Description

The present invention relates to a seal lid in a container such as yogurt or pudding, particularly a container having a circular outer shape, and a method for opening the seal lid.

Japanese Patent Application Laid-Open No. 8-2558859 discloses that even when used for wrapping beverages such as yogurt for beverages and solids such as hail, it is easy to drink when drinking or eating the filling or A container with a sealed lid is proposed that can be easily eaten and can be unsealed, can be manufactured using existing injection molds, and does not require control of the sealing strength of the lid. ing.

As shown in FIG. 1, this container is sealed (sealed) by adhering a seal lid 3 on a flange portion 2 formed at the opening edge of the circular container 1. A knob piece (gripping allowance) 4 is formed integrally with the seal lid 3 so as to become a knob portion when the seal lid 3 is peeled off from the flange portion 2 and opened.
JP-A-8-258859

However, especially when the container 1 is circular, the sealing lid 3 that is strongly bonded is peeled off from the flange portion 2 just by providing the grip margin 4 as a gripping piece on the sealing lid 3 as described above. A very large opening force is required for opening, which is inconvenient when a weak person such as an infant or an elderly person opens.

The peeling action when the gripping allowance 4 is peeled off from the flange portion 2 in the circular container 1 has been investigated. When the gripping allowance 4 is picked and pulled up at the beginning of the opening operation, the tangential direction 5 direction of the circular flange portion 2 is determined. Since it is necessary to peel off the seal lid 3 against the adhesive force with the flange portion 2 in a wide range W, a large peeling force is required. Further, even if the region in the vicinity of the gripping allowance 4 is peeled off from the circular flange portion 2, it is necessary to peel off in the direction of the arrow a1 and the direction of the arrow a2 at the same time. . As a result, not only a large peeling force is required, but the larger the outer diameter of the container, the more difficult the peeling operation becomes, and the operation becomes difficult for infants and elderly people.

The technical problem of the present invention pays attention to such a problem, and realizes a sealing lid and a sealing lid opening method that can be easily and reliably opened even by a weak person such as an infant or an elderly person. There is.

The technical problem of the present invention is solved by the following means. According to a first aspect of the present invention, there is provided a sealing lid for a container, wherein a separating means for dividing the gripping margin into two is provided at a gripping margin portion of the sealing lid of the container. As described above, since the separation means for dividing the grip allowance into two parts is provided in the grip margin part of the seal lid of the container, when the seal cover is opened, the separation means is divided into two parts, First, by picking one of the two half-clamping allowances and then partially opening it, then picking the other two-minute grip allowance and opening the remaining seal lid, by performing partial opening twice , The whole can be opened.

A second aspect of the present invention is the container sealing lid according to the first aspect, wherein the separating means is a substantially V-shaped cutout portion or a cut or perforation having an arbitrary depth. As described above, when the separating means has a substantially V-shaped cutout portion, both sides of the V-shaped cutout portion have gripping allowances and two gripping allowances are formed. Therefore, it can be easily understood that each two-minute grip allowance is picked and the seal lid is opened in two steps. Moreover, since each two-minute grip allowance is separated via the V-shaped cutout portion, it is convenient to operate by opening each two-minute grip allowance.

In addition, when the separating means is cut or perforated, there is a difficulty that it is difficult to visually discriminate each of the divided halves and it is difficult to pick them separately, but the cut or perforation is separated. Utilizing the inertia of the operation, the opening operation for two minutes of the sealing lid itself becomes easy following the separation operation.

According to a third aspect of the present invention, in a container having a gripping allowance for opening operation on the seal lid of the container, and the gripping allowance is divided into two, first, the one half of the gripping allowance is picked up partially. After opening, the other two-minute grip allowance is picked, and the remaining seal lid is opened.

In this way, in the container in which the gripping allowance is divided into two by the substantially V-shaped notch portion as in claim 2, first, one of the two splitting allowances that are divided in half is picked and partially opened. After that, the other two-minute grip allowance can be picked and the remaining seal lid can be opened. Therefore, as in the conventional case, in a circular container, it is possible to easily and reliably open the container with a smaller force compared to a case where a single gripping margin is picked and the entire circumference of the container is opened at once. In other words, according to the opening method of claim 3, since each of the halved grip allowances is separately picked and opened, the sealing lid itself is also divided into two parts, and the sealing part is also peeled off by half on one side. Can be opened and the force required for opening is less than half. Therefore, even a weak person such as an infant or an elderly person can open it easily and surely with a light force.

According to a fourth aspect of the present invention, in a container having a grasping allowance for opening operation on the seal lid of the container, the grasping allowance is first divided into two parts, and then the one half of the two-minute grasping allowance is picked and partially opened. Then, the other two-minute grip allowance is picked, and the remaining seal lid part is opened. In the case where the gripping allowance of the seal lid is divided into two parts from the beginning by the V-shaped notch portion of claim 2, it is sufficient to pick and open the respective gripping parts by two minutes. In case of only the cut or perforation, as in claim 4, first, tear the cut or perforation and divide the grip allowance into two, and then pick the one half of the grip allowance. One side will be partially opened.

Thereafter, the remaining two-minute grip allowance is picked, and the remaining seal lid is opened, so that the entire seal lid can be opened. In this case, as compared with the method of claim 3, only the operation of tearing the cut or perforation and dividing the grip margin into two is added, and the force required for the opening operation is small, and it is easy to use with a light force. Since it can be opened reliably, it is suitable for those who are weak, such as infants and the elderly.

Since the separation means for dividing the grip allowance into two is provided in the grip margin portion of the seal lid of the container as in claim 1, when the seal lid is opened, the grip allowance is divided into two by the separation means. After that, first, the two half-clamping margins are picked and partially opened, and then the other two-minute gripping margins are picked and the remaining seal lid is opened twice. As a result, the whole can be opened.

If the separating means is a substantially V-shaped notched portion as in claim 2, both sides of the V-shaped notched portion are gripping allowances and two gripping allowances are formed. The Therefore, it can be easily understood that each two-minute grip allowance is picked and the seal lid is opened in two steps. Moreover, since each two-minute grip allowance is separated via the V-shaped cutout portion, it is convenient to operate by opening each two-minute grip allowance.

In addition, when the separating means is cut or perforated, there is a difficulty that it is difficult to visually discriminate each of the divided halves and it is difficult to pick them separately, but the cut or perforation is separated. Utilizing the inertia of the operation, the opening operation for two minutes of the sealing lid itself becomes easy following the separation operation.

In the container in which the gripping allowance is divided into two by the substantially V-shaped notch portion as in claim 2, as in claim 3, the part that is first divided into one half of the gripping allowance is divided. Then, the remaining seal lid can be opened by picking the other two-minute grip allowance. Therefore, as in the conventional case, in a circular container, it is possible to easily and reliably open the container with a smaller force compared to a case where a single gripping margin is picked and the entire circumference of the container is opened at once.

In other words, according to the opening method of claim 3, since each of the halved grip allowances is separately picked and opened, the sealing lid itself is also divided into two parts, and the sealing part is also peeled off by half on one side. Can be opened and the force required for opening is less than half. Therefore, even a weak person such as an infant or an elderly person can open it easily and surely with a light force.

In the case of a container having a cut or perforation on the seal lid according to claim 2, first of all, tear the cut or perforation to divide the grip allowance into two parts, and then divide one of the two divided parts into two. Then partially open one side. Thereafter, the remaining two-minute grip allowance is picked, and the remaining seal lid is opened, so that the entire seal lid can be opened. In this case, as compared with the method of claim 3, only the operation of tearing the cut or perforation and dividing the grip margin into two is added, and the force required for the opening operation is small, and it is easy to use with a light force. Since it can be opened reliably, it is suitable for those who are weak, such as infants and the elderly.

Next, an embodiment of how the container sealing lid and its opening method according to the present invention are practically described will be described. FIG. 2 is a perspective view of the container in which the sealing lid of the container according to the present invention is implemented. In the case of the present invention, a notch 6 that is recessed in a V shape toward the center of the container 1 is formed in the conventional gripping allowance 4 shown in FIG. As a result, the gripping allowance 4 in FIG. 1 is divided into two by the V-shaped notch 6, and two gripping allowances 41 and 42 are formed.

When the seal lid 3 is opened, the two gripping margins 41 and 42 are separately operated to peel off the seal lid 3. That is, first, when one gripping margin 41 is pulled up from the flange portion 2 and peeled off from the flange portion 2, the seal lid 3 is placed at the other gripping portion at the deepest portion of the V-shaped notch 6. When it is torn from the 42 side and pulled up further, as shown by the solid line 7, the seal lid 3 is further broken and opened. At the same time, only the gripping allowance 41 side is gradually peeled from the flange portion 2 in the direction of the arrow a1.

When further peeled off, the fracture portion 7 of the seal lid 3 extends in the direction of the arrow a3 and is broken from one end to the other end of the seal lid 3. At the same time, the peeling portion in the arrow a1 direction also advances in the arrow a1 direction, and finally the half circumference of the flange portion 2 is peeled off. Thus, when the half of the seal lid 3 of the flange portion 2 is peeled off, the remaining area 42 of the seal lid 3 is peeled off from the flange portion 2 when the remaining gripping margin 42 is picked and peeled off. Also at this time, it is peeled off first from the vicinity of the gripping allowance 42 and gradually peeled off along the flange portion 2 in the direction of the arrow a2.

In this way, if the gripping allowance 4 in FIG. 1 is divided into two to form two gripping allowances 41 and 42, and the peeling operation is performed separately, the first peeling operation by the gripping allowances 41 and 42 is circular. It is not necessary to peel off a wide region in the tangential direction of the container, and it is sufficient to peel only a narrow region extending over the width of the flange portion 2, so that an infant or an elderly person can easily peel off the seal lid. When the grip margin 41 is first peeled off, the seal lid 3 needs to be broken, so that a force for the breaking operation is required, but the force is extremely small. Therefore, although the gripping allowance 4 is divided into two, the opening operation needs to be performed twice, but a small force that can be opened even by an infant or an elderly person is sufficient.

FIG. 3 shows another embodiment of the V-shaped notch 6. The V-shaped notch 6 in FIG. 2 is deeply formed until it contacts the outer peripheral portion of the flange portion 2, whereas the notch 61 in FIG. 3 is not in contact with the outer peripheral portion 21 of the flange portion 2. Shallow cutout. In this way, when the notch is shallow, the gripping margin 41 is lifted from the left gripping margin 42 by pulling up the other gripping margin 41 with the right hand while holding the one gripping margin 42 with the fingers of the left hand. Tear apart. Subsequently, when the gripping allowance 41 is picked and peeled off from the flange portion 2, the half on one side is peeled off from the flange portion 2 in the same manner as in FIG. Next, the remaining gripping margin 42 is peeled off, and the remaining seal lid 3 is peeled off from the flange portion 2.

On the other hand, in the case of FIG. 2, the V-shaped notch 6 is deeply formed so as to reach the outer peripheral portion of the flange portion 2, so that the two gripping allowances 41 and 42 are bent together. Since there is no portion and the stability is good, even if the other gripping margin 42 is not held and supported by hand, only the right gripping margin 41 can be operated to smoothly and reliably peel off from the flange portion 2. It is easy to use.

4 and 5 show an embodiment in which the V-shaped notches 6 and 61 are not provided. Although the appearance is similar to the conventional gripping allowance 4 in FIG. 1, a notch 8 for dividing the gripping allowance into 41 and 42 is provided. This cut 8 may also be provided halfway so as not to reach the flange portion 2 and completely separate from the grip allowances 41 and 42 at the time of opening, and then peeled off from the flange portion 2, If a deep cut is made so as to reach the outer peripheral portion 21 of the flange portion 2, the opening operation can be performed by picking only one gripping margin 41 or 42 with a finger with only one hand.

FIG. 5 shows an embodiment in which a perforation 9 is provided instead of the cut 8. In the case of the cut line 8, the two gripping margins 41 and 42 are completely divided into two from the beginning, whereas in the case of the perforation 9, the gripping margins 41 and 42 are integrated. At the time of opening, the gripping allowances 41 and 42 are held in both hands, the perforation 9 is torn, and only one gripping allowance 41 is picked with a finger and peeled off from the flange portion 2. When there is a perforation 9 in this way, subsequent to the separation operation of the perforation 9, it is possible to peel from the flange portion 2 by a continuous operation, so using the inertia of the separation operation of the perforation 9, Peeling operation for opening is possible.

Various materials for the seal lid 3 have been put to practical use. For example, in the case of aluminum foil or the like, it can be easily torn like the tearing portion 7 in FIG. 2, but in the case of a synthetic resin sheet, the tensile force is strong. In many cases, it cannot be broken. Even in such a case, when the gripping allowance 41 is peeled off at the start of the opening operation and at the same time the gripping allowance 41 is peeled off along the flange portion 2 in the direction of the arrow a1, finally the other gripping allowance 42 is reached. The entire circumference can also be peeled off. The present invention is particularly effective for a circular container, but is not limited to a circular shape.

As described above, if the conventional gripping allowance is divided into two to form two gripping allowances, the peeling area when only one gripping allowance is peeled off is small. Can easily and reliably peel off the sealing lid, contributing to the spirit of universal design.

It is a perspective view which shows the grip margin of the seal lid in the conventional circular container. It is a perspective view which shows the container which implemented the V-shaped notch seal lid by this invention. It is a principal part top view which shows other embodiment of a V-shaped notch. It is a principal part top view of embodiment which replaced with the V-shaped notch and made the cut. It is a principal part top view of embodiment which replaced with a cut and put the perforation.
