Description

  The present invention relates to an aerosol container.

  Various types of aerosol containers include a container body with a stem protruding from the upper end and an ejection head fitted to the stem, and the liquid in the container body is ejected from the ejection head of the ejection head when the ejection head is pushed down. It has been proposed (see, for example, Patent Document 1).

  In conventional aerosol containers, when the container body is tilted, the container liquid is ejected, the container body is laid sideways, the container liquid is ejected, or the container body is inverted, and only the gas is ejected. Is often ejected, resulting in a problem that the remaining amount of the stored liquid eventually increases.

JP 2007-145411 A

  The present invention has been made in view of the above points, and has a structure in which liquid cannot be ejected when the container body is tilted. As a result, the above-described useless gas injection can be prevented, and the remaining amount of stored liquid can be reduced. We propose an aerosol container suitable for use in a stationary upright state that can efficiently eject the contained liquid as much as possible.

  The first means is configured as follows. That is, the stem 16 protrudes from the upper end of the stem 16 so as to be able to be pushed down in an upward biased state, and the container body A from which the stored liquid is ejected from the upper end of the stem 16 by the depression of the stem 16 and the shoulder cover B fitted to the container body A And the ejection head D fitted to the stem 16, and the shoulder cover B is gradually lowered from the highest level position H located outside the stem 16 and is located at the other level outside the stem 16. And a ball C that moves along the passage p when the container body A is tilted. The ejection head D is attached to the stem 16 by fitting the lower end portion of the vertical cylinder 33 to the stem 16. 33, an opening 35 that communicates with the inside of 33 is opened, and when the container body A is tilted, the ball C moves from the lowest level position L to the highest level position H, and the ball C at the highest level position H moves. , Jet head D To prevent depressed to prevent the depression of the stem 16.

  The second means is configured as follows. That is, in the first means, the passage p is provided with the highest level position H at the front of the stem 16 and the lowest level position L at the rear of the stem 16, and gradually descends on both sides of the stem 16 from the highest level position H. Thus, a concave groove shape having a circular shape in plan view reaching the lowest level position L is formed.

  The third means was configured as follows. That is, in the first means, the passage p has a highest level position H in front of the stem 16 and a pair of lowest levels L1 and L2 on both sides behind the stem 16. It has a level position L, and has a concave groove shape in an arc shape in plan view that gradually descends on both sides of the stem 16 from the highest level position H to reach the lowest level position L. The first lowest level position L1 and the second lowest level position L2 A locking projection 28 with which the lower surface of the rear portion of the ejection head D abuts is provided.

  The fourth means is configured as follows. That is, in the second means or the third means, the shoulder cover B is mounted by fitting the fitting cylinder portion 21 suspended from the back surface of the annular top plate portion 20 to the outer periphery of the upper end portion of the container body A. Then, the guide tube portion 24 suspended from the inner peripheral edge of the top plate portion 20 is used as the outer peripheral wall 25, and the inner peripheral wall 27 is erected from the inner peripheral edge of the bottom wall 26 extending inward from the lower end edge of the guide tube portion 24. The passage p is integrally defined in the outer peripheral wall 25, the bottom wall 26, and the inner peripheral wall 27.

  The aerosol container of the present invention includes a passage p in which the shoulder cover B gradually descends from the highest level position H located outside the stem 16 to reach the lowest level position L located outside the stem 16. The ball C moves along the path p when the container body A is tilted. When the container body A is tilted, the ball C moves from the lowest level position L to the highest level position H. The ball C that is pressed prevents the ejection head D from being pushed down and prevents the stem 16 from being pushed down. For example, since the lower surface of the ejecting head D pushed down to the ball C at the highest level position H comes into contact with the stem 16 to prevent the stem 16 from being pushed down, the liquid can be prevented from being ejected when the container body A is tilted. It is possible to prevent unnecessary gas injection and to reduce the remaining amount of the storage liquid as much as possible and to efficiently eject the storage liquid. For such reasons, it is suitable as a container intended for use in a stationary upright state.

  The passage p has a highest level position H in front of the stem 16 and a lowest level position L in the rear of the stem 16, and has a circular shape in plan view from the highest level position H gradually descending on both sides of the stem 16 to reach the lowest level position L. In the case of forming a concave groove shape, since a two-passage configuration that passes through both sides of the stem 16 from the lowest level position L to the highest level position H is adopted, the container body A can be quickly accommodated in all directions. Further, the ball C is moved from the lowest level position L to the highest level position H, and the stem 16 can be prevented from being pushed down more reliably when the container body A is tilted.

  The passage p has a highest level position H in front of the stem 16 and a pair of lowest level positions L of a first lowest level position L1 and a second lowest level position L2 on both sides behind the stem 16, from the highest level position H. The bottom surface of the rear portion of the ejection head D is formed between the first lowest level position L1 and the second lowest level position L2. In the case where the abutting locking projection 28 is provided, the ejection head D is prevented from tilting in the lateral direction, and only the ejection head D is tilted slightly forward, and the ejection head D is prevented from tilting forward. Since the stem 16 is pushed down at this time, when the ball C is at the highest level position H, the lower surface of the ejection head D is surely brought into contact with the ball C to reliably prevent the stem 16 from being pushed down.

  The shoulder cover B is attached by fitting a fitting cylinder portion 21 suspended from the back surface of the annular top plate portion 20 to the outer periphery of the upper end portion of the container body A, and is guided from the inner peripheral edge of the top plate portion 20. Are used together as the outer peripheral wall 25, and the inner peripheral wall 27 is erected from the inner peripheral edge of the bottom wall 26 extending inwardly from the lower end edge of the guide tube portion 24, and the above-described inner wall 27, bottom wall 26, inner peripheral wall 27 When the passage p is integrally defined, there is an advantage that the passage p can be formed with an efficient and efficient arrangement and can be easily assembled to the container body A.

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

  1 to 4 show a first embodiment of an aerosol container, in which 1 denotes an aerosol container. The aerosol container 1 includes a container body A, a shoulder cover B, a ball C, and an ejection head D. For convenience of explanation, in FIG. 1, the left side is the front part, the right side is the rear part, the near side is the right side part, and the back side is the left side part. The same applies to FIG. 5 of the second embodiment.

  The aerosol container 1 is configured such that the liquid in the container body A, for example, a cosmetic liquid is ejected from the ejection port 35 of the ejection head D in the form of liquid, mist, or foam.

  As the container body A, a known aerosol container body is used. The stem is stood up from the upper end so that the stem can be pushed in an upward biased state, and the built-in discharge valve is opened by pushing the stem against the upward biasing force. The storage liquid is provided with a known mechanism for ejecting from the upper end of the stem 16.

  The container body A in the illustrated example has a lid plate 13 that closes the upper end opening of the mouth-and-neck portion 12 erected from the upper end of the cylindrical body portion 10 via the shoulder portion 11, and the peripheral portion of the lid plate 13. Is wound and fixed around the mouth-and-neck portion 12 to form an annular protrusion 14. Further, the stem 16 is erected upward through the support cylinder 15 erected integrally with the central portion of the lid plate 13. The stem 16 is mounted so as to be able to be pushed in an upwardly biased state. Although not shown in the figure, a push-down valve-opening discharge valve that opens when the stem 16 is pushed into the container body A and closes when the stem 16 is raised. Built in.

  The shoulder cover B includes an annular top plate portion 20 in which an outer peripheral edge portion is depressed and an inner portion other than the depressed portion is inclined and raised inward, and a fitting cylinder that is suspended from the depressed inner peripheral portion of the top plate portion 20. The portion 21 is fitted to the outer periphery of the annular protrusion 14 of the container body A and attached to the container body A. An annular recess is formed at the inner peripheral lower end of the fitting cylinder portion 21, and a plurality of circumferential engagement ribs 22 project at equal intervals in the annular recess, and project at the lower end of the engagement rib 22. The mating ridge is engaged with a downward step formed on the lower outer periphery of the annular projection 14 to prevent upward slipping. Further, the peripheral wall portion 23 is suspended from the outer peripheral edge of the top plate portion 20, and the lower end of the peripheral wall portion 23 is suspended on the outer peripheral edge of the shoulder portion 11 of the container body A. Further, a guide tube portion 24 is suspended from the inner peripheral edge of the top plate portion 20.

  Further, the shoulder cover B includes a passage p that gradually descends rearward from the highest level position H at the front part on the outside of the stem 16. In the illustrated example, the passage p is defined by a circular groove in plan view provided around the stem 16, and the bottom wall of the stem 16 has a center position at the front of the stem 16 as a highest level position H, and a center portion at the rear of the stem 16. The position is the lowest level position L, and a two-pass form is adopted in which the position gradually descends from the highest level position H to both sides and reaches the lowest level position L. Specifically, an outer peripheral wall 25 used in combination with the guide tube portion 24, and a circular bottom wall 26 that has a predetermined width extending inward from the lower end edge of the outer peripheral wall 25 and gradually descends backward from the front portion. The inner peripheral wall 27 is erected from the inner peripheral edge of the bottom wall 26.

  The ball C moves in the passage p due to the inclination of the container body A. Therefore, when the container body A is placed at a normal flat surface position or is held in a horizontal state, the ball C is positioned at the lowest level position L of the passage, and the container body A Is moved forward to the highest level position H of the passage p.

  The ejection head D includes a casing 32 having a top wall 31 extending from an upper end edge of the peripheral wall 30, and a lower end portion of a vertical cylinder 33 projecting from the casing 32 is fitted to the upper end of the stem 16 to be attached to the container body A. Wearing. In the casing 32, a nozzle 34 communicating with the inside of the vertical cylinder 33 and the base end portion projects through the peripheral wall 30 and protrudes forward, and an outlet 35 is opened at the tip.

  The case where the aerosol container 1 comprised as mentioned above is used is demonstrated. When the ejection head D is pushed down with the container body A horizontally or placed on the horizontal placement surface, the ball C is brought to the lowest level position L of the passage p as shown in FIG. Therefore, the ejection head D can be lowered, and the stem 16 is pushed down accordingly. As shown in FIG. 2, the discharge valve in the container body A is opened and the pressurized liquid is discharged from the ejection port 35 via the stem 16. Erupted. When the pressure of the ejection head D is released, the stem 16 is raised by the upward biasing force, the discharge valve is closed, and the ejection head D is raised and returns to the original state.

  Further, when the container body A is held in an inclined state or held in an inverted state, for example, as shown in FIGS. 3 and 4B, the ball C moves to the highest level position H. In the case where it is stuck, the lower surface of the ejection head D comes into contact with the ball C and the ejection head D cannot be pushed down. In the present invention, when the ball C moves to the highest level position H, the lower surface of the ejection head D is not necessarily in contact with the ball C. There may be a slight gap between them, and in short, it is only necessary that the presence of the ball C prevents the stem 16 from being pushed down for injection. This is the same in the following embodiments.

  FIGS. 5 to 8 show a second embodiment of the aerosol container. In this embodiment, the configuration of the shoulder cover B is different from the first embodiment, and the rest is substantially the same as the first embodiment. Only the different parts will be described, and the same parts will be denoted by the same reference numerals and the description thereof will be omitted.

  The container body A is the same as that of the first embodiment.

  As in the first embodiment, the shoulder cover B includes an annular top plate portion 20 in which the outer peripheral edge portion is depressed and the inner portion other than the depressed portion is inclined and raised inward, and the inner peripheral edge of the depressed portion of the top plate portion 20 The fitting cylinder part 21 suspended from the part is fitted to the outer periphery of the annular protrusion 14 of the container body A and attached to the container body A. An annular recess is formed at the inner peripheral lower end of the fitting cylinder portion 21, and a plurality of circumferential engagement ribs 22 project at equal intervals in the annular recess, and project at the lower end of the engagement rib 22. The mating ridge is engaged with a downward step formed on the lower outer periphery of the annular projection 14 to prevent upward slipping. Further, the peripheral wall portion 23 is suspended from the outer peripheral edge of the top plate portion 20, and the lower end of the peripheral wall portion 23 is suspended on the outer peripheral edge of the shoulder portion 11 of the container body A. Further, a guide tube portion 24 is suspended from the inner peripheral edge of the top plate portion 20.

  Similarly to the case of the first embodiment, the shoulder cover B is provided with a passage p that gradually descends backward from the highest level position H of the front part on the outside of the stem 16. The passage p in the present example is defined by a concave groove having a circular arc shape in plan view provided around the stem 16, and the bottom wall has the center portion front position of the stem 16 as the highest level position H, and both sides on the rear side of the stem 16. The position is set to the first lowest level position L1 and the second lowest level position L2, and the two-passage form is adopted in which the position gradually descends from the highest level position H to both sides and reaches the first lowest level position L1 or the second lowest level position L2. Yes. In other words, the central portion of the concave groove having a circular arc shape in plan view is located in front of the nozzle 34, and each end portion of the concave groove having a circular arc shape in plan view is located on both sides behind the nozzle 34.

  Specifically, the outer peripheral wall 25 used in combination with the guide tube portion 24, the bottom wall 26 that gradually descends rearward from the front portion with a predetermined width extending inward from the lower end edge of the outer peripheral wall 25, and the bottom wall 26 The inner peripheral wall 27 upstanding from the inner peripheral edge of the guide tube portion 24 and the side surfaces 28a of the locking projections 28 formed by recessing the center of the rear portion of the guide tube portion 24 into a predetermined width inward in an inverted L-shaped cross section. It is made.

  The ball C moves in the passage p due to the inclination of the container body A. Accordingly, when the container body A is placed at a normal flat surface position or is held in a horizontal state, the ball C is either the first lowest level position L1 or the second lowest level position of the passage. It is located at L2 and moves to the highest level position H of the passage p by tilting the container body A forward.

  The ejection head D has the same form as that of the first embodiment, but differs in that the rear lower surface of the peripheral wall 30 is substantially in contact with the upper surface 28b of the locking projection 28.

  The case where the aerosol container 1 comprised as mentioned above is used is demonstrated. When the ejection head D is pushed down with the container body A placed horizontally or placed on the horizontal placing surface, the ball C is, for example, the lowest level of the passage p as shown in FIG. 5 or FIG. Since it is in the first lowest level position L1, which is the position L, the ejection head D can be lowered. As shown in FIG. 6, the stem 16 is pushed down to open the discharge valve in the container body A, and the pressurized liquid is supplied. It is possible to eject from the ejection port 35 through the stem 16. In this case, when the ejection head D is pushed down, the rear surface of the lower surface of the peripheral wall 30 of the ejection head D is in contact with the upper surface 28b of the locking projection 28, and the stem 16 is pushed down with the ejection head D tilted forward. The stem 16 is configured so that it can be tilted slightly, and since the push-down width of the stem 16 is very small, there is no functional problem. When the pressure of the ejection head D is released, the stem 16 is raised by the upward biasing force, the discharge valve is closed, and the ejection head D is raised and returns to the original state.

  Further, when the container body A is held in an inclined state or held in an inverted state, the ball C has moved to the highest level position H as shown in FIGS. 7 and 8B, for example. In this case, the ball C comes into contact with the lower surface of the ejection head D to prevent the ejection head D from being pushed down, and the stem 16 cannot be pushed down. In this case, in this example, the upper surface of the locking projection 28 and the upper surface of the ball C are substantially on the same plane, and therefore, when the ejection head D is pressed, any position on the top wall 31 of the ejection head D is pressed. The ejection head D cannot be pushed down.
