BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below. 1 to 4, reference numeral 1 denotes a packaging body formed by packaging a cylindrical dry battery 3 as an article to be packaged, which includes a mount 4 as a base plate and a packaging material 2.

On the upper surface of the mount 4, descriptive texts are appropriately written, and a pair of upper and lower cut-and-raised pieces 5a, 5b are further formed. That is, although the cut-and-raised pieces 5a and 5b are formed by cutting the mount 4, the locking portion 6 having the taper portion 6a whose width becomes narrower toward the base, and the locking portion 6 It is composed of a projecting portion 8 that is projected forward through the fold line 7.

When forming the cut-and-raised pieces 5a and 5b, as shown in FIG.
In the upper cut-and-raised piece 5a, the protruding portion 8 is located below the locking portion 6, and conversely, in the lower cut-and-raised piece 5b, the protruding portion 8 is located above. Cut in. The width W and the projection length L of the protrusion 8 in the left-right direction are set to be substantially equal to the diameter thereof so that the upper surface and the lower surface of the dry battery 3 can be completely covered, and the tip of the protrusion 8 is circular. It is formed in an arc shape. Further, the distance L1 between the both protruding portions 8 protruding forward is substantially equal to the length of the dry battery 3 as shown in FIG.

The packaging material 2 is formed of a heat-shrinkable polyvinyl chloride or polyester film in a tubular shape, and shrinks in the circumferential direction to reduce the diameter, but hardly shrinks in the upper and lower longitudinal directions. . One dry battery 3 is inserted into the packaging material 2, and the upper end 11 and the lower end 12 of the packaging material 2 are inserted and locked between the mount 4 and the locking portions 6 of the cut and raised pieces 5a and 5b. .

The entire packaging material 2 is heat-shrinked,
The packaging material 2 covers the dry battery 3 in a state where the upper end 11 and the lower end 12 thereof are bent and adhere to the peripheral edge of the projecting portion 8 due to thermal contraction. Incidentally, 4a is a locking hole formed on the top of the mount 4.

The packaging body of the present embodiment has the above-described structure. Next, the case of manufacturing the packaging body 1 will be described. First, both cut and raised pieces 5a and 5b are floated in front of the mount 4, The projecting portion 8 is bent substantially horizontally, and the upper end portion 11 of the packaging material 2 in which the dry battery 3 is inserted is inserted from below between the locking portion 6 of the upper cut-and-raised piece 5a and the mount 4. Bottom edge
12 is inserted from above between the locking portion 6 of the lower cut and raised piece 5b and the mount 4.

Next, when the packaging material 2 is heated, the packaging material 2 contracts in its circumferential direction, so that the upper end 11 and the lower end 12 are
It contracts so as to bite into the locking portion 6, and the upper end portion 11 and the lower end portion 12 contract toward the inside along the tapered locking portion 6 and the protruding portion 8, so that the upper end portion 11 and the lower end portion 12 can be easily The upper surface and the lower surface of the dry battery 3 can be closed by the upper and lower projections 8 and the peripheral surface of the packaging material 2 can be bent and adhered to the upper surface of the upper projection 8 and the lower surface of the lower projection 8.
Will be covered by.

The upper end of the packaging material 2 that is in close contact with the dry battery 3
Since the 11 and the lower end portion 12 contract along the tapered portion 6a of each locking portion 6 and are in close contact with the upper and lower protruding portions 8, it is difficult to separate from the locking portion 6 and the dry battery 3 is removed. It can be firmly held on the mount 4.

Moreover, since the upper and lower surfaces of the dry battery 3 are closed by the upper and lower protrusions 8 and the peripheral surface is covered with the packaging material 2, impurities such as dust may be directly accumulated on the upper surface of the dry battery 3. Needless to say, there is no possibility of entering the packaging material 2. Furthermore, both protrusions 8 also have a function of protecting both terminals of the dry battery 3.

The present invention is not limited to the above embodiment, but it is also possible to integrally package a plurality of dry batteries 3 as shown in FIG. When packaging a plurality of dry batteries 3 as in this embodiment, or when packaging a large diameter dry battery 3 even by itself, by bonding the packaging material 2 to the mount 4 side with an adhesive, The holding may be made stronger.

In each of the above embodiments, the cut-and-raised pieces 5a and 5b are provided both above and below the dry battery 3, but the cut-and-raised pieces can be provided only above the dry battery 3, and in such a case. Holds the lower surface of the dry battery 3 by the bent lower end 12 of the packaging material 2.

Further, the shape of the cut-and-raised pieces 5a, 5b can be arbitrarily set, and the protrusion 8 does not necessarily have to be provided with a size that covers the entire upper surface or the lower surface of the dry battery 3, and the protruding portion 8 has a size larger than the diameter of the dry battery 3. Even if the packaging material 2 is slightly small, the upper end portion and the lower end portion of the packaging material 2 may be bent to the protruding portion 8.

Moreover, the article to be packaged is not limited to the dry battery 3, but a container having any shape such as cosmetics such as lipstick, medicine, stationery or the like can be adopted, and depending on the shape of the article to be packaged. The cut-and-raised pieces 5a and 5b can also be set in different shapes.

[0020]

As described above, in the present invention, the cut-and-raised piece is provided with the engaging portion into which the upper end of the packaging material is inserted from below and the projecting portion which projects above and forward of the article to be packaged,
Since the upper end portion of the packaging material is bent and formed on the upper surface of the projecting portion, the upper surface of the article to be packaged can be covered by the projecting portion, and dust or the like is prevented from directly collecting on the upper surface of the article to be packaged. There is an advantage that you can.

Moreover, when the locking portion is formed so that the width thereof becomes narrower toward the base side, it becomes difficult for the packaging material to separate from the locking portion, and the article to be packaged is firmly fixed to the base plate. In addition, the upper end portion of the packaging material can be easily bent toward the protruding portion when the packaging material contracts, and the packaging state becomes good.
