Description

Technical Field

[0001] The present invention relates to a replacement core set, which comprises: a replacement core packaging body capable of accommodating a large amount of replacement cores of writing tools; and a replacement core box capable of accommodating replacement cores divided into small portions from the packaging body. Background Art

[0002] For example, refills for mechanical pencils are provided in units of several dozen pieces housed in a thin and elongated resin refill box. When a user of the refills runs out of refills, the user disposes of the resin refill box.

[0003] However, in recent years, the issue of microplastics flowing into the ocean has attracted attention, and the momentum for solving global environmental problems, such as controlling the use of plastics that are primarily disposable, has been growing.

[0004] Therefore, for the purpose of environmental protection, several proposals have been made regarding replacement core boxes using paper as a raw material.

[0005] Patent Document 1 discloses a replaceable core box in which a disc-shaped bottom plate is mounted on the lower end of a cylindrical body made of paper material, and a cylindrical cover body made of paper material having a top plate is rotatably mounted on the upper portion of the cylindrical body.

[0006] According to this replacement core box, by aligning the notch formed on the cylindrical body side with the notch formed on the top plate of the cover body, the replacement core accommodated in the cylindrical body can be taken out through the notch.

[0007] Patent Document 2 discloses a replacement core box in which a middle box for storing a replacement core is inserted into an outer box so as to be movable up and down, and a lid that is opened and closed by rotation is formed at the upper end of the middle box.

[0008] In the replacement core box, a tongue piece that is locked with a part of the outer box is provided at the upper end of the cover that is opened and closed by rotation, and the cover is opened by utilizing the locking action of the tongue piece with respect to the outer box generated as the middle box rises. In addition, the outer box and the middle box are respectively formed by bending paper materials.

[0009] Patent Document 3 discloses a refill container including a paper rectangular tube-shaped inner box that accommodates a refill and a paper rectangular tube-shaped outer box that covers the inner box.

[0010] A core removal port is formed at a corner of the top surface panel of the inner box, and a hinged opening and closing portion that can cover the top surface panel of the inner box is formed on the outer box. Therefore, by opening the hinged opening and closing portion, a replacement core can be taken out from the core removal port of the inner box.

[0015] Patent Document 3: Japanese Patent Application Laid-Open No. 11-180090 Summary of the invention

[0016] Problem that the invention aims to solve

[0017] The replacement core boxes made of paper are each constructed by combining two or more components such as an inner box and an outer box. In order to mass-produce these replacement core boxes, automatic equipment is required to bend and shape the paper raw materials that become the inner box and the outer box. Therefore, it is inevitable to increase the manufacturing cost of the replacement core boxes.

[0018] In addition, the replacement cores for mechanical pencils are provided in units of several dozen (e.g., 40) in a replacement core box, and when the replacement cores are used up, the replacement core box is also discarded. Therefore, the replacement core box is discarded without achieving a sufficient actual utilization effect corresponding to the manufacturing cost of the replacement core box.

[0019] The present invention is made with regard to the above-mentioned actual situation, and intends to use so-called corrugated paper to form a replacement core packaging body that can accommodate a relatively large number of replacement cores for writing tools, so as to help reduce the amount of plastic material, and to be able to transfer one or more replacement cores taken out from the replacement core packaging body in small portions into a replacement core box for use.

[0020] Therefore, an object of the present invention is to provide a refill package and a refill set for a writing instrument that achieves plastic elimination and suppresses an increase in manufacturing costs.

[0021] Solutions for solving problems

[0022] The replacement core packaging body for writing instruments of the present invention, which is made to solve the above-mentioned problem, is characterized in that the replacement core packaging body is composed of a flat plate body formed by corrugated paper, and the flat plate body has a central core formed into a wavy shape by a paper substrate and a lining board formed by a paper substrate and adhered to both sides of the central core, and a linear space portion formed between the central core and the lining board is set as a replacement core storage chamber, and replacement cores of writing instruments are stored in the replacement core storage chamber.

[0023] In this case, it is desirable that a replacement core removal opening of the replacement core storage chamber is formed at an end portion of the flat body, and a sealing label covering the replacement core removal opening is attached to the flat body.

[0024] Moreover, it is preferred that a replacement core storage chamber which serves as an empty chamber and does not store replacement cores is set in a part of the replacement core storage chamber, and the replacement cores are grouped into a plurality of replacement cores divided into small portions and are intermittently stored in the replacement core storage chamber except for the replacement core storage chamber which serves as the empty chamber.

[0025] Furthermore, in the flat body, the compression sealing portion is applied in a direction perpendicular to the surface of the flat body, thereby closing one side of the linear space portion forming the replacement core storage chamber.

[0026] On the other hand, a replacement core for a writing instrument of the present invention is provided in the form of a replacement core package for a writing instrument and a replacement core box capable of storing one or more replacement cores taken out from the replacement core package for the writing instrument.

[0027] Effects of the Invention

[0028] The replacement core packaging body of the writing tool of the present invention is composed of a flat plate body formed of corrugated paper, and the flat plate body is formed by pasting lining boards on both sides of a core formed in a corrugated shape. In addition, a linear space formed between the core and the lining board is set as a replacement core storage chamber, and the replacement core of the writing tool is stored in the replacement core storage chamber.

[0029] Therefore, a certain amount of replacement cores taken out from the replacement core package can be reloaded into the existing replacement core box for reuse. Therefore, even if the replacement core box for storing the replacement cores divided into small portions is formed of resin raw materials, it can be continuously used instead of being used once.

[0030] In addition, even if the replacement core box is not provided, the same effect can be obtained by obtaining a replacement core set including the replacement core package and the replacement core box. Thus, a replacement core package and a replacement core set for a writing instrument can be provided that can achieve plastic removal and suppress an increase in manufacturing costs.

[0039] The refill package and refill set for a writing instrument of the present invention will be described based on the illustrated embodiments.

[0040] first, Figure 1 to Figure 6 Indicates a replacement core package for a writing instrument, Figure 1 and Figure 2 The overall appearance structure of the replacement core package is shown. The replacement core package 1 is composed of a flat plate 2 formed by forming corrugated paper, which is made of paper, into a rectangular shape.

[0041] Examples of the components constituting the flat plate body 2 formed of the corrugated paper are as follows: Figure 3 As shown, Figure 3 As shown in FIG. 2 (A), the flat body 2 includes a core 3 formed into a corrugated shape by a paper base material, and a front liner 4 and a back liner 5 formed by a paper base material and arranged on both sides of the core 3 .

[0042] And, if Figure 3As shown in (B), the front lining board 4 and the back lining board 5 are attached to each other with the core 3 as the center, thereby forming a flat body 2 from double-sided corrugated paper. Figure 3 As shown in (C), near one end (upper end) of the flat body 2, a compression sealing portion 6 is formed in a direction transverse to the wavy pattern applied to the core 3, and the compression sealing portion 6 is formed in a straight line in a state where the flat body 2 is compressed from both the front and back surfaces of the flat body 2 to make it concave.

[0043] During the forming process of the compressed sealing portion 6, by staggering the positions of the concave and convex teeth of one of the upper and lower opposing jigs used to form the compressed sealing portion 6 and the concave and convex teeth of the other jig in a straight line direction, that is, arranging them in a manner in which the concave and convex are opposite to each other, the concave and convex marks can be effectively given in the front and back directions along the length direction of the compressed sealing portion 6.

[0044] As a result, the front liner 4 and the back liner 5 with the core 3 at the center are unlikely to be separated, and the shape of the compressed sealing portion 6 can be maintained for a long period of time.

[0045] The compression and sealing portion 6 seals one side (upper portion) of each replacement core storage chamber 8 formed by a plurality of linear space portions formed in parallel to each other, which will be described later.

[0046] A circular hanging hole 7 is formed through the compression seal portion 6 at the upper center thereof. The hanging hole 7 is used to hang the replacement core package 1 on a product hanging rod when the replacement core package 1 is displayed and sold in a stationery store or the like.

[0047] In addition, the compression sealing portion 6 and the hanging hole 7 can be formed and processed simultaneously with respect to the flat plate body 2 .

[0048] Figure 4 and Figure 5 The following shows an example of a state in which replacement cores are stored in a replacement core storage chamber formed in the flat body 2 formed of the corrugated paper and a preferred arrangement state of the replacement cores stored in the replacement core storage chamber.

[0049] In this embodiment, the linear space portion formed between the corrugated center core 3 and the front lining plate 4 and the back lining plate 5 is used as the replacement core storage chamber 8 .

[0050] That is, when the replacement core package 1 is suspended by the suspension hole 7, a plurality of linear space portions arranged in the vertical direction from the compression sealing portion 6 to the lower side become the replacement core storage chamber 8 (see Figure 5 (B)).

[0051] Furthermore, the lower end portion of the flat plate body 2 in the hanging replacement core package body 1 serves as a replacement core removal port 9 that also serves as an insertion port for the replacement core L.

[0052] In the embodiment of the replacement core package 1, a replacement core storage chamber as an empty chamber in which no replacement core L is stored is set in a part of the replacement core storage chamber 8, and the replacement core L is a group of replacement cores for a plurality of mechanical pencils (for example, 40 pieces) divided into small portions, and is intermittently stored in the replacement core storage chamber 8 (see Figure 5 ).

[0053] In the example shown in the figure, one replacement core package 1 contains four sets of replacement cores L (see Figure 4 ).

[0054] return Figure 1 A sealing label 10 is attached from the front side (front lining plate 4) to the back side (back lining plate 5) of the replacement core storage chamber 8, and the replacement core removal port 9 formed at the lower end of the flat body 2 is sealed by the sealing label 10. Thus, the four sets of replacement cores L stored in the replacement core storage chamber 8 are prevented from scattering.

[0055] The sealing labels 10 correspond to the storage positions of the four sets of replacement cores L. Figure 1 The back side of the replacement core package 1 shown in (B) is formed with an uncoated wing portion 10a. Next to the wing portion 10a, a peeling portion 10b coated with glue and surrounded by an easy-tear line is formed in a rectangular strip shape. Figure 1 As shown in (A), the peeling portion 10b surrounded by the easy tear line continues to the front side of the replacement core package 1.

[0056] Therefore, the user can take out a set (40 pieces) of refills L from the refill package 1 by pinching any of the wing portions 10 a formed on the sealing label 10 and peeling off the peeling portion 10 b .

[0057] also, Figure 6 The example in which the replacement core package 1 is placed at the back side and the replacement core L of the group facing the right side is taken out is shown.

[0058] Thus, a group of replacement cores L divided into small portions from the replacement core package 1 can be reloaded into an existing replacement core box for use. Therefore, even if the replacement core box for storing the replacement cores divided into small portions is formed of a resin material, it can be continuously used without being used once.

[0059] Figure 7 and Figure 8 This example shows an example in which the replacement core package 1 and the replacement core box 11 are provided as a replacement core set, assuming that the user does not have the replacement core box.

[0060] The replacement core box 11 shown in this example can accommodate a group of replacement cores L (40 pieces) divided into small portions from the replacement core package 1, and Figure 7 As shown, the width dimension W1 of the replacement core storage opening formed in the replacement core box 11 is set to be wider than the width dimension W2 of the entire group of replacement cores L divided into small portions and stored in the replacement core package 1 (W1>W2).

[0061] The box body 11b on the back side of the replacement core box 11 is mounted on the cover member 11a so as to be slidable forward relative to the cover member 11a. When the box body 11b is slid forward, the front end of the box body 11b is deformed so as to bend toward the back side and the replacement core storage port is opened.

[0062] According to the replacement core group, Figure 7 As shown, the replacement core box 11 is located obliquely below the replacement core package 1, and the replacement core L is slid from the replacement core package 1 to the replacement core box 11 side and injected into the replacement core storage port in the open state, so that a group of replacement cores L can be smoothly transferred to the replacement core box 11 side.

[0063] In addition, regarding the replacement core box 11, the present applicant has previously applied for it, which is disclosed as Japanese Patent Application Laid-Open No. 2022-96637.

[0064] As can be seen from the above description, the replacement core package and replacement core set of the writing instrument according to the present invention can achieve the effects described in the effect column of the invention, such as being able to achieve deplasticization and suppress the increase in manufacturing costs.

[0065] Furthermore, in the above-described embodiment, the replacement core package 1 is described based on an example of storing replacement cores for a mechanical pencil. However, the replacement core package of the present invention is not limited to replacement cores for mechanical pencils, and can also achieve the same effects by storing replacement cores for ballpoint pens (ballpoint pen refills).

[0066] Industrial Applicability

[0067] As described above, the refill package and refill set for writing instruments of the present invention are useful as a countermeasure to global environmental problems (promoting deplasticization).
