Prior Art

Today, there are carrier bags made of different materials intended for various areas of use. However, currently available carrier bags are manufactured monolithically. There are also version where the handle is joined. However, they fail to deliver the required strength and problems are encountered.

In the production stage of the carrier bags of the state of the art, there are wastes. In addition, the bag volume can not be used efficiently in the existing carrier bags.

In the state of the art, various problems are encountered with these carrier bags. Separation through joining areas, breaking off of the carrying handle, not being ergonomic, failing to provide ease of use, and having the opening of the bag uncovered are among the mentioned problems.

Existing carrier bags do not provide ease of carrying to the user. Since handle strength is low, problems such as separating from joining points or breaking off of the handle while carrying heavy products are encountered. In addition, since the opening of the bag is uncovered, hygiene and privacy of the products inside the bag can not be ensured. Due to these problems, the user suffers economic losses.

Detailed Description of the Invention

In Figure-1 ; a perspective view of the carrier bag with cover (100), the subject-matter of the invention, is illustrated. The invention allows production of a carrier bag with cover

(100) with very little waste to prevent economic losses and labor losses and to produce a high strength carrying bag with cover (100).

In Figure-2; another perspective view of the carrier bag with cover (100), the subject- matter of the invention, is illustrated. There are main walls (104) which allow forming the bags with cover (100) which can be made of various materials. There are side walls (103) that connect with the main walls (104) and form a volume gap surface. There are independent handles (101 ) produced independently of the main walls (104) and connected to the main walls (104) by various methods. A carrying gap (105) is introduced inside the mentioned independent handle (101 ) to provide ease of carrying. A joining area (102) is introduced to join the mentioned main walls (104) and the independent handle

(101 ). A left cover (107) which is connected during or after the joining of the independent handles (101 ) to opening part of the main walls (104) in such a way to cover the opening portion of the carrier bag in order to close the opening of the carrier bag is introduced. The material structure and width and length of the mentioned left cover (107) can be chosen as desired, in accordance with the width of the carrier bag with the cover (100). A right cover (106) which is connected during or after the joining of the independent handles (101 ) to opening part of the main walls (104) in such a way to cover the opening portion of the carrier bag is introduced to close the opening of the carrier bag. The material structure and width and length of the mentioned right cover (106) can be chosen as desired, in accordance with the width of the carrier bag with the cover (100). A closing portion (108) which allows opening and closing of the mentioned right cover (106) and left cover (107) is provided. The closing portion (108) can be selected from Velcro tape, snaps, magnets, zippers and similar products.

The joining area (102) connecting the independent handle (101 ), right cover (106) and left cover (107) to the main walls (104) is formed by joining with ultrasonic welding. Furthermore, in addition to the ultrasonic welding method, the joining process can be performed with chemical adhesive or similar holders. The mentioned joining area (102) can be of a linear form or joining can be achieved through different geometric shapes.

In Figure-3; schematic view of the steps of the production method of the carrying bag (100), the subject-matter of the invention, is illustrated. The method of production of carrier bag (100) which allows connecting the independent handle (101 ), the right cover (106) and the left cover (107) to be connected to the carrier bag (100) are; separation of two side walls (103) with the opening forming unit (A), inserting the pattern portion between the opened two side walls (103) (B), placing the independent handle (101 ) which has been cut out in the desired outer form and in a form fitting on hands at the grip feeding part, the right cover (106) and the left cover (107) between the main wall (104) and the pattern portion and joining with ultrasonic welding or chemical adhesive joining method (C). The right cover (106) and left cover (107) parts can be fed and joined with the independent handle (101 ), and can also be attached after the handle by feeding separately at an additional station. The said production method is carried out quickly with an automation system.
