Description

The present invention relates to a push-down head type ejection container.

For example, an aerosol container is widely used in which a top opening of a container body is closed with a mounting cup and a pressing head is attached to the upper end of a stem that stands up through the cup (Patent Document 1).
JP 07-309382 A JP 2006-124002 A

    In this type of container, a pattern or the like may be printed on the front surface of the body portion of the container body, or a packaging seal may be applied with the front surface as the center of design. In this case, in consideration of the appearance of the container, it is usual to provide the nozzle of the pressing head in the front thereof. However, there is a possibility that the ejection direction of the nozzle and the front direction of the package are shifted during use.

    Here, in the field of containers, as a means for preventing rotation of the other member with respect to one member, it is widely practiced to mesh the ribs attached to each member (Patent Literature). 2). However, in the existing container body, for example, the aerosol container listed in Patent Document 1, since there is a fixed structure, it is difficult to incorporate a meshing rib into the structure of the container body to prevent rotation. There are often.

    Accordingly, the main object of the present invention is to provide a pressing head type ejection container that can regulate the rotation of the pressing head with respect to the container body, and can easily separate and separate the container body and other parts. In particular, it is an object of the present invention to provide a push-down head type container including a rotation restricting means that can be applied as it is to an existing container structure such as an aerosol container.

The first means erects the stem 8 having the push-down head 10 with a nozzle at the upper end to stand upward from the center of the top portion 4 and extends to the outer peripheral portion of the top portion 4 in the circumferential direction and at least on the inner and outer sides. A container body 2 formed with an engagement strip 6 having
A cylindrical mounting member 14 that is attached to the container body 2 through the engagement strip 6 and has an upper portion of the inner peripheral surface serving as a guide surface 44 for guiding the push-down head 10;
Between the engagement strip of the container body 2 and the lower part of the cylindrical mounting member 14, a rotation restricting means 50 for limiting the rotation of the cylindrical mounting member is formed.
Further, a pressing head type ejection container provided with a detent means 30 for the pressing head 10 with respect to the cylindrical mounting member 14,
The cylindrical mounting member 14 is formed of a cylindrical base body 16 for mounting on the engagement strip 6 and a cylindrical operating body 40 that is rotatably fitted to the cylindrical base body 16. The rotation restricting means 50 is
A plurality of elastic leg pieces 28 projecting from the lower end of the cylindrical base body 16 to the side of the engaging strip 6,
The cylindrical operating body 40 has a cylindrical wall, and includes a pressing wall portion 48 formed so as to push each leg piece 28 toward the engaging strip 6 when the cylindrical operating body is fitted to the cylindrical base body 16. ,
The leg piece 28 is configured to be clamped between the pressing wall portion 48 and the engaging strip 6 by this pressing.

  In the pressing head type container body configured to prevent the pressing head with nozzle from rotating with respect to the cylindrical mounting member and to restrict the rotation of the cylindrical mounting member with respect to the container body, The mounting member is divided into a fixed part to the container body and a movable (rotating) part, and the leg piece protruding from the fixed part is tightened between the lower part of the movable part and the engagement strip of the container body, and the friction The rotation is restricted by force. By utilizing the frictional force, it can be easily applied to an existing container that does not have a special structure for meshing as described above.

  The “top portion” may include a shoulder portion between the top end portion and the trunk portion in addition to the horizontal top end portion.

  The “engagement strip” refers to an engagement means that has a side surface that extends long in one direction and can be used as a friction surface. It may be a step having an inward or outward step surface as a side surface, as well as an engaging protrusion having an inner surface and an outer surface, raised from the periphery. Moreover, although the engaging strip may be formed over the entire circumference of the outer peripheral portion of the top portion, it may be preferably disposed intermittently at some appropriate positions in the circumferential direction.

  The “tubular mounting member” has a function of restricting the rotation of the pressing head so that the pressing head can be raised and lowered with respect to the top of the container body. The term “cylindrical” as used herein is not limited to a single cylinder, and has a hollow shape at the center and a long shape in the cylinder axis direction, which can transmit a rotation regulating force. Shall point to.

    The “rotation restricting means” has a function of preventing the pressing head from rotating with a force that is applied when the pressing head is manually operated in a normal use state. Therefore, if a force exceeding that level is applied, the pressing head rotates, but even if the pressing head is slightly deviated from the original circumferential position, a rotation restricting force almost equal to that before rotation can be expected. This is different from the fact that when one of the pair of meshing ribs unexpectedly gets over the other, the rotation stopping force is almost lost. Therefore, even when an unexpected force is applied in the present invention (for example, even when a child tries to forcibly turn around), the pressing head does not deviate extremely from the correct circumferential position. Moreover, the engaging part is not damaged.

    The “cylindrical base” is a fixing portion attached to the container body side of the cylindrical mounting member, and has leg pieces as means for fixing to the engaging strip. When the engaging strip is an engaging projection having both inner and outer side surfaces, the leg piece may be provided so as to engage with either the inner side surface or the outer side surface (FIGS. 1 and 5). Further, if necessary, the structure of the leg piece and the pressing wall portion shown in FIG. 1 can be incorporated in the embodiment shown in FIG.

    The “leg piece” protrudes downward like a kind of anchor from the cylindrical base body, and is formed so as to be sandwiched between the engaging strip and the pressing wall portion. Although it is not necessary to be in a form that meshes with the engagement strip like a normal anchor, the frictional force with this engagement side surface is formed as a shape corresponding to the engagement side surface of the engagement strip as shown in the illustrated example below. It is desirable to make it large. The leg pieces in the illustrated example to be described later are easy to swing in and out, for example, by making the base end portion (the connecting portion with the cylindrical base) thin, but omit the thin portion to increase the strength of the leg pieces. A plate portion that can be bent and deformed may be used. Each leg piece is elastic enough to expand laterally outward by pushing the pressing wall portion through the cylindrical base body and return to the original position by extracting the pressing wall portion upward.

    The “cylindrical operating body” is a movable part of the cylindrical mounting member, and a part thereof is exposed to the outside so that the user can touch it. Although this cylindrical operating body is screwed into the cylindrical base in the preferred illustrated example described later, it may be simply fitted (fitted).

The second means includes the first means, and the cylindrical operating body 40 is screwed onto the cylindrical base body 16 and the cylindrical operating body 40 is screwed off from the cylindrical base body 16. The fastening of the leg piece 28 between the pressing wall 48 and the engaging strip 6 can be eliminated.

  When the leg piece 28 is tightened between the pressing wall portion 48 and the engagement strip 6, if the tightening is excessively strong in order to make the rotation restricting force sufficient, the cylindrical operation body is rotated at the time of separation. May become difficult. Therefore, in this means, the cylindrical operating body can be forcibly detached from the cylindrical base using a screwing mechanism.

The third means includes the first means or the second means, and the leg piece 28 protrudes from the lower end portion of the inner peripheral surface of the cylindrical base body 16, beside the inner surface of the engagement strip 6. And extend to
The cylindrical wall lower part which the said cylindrical operation body 40 has inward rather than the engaging strip 6 is made into the press wall part 48,
The leg piece 28 can be held between the outer surface of the pressing wall portion 48 and the inner surface of the engaging strip 6.

  In this means, a part of the cylindrical operating body assembled so as to be operable from the outside is extended to the inside of the cylindrical base so that the leg pieces of the cylindrical base are pressed outward from the inside. is there.

The fourth means includes the first means or the second means, and projects the leg piece 28 from the lower end portion of the outer peripheral surface of the cylindrical base body 16 to the side of the outer surface of the engagement strip 6. While extending
The cylindrical wall lower part which the said cylindrical operation body 40 has outside from the engaging strip 6 is made into the press wall part 48,
The leg piece 28 can be sandwiched between the inner surface of the pressing wall 48 and the outer surface of the engaging strip 6.

  In this means, the operation part and the pressing wall part, which are functions of the cylindrical operation body, are gathered outside the container, so that a simple and lean shape can be expected.

The fifth means includes any one of the first means to the fourth means, and the container body 2 is an aerosol container body,
The mounting cup and the top 4 of this aerosol container body,
Furthermore, the standing edge part which has in the outer peripheral part of the mounting cup is used as the engagement strip 6.

    In this means, the existing structure of the conventional aerosol container is used as the top part or the engaging strip of the present application.

The sixth means includes any one of the first means to the fourth means, and the anti-rotation means 30 is provided on one of the guide surface 44 of the cylindrical mounting member 14 and the outer peripheral surface of the pressing head. The vertical groove 46 is formed by a vertical groove 46 and the engaging protrusion 12 attached to the other and slidable in the vertical groove.

The invention according to the first means has the following effects.
A rotation restricting means 50 for restricting the rotation of the cylindrical mounting member 14 is formed between the engaging strip of the container body 2 and the lower portion of the cylindrical mounting member 14, and further the push down of the cylindrical mounting member 14 Since the detent means 30 for the head 10 is provided, it is possible to prevent the depressing head 10 from rotating while being used with respect to the container body.
○ Since the rotation restricting means 50 is configured to fasten the leg piece 28 between the pressing wall portion 48 and the engaging strip 6, the positional relationship in the circumferential direction of the cylindrical mounting member 14 with respect to the container body 2 It can be tightened irrespectively, and it is not necessary to consider the direction at the stage of mounting the cylindrical mounting member on the container body, so that the positioning operation is easy.
○ Turning is restricted by the frictional force of tightening, and when an unexpected turning force is applied, the turning restriction force is not lost even if the pressing head is slightly deviated from the correct position. As in the case of the meshing rib described above, the meshing portion is rarely damaged.

  According to the second aspect of the invention, the fastening of the leg piece 28 can be forcibly released by screwing the tubular operating body 40 from the tubular base body 16, so that even if the initial tightening state is tight. Separation work can be done easily.

  According to the invention relating to the third means, the leg piece 28 is clamped by being sandwiched between the inner side surface of the engagement strip 6 and the outer surface of the pressing wall portion 48 of the cylindrical operating body 40, and this pressing wall portion. Since the compressive stress only acts on the material, it does not loosen due to elongation and deformation, so there is little possibility that the tightening force will decrease due to secular change.

  According to the fourth aspect of the invention, since the leg piece 28 is sandwiched between the outer surface of the engaging strip 6 and the inner surface of the pressing wall portion 48, the pressing wall portion is placed outside the container, that is, by the user. Since it can be arranged at a position where it can be easily operated, the structure of the cylindrical operation body 40 is simplified, and as a result, the structure of the entire container can be simplified.

  According to the invention relating to the fifth means, since the existing structure of the conventional aerosol container is used as the top part or the engaging strip of the present application, the present invention can be applied to the existing aerosol container as it is, and it is economical. is there.

    According to the sixth aspect of the invention, the anti-rotation means 30 is attached to the longitudinal groove 46 vertically provided on one of the guide surface 44 of the cylindrical mounting member 14 and the outer peripheral surface of the pressing head, and the other. In addition, since the engaging projection 12 is slidable in the longitudinal groove, the pressing head can be reliably prevented from rotating.

  1 to 4 show a pressing head type container according to a first embodiment of the present invention.

  This container includes a container body 2, a cylindrical mounting member 14, and a cover 60.

  The container body 2 is an aerosol-type container body, and the top portion 4 of the container body is formed of a metal mounting cup. The outer edge portion of the mounting cup is curled around the upper end of the cylindrical wall of the container body, and the engagement strip 6 is formed by this curled portion. Further, a stem 8 that also serves as a liquid guide pipe is erected through the central portion of the top. A pressing head 10 having a lateral nozzle 11 is attached to the upper end of the stem. Further, locking projections 12 for preventing rotation are provided on both front and rear sides of the lower end of the outer surface of the pressing head.

  The cylindrical mounting member 14 is formed of a cylindrical base 16 and a cylindrical operating body 40.

  The cylindrical base 16 projects outwardly outward flange 20 from the lower part of the base cylinder 18, and a short engagement cylinder 22 and a long support cylinder 24 are formed in the inner and outer double cylinders from the outer peripheral portion of the back surface of the outward flange. Is drooping. The lower end of the support tube 24 is locked to the upper surface of the shoulder portion of the container body, and the inner surface of the lower end of the engagement tube 22 is fitted to the outer surface of the engagement strip 6. The base cylinder portion above the outward flange is formed in a threaded cylinder with the cylindrical operating body. A reinforcing wall 26 is provided between the base tube portion below the outward flange and the upper half of the engagement tube 22.

  Further, a plurality of leg pieces 28 protrude from the lower end of the base cylinder 18 slightly inward and downward toward the inner surface of the engagement strip 6. These leg pieces are arranged in such a manner that the lower end small-diameter taper cylinder hanging from the lower end of the base cylinder 18 is cut at equal intervals and divided as shown in FIG. 3 which is a bottom view of the cylindrical base. . And each leg piece is provided so that it may expand to the side outward by the pressing of the below-mentioned press wall part, and it may be pressed on the inner surface of the engaging strip 6. FIG. In the illustrated example, the outer side surface of each leg piece 28 is shaped so as to fit into the depression on the inner side surface of the engagement strip 6 (the shape of the “shaped” in the longitudinal section).

  The cylindrical operating body 40 has an operating cylinder 42 screwed onto the outer surface of the upper half of the base cylinder 18 of the cylindrical base body, and a collar 43 attached to the lower end of the operating cylinder is placed on the outward flange 20. In addition, the cylinder wall is suspended from the upper end of the operation cylinder 42 to the vicinity of the lower end portion of the engagement strip 6 along the inner surface of the operation cylinder 42 via the inward flange. The upper half of the cylinder wall is a guide cylinder of the push-down head, and a vertical groove 46 with an upper end opening is provided vertically on the guide surface 44 that is the inner surface of the cylinder part. The lower half of the cylindrical wall is formed on the pressing wall 48. Further, a partition plate is provided in the middle of the cylindrical wall, and the above-mentioned stem is erected through the partition plate.

  Here, the leg piece and the pressing wall portion 48 form a rotation restricting means 50. The vertical groove 46 and the locking projection 12 form a detent means 30 for the pressing head.

  The cover 60 is fitted to the outer surface of the operation cylinder 42.

  The cylindrical mounting member and the cover can each be formed of a synthetic resin material.

  In the above configuration, in the state of FIG. 1, the cylindrical mounting member 14 is difficult to rotate with respect to the container body 2 by tightening the leg piece 28 between the engagement strip 6 and the pressing wall portion 48. In addition, the push-down head 10 is not rotatable with respect to the cylindrical mounting member 14 by fitting the engagement protrusion 12 into the vertical groove 46. Therefore, in a normal use state, the position of the nozzle 11 of the pressing head 10 does not shift with respect to the container body.

  When separating and discarding the container, the support cylinder 24 of the cylindrical base body 16 is held with one hand while the cover is removed, and the operation cylinder 42 of the cylindrical operation body 40 is held with the other hand, and the cylindrical operation cylinder is held with respect to the cylindrical base body. When the screw is unscrewed, the pressing wall portion 48 is pulled out from the base tube 18 of the cylindrical base body 16 to be elastically restored inward, whereby the fastening of the leg piece 28 with the engaging strip is loosened. Thereby, the cylindrical base | substrate 16 can be easily removed from the top part of the container body 2. FIG.

  FIG. 4 shows a modification of the present embodiment, in which the operation surface of the cylindrical operation body 40 is enlarged by modifying the shapes of the cylindrical base body and the cylindrical operation body. That is, the cylindrical operation body 40 hangs down the second operation cylinder 42b from the lower end of the first operation cylinder 42a via the flange 43. Correspondingly, the position of the outward flange 20 is changed downward, and the support cylinder 24 is suspended from the lower end of the engagement cylinder 22 via the outward projecting portion.

  Hereinafter, other embodiments and examples of the present invention will be described. In these embodiments, the same components as those in the first embodiment are denoted by the same reference numerals and description thereof is omitted.

  5 and FIG. 6 show a modification of the structure of the cylindrical base body including the leg pieces and the cylindrical operation body. That is, the cylindrical base body 16 has a lower end portion of the base cylinder 18 placed on the engaging strip 6 and a guide cylinder substantially equal in length to the base cylinder is suspended from the upper end of the base cylinder via an inward flange. A vertical groove 46 is provided vertically on the guide surface 44 of the guide tube. A plurality of leg pieces 28 are suspended from the outer surface of the lower half portion of the base tube 18 via the outwardly projecting portion 52. These leg pieces are formed by intermittently drilling one thread (or screw groove) in a spiral shape from the bottom to the top in the circumferential direction. Therefore, if a cylindrical body having a thread groove having the same pitch as that of the thread is fitted, it is provided so as to be smoothly fitted to the outer surface of each leg piece. However, the leg pieces in FIG. 5 are not shaped as they were molded, but originally the shape of each leg piece is expanded downward and downward, as shown in FIG. 5 by fitting the pressing wall portion 48 to the outer surface. This is a vertical state.

    The outer peripheral portion of the upper end surface of the outward projecting portion 52 is depressed. An inward flange 54 attached to the upper end of the operation cylinder 42 of the cylindrical operation body 40 is engaged with the depressed portion. The operation cylinder also serves as the pressing wall 48. In the present embodiment, the cylindrical operation body 40 is configured as a substantially single simple structure.

  In this embodiment, when each leg piece of FIG. 5 originally removes the cover 60 and then unscrews the cylindrical operating body 40 from the cylindrical base body, the leg pieces are in an expanded state as shown in FIG. Returns to elasticity. As a result, the tightening of the leg pieces is eliminated, so that the cylindrical base body 16 can be easily detached from the container body 2.

  FIG. 7 is an example in which the second embodiment of the present invention is applied to a pump container. In this example, instead of the curled engaging strip of the aerosol container, a step formed on the shoulder of the pump container is used as the engaging strip, and the outer surface of the step is placed between the tubular operating body 40. The leg piece is clamped.
