[0029] The following is a description of exemplary embodiments of the present invention in conjunction with the accompanying drawings, including various details of the embodiments of the present invention to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for the sake of clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0030] As used herein, the term "including" and its variations mean open inclusion, i.e., "including but not limited to". Unless otherwise stated, the term "or" means "and / or". The term "based on" means "based at least in part on". The terms "an example embodiment" and "an embodiment" mean "at least one example embodiment". The term "another embodiment" means "at least one additional embodiment".

[0031] In addition, the terms "first", "second", etc. used in the present disclosure are only used to distinguish various objects for the sake of clarity of description, and do not limit the size, quantity or other order of the objects described. The orientation or position relationship indicated by directional terms is based on the orientation or position relationship shown in the drawings, which is only for the purpose of facilitating the description of the present application, and does not indicate or imply that the objects referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present application.

[0032] In the disclosed context, unless otherwise specified, “distal side” refers to the downstream side in the direction in which the liquid substance flows out of the container, and “proximal side” refers to the upstream side in the direction in which the liquid substance flows out of the container.

[0033] like Figure 1 and Figure 2 As shown, according to one embodiment of the utility model, the container 1 includes a container body 2 and a container cover 3 installed on the container body 2, the container body 2 is used to contain liquid substances, and the container cover 3 is used to allow the liquid substances to flow out of the container 1 when opened so as to be taken, and to seal the container 1 when closed to prevent the liquid substances from flowing out of the container 1.

[0034] like Figure 1 and Figure 2 As further shown, the container cover 3 includes a base 4 and a cover 5 for covering the base 4, and the cover 5 can be turned up to expose the upper surface of the base 4. The base 4 and the cover 5 can be completely separated, or can be connected together at the connection part 8 so as to be rotatable relative to each other, without limitation. Figure 1 and Figure 2In the illustrated embodiment, the base 4 and the lid portion 5 can be integrally formed, for example, integrally formed of plastic, so as to reduce the manufacturing and assembly processes and costs. It should be understood that in other embodiments not shown, the base 4 and the lid portion 5 can also be connected together by a hinge mechanism or the like.

[0035] As Figure 2 and Figure 3 shown, the base 4 can include an opening portion 6 in which a through hole is formed for the liquid substance accommodated in the container body 2 to flow out for use. As Figure 2 and Figure 3 further shown, the opening portion 6 can be configured to extend distally from the upper surface 18 of the base 4 to help avoid the liquid substance spreading on the upper surface 18 of the base 4 and causing waste of the liquid substance and contamination of the container lid 3 etc. when the use of the liquid substance is completed.

[0036] As Figures 3 to 5 shown, the lid portion 5 can include a lid portion main body 19 and a plug portion 7. The plug portion 7 is used to tightly fit with the through hole formed in the opening portion 6 when the container lid 3 is in the closed state to achieve the sealing of the container lid 3 and the container 1 and prevent the liquid substance in the container body 2 from flowing out. For example, as Figure 4 and Figure 5 shown, the plug portion 7 can be integrally formed with the lid portion main body 19 to form the lid portion 5, which helps to reduce the manufacturing and assembly processes and costs. It should be understood that in other embodiments not shown, the plug portion 7 can also be separately formed from the lid portion main body 19 and assembled together, for example, by bonding, snap - fitting and other processes, so that the respective materials of the plug portion 7 and the lid portion main body 19 can be selected according to needs, improving the flexibility of the structure of the lid portion 5.

[0037] Figure 3 Shows Figure 1 and Figure 2 a perspective view of the container lid 3 of the container 1 in Figure 4 and Figure 6 , where the lid portion 5 of the container lid 3 is in the open state. Combining

[0038] The axial directions of the through-hole in the opening portion 6 and the plug portion 7 can be set to be substantially parallel to the height direction of the container 1, which is beneficial for taking the liquid substance inside the container 1 when the container 1 is inverted, and guiding the reflux of the liquid substance when the container 1 is upright after taking the liquid substance. It should be understood that in other embodiments not shown, the axial directions of the through-hole in the opening portion 6 and the plug portion 7 can also be set to form a certain angle with the height direction of the container 1 respectively, as long as the through-hole and the plug portion 7 can be aligned and cooperate to form a seal.

[0039] As Figure 3 shown, the opening portion 6 can be positioned at the central position in the upper surface 18 of the base 4, and the positioning of the plug portion 7 in the lid portion 5 matches the position of the opening portion 6. Such positioning of the opening portion 6 and the plug portion 7 facilitates manufacturing. It should be understood that in other embodiments not shown, the opening portion 6 can also be positioned at a position offset from the central position in the upper surface 18 of the base 4. Thus, when the remaining amount of the liquid substance in the container body 2 is not much, the user can take the remaining part of the liquid substance by tilting the container body 2 accordingly, thereby avoiding the problem that the last small amount of the remaining liquid substance is difficult to take out. For example, the opening portion 6 can be positioned at a side away from the connecting portion 8 relative to the central position in the upper surface 18 of the base 4, which is convenient for positioning during manufacturing and also helps to avoid or reduce the situation where the liquid substance undesirably drips onto the lid portion 5 due to the insufficient opening angle of the lid portion 5 when taking the liquid substance in the container body 2.

[0040] As Figure 6 more clearly shown in, in some embodiments, the inner diameter a of the sealing segment 11 can be set to 1.2 mm or less. For example, it can be set to 0.8 mm to 1.2 mm, which helps to accurately control the outflow of the liquid substance during the outflow process of the liquid substance, so that the liquid substance can flow out of the opening portion 6 through the sealing segment 11 in a drop-by-drop manner, enabling the user to accurately take the liquid substance as needed, avoiding or reducing splashing, waste and other situations, and improving the user experience. In some embodiments, the inner diameter b of the distal end of the extension segment 12 can be set to 4 mm to 5 mm, and the length c in the axial direction of the opening portion 6 can be set to 2.5 mm to 3 mm. Such an aspect ratio helps to guide the reflux of the liquid substance and avoid or reduce the liquid substance flowing to the radial outside of the opening portion 6.

[0041] In some embodiments, when the plug portion 7 and the sealing segment 11 cooperate, the contact length between them in the axial direction of the opening portion 6 can be set to 0.6 mm to 1.0 mm, which helps to ensure the sealing performance between them while taking into account the strength of the plug portion 7 and avoiding the risk of the plug portion 7 breaking due to being too long. In addition, asFigure 3 As shown, the cover portion 5 may further include a plurality of reinforcing ribs 15 that surround and are integrally provided with the plug portion 7 to further improve the strength of the plug portion 7 and prevent it from breaking. Further, as Figures 3 to 5 shown, the cover portion 5 may also include a reinforcing wall 16 that surrounds and is spaced apart from the plug portion 7. The reinforcing wall 16 is arranged to surround the outer peripheral edge of the distal end portion of the opening portion 6 when the cover portion 5 is in the closed state, thereby helping, for example, when the container 1 or the container cover 3 is impacted, to buffer through the interaction with the opening portion 6 and reduce the risk of breakage at the plug portion 7, the connecting portion 8, etc.

[0042] As Figure 6 shown, in the axial direction of the opening portion 6, the expansion section 12 may include a diversion section 13 located distally and a buffer section 14 located proximally to the diversion section 13. Among them, the inner diameter change rate of the diversion section 13 in the axial direction of the opening portion 6 is greater than the inner diameter change rate of the buffer section 14 in the axial direction of the opening portion 6. Through such an arrangement, it helps the liquid substance to quickly fall back at the diversion section 13, and at the same time ensures a certain volume at the buffer section 14 to appropriately slow down the falling of the liquid substance at the buffer section 14, thereby reducing or avoiding the possibility of generating bubbles at the sealing section 11.

[0043] As Figure 6 shown, the through hole in the opening portion 6 may further include a guiding section 17 that extends proximally starting from the sealing section 11, and the inner diameter of the guiding section 17 is smaller than the inner diameter of the sealing section 11. By providing the guiding section 17, it can further help to accurately control the flow rate of the liquid substance when the container 1 is inverted for the liquid substance to flow out, and help to avoid or reduce the situation where when the liquid substance in the container 1 is filled relatively full, when the container 1 is shaken or impacted and the cover portion 5 is in the open state, the liquid substance undesirably overflows from the container 1. In some embodiments, the inner diameter d of the guiding section 17 is, for example, 0.6 mm to 0.8 mm, and the length e of the guiding section 17 in the axial direction of the opening portion 6 is, for example, 0.4 mm to 0.6 mm, so as to be able to achieve accurate control of the flow rate of the liquid substance when reducing or avoiding the undesired overflow of the liquid substance, and at the same time be able to accurately control the flow rate of the liquid substance when taking it.

[0044] From the above description, it can be known that the container cover 3 and the container 1 according to the present utility model can help to accurately control the outflow rate of the liquid substance when taking the liquid substance inside the container 1, and when the taking of the liquid substance is completed, it can help to effectively guide the reflux of the liquid substance into the container 1, thereby being able to avoid or reduce the occurrence of waste, pollution, etc., and improve the use experience.

[0045] The present utility model has been described through the above embodiments. However, it should be understood that the above embodiments are only for illustrative and explanatory purposes, and are not intended to limit the present disclosure to the scope of the described embodiments. Those skilled in the art should understand that more variations and modifications can be made according to the teachings of the present disclosure, and these variations and modifications all fall within the protection scope of the present disclosure. It should be noted that the features or combinations of features according to the present disclosure described above, as well as the features and combinations of features mentioned in and / or only shown in the drawings, can not only be used in combination with the corresponding combinations given, but also be used in other combinations or alone without departing from the scope of the present disclosure.
