Description

Technical Field

[0001] The utility model relates to the technical field of beverage packaging, in particular to a flip-top combined cover. Background Art

[0002] Currently, beverages on the market need to be filled in advance and then transported over long distances to various places for sale, and delivered to users in the form of finished liquid products. Long-term transportation can easily lead to losses such as precipitation, decomposition, and deterioration of the nutrients and effective ingredients of the beverages. The beverage solutes currently used to mix liquid beverages are all individually packaged, which is unhygienic during mixing and inconvenient for users to carry.

[0003] To solve this problem, the prior art (CN220181548U) proposes a bottle cap that facilitates the rapid dissolution of ingredients. Although it realizes solid-liquid separation and is ready for use, its cap body structure is complex, resulting in a complex corresponding injection mold structure, which greatly increases the production cost of the cap body; at the same time, its top cover is threadedly connected to the ingredient containing shell. In order to ensure the strength of the threaded connection, its mating length is long, which increases the overall length of the cap body. Utility Model Content

DETAILED DESCRIPTION

[0026] The following will be combined with the embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0028] Example:

[0029] like Figure 1-Figure 5 As shown, a flip-top combined cover comprises an upper cover 1, a middle cover 2 and a lower cover 3, wherein the lower cover 3 is connected to the bottle mouth 20, the middle cover 2 is coaxially arranged inside the lower cover 3, and the upper cover 1 is arranged on the top of the middle cover 2 for sealing the middle cover 2;

[0030] The bottom of the middle cover 2 is provided with a conical top-penetrating portion 4, a discharge gap is provided between the top-penetrating portion 4 and the bottom of the middle cover 2, and a sealed solute containing cavity is formed between the inner cavity of the middle cover 2, the top-penetrating portion 4 and the inner wall of the lower cover 3;

[0031] The middle cover 2 is rotatably connected to the lower cover 3 , and the middle cover 2 pushes through the bottom of the lower cover 3 axially downward when rotating.

[0032] The circumferential walls of the upper cover 1 and the middle cover 2 are both solid wall structures without any openings or grooves.

[0033] The outer wall of the middle cover 2 is provided with an arc-shaped sliding groove 5, and the inner wall of the lower cover 3 is provided with a sliding block 6 slidably matched with the sliding groove 5. The middle cover 2 is slidably connected to the lower cover 3 through the sliding groove 5 and the sliding block 6.

[0034] The slide groove 5 includes two arcuate ribs 7 , and the same end of the two arcuate ribs 7 is connected (sealed) by a limiting rib 8 .

[0035] An easy-tear sleeve 9 is disposed on the top of the lower cover 3 , and a support ring 10 is disposed on the outer wall of the middle cover 2 , wherein the bottom surface of the support ring 10 abuts against the top surface of the easy-tear sleeve 9 .

[0036] The tear-away cover 9 includes a support portion 11 and a connecting portion 12. The support portion 11 is annular in structure and is provided with a notch. The upper and lower sides of the connecting portion 12 are respectively connected to the lower side of the support portion 11 and the upper side of the lower cover 3 through tear-away tapes. One end of the connecting portion 12 extends vertically to form a connecting tape 13. The connecting tape 13 is adapted to the notch and is connected to the side wall of the notch through the tear-away tape.

[0037] The tearable tape is a thin-walled or continuously arranged dot-shaped structure.

[0038] A shifting block 14 is provided on the top of the connecting belt 13. The shifting block 14 is provided to facilitate the application of force to the easy-tear belt.

[0039] Among them, 1. The lower cover 3 is snap-fitted with the bottle mouth 20, and the connection method is the existing technology, and the specific structure is not repeated here. 2. When the bottle cap as a whole is matched with the bottle body, the solute receiving cavity in the bottle cap is filled with solute, which can be liquid or solid. 3. The bottom of the lower cover 3 is a multi-petal structure, and the adjacent petals are connected by a thin wall; the bottom of the lower cover 3 can also be set as a film structure.

[0040] 4. The bottom of the lower cover 3 is sealed by a sealing part, and the sealing part includes two semicircular baffles, which are respectively hinged to the bottom of the lower cover by hinges, and the two baffles are connected by a thin wall, and the baffles are connected to the inner wall or end surface of the lower cover by a thin wall. In this way, when the bottom of the lower cover is penetrated, the hinge can prevent the baffle from falling into the bottle.

[0041] Working principle: (1) The tear-off tape is torn off, and the notch is exposed during the tear-off process, and the tear-off tape is separated from the top of the lower cover 3. The notch is provided to facilitate the removal of the tear-off sleeve 9 from the lower cover 3.

[0042] (2) After the easy-tear sleeve 9 is removed, there is an axial movement gap between the middle cover 2 and the lower cover 3, and the axial movement gap is the length of the easy-tear sleeve 9. At this time, the middle cover 2 is rotated. Since the middle cover 2 is not axially limited by the easy-tear sleeve 9, when the middle cover 2 is rotated, the middle cover 2 moves downward along the axial direction of the lower cover 3 under the action of the slider 6 and the slide groove 5.

[0043] When the middle cover 2 moves downward, the penetration portion 4 at the bottom thereof penetrates the bottom of the lower cover 3, and the solute in the solute containing chamber falls into the bottle. The bottle body is shaken to mix the solute with the liquid in the bottle, and the upper cover 1 can be opened for drinking.

[0044] The combined cap of the utility model has a simple structure, and the middle cap 2 can penetrate the lower cap 3 without a complicated thread structure, thus simplifying the bottle cap structure. The corresponding bottle cap forming mold has a simple structure, which is beneficial to reducing the production cost of the bottle cap.

[0045] Furthermore, if Figure 2 , Figure 4 and Figure 5 As shown, the upper cover 1 is snap-connected with the top of the middle cover 2, and the upper cover 1 is a flip cover 16 type structure.

[0046] The upper cover 1 includes a bottle cap seat 15 and a flip cover 16, wherein the flip cover 16 is hinged to the bottle cap seat 15 via a hinge band 17, a clamping rib 18 is provided on the inner wall of the bottle cap seat 15, and an annular clamping platform 19 is provided on the outer wall of the middle cover 2, wherein the bottle cap seat 15 is clamped to the middle cover 2 via clamping and the clamping platform 19. The bottle cap seat 15 and the flip cover 16 are connected via a dot-shaped tear line except for the hinge band 17.

[0047] The flip cover 16 is provided with a groove to facilitate manual force to open the flip cover 16 .

[0048] When the upper cover 1 needs to be opened, the flip cover 16 is forced upward by the groove, and the tear line is broken to open the flip cover 16. The bottle cap seat 15 is connected with the middle cover 2 by a clamping method, eliminating the threaded connection structure, and reducing the size of the connecting portion 12 between the bottle cap seat 15 and the middle cover 2, making the bottle cap lightweight.

[0049] The above is only a preferred embodiment of the utility model. It should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not deviate from the spirit and scope of the utility model, and should be within the scope of protection of the claims attached to the utility model.
