Description

Detailed Description of the Invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for packing beverages in cans.

[0002] pulled back strip from preformed portion formed on top of the background can of the invention, in the initial state is positioned flat on the upper surface of the can, to pull the fixed ring by a pin to the rear end of the strip Beverage cans, which allow the beverage in the can to be drunk through a hole opened by, are widely known.

A significant drawback of this type of can is that its top wall is vulnerable to dust contamination that accumulates during storage and transportation. Further, once opened, there is no means to close the can again, so there is a risk of spilling the contents left after the first drinking, and in any case, deterioration of the contents is unavoidable.

In a prior patent application, the inventor proposed a lid adapted to be attached to a can containing a beverage by applying a pressing force. The inner shape and size of the lid corresponds to the outer shape and size of the top end of the can. The lower surface of the lid is provided with a raised portion having a shape and size corresponding to the shape and size of the hole opened in the can when opened. After opening the lid,
Repositioned at the proper radial position, the ridge can be pushed into the hole, and the ridge acts as a stopper and hermetically seals the can so that an accidental spill of the contents. You can avoid it, and you can remove the lid each time you want to drink the contents.

The lid has an inner annular sealing rib at the top of its frustoconical lid body that matches the top of the can, creating an airtight chamber at the top.

On the outside of the lid, a handle is provided at the end of the frusto-conical lid body, and in a state of non-use, facing the top edge of the lid and closely attached to the lid body. The handle can be easily pivoted outwards to provide a pulling action on the lid to facilitate separation from the can.

As described in the above-mentioned patent application, this lid allows the contents of the can to be returned to the top of the can after each drink, thus protecting the remaining contents from contamination and preserving the flavor. can do.

[0008] An object of the present invention is an improvement over the lid of the above patent, the lid being preformed portion formed at an edge at which a handle (rim), in order to remove the lid To provide a lid characterized in that when the handle is pulled, the preformed portion causes a tearing portion on the side portion of the lid to indicate that the lid has been removed. This handle has an opening between the two side arms that allows the insertion of at least one finger of the hand, or a continuous (no opening) with ribs for finger engagement. It will consist of walls.

In one embodiment of the invention, at the lateral end of the handle of the lid, or at the end of each arm of the handle, substantially from the lower edge (rim) of the lid to that edge. A preformed linear cutoff portion extending at a right angle to the vicinity of the top edge of the lid is formed, and the linear cutoff portion is torn when the handle is pulled to remove the lid from the can.

In another embodiment of the present invention, a preformed linear arc line of a cut extending parallel to the edge is formed at a position slightly above the edge of the lid, and the linear arc line of the cut is formed. , Extended at a right angle from the edge of the lid at one side edge of the handle,
A straight line that is preformed so that it can be torn also extends from the upper end toward the other end of the handle and extends beyond the other end. Therefore, in order to remove the lid, the handle may be pulled to separate along the preformed separation line (the arc line and the straight line). The preformed separation line may be replaced by a preformed strip having a width of 22 mm or less (dimension less than or equal to 22 mm).

The diameter of the upper end of the lid, that is, the portion corresponding to the upper end of the inner annular rib is 2
． The range is 5 to 25 cm.

The above advantages of the present invention over the protective lid for canned beverages are clear. After initial opening, the lid is returned to the can and replaced to protect the remaining contents from contamination of the surrounding environment, or to preserve the flavor and orientation of the contents, and the first removal The preformed part on the side of the can that was preformed for
It clearly shows that the lid has been removed. Therefore, even if the can is opened improperly and the contents are consumed, and then the lid is replaced and reattached, it cannot be hidden that the can has been opened.

Even if the handle is pulled without noticing the broken portion and thus without noticing that the connecting portion between the handle and the lid is extended, the fact that the lid has already been removed is You can feel it.

The above objects and advantages and other features of the present invention will become more apparent from the description of the embodiments of the present invention described below with reference to the accompanying drawings.

Description of Embodiments of the Invention The can 50 itself shown in FIGS . 10 and 11 is of the type well known in the prior art and includes a body 54.
With a detachable strip 57. The side wall 56 of the protective lid 55 of the present invention, which is mounted by pressing, has two arms 62 connected to the lower edge of the lid 55, and is formed with a handle 60 having an opening 61 defined by the arms. There is.

The lid 55 extends from both side ends (both corners) of each arm at the connecting portion between the lower edge of the lid and each arm 62 of the handle to a position near the top edge of the lid at right angles to the edge. The preformed separation lines 64 and 65 are formed.

To remove the lid, disconnect the strip 57, and drink the contents, pinch the handle 60 with the fingers 58 of the hand and pull outward, along the preformed separation lines 64, 65 described above in FIG. The wall of lid 55 is ruptured as indicated at 66.

The tearing portions 66 do not weaken the strength of the handle, and even if the lid is returned to the can and reattached for later consumption of the contents remaining in the can, the lid is removed. It becomes a means to display that.

12 and 13 show a lid 75 according to a first variant of the lid 55 of the invention shown in FIGS. 10 and 11. The lid 75 of this modified example has a preformed cutaway which extends from the lower edge of the lid at right angles to the edge to just before the upper edge of the lid at two lateral ends of a handle 80 having an opening 81 and an arm 82. It is characterized by having a line 87.

To remove the lid 75, the handle 80 is grasped and pulled, cut along the preformed tear line 87 described above, and then torn as shown at 86 in FIG.

14 and 15 show a lid 95 according to a second variant of the invention. The lid 95 of this variation includes a short straight preformed separation line 107 extending at a right angle from the bottom edge of the lid at one lateral end of the handle 100 having an opening 101 and an arm 102, and slightly separated from the edge of the lid. By the way, a preformed separation parallel arc line 108 extending from the upper end of the preformed separation line 107 parallel to the lower edge of the lid toward the other side end of the handle and extending beyond the other side end of the handle is formed. It is characterized by having.

When the handle 100 is pulled by the finger 58, the above-described preformed separation line 107 is formed.
And 108, tears occur, as shown at 104 and 105 in FIG. 15, allowing the lid 95 to be removed from the can.

FIG. 16 shows a lid 115 of a third variant of the lid 95 of FIGS. 14 and 15. In this modified example, the handle 120 is substantially the same as the handle 100 described above, but is formed of a continuous wall having no opening, and a vertical rib 127 for finger engagement is formed on the wall.

As in the example of FIGS. 14 and 15, a straight preformed disconnect line 122 extending from the base at one end of the handle 120 and a preformed disconnect arc line 125 connected to the upper end of the line pulls the handle 120. This results in tears 124 and 126 along their lines that are separated, and then the lid 115 can be opened by pressing the handle 120.

Also in this modified example, the tearing portions 124 and 126 formed on the lid facilitate the use of the handle and restore the contents remaining after opening so that they can be drunk later. Also, it functions as a means to display that the can has already been opened.

Of course, instead of the preformed separation line, a preformed strip for the same purpose may be used. In that case, the width of the strip is preferably 1 to 22 mm.
