FIG. 10 is a cross-sectional view taken along the line XIII-XIII of FIG.

The details of the embodiment of the present invention will be described below with reference to the drawings. First, the configuration of the combination according to the present embodiment will be described in detail. FIG. 1 is a front view illustrating the combination 1 according to the present embodiment. As illustrated in FIG. 1, the combination 1 has a tube container 10 and a liquid discharge container 30. The combination 1 is used with the tube container 10 attached. Here, for convenience of explanation, the vertical directions in FIG. 1 in which the normal usage state of the combination 1 is shown are up and down, respectively. However, in FIGS. 2 to 5 and 7 to 9 in which the tube container 10 is shown alone, the top and bottom are shown in the opposite directions.

FIG. 2 is a front view of the tube container 10. In FIG. 2, the tube container 10 is shown upside down from that in FIG. The tube container 10 contains a liquid as the contents. The liquid here is preferably a low-viscosity content such as water having a viscosity of 1 mPa · s, but is a content having a viscosity of about 2 to 3 Pa · s such as shampoo. It doesn't matter. Further, the tube container 10 may be provided with an overcap (not shown).

The tube container 10 has a head molded body 13 composed of a mouth portion 11 and a shoulder portion 12 connected thereto. The tube container 10 has a body portion 14 connected to the head molded body 13. The cylindrically formed mouth portion 11 defines an opening 15 on the inner peripheral side thereof. The liquid is discharged from the tube container 10 by passing through the opening 15. The shoulder portion 12 is formed in a truncated cone shape that expands to the outside of the tube container 10 as the distance from the mouth portion 11 increases.

The body portion 14 is a film-like laminate formed into a tubular shape. Then, one end of the body portion 14 extending in a tubular shape is joined to the shoulder portion 12. On the other hand, the other end of the body portion 14 is sealed by the bottom seal portion 16 in which the inside of the tubular body portion 14 is overlapped and adhered. The bottom seal portion 16 may be adhered after the body portion 14 is filled with the contents. In particular, the body portion 14 of the tube container 10 has the flexibility of deforming according to a change in the internal pressure when the contents are sucked out and becomes a negative pressure, and when the change in the internal pressure becomes large. It is good that it is configured to maintain independence.

The tube container 10 may be made of a transparent material. In particular, if the shoulder portion 12 and the body portion 14 in the vicinity of being joined to the shoulder portion 12 are transparently configured, the remaining amount of the liquid may be visually recognized.

FIG. 3 is an enlarged front view of a part of the tube container 10. The mouth portion 11 is formed with protrusions 17 that project outward in an annular shape from the outer peripheral surface. The protrusion 17 is composed of a guide surface 18 on the side of the opening 15 and a return surface 19 on the side of the shoulder portion 12. The guide surface 18 is composed of a gentle slope that extends outward from the tube container 10 as the distance from the end of the opening 15, that is, the end of the mouth portion 11 increases. On the other hand, the return surface 19 is composed of a steep slope that narrows inside the tube container 10 as the distance from the end of the opening 15 increases. The return surface 19 may be perpendicular to the outer peripheral surface of the mouth portion 11.

FIG. 4 is an enlarged cross-sectional view of a part of the tube container 10. The head molded body 13 includes an opening sealing portion 20 that blocks the passage of liquid at the opening 15. The opening sealing portion 20 is integrally molded with the mouth portion 11. The opening sealing portion 20 is configured to seal the tube container 10 so as to be breakable. The opening sealing portion 20 illustrated in FIG. 4 is formed in a disk shape covering the entire surface of the opening 15.

A thin-walled portion 21 having a thickness smaller than that of other portions is provided by forming a groove on the peripheral edge of the opening sealing portion 20 on the side of the opening 15. The thin portion 21 is connected to the inner peripheral surface of the mouth portion 11. Since the connection portion of the opening sealing portion 20 with the mouth portion 11 is a thin-walled portion 21, the opening sealing portion 20 can be broken from the mouth portion 11 without requiring a strong force.

By having the opening sealing portion 20, it is possible to manufacture the tube container 10 in which the mouth portion 11 is sealed in the initial state. Therefore, it is not necessary to adhere the easy-to-open seal, which is widely used for sealing and is peeled off at the time of initial opening, to the end of the mouth portion 11, and the number of parts and the manufacturing process can be reduced. Further, when using the tube container 10, it is possible to save the trouble of peeling off the easy-to-open seal.

The opening sealing portion 20 here may be formed separately from the mouth portion 11 as long as it is configured to be broken by piercing. For example, instead of the opening sealing portion 20, the above-mentioned easy-opening seal (not shown) may be used. The easy-to-open seal is attached to the mouth portion 11 so as to cover the opening 15. The mouth portion 11 and the easy-to-open seal may be attached with an adhesive or heat-sealed. Even if such an easy-to-open seal is used for the liquid discharge container 30, it can be applied as long as the diameter is correct, and the liquid discharge container 30 has high versatility.

The easy-to-open seal here does not necessarily have to have easy-openability. However, it is preferable that the easy-to-open seal has a tightness of the tube container 10 but not so high in piercing strength and low tearing strength. Therefore, a single-layer film made of aluminum foil, biaxially stretched polypropylene (Oriented Polypropylene) or the like, a multilayer film in which these are laminated, or the like can be applied to the easy-to-open seal.

A connecting portion 22 may be formed as a function of preventing the broken opening sealing portion 20 from falling off. The connecting portion 22 is formed, for example, in a thick-walled structure at a connecting portion of the opening sealing portion 20 with the mouth portion 11. The connecting portion 22 keeps the connection with the mouth portion 11 of the broken opening sealing portion 20 and does not block the flow of the liquid.

The thin-walled portion 21 may be formed over the entire circumference of the opening sealing portion 20, but may be omitted in a portion that overlaps with the connecting portion 22 in a plan view. Further, in the case where the thin-walled portion 21 is partially omitted, even if the opening sealing portion 20 is made to function so as to be prevented from falling off and the connecting portion 22 is omitted in that portion. good.

A ridge or a recess (not shown) may be formed from the end of the mouth portion 11 toward the shoulder portion 12 so that the connecting portion 22 is always attached to the liquid discharge container 30 in the same direction. In this case, it is preferable that the liquid discharge container 30 is formed with the corresponding recesses and ridges.

The structure of attaching the tube container 10 to the liquid discharge container 30 can be variously changed. FIG. 5 is a front view of the tube container 110 according to the modified example, and FIG. 6 is a plan view of the tube container 110 according to the modified example.

The tube container 110 has a head molded body 113 composed of a mouth portion 111 and a shoulder portion 12 connected thereto. The tube container 110 has a body portion 14 connected to the head molded body 113. The tube container 110 has the same configuration as the tube container 10 except that the mouth portion 111 constituting the head molded body 113 is different.

FIG. 7 is a front view of the head molded body 113 according to the modified example. A screw 117 is formed on the head molded body 113 in place of the protrusion 17. The male screw 117 is formed so as to spirally project outward from the outer peripheral surface of the mouth portion 11. As illustrated in FIG. 7, it is sufficient that the male screw 117 is formed around the outer circumference of the mouth portion 11 about once. Although FIG. 7 illustrates a single thread 117, it may be multi-threaded. The head molded body 113 has the same configuration as the head molded body 13 except that it has a male screw 117.

FIG. 8 is a cross-sectional view of the head molded body 113 according to the modified example. The head molded body 113 also has an opening sealing portion 20 that seals the opening 15 integrally molded with the mouth portion 111. The opening sealing portion 20 is formed on the end side of the opening 15 with respect to the male screw 117.

FIG. 9 is an enlarged cross-sectional view of a part of the tube container 110 according to the modified example. Similar to the tube container 10, in the tube container 110, one end of the body portion 14 in which the film-like laminate is formed into a tubular shape is joined to the shoulder portion 12 of the head molded body 113.

Here, the opening sealing portion 20 illustrated in FIGS. 4, 8 and 9 is faced at the end of the opening 15, that is, the end of the mouth 11 and the mouth 111 (hereinafter collectively referred to as the mouth 11). It is also possible to form one. However, when the head molded body 13 and the head molded body 113 (hereinafter collectively referred to as the head molded body 13) are manufactured by compression molding (compression molding), the mold is formed at the end of the mouth portion 11. It will open. Then, a parting line, which is a protrusion generated in the divided line of the mold, is generated at the end of the mouth portion 11, and there is a tendency that burrs are generated and the dimensional accuracy of the molded product is difficult to obtain. Therefore, as illustrated in FIGS. 4 and 8, it is more preferable that the opening sealing portion 20 has a step between the opening and the end of the opening 15.

On the other hand, since the protrusion 17 and the male screw 117 are required to have high accuracy, it is required that the parting line does not straddle. Therefore, the step of the opening sealing portion 20 from the end of the opening 15 is set to a range in which the opening sealing portion 20 and the protrusion 17 and the male screw 117 do not overlap in front view, taking into consideration the thickness of the opening sealing portion 20. Is preferable. In FIGS. 4, 8 and 9, the dividing line 23 of the mold is shown by a chain double-dashed line.

FIG. 10 is an enlarged cross-sectional view of a part of the combination body 1. The liquid discharge container 30 has a mounting portion 40, a connecting flow path portion 50, and a dispenser 60. The mounting portion 40 is provided on the upper side of the connecting flow path portion 50. As illustrated in FIG. 10, the mounting portion 40 is preferably located on the upper surface of the connecting flow path portion 50. The attachment portion 40 is configured to fit into the mouth portion 11 of the tube container 10.

A recess 41 hollowed out in a columnar shape is formed on the upper surface of the connecting flow path portion 50. This recess 41 is the basic structure of the mounting portion 40. At the bottom of the recess 41, an opening 42 communicating with the inside of the connecting flow path portion 50 is formed in a direction of vertically penetrating the connecting flow path portion 50. A mortar-shaped inclined surface 43 may be formed on the upper surface of the connecting flow path portion 50 connected in the outer peripheral direction of the recess 41 so as to correspond to the inclined surface of the shoulder portion 12 of the tube container 10.

FIG. 11 is a cross-sectional view illustrating the fitting state of the tube container 10 and the mounting portion 40. The recess 41 is formed with a protrusion 44 that protrudes inwardly from the inner peripheral surface in an annular shape. The protrusion 44 is composed of a guide surface 45 on the open side of the recess 41 and a return surface 46 on the bottom side of the recess 41. The guide surface 45 is composed of a gentle slope that narrows inside the recess 41 as it approaches the bottom of the recess 41. On the other hand, the return surface 46 is composed of a steep slope that expands to the outside of the recess 41 as it approaches the bottom of the recess 41. The return surface 46 may be perpendicular to the inner peripheral surface of the recess 41.

The protrusion 44 has a shape corresponding to the protrusion 17 of the mouth portion 11 of the tube container 10. The method of attaching the tube container 10 to the attachment portion 40 is a so-called plugging type. That is, the tube container 10 is configured such that the mouth portion 11 is applied so as to cover the recess 41 from above and is pushed downward to fit with the attachment portion 40. The inner and outer circumferences of the protrusion 17 of the tube container 10 and the protrusion 44 of the mounting portion 40 may be opposite to each other.

The protrusion 44 may be configured in a plurality of stages instead of one stage as illustrated in FIG. The protrusion 17 of the tube container 10 and the protrusion 44 of the first stage are fitted to create a state in which the tube container 10 is less likely to wobble, so that the tube container 10 can be pushed into the mounting portion 40 in a more stable state.

When the tube container 10 is mounted on the mounting portion 40, the guide surface 18 of the tube container 10 is configured to slide against the guide surface 45 of the mounting portion 40. Then, when the protrusion 17 of the tube container 10 gets over the protrusion 44 of the mounting portion 40, the return surface 19 of the tube container 10 and the return surface 46 of the mounting portion 40 are in contact with each other. On the other hand, after the tube container 10 is attached to the attachment portion 40, the return surface 19 of the tube container 10 and the return surface 46 of the attachment portion 40 serve as barriers to each other, and the tube container 10 can be easily removed from the attachment portion 40. Is configured so that it will not come off.

However, the tube container 10 is required to be removable from the attachment portion 40 when the contents are empty. Therefore, it is preferable that at least one of the protrusion 17 of the tube container 10 and the protrusion 44 of the mounting portion 40 is made of a flexible or flexible material.

A part of the circumference of the return surface 46 may be formed on a gentle slope. The tube container 10 can be easily removed from the attachment portion 40 by the protrusion 17 of the tube container 10 sliding on the gentle slope portion of the return surface 46. On the upper surface of the connecting flow path portion 50 or the like, which corresponds to the direction opposite to the gentle slope in the circumferential direction of the recess 41, a display indicating the tilting direction when the tube container 10 is removed may be written.

The protrusions 17 and 44 may not be provided in an annular shape over the entire circumference. For example, the tube container 10 has two protrusions 17 facing each other in the radial direction of the mouth portion 11, and each protrusion 17 is formed in a range in which the central angle of the mouth portion 11 is 90 ° or less in a plan view. Is also good. The protrusion 44 may be formed in the same manner as the protrusion 17. With the protrusions 17 and 44 configured in this way, the tube container 10 can be easily removed by rotating the tube container 10 by 90 ° in a plan view.

FIG. 12 is a cross-sectional view illustrating the fitting state of the tube container 110 and the mounting portion 140 according to the modified example. A screw 117 is formed in the tube container 110 in place of the protrusion 17. On the other hand, a female screw 144 is also formed in the mounting portion 140 in place of the protrusion 44. The method of attaching the tube container 110 to the attachment portion 140 is a so-called screw type. The inner and outer circumferences of the screw 117 of the tube container 110 and the female screw 144 of the mounting portion 140 may be reversed.

The screw type configuration with the male screw 117 and the female screw 144 can further reduce the force required for mounting and removing as compared with the plugging type configuration, and further, the tube container 110 is made stronger in the mounting portion 140. Can be fixed.

The liquid discharge container 30 may be fitted to the tube container 10, the tube container 110, or the like by either a plug type such as the attachment portion 40 or a screw type such as the attachment portion 140. However, the liquid discharge container 30 may have a configuration other than the plug-type mounting portion 40 and the screw-type mounting portion 140 as long as the tube container 10 and the tube container 110 can be detachably fixed. ..

The mounting portion 40 and the mounting portion 140 (hereinafter collectively referred to as the mounting portion 40) are protrusions protruding toward the tube container 10 and the tube container 110 (hereinafter collectively referred to as the tube container 10) to be mounted. 47 is provided. The protrusion 47 is configured to adhere to the tube container 10 with airtightness.

The protrusion 47 is formed by the shape of the inner peripheral surface of the mouth portion 11, that is, the shape along the peripheral edge of the opening 15. The normal opening 15 is columnar. Therefore, as illustrated in FIGS. 11 and 12, the protrusion 47 is formed in a cylindrical shape. Then, the combination body 1 is configured such that when the tube container 10 is attached to the attachment portion 40, the inner peripheral surface of the mouth portion 11 and the outer peripheral surface of the protrusion 47 have liquidtightness and adhere to each other. ing. That is, the protrusion 47 has a so-called inner ring function. When the inner and outer circumferences are reversed between the protrusion 17 of the tube container 10 and the screw 117 of the tube container 110 and the protrusion 44 of the mounting portion 40 and the female screw 144 of the mounting portion 140, the protrusion 47 is a so-called It suffices to have the function of an outer ring.

Therefore, when the tube container 10 is attached to the attachment portion 40 or while the liquid discharge container 30 is continuously used, the liquid does not spill from the attachment portion 40, and the outer surface of the liquid discharge container 30 or the operator's hand It does not get dirty by adhering to such things. Then, the liquid discharge container 30 can be used with the tube container 10 attached, and the liquid discharge container 30 and the combination 1 to which the tube container 10 is attached are not bulky.

The protrusion 47 may have a function of breaking the opening sealing portion 20 of the tube container 10. The protrusion 47 is formed in a cylindrical shape cut diagonally. The protruding portion 47 has a protruding top portion 47t that protrudes most and a protruding base portion 47b that does not protrude most on the cut surface cut diagonally. In FIGS. 11 and 12, the protruding top portion 47t is shown on the left side, and the protruding base portion 47b is shown on the right side. The protrusion 47 illustrated in FIGS. 11 and 12 is formed so that the cut surface obliquely cut between the protrusion top 47t and the protrusion base 47b becomes a straight line in a front view. The protruding top 47t has exactly the shape of a blade.

The protruding top portion 47t is configured so that at least the opening sealing portion 20 can be lifted from the mouth portion 11 at the thin wall portion 21 and then lifted to ensure the flow of liquid in the gap between the protruding portion 47 and the opening sealing portion 20. All you need is. If the angle of the end of the protruding top portion 47t is too small, the protruding portion 47 tends to be difficult to lift only by penetrating the opening sealing portion 20. Therefore, the cut surface of the protruding top portion 47t may be formed in a direction substantially perpendicular to the protruding direction of the protruding portion 47, that is, substantially horizontally in front view. By being configured in this way, the protruding top portion 47t can be prevented from penetrating through the opening sealing portion 20 and can transmit a force for efficiently pushing through the opening sealing portion 20, so that the opening sealing portion 20 can be transmitted. Breaking and pushing are more reliable.

The protruding top portion 47t does not penetrate the opening sealing portion 20 when the mouth portion 11 is applied to the recess 41 and the guide surface 18 and the guide surface 45 are in contact with each other, although it depends on the dimensions of the tube container 10. For example, it is preferable that the protrusion length is such that it comes into contact with the opening sealing portion 20. On the other hand, the protruding top portion 47t may have a protruding length that penetrates the initial position of the opening sealing portion 20 when the tube container 10 is attached to the mounting portion 40. With this configuration, the tube container 10 whose contents are sealed is attached to the attachment portion 40 and opened in the initial state. The replacement is completed by one operation of inserting the tube container 10 into the mounting portion 40, and the replacement work can be simplified. Then, when the tube container 10 is attached to the attachment portion 40, the contents do not leak even if the liquid has a low viscosity.

The projecting base portion 47b adheres to the inner peripheral surface of the mouth portion 11 at least on the outer peripheral surface side, and has a projecting length sufficient to realize a sealed state between the liquid discharge container 30 and the tube container 10. I just need to be there. On the contrary, if the protruding base portion 47b is too long, the opening sealing portion 20 is likely to be broken over the entire circumference, which is not preferable. Therefore, it is preferable that the protruding base portion 47b has a protruding length that does not exceed the opening sealing portion 20 in a state where the tube container 10 is attached to the mounting portion 40. As described above, it is preferable that the protrusion 47 is configured to break with the opening sealing portion 20 partially attached to the mouth portion 11. Therefore, it is preferable that the tube container 10 is attached to the liquid discharge container 30 so that the above-mentioned connecting portion 22 is aligned with the position of the protruding base portion 47b.

In the case of a configuration in which the tube container 110 and the mounting portion 140 are fitted by a screw type, for example, instead of the connecting portion 22, the protruding length does not exceed the protruding top portion 47t on the inner peripheral side of the protruding base portion 47b. An unillustrated stick having a sill may be provided. The stick may extend from the mounting portion 40 or may extend from the connecting flow path portion 50 below the mounting portion 40. Like the connecting portion 22, the connecting rod has a function of preventing the broken opening sealing portion 20 from falling off, maintains a connection with the mouth portion 11 of the broken opening sealing portion 20, and does not block the flow of liquid. ..

The protruding base portion 47b and the protruding top portion 47t may be connected in an exponential function rather than in a straight line when viewed from the front, and may be formed substantially horizontally in the vicinity of the protruding base portion 47b. With this configuration, regardless of the state of the broken opening sealing portion 20, a gap is likely to occur between the protruding portion 47 near the protruding base portion 47b and the opening sealing portion 20, and a liquid flow is ensured. can do.

The protruding portion 47 is not limited to the illustrated shape in which the protruding base portion 47b and the protruding top portion 47t are connected by a straight line, and may be formed in a stepped shape, for example. Further, when the opening sealing portion 20 has a form such as a sealing seal having no rigidity, the protrusion 47 does not have a function of breaking the opening sealing portion 20, and the mounting portion 40 is provided with a sealing seal. A pin or the like to break through may be further provided separately. The pin or the like may extend from the mounting portion 40 or may extend from the connecting flow path portion 50 below the mounting portion 40.

The mounting portion 40 may be provided with a contact ring 48 on the outer periphery of the protruding portion 47. As illustrated in FIGS. 11 and 12, the mounting portion 40 includes a contact ring 48 that projects toward the tube container 10 to be mounted. The contact ring 48 is configured to correspond to the shape of the end face of the mouth portion 11. The normal mouth portion 11 has a cylindrical shape. Therefore, the contact ring 48 illustrated in FIGS. 11 and 12 is formed in an annular shape. Then, when the tube container 10 is attached to the attachment portion 40, the end surface of the mouth portion 11 and the protruding surface of the contact ring 48 adhere to the combination body 1, and the inside where the liquid flows and the combination body 1 It is configured to be liquidtight with the outside.

The connection flow path portion 50 is a transport mechanism configured to guide the liquid from the attachment portion 40 to the dispenser 60. The connection flow path portion 50 illustrated in FIG. 1 and the like has a substantially rectangular parallelepiped outer shape, and as shown in FIG. 10, the inside of the cavity is a liquid flow path 51.

The connection flow path portion 50 preferably has a volume for storing a part of the volume of the liquid contained in the tube container 10. Since the tube container 10 is also used as a part of the container in the combination 1, the volume of the connecting flow path portion 50 may be sufficiently smaller than the volume of the liquid contained in the tube container 10. Even if the liquid is still discharged from the liquid discharge container 30 when the contents of the tube container 10 are used up to the end, this volume is removed from the mounting portion 40 for replacement of the tube container 10. The size should be such that the liquid does not leak.

Then, since the connecting flow path portion 50 has a volume for storing a part of the volume of the liquid, a small amount of the liquid remaining in the tube container 10 falls on the connecting flow path portion 50 by its own weight, and the residual liquid in the tube container 10 is collected. Can be reduced. Since the tube container 10 is used while being attached to the liquid discharge container 30, there is sufficient time for the liquid to fall into the connection flow path portion 50, and the residual liquid in the tube container 10 can be effectively reduced. it can.

Further, since the connection flow path portion 50 is configured to have the minimum necessary volume, the liquid discharge container 30 and the combined body 1 to which the tube container 10 is attached are not bulky. Then, the materials and costs required for manufacturing the liquid discharge container 30 can be reduced.

It should be noted that this volume of the connection flow path portion 50 may be formed to be slightly larger. As a result, the replacement time of the tube container 10 can be accelerated. However, even in this case, it is preferable that the volume of the connecting flow path portion 50 is designed to be smaller than the volume of the contents of the tube container 10. By reducing the volume of the connecting flow path portion 50, the flow path 51 becomes shallow, and the remaining amount of liquid can be extremely reduced.

The bottom surface 52 of the flow path 51 is inclined so that the side of the mounting portion 40 is higher and the side of the dispenser 60 is lower in the direction of liquid flow from the mounting portion 40 to the dispenser 60. In FIG. 10, the horizontal line L from the bottom surface 52 on the side of the mounting portion 40 is shown by a chain double-dashed line. A concave pool portion 53 may be provided on the bottom surface 52 of the flow path 51 on the side of the dispenser 60. The flowing liquid finally collects in the lowest pool portion 53 of the bottom surface 52.

A leg portion 54 may be provided on the ground contact surface side of the connection flow path portion 50 in response to the inclination of the bottom surface 52. When the leg portion 54 is provided below the attachment portion 40 or the dispenser 60, it is preferable that the leg portion 54 can support the downward load of the liquid discharge container 30 when the tube container 10 is attached or the liquid is discharged.

FIG. 13 is a sectional view taken along line XIII-XIII of FIG. The bottom surface 52 of the flow path 51 is configured to be lower on the central side in the width direction of the flow. That is, the bottom surface 52 of the flow path 51 has a V-shaped cross section in the width direction of the flow. As a result, the liquid flowing inside the connecting flow path portion 50 collects at the center in the width direction of the flow.

These shapes of the bottom surface 52 are particularly effective when the amount of the liquid introduced into the connecting flow path portion 50 is small or the viscosity of the liquid is low when guiding the liquid from the mounting portion 40 to the dispenser 60. .. Even in such a case, the connection flow path portion 50 can reliably send the liquid to the dispenser 60 so that there is no remaining amount.

At least a part of the connection flow path portion 50 may be made of a transparent material. It is possible to confirm the amount of liquid introduced into the connecting flow path portion 50 through the transparent material. As illustrated in FIG. 1, it is preferable that the window portion 55 made of a transparent material is provided on the outer wall of the connecting flow path portion 50 in the middle of the liquid flowing from the mounting portion 40 toward the dispenser 60. As illustrated in FIG. 10, when the window portion 55 is provided between the position of the opening 42 and the position of the bottom surface 52 in the height direction of the connecting flow path portion 50, the remaining amount of liquid is always visually recognized. It's good to be able to.

The dispenser 60 is a mechanism for discharging (distributing) a liquid. As illustrated in FIG. 1, the dispenser 60 includes a suction pipe 61, a pump 62, a nozzle head 63, a nozzle 64, and the like.

The pump 62 incorporates a valve (not shown) and a compression coil spring (not shown). The nozzle head 63 extends in the vertical direction, and the pump 62 is connected to the lower side. A nozzle 64 extending in the horizontal direction is connected to the upper end of the nozzle head 63. The liquid is configured to pass through the nozzle head 63 and the inside of the nozzle 64.

In the dispenser 60, when the nozzle head 63 is pushed down, the liquid contained in the pump 62 is discharged from the nozzle 64, and when the load on the nozzle head 63 is released, the nozzle head 63 is pushed up by the compression coil spring and the valve opens. The liquid is sucked into the pump 62 through the suction pipe 61.

The pump 62 is not limited to a manual configuration in which the liquid is discharged by pushing down the nozzle head 63, and may be an electric pump.

The dispenser 60 may be directly attached to the connection flow path portion 50. However, as illustrated in FIG. 1, the dispenser 60 is configured such that a tubular container 65 is provided above the upper surface of the connection flow path portion 50, and the nozzle head 63 projects from the upper surface of the container 65. You may have. The container 65 can raise the positions of the nozzle head 63 and the nozzle 64 to make it easier to push down the nozzle head 63 and to easily receive the liquid discharged from the nozzle 64 to improve the workability of the liquid discharge container 30. ..

As illustrated in FIG. 10, the end of the suction pipe 61 is preferably arranged so as to reach the pool portion 53. As a result, the liquid collected in the pool portion 53 can be sucked up without tilting the liquid discharge container 30, and the residual liquid in the connection flow path portion 50 can be further reduced.

The head molded body 13 can be molded so that the mouth portion 11 and the shoulder portion 12 have an appropriate hardness, the body portion 14 has high adhesiveness to the material, and the quality of the contents is not affected. Materials that do not interfere with hygiene even if they come into contact with the contents are used. As such a material, a thermoplastic resin is used for the head molded body 13, and more specifically, high-density polyethylene is used.

Further, the head molded body 13 includes polyolefin resins such as low-density polyethylene, linear low-density polyethylene, medium-density polyethylene, polypropylene (homopolypropylene, block-shaped polypropylene, random polypropylene), olefins, and vinyl-based monomers. Polyolefin-based resins such as acrylic monomers and copolymers with copolymerizable monomers such as unsaturated carboxylic acids and blend compositions thereof, and resins in which the above-mentioned resins are blended with high-density polyethylene are used. Is also good. Further, from the viewpoint of heat resistance and thermal adhesion to the body 14, it is preferable to use a resin in which high-density polyethylene is blended with linear low-density polyethylene for the head molded body 13. Further, the head molded body 13, particularly the shoulder portion 12, may be laminated with a truncated cone-shaped tubular body as a barrier material in order to prevent the permeation of a gas such as oxygen.

The thickness of the head molded body 13 in which such a resin is used is preferably 0.5 mm or more and 1.5 mm or less.

The body portion 14 has flexibility and can maintain independence, has high adhesiveness to the material of the head molded body 13, does not affect the quality of the contents, and is hygienic even if it comes into contact with the contents. A material that does not hinder the use is used. As such a material, a laminate made of a thermoplastic resin is mainly used for the body portion 14, and more specifically, low-density polyethylene, linear low-density polyethylene, or the like is used for the innermost layer in contact with the contents. Low-density polyethylene, linear low-density polyethylene, etc. are used for the outermost layer, and polyethylene terephthalate, aluminum foil, biaxially stretched polyamide, etc., on which aluminum or silicon is deposited, are used for the intermediate layer.

Compression molding (compression molding) and injection molding (injection molding) can be used for manufacturing the head molded body 13. For the production of the body portion 14, a method can be used in which the film-like laminate is rolled into a tubular shape and the overlapping both ends are welded. The body portion 14 may be heat-welded to the preformed head molded body 13, or may be welded at the same time as the head molded body 13 is molded.

In the case of a configuration that does not have the opening sealing portion 20, the head molded body 13 and the body portion 14 may be integrally formed from the viewpoint of simplifying the manufacturing process and speeding up the manufacturing. For example, the head molded body 13 and the body portion 14 may be integrally formed by extrusion blow molding, and then the portion to be the bottom seal portion 16 (see FIG. 2 and the like) may be cut for filling the contents. .. The extrusion blow molding may be a single-layer extrusion blow molding or a laminated extrusion blow molding. In the case of laminated extrusion blow molding, the head molded body 13 and the body portion 14 may have a laminated structure, and for example, a barrier layer may be provided as an intermediate layer.

The contents contained in the tube container 10 can be injected from the lower end of the body portion 14 (see FIG. 2 and the like). The contents of the tube container 10 can be filled with a low-viscosity liquid having sufficiently high fluidity. More specifically, the contents of the tube container 10 include seasonings such as soy sauce, undiluted solutions of diluted beverages, food products such as salad oil, toiletries such as shampoo, cosmetics such as lotion and perfume, and pharmaceuticals such as disinfectant. Can be filled regardless of. The lower end of the body portion 14 of the tube container 10 filled with the contents is heat-sealed to form the bottom seal portion 16 (see FIG. 2 and the like) to obtain a filler.

The liquid discharge container 30 is made of a material that has appropriate rigidity and impact resistance, can be easily molded, and does not hinder hygiene even if it comes into contact with the contents. As such a material, a thermoplastic resin is used for the liquid discharge container 30, and more specifically, polypropylene such as homopolypropylene, block-shaped polypropylene, and random polypropylene, polyethylene, particularly high-density polyethylene and the like are used. The method for manufacturing the liquid discharge container 30 is not particularly limited, but it may be formed by, for example, an injection molding machine.

Next, a method of replacing the tube container 10 will be described in detail.

First, if the overcap is attached to the tube container 10, it is removed. Then, the mouth portion 11 of the tube container 10 is applied to the recess 41 of the liquid discharge container 30. Since the tube container 10 is provided with the opening sealing portion 20, the contents do not spill even when the mouth portion 11 is directed downward.

When the mouth portion 11 and the recess 41 are formed with ridges or ridges that align the directions of the tube container 10, the tube container 10 is rotated so that the ridges and dents mesh with each other. At this point, the guide surface 18 of the protrusion 17 of the tube container 10 and the guide surface 45 of the protrusion 44 of the mounting portion 40 are in contact with each other. On the other hand, no load is still applied to the opening sealing portion 20 of the tube container 10 from the protruding portion 47 of the mounting portion 40.

The tube container 10 is pushed downward. At this time, if the leg portion 54 is provided on the ground contact surface side of the connection flow path portion 50 below the mounting portion 40, the liquid discharge container 30 is not deformed and the tube container 10 is easily pushed in.

The protrusion 17 of the tube container 10 gets over the protrusion 44 of the attachment portion 40, and the protrusion 47 of the attachment portion 40 pushes up the opening sealing portion 20 of the tube container 10 and breaks from the mouth portion 11 at the thin-walled portion 21. The opening 15 of the tube container 10 and the opening 42 of the mounting portion 40 communicate with each other, and the liquid flows down from the broken tube container 10 of the opening sealing portion 20 toward the connecting flow path portion 50 of the liquid discharge container 30. At that time, the outer peripheral surface of the protrusion 47 is maintained in a state of being liquid-tight and adhered to the inner peripheral surface of the mouth portion 11. Therefore, the liquid does not leak from between the tube container 10 and the mounting portion 40 even while the opening sealing portion 20 is being broken.

The return surface 19 of the tube container 10 and the return surface 46 of the attachment portion 40 are in contact with each other in a state of being a barrier, and the tube container 10 is fixed to the attachment portion 40 of the liquid discharge container 30. When the mortar-shaped inclined surface 43 on the upper surface of the connecting flow path portion 50 is formed corresponding to the inclined surface of the shoulder portion 12 of the tube container 10, the tube container 10 becomes more stable and self-supporting.

In the case of the tube container 110, the tube container 110 is rotated with respect to the attachment portion 140, unlike the tube container 10 being pushed downward. In the tube container 110, the operation is the same as in the case of the tube container 10, except that the screw 117 and the female screw 144 are used instead of the protrusion 17 and the protrusion 44.

When it is determined that the tube container 10 or the tube container 110 is empty by visual inspection through the window portion 55 or the like, the tube container 10 or the tube container 110 is removed from the liquid discharge container 30. Since the tube container 10 and the tube container 110 are used while being attached to the liquid discharge container 30, there is sufficient time for the liquid to fall into the connection flow path portion 50, and the tube container 10 and the tube container 110 have almost no residual liquid. Absent. Therefore, the liquid does not spill even when the tube container 10 or the tube container 110 is removed.

Whether it is the tube container 10 or the tube container 110, the replacement is completed by one operation of inserting into the attachment portion 40, and the replacement work is simplified. Therefore, according to the liquid discharge container 30 and the combination 1 according to the present embodiment, it does not take much time and effort to replenish the contents. Further, it is not necessary to remove the portion of the dispenser 60 at the time of replacement, and the outer surface of the liquid discharge container 30 and the hands of the operator are not soiled due to dripping of the liquid or the like. Further, according to the configuration according to the present embodiment, even a person who is not accustomed to the refilling operation can easily complete the refilling work in an extremely short time without spilling the liquid.

As described above, the liquid discharge container 30 according to the present embodiment is attached with the attachment portion 40 that fits with the mouth portion 11 of the tube container 10 by a plug type or a screw type, the dispenser 60 that discharges the liquid, and the liquid. It has a connecting flow path portion 50 that guides the portion 40 to the dispenser 60, and the mounting portion 40 projects toward the tube container 10 to be mounted and provides airtightness with the mouth portion 11 of the tube container 10. It is provided with a protrusion 47 to be held and attached. Further, the combination 1 according to the present embodiment includes the above-mentioned liquid discharge container 30 and the tube container 10. According to the present embodiment, it is possible to simplify the work of replacing the replacement container containing the contents to be replenished, and to provide the liquid discharge container 30 and the combination 1 in which the contents are not spilled and are not bulky.

The present disclosure can be suitably used for a container that discharges a certain amount of liquid. However, the present disclosure is not limited to the embodiments described above. The contents discharged from the liquid discharge container 30 and the combination 1 of the present disclosure are not particularly limited as long as they are liquids having a low viscosity to some extent, and cosmetics such as shampoo, detergents such as liquid detergents and softeners, pharmaceuticals, and miscellaneous goods.
