Problems solved by technology

However, at this time, a series of complex devices for controlling the position of the nozzle are required during the vacuum sealing process and the heat sealing process
[0008] There is another conventional device for vacuum sealing plastic bags, in which the part of the bag located in front of the nozzle is heat-sealed, but in this case, the nozzle is placed in the opening part of the bag, making it possible to form a Localized air traps, which of course make a good seal in plastic bags difficult
And there is also a problem that the length of the plastic bag corresponding to the depth of the nozzle inserted into the inside of the plastic bag is unnecessarily wasted

Embodiment Construction

[0023] Now, explanations of preferred embodiments of the present invention will be given below.

[0024] Figures 2 to 4 A spout 10 for vacuum sealing plastic bags according to the invention is shown. The nozzle 10 of the present invention includes an embossed portion 11 and a plurality of break lines 16 and is made of a heat-sealable material in a form that can be inserted into a plastic bag 20 (such as Image 6 ) is made, thus forming a passage 12 for exhaust from the plastic bag 20. After this vacuuming step, the nozzle 10 and the plastic bag 20 are heat-sealed together by operating a heat-sealing portion 24 .

[0025] The nozzle 10 is sufficiently long, but it can be easily severed at the breaking line 16 if necessary, as will be discussed later.

[0026] The shape of the embossed portion 11 on the inner peripheral surface 14 of the nozzle 10 is concavo-convex, so that the exhaust passage 12 is continuously formed along the length direction of the nozzle 10 . On the ot...

Abstract

Disclosed is a nozzle for vacuum sealing a plastic bag, the nozzle includes an embossing part formed on the peripheral surface of the nozzle, so that air discharging passages are formed on the peripheral surface of the nozzle; and a plurality of break lines formed at predetermined regular intervals on the outer peripheral surface of the nozzle, for cutting the nozzle to a predetermined length, wherein the nozzle is made of a heat sealable material, so that the nozzle cut by the break line is inserted into the plastic bag and heat sealed together with the plastic bag.

Description

technical field [0001] The present invention relates to a nozzle for vacuum sealing a plastic bag in which items such as stored food are placed, the nozzle is inserted into the plastic bag to form an exhaust passage, and the nozzle and the plastic bag are heat-sealed together , and the nozzle has a plurality of break lines on its outer peripheral surface. Background technique [0002] Generally, the plastic bag in which the stored food is placed is vacuumed and sealed by a vacuum seal to keep the food fresh. [0003] A prior art is disclosed in Korean Patent Publication No. 92-0700998 entitled "An apparatus for vacuumsealing plastic bags", which is shown in figure 1 a. The conventional plastic bag 21 has an embossed portion 25 formed on its inner surface so as to serve as a vent passage when the plastic bag is sealed. by using the figure 1 The device 20 of b and the plastic bag 21 is evacuated and heat-sealed. [0004] In more detail, the conventional device 20 for vacu...
