Structure of Packing Material Inflated With Air
Abstract
Disclosed is a structure of a packing material inflated with
air. Conventionally, the packing material inflated with air has a
bad appearance due to protrusions formed at opposite sides of a
lower end of its body, as well as generates a gap between its
bodies when stacked in a storage box, and thus fails to allow the
loading of a great deal of products in the storage box. The
disclosed packing material inflated with air is formed so as to
prevent the opposite side of the lower end of its body from
protruding when spread, thereby creating beauty in appearance.
Further, when a lot of the disclosed packing materials are stacked
in the storage box, they are brought into close contact with each
other, so that more products can be stably loaded in the storage
box.

Description
TECHNICAL FIELD
[0001] The present invention relates to a structure of packing
material inflated with air, and more particularly to a structure of
packing material inflated with air, capable of, when the packing
material is spread by air injection, preventing opposite sides of a
lower end of a packing material's body from protruding to improve
appearance of the packing material for its own sake, as well as,
when a plurality of packing materials are stacked in a storage box,
bringing the packing materials into close contact with each other
to stably load more products in the storage box.
BACKGROUND ART
[0002] In general, packing materials has been used to prevent a
finished product from being damaged by shock or scratch. Such
packing materials must generally have light weight, and a certain
degree of cushion and strength because they are held in a storage
box together with the product. Conventionally, Styrofoam,
corrugated cardboards, air gap bags, and the like have been used as
the packing materials, but they have low functionality for the
following reasons that it is difficult to process them in
correspondence with various products, that they have low capability
of absorbing and offsetting shock, and that they are not modified
and used in a desired form when they are stored with a small volume
and then packed with the product. In order to solve this problem, a
packing material inflated with air, a so-called air packing box,
has been used recently, which is adapted to further improve its
function and to allow the product to be more stably protected from
shock, scratch, and the like. The air packing box takes a desired
shape by supplying itself with air using a separate air pump. The
product is enclosed and packed by the air packing box, thereby
being protected from being damaged by shock, scratch, and so on.
This air packing box is spread by air supplied on opposite sides of
a lower end of its body when inflated, and in the meantime
protrudes outside its periphery. When the air packing boxes are
stacked in a storage box together with products, protrusions of the
opposite sides of the lower end of its body are brought into
contact with each other, thus generating a gap between the air
packing box bodies. Due to these protrusions, each air packing box
provides bad appearance. Furthermore, due to the gap generated by
the protrusions, several products are not loaded in one storage box
when the air packing boxes are stacked in the storage box.
DISCLOSURE OF INVENTION
Technical Problem
[0003] Therefore, the present invention has been made in view of
the above-mentioned problems, and it is an objective of the present
invention to provide a structure of a packing material inflated
with air, capable of, when the packing material is spread by air
injection, preventing opposite sides of a lower end of a packing
material's body from protruding so as to improve the appearance of
the packing material, as well as, when a plurality of packing
materials are stacked in a storage box, bringing the packing
materials into close contact with each other to stably load more
products in the storage box.
Technical Solution
[0004] According to an aspect of the present invention, there is
provided a structure of a packing material inflated with air, which
is characterized in that cutout sections are formed at opposite
sides of a lower end of a packing material's body, and adhesion
surfaces located between two air pockets adjacent to the cutout
sections are formed with guide holes so as to be supplied with air
from other air pockets. Thereby, when the packing material is
spread by injection of air, the opposite sides of the lower end of
the packing material's body are prevented from protruding outside a
circumference of the body, so that when a plurality of packing
materials are stacked in a storage box, the packing materials are
stacked so as to be brought into close contact with each other, and
that more products can be stably loaded in the storage box,
compared to a conventional packing material inflated with air.
ADVANTAGEOUS EFFECTS
[0005] According to the present invention, when the packing
material is spread by injection of air, the opposite sides of the
lower end of the packing material's body are prevented from
protruding, so that when a plurality of packing materials are
stacked in a storage box, the packing materials are brought into
close contact with each other, and thereby more products can be
stably loaded in the storage box, and the packing material can be
improved in its own appearance.

BEST MODE FOR CARRYING OUT THE INVENTION
[0011] Reference will now be made in detail to the preferred
embodiments of the present invention. The present invention
provides a structure of a packing material inflated with air, which
includes a pocket-like body (4) forming a plurality of air pockets
(10) partitioned by adhesion surfaces (8) along a circumference
thereof and opened at an upper portion thereof, an injection
section (14) formed on one side of the body (4) and provided with
an injection hole (12), an air passage (16) connected to the
injection hole (12) and transversely disposed in the body (4),
valves (18) connected to the air passage (16) and installed in the
air pockets (10), and a cover (16) integrally extending from a rear
upper end of the body (4) and formed so as to connect a plurality
of air pockets (10) partitioned by the adhesion surfaces (8) to the
air pockets (10) of the body (4), wherein the body (4) is formed
with cutout sections (24) on opposite sides of a lower end thereof.
Further, the adhesion surfaces (8) located on opposite sides of the
front of the body (4) and between two of the air pockets (10)
adjacent to the cutout sections (24) may be formed with guide holes
(25), which pass through the adhesion surfaces (8) and are adapted
to be supplied with air from other air pockets (10). Referring to
FIGS. 1 through 4, first, an air packing box 2 adapted to hold a
product is comprised of a pocket-like body 4 an upper portion of
which is opened, and a cover 6 that integrally extends from a rear
upper end of the body 4 (see FIG. 1). The air packing box 2 can be
manufactured such that it is modified to a desired form according
to a shape of the product to be packed. The body 4 includes a
plurality of air pockets 10, which are partitioned and transversely
arranged by adhesion surfaces 8 formed by high-frequency heating of
internal and external packing films. The body 4 is formed with an
injection section 14, which extends from one side of the body 4 and
has an injection hole 12, so as to be capable of connecting a pump
not shown. The injection section 14 is connected with an air
passage 16 guiding a flow of air, and is disposed on the adhesion
surface 8 located in the rear middle of the body 4 (see FIG. 4).
The air passage 16 is provided with valves 18 (see FIG. 3), each of
which controls the flow of air and is disposed in each air pocket
10 along a lengthwise direction at uniform intervals. The body 4 is
formed at the rear upper end thereof with the cover 6, which
integrally extends so as to allow a product to be protected from
shock (see FIG. 3). The cover 6 is provided with the same air
pockets 10, which are connected to the air pockets 10 formed at the
body 4, and are partitioned and transversely arranged by the
adhesion surfaces 8. Each air pocket 10 of the body 4 is formed in
the middle thereof with bending adhesion surfaces 20, which allow a
bottom 19 to be formed between front and rear lower portions of the
body 4 when the air packing box is inflated with air to have a
desired form. Each air pocket 10 of the cover 6 is formed with a
bending adhesion surface 22, which allows the cover 6 to be folded
at the rear upper end of the body 4. In this manner, at the front
of the body 4, the air pockets 10, which are integrally connected
to the air pockets 10 formed in the rear of the body 4, are
partitioned and transversely arranged by the adhesion surfaces 8.
Here, the air pockets 10, which are located at opposite sides of
the front of the body 4, are separated from the air pockets 10,
which are located at opposite sides of the rear of the body 4, by
cutout sections 24, thus failing to be supplied with air from the
valves 18. In order to solve this problem, the adhesion surfaces 8,
which are located on opposite sides of the front of the body 4 and
between two of the air pockets 10 adjacent to the cutout sections
24, are provided with guide holes 25, which pass through the
adhesion surfaces 8 and allow the air supplied through the valves
18 to flow into the last air pockets 10 (see FIG. 2). Accordingly,
the guide holes 25 cause the air pockets 10 with and without the
built-in valves 18 to be connected to allow the air to flow to each
other. The body 4, the cover 6, and the valves 18 can be made by
selectively employing a plastic sheet, a vinyl sheet, a nylon film,
a polyethylene film, and the like. Meanwhile, the opposite sides of
the lower end of the body 4 are each cut out at 90 degrees by a
predetermined size, thereby forming the cutout sections 24, which
prevent corners of the lower end of the body 4 from protruding
outside when the air packing box 2 takes a desired form by air
injection. At this time, the cutout sections 24 may be concavely
formed without being cut out at 90 degrees, or take another desired
form. An operation of the present invention constructed as
described above will be described below. First, when the pump (not
shown) is driven after being connected to the injection hole 12 of
the injection section 14 (see FIG. 2), compressed air flows along
the air passage 16 through the injection hole 12 to the air pockets
10 individually divided through the valves 18. The air pockets 10
are inflated in a bulged form at a pre-determined pressure by the
continuously supplied air, and simultaneously the air packing box 2
is spread to have a shape similar to a product. At this time, a
part of the air supplied to the second air pockets 10 located on
the opposite sides of the body 4 flows to and inflates the last air
pockets 10 located on the sides of the opposite cutout sections 24.
In this manner, the air flowing into the air pockets 10 remains in
the air pockets 10 without leakage to the outside because the
valves 18 close by themselves due to air pressure. In this state,
when external shock is applied to the air packing box 2, the air
filled in the air pockets 10 serves as a cushion, thus absorbing
and offsetting the external shock. As such, the shock is
interrupted by the air pockets 10, and thus is not transmitted to
the inside of the air packing box 2. The spread body 4 as described
above has opposite upper and lower portions, which abut on the
bending adhesion surfaces 20, formed as sidewalls and the bottom
19, respectively. At this time, the cutout sections 24 formed on
the opposite sides of the lower end of the body 4 are spread, and
in the meantime, edges of the air pockets defining each cutout
section 24 move toward each other. Therefore, when the air packing
box 2 is spread by the injected air, the opposite sides of the
lower end of the body 4 take the form of a straight line without
protruding outside. In this state, when the product is placed into
the air packing box 2, the body 4 is further spread out. Hence, the
edges of the air pockets defining the cutout sections 24 formed on
the opposite sides of the lower end of the body 4 further approach
each other. Afterwards, when the cover 6 is pushed aside with the
bending adhesion surfaces 22 adopted as a boundary, the cover 6
closes the upper portion of the body 4, thereby covering an upper
end of the product. Accordingly, the air packing box 2 is in a
state of completing packing. These air packing boxes 2 are input
and stacked in a storage box (not shown). In this case, these air
packing boxes 2 are loaded in a longitudinal and transverse
arrangement in close contact with each other because each of them
has no protrusion outside its periphery.
INDUSTRIAL APPLICABILITY
[0012] According to the present invention, the packing material
inflated with air is improved so as to provide no protrusion
outside its periphery due to the cutout sections formed on the
opposite sides of the lower end of the air packing box body when
the air packing box is spread by air, wherein a plurality of air
packing boxes are stacked in close contact with each other when
stacked in one storage box, so that more products can be stably
loaded in the storage box. Further, the packing material inflated
with air of the present invention can be applied to any packing
material inflated with air that is used as a shock-absorbing means
when packing the product by inflating it with the supplied air.
While this invention has been described in connection with what is
presently considered to be the most practical and preferred
embodiment, it is to be understood that the invention is not
limited to the disclosed embodiment and the drawings, but, on the
contrary, it is intended to cover various modifications and
variations within the spirit and scope of the appended claims.
