  The container of Patent Document 1 has a support member and a dispensing mechanism, and disposing the entire container after using up the content liquid in the container body is a waste of resources. Although it is desirable to replace the container body with a new container body after use, a device for easily replacing the container body is not particularly disclosed.

  An object of the present invention is to propose a two-liquid dispensing container that can easily perform a refilling operation of a container body.

The first means includes a pair of left and right container bodies 2 that stand in parallel with each other and stand up the mouth-and-neck portion 4;
Including a support base 8 having a support hole 10 fitted to the outer surface of the mouth-and-neck portion 4 of the container body, and a support member 6 having an outer peripheral wall 16 raised from the outer peripheral portion of the support base
A two-liquid dispensing container that is fitted in the outer peripheral wall 16 and includes a dispensing mechanism 30 that sucks up the contents from the mouth and neck of each container body, mixes them, and dispenses them from the nozzle 58. ,
The pouring mechanism 30 has a pair of left and right leg cylinders 46 that are fitted to the inner surface side of the mouth neck portion 4 of each container body and communicate with the nozzle 58.
An elastic push-up member 60 is interposed between the lower surface of the pouring mechanism 30 excluding these leg cylinders and the support base 8, and a push button 70 for pushing the elastic push-up member inward is provided. The push-up member is bent upward to push up the dispensing mechanism so that the leg tube 46 can be detached from the mouth / neck portion 4 of the container body.

  This means proposes that an elastic push-up member 60 is provided between the support base 8 supporting the two container bodies and the extraction mechanism 30 as shown in FIG. Thus, by pushing the push button 70 of the elastic push-up member 60, the dispensing mechanism can be detached from the mouth and neck of the container body.

  The “elastic push-up member” is a member that bends upward by pushing the push button and pushes up the dispensing mechanism. “Bending upward” includes bending into a “<” shape as shown in FIG. 10 and bending and deforming into a bow shape as a whole. It is desirable to provide the push button so that it can be pushed in the left-right direction.

  The second means includes the first means, and the elastic push-up member 60 has a ring body 62 that is long in the left-right direction when viewed from above. The deforming part 62a is more easily deformed than the remaining part 62b of the body.

  This means proposes that the intermediate part in the left-right direction of the ring body 62 of the elastic push-up member 60 is a deformable part 62a that is easily deformed as shown in FIG. This is for elastically restoring the original position after the deformation, and for preventing unexpected deformation of the elastic push-up member by locally deforming. In order to easily deform the intermediate portion, the portion may be thinner than the remaining portion or may be formed in advance in a curved shape that is easy to deform.

  The third means includes the second means, and the deforming portion 62a is shaped in advance so as to protrude into the space S between the two leg cylinders 48 inward in the front-rear direction.

  This means proposes that the deformation portion is provided so as to protrude into the space between the two leg tubes as shown in FIG. Since the deformation allowance of the deformation portion becomes long, the pushing operation is facilitated, and the space between the leg cylinders can be utilized as a storage space for the deformation portion.

The fourth means includes the second means or the third means, and one of the corresponding portions of the support base 8 and the ring body 62 has a guide slope 14 inclined from the front side, and the other, Sliding convex portions 68 that can be pressed against the guide slope by pressing the push button are formed.

  This means proposes that the guide slope 14 and the sliding protrusion 68 are formed on the support base and the ring body as shown in FIG. A sliding convex part slides on a guide slope, and a ring body can be pushed up and can be forcedly deformed.

The fifth means includes any one of the second means to the fourth means, and the pouring mechanism 30 is fitted to the outer peripheral wall 16 and is fitted to the outer surfaces of the pair of leg tubes 46. An intermediate plug-shaped connector 32 having a fitting hole 36 is provided, and the lower surface of the connector is placed on the upper surface of the ring body.

  As shown in FIG. 4, this means proposes a connector 32 having a fitting hole 36 fitted into the outer wall of the pair of leg tubes 46 as well as being fitted into the outer peripheral wall. This is because the leg cylinders are fixed to each other with a connector so that both leg cylinders are lifted and lowered equally with respect to the outer peripheral wall.

The sixth means has third means, and the connector 32 has a connecting cylinder 38 fitted to the inner surface of the outer peripheral wall 16.
When the pouring mechanism 30 is pushed up by the push button 70 being pushed into the connecting cylinder 38 and the outer peripheral wall 16, the push-up state can be held so that the push-up state can be held and the lock projections 40 are engaged with each other. A recess 22 is provided.

  In this means, for example, as shown in FIG. 11, the locking projection 40 is locked to the locking recess 22, thereby preventing the dispensing mechanism from being unexpectedly lowered during the container body replacement operation.

  According to the first aspect of the invention, the elastic push-up member 60 is used to push up the pouring mechanism 30, so that the leg tube 46 of the pouring mechanism and the mouth and neck of the container body are separated. It becomes easy to perform the refilling operation of the container body.

  According to the invention relating to the second means, since the elastic push-up member 60 includes the ring body 62 having the intermediate portion in the left-right direction as the deformation portion 62a, the elastic push-up member 60 is easily deformed to push up the dispensing mechanism 30.

  According to the invention relating to the third means, since the deforming portion 62a is shaped in advance so as to protrude inward in the front-rear direction, the deformation allowance becomes long and the pushing operation becomes easy.

  According to the fourth aspect of the invention, since the guide slope 14 and the sliding protrusion 68 that are engaged with each other are provided at corresponding portions of the support base 8 and the ring body, the pushing-out mechanism 30 can be pushed up more reliably. become.

  According to the invention relating to the fifth means, the middle plug-shaped coupling tool 32 fitted to the pair of leg tubes 46 of the pouring mechanism is fitted into the outer peripheral wall 16, and this coupling tool is mounted on the upper surface of the ring body. Therefore, the push-up force for each leg tube can be equalized.

  According to the invention relating to the sixth means, the pushed-up state of the pouring mechanism 30 is maintained by the locking projections and the locking recesses provided on the connecting cylinder 38 and the outer peripheral wall 16 of the support base. Easy to replace.

  1 to 12 show a two-liquid dispensing container according to the first embodiment of the present invention. As shown in FIG. 4, this container includes two container bodies 2, a support member 6, a dispensing mechanism 30, and an elastic push-up member 60. These members can be formed of a synthetic resin unless otherwise specified.

  The container body 2 erects the mouth-and-neck portion 4 from the upper end of the bottomed cylindrical wall via the shoulder portion.

  The support member 6 has a support base 8 that is long in the left-right direction and has a support hole 10 for fitting the outer surface of the mouth-and-neck portion 4. In the illustrated example, a bottomed cylindrical case body 7 is connected to the outer periphery of the lower surface of the support base 8. The front half of the cylindrical wall of the case body is a lid 7a pivotally attached to the rear half, and a lock means 7b that also serves as a finger hook is provided on the opposite side of the pivot.

In the illustrated example, a double cylindrical holding means 12 is provided at the tip of the inward flange protruding from the lower edge of the support hole 10, and the mouth and neck 4 is held between the double cylinders. Inside of the inner cylindrical portion of the clamping means, provided wicking valve v _1.

  For example, as shown in FIG. 10, shallow depressions are provided on both the front and rear sides of each support hole 10 on the upper surface of the support base 8, and a guide slope 14 that inclines inward in the left-right direction when viewed from the front. Is formed.

  A straight cylindrical outer peripheral wall 16 is erected from the outer edge of the upper surface of the support base 8. As shown in FIG. 5, the upper part of the left and right intermediate portion of the outer peripheral wall 16 is a thin portion 18 that is recessed inwardly. A locking recess 22 is formed on the inner surface of the thin portion to hold a locking projection described later, and a storage recess 20 for the locking projection is provided slightly below the locking recess. The storage recess 20 has an upward and inwardly inclined surface.

  The dispensing mechanism 30 includes a base portion 30a attached to the support member 6 and a movable portion 30b that can be raised and lowered with respect to the base portion. The base 30 a can be formed by the connector 32 and the cylindrical member 44. In the preferred illustrated example, the dispensing mechanism 30 is symmetric in the left-right direction, and is substantially symmetric in the front-rear direction, except for some of the nozzles described later.

  The connector 32 is a substantially plug-like member fitted in the outer peripheral wall 16, and opens two places on the horizontal substrate 34, and the inner surface of the fitting cylinder 42 rising from each opening will be described later. This is a fitting hole 36 to the leg tube.

  A connecting cylinder 38 for fitting to the outer peripheral wall is erected from the outer edge of the substrate 34, and the outer surface of the connecting cylinder is engaged with the locking recess when the pouring mechanism 30 shown in FIG. 11 is pushed up. A locking projection 40 is provided. The locking projection is in the storage recess 20 in a normal state where the dispensing mechanism is lowered. Further, a retaining projection 41 that engages with the locking recess in this normal state is provided above the locking projection.

  The cylindrical member 44 is a member that forms a continuous flow path from the two neck portions 4 to the movable portion 30b. In the illustrated example, the cylindrical member 44 is fitted and fixed in the fitting hole 36 of the connector. It is formed by a pump cylinder 48 and a leg cylinder 46 having a small diameter in the lower half part fitted to the outer surface of the pump cylinder and the inner surface side of the mouth neck portion 4. The pump cylinder 48 is a double cylinder having a continuous lower end, and is provided with a retaining cylinder portion 50 that is folded back into the inner cylinder 48a from between the inner cylinder 48a and the outer cylinder 48b.

  The movable portion 30b includes a pair of liquid introduction pipes 56 inserted into the inner cylinder 48a of the pump cylinder, and a flow path 54 for joining these liquid introduction pipes formed below the top plate of the cover cylinder 52. The nozzle 58 communicates forward of the cover cylinder. The movable part is biased upward.

  As shown in FIG. 4, the elastic push-up member 60 is a substantially flat member that is interposed between the support base 8 and the pouring mechanism 30, and is bent by inward pushing as shown in FIG. It is strong enough to push up the mechanism.

  As shown in FIG. 3, the illustrated elastic push-up member 60 has a ring body 62 that is long to the left and right and push buttons 70 that protrude from both the left and right sides of the ring body. The leg tube 46 is formed so that it can be inserted. Further, in order to allow the push button 70 to be pushed in, a compression allowance d of the ring body is provided between the leg tube and the edge in the left-right direction of the ring hole.

  The ring hole 64 is preferably an oval or rectangular shape having a constant width in the front-rear direction and having a front-rear width corresponding to the outer diameter of the leg tube.

  The push button 70 protrudes outward of the container through the through holes 17 on both the left and right sides of the outer peripheral wall 16. In this illustrated example, the ring body for deformation and the push button for operation are integrally formed, so that, for example, a simple structure can be achieved as compared with the case where the push button is formed on a part of the support member.

The intermediate part in the left-right direction of the ring body 62 is formed in a pair of front and rear deformation parts 62a that are more easily compressed and deformed in the left-right direction than the rest of the ring body. This is to prevent unexpected deformation.
In the illustrated example, the deforming portion is formed into an easily deformable spring that is bent in a substantially Ω shape in advance, and the rim-shaped portion 66 of the ring body excluding the deforming portion is thicker than the deforming portion. As a part. However, the deforming portion 62a may be pre-curved but not thin, or thin but not pre-curved.

  Further, in the illustrated example, as shown in FIG. 7, there is a step 67 between the outer peripheral portion and the inner peripheral portion of the ring body, and the lower end of the connecting tube protruding downward from the bottom surface of the connector fitting fits into the step 67. (See FIG. 4).

  A sliding projection 68 is attached to the lower surface of the rim-shaped portion 66 of the ring body 62. The sliding projection 68 is arranged so as to contact or be close to the guide slope 14 of the support base, and is provided so as to ride on the guide slope and push the ring body 62 upward when the push button 70 is pushed. It is preferable that the sliding convex portion is formed to have an inclined surface corresponding to the guide slope. Unlike the illustrated example, a recess with a guide slope may be provided on the ring body side, and a sliding projection may be provided on the support base side.

In the preferred illustrated embodiment, the elastic lifting member 62 is substantially axisymmetrical with respect to the central axis O ₂ of the center axis O ₁ and the front-rear direction in the horizontal direction as shown in FIG. 3, and a pair of front and rear deforming portion 62a In addition, the strength and elasticity at the symmetrical positions including are uniformly formed. The sliding protrusions 68 are also provided at four positions symmetrically on the right front, left front, right rear, and left rear of the ring body, and have substantially the same configuration so that the same level of lifting force can be obtained at each of these positions. Forming. Thereby, it is possible to push up the pouring mechanism 30 equally.

  In the above configuration, when the movable part 30 b of the dispensing mechanism 30 is pushed down, the contents of each container body 2 are sucked up by the pump cylinder, mixed in the gap 54, and dispensed as a mixed liquid from the nozzle 58.

  When the contents in the container body 2 are used up, the push button 70 of the elastic push-up member 60 may be pushed inward as indicated by an arrow in FIG. Then, the sliding convex portion 68 attached to the lower surface of the rim-shaped portion rides on the guide slope 14 of the engaging concave portion. As a result, the deformation portion 62a of the elastic push-up member is easier to bend than the rim-like portion, so that the elastic push-up member 60 as a whole has a "<" shape as shown in FIG. Deform. As a result, the dispensing mechanism 30 is pushed up, and the lower portion of the leg tube 46 is detached from the mouth / neck portion 4 of the container body.

  At this time, the coupling tool 32 is fixed to the leg cylinders 46 of the pouring mechanism relative to each other, and the coupling cylinder 38 of the coupling tool 32 is fitted to the outer peripheral wall, so that the two leg cylinders are pushed up. Variation in quantity can be reduced. The variation is further reduced by arranging the sliding protrusion and the guide slope at symmetrical positions in the front-rear and left-right directions.

  When the dispensing mechanism 30 is pushed up, the locking projection 40 slides on the inclined surface in the storage recess 20 as shown in FIG. 8 (see FIG. 8B) and locks in the locking recess 22. Thereby, even if a hand is released from pushbutton 70, the raising state of pouring mechanism 30 can be maintained.

  In this state, the lid 70a of the case body 70 is opened, the mouth / neck portion of the container body 2 is pulled out from the support hole 10 of the support base 8, and a new container body is mounted.
