Description

  The present invention relates to a cylindrical container having an opening structure, and in particular, at least the barrel is preferably made of paper, and the top and bottom are preferably made of paper, plastic, metal, and the like. Preferably, the present invention relates to a cylindrical container having an opening structure having a substantially cylindrical shape.

As a method for opening the cylindrical container, for example, as described in Patent Document 1 (Japanese Patent Laid-Open No. 2004-26178), a method of providing a specific zipper structure and opening the container, Patent Document 2 (actual opening) As described in JP-A-53-164547, there is a method of providing a picking tongue piece and opening it by pulling or pushing.
Thus, there are a zipper type and a push type as a container opening method. The zipper type is inconvenient for consumers because the cut portion becomes garbage after cutting. On the other hand, the push type can be opened with two actions and is convenient for consumers.
However, when the push type is adopted as the method of the cylindrical paper container, especially when designing with a cutting blade having the necessary distribution strength and the length of the tablage, the container is not opened before the tablage is cut due to the flexibility of the paper. There is a risk that the contents will be damaged.
Moreover, after pushing in and putting a finger, when pulling up an upper part, it will tear a trunk | drum from the recessed part, and will become difficult to open.

  The problem to be solved is that the opening structure of the cylindrical container significantly damages the container and damages the contents. SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a cylindrical container having an opening structure that can be easily opened by a consumer without significantly damaging the container and without damaging the contents.

The present invention is a cylindrical container having an opening structure,
On the peripheral surface of the cylindrical container, a zipper part including a substantially arc-shaped push part is provided,
Provided with an opening structure provided with a substantially arc-shaped folding part having a ruled line on the opposite side of the push part, the zipper part is inclined to the left and right from both ends of the push part, and a linear part continuous thereto And a tip of the folded portion is in contact with a straight portion of the zipper portion .
In this case, it is preferable that the push part is a perforation.
Moreover, it is preferable that the said folding part consists of ruled lines.
And it is preferable that the said folding part has a larger arc-shaped diameter than the said push part.
Moreover, it is preferable to provide the folding ruled line which made the said zipper part one end on the surrounding surface of a cylindrical container.

According to the opening structure of the cylindrical container of the present invention, the container body is not recessed by the push part having a perforation formed by a convex shape, particularly an arc shape, preferably a semi-circular shape with a cutting blade and a jumper. From the upper end of the zipper part, it is possible to open the zipper part which is preferably inclined slightly upward and downward from the semicircular upper end, and preferably at the upper part of the semicircular push part and the zipper part. Drawn, upside down from the push part, with a fold part composed of convex, in particular arc-shaped, preferably semicircular ruled lines (or ruled lines and half-cut), in particular the upper part by this fold part When opening by pulling up, it has the advantage that it becomes possible to open without tearing the trunk. With this structure, the consumer can easily open the cylindrical container without significantly damaging the contents and without damaging the contents.
Further, the re-encapsulation part is formed by folding with a ruled line and the diameter becomes narrower (smaller), so that it becomes easy to enclose again after opening the container.

As an opening structure of a cylindrical container, a structure that does not significantly damage the container, does not damage the contents, and can be easily opened by the consumer, has been proposed. It was. FIG. 2 shows the features of FIG. 1 in more detail.
And the feature point is as follows.
(1) Preferably, it has a push portion A composed of a perforation composed of a cutting blade and a jumper in a substantially semicircular shape,
(2) Preferably, an inclined zipper part B is provided slightly above and to the left and right of the semicircular upper end part,
(3) The upper part of the semicircular push part A and the zipper part B is drawn from the upper end of the zipper part B. The push part A is preferably a semicircular ruled line (or ruled line The opening structure of the cylindrical container provided with the folding part C comprised by cutting.

The cylindrical container 10 according to the present invention is preferably a cylindrical paper container having an approximately cylindrical shape in which at least the trunk is made of paper and the top and bottom are made of paper, plastic, metal, and the like. .

As shown in the figure, the perforation of the push portion A, that is, the cut line, is preferably a structure in which the lowermost part of the semicircle, that is, the part where the force is most applied first at the time of pushing is the cutting edge 21 and then the tab 25 is provided. Note that the push portion A is provided with ruled lines 27 as virtual horizontal lines in order to facilitate bending. When the back pasting portion 18 is present, the push portion A is positioned so that the end of the paper on which the back pasting portion 18 overlaps is located at the center of the unsealing structure, as shown in FIG. It is desirable that the opening structure is located in the direction opposite to the sticking portion 18. In short, it is desirable that the back pasting part 18, in other words, the strong part comes at the beginning or end of the opening, and if there is the back pasting part 18 in the middle, it is difficult to balance the left and right of the opening, and the paper is produced. The problem is likely to occur.
In this case, the push portion A only needs to be provided in a convex shape, that is, in an arc shape with respect to the zipper portion B. In the illustrated example, the push portion A is formed in a semicircular shape. Further, it may be a polygonal shape such as a square or a shape having R at its corners.

In the illustrated example, the zipper portion B is formed in a half-cut 31 having a dogleg shape.
And this zipper part B is formed in the circumferential shape over the substantially whole region on the surrounding surface of a cylindrical container.
A push portion A is provided at a predetermined location of the zipper portion B. It is preferable that the start portion of the zipper portion B is inclined with respect to the push portion A at a predetermined angle. The illustrated angle θ of the virtual horizontal line 27 of the push part A with respect to the perpendicular of the starting position of the zipper part B is preferably 105 ° to 130 °. Thereby, reliable opening is attained. When the angle θ is other than this, there is a tendency that the opening cannot be smoothly performed. This is because if the leading end of the push part A is in direct contact with the starting end of the zipper part B, the opening tends to be difficult.

Furthermore, the folding part C has a larger diameter than the push part A. Thereby, reliable opening is attained.
The folded portion C comes into contact with a predetermined position of the zipper portion B. If there is an arc tip of the folding part C in the middle of the inclination of the zipper part B, the folding part C does not dent in an arc shape but is dented from the tip of the zipper part B (that is, the part intersecting the straight part of the zipper part B), This is because there is a tendency that the upper part of the paper is smeared along the eyes and then torn.
Conversely, if the tip of the folded portion C is in the straight part of the zipper part B, there is a tendency that the part of the zipper part B where the tip of the zipper part B and the straight part of the zipper part B intersect is not easily broken. Further, if the crossing portion is omitted, the strength of the zipper portion tends to be weakened.
In the illustrated example, the folding part C is formed from the perforation of the half-cut 41 and the ruled line 43. However, when the folded part C is not only the ruled line, the blade combination is such that the part that intersects the zipper part B is a half-cut blade. A ruled line is desirable. This is because if there is a blade at the intersecting portion, the paper from the blade portion will be peeled off at the time of opening, which makes no sense.

Furthermore, in the structure of the illustrated example, an example in which a re-encapsulation portion F is added is shown.
As shown in the figure, the re-encapsulating portion F is preferably three ruled lines 51, 52, and 53 that form a triangular ridge line and a center line that contact the lower side of the zipper part B in this case. Is preferred.

In such a configuration, when the push part A is pushed with a finger, the folding part C bends and the zipper part B is broken at the same time as shown in FIG. When it is desired to re-enclose the contents again after opening, it can be folded back along the ruled line of the re-encapsulating portion F to easily return to the original shape. The ruled lines 51, 52 and 53 are bent to form the re-encapsulation part F. By forming the re-encapsulating portion F, the diameter becomes small and can be easily covered. Although only one re-encapsulation part F can be provided, it is preferable to provide two re-encapsulation parts F and F at positions facing each other as shown in the figure. This position is provided at a position different from the push part A and the folding part C as shown in the figure.

In the structure shown in the figure, it was found that the size of the opening structure is easy to open when the push portion A has a radius of about 11 mm and the folding portion C has a radius of about 24 mm with respect to a cylindrical container having a diameter of 75 mm.

In a product stored in a cylindrical paper container, an unsealing structure that does not damage the container itself and its contents is realized, which is useful in such applications.

It is an expanded view for demonstrating the opening structure of this invention. It is an expansion expanded view for demonstrating in more detail the opening structure of this invention. It is a perspective view for demonstrating the opening state of the opening structure of this invention.
