Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an improvement of a packaging container used for packaging a required number of button type batteries in line.

[Conventional technology]

As this type of packaging container, for example, as shown in FIG. 6, a plastic sheet of styrene resin or the like is vacuum-molded to form battery housing recesses 2 corresponding to the shape of the battery B vertically and horizontally at a predetermined number and at a predetermined pitch. It will be recessed. In order to make it easy to take out the container P, which is a molded product, from the mold, all the battery accommodating recesses 2 are formed in a tapered shape with a draft. When the empty packaging container P is stored in a warehouse or when the batteries B are housed in a box and packed, the many packaging containers P are stacked in a vertical multi-stage. At this time, the packaging container P on the upper stage side is stacked. The outer tapered surface of the bottom portion of the battery accommodating concave portion 2 in is fitted into the taper inner surface of the opening portion of the battery accommodating concave portion 2 of the lower-side packaging container P, so that It prevents the slipping out and regulates the lateral displacement between the upper and lower packaging containers P to maintain the stacked state.

[Problems to be solved by the device]

However, in the packaging container formed as described above, when a large number of packaging containers P are stacked, the upper and lower battery housing recesses 2
Since the fitting depth between the two is likely to vary and the stacking height is not constant, there have been problems such as difficulty in standardizing the packing form especially when performing automatic box packing. Especially, the problem is that if the tapered surfaces of the upper and lower battery accommodating recesses 2 become tightly fitted to each other, it becomes difficult for the packaging containers P to be separated from each other while being overlapped with each other, which hinders the battery packaging work and the empty packaging container work. The point is to come. In this regard, it has been proposed to apply a release agent to the packaging container P so that the packaging containers P are easily separated from each other.
This is not a preferable measure, because the surface of is soiled with oil.

The present invention has been made to solve these problems, and the stacking height of packaging containers can be made constant,
Another object of the present invention is to prevent the stacked packaging containers from coming off easily afterwards and to improve the handleability.

[Means for Solving the Problems]

In the present invention, for example, as shown in FIG. 1, a group of recessed battery housing recesses 2 is formed in an upper plate 3 made of a plastic sheet, and a peripheral side wall 5 is expanded downward from the periphery of the upper plate 3. On the premise of a battery packaging container that is connected to the upper plate 3, a ridge 4 is provided at the intersection of the upper plate 3 and the peripheral side wall 5.
It is provided so as to rise higher than the upper plate 3 along the periphery thereof, and concave portions 7 are formed at several points of the convex stripes 4. When the packaging containers P are stacked vertically, the recess 7 of the upper and lower packaging containers P is placed so that the bottom surface 7a side of the recess 7 of the upper packaging container rests on the ridge 4 of the lower packaging container P. The position is shifted.

[Action]

When the same packaging containers P are stacked on top of each other,
The recess 7 of the ridge 4 functions to regulate the depth of fitting between the upper and lower battery housing recesses 2. That is, the packaging container P
In the stacked state, the bottom 7a side of the recess 7 of the upper packaging container P is placed on a portion other than the recess 7 of the convex strip 4 facing the lower packaging container P, and the upper and lower battery accommodating recesses 2.2 The overlapping dimensions are regulated so that they do not fit deeply together.

Further, since the recess 7 is formed to be shallower than the height of the peripheral side wall 5, when the packaging containers P are stacked, the inner surface of the peripheral side wall 5 of the upper side packaging container P below the recess 7 is the lower side packaging. By abuttingly fitting the upper outer surface of the peripheral side wall 5 of the container P, the lateral displacement between the packaging containers P is regulated.

[Effect of device]

According to the packaging container of the present invention configured as described above, among the packaging containers P stacked in the upper and lower stages, the ridges 4 of the upper packaging container P are placed on the ridges 4 of the lower packaging container P. The bottom surface 7a side of the concave portion 7 provided at a predetermined position is placed.
Therefore, it is possible to regulate the deep fitting between the battery housing recesses 2, 2 and to easily separate the stacked packaging containers P from each other without using a release agent or the like. There is no variation in stacking height, which is advantageous for standardization of automatic box packaging. In addition, the lateral displacement of the packaging containers P can be regulated by partially fitting the upper and lower peripheral side walls 5, and the stacked state can be stably maintained. Therefore, battery packing work and empty packing container rearrangement work can be performed efficiently.

〔Example〕

An embodiment of a battery packaging container according to the present invention will be described with reference to FIGS. 1 to 5.

1 and 4, the container body 1 is a rectangular upper plate 3 having a battery accommodating recess 2 corresponding to the shape of a button-shaped battery B by vacuum forming a plastic sheet of styrene resin, expanded polystyrene resin, or the like. A peripheral side wall 5 is formed continuously from the front, rear, left and right ends of the upper plate 3 downwardly through a ridge 4 having a groove-shaped cross section so as to extend outward.

The upper plate 3 is formed with a plurality of recessed grooves 6 whose upper surface is open in parallel, and each recessed groove 6 has a width smaller than the outer diameter of the battery B and a depth substantially equal to the height of the peripheral side wall 5. Is set to.

At the upper part of the opening in each groove 6, the battery accommodating recesses 2 for accommodating the battery B straddling the groove 6 are formed at a predetermined pitch in the longitudinal direction of the groove 6. The battery housing recess 2 has a tapered shape with a draft and is set to be shallower than the depth of the recess groove 6.

The ridges 4 are formed in a groove shape in cross section so as to rise higher than the upper plate 3, and even when the entire container body 1 is made of a plastic sheet, it exerts a shape-retaining function of preventing its shape collapse. Two concave portions 7 each having a depth shallower than the height of the peripheral side wall 5 are provided on the front, rear, left and right sides of the ridge 4. The position of the recess 7 is
When the packaging containers P are stacked vertically as shown in FIG. 5, by displacing the upper and lower recesses 7 so that they do not overlap with each other, the recess 7 of the packaging container on the upper side as shown in FIG. The bottom surface 7a side is set so as to be placed on the ridge 4 of the lower packaging container. Further, the depth of each recess 7 is such that when the packaging containers P are stacked one above the other, the bottom surface 2a side of the battery housing recess 2 of the upper packaging container P is inside the battery housing recess 2 of the lower packaging container P. Is fitted to the upper side of the concave portion 2 so as to prevent the battery B from coming out of the concave portion 2,
It is set so that it will not fit deeper than this.

After the battery B is accommodated in the battery accommodating concave portion 2, the packaging container P configured as described above is stacked in a vertical multistage manner as shown in FIG.

At this time, the bottom surface 7a side of the concave portion 7 of the upper side packaging container P is placed on the ridge 4 of the lower side packaging container, and the bottom surface 7a side of the battery housing concave portion 2 of the upper side packaging container P is located at the lower side. The space for accommodating the battery B in the recess 2 is ensured without deeply fitting into the battery accommodating recess 2 of the side packaging container P. Further, the inner surface of the peripheral side wall 5 of the packaging container P on the upper tier side below the recess 7 enters into the outer surface upper portion of the peripheral side wall 5 of the packaging container P on the lower tier side. As a result, the lateral displacement of the packaging containers P between the front, rear, left and right is regulated, and the stacked state is stably maintained. As shown in FIG. 4, the lateral deviation is regulated in the same way that the bottom of the groove 6 formed deeper than the battery housing recess 2 of the upper packaging container P faces that of the lower packaging container P. It is also achieved by partially entering the mouth of the groove 6.
