Description

  The present invention relates to a container with a lid formed of a paper sheet whose main material is paper.

  Conventionally, resin-based containers have been used exclusively for packaging granular gums, supplements, chocolates and the like. This resin-based container is used because it is excellent in terms of functions such as initial sealability, recloseability, and water vapor barrier properties.

  In addition, this type of container is configured so that the opening of the container body can be repeatedly opened and closed with a lid. Generally, both a container main body and a lid (for example, refer to Patent Document 1) are connected and integrated after being molded with resin.

  The lid includes a disk-shaped upper lid, a tear ring that hangs from the periphery thereof, a fixing ring that hangs from below the tear ring, and a hinge that connects the upper lid to the fixing ring. The tear ring functions as a pilfer proof portion, and is connected to the upper lid and the fixing ring via an annular thin portion. The hinge is provided so as to cross the tear ring in the vertical direction. In addition, an annular protrusion that fits into an annular groove formed on the outer peripheral surface of the container body is formed on the inner peripheral surface of the upper lid, and a thin annular hanging wall is provided on the ceiling surface of the upper lid.

  The lid is put on a container main body filled with contents such as granular gum, and the fixing ring is fitted around the opening of the container main body to be integrated with the container main body. Moreover, the annular protrusion of the upper lid fits into the annular groove of the lid body to seal the inside of the container body.

  The container can be opened by the user tearing and removing the tear ring from the lid, and the container body is opened by opening the lid so that the annular projection on the upper lid is detached from the annular groove of the lid body. Is released. The lids are connected by hinges and try to close the opening of the container body by the elastic force of the hinges, but the annular thin part abuts the opening edge of the container body and prevents the lid body from returning to the closed position. The lid is held in the open state. As a result, the user can easily take out the contents from the container body. After the user takes out the contents, if the lid is put on the container body and pressed, the annular protrusion of the upper lid fits into the annular groove of the lid body, and the container body is sealed again.

  Moreover, a paper cup (for example, refer patent document 2) may be used for packaging of the granular content. In this case, after filling the paper cup with granular contents, the paper cup is sealed by adhering a lid sheet such as an aluminum foil to the opening edge of the paper cup. The user can peel off the lid sheet from the opening edge of the paper cup and take out the contents from the container body.

  The best mode of the present invention will be described below with reference to the drawings.

<First Embodiment>
1 is a perspective view showing a first embodiment of a container with a lid according to the present invention, FIG. 2 is a longitudinal sectional view of FIG. 1, FIG. 3 is a developed view showing a blank of the lid of FIG. 1, and FIG. 5 is a longitudinal sectional view showing the opened state, FIG. 5 is a sectional view showing a state where the lid of FIG. 1 is resealed, and FIG. 6 is a developed plan view of the inner seal part of FIG. 7A is a cross-sectional view taken along the line VII-VII in FIG. 6, and FIG. 7B is a similar cross-sectional view at the time of opening.

  As shown in FIGS. 1 and 2, the container with a lid includes a container body 1 having an opening on the upper surface and a lid body 2 that covers the opening of the container body 1.

  The container body 1 is formed in a cylindrical shape by winding a paper sheet mainly made of paper into a cylindrical shape and overlapping and bonding both ends thereof. In addition, it can be formed by a spiral tube obtained by winding a paper sheet in a spiral shape. The container body 1 can also be formed in a tapered or inversely tapered cylindrical shape.

  The lid 2 includes a peripheral surface portion 21 having an inwardly curled portion 21a formed at the upper end opening edge, and a top surface portion bonded to the lower portion of the inwardly curled portion 21a of the peripheral surface portion 21 by a bonding means such as an adhesive or hot melt. 22.

  The lid 2 is formed in a cylindrical shape by overlapping both ends with an adhesive allowance 23 and bonding them as in a blank 2A shown in FIG. Moreover, the cover body 2 is couple | bonded by the hinge 24 with the back side upper part of the container main body 1, as shown in FIG.1 and FIG.2. The hinge 24 is formed on the blank 2A constituting the lid 2 so as to be bent. As shown in FIG. 4, when the lid 2 is opened, the hinge 24 bends, and even when the lid 2 is released, the open state of the lid 2 is maintained by the folding of the paper. It is possible to easily remove a.

  More specifically, as shown in FIG. 3, the hinge 24 is formed on the blank 2 </ b> A constituting the lid body 2 by being divided through a broken line 24 a. The broken line 24a is formed at the same time when the lid 2 is punched out from the paper sheet. The tip of the hinge 24 is bonded to the upper part on the back side of the container body 1 by an adhesive, ultrasonic bonding or heat sealing. Thus, since the hinge 24 is formed using a part of the lid body 2, it is not necessary to provide a separate hinge, and the lid body 2 can be prevented from being enlarged.

  As shown in FIG. 3, inverted V-shaped notches 25 and 25 are formed on both sides of the hinge 24, and the outsides of these notches 25a and 25a are formed into wide portions 26a and 26a having a width of 28 mm. Has been. On the outside of these wide portions 26a and 26a, narrow portions 26c and 26c having a width of 19 mm are formed via gentle curved portions 26b and 26b, respectively.

  One of these narrow portions 26c, 26c is provided with the above-mentioned bonding margin 23, and is formed by dividing the folding piece 27 on the blank 2A via a broken line 27a in the middle of the other longitudinal direction. . The folding piece 27 is separated from an engagement pressure contact piece 28 as an engaging portion via a separation line 28a, and further, the engagement pressure contact piece 28 is separated from an engagement adhesive piece 29 via a broken line 29a.

  The blank 2 </ b> A formed in this manner is overlapped at both ends with the bonding allowance 23 and bonded to form the cylindrical lid 2. Further, when the lid 2 is configured, after the folding piece 27 is folded to the inner peripheral side via the folding line 27a, the engagement pressure contact piece 28 as the engagement piece is folded in a mountain via the separation line 28a, The engagement adhesive piece 29 is valley-folded through the broken line 29a. When these folding pieces 27, the engagement pressure contact pieces 28, and the engagement adhesive pieces 29 are formed on the lid body 2, they become symmetrical positions on the side opposite to the hinge 24.

  As shown in FIG. 2, the inner surface of the engagement adhesive piece 29 is the outer peripheral surface of the upper portion of the container body 1 before the lid body 2 is opened, and is opposite to the position where it is connected to the hinge 24 of the container body 1. It is joined. The engagement pressure contact piece 28 is cut along the separation line 28a when the lid is opened, and remains in a state of being joined by the engagement adhesive piece 29 on the side opposite to the position where it is connected to the hinge 24 of the container body 1. Therefore, since the engagement pressure contact piece 28 is cut along the separation line 28a when the lid is opened, it can function as a pill fur proof. Further, since the engagement pressure contact piece 28 has a bending restoring force, the engagement pressure contact piece 28 acts to be in pressure contact with the inner surface of the peripheral surface portion 21 of the lid body 2 when the lid is closed.

  By the way, as the paper sheet, for example, one having the following layer structure can be used.

  In the layer configuration, the first layer is the surface side of the container body, and the last layer is the inner surface side of the container body. When a paper sheet is wound into a cylindrical shape and bonded at both ends, for example, the innermost layer and the outermost polyethylene resin layer of the paper sheet are used as a thermal adhesive.

  Polyethylene resin layer / paper layer / polyethylene resin layer, polyethylene terephthalate resin layer / paper layer / polyethylene resin layer, polyethylene resin layer / polyethylene terephthalate resin layer / paper layer / polyethylene resin layer, high density polyethylene resin layer (film) / polyethylene resin Layer / paper layer / polyethylene resin layer, foamed polyethylene resin layer / paper layer / polyethylene resin layer, polypropylene resin layer / paper layer / polypropylene resin layer, polyethylene resin layer / paper layer / polyester resin layer, polyester resin layer / paper layer / Polyester resin layer, polyethylene resin layer / paper layer / ethylene-acrylic acid copolymer layer / aluminum foil / polyethylene resin layer, polyethylene resin layer / paper layer / polyethylene layer / polyester layer / polyethylene resin layer, polyethylene resin layer / paper layer / Polyet Ren layer / polyester layer / polyethylene resin layer (film), polyethylene resin layer / paper layer / polyethylene layer / aluminum foil / biaxially stretched polyester layer / polyethylene resin layer, polyethylene resin layer / paper layer / polyethylene layer / deposited aluminum layer / Polyester layer / polyethylene resin layer, polyethylene resin layer / paper layer / polyethylene resin layer / silica vapor deposition layer / polyester layer / polyethylene resin layer (film), paper only, paper layer / polyethylene resin layer.

  The cylindrical upper end of the container body 1 is an opening of the container with a lid, while the bottom of the container body 1 is closed with a bottom lid 3. The bottom lid 3 is also formed into a disk shape from the paper sheet, and is attached to the lower end of the container body 1 by winding or the like.

  That is, as shown in FIG. 2, the bottom lid 3 is drawn so as to bend its outer peripheral edge downward, whereby the bottom lid 3 has a substantially “ko” shape whose sectional shape is opened downward in FIG. It is formed in a letter shape. The bent portion of the outer periphery of the bottom lid 3 is bonded so that the lower end of the container body 1 is wrapped from the outside, so that the yarn tail 4 of the container body 1 is formed.

  The lid 2 is formed in a cylindrical shape by punching or the like from a paper sheet similar to the paper sheet constituting the container body 1. As described above, since the lid 2 is formed mainly of paper together with the container main body 1, the lidded container is excellent in recyclability and light-shielding properties, and is excellent in environmental performance even when discarded.

  When the lid 2 is first opened from the container main body 1, the engagement pressure contact piece 28 is cut along the cut-off line 28a as shown in FIG. 4, and functions as a pill fur proof. Here, the engagement pressure contact piece 28 remains in a state of being joined via the engagement adhesive piece 29 on the side (symmetrical position) opposite to the position where it is coupled to the hinge 24 of the container body 1.

  On the other hand, when the lid body 2 is put on the container body 1 from above the opening, as shown in FIG. 2, the peripheral surface portion 21 and the top surface portion 22 of the lid body 2 are attached so that the upper portion of the container body 1 is covered from the outside. Is done. At this time, since the engagement pressure contact piece 28 has a bending restoring force, it is in pressure contact with the inner surface of the peripheral surface portion 21 of the lid body 2. Thereby, the lid body 2 is fixed to the container body 1 with a large engagement force, and the locking function (closing force) of the lid body 2 is enhanced. The lid 2 can be opened and closed repeatedly on the container body 1. Thereby, resealability is given to this container with a lid, and the preservability of the contents a stored in the container body 1 is improved. Further, since the engagement pressure contact piece 28 is accommodated in the peripheral surface portion 21 of the lid body 2 and is not exposed to the outside when the lid is closed, the appearance of the appearance is improved.

  Since the lid body 2 can be repeatedly opened and closed with respect to the container body 1, the engagement pressure contact piece 28 contacts the opening of the circumferential surface portion 21 of the lid body 2 every time the lid body 2 is opened and closed. Since the portion that comes into contact with the engagement pressure contact piece 28 is thickened with the folding piece 27, it is possible to prevent the peripheral surface portion 21 of the lid body 2 from being easily damaged by repeated opening and closing operations. .

  In addition, it is desirable to previously form a water vapor adsorption layer on the paper sheet forming the lid 2 by applying a paint containing a water vapor adsorbent by printing or the like. Thereby, the water vapor which permeate | transmits the cover 2 and the paper layer of the container main body 1 is adsorbed by the water vapor adsorption layer, and the contents a in the container main body 1 can be protected from moisture.

  As shown in FIG. 4, the lid 2 is coupled to the container body 1 by a hinge 24. The hinge 24 is formed on the blank 2A constituting the lid 2 so as to be freely bent. As shown in FIG. 4, when the lid 2 is opened, the hinge 24 bends, and even when the lid 2 is released, the open state of the lid 2 is maintained by the folding of the paper. It is possible to easily remove a.

  Further, on both sides of the hinge 24, cutout portions 25, 25 cut out in an inverted V shape are formed, and the cutout end portions 25a, 25a abut against the outer peripheral surface of the container body 1 when the lid is opened, and the state is maintained. By doing so, the lid body 2 is not naturally closed by the elastic force of the hinge 24, and the open state of the lid body 2 can be reliably held.

  As shown in FIG. 2, the inner side of the opening of the container body 1 closed by the lid 2 is sealed with the inner seal portion 5. The inner seal portion 5 is provided as necessary. By providing the inner seal portion 5, the initial sealing performance of the container body 1 is enhanced.

  As shown in FIG. 6, the inner seal portion 5 is formed in a disc shape so that the development plane thereof corresponds to the opening of the container body 1.

  As shown in FIG. 7A, the inner seal portion 5 is formed of a laminated body having at least two layers. The outer layer 5a has, for example, a laminated structure of a barrier film / olefin resin layer, and the inner layer 5b has, for example, a laminated structure of olefin resin layer / paper layer / olefin resin layer, and the olefin resin layers are welded together. Thus, the inner and outer two layers are overlapped.

  Moreover, as shown in FIG.6 and FIG.7 (A), the tearing part 6 is formed in the outer layer 5a by the cut lines 6a and 6b. These cut lines 6a and 6b are provided along two large and small circles, and an annular tearing portion 6 is formed between the two circles. In addition, a cut line 6 c that crosses the annular tearing part 6 is also provided, and a knob 7 is formed in the annular tearing part 6 by the cut line 6 c. These cut lines 6a, 6b, 6c are preferably formed in a perforated shape, but can also be formed as continuous lines.

  6 and 7A, the inner seal portion 5 is heat-sealed and bonded to the inner peripheral surface of the container body 1 by, for example, ultrasonic waves as a bonding margin 5a.

  When the inner seal portion 5 is opened, the knob 7 is torn along the cut line 6c with a finger or the like, and the knob 7 is pulled, so that the annular tear portion 6 becomes the inner seal as shown in FIG. It is excised from part 6. Thereby, the inner seal part 5 is opened.

  The container body 1, the lid body 2, and the inner seal portion 5 have desired contents in a desired layer such as an olefin resin layer, a paper layer, or a film of a paper sheet constituting them. It is displayed so as to be visible from the outside by printing or the like.

  The inner seal portion 5 may be joined to the container body 1 through an easy peel layer in which a knob portion is integrally formed, although not shown. In this case, the operability for opening the container can be improved by the inner seal portion 5 being joined to the container body 1 via the easy peel layer.

  Next, the operation of the lidded container having the above configuration will be described.

  The container main body 1 shown in FIG.1 and FIG.2 is prepared, and the blank 2A of the cover body 2 shown in FIG. 3 and the blank of the inner seal part 5 shown in FIG. 6 are prepared.

  As shown in FIG. 2, first, after the container body 1 is filled with the content a such as granular gum, the opening is closed by the inner seal portion 5. The inner seal portion 5 is inserted into the container body 1 from its opening, and after the outer bonding allowance 5a is pressed against the inner surface of the container body 1 from the two-dot chain line shown in FIG. 6 and FIG. It is adhered to the inner surface of the container body 1 by a seal or the like.

  Next, the lid 2 is placed over the opening of the container body 1, and the inner surface of the engagement adhesive piece 29 is the outer peripheral surface of the upper part of the container body 1, and is joined to the opposite side of the position where it is coupled to the hinge 24 of the container body 1. Has been. At the same time, the hinge 24 formed on the lid 2 is attached to the upper part on the back side of the container body 1 with an adhesive or the like.

  Thereby, the assembly of the container with a lid is completed.

  When taking out the contents a, the purchaser or the like of the container with the lid puts his / her finger on the narrow portion 26c in the peripheral surface portion 21 of the lid body 2 in the state shown in FIGS. Lift above the opening. Then, the lid body 2 opens with the hinge 24 as the center, and at the same time, the engagement pressure contact piece 28 is separated along the separation line 28a and is engaged with the engagement adhesive piece on the opposite side of the position where it is connected to the hinge 24 of the container body 1. 29 remains in a joined state.

  At this time, since the engagement pressure contact piece 28 functions as a pilfer proof means, the purchaser or the like confirms the state of the engagement pressure contact piece 28 to determine whether or not the content a in the lidded container is normal. Can be determined.

  When the purchaser or the like lifts the lid body 2 above the opening of the container body 1, as shown in FIG. 3, the purchaser bends on the fold line 24 a of the hinge 24, and the opening of the container body 1 is opened. At the same time, a crease is attached to the fold line 24 a of the hinge 24.

  When the purchaser or the like removes his / her finger from the lid body 2 to release the lid body 2, the lid body 2 is held open as shown in FIG. 4 due to the folding of the broken line 24 a.

  Therefore, the purchaser or the like tears the knob 7 along the cut line 6c by hooking his / her finger on the knob 7 shown in FIG. 7A, and further pulls the knob 7 so that FIG. The annular tearing part 6 is cut out from the inner seal part 5 as shown in FIG. As a result, the inner seal portion 5 is opened as shown in FIG. 4, and the purchaser or the like can take out the contents a from the container body 1.

  Thereafter, when the purchaser or the like presses the lid 2 against the opening side of the container body 1 with a finger, the peripheral surface portion 21 and the top surface portion 22 of the lid body 2 are covered on the upper portion of the container body 1 as shown in FIG. At this time, since the engagement pressure contact piece 28 has a bending restoring force, it is in pressure contact with the inner surface of the peripheral surface portion 21 of the lid 2. Thereby, the cover body 2 is restrained in the closed position with respect to the container main body 1. Thereby, the cover body 2 maintains the closed state until it is opened again by the purchaser or the like.

  When a purchaser or the like tries to take out the contents a from the container body 1 again, the lid body 2 may be lifted as shown in FIG. 4, and the lifted lid body 2 is folded along a broken line 24a as shown in FIG. Hold open with scissors. For this reason, a purchaser etc. can take out the content a from the container main body 1 easily. Here, since the engagement pressure contact piece 28 has a bending restoring force, the engagement pressure contact piece 28 is inclined outward at a predetermined angle in the open state of the lid body 2.

  After the contents a are taken out, the lid body 2 may be pressed against the opening side of the container body 1, and the peripheral surface portion 21 and the top surface portion 22 of the lid body 2 are connected to the container body 1 as shown in FIG. Deposited on top. At that time, since the engagement pressure contact piece 28 has a bending restoring force, the cover body 2 is constrained to the container body 1 in a closed position by being pressed against the inner surface of the peripheral surface portion 21 of the cover body 2.

  In this way, the container with lid can properly store the contents a even after opening. Further, since the container body 1 can be repeatedly opened and closed by the lid body 2, the contents a can be dispensed. In addition, since the container with a lid is made of a paper sheet, it can be easily disposed of and recycled.

  Further, according to the present embodiment, the lid body 2 is formed with the inverted V-shaped cutout portions 25, 25 on both sides of the hinge 24, and the cutout end portions 25a, 25a are the outer peripheral surface of the container body 1 when the lid is opened. By abutting on and holding the state, the lid body does not naturally close by the elastic force of the hinge as in a conventional resin container, and the contents can be easily taken out.

  Moreover, according to this embodiment, since the opening of the container main body 1 closed by the lid body 2 is sealed by the inner seal portion 5, the initial sealing performance of the container can be further improved.

  Furthermore, according to this embodiment, the peripheral surface portion 21 of the lid body 2 is formed with a narrow width on the side opposite to the hinge 24, and a wide space is formed between the narrow width portion 26 c and the inverted V-shaped cutout portion 25. By doing so, since the lid opening operation is performed by putting a finger on the narrow portion 26c when the lid is opened, the position where the finger is put is specified, and the opening operability can be improved.

<Second Embodiment>
FIG. 8 is a longitudinal sectional view showing a second embodiment of a container with a lid according to the present invention.

  In the present embodiment, the inwardly curled portion 10 is formed at the upper opening end of the container main body 1. However, the present invention is not limited to this, and an outwardly curled portion may be formed.

<Third Embodiment>
FIG. 9 is a longitudinal sectional view showing a third embodiment of a lidded container according to the present invention.

  As shown in FIG. 9, in the container with a lid according to the present embodiment, the cross-sectional shape of the top surface portion 22 of the lid body 2 is formed in a substantially “U” shape that opens upward. The bent portion on the outer periphery of the top surface portion 22 is bonded so as to wrap from the outer side of the upper end of the peripheral surface portion 21, thereby forming the thread bottom portion 12 at the upper end of the lid body 2.

  As described above, according to the present embodiment, since the yarn bottom portion 12 is formed at the upper end of the lid 2, the strength of the lid 2 can be significantly increased.

<Fourth embodiment>
As shown in FIGS. 10 to 12, the lid body of the container with a lid according to this embodiment is different from the lid body 2 according to the first embodiment, and the inner surface of the top surface portion 22 has an opening edge of the container body 1. The cushion part 30 which consists of a cushioning material with moderate moisture-proof property which can contact | abut to 1a is attached.

  As the cushion material, foamed polypropylene, foamed polyethylene, sponge, elastomer, gel-like material, or the like can be used. Here, the cushion material is selected to have a moisture-proof effect.

  The cushion part 30 is formed in the same disk shape as the top surface part 22 in this embodiment. This cushion part 30 is stuck to the inner surface of the top surface part 22 with an adhesive or the like. The cushion portion 30 is not limited to the disc shape, and may be formed in other shapes such as a ring shape.

  The container provided with the lid 2 can be opened by the same operation as in the first embodiment. That is, when the purchaser or the like lifts the lid 2 placed on the container body 1 as shown in FIG. 10 above the opening of the container body 1, the lid 2 is folded along the broken line 24 a of the hinge 24 as shown in FIG. 11. It bends up and the opening of the container body 1 is opened. At the same time, a crease is attached to the fold line 24 a of the hinge 24.

  Therefore, when the purchaser or the like removes the inner seal portion 5 from the opening of the container main body 1, the purchaser or the like can take out the contents a from the container main body 1.

  Thereafter, when the purchaser or the like presses the lid 2 against the opening side of the container body 1 with a finger, the peripheral surface portion 21 and the top surface portion 22 of the lid body 2 are covered on the upper portion of the container body 1 as shown in FIG. Worn. At this time, the engagement pressure contact piece 28 has a restoring force due to bending on the fold line 29 a, so that it comes into pressure contact with the inner surface of the peripheral surface portion 21 of the lid 2. Thereby, the cover body 2 is restrained in the closed position with respect to the container main body 1, and the closed state is maintained until it is opened again by the purchaser or the like.

  In addition, when the lid 2 is put on the container body 1 again, the cushion portion 30 on the inner surface of the top surface portion 4 comes into contact with the opening edge 1a of the container body 1, so that intrusion of external moisture into the container body 1 is blocked. Is done.

  When a purchaser or the like tries to take out the contents a again from the container body 1, the lid body 2 may be lifted as shown in FIG. 11, and the lifted lid body 2 is folded by the folding line 24 a of the hinge 24. Keep open. For this reason, a purchaser etc. can take out the content a from the container main body 1 easily. At this time, since the engagement pressure contact piece 28 has a restoring force by bending, the engagement pressure contact piece 28 is inclined outward at a predetermined angle in the opened state of the lid body 2.

  After the contents a are taken out, the lid body 2 may be pressed against the opening side of the container body 1, and the peripheral surface portion 21 and the top surface portion 22 of the lid body 2 are connected to the container body 1 as shown in FIG. Deposited on top. At that time, since the engagement pressure contact piece 28 has a restoring force by bending on the fold line 29a, the lid body 2 is restrained to the container body 1 in a closed position by being pressed against the inner surface of the peripheral surface portion 21 of the lid body 2. The

  Further, when the lid 2 is put on the container body 1 again, the cushion part 30 on the inner surface of the top surface part 22 contacts the opening edge 1 a of the container body 1 as in the previous time. The cushion part 30 is brought into close contact with the opening edge 1a of the container body 1 by elastic deformation. In addition, the cushion part 30 is made of a moisture-proof material. Thereby, the penetration of external moisture into the container main body 1 is blocked by the cushion portion 30.

  In this case, since the engagement pressure contact piece 28 has a restoring force by bending on the fold line 29a, it comes into pressure contact with the inner surface of the peripheral surface portion 21 of the lid body 2 or after the engagement pressure contact piece 28 and the folding piece 27 are broken. Since they come in contact with each other on the separation line 28a, these function as locking means. The restraint of the lid 2 by the locking means and the elastic deformation of the cushion portion 30 combine to further improve the moisture resistance by the seal portion.

  In addition, when the sealing performance of the cover body 2 by the cushion part 30 is fully ensured from the beginning, the inner seal part 5 shown in FIG. 10 can be omitted.

  Thus, according to this embodiment, since the cushion part 30 contact | abuts to the opening edge 1a of the container main body 1, the penetration | invasion of the external moisture into the container main body 1 is interrupted | blocked, and the remaining contents a remain over a long period of time. It will be properly stored without being damaged. And since the cushion material of the cushion part 30 has moisture resistance, the penetration | invasion of the external moisture into the container main body 1 is interrupted | blocked more, and the content a can be preserve | saved more appropriately.

  In addition, according to the present embodiment, the cushion material is formed of any one of foamed polypropylene, foamed polyethylene, sponge, elastomer, and gel material, thereby preventing external moisture from entering the container body 1. Is possible. Other configurations and operations are the same as those in the first embodiment, and thus description thereof is omitted.

  In the present embodiment, the cushion portion 30 made of a cushioning material having an appropriate moisture-proof property capable of coming into contact with the opening edge 1a of the container body 1 on the inner surface of the top surface portion 22 is also the second embodiment shown in FIG. Applicable.

As shown in FIG. 13, the lid 2 of the present embodiment is different from the lid 2 according to the third embodiment in that the top surface portion 22 has a cushioning material layer having an appropriate moisture resistance as illustrated in FIG. 13. The moisture-proof layer 31 of the laminated sheet 4 a is in contact with the opening edge 1 a of the container body 1.

  The laminated sheet 22a shown in FIG. 13 has a layer structure of polyethylene layer / printing ink layer / paper layer / polyethylene layer / aluminum foil / polyethylene layer / foamed polyethylene layer from the outside.

  The laminated sheet is not limited to the one having the above layer structure, and a foamed polyethylene layer mainly composed of at least a moisture-proof paper layer (a laminate of paper and aluminum foil, etc.) via an adhesive layer (polyethylene layer). The thing of the layer structure which laminated | stacked can be employ | adopted. The cushion material layer 31 is not limited to foamed polyethylene, but can be formed of other materials such as foamed polypropylene, sponge, elastomer, gel material, and the like.

  The container body 1 provided with the lid 2 can be opened and resealed by the same operation as in the third embodiment.

  When the lid 2 is put on the container body 1 again, the cushion material layer 31 on the inner surface of the top surface portion 22 comes into contact with the opening edge 1 a of the container body 1. The cushion material layer 31 comes into close contact with the opening edge 1a of the container body 1 by elastic deformation. Thereby, the penetration | invasion into the container main body 1 of external moisture is interrupted | blocked.

  In this case, since the engagement pressure contact piece 28 has a restoring force by bending on the fold line 29a, it comes into pressure contact with the inner surface of the peripheral surface portion 21 of the lid body 2 or after the engagement pressure contact piece 28 and the folding piece 27 are broken. Since they come in contact with each other on the separation line 28a, these function as locking means. The constraint of the lid 2 by the locking means and the elastic deformation of the cushion material layer 31 combine to further improve the moisture resistance of the container.

  If the sealing performance of the lid 2 by the cushion material layer 31 is sufficiently ensured from the beginning, the inner seal portion 5 shown in FIG. 13 can be omitted.

  As described above, according to the present embodiment, the cushion material layer 31 of the top surface portion 22 contacts the opening edge 1a of the container body 1, so that intrusion of external moisture into the container body 1 is blocked, and the remaining contents a will be preserve | saved appropriately without being damaged over a long period of time. And since the cushion material layer 31 has moisture resistance, the penetration | invasion of the external moisture into the container main body 1 is interrupted | blocked more, and the content a can be preserve | saved more appropriately.

  In addition, according to the present embodiment, the laminated sheet 22a is formed by laminating paper on the cushion material layer 31 via the adhesive layer, thereby increasing the strength of the lid body and supplying moisture to the container body 1 with external moisture. It can be set as the container excellent in the environmental property which prevents invasion.

  Furthermore, according to the present embodiment, the cushion material layer 31 is formed of any one of foamed polyethylene, foamed polypropylene, elastomer, sponge, and gel-like material, thereby allowing external moisture to enter the container body 1. Can be prevented. Other configurations and operations are the same as those of the third embodiment, and thus description thereof is omitted.

<Sixth Embodiment>
As shown in FIGS. 14 and 15, the lid body 2 according to the sixth embodiment has substantially the same configuration as the lid body 2 of the first embodiment, and is connected to the container body 1 via a hinge 24. It is possible to open and close the opening of the container body 1 by rotating about the hinge 24 as a fulcrum. The lid body 2 is provided with a top surface portion 22 that covers the opening of the container main body 1, and a peripheral surface portion 21 that hangs down from the peripheral edge of the top surface portion 22 along the outer peripheral surface of the container main body 1. A hinge 24 is provided integrally.

  As shown in FIG. 17, the lid body 2 is different from the lid body 2 of the first embodiment, and the folding piece 27, the engagement pressure contact piece 28 and the engagement adhesive piece 29 shown in FIG. Is omitted from the peripheral surface portion 21.

  In this lid body 2, instead of the folding piece 27, the engagement pressure contact piece 28 and the engagement adhesive piece 29, the lid body 2 is provided at a location where the lid body 2 is in contact with the container body 1 as shown in FIGS. 14 to 16. A meshing tooth mechanism 33 for holding 2 in a closed state is provided.

  The meshing tooth mechanism 33 is constituted by a row of meshing teeth 34 and 35 provided on the inner peripheral surface of the lid body 2 and the outer peripheral surface of the container body 1 so as to be aligned in the opening / closing direction of the lid body 2. The meshing teeth 34 on the lid 2 side are inclined in the direction to open the lid 2, that is, the top surface 22 side of the lid 2, and the meshing teeth 35 on the container body 1 side are in the direction to close the lid 2, that is, the container body. 1 so as to be inclined toward the bottom side.

  In the sixth embodiment, the meshing teeth 34 and 35 are arranged in a plurality of rows on both the lid body 2 side and the container body 1 side, but both on the lid body 2 side and the container body 1 side. There may be only one. Further, one of the meshing teeth on the lid 2 side and the container body 1 side may be one and the other meshing tooth may be plural.

  The meshing teeth 34 on the lid 2 side are integrally formed with the lid side substrate 36 by injection molding a synthetic resin such as polyethylene, for example, as shown in FIGS. 16 and 20A to 20D.

  The lid side substrate 36 is curved along the peripheral surface portion 21 of the lid 2, and the meshing teeth 34 are formed on the curved concave surface of the lid side substrate 36.

  Each meshing tooth 34 extends long in the bending direction of the lid side substrate 36 and is arranged in a large number at a constant pitch in the height direction of the lid side substrate 36. Further, as shown in FIG. 20D, each meshing tooth 34 is formed to have a substantially triangular cross section, and this triangle is formed to be inclined toward the top plate portion 22 side of the lid 2. By this inclination, the tooth surface on the top plate portion 22 side of the lid body 2 in each tooth is formed as a steep slope or a vertical surface 34a with respect to the curved concave surface of the lid side substrate 36, and the tooth surface on the opposite side to the top plate portion 22 is the lid. It is formed as a gentle slope 34 b with respect to the curved concave surface of the body side substrate 36.

  In order to show the inclination direction of the meshing teeth 34, a projection 36a is formed on one side of the lid side substrate 36 as shown in FIGS. 20A and 20B. By using the projection 36a as an index, it is possible to attach the lid body side substrate 36 to the lid body 2 without changing the direction of the meshing teeth 34.

  Further, as shown in FIGS. 20A to 20D, on the curved convex surface of the lid side substrate 36, a ridge 37 is formed along the outline of the lid side substrate 36, and a groove 37a is formed so as to surround the ridge 37. It is formed. The ridge 37 has a sharp ridgeline, and the ridgeline is formed so as to protrude out of the curved convex surface. When the lid side substrate 36 is bonded to the inner surface of the peripheral surface portion 21 of the lid body 2 by an ultrasonic seal or the like, the ridges 37 are easily melted, so that the lid side substrate 36 is easily and quickly applied to the inner surface of the lid body 2. Glued.

  The curved convex surface of the lid-side substrate 36 may be a smooth surface without forming the ridges 37 and the like. Moreover, you may adhere | attach on the cover body 2 using an adhesive agent, a double-sided adhesive tape, etc., without using ultrasonic bonding.

  The engagement teeth 35 on the container body 1 side are integrally formed with the container body side substrate 38 as shown in FIGS. 16 and 21A to 21D by the same manufacturing method as the engagement teeth 34 on the lid body side.

  The container body side substrate 38 is curved along the peripheral wall of the container body 1, and the meshing teeth 35 are formed on the curved convex surface of the container body side substrate 38.

  Further, on the curved concave surface of the container body side substrate 38, the ridges 37 and grooves 37 a surrounding the ridges 37 are formed in the same manner as the lid side substrate 36.

  Each meshing tooth 35 extends long in the bending direction of the container main body side substrate 38 and is arranged in a large number at a constant pitch in the height direction of the container main body side substrate 38. The meshing teeth 35 on the container body 1 side are formed to extend longer in the bending direction of the container body side substrate 28 than the meshing teeth 24 on the lid 2 side. By forming in this way, even if the lid body 2 is twisted or inclined when the lid body 2 is closed, the meshing teeth 34 and 35 are more accurately engaged with each other.

  Further, the number of meshing teeth 35 on the container body 1 side is smaller than the number of meshing teeth 34 on the lid 2 side. The meshing teeth 35 on the container body 1 side are exposed to the outside of the container body 1 when the lid 2 is opened. By reducing the number of meshing teeth 35 in this way, the presence of the meshing teeth 35 is made inconspicuous. be able to. Of course, if necessary, the number of mesh teeth 35 on the container body side may be larger than or equal to the number of mesh teeth 34 on the opening / closing lid side.

  Further, as shown in FIG. 21D, each meshing tooth 35 is formed to have a substantially triangular cross section, and the triangular shape is inclined to the bottom side of the container body 1. By this inclination, the tooth surface on the bottom side of the container body 1 in each meshing tooth 35 is formed as a steep slope or a vertical surface 35a with respect to the curved convex surface of the container body side substrate 38, and the teeth on the opposite side to the bottom of the container body 1 are formed. The surface is formed as a gentle slope 35b.

  In order to indicate the inclination direction of each meshing tooth 35, a protrusion 38 a is formed on one side of the container main body side substrate 38. By using the protruding direction of the protrusion 38a as an index, the container body-side substrate 38 can be attached to the container body 1 without changing the direction of the meshing teeth 35.

  The protrusion 38a of the container body side substrate 38 has a curved edge, whereas the protrusion 36a of the lid body side substrate 36 has a polygonal edge. By using the shape of the projections 38a and 36a as an index, it is possible to prevent an error in attaching the substrates 38 and 36 between the container body 1 and the lid 2. The shapes of the protrusions 38a and 36a can be changed to other desired shapes as necessary.

  Next, the operation of the lidded container having the above configuration will be described.

  The lid 2 is in a state as shown in FIGS. 15 and 16 when not opened.

  A purchaser or the like of a container with a lid on which the lid body 2 is attached presses the lower part of the meshing tooth mechanism 33 on the peripheral wall of the container body 1 with his / her finger slightly when taking out the contents a. Then, the peripheral wall of the container body 1 is slightly bent, and the meshing teeth 34 and 35 in the meshing tooth mechanism 33 are disengaged. That is, the contact between the steep slopes or the vertical surfaces 34a and 35a is eliminated between the meshing teeth 34 and 35 engaged with each other.

  Therefore, when the purchaser or the like lifts the lid body 2 above the opening of the container main body 1, the hinge 24 is bent on the fold line 24a as shown in FIG. 18, and the opening of the container main body 1 is opened. At the same time, a crease is attached to the fold line 24 a of the hinge 24.

  Even if the purchaser or the like removes his / her finger from the lid body 2 and releases the lid body 2, the lid body 2 is held open by the folding of the broken line 24 a.

  The purchaser or the like can remove the content a from the container body 1 by removing the inner seal portion 5 from the opening of the container body 1.

  Thereafter, when the purchaser or the like presses the lid 2 against the opening side of the container body 1 with a finger, the peripheral surface portion 21 and the top surface portion 22 of the lid body 2 cover the upper portion of the container body 1 as shown in FIG. . When the lid 2 is being covered, the gentle slopes 34b, 35b between the meshing teeth 34, 35 in the meshing tooth mechanism 33 come into contact with each other, so that the lid 2 is closed smoothly.

  When the lid 2 is completely closed, the meshing teeth 34, 35 of the meshing tooth mechanism 33 are meshed again as shown in FIG. That is, the steep slopes or the vertical surfaces 34a, 35a contact each other between the meshing teeth 34, 35. Thereby, the cover body 2 is restrained in the closed position with respect to the container main body 1, and the closed state is maintained until it is opened again by the purchaser or the like. In the closed state, the steep slope or the vertical surfaces 34a, 35a between the meshing teeth 34, 35 function as a return, so that the closed state of the lid 2 is firmly maintained.

  When a purchaser or the like tries to take out the contents a from the container body 1 again, he or she presses the lower part of the meshing tooth mechanism 33 in the container body 1 with his / her finger slightly and lifts the lid 2 as shown in FIG.
