Description

Technical Field

[0001] The present invention relates to a mouthpiece component for discharging the contents stored in a storage bag, a medical component, and a storage bag provided with such a component. Further, it relates to a mouthpiece component for discharging excreta, excreted fluid, gas, exudate, secretion, etc. (hereinafter, these are collectively referred to as "excreta". The same shall apply hereinafter) from inside or on the surface of a living body, a medical component, a storage bag provided with such a component, an excreta storage bag, and the like.

Background Art

[0002] When a person cannot control the excretion of feces or urine by their own will, or when there is a disease in the digestive or urinary organs, a surgical operation may be performed to guide the intestinal or urinary tract to the body surface and a stoma is created on the body surface. A person with a stoma needs to wear a storage bag such as a pouch that can temporarily store excreta from the stoma. In the case of a person with a urinary stoma, a leg bag may also be used to increase the urine storage volume. In addition, people with other diseases who have an opening or wound on the body surface also need to wear a storage bag around the opening or wound in order to process the excreta discharged by drainage or the like.

[0003] The storage bags such as pouches and leg bags are equipped with a mouthpiece component which is a medical component, and the excreta accumulated in the excreta storage bag is discharged to the outside using this mouthpiece component. As this mouthpiece component, a cap-type valve that closes or opens the discharge of excreta by inserting and removing an insertion cap portion into a tubular discharge port, and a rotary valve that closes or opens the discharge of excreta with a rotary cock valve provided at the discharge port are mainly used.

[0004] As a cap-type mouthpiece component, for example, in FIGS. 2 and 3 of Patent Document 1, a closure 140 can be removably coupled to an outlet body 120 by frictional engagement with the outlet body 120 at an outlet opening 122, and the frictional engagement between the plug 140 and the inner surface 131 is a sealing engagement that substantially suppresses or restricts an unintended outflow of the contents passing through the outlet opening 122. A mouthpiece component is disclosed.

[0005] As an example of a rotary mouthpiece component, Figure 1 of Patent Document 2 discloses a mouthpiece component comprising a valve body capable of sealing to the associated container and a stem attached to the valve body having a portion that communicates with a fluid storage area, wherein the valve is moved between an open position and a closed position by rotating the stem in the gripping area.

[0015] 1. Background and Overview of the Invention

[0016] When discharging contents from a storage bag equipped with a spout, it is desirable for the user to remove the cap from the sealing part at the tip of the spout and discharge the contents to the intended disposal or collection point while minimizing scattering of the contents from the opened sealing part. At this time, it may be necessary to adjust the flow of the contents by holding the spout from the outside (e.g., allowing or blocking the flow, suppressing the flow, controlling the flow rate, etc.). For example, if the user can effectively suppress the flow of the contents, or switch between allowing and blocking the flow of the contents effectively, scattering of the contents during discharge can be reduced. However, skillfully adjusting the flow of the contents often depends on the individual skill and physical ability of the user.

[0017] Therefore, the main objective of the present invention is to provide a spout component that facilitates the discharge operation of contents from a storage bag, particularly the suppression of the discharge flow, and a storage bag equipped with said spout component. The contents may also be a fluid liquid.

[0018] In particular, when the contents are excrement, it is desirable from a hygienic standpoint to prevent the excrement from scattering as much as possible from the tip of the outlet of the mouthpiece component. That is, the main objective of the present invention may be to provide a mouthpiece component that facilitates the discharge operation of excrement from an excrement container, in particular the suppression of the discharge flow, and an excrement container equipped with said mouthpiece component.

[0019] As shown in the comparative examples in the [Examples] section described later and in Figure 11, in the case of conventional cap-type mouthpiece components, when the cap is pulled out from the sealing part to open the flow of contents, and at the same time the outer sides of the front and back of the mouthpiece component are pressed with fingers such as the thumb and index finger to compress the hollow flow path, the inner wall of the part pressed by the fingers can be tightly sealed, but the inner walls at both ends in the longitudinal direction do not bend and cannot be tightly sealed, resulting in horizontally elongated, roughly elliptical gaps at both ends. With conventional cap-type mouthpiece components, gaps are created at both ends in the longitudinal direction when force is applied with fingers, making it difficult to suppress the flow of contents, especially to block the flow.

[0020] Therefore, after diligent study, the inventors discovered that by providing a bent portion in the mouthpiece component, the inner wall can be sealed when pressure is applied with a finger or the like by this bent portion. Specifically, the inventors discovered that by making the thickness of the area in the mouthpiece component that is difficult to seal with pressure such as finger pressure relatively thinner, this area can be made into a bent portion. Examples of such bent portions include providing one or more notches in the inner wall of the mouthpiece component, and providing one or more pressing portions that are built up and protrude from the outer wall of the mouthpiece component. Furthermore, a suitable location for the bent portion is the area between the attachment portion, which can be connected to the bag portion (the pouch seal portion), and the sealing portion, which seals the flow path with a cap portion or the like. By providing the bent portion in this area, the risk of damage to the bag portion is reduced by avoiding force being applied to the attachment portion, sealing performance is ensured by avoiding installation or force being applied to the sealing portion, and discharge control work can be easily performed. In addition, to further improve the function of the bent portion in this area, a pressing portion can be provided for applying force, and this pressing portion may also function as an indicator. Providing such a pressing portion makes it easier to improve the airtightness of the inner wall. For example, providing a pressing portion makes it easier to recognize the position to press with a finger and makes it easier to apply pressure in a surface area. This leads to avoiding damage to the bag portion and improving airtightness by efficiently applying force to the bent portion.

[0021] As a result of further investigation, the inventors have found that the flexible cylindrical portion of the mouthpiece component is provided with two flow-suppressing bends positioned approximately opposite each other on its circumference, which serve as the starting points for deformation when an external force is applied. By applying force from the outside to the inside on both sides of this flexible cylindrical portion, the gap that occurred at both ends of the hollow flow path when force was applied with a finger in conventional cap-type mouthpiece components can be significantly reduced, and the inner walls at both ends can be made to adhere tightly. In other words, the inventors have been able to adopt a configuration in which the inner walls adhere tightly when force is applied with a finger, crushing the hollow flow path and suppressing the flow rate discharge. As a result, the inventors have also found that the operation of discharging the contents from the storage bag, especially suppressing discharge, can be made easier, and thus the present invention has been completed. Furthermore, by having an additional flow-suppressing bend on approximately the same circumference as the two flow-suppressing bends, the suppression of contents discharge can be made even easier. Furthermore, the two spill-suppressing bends are provided on the inner wall of the flexible cylindrical section and have notches that open inward, making it easier to suppress the discharge of the contents. Furthermore, the cross-sectional shape of the flexible cylindrical section, which is perpendicular to the flow path direction, is approximately elliptical, which makes it easier to suppress the discharge of contents.

[0022] Based on the above, this technology is It is a mouthpiece component that is attached to the bag portion that contains the contents. A flexible cylindrical portion having a hollow channel through which the contents flow, An attachment portion is provided at one end of the aforementioned flexible cylindrical portion and is connectable to the aforementioned bag portion, A sealing portion is provided at the other end of the flexible cylindrical portion and seals the hollow flow path, Equipped with, The aforementioned flexible cylindrical portion has two flow-suppressing bends positioned substantially opposite each other on its circumference, which serve as the starting points for deformation when an external force is applied, thus providing a mouthpiece component. Furthermore, this technology can provide a storage bag having the aforementioned mouthpiece component.

[0023] Furthermore, in a preferred embodiment, it is preferable to have an additional flow-suppressing bend located on substantially the same circumference as the two flow-suppressing bends. Furthermore, in a preferred embodiment, the two flow-suppressing bends are preferably provided on the inner wall of the flexible cylindrical portion and have notches that open inward. Furthermore, in a preferred embodiment, the cross-sectional shape of the flexible cylindrical portion perpendicular to the flow direction is preferably approximately elliptical. Furthermore, in a preferred embodiment, the flexible cylindrical portion is preferably provided with a pressing portion on its outer wall that is visible and / or tactilely recognizable. Furthermore, in a preferred embodiment, the contents are preferably excrement.

[0024] 2. Mouthpiece parts according to this embodiment

[0025] An example of the configuration of a medical component according to one embodiment of the present invention will be described with reference to Figures 1 to 12, but the present invention is not particularly limited to the configuration and description of one embodiment, these drawings and reference numerals.

[0026] The mouthpiece component 1 according to this embodiment is preferably a mouthpiece component that is attached to a bag portion 101 that contains contents (see Figures 1 and 12, etc.). The mouthpiece component 1 preferably comprises a flexible cylindrical portion 30 having a hollow channel 5 through which the contents flow, an attachment portion 20 provided at one end of the flexible cylindrical portion 30 and connectable to the bag portion 101, and a sealing portion 40 provided at the other end of the flexible cylindrical portion 30 and sealing the hollow channel 5 (see Figures 1, 2, 5, 6, etc.). Furthermore, the mouthpiece component 1 preferably has two flow-suppressing bends 10, 10 on the flexible cylindrical portion 30 that are positioned substantially opposite each other on the circumference, and these two flow-suppressing bends 10, 10 are preferably configured to be the starting points of deformation when an external force is applied (see Figures 2, 4, 6, 10, etc.). By adjusting the external force applied to the mouthpiece component, such as applying or not applying an external force, the outflow-suppressing bends 10, 10 provided on the inner wall function as starting points for deformation, making it easy to discharge the contents flowing from the storage bag 101. In particular, the two outflow-suppressing bends 10, 10, which are positioned approximately opposite each other on the circumference and function as starting points for deformation when an external force is applied, make it easy to suppress discharge. Preferably, the external force is applied from a direction approximately perpendicular to the straight line between the two outflow-suppressing bends 10, 10. Furthermore, preferably, the external force is applied from the outside along the central axis (e.g., the Y-axis direction, front and back). The location of the external force is not particularly limited, but examples include the flexible cylindrical portion 30, the vicinity of the sealing portion 40 in the flexible cylindrical portion 30 (e.g., the lower half of the flexible cylindrical portion), and the connection portion between the flexible cylindrical portion and the sealing portion 40.

[0027] The mouthpiece component 1 is preferably flexible and preferably made of flexible resin. The bag portion 101 is not particularly limited, but may be, for example, a waste collection bag. Examples of waste collection bags are not particularly limited, but include pouches for collecting waste from a stoma and leg bags. One or more of these may be selected.

[0028] As shown in Figures 1, 2, and 6, the mouthpiece component 1 preferably has a hollow channel 5 on its inside from which the contents can be discharged. The contents flowing from the bag portion 101 into the mouthpiece component 1 pass sequentially through the hollow channel 5 of the attachment portion 20, the hollow channel 5 of the flexible cylindrical portion 30, and the hollow channel 5 of the sealing portion 40, and can be discharged to the outside from the discharge port at the end of the sealing portion. In this embodiment, the contents may be replaced with a fluid (preferably a liquid), and it is more preferable that the contents are low viscosity, such as those intended for discharge operations in an ileostomy appliance. The direction of the channel may be said to be the direction of the hollow channel or the Z-axis direction. In addition, the substantially horizontal direction in this embodiment may be a direction perpendicular to the direction of the channel, and may be said to be the X-axis and / or Y-axis direction. Furthermore, the direction toward the outside from the central axis may be said to be the outward direction, and the direction toward the central axis may be said to be the inward direction, and it is preferable that these outward and inward directions are related on a line perpendicular to the central axis.

[0029] The mouthpiece component 1 is preferably hollow and substantially cylindrical in shape. The total length in the flow path direction (Z-axis direction) is not particularly limited, but can be equal to or longer than the length in the direction perpendicular to the flow path direction. The external shape of the mouthpiece component 1 is not particularly limited and may consist of the external shapes of the mounting portion 20, the flexible cylindrical portion 30, and the sealing portion 30. It is more preferable that the mouthpiece component 1 has a hollow flow path 5 inside the substantially cylindrical shape through which contents (e.g., stoma-derived excrement) flow. The three-dimensional shape of the hollow flow path is not particularly limited, but can be substantially cylindrical, substantially elliptical, tapered, or a shape with a taper added to these substantially cylindrical shapes (e.g., inverted substantially elliptical frustum, inverted substantially elliptical frustum). The "approximately elliptical" in substantially elliptical prism and inverted substantially elliptical frustum can be appropriately represented by the "approximately elliptical" configuration described later. Furthermore, the cross-sectional shape of the hollow channel along the flow direction is not particularly limited, but examples include quadrilateral shapes (rectangular, trapezoidal, etc.), tapered shapes (inverted triangular, inverted trapezoidal, tapered shape with a curved surface, etc.), and combinations thereof. One or more of these shapes can be selected.

[0030] The mouthpiece component 1 preferably comprises a mounting portion 20, a flexible cylindrical portion 30, and a sealing portion 40, and more preferably arranged in the order of mounting portion 20, flexible cylindrical portion 30, and sealing portion 40 from top to bottom. The mounting portion 20, flexible cylindrical portion 30, and sealing portion 40 of the mouthpiece component 1 may each have substantially the same or different external shapes or hollow flow channel shapes. Furthermore, the mouthpiece component 1 is preferably composed of the mounting portion 20, flexible cylindrical portion 30, and sealing portion 40 and integrally molded, and more preferably these parts are molded from the same resin material (for example, a flexible resin raw material).

[0031] The external shapes of the mounting portion 20, the flexible portion 30, and the sealing portion 40 are not particularly limited. For example, the cross-sectional shape perpendicular to the flow path direction may be a roughly perfect circle, a roughly ellipse, a roughly square (rectangle, square, rhombus, etc.), and it is preferable that the shape is easy to apply force from the outside and / or is easy to see. One or more types selected from a roughly ellipse, a roughly rounded rectangle, and a roughly elongated rhombus are preferred. The three-dimensional shape of the hollow flow path of the mounting portion 20, the flexible portion 30, and the sealing portion 40 is configured to allow the contents to flow easily from the bag portion 101 to the outlet. For example, the shape may be a roughly cylindrical shape, a tapered shape, or a horizontally or vertically elongated semi-ellipsoidal shape with a hollow flow path.

[0032] As a preferred example of the mouthpiece component 1, the arrangement and internal shape of the mounting portion 20, the flexible portion 30, and the sealing portion 40 are shown in Figures 2A and 3A-C.

[0033] Figure 3A shows a cross-sectional view and internal shape of the mounting portion 20 and its hollow flow path from the cutting line a onwards, as viewed from above, with the upper end surface of the mounting portion 20 being the cutting line a. The cross-sectional view along the cutting line a in Figure 3A is a hollow, horizontally elongated, roughly elliptical shape (the minor axis is in the Y-axis direction and the major axis is in the X-axis direction), and the hollow flow path 5 within the mounting portion is tapered toward the outlet.

[0034] Figure 3B shows the cross-sectional shape and internal shape of the hollow flow path of the flexible cylindrical section 30 after the line b, when the flexible cylindrical section 30 is cut along the line b, and viewed from above. The cross-sectional view after the line b in Figure 3B is a hollow, horizontally elongated, roughly elliptical shape (the minor axis is in the Y-axis direction and the major axis is in the X-axis direction). In addition, the inner wall of the flexible cylindrical section 30 is provided with the flow-restricting bends 10, 10 at both ends in the direction of the major axis.

[0035] Figure 3C shows a cross-sectional view and internal shape of the sealing portion 40 and its hollow channel from the upper end surface of the sealing portion 40, with the upper end surface of the sealing portion 40 being the cutting line c, as viewed from above. The cross-sectional view from the cutting line c in Figure 3C is a hollow, horizontally elongated, approximately elliptical shape, and a hollow channel 5 is provided that can be fitted with a horizontally elongated, approximately elliptical cap portion 50. The outer wall and hollow channel, as viewed from the front or back, are preferably approximately rectangular in shape.

[0036] Figure 8 shows the mouthpiece component 1 as viewed from the outlet of the sealing portion 40. Figure 8 shows the mouthpiece component 1, which is configured such that the outer wall increases in the order of sealing portion 40, flexible cylindrical portion 30, and mounting portion 20. Each of these parts is a hollow, horizontally elongated, roughly elliptical shape, and each has a different outer circumference.

[0037] As an example of the external shape of the mouthpiece component 1, for example, the mounting portion 20 and the flexible cylindrical portion 30 have an integrated external shape, and this integrated external shape may be, for example, a hollow semi-ellipsoid (for example, a horizontally elongated semi-ellipsoid). The integrated external shape of the mounting portion 20 and the flexible cylindrical portion 30 is tapered when viewed from the front and approximately rectangular when viewed from the side, and the approximately horizontal cross-sectional shape of these integrated hollow flow channels may be approximately elliptical. In this case, the external shape of the sealing portion 40 may be, for example, approximately cylindrical (for example, approximately elliptical). The external shape of the sealing portion 40 is approximately rectangular when viewed from the front, back, or side, and the hollow flow channel in the sealing portion is approximately cylindrical, and the approximately horizontal cross-sectional shape may be approximately elliptical. The mouthpiece component 1 may be a combination of these mounting portion 20, flexible cylindrical portion 30, and sealing portion 40.

[0038] The flexible cylindrical portion 30 preferably has at least two flow-suppressing bends 10, 10 positioned substantially opposite each other on its circumference (see, for example, Figures 4 and 6). In addition to the two flow-suppressing bends 10, 10, the flexible cylindrical portion 30 preferably has further flow-suppressing bends on substantially the same circumference as the two flow-suppressing bends 10, 10.

[0039] The flow-suppressing bends used in the present invention (for example, the first, second, and third bends) are preferably configured to be the starting points for deformation when an external force is applied. It is more preferable that the two flow-suppressing bends 10, 10 are arranged on a line passing through the central axis. In this embodiment, it is preferable to provide two outflow-suppressing bends 10, 10 on the inner wall of the hollow flow path side of the flexible cylindrical portion 30, and the bends are preferably notched in shape so as to open inward (see, for example, Figures 4 and 6). The substantially horizontal cross-sectional shape of the flexible cylindrical portion 30 is not particularly limited, and examples include a hollow substantially circular shape (for example, a hollow substantially perfect circle, a hollow substantially elliptical shape), and a hollow shape with a longitudinal direction (long axis direction) and a short axis direction (short axis direction) (for example, a hollow horizontally elongated substantially elliptical shape, a hollow substantially rectangular shape with rounded corners, etc.) makes it easier to make the entire inner wall adhere when force is applied, and thus easier to suppress or prevent discharge.

[0040] The two flow-suppressing bends 10, 10 in the flexible cylindrical section 30 become the starting points for deformation when an external force is applied. Then, as shown in Figures 10A and 10B, when force is applied from the outside of the flexible cylindrical section 30, such as by finger pressure, the opposing inner walls of the applied portion come into contact with each other, and an outward force is generated on each of the bends 10, 10. This allows the inner walls of the first flow-suppressing bends 10, 10 to come into close proximity or contact. In this way, the opposing inner walls come into contact with each other, and the gaps between the inner walls at both ends can be greatly reduced. As a result, the opposing inner walls can come into contact from one bend 10 to the other. This contact state at both ends allows the function of suppressing the flow of contents in the hollow channel to be exerted. In this way, discharge suppression can be easily achieved, and discharge from the storage bag can also be easily performed.

[0041] In this embodiment, it is preferable that the flexible cylindrical portion 30 is provided with a pressing area 35 on its outer wall, which suppresses or blocks the flow of contents by pressing the internal flow path from the outside with a finger or the like. This pressing area may be provided anywhere on the outer wall of the flexible cylindrical portion 30 (for example, in Figures 1, 2, 4A, and 4B). The pressing area 35 may also be a pressing portion 35.

[0042] The flexible cylindrical portion 30 is preferably provided with a press portion 35 that is visible and / or tactilely recognizable, and such recognizable press portion 35 may also be used as an indicator (see Figures 2A, 4C and 7, etc.). The number of press portions 35 may be one or more, and in the case of multiple portions, they may be provided in two or four locations, such as the front and back and both sides, but two locations, the front and back, are preferred, and it is also preferable that the press portions 35 be provided in two locations, the proximal surface and the distal surface, when the bag portion is attached to the user. The pressing portion 35 is preferably located slightly below the mounting portion 20 in the Z-axis direction, assuming the overall height of the flexible cylindrical portion 30 in the flow direction is 100, the boundary with the mounting portion 20 is 0, and the boundary with the sealing portion 30 is 100, so as not to damage the bag portion. Examples include 5, 6, 7, 8, 9, or 10 to 100. The pressing area may also be set within this preferred range.

[0043] The pressing portion 35 is preferably provided on the outer wall of the flexible cylindrical portion, and preferably on the outer wall other than the area where the flow-suppressing bends 10, 10 are provided. The pressing portion 35 is preferably provided on the outer wall in a direction substantially perpendicular to the straight line between the flow-suppressing bends 10, 10, and it is more preferable that this "direction substantially perpendicular to the straight line" passes through the central axis. When the pressing portion 35 is viewed from the front, the pressing portion 35 in the X-axis direction is preferably within the range of 5 to 95, more preferably within the range of 10 to 90, with the left and right widths set to 100, and the left side set to 0 and the right side set to 100, as this facilitates the application of force such as acupressure. The pressing area may be set within this preferred range.

[0044] The shape of the pressing portion 35 is not particularly limited, but is preferably a shape that allows for visual and / or tactile recognition, for example, it may be a planar shape or a three-dimensional shape. Visual recognition is not particularly limited, but examples include colors, signs, displays (letters, symbols), patterns (straight lines, curves, combinations thereof, etc.) and sealing or labeling materials thereof. For tactile recognition, it is preferably a three-dimensional shape that can be recognized by the finger, for example, patterns, straight lines, curves, concave and convex shapes, rough and smooth surfaces, three-dimensional shapes, polyhedral shapes, and teardrop shapes. One or more of these can be selected.

[0045] When the pressing part 35 functions as an indicator, the user can easily understand the location or indication of the pressure point, and / or the location or indication of the spill-suppression bending parts 10, 10. By applying pressure to this indicator, force is efficiently applied to the spill-suppression bending parts 10, 10, efficiently crushing the center and both ends of the hollow flow path and making the inner wall tightly sealed laterally, thereby making spill suppression easier. The indicator function of the pressing part allows, for example, the recognition of the position of the pouch seal and the attachment part of the mouthpiece component. More specifically, it becomes possible to grasp the position of the pouch seal to reduce the risk of damage to the pouch or bag, and to ensure sealing by the mouthpiece component. Furthermore, the pressing part can be recognized as an indicator that spill suppression by applying pressure is easy, and more specifically, it makes it easier to recognize the position to press with a finger, and makes it easier to apply pressure to a surface.

[0046] To explain the operation and function of the mouthpiece component with a more specific example, as shown in Figure 10A, by applying force from both sides, with the tip of the thumb on the front pressing part and the side of the index finger on the back pressing part, the inner wall of the pressing area is crushed from both pressing parts, and force is also applied to the flow-suppressing bends 10, 10 in the longitudinal direction, causing the inner walls of these bends 10, 10 to be in close contact or close proximity. As shown in Figure 10B, the force applied from the outside toward the central axis causes a part of the inner wall of the flexible cylindrical part 30 to be in close contact or close proximity along the longitudinal direction, thereby blocking or closing the flow of contents, and preventing or suppressing the flow of contents flowing from the attachment part. As a result, the inflow of contents into the sealing part is eliminated or greatly reduced, making it easy to suppress discharge and also easy to discharge from the storage bag.

[0047] As an example of the pressing portion 35, for instance, in the case shown in Figure 2A, the outer wall in the region between the b-cutting line and the c-cutting line may be colored to form the pressing portion, or a lateral groove recognizable by a finger may be provided to form the pressing portion. Alternatively, as shown in Figure 7, the pressing portion may be provided in a portion of the outer wall, and the thickness of the pressing portion (thickness protruding from the outer wall) may be thin or thick. In cases where the function of a bending portion is to be performed, it is desirable to increase the thickness as shown in Figure 4C.

[0048] As an indicator of the pressing part 35, the user can easily understand the location or indication of the area where force is applied, and / or the location or indication of the spillage suppression bends 10, 10. By applying force to this indicator, the hollow flow path can be crushed, making spillage suppression easier. The indicator function of the pressing part allows, for example, the recognition of the position of the pouch seal part and the mounting part of the mouthpiece component. More specifically, it becomes possible to grasp the position of the pouch seal part to reduce the risk of pouch damage and to ensure sealing by the mouthpiece component. Furthermore, the pressing part can be recognized as an indicator that spillage suppression by applying force is easy, and more specifically, it makes it easier to recognize the position to press with a finger, and makes it easier to apply pressure to a surface.

[0049] In a preferred embodiment of this design, the cross-sectional shape of the flexible cylindrical portion 30 in the substantially horizontal direction is preferably a horizontally elongated, substantially elliptical shape, and it is preferable that it has at least two outflow-suppressing bends 10, 10 positioned substantially opposite each other on the circumference at both ends of the inner wall in the direction of the major axis. Furthermore, it is preferable that the two outflow-suppressing bends 10, 10 are positioned substantially opposite each other on the circumference in the direction of the major axis of the horizontally elongated, substantially elliptical shape, and it is even more preferable that they are positioned on the major axis passing through the central axis. In the horizontally elongated, substantially elliptical flexible cylindrical portion 30, when an external force is applied from the outside in the direction of the minor axis, the two outflow-suppressing bends 10, 10 become the starting points of deformation. When a force is applied from the direction of the minor axis of the flexible cylindrical portion 30, this force is directed outwards on both sides in the direction of the major axis, thereby bringing the inner walls of the first outflow-suppressing bends 10, 10 closer together or into contact. The force applied from both the front and back outer walls causes the inner walls of the pressing area 35 (or pressing portion 35) to come into contact with each other, and the gaps that form in the inner walls at both ends can be significantly reduced. As a result, discharge can be easily suppressed, and the discharge operation from the storage bag can also be easily performed.

[0050] The two outflow-suppressing bends 10, 10 are also referred to as the first outflow-suppressing bends 10, 10. In order to distinguish the first outflow-suppressing bend from the other outflow-suppressing bends, these other bends may be conveniently numbered as the second, third, ..., but the technical scope of this embodiment will not be narrowed by the numbering of the bends.

[0051] The three-dimensional shape of the outflow-restricting bend 10 (preferably a notch) provided on the inner wall of the hollow flow channel side of the flexible cylindrical portion 30 is not particularly limited, but it is preferably a space formed inside the inner wall. Furthermore, it is more preferable that the outflow-restricting bend 10 is a space that protrudes outward from the circumference of the inner wall and / or is a space that opens inward. Examples of the three-dimensional shape of the outflow-restricting bend include, but are not limited to, a roughly triangular shape or a roughly trapezoidal shape. In this context, "circumference" refers to the approximately horizontal cross-sectional shape of the mouthpiece component 10, specifically the area around the inner wall on the hollow flow channel side, and is defined by a line that defines the perimeter of a polygon or curved shape on a surface, and is not particularly limited to a circle.

[0052] Furthermore, the substantially horizontal cross-sectional shape of the outflow-restricting bent portion 10 provided on the inner wall of the hollow flow channel side of the flexible cylindrical portion 30 is not particularly limited, and examples include notched shapes such as V-shape, trapezoidal (inverted V-shape), and U-shape. One or more of these can be selected.

[0053] The notch shape may be provided as a notch portion, and it is preferable that it widens in the direction of the flow path in a reverse taper manner. Of these, a V-shape is preferred from the viewpoint of reducing the gaps that occur in the inner walls of both ends in the longitudinal direction when force is applied.

[0054] The three-dimensional shape of the notch is not particularly limited, but is preferably one or more combinations selected from, for example, a roughly triangular prism shape or a roughly triangular pyramidal shape. As shown in Figure 6, for example, a combination shape in which a roughly triangular pyramidal shape is placed below a roughly triangular shape is an example. Furthermore, the cross-sectional shape of the notch in the approximately horizontal direction is preferably a roughly triangular shape with the tip facing outward and opening inward. The cross-sectional shape of the flow-suppressing bend 10 in the approximately vertical direction may be an inverted triangle or a tapered shape to facilitate the movement of the contents to the discharge port. As shown in Figure 6, the notch may be formed such that the upper depth (D) of the flow-suppressing bend 10 is deeper than the lower depth (D), and an incline is provided to allow flow toward the discharge port.

[0055] Furthermore, as shown in Figures 3B and 6, the "depth (D)" of the outflow-suppressing bend portion 10 (preferably a notch) in the substantially horizontal direction (e.g., the X-axis direction) is the distance (length) from the tip protruding from the circumference in the substantially horizontal direction (e.g., the X-axis direction) to the circumference of the inner wall (if the bend portion 10 is not provided), and it is preferable that this distance is the shortest possible distance. More preferably, the "depth (D)" may be the distance from the circumference of the inner wall of the sealing portion 40 to the tip of the protruding notch shape, as shown in Figure 6. Note that if the substantially horizontal cross-section is longer in the X-axis direction than in the Y-axis direction, the "depth (D)" is preferably the length in the X-axis direction.

[0056] The tip position of the "depth (D)" in the outflow-suppressing bent portion 10 is preferably beyond the inner circumference of the sealing portion 40 in the outward direction, and / or is preferably approximately equal to the inner circumference of the mounting portion 20 or not exceeding the inner circumference of the mounting portion 20 in the outward direction. In this case, the length of the inner circumference of the sealing portion 40 is more preferably the major axis or maximum length in the approximately horizontal direction of the hollow flow path in the sealing portion region. Also, in this case, the inner circumference of the mounting portion 20 is more preferably the major axis or maximum length in the approximately horizontal direction of the hollow flow path in the mounting portion region.

[0057] Furthermore, the "angle at the tip (α°)" of the notched shape protruding from the circumference is the angle of the interior angle formed by the two sides of the notched shape, as shown in Figure 3B.

[0058] Furthermore, as shown in Figures 3B and 6, the "width (W)" of the outflow-suppressing bend 10 (preferably a notch) in the substantially horizontal direction (for example, the Y-axis direction) is the length along the straight line between two points where the outflow-suppressing bend 10 touches the circumference when the bend 10 is provided on the circumference, and is, for example, the length in the Y-axis direction (length along the straight line). In addition, if the substantially horizontal cross-sectional shape is elongated in the X-axis direction, the "width (W)" is preferably the length in the Y-axis direction.

[0059] The "height (H)" of the outflow-suppressing bend 10 (preferably a notch) is not particularly limited and, as shown in Figure 6, is the length of the outflow-suppressing bend formed on the inner wall in the flow direction (for example, the Z-axis direction), and is the distance between the upper end and the lower end of the outflow-suppressing bend 10.

[0060] The length of the "depth (D)" in the outflow-suppressing bent portion 10 is not particularly limited, but a suitable upper limit is preferably 25 mm or less, more preferably 20 mm or less, and even more preferably 10 mm or less, and a suitable lower limit is preferably 0.1 mm or more, more preferably 0.5 mm or more, and even more preferably 1.0 mm or more.

[0061] The angle of "angle (α°)" in the outflow suppression bend 10 is not particularly limited, but it is preferably acute. More specifically, a suitable upper limit is preferably 100 degrees or less, more preferably 90 degrees or less, and even more preferably 80 degrees or less. A suitable lower limit is preferably 10 degrees or more, more preferably 20 degrees or more, even more preferably 30 degrees or more, more preferably 40 degrees or more, more preferably 50 degrees or more, more preferably 60 degrees or more, and even more preferably 70 degrees or more.

[0062] The length of the "width (W)" in the outflow-suppressing bent portion 10 is not particularly limited, but a suitable upper limit is preferably 20 mm or less, more preferably 15 mm or less, and even more preferably 5.0 mm or less, and a suitable lower limit is preferably 0.1 mm or more, more preferably 0.5 mm or more, and even more preferably 1.0 mm or more.

[0063] Furthermore, the length of the "height (H)" in the outflow-suppressing bent portion 10 is not particularly limited, but a suitable upper limit is preferably 60 mm or less, more preferably 50 mm or less, even more preferably 25 mm or less, and even more preferably 8.5 mm or less, and a suitable lower limit is preferably 0.1 mm or more, more preferably 0.5 mm or more, and even more preferably 1 mm or more.

[0064] In a preferred embodiment of this design, the flexible cylindrical portion 30 preferably has further flow-suppressing bends on substantially the same circumference as the two flow-suppressing bends. As an example of a preferred embodiment of this design, two outflow-suppressing bent portions 10, 10, which are positioned substantially opposite each other, may be set as one set, and at least one set may be placed on the flexible cylindrical portion 30.

[0065] By providing multiple sets of nearly opposing flow-suppressing bends, it becomes easier to install a pressing section that applies external force in a direction approximately perpendicular to the two flow-suppressing bends 10, 10 that are intended to be the starting points of deformation. This reduces the need for the user to check the position or orientation of the pressing section of the mouthpiece attached to the bag, making it easier for the user to operate.

[0066] As an example of a preferred embodiment of this model, for example, multiple sets of two flow-suppressing bent portions 10,10 may be arranged on the flexible cylindrical portion 30. Multiple sets may be arranged on the flexible cylindrical portion 30 so as to pass through the central axis. For example, two sets of flow-suppressing bent portions may be arranged at positions substantially perpendicular to the central axis, providing a total of four flow-suppressing bent portions 10,10,10,10.

[0067] Furthermore, as a modification of this embodiment, the mouthpiece component may have a flexible cylindrical portion 30 having four outflow-suppressing bent portions 10, 10, 10, 10 on its inner wall. In this modification, the substantially horizontal cross-sectional shape of the flexible cylindrical portion is preferably a substantially circular shape having a hollow flow path 5. In this modification, it is preferable that the inner wall of the flexible cylindrical portion has two sets of two outflow-suppressing bent portions 10, 10, which are arranged at substantially opposite positions on the circumference and serve as the starting point for deformation when external pressure is applied. In this modification, these two sets may be arranged at positions substantially perpendicular to the central axis. In this modification, a pressing portion 35 for pressurizing each outflow-suppressing bent portion may be provided on the outer wall of the flexible cylindrical portion, and four of these pressing portions 35 may be provided at positions substantially perpendicular to the central axis. In addition, this modification may be a flexible cylindrical portion 30 having pressing surfaces on the outside of each of the four bent portions. This modified version has the advantage that the user can easily recognize the pressing surface and apply force because the pressing surface is located in four directions on the outer wall. Furthermore, in this modified version in which the cross-sectional shape of the hollow channel is approximately circular, the configuration may be such that there is only one set of two outflow-suppressing bends 10, 10.

[0068] Furthermore, as a preferred embodiment of this design, for example as shown in Figure 4B, it is preferable that two first outflow-suppressing bends 10, 10 are arranged in the flexible cylindrical portion 30 at positions substantially opposite each other in the longitudinal direction, and that one or more (for example, two, three, four, etc.) second outflow-suppressing bends 12 are arranged on the inner wall of the hollow flow channel side so as to be adjacent to or near both sides of one of the first outflow-suppressing bends 10. The distance between the outflow-suppressing bends when they are near each other is preferably 0.05 mm or less as a lower limit, more preferably 0.1 mm or more, and even more preferably 0.5 mm or more, and the upper limit is not particularly limited but may be 1 mm or 2 mm or less, or it may be the shortest distance from end to end of these bends. Also, outflow-suppressing bends are not required to be provided on the inner wall of the portion that is subjected to force. When force is applied, the inner wall of the hollow channel in the applied portion comes into contact with the applied force, and this force is directed outward on both sides in the longitudinal direction, thereby bringing the inner walls of the first outflow-suppressing bent portions 10, 10 closer together or into contact. Furthermore, the applied force extends the opening portion on the circumference of the second outflow-suppressing bent portion 12, increasing the circumference and applying an outward pushing force to the tips of the first outflow-suppressing bent portions 10, 10, making it easier for the inner walls of the bent portions to come into contact. As a result, the inner wall on the hollow channel side becomes more tightly fitted, and the gaps at both ends in the longitudinal direction can be further reduced.

[0069] The shapes of the first and second flow-suppressing bends are preferably roughly triangular prisms, and their roughly horizontal cross-sectional shapes are preferably notched, open to the inside, such as a V-shape. The shape of the second flow-suppressing bend 12 (depth, angle, width, height, three-dimensional shape, etc.) can appropriately adopt the shape of the first flow-suppressing bend 10, for example, the bend 12 is preferably notched, open to the outside, such as a V-shape.

[0070] Furthermore, as a preferred embodiment of this design, as shown in Figure 4C, two first flow-suppressing bends 10, 10 are arranged on the flexible cylindrical portion 30 at positions substantially opposite each other in the longitudinal direction, and two third flow-suppressing bends 13, 13 are arranged on either side of one of the first flow-suppressing bends 10, forming outward-opening sections created by the surface of the outer wall and the surface of a section 35 protruding from the outer wall. Alternatively, pressing sections 35 protruding from the outer wall may be arranged on the front and back of the flexible cylindrical portion 30, respectively, and these may be used as force-applying sections, with third flow-suppressing bends 13, 13 formed at both ends of the protruding pressing sections 35. The angle of these third flow-suppressing bends 13 (the angle between the outer wall of the flexible cylindrical portion and the side wall of the pressing section 35) is preferably obtuse. Furthermore, flow-suppressing bends do not need to be provided on the inner wall of the force-applying section. The surface of the protruding pressing portion 35 is subjected to force, and this force is directed outward in the longitudinal direction. As a result, a force is applied to the tips of the first outflow-suppressing bent portions 10, 10, pushing them outward, making it easier for the inner walls of the bent portions to make contact. This makes it easier for the inner walls of the hollow flow path to adhere more tightly, and further reduces the gaps that form at both ends in the longitudinal direction.

[0071] The shape of the third outflow-suppressing bend 13 (depth, angle, width, height, three-dimensional shape, etc.) can be appropriately adopted from the shape of the first outflow-suppressing bend 10. For example, a roughly triangular prism shape is preferred, and the roughly horizontal cross-sectional shape is preferably a notched shape, an open shape to the outside, such as a V-shape. The shape of the first outflow-suppressing bend here can be appropriately adopted from the configuration of the first outflow-suppressing bend 10 described above. Furthermore, the second outflow-suppressing bend described above may also be appropriately adopted.

[0072] The overall length of the mouthpiece component 1 is not particularly limited, but is preferably 1 to 100 mm, more preferably 5 to 90 mm, and even more preferably 10 to 70 mm.

[0073] The diameter or maximum length of the hollow channel 5 in the substantially horizontal direction is not particularly limited, but is preferably 1 to 50 mm, more preferably 5 to 45 mm, and even more preferably 8 to 40 mm. When the hollow channel 5 is substantially elongated elliptical, the major axis is not particularly limited, but is preferably 1 to 50 mm, more preferably 5 to 45 mm, and even more preferably 8 to 40 mm. The minor axis is not particularly limited, but is preferably 1 to 50 mm, more preferably 5 to 45 mm, and even more preferably 8 to 40 mm. Furthermore, the diameters of the hollow channels in the mounting portion 20, the flexible cylindrical portion 30, and the sealing portion 40 may also be appropriately combined by adopting the upper and lower limits of the numerical range of the diameter of the hollow channel 5 (which may also be the major and minor axes when it is approximately elliptical). Note that the diameter may be the diameter, the maximum minor axis, or the maximum minor axis.

[0074] The wall thickness of the mouthpiece part 1 is not particularly limited, but is preferably 0.1 to 25 mm, more preferably 0.2 to 23 mm, and even more preferably 0.5 to 20 mm. The wall thicknesses of the mounting part 20, the flexible cylindrical part 30, and the sealing part 40 may also be appropriately combined by adopting the upper and lower limits of the numerical range for the wall thickness of the mouthpiece part 1. For example, the wall thickness of the flexible cylindrical part of the mouthpiece part 1 is not particularly limited, but is preferably 0.1 to 25 mm, more preferably 0.2 to 23 mm, and even more preferably 0.5 to 20 mm.

[0075] The attachment portion 20 is preferably a portion that is attached to the bag portion 101 or its outlet. The sealing portion 40 is preferably a portion that discharges the contents (preferably excrement) to the outside. Each of these portions preferably has a flow path on its inside, and these flow paths are connected to form a flow path that can discharge excrement from the stoma to the outside.

[0076] The cross-sectional shapes in the direction of the flow path of the mounting portion 20, the flexible cylindrical portion 30, and the sealing portion 40 are not particularly limited, but it is preferable that they be substantially similar in shape to the hollow flow path and have a wall thickness (wall thickness). Furthermore, the cross-sectional shapes perpendicular to the direction of the flow path of the mounting portion 20, the flexible cylindrical portion 30, and the sealing portion 40 of each part are not particularly limited, but they may be substantially similar in shape to the hollow portion of the hollow flow path in each part, and it is preferable that the wall thickness (wall thickness) of each part 20, 30, and 40 is large.

[0077] The cross-sectional shapes of the mounting portion 20, the flexible cylindrical portion 30, and the sealing portion 40 in the substantially horizontal direction (X-axis and / or Y-axis direction) are not particularly limited, but it is preferable that they have a hollow flow path. Examples of such shapes include substantially circular shapes (e.g., substantially elliptical, substantially perfect circle, etc.), polygonal shapes (triangle, square, pentagon, hexagon, octagon, etc.), and polygonal shapes with rounded corners (rounded rhombus, rounded parallelogram, rounded rectangle, etc.). Examples of polygonal shapes with rounded corners include polygons that are vertically symmetrical and / or horizontally symmetrical with rounded corners. More specific examples include horizontally elongated rounded quadrilaterals and horizontally elongated rounded polygons that are close to elliptical shapes. One or more types selected from these can be used.

[0078] The mounting portion 20 is preferably the region from one end of the mounting portion 10 on the side connecting to the bag portion 101 to the portion connected to and fixed to the bag portion 101. The hollow flow path or the three-dimensional shape of the outer wall of the mounting portion 20 is not particularly limited, but it is preferably tapered in order to facilitate the flow of contents toward the discharge port. Furthermore, from the viewpoint of pouch attachment, the cross-sectional shape of the mounting portion 20 in the substantially horizontal direction is preferably a substantially elliptical shape, such as the shape of a rugby ball.

[0079] The flexible cylindrical portion 30 is preferably a region that can secure a starting point for deformation when an external force is applied, with the bag portion 101 connected and the cap portion 50 inserted. The three-dimensional shape of the hollow channel 5 or outer wall of the flexible cylindrical portion 30 is not particularly limited, but examples include a substantially cylindrical shape (substantially elliptical cylinder, substantially regular cylinder). From the viewpoint of ease of workability, the cross-sectional shape of the flexible cylindrical portion 30 in the substantially horizontal direction is preferably substantially elliptical (preferably substantially elongated elliptical).

[0080] The sealing portion 40 is preferably the region from one end of the sealing portion 40 on the side into which the cap portion 50 is inserted, to the tip of the cap portion 50 when the cap portion is inserted into the sealing portion 40. From the viewpoint of inserting the cap portion 50, the three-dimensional shape of the hollow channel 5 or outer wall of the sealing portion 40 is preferably approximately cylindrical or approximately elliptical. From the viewpoint of ease of workability, the cross-sectional shape of the sealing portion 40 in the substantially horizontal direction is preferably substantially circular, such as substantially elliptical or substantially circular, and preferably substantially elliptical (preferably substantially elongated elliptical).

[0081] The mouthpiece component used in this embodiment may be a medical component, and is preferably a medical component used in one or more types selected from, for example, ostomy pouches, drainage pouches, defecation bags, urine collection bags, urine collection bags, leg bags, etc. In the case of a mouthpiece component used as a medical component, it may be a mouthpiece component for an excrement collection device. A bag used to accumulate a large amount of excrement preferably comprises a connecting part that connects to the outlet or stoma opening of an ostomy device with a tube or the like, a bag for accumulating excrement, and a mouthpiece used in this embodiment for discharging the accumulated excrement to the outside.

[0082] The mouthpiece component described above is preferably attached to the bag portion 101 (preferably a waste collection bag), and the waste collection bag can be a pouch, a bag, etc., but is not limited to these. Of these, the mouthpiece component is preferably attached to the pouch or bag in which the waste is collected, but the use of the pouch is not particularly limited, and examples include stomas (e.g., colostomy, ileostomy, urostomy, etc.), drains, etc., and one or more of these can be selected. Furthermore, the mouthpiece component described above is more preferably a mouthpiece for an excrement container used for low-viscosity excrement, and the low-viscosity excrement container is preferably one or more types selected from, for example, those for ileostomy and those for urostomy.

[0083] As shown in Figures 1 and 8, the mouthpiece component 1 may be provided with a sealing portion 40 for sealing the discharge of contents to the outside, and a cap portion 50 for inserting into the sealing portion 40 to seal the flow of contents, and the cap portion 50 can further suppress leakage of contents. For example, from the viewpoint of further suppressing the leakage of contents as described above, it is preferable that the mouthpiece component 1 further includes a cap portion 50 that can be inserted into and in contact with the opening (discharge port) for discharge of the sealing portion of the mouthpiece component 1, and the cap portion may have one or more pleats. In this embodiment, it is preferable that the mouthpiece component 1 is integrally molded with the cap portion 50. Alternatively, it may be an integrally molded product of the mouthpiece component 10, the cap portion 50 and a connecting portion for connecting to the cap portion, and the connecting portion may be connected to any part provided on the mouthpiece component 1, for example, it may be connected to the outside between the flexible cylindrical portion 30 and the sealing portion 40. The medical component may include a one-piece molded product in which the mouthpiece component 1 and the cap portion 50 are integrally molded. Preferably, the mouthpiece component 1 and the cap portion 50 are molded from the same resin material, and more preferably, the resin material is a flexible resin material.

[0084] The mouthpiece component 1 described above can be molded using a resin material as the raw material and known molding methods such as injection molding. Examples of resin materials that can be used include ultraviolet curing resin, thermoplastic elastomer resin, urethane resin, silicone resin, synthetic rubber, natural rubber, and thermoplastic resin. In this embodiment, flexible resin is preferred from the viewpoint of adjusting the force applied by fingers, etc.

[0085] 3. A storage bag (preferably a waste storage device) according to this embodiment.

[0086] This embodiment provides a bag portion having the mouthpiece component 1 described above. The bag portion is preferably for containing contents, and may be a storage bag or storage device. The contents contained in the bag portion may be excrement. In a preferred embodiment, an excrement storage device can be provided comprising a mouthpiece component 1 and an excrement storage bag (preferably a pouch for excrement from a stoma) for containing excrement, wherein the excrement storage bag has a sealing portion 40 for discharging or sealing the excrement with a cap portion 50, and a mounting portion for a medical component is attached to the outlet.

[0087] Examples of waste collection devices include ostomy appliances, drainage pouches, defecation bags, urine collection bags, and leg bags, from which one or more types can be selected.

[0088] An excrement collection device according to one embodiment of the present invention will be described with reference to Figure 12 and other figures. Figure 12 is a front view showing an example of the configuration of a collection bag 100 according to one embodiment of the present invention.

[0089] The storage bag 100 shown in Figure 12 is more preferably an ostomy appliance. The bag portion 101 is formed into a sealed bag shape using a plastic film. The storage bag 100 may have an opening 103 into which the contents flow in, and the opening 103 may be located anywhere on the storage bag, but it is preferable to have it located at the top. For example, in the case of the storage bag 100, a faceplate 102 is provided at the top of the storage portion 101. The adhesive layer of this faceplate 102 allows the storage portion 101 to be attached to the patient's stoma. The patient's excrement is discharged into the pouch 101 through the holes 103 in the faceplate 102 and is stored there.

[0090] As shown in Figure 12, a storage bag 100 according to one embodiment comprises a mouthpiece component 1 and a storage section (e.g., a pouch) 101 that contains excrement from the stoma. The storage section 101 has an outlet from which the contents (preferably excrement) are discharged, and this outlet is connected to the attachment portion 20 of the mouthpiece component 1. The sealing portion 40 of the mouthpiece component 1 has a cap portion 50 inserted into it to seal off the discharge of excrement. By maintaining this sealed state, excrement is not discharged from the excrement storage device 100 containing the excrement.

[0091] As shown in Figure 10, when the part of the mouthpiece component 1 to which force is applied is pressed with a finger or the like, the hollow channel inside the applied outer wall is compressed. Then, force is applied in the outward direction to each of the outflow-suppressing bends 10, 10 located at both ends in the outward direction approximately perpendicular to the applied force. Due to this applied force, the outflow-suppressing bends, which are the starting points of deformation, deform so that their inner walls come into contact with or close to each other. The gaps that occur at both ends due to the outflow-suppressing inflection points are significantly reduced or eliminated. As a result, the flow of contents in the hollow channel can be blocked or suppressed. By releasing the force, the space in the hollow channel returns to its original state, and the flow of contents can be permitted or started. This makes it easy to discharge the contents from the storage bag. Also, since the force can be applied easily, discharge suppression can be easily achieved. Furthermore, the state of suppressing the discharge of contents can be easily set and maintained by applying an external force, and the open state can also be easily set by adjusting the amount of force applied, so the scattering of contents can be suppressed more effectively.

[0092] Therefore, the operation of discharging the contents from the containment bag, especially suppressing discharge, can be easily performed. In addition, when living with the containment bag 100 attached, the disposal of excrement can be easily carried out. [Examples]

[0093] The effects of the present invention will be specifically described below with reference to examples. However, the scope of the present invention is not limited to the examples described herein.

[0094] <Manufacturing Example 1> The medical components (mouthpieces in Example 1 and Comparative Example 1) were manufactured by injection molding using a flexible thermoplastic resin.

[0095] <Mouthpiece component of Example 1> The mouthpiece component of Example 1 has the external shape shown in Figures 1, 2, and 5, and the notches 10, 10 have the shapes shown in Figures 4A, 3B, and 6. The mouthpiece component 1 of Example 1 has a sealing portion 40 in which the mounting portion 20, flexible cylindrical portion 30, and cap portion 50 are connected via a connecting portion, and the sealing portion 40 is integrally molded from flexible resin.

[0096] As shown in Figure 12, the fitting part 1 was attached to the bag portion 101 to obtain a storage bag 100 having the fitting part 1. In Example 1, the external shape of the attachment portion 20 and the flexible cylindrical portion 30 is tapered towards the outlet when viewed from the front, and the external shape of the sealing portion is approximately rectangular when viewed from the front. Regarding the attachment portion 20 and the flexible cylindrical portion 30, the major and minor axes of the hollow flow path of the attachment portion 20 are slightly larger than the major and minor axes of the hollow flow path of the flexible cylindrical portion 30, and are tapered to allow the contents to flow easily towards the outlet. In addition, the cross-sectional shape of the fitting part 1 in a direction approximately perpendicular to the approximately central axis is a horizontally elongated, approximately elliptical shape.

[0097] The total length of the mouthpiece component 1 in the flow path direction was 45 mm. In the mounting portion 20, the major diameter of the hollow channel 5 was 33 mm and the minor diameter was 10 mm, with a wall thickness of 7 mm on the major diameter side and 2 mm on the minor diameter side. In the flexible cylindrical portion 30 and the sealing portion 40, the major diameter of the hollow channel 5 was 25 mm and the minor diameter was 10 mm, with a wall thickness of 3 mm. The notches 10,10 had a depth (D) of 2.0 mm, an angle (α°) of 80 degrees, a width (W) of 4.5 mm, and a height (H) of 7.5 mm.

[0098] <Oral fitting component of Comparative Example 1> The mouthpiece component of Comparative Example 1 was manufactured in the same manner as the mouthpiece component of Example 1, except that it did not have a notch.

[0099] <Evaluation of ease of flow rate adjustment> (1) The dog food was degreased, water was added to adjust the moisture content to 90%, and it was mixed in a blender for 1 minute. (2) Put 100g of (1) as described above into the pouch with the mouthpiece attached, and with the mouthpiece facing downwards while sealing the fingers with the mouthpiece. (3) Points were awarded based on the weight of the contents expelled from the mouthpiece within 10 seconds. 1 item: 45g or more. 2 points: 30g or more, less than 45g. 3 points: 15g or more, less than 30g. 4 points: 1g or more, less than 15g. 5 points: Less than 1g.

[0100] [Table 1]

[0101] As shown in Figure 11, pressure was applied to the central part of the flexible cylindrical section 1030 of Comparative Example 1 by pinching it with the thumb and index finger. The hollow channel 1005 near the center became tightly sealed due to the applied pressure, but elongated, roughly elliptical spaces remained at both ends along the long axis. Even when the pressure was increased, the spaces at both ends remained unchanged. Because the contents flowed out towards the discharge port through the remaining gaps at both ends, it was not easy to suppress discharge.

[0102] As shown in Figure 10A, in Example 1, pressure was applied to the pressing areas 35, 35 near the center of the flexible cylindrical portion 30, between the notches 10, 10 on its circumference, by pinching them with the thumb and index finger. In Figure 10B, the inner wall on the hollow channel 5 side near the center became tightly sealed due to the applied pressure, and the inner walls at both ends in the longitudinal direction also became tightly sealed. As a result, discharge suppression was made particularly easy, and the operation of discharging the contents from the storage bag was made easy.
