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 has the advantage that it 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.

In this invention, a locking member flush with the outer surface of the main body is pushably disposed on the lower surface of the opening/closing plate without a knob.
To obtain an elastic reversible cap which eliminates the above-mentioned inconvenience by pushing the locking member during operation, thereby forming a finger-resting space on the front lower surface of the opening/closing plate.

``Means for Solving the Problems'' The elastic reversible cap of the present invention has a thick top wall, leaving a top plate 4, and grooves 5 on both sides from the front to both sides of the top wall. A substantially C-shaped engagement groove 6 in a plan view, in which 5 is a parallel surface in the front and back direction, is recessed, engagement vertical strips 7, 7 are provided protruding from both groove surfaces 5, 5, and a groove 6 extending into the top plate 4 is provided. A cap body 1 with a hole 8 formed therein, the cap body 1 having a face-down dish shape, integrally connected to the cap body 1 at the rear side by a flexible hinge, and provided on the top surface of the cap body 1 so as to be able to open in one direction, A plug 9 to be inserted into the spout hole 8 hangs from the center of the back surface, and an engagement piece 1 projects rearward from the lower front edge of the hanging peripheral wall 10.
1, and an opening/closing plate 2 having a shape corresponding to the engaging groove 6, which is pushably engaged with the engaging groove 6, and which engages with the engaging longitudinal strips 7, 7 on both inner surfaces. The mating vertical grooves 12, 12 are recessed, and a forward-facing engagement hole 13 is formed in the upper surface for inserting the engagement piece 11 to lock the opening/closing plate 2, so that it is pushed rearward and locked when the lid is opened. The lock member 3 is configured to release the lock member 3 and to form a space on the front lower surface of the opening/closing plate 2 for placing a finger.

"Operation" In the above, the lock member 3 engaged with the engagement groove 6
is normally in a predetermined position as shown in FIG. However, in this state, the engagement hole 13 at the front of the locking member 3 is engaged with the engagement piece 11 at the front of the opening/closing plate 2.
The opening/closing plate 2 maintains a closed state. That is, it is in a locked state.

When dispensing the contents, push the locking member 3 backward to disengage the engagement hole 13 from the engagement piece 11 to release the lock, and at the same time, open the opening on the lower surface of the front of the opening/closing plate 2 for finger hooking. It is sufficient to form a hole, place a finger on the front lower surface of the opening/closing plate 2 through this hole, and open it rearward as shown in FIG. As a result, the stopper 9 comes out of the spout hole 8 and is opened.

When closing the lid, close the opening/closing plate 2 in the state shown in FIG. 2, and then return the locking member 3 to its original position on the front side. Then, the engagement piece 11 is inserted and engaged with the engagement hole 13, and the opening/closing plate 2 is locked in the state shown in FIG.

Therefore, the locking member 3 engages with the engagement vertical strips 7, 7 via the engagement longitudinal grooves 12, 12, so that the locking member 3 is stable in both the open and closed states.

``Example'' The elastic reversible cap of the present invention has a cap body 1 having a spout hole 8 at the top, a plug 9 to be inserted into the spout hole 8, 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 locking member 3 that is engaged with an engagement groove 6 on the upper part of the cover body 1 so as to be pushed backward to lock the opening/closing of the opening/closing plate 2, and is molded from a synthetic resin material. Manufactured.

The cap body 1 has a thick top wall, and on this top wall,
A substantially C-shaped engagement groove 6 in plan view is formed by cutting out the top plate 4 from the sides from the front to both sides, and in this case, the groove surfaces 5, 5 on both sides are parallel flat in the front-rear direction. A pair of engaging longitudinal strips 7, 7, 7, 7, which are spaced apart in the front and rear direction and have a half-moon cross section, protrude from the flat groove surfaces 5, 5, respectively, and the spout hole 8 is formed through the upper surface of the top plate 4. It is attached to the mouth and neck of the container body by screwing or other means.

The opening/closing plate 2 has an upside-down dish-like shape, and has a stopper 9 hanging from the center of the back surface, and an engaging piece 11 projecting rearward from the lower front edge of the hanging peripheral wall 10.

This opening/closing plate 2 has an inverted L-shaped strip-shaped separating piece 14 on the rear connecting side, and this is attached to three flexible hinges 1.
5a, 15b, and 15c 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 shown in FIG. This state can be maintained by opening the lid backwards as 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, the same can be said of a structure in which the flexible hinge is provided at one location, and a pair of legs are arranged on both sides of the flexible hinge, which are flipped back and forth when opened and closed, and maintain the state.

The lock member 3 has an engagement groove 6 in the cap body 1.
It has a substantially C-shaped shape in plan view corresponding to the shape of the engagement groove 6, but it is hollowed out somewhat deeply on the inner surface of the front side, so there is always a space between the engagement groove 6 and the front groove surface, so that it can be pushed in. It's summery. Also, each engaging vertical groove 1 on both sides of the inner surface
Reference numeral 2 denotes a concave surface having a half-moon cross section corresponding to the longitudinal strip 7, and is shaped to allow relatively smooth engagement and disengagement, and three concave surfaces are formed on each side at positions shifted back and forth. That is, in the normally closed state of FIG. 3, the two engaging vertical grooves 12 on the rear side on both sides,
12, 12, 12 engage with the engagement longitudinal grooves 7, 7, 7, 7, and when pushed in as shown in Fig. 2 during operation, the two engagement longitudinal grooves 12, 12, 12 on the front side , 12 engage with the engagement vertical strips 7, 7, 7, 7, respectively.

In reality, one engagement longitudinal strip 7 and two engagement longitudinal grooves 12 may be formed on each side, but for the sake of reliability and stability of operation, one extra set is formed in the embodiment. This locking member 3 has a peripheral portion of its upper surface cut off to form a seat 16 for receiving the hanging peripheral wall 10 of the opening/closing plate 2, and therefore, the engagement hole 13 is formed using a protrusion at the center of the upper surface. .

"Effects of the Invention" As described above, the present invention has a locking member 3 which is pushably disposed on the top wall of the cap body 1, flush with the outer surface of the main body side and located on the lower surface of the opening/closing plate 2. 3, the lock is released, and a space is formed on the bottom of the front of the opening/closing plate 2 for the finger to be placed. Therefore, the opening operation can be locked at all times, and the lid can be opened by pulling it on something. It is safe because it eliminates the inconvenience caused by locking and locking, and locking and unlocking can be done with a single touch, making the operation simple and hassle-free.
