Abstract

PURPOSE:To provide a packaging cushioning material which prevents dust entry and eliminates the need for a bag intended therefor by engaging a lower cushioning material and upper cushioning material to enclose articles to be packaged. CONSTITUTION:Corrugated fiberboard cases 4 containing articles 1, a lower cushioning material 2 and an upper cushioning material 3 with a lid 5 covered thereon are transported on an individual basis or in a stacked form in a few tiers. When the corrugated fiberboard case 4 is subjected to shocks or vibrations in transit, the lower cushioning material 2 and the upper cushioning material 3 therein absorb such shocks or vibrations to prevent the articles 1 against breakage. In the case of dusts entering through a gap between the corrugated fiberboard case 4 and the lid 5 and the seams of the corrugated fiberboard case 4 in storage or transit, the engagement of these two cushioning materials encloses the articles 1 to prevent the contamination thereof with the dusts.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to a cushioning material for packaging precision instruments.

[Conventional technology]

Fig. 3 is an exploded perspective view showing a conventional packaging material, and Fig. 4 is a cross-sectional view.
) is a bag for packaging the packaged item (1), (7) is an adhesive tape that closes the opening of the bag, and (8) is for protecting the underside of the packaged item (1) packaged in the bag (6). The lower cushioning material (9) is the upper cushioning material that protects the upper side of the packaged object (1) packaged in the bag (6), and (4) is the lower cushioning material ((4) that holds the packaged object (11) in between. 8) and a cardboard box for storing the upper cushioning material (9), (5)
) is the lid of the cardboard box (4).

Next, the effect will be explained. The cardboard box (4) packed in the bag (6) and containing the next packaged item (1), the lower cushioning material (8), and the upper cushioning material (9) and the lid (5) can be used alone or in several stacks. Transported and transported. If shock or vibration is applied to the cardboard box (4) during transportation, the lower cushioning material (8) and upper cushioning material (9) inside the two cardboard boxes (4) will absorb the shock and vibration, The package (1) is protected from being destroyed. Also, if dust enters through the gap between the cardboard box (4) and the lid (5), or the seam of the cardboard box (4), etc. during warehouse storage, transportation, etc.

Place the bag (6) to prevent the packaged item (1) from getting dirty with dust.
) is packaged by

[Problem to be solved by the invention]

Since the conventional packaging cushioning material is constructed as described above, two bags (
6) to wrap the item to be packaged (1), and then wrap it with adhesive tape (
7) The opening of the bag (6) had to be stopped, making the packaging work difficult and the packaging material expensive.

This invention was made to solve the above-mentioned problems, and aims to provide a cushioning material for packaging that prevents dust from entering and does not require two bags.

[Next Means for Solving the Problems] The packaging cushioning material according to the present invention is obtained by fitting outer frames of an upper cushioning material and a lower cushioning material.

[Effect]

The packaging cushioning material according to the present invention fits into the outer frames of the upper cushioning material and the lower cushioning material.

Since the object to be packaged is completely surrounded, the intrusion of dust can be prevented, and there is no need to wrap the object in a bag.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings. 1st
In the figure and FIG. 2, (1) is the item to be packaged.

(2) is a lower cushioning material that protects the lower side of the packaged item (1);
(3) is an upper cushioning material that protects the upper side of the packaged item (1);
(2a) and (3a) are the joint part of the lower cushioning material and the joining part of the upper cushioning material, respectively, and the cushioning materials (21, (3)
The frame (4 sides) has a shape as shown in Figure 2. (4
) is a cardboard box that stores the lower cushioning material and the upper cushioning material sandwiching the packaged item (1), and (5) is the lid of the cardboard box (4).

Next, the effect will be explained. A cardboard box (4) containing the item to be packaged (11), a lower cushioning material (2), and an upper cushioning material (3).
) and the lid (5) are transported singly or stacked in several tiers. If impact vibration is applied to the cardboard box (4) during transportation/transportation, the lower cushioning material (2) and upper cushioning material (3) inside the two cardboard boxes (4) will absorb the impact and vibrations and prevent the packaging from occurring. Protects object (1) from being destroyed. or.

Cardboard boxes (4) and lids (
If dust enters through the gap in 5) or the joint of the corrugated pole box (4), use the lower cushioning material (2) and the upper cushioning material (3) to prevent the packaged item from getting dirty with dust.
are fitted together to surround the packaged object (1).

〔Effect of the invention〕

As described above, according to the present invention, the lower cushioning material and the upper cushioning material are fitted together to surround the packaged item and prevent dust without using a single bag, so the packaging material can be made inexpensive.
This has the effect of making packaging work easier.
