  In the tubular packaging member 70, the convex portions 71a and 71b are relatively shorter than the tubular packaging member 60 according to the fifth embodiment, and the length of the convex portions 71a and 71b is the electrode terminal 22 of the product 20. , 23. Further, the convex portions 71a and 71b have a relatively thick width as compared with the tubular packing member 60 according to the fifth embodiment. With such a configuration, it is possible to fill a gap between the tubular packing members 70 and to provide a sense of stability.

  In addition, as shown to Fig.7 (a), after assembling the tube-shaped packing member 70, it is preferable to insert the stopper 100 which has the length and width equivalent to the convex part 71a or the convex part 71b in the edge part. . Thereby, a sense of stability can be further provided.

  In the sixth embodiment, a stopper plug 80 having the same cross-sectional shape as the tubular packaging member 70 as shown in FIG. 7B may be used. Thus, the stopper rubber is buried so as to cover the entire mouth of the tube-shaped packing member 70, and the product 20 can be prevented from being pulled out or bitten.

  According to the sixth embodiment, when the two tubular packing members 70 are arranged, the convex portion 71a of one adjacent tubular packaging member 70 and the convex portion 71b of the other tubular packaging member 70 are further different from each other. Between the convex portions 71a and 71b of the tube-shaped packing member 70. In this way, the plurality of tubular packing members 70 can be integrated with a sense of stability while saving space.
