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

1 is a front view of a food packaging self-supporting pouch according to an embodiment of the present invention before the food is put into the pouch, Figure 2 is a side view of the food packaging self-supporting pouch of FIG.

The present invention, the front film 10, the front film 10 and both ends of the rear film 20 and the edge bonded to the side bonding portion 50 and the edge of the front film 10 and the rear film 20 The main body 40 includes a bottom film 30 bonded to a lower end of the main body 40, and a pouch in which food is accommodated in the main body 40, wherein the pouch has a width direction and a height direction, and the main body ( 40 is formed of the upper body 41 and the lower body 42 formed in order in the height direction, the front film 10 and the rear film 20 at the upper end of the height direction of the upper body 41. ) Is formed with an opening 100 to be joined to each other, and the side joint 50 is formed by the upper side joint 51, the middle side joint 52, and the lower side joint 53 which are sequentially formed in the height direction. Made up and corresponding to the top of the intermediate side junction 52 To provide a cross-facing surface and a pouch that each guard section (80) sealing in a straight line in the width direction and the horizontal direction are formed on one surface of the backing film 20 of the front film 10.

Food is introduced into the pouch through the opening 100, and after the food is introduced into the pouch, the opening 100 is also bonded. The amount of food to be packaged is preferably 90% or less of the volume of the lower main body 42, more preferably 50 to 80% of the input.

The guard unit 80 serves to help the safe opening by cutting the pouch so that the lower body 42 containing the food is not damaged in the process of removing the upper body 41. The guard portion 80 is sealed on one surface of the front film 10 and the rear film 20 in parallel with a desired cutting direction (horizontal direction) so that the lower main body 42 is not damaged. In addition, by inducing to be constantly cut along the horizontal direction, it is possible to have a constant cut along the horizontal direction without using a separate tool such as a knife or scissors, so that it is convenient to eat by using a pouch.

As a method for correctly opening or tearing an existing pouch, a pouch including a zipper is used at an opening of the pouch. On the other hand, the guard portion 80 included in the pouch of the present invention can achieve a desired effect by simply sealing the film on the inner surface of the front film 10 and the back film 20, compared to the conventional method to produce a pouch This has the advantage of simplifying the process and reducing the cost.

The sealing may be made at the top and bottom of the guard portion 80, respectively, and the portion except for the top and bottom of the guard portion 80 may be omitted.

When the sealing is made over the entire area of the guard part 80, the guard part 80 may be cut together instead of preventing the pouch from being cut in the desired cutting direction. Here, the portion that is not sealed can act as a buffer to prevent the guard portion 80 from being broken and cut together.

It is preferable that the portion of the guard portion 80 in which the sealing is omitted has a thickness of 2 to 10 mm. If the sealing portion is less than the range, the cushioning effect of the portion in which the sealing is omitted may not be sufficiently exhibited. If this is exceeded, the guard may not be held before the buffering force is transmitted and may be cut off together.

Portions of the upper and lower ends of the guard portion 80, respectively, in the horizontal direction are preferably also having a thickness of 2 to 10 mm, the strength of the sealing may be insufficient when the range is less than the above range, If the excess portion is too thick, there is a risk that the guard portion 80 is cut off before the cushioning effect of the portion in which the sealing is omitted is exerted, and the sealing cost is excessively generated, which is not economical.

A first cutting aid 70 concave in a direction toward the inside of the main body 40 may be formed at the lower end of the height direction of the upper side junction part 51.

The first cutting aid 70 is formed concave in the direction of the main body 40 and serves as a starting point of cutting when the upper main body 41 is cut. The first cutting aid 70 is formed at a position corresponding to the lower end of the height direction of the upper side joining part 51, that is, the upper end of the height direction of the guard part 80. It is preferable because it is suitable at the time of cutting and using a pouch. Various types of easily tearable tear aids that are well known in the art may be formed. However, in the case of a food containing liquid, the expiration date can be drastically reduced as the thickness of the pouch film for packaging the food becomes thin, so that the thickness of the film is relatively thin compared to other parts so as to be easily torn. The shape of the cutting aid is not preferred.

The length ratio of the upper main body 41 and the lower main body 42 in the height direction may be 1: 1.5 to 1: 2.5.

The pouch of the present invention contains food only by the volume of the lower body 42, which corresponds to a form in which more empty space of the upper body 41 is left than the conventional food packaging pouch. This type, when used in a microwave oven, may have an extra pressure by the empty space of the upper body 41, the pressure inside the pouch is increased, even if the shape of the lower body 42 containing the food deforms the free space Can have It also shows improved durability when carrying or displaying pouches after packing food.

The length ratio of the middle side junction 52 and the lower side junction 53 in the height direction may be 1: 1 to 1: 1.6.

The range of the length ratio is shorter distance between the bottom of the pouch and the guard portion 80 than the conventional pouch for food packaging, which allows the guard portion 80 to receive the force to open the bottom portion of the pouch at a closer distance The pouch allows you to stay open without closing the meal. However, it is not necessarily limited to the scope of the substrate, it can be used by appropriately adjusted according to the type of food accommodated and the material of the film. However, if it is out of the above range, the volume of the lower body 42 is small can not accommodate a large amount of food, or may be unable to maintain the pouch inlet open state.

The length of the lower direction of the lower body 42 in the width direction is gradually narrower from the upper end of the lower main body 42, the lower film 30 is the front film 10 and the three continuous straight lines Bonded with the back film 20, respectively, the three consecutive straight lines are two inclined straight lines extending at an angle of 100 ° to 170 ° from both ends of the center straight line 31 and the center straight line 31, respectively The bottom film 30 is folded on the basis of an imaginary line connecting two vertices where the inclined straight lines 32 meet each other, and the lower side joint part 53 is the bottom film 30. And a bottom-front junction where the front film 10 is bonded and a bottom-back junction where the bottom film 30 and the back film 20 are bonded are formed by being folded and stacked along the imaginary line, The side junction 53 includes the bottom-front junction and the bottom - it may have a stacked junction 54 which is the rear abutment is bonded.

The length of the lower body 42 in the width direction is gradually narrowed along the direction from the top to the bottom, which widens the inlet portion when eating with the pouch, and easily float the liquid or contents in the pouch using a spoon or the like. To improve the stability of the floor at the same time.

The bottom film 30 has a hexagonal shape consisting of two center straight lines 31 and four inclined straight lines 32. When the pouch is self-supporting, the bottom surface and two center straight lines 31 come into contact with each other. Make sure you have stability. The angle between the center straight line 31 and the oblique straight line 32 is an obtuse angle of 100 ° to 170 ° when viewed from the front, it is preferable that the lower side of the film 30 is trapezoidal shape is longer than the lower side. This is because the pouch has a good bottom stability and is convenient for meals using the pouch as a bowl.

The laminated junction 54 may prevent the folded front-bottom junction and the rear-bottom junction from excessively widening, and may serve to prevent the pouch from falling down due to stability of the bottom surface.

The seal formed at the lower end of the guard portion 80 is omitted or thinner in a predetermined portion, and the predetermined portion is formed at a position corresponding to a vertex perpendicular to the vertex where the center straight line 31 and the inclined straight line 32 meet. Can be.

The upper sealing portion of the guard portion 80 is completely sealed in all parts, to prevent damage to the lower body 42 when cutting, the lower sealing portion is omitted in the predetermined portion or the thickness of the sealing is thinner When using a pouch as a substitute for a meal, the guard portion 80 is bent and fixed at a predetermined portion. The bent guard portion 80 maintains the entrance portion of the lower body 42 well open to help the convenience of the meal. The predetermined portion is preferably formed at a position corresponding to a vertex where the center straight line 31 and the inclined straight line 32 of the bottom film 30 meet, so that the overall shape of the lower main body 42 can be more firmly maintained. .

The length ratio of the upper end of the lower body 42 and the lower direction of the lower body 42 in the width direction may be 1.6: 1 to 1.2: 1.

The lower body 42 serves as a bowl when eating, the upper end of the lower body 42 corresponds to the inlet portion of the bowl, the lower portion corresponds to the bottom portion of the bowl. If the widthwise length ratio of the upper and lower ends of the lower body 42 is out of the above range, the bottom stability is decreased or the inlet is narrowed, so that it is not easy to eat liquid or food in the pouch using a cutlery (see FIG. 3). ).

3 shows a state diagram of the lower body 42 used after cutting the upper body 41 from the pouch of FIG. The bottom of the pouch is secured, includes a wide opening, and can be fixed without closing, allowing you to eat right away without having to remove food using a separate bowl.

The upper side junction 51 is formed at a position corresponding to the upper main body 41, and one side of the upper side junction 51 has a vapor discharge portion 60 having a space extending in a direction away from the inside of the main body Is formed, and the upper side joining portion 51 in which the steam outlet 60 is formed has a length in the width direction of the upper side joining portion 51 in which the steam outlet 60 is not formed. The second cutting aid 71 may be formed longer than the length and in which the upper side joining part 51 in which the vapor discharge part is formed is cut a predetermined length in the height direction.

The steam outlet 60 may be used after being cut in the vertical direction, and may be cut by using the second cutting aid 71. After being cut off, the extended space allows the inside and outside of the pouch to communicate with each other, thereby discharging air in the expanded pouch when heated in a microwave oven, and adjusting the food to have an appropriate moisture content. Maintains taste and texture

The first cutting aid 70 serves to guide the steam outlet 60 to be easily cut, and various types of easy tearing aids well known in the art may be formed. However, in the case of a food containing liquid, since the expiration date can be drastically reduced as the thickness of the pouch film for packaging the food becomes thin, the film is formed to be relatively thinner than other parts to be torn. The shape of the cutting aid is undesirable.

The extended space becomes narrower as it moves away from the body 40, and the width may be up to 5 mm.

The wider the width, the easier it is to discharge steam, but if it exceeds the above range, the moisture of the food is excessively evaporated when the food is heated, which may impair the texture of the food. have.

A handle 90 protruding in a direction away from the inside of the main body may be formed in the intermediate side junction 52, and the handle 90 may be empty except for an edge of the handle 90. Can be.

The portion of the film which comes into direct contact with the food after heating the food in the pouch may be burned by the hand, and is formed at the side joint portion which does not come into contact with the hot food. It protrudes in a direction away from the main body to have a larger area than the side joint portion to easily hold the pouch, the part except the edge is empty can be prevented from slipping, and the risk of burn can be further reduced.

The food may be a food containing liquid, such as soup, soup, stew, snacks.

This only means that it is optimized for the packaging of food containing liquids, but is not limited to the above description.
