Description

Straw built-in pouch with residual protection

The present invention relates to flat and upright straw built-in pouches.

Drinking water is distributed in solid solid containers such as glass bottles, cans, cartons, and plastic blow containers, but recently, small pouches made of synthetic resin film sheets are used.

When you drink, you have to tilt your head back like any container, whether it's a solid container or a pouch, but in particular, the pouch is sulky and uneasy to drink, so you can pour it into your mouth and spill it down or contaminate your clothes. You can also use a separate cup or straw.

Instead of using separate straws, a wide variety of techniques have been filed and published regarding straw built-in pouches with straws embedded inside the pouch.

According to Republic of Korea Patent No. 10-0782039 ("Liquid packaging pouch and straw with a straw", 2007, 11. 28. registration) wrap the fusion piece on the straw and then fusion the end of the fusion piece together on the edge of the pouch pouch The technique of fixing in the inside of the is disclosed.

In addition, according to Korean Patent Laid-Open Publication No. 10-2007-0041693 ("Pouches with a built-in straw", published April 19, 2007), the pouch forms a space in which a straw can be inserted and is positioned at the fusion of the edge of the pouch. Techniques are available to open the top of the straw by making a cut.

In addition, according to the Republic of Korea Patent Publication No. 10-0456030 ("Standing container with a built-in straw", registered on October 28, 2004), while being separated from the upper portion by a partition groove formed by cutting a certain depth on the upper side of the pouch A technique is disclosed in which a straw having a cutting groove formed therein is formed and a straw having an upper end in the pouch positioned higher than the cutting groove is fixed inside.

* In addition, according to the Republic of Korea Patent Publication No. 10-2011-0037186 ("Stands built-in standing container", published April 13, 2011), once inside the cutout and the cutout partitioned by a cutout groove formed on one side of the pouch The other end is fixed to the inside of the pouch body is disclosed a technology that constitutes a multi-stage straw, the tubular members of different diameters are mutually fitted to selectively extend length.

However, in the above-described conventional techniques, there are various problems to be improved. First, in the above-described conventional techniques, there is a problem that a considerable amount of residual liquid may be left at the bottom of the pouch after drinking.

Especially in the pouch, it is difficult to visually check the inside of the pouch due to the printing of the outer surface or aluminum coating for UV protection, which can leave a considerable amount of residue, which can lead to waste and residual customer dissatisfaction. The solution to the residual solution is more necessary when the problem is caused by unintentional leakage of the residual liquid.

And, because the pouch is made of soft plastic film sheets with softness, it is sulky, so when drinking the contents of the pouch using a straw, hold it with both hands to drink or hold the top of the pouch to stabilize the standing position of the pouch. In order to improve the convenience of the user, a technique is required to stabilize the standing posture of the pouch even when the pouch is held freely and comfortably with one hand.

Although the problems and problems of the prior art have been described above, the recognition of the problems and problems is not obvious to those skilled in the art.

DETAILED DESCRIPTION Embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. In the drawings, parts irrelevant to the description are omitted in order to clearly describe the present invention, and like reference numerals refer to like parts throughout the specification.

Straw-containing pouch (100,200) according to the first embodiment of the present invention includes a first sheet material (101,201), second sheet material (102,202) and straws (111,211), the first sheet material (101,201) and the second The edges of the

sheet materials

102 and 202 are fused to the first side welded

parts

110A and 210A, the second side welded

parts

110B and 210B, the upper welded

parts

110C and 210C, and the lower welded parts 110D and 201D. Equipped.

A liquid (drinking water) is accommodated in the space between the

first sheet member

101, 201 and the

second sheet member

102, 202 in which the rim is fused, and a straw 111 is incorporated therein. The pouch is a flat plate without a base (as opposed to the upright pouches of FIGS. 3 and 4), and the

first sheet member

101, 201 and the

second sheet member

102, 202 are directly fused at the lower end of the pouch.

The

first sheet member

101 and 201 and the

second sheet member

102 and 202 may include a synthetic resin layer such as CPR polypropylene, low density polyethylene, linear low density polyethylene, etc. as inner walls, and a metal foil layer such as aluminum for UV protection and printing. It may further comprise a layer.

In the bottom portion of the pouch (100,200), there are naturally baselines (120,220) where the first sheet material (101,201) and the second sheet material (102,202) meet, and a small amount of remaining liquid is along the valley including the baseline (120,220). Will move.

According to one feature of the invention, the base line (120,220) has a straight inclination upward from the lowest point (121,221) so that the lowest point (121,221) and such a linear inclination form an inverted triangular shape, the lower end (111A,) of the straw (111,211) 211A is positioned at the

lowest points

121 and 221 of the

base lines

120 and 220, but the lower end of the straw 111 is formed by the first

linear welding portions

113A and 213A or the like to maintain the state. Are attached to (102,202).

The lower ends 111A and 211A of straws are fixed at the same point as the

lowest points

121 and 221 so that the liquid in the pouch is automatically collected at the

lowest points

121 and 221 along the slope 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 suction ports and leave little residual liquid.

According to one feature of the invention, the baseline (120,220) is in the form of a straight line rather than a semi-circle or ellipse that is drooping down, has a slope of the straight line compared to the semi-circle or ellipse that is drooping down to remain at the same height of the bottom end of the straw The amount of liquid is less. In addition, according to one feature 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 inlet can be stably maintained.

In the conventional pouch, while the baseline is horizontal, there is no even the lowest point, according to one aspect of the present invention, it is possible to form the lowest point in the deep of the inverted triangle and to suck a small amount of residual liquid from the deep.

2, the curved portion 211C is formed at the lower end of the straw 211, and the lower end 211A of the straw is positioned between the center portion and the edge of the pouch. The lowest point 221 moves from the center to the edge, so that the overall path length of the straw 211 is shorter and the flow of the liquid is faster than the lower end 211A is formed at the center.

After opening the upper ends of the

pouches

100 and 200 using the

notches

140 and 240, the

stretchable parts

111B and 211B of the

straws

111 and 211 may be bent or extended to be conveniently used. The

stretchable portions

111B and 211B formed at the upper end of the straw can additionally obtain about 150% of the stretched portion by pulling with hands or teeth.

The

linear fusion portions

113A, 113B, 213A, 213B, and 213C serve to fix the

straws

111 and 211 to the

first sheet material

101 and 201 and / or the

second sheet material

102 and 202. The straw is fixed in the production process. In the production process, a straw is placed on one of the first sheet member (101,201) or the second sheet member (102,202) (

protrusions

130 and 230 to be described later may be formed in advance), and then the shape of the linear welded portion Fix the straw by fusing it with heat of seal bar. Thereafter, the other side of the fusion constituting the rim of the fusion constituting the edge of the other fusion and the fusion portion of the overlapping fusion portion 114,214, etc. to be described later, such as fusion constituting the edge is welded at once or divided by heat. Then, after injecting liquid (drinking water) into the pouch, the

upper fusion unit

110C and 210C may be fused to produce a pouch containing liquid and a straw.

In the present application, the 'linear' of the 'linear fusion portion' may be due to a wide range of fusion means including a straight line or a continuous form of darts.

Straw (111.211) is fused with the first sheet material and the second sheet material in a state in which it is in close proximity to the side fusion fusion (110A, 210A) of any one side of the fusion edge, the side fusion fusion (110A, 210A) and The first overlapped

fusion portions

114A and 214A on which the first sheet material and the straw are fused, and the second overlapped

fusion portions

110B and 210B on which the second sheet material and the straw are fused form a Y-shaped beam.

The first

overlap welding portion

114A, 214A and the second

overlap welding portion

114B, 214B are welded by fusion of the sheet material and the straw using a seal bar such as the seal bar shown in Fig. 5A. 1B and 2B, the first side welded

portions

110A and 210A, the first overlapped welds 114A and 214A, and the second overlapped welds, as shown in the cross-sectional views of FIGS. 1B and 2B. The

sections

114B and 214B have a Y-shaped cross section and form a beam extending in the longitudinal direction, and act like a beam of steel used in construction (in the cross-sectional views shown in FIGS. 1B and 2B). There are no voids in the Y-beam, but there may be some voids).

After fusion by heat, the synthetic resin constituting the sheet material and straw may shrink and increase the rigidity. When the soft polyethylene film fabric is also heat-sealed, the fusion site shrinks at the same time as cooling and the fusion zone becomes thicker and thinner. Furthermore, by forming a Y-shaped beam structure, the rigidity like a skeleton is obtained, thereby making it more rigid.

According to one aspect of the present invention by the Y-shaped vertical beam made of fusion, giving a rigid rigidity to the pouch, even if the user grasps the pouch with one hand to make you feel secure and comfortable, as if holding the rod in the hand, pouch when drinking It can be more easily and stably gripping, compared to the conventional pouches that may be sulky due to the liquid contents, the pouch according to one aspect of the present invention can be held in one hand, especially drink the beverage in a stable posture even when holding the bottom of the pouch It works.

In the straw built-in pouch according to an embodiment of the present invention, the straw has a multilayer 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), and the melting point of the resin layer 11-1 at the outermost side is further inside. It is characterized in that it is lower than the melting point of the other resin layer 11-2.

In the mass production process of making thousands of finished products per hour, the straw must be fused in a pouch quickly and accurately at a predetermined position. Therefore, the resin layer inside the straw (inner diameter) has a raw material such as polypropylene or high-density polyethylene with high melting point as before. Even if it is used, low-density polyethylene or linear low-density polyethylene, which has a lower melting point and better compatibility with the pouch inner wall, or a lower melting point is used for the resin layer on the outer surface. Therefore, it is desirable to improve the productivity by coating the outer diameter surface by a two-layer or more multi-layer production technique. Since retort pouches are applied at a high temperature of 100 ° C. to 140 ° C., a CPR polypropylene having good heat resistance and compatibility with an inner wall resin can be used as a resin layer on the outer surface.

Further, 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 and 201 or the

second sheet material

102 and 202. (See FIG. 1 (B) and FIG. 2 (B)).

When drinking, the inner wall of the pouch may be in close contact with the liquid, and the flow may be stopped. To prevent this, one of the

pinholes

112 and 212 having a diameter of about 0.1 mm to 3.5 mm is disposed at the end or the bottom of the straw according to the size of the pouch and the straw. By forming the above, it is a means for blowing air into the inside of the pouch, and the embossed

protrusions

130 and 230 are formed on at least one inner wall to prevent both walls of the pouch from coming into close contact with the liquid. It can flow down and reduce the collection time.

The

protrusions

130 and 230 may be formed to prevent adhesion between both walls, but may be utilized by protruding a brand name, a trademark, or a mark of a product, and the size or position thereof may be arbitrarily set.

Hereinafter, the description of the same or similar parts as in comparison with the first embodiment of the present invention will be omitted and will be described based on differences.

The

pouches

300 and 400 are upright, with

bases

333 and 433 interposed between the lower ends of the

first sheet members

301 and 401 and the lower ends of the

second sheet members

302 and 402.

At the bottom portion of the

pouches

300 and 400, the

first baselines

320A and 420A, where the

first sheet members

301 and 401 and the

bases

333 and 433 meet, have a straight upward slope from the first

lowest points

321A and 421A to allow for the first The lowest points 321A and 421A and the straight slope therefrom form an inverted triangular shape, and the

second base lines

320B and 420B where the

second sheet member

302 and 402 and the

bases

333 and 433 meet the second

lowest points

321B and 421B. The second

lowest point

321B, 421B and the linear inclination therefrom form an inverted triangular shape with a straight upward slope from. 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 ends of the straws are fixed to the base, the first sheet material or the second sheet material to maintain the state.

According to one feature of the invention, the baseline is in the form of a straight line rather than a semi-circle or ellipse that is drooping down, and has a slope of the straight line as compared to the semi-circle or ellipse that is drooping down, so that the amount of residual liquid at the same height of the bottom end of the straw This becomes less. In addition, according to one feature of the invention, the lower end of the straw (311A, 411A) is fixed to the lowest point can maintain the inlet stable. According to one aspect of the present invention, it is possible to form the lowest point in the deep of the inverted triangle and to suck up to a small amount of residual liquid in the deep.

In the conventional upright pouch, the left and right symmetrical configurations have been tolerated like the unwritten ratio in order to maintain the balance of weight, but the unbalanced ratio as in the pouch 300 according to the embodiment of FIG. When breaking and moving the lowest point to the middle left or right middle point, the weight is balanced and the new fact that there is no problem in the upright pouch is applied.

The upright pouch 400 shown in FIG. 4 is a bottle-shaped pouch for coping with a solid glass bottle or a plastic bottle with a larger carrying capacity, and a straw 411 is positioned vertically at the center point of the pouch to provide a linear sealing. It is firmly fixed to the inner wall of the pouch and the bottom end 411A of the straw is set to meet at the lowest point 421.

The position of any one of the first

lowest point

321A, 421A or the second

lowest point

321B, 421B is formed at least 1 mm lower than the other position. In order to make only one lowest point at the bottom of the pouch (300,400), the position of the inverted triangle lowest point on the side where the straw is fixed in the pouch is formed at least 1 mm, about 1 mm to 5 mm lower than the opposite side, Make sure the bottom is one point and the bottom end of the straw sticks here.

And the scale display window for a measurement is formed in a 1st sheet material or a 2nd sheet material. In particular, in the case of packing liquor or the like in an upright pouch, it is necessary to divide the carrying capacity by a predetermined amount and drink it. At this time, a transparent window or a semi-transparent window marked with scales is formed for checking the remaining amount of the carrying solution.

And the fused rim is formed finger hole perforation 430 (see Fig. 4). In general, the upright type has a larger size and a little larger capacity than a small pouch, so it can feel slippery and heavy in lifting by hand, and provides convenience for handling by forming a finger hook perforation 430 on the upper wings of the pouch. can do.

In addition, the first sheet member or the second sheet member may be semi-permeable in which the base is color-treated with a light monochromatic color so that the liquid is visible. The clear, transparent pouch fabric that looks bright is colored in beautiful and light monochromatic colors such as lightblue, green, yellow, orange, and red to protect the contents from UV rays and give people a visual and emotional refreshing feeling. Even if the light monochromatic treatment is partial rather than the entire one side, the desired purpose can be achieved.

The upper end of the pouch may be a bottleneck shape, an animal shape, a circle, a triangle, a rectangle, a hexagon, or a character shape. Although the upper end of the pouch of FIG. 4A has a bottleneck shape, the pouch upper end part may be transformed into a shape of various objects such as an animal shape, a circle, a triangle, a rectangle, a hexagon, and a character.

In addition, as illustrated in FIG. 5C, the first sheet member or the second sheet member may be formed with a transparent window or a translucent window 50 at least exposing the bottom end 11A of the straw 11. As illustrated in FIG. 5 (D), the outer surface of the first sheet member or the second sheet member has a straw-shaped figure 60 or a straw at a position corresponding to the straw, or a position corresponding to the lower end of the straw. A picture that displays can be printed.

As described above, in most pouches, it is difficult to visually check the inside of the pouch due to printing of the outer surface or aluminum coding for UV protection, so that at least the bottom end 11A of the straw 11 is transparent. The window or translucent window (50) has the advantage that the user can drink while checking the residual liquid, and not only notifies the user of the straw due to the printed straw-shaped picture (60) or the picture showing the straw This has the advantage of helping to position the pouch to minimize residual fluid.
