Summary of the Invention

Problems to be Solved by the Invention

[0004] In the container of Patent Document 1, after mounting (closing) the upper lid body on the upper surface of the lower lid body and mounting the lower lid body on the upper surface of the cap body, the upper end of the pipe must be fitted into the fitting cylinder of the cap body and the cap body must be screwed to the neck portion. Therefore, the assembly procedure is troublesome and the setability is not good. Furthermore, when tilting the container to dispense the contents, one had to be careful about the orientation of the lid (the upper lid in the case of spraying) so that it was on the opposite side of the direction in which the container was tilted, which made it inconvenient to use.

[0005] The objective of the present invention is to provide a spray container that is easy to set and use. [Means for solving the problem]

[0006] The first means is a container body 2 having a mouth-neck portion 8 that rises from the body portion 4, A plug 10 is formed by integrally extending a pipe-shaped section 18 from the upper end of a first mounting cylinder 12 fitted to the outer surface of the neck portion 8, via a first flange-shaped wall 14, into the neck portion 8, A cap 20 is formed by erecting a shaft cylinder 28 with an air intake port 30 opening at the upper end, via a second flange-like wall 26, from the upper end side of the second mounting cylinder 22 which is fitted onto the outer surface of the first mounting cylinder 12, and by projecting upward from the second flange-like wall 26, a circumferential partition wall 34 that concentrically surrounds this shaft cylinder 28. A top-mounted cylindrical head member 40 is attached to the cap 20 by fitting a bearing cylinder 46, which extends vertically from the top plate 42, to the outer surface of the shaft cylinder 28 in a liquid-tight and rotatable manner, and the top plate 42 has a spray port о inside the bearing cylinder 46 that communicates with the air intake port 30, It is equipped with, A rotation-preventing means S is provided between the inner stopper 10 and the cap 20. The gap V between the neck portion 8 and the pipe portion 18 is connected to the liquid cabinet C formed between the shaft 28 and the circumferential partition wall 34 through a pair of communication holes h1 and h2 drilled in the first flange-like wall 14 and the second flange-like wall 26, respectively, A first fluid passage groove 32 is vertically provided on the outer surface of the shaft cylinder 28, and a second fluid passage groove 50 is vertically provided on the inner surface of the bearing cylinder 46. By rotating the head member 40, the first fluid passage groove 32 and the second fluid passage groove 50 are made continuous with each other, so that the fluid cabinet C communicates with the spray nozzle. Furthermore, a gas-liquid mixing section m is provided between the upper end surface of the shaft cylinder 28 and the lower surface of the top plate 42.

[0007] In this method, as shown in Figure 1, the first mounting cylinder 12 of the inner stopper 10 is fitted to the outer surface of the neck portion 8 of the container body 2, and the second mounting cylinder 22 of the cap 20 is fitted to the outer surface of the first mounting cylinder 12, and the bearing cylinder 46 of the head member 40 is rotatably fitted to the outer surface of the shaft cylinder 28 of the cap 20. Furthermore, since the pipe cylinder portion 18 is suspended from the first mounting cylinder 12 of the inner stopper 10 via the first flange-like wall 14, there is no need to attach the pipe cylinder portion 18 to the first flange-like wall 14 side, resulting in good set-up. Furthermore, when spraying the contents, only the head component 40 needs to be rotated, eliminating the need to pay attention to the orientation of the lid when spraying, as in conventional technology, making it easy to use.

[0008] The second means has the same properties as the first means, and the pipe portion 18 is suspended from the inside of the mouth neck portion 8 to the upper portion 4c of the body portion 4, and the lower part of the pipe portion 18 is a tapered portion 19 that narrows downwards.

[0009] In this method, as shown in Figure 1, the lower part of the pipe section 18 is made into a tapered section 19 that narrows downwards. This structure makes it less likely for liquid to enter the pipe section 18 when the device is inverted. [Effects of the Invention]

[0010] According to the present invention, a spray container with good set-up properties and ease of use can be provided. [Brief explanation of the drawing]

[0011] [Figure 1] This is a cross-sectional view of a spray container according to an embodiment of the present invention. [Figure 2] This is an enlarged view of the main part of Figure 1. [Figure 3] This is an explanatory diagram of the first step in the usage process, showing the container in the tilted position as shown in Figure 1. [Figure 4]It is an explanatory diagram of the second step of the usage operation showing the state where the head member of the container is rotated. [Figure 5] It is an explanatory diagram of the third step of the usage operation showing the state where the body part is squeezed.

Best Mode for Carrying Out the Invention

[0012] Figures 1 to 5 show a spray container according to an embodiment of the present invention. This spray container is formed by a container body 2, an inner stopper 10, a cap 20, and a head member 40. Each of these members can be formed of, for example, a synthetic resin material. This spray container can be used, for example, when storing a liquid containing a fragrance component for scenting alcoholic beverages.

[0013] As shown in FIG. 1, the container body 2 has a cylindrical body portion 4 continuous with the peripheral edge of the bottom portion 3, and a mouth-neck portion 8 is erected from the upper end of the body portion 4 via a shoulder portion 6. As shown in FIG. 5, the body portion 4 is formed into a squeezing body portion capable of elastically squeezing an intermediate portion 4b thereof. In this specification, the body portion 4 is divided and described into a lower portion 4a for storing a liquid in a upright state, an intermediate portion 4b for applying a squeezing force, and an upper portion 4c for arranging the lower end of a pipe cylinder portion 18 described later. An annular bulging portion 9 bulging outward is formed at the lower portion of the mouth-neck portion 8. Further, a first anti-detachment rib p1 (a pair of upper and lower ribs in the illustrated example) for locking to the inner stopper 10 side is provided around the upper portion of the mouth-neck portion 8.

[0014] As shown in FIG. 2, the inner stopper 10 integrally vertically provides a pipe cylinder portion 18 inserted into the mouth-neck portion 8 from the upper end side of a first mounting cylinder 12 fitted (plugged in the illustrated example) to the outer surface of the mouth-neck portion 8 via a first flange-shaped wall 14.

[0015] In the illustrated example, the first mounting cylinder 12 is formed by projecting a large-diameter lower cylinder portion 12c via a tapered intermediate cylinder portion 12b from a small-diameter upper cylinder portion 12a. On the inner surface of the upper cylindrical portion 12a, a pair of first receiving ribs q1 are provided which engage with the upper surface of the upper first retaining rib p1 and the lower surface of the lower first rib p1, respectively. On the outer surface of the upper cylindrical portion 12a, an external thread portion j that meshes with the internal thread portion k of a cap 20 described later is formed. Of course, these structures can be changed as appropriate. For example, instead of the external thread portion and the internal thread portion, retaining ribs and rib receivers may be formed. On the outer surface of the lower cylindrical portion 12c, locking protrusions 13 for locking to a receiving portion 25 of a cap 20 described later project, and these locking protrusions 13 and the receiving portion 25 form a rotation prevention means S between the middle plug 10 and the cap 20.

[0016] From the inner peripheral end of the first flange-shaped wall 14, the pipe cylindrical portion 18 hangs down, and from the lower surface of the first flange-shaped wall 14, a first seal cylinder 16 that closely adheres to the upper end portion of the inner surface of the mouth-neck portion 8 hangs down. Also, an appropriate number (at least two in the illustrated example) of first communication holes h1 are opened in the first flange-shaped wall 14.

[0017] In the illustrated example, the pipe cylindrical portion 18 hangs down to the upper portion 4c of the body portion 4 through the inside of the mouth-neck portion 8, and an air inlet i is opened at its lower end. Also, the lower portion of the pipe cylindrical portion 18 is formed into a tapered portion 19 that narrows downward. According to this structure, in the inverted state of the container body, it is difficult for the contents to enter the pipe cylindrical portion 18. As will be described in the liquid filling operation later, the liquid can be filled through the pipe cylindrical portion 18 with the middle plug 10 attached to the mouth-neck portion 8 in advance. The inner diameter of the pipe cylindrical portion 18 can be set to a size sufficient for appropriately performing the liquid filling operation.

[0018] The cap 20 is formed by erecting a shaft cylinder 28 that also serves as a ventilation cylinder from the upper end side of a second mounting cylinder 22 mounted (screwed in the illustrated example) on the outer surface of the first mounting cylinder 12, via a second flange-shaped wall 26. However, as will be described later, the cap 20 may be caulked onto the outer surface of the first mounting cylinder 12.

[0019] The inner surface of the second mounting cylinder 22 has a female threaded portion k that engages with the male threaded portion j. Furthermore, an expanding cylindrical portion 24 is suspended from the lower end of the second mounting cylinder 22 via an outward-facing flange 23, and a receiving portion 25 that abuts against the locking projection 13 is attached to the inner surface of this expanding cylindrical portion 24.

[0020] As shown in Figure 2, the second flange-like wall 26 is positioned to cover the upper surface of the first flange-like wall 14. An annular pressure-contact rib n is formed on the lower surface of the second flange-like wall 26, which is in pressure contact with the first flange-like wall 14. In the illustrated example, the shaft cylinder 28 is erected from the inner circumferential end of the second flange-shaped wall 26, and a circumferential partition wall 34 surrounding the shaft cylinder 28 is erected from the upper surface of the second flange-shaped wall 26. The shaft cylinder 28 is the part that serves as the axis of rotation for the head member 40. Its structure will be described later. Furthermore, the circumferential partition wall 34 is a part that defines a space (liquid cabinet C) in which liquid is contained between it and the shaft cylinder 28. The outer surface of the circumferential partition wall 34 is provided with a second retaining rib p2 for engaging with the second rib receiver q2 of the head member 40, which will be described later. Furthermore, a pipe sealing cylinder (second sealing cylinder 27) is suspended from the lower surface of the second flange-shaped wall 26, which is fitted liquid-tightly to the upper end of the inner surface of the pipe cylinder portion 18. Furthermore, as shown in Figure 2, a second communication hole h2 is provided in the second flange-shaped wall 26, which connects the first communication hole h1 to the liquid cabinet C. This second communication hole h2 is positioned between the second seal cylinder 27 and the circumferential partition wall 34 when viewed from above.

[0021] The shaft cylinder 28 serves as the axis of rotation for the head member 40 and also functions as a ventilation cylinder. In the illustrated example, a small inner diameter portion 29 is formed on the upper inner surface of the shaft cylinder 28, and an air intake port 30 is formed on its upper end. Furthermore, a first fluid channel 32, which serves as a flow path for the liquid contents, is vertically provided on the outer surface of the upper half of the shaft 28 in the illustrated example.

[0022] The head member 40 is a top-mounted cylindrical member formed by extending an outer peripheral wall 44 vertically from the circumferential end of the top plate 42. This head member 40 is attached to the cap 20 by fitting a bearing cylinder 46, which extends vertically from the top plate 42, to the outer surface of the shaft cylinder 28 in a liquid-tight and rotatable manner. The top plate 42 has a spray nozzle о that is located inside the bearing cylinder 46 and communicates with the air intake port 30. The space enclosed by the top plate portion near the spray nozzle о, the upper end surface of the shaft cylinder 28, and the bearing cylinder 46 is formed as a gas-liquid mixing section m. This gas-liquid mixing section m has the role of mixing the liquid supplied through the first liquid passage groove 32 and the second liquid passage groove 50 (described later) with the air supplied through the air intake port 30 of the shaft cylinder 28, atomizing it, and ejecting it from the spray nozzle о. In the illustrated example, the gas-liquid mixing section m is not provided with a spin mechanism, but a spin mechanism may be provided. A second fluid passage groove 50 is vertically provided on the inner surface of the lower half of the bearing cylinder 46 in the illustrated example. An inner circumferential wall 54 that fits onto the outer surface of the circumferential partition wall 34 and a third sealing cylinder (partition sealing cylinder) 52 that fits liquid-tightly onto the upper inner surface of the circumferential partition wall 34 are respectively suspended from the lower surface of the top plate 42. As shown in Figure 2, a second rib receiver q2, which is a receiving groove for fitting the second retaining rib p2, is provided around the inner surface of the inner circumferential wall 54. Furthermore, the inner circumferential wall 54, the outer circumferential wall 44, and the top plate 42 are connected to form a radial reinforcing wall portion 56 when viewed from above.

[0023] In the above configuration, when assembling the liquid container of the present invention, the inner stopper 10 is inserted into the neck portion 8 of the container body 2, and then the cap 20 is screwed onto the inner stopper 10 with the bearing cylinder 46 of the head member 40 fitted onto the shaft cylinder 28 of the cap 20. When filling this container with liquid, the contents can be filled through the pipe section 18 with the inner stopper 10 already installed between the process of inserting the inner stopper and the process of screwing on the cap. In addition, the cap 20 and the inner stopper 10 can be fitted together by pressing rather than screwing. If a pressing method is used, it is preferable to provide retaining ribs on both the cap 20 and the inner stopper 10. Since the pipe section 18 is integrated as part of the stopper 10, there is no need to attach the pipe to the stopper, and assembly is easy.

[0024] When using the liquid container of the present invention, liquid is placed in the lower portion 4a of the body 4 of the container body 2, as shown in Figure 1. The amount of liquid is set so that, when the container is inverted as shown in Figure 4, the liquid level does not exceed the height of the inlet i of the pipe cylinder portion 18. Then, when the container is tilted so that the inlet i of the pipe section 18 is facing upwards (see Figure 3), the liquid inside the container body 2 flows into the gap V between the neck 8 and the pipe section 18. Next, by rotating the head member 40 while the container is inverted (see Figure 4), the first liquid passage groove 32 and the second liquid passage groove 50 are made continuous. As a result, the void V communicates with the liquid cabinet C, and preparations for spraying are complete. In this state, as shown in Figure 5, when the middle section 4b of the body 4 is compressed, the liquid supplied through the first and second communication holes h1 and h2 and the first and second liquid passage grooves 32 and 50, and the air supplied through the pipe section 18 and the shaft 28, are mixed in the gas-liquid mixing section m and ejected as mist from the spray nozzle o. After spraying is finished, when the compression of the body 4 is released, the elastic recovery of the body 4 creates negative pressure inside the container 2, and outside air flows into the container 2 through the spray port o, thereby eliminating the negative pressure inside the container 2. Next, the container is returned to an upright position, and the container body 2 is rotated to block communication between the first communication hole h1 and the second communication hole h2. In the aforementioned series of processes, the head member 40 can be rotated to enable mist ejection, and unlike conventional technology, there is no need to pay attention to the orientation of the lid, making it easy to use.
