Definitions
- the present invention relates to a bag structure and particularly to a bag to gather and hold goods together and facilitate carrying or hanging.
- Bags are widely used in people's daily life. Cheap, sturdy, easy to carry and clean are common desirable features of a bag for buyers or sellers. These days many buyers also want the bag eco-friendly without creating environmental pollution after use, small size, easy to store and manage.
- plastic bags are banned in many shopping centers and food stores, but these places provide bags with a flat opening as the alternatives. While such bags can gather goods together, they do not have handles for holding, hence are difficult to carry. They usually have to be carried by users in a holding or grasping manner.
- FIGS. 1 and 2 Please refer to FIGS. 1 and 2 for a conventional bag 1a with a flat opening 2a. It can be fabricated easily at a lower cost.
- the opening 2a When in use, the opening 2a generally is folded and carried by a user with a hand. When the goods held in the bag 1a is heavier, one corner of the folded opening 2a has to be folded again to form a folded angle 21a to increase the support strength. But the bag 1a still has to be carried by holding or grasping during walking or taking vehicles and becomes a troublesome burden, especially when the road condition is poor or a crowded condition happened in the vehicles, or a lot of goods are held in the bag. The bag could be easily slipped or dropped from user's hands and cause difficulty in carrying.
- the bag 1b has a perforated slot near the opening 2b to form a handle 4b.
- the conventional flat opening bag 1b is usually fabricated from plastics or paper.

- the weight of goods does not concentrate on the two slots 532 and 542 so that the handles 531 and 541 are less likely to be deformed or broken.
Abstract
A bag structure includes a main body (5) which has an opening (51) at the upper end, two opposing surfaces (53, 54), two folded portions (530, 540) formed on the surfaces (53, 54) close to the opening (51), and handles (531, 541) below the folded portions (530, 540) to facilitate hand grasping and hanging. When in use, the folded portions (530, 540) are folded and overlapped to form a folded edge (55); the handles (531, 541) are lifted to wrap the folded edge (55) to increase the thickness above the handles (531, 541) so that support strength increases and grasping comfort improves. The bag thus formed can be fabricated easier at a lower cost in mass production, and can be neatly folded and stored.
Description
- The present invention relates to a bag structure and particularly to a bag to gather and hold goods together and facilitate carrying or hanging.
- Bags are widely used in people's daily life. Cheap, sturdy, easy to carry and clean are common desirable features of a bag for buyers or sellers. These days many buyers also want the bag eco-friendly without creating environmental pollution after use, small size, easy to store and manage. Nowadays plastic bags are banned in many shopping centers and food stores, but these places provide bags with a flat opening as the alternatives. While such bags can gather goods together, they do not have handles for holding, hence are difficult to carry. They usually have to be carried by users in a holding or grasping manner.
- Please refer to
FIGS. 1 and2 for a conventional bag 1a with aflat opening 2a. It can be fabricated easily at a lower cost. When in use, the opening 2a generally is folded and carried by a user with a hand. When the goods held in the bag 1a is heavier, one corner of the foldedopening 2a has to be folded again to form a foldedangle 21a to increase the support strength. But the bag 1a still has to be carried by holding or grasping during walking or taking vehicles and becomes a troublesome burden, especially when the road condition is poor or a crowded condition happened in the vehicles, or a lot of goods are held in the bag. The bag could be easily slipped or dropped from user's hands and cause difficulty in carrying. - To remedy the problem of difficult carrying, another type of flat opening bag 1b was developed and produced as shown in
FIG. 3 . The bag 1b has a perforated slot near the opening 2b to form ahandle 4b. The conventional flat opening bag 1b is usually fabricated from plastics or paper. For the plastic bag, as the plastics are flexible, the plastic portion above thehandle 4b tends to be stretched thinner after the bag 1b is loaded with goods. Hence the bag 1b is deformed and difficult to manage for storing, and the structure of thehandle 4b is also changed that creates concerns for reuse. Moreover, as the flat opening bag 1b is made of paper, thehandle 4b is the perforated slot which damages the structural support strength around the opening 2b and easily causes fracture at thehandle 4b and results in a greater problem in use. -
FIG. 4 shows still another type of a conventional bag 1c withtwisted ropes 3c fastened to the opening 2c. Fabricating such a bag requires a tedious process and incurs a higher cost. Moreover, the loading of the bag 1c concentrates on the fastening portion of thetwisted ropes 3c at the opening 2c which is easily fractured. Also thetwisted ropes 3c of the bag 1c cannot be perfectly fitted to the opening 2c while folded, hence scars could be occurred while transportation or storage, and the appearance is suffered. -
FIG. 5 shows yet another type of a conventional flat opening bag 1d which has ahandle 4d andpatches 41 d bonded to thehandle 4d to increase the strength. As it requires extra production process to add thepatch 41d, the cost is higher. In the event that thepatch 41d is made from a non-degradable material, environmental pollution occurs. - The primary object of the present invention is to overcome the shortcomings of the conventional flat opening bags that are not sturdy and inconvenient to use. The present invention provides an improved bag that can be produced at a lower cost and easy to hold or hang to meet actual use requirements.
- To achieve the foregoing object, the present invention provides a bag structure which includes a main body with two surfaces opposing each other, the two surfaces have folded portions close to an opening and a handle beneath the folded portions. The handle is formed by punching and cutting to become split line in advance. The handle can be formed in a circular, square, arched or other geometrical shape to facilitate insertion of user's fingers for carrying or hanging on a holding hook on a transportation vehicle or article, or also can be formed in a special design as desired.
- When the bag of the invention is in use for holding goods, the folded portions are folded to a plurality of folds towards the surface until reaching an upper side of the two handles to form a folded edge to close the upper end of the main body, then the lower edges of the two handles are lifted upwards to be overlapped and bent towards the surface. The two lifted handles are formed respectively a slot on the surface corresponding to each other. The folded edge is held by the two lifted handles to prevent it from loosing and also increases the thicknesses of the upper edges of the two slots. Thus the invention does not damage the structure of the bag and has the folded edge formed by the folded portions to increase the thicknesses above the handles to enhance support strength above the handles and improve user's grasping comfort. When the bag is loaded with goods, the portions above the handles are less likely to be deformed or fractured.
- Moreover, protective patches may be added to attach the inner sides of the surfaces at the borders of the two slots to further increase the support strength. The protective patch is a frame and can enhance the support strength of the handle and folded edge at the opening to make the bag sturdier.
- In short, the bag according to the invention provides many benefits, notably:
- 1. The handles are formed by punching during production, and can be made faster at a lower cost.
- 2. The bag of the invention can be carried by grasping when holding goods, thus provides the convenience of the bag.
- 3. The bag of the invention can be hung on a holding hook to facilitate carrying while driving or riding a transportation vehicle.
- 4. The handles of the invention are folded and overlapped to increase the support strength of the bag opening without creating extra fabrication process, thus the bag can be made at a lower cost like a conventional flat opening bag, and also is easier to store and transport.
- The foregoing, as well as additional objects, features and advantages of the invention will be more readily apparent from the following detailed description, which proceeds with reference to the accompanying drawings.
