Abstract

PROBLEM TO BE SOLVED: To provide a content discharging amount switching mechanism for a small amount spraying and a large amount spraying, which is easy to use, and has a small number of parts.SOLUTION: On an operation section 7, a main operation section 7a for operation mode setting, and a subsidiary operation section 7b for the selection of a small amount/large amount spraying of a content are provided in a manner to be simultaneously operable by one hand. A needle rear end section 12a moving in a content passage region 8c is made to be able to abut on the front surface receiving section 7c of the subsidiary operation section. When the main operation section 7a and the subsidiary operation section 7b are depressed, the needle 12 is urged forward by the subsidiary operation section, and the front end surface 12d abuts on a nozzle bottom surface 11g, and the content is jetted by the small amount from a discharging hole 11a through a groove section 11b. When the major operation section 7a alone is depressed, the needle 12 moves backward (shown as the right direction in the figure) by the pressure of the content, and the front end surface 12d is separated from the nozzle bottom surface 11g, and the content is jetted by the large amount through a space region between the nozzle bottom surface and the needle front end surface which is formed by the separation.

Description

  The present invention relates to a content discharge amount switching mechanism capable of changing a content discharge amount from a discharge hole of a passage setting portion to a content of a container body to an external space region, and an aerosol type product and a pump type product provided with this mechanism.

  In particular, in addition to the operation unit for setting the operation mode, a sub-operation unit for adjusting the amount of content flowing into the discharge hole (= the amount of content flowing into the external space) is set simultaneously, including the operation unit. The present invention relates to a content discharge amount switching mechanism provided in an operable form.

  In the mechanism for switching the content outflow amount from the content discharge hole to the external space region, it is desirable that the operation is simpler and the number of components is smaller, and the present invention meets such a demand. .

  The application target of the content discharge amount switching mechanism of the present invention is aerosol type and pump type products.

  In the present specification, the content discharge hole side is referred to as “front”, and on the opposite side, for example, the illustrated operation unit side is referred to as “rear”. That is, the left direction in FIGS. 1 (a), 2 (a), 3 (a) and 4 is “front”, and the right direction is “rear”.

  The present applicant attaches a substantially sheath-like discharge hole member to the front end side opening portion of the passage setting portion set to the operation button for setting the operation mode in a rotatable manner, and allows the rotation operation to the discharge hole member. Based on this, a direct discharge operation mode with a large content discharge amount and a spray operation mode with a small content discharge amount have been proposed (see Patent Document 1).

  In this content discharge amount switching mechanism, a slide member that is biased toward the content discharge hole by the elastic force of the coil spring is disposed in the passage setting portion inside the operation button. In addition, a groove for forming a content vortex is formed on the bottom surface of the discharge hole member.

  In a state where the slide member moves forward as much as possible by the elastic action of the coil spring and comes into contact with the bottom surface portion of the discharge hole member, a small amount of the content flowing into the bottom surface portion passes through the groove and sprays to the discharge hole portion. It becomes a state and flows out.

  Then, the slide member is retracted against the coil spring based on the turning operation with respect to the discharge hole member and is held in that position, that is, in a state where the slide member is separated from the bottom surface portion of the discharge hole member, The contents flowing into the part mainly flow out in a large amount of direct injection into the discharge hole through this space (not the contents spiraling groove).

JP 2006-122760 A

  The above-described content discharge amount switching mechanism (switching mechanism between small quantity injection and large quantity injection) has an advantage that each operation mode of small quantity spray / large quantity direct injection can be selected only by rotating the discharge hole member. is doing.

However, in the case of this content release amount switching mechanism,
(11) The user cannot operate both the discharge hole member for selecting the operation mode of the small amount spray / the large amount of direct injection and the operation unit for setting the original operation mode with one hand.
(12) The number of parts of the content discharge amount switching mechanism (switching mechanism for small amount discharge of contents, large amount discharge) by using an elastic member (coil spring) to set and hold the slide member in the forward direction in a small amount spray state There are many,
This leaves room for improvement.

  Therefore, in the present invention, the main operation part for setting the operation mode and the sub operation part for switching the small amount discharge (small amount injection) and the large amount discharge (large amount injection) can be simultaneously set by one user's hand. It is provided in a possible form, and it is intended to make it convenient for the user operation of the content discharge amount switching mechanism.

  In addition, instead of using the above-mentioned elastic member (coil spring) as a drive source for setting and holding the slide member in a small discharge state, the operation force of the user with respect to this sub-operation part is used, thereby The purpose is to reduce the number of parts of the discharge amount switching mechanism.

  Moreover, while using the 1st operation member which can be rotated with respect to the cover action part for the operation part protection attached to the container main body as a main operation part, it can be rotated with respect to the main operation part as a sub-operation part. An object of the present invention is to simplify the simultaneous setting operation of the main operation unit and the sub operation unit.

  In addition, when setting the content small amount discharge state, it is only necessary to operate the sub-operation unit, that is, when the user operates the sub-operation unit, the main operation unit is also driven by a part of the sub-operation unit to set the operation mode. An object is to shift to an operation state, thereby further simplifying the simultaneous setting operation of the main operation unit and the sub operation unit.

  In addition, a non-passage closed space region (not a content passage region) that accompanies the movement of the slide member is disposed on the cylindrical portion that is disposed in the internal space region so that the slide member is movable and forms the content passage region. A hole for allowing the air to enter and exit from the external space and for allowing the convex receiving portion (a part of the slide member) corresponding to the sub operation portion to move toward the sub operation portion. The purpose of this is to ensure the selective setting operation of a small amount release state or a large amount release state of the contents.

  Further, a single member in which the entire main operation portion, sub-operation portion, cover action portion, and cylindrical portion are integrally formed is used, thereby simplifying the assembly work of the content discharge amount switching mechanism and the mechanism. The purpose is to further reduce the number of parts.

Respectively.

  Here, the stem 3, the cover body 4 (the lower cylindrical portion 5 + the arc wall-like standing portion 6 + the operation portion 7, 7 ′ + the injection cylindrical portion 8), the nozzle 11 and the needle 12 are made of, for example, polypropylene, polyethylene, polyacetal, Made of plastic, such as nylon or polybutylene terephthalate. The container body 1 is made of metal, for example.

  As described above, the cover body 4 including the lower cylindrical portion 5, the pair of arcuate wall-like standing portions 6, the operation portions 7 and 7 ', the injection cylindrical portion 8, and the like is an integrally molded product.

The main feature of the illustrated content discharge amount switching mechanism is that, depending on the content of the single operation of the user with respect to the main operation unit 7a and the sub operation units 7b and 7b ′,
(21) A small amount sprayed state in which the front end surface 12d of the needle 12 is in contact with the nozzle bottom surface 11g by a pressing operation on the main operation unit 7a and the sub operation units 7b and 7b ′;
(22) A large amount of direct injection state in which the front end surface 12d of the needle 12 is separated from the nozzle bottom surface 11g by a pressing operation only on the main operation portion 7a;
Is selectively set.

  In any of the pressing operations (21) and (22), the main operation portion 7a rotates in the clockwise direction in the drawing with the thin portion 5b of the lower cylindrical portion 5 as the center. As the main operation portion rotates, the stem 3 is pushed in an oblique direction.

  When the stem 3 is pushed down, the well-known valve mechanism on the stem side shifts from the closed state until then to the open state, and the contents of the container main body 1 pass through the stem 3 and the vertical hole portion 8a, and the cylindrical portion for injection 8 flows into the content passage area 8c.

  This inflowing content is further injected from the discharge hole 11a to the external space region through the content passage region 11e of the nozzle 11.

  Here, the pressure in the content passage area 8c increases due to the inflow of the content, and the needle 12 is separated from the discharge hole 11a of the nozzle 11 by receiving the pressure on the front side surface of the reverse skirt portion 12b rearward. Try to move backwards.

For the driving force of the needle 12 to the rear,
(31) In the case of the above (21) in which the main operation portion 7a and the sub operation portions 7b and 7b ′ are substantially pressed, the sub operation portion is illustrated with the thin portion 8d of the cylindrical portion 8 for injection as the center. Since the needle 12 is forcibly rotated in the clockwise direction, the protruding portion 12a is urged forward by the front outer surface receiving portions 7c and 7c ′ of the sub operation portion, and the front end surface 12d of the needle 12 is the bottom surface of the nozzle. It is positively held in a state of contact with 11g, that is, a small amount of sprayed state (see FIG. 2),
(32) In the case of the above (22) in which only the main operation portion 7a is pressed and the sub-operation portions 7b and 7b ′ are not pressed, the above-mentioned (31) with respect to the needle 12 from the sub-operation portion Since the forward urging action does not occur, the needle 12 moves backward based on the increase in the pressure in the content passage area 8c, and the front end face 12d is separated from the nozzle bottom face 11g, that is, a large amount of direct injection. Transition to the state (see FIG. 3).

  The small spray state shown in FIG. 2 is generated when the contents from the contents passage area 11e pass through the plurality of grooves 11b of the nozzle 11 and then merge into the output space area 11c to form a vortex. This is because the width of the groove 11b is narrower toward the side closer to the discharge hole 11a and the flow becomes faster.

  3 is generated because the content from the content passage area 11e is mainly sufficiently wider than the groove 11b of the nozzle 11 (between the nozzle bottom surface 11g and the needle front end surface 12d). This is because it flows into the discharge hole 11a from the separated space region.

  In the case of the operation unit 7 ′ shown in FIG. 4, when the sub operation unit 7b ′ is pressed and rotated obliquely downward, a pair of pieces 7d ′ formed at both ends in the width direction of the sub operation unit are the main operation units. The upper surface portion of 7a 'is driven downward.

  That is, the main operation portion 7a ′ is also moved to the operation mode operation position by the pressing operation of only the sub operation portion 7b ′. Of course, when only the main operation portion 7a ′ is pressed, the sub operation portion 7b ′ does not follow this.

  Since the main operation part driving piece 7d 'is formed on both ends in the width direction of the sub operation part 7b', the longitudinal length of the operation target upper surface of the main operation part 7a 'has the piece 7d'. This is substantially the same as that of the main operation unit 7a not performed.

In addition, of course, this invention is not limited to the content of illustration, for example,
(41) As the operation unit, various operation members such as a vertical movement type, a tilt operation type and a trigger lever type are used.
(42) A groove for atomizing the contents is formed not on the bottom surface of the nozzle but on the front end surface of the needle.
(43) The groove portion for atomizing the contents is omitted, and instead of a small amount spray state, a small amount direct injection state in which the separation distance between the nozzle bottom surface and the needle front end surface is shorter than the large amount direct injection state (for example, on the nozzle bottom surface) The state where the front end surface of the needle is in contact with the rear end portion of the provided longitudinally standing piece portion) is set.
You may do it.
