Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a lid with an opening device, which is mainly mounted on a beverage / food container for use.

[Prior art and its problems] Recently, a lot of packaging forms have been sold in which juice and liquor are stored in a cup-shaped container, the canopy is opened, and then the mouth of the container is directly put into the mouth to drink. ing. For example,
A can container containing juice, etc. forms an open area defined by score lines on the panel that constitutes the canopy, and a pull tab is attached to this open area.When opening, the pull tab is raised to open the open area along the score line. There are those that are cut open, and those that are obtained by directly affixing a sealing material directly to the opening of the container and sealing it, and then peeling the sealing material to expose the container opening when opening.

However, in these conventional products, the strength of the panel base material and the adhesive strength of the sealing material are weakened when they are easily opened, so it is difficult to achieve a balance between the strength required as a packaging container for beverages and foods and the ease of opening. is there. Also, something like this
After opening, the remaining part of the canopy appeared like a flange, so there were some inconveniences such as cutting the mouth with the flange when drinking and the contents were hard to come out.

On the other hand, there is a container intended to open and open the entire canopy using a special cutter as seen in a storage container such as seaweed. However, this one has a drawback that the canopy cut off when the entire canopy is cut down falls into the container and is difficult to use as a beverage container.

[Means for Solving Problems] The present invention has been made in view of the problems of the conventional type as described above, and an object of the present invention is to attach a lid to be used by being attached to an opening of a beverage / food container. That is, a cutter blade is built in the inside thereof, and the cutter blade has a movable structure, and at the time of opening, the whole cutter member is moved to the inside of the opening of the container to cover the opening of the container. In addition to making it easy to cut off, the sealing member that has been cut off does not fall into the container at all, and further, when not in use except when opening, move the cutter blade to the outside of the container opening. The present invention is intended to provide a novel lid with an opening device in which the cutter blade and the blocking member do not come into contact with each other, and is characterized by having the following configuration.

That is, the present invention is a lid formed so as to cover an outer side of a circular opening of a cylindrical container so as to be rotatable, and an inner wall is projected downward on an inner side of an outer wall of the lid, and an inner circumference of the inner wall is formed. Is formed with a holding piece extending in the circumferential direction, and at least one hole extending over the top plate portion of the lid and the inner and outer walls is provided to form a lid main body, and a movable bracket capable of closing the lid is engaged in the hole. A cutter that is movably mounted in the diameter direction of the lid via a coupling means, and is cut below by opening the sealing member at the circular opening of the container below the holding piece and at a part of the lower portion of the movable bracket. It is a lid with an opening device, which is provided with a blade and a claw piece that guides the closing member obliquely upward in the rotational direction.

[Operation] Since the present invention is configured as described above, the circular shape of the cylindrical container is retained when the cutter blade at the tip of the movable bracket is housed and held in the hole provided in the outer wall of the lid when not in use except when opening. It is fitted in the opening. When opening, remove the lid from the opening of the container, move the cutter blade toward the center of the lid with the movable bracket, and then press this lid against the closing member of the circular opening of the cylindrical container and rotate it, Cut into a circular shape by cutting into the blocking member. At that time, the claw piece provided on the inner surface of the lower part of the movable bracket works to flip up the closing member separated by the cutter blade, and the holding piece provided on the inner circumference of the inner wall of the lid body puts the closing member inside the container. Hold so that it does not fall.

[Embodiment] Next, an embodiment of the present invention will be specifically described with reference to the drawings.

FIG. 1 is an exploded perspective view showing the structure of a lid 10 with an opening device according to the present invention, and FIG. 2 is an unopened cylindrical container with the lid attached.
FIG. 3 is a perspective view showing the outer appearance of 20, and FIG. 3 is a sectional view of an essential part in a state similar to FIG.

As shown in FIG. 2, the lid 10 is used, for example, by attaching the body portion to the top portion of the cylindrical container 20 formed of paper, plastic, metal, or a composite material in which these are combined. The top of the cylindrical container is a circular opening that is recessed inward as shown in Fig. 3.
The opening 21 is sealed with a sealing member (membrane) 22 formed of easily cut paper, metal foil, plastic film or the like.

By the way, the lid 10 according to the present invention may be formed of a molded product made of a plastic material such as acrylic, polycarbonate, polypropylene, or a metal material. The lid 10 is composed of a lid body 1 having an opening 5 extending across the top plate 2 and the outer wall 3 with a ridge line in between, and a movable bracket 6 detachably attached to the opening. The movable bracket 6 is attached so as to be movable in the diametrical direction of the lid main body 1 through the engaging means when it is used, so that the opening 5 can be closed normally.

The detailed configuration of the lid body 1 will be described below with reference to FIGS. 1 and 3 to 4. An inner wall 4 having a substantially annular shape is provided on the back surface of the circular top plate portion 2 so as to project downward. The downward projection length of the inner wall 4 is kept slightly smaller than the height from the top of the circular opening 21 of the cylindrical container to the surface of the sealing member 22 recessed inward. A fitting groove 7 into which the circular opening 21 of the tubular container 20 can be fitted is formed between the inner wall 4 and the outer wall 3. The width of this fitting groove is formed to such an extent that the lid body 1 fitted in the circular opening 21 can be rotatably rotated. In the present invention, a holding piece 8 having a horizontal plane extending in the circumferential direction is provided on the inner circumference of the lower portion of the annular inner wall 4. This holding piece has a function of holding the blocking member cut off by the cutter blade in the lid so as not to fall down. Although the holding piece is continuous in the circumferential direction in the illustrated example, it may be formed intermittently. As described above, the top plate 2 and the outer wall 3 are provided on a part of the lid body.
An opening 5 is provided that spans the inner wall 4 and partially cuts the inner wall 4 to accommodate the movable bracket 6. The movable bracket 6 is provided on the inner periphery of the opening 5 located on the top plate side.
A hooking projection 9 for engaging and holding

On the other hand, the movable bracket 6 is formed to have a shape and size corresponding to the opening 5 of the lid body 1 so that the opening of the lid body can be normally closed as shown in FIGS. I am configuring. The lower part of this movable bracket has a fifth
As shown in the figure, a cutter blade 11 is provided for cutting open the sealing member 22 having a circular opening in the container. The cutter blade is provided in a downward or obliquely downward position at a position where the sealing member 22 can be easily cut when opening. Further, on the inner surface side of the lower portion of the movable bracket, there is provided a claw piece 12 having an inclined surface for guiding the cut-off blocking member 22 obliquely upward in the rotation direction. When the movable bracket 6 is attached to the lid body 1, this inclined surface is formed so as to extend below the holding piece 8 and obliquely downward toward the cutting edge of the cutter blade 11.
Incidentally, reference numeral 13 is an engaging groove formed in a part of the peripheral edge of the movable bracket 6 corresponding to the hooking projection 9 provided on the inner circumference of the opening.

In order to cover the container sealing member 22 with the lid of the present invention configured as described above, once the lid is removed from the circular opening of the container, the movable bracket 6 is moved toward the center of the lid body 1. Moving. After that, the lid body 1 is again attached to the circular opening of the cylindrical container, and the cutter blade 11 is pressed against the sealing member 22 and then rotated, and the cutter blade 11 bites into the sealing member 22 as shown in FIGS. Cut into circles. At that time, the claw piece 12 provided at the tip of the movable bracket works to flip up the peripheral edge portion of the sealing member 22 separated by the cutter blade 11 as shown in FIG. 8, and the holding piece provided on the inner wall 4 of the lid body. The piece 8 holds the separated sealing member 22 so as not to drop into the container opening 21. Then, when the lid 10 is released, the entire top of the container 20 is opened as shown in FIG. The illustrated embodiment shows an example in which one opening 6 is provided in the lid main body 1 and one movable bracket having a cutter blade 11 is inserted therein. However, for example, several holes may be formed at intervals in the circumferential direction of the lid body, and the movable brackets may be respectively engaged with these holes. In particular, when two movable brackets are arranged on the diameter line of the lid main body, the whole area of the circular opening can be opened only by rotating the device of the present invention half a turn (not shown).

The lid body and the movable bracket are usually made of the same kind of material, but they can be made of different materials. For example, when the lid main body is made of a relatively soft polyethylene resin or the like, the movable bracket may be made of a harder material. It is also possible to separately form only the cutter blade of steel or the like and attach it to the movable bracket.

[Effects of the Invention] As described above, according to the present invention, the cutter blade is moved to the outside of the container opening through the movable bracket so as to be housed and held in the hole provided on the outer wall of the lid during handling other than opening. Therefore, it is possible to prevent the blade edge 12 of the cutter from accidentally coming into contact with the sealing member of the container and breaking it to leak the contents. When the cutter blade is moved to the inside of the circular opening of the container through the movable bracket when opening, and then pushed down and rotated toward the closing member of the opening, the cutter blade bites into the closing member and the opening of the container is opened. It is possible to open the whole area of the member that covers the cover very easily, and hold the inside of the lid so that the blocking member that is cut off during the opening is turned up and does not drop into the container. can do.
