Description

The present invention relates to a cup that does not require a straw.

In the past, straws were generally made of plastic because they are resistant to water and durable, but in recent years, the number of disposable plastic products, including straws, has been decreasing due to problems such as environmental pollution.

Therefore, in recent years, there is a fact that paper straws have been used in cafes and the like.

Japanese Utility Model Laid-Open No. 62-73767

The idea disclosed in Patent Document 1 is a "paper cup with a straw", specifically, "a straw is inserted and adhered along the inner wall of the paper cup from near the opening of the paper cup to near the bottom, and the paper cup is attached. A paper cup with a straw that is made by bending the mouthpiece of a straw along the inner edge of the opening of the paper cup through the folded part of the straw near the opening, and bonding the part so lightly that it can be peeled off with a finger. be.

However, the straw according to Patent Document 1 has a bent portion having a bellows-like flexible structure, although the material is not described, and is made of plastic.

Also, the straw and the paper cup are glued inside the paper cup with an adhesive, and even if the adhesive is harmless to the human body, it is not good for food hygiene if the adhesive is exposed where the beverage comes into contact. I don't like it.

Also, a person who drinks drinking water may drink the finely divided adhesive.

An object of the present invention is to provide a cup that does not require a straw.

Another object of the present invention is to provide a cup that produces less waste.

A cup according to the first aspect of the present invention is a cup that can be filled with a beverage,
a cup body capable of storing beverages;
a straw part through which a beverage can be sucked; and
The cup main body includes a main body side portion forming a side surface of the cup;
and a main body bottom portion forming the bottom surface of the cup,
The main body side portion has a left end portion and a right end portion,
The straw portion is a cup formed by overlapping and connecting the left end portion and the right end portion of the main body side portion with a space through which the beverage can pass.

Since the cup is provided with a straw part, waste can be reduced.

Moreover, a paper material can also be used for such a cup.

In addition, since the straw portion is formed by overlapping the left end portion and the right end portion of the main body side portion, waste can be reduced when the cup is manufactured when the paper material is used.

A cup according to a second aspect of the present invention is the cup according to the first aspect,
The straw part has an outer straw part and an inner straw part formed by the main body side part,
A space through which the beverage passes is provided by connecting the outer straw portion and the inner straw portion,
The cup has a gap through which the beverage passes between the inner straw part and the bottom surface of the main body.

The beverage in the cup passes through the gap provided between the inner straw portion and the bottom surface of the main body, and passes through the space formed by the outer straw portion and the inner straw portion.

With such a configuration, when a paper material is used, waste can be reduced in manufacturing the cup.

A cup according to a third aspect of the present invention is the cup according to the first aspect or the second aspect,
In the cup, the upper end portion of the straw portion is inclined radially outward in plan view.

With such a configuration, the user of the cup can easily put the upper end of the straw to the mouth and drink the beverage in the cup.

A cup according to a fourth aspect of the present invention is the cup according to the first aspect, the second aspect, or the third aspect,
In the cup, the straw portion extends upward from the upper end of the cup body portion.

The elongated straw makes it easier for the user of the cup to drink the beverage.

A cup according to a fifth aspect of the present invention is the cup according to the first to fourth aspects,
In the cup, the upper end of the straw portion is shaped like a mountain.

Since the upper end of the straw portion is shaped like a mountain, the user of the cup can easily put his or her mouth on the cup and drink the beverage in the cup easily.

The second outer straw part 510 is composed of parts arranged outside the overlapped parts of the main body side part 210 .

The second outer straw portion 510 has a configuration in which a portion of the main body side portion 210 extends upward (toward the positive direction of the z-axis).

The second inner straw portion 520 is composed of a portion disposed inside the overlapped portion of the main body side portion 210 .

As with the second outer straw portion 510, the second inner straw portion 520 also has a configuration in which a portion of the main body side portion 210 extends upward (toward the positive z-axis direction).

In other words, the second straw portion 500 is configured to extend upward (toward the positive direction of the z-axis) from the cup body upper end 201 of the cup body portion 200 .

As shown in FIGS. 11 and 12, the second outer straw part 510 and the second inner straw part 520 are connected to form a space through which the beverage passes, so that the user can easily suck the beverage. ing.

Specifically, the central portion of the second outer straw portion 510 in plan view bulges outward in the radial direction (negative direction of the y-axis) in plan view, and the central portion of the second inner straw portion 520 in plan view bulges. There is a bulge radially inward (y-axis positive direction side), and a space through which the beverage passes is provided by the second outer straw portion 510 and the second inner straw portion 520 .

In this embodiment, the second outer straw portion 510 does not bulge radially outward (y-axis negative direction side) in plan view at the end portion (z-axis negative direction side) of the second outer lower end portion 512, and the main body bottom surface It has a configuration that facilitates connection with the unit 220 .

The second outer upper end portion 511 is arranged on the upper end side of the second outer straw portion 510 .

As shown in FIGS. 7 to 12, the second outer upper end portion 511 has a mountain-like shape on the xz plane.

The shape of the second inner upper end portion 521 is, like the second outer upper end portion 511, a mountain-like shape on the xz plane.

The upward extension of the second straw portion 500 makes it easier for the user of the first cup 100 to drink the beverage.

Note that the second outer upper end portion 511 and the second inner upper end portion 521 may be inclined radially outward (y-axis negative direction side) in a plan view like the first embodiment.

The second outer lower end portion 512 is arranged on the lower end side of the second outer straw portion 510 .

The second inner lower end portion 522 is arranged at the lower end portion of the second inner straw portion 510 .

The second inner lower end portion 522 has a gap G between the end portion of the second inner lower end portion 522 and the bottom surface portion 221 .

The beverage in the second cup 400 passes through the gap G and over the space formed by the second outer straw portion 510 and the second inner straw portion 520 .

Since the second straw portion 500 is configured in the second cup 400, the user of the second cup 400 can drink the beverage without using a separate straw and can tilt the second cup 400. can drink without

<Third Embodiment>
The third embodiment has the same configuration as the first embodiment, but as can be seen from FIGS. ) is thin (the width in the y-axis direction is narrow).

In the third embodiment, descriptions of the same configurations as those according to the first and second embodiments are omitted.

The third cup 600 according to the third embodiment will be described using the same reference numerals as the first cup 100 according to the first embodiment.

The third cup 600 according to the third embodiment has a configuration in which the first outer mold upper end portion 311 and the first inner upper end portion 321 of the first straw portion 300 are inclined radially outward (y-axis negative direction side) in plan view. It is configured such that it extends upward (toward the positive direction of the z-axis).

Even the configuration according to the third embodiment has the same effect as the configuration according to the first embodiment.
