性を発揮し得ないという不都合があった。2. Description of the Related Art Conventionally, as this type of annular packing, a high density paper of about 1.0 g / cm 3 impregnated with a water-repellent substance such as paraffin wax and punched into an annular shape has been widely used. However, this not only has a low cushioning property as an annular packing, but the impregnated amount of the water-repellent substance is naturally limited because it is a high density paper,
When applied to a manganese dry battery, there is a disadvantage that sufficient leakage resistance cannot always be exhibited.

法（以下「改良法」と称する。）が提案されている（実
公平５−７７３１号公報参照）。Therefore, 40% by weight of a water-repellent substance composed of a mixture of polybutene, paraffin wax and polyethylene is used for a paper material such as absorbent paper having a density of 0.5 to 0.6 g / cm 3.
A method (hereinafter referred to as "improvement method") for improving the leakage resistance of a manganese dry battery by using the impregnated material as a ring packing has been proposed (see Japanese Utility Model Publication No. 5-7731). .

十分であると言わざるを得ない。By the way, in this improved method, the impregnation rate of the water-repellent substance must be maintained at 40% by weight or more in order to improve the leakage resistance of the manganese dry battery. Management is very important. Even if it has been confirmed that if the impregnation rate of the water-repellent substance is 40% by weight or more, the excellent liquid leakage resistance is confirmed, a method to actually maintain the impregnation rate of the water-repellent substance to 40% by weight or more has been found. Unless it is issued, it must be said that the improved method has technical value but insufficient industrial value.

る。That is, the present invention has a bottomed cylindrical zinc can (1), and a negative electrode terminal plate (10) and an annular packing (11) are sequentially arranged at the bottom of the zinc can. The heat-shrinkable resin tube (9) is wound around the outer circumference of the zinc can in such a manner that the peripheral portion of the heat-shrinkable resin tube covers the annular packing, and the outer can (12) is further wound around the outer circumference of the heat-shrinkable resin tube. When manufacturing the annular packing in a manganese dry battery, the ends of which are attached by clamping the negative electrode terminal plate and the annular packing through the heat-shrinkable resin tube, a density of 0.5 to 0. 6 g
The water content is 4 after drying the paper material with air permeability of 6 to 10 seconds at / cm 3.
%, And in this state, the paper material is impregnated with 40% by weight or more of a water-repellent substance made of a mixture of polybutene, paraffin wax and polyethylene. Further, the mixing ratio of the polybutene and the paraffin wax is 10:90 to 5 by weight.
The mixing ratio is in the range of 0:50, and the mixing ratio of the polyethylene to the polybutene is 3 to 8% by weight.

である。Here, the density of the paper material is 0.5 to 0.6 g /
The limitation to cm 3 is that if the density of the paper material is less than 0.5 g / cm 3 , the hardness of the paper material will be insufficient and the punchability and handleability will deteriorate, resulting in work difficulties. This is because when the density of the paper material exceeds 0.6 g / cm 3 , the absolute impregnation amount of the water-repellent substance becomes too small to impregnate the required amount.

A paper material such as absorbent paper having an air permeability of 7.5 seconds at 5 g / cm 3 is prepared and dried for 80 seconds in a hot air dryer at 192 ° C. to reduce the water content of the paper material to 4% or less. Next, the paper material is placed in a container in which a water repellent substance made of a mixture of polybutene, paraffin wax and polyethylene is stored for 12 seconds to impregnate the water repellent substance. Then, the impregnation rate of the water-repellent substance becomes 40% by weight or more. Next, this paper material is punched with a die to form an annular packing 11.

結果をまとめて図２に示す。In order to confirm the above-mentioned effect, it was investigated how the impregnation rate of the water-repellent substance changes when the air permeability and the water content of the paper material are changed. That is, density 0.55 g / cm
Prepared several kinds of paper materials whose air permeability was appropriately set within the range of 6 to 14 seconds in 3 , and changed the drying conditions for each so that the water content was 4%, 6% and 8%. . The impregnation rate of the water-repellent substance was measured for these paper materials. The results are summarized in FIG.

られる。As is apparent from FIG. 2, in the paper material having each water content, the impregnation rate of the water repellent substance decreases as the air permeability increases. In addition, in the paper material of each air permeability, when the water content increases, the impregnation rate of the water-repellent substance decreases, and the variation in the impregnation rate also increases. When the air permeability is 6 to 10 seconds and the water content is 4%, the target impregnation rate is 40% by weight.
The above is achieved, and the variation in the impregnation rate is small. This is because the water content of the paper material before the impregnation is kept low, so that the water-repellent substance is better wetted to the wood fibers constituting the paper material and the impregnation speed is increased, It is considered that the cause is that the occurrence is suppressed.
