Summary of the Invention

Problems to be Solved by the Invention

[0004] In Patent Document 1, since a magnet is used as the locking mechanism of the lid, it is necessary to attach magnets to the mouth cylinder portion and the lid respectively during assembly, and when disposing of it, it is necessary to separate the magnet from the container, and there is room for improvement in terms of assembly and cost.

[0005] Therefore, an object of the present invention is to provide a jar-type container having a locking mechanism that can reliably lock the lid by simply pushing the lid from above against the cylindrical portion of the container body that serves as the outlet for taking out the contents without using a magnet.

Means for Solving the Problems

[0006] The first jar-type container of the present invention, developed to achieve the above objective, comprises 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 that is 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 the cylindrical portion has an inclined surface formed on its upper outer wall including the open end and having a downward slope toward the radially outward direction, and the inclined surface The inner lid has open ends connected at at least two locations on its lower edge, and grooves that are connected to the open ends and have 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 at least two locations on its inner circumferential wall that can slide along the grooves by a pushing motion of the lid or an upward motion of the lid accompanied by rotation, and the grooves have recesses provided in the curved portion that engage the projections when the lid is pushed in to lock the lid against the cylindrical portion, but release the lock of the lid against the cylindrical portion by disengaging the projections when the lid is pulled up accompanied by rotation.

[0007] Furthermore, in the first jar-type container of the present invention, (1) 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. (2) The elastic piece is partitioned by two slits that sandwich the projection in the circumferential direction of the inner lid and extend in the vertical direction of the inner lid. It is preferable.

[0008] 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 portion 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 portion and seals and holds the container body while the refill container is stored in the storage space, wherein the refill container comprises a main body portion having an open upper end and having a filling space for contents partitioned below the open upper end, and an annular body connected to the open upper end and having an inclined surface that slopes downwards radially outward, into which the open end of the cylindrical portion can be detachably fitted, and the lid is located along the outer surface of the container body The invention comprises an outer lid having sides, and an inner lid fitted and held inside the outer lid, having an inner circumferential wall facing the outer circumferential wall of the cylindrical portion, wherein the cylindrical portion has open ends formed at least two locations on the outer circumferential wall directly below the open end, and grooves connected to the open ends, forming a U-shape or V-shape with a curved portion formed at the lower end of the cylindrical portion, and the inner lid has projections at least two locations on its inner circumferential wall that can slide along the grooves by a pushing operation of the lid or an upward operation accompanied by rotation of the lid, wherein the grooves have recesses provided in the curved portions that engage the projections by a pushing operation of the lid to lock the lid to the cylindrical portion, but release the lock of the lid to the cylindrical portion by disengaging the projections by an upward operation accompanied by rotation of the lid.

[0009] Furthermore, in the second jar-type container of the present invention, (1) The annular body comprises a hanging piece that is suspended along the outer peripheral wall of the cylindrical portion, and the hanging piece has a lower edge that is located at the upper edge of the groove when the annular body is fitted into the open end of the cylindrical portion, thereby positioning the annular body relative to the cylindrical portion. (2) 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. (3) The elastic piece is partitioned by two slits that sandwich the projection in the circumferential direction of the inner lid and extend in the vertical direction of the inner lid. It is preferable. [Effects of the Invention]

[0010] According to the jar-type container of the present invention, when the lid is pressed down from above onto the open end of the cylindrical portion connected to the container body, a projection provided on the inner lid of the lid rides up onto an inclined surface provided on the open end of the cylindrical portion or the upper open end of the refill container, and is smoothly guided into a U-shaped or V-shaped groove provided on the outer circumferential wall of the cylindrical portion. The lid slides along the groove and fits into a recess provided in a curved portion located at the lower end of the groove, thereby easily locking the lid to the cylindrical portion. As a result, the lid can be easily closed by placing it over the cylindrical portion connected to the container body or the refill container from above and pressing it down 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 the opened jar-type container is attached to the user's fingertips, the lid can be closed smoothly without slipping.

[0011] Furthermore, according to the present invention, the inner lid has an elastic piece that is cantilevered or supported at both ends by having a slit in its inner circumferential wall, and the projection is provided by the elastic piece so as to be displaceable in the radial direction. Therefore, when the lid is pushed into or pulled up against the cylindrical portion, the projection is displaced in the radial direction, which facilitates the fitting of the projection into the recess and the release of the fitted state.

[0012] Furthermore, according to the present invention, the jar-type container can be reused repeatedly by replacing the refill container. [Brief explanation of the drawing]

[0015] Reference numeral 1 in the figure is a container body having an external shape presenting a rectangular shape and having an accommodation space M for contents such as moisturizing cream partitioned and formed inside thereof, 2 is a cylindrical portion connected to the upper surface portion of the container body 1, and 3 is a lid body detachably attached to the cylindrical portion 2 and hermetically holding the accommodation space M, and these are mainly constituted by using a synthetic resin material. Hereinafter, the direction along the axis O of the container body 1 is referred to as the vertical direction, the direction intersecting the axis O as viewed from the vertical direction is referred to as the radial direction, and the direction orbiting around the axis O as viewed from the vertical direction is referred to as the circumferential direction.

[0016] The container body 1 has a horizontal shoulder portion 12 from the upper end edge of the bottomed cylindrical body portion 11, and the cylindrical portion 2 is erected and integrally formed at the central portion of the shoulder portion 12. The cylindrical portion 2 has an open end 21 opened upward, and the contents filled in the accommodation space M can be taken out through the open end 21.

[0017] Furthermore, the cylindrical portion 2 has an inclined surface 26 provided on its outer circumferential wall, including the open end 21, which slopes downward radially outward, and a plurality of V-shaped grooves 22 on its outer circumferential 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 circumferential 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 circumferential 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 circumferential wall of the inner lid 32, which will be described later.

[0018] The lid 3 consists of a rectangular outer lid 31 having an outer surface that conforms to 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 mechanism such as an undercut. The outer lid 31 has a rectangular cylindrical peripheral wall 31a and a top wall 31b connected to the upper edge of the peripheral wall 31a. A packing 33 made of silicone rubber or the like is provided on the lower surface of the top wall 31b, and when the lid is closed, the packing 33 presses against the open end 21 of the cylindrical portion 2, thereby sealing and maintaining the filling space M of the container body 1.

[0019] 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 inner lid 32 at 90-degree intervals at positions corresponding to the corners of the outer lid 31.

[0020] 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.

[0021] 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.

[0022] 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.

[0023] 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 Figure 6, when the lid 3 is placed over the cylindrical portion 2 and pushed downward, 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.

[0024] 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.

[0025] To remove the lid 3 from the cylindrical part 2, the lid 3 can be rotated either clockwise or counterclockwise. As shown in Figure 6, for example, rotating the lid 3 clockwise will cause the projection 4 to disengage from part A, and rotating the lid 3 counterclockwise will cause it to disengage from part B.

[0026] 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.

[0027] As shown in Figure 7, the elastic piece 6 may be partitioned by two slits 5 provided along the vertical direction of the peripheral wall 32a at the left and right positions of the projection 4. When the elastic piece 6 is formed along the vertical direction of the peripheral wall 32a in this way, the elastic piece 6 becomes more flexible in the radial direction, so when the lid 3 is placed over the cylindrical portion 2 of the container body 1 and the lid 3 is pressed down with the back of the hand, the projection 4 easily rides onto the inclined surface 26 provided at the opening end 21, and the lid 3 can be smoothly attached to the cylindrical portion 2. Furthermore, when the lid 3 is rotated to remove it from the cylindrical portion 2, the projection 4 (elastic piece 6) fitted into the recess 25 twists, suppressing the rotation, thus improving the locking function and preventing the lid 3 from being accidentally opened during handling. In this embodiment, the elastic piece 6 is cantilevered along the peripheral wall 32a, but the elastic piece 6 may also be supported at both ends by the peripheral wall 32a.

[0028] Figures 8(a), (b) to 11 schematically show another embodiment of a jar-type container 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.

[0029] In Figures 8-11, reference numeral 7 denotes a refill container. The refill container 7 can be composed of a main body portion 72 having an upper open end 71, with a content filling space M1 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, which is 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 is made of a synthetic resin material.

[0030] 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.

[0031] 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 part (open end 23) of the groove 22, making it easy to lock the lid 3 in place.

[0032] 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, moves upward along the groove 22, rides onto the inclined wall 77 and slides, allowing the lid 3 to be easily removed.

[0033] 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]

[0034] A jar-type container according to the present invention can be suitably used as a container for storing the contents of cream-type cosmetics, pharmaceuticals, and the like. [Explanation of symbols]
