Description

TECHNICAL FIELD The present invention relates to a sortable hinge cap that is firmly attached to a container for storing seasonings, etc., and that can be easily removed from the container when sorting.

Containers for seasonings such as soy sauce and edible oil require high sealing performance, so bottles and PET bottles are often used. In addition, a plug-type hinge cap for closing such a container is also firmly plugged into the mouth of the container. In particular, since contents such as noodle soup are hot-filled after sterilization of the bottle, a stopper-type hinged cap with extremely high sealing performance is required.

When disposing of this plug-type hinge cap separately, it is necessary to remove the tightly sealed hinge cap from the container. Therefore, conventionally, various weakening lines are provided near the base of the hinge to break the outer cylinder when the hinge is pulled. However, with hinge caps that are tightly sealed, such as those on seasoning containers, it is difficult to tear the cap off from the weakened line, and if you pull the hinge, only the hinge will tear, which could cause a so-called hinge break. there were.

Therefore, a hinge cap has been proposed that is easily separated and collected so that even a tightly sealed hinge cap can be collected to prevent the hinge from breaking (Patent Document 1). According to this hinge cap, even if the hinge cap is formed relatively thick, it can be easily torn from the weakened line by providing multiple types of weakened lines and changing the tearing direction of each weakened line. .

On the other hand, Patent Document 2 describes a synthetic resin container lid that prevents a reduction in fitting force when a hinge cap is attached to a container. Generally, when a hinge cap is tightly capped, the pressure generated during capping may cause a decrease in the fitting force of the hinge cap, but this container lid prevents a decrease in the fitting force when capping. It is possible.

In other words, since the thin deep groove provided in the fitting portion of the hinge cap is easily damaged during plugging, a seal protrusion is provided to be inserted into the thin deep groove, and the deep groove and the seal protrusion are integrated. This strengthens the fitting force in the deep groove and its vicinity during plugging.

Japanese Patent Application Publication No. 2001-192053 Patent No. 4430925

As in Patent Document 1, by providing a plurality of weakened lines and changing the tearing direction, it is possible to easily tear from the weakened lines. However, at the time of plugging, these multiple weakened lines cause a decrease in the fitting force. That is, since these weakening lines are formed by cutting out the side that contacts the mouth of the container, when the container is tightly capped, the width of the weakening lines expands, making it easy to open. In particular, this weakened line is provided near the periphery of the hinge, so if the weakened line stretches during capping, the position of the hinge will be misaligned, and the fulcrum when the top lid rotates will shift, making it impossible for the top lid to close. Sometimes it disappears.

On the other hand, in Patent Document 2, by providing a sealing protrusion to be inserted into a thin deep groove and integrating the deep groove and the sealing protrusion, it is possible to reinforce the fitting force in the deep groove and its vicinity during capping. . However, when sorting the container lid, the weakened portion is separated. Therefore, the slight weakened portion provided at the base of the seal protrusion inevitably makes it difficult to remove the container lid from the container. In particular, it is extremely difficult to separate a tightly sealed hinge cap, such as a seasoning container, with such a slight weakened portion.

Such a separable plugging type hinge cap is required to have both strength to prevent a decrease in fitting force during plugging and ease of cutting off the hinge cap for separate disposal. Therefore, the present invention was created in order to solve the above-mentioned problems.The present invention has been created to solve the above-mentioned problems. The purpose of this invention is to provide a type hinge cap.

In order to solve the above problems, a first means of the present invention includes an inner lid 1 that seals the outer periphery of the mouth P1 of the container P, and an upper lid 3 that is attached to the inner lid 1 via a hinge 2 so as to be openable and closable. In the separable plug-type hinge cap, which has a weakened line formed around the hinge 2 of the inner lid 1, the weakened line is formed by cutting out a surface of the inner lid 1 that is in contact with the container opening close to the hinge 2. The formed inner notch line 10 and the outer notch line 20 formed by notching the outer surface of the inner lid 1 are configured on the front and back through the thickness of the inner lid 1, and the inner notch line 10 The first lateral weakened line 11 is provided horizontally along the width of the hinge 2, and the slope is formed diagonally downward from the first lateral weakened line 11 toward the upper end of the outer notch line 20. The outer notch line 20 has a vertical weakened line 22 formed in the vertical direction on either or both the left and right sides of the hinge 2. It is something.

The outer notch line 20 of the second means is provided with a second lateral weakened line 21 formed horizontally from the end side of the inclined weakened line 12.

The vertical weakened line 22 of the third means includes a left vertical weakened line 22A extending vertically from the end side of the second horizontal weakened line 21 on the left side of the hinge 2, and a left vertical weakened line 22A along the vertical direction from the end side of the second horizontal weakened line 21 on the left side of the hinge 2; It is provided with a right vertical weakened line 22B extending vertically from the end side of the two horizontal weakened lines 21.

The fourth means includes a third horizontal weakened line 23 formed in the outer notch line 20 from the lower end of the right vertical weakened line 22B in the horizontal direction.

As claimed in claim 1 of the present invention, the weakened line includes an inner cutout line 10 formed by cutting out the surface of the inner lid 1 that is in contact with the container mouth near the hinge 2, and an inner cutout line 10 formed by cutting out the outer surface of the inner lid 1. The inner notch line 10 is formed on the front and back through the thickness of the inner lid 1 . Since it has a horizontal weakening line 11 and an outer notch line 20 has a vertical weakening line 22 formed in the vertical direction on either the right or left side of the hinge 2 or on both sides , at the time of capping, The width of the weakened line becomes difficult to widen, and a reduction in fitting force can be prevented when the hinge cap is firmly plugged.

That is, the inner notch line 10, which is formed approximately horizontally by cutting out the surface of the inner cover 1 in contact with the opening P1, is formed in the inner notch line 10 when the inner cover 1 extends in the circumferential direction of the opening P1 during pouring. Even if the length of the notch line 10 increases, the width of the inner notch line 10 is difficult to increase.

On the other hand, the outer notch line 20 is not in direct contact with the mouth portion P1, but is located on the outer side through the thickness of the inner lid 1. The thickness of the inner lid 1 prevents the outer notch line 20 from widening, making it difficult for the weakened line to widen during capping. In this way, the inner notch line 10 and the outer notch line 20 prevent the fitting force of the inner lid 1 from decreasing during casting.

Furthermore, since the inner notch line 10 , which is formed in a substantially horizontal direction by cutting out the surface of the inner lid 1 in contact with the opening P1, is formed in the horizontal direction near the hinge 2, The inner lid 1 can be easily separated directly from the inside. Moreover, since the ends of the inner notch line 10 and the outer notch line 20 are close to each other on the front and back through the thickness of the inner lid 1, the inner notch line 10 can be separated from the outer notch line 20. It has a continuous structure. As a result, the periphery of the hinge 2 is widely separated, so that the load is not concentrated only on the hinge 2, and the possibility of the hinge breaking is eliminated.

The inner notch line 10 also includes a first lateral weakened line 11 provided along the width of the hinge 2, and an inclined weakened line 11 formed diagonally downward from the first lateral weakened line 11 toward an outer notch line 20. line 12, when the hinge 2 is opened and the inner notch line 10 is torn apart, the load concentrated on the first lateral weakened line 11 is transferred from the first lateral weakened line 11 to the inclined weakened line 12. By being dispersed, it becomes easy to cut off the weakened line when cutting out the inner lid 1 from the inside, and it also becomes possible to cut away toward the outer notch line 20. That is, since the slope weakening line 12 transmits the force of separating the first lateral weakening line 11 to the surrounding area, the separated part of the inner lid 1 can be widened, and the separation to the outer notch line 20 can be naturally connected. be able to.

Furthermore, by configuring the first lateral weakened line 11 and the left and right inclined weakened lines 12 to form a mountain-shaped weakened line, it is possible to maintain high rigidity along these weakened lines.

As in claim 2 , the outer notch line 20 includes a second lateral weakened line 21 formed horizontally from the end side of the inclined weakened line 12, and a second lateral weakened line 21 extending from the left and right sides of the hinge 2. vertical weakened lines 22 formed in a substantially vertical direction on either or both sides, so that the load that cuts through the inner notch line 10 is applied to the second horizontal weakened line of the outer weakened line 20. 21 and the longitudinal weakening line 22, the tearing is carried over smoothly without any break.

As in claim 3 , the vertical weakened line 22 includes a left vertical weakened line 22A extending substantially perpendicularly from the end side of the second horizontal weakened line 21 on the left side of the hinge 2, and a second horizontal weakened line on the right side of the hinge 2. Since the right vertical weakened line 22B is provided along the substantially perpendicular direction from the end side of the weakened line 21, contact with the inner surface of the inner lid 1 provided with these vertical weakened lines 22, that is, the opening P1 is prevented. Since the surfaces are brought into close contact and the weakened line does not directly touch the mouth P1 as in the conventional case, the adhesion with the mouth P1 becomes higher. Furthermore, by providing the left vertical weakened line 22A and the right vertical weakened line 22B in combination around the hinge 2, it becomes easier to tear.

As in claim 4 , the outer notch line 20 is provided with the third horizontal weakened line 23 formed horizontally from the lower end of the right vertical weakened line 22B, so that the inner lid 1 can be spread over a wider area. It becomes possible to separate it.

As described above, according to the present invention, various industrially beneficial effects can be achieved, such as being able to have both strength to prevent a decrease in fitting force during plugging and ease of cutting when sorting. It is something.

(A) to (C) are diagrams showing the procedure for removing the cap of the present invention from the container.

Embodiments of the present invention will be described below. The cap of the present invention is a separable stopper-type hinge cap that is firmly plugged so that it can be used for hot filling of noodle soup or the like.

The basic structure of the cap of the present invention includes an inner lid 1 that seals the outer periphery of the mouth P1 of the container P, and an upper lid 3 that is detachably attached to the inner lid 1 via a hinge 2 (see FIG. 4). ). By forming a weakened line around the hinge 2 of the inner lid 1 , this weakened line is cut off at the time of sorting, and the inner lid 1 is removed from the mouth P1 of the container P (see FIG. 1).

The illustrated cap includes a fitting protrusion 4 around the inner peripheral surface of the inner lid 1, and an inner ring 5 that fits into the mouth P1 of the container P (see FIG. 4). Furthermore, a stopper type hinge cap is shown in which when the pull ring 6 is pulled up, the breakage portion 7 breaks and the contents are extracted from the extraction cylinder 8 (see FIG. 3). Note that this cap is not limited to the illustrated example, and the design can be freely changed as long as it has a structure of a plugging type hinge cap.

The weakened line of the present invention is composed of an inner notch line 10 and an outer notch line 20 (see FIG. 1). The inner notch line 10 is a weakened line formed by cutting out the inner surface of the inner lid 1 that is in contact with the opening P1 (see FIG. 5). On the other hand, the outer notch line 20 is formed near the hinge 2 in a substantially vertical direction (see FIG. 6). The ends of the inner notch line 10 and the outer notch line 20 are configured to overlap on the front and back through the thickness of the inner lid 1 (see FIG. 8).

The inner notch line 10 further includes a first lateral weakened line 11 and an inclined weakened line 12 (see FIG. 5). The first lateral weakening line 11 is provided along the width of the hinge 2 in the horizontal direction. The illustrated first lateral weakening line 11 is formed to have a length shorter than the lateral width of the hinge 2 so that the hinge 2 is prevented from being damaged during capping.

Furthermore, since this first lateral weakening line 11 is located at the center of the width of the hinge 2, during sorting, the force of pulling the hinge 2 with the top lid 3 is directly transmitted to the first lateral weakening line 11 (see FIG. 9). b) see). In addition, since it is formed horizontally at the highest position among the weakened lines, it is easily broken by the force of pulling the hinge 2. The first lateral weakened line 11 then cuts toward other weakened lines (see FIG. 5).

On the other hand, the inclined weakened line 12 is a weakened line formed diagonally downward from the first lateral weakened line 11 toward the outer notch line 20 (see FIG. 5). Since this inclined weakened line 12 transmits the force of separating the first lateral weakened line 11 to the surrounding area, it is possible to widen the separated part of the inner lid 1 and naturally connect the separated part to the outer notch line 20. (See Figure 8).

In addition, this inclined weakened line 12 can maintain high rigidity by configuring the first lateral weakened line 11 and the left and right inclined weakened lines 12 to form a substantially mountain-shaped weakened line (see FIG. 5). ). Therefore, even if the first horizontal weakening line 11 is formed deeply to improve tearability, it prevents stretching and deformation during capping, and eliminates the possibility that the rotational fulcrum of the hinge 2 will shift and the top lid 3 will not close. It also prevents accidental damage during use.

The outer notch line 20 further includes a second lateral weakened line 21, a vertical weakened line 22, and a third lateral weakened line 23 (see FIGS. 1 and 6).

The second lateral weakened line 21 is formed horizontally from the end side of the inner notch line 10 (see FIG. 1). The second lateral weakened line 21 in the illustrated example is at the bottom of the lateral weakened lines, and allows the tearing from the inclined weakened line 12 to continue to the vertical weakened line 22.

The vertical weakened line 22 is a weakened line formed substantially perpendicularly from the second horizontal weakened line 21 on one or both left and right sides of the hinge 2 . The illustrated vertical weakened line 22 includes a left vertical weakened line 22A and a right vertical weakened line 22B (see FIG. 7 ).

The left vertical weakened line 22A is a weakened line extending substantially vertically from the left end side of the second horizontal weakened line 21 to the left side of the hinge 2 (see FIG. 6). Further, there is a notch 24 at the upper part of the left vertical weakened line 22A, and the beginning of the left vertical weakened line 22A can be easily cut from this notch 24 (see FIG. 2). In addition, since the left vertical weakened line 22A is cut out on the outer surface side of the inner lid 1, the adhesion with the mouth part P1 is lower than that of the weakened line formed by cutting out the side of the contact surface with the mouth part P1. (See Figure 8).

On the other hand, the right vertical weakened line 22B is a weakened line extending substantially perpendicularly from the right end side of the second horizontal weakened line 21 (see FIG. 6). This right vertical weakened line 22B is provided along the right side of the hinge 2 so as to be connected to the right end of the second horizontal weakened line 21 (see FIG. 7).

This right longitudinal weakening line 22B is provided at a position starting from a notch 25 provided at a position symmetrical to the notch 24 provided on the left longitudinal weakening line 22A (see FIG. 7). By extending these notches 24 and 25, they support other weakened lines such as the left vertical weakened line 22A and the right vertical weakened line 22B so that they can be easily cut.

Furthermore, the third horizontal weakened line 23 is a weakened line formed in the horizontal direction from the lower end of the right vertical weakened line 22B, and is formed to widen the separation range of the inner lid 1 (see FIG. 6). ). By cutting all the horizontally weakened lines, including the first horizontally weakened line 11, the second horizontally weakened line 21, and the third horizontally weakened line 23, the inner lid 1 is separated by about 1/3 of the circumference, and the opening P1 (See Figure 1).

FIG. 9 shows the process of tearing the inner lid 1 at the time of separate disposal. First, pull the top lid 3 toward you and cut each weakened line starting from the first horizontal weakened line 11 (see FIG. 3(a)). Next, the left vertical weakened line 22A is cut to open all the weakened lines (see figure (b)). Finally, put your finger on the wall of the released inner lid 1 and remove the cap from the container P using your thumb as support (see figure (c)).

Note that the configuration of the present invention is not limited to the illustrated example, and the configurations of the inner lid 1, hinge 2, upper lid 3, etc., and the positions and dimensions of the inner notch line 10 and the outer notch line 20 , etc. Any changes can be made without changing the gist of the invention.
