Description

(4) When purchasing a packaged product and opening the sealed package, the user is not limited to using a variety of tools such as scissors, a kitchen knife, and a knife. From the viewpoint of the storage stability of the 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 frequently used for foods and confectionery, and the present invention is particularly used as an easily-openable container for a sealed end carton.

There has been remarkable progress in packaging technology, and optimal materials and packaging forms are designed depending on the type of product, distribution conditions, and sales form. The paper container called a seal-end carton, which is the object of the present invention, is used as a double-wrapped exterior, and the interior is usually a soft-wrapped bag. The function of the paper container is to protect the contents from impact and to be box-shaped, so that it is easily stored in a cardboard box during distribution and storage, and has a good display effect at stores. In addition, since it is excellent in printability, the sales promotion effect of the container itself is good in combination with the clean design. Many types are conventionally used from the viewpoint of openability of paper containers. For example, there are a sleeve and a sack type which have been used for a long time for body, lid type, caramel and the like, but the simplest type called a seal end carton which is the object of the present invention has a small material use area ( This is a type that is used very often recently because it is also excellent in automatic packaging suitability. FIGS. 5 (A) and 5 (B) show a type of container called "seal-end carton with zipper" which is often seen in conventional products, and the container having the shape shown in FIG. 5 (A) is opened on the outer lid of the container top. A zipper Z is provided. The zipper Z is gripped by a finger at a gripping opening P at one end thereof, and then the zipper portion is torn and removed to open the top cover. For opening the container having the shape shown in FIG. 1, a zipper Z is provided on the front plate of the container, and the end portions of the zipper Z provided on the front surface and the folding plates provided on the rear plate are provided on both side plates connected to each other. A cut perforation X 'is provided by tying each end of the ruled line, and when opening the zipper, the zipper end of the zipper knob P is gripped and the zipper of the container front plate is torn and removed. After the separation provided on the side plate Disconnecting at the perforation X', provided in the rear plate, by the folding ruler line can lid for resealing. However, in both types, it is difficult to pick the zipper end at the zipper picking opening P. That is, since the portion of the knob P is small, it is difficult to put a finger on it, and it may be difficult to open the finger. Looking further at this cause, what is usually provided as a zipper for opening is that the width of the zipper is narrow because of the application of an adhesive (often hot-melt type) for sealing the seal end carton. Normal. Paper containers have elasticity, and flat parts can be depressed when pressed with a finger.However, in the present invention, the part to be depressed has a crease, and the crease has increased rigidity and can be bent even when pressed with a finger. However, it is not preferable from the viewpoint of easy opening, which is a cause of the difficulty in picking the zipper.

In opening a sealed end carton with a zipper, infants and consumers up to the elderly can easily pick up the opening of the zipper, thereby improving the tearability of the zipper, and as a result, a container that can be easily opened. I will provide a.

The present invention for solving the above-mentioned problem, the side plate, the front plate, the side plate, the rear plate and the gluing plate are sequentially connected via the vertical folding rule, and the upper and lower ends of the front and rear plates are connected via the horizontal folding rule. A container in which the outer lid plate and the inner lid plate are connected to each other, and the upper and lower ends of the left and right side plates are connected to the inner lid plate via horizontal folding rules. A zipper is provided, and in the easy-open container in which the zipper width of the opening of the opening zipper is wider than the zipper width of the other portions, the parallel portions in the two rows of the tear zippers are interrupted. A plurality of cut rules are formed with oblique lines in a shape that is provided at an obtuse angle continuously to the cut rules in the facing inward direction. A shape provided at an obtuse angle in the outward direction to be continuous with the cutting rule It is a easy-open container, characterized in that the.

As described above, in the seal end carton with the zipper, the width of the zipper opening is widened, and the concave forming portion for facilitating pushing by the finger into the side plate connected to the opening is folded and creased. With the provision, the opening can be easily performed by an infant, a child, or the elderly, and the opening can be greatly facilitated.

The present invention will be described in more detail with reference to the drawings and the like. FIG. 1 is a perspective view of an embodiment of an easily-openable container according to the present invention, and FIG. 2 is a developed 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 via a vertical bending line, and the front plate 4, the side plates 1, 3 A container having upper and lower inner lid plates, 6, 10, 8, 12, 9, 13 connected to upper and lower rear plate 2 outer lid plates 7, 11 via horizontal bending lines, respectively, 7, when the opening zipper is provided, as shown in FIGS. 2A and 2B, the width of a portion close to the zipper-shaped knob P is increased. A finger makes it easy to pinch the zipper end at the pinch opening P.

Further, in the easy-open container of the present invention, the parallel portions of the two rows of the opening zipper have a shape in which a plurality of intermittent cut rules are provided with oblique rules, and the oblique angles are provided continuously to the cut rules in opposing inward directions. The obliquely extending portion near the knob P has a shape in which a plurality of intermittent cutting rules are provided with oblique rules at an obtuse angle in a direction opposite to each other. By adopting this shape, the oblique cutting rule at the portion of the knob P can be continuously and smoothly torn.

As shown in FIGS. 5A and 5B, the conventional opening zipper has a shape in which two rows of parallel intermittent creases are connected to a plurality of parallel creases for preventing horizontal tearing. In the gluing step when sealing the zipper, the width of the zipper tends to be narrowed in order to apply the glue while avoiding the zipper portion. In the present invention, the width of only the grip portion of the zipper is widened, but application of the paste to the widened portion is avoided in specifying the application position of the glue. Even if glue is applied to the back surface of the grip portion of the zipper, the inner cover 9 or the outer cover 7 is peeled off the surface layer of the paper, and does not exhibit a resistance that would hinder opening. Further, a folding rule Y and a cutting rule X are provided on the upper portion of the side plate 3 as shown in FIG. At the time of opening, by pressing the recessed portion R with a finger, the crease X is cut, the recessed portion R is pushed into the inside of the container, and the knob of the side plate 7 can be easily picked. . As shown in FIG. 2 (B), by making the outer end of the zipper opening P protrude, the operation of the opening of the opening is further facilitated. If the degree of the protrusion is about 1 mm, no problem occurs in stacking or displaying. Further, the side plate may be provided with a crease Y as shown in FIG.

For the purpose of the pressing rule and the cutting rule provided in the portion of R, various types such as a depth of the folding rule, a kind of the cutting rule, for example, perforation, a point connection, and a half cut can be used. The present invention is not particularly limited, and is appropriately selected according to the type of paper material and the thickness of paper.

Thus, by increasing the width of the zipper knob, the area where the finger is picked is increased, and the trouble that the finger comes off at the moment of the pinch is eliminated. In addition, it is common that the thumb hits the side plate when picking the zipper. As described above, the width of the zipper knob opening is widened, and the position of the side plate is further depressed inward to form a concave portion when the pinch is further pinched, so that the zipper can be easily picked and opened. Has improved dramatically.

<Example 1> A zipper is provided at the top of a carton having a front width of 90 mm, a depth of 35 mm, and a height of 170 mm after assembly, and the zipper has a width of 10 mm. Was 30 mm, gradually narrowed to 10 mm at a position 15 mm from the knob, and a side plate in contact with the zipper portion was provided with a recess forming portion of the same type as that of FIG. 2C. The recess forming portion has an inverted trapezoidal shape, the crease Y located at the lower part is 15 mm, the crease Y is 14 mm from the side plate, and the crease X extending from both ends of the crease Y to the upper left and right corners of the side plate. Was provided. When the container is opened and the depression R is lightly pressed with the thumb, the crease X is cut, the depression R is pushed into the carton, and the zipper is easily picked. The container can be opened very easily by a zipper, and can be resealed by the tongue piece n and the receiving port m.

<Example 2> Example in the case of a seal end carton with a zipper having a zipper on the front plate. FIG. 3 shows a case in which a zipper is provided on the front surface of the seal end carton, and FIG. 4 is a developed view thereof. A perforation X 'is provided on the side plate connected to both ends of the zipper, and a crease W is provided on the rear plate. When the container is opened by the zipper Z and separated at the separation perforations X 'provided on the left and right side plates, the container has a shape which can be resealed as a container having the folded rule W provided on the rear plate as a hinge. In the case of this example, a zipper is provided on the front plate, and a perforation X 'for separation is provided in connection with the zipper opening because of the opening method for resealability. The rear plate is provided with a hinge folding rule W connected to the separating perforation X '. As shown in FIG. 3 (C), a fold rule Y having a semicircular shape was provided on a side plate connected to the knob P. When the container is opened, a depression is formed on the back side of the gripper opening P of the zipper simply by lightly pressing the portion of the recess forming portion R with a finger, so that the zipper opening becomes easier to grip, and as a result, it is extremely smooth. Opening was possible, and the cut perforation X 'was cut off to obtain a resealable lid. Instead of the semicircular or other folded rule Y, a triangular folded rule Y as shown in FIG. 3B may be used.
