JPH0748529Y2 - Elastic inverted cap - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial field of application" The present invention relates to a three-point hinge-type elastic inversion type cap that has a spout and is attached to the mouth of a container.

"Prior Art" This type of cap is very well known, and a canopy having a rod plug for opening and closing the pouring hole is provided on the upper surface of the cap body having a pouring hole on the top wall, and three points on the rear side. The canopy is integrally connected with a thin hinge so that it can be opened. By doing so, two stable points where the two turning loci delineated by the common turning hinge of the canopy and the elastic inversion plate intersect are provided, and the open / closed state of the canopy is positioned at these stable points. It is used in various containers because it can be formed with one member and the pouring hole can be opened and closed with one touch.

"Problems to be solved by the invention" This type of cap opens the canopy via the knob on the free end of the canopy when pouring out the contents, and the pouring plug is opened with this lid. Since the knob sticks out from the outer surface of the cap, if the knob is hooked on something at the distribution stage, etc., the cap may open and the contents may flow out.

The present invention is to provide a lock mechanism for unlocking the canopy by a simple operation, and to obtain a safe elastic inversion type cap that does not open or open the cap unless the lock mechanism is unlocked.

[Means for Solving the Problem] The elastic inversion type cap of the present invention forms an upward lock groove 2 which dents the central portion of the top wall 1 into a flat box shape and hangs downward, and which is poured on the front portion. On the upper surface of the main body 4 having the holes 3, the central portion is recessed in a cup shape, and the through hole 5 which overlaps with the lock groove 2 is opened in the central portion, and the lower surface of the front portion is covered with the through hole 5. Install a canopy 7 with a rod stopper 6 that opens and closes the pouring hole 3
The lock plate 8 is integrally arranged so that it can be opened by a point hinge, and the thin plate-like lock plate 8 is inserted into the lock groove 2 through the through hole 5 so as to be removable.

"Operation" In the above, the canopy 7 is normally closed as shown in Fig. 1a and Fig. 2a, and the rod plug 6 is inserted into the pouring hole 3 by this closing and the pouring hole 3 is closed. It is sealed. The lock plate 8 is inserted into the lock groove 2 on the main body 4 side through the through hole 5 of the canopy 7 to lock the opening of the canopy 7.

That is, even if the canopy 7 is to be opened via the knob 9 at the free end thereof, the canopy 7 is opened one-sided, that is, the canopy 7 is pivotally opened with the fulcrum hinge 10a at the rear end edge as a fulcrum to open the canopy 7. It cannot be rotated by abutting against it and its lid is locked.

Here, in order to open and close the cap, it is necessary to open the cap as shown in FIG.
As shown in the two-dot chain line in Fig. A and Fig. 1b, the lock plate 8 is pulled out so that its lower end does not come into contact with the lock groove 2 of the top wall 1, and in this state, the canopy 7 is opened and poured by this open. The tap may be opened. It is preferable to pull up the lock plate 8 to be in an unlocked state at normal times, that is, except when the opening of the canopy 7 is locked.

Embodiment An embodiment of the present invention will be described below with reference to the drawings. In each drawing, 4 is a main body of the cap, 7 is a canopy integrated with the main body 1, and 8 is a lock plate.

The main body 4 has a cap-like shape, and the central portion of the top wall 1 is recessed into a flat rectangular box shape to form an upward lock groove 2 that hangs downward, and a pouring hole 3 is opened in the front portion. A peripheral wall 11 for attachment is attached by screwing the peripheral wall 11 for attachment to the outer surface of the mouth / neck portion 13 of the container body 12.

The canopy 7 has a shape in which a penetrating peripheral wall 14 is hung from the peripheral edge of a cup-shaped concave top plate, and a through hole 5 that overlaps with the lock groove 2 is opened in the center of the top plate, and the front bottom surface is the above-mentioned. A rod plug 6 to be inserted into the pouring hole 3 is hung down, and a rear portion side on which an inverted L-shaped elastic reversal plate 15 is formed is attached to a main body portion 4 by three-point hinges 10a, 10b, 10c.
It is integrally formed on the upper surface so that it can be opened.

It should be noted that engaging projections 16, 16 are provided on both inner circumferential surfaces in the longitudinal direction of the peripheral edge of the through hole 5 of the canopy 7, and the engaging grooves are provided directly below the engaging projections 16, 16.
17,17 are recessed. 9 is a knob.

The lock plate 8 is a rectangular flat plate, and has knobs 18 and 18 projecting from the upper ends of both sides thereof, and the engaging projections 16 and 16 are forcedly crossed over the lower end lower surface in the longitudinal direction to engage the engaging groove 17. Engaging projections 19 and 19 that engage with the projections 17 are provided so as to be inserted into the lock groove 2 through the through hole 5 so as to be removable. This lock plate 8
Means that the engaging projections 19, 19 at the lower end are locked to the engaging projections 16 and 16 and do not come out when pulled upward for unlocking,
In this state, the engaging projections 19, 19 engage with the engaging grooves 17, 17, so that the locking release state can be maintained without any downward drop and locking.

Therefore, when the lock plate 8 is inserted into the lock groove 2 at all times, the lock plate 8 prevents the canopy 7 from rotating,
The canopy 7 can be opened and the pouring plug can be opened. When the lock plate 8 is pulled up to the upper limit, the canopy 7 is unlocked and the lid can be opened and opened.

Each of the above parts is molded and manufactured from a synthetic resin material.

[Advantage of the Invention] As described above, according to the present invention, the upward lock groove 2 is formed on the top wall 1 of the main body 4 so as to hang downward, and the canopy 7 has a cup-shaped central portion with a recess. Open the through hole 5,
A lock plate 8 is removably attached to the lock groove 2 through the through hole 5, and a lock that allows the canopy 7 to be opened, and thus the pouring plug to be opened, only when the lock plate 8 is pulled up from the lock groove 2. Since the mechanism is provided, it is possible to obtain the elastic inversion type cap in which the canopy 7 is not opened during the distribution process. Moreover, the lock mechanism is simple by the lock groove 2 and the lock plate 8, and the operation can be performed simply by inserting and removing the lock plate, without any trouble.
