Description

Cool bag {COOLER BAG}

The present invention relates to a cold storage bag for food, and more particularly, to a cold storage bag in which the food receiving part is double sealed by the outer cover and the cold cover, thereby improving the coolness.

Korean Utility Model Publication No. 20-0467958 (hereinafter referred to as 'prior art'. See FIG. 10 below.) has a flexible membrane 160 on the inner surface of the body member 110 having a space in which food is accommodated. Disclosed is a food packaging bag 100 provided with an internal support member 170 made of a Styrofoam material having a cooling function between the body member 110 and the flexible membrane 160 .

In the food packaging bag 100 , an upper cover 120 provided with an insulating material is connected to the body member 110 by a first zipper 140 . When food is put into the bag and the first zipper 140 is locked, the upper cover 120 closes the space in which the food is put, thereby maintaining the freshness of the food.

Such a conventional bag 100 can maintain the freshness of food for a long time because cold air does not leak to the outside by the internal support member 170 and the cooling material. However, in the conventional bag 100, since the upper cover 120 itself serves to directly open and close the space in which the food is accommodated, the space is inevitably opened when the upper cover 120 is opened, and each time the space inside the space is opened. The cold air is inevitably leaking to the outside.

For example, when a user has to take and insert necessary items among them while several fresh foods are stored in the bag, it is cumbersome to unlock and lock the first zipper 140 each time, so the first zipper 140 In many cases, the upper cover 120 is temporarily placed on the body member 110 while it is left open, but there is a problem in that cold air leaks through the gap of the first zipper 140 that is opened.

In addition, in the conventional bag 100, when the gap between the upper cover 120 and the body member 110 is not reliably airtight, there is a problem in that the time for maintaining the freshness of the food is sharply reduced due to a large amount of leakage of cold air.

In addition, the conventional bag 100 opens the lower surface of the body member 110 to install the inner support member 170 , then locks the second zipper 150 to close the opened lower surface with the bottom cover 130 . is composed of a list. However, in this structure, since the second zipper 150 is exposed to the outside of the body member 110, there is a problem in that the second zipper 150 is slightly opened due to external interference between uses. In this case, as the body member 110 and the upper cover 120 are twisted due to a change in the posture of the internal support member 170 (eg, drooping down), the second zipper 150 is opened more and more, thereby There is a risk that confidentiality may be reduced.

The problem to be solved by the present invention is, first, to provide a cooling bag that can provide better cooling performance than in the prior art.

Second, to provide a cold storage bag that can more reliably seal between a body forming a space for accommodating food and an outer cover closing the open upper surface of the body.

Third, it is to provide a cold storage bag capable of preventing leakage of cold air even when the food in the accommodation chamber is frequently taken out and used with the outer cover open.

The cold storage bag of the present invention has an opening on its upper surface, and accommodates the first insulation interior material between the first insulation interior material defining the accommodation portion for accommodating food, the outer surface and a flexible lining material, and the lining is the accommodation portion A body defining an inner surface, a cooling cover rotatably provided with respect to the body to open and close an inlet defined by the lining corresponding to the opening, an outer cover rotatably connected to the body, and the inlet and a first zipper connecting the outer cover and the outer cover of the body on the outer periphery of the .

The cooling cover may include a second heat insulation interior material and a pocket surrounding the second insulation interior material, one surface in contact with the lining of the body and the other surface facing the inner surface of the outer cover.

A seating surface may be formed at an upper end of the first heat insulation interior material, which is inclined downward from an outer side defining the opening to an inner side. A closing surface corresponding to the seating surface may be formed on a bottom surface of the second insulating interior material for opening and closing the opening.

The cooling cover may be provided with a silver foil reflective plate on the other surface.

The cooling bag may further include a second zipper connecting the outer and the lining from the outside of the inlet, and opening and closing the space in which the first insulating interior material is accommodated.

The first zipper may be disposed above the second zipper.

First, the packaging bag of the present invention can provide superior cooling performance compared to the prior art by applying a double closing structure by the cooling cover and the outer cover.

Second, in the state in which the outer cover is closed by the zipper, since the outer cover presses the cold cover, there is an effect of more reliably blocking the leakage of cold air in the accommodation chamber to the outside.

Third, in the case of using the outer cover open because the food in the accommodation room has to be taken out frequently, only the cold storage cover can be opened and closed while the outer cover is temporarily opened, so that the management of cold air in the accommodation portion and the convenience of use are improved. .

1 to 4, and 7, the cooling bag 1 according to an embodiment of the present invention is a first insulating interior material 70, a body 10, a cooling cover 80, an outer cover ( 20), it may include a first zipper (40).

The first heat insulating interior material 70 defines the accommodating part S in which the food is accommodated, and has an opening 70h in the upper surface so that the food can be put into the accommodating part S. The first heat insulation interior material 70 may have a substantially hexahedral shape, and an opening 70h may be formed on an upper surface of the hexahedron.

The first heat insulating interior material 70 is a heat insulating material for cold or heat preservation, and is made of a material having rigidity to maintain a structurally constant shape, preferably a Styrofoam material, but is not necessarily limited thereto. It is preferable that all parts (or the bottom plate and each side wall plate) of the first heat insulation interior material 70 except the opening 70h are integrally formed.

The body 10 has a dual structure of an outer material 11 and a lining 12 , and the first insulating interior material 70 is accommodated between the outer material 11 and the lining 12 . The outer fabric 11 forms the exterior of the body 10 and may be made of a fabric made of a natural or synthetic material. Since the outer fabric 11 is formed in a shape corresponding to the first heat insulating interior material 70 and is in close contact, the material itself may be flexible, but may maintain a substantially constant shape.

Lining 12 is made of a flexible material to define the inner surface of the receiving portion (S). The lining 12 may be made of a softer or more flexible material than the outer lining 11 . The lining 12 has a larger area than that of the inner surface of the accommodating part S to provide sufficient space for the first insulating interior material 70 to be interposed between the lining 12 and the relatively hard outer fabric 11 .

The cooling cover 80 is rotatably provided with respect to the body 10 to open and close the inlet (10h, see Fig. 6) of the body 10. Here, the inlet 10h corresponds to the opening 70h of the first heat insulating interior material 70 , and is defined as a region limited by the lining 12 .

As shown in FIG. 3 , in the cold cover 80 , the first part 80a may be connected to the outer fabric 11 or the lining 12 of the body 10 by a connecting band 30 .

The bag 1 includes an outer cover 20 rotatably connected to the body 10 from the outside of the receiving portion S. The outer cover 20 may be connected to the outer shell 11 or the lining 12 of the body 10 .

The bag 1 includes a first zipper 40 connecting the body 10 and the outer cover 20 . The first zipper 40 may connect the outer cover 11 and the outer cover 20 of the body 10 around the outer periphery of the inlet 10h. The first zipper (40) has a lower tooth portion (41), an upper tooth portion (42), and at least one slider (43) for locking the lower tooth portion (41) and the upper tooth portion (42) in engagement with them. may include

The outer cover 20, like the body 10, has a dual structure of the outer shell 21 and the inner shell 22, and an insulating material (not shown) may be provided therebetween. The cooling material may be formed in a sheet form, and Styrofoam or pulp material is suitable as the material, but is not necessarily limited thereto. The outer skin 21 may be made of the same material as the outer material 11 . The endothelium 22 may form a reflective plate of silver foil.

The cooling cover 80 may include a second heat insulation interior material 81 and a pocket 82 surrounding the second insulation interior material 81 . The second heat-insulating interior material 81 is approximately formed in a plate shape, and may be made of a heat-insulating material like the first heat-insulating interior material 70 , and is preferably a Styrofoam material, but is not necessarily limited thereto.

One surface 82a of the cold cover 80 or pocket 82 may be in contact with the lining 12 of the body 10 , and the other surface 82b may be in contact with the inner skin 22 of the outer cover 20 . A reflective plate of silver foil may be provided on the other surface 82b. Since external light is reflected by the reflective plate, heat transfer to the accommodating part S can be reduced that much.

Meanwhile, as shown in FIGS. 5 and 9 , inclined seating surfaces 73a , 74a , 75a , and 76a may be formed on the upper end of the first insulating interior material 70 . The seating surfaces 73a, 74a, 75a, and 76a may be inclined downward from the outer side 71 defining the opening 70h toward the inner side 72 opposite thereto. The seating surfaces (73a, 74a, 75a, 76a) are all sides (ie, a pair of horizontal walls (73, 74) and the upper surfaces of the pair of vertical walls 75 and 76)). The pair of transverse walls 73 and 74 and the pair of vertical walls 75 and 76 may extend upwardly from the floor 77 .

Referring to FIG. 5 , the second insulating interior material 81 has an inclined closing surface 81a corresponding to the seating surfaces 73a, 74a, 75a, and 76a on the bottom surface for opening and closing the inlet 10h or the opening 70h. can be The convex portion formed by the closing surface 81a is inserted into the concave portion surrounded by the seating surfaces 73a, 74a, 75a, 76a, so that the seating surfaces 73a, 74a, 75a, 76a and the closing surface 81a are surfaces Because they face to face, the space between the body 10 and the cold cover 80 can be effectively airtight. The closing surface 81a may have a shape substantially corresponding to the seating surfaces 73a, 74a, 75a, and 76a, that is, a rectangular band shape.

In addition, the upper end of the first insulating interior material 70 may protrude further upward than the upper end of the outer fabric 11 . Preferably, the upper end of the first insulating interior material 70 may be disposed higher than the lower teeth 41 of the first zipper 40 . That is, as shown in FIG. 5 , the upper end of the first thermal insulation interior material 70 may be disposed higher than the lower tooth 41 by a predetermined height Δh.

In a state in which the first zipper 40 is locked, the cold cover 80 is pressed on the seating surfaces 73a, 74a, 75a, 76a, and the upper end of the first heat insulation interior material 70 is higher than the lower teeth 41 Since it protrudes to a height, the cold cover 80 may be more tightly pressed against the seating surfaces 73a, 74a, 75a, and 76a.

Further, in the closed state of the cold cover 80, the upper surface (ie, the other surface 82) may be located higher than the upper end of the first insulating interior material 70, in this case, the first zipper 40 is locked, the cold cover 80 may be more tightly pressed against the seating surfaces 73a, 74a, 75a, and 76a.

Meanwhile, referring to FIGS. 6 to 8 , the bag 1 may further include a second zipper 50 connecting the outer fabric 11 and the lining 12 from the outside of the inlet 10h. The space in which the first heat insulating interior material 70 is accommodated is opened and closed by the second zipper 50 . That is, the assembler unlocks the second zipper 50 to open the outer fabric 11 and the lining 12, inserts the first insulating interior material 70 therebetween, and then locks the second zipper 50 again to 1 It is possible to complete the assembly of the insulation interior material (70).

Referring to FIG. 6 , the second zipper 50 may extend in a section SE2 other than the first section SE1 of the body 10 to which the connecting strip 30 is connected. Preferably, the connecting strip 30 is connected to a portion of the section corresponding to the rear side of the rectangular mouth 10h in the outer fabric 11 or the lining 12, and both sides of the portion in the section corresponding to the rear side Sections corresponding to the left, right, and front sides of the rectangular inlet 10h may be connected to the second zipper 50 . The second zipper 50 is located inside the area surrounded by the first zipper 40 when viewed from above.

When viewed from the side, the first zipper 40 may be disposed above the second zipper 50 . Since the second zipper 50 is located below the first zipper 40, it is not exposed to the outside, so that the appearance is improved.

Preferably, the second zipper 50 is located outside the first heat insulation interior material 70 , and is located below the upper end of the first insulation interior material 70 . This structure prevents the second zipper 50 from being opened by not interfering with the second zipper 50 in the process of food being put into the accommodating part S or withdrawn from the accommodating part S.

Meanwhile, although not shown, a separate pocket enclosing the first insulating interior material 70 may be provided according to an embodiment. In this case, after wrapping the first insulation interior material 70 with the pocket (or after inserting the first insulation interior material 70 into the pocket), it is passed through the inlet 10h of the body 10 to the receiving part (S) can be inserted into In this case, the body 10 may have a double structure of the outer fabric 11 and the lining 12 as in the above-described embodiment, but alternatively, only the outer fabric 11 from which the lining 12 is removed may be used. .
