Description

  The present invention relates to an injection container for injecting contents through a nozzle.

  In a conventional jetting container, a rotating head is provided on a container body filled with a liquid content, and a circumferential groove is formed on the outer peripheral surface of a sliding member that can be raised and lowered relative to the rotating head. There is one in which the content liquid in the container main body is sprayed through a nozzle by moving the piston suspended from the sliding member up and down by being guided by the ball member placed on (see, for example, Patent Document 1).

Japanese Patent Publication No.54-25245

  However, since the conventional injection container directly pressurizes and sprays the content liquid, the injection range is limited, and it is difficult to inject over a wide range. Moreover, when spraying a liquid directly, it may fall by the dead weight and may adhere to circumference | surroundings.

  An object of the present invention is to provide a novel spray container that can spray the contents over a wide range and does not adhere to the surroundings due to natural fall.

The present invention relates to an expandable / contractible container body having a mouth tube portion for sending air to a nozzle member, a base member having a recessed bottom wall that allows the container body to extend inside the tubular portion, and a shoulder of the container body A rotating member whose inner peripheral wall hangs together with an outer cylindrical wall that is rotatably supported by the cylindrical portion of the base member from the top wall that holds the portion, and a bottom wall that holds the lower end of the container body. A sleeve member that can move up and down between the inner cylinder wall and the outer cylinder wall, and an elastic member that is disposed between the recess bottom wall of the base member and the bottom wall of the sleeve member and biases the sleeve member upward And a ball member that rotatably holds between the cylindrical portion of the base member and the sleeve member, and a vaporizing element that is housed in at least one of the nozzle member and the container body and vaporizes components,
While providing a step portion for placing the ball member on the inner peripheral surface of the cylindrical portion of the base member,
Provided on the outer peripheral surface of the sleeve member is a circumferential groove that causes rotation of the sleeve member starting from the ball member;
The circumferential groove includes an inclined groove for lowering the sleeve member against the urging force of the elastic member, and a groove for raising the sleeve member by the urging force of the elastic member through the inclined groove.
By rotating the rotating member relative to the base member, the air sucked by the extension of the container body is sent to the nozzle member by the compression of the container body.

  Examples of the expandable / contractible container body include a bellows container having a bellows-like body, a bag-like container formed in a thin wall, and the like. Examples of the vaporizing element include an impregnated material obtained by immersing a liquid in a woven fabric, a non-woven fabric, a porous material, or the like, and a sublimation material that directly vaporizes from a solid.

  In the present invention, it is preferable that the nozzle member is provided with a check valve that allows the inside of the container body to communicate with the outside world by being pushed down, while preventing the introduction of outside air by releasing the pushing.

  In the present invention, if the rotating member is rotated with respect to the base member, the container main body also extends following the lowering of the sleeve member. When the rotating member is further rotated, the sleeve member rises by the biasing force of the elastic member, and thus the container body contracts in synchronization with the raising of the sleeve member. That is, by rotating the rotating member with respect to the base member, the container body expands and contracts in synchronization with the sleeve member moving up and down along the circumferential groove starting from the ball member. For this reason, if the vaporizing element is stored in the nozzle member or the container main body, the vaporized component can be injected through the nozzle member together with the air sent out by the expansion and contraction of the container main body. In this case, since the vaporized component is injected as it is, in addition to the injection, for example, the component can be diffused over a wide range in the room by being placed on the airflow in the room. Moreover, since the injected component is vaporized, it does not adhere to the surroundings by the natural fall of the contents.

  Therefore, according to the present invention, the contents can be sprayed over a wide range and do not adhere to the surroundings due to natural fall. Moreover, since the extendable container main body is used for sending out air, it is possible to cope with a large volume injection to a small volume injection.

It is a fragmentary sectional view which shows the initial state or injection state of the fragrance | flavor injection container which is one form of the injection container which is this invention. It is a fragmentary sectional view showing the state just before injection of the form. (A) is a perspective view which shows typically the sleeve member based on the form, (b) is principal part sectional drawing which shows one form of a nozzle member. It is a perspective view which shows the container main body based on the form typically with a sleeve member, Comprising: (a) is the state which the container main body contracted, (b) shows the state which the container main body expanded. It is principal part sectional drawing which shows the other form of the nozzle member based on the form.

  Hereinafter, a fragrance injection container 1 according to an embodiment of the present invention will be described in detail with reference to the drawings.

  In FIG. 1, reference numeral 2 denotes an extendable container body that sends air to the nozzle member 3. The container body 2 has a mouth tube portion 2a for sending out air, and is connected to an expandable / contractible bellows-like body portion 2c via a shoulder portion 2b. The trunk portion 2c is connected to the bottom portion 2d via an annular groove portion 2e extending around the injection container axis O (circumferential direction). The container body 2 can be integrally formed with a flexible synthetic resin, for example.

The nozzle member 3 is fixed to the mouth tube portion 2a via the cap C. Cap C is configured to seal the mouth tube portion 2a, a check valve V ₁ is provided. The check valve V ₁ allows outside air to be introduced into the internal space S ₁ of the container body 2, while preventing air from being discharged from the internal space S 1.

Reference numeral 4 denotes a base member. The base member 4 has a bottom wall 4b at the inner lower end of the cylindrical portion 4a, and a recess D that allows expansion of the container body 2 is formed. The recess D is provided with an annular step 4c extending in the circumferential direction. Thus, between the cylindrical portion 4a and the step 4c, connecting each other as well as constituting the upper body portion 4h ₁ of larger diameter, between the bottom wall 4b and the step 4c, under the small-diameter connecting each other constituting the side body portion 4h _2. Further, the base member 4 can be raised by a cylindrical leg portion 4d that hangs down integrally from the cylindrical portion 4a.

  Reference numeral 5 denotes a rotating member. The rotating member 5 has a top wall 5a in which an opening through which the nozzle member 3 passes is formed together with the mouth tube portion 2a of the container body 2. The top wall 5 a holds the shoulder 2 b of the container body 2. Further, from the top wall 5a, the inner cylinder wall 5c hangs down together with the outer cylinder wall 5b at an interval around the injection container axis O.

  The lower end portion of the outer cylindrical wall 5b surrounds the cylindrical portion 4a of the base member 4, and is slidably held by the cylindrical portion 4a. Thereby, the rotation member 5 can be rotated clockwise or counterclockwise around the bottle axis O.

  An annular protrusion 5e extending in the circumferential direction is provided inside the lower end portion of the outer cylindrical wall 5b. The base member 4 is provided with an annular protrusion 4e extending in the circumferential direction outside the upper end portion of the cylindrical portion 4a. In this embodiment, the protrusion 5e is locked to the protrusion 4e, so that the rotating member 5 is retained.

  Reference numeral 6 denotes a sleeve member. The sleeve member 6 has a sleeve main body 6a disposed between the outer cylinder wall 5b and the inner cylinder wall 5c of the rotating member 5. A plurality of protrusions 6p are provided on the inner side of the sleeve body 6a at intervals in the circumferential direction. In addition, the rotating member 5 is provided with a plurality of protrusions 2p on the outer side of the inner cylinder portion 5c with an interval in the circumferential direction. The protrusion 6p and the protrusion 2p are spline-fitted with each other. As a result, the sleeve member 6 can move up and down along the injection container axis O, and can rotate integrally with the rotating member 5 without idling.

  In addition, a bottom wall 6b that holds the lower end portion (bottom wall 2d) of the container body 2 is integrally provided at the lower end portion of the sleeve body 6a. The bottom wall 6b is formed with an opening through which the bottom wall 2d of the container body 2 passes. The bottom wall edge 6e that forms the opening is fitted into the annular groove 2e of the container body 2.

  Reference numeral 7 denotes an elastic member typified by a return spring. The elastic member 7 is disposed between the concave bottom wall 4 b of the base member 4 and the bottom wall 6 b of the sleeve member 6. The elastic member 7 urges the sleeve member 6 upward toward the rotating member 5 as shown in FIG.

  Reference numeral 8 denotes a ball member. The ball member 8 is disposed at two positions facing each other across the injection container axis O. The ball member 8 rotatably holds between the cylindrical portion 4a of the base member 4 and the sleeve member 6.

  A step portion 4 s is provided on the inner peripheral surface of the tubular portion 4 a of the base member 4. The step 4s can place the ball member 8 rotatably. As shown in FIG. 3A, the sleeve member 6 is provided with a circumferential groove 6g that circulates around the injection container axis O on the outer peripheral surface of the sleeve body 6a. The circumferential groove 6g can fit the ball member 8 rotatably. As a result, the circumferential groove 6 g causes the sleeve member 6 starting from the ball member 8 to rotate around the injection container axis O together with the step 4 s of the base member 4.

The circumferential groove 6g includes an inclined groove 6g ₁ and a vertical groove 6g ₂ communicating with the inclined groove 6g ₁ . Ball member 8, because the height and circumferential position is fixed by the stepped portion 4s of the base member 4, the inclined groove 6 g ₁ shows the change from FIGS. 4 (a) to FIG. (B) as such, functions as a groove for lowering against the sleeve member 6 to the urging force of the elastic member 5, the longitudinal grooves 6 g _2, as shown as a change from FIG. 4 (b) to FIG. (a) The sleeve member 6 functions as a groove for ascending by the urging force of the elastic member 5. The vertical groove 6g ₂ can be replaced with the inclined groove 6g ₁ .

  Further, the sleeve member 6 has a top dead center at a position where the upper end of the sleeve body 6a is in contact with the top wall 5a of the rotating member 5, as shown in FIG. A position in contact with the step 4c of the base member 2 is defined as a bottom dead center.

  In this embodiment, the container body 2 is configured such that the height (length) from the shoulder 2b to the annular groove 2e is higher than the height when the sleeve member 6 is lowered to the bottom dead center. Thus, the container body 2 is assembled between the rotating member 5 and the sleeve member 6 in a compressed state. For this reason, the annular groove 2e of the container body 2 is fitted to the bottom wall edge 6e of the sleeve member 6, whereby the lower end of the container body 2 is fixed to the sleeve member 6 and the shoulder 2b of the container body 2 is fixed. Is held by the top wall 5a by pressing against the top wall 5a of the rotating member 5.

  The container body 2 can also be fixed to the sleeve member 6 by means such as adhesion. Moreover, the shoulder part 2b can provide an annular groove part like the lower end part of the container main body 2, and can be fitted to the edge part which forms the opening part of the top wall 5a.

Therefore, when the sleeve member 6 rotates the rotating member 5 clockwise around the bottle axis O with respect to the base member 4 when the injection container 1 is viewed from above, the same figure from FIG. As shown as a change to (b), the check valve V1 introduces outside air in synchronism with the sleeve member 6 descending along the inclined groove 6g ₁ against the urging force of the elastic member 7. The container body 2 is also extended. As further shown in upper end drawing of longitudinal grooves 6 g _2, shown as a change in is rotated the rotary member 5 until the position of the ball member 8, from FIG. (B) to FIG. (A) as described above, in synchronism with the sleeve member 6 is raised along the longitudinal grooves 6 g ₂ by the urging force of the elastic member 7, also the container main body 2 while compressing the air in the space S1 in the check valve V1 is closed Shrink. Thereby, as shown in FIG. 1 through the change from FIG. 1 to FIG. 2, the air sucked into the internal space S <b> 1 by the extension of the container body 2 can be sent to the nozzle member 3 by the compression of the container body 2.

  In this way, by rotating the rotating member 5 with respect to the base member 4, the sleeve member 6 starts to move up and down along the circumferential groove 6g starting from the ball member 8, and the internal space of the container body 2 is synchronized. Air is sucked into S 1 and sent out to the nozzle member 3. For this reason, if the vaporizing element E which vaporizes a component is stored in the nozzle member 3 or the container main body 2, the vaporized component can be injected through the nozzle member 3 together with the air sent out by the expansion and contraction of the container main body 2. . In this case, since the vaporized component is injected as it is, in addition to the injection, for example, the component can be diffused over a wide range in the room by being placed on the airflow in the room. Moreover, since the injected component is vaporized, it does not adhere to the surroundings by the natural fall of the contents.

  Therefore, according to the present invention, the contents can be sprayed over a wide range and do not adhere to the surroundings due to natural fall. Moreover, since the container body 2 that can be expanded and contracted is used for sending out air, it is possible to cope with a large volume injection to a small volume injection.

  By the way, as in the above-described embodiment, the container body 2 can be extended and compressed only by operating the rotating member 5, and air can be sent out along with the compression. However, in this case, since the outside air is introduced and discharged through the nozzle member 3, the adjustment is complicated.

  For this reason, it is preferable that the nozzle member includes a function of preventing the intake of outside air while allowing air to be sent out from the container body 2.

  FIG. 3B shows an openable nozzle member 30 (hereinafter, “nozzle member 30”), which is another embodiment of the nozzle member according to the present invention. The nozzle member 30 (hereinafter referred to as “nozzle member 30”) is supported by the head main body 31, the nozzle 32, the nozzle pin 33, the spring 34, the joint 35, the support wall 36 fixed to the head main body 31, and the support wall 36 so as to be swingable. And a swing lever 37 and a stem 38 for supporting the nozzle pin 33.

  The nozzle member 30 can be sent to the compressed air in the container body 2 through the spout A by moving the head body 31 up and down by being attached to the cap C via the stem 30.

  Further, when the head body 31 is pushed down to be lowered with respect to the joint 35, the swing lever 37 tilts rearward about the support wall 36 around the joint 35 as an action point, so that the ejection port of the head body 31 is restored. A is released when the nozzle pin 33 moves backward against the urging force of the spring 34.

  Next, when the depression of the head main body 31 is released, the nozzle pin 33 seals the ejection port A by the urging force (restoring force) from the spring 34 and returns the head main body 31 to the initial position.

  Thereby, the nozzle member 30 can be opened only when the air in the container body 2 is sent out. That is, if the nozzle member 30 is used, the component vaporized from the vaporizing element E can be injected through the injection port A of the nozzle member 3 in response to the pushing of the nozzle member 3 after rotating the rotating member 5.

  In the present embodiment, the vaporizing element E can be disposed in the passage of the stem 38, for example. In this case, the vaporizing element E can be arranged in advance at the time of assembly before shipment, or can be newly arranged separately by removing it from the cap C after use. Moreover, when it arrange | positions beforehand in the stem 38, the liquid containing the vaporization component can be supplied from the stem 38 by arrange | positioning only an impregnation member.

  Moreover, according to this invention, a nozzle member can also be comprised as shown in FIG. The nozzle member 40 in the figure is held so that it can be pushed into the cap C by the urging force (restoring force) of the elastic member 9 typified by a return spring. The cap C is provided with a check valve 10. The check valve 10 has a valve body 10a, and the valve body 10a is held by the cap C via a plurality of connecting pieces 10b.

  The nozzle member 40 has a nozzle body 41. A recess is formed in the nozzle body 41, and the upper end opening of the recess is closed by a lid 42, thereby forming a storage space S2 for the vaporizing element E inside the nozzle body 41. The lid body 42 is integrally connected to the nozzle body 41 via a hinge 43, for example.

  In addition, a pedestal 44 on which the vaporizing element E is placed is provided integrally with the nozzle body 41 via a partition wall 45. A plurality of through holes 45 a are formed in the partition wall 45. Further, the shaft 46 hangs integrally with the partition wall 45. Reference numeral 47 denotes a bulging portion that is provided integrally with the lid 42 and that holds the vaporizing element E in contact with the vaporizing element E. The bulging portion 47 can be omitted.

  When the lid 42 is pushed in from the direction of the arrow, the nozzle member 40 descends against the urging force of the elastic member 9 so that the shaft 46 presses the valve body 10a of the check valve 10 and connects the valve body 10a. It can be opened against the tension of the piece 10b. Thus, if the nozzle member 40 is pushed down after rotating the rotating member 5, the component vaporized from the vaporizing element E rides on the air sent out from the container body 2 through the plurality of through holes 45 a and passes through the injection port A. Can be injected. When the pushing of the lid 42 is released, the restoring force of the elastic member 9 returns the nozzle member 40 to the initial position, and the valve body 10a is closed to seal the inside of the container body 2.

  The above description only shows one embodiment of the present invention, and various modifications can be made within the scope of the claims. The container body 2 is not limited to the bellows container as in the present embodiment, and for example, a bag-like container formed in a thin wall can be adopted. Further, examples of the vaporizing element E include an impregnated material obtained by immersing a liquid in a woven fabric, a non-woven fabric, a porous material, or the like, and a sublimation material that directly vaporizes from a solid.

  The present invention is not limited to a fragrance injection container, and can be applied to a medicine injection container such as a deodorant, insect repellent, oral medicine, or nasal spray.
