Description

The present invention relates to a spray container that sprays liquid contents onto the hand that operates it.

From the viewpoint of public health, it is considered effective to disinfect hands and fingers with an alcohol disinfectant or the like. As a means for spraying the contents of such an alcohol disinfectant or the like onto hands and fingers, a pump-type spray container has been developed that includes a container body that holds the contents, a pipe that draws up the contents inside the container body, a pump mechanism attached to the upper end of the pipe, and a nozzle head that is attached to the upper end of the pump mechanism and has a nozzle that sprays the contents (for example, Patent Document 1).

The pump mechanism includes, for example, a cylinder and a piston, and a certain amount of the liquid content sucked up from the pipe is stored in the cylinder. This type of pump mechanism is configured so that when the user presses down on the nozzle head (when operating), the piston descends inside the cylinder, and while it is descending, a valve around the piston opens. This causes the liquid content in the cylinder to be pushed upward through the valve around the piston and sprayed out of the nozzle. When the user releases the nozzle head, the spring inside the cylinder moves the piston upward (when returning), the valve around the piston closes, and the check valve located at the bottom of the cylinder opens, so that the liquid content in the container is sucked up through the pipe and the cylinder is filled with a certain amount of liquid again.

However, the pump-type spray container in Patent Document 1 requires a relatively expensive pump mechanism, which makes it difficult to reduce manufacturing costs.

In addition, the pump-type spray container in Patent Document 1 requires one hand to press down the nozzle head while the other hand must receive the liquid contents sprayed out of the nozzle, making it difficult to operate with only one hand, and there is also the problem that a user carrying luggage cannot operate it alone unless they first place their luggage on the ground or the like to free both hands.

The present invention aims to solve the problems of the conventional technology described above by creating a simple, inexpensively manufactured spray container that can spray the liquid contents onto the hand that handles it.

Among the means for solving the above problems, the first main means of the present invention is:
A spray container comprising: a container body for storing liquid contents; a container-side lid attached to an opening of the container body; a tray having an upper surface with a spray hole for spraying the liquid contents; a pipe for leading the liquid contents in the container body to the tray; and an elastically deformable part that is elastically deformable and changes the internal pressure of the container body;
When the tray is pressed down, the elastic deformation portion is compressed and deformed, pressurizing the inside of the container body, so that the liquid content is pushed up the pipe and ejected from the ejection hole provided in the tray .
A connecting tube that communicates with the ejection hole and to which a pipe is connected is suspended from the receiving tray, and an air hole that communicates with the ejection hole and the inside of the container body is formed between the inner surface of the connecting tube and the outer surface of the pipe .
The first main aspect of the present invention does not require a relatively expensive pump mechanism, and can have a simple structure, and can eject the liquid content by operation with only one hand.
It is also possible to achieve shower-like ejection of the liquid content.

The second main aspect of the present invention is to
A spray container comprising a container body for containing a liquid content, a container-side lid attached to the mouth of the container body, a tray having an ejection hole on the upper surface for ejecting the liquid content, a pipe for leading the liquid content in the container body to the tray, and an elastically deformable part that is elastically deformable and changes the internal pressure of the container body,
When the tray is pressed down, the elastic deformation portion is compressed and deformed, and pressure is applied inside the container body, so that the liquid content is pushed up inside the pipe and ejected from the ejection hole provided in the tray,
The container side lid has a lid side through hole and a connecting tube that communicates with the lid side through hole and is connected to a pipe, and the connecting tube has an air hole that communicates with the lid side through hole and the inside of the container body.
The second main means also makes it possible to achieve shower-like ejection of the content liquid.

Another aspect of the present invention is to add to the above-mentioned aspect that a guide passage is formed in the portion where the receiving tray and the top wall of the container side lid body face each other, connecting the lid side through hole and the ejection hole.
With the above-mentioned means, the ejection holes can be provided at positions radially outward from the center of the tray, so that the liquid content can be ejected over a wider range.

Another means of the present invention is any of the above means, in which a dish lid covering the upper surface of the tray is connected via a hinge provided at one end of the tray, and a plug member for blocking the nozzle hole when the lid is closed is provided on the underside of the dish lid opposite the nozzle hole.
With the above-mentioned means, leakage of liquid from the nozzle hole can be effectively prevented.

The present invention can have a simple configuration without using a relatively expensive pump mechanism, so that the manufacturing cost of the ejection container can be reduced.
Furthermore, the liquid contents can be ejected by operating with only one hand, without using both hands.

FIG. In the spouting container of FIG. 2, (a) is a plan view showing one embodiment of a receiving tray, and (b) is a cross-sectional view showing the tray lid in an open state.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
First, a first embodiment of the jet container will be described.
As shown in FIG. 1 and FIG. 2, the ejection container 1A of the first embodiment is composed of a container body 10A, a container side lid 20A, a connecting member 30, a bellows member 40, a push-down member 50A, and a pipe 60, all of which are formed using a synthetic resin material.

The container body 10A is formed by blow molding a synthetic resin material such as polyethylene (PE), and is a bottomed, tubular member in which a cylindrical mouth 14 is erected via a shoulder 13 formed by forming the upper end of a tubular body 12 connected to the bottom 11 into a reduced diameter shape. A male thread 15 is engraved on the outer periphery of the mouth 14.

The container side lid 20A is a topped tubular member with a cylindrical peripheral wall 22 that is integrally attached and hangs down from the outer edge of the top wall 21. An opening 23 is formed in the top wall 21, and a female threaded portion 24 that screws into the male threaded portion 15 of the mouth portion 14 is formed on the inner circumferential surface of the peripheral wall 22. In addition, a restricting portion 22a that is formed in a ring shape and extends radially outward is formed at the lower end of the peripheral wall 22. The container side lid 20A is assembled to the mouth portion 14 by screwing the female threaded portion 24 into the male threaded portion 15.

The connecting member 30 has a flange 32 in the shape of a flat ring with an opening 31 in the center, and a holding portion 33 made of a double cylinder is formed on the upper surface of the flange 32. When the container side lid 20A is attached to the mouth 14, the connecting member 30 is assembled in a state in which the flange 32 is sandwiched between the tip of the mouth 14 and the top wall 21.

The bellows member 40 is configured to have a bellows-shaped elastic deformation portion 41 that is elastically deformable in the vertical direction, a cylindrical lower connection portion 42 connected to the lower end of the elastic deformation portion 41, and a cylindrical upper connection portion 43 connected to the upper end and having a male thread portion 44 formed on its outer periphery. The bellows member 40 is assembled in a state in which the lower connection portion 42 is inserted into the holding portion 33 of the connecting member 30 to connect them, and the male thread portion 44 of the upper connection portion 43 is screwed into the female thread portion 54a formed on the dish side holding portion 54 of the receiving dish 51 described later.

The pressing member 50A is formed with a tray 51 formed with a diameter expanding upward, a hollow ejection projection 52 protruding upward from the center of the tray 51 and having a plurality of ejection holes 52a (two in this embodiment) at the tip, a connecting tube 53 provided at the center of the underside of the tray 51 and to which the upper end of the pipe 60 is connected, a tray side holding part 54 formed of a double cylinder provided on the underside of the tray 51 and having a female threaded part 54a that screws into the male threaded part 44 of the upper connecting part 43 of the bellows member 40 and connected to the upper connecting part 43, a cylindrical outer tube part 55 suspended from the underside of the tray 51 at a position radially outside the upper connecting part 43 and movable up and down along the peripheral wall 22 of the container side lid 20A, and a tray lid 57 provided rotatably via a hinge 56 formed with a thin wall on the outer edge of the tray 51.

The push-down member 50A is assembled in a state in which it is elastically provided to the container body 10A via the elastically deformable elastic deformation part 41 by connecting the upper connection part 43 of the bellows member 40 to the dish side holding part 54. The inside of the ejection protrusion 52 provided on the upper surface side of the tray 51 communicates with the connecting tube 53 provided on the lower surface side of the tray 51. The connecting tube 53 is also provided with an air hole 53a that communicates the ejection hole 52a with the inside of the container body 10B. Furthermore, as shown in FIG. 2(a), a plurality of dish side through holes 51a are formed on the tray 51 and at a position radially outward from the ejection protrusion 52.

A cap 57a protrudes from the underside of the dish lid 57, and functions as a closure member by fitting the ejection projection 52 when the lid is closed. An engagement portion 57b and a gripping piece 57c are formed at the outer edge of the tray 51 on the opposite side from the hinge 56. The engagement portion 57b is configured to be able to engage with an engaged portion 51b provided on the outer edge of the tray 51.

The pipe 60 is formed of a flexible, elongated cylindrical sleeve, the upper end of which is connected to the connecting tube 53, and the lower end of which is slightly curved and reaches the bottom 11 of the container body 10A. As described below, the liquid content rises from the lower end to the upper end of the pipe 60, is guided to the ejection protrusion 52 via the connecting tube 53, and can be ejected to the outside from the ejection hole 52a formed at the tip of the ejection protrusion 52.

Next, the operation of the jetting container of the first embodiment having the above-mentioned configuration will be described.
To spray the liquid contents from the spray container 1A, the user pinches and lifts the gripping piece 57c to disengage the engaging portion 57b from the engaged portion 51b, and then rotates the dish lid body 57 counterclockwise as shown in the figure to set it to the open lid state.

Next, the press member 50A is pressed downward while one hand is placed against the upper edge 51A of the tray 51. Then, as shown in FIG. 2(b), the elastic deformation portion 41 is compressed and deformed, pressurizing the inside of the container body 10A, and the liquid content is pushed by the internal pressure and its water level drops, so that the liquid content is pushed up from the lower end of the pipe 60 toward the upper end, reaches the connecting tube 53, and tries to be discharged to the outside from the nozzle 52a of the ejection protrusion 52. At the same time, the compressed air in the container body 10A reaches the connecting tube 53 through the air vent 53a and is discharged to the outside through the nozzle 52a of the ejection protrusion 52, so that the liquid content can be forcefully ejected from the nozzle hole 52a in a shower-like manner. Therefore, the liquid content can be ejected over a relatively wide area of the operating hand without using both hands.

The pushing member 50A can be pushed down to a position where the lower end of the outer cylinder portion 55 abuts against a restricting portion 22a formed on the container side lid 20A.
In addition, the tray 51 can receive the liquid contents leaking out from the ejection holes 52a. Furthermore, since the tray 51 has a plurality of tray-side through holes 51a, the liquid contents can be prevented from remaining on the tray 51.

When the hand that pressed down is removed from the upper edge 51A of the tray 51, the elastic deformation portion 41 returns upward, reducing the pressure inside the container body 10A, causing the pressing member 50A to return to its initial state before compression deformation. At this time, external air is drawn into the container body 10A through the outlet 52a, the inside of the connecting tube 53, and the air vent 53a, and the internal pressure of the container body 10A returns to its initial state before compression, so that the ejection from the outlet 52a can be stopped.

The user can then rotate the dish lid 57 in the clockwise direction while pinching the tab 57c, engaging the engaging portion 57b with the engaged portion 51b to return the dish lid to the closed state (initial state) shown in FIG. 1. In this closed state, the cap 57a provided on the underside of the dish lid 57 fits over the ejection projection 52 and plugs the ejection hole 52a, preventing liquid from leaking from the ejection hole 52a.

Next, a second embodiment of the jetting container will be described.
The ejection container 1B shown as the second embodiment in Figures 3 and 4 is composed of a container body 10B, a container side lid 20B, a push-down member 50B, and a pipe 60 having a configuration similar to that of the first embodiment, all of which are formed using synthetic resin material.

The container body 10B is formed by blow molding a synthetic resin material such as polyethylene (PE), and is a bottomed, tubular member in which an elastically deformable bellows-like elastic deformation portion 16 is formed integrally with the upper portion of the body portion 12 connected to the bottom portion 11, and a cylindrical mouth portion 14 is erected on the upper portion of this elastic deformation portion 16. A male screw portion 15 is engraved on the outer circumferential surface of the mouth portion 14.

The container side lid 20B is a topped tube-shaped member with a cylindrical peripheral wall 22 that is integrally suspended from the outer edge of the top wall 21. The inner peripheral surface of the peripheral wall 22 is formed with a female thread 24 that screws into the male thread 15 of the mouth 14, and the outer peripheral surface of the peripheral wall 22 is formed with an engagement protrusion 26 that engages with the inner tube 58 that constitutes the pressing member 50B described later. In addition, a lid side through hole 21a is formed in the center of the top wall 21, and a connecting tube 25 that communicates with the lid side through hole 21a is suspended from the underside of the top wall 21. In addition, a vent hole 25a that communicates between the lid side through hole 21a and the inside of the container body 10B is provided in the connecting tube 25. In addition, on the upper surface of the top wall 21 and at a position radially outward from the central lid side through hole 21a, engagement holes 21b are arranged in an annular or circumferentially intermittent manner.

The pushing member 50B is formed with a tray 51 formed to expand in the upward direction, an outer tube portion 55 suspended from the outer peripheral end of the tray 51 and capable of moving up and down along the elastic deformation portion 16 of the container body 10B, an inner tube portion 58 suspended from the underside of the tray 51, and a tray lid 57 rotatably mounted via a hinge 56 formed with a thin wall on the outer edge of the tray 51.

The tray 51 is provided on its underside with guide passages 51c consisting of a plurality of (three in this embodiment) grooves formed radially from the center, and an engagement piece 51e protruding from the underside of the tray 51, and on its upper side with a jet hole 51d leading to the tip of the guide passage 51c. The base ends of the guide passages 51c are gathered at the center of the tray 51, and in the assembled state where the engagement piece 51e is engaged with the engagement hole 21b of the container-side lid 20B, the base ends of the guide passages 51c are set in communication with the lid-side through-hole 21a of the container-side lid 20B.
As shown in FIG. 4A, a plurality of dish-side through holes 51a are formed on the receiving dish 51 at positions radially outward of the lower engaging pieces 51e.

An engaging recess 58a is formed on the inner peripheral surface of an inner cylinder portion 58 constituting the push-down member 50B, and engages with the engaging protrusion 26 formed on the outer peripheral surface of the peripheral wall 22 of the container side lid 20B.
Furthermore, a plurality of (three in this embodiment) protrusions 57d are provided on the underside of the dish lid 57 at positions opposite to the respective ejection holes 51d, and function as plugging members when the lid is closed.

Next, the operation of the jetting container of the second embodiment having the above-mentioned configuration will be described.
To eject the liquid contents from the ejection container 1B, as in the first embodiment, the user pinches and lifts the gripping piece 57c to release the engagement between the engaging portion 57b and the engaged portion 51b, and then rotates the dish lid body 57 counterclockwise as shown in the figure to set it to the open state.

Next, the press member 50B is pressed downward while the hand is in contact with the upper edge 51A of the tray 51. Then, as shown in FIG. 4B, the elastic deformation portion 16 is compressed and deformed, pressurizing the inside of the container body 10B, and the liquid content is pushed by the internal pressure and the water level drops, so that the liquid content is pushed up from the lower end of the pipe 60 toward the upper end side and reaches the connecting tube 25, where it branches out from the lid-side through hole 21a to each guide passage 51c, advances radially outward in each guide passage 51c, and tries to be discharged upward from the ejection hole 51d provided at the tip of each guide passage 51c. At the same time, the compressed air in the container body 10B reaches the lid-side through hole 21a through the inside of the connecting tube 25 from the air vent 25a, and is further discharged upward from each ejection hole 51d following the same route as the liquid content, so that the liquid content can be vigorously ejected from each ejection hole 51d in a shower-like manner. Therefore, the liquid content can be sprayed over a relatively wide area of the hand that operates the device, without using both hands.
In the second embodiment, the tray 51 can also receive the liquid contents leaking out from each of the ejection holes 51d. In addition, since the tray 51 has a plurality of tray-side through holes 51a, the liquid contents can be prevented from remaining on the tray 51.

Furthermore, when the pressing hand is removed from the upper edge 51A of the receiving tray 51, the elastic deformation portion 16 returns to its upward position, reducing the pressure inside the container body 10B, and the pressing member 50B returns to its initial state before compression deformation. At the same time, external air is drawn into the container body 10B through each of the ejection holes 51d, the guide passage 51c, the lid side through hole 21a and the air vent 25a, and the internal pressure of the container body 10B returns to its initial state before pressurization, thereby stopping the ejection from the ejection hole 51d.
Then, the user pinches the tab 57c and rotates the dish lid 57 in the clockwise direction to engage the engaging portion 57b with the engaged portion 51b, thereby returning the dish lid 57 to the closed state (initial state) shown in Fig. 3. In this closed state, the projections 57d on the underside of the dish lid 57 plug the nozzle holes 51d, thereby preventing liquid from leaking from the nozzle holes 51d.

Although the configuration and effects of the present invention have been described above based on the embodiments, the present invention is not limited to the above embodiments.
For example, in the above first embodiment, the container side lid 20A, the connecting member 30 and the bellows member 40 are each described as separate members, but the present invention is not limited to such a first embodiment, and may be configured such that the container side lid 20A and the connecting member 30 are formed integrally, or the connecting member 30 and the bellows member 40 are formed integrally, or the container side lid 20A, the connecting member 30 and the bellows member 40 are formed integrally.

In the second embodiment, the guide passage 51c is formed on the underside of the tray 51, but it can also be formed on the upper surface of the top wall 21 of the container-side lid 20B.

In addition, in the above first and second embodiments, a bellows-shaped bellows member 40 that is elastically deformable in the vertical direction is shown and described, but the present invention is not limited to this, and a bellows member 40 that is elastically deformable in the radial direction may also be used.

The present invention can expand the range of applications in the field of spray containers that spray liquid contents such as alcohol disinfectant.
