The present invention relates to cosmetics and, more particularly, to a container for cosmetics.
A typical container for cosmetics includes a case and a cover. The case is used to contain a lipstick or lip gloss. The cover is engaged with the case to keep the lipstick or lip gloss in the case.
The cover can be engaged with the case in various manners such as threads and magnets. Where threads are used, the case is formed with a thread for engagement with a thread formed on the cover. The cover has to be rotated relative to the case for a certain angle in a direction to engage the cover with the case adequately. The cover has to be rotated relative to the case for the angle in an opposite direction to disengage the cover from the case. Such rotation is a waste of time.
Where magnets are used, one of the magnets is connected to the case and the remaining one of the magnets is connected to the cover. The magnets attract each other to keep the cover on the case. The engagement of the cover with the case and the disengagement of the cover from the case are convenient. However, each of the magnets must be connected to the cover or the case in a correct position or the magnets would repulse each other instead of attract each other. The attachment of each of the cover or the case is troublesome for a worker.
The present invention is therefore intended to obviate or at least alleviate the problems encountered in the prior art.
It is the primary objective of the present invention to provide a magnetic container that is manufactured efficiently.
To achieve the foregoing objective, the magnetic container includes a cover assembly, a base assembly, magnets and a ferromagnetic element. The cover assembly includes an edge extending around an open end. The base assembly includes an open end inserted in the cover assembly via the open end of the cover assembly when the edge of the cover assembly covers the open end of the base assembly. The magnets are connected to the cover assembly or the base assemblies while the ferromagnetic element is connected to the base assembly or the cover assembly. The magnets are operable to magnetically attract the ferromagnetic element to keep the cover assembly covering the open end of the base assembly.
Other objectives, advantages and features of the present invention will be apparent from the following description referring to the attached drawings.
The present invention will be described via detailed illustration of the preferred embodiment referring to the drawings wherein:

Referring to
The internal cap 30 includes a closed end 31, an open end 32 that allows access to a space in the internal cap 30, and a flange 33 around the open end 32. The flange 33 includes four edges 34 and four corners 35. Adjacent two of the edges 34 meet each other at each of the corners 35. Each of the edges 34 includes a cutout 36. The internal cap 30 includes four thickened portions 37 on an external face. Each of the thickened portions 37 includes a section extending to the flange 33 and another section formed with ribs 38 extending to the closed end 31.
The profile of the ferromagnetic element 40 is similar to the profile of the flange 33. Preferably, the ferromagnetic element 40 is a plate including four edges 42 corresponding to the edges 34. Each of the edges 42 includes a hook 43 corresponding to the cutout 36 of one of the edges 34. The ferromagnetic element 40 further includes an annular portion 41. The annular portion 41 and the hooks 43 extend from a same face of the ferromagnetic element 40.
Referring to
Preferably, the depth of each of the cutouts 36 is larger than the thickness of each of the hooks 43 so that the cutouts 36 completely receive the hooks 43 to keep the hooks 43 from the walls 21 of the external cap 20. Thus, the hooks 43 do not interfere with the insertion of the flange 33 in the space 25.
The annular portion 41 of the ferromagnetic element 40 is inserted in the internal cap 30 through the open end 32, around which the flange 33 extends, when the ferromagnetic element 40 is connected to the internal cap 30. Preferably, the length of the annular portion 41 of the ferromagnetic element 40 is larger than the thickness of the flange 33.
The closed end 31 of the internal cap 30 is inserted in the space 25 of the external cap 20 via the open end 24. Each of the thickened portions 37 of the internal cap 30 abuts against an internal face of one of the walls 21 so that the internal cap 30 is fitted in the external cap 20. Thus, the combination of the flange 33 with the ferromagnetic element 40 is inserted in the space 25, adjacent to the open end 24. Now, the closed end 23 of the external cap 20 is deemed the closed end 13 of the cover assembly 11. The open end 24 of the external cap 20 is deemed the open end 14 of the cover assembly 11.
Referring to
The internal cup 60 includes a closed end 61 and an open end 62 that allows access to a space in the internal cup 60. The internal cup 60 further includes four thickened portions 64 and four corner blocks 65. Each of the corner blocks 65 is formed between two adjacent ones of the thickened portions 64 of the internal cup 60. The corner blocks 65 can be deemed thickened portions of the internal cup 60, similar to the thickened portions 64 except for in different positions. The thickened portions 64 and the corner blocks 65 are located closer to the open end 62 than to the closed end 61. Each of the thickened portions 64 includes a section extending to the open end 62 and another section formed with ribs 63 extending to the closed end 61. Each of the corner blocks 65 includes a recess 66 and ridges 67 are formed on a wall of the recess 66.
The shield 80 includes four walls 81 extending from an annular strip 82. An opening 16 is made in a center of the annular strip 82.
Referring to
The shield 80 is located on the internal cup 60 so that the former covers the thickened portions 64 and the corner blocks 65 of the latter. The thickened portions 64 of the internal cup 60 are abutted against the walls 81 of the shield 80 so that the upper section of the internal cup 60 is fitted in the shield 80. The walls 81 of the shield 80 are abutted against the walls 51 of the external cup 50 so that a lower section of the shield 80 is fitted in the external cup 50. That is, the internal cup 60 is kept in the external cup 50 by the shield 80. Now, the annular strip 82 of the shield 80 extends above the open end 54 of the external cup 50. The opening 16 of the annular strip 82 is in communication with the open end 62 of the internal cup 60. The opening 16 of the annular strip 82 is deemed the open end 15 of the base assembly 12.
The corner blocks 65 of the internal cup 60 are aligned to the bent portions 83 of the shield 80 which are in turn aligned to the bent portions 52 of the external cup 50. Thus, the external cup 50, the internal cup 60 and the shield 80 are not rotatable relative to one another.
The magnets 70 are located beneath the annular strip 82. Each of the magnets 70 inherently includes two magnetic poles 71 and 73. The magnetic pole 71 or 73 of each of the magnets 70 is in contact with the annular strip 82. It does not matter which of the magnetic poles 71 and 73 of each of the magnets 70 is in contact with the annular strip 82 for a reason to be given.
Referring to
The bent portions 22 of the external cap 20 are aligned to the bent portions 83 of the shield 80 so that the cover assembly 11 is not rotatable relative to the base assembly 12. Now, the open end 14 of the cover assembly 11 is aligned to the open end 15 of the base assembly 12 so that the space of the cover assembly 11 is in communication with the space of the base assembly 12. The combination of the space of the cover assembly 11 with the space of the base assembly 12 is used to receive cosmetics such as a lipstick.
The present invention has been described via the illustration of the preferred embodiment. Those skilled in the art can derive variations from the preferred embodiment without departing from the scope of the present invention. Therefore, the preferred embodiment shall not limit the scope of the present invention defined in the claims.
