  Embodiments of the present invention will be described below with reference to the drawings. In the illustrated embodiment, a lid body 6 having a cutting blade wall plate 13 for cutting and opening the sealing member 23 is tightly assembled in a cover shape on the container body 1 whose upper end opening is sealed with the sealing member 23. It has been.

  The container body 1 has a bottomed cylindrical shape in which the lower end of the body portion 2 slightly reduced in diameter is closed with a bottom portion 4, and a mouthpiece 5 is provided around the periphery of the upper end opening. The sealing member 23 on the upper surface of 5 is tightly adhered to achieve sealing of the container body 1. The protrusion 3 projecting from the lower end portion of the inner peripheral surface of the body portion 2 is used for preventing the stacking of the container body 1, and the body portion 2 is extended downward at the lower peripheral edge of the bottom portion 4. The leg pieces are shaped.

  The lid body 6 is composed of a cylindrical peripheral wall 7 and a partition-like body wall 10 that divides the interior of the peripheral wall 7 in the vertical direction. The mounting function part is formed by the mounting cylinder piece 8 to be stopped and the abutting cylinder piece 9 that abuts against the seal member 23 portion affixed to the upper surface of the mustache 5 from above.

  The main body wall 10 is divided into a base wall plate 11 and a cutting blade wall plate 13 by a hinge 19 and a slit 20, and the cutting blade wall plate 13 is composed of a tip blade portion 14 and a plate piece portion 16. Further, by connecting the base end of the plate piece portion 16 to the base wall plate 11 by the hinge 19, the plate piece portion 16 can swing up and down with the hinge 19 as a fulcrum. The distal end portion in the posture is defined as a distal end blade portion 14, and the blade that is the lower end edge of the distal end blade portion 14 is directly above the peripheral end edge of the seal member 23 portion that seals the upper end opening of the container body 1. , Located along the peripheral edge.

  Further, the main body wall 10 is provided with a cutting edge cylinder piece 21 having a lower end edge as a cutting blade capable of cutting the seal member 23 so as to be vertically displaceable, separately from the cutting edge wall plate 13, An opening is opened in the seal member 23.

  Since the cutting-blade cylinder piece 21 has a cylindrical shape, even if the cutting-blade cylinder piece 21 still enters the opening that is opened by cutting the sealing member 23, the cutting-blade cylinder 21 The piece 21 never blocks the opening, and the open state is always ensured.

In the case of the cup container with a lid shown in FIGS. 1 to 4, the cutting blade wall plate 13 is formed in a plate shape that rises and widens on the tip side, and is an upper surface of the plate piece portion 16 that is raised and positioned at the upper level. The tip portion is formed with a fine anti-slip ridge that forms a depressed portion by the fingertip (see FIG. 2), and the tip blade portion 14 is curved and descends from the tip of the plate piece portion 16. It is formed into a wide hanging plate piece (see FIG. 1). The rib piece 15 provided on the lower surface of the cutting blade wall plate 13 reinforces the raised structure of the cutting blade wall plate 13.

  Therefore, compared to the distance from the hinge 19 to the tip of the plate piece portion 16, the distance from the hinge 19 to the blade of the tip blade portion 14 is increased (see FIG. 1), and this causes a small depression on the plate piece portion 16. By the stroke, a large downward swinging stroke of the tip blade portion 14 can be obtained, thereby enabling a large opening to be opened in the seal member 23 by an ordinary pressing without excessive force on the cutting blade wall plate 13. Become.

  In the substantially central portion of the plate piece portion 16, the cutting blade cylinder piece 21 is provided in a hanging shape with its lower end edge positioned directly above the seal member 23 (see FIG. 1). At the same time that the wall plate 13 is pushed down and an opening is opened in the seal member 23 by the leading edge 14, an opening by the cutting blade cylinder piece 21 is opened in the seal member 23 (see FIG. 3).

  Further, the base wall plate 11 has a pedestal piece 12 (see FIG. 1) having a height larger than the rising degree of the cutting blade wall plate 13 in a substantially three-quarter arc shape (see FIG. 2) along the peripheral wall 7. ) So that other cup containers with lids can be safely stacked without the cover 24 (see FIG. 4).

In the case of the embodiment of the present invention shown in FIGS. 5 to 7, the cutting blade wall plate 13 includes a plate piece portion 16 (see FIG. 6) having a wide flat plate shape, and a plate piece positioned along the peripheral wall 7. It is composed of a distal edge 14 (see FIG. 5) bent down from the distal edge of the portion 16 (see FIG. 6), and from both sides of the proximal edge of the plate piece 16 hinged to the base wall plate 11 A lifting piece 17 whose extending end is raised obliquely upward is extended (see FIG. 6), and a locking piece for holding the cutting blade wall plate 13 in a swinging displacement state on the upper surface of the lifting piece 17. 18 is erected.

  Therefore, when the extended end of the lifting piece 17 is pulled up by the fingertip, the cutting blade wall plate 13 is swung up and down with the hinge 19 as a fulcrum, and the tip blade 14 is swung down and displaced immediately below. The sealing member 23 is cut to form an opening.

  When the oscillating displacement of the cutting blade wall plate 13 is pushed forward and reaches the oscillating displacement limit position (see FIG. 7) where the lifting piece 17 abuts against the peripheral wall 7, the locking piece 18 is engaged with the peripheral wall 7 (see FIG. 7). Thus, the swinging displacement posture of the cutting blade wall plate 13 is maintained, whereby the opening state of the opening is stably maintained in an appropriate state.

  A cutting blade cylinder piece 21 hangs on the base wall plate 11 via a spiral spring piece 22 (see FIG. 6) in a state where the lower end edge is positioned directly above the seal member 23 (see FIG. 5). In addition to the opening operation by the cutting blade wall plate 13, the opening of the opening by the cutting blade cylinder piece 21 (see FIG. 7) is achieved by pressing the fingertip against the cutting blade cylinder piece 21. .

Next, an example of handling the illustrated cup container with a lid will be described. In the case of the cup container with a lid shown in FIGS. 1 to 4, when the top end portion of the plate piece portion 16 of the cutting blade wall plate 13 is pushed down with a fingertip, the leading end blade portion 14 and the cutting blade cylinder piece 21 swing down. Displacement is performed, and an opening is opened in each sealing member 23.

  When the opening opening formed by the tip blade portion 14 is made to function as an outlet for the contents liquid, the contents liquid is poured out by inclining the entire cup container with a lid. At this time, the opening opening by the cutting blade cylinder piece 21 is Functions as replacement air. Further, when the content liquid is sucked out by the straw 25 using the opening formed by the cutting blade cylinder piece 21, the straw 25 is inserted from the cutting blade cylinder piece 21, and the straw 25 is supported by the cutting blade cylinder piece 21. Thus, the content liquid can be sucked out stably. At this time, the opening opening by the tip blade portion 14 functions as replacement air.

In the case of the embodiment of the present invention shown in FIGS. 5 to 7, when the lifting piece 17 is pulled up with the fingertip, the tip blade portion 14 swings down and displaces, and an opening is opened in the seal member 23. Separately, the cutting blade cylinder piece 21 is pushed down against the elasticity of the spring piece 22 to open an opening in the seal member 23.

  When the opening opening formed by the tip blade portion 14 is made to function as an outlet for the content liquid, the content liquid is poured out by inclining the entire cup container with the lid. If formed, the opening functions as a replacement air, so that a smooth content liquid pouring operation can be obtained. Further, when the content liquid is sucked out by the straw 25 using the opening formed by the cutting blade cylinder piece 21, the straw 25 is inserted from the cutting blade cylinder piece 21, and the straw 25 is supported by the cutting blade cylinder piece 21. In this case, if the opening is formed by the tip blade portion 14, the opening functions as a replacement air, so that the liquid can be sucked out smoothly. You can get action.

  The embodiment of the present invention is not limited to the illustrated form. For example, the container body 1 can be a bottomed rectangular tube instead of a bottomed cylindrical shape. The same applies to the body 6.

  As explained above, the cup container with a lid of the present invention has a cutting blade wall plate and a cutting blade cylinder piece that opens the opening in the sealing member, so that the opening forming form suitable for the use state can be freely set. A wide range of usage can be expected especially as a portable cup container with a lid.
