と液が漏れたりする等、使いにくかった。2. Description of the Related Art Conventionally, a user purchases a liquid product such as a kitchen detergent in a container. Then, the user opens the cap at the upper end of the container when using the liquid product, and then squeezes the container with the container opening facing downward, thereby causing the liquid product to be poured into the place of use. This cap is usually of the type that opens and closes the liquid passage of the cap body provided at the mouth of the container.However, it is not easy to run out of the liquid, or the liquid is simply turned upside down and the mouth of the container is turned downward. It was not easy to use, as the product leaked out or the liquid leaked if carelessly knocked down.

しないようにしていた。In view of the above, a valve body made of a flexible silicone rubber wall having a slit and provided to open and close in response to the pressure in the container is provided on the cap body, and the slit of the valve body has a certain pressure. Was designed so that it would not open unless it was added, so that the liquid product would not leak when the container was inverted.

い恐れが生じる。However, there are the following problems in order to store a liquid product in a container using the above-mentioned valve body and make it into a commercial product. That is, after the silicone rubber is molded, the top of the valve body is cut open with a cutter or the like and attached to the container. However, in the container, stress is applied to the cut end of the slit by opening and closing the valve body slit when the liquid product is poured out. Due to this, a slit may be extended from the cut end in the slit, and the slit may be large.Therefore, in the container, the liquid product is poured out more than expected over time. May not be able to achieve the designed performance.

する等の欠点が生じる。[0005] On the other hand, in order to prevent the slit from being cut off, simply designing the wall thickness of the valve body to be thick requires a strong press of the container to open and close the valve body and increase the internal pressure thereof. In addition, the user cannot use it comfortably. In particular, a user with a low grip force has difficulty in dispensing the liquid product, causing drawbacks such as the inability to dispense a required amount and a long time.
