Description

  The present invention relates to a packaging material and a package in which an article is packaged with the packaging material.

  At the sales floor, products are displayed on a display fixture. When the displayed product is a textile product such as spats, in order to confirm the stretch of the fabric / knitted fabric, the consumer should face the side opposite to the display pin of the fixture with the product hung on the fixture. May pull the product. In addition, at the sales floor, products are not hung on display pins, but are sometimes placed on a display stand called a flat stand so as to lie down. Even in that case, the consumer may hold the packaging material with one hand, hold the product packaged in the packaging material with the other hand, and pull the product in the direction opposite to the packaging material. At that time, if the packaging material is made of paper, the packaging material may not be able to withstand the pulling force and may be torn. In order to improve this, conventionally, various techniques for reinforcing packaging materials have been proposed. For example, Patent Document 1 discloses a packaging material in which a hook portion for hanging a product on a fixture is folded back to be doubled to reinforce the strength.

Utility Model Registration No. 3081866 (issued on November 22, 2001)

  However, the above-described technique increases the strength of the packaging material, but doubles the hook portion, which increases the area of paper required for manufacturing the packaging material. For this reason, there is a problem that the number of packaging materials that can be taken from a certain size of paper is reduced, and the cost of the packaging materials is increased.

  Hereinafter, an embodiment of the packaging material according to the present invention will be described in detail with reference to FIGS. 1 and 2. FIG. 1 is an exploded view showing a schematic configuration of a packaging material 100 according to an embodiment of the present invention. In this figure, a solid line indicates a cutting line, and a broken line indicates a folding line. In the present embodiment, for convenience, in the packaging material 100 after assembly, the direction in which the hook insertion opening 13 is located will be described as “upper”, and the direction in which the opening 12 is located will be described as “lower”. After the packaging material 100 is assembled, the packaging material 100 is folded at a folding line T1 shown in FIG. Therefore, with the fold line T1 and the cutting lines V1 and V2 as a boundary, the hooking surface 10, the material front surface 20, the material rear surface 30, the gusset portion 40, and the insertion piece 50 in FIG. Different. That is, after assembling the packaging material 100, only the hooking surface 10 is reversed in the vertical direction on the paper surface in FIG. 1 and the “upper” and “lower” directions in the present embodiment.

  In the present embodiment, the article B is a spat with a short length, but is not limited thereto. In addition to leg wear such as socks, tights, leggings, and trousers, the article B may be other clothing such as a skirt, underwear, stomachband, neck warmer, and shirt (underwear). Moreover, a fixture is demonstrated as a display pin extending | stretching in a horizontal linear form.

  The packaging material 100 is a packaging material for the article B that can be hung on a display pin for hanging and displaying the article B. The packaging material 100 is made of paper. As illustrated in FIG. 1, the packaging material 100 includes a hooking surface 10, a material front surface 20, a material rear surface 30, a gusset portion 40, and an insertion piece 50.

  The material front surface 20 covers at least a part of the front surface of the article B in the assembled state in which the packaging material 100 is assembled. The material front surface 20 is a substantially rectangular plate-like member having a size display portion 21 where the size of the article B is printed. A hooking surface 10 to be described later is adjacent to the upper side of the material front surface 20 via a fold line T1.

  The material front surface 20 has a hanging portion that can be hung on a display pin (hanging pin). That is, the hook insertion port 13 is provided on the fold line T1 on the upper side. In the packaging material 100, for example, in the assembled state of the packaging material 100, a hook (not shown) that can be suspended from the outside of the packaging material 100 to the display pin is inserted into the hook insertion opening 13. At this time, by providing a groove in the hook, a part of the hook can be held inside the packaging material 100, and the packaging material 100 can be suspended from the display pin using the hook. The structure is not limited to the above as long as it can be suspended from the display pin. For example, by forming the shape of the packaging material 100 into a hook shape, it is possible to provide a hanging portion without requiring hook attachment. Further, the packaging material 100 is not hung on a display pin, and can be displayed by placing the product on a display stand called a so-called flat stand so as to lie down.

  The material rear surface 30 covers at least a part of the rear surface of the article B in the assembled state. It is a substantially rectangular plate-shaped member. An engagement hole 31 that engages with the insertion piece 50 is provided in the material rear surface 30.

  The gusset portion 40 secures a storage space for the article B between the material front surface 20 and the material rear surface 30 in the assembled state. Since the article B has a thickness, it is desirable that the wrapping material 100 is provided with a gusset portion 40. The gusset portion 40 is adjacent to both ends of the material front surface 20 via a fold line T3. The gusset portion 40 is formed by a fold line T3 and a fold line T4 or a fold line T5, and has a shape in which the width increases in order from the upper side to the lower side. One gusset portion 40 is adjacent to the material rear surface 30 via a fold line T4. Moreover, the other gusset part 40 is adjacent to the insertion piece 50 via the folding line T5.

(Hook surface)
The hooking surface 10 is a surface on which the article B is hooked, and is a plate-like member. An opening 12 is formed in the hooking surface 10 so as to extend along a substantially horizontal direction (predetermined direction) in a state where the packaging material 100 is suspended from the display pin. The article B is hooked on the opening 12.

(protrusion)
The protrusions 11 are provided so as to protrude along the extending direction D1 at both ends on the extending direction (predetermined direction) D1 in which the opening 12 extends. At the connection point between the hooking surface 10 and the protrusion 11, a folding line T <b> 2 (ruled line) for bending the protrusion 11 with respect to the hooking surface 10 so that the protrusion 11 extends along the gusset 40 in the assembled state. ) Is formed.

  The projection 11 is bent along the gusset 40 by bending the projection 11 about 90 degrees with respect to the hooking surface 10 along the folding line T2. The direction in which the protrusion 11 is bent may be either a mountain fold or a valley fold. Further, the protrusion 11 and the gusset 40 need not be glued.

  The shape of the protrusion 11 can be a semicircle, a trapezoid, a rectangle, a triangle, or a wave shape, but is preferably a shape having no corners, such as a semicircle. The absence of corners indicates that there is no pointed portion where the article B is caught and the outer shape is a curved surface. This is because, if there is a corner, the article B is caught and the article B is damaged, or when the article B is pulled, the load is concentrated on the article B, and the packaging material 100 is likely to be broken.

  Further, the width 11w1 of the protrusion 11 in the substantially vertical direction D2 in the state where the packaging material 100 is suspended from the display pin (the width in the direction perpendicular to the extending direction D1) is the width 12w1 of the opening 12 in the substantially vertical direction D2. The above is desirable. This is because if the width 11w1 is narrow, the strength is weakened, and the side 14 of the hooking surface 10 may be broken at a place where there is no protrusion 11.

  Further, the length 11w2 of the protruding portion 11 in the extending direction D1 is a length in which the region 41 where the protruding portion 11 is along the gusseted portion 40 in the assembled state in which the packaging material 100 is assembled fits in the gusseted portion 40. It is desirable to be. More preferably, the region 41 and the fold line T4 (fold line T5) are in contact with each other.

  When the length 11w2 of the protrusion 11 is long, the area of the development view of the packaging material 100 increases, leading to an increase in the cost of the packaging material 100. Further, when the length 11w2 of the protrusion 11 is short, the strength is weakened. Considering that the projection 11 is bent and used, it is optimal to provide the projection 11 so that the region 41 and the fold line T4 (fold line T5) are in contact with each other. In addition, in the assembly state of the packaging material 100, the area | region 41 in which the projection part 11 follows the gusset part 40 is shown with the dashed-dotted line in FIG.

  Further, the protrusion 11 functions particularly effectively when H2 is longer than H1 (when H1 <H2) as shown in FIG. This is because when H1 <H2, the strength at both ends in the extending direction D1 of the opening 12 is weakened. Here, H1 indicates the distance from the end of the opening 12 in the extending direction D1 to the side 14 of the hooking surface 10 (the end of the hooking surface 10 in the extending direction D1) in the extending direction D1. H2 indicates a distance from the lower end portion of the opening 12 in the substantially vertical direction D2 to the lower side 15 of the hooking surface 10 (the lower end portion of the hooking surface 10 in the substantially vertical direction) in the substantially vertical direction D2.

  In addition, the packaging material 100 includes a display (for example, “slightly pulling”) that prompts the woman who is the user of the article B (print P of M1 in FIG. 2) and the consumer to confirm the degree of expansion and contraction of the article. "Please see!" (Not shown) may be printed.

(Assembly method and assembly state)
A method for assembling the packaging material 100 shown in FIG. 1 will be described with reference to FIGS. FIG. 2 is a diagram showing a schematic configuration of the packaging material 100 in an assembled state. FIG. 3 is a diagram illustrating a state in which an article is packaged in the packaging material 100.

  First, the hooking surface 10 is bent downward along the folding line T1 (folding line T1 is mountain-folded). At that time, in the state before the packaging material 100 is assembled (the state shown in FIG. 1), the size display unit 21 divided by the hooking surface 10 and the cutting lines V1 and V2 is hooked when the folding line T1 is bent. Jump out of plane 10.

  Next, the material rear surface 30 is folded along the folding line T4 so as to overlap the hooking surface 10 (folding the folding line T4 is mountain-folded). At that time, the folding line T3 adjacent to the folding line T4 is also folded in a mountain. Further, the insertion piece 50 is bent along the folding line T <b> 5 so as to overlap the material rear surface 30, and the insertion piece 50 is engaged with the engagement hole 31. At that time, the folding line T3 adjacent to the folding line T5 is also folded in a mountain. In assembling the packaging material 100, the insertion piece 50 is engaged only with the engagement hole 31. In other words, the packaging material 100 is assembled only in one step of inserting the insertion piece 50 into the engagement hole 31. .

  A front view of the assembled packaging material 100 assembled as described above is shown in M1 of FIG. 2, and a bottom view (a view of the packaging material 100 from arrow A in M1 of FIG. 2) is shown in FIG. Shown in M2. As shown in M1 of FIG. 2 and M2 of FIG. 2, the hooking surface 10 is located between the material front surface 20 and the material rear surface 30 in the assembled state. Moreover, the protrusion part 11 bends with respect to the hooking surface 10 so that it may follow the gusset part 40 in an assembly state by the fold line T2. Since the protrusion 11 is not engaged with any surface and the protrusion 11 and the gusset 40 are not joined with glue or the like, the assembly process of the packaging material 100 can be reduced.

  FIG. 3 shows a state where an article is packaged in the packaging material 100. 3 is a front view showing a state in which an article is suspended from the hooking surface 10, and M4 in FIG. 3 is a front view showing a state in which the article B is packaged by the packaging material 100 (packaging body 101). FIG.

(Width of packaging material in the assembled state)
The width of the packaging material 100 in the assembled state will be described with reference to FIG. FIG. 4 is a diagram illustrating the width of the packaging material 100 in the assembled state.

  In the store, the space for furniture that can display each product is limited. Therefore, in order to increase the number of products that can be hung on a fixture as much as possible in a limited space, it is desirable to save the space necessary to display one product. Thereby, even in a limited space of the furniture, the size can be expanded, or products according to functions can be placed. In addition, by saving space for displaying products, it is possible to secure a space for placing advertisements in the furniture.

  In order to save space for displaying products, it is desirable that the width of the packaging material 100 be as narrow as possible. Therefore, as shown by N1 in FIG. 4, a simple reinforcing method that increases the length L1 from the end of the opening 12 to the side of the hooking surface 10 on the hooking surface 10 cannot be adopted. This is because the width of the packaging material 100 becomes wide, the space for displaying the products cannot be saved, and many products cannot be hung on the furniture. Therefore, the creator of the packaging material 100 provided the protrusion 11 on the hooking surface 10. N2 in FIG. 4 is a view showing the hooking surface 10 having the configuration of the protrusion 11 according to the present embodiment.

  Here, as shown by M2 in FIG. 2, in the assembled state of the packaging material 100, the protruding portion 11 is bent with respect to the hooking surface 10 along the gusset portion 40 by the fold line T2. Therefore, as shown by N2 in FIG. 4, even if the length L1 of N1 in FIG. 4 and the length L2 from the end of the opening 12 to the end of the protrusion 11 are the same, the packaging material In 100, the width of the packaging material 100 in the assembled state can be shortened. Specifically, as compared with N1 in FIG. 4, in the packaging material 100, the width of the packaging material 100 in the assembled state can be shortened by the length 11w2 of the protruding portion 11 in the extending direction D1. As a result, space saving of the packaging material 100 can be realized while reinforcing the strength of the packaging material 100.

(Cost reduction of packaging materials)
The cost reduction realized by the packaging material 100 will be described with reference to FIG. FIG. 5 is a diagram for explaining a reduction in the cost of the packaging material 100. P1 in FIG. 5 is an arrangement example of the development view of the packaging material 200 when the opening 12 is doubled to reinforce the strength, and P2 in FIG. is there.

  As indicated by P1 in FIG. 5, the packaging material 200 doubles the opening 12, so that the area of the development view is widened. Moreover, the packaging material 200 cannot arrange a developed view efficiently on one sheet of paper K1, and the margin increases. Therefore, the number of the packaging materials 200 that can be taken from the predetermined size of paper is reduced, and the cost of the packaging materials 200 is increased. Also, the amount of garbage increases, so it is not good for the environment.

  On the other hand, the packaging material 100 reinforces the strength of the packaging material 100 by the protrusions 11. Therefore, as shown in P2 of FIG. 5, the area of the development view of the packaging material 100 is smaller than the development view of the packaging material 200. Moreover, since the packaging material 100 can arrange | position an expanded view alternately on the sheet | seat K2 of a sheet | seat, a margin is reduced and the packaging material 100 can be taken from one sheet | seat K2 without waste. As a result, it is possible to suppress an increase in the cost of the packaging material 100 due to an increase in the number of the packaging material 100 that can be taken from a predetermined size of paper. As an example, with a paper having a size of 390 mm × 500 mm, two packaging materials 100 can be taken.

(Tensile test)
The fact that the strength of the packaging material 100 is reinforced by the protrusions 11 will be described below based on the tensile test results. First, the tested sample will be described with reference to FIG. FIG. 6 is a diagram illustrating a sample for a tensile test.

  The sample q1 is a package in which the article B is packaged using the packaging material 300 indicated by Q1 in FIG. 6, and the packaging material 300 is obtained by removing the protruding portion 11 of the packaging material 100. The sample q2 is a package in which the article B is packaged using the packaging material 100 indicated by Q2 in FIG. The sample q3 is a package in which the article B is packaged using the packaging material 400 indicated by Q3 in FIG. 6, and the packaging material 400 has a hanger part to which the article B is hooked, not an opening, but strips 401 and 402. It is formed by engaging. The sample q4 is a package in which the article B is packaged by using the packaging material 500 indicated by Q4 in FIG. 6, and the packaging material 500 is not related to the opening but the band-like bodies 501 and 502 are engaged. The strips 501 and 502 are doubled.

  The test results of the tensile test will be described with reference to FIGS. FIG. 7 is a diagram for explaining the test result of the tensile test. In the tensile test, the test environment was an air temperature of 20 ° C. and a humidity of 65%. Further, using a constant speed extension tensile tester, samples q1 to q4 were pulled in the vertical direction as shown in the example of R1 in FIG. 7 at a tensile speed of 100 mm / min. As a test result of the tensile test, the tensile strength (N) at the start of tearing and the tensile strength (N) at the complete break were obtained in samples q1 to q4.

  The broken portion is shown by the one-dot chain line in FIG. 6 by the tensile test. As shown in FIG. 6, in the samples q1 and q2, the hooking surface 10 was broken along the extending direction from the opening 12 to the opening 12. In the sample q3, the strip 401 was broken, and in the sample q4, the bases of the strips 501 and 502 that were not doubled were broken.

  The tensile strength (N) at the start of tearing and the tensile strength (N) at the complete break in each sample are shown in R2 of FIG. As shown by R2 in FIG. 7, the sample q2 has a tensile strength (N) of about 1.9 times higher than that of the sample q1, and the tensile strength (N) at the complete break is about 1. 7 times better. Thus, it is clear that the strength of the packaging material 100 is reinforced by providing the protrusions 11. This is probably because the tensile strength of the hooking surface 10 of FIG. 1 was increased by increasing the length from the end of the opening 12 to the side of the hooking surface 10. .

  In addition, it can be seen that the sample q2 has higher tensile strength than the samples q3 and q4, and the packaging material 100 can maintain higher strength than double the portion on which the article is hooked. It was. Furthermore, it was found that sample q2 did not begin to break to a force of about 3 kilometers. The force of about 3 kilos means that a person can apply force to break, and cannot be broken under normal use.

(Modification)
A modification of the protrusion 11 will be described based on S1 in FIG. 8 to S11 in FIG. S1 in FIG. 8 to S11 in FIG. 8 are diagrams illustrating a modified example of the protruding portion 11 of the packaging material 100.

  As shown in the protruding portion 11a of S1 in FIG. 8, the protruding portion 11 has a fold line T2 having a length similar to the length of the shorter side 14 (see FIG. 1) of the hooking surface 10. May be. Further, as shown in the protrusions 11b to 11e in S2 of FIG. 8 to the protrusions 11b to 11e of S5 in FIG.

  Further, as shown in (1) S6 in FIG. 8 and 11f and 11g in S7 in FIG. 8, the protrusion 11 is substantially square, and (2) the protrusion in S8 in FIG. 8 and S9 in FIG. 11h and the protrusion 11i may be substantially trapezoidal, and (3) may be substantially triangular as shown in the protrusions 11j and 11k of S10 in FIG. 8 and S11 in FIG.

(effect)
According to the packaging material 100, the following effects (1) to (3) can be obtained. (1) By providing the protrusions 11 protruding in the extending direction at both ends of the hooking surface 10 on the extending direction D1 in which the opening 12 extends, the strength of the packaging material 100 is reinforced and hardly broken. (2) The development of the packaging material 100 has a shape that can be disposed without waste on a sheet of paper of a predetermined size, and costs are reduced compared to double packaging materials to increase strength. The Also, it is good for the environment because it reduces garbage. (3) Since the protrusion 11 can reinforce the strength of the packaging material 100 without increasing the width of the packaging material 100, space saving in the assembled state of the packaging material 100 can be realized.
