Description
TECHNICAL FIELD
[0001] The present invention relates to a combination of a piece of
transparent resin and a paper cover sheet and a coupling method
thereof, and more particularly, to a combination of a piece of
transparent resin and a paper cover sheet which are used to package
a finished product so that the packaged product can be seen from
the outside with the naked eye, and a coupling method thereof.
BACKGROUND ART
[0002] In general, as a way of packaging a finished small-sized
product, a method of applying an adhesive to the upper and lower
surfaces of a paper box or taping the paper box after putting the
product in the paper box is frequently used.
[0003] This method is widely used when packaging consumer products
and food items. In this regard, a product tends to be packaged
using a case made of a transparent material and then displayed or
placed on sale so that the display effect can be improved and
consumers' desire to directly check the condition of the product
with the naked eye can be satisfied.
[0004] For example, FIGS. 1a and 1b are schematic views
illustrating conventional methods for coupling a piece of
transparent resin and a paper cover sheet. Referring to FIG. 1a,
after applying an adhesive 40 onto the peripheral portions of a
paper cover sheet 20, products 30 are received in the receiving
space defined in the piece of transparent resin 10. Then, with the
paper cover sheet 20 placed so as to cover the receiving space of
the piece of transparent resin 10, by pressing the piece of
transparent resin 10 and the paper cover sheet 20 to each other
while radiating heat, high frequency radiation, or the like on the
adhesive 40, the piece of transparent resin 10 and the paper cover
sheet 20 are bonded with each other.
[0005] However, in this conventional method, when the package is
opened, since some of the peripheral portions of the paper cover
sheet 20 adhere to the lower surface of the marginal portions 11 of
the piece of transparent resin 10, a problem is caused in that the
transparent resin 10 cannot be properly recycled, and is likely to
be disposed as waste.
[0006] Also, referring to FIG. 1b, in another method, marginal
portions 51 are formed on both sides of a piece of transparent
resin 50. The marginal portions 51 are folded to define guide
spaces therein. After products 60 are received in the receiving
space defined in the piece of transparent resin 50, a paper cover
sheet 70 is inserted into the guide spaces in such a way as to
cover the receiving space. In this state, the piece of transparent
resin 50 and the paper cover sheet 70 are fastened to each other
using staples 80.
[0007] Nevertheless, in this conventional method, when a customer
purchases and opens a package, the customer's finger is likely to
be injured by the staples 80. In particular, in the case where the
staples 80 are improperly folded and the pointed ends of the
staples 80 are exposed to the outside, the likelihood of the
customer's finger being injured increases while handling the
package.

MODE FOR THE INVENTION
[0023] Reference will now be made in greater detail to preferred
embodiments of the invention, examples of which are illustrated in
the accompanying drawings. FIG. 3 is an exploded perspective view
illustrating a combination of a piece of transparent resin and a
paper cover sheet in accordance with an embodiment of the present
invention, and FIGS. 4a and 4b are sectional views illustrating a
process for coupling the piece of transparent resin and the paper
cover sheet in accordance with the embodiment of the present
invention.
[0024] The present invention relates to a packaging member which is
composed of a piece of transparent resin and a paper cover sheet
and is used to package products. In detail, the present invention
relates to a method for coupling a piece of transparent resin and a
paper cover sheet, and a packaging member formed by the method.
[0025] As described above, in the conventional coupling methods, an
adhesive is applied between the transparent resin and the paper
cover sheet, which are then pressed to be bonded with each other,
or the transparent resin and the paper cover sheet are fastened to
each other using staples. In the case in which the adhesive is
used, when a package is opened, portions of the paper cover sheet
adhere to the transparent resin. As a consequence, a problem is
caused in that the transparent resin is disposed of as waste rather
than being recycled, which leads to the waste of resources.
Further, in the case of using the staples, a customer's finger is
likely to be injured by the pointed ends of the staples when
opening a package, and inconvenience is caused in that the staples
must be separately recycled.
[0026] Referring to FIG. 3, a combination 100 of a piece of
transparent resin and a paper cover sheet in accordance with an
embodiment of the present invention is used to package products 200
such as consumer products and food items. The combination 100 is
composed of a piece of transparent resin 110 which is formed to
correspond to the size and the shape of the products 200, and a
paper cover sheet 120 which covers the receiving space 101 (see
FIG. 4) defined in the piece of transparent resin 110.
[0027] The piece of transparent resin 110 is formed such that the
receiving space 101 is defined in the center of the piece of
transparent resin 110. Marginal portions 111 are formed on the
periphery of the center portion of the piece of transparent resin
110. The marginal portions 111 are folded inward such that upper
and lower bonding parts 111a and 111b are formed, and guide spaces,
through which the paper cover sheet 120 is inserted, are defined
between the upper and lower bonding parts 111a and 111b.
[0028] Preferably, embossments 111a' are formed in the upper and
lower bonding parts 111a and 111b of the marginal portions 111 at
positions corresponding to the through-holes 121 in the paper cover
sheet 120, which will be described later, such that the embossments
111a' project inward. This is to ensure easy bonding of the
transparent resin 110 and the paper cover sheet 120 after the paper
cover sheet 120 is inserted into the guide spaces defined between
the upper and lower bonding parts 111a and 111b.
[0029] Meanwhile, the paper cover sheet 120 can be printed on the
surfaces thereof with the specification of the products, the logo
of a manufacturing company, etc. The paper cover sheet 120 is
inserted into the guide spaces, which are defined by the upper and
lower bonding parts 111a and 111b of the marginal portions 111 of
the piece of transparent resin 110, and closes the receiving space
in the piece of transparent resin 110.
[0030] One or more through-holes 121 are defined through the
peripheral portions of the paper cover sheet 120. After the paper
cover sheet 120 is inserted into the guide spaces in the piece of
transparent resin 110, the upper bonding part 111a and the lower
bonding part 111b of the marginal portions 111 of the piece of
transparent resin 110 are bonded with each other through the
through-holes 121 in the paper cover sheet 120.
[0031] It is preferred that one through-hole 121 be defined in each
peripheral portion of the paper cover sheet 120. An appropriate
number of through-holes 121 may be defined in each peripheral
portion of the paper cover sheet 120 depending upon the size of the
products 200. A device for defining the through-holes 121 can
comprise a conventional punching machine, or a dedicated punching
machine can be fabricated. Since the punching machine is beyond the
technical scope of the present invention, a detailed description
thereof will be omitted herein.
[0032] Meanwhile, preferably, the upper and lower bonding parts
111a and 111b of the piece of transparent resin 110 are heat-fused
to each other through the through-holes 121 in the paper cover
sheet 120 by applying heat and pressing them to each other. This is
made possible based on the fact that synthetic resin has a low
melting point due to the thermo-chemical characteristics
thereof.
[0033] The piece of transparent resin 110 and the paper cover sheet
120 can be bonded with each other not only by heat-fusion but also
by using a bonding mechanism (not shown) which employs ultrasonic
waves, high frequency radiation, or the like. At this time, the
bonding mechanism has protuberances which can pass through the
through-holes 121 in the paper cover sheet 120, such that the
protuberances can be inserted into the embossments 111a' formed in
the marginal portions 111 of the piece of transparent resin 110 so
as to bond the upper and lower bonding parts 111a and 111b of the
piece of transparent resin 110.
[0034] When the process for coupling the piece of transparent resin
110 and the paper cover sheet 120 is completed, the upper and lower
bonding parts 111a and 111b of the piece of transparent resin 110
are bonded with each other through the through-holes 121 in the
paper cover sheet 120, by which the packaging of the products 200
is conducted.
[0035] As a consequence, due to the fact that only the upper and
lower bonding parts 111a and 111b of the marginal portions 111 of
the piece of transparent resin 110 are bonded with each other
through the through-holes 121 of the paper cover sheet 120, when
the package of the products 200 is opened, since only the upper and
lower bonding parts 111a and 111b are detached from each other, it
is possible to prevent portions of the paper cover sheet 120 from
adhering to the transparent resin 110, whereby the opening of the
package can be simply performed.
[0036] Hereafter, a method for coupling the piece of transparent
resin 110 and the paper cover sheet 120 constituting the
combination 100 constructed as mentioned above will be described.
FIG. 5 is a flow chart illustrating a method for coupling a piece
of transparent resin and a paper cover sheet in accordance with
another embodiment of the present invention.
[0037] Referring to FIG. 5, in the method for coupling the piece of
transparent resin 110 and the paper cover sheet 120 with each
other, first, the marginal portions 111 of the piece of transparent
resin 110 are folded inward to define the upper and lower bonding
parts 111a and 111b, and the embossments 111a' are formed in at
least one of the upper and lower bonding parts 111a and 111b to
project inward (S10). Then, one or more through-holes 121 is
punched in the peripheral portions of the paper cover sheet 120
(S20).
[0038] Next, the products 200 are received in the receiving space
defined in the piece of transparent resin 110, and the paper cover
sheet 120 is inserted between the upper and lower bonding parts
111a and 111b of the marginal portions 111 of the piece of
transparent resin 110 (S30).
[0039] Finally, the upper and lower bonding parts 111a and 111b of
the marginal portions 111 of the piece of transparent resin 110 are
heat-fused to each other through the through-holes 121 in the paper
cover sheet 120, whereby the combination 100 of the piece of
transparent resin 110 and the paper cover sheet 120 is completely
formed (S40).
[0040] The combination 100 of the piece of transparent resin 110
and the paper cover sheet 120, which are bonded in this way,
provides advantages in that the finish of the bonded portions is
clean, and when the piece of transparent resin 110 and the paper
cover sheet 120 are decoupled from each other, since no portions of
the paper cover sheet 120 adhere to the marginal portions 111 of
the piece of transparent resin 110, the transparent resin 110 can
be properly recycled.
