DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, embodiments of the invention will be described along examples with reference to the drawings.
1 to 4 are diagrams for explaining an embodiment of the synthetic resin cup container of the present invention. FIG. 1 is a perspective view, and FIG. 2 is a perspective view showing a state in which the flange body 11 is removed from the cup body 2. 3 is a perspective view in which the upper end portion is partially longitudinally cut and enlarged to show the main part, and FIG. 4 is a half vertical front view.
FIG. 4 shows a state in which the peripheral edge of the seal film 19 is bonded to the upper end surface of the flange 16 of the flange body 11 and the upper end opening of the flange body 11 is sealed with the seal film 19.

  The cup container 1 of the present embodiment is made of polypropylene (PP) resin, has a cylindrical side peripheral wall 3 that gradually decreases in diameter downward, and has a cup body 2 that is a member having a bottom portion 6 connected to the lower end portion. Two members of the flange body 11, which is a member made of low density polyethylene (LDPE) resin and having a flange 16 around the upper end of a cylindrical fitting cylinder piece 12 that gradually decreases in diameter downward. It is composed of

As shown in detail in FIG. 3, the upper end of the side peripheral wall 3 of the cup body 2 has a pair of peripheral protrusions 4 and 4a on the inner peripheral surface and the outer peripheral surface, and a little of the peripheral protrusions 4 and 4a. A pair of circumferential protrusions 5 and 5a are also provided below.
In addition, circumferential grooves 14 are respectively provided at height positions on the outer peripheral surface of the fitting cylinder piece 12 of the flange body 11 facing the peripheral protrusions 4 and 5 formed on the inner peripheral surface of the side peripheral wall 3 described above. And a circumferential groove 15 is disposed.
As shown in FIGS. 3 and 4, the flange body 11 is fitted into the upper end of the side peripheral wall 3 of the cup body 2 with the circumferential protrusions 4 and 5 fitted in the circumferential grooves 14 and 15. It is fixed with a set.
By fitting the circumferential protrusions 4 and 5 and the circumferential grooves 14 and 15, the flange body 11 is prevented from coming out of the cup body 2 due to the force acting on the flange 16 in the supply device or the like of the cup container 1. The locking function is demonstrated.

Here, the locking function using the fitting of the circumferential protrusions 4 and 5 and the circumferential grooves 14 and 15 is as follows.
The flange body 11 must be adjusted so gently that the flange body 11 can be easily attached and detached by hand.
The strength of such a locking function can be adjusted by the cross-sectional shape, the number of arrangement, or the arrangement position of the circumferential ridge or circumferential groove.

Of course, the locking function is not limited to the combination of the circumferential ridge and the circumferential groove as described above, and the direction in which the force is applied in the supply device and the direction in which the force is applied in attaching and detaching the flange body by hand. For example, various locking mechanisms such as combining a protrusion and a protrusion to form a crossing locking portion can be employed.
Incidentally, in the supply device or the like, a force that simply pulls the flange body 11 upward through the flange 16 acts, whereas in the operation of removing the flange body by hand, the flange body 11 is rotated or turned. However, since the force is applied, the locking function is configured in consideration of the difference in the action of the force, so that the pull-out resistance in the supply device or the like of the flange body 11 and the easy attachment / detachment of the flange body 11 during use can be reduced.

You can drink the contents smoothly without difficulty or discomfort.

  Further, on the outer peripheral surface of the side peripheral wall 3 of the cup body 2, a peripheral protrusion 4 a and a peripheral protrusion 5 a are disposed at positions facing the peripheral protrusion 4 and the peripheral protrusion 5 disposed on the inner peripheral surface, respectively. The circumferential ribs 4 and 4a and the circumferential ribs 5 and 5a exert a circumferential rib-like effect, and when used for drinking, when the flange body 11 is removed as shown in FIG. The deformation of the upper end opening of the cup body 2 can be suppressed, and the cup body 2 can be held in a stable posture.

Here, normally, in a cup container product filled with a liquid such as coffee, the peripheral portion of the sealing film 19 is adhered to the upper end surface of the flange 16 as shown in FIG. 11 is sold with the top opening sealed.
Even after the flange body 11 is removed and a part of the content liquid is drunk, the flange body 11 whose upper end opening is sealed with the seal film 19 is attached to the upper end of the cup body 2 again, so that the remaining content liquid is removed. The contained cup container 1 can be stored and transported with confidence.

  Next, FIG. 5 shows another example of the fitting mode between the cup body 2 and the flange body 11, and an example of fitting and assembling the cup body 2 and the flange body 11 by screwing. It is the perspective view which looked at the state where a part of upper end part of cup container 1 was cut longitudinally, and the principal part was expanded, and the point which formed the knurling which is one of the uneven pattern 18 in the composition concerning a fitting mode, and the side peripheral wall of flange 16 Other than this, the configuration is the same as that of the cup container shown in FIGS.

A screw 7 is disposed on the inner peripheral surface of the side peripheral wall 3 of the cup body 2. A pair of peripheral ridges 4, 4 a are provided at the upper end of the side peripheral wall 3 on the inner peripheral surface and the outer peripheral surface, and a peripheral ridge 5 a is provided at a position below the screw 7 on the outer peripheral surface.
Further, the flange body 11 is provided with a thread groove 17 that is screwed into the thread 7.
The flange body 11 can be firmly attached to the upper end portion of the cup body 2 so that it cannot be pulled out by screwing the screw 7 and the screw groove 17, and the firmly assembled flange body 11 can be screwed off. It can be easily removed by operation.
Further, a knurled which is an example of the uneven pattern 18 for preventing slipping is formed on the side peripheral surface of the flange 16 so that the above-described screwing and screwing operations can be easily performed.

As mentioned above, although embodiment of this invention and its effect were demonstrated along the Example, this invention is not limited to this Example.
