Description

  The present invention relates to a shoulder cover structure that is securely attached to the mounting cup side of an aerosol-type product and exhibits a decorative effect, and can be easily removed from the container body side and reused when the container body is discarded after the contents are exhausted. .

  In particular, the present invention relates to a shoulder cover structure including a lower shoulder cover that is fitted to a mounting cup and is not removed, and an upper shoulder cover that is to be reused and is detachable from the lower shoulder cover.

  In this specification, the side of the attaching / detaching operation unit is referred to as “front”, and the side opposite to the 180 degrees around the stem is referred to as “rear”. For example, the left side of FIGS. 1, 3, 5, 6 and 8 is “front” and the right side is “rear”.

  Conventionally, as a reusable shoulder cover structure, when the shoulder cover is screwed and integrated with the inner cover consisting of the bulging part weakly fitted in advance to the undercut of the mountain cup, the bulging part is the direction of the undercut. The thing of the aspect which is made to deform | transform into a strong fitting state is proposed (refer patent document 1).

  When reusing the shoulder cover and the inner cover, the shoulder cover is first removed from the inner cover together with the nozzle to change the strong fitting state between the bulging portion and the undercut to the weak fitting state. Then, remove the inner cover from the mountain cup, and replace and discard only the container.

JP 2014-108814 A

  Thus, the conventional reusable shoulder cover structure is composed of a two-piece configuration of a screwed shoulder cover and an inner cover that is hidden behind the shoulder cover and is not exposed.

  In order to separate the two-piece shoulder cover, first, the shoulder cover and the inner cover are moved by relative rotation between the container body and the shoulder cover while paying attention to the rotation of the shoulder cover and the inner cover. After the screwed state is released and the inner cover is set in a loosely fitted state with the mounting cup, the inner cover is removed from the container body side.

  For this reason, there has been a problem that the operation for removing the shoulder cover and the inner cover is complicated and not intuitive for the user.

  In addition, since the user performs the work of fitting the inner cover to the mountain cup, it is difficult to make a strong fitting setting corresponding to variations such as mountain cup deformation that is likely to occur due to the caulking process when attaching the mountain cup to the container. There was a point.

  Therefore, in the present invention, the shoulder cover attached to the mountain cup is composed of a lower shoulder cover and an upper shoulder cover, both of which are externally exposed surfaces exhibiting a decorative action, and the lower shoulder cover is fixed to the mounting cup, The cover is set to be detachable from the lower shoulder cover

  In other words, the user simply discards the work such as removing the lower shoulder cover fixed to the mounting cup, and for example, only performs the work of attaching and detaching the upper shoulder cover to the lower shoulder cover while being fixed at the product shipping stage. is there.

  Remove the upper shoulder cover from the lower shoulder cover that is integral with the mounting cup and reattach it to a new lower shoulder cover (container body), for example, when disposing of the aerosol-type product after exhausting the contents of the container body. It is what you use.

  Here, the injection button 4, the lower shoulder covers 5, 15, 25, 35, the upper shoulder covers 6, 16, 26, 36 and the lock member 7 are made of plastic made of, for example, polypropylene, polyethylene, polyacetal, nylon, polybutylene terephthalate or the like. belongs to.

  The container body 1 and the stem 3 are made of, for example, plastic or metal. The mounting cup 2 is, for example, metallic.

  FIG. 1 and FIG. 2A show a shoulder cover structure in which the upper shoulder cover 6 is attached to the lower shoulder cover 5 using a lock member 7 separate from the upper shoulder cover 6.

  The attachment state of the lower shoulder cover 5 and the upper shoulder cover 6 includes the locking action of the locking hole 5d and the locking projection 6d, the lower locking projection 5f, and the upper locking projection 6e. Is held by the clamping action of the lock member 7.

  When the used container body 1 is discarded, as shown in FIG. 2 (b), the lock member 7 is rotated 90 degrees to the left or right, and then the lower lock projection 5f and the upper lock projection 6e. Pull out and remove, lift the front side of the upper shoulder cover 6 to release the contact state between the intermediate cylindrical portion 6b and the front arcuate upright portion 5e, and move the upper shoulder cover 6 forward to engage the locking hole The locking projection 6 d is pulled out from 5 d and the upper shoulder cover 6 is removed from the lower shoulder cover 5. At this time, the spray button 4 held on the upper shoulder cover 6 is also removed from the stem 3 and the container body 1 and the lower shoulder cover 5 are discarded.

  The injection button 4, the upper shoulder cover 6 and the lock member 7 are attached to the container body 1 having the new lower shoulder cover 5 in the reverse order of removal and reused.

  3 and 4 show a shoulder cover structure in which the upper shoulder cover 16 is attached to the lower shoulder cover 15 using a locking member 16e integrated therewith.

  The attachment state of the lower shoulder cover 15 and the upper shoulder cover 16 includes the locking action of the locking hole 15d and the locking projection 16d, and the locking of the locking projection 15f and the locking hole 16g. Is retained by the action.

  Since the downward convex portion of the lower surface of the tip of the locking convex portion 15f is in contact with the inner edge of the locking hole portion 16g, the locking member 16e does not rotate carelessly.

  When the container body 1 that has been used is discarded, the locking member 16e is pivoted strongly in the direction of the arrow in FIG. 3, the locking convex portion 15f is pulled out from the locking hole portion 16g, and the front side of the upper shoulder cover 16 is lifted to the middle. The contact state between the cylindrical portion 16b and the front arcuate standing portion 15e is released, the upper shoulder cover 16 is moved forward, the locking convex portion 16d is pulled out from the locking hole portion 15d, and the upper shoulder cover 16 is removed from the lower shoulder cover 15. At this time, the spray button 4 held by the upper shoulder cover 16 is also removed from the stem 3 and the container body 1 and the lower shoulder cover 15 are discarded.

  The injection button 4 and the upper shoulder cover 16 are attached to the container body 1 having a new lower shoulder cover 15 in the reverse order of removal and reused.

  FIG. 5 shows a shoulder cover structure in which the upper shoulder cover 26 attached to the lower shoulder cover 25 in a strongly fitted state is removed from the lower shoulder cover 25 by the coin 8.

  The attachment state of the lower shoulder cover 25 and the upper shoulder cover 26 is maintained by a strong fitting action between the inner annular convex portion of the intermediate cylindrical portion 26b and the outer annular convex portion of the upper cylindrical portion 25c.

  When discarding the container body 1 that has been used, the coin 8 is inserted into the opening 26d and rotated so as to be lifted or twisted, so that the inner annular convex portion and the upper cylindrical shape of the intermediate tubular portion 26b in the strongly fitted state are disposed. The upper shoulder cover 26 is removed from the lower shoulder cover 25 by forcibly separating the outer annular convex portion of the portion 25 c. At this time, the spray button 4 held on the upper shoulder cover 26 is also removed from the stem 3 and the container body 1 and the lower shoulder cover 25 are discarded.

  The injection button 4 and the upper shoulder cover 26 are attached to the container body 1 having the new lower shoulder cover 25 in the reverse order of removal and reused.

  6 to 8 show a shoulder cover structure in which the upper shoulder cover 36 is attached to the lower shoulder cover 35 by its vertical movement operation and rotation operation.

  The attachment state of the lower shoulder cover 35 and the upper shoulder cover 36 is held by the locking action between the terminal end portion of the crank-shaped guide hole 35d and the guide convex portion 36c.

Since the guide convex portion 36c of the upper shoulder cover 36 is held by the moderation convex portion 35e at the end of the crank-shaped guide hole portion 35d, the upper shoulder cover 36 does not rotate carelessly.
Even if a strong force is applied and the upper shoulder cover 36 rotates, the upper shoulder cover 36 is moved when the guide convex portion 36c passes through the crank portion (second vertical groove) of the crank-shaped guide hole portion 35d. Since it is necessary to push the button downward, it will not come off accidentally.

  When discarding the container body 1 that has been used, the upper shoulder cover 36 is strongly rotated clockwise in plan view, and then the guide projection 36c is connected to the crank-shaped guide hole 35d and the inner side as shown by the arrow in FIG. The upper shoulder cover 36 is removed from the lower shoulder cover 35 by rotating and vertically moving the upper shoulder cover 36 in the order of the clockwise direction in the plan view, the downward direction, the clockwise direction in the plan view, and the upward direction so as to follow the guide groove 35c. At this time, the injection button 4 held by the upper shoulder cover 36 is also removed from the stem 3 and the container body 1 and the lower shoulder cover 35 are discarded.

  The injection button 4 and the upper shoulder cover 36 are reused by being attached to the container body 1 having a new lower shoulder cover 35 in the reverse order of removal.
