Description

The present invention relates to a chemical solution container having a function of spraying various chemical solutions such as nasal drops.

Nasal drops are drugs that are absorbed by the mucous membrane of the nasal cavity, and products used for improving nasal congestion are widely used. At the distribution stage, they are often enclosed in nasal drops containers. A nozzle is incorporated in this nasal spray container, and when the tip of the nozzle is directed toward the nasal cavity and then the button or the side surface of the container is pressed, the chemical solution is sprayed from the nozzle and the active ingredient is absorbed by the body. Generally, a nasal spray container has a shape similar to that of an eye drop container, and a drug solution is stored in a lower body, a tubular neck is formed above the body, and a nozzle is incorporated at the tip of the neck. In addition to the nasal spray container, there are many chemical solution containers having a function of spraying the chemical solution.

As an example of the technique relating to the nasal spray container, Patent Document 1 described later can be mentioned. In this document, a powder nasal spray spray container is disclosed, which is characterized in that the spray amount can be made substantially constant. A powder discharge pipe connecting the nostril nozzle and the powder storage chamber is incorporated in the center of the container, and a hollow powder storage hole is provided in the lower part of the powder storage chamber. Further, the powder discharge pipe can be rotated from the outside, and the flow path between the powder storage chamber and the powder storage hole can be freely opened and closed. Therefore, by rotating the powder discharge pipe, a certain amount of chemicals can be stored in the powder storage hole, and the spray amount becomes almost constant.

Non-Patent Document 1 described later is an example of a technique related to the present invention. In this document, a packaging container in which six container bodies containing chemicals are connected in the horizontal direction is disclosed. When in use, only one container body is separated and its pull tab is separated to obtain a chemical solution. Can be dropped. Since this packaging container is molded and injected with chemicals at the same time during manufacturing, there is no room for germs to enter inside, and the capacity of each container is relatively small, so it is possible to consume all of the chemicals at once. As a premise.

FIG. 5 shows an example of the shape of the packaging container having the same configuration as that of Non-Patent Document 1. In the packaging container shown in this figure, five individual containers of the same shape are arranged in a row in the horizontal direction, and a certain amount of chemical solution is sealed in each body. At the time of use, the individual container located at the end is separated, and the pull tab at the tip of the neck is pinched to open the container, and the entire amount of the drug solution is dropped. The plate-shaped handle that extends to the bottom of the individual container can be used as a place to attach various labels, and by pinching the handle at the time of opening or after opening, it is possible to prevent accidental scattering of the chemical solution.

Japanese Unexamined Patent Publication No. 2005-270372 Design Registration No. 1182351

Most eye drops and nasal drops do not use up the entire amount of the drug solution at one time, but after use, the cap is installed and used repeatedly. Therefore, the chemical solution may come into contact with the outside air and various germs may be mixed in, and a preservative is usually added to the chemical solution to prevent its growth. However, depending on the type of chemical solution, it may be difficult to add a preservative. In addition, in order to appeal to users, we may want to clearly indicate that preservatives are not used.

When using a nasal spray container, the nozzle is often directed upward, and the air accumulated in the neck or the like directly under the nozzle cannot be removed in advance. Therefore, at the beginning, only air is sprayed, which gives a feeling of strangeness to the user, presses the button or the side surface of the container more than necessary, and a large amount of chemical solution may be scattered, leading to an unpleasant situation. In particular, such a situation is likely to occur in a simple method in which the side surface of the container is pressed with a finger or the like to increase the internal pressure and spray the chemical solution.

The present invention has been developed based on these circumstances, has a function of spraying various chemicals such as nasal drops, can ensure hygiene of the chemicals without using preservatives, and also allows air to flow from the neck connected to the nozzle. The purpose is to provide a chemical container that can be expelled.

The invention according to claim 1 for solving the above-mentioned problems comprises a main body in which a plurality of individual containers in which a chemical solution is sealed are connected, and a nozzle that is fitted into the separated individual containers and sprays the chemical solution. The individual container is a chemical solution container, and the individual container is composed of a body in which the chemical solution is sealed, a neck portion protruding upward from the body body, and a sealing body closing the tip of the neck portion, and the main body is made of synthetic resin. It is integrally molded as a material, and an outer convex strip having an enlarged outer diameter is formed on the neck portion, and an outer rib protruding outward is formed on the outer peripheral surface of the sealing body. The end side of the nozzle is hollow for fitting the neck portion, and an inward ridge having a narrow inner diameter is formed near the entrance of the hollow portion, and the inner ridge is formed in the axial direction behind the inner ridge. An extending inner rib is formed, and the nozzle is fitted into the neck portion, and the inner convex strip gets over the outer convex strip and is pushed downward thereof, so that the outer convex strip and the inner convex strip are brought into close contact with each other. By preventing leakage of the chemical solution and then twisting the nozzle, the encapsulant is also twisted via the inner rib and the outer rib, the encapsulant is separated from the neck portion , and the chemical solution is sprayed. It is a chemical solution container characterized by being possible.

Similar to Non-Patent Document 1 described above, the chemical solution container according to the present invention has a configuration in which a plurality of individual containers containing the chemical solution are connected, and it is assumed that the chemical solution in the individual containers is used up at one time. Does not seal the inside again. Further, in the present invention, a plurality of consecutive individual containers are referred to as a main body, and a nozzle manufactured separately from the main body is used to have a function of spraying a chemical solution.

The main body is a series of multiple individual containers and is integrally molded using synthetic resin as a material, but the boundary between adjacent individual containers is molded very thinly and can be torn without difficulty. The work of separating the individual container from the main body is extremely easy. In addition, although the number of individual containers can be freely set in one main body, it is generally about 4 to 6 containers.

The nozzle plays a role of spraying the chemical solution enclosed in the individual container, is manufactured separately from the main body, and is fitted into the individual container immediately before use. Inside the nozzle, a narrow path with a narrowed cross section is formed, and a sliver-shaped outlet is formed at the end. When the chemical solution with increased flow velocity reaches the outlet, the chemical solution is diffused. , Pops out like a mist. For hygiene reasons, the nozzles will not be used repeatedly, and the same number as individual containers will be prepared in advance.

The individual container is mainly composed of a body, a neck and a sealing body. Of these, the body is a tubular part that encloses the drug solution, and because the drug solution is pushed out, it has the flexibility to be deformed with a finger or the like. The volume of the body is determined based on the amount of the drug solution dropped. A handle may be provided below the fuselage. The handle is a flat part that is supposed to be pinched by fingers, and the chemical solution does not enter inside it. Therefore, even if the handle is pressed, the chemical solution does not scatter. Furthermore, the handle is flat and can be used for attaching various labels.

The neck is a small-diameter tubular part formed so as to narrow the upper part of the body, and plays a role of sending the chemical solution to the nozzle. In the present invention, since a plurality of individual containers are connected, the individual containers inevitably have an elongated shape, and a neck portion is formed on one end side thereof. The sealing body is located at the tip of the neck and closes the neck, but by fitting the nozzle, the sealing body is opened, some kind of flow path is secured, and the chemical solution can be discharged to the outside.

In order to open the sealing body with the nozzle and secure the flow path of the chemical solution , the sealing body is moved by the nozzle and the sealing body is separated from the neck. However, some kind of sealing measures are required to prevent the chemical solution from leaking from the fitting point between the neck and the nozzle, and measures to prevent the nozzle from being inadvertently detached are also required.

In this way, by using a chemical solution container that can be sprayed with the chemical solution by inserting the nozzle immediately before use and opening the sealant, it is possible to eliminate the opportunity for the chemical solution to come into contact with the outside air, and the total amount of the chemical solution in the individual container at one time. Since it is used up, it is not necessary to add preservatives, and the range of choices for chemicals is widened. When manufacturing the main body, a technology called BFS (simultaneous molding filling) system is generally introduced, and by filling the chemical solution at the same time as molding, the chemical solution does not come into contact with the outside air even at the manufacturing stage, leaving room for germs to mix. It can be completely eliminated.

The invention according to claim 2 assumes a case where the drug solution container is a nasal spray container, and is characterized in that the tip end side of the neck portion extends so as to have an angle with respect to the longitudinal direction of the individual container. Generally, a nasal spray container has its neck turned upward when it is used, but in that posture, air enters the neck and only air is ejected prior to spraying the chemical solution, which may cause discomfort to the user. This situation can be avoided if the air inside is completely pushed out during the manufacture of individual containers. However, in that case, there is a risk that the chemical solution may leak out unexpectedly during use, and usually, clean air is enclosed together with the chemical solution.

In the invention according to claim 2, the neck portion is not projected linearly but is bent in the longitudinal direction of the individual container. As a result, when spraying the drug solution into the nasal cavity, the individual container is tilted sideways and the tip of the nozzle is directed upward, so that the air inside moves to the bottom of the fuselage, the drug solution flows into the neck, and the air is jetted. It is suppressed. Although the bending angle of the neck portion is not limited, about 30 to 60 degrees is suitable with respect to the longitudinal direction of the individual container in consideration of convenience during use and the manufacturing process.

As in the invention according to claim 1, the chemical solution container is composed of a main body and a nozzle, the individual container is separated from the main body immediately before use, the nozzle is fitted into the individual container, and the sealing body located at the tip of the individual container is nozzleed. It is not necessary to consider that the chemical solution comes into contact with the outside air by opening it with a nozzle and spraying the entire amount of the chemical solution at once. Therefore, the addition of preservatives is not required, the range of choices for chemicals is widened, and the appeal to users is improved.

As in the invention of claim 2, in a chemical solution container in which a nasal spray is enclosed, the tip end side of the neck of the individual container is extended so as to have an angle with respect to the longitudinal direction of the individual container, so that it is inevitable during use. The individual container is tilted sideways and the tip of the nozzle is turned upward. Therefore, the air sealed inside the individual container moves to the bottom of the body, the chemical solution flows into the neck, the air injection is suppressed, and the user does not feel uncomfortable.

It is a side view which shows the shape example of the chemical liquid container by this invention, and is the enlarged vertical sectional view of the upper part of an individual container. It is a side view which shows the use state of the individual container drawn in FIG. It is a perspective view showing a detailed structure around the neck, and a state in which a nozzle and an individual container are halved is drawn at the lower part of the figure. It is a perspective view which shows the double type nozzle. It is a perspective view showing a shape example of a packaging container that has been widely used in the past. Five individual containers having the same shape are arranged in a row in the horizontal direction.

FIG. 1 shows an example of the shape of the chemical solution container according to the present invention. This chemical solution container is assumed to be a nasal spray container, and is roughly divided into a main body 11 and a nozzle 31, and the main body 11 has a shape in which four individual containers 12 are connected. Although the main body 11 is integrally molded using polyethylene as a material, the thickness of the boundary portion between the adjacent individual containers 12 is suppressed, and the individual container 12 can be separated from the main body 11 without difficulty. The individual container 12 is composed of a body 14, a handle 15, a neck 16, a sealing body 21, and the like, and the body 14 is a tubular portion in which a chemical solution M is sealed.

The handle 15 is a plate-shaped portion that protrudes downward from the body 14, and the individual container 12 can be handled stably by pinching it with fingers during use. If the body 14 is carelessly pinched by fingers, the chemical solution M may be sprayed at an unexpected timing. Further, since the handle 15 is flat, it can be used as a place for attaching various labels related to the chemical solution M. In addition, the ratio of the lengths of the body 14 and the handle 15 is free, and when the volume of the body 14 is small, the handle 15 is often lengthened in consideration of handling.

The neck portion 16 is a flow path of the chemical solution M formed on the upper part of the body body 14. The upper part of the body 14 has a tapered shape, and a cylindrical neck portion 16 is formed at the tip thereof, and the tip of the neck portion 16 is further closed with a sealing body 21. The sealing body 21 literally plays a role of sealing the inside, but in order to realize spraying of the chemical solution M, the sealing body 21 is shaped so as to be separated from the individual container 12. In addition, two rows of outer ridges 17 having an inflated outer diameter are formed at the tip of the neck portion 16.

The nozzle 31 plays a role of spraying the chemical solution M, is manufactured separately from the main body 11, and is fitted into the individual container 12 by the user prior to spraying. In consideration of convenience at the time of fitting, a brim 33 is formed on the side peripheral surface of the nozzle 31. Further, the end side of the nozzle 31 is hollow, and the neck portion 16 and the sealing body 21 are fitted therein, and the nozzle 31 is integrated with the individual container 12.

An enlarged vertical cross section of the upper part of the individual container 12 is drawn below FIG. At the tip of the neck portion 16, two rows of outer ridges 17 inflated in a bellows shape are formed, and a sealing body 21 is lined up at the tip thereof to seal the inside. The sealing body 21 has a tubular shape with one end closed, but an outer rib 26 is formed on the outer peripheral surface thereof. The outer rib 26 surrounds the side peripheral surface and the end surface of the sealing body 21 and extends in a "U" shape. Further, in order to realize the separation of the sealing body 21, the boundary portion between the outer convex strip 17 and the sealing body 21 is formed thinner than other portions.

The inside of the nozzle 31 is hollow, and an inner ridge 37 having a narrow inner diameter is formed near the inlet thereof. The inner ridge 37 fits into the outer ridge 17, plays a role of fixing the nozzle 31 to the individual container 12, and also prevents leakage of the chemical solution M. Further, the inner rib 36 is a protrusion extending in the axial direction inside the nozzle 31, and the outer rib 26 and the inner rib 36 are brought into contact with each other and the sealing body 21 is twisted to form a boundary between the outer protrusion 17 and the sealing body 21. The part is torn and the individual container 12 is opened.

A narrow path 34 through which the chemical solution M flowing out of the individual container 12 passes is formed on the tip end side of the nozzle 31, and a sliver-shaped outlet 35 is formed at the tip of the narrow path 34. Since the cross section of the narrow road 34 is narrowed down, the flow velocity increases, and then the narrow road 34 reaches the exit 35 to be sprayed forward. A space is secured inside the nozzle 31 so that the separated sealing body 21 can move freely, and the chemical solution M reaches the narrow path 34 without difficulty.

FIG. 2 shows the usage state of the individual container 12 drawn in FIG. After separating the individual container 12 at the end of the main body 11 drawn in FIG. 1, the nozzle 31 is fitted into the sealing body 21 at the tip of the neck 16, and then when the nozzle 31 is twisted, the sealing body 21 also passes through the outer rib 26. Twisting, the sealing body 21 is separated from the individual container 12, and the chemical solution M can be supplied to the nozzle 31. When fitting the nozzle 31, the brim 33 is pushed in so that both of the two rows of outer protrusions 17 enter the inside of the nozzle 31 to prevent liquid leakage.

After fitting the nozzle 31 into the individual container 12, pinch the handle 15 with fingers, lay the individual container 12 sideways and bring it closer to the nose as shown in the lower part of FIG. 2, and direct the nozzle 31 toward the entrance of the nasal cavity. After that, when the body 14 is pressed, the drug solution M is sprayed toward the nasal cavity. At that time, the nozzle 31 is located below the handle 15, and the air in the body 14 moves toward the handle 15. Therefore, the chemical solution M flows into the neck portion 16 and the chemical solution M is sprayed immediately after pressing the body 14. By bending the neck portion 16 in this way, the individual container 12 is laid on its side during use, so that the air in the neck portion 16 can be easily expelled.

FIG. 3 shows a detailed structure around the neck portion 16. The vicinity of the root of the neck portion 16 is bent with respect to the longitudinal direction of the body 14. Further, at the tip of the neck portion 16, two rows of outer ridges 17 having an enlarged outer diameter are formed, and at the tip thereof, a sealing body 21 for sealing the inside of the individual container 12 is formed. The sealing body 21 has a tubular shape with one end closed, the thickness of the boundary portion with the outer convex strip 17 is suppressed, and the outer peripheral surface of the sealing body 21 surrounds the side peripheral surface and the end surface thereof. As described above, the "U" -shaped outer rib 26 is formed. The entire body up to the outer rib 26 is integrally molded, and there are no seams or the like.

At the bottom of FIG. 3, a state in which the nozzle 31 and the individual container 12 are halved is drawn. An annular inner ridge 37 is formed below the inside of the nozzle 31, and when the nozzle 31 is fitted, this is pushed to the lower side of the two rows of outer ridges 17, and the outer ridge 17 and the inner ridge 17 are formed. 37 is in close contact with each other to prevent liquid leakage from the end of the nozzle 31. Further, by arranging the outer protrusions 17 in two rows, the nozzle 31 is stably held with respect to the neck portion 16 and the spray direction is not deviated.

An inner rib 36 extending in the axial direction is formed in the inner part of the nozzle 31. The inner ribs 36 are formed at four positions at equal intervals, come into contact with the outer ribs 26, and play a role of twisting the sealing body 21. Then, when the nozzle 31 is actually fitted and the sealing body 21 is twisted via the inner rib 36 and the outer rib 26, the boundary portion between the outer convex strip 17 and the sealing body 21 is torn and drawn in the lower right of FIG. As described above, the sealing body 21 is separated from the individual container 12, the chemical solution M flows into the nozzle 31, and is sprayed through the narrow path 34 and the outlet 35.

FIG. 4 shows a double nozzle 32. When the present invention is used as a nasal spray container, it may be desired to form a double nozzle, and as shown in the nozzle 32 in this figure, the cylinders 39 are arranged in two rows in a T-shape, and the two outlets 35 are simultaneously arranged. The chemical solution M can also be sprayed. The root portion of the tubular body 39 is integrated by the joint 38, but the inside of the joint 38 has the same structure as the nozzle 31 drawn in FIG. 3 and the like, and the sealing body 21 can be separated from the individual container 12.
