However, in the conventional cup container, the sealing material is peeled off from the upper surface of the cup flange portion while the cup body is being pressed in the radial direction of the cup, so that when the upper end opening of the cup body is opened, the cup body is additionally added. There was a risk that the liquid content would be pushed into and deformed, and the content liquid would overflow from the cup body.

The present invention has been made in consideration of such circumstances, and suppresses the content liquid from scattering when the sealing material is peeled from the upper surface of the cup flange portion to open the upper end opening of the cup body. The object is to provide a cup holder capable of

In order to solve the above problems and achieve such an object, the cup holder of the present invention has a cup body in which a content liquid is stored, and a cup body protruding from the upper end portion toward the outer side in the radial direction of the cup.

The upper surface of the lower wall 23 is substantially parallel to the upper surface of the bottom wall 15.

The upper wall 22 covers, from above, a portion of the upper surface of the lower wall 23 that protrudes radially outward from the upper end opening edge of the half-split cylinder portion 17. Similar to the lower wall 23, the upper wall 22 is formed in a plate shape having a length in the circumferential direction and a width in the radial direction, and has a C-shape that is open toward the front when viewed from above and below. So curved. The inner peripheral edge of the upper wall 22 is formed in an arc shape centered on the central axis O. The radial positions of the inner peripheral edge of the upper wall 22 and the inner peripheral surface of the upper end portion of the half-split cylinder portion 17 are equal to each other. The shapes of the upper wall 22 and the lower wall 23 in a top view are symmetrical with respect to a straight line passing through the central axis O and the rear end edge of the peripheral wall 14. The lower surface of the upper wall 22 is substantially parallel to the upper surface of the bottom wall 15.
Radial outer ends of the upper wall 22 and the lower wall 23 are connected to each other by a connecting wall 24.

The locking part 13 is separated from the upper surface of the cup flange part W2 and locks the front end part of the sealing material W3 folded back.
The locking portion 13 is arranged with a vertical gap provided between the locking portion 13 and the upper surface of the upper wall 22. The lower surface of the locking portion 13 is substantially parallel to the upper surface of the bottom wall 15. The locking portion 13 extends in the left-right direction, which is orthogonal to both the front-rear direction and the vertical direction. One end portion of both end portions in the left-right direction of the locking portion 13 is arranged above the center portion in the circumferential direction on the upper surface of the upper wall 22. The locking portion 13 and the upper surface of the upper wall 22 are connected via a connecting portion 25. The connecting portion 25 is arranged on the upper surface of the upper wall 22 at a position away from the central portion in the circumferential direction. The connecting portion 25 is connected to the other end of the locking portion 13 in the left-right direction, which is on the other side of the upper wall 22 away from the central portion in the circumferential direction.

In the above configuration, with the cup body W1 inserted inside the peripheral wall 14 of the surrounding cylinder 11 and the cup flange portion W2 inserted in the insertion portion 12, the lower surface of the upper wall 22 is the cup flange portion. By contacting the upper surface of W2 and the upper surface of the bottom wall 15 with the bottom portion of the cup body W1, the cup container W is extended so as to extend rearward as the central axis of the cup body W1 goes upward. , Is held in a state of being inclined with respect to the ground plane direction along the ground section 16.

At this time, the top view shape of the cup container W is symmetrical with respect to a straight line passing through the central axis O and the rear end edge of the peripheral wall 14, and the projecting portion of the cup flange portion W2 is located in front of the cup holder 1. doing. In the illustrated example, the inner peripheral surface of the half-cylindrical portion 17 is in contact with the outer peripheral surface of the cup body W1.

As described above, according to the cup holder 1 according to the present embodiment, the surrounding cylinder 11 and the insertion portion 12 hold the cup container W in a state of being inclined with respect to the ground contact surface direction along the ground contact portion 16. By doing so, the central axis of the cup body W1 in the state of being attached to the cup holder 1 is extended backward as it goes upward, so that the cup container W is held and grounded as shown in FIG. With the portion 16 grounded to the grounding surface L (hereinafter, referred to as a set state), the front end of the liquid surface of the content liquid A stored in the cup body W1 is moved downward from the front end of the upper end opening of the cup body W1. It is possible to separate and move the content liquid A attached to the front end portion of the inner peripheral surface of the cup body W1 and the front end portion of the lower surface of the sealing material W3 to the rear.

Therefore, in the set state, the content liquid A can be separated from the front end portion of the upper end opening of the cup body W1, and the front end portion of the sealing material W3 is pulled up from the cup body W1 to open the upper end opening of the cup body W1. When doing so, it is possible to prevent the content liquid A in the cup body W1 from jumping out from the front end portion of the upper end opening of the cup body W1.

In the set state, the cup main body W1 is surrounded by the peripheral wall 14 of the surrounding cylinder 11. Therefore, when peeling the sealing material W3 from the upper surface of the cup flange portion W2, it is possible to grasp the surrounding cylinder 11 instead of the cup main body W1. It will be possible. Therefore, when the sealing material W3 is peeled from the upper surface of the cup flange portion W2 and the upper end opening of the cup body W1 is opened, the rigidity of the cup body W1 is reduced, and thus the cup body W1 is pushed in the cup radial direction. It is possible to prevent the contents liquid A from overflowing from the cup body W1.

Since the peripheral wall 14 of the surrounding cylinder 11 has a C-shape that is open toward the front when viewed from above and below, and the insertion port 21 of the insertion portion 12 is open toward the front, it is a cup container. By moving W relatively backward with respect to the cup holder 1, it becomes possible to insert the cup body W2 into the surrounding cylinder 11 and insert the cup flange portion W2 into the insertion portion 12, thereby making the cup container W Can be easily set in the cup holder 1.

The lower surface of the upper wall 22 abuts on the upper surface of the cup flange portion W2, and the upper surface of the bottom wall 15 of the surrounding cylinder 11 abuts on the bottom portion of the cup body W1, thereby tilting the cup container W as described above. Since the cup container W is held in this state, the entire cup container W is vertically sandwiched and held, and the attitude and position of the cup container W with respect to the cup holder 1 can be stabilized.

The upper surface of the bottom wall 15 of the envelope 11 extends downward as it goes rearward, and the bottom of the cup body W1 contacts the inclined upper surface in this manner. The contact area between the upper surface and the bottom of the cup body W1 can be secured, and the attitude and position of the cup container W with respect to the cup holder 1 can be reliably stabilized.

Since the extruding hole 19 that penetrates in the front-rear direction and allows a finger to be inserted is formed in the peripheral wall 14 of the surrounding cylinder 11, the finger is inserted into the extruding hole 19 after the content liquid A in the cup body W1 is poured out. It is possible to push the cup body W1 forward with a finger to push out the cup container W from the cup holder 1. Therefore, the cup container W can be detached from the cup holder 1 without touching the cup flange portion W2 and the seal material W3, and the content liquid A can be prevented from adhering to the hand at the time of this detachment.

Since the seal member W3 peeled from the upper surface of the cup flange portion W2 and folded back is provided with the locking portion 13 capable of locking the front end portion, the seal folded back after opening the upper end opening of the cup body W1. The front end portion of the material W3 can be locked to the locking portion 13, and it is possible to prevent the sealing material W3 from being restored and deformed and becoming an obstacle when the content liquid A is poured.

In the configuration, the cup container W is held in a state of being inclined with respect to the ground contact surface direction along the ground contact portion 16 so that the central axis of the cup body W1 in FIG. Only one of the surrounding cylinder 11 and the insertion part 12 may hold the cup container W in the inclined state as described above.
For example, the upper wall 22 and the lower wall 23 may contact the upper and lower surfaces of the cup flange portion W2 to hold the cup container W in an inclined state as described above.

As the peripheral wall 14, a configuration including a pair of curved portions that individually extend forward from the front end opening edge of the half-split cylinder portion 17 may be adopted. When viewed in the vertical direction, the radii of curvature of the curved portion and the radius of curvature of the half-split cylinder portion 17 may be equal to each other.
Although the configuration having the locking portion 13 is shown, the locking portion 13 may not be provided.
The locking portion 13 may be arranged, for example, on the outer peripheral surface of the peripheral wall 14.

Although the upper surface of the bottom wall 15 is inclined with respect to the ground plane direction along the ground portion 16 so as to extend downward as it goes rearward, the upper surface of the bottom wall 15 is in the same vertical position over the entire area. Is located at the upper side of the bottom wall 15 of the surrounding cylinder 11, and a protruding rib whose protruding height becomes lower toward the rear is formed, and the bottom of the cup body W1 is brought into contact with the protruding rib.
