aligned with the guide post 8, so that the guide post 8 is located at the lowest point in the chute 5. A cavity for storing honey is formed in the middle cover 2. Then, assemble the upper cover 1 and seal the top of the middle cover 2 with the sealing cap 103 of the upper cover 1. A cavity for storing ingredients is formed in the lower cover 3.

[0058] S3, inject honey solute into the middle cover 2;

[0059] S3. Assemble the upper cover 1 on the top of the middle cover 2 until the connecting clamp 101 is clamped on the lower part of the convex ring 4 of the upper tube 201, and the connection point 104 is located on the outer periphery of the convex ring 4. The inner wall of the sealing cover 103 and the limiting anti-slip column 17 on the outer wall of the upper tube 201 above the convex ring 4 are clamped with each other to achieve sealing on the top of the middle cover 2; the connection point 104 plays an anti-theft role; the top of the inner tube 302 of the lower cover 3 is connected with an easy-tear ring 9 for limiting.

[0060] When it is necessary to prepare a drink, tear off the easy-tear ring 9, grab the upper cover 1 and rotate it. Due to the action of the limiting anti-slip column 17, the upper cover 1 and the middle cover 2 are relatively fixed, and the torsional force is transmitted to the middle cover 2. The two guide columns 8 inside the lower cover 3 slide to the highest point in the slide groove 5 of the middle cover 2, and the middle cover 2 moves downward in the lower cover 3. The lower cylinder 202 passes through the indentation card platform 11 and moves downward along the inner cylinder 302 until the sealing clamp ring 12 is stuck on the indentation card platform 11. The poking cone 6 moves downward to poke the conical bottom seal 10 of the lower cover 3. The upper cover 1 is broken, and the ingredients in the chamber flow into the bottle through the broken hole. The bottle can also be shaken to allow water in the bottle body to enter the middle cover 2 through the broken hole for flushing, and the honey enters the bottle. After shaking, the groove 20 of the upper cover 1 is pressed upward to break the connection of the connection point 104, and the sealing cover 103 is opened. The mixed beverage enters the middle cover 2 through the broken hole of the lower cover 3 and flows out, and then it can be drunk. The operation is simple and the use is convenient. There is no need to remove the bottle head when drinking. The operation is convenient and the residual liquid in the bottle head is avoided from dripping and causing pollution.
