Description

Technical Field

[0001] This utility model relates to the field of beverage packaging, specifically to a beverage bottle with a puncture function. Background Technology

[0002] Current beverage bottles typically employ a one-piece structure, directly encapsulating the liquid contents within a single bottle. For beverages that require separate storage, such as those containing additives like honey or concentrated fruit juice, traditional packaging methods suffer from problems like premature dissolution of the additives leading to flavor loss and shortened shelf life.

[0003] Currently, most split-type beverage bottles on the market use a structure where individually packaged additive capsules are combined with the main bottle body. Mixing requires manual squeezing or puncturing the capsule. However, this type of structure generally has the following drawbacks: First, the outer diameter of the connection between the capsule and the bottle body is inconsistent, resulting in a poor grip and unattractive appearance; second, the puncturing mechanism is difficult to operate, easily leading to incomplete puncture or accidental leakage; third, premature puncture can easily occur due to misoperation during assembly, affecting product safety. Utility Model Content

[0004] In view of the above, the purpose of this utility model is to provide a beverage bottle with a puncture function to solve the problems of the existing split beverage bottles, such as their abrupt appearance, inconvenient operation, and insufficient safety.

[0005] This invention discloses a beverage bottle with a puncture function, comprising a bottle body, a storage bottle, a puncture component, an inner cap, and an outer cap. The bottle body has a receiving cavity with a top opening and a first bottle mouth with circumferential threads; the storage bottle has the same outer diameter as the bottle body and includes a sealed cavity for storing contents and a connecting wall extending radially from the outer periphery of the sealed cavity. The upper section of the connecting wall has internal threads, and the storage bottle is screwed to the first bottle mouth of the bottle body via a threaded pair; the puncture component is axially movably disposed within the sealed cavity; the top of the storage bottle has a second bottle mouth, and the inner cap is screwed to the second bottle mouth. The inner cap has a driving structure, which is motion-coupled with the puncture component, such that when the inner cap is unscrewed, it drives the puncture component to axially descend and puncture the bottom of the storage bottle; the outer cap is coaxially sleeved outside the inner cap, its outer diameter is the same as the bottle body, and it is detachably connected to the inner cap.

[0006] Furthermore, the driving structure includes an annular guide wall disposed in the inner cover, the inner circumference of which is provided with a radially protruding first transmission boss, the first transmission boss having a first abutment surface and a first transmission ramp; the outer circumference of the piercing member is provided with a second transmission boss, the second transmission boss having a cooperating second abutment surface and a second transmission ramp; the first abutment surface and the second abutment surface constitute a rotary drive pair, the first transmission ramp and the second transmission ramp constitute a ramp sliding transmission, when the inner cover is opened, the first transmission ramp on the inner cover slides into contact with the second transmission ramp on the piercing member, generating an axial component force to push the piercing member downward to pierce the bottom of the storage bottle.

[0007] Furthermore, the outer periphery of the puncturing member is provided with a circumferential array of elastic guide grooves, one of which forms an inlet angle; the inner wall of the sealed cavity is provided with an axial limiting ridge corresponding to the guide groove, and the axial limiting ridge is provided with a guide slope at the inlet angle; when the inner cover is screwed closed, the rotation drive pair drives the puncturing member to rotate; the inlet angle and the guide slope cooperate to guide the guide groove to undergo elastic deformation and cross the limiting ridge so that the inner cover can be screwed closed normally, and at the same time, after the inner cover is screwed closed, at least one set of guide grooves and limiting ridges maintain sliding cooperation to maintain axial guidance.

[0008] Furthermore, the inner wall of the outer cover is provided with elastic snap-fit ​​protrusions, which engage with the inner cover to achieve a detachable connection.

[0009] The beneficial effects of this utility model are as follows:

[0010] 1. Appearance and feel optimization: The outer diameter of the storage bottle and the outer cap are consistent with the bottle body. Combined with the smooth transition design of the connecting wall, the overall structure is not abrupt, the grip is comfortable, and the product quality is enhanced.

[0011] 2. High-efficiency transmission structure: The rotational motion of the inner cover is converted into the axial movement of the piercing component through inclined plane sliding transmission. Compared with traditional thread transmission, it is more labor-saving and the piercing action can be completed with a single rotation, making it easy to operate.

[0012] 3. Safety protection design: The combination of the elastic guide groove and the axial limiting ridge ensures normal assembly when the inner cover is screwed closed, while avoiding accidental puncture during assembly. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Reference Figure 1-2 , Figure 4-13 As shown, a beverage bottle with a puncture function in this embodiment includes a bottle body 1, a storage bottle 2, a puncture component 3, an inner cap 4, and an outer cap 5.

[0027] Bottle body 1, storage bottle 2, puncture part 3, inner cap 4, and outer cap 5 are all made of plastic injection molding.

[0028] The receiving cavity 101 of the bottle body 1 is used to store the main beverage, and the outer periphery of the first bottle mouth 102 is provided with threads.

[0029] The outer diameter of storage bottle 2 is consistent with that of bottle body 1. The sealed cavity 201 is used to store additives such as honey. The connecting wall 202 extends radially from the outer periphery of the sealed cavity 201, achieving a smooth transition of the outer diameter from the sealed cavity 201 to the bottle body 1 through a two-stage step. The internal thread of the upper section of the connecting wall matches the external thread of the first bottle opening 102, forming a sealed fit after screwing. The bottom of storage bottle 2 adopts a thin-walled structure for easy puncture.

[0030] The lower end of the piercing element 3 is provided with a conical piercing head. Four second transmission bosses 301 are evenly distributed around the outer periphery of the piercing element 3. Each second transmission boss 301 has a second abutment surface 301a parallel to the axis and an inclined second transmission ramp 301b. A circumferentially arrayed elastic guide groove 302 is provided below the piercing element 3, with one groove opening having an inlet angle 302a. The inner wall of the sealing cavity 201 has an axial limiting ridge 204 corresponding to the guide groove 302, and the axial limiting ridge 204 has a guide ramp 204a corresponding to the inlet angle 302a.

[0031] The inner cover 4 is provided with an annular guide wall 401, and the inner circumference of the annular guide wall 401 is provided with four first transmission bosses 402, which correspond one-to-one with the second transmission bosses 301 of the puncturing member 3. The first transmission bosses 402 have a first abutment surface 402a and a second transmission inclined surface 301b. The first abutment surface 402a and the second abutment surface 301a are in clearance fit, and the first transmission inclined surface 402b and the second transmission inclined surface 301b have the same inclination angle to ensure smooth sliding.

[0032] The bottom of the outer cover 5 has a flexible snap-fit ​​protrusion 501, which can be detachably connected by snapping with the inner cover 4.

[0033] During assembly, first screw the storage bottle 2 onto the bottle body 1, then fill with the additive. Next, insert the piercing element 3 into the sealed cavity 201 of the storage bottle 2, ensuring that the axial limiting edge 204 and the guide groove 302 initially engage. Screw the inner cap 4 into the sealed position. During this process, the first abutting surface 402a pushes the second abutting surface 301a, causing the piercing element 3 to rotate. The guide groove 302 can undergo elastic deformation under the action of the guide angle 302a and the guide slope 204a, allowing it to smoothly pass over the limiting edge and enabling the piercing element 3 to rotate normally. At the same time, after the inner cap 4 is screwed closed, at least one set of guide grooves 302 and the limiting edge maintain a sliding engagement to maintain axial guidance. Finally, fasten the outer cap 5 onto the outside of the inner cap 4 to complete the overall assembly.

[0034] When using, remove the outer cap 5 and unscrew the inner cap 4. During the process, the first transmission inclined surface 402b and the second transmission inclined surface 301b slide into contact and generate an axial component force, which pushes the piercing part 3 to move downward along the axial limiting edge 204. The piercing head pierces the bottom of the storage bottle 2, and the additive flows into the receiving cavity 101 of the bottle body 1. After shaking well, it is ready to drink.

[0035] Example 2, Example 3

[0036] Reference Figure 3-5 The structures of Examples 2 and 3 are the same as those of Example 1, except that the height of the connecting wall 202 of the storage bottle 2 is different from that of Example 1. Therefore, the overall appearance is also different.

[0037] Finally, it should be noted that although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
