Description

Technical Field

[0001] This utility model relates to the field of packaging container technology, and more specifically, to a bottle mouth mechanism for a packaging bottle. Background Technology

[0002] Packaging bottles are a type of packaging container in the packaging industry. They generally refer to containers with a narrower mouth than body and a longer neck. The capacity of packaging bottles generally ranges from 100 milliliters to several liters. Most packaging bottles are made of materials that are not easily leaked, such as ceramics, glass, plastics, or metals.

[0003] However, existing technologies offer a variety of bottle opening types. For example, utility model patent CN202321258U relates to an improved beverage bottle opening. This utility model includes a bottle opening body with a screw-in cap thread. The bottle opening body is 17mm high, and the screw-in cap thread encircles the bottle opening body twice. With this structure, the bottle opening of the beverage packaging bottle can maintain the sealing effect of the original hot-fill packaging while reducing the bottle opening weight to below 3.8 grams. This achieves the goal of saving plastic raw materials and reducing product packaging costs while maintaining the various performance characteristics of the beverage packaging bottle.

[0004] While this packaging bottle opening ensures a tight seal and reduces product packaging costs, it uses a leak-proof spiral structure for sealing. However, opening the bottle is difficult and time-consuming, making it inconvenient to use. To avoid this, designing a bottle opening mechanism is essential. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] To achieve the above objectives, this utility model provides a bottle mouth mechanism for a packaging bottle, which is accomplished by the following specific technical means:

[0007] A bottle neck mechanism for a packaging bottle includes a bottle neck body disposed on the packaging bottle body. A sealing soft plug is embedded in the top of the bottle neck body. A positioning ring is coaxially disposed on the outer surface of the bottle neck body. Two grooves are formed at the circumferential edge of the positioning ring. Two limiting blocks are fixedly connected to the bottom of the positioning ring. A sealing cap is sleeved on the outside of the bottle neck body. Two snap-fit ​​seats are fixedly connected to the bottom of the sealing cap, and the two snap-fit ​​seats are symmetrically arranged. The snap-fit ​​seats match the grooves. Multiple symmetrical insertion holes are formed on the top of the sealing cap.

[0008] Preferably, the inner diameter of the sealing cap is larger than the outer diameter of the positioning ring, and the two grooves are arranged symmetrically. The sealing cap is pressed against the sealing soft plug so that the two snap-fit ​​seats pass through the matching grooves, and then the sealing cap is rotated so that the two snap-fit ​​seats are locked at the bottom of the positioning ring.

[0009] Preferably, a fixing post is provided at the top center of the sealing soft stopper, and multiple anti-slip protrusions are provided on the surface of the fixing post. A through hole is opened at the top of the sealing cap, and the through hole is located in the middle of the two insertion holes. The fixing post passes through the through hole.

[0010] Preferably, the top of the sealed bottle cap is provided with an installation sleeve, and the bottom of the installation sleeve is fixedly connected with two symmetrical positioning posts, which can be embedded inside the insertion hole.

[0011] Preferably, the mounting sleeve has a mating circular hole, and the fixing post extends into the mating circular hole so that the anti-slip protrusion abuts against the mounting sleeve.

[0012] Preferably, a flow guide ear is provided at the outer edge of the bottle mouth body, and the flow guide ear is annular. Two symmetrical leakage grooves are provided through the bottle mouth body, and the leakage grooves are located below the flow guide ear.

[0013] Preferably, a collection shell is provided on the outer surface of the bottle mouth body, and the collection shell is annular. When the sealing soft plug is embedded in the interior of the bottle mouth body, the sealing soft plug can abut against the collection shell to seal the leakage groove.

[0014] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0015] During the sealing process of the bottle opening, a sealing soft stopper is embedded into the bottle opening body to initially seal the bottle opening. Then, the sealing cap is placed on the bottle opening, and the positioning ring is embedded in the sealing cap so that the locking seat passes through the matching groove. The sealing cap is then screwed a quarter turn, and the two locking seats hook the positioning ring, pressing the sealing soft stopper tightly with the sealing cap, thus achieving the purpose of preventing leakage. When unscrewing the cap, simply screw the sealing cap in the opposite direction to open it. Compared with the traditional anti-leakage spiral structure, it saves time and effort, making the packaging bottle more convenient to use. Attached Figure Description

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0025] like Figure 1 , Figure 3As shown, this is a schematic diagram of the bottle neck mechanism of the packaging bottle in this embodiment. The bottle neck mechanism in this embodiment includes a bottle neck body 1, which is disposed on the packaging bottle. A sealing soft plug 2 is embedded in the top of the bottle neck body 1. A positioning ring 3 is coaxially disposed on the outer surface of the bottle neck body 1. Two grooves 4 are formed at the circumferential edge of the positioning ring 3. Two limiting blocks 5 are fixedly connected to the bottom of the positioning ring 3. A sealing bottle cap 6 is sleeved on the outside of the bottle neck body 1. Two snap-fit ​​seats 7 are fixedly connected to the bottom of the sealing bottle cap 6, and the two snap-fit ​​seats 7 are arranged symmetrically. In the process of sealing the packaging bottle neck, the sealing soft plug 2 is first embedded in the bottle neck body 1. Inside the body 1, the bottle opening is initially sealed. Then, the sealing cap 6 is placed on the bottle opening. The positioning ring 3 will embed into the sealing cap 6 so that the two locking seats 7 pass through the matching grooves 4. After the locking seats 7 pass through the grooves 4, the sealing cap 6 is turned a quarter turn so that the locking seats 7 abut against one side of the limiting block 5. The two locking seats 7 hook the positioning ring 3, and the sealing cap 6 presses the sealing soft stopper 2, thereby achieving the purpose of preventing leakage. When unscrewing the cap, simply turn the sealing cap 6 in the opposite direction to unscrew it. Compared with the traditional anti-leakage spiral structure, it saves time and effort, making the packaging bottle more convenient to use.

[0026] It is worth noting that in this embodiment, the inner diameter of the sealing cap 6 is larger than the outer diameter of the positioning ring 3, the two grooves 4 are arranged symmetrically, and the snap-fit ​​seat 7 matches the groove 4.

[0027] like Figure 2 As shown, this is a schematic diagram of the structure inside the mounting sleeve 11 in this embodiment. In this embodiment, the top of the sealing bottle cap 6 is provided with multiple symmetrical insertion holes 8, and the top center of the sealing soft plug 2 is provided with a fixing post 9. The surface of the fixing post 9 is provided with multiple anti-slip protrusions 10. The top of the sealing bottle cap 6 is provided with a through hole, and the through hole is located in the middle of the two insertion holes 8. The fixing post 9 passes through the through hole.

[0028] In this embodiment, the top of the sealing cap 6 is provided with an installation sleeve 11. The bottom of the installation sleeve 11 is fixedly connected with two symmetrical positioning posts 13, and the positioning posts 13 can be embedded in the interior of the insertion hole 8. The installation sleeve 11 is provided with a mating round hole 12, and the fixing post 9 extends into the mating round hole 12 so that the anti-slip protrusion 10 abuts against the installation sleeve 11. When the sealing cap 6 is pressed on the sealing soft plug 2, the fixing post 9 on the sealing soft plug 2 passes through the through hole and extends to the outside of the sealing cap 6. At this time, the installation sleeve 11 is used to embed the fixing post 9 into the mating round hole 12 of the installation sleeve 11, so that multiple anti-slip protrusions 10 are squeezed into the mating round hole 12. At the same time, the positioning post 13 at the bottom of the installation sleeve 11 is inserted into the interior of the corresponding insertion hole 8. The anti-slip characteristics of the anti-slip protrusion 10 are used to fix the installation sleeve 11. Since the pressed sealing soft plug 2 is in a fixed state, the sealing cap 6 is positioned and fixed by the inserted positioning post 13, thereby limiting the screw-on sealing cap 6.

[0029] like Figure 4 As shown, this is a schematic diagram of the structure of the bottle mouth end in this embodiment. In this embodiment, a guide ear 14 is provided at the outer edge of the bottle mouth body 1, and the guide ear 14 is annular. Two symmetrical leakage grooves 16 are provided through the bottle mouth body 1, and the leakage grooves 16 are located below the guide ear 14. A collection shell 15 is provided on the outer surface of the bottle mouth body 1, and the collection shell 15 is annular. When the sealing soft plug 2 is embedded in the interior of the bottle mouth body 1, the sealing soft plug 2 can abut against the collection shell 15 to seal the leakage grooves 16. During the process, the liquid is poured out from the bottle mouth body 1. After the liquid is poured out, it will stick to the bottle mouth. The liquid can flow along the surface of the guide ear 14 through the guiding effect of the guide ear 14. The suspended liquid will flow into or drip into the collection shell 15. Through the guiding effect of the collection shell 15, the collected liquid is guided into the leakage tank 16, so that the liquid stuck to the wall flows back into the packaging bottle through the leakage tank 16. This prevents the liquid stuck to the wall from flowing down the outer wall and avoids the packaging bottle from being easily contaminated.

[0030] 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.
