[Industrial applications]

 The present invention relates to a pouring cap, and more particularly, to an improvement of a pouring cap in which a lid plate is hinged so that it can be opened and closed by an inversion hinge mechanism.

[0002]

[Prior art] [Problems to be solved by the device]

 As a pouring cap, the upper end of the rear part of the cap base and the lower end of the rear part of the lid are connected by a pair of hinges provided at a predetermined interval, and the upper end is formed between the hinges and the upper end is the rear part of the lid top wall. An elastic plate in the shape of an inverted L-shaped plate, which is connected to the center via a hinge and the lower end is connected to the center of the rear wall of the cap base via a hinge, allows the lid to be elastically inverted to the cap base. It is known to have an inversion hinge mechanism called a so-called three-point hinge that is connected. In addition, these caps are constructed so that the plug projections hung from the back surface of the lid top wall can be detachably fitted into the pouring holes formed in the top wall of the cap base, and the finger hook projections projected on the front surface of the cap. The lid is configured to open by pushing up.

When the cap is opened or closed to a predetermined position, it is automatically opened or closed by the action of the reversing hinge mechanism, and the closed state or the opened state can be stably maintained. It is easy to handle and can be manufactured at low cost because it can be formed by integral molding of synthetic resin.However, the plug projections generally fit tightly into the spout hole to maintain good liquid tightness. The elastic plate is biased in the closing direction up to the inversion boundary position when the lid is opened, and in addition to the force required to remove the plug projection from the pouring hole, Requires relatively large force.

Generally, the finger hooking protrusion of this type of cap has a small protruding width for the reason that it makes the cap look good, or that it can be used on a ready-made filling line by using a normal capper when filling the liquid. It has a drawback that it is relatively easy to open. In addition, when opening the lid, this type of cap does not work in the opening direction because the reversing hinge mechanism does not work in the opening direction unless the lid is opened to a position where the opening angle is relatively wide. It is relatively difficult to open the lid by itself.

The present invention has been made in view of the above points, and in this type of cap, the lid can be easily opened with only one hand holding the container, and moreover, the container may be accidentally collapsed. Also proposes an excellent pouring cap that does not cause the inconvenience that the lid opens and the content liquid leaks out.

[0006]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the cap of the present invention connects the upper end of the rear part of the cap base 2 and the lower end of the rear part of the lid 3 with a pair of hinges 12 and 12 provided at a predetermined interval, and an upper end between the hinges 12 and 12. Is connected to the rear center of the lid top wall 6 via a hinge 13, and the lower end is connected to the rear center of the cap base peripheral wall 5 via a hinge 14 to provide an elastic plate 15 in the shape of an inverted L-shaped cover 3 In the pouring cap in which the cap base 2 is connected to the cap base 2 in an elastically reversible manner, the base peripheral wall of the base base 6 is formed by denting the part from the front part to the rear part downward, and the bottom surface thereof is A pair of left and right recesses 16 and 16 are formed on the inclined surface 16a that gradually rises from the rear part to the rear part, and one end is integrally connected to the front end part of each of the above recesses 16 and 16 along the outer edge of each recess 16 and 16. Is flat and the upper surface is at the same level as the upper surface of the base. Which is configured by providing a pair of elastic claws 17, 17 forming an inclined surface in contact with the respective inclined surfaces 16a.

[0007]

[Action]

 When opening the lid, if the outer surfaces of both elastic claws 17 and 17 are pressed toward the center side, the elastic claws 17 and 17 elastically deform so as to reduce the diameter inward, and the tip ends of the elastic claws 17 and 17 and the rear lower surface of the lid peripheral wall 9 and the cap base. It enters into a wedge shape between the upper surface of the base 2 and the plug projection 11 at the beginning of opening, which requires a comparatively strong force, and can be easily removed from the pouring hole 7. Since it can be pushed up to the opening action position (that is, the opening angle where the force acts in the direction in which the inverted L-shaped elastic plate elastically deforms in the expanding direction and then returns to the original state), only one hand holding the container The lid can be easily opened.

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

1 to 7 show an embodiment of the present invention, in which 1 denotes a pouring cap. In the cap 1, a cap 3 is connected to a cap base 2 via a reversing hinge mechanism 4 so as to be elastically reversible.

The cap base 2 is in the shape of a horizontally elongated elliptic cylinder having an open lower end surface in which a top wall 6 extends from the upper end of the peripheral wall 5, and a short tubular spout hole 7 having a base end opened approximately at the center of the top wall 6. The top wall 6 is provided with a threaded cylindrical portion 8 at the center of the rear surface thereof so as to be screwed to the mouth and neck of the container body to be mounted.

The lid 3 has a top wall 10 extending from an upper end of a peripheral wall 9 having a horizontally long elliptic cylinder whose lower end is in contact with a peripheral portion of the top surface of the cap base. A plug projection 11 is detachably and tightly fitted into the pouring hole 7 so as to project.

Further, the reversing hinge mechanism 4 connects the upper end of the rear portion of the cap base 2 and the lower end of the rear portion of the lid body 3 with a pair of hinges 12, 12 provided at a predetermined interval. An inverted L-shaped plate that is formed between 12 and has its upper end connected to the rear center of the lid top wall 10 via a hinge 13 and its lower end connected to the rear center of the cap base peripheral wall 5 via a hinge 14. This is a well-known mechanism that is configured by providing an elastic plate 15 that forms a unit and is integrally formed.

In the present invention, a pair of left and right recesses 16 and 16 are formed by recessing a portion from the rear portion to the front portion of the outer peripheral edge portion of the cap base top wall 6 downwardly. Elastic claws 17 and 17 are housed in 16 and 16, respectively.

The recesses 16 and 16 originate at both sides of the pair of hinges 12 and 12, extend along the outer peripheral edge of the base 2, and are displaced outward from the center of the front outer peripheral edge of the base. The bottom surface of the bottom surface forms an inclined surface 16a which is gradually raised from one end of the front portion and is substantially level with the top surface of the top wall 6 at the other end of the rear portion. In this embodiment, the inclined surface 16a is also inclined outward so that the elastic claws 17 can easily slide.

Further, the elastic claw 17 has a flat arcuate band shape in which the base end portion is integrally connected to the front end portion end surface in the recess 16 and reaches the rear end portion along the side edge of the recess 16 and the upper surface thereof is the base. The upper surface of the top wall 6 has a flat surface substantially at the same level as that of the upper surface, and the lower end surface thereof is an inclined surface that abuts the inclined surface 16a. When the outer surfaces of the elastic claws 17, 17 are pressed toward the center from both sides, the elastic claws 17, 17 are guided by the inclined surfaces 16a, 16a and elastically deformed inward, and the tips thereof are inclined. It is configured so as to project further inward and upward so as to enter between the lower surface of the rear portion of the lid peripheral wall 9 and the upper surface of the base 2, and push up the rear portion of the lid body 3 to open the lid body 3.

In this embodiment, as shown in FIG. 7, the cap 1 is composed of two members A and B.

Reference numeral 18 in the drawing denotes a rib, and all the above members are made of synthetic resin.

[0018]

[Effect of device]

 As described above, the cap of the present invention has the above-described configuration, so that the elastic claws can be easily opened by pushing in from both sides, and the lid can be easily opened with only one hand holding the container. Becomes

Further, since each elastic claw is housed so that it can be pushed into the concave portion of the cap base, even if the container is accidentally tilted, there is a disadvantage that the lid opens and the content liquid leaks out. There is no fear.
