Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a synthetic resin cap for separating and collecting formed as a stopper-type spout, and a cavity for separating the cap from the container after use so that the container and the cap can be separated and discarded. The present invention relates to a separate collection cap with a part.

2. Description of the Related Art A tapping-type spout means a synthetic resin spout firmly fixed to the mouth of a container by tapping, and a lid provided at this spout for opening and closing the container Open and close.

Since this type of stopper-type spout is made of a synthetic resin material, in order to separate and collect it from a glass container or a PET bottle, the stopper-type spout is firmly fixed to the mouth of the container. Need to be removed from the mouth.

Therefore, as a separately recoverable cap that has been developed for the purpose of separately recovering as described above, the actual cap 5-34151 is used.
There is a cap described in the publication. This cap is
A stopper is provided on the tapping spout that fits in the container, and a weakening line is formed on the upper connection part of this hinge, and a weakening line is formed along the side surface of the hinge from the upper end to the lower end of the spout side surface. It was done.

Further, as a similar application, Japanese Patent Application Laid-Open No. 8-34462
A cap that can be separately collected is disclosed in Japanese Patent Publication No. This application is a further improvement of the former cap having a weakened line. That is, in order to eliminate the risk that the weakening line is broken when the tapping-type spout is plugged into the container mouth, the portion where the weakening line is provided is covered from the outside to form a double structure. The weakening line is separated from the lower end of the hinge so that the stopper-type spout can be separated without breaking the hinge.

[0006]

As described above, the conventional separation and recovery cap has been developed so that the cap can be removed from the container mouth. How to easily remove the cap is further investigated. It remains an important issue.

The possibility of damaging the spout at the time of tapping from the weakening line has been clarified by subsequent research by eliminating the thickness and strength of the spout.
On the other hand, even after a part of the spout has been cut off from the weakening line, the work of removing the spout from the mouth of the container is still time-consuming.

That is, in all of the above-mentioned conventional techniques, the side surface of the stopper type spout is cut off along the hinge. The former is separated from the upper end of the hinge, the latter is separated from the lower end of the hinge,
The pluggable spout must be separated along the width of this hinge. Then, some side surfaces of the tapping-type spout will surely be cut off, but since the cut-off part is about the same as the width of the hinge, work to remove the tapping-type spout left at the container mouth Is still a difficult task. In particular, it is difficult for elderly people, women, etc. who are powerless to further open and remove the stopper type spout by using the slightly separated part as a clue, and remove the spout unless some kind of tool is used. There are many cases where you cannot do it.

Moreover, in order to eliminate the possibility that the spout will be damaged from the weakening line at the time of tapping, the work of removing the spout becomes more difficult as the thickness of the spout is increased or the strength of the separated portion is increased. .

On the other hand, the essential condition for the stopper type spout is that the contents should be installed so as not to leak. However, the more firmly attached the contents so that they do not leak, the more difficult it is to come off. Therefore, the separate collection cap, which separates the cap from the container after use, requires a configuration having conflicting conditions.

Therefore, the present invention was created for the purpose of facilitating the removal work of the cap for separate collection, and the contents can be installed so as not to leak, and the spout may be opened after use. An object of the present invention is to provide a separation recovery cap with a cavity that can be removed extremely easily.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

The cap of the present invention is a capping-type spout 1 that is capped on the outside of the mouth P1 of a container P, a lid 2 that covers the spout 1, and the lid 2 and the spout 1. It is a synthetic resin cap integrally provided with a hinge 3 for swingably connecting and (see FIG. 1).

The spout 1 is attached by capping the upper end of the mouth P1 of the container P (see FIG. 2). Further, a swingable hinge 3 is integrally provided on the side surface of the spout 1, and the spout 1 is covered by a lid body 2 connected to the hinge 3.

The lid 2 is swingably connected to the side surface of the spout 1 by a hinge 3. At this time, a locking portion that engages with a locking ring 9 provided around the opening of the spout 1 and a fitting protrusion (not shown) that fits inside the spout 8 are provided on the lower surface of the lid 2. The spout 8 is projected and sealed when the lid is applied.

The hinge 3 is integrally connected to the vicinity of the mouth portion P1 on the side surface of the spout 1 and the lower end portion on the side surface of the lid 2. A pair of left and right vertical weakening lines 4 extending from both ends of the hinge 3 to the vicinity of the lower end of the spout 1 are provided. Furthermore, a cavity 6 is formed inside the side wall of the spout 1 from the base of the hinge 3 of the spout 1 along the space between the longitudinal weakening lines 4 (see FIG. 4). This cavity 6 facilitates the separation of the vertical weakening line 4. Further, since the side wall portion of the spout 1 provided with the hollow portion 6 is in a state of being able to extend thinner than the other side wall portions, when spouting the spout 1 at the upper end of the mouth P1 of the container P is performed. The vertical weakening line 4 is prevented from being damaged.

A pair of weakening opening lines 7 that are wider than the width of the hinge 3 are formed on both sides of the vertical weakening line 4 in the spout 1 (see FIG. 2). This weakened opening line 7 is
It is a thin-walled product formed from the lower end of the side surface of the spout 1 to the vicinity of the upper end of the mouth P1 of the container P, and is provided on both outer sides of the vertical weakening line 4 so as to be wider than the hinge 3.
Then, the vertical weakening line 4 and the weakening opening line 7
Is provided so that the outer surface of the side wall of the spout 1 is located at the crocodile. This is because the diameter of the weakening opening line 7 is increased by the thickness of the side wall of the spout 1 and the arc length of the thin portion is larger than that when the weakening opening line 7 is provided inside the side wall of the spout 1 for example. Become. Then, since the elastic force increases by the length of the thin portion, the force easily escapes at the time of plugging.

The lateral weakening line 5 is a thin-walled portion which is provided so that the left and right side walls of the spout 1 are separated from the upper ends of the weakening opening lines 7 substantially horizontally, and the upper part of the spout 1 is opened substantially horizontally. , And is formed so as to be subsequently separated from the upper end of the weakening opening line 7 (see FIG. 3). That is, when the lid 2 is lifted so as to separate the weakening opening line 7 from the lower end, the lateral weakening line 5 is sequentially separated from the weakening opening line 7.

The pair of lateral weakening lines 5 are connected to the hinge 3
12% from the center of spout 1 at a symmetrical position centered on
The positions forming an angle of 0 ° are defined as both ends, and the ends are further formed in the range of 45 ° toward the diameter position direction of the spout 1 (see FIG. 3). By setting in this way, it is not necessary to use extra force for removal work, and the horizontal weakening line 5
After being separated, the spout 1 is on the verge of completely coming off the mouth P1 of the container P, and anyone can easily spout the spout 1
Can be removed. However, this angle is the spout 1
You may change suitably by changing the material, size, etc. of.

As described above, the vertical weakening line 4 cut off downward from the root of the hinge 3 of the spout 1 and the spout 1
Weakening opening line 7 that is separated upward from the vicinity of the lower end of the
And the lateral weakening line 5, which separates the left and right side walls of the spout 1 from the upper ends of the weakening opening lines 7 substantially horizontally, can be separated by a simple operation. That is,
The vertical weakening line 4 is cut off by grasping the lid body 2 and pulling the lid body 2 downward from the hinge 3 (see FIG. 5).
Next, the lid 2 is pulled upward from the lower end of the vertical weakening line 4 so that the lateral weakening line 5 is sequentially separated from the weakening opening line 7 (see FIG. 6). in this way,
The vertical weakening line 4, the weakening opening line 7, and the lateral weakening line 5 are cut off in this order only by operating the lid 2 up and down. In addition, even if the lid 2 is strongly pulled up without cutting the longitudinal weakening line 4 due to a reason such as speedy separation or an incorrect sorting method, the weakening opening line 7 should be cut off and removed. You can

[0026]

The present invention has achieved the original object by being configured as described above.

That is, a spouting type spout 1 is spouted on the outside of the mouth P1 of the container P, a lid 2 for covering the spout 1 and the lid 2 and the spout 1 are shaken. In a separate collection cap integrally provided with a hinge 3 that is movably connected, a pair of left and right vertical weakening lines extending from both ends of the root of the hinge 3 connected to the outer surface of the spout 1 to near the lower end of the spout 1 4 is provided, and a cavity 6 is opened from the root of the hinge 3 of the spout 1 along the mutual weakening lines 4 to the spout 1.
A pair of weakening opening lines 7 that are formed inside the side walls of the hinge and open on both outer sides of the vertical weakening line 4 to be wider than the width of the hinge 3.
Is formed from the lower end of the side surface of the spout 1 to the vicinity of the upper end of the mouth P1 of the container P, and a pair of lateral weakening lines 5 for substantially horizontally separating the left and right side walls of the spout 1 from the upper ends of the weakening opening lines 7 are formed. By providing the hollow portion 6, the vertical weakening line 4
Since it is possible to easily separate the lateral weakening line 5 from the subsequent weakening opening line 7, the spout 1 can be very easily removed after use.

Moreover, the pair of lateral weakening lines 5 are arranged symmetrically with respect to the hinge 3 from the center of the spout 1.
Since the positions that make an angle of 120 ° are both ends and the ends are further formed in the range of 45 ° toward the diameter position direction of the spout 1, the lateral weakening line 5 should be sequentially separated from the weakening opening line 7. Then, the spout 1 is largely separated up to a portion reaching the diameter position of the spout 1. Therefore, it is possible to easily remove the spout 1 after use from the mouth portion P1, and it becomes possible for even a weak elderly person or woman to easily remove it without using a tool.

The vertical weakening line 4 is separated by pulling the lid 2 downward from the hinge 3, and the lid 2 is pulled upward from the lower end of the vertical weakening line 4 to the lateral weakening line 7. Since 5 is formed so as to be sequentially separated, a series of operations for removing the spout 1 is extremely easy to understand. Moreover, the force for separating each part of the spout 1 is rationally distributed, and the force applied to the hinge part is reduced, so that it can be removed very easily.

Furthermore, the recovery cap of the present invention can be easily molded as a one-piece cap, and since no extra knob or protrusion is required to remove the spout 1, the external shape is also neat. Can be formed into a design.

Further, the vertical weakening line 4 and the weakening opening line 7 are provided on the outer surface of the side wall of the spout 1 so that the arc of the thin portion can be reduced as compared with the case where the inner surface of the side wall of the spout 1 is formed on the spar. Since the length is large, it has more elastic force than other parts, and it is easier for the force to escape when plugging. As a result, the container P mouth P
It is possible to prevent damage to the spout 1 when plugging into 1.
The spout 1 can be firmly attached so that the contents do not leak. Moreover, by providing the vertical weakening line 4 and the weakening opening line 7 on the outer surface of the side wall of the spout 1, it is possible to form a neat appearance design.

As described above, according to the present invention, the contents can be installed so as not to leak, and after use,
The effect is that the spout can be removed extremely easily.
