The present invention has been made to solve such a problem, and at least the shape of the product accommodated in the main body can be confirmed from the outside, and foreign matter entering from the outside does not adhere to the accommodated product. An object of the present invention is to provide a packaging container.
[0006]
[Means for Solving the Problems]
According to the first aspect of the present invention, in the invention of claim 1, a box-shaped packaging container made of a thin plastic material that is transparently formed to such an extent that the external shape of the product can be visually recognized from the outside in a state in which the product is accommodated inside. An opening having at least a plurality of sides provided at an upper end of the box-shaped main body, a first extension formed by extending one side of the opening integrally by a predetermined distance, and the first A second extension portion further extended than the extension portion of the first extension portion, and the second extension portion is folded inward so that the tip end portion of the second extension portion reaches the inside of the main body from the opening. The header portion having a latching portion in the substantially central region in the width direction and the sides on both sides sandwiching the side provided with the header portion are integrally extended, and the respective extensions are folded inward. The tongue piece that forms the inner lid at the front, The side opposite to the side on which the header part is provided is integrally extended, the extension part is folded inward and covered on the inner lid, and the extended end part is at a position to be the base end of the header part. A lid that has a length that is bent so as to reach the inside of the main body from the opening, and has a peripheral edge that is disposed in the main body and inscribed in the inner wall of the main body, at least on the header part side A packing member that is an extended peripheral edge extended to the header side, and at least an inner surface that is folded inward as described above in the second extended part of the header part, A configuration in which the extended peripheral edge portion of the packing portion abuts, an outer surface of the header portion that is folded back inward as described above, and the extended end portion of the lid body abuts. Achieved by packaging containers It is.
[0007]
According to the structure of claim 1, since the packaging container of the present invention is formed of a thin plastic, it is easy to form it transparently, and even if it is printed with color, the color is good, and the product It can be formed transparent to such an extent that the outer shape of the can be visually recognized. In addition, it is strong compared to paper or the like, and has excellent rigidity. Articles or goods can be taken in and out through the opening at the upper end of the container body of the packaging container. One side of this opening is extended to form a header portion having a latching portion in a substantially central region in the width direction, and each side of the both ends is extended to provide each tongue piece portion. For this reason, by folding each tongue piece inwardly and forming an inner lid, foreign matter such as external dust hardly penetrates into the main body at least from the region of the base end portion of each tongue piece.

[0012]
According to a fourth aspect of the present invention, there is provided a box-shaped package made of a thin plastic material that is transparently formed so that the outer shape of the product can be visually recognized from at least the outside in a state in which the product is accommodated. An opening provided at the upper end of the box-shaped main body and having at least a plurality of sides; a first extension formed by extending one side of the opening integrally by a predetermined distance; A second extension portion further extended from the first extension portion, and the second extension portion is folded inward so that the tip end portion of the second extension portion reaches the inside of the main body from the opening. As a configuration, a header portion having a latching portion in a substantially central region in the width direction and sides on both sides sandwiching the side provided with the header portion are integrally extended, and the respective extended portions are folded inward. The tongue piece that forms the inner lid The side opposite to the side where the header portion is provided is integrally extended, the extension portion is folded inward and is put on the inner lid, and the extended end portion becomes the base end of the header portion. A lid that has a length that is bent to reach a position and is inserted so as to reach the inside of the main body from the opening, and the extension end portion of the header portion is an inner portion of the opening portion at a tip portion. This is achieved by the packaging container provided with a housing portion for housing the extended end portion of the lid body by being folded back to the side.
[0013]
According to the structure of claim 4, since the packaging container of the present invention is formed of a thin plastic, it is easy to form transparently, and even if it is printed with color, the color is good, and the product It can be formed transparent to such an extent that the outer shape of the can be visually recognized. In addition, it is strong compared to paper or the like, and has excellent rigidity. Articles or goods can be taken in and out through the opening at the upper end of the container body of the packaging container. One side of this opening is extended to form a header portion having a latching portion in a substantially central region in the width direction, and the side portions at both ends thereof are extended to provide each tongue piece portion. For this reason, by folding each tongue piece inwardly and forming an inner lid, foreign matter such as external dust hardly penetrates into the main body at least from the region of the base end portion of each tongue piece. Further, by performing predetermined printing using the front surface of the header portion or the like, the display effect is enhanced, and the product can be displayed by being suspended by the hooking portion.
In addition, a housing portion is formed by the extension end portion on the header portion side being further folded back to the opening side at the tip portion, and the extension end portion of the lid body enters the housing portion, so that the header portion and the lid The gap between the opening and the body is difficult to form, and even when foreign matter such as dust enters, the foreign matter stops in the header side housing, so the product as the contents is stored cleanly The

As a result, the packaging container 10 can be easily formed transparently, and even when printing with color is performed, the color is good, and the packaging container 10 can be transparently formed so that the outer shape of the product can be visually recognized. it can. In addition, it is stronger and more rigid than paper or the like, and thus it has excellent rigidity and protects the contents reliably.
[0016]
As shown in FIGS. 1, 2, and 4, the main body 11 is, for example, a hollow rectangular parallelepiped that is long in the vertical direction, and includes an opening 12 at the upper end as shown in FIG. 4.
As shown in FIG. 3, the lower end of the main body 11 is provided with extension portions 71, 72, 73, 72 that are extended from the respective sides to have a predetermined shape, and extend along the lower end of the main body 11. The bottom of the main body 11 is closed by being folded inward along each side.
[0017]
As shown in FIG. 1, the packaging container 10 is configured to accommodate, for example, a product B such as a sucker or a beverage cup. In this embodiment, the size of the main body 11 is planned to be accommodated. Corresponding to the size of a plurality of products B, it is formed slightly larger than these.
[0018]
As can be understood with reference to FIGS. 1, 3, and 4, a header portion 20 is formed on the side 13 that forms the periphery of the opening portion 12 located on the back side of the product accommodated in the main body 11. ing. The header portion 20 has a first extension portion 21 and a second extension portion 23 obtained by further extending the main body 11 as a portion integrally extending upward from the side 13 with the same width as the side 13. doing. The boundary between the first extension portion 21 and the second extension portion 23 is a bent portion 22 parallel to the side 13, and the second extension portion 23 is located on the opening 12 side in the bent portion 22. (See FIG. 3).
[0019]
Since the side 13 is not bent in the assembled state of FIG. 1, the first extension 21 is erected vertically, and the bent portion 22 is the highest portion of the packaging container 10. The second extension portion 23 is a folded tip portion and extends longer than the first extension portion 21 so that the most distal end portion 24 enters the main body 11 when bent inward at the bent portion 22. (See FIGS. 4 and 3).
The first extension portion 21 and the second extension portion of the header portion 20 are provided with holes so as to pass through these same locations in the state of FIG. . In the case of this embodiment, the latching portion 25 is a so-called airplane hole, and is formed by combining a large hole and a latching hole 26 that is formed smaller than this and extends upward.
[0020]
Thereby, as shown in FIG. 2, by inserting the hook 61 for latching into the large hole of the latching part 25 and positioning it in the latching hole 26 extending upward, using the header part 20, While increasing the display effect, the packaging container 10 containing the product B can be easily hooked.
[0021]
Tongue pieces 31 and 31 are formed by extending the sides 14 and 15 located on both sides of the header portion 20 as base ends. The tongue portions 31 and 31 are bent inward from the side of the header portion 20 along the sides 14 and 15, thereby forming an inner lid as shown in FIG. ing.
In this case, the tongue pieces 31 and 31 have notches 33a and 33a formed at the corners on the front end side of the tongue piece main bodies 32 and 32, respectively.
In this embodiment, the extended lengths of the tongue pieces 31 and 31 are, for example, such that the tip portions 33 and 33 are in contact with each other as shown in FIG.
[0022]
As shown in FIG. 4, the side 16 facing the side 13 where the header portion 20 is formed forms an integral extension 41 to form a lid 40. The lid 40 is the outermost lid that closes the opening 12 of the main body 11.
In particular, in the lid body 40, the distal end of the extension portion 41 is bent at a bent portion 42 parallel to the side 16 to be an extended end portion 43 facing downward, and the extended end portion 43 is formed from the opening 12. , And extended so as to be accommodated in the main body 11. In this case, the extended length from the side 16 of the extension portion 41 to the bent portion 42 is formed so as to substantially coincide with the side 14 and the side 15.
In addition, each above-mentioned bending part is shape | molded so that it may bend reliably in each bending part by pressing etc., when forming the shape shown in FIG. 3 by stamping etc.
[0023]
FIG. 6 shows the first packing member 50 provided separately from the main body 11 (separate from the sheet body). The first packing member 50 is a packing member located above the product B in the main body 11 as shown in FIG.
The outer shape of the first packing member 50 is slightly smaller than the opening 12 of the main body 11, and the outer periphery of each side 51, 51, 51, 51 has a size that is closely inscribed in the main body 11. Has been. Each side 51, 51, 51, 51 is formed with a tongue piece-like contact piece 52, 52, 52, 52 that contacts the inner wall of the main body 11, and extends toward the opening 12. The packing member 50 has a concave shape.
[0024]
Here, the packing member 50 is formed by cutting out the four corners of one sheet into a square shape and bending each piece 51 to form each contact piece 52, but the packing member 50 is formed so as to form each contact piece 52. The member 50 may be formed in a concave shape in advance, and the packing member 50 is not concave, and at least the contact piece 52 on the header portion 20 side may extend to the header portion 20 side.
Further, a hole 53 is formed at the center of the horizontal tray-like portion 56 of the first packing member 50. In this embodiment, the hole 53 is a through hole, and the tip of the head portion H such as a hood portion that covers the nipple N of the product B can be inserted therethrough. As a result, the hole 53 comes into close contact with the upper portion of the head portion H, so that the position of the product B is regulated so as not to move in the main body 11 in the state shown in FIG. Of course, this through hole may be formed in a recess corresponding to the shape of the product B.
[0025]
FIG. 7 is a schematic sectional view taken along line AA in FIG.
As shown in the drawing, a second packing member 55 is disposed at the bottom of the main body 11 so as to be positioned under the product B. The second packing member 55 is shaped to receive the bottom of the product B.
Both the first packing member 50 and the second packing member 55 are preferably made of transparent plastic. In this embodiment, the first packing member 50 is made of polypropylene and the second packing member 50 is made of a transparent plastic. The packing member 55 is made of softer polyethylene terephthalate.
And although not shown in figure, you may make it accommodate under the 2nd packing member 55 the instruction manual etc. which should be attached to the goods B if necessary.
[0026]
Next, a structure for closing the opening 12 in FIG. 4 in a state where the packaging container 10 accommodates the product B will be described.
In this case, with the second packing member disposed on the main body 11 and the product B accommodated thereon, the first packing member 50 of FIG. 6 is placed in the main body 11 as shown in FIG. 52 so that the product 52 extends upward so that the product B does not move in the main body 11.
And each tongue piece part 31 and 31 which forms the inner cover of FIG. 4 is bent in the position of each edge | side 14 and 15, and it folds inward so that the opening part 12 may be covered, and it is set as the state shown in FIG. This prevents foreign matter and the like from entering from both sides of the header portion 20, and foreign matter such as dust and debris enters even inside the lid 40 after closing the lid 40, which will be described later. However, since the tip portions 33 and 33 of the tongue pieces 31 and 31 are in contact with each other and there is almost no gap, foreign matter or the like is prevented from entering the product side from this position.
In this regard, in the unlikely event that foreign matter or the like enters beyond the inner lid, the tray portion 56 of the first packing member 50 can prevent this.
[0027]
Next, in FIG. 4, the second extension portion 23 of the header portion 20 is folded inward by the bent portion 22, and the inner surface of the second extension portion 23 is brought into contact with the contact piece 52 on the header portion 20 side of the packing member 50. Makes contact. That is, the header-side contact piece 52 of the packing member 50 is sandwiched between the back body 11 provided with the side 13 on the header portion 20 side and the second extension portion 23. At this time, the folded tip portion 24 of the second extension portion 23 is inserted into the main body 11 from the opening 12.
Further, the extension portion 41 constituting the lid body 40 is bent inward along the bent portion 16 so that the bent portion 42 abuts on the base end portion of the header portion 20, and at the same time, the extended end along the bent portion 42. The portion 43 is folded and the extended end portion 42 is inserted into the main body 11 from the opening 12. At this time, the outer surface of the extended end portion 43 comes into contact with the surface on the side facing the opening 12 which is the outer surface of the second extension portion 23.
[0028]
Here, both the header part 20 and the lid 40 are integrally formed of a thin polypropylene plate. For this reason, as shown in FIG. 5A, the second extension 23 of the header portion 20 repels the folding of the bent portion 22 and slightly returns to the direction of the arrow. Similarly, the extended end 43 serving as the distal end of the lid 40 is repelled by the folding of the bent portion 42 and the folded portion 16 of the bent portion 16 serving as the base of the lid 40, and is slightly in the direction of the arrow. Trying to return. In this state, as shown in FIG. 5 (b), when the lid 40 is closed and the tip 43 is brought into contact with the surface of the second extension 23, which is the folded tip of the header 20, the contact is made. The surface is urged by the force of each of the arrows described above to be surely brought into close contact. The bent portion 16 and the bent portion 42 are bent by approximately 90 degrees in this state. The folding part 22 of the header part 20 is folded by approximately 180 degrees.
[0029]
Furthermore, even if foreign matter or the like enters from the gap in the opening 12 between the lid 40 and the header 20, the inner surface of the header 20 is concave as shown in FIG. 7. Since the contact pieces 52 of the first packing member 50 are in contact with each other, the foreign matter is stopped on the upper surface of the tray-like portion 56 and the like, so that the product B inside thereof is kept clean.
When the lid 40 is closed, the engaging portions 34 provided on the tongue pieces 31 and 31 enter the slits 44 and 44 provided at both ends of the bent portion 42, and the lid 40 is inadvertently opened. Is prevented.
[0030]
Thus, in the state where the lid 40 is closed as shown in FIG. 1, the contact surfaces of the distal end portion 43 of the lid 40 and the second extension 23 of the header portion 20 are tightly closed. Therefore, foreign matter such as dust and dirt from the outside can be extremely effectively prevented from entering the inside of the lid body 40, and in the event of intrusion, the packing member 50 is isolated from the product B. , That intrusion can be stopped.
Here, preferably, the bending guide portion 13a is provided by pressing or bending in advance along the side 13 provided with the header portion 20 as shown in FIG. For this reason, as shown in FIG. 2, when the latching portion 25 of the packaging container 10 is latched by the latching hook 61 or the like, when the packaging container 10 is suspended, FIG. As shown in FIG. 6, the header portion 20 as a whole is bent at the position of the bending guide portion 13a on the side opposite to the opening portion 12, so that an unreasonable force is applied to the header portion 20 on the lower side of the latch portion 25, and the lid The vicinity of the latching portion 25 at the contact surface between the extension end 43 of the body 40 and the second extension 23 of the header portion 20 is not opened, and the extension end 43 and the second extension 23 are reliably connected. It is possible to maintain the contact and effectively prevent foreign matter and the like from entering the main body.
[0031]
The packaging container 10 of the present embodiment is configured as described above, and is formed of a thin plastic as a whole. Therefore, the packaging container 10 can be easily formed transparently, and the external shape of the product B in the main body 11 can be easily seen. Since it is easy for a person considering purchase to evaluate the product B without taking the product B in his / her hand, it is easy to draw attention at the time of purchase.
Further, since the whole is formed of a thin plastic, not only is it easy to form it transparently, but even if printing with color is performed, the color is good, and by performing predetermined printing, the color can be applied to the main body 11. Etc., and can be formed so transparent that the outer shape of the product B can be visually recognized. For this reason, it can be set as the packaging container 10 which exhibits a more attractive appearance.
[0032]
In addition, as described above, due to the unique structure of the lid 40, the header portion 20, and the packing member 50, foreign matter such as dust and dirt from the outside can be extremely effectively prevented from entering inside the lid 40. As a result, the product B can be stored cleanly and, together with the transparent structure of the main body 11, the person considering the purchase can observe the clean product B from the outside, contributing to the appeal of the product. Can do.
[0033]
