Description

  The present invention relates to a storage box for packing a plurality of individually packaged packages, for example, and particularly to a storage box in which a partition suitable for use in storing a blister pack in which a battery is packed is inserted.

  2. Description of the Related Art Conventionally, various packaging forms have been used when displaying batteries as products in stores. Among them, a transparent blister cover made of a resin material typified by polyethylene terephthalate (PET) or polystyrene (PS) is used. An individual package called a blister pack is widely used that contains a battery and is bonded and packaged with a mount made of paper or resin.

  In such blister pack collective packaging, a technique has been used in which as many blister packs as possible are accommodated in a storage box so as not to create a useless space in the storage box during transportation and storage. For example, when the blister pack is stored in the storage box as it is, there is no means for holding the blister pack, so it is clear that the blister pack will be damaged during transportation or dropping, and a partition made of cardboard or coated cardboard is used. Many methods are used to provide a space.

  For example, as shown in FIGS. 1A to 1C, each of the blister packs 1 in which the battery 2 is accommodated in the blister cover 1b and bonded to the mount 1a is die-cut from cardboard paperboard or the like to a predetermined size and assembled into a predetermined box shape. In the storage box 4, the storage box 4 was stored and transported and stored in a space partitioned by a grid-like partition indicated by reference numeral 3.

  However, when such a partition 3 is used, the blister cover 1b surface of the blister pack 1 is damaged due to vibration during transportation, resulting in a problem that merchantability is impaired. This is because, as shown in FIGS. 2A and 2B, when the lattice-like partition 3 is used, the blister pack 1 is not fixed because each blister pack 1 is accommodated as it is in each space provided by the partition 3. This is because friction occurs between the blister pack 1 and the partition 3 due to vibration during transportation. Further, since the mount 1a is in contact with the bottom surface of the storage box 4, the lower end of the mount 1a is likely to be bent or bent. 2A is a top view showing a state of accommodation, and FIG. 2B is a cross-sectional view of a portion indicated by aa ′ in FIG. 2A.

  Also, as shown in FIG. 3, the grid-like partition 3 has a large number of parts and requires manual assembly, which is expensive and requires complicated steps. Moreover, since it is a structure which supports the mass of the blister pack 1 only with a base_sheet | mounting_paper, when the impact is added, the base_sheet | mounting_paper 1a becomes easy to generate | occur | produce further, and also has the fault that merchantability is impaired remarkably.

  Furthermore, in a storage battery such as a nickel metal hydride battery, problems such as heat storage due to self-discharge during transportation and storage may occur depending on the amount of charge. Therefore, when the blister pack 1 is stored in the storage box 4, it is constant between the blister packs. It is known that it is necessary to provide a space. However, since the blister packs 1 are not fixed when the grid-like partitions 3 are used, the blister packs 1 may be close to each other via the partitions 3.

  Therefore, it has been proposed to use partitions as shown in Patent Documents 1 to 3 below.

Japanese Utility Model Publication No. 4-19412 Japanese Patent Publication No. 7-10694 JP 2002-326623 A

  In the above-mentioned Patent Documents 1 to 3, a slit is provided in the partition, and the lower end or upper end of the mount of the blister pack is inserted into the slit. In such a partition, by providing slits so as to have an interval larger than the thickness of the blister pack, it is possible to suppress the blister pack from moving in the blister pack alignment direction in the storage box, and to rub the blister pack and the partition. Can be prevented.

  However, in each of Patent Documents 1 to 3, since the blister pack is fixed by inserting the lower end or the upper end of the mount into the slit, the unfixed end is easy to move in the blister pack alignment direction. For this reason, the blister packs come into direct contact with each other, and the blister cover is rubbed, the mount is bent, and the bend occurs. Further, since the battery housing portions are likely to be close to each other, there is a possibility that sufficient safety during battery heat storage cannot be ensured.

  In addition, since the lower end of the mount comes into contact with the partition case or the storage box, the lower end of the mount is particularly likely to be bent or bent.

  Accordingly, an object of the present invention is to provide a storage box that solves the above-described problems and can sufficiently ensure the merchantability of blister packs and the safety during transportation and storage.

  In order to solve the above-described problems, the present invention provides a storage box in which a partition for storing a blister pack including a mount and a blister cover serving as a storage section for an article is stored in the storage box in an aligned state. The partition is formed continuously from the first protrusion to the second protrusion, the recess having the first protrusion and the second protrusion at both ends, and larger than the thickness of the blister pack. And a plurality of slits provided in parallel, and when the partition is inserted into the storage box, a space is provided between the bottom surface of the recess and the bottom surface of the storage box. is there.

  In this invention, when the partition is inserted into the storage box, a space is formed between the bottom surface of the recess of the partition and the bottom surface of the storage box. When the blister pack is stored in the storage box provided with such a partition, the three sides of the blister pack, the lower end, the right side, and the left side, are inserted into the slit. The blister pack is self-supported by being held from below by the bottom surface. At this time, by adjusting the space between the bottom surface of the recess and the bottom surface of the storage box, the lower end portion of the blister pack protruding below the bottom surface of the recess can be prevented from contacting the bottom surface of the storage box.

  Moreover, since the space | interval of slits is made larger than the thickness of a blister pack, while preventing the contact between blister packs, space can be maintained between blister packs.

  According to the present invention, it is possible to prevent folding or bending of the mount of the blister pack and rubbing of the front portion of the blister cover. Moreover, even if it is a case where the blister pack for storage batteries is accommodated, since a storage battery does not adjoin, safety can be maintained.

  An embodiment of the present invention will be described below with reference to the drawings.

  FIG. 4 is a perspective view showing a configuration example of the storage box 15 to which the present invention is applied. A partition 13 for inserting the blister pack 11 into the storage box in an aligned state is inserted into the storage box 15. For example, the blister pack 11 and the partition 13 can be taken in and out from the upper surface of the storage box 15. The blister packs 11 are inserted and held in the plurality of slits 14 provided in the partition 13.

  For example, as shown in the perspective view of FIG. 5A and the front view of FIG. 5B, the blister pack 11 held by the partition 13 is formed on a transparent blister cover 11b made of a resin material such as polyethylene terephthalate (PET) or polystyrene (PS). It is obtained by forming a battery housing portion 11c capable of housing the battery 12, and housing one or a plurality of batteries in the battery housing portion 11c, and then adhering to a mount made of paper or resin.

  FIG. 6 is a perspective view showing an example of the structure of the partition 13. FIG. 7 is a developed view of the partition 13 shown in FIG. The partition 13 holds a side surface portion 13 a that rises along the side wall of the storage box 15, a partition upper surface 13 b provided so as to be substantially parallel to the upper surface of the storage box, and the blister pack 11, and the blister cover of the blister pack 11 A holding portion side wall 13c provided along the side surface of 11b and a holding portion bottom surface 13d for holding the lower portion of the blister cover 11b from below include a side surface portion 13a, a partition upper surface 13b, a holding portion side wall 13c, and a holding portion bottom surface 13d. The holding portion side wall 13c, the partition upper surface 13b, and the side surface portion 13a are sequentially bent and provided so that a recess for holding the blister pack 11 is provided between the two protruding portions. Yes. In addition, a desired number of continuous slits 14 for inserting the blister packs 11 after assembling the partition 13 are mutually connected to the recesses that extend from the one partition top surface 13b to the other partition top surface 13b via the holding unit bottom surface 13d. It is provided in parallel.

  As shown in FIGS. 8A to 8C and FIGS. 9A to 9C, three sides other than the upper part of the blister pack 11 are inserted into the slits 14 of the partition 13 having such a configuration, and further stored in the storage box 15. Transported and stored.

In the developed view of FIG. 7, such a partition 13 has a solid line m of the rectangular base material 13 ′ as a mountain fold, a chain line v as a valley fold, and a mountain fold part and a valley fold part as substantially right angles. Is obtained. Note that the partition 13 is configured such that the height h ₁ of the side surface portion 13a is higher than the height h ₂ of the holding portion side wall 13c. This is because when the blister pack 11 is inserted into the slit 14, the lower portion of the mount 11a penetrates the holding portion bottom surface 13d, and the mount 11a is configured to have a difference that is greater than the length protruding below the holding portion bottom surface 13d. Thereby, the mount 11a does not come into contact with the bottom surface of the storage box, and the mount 11a can be prevented from being bent or bent.

The height h ₂ of the holding portion side wall 13c is not particularly limited as long as the blister pack 11 can be stably accommodated and the height h ₂ can prevent contact between the blister packs 11, but the height of the battery accommodating portion 11c of the blister pack 11 is not limited. It is preferable to make it smaller than the height. This is because waste of the material used for the partition 13 can be eliminated.

The width w ₁ of the holding portion bottom surface 13d is configured to be larger than the width w ₂ of the battery accommodating portion 11c of the blister pack 11 and smaller than the width w _{3 of the} mount 11a. In particular, it is preferable to make the difference between the width w ₁ of the holding portion bottom surface 13d and the battery accommodating portion 11cw ₂ of the blister pack 11 as small as possible. This is because the stability of the blister pack 11 is increased.

  The slits 14 are configured such that the interval L between the slits 14 is larger than the thickness t of the blister packs 11 in order to prevent contact between the blister packs 11. The width of the slit 14 is preferably configured to have a clearance of about 1 mm to 3 mm with respect to the thickness of the mount. If the difference between the width of the slit 14 and the thickness of the mount 11a is too small, it will be difficult to insert the blister pack 11 when the blister pack 11 is accommodated, and the mount 11a may be rubbed. It becomes easy to move. In addition, when the mount 11a and a part of the blister cover 11b bonded to the mount 11a are inserted into the slit 14, the above-described clearance is provided for the total thickness of the mount 11a and the blister cover 11b. Is preferred.

Further, the slit 14 is configured such that, after the partition 13 is assembled, the linear distance d _{1 at} both ends of the slit 14 is larger than the width w _{3 of the} mount 11a. The difference between the linear distance d _{1 at} both ends of the slit 14 and the width w _{3 of the} mount 11a is preferably as small as possible. This is because the stability of the blister pack 11 is increased. Further, the linear distance d ₂ from one end of the slit 14 provided on one partition upper surface 13b to the boundary portion between the other partition upper surface 13b and the holding portion side wall 13c is made smaller than the width w _{3 of the} mount 11a. It is preferable to make it. The width of the holding portion bottom 13d is a smaller than the width w ₃ of the mount 11a, the boundary from one end of the slit 14 provided on one of the partition top 13b, and the other partition top 13b and the holding side walls 13c When the linear distance d ₂ to the portion is larger than the width w ₃ of the mount 11a, depending on the configuration of the blister pack 11, one side of the mount 11a is detached from the slit 14 and the stability of the blister pack 11 is impaired. This is because there is a risk of losing.

  In addition, although it is also possible for the slit 14 to wrap around from the partition upper surface 13b and to provide a slit end portion on the side surface portion 13a, it is not preferable because it may cause a decrease in strength of the partition 13.

  As the material of the partition 13, cardboard such as A flute, B flute, E flute, and G flute and paperboard such as a coat ball or a manila ball can be used. These materials may be selected depending on the weight of the blister pack 11 to be packed, the number of packings per storage box, and the like. As a partition for the blister pack that houses the battery, for example, E flute cardboard is preferably used from the viewpoint of strength and thickness.

  Further, as the material of the storage box 15, cardboard such as A flute and B flute may be used depending on the weight of the blister pack 11 to be packed and the number of packings per storage box.

  In the partition 13 having such a configuration, the blister pack 11 is fixed as shown in FIG. 9B which is a top view of FIG. 8B shown in FIG. 9A and a cross-sectional view shown by bb ′ of FIG. 9A. The packs 1 and the blister pack 1 and the storage box 15 and the partition 13 do not come into contact with each other, and the front part of the blister cover 11b where the battery 12 which is a product can be confirmed is rubbed and the merchantability is not impaired.

  Also, as shown in FIG. 9B and FIG. 9C, which is a front view indicated by cc ′ in FIG. 9A, the holding portion bottom surface 13d of the partition 13 and the bottom surface of the battery accommodating portion 11c of the blister cover 11b come into contact with each other. Although 11 is held, there is a possibility that some rubbing may occur at this contact portion, but it is difficult for consumers to see when the product is displayed at the store, and the merchantability is not impaired.

  In addition, since the partition 13 is configured such that the lower end of the mount 11a that is inserted into the slit 14 and protrudes under the holding portion bottom surface 13d is higher than the lower end of the side surface portion 13a of the partition 13, the blister pack 11 The lower part does not contact the bottom surface of the storage box 15. For this reason, the impact at the time of transporting or dropping of the storage box 15 is not transmitted only to the mount 11a, and the partition 13 absorbs the impact and prevents the mount 11b from being bent or bent. 9C indicates a space that is surrounded by the partition 13 and is not exposed to the outside.

  Furthermore, since the blister packs 1 can maintain an appropriate distance, the battery 12 does not approach. For this reason, even if it is a case where the blister pack which accommodated the storage battery is accommodated, it has high safety.

  In addition, the partition 13 is not restricted to the above structure, For example, it is good also as the partition 23 of a structure as shown to FIG. 10A thru | or FIG. 12C. 10A and 10B show a state in which the blister pack 11 is accommodated in the partition 23, FIG. 11 is a developed view of the partition 23, FIG. 12A is a top view of FIG. 10B, and FIG. 12B is a dd of FIG. FIG. 12C is a front view indicated by ee ′ in FIG. 12A. Also, the same reference numerals are assigned to the same or corresponding parts as those in the configuration of FIGS.

  In such a partition 23, in order to further secure the space in the storage box 15, the raised portion is formed by providing a fold at the bottom of the partition 23. As shown in FIG. 11, the partition 23 and the raised portion are continuously formed by folding the solid line portion of the base material 23 ′ into a mountain fold and the chain line portion into a valley fold. Note that this space can be freely set by adjusting the width of the folded portion 23a. For example, the stability of the partition 23 can be improved by providing the tab 23a and the insertion port 23b, and inserting and fixing the tab 23a in the insertion port 23b.

  Further, as shown in FIGS. 13A to 13B, the raised portion may be a separate part from the partition 23. In this case, in FIG. 13A to FIG. 13B, the folded portion is formed so as to have a square cross section, but if there is no problem in strength or the like, either the bottom surface or the top surface may be omitted.

  EXAMPLES Hereinafter, the present invention will be specifically described with reference to examples. However, the present invention is not limited to these examples. In the following examples, the shape of the partition was changed to accommodate the blister pack, and the folding of the mount and the blister cover were confirmed.

<Example 1>
[Production of blister pack and storage box]
Using a transparent A-PET with a thickness of 0.3 mm as the blister cover material and a coated ball with a weight of 450 g / m ² as the mount material, 4 AA nickel metal hydride storage batteries with a mass of about 30 g are accommodated in the blister cover. After that, they were bonded together to form a blister pack. Further, A flute corrugated cardboard (thickness: about 5.0 mm) was used as the material of the storage box, and after die cutting and assembly, the bottom surface portion was fixed to prepare an A-type storage box.

[Production of partitions]
E flute corrugated cardboard (thickness: about 1.5 mm) was used as the partition material, and the die was cut as shown in FIG. 7, and 10 slits were cut in parallel, and then assembled into the configuration shown in FIG. The vertical and horizontal dimensions after assembling the partitions were just large enough to be stored in the storage box.

[Blister pack accommodation]
The partition was accommodated in the storage box produced as described above, each of the 10 blister packs was stored in the slit of the partition, and the upper lid of the storage box was fixed.

<Example 2>
As a partition, 10 blister packs were accommodated in the same manner as in Example 1 except that the die was cut as shown in FIG. 11, 10 slits were cut in parallel, and the assembly was assembled as shown in FIG. A storage box was prepared.

<Comparative Example 1>
As a partition, a container box containing 10 packs of blister packs was produced in the same manner as in Example 1 except that the parts shown in FIG. 3 were cut out and assembled into the structure shown in FIG.

  These storage boxes were subjected to (a) drop test and (b) sin wave vibration test as follows. The test was conducted with a sample number of 10 packs each.

(A) Drop test The storage boxes of the examples and comparative examples were dropped from a height of 75 cm with the bottom surface of the storage box being horizontal, and the number of blister packs in which the mount was broken after dropping was confirmed.

(B) sin wave vibration test The container of each example and comparative example was placed under conditions of a frequency of 5 to 50 Hz, an acceleration of 0.76 G, and a sweep speed of 9 Hz / min, and a 20 minute sine wave vibration test was performed. The number of blister packs that rubbed on the front surface of the blister cover was confirmed.

Table 1 below shows the test results.

  As can be seen from Table 1, in Example 1 and Example 2 using the partition using the configuration of the present application, folding of the mount and rubbing of the front portion of the blister cover can be prevented.

  On the other hand, in Comparative Example 1 using a conventional grid-like partition, the folding of the mount and the rubbing of the blister cover frequently occurred. This is because the blister pack of Comparative Example 1 is configured to be self-supporting in the storage box, so that the impact of the test is concentrated on the lower end of the mount, and the lower end of the mount is broken. Further, since the blister pack was accommodated in the space just divided by the grid-like partition without being fixed, the partition and the blister cover were in contact with each other, and rubbing occurred.

  From the above results, when the partition having the configuration of the present application is used, it is possible to prevent the blister pack from being damaged as compared with the conventional partition.

  As mentioned above, although embodiment of this invention was described concretely, this invention is not limited to the above-mentioned embodiment, The various deformation | transformation based on the technical idea of this invention is possible.

  For example, the blister pack used in the above-described embodiment may accommodate a primary battery, a battery having a shape other than a cylindrical shape, or a container other than the battery.
