Description

  TECHNICAL FIELD The present invention relates to a fluid discharge container for storing a storage bag for storing a fluid and discharging the fluid in the storage bag to the outside.

  2. Description of the Related Art Conventionally, fluid discharge containers that store various fluids such as a perm solution, a shampoo, a rinse, a body soap, a disinfectant, a seasoning, and the like inside a container and discharge the fluid to the outside of the container have been widely used. Generally, the fluid discharge container stores the fluid directly inside the container, sucks the fluid inside the container by a discharge mechanism such as a hand-operated pump or a trigger pump provided at the upper part of the container, and sends the fluid to the outside of the container. It discharges.

  Such a fluid discharge container was discarded together with the container when the fluid inside the container was exhausted due to use. However, from the viewpoint of ecology (natural environment protection), when the fluid inside the container was exhausted, it was stored in a refill bag. The same fluid is transferred to the inside of the fluid discharge container. However, when the fluid is transferred from the bag to the container as described above, since the fluid comes into contact with air outside the bag or the container, the quality of the fluid may be deteriorated.

  Therefore, recently, a fluid discharge container that stores a storage bag in which a fluid is stored, instead of directly storing the fluid in the container, and discharges the fluid in the storage bag to the outside has attracted attention. . More specifically, the fluid discharge container is inserted into a storage bag having a female member provided with a through hole at an upper portion, a lower container storing the storage bag, and a female member of the storage bag. An upper container provided with a discharge mechanism having a male member. According to this, the storage bag storing the fluid is stored inside the lower container, and the upper container and the lower container are connected while inserting the male member of the discharge mechanism into the through hole of the female member of the storage bag. With such a structure, the fluid stored in the storage bag can be prevented from contacting the outside air.

JP 2014-65535 A Re-published 2017-061060

  However, in this fluid discharge container, the male member of the discharge mechanism is usually inserted into the through hole of the female member of the storage bag in a tightly contacted state so that the fluid stored in the storage bag does not come into contact with air. . For this reason, when replacing the storage bag stored in the container, when the upper container provided with the discharge mechanism is separated from the lower container, the lower container is inserted with the storage bag inserted into the male member of the discharge mechanism. Therefore, since the male member of the ejection mechanism must be pulled out from the female member of the storage bag, there is a problem that the replacement work of the storage bag is troublesome for general consumers.

  Originally, a fluid ejection container for fixing the female member of the storage bag to a fixing member provided at the opening of the lower container is also known (see Patent Documents 1 and 2). It is difficult to understand that the member is fixed to the fixing member of the lower container, and in some cases, the operation of replacing the storage bag becomes complicated. In addition, due to the structure in which the female member of the storage bag is fixed to the fixing member of the lower container, an opening must be provided on the side surface of the lower container, and the degree of freedom in container design may be reduced.

  The present invention has been made in view of the above-described problems, and has as its object to provide a fluid discharge container that allows a general consumer to reliably replace a storage bag by a simple operation.

  In order to achieve the above object, the present invention is a fluid discharge container for storing a storage bag for storing a fluid and discharging the fluid in the storage bag to the outside, wherein a female member provided with a through hole is provided. A storage container having an opening at the top thereof, an opening formed therein, a lower container storing the storage bag from the opening, and a discharge mechanism having a male member inserted into the through hole of the storage bag. An upper container detachably provided in the lower container, and an inner lid fitted into an opening of the lower container, wherein the inner lid is vertically movable in an inner space of the upper container. When the upper container and the lower container are separated from each other, the upper container is separated from the lower container when the upper container and the lower container are separated from each other. After moving relatively downward, the upper container On the other hand, when the upper container and the lower container are combined with each other, as the upper container approaches the lower container, the inner space of the upper container is relatively raised. After moving, it is locked downward by the upper container.

  According to this, when the upper container and the lower container are separated, the inner lid moves relatively downward in the inner space of the upper container as the upper container separates from the lower container. Accordingly, the male member of the ejection mechanism can be smoothly pulled out from the female member of the storage bag while holding the storage bag with the inner lid in order to maintain the state in which the inner lid is fitted into the opening of the lower container. After that, since the inner lid is locked upward by the upper container, the inner lid can be automatically removed from the opening of the lower container while lifting the inner lid by the upper container.

  Further, when the upper container and the lower container are combined, the inner lid moves relatively upward in the inner space of the upper container as the upper container approaches the lower container, so that the discharge is performed. The male member of the mechanism can be smoothly inserted into the female member of the storage bag. After that, since the inner lid is locked downward by the upper container, the inner lid can be fitted into the opening of the lower container while pressing the inner lid with the upper container.

  The lower container or the inner lid may be formed with a fitting projection projecting in the direction of the opposed inner lid or the lower container. Further, the lower container or the inner lid may be formed with a fitting concave portion that engages with the fitting convex portion of the opposed inner lid or the lower container. According to this, the inner lid can be securely fitted to the lower container.

  The upper container may be provided with a locking portion on an inner peripheral surface of a peripheral wall, and the inner lid may be locked upward by the locking portion of the upper container. Further, the upper container is provided with an upper cylindrical portion through which the male member of the discharge mechanism can be inserted on an upper surface of a top wall, and a locking portion is provided on an inner peripheral surface of the upper cylindrical portion, The inner lid may be locked upward by the locking portion of the upper cylindrical portion. In addition, the upper container is provided with a lower cylindrical portion through which the male member of the discharge mechanism can be inserted on the lower surface of the top wall, and a locking portion is provided on an outer peripheral surface of the lower cylindrical portion, The inner lid may be locked upward by the locking portion of the lower tubular portion. According to this, the inner lid can be securely locked to the upper container.

  Further, the present invention is a fluid discharge container for storing a storage bag for storing a fluid and discharging the fluid in the storage bag to the outside, wherein an opening is formed and a through hole is provided from the opening. A lower container in which the storage bag having the female member provided on the upper side is stored, and a discharge mechanism having a male member inserted into the through hole of the storage bag is provided so as to be separable in the lower container. And an inner lid fitted into the opening of the lower container, and the inner lid is provided integrally with the upper container so as to be movable in an inner space of the upper container. It is characterized by the following.

  According to the present invention, when the upper container and the lower container are separated, the inner lid moves relatively downward in the inner space of the upper container as the upper container separates from the lower container. Accordingly, the male member of the ejection mechanism can be smoothly pulled out from the female member of the storage bag while holding the storage bag with the inner lid, in order to maintain the state in which the inner lid is fitted into the opening of the lower container. After that, since the inner lid is locked upward by the upper container, it can be removed from the opening of the lower container while lifting the inner lid by the upper container.

  In addition, when the upper container and the lower container are combined, as the upper container comes closer to the lower container, the inner lid relatively moves upward in the inner space of the upper container, thereby discharging the upper container. The male member of the mechanism can be smoothly inserted into the female member of the storage bag. After that, since the inner lid is locked downward by the upper container, the inner lid can be fitted into the opening of the lower container while pressing the inner lid with the upper container.

  Therefore, when replacing the storage bag stored in the container, the general consumer separates the upper container and the lower container, takes out the empty storage bag from the lower container, and then newly replaces the storage container. The simple operation of storing a suitable storage bag and connecting the upper container and the lower container makes it possible to reliably replace the storage bag in the container.

  Moreover, since it is not always necessary to provide an opening for accommodating the accommodation bag on the side surface of the lower container, it is possible to improve the degree of freedom in the design of the container.

<First embodiment>
Next, a first embodiment of a fluid discharge container (hereinafter, referred to as the present container 1) according to the present invention will be described with reference to FIGS.

  As shown in FIGS. 1 and 2, the container 1 includes a storage bag 2 for storing a fluid such as shampoo, rinse, and cosmetic liquid, a lower container 3 in which the storage bag 2 is stored, and a lower container 3. An upper container 4 provided detachably, a discharge mechanism 5 provided in the upper container 4, and an inner lid 6 fitted to the lower container 3 are provided.

  The storage bag 2 is a flexible bag made of a synthetic resin material generally called a pouch. The storage bag 2 has a female member 21 formed of a rigid resin or the like at the upper end, and a through hole 22 extending in the vertical direction is formed in the female member 21. By inserting a male member 51 of the ejection mechanism 5 described later into the through-hole 22 of the female member 21 in a close contact state, the fluid stored in the storage bag 2 is discharged from the storage bag 2 without contacting the outside air. A mechanism 5 can be connected.

  The lower container 3 has a cylindrical peripheral wall 31 that covers the side surface of the storage bag 2 and a disk-shaped bottom wall 32 that supports the bottom surface of the storage bag 2, and an opening 33 is formed at an upper portion. The storage bag 2 is stored in the lower container 3 by inserting the storage bag 2 from the opening 33.

  Further, the lower container 3 has a male screw portion 34 formed on an upper portion of an outer peripheral surface 31 a of the peripheral wall 31. The connecting male screw portion 34 is screwed with a female screw portion 43 of the upper container 4 described later.

  The lower container 3 has a fitting recess 35 formed at the upper end of the inner peripheral surface 31 b of the peripheral wall 31. When the inner lid 6 is completely fitted into the opening 33 of the lower container 3, the fitting concave portion 35 is engaged with a fitting convex portion 63 of the inner lid 6, which will be described later. 3 is formed so as to extend along the circumferential direction.

  The upper container 4 has a cylindrical peripheral wall 41 that covers the upper part of the side surface of the storage bag 2, and a disk-shaped top wall 42 that covers the upper surface of the storage bag 2. An inner space S open to the outside is formed.

  The upper container 4 has a female screw portion 43 formed below the inner peripheral surface 41a of the peripheral wall 41, and the female screw portion 43 of the upper container 4 and the male screw portion 34 of the lower container 3 are screwed together. Thereby, the upper container 4 and the lower container 3 are connected.

  Further, the upper container 4 is provided with a locking portion 44 for locking the inner lid 6 upward above the female screw portion 43 for coupling on the inner peripheral surface 41 a of the peripheral wall 41. Specifically, the inner peripheral surface 41a on which the female screw portion 43 is provided protrudes radially inward from the upper inner peripheral surface 41a, and the locking portion 44 serves as an inner peripheral surface on which the female screw portion 43 is provided. It is constituted by a step formed at the boundary between the surface 41a and the upper inner peripheral surface 41a.

  The upper container 4 is provided with a cylindrical upper cylindrical portion 45 on the upper surface of the top wall 42. The upper cylindrical portion 45 is connected to the discharge mechanism 5 with a screw or the like, and the male member 51 of the discharge mechanism 5 is inserted therethrough.

  The discharge mechanism 5 employs a so-called push-type pump dispenser, and includes a tubular male member 51 having a suction port 51a at a lower end, a pump section 52 for sucking fluid, and a discharge port 53 for discharging fluid. By pressing down the pump part 52 once or a plurality of times by hand, the fluid stored in the storage bag 2 is sucked through the male member 51 and discharged from the discharge port 53 to the outside of the container.

  The inner lid 6 is fitted to the inner edge of the opening 33 of the lower container 3, and has a circular top plate 61 covering the upper part of the storage bag 2, and a peripheral end of the top plate 61. And a side plate 62 erected from a position slightly inside the portion 61a, and is provided integrally with the upper container 4 so as to be vertically movable in the inner space S of the upper container.

  The top plate 61 is provided with a through hole 61b at the center, and the male member 51 of the ejection mechanism 5 is inserted into the through hole 61b. Further, the top plate 61 is disposed in the inner space S in such a manner that the peripheral end portion 61a can slide above the inner peripheral surface 41a of the upper container 4. For this reason, the top plate 61 can move up and down in the inner space S while maintaining a horizontal state, and when it moves upward, the upper surface is locked to the lower surface of the top wall 42 of the upper container 4. On the other hand, when it moves downward, the lower surface is locked by the locking portion 44 of the upper container 4.

  The side plate 62 is divided into two parts so as to face each other in the radial direction of the inner lid 6, and is formed in a shape along the inner peripheral surface 31 b of the lower container 3. For this reason, when the inner lid 6 is completely fitted to the lower container 3, the outer peripheral surface 62 a of the side plate 62 abuts on the inner peripheral surface 31 b of the lower container 3 in close contact.

  The side plate 62 is provided at a position slightly inside the peripheral end portion 61 a of the top plate 61. Therefore, when the inner lid 6 is completely fitted to the lower container 3, the lower surface of the peripheral end 61 a of the top plate 61 is locked to the upper end of the lower container 3.

  In the side plate 62, a fitting projection 63 that fits with the fitting recess 35 of the lower container 3 is formed along the circumferential direction on the outer surface 62a at the lower end. Therefore, when the inner lid 6 is completely fitted to the lower container 3, the fitting projection 63 is engaged with the fitting concave portion 35 of the lower container 3, so that the inner lid 6 will be described later. The state in which the lower container 3 is fitted to the opening 33 is maintained until pushed up by the upper container 4.

  Next, a method of replacing the storage bag 2 in the container 1 will be described with reference to FIGS.
