Description

(Straw Builtin Pouch For Preventing Drink Feints)

The present invention relates to a straw-mounted straw-type pouch.

Drinking water can be distributed in solid containers such as glass bottles, cans, cartons, plastic blow containers, etc. Recently, small pouches made of synthetic resin film sheets have been used.

It is the same as any container, either a solid container or a pouch, which has to be tilted backward when drinking, but especially because the pouch is flabby and the posture of drinking is unstable, it will be poured into the mouth and poured down, There are many bars, separate cups and straws are often used.

Rather than using a separate straw, a wide variety of techniques have been filed and disclosed relating to a straw-mounted pouch in which the straw is built into the interior of the pouch.

According to Korean Registered Patent No. 10-0782039 ("Liquid pouches and straws with built-in straws", registered on November 28, 2007), the fused pieces were wound on the straws and then one end of the fused pieces was fused together on the rim of the pouches, And a method of fixing the light emitting diode to the inside of the light emitting diode.

According to Korean Patent Laid-Open Publication No. 10-2007-0041693 ("pouch with straw", published on Mar. 19, 2007), it is possible to form a space in which a straw can be inserted into a fused portion of a pouch rim, A technique has been disclosed that can open and expose the top of the straw.

According to Korean Registered Patent Publication No. 10-0456030 ("Standing container with a straw", registered on October 28, 2004), the upper part of the pouch is partitioned by a dividing groove formed at a predetermined depth, There is disclosed a technique in which a unsealed portion formed with a cutout groove is formed and a straw having an upper end positioned higher than the cutout is fixed to the inner side.

According to Korean Patent Laid-Open Publication No. 10-2011-0037186 ("standing straw container with built-in straw", published on Mar. 13, 2011), one end is cut out by the cutout portion formed by the cutout groove formed at one side of the pouch, And the other end is fixed to the inside of the pouch body, and a tubular member having a different diameter is fitted to each other to selectively extend the length of the multi-stage straw.

However, in the above-mentioned prior arts, there are various problems to be improved. In the conventional techniques described above, there is a problem that a substantial amount of residual liquid can be left on the bottom of the pouch after drinking.

Particularly, in the pouch, since it is difficult to visually check the inside of the pouch due to the printing of the outer surface or the aluminum coating for blocking ultraviolet rays, it is possible to leave a considerable residual liquid, resulting in waste caused by the residual liquid, There is a need for a solution to the residual liquid in consideration of the unintentional flow of the residual liquid and the like.

Since the pouch is made of a synthetic resin film sheet made of a soft material, when the contents of the pouch are drunk by using a straw, the pouch is held by two hands to be used for drinking or holding the top of the pouch to stabilize the standing position of the pouch. In order to improve the user's convenience, a technique is required to stabilize the standing posture of the pouch even if the pouch is grasped freely and comfortably with one hand.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.

Korean Registered Patent No. 10-0782039, "Liquid packaging pouches and straws with straws", 2007, 11. 28.

An object of the present invention is to provide a straw-built pouch capable of reducing the residual liquid remaining in the pouch when drinking.

Another object of the present invention is to provide a straw-fitted pouch capable of gripping the pouch more easily and stably when drinking.

A straw-fitted type pouch according to one aspect of the present invention is a straw-fitted type pouch for accommodating a liquid in a space between a first sheet member and a second sheet member,

Wherein the base line at which the first sheet member and the second sheet member meet at the bottom portion of the pouch has a straight line inclination upward from the lowest point (121, 221), so that the lowest point (121, 221) And the lower ends 111A and 211A of the straw are located at the lowest points 121 and 221 and are fixed to the first sheet material or the second sheet so that the lower end of the straw is maintained in the state .

Wherein the pouch is an upright type in which a bottom is interposed between a lower end portion of the first sheet material and a lower end portion of the second sheet material, wherein a first base line, at which the first sheet material and the underside meet, And a second baseline along which the second sheet material meets the underside has an upward linear slope from the second lowest point, so that the first baseline and the second baseline meet, Wherein the lower end of the straw is located at the first lowest point or the second lowest point and the lower end of the straw is positioned at the lower end of the straw, And is fixed to the sheet material or the second sheet material.

In the straw-containing pouch, the straw is fused with the first sheet material or the second sheet material, and the straw is composed of two or more resin layers, wherein the melting point of the resin layer at the outermost periphery is located inside Is lower than the melting point of the other resin layers.

In the straw-mounted pouch, the straw is formed with at least one pinhole having a diameter of 0.1 mm to 3.5 mm.

In the straw-mounted pouch, the first sheet member or the second sheet member is provided with a plurality of protrusions protruding inward.

In the straw-fitted pouch, an outer surface of the first sheet material or the second sheet material is provided with a straw-shaped figure or straw on a position corresponding to the straw or a position corresponding to the lower end of the straw, And is printed.

In the straw-mounted pouch, a curved portion is formed at a lower end of the straw, and a lower end of the straw is positioned between a central portion and an edge of the pouch.

In the straw-mounted pouch, any one of the first lowest point and the second lowest point is formed to be 1 mm or more lower than the other position.

In the straw-mounted pouch, the first sheet member or the second sheet member is provided with a scale display window for metering.

In the straw-mounted pouch, the fused perforations may be formed by fingers.

In the straw-mounted pouch, the first sheet material or the second sheet material is semipermeable, the base of which is treated with a pale monochrome color so that the liquid can be seen.

Wherein the straw is fused with the first sheet material and the second sheet material in a state in which the straw is in proximity to a side fused portion of any one side of the fused rim, A first overlapping fused portion in which the sheet material and the straw are fused, and a second fused portion in which the second sheet material and the straw are fused together form a Y-shaped beam.

In the straw-mounted pouch, the upper end of the pouch may be in the shape of a boottlenek, an animal, a circle, a triangle, a square, a hexagon, or a character.

According to one aspect of the invention, the baseline is a straight line shape that is not a curved line, such as a semicircle or an ellipse that is floated downward, but has a straight line slope relative to a semicircle or ellipse that is underneath, This has the advantage of being less. In addition, according to one aspect of the present invention, since the lower end of the straw is fixed to the lowest point, there is an advantage that the inlet of the straw can be stably maintained in a place where the last residue liquid collects. In the conventional pouch, basal line is horizontal, and even the lowest point is not present. On the other hand, according to one aspect of the present invention, there is an advantage that a lowest point is formed deeply at the reverse osmosis angle and a small amount of residual liquid can be sucked from deep.

According to an aspect of the present invention, a curved portion is formed at the lower end of the straw, and a lower end of the straw is positioned between a center portion and an edge of the pouch. The lowest point moves from the center to the edge, The length of the entire length of the straw is shortened and the flow of the liquid is accelerated.

In addition, according to one aspect of the present invention, the Y-shaped vertical beam as a fused portion imparts firm rigidity to the pouch, and even when the user holds the pouch with one hand, it feels as if the rod is held in the hand, The pouch according to one aspect of the present invention can be gripped in one hand, especially when the lower end of the pouch is gripped, compared to a conventional pouch in which the pouch can be gripped more easily and stably, There are advantages to be able to.

According to an aspect of the present invention, the straw of the straw-built pouch is formed of two or more resin layers, and the melting point of the resin layer in the outermost layer is lower than the melting point of the other resin layers inwardly, There is an advantage that it can be fast and accurately fused to a predetermined position.

The straw-fitted pouches 100 and 200 according to the first embodiment of the present invention include the first sheet materials 101 and 201, the second sheet materials 102 and 202 and the straws 111 and 211. The first sheet materials 101 and 201, The rim to which the sheet members 102 and 202 are welded is formed by the first side fused portions 110A and 210A, the second side fused portions 110B and 210B, the upper fused portions 110C and 210C and the lower fused portions 110D and 201D Respectively.

(Drinking water) is stored in the space between the first sheet materials 101 and 201 and the second sheet materials 102 and 202 to which the edges are fused, and the straw 111 is built in. 3 and 4), the first sheet material 101, 201 and the second sheet material 102, 202 are directly fused even at the lower end of the pouch.

The first sheet materials 101 and 201 and the second sheet material 102 and 202 may include synthetic resin layers such as CPR polypropylene, low density polyethylene and linear low density polyethylene as inner walls, and a metal foil layer, such as aluminum, Layers, and the like.

In the bottom portion of the pouches 100 and 200, the base lines 120 and 220 where the first sheet materials 101 and 201 meet the second sheet materials 102 and 202 are natural and the remaining small amount of liquid flows along the valleys including the baselines 120 and 220 It moves.

According to one feature of the present invention, the baseline 120,220 has a straight line slope upward from its lowest point 121,221 and has its lowest point 121,221 and its linear slope inversely angled, and the bottom ends 111A, The lower end of the straw 111 is positioned at the lowest points 121 and 221 of the baseline 120 and 220 by the first linear welded portions 113A and 213A or the like so that the first sheet materials 101 and 201, (102, 202).

The lower ends 111A and 211A of the straw are fixed at the same points as the lowest points 121 and 221 so that the liquid in the pouch automatically collects at the lowest points 121 and 221 along the inclination and the lower ends of the straws 111 and 211 fixed to the lowest points 121 and 221 The ends 111A and 211A suck up all of the collected liquid as the suction port and leave almost no residual liquid.

According to one aspect of the present invention, the baseline 120, 220 is a straight line shape that is not a curved semicircle or an ellipse, but has a straight line slope relative to the semicircle or ellipse that underlies the bottom, The amount of liquid becomes smaller. According to an aspect of the present invention, since the lower ends 111A and 211A of the straws 111 and 211 are fixed to the lowest points 121 and 221, the suction port can be stably maintained.

According to one aspect of the present invention, the basal line is horizontal in the conventional pouch, so that it can not be the lowest point. On the other hand, it forms the lowest point deep within the reverse osmosis angle and can inhale a trace amount of residue.

2, a curved portion 211C is formed at the lower end of the straw 211, and a lower end 211A of the straw is located between the central portion and the edge of the pouch. The lowest point 221 moves from the center to the edge and the entire path length of the straw 211 is shortened and the flow of the liquid is faster than the lower end 211A is formed at the center.

After the upper ends of the pouches 100 and 200 are opened by using the notches 140 and 240, the stretching and contracting parts 111B and 211B of the straws 111 and 211 may be bent or extended to be convenient. The stretchable and contractible portions 111B and 211B formed at the upper end of the straw can be extended by about 150% by pulling it with a hand or a tooth.

The linear fused portions 113A, 113B, 213A, 213B and 213C serve to fix the straws 111 and 211 to the first sheet materials 101 and 201 and / or the second sheet materials 102 and 202, During the production of the straw is fixed. In the production process, one of the first sheet materials 101 and 201 or the second sheet materials 102 and 202 is raised and placed on a sheet material (the protrusions 130 and 230 to be described later may be formed in advance) And the straw is fixed by welding with the heat of the seal bar having the seal bar. After that, the opposite sheet material is covered and then the fused portions except for the upper fused portions 110C and 210C of the fused portions constituting the rim and the fused portions such as superposed fused portions 114 and 214 to be described later are fused together by heat or heat. Then, a liquid (drinking water) is injected into the pouch and then the upper fusion portions 110C and 210C are fusion-bonded to produce a pouch containing liquid and straw.

The 'linear' of the 'linear welded portion' in the present application may be due to a wide range of fusing means, including a straight line or a continuous type of darts.

The straw 111.211 is fused with the first sheet material and the second sheet material in a state of being close to the side fused portions 110A and 210A of any one side of the fused frames and the side fused portions 110A and 210A First superimposed welded portions 114A and 214A to which the first sheet material and straw are welded and second superposed welded portions 110B and 210B to which the second sheet material and straw are welded form a Y-shaped beam.

214A and the second superposed fused portions 114B, 214B by fusing the sheet material and the straw using the same seal bar shown in Fig. 5 (A) As shown in the cross-sectional views of FIGS. 1B and 2B, the first side fused portions 110A and 210A, the first overlapping fused portions 114A and 214A, and the second overlap fused The sections 114B and 214B form a Y-shaped beam extending in the longitudinal direction and act like a section steel used in construction (see the sectional views shown in Figs. 1 (B) and 2 (B) There is no gap in the Y-shaped beam, but there may be some voids).

The synthetic resin constituting the sheet material and the straw after fusion bonding by heat shrinks and the rigidity may increase. When the soft polyethylene film fabric is also heated and fused, the fused portion is contracted at the same time as cooling, and the fused portion becomes thick and becomes stiff. Further, since the Y-shaped beam structure is formed, rigidity like a skeleton is obtained and it becomes more solid.

According to one aspect of the present invention, the Y-shaped vertical beam as a fused portion imparts firm rigidity to the pouch and makes the user feel safe and comfortable as if holding the rod in the hand even when the user holds the pouch with one hand, The pouch according to one aspect of the present invention can be held in one hand and can drink beverage in a stable posture even when the lower end of the pouch is gripped, in particular, as compared with a conventional pouch in which the liquid contents may swell It is effective.

In the straw-mounted pouch according to an embodiment of the present invention, the straw has a multi-layer structure. The straw is fused with the first sheet material or the second sheet material and is composed of two or more resin layers as illustrated in Fig. 5 (B), wherein the melting point of the resin layer 11-1 at the outermost side Is lower than the melting point of the other resin layer (11-2).

In the mass production process of making the finished product several thousands of times per hour, the straw in the pouch must be fused to a predetermined position quickly and accurately. Therefore, the resin layer on the inside (inside diameter) of the straw is made of polypropylene or high density polyethylene Even if used, the resin layer on the outer surface is made of a low-density polyethylene or a linear low-density polyethylene having a lower melting point and a good compatibility with the physical properties of the inner wall of the pouch, or a low-temperature functional resin having a lower melting point and a lower heat- It is also desirable to improve the productivity by coating the outer surface with a 2-layer or multi-layer production technique. Since retort pouches are sterilized at a temperature of 100 ° C to 140 ° C, CPR polypropylene, which has good heat resistance and good compatibility with the inner wall resin, can be used as the resin layer on the outer surface.

At least one pinhole having a diameter of 0.1 mm to 3.5 mm is formed in the straws 111 and 211 and a plurality of protrusions 130 and 230 protruding inward are formed in the first sheet material 101 or 201 or the second sheet material 102 or 202 (See Figs. 1 (B) and 2 (B)).

In order to prevent this, the pinholes 112 and 212 each having a diameter of about 0.1 mm to 3.5 mm may be attached to the middle of the straw or the lower end of the straw in accordance with the size of the pouch and the straw, Shaped protrusions 130 and 230 are formed on at least one inner wall of the pouch to prevent the both walls of the pouch from being brought into close contact with the liquid so that the flow of the liquid is smoothly stopped down So that the collection time can be shortened.

Although the protrusions 130 and 230 are formed for preventing the two walls from coming into close contact with each other, the protrusions 130 and 230 can be used by turning a brand name, a trademark, a mark, or the like of a product.

4 (A) is a front perspective view, Fig. 4 (B) is a cross-sectional view along CC 'and Fig. 4 (C) is a cross- It is an explanatory diagram of the reverse osmosis shape.

Hereinafter, the same or similar parts as those of the first embodiment of the present invention will be omitted and the differences will be mainly described.

The pouches 300 and 400 are of an upright type in which the bottoms 333 and 433 are interposed between the lower ends of the first sheet materials 301 and 401 and the lower ends of the second sheet materials 302 and 402.

In the bottom portion of the pouches 300 and 400, the first baselines 320A and 420A where the first sheet materials 301 and 401 meet the undulations 333 and 433 have an upward straight slope from the first bottoms 321A and 421A, The second base lines 320B and 420B where the bottom points 321A and 421A and the straight line inclination thereof form an inverted triangular shape and the second sheet members 302 and 402 and the underside 333 and 433 meet are the second lowest points 321B and 421B, The second lowest points 321B and 421B and the linear gradient therefrom form an inverted triangular shape. The lower ends 311A and 411A of the straws 311 and 411 are positioned at the first lowest point or the second lowest point, and the lower end of the straw is fixed to the underside, the first sheet material or the second sheet material so as to maintain the state.

According to one aspect of the present invention, the baseline is a straight line shape that is not a curved line such as a semicircle or an ellipse which is floated downward, and has a straight line inclination relative to a semicircle or an ellipse that hangs downward, . Further, according to one aspect of the present invention, since the lower ends 311A and 411A of the straw are fixed to the lowest points, the suction port can be stably maintained. According to one aspect of the present invention, a deepest point of reverse osmosis can be formed, and a deep residue can be sucked in a small amount of residual liquid.

In the conventional upright pouches, it is common practice to symmetrically adjust the left and right sides of the center of the pouch in order to maintain the balance of weight. However, like the pouch 300 according to the embodiment of FIG. 3, We found a new fact that the weight was balanced and the erection of the pouch did not interfere even if the low point was moved to the left or right mid point.

The upright pouch 400 shown in Fig. 4 is a bottleneck pouch for accommodating solid glass bottles or plastic bottles having a relatively large carrying capacity, in which the straw 411 is vertically positioned at the center point of the pouch and linearly sealed And the lower end 411A of the straw is set to meet with the lowest point 421 in one place.

The position of any one of the first lowest point 321A, 421A or the second lowest point 321B, 421B is formed to be 1 mm or more lower than the other position. In order to make only one bottom point on the bottom of the pouches 300 and 400, the position of the reverse osmosis lowest point on the surface to which the straw is stuck in the pouch is formed to be 1 mm or more and about 1 mm to 5 mm lower than the opposite side, Make the lowest point one and stick the bottom end of the straw there.

The first sheet member or the second sheet member is provided with a scale display window for metering. Particularly in the case of packing a mainstream or the like in an upright pouch, it is necessary to drink a certain amount of the supported capacity. At this time, a transparent window or a translucent window having a scale mark is formed for checking the remaining amount of the carried liquid.

And a finger hole 430 is formed in the fused edge (see FIG. 4). In general, the upright type is larger than the small pouch and has a large capacity, so that it can feel slippery and heavy feeling by the hand. By forming the perforation (430) with the finger of the thickness of the finger on the upper wings of the pouch, can do.

The first sheet material or the second sheet material can be made semi-transparent so that the base is colored with a light monochrome so that the liquid can be seen. The transparent pouch fabric that looks clear into a clear beverage can be treated with a beautiful and pale monochromatic color such as lightblue, green, yellow, orange, red, etc. to protect the contents from ultraviolet rays and to provide visual and emotional refreshing feeling to people. The light monochromatic treatment can achieve the desired purpose even if it is partial rather than whole surface.

The upper end of the pouch may be in the shape of a boottlenek, an animal, a circle, a triangle, a rectangle, a hexagon, or a character. The upper end portion of the pouch in Fig. 4 (A) is in the form of a bottleneck, but it can be modified into various objects such as an animal shape, a circle, a triangle, a square, a hexagon, and a character.

5 (C), it is possible to form a transparent window or a translucent window 50 at least exposing the lower end 11A of the straw 11 to the first sheet material or the second sheet material 5 (D), the outer surface of the first sheet material or the second sheet material is provided with a straw-like figure 60 or a straw at a position corresponding to the straw, or at a position corresponding to the lower end of the straw, To be printed.

As described above, in most pouches, it is difficult to visually check the inside of the pouches due to printing of an outer surface or aluminum coding for cutting off ultraviolet rays. It is difficult to visually check the inside of the pouches, There is an advantage that the user can drink while checking the residual liquid by the window or translucent window 50, and not only notifying the user of the presence of the straw due to the printed straw-like figure (60) , And the pouch can be used to minimize the residual liquid.
