Description

  The present invention relates to a volatile substance release container, such as a deodorant container or a fragrance container.

  In general, for an air freshener container, an impregnation rod extending from the container body to the upper part of the mouth and neck is inserted into the mouth and neck of the container body, and an overcap with a volatile window is fitted to the upper part of the container body. In addition, a plate-like impregnation member is brought into contact with the upper end of the impregnation rod so that the liquid that has entered from the impregnation rod through the impregnation member is volatilized.

  However, before using as a container, it is necessary to prevent the liquid from volatilizing. Therefore, a saucer extending from the mouth and neck to the inner peripheral surface of the overcap is provided, and a slit is formed in the overcap at the same height as the upper surface of the saucer, and is picked from one end of the seal that is airtightly attached to the upper surface of the saucer. It is known that a piece protrudes outward through a slit, an impregnation member is placed on the seal, and the seal is removed to come into contact with the impregnation rod (Patent Document 1).

JP2007-276831A

  However, in the container of Patent Document 1, it is necessary to attach a seal to the saucer and set the knob on one end side so as to pass through the slit, which is not easy to assemble.

  Moreover, in the said container, when the impregnation member inclines and falls in a saucer, for example by the bounce when a seal | sticker is peeled, the lower surface of an impregnation member and the upper end of an impregnation rod may not contact appropriately.

  The first object of the present invention is to provide a lid that blocks the impregnating rod and the impregnating member, and has a support piece that prevents the impregnating member from falling off during the operation of removing the lid, and can be easily manufactured. It is to propose a volatile substance release container.

  The second object of the present invention is to provide a volatile substance discharge container of the type in which the impregnation member descends and comes into contact with the impregnation rod so as to ensure the contact between the impregnation member and the impregnation rod.

The first means is
The impregnation rod 20 protruding from the inside of the trunk portion to the upper portion of the mouth neck portion is inserted into the mouth neck portion 6 standing from the trunk portion 4 of the container body 2 and the lid body 22 covering the upper portion of the impregnation rod is fitted to the mouth neck portion. Combined
A plurality of mounting plates 40 are suspended from the peripheral portion of the top wall of the overcap 24 with the volatile window 30 fitted to the body 4 side, and the impregnated member is inserted into the space V between these mounting plates. 46 is placed on the lid body 22,
Furthermore, a volatile substance discharge container provided with a support piece 42 for preventing the impregnation member 46 from falling off when the overcap 24 is removed from the container body at the bottom of the mounting plate,
The support piece 42 is provided so as to support the impregnating member by pressing the side surface 48 of the impregnating member 46.

  In this means, the impregnation member 46 is attached to the attachment plate 40 suspended from the top wall of the overcap 24 (see FIG. 3), and when the overcap is removed and the lid is removed, the support piece 42 of the attachment plate attaches the impregnation member. I support it. The support piece 42 is formed so as to be in pressure contact with the side surface 48 of the impregnating member. Although it is necessary to lower the impregnation member to a position where it comes into contact with the impregnation rod after removing the overcap 24 and removing the lid, a downward biasing means may be employed as will be described later. The impregnated member may be pulled down with a finger.

  The “impregnated member” may have a shape corresponding to the cross-sectional shape of the overcap in order to increase the surface area as much as possible. The “mounting plate” is a means for guiding the raising and lowering of the impregnating member, and is provided vertically so that the gap between them is constant. The “support piece” is means for retaining the impregnating member when the overcap is removed from the container body.

  The second means includes the first means, and the support piece 42 is molded in advance so as to protrude downward and inward from the lower portion of the mounting plate 40, and the impregnation member is inserted into the space. It is formed so as to bend upward and inward.

  This means proposes a support piece that protrudes inward and downward from the lower end of the mounting plate as described above. A sufficient pressure contact force can be obtained by bending the support piece upward and inward (see FIG. 3).

The third means includes the second means, and forms a biasing means 32 for pushing the impregnation member 46 downward in the central portion of the top wall of the overcap 24.
The pressing force of the urging means 32 is set larger than the supporting force due to the pressing of the supporting piece against the side surface of the impregnation member 46.

  In this means, an urging means 32 which is a position adjusting means for the impregnating member is provided. In the initial state, a lid that separates the impregnation member and the impregnation rod is provided. Therefore, except for the case where the lid is thin like a film piece, the lid is removed and the use of the container is started. Sometimes it is necessary to move the impregnation member toward the impregnation rod depending on the thickness of the lid. The urging means can be an elastic member (such as a spring) that expands and contracts due to an elastic force, and the pressing force decreases as it expands.

  According to the first aspect of the invention, since the support piece 42 provided on the mounting plate suspended from the back surface of the overcap 24 is pressed against the side surface of the impregnation member, the impregnation member 46 can be easily assembled.

  According to the invention relating to the second means, the support piece 42 is molded in advance so as to protrude downward and inward from the lower part of the mounting plate 40, and the impregnation member is inserted into the space to be inward and upward. Since it is formed to be bent, it is possible to sufficiently secure the holding force of the impregnating member.

  According to the third aspect of the invention, since the pressing force of the urging means 32 is greater than the support force due to the pressure contact of the support piece to the side surface of the impregnation member 46, the impregnation member 46 is pushed against the impregnation rod 20. It can be moved to the hit position, and the abutting can be ensured.

It is the longitudinal cross-sectional view which expanded the upper half part of the container of FIG. 1 is a side view of the main part of the container. It is explanatory drawing of the formation process of the principal part of FIG. It is explanatory drawing of the process of assembling an impregnation member in the principal part of FIG. It is a longitudinal cross-sectional view of the state which removed the overcap of the container of FIG. Furthermore, it is a front view which shows the state which removed the cover body and refitted the overcap.

  1 to 8 show a volatile substance release container according to a first embodiment of the present invention. The volatile substance discharge container includes a container body 2, a holder 8, an impregnation rod 20, a lid body 22, an overcap 24, and an impregnation member 46. The container body 2, the holder 8, the lid body 22, and the overcap 24 can be formed of a synthetic resin.

  The container body 2 has a mouth-and-neck part 6 erected from a straight cylindrical (cylindrical in the illustrated example) body part 4 via a shoulder part. The upper portion 4a of the body portion is formed in a small outer diameter fitting portion.

  The holder 8 has a fixed cylinder 10 fitted to the inner surface of the mouth-and-neck portion 6, and a hanging cylinder 14 is suspended from an inwardly flanged top plate 12 attached to the upper end of the stationary cylinder. The upper part of the drooping cylinder is formed into a short large diameter cylinder, the middle part is formed into a tapered cylinder with a small diameter at the lower end, and the lower part of the drooping cylinder is formed into a small diameter cylinder. A through hole 16 is formed in the tapered cylinder.

  The impregnation rod 20 is fitted in the lower part (small diameter cylinder) of the drooping cylinder 14. The lower end portion of the impregnating rod 20 extends to the bottom of the container body, and the upper end portion of the impregnating rod 20 extends slightly above the upper end of the mouth / neck portion 6.

  The lid body 22 is a closing tool that covers the upper end portion of the impregnation rod 20, and is a cap screwed to the outer surface of the mouth neck portion 6 of the container body in this embodiment. However, the structure of the lid can be changed as appropriate, and for example, a film piece adhered to the upper surface of the mouth and neck as in the seal of Patent Document 1.

  The overcap 24 is a crested elliptical cylinder, and the lower end portion of the cylindrical wall 26 is fitted to the upper portion 4a of the trunk portion. The overcap of this embodiment shall be molded with a synthetic resin agent having a little elasticity. The reason will be described later. A plurality of volatile windows 30 are opened in the cylindrical wall 26 and the top wall 28. Some of the volatile windows are located on the cylindrical wall portion outside the mounting plate including a support piece to be described later and the top wall portion above the mounting plate, and also serve as a die-cutting hole and a jig insertion hole to be described later.

  Further, an urging means 32 is formed at the central portion of the top wall 28 of the overcap 24. The biasing means is preferably a spring type that expands and contracts by elasticity as described above. This is because the pressing force is reduced by the extension, and the impregnating member stops at a point where it balances the frictional force with the support piece.

  In the example shown in the figure, a spiral cut is formed in the portion of the top wall as shown in FIG. However, the structure can be changed as appropriate.

  From the outer peripheral part of the top wall 28 of the overcap 24, a plurality of band-plate-shaped mounting plates 40 with one surface facing the center are suspended along a virtual circle surrounding the figure center of the top wall.

  The mounting plate 40 is formed with a support piece 42 for press-contacting a side surface of an impregnating member described later. In the illustrated example, the support piece 42 includes a first claw portion 44a that abuts on the impregnation member in the above-described pressure contact state, and a second claw portion 44b that abuts on the impregnation member inward and downward.

  The first claw portion 44a mainly prevents the impregnation member from slipping off, and the second claw portion 44b mainly prevents the impregnation member from unexpectedly rising due to an impact such as dropping the container onto the floor, and leaving the impregnation rod. To prevent. However, this configuration can be changed as appropriate. For example, the second claw portion 44b can be omitted.

  When the overcap 24 is formed, the support piece 42 extends downward in advance with an extension portion 41 having the first claw portion 44a and the second claw portion 44b on the outer surface side as shown in FIG. It may be formed by bending upward and inward according to the procedure described below. Thereby, the overcap including the locking piece and the mounting plate portion can be integrally formed. Compared with the case where the mounting plate with the support piece having the shape shown in FIG. 3 is formed from the time of forming, it is possible to avoid the complicated shape of the mold.

  The impregnating member 46 is a plate-like (disc-like in the illustrated example) member having a certain thickness, and is placed on the lid 22 and accommodated in a space V between the mounting plates. This impregnated member can be formed of a nonwoven fabric.

  5 and 6, the process of forming the support piece 42 is described. That is, as shown in FIG. 5, a jig T having a heating portion at the tip is inserted through the volatile window 30 from the outside of the extension 41 extending from the mounting plate 40 through the volatile window 30. . The extension part 41 is pushed in with this jig and heated to form a support piece 42 inclined downward and inward. However, pressing and heating as post-processing is a suitable example, and molding may be performed by other methods.

  Next, as shown in FIG. 6, when the impregnation member 46 is inserted into the space between the mounting plates, the first claw portion 44a of the support piece is pushed up on the upper surface of the impregnation member, and the entire support piece 42 is inverted upward and inward. To do. In this state, the first claw portion 44a and the second claw portion 44b are in pressure contact with the side surface 48 of the impregnation member.

  In a preferred example, four support pieces 42 are pressed against the side surface 48 of the impregnation member 46 from the front, rear, left and right, and the impregnation member is held by frictional resistance caused by the press contact. However, the number and arrangement of the support pieces can be changed as appropriate.

  In the lid mounting state shown in FIG. 1, the pressing force by the urging means 32 that is a coil spring is larger than the total frictional resistance between all the support pieces 42 and the impregnation member 46. However, after the overcap is removed from the container body, the pressing force decreases as the coil spring, which is the biasing means, extends. The strength of the spring of the urging means and the pressing force of the support piece so that the push-up force by the urging means and the frictional force between the impregnation member and the support piece are balanced before the support piece is removed from the side surface of the impregnation member 46. And the thickness of the impregnated member shall be selected.

  According to the above configuration, the coil spring that is the biasing means 32 in the state of FIG. 3 is compressed, and the impregnation member 46 is sandwiched between the biasing means and the lid body 22.

  When the container of the present application is used, the container body 2 is removed from the cover cap 24 as shown in FIG. Since the pressing force of the urging means exceeds the frictional force between the impregnation member and the support piece, the impregnation member 46 descends along the mounting plate 40. By lowering, the compression state of the urging means is relaxed, and the impregnation member stops when the pressing force and the pressing force of the support piece are balanced.

  Next, the lid body is removed, and the overcap is re-fitted to the container body. Since the impregnating member has moved downward from the initial state of FIG. 3 and the impregnating rod 20 protrudes upward from the mouth-and-neck portion, the upper end of the impregnating rod 20 abuts the lower surface of the impregnating member 46. The liquid in the container enters the impregnating member through the impregnating rod, volatilizes, and is released into the air.
