Description

Easy to open packaging bag {paper bag open system}

The present invention relates to a packaging bag, more specifically, a disposable bag such as capping, sauce, and the like used as a container for packaging such as confectionery, and can be easily opened by anyone. It is easy to open the bag, so it is easy to take out the contents, and can be eaten while capping, sauce, etc. packed in the packaging, easy to separate and easy to recycle, environmentally friendly. Although many methods of opening bags have been proposed, a method of opening only one side of a packaging bag in a convenient way has been solved.

To this end, the present invention, by the bonding process in such a way that the end portion of the bag is extended to the opening position of the opening handle that extends one side of the packaging bag is bonded to the force received by the contents as there is no risk of natural damage, opening the bag Only one thing would be convenient. The opening of the bag can be easily opened wide, so that the contents can be easily taken out, and the bag itself can be used as the contents container. The contents of the liquid form can be used neatly by unfolding the bag itself.

In general, the opening of the bag containing the contents is used to tear one side. Some are forced to tear, causing the contents to spill out. Usually, the contents are transferred to a bowl and poured into paper. The end of the bag's junction is often bent to tear it off. Disposable packaging contents, such as cappants and mayonnaise, are generally impossible to open only one side of the packaging bag, so it is common to squeeze and eat paper. This is a problem that is difficult to recycle because of a large number of separate collection. Even in the case of packaging such as disposable shampoo and rinse, it is possible to open the contents of two people neatly if it can be opened wide in general. There is a need for a bag that can be easily opened on one side, a bag that can be used as a bowl, and a bag that can use the contents neatly.

In order to solve the problems described above, the present invention is capable of opening only one side of the packaging bag by double-bonding the finishing adhesive part of the packaging bag, but the force of the contents is the same as before, and there is no fear of natural damage. It is an object of the present invention to make it easy to take out the contents, to use itself as a bowl, to make the contents clean, and to be environmentally friendly and to facilitate recycling.

In order to achieve the above object, the present invention, by extending the finishing adhesive portion of the packaging bag and re-bonded in a manner that is connected to the start position of the opening handle extending one side of the packaging bag, the force received by the contents is the same as before There is no concern, and only the opening of the bag is made conveniently, it is possible to open only one side without effort, it is possible to use the contents without leaving. Only one side of the bag can be opened wide, it is easy to use itself as a bowl, it is easy to separate collection, and the contents can be used without leaving the environment-friendly features.

Hereinafter will be described in detail (by the accompanying drawings).

By re-bonding by connecting the end of the packaging bag to the opening position of the opening handle that extends one side of the packaging bag, the strength of the contents is the same as before, and there is no risk of natural damage. Thus, it is possible to open only one side without effort, and to use the contents without leaving. Bonding of the opening handle and the connecting method is a strong bonding because the force acts in the longitudinal direction when the bag is pressed from the external force, and when the pull handle is pulled, it is easily opened because the force acts vertically on the joint. In the storage state, the opening handle is strong with the force received from the outside because it is together with the end adhesive portion 204 of the packaging bag.

In FIG. 1, reference numeral 101 is a front surface of a packaging bag for packing a cake or the like. 102 is an end adhesive part of which both sides of the packaging bag are joined. 103 is the back side of the bag. In the case of 104, the packaging bag is opened using a wrinkle in the center of the back side of the general bag. 105 is a side structure of the packaging bag. 106 is the end bonding portion seen from the side of the packaging bag. 107 is bent to facilitate opening at the end adhesive portion of the packaging bag. 108 is a state which is opened using the bending treatment of the packaging bag. 109 is in the form of packaging bags used as disposable containers such as capping, sauces and the like. 110 is the side of a disposable packaging bag. 111 is a disposable packaging bag for shampoo, rinse, and the like.

In FIG. 2, 201 is a front side of a packaging bag that can be opened only on one side. 202 is an opening strip provided at the edge of the packaging bag so that only one side can be opened with the same width. 203 is a side of a packaging bag that can be opened only one side. 204 is an end adhesive portion of the packaging bag. The end adhesive portion is extended so that the other side of the packaging bag is bonded by attaching the extended opening handle beginning. 205 is a structure in which one side of the packaging bag is extended by an opening handle of the packaging bag introduced to facilitate opening of the packaging bag. The opening handle is wide enough to be grasped by hand. By opening the end of the opening handle is made to bend to determine the initial incision width of the bent place can be adjusted to the desired opening size. 206 is an adhesive portion of the packaging bag in which the packaging bag adhered to the end adhesive portion 204 is extended to be bonded to the position before opening the opening handle. 207 is a packaging bag having an opening strip at regular intervals. The opening strip can be used to open the packaging bag in the desired width. 208 is a state in which one side of the packaging bag is opened widely along the opening strip provided at the edge.

When applied to a cookie bag, children, the elderly and others can easily open only one side of the packaging bag to the desired width, it was solved that it is inconvenient to take out the contents due to the narrow entrance even after opening. It also solved the problem of spilling the contents when the bag was opened by mistake. In the case of disposable packaging such as sauces, capps, etc., the contents must be eaten, only one side can be opened wide, so that it can be eaten on its own. This does not squeeze the contents, such as paper, the cleaning time of the tray is shortened, recycling, separate collection is also convenient. In the case of disposable packaging such as shampoo and rinse, it is possible to use the contents neatly. There is no inconvenience to open retort packaging and refill packaging using scissors. In the case of sauces, jams, and syrups that scoop up or eat the contents, the container can be replaced with a plastic bag instead of a bag, with a simple and economical one-sided bag. This can be applied to all envelopes of paper material that both sides are bonded to form a packaging bag, so that the envelope is easy to open. Packaging bags that can only be opened on one side are convenient for retort products such as curry and jjajang, so that rice can be eaten in the packaging bags without the need for a separate bowl outdoors.

The present invention as described above is not limited to the preferred embodiment as described above, it is common in the art to which the present invention pertains without departing from the spirit of the invention as claimed in the claims of the present invention. Those skilled in the art can make various modifications, as well as such modifications will be within the scope of the claims described as key elements of the present invention.

As described above, in the present invention, the bonding force is applied in such a manner that the end adhesive portion of the packaging bag is extended so that one side of the packaging bag is connected to the opening portion of the opening handle, which is extended, so that the contents receive the same force as before. It is possible to conveniently open only the packaging bag, it is possible to open only one side without effort, the contents can be easily taken out, it is possible to use without leaving. It is easy to open the bag widely, it can be used without any contents, it is environmentally friendly, and it can be used as a bowl, and it is easy to separate and easy to recycle, so its utility is large.
