Packaging box

The present invention relates to a packaging box including: a main body having at least an upper surface and an inner space; and a handle disposed on the upper surface of the main body, wherein the upper surface is disposed to be dented inwardly so as to be apart from the handle. The packaging box has the folding line formed on the upper surface so as to make the upper surface dented inwardly by the user's pressing and make the upper surface and the handle spaced apart from each other such that the user can easily insert his or her finger therebetween, thereby remarkably improving user convenience. The packaging box sufficiently shields the inner space from the outside because the upper surface maintains sealing force when the upper surface is dented in order to form the finger insertion space, thereby effectively preventing the inflow of contaminants so as to maximize user satisfaction.

RELATED APPLICATIONS

This application is a 35 U.S.C. § 371 national phase application of PCT/KR2015/012793 (WO 2016/085273), filed on Nov. 26, 2015, entitled “Packaging box”, which application claims the benefit of Korean Utility Model No. KR 20-2014-0008727, filed Nov. 27, 2014, which is incorporated herein by reference in its entirety.

TECHNICAL FIELD

The present invention relates to a packaging box, and more particularly, to a packaging box which can maintain sealability of an inner space and enables a user to easily hold a handle.

BACKGROUND ART

In general, in order to carry various things, such as fruits or crops, at once, a box of a cuboidal shape is utilized. The box is in the state that a lower surface and a side surface are sealed and an upper surface is open. After things are put in the box, the box may be carried after the upper surface is sealed.

In this instance, a user moves the box while holding the lower surface of the box with both hands after lifting up the box of the cuboidal shape. However, if the box is bulky or things put in the box are very heavy, it may cause great inconvenience in lifting the box as described above.

Therefore, conventionally, a box has a handle. For example, the box generally has a band, which is capable of maintaining sealability of the box and preventing separation of the contents and is capable of being utilized as a handle. In this instance, most of the bands are polypropylene bands because they must have elasticity, tensile force, corrosion resistance, thermal resistance, safety and environmental friendliness.

However, because the band is disposed wrapping the outer surface of the box, if the band is disposed tightly, the band presses against one side of the box. In this instance, because the user must put his or her finger between the band and the side of the box while forcibly opening a gap between the band and the side of the box and the user's finger may be pressed between the band and the side of the box if the band is lacking in elastic force, there is a danger of causing an accident.

In order to solve such a problem, an attempt to form a hole at one side of the box to insert the user's finger into the hole without using the band has been made. However, because the inner space of the box is communicated with the outside because of the hole, the contents stored in the box may be contaminated or get damaged.

DISCLOSURE

Technical Problem

Accordingly, the present invention has been made in view of the above-mentioned problems occurring in the prior art, and it is an object of the present invention to provide a packaging box, which includes an upper surface formed to be dented inwardly, a handle provided at the upper surface, and a finger insertion space naturally formed between the handle and the upper surface, thereby enabling a user to easily hold the handle through the finger insertion space.

It is another object of the present invention to provide a packaging box, of which the upper surface is dented inwardly while maintaining sealability even though the finger insertion space formed, thereby preventing foreign contaminant matters from infiltrating into the contents stored in the box.

Technical Solution

To accomplish the above object, according to the present invention, there is provided a packaging box including: a main body having at least an upper surface and an inner space; and a handle disposed on the upper surface of the main body, wherein the upper surface is disposed to be dented inwardly so as to be apart from the handle.

In detail, the upper surface is dented inwardly while sealing the inner space of the main body.

Moreover, the handle has a band form to surround the main body.

Furthermore, the upper surface includes a pair of foldable parts respectively having folding lines.

Additionally, the upper surface further includes a connection part for connecting the foldable parts with each other.

In addition, the folding lines are bilaterally symmetric and are disposed to be collected from the outer part of the upper surface to the middle part of the upper surface.

Furthermore, the main body includes a side surface extending downwardly from the upper surface, and a lower surface disposed at the bottom of the side surface.

Advantageous Effects

As described above, the packaging box according to an embodiment of the present invention has the folding line formed on the upper surface so as to make the upper surface dented inwardly by the user's pressing and make the upper surface and the handle spaced apart from each other such that the user can easily insert his or her finger therebetween, thereby remarkably improving user convenience.

Moreover, the packaging box according to an embodiment of the present invention may sufficiently shield the inner space from the outside because the upper surface can maintain sealing force when the upper surface is dented in order to form the finger insertion space, thereby effectively preventing the inflow of contaminants so as to maximize user satisfaction.

MODE FOR INVENTION

The above and other objects, features and other advantages of the present invention will be more clearly understood from the following detailed description when taken in conjunction with the accompanying drawings. In the following description, the same elements will be designated by the same reference numerals although they are shown in different drawings. Further, in the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

FIGS. 1 and 2are top views of a packaging box according to a preferred embodiment of the present invention,FIG. 3is a perspective view of the packaging box according to the preferred embodiment of the present invention, andFIG. 4is a side sectional view of the packaging box. In this instance,FIG. 1illustrates a state of the packaging box before an upper surface11is dented, andFIG. 2illustrates a state of the packaging box after the upper surface11is dented.

FIG. 5is a planar figure of the packaging box.

Referring toFIGS. 1 to 5, the packaging box1according to the preferred embodiment of the present invention includes a main body10and a handle20.

The main body10includes at least an upper surface11and has an inner space. The main body10may include not only the upper surface11but also a side surface12and a lower surface13, and the side surface12extends downwardly from the upper surface11and the lower surface13is disposed at the bottom of the side surface12.

Therefore, the main body10may be formed in a cuboid and may store various things in the inner space formed therein. In this instance, the things stored in the inner space of the main body10are not restricted in forms or kinds thereof.

Of course, besides the main body10may have one of various shapes, such as a cuboid, an octagonal pillar, a cylinder, a sphere and so on. In case of the main body10of a spherical shape, the upper surface11may be formed in a curved form, and in this instance, the handle20may be disposed to get, in close contact with at least, a part of the upper surface11.

The main body10may be made of a material like paper or other various materials, such as plastic or metal. Preferably, the main body10is made of a material which is not torn or broken even though it is folded along a folding line111, which will be described later.

The upper surface11of the main body10may be disposed to be dented inwardly. The upper surface11has the handle20, and the handle20is disposed to get in close contact with the upper surface11. When the upper surface11is dented inwardly, the upper surface11may be spaced apart from the handle20.

In this instance, a space between the upper surface11and the handle20may be defined as a finger insertion space15. A user grasps the handle20to easily lift up the packaging box1after putting his or her finger2into the finger insertion space15formed between the dented upper surface11and the handle20.

The upper surface11is dented in the direction to be apart from the handle20and may be dented downwardly as seen in theFIG. 4. In this instance, the upper surface11may be dented inwardly while sealing the inner space14of the main body10. That is, the upper surface11is not torn or does not form any hole while being dented. For this, the upper surface11has a folding line111and the main body10is made of a foldable material.

Therefore, even though the upper surface11is dented, the packaging box may minimize infiltration of contaminants into the inner space14from the outside. As an example, when foods such as fruits are stored in the inner space14, the packaging box allows the user to use the handle20while preventing penetration of bugs from the outside.

The upper surface11has a foldable part112and connection part113. As shown inFIG. 5, when a plurality of the upper surfaces11overlap one another to seal the upper part of the inner space14. In detail, the upper surface11includes a pair of foldable parts112and a pair of connection parts113.

In this instance, the foldable parts112may be arranged on the connection parts113by intersection, and each of the foldable parts112has folding lines111. The folding lines111can maintain a fixed form even though the upper surface111is dented inwardly so as to prevent the contents stored in the inner space14from getting damaged by the upper surface11crushed unnecessarily inwardly.

One of the foldable parts112may have a part of the folding line111, and in this instance, the folding line111disposed on the foldable part112may be varied depending on the general shape of the folding line111.

As an example, if the folding line111is a hyperbolic curve, the folding line111formed on one foldable part112may be a curved line. If the folding line111is in an X-shaped form or in a symmetrically trapezoidal form, the folding line111formed on the foldable part112may be a straight line or a straight line after being bent.

The folding line111may be a hyperbolic curve and nave a convex form at the middle part of the upper surface11. Therefore, when the user presses the upper surface11, the foldable part112may be naturally folded. Of course, the folding line111may not be the hyperbolic curve but be formed in a diagonal line on the upper surface11. That is, the folding line111may have any form if it can make the upper surface11to be dented uniformly.

As an example, the folding line111may be formed in a bilaterally symmetric form to be collected from the outer part to the central part of the upper surface11. Besides the hyperbolic form or the X-shaped form, the folding line111may have one of various forms, such as a symmetrically trapezoidal form.

The connection part113and the foldable part112are in surface contact with each other and may be adhered to each other by glue. Alternatively, the connection part113and the foldable part112may be disposed to simply get in surface contact with each other without using glue so that the foldable part112slides along the side of the connection part113while being folded along the folding line111.

The connection part113may not have the folding line111. Of course, the connection part113may have the folding line111formed at the position corresponding to the area where the folding line is formed. However, the folding direction of the connection part113may be different from the folding direction of the foldable part112, and the folding line111which may be formed on the connection part113may have a form different from the folding line111formed on the foldable part112.

Of course, the upper surface11may have only the foldable part112, but in this instance, in order to tightly seal the upper surface11, the foldable parts112are arranged to be overlapped with one another. However, the packaging box according to the embodiment of the present invention can sufficiently maintain sealing force of the upper surface11when the foldable part112is folded due to the connection part113.

If the main body10is formed in a cuboidal shape, four side surfaces12may be disposed on the main body10. Referring toFIG. 5, four side surfaces12are connected with one another in one direction to form four sides, and junction parts131for connecting one side12to another neighboring side12may be disposed at an end.

The junction parts131may have an adhesive, and adhesive surfaces of the junction parts131are adhered onto the side surface12having the junction part131and the neighboring side surface12so that the four side surfaces12may form the periphery of the main body10. Alternatively, the junction parts131are arranged to overlap the side surface12, and may be attached to the side surface12by various fixing means, such as a stapler.

At least three side surfaces12are disposed to form the inner space14, and the junction parts131may be disposed at one side. One junction part131may be disposed at one side or two junction parts131may be disposed at both sides.

As shown inFIG. 5, the side surface12may be formed when a plurality of the surfaces are folded and connected with one another by the junction parts131. Besides the above, the side surface may be formed when a plurality of the surfaces which are formed individually are connected with each other by the junction parts131. That is, in this embodiment, the formation structure of the side surface12is not restricted.

The side surface12may be a flat surface or a curved surface, and it may be determined in various ways according to shapes of the main body10. The side surface12has the form to surround the inner space14while connecting the upper surface11and the lower surface13.

The side surface12may be made of a flexible material because the cross-section area of the upper surface11may be reduced when the upper surface11is dented inwardly. That is, if the upper surface11is dented inwardly, because the cross-section area of the upper surface11is reduced but the cross-section area of the lower surface13is maintained uniformly, the side surface12may be bent inwardly from the bottom to the top.

The lower surface13is on the opposite side of the upper surface11and seals the inner space14together with the upper surface11and the side surface12. As shown inFIG. 5, the lower surface13may have four wing parts131, and each of the wing parts131may be formed to extend to each side surface12.

In this instance, the wing parts131are disposed to be folded inwardly from the side surfaces12. Because the structure and method of forming the lower surface13while being folded are similar to those of widely known boxes, detailed description thereof will be omitted.

The lower surface13may be formed by assembly of the wing parts131or may be formed in a flat surface. Namely, the lower surface13may be formed in a flat surface and may be connected to the side surface12by various methods, such as adhesion or assembly.

As described above, because the inner space14is formed by the upper surface11, the side surfaces12and the lower surface13and the upper surface11is dented inwardly in order to allow the user to easily grasp the handle20formed on the upper surface11, the packaging box according to the embodiment of the present invention can remarkably improve user convenience.

The handle20is disposed on the upper surface11of the main body10. The handle20may be disposed to get in close contact with the upper surface11of the main body10and the main body10may have a band form to surround the main body10. In this instance, a plurality of the handles20are disposed to intersect each other on the upper surface11. The handle20may surround the main body10such that there is little or no gap between the handle20and the upper surface11. In this instance, the user may feel inconvenient because forcibly opening a gap between the upper surface11and the handle20and putting his or her finger into the gap in order to grasp the handle20, but the packaging box according to the embodiment of the present invention can solve the above problem because the upper surface11is dented.

The handle20may have ring shape which surrounds the lower surface13, two of the side surfaces12and the upper surface11or a curved line form disposed to surround the surfaces except the lower surface13or except the lower surface13and the side surfaces12. The handle20may adopt one of various forms and may be disposed to get in close contact with the upper surface11.

The handle20is disposed to surround the lower surface13and to be located on the upper surface11. In case that there are four side surfaces12, the handle20is disposed to surround all of the side surfaces12to support the load of the contents stored in the inner space14of the packaging box1.

As described above, even though the handle20is disposed to get in close contact with the upper surface11, the user can grasp the handle20easily because the upper surface11is disposed to be dented inwardly, and the packaging box can prevent deterioration in merchantability of the contents because the upper surface11is dented while maintaining sealability of the inner space14.
