Description

  The present invention relates to a dispenser container capable of taking out a certain amount of liquid contents filled in a container.

  Conventionally, various dispenser containers have been used in order to take out and use a certain amount of content liquid so as to represent shampoo, rinse, and mouthwash. These methods of use require use of both hands, such as pushing the dispenser pump with one hand and receiving the liquid with one hand, or holding it with one hand and receiving the liquid into the container.

  Recently, as a measure to prevent the spread of infectious diseases, it is said that gargles and hand-washing are encouraged, and there are many cases where disinfecting ethanol is installed at the entrances of facility buildings. However, most of them are diverted from ordinary pump dispenser containers, and there is an inconvenience that it is difficult to say that the operation method and the discharge amount are suitable for this application. In particular, in the operating method, you must push the pump with one hand, and you must free both hands to receive the liquid content with one hand. It can be seen that it takes time just to wash and queues for washing.

  In addition, since a large amount of liquid is produced at a time, it is necessary to finely adjust the stroke of the dispenser in order to adjust the liquid amount, and there is a problem that clothes are discolored due to excessive dispensing.

  Commercially available dispensers can be used for bactericidal chemicals in which the nozzle is extended in the lateral direction to facilitate operation, but the operation method is inconvenient and not different from the conventional one.

  Ordinary shampoos and rinses have the same inconvenience. For example, when washing hair with a shower nozzle in one hand, the shower nozzle must be placed once.

  Moreover, the container which devised the attachment method so that the direction of a dispenser can be changed freely is proposed (patent document 1).

  This is a proposal that has a neck that can be stretched and bent to connect the trigger spray member and the container, and can be operated at various angles, but there are also inconveniences such as using both hands.

  There is a demand for a dispenser container that can be pumped with one hand and has the convenience of receiving liquid contents in its palm.

  The present invention is a dispenser container composed of a container having a bellows-shaped side surface and a cap having a liquid content discharge device attached to the inside of the container, and the liquid content rises by pushing down the bellows container that also serves as a pump. It is possible to discharge the liquid content from the nozzle of the cap to the palm, that is, it is possible to operate with one hand. Since the discharge speed of the solution in the liquid is also low, the amount can be easily adjusted. Moreover, since the bellows container is gradually deformed downward as it is discharged, it is a dispenser container that serves as a measure of the replenishment timing of the liquid contents.

According to the first aspect of the present invention, a dispenser container comprising a container 1 having a bellows-shaped side surface and a cap 2 having a liquid content discharge device 3 attached to the inside of the container, the horizontally disposed container 1 is directed downward. By deforming, the internal pressure of the container rises and the liquid content is discharged upward from the nozzle 21 provided in the cap 2. According to the present invention, the liquid content can be taken out, that is, the cap can be pushed by the palm and the liquid content can be received by the pushed palm. That is, it can be used with one hand without using both hands.

Further , the liquid content discharge device 3 is attached so that the main body 31 and the lower end are below the liquid level of the content and the upper end is closed and the horizontal pipe 321 is opened and the transfer pipe 32 made of rubber is covered with the rubber. When a pressure in the container of a certain value or more is applied, the valve 341 composed of both opens and the liquid contents are discharged through the horizontal hole. The horizontal hole is covered with a cover pipe, and the cover pipe is usually in close contact with the horizontal hole and closed. When a pressure in the container above a certain level is applied, the cover pipe that has been tightly closed by the pressure of the liquid content portion opens (the valve opens), and the liquid content flows into the chamber through the side hole. In the upper center of the chamber, there is a supply port for supplying to a nozzle provided in the center of the cap. The supply port is transmitted to the nozzle through the supply port, and the liquid content can be discharged upward from the nozzle. Further, it is possible to design a desired discharge amount by the size of the opening diameter of the horizontal hole, and the user can adjust the pressing pressure and pressing time of the container by the user himself.

Further , a supply chamber 332 is provided in a portion where the horizontal hole 331 at the upper end of the transfer pipe 33 is opened. In the supply chamber 332 having a horizontal hole, the liquid content pushed up by the liquid pressure proceeds to the horizontal hole through the supply chamber 332 when a pressure in the container of a certain level or more is applied.
When the weight for pressurizing the container is removed, the internal pressure is lowered, the lateral hole 331 is blocked by the cover pipe 34, and the supply is stopped. At this time, the raised liquid content can be kept in the supply chamber 332 so that it does not fall down through the transfer pipe. By keeping the liquid content in the supply chamber, the discharge can be stably performed.

According to claim 2 of the present invention, as the liquid contents are discharged, the deformation of the container proceeds to make the head space capacity constant, and the manner in which the internal pressure of the container rises is constant regardless of the remaining amount of the liquid internal solution. It is characterized by being. In a normal container, outside air flows in to prevent deformation under reduced pressure due to a decrease in the liquid content. It has a feature that it can be used with a constant feeling.

According to claim 3 of the present invention, the dispenser container is characterized in that the top surface portion 22 at the periphery of the cap 2 is located higher than the nozzle 21 and the liquid content liquid is discharged upward. It is possible to discharge the liquid contents to the palm while pushing the top surface of the periphery of the cap with the palm. For example, when taking out the liquid contents, it is possible to operate and receive the liquid with only one hand.

According to claim 4 of the present invention, the cap 2 and the main body 31 of the liquid contents discharge device 3 are screwed together. Attachment can be facilitated by screwing together the main body and cap of the pre-assembled contents discharge device.

According to claim 5 of the present invention, the nozzle 21 is sealed by the seal label 4 that seals from the outside of the nozzle. After filling the liquid contents of the bellows container, a cap assembled with the liquid contents discharge device is attached, and then a seal label 4 for sealing from the outside of the nozzle is attached to the nozzle 21. This seal label protects the liquid contents and maintains the quality.

According to claim 6 of the present invention, the seal label 4 includes a base material layer 41 and a sealant layer 42 having an easy peel property. By using a sealant layer having easy peel properties, the seal label with the nozzle sealed can be easily opened.

It is explanatory drawing which shows an example of a structure of a seal label.

  Hereinafter, modes for carrying out the present invention will be described.

  The structure plan will be described in detail based on the above contents. FIG. 1 is an explanatory view showing an example of a dispenser container of the present invention.

  The dispenser container A of the present invention includes a cap 2 in which the container 1 and the liquid content discharge device 3 are assembled inside the container, and a seal label 4 that seals the nozzle to be discharged. The container 1 and the cap 2 are combined with each other by screw type or fitting, and have a liquid stop function and can be detached. The content liquid can be replenished by removing the cap.

  The liquid content discharge device 3 will be described. The liquid content discharge device 3 includes a main body 31, a chamber 32, a transfer pipe 33, and a cover pipe 34. The main body 31 has a chamber 32 provided with a supply port 321 for supplying the liquid content to the nozzle. Includes a transport pipe 33 having a lower end below the liquid level of the contents and a closed upper end and having a horizontal hole 331 and a cover pipe 34 made of rubber and attached so as to close the horizontal hole 331. . The horizontal hole 331 and the cover pipe 34 form a valve 341.

  The container 1 can be used as long as it can stand upright with an accordion-shaped container such as an injection molded product, a film container, in addition to a normal direct blow molded product and a stretch blow molded product. The material of the container 1 can be polyethylene, polypropylene, polyester, or a container multilayered with an ethylene / vinyl copolymer, polyamide, or the like as a structure for providing a barrier using these as a base material. Moreover, what is necessary is just to select the resin of the innermost layer according to the tolerance of the liquid content.

The material of the cap is a polyolefin resin such as polyethylene or polypropylene.
Also, each member of the content discharge device can be a polyolefin resin such as polyethylene or polypropylene, or a polyethylene terephthalate resin.

  Further, the mouth portion of the container 1 and the cap 2 can be attached by screwing or fitting using a packing. By screwing with a screw type, the liquid contents can be easily removed when being refilled.

  The lateral hole 331 and the cover pipe 34 are assembled to form a valve 341. The parts of the cover pipe 34 are made of a material such as rubber that has a large amount of deformation. The contents discharge device 3 can use metal parts depending on the parts, but it is desirable to have a part structure that is as light as possible when the center of gravity of the entire container is high and the upright state is unstable.

  The liquid content discharge device can be obtained by injection molding the main body 31, the chamber 32, etc. using a polyolefin resin such as polyethylene or polypropylene. The conveying pipe is a pipe made of a polyolefin resin such as polyethylene and polypropylene, and the inner diameter and outer diameter may be appropriately determined depending on the type of liquid content to be used, the amount to be discharged, and the like. The horizontal hole at the top of the transport pipe can be drilled by laser cutting or punching. These parts can be assembled and produced using heat fusion or an adhesive.

  Further, the cap 2 and the main body 31 of the liquid content discharge device are screwed together and are easily assembled by fitting.

  FIG. 2 shows the liquid content discharge device 3 of FIG. 1 provided with a supply chamber 332 having a horizontal hole 331 formed at the upper end of the transport pipe. The supply chamber can be prepared by preparing in advance by injection molding, incorporating a transport pipe into the molded body, and assembling the chamber and the main body.

  FIG. 3 is an explanatory view showing an example of a cap in which the liquid content discharge device shown in FIG. It shows after the seal label of the nozzle has been removed.

  FIG. 4 is an explanatory view showing an example of a state in which the liquid content is discharged from the nozzle by the cap to which the liquid content discharge device shown in FIG. 2 is attached. When a pressure in the container equal to or greater than a certain value is applied, the valve 341 is opened, and the liquid content is discharged upward from the nozzle 21 through the lateral hole 331.

Next, a process until the liquid comes out will be described. When the top surface portion B on the periphery of the cap is pressurized, the air in the head space (not shown) is compressed to increase the pressure, which is transmitted to the liquid content liquid, and the liquid pressure similarly increases. When this pressure becomes higher than the pressing pressure of the cover pipe 34, the liquid content fills the main body chamber 32 at a high pressure from the lateral hole 331 and is ejected upward from the nozzle 21 through the supply port 321. The flow of the liquid contents is indicated by C. Here, when the load for pressurizing the container 1 is removed, the internal pressure is lowered, the lateral hole 331 is closed, and the discharge of the liquid stops. The internal pressure of the container at this time is determined by the balance between the pressure of the trapped air and the restoring force of the container, and the internal pressure approaches the initial pressure as the container easily deforms. The closer the initial pressure is, the more nearly the relationship between the feeling of pushing the container 1 and the discharge amount is constant.

  In the supply chamber 332 having a horizontal hole, the liquid content pushed up by the hydraulic pressure passes through the supply chamber 332 to the horizontal hole. When the load that pressurizes the container 1 is removed, the internal pressure decreases, the lateral hole 331 is blocked by the cover pipe 34, and the supply stops. At this time, the raised liquid content can be kept in the supply chamber so as not to fall down from the transfer pipe.

  FIG. 5 is an explanatory diagram illustrating an example of a state in which the liquid contents are discharged from the nozzle in the dispenser container illustrated in FIG. 2. The top surface B of the peripheral edge of the cap is pressurized with a palm, the container is deformed, the internal pressure of the container is applied, the liquid pressure is increased, and the liquid content is discharged upward from a nozzle provided in the cap through the transport pipe. Therefore, the liquid content can be received in the palm. One-handed operation and liquid reception can be performed with one touch.

  FIG. 6 is an explanatory view showing an example in which the suction member D is mounted on the outside of the bottom of the dispenser container of the present invention. By providing the adsorbing member D, a sense of stability is obtained by adsorbing and connecting with other members, and it becomes difficult to fall down and is easy to use. This stabilizes the upright position. The adsorbing member D to be used can be a double-sided adhesive tape or the like as an adsorbing connection member between the container and the adsorbing member and the adsorbing member and the other member, but an adsorbing board made of rubber or urethane can also be used. As shown in FIG. 6, it is preferable that the suction plate D is used to suck and fix the bottom surface of the container and other stable members for easy handling. In the case of liquid contents with high viscosity such as shampoo and rinse, the liquid contents can be easily discharged by sticking the suction disk to the wall and ejecting it horizontally. In this case, in order to prevent the container from falling, it is more stable if a container holder is provided on the wall. The container holder can be attached by using a suction disk.

  FIG. 7 is an explanatory diagram showing an example of the configuration of the seal label. As the seal label 4 for sealing the nozzle, a laminate including at least a base material layer 41 and a sealant layer 42 having an easy peel property is used. As the base material layer 41, a stretched polyethylene terephthalate film, a stretched polypropylene film, a stretched nylon film, a stretched polyethylene naphthalate film, a silica vapor deposition stretched polyethylene terephthalate film, an alumina vapor deposition stretched polyethylene terephthalate film, a stretched silica vapor deposition stretched nylon film, an alumina vapor deposition stretch Nylon film, silica vapor-deposited stretched polyethylene naphthalate film, alumina vapor-deposited stretched polyethylene naphthalate film, thickness 10 μm to 50 μm, preferably 10 μm to 30 μm.

  As the sealant layer 42, a resin having an easy peel property is used. As the sealant layer having easy peel properties, there are a cohesive failure type, an interlayer peeling type, and an interface peeling type.

  The cohesive failure type is a type in which the sealant layer itself cohesively breaks. Using a resin mixed with resin such as polypropylene, polyethylene, polystyrene, etc., it is formed into a film and laminated on the base material layer, or the coating solution of this resin is used. It can be used by coating.

  For example, a resin in which a polyolefin resin such as polyethylene, high-density polyethylene, linear low-density polyethylene, or polyethylene is mixed with a polybutene resin, or a resin in which a polyolefin resin and a polystyrene resin are mixed can be used.

The delamination type is a method in which a three-layer film is prepared by a coextrusion method and is peeled from an intermediate layer. This coextruded film can be used by being laminated on a base material layer.

  The interfacial peeling type can be used by forming a film using a resin in which the mixing ratio of the vinyl acetate of the ethylene-vinyl acetate copolymer resin is increased and laminating it on the base material layer.

  Any of the above three types can be used as the sealant layer having easy peel properties. According to the material used for the cap, the thickness of the sealant layer may be appropriately determined from peel strength, peelability, and the like.

  The seal label for sealing the nozzle can be attached by applying heat pressure to the seal label so as to cover the nozzle portion of the cap and heat-sealing. Further, when the cap is formed by injection molding, the seal label can be placed in the mold so that the label covers from the outside of the nozzle, and can be heat-sealed and bonded simultaneously with the injection molding. That is, the seal label can be attached by an in-mold method. Further, by providing an unsealed portion at either end of the seal portion between the seal label and the nozzle portion, the unsealed portion of the seal label can be easily picked off with a finger when the container is opened.

  The feature of the present invention is that the operation and the operation time can be shortened by operating the container and receiving the liquid contents with one hand. For this reason, for example, the alcohol for sterilization installed at the entrance of the facility can be taken out smoothly, and a person can enter the facility smoothly without forming a line. It is also easy to take out the shampoo while holding the shower nozzle. Also, even if you are injured by injuring one hand, you can remove it with one hand, so there is no difference in usability with healthy people.

  In addition, the feature of the present invention is that the conventional dispenser sucks and accumulates the liquid contents and then pushes it out, so it is difficult to finely adjust the discharge amount. Since the flow path can be designed without considering sucking up, the dimensions according to the purpose of use can be freely determined. Here, the hole diameter of the horizontal hole greatly affects the discharge speed. This structure can be used from a very small amount to a large amount at a time.

  Further, the present invention is characterized in that the proposed dispenser container has a high storage efficiency and a low transportation cost because the dispenser does not protrude from the container. Moreover, even if it falls, the dispenser does not directly hit the floor, so the risk of breakage is low. Further, since the container has a soft structure, the container itself has a high impact resistance.

  Specific examples will be described below.

  A wide-mouthed bellows-type container having a filling volume of 500 ml, a full capacity of 550 ml, and an outer diameter of 70 mm was assembled with a cap and packing assembled with a content discharge device interposed therebetween. The nozzle position was provided at a position 10 mm lower than the top surface of the peripheral edge of the cap. The inner diameter of the horizontal hole was set to discharge 2 ml when the top surface of the peripheral edge of the cap was pressed for about 1 second with a load of about 0.5 Newton. The liquid contents were filled with sterilizing ethanol.

  This container was installed on the right side facing the wall that was designed as a facility entrance. Thirty testers who experienced the above operating conditions in a row were arranged in a line, and the body was operated with the palm of the right hand and the top surface of the periphery of the cap with the front facing the wall. The liquid contents were received and 30 people performed this operation continuously. Table 1 shows the total time and the total amount used.

  In Example 1, the same measurement as in Example 1 was performed using the left hand with the container installed on the left side facing the wall as if it were the entrance, and the results are shown in Table 1.

  In Example 1, the nozzle extension part is assembled to the cap nozzle, changed so that it drops from above the top surface of the peripheral edge of the cap, and the back of the hand of the right hand is used by using the container installed on the right side facing the wall that looks like the entrance. The same measurement was performed using and the results are shown in Table 1.
