Description

Technical Field

[0001] This utility model relates to the field of packaging containers, and more particularly to a packaging bottle. Background Technology

[0002] With the continuous increase in market demand, various types of outer packaging have also increased. In the pharmaceutical, food, and daily chemical product industries, liquid or paste-like products are often packaged in bottles with a threaded connection between the can and the cap. The bottles are usually sealed with detachable caps to prevent leakage.

[0003] However, when using this type of packaging bottle with a separate can and cap, the cap needs to be unscrewed to remove the material, which is inconvenient and the disassembled cap is easy to lose. Secondly, when screwing the cap back on, improper fit between the cap and the can often occur, resulting in poor sealing and leakage.

[0004] Therefore, this utility model provides a new technical solution to solve the above problems. Utility Model Content

Detailed Implementation

[0028] 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.

[0029] This embodiment discloses a packaging bottle, as shown in the following figure. Figures 1 to 8 As shown, it mainly includes a tank body 1, an inner cover 2, an outer cover 3, and a sealing element 4. The tank body 1 includes a tank opening 11. The sealing element 4 is nested and installed on the inner cover 2. The inner cover 3 is installed on the tank opening 11. The outer cover 3 is fitted around the outer periphery of the inner cover 2 and can be rotated and adjusted.

[0030] Reference Figure 7 and Figure 8The sealing element 4 is made of rubber or silicone and is integrally molded with the inner cover 2. The sealing element 4 is mainly composed of sealing ring 41 and sealing ring 42. The sealing ring 41 and sealing ring 42 are connected by a connecting part 43 and integrally molded. A through hole 22 is provided on the outer wall of the inner cover 2. The sealing element 4 is embedded in the inner cover 2. The connecting part 43 passes through the through hole 23 to integrally connect the sealing ring 41 and sealing ring 42. The connecting part 43 can close the through hole 22.

[0031] Reference Figure 3 and Figure 4 As shown, the inner cover 2 is threaded to the can opening 11 and sealed by a sealing ring 41. The sealing ring 41 is embedded in the inner circumference of the inner cover 2. The upper end face 411 of the sealing ring 41 is tightly fitted to the lower end face 29 on the inner side of the inner cover 2. The lower end face 412 of the sealing ring 41 is pressed against the end of the can opening 11, thus achieving a sealed connection between the inner cover 2 and the can body 1. An opening 21 is provided on the peripheral wall of the inner cover 2, which can communicate with the interior of the can body 1. A limiting groove 25 is provided on the outer circumference of the opening 21, and the sealing ring 42 can be embedded in the limiting groove 25. When the outer cover 3 is fitted on the outer circumference of the inner cover 2, the sealing ring 42 can be tightly fitted to the inner circumference of the outer cover 3, thus forming a seal.

[0032] Reference Figure 2 and Figure 3 As shown, an opening 21 is provided on the outer peripheral wall of the outer cover 3, and the size of the opening 21 is adapted to the opening 1. An annular protrusion 23 is provided on the inner periphery of the outer cover 3 near the bottom, and an annular protrusion 126 is provided on the outer periphery of the inner cover 2. An annular groove 27 is formed between the annular protrusion 126 and the upper end face 128 of the inner cover 2. When the outer cover 3 is fitted on the outer periphery of the inner cover 2, the annular protrusion 23 on the inner periphery of the outer cover 3 can be embedded in the annular groove 27 to form a limiting installation, so that the outer cover 3 can be axially rotated relative to the inner cover 2. By rotating and adjusting the relative position between the outer cover 3 and the inner cover 2, the connection and closure between the opening 21 on the outer cover 3 and the opening 121 on the inner cover 2 can be realized, thereby realizing the opening and closing of the tank 1. The operation is convenient, the material is easy to pick up, and it is simple and practical.

[0033] Reference Figure 3 and Figure 5As shown, a protrusion 23 is integrally connected to the outer peripheral wall of the inner cover 2 on the other side of the opening 21. The protrusion 23 is axially arranged, and the outer periphery of the protrusion 23 protrudes beyond the outer peripheral wall of the inner cover 2 integrally connected to the protrusion 23. Since the protrusion 23 is arranged relative to the opening 21 and protrudes beyond the outer peripheral wall of the inner cover 2, when the outer cover 3 is fitted onto the outer peripheral wall of the inner cover 2, the protrusion 23 can abut against the inner periphery of the outer cover 3, forming a compression on the inner wall of the outer cover 3. This allows the sealing ring 42 installed on the outer periphery of the opening 21 to fit tightly against the inner periphery of the outer cover 3, enhancing the sealing effect of the sealing ring 42 between the inner cover 2 and the outer cover 3 and preventing leakage.

[0034] Reference Figure 5 and Figure 6 As shown, when the outer cover 3 is rotated relative to the inner cover 2, it has a first position and a second position; a groove 24 is provided on the outer peripheral wall of the inner cover 2 and at the upper end of the protrusion. A limiting part 1 241 and a limiting part 242 are respectively provided on both sides of the groove 24 near the two ends. The limiting part 1 241 and the limiting part 241 are provided with oppositely arranged guide slopes on both sides to facilitate the rotational adjustment of the outer cover 3; a limiting part 32 is provided on the inner peripheral wall of the outer cover 3. The limiting part 32 is embedded in the groove 24 and can be axially rotated along the bending direction of the groove 24.

[0035] When the outer cover 3 rotates relative to the inner cover 2 to the first position, the protrusion 23 on the inner circumference of the outer cover 3 is embedded between the inner circumference of the groove 24 and the limiting part 241. At this time, the opening 21 on the inner cover 2 and the opening 31 on the outer cover 3 are connected to the inside of the tank 1, and the material contained in the tank 1 can be poured out and taken out. When the outer cover 3 rotates relative to the inner cover 2 to the second position, the protrusion 23 on the inner circumference of the outer cover 3 is embedded between the inner circumference of the groove 24 and the limiting part 242, so that the opening 31 and the opening 21 are staggered. The inside of the outer cover 3 covers the opening 21 and is sealed by the sealing ring 42. The tank 1 is closed, ensuring that the material contained in the tank 1 is sealed and stored.

[0036] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
