Summary of the Invention

Problems to be Solved by the Invention

[0007] On the other hand, conventional dispensing methods often impose limitations on the container itself, such as the presence or absence of a pump mechanism or whether the container can be pushed in, resulting in a lack of versatility.

[0008] Furthermore, conventional inverted containers were often designed to hold contents with relatively high viscosity, such as glue or toothpaste, and therefore had limitations on the types of contents they could hold due to issues like leakage when inverted and running out of liquid during use.

[0009] The present invention has been made in view of the above, and aims to solve the problem of providing a highly convenient dispenser and a container equipped with such a dispenser. [Means for solving the problem]

[10] The first connecting body is provided with a contact portion that contacts the second connecting body with a predetermined width, and the outer diameter of the contact portion is formed to be the same as the outer diameter of the second connecting body. The discharge device according to [9].

[0021]

[10] .

[0022]

[12] The connecting portion includes a liquid flow operation portion that operates the flow direction or flow rate of the content. The discharge device according to any one of [1] to

[0032]

[22] A container including a discharge port for discharging the content, wherein the discharger according to any one of [1] to

[21] is provided at the discharge port.

[0033]

[23] A container having a discharge port for discharging contents, wherein the discharge port has a liquid flow control section for controlling the direction or flow rate of the contents, and a discharger according to any one of [1] to

[21] is provided at the discharge port.

[0034] [1] Dispensers like the one shown are attached to a container and expand and contract the air intake space of the dispensing section, thereby supplying outside air to the internal space of the container which is airtightly connected to the air intake space, and the air supplied into the internal space of the container pushes out the contents of the container. Therefore, the user of the dispenser can easily dispense the contents of the container by expanding or contracting the air intake space of the dispenser attached to the container.

[0035] Dispensers like the one in [2] allow for easy expansion and contraction of the air intake space at the dispensing section by pressing the opening against any surface, such as a wall or the palm of a hand. This makes it easier for the user of the dispenser to dispense the contents of the container. Furthermore, the enlarged diameter section and opening can suppress the scattering of contents when they are discharged.

[0036] Dispensers like the one in [3] allow for easy expansion and contraction of the air intake space at the dispensing section by pressing the opening against any surface, such as a wall or the palm of a hand. This makes it easier for the user of the dispenser to dispense the contents of the container.

[0037] Dischargers like [4] and [5] have discharge sections that can easily be restored to their original shape after being deformed when the air supply space expands or contracts. Therefore, users of the discharger can easily reuse the discharger.

[0038] Dispensers like [6] and [7] allow for easy expansion and contraction of the air supply space at the dispensing section by pressing the opening edge against any surface such as a wall or the palm of a hand. This makes it easier for the user of the dispensing device to dispense the contents of the container.

[0039] In a discharger like the one in [8], the main body of the connector can help to make a firm and airtight connection between the discharger and the outlet of the container.

[0040] [9] Dispensers like the one shown can be modified by altering the first or second connector, allowing the same shape of dispensing section to be attached to various containers.

[0041] Dischargers like the one in

[10] have a large contact area between the first and second connectors that are connected to each other, which allows for stable expansion and contraction of the air supply space (deformation of the discharge section by pressing) and maintains the aesthetic appearance of the container.

[0042] Dischargers like the one in

[11] have an auxiliary discharge port that limits the expansion and contraction of the air supply space, allowing the amount of liquid discharged each time to be adjusted to a certain range. Furthermore, the protruding portion of the auxiliary discharge port can impart effects to the dispenser depending on its shape. For example, making the protruding portion trumpet-shaped can improve liquid flow.

[0043] Dischargers like the one in

[12] can restrict the direction and amount of liquid flow by liquid flow control parts such as check valves and stoppers. In other words, liquid flow control parts can prevent situations such as unexpected discharge of the contents.

[0044] Dispensers like the one in

[13] have multiple stages of liquid flow control parts such as check valves and stoppers, which allows the discharge volume to be adjusted within a certain range and further suppresses the occurrence of unexpected discharge of contents.

[0045] In a dispenser like the one shown in

[14] , the connecting tube can guide the contents of the container to the outlet to which the connecting body is attached. This allows the user of the dispenser to dispense the contents of the container regardless of the orientation of the container.

[0046] In a dispenser like the one described in

[15] , the weight at the tip of the connecting tube can assist in inserting the connecting tube into the contents of the container even if the orientation of the container changes. Therefore, the user of the dispenser can dispense the contents of the container regardless of the orientation of the container.

[0047] In a discharger like the one described in

[16] , the ridge of the connection part suppresses deformation of the connection part due to operations that expand or contract the air supply space, and makes the connection with the container outlet, etc., stronger and more airtight.

[0048] In a dispenser like the one in

[17] , when the lid of a container is attached, the closing part closes the path from the discharge port to the air supply space, thereby suppressing leakage of the contents of the container.

[0049] In a dispenser like the one described in

[18] , when a lid is attached to a container or the like, the closing part and the closing auxiliary part work together to close the path from the discharge port to the air supply space. That is, the closing auxiliary part can enhance the effect of suppressing leakage of the contents of the container. Furthermore, the closing assist unit can suppress leakage of the contents of a container by suppressing the expansion and contraction of the air supply space when attaching the lid of a container.

[0050] In a dispenser like the one described in

[19] , the fixing part stabilizes the position of the lid when the lid of a container is attached, thereby suppressing leakage of the contents of the container and tipping over. Furthermore, since the lid is fixed to the installation location, the user can lift the container or other object placed on it using the lid as a base, without having to hold the lid down with their hand.

[0051] In a dispenser like the one shown in

[20] , the cylindrical member can make the container to which the dispenser is attached appear as a continuous cylindrical body from the dispenser to the dispensing section, thereby improving the overall aesthetic appearance of the container. Furthermore, the cylindrical member can stabilize the expansion and contraction of the air supply space by restricting the direction of operation of the container during expansion and contraction of the air supply space.

[0052] In a discharger like the one shown in

[21] , the fitting groove of the discharge section can stabilize the position of the cylindrical member that fits therein.

[0053] In a container like the one described in

[22] , the user can expand or contract the air intake space of the discharge section of the dispenser to send outside air into the internal space of the container, which is airtightly connected to the air intake space, and the contents of the container can be pushed out by the air sent into the internal space of the container. Therefore, the user of the container can easily dispense the contents.

[0054] In a container like the one shown in

[23] , the liquid flow control unit on the container side and the liquid flow control unit on the dispenser side cooperate. As a result, the container can adjust the discharge volume to a certain range and further suppress the occurrence of unexpected events such as the discharge of contents. [Effects of the Invention]

[0055] The present invention, as shown in any of [1] to

[23] , can provide a highly convenient dispenser and a container equipped with such a dispenser. [Brief explanation of the drawing]

[Figure 11] This is a schematic diagram of a discharge section according to another embodiment of the present invention. [Figure 12] This is a schematic diagram of a discharge section and a connection section according to another embodiment of the present invention. [Modes for carrying out the invention]

[0057] The discharger and container according to embodiments of the present invention will be described below with reference to the attached drawings. Note that the embodiments shown below are examples of the present invention and the present invention is not limited to these embodiments. Furthermore, the discharger according to embodiments of the present invention is denoted by the symbol X, and the container by the symbol Y.

[0058] <Discharger X and container Y> Figure 1(a) is a schematic diagram of the discharger X and container Y, and Figure 1(b) is a cross-sectional view of the discharger X and container Y along line A-A'. For the sake of explanation, the cylindrical member 4 is shown as a transparent member in Figure 1.

[0059] As shown in Figure 1, the container Y comprises a discharge port Y1 and an internal space Y2. That is, contents (not shown) contained in the internal space Y2 can be discharged to the outside through the discharge port Y1. While the contents of container Y are assumed to be liquid or a liquid substance, any object containing a liquid component to a degree that allows for viscosity measurement can be used as the contents of container Y. Furthermore, in the present invention, the discharge port Y1 and the internal space Y2 can have any diameter and shape, as long as they can be airtightly connected to the connection part 2, which will be described later.

[0060] Furthermore, the discharge port Y1 may have a liquid flow control section B that matches its diameter and shape. The liquid flow control section B may optionally use a check valve or an inner plug to restrict the direction or flow rate of the contents.

[0061] A dispenser X is attached to the container Y. The dispenser X comprises a discharge section 1, a connecting section 2, a lid section 3, and a cylindrical member 4.

[0062] The discharge section 1 has an expandable and contractible air supply space 1s, and the connection section 2 is attached to the discharge port Y1 of the container Y, thereby enabling an airtight connection between the internal space Y2 of the container Y and the air supply space 1s. In this invention, the discharge portion 1 and the connecting portion 2 can have any diameter and shape, as long as they do not lose the functions described above. Furthermore, the discharge section 1 and the connection section 2 may have a liquid flow control section B that matches their diameter and shape. The liquid flow control section B may optionally use a check valve or an inner plug to restrict the direction or flow rate of the contents.

[0063] With this configuration, when the volume of the air supply space 1s expands or contracts, outside air is sent into the internal space Y2, which is airtightly connected to the air supply space 1s. The air sent into the internal space Y2 pushes out the contents, so the contents are discharged to the outside through the discharge port Y1 and the discharge section 1.

[0064] <Components of Discharger X> The components of the discharger X and their various embodiments will be described in detail below.

[0065] Figure 2 is a schematic diagram illustrating one embodiment of the discharge section 1 and the connection section 2. The transparent portion is indicated by a dotted line.

[0066] As shown in Figure 2, the discharge section 1 has an enlarged diameter section 11 and an opening 12, and the enlarged diameter section 11 and the opening 12 form an air supply space 1s. Furthermore, since the discharge section 1 is made of an elastic material, the air supply space 1s can be expanded and contracted.

[0067] The enlarged diameter portion 11 has a shape that gradually expands in diameter starting from the end 2e of the connecting portion 2, and the opening 12 has a shape that extends from the enlarged diameter portion 11 while maintaining the maximum diameter of the enlarged diameter portion 11. In other words, the enlarged diameter portion 11 and the opening 12 give the discharge portion 1 an overall shape such as a bowl or a trumpet.

[0068] With a discharge section 1 of this shape, the opening 12 can be pressed against any surface to further expand or contract the air supply space 1s.

[0069] Furthermore, the discharge section 1 may have an opening edge portion 13 that expands in diameter starting from the end 12e of the opening 12. By having an opening edge portion 13, the discharge section 1 can be pressed against any surface to further expand or contract the air supply space 1s.

[0070] Furthermore, the discharge section 1 may have a fitting groove 14 for fitting the aforementioned cylindrical member 4. The discharge section 1 has a fitting groove 14, which allows the position of the cylindrical member 4 to be stabilized, including while the air supply space 1s is being expanded or contracted.

[0071] Furthermore, as shown in Figure 2, the discharge section 1 is formed integrally with a part of the connection section 2.

[0072] The connection part 2 on the discharge part 1 side includes a first connecting body 21a as part of the connection part body 21, and the first connecting body 21a can be attached to the discharge port Y1 of the container Y or to the second connecting body 21b (described later) by any method such as fitting or screwing, thereby enabling an airtight connection between the internal space Y2 of the container Y and the air supply space 1s.

[0073] The first connector 21a can be used alone or attached to the second connector 21b, which will be described later, to constitute the connector 2 or the connector body 21. In other words, the first connector 21a may be directly attached to the outlet Y1 of the container Y as a connector 2 or connector body 21.

[0074] Furthermore, the connection part 2 (first connecting body 21a) on the discharge part 1 side may include an auxiliary discharge port 22, and the auxiliary discharge port 22 may be provided with a liquid flow operation part B (not shown). Furthermore, an auxiliary discharge port 22 and a liquid flow control unit B (not shown) may be provided on the second connecting body 21b, which will be described later.

[0075] By providing multiple liquid flow control parts B, such as check valves and stoppers, in auxiliary discharge ports 22 and discharge port Y1 of container Y, the discharger X can adjust the discharge volume within a certain range and further suppress the occurrence of unexpected discharges and other incidents.

[0076] Figures 3(a) and 3(b) are schematic diagrams illustrating other embodiments of the discharge section 1 and the connection section 2. The transparent portion is indicated by a dotted line. Furthermore, some components common to the discharge section 1 shown in Figure 2 are omitted from the illustration and explanation.

[0077] As shown in Figure 3, the discharge section 1 may have an expanding section 11, a reducing section 15, and an opening 12.

[0078] The enlarged diameter portion 11 has a shape that gradually expands in diameter starting from the end 2e of the connecting portion 2, the reduced diameter portion 15 has a shape that gradually decreases in diameter from the maximum diameter of the enlarged diameter portion 11, and the opening 12 is a shape that extends from the minimum diameter portion of the reduced diameter portion 15.

[0079] With a discharge section 1 of this shape, the opening 12 can be pressed against any surface to further expand or contract the air supply space 1s.

[0080] Furthermore, as shown in Figure 3(b), the discharge section 1 may have an enlarged diameter section 11, a relay section 16, a reduced diameter section 15, and an opening 12.

[0081] The intermediate section 16 has a shape that extends to the starting point of the reduced diameter section 15 while maintaining the maximum diameter of the expanded diameter section 11. This makes it easier to further expand or contract the air supply space 1s when the air supply space 1s is expanded or contracted, mainly by the intermediate section 16 bending.

[0082] Figure 4 is a schematic diagram illustrating another embodiment of the discharge section 1 and the connection section 2. The transparent portion is shown by a dotted line. In addition, some components common to the discharge section 1 shown in Figures 2 and 3 are not shown or explained.

[0083] As shown in Figure 4, the discharge section 1 is formed integrally with a part of the connecting section 2, and the connecting section 2 on the discharge section 1 side has a part of the connecting section body 21 (first connecting body 21a) and a ridge section 24.

[0084] The ridge section 24 is provided with multiple ridges that have a predetermined inclination with respect to the expansion and contraction direction of the air supply space 1s. Furthermore, the direction in which the air supply space 1s expands and contracts is the direction in which the user grips the container Y and tries to press the opening 12 against any surface. Therefore, this can also be described as the direction of the central axis of the container Y, or the direction of the central axis of the discharge section 1 or the connection section 2.

[0085] The ridge portion 24 suppresses deformation of the connection portion 2 that occurs when the air supply space 1s is expanded or contracted, making the connection with the discharge port Y1 of the container Y and the second connecting body 21b, which will be described later, stronger and more airtight. The ridge portion 24 may also be provided on the second connecting body 21b, which will be described later.

[0086] Figures 5(a) and 5(b) are schematic diagrams illustrating other embodiments of the discharge section 1 and the connection section 2. In particular, Figure 5(b) is a diagram showing a cross-section similar to that of Figure 1(b), with the addition of a lid section 3 to Figure 5(a). The transparent portion is indicated by a dotted line. Furthermore, some of the components common to the discharge unit 1 shown in Figures 2-4 are omitted from the illustration and explanation.

[0087] As shown in Figure 5(a), the discharge section 1 is formed integrally with a part of the connecting section 2, and the connecting section 2 on the discharge section 1 side has a part of the connecting section body 21 (first connecting body 21a), an auxiliary discharge port 22, and a connecting pipe 23.

[0088] The first connector 21a can be attached to the discharge port Y1 of the container Y or to the auxiliary discharge port 22 on the second connector 21b side (described later) by any method such as fitting or screwing, thereby enabling an airtight connection between the internal space Y2 of the container Y and the air supply space 1s (e.g., Figure 5(b)).

[0089] The connecting tube 23 includes a tip DE that is inserted into the contents of container Y, a base PE that is attached to the connecting body 21, and a weight portion 23a provided on the tip DE side.

[0090] The connecting pipe 23 can guide the contents of container Y to the discharge port Y1 to which the connecting body 21 is attached. Therefore, the discharger X can discharge the contents of container Y regardless of the orientation of container Y, as long as the tip DE of the connecting pipe 23 is inserted into the contents of container Y. Furthermore, the weight portion 23a on the tip DE side of the connecting tube 23 can assist in inserting the contents of the container Y into the connecting tube 23 even if the orientation of the container Y changes.

[0091] Figure 6 is a schematic diagram illustrating the second connecting body 21b in the connection section 2. The transparent portion is shown by a dotted line.

[0092] As shown in Figure 6, the second connector 21b includes an auxiliary discharge port 22. The auxiliary discharge port 22 may have a liquid flow control section B (not shown). The liquid flow control section B can optionally use a check valve or an inner plug to restrict the flow direction or flow rate of the contents.

[0093] By providing multiple stages of liquid flow control parts B, such as check valves and stoppers, in the auxiliary discharge port 22 and the discharge port Y1 of container Y, the discharger X can adjust the discharge volume within a certain range and further suppress the occurrence of unexpected discharges (Figure 1).

[0094] The second connector 21b can be attached to the discharge port Y1 of the container Y or to the first connector 21a by any method such as fitting or screwing, thereby enabling an airtight connection between the internal space Y2 of the container Y and the air supply space 1s.

[0095] For example, the second connector 21b shown in Figure 6 can be fitted and connected to the first connector 21a by a fitting rib FR, and can be screwed into the discharge port Y1 by a threaded portion ST. Note that the positions and number of the fitted ribs FR and threaded parts ST shown in the example can be changed as needed.

[0096] Furthermore, the auxiliary discharge port 22 may include a protruding portion 22a (Figure 6(b)). Since the protruding portion 22a can protrude into the air supply space 1s (Figure 1), the expansion and contraction length of the air supply space 1s can be limited, and the amount of liquid discharged each time can be adjusted to a certain range.

[0097] Figure 7(a) is a schematic diagram illustrating another embodiment of the discharge section 1 and the connection section 2. The transparent portion is indicated by a dotted line. Furthermore, Figure 7(b) shows a cross-sectional view similar to that in Figure 1(b) when the discharge section 1 and connection section 2 shown in Figure 7(a) are applied to the container Y shown in Figure 1.

[0098] As shown in Figure 7, the connection part 2 (first connecting body 21a) on the discharge part 1 side may include an auxiliary discharge port 22 and a protruding part 22a, and the auxiliary discharge port 22 may be provided with a liquid flow operation part B.

[0099] Furthermore, the protruding portion 22a can impart effects to the discharger X according to its shape. For example, by making the protruding portion 22a a shape that gradually widens toward the air supply space 1s as shown in Figure 7 (a trumpet-like shape), liquid cutoff can be improved.

[0100] Figure 8 is a schematic diagram illustrating the lid 3. The transparent portion is indicated by a dotted line. As shown in Figure 8, the lid portion 3 has a closing portion 31, a closing assist portion 32, and a fixing portion 33.

[0101] An example of a closing part 31 is a projection that plugs the discharge port Y1 of the container Y, or the auxiliary discharge port 22 of the first connector 21a or the second connector 21b. In other words, the closing section 31 closes the path from the discharge port Y1 to the air supply space 1s, thereby suppressing leakage of contents when the lid 3 is attached to the container Y (see Figure 1).

[0102] Examples of the closing auxiliary portion 32 include annular recesses and protrusions provided around the closing portion 31. In other words, the closing auxiliary part 32 can cover the area around the closing part 31 that plugs the discharge port Y1 of the container Y, or the auxiliary discharge port 22 of the first connector 21a or the second connector 21b (Figure 1).

[0103] The closing section 31 and the closing auxiliary section 32 work together to close the path from the discharge port Y1 to the air supply space 1s, thereby enhancing the effect of suppressing leakage of the contents of the container Y. Furthermore, the closing assist part 32 can suppress the expansion and contraction of the air supply space 1s when the lid part 3 is attached to the container Y, thereby suppressing the occurrence of leakage of contents.

[0104] Examples of the fixing part 33 include a suction cup that can be attached to any smooth surface, and a magnet that can be magnetically attached to any magnetic material. In other words, the fixing part 33 fixes the lid part 3 to the installation location and stabilizes the position of the lid part 3 so that it can also be used as a base when the lid part 3 is attached to the container Y, thereby suppressing leakage of the contents of the container Y and tipping over. Furthermore, since the lid 3 is fixed to the installation location, the user can lift the container Y placed on it using the lid 3 as a base, without having to hold the lid 3 with their hand.

[0105] Returning to Figure 1, let's explain the cylindrical member 4. As shown in Figure 1, the cylindrical member 4 is located between the container Y and the dispensing section 1, and its inner diameter is formed to be approximately the same as the outer diameter of the container Y and the diameter of the fitting groove 14 of the dispensing section 1.

[0106] In other words, the cylindrical member 4 makes the container Y to which the discharger X is attached appear as a continuous cylindrical body up to the discharge section 1, improving the overall aesthetic appearance of the container, while also stabilizing the expansion and contraction of the air supply space 1s by restricting the direction of operation of the container Y when the air supply space 1s is expanded or contracted.

[0107] The configurations and functions shown in the above embodiments are merely examples and can be modified in various ways based on design requirements, etc.

[0108] For example, as shown in Figure 9, the discharge portion 1 and the connecting portion 2 may be formed integrally.

[0109] Alternatively, as shown in Figure 10, the lid portion 3 and the cylindrical member 4 may be formed integrally.

[0110] For example, the discharge section 1 may be formed in the shape shown in Figures 11 and 12.

[0111] Specifically, the enlarged diameter portion 11 of the discharge portion 1 may include a flat portion 11a that expands horizontally starting from the end 2e of the connecting portion 2, and an enlarged diameter portion body 11b that gradually expands starting from the end of the flat portion 11a. By giving the discharge portion 1 such a shape, the discharge portion 1 that is deformed when the air supply space 1s expands or contracts can be easily restored to its original shape.

[0112] In addition, the contact portion C between the first connecting body 21a and the second connecting body 21b may be formed to have a predetermined width, in which case the second connecting body 21b may be formed to have a diameter approximately the same as the diameter of the contact portion C. By giving the first connector 21a and the second connector 21b such shapes, the expansion and contraction of the air supply space 1s (deformation of the discharge section 1 by pressing) can be performed stably, and the aesthetic appearance of the container can be maintained.

[0113] Furthermore, the various embodiments of the component configurations described above can be arbitrarily combined to constitute the present invention. [Explanation of Symbols]
