Description

[Detailed Description of the Invention] (a) Field of the Invention The present invention relates to a container with a straw, that is, a container in which the liquid inside the container body is sucked through a straw.

(b) Prior art and its problems Conventionally, containers that use a straw for drinking have been constructed by sealing the opening of the container body with a lid, and then inserting the straw into a through hole in the lid in a watertight manner. It is usually inserted and sucked. However, in this case, the inside of the container becomes negative pressure as it is sucked, so there is a drawback that continuous sucking is not possible.

Therefore, as described in Japanese Utility Model Publication No. 57-48425, a device is provided in which a straw is attached to the main body and a ventilation hole is provided in the upper surface of the main body into which the drinking spout of the straw can be inserted detachably.

With this configuration, air can flow freely through the vent when drinking, preventing negative pressure and allowing continuous sucking.On the other hand, when not in use, the drinking mouth of the straw can be used to close the vent. By closing the container, liquid leakage can be prevented even if the container falls over.

However, with this container, after drinking, the drinking straw is inserted into the container through the ventilation hole, which causes the drinking straw to come into contact with the liquid in the container, resulting in unsanitary conditions. There was a drawback.
In addition, since the inner surface of the vent hole leaks liquid, limescale and dust tend to accumulate, and when a straw is inserted into the vent hole, limescale and dust also fall into the container, making it even more unsanitary.

(c) Purpose of the invention The present invention was made in view of the above drawbacks, and it not only allows continuous suction, but also prevents the inside of the container from becoming unsanitary, and also has a straw that covers the straw when not in use. The purpose is to provide a container.

(d) Structure of the device In order to achieve the above purpose, the device has two parts on the lid body.
A straw is penetrated and held in one of the through holes in a watertight manner, and an air passage gasket that forms an air passage is attached to the other through hole, and the air passage of this air passage gasket is opened and closed. , a cap that covers and releases the straw protrusion on the top of the lid is rotatably attached to the lid.

(E) Description of Embodiments The present invention will be described below with reference to the attached drawings which are embodiments.

1 to 3 show a first embodiment of the present invention,
The container body 1 has an open top surface, and this opening 2
A lid 10 is screwed onto the container via a seal ring 3, and the opening 2 of the container body 1 is sealed.

The lid body 10 has a flat part 19 and a bulging part 20 having a cross section of approximately 1/4 arc on the upper surface, and the flat part 19 is provided with a through hole 11 and a recess 18,
A flexible straw 14 is inserted into the through hole 11 through a seal packing 13 so that its lower end extends to the vicinity of the bottom of the container body 1, and the other end (drinking spout) 14b protrudes to the outside of the container body 1. installed in a watertight manner. Further, a through hole 12 to which an air passage packing 15 is attached is formed at the top of the bulging portion 20. Further, a cap 21 is rotatably attached to the outer surface of the lid 10 by a rail portion 20a, and a window hole 21a is provided in one side of the cap 21.
is formed.

Therefore, when the cap 21 is rotated toward the bulge 20 as shown in FIG. 1, the straw 14 is exposed through the window hole 21a, and the air passage 15a of the air passage packing 15 is also exposed. Therefore, straw 1
When the mouth 14b of No. 4 is pulled out from the recess 18 and sucked, outside air is introduced into the container through the ventilation path 15a, and the container can be sucked continuously. When you have finished sucking, insert the drinking spout 14b of the straw 14 into the recess 18, and insert the cap 21 so that its window hole 21a is aligned with the bulge 2.
It is only necessary to rotate it to the position corresponding to 0 (see Fig. 3). As a result, the air passage 15a is sealed with the inner surface of the cap 21, and the upper part of the straw 14 is covered with the cap 21, so that liquid does not leak even when carried, and the straw 14 is also protected, preventing accidental accident. It does not come out of the recess 18.

FIG. 4 shows a second embodiment of the present invention. Similar to the first embodiment, a flat part 19 and a bulging part 20 are provided on the top surface of the lid 10, and the straw 14 is held through the flat part 19. At the same time, an air passage packing 15 is attached to the top of the bulging portion 20. On the other hand, a cap 21 is attached to the outer surface of the lid 10 so as to be openable and closable using a shaft support 23 as a fulcrum, and a protrusion 22a that can be freely engaged with and detached from the engagement piece 24 of the lid 10 is provided on the inner surface of the tip end of the cap 21. It is formed. Also, cap 2
A protrusion 22b is formed on the lower surface of the ceiling of the cap 1, and when the cap 21 is closed, this protrusion 22b is formed.
b presses the vent gasket 15 to open the vent passage 1.
5a is closed.

(f) Effects of the invention As is clear from the above explanation, according to the invention, a straw is held through one of the through holes of the lid body, and an air passage packing is attached to the other through hole.
The cap that opens and closes the air passage of the air passage packing and the straw above the lid body is rotatably attached to the lid body, so when the air passage is closed by the cap, the liquid inside will leak out from the air passage. This does not happen at all, and even if the liquid tries to flow out through the straw, a negative pressure is created inside the container, which prevents the liquid from flowing out. On the other hand, when the air passage is opened by the cap, the straw portion is released and outside air flows in through the air passage, allowing continuous suction. In addition, since there is no need to insert the drinking straw into the container as in the case of conventional methods, there is no need for the drinking spout to come into contact with the liquid inside the container, or for limescale or dust attached to the ventilation hole to fall into the container. When in use, the top of the straw is also covered with a cap, which is hygienic and prevents the straw from accidentally coming off.
