Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to an improvement of an elastic inversion type cap.

``Prior Art'' Recently, many containers using elastic inverted caps have been on the market. This cap, as is well known, has a closure plate with a single-opening stopper connected by a flexible hinge;
The spout hole is opened and closed by opening and closing this opening/closing plate via a tongue-shaped knob protruding from the outside of the free end, so it is convenient and can be used while attached without having to be removed from the container body. It is.

``Problem that the invention aims to solve'' As mentioned above, the opening/closing plate has a tongue-shaped knob for opening/closing, which causes the inconvenience of opening the lid if it is hooked on something. There is.

The present invention provides an elastic reversible cap in which the knob is an independent member, rotatably incorporated in the front part of the opening/closing plate, and projected to the front side when the lid is opened, thereby solving the above-mentioned inconvenience.

``Means for Solving the Problems'' The elastic reversible cap of the present invention has a rectangular outer shape, has a spout hole 4 in the top surface, and has an arcuate surface 5 recessed in the upper corner of the front side. , and a cap body 1 having a storage groove 7 recessed in the front surface of a peripheral wall 6; 1
An opening/closing plate 2 is arranged so that it can be opened in one direction on the upper surface, and has a stopper 8 hanging therefrom which is inserted into the spout hole 4 from the back side, and a knob piece 10 is inserted from a base 9 having a circular outer surface that slides on the arcuate surface 5. It has a protruding shape, is pivotally provided at the front edge of the opening/closing plate 2, and is normally attached to the knob 10.
and a knob member 3 that hangs down and is stored in the storage groove 7.

``Effect'' In the above, always refers to Figure 1 a, Figure 3, and Figure 4.
As shown in FIG. 6, the knob piece 1 of the knob member 3
0 hangs down and is stored in the storage groove 7, and does not protrude outward, so this knob piece 1
0 will not get caught on anything, so there will be no chance of the lid being opened accidentally.

Here, when pouring out the contents, put a nail on the tip of the knob 10 and pull it up, then put your finger on this knob 10 and pass the knob 3 through the opening/closing plate 2.
Just open it backwards as shown in Figures 2 and 5. As a result, the stopper 8 comes out of the spout hole 4 and is opened.

``Example'' The elastic reversible cap of the present invention has a cap body 1 having a spout hole 4 on the top surface, a plug 8 to be inserted into the spout hole 4, and is arranged on the top surface of the cap body 1. It consists of a single-opening opening/closing plate 2 coupled with a flexible hinge, and a knob member 3 which is pivotally supported on the front edge of the opening/closing plate 2 and normally hangs down along the front surface of the cap body 1.
Molded and manufactured from synthetic resin material.

First Embodiment (FIGS. 1 to 3) In the cap body 1, a storage groove 7 is formed in the upper front surface of a rectangular peripheral wall 6, and a round mounting peripheral wall 11 is formed inside the rectangular peripheral wall 6. Although not shown, it is screwed onto the outer surface of the mouth and neck of the container body through this mounting peripheral wall 11. 12 is a vertical ring that fits into the mouth and neck when worn. Further, an engaging portion 13 having a flat upper surface whose top surface extends forward is formed projectingly at the center of the arcuate surface 5 at the upper corner of the front surface, and its front edge is an engaging protrusion 14 .

The opening/closing plate 2 has a stopper 8 in the center of the back surface, and supports 15, 15 on both sides of the front end.
15 and the top plate of the opening/closing plate, and cut the lower half of the middle part to form a semi-shaft part 16.
A supporting shaft 17 is passed. A flat lower surface of the semi-shaft portion 16 is joined to a flat upper surface of the engaging portion 13 .

This opening/closing plate 2 has an inverted L-shaped strip-shaped separating piece 18 on the rear connecting side, and this is attached to three flexible hinges 1.
9a, 19b, and 19c show an elastic reversible type using a well-known three-point hinge connected to the cap body 1. Therefore, this state can be maintained in the closed state of FIGS. 1 and 3, and This state can be maintained even in the open state shown in Figure 2. In the illustrated example, a three-point hinge type is shown, but of course other types of elastic inversion types may be used. For example, there is one flexible hinge, and there are two hinges on both sides that can be reversed and maintained in the same state by opening and closing.
The same applies to those with paired legs.

The base 9 of the knob member 3 has a semi-cylindrical shape with the middle part of one side cut out, and both sides of the base 9 are rotatably fitted to the outer surface of the round shaft on both sides of the support shaft 17 through the gap. are doing. There is an engagement protrusion 20 that engages with the engagement protrusion 14 in the notch on the inner surface side of the proximal end of the flat tab piece 10 of this member 3, and these engagement protrusions 14, 20 are stopped. The grip piece 10 can be held in a hanging state as shown in FIG. 1A by engagement thereof. In addition, the outer surface of the base 9 has a flat cut surface 2.
1, so that the upper surface of the opening/closing plate 2 and the upper surface of the knob member 3 are flush with each other when the lid is closed. When the lid is opened, the knob 10 is held in an outwardly protruding state as shown in FIG. 1b.

Second Embodiment (FIGS. 4 to 6) In this embodiment, the shape of the knob member 3 and its mounting structure are changed. That is, the support parts 1 on both sides
5 and 15 are formed with small-diameter pivot grooves 22, 22, 23, and 23 (not visible in the figure) on the opposite side of the axis and on the outside thereof, and these pivot grooves are formed with outward-expanding guide grooves, respectively. The grooves 24, 24, 25, 25 allow the knob member 3 to pass through to the lower side, while the base 9 of the knob member 3 is a cylindrical body, and from both end faces of the base 9, a thick shaft 26,
26 are protrudingly provided, and these are forcibly passed through the guide grooves 24, 24, 25, 25 and rotatably supported in the pivot grooves 22, 22, 23, 23. ing. Note that the coupling portion 13 is omitted in this example.

"Effects of the Invention" As described above, in the present invention, the knob member 3 is provided as an independent member in a pivotal manner on the front edge of the opening/closing plate 2, and is normally stored in a hanging state in the storage groove 7 on the front surface of the cap body 1 and protrudes from the front surface. This eliminates the inconvenience of opening the lid by pulling the grip member 3 on something, making it safe and suitable for use as a portable container. Moreover, when opening and closing the lid, it is only necessary to raise and lower the knob member 3, and there is no trouble at all.
