However, the work of sticking the seal is complicated, and if there is a sticking error, the container will be lost. Further, it is troublesome to peel off the seal and open it, and a structure capable of solving such a problem is demanded.

The present invention proposes a paper container that does not require a seal for fastening the lid to the container body.

A first aspect of the present invention is a paper container main body having a circular bottom portion and a cylindrical peripheral wall portion rising from an outer edge portion of the bottom portion, and a paper container body having an opening opening upward at an upper end of the peripheral wall portion. A container having a circular zenith portion and an annular fitting peripheral portion formed on an outer edge of the zenith portion, the fitting peripheral portion being externally fitted to the peripheral wall portion of the container body. A paper container provided with a paper lid for closing the opening of the main body, wherein at least an exposed portion of the peripheral wall of the container main body that is not covered by the fitting peripheral portion of the lid is at least A pair of slits are provided so as to be opposed to each other, and further, a long flat material made of paper is provided, and at both ends of the long flat material, insert piece portions to be inserted into the respective slits of the container body are respectively provided , The opening part of the container body is closed by inserting the insertion piece part into each slit of the container body in a state in which the long flat member is arranged via the zenith part of the lid body. A paper container, characterized in that it holds the lid.

In this configuration, the long flat member holds the lid closed state between the lid and the container body, and thus does not require a seal attached to the lid and the container body. Therefore, the cost of this seal can be reduced. In general, an increase in the cost required for the long flat material can be suppressed by the cost reduction due to the need for the seal.

Further, in such a configuration, in a state where the fitting peripheral portion of the lid body is externally fitted to the peripheral wall portion of the container body to close the opening of the container body (hereinafter, referred to as a lid closed state), the container A long flat member inserted into each slit of the main body is arranged on the zenith of the lid. For this reason, when stacking a plurality of the containers up and down, the upper container body is placed on the lower long flat material, so that the container can be stacked relatively stably, and the stacked state is relatively stable. Then you can keep it. This makes it possible to relatively easily stack the paper containers of the present invention in a vertical stack, and to prevent the paper containers from collapsing in a stack.

In addition, this configuration employs a long flat member having a simple shape with insertion pieces provided at both ends, which can suppress an increase in manufacturing cost and is good in appearance. Furthermore, it is not necessary to dispose a pad of another member when stacking, and a situation in which the customer has to remove a pad that is unnecessary for the customer does not occur.

In the above-described paper container of the present invention, the long flat member is provided with a length substantially the same as the outer diameter of the lid body, and the main stacking portion arranged on the zenith portion of the lid body and the main stacking portion. A configuration is proposed in which each of the side flat portions extends downward from both side edges, and an insertion piece portion is provided at each tip of the side flat portion.

In such a configuration, the plurality of paper containers can be stably stacked vertically by the main stacking part of the long flat material arranged on the zenith part of the lid body, and the above-described operational effects of the present invention. Is stably exhibited. Further, in this configuration, since the side flat portion of the long flat member is arranged outside the peripheral wall portion of the container body and the fitting peripheral portion of the lid, the side flat portion serves as the lower surface of the paper container. Can be placed horizontally. Further, even when it is placed horizontally, it can be stably held in the lid closed state by the long flat material. Here, a general cylindrical container rolls easily when placed horizontally, and it is difficult to place it stably.However, as described above, the container of the present invention is stable due to the side flat portion of the long flat member. And can be placed horizontally.
Therefore, according to this configuration, it is possible to display not only in a vertically stacked state but also in a horizontal position, and therefore, there is an excellent advantage that the vertical position or the horizontal position can be selected depending on the display place.

In the above-described paper container of the present invention, the slits provided in the peripheral wall portion of the container body are formed along the circumferential direction of the peripheral wall portion, and the insertion piece portions provided at both ends of the long flat material. Is formed by being inserted into the inside of the container body through the slit, so that the lower part of the insertion is connected to the lower part of the slit, and the upper edge of the lower part of the insertion is linked upward. A configuration is proposed in which the upper part is provided above the slit by being inserted inside the container body.

In such a configuration, the insertion piece portion of the long flat material can be relatively easily inserted into the slit of the container body, and once the insertion piece portion is inserted into the slit, it is difficult to remove, Stable hold in the inserted state. According to the long flat member having this configuration, the closed state of the container body and the lid can be held more stably.

In the above-described paper container of the present invention, there is proposed a configuration in which an easy-cutting portion for dividing the long flat material is provided between both insertion piece portions of the long flat material.

According to such a configuration, the long flat material can be divided by the easy-cutting portion, so that the fitting between the lid and the container main body can be released without removing the insertion piece portion of the long flat material from the slit of the container main body ( The opening of the container body can be opened). Thus, the customer can take out the contents stored in the container body by cutting the easy-cutting portion of the long flat material after the purchase.

One of the lids is provided with a slit, and the other of the container body and the lid is provided with an insert piece that is inserted into the slit, and the insert piece is By being inserted into the inside of the container main body or the inside of the lid through the slit, the one side insertion portion arranged on one side of the slit and the one side insertion portion is connected to one side from one edge. And the other side insertion part arranged on the other side of the slit by being inserted into the inside of the container body or the inside of the lid through the slit. It is a container.

In this configuration, similarly to the above configuration, the insertion piece portion is unlikely to come out of the slit, so that the lid body is unlikely to be removed from the container body. Therefore, a seal for fastening the lid to the container body is unnecessary. Further, there is an advantage that the paper container has a small number of parts as a whole.

A third invention is a paper container provided with a paper container body having an opening and a paper lid for closing the opening of the container body. At least one pair of slits are provided on one of the lids so as to face each other, and further, a long oblong material made of paper is provided, and insertion pieces inserted into the slits are provided at both ends of the long oblong material. Sections are respectively provided, and the insertion piece portions are respectively inserted into the slits of the container body or the lid body in a state in which the long flat member is arranged via the other of the container body and the lid body. By holding the lid body that closes the opening of the container body, the insertion piece portion is inserted into the container body inner side or the lid body inner side through the slit. , One side insertion portion arranged on one side of the slit and one edge of the one side insertion portion are connected to one side, and the inside of the container body or the inside of the lid body is formed through the slit. It is a paper container provided with the other side insertion part arrange|positioned on the other side of the said slit by being inserted.

With such a configuration, it is possible to make the container body and the lid body have a relatively simple structure and prevent the lid body from coming off from the container body. Therefore, a seal for fastening the lid to the container body is unnecessary.

Here, an easy-cutting portion may be provided in the vicinity of the insertion piece to divide the vicinity.

With such a configuration, similarly to the above, a state in which the fitting between the lid and the container body can be released (a state in which the opening of the container body can be opened) without removing the insertion piece from the slit it can. Thereby, the contents stored in the container body can be taken out by cutting the easy-cutting portion.

Further, the container main body or the lid body provided with the slit is formed of a polyhedron, the slit is provided on a corner portion formed by abutting wall surface portions and wall surface portions adjacent to each other, the insertion piece Part is inserted into the inside of the container body or the inside of the lid through the slit so that the one side insertion part abuts one wall surface part and the other side insertion part abuts the other wall surface part. A contact structure is proposed.

With this configuration, the inserted insertion piece is sandwiched between the wall surface portions, and the both insertion portions are further strongly pressed against the wall surface portion, and the insertion piece portion is significantly slit. The structure makes it difficult to pull out.

Further, in the above configuration, the peripheral wall portion of the container body or the lid provided with the slit is a double-wall structure consisting of an outer wall and an inner wall, the slit is formed in the outer wall, A configuration is proposed in which an opening for removal facing the slit is formed in the inner wall.

With this configuration, both insertion portions of the insertion piece portion inserted through the slit are pinched from the inner wall side through the opening for removal, so that the insertion piece portion can be easily removed from the slit. It is possible to remove it.

According to the paper container of the first aspect of the present invention, there is an effect that a seal for fixing the lid body to the container body is unnecessary.

The second aspect of the present invention has an effect that the lid body is unlikely to come off from the container body and the seal is unnecessary, with a simple structure as a whole.

The third aspect of the present invention can provide a paper container in which the lid does not easily come off from the container body and the seal is unnecessary, without forming a complicated structure in the container body and the lid.

Embodiments of the present invention will be described according to the following examples. It should be noted that the present invention is not limited to the following embodiments, and design changes can be appropriately made. Further, when describing the container, the vertical direction is specified for simplicity of description, but the present invention is not limited to this direction and is used in any usage mode. It is included in the present invention. Further, since the structure of the present invention is made of paper, it has a portion in which the sheets of paper are overlapped, but this portion is not shown for the sake of simplicity of description. Further, the illustration of the contents stored in the paper container 1 is omitted.

As shown in FIGS. 1 to 4, a paper container 1 of the present embodiment includes a bottomed cylindrical container body 2, a lid body 3 that closes an opening 14 of the container body 2, and a lid body 3. The long flat member 4 that holds the opening 14 in a closed state is provided. Here, the container body 2, the lid body 3, and the long flat member 4 are all made of paper. Since the long flat member 4 is an essential part of the present invention, its details will be described later.

The container body 2 is composed of a circular bottom portion 11 and a cylindrical peripheral wall portion 12, and has a bottomed tubular shape having the opening portion 14 that opens upward. At the lower end of the peripheral wall portion 12, a body curl portion 13 that is internally curled is formed. The peripheral wall portion 12 and the bottom portion 11 are joined to each other with the outer peripheral edge of the bottom portion 11 abutting on the upper portion of the main body curl portion 13 of the peripheral wall portion 12.

The lid 3 is composed of a circular zenith portion 21 and a cylindrical fitting peripheral portion 22, and the fitting peripheral portion 22 is formed on the upper portion of the container body 2 so as to be externally fitted. At the upper end of the fitting peripheral portion 22, a lid curl portion 23 that is internally curled is formed. The fitting peripheral portion 22 and the zenith portion 21 are joined to the lower portion of the lid curl portion 23 of the fitting peripheral portion 22 in a state where the outer peripheral edge of the zenith portion 21 is abutted.

Here, the lid 3 is fitted with the fitting peripheral portion 22 so as to be relatively easily slidable with respect to the container body 2 in a state where the fitting peripheral portion 22 is fitted onto the upper part of the container body 2. The inner diameter of the peripheral portion 22 is set to be slightly larger than the outer diameter of the peripheral wall portion 12. Thereby, the lid body 3 can be fitted into the container body 2 relatively easily, and the lid body 3 can be removed relatively easily from the fitted state.

Further, in the lid body 3, the vertical dimension of the fitting peripheral portion 22 is set shorter than the vertical dimension of the peripheral wall portion 12. Therefore, the peripheral wall portion 12 of the container body 2 is covered with the fitting peripheral portion 22 of the lid body 12 in a state where the opening portion 14 is closed by the lid body 3 (a lid closed state described later). And an exposed portion 12b that is not covered by the fitting peripheral portion 22.

The container body 2 and the lid body 3 are fitted to each other by fitting the fitting peripheral portion 22 of the lid body 3 onto the upper portion (fitted portion 12a) of the peripheral wall portion 12 of the container body 2 so that the container body 2 is covered. The opening 14 is closed by the lid 3. The state in which the lid 3 is fitted to the upper portion of the container body 2 and the opening 14 is closed in this manner is hereinafter referred to as a lid-closed state.

When stacking the lid-closed ones (a pair of the container body 2 and the lid body 3) vertically, the lid curl portion 23 of the lower lid body 3 is inserted into the body curl of the upper vessel body 2. The parts 13 come into contact with each other and can be stacked only in an unstable manner. This is because the inner diameter of the lid body 3 (fitting peripheral portion 22) is set slightly larger than the outer diameter of the container body 2 (peripheral wall portion 12) as described above, and the lid curl portion 23 This is because the lower end of the container main body 2 cannot be placed inside.

Next, the main part of the present invention will be described.
As shown in FIG. 4, the container body 2 is provided with two laterally oriented slits 18, 18 on the exposed portion 12b of the peripheral wall portion 12 so as to face each other. That is, these slits 18 and 18 are respectively provided at the portions of the exposed portion 12b that face each other, and are cut so as to penetrate the peripheral wall portion 12 inward and outward.

Each slit 18 is composed of a main slit portion 18a extending along the circumferential direction of the peripheral wall portion 12 and slit end portions 18b and 18b which are connected upward from both ends of the main slit portion 18a.

On the other hand, as shown in FIG. 5, the long flat member 4 includes a substantially rectangular long flat portion 31 and insertion piece portions 36 and 36 extending outward from both longitudinal ends of the long flat portion 31, respectively. It consists of

The long flat part 31 includes a main stacking part 32 having a length substantially equal to the outer diameter of the lid body 3, and side flat parts 33, 33 provided on both sides in the longitudinal direction of the main stacking part 32. The main stacking portion 32 and the side flat portions 33, 33 are connected to each other through folding lines 34, 34 provided in the width direction (direction orthogonal to the longitudinal direction).

Further, the main stacking portion 32 of the long flat portion 31 is formed with an easy-cutting portion 35 including two perforations parallel to each other in the width direction. The easy-cutting portion 35 can be relatively easily cut by the perforations, and the long flat portion 31 (long flat member 4) can be divided in the longitudinal direction by the cutting (see FIG. 7).

Here, as will be described later, the long flat member 4 is provided on the upper surface of the main stacking section 32 arranged on the lid 3 of the lower paper container 1 when stacking the plurality of paper containers 1 on the upper side. The container body 2 of the paper container 1 is placed. Therefore, the main stacking portion 32 of the long flat member 4 is formed with a width dimension capable of stably supporting the paper container 1 placed on the upper surface thereof. Specifically, the width of the main stacking portion 32 is preferably in the range of 1/4 to 1/2 of the outer diameter of the lid body 3. The side flat portion 33 is also formed with the same width as the main stacking portion 32.

The insertion piece portion 36 of the long flat member 4 is formed in a substantially trapezoidal shape, and is provided so as to be inserted into the slit 18 of the container body 2 described above. That is, the length of the insertion piece portion 36 in the width direction is slightly shorter than the length of the slit 18 in the circumferential direction.

The insertion piece portion 36 includes a coupling portion 41 that is coupled to the side flat portion 33, an insertion upper portion 43 that is coupled to the coupling portion 41 through a folding curve 42, and the insertion upper portion 43. It is the structure provided with the insertion lower part 44 extended to the side flat part 33 side, and this insertion lower part 44 is provided in the inside of the coupling part 41 through the notch line 46.

The insertion piece portion 36 is inserted into the slit 18 of the container body 2 from above and folded back along the folding line 42 (see FIG. 6) so that the insertion upper portion 43 is arranged above the slit 18. At the same time, the lower insertion portion 44 is arranged below the slit 18 (see FIG. 2). As a result, the insertion piece portion 36 cannot be easily released from the state of being inserted into the slit 18, and can be stably held in this state.

In such a long flat member 4, in the closed state where the opening 14 of the container body 2 is closed by the lid body 3, the insertion piece portions 36 at both ends are inserted into the slits 18 of the container body 2 via the lid body 3. It is installed by inserting each into.

That is, as shown in FIG. 4, the long flat member 4 is bent at the folding curves 34, 34 of the long flat portion 31 to have an inverted U shape, and the main stacking portion 32 is placed on the zenith portion 21 of the lid body 3 in the closed state. The insertion piece portions 36, 36 at both ends are inserted into the slits 18, 18 of the container body 2 from the outside of the peripheral wall portion 12 (see FIGS. 1 and 3). At this time, since the slit 18 of the container body 2 has the form of the main slit portion 18a and the slit end portions 18b, 18b as described above, the insertion piece portion 36 can be inserted relatively easily. ..

Then, after the insertion piece portion 36 is inserted into the slit 18, the insertion upper portion 43 and the insertion lower portion 44 are folded back along the folding curve 42 (see FIG. 6), so that the container body 2 is Inside the peripheral wall 12, the insertion upper part 43 is arranged above the slit 18 and the insertion lower part 44 is arranged below the slit 18. This makes it difficult for the insertion piece 36 to come off the slit 18.

In this way, the insertion piece portions 36 at both ends are attached to the slits 18, 18 of the container body 2, so that the long flat member 4 holds the lid body 3 and the container body 2 in the lid closed state. Then, the long flat material 4 is held in a state in which the main stacking portion 32 is arranged on the zenith portion 21 of the lid body 3. Here, as described above, the paper container 1 of this embodiment has the long flat member 4 attached with the lid 3 and the container body 2 closed.

When stacking a plurality of the paper containers 1 vertically, as shown in FIGS. 7 and 8, the main stacking portion 32 of the long flat material 4 is arranged on the lid 3 of the lower paper container 1. Therefore, the lower end of the upper paper container 1 (the body curl portion 13 of the container body 2) is placed on the upper surface of the main stacking portion 32. As a result, the stability in stacking is improved, and thus it is possible to prevent the plurality of paper containers 1 stacked vertically from collapsing. Further, when a plurality of products are stacked on display shelves or the like, it is easy for the customer to pick up once and then restore the original stacked state.

Further, since the side flat portions 33, 33 of the long flat member 4 are arranged along the vertical direction (axial direction) of the container body 2 in the paper container 1, one side flat portion 33 is used as the lower surface. It is also possible to place it. That is, when it is placed horizontally on the display shelf W or the like, as shown in FIG. 9, the paper container 1 is placed on the shelf of the display shelf with one side flat portion 33 as the lower surface. In this state of being horizontally placed, since the flat side flat portion 33 is placed on the shelf, the paper container 1 can be stably held without rolling to the left and right, and the display can be varied. It will be possible.

Further, as shown in FIG. 10, the paper container 1 can be easily divided by cutting the long flat material 4 with perforations as a mark of a portion where the easy-to-cut portion 35 is broken. As a result, in the paper container 1, it is difficult for the long flat member 4 to separate the insertion piece portions 36, 36 at both ends from the slits 18, 18 of the container body 2, and the lid closed state between the lid body 3 and the container body 2 is stabilized. In addition to being able to be held, the long flat member 4 can be easily divided by cutting the easy-cutting portion 35, and the lid 3 can be opened and closed. In addition, the easy-cutting portion 35 has a function of guaranteeing the sealed state of the paper container 1, and has an advantage of improving the quality of the product. For this reason, in such a paper-made container 1, there is an opening/tampering prevention characteristic that once the long flat member 4 is cut and opened, it cannot be returned to its original state. The long flat member 4 also has a function as a handle.

Further, the long flat member 4 is composed of the substantially rectangular long flat portion 31 and the insertion piece portions 36, 36 as described above, and can be formed by cutting a sheet of paper into a desired shape. .. As described above, since the long flat member 4 has a simpler shape than the above-described conventional lower end protruding portion, pad, and stacking parts, the cost required for manufacturing can be reduced.

Further, as described above, the paper container 1 is difficult to remove when the insertion piece portions 36, 36 of the long flat member 4 are inserted into the slits 18, 18 of the container body 2, respectively. No sticker attached to the main body 2 is required. Therefore, there is an advantage that the cost required for this sticker can be reduced, and there is also an advantage that there is no trouble of sticking and peeling the sticker. Also, there is no loss due to sticking mistakes on the stickers. Furthermore, with the insertion piece portion 36 inserted in the slit 18, gluing is not necessary.

Besides the above-described embodiment, the shape and the like of the paper container can be appropriately changed. For example, in the embodiment, the lid curl portion 23 is provided on the lid body 3 and the main body curl portion 13 is provided on the container body 2. However, instead of these curl portions, the upper end of the fitting peripheral portion of the lid body is lowered. It is also possible to provide a folded-back portion formed by folding-back and a folded-back portion formed by folding the lower end of the peripheral wall portion of the container body upward. Even with this configuration, the same operational effects as those of the above-described embodiment can be obtained.

Further, even in the long flat member 4, the shapes of the long flat portion 31 and the insertion piece portion 36 can be appropriately changed. For example, in the long flat portion, the main stacking portion may have a shape in which both side portions have a wide width and a central portion has a narrow width. With this configuration, since other paper containers are stacked on both sides of the main stacking unit, it is possible to stack more stably.

Further, the insertion piece portion may be, for example, substantially arrow-shaped. The insertion piece portion can be made difficult to remove by bending the left and right sides and inserting it into the slit of the container body, and then returning the left and right sides.

Further, as shown in FIG. 11, a paper container 50 as another example is proposed. In addition, about the element common to the structure described so far, the same code|symbol is attached|subjected and shown and demonstrated.

As shown in FIG. 11(A), a paper container 50 is a rectangular parallelepiped (polyhedral) container body 52 and a rectangular lid body formed on a part of an upper edge of the container body 52. 53, and the container main body 52 and the lid 53 have an integrated structure. Further, one slit 18 is formed in the left-right direction at the lower edge of the container body 52. On the other hand, at the tip of the lid 53, one insertion piece portion 36 is formed in series, and the insertion piece portion 36 can be inserted into the inside of the container body 52 via the slit 18. Has become. The easy-cutting portion 35 is provided near the insertion piece portion 36.

As shown in FIG. 11B, the insertion piece 36 is inserted into the inside of the container main body 52 through the slit 18 and protrudes upward (one side insertion). An insertion part) 43 and an insertion lower part (an other-side insertion part) 44 protruding downward.

In such a configuration, when the insertion piece portion 36 is inserted into the inside of the container body 52, the insertion upper portion 43 contacts the side wall surface portion 521 of the container body 52, and the insertion lower portion 44 of the container body 52. It contacts the bottom wall surface portion 522. In this way, when the slit 18 is formed on the corner side portion including the side wall surface portion 521 and the bottom wall surface portion 522, the insertion piece portion 36 is sandwiched between the both wall surface portions 521 and 522, and the insertion upper portion is formed. The insertion piece portion 36 is less likely to come off from the slit 18 by the 43 and the insertion lower portion 44 being pressed against each other by the wall surface portions 521 and 522. This eliminates the need for a seal for fastening the lid 53 to the container body 52.

Further, as shown in FIG. 12, a prismatic paper container 60 according to another example is proposed. In such a configuration, the peripheral wall portion of the container body 62 has a double structure, and has an outer wall 63a and an inner wall 63b.

The slit 18 is formed on the outer wall 63a, and the removal opening 64 is formed on the inner wall 63b in such a size that the slit 18 faces.

In such a configuration, the insertion piece portion 36 formed at the tip end portion of the strip-shaped long flat material 70 is in contact with the outer wall 63a while being inserted into the inside of the container body 62 via the slit 18. The upper insertion portion 43 and the lower insertion portion 44 can be touched via the opening 64 for removal. Therefore, by setting the bent portion of the insertion piece portion 36 to the original state, the engagement state between the insertion piece portion 36 and the peripheral edge of the slit 18 is released, and the insertion piece portion 36 is easily removed from the slit 18. It is possible to pull it out.

The paper containers 50 and 60 as another example described above may have a structure in which the slit 18 is formed in the lid 53 and the insertion piece portion 36 is formed in the container body 52.
