Abstract

PURPOSE:To enable smooth sealing even when there is no difference in diameter of the stopper and neck by tightening a metallic plate that covers the stopper of a container together with the neck of the container by centripetal force of a lower roller due to centrifugal force of a balance weight of a tightening device in the upper part of a supporting point that makes circular motion. CONSTITUTION:The supporting point 2 of the body 1 of a tightening device is pivoted to the end of a tightening device working range adjusting guide plate 10 mounted to a mounting frame 13 of a rotating cylinder 5, and supports the body 1 movably. The stopper 8 of the container is covered by a metallic plate 6 together with the neck of the container and a neck holder 12 can move up and down in a cylinder 5. When the cylinder 5 is rotated under this condition, centrifugal force is generated in a balance weight 3 in the upper part of a supporting point 2. Consequently, centripetal force is generated in a roller 4 at the lower end. This centripetal force acts on the plate 6 as roller pressure and deforms the plate 6 to allow smooth sealing.

Description

Detailed Description of the Invention In containers for alcoholic beverages and other beverages, after the container is KI&, the stopper and the neck of the container are covered with a lead or other deformable metal plate (hereinafter simply referred to as metal plate 5), and the stopper of the container is closed with the metal plate. It is often used to seal the neck. Conventionally, a metal plate was placed over a capped container and rotated, and most of the methods involved inserting it between rollers and pushing it into the fruit one by one to seal it.

In addition, μm O tightening pressure (hereinafter simply referred to as roller pressure)
In most cases, the adjustment of To is fixed using a spring type spring, and in many cases, only a constant roller pressure can be applied. In this way, when the p-2 pressure is constant, the company #kOg!
If there is no difference in the diameter of the container neck and the diameter of the container, problems will rarely occur.However, if there is a difference in the relationship between the two, K 13 a-'
) It was difficult to adjust the pressure.

In other words, if the roller pressure is adjusted to the diameter of the smaller diameter, the ■-R pressure will be too high and the metal plate will break at the location of the larger diameter, and conversely, if the roller pressure is adjusted to the location of the larger diameter, it will break at the location of the smaller diameter. The pressure in the recess was too weak, causing sagging and not being able to seal completely, resulting in an unattractive finish. .

The present invention provides a sealing method that does not have such drawbacks, and uses a sealing machine that is pivoted on a circularly moving fulcrum, has a balance weight on its upper part, and is equipped with a p-ra that rolls along the container neck at its lower end. Balance way F on the row 2
This method seals the stopper of the container to the neck of the container using a deformable metal plate.

The deformable metal plate in the present invention may be any metal plate conventionally used as a sealing material, such as the aforementioned lead plate, lead tin plate, or aluminum plate. Further, in the tightening machine, the circular motion of the fulcrum causes a centrifugal force to be generated on the balance weight at the upper end [4], and as a result, a centripetal force is generated on the roller at the lower end. This centripetal force acts as roller pressure. Furthermore, although the method of the present invention can provide a smooth seal even when there is no difference between the diameter of the stopper and the diameter of the container neck, it is particularly effective when there is a large difference between the two or a large step in the container neck. This shows the effectiveness of this method. In such cases, the diameter can be adjusted by attaching multiple rollers to one tightening machine, or by using multiple tightening machines and adjusting the roller positions to match the diameter of each seal part. There are many types that can seal metal plates with roller pressure suitable for sizes. That is, if the diameter of the seal portion in contact with the roller is large, the trajectory drawn by the balance weight will be small; if the diameter is small, the trajectory will be large, and a centripetal force, that is, roller pressure suitable for the normal pressure seal portion, will be obtained. Therefore, there is an advantage that there is no need to individually adjust the roller pressure. Furthermore, when a roller that tightens a small diameter area is brought into contact with a small diameter area, it may be necessary to pass through a large diameter area and contact the small diameter area. In this case as well, when the roller passes through a large diameter area, the centripetal force is weak, and the roller 2 pressure during passing is small and has the effect of not damaging the metal plate. Detailed description of the invention.

Fig. 1 shows the movement of the roller when the diameter of the part that the roller touches is large, 21M shows the case that the diameter of the part that the roller touches is small, and 4' is a small roller. Figure 31 is! This is a perspective view of the main part of the side of FIG. 2, and the role of the large roller 4#i is to seal the neck of the bottle, and the role of the small roller 4' is to seal the groove between the stopper and the mouth of the bottle. The rows 24 and 4' are installed at different heights. It is directly attached to the Row 24Fi tightening machine, and the roller is a trap so that it can rotate freely.As mentioned earlier, if the diameter of the part that the roller 4 touches is large, the centripetal force is weak, and if the diameter is small, the centripetal force is strong. It looks like this.

On the other hand, the small roller 4' partially acts on the stepped portion as shown in Figure 5, and the mounting force is movably attached to the shaft of the row 24 and is controlled by the roller pressure adjustment screw 15. By adjusting the strength of the spring 14, the necessary low 2 pressure is obtained, and the spring operates independently of the movement of the 0 low 24Fi roller 4, which plays the role of escape, depending on the size of the bottle diameter.゛Figure 4 is an overall perspective view of three tightening machines arranged radially around a rotating cylinder. 4 is a large roller adjusted to a different height from 4. As shown in the figure, it is suitable for use when creating a step between the stopper and the container neck, and when the container neck is leveled. At the end of the movement, the metal plate fits perfectly on the stopper and bottle neck, creating a beautiful finish.

As described above, even when there is a step between the container stopper and the container neck, or when there is a step in the container neck, the present invention applies positive roller pressure appropriate to each diameter to prevent breakage or sagging of the metal plate. It has the characteristics of being completely cool without any problems and having a beautiful finish. −
