THERMAL BAG

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.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a thermal bag, and more particularly to a thermal bag with a convenient opening.

2. Description of the Prior Art

A thermal bag is widely used in daily life, especially in the field of takeout and medicine. Compared with an ordinary bag, the inner layer of the thermal bag is made of aluminum foil. Through PE cotton having thermal insulation function, the bag has the effect of short-term heat preservation, so as to hold various foods and maintain the temperature and freshness of the foods. The medical personnel may use the thermal bag for carrying some medicines that need to be kept in a constant temperature environment when going out.

In general, the thermal bag is made of Oxford fabric or nylon fabric, and the opening is relatively soft, which causes the shape of the opening to be irregular after the zipper is unzipped. It is inconvenient to take and place articles.

SUMMARY OF THE INVENTION

The primary object of the present invention is to provide a thermal bag with a convenient opening. The opening has a shaping ability, thereby forming a stable shape and facilitating placement of articles.

A thermal bag comprises 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.

Preferably, 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.

Preferably, top shaping boards are interlaid between the outer layer fabric and the inner layer fabric of the opening portion for supporting the fabrics of the opening portion.

Preferably, the top shaping boards are foam boards.

Preferably, a side shaping board is interlaid between an outer layer fabric and an inner layer fabric around the accommodating portion for supporting the fabrics of the accommodating portion.

Preferably, the side shaping board is a foam board.

Preferably, a pair of handles is mounted on two sides of an outer wall of the accommodating portion.

With the above structure, when the zipper is zipped, the two support bars support the fabrics of the opening portion, so that the bag is formed with a relatively flat top surface. 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.

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

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

As shown inFIG. 1, a thermal bag comprises a thermal insulation main body1and a zipper2. The thermal bag main body1is in the shape of a bag which is common in daily life, and includes an accommodating portion11and an opening portion12. The accommodating portion11is connected to the opening portion12, and the two cooperate with each other to form the thermal bag having an internal closed space.

As shown inFIG. 2, a side shaping board111is interlaid between an outer layer fabric and an inner layer fabric around the accommodating portion11, so that the accommodating portion11has a regular cylindrical shape, and the internal space is more suitable for placing articles, not in a state of chaos. A pair of handles3is mounted on two sides of the outer wall of the accommodating portion11for moving and carrying the thermal bag.

As shown inFIG. 3, the opening portion12is formed with an opening121. The opening121is mounted with the zipper2for opening and closing the internal space of the thermal bag.

The improvement of the present invention is that two support bars122are interlaid between an outer layer fabric and an inner layer fabric of the opening portion12at two sides of the zipper2, respectively. The two support bars122extend in the direction of the opening121.

The two support bars122extend to a position beyond the side wall of the accommodating portion11and are bent toward each other, directed to the end of the zipper2. The support bars122support the fabrics at the edge of the opening121, such that the opening121has a certain shape.

Top shaping boards123for supporting the fabrics of the opening portion12are interlaid between the outer layer fabric and the inner layer fabric of the opening portion12below the support bars122, respectively. The top shaping boards123can support most of the fabrics of the opening portion12.

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

With the above structure, when the zipper2is zipped, the two support bars122support the fabrics of the opening portion12, so that the bag is formed with a relatively flat top surface. When the zipper2is unzipped, the two support bars122cooperate with each other to brace the fabrics of the opening portion12, so that the opening121is formed in a stable shape, does not collapse and is more convenient for taking and placing articles.

In addition, the top shaping boards123increase the ability of the opening portion12to be shaped while increasing the thermal insulation function.
