ーパック形式が強く要望されて来ている。Conventionally, in a blister pack type packaging, a molded front member and a back member are welded or bonded at a joint portion, a so-called flange portion, to form a blister pack, or the flange portion of the back member is bent, There is a slide blister type in which a flange portion of a front member is inserted. However, recently, there has been a strong demand for a blister pack type in which the width of the flange portion of the welded or bonded portion is as small as possible and the sealing property is good.

いる。As a method of welding or bonding the front member and the back member at the flange portion, a method of welding by heat sealing and a method of bonding using an adhesive have been adopted. The method according to these methods is divided into a welding or bonding step and a step of punching with a blade while leaving a part of the joint, and the precision control in the step of punching with a punching blade must be strictly controlled. Is becoming more time-consuming.

である。In other methods, recently, using a high frequency, a method of fusing simultaneously with welding has been proposed.However, the method using this high frequency is welding using a blade-shaped electrode, and fusing, Sparks are likely to occur at the time of welding and fusing.Each time, the cutting edge must be cleaned, which is dangerous, and at the same time, the welding, the finish of the welded section is poor,
In addition, at present, a product having a stable sealing property has not been obtained.

It is to propose a method for producing a blister pack that can be opened.

完成させたものである。The present invention, in a blister pack, as a result of repeatedly examining the method of welding the molded front member and back member by ultrasonic waves and fusing, the blade shape of the ultrasonic horn on the pedestal side is made into a single blade shape, The ratio T / t of the thickness T of the blade-shaped portion to the thickness t of the bonding portion has a blade-shaped shape in the range of 0.5 to 10, and the blade-shaped shape is directed toward a portion to be blown from a portion to be bonded. has a gentle tapered or curved shape Te, further, with respect to the cradle of the cutting edge height t 1 is t, and had have a first cradle becomes t> t 1, welding by ultrasound, blown It has been found that the simultaneous execution of the above is the most excellent method, and the present invention has been completed.

望ましい。The blade shape of the receiving portion of the ultrasonic horn used in the present invention needs to be the blade shape shown in FIG. 4, and the tapered blade shape shown in FIG. The shape is desirably a shape having an angle of 10 to 60 degrees toward the cutting edge, and in the shape shown in FIG. 4 (b), about 0 to 30 degrees toward the cutting edge. It is desirable to have a curved shape having an angle and rising gradually and reaching the cutting edge.

低下させてしまう。Also, the thickness T of the cradle affects the width of the surface to be welded, and if the width is too large, it is not possible to obtain the initially desired minimum welding surface width, and if it is too small,
It is not possible to obtain sufficient welding strength,
It is important that the ratio (T / t) to the total thickness t of the front and back members at the joint surface is 0.5 to 10. When T / t is 0.5 or less, sufficient welding strength cannot be obtained, and the strength of the blade-shaped cradle is also weakened, which may result in breakage. If T / t is 10 or more, the width of the flange at the welded portion becomes large and the commercial value is reduced.

る。According to the blister pack obtained by the present invention, the protrusion of the joint (flange) can be made extremely small, the commercial value can be increased, welding and fusing can be performed simultaneously in one step, and furthermore, the care of the cutting edge can be achieved. In addition to being able to make it very easy, for example, even when dirt such as water droplets, oil droplets, etc. on the joint portion, and solid dirt is slightly adhered, by applying ultrasonic vibration, Can be removed, and a very stable and complete sealing property can be obtained.
