Description

Technical Field

[0001] This application relates to the field of packaging bottle technology, and more particularly to a packaging bottle that is easy to extrude. Background Technology

[0002] Existing toothpaste storage devices are specially designed containers specifically for storing toothpaste. The opening of this device is cleverly connected to a cap via a screw-on mechanism, ensuring the toothpaste is sealed when not in use. To use the toothpaste, the user must first unscrew the cap; this simple action prepares the toothpaste to be squeezed out. While this design achieves the functions of toothpaste storage and use to some extent, the operation is inconvenient because the cap must be unscrewed before each use, making it impractical in actual use. Therefore, those skilled in the art urgently need to develop a packaging bottle that is easy to squeeze out to meet practical application needs. Utility Model Content

[0003] The main objective of this application is to provide a packaging bottle that is easy to extrude, thereby addressing the aforementioned technical problems.

[0004] To achieve the above objectives, this application proposes a packaging bottle that is easy to extrude, comprising a bottle body and a cap connected to the bottle body, wherein the cap has an extrusion channel inside, and the packaging bottle that is easy to extrude further comprises:

[0005] An outer cap is provided on the outer side of the upper end of the bottle cap, and has an internal cavity for receiving the contents, and a clearance opening at its upper end.

[0006] A one-way valve body is disposed inside the accommodating cavity, with its lower end limited by the upper end of the bottle cap and its upper end extending into the clearance opening.

[0007] The one-way valve body has an output channel inside that is connected to the extrusion channel, and a one-way output opening at its upper end.

[0008] As described above, the packaging bottle that is easy to extrude has an annular groove on the inner sidewall of the containing cavity, and also has a snap-fit ​​ring groove located on the upper side of the annular groove and recessed upward.

[0009] The upper outer side of the bottle cap is provided with an outwardly protruding annular protrusion for fitting and connecting with the annular groove.

[0010] The lower outer side of the one-way valve body is provided with an outwardly protruding annular portion, and the outwardly protruding annular portion is provided with an upwardly protruding annular protrusion for fitting and connecting with the snap-fit ​​ring groove.

[0011] The one-way valve body of the extruded packaging bottle described above is made of silicone.

[0012] As described above, the one-way valve body of the easily extruded packaging bottle is truncated cone-shaped.

[0013] The extrusion-friendly packaging bottle described above is made of a soft plastic material.

[0014] The extrusion-friendly packaging bottle described above has a spherical shape.

[0015] Compared with the prior art, the above application has the following advantages:

[0016] This application presents an extrusion-friendly packaging bottle by placing the one-way valve body within the containing cavity of the outer cap. The outer cap, incorporating the one-way valve body, can then be connected to the bottle cap. When the bottle is squeezed, the toothpaste, gel, or fluid contained within it is forced to flow into the extrusion channel, then into the output channel, and finally outwards through the one-way output opening. Conversely, when the bottle is not subjected to external pressure, the one-way valve body remains closed, preventing the output of toothpaste, other gels, or fluids. This not only facilitates quantitative extrusion of the contents but also effectively prevents the common problem of toothpaste, gels, or fluids splashing out of the bottle opening during extrusion, thus avoiding waste or contamination. Furthermore, the design of this application is simple and reasonable, easy to manufacture and process, and convenient to disassemble and clean, greatly improving user convenience.

[0029] like Figures 1 to 8 As shown, a packaging bottle that is easy to extrude includes a bottle body 1, a bottle cap 2, an outer cap 3, and a one-way valve body 4.

[0030] Specifically, the bottle cap 2 is connected to the bottle body 1, and an extrusion channel 21 is provided inside it; the outer cap 3 is located on the outer side of the upper end of the bottle cap 2, and a receiving cavity 31 is provided inside it, and a clearance opening 32 is provided at its upper end.

[0031] The one-way valve body 4 is located inside the accommodating cavity 31, and its lower end is limited by the upper end of the bottle cap 2, and its upper end extends into the relief opening 32; the one-way valve body 4 has an output channel 41 connected to the extrusion channel 21 inside, and a one-way output opening 42 at its upper end.

[0032] This application's easily extruded packaging bottle features a one-way valve body 4 positioned within the containing cavity 31 of the outer cap 3. The outer cap 3, with the embedded one-way valve body 4, can then be connected to the bottle cap 2. When the bottle body 1 is squeezed, the toothpaste, gel, or fluid contained within it is forced to flow through the extrusion channel 21, then to the output channel 41, and finally outwards through the one-way output opening 42. Conversely, when the bottle body 1 is not subjected to external pressure, the one-way valve body 4 remains closed, preventing the output of toothpaste, other gels, or fluids. This not only facilitates quantitative extrusion of the substances within the bottle body 1 but also effectively prevents the common problem of toothpaste, gels, or fluids splashing from the bottle opening during extrusion, thus avoiding waste or contamination. Furthermore, this application boasts a simple and reasonable structure, is easy to manufacture and process, and is convenient to disassemble and clean, greatly improving user convenience.

[0033] Furthermore, the inner sidewall of the accommodating cavity 31 is provided with an annular groove 311, and a snap-fit ​​groove 312 is provided on the upper side of the annular groove 311 and recessed upward.

[0034] The bottle cap 2 has an outwardly protruding annular protrusion 22 on the outer side of its upper end for fitting and connecting with the annular groove 311.

[0035] The lower outer side of the one-way valve body 4 is provided with an outwardly protruding annular portion 43, and the outwardly protruding annular portion 43 is provided with an upwardly protruding annular protrusion 44 for fitting and connecting with the snap-fit ​​ring groove 312. Its advantage is that it is easy to snap-fit, that is, it can not only realize disassembly and connection, but also achieve the outstanding effect of quick disassembly and quick connection.

[0036] Furthermore, the one-way valve body 4 is made of silicone. Silicone has the advantages of being exceptionally soft, hygienic, and having a long service life, thus meeting usage requirements.

[0037] Furthermore, the one-way valve body 4 is truncated cone-shaped. This is to facilitate the shaping of the conical output channel 41.

[0038] Furthermore, the bottle body 1 is made of a soft plastic material. This is to meet the requirement of being able to be squeezed.

[0039] Furthermore, the shape of the bottle body 1 is preferably spherical, in order to improve the aesthetic appeal of the application. Of course, it can also be a cylindrical, cuboid, cube, or other shapes.

[0040] The above description is one implementation method provided in conjunction with specific content, and does not imply that the specific implementation of this application is limited to these descriptions. Any methods or structures that are similar to or identical to those of this application, or any technical deductions or substitutions made based on the concept of this application, should be considered within the scope of protection of this application.
