Description

Detailed Description of the Invention

[0001]

[Field of Industrial Application] When a user purchases a packaged product and opens the hermetically sealed package using various tools such as scissors, knives, and knives, the user is not limited to this. From the viewpoint of the storability of contents and the prevention of mischief, it is necessary to have a tight sealing property, but it is desired that the contents can be easily opened when used. Among many packages, paper containers are widely used for foods and confectioneries, and the present invention is particularly used as an easily openable container for a seal end carton.

[0002]

2. Description of the Related Art The progress of packaging technology is remarkable, and optimum materials and packaging forms are designed according to the type of contents, distribution conditions, sales form and the like. The paper container called the sealed end carton, which is the object of the present invention, is used as the outer packaging of the double packaging, and the inner packaging is usually a soft packaging bag. The function of the paper container is to protect the contents from shocks,
Further, because of the box shape, it can be easily stored in a cardboard box at the time of distribution and storage, and the display effect at the store is also good. In addition, because it has excellent printability, it has a good sales promotion effect for the container itself, combined with a clean design. Many types of paper containers have been used in the past in terms of openability. For example, there are sleeves and sack types that have been used for a long time in body, lid type, caramel, etc., but the simplest type method called the seal end carton, which is the subject of the present invention, uses less material ( It is an efficient type of paper usage), and it is also suitable for automatic packaging. 5 (A) (B)
Is a type of container called "sealed end carton with zipper" that is often found in conventional products. To open a container of the shape (A), a zipper Z for opening is provided on the outer lid of the container top. In order to open the top cover by pinching the "opening" of the zipper with a finger at one end P of the zipper, and then tearing and removing the zipper part, the container of the shape of (B) is opened. To open the container, a zipper Z is provided on the front plate of the container, and both end plates of the zipper Z provided on the front face and end parts of folding lines provided on the rear plate are connected to both side plates connected to each other. A perforation X for separating and connecting the parts is provided, and the opening is provided on the side plate after grasping the zipper end part of the knob part P of the zipper and tearing and removing the zipper of the container front plate. Detached Separate along the perforation X,
The folding ruled line provided on the rear plate enables a lid for resealing. However, in both of the above types, it is difficult to pinch the end of the zipper at the opening P of the zipper. That is, since the part of the opening P is small, it is difficult to open the finger, and it is difficult to open the finger. In particular, it is difficult for the elderly person, such as the elderly, who cannot use the finger freely. Looking further at this cause, what is usually provided as a zipper for opening is that the width of the zipper is narrow due to the application of adhesive (mostly hot melt type) for sealing the seal end carton. It is normal. The paper container has elasticity and a flat portion can be depressed by pushing with a finger, but in the present invention, there is a crease in the portion to be dented, and the crease has increased rigidity, so that it bends even if pressed with a finger. However, it is not preferable from the viewpoint of easy opening, which is a factor of difficulty in picking the zipper.

[0003]

When opening a sealed end carton with a zipper, a consumer up to an infant or an elderly person can easily grasp the opening of the zipper to improve the tearability of the zipper. As a result, a container that can be easily opened is provided.

[0004]

In order to solve the above problems, the shape of the grip portion at the end of the zipper is examined, and the pushing resistance by the fingers of the side plate connected to the grip portion of the zipper is examined. The present invention can be realized by achieving the reduction. The easily openable container of the present invention comprises a side plate, a front plate, a side plate, a rear plate, and a gluing plate, which are sequentially connected through vertical folding lines, and an outer lid plate on the upper and lower ends of the front and rear plates through horizontal folding lines. And the inner lid plate are connected to each other, and at the upper and lower ends of the left and right side plates,
In a container in which inner lid plates are connected through a horizontal folding rule, and the top outer lid plate or front plate is provided with a tearing zipper, the zipper width of the grip opening is different from that of the other portion. It is configured to be wider than the zipper width. Further, in the easily openable container of the present invention, in a state formed in a box shape, the side plate in contact with the knob portion is easily folded inward so that the side plate near the zipper of the knob portion is folded. Alternatively, it is configured such that cutting lines and the like are provided.

The present invention will be described in more detail with reference to the drawings. FIG. 1 is a perspective view of an embodiment of the easy-open container of the present invention, and FIG. 2 is a development view thereof. As shown in FIG. 1 (B), the side plate 1, the rear plate 2, the side plate 3, the front plate 4, and the gluing plate 5 are sequentially connected to each other through a vertical bending line, and the front plate 4, the side plates 1 and 3 are connected. Top and bottom inner lid plates, 6, 10, 8, 12,
In a container in which 9 and 13 are connected to the upper and lower sides of the rear plate 2 with outer lid plates 7 and 11 through lateral folding lines, respectively, when the outer lid plate 7 is provided with an opening zipper, A)
As shown in (B), the width of the portion close to the zipper-shaped grip portion is widened. At the opening P, a finger easily grips the zipper end. The opening zipper is shown in Fig. 5 (A).
As shown in (B), it has a shape in which a plurality of parallel, intermittently cut lines are provided with diagonal creases for preventing lateral tearing, but in the gluing step when finally sealing the carton, the zipper part The zipper width tends to become narrower because the glue is applied to avoid this. In the present invention, the width of only the gripped portion of the zipper is widened, but when designating the application position of the glue, application to the widened portion is avoided. Even if glue is applied to the back surface of the zipper knob,
It is peeling of the surface layer of the paper of the inner lid 9 or the outer lid 7, and does not show a resistance enough to hinder the opening. Further, as shown in FIG. 2C, a folding rule Y and a cutting rule X are provided on the upper portion of the side plate 3. At the time of opening, pressing the R portion with a finger cuts the ruled line X, the R portion is pushed into the inside of the container, and the knob portion of the side plate 7 can be easily grasped. FIG.
As shown in (B), by making the outer end of the zipper grip portion project, it becomes easier to grip the opening. If the protrusion is about 1 mm, it will not hinder the collection and display. Also, FIG. 2 of the side plate
Compared to (C), a ruled line with a shape like (D), or
Cutting lines may be provided.

For the purpose of the pressing rule and the cutting rule provided in the R portion, various kinds such as the depth of the crease in the folding rule, the type of the cutting rule such as perforations, dot joining, and half cut are used for the purpose. However, the present invention is not particularly limited, and is appropriately selected depending on the type of paper material and the thickness of paper.

[0007]

[Function] By widening the width of the grip portion of the zipper, the area for gripping the finger is increased and the trouble of the finger coming off at the moment of gripping is eliminated. Moreover, when the knob of the zipper is picked, the thumb usually hits the side plate.
As described above, the width of the grip portion of the zipper is widened, and the position of the side plate is further recessed inward when gripping the zipper, which makes it easier to grip the zipper and dramatically improves the unsealing property.
