Description

[0001] The present invention relates to a straw cup having a straw insertion valve,

The present invention relates to a straw cup, in particular, it is possible to prevent the straw from easily falling out of the cup or from flowing in a severely inclined state, as well as to prevent the external leakage of the drink regardless of the presence or absence of the straw, The present invention relates to a straw cup which can be used without being greatly limited in thickness.

Many infants use straw cups with straws to prevent beverages from spilling or safety accidents when drinking beverages such as barley tea or milk. When the straw is integrated into the cup, it is virtually impossible to clean the inside of the straw every time, so there are many hygiene problems and almost all disposable straws are used.

When disposable straws are installed, it is necessary to fix the straws to a certain extent so as not to easily get out of the straw insertion holes. In order to prevent the disposable straw from easily falling out of the cup, a straw cup provided with a packing member in the straw insertion hole has been disclosed in Korean Patent Laid-Open Publication No. 2013-7800 (published on Jan. 21, 2013).

In the case of the Korean patent, since the packing member is made of a synthetic rubber material, the straw does not fall off from the straw insertion hole due to the adhesion between the straw and the packing member. In this case, it is important that the straw is inserted easily into the straw insertion hole so that the straw can not be easily released. However, the Korean patent does not consider this part at all.

The Korean patent does not prevent the tilting flow because there is no component for preventing the straw from tilting. If the tilting flow of the straw is free, there is an advantage in drinking the beverage, but if it is too free, it may be inconvenient to drink the beverage. In order to adjust the tilting of the straw and to fix the tilting, it is necessary to hold the straw by holding the straw and move or fix it. In order to manipulate it, the infant has to manipulate the tilting of the straw with one hand while holding the cup with one hand. In other words, you have to use both hands. Therefore, in the case of infants, it is more convenient to use the one hand so that the tilting flow of the straw is minimized and the cup is tilted or turned with the hand holding the cup.

In addition, when the straw is inserted, the Korean patent discloses that the beverage can be prevented from flowing out through the packing member, but when the straw is not present, the beverage leaks through the hole of the straw.

In addition, the straw cup disclosed in Korean Patent Publication has disadvantages in that it needs to have several straw insertion holes of different sizes in order to use straws of various thicknesses.

Accordingly, it is an object of the present invention to provide a drinking straw which can prevent the straw from easily falling out of the cup or from being severely tilted and can prevent the leakage of the beverage regardless of whether or not the straw is present, But also to provide a straw cup which can be used without being limited by the thickness of the straw even through the straw insertion hole.

According to an aspect of the present invention,

A cup body in which a beverage is received;

A lid installed to cover an inlet of the cup body; And

And a straw inserting valve which is fastened to the lid so that the straw passes through the lid and is inserted into the inside of the cup body,

Wherein the straw insertion valve includes a straw body through which a hollow passage is vertically installed,

The straw body is divided into an upper body to be fastened to the lid and a lower body to fasten the straw,

And the sidewall of the lower body is slid inward so that the straw inserted into the hollow is closely attached to the side wall of the hollow.

It is preferable that the side wall of the lower body has a concave shape. At this time, it is preferable that a vertical cutout groove is formed in a direction upward from the bottom of the side wall of the lower body.

The diaphragm may be provided in the hollow passage to block the hollow passage. In this case, the diaphragm preferably has a plurality of cutout grooves formed to cross the center of the diaphragm.
This is because the diaphragm is forcibly opened by the straw inserted into the hollow, so that the straw is doubly tightened not only by the sidewall of the lower body but also by the force of the diaphragm of the diaphragm, So as to further improve the sealability between the sealant and the sealant.

 The diaphragm is preferably installed at a boundary between the upper body and the lower body.

A lid pipe may be formed on the lid so as to penetrate through the lid, and a lid pipe may be formed on the bottom surface of the lid. At this time, the lid pipe is inserted and inserted into the hollow pipe, so that the straw body can be fastened to the lid.

And an annular stopping protrusion protrudes inwardly so that a foot of the lid pipe is hooked to a boundary portion between the upper body and the lower body.

Preferably, the diaphragm is installed in the hollow passage so as to cover the hollow passage while extending inwardly to the annular stopping jaw.

The straw body may be fastened to the lid by inserting and fitting the upper body into the lid tube. And an upper circular protrusion hooked to the opening of the lid hole and a lower circular protrusion hooked to the bottom of the lid tube are formed on the outer surface of the side wall of the upper body, respectively. And a step for receiving the upper circular protrusion is formed under the opening of the lid hole so that the upper body protrudes above the lid hole.

The straw body is preferably made of an elastic material such as silicone or synthetic rubber so that the diameter of the hollow tube is elastically expanded and restored.

According to the present invention, it is possible to prevent the straw from easily falling out of the cup or from flowing in a severely inclined state, and also to prevent the outer leakage of the beverage regardless of the presence or absence of the straw, So that it can be used without being greatly limited by the thickness of the film.

Therefore, the scope of the present invention should not be construed as being limited to these embodiments.

[Example 1]

1 is an external perspective view illustrating a straw cup according to a first embodiment of the present invention, and FIG. 2 is a sectional view of FIG. 1. 1 and 2, a straw cup according to the present invention comprises a cup body 10, a lid 20, and a straw insertion valve 100. The beverage is received in the cup body 10, and the lid 20 is installed so as to cover the inlet of the cup body 10. The straw insertion valve 100 is fastened to the lid 20 so that the straw 30 can pass through the lid 20 and be inserted into the cup body 10.

3 to 6 are views for explaining the straw insertion valve 100, which is a feature according to the first embodiment of the present invention.

3 to 6, the straw insertion valve 100 includes a straw body 110 through which the hollow passageway 120 is vertically penetrated. The straw body 110 is connected to the lid 20 And an upper body 112 and a lower body 114 for fixing the straw 30 to each other. Accordingly, the hollow passages 120 are divided into the upper hollow passages 122 in the upper body 112 and the lower hollow passages 124 in the lower body 114.

It is preferable that the side wall of the lower body 114 is formed to be inwardly curved as it goes down so that the straw 30 inserted into the lower hollow cavity 124 closely contacts the side wall of the lower hollow cavity 124, It is more preferable that the sidewall of the sidewall 114 is concave so as to closely adhere to the straw 30.

On the side wall of the lower body 114, a plurality of vertical incision grooves 117 are formed from the bottom to the top. This is to allow the straw 30 to slide downward as the sidewall of the lower body 114 is slightly opened when the straw 30 is inserted into the lower hollow 124.

A diaphragm 130 is installed in the hollow space 120 so as to cover the hollow 120. A plurality of cutout grooves 131 are formed in the diaphragm 130 so as to cross the center of the diaphragm 130. The diaphragm 130 is preferably installed at the interface between the upper hollow space 122 and the lower hollow space 124.

And an annular stopping protrusion 115 protrudes inward from a boundary between the upper hollow space 122 and the lower hollow space 124. At this time, it is preferable that the diaphragm 130 is installed so as to extend inward from the annular stopping jaw 115.

The lid 20 is formed to penetrate through the lid hole and the lid pipe 25 is formed on the bottom surface of the lid 20 so as to extend downward while making the lid hole as an opening. The lid pipe (25) is inserted into the upper hollow space (122) so as to be inserted into the lid (20), and the straw body (110) is fastened to the lid (20).

Since the straw body 110 is fitted in a tight fitting manner when it is fitted into the lid tube 25 and the side wall of the lower body 114 will be in close contact with the straw 30 with a certain tightening force, 110 are preferably made of an elastic material. Examples of such an elastic material include silicon or synthetic rubber. As the hot beverage is often contained in the cup, it should be resistant to heat and harmful substances should not dissolve, and it is also preferable that it is hygienically excellent.

Hereinafter, the principle of use of the straw cup according to the present invention will be described.

[When you put the straw (30)]

As shown in FIG. 5B, the straw 30 is inserted into the cup body 10 through the lower hollow passage 124 while piercing the middle portion of the diaphragm 130. Since the diaphragm 130 is normally closed but a plurality of cutting grooves 131 are formed, when the downward pushing force is applied by the straw 30, the middle portion of the diaphragm 130 is worn down and sideways.

Since the sidewall of the lower body 114 has a smaller diameter than the straw 30, the straw 30 is closely adhered to the sidewall of the lower body 114 at this portion. Therefore, even when the straw 30 is inserted, the beverage is prevented from leaking to the outside through the gap where the straw 30 is inserted.
Particularly, since the diaphragm 130 is forcibly opened by the straw 30 inserted into the hollow passages 120, the straw 30 is prevented from being twisted by the force of the sidewall of the diaphragm 130, So that the sealing performance of the straw 30 in the lower hollow passage 124 is very excellent, and such external leakage is almost completely blocked.

 Since the movement of the upper and lower portions of the straw 30 is restrained by the lid pipe 25 and the lower body 114, the tilting movement of the straw 30 is limited.

 [When removing the straw (30)]

As shown in FIG. 5A, when the straw 30 is moved upward, the side wall of the lower body 114 tries to catch up with the straw 30 because of the close contact with the straw 30. However, the sidewalls of the lower body 114 are not formed in a free-flowing shape, so they are not rolled up. Accordingly, the straw 30 is not easily pulled up due to adhesion with the lower body 114. That is, although the straw 30 can be easily inserted, it does not easily fall out.

When the straw 30 is completely lifted up, the diaphragm 130 which has been opened is closed by the elastic restoring force. Therefore, the beverage does not leak to the outside even when the straw 30 is not inserted.

FIG. 7 is a sectional view for explaining a straw cup according to a second embodiment of the present invention, and FIGS. 8 and 9 are views for explaining a straw insertion valve 100, which is a feature according to a second embodiment of the present invention .

7 to 9, the second embodiment differs from the first embodiment in that the upper body 112 is inserted into the lid pipe 25 so as to be inserted into the lid 20 so that the straw body 110 is fastened to the lid 20 . Due to this difference, the upper circular protuberance 141 and the lower circular protuberance 142 protrude from the outer surface of the side wall of the upper body 112, respectively.

The upper circular protuberance 141 is caught by the opening of the lid hole and the lower circular protuberance 142 is caught by the bottom of the lid pipe 25 so that the straw body 110 is firmly fastened to the lid 20. A step portion 125 for receiving the upper circular protuberance 141 is formed below the opening of the lid hole so that the upper body 112 does not protrude above the lid hole.

As described above, according to the present invention, it is possible to prevent the straw 30 from easily falling out of the cup or from being severely tilted, and it is also possible to prevent the external leakage of the beverage regardless of whether or not the straw 30 is present .

According to the present invention, since the straw 30 is caught by the diaphragm 130 and the lower hollow passages 124, straws 30 of various thicknesses can be used even if only one straw insertion valve 100 is installed.
