[0056] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art.

[0057] In this document, the terms “upper,” “lower,” “inner,” and “outer,” etc., which indicate orientation or positional relationships, are defined with reference to the direction observed by the user when using the cosmetic container. They are used only for the convenience of describing this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0058] Figures 1 to 22 The diagrams are drawn to scale. To keep the instructions concise, the proportions of each component are not listed individually. However, the proportions and positions of each component should be considered part of the contents of this instruction manual.

[0059] See Figures 1 to 22 The illustrated spreadable packaging container includes a bottle 1 for containing cosmetics and a cosmetic application device connected to the bottle 1. The cosmetics in the bottle 1 can be applied to body parts through the application device to achieve makeup application.

[0060] The applicator includes:

[0061] Mounting base 3 is used to connect with bottle body 1. Specifically, bottle body 1 has a bottle mouth 11 located at the top. The outer periphery of the bottle mouth 11 is provided with external threads. Mounting base 3 is sleeved on the bottle mouth 11 and threadedly connected to the bottle mouth 11 to realize a detachable connection with bottle body 1.

[0062] The applicator head 5 is fixedly mounted on the upper part of the mounting base 3. The applicator head 5 has a discharge hole 51 for the cosmetic to pass through. The cosmetic flows out of the applicator head 5 through the discharge hole 51 and can then be evenly applied to the user's body through the applicator head 5.

[0063] The applicator 4 is axially inserted into the bottle body 1, and its upper part is fixedly connected to the mounting base 3.

[0064] The upper part of the applicator 4 has an axially extending feed channel 42, which extends through to the top of the applicator 4 and communicates with the discharge hole 51. The side of the applicator 4 is also provided with a feed hole 41, which communicates with the feed channel 42.

[0065] In this way, the cosmetics in the bottle 1 can enter the feed channel 42 through the feed hole 41, and then flow out through the discharge hole 51 of the application head 5 for use. Users can use cosmetics for application without removing the application device from the bottle 1, that is, while keeping the mounting base 3 connected to the bottle 1, which makes it convenient for cosmetic use.

[0066] The applicator can also have an applicator component (not shown in the figure) installed in the lower part of the bottle body 1 where the applicator rod 4 is inserted. The user can also remove the mounting base 3 from the bottle body 1 as needed, thereby removing the applicator rod 4 from the bottle body 1 and using the cosmetics picked up by the applicator component at the lower part of the applicator rod 4.

[0067] Referring to the accompanying drawings, the packaging container also includes an inner plug 6, which fits into the bottle opening 11. When the applicator rod 4 is inserted into the bottle body 1, it also fits into the inner plug 6 to prevent the cosmetic bottle in the bottle body 1 from leaking out. The feed hole 41 on the applicator rod 4 is located below the inner plug 6 to ensure that the cosmetic in the bottle body 1 can enter the feed hole 41. Specifically, the feed hole 41 is located on the applicator rod 4 as close as possible to the lower part of the inner plug 6, that is, at a higher position inside the bottle body 1. When the bottle body 1 is upright, the cosmetic will not remain in the feed channel 42 and the feed hole 41. The feed hole 41 is located at the bottom end of the feed channel 42 and is also radially through the applicator rod 4, so that the applicator rod 4 has two connections to the feed channel 42 for the cosmetic to enter.

[0068] The packaging container also includes a bottle cap 2, which is detachably connected to the mounting base 3 and can cover the outside of the applicator head 5. In some embodiments, when the bottle cap 2 covers the outside of the applicator head 5, it can also block the discharge hole 51 on the applicator head 5 to prevent cosmetics from leaking out. When using the applicator component at the bottom of the applicator rod 4 to apply cosmetics, the bottle cap 2 can be removed from the bottle body 1 together with the applicator.

[0069] In this packaging container, the bottle body 1 is preferably made of a soft bottle, such as silicone or soft plastic. This allows the bottle body 1 to be pressed during use to change the volume of its inner cavity, thereby squeezing out the cosmetics inside the bottle body 1 for easy access.

[0070] The specific structure of the spreadable packaging container and spreader is described below with reference to various embodiments. It should be noted that these descriptions are for the purpose of helping to understand the present invention, but do not constitute a limitation on the present invention.

[0073] In this embodiment, see Figures 2 to 4 As shown, the applicator 4 includes a rod portion 43 and a plug portion 44 connected along the axial direction. The plug portion 44 is located on the upper part of the rod portion 43. The plug portion 44 can be inserted into the discharge channel 52, so that the feed channel 42 and the discharge hole 51 are connected through the discharge channel 52 to realize the output of cosmetics.

[0074] In specific configuration, the applicator 4 is also provided with multiple annular columns to facilitate connection with the mounting base 3 and for axial limiting, so that the applicator 4 can be inserted into the mounting base 3 and fixed to the mounting base 3.

[0075] Example 2

[0076] See Figures 5 to 8 As shown, the main difference between this embodiment and embodiment 1 is that in this embodiment, the rod part 43 and the plug part 44 of the applicator 4 are set separately and then cooperate with each other along the axial direction before being connected to the applicator head 5.

[0077] Specifically, in this embodiment, the applicator head 5 is provided with an axially extending discharge channel 52, and the discharge hole 51 is provided at the top of the discharge channel 52; the applicator also includes a connector 7, which has an axially penetrating hollow cavity. The connector 7 is axially fitted on the upper part of the applicator rod 4, and the upper part of the connector 7 is fitted into the discharge channel 52. The feed channel 42 and the discharge channel 52 are interconnected through the hollow cavity.

[0078] See Figures 6 to 8 As shown, the connector 7 includes a columnar portion 71 and a mounting portion 72 located below the columnar portion 71. A hollow cavity is provided on the columnar portion 71, and the columnar portion 71 is inserted into the discharge channel 52. The mounting portion 72 has a mounting cavity, and the upper part of the applicator 4 is inserted into the mounting cavity, so that the hollow cavity is axially connected to the feed channel 42.

[0079] In this embodiment, the applicator head 5 is a hollow cylinder, with its inner cavity forming a discharge channel 52 and a discharge hole 51 located at its top. When specifically configured as a finished product, this... Figures 6 to 8 The outer side of the application head 5 shown is covered with another layer of flexible application components such as a sponge or brush to improve the application feel or achieve the desired application effect.

[0080] Example 3

[0081] See Figures 9 to 12 As shown, the main difference between this embodiment and embodiment 2 is the shape of the application head 5. The application head 5 in this embodiment is flatter and larger, which can achieve application over a larger area.

[0082] Example 4

[0083] See Figures 13 to 17 As shown, the main difference between this embodiment and Embodiment 1 lies in the arrangement of the applicator head 5 and the applicator rod 4.

[0084] In this embodiment, the applicator head 5 adopts a side-discharge method, that is, the discharge hole 51 is located on the side of the applicator head 5. Specifically, the applicator head 5 has a joint portion 53 that cooperates with the applicator rod 4, and an applicator body 54 extending upward from the joint portion 53. The discharge hole 51 is located between the outer peripheral wall of the applicator body 54 and the joint portion 53. The upper part of the applicator rod 4 is provided with a joint seat 45, which has a discharge cavity 45b. When the joint portion 53 and the joint seat 45 are axially engaged, the feed channel 42 communicates with the discharge hole 51 through the discharge cavity 45b.

[0085] Here, the applicator body 54 has two applicator surfaces 54a arranged opposite to each other. The two applicator surfaces 54a extend obliquely and intersect at the top of the applicator head 5. The discharge hole 51 is located between the applicator surface 54a and the joint 53. The cosmetic in the feed channel 42 enters the discharge chamber 45b and then reaches the applicator head 5. Subsequently, it flows from the discharge hole 51 to the applicator surface 54a, so that it can be easily applied and used.

[0086] In this embodiment, the joint 53 is provided with a joint cavity, and the discharge hole 51 is interconnected with the joint cavity; the joint seat 45 is fitted into the joint cavity, wherein at least one baffle 45a is provided in the inner cavity of the joint seat 45 to divide the inner cavity of the joint seat 45 into multiple non-communicating sub-chambers, one of which is connected to the feed channel 42 and constitutes the discharge chamber. In this way, while maintaining the axial connection and fit between the joint seat 45 and the joint 53, the volume of the discharge chamber 45b can be minimized, thereby reducing the amount of cosmetic residue in the discharge chamber 45b.

[0087] Example 5

[0088] See Figures 18 to 22As shown, in this embodiment, the applicator head 5 is densely covered with discharge holes, and the mounting base 3 is provided with a connecting port 32. The lower part of the applicator head 5 abuts against the connecting port 32, so that the connecting port 32 and the discharge holes are interconnected. Specifically, the top of the mounting base 3 is provided with a plug post 31, and the plug post 31 is provided with a through hole extending along the axial direction, the upper part of which forms the connecting port 32; the applicator head 5 can be a sponge-shaped applicator head, which is fixedly inserted into the plug post 31, thereby being fixedly installed on the mounting base 3 and making the discharge hole and the connecting port 32 interconnected.

[0089] The applicator also includes a one-way valve assembly 8 located on the top of the applicator 4. The one-way valve assembly 8 is arranged in a one-way communication from the feed channel 42 toward the connection port 32. When the one-way valve assembly 8 is open, the cosmetic in the bottle 1 can reach the connection port 32 from the feed channel 42 via the one-way valve assembly 8, and then flow out from the discharge hole on the applicator head 5 for use.

[0090] Specifically, see Figures 19 to 22 As shown, the one-way valve assembly 8 includes a valve seat 81 and a valve core 82 that cooperate with each other. The valve seat 81 has an axially communicating valve hole. The valve seat 81 is fixedly installed on the top of the applicator 4, and its valve hole is axially communicating with the feed channel 42. The valve hole has a plurality of ribs 81b that extend radially inward. All the ribs 81b are distributed circumferentially and spaced apart from each other, forming an axially penetrating liquid flow channel between two adjacent ribs 81b. All the ribs 81b surround a hole 81a. The valve core 82 includes a valve post 82a and a valve plate 82b located on the valve post 82a. The valve post 82a can be inserted into the hole 81a, and the valve plate 82b can cover the valve hole. When the valve plate 82b deforms upward relative to the valve post 82a, the valve hole communicates with the communication port 32.

[0091] In specific settings, the valve core 82 is preferably made of silicone or rubber, and its valve stem 82a is inserted into the socket 81a to keep the valve core 82 fixedly installed on the valve seat 81; the valve plate 82b is thin and can deform relative to the valve stem 82a when subjected to pressure, thereby opening the liquid flow channel formed between the various ribs 81b, so that the cosmetic can flow through the liquid flow channel to the top of the valve core 82 and reach the application head 5 through the connecting port 32.
