Description

Technical Field

[0001] The present invention relates to an enema container. More specifically, the present invention relates to an enema container that is easy for a user to operate with one hand when self-administering, can stand on its own before and after use, leaves a small amount of residual liquid after use, and does not spontaneously restore its original shape.

Background Art

[0002] Conventionally, enema containers that can stand on their own before and after use have been developed (for example, Patent Document 1). The enema container described in Patent Document 1 can push out the medicinal solution by deforming a part of the main body to push it in during use. Furthermore, from the viewpoint of hygiene, it is desirable for an enema container to be able to stand on its own before and after use.

Summary of the Invention

Problem to be Solved by the Invention

[0004] However, the enema container described in Patent Document 1 leaves a large amount of medicinal solution remaining in the container after use. Therefore, with the enema container described in Patent Document 1, the cost corresponding to the residual medicinal solution increases, and there are cases where a required amount of the medicinal solution cannot be used. Furthermore, in practice, the enema container described in Patent Document 1 cannot be pushed in to the close-contact shape as shown in FIG. 3 of the document. For this reason, after use, the pushed-in portion of the enema container described in Patent Document 1 can return to its original shape. Therefore, when the enema container is left standing on its own after use, there is a risk that the enema container described in Patent Document 1 will tip over due to the movement when returning to its original shape. Furthermore, when a user uses the enema container described in Patent Document 1 for self-administration, the user has to adopt a twisted body posture, making it difficult to operate with one hand.

[0005] This invention has been made in view of the above-mentioned conventional problems, and aims to provide an enema container that is easy for the user to operate with one hand when using it on themselves, can stand on its own before and after use, has a small amount of residual liquid after use, and does not naturally return to its original shape. [Means for solving the problem]

[0006] The present invention, which solves the above problems, mainly includes the following configuration.

[0007] (1) An enema container comprising: a container body having a storage space for filling with liquid medicine and a bottom portion formed at one end for placement on a predetermined surface; and a nozzle portion provided at the end opposite to the one end and having an internal passage that communicates with the storage space, wherein the container body comprises a first main body portion having a nozzle attachment portion to which the nozzle portion is attached, and a second main body portion integrally provided with the first main body portion via a connecting portion and having the bottom portion formed thereon, wherein the cross-sectional area of ​​the container body is formed to increase from the bottom portion toward the connecting portion and decrease from the connecting portion toward the nozzle attachment portion, the second main body portion is a portion that deforms to fold inward of the first main body portion with respect to the connecting portion when the liquid medicine is pushed out, the bottom portion and the nozzle attachment portion are surfaces provided substantially parallel to each other, and the connecting portion is formed in a direction that is inclined with respect to the bottom portion and the nozzle attachment portion.

[0008] With this configuration, the enema container can stand upright on the surface by its base before use, and after use by its connection. Furthermore, the second main body of the enema container can be easily pushed into the first main body without any gaps, using the connection as a boundary. As a result, the enema container has less residual liquid after use, and its shape does not naturally return to its original state. Moreover, the connection of the enema container is formed to be inclined relative to the base and nozzle attachment. Therefore, when using it on oneself, the user can push the second main body into the first main body with one hand, using the corner of the base as the point of force application. In this case, the user's body twisting is reduced, making it easier to operate the enema container in a comfortable posture.

[0009] (2) The enema container according to (1), wherein in a cross section perpendicular to the bottom surface, the length T1 of the periphery of the first main body and the length T2 of the periphery of the second main body satisfy (Equation 1) 0.9 ≤ T1 / T2 ≤ 1.1.

[0010] With this configuration, the length of the periphery of the first main body of the enema container is approximately the same as the length of the periphery of the second main body. Therefore, the enema container can be more easily pushed into the inside of the first main body with less gap, using the connection as the boundary. As a result, less liquid medication remains in the enema container after use.

[0011] (3) The enema container according to (1) or (2), wherein the first main body portion has one or more reinforcing ribs formed thereon that extend from the nozzle mounting portion along the connection portion.

[0012] With this configuration, the enema container makes it easy to push the second main body into the inside of the first main body when using it.

[0013] (4) An enema container according to any one of (1) to (3), wherein reinforcing ribs are formed around the periphery of the connecting portion.

[0014] With this configuration, the enema container is easy to push the second main body into the first main body during use. In addition, the connection part of the enema container is strong, and it has excellent stability when standing upright after use. [Effects of the Invention]

[0015] According to the present invention, it is possible to provide an enema container that is easy for the user to operate with one hand when using it on themselves, can stand upright before and after use, has a small amount of residual liquid after use, and does not naturally return to its original shape.

[0017] <First Embodiment> Fig. 1 is a schematic front view showing a state before use of an enema container 1 according to an embodiment of the present invention. Fig. 2 is a schematic plan view of the enema container 1 according to an embodiment of the present invention. The enema container 1 of the present embodiment comprises: a container body 2 provided with a storage space to be filled with a drug solution, and having a bottom surface portion 21n formed at one end for placing on a predetermined placement surface; and a nozzle portion 3 provided at an end opposite to the one end, and formed with an internal passage communicating with the storage space. The container body 2 comprises: a first body portion 21 formed with a nozzle attachment portion 21m to which the nozzle portion 3 is attached; and a second body portion 22 integrally provided with the first body portion 21 via a connection portion 23, and formed with the bottom surface portion 21n. The cross-sectional area of the container body 2 is formed so as to increase from the bottom surface portion 21n toward the connection portion 23, and decrease from the connection portion 23 toward the nozzle attachment portion 21m. The second body portion 22 is a portion that is deformed so as to be folded inside the first body portion 21 with the connection portion 23 as a reference when the drug solution is pushed out. The bottom surface portion 21n and the nozzle attachment portion 21m are surfaces provided substantially in parallel. The connection portion is formed in a direction inclined with respect to the bottom surface portion and the nozzle attachment portion. Each of these will be described below.

[0018] The container body 2 is provided with a storage space to be filled with a drug solution. The container body 2 comprises a first body portion 21, a second body portion 22, and a connection portion 23 connecting the first body portion 21 and the second body portion 22.

[0019] The drug solution is not particularly limited. To give an example, the drug solution is a drug solution conventionally used for enema applications, and is, for example, glycerin, distilled water, physiological saline, or the like.

[0020] The material constituting the container body 2 is not particularly limited. To give an example, the container body 2 is made of a somewhat flexible resin.

[0021] The method for manufacturing the container body 2 is not particularly limited. For example, the container body 2, including the first main body portion 21, the second main body portion 22, the connecting portion 23, and the nozzle portion 3 described later, can be integrally molded by blow molding or the like. By blow molding or the like, the enema container 1 of this embodiment can be manufactured, which consists of a container body 2 with a storage space inside and a nozzle portion 3 with an internal passage that communicates with the storage space.

[0022] The first main body portion 21 is the part in which a nozzle mounting portion 21m is formed, to which the nozzle portion 3, described later, is attached. The position in the first main body portion 21 to which the nozzle portion 3 is attached is not particularly limited. Typically, the nozzle portion 3 is provided at the center of the nozzle mounting portion 21m, which is the upper surface of the first main body portion 21. In this embodiment, an example is shown in which the nozzle portion 3 is provided at the center of the nozzle mounting portion 21m of the first main body portion 21.

[0023] The second main body portion 22 is a part integrally provided with the first main body portion 21 via a connecting portion 23, and has a bottom surface portion 21n. In its pre-use state, the enema container 1 of this embodiment can stand upright on a predetermined surface via the bottom surface portion 21n.

[0024] The shape of the container body 2 in this embodiment is such that the cross-sectional area of ​​the container body 2 increases from the bottom surface portion 21n toward the connection portion 23, and decreases from the connection portion 23 toward the nozzle mounting portion 21m. In this embodiment, an example is given in which both the first body portion 21 and the second body portion 22 are substantially frustoconical. Of the two bottom surfaces of the first body portion 21, the smaller bottom surface constitutes the nozzle mounting portion 21m, and the larger bottom surface forms the connection portion 23 with the second body portion 22. Similarly, of the two bottom surfaces of the second body portion 22, the smaller bottom surface constitutes the bottom surface portion 21n that is placed on the mounting surface, and the larger bottom surface forms the connection portion 23 with the first body portion 21.

[0025] The connecting portion 23 is formed in a direction that is inclined at an angle θ1 with respect to the bottom portion 21n and the nozzle attachment portion 21m. This allows the user to easily push the second main body portion 22 inward into the first main body portion 21 with the fingers of one hand, using the corner 21c of the bottom portion 21n as the point of force application, instead of pushing the bottom portion 21n of the second main body portion itself inward into the first main body portion 21 with their fingers. In other words, instead of pushing in the direction of arrow A1 shown in Figure 1, the user can easily push the second main body portion 22 inward into the first main body portion 21 by pushing in the direction of arrow A2, using the corner 21c as the point of force application. At that time, the user can grasp the enema container 1 at an angle of θ1 of the connecting portion 23. As a result, the user has less to twist their body when using the enema container 1, making it easier to operate.

[0026] The degree of inclination (angle of inclination θ1) of the connection portion 23 is not particularly limited. For example, the angle of inclination θ1 is preferably 10° or more, and more preferably 20° or more. Also, the angle of inclination θ1 is preferably 60° or less, and more preferably 50° or less. When the angle of inclination θ1 is within the above range, the enema container 1 is easy for the user to operate.

[0027] The nozzle section 3 is a tubular part with an internal passage that communicates with the storage space. One end of the nozzle section 3 is connected to the nozzle attachment section 21m of the container body 2. The other end of the nozzle section 3 is a discharge port from which the liquid chemical is discharged.

[0028] Figure 3 is a schematic cross-sectional view showing the state of the enema container 1 of this embodiment after use. In this embodiment, the cross-section is the plane where the horizontal length of the connecting portion 23 is maximized and perpendicular to the bottom surface portion 21n. That is, as shown in Figure 2, the enema container 1 of this embodiment has a container body 2 that is approximately a regular hexagon in plan view, and a nozzle portion 3 is provided at the center of the nozzle attachment portion 21m. In this case, the cross-section is the plane cut at the position indicated by line AA in Figure 2, passing through the center of the nozzle portion 3 and the position where the horizontal length of the connecting portion 23 is maximized.

[0029] As shown in Figures 1 and 3, the second main body portion 22 is a part that deforms so as to fold inward of the first main body portion 21 with respect to the connecting portion 23 when the liquid medicine is pushed out.

[0030] In the enema container 1 of this embodiment, the bottom surface 21n and the nozzle attachment portion 21m are surfaces that are substantially parallel to each other. Furthermore, in a cross-section perpendicular to the bottom surface 21n (a surface cut at the position indicated by line AA in Figure 2), it is preferable that the length T1 of the periphery of the first main body portion 21 and the length T2 of the periphery of the second main body portion 22 satisfy (Equation 1) 0.9 ≤ T1 / T2 ≤ 1.1. This allows the liquid medicine stored in the storage space to be pushed out by pushing the second main body portion 22 inside the first main body portion 21. As shown in Figure 3, the periphery of the second main body portion 22 is easily deformed to conform to the periphery of the first main body portion 21, and when the second main body portion 22 is pushed inside the first main body portion 21, the volume of the storage space becomes small. Therefore, the liquid medicine is less likely to remain, and almost the entire amount can be used.

[0031] Furthermore, since the periphery of the second main body portion 22 can deform to conform almost seamlessly to the periphery of the first main body portion 21, the enema container 1 after use is less likely to naturally return to its original shape (see Figure 1). Moreover, as shown in Figure 3, when the second main body portion 22 is pushed into the first main body portion 21, the second main body portion 22 folds with respect to the connecting portion 23. As a result, after use, the enema container 1 has a flat connecting portion 23 formed, and by placing this flat portion on a surface, it can stand on its own.

[0032] The T1 / T2 value is preferably 0.9 or higher, more preferably 0.95 or higher, and even more preferably 0.98 or higher. Furthermore, the T1 / T2 value is preferably 1.1 or lower, more preferably 1.05 or lower, and even more preferably 1.02 or lower. When the T1 / T2 value is within the above range, the volume of the storage space is more easily reduced when the second main body 22 is folded inward into the first main body 21. As a result, less of the drug solution remains, and almost the entire amount is easily used. In addition, the entire second main body 22 is easily folded inward into the first main body 21, and a flatter connection part 23 is easily formed. As a result, the enema container 1 has better stability when standing upright after use.

[0033] In this embodiment, it is preferable that the enema container 1 is provided with reinforcing ribs 4 at predetermined locations. The position of the reinforcing ribs 4 is not particularly limited. For example, the position of the reinforcing ribs 4 may be the periphery of the first main body portion 21, the periphery of the second main body portion 22, the connecting portion 23, etc. Referring again to Figures 1 and 2, in this embodiment, the reinforcing ribs 4 are formed on the periphery of the first main body portion 21 (the side edge of the first main body portion 21) so as to extend from the nozzle attachment portion 21m along the connecting portion 23. In addition, the reinforcing ribs 4 are formed along the periphery of the connecting portion 23.

[0034] The number of reinforcing ribs 4 is not particularly limited. For example, the number of reinforcing ribs 4 may be around 1 to 10. In this embodiment, an example is shown in which 6 reinforcing ribs 4 are formed on the first main body portion 21.

[0035] Because reinforcing ribs 4 are formed on the first main body portion 21, the first main body portion 21 is less prone to deformation than the second main body portion 22. As a result, when folding the second main body portion 22 inward into the first main body portion 21 during use, the shape of the first main body portion 21 is less likely to deform, and only the second main body portion 22 is appropriately deformed, making it easier to push out the liquid. In addition, the second main body portion 22 is easily folded inward into the first main body portion 21.

[0036] Furthermore, the reinforcing rib 4 may be formed on the second main body portion 22 instead of the first main body portion 21. When the reinforcing rib is formed on the second main body portion 22, the second main body portion 22 is more likely to maintain its folded shape after being folded inward of the first main body portion 21 during use, and is less likely to return to its original shape naturally. In addition, the reinforcing rib may be provided on both the first main body portion 21 and the second main body portion 22.

[0037] Furthermore, because reinforcing ribs 4 are formed around the periphery of the connecting portion 23, when the second main body portion 22 is folded inward of the first main body portion 21 during use, the shape of the first main body portion 21 is less likely to deform, and only the second main body portion 22 is appropriately deformed, making it easier to push out the liquid. Also, the second main body portion 22 is easily folded inward of the first main body portion 21. Moreover, because reinforcing ribs 4 are formed on the connecting portion 23, the connecting portion 23 is easier to stand upright after use.

[0038] As described above, according to this embodiment, the enema container 1 can stand upright on a surface by its bottom portion 21n before use, and can stand upright on a surface by its connecting portion 23 after use. Furthermore, the enema container 1 is easy to push the second main body portion 22 into the inside of the first main body portion 21 without any gaps, with the connecting portion 23 as the boundary. As a result, the enema container 1 has a small amount of residual liquid medicine after use, and its shape does not naturally return to its original state. Moreover, the connecting portion 23 of the enema container 1 is formed in a direction that is inclined with respect to the bottom portion 21n and the nozzle attachment portion 21m. Therefore, when the user uses it on themselves, they can push it in with one hand, for example, using the corner 21c of the bottom portion 21n of the second main body portion 22 as the point of force application. In this case, the degree to which the user has to twist their body during use is reduced, making it easier to operate the enema container 1.

[0039] <Second Embodiment> Figure 4 is a schematic front view showing the state of the enema container 1a of one embodiment of the present invention before use. Figure 5 is a schematic top view of the enema container 1a of one embodiment of the present invention. The enema container 1a of this embodiment is the same as the enema container 1 described above in relation to the first embodiment (see Figures 1 to 3), except that the shape of the container body 2a is different. Therefore, in the following, explanations of redundant components will be omitted as appropriate.

[0040] As shown in Figure 4, in this embodiment, both the first main body portion 21a and the second main body portion 22a are substantially frustoconical in shape, with a somewhat rounded periphery. Of the two bottom surfaces of the first main body portion 21a, the smaller bottom surface constitutes the nozzle mounting portion 21m, and the larger bottom surface forms the connection portion 23 with the second main body portion 22a. Similarly, of the two bottom surfaces of the second main body portion 22a, the smaller bottom surface constitutes the bottom surface portion 21n that is placed on the mounting surface, and the larger bottom surface forms the connection portion 23 with the first main body portion 21a.

[0041] In the enema container 1a of this embodiment, when the second main body portion 22a is folded inward of the first main body portion 21a using the corner 21c as the point of force application during use, the periphery of the second main body portion 22a is rounded, making it easier to deform to conform to the similarly rounded periphery of the first main body portion 21a. As a result, the amount of residual liquid in the enema container 1a can be reduced.

[0042] <Third Embodiment> Figure 6 is a schematic front view showing the state of the enema container 1b of one embodiment of the present invention before use. Figure 7 is a schematic top view of the enema container 1b of one embodiment of the present invention. The enema container 1b of this embodiment is the same as the enema container 1 described above in relation to the first embodiment (see Figures 1 to 3), except that the shape of the container body 2b is different. Therefore, in the following, explanations of redundant components will be omitted as appropriate.

[0043] As shown in Figures 6 and 7, in this embodiment, both the first main body portion 21b and the second main body portion 22b are substantially in the shape of a truncated square pyramid.

[0044] In this embodiment, when the second main body portion 22b of the enema container 1b is folded inward into the first main body portion 21b during use, the folded second main body portion 22b is more likely to maintain its folded shape compared to the enema container 1 described above in relation to the first embodiment (see Figures 1 to 3). As a result, the shape of the enema container 1b is less likely to naturally return to its original state after use and is more stable. [Explanation of symbols]
