JP4916990B2 - Liquid ejection container - Google Patents

Description

  The present invention relates to a liquid ejection container including an intermediate dish that rises while pushing up contents by using a negative pressure generated in a filling space in a container body.

Focusing on the fact that the remaining amount of contents cannot be confirmed when the barrel of the container body is made opaque in a conventional liquid ejection container, so that a spherical solid can be attached to and detached from the back of the middle dish placed above the bottom of the container It has been proposed to allow this solid to fall to the bottom of the container body at the timing when the inner plate reaches the top dead center, thereby enabling an audible remaining amount confirmation by a falling sound or the like (for example, a patent) Reference 1).
JP 2002-320886 A

  However, depending on the user's preference, there is a tendency that after the user confirms the remaining amount with a warning sound, a second warning sound is unnecessary, and such demand is especially intended for carrying a container. It is thought that it is big.

  In addition, the conventional container has room for improvement in terms of effective use of the remaining liquid because the reduction of the filling space for the contents depends only on the rise of the intermediate dish.

  The problem to be solved by the present invention is that after the user confirms the remaining amount, there is still room for improvement in terms of sounding a warning and effective use of the remaining liquid. What is to be done is to provide a liquid ejection container that is quiet and convenient to carry by making a single warning sound for checking the remaining amount of contents while making effective use of the remaining liquid.

  The present invention includes a container main body having a mouth portion for filling the contents, the mouth portion being connected to the trunk portion via a shoulder portion, a pump attached to the mouth portion of the container main body, and a pump connected to the pump. The nozzle head that operates the pump by repeatedly lowering and returning and ejects the contents, and is slidably arranged inside the body of the container body, and pushes up the contents by the negative pressure generated when the contents are ejected A liquid jetting container including a middle dish that rises while the container body has an outer peripheral portion that is slidable on an inner peripheral surface of the body portion along the axis of the container body, An upper plate that is connected to the outer peripheral portion and has a cylindrical portion that disposes the pump on the inside, and that forms a filling space for the contents between the inner plate and the upper plate. The upper plate is restrained from falling down and the middle plate A detachable locking portion that gives at least one of a shocking sound and a feeling of impact and allows the upper plate to descend by releasing the hook by the negative pressure generated in the filling space after reaching the point Is provided.

  The locking portion provided on the upper plate according to the present invention can be appropriately provided at various positions according to the shape of the inner surface of the container body. It is preferable to be configured to be hooked on the peripheral surface. This is because the other space can be effectively used as a filling space for the contents by utilizing the gap between the mouth and the pump mounted on the mouth.

  In addition, for example, the engaging portion is a convex portion that rides on and fits a convex portion formed on the inner peripheral surface of the container main body, a convex portion that fits into a concave portion formed on the inner peripheral surface of the container main body, or a container A concave portion into which a convex portion formed on the inner peripheral surface of the main body is fitted is exemplified.

  In addition, according to the present invention, a see-through portion that can be seen through the inside of the container main body is formed immediately below the shoulder portion of the body portion of the container main body, and the upper plate is held by the upper plate. The decoration part from which the visual recognition state from the said fluoroscopy part changes in the state which descended from can be provided.

  In this case, the decorating part is provided on the outer peripheral surface of the outer peripheral part, and is visible from the fluoroscopic part when the upper plate is hooked, and is not visible when the upper plate is lowered. be able to.

  In the case of such a configuration, it is preferable to form a gap for providing the decorating part between the container body and the outer peripheral surface of the outer peripheral part.

  Moreover, the said decoration part is provided in the outer peripheral surface of the said cylindrical part, and when the said upper plate is hooked, it cannot be visually recognized from the said fluoroscopy part, and shall be visible when the said upper plate descend | falls. You can also

  In the case of such a configuration, it is preferable to form a gap for providing the decorating part between the outer peripheral surface of the cylindrical part and the container body. Furthermore, according to this invention, both of these decoration parts can also be provided.

  In the present invention, “decoration” refers to visually appealing characters, figures, symbols, colors, patterns, or combinations thereof. Examples of the method for decorating include printing and labeling. However, when providing a decoration part in the outer peripheral surface of the said outer peripheral part, and the outer peripheral surface of the said cylindrical part, it is preferable to make mutually different decoration.

  According to the present invention, when the middle pan that rises with the ejection of the contents reaches top dead center, the upper pan that has been hooked on the container body is released. In addition to making an impact sound (click sound), the hand holding the container is given an impact feeling (click feeling). Thereby, even if a user completes the warning sound emitted for the remaining amount confirmation of the contents once, the user can surely recognize that the contents remain little by hearing and touch.

  In addition, when the catch of the upper plate is released, the upper plate that forms a filling space together with the middle plate descends toward the middle plate that has reached the top dead center. Can be spouted.

  Therefore, according to the present invention, it is possible to provide a liquid ejection container that is quiet and convenient to carry by making a warning sound emitted for checking the remaining amount of contents at a time while effectively utilizing the remaining liquid. it can.

  In addition, in the present invention, a see-through portion that can be seen through the container main body is formed immediately below the shoulder portion of the body portion of the container main body, and the upper plate is lowered from the state where the upper plate is held. If the decoration part that changes the visual recognition state from the fluoroscopic part is provided, the visual recognition state from the fluoroscopic part of the container body changes, so that even after the catch of the locking part is released, the sense of hearing and touch Since the remaining amount can be confirmed without using any, it is more effective in providing a liquid ejection container that is quiet and convenient to carry.

  For example, according to the present invention, on the outer peripheral surface of the outer peripheral portion, a decorative portion that is visible from the see-through portion when the upper plate is caught and is not visible when the upper plate is lowered is provided. The remaining amount can be confirmed by making it impossible to visually recognize the decorative portion from the see-through portion of the container body.

  In the case of such a configuration, if a gap for providing the decorative portion is formed between the outer peripheral portion and the container body, the decorative portion does not interfere with the container main body. Good.

  Further, according to the present invention, if a decorative portion is provided on the outer peripheral surface of the tubular portion that is not visible from the see-through portion when the upper plate is caught, and is visible when the upper plate is lowered. The remaining amount can be confirmed by making the decoration part visible from the see-through part of the container body.

  In the case of such a configuration, even if a gap for providing the decorating portion is formed between the outer peripheral surface of the cylindrical portion and the container main body, the same applies.

  In particular, if both of these decorative portions are provided, the number of places that can be visually confirmed increases. Moreover, when providing a decorating part in the outer peripheral surface of the said outer peripheral part, and the outer peripheral surface of the said cylindrical part, respectively, you may make a see-through part into a single unit, or you may form each separately.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a side view showing a partial cross section of an unused state of the liquid ejection container 100 according to the first embodiment of the present invention, and FIG. 2 shows a state in which an inner plate 140 of the same form has reached top dead center. FIG. Furthermore, FIG. 3 is a side view showing the used state of the same form in a partial cross section.

  In the drawing, reference numeral 110 denotes a container main body having a cylindrical mouth portion 111 that is filled with contents, and the mouth portion 111 is integrally connected to a cylindrical body portion 113 via a shoulder portion 112.

  The container body 110 is made of a transparent or translucent synthetic resin. An opaque film F having a light shielding property is wound around the container main body 110. By partially or transparently opening a part of the film F, the shoulder portion 112 of the body portion 113 is directly below the shoulder portion 112. A see-through portion 114 made of a transparent synthetic resin is locally formed. Further, a bottom lid portion 115 having an outside air introduction hole h is separately attached to an end portion of the body portion 113 facing the mouth portion 111 along the axis O of the container body 110.

  Reference numeral 120 denotes an existing pump that is attached to the mouth portion 111 and sucks, compresses, and discharges contents by repeatedly pressing and returning.

  Specifically, the pump 120 includes a cover 121, and the cover 121 has a mounting cylinder 121a that is detachably screwed to the mouth 111 outside the mouth 111, and inside the mounting cylinder 121a. The cylinder 122 that hangs down the inside of the mouth 111 in a cylindrical shape via the top wall 121b is integrally formed.

  The cylinder 122 hangs down from the inside of the mouth portion 111, and a suction port is formed at a tip portion 120a thereof. Further, the cylinder 122 is attached to the upper end of the mouth part 111 via the seal ring S, and keeps a space between the mouth part 111 and the cylinder 122 in an airtight state.

  Reference numeral 130 denotes a nozzle head that is connected to the pump 120 and operates the pump 120 by repeatedly pressing down and returning to eject the contents.

  Reference numeral 140 denotes an intermediate dish that is slidably disposed inside the body 113 and serves as a substantial bottom of the container body 110. The inner plate 140 has an outer edge portion 141 that is slidably held inside the body portion 113, and has a bottomed cylindrical shape that extends toward the mouth portion 111 via an annular top wall portion 142 on the inner side. The part 143 is integrally formed.

  The inner bottom portion 143a of the bottomed cylindrical portion 143 comes into contact with the tip portion 120a of the cylinder 122 by the rising of the middle plate 140, and determines the top dead center of the middle plate 140. In the unused state before the contents are ejected, the inner tray 140 is seated on a cylindrical seat wall 115a that is integrally provided upright from the bottom lid portion 115, as shown in FIG.

  Reference numeral 150 is made of a synthetic resin having the same light-shielding color as the container main body 110, and is disposed on the mouth 111 side of the inner dish 140 to form a content filling space R between the inner dish 140 and the inner dish 140. It is an upper plate to do.

  The upper plate 150 has an outer peripheral portion 151 that can slide on the inner peripheral surface 113f of the body portion 113 along the axis O, and can be in close contact with the inner surface 112f of the shoulder portion 112 of the container main body 110. A cylindrical portion 153 that stands up from the inside of the mouth portion 111 via the base portion 152 is integrally formed.

  The cylindrical portion 153 is integrally formed with a seal portion 154 that is slidably held on the outer peripheral surface of the cylinder 122. Thus, a filling space R in which the airtightness between the middle plate 140 and the upper plate 150 and the pump 120 is maintained is formed inside the container body 110.

  Further, the upper plate 150 is caught by the container main body 110 to restrict the lowering of the upper plate 150, and the hook is caused by the negative pressure generated in the filling space R after the middle plate 140 reaches the top dead center. A removable locking portion 155 that is released and allows the upper plate 150 to descend is provided.

  Here, FIGS. 4 and 5 are main part cross-sectional views showing the main parts in a state before the upper plate 150 is lowered and in a used state, respectively, in the same form.

  Referring to FIGS. 4 and 5, the locking portion 155 is a convex portion that integrally protrudes outward from the tubular portion 153 as described in detail in FIG. 4.

  The locking portion 155 is formed in an annular shape or intermittently (including one or a plurality of both) along the periphery of the cylindrical portion 153, and is formed annularly or intermittently integrally with the inner peripheral surface 111f of the mouth portion 111. The upper plate 150 is held in a state of being caught on the container main body 110 by riding on and fitting the convex portion 111a (including both of the single or plural).

  Thereby, the upper plate 150 does not move toward the middle plate 140 until a predetermined negative pressure is generated in the filling space R and a predetermined force is applied, as shown in FIG.

  That is, the locking portion 155 rises due to the negative pressure generated in the filling space R by the inner tray 140, and until the inner tray 140 reaches the top dead center, as shown in FIG. The hook is not released, but after the inner plate 140 reaches the top dead center, if further negative pressure is generated in the filling space R by ejecting the contents, the negative pressure causes As shown in FIG. 5, the catch is released.

  According to the present invention, when the intermediate tray 150 that rises as the contents are ejected from the state shown in FIG. 1 reaches the top dead center as shown in FIG. Since the hook of the upper plate 150 that has been hooked is released, a click sound is generated at the moment of the release, and a click feeling is given to the hand holding the container 100. Thereby, even if a user completes the warning sound emitted for the remaining amount confirmation of the contents once, the user can surely recognize that the contents remain little by hearing and touch.

  Moreover, when the catch of the upper plate 150 is released, the upper plate 150 that forms the filling space R together with the inner plate 140 has reached the top dead center due to the negative pressure in the filling space R as shown in FIG. Since it descends toward the inner plate 140, it is possible to take out the remaining liquid that could not be used conventionally and to eject it to the outside.

  Therefore, according to the present invention, it is possible to provide a liquid ejection container that is quiet and convenient to carry by making a warning sound emitted for checking the remaining amount of contents at a time while effectively utilizing the remaining liquid. it can.

  The setting of the timing for releasing the hook between the locking portion 155 and the convex portion 111a is, for example, the amount of hooking with the convex portion 111a formed in the mouth portion 111, the locking portion 155 or the convex portion 111a. The shape or the hardness thereof can be changed as appropriate.

  Further, the engaging portion 155 is not only a convex portion that rides on the convex portion 111a and fits, but the convex portion 111a is replaced with a concave portion, and the convex portion that fits into the concave portion, or the convex portion is replaced with the convex portion. Examples include a recess into which 111a is fitted. In addition, in order to realize smooth sliding of the upper plate 150, the outside air introduction hole h is formed in the shoulder portion 112 in the same manner as the bottom lid portion 115.

  In addition, in this embodiment, a decorative portion that is visible from the fluoroscopic portion 114 when the upper plate 150 is caught on the outer peripheral surface of the outer peripheral portion 151 of the upper plate 150 and is not visible when the upper plate 150 is lowered.

  Specifically, an annular recess 151a that circulates along the outer peripheral portion 151 is formed in the outer peripheral portion 151 of the upper plate 150, and a decoration portion D1 is provided in the annular recess 151a. As a result, the two annular outer peripheral edges 151b divided vertically by the annular recess 151a are each slidably held by the body inner peripheral surface 113f, and the decoration part D1 is the body inner peripheral surface. No interference with 113f.

  According to this configuration, the size of the see-through part 114 and the decoration part D1, the bottom dead center when the upper dish 150 is lowered, that is, the bottomed cylindrical part 143 of the middle dish 140 at the top dead center is added to the upper dish. By appropriately setting the position where the base portion 153 of the 150 contacts, the decorative portion D1 is visible from the fluoroscopic portion 114 when the upper plate 150 is hooked, and is not visible when the upper plate 150 is lowered. It becomes possible.

  That is, since it becomes impossible to visually recognize the decorative portion D1 from the see-through portion 114 of the container body 110, the remaining amount can be reduced without using any sense of hearing or touch after the catch of the locking portion 155 is released. Since it can be confirmed, it is more effective in providing a liquid ejection container that is quiet and convenient to carry.

  Similarly, in this embodiment, the decorative portion that is not visible from the fluoroscopic portion 114 when the upper plate 150 is caught on the outer peripheral surface 153f of the upper plate cylindrical portion 153, and is visible when the upper plate 150 is lowered. D2 is provided.

  Specifically, a decorative portion D2 is provided from the upper plate locking portion 155 to the end of the cylindrical portion 153. As a result, the decorative portion D2 is interposed in the gap between the outer peripheral surface 153f of the upper dish cylindrical portion and the inner peripheral surface 111f of the mouth, and therefore does not interfere with the inner peripheral surface 111f of the mouth.

  According to this configuration, as in the case of the decoration part D1, the decoration part D2 can be set by appropriately setting the size of the see-through part 114 and the decoration part D2, the bottom dead center when the upper plate 150 is lowered, and the like. Is not visible from the fluoroscopic part 114 when the upper plate 150 is caught, and can be viewed when the upper plate 150 is lowered.

  That is, since the decoration part D2 can be visually recognized from the see-through part 114 of the container body 110, as with the decoration part D1, after the catch of the locking part 115 is released, any sense of hearing or touch is used. Therefore, the remaining amount can be confirmed, which is more effective in providing a liquid ejection container that is quiet and convenient to carry.

  In the present invention, when the decoration portions D1 and D2 are provided on the outer peripheral portion 151 and the cylindrical portion 153 of the upper plate 150, respectively, it is preferable that the decorations are different from each other. For example, when the decoration part D1 is pink, the decoration part D2 is yellow.

  FIG. 6 is a side view showing a partially sectioned state of a liquid ejection container 200 according to another embodiment of the present invention, and FIGS. 7 and 8 are respectively the same configuration before the upper plate 150 is lowered. It is principal part sectional drawing which shows the principal part of this state and a used state in a cross section.

  The basic configuration of the present embodiment is the same as that of the first embodiment, but the seal portion 154 of the upper plate 150 is configured by expanding the end of the tubular portion 153 so that the decorating portion D2 is It is provided between the seal part 154 and the locking part 155. As a result, the decorative portion D2 is interposed in the gap formed between the mouth inner peripheral surface 111f and does not interfere with the mouth inner peripheral surface 111f as in the first embodiment.

  Therefore, the same form can also obtain the same operation effect as the first form. In addition, the cylindrical portion 153 according to this embodiment forms a filling space R between itself and the inner tray 150 by being slidably held by the pump 120 on the outer side, but how to provide the seal portion 154 As described above, as in the first embodiment, the filling space can be slidably held by the pump 120 inside or slidably held by the pump 120 at the inside. R may be formed.
