Description

[Technical Field]

[0001] The present invention relates to a spouted container, and more particularly to a spouted container that can reduce the gap between the lips and the spout when held in the mouth. [Background technology]

[0002] Swallowable foods (liquid foods) are available for users who have difficulty eating solid foods. Retort pouches (bag-shaped containers) are known as containers for these foods for swallowing, but they have the problem of being time-consuming because the pouch must be opened and the food must be taken out using a spoon or the like.

[0003] For this reason, containers with spouts are used, in which the container body, such as a pouch, is filled with contents such as swallowable food, and the user holds the spout (drinking opening) in their mouth and sucks out the contents from the container body, or squeezes the container body to push out the contents (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2008-74443 Summary of the Invention [Problem to be solved by the invention]

[0005] In the spout-equipped container described in Patent Document 1, the spout is cylindrical, so if the user does not have enough strength to close the mouth, a large gap will form between the lips and the spout, making it difficult to suck out the contents or causing the contents supplied to the mouth to spill out through the gap between the lips and the spout.

[0006] The present invention aims to solve the above problems and to provide a spouted container that can reduce the gap between the lips and the spout when the user holds the spout in their mouth, using fewer parts while taking into consideration costs and manufacturing processes. [Means for solving the problem]

[0007] In order to solve the above-mentioned problems, the present invention provides a spout-equipped container comprising a container body into which contents are filled, a spout attached to the container body, and a cap that closes the top of the spout, wherein the spout comprises an attachment tube portion attached to the opening of the container body, a nozzle portion erected on the top of the attachment tube portion and forming a discharge tube on the inside, and a plug member that closes the discharge tube via a thin-walled weakened portion, the nozzle portion has a jaw-shaped outer peripheral wall whose outer peripheral surface is shaped to fit the closed lips, and the cap engages with the plug member of the nozzle portion when opened, thereby removing the plug member.

[0008] In one embodiment of a spout-equipped container, the outer wall of the mouth is configured to be spindle-shaped when viewed from above, with arc portions that match the top and bottom shapes of the mouth when held, acute-angled protruding portions that match the left and right corner shapes of the mouth when held, and curved sides that gently connect the ends of the front and back arc portions and the ends of the left and right acute-angled protruding portions.

[0009] As a specific embodiment of a spout-equipped container, the plug member comprises a partition wall that closes the discharge tube via a thin-walled weakened portion, and a cylindrical wall that stands up from the partition wall and has an engaging protrusion formed on its outer periphery, and the cap comprises a top wall that covers the upper surface of the nozzle portion, a sealing tube that hangs down from the top wall and comes into close contact with the discharge tube when the lid is closed, and an inward engaging protrusion that protrudes from the inner periphery of the sealing tube and engages with the engaging protrusion on the cylindrical wall, and the cap comprises a gripping outer wall that stands up from the outer edge of the top wall, and a cover portion that hangs down from the lower end of the gripping outer wall via a weakened piece and surrounds the gripping outer wall of the nozzle portion. [Effects of the Invention]

[0010] The spout-equipped container of the present invention has a nozzle portion of the spout whose outer periphery is formed to resemble the shape of the mouth when held in the mouth, thereby reducing the gap between the lips and the outer periphery of the nozzle portion, preventing air from leaking between the lips and the nozzle portion and preventing the contents from spilling, and allowing the contents to be steadily supplied to the mouth.

DETAILED DESCRIPTION OF THE INVENTION

[0012] Next, the spouted container of the present invention will be described with reference to the drawings showing an embodiment. In the following description, the direction in which the cap B is positioned relative to the container body C is referred to as the top (upward as viewed in Figure 1(a)), and the opposite direction is referred to as the bottom. The flattened direction of the outer periphery of the spout A is referred to as the front-to-back direction, and the longitudinal direction is referred to as the left-to-right direction.

[0013] Example 1 In FIG. 1, A is a spout attached to a container body C such as a pouch, and B is a cap that closes the top of the spout A.

[0014] As shown in Figures 1 and 2, the spout A is sandwiched within the opening seal portion 1, which is the opening of the container body C, and sealed by heat welding or the like, and is equipped with an attached tubular portion A1, the inside of which forms a flow path 3, and a nozzle portion A2, which is erected on top of the attached tubular portion A1, forms a flow path inside, and has an outer periphery shaped to be held in the user's mouth when using the contents.

[0015] The tubular attachment part A1 has a cylindrical shape with its outer periphery sandwiched and sealed by the opening seal part 1, which is the opening of the container body C, and with a flow path 3 secured inside, and in this embodiment, is formed so that its outer periphery is flat in the front-to-rear direction and protrudes in the left-to-right direction so that it can be sandwiched between the opening seal part 1 formed between the two front and rear sheets of the pouch container. In other words, the spout A is attached to the container body C by, for example, heat welding the opening seal part 1 to the outer periphery surface of the tubular attachment part A1, which extends in the left-to-right direction.

[0016] As shown in Figures 1, 2 and 4(b), the nozzle portion A2 has an outer periphery formed so that when the user holds the nozzle in their mouth to use the contents, there is no gap between the nozzle portion A2 and the lips L, and the nozzle portion A2 is composed of an outer peripheral wall 5 which is held in the mouth and whose inner periphery is connected to the flow path 3, an upper wall 6 which is connected to the upper end of the inner periphery of the outer peripheral wall 5 to close the inside and has an opening 6a drilled in the center, a discharge tube 7 which hangs down from the periphery of the opening 6a in the upper wall 6, and a plug member D which is connected to the lower end of the inner periphery of the discharge tube 7 via a breakable thin-walled weakened portion 8.

[0017] The outer jaw wall 5 is composed of arc portions 5a on the front and back that match the top and bottom shape of the jaw, acute-angled protrusions 5b on the left and right that have rounded ends that form acute angles to match the shape of the left and right corners of the jaw, and curved side portions 5c that gently connect the ends of the front and back arc portions 5a and the left and right acute-angled protrusions 5b, with the arc portions 5a curving in an outwardly convex arc shape, the acute-angled protrusions 5b curving in a left-right convex arc shape, and the curved side portions 5c curving in an inwardly convex arc shape, and as a whole, it is formed in a shape that gently bulges outward including the arc and protrudes at rounded acute angles in the left-right direction, for example a spindle shape.

[0018] The plug member D is connected to the lower end of the inner periphery of the discharge tube 7 via a thin-walled weakened portion 8, and is composed of a partition wall 10 that closes the inside of the discharge tube 7 together with the thin-walled weakened portion 8, and a cylindrical wall 11 that stands on the upper surface of the partition wall 10 and engages with the cap B.

[0019] The cylindrical wall 11 has a plurality of equally spaced engaging protrusions 12 extending vertically on the outer periphery and adapted to engage with the cap B, and an annular inner periphery engaging protrusion 13 protruding from the upper inner periphery. In this embodiment, the plurality of engaging protrusions 12 are formed so as to engage with a plurality of inward engaging protrusions 25 disposed on the inner periphery of a sealing cylinder 19 of a cap B, which will be described later.

[0020] As shown in FIGS. 1 and 3, the cap B has a lower surface that is close to the upper surface of the upper wall 6 of the nozzle portion A2 and the upper end surface of the gripping outer peripheral wall 5, and is formed in a shape that is larger than the shape of the gripping outer peripheral wall 5 when viewed from above by the wall thickness of the gripping outer peripheral wall 16. The cap B also has a top wall 15 that has an opening 15a drilled in the center, a gripping outer peripheral wall 16 that stands up from the outer edge of the top wall 15, and a step that closes the opening 15a with a step above the periphery of the opening 15a of the top wall 15. The step top wall 17 has a top wall 17, and from the underside thereof, near the center, there is an attachment tube portion 18 which engages with the inner periphery of the cylindrical wall 11 of the stopper member D, and on the outer periphery of the attachment tube portion 18 there is a sealing tube 19 whose outer periphery is in close contact with the upper inner periphery of the discharge tube 7 of the nozzle portion A2 when the lid is closed.In addition, there is a cover portion 21 which is attached in a breakable manner via a plurality of weakened pieces 20 and which surrounds and covers the outer periphery of the gripping outer wall 5.

[0021] An outer peripheral engaging protrusion 23 is provided around the lower outer periphery of the engaging cylindrical portion 18, which engages with the inner peripheral engaging protrusion 13 of the cylindrical wall 11 of the plug member D to prevent it from falling off. A plurality of inward engaging protrusions 25 that engage with the engaging protrusions 12 on the outer periphery of the cylindrical wall 11 are arranged on the inner periphery of the sealing cylinder 19 .

[0022] In order to prevent unauthorized opening of the spouted container of this embodiment before use, a shrink label or sealing member, etc., may be provided between the spout A and the cap B, although this is not shown.

[0023] Next, the manner of use and the effects of this embodiment will be described. In the spout-equipped container of this embodiment, when the cover portion 21 of the cap B is placed over the outer periphery of the outer jaw wall 5 of the nozzle portion A2, the sealing tube 19 of the cap B seals the inside of the discharge tube 7 of the nozzle portion A2, and after the attachment tube portion 18 is inserted into the cylindrical wall 11 of the stopper member D, the attachment tube portion A1 of the spout A is inserted into the opening seal portion 1 of the container body C and sealed by heat welding or the like. In this way, after the cap B is set on the nozzle portion A2 and the stopper member D, the spout A with the cap B attached is attached to the container body C, forming a closed spout-equipped container as shown in Figure 1. When the container body C is a pouch container, for example, the contents are filled into the container body C, and then the spout A with the cap B set thereon is attached to the opening seal portion 1 of the container body C. Depending on the structure of the container body C, the contents may be filled at the bottom.

[0024] When cap B is set on top of nozzle portion A2, cover portion 21 of cap B fits to the shape of nozzle portion A2 and surrounds and covers outer peripheral wall 5. At the same time, inward engaging protrusion 25 on the inner periphery of sealing tube 19 of cap B engages with engaging protrusion 12 on the outer periphery of cylindrical wall 11 of plug member D, and outer peripheral engaging protrusion 23 of engaging cylindrical portion 18 rides over inner peripheral engaging protrusion 13 of cylindrical wall 11 to fit and engage, and the outer periphery of sealing tube 19 of cap B is inserted into the inner periphery of discharge tube 7 of nozzle portion A2 to seal the interior. In this way, when setting cap B on spout A, the cover portion 21 of cap B is aligned with the shape of the outer peripheral wall 5 of the nozzle portion A2, and then cap B is inserted from above, whereby cap B and stopper member D easily engage with each other, and cap B can be set on spout A.

[0025] After the spout-equipped container of this embodiment is set, the cover portion 21 of the cap B surrounds and covers the outer peripheral wall 5 of the nozzle portion A2, preventing the outer peripheral wall 5 that is held in the mouth from becoming dirty or damaged, so there is no need for a shrink label or the like between the spout A and the cap B.

[0026] Next, to use the spouted container of this embodiment, first, the gripping outer peripheral wall 16 of the cap B is gripped, and the cap B is rotated relative to the spout A in any direction. When cap B is rotated, the sealing tube 19 of cap B rotates inside the discharge tube 7 of the nozzle portion A2, and the inward engaging protrusion 25 inside the sealing tube 19 engages with the engaging protrusion 12 of the stopper member D, causing the stopper member D to also rotate, thereby breaking the thin-walled weakened portion 8 connecting the rotating stopper member D to the stationary discharge tube 7. In addition, the cover portion 21 is fitted to the outer periphery of the gripping outer wall 5 by adjusting its shape, so that as the cap B gripping the gripping outer wall 16 rotates, the weakened piece 20 connecting the rotating top wall 15 and the non-rotating cover portion 21 is broken.

[0027] After the cap B is rotated, when the cap B is lifted relative to the nozzle portion A2, the seal between the sealing tube 19 of the cap B and the discharge tube 7 of the nozzle portion A2 is released, as shown in Figure 4(a), and the plug member D, which is engaged with the engaging tube portion 18 inside the sealing tube 19, is also removed from inside the discharge tube 7 together with the sealing tube 19, and the inside of the discharge tube 7 opens as a flow path. Furthermore, after lifting and removing the cap B, the cover part 21 remains covering the outer peripheral wall 5 of the nozzle part A2, so that if the contents are not used immediately, the outer peripheral wall 5 held in the mouth is prevented from being soiled or damaged.

[0028] After lifting and removing the cap B, the cover portion 21 remaining on the nozzle portion A2 is grasped and lifted up against the outer peripheral wall 5 to remove it, and the discharge tube 7 becomes an open nozzle portion A2, forming a spouted container.The contents can be discharged from the discharge tube 7 into the mouth by holding the outer peripheral wall 5 of the nozzle portion A2 in the mouth and sucking, or by squeezing the container body C. As shown in Figure 4(b), the nozzle portion A2 of this embodiment is configured with front and rear arc portions 5a, left and right acute-angled protrusions 5b, and curved edges 5c connecting the respective ends of the outer jaw wall 5 to fit the shape of the mouth when the mouth is held, and this reduces the gap between the mouth and the lips L held in the mouth. Therefore, even if a user has a weak ability to close their mouth, air does not leak when inhaling and the contents can be steadily supplied into the mouth, thereby preventing the inhalation of swallowable food for users who have difficulty eating solid food. Furthermore, since the gap between the lips L and the container can be made small, spillage of the contents from the gap between the lips L and the container can be prevented.

[0029] It is desirable to use all of the contents in a short time, but by inserting the sealing tube 19 of the cap B into the discharge tube 7 of the nozzle part A2, the nozzle part A2 can be sealed and closed with the cap B, allowing the contents to be used repeatedly. In this embodiment, the sealing tube 19 of the cap B is inserted into the discharge tube 7 of the nozzle portion A2 and sealed to close the lid, but it is also possible to arrange a screw on the inner periphery of the discharge tube 7 and a screw on the outer periphery of the sealing tube 19 that screws into the discharge tube 7, so that the nozzle portion A2 and the cap B are closed by screwing them together. When the cap B of this embodiment is first opened, the weakened piece 20 connected to the cover portion 21 breaks, leaving a mark, so that it is possible to visually determine from the outside whether the cap has been opened or not, thereby preventing fraudulent acts such as tampering.

[0030] Example 2 Next, a second embodiment will be described in which the configurations of the nozzle portion A2 of the spout A and the cap B of the first embodiment are changed. In the following, the same components as those in the first embodiment are given the same reference numerals, and new reference numerals are given to changed components, and the explanation will focus on the differences.

[0031] In FIG. 5, Aa denotes a spout attached to the container body C, and Ba denotes a cap that closes the top of the spout Aa. As shown in Figure 5, the spout Aa is sandwiched within the opening seal portion 1 of the container body C and sealed by heat welding or the like, and is equipped with an attached tubular portion A1 whose inside forms a flow path 3, and a nozzle portion Aa2 which is erected on top of the attached tubular portion A1, forms a flow path inside, and has an outer periphery shaped to be held in the user's mouth when using the contents.

[0032] The nozzle portion Aa2 has an outer periphery formed so that when the user holds the nozzle in their mouth to use the contents, there is no gap between the nozzle portion Aa2 and the lips L, and the nozzle portion Aa2 is composed of a holding outer wall 30 whose inner periphery is connected to the flow path 3, an upper wall 31 which is connected to the middle of the inner periphery of the holding outer wall 30 to block the inside and has an opening 31a drilled in the center, a discharge tube 32 which stands from the periphery of the opening 31a of the upper wall 31, and a plug member D which is connected to the inner periphery of the opening 31a of the upper wall 31 via a breakable thin-walled weakened portion 33. As shown in FIG. 6, the discharge tube 32 is provided with pressing ribs 35 projecting from the lower outer periphery in the left-right direction.

[0033] As shown in Figure 6(b), the jaw outer peripheral wall 30 is composed of arc portions 30a on the front and back that match the top and bottom shape of the jaw, acute-angled protruding portions 30b on the left and right that have rounded ends that form acute angles to match the shape of the left and right corners of the jaw, and curved side portions 30c that gently connect the ends of the front and back arc portions 30a and the left and right acute-angled protruding portions 30b.As a whole, it is formed in a shape that gradually bulges out in the front and back direction, including the arc, and protrudes at rounded acute angles in the left and right direction, for example, in a spindle shape, and an inner peripheral locking recess 34 is recessed into the upper part of the inner circumference.

[0034] The cap Ba has a lower end surface formed in the same shape as the upper end surface of the gripping outer peripheral wall 30 of the nozzle portion Aa2, and is provided with a gripping outer peripheral wall 40 that is close to the upper end surface of the gripping outer peripheral wall 30, an inclined top wall 41 that is inclined downward and inward from the lower inner peripheral end of the gripping outer peripheral wall 40 and has an opening 41a in the center that is larger than the outer diameter of the discharge tube 32 of the nozzle portion Aa2, and a stepped top wall 42 that has a step above the inner edge of the opening 41a of the inclined top wall 41 and blocks the inside, and the lower surface of the stepped top wall 42 has a step from near the center An attachment tube portion 43 is attached to the inner circumference of the cylindrical wall 11, and a sealing tube 44 is hung from the outer peripheral side of the attachment tube portion 43, and its outer circumference is in close contact with the upper inner circumference of the discharge tube 32 of the nozzle portion Aa2 when the lid is closed.In addition, an attachment member 46 is formed around the periphery of the opening 41a on the underside of the inclined top wall 41, which is connected to the inner edge of the underside of the inclined top wall 41 via a plurality of breakable weakening pieces 45 and is attached between the inner circumference of the outer peripheral wall 30 of the nozzle portion Aa2 and the outer circumference of the discharge tube 32.

[0035] An outer peripheral engaging protrusion 48 is provided around the lower outer periphery of the engaging cylindrical portion 43 to engage with the inner peripheral engaging protrusion 13 of the cylindrical wall 11 of the plug member D to prevent it from falling off. A plurality of inward engaging protrusions 49 that engage with the engaging protrusions 12 on the outer periphery of the cylindrical wall 11 are arranged on the inner periphery of the sealing cylinder 44 .

[0036] When viewed from above, the mounting member 46 has approximately the same shape as the inner peripheral shape of the gripping outer peripheral wall 30 (preferably slightly smaller), and is separated in the center at a distance slightly larger than the outer diameter of the discharge tube 32. At the top of the outer periphery, an outer peripheral locking protrusion 50 is protruded, which engages with and locks into the inner peripheral locking recess 34 of the gripping outer peripheral wall 30 when the outer periphery is set.

[0037] Next, the manner of use and the effects of this embodiment will be described. In this embodiment, the spout-equipped container is formed by positioning the cap Ba to match the shape of the outer peripheral wall 30 of the nozzle portion Aa2 and setting it on top of the nozzle portion Aa2, and then inserting the mounting tubular portion A1 of the spout Aa into the opening seal portion 1 of the container body C and sealing it by heat welding or the like, resulting in a closed spout-equipped container as shown in Figure 5.

[0038] When the cap Ba is set on top of the nozzle portion Aa2, the inward engaging protrusion 49 on the inner periphery of the sealing tube 44 of the cap Ba engages with the engaging protrusion 12 on the outer periphery of the cylindrical wall 11 of the stopper member D, and the outer periphery engaging protrusion 48 on the outer periphery of the engaging tube portion 43 climbs over the inner periphery engaging protrusion 13 of the cylindrical wall 11, fits into and engages with it, and the outer periphery of the sealing tube 44 of the cap Ba is inserted into the inner periphery of the discharge tube 32 of the nozzle portion Aa2, sealing the inside. Furthermore, the mounting member 46 of the cap Ba is engaged between the inner circumference of the outer peripheral wall 30 of the nozzle portion Aa2 and the pressing rib 35 protruding from the outer circumference of the discharge tube 32 by the engagement between the inner circumference locking recess 34 and the outer circumference locking protrusion 50, and is attached so as not to fall off.

[0039] In the spout-equipped container of this embodiment, the outer peripheral engaging protrusion 48 of the engaging tubular portion 43 of the cap Ba engages with and engages with the inner peripheral engaging protrusion 13 of the tubular wall 11 of the stopper member D connected to the nozzle portion Aa2, and the mounting member 46 of the cap Ba is attached between the inner periphery of the outer clamping wall 30 of the nozzle portion Aa2 and the pressure rib 35 on the outer periphery of the discharge tube 32, so that the cap Ba can be attached without any rattling and will not fall off the nozzle portion Aa2.

[0040] Next, to use the spouted container of this embodiment, first, the gripping outer peripheral wall 40 of the cap Ba is gripped, and the cap Ba is rotated in any direction relative to the spout Aa. When the cap Ba is rotated, the sealing tube 44 of the cap Ba rotates inside the discharge tube 32 of the nozzle portion Aa2, and the inward engaging protrusion 49 inside the sealing tube 44 engages with the engaging protrusion 12 of the plug member D, causing the plug member D to also rotate, thereby breaking the thin-walled weakened portion 33 connecting the rotating plug member D to the stationary discharge tube 32. Furthermore, the mounting member 46 is attached and fixed between the inner circumference of the gripping outer wall 30 of the nozzle portion Aa2 and the pressure rib 35 on the outer circumference of the discharge tube 32, so that as the cap Ba gripping the gripping outer wall 40 rotates, the weakened piece 45 connecting the rotating inclined top wall 41 and the non-rotating mounting member 46 is broken.

[0041] After the cap Ba is rotated, when the cap Ba is lifted relative to the nozzle portion Aa2, the seal between the sealing tube 44 of the cap Ba and the discharge tube 32 of the nozzle portion Aa2 is released, as shown in Figure 6(a), and the plug member D attached to the attachment tube portion 43 inside the sealing tube 44 is also removed from inside the discharge tube 32 together with the sealing tube 44, opening the inside of the discharge tube 32 as a flow path. Furthermore, after the cap Ba is lifted and removed, the mounting member 46 remains fixed inside the outer peripheral wall 30 of the nozzle portion Aa2.

[0042] As shown in Figure 6(b), the nozzle portion Aa2 of this embodiment is configured such that the outer peripheral wall 30 of the mouthpiece is configured with front and rear arc portions 30a, left and right acute-angled protrusions 30b, and curved edges 30c connecting the respective ends to fit the shape of the mouth when the mouthpiece is held. This reduces the gap between the mouthpiece and the lips L, so that even users with weak mouth-closing strength can inhale without air leaking and the contents can be steadily supplied into the mouth, preventing the inhalation of swallowable food for users who have difficulty eating solid food. Furthermore, since the gap between the lips L and the container can be made small, spillage of the contents from the gap between the lips L and the container can be prevented.

[0043] It is desirable to use all of the contents in a short time, but by inserting the sealing tube 44 of the cap Ba into the discharge tube 32 of the nozzle portion Aa2, the nozzle portion Aa2 can be sealed and closed with the cap Ba inside the container, allowing the contents to be used repeatedly. Other functions and effects are the same as those of the first embodiment. [Industrial Applicability]

[0044] The spout-equipped container of the present invention has a nozzle portion of the spout that is shaped to resemble the shape of the mouth when held in the mouth, reducing the gap between the lips and the nozzle portion, preventing air from leaking between the lips and the nozzle portion and the contents from spilling, and allowing the contents to be steadily supplied to the mouth.As such, the spout-equipped container can be widely used as a container for semi-solid (gel-like, etc.) foods to be swallowed.
