Description

POWDER CONTAINER INCLUDING BUILT-IN PUFF
The present disclosure relates to a powder container for the application of cosmetic powder using a puff received in a lid. More particularly, the present disclosure relates to a powder container including a built-in puff, wherein a lid and a sifting part are connected to each other in a simple manner using an opening and closing pivot configuration provided as a hinge assembly formed of a synthetic resin by injection molding rather than a metal pin assembly, thereby providing a product conforming to the trend of being environmentally friendly, and high sealing capability of cosmetic powder contained in a container body may be maintained by closing the container body with a container cap.
In a variety of related-art compact-type cosmetic containers each including a powder container in which cosmetics is contained, there is a hinge structure for facilitating opening and closing of an inner container and an inner cap, in addition to a cap configured to move to open and close a container body. Most of such hinge structures use a metal pin assembly. The hinge pin assembly structure is significantly complicated. Due to the use of metal pins, separate collection is difficult and annoying, thereby significantly reducing the rate of reuse or recycle of resources. In terms of environmentally friendliness, there have been a number of undesirable consequences, such as environmental pollution.
In addition, a variety of structures for providing tightness or sealing to various forms of cosmetics including cosmetic powder has been proposed for related-art cosmetic containers. However, a significantly complicate sealing structure is used. In addition, although structures using a number of components are used, it has been difficult to provide or maintain a desirable level of tightness. Accordingly, an improvement in the structure is required.

Hereinafter, exemplary embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings.
FIGS. 1 to 11 are views illustrating the structure of a powder container 100 including a built-in puff according to a first embodiment of the present disclosure.
Referring to FIGS. 1 to 11, the powder container 100 including a built-in puff according to the first embodiment of the present disclosure includes a container body 10, a sifting part 20, a lid 30, a hinge assembly 40, and a cap 50. A puff 60 may be built in the lid.
The container body 10 may have a storage space 12 configured to be open in one direction such that various forms of cosmetic powder P is contained therein. A first catching protrusion 14a is formed on an upper portion of the storage space, i.e., an upper outer portion of an open area 14. A threaded portion 16 is formed on the stepped outer circumferential surface formed below the first catching protrusion 14a.
The inner circumferential surface of the lower portion of the container body 10 is gradually curved to be concave toward the central portion, thereby facilitating the entire amount of cosmetic powder to be taken out through a mesh of the sifting part 20 described later.
The sifting part 20 is detachably coupled to the open area 14 of the container body 10 through a coupling recess 22 of the coupling portion 21 formed around the upper outer circumferential portion. Here, a support portion 23 extends downward and inward from the coupling portion 21 so as to be concave. The support portion 23 is configured to be fitted into the storage space 12 of the container body 10.
A second catching protrusion 22a may be further formed on the inner circumferential portion of the coupling recess 22. When the coupling recess 22 is coupled to the open area 14 of the container body, the second catching protrusion 22a is engaged with the first catching protrusion 14a formed on the upper outer portion of the open area 14.
Thus, when the sifting part 20 is coupled to the container body 10, coupling force may be firmly maintained due to coupling between the catching protrusion 14a formed on the open area 14 and the second catching protrusion 22a formed on the coupling recess 22.
Each of the catching protrusion 14a and the second catching protrusion 22a provided in the open area 14 and the coupling recess 22, respectively, to maintain the coupling force of the sifting part 20 with respect to the container body 10 has been described as being in the form of a catching protrusion, but is not limited to this term. Each of the catching protrusion 14a and the second catching protrusion 22a may be embodied in a variety of structures capable to perform the same or equivalent function.
A peripheral portion of a mesh 24 formed of a flexible material is fixed to the lower portion of a bottom surface 23a of the support portion 23 by a mesh fixing ring 24a. A portion of the mesh may be exposed externally through an exposure space 23b formed in the bottom surface of the support portion.
A portion of the mesh 24 is exposed externally through the exposure space 23b formed in the bottom surface 23a of the support portion 23. It is possible to perform the application of makeup by applying the puff 60 with the cosmetic powder P through the exposed portion.
Since the mesh 24 is formed of a flexible material, the mesh 24 may be pressed to the bottom of the storage space 12 of the container body 10 according to the consumed amount of the cosmetic powder P contained in the storage space 12 of the container body 10, so that the entire amount of the cosmetic powder may be taken out and used.
In addition, a sealing rim 23c may further protrude from the outer circumferential portion of the sidewall of the support portion 23 of the sifting part 20. When the sifting part 20 is inserted into the storage space 12 of the container body 10, a portion of the sealing rim 23c nay be in close contact with the inner circumferential portion of the storage space, thereby providing a reliable seal.
Due to the sealing rim 23c protruding from the sidewall of the support portion 23, the cosmetic powder contained in the storage space 12 of the container body 10 can be prevented from leaking through the open area 14 of the container body 10 and the intrusion of the air to the cosmetic powder can be blocked.
In addition, due to the configuration of the sealing rim 23c, when the support portion 23 is fitted into the storage space 12 of the container body 10, the support portion 23 can be prevented from moving in the lateral direction. Consequently, reliable coupling of the sifting part 20 can be promoted.
Furthermore, an inclined entry guide surface 23d is further formed on the lower portion of the outer circumferential surface of the sidewall of the support portion 23 of the sifting part 20. When the support portion 23 is fitted into the storage space 12 through the open area 14 of the container body 10, the inclined entry guide surface 23d may guide the support portion 23 to be more smoothly fitted into the storage space 12 without interfering with the open area.
In the meantime, a fitting recess 25 is formed to a predetermined depth on one side of the sifting part 20. The fitting recess 25 is provided for coupling of the hinge assembly 40 described later.
In addition, a lid opening angle control protrusion 26 may be further formed on the top surface of the coupling portion 21 of the sifting part 20 on which the fitting recess 25 is formed. The lid opening angle control protrusion 26 serves to properly control the degree of pivoting opening of the lid 30 described later.
Due to the configuration of the lid opening angle control protrusion 26 as described above, the lid 30 operated to be opened in one direction with respect to the sifting part 20 may be maintained in the state of an appropriate angle of opening, as illustrated in FIG. 10.
The lid 30 is coupled to the upper portion of the sifting part 20. The lid 30 may include a flange 31 formed around the upper circumferential portion and a puff base 32 extending inward and downward from the flange so as to be concave such that the puff 60 is received in and seated on the puff base 32.
Since the puff base 32 is received into the support portion 23 when the lid is coupled to the sifting part 20, the puff base 32 may have the same or similar shape as the inner circumferential portion of the support portion 23 of the sifting part.
A hinge block 33 may be formed on one side of the flange 31 of the lid 30, and hinge pins 34 may be formed on both sides of the hinge block.
In addition, a sealing pad 35 may be provided on the bottom of the lower portion of the puff base 32 of the lid 30. The sealing pad 35 is configured to seal the exposure space 23b defined by the bottom surface 23a of the sifting part 20. The sealing pad 35 may be formed by double injection.
Here, the sealing pad 35 may be formed of a nitrile-butadiene rubber (NBR) material to provide sealing capability. This material is similar to a polypropylene (PP) group, and is not required to be separated in the case of discarding.
When the lid 30 closes the sifting part 20, the sealing pad 35 is in strong contact with the top surface around the exposure space 23b defined by the bottom surface 23a of the sifting part 20, thereby closing the exposure space 23b. Consequently, the sealing of the cosmetic powder P contained in the storage space 12 of the container body 10 can be maintained.
In addition, the lid 30 may be pivoted in predetermined directions to be opened and closed through a connection to the hinge assembly 40 formed between the lid 30 and the sifting part 20 by injection molding of a synthetic resin.
Referring to FIGS. 6 and 7, the hinge assembly 40 includes first and second connecting support portions 42a and 42b connected and supported to be foldable about a central folding portion 41. Fitting blades 43 having a split structure are separately formed on the first and second connecting support portions 42a and 42b, respectively, so as to be fitted into the fitting recess 25 of the sifting part 20. In addition, hinge holes 44 are formed in the first and second connecting support portions 42a and 42b such that the hinge pins 34 are fitted into the hinge holes 44, respectively, so as to be pivotable.
In addition, the first and second connecting support portions 42a and 42b may also have a fixing protrusion 45 and a fixing recess 46 formed in a corresponding manner. When the fitting blades 43 fitted into the fitting recess 25 are folded so that the hinge holes 44 are fitted around the hinge pins 34, respectively, the first and second connecting support portions 42a and 42b serve to maintain the folded state.
In the hinge assembly 40 having the above-described configuration, as illustrated in FIGS. 8a and 8b, the first and second connecting support portions 42a and 42b separated from each other about the folding portion 41 at the center may be folded inward so as to be fitted around the hinge pins 34 of the lid 30.
In the meantime, the hinge pins 34 of the lid 30 fitted into the hinge holes 44 of the hinge assembly 40 are configured to be fittable and movable in the top-bottom direction, as seen from FIGS. 11a and 11b, so that the lid 30 is movable toward the support portion 23 of the sifting part 20.
Since the hinge pins 34 of the lid 30 are fitted into the hinge holes 44 of the hinge assembly 40 so as to be movable in the top-bottom direction as described above, when the lid 30 is pressed by the container cap 50 described later, the sealing pad 35 provided on the bottom can provide relatively strong contact force to the bottom surface 23a of the sifting part 20 having the exposure space 23b. Consequently, it is possible to provide strong sealing force to the exposure space 23b.
As seen from FIGS. 9a and 9b, on the inner circumferential surface of the fitting recess 25 and the fitting blades 43 of the hinge assembly 40 fitted into the fitting recess 25, catching means 25a and 43a for imposing the catching between the fitting recess 25 the fitting blades 43 may be further provided.
The catching means 25a and 43a are illustrated in the form of a catching protrusion and a recess in the figures, but are not limited thereto. Rather, the catching means may be embodied in a variety of shapes capable to perform the same or equivalent function.
The container cap 50 may be operated to open and close the open area 14 of the container body 10 in a screw engagement manner.
In this regard, a threaded portion 51 is formed on the inner circumferential surface of the open end of the container cap 50 so as to correspond to the threaded portion 16 formed on the open area 14 of the container body 10.
In addition, a pressing protrusion 52 further protrudes from the bottom end of the inner circumferential surface of the container cap 50. The pressing protrusion 52 is configured to press the top surface of the flange 31 of the lid 30 when the container cap is operated to close the container body in the screw engagement manner.
In the pressing protrusion 52 provided on the container cap 50, when the container cap is operated to rotate with respect to the container body, the bottom surface of the container cap is in partial contact, instead of being in entire contact, with the top surface of the flange 31 of the lid 30. Consequently, it is possible to advantageously allow the container cap 50 to be rotated by minimizing contact interference between the container cap 50 and the flange 31 of the lid 30.
In the powder container 100 including a built-in puff according to the first embodiment of the present disclosure, the lid is fitted to the sifting part 20 coupled to the container body 10 using the hinge assembly 40 formed of a synthetic resin by injection molding such that the lid may be pivoted to be opened and closed in predetermined directions. In addition, the hinge assembly 40 is hinge-coupled to the sifting part 20 and the lid 30 while the first and second connecting support portions 42a and 42b on both lateral sides are being folded about the folding portion 41 at the center. Consequently, the hinge coupling can be performed more rapidly.
In addition, due to the mutual fixing and coupling between the fixing protrusion 45 and fixing recess 46 formed on the first and second connecting support portions 42a and 42b of the hinge assembly 40 in a corresponding manner, the folding state is reliably maintained without separation from or movement with respect to the hinge pins 34. Thus, the pivot operation of opening and closing the lid 30 may be smoothly and reliably performed.
In addition, in a situation in which the hinge assembly 40 is connected and fitted to the sifting part 20 and the lid 30, due to the catching and fixing between the catching means 43a and 26a formed in a corresponding manner on the fitting blades 43 of the first and second connecting support portions 42a and 42b and the fitting recess 26 of the sifting part, any release or separation in response to the opening and closing pivot operation of the lid 30 can be prevented, so that the hinge function can be reliably performed.
In addition, when the container cap 50 is operated to close the container body 10 in a screw engagement manner, the sealing pad 35 provided on the bottom of the lower portion of the puff base 32 of the lid 30 is forced to be in close contact with the bottom surface 23a of the sifting part 20, by which the exposure space 23b is defined, in response to the lid 30 being moved downward by the container cap 50. Consequently, the exposure space 23b is sealed. Accordingly, it is possible to store the cosmetic powder P contained in the storage space 12 of the container body 10 in a sealing manner.
Furthermore, since the hinge pins 34 are fitted into the hinge holes 44 of the hinge assembly 40 so as to be movable in a top-bottom direction, the lid 30 is movable downward a predetermined distance when the container cap 50 is operated to close the container. In accordance with the rate of the downward movement, the sealing pad 35 provided on the bottom of the lower portion of the puff base 32 provides relatively strong contact force with respect to the bottom surface 32a of the sifting part.
Since the close contact force of the sealing pad 35 with respect to the exposure space 23b of the sifting part 20 may be continuously maintained unless the container cap 50 is intentionally opened from the container body 10, when the powder container 100 is being carried or stored, it is possible to prevent the cosmetic powder P contained in the storage space 12 of the container body 10 from leakage, deteriorations caused by the intrusion of the air, and the like.
In the meantime, when the container cap 50 is operated to close the container body 10, the pressing protrusion 52 formed on the inner circumferential surface of the container cap 50 rotates while in partial contact with the top surface of the flange 31 of the lid 30. Consequently, the closing operation of the container cap 50 may be performed more smoothly and properly.
In addition, in a situation in which a user intends to perform the application of makeup using the cosmetic powder P contained in the storage space 12 of the container body 10, the user opens the container body 10 by separating the container cap 50 from the container body 10. Afterwards, the user holds the puff 60 built in the lid 30 with one hand and operates the lid 30 to be open in one direction from the sifting part 20 using the hinge assembly 40. Here, the lid 30 is controlled to pivot to a suitable angle while the bottom surface of the hinge block 33 of the lid 30 is forced to be in contact with the lid opening angle control protrusion 26.
When the lid 30 is pivoted to open or close from the sifting part 20, the mesh 24 is exposed through the exposure space 23b defined by the bottom surface 23a of the support portion 22 of the sifting part. Then, the user may perform the application of makeup by applying the puff with the cosmetic powder P contained in the storage space 12 of the container body 10 by touching the exposed mesh 24 with the puff 60.
The application of makeup may be performed by applying the cosmetic powder contained in the storage space 12 of the container body 10 using the puff 60 as described above. When the application of makeup is finished, the closing operation is completed by closing the sifting part 20 with the lid 30 using the hinge assembly 40, inputting the puff 60 into the puff base 32 of the lid 30, and finally closing the container body 10 with the container cap 50. In the case of the closing operation of the container cap, the sealing pad 35 of the lid re-blocks the exposure space 23b of the sifting part 20, so that the cosmetic powder P contained in the storage space 12 of the container body 10 is provided with perfect sealing capability. Consequently, the cosmetic powder can be prevented from leakage, deteriorations, or deformation due to carrying or use.
FIGS. 12 to 17 are views illustrating a structure of a powder container 100 including a built-in puff according to a second embodiment of the present disclosure. In the description of the second embodiment of the present disclosure, the same reference numerals or symbols will be used to designate the same or like components of the first embodiment and repeated descriptions thereof will be omitted for the sake of brevity.
The powder container 100 including a built-in puff according to a second embodiment of the present disclosure is substantially the same as the first embodiment except for some configurations. That is, the sifting part 20 further includes anti-release protrusions 27, the hinge assembly 40 has a structure including catching protrusions 47 configured to catch or be caught by the anti-release protrusions, and the lid 30 further includes receptacles 36 in which the anti-release protrusions are received and supported. In addition, as another difference, the hinge assembly 40 has a separable structure. These differences will be described in more detail as follows.
The anti-release protrusions 27 may be provided on the top surface of the coupling portion 21 of the sifting part 20. The anti-release protrusions 27 provide the fitting recess 25 of the sifting part 20 with catching force for the hinge assembly 40 to which the fitting blades 43 are fitted, thereby firmly holding the hinge assembly 40 so as not to be separated or released from the fitting recess 25.
A plurality of anti-release protrusions 27 is illustrated in the figures, but is not limited thereto. The anti-release protrusions 27 may have a variety of shapes, numbers, or positions.
In addition, the receptacles 36 are provided on both sides of the hinge block 33 of the lid 30. When the lid 30 is pivotably fitted to the sifting part 20 through the hinge assembly 40, the anti-release protrusions 27 provided on the sifting part 20 are safely received and supported in the receptacles 36.
Due to the configuration of the receptacles 36 of the lid 30 as described above, the anti-release protrusions 27 of the sifting part 20 may provide a reliable engagement state with respect to the hinge assembly 40 without obstructing the opening pivoting operation of the lid 30.
In addition, as illustrated in FIGS. 14a, 14b, and 14c, the hinge assembly 40 includes the first and second connecting support portions 42a and 42b separated from each other. In the first and second connecting support portions 42a and 42b, the fitting blades 43 fitted to the fitting recess 25 of the sifting part 20 have a split structure, and the catching protrusions 47 forcibly caught by the anti-release protrusions 27 are also formed. In addition, hinge holes 44 are formed such that the hinge pins 34 of the lid 30 are fitted into the hinge holes 44, respectively, so as to be movable in a top-bottom direction and be pivotable.
Here, the fixing protrusion 45 and the fixing recess 46 formed to correspond to the first and second connecting support portions 42a and 42b of the hinge assembly 40 may further include a catching rim 45a and a catching recess 46a formed in a corresponding manner. As illustrated in FIGS. 14a and 14b, when the fixing protrusion 45 and the fixing recess 46 are fitted to each other, the catching rim 45a and the catching recess 46a may maintain strong fitting force.
According to the structure of the powder container 100 including a built-in puff according to the second embodiment of the present disclosure having the above-described configuration, when the hinge assembly 40 is assembled such that the hinge pins 34 formed on the hinge block 33 of the lid 30 are fitted into the hinge holes 44 formed in the first and second connecting support portions 42a and 42b, respectively, the first and second connecting support portions 42a and 42b are fitted to each other in a non-separated state by the coupling of the fixing protrusion 45 and the fixing recess 46. In this position, the fitting blades 43 are pushed and fitted into the fitting recess 25 of the sifting part 20. At the same time, the catching protrusions formed on the hinge assembly 40 are forced to move over the anti-release protrusions 27 formed on the sifting part 20 so as to be engaged with the anti-release protrusions 27. As the anti-release protrusions 47 are supported by and fitted to, while being received in, the receptacles 36 of the lid 30, the hinge assembly 40 can be further prevented from being detached from the fitting recess 25 of the sifting part 20.
Thus, even in the case of a decompression test, unintended impact, or the application of strong external force, the hinge assembly 40 connected and fitted to the sifting part 20 and the lid 30 can be reliably prevented from being accidently detached from the fitting recess 25 of the sifting part 20 by the engagement between the anti-release protrusions 27 and the catching protrusion 47. Consequently, it is possible to provide high assembly reliability and durability to products.
In addition, according to embodiments of the present disclosure, all of the components of the powder container 100 including a built-in puff are formed of a synthetic resin by injection molding so as to be compatible with environmentally friendly products, and are configured to be fitted to and separated from each other. In addition, no metal materials are used differently from the related art. When used products are discarded, there is no inconvenience in separate collection for recycling. Due to the convenience of separate collection, unauthorized disposal can be prevented, and resultant environmental pollution can also be prevented. In this manner, a variety of advantages can be provided.
Although the present disclosure has been described with reference to the accompanying drawings, the present disclosure is not limited thereto, and a variety of changes and alterations are possible without departing from the scope of the appended Claims.
