The present invention relates to a beverage packaging container, in which the guide grooves formed on the outer surface of the beverage packaging container packaged to seal the contents are cut out by the external pressure of the straw and the straw is inserted into the container to consume the contents. It relates to a beverage packaging container characterized in that.

In general, beverage packaging containers are largely divided into PET bottles, aluminum cans, paper cartons, glass bottles, and pouch packs according to their materials. It is further stimulating the desire to buy.

Here, the pouch refers to a small pouch, and the beverage packaging pouch is used to store the contents for a long time or to carry after sealing the contents inside the pack made of synthetic resin.

PET pouch pack containers can be stored for a long time because they are not distorted or corroded like cans, and can be easily torn or worn like cartons, and there is no risk of rupture or cracking like glass bottles. none.

It is also softer and lighter than canned food, making it easy to carry and simple to open.

As such, the pouch pack of PET material, which is widely used because it can be stored in a sealed state for a long time and is easy to carry and has a light advantage, is to be kept closed by storing the contents in a pack made of synthetic resin, as described above. , When drinking, cut one end with scissors or a knife to open and then drink or drink straw (strow) in the open area, or drink along the cup.

Conventional pouches as described above were invaluable in terms of production and distribution, but are useful for keeping the contents sealed. However, in the user's side, contents are spilled or splashed during the cutting process to contaminate the user's clothes, skin or surroundings. Etc. There is a problem in handling for the user.

In particular, in the case of a pouch used for packaging and storing expensive herbal medicines, the producer or supplier and the user themselves have to pay more attention to the hygienic drinking of the user, and through the incision opened by the external force as described above. If the medicinal herbs are leaked to the outside, the economic loss to the user is indescribable.

In general, when drinking the contents by simply using a straw is provided with a straw attached to the body of the pack, such as a pouch pack of PET material is not easily cut with a straw only because of the characteristics of the pet insert the straw as shown in Figures 1 and 2 The area is specially thin so that the straw is easily penetrated.

1 is a plan view and a partially enlarged cross-sectional view of a conventional PET-based beverage pack container body 10, in which a straw film is inserted into a pack container and then sealed with a thin film.

As shown in the figure, the pouch container body 10 is a PET layer 11 of the outer surface, an aluminum layer 13, a PE layer 15 of the inner surface and the adhesive layer (12, 14) for bonding the respective layers. It is composed by laminating).

In addition, the pouch container body 10 is formed with an incision that can be easily cut with a straw, consisting of a straw insertion opening 18, a vinyl layer 16, a bonding surface 17 located in the center of the top of the pack container. It is.

The straw insertion hole 18 is a circular through hole bored to have the same size as the straw diameter, and the vinyl layer 16 is padded to seal the straw insertion hole 18 and opened integrally with the pack inner surface. It consists of the said joining surface 17 joined by crimping | bonding.

 Thus, in order to ensure that the straw penetrates the pouch container body 10 and is inserted into the pack, the vinyl layer 16 bonded to the straw inserting opening 18 is cut into the pointed steeple of the straw, and the vinyl layer cut out. Insert the straw into (16) to drink the contents.

 In FIG. 2, a PET material of a beverage packaging container formed by laminating and laminating a coating layer 21, an ink layer 22, a paper 23, an adhesive layer 24, an aluminum foil layer 25, and a plastic coating layer 26. Pouch container body 20.

The cutout portion of the pouch container body 20 is an aluminum foil that is left after removing the coating layer 21, the ink layer 22, the paper 23, the adhesive layer 24 with a laser to form a straw insertion hole into which a straw is inserted. The layer 25 and the plastic coating layer 26 are comprised.

The pouch bodies of the beverage packaging containers of FIGS. 1 and 2 are not only hard to cut the plastic layer with a straw, but also tightly fixed to the body of the pouch with one hand in cutting the plastic layer into the spire of the straw. Hold the other hand to give a strong external pressure to the straw to incise the plastic layer of the incision, so the contents of the inside are often popped out by the gap between the straw and the vinyl layer by the pressing of the hand holding the body. There is a downside to it.

In addition, when the straw comes into contact with the straw to cut the plastic layer with the straw, the straw slips easily from the plastic layer, causing the incision to fail, and after several failures, even the spire of the straw is worn out or broken. Can make it even more difficult.

In particular, the prior art of FIG. 2 may seem simple, but the laser used in the prior art consumes a lot of cutting time since it must cut at least an area larger than the diameter of the straw.

The present invention is conceived in view of the problems with the pack of the PET material used as the conventional beverage packaging container, the cutting portion is formed by cutting a plurality of cut lines by external pressure through the straw inserting the straw into the container It is an object of the present invention to provide a beverage packaging container.

Another object of the present invention is to provide a beverage packaging container in which a plurality of cutting lines formed in the cutout portion are generated by removing the PET layer by a laser.

As shown in Figure 3, the body 100 of the beverage packaging container is a conventional stand pouch pack (Stand Pouch Pack).

The stand pouch pack is also called a "retort pouch" or "flexible can", and is formed by bonding a plurality of layers of the synthetic resin material, which is usually felt as one sheet.

The synthetic resin film, which is the material of the stand pouch pack, is made by laminating a three-layered polyester foil on the outside of a bag containing a beverage, an aluminum foil on the middle layer, and a polypropylene film layer on the inside.

The contents are put into the bag, heated, sealed, and then sterilized by pressure sterilization and pressure cooling at a temperature of 105 to 120 ° C. to be immediately cooled and distributed.

The lamination method is a dry lamination method using an adhesive, but also in a melt state during film forming. In this case, a coating PE is used instead of an adhesive.

The reason for laminating is to make the desired use by utilizing the characteristics of each raw material.PET is used as a surface material of packaging materials because it has excellent barrier properties against external air, excellent heat resistance and printability, and aluminum foil with air. It is used as an intermediate material because of its excellent barrier properties. PE has a strong oxidation resistance of pouches, so it is not deformed regardless of internal materials and has excellent heat sealing properties and is used as an internal material of pouches. The body 100 is formed by laminating PET + aluminum + PE in order to further increase the barrier property with the outside air.

Both sides of two sheets of synthetic resin laminated with PET + aluminum + PE are heat-sealed to form a space.

The body 100 is composed of a PET layer 110, an aluminum foil layer 120, a PE layer 130 and adhesive layers (101, 102) to bond the respective layers integrally.

The PET layer 110 is a PET or OPP film is used and the thickness is selected from 12 mu m or 25 mu m.

In addition, the thickness of the aluminum of the aluminum foil layer 120 is selected from 7 mu m, 9 mu m, 12 mu m.

In addition, the CPP or LLDPE film of the PE layer 130 is generally selected in an alternative 5 mu m unit from 30 mu m ~ 120 mu m.

A cutout 140 is formed at the top center portion of the PET layer 110 of the body 100, and the cutout 140 includes a cutout line 141 and a cutout end 142.

The cutout 140 includes a straight line connecting the pair of cutouts 142 and an independent area generated in the PET layer 110 with the cutout line 141 as a boundary.

The cutting line 141 is a circular line having a width of about 1 mm in the form of 0.4 to 0.7 mm diameter, one side of which is opened by the cutting end 142.

The diameter of the perforated line 141 is formed in consideration of the diameter of the straw, and slightly larger than the diameter of the straw to prevent the pack from being fully compressed by the suction pressure when drinking, so that the contents can be completely consumed.

In this case, the cutting line 141 is formed only on the PET layer 110, and the PET layer 110 is cut by a laser, thereby causing the PET layer 110 and the adhesive layer 101 to cut off the cutting line 141. Depending on the shape of the will be removed.

The cutting end 142 is a pair of points corresponding to both ends of the cutting line 141, and corresponds to the start point and the end point of the laser cutting process.

Figure 4 is a view showing a cross-sectional view and a straw of the cut portion of the beverage packaging container of the present invention.

As shown in FIG. 4, when an external pressure is applied to the end of the straw 1 by cutting off a point of the cutout 140, the cutout line 141 in which the PET layer 110 is not laminated is the aluminum foil layer. Exposed to 120 and the PE layer 130 is directly subjected to the tensile force.

In this case, in particular, when an external pressure is applied to the center point of the cutout 140, a uniform tensile force is generated near the cutout line 141, thereby cutting the cutout 140 with less force.

In addition, the diameter of the straw (1) should be smaller than the diameter of the cutout portion 140, and the external pressure is applied to any portion of both ends of the straw (1) without the need to cut the cutout with only the spire of the straw as in the conventional straw Even if incision is possible.

The aluminum foil layer 120 and the PE layer 130 having a tensile force, although stretched to some extent, are easily ruptured and cut along the cut line 141.

A through hole penetrating the body 100 is generated by the cut portion 140 cut out, and the through hole becomes a straw insertion hole into which a straw is inserted.

In addition, the cut out portion 140 is inserted into the body 100 together with the insertion of the straw 1, wherein the shortest straight portion connecting the cutting end 142 is inserted into the inside to be folded and the cutout portion 140 is prevented from falling from the body 100 falls to the contents.

5 is a plan view of a cutout according to a second embodiment of the beverage packaging container of the present invention.

As shown in the figure, the cutout 150 has three cutouts 151, 153, and 155, and cutouts 152, 154, and 156 formed at both ends of the cutouts 151, 153, and 155, respectively. It includes.

The structure and structure of the synthetic resin material laminated to form the body of the second embodiment is not only the same as the structure and structure of the body 100 described in the first embodiment of FIG. 3, but also the cut lines 151, 153, and 155. ) And the cutting edges 152, 154 and 156 are also the same as the shape and structure of the cutting line and the cutting edge described in the first embodiment of Figure 3 will be omitted.

In addition, the cut lines 151, 153, and 155 are also generated by cutting the PET layer 110 by a laser.

The cutout 150 includes a plurality of cutouts and cutouts formed in the inner area and include an innermost area bordering the cutout line 155 and the shortest straight line connecting the outermost cutouts 156. do.

The diameter of the perforated line in the second embodiment is different from the diameter of the perforated line in the first embodiment, the diameter of the perforated line 151 is 2 ~ 3mm, the diameter of the perforated line 153 is 4 ~ 5mm, The diameter of the perforated line 155 has a respective dimension of 6 ~ 7mm.

In other words, according to the diameter of the straw inserted into the cutout 150, the straw is provided to correspond to the diameter of the insertion hole for each type of straw, which can have various sizes so that the straw can be flexibly inserted.

For example, the conventional pouch pack was sold as a set by attaching a straw having a diameter equal to or slightly smaller than the diameter of the straw insertion hole formed at the top, but the straw attached to the body is lost during the distribution process and is lost. The diameter of the straw does not correspond to the diameter of the insertion hole may be impossible to insert the straw.

In addition, the perforations are formed at intervals of 1 to 1.5 mm, respectively.

The cutting ends 152, 154, and 156 of the cutout 150 may be formed in the same direction or in separate directions.

The shortest straight length connecting the pair of cutting ends 152, 154, and 156, that is, the distance of the pair of cutting ends is proportional to the diameter of the cutting lines 151, 153, and 155.

When an external pressure is applied to one end of a straw having a diameter of about 2 mm at the middle of the cutout portion 150 of the beverage packaging container according to the second embodiment, the aluminum foil layer 120 exposed to the outside by the cutout line 151. ) And the PE layer 130 is stretched to some extent due to the tensile force is easily broken and is cut along the cut line 151.

In addition, when an external pressure is applied to one end of a straw having a diameter of about 4 mm at an intermediate point of the cutout 150, the aluminum foil layer 120 and the PE layer 130 exposed to the outside by the cutout line 153. The tensile force is generated and stretched to some extent and is easily ruptured and cut along the cut line 153.

In addition, when an external pressure is applied to one end of the straw having a diameter of about 6 mm at the middle of the cutout portion 150 of the beverage packaging container, the aluminum foil layer 120 and the PE layer exposed to the outside by the cutout line 155. 130 is stretched to some extent due to the tensile force is easily ruptured is cut along the cut line 155.

The through hole generated in the body 100 by the cut out portion 150 becomes a straw insertion hole into which a straw is inserted. The diameter of the insertion hole is changed depending on which cutting line is cut.

In addition, the cut out portion 150 is inserted into the interior of the body 100 with the insertion of a straw, and the shortest straight portion connecting the pair of cutting ends is inserted into the interior to be folded away from the body 100 This will prevent the contents from falling.

At this time, when the cutting line 151 is cut, the shortest straight line connecting the pair of cutting ends 152 is folded, and when the cutting line 153 is cut, the shortest straight line connecting the pair of cutting ends 154 is folded. When the cutting line 155 is cut, the shortest straight line connecting the pair of cutting ends 156 is folded.

6 is a plan view of a straw insertion opening according to a third embodiment of the beverage packaging container of the present invention.

As shown in FIG. 6, the cutout 160 includes cut lines 161 and 163 and cut ends 162 and 164.

The body of the third embodiment is configured by laminating in the same manner as the same material as the synthetic resin materials constituting the body of the first embodiment, and the shape and dimensions of the cut line and the cut end are also the cut line and the cut line of the first embodiment. However, since the same as or similar to the above, detailed description thereof will be omitted.

In addition, the cutting lines 161, 163, and 165 are also generated by cutting the PET layer 110 by a laser.

The cutout 160 has a cutout line and a cutout end formed in the PET layer 110 and the PE layer 130, respectively, and have the shortest length and the cutout line 161 and 163 connecting the pair of cutout ends 162 and 164. Corresponds to the area of the inner circle bounded by.

That is, when an external pressure is applied to the central point of the cutout portion 160 at one end of the straw, only the aluminum foil layer 120 exposed by the cutout lines 161 and 163 receives a tensile force and a very weak aluminum foil layer. 120 ruptures easily.

When the cutting unit 160 is cut by the rupture of the aluminum foil layer 120 to form a straw insertion hole, which is a through-hole penetrating the body, the straw is easily inserted to drink the contents.

As shown in the plan view of the straw insertion opening according to the third embodiment of FIG. 7, the cutout 170 includes cut lines 171 and 173, a cut end 172, and a center point 174.

Since the cutout line 171 has the same shape and size as the cutout line 141 of the first embodiment, detailed description thereof will be omitted.

The cutting line 173 is formed by a plurality of straight lines having the same length that intersects the circular cutting line 171.

The number of the cutting lines 173 will be appropriate so that the cutout 170 is easily torn by a straw. In the embodiment of the present invention, the two cutting lines 173 cross at right angles to each other. Let's do it.

The center point 174 is an intersection created at the center when two perforations 173 intersect, and the PET layer 110 is not laminated when the end of the straw is applied to the center point 174 by applying an external pressure. The perforated line 173 including the non-long-term center point 174 exposes the aluminum foil layer 120 and the PE layer 130 to directly receive a tensile force.

The aluminum foil layer 120 and the PE layer 130 having a tensile force are easily stretched to some extent, but easily ruptured and cut along the cut line 173, and the body 100 between the cut portions of the cut line 173. A penetrating part penetrates the penetrating part, and the penetrating part is a straw insertion hole into which a straw is inserted.

In addition, when the diameter of the straw is relatively thin, the cutting line 173 is cut by the center point 174, but when the diameter of the straw is large, the cutting line 171 is cut and the cutout 170 is the straw as in the first embodiment. When inserted into the interior of the body 100 with the insertion, the shortest straight portion connecting the cutting end 172 is inserted into the interior folded so that the cutout 170 is separated from the body 100 falls to the contents Will be prevented.

As described in detail above, the beverage packaging container of the present invention is made by cutting a cut section formed with a single or a plurality of cutting lines with a straw so that the straw is inserted into the container, so that the straw can be easily cut without having to put a lot of force on the straw.

In addition, the beverage packaging container of the present invention allows a plurality of cutting lines formed in the cutout portion to be generated by removing the PET layer by the laser, so that it is not necessary to attach a separate layer and thus the manufacturing process is simple. Can save.
