ク性を有したラベル外装体が多く使用されている。BACKGROUND OF THE INVENTION In recent years, with the advancement of ICs, LSIs, and other conductors, the field of application of batteries has been significantly expanding as main power sources for consumer and industrial equipment, or as memory backup power sources. Particularly in the field of consumer equipment, the demand for power supplies for portable power sources such as radio cassettes for cameras is increasing. However, there is a strong demand from the user side to reduce the frequency of battery replacement, and from the manufacturer side, there is an urgent need to increase the capacity and extend the lifespan of batteries. In general, the shape of the ML pond (outer diameter - height) is standardized by JIS or Ill standards, and the design of the battery compartment of the equipment used is also based on this standard. In order to achieve this, within a certain volume,
The main focus of development was how much active material could be packed into the pond. Based on this point of view, efforts have recently been made to reduce the volume occupied by the battery outer casing and fill the volume with one battery active material. In accordance with the above-mentioned principle, label packagings having shrink properties and tank properties are now often used as battery packagings.

が多々あった。Problems to be Solved by the Invention Methods for stamping the manufacturing date of a battery on the aforementioned exterior label with shrink properties and tank properties can be roughly divided into (1) a method of stamping with printing ink? ) There are two methods: hot stamping (3) stamping. However, in (1), printing ink is used, so there is no staining due to ink adhering to the label, and the use of solvents, etc. It is necessary to install auxiliary equipment in the work environment, and in the case of method (2), the equipment is expensive and the printing may become unclear because the pressing force varies depending on the shape of the characters. be. On the other hand, the method (3) is effective because the equipment cost is low and there is no staining due to ink adhering to the label, but it uses an outer label that has shrink and tank properties as the outer body as in recent years. In this case, when a stamped item was left under high temperature, the stamp often disappeared due to the shrinkage of the label exterior.
本発明は前記問題点を解決する捺印方法を提供するもの
である。The present invention provides a stamping method that solves the above problems.
課題を解決するための手段
本発明は、あらかじめラベルの捺印部分を、ラベルの収

押圧して加熱収縮させ、その後前記押圧部に製造日を示
すロット記号を刻印によりて印字するものである。Means for Solving the Problems In the present invention, the stamped part of the label is pressed in advance with a jig whose temperature is set to 20 to 50'C higher than the shrinkage temperature of the label to heat shrink it, and then the stamped part of the label is heated and contracted. A lot symbol indicating the date is printed by stamping.

、鮮明にロット捺印が残るものである。First, the lot stamping area is pre-shrinked at a temperature 20 to 60°C higher than the shrinkage temperature of the label material, so even if the battery becomes hot due to a short circuit, the lot stamping area will shrink even more. Since this phenomenon does not occur, the lot stamp remains clearly.

。Examples Examples will be described below. FIG. 1 shows a battery 2 using a label according to the present invention, such as a primary battery such as a lithium battery, an alkaline battery, or a manganese battery, or a secondary battery such as a nickel-cadmium battery, a silver storage battery, or a ship storage battery. Label materials for this battery include polyethylene, polypropylene, polyester, polyimide,
Use heat-shrinkable films made of polyvinyl chloride, polyvinylidene chloride resin, etc. alone or in combination, and place acrylic, ester, or rubber-based shelf materials on one side of these films. It has sex. Next, to explain the stamping method, the stamping part 3 of the label should be of the same size as the stamping part 3, and 2 times higher than the heat shrinkage temperature of the label material.
The label material is pressed with a jig heated to a temperature of 0 to 50'C, and the stamped area is heated and shrunk in advance, and then the production lot number is stamped and suppressed.

るためである。The label material thus prepared is wrapped around the side surface of a battery, and the upper end 1a and lower end 1b of the label are heat-shrinked using a hot gun or a heater to form a battery. The temperature of the jig that heats the stamped part of the label was set 20 to 50°C higher than the shrinkage temperature of the label at 60°.
This is because in cases of C or higher, the label material itself shrinks too much and its material strength becomes brittle, causing the label to tear when stamped. On the other hand, if the temperature is below 20° C., the shrinkage will not be sufficient, and when the battery is stored at high temperatures, the stamped area will also shrink further, making the first lot stamp unclear.
