Hereinafter, an embodiment embodying the spout of the present invention will be described with reference to FIGS.
As shown in FIG. 1, the spout S of the present embodiment is attached to a cup C that contains a beverage, and is used to tilt the cup C and drink the beverage. The cup C has a configuration in which a cup body B containing a beverage and an upper opening of the cup body B are sealed with a tearable film F such as polyethylene terephthalate (PET). The cup body B has a cup collar C1 protruding outward at the opening. The upper surface of the cup collar C1 has a width of several mm, and the periphery of the film F is stretched on the cup C by being fixed to the upper surface of the cup collar C1 by heat welding or an adhesive. Yes. This spout S is fixed to a part of the film F before drinking and can be removed from the cup C after use. When the spout S is attached to the cup C, the surface facing the radially inner side of the cup C is the front surface, the radially outer surface is the back surface, the surface that is the upper surface side of the film F is a flat surface, and the cup bottom surface is the cup bottom surface side. The surface facing is the bottom surface.

  The spout S includes a first fixing portion 11 that is fixed to the edge portion of the cup C, a second fixing portion 12 that is fixed to a position opposed to the fixing position of the first fixing portion 11 via the cup opening, And a connecting portion 13 that connects the first fixing portion 11 and the second fixing portion 12. The spout S is made of resin such as polypropylene (PP), polyethylene terephthalate (PET), polyethylene (PE), and is molded by injection molding or the like.

  First, the 1st fixing | fixed part 11 is demonstrated. As shown in FIG. 2, the first fixing portion 11 includes a substantially plate-like base 14. An elliptical extraction hole 16 is formed in the center of the pedestal 14 in the thickness direction. A cylindrical pouring portion 17 is formed on the upper surface of the base 14 so as to surround the pouring hole 16. The pouring portion 17 is formed in a shape such that the height of the back wall portion 17a is the highest, and the height decreases from the back wall portion 17a toward the front side.

  As shown in FIG. 3, a guide portion 15 is formed on the back side of the pedestal 14. The guide portion 15 extends vertically and downward with respect to the base 14. Further, the shape of the guide portion 15 in the width direction (Y direction in the drawing) is curved to the front side in accordance with the shape of the cup flange portion C1 in the circumferential direction. Furthermore, the lower end of the guide portion 15 is curved in an arc shape. Further, as shown in FIG. 4, a latching claw 15 a is formed at the center in the height direction (Z direction in the drawing) and the width direction in the front surface of the guide portion 15 so as to protrude to the front side. .

  Further, as shown in FIG. 4, a cylindrical perforated portion 18 surrounding the pouring hole 16 is formed on the lower surface of the base 14. The perforated part 18 is formed in a tapered shape whose tip is inclined downward from the front to the back. In addition, a pair of substantially elliptical communication holes 18 a are formed in the perforated portion 18 on the back side facing the guide portion 15.

  A flange portion 19 is formed on the bottom surface of the pedestal 14 and at the base end portion of the perforated portion 18. The flange portion 19 extends obliquely downward from the proximal end to the distal end. The front end of the flange portion 19 protrudes downward from the rear end, and the flange portion 19 is inclined to the front side when viewed from the side.

  Next, the 2nd fixing | fixed part 12 is demonstrated. As shown in FIG. 3, the 2nd fixing | fixed part 12 comprises plate shape, and the shape of the width direction (Y direction in a figure) curves toward the back side according to the shape of the circumferential direction of the cup collar part C1. doing. The length in the longitudinal direction is substantially the same as the length in the width direction of the guide portion 15.

  As shown in FIG. 4, a latching claw 12 a is formed at the center in the height direction and the width direction on the back surface of the second fixing portion 12. Furthermore, as shown in FIG. 5, an air hole forming portion 21 projects over the hooking claw 12 a in the back surface of the second fixing portion 12. On the lower surface of the air hole forming portion 21, a conical blade portion 22 is formed so as to protrude.

  Next, the connecting part 13 will be described. As shown in FIG. 2, the connecting portion 13 is composed of a pair of arcuate portions 13a that are bent inwardly. One end of the arcuate portion 13 a is fixed to both end portions on the front side of the first fixing portion 11, and the other end is fixed to both ends of the second fixing portion 12.

  In a state where no external force is applied, the arcuate portion 13a is disposed at the original position bent inward. At this time, as shown in FIG. 6, the length from the outer peripheral surface of the guide portion 15 to the outer peripheral surface of the second fixing portion 12 (hereinafter referred to as the total length L1) is larger than the diameter of the cup C including the cup flange portion C1. Is a length as small as several mm to several cm.

  Then, when the first fixing portion 11 is fixed and the second fixing portion 12 is pulled away from the first fixing portion 11, the bent arcuate portion 13a is expanded in the direction in which the amount of bending decreases. The As a result, the total length L1 of the spout S becomes longer and reaches the diameter of the cup C. At this time, since the arcuate portion 13a attempts to return to the original bent original position, the elastic force in the direction of approaching the first fixing portion 11 and the second fixing portion 12 by the restoring force of the arcuate portion 13a. Power is granted.

  Thus, since the spout S functions as an attachment independent of the cup C, not a container-integrated lid that covers the entire film F, the size can be reduced. For this reason, since the amount of resin used for spout S can be reduced, cost can be reduced.

  Next, the effect | action of the spout S of this embodiment is demonstrated according to FIGS. When the spout S is attached to the cup C, the longitudinal direction of the arcuate portion 13a of the spout S is made parallel to the film F as shown in FIG. Then, the spout S is lowered while the inner surface of the guide portion 15 is brought into contact with the outer surface of the cup collar C1. Then, the cup collar portion C1 is inserted into the gap between the guide portion 15 and the perforated portion 18.

  When the spout S is lowered, the tip of the perforated portion 18 pierces the film F, and the perforation of the film F is started. When the spout S is further lowered so as to approach the cup C, the perforated portion 18 is inserted deeper into the cup C, and the holes of the film F are enlarged toward the outside.

  In a state where the cup collar C1 is inserted only into the first fixing part 11, the arcuate part 13a is disposed at the original position bent inward as shown in FIG. 8, and the second fixing part 12 is the edge of the cup C. It is in a state not fixed to the part. Further, the total length L1 of the spout S is smaller than the diameter of the cup C including the cup collar C1.

  When the second fixing portion 12 is pulled toward the outer side in the cup radial direction from the state in which the cup collar portion C1 is inserted only in the first fixing portion 11, the arcuate portion 13a expands and bends as shown in FIG. The amount decreases. And if the 2nd fixing | fixed part 12 is pulled to the cup collar C1, the 2nd fixing | fixed part 12 will be hooked on the cup collar C1.

  As a result, the first fixing part 11 and the second fixing part 12 are fixed to the cup C as shown in FIG. In the mounting position where the spout S is fixed to the cup C, the fixing positions of the first fixing portion 11 and the second fixing portion 12 are opposed to each other through the cup opening. In other words, these fixed positions are positions that are symmetric with respect to the central axis X1 parallel to the height direction of the cup C. At this mounting position, the total length L1 of the spout S is substantially the same as the diameter of the cup C including the cup collar C1.

  Further, the connecting portion 13 is disposed at the extended position where the bending is reduced, and the elastic force in the direction toward the inner side in the cup radial direction with respect to the first fixing portion 11 and the second fixing portion 12 by the restoring force to return to the original position. Give. As a result, the first fixing portion 11 and the second fixing portion 12 apply a pressing force so as to sandwich the edge portion of the cup C from the outside, so that the spout S is firmly fixed to the cup C.

  Further, when the spout S is in the mounting position, the perforated portion 18 of the first fixing portion 11 is inserted deeper into the cup C, and a circular hole is formed in the film F. In addition, the flange portion 19 is pressed against the cup flange C1 to which the film F is fixed and the upper surface of the film F stretched on the cup opening, thereby ensuring a sealing property between the spout S and the film F. At this time, since the flange part 19 and the cup collar part C1 to which the film F is fixed are pressed against each other, a good sealing property can be secured. Further, since the flange portion 19 is inclined to the front side, the front end of the flange portion 19 is pressed against the film F on the inner side in the cup radial direction, which is relatively easy to bend. It is possible to prevent a gap from being generated.

  Further, the blade portion 22 of the second fixing portion 12 makes a hole in the film F. The hole formed at this time has a smaller opening area than the hole formed by the perforated part 18, and is provided at a position that is substantially symmetric with respect to the position of the hole formed by the perforated part 18 via the cup central axis. It has been.

  Thus, the spout S in the mounting position is restricted from moving in the cup radial direction, the height direction, and the circumferential direction of the spout S by the elastic force of the connecting portion 13. Furthermore, since the base 14 of the 1st fixing | fixed part 11 is arrange | positioned above the cup collar part C1 and the film F, the movement to a cup depth direction is also controlled. Further, when an external force that moves the spout S upward is applied, the hooking claws 12a, 15a and the cup collar C1 are hooked to restrict the movement. For this reason, the spout S is not easily tilted or displaced with respect to the cup C, and can maintain a stable posture.

  The spout S is mounted so as to pass through the central axis of the cup C and cross the cup opening. For this reason, the spout S can be fixed with respect to the center of gravity of the cup so that the weight is not biased to one side. Therefore, it is possible to prevent the cup C from falling easily by attaching the spout S, and the spout S is attached. The entire cup can be in a stable posture.

  When drinking the beverage in the cup on which the spout S is attached, the cup C is tilted toward the back wall portion 17a side of the pouring portion 17 as shown in FIG. Then, the beverage L in the cup is pushed out by the air flowing in from the air hole, flows into the perforated part 18 disposed below the film F, and is led out to the pouring part 17 through the pouring hole 16. Therefore, the drink L can be drunk by putting a mouth on the extraction part 17. At this time, as described above, since the spout S is not easily tilted or displaced, the beverage L can be easily drinkable.

  Further, when the cup C is tilted, the beverage L gathers in the vicinity of the spout, so that the water pressure increases in the vicinity of the spout, but the flange portion 19 is pressed against the cup collar C1 via the film F as described above. Thus, the sealing property is enhanced, and the beverage L can be prevented from leaking out between the spout S and the film F. In addition, since the beverage L interposed between the perforated part 18 and the inner surface of the cup can also be led out into the perforated part via the communication hole 18a of the perforated part 18, the beverage is drunk as little as possible in the cup. be able to.
