Description

  The present invention is a package that can be opened easily, the number of wastes does not increase by opening, and the stored goods are clearly understood to be opened and the stored goods can be removed during transportation, storage, exhibition, replacement, replacement of foreign objects, etc. Concerning the container.

  In the field of pharmaceuticals and food packaging, there are many damages caused by tampering when merchandise is extracted during transportation, storage, and display and replaced. A zipper is used to prevent these tampering and easy opening, but the conventional zipper requires extra disposal work because the strips are separated and the number of waste increases at the time of opening, This is a problem especially in the field of emergency medicine. For this reason, there has been proposed a packaging container that has a zipper that changes the opening method between a normal time and an emergency, and uses an opening method that does not separate strips in an emergency (Patent Document 1). This technique has a problem that it cannot be properly opened because it is confused because the opening method in an emergency and the opening method in an emergency are different. In addition, a technique has been proposed in which a pick piece (the above-mentioned band-like piece) is not separated when opening with a zipper (Non-Patent Document 1). Since this technology has long continuous cuts in the curved part of the zipper, the cut part is caught and broken when the packaging container is manufactured and stored, or when a product is filled in the packaging container, or the packaging container is deformed. There is. Further, it is necessary to widen the width of the portion of the packaging container where the zipper is provided, and there is a problem that the shape of the packaging container is limited and cannot be used for many packaging containers. Moreover, although it starts by pushing the packaging container folded flat at the time of goods filling from both sides, there exists a problem which a packaging container does not stand up easily when there is a long cut part.

Opening is easy, no extra waste is generated at the time of opening, traces of opening remain clearly, and no unauthorized opening is missed, and the opening method is determined in a single way, preventing confusion at the time of opening, To provide a packaging container that can be easily broken as designed because the force is applied in the direction in which the zipper is likely to break, the packaging container is easy to manufacture, and there is no occurrence of breakage, deformation, or failure when filling the contents. That is.

The present invention
(1) A zipper for opening is provided at a site of the packaging container, and the zipper is constituted by a first predetermined break line and a second predetermined break line in which penetrating portions and non-penetrating portions are alternately arranged. The two break lines are broken by pulling with the ends of the band-shaped portion sandwiched between the planned break line and the second planned break line, but the above-mentioned part is separated into two or more by the break of the first planned break line The packaging container in which one end of the part is not broken even by the breaking of the second scheduled breaking line and the band-shaped part is not separated from the packaging container main body, and has a break stop structure at the second scheduled breaking line. Packaging container.
(2) The rupture stop structure is any of a two-dimensional shape penetration structure or concavo-convex structure and a penetration structure or concavo-convex structure in a direction inclined by 30 to 150 degrees with respect to the rupture direction of the second planned break line. The packaging container according to item 1.
(3) The penetrating portion of the second planned breaking line has a straight portion parallel to the breaking direction and a front oblique portion extending obliquely at an obtuse angle at the front end of the straight portion, and at least a part of the penetrating portion of the second planned breaking line The packaging container according to item 1 or 2, wherein the front oblique line part is directed in the opposite direction with respect to the first predetermined fracture line.
.

The packaging container of the present invention is a packaging container that stores products such as pharmaceuticals, cosmetics, foods, etc. inside and has a buffering action to protect the products. A packaging container formed by punching and folding one blank plate is preferable. A paperboard or the like is punched into a predetermined development shape, creased ruled lines are formed, each part is folded at the crease part, and further adhered with an adhesive if necessary. Preferred shapes of the packaging container are a sack box, a one-touch bottom, a hell bottom, a carry case, and a four corner, with a sack box and a one-touch bottom being particularly preferred. There is no restriction | limiting in particular in the material of a packaging container, A paperboard and a cardboard can be used, and a paperboard is more preferable. As the paperboard, a non-coated ball, a coated ball, a manila ball, a yellow paperboard, and a colored paperboard can be used, but the non-coated ball and the coated ball are more preferable, the coated ball has a high strength, and is excellent in printability. And most preferred. The thickness of the paper is preferably 150~750g / ^{m 2} in basis weight, more preferably ^{230~680g / m 2, 230~500g / m} 2 is most preferred. If the basis weight of the paper is too small, the strength of the packaging container is insufficient and the stored product cannot be sufficiently protected, and if it is too large, the processing is difficult and the price increases, which is not preferable.

  An opening zipper is provided on at least one packaging container. This site | part is a site | part which forms the outer surface of packaging containers, such as a face plate, a flap, and a tack. The part where the opening zipper is provided may be any part as long as the packaging container sealed by breaking the part by the zipper can be opened.

The opening zipper of this invention is demonstrated in FIG. The zipper 2 includes a first planned break line 3, a second planned break line 4, and a belt-like portion 5 sandwiched between the two planned break lines 3 and 4. Both planned break lines have a structure in which penetrating portions 6 (cut portions) and non-penetrating portions 7 are alternately arranged. The penetrating portion 6 is usually formed by applying pressure to the Thomson blade. By holding and pulling the end portion 9 of the belt-like portion 5, both planned break lines are broken, and by breaking the first planned break line 3, a part of the packaging container is separated and the packaging container is opened. Even when the second planned breaking line 4 is broken, one end of the portion is not broken, and the band-like portion is not separated from the packaging container body.
FIG. 2 shows the packaging container 1 of the present invention before opening, and FIG. 3 shows the packaging container 1 of the present invention with the zipper broken. As shown in FIG. 3, the band-like portion 5 is not separated from the packaging container 1 by the opening operation. Therefore, it is preferable that no extra waste is generated by the opening operation. In particular, since there is no room for cleaning up garbage in an emergency, it is a great advantage that the band-like portion 5 does not separate from the packaging container body.

The break stop structure 8 provided at the terminal portion of the second planned break line 4 is not particularly limited as long as the break is stopped. As a preferable breaking stop structure, there are a penetrating structure or a concavo-convex structure having a two-dimensional area, and a penetrating structure or a concavo-convex structure in a direction inclined by 30 to 150 degrees with respect to the breaking direction of the second planned breaking line.

An example of a through structure having a two-dimensional area is shown in FIG. Preferred shapes of the penetrating structure or the concavo-convex structure having a two-dimensional area include a circle, an ellipse, a part of a circle, a part of an ellipse, a polygon, a quadrangle, and a triangle. A more preferable shape is a shape that does not have a sharp bend in the peripheral shape such as a circle, an ellipse, a part of a circle, or a part of an ellipse. By not having an acute angle bend, the stress at the time of rupture is diffused and the progress of the rupture is easily stopped, which is preferable. Area of the through portion or uneven structure is preferably 0.7～200Mm ² having a two-dimensional area, more preferably 1.5~50mm ^2, 4~50mm ² is more preferable. . The penetration structure can be formed by punching the packaging material with a mold or blade. The penetrating structure is preferably either one continuous penetrating structure or an assembly of a plurality of holes. A continuous through structure is more preferable from the viewpoint of ease of manufacture and appearance after opening. The uneven structure can be formed by pressing the mold against the packaging material. The concavo-convex structure is a structure in which one side of the member of the packaging container is convex and the opposite side is concave by pressing the mold. 0.1-2 mm is preferable and, as for the height of a convex part, 0.5-1.5 mm is more preferable. . If the height is too low, the force for stopping the breakage is weakened, and if it is too high, it may cause damage during production, which is not preferable. The convex portion is preferable on either the outer surface or the inner surface of the packaging container, but more preferably on the outer surface. In addition, the concavo-convex structure is preferably one in which the peripheral edge is convex and the inner side is concave, and conversely, the one in which the peripheral edge is concave is preferable, but the one in which the peripheral edge is convex and the inner side is concave is more preferable.

Another preferable structure of the break stop structure is a through structure or an uneven structure in a direction inclined by 30 to 150 degrees with respect to the break direction of the second planned break line. An example of a penetrating structure having an angle α is shown at 8a in FIG. The breaking direction of the second planned breaking line 4 is the tangential direction of the final repeating unit of the repeating unit of the penetrating structure and non-penetrating structure of the second scheduled breaking line. The angle α is preferably 30 to 150 degrees, and more preferably 40 to 130 degrees. Even if the angle α is larger or smaller than this range, the direction of the penetrating structure or the concavo-convex structure is almost parallel to the breaking direction, and the force for stopping the breaking is reduced, which is not preferable. As the shape of the penetration structure or the concavo-convex structure, a shape having a short penetration portion such as a cut structure or a perforation is also preferable. The breaking stop structure is preferable whether it is connected to the penetrating portion 6 of the second planned breaking line 4 or not. The width of the penetrating structure or the uneven structure is preferably 0.5 to 5 mm, more preferably 1 to 3 mm. If the width is too narrow, the force for stopping the breakage will be weak, and if it is too wide, it will cause damage during the production of the packaging container. 2-10 mm is preferable and, as for the length of this penetration structure or this uneven structure, 3-8 mm is more preferable. When the length is too short, the force for stopping the breakage is weakened, and when the length is too long, the appearance of the packaging container is deteriorated.

A preferable breaking stop structure is a penetrating structure or a concavo-convex structure having a two-dimensional area, or a penetrating structure or a concavo-convex structure in a direction inclined by 30 to 150 degrees with respect to the breaking direction of the second planned breaking line. The penetration structure has a larger breaking stop force and is more preferable than the concavo-convex structure. The penetration structure having a two-dimensional area has a larger breaking stop force and is more preferable than the penetration structure in a direction inclined by 30 to 150 degrees with respect to the breaking direction of the second planned breaking line.

The average distance between the first planned break line 3 and the second planned break line 4 is preferably 3 to 30 mm, more preferably 4 to 20 mm, and even more preferably 4 to 15 mm. If the interval is narrow, it is not preferable because the band-like portion 5 of the zipper tears in the middle when opening and the zipper breaks in the middle. Moreover, if it is too wide, it becomes necessary to increase the area of the part of the packaging container 1 where the zipper is provided, and when pulling the end portion 9 of the band-like portion 5 by hand, the breaking direction of the zipper tends to change and the breaking stops halfway. It is easy and not preferable. Of course, the length of the zipper depends on the size of the packaging container, but is preferably 10 to 300 mm.

4-25 mm is preferable, as for the size of the penetration part 6 of both planned breaking lines 3 and 4, 6-20 mm is more preferable, and 6-15 mm is especially preferable. If this size is too small, machining with a Thomson blade becomes difficult, failure that does not penetrate occurs, and resistance when pulling the zipper increases, which is not preferable. Moreover, since the intensity | strength of a packaging container will fall when too large, it is unpreferable. The size of the non-penetrating part 7 of both planned break lines 3 and 4 (defined by the shortest straight line distance between the nearest penetrating parts) is preferably 1 to 5 mm.

In the opening zipper of the present invention, the length of the longest penetrating portion 6 of the second planned breaking line 4 is preferably 1 to 3 times the average length excluding the longest and shortest of the penetrating portion 6. The length of the penetrating portion 6 of the second planned breaking line 4 is the length along the shape of the continuous penetrating portion 6, and when the shape is a curve, it is the length along the shape of the curve. Moreover, when it bends in a straight line, it is the total length of the straight part of the connected penetration part. In the case of the shape as shown in FIG. 1c, it is the sum of l1, l2, l3 and l4. The shape of the penetrating portion 6 can be preferably used as a straight line or a curved line. If the length of the longest penetrating portion of the second planned break line 4 is too long, the strength of the packaging container portion is lowered, and it may be damaged when the packaging container is manufactured, stored, transported, or filled with goods. Further, when the packaging container is flatly folded at the time of product filling, the packaging container is pushed up from both sides to form a three-dimensional shape. However, if there is a long penetrating portion, there is a problem that the packaging container is easily warped and does not rise.

As shown in FIG. 5g, the penetrating portion of the second planned break line 4 has a straight line portion 31 parallel to the break direction and a front oblique line portion 32 extending obliquely at an obtuse angle at the front end of the straight line portion. It is preferable that at least a part of the front oblique line portion 32 of the four through portions is directed in the opposite direction with respect to the first predetermined fracture line 3. As a result, the first planned break line 3 is preferably broken earlier than the second planned break line 4 so that the packaging container can be easily separated.

The length of the repeating unit 10 of the penetration part and the non-penetration part of both the planned break lines 3 and 4 may be different in the same planned break line. It is preferable that one planned breaking line has 4 or more repeating units. It is preferable that the average length excluding the longest portion of the repeating unit of the penetrating portion and the non-penetrating portion of the first planned breaking line 3 is 1.0 to 2.5 times the average length of the second planned breaking line 4. 1.2 to 2.0 times is more preferable, and 1.4 to 1.8 times is more preferable. As a result, the first planned break line 3 breaks faster than the second planned break line 4, the part is divided into two or more by the break of the first planned break line 3, and the second planned break line 4 breaks. Are not separated, and the zipper strip 5 is not separated from the packaging container 1 body, which is preferable. If the value of the average length ratio is too large, the strength of the packaging container 1 decreases, which is not preferable. If it is too small, the break of the first planned break line 3 will not be sufficiently faster than the break speed of the second planned break line 4 and the break of the first planned break line 3 will be completed by the end of the break of the second planned break line 4. It is not preferable because it cannot be opened.
A preferred example of the shape of the repeating unit 10 of the two scheduled break lines 3 and 4 is shown in FIG. The shape of the repeating unit of both planned break lines may be the same or different. It is also preferred that both planned break lines have a plurality of different repeating unit shapes.

It is preferable that the second planned break line 4 is disposed on the lower side or the near side as viewed from the opening operator with respect to the first planned break line 3. When an operator pulls the belt-shaped portion 5, it is easy to apply a force to the lower side or the near side. Therefore, if the second planned break line 4 is on the lower side or the near side, the first planned break line 3 is surely broken. This is preferable.

  The sealing method of the packaging container 1 is not particularly limited, but a method of inserting the insertion piece into the guide slit, a method of sticking a sealing tape, a method of bonding with an adhesive, and a method of bonding by mechanical means such as a staple are used. Can do.

In order to make it easy to pick the zipper, it is preferable to provide an opening for the finger to enter the end 9 of the zipper or its adjacent portion. There is no restriction on the shape of the opening, but it needs to be large enough to fit an adult's finger. The height of the opening is preferably 3 to 20 mm, more preferably 5 to 15 mm, and even more preferably 7 to 12 mm. If the height is too small, the fingers do not enter, and if it is too large, the strength of the packaging container is lowered and it is easy to break. The width of the opening is preferably 10 to 40 mm, more preferably 12 to 30 mm, and still more preferably 15 to 25 mm. If the width is too small, the fingers do not enter, and if it is too large, the strength of the packaging container is lowered and it is easy to break. The shape is preferably a part of an arc from the viewpoint of easy finger insertion and strength of the packaging container.

An example of the packaging container of the present invention will be described with reference to FIG. The outer upper surface plate 41 has the opening zipper 2, and the zipper has a break stop structure 8 a at the end of the second planned break line 4. The left and right side plates 43, 45, the front plate 46, and the back plate 44 are folded along a ruled line, and an adhesive is applied to the front side of the adhesive allowance 47, and is attached to the back side of the right side plate 43. Further, the upper and lower side flaps 48a, b, c, d Was folded at the ruled line. At the same time, the paste was applied to the back surfaces of the adhesive margin bottom pieces 50a and 50b and adhered to the surfaces of the lower surface flaps 49a and 49b, respectively. The lower surface plates 49a and 49b are pushed downward from the inside of the packaging container to form a three-dimensional box. After storing the product, the inner upper surface plate 42 is bent along a ruled line, and the outer upper surface plate 41 is placed on the inner upper surface plate 42. Adhere to and seal. An adhesive was applied to the back side of the upper end portion on the development view of the outer upper surface plate, and attached to the lower end portion on the development view of the inner upper surface plate 42. When the end portion 9 of the zipper 2 is picked and pulled to break the first planned breaking line 3, the upper surface plate 41 is separated into two and can be opened. At this time, the second planned break line 4 is preferably broken without being separated from the packaging container 1 because the break is stopped by the break stop structure 8a.

Opening is easy, no extra waste is generated at the time of opening, traces of opening remain clearly, and no unauthorized opening is missed, and the opening method is determined in a single way, preventing confusion at the time of opening, To provide a packaging container that can be easily broken as designed because the force is applied in the direction in which the zipper is likely to break, the packaging container is easy to manufacture, and there is no occurrence of breakage, deformation, or failure when filling the contents. I was able to. In particular, since the rupture stop structure is provided at the second planned break line, the zipper where the band-like portion is not easily separated can be opened by natural operation. Because the zipper strip does not separate from the packaging container, it can be re-sealed by pushing the strip and the container can be re-sealed. The protection was possible, and the belt-shaped portion was deformed, so it was clearly known that it was opened, and it was preferable to prevent illegal removal, replacement, and contamination of stored items.
