Description

[Technical Field]

[0001] The present invention relates to an airless pump-type dispensing container that has an inner tray placed within the filling space of the container body, and that allows the contents to be dispensed without air replacement by raising the inner tray.

[0002] As disclosed in Patent Document 1, an airless type dispensing container is known in which, when a pump attached to the neck of the container body is driven to dispense the contents inside the container body, negative pressure is created inside the container body as the contents are dispensed, and a sliding bottom plate provided inside the container body rises by the volume of the dispensed contents, thereby preventing air from flowing into the container body when the contents are dispensed. Such airless type dispensing containers have advantages such as being able to prevent the contents from being soiled or deteriorating in quality due to oxidation because air is not replaced inside the container body when the contents are dispensed, and have been widely used in recent years as containers for high-end cosmetics. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2001-48216 Summary of the Invention [Problem to be solved by the invention]

[0004] The airless type dispensing containers as described above often have a small capacity, which leads to frequent replacement of the product, resulting in high costs and a large amount of plastic waste. Furthermore, the dispensing containers are configured so that the sliding bottom plate rises as the contents are dispensed, and therefore, in order to refill and use the contents, it is necessary to push the sliding bottom plate down to the bottom using a stick or the like, which makes the transfer of the contents time-consuming, and therefore the containers are usually in a single-use form.

[0005] Therefore, an object of the present invention is to provide an airless pump-type dispensing container that can be reused by refilling (refilling) the contents. [Means for solving the problem]

[0006] The pump-type discharge container of the present invention, which has been developed to achieve the above object, comprises: a container body having a filling space for filling the contents; a pressure head attached to the neck portion of the container body, which operates a pump mechanism suspended within the neck portion by repeatedly pressing the head body, thereby discharging the contents filled in the filling space through a discharge hole; an inner tray that is slidably disposed within the filling space of the container body and that slides to reduce the filling space as the contents filled in the filling space are discharged; A pump-type discharge container comprising: an under member attached to an open end of the container body that exposes the inner tray disposed in the filling space at a bottom portion thereof, the under member having a cylindrical body with a passage formed therein that communicates with the filling space; a skirt member provided at a lower portion of the under member, the skirt member having a cylindrical portion and a bottom wall that can be detachably attached to the cylindrical body, the skirt member contacting the bottom wall to hold the container body in an upright position; the cylindrical body allows the pressing head, which has been removed from the neck portion of the container body, to be replaced; The skirt member is characterized in that it holds the container body in an inverted position by removing the cylindrical portion from the cylindrical body and replacing it with the neck portion of the container body.

[0007] It is also preferable that the cylindrical portion comprises an inner cylindrical portion that is detachably attached to the cylindrical body when the container body is in an upright position, and an outer cylindrical portion that can abut against the end of the outer wall of the under member.

[0008] Furthermore, in the pump-type dispenser of the present invention, it is preferable that the bottom wall has an outside air inlet tube that rises along the side wall of the inner cylindrical portion inside the inner cylindrical portion and sends outside air into the container body excluding the filling space through a through path.

[0009] Furthermore, in the pump-type discharge container of the present invention, it is preferable that the inner plate has a recess formed on the surface that allows the suction part of the pump mechanism to be inserted, and an annular recess formed on the back that allows the annular protrusion provided on the under member to be inserted.

[0010] Furthermore, in the pump-type discharge container of the present invention, it is preferable that the inner plate has a ring-shaped body that can abut against the end portion of the neck portion and the end portion of the cylindrical body, respectively, and has a cross-sectional shape that is symmetrical with respect to a line perpendicular to the axis of the container body. [Effects of the Invention]

[0011] In the pump-type discharge container of the present invention, the pressing head equipped with the pump mechanism and the skirt member that holds the pump-type discharge container in an upright position (upright position and inverted position) are each configured to be detachable from both the neck portion of the container body and the cylindrical body of the under member attached to the open end of the container body, so that the pressing head and skirt member can be removed and replaced with the neck portion of the container body and the cylindrical body of the under member for use.

[0012] Therefore, with the pump-type discharge container of the present invention, when the contents have been used up (when the inner tray has risen to the upper end position of the container body), the pressing head attached to the neck portion of the upright container body and the skirt member attached to the cylindrical body of the under member can be removed, and the container body can be inverted to position the inner tray at the lower end of the container body, thereby securing a filling space for the contents, and by attaching the skirt member to the neck portion located below, the contents can be refilled into the filling space from the cylindrical body located above.

[0013] Therefore, unlike conventional airless pump-type dispensing containers, there is no need to use a rod-shaped member or the like to push down the inner tray that has risen to the top end of the container body in order to refill the contents.By switching the container body between an upright position and an inverted position and replacing the pressing head and skirt member, the contents can be easily refilled into the filling space of the container body, and the dispensing container can be used repeatedly.

[0015] An embodiment of the present invention will be described with reference to the drawings. Fig. 1 is a diagram showing a pump type discharge container according to an embodiment of the present invention, where (a) is a plan view and (b) is a cross-sectional view taken along line AA in (a). Fig. 2 is a diagram illustrating a process of replacing the pressing head and skirt member with the container body in the inverted position in the pump type discharge container of Fig. 1. Fig. 3 is a diagram showing a pump type discharge container in the inverted position of the container body of Fig. 2. The pump-type discharge container according to the present invention can be used repeatedly by inverting the container body and replacing the pressing head and skirt member, as described below. The following description will be given assuming that the container body shown in Figure 1 is in an upright position and that the container body shown in Figure 3 is in an inverted position.

[0016] In Figures 1(a) and (b), reference numeral 1 denotes a cylindrical container body having a filling space M inside which the contents are filled. Reference numeral 2 denotes a pressing head detachably attached to the neck portion 12 of the container body 1. Reference numeral 3 denotes an inner plate that is slidably disposed within the filling space M of the container body 1 and slides upward to reduce the filling space M as the contents filled in the filling space M are discharged. Reference numeral 4 denotes an under member detachably attached to an open end 14 provided at the bottom end of the container body 1. Reference numeral 5 denotes a skirt member that is provided below the under member 4 and holds the pump-type discharge container in an upright position.

[0017] The container body 1 has a cylindrical body 11 and a cylindrical neck portion 12 provided at the upper end of the body 11. In this embodiment, the body 11 is shown as being cylindrical, but this is not limiting, and the shape of the body 11 can be modified as appropriate. In this embodiment, the neck portion 12 has a male thread 12a on the outer circumferential surface thereof, and the base cap 21 of the pressing head 2 and the inner cylindrical portion 52 of the skirt member 5, which will be described later, are threadedly engaged with the male thread 12a, thereby enabling the pressing head 2 and the skirt member 5 to be detachably attached. Note that the pressing head 2 and the skirt member 5 may be attached to the neck portion 12 using other fixing means, such as undercut fitting, instead of threading.

[0018] The pressing head 2 has a base cap 21 with a female thread 21a on its inner peripheral surface and a cover 27 that surrounds the base cap 21 and engages with the base cap 21 so as not to be rotatable, and can be detachably attached to the container body 1 by screwing the base cap 21 onto the male thread 12a provided on the outer peripheral surface of the mouth / neck portion 12 of the container body 1. Note that the pressing head 2 may be attached to the container body 1 using other fixing means, such as undercut fitting, instead of screwing.

[0019] The pressing head 2 is equipped with a pump mechanism 22 that is suspended inside the neck portion 12. A head body 23 is attached to the pump mechanism 22, and when the head body 23 is repeatedly pressed, a piston 24 arranged inside the pump mechanism 22 is driven, and the contents filled in the filling space M of the container body 1 are sucked through a suction part 25, and are pressurized and compressed, so that they can be discharged from a nozzle 26 (discharge hole) of the head body 23.

[0020] The pump mechanism 22 is not limited to the one shown in the figure, and any configuration can be applied as long as it does not suck in air from the outside when the contents are discharged by pressing the head body 23, and negative pressure is created inside the container body 1 as the contents are discharged, causing the inner tray 3 provided inside the container body 1 to be sucked in and slide up inside the container body 1.

[0021] The inner plate 3 is pressed against the inner circumferential surface of the barrel 11 of the container body 1, and functions as a partition dividing the container body 1 into a filling space M (upper side) for the contents and an area (lower side) below the inner plate 3. The inner plate 3 is made up of an outer cylindrical portion 31 that is slidable in close contact with the inner circumferential surface of the barrel 11 of the container body 1, and an inner cylindrical portion 33 that is integral with the outer cylindrical portion 31 by a flange portion 32 provided at the upper end of the outer cylindrical portion 31. The inner plate 3 is preferably made of a flexible material such as synthetic resin so that it can be pressed against the inner circumferential surface of the barrel 11 of the container body 1 and slidably thereon.

[0022] The outer cylinder 31 is configured with an upper edge 31a and a lower edge 31b to be in close contact with the inner circumferential surface of the body 11. The inner cylinder 33 has a recess 34 on its surface into which the suction part 25 of the pump mechanism 22 is inserted when the inner plate 3 slides up within the container body 1 as the contents are discharged as described above.

[0023] The inner tray 3 has an annular recess 35 formed between the outer cylindrical portion 31 and the inner cylindrical portion 33 on the back surface thereof, and an annular protrusion 46 of the under member 4 (described later) can be inserted into the annular recess 35. The inner tray 3 also has a cylindrical hanging portion 36 hanging down from the bottom edge of the inner cylindrical portion 33 on the back surface thereof. When the inner tray 3 slides up inside the container body 1 in the inverted position of the container body 1 shown in FIG. 3 , the suction portion 25 of the pressing head 2 attached to the cylindrical body 45 of the under member 4 (described later) is inserted into the hanging portion 36.

[0024] At the upper end position within the container body 1, the inner plate 3 is configured so that the upper edge 31a of the outer tube 31 and the upper end of the flange 32 abut against the inner wall surface of the shoulder 15 connecting the barrel 11 and the neck 12 of the container body 1, and the suction part 25 of the pump mechanism 22 abuts against the recess 34 of the inner plate 3. At the lower position within the container body 1, the lower edge 31b of the outer tube 31 abuts against the upper end of a first inner tube 42 of the under member 4, which will be described later, thereby restricting downward movement of the inner plate 3.

[0025] The under member 4 is composed of an outer cylindrical portion 41, a first inner cylindrical portion 42 located radially inside the outer cylindrical portion 41, connected to the lower end of the outer cylindrical portion 41 via a flange, and erected toward the inner tray 3, a second inner cylindrical portion 43 located radially inside the first inner cylindrical portion 42, connected to the lower end of the first inner cylindrical portion 42 via a flange, and erected toward the inner tray 3, a third inner cylindrical portion 44 located radially inside the second inner cylindrical portion 43, connected to the upper end of the second inner cylindrical portion 43, and extending downward, and a cylindrical body 45 suspended from the lower end of the third inner cylindrical portion 44. The cylindrical body 45 has a passage communicating with the filling space M.

[0026] The under member 4 is attached so as to cover the open end 14 at the end of the body portion 11 by the inner surface of the outer tube portion 41 being undercut and fitted into a recess 13 provided on the outer surface of the lower end of the body portion 11 of the container body 1.

[0027] The under member 4 comprises a second inner cylindrical portion 43 and a third inner cylindrical portion 44 that form an annular convex portion 46. The annular convex portion 46 is inserted into the annular recess 35 of the inner tray 3 at the bottom end of the container body 1 in the upright position shown in Fig. 1 and at the top end of the container body 1 in the inverted position shown in Fig. 3, thereby enabling the inner tray 3 to be stably positioned in a desired position. In the pump-type discharge container shown in Figs. 1 to 3, it is preferable to appropriately change the cross-sectional shape of the inner tray 3 and the protrusion of the annular convex portion 46 so that the volume of the filling space M remains the same regardless of whether the container body 1 is in the upright or inverted position.

[0028] In this embodiment, the cylindrical body 45 has a male thread 45a on its outer peripheral surface, and the male thread 45a is threadedly engaged with a female thread 21a provided on the inner peripheral surface of the base cap 21 of the pressing head 2 and a female thread 52a provided on the inner peripheral wall of an inner cylindrical portion 52 of the skirt member 5, which will be described later. The pressing head 2 and the skirt member 5 may be attached and detached by other fixing means, such as undercut fitting, instead of threading.

[0029] The skirt member 5 is provided at the lower part of the under member 4 and includes a tube portion 50 composed of an outer tube portion 51 and a cylindrical inner tube portion 52, and a bottom wall 53 connected to the lower end of the outer tube portion 51 and the lower end of the inner tube portion 52. The inner tube portion 52 has a female thread 52a on its inner peripheral surface, which threads onto a male thread 45a on the outer peripheral surface of the tube body 45 of the under member 4 when the container body 1 is in the upright position shown in FIG. 1 , thereby enabling the skirt member 5 to be detachably attached to the under member 4. Note that when attached to the under member 4, the upper end of the outer tube portion 51 abuts against the lower end of the outer tube portion 41 of the under member 4. In this embodiment, the tube portion 50 is composed of the outer tube portion 51 and the inner tube portion 52, but is not limited thereto. The tube portion 50 may have any configuration as long as it has at least the inner tube portion 52 that is attached to the tube body 45 of the under member 4 when the container body 1 is in the upright position.

[0030] In addition, when the container body 1 is in the inverted position shown in Figure 3, the skirt member 5 is removably attached to the neck portion 12 by threading the female thread 52a of the inner tube portion 52 into the male thread 12a provided on the outer peripheral surface of the neck portion 12.

[0031] The bottom wall 53 is provided horizontally so that it can be placed on the floor or the like to hold the container body 1 in an upright position. The bottom wall 53 has an outside air introduction tube 54 that is configured to rise up along the inner surface of the inner tube portion 52 inside the inner tube portion 52. The outside air introduction tube 54 connects the space between the bottom wall 53 and the inner tray 3 with the outside, and sends outside air into the filling space M via a through-path 54a, thereby allowing the inner tray 3 to slide within the filling space M.

[0032] Further, reference numeral 6 denotes an overcap that covers the pressing head 2, and is composed of a cylindrical peripheral wall 61 and a top wall 62 connected to the upper end of the peripheral wall 61, and is attached detachably by undercut fitting the inner surface of the peripheral wall 61 to the pressing head 2.

[0033] The usage of the pump-type discharge container of this embodiment will be described below. In the pump-type discharge container having the above configuration, when discharging the contents, the head body 23 of the pressure head 2 is pressed to discharge the contents from the nozzle 26 (discharge hole) of the head body 23, and the inner tray 3 rises by that amount due to the negative pressure created inside the container body 1. When the discharge of the contents is completed, the inner tray 3 reaches the upper end position inside the container body 1 (inside the filling space M) as shown by the imaginary line in Figure 1.

[0034] From this state, as shown in Figure 2, the pressing head 2 is removed from the neck portion 12 of the container body 1, and the skirt member 5 is removed from the tubular body 45 of the under member 4. Next, the removed skirt member 5 is attached to the neck portion 12, and the container body 1 is inverted. By placing the container body 1 in the inverted position, the inner plate 3 is positioned below the container body 1, and a filling space M is formed between the inner plate 3 and the under member 4. Note that even if the contents (residual liquid) remaining in the filling space M flow down through the neck portion 12 into the skirt member 5 when the container body 1 is inverted, the outside air inlet tube 54 provided on the bottom wall 53 of the skirt member 5 is inserted inside the neck portion 12, so that the contents can be prevented from leaking into the container due to the flow down.

[0035] After filling the contents from the cylindrical body 45 of the under member 4 located at the upper side when the container body 1 is in an inverted position, the container can be reused as a pump-type discharge container by attaching the pressing head 2 to the cylindrical body 45 as shown in Figures 2 and 3. As described above, with the pump-type discharge container of this embodiment, the contents can be easily refilled by inverting the container body 1 and replacing the pressing head 2 and skirt member 5 with the neck portion 12 of the container body 1 and the cylindrical body 45 of the under member 4, and the discharge container can be used repeatedly.

[0036] With the container body 1 in the inverted position shown in Figure 3, when the head body 23 of the pressing head 2 is pressed down to discharge the contents from the nozzle 26 (discharge hole) of the head body 23, the inner tray 3 reaches the upper end position inside the container body 1 (inside the filling space M) as shown by the imaginary line in Figure 3 when the discharge of the contents is completed. At this time, the lower edge 31b of the inner tray 3 abuts against the first inner tube portion 42 of the under member 4, and the suction portion 25 of the pump mechanism 22 abuts against a recess in the hanging portion 36 of the inner tray 3, causing the inner tray 3 to stop rising.

[0037] FIG. 4 is a schematic diagram showing another embodiment of the pump type discharge container of the present invention. Hereinafter, explanations of the same parts as those in the previous embodiment will be omitted. In the pump-type discharge container of this embodiment, the container body 1 has a cylindrical body 110 and a neck portion 112 connected via a shoulder portion 111. The neck portion 112 has a male thread 112a on its outer circumferential surface, and is configured so that the base cap 21 of the pressing head 2 and the inner cylindrical portion 51 of the skirt member 5 can be screwed onto the male thread 112a, thereby allowing the pressing head 2 and the skirt member 5 to be detachably attached. In addition, the end portion 112b of the neck portion 112 is located below the shoulder portion 111.

[0038] The inner plate 3 has an outer tube portion 310 that is slidable in close contact with the inner surface of the barrel portion 110 of the container body 1, an annular plate portion 311 that is connected to the center position of the outer tube portion 310 in the direction of the container axis L and extends in a direction perpendicular to the container axis L, and a pair of annular bodies 312 that have a cross-sectional shape that is line-symmetrical with respect to the annular plate portion 311.

[0039] The under member 4 has an outer cylindrical portion 410, a flange portion 411 connected to the lower end of the outer cylindrical portion 410, an inner cylindrical portion 412 standing from the flange portion 411 toward the inner plate 3, and a cylindrical body 413 connected to the end of the flange portion 411 and having a passage communicating with the filling space M. The cylindrical body 413 has a male thread 413a on its outer peripheral surface, and the male thread 413a is screwed into a female thread 21a provided on the inner peripheral surface of the base cap 21 of the pressing head 2 and a female thread 52a provided on the inner peripheral surface of the inner cylindrical portion 52 of the skirt member 5, so that the pressing head 2 and the skirt member 5 can be detachably attached. In addition, the end portion 413b of the cylindrical body 413 is located above the flange portion 411 (toward the inner plate 3).

[0040] In the pump-type dispensing container having the above-described configuration, before the contents start to be dispensed as shown in Figure 4, the lower edge 310b of the outer tube portion 310 of the inner plate 3 abuts against the upper end of the inner tube portion 412 of the under member 4, and the lower end of the annular body 312 abuts against the end portion 413b of the tube body 413, thereby restricting the downward movement of the inner plate 3.

[0041] When the contents are dispensed, the head body 23 of the pressure head 2 is pressed to dispense the contents from the filling space M through the nozzle 26 (discharge hole) of the head body 23. The negative pressure within the container body 1 causes the inner plate 3 to rise accordingly, and when the contents are dispensed, the inner plate 3 reaches the upper end of the container body 1 (within the filling space M) as shown by the imaginary line in Figure 4. When the inner plate 3 reaches the upper end, the upper edge 310a of the outer tube 310 abuts against the rib 113 provided on the inner circumferential surface of the upper end of the barrel 110 of the container body 1, and the upper end of the annular body 312 abuts against the end portion 112b of the neck 112, thereby restricting its upward movement. The annular body 312 is configured so that the suction part 25 of the pump mechanism 22 can be inserted into the inner side of the annular body 312 when the inner plate 3 reaches the upper end of the container body 1.

[0042] In the pump-type dispensing container having the above configuration, after the inner plate 3 reaches the upper end position within the container body 1 and the dispensing of the contents is completed, the pressing head 2 is removed from the neck portion 112, the skirt member 5 is removed from the cylindrical body 413, and the skirt member 5 is reattached to the neck portion 112, and the container body 1 is inverted, whereby the skirt member 5 can hold the container body 1 upright in an inverted position, and the contents can be refilled into the filling space M of the container body 1 from the cylindrical body 413 located above, allowing the container to be used repeatedly.

[0043] In addition, in this embodiment, the inner plate 3 has a cross-sectional shape that is line-symmetrical with respect to the annular plate portion 311 extending in a direction perpendicular to the container axis L, and the neck portion 112 and the cylindrical body 413 have the same shape (same volume), so the volume of the filling space M can be made the same when the container body 1 is used in an upright position and an inverted position by switching the pressing head 2 and the skirt member 5. Furthermore, when setting the inner plate 3 in the container body 1 in the assembly process, there is no need to align it vertically, improving ease of setting. [Industrial Applicability]

[0044] The pump-type dispensing container according to the present invention can be suitably used as a container for dispensing contents such as cosmetics, pharmaceuticals, chemicals, etc., and can be reused by refilling the contents. [Explanation of symbols]
