Field of the Invention [0001] The present invention relates to a silicone lid capable of temporarily holding an agar of a water cup, food, or the like, or allowing airtightness to be maintained in a state of covering or sealing the container, It is possible to make it possible to temporarily cover and keep it confidential.
For this purpose, the silicone packing is formed so as to surround the entire circumference of the circular frame body having a constant rim surface, thereby solving the unsanitary problem of adhesion and providing convenience of use.

Description

Technical Field [0001] The present invention relates to a sealing cap for sealing a container,

The present invention can temporarily cover an agar of a container that can hold a water cup or food, or a silicone cap which can temporarily hold the container or allow airtightness to be maintained by a simple operation, In particular, it is possible to use the silicone to seal the container while allowing the container to be temporarily closed, but also to allow the container to be used at the same time by a minute change in the size of the agar of the container.

Currently, most lids of food containers are injection-molded into plastic for airtightness, and most of them are made in rectangular, square, or circular shapes depending on the shape of the container.

Further, a plurality of folding locking means are provided at a predetermined interval in the rim of the lid, and a packing is mounted inside the rim of the lid.

Further, when the packing is combined with the container, the packing is locked by the locking means to press the packing so that the contents contained in the container are prevented from being leaked.

However, such folding locking blades protrude from the rim of the lid, resulting in inconvenience in use due to interference of protruding locking blades between such containers in a narrow refrigerator or the like filled with a plurality of containers, And therefore, there is a problem in that it can not be easily opened or locked when compressed.

In addition, since it is difficult to tightly assemble the lid with the lid due to the use of the lid and the foreign matter is caught between the lid packed with the lid, there is a problem that the lid is not cleaned. There is a difficulty in other assembly in close assembly.

Therefore, in recent years, it has been proposed to solve the conventional problems by not using a separate locking means.

As shown in FIG. 6, by using the silicone packing having the tightening vane so as to be detachable from the rim of the lid, the tightening vane is tightly attached to the outer wall of the container body in a state of covering the container, It is proposed that there is no protrusion of the lock wing.

That is, in order to mount the silicone packing, the lid is made of the lid body and the silicone packing, and the rim of the lid body is horizontally expanded so that the mounting of the silicone packing is facilitated. Due to the rim of the lid body, It is possible to store the contents and to use the tight fitting wings of the silicone packing.

However, the disadvantage of such a disadvantage is that the central portion of the lid protrudes upward, so that it can be used only as a lid for maintaining the hermeticity of the food container, and it is difficult to stack the lid in multiple stages. Especially, In order to engage the silicone packing provided on the outer side of the lid with the rim of the lid, a groove having a predetermined rim surface must be provided. In order that the lid is elastically operated, the lid is formed to have a predetermined angle of inclination It is inconvenient to be inserted into the rim of the silicone packing at the outer edge of the lid body, and it is difficult to clean the silicone packing when the foreign matter is caught in the hinge of the silicone packing.

Therefore, in order to solve the difficulty of the detachment and to provide a variety of use as well as ease of use, a silicone cover surface is formed at the central portion of the hollow of the frame body having a constant rim surface, And the silicone packing is integrally adhered to the frame so that the elastic blades are extended to the outside of the frame.

However, the problem of such a product is that the frame is injection-molded into plastic and the packing uses silicone which is releasable in material, so that the general bonding is not possible.

Therefore, in general, in order to make such a bonding, the adhesive is attempted in a state where the surface to be adhered is molten with a toxic primer, so that there is a considerable risk when the adhesive is used as a cover of food by the toxic primer It can exist.

Therefore, when these materials are used for covering a conventional container, there is a possibility of inconvenience of use because the frame body is adhered to the silicone packing and the silicone packing is directed toward the container.

Accordingly, it is an object of the present invention to provide a silicone cap which is not only versatile but also convenient for use in a versatile manner, and can be kept air-tight when applied to a closed container, regardless of the minute size of the container.

For forming the silicon packing, a silicone body having a circular or polygonal frame body having a frame face of a predetermined area and a silicone body covering the entire frame body is formed.

In addition, when the polygon is implemented, it can be applied to the polygonal lid by extending the close blades downward at the corners of the polygon.

In addition, the method of wrapping the entire frame is used for manufacturing by using the injection molding technique.

Accordingly, when the container is covered with the upper surface and the tightening vane integrally with the wrapped portion in a state in which the silicon body is entirely wrapped around the frame body having the constant rim surface to be injection-molded by plastic, So that it can be hermetically sealed even when the size of the container is small because the entire body is entirely wrapped by harmless to the human body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 to 3, the structure of the present invention includes a frame body 10 having a certain rim surface 11 formed by injection molding with plastic, and a silicon body 10 having a horizontal surface for wrapping the rim body 10 with silicon. A portion (23) surrounding the frame body is formed on the upper side of the rim of the lid surface (22) so as to extend from the silicon lid surface and the rim portion (23) is integrally formed with the rim of the silicon lid surface And a silicone lid 20 having a tightly coupled vane 21 formed extending downwardly.
That is, the structure in which the frame body 10 is wrapped is divided into the silicon cover surface 22 and the wrapping portion 23 with the rim of the horizontal silicon cover surface 22, And the enclosing part 23 is integrally connected with the rim of the branched silicon cover surface 22 and extends downward to integrally form the tightening vane 21. [

At this time, the tightening vane 21 is formed to be inclined inwardly when it extends downward from the wrapping portion 23 so as to be resiliently operated. At this time, the vertical vanes 21- 1 is formed in a state of being inclined inwardly, it is easy to be fitted and resiliently actuated when engaged with the container body 1. [
In addition, the fastening vane 21 is formed such that a relatively long portion 21a and a relatively long portion 21b are formed so as to intersect with each other in a continuous bending manner.

As shown in FIG. 1A, in the case of a polygon, for example, when the square portion or the square portion is rectangular, the tightening blade can be made longer by extending the relatively longer portion 21b than when the long portion 21b is circular. .

The reinforcing piece 21c can be formed on both the short portion 21a and the long portion 21b forming the tightening vane 21 for reinforcing the tightening vane 21.

The reinforcing bar 21c is formed horizontally in order to improve the adhesion when the tightening vane 21 is in close contact with the container body 1. The reinforcing bar 21c is formed horizontally in order to prevent the tip of the tightening vane 21 from coming off, The reinforcing bar 21d is also formed at the tip end, so that it is possible not only to prevent lifting but also to improve the adhesion.

In this case, the silicone lid 20 forms the wrapping part 23 in the frame body 10 to be implemented by using a multi-injection molding method using a multiple injection molding machine.

However, it is needless to say that the object of the present invention can be achieved when another injector is used with the same technical idea as the multi-injection method.

The multi-injection molding machine used in the present invention is a general-purpose injection molding machine in which a general injection molding machine is divided into an injection molding machine and a vertical molding machine in which the injection cylinder leader and the mold transfer are vertically moved (vertical taye) injection machine.

The advantage of such a multi-injection machine is that the insert is stable because the mold is lying horizontally rather than vertically.

Therefore, the molding body 110 of the lower mold 100 is filled with the silicon 30 in a primary state, and the frame body 10 is placed on the upper side of the filled silicon body 30, It is possible to simply cover the frame body 10 without using any fixing means by injecting the injection silicone 40 in a state of covering the mold 200. [

However, even when a generally used injection cylinder and a horizontal type injection machine in which the mold transfer is horizontally moved are used, when the silicone packing is inserted into the injection molded frame body, the frame body is inserted into the vertically positioned mold It is needless to say that injection molding of the insert is possible if it can be fixed vertically.

In the present invention, injection molding is performed by a multi-injection molding machine in which a mold moves vertically for productivity, thereby facilitating the ease and stability of the insert.

The multi-injection machine used in the present invention is one embodiment of the present invention. In the case of using a horizontal injection machine in the state that the frame body 10 is wrapped with silicone, Of course, if the hole is not formed in the state of the audited excitation, it is possible to perform various methods.

The frame body 10 used in the present invention is injection-molded from plastic, and when it is possible to maintain the rigidity and constant strength as much as possible, the frame body 10 can have a sense of stability when airtightness is maintained as a lid.

Fig. 4 is a view showing another embodiment of the present invention. As shown in Fig. 4, the silicon cover surface 22 of the silicon lid 20, which is located at the central hollow portion of the frame body 10, It is possible to simply cover any cup of a circular or polygonal shape, and it is also possible to maintain the airtightness of the inner space of the cup just by pressing in a covered state.
