Summary of the Invention

Problems to be Solved by the Invention

[0004] Many of such jar-type containers are configured such that a sheet-like packing made of silicone rubber or the like is provided on the lower surface of the top wall of the lid, and when the lid is closed, the packing is pressed against the opening end of the mouth cylinder portion, so that the filling space of the container body can be hermetically held.

[0005] However, such a sheet-like packing may have a gap between the lid and the opening end of the mouth cylinder portion due to the tightening condition when the lid is closed, and the filling space cannot be sealed, and there is a risk that the contents may leak during handling or the contents may oxidize and become soiled, and there is room for improvement.

[0006] Therefore, an object of the present invention is to provide a jar-type container that can be easily closed by pushing the lid from above against the cylindrical portion of the container body that serves as the outlet for the contents, and at that time, the filling space of the container body can be reliably hermetically held by the lid. [Means for solving the problem]

[0007] The first jar-type container of the present invention, developed to achieve the above objective, is a jar-type container comprising: a container body that partitions and forms a space for filling contents; a cylindrical portion connected to the container body and having an open end that opens upwards for removing contents filled in the filling space; and a lid that is detachably attached to the cylindrical portion and seals and holds the filling space, wherein the lid comprises an outer lid having an outer surface along the outer surface of the container body, and an inner lid that is fitted and held inside the outer lid and has an inner wall facing the outer wall of the cylindrical portion, and is held in a locked state by a pushing motion by linking with the lower end of the outer wall of the cylindrical portion, and the locked state is released by an upward motion, and the outer lid is provided with a packing on the lower surface of the outer lid that seals the open end by making close contact with an annular inclined wall provided on the inside of the open end when holding the lid in a locked state.

[0008] Furthermore, in the first jar-type container of the present invention, (1) The packing comprises a packing body having a sealing surface that can adhere closely to the annular inclined wall and a mortar shape that bulges toward the filling space, and one or more cantilever support pieces, one end of which is connected to the edge of the packing body and the other end which is sandwiched between the outer lid and the inner lid, wherein the cantilever support piece has a biasing force that presses the packing body against the opening end and firmly adheres the sealing surface to the annular inclined wall due to elastic deformation when the lid is held in a locked state. (2) The cylindrical portion has an inclined surface formed on the outer peripheral wall of its upper region including the open end, which is given a downward slope toward the radially outward direction, open ends connected at least two locations on the lower edge of the inclined surface, and a groove portion that is connected to the open ends and has a curved portion formed at the lower end of the cylindrical portion, forming a U-shape or V-shape, and the inner lid has projections at least two locations on its inner peripheral wall that are slidable along the groove portion by a pushing operation of the lid and an upward operation of the lid accompanied by rotation, and the groove portion has recesses provided in the curved portion that engage the projections when the lid is pushed in, locking the lid to the cylindrical portion, but release the projections when the lid is pulled up accompanied by rotation, thereby releasing the lock of the lid to the cylindrical portion. (3) The inner lid is cantilevered or supported at both ends along the inner circumferential wall and has an elastic piece that displaces the projection in the radial direction of the inner lid. It is preferable.

[0009] Furthermore, the second jar-type container of the present invention comprises a container body that partitions and forms a storage space for storing a refill container filled with contents, a cylindrical part connected to the container body and having an open end that opens upwards for attaching and detaching the refill container, and a lid that is detachably attached to the cylindrical part and seals and holds the container body while the refill container is stored in the storage space, wherein the refill container has an upper open end with an annular inclined wall on the inside, a main body portion having a filling space for contents partitioned below the upper open end, and a part connected to the upper open end and the outer periphery wall of the main body portion The container comprises an annular body into which the open end of the cylindrical portion can be detachably fitted in a downward-facing open recess formed between them, and the lid comprises an outer lid having an outer surface along the outer surface of the container body, and an inner lid fitted and held inside the outer lid and having an inner circumferential wall facing the outer circumferential wall of the cylindrical portion, and is held in a locked state by a pushing motion by linking with the lower end of the outer circumferential wall of the cylindrical portion, and the locked state is released by an upward motion, and is characterized in that a packing is provided on the lower surface of the outer lid that, when holding the lid in a locked state, makes close contact with an annular inclined wall provided on the inside of the upper open end and seals the upper open end.

[0010] Furthermore, in the second jar-type container of the present invention, (1) The packing comprises a packing body having a sealing surface that can adhere closely to the annular inclined wall and a mortar shape that bulges toward the upper open end, and one or more cantilever support pieces, one end of which is connected to the edge of the packing body and the other end which is sandwiched between the outer lid and the inner lid, wherein the cantilever support piece has a biasing force that presses the packing body against the upper open end and firmly adheres the sealing surface to the annular inclined wall due to elastic deformation when the lid is held in a locked state. (2) The cylindrical portion has open ends formed at least two locations on the outer peripheral wall directly below the open end, and a groove portion that is connected to the open end and has a curved portion formed at the lower end of the cylindrical portion, forming a U-shape or V-shape, and the inner lid has projections at least two locations on its inner peripheral wall that can slide along the groove portion by pushing the lid in and pulling up with rotation of the lid, and the groove portion has a recess provided in the curved portion that locks the lid to the cylindrical portion by fitting the projection when the lid is pushed in, but releases the lock of the lid to the cylindrical portion by disengaging the projection when the lid is pulled up with rotation, (3) The inner lid is cantilevered or supported at both ends along the inner circumferential wall and has an elastic piece that displaces the projection in the radial direction of the inner lid. (4) The annular body comprises a hanging piece that is suspended along the outer peripheral wall of the cylindrical portion and an inclined surface that is given a downward slope toward the radially outward direction, wherein the hanging piece has a lower edge end that is located on the upper edge of the groove and positions the annular body relative to the cylindrical portion when the annular body is fitted into the open end of the cylindrical portion. It is preferable. [Effects of the Invention]

[0011] According to the jar-type container of the present invention, when the lid is pushed down toward the cylindrical portion connected to the container body to lock (close the lid), a packing provided on the lower surface of the lid (outer lid) adheres tightly to the annular inclined wall formed on the inside of the open end of the cylindrical portion or the inside of the upper open end of the refill container, thereby sealing the filling space of the container body. Therefore, it is possible to prevent the contents of the container body from leaking out or from being oxidized and contaminated after use begins.

[0012] In particular, in the present invention, since the packing body has a mortar-like shape that bulges out toward the filling space of the container body, when the lid is pressed down, the lower surface (sealing surface) of the packing body easily adheres to the annular inclined wall formed in the cylindrical part or refill container, and the filling space of the container body can be reliably sealed. Furthermore, the packing has one or more cantilever support pieces connected to the edge of the packing body, and when the lid is locked, the cantilever support pieces elastically deform, pressing the packing body (sealing surface) firmly against the annular inclined wall, allowing for a strong and secure seal.

[0013] Furthermore, according to the present invention, simply by pressing the lid down from above onto the open end of the cylindrical part connected to the container body or the open upper end of the refill container, the lid can be locked in place by engaging with the lower end of the outer peripheral wall of the cylindrical part. Therefore, the lid can be easily closed by pressing it with the back of the hand without having to rotate it by hand. For example, even if moisturizing cream or the like taken out of an open jar container is attached to the user's fingertips, the lid can be closed smoothly without slipping.

[0014] Furthermore, according to the present invention, the jar-type container can be reused repeatedly by replacing the refill container. [Brief explanation of the drawing]

[0017] Reference numeral 1 denotes a container body having a rectangular external shape and a filling space M for contents such as moisturizing cream is partitioned inside; reference numeral 2 denotes a cylindrical portion connected to the upper surface of the container body 1; and reference numeral 3 denotes a lid that is detachably attached to the cylindrical portion 2 and seals and holds the filling space M. These are mainly made of synthetic resin material. In this embodiment, the container body 1 and lid 3 are rectangular in shape, but are not limited to this and can be made of various shapes such as circular or elliptical.

[0018] The container body 1 has a bottomed cylindrical body 11 with a horizontal shoulder portion 12 extending from the upper edge of the shoulder portion 12, and a cylindrical portion 2 is erected in the central part of the shoulder portion 12 and formed integrally. The cylindrical portion 2 has an open end 21 that is open towards the top, and the contents filled in the filling space M can be removed through this open end 21.

[0019] Furthermore, the cylindrical portion 2 has an annular inclined wall 27 provided on the inside of the open end 21, an inclined surface 26 provided on the outer peripheral wall including the open end 21 and having a downward slope toward the radially outward direction, and a plurality of V-shaped grooves 22 on the outer peripheral wall. The grooves 22 have an open end 23 connected to the lower edge of the inclined surface 26, and a curved portion 24 is formed at the lower end to form a V shape. In this embodiment, four grooves 22 are provided on the outer peripheral wall of the cylindrical portion 2 at 90-degree intervals at positions corresponding to the corners of the container body 1, but it is preferable to provide at least two grooves 22 on the outer peripheral wall of the cylindrical portion 2. The grooves 22 may also be provided in a U shape. In addition, the curved portion 24 of the groove 22 is provided with a recess 25 that can be fitted with a projection 4 provided on the inner peripheral wall of the inner lid 32, which will be described later.

[0020] The lid 3 consists of a rectangular outer lid 31 having an outer surface that follows the outer surface of the container body 1, and an inner lid 32 that is fitted and held inside the outer lid 31 by a fitting means such as an undercut. The lid 3 can have any structure as long as it is held in a locked state by being pushed into the open end 21 of the cylindrical portion 2 and linked to the lower end of the outer peripheral wall of the cylindrical portion 2, and the locked state is released by being pulled up, and is not limited to the illustrated structure. For example, a magnet may be provided on either the lid 3 or the cylindrical portion 2, and an adsorption member that can be attracted to the magnet may be provided on the other, and the lid 3 and the cylindrical portion 2 (container body 1) may be set in a closed state (locked state) by the magnetic attraction acting between them.

[0021] The outer cover 31 has a rectangular cylindrical peripheral wall 31a and a top wall 31b connected to the upper edge of the peripheral wall 31a. The inner lid 32 has a cylindrical circumferential wall 32a having an inner circumferential wall facing the outer circumferential wall of the cylindrical portion 2, and flange portions 32b and 32c that connect to the outer circumferential wall of the circumferential wall 32a at the lower and lower end positions, respectively, and project outward. In addition, four protrusions 4 are provided on the inner circumferential wall of the circumferential wall 32a at 90-degree intervals corresponding to the corners of the outer lid 31.

[0022] The peripheral wall 32a of the inner lid 32 is provided with two slits 5 along the circumferential direction of the peripheral wall 32a at the upper and lower positions of the projection 4, and the portion of the peripheral wall 32a partitioned by the slits 5 becomes an elastic piece 6 that can be displaced radially. In this embodiment, a vertical notch 51 connected to the slits 5 is provided in the center of the projection 4. The notch 51 divides the elastic piece 6 into left and right halves, and it is cantilevered to the peripheral wall 32a, making radial displacement easier. In this embodiment, the slits 5 are provided on both the left and right sides along the circumferential direction of the peripheral wall 32a from the notch 51, but the slits 5 may be provided on only one side from the notch 51.

[0023] In this example, four projections 4 are provided at 90-degree intervals on the inner circumferential wall 32a of the inner lid 32, corresponding to the corners of the outer lid 31, and four grooves 22 are provided at 90-degree intervals on the outer circumferential wall of the cylindrical portion 2, corresponding to the corners of the container body 1. However, the number and positions of these are not particularly limited. From the viewpoint of balance, it is preferable to provide at least two projections 4 and grooves 22 at opposing positions.

[0024] The inner cover 32 is inserted into the lower end opening of the outer cover 31 and pressed down, causing the flange portion 32b to undercut fit into the annular rib 31c provided on the inner circumferential surface of the peripheral wall 31a of the outer cover 31, and the flange portion 32c to engage with the recess 31d provided on the lower end edge of the outer cover 31, thereby assembling them together.

[0025] A packing 33 made of synthetic resin or silicone rubber that is resistant to deformation is provided on the lower surface of the top wall 31b of the outer cover 31. The packing 33 has a packing body 34 that is shaped like a mortar and pestle and bulges out toward the filling space M, and one or more cantilever support pieces 35, one end of which is connected to the edge of the packing body 34 and the other end which is sandwiched between the outer cover 31 and the inner cover 32.

[0026] The packing 33 is inserted between the inner lid 32 and the outer lid 31 when the inner lid 32 is fitted into the outer lid 31 using an undercut fitting, and the cantilever support piece 35 is attached to the lid 3 by being sandwiched between the top wall 31b of the outer lid 31 and the top of the peripheral wall 32a of the inner lid 32.

[0027] As shown in Figure 8, when the lid 3 is placed over the cylindrical portion 2 and the lid 3 is pressed down, the sealing surface 34a of the mortar-shaped packing body 34 of the packing 33 comes into contact with the annular inclined wall 27 formed on the inside of the open end 21 of the cylindrical portion 2, as shown in Figure 9(a). When the lid 3 is pressed down further, the sealing surface 34a comes into close contact with the annular inclined wall 27, as shown in Figure 9(b), sealing the open end 21 and keeping the filling space M of the container body 1 sealed.

[0028] Furthermore, as shown in Figure 9(b), it is preferable that the cantilever support piece 35 has a biasing force that presses the packing body 34 against the annular inclined wall 27 when the lid 3 is held in a locked state, causing the sealing surface 34a to adhere firmly to the annular inclined wall 27. The cantilever support piece 35 has a locking projection 35a on the lower surface of its end, and the engaging projection 35a engages with the top of the peripheral wall 32a of the inner lid 32, thereby preventing the packing 33 (cantilever support piece 35) from falling out between the outer lid 31 and the inner lid 32.

[0029] Furthermore, by providing the annular inclined wall 27 inside the open end 21 of the cylindrical portion 2, positioning ribs or the like are formed on the top surface of the open end 21, allowing the container to be used even in containers where sealing on the top surface is insufficient.

[0030] To attach the lid 3 to the cylindrical portion 2 of the container body 1 and seal the filling space M of the container body 1, as shown in Figures 8 and 9, the lid 3 should be placed over the cylindrical portion 2 and pushed downwards. When this is done, the projection 4 provided on the inner lid 32 rides up onto the inclined surface 26 provided on the outer peripheral wall including the open end 21 of the cylindrical portion 2, slides along the inclined surface 26 while being displaced radially, and is smoothly guided to the open end 23 of the groove 22. Then it slides downward along the groove 22 and fits into the recess 25 formed in the curved portion 24 at the lower end of the groove 22. As a result, the lid 3 is locked to the cylindrical portion 2, and the filling space M of the container body 1 is sealed and held by the lid 3.

[0031] To remove the lid 3, the projection 4 (elastic piece 6) is displaced radially by an upward motion accompanied by rotation of the lid 3, thereby detaching it from the recess 25, releasing the lock of the lid 3 on the cylindrical portion 2, and then the projection 4 is slid along the groove 22 and pulled out from the open end 23. This opens the filling space M of the container body 1, allowing the contents to be removed. At this time, as described above, the projection 4 is divided into two halves by the notch 51 and cantilevered by the elastic piece 6, making it easy to displace the projection 4 radially and detach it from the recess 25.

[0032] To remove the lid 3 from the cylindrical part 2, the lid 3 can be rotated either clockwise or counterclockwise.

[0033] Furthermore, it is desirable that the elastic piece 6 has a biasing force that pushes the projection 4 toward the bottom of the recess 25 when the projection 4 is fitted into the recess 25, while also inducing a displacement that allows the projection 4 to be released from the recess 25 relatively easily.

[0034] Figures 10 to 15 schematically show a second jar-type container embodiment according to the present invention, in which the filling space M of the container body 1 is used as a storage space for a refill container filled with contents, and the refill container is placed in that storage space. The same parts as in the embodiment of the first jar-type container will not be explained.

[0035] Reference numeral 7 denotes a refill container. The refill container 7 can be configured to include: a main body portion 72 having an upper open end 71 with an annular inclined wall 78 on the inside, and a filling space M1 for contents formed below the upper open end 71; an annular body 74 connected to the upper open end 71 and having a downward open recess 73 formed between it and the outer peripheral wall of the main body portion 72, into which the open end 21 of the cylindrical portion 2 is detachably fitted; and a hanging piece 75 connected to the annular body 74 and held hanging down along the outer peripheral wall of the cylindrical portion 2 when it is fitted to the open end 21 of the cylindrical portion 2. The refill container 7 is made of a synthetic resin material.

[0036] The refill container 7 is fitted and held in place by inserting the main body portion 72 from above the open end 21 of the cylindrical portion 2, fitting the open end 21 into the downward-facing open recess 73 of the annular body 74, and pressing it from above. At this time, the lower edge end 75a of the hanging piece 75 is positioned along the upper edge 22a of the groove portion 22 formed in the outer peripheral wall of the cylindrical portion 2.

[0037] The refill container 7, having the above configuration, has an inclined surface 76 formed on the outer surface of the annular body 74, which is sloped downward radially outward. As a result, when the lid 3 is attached to the cylindrical part 2, when the lid 3 is pushed down, the projection 4 provided on the inner circumferential wall of the inner lid 32 slides along the inclined surface 76 and is smoothly guided to the open portion of the groove 22 (the open end 23 formed on the outer circumferential wall directly below the open end 21), allowing the lid 3 to be easily locked.

[0038] In this embodiment, the packing 33 can be the same as the packing 33 shown in Figures 1 to 9 above. When the lid 3 is held in the locked state, as shown in Figure 15(b), the packing body 34 is pressed against the upper open end 71 by the biasing force due to the elastic deformation of the cantilever support piece 35, and the sealing surface 34a firmly adheres to the annular inclined wall 78.

[0039] Furthermore, by providing the annular inclined wall 78 on the inside of the upper open end 71 of the refill container 7, even if adhesive residue remains on the top surface of the refill container 7 from, for example, when an aluminum sheet is attached, or if positioning ribs are formed, the adhesion between the packing 33 and the sealing surface 34a will not be hindered, and high adhesion can be achieved.

[0040] Furthermore, it is preferable that the annular body 74 be provided with an inclined wall 77 that connects to the inclined surface 76 and has a slope opposite to that of the inclined surface 76, at a position corresponding to the open end 23 of the groove 22. When removing the lid 3, if the lid 3 is pulled up while being rotated, the projection 4 provided on the inner circumferential wall of the inner lid 32 disengages from the recess 25, slides upward along the groove 22, rides up onto the inclined wall 77 and slides, allowing the lid 3 to be easily removed.

[0041] Furthermore, used refill containers 7 can be easily removed by grasping the annular body 74 with your fingers and pulling it upward, which disengages the engagement between the open end 21 of the cylindrical part 2 and the downward-facing open recess 73. By replacing it with a new refill container 7, the jar-type container can be reused repeatedly, thus reducing waste. [Industrial applicability]
