Description

[Detailed description of the invention] This invention consists of a synthetic resin sealing crown fitted onto a cap with an elastic hook piece that houses a synthetic resin dish-shaped stopper, and these three parts are assembled together in advance to create a comprehensive product. The present invention relates to a can opening sealing device that can complete sealing by press-fitting a lid into the can opening.

At present, a cap unit in which a simple cylindrical sealing crown made of synthetic resin is fitted onto a cap with an elastic hook and a built-in sheet-like packing is used as a well-known product.

Alternatively, first fit a simple plate-shaped stopper into the mouth of the can, then attach a cap with an elastic hook (with or without a seal) over the top, and then attach a metal or synthetic resin seal. There are also can mouth sealing devices that complete the closure by fitting a crown onto the outside.

Furthermore, we have also proposed a can opening sealing device that seals and seals a can by press-fitting a cap unit in which a cap with an elastic hook has a built-in opening means and a synthetic resin dish-shaped stopper with a sealing action into the can opening. It's being served.

However, such conventional cap units and can closure devices each have the following drawbacks.

First, a cap unit is a cap with an elastic hook and a simple cylindrical synthetic resin sealing cap.
Since there is no means for opening the seal, a tool such as a screwdriver must be used to remove the sealing cap.

In addition, the above-mentioned can opening sealing device can be used to close the stopper, cap, etc.
In the case where each sealing crown is attached separately to seal and seal, the sealing process requires multiple steps, requiring manual labor and
Alternatively, the equipment requires a great deal of expense and productivity is very low, and when used, it is difficult to remove the metal seal crown and requires tools.

Therefore, in order to compensate for these drawbacks, a device was devised in which a cap unit was fitted with a built-in synthetic resin dish-shaped stopper that was equipped with bare-handed opening means and a sealing function, and was press-fitted into the mouth of the can to seal and seal the can. The support of the whole stopper prevents the cap from denting and opening, and when the cap is removed for use, the spout is opened at the bottom of the stopper along the cut groove by pulling the handle of the dish-shaped stopper. There are some that have a means for opening and sealing within the stopper itself,
For example, when the purpose of use is to adjust the color of paint, the package may be kept sealed even after it has been opened. However, since the pillar inside the plug body is also separated at the same time, there is a risk that the cap will easily dent and open due to external loads, so it is recommended that only the above-mentioned mounting method be used. There was a problem with reuse.

The present invention is a comprehensive lid body that is preassembled into one body with three parts: a cap with an elastic hook, a dish-shaped stopper that can be inserted and removed, and a synthetic resin sealing cap that is equipped with bare-handed opening means and tamper-proofing means. They succeeded in developing a can mouth sealing device that can complete sealing and sealing with one touch by press-fitting the can into the mouth, solving the above-mentioned conventional drawbacks and having the various effects described below.

Below, an embodiment of the present invention will be explained with reference to the drawings. The cap 1 with an elastic hook (hereinafter simply referred to as the cap) made of metal material whose upper wall can be freely extended and retracted is made of synthetic resin inside the closed state. A dish-shaped stopper 2 having a flat U-shaped cross section is built-in,
A short cylindrical sealing crown 3 made of elastic synthetic resin and having an open flat bottom is fitted onto the outside of the cap.

From approximately the center of the bottom of the synthetic resin dish-shaped stopper 2, there is a hollow support 4 that protrudes upward, and this support 4.
An annular knob 5 is attached from a part of the bottom of the dish-shaped body that is the outer periphery of the
are integrally formed, and the top portion 6 of the support column 4 is made at a height such that it approaches the inside of the top surface of the cap 1, leaving a slight gap.

There is no cut groove on the bottom of the stopper, and the outer wall 7 of the stopper is smooth and gently connects to the bottom, so that the entire stopper can be pulled out from the can opening using the annular knob 5. ing.

In addition, a flange 8 protrudes from the top of the plug body, and its outer diameter is slightly larger than the inside diameter of the cap in the closed state, so that it will not fall off accidentally when it is built into the cap. Depending on the situation, a circular cushion edge 9 may also be provided to serve as a substitute for packing the cap.

Next, an arc-shaped separation groove 10 is provided near the outer periphery of the upper surface of the synthetic resin seal crown 3 that is fitted onto the outside of the cap 1, leaving the pull base 11, thereby forming an annular pull handle 12 and separating it. In the groove 10, an appropriate number of sealing bands 13, 13', which are obvious tamper-proofing means when the bag is opened, and a pull knob 14 protruding toward the center inside the annular pull handle 12 are provided.

With these configurations, the sealing crown 3 has a means for opening with bare hands and performs a sealing action.

The present invention comprises a cap 1 with an elastic hook having the above-mentioned configuration, a dish-shaped stopper 2 having an annular knob 5 that can be inserted into and removed from a can opening, an annular handle 12 and a band band 1.
3, 13' - Press-fit into the can opening 16 a comprehensive lid body made by combining the three parts of the synthetic resin seal crown 3, which is also equipped with a handle knob 14 and is equipped with bare-handed opening means and tamper prevention means. It is a can opening sealing device that can complete sealing and sealing with a single touch, and the comprehensive lid of the present invention looks like a lid that combines a well-known cap and a sealing crown, but the function when in use is Moreover, there are considerable differences in action and effects compared to conventional ones.

That is, the can opening sealing device of the present invention can complete sealing and sealing with one touch, and in order to use it, first pull the annular puller 12 with the puller knob 14 of the sealing crown, and then the inside of the separation groove 10 will be closed. The sealing bands 13, 13' were destroyed and it can be confirmed that they were opened.

If you continue to pull the annular handle with your fingertips, the sealing crown fitted onto the cap will be removed, and it can be removed with your bare hands without the need for any tools such as a screwdriver.

Next, if the center of the upper surface of the cap 1 with the elastic hook piece attached to the can mouth is strongly pressed with a fingertip, the cap will be recessed and opened. The stopper can be easily pulled out by hooking the annular knob 5 on the fingertip and pulling it.

As mentioned above, when using the present invention, the seal can be easily opened with bare hands, and the sealing cap that can be clearly seen once opened is not completely destroyed like a metal one, so it can be used again as a temporary protective ring. In addition, the dish-shaped stopper can be easily pulled out from the can opening using the annular knob, and if you wish to keep the cap sealed after opening, you can fit it back into the can opening and cover the cap. Just fit it in,
Even if some load is applied from the outside, the support inside the plug will cause the cap to collapse and open easily.

In addition, this invention combines three parts into one: a synthetic resin dish-shaped stopper, a cap with an elastic hook, and a synthetic resin sealing crown. The side and bottom surfaces of the peripheral wall have soft parts that serve as a sealing crown and a dish-shaped stopper made of synthetic resin material.

Therefore, when aligning the comprehensive lids in the same direction in an automatic sorting device, this configuration allows only the metal part of the top cap to be sensed by magnetic force, which greatly facilitates sorting between the front and back sides and reduces stirring. Even if this is done, the edges of the metal are covered with a soft material, so the metal printing on the top surface of the cap will not be damaged at all.

In addition, since the space 15 on the bottom surface of the cap is open in an annular shape, when fitting it into the can opening 16, even if it is press-fitted from directly above the can opening, the outer wall 7, which gently connects to the bottom of the stopper, serves as a guide. It is extremely easy to insert and can be installed reliably.

The conventional one has the lid pushed forward diagonally,
The method used was to hook the end of the elastic hook onto the neck of the can mouth and then push it in an arc, which led to errors in fitting.

Furthermore, in the comprehensive lid body of the present invention, the top part 6 of the pillar 4 of the stopper body is close to the inner top surface of the cap, and,
Since the sealing crown is fitted on the outside, even if pressure is applied mechanically from directly above (including press-fitting with tires, etc.), there is no sliding of the cap with the elastic hook piece causing it to dent or open, and it can be opened very smoothly and automatically. Insertion can be performed.

In conventional units that only have a cap and a plug body, the cap is supported only by the support inside the plug body, so when automatically inserted, if mechanical pressure is applied from directly above, the cap will recess and open. There was a risk of doing so.

As described above, the can opening sealing device of the present invention is an inventive device that eliminates the various drawbacks of the conventional devices, and also provides functions and effects not found in the conventional devices.
