Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates generally to a packing box,
and more particularly to a snap hinge compact.
[0003] 2. The Prior Arts
[0004] Currently, a typical conventional compact is mainly
constituted of an upper cover and a box body. The upper cover and
the box body are usually coupled together at one side by a
hinge.
[0005] For example, China patent application No. 200820048517.8
discloses a flip-type compact. The flip-type compact includes an
upper cover and a box body. The upper cover includes a hinge slot
configured at one side of the upper cover. The box body includes a
recessive slot adapted for correspondingly matching with the hinge
slot. The box body further includes a hinge shaft coupled to each
of two sides of an inner wall of the recessive slot for coupling
with the hinge slot. The hinge shaft is rotatably coupled with the
hinge slot so as to couple the upper cover to the box body. In such
a way, the upper cover is allowed to rotate around the hinge shaft
so as to open or close the compact.
[0006] However, in accordance with such a design, only one end of
the hinge shaft is secured to the inner wall of the recessive slot,
while the other end of the hinge shaft is a free end. Therefore,
the hinge shaft has a low strength against pulling force. When the
hinge slot is being engaged with the hinge shaft or the upper cover
is turned to rotate around the hinge shaft, the hinge shaft is
likely to be broken.
SUMMARY OF THE INVENTION
[0007] Accordingly, a primary objective of the present invention is
to provide a snap hinge compact including a hinge shaft. The hinge
shaft has two ends, and both of the two ends of the hinge shaft are
secured to the inner wall of the recessive slot, so as to improve
the strength of the hinge shaft, and extending the lifespan of the
snap hinge compact.
[0008] For achieving the foregoing objective, the present invention
provides a snap hinge compact. The snap hinge compact includes an
upper cover and a box body. The upper cover includes a hinge slot
configured at one side of the upper cover. The box body includes a
recessive slot adapted for correspondingly matching with the hinge
slot. The box body includes a hinge shaft disposed in the recessive
slot for engaging with the hinge slot. The hinge shaft is rotatably
coupled with the hinge slot. The hinge shaft has two ends secured
to two sides of an inner wall of the recessive slot,
respectively.
[0009] According to an embodiment of the present invention, an
inner wall of the hinge slot includes an outwardly declining
surface, an inwardly recessive arcuate surface, and a flat surface.
The outwardly declining surface is positioned at an outside of the
inwardly recessive arcuate surface, and the flat surface is
positioned at an inside of the inwardly recessive arcuate
surface.
[0010] According to an embodiment of the present invention, the box
body includes an accommodating region for containing cosmetics
therein.
[0011] According to an embodiment of the present invention, the
upper cover further includes a protrusion member disposed at
another side of the upper cover opposite to where the hinge slot is
positioned. The box body further includes a receiving slot
positioned at another side of the box body opposite to where the
recessive slot is positioned for correspondingly matching with the
protrusion member. The protrusion member includes a first engaging
block and the box body further includes a second engaging block
configured in the receiving slot corresponding to the first
engaging block.
[0012] According to a further embodiment of the present invention,
the box body includes a projecting edge adapted for engaging with a
bottom of the upper cover.
[0013] Generally, the present invention provides a snap hinge
compact including an upper cover and a box body. The upper cover
includes a hinge slot disposed at one side of the upper cover. The
box body includes a recessive slot adapted for correspondingly
matching with the hinge slot. The box body includes a hinge shaft
disposed in the recessive slot for engaging with the hinge slot.
The hinge shaft is rotatably coupled with the hinge slot. The hinge
shaft has two ends secured to two sides of an inner wall of the
recessive slot, respectively. In operation, since both of the two
ends of the hinge shaft are secured to the inner wall of the
recessive slot, the hinge shaft has two pivot points, so that
comparing with the conventional snap hinge compact as discussed
above, the hinge shaft of the snap hinge compact of the present
invention achieves an improved strength. Therefore, when the hinge
slot is engaged with the hinge shaft or the upper cover is turned
to rotate around the hinge shaft, the hinge shaft is not likely to
be broken.
BRIEF DESCRIPTION OF THE DRAWINGS
[0014] The present invention will be apparent to those skilled in
the art by reading the following detailed description of preferred
embodiments thereof, with reference to the attached drawings, in
which:
[0015] FIG. 1 is a perspective view of a snap hinge compact
according to an embodiment of the present invention;
[0016] FIG. 2 is a perspective view of an upper cover of the snap
hinge compact according to an embodiment of the present invention;
and
[0017] FIG. 3 is a perspective view of a box body of the snap hinge
compact according to an embodiment of the present invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0018] The accompanying drawings are included to provide a further
understanding of the invention, and are incorporated in and
constitute a part of this specification. The drawing illustrates
embodiments of the invention and, together with the description,
serves to explain the principles of the invention.
[0019] FIG. 1 is a perspective view of a snap hinge compact
according to an embodiment of the present invention. FIG. 2 is a
perspective view of an upper cover of the snap hinge compact
according to an embodiment of the present invention. FIG. 3 is a
perspective view of a box body of the snap hinge compact according
to an embodiment of the present invention.
[0020] Referring to FIGS. 1 through 3, the present invention
provides a snap hinge compact including an upper cover 1 and a box
body 2. The upper cover 1 includes a hinge slot 11 positioned at
one side of the upper cover 1. The box body 2 includes a recessive
slot 21 at one side of the box body 2 adapted for correspondingly
matching with the hinge slot 11. The box body 2 further includes a
hinge shaft 22 positioned in the recessive slot 21. The hinge shaft
22 is adapted for being engaged with the hinge slot 11 of the upper
cover 1. The hinge shaft 22 is rotatably coupled with the hinge
slot 11. The hinge shaft 22 has two ends secured to two sides of an
inner wall of the recessive slot 21, respectively.
[0021] In operation, because both of the two ends of the hinge
shaft 22 are secured to the inner wall of the recessive slot 21,
the hinge shaft 22 has two pivot points, so that comparing with the
conventional snap hinge compact as discussed above, the hinge shaft
22 of the snap hinge compact of the present invention achieves an
improved strength. Therefore, when the hinge slot 11 is engaged
with the hinge shaft 22 or the upper cover 1 is turned to rotate
around the hinge shaft 22, the hinge shaft 22 is not likely to be
broken, thus extending the lifespan of the snap hinge compact.
According to other embodiments, the snap hinge compact may include
more or less hinge shafts 22 than that is shown in the
drawings.
[0022] According to an embodiment of the present invention, as
shown in FIG. 2, each hinge slot 11 includes two opposite inner
walls symmetrically disposed. Each inner wall of the hinge slot 11
includes an outwardly declining surface 111, an inwardly recessive
arcuate surface 112, and a flat surface 113. The outwardly
declining surface 111 is positioned at an outside of the inwardly
recessive arcuate surface 112, and the flat surface 113 is
positioned at an inside of the inwardly recessive arcuate surface
112. As shown in FIG. 2, since the two inner walls of the hinge
slot 11 are oppositely disposed, the two outwardly declining
surface 111 of the two inner walls of the hinge slot 11 are
positioned such that the hinge shaft 22 can be conveniently
assembled to hinge slot 11. Similarly, the two inwardly recessive
arcuate surfaces 112 defines a space allowing the hinge shaft 22 to
rotate thereby, so that the upper cover 1 is allowed to rotate
around the hinge shaft 22 and relative to the box body 2. Likewise,
the hinge shaft 22 is also allowed to be removed out from the hinge
slot 11.
[0023] According to an embodiment of the present invention, the box
body 2 includes a plurality of accommodating regions 23 for
containing cosmetics therein.
[0024] According to an embodiment of the present invention, the
upper cover 1 further includes a protrusion member 12 disposed at
another side of the upper cover 1 opposite to where the hinge slot
11 is positioned. The box body 2 further includes a receiving slot
24 positioned at another side of the box body 2 opposite to where
the recessive slot 21 is positioned for correspondingly matching
with the protrusion member 12. The protrusion member 12 includes a
first engaging block 121 and the box body 2 further includes a
second engaging block 241 configured in the receiving slot 24
corresponding to the first engaging block 121. The first engaging
block 121 can be engaged with the second engaging block 241. When
the first engaging block 121 is engaged with the second engaging
block 241, the upper cover 1 is closed to the box body 2. According
to a further embodiment of the present invention, the box body 2
includes a projecting edge 25 adapted for engaging with a bottom of
the upper cover. In such a way, the upper cover 1 and the box body
2 can be closed more tightly.
[0025] Although the present invention has been described with
reference to the preferred embodiments thereof, it is apparent to
those skilled in the art that a variety of modifications and
changes may be made without departing from the scope of the present
invention which is intended to be defined by the appended
claims.
