Description

  The present invention relates to a liquid applicator. More specifically, a container that contains a liquid, a hollow body that accommodates the container, an operation unit provided on the outer surface of the hollow body, and an application that communicates with the hollow body and applies the liquid to a human body or the like. The liquid applicator is provided with a portion and a liquid outflow mechanism that breaks the container and causes the liquid to flow out of the container when the operation unit is pushed toward the inside of the hollow body.

  Conventionally, as the liquid applicator as described above, for example, the one described in Patent Document 1 is known. This applicator is provided with at least one ampoule inside, but since the ampoule is made of glass, fragments are always generated when the ampoule is broken and liquid is applied. Safety measures have to be taken so that the glass pieces do not touch the object to be applied such as a human body, and the structure of the applicator is complicated. Moreover, in order to destroy glass, it had to be pressed forcefully, and the improvement of workability | operativity was also desired.

  On the other hand, paragraph 0013 of the document states that “other ampoules may include a destructible plastic, foil, or plastic thin film bag”. However, the breaking mechanism disclosed in the document is intended for glass ampules, and even when applied to ampules other than glass as described above, the ampules can not be smoothly broken and liquid can flow out, Workability will be reduced.

Special table 2010-524517

  In view of such a conventional situation, an object of the present invention is to provide a liquid applicator that can be applied by causing a liquid to flow out quickly while having a simple structure.

  In order to achieve the above object, the liquid applicator according to the present invention is characterized by a container containing a liquid therein, a hollow body that accommodates the container, an operation unit provided on an outer surface of the hollow body, and the hollow An application unit that communicates with the body and applies the liquid to a human body and the like, and a liquid outflow mechanism that breaks the container and causes the liquid to flow out of the container when the operation unit is pressed toward the inside of the hollow body The container is a bag-like object having a filling part filled with the liquid and a seal part that seals a mouth part of the filling part, and the liquid outflow mechanism is formed of the hollow body. A holding portion having a plate-like member that is located inside and outside the bag-like object and sandwiches the seal portion in a state where tension is applied to the seal portion, and the seal portion is abutted by pressing the operation portion. A contact portion that contacts, The holding portion is formed with a gap allowing the lowering of the abutting portion, and the abutting portion is brought into contact with the seal portion within the gap by pressing the operating portion toward the inside of the hollow body. A cut is formed to allow the liquid to flow out of the filling portion.

  According to the above configuration, the container is a bag-like object having a filling part filled with a liquid and a seal part sealing the mouth of the filling part, and the liquid outflow mechanism is inside the hollow body and outside the bag-like object. And a holding portion having a plate-like member that holds the seal portion in a state where tension is applied to the seal portion, and a contact portion that contacts the seal portion. The holding portion is formed with a gap that allows the contact portion to descend. As a result, tension is applied to the seal portion located in the gap portion, so that even if the operation portion is pressed with a small force, a cut can be formed in the seal portion by the lowered contact portion. Moreover, since the seal portion is tensioned, the filling portion is opened by tearing the seal portion with the formed cut as a starting point, and the liquid can flow out quickly. Moreover, the container is a bag and the liquid outflow mechanism only forms a cut. Therefore, since no fragments of the container are generated inside the hollow body, it is clean and highly safe, no special safety measures are required, and the structure is simple.

  The abutting portion is a long member along the axial direction of the hollow body, and the lower end portion of the abutting portion is substantially V in the axial direction so that the width is larger than the width of the gap. It is good to form in the shape of a letter. Since the lower end is substantially V-shaped, a cut can be formed even with a smaller force. In addition, since the substantially V shape is formed so as to be larger than the width of the gap, pressing the operation part toward the inside of the hollow body causes the contact part to tear the seal part, which makes it smoother. The filling part can be opened.

  In such a case, it is preferable that a space is formed inside the contact portion along the axial direction. As a result, even if the abutting portion descends and passes through the gap portion, most of the liquid flowing out from the filling portion flows through the inner space of the abutting portion and flows, so that the outflow of liquid is inhibited by the abutting portion itself. The liquid can be circulated more smoothly.

  The seal portion has a pair of first through holes, the plate-like member has a pair of protrusions that penetrate the first through holes, and the pair of first through holes and the pair of protrusions are: It is good to arrange | position facing the said gap | interval. This prevents the seal portion from shifting (moving or sagging) in the gap portion, and tension can be applied to the seal portion in the gap.

  In this case, the plate-like member includes a first plate-like member on which the ridge is formed and a second plate-like member having a second through-hole that penetrates the ridge, and the seal portion is formed on the first plate. It is good to pinch with a plate-shaped member and said 2nd plate-shaped member. As a result, it is possible to prevent the seal portion from being displaced more firmly and to apply tension to the seal portion in the gap.

  The first plate-like member may further include a protruding portion that protrudes upward between the protrusion and the gap. Since the central portion of the seal portion sandwiched between the first plate-like member and the second plate-like member is raised by the protruding portion, further tension is applied to the portion, and the seal portion can be torn quickly and easily.

  The operation part has a handle part extending along the axial direction from a base end part provided on an outer surface of the hollow body, and only one end of the handle part is fixed to the hollow body, The first through hole, the second through hole, and the protrusion may be disposed on the other end side of the handle portion from directly below or directly below the base end portion. The downward pressing force generated by the operation of the handle portion is easily applied to the other end side of the handle portion which is the proximal end portion of the operation portion or the free end behind the operation portion. Therefore, by providing a pair of first through holes, second through holes and protrusions at positions where the load is easily applied, the seal portion is prevented from being displaced or slackened due to the load (pressing force). The tension of the part can be maintained.

  The holding portion has a leg portion that protrudes toward the hollow body and forms the gap, and the hollow body has a locking portion that locks the leg portion on an inner surface thereof, and the locking portion is The holding unit may be positioned directly below the operation unit. Thereby, position shift with respect to the operation part of a holding | maintenance part can be prevented, and a seal | sticker part can be tensioned and hold | maintained. In addition, the pressing force of the operation unit can be more efficiently used to form the cut by positioning the holding unit directly below the operation unit.

  The seal portion may include an easy opening processing portion formed along the axial direction of the cut. Thereby, a cut can be formed with a smaller force. In such a case, the easy-open processing portion may be a perforation formed along the gap.

  According to the characteristics of the liquid applicator according to the present invention, it is possible to apply the liquid quickly by flowing out while having a simple structure.

Next, the present invention will be described in more detail with reference to FIGS.
As shown in FIGS. 1 to 3, the liquid applicator 1 according to the present invention is generally provided on a container 2 that contains a liquid L, a hollow body 3 that houses the container 2, and an outer surface 31 of the hollow body 3. The operation unit 4, the application unit 5 that communicates with the hollow body 3 and applies the liquid L to the human body, and the operation unit 4 is pushed toward the inside of the hollow body 3, thereby destroying the container 2 and the liquid L And a liquid outflow mechanism 10 for allowing the liquid to flow out of the container 2.

  As shown in FIGS. 2 and 7, the container 2 is a bag-like object 20 in which, for example, a synthetic resin film is bonded and the periphery thereof is sealed by heat welding or the like. The bag-like object 20 has a substantially rectangular shape along the axial direction X of the hollow body 3, and has a filling portion 21 filled with the liquid L and a seal portion 23 that seals the mouth portion 22 of the filling portion 21. A perforation 24 is formed in the middle of the seal portion 23 along the axial direction X of the hollow body 3. In the present embodiment, the perforation 24 functions as an easy-open processing unit. In addition, a pair of first through holes 25 and 25 are formed in the seal portion 23 with the perforation 24 interposed therebetween, and a pair of protrusions 64 and 64 of the holding portion 6 described later pass therethrough.

  In the present invention, the liquid L filled in the bag 20 is not particularly limited, and is, for example, a disinfectant solution or a chemical solution applied to the patient's skin before surgery. Moreover, the material of the film of the bag-like object 20 can be appropriately selected according to the physical properties of the liquid L to be filled, sterilization treatment, and the like, and is not particularly limited.

  As shown in FIGS. 1 to 3, the hollow body 3 is formed into a flat shape by press molding or the like, for example, and a housing space 30 for housing the container 2 is formed therein. On the outer surface 31 of the hollow body 3, a later-described operation unit 4 is integrally formed. Further, as shown in FIG. 6, a stepped portion 33 a and a protruding portion 33 b are formed on the inner surface 32 along an orthogonal direction Y orthogonal to the axial direction X. As shown in FIG. 3, the stepped portion 33 a and the protruding portion 33 b are formed at substantially symmetrical positions with respect to a base end portion 41 described later. In the present embodiment, the stepped portion 33 a and the protruding portion 33 b constitute the locking portion 33. The opening 34 is provided with a coating portion 5 to be described later, and the rear end portion 35 is formed with a vent hole 36 for releasing the air in the accommodation space 30 to the outside.

  As shown in FIGS. 1 to 5, the operation portion 4 is substantially in a plan view extending from the base end portion 41 along the axial direction X and a base end portion 41 standing from the outer surface 31 of the hollow body 3. A plate-like handle portion 42 is provided. The front end portion 42 a of the handle portion 42 is fixed to the hollow body 3 through the opening 34, but the rear end portion 42 b is not fixed to the hollow body 3. Accordingly, when the rear end portion 42 b is pressed toward the hollow body 3, the base end portion 41 deforms the hollow body 3 and lowers the contact portion 7. Although illustration is omitted, it is also possible to provide a latching part for latching the rear end part 42b pressed against the outer surface 31 of the hollow body 3. However, in such a case, the fluidity of the liquid L decreases because the contact portion 7 is held at a position near the seal portion 23 even after the cut is formed in the bag-like object 20.

  As shown in FIGS. 1 to 3, the application unit 5 includes a sponge 51 that applies the liquid L to a human body and the like, and a circulation passage 52 that connects the sponge 51 and the accommodation space 30 and distributes the liquid L. The sponge 51 is made of a porous material such as felt or an open cell material, and is fixed to the pedestal 53 by adhesion or the like. Further, the circulation passage 52 communicates with the sponge 51 through a hole 54 formed in the central portion of the pedestal 53. In the present invention, the material, structure, shape, size, number, position, and the like of the sponge 51, the flow passage 52, the pedestal 53, and the hole 54 are appropriately determined according to the physical properties of the liquid L to be filled, the outflow amount of the liquid, and the like. What is necessary is just to select and it does not specifically limit. Although not shown, one or a plurality of slits may be formed on the surface of the sponge 51, and the shape, size, number, position, etc. may be selected as appropriate.

  As shown in FIGS. 2 and 5, the liquid outflow mechanism 10 includes a holding part 6 that holds the seal part 23 of the bag-like object 20 and a contact part 7 that comes into contact with the seal part 23 when the operation part 4 is pressed. . In the present embodiment, the holding portion 6 and the contact portion 7 are separate from the hollow body 3 and are built in the storage space 30.

  As shown in FIGS. 5 and 7, the holding portion 6 includes first and second plate-like members 61 and 62 that sandwich the seal portion 23. In the first and second plate-like members 61, 62, a gap 63 that allows the abutting portion 7 to be lowered, which will be described later, is formed along the axial direction X and positioned at the center in the orthogonal direction Y. In the first plate-like member 61, a pair of protrusions 64, 64 penetrating the pair of first through holes 25, 25 of the seal portion 23 are arranged to face each other with a gap 63 interposed therebetween. As a result, tension is applied to the seal portion 23 on the gap 63. Further, the first plate-like member 61 is formed with a leg portion 65 that protrudes toward the hollow body 3 and forms a gap 63. As shown in FIG. 6, the bottom portion 65 a of the leg portion 65 is engaged with the stepped portion 33 a and the protruding portion 33 b of the hollow body 3, so that the seal portion 23 is positioned with respect to the base end portion 41, and the axial direction X Prevents misalignment.

  The second plate member 62 is formed with a second through hole 66 through which the protrusion 64 passes. The end portion 62a has a bent portion 67 bent downward, and the tip thereof has a protruding portion 67a protruding toward the gap 63 side. Accordingly, the end portions 61a and 62a are fitted to prevent the film constituting the seal portion 23 from being displaced and sag, and reliably hold it. Further, support portions 68 for positioning the contact portion 7 above the gap 63 are formed at the four corners of the second plate-like member 62.

  As shown in FIGS. 5, 7, and 8, the contact portion 7 is formed in a long shape along the axial direction X of the hollow body 3, and the lower end portion 71 has a width W <b> 1 larger than a width W <b> 2 of the gap 63. Thus, it is formed in a substantially V shape when viewed in the axial direction. Moreover, the front-end | tip 72 of the lower end part 71 is formed in the shape of a saw blade. A space 73 is formed along the axial direction X inside the contact portion 7.

  Here, as shown in FIG. 3, the base end portion 41 of the operation portion 4 is formed along the axial direction X, and the central portion of the base end portion 41 in the axial direction X is wide along the orthogonal direction Y. Is formed. Therefore, when the handle portion 42 is pressed, the weight is sequentially applied from the base end portion 41 on the rear end 42b side. Further, since the distal end portion 42 a of the handle portion 42 is fixed to the opening portion 34, the pressing force at the base end portion 41 is slightly applied to the opening portion 34. Therefore, the first through hole 25 of the seal portion 23, the second through hole 66 of the second plate member 62, and the protrusion 64 of the first plate member 61 are the central portion of the base end portion 41 in the axial direction X or the It is arranged on the rear end portion 42b side of the handle portion 42 from directly below. By positioning the first through-hole 25, the second through-hole 66, and the protrusion 64 for holding the seal portion 23 at a position where the load is easily applied, the displacement and sagging of the seal portion 23 generated during pressing are strongly strengthened. Therefore, the tension of the seal portion 23 can be maintained. Also, the pressing force can be used efficiently.

Next, the operation of the liquid outflow mechanism 10 will be described with reference to FIG.
When the handle portion 42 of the operation portion 4 is pressed, the hollow body 3 is deformed by the pressing force, and the contact portion 7 is lowered. As shown in FIG. It abuts on the seal portion 23 located above. When the cut C is formed in the seal portion 23 and the contact portion 7 is further lowered, the seal portion 23 held by the holding portion 6 is pulled outward as shown in FIG. Therefore, the film (seal part 23) is torn from the formed cut C, the mouth part 22 is cut, and the liquid L flows out from the filling part 21. When the abutting portion 7 is further lowered, the width W1 of the lower end portion 71 is larger than the width W2 of the gap 63, so that the lower end portion 71 spreads the gap 63 as shown in FIG. ) Is torn further. In addition, since most of the liquid L that has flowed out passes through the space 73 of the contact part 7, it is possible to prevent the liquid L from flowing out of the contact part 7, and the liquid L from the filling part 21 flows smoothly.

Finally, other embodiments of the present invention will be mentioned with reference to FIGS. In addition, the same code | symbol is attached | subjected to the member similar to the above-mentioned embodiment.
In the above embodiment, the lower end 71 is tapered so that the width W1 is larger than the width W2 of the gap 63. However, for example, as shown in FIG. 9A, the width W <b> 1 of the contact portion 7 ′ can be formed to be smaller than the width W <b> 2 of the gap 63. However, the above embodiment is superior in that the seal part 23 is cut quickly. In addition, as shown to the figure, you may provide a pair of auxiliary leg part 69 and 69 symmetrically to the leg part 65 which forms the gap | interval 63, and may improve the stability of the holding | maintenance part 6. FIG.

  In the above embodiment, the pair of protrusions 64 and 64 of the first plate-like member 61 are configured to penetrate through the first through holes 25 and 25 of the seal portion 23. However, for example, as shown in FIG. 9B, the pair of protrusions 64 and 64 are omitted, and the seal portion 23 is sandwiched between the first and second plate-like members 61 ′ and 62 ′ and bonded by bonding or the like. It may be fixed. It suffices if the seal portion 23 (film) does not cause any positional deviation or sagging relative to the holding portion 6.

  In the above embodiment, the contact portion 7 is supported by the support portion 68 of the second plate-like member 62. For example, as shown in FIG. 7 ″ may be provided separately from the holding portion 6. Note that the abutting portions 7 ′ and 7 ″ as shown in FIGS. 9A and 9C do not have the internal space 73. . In particular, the abutting portion 7 ″ of FIG. 9C is wide. Therefore, in these embodiments, the liquid L flowing out from the filling portion 21 of the bag-like object 20 avoids the abutting portions 7 ′ and 7 ″. Then, it flows into the gap 63. Therefore, the above-described embodiment is superior in terms of quick outflow.

  The dimensions and shapes of the hollow body 3 and the operation unit 4 are not limited to the above-described embodiment, and for example, an aspect as shown in FIG. 10 is possible. As illustrated in the figure, the hollow body 3 ′ is formed in a substantially square shape in a sectional view, and the vicinity of the base end portion 41 of the operation portion 4 ′ is wider than the rear end portion 35 side in a plan view. Good. Further, the front end portion 42a 'of the operation portion 4' may be formed substantially linearly from the rear end portion 42b without being curved. Thereby, the pressing force generated at the rear end portion 42b can be efficiently transmitted to the base end portion 41, and the bag-like object 20 can be smoothly cut.

  Further, as shown in FIG. 11, a protruding portion 61 b that protrudes upward may be provided at the intersection of the first plate-like member 61 and the leg portion 65. Accordingly, it is possible to further apply tension to the vicinity of the perforation 24 at the center of the belt-like seal portion 23 of the bag-like object 20, and it is possible to form a cut more easily. The protrusion 61b is preferably provided between the protrusion 64 and the gap 63 of the first plate-like member 61. A mode in which the perforation 24 can be easily and quickly cut by applying tension to the seal portion 23. If it is, the shape and the number are not particularly limited.

  In the above embodiment, the locking portion 33 is configured by the step portion 33 a and the protruding portion 33 b formed on the inner surface 32 of the hollow body 3. However, the configuration of the locking portion is not limited to this as long as it can prevent the displacement of the holding portion 6 with respect to the operation portion 4.

  In the embodiment, the perforation 24 is formed in the seal portion 23 along the axial direction X. However, the easy-open processing portion is not limited to the perforation, and the film may be weakened by, for example, applying fine holes, embossing, or scratches to the seal portion 23. In such a case, it is preferable to process the hollow body 3 so as to be easily cut along the axial direction X. These weakening processes and perforations (zippers) can also be implemented in combination.
