This application claims priority to Chinese Patent Application No. 201520256016.9, filed Apr. 24, 2015, now Chinese Patent No. CN 204541166U, granted Aug. 12, 2015, which is incorporated herein by reference.
The present invention relates to a powder box.
A makeup box, such as that described in Chinese Patent No. CN203424525U granted on Feb. 12, 2014, according to the prior art typically comprises a bottom box, an inner box having an interior cavity, a box cover connected with the bottom box, an inner box cover being sealingly provided over the interior cavity of the inner box between the bottom box and the box cover, a snap frame being provided between the bottom box and the inner box, a circle of raised seal rib being provided at the periphery of the lower surface of the inner box cover, and, correspondingly, a circle of seal groove being provided at the periphery of the inner box. In a closed state of the inner box cover, the seal groove and the seal rib are fastened by each other. Under the prior art, the sealing of the inner box cover and the inner box generally is achieved by the cooperation of the seal rib and the seal groove. Therefore, during processing the box body, there is high requirement for machining precision of the seal rib and the seal groove. If deviations occur in processing of the seal rib and the seal groove, the inner box cover and the inner box may be poorly sealed or even impossible to close.
The present invention thus has an object of providing a powder box that can be effectively sealed while being efficient in manufacture and assembly.
In seeking to meet that and further objects, an embodiment of the powder box has a first box body with an interior cavity and an upward facing opening, a first box cover capable of lidding over the first box body and covering the opening, and a circle of a protruding portion or protruding portions being formed on an upper surface of the first box body and protruding upwards. As used herein, the phrase capable of lidding shall mean to be capable of forming a lid. The material of the lower surface of the first box cover is an elastomeric material capable of elastic deformation. With that, the protruding portions contact with the lower surface of the first box cover and cause elastic deformation of the lower surface of the first box cover when the first box cover lids over the box body.
The protruding portions can have a cross section with a trapezoid shape or an arch shape, and that shape can gradually narrow from bottom to top.
The elastomeric material of the lower surface of the first box cover could, by way of example and not limitation, be thermoplastic elastomer (TPE), thermoplastic polyurethane (TPU), or thermoplastic rubber (TPR), or any other elastomeric material except as the same may be expressly limited by the claims.
The lower surface of the first box cover could be a flat surface.
In certain embodiments, the powder box further comprises a second box body detachably disposed external to the first box body. There, a second box cover can be connected with the second box body to be capable of lidding over the first box cover.
Manifestations of the powder box can have a side of the first box body and a side of the first box cover hinged by a first hinge and a side of the second box body and a side of the second box cover hinged by a second hinge.
The second box body can be formed with a first containing groove for accommodating the first hinge and a second containing groove for accommodating the second hinge. The first containing groove and the second containing groove can be staggered from each other.
A plurality of first hook portions can be formed on the first box cover and can extend downward and be formed with hook feet. A plurality of first grooves corresponding in location and otherwise to the first hook portions can be formed on the first box body or between the first box body and the second box body. Moreover, at least one second hook portion can be formed on the second box cover and can extend downward and be formed with hook feet. At least one second groove corresponding in location and otherwise to the second hook portions can be formed on the second box body.
It is additionally possible for a containing space to be formed on the upper surface of the first box cover for receiving, for example, a powder puff.
Further, a mirror can be disposed, such as by fastening or otherwise, on the lower surface of the second box cover.
It will be understood that the above-mentioned orientation words, such as “front”, “back”, “left”, “right”, “over”, “on”, “upper”, “below”, “lower”, “downward”, “upward”, etc. are to define the orientation when the powder box is disposed upright for normal use. The powder box is disposed upright in, for example,
The scope of the present invention is not limited to the technical schemes formed by specific combination of the above-mentioned technical features.

For convenient use of the powder box, a containing space 5 is formed on the upper surface of the first box cover 2 for receiving a powder puff (not shown). A mirror 6 is fixed to the lower surface of the second box cover 4.
A side of the first box body 1 and a side of the first box cover 2 are hinged by a first hinge 7, and a side of the second box body 3 and a side of the second box cover 4 are hinged by a second hinge 8. The second box body 3 is formed with a first containing groove 9 for accommodating the first hinge 7 and a second containing groove 10 for accommodating the second hinge 8. The first containing groove 9 and the second containing groove 10 are staggered from each other such that interaction effects between the first box cover 2 and the second box cover 4 can be avoided, and the powder box is most convenient in use.
A plurality of first hook portions 11 is formed on the first box cover 2. The hook portions 11 extend downward and are formed with hook feet. A plurality of first grooves 12 matching with and corresponding in location and otherwise to the first hook portions 11 is formed on the first box body 1 or between the first box body 1 and the second box body 3. Specifically, the present embodiment of the powder box has three first hook portions 11, and the three first hook portions 11 and the first hinge 7 are evenly distributed over the periphery of the first box cover 2. Correspondingly, there are also three first grooves 12. Recesses are formed on the outer side of the first box body 1 and on the inner side of the second box body 3. The first grooves 12 are formed by the recesses on the first box body 1 and the recesses on the second box body 3 together. When closed, the first hook portions 11 and the first grooves 12 are mutually engaged and fastened.
At least one second hook portion 13 is formed on the second box cover 4. The hook portion or portions 13 extends downward and is formed with hook feet. At least one second groove 14 matching with the second hook portions 13 is formed on the second box body 3. In this embodiment, there is one second hook portion 13 and one the second groove 14, and the second hook portion 13 and the second hinge 8 are arranged at the two opposite sides of the powder box. When closed, the second hook portion 13 and the second groove 14 are mutually engaged and fastened.
For better sealing the first box body 1 and the second box body 2, a circle of a protruding portion 15 or protruding portions 15, such as a ridge or ridges, is formed on an upper surface of the first box body 1 and protrudes upwards. Preferably, the protruding portion 15 has a cross section with a trapezoid shape or an arch shape that gradually narrows from bottom to top. The lower surface of the first box cover 2 is a flat surface, at least in the portion thereof that aligns with the protruding portion 15, and the material thereof is an elastomeric material capable of elastic deformation. The material of the lower surface of the first box cover 2 can, by way of example and not limitation, be TPE, TPU or TPR. The protruding portion 15 contacts with the lower surface of the first box cover 2 and causes the elastic deformation of the lower surface of the first box cover 2 when the first box cover 2 lids over the first box body 1. Accordingly, a sealing space between the first box body 1 and the first box cover 2 is efficiently formed.
