Description

A MULTIPURPOSE CASE

Technical Field

The present invention relates to a multipurpose case, more particularly to a multipurpose case used as a housing of a cosmetic tool, such as a brush set including a lip brush and a blusher brush, or used as a housing of a ball-point pen, a color pencil, a blade, a gimlet, and a pastel crayon, capable of allowing slidable withdrawal of the above elements at once while having a simple construction.

Background Art

In general, various kinds of brushes are widely available for cosmetic use. The brushes are comprised of a bar and a brush member or eyeliner formed at one end of the bar. The brushes are stored in a brush bag without a case .

For example, as shown in FIG. 1, the brush includes a bar SC made of metal and a brush member Br such as a blusher brush or eyeliner fixedly formed at one end of the bar SC. A plurality of brushes are stored in a brush bag (not shown) . A user selectively uses the brush for making-up the face of the user and stores the brush again in the brush bag after completing the making-up .

However, the brush member fixed at one end of the bar is exposed to an exterior, so it is inconvenient for the user to carry the brush. In addition, cosmetic powder sticking to the brush member may contaminate an interior part of the brush bag. Furthermore, the brush member is easily damaged when it makes contact with other objects, so the life span of the brush member is shortened. FIG. 2 shows a lip liner, which is a kind of conventional cosmetic tool. As shown in FIG. 2, the lip liner includes an upper case 1 formed at an inner portion thereof with a plurality of linear guide slots 2, a core fixing section 103 formed at one end thereof with a guide protrusion 6 for allowing the core fixing section 103 to move along the linear guide slots 2 and formed at the other end thereof with a engagement protrusion 7 having a spiral protuberance 9, and a lower case 3 formed at an inner portion thereof with a spiral groove 4.

In the figure, the lip liner core 8 (lip liner pencil) is vertically inserted into an upper portion of the guide protrusion 6 and the engagement protrusion 7 formed at a lower end of the guide protrusion 6 is inserted into the lower case 3 so that the spiral groove 4 is meshed with the spiral protuberance 9. In addition, the guide protrusion 6 is engaged with the linear guide slot 2 formed in the upper case so that the guide protrusion 6 may be moved up and down linearly.

When using the lip liner, a user firstly rotates the body 100 of the lip liner while manually gripping the upper case 1. At this time, the engagement protrusion 7 having the spiral protuberance 9 moves up along the spiral groove 4 so that the core fixing section 103 moves up.

If the core fixing section 103 moves up, the lip liner core 8 fixed to the guide protrusion 6 of the core fixing section 103 is linearly moved up due to the guide protrusion 6 engaged with the linear guide slot 2.

The downward movement of the lip liner core 8 is the reverse of the upward movement of the lip liner, so it will not be further described below.

As mentioned above, the conventional lip liner structure includes a short spiral protrusion formed at an outer portion of the core fixing section 103 and a long spiral slot formed at an inner portion of the lower case 3. Such a lip liner structure is not only used for lip liners, but also used for other cosmetic tools or stationery materials.

However, it is very difficult to form the spiral slots in the inner portion of the lower case, so the productivity of the lip liner is lowered. In addition, it takes a long time to assemble the lip liner.

Best Mode for Carrying Out the Invention

Reference will now be made in detail to the preferred embodiments of the present invention.

FIGS. 3 to 5B are views showing a multipurpose case according to one embodiment of the present invention and an assembling process thereof. FIGS. 6 to 8B are views showing various embodiments of a multipurpose case according to other embodiments of the present invention. A multipurpose case 10 of the present invention is divided into upper and lower parts as shown in the drawings .

Referring to FIG. 3, the multipurpose case 10 of the present invention mainly includes a case 100 and a core fixing section 200 formed at an upper end thereof with a core 228 (pencil) and slidably moved up and down within the case 100.

A first supporting section 110 is formed at a lower portion of the case 100 and a stepped portion 111 is formed at a lower portion of the first supporting section 110. A first tube 101 having a predetermined length is coupled to an outer surface of the first supporting section 110. The first tube 101 is fixed to the stepped portion 111.

A pair of connection members 120 are vertically installed on an upper portion of the first supporting section 110 and engagement protrusions 121 are integrally formed at an inner portions of the connection members 120 in order to fix a guide member 210.

A second supporting section 130 is formed at upper ends of the connection members 120. An outer diameter of the second supporting section 130 is smaller than a distance between the connection members 120, which are vertically extend from the upper portion of the first supporting section 110. A second tube 102 is arranged around the second supporting section 130.

The second supporting section 130 is divided into two parts corresponding to the connection members 120, and a perforation hole 131 is formed at a center of the second supporting section 130. Due to the perforation hole 130 formed at the center of the second supporting section 130, a vertical member 220 of the core fixing section 200 is easily assembled into the case 100 and easily moved up and down.

The guide member 210 is formed at a lower portion of the core fixing section 200. The guide member 210 is installed at an upper portion of the first supporting section 110. Guide slots 211 are formed at both sides of the guide member 210. The connection members 120 are accommodated in the guide slots 211 so that the core fixing section 200 can be vertically moved up and down.

Engagement slots 212 to be engaged with the engagement protrusions 121 of the connection members 120 are provided in the guide slots 211 formed at both sides of the guide member 210 so as to prevent the core 226 from being downwardly moved.

An outer diameter of the guide member 210 is smaller than the distance between the connection members 120, which are vertically installed on the upper portion of the first supporting section 110, so a third tube 201, into which the guide member 210 is inserted, can be moved upwards without being interrupted with the connection members 120.

The vertical member 220 is vertically formed at a center of the guide member 210 and a supporting member 230 is provided at an upper end of the vertical member 220. A core supporting member 225 is coupled to the supporting section 230 so as to prevent the core 226 from being moved.

In addition, a lid is can be coupled to an outer peripheral portion of the third tube 201 as required by a user. Although the multipurpose case 10 shown in FIG. 3 has a cylindrical shape, it can be modified into another shapes. According to other embodiments of the present invention, the multipurpose case 10 may have a triangular sectional shape, a polygonal sectional shape or an oval sectional shape.

Hereinafter, an assembling process and an operation of the multipurpose case 100 will be described with reference to FIGS. 4A to 5B.

Referring to FIG. 4A, the vertical member 220 of the core fixing section 200 is positioned in the perforation hole 131 by widening a space between two parts of the second supporting section 130, which is integrally formed with the connection members 120 vertically installed on the upper portion of the first supporting section 110.

At this time, the connection members 120 are arranged in match with the guide slots 211 of the guide member 210 in such a manner that the guide member 210 moves up and down along the connection members 120. Then, the first tube 101 is coupled to an upper portion of the first supporting section 110.

In addition, as shown in FIG. 4B, the second tube 102 is coupled to an upper end of the second supporting section 130 so as to prevent two parts of the second supporting section from being separated from each other.

Then, as shown in FIG. 4C, the third tube 201 is assembled around the guide member 210 such that the third tube 201 surrounds the first and second tubes 101 and 102, which are coupled to the first and second supporting sections 110 and 130, thereby completing the assembling process.

Hereinafter, the operation of the multipurpose case 10 will be described in detail with reference to FIG. 5A and 5B.

Firstly, in order to withdraw the core 226 accommodated in the core fixing section 200, a user grips the first tube 101 of the case 100 shown in FIG. 5 using one hand, and rotates the third tube 201 by gripping an upper portion of the third tube 201 using the other hand. Thus, as shown in FIG. 5B, the core fixing section 200 coupled to a lower end of the third tube 201 is protruded into an upper portion of the second tube 102 so that the user can use the core 226 provided at the upper end of the core fixing section 200.

At this time, since the guide slots 211 formed at both sides of the guide member 210 are engaged with the connection members 120, the guide member 210 can be vertically guided between the connection members 120. In addition, while the guide member 210 is vertically guided, the engagement slots 212 formed in the guide slots 211 can be engaged with the engagement protrusions 121 of the connection members 120, thereby preventing movement of the guide member 120 during use of the core 226.

On the other hand, the multipurpose case can be used as a case of cosmetic tools and stationery materials, if the user exchanges the core 226 of the core supporting member 225 with a color pencil, a pastel crayon, solid paste, a lip brush, an eye brush and a blusher brush.

FIG. 6 shows a multipurpose case 10 according to another embodiment of the present invention used as a case of a ball-point pen, in which the core 226 fixed in the core fixing section 200 is a pencil of the ballpoint pen. The structure of the multipurpose case 10 shown in FIG. 6 is identical to the structure of the multipurpose case 10 shown in FIG. 3 except for a pencil supporting hole 226a formed at a center of the core fixing section so as to support the core (pencil) 226.

The pencil supporting hole 226 can be easily fabricated through a die-casting process by modifying a shape of a mold.

That is, the multipurpose case according to the present invention can be used as a case of stationery materials, such as a ball-point pen, a blade, and a gimlet, and as a case of cosmetic tools, such as a brush set.

FIGS. 7A to 8B are views showing various embodiments of the present invention, where various kinds of cores 226 are provided in the multipurpose case depending on the various shapes of the core supporting member 225. Referring to FIGS. 7A to 8B, cores 226 are stored in the multipurpose case when they are not used and withdrawn from the multipurpose case for use. Since the core 226 is hidden in the multipurpose case or protruded from the multipurpose depending on an operation of the core fixing section 200, which is slidably moved up and down within the case 100, the multipurpose case can be safely stored in a bag without contaminating the bag. In addition, the core is prevented from making contact with another objects when it is stored in the bag, so the life span of the core can be extended. The multipurpose case of the present invention can be used for a case of a brush, a blade and a gimlet, while improving the reliability thereof.

FIG. 9 is an exploded perspective view showing a multipurpose case according to another embodiment of the present invention, FIG. 10 is a side sectional view of the multipurpose case shown in FIG. 9 when the multipurpose case is in a state of being assembled, and FIG. 11 is a side sectional view of the multipurpose case when a core is withdrawn from the multipurpose case .

According to the present embodiment, the multipurpose case includes a core 600 having various sectional shapes including triangular, rectangular, polygonal, and oval shapes, an upper body 718 and a lower body 722. In addition, the multipurpose case includes a core fixing section 700 formed at an upper portion thereof with the core 600 and moving the core 600 up and down so as to withdraw the core 600 out of the multipurpose case, a fixing member 800 accommodating the core fixing section 700 therein and guiding the core fixing section 700 when the core fixing section 700 moves up and down, a middle case 500, which is arranged around the fixing member 800 and to which the core fixing section 700 is fixed such that the core fixing section 700 is moved up by using one hand of a user, a lower case 900 accommodating the middle case 500 therein, and an upper lid 400.

Hereinafter, a case used for a cosmetic tool will be described in detail.

When sectional shapes or external appearances of the upper lid 400 and the lower case 900 are formed in a predetermined shape, such as triangular, rectangular, polygonal, and oval shapes, it is preferred to form the core 600 in a predetermined shape corresponding to the shapes of the upper lid 400 and the lower case 900. In the present embodiment shown in FIGS. 9 to 11, the multipurpose case has a cylindrical shape.

The core fixing section 700 includes the upper body 718 formed with a plurality of fixing holes 716 and the lower body 722 vertically extending from a lower portion of the upper body 718 and formed at both lower sides thereof with wings 720.

The middle case 500 has a cylindrical shape and is formed at an upper peripheral portion thereof with a plurality of slits 514. The slits 514 are provided to prevent the middle case 500 from being slid from user's hand when the user pushes the middle case 500.

The fixing member 800 is formed at both sides thereof with guide slots 824, into which the wings 720 of the core fixing section 700 are inserted in order to slidably moved up and down along the guide slots 824.

A plurality of engagement protrusions 832 are formed at one side of the guide slots 824. Preferably, 3 to 5 engagement protrusions 832 are provided in the guide slots 824. In this case, the wings 720 sequentially make contact with the engagement protrusions 832 while the core fixing section 700 is being moved up and down so that the movement of the core fixing section 700 is periodically stopped. In addition, as compared with the conventional spiral protrusion or spiral slots, the guide slots 824 can be easily fabricated.

An upper fixing cap 510 is fixedly inserted into the upper lid 400. A touch part 512 is formed at a lower portion of the upper fixing cap 510. The touch part 512 is protruded radially inwards so that a vacuum is formed in the fixing member 800 when the touch part 512 makes contact with an outer peripheral portion of the fixing member 800. It is preferred to prevent air or moisture from penetrating into the fixing member 800 by allowing the touch part 512 to make contact with the upper end of the fixing member 800. By forming the vacuum state in the case, the core is prevented from being solidified with properly maintaining wet in the core.

The touch part 512 has a semi-circular sectional shape and is preferably protruded radially inwards. However, it is possible to form the touch part 412 in various shapes, such as a polygonal shape or an oval shape, adapted for the case.

Preferably, the touch part 512 is made of rubber or silicon.

A filling hole 830 is formed at a center of a lower fixing cap 828 and a stepped portion 826 is formed at a lower portion of the lower fixing cap 828. The fixing member 800 is vertically installed on the stepped portion 826.

According to the multipurpose case having the above structure, the guide slots 824 of the fixing member 800 can be formed in a long size. Thus, manufacturing and assembling processes of the multipurpose case are very convenient. In addition, the user can withdraw the core using one hand, so it is very convenient for the user to use the multipurpose case.

The conventional case for cosmetic tools and stationery materials is required to have formed a long spiral slot at an inner portion of the case so as to withdraw the core in a long size. For this reason, the case is required to have a relatively long size so as to form the long spiral slot therein. However, it is very difficult to form a long spiral slot in the inner portion of the case. On the contrary, the multipurpose case of the present invention can be slidably moved along the guide slots formed in the fixing member in a simple manner, so that the productivity of the multipurpose case can be improved.

In addition, it is well known to those skilled in the art that upper and lower parts of the multipurpose case of the present invention can be symmetrically formed.

The core fixed to the core fixing section 700 is soft solid material and is exchanged with various kinds of cores, such as a pastel crayon, a solid paste, a perfume pen, a fountain pen, a brush pen, an eye liner, a mascara, and a lip stick.

This is possible by forming the guide slots at both sides of the fixing member 800 in a long size.

Industrial Applicability

As can be seen from the foregoing, the multipurpose case according to the present invention has a simple structure so an assembling process thereof is simplified, so the productivity thereof is improved without a faulty assembly occurring. In addition, manufacturing cost of the multipurpose case can be reduced.

In addition, it is convenient for a user to withdraw the core from the multipurpose case.

Furthermore, the core is hidden in the multipurpose case when it is not used, so a bag storing the multipurpose case is prevented from being contaminated and the core is prevented from making contact with other objects so the life span of the core is expanded.

In addition, the multipurpose case can be widely used as a case of cosmetic tools and stationery materials . While this invention has been described in connection with what is presently considered to be the most practical and preferred embodiments, it is to be understood that the invention is not limited to the disclosed embodiments and the drawings, but, on the contrary, it is intended to cover various modifications and variations within the spirit and scope of the appended claims .
