Description

  The present invention relates to a protective cover attached to a pump container and a pump container provided with the protective cover.

  As a pump container filled with a liquid such as a hair shampoo and a body soap, there is one constituted by a container body and a cap means that is provided at the mouth of the container body and includes a cap and a pump mechanism. The pump mechanism enables the liquid sucked into the cylinder to be discharged from the nozzle discharge port of the pump head by the vertical movement of the piston.

  A pump container having such a pump mechanism is very convenient because an appropriate amount of liquid in the container body can be taken out by simply pushing the pump head by hand. It may be discharged.

  Technologies that can prevent this erroneous operation are disclosed in Patent Documents 1 to 4.

  Patent Document 1 describes a stopper that is interposed between a pump head and a cap and restricts the pump head from being pressed down.

  Patent Document 2 describes a head cover that is mounted so as to be covered from above the pump head and restricts the pump head from being pressed down.

  In Patent Document 3, a cap body, a nozzle storage cylinder, and a cap top wall are provided, and the lower end of the cap body is made freely contactable with the upper surface of the guide cylinder, thereby restricting the pressing of the pressing head with nozzle. A cover cap is described.

  Patent Document 4 describes a cover that regulates the depression of the depression head by bringing the lower end surface of the stem covering portion hanging from the lower end of the head covering portion into contact with the upper surface of the stem retaining cylinder. .

JP 2001-180774 A (refer to claim 1) JP-A-8-175558 (see paragraphs 0016 and 0018) JP-A-10-263443 (see paragraph 0016) Japanese Patent Laying-Open No. 2003-104415 (see paragraph 0012)

  For pump containers that allow the contents of the container body to be discharged from the nozzles of the pump head by moving the pump head up and down, it is necessary to prevent erroneous operation of the pump head not only after the start of use but also during transport at the time of shipment. There is. Any of the techniques described in Patent Documents 1 to 4 can prevent an erroneous operation of the pump head. However, none of them can be mounted in the downward movement position of the pump head, and since the pump head is in the upward movement position located at the upper limit, the extension of the pump head is bulky and not suitable for conveyance. .

  In addition, if the pump container can be fixed in the downward movement position where the pump head is located at the lower limit, the pump head is maintained in the downward movement position, so that the contents can be dispensed and not bulky. However, once the pump head is brought into the up-motion position in order to start use, even if the pump head is returned to the down-motion position again, the content of one push is discharged and wasted. For this reason, a stopper for preventing an erroneous operation in the upward movement posture of the pump head must be prepared separately.

  Therefore, in view of the above, the present invention provides a protective cover that can be attached to the pump container even in the downward movement position while preventing the pump head from being erroneously operated in the upward movement position, and a pump container using the protective cover. It is intended.

  In order to achieve the above object, the protective cover of the present invention has the following configuration. That is, the pump mechanism that can discharge the contents of the container main body from the nozzle of the pump head by the vertical movement of the pump head and can maintain the pump head in the downward movement position via a cap that is screwed into the mouth of the container main body. In the protective cover of the pump container mounted on the container body, the protective cover is provided with a regulating means for restricting the pump head to be pushed down in the upwardly moving posture of the pump head. A protective cover having a cap holding portion fitted to a cap and / or a head holding portion fitted to a pump head.

  Since the restricting means restricts the pump head from being pushed down, erroneous operation of the pump head can be prevented. In addition, since the pump head has a cap holding portion fitted to the cap and / or a head holding portion fitted to the pump head in the downward movement posture, the protective cover can be attached to the pump container even in the downward movement posture. Can do.

  As a mode in which the regulating means regulates the depression of the pump head, in the upward movement posture of the pump head, (1) the top surface side of the pump head is covered and the lower end thereof is used as the top surface of the cap or part of the pump mechanism. The pump head may be configured to cover the pump head, or (2) a stopper is interposed between the pump head and the top surface of the cap or a part of the pump mechanism, and the lower surface of the pump head and the cap It is good also as a form contact | abutted to a top surface or a part of pump mechanism. In addition, as a part of pump mechanism, if it is located below a pump head among the members which comprise a pump mechanism, it will not be limited.

  Specifically, with regard to the former mode (1), the regulating means includes an upper wall that covers the top surface side of the pump head, and a cap holding portion that is fitted to the cap in a downward movement posture of the pump head, and the pump head The lower end of the cap holding part may be brought into contact with the top surface of the cap or a part of the pump mechanism in the upward movement posture. Even if the pump head is accidentally pushed from above the upper wall, the cap holding portion comes into contact with the top surface of the cap or a part of the pump mechanism, so that the pump head can be restricted from being pushed down.

  Alternatively, the restricting means includes an upper wall that covers the top side of the pump head, a cap holding portion that is fitted to the cap in a downward movement posture of the pump head, and a restriction wall that protrudes inward from the lower end of the cap holding portion. The regulating wall may be brought into contact with the top surface of the cap or a part of the pump mechanism in the upwardly moving posture of the pump head. Even if the pump head is accidentally pushed from above the upper wall, the regulating wall comes into contact with the top surface of the cap, so that the pump head cannot be pushed down any further. In addition, if a restriction wall is provided, the protective cover can be stably attached and effectively prevented from falling off if the restriction wall is locked to the lower edge of the cap when the pump head is lowered. Can do. Specifically, for example, as shown in FIGS. 5 and 6, the distance L1 between the upper wall and the regulating wall of the protective cover, and the length L2 from the upper end of the pump head to the lower end of the cap when the pump head is in the downward movement posture The relationship may be L1 ≧ L2. If it is this relationship, a cap can be accommodated in a cap holding | maintenance part.

  Further, the latter aspect (2) of the restricting means is specifically provided with a cap holding part fitted to the cap in a downwardly moving posture of the pump head, and at least a part of the cap holding part is disposed on the pump head. In the upward movement posture, the pump head may be interposed between the top surface of the cap or a part of the pump mechanism, and may be brought into contact with the lower end of the pump head and the top surface of the cap or a part of the pump mechanism. . The cap holding part also functions as a stopper, and the pump head can be restricted from being pushed down. In order to interpose the cap holding portion between the pump head and the cap or a part of the pump mechanism in the upwardly moving posture of the pump head, specifically, the cap holding portion has the cap in the upwardly moving posture. It is only necessary to provide elasticity so that the diameter is smaller than that and the cap can be held in the downward movement posture. Alternatively, only the rear end portion of the cap holding portion may be bent or curved inward. In the downward movement posture of the pump head, the cap can be held by the cap holding portion, so that the protective cover can be attached even in the downward movement posture.

  It is preferable that the regulating means includes a head holding portion that is fitted to the pump head. The protective cover can be stably fixed to the pump container in the upwardly moving posture of the pump head. In addition, the pump head is held in the head holding portion in the upward movement posture of the pump head, and the pump head and cap are held in the head holding portion and the cap holding portion in the downward movement posture of the pump head, respectively. In the downward movement position, the protective cover is more stably attached to the pump container. Therefore, it is easy to remove the protective cover from the pump container in the upward movement position, and it is difficult to remove it in the downward movement position, which is suitable for conveyance. In this case, more preferably, the fitting force of the cap holding part is set higher than the fitting force of the head holding part. If it does in this way, it can fix to a cap strongly with a cap holding part, and it will be hard to remove a protection cover at the time of conveyance used as a downward movement posture.

  The cap holding part and the cap may be fitted, for example, by elastically holding the cap by the cap holding part, or by providing a protrusion on one of the cap holding part and the cap and on the other side. It is good also as a holding | maintenance by providing the recessed part which can be fitted with the protrusion.

  In addition, the fitting between the head holding part and the pump head, for example, may be such that the pump head is elastically held by the head holding part, or a protrusion is provided on one of the head holding part and the pump head. Further, a concave portion that can be fitted to the protruding portion may be provided on the other side so as to be able to be held.

  Further, as an aspect of the protective cover different from the above, the pump mechanism that can discharge the contents of the container body from the nozzle of the pump head by the vertical movement of the pump head and can maintain the pump head in the downward movement position is the container. In the protective cover of the pump container attached to the container main body via a cap screwed into the mouth of the main body, the protective cover is formed with a back opening into which the pump head and the cap of the pump container can be inserted, and the pump An upper wall that covers the top surface of the head, a head holding portion that is suspended from the edge of the upper wall and elastically holds the side surface of the pump head, and extends from the lower end of the head holding portion, and elastically holds the side surface of the cap And a cap opening that holds the back surface, the back opening is formed from the head holding part to the cap holding part, and the opening in the head holding part is the part where the top of the pump head fits The opening degree is made larger than the diameter of the upper part of the pump head, and when the pump head is moved upward, the lower end of the cap holding part comes into contact with the top surface of the cap or a part of the pump mechanism, thereby pushing down the pump head. The head holding portion and the cap holding portion may be a protective cover that is fitted to the pump head and the cap, respectively, in the regulated downward posture of the pump head. The opening in the head holding part is easy to insert the pump head because the opening degree of the portion where the upper part of the pump head is fitted is larger than the diameter of the upper part of the pump head.

  If a restriction wall bent inward from the lower end of the cap holding part is provided and the pump head is lowered, the restriction wall is locked to the lower edge of the cap. The state of wearing the protective cover is stable.

  The head holding part and the cap holding part are formed in an arc shape in plan view, and the arc part is preferably formed with a central angle larger than 180 degrees, and more preferably set at 210 to 240 degrees. If the central angle of the arc portion is larger than 180 degrees, the head holding portion and the cap holding portion cover most of the side surfaces of the pump head and the cap, so that the protective cover can be stably fixed to the pump container. On the other hand, if the central angle of the arc portion is smaller than 180 degrees, the protective cover tends not to be stably fixed in the upward movement posture and the downward movement posture. Moreover, if it is larger than 210 degree | times, the mounting state of a protective cover will become more stable. If it is larger than 240 degrees, it is not preferable because it becomes difficult to attach and detach the pump head and cap. The head holding portion and the cap holding portion have shapes corresponding to the outer peripheral shapes of the pump head and the cap, respectively.

  The material of the protective cover is not particularly limited, but is preferably made of a synthetic resin having flexibility. Examples thereof include, but are not limited to, polyethylene, polypropylene, silicone, urethane, and the like. If a synthetic resin having flexibility is used, the protective cover can be easily attached and detached.

  Moreover, it is preferable to provide the nozzle cap which coat | covers the nozzle which protrudes from the pump head of a pump container. Since the nozzle outlet is covered with the nozzle cap, it is possible to prevent the liquid adhering to the nozzle outlet from dripping. This nozzle cap may be formed integrally with a restricting means for restricting the pump head from being pushed down.

  According to the present invention, the protective cover can be attached to the pump container in both the upward moving position and the downward moving position of the pump head. In the upward movement posture, the restricting means restricts the pump head from being pushed down, so that an erroneous operation of the pump head can be prevented. Further, since the protective cover can be attached to the pump container in the downward movement posture, the pump head can be in the downward movement posture during conveyance. Therefore, it does not need to be bulky during transportation.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 4 is an enlarged front view of the main part in FIG. 2B, FIG. 5 is a cross-sectional view along AA in FIG. 3, FIG. 6 is a cross-sectional view along BB in FIG. FIG. 8 is a perspective view of the protective cover as viewed from the lower back, FIG. 9 is a plan view of the protective cover, FIG. 10 is a front view of the protective cover, and FIG. 11 is the protective cover. FIG. 12 is a cross-sectional view taken along the line CC in FIG.

  As shown in FIGS. 1 and 2, the pump container 1 of the present embodiment includes a container body 2 that is filled with contents such as a liquid, and a cap 3 that is screwed into the mouth 2 a of the container body 2. The pump mechanism 4 is mounted on the main body 2 and a protective cover 6 that covers the pump head 5 of the pump mechanism 4. As will be described later, the protective cover 6 can be mounted even in the downward movement posture of the pump head 5 while preventing an erroneous operation of moving the pump head 5 down erroneously in the upward movement posture of the pump head 5.

  The container body 2 is formed in a bottomed cylindrical shape, and has a cylindrical mouth portion 2a that opens at the top. A thread that can be screwed into the cap 3 is formed on the outer peripheral surface of the mouth 2a. An anti-slip groove 7 is formed on the outer peripheral surface of the cap 3.

  The pump mechanism 4 is provided so as to be axially rotatable with respect to the cap 3. The cap 3 is formed in a cylindrical shape having a top plate 3b having an insertion hole 3a formed in the center. A screw groove that can be screwed into the mouth 2a of the container body 2 is formed on the inner peripheral surface of the cap 3, and the pump mechanism 4 is detachably attached to the container body by screwing the cap 3 into the mouth 2a. It is done.

  Here, the pump mechanism 4 refers to the entire mechanism that starts with the pump head 5 and enables the contents of the container body 2 to be discharged by the vertical movement of the pump head 5. Specifically, the pump mechanism 4 is inserted into the insertion hole 3a of the cap 3, and has a cylindrical cylinder 8 with a suction pipe (not shown) suspended at the lower end thereof, and a sliding contact between the inner surface of the cylinder 8 and a spring (see FIG. (Not shown) a piston member (not shown) urged upward, a stem 9 standing at the upper end of the piston member and allowing the inside and outside of the cylinder 8 to enter and exit up and down through the insertion hole 3a; The pump head 5 is provided at the upper end of the cylinder 8 and has a thread groove formed on the inner peripheral surface thereof. The screw joint 10 is provided at the upper end of the cylinder 8 and engages with the screw groove on the inner peripheral surface of the pump head 5. And a stopper 11 that holds the top plate 3b so as to be rotatable with respect to the screwing portion 10. The pump head 5 is formed in a cylindrical shape having a top surface, and a nozzle 12 projects from the side surface, and the tip of the nozzle 12 serves as a discharge port 12a. The cylinder 8, the stem 9, the nozzle 12, and the discharge port 12a communicate with the suction port of the suction pipe.

  In the configuration of the pump mechanism 4 as described above, when the pump head 5 is pushed down, the piston is moved downward, and when the pump head 5 is stopped being pushed down, the piston and the pump head 5 are biased by the upward biasing force of the spring. Is returned to the upper limit position. By these operations, the piston moves up and down. By the vertical movement of the piston, the contents in the container body 2 sucked up from the suction port at the lower end of the suction pipe can be discharged from the discharge port 12a of the nozzle 12. That is, when the piston is moved upward by the biasing force of the spring, the liquid in the container body 2 flows into the cylinder 8 from the suction port through the suction pipe. When the piston is moved downward, the liquid in the cylinder 8 is discharged from the discharge port 12a through the stem 9 by pressure.

  The screwing portion 10 includes a disk-shaped base 10a having substantially the same diameter as the pump head 5, and a screw portion 10b having a smaller diameter and having a screw thread that is screwed to the pump head 5 on the side surface. The insertion hole 13c is formed in the center of the base 10a and the screw part 10b, and the stem 9 moves up and down through the insertion hole 13c. By screwing the pump head 5 into the screw portion 10b, the pump head 5 can be maintained in the downward movement posture. When the pump head 5 is maintained in the downward movement posture, the contents are not discharged and are not bulky, which is convenient at the time of transportation such as shipping.

  The stopper 11 is formed in a ring shape having a smaller diameter than the cap 3, and after the cap 3 is inserted into the cylinder 8, the stopper 11 is fixed to the side surface of the cylinder 8 in the cap 3 to hold the cap 3 rotatably. ing. With such a configuration, the pump mechanism 4 and the cap 3 are rotatably provided with respect to each other. Since only the cap 3 can be rotated when the pump mechanism 4 is attached to the container body 2, it is easy to attach and detach. In addition, if a packing is arranged on the lower surface of the stopper 11, liquid leakage from the container main body opening can be prevented. A packing may be interposed between the top plate 3b of the cap 3 and the top plate 3b.

  The protective cover 6 is made of a synthetic resin such as polypropylene, polyethylene, urethane, or silicone, but is not limited thereto. As shown in FIGS. 7 to 12, the protective cover 6 has a rear opening 13 into which the pump head 5 and the cap 3 can be inserted, and an upper wall 14 that covers almost the entire top surface of the pump head 5, A head holding portion 15 that hangs down from the edge of the wall 14 and covers and elastically holds the side surface of the pump head 5, and a cap holding portion that extends from the lower end of the head holding portion 15 and elastically covers the side surface of the cap 3 and holds it elastically. 16, a restriction wall 17 that is bent inwardly in a flange shape from the lower end of the cap holding portion 16, and whose lower surface is in contact with the top surface of the base 10 a of the screwing portion 10, and the nozzle 12 that protrudes from the front surface of the head holding portion 15. The nozzle cap 18 is formed so as to substantially conform to the outer peripheral shape of the nozzle cap 18. The rear opening 13 is formed continuously from the head holding part 15 to the cap holding part 16. Further, a notch 19 is formed between the upper wall 14 and the head holding portion 15 and between the head holding portion 15 and the cap holding portion 16 in the horizontal direction from the rear end portion. The upper wall 14, the head holding part 15, the cap holding part 16, and the restriction wall 17 are restriction means for restricting the pump head 5 from being pushed down.

  The protective cover 6 is formed so that the lower surface of the restriction wall 17 and the top surface of the pedestal 10a of the screwing portion 10 come into contact with each other in the upwardly moving posture of the pump head 5. With this configuration, the pump head 5 can be restricted from being pressed down. In addition to the above relationship, the protective cover 6 is formed so that the restriction wall 17 can be locked to the lower end edge of the cap 3 in the downward movement posture of the pump head 5. If it is this relationship, the cap 3 can be accommodated in the cap holding | maintenance part 16 in the downward movement attitude | position of the pump head 5. FIG. That is, the protective cover 6 can be mounted even in the downward movement posture of the pump head 5.

  Thus, the protective cover 6 holds the pump head 5 with the head holding portion 15 in the upward movement posture of the pump head 5, and the pump head with the head holding portion 15 and the cap holding portion 16 in the downward movement posture of the pump head 5. 5 and the cap 3 are held. Since the head holding portion 15 and the cap holding portion 16 are held in the lower movement posture, the lower movement posture has a higher fixing strength of the protective cover 6 to the pump container than the upper movement posture. Therefore, the protective cover 6 can be easily detached from the pump container in the upward movement posture, and the protective cover 6 is difficult to be removed during conveyance in the downward movement posture.

  The head holding portion 15 and the cap holding portion 16 are formed in an arc shape in plan view, cover about 3/4 of the side surface with the side surface on the discharge port 12a side as the center, and the remaining about 1/4 (the side opposite to the discharge port 12a). Are opened to form a back opening 13. The back opening 13 can be detachably attached to the pump head 5 and the cap 3. The head holding part 15 and the cap holding part 16 are formed along the outer peripheral surfaces of the pump head 5 and the cap 3, respectively, in the downward movement posture of the pump head 5. Thus, since the head holding part 15 and the cap holding part 16 cover about 3/4 along the side surfaces of the pump head 5 and the cap 3, the head holding part 15 and the cap holding part 16 are connected to the pump head 5 and the cap 3. Is generated, that is, an elastic holding force is generated. Therefore, the protective cover 6 can be fixed to the pump head 5 and the cap 3. Further, the elastic holding force of the cap holding part 16 is set higher than the elastic holding force of the head holding part 15. The cap holder 16 can be firmly fixed to the cap 3, and the protective cover 6 is unlikely to come off during transportation in the downward movement posture.

  The protective cover 6 has a strength that can prevent the pump head 5 from being pushed down by the upper wall 14 and the regulating wall 17 when a pressing force is applied to the upper wall 14, and from the rear opening 13. The pump head 5 and the cap 3 are flexible enough to be attached and detached. Furthermore, the notch 19 formed between the upper wall 14 and the head holding part 15 and between the head holding part 15 and the cap holding part 16 allows the head holding part 15 and the cap holding part 16 to be horizontally oriented. Therefore, the pump head 5 and the cap can be easily attached to and detached from the rear opening 13.

  The restriction wall 17 is preferably provided over the entire end portion of the cap holding portion 16 in terms of strength, but may be provided in a part.

  The nozzle cap 18 can receive liquid dripping from the nozzle outlet 12 a of the pump head 5. Further, two ribs 18 a are provided on the inner surface of the lower portion of the nozzle cap 18 in the depth direction. When the nozzle 12 is inserted into the nozzle cap 18, the two ribs 18a serve as a guide, so that the protective cover 6 can be easily attached to the pump head 5. The nozzle cap 18 may be inclined so that the bottom surface is lowered toward the nozzle tip side, or a recess may be formed on the bottom surface. The liquid dripping from the nozzle 12 becomes difficult to spill.

  According to the above configuration, the protective cover 6 can be attached to the pump container 1 in both the upward movement position and the downward movement position, and the same protective cover 6 can be used in combination. Since the restricting means restricts the pump head 5 from being pushed down in the upwardly moving posture, the pump head 5 can be prevented from being erroneously operated, and the protective cover 6 can be attached to the pump container 1 even in the downwardly moving posture. The pump head 5 can be transported in a downward movement posture. Therefore, it has the advantage that it is not bulky at the time of conveyance.

[Second Embodiment]
FIGS. 13 and 14 are views showing the second embodiment, FIG. 13 is an enlarged perspective view of a main part showing the upward movement posture of the pump container of the second embodiment, and FIG. 14 is also in the upward movement position of the pump container. It is a figure which shows the positional relationship of the cap holding | maintenance part 16 and the base 10a. In the present embodiment, the cap holding portion 16 can be interposed between the pump head 5 and the cap 3 in the upwardly moving posture of the pump head 5 without providing the upper wall 14 and the regulating wall 17 as the regulating means. The other structure is the same as that of the first embodiment. In the present embodiment, the restricting means is the cap holding portion 16. In addition, it is good also as a form which provided the upper wall 14 or the control wall 17 similarly to 1st Embodiment.

  The cap holding part 16 has a diameter smaller than that of the cap 3 in the upward movement posture of the pump head 5 and has elasticity so that the cap 3 can be held in the downward movement posture of the pump head 5. The length of the cap holding portion 16 in the vertical direction is substantially the same as the length between the top surface of the base 10a of the screwing portion 10 and the lower end of the pump head 5 in the upward movement posture of the pump head 5. . With this configuration, in the upwardly moving posture of the pump head 5, at least the rear end of the cap holding portion 16 is interposed between the top surface of the base 10a of the screwing portion 10 and the lower end of the pump head 5, and the upper end is the pump head. 5, the lower end comes into contact with the top surface of the base 10a of the screwing portion 10. Therefore, the rear end portion of the cap holding portion 16 functions as a stopper, and it is possible to restrict the pump head 5 from being pushed down.

  Further, in the downward movement posture, the cap holding portion 16 can hold the cap 3 by elasticity. Accordingly, the protective cover 6 can be mounted even in the downward movement posture.

[Third Embodiment]
FIGS. 15 to 21 are views showing a third embodiment. FIG. 15 is an enlarged perspective view of a main part showing a downward movement posture of the pump container of the third embodiment. FIG. 16 is a plan view of the same. 18 is a rear view, FIG. 19 is a DD sectional view in FIG. 17, FIG. 20 is an EE sectional view in FIG. 18, and FIG. 21 is an FF sectional view. In the first embodiment, the notches 19 are formed between the upper wall 14 and the head holding portion 15 and between the head holding portion 15 and the cap holding portion 16, but in this embodiment, FIGS. 19, the notch 19 is not provided, and the back opening 13 in the head holding portion 15 is characterized in that the opening degree of the portion into which the upper portion of the pump head 5 is fitted is larger than the diameter of the upper portion of the pump head 5. Therefore, other configurations are the same as those of the first embodiment.

  Thus, since the opening degree of the back opening 13 in the head holding portion 15 is larger than the diameter of the upper part of the pump head 5, the back opening 13 is formed from the front side of the nozzle 12. When mounted on the pump container 1 by using, the head holding part 15 and the cap holding part 16 are once expanded by the flexibility of the material, and then the side surface of the pump head 5 and the side surface of the cap 3 are expanded. Can be elastically engaged. The protective cover 6 can be attached to the pump container 1 with a simple configuration in which the notch 19 is not provided.
