THERMAL BAG

Abstract

A thermal bag includes a thermal bag main body and a zipper. The thermal bag main body includes an accommodating portion and an opening portion. The accommodating portion is connected to the opening portion to form the thermal bag. The opening portion is formed with an opening. The opening is mounted with the zipper. Two support bars are interlaid between an outer layer fabric and an inner layer fabric of the opening portion at two sides of the zipper, respectively. The two support bars extend in the direction of the opening. When the zipper is unzipped, the two support bars cooperate with each other to brace the fabrics of the opening portion, so that the opening is formed in a stable shape, does not collapse and is more convenient for taking and placing articles.

Claims

1. A thermal bag, comprising a thermal bag main body and a zipper, the thermal bag main body including an accommodating portion and an opening portion, the accommodating portion being connected to the opening portion to form the thermal bag, the opening portion being formed with an opening, the opening being mounted with the zipper, characterized in that: two support bars are interlaid between an outer layer fabric and an inner layer fabric of the opening portion at two sides of the zipper respectively, and the two support bars extend in the direction of the opening.

2. The thermal bag as claimed in claim 1, wherein the two support bars extend to a position beyond a side wall of the accommodating portion and are bent toward each other, directed to an end of the zipper.

3. The thermal bag as claimed in claim 1, wherein top shaping boards are interlaid between the outer layer fabric and the inner layer fabric of the opening portion for supporting the outer and inner layer fabrics of the opening portion.

4. The thermal bag as claimed in claim 3, wherein the top shaping boards are foam boards.

5. The thermal bag as claimed in claim 1, wherein a side shaping board is interlaid between an outer layer fabric and an inner layer fabric around the accommodating portion for supporting the outer and inner layer fabrics of the accommodating portion.

7. The thermal bag as claimed in claim 1, wherein a pair of handles is mounted on two sides of an outer wall of the accommodating portion.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0016] FIG. 1 is a perspective view of the present invention;

[0017] FIG. 2 is a schematic view of the present invention in a closed state; and

[0018] FIG. 3 is a schematic view of the present invention in an open state.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings.

[0020] As shown in FIG. 1, a thermal bag comprises a thermal insulation main body 1 and a zipper 2. The thermal bag main body 1 is in the shape of a bag which is common in daily life, and includes an accommodating portion 11 and an opening portion 12. The accommodating portion 11 is connected to the opening portion 12, and the two cooperate with each other to form the thermal bag having an internal closed space.

[0021] As shown in FIG. 2, a side shaping board 111 is interlaid between an outer layer fabric and an inner layer fabric around the accommodating portion 11, so that the accommodating portion 11 has a regular cylindrical shape, and the internal space is more suitable for placing articles, not in a state of chaos. A pair of handles 3 is mounted on two sides of the outer wall of the accommodating portion 11 for moving and carrying the thermal bag.

[0022] As shown in FIG. 3, the opening portion 12 is formed with an opening 121. The opening 121 is mounted with the zipper 2 for opening and closing the internal space of the thermal bag.

[0023] The improvement of the present invention is that two support bars 122 are interlaid between an outer layer fabric and an inner layer fabric of the opening portion 12 at two sides of the zipper 2, respectively. The two support bars 122 extend in the direction of the opening 121.

[0024] The two support bars 122 extend to a position beyond the side wall of the accommodating portion 11 and are bent toward each other, directed to the end of the zipper 2. The support bars 122 support the fabrics at the edge of the opening 121, such that the opening 121 has a certain shape.

[0025] Top shaping boards 123 for supporting the fabrics of the opening portion 12 are interlaid between the outer layer fabric and the inner layer fabric of the opening portion 12 below the support bars 122, respectively. The top shaping boards 123 can support most of the fabrics of the opening portion 12.

[0026] The shaping board may be a foam board which is common in life and is light and practical.

[0027] With the above structure, when the zipper 2 is zipped, the two support bars 122 support the fabrics of the opening portion 12, so that the bag is formed with a relatively flat top surface. When the zipper 2 is unzipped, the two support bars 122 cooperate with each other to brace the fabrics of the opening portion 12, so that the opening 121 is formed in a stable shape, does not collapse and is more convenient for taking and placing articles.

[0028] In addition, the top shaping boards 123 increase the ability of the opening portion 12 to be shaped while increasing the thermal insulation function.

[0029] Although particular embodiments of the present invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the present invention. Accordingly, the present invention is not to be limited except as by the appended claims
