Description

  The present invention relates to a container body having a mouth tube portion at the top, a cap body assembled to the mouth tube portion of the container body and having a discharge port formed at the upper end thereof, and a content liquid that is attached to and discharged from the cap body The present invention relates to a discharge container composed of a flow regulating body that regulates the flow of the liquid.

  A nozzle with a nozzle-like plug that has a discharge opening at the upper end on the top tube part of the container body, and is attached by urging the nozzle-like plug close to the inner periphery of the nozzle toward the discharge port side of the nozzle There has been proposed a discharge container that includes a member and is provided with a liquid flow path that communicates the upper and lower sides of the rod-shaped plug body at a close contact portion between the rod-shaped plug body outer peripheral portion and the nozzle inner peripheral portion (for example, see Patent Document 1).

  In the discharge container shown in Patent Document 1, for example, the content liquid is pressurized by pressing the body portion of the container body, and discharged from the discharge port through the liquid channel. When the pressure on the body is released, the inside of the container becomes negative due to the elastic restoring force, the rod-like plug body overcomes the urging force and is drawn toward the inside of the container, and the replacement air is introduced from the gap formed on the outer periphery thereof.

JP 2004-331103 A

  In the prior art described in Patent Document 1, a desired regulating force can be applied to the discharged content liquid accurately and reliably, and thereby a stable and smooth discharge operation can be obtained. However, since the liquid flow path that communicates the top and bottom of the rod-shaped plug body is along the discharge direction from the container body to the discharge port, if the content liquid has a low viscosity, a part of the content liquid is scattered at the beginning of the discharge operation. Since there is rarely a case of discharging in the form of a structure, and basically a structure having a check valve with a movable structure having a leak function, high precision is required for molding and assembly of the constituent parts. Manufacturing costs tend to be high and improvements in these respects have been desired.

  Therefore, the present invention was devised to answer the above-mentioned demands in the prior art, and is a technology that regulates the flow of the content liquid and bends its streamline by one member provided in front of the discharge port. Accordingly, it is an object to prevent scattering of the content liquid at the beginning of the discharge operation and to reduce manufacturing costs.

The main structure of the means of the present invention for solving the above problems is as follows.
An open / close cap body that opens and closes the discharge port can be freely attached to and detached from a container body that has a mouth tube portion at the upper end of the body portion and a cap body that is tightly assembled to the mouth tube portion of the container body to form a discharge port. Having an assembled cap body and a flow regulating body mounted in the cap body;
The flow restricting body integrally couples the first restricting plate and the second restricting plate that block the inside of the cap body with a connecting plate at an interval, and the first restricting plate has the first passage hole and the second restricting plate serves as the second restricting plate. Each second passage hole was opened, a flow passage was formed from the first passage hole to the second passage hole through the interval, and the first passage hole and the second passage hole were opened at positions that do not overlap vertically. ,
It is in.

  The flow restricting body mounted in the cap body is positioned between the container body and the discharge port, and the discharged content liquid always passes through the flow restricting body. The flow restricting body is an integrally formed product including a first restricting plate, a second restricting plate, and a connecting plate, and a flow passage extending from the first passage hole to the second passage hole through the interval is formed with the first passage hole. Since the second passage hole is opened at a position where it does not overlap vertically, the passage is bent in a crank shape.

  For this reason, even if the content liquid flows vigorously from the container body side toward the discharge port at the beginning of the discharge operation of the content liquid, it passes through the bent flow passage formed by the flow regulating body, so that the momentum and passage The flow rate is restricted, and it is not discharged in a scattered manner from the discharge port.

  In addition, since the regulating force of the flow regulating body with respect to the content liquid can be determined by the size of the opening diameter and the interval of both passage holes forming the flow path, it is possible to set accurately.

  Furthermore, the flow restrictor has a simple structure in which a pair of restricting plates are simply connected by a connecting plate with a gap between them, and is an integrally molded product having no moving parts, so that the structure and mounting thereof are easy to handle. is there.

  Another configuration of the present invention is obtained by adding the squeeze property to the body portion of the container body to the main configuration described above.

  In the case where the body portion of the container body is provided with squeeze characteristics, the discharge amount of the content liquid can be controlled by a squeeze operation with a fingertip on the body portion. In particular, when the restricting power of the flow restrictor on the content liquid is increased, the flow restrictor functions as a stop valve, so that the content liquid can be semi-forced to pass through the flow restrictor by a squeeze operation. At this time, the discharge amount of the content liquid can be adjusted by adjusting the squeeze operation force. This action is extremely effective for discharging a liquid having a low viscosity.

  According to another configuration of the present invention, a connecting plate is provided in the main configuration described above so as to cross the center of the first and second restricting plates, and the first passage hole is formed on one side with the connecting plate as a boundary. The second passage hole is disposed on the other side, and the flow restrictor is configured by opening the communication hole in the connecting plate.

  In the case where the first passage hole is arranged on one side and the second passage hole is arranged on the other side with the connecting plate as a boundary, and the flow restrictor is configured by opening the connecting hole in the connecting plate, the mechanical strength is A large flow restricting body can be obtained stably, and the connecting plate can also exert a flow restricting action.

  Further, another configuration of the present invention is a configuration in which a connecting plate having a communication hole is added to the main configuration described above, and the first passage hole and the second passage hole are arranged in the direction in which the communication hole is opened. It is added to the fact that it is located diagonally.

  In the case where the first passage hole and the second passage hole are positioned obliquely with respect to the opening direction of the communication hole, the flow line of the content liquid passing through the flow restrictor passes through the communication hole. It will be in the state which bends, and the regulation effect is heightened by that much.

  Another configuration of the present invention is that, in the main configuration described above, each of the first passage hole and the second passage hole is positioned at the opposite peripheral end of the first restriction plate and the second restriction plate. , Is added.

  In the case where the first passage hole and the second passage hole are located at the opposite peripheral end portions of the first restriction plate and the second restriction plate, the distance between the first passage hole and the second passage hole is increased. Accordingly, the flow path length of the content liquid in the flow restricting body becomes longer.

  In addition, another configuration of the present invention is obtained by adding a sub-connecting plate to a part of the side opening portion of the interval to form the flow regulating body in addition to the main configuration described above.

  In the case where the sub-connecting plate is integrally provided on the flow restricting body, it is possible to prevent the article with respect to the interval, for example, the restricting plate of another flow restricting body at the time of assembly or the like from entering in a galling shape.

  In addition, another configuration of the present invention is such that, in the main configuration described above, an elongated cylindrical piece discharge cylinder piece is erected on the upper end of the mounting cylinder piece of the cap body via an inner flange-shaped inner flange wall piece, When the flow restricting body is mounted on the mounting cylinder piece on the upper surface of the second restricting plate of the restricting body, a plurality of abutting pieces that protrude from the lower side against the inner wall piece are protruded so as to avoid the second passage hole. Is added.

  If the cap body is provided with an inner wall piece, and the upper surface of the second restriction plate of the flow restricting body is provided with an abutting piece that abuts against the inner wall piece, the flow restriction against the mounting cylinder piece of the cap body When the body is mounted, the abutting piece abuts against the inner wall piece, so that a space is formed between the flow restricting body and the inner wall piece, and this becomes a flow path. There is no problem with the wall piece.

Since the present invention has the above-described configuration, the following effects can be obtained.
In the main configuration of the discharge container in the present invention, the content liquid is not discharged in a scattered manner from the discharge port, so that the content liquid can be discharged safely and satisfactorily, and a preferable use situation can be obtained. .

  Further, since the flow restricting body is a simple structure and is an integrally molded product having no moving parts, its structure and mounting are easy to handle, so that the manufacturing cost of the entire container can be reduced.

  If the body of the container is squeezed, the discharge amount of the content liquid can be controlled, so that an appropriate amount of the content liquid can be easily discharged. Discharging can be performed easily and accurately.

  In the case where the first passage hole is arranged on one side and the second passage hole is arranged on the other side with the connecting plate as a boundary, and the flow restrictor is configured by opening the connecting hole in the connecting plate, the mechanical strength is A large flow restricting body can be obtained stably, and the connecting plate can also exert a flow restricting action, so that the flow restricting body can be easily handled and has a large flow restricting force.

  In the case where the first passage hole and the second passage hole are located obliquely with respect to the opening direction of the communication hole, the restriction action is enhanced, and the restriction strength can be easily set.

  In the case where the first passage hole and the second passage hole are located at the opposite peripheral ends of the first restriction plate and the second restriction plate, the flow length of the content liquid in the flow restriction body becomes long. Therefore, it is possible to enhance the regulation effect on the content liquid passing therethrough.

  In the case where the sub-connecting plate is integrated with the flow restricting body, for example, when assembling to handle a large number of flow restricting bodies together, the restricting plates of other flow restricting bodies with respect to the interval are prevented from entering in the form of galling. Therefore, it is easy to handle a large number of flow regulating bodies at the same time.

  When the cap body is provided with an inner wall piece, and the upper surface of the second restricting plate of the flow restricting body is provided with an abutting piece that hits the inner wall piece, the opening state of the second passage hole is Since the wall piece does not cause a defect, an efficient assembly process can be obtained.

Embodiments of the present invention will be described below with reference to FIGS.
In this embodiment, the side on which the cap body 5 is located with respect to the container body 1 is the upper side, and the opposite side (the lower side in FIG. 1) is the lower side.

  In FIG. 1, 1 is a container body, 5 is a cap body, 6 is a cap body, 18 is an opening / closing cap body, and 22 is a flow regulating body. The container body 1 has a bottomed cylindrical shape, and a cylindrical mouth tube portion 3 is continuously provided in an upright manner at a top end of a body portion 2 provided with squeezing properties through a shoulder portion that rises with a reduced diameter. It is comprised and is shape | molded with the synthetic resin which has flexibility. The mouth tube portion 3 is provided with a locking protrusion 4 (see FIG. 2) on the outer peripheral surface portion that is an upper portion of the neck ring. The container body 1 contains liquids such as lotions, seasonings, and detergents.

  The cap body 5 (see FIG. 2) includes a cap body 6 that is closely assembled to the mouth tube portion 3 and an opening / closing cap body 18 that opens and closes a discharge port formed by the cap body 6. The cap body 6 includes an assembled cylinder portion 7 that is assembled to the mouth cylinder portion 3, an attachment cylinder portion 12, and a discharge cylinder piece 17.

  The assembled cylinder portion 7 includes a lower skirt cylinder piece 8, a fitting cylinder piece 10 thereon, and a top wall piece 11 provided in an inner flange shape from the upper end of the fitting cylinder piece 10. Yes. The skirt tube piece 8 is provided on the inner peripheral surface thereof with a locking peripheral strip 9 that climbs over the locking protrusion 4 of the mouth tube portion 3 from above and is undercut coupled. Although the fitting cylinder piece 10 is omitted from the drawing so as to be attached to the mouth tube portion 3 so as not to idle, a combination structure of a vertical key and a vertical key groove is provided between the mouth tube portion 3. The combination structure of the vertical key and the vertical key groove is to prevent the cap body 6 from rotating together with the opening / closing cap body 18 when the opening / closing cap body 18 is screwed into / detached from the cap body 6. The top wall piece 11 is in close contact with the upper end surface of the mouth tube portion 3 of the container body 1 to set the assembling limit position, and is tightly fitted into the opening portion of the mouth tube portion 3 from its lower surface. A seal cylinder piece is provided in a hanging shape.

  The mounting cylinder portion 12 includes a lower threaded cylinder piece 13, a mounting cylinder piece 14 thereon, and an inner flange wall piece 16 provided in an inner flange shape from the upper end of the mounting cylinder piece 14. The screwed cylinder piece 13 has engraved screws on its outer peripheral surface for screwing the open / close cap body 18 in a detachable manner. The mounting cylinder piece 14 is provided with a locking ring 15 that locks and holds the flow restricting body 22 at the lower end of the inner peripheral surface. The inner wall piece 16 has a ring disk shape, and the discharge cylinder piece 17 is provided upright and continuously from the inner peripheral edge.

  The discharge cylinder piece 17 is formed in an elongated cylinder shape, and its upper end opening is used as a discharge port. On the outer peripheral edge of this discharge port, a mouthpiece piece that expands in a trumpet shape is provided to improve liquid drainage. It has been.

  The opening / closing cap body 18 (see FIG. 2) is provided with a ceiling wall 20 connected to an upper end of a peripheral wall 19 in which a screw that is detachably screwed to a screw of the threaded cylindrical piece 13 is formed at the lower part of the inner peripheral surface. It has a top cylindrical shape. At the center of the lower surface of the top wall 20, there is a plug piece 21 that tightly fits into the discharge port formed by the discharge cylinder piece 17 in a state in which the opening / closing cap body 18 is screwed to the cap body 6 to seal the container. It is provided in a hanging shape.

  The flow restricting body 22 (see FIGS. 2 and 3) includes a pair of upper and lower first restricting plates 23 and 25, and the first restricting plate 23 and the second restricting plate 25 with an interval K (see FIG. (b) and (c)) are connected to each other and the connecting plate 27 is joined together, and a plurality of abutting pieces 29 are provided on the upper surface of the second restricting plate 25.

  The first restricting plate 23 and the second restricting plate 25 have a disc shape (see FIG. 3A), and in a state where the flow restricting body 22 is mounted in the mounting tube piece 14, the mounting tube piece. 14 is cut off vertically. The connecting plate 27 that connects and couples the first restricting plate 23 and the second restricting plate 25 is located across the center of the first restricting plate 23 and the second restricting plate 25 (see FIG. 3A). )

  The first passage hole 24 opened in the first restriction plate 23 and the second passage hole 26 opened in the second restriction plate 25 are arranged substantially symmetrically on a plane with the connecting plate 27 as a boundary (FIG. 3). (See (a) and (b)). A communication hole 28 is formed at the center of the connecting plate 27, and the first passage hole 24 → the distance K → the communication hole 28 → the distance K → the second passage hole 26 from the inside of the container body 1 through the communication hole 28. Then, a bent flow line R (see FIG. 2) of the discharged content liquid reaching the discharge port of the discharge cylinder piece 17 is obtained. In the flow restricting body 22, the restricting force with respect to the passing content liquid can be set substantially accurately by the dimensions of the first passage hole 24, the interval K, and the second passage hole 26.

  The abutting piece 29 is the one in which the flow restricting body 22 abuts against the inner flange wall piece 16 in a state where the flow restricting body 22 is mounted in the mounting cylinder piece 14 with the first restricting plate 23 locked to the locking ring 15 (FIG. 2), the assembly of the flow restricting body 22 with respect to the mounting cylinder piece 14 is assumed to be free of backlash due to this contact. In addition, a plurality of the abutting pieces 29 are provided at locations avoiding the second passage hole 26 (four in the case of the embodiment shown in FIG. 3A). The abutting piece 29 forms an interval corresponding to the protruding height between the inner collar wall piece 16 and the second restricting plate 25 by abutting against the inner collar wall piece 16. For this reason, even if the second passage hole 26 is located immediately below the inner wall piece 16, the second passage hole 26 is not blocked by the inner wall piece 16. Furthermore, by providing the abutting piece 29, the vertical relationship of the posture of the flow restricting body 22 becomes clear, which makes it easy to handle the flow restricting body 22 during assembly.

  FIG. 4 shows another embodiment of the flow restrictor 22, in which the first passage hole 24 and the second passage hole 26 are positioned obliquely with respect to the opening direction of the communication hole 28 and the first restriction The plate 23 and the second restricting plate 25 are positioned at the opposite peripheral ends. In this embodiment, when the flow line R of the content liquid passes through the communication hole 28, it is bent and the distance between the first passage hole 24 and the second passage hole 26 is increased, so that a large restricting action is achieved. Will be demonstrated.

  FIG. 5 shows still another embodiment of the flow restricting body 22, in which a sub-connecting plate 27a is integrally provided in a part of the side opening portion of the interval K, and the sub-connecting plate 27a has an interval K. By being positioned at a part of the side opening portion, it is possible to prevent another article, for example, a restriction plate of another flow restricting body 22 from entering the gap K in a galling manner. The sub-regulatory plate 27a is provided at a position close to the center in a posture substantially orthogonal to both sides with respect to the connecting plate 27. Since the sub-connecting plate 27a fills the interval K and connects the first restricting plate 23 and the second restricting plate 25, the mechanical strength of the flow restricting body 22 having the interval K is increased.

  Next, the content liquid discharge operation will be described. When the container is turned upside down, the content liquid flows down vigorously from the container body 1 to the cap body 6 by its own weight. The content liquid that has flowed down vigorously hits the first restriction plate 23 of the flow restrictor 22 and reaches the discharge port through the first passage hole 24 and the flow path indicated by the flow line R. The flow control action of 22 eliminates momentum. For this reason, scattering of the content liquid at the beginning of discharge is reliably prevented.

  Further, if the restricting force of the flow restricting body 22 with respect to the passing content liquid is increased, the flow restricting body 22 functions as a stop valve. Therefore, if the body 2 is squeezed and deformed in this state, the squeeze of the body 2 is squeezed. The discharge of the content liquid can be controlled according to the pressure action accompanying the operation. When the viscosity of the content liquid is low, a large operating force is not required for the squeeze deformation of the body portion 2, which is particularly effective.

  As described above, the configuration and the operation effect of the present invention have been described according to the embodiment. However, the embodiment of the present invention is not limited to the above embodiment. For example, the communication hole 28 has a structure opened in the connection plate 27, but the connection plate 27 is divided into a plurality of parts, and the first passage hole 24 and the second passage hole 26 are passed through the interval K between the connection plates 27. Can be communicated. In addition, the first passage hole 24 and the second passage hole 26 are disposed substantially symmetrically with the connection plate 27 as a boundary, but may be asymmetric or disposed regardless of the connection plate 27. Furthermore, the assembled structure of the cap body 6 with respect to the mouth tube portion 3 and the assembled structure of the opening / closing cap 18 with respect to the cap body 6 can be unified to either one even if the structure is changed.

  The discharge container of the present invention is configured to bend the flow line of the discharged content liquid, thereby causing a flow regulating force to act on the discharged content liquid, and preventing the content liquid from being vigorously discharged. The content liquid can be discharged safely and can be applied in a wide range of fields as a discharge container.
