Abstract

A single-article packaging box that can be easily opened and where a door section is not deformed even if it is repeatedly opened and closed. The box has two parallel longitudinal slits (23) orthogonal to a folding line (f1) between the front door (17) capable of being opened and closed by hinge motion and a flap section (20) on the forward end side of the front door. Further, the box has folding lines (24, 26) for connecting the front ends and rear ends, respectively, of the two vertical slits (23), and also has a folding line (25) interconnecting intermediate portions of the two vertical slits (23) and located closer to the folding line (f1) between the front door (17) and the flap (20) than to the flap (20). When the flap (20) is bent to a right angle, a portion surrounded by the two vertical slits (23) is lifted up in a triangle to function as a finger hold section (27). To open the front door (17), a user engages their finger on the finger hold section (27) and pulls it in the opening direction. The front door (17) can be pulled without depressing the flap (20) and the front door (17) can be easily opened.

Technical field

TECHNICAL FIELD [0001] The present invention relates to an individual packaging box that is a product knockout, and more particularly to an individual packaging box that facilitates opening.

Background art

[0002] Individual packaging boxes based on cardboard or cardboard are widely used as product packages. There are various types of individual packaging boxes. One of the general packaging boxes is one in which the unfolded figure of the box is punched out of paper and assembled into a box shape, and at least one side is a door that can be opened and closed. is there.

FIG. 4A and FIG. 4B show an example of the individual packaging box. The individual box 1 shown in the figure is a door 2 whose one end surface in the longitudinal direction can be opened and closed in a hinged manner, and has a flap portion 3 in which the tip of the door 2 is bent at a right angle as shown in FIG. As shown in FIG. 4B, the flap portion 3 is inserted into the individual box 1 and the door 2 is closed. In addition, there is also a type in which linear slits 4 are cut at both ends of the folding line of door 2 and flap 3 and in this case, when door 2 is closed, slit 4 of door 2 is the side of the box (see figure). In this case, the door 2 does not open carelessly because it engages with the flap 5 provided at the edge of the upper and lower surfaces. When opening door 2, put your finger on flap 3 of door 2 and pull out the door, but it is difficult to insert your finger between flap 2 of door 2 and the side of individual box 1. As shown in Fig. 5, there are many cases in which a notch 6 is formed at the door side edge of the individual packaging 1 to make it easy to put a finger on the flap 3 of the door 2.

[0004] Another example of a packaging container described in Japanese Patent Application Laid-Open No. 52-45468 is a door that can be easily opened. This “packaging container” is a slit when the flap part is folded by adding a semi-circular or gate-shaped slit from the middle part of the folding line of the door and flap part to the flap part side. The enclosed part is not bent and is configured to be cut and raised in the same plane as the door. The cut and raised from the flap can be used as a finger when opening the door, and the door can be opened easily. It is something that can be done.

Disclosure of the invention [0005] The conventional individual box shown in FIGS. 4A and 4B has a drawback that it is difficult to insert a finger between the flap portion and the side of the box when the door is opened. As shown in Fig. 4A, Fig. 4B, and Fig. 5, when the door is opened, the flap part must be touched with a finger. It will be pushed down, and it will be difficult to open the flap part of the door by hooking it on the back side of the flap part on the box side. Further, in the case where the door is provided with a slit in the flap portion, the slit is more difficult to open because it engages deeper with the flap portion on the box side. Therefore, force is required to open the door, and the flap part of the door and the flap part on the box side may be damaged. Individual packaging boxes are often discarded after opening, but for example, for the purpose of product explanation and content confirmation, the individual packaging boxes may be stored again after taking out the individual packaging strength products. Desirable, so as not to break.

[0006] The "packaging container" described in Japanese Patent Laid-Open No. 52-45468 has a cut-and-raised integral with the door, so that the door can be pulled in the opening direction without pushing down the flap part. However, depending on the thickness of the paper base material, the flat cut-and-raised part may not be strong enough to function as a finger hook. In addition, the vertical rise from the corner of one end of the box may be an obstacle when packing multiple “packaging containers” into the packing box.

[0007] Therefore, a technical problem to be solved arises in order to provide an individual packaging box that can be easily opened and that does not deform or break even when it is repeatedly opened and closed, and the present invention solves the above problems. The purpose is to do.

[0008] The present invention is proposed in order to achieve the above object, and is a box formed by folding a sheet of paper or grease, and at least one surface is a door that can be opened and closed in a hinged manner. In an individual packaging box that has a flap part that is bent inward, and that is inserted into the box to close the door, two parallel parts perpendicular to the folding line of the door and the flap part A fold line that forms a slit and connects the front and rear ends of the two slits, and a fold line that connects the middle part of the two slits and is displaced closer to the flap part than the fold line of the door and the flap part. When the door and the flap are bent at a right angle, the part surrounded by the two slits rises into a triangle and becomes a finger hook, and the door is closed. Make a notch on the side of the box to expose the finger There is provided a unit package container, characterized in that formed on. [0009] In the individual packaging box of the present invention, a finger-hanging portion raised in a triangular shape is formed at the flap portion at the tip of the hinge-type door, and the door can be easily pulled by placing a finger on the finger-hanging portion. In addition, by providing a finger hook, the door can be pulled in the opening direction without pressing down the flap, so unlike the conventional type, the door flap is hung on the back side of the flap on the side of the box. In most cases, the slit of the crease between the door and the flap part will be deeply engaged with the flap part on the box side, and the door and flap part will not be obstructed and the door or flap part will be deformed or damaged. Absent.

BEST MODE FOR CARRYING OUT THE INVENTION

[0011] The present invention relates to an individual packaging box having a door that can be opened and closed in a hinged manner, in which two parallel slits perpendicular to the fold line between the door and the flap at the tip of the door are formed, and the two slits The fold line connecting the front end and the rear end of the door and the middle part of the two slits are connected, the fold line displaced to the flap part side of the door and the fold line of the flap part is processed, and the door and the flap part are connected. When folded at right angles, the part surrounded by the two slits rises into a triangle and forms a finger-hanging part, and the box has a notch to expose the finger-holding part when the door is closed By achieving the individual box formed on the side of the box, it was easy to open, and the purpose of preventing the box from being deformed or damaged even when the door was opened and closed repeatedly was achieved.

FIG. 1 is a development view of the individual packaging box 11 of the present invention. The top, bottom, left, and right four sides 12, 13, 14, and 15 are continuous in the figure, where 12 is the right side, 13 is the top, 14 is the left side, and 15 is the bottom. Moreover, the broken line has shown the fold line f which was press-processed. [0013] A margin 16 is provided on the lateral edge (upper in FIG. 1) of the right side surface 12, and the front door 17 is continuous with the front edge (right in FIG. 1). A rear door 18 is connected to the rear edge of the left side surface 14 (left in FIG. 1), and a flap portion 19 is connected to the front and back of the top surface 13 and the bottom surface 15 (left and right in FIG. 1). Yes. The front and rear doors 17 and 18 have fold lines fl and f2 in the vicinity of the front ends of the flaps 20 and 21, respectively, and flaps 20 and 21 are located at both ends of the fold lines fl and f2. 22 is processed. The slit 22 may be a structure in which the flaps 20 and 21 are simply bent without providing the slit 22 which is not essential.

[0014] In the vicinity of the front end of the front door 17, two vertical slits 23 perpendicular to the folding line fl are processed, and the front ends of the two parallel vertical slits 23 (right in Fig. 1). Three fold lines 24, 25, 26 connecting the rear end and the vicinity of the front end are pressed. A rectangular area surrounded by the two vertical slits 23, a fold line 24 connecting the front ends, and a fold line 26 connecting the rear ends becomes a hook portion 27 described later. A notch 28 having a width substantially equal to the interval between the two vertical slits 23 of the front door 17 is formed in the front edge 14a (right in FIG. 1) of the left side surface 14.

[0015] FIGS. 2A, 2B, and 2C show a state where the unfolded individual box 11 of FIG. 1 is assembled into a box shape, and FIG. 2A is still bent the flap 20 at the front end of the front door 17. It is not in a state. Then, as shown in Fig. 2B and Fig. 3, when the flap 20 at the front end of the front door 17 is bent at a right angle, the finger hook 27 also bends at the three folding lines 24, 25, 26 described above. Since the fold line 25 in the middle of the portion 27 is displaced to the tip side from the fold line fl of the flap portion 20, the position of the apex of the finger hook portion 27 is more on the tip side than the corner between the front door 17 and the flap portion 20 ( Displace to flap side). In other words, the surface force of the folded flap portion 20 also has a shape in which the apex of the finger rest portion 27 is raised.

[0016] As shown in FIG. 2C, when the flap portion 20 is inserted into the inside of the left side surface 14 of the individual packaging box 11 in the state of being assembled into a box shape, the finger hook portion 27 enters the notch 28 of the left side surface 14 and the front side. The door 17 is closed, and the slits 22 at both ends of the flap portion 20 are engaged with the top surface 13 and the flap portion 19 of the bottom surface 15 so that the front door 17 is held closed.

[0017] When opening the front door 17, it is possible to pull the front door 17 without pushing down the flap portion 20 by placing a finger on the finger-hanging portion 27 protruding like a triangular rib and pulling it in the opening direction. The front door 17 can be easily disengaged from the flap portion 20 of the front door 17 and the top surface 13 and the flap portion 19 of the bottom surface 15. 17 is released.

[0018] In this manner, when the door is opened, an excessive force is not applied to the flap portion 20 and the top surface 13 of the front door 17 and the flap portion 19 of the bottom surface 15. The wrinkles in which 19 and 20 are deformed or damaged are significantly lower than conventional products.

[0019] When a plurality of individual packaging boxes 11 are packed side by side in one packing box, the top of the finger hook portion 27 hits the side surface of the adjacent individual packaging box 11 and the finger hook portion 27 and the flap portion 20 are pushed down. Therefore, it is possible to pack the individual boxes 11 closely. At this time, if the individual packaging 11 is taken out of the packing box where the finger hook 27 is not damaged or deformed, the finger hook 27 and the flap 20 will be in the initial state of FIG. Restore to.

[0020] It should be noted that the present invention is not limited to the above-described embodiments, and various modifications are possible within the technical scope of the present invention, and it is natural that the present invention extends to those modifications. .
