Abstract

PURPOSE: To provide a closure unit which has an appropriate strength and can stably pour a sufficient quantity of fluid without increasing its weight. CONSTITUTION: This closure unit consists of substantially a tubular pouring part 11 and a closure part 12 which opens and closes a pouring mouth 30 of the pouring part 11, and on the inside of the pouring part 11 at least one rib 26-29 is protrudingly formed in the direction of fluid flowing in pouring. Since the ribs 26-29 are provided, the fluid is guided by the ribs 26-29 and poured in stable flow along the ribs 26-29 when the fluid is poured. And, the ribs 26-29 reinforce the pouring part 11. The reinforcement of the pouring part 11 by the ribs 26-29 allows to reduce the wall thickness of the pouring part 11.

Description of the Related Art Conventionally, in a container formed of, for example, a metal can or a cardboard whose inside is coated with a fluid such as a liquid, a lid is provided so that the spout can be repeatedly opened and closed. The lid includes a spout portion having a spout and a lid portion that opens and closes the spout. The lid is used by being fitted into an opening formed in the container, and a thermoplastic material is used as the material (Swiss patent application No. 2739 / 91-2).

動体を安定して注出することができない。However, in the conventional lid of the container, the cross-sectional area of the spout is set to be small, so that a sufficient amount of the fluid cannot be stably dispensed. .. That is, when the cross-sectional area of the spout is increased, the strength of the spout is reduced and the spout is deformed each time a load is applied. Therefore, it is conceivable to increase the wall thickness of the spout to increase the strength, but in this case, the weight of the lid body increases. Therefore, the cross-sectional area of the spout is usually set to be small, and as a result, a sufficient amount of fluid cannot be stably spouted.

きる容器の蓋体を提供することを目的とする。Further, since no special guide for pouring the fluid is provided, the fluid is poured through various portions of the pouring port. Therefore, the pouring of the fluid becomes unstable and may be poured through an unintended portion. The present invention solves the above-mentioned problems of the lid of the conventional container, has an appropriate strength without increasing the weight, and is capable of stably pouring out a sufficient amount of fluid. The purpose is to provide a lid.

And, it is composed of a substantially cylindrical spout portion and a lid portion that opens and closes the spout of the spout portion, and the inside of the spout portion is at least one in the flowing direction of the fluid during pouring. Two ribs are formed protruding.

Has at least one rib protruding in the direction in which the fluid flows when it is poured. Since the ribs are provided, the fluid is guided by the ribs when being poured, and is poured in a stable flow along the ribs.

Therefore, even if the cross-sectional area of the spout of the spout is increased, the spout will not be deformed each time a load is applied as the lid is opened and closed. Therefore, a sufficient amount of fluid can be stably poured out. Further, since the spout portion is reinforced by the rib, the wall thickness of the spout portion can be reduced.

Further, a reinforcing member may be provided at the spout portion. In this case, the reinforcing member may be provided at a corner of the spout, and the box part may be formed together with the wall of the spout. Since the box portion also increases the strength of the spout portion, the wall thickness of the spout portion can be reduced.
