Description

[0001] Pouch type packing container [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pouch-type packaging container, and more particularly, to a pouch-type packaging container in which contents are hygienically stored and easily discharged to the outside.

In recent years, contents such as liquid or gel type foods, cosmetics, household goods, and the like are housed and packed in disposable pouch-type packaging containers. Particularly, the pouch-type packaging containers are folded in half so that the contents are discharged to the outside by the folding pressure. Is widely used.

For example, in Japanese Patent No. 10-1597150 (a liquid sheet pouch packaging material to which a laser cut is applied), a flexible upper film and a lower-quality lower sheet are bonded together by heat sealing, and the contents are sealed Wherein the lower sheet has a three-layer structure consisting of an adhesive layer, a protective layer and a base layer sequentially from the top, and the adhesive layer and the base layer of the lower sheet are laminated by laser beams And the guide lines are formed at predetermined depths.

Accordingly, when the curvature of the guide line exceeds a critical angle when the liquid-phase sheet pouch-type packing material is bent, the protective layer and the guide line are simultaneously broken and the discharge port is opened.

However, in the conventional structure, a guide line is formed by burning the adhesive layer by the laser beam in the adhesive layer in contact with the contents. Dust is generated at the time of forming the guide line, so that the adhesive layer is buried in the adhesive layer. Contamination of the contents occurs because the contents and the dust on the adhesive layer are mixed with each other.

This results in very unsanitary results, and the dust generated when the film material is burned is very harmful to the human body.

In addition, since the guiding line is formed at the same position of the base layer and the adhesive layer by the laser beam, the contents are protected by the very thin barrier layer, thereby easily breaking the barrier layer during the flow, resulting in leakage of contents.

Accordingly, the present invention has been made in view of the above problems, and it is therefore an object of the present invention to provide a pouch for preventing the generation of dust, Type packaging container.

According to an aspect of the present invention, there is provided a pouch-

A soft top film is placed on the upper part of the lower quality sheet of the radial quality and a thermocompression part which is thermocompression bonded with a predetermined width along the edge of the lower sheet and the upper film is formed, In the container,

A groove extending outwardly from the accommodation space in a groove shape;

And a discharging portion thermocompression-bonded by heat and pressure higher than other portions of the thermocompression bonding portion from the outward direction distal end portion of the groove portion to the outer circumferential portion of the packaging container.

According to the present invention, when the lower sheet and the upper film are adhered to each other, the thermocompression bonding strength is adjusted to form the discharging site, so that harmful dust generated when the guide line is formed by laser processing is not generated, In addition, the discharging portion is not easily released, so that the contents are prevented from being leaked during circulation.

1 is a view showing the structure of a pouch-type packaging container of the present invention.
2 is a view showing another embodiment of the present invention.
3 is a cross-sectional view of a portion where a discharge portion is formed;

The present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a view showing the structure of a pouch-type packaging container 100 of the present invention. The upper film 120 is placed on the upper side of a rectangular sheet-like lower sheet 110 having a thickness of 250 to 450 μm And the edge portions thereof are thermally bonded by the thermocompression bonding portion 130 to form a receiving space 101 therein. The receiving space 101 accommodates liquid or gel type food, cosmetics, household goods, and the like.

The upper sheet 120 may be a PE film having a thickness of about 80 占 퐉.

The discharging unit 140 is formed on one side of the thermocompression bonding unit 130 to discharge the contents contained in the accommodating space 101 to the outside. Heat and pressure.

The discharging unit 140 is formed at a transversely middle portion of the packaging container 100 formed by thermally pressing the lower sheet 110 and the upper film 120. The discharging unit 140 removes from the accommodating space 101 the packaging container 100 And the extending end of the groove 141 does not come into contact with the outer portion of the marking container 100.

The groove portion 141 extends from the accommodation space 101 so as to have a width of about 1/2 to 1/3 with respect to the width direction of the thermocompression bonding portion 130.

A discharge portion 142 formed by a compression heat and a compression force different from that of the thermocompression bonding portion 130 is formed from the tip of the groove portion 141 to the outline of the packaging container 100. The compression portion of the discharge portion 142 The pressing force is formed to be larger than that of the thermocompression bonding portion 130.

For example, if the thermo-compression bonding part 130 thermally bonds the lower sheet 110 and the upper film 120 with a compression heat of 180 ° C. and a compression force of 5 kg / The thermal bonding is carried out at a compression heat of 189 to 198 ° C, which is increased by 5 to 10%, and a compression force of 5.5 to 6 kg / cm 2, which is increased by 10 to 20%.

Therefore, the upper film 120 at the discharging portion 142 is thinly joined to the thermocompression bonding portion 130 because the elongation is increased.

3, the upper film 120 is stretched to be thinner than other portions of the thermocompression bonding portion 130 by the compression heat and the pressing force, It can be exploded.

Therefore, when the packaging container 100 is folded in the lateral direction of the portion where the discharging portion 140 is formed, the pressure in the receiving space 101 is increased. This pressure is concentrated in the discharging portion 142 is beyond the critical pressure, the discharging portion 142 is discharged and the contents are discharged to the outside.

Of course, only the discharging portion 142 can be formed without the groove portion 141. In this case, the discharge portion 142 thinly joined by the internal pressure of the receiving space 101 may be blown out to discharge the contents .

A pressure regulating part 143 is formed in the accommodation space 101 adjacent to the inside of the groove 141 or the groove 141 to form a point where the lower sheet 110 and the upper film 120 are joined. The pressure regulating portion 143 disperses the pressure applied to the groove portion 141 so that the discharging portion 142 does not easily burst.

That is, if the pressure is greatly applied to the discharge portion 142 due to an external force or the like during circulation, the discharge portion 142 may easily burst, but the pressure is controlled by the pressure regulating portion 143 to be applied to the discharge portion 142 When the packaging container 100 is folded by the user without being easily released by the load, the internal pressure of the accommodation space 101 is greatly increased, so that the discharge portion 142 is unfurled.

The pressure regulating portion 143 may be bonded by the same compression bonding heat as the thermocompression bonding portion 130 or may be bonded by the same compression bonding heat as the discharging portion 142.

When the pressure regulating portion 143 is joined to the same compression bonding line as the thermocompression bonding portion 130 by the pressing force, the pressure applied to the discharging portion 142 is dispersed so that only when the pressure exceeds the threshold value, It will burst.

On the other hand, when the pressure regulating portion 143 is joined by the same compression heat as the discharging portion 142, the pressure is distributed to the discharging portion 142 until the threshold value is reached, The lower sheet 110 and the upper film 120 are first peeled off by the pressure applied to the pressure regulating part 143 to absorb the pressure and when the internal pressure continues to increase, So that the discharge portion 142 is blown out.

This is because even if a large pressure is instantaneously applied during circulation, the pressure regulating portion 143 is firstly peeled off, thereby absorbing the pressure and preventing the discharge portion 142 from easily popping up.

2 shows another embodiment of the discharging unit 140. The groove 141 is formed in a V shape so that the pressure applied from the receiving space 101 can be easily concentrated so that the discharging unit 142 can burst.

A pressure adjusting portion 143 of the shape of '?' Or '?' Is formed in the accommodating space 101 adjacent to the inside of the groove 141 or the groove 141 to correspond to the groove 141 of 'V' have.

This structure prevents the discharge portion 142 from popping up by fully distributing the pressure by the pressure regulating portion 143 when pressure is applied from the accommodation space 101 to the groove portion 141 and prevents the internal pressure from reaching the threshold value The discharge part 142 can be easily broken by concentrating the pressure on the vertex of the groove 141.

The shape of the groove portion 141 and the shape of the pressure regulating portion 143 may have various shapes in order to efficiently blow out the discharge portion 142 as well as the above-mentioned shape.
