Description

  The present invention relates to a fragrance container containing a fragrance such as a deodorant, a deodorant, and a fragrance, particularly a gel fragrance.

  The container of the gel-like fragrance mainly seals between the main body holding the gel-like fragrance and the gel-like fragrance held in the main body before use. In use, the cover part is lifted from the main body and a gap is formed between the main body and the fragrance component is gradually exposed to the external atmosphere by exposing the fragrance to the external atmosphere. It is designed to have deodorizing, deodorizing, aroma and other actions by volatilizing and releasing. The intensity of the desired scenting action can be changed by the user adjusting the lifting amount of the cover from the main body to adjust the size of the gap, thereby changing the area where the scenting agent is exposed to the external atmosphere. Set by

As a mechanism for adjusting the lifting amount of the cover part, a hollow pole is erected at the center of the main body part that holds the fragrance, and a columnar part that fits the pole is provided on the cover part. It was made by shifting relative to the axial direction. As a structure of the fitting portion, there are a friction fitting structure that slides in the axial direction and a screw coupling structure and a structure that lifts the cover by rotating and loosening the screw of the screw coupling portion.

  However, in the case of the structure according to the above-described prior art, the weight is adjusted by changing the weight of the fragrance, the temperature of the environment where the fragrance container is installed, the deformation of the material constituting the container over time, etc. There was a problem that the size of the gap would change. Such a problem is particularly noticeable in the case of a hanging type container in which the weight of the main body including the fragrance is directly applied to the joint with the cover. In the case of the adjustment method by coupling with screws, in order to suppress such a change in the gap amount with time, a method of reducing the screw angle (that is, making the screw pitch fine) can be considered. If the pitch is made fine, the screw must be turned many times when adjusting the cover lifting amount, which is very complicated for the user. On the other hand, when the angle of the screw is increased (the pitch of the screw is rough), there is a problem that the set gap amount changes because the frictional force of the screw portion cannot withstand the weight of the fragrance or the container.

  In view of the problems of the prior art, the present invention can quickly and easily adjust the amount of the exposed fragrance (ie, the sustained release amount of the fragrant), and the adjusted clearance changes over time. An object is to provide a fragrance container that does not.

In order to achieve the above object, in the present invention, the fragrance agent container is constituted by a main body portion that holds the fragrance agent, and a cover portion that is fitted to the main body portion and covers the fragrance agent, The body part or the cover part can be opened and closed by rotating, and either the body part or the cover part has a hollow pole and the other has a columnar part, and the hollow pole inner peripheral surface or outside the columnar part At least one spiral groove is provided on any one of the surfaces, and at least one protrusion A having an inclination angle equal to the inclination angle of the spiral groove is provided on the other, and the main body portion and the It is possible to adjust the degree of opening of the fragrance container by changing the vertical positional relationship by relative rotation with the cover portion, and the hollow pole inner peripheral surface or the columnar portion outer surface of the protrusion A Project radially against the bottom of the spiral groove Brought into contact with, elastically and the columnar portion and the hollow pole by being energized provided protrusions B adapted to locally press the bottom of the spiral groove to the radial direction direction, the The ridges B are provided at the same height with respect to the bottom surface of the main body, and when there are two ridges B, they are 180 degrees from each other. It was arranged to be located on the vertex.

  The inclination angle of the groove slope of the spiral groove depends on the size of the fragrance container and the fragrance, but is preferably relatively large so as to reach a full gap amount in one or two revolutions. Further, the number of spiral grooves depends on the size of the container and the fragrance, but is preferably 2 to 3. Furthermore, the elastic force of the protruding ridges protruding in the radial direction and elastically biased includes selection of the height of the protruding ridges, provision of axial notches in the columnar portions, selection of the elastic modulus of the material, etc. Therefore, it is preferable to set appropriately in consideration of the weight of the flavoring agent. Further, the protrusion may be formed such that one of the protrusions engages with the spiral groove and the other protrudes in the radial direction and elastically biases, or the protrusion protrudes in the radial direction and elastically protrudes. It is good also as a protrusion part to energize.

  The present invention is particularly useful for a suspension-type fragrance container, but is also effective as a mounting-type fragrance container. Moreover, it can be effectively applied not only to the fragrance container but also to a sustained-release drug container by the same method of use.

  By adopting the structure as described above, according to the fragrance container of the present invention, a desired fragrance gap amount can be set with a small number of rotations, and the set fragrance gap amount is set between the spiral groove and the spiral groove. Even if time elapses, the hollow pole and the columnar portion are securely held by frictional engagement with at least one protrusion engaging with the spiral groove and elastic biasing by the protrusion protruding in the radial direction. The set amount of fragrance clearance is less likely to change.

Hereinafter, the present invention will be described in detail according to preferred embodiments with reference to the drawings.
1 to 5 show a preferred embodiment of the present invention, which is a suspended fragrance container.

FIG. 1 is a perspective view showing a closed state before use of a hanging type fragrance container 1 according to the present embodiment, and FIG. 2 is a perspective view showing an opened state when the fragrance container 1 is used. is there.
FIG. 3 is a cross-sectional view of the fragrance container 1 in the state shown in FIG. As shown in FIG. 3, the fragrance container 1 is mainly composed of a main body portion and a cover portion. The main body portion is composed of the main body 2 and a hollow pole 3 erected at the center of the main body 2. A gel-like fragrance 4 indicated by an imaginary line is fitted and held around the pole 3.

  On the other hand, the cover part is composed of a cover 5 and a cap 6. The cover 5 and the cap 6 are integrated by being fitted at a portion indicated by symbol a in FIG. The fragrance container 1 is mainly used in a suspended state. Therefore, as shown in FIG. 4, a hook portion 7 for suspending the fragrance container 1 is attached to the top end of the cap 6. Is provided. A columnar portion 8 extends downward in the center of the cap 6, and the columnar portion 8 is fitted into the pole 3 of the main body portion to combine the cover portion and the main body portion. Further, when the fragrance is not used, the cover 5 is a portion indicated by a symbol b in FIG. 3, and an annular protrusion provided on the cover 5 is fitted in an annular groove provided on the main body 2. The inside of the container is sealed.

FIG. 5 is an enlarged view showing details of the pole 3 attached to the center of the main body 2. As can be seen from FIG. 5, two spiral grooves 9, 9 ′ are provided on the hollow inner peripheral surface of the pole 3 so as to face oppositely on the circumference. The inclination angle of the groove slope of the spiral groove is set to be relatively large so that the maximum exposure amount of the fragrance can be obtained by one rotation (the method for setting the exposure amount of the fragrance will be described later).

  FIG. 4 is a detailed view of the cap 6. The columnar portion 8, which may be hollow or solid, of the cap 6 is provided with ridge portions 10, 10 ′ inclined at two locations along the outer periphery of the columnar portion 8. These protrusions 10 and 10 ′ are adapted to fit into spiral grooves 9 and 9 ′ provided on the inner periphery of the pole 3. Accordingly, they are arranged at opposite positions on the outer periphery of the columnar portion 8 (positions spaced apart from each other by 180 °), and the inclination angle is equal to the inclination angle of the groove slopes of the spiral grooves 9, 9 '.

  Next, a method for assembling the present fragrance container will be described. At the time of assembly, first, the lower end portion of the pole 3 is fitted to the bottom portion of the main body 2. Next, the cover is fitted, and the aromatic liquid is poured into the gap between the pole and the cover, cooled and solidified to form a gel. On the other hand, the cover 6 is formed by fitting the cap 6 into the cover 5. Next, the columnar portion 8 of the cap 6 is pushed into the pole 3 of the main body portion from above. The cap 6 is made of a resin having elasticity (for example, polypropylene), while the pole 3 is also made of a resin having the same elasticity and elastically deforming due to the elasticity of both and the slipperiness peculiar to the resin. Thus, the columnar portion 8 is press-fitted into the pole 3. When the protrusions 10 and 10 'on the columnar part 8 reach the position of the spiral grooves 9 and 9', the protrusions 10 and 10 'are inserted into the corresponding spiral grooves 9 and 9' by elasticity. To do. The protrusions 10 and 10 ′ on the columnar portion 8 are elastically attached radially outward so as to elastically abut against the bottom surface of the spiral groove even in a state of being fitted in the spiral grooves 9 and 9 ′. The radial dimension is such that it is biased. Subsequently, when the cover portion is further twisted, the protrusions 10 and 10 ′ of the cap 6 enter along the spiral grooves 9 and 9 ′, and finally the cover 5 and the cap 6 are fitted together. The inside of the container is sealed to complete the fragrance assembly (as shown in FIGS. 1 and 3). When the cover portion is twisted, the cover portion enters by the protrusions 10 and 10 ′ of the cap 6 entering along the spiral grooves 9 and 9 ′.

  Next, a method for using a fragrance using this fragrance container will be described. The user of the fragrance removes the outer wrapping for preventing volatilization, and then twists the entire cover portion composed of the cover 5 and the cap 6 in the direction opposite to that at the time of assembly, so that the space between the cover 5 and the body 2 is Remove the mating. Then, the protrusions 10 and 10 'of the cap 6 slide up the groove slope of the spiral groove along the spiral grooves 9 and 9', the cover part rises from the main body part, and the lower end edge of the cover 5 and the upper end of the main body 2 The gap between the edges gradually opens, and the gel-like fragrance held on the main body is exposed (see FIG. 2). When the degree of exposure of the fragrance reaches a desired position, the user stops the rotation of the cover portion. And the hook part 7 of the cap 6 is suspended and installed in an appropriate place. In the state where the fragrance container is suspended, the weight of the fragrance and the main body part is applied to the cover part, and the upper end surfaces of the protrusions 10 and 10 'of the cap 6 come into contact with the upper groove slopes of the spiral grooves 9 and 9'. The frictional force of these contact surfaces and the frictional force due to the elastic biasing force in the radial direction of the ridges 10 and 10 ′ against the bottom surface of the spiral groove are held and set at the exposure position where the fragrance is set. The sustained release amount is maintained.

  Thus, in this embodiment, a desired fragrance exposure amount can be set with a rotation amount smaller than that of the conventional one, and two spiral grooves arranged opposite to each other and the corresponding protrusions. Due to the frictional force and the elastic biasing force, the set exposure amount of the fragrance is kept constant without changing over time. In particular, the weight of the main body portion containing the fragrance as in the present embodiment also functions effectively even in a suspended fragrance assembly that is applied to the cover portion.

  The principle of the present invention can be used effectively not only in a suspended-type fragrance container but also in a mounting-type fragrance container. Moreover, it can be effectively applied not only to the fragrance container but also to a sustained-release drug container by the same method of use.

FIG. 1 is a perspective view showing a suspended state of the suspending fragrance container 1 according to the present embodiment before use. FIG. 2 is a perspective view showing an opened state when the fragrance container 1 is used. FIG. 3 is a cross-sectional view of the fragrance container 1 in the state shown in FIG. FIG. 4 is a detailed view of the cap 6. FIG. 5 is an enlarged view showing details of the pole 3 attached to the center of the main body 2.
