Description

The present invention relates to a hinge cap with a separation function that can be easily separated at the time of separating and collecting garbage. More specifically, the conventional cap with a separation function makes it easy to break. Therefore, the problem that the sealing structure of the container main body and the cap main body is loosely formed is solved, excellent sealing performance is maintained during use, and the broken portion of the cap main body can be easily separated at the time of sorting and disposal. It is related with the hinge cap with a classification function comprised in the.

As for the hinge cap, the cap body and the upper lid are connected by a hinge, and in addition to its openability, it is also easy to open, improving convenience, so salad oil, seasonings,
It is often used in containers that contain liquid contents such as natural fruit juice. In other words, the hinge cap is made liquid-tight by plugging the cap body into the container mouth, and is kept in a liquid-tight state so that it cannot be easily removed. Easy opening of the planned part is realized.

Conventionally, such a hinge cap is often used by being attached to the mouth of a container such as a glass bottle or a plastic bottle. However, due to the difference in material between these containers and the hinge cap, it is necessary to remove the hinge cap from the container when separating and collecting garbage, and conventionally, means such as separating them using pliers or knives have been used. Since it is adopted, there is a troublesome work, and the following is known as a technique that can easily remove the hinge cap from the container.

As shown in FIGS. 5 and 6, the hinge cap disclosed in Japanese Patent Laid-Open No. 2001-192053 is formed by connecting a cap main body 52 and an upper lid 53 to a mouth portion 51 of a container 50 by a hinge 54. A deep groove 58 is formed from the portion corresponding to the root of the hinge 54 of the outer peripheral wall 55 of the main body 52 so that the radial direction reaches the outer peripheral edge of the fixed cylinder 56 and the axial direction extends above the fitting protrusion 57. A main heel weakening line 60 and a first sub heel weakening line 61 are formed from both corners 59 of the intersection with each other, and a thin portion 62 is formed between the lower end surface of the deep groove 58 and the inner surface of the outer peripheral wall 55. The main rod weakening line 60 is cut and formed in an acute angle shape from the inside to the lower end of the outer peripheral wall 55, and the first auxiliary weakening line 61 is sharpened from the inside to the lower end of the fitting rib 57. Cut in, change direction, Along the fitting projection 57 lower end as the direction lines of weakness 63 is obtained by forming progressed cut from the inside in the circumferential direction.

According to the hinge cap of Patent Document 1, when the upper lid 53 is grasped and pulled outward, the stress concentrates on both corners 59, and the main heel weakening line 60 and the first auxiliary heel weakening line 61 are torn from the upper end.
When pulled further outward, the stress concentrates on the thin portion 62 and the thin portion 62 starts to break, and the hinge 54 is separated from the cap body 52. When the upper lid 53 is pulled further outward, the circumferential weakening line 63 is torn, and the hinge cap can be detached from the mouth 51 of the container 50 by pulling diagonally upward.

The hinge cap of the above-mentioned Patent Document 1 can be used without using tools such as pliers and knives.
It can be conveniently separated from the mouth 51 of the container 50. However, this hinge cap
In order to detach from the mouth portion 51 of the container 50, a deep groove 58 is formed, a thin wall portion 62 is formed between the lower end surface of the deep groove 58 and the inner surface of the outer peripheral wall 55, and the main shaft is weakened on both sides of the deep groove 58. A line 60 and a first auxiliary weakening line 61 are formed respectively. For this reason, when the cap main body 52 is plugged into the container mouth portion 51, there is a possibility that the liquid tightness may come loose, and depending on the properties of the liquid contents contained in the container 50, the internal pressure may increase, resulting in liquid leakage. The possibility of cannot be denied.

Accordingly, an object of the present invention is to enable separation to ensure sufficient liquid tightness without being affected by the properties of the liquid contents, while being easily separable from the container mouth without using a tool. It is to provide a hinge cap with a function.

Therefore, in addition to the above effects, an effect that can be maintained even cleanliness appearance.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

FIG. 1 is a longitudinal sectional view showing a state in which a separation function hinge cap according to an embodiment of the present invention is plugged into the mouth of a container, and FIG. 2 is a state in which the separation function hinge cap of FIG. 1 is viewed from the hinge side. FIG. 3 is a side view, FIG. 3 is a longitudinal sectional view showing a state in which the hinge cap with the same sorting function is opened, and FIG. 4 is a plan view showing a state in which the hinge cap with the same sorting function is opened. In the drawing, a separation function hinge cap 1 has a cap body 2 and an upper lid 3 connected to each other via a hinge 4 so as to be freely opened and closed. The cap body 2 includes a top plate 6 on which a planned opening portion 5 is formed. The skirt wall 7 hangs down from the peripheral edge of the top plate 6, and the skirt wall 7 and the inner ring 8 that hangs concentrically from the lower surface of the top plate 6 are fitted into the skirt wall 7. A pour cylinder 12 that forms a joint portion 11 and surrounds the planned opening portion 5 on the top surface of the top plate 6 and an outer wall 13 that closes and fixes the upper lid 3 outside.
The upper lid 3 is composed of a top plate 14 and a side wall 15 that hangs down from the peripheral edge of the top plate 14, and is an annular ring that hangs down on the inner surface of the top plate 14 and presses against the inner surface of the dispensing cylinder 12. 16 is formed.

The separation function hinge cap 1 is formed with a longitudinal weakening portion 17 that can be broken in the longitudinal direction from the upper end to the lower end of the skirt wall 7 at a location close to the hinge 4 of the skirt wall 7. As shown in FIG. 1, a circumferential weakening portion 18 that extends in the circumferential direction along the outer peripheral root of the outer wall 13 and can separate the skirt wall 7 and the top plate 6 is provided at the peripheral edge portion. And at least a position beyond the hinge 4 toward the hinge 4 side, and
An outer ring 19 that hangs down from the bottom surface of the top plate 6 is provided at a position where the outer periphery of the mouth 10 of the container 9 abuts on the outside of the inner ring 8 on the bottom surface of the top plate 6 and inside the circumferential weakening portion 18. It will be.

The container 9 to which the separation function hinge cap 1 is attached has a cap body 2 in its mouth 10.
As long as it can be plugged, there is no particular limitation, and any type and material may be used. In the first embodiment, an example of a plastic bottle that is opened and closed by the upper lid 3 in a relatively large amount is used, particularly for edible oils that are frequently dispensed.

As described above, since the upper lid 3 is connected to the cap body 2 via the hinge 4, the upper lid 3 is rotatable about the hinge 4 and can be opened and closed. Since the outer wall 13 is provided on the top plate 6 on the outer side of the dispensing tube 12 as described above,
In the unlikely event that there is liquid dripping from the dispensing cylinder 12, it will not spill out of the outer wall 13 immediately. Further, a part of the dispensing cylinder 12 on the side opposite to the hinge 4 is a beak-shaped portion 12a as can be seen from FIG. This beak-shaped portion 12a is provided in order to improve the pouring property when the liquid content is poured out. The upper lid 3 is provided with a spout correction rib 20 that urges the beak-shaped portion 12a when the cap is closed. Since the beak shape rib 12a is undercut when the spout correction rib 20 is molded, the tip of the beak shape 12a is deformed upward at the time of mold release. Therefore, the beak-shaped portion 1 deformed by the spout correction rib 20 by closing the upper lid 3 immediately after the hinge cap 1 is released from the mold.
2a can be returned to a normal shape.

Further, the opening-scheduled portion 5 inside the dispensing tube 12 is surrounded by the score 21 and is a part that can be removed by breakage. The score tearing tab 22 provided on the scheduled opening portion 5 is hooked with a finger upward. When pulled, the score 21 is broken, and the planned opening portion 5 can be removed, that is, the opening can be performed.
In FIG. 1 and FIG. 3, 22a is a slip stopper when a finger is put on the score tearing tab 22. On the other hand, the main seal after opening is performed by fitting the annular ring 16 of the upper lid 3 to the dispensing cylinder 12 of the cap body 2. That is, the outer peripheral surface 16a of the tip of the annular ring 16
Is brought into contact with the lower part of the inner peripheral surface of the dispensing cylinder 12, whereby a seal after opening is made.

The cap body 2 has a fitting portion 11 formed by the inner ring 8 and the skirt wall 7 on the lower surface of the top plate 6, and the fitting portion 11 is plugged into the mouth portion 10 of the container 9. Then, the cap body 2 is attached to the mouth portion 10 and liquid-tight.

On the other hand, as described above, the longitudinal weakened portion 17 is formed in the skirt wall 7 of the cap body 2 near the hinge 4, and the longitudinal weakened portion 17 is formed on the inner side of the skirt wall 7 with the V Character-shaped grooves are formed in the vertical direction from the upper end to the lower end of the skirt wall 7.
Accordingly, when the externally weakened portion 17 grips the upper lid 3 and applies an external force such as pulling downward with the longitudinally weakened portion 17 as the center, the stress is concentrated on the upper end of the V-shaped groove and directed toward the lower end. The groove is torn, and the skirt wall 7 can be separated by breaking from the upper end to the lower end in the vertical direction. Further, the skirt wall 7 cannot be seen from the outside, and dust does not collect in the V-shaped groove, and the appearance is very good. It becomes.

Further, as described above, the peripheral portion of the top plate 6, which is a joint portion between the skirt wall 7 and the top plate 6,
A circumferential weakened portion 18 is provided. The circumferential weakened portion 18 is formed on the lower surface, which is the inner side of the peripheral edge of the top plate 6, with a U-shaped groove in the circumferential direction and the longitudinal weakened portion 17 as a starting point on the hinge 4 side. It is provided up to a position beyond the opposite hinge 4. Therefore, after the skirt wall 7 is broken in the longitudinal direction, the circumferential weakened portion 18 further holds the upper lid 3 and then the longitudinal weakened portion 17 that is the starting point of the circumferential weakened portion 18. When applying external force such as pulling along
The stress concentrates on the starting point of the U-shaped groove, and the U-shaped groove tears toward the position beyond the hinge 4,
The skirt wall 7 and the top plate 6 can be separated up to that position. Further, the skirt wall 7 and the top plate 6 cannot be seen from the outside, dust and the like do not accumulate in the U-shaped groove, and the appearance is very good.

As described above, the outer ring 19 is provided on the lower surface of the top plate 6 of the cap body 2, and the outer ring 19 is positioned between the skirt wall 7 and the inner ring 8 in the fitting portion 11. The top plate 6 is provided on the lower surface of the top plate 6 so as to be inward of the circumferential weakened portion 18 and concentrically with the skirt wall 7 and the inner ring 8 . As shown in FIGS. 1 and 4, a plurality of ribs 24 extending in the axial direction are provided at positions corresponding to portions where the circumferentially weakened portion 18 is formed at least on the inner surface of the side wall 15 of the upper lid 3. The rib 24 is in contact with the upper end of the outer wall.
Accordingly, when the outer ring 19 is fitted with the fitting portion 11 of the cap body 2 in the mouth portion 10 of the container 9, the outer periphery 10 a extending in the vertical direction of the container mouth portion 10 becomes the longitudinal weakening portion 17 and the circumferential direction. Liquid contact is achieved by abutting against the inner peripheral surface of the outer ring 19 located inside the weakening portion 18. That is, the outer ring 19 is in contact with the outer periphery 10a of the front end 10a of the container mouth 10 and realizes liquid-tightness, regardless of the portion that is weak in strength and difficult to liquid-tight.

As described above, the upper lid 3 is constituted by the top plate 14 and the side wall 15, and the top plate 14 is formed with the annular ring 16 concentrically with the side wall 15, and one end of the side wall 15 is hinged by the hinge 4. 2 openably connected to a flange 23 is provided at the other end.

Next, the usage method of the hinge cap 1 with a classification function which becomes the said structure is demonstrated.
First, the hinge cap 1 with a separation function in a state in which the upper lid 3 is fitted to the cap body 2 is filled, and the liquid content such as edible oil is filled in the container 2, and then the hinge cap with a separation function in the mouth portion 10 of the container 9. The container 9 is sealed by plugging the fitting portion 11 of 1 (see FIG. 1).
. At that time, the outer ring 19 that avoids the strength influence by the longitudinal direction weakening portion 17 and the circumferential direction weakening portion 18 is brought into contact with the outer periphery 10 a of the tip of the container mouth portion 10 to realize liquid tightness. Then, if necessary, the container 2 with the hinge cap 1 with a sorting function is packaged to obtain a final product.

When the final product is consumed, if there is any packaging, it is removed, and at least the part of the hinge cap 1 with a separation function is exposed, so that the upper lid 3 can be opened from the cap body 2, and the collar 23
The upper lid 3 can be easily opened from the cap body 2 by pushing up with a finger. Further, if the finger is put on the score tearing tab 22 and pulled, the score 21 is broken and the opening scheduled portion 5 is broken.
Can be removed and opened. Then, the required amount of liquid content in the container 9 can be poured from the dispensing tube 12 of the cap body 2 into the required location. After pouring the liquid content, when the cap body 2 is covered with the upper lid 3, the tip outer peripheral surface 16a of the annular ring 16 comes into contact with the lower part of the inner peripheral surface of the dispensing cylinder 12, and thus the seal after opening is made. The Thereafter, the same operation as described above is repeated until the liquid content in the container 9 is used up.

All the liquid contents in the container 9 are discharged, and the upper lid 3 is opened from the cap body 2,
When the upper lid 3 is grasped and pulled downward about the longitudinally weakened portion 17, stress concentrates on the upper end of the longitudinally weakened portion 17, and the longitudinally weakened portion 17 tears toward the lower end, and the skirt wall 7 of the cap body 2. , And further pulling along the circumferential weakened portion 18 from the longitudinal weakened portion 17 that is the starting point of the circumferential weakened portion 18 while holding the upper lid 3, the stress concentrates on the starting point and exceeds the hinge 4. The circumferentially weakened portion 18 is torn toward the surface, and the skirt wall 7 and the top plate 6 can be separated up to that position, and the hinge cap 1 with a separation function can be easily removed from the mouth portion 10 of the container 9, so that Can contribute to the separate collection.

As mentioned above, although Example 1 of this invention was demonstrated, a specific structure is not limited to this, It is applicable even if the inside of a container is a pressurized state, The change in the range which does not deviate from the summary of this invention It should be understood that is possible as appropriate.
