Abstract

PROBLEM TO BE SOLVED: To improve heat sealability, separability and economical efficiency for a synthetic resin container. SOLUTION: Twilled sealing and linear sealing are executed simultaneously for a synthetic resin container by employing a heat seal plate made up by fitting a plate body 3 having a linear sealing surface 3a into a fitting cavity 2b of a plate body 2 having a twilled sealing surface 2a and combining both of the plate bodies together. A twilled sealing part formed by the twilled sealing surface 2a is weak in sealing strength and is generally accommodative to easy separation for unsealing the synthetic resin container, and is available for protecting a linear sealing part formed by the linear sealing surface 3a. Sealing work can be completed by a single operation with a single sealing device.

Description of the Related Art When a synthetic resin packaging container is filled with contents and sealed with a lid material, a heat-sealing method is usually used, but a flat sealing blade type is generally used. In addition, a twill seal may be provided so that the contents can be easily opened for taking out the contents after sealing. When filling a synthetic resin container with a liquid, for example, water, the content of the content is exuded to the outside through the twill seal, although the peelability is sufficient when the twill seal is used. There is. Therefore, a method of preventing the exudation of the liquid is taken by using a wide seal with a flat seal blade die, but the easy peeling property is not sufficient, and the twill seal and the line seal should be used together. Is being carried out.

法を提供するものである。Conventionally, since the line seal and the twill seal are separately performed twice, the gap between the two seals is not constant, and in some cases, the twill seal part and the line seal part are separated from each other. In addition to overlapping, it is difficult to ensure easy peelability, and the filled synthetic resin container lacks the beauty. The present invention has been made in view of such circumstances, and the line seal prevents the liquid in the content filled in the synthetic resin container from leaching to the outside, and ensures easy peeling by the twill seal. By using a heat-sealing plate having a line seal surface and a twill seal surface which are formed on the same plane with a predetermined gap therebetween, the twill seal and the line seal can be kept at a constant gap for sealing. The present invention provides a method for heat-sealing a synthetic resin container having a good finished state.

In order to achieve this purpose, the width A of the twill seal surface 2a is
And the height is set. Also, the width B of the line sealing surface 3a
Is set so that the vapor of the effluent escapes laterally without remaining in the line seal portion Sc and has a predetermined sealing property and sealing strength. Further, the intervals C and D form a vapor escape space, and have a size capable of sufficiently absorbing the vapor generated in the surroundings.

Although the heat seal plate 1 shown in the drawing has two chamfers, it may have one face or three or more faces. Further, although two line sealing surfaces 3a are provided in the figure, one line or three or more lines may be provided. In some cases, a twill seal surface can be formed inside the line seal surface.

同時に行う。When a synthetic resin container is heat-sealed, the heat-sealing plate 1 having the above-mentioned structure is used as follows. That is, taking the case of packaging the quail eggs T as an example, the synthetic resin container body HS and the synthetic resin lid member FS.
The quail eggs T from the shell are put into the recesses HSa and FSa of the shell and placed on the heat seal plate 1 in the same manner as in the conventional case, and the twill seal surface 2a and the line seal surface 3a simultaneously perform the twill seal and the line seal. .

はなく他の物を包装することもできる。At this time, if the white of the egg T or the like flows between the synthetic resin container main body HS and the lid member FS in the sealing portion, it will evaporate due to the heating during the heat sealing to become steam. ,
In the twill seal part, it escapes laterally from the minute gaps in the twill seal, and in the line seal part, the width B of the line seal face 3a is narrowed so that this also escapes laterally. It does not have a bad influence by staying in. Therefore, the synthetic resin container is always heat-sealed in a predetermined state without being affected by the outflow of white meat or the like. Since there are two line seal portions Sc, the sealing property is good. The item to be packaged is not limited to quail eggs and other items can be packaged.

The heat-sealing portion is peeled off by pulling the peripheral portions of the synthetic resin container main body HS and the lid member FS up and down, but the sealing strength of the twill seal portion Sb that is first peeled is due to the surface shape of the twill seal surface 2a. Since it is not so strong, the synthetic resin container body HS
Even if the lid member FS has no margin in the peripheral portion of the lid member FS that is not heat-sealed and it is difficult to pinch it, it can be easily peeled off. Further, although there are two line seal parts Sc to be peeled off next time to enhance the sealing property, the width is narrow, and the peeling of the twill seal part Sb ensures that the synthetic resin container main body HS and the lid member FS are firmly attached. Since it can be pinched, this part can be peeled off relatively easily. Therefore, the article to be packaged T can be easily taken out from the synthetic resin container without any trouble.

If necessary, heat seal in a separate process. Both or either one of the twill seal surface 2a and the line seal surface 3a can be closed.

いという効果がある。As described above, the heat sealing plate according to the first aspect has a structure in which the line sealing surface and the twill sealing surface are formed so as to be close to each other on the same plane and maintain a predetermined distance. Further, the heat sealing method for a synthetic resin container according to claim 2 uses the heat sealing plate according to claim 1 to heat seal the synthetic resin lid member to the synthetic resin container body,
Since the line seal part and the twill seal part are formed at the same time, the time required for the line seal and the twill seal can be minimized in one operation, and the twill seal and the line seal can be arranged at a constant interval. It can be held efficiently and easily peeled off, and can be performed efficiently and beautifully. Further, since only one sealing device is required, it is economical and there is an effect that a large space is not required for installation.
