Description

DETAILED DESCRIPTION OF THE INVENTION The present invention utilizes the negative value of a bottomed cylindrical body for containers made of sweet acid llIr film as a raw material. [Cylinder made from 1 film? ! - is general-purpose as a simple packaging container for food products, #l goods, etc. The mouthpiece of this type of general container is curl II (layered processing) 7-n4 in order to maintain its shape.・However, conventionally, the first method is to manufacture a cylindrical valley as shown in FIG.
1IIt, e.g. cut into plow-shape π thermoplastic sweet acid 11
1, roll a sheet R into a cylindrical shape, heat bond the overlapping sides to each other to form a cylindrical body, and then bend the bottom @r in a circular direction to form a bent groove U), or In a soft theory, the base plate (mmV) is heated and bent at a right angle to form a cylindrical body with π, and then the bottom plate (inserting E4r and the above-mentioned heated pot) L is heat-bonded to the inside of the plate. Since it is one V and π, the Izut field is also 5its mouth curl-4-1r%g, another processing process is required, Vh l & Vh - mercenary of manufacturing process and glands. -Soaring prices were unavoidable, so I added #.

The 4-way ac II Mimoto-Hatsumari is formed by an appropriate means to form a π cylindrical body, and the bottom side 11[sK, as described above, is the π base IN'! By forming the desired curlic acid ('i k 1ifj &fF) in the curve formation (a) and other (-rho) for the # meeting, it is possible to eliminate the Ill miscellaneous effects on the acid progression of this type of container in the past. It is solved by all properties and is π.

Hereinafter, detailed description will be given based on an embodiment Vt of one component pipe of the present invention. Figure 2 shows a curling device used for carrying out the method of the present invention, 1 is the previously described π-shaped Ig4 shield 311c.
A cylindrical body is formed one after another from the material, and 2 is a holder that horizontally supports the cylindrical body, and its surface is.

For example, friction*
sI! The case should be constructed of high quality materials.

In addition, 3 and 3' are appropriate heaters 1 installed and π left and right V metal fields, and Il! Reference numerals 4 and 4' indicate brackets 1 which movably support the Jokikin mV in a movable manner.

In addition, the opposing actuation ambiguity S of (1) 4.4' in the present invention may be particularly constant V, for example, over mtJ [#61! 1 opposite screw S/, S# on the 50th side of the rotating ring connected to the
I-#lA or wrinkle bracket 4゜4'
It may also be connected to a hydraulic or pneumatic cylinder (not shown).

Therefore, each inner surface of the upper metal a13.3' is shown in FIG.
Although there are some differences in shape due to the four-fold image and the force Il, the size t in the cross section of the cylindrical body 1 in each case is
! L, and slopes 3m and 3'a in the dormitory where the 10% open end of the cylindrical body is introduced near the local slope.

This flK4- imaginary part 3 bs 3't' sAlso, the escape oblique directions 3a and 3'alr, which spread in a circular direction from the groove part, are n.
One end (bottom side) of the cylindrical body, which is buried and heat-pressed to the same W# at both sides, is bent inward by about 90 degrees to form a π layer III-VI). In addition, the n pi curl (c) is formed once with a constant curvature, each having an n core.

In addition, both ends of 1 cylindrical body @ L J? As mentioned above, the changes in the amount of bending in the upper period are as follows:
b and relief Ii + the difference in shape of surfaces 3a and 3'a, and the difference in %5SV of the cylindrical body - the softening temperature of the metal, which is 41%.

1 Kasumi In this situation, both end bending component molecules of the above cylinder must be 1lIF
By preheating the mold and filling air (with a pressure of IIxI) from at least one side of the mold, it is possible to not only form curl ruts more effectively, but also to In particular, it is possible to detect defective products at an early stage by checking the presence or absence of mz at the seam portion of the cylindrical body, especially in the case of a sharpening number.

It is still the same as before that the π double-curved cylinder thus obtained is formed into a bottomed cylinder as shown in FIG. be.

In addition to the π embodiment described above, when forming outward curl tubes at both ends of a cylindrical body,
b * Sandwiched and buried 1e plan circular diagonal 3"s 3- and escape diagonal 3c, s'at-pupil change to the outside of the circle π mold rjll!
All you need is a tool.

According to the method of the present invention, the curves at both ends of the cylindrical body, which have been molded in one separate piece, can be replaced with the same #fK formed in one process. The single structure of the seed cylindrical container is simple and easy to use, and it can also be used as a replacement for the conventional cylindrical container.
It improves E efficiency and lower cost, so we are looking forward to the Sat effect and effect.

Claims (1)

[Scope of Claims] 1. In a method for manufacturing a cylindrical container made of a heat-resistant synthetic acid film, a cylindrical body held horizontally is sandwiched between fLπ cylinders r, and each circular surface is provided with a guide NM direction, a groove portion and a beveled end. Two pieces of gold Ill'9I arranged in a ring are simultaneously actuated to face each other, and one end of the cylindrical body forms a nine-bent formation, and the other end forms a curled arm, respectively, forming a π-dominant and an upper-bent formation.
