Description

A device for removing the contents of a container

technical field

The present invention relates to a kind of utensil used in daily life which can take out the content in the container, especially the utensil with simple structure and convenient use.

Background technique

Due to the increasing abundance of daily life products, people will use more and more various containers, such as holding hand sanitizer, laundry detergent, disinfectant, shampoo, shower gel, toothpaste, soy sauce, vinegar, edible Containers for oil, liquid medicine, etc. Although these containers have different shapes, there are no more than two ways to take out the contents in the container: allowing the container opening to flow out the contents by itself; taking out the contents in the container with a presser.

Let the container open downwards to allow the contents to flow out. Containers used often have only one opening, and the opening is at the top. During use, the container must be tipped over so that the contents can flow out. Some containers also have to squeeze the walls of the container to allow the contents to flow out. This container has three disadvantages: 1. The method of taking out this container will inevitably cause external air and impurity particles to easily enter the interior of the container, making the contents contact with more gas, which may deteriorate due to oxidation and reduction by air, or Deterioration due to contamination by bacteria or impurities. 2. It is very inconvenient to take out the contents of these containers, such as shampoo and shower gel, it takes a long time to let the contents flow to the outlet after half of use, and it can be squeezed out for use. It is inconvenient to use, and the last part of the contents It may also be wasted. 3. Products (especially toothpaste) can only be used in small packages, and often cannot be fully squeezed out for use, which not only causes waste, but also produces a lot of packaging waste, causing pollution. 4. When this kind of container is taken out, due to the influence of many factors such as inclination, air flow, and opening size, the amount taken out fluctuates, which cannot be measured and is difficult to control accurately. In many cases, the contents have to be taken excessively, resulting in waste and waste. environmental pollution.

Using a squeezer to remove the contents of a container is another common method of removing the contents of a liquid. Especially for containers with large capacity and not suitable for inversion and extrusion, a presser is often used. This container also has 4 shortcoming: 1, the amount of taking liquid can not be accurately controlled. The downward pressing force of the presser cannot be accurately controlled, so the amount taken out can only be measured by the number of times of pressing, and the amount of liquid taken cannot be accurately controlled. 2. The viscosity and consistency of the liquid used should not be too high. Since the extractor needs to suck the liquid to a high place and then take it out, if the viscosity and consistency of the liquid are too high, the liquid cannot be sucked to a high place and cannot be taken out. 3. The manufacturing cost is higher. The structure of the extractor is complicated, and necessary parts such as the container wall cannot be used, and the manufacturing cost is relatively high. 4. Cannot be used continuously. Since the extractor can only take the content in the limited space near the outlet of the straw each time, the content in this space can only be taken out after being sucked from the container below again, so it can only be taken out. Take it intermittently, and take it out continuously.

People need a simple and practical container or utensil in daily life, so that each taking process can be controlled more freely by people, and it is less affected by external air or impurities.

Contents of the invention

In order to solve the problem that there is no convenient container and utensil for taking the content in the above-mentioned prior art, the present invention provides an utensil that can take out the content in the container. This utensil includes a pressurizing part, a pressure transmission channel , an outflow channel, the pressurizing part is used to pressurize the pressure transmission channel, the pressure transmission channel transmits the pressure exerted by the pressurizing part through the pressure transmission medium inside the channel, and the outflow channel is for the contents to flow out and A channel that can prevent the content from flowing backward; meanwhile, the appliance also includes an extraction part that accommodates the content, and the extraction part is connected to the pressure transmission channel; the extraction part is provided with a The opening through which the content communicates; when the pressurizing part is used to pressurize, the opening is closed under pressure, and the content in the fetching part passes through the The outflow channel flows out; the pressurizing part, the pressure transmission channel, and the fetching part are provided with a reset device and/or have the performance of elastic recovery, which can make the pressure transmission medium return to the position before the pressurization after stopping the pressurization .

The reset device is a device that can return to the original position and drive the pressure transmitting medium that transmits the pressure back to the initial position, such as a piston with one end fixed on the wall and pulled by an elastic member. The performance of elastic recovery refers to the elastic recovery of the pressurized part, the pressure transmission channel or the pick-up part after the pressurization is stopped, so that the pressure transmission medium that transmits the pressure returns to the original position.

This utensil can take out the content in the container conveniently, and can basically overcome the problems that the above-mentioned prior art exists.

Since it is only necessary to pressurize the contents of the extraction part and the outflow channel during pressurization, the required pressure is also very small, and the contents can be taken out conveniently; The amount will not fluctuate, can be precisely controlled, and the reproducibility of repeated use is very good.

When the utensil is used to take out the contents, since the container does not need to be turned upside down, the main body of the container does not need to be squeezed. This ensures that impurities such as air and particles do not frequently enter the main body of the container, preventing the contents from being polluted and deteriorated.

The appliance uses a pick-up part that is immersed in the content, and the opening of the pick-up part can be larger or even temporarily disconnected from the outflow channel, which can make it easier for liquids and pastes to enter the pick-up part, making the removal of viscosity and consistency Taller liquids and pastes are a reality.

Compared with the extractor, the device has a simpler structure and does not have too complicated and delicate parts, so it is also more practical and beneficial to large-scale production and overall production.

Further, the opening of the above-mentioned appliance is a one-way valve for the contents to enter the retrieval part from the container. The one-way valve for the contents to enter the retrieval part can be closed when pressurized, and opened under the influence of the gravity of the contents or the negative pressure of the retrieval part when not pressurized.

Further, the opening of the above-mentioned appliance is located on the wall of the extraction part; the plug closing the opening is located at a position corresponding to the opening, and the outside of the plug is connected to the elastic bladder; the elastic bladder The material communicates with the pressurizing part or the pressure transmission channel. The elastic capsule can expand and contract due to the pressure change of the space connected with it. When pressurized, the elastic bladder expands, and the plug is pushed to the opening to close the opening; when no pressure or negative pressure is applied, the elastic bladder shrinks, the plug is pulled, and the opening is opened.

Further, the opening of the above-mentioned appliance is located on the wall of the fetching part; the wall of the fetching part adjacent to the opening is provided with a groove, the groove has a built-in slide plate, and the bottom of the groove is connected to the pressurized Components or pressure channels are connected. The sliding plate protrudes or retracts due to a pressure change in a space communicating with the bottom of the groove. When pressurized, the pressure in the groove increases, the slide is squeezed and slides out, and the opening is closed; when there is no pressure or negative pressure, the pressure in the groove decreases, and the slide slides back into the groove.

Further, the opening of the above-mentioned device is a gap between the extraction part and the outflow channel; the extraction part or the pressure transmission channel is provided with a stretchable part, and the extraction part Or the stretchable part of the pressure transmission channel is stretched to close the gap. A gap between the extraction part and the outflow channel can make the content enter the extraction part more conveniently and fully; especially the paste with high viscosity and consistency can be absorbed without moving when pressurized. The pick-up part is included, and can be taken out smoothly after the opening is closed.

Further, the opening of the above-mentioned device is a gap between the object-retrieving part and the outflow channel; a sleeve is provided inside the object-retrieving part, and the sleeve slides out due to pressure changes on one side of the pressure transmission channel. Either slide in, closing or opening the gap. Similarly, when this embodiment is pressurized, the cannula can take the contents between the retrieval part and the outflow channel into the retrieval part without even moving the contents. With the inclusion of the retrieval unit, removal is easy.

Further, a piston that can slide inside the object-retrieving part of the above-mentioned appliance is provided, and the piston has an elongated outer surface, and when the outer surface of the piston moves to the opening, the opening is closed.

Further, a piston that can move back and forth along the object extraction part and/or pressure transmission channel is set in the object extraction part and/or pressure transmission channel of the above-mentioned appliance; The piston returns to a fixed initial position; a blocking element is set at a certain distance behind the object-taking part and/or the pressure transmission channel to prevent the piston from continuing to move after reaching this position. In this way, the content of the same volume can be taken out every time the pressure is applied, and the excessive amount can not be taken out, which plays the role of taking out in a limited amount.

Further, there is liquid in the pressurizing part and/or the pressure transmission channel of the above-mentioned appliance; the pressure part and/or the pressure transmission channel are marked with scales on the wall, which are used to indicate the volume of the liquid flowing out during pressurization. Due to the incompressibility of the liquid, the transmission pressure is more accurate and timely, and it can ensure that the volume of the liquid flowing out from the pressure transmission channel is equal to the volume of the content flowing out of the outflow channel when pressurized.

Further, a piston that can reciprocate along the object extraction part and/or pressure transmission channel is set in the object extraction part and/or pressure transmission channel of the above-mentioned appliance, one side of the piston is the pressure transmission medium, and the other side is the contained thing. Using the piston to transmit the pressure can clearly separate the interface between the pressure transmission medium and the contents, preventing contamination or air leakage.

Further, the pressure of the above appliance to close the opening may be the pressure difference between the pressure transmission medium in the pressurizing part and the content; or the pressure difference between the pressure transmission medium and the content in the pressure transmission channel ; or the pressure difference between the contents inside and outside the retrieval part. The pressure difference between the pressure transmission medium and the contents in the pressurizing part is the largest, the pressure difference between the pressure transmission medium and the contents in the pressure transmission channel is relatively large, and the pressure difference between the inner and outer contents of the extraction part is relatively small. Small. The maximum and larger pressure difference can make the opening and closing of the opening more timely and complete, preventing the contents from flowing out of the opening when pressurized. When the opening is closed by using the pressure difference between the inside and outside of the pick-up part, the overall structure of the appliance is simpler because the space between the two is relatively close, and no other parts need to be added.

The utensil capable of taking out the contents in the container has the advantages of simple structure, convenient use and wide application. The amount taken out by a single pressurization can be large or small; it can be taken out randomly or quantitatively according to experience; it can be used in both open containers and closed containers.

The present invention also provides a container with the above-mentioned utensil structure that can take out the contents in the container. This container for daily use contains the contents, including a container body, a pressurizing part, a pressure transmission channel, and an outflow channel. The pressurizing part is used to pressurize the pressure transmission channel, and the pressure transmission channel transmits the pressure exerted by the pressurizing part through the pressure transmission medium inside the channel, and the outflow channel is for the contents to flow out of the container body and can prevent The channel for the contents to flow back; moreover, it also includes an extraction part for containing the contents. The opening of the opening; when the pressurizing part is used to pressurize, the opening is closed under pressure, and the content in the fetching part flows out through the outflow channel under the pressure transmitted from the pressure transmission channel ; The pressurizing part, the outflow channel, and the fetching part are provided with a reset device and/or have elastic recovery performance, which can make the pressure transmission medium return to the position before the pressurization after stopping the pressurization.

The reset device and/or the performance of elastic recovery can allow the pressure transmission medium to flow back into the pressure transmission channel or the pressurizing component, so that the contents in the container can easily enter the retrieval component.

This container overcomes various problems that exist in the prior art container, and has the following advantages:

Easy to take out. Since the access part is located at the bottom of the container, even if the contents of the container are used to the end, it is as convenient as the first use.

Prevent pollution. When the device takes the contents, the container does not need to be turned upside down, and the air, bacteria, and particles will not frequently contact the contents, which can effectively prevent the contents from being polluted.

Can be taken out accurately. Since it is only necessary to pressurize a part of the content in the extraction part and the outflow channel, and the direction of the pressurization is consistent with the outflow direction of the content, the force required for pressurization is less, and accurate and quantitative extraction can be realized; Pressure requirements required for spray nozzles or foam generating devices.

The structure is simple, the practicability is strong, and it is not easy to be damaged. The extraction part is located inside the container, which reduces the amount of materials and can effectively prevent contamination and waste caused by leakage of the interface between the extraction part, the pressure transmission channel and the outflow channel.

It has a wide range of uses and can be used for contents with high viscosity and consistency.

Further, the pressure transmission medium in the pressure transmission channel of the above-mentioned container adjacent to the object retrieval component is the same as the content. Both have the same composition, which can prevent the content taken out from being polluted by the pressure transmission medium in the pressure transmission channel due to the difference in composition. Part of the liquid is the same, especially only part of the contact liquid is the same, which can reduce the cost.

Further, the said fetching part or outflow channel of the above-mentioned container is made of transparent material, and is marked with a scale indicating the volume or length of the outflowed content. In this way, the user can know the outflow amount in real time and realize quantitative consumption.

Further, the object-retrieving part of the above-mentioned container is located in the outer peripheral groove at the bottom of the container main body. With such an arrangement, the contents can be taken out smoothly even at the end of use, and it is convenient for the user to observe the conditions of the contents entering and flowing out of the fetching part.

Further, the pressure transmission channel of the above-mentioned container is the pressurizing component. If the pressure transmission channel can realize the pressurization function, the pressure transmission channel is also a pressurization part, and it can be considered that the pressurization part is saved in essence.

Further, there is liquid in the pressurizing part and/or the pressure transmission channel of the above-mentioned container, and a scale is marked on the wall of the pressurizing part and/or the pressure transmission channel, which is used to indicate the volume of the liquid flowing out during pressurization. volume. As mentioned above, due to the incompressibility of the liquid, the pressurizing part or the pressure transmission channel is filled with liquid, and the outflow volume of the pressurization part and the pressure transmission channel is equal to the outflow volume of the content in the outflow channel. According to the scale marked on the pressurized part or the wall of the outflow channel, the outflow amount of the contained content can be known, and quantitative removal can be realized.

Further, the pressurizing part of the above-mentioned container is in the shape of a straight cylinder, which is pressurized by a piston, and a scale is marked from the piston to the direction of the pressure transmission channel. The pressurized part has the advantages of simple structure, flexible operation and more intuitive quantification.

Further, the volume of the container body of the above-mentioned container decreases as the contents decrease. The driving force for reducing the volume of the container body is atmospheric pressure. When the content in the container decreases, the external atmospheric pressure presses the movable part of the container body to move, so that the volume of the container body decreases, the pressure inside and outside the container body is balanced, and the contents can be taken out continuously. Since the volume of the main body of the container is actively reduced, there is no opportunity for external gas or impurities to enter the interior of the main body of the container, which can completely prevent the contents from being polluted, oxidized, and deteriorated by external gases or impurities.

Further, the container body of the container is provided with a device for pressurizing the contents in the container body. The container body is equipped with a device for pressurizing the contents in the container body, which can reduce the volume of the container body, balance the pressure inside and outside the container body, and prevent the contents from being polluted, oxidized, and deteriorated by external gases or impurities. , and through active pressurization, the content can be more conveniently entered into the extraction part, which is more beneficial to take out the content with high viscosity and consistency.

Further, the container body of the above-mentioned container is provided with an inlet for outside air, and the inlet is an air filtration, purification or deoxygenation device, or an inflatable gas collection device is installed inside the container body of the inlet. This prevents the contents from being in contact with various harmful substances from the outside, and can prevent the contents from being polluted, oxidized, and deteriorated.

Further, the outflow port of the outflow channel of the container is equipped with a spray device or a foam generating device. Since the manual pressurization part can provide greater continuous pressure, and the pressure acts on the end of the pick-up part, a longer continuous spray or foam can be obtained during use.

This kind of container also overcomes various problems existing in the prior art container, and has the advantages of convenient taking out, pollution prevention, accurate taking out, simple structure, strong practicability, not easy to be damaged, and wide application. At the same time, the container has the characteristics of large capacity and recyclable use, which reduces the application of various packaging such as plastics, and is conducive to reducing the pressure of environmental pollution.

The present invention also proposes a method for taking out the contents in the container, comprising the following steps:

Use the pressurizing part to pressurize the pressure transmission channel to push the pressure transmission medium in the pressure transmission channel to move; the pressure transmission medium pushes the opening of the object extraction part in the container body to close; the pressure transmission medium pushes the The content moves outward along the outflow channel; the pressurizing part stops pressurizing, and the content in the fetching part stops flowing out; the pressure transmission medium flows back along the pressure transmission channel, and the fetching part The opening in the main body is opened; the content in the container main body enters the picking part from the opening of the picking part in the container main body.

Further, in this extraction method, a one-way valve is set in the outflow channel to prevent the contents in the outflow channel from flowing back. The one-way valve can realize automatic closing and opening, simple and practical, and not easy to be damaged.

Further, in this taking-out method, the pressure-transmitting medium prompts the closing of the opening of the picking-up component in the container body by pushing the picking-up component to stretch. The stretching method of the pick-up part closes the opening of the pick-up part in the main body of the container, and it can be included in the pick-up part without moving the contents, which is suitable for taking out the contents with large capacity, high viscosity or high consistency .

Further, in this extraction method, the pressure transmission medium pushes the valve to move to close the opening of the extraction component in the container body.

Further, in this extraction method, the expandable element is expanded to close the opening of the extraction component in the container body by pressurizing the pressure transmission medium.

Further, in this extraction method, negative pressure is generated through the pressurizing part or the pressure transmission channel to make the pressure transmission medium flow back along the pressure transmission channel.

Further, in this extraction method, a device for resetting the pressure transmission medium is arranged on the object extraction part or the pressure transmission channel, so as to promote the backflow of the pressure transmission medium.

Further, in this extraction method, the pressurizing part can generate negative pressure, and/or the extracting part or the pressure transmission channel is provided with a device for resetting the pressure transmission medium.

Further, in this extraction method, the pressurizing component and the pressure transmission channel are filled with liquid, and the volume of the extracted content is determined by squeezing the pressurizing component or the pressure transmission channel with equal volume.

Further, in this extraction method, the pressurized part and the pressure transmission channel are filled with gas, and the external outlet of the control airway that moves with the outflow of the content is set on the extraction part or the outflow channel, and the other outlet of the control airway is connected The volume of the contents taken out of the pressurizing part or the pressure transmission channel is determined by controlling the moving distance of the outer outlet of the airway. When the outer outlet of the controlled airway moves to a set position, the outer outlet of the controlled airway communicates with the outside air.

The method for taking out the contents of the container has simple steps, easy operation, accurate quantification and high reproducibility, and is very suitable for daily life needs.

Detailed ways

Example 1

As shown in FIG. 1 , it is a device that can conveniently take out the contents according to Embodiment 1 of the present invention. The appliance includes a pressurized air bag 101 , a pressure transmission channel 102 , an object extraction component 103 and an outflow channel 104 . The pressurized airbag 101 has only one opening leading to the pressure transmission channel 102 , which itself has the function of returning to its original shape, and can rebound after stopping the pressurization, so that negative pressure is generated in the pressure transmission channel 102 . The liquid 105 in the pressure transmission channel 102 is the same as the content. There is a piston 106 on the top of the liquid 105. The piston 106 separates the gas in the pressurized airbag 101 and the liquid 105 in the pressure transmission channel 102. A spring 113 is connected to the piston 106 , and the other end of the spring 113 is fixed on the inner wall of the pressure transmission channel 102 . The spring 113 has the same effect as the negative pressure generated by the pressurized air bag 101, so that the piston 106 in the pressure transmission channel 102 returns to the position before the pressurization after stopping the pressurization. The pressure transmission channel 102 is made of transparent material, with a scale 110 marked on the outer wall, the position of the piston 106 before pressurization is the origin, and other scales indicate the length of the scale from the origin or the length of the scale from the origin to transmit pressure The volume of liquid 105 within channel 102.

The diameter of the extraction part 103 is larger than the diameters of the pressure transmission channel 102 and the outflow channel 104 . At the bottom of the fetching part 104, there is an opening 107 consisting of a lower thinner upper upper thick pipe 108 and a spheroid 109 matched with the pipe 108. The opening 107 is closed when receiving the pressure that makes the content in the retrieval part 103 flow out, and opens when receiving the pressure that makes the external content flow into the retrieval part 103 .

A one-way valve 111 is provided in the outflow channel 4 to prevent the contents from flowing backward. At the opening of the outflow channel 104, a spray nozzle 112 is provided.

When using the utensil, firstly, the pick-up part 103 of the utensil is submerged in the content, so that the content enters the pick-up part 103 from the opening 107 . Squeeze the pressurized airbag 101 , push the piston 106 to move downwards, and make the liquid 105 in the pressure transmission channel 102 move to the pick-up part 103 . The sphere 109 in the opening 107 falls under the pressure of the contents in the fetching part 103 to block the pipeline 108 . The pressure closing the opening 107 is the pressure difference between the contents inside and outside the retrieval part 103 . The content in the pick-up part 103 flows outward along the outflow channel 104 under the action of pressure, and is sprayed out after being atomized by the spray nozzle 112 . When the piston 106 moves to the desired volume scale, the pressurization is stopped, and the contents stop ejecting. The pressurized air bag 101 rebounds, and the spring 113 recovers, so that the piston 106 and the liquid 105 return to the position before the pressurization, the one-way valve 111 is closed, a negative pressure is generated in the fetching part 103, the ball 109 rises, and the opening 107 is opened. The content flows into the retrieval part 103 . The appliance is ready for the next removal.

Example 2

As shown in FIG. 2 , it is a utensil according to Embodiment 2 that can conveniently access the contents. The appliance includes a container pressurizing part 201 , a pressure transmitting channel 202 , an object picking part 203 and an outflow channel 204 .

The pressing part 201 includes a piston 211 , a handle 212 and a return spring 213 .

The pressure transmission channel 202 is made of partially transparent material, so that the position of the piston 211 can be seen. From the lower part of the original position of the piston 211, scales are marked sequentially, and corresponding volumes are marked. A liquid 221 is contained in the pressure transmission channel 22 , and the liquid 221 is separated from the content 205 by the piston 222 . The piston 222 can move left and right in the pressure transmission channel 202 and the object retrieval part 203 under the action of pressure. The pressure transmission channel 202 has a branch channel 223, and a piston 224 is provided at the terminal opening of the branch channel 223, and the piston 224 can move up and down within a certain range at the terminal end of the branch channel 223 under the action of pressure. A plug 226 is arranged above the piston 224 . The spring 225 pulls the piston 224 back to its original position when the pressure in the branch passage 223 drops to a certain extent.

The inner diameter of the pick-up part 203 is the same as that of the pressure transmission channel 202 , and an opening 207 is arranged at its lower part, and the shape of the opening 207 matches the plug 226 . The opening 207 is located above the plug 226, and the plug 226 can block the opening 207 when the piston 224 moves upward.

A one-way valve 206 is provided in the outflow channel 204 to prevent the contents from flowing back.

When the device is used to take out the content 205, the piston 211 is pushed downward by pressing the handle 212 downward, so that the liquid 221 in the pressure transmission channel 202 is pressed and flows downward. The piston 224 in the branch channel 223 is pressed and moves upwards, so that the plug 226 blocks the opening 207 of the extraction part 203 . The pressure to close the opening 207 is the pressure difference between the pressure transmission medium 221 and the content 205 outside the retrieval part 203 . The piston 222 moves toward the pick-up part 203 under pressure, pushing the content 205 in the pick-up part 203 to flow out along the outflow channel 204 . When the piston 211 moves to a predetermined position, it stops moving downward, and the contents 205 stop flowing out.

When the pressurization is stopped, the return spring 213 pushes the handle 212 to move upwards, driving the piston 211 to gradually return to the original position before pressurization. The liquid 221 in the branch channel 223 and the pressure transmission channel 202 flows back. The pressure in the branch channel 223 drops, and under the action of the spring 225, the piston 224 moves downward, and the opening 207 opens. The pressure in the pressure transmission channel 202 drops, the piston 222 moves toward the pressure transmission channel 202 , and the pressure in the pick-up part 203 decreases. Since the one-way valve 206 in the outflow channel 204 is closed, the content 205 outside the object extraction part 203 enters the object extraction part 203 along the opening 207 under pressure. The appliance is ready for the next use.

Example 3

As shown in Fig. 3 and Fig. 4, it is an appliance according to the embodiment 3 that can conveniently access the contents, and Fig. 4 is an enlarged view of part A of Fig. 3 . The appliance includes a pressurized air bag 301 , a pressure transmission channel 302 , an object retrieval component 303 and an outflow channel 304 . The pressurized airbag 301 has only two openings leading to the pressure transmission channel 302 and the control air channel 305 . The pressurized airbag 301 has the function of returning to its original shape, and can rebound after stopping the pressurization, so that negative pressure is generated in the pressure transmission channel 302 and the control air channel 305 .

The pressure transmission medium 311 in the pressure transmission channel 302 is the content. The pressure transmission channel 302 communicates with the object retrieval component 303 . The outer wall of the pressure transmission channel 302 is marked with a scale 310 indicating the volume of the pressure transmission medium 311 flowing out of the pressure transmission channel 302 when pressurized. This outflow volume is also the volume through which the contents flow out from the outflow channel 304 .

The inner wall of the tail end of the control air passage 305 is connected to the elastic member 306, and the other end of the elastic member 306 is connected to the handle end 312 of the sliding piece 308. There is an airtight seal between the channels 305. An opening 307 is arranged on the side wall of the fetching part 303 , and there are slideways 313 on both sides of the opening 307 on the side wall of the fetching part 303 . The sliding piece 308 can slide along the slideway in the slideway 313 .

The outflow channel 304 communicates with the extraction part 303 and has a one-way valve 309 inside.

When using the appliance to take the content, squeeze the pressurized air bag 301, the gas reaches the handle end 312 through the control air passage 305, and the slide plate 308 is pushed to move along the slideway 313 through the handle end 312, and the slide plate 308 moves to the left, closing Opening 307 is opened. The pressure for closing the opening 307 is the pressure difference between the pressurizing part 301 and the content outside the object taking part 303 . The pressure transmission channel 302 is pressurized so that the pressure transmission medium 311 (ie, the content) moves downward, and the content flows out through the extraction part 303 and the outflow channel 304 .

After taking out the required volume, stop squeezing the pressurized airbag 301, and the pressurized airbag 301 will rebound to generate negative pressure. As the internal pressure of the control airway 305 drops and the elastic member 306 is retracted, the handle end 312 is retracted. The slide 308 moves to the right along the slideway 313 to open the opening 307 . The pressure transmission medium 311 in the pressure transmission passage 302 flows back under negative pressure, the valve 309 is closed, and the content in the container body enters the object extraction part 303 through the valve 307 . The pressure transmission medium 311 in the pressure transmission channel 302 returns to the position before pressurization. The appliance is ready for the next use.

Example 4

As shown in FIG. 5 , it is a container that can conveniently access the contents according to Embodiment 4, and FIG. 6 is an enlarged view of part B of FIG. 5 . The container includes a container body 415 with an opening 414 therein. After filling the contents 410, the opening is closed with a device that prevents bacteria and dust but allows a small amount of gas to enter, such as a device comprising a porous body or a filter membrane. The pressurizing component 401 includes a pressurizing chamber 416 and a piston 417 on the pressurizing chamber 416 that can move up and down. The piston 417 seals the pressurized chamber 416 , and a part of the upper part of the pressurized chamber 416 is exposed. The pressurized chamber 416 communicates with the pressure transmission channel 402 , both of which are filled with the same liquid 411 . The pressure transmission channel 402 is provided with a piston 405 , and the piston 405 can move in a part of the space between the pressure transmission channel 405 and the object retrieval component 403 . The right side of the piston 405 is the liquid 411 (pressure transmission medium), the left side is the content 410 , and the right side is connected with a spring 406 whose other end is fixed on the inner wall of the pressure transmission channel 402 .

At a specific position on the left side of the piston 405 inside the fetching part 403, a blocking part 408 is provided to prevent the piston 405 from continuing to move leftward after arriving here under the action of pressure. There is an opening 407 at the bottom of the fetching part 403 . A plug 412 is provided in the opening 407 , and when the plug 412 falls on the opening 407 , the opening 407 can be sealed. The stopper 412 has a longer tail end, which can prevent the stopper 412 from leaving the position where the opening 407 is when it rises. The opening 407 is located in the recess 413 at the lowest part of the container body 415 .

An outward one-way valve 409 is arranged inside the outflow channel 404 .

When using the container, each time the piston 417 is depressed, a fixed volume of the contents can be obtained. The specific operation is as follows:

Pressing down on the piston 417, the liquid 411 in the pressurizing chamber 416 and the pressure transmission channel 402 is pressed to move, pushing the piston 405 to move to the left, the plug 412 is pressed to block the opening 407, and the piston 405 pushes the content 410 in the pick-up part 403 Flow out along the outflow channel 404 . The pressure closing the opening 407 is the pressure difference between the contents inside and outside the retrieval part 403 . When the piston 405 moves to the position where the blocking member 408 is located, the piston 405 stops moving, and the contents 410 in the container body 415 stop flowing out. The outflow volume is the volume of content between the piston 405 and the blocking member 408 before pressurization.

Stop pressurizing the piston 417, the piston 405 returns to the original position under the action of the spring 406, and the liquid 411 and the piston 417 are pushed back to the original position. As the valve 409 is closed, a negative pressure occurs in the extraction part 403 , the plug 412 is pushed up and opened, and the content 410 in the container body 415 enters the extraction part 403 along the opening 407 . The external air with the same volume as the taken-out content enters the upper part of the main body of the container through the opening 414, and the internal and external pressures are gradually balanced, and the container is ready for the next time it is taken out.

Example 5

As shown in FIG. 7 , it is a container according to Embodiment 5 that can conveniently access the contents. The container includes a container body 515 with an opening 514 defined therein. The opening 514 is closed after filling the contents 508 to prevent any substance from entering the container body 515 . The upper part of the container body 515 is made of soft material, and the volume of the container body 515 decreases with the reduction of the volume of the contents under the action of atmospheric pressure.

The pressurized air bag 501 has only one opening to the pressure transmission channel 502 . The pressurized airbag 501 has the function of returning to its original shape, and can rebound after stopping the pressurization, so that negative pressure is generated in the pressure transmission channel 502 . There are two pistons (piston 511 and piston 512) in the pressure transmission passage 502, between the two pistons is a pressure transmission medium 513, and the lower part of the piston 512 is a pressure transmission medium 508 (that is, the content 508), wherein the piston 511 and the pressure transmission medium The frictional force of the channel 502 is smaller than the frictional force between the piston 512 and the pressure transmission channel 502 . The position where the piston 512 is when no pressure is applied is the origin, and a scale 510 is marked downward, showing the volume of the contents from the piston 512 to this point. The pipeline 505 is located in the pressure transmission channel 502 and passes through the piston 512 to communicate with the pressure transmission medium 513 and the inflatable bladder set 506 . The inflatable capsule group 506 is located at the end of the pressure transmission channel 502 and is connected to the extraction part 503 . The expandable capsule ring group 506 will expand after being filled with the pressure transmission medium 513, and will retract when not pressurized.

There is a gap 507 between the fetching part 503 and the outflow channel 504 when the inflatable sac group 506 is not inflated. When inflated, the fetching part 503 is pushed to move to the left, and is sleeved and connected with the initial end of the outflow channel 504. There is no gap between the two. There is another gap. A one-way valve 509 is arranged in the outflow channel 504 .

When the container is used to take the contents, the pressurized air bag 501 is squeezed, the piston 511 is pressed and moves downward, and the pressure transmission medium 513 between the piston 511 and the piston 512 is pressurized and enters the expandable bag ring group 506 through the pipeline 505, The inflatable capsule ring group 506 expands, pushes the retrieval part 503 to move to the left, and sleeves with the starting end of the outflow channel 504, and the opening 507 is closed. The pressure to close the opening 507 is the pressure difference between the pressure transmission medium 513 and the contents outside the object extraction part 503 . Subsequently, the pressure transmission medium 513 transmits the pressure of the piston 511 to the piston 512 and the pressure transmission medium 508, and the content 508 in the retrieval part 503 flows out through the outflow channel under pressure. When the piston 512 moves to the target position, the pressurization is stopped, and the contents 508 stop flowing out.

Stop squeezing the pressurized airbag 501, the pressurized airbag 501 rebounds, the piston 511 moves upward, the pressure between the piston 511 and the piston 512 decreases, the pressure transmission medium 513 flows back, the inflatable bag ring group 506 retracts, and the fetching part 503 The opening 507 between the outlet channel 504 and the outflow channel 504 is open. Subsequently, the piston 512 also moves upward due to the negative pressure, and the pressure transmission medium 508 moves upward. Valve 509 is closed. The content 508 in the container body 515 enters the retrieval part 503 from the opening 507 . The pressurized airbag 501 recovers, and the piston 511, the pressure transmission medium 513, the piston 512 and the pressure transmission medium 508 return to the positions before pressurization. The upper soft part of the container main body 515 falls, and the container main body 515 is reduced by a volume equal to that of taking out the contents. The internal and external pressures of the container main body 515 are gradually balanced, and the container is ready for taking out next time.

The method for balancing the internal and external pressure of the container body 515 also includes installing a piston on the container body. When the contents of the container body are gradually taken out, the piston gradually moves into the container body under the action of atmospheric pressure to reduce the volume of the container body.

It is also possible to install a handle on the piston on the container main body, and pressurize the content in the container main body through the handle. Such setting can not only keep the internal and external pressure of the container in balance after the contents are taken out, but also help to promote the contents in the container to enter the fetching part.

Example 6

As shown in FIG. 8 , it is a container that can conveniently access the contents according to Embodiment 6, and FIG. 9 is an enlarged view of part C of FIG. 8 . The container includes a container body 612 with an opening 613 defined therein. The opening 613 is closed with a multi-layer one-way paper valve that allows a small amount of gas to enter. The pressurizing part 601 is an elongated elastic bladder (also a pressure transmission channel), with only one opening communicating with the object retrieval part 603 and filled with the pressure transmission medium 602 .

The pick-up component 603 is located on the slide rail 605 and can slide left and right along the slide rail 605 . The slide rail 605 is located on the inner wall of the tail of the pressure transmission channel. The object picking part 603 is sealed with the inner wall of the tail of the pressure transmission channel, and the contents and the pressure transmission medium 602 cannot pass through. The piston 606 is located in the pick-up part 603 and can move left and right in the pick-up part 603 . The frictional force between the fetching part 603 and the slide rail 605 is smaller than the frictional force between the piston 606 and the fetching part 603 . The right end of the piston 606 is connected to the inner wall of the pressure transmission channel through the elastic member 610 . When no pressure is applied, there is a gap between the object extraction part 603 and the outflow channel 604 , that is, an opening 607 . When pressurized, the pick-up part 603 slides out and fits with the sleeve head 608 at the beginning of the outflow channel 604, and the opening 607 is closed. There is a one-way valve 609 in the outflow channel 604, and a foam production device 614 is installed at the outflow port.

When the container is used to take the contents, the pressurized air bag 601 is squeezed, and the pressure transmission medium 602 inside is pressed and moves downward. The pick-up part 603 moves to the left along the slide rail under the action of the pressure, fits with the sleeve head 608 at the beginning end of the outflow channel 604 , and closes the opening 607 . The pressure is the pressure difference between the pressure transmission medium 602 and the contents. As the pressure increases, the piston 606 is pressed and moves to the left, pushing the content 611 in the pick-up part 603 to flow out after being turned into foam through the outflow channel 604 and the foam production device 614 .

Stop extruding the pressurized airbag 601, the pressurized airbag 601 rebounds, the pressure transmission medium 602 moves upward, and the fetching part 603 and the piston 606 move to the right under the action of the negative pressure and the elastic part 610, and the fetching part 603 and the outflow channel The opening 607 between 604 is open. Valve 609 is closed. The content 611 in the container body 612 enters into the extraction part 603 from the opening 607 . The pressurized airbag 601 recovers, and the pressure transmission medium 602, the piston 606 and the object retrieval part 603 return to the positions before pressurization. The external air with the same volume as the taken out contents enters the upper part of the main body of the container through the opening 613, and the internal and external pressure gradually balances, and the container is ready for the next time taken out.
