JPH09240738A - Shock absorber for can, bottle, etc - Google Patents

Abstract

PROBLEM TO BE SOLVED: To prevent a can from being dented and a bottle from breaking by forming on each side of a rectangular cardboard a ridge in the shape of an inverted V formed of the cardboard bent upward and tuned down halfway and by forming notches at prescribed intervals therein on which for cans, bottles or the like to rest. SOLUTION: Each of flap parts 2 on two sides of a rectangular cardboard 1 is formed into a ridge 5 in the shape of an inverted V by being bent upward from a discontinuous line of incisions 3 and tuned down from the median line 4 of the bent part as the apex. In these ridges 5 notches 6 are provided at prescribed intervals so that beverage cans can be held with their respective upper parts and bottom parts in the notches. Each of the beverage cans is supported on upper part-holding arc-shaped parts 7, 8 and on bottom part-holding arc-shaped parts 9, 10 and leaves a space under the drum part. Even if the package collapses during distribution and the can is displaced somewhat, the two ends of the can are fixed by partition boards. The shock absorber obtainable according to this constitution is simple in structure, effective on a beverage can, bottle, etc., and its disposal as waste involves no problems relating to environmental hazards.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cushioning material effective for cans, bottles, etc. laid in a packaging box such as a cardboard box.

[0002]

2. Description of the Related Art Beverage cans such as juice cans and coffee cans are generally packed flat in a packaging box such as a cardboard box and placed in the distribution process. Beverage cans contained therein may be dented due to buffering or the like.

Further, in bottle products such as beverage bottles, a fitting recess cushioning material made of a plastic foam material conforming to the shape thereof, an aerated plastic sheet or the like is used to prevent breakage. As described above, the plastic molded product has a problem of environmental pollution when it is disposed of after use, and a solution for it has been demanded.

[0004]

In view of the above points, the present invention is effective not only for preventing the occurrence of dents in can products such as beverage cans but also for preventing damage to bottle products such as beverage bottles. The purpose is to provide a cushioning material.

[0005]

Means for Achieving the Object To achieve the above object, the present inventor has conducted extensive studies and as a result, a dent at the time of dropping often occurs near the center body of a beverage can. Since the compressive strength is high near the part, dents are unlikely to occur, and if there is no space between the center body of the beverage can and the bottom of the box, it will cause dents, for example of aerated plastic sheet (air cap) Paying attention to the fact that even soft cushioning material such as this will cause dents when present in this space, the dents can be formed by supporting both ends of the beverage can so that the vicinity of the center body of the beverage can forms a space. Therefore, they have found that the cushioning material constructed in such a erected shape is also effective for preventing breakage of the beverage bottle, and completed the present invention.

That is, the cushioning material for cans, bottles, etc. of the present invention is
Both side flaps of the rectangular paper board are both bent upward and folded back from the middle of the bent part to form a mountain-shaped protrusion on both sides, and the mountain-shaped protrusion has a can,
It is characterized in that notches for mounting and holding bottles and the like are formed at predetermined intervals.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in detail with reference to the drawings for better understanding.

First, in FIG. 1, both side flaps 2, 2 of a rectangular paper board 1 are bent upward through cuts provided discontinuously at the positions 3, 3, and the folded parts Inverted V-shaped protrusions 5 and 5 formed by folding back downward with the central portions 4 and 4 as apexes, the cutout portions 6 and 6 (so that the upper and bottom portions of the beverage can are placed and held respectively. As an example, there is shown a perspective view of an embodiment in which the notches shown are symmetrical arcuate curved surfaces) provided at predetermined intervals, that is, so that the beverage cans to be placed are connected to each other. The both side flap portions 2 and 2 are shaped to be easily bent at the central portions 4 and 4, but may be bent at the central portions if necessary. FIG. 2 is a development view of the cushioning material shown in FIG. The beverage can, as shown in FIG.
The lower side of the can body portion is supported by 8 and the bottom installation arcuate portions 9 and 10 to form a space. Therefore, immediately after the beverage can is installed in the cutout portion, it is supported at four points 7, 8, 9, and 10. Even if this state collapses and moves during distribution, since both ends of the beverage can are fixed by the partition plates, they are supported at at least three points and are not removed from the notches. Further, when the movement of the beverage can toward both ends is severe, both side flap portions 2 and 2 of this cushioning material are bent into mountain folds at the central portions 4 and 4 to form an inverted V shape. Since the elastic action that tends to become flat acts, when the product is installed in the packaging box, the folded back end of the flap portion is brought into close contact with the inner surface of the packaging box.

In order to hold the beverage bottle in the structure shown in FIG. 1, FIG. 3 has an inverted V-shaped protrusion with an arcuate curved notch corresponding to the upper portion of the small diameter of the beverage bottle. Shows another embodiment in the case of providing notches having an arcuate curved surface corresponding to the large-diameter bottom of a beverage bottle, respectively.

FIG. 4 shows another embodiment in which trapezoidal projections 11 and 11 are formed instead of the inverted V-shaped projections shown in FIG. 1, and FIG. 5 is a development view thereof. . In this configuration, two fold lines 12 and 13 are provided on both side flap portions, respectively, so that the space between the top placing arcuate portions 7 and 8 of the beverage can and the space between the bottom placing arcuate portions 9 and 10 of the beverage can are formed. Since it is expanded, large-sized beverage cans, bottles, etc. can be stably placed.

Next, in order to clarify the effect of the cushioning material of the present invention for preventing the depression of the beverage can and the effect of preventing the beverage bottle from being broken, the results of a drop test under the following conditions are shown.

[Beverage can dent prevention effect] 1. Samples to be tested: (1) Beverage can; 195 ml juice inlet diameter 5.3 cm

2. Method: A drop test was carried out as follows.・ Pretreatment; 20 ℃ -60% RH / 24 hours ・ Height 0.8, 1.2m 2 times, bottom drop ・ n = 2 (sample number = 2 boxes)

3. The results are collectively shown in Table 2.

[0019]

[Table 2]

4. Consideration: From the results shown in Table 2, the drop strength of the cardboard bottom pad is 0.8 m or less for both A / F and B / F, whereas the drop strength of the cushioning material of the present invention is 1.2 m or more. Therefore, the cushioning material of the present invention is judged to be effective for bottles.

The material of the beverage can which is the object of the cushioning material of the present invention may be aluminum, steel or the like which is generally used. The bottle container is not limited to the bottle, and may be made of synthetic resin such as PET bottle.

[0022]

As described above, since the cushioning material of the present invention is made of paper board, unlike the cushioning material made of plastic, there is no problem of pollution due to disposal, and the structure is simple and the beverage is It is possible to provide an effective cushioning material for cans, bottles and the like. Further, since the cushioning material of the present invention has a shape that stably supports both ends of beverage cans, bottles, etc., it is possible to determine the position of the beverage cans, etc., and perform positioning when packaging many types of beverage cans, etc. Since it is easy, there is an advantage that the packaging efficiency can be improved.
