This invention generally relates to the technical field of containers for fluid materials, and more particularly, to an eye cream packaging material capable of preventing the introduction of air when taking a fluid material out from a container.
Fluid materials are normally stored in containers. For example, cosmetic materials are normally stored in bottles. Some of the fluid materials have an inclination to deteriorate when they come in contact with air. Therefore, to ensure its quality, a fluid material must be kept in containers in a closed state and isolated from air during the compounding process.
An eye cream is a skin care cosmetic used for the skin around eyes. Except for moisturizing and shielding functions, it may also possess functions such as tightening the skin around eyes, relieving under-eye dark circles, as well as alleviating wrinkles and fine lines after the addition of various functional components and active substances.
An eye cream bottle is a container for storing an eye cream. During the compounding process, for conventional eye cream bottles, the introduction of air or impurities is inevitable, resulting in poor quality and shortened service life of the eye cream in the container. Yet worse, when the interior of the container circulates with the outside air, the odor and the active substances of the eye cream are changed.
The purpose of the present invention is to provide an eye cream packaging container, capable of preventing outside air and foreign objects from entering a container, thereby guaranteeing the quality of a fluid material in the container.
To achieve the above purpose, the present invention adopts the following technical solution: an eye cream packaging container, comprising an outer bottle, wherein a material accommodating assembly for accommodating a fluid material to be dispensed is arranged in the outer bottle, and a bottleneck of the outer bottle is connected with a material dispensing assembly for allowing the fluid material in the material accommodating assembly to be pressed out;

The eye cream packaging container of the present invention, comprising an outer bottle (1), wherein a material accommodating assembly 2 for accommodating a fluid material 5 to be dispensed is arranged in the outer bottle 1, a bottleneck 11 of the outer bottle 1 is connected with a material dispensing assembly 3 for allowing the fluid material 5 in the material accommodating assembly 2 to be pressed out, wherein air is prevented from being introduced during the whole process.
The material accommodating assembly 2 comprises an inner container 21 and a flexible material bag 22 arranged in the inner container 21. The flexible material bag 22 is independent from the inner container 21 and is obtained by means of injection molding of silica gel. The wall thickness of the flexible material bag 22 is consistent. The upper end edge of the inner container 21 is connected to the top of the bottleneck 11 of the outer bottle 1, and the upper end edge of the flexible material bag 22 is sleeved outside the outer edge of the upper end of the inner container 21. When the flexible material bag 22 contracts, its internal space is reduced, and a space exists between the inner container 21 and the flexible material bag 22. The upper side of the inner container 21 is provided with a plurality of through openings 211 for allowing air to flow into the space between the inner container 21 and the flexible material bag 22, thereby ensuring the contraction of the flexible material bag 22 under the negative pressure suction.
The flexible material bag 22 is flexible and deformable, and its interior is capable of storing a fluid material 5 (e.g., a fluid cosmetic). The fluid material 5 is in a volume defined by the flexible material bag 22, and the fluid material 5 does not need to occupy the entire volume defined by the flexible material bag 22, while other substances may occupy the entire volume defined by the flexible material bag 22.
The material dispensing assembly 3 comprises a middle seat 31, a middle seat inner cover 32 and a flexible manual press cap 33. The middle seat 31 is a structure provided with an upper opening and a lower opening. The middle seat inner cover 32 is arranged in the middle seat 31, the middle seat inner cover 32 is connected to the outside of the bottleneck 11 of the outer bottle 1. The middle seat 31 plays a role in protecting the middle seat inner cover 32, and the middle seat inner cover 32 is located directly above the flexible material bag 22. A negative pressure one-way valve plug 34 is arranged in the middle seat inner cover 32, and the one-way valve plug 34 is communicated with the flexible material bag 22 for sucking the fluid material 5 in the flexible material bag 22.
A flexible manual press cap 33 is arranged at the top of the middle seat inner cover 32 in an airtight manner, and the middle of the flexible manual press cap 33 is provided with a convex pressing region 331 and a convex discharging region 332 that are adjacent to each other. The pressing region 331 and the discharging region 332 have convex arc surfaces, and a discharging notch 3321 is formed in the discharging region 332. The pressing region 331 and the discharging region 332 are provided with a small cavity, and the pressing region 331 is located on the upper side of the one-way valve plug 34. The pressing region 331 and the one-way valve plug 34 are substantially in a straight line, thereby allowing the one-way valve plug 34 to suck the fluid material 5 in the flexible material bag 22 into the cavity in the pressing region 331.
When the pressing region 331 is pressed to deform, a negative pressure is formed in the pressing region 331, and when the pressing region 331 is released, the pressing region 331 is restored to an original state under its own elasticity. During this process, the one-way valve plug 34 is capable of sucking the fluid material 5 in the flexible material bag 22 up and propelling the soft material bag 22 to deform and contract to open the discharging notch 3321. At this point, when the pressing region 331 is pressed, a certain amount of the fluid material 5 in the pressing region 331 flows into the discharging region 332 and is discharged from the discharging notch 3321. When the pressing region 331 is released, the discharging notch 3321 is closed.
Further, the middle seat inner cover 32 is provided with a through hole 323, and the one-way valve plug 34 is arranged in the through hole 323. When the fluid material 5 in the flexible material bag 22 is consumed to a certain extent, the flexible material bag 22 deforms and contracts to approach the one-way valve plug 34. Under such circumstances, the one-way valve plug 34 is easily blocked, resulting in the failure of completely discharging the fluid material 5 in the flexible material bag 22. Therefore, a plurality of anti-blocking columns 321 are arranged at the bottom of the one-way valve plug 34 along the lower portion of the through hole 323, and a through opening is formed between every two adjacent anti-blocking columns 321. As long as one of the through openings operates normally, a smooth suction of the one-way valve plug 34 is ensured.
In another preferred embodiment, the bottom of the flexible manual press cap 33 is provided with a manual press cap tray 333, and the top of the middle seat inner cover 32 is provided with an annular protruding edge 322. The manual press cap tray 333 is connected to the annular protruding edge 322, and the one-way valve plug 34 is located in an area enclosed by the annular protruding edge 322. The manual press cap tray 333 is made of a hard PC material, and the manual press cap tray 333 may be connected to the annular protruding edge 322 in any suitable ways, including a threaded connection or snap-fit engagement. For the snap-fit engagement, the manual press cap tray 333 and the annular protruding edge 322 may adopt a known structure of the prior art.
Furthermore, the upper end edge of the flexible material bag 22 interacts with the upper end edge of the inner container 21 and the middle seat inner cover 32 in an airtight manner, thereby ensuring that the flexible material bag 22 is in a closed state and the inside of the flexible material bag 22 is isolated from the outside air and foreign objects.
To prevent the manual press cap 33 from being pressed mistakenly and make the container aesthetically appealing, the top of the middle seat 31 is connected to a flip cover 4, and when the flip cover 4 is in a closed state, the opening at the top of the middle seat 31 is sealed.
When the container is no longer used, the one-way valve plug 34 blocks the through hole 323 such that the flexible material bag 22 is isolated from the exterior. Moreover, the flip cover 4 enables the fluid material 5 in the flexible material bag 22 to be stored for a prolonged period. When there is a need to use the container, the flip cover 4 is opened and the pressing region 331 is pressed such that the cavity in the pressing region 331 is compressed. In this way, the fluid material 5 in the pressing region 331 enters the discharging region 332, and a certain amount of the fluid material 5 in the discharging region 332 is discharged from the discharging notch 3321. Through the aforesaid operation, the discharging amount of the fluid material 5 is conveniently controlled.
After a proper amount of the liquid material 5 is discharged, the pressing region 331 is released, and the pressing region 331 is restored to an original state under its own elasticity. At this point, the cavity in the pressing region 331 possesses a certain vacuum pressure, so that the one-way valve plug 34 is opened, and the flexible material bag 22 deforms and contracts to propel the fluid material 5 to move upwards. In this way, the fluid material 5 enters the cavity in the pressing region 331 through the one-way valve plug 34 until a pressure balance in the cavity of the pressing region 331 is achieved.
Further, both the inner container 21 and the flexible material bag 22 are configured to be a hollow cylindrical shape, and both the top of the inner container 21 and the top of the flexible material bag 22 are open. The plurality of through openings 211 formed in the inner container 21 allow the interior of the inner container 21 to communicate with the outside air. The flexible material bag 22 is made of a silica gel material, which facilitates the deformation and contraction of the flexible material bag, thereby allowing the fluid material 5 to be discharged without the introduction of air. When the fluid material 5 in the flexible material bag 22 is completely discharged, the flexible material bag 22 retracts, and the space inside the flexible material bag 22 for containing the fluid material 5 disappears.
It should be understood that the device of the present invention is not limited to the specific forms disclosed. Contrarily, all variants, equivalents and alternatives of the device of the present invention shall fall into the scope defined by the claims. For example, although the device of the present invention is particularly suitable for use with a fluid cosmetic, for those skilled in the art, the device of the present invention may be used for other fluid materials 5.
In another preferred embodiment, although the inner container 21 and the flexible material bag 22 are configured to be a cylindrical shape, other shapes such as a cube, a cuboid, a prism or a circular truncated cone may also be employed. In addition, although the flexible material bag 22 is preferably an integral piece made of silica gel, other flexible deformable materials such as thermoplastic elastomer, thermoplastic rubber and styrenic thermoplastic elastomer may also be employed.
In this embodiment, the one-way valve plug 34 and the flexible manual press cap 33 are made of one of materials selected from silica gel, thermoplastic elastomer, thermoplastic rubber and styrenic thermoplastic elastomer, and the one-way valve plug 34 is arranged in a direction from the flexible material bag 22 to the cavity in the pressing region 331. In different embodiments, the material of the outer bottle 1 and the flip cover 4 may be translucent, transparent, semi-transparent or opaque.
Furthermore, the fluid material 5 may be one selected from an eye cream, a drug, an aqueous solvent and an emulsion, or the fluid material 5 may be any other fluid cosmetics.
