Summary of the Invention

Problems to be Solved by the Invention

[0004] In Patent Document 1, a lever is added to a discharge container that discharges by raising and lowering a nozzle portion in order to improve ease of holding, ease of pressing, and non-slip properties. However, it is difficult to assemble an overcap that covers the nozzle portion and a stopper that regulates depression, and it is unsuitable for carrying and storage.

[0005] An object of the present invention is to provide a discharge container having a lever and a liftable nozzle portion that is suitable for carrying and storage.

Means for Solving the Problems

[0006] The first means includes a container body 2 having a mouth-neck portion 6, a mounting cap 10 that is externally fitted to the mouth-neck portion 6 and has a communication port 17 with an upward opening, A nozzle part 20 that communicates with the container body 2 via the communication port 17 and is arranged above the mouth-neck part 6 so as to be vertically movable in an upwardly biased state; A support part 18 erected from one side in the radial direction X of the mounting cap 10; A lever 30 pivotally attached to the support part 18 so as to be vertically movable, and protruding from the support part 18 to the other side in the radial direction X via the vicinity of the nozzle part 20. The discharge container is provided with a linking shaft 28 that links the nozzle part 20 to the lever 30 so as to be interlocked therewith. In a discharge container provided with a linking shaft 28 that links the nozzle part 20 to the lever 30 so as to be interlocked therewith, An over-cap 40 that also serves as a stopper and covers the nozzle part 20 is detachably mounted on the mounting cap 10 so as to be interposed between the lever 30 and the nozzle part 20. The over-cap 40 has a bearing hole 48 that holds the linking shaft 28 so as to be non-vertically movable, and is cut so that the linking shaft 28 can be led therethrough downward from the bearing hole 48.

[0007] In this means, as shown in FIG. 1, it has a nozzle part 20 that communicates with the container body 2 via the communication port 17 of the mounting cap 10 externally fitted to the mouth-neck part 6 of the container body 2, and is arranged above the mouth-neck part 6 so as to be vertically movable in an upwardly biased state. A lever 30 is projected from a support part 18 erected from one side in the radial direction X of the mounting cap 10, and a linking shaft 28 that links the nozzle part 20 to the lever 30 is provided. An over-cap 40 that is interposed between the lever 30 and the nozzle part 20 and covers the nozzle part 20 is detachably mounted on the mounting cap 10. According to this structure, since the over-cap 40 that covers the nozzle part is interposed between the lever 30 and the nozzle part 20, it is suitable for storage. Further, this over-cap 40 also serves as a stopper, has a bearing hole 48 that holds the linking shaft 28 so as to be non-vertically movable, and is cut so that the linking shaft 28 can be led therethrough downward from the bearing hole 48. According to this structure, it is possible to prevent the nozzle part from colliding with other objects during carrying and the content from being unexpectedly ejected, and it is suitable for carrying.

[0008] The second means has the first means, and the overcap 40 has a cut 50 extending at least from the lower edge of its outer peripheral wall 44 to the bearing hole 48, and an operation portion 54 connected to the outer peripheral wall 44. The width Wa of the cut 50 is narrower than the shaft diameter D of the connecting shaft 28. By pressing the operation portion 54 to deform the outer peripheral wall 44, the cut 50 is widened so that the connecting shaft 28 can be passed through.

[0009] In this means, as shown in FIG. 2, the overcap 40 has a cut 50 extending at least from the lower edge of its outer peripheral wall 44 to the bearing hole 48, and an operation portion 54 connected to the outer peripheral wall 44. And the width Wa of the cut 50 is narrower than the shaft diameter D of the connecting shaft 28. By pressing the operation portion 54 to deform the outer peripheral wall 44, the cut 50 is widened so that the connecting shaft 28 can be passed through. According to this structure, the overcap 40 can be removed by a simple operation of pressing the operation portion 54.

[0010] The third means has the second means, and the nozzle portion 20 is connected to the lever 30 via a pair of the connecting shafts 28 arranged on the side Y orthogonal to the radial direction X. The overcap 40 is formed with a pair of the bearing holes 48 corresponding to the respective connecting shafts 28, and a hinge portion 52 is formed between the tip portions 51 of the pair of the cuts 50 extending from the lower edge of the outer peripheral wall 44 beyond the respective bearing holes 48, thereby dividing the outer peripheral wall 44 into a first wall portion 44a and a second wall portion 44b. An operation portion 54 is erected with a pushing allowance a between the second wall portion 44b and the first wall portion 44a.

[0011] In this means, as shown in FIG. 2(B), the overcap 40 is formed with a pair of the bearing holes 48, and is provided with a pair of the cuttings 50 that extend from the lower edge of the outer peripheral wall 44 beyond each of the bearing holes 48. Then, the tip portions 51 of these cuttings are made adjacent to each other, and a hinge portion 52 is formed between the tip portions 51. By doing so, the outer peripheral wall 44 is divided into a first wall portion 44a and a second wall portion 44b, and the operation portion 54 is erected from the second wall portion 44b with a pushing allowance a existing between the first wall portion 44a. According to this structure, since the first wall portion 44a and the second wall portion 44b are continuous via the hinge portion 52, the cutting 50 can be efficiently widened by applying a force to the operation portion 54.

[0012] The fourth means has the third means, and the hinge portion 52 is disposed at an intermediate portion in the vertical direction of the outer peripheral wall 44. The first wall portion 44a has a concave wall portion 46 that is recessed inward of the outer peripheral wall 44 above the hinge portion 52. The operation portion 54 is erected in a plate shape from the hinge portion 52.

[0013] In this means, as shown in FIG. 2(A), the hinge portion 52 is disposed at an intermediate portion in the vertical direction of the outer peripheral wall 44. Further, the first wall portion 44a has a concave wall portion 46 that is recessed inward of the outer peripheral wall 44 above the hinge portion 52. And the operation portion 54 is erected in a plate shape from the hinge portion 52. According to this structure, the overcap 40 does not become bulky and can be disposed neatly between the nozzle portion 20 and the lever 30.

Effect of the Invention

[0014] According to the present invention, in a container that discharges by pushing down a nozzle portion by a lever operation, carrying and storage can be made good.

BEST MODE FOR CARRYING OUT THE INVENTION

[0016] FIGS. 1 to 4 show a discharge container according to an embodiment of the present invention. This discharge container includes a container body 2, a mounting member 8, a pump 19, a nozzle portion 20, a lever 30, and an over cap 40. These members can be formed of, for example, a synthetic resin material or metal. The discharge container of this embodiment is a spray container, but its structure can be appropriately changed.

[0017] The container body 2 has a mouth-neck portion 6 erected from a body portion 4 via a shoulder portion 5. An external thread portion m is formed on the outer surface of the mouth-neck portion 6. In the illustrated example, the upper end of the mouth-neck portion 6 is in contact with the lower surface of an inward flange 14 described later via a packing q. However, these structures can be appropriately changed.

[0018] The mounting member 8 is composed of a mounting cap 10 externally fitted to the mouth-neck portion 6 and a support portion 18 erected from the mounting cap 10. In the illustrated example, the mounting cap 10 and the support portion 18 are integrally connected, but their structure can be appropriately changed.

[0019] The mounting cap 10 is externally fitted to the mouth-neck portion 6 and has a communication port 17 for communicating the inside of the container body 2 with the nozzle portion 20. In the present embodiment, the mounting cap 10 is formed by erecting a standing cylinder portion 16 from the upper end of a mounting cylinder portion 12 fitted to the outer surface of the mouth-neck portion 6 via an inward flange 14. This standing cylinder portion 16 is a communication cylinder for communicating the inside of the container body 2 with the nozzle portion 20, and has a communication port 17 opening at its upper end. On the inner surface of the mounting cylinder portion 12, a female screw portion n that engages with the male screw portion m is formed. In the illustrated example, the standing cylinder portion 16 of the figure stands up a small-diameter cylinder portion 16c from a large-diameter cylinder portion 16a connected to the inward flange 14 via an upward circumferential step portion 16b. This small-diameter cylinder portion 16c is a guide cylinder portion for guiding the lifting of the nozzle portion 20. However, these structures can be changed as appropriate. Also, in the illustrated example, a hanging cylinder c is vertically provided from the lower end of the small-diameter cylinder portion 16c via an inner rib b. The upper end portion of a cylinder о described later is clamped between this hanging cylinder c and the large-diameter cylinder portion 16a.

[0020] The support portion 18 is a portion for supporting the lever 30 and is erected from one side (rear side) in the radial direction X (front-rear direction) of the mounting cap 10. And a portion (pivoting portion P) for pivoting with the lever 30 is formed on the upper side of the support portion 18. In this specification, for convenience of explanation, the right side of FIG. 1 is referred to as "rear", the left side as "front", and the direction orthogonal to the paper surface direction as "left and right". As shown in FIG. 3, the support portion of the present embodiment is formed as a horizontally wide and vertically long support piece in the left-right direction Y, and a pair of left and right shaft portions r are attached to the upper end portion of the support piece. Also, the front surface f of the support portion 18 is formed as a flat vertical surface. However, these structures can be changed as appropriate.

[0021] The pump 19 is a conventionally well-known one and is built in the container body 2. It has a cylinder that hangs down from the inward flange 14 of the mounting cap 10, and a stem k biased upward projects upward from this cylinder in a vertically movable manner.

[0022] The nozzle part 20 is guided in a vertically movable manner by the guide cylinder part 16c and is biased upward by an appropriate method (in this embodiment, by being connected to the stem k). On the outer peripheral surface of the nozzle part 20, a pair of bosses (link shafts 28) for being inserted into the second receiving holes 34 of the lever 30 described later are arranged in the left-right direction Y and are attached (see FIG. 3). The link shafts 28 and the second receiving holes 34 form a linking means L. Through this linking means L, the nozzle part 20 is linked to the lever 30 in a vertically interlocking manner. However, the configuration of the linking means L can be appropriately changed. In this embodiment, the nozzle part 20 is composed of a nozzle main body 21 and a known element 29 for spraying the content. The nozzle main body 21 is formed in a double-cylindrical shape composed of an outer cylinder wall 22 and an inner cylinder wall 26 that are connected to each other on the upper end side. In the illustrated example, the outer cylinder wall 22 is formed in a tapered cylindrical shape with a small diameter at the upper end, and the inner cylinder wall 26 is formed in a straight cylindrical shape. And the lower end part of the inner cylinder wall 26 is fitted (including loose fitting) to the inner surface of the guide cylinder part 16c, and the lower end part of the outer cylinder wall 22 is fitted to the outer surface of the guide cylinder part 16c. Also, the upper end parts of these two cylinder walls are connected to an end wall 23 having a nozzle hole 24 which is a spray hole. The element 29 is an elongated cylinder with a top that is fitted inside the inner cylinder wall 26. A horizontal hole h is opened in the upper part of the cylinder, and a groove e for communicating the horizontal hole h with the nozzle hole 24 is formed between the upper part of the cylinder and the nozzle main body 21. However, these structures can be appropriately changed.

[0023] The lever 30 is a member pivotally attached to the support part 18 so as to be vertically movable, and projects forward from the support part 18 through the vicinity of the nozzle part 20. In the illustrated example, as shown in FIG. 1, the lever 30 includes a base portion 30a that extends horizontally forward from the support portion 18 without any force applied, and a tip portion 30b that extends downward and forward from the base portion 30a. As shown in FIG. 1, the base portion 30a has an insertion window 38 described later for inserting the nozzle portion 20 and the overcap 40. This insertion window 38 is opened in the upper plate 36 of the lever 30 described later. The lever 30 is formed by connecting the upper ends of a pair of left and right side plates 32 shaped like the Chinese character "ㄑ" when viewed from the side (in the left - right direction Y) with an upper plate 36. The side plate 32 is provided with a first receiving hole 33 for pivotally fitting the shaft portion r of the support portion 18 and a second receiving hole 34 for loosely fitting the coupling shaft 28 of the nozzle portion 20. And, it is formed so that the nozzle portion 20 can be moved up and down by the swinging of the lever 30 around the pivot portion P. As long as this function can be ensured, the shaft portion r, the coupling shaft 28, the first receiving hole 33, and the second receiving hole 34 can have any structure. A gap is provided between the side plate 32 and the nozzle portion 20 for interposing the outer peripheral wall 44 of the overcap 40 described later.

[0024] The insertion window 38 is opened in the upper plate 36. This insertion window 38 is a part for inserting the nozzle portion 20 and the overcap 40. The insertion window 38 in the illustrated example is formed as an elongated hole that is long in the front - rear direction corresponding to the shape of the overcap 40 when viewed from above. As shown in FIG. 1, a gap g is provided between the insertion window 38 and the overcap 40 to enable insertion and removal of the overcap 40 into the insertion window 38. In the illustrated example, as shown in FIG. 4(A), a portion g1 between the overcap 40 and the front side (the side opposite to the pivot portion P) of the insertion window 38 in the gap is set larger than the remaining portion g2. This is for swinging the first wall portion 44a of the outer peripheral wall 44 of the overcap 40 described later forward when removing the overcap 40 upward (see FIG. 4(B)).

[0025] The over cap 40 is a member having a cap function of covering the nozzle portion 20 and a stopper function of preventing the nozzle portion 20 from moving up and down. The over cap 40 is interposed between the lever 30 and the nozzle portion 20 inside the insertion window 38 and is attached and fixed to the mounting cap 10. Further, the over cap 40 is detachably mounted at an appropriate position of the mounting cap 10 (the upper surface of the inward flange 14 in this embodiment). As shown in FIG. 2(A), the over cap 40 has a bearing hole 48 for holding the linking shaft 28 so as not to move up and down, and is cut so that the linking shaft 28 can be led downward from the bearing hole 48. Therefore, as shown in FIG. 4(A), even when the lever 30 is pulled in a state where the over cap 40 is mounted on the mounting cap 10, the linking shaft 28 in the bearing hole 48 cannot descend, and the above-described stopper function is ensured.

[0026] In this embodiment, as shown in FIG. 1, the over cap 40 includes a top plate 42, an outer peripheral wall 44 vertically provided from the peripheral edge of the top plate 42, and an operation portion 54 connected to a part of the outer peripheral wall 44. The over cap 40 is formed of an elastic material. As shown in FIG. 3, the outer peripheral wall 44 in the illustrated example is wider in the front-rear direction X than in the left-right direction Y and is a vertically long cylindrical body. Side surfaces S of this cylindrical body are a pair of left and right vertical surfaces, a front surface T is a curved surface bulging forward, and a rear surface U is formed as a substantially vertical surface, respectively. However, the upper half of the rear surface U is formed as a concave wall portion 46 that sinks forward via an upward step portion 52 with respect to the lower half. In this specification, the "concave wall portion" refers to a structure formed such that a part of the outer wall of an object is located inside other parts when viewed from the side. In this embodiment, the upward step portion 52 also serves as a hinge portion described later. Further, an operation portion 54 described later stands up from the upward step portion 52.

[0027] On each of the pair of side portions S, there are formed a bearing hole 48 through which the linking shaft 28 is inserted, and a cut 50 that is in contact with the bearing hole 48 and extends from the lower edge of the outer peripheral wall 44 to the upward step portion 52.

[0028] As shown in FIG. 4(A), the bearing hole 48 receives and holds the linking shaft 28 so as not to move up and down by contacting and locking to the linking shaft 28 at least on the upper side and the lower side of the hole edge. In the illustrated example, the rear side of the bearing hole 48 is continuous with the cut 50. As will be described later, in a state where the cut 50 is widened (see FIG. 4(B)), the linking shaft 28 can be led downward of the outer peripheral wall 44 by pulling up the overcap 40. This structure can be appropriately changed. For example, the front side of the bearing hole 48 may be continuous with the cut 50. Also, the bearing hole 48 in the illustrated example has a C-shaped (or semi-circular) edge along the linking shaft 28 that is circular in side view, excluding the rear side that is continuous with the cut 50.

[0029] The cut 50 is a notch portion having a constant width Wa in the form during molding. The cut 50 of the present embodiment, when viewed in the left-right direction Y, has a base half portion 50a extending from the lower edge of the outer peripheral wall 44 to the bearing hole 48, and a tip half portion 50b extending beyond the bearing hole 48 to the upward step portion 52. The base half portion 50a is a guiding passage for enabling the insertion and removal of the linking shaft 28 into the bearing hole 48, and the tip half portion 50b is an extension portion for enabling the widening of the cut 50 described later. However, the form of the cut 50 can be appropriately changed. As long as the outer peripheral wall 44 can be deformed in the radial direction X by operating the operation portion 54 and the cut 50, which is a guiding passage to the bearing hole 48, can be widened, any structure is acceptable. In the illustrated example, the base half portion 50a becomes narrower from the lower side to the upper side in the initial state shown in FIG. 4(A). Let the width at the narrowest part of the cut 50 (the upper end of the base half 50a in the illustrated example) be Wa, the width of this part in the widened state described later be Wb, and the shaft diameter of the linking shaft 28 be D. Then, Wb ≧ D > Wa. By doing so, before the widening operation, the bearing hole 48 is prevented from being unexpectedly connected through the cut 50. And a part connecting the tip portions 51 of the pair of left and right cuts 50 (near the upward step portion 52 in the illustrated example) is formed to be deformable as a hinge portion. By doing so, the outer peripheral wall 44 is divided into a first wall portion 44a and a second wall portion 44b. One of these two wall portions (the first wall portion 44a in the illustrated example) is formed to be rotatable about the hinge portion 52 with respect to the other (the second wall portion 44b in the illustrated example) (see Fig. 4(B)). In the illustrated example, the first wall portion 44a is a main wall portion occupying most of the outer peripheral wall 44, and the second wall portion 44b is a sub-wall portion occupying the remaining part. And an operation portion 54 described later is erected by being continuously provided on the second wall portion 44b. However, these structures can be appropriately changed. The rear surface i of the second wall portion 44b is in contact with the front surface f of the support portion 18. In the present embodiment, the operation portion 54 is a vertical operation plate having a constant width in the left - right direction (the same width as the outer peripheral wall 44 in the illustrated example). In the illustrated example, the upper end of the operation plate is flush with the upper surface of the top plate 42, and the rear surface j of the operation plate is flush with the rear surface i of the second wall portion 44b.

[0030] The hinge portion 52 may be a thin - wall hinge, but in the illustrated example, it has a certain thickness, and by an operation of pushing the operation portion 54, the hinge portion 52 elastically deforms so that the cut 50 expands. By doing so, when the user pushes the operation portion 54, the cut 50 can be easily expanded, but when carrying the discharge container in a bag or the like, the cut 50 does not expand even if another object touches the operation portion 54 to such an extent (therefore, the locking state of the linking shaft 28 to the bearing hole 48 is not released).

[0031] The operation part 54 extends upward so as to face the rear surface of the upper half of the first wall part 44a with a pushing-in allowance a existing between it and the hinge part 52. When performing the widening operation of the cutter 50, as indicated by the arrow in FIG. 4(B), the upper part of the front part T of the first wall part 44a and the rear surface j of the operation part 54 may be pinched with fingers. Then, since the second wall part 44b is in contact with the front surface of the support part 18, the first wall part 44a and the top plate 42 swing forward about the hinge part 52, and the cutter 50 is widened. Although not shown in the figure, the first wall part 44a may be configured not to move and the second wall part 44b may be configured to swing backward by pushing the operation part 54 forward.

[0032] In the initial state shown in FIGS. 1 and 4(A) in the above configuration, the overcap 40 covers the nozzle part 20 and protects its tip part. And in the state where the overcap 40 covers the nozzle part 20, since the linking shaft 28 of the nozzle part 20 is locked in the bearing hole 48 of the overcap 40, the protection state of the tip part of the nozzle part 20 is maintained unless an operation of intentionally pushing the operation part 54 (pinching the operation part 54 and the front part of the outer peripheral wall 44 in the illustrated example) is performed. Therefore, the overcap 40 will not accidentally come off during carrying the ejector in a bag or the like, which is convenient for carrying. Also, the linking shaft 28 of the nozzle part 20 is held in the bearing hole 48 of the overcap 40 so as not to move up and down, and the overcap 40 is mounted on the inward flange 14 of the mounting cap 10. Therefore, the lever 30 cannot be pulled, and the stopper function is ensured. When using the container, the upper part of the first wall part 44a of the overcap 40 and the operation part 54 are pinched with fingers. Then, since the cutter 50 widens, the overcap 40 can be pulled out from the insertion window 38 by just pulling up the overcap 40. Then, when the lever 30 is pulled, the content is sprayed from the nozzle hole 24 by the action of the pump 19. When finished using, the upper part of the first wall part 44a of the overcap 40 and the operation part 54 are pinched with fingers again. After widening the cut 50 in this way, the overcap 40 is inserted into the insertion window 38 from above, and by lowering the overcap 40 while avoiding the linking shaft 28, the linking shaft 28 is made to enter into the cut 50. When the overcap 40 is inserted until it abuts against the inward flange 14, the linking shaft 28 is positioned at the same height as the bearing hole 48. In this state, when the finger is released from the overcap 40, due to the elastic restoration of the outer peripheral wall 44, the cut 50 returns to its original width, the linking shaft 28 is locked within the bearing hole 48, and it returns to the original state.

[0033] According to the above configuration and operation, since an overcap 40 that also serves as a stopper for covering the nozzle portion 20 is provided, it is possible to prevent the nozzle portion from colliding with other objects during carrying and the contents from being unexpectedly ejected, and it is suitable for carrying. Also, since the cut 50 extending from the lower edge of the outer peripheral wall 44 of the overcap 40 to the bearing hole 48 for holding the linking shaft 28 of the nozzle portion 20 widens by pressing the operation portion 54 continuously provided on the outer peripheral wall 44, the overcap 40 can be easily removed. The outer peripheral wall 44 of the overcap 40 is divided into a first wall portion 44a and a second wall portion 44b by a pair of cuts 50 and a hinge portion 52 between the tip portions 51 of both cuts 50, and since the operation portion 54 is erected from the second wall portion 44b, the cuts 50 can be widened efficiently.
