Description

Bag for packing groceries

The present invention relates to a food packaging container, and more particularly to a food packaging container for packaging food, such as fruits and vegetables.

In general, food packaging containers for packaging food such as fruits and vegetables are formed of transparent or translucent vinyl so that the contents can be seen from the outside.

More specifically, the conventional food packaging container forms the front and rear members from vinyl, the joints are formed along the edges of the front and rear members to form a packaging container, and an open surface is formed on top. The said junction part is sealed using normal heat welding etc.

However, the conventional food packaging container is excellent in elasticity but poor breathability because the entire packaging container is formed of vinyl. Therefore, when packaging and storing foods such as fruits or vegetables, the freshness of the contents cannot be maintained, and there is a problem that the food may be damaged.

In addition, the joining portion is formed in a single seal along the joining portions of the front and rear members, so that the joining strength of the joining portion is weak. Therefore, there is a problem that cannot safely support the contents of the food packaging container.

In addition, since the cross sections of both side surfaces and the bottom surface of the food packaging container are constant, the surface area cannot be changed. Therefore, there is a limit that cannot increase the internal capacity of the food packaging container.

The present invention has been made to solve the above problems, to provide a food packaging container capable of imparting breathability to maintain food freshness, such as fruits and vegetables.

Another object of the present invention is to provide a food packaging container capable of increasing the bonding strength of the packaging container junction.

Another object of the present invention is to provide a food packaging container which can increase the internal capacity of the packaging container.

The objects of the present invention are not limited to the above-mentioned objects, and other objects that are not mentioned will be clearly understood by those skilled in the art from the following description.

Food packaging container according to an embodiment of the present invention for achieving the above object, in a packaging container for packaging food, the first member formed of a synthetic resin film, and the second member formed in a network shape A joining portion is formed along edges of the first and second members to form the packaging container, and an upper open surface is formed.

Specific details of other embodiments are included in the detailed description and the drawings.

According to the food packaging container of the present invention as described above has one or more of the following effects.

First, the packaging container is composed of a synthetic film and a mesh to impart breathability, so that the contents of the packaging container, such as fruits or vegetables, can be packaged and stored in a state of maintaining food freshness well.

Second, by joining the junction of the packaging container with multiple sealing to increase the bonding strength of the junction portion, it is possible to safely support the contents of the packaging container.

Third, the inner capacity of the packaging container can be increased by forming both sides or the bottom surface of the packaging container into an expanded cross section to expand the surface area.

The effects of the present invention are not limited to the above-mentioned effects, and other effects not mentioned will be clearly understood by those skilled in the art from the description of the claims.

Advantages and features of the present invention and methods for achieving them will be apparent with reference to the embodiments described below in detail with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but can be implemented in various different forms, and only the embodiments make the disclosure of the present invention complete, and the general knowledge in the art to which the present invention belongs. It is provided to fully inform the person having the scope of the invention, which is defined only by the scope of the claims. Like reference numerals refer to like elements throughout.

Hereinafter, with reference to the accompanying drawings will be described in detail a food packaging container according to an embodiment of the present invention. For reference, in the following description of the present invention, if it is determined that a detailed description of related known functions or configurations may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

1 is a perspective view of a food packaging container according to an embodiment of the present invention, Figure 2 is a cross-sectional view taken along the line II-II 'of FIG.

As shown in Figure 1 and 2, the food packaging container according to an embodiment of the present invention includes a first member 10, the second member 20 and the like.

The first member 10 is formed of a synthetic resin film. For example, the first member 10 is elastic and is formed of transparent or translucent vinyl so that the contents of the packaging container can be seen from the outside. The first member 10 has a predetermined area of a rectangle to form one side, preferably the front side, of the packaging container. Various printing contents related to the product may be printed on the first member 10. The first member 10 includes a lower folder portion 11 that is folded upward and joined to the lower end of the second member 20 after the lower end is extended.

The second member 20 is formed in a mesh shape in which a plurality of vent holes are formed on a surface thereof. The second member 20 is preferably formed of a breathable nonwoven fabric, a synthetic mesh, or the like. The second member 20 has a form of a net that can satisfactorily satisfy breathability and firmness. More specifically, when the ventilation hole is formed in the form of a network that is too large or too large, the second member 20 has good breathability but the strength that can withstand the load of the contents is weakened. On the contrary, in the case of a net in which the air vents are formed too small or too small, the second member 20 has a strong strength but poor breathability. Therefore, it is preferable that the second member 20 appropriately forms the size and the number of the ventilation holes so as to satisfy both the breathability and the firmness. The second member 20 has a predetermined area of a square corresponding to the first member 10 to form the other side of the packaging container, preferably the rear surface.

5 is an exemplary view in which a catching hole is formed in a food packaging container of the present invention.

As shown in FIG. 5, the food packaging container of the present invention may have a third member 30 bonded to an upper end of the second member 20. Here, the upper joint 21d is formed to join the upper end of the second member 20 and the lower end of the third member 30, and the upper joint 21d applies the second sealing method, and double sealing It is preferable to join.

The third member 30 is preferably formed of the same material as that of the first member 10, that is, a synthetic resin film. At least one catching hole 31 is formed in the third member 30 to be fitted to the packaging container latch provided in the automatic packaging apparatus (not shown).

Food packaging container according to an embodiment of the present invention is configured as described above is a packaging container for packaging food, such as fruit or vegetables, one side of the packaging container is formed of a synthetic resin film, the other surface is a plurality of vents It is excellent in firmness and air permeability by consisting of the mesh formed. Therefore, the contents of the packaging container, for example, can be packaged and stored in a state that maintains the food freshness such as fruits and vegetables well.

Moreover, the joining part 21 of the 1st, 2nd and 3rd member 10, 20, 30 which comprises a packaging container is joined by multiple sealing, and the joining strength of the joining part is excellent. Therefore, the contents of the packaging container can be safely supported.

In addition, by providing the zipper 22 to seal the upper open surface 12 of the packaging container, the packaging container can be easily sealed.

In addition, automatic packing is possible by having the catching hole 31 formed in the packaging container fit into the packaging container latch of the automatic packaging device.
