JP6379800B2 - Paper tab member and beverage container provided with the same - Google Patents

Description

  The present invention relates to a paper tab member and a beverage container provided with the same.

  There is known a beverage container in which a drinking hole opened in the top is sealed with a tab member. The mouthpiece is opened by peeling the tab member from the top.

  When the entire tab member is in contact with the top of the container, it is difficult to pinch the tab member because it is difficult to put nails or fingers on the edge of the tab member. Patent document 1 describes what formed the hole in the tab member, and formed the cut-up in order to make it easy to pinch the tab member when peeling off the tab member.

Japanese Utility Model Publication No. 4-106224

  However, since the tab member for sealing the drinking mouth is relatively small (the area is small), it is difficult to make a hole in the tab member or to form a large cut.

  It is an object of the present invention to make it easier to pinch the tab member, thereby improving the opening property when the tab member is peeled off.

  The present invention provides a tab member, particularly a paper tab member based on paper. The paper tab member according to the present invention is used together with a container having an opening, and is adhered to the entire periphery of the opening on the outer surface of the container so as to close the opening. Is provided, a stamped mark is formed in the vicinity of the tip edge of the non-adhered knob, and a jumping part is formed around the stamped mark.

  The paper tab member according to the present invention is used together with a container in which an opening is formed, and closes the opening formed in the container. To close the opening, the paper tab member is adhered to the entire periphery of the opening on the outer surface of the container. An unbonded knob is provided at the tip of the paper tab member that closes the opening, and a mark is made near the tip edge of the unbonded knob. Here, the vicinity of the leading edge means a place slightly away from the leading edge. In other words, it means that a mark is made at a slight distance from the tip edge of the unbonded knob.

  The paper tab member uses paper as a base material as described above. For this reason, when the paper tab member is locally pressed, the pressed range is recessed and the state is maintained. In other words, the paper tab member is pressed. Furthermore, when a paper tab member is pressed, a jump (swell) occurs around it. As described above, the mark is applied near the tip edge of the non-adhered knob and the surrounding area jumps up, so that the tip edge of the knob is separated (floated) from the outer surface of the container. Since there is a gap between the tip edge of the knob and the outer surface of the container, it is easy to put a nail or fingertip there, and it is easier to turn the knob. Since the turned knob can be easily pinched with a finger after that, the opening operation (peeling of the paper tab member) becomes easy. Note that the bonding range of the paper tab member bonded to the container does not jump up. The bounce-up portion is generally formed around the entire area of the pushing mark, but there may be a portion where there is no bounce-up portion or a small portion due to the presence of the adhesion range.

  The paper tab member has, for example, a rectangular shape whose longitudinal direction is the peeling direction of the paper tab member. The gap due to the above-described jumping is formed at the leading edge in the direction (short direction, width direction) orthogonal to the longitudinal direction of the paper tab member.

  In one embodiment, the imprint mark is made at the center in the width direction of the unbonded knob. A gap can be secured in a well-balanced manner on both sides of the mark at the tip edge of the unbonded knob.

  The present invention also provides a beverage container including the paper tab member described above. A beverage container according to the present invention comprises a cylindrical barrel, a top that closes the upper end of the barrel, and a bottom that closes the lower end of the barrel. The mouth is closed by a paper tab member adhered to the entire periphery of the drinking mouth on the outer surface of the top portion, and an unadhered knob is provided at the tip of the paper tab member. In addition, a pressing mark is formed in the vicinity of the tip of the non-adhered knob, and a jumping part is formed around the pressing mark. As described above, since a gap is formed between the top of the container and the non-adhered knob at the flip-up part, it is easy to put a nail or a fingertip there, and the paper tab member is easy to peel off from the top of the container. . The beverage containers of the present invention include containers made of various materials such as paper containers, resin containers, and metal containers.

  In one embodiment, a convex protrusion is formed on the outer surface of the top portion of the container, and a part of the non-adhering knob is riding on (covered on) the convex protrusion. ). A gap is formed between the unbonded knob and the top of the container by riding on the convex protrusion. It becomes easier to put a nail or a finger on the tip edge of the knob, and the knob can be turned more easily. Since the convex protrusion is formed on the top of the beverage container, a relatively large and firm convex protrusion can be formed.

  Preferably, a pair of convex protrusions are formed on each side of the unbonded knob. A gap can be formed in a well-balanced manner between the unbonded knob and the top.

  In another embodiment, a concave depression is formed on the outer surface of the top, and the concave depression is located near the tip of the unbonded knob. It is possible to make it easier to put the nail or the fingertip into the tip edge of the picking portion by letting the nail or the fingertip into the concave depression. Since the concave depression is formed on the top of the beverage container, a relatively large and firm concave depression can be formed.

  The concave depression is formed at a position where the nail or fingertip can be submerged and the nail or fingertip can be applied to the tip edge of the tab member's knob, that is, near the tip of the unbonded knob. Is done. In one embodiment, the unbonded knob covers at least a part of the concave depression. In a mode in which the unadhered knob part covers a part of the concave depression part, the nail or the fingertip can be brought into the concave depression part from a place not covered by the knob part. The unadhered knob may cover the entire concave depression. When the knob part covering the concave depression part is pushed toward the concave depression part, the edge part of the knob part is warped, so that it is easy to put a nail or a finger on the tip edge of the knob part even in this mode.

  In a preferred embodiment, the concave depression is formed between the pair of convex projections spaced from each of the pair of convex projections. A relatively wide gap can be secured between the top and the non-adhered knob by both the convex protrusion and the concave depression.

  Hereinafter, a paper tab member and a container including the same according to the present invention will be described in detail with reference to the drawings.

  1 to 4 show a beverage paper container of the first embodiment. FIG. 1 is a perspective view of a beverage paper container. FIG. 2 is a plan view of the beverage paper container. FIG. 3 is an enlarged perspective view of the top of the beverage paper container. 4 is an end view of a tab portion of a paper tab member and a top portion of the container, which will be described later, along the line IV-IV in FIG. In FIG. 4, the thickness of each layer of the paper tab member is drawn with emphasis for easy understanding.

  The beverage paper container 1 includes a cylindrical body 11, a circular top 12 that closes the upper end of the body 11, and a circular bottom 13 that closes the lower end of the body 11. The body part 11, the top part 12 and the bottom part 13 are made of, for example, paper as a main component and polyethylene (PE) laminated on the inner surface, and have watertightness. Polyethylene, aluminum (AL) or the like may be laminated on the outer surface. For example, a laminated structure in which polyethylene, paper, polyethylene, aluminum, and polyethylene are laminated in this order from the inner surface to the outer surface is used. The top portion 12 is located slightly below the upper edge of the body portion 11, and the periphery of the top portion 12 is surrounded by the upper end portion (peripheral wall) 11 </ b> A of the body portion 11.

  A drinking mouth (a straw insertion opening) 14 is opened in the top 12. The drinking mouth 14 is formed in a drop shape (tear drop shape) as viewed from above, that is, tapered toward the center of the top 12. A drinking mouth 14 opened in the top 12 is closed by a rectangular paper tab member 21.

  The paper tab member 21 has paper as a base material, and has a thermoplastic resin, preferably a polyolefin resin (for example, polyethylene (PE)) laminated on the inner surface thereof. The paper tab member 21 is bonded to the outer surface of the top portion 12 by heat welding using a thermoplastic resin laminated on the inner surface of the paper tab member 21. An adhesion range 31 between the paper tab member 21 and the top portion 12 is indicated by a one-dot chain line in FIG. That is, the paper tab member 21 is bonded to the outer surface of the top portion 12 when the bonding range 31 is heated and pressed toward the outer surface of the top portion 12. The adhesion range 31 of the paper tab member 21 surrounds the entire periphery of the drinking mouth 14 opened in the top portion 12 and is tapered in the same direction as the tapered drinking mouth 14. The paper tab member 21 can be bonded to the top portion 12 using an adhesive instead of heat welding.

  At the tip end portion of the paper tab member 21, there is an unbonded range that is not bonded to the outer surface of the top portion 12. Hereinafter, the unbonded tip portion of the paper tab member 21 is referred to as a “pick portion 21A”.

  A push pin (not shown) is pressed against the unbonded knob 21A at the tip of the paper tab member 21, and a relatively narrow range is pressed. When the unadhered knob 21A is pressed using a push pin, the knob 21A has a stamp mark (valley) 21C. As a push pin pressed against the knob 21A, for example, a push pin having a cylindrical outer shape and having a tip slightly curved outward can be used. A mortar-shaped imprint 21C that is circular as seen from the plane is formed on the knob 21A. The imprint may not be circular when viewed from the plane, but may be rectangular, triangular, elliptical, or other shapes. In any case, a stamp mark having a shape corresponding to the shape of the push pin pressed against the knob portion 21A is applied to the unbonded knob portion 21A.

  The stamped mark 21C is slightly attached to the inner side of the front edge 21B of the paper tab member 21, for example, about 1 mm, and the size (diameter) is the length in the width direction of the paper tab member 21 (the length of the paper tab member 21). The length of the paper tab member 21 in the width direction is about 1/3 to 1/6 of the length in the direction orthogonal to the direction). That is, the unadhered knob portion 21A hardly expands in front of the mark 21C (direction toward the tip edge 21B), and on the other hand, it is relatively long on both sides (left and right) (direction toward both edges) of the mark 21C. An unbonded knob 21A spreads over the distance.

  When a pressing mark 21C is made on the paper tab member 21 by pressing the push pin against the knob 21A, at the same time, a jumping (swelling) occurs in the peripheral portion of the pressing mark 21C of the paper tab member 21 (FIGS. 2, 3). (Indicated by reference numeral 21D in FIG. 4). As described above, the non-adhered knob 21A spreads over a relatively long distance on both sides (left and right) of the press mark 21C, and the other side is not bonded to the front of the press mark 21C (direction toward the tip edge 21B). There is almost no spread of the knob 21A. Further, an adhesion range 31 exists behind the pushing mark 21C (in the direction toward the drinking mouth 14), and is adhered to the top 12 of the container 1. For this reason, the jumping in the unbonded knob 21A is greatly generated on both sides of the pushing mark 21C. When the unbonded knob 21A jumps up, the unbonded knob 21A is separated from the top 12 of the container 1 at that portion. As described above, since the pushing mark 21C is formed near the tip edge 21B, a gap is formed between the tip edge 21B of the knob 21A and the top portion 12.

  Referring to FIG. 4, the unbonded knob 21 </ b> A once jumps (swells) (bounces 21 </ b> D) and gradually curves downward on the way to the side edge on each side of the pressing mark 21 </ b> C. This downward curve is caused by applying heat to the bonding area 31 in order to heat-weld the paper tab member 21 to the top 12 of the container 1. Referring to FIG. 4, a thermoplastic resin 23 is laminated on the inner surface of paper tab member 21 including knob 21A. Although heat is not directly applied to the unbonded knob 21A, the heat when the bonding area 31 is heated is also transmitted to the unbonded knob 21A, and thus the thermoplastic resin also in the area of the knob 21A. 23 contracts and the side end portion of the unbonded knob 21A is bent downward due to this effect.

  As shown in FIG. 4, an anti-heat sealant 24, such as a fluorine-based resin or a silicone resin, is applied to the outermost layer (the lower layer of the thermoplastic resin 23) where the inner surface of the unadhered knob 21A is the outer layer. That is, the unadhered knob portion 21A has a three-layer structure in which the paper base material 22, the thermoplastic resin 23, and the anti-heat sealant 24 are laminated in this order from the outer surface toward the inner surface. Since the anti-heat sealant 24 is laminated on the inner surface of the unadhered knob 21A, even if it is pressed with a push pin while heat is transmitted to the unbonded knob 21A as described above, The portion 21A (the portion of the pressing mark 21C) is not adhered to the outer surface of the top portion 12. Needless to say, the anti-heat sealant 24 is not applied to a range (adhesion range 31) that is not the knob 21A of the paper tab member 21.

  As described above, since the tip edge 21B of the knob 21A of the paper tab member 21 jumps up (outward) away from the outer surface of the top 12, the gap between the tip edge 21B of the knob 21A and the top 12 is increased. A gap is formed, and a nail or a fingertip can be easily put on the tip edge 21B of the knob 21A from this gap, and the knob 21A can be easily turned. The paper tab member 21 is peeled off by pinching the turned knob 21A with a finger and pulling it in the direction of the drinking mouth 14. Since the adhesive range 31 for adhering the paper tab member 21 to the outer surface of the top portion 12 is provided in a tapered manner, the paper tab member 21 can be peeled off with a light force.

  FIG. 5 is a plan view of the beverage paper container of the second embodiment. 6 is an end view of the tab portion of the paper tab member and the top portion of the container along the line VI-VI in FIG. In FIG. 6, detailed illustration of the laminated structure of the tab portion of the paper tab member (see FIG. 4) is omitted. The same members as those in the beverage paper container 1 of the first embodiment are denoted by the same reference numerals, and redundant description is omitted.

  The outer surface (front surface) of the top portion 12 of the container 2 of the second embodiment has a debossed portion (concave recess portion) 15 that is recessed inward from the outer surface of the top portion 12 as a reference surface, and outward. A pair of embossed portions (convex protrusions) 16L and 16R projecting from each other are formed away from the drinking mouth 14.

  The debossed portion 15 is formed in a rectangular shape in a direction substantially perpendicular to the direction of the tapered drinking mouth 14 on the extension line (tapered direction) of the tapered drinking mouth 14. The length in the longitudinal direction of the debossed portion 15 is slightly shorter than the width of the paper tab member 21 (the knob portion 21A) (the length in the direction perpendicular to the longitudinal direction of the paper tab member 21). The depth of the debossed portion 15 is, for example, about 0.2 to 0.9 mm. The depth of the debossed portion 15 is appropriately adjusted according to the thickness or the like of the top portion 12 of the container 2.

  The embossed portions 16L and 16R are formed on the left and right sides of the debossed portion 15 with a distance from the debossed portion 15, and the debossed portion 15 is located between the two embossed portions 16L and 16R. The embossed portions 16L and 16R are formed to be slightly elongated in the direction along the direction of the tapered drinking mouth 14. The height of the embossed portions 16L and 16R is, for example, about 0.2 to 0.9 mm. The heights of the embossed portions 16L and 16R are also adjusted as appropriate according to the thickness of the top portion 12 of the container 2.

  The debossed portion 15 is formed by pressing the pressing die from the outside of the top portion 12, and the embossed portions 16L and 16R are formed by pressing the pressing die from the inside of the top portion 12, respectively.

  The paper tab member 21 extending toward the debossed portion 15 and the embossed portions 16L and 16R has an unadhered knob portion 21A at the tip portion covering a part of the debossed portion 15, and the left and right ends thereof at the embossed portions 16L and 16R. Each rides (covers, is on).

  As described above, the left and right ends of the unadhered knob portion 21A of the paper tab member 21 ride on the pair of embossed portions 16L and 16R formed on the top portion 12, respectively. There is a gap between the knob part 21A and the heaven part 12. Further, since the tip edge 21B of the knob 21A is located above the debossed portion 15, the nail or fingertip that has entered the debossed portion 15 can be easily applied to the tip edge 21B of the knob 21A. Further, the knob portion 21A of the paper tab member 21 jumps up as described above (bounce-up portion 21D). By combining the embossed portions 16L and 16R, the debossed portion 15, and the raised portion 21D, the tip edge 21B of the picked portion 21A of the paper tab member 21 can be easily put on the nail or the fingertip. You can turn. The paper tab member 21 is peeled off by pinching the turned knob 21A with a finger and pulling it in the direction of the drinking mouth 14.

  The tip edge 21B of the unbonded knob portion 21A of the paper tab member 21 is positioned above the debossed portion 15, that is, it is not always necessary to cover a part of the debossed portion 15 with the knob portion 21A. You may let them. Even in this case, the nail or the fingertip that has entered the debossed portion 15 can be applied to the tip edge 21B of the picked portion 21A. Alternatively, the entire debossed portion 15 may be covered with the unadhered knob portion 21A of the paper tab member 21. When the knob portion 21A is pushed toward the debossed portion 15, the knob portion 21A warps, so that the nail or finger can be easily applied to the tip edge 21B of the knob portion 21A in this mode.
