Description

  The present invention relates to a content discharge mechanism in which a direct injection operation and a spray operation of a container content to an external space are performed in parallel in an operation mode, and an aerosol type product and a pump type product provided with this mechanism.

  Examples of the container contents include various properties such as liquid, foam (foam), paste, gel, and powder.

  Products to which the present invention is applied include hair restorers, hair styling agents, hair treatment agents, hair dyes, cosmetics, shaving foams, pharmaceuticals, quasi-drugs, cooling agents, muscle anti-inflammatory agents, and droplets ( Vitamins, etc.), paints, gardening agents, insecticides, cleaners, deodorants, urethane foam, fire extinguishers, lubricants, cleaning agents, cleaning agents, antiperspirants, repellents (insecticides), adhesives, laundry glue There are various uses such as.

  In addition, as the operation format, aerosol type and pump type products are targeted. In addition, the "pump type" used in this specification means that the volume of the contents storage space is reduced by the user pressing, for example, the operation unit or a part of the container (such as a peripheral surface). It shows a method in which the contents inside are discharged into the external space, and is a concept including a so-called extrusion type and tube type.

In the conventional discharge form of the container contents,
・ Spatial spray (the active ingredient is suspended in the air as atomized particles)
・ Surface spray (releases particles with larger diameter than air spray)
・ Powder ejection (releases solid particles)
・ Bubble squirt (released as foam)
・ Stream-like jetting (Jet or stick-like discharge)
・ Paste-like squirt (released as paste or gel)
・ Liquid release (released as droplets)
(See Patent Document 1).

In addition, there is also one in which different discharge forms can be selectively set by switching the operation of the content discharge mechanism (see Patent Document 2).

Respectively. The direct injection hole 21 ″ is longer than the direct injection holes 21 and 21 ′ shown in FIGS.

  The content discharge mechanism of the present invention is characterized in that a parallel injection hole 21 and a spray hole 22 are provided in a parallel operation output piece 20 and these are operated in parallel during the operation mode, whereby the container contents Objects can be discharged into the external space almost simultaneously in the direct injection state and in the spray state.

  As shown in FIG. 1, an output piece 20 for parallel operation in which a direct injection hole 21 and a spray hole 22 are formed is attached to a columnar portion 13 of the operation button 10.

Between the lateral passage 12 which is the output part of the operation button 10 and the external space,
・ Passage S-Direct injection route A
・ Passage S-fog spray route B
The two contents flow paths are formed.

  As shown in FIG. 2, the output piece 20 for parallel operation is entirely sheath-shaped, and an annular protrusion 23 a for fitting to the operation button 10 is provided on the outer peripheral surface thereof.

A shaped portion 24 is provided.

  Furthermore, a flow direction restricting portion 25 for making the flow of the contents spiral is provided inside. Between the flow direction restricting portions, turning groove portions 26 that are narrowed toward the center are individually formed, and the contents that have passed through the turning groove portions become mixed vortex flows in the central space region 27. .

  A spray hole 22 is formed in the central space 27. Therefore, the contents flow into the spray hole 22 in a vortex, and the flow velocity itself when entering the spray hole is increased by passing through the narrow portion of the turning groove 26. The contents discharged from the spray holes are mist-like.

  On the other hand, the direct injection hole portion 21 formed in the inlet side portion of the turning groove portion 26 of the output piece 20 exists on the extension line of the passage S (a part of) the content passage S as will be described later. The contents discharged from the hole are in a direct injection state.

  When the parallel operation output piece 20 is attached to the operation button 10, the opening side of the output piece may be inserted into the columnar portion 13 of the operation button. At this time, the output piece 20 is positioned and guided with each of the flat base portions 24 abutting against the side surface 13b of the cylindrical portion 13.

A passage S for contents is set between the side and the outer peripheral surface of the cylindrical portion.

  The circumferential range in which the passage S is set is not only the portion where the flat trapezoidal portion 24 is not formed inside the output piece 20 but also the portion where the cylindrical portion 13 does not contact in the flat trapezoidal portion 24. Is also included in this circumferential range. In addition, the contact relationship between the flat trapezoidal portion 24 and the cylindrical portion 13 is in a substantially line contact state. The passage S is a so-called upstream passage common to the direct injection route A and the spray route.

  In the operation mode in which the operation button 10 is pressed, the valve (not shown) is opened, and the contents of the container body (not shown) pass through the stem 30, the vertical passage 11 and the horizontal passage 12 and flow into the passage S.

The contents flowing into the passage S are
-Released by the direct injection route A passing through the direct injection hole 21;
-It is also emitted in the form of a mist by the spray route B passing through each swivel groove 26-central space 27-spray hole 22.

  In the case of the output piece 20 (2) for parallel operation in FIG. 4, the direct injection hole 21 'is formed on the outer end side (the body part 23 side) of the flow direction restricting part 25.

  In the case of the output piece 20 (3) for parallel operation in FIG. 5, in order to extend the length from the output portion of the lateral passage 12 of the operation button 10 to the spray hole 22 or the like, that is, the length of the passage S, The intermediate member 40 is fitted and held inside, and the trunk portion 23 'is lengthened by the amount corresponding to the intermediate member.

  In the case of the output piece 20 (3) for parallel operation shown in FIG. 6, an annular convex portion 40a ′ for shortening the distance from the inner peripheral surface of the body portion 23 ′ on the output portion side of the lateral passage 12 of the operation button 10 is provided. The provided intermediate member 40 'is held. The shape of the output piece itself of FIG. 6 is the same as that of FIG.

  Here, the cross-sectional area for passage of the contents of the passage S is narrowed by the annular convex portion 40a ′, and the flow rate there is increased to increase the direct injection performance of the contents. Moreover, since the said cyclic | annular convex part becomes the shape which bites into the internal peripheral surface of the output piece 20 (3), an intermediate member can be reliably attached to an operation button.

When attaching the output piece 20 (3) of FIGS. 5 and 6 to the columnar portion 13 of the operation button 10,
(a) Push the intermediate member 40, 40 'into the output piece until the narrow plane side comes into contact with the flow direction restricting portion 25 as shown in the figure,
(b) Next, the opening side of the output piece in which the intermediate members 40 and 40 ′ are incorporated may be inserted into the cylindrical portion 13 of the operation button 10. At this time, the output piece 20 (3) is positioned and guided while each of the flat trapezoidal portions abuts against the side surface 13b of the cylindrical portion 13.

  The parallel operation output piece 20 (3) shown in FIG. 7 includes a direct injection hole 21 ″ longer than the direct injection holes 21 and 21 ′ shown in FIGS. 1 to 6, and the output shown in FIG. The piece 20 has a shape provided with an annular upright portion 50 for narrowing the spraying range of the contents on the output side of the spray hole portion 22.
