Description

  The present invention prevents the occurrence of defects such as cracks, cracks, breakage, etc. in the articles contained in the container or the container itself when the article container accommodated in the box is subjected to an impact caused by dropping or the like. It relates to the cushioning material.

Conventionally, various lifestyle-related items such as cosmetics and office supplies are sold in a single box (box) made of paper or synthetic resin. This box is or facilitate loading and unloading of goods, in order or a margin to put an article such instructions with articles, which is slightly larger design than the article to be accommodated.

  However, due to the fact that the box is designed to be large as described above, there is a problem that the article swings inside the box due to vibration and impact during the transportation of the article and the contents are damaged. It became. In other words, if the article is a solid cosmetic such as a cosmetic foundation or eye shadow, the solid cosmetic may crack or crack due to vibration or impact during transportation, resulting in a defective product leading to consumer complaints. There is.

Thus, the box-shaped flap is used to protect the solid cosmetic container (compact) inside (see, for example, Patent Document 1), or a protective case is produced by matching the shape of the solid cosmetic container to the container. For example, a case where a solid cosmetic is protected by giving the case a shape having a cushioning property or accommodation property (see, for example, Patent Document 2) is performed.
In addition, a solid cosmetic container itself is also provided with a buffer mechanism (see, for example, Patent Document 2 and Patent Document 3) .
Japanese Patent Laid-Open No. 08-301269 (FIGS. 1 and 3) JP 2005-185356 A (FIGS. 1-5, paragraphs [0012]-[0015], paragraphs 8, 9, 14, 15) JP 2006-55204 A (FIG. 1)

However, in the packaging box shown in Patent Document 1, the solid cosmetic container may be a substantially square shape similar to the packaging box. However, in the substantially circular cosmetic container, the flap cannot sufficiently protect the solid cosmetic container and is effective. Can not be pulled out. Further, when a protective case as shown in Patent Document 2 is manufactured, the effect is great in terms of protecting the solid cosmetic, but the manufacturing cost is increased. Also Allowing the buffering mechanism in a solid cosmetic container itself represented by a solid cosmetic container and Patent Document 3 of the same document, or a complicated container itself, or resulting increase in the number of components is further for Patent Document 3 There was a point that it was weak against the impact from the side.
Therefore, the present invention provides various life-related articles contained in a box, in particular, a container for solid cosmetics that is vulnerable to vibrations and shocks. It is an object of the present invention to provide a cushioning material that can weaken the impact.

  In order to achieve the above object, as a result of intensive research by the present inventors, a thin plate-shaped cushioning material sheet is assembled in a container and accommodated in a box, thereby reducing the cost with a simple structure and from the outside. The present invention has been completed by finding that it has a great effect of reducing the impact, particularly the impact from the lateral direction.

Each of the present invention is a container having a container main body having an article accommodating recess inside and a lid for closing the container main body whose upper surface is opened, and a box having at least a container accommodating part for accommodating the container. It is a thin plate-like cushioning material sheet that is assembled to a container and accommodated in a box, and the cushioning material sheet is opposed to each other between the containers around the cushioning material sheet, and from the container body It is assumed that the cushioning material sheet has both sides protruding and can be assembled to the container so as to be sandwiched between the container body and the lid. When the cushioning sheet is assembled to the container so as to be sandwiched between the container body and the lid, the position of the cushioning sheet is stable and preferable. The form of the container lid may be such that the container body and the lid part are screwed together, or the container body and the lid part may be connected via a hinge part.
The cushioning material sheet according to the present invention is based on the above-described premise configuration, and in the state where the cushioning material sheet is assembled to the container so as to be sandwiched between the container body and the lid portion, Both sides facing each other with the container in between are in contact with the side surface of the container housing portion of the box.
The cushioning material sheet according to the present invention is based on the above-described premise configuration, and the distance between both sides of the cushioning material sheet facing each other with the container interposed therebetween is the distance inside the side surface of the container housing portion of the box. It is characterized by being in the range of 80% or more.
In the cushioning material sheet according to the present invention, the overall shape of the cushioning material sheet seen through the top surface of the container in a state where the cushioning material sheet is assembled to the container and accommodated in the box, It is preferable from the viewpoint of the buffering effect that they are substantially the same.
The cushioning material sheet according to the present invention is composed of a single cushioning material sheet, and it is preferable that the cushioning material sheet has a substantially quadrangular shape, which simplifies the construction and is a commonly used box. Although it is the same as the shape of a body and preferable, for example, a substantially circular shape, a substantially oval shape, a pentagonal shape (see FIG. 4), a polygonal shape, an octagonal shape (see FIG. 5), a cross shape (see FIG. 6), a house shape ( (See FIG. 7).
The cushioning material sheet according to the present invention preferably has a flap on the cushioning material sheet. This flap is effective for increasing the cushioning effect, and the flap is effective when installed on at least one opposite side of the cushioning material sheet. If the cushioning material sheet has a substantially rectangular shape, it is more preferable to provide flaps on its four sides.
The overall shape of the container seen through from the upper surface side of the container in a state where the buffer material sheet is assembled in the container and is accommodated in the box is not substantially rectangular, for example, substantially circular, substantially elliptical, pentagonal, polygonal Even in such a shape, the effect is sufficiently exhibited in the present invention.
The cushioning material sheet according to the present invention may be capable of changing the relative position of the cushioning material sheet with respect to the container after the cushioning material sheet is assembled to the container. The cushioning material sheet is accommodated in the box after being assembled in the container. However, when a logo or the like is printed on the container, there is a case where it is desired to determine the position of the cushioning sheet with respect to the box. At that time, if the position of the cushioning sheet relative to the container can be easily changed, the position of the sheet, the container, and the box can be easily adjusted, which is extremely convenient.

Therefore, it is possible to prevent the quality deterioration of the contents due to vibration.

  Next, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment of the present invention. In this embodiment, a cosmetic container is used as the container. As is clear from FIG. 1, the cushioning material sheet 1 of the present invention is assembled to the container 2 and accommodated in the box 3. The cushioning material sheet 1 has a shape seen through from the upper surface side of the container 2 is substantially the same shape (square) as the shape of the box 3, and its size is designed to be slightly smaller than the box, but is substantially the same. It is a size. In this figure, the box 3 is composed only of the container accommodating portion 3a for accommodating the container, but it is intended to improve the product appeal from the surface opposite to the surface where the flap portion 3b of the box is connected. The display part which printed the logo and tagline etc. which were made may be connected continuously, and the hanging piece which provided the hole for hanging a box is erected from the flap part 3b base of a box Any other mechanism may be employed.

  FIG. 2 is a cross-sectional view taken along the line AA ′ of FIG. And a lid portion 2b for closing. Inside the container, a puff 6 for applying cosmetics on a metal plate 5 containing cosmetics 4 is accommodated. The cushioning material sheet 1 of the present invention is assembled between the container body 2a and the lid 2b.

FIG. 3 shows how to assemble the cushioning material sheet 1 in the present embodiment. In this example, the cushioning material sheet 1 is provided with a cushioning material sheet main body 1a and a through hole 1b at the center thereof. The through-hole 1b is designed so that the container main body neck 2d screwed with the lid 2b of the container 2 can be inserted and the container main body shoulder 2e cannot be inserted. It is placed on the body shoulder 2e. The cushioning material sheet 1 is assembled to the container 2 by screwing the lid 2b from above in the state. The method of assembling the cushioning material sheet is not limited to this method. For example, a groove is formed in the outer periphery of the container body 2a or the outer periphery of the lid 2b , and the through hole 1b of the cushioning material sheet is forcibly fitted therein. Also good.

  In the operation of accommodating the container 2 in which the cushioning material sheet 1 is assembled in this manner in the box 3, the cushioning material is compared with the box that was originally designed to be larger than the container in consideration of the capacity of the container. Since the size of the sheet 1 is substantially the same size slightly smaller than that of the box 3, it is expected that the accommodating operation becomes difficult. However, since the cushioning material sheet 1 is manufactured in substantially the same shape as the box 3, it serves as a guide when the container 2 is accommodated, and the accommodating operation is not difficult.

  1 and 2, the cushioning material sheet 1 is manufactured from a single sheet. However, the cushioning material sheet 1 may be divided into two or three parts according to the structure of the container 2 and may have the same configuration. However, since it is inevitable that the work of assembling becomes complicated due to the increase in the number of parts, it is composed of one sheet as much as possible, the assembling work surface, the number of parts reduction, the production cost Can be said to be desirable.

In the form of the present invention, the box 3 has a quadrangular shape, and the cushioning material sheet 1 has a quadrangular shape accordingly. However, the present invention is not limited to this, and for example, the shape of the box 3 viewed from the upper surface side of the container is used. It may be a polygonal shape (see FIG. 4) or a shape having a dent. Furthermore, the cushioning material sheet 1 does not necessarily have the same shape as the box 1 and may have a different shape. For example, a cushioning material sheet having an octagonal shape (see FIG. 5), a cross shape (see FIG. 6), a house shape (see FIG. 7), or the like may be used in a rectangular box. What is necessary is just to take the structure which fixes the position of the container in a box with a buffer material sheet, and reaches | attains a container via a buffer material sheet with respect to the impact from a box side surface direction. Naturally, if it becomes a special shape, it becomes a factor of cost increase and the accommodation work may be complicated, so the container accommodation portion 3a of the box 3 and the cushioning material sheet main body portion 1a have the same rectangular shape, and slightly It is desirable that the cushioning material sheets are smaller and have substantially the same size.

  In the embodiment of the present invention, the container 2 has a substantially circular shape. In the cushioning material sheet of the present invention, the shape of the container is not limited to this, and the present invention can be applied to containers of various shapes such as a quadrangular shape or a polygonal shape other than a quadrangular shape, an elliptical shape, a fan shape, etc. Is possible.

  FIG. 8 and FIG. 9 show another embodiment of the present invention, which is different in that the cushioning material sheet 1 has a flap 1c, and the rest is the same as that shown in FIG. The flap is provided so as to be connected to the side of the cushioning sheet main body 1a, and is used by being bent at the boundary between the cushioning sheet main body 1a and the flap 1c. When receiving an impact by the flap 1c, it plays a role of a cushion and can further enhance the buffering effect. The direction of folding the flap 1c may be either up or down, but it is necessary that the flap after folding does not enter the cushioning material sheet main body 1a side (the bending angle does not become 90 degrees or more). This is because the flap cushioning effect cannot be obtained if it is bent too much. Even if the flap 1c is provided on only one side of the cushioning sheet main body portion 1a, the effect is exhibited. In FIG. 8 or FIG. 9, flaps 1c are provided at two locations. Moreover, if the buffer material sheet 1 has a substantially square shape, it is more preferable that the flaps 1c are provided on all four sides.

FIG. 10 shows still another embodiment of the present invention, which is a container of the type in which the container main body 2a and the lid part 2b of the container 2 are connected via a hinge part 2f. Even in such a type of container 2, the cushioning material sheet 1 of the present invention is effective, and the cushioning material sheet 1 may be placed on the container body 2a as shown in the figure and sandwiched between the lids 2b. In the case of FIG. 10, as shown in FIGS. 1 to 3, 8, and 9, since the container body neck 2 d does not exist, the through hole 1 b is unnecessary, but when the lid 2 b of the container 2 is closed. In order to avoid contact with the hinge portion 2f, the cushioning material sheet 1 is provided with a relief portion 1d .

  In addition, about the form of the cover part 2b, although the example connected with the container main body 2a through a type and a hinge was shown, this invention is not restricted to this, The internal diameter of the cover part 2b and the container main body neck part The size of 3d may be tightly fitted, or a groove may be provided around one of the lid 2b and the container body 2a, and a boss may be erected on the other to be closed. It is possible to correspond to a closed type of type.

FIG. 11 is a view showing a state in which the cushioning material sheet 1 is placed on the container body 2a, and a partially enlarged view is attached. Here, the container body shoulder 2e has a positioning protrusion 2g, and the cushioning material sheet 1 corresponding to the positioning protrusion 2g is also provided with a positioning recess 1e. Thereby, relative positioning of the container main body 2a and the buffer material sheet 1 is made. Usually, in order to lead the container body 2a and the lid portion 2b or has become as the relative position is determined by the design of the engagement portion, provided with a mechanism for determining the aggressive relative position to as FIG. 11 Thus, the relative position between the lid 2b and the cushioning material sheet is also determined. Thereby or have been subjected to design design, for example, the lid portion 2b, in the case of lead and logo marked, and the lid portion 2b of the cushioning material sheet 1 and the box 3 and the container 2 when working to accommodate the box body It is possible to save the trouble of aligning.

  However, providing such a positioning mechanism naturally increases the cost. Normally, in the container of the type in which the lid portion 2b is screwed as shown in FIG. 8 or FIG. 1, a slight gap is generated between the container main body shoulder portion 2e and the lid portion 2b in order to avoid problems such as rubbing and cracking. Designed. By adjusting the thickness of the gap and the cushioning material sheet 1, the cushioning material sheet 1 can be rotated relative to the container 2 even after the lid is closed. It can be accommodated.

In FIG. 12, the container body 2a and the cushioning material sheet 1 are relatively positioned by a method different from that in FIG. The recess of the container body 2a when closing the lid portion 2b in this embodiment, the projecting portion of the lid portion 2b is inserted, by utilizing the concave portion of the container main body 2a, can be inserted into the recess in the cushioning material sheet 1 The insertion piece 1f is erected. This and the relief part 1d can determine the relative positions of the container body 2a and the cushioning material sheet 1. Furthermore, this can also have the function to maintain the fixed state of the buffer material sheet 1 and the container 2 firmly.
11 and 12, providing a positioning mechanism for the cushioning material sheet 1 and the container 2 is very useful in terms of accommodation work in the box 3 and design as a product.

  The material of the cushioning material sheet 1 in the present invention can be selected from materials generally used for packaging materials as long as it has an appropriate strength and elasticity, and can be manufactured into a thin plate shape. Polyester resin (polyethylene terephthalate) (PET), polybutylene terephthalate (PBT, etc.), polyolefin resins (polyethylene (PE), polypropylene (PP), etc.), acrylic resins (polymethyl methacrylate (PMMA), etc.) and polystyrene resins (PS), etc. Or paper such as cardboard can be used. Among these, polyethylene terephthalate is preferable from the viewpoint of strength, elasticity, and cost.

  The thickness of the cushioning material sheet 1 in the present invention can take various ranges depending on the size and weight of the article to be accommodated. Taking the cosmetic shown in FIG. 1 as an example, the box is a rectangular parallelepiped of about 70 × 70 × 24 mm made of PET, and the cosmetic container is made of acrylonitrile styrene (AS) and has a size of about φ65 × 23 mm. If so, the buffer material sheet 1 made of PET can take a thickness of about 0.1 to 1 mm. If it is this range, it is excellent in terms of strength / elastic force as a buffer material and material cost.

The size of the flap 1c of the cushioning material sheet 1 is also arbitrary. For example, in FIG. 8, the length of the flap is shorter than the length of one side of the cushioning material sheet, but it can be accommodated in the box 3. If there is, the length beyond the side of the cushioning material sheet 1 may be used. Further, the width of the flap 1c is preferably 3 mm or more, more preferably 5 mm or more in consideration of the bendability and the cushioning property upon impact. The maximum width of the flap 1c is such that the flap 1c comes into contact with the bottom surface or the top surface when the cushioning sheet 1 is assembled to the container 2 and the boundary between the cushioning sheet main body 1a and the flap 1c is bent at a right angle. If it is within the range, the flap 1c does not float the container 2 in the box 3 or pushes it up and down, so it is desirable to set within this range.

In expressions herein, there is a container holder of the box and the overall shape of the cushioning material sheet is substantially the same, the external shape of the cushioning material sheet cushioning material sheet main body portion 1a and here This means that shapes such as flaps and penetrations are not included. Furthermore , the meaning that the shape is substantially the same is that the outline of the outer shape is the same even if chamfering or R processing is added to the corner of the cushioning material sheet, or a recess is partially provided. If there are, they are assumed to have the same shape.

Similarly, in the expression in the present specification, the buffer material sheet is also the same in that the buffer material sheet is slightly smaller and substantially the same size with respect to the size of the container housing portion of the box and the buffer material sheet. It means the size of the outer dimension of the main body part 1a , and the meaning of substantially the same is expressed by the length of the side, and the size of the side of the cushioning material sheet corresponding to the side of the box is This refers to a case where the size is 80% or more of the side dimension, preferably 90% or more, and more preferably 95% or more.

Next, examples of the present invention and comparative examples will be given, and the effects of the present invention will be described by performing a drop test.
The cosmetic material having the formulation shown in Table 1 is cast (solidified) into a known metal pan, and fixed to the bottom of the article-receiving recess of the cosmetic container shown in Table 2 with a commercially available double-sided tape. About the Example with which the sheet | seat and the cover part were mounted | worn, and the comparative example without a buffer material sheet | seat, it dropped freely perpendicularly to the side surface direction from the height of 200 mm, and observed the frequency | count until breakage of the solidified cosmetics occurred. . The results are shown in Table 3. As shown in FIG. 13, the details of the direction of dropping are the X direction for the left-right direction of the box (the side without the flap of the box), and the Y direction for the up-down direction of the box (the side with the flap of the box). did.

As is clear from the results of Table 3, as in Comparative Example 1, without the cushioning material sheet, the cushioning material cannot withstand five drops in the X direction and cannot withstand ten drops in the Y direction. By installing the sheet, the impact resistance is remarkably improved (17 times or more). Moreover, it was confirmed that the effect was further improved by providing a flap on the cushioning material sheet (it is possible to withstand a drop of 50 times or more). The reason why the test result in the Y direction is better than that in the X direction is due to the cushion effect of the flap of the box.

There are various types of articles to which the cushioning material sheet of the present invention can be applied. In addition to the cosmetics shown in the embodiment, it can be used in office equipment such as daily necessities, precision equipment, stationery, etc. Any material can be used as long as the impact can be transmitted to the article via the material sheet. It is an invention that can be widely used in industry.
