Description

Technical Field

[0001] This invention relates to fluid containers for fluids, such as cosmetic formulations. Background Technology

[0002] Fluid containers are typically used to hold cosmetic formulations or other fluids.

[0003] A typical fluid container consists of a hollow bottle (usually made of plastic) containing a cosmetic preparation and a cap fixed to the bottle. In existing technology, the cap is secured to or detached from the bottle using methods such as screws, which requires a certain amount of force and is inconvenient for the user. Another method is to snap the cap onto the bottle using a non-threaded connection, which still requires a certain amount of force.

[0004] Therefore, there is a need for an improved fluid container that allows the cap to be opened in an easy manner. Summary of the Invention

[0005] The purpose of this invention is to provide a fluid container that allows for easier opening of the bottle cap.

[0006] According to an embodiment, a fluid container is provided, including a hollow bottle body and a cap, the cap being snapped onto the bottle body in a non-threaded manner, characterized in that the cap is rotatable relative to the bottle body in a rotational direction about the longitudinal axis of the container, and the cap is configured such that as the cap rotates, the bottle body is released from the cap.

[0007] According to a specific embodiment, as the bottle cap rotates relative to the bottle body, the bottle cap is deflected outward by the bottle body and pushed vertically upward by the bottle body. As a result, the bottle body is released from the bottle cap.

[0008] According to a specific embodiment, the bottle body has a rib-like structure, and the bottle cap has a corresponding hook-like structure. The hook-like structure cooperates with the rib-like structure, and when the bottle cap rotates relative to the bottle body, the hook-like structure can slide through the rib-like structure of the bottle body. Specifically, the rib-like structure of the bottle body includes a plurality of continuous ribs distributed along the circumferential direction of the bottle body, and the hook-like structure of the bottle cap includes a corresponding number of hooks distributed along the circumferential direction of the bottle cap. Each hook is positioned in a groove defined between a corresponding pair of adjacent ribs in the rib-like structure of the bottle body.

[0009] According to a specific embodiment, 3, 4, or 6 protruding ribs and hooks are provided, which are evenly distributed along the circumferential direction.

[0010] According to a specific embodiment, each rib of the bottle body has an isosceles triangle structure, including a vertex, a base, and a pair of isosceles sides. Each rib of the bottle body is configured such that each isosceles side is obliquely cut, causing it to taper radially outward, for example, at an angle of 1-89°. Similarly, each hook of the bottle cap has an inverted isosceles triangle structure, including a base and a pair of isosceles sides. Each hook of the bottle cap is configured such that each isosceles side is obliquely cut, causing it to taper radially inward, for example, at an angle of 1-89°. Preferably, the ribs of the bottle body also taper outward. This arrangement facilitates guiding the outward deformation of the hooks during bottle cap rotation.

[0011] Preferably, the ribs of the bottle body and the hooks of the bottle cap are arranged such that each pair of adjacent ribs and hooks are symmetrical to each other.

[0012] According to a specific embodiment, the bottle body has a positioning stop located above the protruding rib of the bottle body, and the bottle cap has a positioning stop located above the protruding rib of the bottle body. When the bottle body and the bottle cap are fixed to each other, the bottle cap abuts against the positioning stop of the bottle body with a first length, which is, for example, 0.1-2 mm.

[0013] Preferably, the ribs of the bottle body are arranged such that the outermost radial point of the rib is located radially outside the hook of the bottle cap at a second distance, for example, 0.1-3 mm. This second distance can be equal to or greater than the first length. With this arrangement, the hook can be bent outwards sufficiently to open the bottle cap smoothly.

[0014] Preferably, the positioning stop of the bottle body has a beveled top side and a flat bottom side, and the positioning stop of the bottle cap has a flat top side and a beveled bottom side, with the top side of the positioning stop of the bottle cap abutting against the bottom side of the positioning stop of the bottle body. This arrangement allows the bottle cap to be easily snapped onto the bottle body.

[0015] According to a specific embodiment, the container further includes a plug located on the edge of the bottle opening and extending into the bottle body. For example, the plug has an annular rib that engages with the inner wall of the bottle body.

[0016] According to a specific embodiment, the container also includes a gasket pressed between the plug and the cap. With this arrangement, the cap can be securely fastened to the bottle body.

[0017] According to this invention, opening the bottle cap can be done simply and quickly by rotating it a small angle, such as a few degrees. Furthermore, filling containers are easier because the cap can be easily snapped onto the bottle at the end of the filling production line. Fastening the cap is much easier and more secure than screwing it on. Attached Figure Description

[0036] In the context of this utility model, for convenience, directional terms such as "top", "bottom" or similar terms are used with reference to the orientation described in the figures.

[0037] Figure 1A-1C A fluid container 1 according to an embodiment of the present invention is shown. Figure 2A-4B The various components of the fluid container are described in detail.

[0038] like Figure 1A-1C As shown, the fluid container 1 includes a cap 10, a hollow bottle body 20, a plug 30, and a gasket 40. The plug 30 is located on the edge of the bottle opening and extends into the bottle body 20 to engage with the inner wall of the bottle body 20. The gasket 40 is pressed between the plug 30 and the cap 10. Furthermore, the cap 10 is rotatable relative to the bottle body 20 in a direction of rotation about the longitudinal axis of the container. The cap 10 cooperates with the bottle body 20 such that as the cap 10 rotates, the bottle body 20 is released from the cap 10, thereby enabling the cap 10 to be opened. As the cap 10 rotates, the cap 10 can be deflected outward by the bottle body 20, and optionally, it can also be pushed vertically upward by the bottle body 20.

[0039] Figures 2A-2F The bottle cap 10 is described in detail. Figure 2A This is the front view, showing details of bottle cap 10. Figure 2B It is along Figure 2A A cross-sectional view of bottle cap 10 taken from line AA. Figure 2C It is along Figure 2B A cross-sectional view of bottle cap 10 taken from line BB. Figure 2D yes Figure 2C Enlarged view of the part circled in the middle. Figure 2E yes Figure 2B A magnified view of the circled area, and Figure 2F yes Figure 2ABottom perspective view of bottle cap 10.

[0040] As shown in the figure, the bottle cap 10 is a hollow cylindrical structure consisting of an outer shell 11 and an inner portion 12 having an upper part 13 and a lower hook-like structure 14. The lower hook-like structure 14 includes a plurality of hooks 14a spaced apart from each other along the circumferential direction of the bottle cap 10 and capable of outward deflection. The inner portion 12 extends downward from the top of the outer shell 11. The downward extension of the inner portion 12 is less than the downward extension of the outer shell 11. Furthermore, an annular positioning stop 15 is provided on the inner circumferential surface of the upper portion 13 so as to abut against the corresponding positioning stop 25 of the bottle body 20 when assembled onto the bottle body 20.

[0041] like Figure 2B As shown, the positioning stop 15 has a flat top side and a beveled bottom side, thereby facilitating engagement between the positioning stop 15 of the cap 10 and the corresponding positioning stop 25 of the bottle body 20 when the cap 10 is assembled onto the bottle body 20 through a simple snap-fit ​​action.

[0042] In this example, the hook structure 14 has four hook portions 14a, which are evenly distributed along the circumferential direction, and the hook portions 14a are symmetrically arranged about the longitudinal axis of the bottle cap 10. Figure 2E As best shown, each hook 14a has an isosceles triangular structure, including a base and a pair of isosceles sides. Furthermore, as... Figure 2D As shown, each hook 14a is configured such that each isosceles side is beveled, causing it to taper radially inward, thereby forming an angle a1 in the range of 1-89 degrees, which facilitates engagement between the hook 14a of the cap 10 and the corresponding rib 24a of the bottle body 20 during assembly.

[0043] Figures 3A-3F The bottle body 20 is described in detail. Figure 3A This is a front view of bottle 20. Figure 3B for Figure 3A Enlarged view of the part circled in the middle. Figure 3C For the bottle body 20 rim Figure 3A A cross-sectional view taken from line BB. Figure 3D For the bottle body 20 rim Figure 3C A cross-sectional view taken from line CC. Figure 3E for Figure 3D Enlarged view of the part circled in the middle. Figure 3F for Figure 3A A perspective view of bottle 20 in the image.

[0044] As shown in the figure, the bottle body 20 is a hollow cylindrical structure composed of a narrow neck 21, a conical portion 22, and a larger main portion 23. The neck 21 extends downward through the conical portion 22 to the main portion 23. Furthermore, a rib structure 24 is provided in the bottle body 20. The rib structure 24 includes multiple protruding ribs 24a (four in this example), which are evenly distributed and continuous with each other in the circumferential direction of the bottle body. The protruding ribs 24a extend upward from the conical portion 22 along the neck 21. Additionally, an annular positioning stop 25 is provided on the outer peripheral surface of the neck 21, located above the protruding ribs 24a.

[0045] In this example, each rib 24a is arranged symmetrically about the line of symmetry, and all ribs 24a are arranged symmetrically about the longitudinal axis of the bottle body 20. For example... Figure 3B As best shown, each rib 24a has an isosceles triangular structure, including a vertex, a base, and a pair of isosceles sides. The ribs 24a are continuous with each other at their respective bases. Furthermore, as... Figure 3E As shown, each rib 24a is configured such that each isosceles side is beveled, such that it tapers radially outward at an angle a2, which can be in the range of 1-89 degrees, thereby facilitating engagement between the hook 14a of the cap 10 and the corresponding rib 24a of the bottle body 20 during assembly.

[0046] like Figure 3C As shown in the best embodiment, the positioning stop 25 has a beveled top side and a flat bottom side, thereby facilitating the abutment between the positioning stop 25 of the bottle body 20 and the corresponding positioning stop 15 of the bottle cap 10 when the bottle body 20 is assembled onto the bottle cap 10 through a simple snap-fit ​​action.

[0047] In addition, such as Figure 3B As shown in the optimal configuration, the rib 24a tapers upwards. As a result, during the rotation of the bottle cap 10, as the hook portion 14a of the bottle cap 10 slides past the rib 24a, the hook portion 14a of the bottle cap 10 is pushed vertically upwards by the rib 24a, thereby facilitating the separation of the bottle body 20 from the bottle cap 10.

[0048] Figures 4A-4B The plug 30 is described in detail. As shown in the figure, the plug 30 has a hollow cylindrical basic shape including a flat top side, a shell, and a downwardly extending inner boss 33. The inner boss is slightly tapered downward and has an opening 32 therein to define the opening of the plug 30. The top side rests on the edge of the bottle mouth of the bottle body 20 (see...). Figure 1B ).

[0049] The plug 30 has annular ribs 31 (two ribs in this example) disposed on the outer peripheral surface of the plug 30 housing, for engaging with the inner wall of the bottle body 20 via a snap-fit ​​connection. In this example, the ribs 31 are continuous in the circumferential direction. However, they are not necessarily continuous.

[0050] In addition, such as Figure 1B As shown, the flat top side of the positioning stop 15 of the bottle cap 10 abuts against the flat top side of the positioning stop 25 of the bottle body 20, with an abutment length of d1 (in this example, d1 = 0.1-2 mm). This length facilitates the engagement and disengagement of the positioning stops 15 and 25. Furthermore, as... Figure 1B As shown in the optimal configuration, the outermost radial point of the rib 24a is positioned radially beyond the hook 14a by an additional distance d2 (in this example, d2 = 0.1-3 mm, the same as or greater than d1). Thus, as the hook 14a slides past the rib 24a and is therefore deflected outwards, the abutment length gradually decreases to zero, causing the rib 24a and the hook 14a to no longer abut against each other. As a result, the cap 10 and the bottle body 20 are released from each other.

[0051] The bottle cap opening action proceeds as follows. Each component 14 of the bottle cap 10 is initially positioned in a groove 24b defined between a corresponding pair of ribs 24a on the bottle body 20. The user can grasp the bottle cap 10 and rotate it by only a small angle. As the bottle cap 10 rotates, its hook 14a slides over the ribs 24a, and due to the beveled structure on both sides of the ribs 24a and the hook 14a, the ribs 24a then deflect the hook 14a outward. At the same time, due to the tapered structure of the ribs 24a, the hook 14a is also pushed vertically upward. Thus, the positioning stop 15 of the bottle cap 10 no longer abuts against the positioning stop 25 of the bottle cap 10, allowing the bottle body to release from the cap and pop out of it. Then, due to the oblique cut structure of the positioning stops 15 and 25, the positioning stops 15 and 25 can be re-engaged by a snap-fit ​​action, causing each hook 14a of the bottle cap 10 to return to its positioning in the groove 24b defined between the corresponding pair of protruding ribs 24a of the bottle body 20. Therefore, the bottle cap can be assembled onto the bottle body through a simple snap-fit ​​action.

[0052] As described above, the embodiments of this invention illustrate fluid containers for holding, for example, cosmetic formulations. However, it should be understood that this invention is also applicable to fluid containers for holding other fluids. Furthermore, the fluid containers may be refillable.
