Description

[Technical field]

[0001] The present invention relates to a refill container for refilling a jar. [Background technology]

[0002] Conventionally, wide-mouthed containers called jars are used to store contents such as beauty creams. After the contents in the jar are used up, the empty jar is replenished by transferring the contents from another refill container, and this refill container is called a refill container.

[0003] There are two types of refill containers: those in which the entire refill container is placed inside a jar container to replenish the contents (see Reference 1), and those in which only the contents inside the refill container are transferred to the jar container.

[0004] [Patent Document 1] JP 2011-157083 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, when transferring only the contents from the refill container to the jar container, there is a concern that the contents contained in the refill container may remain in the refill container. Also, it would be preferable if the contents could be easily transferred from the refill container to the jar container.

[0006] The present invention has an objective of solving such problems and providing a refill container that can be easily transferred without leaving any contents remaining in the refill container. [Means for solving the problem]

[0007] The present invention is a refill container that can transfer contents into a jar container, comprising a refill container body having an opening for accommodating the contents, and an inner plate that is disposed within the refill container body and slides from the bottom side of the refill container toward the opening side, and the contents can be pushed out into the jar container by sliding the inner plate with the opening of the refill container facing the opening of the jar container.

[0008] With regard to the above-mentioned refill container, it is preferable that the refill container body has an upright wall that stands up from the periphery of the opening of the refill container body and can be attached to the opening of the jar container, the upright wall has an open portion that cuts out the upright wall to the opening of the refill container body, and after sliding the inner plate to push the contents into the jar container, the refill container attached to the jar container can be slid in a direction such that the open portion is toward the rear in the direction of travel to wipe out any contents remaining in the opening of the refill container.

[0009] Furthermore, with respect to the above-mentioned refill container, it is preferable that a protrusion is formed on the inner surface at the end of the upright wall on the side of the open portion, which protrudes radially inward from the refill container body and can be engaged with the opening of the jar container.

[0010] Furthermore, with respect to the above-mentioned refill container, it is preferable that an annular seal having an opening with an inner diameter smaller than the opening of the refill container, and a sealing seal that covers the opening of the annular seal and is peelably attached to the annular seal, are affixed to the opening of the refill container. Effect of the Invention

[0011] According to the refill container of the present invention, the contents of the refill container can be transferred by a simple operation without leaving any of the contents remaining in the refill container. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] Hereinafter, an embodiment of a refill container according to the present invention will be described with reference to the accompanying drawings. Fig. 1 is a front cross-sectional view showing a refill container 1 according to an embodiment of the present invention. Fig. 2 is a plan view showing a refill container 1 according to an embodiment of the present invention.

[0014] As shown in Figures 1 and 2, the refill container 1 of the embodiment of the present invention is a refill container 1 that can transfer contents C to a jar container 4 (see Figure 3), and is equipped with a refill container body 2 that has an opening O3 and contains the contents C, an inner plate 22 that is arranged in the refill container body 2 and slides from the bottom 211 side of the refill container 1 toward the opening O3, and a sealing member 3 that is affixed to the opening O3 of the refill container 1.

[0015] The refill container body 2 is an approximately cylindrical member and includes a bottom 211, a cylindrical peripheral wall portion 21 extending upward from the peripheral portion of the bottom 211, a flange portion 213 formed in a ring shape radially outward at the upper end portion of the peripheral wall portion 21, and a cylindrical upright wall 214 extending upward from the peripheral portion of the flange portion 213.

[0016] The bottom 211 is annular, and has an opening O1 in the center, which is large enough for a user's finger to be inserted into. In addition, on the upper surface of the bottom 211, an inner cylinder 211a is provided radially outward from the opening O1, extending upward, at a predetermined distance from the peripheral wall 21.

[0017] The flange portion 213 is annular and extends in three directions, the upper side, the left side, and the right side of the plane of the paper in the plan view of Fig. 2. The left and right sides of the flange portion 213 in Fig. 2 form a wide portion 213w that is wider than the upper side of the plane of the paper. The wide portion 213w has a through hole 213a formed therethrough so as to have a rectangular shape in a plan view.

[0018] The standing wall 214 stands from the periphery of the flange portion 213 and can be attached to the opening O4 of the jar container 4 (see FIG. 3). The standing wall 214 in this embodiment is substantially semi-cylindrical, and in the left-right direction of the paper, it has a straight portion 214S that is straight in a plan view. The standing wall 214 also has an open portion S at the bottom of the paper in FIG. 2 that is cut out up to the opening O3 of the refill container body 2 (up to the upper end of the peripheral wall portion 21). The standing wall 214 also has a first undercut portion (protruding portion) 214a formed on the inner circumferential surface thereof, which protrudes radially inward of the refill container body 2 above the through-hole 213a and can be engaged with the opening O4 of the jar container 4.

[0019] The inner plate 22 is disposed in the refill container body 2 and is slidable from the bottom 211 side of the refill container 1 to the opening O3 side. The inner plate 22 includes a disk-shaped top wall portion 221, a cylindrical inner tube portion 222 extending downward from the top wall portion 221, and a contact portion 223 formed radially outside the inner tube portion 222 continuous with the top wall portion 221, protruding radially outward from the top wall portion 221, and slidably contacting the inner circumferential surface of the refill container body 2.

[0020] A rib 224 for reinforcing the inner plate 22 is provided on the lower surface side of the top wall portion 221.

[0021] The contact portion 223 is formed to be elastically deformable by being thinner than the top wall portion 221 and the inner cylinder portion 222, and is configured with a ring-shaped support arm 223a that extends diagonally downward from the peripheral edge of the top wall portion 221 and then bends and extends horizontally from the middle, and a drum-shaped contact arm 223b formed continuously with the tip of the support arm 223a. An upper end 223c and a lower end 223d of the contact arm 223b are configured to be slidably attached to the inner circumferential surface of the refill container body 2, respectively.

[0022] As shown in the figure, the contents C are contained in the space defined between the peripheral wall portion 21 and the top wall portion 221 when the inner plate 22 is disposed in the refill container body 2. As described above, the upper end portion 223c and the lower end portion 223d of the contact arm 223b are in close contact with the inner peripheral surface of the refill container body 2, thereby preventing the contents C contained in the refill container body 2 from leaking out from between them.

[0023] The sealing member 3 is composed of an annular seal 32 having an opening O2 with an inner diameter smaller than the opening O3 of the refill container 1, and a sealing seal 31 that covers the opening O2 of the annular seal 32 and is peelably attached to the annular seal 32.

[0024] In this embodiment, the annular seal 32 has an outer diameter approximately equal to that of the peripheral wall portion 21 , and is attached onto the flange portion 213 .

[0025] The sealing seal 31 includes a seal body 311 that is substantially circular in plan view and is peelably attached to the upper surface of the annular seal 32. The opening O2 of the annular seal 32 is covered by the seal body 311, so that it is possible to prevent the contents C contained in the refill container body 2 from coming into contact with the outside air. The seal body 311 is formed with a knob portion 312 that is rectangular in plan view and serves as a knob when a user peels off the sealing seal 31, at the right side of the paper in Figs. 1 and 2, with a length that protrudes outside the standing wall 214.

[0026] FIG. 3 shows a jar container 4 to be refilled with the contents C from the refill container 1 according to the embodiment of the present invention, (a) being a plan view and (b) being a front sectional view.

[0027] As shown in Fig. 3, the jar 4 is a bottomed cylindrical container having a bottom 41 and a cylindrical sidewall 42 extending upward from the periphery of the bottom 41, with an opening O4 formed at the top. The upper part of the sidewall 42 is a reduced diameter part 421 whose outer diameter is reduced compared to the lower part, and the boundary between the reduced diameter part 421 and the part of the sidewall 42 below that has no reduced diameter is a step part 422. The step part 422 is formed into wide step parts 422S on the left and right sides of the paper surface of Fig. 3(a).

[0028] A threaded portion 421a that screws into a lid (not shown) is formed on the outer circumferential surface of the reduced diameter portion 421. Furthermore, a second undercut portion 421b that can be engaged with the first undercut portion 214a of the refill container 1 is formed on the outer circumferential surface of the reduced diameter portion 421 above the threaded portion 421a on the side where the wide step portion 422S is provided (the left and right sides of the paper surface in FIG. 3(a)).

[0029] When transferring the contents C from such a refill container 1 to the jar container 4, the user first pinches the tab 312 of the sealing seal 31 and pulls it up. This allows the sealing seal 31 to be peeled off from the refill container 1 as shown in Figure 4. At this time, the annular seal 32 remains attached to the flange portion 213.

[0030] The refill container 1 with the sealing seal 31 shown in FIG. 4 peeled off is attached to the jar container 4 described above. FIG. 5 is a front cross-sectional view showing the state in which the refill container 1 according to the embodiment of the present invention is attached to the jar container 4. As shown in FIG. 5, the refill container 1 with the sealing seal 31 peeled off is attached to the jar container 4 in an inverted state with the upright wall 214 facing downward, so that the upright wall 214 covers the upper part of the reduced diameter part 421 of the jar container 4 from the outside. In this embodiment, the refill container 1 is attached to the jar container 4 so that the upper end of the reduced diameter part 421 contacts the flange part 213. However, for example, the outer diameter of the annular seal 32 may be increased so that the upper end of the reduced diameter part 421 contacts the annular seal 32. At this time, the first undercut part 214a of the refill container 1 is engaged with the second undercut part 421b of the jar container 4, and the refill container 1 is held by the jar container 4. The refill container 1 may be attached to the jar container 4 by moving the refill container 1 vertically toward the bottom 41 of the jar container 4 (at this time, the upright wall 214 of the refill container 1 elastically deforms and expands radially outward, causing the first undercut portion 214a of the refill container 1 to overcome and engage with the second undercut portion 421b of the jar container 4), or by moving the refill container 1 horizontally from the side of the open portion S formed in the upright wall 214 toward the reduced diameter portion 421 of the jar container 4.

[0031] Next, the content C of the refill container 1 is pushed out into the jar container 4 by operating the inner plate 22. FIG. 6 is a front cross-sectional view showing a state in which the inner plate 22 of the refill container 1 is slid into the opening O3 of the refill container 1 from the state shown in FIG. 5 to transfer the content C in the refill container 1 to the jar container 4. As shown in FIG. 5, for example, a user presses a finger F against the rib 224 of the inner plate 22, and then, as shown in FIG. 6, inserts the finger F into the opening O1 formed in the bottom 211 of the refill container 1 and pushes the inner plate 22 toward the bottom 41 of the jar container 4, so that the inner plate 22 slides toward the bottom 41, and the content C in the refill container 1 can be pushed out into the jar container 4 through the opening O2 of the annular seal 32. As described above, the inner plate 22 is provided with an elastically deformable abutment portion 223, and the upper end 223c and the lower end 223d of the abutment arm 223b are in close contact with the inner circumferential surface of the refill container body 2, respectively. Therefore, when the inner plate 22 is slid, the upper end 223c and the lower end 223d scrape off the contents C adhering to the inner surface of the refill container body 2, so that almost no contents C remains on the inner surface of the refill container body 2.

[0032] As the inner plate 22 is slid, the top wall 221 comes into contact with the annular seal 32. In this state, the contents C of the refill container 1 are almost entirely pushed into the jar 4. Furthermore, as the top wall 221 comes into contact with the annular seal 32, a load greater than the load applied by the finger F when pushing the inner plate 22 is applied. In other words, the user can know that the transfer of the contents C is complete even when the refill container 1 is attached to the jar 4 (the inside of the jar 4 cannot be seen). Furthermore, the annular seal 32 can prevent the inner plate 22 from falling off the refill container body 2.

[0033] Depending on the viscosity of the contents C, etc., the contents CR may remain in the opening O3 of the refill container 1 as shown in Fig. 6. In such a case, the remaining contents CR can be transferred to the jar container 4 by the method described below.

[0034] FIG. 7 is a side cross-sectional view showing how the contents CR remaining in the opening O3 of the refill container 1 are wiped off by sliding the refill container 1 with the open part S side facing backward in the moving direction after the contents C in the refill container 1 are transferred to the jar container 4. After the contents C are transferred to the jar container 4 (see FIG. 6), the contents CR remaining in the opening O3 of the refill container 1 are wiped off by the side wall 42 (reduced diameter part 421) of the jar container 4 by sliding the refill container 1 horizontally with the open part S side of the standing wall 214 facing backward in the moving direction, as shown in FIG. 7. The contents CR wiped off by the side wall 42 fall to the bottom part 41 side along the inner circumferential surface of the side wall 42. In this way, the contents CR remaining in the opening O3 of the refill container 1 can be collected and transferred to the jar container 4 without being wasted.

[0035] According to the refill container 1 according to the embodiment described above, the content C in the refill container 1 can be transferred to the jar container 4 with a simple operation without leaving any content C in the refill container 1 remaining in the refill container 1.

[0036] The present invention is not limited to the refill container 1 according to the embodiment described above, and various modifications can be adopted. [Explanation of symbols]
