Description

  The present invention relates to a hermetic container suitable for housing various contents such as foods such as butter and margarine, cosmetics, and wet sheets.

  This type of sealed container is mainly composed of a cup-shaped container main body that generally contains contents and a lid that covers the container main body. Usually, the lid is designed so as to cover the container body without any gap, and the sealing is ensured in order to prevent the contents from being dried and to maintain hygiene.

As one of such sealed containers, it is mainly composed of a container body in which a fitting wall and a flange portion are formed over the entire circumference of the opening, and a lid body in which a fitting edge portion is formed on the periphery. A sealed container is known (see Patent Document 1).
The fitting edge portion is adapted to be fitted to the outside of the fitting wall when the lid body is put on the container body and to come into contact with the flange portion. Thereby, a cover body can be covered with no gap with respect to a container main body, and the contents can be sealed now.
JP 2003-252358 A

By the way, this type of container is not placed in one place for a long time and is likely to be carried frequently. In particular, when the contents are butter, margarine, etc., the sealed container is carried with each meal. In this case, there are many cases where the container body is carried while being gripped through the lid, or is carried while gripping the protrusion of the buttock of the container body.
However, when the container main body is gripped through the lid, the lid may come off due to the weight of the container main body when it is lifted. On the other hand, when the protruding portion of the collar portion is grasped, there is a possibility that the collar portion may be bent due to the weight of the container main body when it is lifted, and there is a possibility that the container main body may be loose. In other words, the conventional sealed container may be dropped or wobbled when carried, and lacks a sense of stability in carrying.

  The present invention has been made in consideration of such circumstances, and an object thereof is to provide a high-quality sealed container that can ensure high sealing performance and can be stably carried by anyone. .

In order to achieve the above object, the present invention provides the following means.
A sealed container according to the present invention is a sealed container including a container main body for storing contents and a lid for covering the container main body, wherein the container main body includes a cup-shaped container having an open upper end. A flange portion extending outward from the outer peripheral surface of the container along the opening; a peripheral wall formed in a frame shape surrounding the periphery of the container; A pair of engagement hole portions formed at least one engagement hole formed at positions opposite to each other across the container, and the lid body covers the opening of the container A pair of claw portions provided on a peripheral edge of the top plate and disposed on the inner surface side of the peripheral wall and having a claw body engaged with the engagement hole, and one claw of the pair of claw portions A hinge portion interposed between the portion and the top plate, and the peripheral wall includes the pair of claws Among so as to sandwich the engaging hole portion other claw portion is engaged along said opening, characterized in that the weakened portion breakable towards the upper end is formed from the lower end.

In the sealed container according to the present invention, in a state where the cover body covers the container body, the pair of claws are fitted into the pair of engagement holes with the top plate covering the opening of the container. Is engaged. In detail, the nail | claw body of a pair of nail | claw part fits and engages with the engagement hole of a pair of engagement hole part, respectively. Therefore, the lid can be reliably closed while ensuring high sealing performance, and the contents can be reliably stored.
In addition, the pair of claws that are fitted in the pair of engagement holes are arranged so as to be hidden on the inner surface side of the peripheral wall of the container body, and thus are not completely exposed to the outside. That is, it is difficult to touch the pair of claws when the lid body covers the container body. Therefore, when carrying, it can make it difficult to generate | occur | produce that these nail | claw parts are touched accidentally and engagement is cancelled | released.

  Moreover, since a pair of nail | claw part is arrange | positioned inside the surrounding wall, when it is the state which has covered the cover body, the top plate is mainly exposed. However, since there is no place on the top plate that can be gripped, it is difficult to lift the sealed container through the lid as in the prior art. For this reason, the peripheral wall of the container body is inevitably grasped and lifted. Accordingly, it is possible to make it difficult for the container main body to come off from the lid and fall when being carried.

By the way, the flange part which comprises a container main body is formed along the opening of a container, and the surrounding wall formed in frame shape is continuously arranged in the periphery. Therefore, the flange portion has high rigidity, and is particularly difficult to bend in the height direction of the container. Therefore, even if the closed container is lifted while holding the peripheral wall, the flange portion is deformed by the weight of the container main body, and there is little risk of wobbling.
Thus, according to this sealed container, since it is difficult for the container main body to fall from the lid or to wobble, it is possible for anyone to carry it stably and improve quality. You can plan.

  Moreover, since the weakened part is formed in the surrounding wall of a container main body, it can be discriminate | determined whether the cover body was opened illegally by confirming the fracture condition of the weakened part at the stage of unused. That is, unless the weakened portion is broken and a part of the peripheral wall surrounded by the weakened portion is lifted up, the nail cannot be pushed up to release the engagement of the other nail, so the lid is opened. I can't. Therefore, it is possible to determine at a glance whether or not the tampering has been opened simply by confirming the breaking state of the weakened portion. In this respect as well, it is possible to improve the quality of the sealed container and to improve the reliability of the quality of the contents.

Next, when it is desired to take out the contents after breaking the weakened portion, a part of the peripheral wall surrounded by the weakened portion is rolled up. Then, since the other nail | claw part fitted and engaged with the engagement hole part is exposed, the nail | claw body of this nail | claw part can be pushed up and engagement can be cancelled | released. Here, the top plate of the lid can be opened / closed around a hinge portion interposed between one of the pair of claw portions. Therefore, the lid can be opened after the engagement of the other claw portion is released. Thereby, the contents accommodated in the container can be taken out.
In particular, the lid has a structure in which one of the claw portions is engaged with and engaged with the engagement hole portion, so that the lid body is not separated from the container body even while the contents are being taken out. For this reason, the lid body is not accidentally lost or dropped and attached with dust or the like.

  When the lid is assembled to the container main body filled with the contents at the stage of shipping the sealed container, the pair of claws are fitted into the pair of engaging holes, and the two are combined. Can do. Therefore, the assemblability is extremely excellent, and efficient shipping can be performed.

  Further, the sealed container according to the present invention is the sealed container according to the present invention, wherein the flange portion is formed at a position away from the upper edge to the bottom side so that the upper end of the container is protruded by a certain amount, The peripheral edge of the top plate enters the gap between the upper end of the container and the peripheral wall.

  In the sealed container according to the present invention, when the lid is put on the container body, the peripheral edge of the top plate enters the gap between the upper end of the container and the peripheral wall, and thus the sealing performance can be further improved. . Therefore, the contents can be stored for a longer period.

  Further, the sealed container according to the present invention is characterized in that, in the sealed container of the present invention, the container is formed with a rib for pressing the claw body of the one claw portion against the inner surface of the peripheral wall. And

  In the sealed container according to the present invention, since the claw body of one claw portion is pressed against the inner surface of the peripheral wall by the rib, rattling is suppressed and a more reliable engagement state is maintained. In particular, when the top plate opens and closes around the hinge portion, stress concentrates near one of the claw portions. However, since the backlash of the claw body of one claw part is suppressed by the rib, the top plate can be smoothly opened and closed, and it becomes easier to use.

  The sealed container according to the present invention is the sealed container of the present invention described above, wherein the top plate is sandwiched between the peripheral wall when the top plate is in an open state, and the top plate is caused by frictional resistance. Protrusions that maintain the open state are provided.

  In the sealed container according to the present invention, when the top plate is opened around the hinge portion, the projection is sandwiched between the top plate and the peripheral wall, and the top plate returns to the original closed state due to frictional resistance against the peripheral wall. To prevent it. Therefore, the top plate can be kept open while the contents are being taken out. Therefore, it is possible to provide a sealed container that is easier to use.

  According to the sealed container according to the present invention, it is possible to ensure high sealing performance and store the contents reliably, and anyone can carry it stably. Therefore, it can be set as a high quality sealed container.

(First embodiment)
Hereinafter, 1st Embodiment of the airtight container which concerns on this invention is described with reference to FIGS. As shown in FIGS. 1 and 2, the sealed container 1 of the present embodiment is mainly composed of a container main body 2 that stores contents W such as butter and margarine, and a lid 3 that covers the container main body 2. It is a box-shaped container with high airtightness.

The container body 2 is formed by, for example, injection molding of a synthetic resin applicable to a container such as food, and as shown in FIG. 3, the container 10 and the flange portion 11 that are integrally formed. And the peripheral wall 12.
The container 10 is formed in a cup shape having an open upper end. Specifically, it has a substantially rectangular shape when viewed from above, and is formed to a depth that can sufficiently accommodate the contents W. Further, the corner is formed to be slightly rounded.

As shown in FIGS. 1 to 3, the flange portion 11 is formed to extend substantially horizontally from the outer peripheral surface of the container 10 toward the outside along the opening. The peripheral wall 12 is connected to the periphery of the flange portion 11 in a state of being formed in a frame shape so as to surround the periphery of the container 10. At this time, the peripheral wall 12 is connected to the flange portion 11 so that the upper end edge is located above the upper surface of the flange portion 11.
In addition, the flange portion 11 is formed with a pair of engagement hole portions 26 including one engagement hole 13 at positions opposite to each other with the container 10 in between. In the present embodiment, a case where the pair of engaging hole portions 26 are formed so as to be aligned along the longitudinal direction of the container 10 (the direction of arrow A shown in FIG. 3) will be described as an example.

The lid 3 is formed by, for example, injection molding a synthetic resin that can be applied to a container such as a food, like the container body 2, and as shown in FIG. The claw portions 21 and 22 and the hinge portion 23 are mainly configured.
As shown in FIGS. 1, 2, and 4, the top plate 20 is formed in a substantially rectangular shape in a top view so as to cover the opening of the container 10 and the flange portion 11. At this time, the corners are rounded. In addition, a bulging portion 20a that is bulged and formed so as to swell slightly upward is formed in the approximate center of the top plate 20.

  The pair of claw portions 21 and 22 are provided so as to hang downward from the periphery of the top plate 20, and have claw bodies 21 a and 22 a that are fitted into the engagement holes 13 and engaged. Yes. At this time, the pair of claw portions 21 and 22 are provided so as to be aligned along the longitudinal direction of the container 10 (the direction of the arrow A shown in FIG. 4). As shown in FIGS. 1 and 2, the pair of engagement holes 26 of the container body 2 are engaged with each other. In particular, since the pair of engagement hole portions 26 are formed in the flange portion 11 disposed on the inner side of the peripheral wall 12, the pair of claw portions 21 and 22 are disposed so as to be hidden on the inner surface side of the peripheral wall 12 when engaged. And is not completely exposed to the outside.

As shown in FIGS. 1 and 4, the hinge portion 23 is provided so as to be interposed between one claw portion 21 and the top plate 20 of the pair of claw portions 21 and 22. Therefore, as shown in FIG. 5, the top plate 20 can be opened and closed with the hinge portion 23 as the center. That is, if the engagement of the other claw portion 22 is released, the top plate 20 can be opened and closed even when the one claw portion 21 is engaged with the engagement hole portion 26.
Further, as shown in FIG. 4, a protrusion 24 is provided on the top surface of the top plate 20 at a position directly above one of the claw portions 21. As shown in FIG. 5, the protrusion 24 is sandwiched between the peripheral wall 12 when the top plate 20 is in an open state, and plays a role of maintaining the top plate 20 in an open state by frictional resistance. .

By the way, as shown in FIG. 3, a part of the peripheral wall 12 is a knob 12 a surrounded by two weakening lines (weakening portions) 15. The weakening line 15 is a breakable line formed from the lower end to the upper end of the peripheral wall 12, and is an engagement in which the other claw portion 22 of the pair of claw portions 21 and 22 is detachably engaged. The holes 26 are provided on both sides so as to sandwich the hole 26 along the opening of the container 10.
In FIG. 3, the left engagement hole 26 is a hole in which one claw 21 is fitted and engaged with the paper surface, and the right engagement hole 26 is the other claw with respect to the paper surface. It is a hole into which the portion 22 is fitted and engaged. On the other hand, in FIG. 4, one claw portion 21 is illustrated on the right side with respect to the paper surface, and the other claw portion 22 is illustrated on the left side with respect to the paper surface. That is, the lid 3 shown in FIG. 4 is shown in a state where the orientation is rotated by 180 degrees for easy viewing of the drawing.

  As described above, since the knob 12a is surrounded by the two weakening lines 15, it can be lifted upward after the weakening line 15 is broken. That is, since the upper end of the peripheral wall 12 acts like a hinge, the knob 12a is swung up around this upper end. When the knob 12a is lifted up, the other claw portion 22 engaged with the engagement hole portion 26 is exposed, so that the claw body 22a of the other claw portion 22 is removed from the engagement hole 13. Designed to push up and disengage. It is also possible to completely separate and remove the knob 12a.

  Further, a rib 25 is formed on the outer peripheral surface of the container 10 to press the claw body 21a of the claw portion 21 against the inner surface of the peripheral wall 12 when one claw portion 21 is engaged as shown in FIG. Has been. Thereby, since the nail | claw body 21a of the one nail | claw part 21 engaged is pressed on the inner surface of the surrounding wall 12, rattling is suppressed.

Next, the case where the sealed container 1 configured in this way is used will be described. The airtight container 1 will be described on the assumption that the weakening line 15 is not yet broken.
First, it is possible to determine whether or not the lid 3 has been tampered with by checking the breaking state of the weakening line 15 formed on the peripheral wall 12 of the container body 2. That is, unless the weakening line 15 is broken and a part of the peripheral wall 12 surrounded by the weakening line 15, that is, the knob 12 a is lifted up, the claw body 22 a of the other claw portion 22 is pushed up from the engagement hole 13. Since the engaged state cannot be released, the lid 3 cannot be opened. Therefore, it is possible to easily and reliably determine at a glance whether or not the tampering has been opened simply by confirming the breaking state of the weakening line 15.
At this time, if the knob 12a is completely separated and removed, the above-described determination can be made more clearly.

When misbehaving such as the lid 3 being opened illegally by mischief when being lined up in the distribution process or at the storefront, not only will the reliability of the product be impaired, but the consumer may be harmed. There is a possibility of joining.
However, according to the sealed container 1 of the present embodiment, the weakening line 15 is present at an easily viewable position, and the lid 3 cannot be opened unless the weakening line 15 is broken. Whether or not can be determined instantaneously and accurately. Therefore, it is possible to improve the reliability of the quality of the contents W and to improve the quality and reliability of the sealed container 1 itself.

  Next, when taking out the contents W, first, the weakening line 15 is broken and the knob 12a surrounded by the weakening line 15 is lifted upward. Then, since the other claw part 22 engaged with the claw body 22a fitted in the engagement hole 13 is exposed, the claw body 22a of the claw part 22 can be pushed up to release the engagement. It is also possible to simultaneously perform the operation of raising the knob 12a and the other pushing operation in a series of flows. Since the top plate 20 can be opened and closed around the hinge portion 23, the lid 3 can be opened as shown in FIG. 5 by releasing the engagement of the other claw portion 22. Thereby, the contents W accommodated in the container 10 can be taken out. In addition, the container 10 is accommodated in the state covered with the thin sheet | seat S (aluminum foil, a resin film, etc.).

  In particular, the lid 3 has a configuration in which the one claw portion 21 is engaged with and engaged with the engagement hole portion 26, so that the lid 3 is not separated from the container body 2 even while the contents W are being taken out. ing. For this reason, the lid 3 is not accidentally lost or dropped, and dust or the like adheres to it and does not get dirty. Moreover, when the top plate 20 is opened, the protrusion 24 is sandwiched between the peripheral wall 12 and the top plate 20 is prevented from returning to the original closed state due to frictional resistance against the peripheral wall 12. Therefore, the top plate 20 can be kept open while the contents W are being taken out. Therefore, it is very easy to use.

  In addition, since the claw body 21a of the one claw portion 21 is pressed against the inner surface of the peripheral wall 12 by the rib 25, rattling is suppressed and a reliable engagement state is maintained. In particular, when the top plate 20 opens and closes around the hinge portion 23, stress tends to concentrate near the one claw portion 21. However, since the backlash of the claw body 21a of the one claw portion 21 is suppressed by the rib 25, the top plate 20 can be opened and closed smoothly. Therefore, it can be said that it is easy to use also in this respect.

  Next, when the lid 3 is closed after the contents W are taken out, the claw body 22a of the other claw portion 22 is engaged with the engagement hole portion while the top plate 20 is returned with a force against the frictional resistance of the projection portion 24. 26 is engaged with the engagement holes 13. Then, as shown in FIGS. 1 and 2, the top plate 20 is securely fixed in a state of covering the opening of the container 10 and the flange portion 11. Accordingly, the lid can be reliably closed while ensuring high sealing performance, and the contents W can be reliably stored.

  In addition, the closed container 1 that has been picked up or separated and lifted up is disposed so that the outer peripheral edge of the lid 3 is hidden on the inner surface side of the peripheral wall 12 during storage. When the lid 3 is covered, the top plate 20 is mainly exposed. However, since there is no place on the top plate 20 that can be gripped, it is difficult to lift the sealed container 1 through the lid 3 as in the prior art. Therefore, the peripheral wall 12 of the container body 2 is inevitably grasped and lifted. Accordingly, it is possible to make it difficult for the container body 2 to come off from the lid 3 and fall when being carried.

  By the way, the flange part 11 which comprises the container main body 2 is formed along the opening of the container 10, and the peripheral wall 12 formed in the shape of a frame is continuously provided in the periphery. Therefore, the flange portion 11 has high rigidity, and is particularly difficult to bend in the height direction of the container 10. Therefore, even if the closed container 1 is lifted while holding the peripheral wall 12, the flange portion 11 is deformed by the weight of the container body 2 and there is little possibility of wobbling.

  As described above, according to the sealed container 1 of the present embodiment, since the container main body 2 is unlikely to drop from the lid 3 or wobble or the like when being carried, anyone can carry it stably. It is possible to improve the quality.

  When the lid 3 is assembled to the container body 2 filled with the contents W at the stage of shipping the sealed container 1 of the present embodiment, the claw bodies 21a and 22a of the pair of claw portions 21 and 22 are paired with the pair of claw bodies 21a and 22a. The both can be easily combined by simply engaging and engaging with the engagement holes 13 of the engagement holes 26. Therefore, the assemblability is extremely excellent, and efficient shipping can be performed.

(Second Embodiment)
Next, 2nd Embodiment of the airtight container which concerns on this invention is described with reference to FIGS. In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted. The main difference between the second embodiment and the first embodiment is that the position of the flange portion 11 is different.

As shown in FIGS. 6 to 8, the sealed container 30 of the present embodiment includes a container body 31 and a lid body 32.
The container body 31 of the present embodiment is formed at a position away from the upper edge 10a toward the bottom so that the flange portion 11 protrudes the upper edge 10a of the container 10 by a certain amount. The top plate 20 of the lid body 32 has a peripheral edge bent slightly downward so as to enter a gap between the protruding upper end edge 10 a of the housing 10 and the peripheral wall 12. Therefore, according to the sealed container 30 of the present embodiment, when the lid 32 is put on the container main body 31, the sealing performance can be further improved, and the contents W can be stored for a longer period. ing.
Other functions and effects are the same as those of the first embodiment.

  The technical scope of the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.

  For example, in each of the embodiments described above, a closed container for food containing contents such as margarine and butter is used. However, the present invention is not limited to a container used for food. For example, it may be a container for storing contents such as cosmetics and wet sheets.

  Moreover, in each said embodiment, although it was set as the structure which has arrange | positioned a pair of engaging hole part and a pair of nail | claw part along the longitudinal direction of a container, it is good also as a structure arrange | positioned along a transversal direction. Even in this case, the same effect can be obtained only by changing the opening and closing direction of the lid.

Moreover, in each said embodiment, it was set as the structure in which a pair of engagement hole part has one engagement hole, respectively, However, The number of engagement holes may be more than one. For example, a pair of engagement holes having three engagement holes may be used. Furthermore, the number of engagement holes included in one engagement hole may be different from the number of engagement holes included in the other engagement hole. For example, one engagement hole may have three engagement holes, and the other engagement hole may have one engagement hole.
On the other hand, as described above, when the number of the engagement holes is changed, the number of the claw bodies respectively included in the pair of claw portions may be appropriately changed. For example, when the number of engagement holes is three, a claw portion having three claw bodies according to this number may be used. However, it is not always necessary to match the number of the claw bodies to the number of the engagement holes. Even if the number of the engagement holes is 3, the number of the claw bodies may be one or two. Even in this case, since the claw body is fitted into the engagement hole and engaged, the claw portion and the engagement hole portion can be brought into the engaged state.
As described above, the combination of the number of the engagement holes and the number of the claw bodies may be freely designed, and the optimum combination may be selected from many combinations according to the use of the sealed container and the like. It ’s fine.

Furthermore, in order to make it easy to distinguish between a nail body of one nail part and a nail body of the other nail part of the pair of nail parts, the shapes of both nail bodies may be different. The same applies to the engagement holes of the pair of engagement holes.
Moreover, in the said embodiment, you may form a flange part intermittently along opening of a container. In this case, the intermittent portion of the flange portion can be used as the engagement hole.

  Moreover, in each said embodiment, although the container was made into the top view rectangular shape, it is not limited to this shape. For example, a top-view elliptical shape, a top-view circular shape, a top-view square shape, or a top-view square shape may be used. At this time, the shape of the lid may be appropriately changed according to the shape of the container.
