Abstract

PROBLEM TO BE SOLVED: To provide a container cap equipment which can surely prevent pseudo-adhesion in a valve body slit. SOLUTION: This cap equipment is provided with a valve body 5 whose wall is made of soft and flexible resin such as silicone resin forming, in a recess 5d at the inside of a top part 5a, a slit 4 which opens/closes depending on the inner pressure of the container, a cap main body 7 which holds a condition where the top part 5a of the valve body 5 faces outside from the opening part 6 and which is fixed at the opening base part 2 of the container 1, and an over cap 8 which covers freely detachable the opening part 6. When the overcap 8 fits the opening part 6 and covers a protrusion 9 facing upward (outward) around the periphery of the valve body slit 4, the slit 4 opens being pressed by the flat bottom part 8a of the over cap 8.

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 difficult to use, as the product leaked out.

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.

ができない問題点があった。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. In other words, after the silicone rubber is molded into the valve body, the top is cut open with a cutter or the like and mounted on the container. However, a phenomenon (pseudo-adhesion) may occur in which the cut slit is reattached over time. When this pseudo-adhesion occurs, the slit cannot be partially or completely opened, so that there is a problem that the liquid product cannot be sufficiently poured out when used.

Therefore, if the overcap is left covered by the overcap, the slit is formed. Even after a long time, the slits do not pseudo-adhere. In addition, since the protrusion is formed outward around the slit, the liquid product remaining on the surface of the slit forming portion of the valve body is blocked by the protrusion, so that the liquid product remains at the top of the valve body even if the container is tilted. There is no spillage, so that dripping can be reliably prevented. In addition, even if the valve element is likely to be torn from the slit due to use or the like, since the projections protrude in the thickness direction and are thick, the tearing is stopped by the projections, so that the valve element is reliably prevented from being torn. it can.
