Description

  The present invention relates to a squeeze container cap, and more particularly to a squeeze container cap that is used by being attached to a mouth portion of a container body made of plastic that can be squeezed.

  The squeeze container is a container that deforms the container body by squeezing (squeezing) the body of the container body by hand, and discharges a predetermined amount of liquid from the discharge port toward the discharge location. A squeeze container is usually used with a cap having a discharge port detachably attached to the neck of a container body made of plastic that can be squeezed so that the content liquid can be replenished or replaced. In such a squeeze container, for example, after removing the outer lid that covers the discharge port, the content liquid is obtained by squeezing the container body in a state in which the gripped squeeze container is tilted or inverted and the discharge port faces the discharge point. Is discharged by a predetermined amount.

  In addition, when the squeezed container is released from the squeezed state, the deformation of the container body is restored and the inside becomes negative pressure. Can be pulled back into the body.

  On the other hand, in the case of a squeeze container, if the body part of the container body is gripped and tilted or inverted, the content liquid may leak from the discharge port due to the internal pressure of the container body or the weight of the content liquid without squeezing the container body. There may be dripping. Such unexpected leakage or dripping of the liquid content causes the appearance of the squeeze container and the hand during use, and various techniques have been developed to prevent them (for example, Patent Document 1, Patent Document 2, and Patent Document 3).

JP 2006-219181 A JP 2003-226377 A JP 2005-82233 A

  In Patent Document 1, the dip tube communicating with the discharge port of the cap is curved in a U shape, and the liquid inlet is disposed in the vicinity of the discharge port, so that the content liquid is not discharged from the discharge port unless the container body is squeezed. In this way, unnecessary liquid dripping can be effectively avoided. However, the U-shaped curved tube structure is inconvenient to handle when attaching and detaching the cap, and when squeezed with the content liquid remaining inside the dip tube, the air may bite and the liquid may scatter around . In Patent Document 2, a bottomed cylindrical trap room is fixed on the lower side of the spout part, and a communication hole is provided in the peripheral wall and bottom of the bottomed cylinder, so that the liquid remaining in the trap room Is returned to the container to prevent dripping. However, if the liquid does not accumulate to some extent in the trap room, the liquid cannot be poured out. This causes problems such as a decrease in the discharge amount and an inability to adjust in the first time. Furthermore, in the cited document 3, when the content liquid is a liquid having a viscosity as low as that of water or ethanol, it is prevented that it is discharged sensitively in response to a pressure change when the container body is pressed. For this purpose, a narrow groove extending in a bent manner is formed on the inner peripheral surface of the cylindrical fitting portion of the nozzle body or on the outer peripheral surface of the inner plug fitted to the cylindrical fitting portion. The content liquid is fed into the liquid storage space held between the upper surface of the inner plug and the lower surface of the top plate of the nozzle body through the flow path formed by the narrow groove, and is discharged through the nozzle portion of the nozzle body. It is like that. This nozzle body can easily form a flow path by a narrow groove that bends and extends simply by fitting an inner plug to the cylindrical fitting portion of the nozzle body, and from a liquid pool space of a considerable size. Since the liquid is discharged, it is effective when it is provided in a constant pressure amount eye drop container or the like. However, the nozzle body of the cited document 3 also has a liquid pool space between the outflow opening of the nozzle section and the inner plug, so that the liquid is not sufficiently drawn by the back suction or the content in the liquid pool space. When squeezing with the liquid remaining, there is a problem that air is bitten.

  The present invention can effectively avoid leakage and dripping of the content liquid before squeezing, regardless of the viscosity of the content, and can stabilize the discharge amount and obtain good liquid drainage with a simple configuration. An object of the present invention is to provide a cap for a squeeze container.

  The present invention is a squeeze container cap that is used by being attached to a mouth part of a container body made of squeeze-deformable plastic, and discharges the content liquid from the discharge port at the tip by squeeze deformation of the body part of the container body, The lower surface of the top surface portion is attached by attaching the mounting member so as to be close to the lower surface of the top surface portion in which the outflow opening to the discharge port of the cap is formed or in close contact with the lower surface of the top surface portion. An extended flow path extending along the throat is formed, the extended flow path communicates with the outflow opening of the top surface portion, and the mouth portion of the container body through the inflow port formed in the mounting member The above object is achieved by providing a cap for a squeeze container that communicates with the squeeze container.

  According to the squeeze container cap of the present invention, it is possible to effectively avoid leakage and dripping of the content liquid before squeezing with a simple configuration, and it is possible to obtain a stable discharge amount and good liquid drainage. .

  The present invention will be described below based on preferred embodiments with reference to the drawings. FIG. 1 shows a squeeze container 11 with a squeeze container cap 10 according to a preferred first embodiment of the present invention. As shown in FIG. 1, the squeeze container cap 10 is used by being attached to a mouth part 12 a of a container body 12 made of plastic that can be squeezed. The squeeze container cap 10 has a nozzle portion 19 having a discharge port 13a formed at the tip, and the user holds the body portion 12b of the container body 12 to tilt or invert the squeeze container 11. After the discharge port 13a at the tip of the nozzle portion 19 is directed to the discharge location, the body portion 12b of the container body 12 is squeezed (squeezed) to deform the container body 12, whereby the liquid content is transferred from the body portion 12b to the mouth neck portion 12a. The squeeze container cap 10 is fed to the nozzle portion 19 through the discharge port 13a so that a predetermined amount can be discharged. Further, the squeeze container cap 10 is configured so that the content liquid is not subjected to the internal pressure of the container body 12 or the content liquid until the body part 12b of the container body 12 is squeezed after the discharge port 13a of the nozzle part 19 is directed to the discharge location. It is provided with a function capable of avoiding leakage or dripping from the discharge port 13a due to its own weight.

  That is, the squeeze container cap 10 according to the first embodiment is used by being attached to the mouth part 12a of the container body 12 made of squeeze-deformable plastic. It is a cap that discharges the content liquid from the outlet 13a. The squeeze container cap 10 is fitted with a mounting board 17 as a mounting member in close contact with the lower surface of the top surface portion 10a in which the outflow opening 15 to the discharge port 13a of the cap 10 is formed. An extended flow path 14 extending along the lower surface of the top surface portion 10a is formed in a close contact portion between the 10a and the mounting board 17. The extension flow path 14 communicates with the outflow opening 15 of the top surface portion 10a and also communicates with the mouth portion 12a of the container body 12 via the inflow port 18 (see FIG. 2B) formed in the mounting board 17. It is like that.

  In the first embodiment, as shown in FIGS. 2A and 2B, the mounting groove 16 connected to the inlet 18 is formed along the upper surface of the mounting board 17. Since the mounting board 17 is fitted so that the concave groove 16 is connected to the outflow opening 15 of the top surface portion 10a, the extension groove 14 extending from the inflow port 18 to the outflow opening 15 is formed by the mounting concave groove 16. Yes.

  Furthermore, in the first embodiment, the bottom surface portion 14 a of the extension flow path 14 has a downward slope from the outflow opening 15 toward the inflow port 18 in the upright state of the squeeze container 11. Here, the downward gradient may be such that the bottom surface portion 14a of the extension flow path 14 has a substantially downward gradient in the entire flow path, or a substantially horizontal gradient. Moreover, a horizontal part may be mixed in the middle. Further, the entire bottom surface portion 14a of the extension flow path 14 may be substantially parallel (substantially horizontal) as long as the content liquid can be collected in the container body 12.

  The content liquid that can be accommodated in the container body 12 includes a liquid composition that is measured and used, and examples thereof include a liquid cleaning agent for clothing, a softening agent, a bleaching agent, and a liquid bath agent. Moreover, liquid foodstuffs, such as cooking oil and a seasoning, may be sufficient.

  In the first embodiment, the container body 12 is a flexible bottle-shaped plastic container that can be deformed by squeeze, and as shown in FIG. It consists of a mouth part 12a formed so as to protrude upward from the upper end part of 12b and having an upper end serving as an opening surface. A squeeze container cap 10 is detachably attached to the mouth portion 12a through various known screwing means and fitting means. Moreover, the container main body 12 can be easily formed using, for example, various known synthetic resins by, for example, blow molding.

  The squeeze container cap 10 is, for example, a plastic molded product, and includes a circular top surface portion 10a and an annular skirt-shaped peripheral wall portion 10b integrally extending downward from the peripheral portion of the top surface portion 10a. . A nozzle portion 19 is provided on the top surface portion 10a so as to protrude upward from the peripheral portion of the outflow opening 15 at the center portion thereof. The nozzle portion 19 includes a cylindrical intermediate portion 19b standing from the top surface portion 10a, and a nozzle body 19a fixed to the tip portion of the cylindrical intermediate portion 19b. Further, a discharge flow path 13 is formed that penetrates the cylindrical intermediate portion 19b of the nozzle portion 19 and the nozzle body 19a in the vertical direction and extends from the outflow opening 15 to the discharge port 13a. A cover body 21 that covers the discharge port 13 a at the tip of the nozzle body 19 a so as to be openable and closable is joined to the nozzle portion 19, and the discharge port 13 a can be sealed when the squeeze container 11 is stored.

  Further, the annular skirt-shaped peripheral wall portion 10b is provided with, for example, a female screw on the inner surface of the substantially lower half portion, and this female screw is provided on the outer peripheral surface of the mouth portion 12a of the container body 12, for example. By being fastened to the male screw, the cap 10 is detachably attached to the mouth portion 12a. Furthermore, an annular mounting protrusion 20 that protrudes downward from the lower surface of the top surface portion 10a is provided inside the peripheral wall portion 10b. The mounting board 17 is fitted upward inside the annular mounting protrusion 20, and for example, the peripheral corner of the lower surface of the mounting board 17 is locked to a locking rib 20 a provided on the inner surface of the lower end of the annular mounting protrusion 20. Thus, the mounting plate 17 is fixed to the inside of the cap 10 in a state in which the outflow opening 15 is covered from below and the upper surface thereof is overlapped and adhered to the lower surface of the top surface portion 10a.

  The mounting board 17 is a molded product made of plastic, for example, and has a circular drum shape as shown in FIGS. 2 (a) and 2 (b). Further, in the mounting board 17, the mounting groove 16 extending spirally from the peripheral part of the mounting board 17 toward the center part along the upper surface thereof has a rectangular or substantially rectangular cross-sectional shape. Is formed as a spiral groove. An inlet 18 is formed through the end of the peripheral edge of the mounting groove 16.

  Here, the mounting groove 16 extending in a spiral shape has a bottom surface that smoothly and continuously increases from the peripheral portion of the mounting plate 17 that is the starting end portion toward the central portion of the mounting plate 17 that is the terminal portion. Ascending slope increases. Due to the ascending slope of the mounting groove 16, the spiral extension flow path 14 formed in the close contact portion between the lower surface of the top surface portion 10 a of the cap 10 and the upper surface of the mounting board 17 by the mounting groove 16 has a bottom surface portion. When the squeeze container 11 is in an upright state, 14a forms a downward slope that continuously inclines from the central portion serving as the upper end of the mounting groove 16 toward the body 12b of the container body 12. Since the bottom surface portion 14a of the extension channel 14 has a downward slope toward the trunk portion 12b of the container body 12, when the squeeze container 11 is brought into an upright state after use, the inner portion remaining in the extension channel 14 The solution can be discharged to the container body 12 more smoothly.

  Further, the upper end portion of the mounting groove 16 extending in a spiral shape opens at the central portion of the upper surface of the mounting board 17 and is disposed at a portion immediately below the outflow opening 15 of the top surface portion 10a of the cap 10 so as to be mounted. The concave groove 16 communicates with the outflow opening 15 at the upper end portion. On the other hand, the lower end portion of the mounting groove 16 disposed in the peripheral portion of the mounting board 17 communicates with the mouth portion 12 a of the container body 12 through the inlet 18.

  According to the squeeze container cap 10 of the first embodiment having the above-described configuration, it is possible to effectively avoid leakage and dripping of the content liquid before squeezing with a simple configuration and to stabilize the discharge amount. And good liquid drainage can be obtained.

  That is, according to the squeeze container cap 10 of the first embodiment, the mouth of the container main body 12 can be formed with a simple configuration in which the mounting board 17 is fitted in close contact with the lower surface of the top surface portion 10a of the cap 10. The extension flow path 14 for extending the flow path from the neck portion 12a to the discharge port 13a at the tip of the nozzle portion 19 is compactly formed inside the cap 10 by the mounting concave groove 16 without overlapping the flow paths in the vertical direction. It becomes possible to form.

  Further, since the extension channel 14 is formed by the mounting groove 16, when the squeeze container 11 is tilted or inverted in order to discharge the content liquid, the content liquid is transferred by the mounting groove 16 of the mounting board 17. After passing through the extended flow path 14 that is bent and extended in a spiral shape, it is discharged from the discharge port 13a. Accordingly, not only is the content liquid smoothly discharged from the discharge port 13a through the extension flow path 14, but the content liquid requires a certain amount of time to pass through the extension flow path 14 that is bent and extended. While the content liquid is being discharged, that is, while the content liquid is passing through the extension flow path 14, the content liquid is in contact with the entire wall surface of the extension flow path 14. Thus, it becomes difficult for air to be displaced into the extension flow path 14 through the line 13, and the content liquid can be held in the extension flow path 14 for a long time. Further, since the content liquid passes through the extension flow path while contacting the wall surface during squeeze discharge, friction due to contact is generated and the retention effect in the flow path can be enhanced. By these, after the squeeze container 11 is tilted or inverted and the discharge port 13a is directed to the discharge location, the content liquid is discharged by the internal pressure or the own weight of the container body 12 until the body 12b of the container body 12 is squeezed. It is possible to effectively avoid leakage from the outlet 13a or dripping, and to stabilize the discharge amount.

  Furthermore, since the leakage and dripping of the content liquid before squeezing the trunk portion 12b can be effectively avoided as described above, it is possible to obtain a good drainage due to the back suction of the content liquid when the squeezed state is released. Is possible. Such a liquid break due to back suction causes the volume of the trunk 12b due to deformation of the container main body 12 when the volume of the extension flow path 14 bent in a spiral shape by the mounting concave groove 16 is squeezed. By making it smaller than the amount of decrease, it becomes possible to obtain a better liquid draining effect.

  Furthermore, according to the squeeze container cap 10 of the first embodiment, the bottom surface portion 14 a of the extension flow path 14 that is bent and extended by the spiral mounting groove 16 of the mounting board 17 is formed upright on the squeeze container 11. Since the squeeze container 11 is placed in an upright state after use, for example, if the squeeze container 11 is placed in an upright state after use, the content liquid remains in the extension channel 14. Even in the case, the remaining content liquid flows down by its own weight along the descending slope of the bottom surface portion 14 a and is smoothly collected in the body portion 12 b of the container body 12. Thus, when the container body 12 is gripped and the body 12b is squeezed when the next squeeze container 11 is used, the content liquid is not left in the extended flow path 14 by the mounting groove 16 of the mounting board 17. Therefore, it is possible to effectively avoid the scattering of the content liquid due to the air biting of the content liquid.

  In the first embodiment, since it is not necessary to reduce the cross-sectional areas of the discharge port 13a and the extension flow path 14, it is effective to increase the squeeze pressure when squeezing the body 12b of the container body 12. Can be avoided. Further, the cap 10 and the mounting board 17 can be easily manufactured as simple and compact parts, and the extension flow path 14 by the mounting groove 16 of the mounting board 17 is formed compact without overlapping in the vertical direction. Therefore, the remaining amount of the content liquid collected in the container main body 12 can be reduced.

  FIG. 3 shows a squeeze container cap 22 according to a preferred second embodiment of the present invention mounted on the mouth portion 12a of the container body 12 similar to the first embodiment. The squeeze container cap 22 of the second embodiment has substantially the same configuration as the squeeze container cap 10 of the first embodiment. In the squeeze container cap 20 of the second embodiment, the concave groove of the extension channel is formed in the mounting board 17 in the squeeze container cap 10 of the first embodiment, whereas the top surface portion 22a of the cap 20 is. It differs in that it is formed. That is, in the squeeze container cap 22 of the second embodiment, the top surface groove 23 connected to the outflow opening 15 ′ is formed along the bottom surface of the top surface portion 22a, and the top surface groove 23 is mounted on the mounting board ( The mounting plate 24 is fitted so as to be connected to the inlet 18 ′ formed in the mounting member 24, so that the extended flow path 14 ′ from the inlet 18 ′ to the outlet 15 ′ is formed by the top groove 23. It is supposed to be formed.

  In the second embodiment, the top groove 23 formed along the bottom surface of the top surface portion 22a is formed from the peripheral portion of the top surface portion 22a to the central portion, like the mounting groove 16 of the first embodiment. The spiral groove extending in a spiral shape is cut out so as to have a rectangular or substantially rectangular cross-sectional shape. The top groove 23 is connected to the outflow opening 15 'of the top surface 22a at the end of the spiral central portion, and is attached to the bottom surface of the top surface 22a at the end of the peripheral portion. Connected to the inlet 18 'of the mounting board 24 to be mounted.

  The mounting board 24 is a molded product made of plastic, for example, and has a circular drum shape, like the mounting board 17 of the first embodiment. In the second embodiment, the mounting board 24 is not formed with a concave groove, and the upper surface and the lower surface thereof are both flat surfaces. In the peripheral portion of the mounting board 17, an inflow port 18 ′ is formed at one location at a position corresponding to the end portion of the peripheral portion of the top surface concave groove 23. In addition, since the upper surface of the mounting board 24 is a flat surface, the bottom surface 14a ′ of the extension flow path 14 ′ by the top groove 23 becomes horizontal (substantially horizontal), but the extension flow path 14 ′. Even if the bottom surface 14a ′ of the liquid crystal is horizontal (substantially horizontal), the overall gradient is not reverse, so that the function of collecting the content liquid remaining in the extension flow path 14 ′ in the container body 12 can be sufficiently exerted. Become.

  The mounting plate 24 is fitted inside the annular mounting projection 20 provided on the lower surface of the top surface portion 22a and locked to a locking rib 20a provided on the inner surface of the lower end of the annular mounting projection 20, for example. 24 is fixed to the inside of the cap 22 in a state where the top surface concave groove 23 is covered from below and the upper surface thereof is in close contact with the lower surface of the top surface portion 22a. As a result, a spiral extension channel extending from the inlet 18 ′ to the outlet opening 15 ′ along the lower surface of the top surface portion 22 a is in contact with the lower surface of the top surface portion 22 a of the cap 22 and the upper surface of the mounting board 24. 14 ′ is formed by the top groove 23.

  Also with the squeeze container cap 22 of the second embodiment, the bottom surface 14a 'is a horizontal extension flow with a simple configuration in which the mounting board 24 is fitted in close contact with the lower surface of the top surface portion 22a of the cap 22. The passage 14 'can be easily formed, and the content liquid is discharged from the discharge port 13a via the extension flow passage 14', thereby providing the same operational effects as the first embodiment. Become.

  FIG. 4 shows a squeeze container cap 25 according to a preferred third embodiment of the present invention in a state where the squeeze container cap 25 is attached to the mouth portion 12a of the container body 12 similar to the first embodiment. The squeeze container cap 25 of the third embodiment has substantially the same configuration as the squeeze container cap 10 of the first embodiment. In the squeeze container cap 25 of the third embodiment, the recessed groove of the extension channel is formed in the mounting board 17 in the squeeze container cap 10 of the first embodiment, whereas the top surface portion 25a of the cap 25 is It differs in that it is formed on both the mounting board (mounting member) 28. That is, in the squeeze container cap 25 of the third embodiment, the top groove 26 connected to the outflow opening 15 "is formed along the lower surface of the top surface portion 25a, and the squeeze container cap 25 is connected to the inlet 18". A concave groove 27 is formed along the upper surface of the mounting board 28 in a shape matching the top surface concave groove 26. By fitting the mounting board 28 so that the top groove 26 and the mounting groove 27 overlap, the overlapping top surface groove 26 and mounting groove 27 allow the inlet 18 "to the outlet 15". An extended flow path 14 ″ is formed.

  In the third embodiment, the top surface groove 26 formed along the bottom surface of the top surface portion 25a is similar to the top surface groove 23 of the second embodiment, from the peripheral portion to the center portion of the top surface portion 25a. As a spiral groove extending in a spiral shape toward the surface, it is cut out so as to have a rectangular or substantially rectangular cross-sectional shape. The top surface concave groove 26 is connected to the outflow opening 15 ″ of the top surface portion 25a at the end of the spiral central portion.

  Moreover, the mounting board 28 is a plastic molded product, for example, and has a circular drum shape, like the mounting board 17 of the first embodiment. In the third embodiment, the mounting board 28 has a rectangular or substantially rectangular mounting groove 27 extending in a spiral shape from the peripheral part of the mounting board 28 toward the center along the upper surface thereof. It is cut out so as to have a cross-sectional shape, and is provided as a spiral groove. An inlet 18 ″ is formed through the end of the peripheral edge of the mounting groove 27.

  Here, the mounting groove 27 extending in a spiral shape has a bottom surface that smoothly and continuously increases from the peripheral portion of the mounting plate 28 that is the starting end portion toward the central portion of the mounting plate 28 that is the terminal portion. Ascending slope increases. Due to the ascending slope of the mounting groove 27, the spiral extension channel 14 ″ formed in the close contact portion between the mounting board 28 and the top surface portion 25 a of the cap 25 by the mounting groove 27 and the top surface groove 26, The bottom surface portion 14 a ″ forms a downward slope that continuously inclines from the central portion serving as the upper end portion of the mounting groove 27 toward the body portion 12 b of the container body 12 in the upright state of the squeeze container 11. Become.

  The mounting board 28 is fitted inside the annular mounting protrusion 20 provided on the lower surface of the top surface portion 25a and locked to a locking rib 20a provided on the inner surface of the lower end of the annular mounting protrusion 20, for example. 28, while covering the top surface portion 25a from below and arranging the mounting groove 27 so as to overlap the top surface groove 26 of the top surface portion 25a, the top surface thereof is in close contact with the bottom surface of the top surface portion 22a, The cap 25 is fixed inside. As a result, a spiral extension channel extending from the inlet 18 ″ to the outlet 15 ″ along the lower surface of the top surface portion 25a is in close contact with the lower surface of the top surface portion 25a of the cap 25 and the upper surface of the mounting board 28. 14 ″ is formed by the overlapping top groove 26 and mounting groove 27.

  Also with the squeeze container cap 25 of the third embodiment, the bottom surface 14a "has a downward slope by a simple configuration in which the mounting board 28 is overlapped and fitted in close contact with the lower surface of the top surface portion 25a of the cap 25. The extension channel 14 ″ can be easily formed, and the content liquid is discharged from the discharge port 13a via the extension channel 14 ″, so that the same effect as that of the first embodiment can be obtained. Will play.

  In the squeeze container caps 10, 22, and 25 of the first embodiment, the second embodiment, and the third embodiment, there are various extension channels formed by the mounting grooves and the top groove. It may be extended to the shape. Moreover, the connection part to the outflow opening of the top | upper surface part of the caps 10, 22, and 25 does not necessarily need to be the center part of the mounting board which is a top | upper surface part or a mounting member, and an inflow port is provided in two or more places in a mounting | wearing board. You can also.

  For example, as the swirling pattern of the extension flow path 30, an arc-shaped extension flow path 30 and one inflow port 31 as shown in FIGS. 5A and 5B can be adopted. As shown in FIGS. 6A and 6B, it is possible to employ a bent linear extension flow path 30 and one inflow port 31. As shown in FIGS. 7A and 7B, it is also possible to employ an extended flow path 30 in which an arcuate portion and a linear portion are combined and one inflow port 31. As shown in FIGS. 8 (a) and 8 (b), an arc-shaped extended flow path 30 and a plurality of inlets 31 may be employed. Further, as shown in FIGS. 9 (a) and 9 (b), the connection portion b with the outflow opening of the top surface portion is not the top surface portion or the central portion of the mounting plate, or the connection portion a with the inlet of the mounting plate is It is also possible to adopt the top surface part or the central part of the mounting board. In each figure, the symbol “a” indicates a connection portion with the inflow port of the mounting board, and the symbol “b” indicates a connection portion with the outflow opening of the top surface portion.
