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. So-called three-point hinge in which an elastic plate in the form of an inverted L-shaped 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 out, and has no inconvenience such as accumulation of water in the concave portion.

[0006]

In order to solve the above-mentioned problems, the cap of the present invention is closely fitted removably to the cap base 2 having a top wall 8 having a pouring hole 10 formed therein. Plug projection
In a pouring cap in which a lid 3 having a 17 vertically suspended from a top wall 16 is hinged so as to be openable and closable by a reversing hinge mechanism 4,
A push button 5 having a sliding plate portion 23 that slides on the upper surface of the cap base 2 is provided.
And the front portion of the lid 3 closed by the tapered portion 25 is formed so as to be able to be pushed up, and the front end of the push button 5 is projected so as to be able to be pushed into the recess 9 provided on the front surface of the cap base 2. A projection 27 is provided at the rear edge of the sliding plate portion 23 so as to be in contact with the back surface of the reversing hinge mechanism.
When the sliding plate portion 23 retreats by pressing the front edge of the lid, the tapered portion 25 pushes up the front portion of the lid,
The rear surface of the reversing hinge mechanism is pressed by the projection 27 to open the lid, and the concave bottom wall 9a is provided with a through hole 14 for draining water.

[0007]

When the front edge of the pressing plate portion 24 of the push button 5 is pressed at the time of opening the lid, the sliding plate portion 23 retreats integrally, and the lid 3 is pushed up by the tapered portion 25, so that a relatively strong force is exerted. Can be easily removed from the pouring hole 10 of the plug projection 17 at the time of opening the lid, and the projection 27 presses the rear surface of the reversing hinge mechanism 4 to open the lid opening position of the reversing hinge mechanism 4 (that is, the reverse L position). It can be pushed up to the opening angle where the force acts in the direction to return to the original state after elastic deformation in the direction in which the letter-shaped elastic plate spreads)
Easy lid opening with only one hand holding the container is possible.

Further, even when a shower or the like is applied to the cap 1 in the open state from above, water does not flow down from the through-holes 14 quickly and accumulate in the recess 9.

The push button 5 has a sliding plate portion having a long hole 22 formed at the center thereof for escape of the pouring hole 10 and having the upper surface of the cap base 2 slidably forward and backward. A pressing plate portion 24 is provided so as to extend from a front edge of the plate portion 23 to a front end portion in the recess 9.

A tapered portion 25 is formed at the front end of the upper surface of the sliding plate portion 23 so as to become lower toward the trailing edge. The tapered portion 25 is recessed in the central lower surface of the front part of the cover peripheral wall 15. The inclined surface of the tapered portion 25 is fitted into the concave portion 26 having the
It is configured to push up the top surface. In addition, this taper part
25 is not limited to being provided at the front end of the upper surface of the sliding plate portion 23, and may be provided at the front position of the sliding plate portion retracted backward from the front end of the upper surface of the sliding plate portion 23. In this case, for example, it is preferable to protrude the protruding portion from the position facing the tapered portion 25 on the back surface of the base top wall 8.

A projection 27 is formed on the rear edge of the sliding plate 23. The projection 27 has a shape as if the rear edge of the sliding plate 23 is bent upward. It is located near the rear surface, and is configured such that when the sliding plate portion 23 retreats, it comes into contact with the reverse hinge mechanism 4 rear surface.

[0019]

As described above, the cap of the present invention pushes up the front portion of the lid 3 with the tapered portion 25 when the sliding plate portion 23 retreats by pressing the front edge of the push button.
Since the rear surface of the reversing hinge mechanism 4 is pressed by the projection 27 to open the cover, the pushing force of the push button 5 is small, and the push button 5 only needs to be pushed backward from the front of the cap base 2. The lid can be easily opened with only one hand holding the container.

The front end of the push button 5 is provided on the cap base 2.
Because it protrudes into the recess 9 on the front face so that it can be pushed in,
Even if the container is accidentally overturned, there is no fear that the lid is opened and the contents liquid leaks.

Further, the water entering the recess 9 can be quickly discharged to the outside through the drain hole 14.
The disadvantage that a large amount of water accumulates in the recess does not occur.
