Abstract

A drink container includes a container 1, a lid 3 joined to an upper opening of the container, and a drip prevention element 2; the lid has a sucking portion 31 for allowing a person to suck on to draw out drink contents of the container with the mouth; the lid is formed with a passage 35 for allowing drink contents of the container to pass through; the drip prevention element 2 is arranged in the passage of the lid to block the passage when there is no external sucking force exerted on the sucking portion, and which can bend to effect opening of the passage when there is external sucking force exerted on the sucking portion; thus, liquid contents can't drip through the lid in case the drink container falls over. The valve member 21 is arranged at an angle to the lid passage so that suction causes it to bend away therefrom allowing flow therethrough. When the suction is released, the valve member returns and low pressure in the container causes the valve member to bend the other way allowing fluid to return to the container.

STRUCTURE OF A DRINK CONTAINER

BACKGROUND OF THE INVENTION

s 1. Field of the invention

The present invention relates to a drink container, more particularly one, which is structured so that liquid contents thereof can't drip when it is laid down or inverted.

2. Brief Description of the Prior Art

There are drink containers especially designed for small children and capable of being used for training small children to grasp objects.

Because small children still can't hold a cup firmly for an extended period of time, such drink containers for small children are usually made of breakage-resistant materials so that they won't break if they fall down onto the ground.

Referring to Figs. 6, and 7, European Patent No. EP0635922B1 discloses a learner drinking vessel, which includes a container 4, and a lid 41 joined to the upper end of the container 4. The lid 41 has a spout 411 in fluid communication with the container 4. A valve member 42 is disposed under the lid 41, and has a drip-prevention aperture 421 formed thereon to be in communication with the spout 411. When a person sucks on the spout 411, liquid contents of the vessel are forced to flow through the drip-prevention aperture 421 into his/her mouths. When small children play with the learning drinking vessel, and hold the same in various positions, e.g. an inverted one, liquid contents of the vessel can't drip through the drip-prevention aperture 421. Furthermore, the drinking vessel is made of breakage-resistant materials, e.g. PP, so that it can't s break if it falls down or hits other objects. Therefore, the drinking vessel is safe to use, and has relatively long service life, having relatively few disadvantages. However, this type of learner drinking vessel has been made available in the market for many years, and there are not many different drinking vessels provided as other options. to

SUMMARY

It is a main object of the present invention to provide a drink container, which is structured so that liquid contents thereof can't drip when it is laid down or inverted.

The drink container includes a containing body for containing drinks therein, a lid joined to an upper opening of the containing body, and a drip prevention element. The lid has a sucking portion for allowing a user to suck on to draw out drink contents of the containing body with the mouth. The lid is formed with a passage for allowing drink contents of the containing body to pass through. The drip prevention element has a valve portion, which is arranged in a passage of the lid to sealingly contact an inner side of the lid to block the passage when there is no external sucking force exerted on the sucking portion, and which can bend to effect opening of the passage when there is external sucking force exerted on the sucking portion.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to Fig. 1, a preferred embodiment of a drink container in the present invention includes a containing body 1, a drip prevention element 2, and a lid 3. The containing body 1 is make of breakage-resistant materials, and is provided for containing drinks. The lid 3 is joined to the upper end of the containing body 1. The lid 3 s includes a sucking portion 31, and a connecting portion 34 projecting from a lower side of the sucking portion 31. There are a central through hole 32, and several outlets 33 formed on the sucking portion 31. There is a central hole 35 formed in the connecting portion 34, and communicating with the central through hole 32 and the outlets 33 of the lid 3.

The drip prevention element 2 is made of silicon rubber or other rubber materials so that it has flexibility and original shape thereof can be restored when external force exerted on it disappears. The drip prevention element 2 includes a sloping valve portion 21, and a post portion 22, which sticks up from an upper side of the valve portion 21 so that the drip prevention element 2 is substantially shaped like a "T".

There are two separate annular protrusions 221 formed on the post portion 22, and there is an annular recess 222 formed between the annular protrusions 221. The diameter of the valve portion 21 is slightly bigger than that of the central hole 35 of the connecting portion 34 of the lid 3 so that the valve portion 21 can fit sealingly in the lid 3.

In assembly, the drip prevention element 2 is inserted into the central hole 35 of the connecting portion 34 of the lid 3, and the post s portion 22 is passed through the central through hole 32 of the sucking portion 31 of the lid 3 with the annular protrusions 221 being arranged on two sides of the sucking portions 31, i.e. the annular recess 222 of the post portion 22 is fitted in the central through hole 32. Then, the lid 3 is s joined to an upper opening of the containing body 1 at the connecting portion 34. Furthermore, the valve portion 21 is formed such that a line normal to it can be parallel to a central axis of the central hole 35 of the connecting portion 34 of the lid 3 or not.

Referring to Fig. 2, drinks are contained in the containing body 1.

When a person sucks on the sucking portion 31 of the lid 3 with the lip covering the holes 32, and 33, a negative pressure will be formed in the sucking portion 31, causing an edge of the valve portion 21 to bend towards the sucking portion 31, as shown in Figs. 3, and 4. Thus, a space comes into existence between the valve portion 21 and the connecting portion 34 of the lid 3, and liquid contents of the containing body l can flow into his/her mouth via the through holes 32, 34, and the outlets 33 of the lid 3.

Relatively low pressure will be caused in the containing body 1 by the sucking force. When the user stops sucking on the sucking portion 31, liquid between both the valve portion 21 and the connecting portion 34 will be forced to move back into the containing body 1 due to the relatively low pressure in the containing body 1, and the valve portion 21 will move back to the original shape to sealingly contact the inner side of the containing portion 34 of the lid 3, as shown in Fig. 2. Thus, liquid contents of the containing body 1 won't drip through the lid 3 when the present drink container falls over. And, in case small children play with the present drink container for learning to grasp objects, and move the same to various positions such as an inverted one and a laid- down one, liquid contents of the containing body 1 can't drip through the lid 3.

From the above description, it can be understood that the drink container of the present invention can be used as ordinary drinking vessel as well as a kit for young children to learn to grasp objects with.

And, the drip prevention element 2 will prevent drink contents of the containing body 1 from dripping out through the lid 3 when the drink container falls over. And, liquid will not be left above the valve portion 21 to flow out because when the user stops sucking on the sucking portion 31, liquid between both the valve portion 21 and the connecting portion 34 will be forced to move back into the containing body 1 by the relatively low pressure in the containing body 1.
