Description

[Detailed description of the device]

[0001]

[Industrial applications]

 It is a double-structured container consisting of an outer container and an inner container for fluid substances and cream-like substances. Specifically, the inner container of the double-structured container can be detached from and put in and out of the outer container. The container is characterized in that it is replaced and the outer container is repeatedly used, and the inner container is a semi-hard surface type composite tube container.

[0002]

[Prior art]

 The conventional double-structured container is equipped with a tube container as an inner container, is provided with a discharge port for the contents and an air port separately, and also uses a pump function or an air pump to inflate a balloon inside the container. Then, the contents are extruded (for example, utility model application publications 60-60840, 60-188149, 61-129739).

In a conventional container with a partition film, a partition film is fixed in the container, and a discharge port for the contents and an air port are separately provided for exclusive use, and the contents are provided by a pump function. Extrude (for example, the one before the divisional application of the present case (Head 1-121698)).

Conventional tube containers other than the double-structured container or the container with a partition membrane are deformable containers whose container walls are made of a flexible material (for example, a toothpaste tube container) and are pressed with a finger. Push out the contents by doing the same.

[0005]

[Problems to be solved by the device]

 The conventional double-structured container and the container with a partition membrane cannot repeatedly use the outer container by the method of replacing the inner container, and the outer container also becomes disposable, which reduces costs, resources, environment, etc. I cannot avoid the slander that points are not taken into consideration.

In addition, in the case of tube containers other than the conventional double-structured container or the container with a partition membrane, the inconvenience of the operation of discharging the contents (for example, the discharge from the toothpaste tube container with a small remaining amount is There are two drawbacks: uniform pressure on the entire surface and pushing it out, and squeezing the remaining amount to the discharge port.)

[0007]

[Means for Solving the Problems]

 The inner container is a double-structured container that is a half-faced rigid composite tube container in which the flexible membrane tube is only half the surface of the inner container, and a content discharge pump is provided to , Allow sufficient and forcible discharge with simple operation.

A container having a structure capable of opening and sealing an outer container, for example, a container having a structure in which the opening of a pudding-type opening container is closed with a screw lid or the like, and the body of the container is defined as an opening, and the opening is screwed. The container shall be constructed so that it can be connected to and removed from the outer container by means of a fastener such as a fastener, so that the inner container can be detached from and put in and out of the outer container so that the inner container can be exchanged for repeated use.

[0009]

[Action]

 Since the inner container can be detached from and put in and out of the outer container, when the contents of the inner container become empty, the outer container can be reused by replacing it with a new inner container. Since the contents can be discharged by the discharge pump, the contents can be sufficiently discharged by forcibly and with a simple discharging operation. Also, during the period of use after opening and opening, as in conventional tube containers, air does not enter the container, so the contents are not exposed to air, and the deterioration and decay of the contents is suppressed. , Can be prevented.

The air pump injects (= pressurizes) air into the air chamber from the air port, or presses the outer container while keeping the air in the air chamber, thereby pressing the content chamber to press the contents. Push out. The liquid pump sucks up or pushes up the content itself to make it flow out, or directly pushes out the content itself.

The content guide pipe guides the movement of the content from the content chamber to the content discharge port of the inner container or the content discharge nozzle of the outer container, or discharges the content from the content discharge nozzle of the outer container. Lead.

[0012] The contents reverse prevention device prevents the contents from returning to the contents chamber and enables the contents to be discharged in response to the discharging operation. In addition, the equipment to prevent the contents from reversing prevents air from flowing into the contents chamber from the contents discharge nozzle of the outer container, etc., and ensures the air blocking function for the contents in the contents chamber.

The bottom wall of the outer container is provided with a connection hole (9) such as a nozzle for discharging the contents of the outer container at the center thereof, which is inserted into this to connect the nozzle for discharging the contents of the row container (4). The nozzle for discharging the contents of the outer container is fixed on the side wall of the hard container material portion of the outer container and reaches a height exceeding the top of the container. At the center of the bottom wall of the inner container, a projecting inner container contents discharge port (3) is provided, and this inner container contents discharge port is connected to the connection hole (9) on the bottom wall of the outer container. ), So that the contents outlet of the inner container is connected to the contents discharge nozzle of the outer container. An air port (5) is provided on the ceiling wall of the outer container on the side opposite to the position of the outer container contents discharge nozzle. The container of this embodiment is provided with a handle (10) fixed to the side wall of the outer container, which is made of the material of the hard container on the side facing the outer container contents discharge nozzle.

2 Container of FIG. 2 In FIG. 2, the outer container (1) is an open container having a cylindrical main body (a container having a large open mouth such as a wide-mouthed bottle or a pudding container. In the container, a hard board-shaped lid is placed in the opening, and this is tightened to the outer container body with a ring-shaped screw to seal the inner container (2) to the outer container. It is a semi-hard type composite tube container that is almost the same shape and size as the contents storage space, with one half on the left and right sides made of a flexible membrane and the other half made of a hard material. The lid of the opening is provided with a connection hole (9) such as an outer container contents discharge nozzle, into which the outer container contents discharge nozzle is inserted and connected. In addition, the inner container contents discharge port (3) is provided in the upper part on the side made of a hard material of the inner container, and this inner container contents discharge port is the outer container of the disc-shaped lid of the outer container. It is inserted into the connection hole (9) such as the contents discharge nozzle and is connected to the outer container contents discharge nozzle (4). The outer container content discharge nozzle is provided with a content backflow prevention valve = contents backflow prevention device (7) that operates in response to the content backflow. An air port (5) is provided above the side wall of the outer container on the side opposite to the outer container contents discharge nozzle, and the air port is emptied from the air chamber when the outer container is pressed. An air backflow check valve = air pump (6) is installed to prevent air from flowing out.

[0014]

Effect of the Invention 1. The container of FIG. 1 has the following effects. When discharging the contents from this container, the container is tilted to be naturally discharged. (In addition, when it is necessary to forcibly discharge the contents from this container (when adjusting the catching of the partition membrane, when squeezing the remaining discharge amount, etc.), close the air port (5) with a finger or the like. Therefore, the wall of the restored material part of the outer container is pressed and discharged.) Air corresponding to the volume of the discharged content enters the air chamber (= in the outer container) through the air port. The volume of the contents chamber (= inner container) is reduced by denting the tube portion by the amount of discharged contents. When the contents chamber (2) is full, the tube part of the inner container is in contact with the wall of the outer container, but as the contents are discharged, the tube part of the inner container is dented and the contents are When it is completely discharged, the tube portion is in perfect contact with the hard material portion of the contents chamber, and the space in the contents chamber becomes zero. Since the contents of the outer container contents discharge nozzle (4), at least the part lower than the bottom wall of the container, are always filled with air, air flows into the contents chamber from the outer container contents discharge nozzle. The contents in the contents chamber can be used without being exposed to the air even after the cap is opened, and the alteration of the contents is prevented. When the contents of the inner container are exhausted, the outer container can be reused by opening the connecting part (8) of the outer container and replacing the empty inner container with a new inner container. .

2 The container of FIG. 2 has the following effects. To discharge the contents from this container, press the wall of the outer container (= resilient container) (1) while keeping the air in the air chamber (= outer container), and press the wall of the air chamber (= Inner container) The tube portion of (2) is depressed to allow the contents in the contents chamber to flow and be discharged from the outer container contents discharge nozzle (4). When the pressure on the outer container is stopped and the discharge is stopped, the outer container tries to restore to its original shape. However, the contents backflow prevention device (7) operates in response to the backflow of the contents and the contents of the outer container Since the flow path of the discharge nozzle is blocked, air does not flow from the outer container contents discharge nozzle, and air enters the air chamber through the air port (5). The volume of the content chamber (= inner container) (2) is reduced due to the tube portion being recessed by the amount of the content discharged. Since the contents reverse nozzle (7) acts to constantly fill the contents in the outer container contents discharge nozzle, air cannot flow into the contents chamber from the outer containers contents discharge nozzle. Therefore, the contents in the contents chamber can be used without being exposed to air even after the cap is opened, and deterioration of the contents can be prevented. When the contents were full, the tube part of the inner container was in contact with the wall of the outer container, but as the contents were discharged, the tube part of the inner container was dented according to the discharge amount, and the entire contents were discharged. At times, the tube portion is in perfect contact with the entire surface of the hard material portion of the inner container, and the space inside the inner container becomes zero. When the inner container is empty, the outer container can be reused by opening the outer container and replacing the empty inner container with a new inner container.
