[Action]

 The shock-absorbing inner frame of the present invention is used by inserting it into the box so that the lower end surface abuts the inner bottom surface of the box. Then, the contained products such as bottled products, canned products, electric appliances, etc. are housed in the box so as to be supported by the plurality of projecting portions forming the buffer inner frame. The shock-absorbing inner frame of the present invention supports the contents from below with a plurality of overhanging portions and absorbs the impact from below, and the side walls other than the overhanging portions support the contents from the side and the impact from the side. Alleviate. That is, the cushioning inner frame of the present invention is a single member, and has the functions of two members, that is, the cushioning member support member 21 and the side wall member 22 shown in FIG. Therefore, the workability of the insertion work when using the cushioning inner frame of the present invention is higher than the workability when using the cushioning member shown in FIG.

The buffer inner frame of the present invention may or may not have a shield-shaped sleeve portion extending in the vertical direction on the base side of the overhang portion. In the case of having a shield-shaped sleeve, the presence of this sleeve improves the cushioning performance against side impacts. Also, by forming the sleeve so that the inner end of the sleeve contacts the side wall of the container, the container can directly support the container from the side. The shield-shaped sleeve portion can be formed, for example, by notching the tip-side upper portion of the overhang portion. Further, in the shock-absorbing inner frame of the present invention, there may be a case where the upper side of the tubular body has a lid portion continuing from the side wall of the tubular body, and a case where the lid portion is not provided at all. When the cover has a lid, the vertical support performance and the cushioning performance are improved without lowering the workability of the insertion work during use.

 An embodiment of the buffer inner frame of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a buffer inner frame of the embodiment, and FIG. 2 is a sectional view taken along the line AA shown in FIG. Further, FIG. 3 is a vertical cross-sectional view of the central portion when the buffer inner frame of the embodiment is used. 4 is a developed view of the cushioning inner frame of the embodiment, FIG. 5 is a perspective view showing a state during assembly, and FIG. 6 is a plan view showing an example of a shape when unused or stored.

The buffer inner frame 1 shown in FIGS. 1 and 2 is made up of a single cardboard-made tubular body 2, and the tubular body 2 has a rectangular cross-section. A part of the lower side wall of the tubular body 2 is recessed into the internal space of the tubular body 2 to form four projecting portions 3. The upper portions on the tip end side of these overhanging portions 3 are largely cut out, and as a result of this notch, a shield-like sleeve portion 4 extending in the vertical direction is formed on the base side of each overhanging portion 3. Further, the corner portion 5 of the side wall located immediately above the overhanging portion 3 is arcuately or obliquely cut out, and this cutout reduces the portion that becomes a catch when the buffer inner frame 1 is inserted into the box, Easy to insert. As a result of the notch on the upper end side of the overhanging part 3 and the notch at the corner of the side wall located immediately above the overhanging part 3, a window 6 is formed near the center of each overhanging part 3 and above it. . Further, an inner lid portion 7a and an outer lid portion 7b continuing from the side wall are provided on the upper side of the tubular body 2. Further, the inner lid portion 7a is provided with an opening 8 for holding the upper portion of the contained article by projecting the upper portion of the contained article from the inner lid portion 7a. The corner 9 on the tip side of the inner lid portion 7a is cut out in an arc shape in order to facilitate the opening of the inner lid portion 7a.

As shown in, for example, FIG. 3, the buffer inner frame 1 has a lower end face abutting an inner bottom face of the box 10 inside a box 10 of an inner size in which the side surface of the tubular body 2 can be inscribed. It is used by inserting into. At this time, each overhanging portion 3 supports the contained object 11 from below, and also functions as a cushioning member against an impact from below. Further, the inner end surface of each sleeve portion 4 abuts on the outer side surface of the container 11, supports and restrains the container 11 from the side surface, and functions as a buffer member against a side impact. The inner lid portion 7a supports and restrains the upper portion of the stored article 11 by projecting the upper portion of the stored article 11 from the opening 8. Then, the outer lid portion 7b is tilted in the direction of the arrow a shown in FIG. 1 to cover the inner lid portion 7a, thereby further improving the support performance and the cushioning performance in the up and down directions.
