- According to this configuration, since the valve means enables the air supply port in the cap body to be opened and closed according to the sucking operation of the tube, for example, by mounting the cap body on the mouth portion of the vessel, a liquid in the vessel can be drunk by sucking the tip end of the tube. Further, when the interior of the vessel becomes at a negative pressure according to the sucking operation of the tube, the valve means is opened to supply the outside air into the vessel, so that the liquid in the vessel can be drunk smoothly.
- To attain the above object, the present invention provides a replacement cap for a vessel, in which a cap body is mounted on a mouth portion of the vessel so as to be replaceable so that a liquid in the vessel can be drunk through a tube provided on the cap body, wherein the cap body is provided with an air supply port having cup-shaped valve means which is closed normally and is opened to supply the outside air into the vessel when the interior of the vessel becomes at a negative pressure.
- According to this configuration, not only the liquid in the vessel can be drunk by sucking the tip end of the tube but also the liquid in the vessel can be drunk smoothly because the valve means is opened to supply the outside air into the vessel when the interior of the vessel becomes at a negative pressure.
- Also, since the air supply port is normally closed by the valve means, even if the vessel is laid down or turned down mistakenly, the liquid in the vessel does not leak from the suction port, so that there is no fear that the leaking liquid soils clothes etc.
- To attain the above object, in the replacement cap for a vessel in accordance with the present invention, the valve means is composed of a valve element which has elasticity and is provided with an air hole in the top portion thereof and a protrusion which opens and closes the air hole.
- According to this configuration, even if the valve element opens and closes repeatedly, the sealing function of the valve element does not decrease. Therefore, the replacement cap can be used for a long period of time, and can be provided at a low cost because the valve means has a simple construction.
- To attain the above object, in the replacement cap for a vessel in accordance with the present invention, the tube is composed of an internal tube and an external tube, and the internal and external tubes are connected to tube connecting portions projectingly provided on the inside and outside of the cap body, respectively.
- According to this configuration, there is no need for forming a through hole for inserting the tube in the cap body, so that there is no fear that the liquid in the vessel leaks from the through hole.
- To attain the above object, in the replacement cap for a vessel in accordance with the present invention, the length of the internal tube is set so that the tip end of the internal tube reaches a position near the inside bottom portion of the vessel, and a sucking member installed at the tip end of the external tube consists of a nipple.
- According to this configuration, the liquid in the vessel can be drunk without leaving the liquid, and also the liquid in the vessel that is contained in a rucksack etc. can be drunk by increasing the length of the external tube. Further, even a patient etc. who are in a bedridden state can drink the liquid in the vessel through the external tube without raising himself/herself Therefore, the replacement cap for a vessel in accordance with the present invention can contribute greatly to nursing of a sick person.
- To attain the above object, in the replacement cap for a vessel in accordance with the present invention, a nipple is installed at the tip end of the external tube.
- According to this configuration, by mounting the cap body on a nursing bottle, the replacement cap can be used to feed milk to an infant. Also, since the infant takes down less air due to the internal tube reaching the inside bottom portion of the vessel, there is scarcely a need for belching after feeding milk.

vessel 1 is stopped, thevalve element 10 a returns to the position indicated by the imaginary line in FIG. 7, and hence theair hole 10 c in thevalve element 10 a is closed by theprotrusion 10 b. Therefore, even if thevessel 1 is laid down or turned down mistakenly, the liquid in thevessel 1 does not leak from thesuction port 4. - In the above-described embodiment, explanation has been given of the case where the replacement cap is used by mounting the
cap body 2 on themouth portion 1 a of thevessel 1 such as a PET bottle. However, the replacement cap can also be used for feeding milk by installing anipple 12 as shown in FIG. 8 at the tip end of theexternal tube 5 b and mounting thecap body 2 on the mouth portion of a nursing bottle. - Although the
cap body 2 is mounted on themouth portion 1 a of thevessel 1 such as a PET bottle in the above-described embodiment, thevessel 1 of PET bottle sometimes has themouth portion 1 a with a different diameter. In this case, it is a matter of course that the same effect can be achieved by providing an adapter fit for that diameter and connecting thecap body 2 to themouth portion 1 a via this adapter. - Also, although the
tube 5 is formed of a silicone material in the above-described embodiment, thetube 5 may be formed of a soft elastomer or the like. - Further, in the above-described embodiment, the
external tube 5 b may be too long and be a hindrance. In such a case, the end portion of theexternal tube 5 b is fixed on the clothing or the like with a fixing member such as a clip, by which theexternal tube 5 b can be prevented from being a hindrance. - As described above in detail, according to the present invention, the cap body of the replacement cap, which is constructed so that the liquid in the vessel can be drunk through the tube, is provided with the air supply port having the valve means which is closed normally and is opened to supply the outside air into the vessel when the interior of the vessel becomes at a negative pressure. Therefore, not only the liquid in the vessel can be drunk by sucking the tip end of the tube but also the liquid in the vessel can be drunk smoothly because the valve means is opened to supply the outside air into the vessel when the interior of the vessel becomes at a negative pressure. In addition, since the air supply port is normally closed by the valve means, even if the vessel is laid down or turned down mistakenly, the liquid in the vessel does not leak, so that there is no fear that the leaking liquid soils clothes etc.
- Also, since the valve means is composed of the valve element that has elasticity and is provided with the air hole in the top portion thereof and the protrusion that opens and closes the air hole, even if the valve element opens and closes repeatedly, the sealing function of the valve element does not decrease. Therefore, the replacement cap can be used for a long period of time, and can be provided at a low cost because the valve means has a simple construction. Also, since the tube is composed of the internal tube and the external tube, and the internal and external tubes are connected to the tube connecting portions projectingly provided on the inside and outside of the cap body, respectively, there is no need for forming a through hole. Therefore, there is no fear that the liquid in the vessel leaks out through the through hole.
- Further, since the length of the internal tube is set so that the tip end of the internal tube reaches a position near the inside bottom portion of the vessel, and the sucking member is installed at the tip end of the external tube, the liquid in the vessel can be drunk without leaving the liquid, and also the liquid in the vessel that is contained in a rucksack etc. can be drunk by increasing the length of the external tube.
- Moreover, if a nipple is installed at the tip end of the external tube, by mounting the cap body on a nursing bottle, the replacement cap can be used to feed milk to an infant. Also, since the infant takes down less air due to the internal tube reaching the inside bottom portion of the vessel, there is scarcely a need for belching after feeding milk.
