[0002] There are various types of cosmetic bottles on the market, but their shapes and structures are generally similar. Generally, they include a bottle body and a bottle cap. When filling cosmetics, the bottle cap is usually opened from the top for filling, and then film sealing and bottle cap installation are carried out. This filling method has a small amount of cosmetic filling. Therefore, it is necessary to design a cosmetic bottle that can increase the filling amount. Content of the Utility Model
[0003] The purpose of this application is to provide an inverted filling cosmetic bottle structure to solve the problems raised in the above background art.
[0004] To achieve the above purpose, this application provides the following technical solution: An inverted filling cosmetic bottle structure includes a bottle body, a top cover, a bottom cover, a sealing gasket, and a pressing seat. The top cover is installed at the top end of the bottle body, the bottom cover is installed at the bottom end of the bottle body. A cosmetic cavity is provided inside the bottle body. The upper and lower ends of the cosmetic cavity are open. A sealing gasket is provided at the bottom end of the cosmetic cavity to seal it. A pressing seat is provided at the bottom end of the bottle body to press the sealing gasket. The bottom cover covers the pressing seat inside it. A cosmetic injection port penetrating the inner and outer sides of the bottom end is provided at the center of the bottom end of the bottom cover. A through hole penetrating the upper and lower ends is provided on the pressing seat. The through hole and the cosmetic injection port are coaxial.
[0005] Preferably, clamping ports are fixedly installed at both the upper and lower ends of the annular convex platform on the outer side of the bottle body. The top cover and the bottom cover are respectively adapted and clamped with the corresponding clamping ports.
[0006] Preferably, a threaded interface is provided on the outer side of the bottom end of the cosmetic cavity. The pressing seat is threadedly connected to the threaded interface.
[0007] Preferably, the sealing gasket is made of elastic foam or silicone material.
[0008] In summary, the technical effects and advantages of the utility model are as follows:
[0009] The inverted filling cosmetic bottle structure provided by the utility model can pierce a puncture tube for injecting cosmetics from the cosmetic injection port at the bottom. The puncture tube pierces the sealing gasket and enters the cosmetic cavity for inverted filling, so that more cosmetics can be injected. Description of the Drawings

[0014] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.
[0015] In the description of the present disclosure, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", "top", "bottom", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present disclosure and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present disclosure. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.
[0016] It should also be noted that the standard parts used in this application document can all be purchased from the market, and can also be customized according to the descriptions in the specification and drawings. Unless otherwise clearly specified and limited, the terms "installation", "connection", and "linkage" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in this disclosure can be understood according to specific circumstances. And when there is no clear limitation, the machinery, parts, and equipment can all adopt the conventional models in the prior art.
[0017] In this article, the term "comprising" is intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements not only includes those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such a process, method, article, or device.
