Description
BACKGROUND OF INVENTION
[0001] I. Field of the Invention
[0002] This invention relating to the "protective structure of disc
packaging" presents a simple form of disc protecting structure
where placing the upper and lower layers of protection on the top
and bottom of the discs with the added wrapping of the
heat-shrinkable film and casing will prevent the deformation to the
discs due to direct contact with the heat-shrinkable film.
[0003] II. Description of the Prior Art
[0004] There are an increasing number of consumer electronic
products on the market that requires disc storage (such as CD,
CD-R, CD-RW, DVD, DVD-R, DVD+R and DVD-RW, etc.); generally, a
great quantity of blank discs are used either, by a computer disc
burner or a VCD/DVD+R/RW recorder and the packaging of those blank
discs are encased by some proper protective structures during the
packaging and delivery processes. Nevertheless, sensing that the
mounting hub manufactured for holding the disc media is 0.3 mm
thicker than the burning area, there are gaps between every two
discs when they are piled up together, to prevent the discs from
scratching. Therefore, the disc packaging methods on the market
presently are mostly done by piling up the discs, and then using a
heat-shrinkable film to directly encase the discs, or by using
other appropriate packing containers. Generally, there are two
frequently used packing containers described below:
[0005] 1) A cylindrical container, as shown in FIG. 1, comprises of
a cap-like upper lid a and a base b. A shaft, b1 is disposed
extensively from the center of the base b upwards for stringing
into a round hole c1 of a disc c in the center, thereby enabling a
pile of discs c to be positioned in a holding position. The base b
sets a groove b2 on the perimeter thereof corresponding to a buckle
a1 on the perimeter of the upper lid a. Upon using the container,
the round holes c1 in the center of the pile of the discs c, string
through the shaft c1 of the base b in sequence, and then the
container is covered with the upper lid a and the buckle a1 and the
groove b2 are wedged together, thereby enabling the pile of discs c
to be under the most complete protection. Such form of packaging is
made by way of plastic injection shaped with specific molding which
increases the manufacturing costs, resulting in higher unit selling
price. In turn such a packaging method incurs higher packaging
costs to disc manufacturers.
[0006] 2) A protective lid: As shown in FIG. 2, that the protective
lid d is of the same size as the diameter of the disc c. In
addition, the protective lid d has a side set with repeating rings
d1 in concentric circles, the plurality of ring portions d1
radially connect a plurality of supporting ribs d2, thereon; the
circle center of the protective lid sets a round hole d3
corresponding to the round hole c1 of the disc c in the center.
Upon the packaging of the discs, flat surfaces on one side of the
protective lid d are respectively placed on the top and bottom
sides of the pile of discs c, and subsequently, a heat-shrinkable
film encases both upper and lower sides of the protective lid d
with the pile of the discs c together. Such a form of packaging is
also made by the method of plastic injection, shaped with specific
molding which increases the manufacturing costs thou may be a
little bit lower in costs compared to the cylindrical container
manufacturing methods. Nevertheless, such a packaging method
enables the upper and the lower portions of the protective lid d
that are made of harder material, to directly press on any uneven
heat-shrinkable film on several discs c near to the protective lid
d such that there is no space in-between the pile of discs c, so as
to avoid any damage caused by friction between the discs c during
transport.
[0007] With reference to FIG. 3, the packing containers in
preceding paragraphs have its disadvantages and must be packed in
additional boxes to avoid packing bodies e from being damaged as a
result of disc collisions. At the same time to generally reduce the
box packing process, the packing bodies e are fixed by a plurality
of partition plates f made of corrugated paper, so that each
packing body e is independently placed in the space formed by those
partition plates f, so as to additionally manufacture each
partition plates f for packing individual disc container, thus
resulting in an increase of the disc packaging costs. In view of
the above, the invention provides a disc protective structure that
is composed of an upper lid, a lower lid and a casing being placed
on the top and bottom sides of the perimeters on a pile of discs,
and subsequently, a heat-shrinkable film is able to envelop the
protective body and the pile of discs. The protective body is made
of re-biodegradable corrugated paper and recyclable plastic
corrugated sheet with simplified structure. The advantage of the
invention includes easy-to-obtain materials at cheaper prices and
convenient manufacturing processes without additional packing boxes
required. In this way the invention is able to effectively reduce
the disc packaging costs based on the requirements of environmental
protection with the effect of completely protecting those
manufactured discs.
SUMMARY OF THE INVENTION
[0008] The primary objective of the present invention is to provide
a simplified protective structure with complete protection effect
for retaining the disc quality during the disc packaging and
transporting processes. In addition, this also meets the
requirement of environmental protection and effectively reducing
the disc packaging costs.
[0009] To achieve the above objective, the "protective structure of
disc packaging" of the present invention primarily comprises of an
upper lid, a lower lid and a casing, that are disposed on the top
and bottom sides of the perimeters round the pile of discs. The
upper lid and the lower lid are respectively composed of at least
two interlaced disc-shaped plates, which possess wavy buffer
portions that are made of corrugated paper or plastic corrugated
sheet. When the upper and the lower disc-shaped plates are
disposed, the undulating buffer portions of the disc-shaped plates
are vertically stacked up, in addition, the sizes of the
disc-shaped plates are larger than the sizes of the discs causing
the casing to be shaped in a roll.
[0010] Upon the disc packaging, first of all, the invention enables
the discs to be piled up, where the lower lid of the invention is
placed on the bottom side of the pile of discs, and the casing
sleeves over the perimeters of the discs as well as the upper lid
being placed on the upper side of the discs. Subsequently, a
heat-shrinkable film covers the upper lid perimeter, including the
discs to the lower lid perimeter including the bottom of the discs
for completion of the disc packaging. The buffered portions on the
upper lid, the lower lid and the casing are able to absorb any
unevenness in the heat-shrinkable film such that the discs
contained within the upper lid, the lower lid and the casing are
tightly packed to them without gaps in-between. Extra box packing
process is not required, so as to reduce conventional use of
packing boxes and partition plates where the discs contained within
are not directly pressed by the force, resulting in the damage to
those discs because of the space shrinking in-between the discs.
Therefore, the invention is able to achieve the objective of
retaining the disc quality during the disc packaging and delivery
processes. Furthermore, the said protective body of the invention
is made of biodegradable corrugated paper and recyclable plastic
corrugated sheet with simplified structure. Accordingly, the
advantages of the invention also include easily obtainable
materials at cheaper prices and more convenient manufacturing
processes, so that the invention is able to effectively reduce the
disc packaging costs based on the requirement of environmental
protection with the effect of completely protecting the
manufactured discs.
