Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dispensing cap, and more particularly, to an improvement of a dispensing cap in which a cover plate is hinged so as to be freely opened and closed by an inverted hinge mechanism.

[0002]

[Prior art]

[Problem to be solved by the invention]
The upper rear end of the cap base and the lower rear end of the lid are connected by a pair of hinges provided at a predetermined interval, and formed between the hinges, and the upper end is located at the center of the rear end of the lid top wall via the hinge. A so-called three-point hinge in which an inverted L-shaped plate-shaped elastic plate whose lower end is connected to the center of the rear wall of the cap base via a hinge is provided and the lid is connected to the cap base so that it can be elastically inverted. One having an inverted hinge mechanism called a so-called inverted hinge mechanism is known. In addition, these caps are configured so that a plug projection vertically provided from the back surface of the lid top wall can be detachably fitted into a pouring hole formed in the top wall of the cap base.
The lid is opened by pushing up a finger hook projection protruding from the front surface of the cap.

[0003] When the cap is opened or closed to a predetermined position, the cap is automatically opened or closed by the action of a reversing hinge mechanism, and the closed state or the open state can be stably maintained, so that handling is convenient. In addition, the plug projection can be formed at a low cost because it can be formed by integral molding of a synthetic resin, but the plug projection is generally fitted tightly into the pouring hole in order to maintain good liquid tightness. Since it requires a force when the plug projection comes off from the pouring hole, in addition to the urging force in the closing direction of the elastic plate up to the inversion boundary position at the time of opening the lid,
A relatively large force is required initially when the lid is opened.

[0004] Generally, the finger-hung projection of this type of cap has a small projection width due to the reason that the appearance of the cap is improved or that a normal capper can be used at the time of liquid filling so that the cap can be placed on an existing filling line. Due to the configuration, there is a disadvantage that it is difficult to open relatively easily. In addition, when opening the lid, the reversing hinge mechanism does not act in the opening direction unless the lid is opened to a position having a relatively wide opening angle. Difficult to open body.

The present invention has been made in view of the above points, and in this kind of cap, the lid can be easily opened with only one hand holding the container, and even if the container is accidentally turned down. An object of the present invention is to provide an excellent pouring cap which does not cause a disadvantage that the lid is opened and the contents liquid leaks.

[0006]

In order to solve the above-mentioned problems, a cap according to the present invention comprises a pair of hinges 12, 12 provided at a predetermined interval between a rear upper end of a cap base 2 and a rear lower end of a lid 3.
And the upper end between the hinges 12 and 12 is covered with the lid top wall 6.
An inverted L-shaped elastic plate 15 connected to the center of the rear part via a hinge 13 and connected to the lower end of the cap base peripheral wall 5 via a hinge 14 at the center of the rear part of the cap base is provided. In the spout cap connected in a reversible manner, a portion from the front part to the rear part of the outer peripheral edge of the base top wall 6 is formed so as to be depressed downward, and the bottom surface is gradually raised from the front part to the rear part. A pair of left and right recesses 16 formed on the inclined surface 16a,
16 is provided, one end is integrally connected to the inside front end of each of the recesses 16, 16 and extended along the outer edge of each of the recesses 16, 16;
A pair of left and right elastic claws 17, 17 having a flat upper surface located at the same level as the upper surface of the base and an inclined surface having a lower surface in contact with the inclined surfaces 16 a are provided.

[0007]

[Function] When the outer surfaces of the elastic claws 17, 17 are pressed toward the center side when the lid is opened, the elastic claws 17, 17 are elastically deformed so as to be reduced in diameter. The cap projection 2 can be easily penetrated into the wedge shape between the upper surface of the cap base 2 and the plug projection 11 which requires a relatively large force at the time of opening the lid from the pouring hole 7 easily. 4. It is possible to push up to the opening position of 4 (that is, the opening angle at which the force acts in the direction of returning to the original state after elastically deforming in the direction in which the inverted L-shaped elastic plate spreads), so that one hand holding the container Easy opening of the lid is possible only with this.
