However, in such a container with a lid, the seal cylinder portion is fitted to the inner peripheral surface of the accommodating portion with the lid attached to the container body, and the lower end of the seal cylinder portion is from the upper end opening of the accommodating portion. Because it is located below, it was not possible to attach a sealing member such as a film to seal the upper end opening to the accommodating portion. On the other hand, there is a demand for improving the sealing property at the time of distribution and display.

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a container with a lid having improved sealing property at the time of distribution or display.

The present invention employs the following means to solve the above problems. That is, the container with a lid of the present invention includes a bottomed tubular container body for accommodating the contents, a lid that is detachably attached to the container body and closes the upper end opening of the container body, and the above. A sealing member attached to the container body to seal the upper end opening is provided, and the container body intersects a bottomed tubular accommodating portion in which the contents are accommodating and the accommodating portion with the container shaft. It has a mounted cylinder portion that surrounds from the outside, a flange portion that connects the accommodating portion and the mounted cylinder portion, and to which the sealing member is attached, and the lid is inside the upper end opening of the accommodating portion. It has a seal cylinder portion that can be fitted to and a mounting cylinder portion that is mounted on the mounted cylinder portion, and the mounting cylinder portion is undercut fitted to the fitting protrusion of the mounted cylinder portion. The container has a first locking portion and a second locking portion that is located above the first locking portion and can be locked from below to the locked portion of the mounted cylinder portion. The container body and the lid are restricted from relatively close to each other in the vertical direction between the main body and the lid, and the first locking portion is undercut fitted to the fitting protrusion. In addition, a holding means for holding the state in which the second locking portion is located above the locked portion is provided, and the first locking portion is separated downward from the fitting protrusion. In a state where the second locking portion is locked to the locked portion from below, the seal cylinder portion is fitted in the upper end opening of the accommodating portion, and the mounted cylinder portion is fitted with the second locking portion. 2 An introduction groove portion for introducing the locking portion is formed, and the introduction groove portion extends downward toward one direction in the circumferential direction around the container axis, and the first introduction portion and the first introduction portion. It is characterized by having a second introduction portion which is connected to the lower end of the introduction portion and extends in the one direction in the circumferential direction .

In the present invention, for example, in the state of distribution or display, since the seal cylinder portion is not fitted in the upper end opening of the accommodating portion, the upper end opening of the accommodating portion can be sealed by the seal member. At this time, since the first locking portion is undercut fitted to the fitting protrusion of the mounted cylinder portion, the lid body is prevented from being easily detached from the container body, and the holding means is used as the container body. It is possible to suppress the relative movement of the lid and the lid in the vertical direction.
Further, in a state where the second locking portion is locked to the locked portion from below after the seal member is peeled off, the seal cylinder portion fits in the upper end opening of the accommodating portion, so that the container body is sealed. can. Therefore, the container body can be resealed when the contents are taken out in a plurality of times. At this time, although the first locking portion is not fitted to the fitting protrusion, the lid is easily disengaged from the container body because the second locking portion and the locked portion are locked. It suppresses that.
As a result, it is possible to maintain the sealing property after peeling of the sealing member and improve the sealing property at the time of distribution and display.

Further, in the present invention, the holding means may include the locked portion and the second locked portion, and the second locked portion may be arranged on the upper surface of the locked portion.
In the present invention, when the second locking portion abuts on the upper surface of the locked portion, an unexpected external force such as a drop impact or an external force such as a load when containers with a lid are stacked and displayed and stored is applied to the lid. Even if it is added to the container body, it is possible to prevent the lid body from moving downward with respect to the container body. As a result, it is possible to prevent the seal cylinder portion from deforming or making a judgment on the seal member.

According to the container with a lid according to the present invention, for example, the upper end opening of the accommodating portion is sealed by the sealing member in the state of distribution or display, and the second locking portion is locked after the sealing member is peeled off. Since the seal cylinder portion is fitted in the upper end opening of the accommodating portion in a state of being locked to the portion from below, the container body can be resealed. As a result, it is possible to maintain the sealing property after peeling of the sealing member and improve the sealing property at the time of distribution and display.

It is divided into the guide unit 25B and the guide unit 25B. One end in the circumferential direction of the locked portion 25A is connected to the other end in the circumferential direction of the guide portion 25B, and the lower surface of the other end in the circumferential direction of the locked portion 25A is in the other direction in the circumferential direction. It is inclined upward as it goes toward it. Further, the upper surface of one end portion in the circumferential direction of the guide portion 25B is inclined downward toward one end portion in the circumferential direction.

As shown in FIGS. 1 and 2, the fitting protrusion 23 is slightly inclined downward toward the inside in the radial direction, and the outer peripheral edge of the fitting protrusion 23 is a lower tubular portion 22. It is located on the outer side in the radial direction. Further, the fitting protrusion 23 is located slightly below the step portion 14 of the accommodating portion 11.

As shown in FIGS. 1 and 3, the lid 3 includes a circular top wall portion 31 in a plan view, a cylindrical seal cylinder portion 32 connected to the outer peripheral edge of the top wall portion 31, and a seal cylinder. An annular connecting portion 33 in a plan view, which is connected to the upper end edge of the portion 32, and a cylindrical mounting cylinder portion 34 connected to the outer peripheral edge of the annular connecting portion 33 are provided. The top wall portion 31, the seal cylinder portion 32, the annular connection portion 33, and the mounting cylinder portion 34 are arranged coaxially with the container shaft O.
The top wall portion 31 is located above the seal member 4.
The seal cylinder portion 32 is inclined so as to be radially outward from the lower end toward the upper side. The tilt angle of the seal cylinder portion 32 is slightly larger than the tilt angle of the accommodating portion 11. Further, the radial position of the upper end of the seal cylinder portion 32 is equivalent to the radial position of the upper end of the accommodating portion 11. At the intermediate portion in the vertical direction of the seal cylinder portion 32, a seal protrusion 32A projecting outward in the radial direction is formed over the entire circumference.
The radial position of the outer peripheral edge of the annular connecting portion 33 is the same as the outer peripheral edge of the lower tubular portion 22.

The mounting cylinder portion 34 has a cylindrical upper portion 41 connected to the outer peripheral edge of the annular connection portion 33, and a cylindrical lower portion 42 connected to the lower end of the upper portion 41. The upper portion 41 and the lower portion 42 are arranged coaxially with the container shaft O.
The vertical position of the lower end of the upper portion 41 is the same as the upper surface of the lower cylinder portion 22, and the guide protrusion 41A protruding inward in the radial direction is circumferentially located at the lower end portion of the upper portion 41. A plurality of (four in this embodiment) are formed at intervals.

The circumferential spacing of the guide protrusions 41A is equivalent to the circumferential spacing of the upper end opening of the introduction groove 22A. Further, the upper surface of the guide protrusion 41A is inclined downward toward the inside in the radial direction, and the inner surface in the radial direction of the guide protrusion 41A extends in the vertical direction, and the guide protrusion 41A The lower surface of the is extending in the radial direction. The lower surface of the guide protrusion 41A is in contact with the upper surface of the lower tubular portion 22. The radial inner end of the guide protrusion 41A is located slightly radially outside the lower end of the upper cylinder portion 21, and the guide protrusion 41A is located, for example, as shown in FIGS. 4 to 6, for example. It is in contact with the upper surface of the lower cylinder portion 22 or the upper surface of the first hooking protrusion 22B.

Further, as shown in FIGS. 1 and 3, the recessed portions 41B that are recessed inward in the radial direction are continuously arranged side by side in the circumferential direction on the upper portion 41. The depressed portion 41B is formed over the entire length of the upper portion 41 in the vertical direction, and suppresses elastic deformation of the upper portion 41 in the radial direction. The radial position of the inner end of the recessed portion 41B is the same as the radial position of the outer peripheral surface of the lower tubular portion 22. Further, the length of the upper portion 41 in the vertical direction is equivalent to the length of the upper cylinder portion 21 and the lower cylinder portion 22 in the vertical direction.

At the lower end of the lower portion 42, a plurality of locking protrusions (first locking portions) 42A protruding inward in the radial direction are formed at intervals in the circumferential direction. The locking protrusion 42A extends radially and is undercut fitted to the fitting protrusion 23.

As the sealing member 4, for example, a heat-sealing resin sheet in which a synthetic resin film is coated with a metal film such as aluminum, a resin film, a paper sheet, or the like is preferably used. Further, when an aluminum laminated film having a layer of an aluminum film having a barrier property is used as the sealing member 4, the contents can be suitably stored. Further, the seal member 4 is attached to the flange portion 12 of the container body 2 by various means such as adhesion, heat welding, ultrasonic welding and the like.

Next, a method of using the container 1 with a lid having the above configuration will be described.
First, in a state where the seal member 4 is attached to the flange portion 12 of the container body 2 at the time of distribution or display, the guide protrusion 41A of the lid 3 is a lower cylinder including the locked portion 25A of the container body 2. The locking protrusion 42A is in contact with the upper surface of the portion 22 or the upper surface of the first hooking protrusion 22B, and the locking protrusion 42A is undercut fitted to the fitting protrusion 23 of the lower tubular portion 22.

Therefore, as shown in the guide protrusion 41A shown by the solid line in FIG. 4 and FIG. 5, when the lidded container 1 is dropped while the guide protrusion 41A is in contact with the upper surface of the lower cylinder portion 22. Even if an unexpected force such as an impact or a load when the containers 1 with a lid are stacked and displayed and stored is applied to the top wall portion 31 of the lid 3, the lid 3 moves downward with respect to the container body 2. Movement is suppressed. Therefore, it is possible to prevent the seal member 4 from being deformed or broken by the seal cylinder portion 32, such as by unintentionally denting the seal member 4. Here, since the lower surface of the guide protrusion 41A is not inclined in the radial direction, it is difficult to get over the upper end of the lower cylinder portion 22.

Further, as shown in the guide protrusion 41A and FIG. 6 shown by the virtual line in FIG. 4, such an unexpected state is that the upper end opening of the introduction groove 22A and the guide protrusion 41A are aligned in the circumferential direction. Even if the force or load of the above is applied to the top wall portion 31, the guide protrusion 41A is in contact with the first hook protrusion 22B from above, so that the guide protrusion 41A enters the introduction groove portion 22A and the lid 3 is inserted. The movement downward with respect to the container body 2 is suppressed. Therefore, similarly to the above, it is possible to prevent the seal member 4 from being unintentionally deformed or broken. This eliminates the need for the locking protrusion 42A to be undercut fitted to the fitting protrusion 23 in a state where the guide protrusion 41A is displaced from the upper end opening of the introduction groove 22A in the circumferential direction, and the lid 3 is placed in the container. The operation of attaching to the main body 2 becomes easy.

Then, in order to open the container 1 with a lid, first, the lid 3 is removed from the container body 2. When the lid 3 is moved upward with respect to the container body 2, the lower portion 42 in which the locking protrusion 42A undercut fitted to the fitting protrusion 23 is formed is elastically deformed outward in the radial direction. Then, the locking protrusion 42A gets over the fitting protrusion 23 upward. As a result, the lid 3 is removed from the container body 2. Then, the sealing member 4 is peeled off from the container body 2 and the container body 2 is opened. After that, the contents in the container body 2 are appropriately taken out.

Further, in order to reseal the container 1 with a lid, the guide protrusion 41A of the lid 3 and the upper end opening of the introduction groove 22A formed in the lower cylinder 22 of the container body 2 are provided in the circumferential direction. Align. When the lid 3 is pushed into the container body 2 in this state, the guide protrusion 41A gets over the first hook protrusion 22B and enters the introduction groove 22A. Then, when the lid 3 is rotated in one direction in the circumferential direction with respect to the container body 2, the guide protrusion 41A that has entered the introduction groove 22A enters the container body 2 along the first introduction portion 24A of the introduction groove 22A. On the other hand, it moves downward with respect to the container body 2 while moving in one direction in the circumferential direction, and then moves in one direction with respect to the container body 2 along the second introduction portion 24B. Then, the guide protrusion 41A gets over the second hook protrusion 22C in one direction in the circumferential direction, and within the second introduction portion 24B, one end portion of the second introduction portion 24B in the circumferential direction and the second hook protrusion 22C Positioned in the circumferential direction between. As a result, the guide protrusion 41A is locked to the locked portion 25A from below. Here, the user indicates that the guide protrusion 41A is firmly locked to the locked portion 25A by vibration or sound generated when the guide protrusion 41A gets over the second hook protrusion 22C. Can be recognized. At this time, the locking protrusion 42A is separated downward from the fitting protrusion 23.

Further, as the lid 3 moves downward with respect to the container body 2, the seal cylinder portion 32 enters into the upper end opening of the accommodating portion 11 and is fitted. Here, the seal protrusion 32A of the seal cylinder portion 32 is strongly in contact with the inner peripheral surface of the upper end opening of the accommodating portion 11. As a result, as shown in FIG. 7, the container body 2 is sealed by the lid 3. Here, the fitting state between the outer peripheral surface of the seal cylinder portion 32 and the inner peripheral surface of the accommodating portion 11 may be such that the contents in the container main body 2 do not flow out to the outside.
Even if an unexpected force is applied to the lid 3 in this state, the guide protrusion 41A cannot get over the lower cylinder portion 22 in the vertical direction, and the guide protrusion 41A is the second introduction portion 24B. Since one end portion in the circumferential direction and the second hooking protrusion 22C are positioned in the circumferential direction, it is possible to prevent the lid body 3 from being removed from the container body 2 due to an unexpected force applied to the lid body 3. ..

In order to reopen the container 1 with a lid, the lid 3 is rotated in the other direction in the circumferential direction with respect to the container body 2. As a result, the guide protrusion 41A gets over the second hook protrusion 22C, moves in the other direction in the circumferential direction with respect to the container main body 2 along the second introduction portion 24B, and moves along the first introduction portion 24A to the container. It moves upward while moving in the other direction in the circumferential direction with respect to the main body 2, gets over the first hooking protrusion 22B, and exits from the introduction groove portion 22A. In this way, the lid 3 is removed from the container body 2 again. After that, the lid 3 is attached to the container body 2 in the same manner as described above. As a result, the container body 2 can be sealed even when the contents are taken out in a plurality of times.
As described above, the container 1 with a lid is used.

As described above, according to the container 1 with a lid according to the present embodiment, for example, in the state of distribution or display, the lower end of the seal cylinder portion 32 is located above the upper end opening 2A of the accommodating portion 11, so that the seal is sealed. The member 4 can seal the upper end opening 2A of the accommodating portion 11. Here, by using an appropriate material as the sealing member 4, the contents in the container body 2 can be suitably stored. Further, in a state where the guide protrusion 41A is locked to the locked portion 25A from below after the seal member 4 is peeled off, the seal cylinder portion 32 fits into the inner peripheral surface of the accommodating portion 11 to seal the container body 2. Since it is stopped, the sealing property after peeling of the sealing member 4 can be maintained. As a result, the sealing property of the sealing member 4 after peeling can be maintained, and the sealing property at the time of distribution and display can be improved.
Further, since the guide protrusion 41A is in contact with the upper surface of the locked portion 25A to restrict the lid 3 from moving downward with respect to the container body 2, when the container 1 with a lid is dropped. Even if an unexpected force such as an impact of the above or an external force such as a load when the containers with lids 1 are stacked is applied to the lid body 3, the seal cylinder portion 32 is located above the seal member 4. Can be held securely. As a result, it is possible to prevent the seal member 4 from being unintentionally deformed or broken by the seal cylinder portion 32.

Next, a second embodiment of the container with a lid according to the present invention will be described with reference to the drawings. The embodiment described here has the same basic configuration as the above-described embodiment, and has another element added to the above-mentioned embodiment. Therefore, in the following drawings, the same components as those in the above drawings are designated by the same reference numerals, and this description will be omitted.

As shown in FIGS. 8 to 10, the container 100 with a lid according to the present embodiment includes a container body 101 and a lid 102, and the lower cylinder portion 104 of the mounted cylinder portion 103 in the container main body 101 has a lid-mounted container 100. , The first hooking protrusion 22B is not formed. Instead, a plurality of hook recessed portions 106A (four in the present embodiment) are formed on the upper portion 106 of the mounting cylinder portion 105 in the lid body 102 at intervals in the circumferential direction. The hook recessed portion 106A is provided in place of a part (four) of the recessed portion 41B, and is formed so as to be displaced from the guide protrusion portion 41A in the circumferential direction. The amount of the hook recessed portion 106A inwardly depressed in the radial direction is larger than that of the recessed portion 41B. The radial inner end of the hook recessed portion 106A is in contact with the upper surface of the lower tubular portion 104, but is located radially outside the radial inner end of the guide protrusion 41A.

The method of using the container with a lid 100 as described above is the same as the method of using the container with a lid 1 according to the first embodiment described above.
When the seal member 4 is attached to the flange portion 12 of the container body 101 during distribution or display, the guide protrusion 41A or the hooking recessed portion 106A of the lid 102 is the upper surface of the lower cylinder portion 104 of the container body 101. Is in contact with.
Therefore, as shown in FIG. 11, even if an unexpected force is applied to the lid 102 in a state where the guide protrusion 41A is in contact with the upper surface of the locked portion 25A, the lid 102 is downward with respect to the container body 101. To prevent the seal member 4 from being unintentionally deformed or broken.
Further, as shown in FIG. 12, even if such an unexpected force is applied to the lid 102 in a state where the upper end opening of the introduction groove 22A and the guide protrusion 41A are aligned in the circumferential direction, the hooked recessed portion 106A is formed. Since it is in contact with the upper surface of the lower cylinder portion 104, the guide protrusion 41A enters the introduction groove portion 22A, the lid 102 moves downward with respect to the container body 101, and the seal member 4 is unintentionally deformed. Suppresses breaking.

After that, when the lid 102 is attached to the container body 101 in order to reseal the container 100 with a lid after the sealing member 4 is peeled off, the guide protrusion 41A is provided in the circumferential direction with the upper end opening of the introduction groove 22A. The lid 102 is moved downward with respect to the container body 101 in the state of being aligned with. Here, the hook recessed portion 106A is in contact with the upper surface of the lower tubular portion 104, but the radial inner end of the hook recessed portion 106A is located radially outside the radial inner end of the guide protrusion 41A. Therefore, it does not prevent the lid 102 from moving downward with respect to the container body 101. Hereinafter, as shown in FIG. 13, the lidded container 100 is resealed by the same procedure as that of the lidded container 1 according to the first embodiment.
As described above, the container with a lid 100 is used.

The container with a lid 100 configured as described above also has the same effect as the container with a lid 1 according to the first embodiment described above.

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, four guide protrusions are formed at intervals in the circumferential direction, but at least one may be formed, and two, three, or five or more may be formed. The same applies to the introduction groove portion. Further, when only one introduction groove portion is formed, the introduction groove portion may have a spiral shape like a screw groove.
The introduction groove portion has a first introduction portion that is inclined downward toward one direction in the circumferential direction and a second introduction portion that extends in the circumferential direction, and the first introduction portion is in the vertical direction. The first locking portion, such as a structure extending in the circumferential direction or a structure having only a first introduction portion that inclines downward toward one direction in the circumferential direction, allows the lid body to be circumferentially oriented with respect to the container body. The lid may be detachable from the container body by rotating the lid.
An introduction groove is formed in the mounted cylinder portion, and a guide protrusion is formed in the mounting cylinder. However, a guide protrusion is formed in the mounted cylinder and a guide protrusion is provided in the mounting cylinder. It may be formed. Further, the combination of the introduction groove portion and the guide protrusion portion is not limited as long as the lid body can be attached to and detached from the container body by rotating.
The second locking portion and the locked portion are locked by rotating the lid in one direction in the circumferential direction with respect to the container body and allowing the guide protrusion to enter the introduction groove. May be configured to lock without rotating with respect to the container body.
A plurality of locking protrusions are formed at intervals in the circumferential direction, but at least one may be formed.
The holding means is composed of a guide protrusion portion and a second locking portion, but may be composed of a portion different from the guide protrusion portion. For example, the seal member and the seal cylinder portion may function as holding means. At this time, even if an unintended external force is applied to the lid and the seal cylinder portion abuts on the seal member in a state where the first locking portion is undercut fitted to the fitting protrusion, the seal member is elastically deformed. By resisting the force applied to the seal member by the seal cylinder portion or the like, it is possible to prevent the seal member from being broken.
The structure of the container body according to the first embodiment and the structure of the lid body according to the second embodiment may be combined. For example, in the first embodiment, the structure of the lid may be configured to have a hooked recessed portion as in the case of the lid in the second embodiment. Further, the container body of the first embodiment may be configured not to be provided with the first hooking protrusion, and the lid of the second embodiment may be configured not to be provided with the hooking recessed portion. good. Further, the shape may be other than the first hooking protrusion and the hooking recessed portion.
Although it is described as "cylindrical" in the description of each constituent member, it may have another shape as appropriate, such as an elliptical shape, another polygonal shape such as a triangular shape or a rectangular shape.

According to the present invention, industrial applicability is recognized for a container with a lid having improved sealing properties during distribution and display.

1,100 container, 2,101 container body, 2A upper end opening, 3,102 lid, 4 seal member, 11 accommodating part, 13,103 mounted cylinder part, 23 fitting protrusion, 25A locked part ( Holding means), 32 seal cylinder part, 34,105 mounting cylinder part, 41A guide protrusion (second locking part, holding means), 42A locking protrusion (first locking part)
