DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to self-restoring the original shape by squeezing a container with fingers to extrude fluid contents such as shampoos and hair dyes. The present invention relates to an extrusion container.

[0002]

2. Description of the Related Art Conventionally, contents are extruded by squeezing and deforming the body of a synthetic resin bottle having a spout, and when the squeezing is stopped, the outside air is sucked in from the spout of the spout and the bottle is self-restored. 2. Description of the Related Art A cylindrical extruded container with a bottom, which is a so-called squeeze container that can stand up and stand by itself, is well known.

[0003] Although this known extrusion container self-recovers by sucking outside air from the spout after extruding the contents, the spout always remains open during use.
If the container is accidentally knocked down during use, the contents may be spilled. In the case of shampoos, hair dyes, facial cleansers, and other items used in the bathroom, hot water flows in from the spout during showering, and if stored in a high-humidity location, steam will become water droplets. There was a case where the contents were deteriorated by flowing. If the spout is closed each time in order to avoid such inconvenience, particularly in the case of shampoo or the like, it must be closed with hot water, which is extremely troublesome and inconvenient for consumers.

Therefore, for example, Japanese Utility Model Laid-Open No. 1-103542
As in the container disclosed in Japanese Patent Application Publication, a check valve is provided in the plug, the container is squeezed, the internal pressure is increased, the check valve is opened with the contents, and the container is squeezed to stop the pressing. An extrusion container has been proposed in which the check valve is closed to prevent the contents from spilling when the pressure in the container becomes negative due to the self-restoration of the container.

However, in the case of a container having the above-described check valve, when the squeezing is stopped, the check valve closes before the container is completely self-restored by sucking air. Therefore,
It is difficult to use or store it upright, making it a practically inconvenient container.

The extrusion container shown in FIG. 5 disclosed in Japanese Utility Model Laid-Open Publication No. 3-1088651 has a first check valve 51 which is opened only when the container body 50 is squeezed and the internal pressure rises. And a second check valve 52 that opens only when the internal pressure of the container body 50 is reduced to separately discharge the contents and sucks the outside air.
1 and 52 are provided to solve the problems of shutting off outside air and self-recovery. That is, when the squeezing is stopped, the second check valve 52 opens, sucks the outside air, and restores the container body 50 by itself, the first check valve 51 in the plug 53 closes, and the container body 50 falls down. Also, the contents are prevented from leaking.

[0007]

However, since the conventional extrusion container has a structure in which the spout 54 of the spout 53 is always open, hot water flows from the spout 54 when used in a bathroom or the like. They stayed inside the plug 53 and tended to be unsanitary.

The present invention has been made in view of the above-mentioned problems. When the pressing of the container is stopped, the container self-returns by sucking outside air, and the contents do not flow out even if the container is tilted during use. It is an object of the present invention to provide an extrusion container in which hot water does not flow into the container even when the lid is open.

[0009]

The present invention relates to an extruded container comprising a self-restoring cylindrical container body having a bottom with a erected neck, and a spout fitted to the cervix. Along with providing a flow hole penetrating the top and bottom surfaces of the top wall of the plug,
A flexible film having air permeability and water resistance having uniform fine holes on the top surface of the top wall is closely overlapped and partially adhered, and a non-adhered portion of the film communicates with the flow hole and With the configuration in which an automatic opening / closing duct having a spout is formed at one peripheral edge of the top wall upper surface, the film prevents water and water intrusion and leakage of the contents even when the lid is open, and the container body has The contents are opened and extruded by squeezing, and the ducts are self-closed when squeezing is stopped, and the container body is self-restored by sucking outside air through the film.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

FIGS. 1 to 4 show an embodiment of an extrusion container according to the present invention. The container body 1 has a self-restoring cylindrical shape having a bottom and an upright neck 2. And a plug 10 fitted to the plug.

The container body 1 is a single layer made of a general-purpose synthetic resin material such as polyethylene, polypropylene, vinyl chloride, pet, or the like and has a multilayer elastic restoring force. The male screw 3 is screwed.

The mouth plug 10 has a cylindrical plug body 15 having a top wall 11 provided with flow holes 12 penetrating in the upper and lower surfaces, and having a female screw 13 screwed into the male screw 3 on an inner peripheral surface thereof. Body 1
Opening / closing lid 16 which covers the top wall 11 by being superimposed on the upper surface of
Are connected integrally so as to be elastically inverted by a well-known three-point hinge 17 at each rear end, and have a well-known shape called a so-called snap cap or a mirror cap.

At the front end of the plug body 15 opposite to the three-point hinge 17, a beak 18 having a flat upper surface flush with the upper surface of the top wall 11 is projected from the outer peripheral wall. On the upper surface, a film 20 is covered so as to cover the distribution port 12 and extend to the tip of the upper surface of the beak 18. The film 20 is adhered to the upper surface of the top wall 11 in a region indicated by cross-hatching in FIG. 1 by a well-known heat welding means or a thermocompression bonding means using a hot melt agent.

The film 20 is a flexible film having uniform fine pores and excellent in air permeability and water resistance and produced by a dry method using a combination of an olefin resin and a fine filler (for example, Mitsui Toatsu Chemical, a commercial product). Name: Aspo Earl)
The unbonded portion of the film 20 including the outflow holes 12 is an automatically openable / closable duct 21 that is in airtight contact with the upper surface of the top wall 11 and communicates with the outflow holes 12. The top end of the upper surface of the beak 18 of the top wall 11 is a spout 22 for the duct 21.

When storing the extrusion container of the present embodiment constructed as described above, as shown in FIG. From the upper surface of the film 20 to the flow holes 12
The outflow hole 12 is closed by pressing the periphery.

The spout 10 in the present embodiment is commonly called a snap cap or a mirror cap in which a spigot body 15 and an opening / closing lid 16 are integrally connected by a three-point hinge 17. The plug 10 is not limited to this form, and it goes without saying that, for example, a well-known type in which a male screw is provided on the outer peripheral surface of the plug main body 15 and a screw cap is fitted.

When extruding the fluid contents N from the extrusion container, the body 4 of the container body 1 is squeezed from outside by fingers after the opening and closing cover 16 is opened. Then, as shown in FIG.
The pressurized contents N pushes and opens the closed duct 21 from the outlet hole 12 by itself, and is pressed into the duct 21.

Since the non-adhered portion of the film 20 adhered to the upper surface of the plug body 15 is in close contact with the duct 21, when the pressure of the contents N rises above the elastic tension of the film 20, The portion of the duct 21 that is 20 bends and expands by receiving the entry pressure of the content N, and the content N is discharged from the spout 22 while automatically pushing and opening the closed duct 21.

Next, when the pressing of the container body 1 is stopped and the pressure of the contents N decreases, as shown in FIG.
Is automatically controlled by the elastic tension of the film 20 itself.
5 and close to the upper surface of the airtight member 5 to close the air hole 12 and restore the closed state. Further, since the film 20 has air permeability and water resistance, the container body 1 restores the original shape by sucking the outside air through the film 12 through the film 20 by the negative pressure in the container due to the self-recovery. . And even if it is continued to be used in a bathroom or the like, there is no fear that hot water enters the container body 1.

As described above, the container body 1 is self-returning and can be always placed upright, as in the conventional squeeze container, so that it is convenient for use and storage, and also the conventional squeeze container. Unlike this, even if it is accidentally knocked down during use, the contents N do not leak, no external hot water enters, and no hot water or dust stays. Therefore,
It can be used in bathrooms without worrying about intrusion of hot water without closing the lid.

[0022]

The present invention is embodied in the form described above and has the following effects.

An air-permeable and water-resistant flexible film having uniform fine pores is closely laminated on the upper surface of the top wall of the plug and partially adhered, and the non-adhered portion of this film is communicated with the flow hole. In addition, since the duct is an auto-opening / closing duct with a spout at one peripheral edge of the top wall, the contents can be pushed out through the duct by squeezing the container body, and the duct closes automatically by stopping the squeezing. Then, external air is sucked into the container main body from the surface of the film by the negative pressure accompanying the self-restoration of the container main body, and the container main body becomes in a state of being able to stand alone. Therefore, it is easy to store and can be used simply like a conventional squeeze container.

In addition, since the outflow holes are always covered with a water-resistant film even when the lid is opened, there is no fear of spilling the contents even if it is accidentally knocked down, and the intrusion of hot water or water droplets from the outside is always blocked. It is possible to use it while taking a shower, and even if it is stored in a humid place with the lid open, water will enter the container and the contents will deteriorate, or water will collect and unsanitary This reduces the burden of attention during use and is convenient.

Further, since it can be easily manufactured only by partially bonding a flexible film having air permeability and water resistance to the upper surface of the plug, it can be provided at a low cost with a small number of parts.
