Description

[Detailed description of the invention] [Industrial application field] The present invention allows a plurality of individual small cardboard boxes to be transported and stored together, and after transportation, the boxes can be divided into smaller pieces and sold as they are. This invention relates to a container that has unique cosmetic properties.

[Prior Art and its Problems] Various types of containers are currently known and used as packaging containers used to transport and store products, or to display products for sale. However, all of them either place emphasis on so-called logistics functions (product protection functions) such as transportation, storage, or cargo handling, or they focus mainly on the display effect of products, and are equipped with characteristics suitable for information transmission. There are many containers that are biased toward either having distribution and sales functions, and there are relatively few containers that satisfy both of the above functions at the same time. Typically, at present, products are distributed by inserting individual containers with excellent cosmetic properties inside an external container that performs a distribution function.
However, in recent years, there has been a desire for the emergence of new containers in which individual packages or inner containers based on the smallest sales unit that can be decorated with decorative printing are provided with product protection functions similar to those of outer containers. The present invention is intended to provide an outer packaging/individual packaging or an inner container as described above.

Now, referring to the requirements for the outer container, it is required that the outer container has sufficient strength required for main transportation, storage, or cargo handling, especially the rigidity and compressive strength of the container as a whole. It must have high impact resistance and handling strength. In other words, if the package itself does not have sufficient rigidity, the surface of the package may wrinkle or break when handled, and if the package does not have sufficient cushioning properties, the product may be damaged when subjected to impact. The disadvantage arises that sufficient protection cannot be achieved. On the other hand, the requirements for interior packaging or individual packaging are as follows:
It must be possible to convey product information to traders or consumers, or to perform beautiful printing necessary for promoting and advertising products, and it must also be possible to display postmarks, etc. necessary for product management. However, when trying to use paper with good printability to meet the requirements for individual packaging or interior packaging as described above, it becomes difficult to meet the strength characteristics such as impact resistance that are required for outer packaging. The current situation is that there is a trade-off between the two, and there is a need to resolve this issue.

This is also required for so-called collection and subdivision containers, which provide benefits in transportation, storage, and over-the-counter sales.

[Means for Solving the Problems] The present invention aims to attract consumer demand and cover the surface of the packaging, which is most important for conveying various information, with paperboard that can be beautifully printed, and at the same time The back side of the paperboard is lined with a cardboard sheet with a high cushioning effect, and the lid of the package is made easy to open, which is necessary for gathering and dividing. It is intended to solve problems at the same time. That is, in the present invention, a plurality of rectangular cardboard containers each having an open top are arranged with their side plates in contact with each other, and the entire opening surface of the plurality of containers is covered with a lid body having a width corresponding to the area of the container. In a transportation container that is designed to cover, the lid body is configured to include:
A lid plate made of paperboard having adhesive flaps on at least two opposing sides, and a corrugated cardboard sheet with a width covering the entire opening surface on the back side of the lid plate with an adhesive area of 10 to 80%. Attach it so that
Further, cut lines are attached to both the lid plate and the corrugated cardboard sheet, so that the container has sufficient strength to be used as a transportation container as well as to have a cosmetic effect. According to the present invention, since the surface of the container is covered with paperboard, the suitability of printing on the surface of the container is greatly improved, and it is possible to freely display postmarks and other product information that are essential for distribution and sales. The strength of the surface area is also greatly improved as the back side is lined with a corrugated cardboard sheet, and it exhibits sufficient rigidity and impact resistance to withstand cargo handling during transportation and storage.
This makes it possible to achieve the purpose of the idea.

[Embodiments] The present invention will be specifically described below based on Examples. Figure 1 shows three square cardboard containers A.
are lined up in a row perpendicular to the longitudinal direction of the container A, and are covered with a lid B that is wide enough to cover the entire opening surface of the container A, and at the same time, the lid B The illustration shows the case where the product is divided into small portions via a cut line C made on the surface. FIG. 2 shows an example of the expanded shape of the rectangular container A, in which side plates 2, 2 are provided in series on the long side of the bottom plate 1, and end plates 3, 3 are extended on the other two sides. Furthermore, end flaps 4 are provided protruding from both end edges of the side plate 2, and inner flaps 5 are provided at the side edges. This product is assembled according to a conventional method as shown in Figure 4, and is assembled using any method such as pasting with adhesive or stitching to form a rectangular container A with an open top. do. That is, in assembling the container A having the above-described developed shape, first, the side plates 2 are made to stand up against the bottom plate 1, and then each end flap 4 is bent inward, and then the end plate 3 is attached thereon. to complete the box body. In addition, the inner flap 5
Fold it inward beforehand. An example in which three individual rectangular containers A constructed in this manner are arranged in series is shown in FIGS. 1 and 4.

Next, the lid B will be explained. As shown in FIG. 3, the lid body B consists of a lid plate 6 made of paperboard and a reinforcing cardboard sheet 7 that is integrally attached to the back side of the lid plate. The two are pasted together as described below, but first,
The developed shape is explained as follows. That is, as an example, a lid plate 6 of a size commensurate with the width of the entire opening surface when the three containers A are connected is prepared, and two opposing sides, which are the front and rear edges of the lid plate, are An adhesive flap 8 is attached. Although the auxiliary flap indicated by the reference numeral 9 does not necessarily have to be provided, it is preferable if it is provided, since the four sides of the lid plate can be attached to the container body A. Note that a corrugated cardboard sheet 7 having a size approximately equal to the size of the lid plate 6 is prepared separately from the lid plate, and is bonded to the back surface of the lid plate as described later.

It goes without saying that the size of the lid plate 6 and the corrugated cardboard sheet 7 to be attached to the back surface thereof should be commensurate with the width of the entire opening surface of the multiple containers A to which the lid plate is applied. For example, in Fig.
As shown by a or 7b, the dimensions may exceed the width of the opening surface. That is, in this case, the size of the corrugated cardboard sheet extends to the area of the adhesive flap 8 or the auxiliary flap 9 of the lid.

Next, the manner in which the cardboard sheet 7 is attached to the back surface of the lid plate 6 will be described. As an example, as shown in FIGS. 6a to 6c, on the overlapping surface when the lid plate and the corrugated sheet are attached, adhesive s is applied in a frame shape as shown by reference numeral 10 on the peripheral edge of the overlapping surface. The coating width l is 50 mm. In addition, as shown in FIGS. b to c, it may be formed into a spot shape (reference numeral 11) or a band shape (reference numeral 12), or it may be solidly painted.

Furthermore, in the present invention, a cut line C is formed on both the lid plate 6 and the reinforcing corrugated sheet 7 to facilitate opening.
As is clear from FIG. 1, in this case, the individual containers A are located in areas where they are adjacent to each other, or more precisely, between the individual containers A. Therefore, this cut line C allows the following configuration. That is, as shown in FIGS. 7a to 7e,
A cut line 20 is formed on the upper layer paperboard cover plate 6 constituting the cover body A, and a cut tape 21 is cut along the line C on the cardboard sheet 7 attached to the back side of the cover plate. Alternatively, as shown in FIG. 8, a liner cut formed by two parallel cutting lines 22, 22 may be provided only to the lower liner 7b of the corrugated board sheet 7. Also, as shown in Figure 9,
A single-sided corrugated cardboard sheet 7c can also be used as a material for reinforcing the paperboard cover plate, and in this case as well, cut lines are made in the same way as described above.

By the way, the code 24 in the figure is the cut tape 21.
Alternatively, it is a grip provided at the drawer end of the opening strip 23 formed by the two cutting lines 22. It is generally possible to provide this opening in the corrugated paperboard sheet in the lower layer of the lid, and in this case, a window 25 for exposing the opening is provided on the upper paperboard side. In addition, in the present invention, although it is necessary to provide the above-mentioned cut line C in the part of the lid 6 that constitutes the lid b, it is not necessary to provide the above-mentioned cut line C in the part of the adhesive flap 8 that is connected to the lid. 1 and 3 without the need to provide a cut line.
As shown in the figure, a mere perforation-like opening line may be provided.

By the way, in the present invention, the lid B having the cut line C as described above is placed over the rectangular container A after storing a predetermined product, and then the lid B is placed as shown in FIG. 1 or 4. , Cover the opening surface with the lid plate B having the adhesive flap 8 from above, bend the flaps 8, 8, and then paste this onto the exposed surface of the end flap 4 of the container A to a predetermined position. This completes the packaging. The state after packaging is completed is as shown in Fig. 1. To separate this product into individual subdivided containers, as shown in Fig. are separated from each other, thereby obtaining individual lidded containers A.

[Operations and Effects] Since the present invention has the above-described configuration, it exhibits the following functions and effects. In other words, since the lid B is composed of a paperboard lid plate and a reinforcing corrugated sheet that is integrally attached to the back side of the lid plate, the printability of the surface is superior to that of conventional exterior corrugated cardboard. It is so much better than this, and it is possible to print not only advertisements and advertisements for the stored products, but also product information such as postmarks. Further, an adhesive flap is connected to the end edge of the lid plate, and the paperboard is configured to cover not only the upper surface of the container but also the gable surface of the container through the adhesive flap. Therefore, most of the main exposed surface of the package is covered with paperboard, which has a high printing effect, and as a result, not only can a variety of information be displayed, but there are no restrictions on color printing. can fully demonstrate its functions.

In addition, a reinforcing cardboard sheet is integrally attached to the lid plate, and the body box, which constitutes the main body of the container, is entirely made of cardboard, so the product inside is highly protected. In particular, in the case of the present invention, the cardboard sheet 7 is integrally attached to the lid plate made of paperboard, so that this sheet is attached in a loose state (Figs. 11a to 11b).
(Reference), it has the following advantages: In other words, if the cardboard 31 is loose with respect to the outer box body 30 as shown in the figure, the cardboard will have little resistance to bending and twisting during handling, and will not be able to withstand impact. It only shows resistance. On the other hand, if the two are bonded together as in the present invention, the combined strength of the paperboard and corrugated board will be exhibited, and greater packaging strength will be obtained. Incidentally, the member indicated by the reference numeral 32 in FIG. 11 is a support body. Furthermore, as shown in Fig. 12, even if the box body 3
Even if the cardboard 31 is pasted to the top and bottom, if the body box A and the lid B are constructed separately from each other, the strength of the package as a whole will be weak, and the cardboard 31 will only have a cushioning effect in the top and bottom. It is nothing more than playing a song. On the other hand, as shown in FIG. 13, the cardboard sheet 7
If the adhesive flap 8 extended from the lid plate is attached to the container A, which is the body box, the strength of the package as a whole will be greatly increased, and it will not only have excellent cushioning properties. It also exhibits great resistance to bending and twisting during handling.

Next, the effect of providing a cut line as shown in FIG. 6 on the cover body B in this invention will be described.

In order to make opening easier, the opening part has traditionally been provided with perforated cut lines or the first
As shown in Figures 4 to 15, cutting tape 34 is pasted on the back side of the corrugated cardboard sheet 33, or two parallel cutting lines 35 are formed on the surface liner of the sheet 33 to facilitate the sheet separation. There are known examples of this. In cases where the cut line is simply a perforation or a cut tape 34 is simply pasted on as shown in Fig. 14, the cut end will stick out after cutting, and if the package is not completely peeled off at that point, it will remain as it is. There was a problem that made it impossible to display products. On the other hand, as shown in Fig. 15, two cutting lines 3
When 5 and 35 are provided, the separated portion can be kept relatively clean. However, even in this case, the surface liner of the corrugated cardboard sheet is often torn due to the tensile force applied by the inner cutting tape 34 when it is peeled off.
A clean cut along 5 cannot be obtained. On the contrary, according to the present invention, not only the lower corrugated sheet 7 and the upper cover plate 6 are separate from each other, but also the cutting line 20 formed on the cover plate is only one. Moreover, since the lid plates are kept in abutment with each other along the cutting line, even if the lower corrugated sheet 7 is torn off by the cut tape, the cut end will be the same as the sixth one. As clearly shown in Figures d or e, the cardboard sheet retains its beautiful state as if it were cut with a sharp knife, and the missing portion 36 of the cardboard sheet is completely covered and hidden by the upper layer of paperboard. Therefore, even after the package is divided into smaller pieces and opened, it exhibits a cosmetic effect that does not look like it has been broken and divided into smaller pieces. As a result, beautiful subdivided containers as shown in FIG. 10 can be obtained.

As detailed above, the container of the present invention has high handling strength during transportation, is not only resistant to bending and twisting, but also maintains packaging strength sufficient to withstand impact, and has good printability. In this way, various types of product information such as postmarks can be displayed without any restrictions in terms of color, which provides a novel characteristic as a cosmetic transport container.
