The present invention generally relates to a packaging container, and in more detail, relates to a paper container for putting beverages or other liquids such as milk and juice. More specifically, the Bowon devise relates to a paper container known as a gable top type, which is provided with a double inclined saw on a box-shaped body, and contains liquid from one side of two inclined surfaces. There is an outlet to drain the water.

A known method of pouring liquids from the gable top is to force the opposing sides of the sealed ridge of the gable top apart from each other and open. This method is inconvenient because it requires considerable human power. In addition, there is a hygienic problem to directly operate to pour liquid from the gable top.

In order to solve the above problems, the use of plastic injection ports, in particular liquor, soy sauce, etc. in a plastic container has been proposed. This outlet is attached to one side of the inclined surface of the gable top, so that the sealed ridge of the gable top does not have to be unduly opened to pour out the contained liquid. However, the ejection outlet configured as in the prior art has two members, and is mainly composed of the ejection surface portion and the lid. Therefore, the user has had to remove the hem lid and then tear off the sealed portion of the ejection surface.

The construction of the two members was expensive because the prior art spouts required considerable time and force to open, as well as two different moldings in their manufacture. The attachment of the spouts of the two members located in the gable top paper container was not easy.

Nevertheless, the present invention seeks to solve the conventional problems in the manufacture and use of a gable-top paper container by providing a novel spout integrally composed of one member.

Briefly described, the Bowon devise provides a gable top paper container for containing liquid water, which consists of a sealed top and a gable top sealing the top of the box-shaped body. The gable top has two inclined surfaces, one side of which is formed with an opening. These openings are sealed as spouts of any configuration, including lids with protruding pull tabs.

The injection port of the above-described configuration can be manufactured by integral injection molding of plastic. Then, in use, the pull tab can be pulled and torn to open the lid. Preferably, the pull tab is integrally formed with the hook and the hook is hooked to the sealed ridge of the gable top to keep the lid open when the lid is torn open. After the required liquid has been drained, the hook is released from the ridge, the lid is closed, and left closed until it is poured out from the paper container.

In general, two basic types are conceivable. One type has a substantially ejection face with a flange and is closed by a lid that can tear the outer end of the ejection face. The flange at the inner end of the ejection surface portion is welded to the inner side of the edge of the gable top forming the opening. The other form is a flat plate attached to the outside of the edge of the gable top. Either way, the lid can be easily opened by pulling the pull tab away from the ejection surface or gable top to partially tear the lid. Therefore, when pouring the liquid, there is no need to touch the ejection surface portion of the ejection or paper container which the liquid water comes into contact with. In addition, the hook at the end of the lid is caught on the ridge of the gable top to keep the lid fully open while being partially torn open and hinged to the rest of the ejection outlet, so that the ejection of the liquid is not inhibited.

Of course, the spout of the unitary constitution according to the present invention is much easier to manufacture than the spout of the design of the two members according to the prior art, and the manufacturing cost is lower. It is also easy to attach the spout in place of the gable top. This is because it can be easily welded by heat or ultrasonic waves to a cardboard to make a paper container.

Gable top paper container according to the present invention is suitable as a packaging container for milk, juice and the like. The beverage paper containers are all consumed in a relatively short time after the lid is opened. These paper containers usually do not open or close frequently, nor are they too tightly closed. Such an improvement in the ejection outlet is very suitable for use in the paper container. This is because the configuration is simple, the manufacturing cost is low, it is easy to use, and it is hygienically good.

Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The gable top paper container 20 of the present invention is shown in its entirety in FIG. The paper container 20, which is mainly made of cardboard, is composed of a box-shaped body 22 having a conventionally sealed bottom 24. At the upper end of the box-shaped main body 22, there are two inclined gable tops 26, and two opposing inclined surfaces 28 provided with ridges 30 sealed like second tiles. One side of the inclined surface 28 of the gable top 26 has an opening 32 formed in its approximately center. The opening 32 is sealed by the spout 34 which constitutes the main part of the present invention. The spout 34 is formed integrally with a plastic material such as polyethylene or polypropylene.

As shown in FIGS. 2-6, the spout 34 is provided with the spout surface part 36 which protrudes outward from the opening 32 of the gable top 26. As shown in FIG. This ejection surface portion 36 is opened at the inner end of the paper container 20 and closed at the outer end by a lid 38 formed to be torn. The pull tab 40 protrudes outwardly, ie upwards from the lid 38, at its end with a hook 42 towards the ridge 30 of the gable top 26.

The limit stop 44 protruding from the pull tab 40 in the opposite direction to the reach 30 of the gable top is caught by the outer end of the ejection surface portion 36 when the lid 38 is torn open, and then closed again. To prevent it from being pressed too much. In addition, the limit stop 44 reinforces the pull tab 40, and is effective in increasing its rigidity. The limit stop 44 should not protrude too far from the ejection surface portion 36 so as not to impede the ultrasonic or thermal welding means described later. The limit stop 44 is preferably formed spaced slightly apart from the lid 38 to secure the lid closed after being torn open. This spacing is approximately equal to the thickness of the lid 38.

The spout 34 is also formed to include a mounting flange 46 at the inner end of the spout surface 36. The mounting flange 46 is watertightly welded to the inner surface of the edge of the gable top 36 forming the opening 32.

Further, the spout 34 is provided with a plurality of, typically three or four lugs 48 protruding laterally from the spout surface portion 36 at positions spaced on the periphery. These lugs are for use in temporarily holding the spout 34 at the position of the gable top 36 necessary for the welding of the mounting flange 46. The lug 48 must be spaced from the mounting flange 46 by a distance sufficient to engage the edge of the opening 32 of the gable top 26 between it and the mounting flange. In general, the spacing between each lug 48 and the mounting flange 46 should be about four to five times the thickness of each inclined surface 28 of the gable top 26, so that the lug is the inclined surface of the gable top 26. When attaching the spout 34 to 28, the edge of the gable top can be easily fitted. This clearance is actually 1.5 to 2.0 mm. When this gap is less than this range, the lug will not be caught on the gable top edge. When this interval is larger than the above range, the spout is inclined at the gable top, making it difficult to properly weld the mounting flange 46.

As shown in FIG. 7, the distance S between one lug (48 ′ in FIG. 7) and the mounting flange 46 located at the straight end portion (leftward in FIG. 7) of the ejection surface portion 36. ₁ ) should be greater than the distance S ₂ between each other lug 48 and the mounting flange 46 arranged on the curved portion of the ejection surface. Thus, for example, when the spacing S ₂ is 0.1 mm larger than the thickness of the cardboard making the paper container 20, the spacing S ₁ is 1.5 to 2.0 mm larger than the thickness of the cardboard. This difference between the spacing S ₁ and the spacing S ₂ is desirable, which is parallel to the ridge 30 of the gable top, and that of the gable top 26 against the straight end of the ejection surface 36. The straight edge is more flexible than the other gable tops forming the opening 32, as described below.

As shown in the plan view of FIG. 4, the ejection surface portion 36, the lid 38, and the mounting flange 46 of the ejection opening 34, including the opening 32 formed to be sealed, are all in the shape of a baseball base, and the straight end portion is The end that faces the ridge 30 of the gable top and protrudes (in fact, is reasonably rounded) at an angle is opposite the ridge of the gable top.

In particular, in Figs. 3 and 4, the lid 38 formed to be torn has a first groove 50 formed inward from the top of the straight end when the ejection surface 36 is sealed, and an upper end of the ejection surface portion. It is formed by the second groove 52 which extends from the end which protrudes with the angle of the upper end of the extraction surface part along the two opposing sides of to the opposing end part of the 1st groove | channel 50. The second groove 52 is deep enough that the lid 38 can be torn along the second groove by pulling the pull tab 40. However, the first groove 50 is made so shallow that the lid 38 does not tear along the groove. Thus, the first groove 50 is used for hinge connection between the torn lid and the ejection surface portion. Thus, the lid 38 has a hinge end portion at a straight end portion of the upper end of the ejection surface portion and an end portion formed so as to tear at the protruding portion at an angle. The pull tab 40 is located in the vicinity of the torn end of the lid 38.

The depth of the grooves 50 and 52 should be determined according to the thickness of the lid 38. The remaining thickness T ₁ (FIG. 3) of the upper end of the ejection surface of the first groove 50 should be sufficient to withstand the opening and closing of the lid 38 repeatedly in the use of such a gable top paper container 20. . The preferable range of the thickness T ₁ is 0.4 to 0.5 mm. On the other hand, the remaining thickness T ₂ of the ejection surface portion of the second groove 52 should be thin enough to easily tear the lid 38, but the ejection opening 34 is attached to the gable top 26, or It should not be so thin that it tears while carrying the paper container 20. Therefore, the preferable range of the thickness T ₂ is 0.2 to 0.3 mm.

The outlet 34 of the improved form is configured to be attached in place of the paper container 20 before the paper container 20 is formed in the shape of a cable top box of FIG. The spout surface 36 of the spout 34 has a gable top 26 until the lug 48 above it emerges from the opening and the edge of the gable top 26 is caught between the lug and the mounting flange 46. It can be inserted from the inside through the opening 32 of the. The mounting flange 46 can be welded to the inner surface of the edge of the gable top 26 by heat or ultrasonic waves.

As shown in FIG. 7, the distance S ₁ between the lug 48 ′ and the mounting flange 46 at the straight end of the ejection surface portion 36 is between the other lug 48 and the mounting flange. Is 0.5 to 1.0 mm larger than the spacing (S ₂ ) of. Thus, even if the straight edge of the gable top caught by the lug 48 'is more prone to bend than the edge of the other gable top caught by the lug 48, all of the lugs 48 and 48' are defined by the opening ( At the same time, the edge of the gable top is caught between the lug and the mounting flange 46 simultaneously. The spout 34 can be easily attached onto the gable top 26 in this manner.

The ejection surface portion 36 of the ejection opening 34 is inclined as it projects from the open inner end toward its sealed outer end. This inclination is intended to allow the ejection surface portion 36 to be quickly inserted through the opening 32 of the gable top. This inclination allows the ultrasonic horn or the heat welding head to easily access the outer circumferential surface of the gable top edge around the opening 32, so that the mounting flange can be more easily welded to the gable top 26.

The gable top type paper container 20 may fill a desired beverage or other liquid water, and then attach the spout 34 in place and close and seal the gable top by the above known method.

It is possible to pour out the liquid contained in the cap 38 of the spout 34. The lid 38 can be opened by pulling the pull tab 40 or by pulling the pull tab towards the ridge 30 of the gable top. The rigidity is reinforced by the limit stop 44 so that the pull tab 40 transmits a sufficient force against the tear end of the lid 38. When intensively applying force to the tear end of the lid 38, tearing the upper end of the ejection surface portion of a part of the deep groove 52 in the tear end of the lid, and then pulling the pull tab 40 slightly, The lid 38 is torn along the deep grooves 52, and roughened portions are formed at opposite edges of the lid and opposite edges of the torn ejection surface. To the opposite end of the shallow groove 50 at the hinge end of the lid 38.

In this way, the fully open lid 38 is rotatable on the hinge end of the ejection face 36. The lid 38 latches the hook 42 onto the sealed ridge 30 of the gable top 26 and remains fully open, as indicated by the dashed-dotted line in FIG. The liquid can be poured out from the open ejection face portion 36 of the ejection outlet 34.

After the desired amount of liquid has been poured out, the gable top can be closed again by releasing the hook 42 from the ridge 30 and pressing the lid 38 to the top of the ejection surface 36. As described above, the tearing of the lid creates a roughened portion around the lid and on the upper edge of the ejection surface portion 36. Therefore, when the lid 38 is closed again, the roughened portion around the lid is caught with the roughened portion of the upper edge of the ejection surface portion, and the lid is closed without being spring-opened by the elasticity of the hinge end portion.

The user may apply too much force to close the lid again. The limit stop 44 on the pull tab 40 then catches on the top of the spout surface 36 to prevent the lid 38 from being too pressed into the spout surface. It has been described that the limit stop 44 is slightly spaced upward from the upper end of the ejection surface portion 36, that is, outward. Thus, by pressing the lid into the ejection surface portion by an interval smaller than the gap between the limit stop 44 and the upper end of the ejection surface portion, the lid 38 is reliably prevented from opening the lid incorrectly by the rough portions caught between the lid and the ejection surface portion. Is locked.

8, 9 and 10 illustrate some variations of the spout 34 described above. In general, the modified spout 134 is configured to be attached to the gable top 26 of the paper container of FIGS. 1 and 2 instead of the spout 34.

The spout 134 has two hooks 142 and 160 and is different from the spout 34 in that it is formed integrally with the end of the pull tab 40. The first hook 142 is substantially the same as the hook 42 of the above embodiment, which is directed towards the ridge to engage the sealed ridge of the gable top when the lid is torn open. The second hook 160 is on the opposite side of the ridge of the gable top. When the lid is torn open and then closed again, the lid is caught by the outer end of the ejection surface portion when the lid is too pressed into the ejection surface portion. Other details of the configuration of the spout 134 are the same as those described in the above embodiment.

The two hooks 142 and 160 on the pull tab 40 protruding in opposite directions from the top are additional to hold the pull tab stronger than when there is only one hook as in the case of the main spout 34. Has a purpose.

The user may grasp both the hooks 142 and 160 to open the lid 38 and pull the pull tab 40.

As the lid continues to be pressed further, the lid 38 may be forced into the ejection surface 36 beyond the limit defined by the limit stop 44 on the pull tab 40. Then, as shown in FIG. 10, the second hook 160 is caught by the upper end of the ejection surface portion 36, thus preventing the lid from being further pressed into the ejection surface portion or the paper container. It can be seen that the lid 38 of the spout 134 is double in order to prevent it from being forcibly pressed into the spout surface 36.

11, 12 and 13 show another spout 234 attached to the gable top of the paper container 20 instead of the spout 35. The spout 234 is characterized in that the notched groove 262 is formed at the midpoint of the hook 42 and the limit stop 44 of the pull tab 40. The notch groove 262 extends laterally with respect to the pull tab 40, and the thickness of the intermediate point of the hook 42 and the limit stop 44 is made small. The other configuration of the spout 234 is the same as the other details of the spout 34 described earlier.

The notch groove 262 allows the pull tab 40 to be folded so that the lid 38 can be undesirably pressed into the ejection surface 36. The lid 38 can be closed again after tearing off the lid as in the thirteenth degree by holding the hook of the upper end of the pull tab 40. When the torn lid 38 is closed again with great force, the limit stop 44 on the pull tab 40 is caught by the upper edge of the ejection surface 36. If more force is applied to the pull tab 40, the pull tab will fold and bend towards the ridge of the gable top as in the thirteenth degree. Then, the force exerted on the pull tab 40 will be substantially released on the lid 38 and the limit stop 44, and thus remain in the position of FIG. 13, and the lid will properly close the open top of the spout 36.

As described above, the collapsible pull tab of the spout 234 can be regarded as an alternative to the double or pull tap of the pull tab 40 of FIGS. 8 to 10.

In addition, since the notch groove 262 allows the pull tab to be folded as described above, such a notch groove or a corresponding groove may be formed on both sides of the pull tab. The spout 234 with the pull tab 40 that is foldable has the advantage of enabling the use of a relatively soft plastic material.

14 and 15 show another embodiment of the spout 234 according to the present invention, which is also used for the paper container 20 of FIGS. 1 and 2 instead of the spout 34. Suitable. The spout 334 protects the contained liquid from deterioration or decay quickly.

One of the things you need to pack a product that is susceptible to deterioration is the ability to keep it as long as possible under the right conditions. When the outlet of the paper container according to the present invention is molded from polyethylene or a transparent or translucent plastic material, light passes through it to easily change the filled liquid. Most countries define the range of plastics that can be used as food packaging, thus prohibiting the use of additives such that light cannot pass through the food packaging.

Therefore, in the spouts 334 of FIGS. 14 and 15, the outer surface of the lid 38 is an uneven surface in the shape of an oblique line, as indicated by 346. The cross-shaped uneven surface 364 of the lid 38 reflects the light source thereon, and is effective to substantially reduce the intensity of light rays passing through the lid. The other configuration of the spout 334 is substantially the same as the other details of the spout 34 in FIGS. 1 to 7.

Of course, the inner surface as well as the outer surface of the lid 38 may also be a concave-convex surface to prevent the passage of light to the top. Further, as shown in FIG. 16, the ejection face portion 36 of the ejection outlet can also serve the same purpose as the uneven surface as indicated by the position 366. Such unevenness of the spout can be easily performed by processing the required molding surface or surface.

Another embodiment of the spout 434 shown in FIGS. 17, 18 and 19 is formed to include a reinforcement 468 at the junction between the lid 38 and the pull tab 40. The reinforcement 468 extends along the width of the pull tab 40 and is located opposite the pull tab facing the hinge end of the lid 38. The other configuration of the spout 434 is substantially the same as the other details of the spout 34 in FIGS.

The reinforcement 468 is used to bond the pull tab 40 to the lid 38 without damage as well as to prevent the pull tab from bending when the lid 38 is torn open and then closed again. If the pull tab 40 is too flexible, the limit stop 44 installed thereon may be directed upward when the lid 38 is closed by pressing the pull tab again. Therefore, the limit stop 44 is not caught on the upper end of the ejection surface portion 36, the lid is pressed into the ejection surface portion, and the reinforcement portion 468 eliminates the possibility.

A relatively thin rib shaped reinforcement portion 468 'is shown in FIG. 20, which is also formed in the engaging portion between the lid 38 and the pull tab 40. As shown in FIG. This rib acts like the reinforcement 468 of FIGS. 17-19. However, it is not preferable to install these two ribs at positions away from each other, because foreign matter accumulates therebetween.

21, 22 and 23 show another embodiment of the spout 534, the pull tab 40 being joined to the lid 38 by an axis diameter portion 580. FIG. . The other structure of this spout 534 is the same as the detail of the spout 34 of FIGS.

When pulling the pull tab 40 to tear the lid 38 open, the shaft 570 concentrates the pulling force on the lid 38. As a result, when the pull tab is directly bonded to the lid as in all the above embodiments, the lid 38 can be opened with less force.

Another embodiment of the spout 634 shown in FIG. 24 combines the features of the spout 434 of FIGS. 17-19 and the spout 534 of FIGS. 21 and 23. The pull tab 40 is joined to the lid 38 by an axis diameter portion 670 having a reinforcement portion 668 formed at the hinge end portion. The advantages of these features are described above.

Another embodiment of the spout 734 is shown in Figs. 25, 26 and 27, which is different from all of the above embodiments with no extraction surface. The spout 734 is substantially flat and consists of a relatively thick 738 with the pull tab 740 protruding outwardly, with a hook 724 at the end of the pull tab 740, and the mounting flange 746 has a lid ( 738) is excreted around. Both the lid 738 and the mounting flange 746 have a baseball base shape as shown in the plan view of FIG. The lid 738 is attached to an opening 32 of a shape corresponding to one inclined surface 28 of the gable top 26. The mounting flange 746 is welded to the adjacent edge of the gable top. The mounting flange 746 has a groove 772 formed therein, which is formed in the vicinity of the straight end portion on the ridge 30 side of the gable top. The groove 772 extends parallel to the ridge 30 of the gable top. The pull tab 740 is disposed at an angle at the end of the lid 738 opposite the ridge 30 of the gable top.

As such, the pull flange 740 is pulled out and at the same time the mounting flange 746 is torn off from the gable top 26, and a part of the pull tab is torn at the closest part of the pull tab to continue tearing to both ends of the groove 772. A portion of 746 is folded in groove 772. The pull tab 740 is hung on the ridge 30 of the gable top as shown by the dashed-dotted line in FIG. 25 to pour out the liquid contained through the opening 32 of the gable top.

Unhook the hook 742 on the pull tab 740 from the ridge 30 of the gable top to close the opening 32 of the gable top, and attach the lid 738 to the opening of the gable top with a portion of the mounting flange 746. Can be closed. The lid 738 can be closed stably by friction with the edge of the gable top forming the opening. Then, the mounting flange 746 is to be supported against the gable top.

The edge of the gable top forming the opening 32 cannot be completely closed by this spout 734 after the lid 738 is torn open. However, especially if the paper container is consumed all the other beverages such as milk, juice, etc. in a relatively short time does not cause any problem. Other outlets disclosed herein, which are deposited on the inside of the gabletop, can be used for more permeable liquids such as liquor and soy.

As described above, the embodiments of the present application have been described in detail, but the embodiments described herein are merely examples, and do not impose any limitation on the present invention. You can make changes. For example, the spout does not have to be a baseball base, as in a plan view, and may be a circle, a hexagon, a triangle, a hexagon, or the like. In addition, the two grooves 50 and 52 formed in the lid 38 need not be cut off at the inner surface of the sealed outer end of the ejection surface portion 36. Alternatively, two grooves deeper in total depth than the first grooves 50 may be formed on both the inner and outer surfaces of the outer edge of the ejection surface portion.
