JPS59190837A - Processing of cap of container such as bottle - Google Patents

Abstract

PURPOSE:To manufacture large numbers of caps for containers, e.g., easy-open bottle, etc., having gas imperviousness, by a method in which the inner cylinder of a tool 10 is fitted on a pull ring 4 and positioned at the approx. center of the cap 6 by the end face 7 of the cylinder 8. CONSTITUTION:A synthetic resin cover 6 for a container, having an endless split groove 2 on its mouth wall 1, a fitting portion 3 on its inside, a pull ring 4 in the fitting portion 3, and a leg 5, is formed. Also, a tool 10 consisting of an inner cylinder 8 having a smaller diameter than the diameter of the pull ring 4 and also having an end face 7 on its tip an outer cylinder 9 formed almost concentrically with the outside of the inner cylinder 8 is formed. The cap 6 of the container is attached by fitting the pull ring 4 into the inner cylinder 8, the outside of the pull ring 4 is supported by the outer cylinder 9, and a metal foil 11 is placed on the mouth wall 1 and molded by a presser part 12 by applying heat, high frequency, or supersonic wave from the upside of the metal foil 11.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for processing the shells of containers such as bottles and cans.

Conventionally, although not shown in the drawings, an endless fissure is formed on the mouth wall of a synthetic resin bottle cap or end cap, a tear part is formed inside the fissure, and a blue hole is formed above the tear part. Those with a ring are widely used. Such bottles are prized because they have a bull ring of 7σ1 and can be easily torn to form an opening. However, such trays also have problems.

It is as follows. In other words, as mentioned above, the bottle cap is made of synthetic resin and has gas permeability. Therefore, if it is fitted over the mouth of a bottle containing a product and displayed in all stores for a long period of time, oxygen in the air will be absorbed. It may allow penetration and cause deterioration of the contents.

The inventor of this invention previously solved the problem of AM during this period, and as shown in Figs. In this figure, d indicates the fissure, e indicates the bull ring, and f indicates the outer can.

Also, by applying this, several layers of similar metal foil were applied to the synthetic resin coating on the can to prevent gas permeation. (Utility model registration filed) This invention provides a processing method for containers such as bottles that can prevent the above-mentioned gas permeation and easily process and manufacture large quantities of containers such as bottles that are extremely easy to open. It is.

Describing this invention with reference to the drawings, Figures 313 and 174
In the figure, the container is made of synthetic resin, has an endless fissure 2 on its mouth wall 1, has a tearing part 3 formed inside thereof, and a bull ring 4 is provided on the tearing part 3 with legs s5. The lid 6 is formed by an inner cylinder 8 having a diameter smaller than that of the bull ring 4 and having an end face 7 at the tip thereof, and an outer cylinder 9 formed approximately concentrically on the outside of the inner cylinder 8. A jig 10 is formed, and the lid 6 of the container (11) is attached by fitting the bull ring 4 into the inner cylinder 8, and the bull ring 4 is attached by the outer cylinder 9.
A gold maple foil 11 is placed on the mouth wall 1, and pressure is applied from the upper blade of the gold maple foil 11 by a pressure member 12 using heat, high frequency, or ultrasonic waves. This is a method for processing containers such as bottles.

In the figure, 13 is a support member, 14 is a cotton tube that is screwed together with a foreign fish (not shown), 15 is a heater, 16 is a control device that controls the temperature of the heater 15, 17 is a bottom part, and 18
Reference numeral 19 indicates a fitting portion with an outer lid (not shown), and a fitting portion 19 with a bottle (not shown).

As the gold M foil 11, an aldinium foil is used as an example, and it is also possible to use only an aluminum foil, or to use one coated with synthetic resin on one or both sides.

Alternatively, the coating may be melted and adhered.

In addition, in addition to the above [9 is 4-year-old meat, as shown in Figure 3, the law part 17
By forming the lid 6 to fit around the inner periphery of the mouth wall 1 or the outer periphery of the mouth wall 1 with some margin, the lid 6 can be prevented from swinging and can be used for positioning. Also, a type having a protrusion V as shown in Fig. 2 can be similarly processed using this apparatus. Note that although the illustrated processing member 12 uses a heater as an example, it may also use a high frequency or ultrasonic wave as described above.

This invention is constructed as described above, and the night! 410 inner cylinder 8
An outer cylinder 9 is fitted into the bull ring 4 and supports approximately the center of the bull ring 6 by its end face 7, and is formed approximately concentrically with the inner cylinder 8.
By supporting the outer OI part of the bull ring, the bull ring 4 is originally a hindrance to the inner cylinder 8, but by inserting the inner cylinder 8 into the bull ring 4 and using it, the bull ring 4 The inner cylinder 8 can be positioned approximately at the center of the lid 6 by the ring.

Therefore, the metal foil 11 can be easily layered.
