[0003] [Patent Document 1] Japanese Patent Application Publication No. 2023-78976 Summary of the Invention [Problem to be solved by the invention]

[0004] In the container disclosed in Patent Document 1, a relatively large force is required to attach and detach the lid to and from the container body.

[0005] The present invention has been made to solve such problems, and its object is to provide a container in which the force required to attach and detach the lid is relatively small. [Means for solving the problem]

[0006] The container according to the present invention comprises a container body having an opening formed at its upper end, and a lid. The container body is configured to contain a medicine. The lid is configured to be removably attached to the container body. When the lid is attached to the container body, the lid covers the opening. The container body includes a bottom surface and a first side surface having a male thread formed thereon. The first side surface extends upward from the outer periphery of the bottom surface. On the outer periphery of the first side surface, an installation portion configured to come into contact with the lower end of the lid is formed below the male thread. The lid includes a top surface and a second side surface having a female thread formed thereon and configured to couple with the male thread. One or more evaporation holes are formed in the top surface. The second side surface extends downward from the outer periphery of the top surface. A plurality of protrusions are formed at the lower end of the second side surface. When the lid is attached to the container body, each of the plurality of protrusions comes into contact with the installation portion.

[0007] In this container, when the lid is attached to the container body, each of the multiple protrusions contacts the installation portion. Therefore, with this container, the frictional force generated when attaching or detaching the lid is smaller than in a case where, for example, multiple protrusions are not formed on the lower end of the second side surface portion and the entire lower end of the second side surface portion contacts the installation portion, and therefore the force required to attach or detach the lid can be reduced.

[0008] In the container, a plurality of protrusions may be formed at a predetermined interval from each other on the lower end of the second side surface portion.

[0009] With this container, multiple protrusions are formed at a predetermined distance from each other, which reduces the variation in the tightness of the screws depending on the position when the lid is attached to the container body, compared to when multiple protrusions are formed in biased positions.

[0010] In the container, each of the plurality of protrusions may have an arc shape when viewed from the front.

[0011] With this container, each of the multiple protrusions has an arc-shaped configuration, and therefore the contact area between each protrusion and the installation portion when the lid is attached to the container body can be made smaller than when, for example, each of the multiple protrusions has a trapezoidal shape.

[0012] In the container, the installation portion may be configured by a protrusion formed around the entire outer circumferential surface.

[0013] In the above container, a step may be formed on the outer surface of the first side portion below the installation portion, and the circumferential length of the outer surface of the first side portion above the step may be shorter than the circumferential length of the outer surface of the first side portion below the step.

[0014] With this container, even if the container were to tip over and the medicine (e.g., liquid medicine) were to leak out of the container, the medicine would remain in the step, thereby preventing the medicine from reaching the bottom of the container body.

[0015] In the above container, when the drug is contained in the container body, the opening may be sealed with a release film, and when the lid body is attached to the container body, the upper end of the first side portion and the back surface of the top surface portion do not have to come into contact.

[0016] With this container, when the lid is attached to the container body, the upper end of the first side portion does not come into contact with the back surface of the top surface portion, thereby reducing the possibility of the release film being torn due to contact between the top surface portion and the release film.

[0017] In the container, the evaporation hole may be formed from the top surface portion to the second side surface portion.

[0018] According to this container, the evaporation holes are formed from the top surface to the second side surface, so the area of ​​the evaporation holes is larger than when the evaporation holes are formed only on the top surface, thereby improving the evaporation effect of the drug.

[0019] In the above container, each of the one or more evaporation holes may be constituted by a slit extending in a predetermined direction, and the upper surface portion may include a reinforcing plate portion extending in a direction perpendicular to the predetermined direction and passing through the center of the upper surface portion.

[0020] According to this container, the upper surface includes a reinforcing plate portion extending in a direction perpendicular to the slits, so that the strength of the lid can be maintained to a certain degree even if the area of ​​each evaporation hole is large.

[0021] In the container, a plurality of ribs each extending in a predetermined direction may be formed from the top surface portion to the second side surface portion, and a slit may be formed between two adjacent ribs.

[0022] With this container, each rib is formed from the top surface to the second side surface, so the area of ​​the slit is larger than when each rib is formed only on the top surface, thereby improving the evaporation effect of the medicine.

[0023] In the container, the lid may have a circular shape in plan view, and the diameter of the lid may be 10 cm or more.

[0024] With this container, even if the diameter of the lid is 10 cm or more and the user has difficulty gripping the lid depending on the size of their hand, the frictional force generated when attaching or detaching the lid is small, so the user can easily attach or detach the lid. [Effects of the Invention]

[0025] According to the present invention, it is possible to provide a container in which the force required to attach and detach the lid is relatively small. [Brief explanation of the drawings]

[0027] An embodiment according to one aspect of the present invention (hereinafter also referred to as "the present embodiment") will be described in detail below with reference to the drawings. Note that the same or corresponding parts in the drawings are designated by the same reference numerals, and their description will not be repeated. Furthermore, for ease of understanding, each drawing is drawn schematically with objects appropriately omitted or exaggerated.

[0028] [1. Configuration] <1-1. Overall structure of the container> FIG. 1 is a perspective view schematically illustrating a container 10 according to the present embodiment. In this specification, unless otherwise specified, "upper" and "lower" are defined based on the state of use of the container 10 shown in FIG. 1. As shown in FIG. 1, the container 10 has a generally cylindrical shape and includes a container body 100 and a lid 200. The container body 100 contains, for example, a volatile chemical. Examples of the chemical include deodorants, air fresheners, insecticides, fungicides, disinfectants, insect repellents, and insect repellents. The chemical may have a deodorizing effect on odors caused by pets such as dogs or cats. The chemical may be held in a geometric shape, such as a sphere, a rectangular parallelepiped, or a star, or in a special shape such as an animal, plant, or anime character. In this embodiment, the chemical is held in a bead-like object. Furthermore, in this embodiment, a large number of bead-like balls holding such a chemical are contained within the container body 100. The container body 100 has an opening at its upper end, which will be described in detail later.

[0029] The lid body 200 is detachably attached to the container body 100. For example, the user rotates the lid body 200 clockwise relative to the container body 100, thereby attaching the lid body 200 to the container body 100. Alternatively, the user rotates the lid body 200 counterclockwise relative to the container body 100, thereby removing the lid body 200 from the container body 100. For example, if the chemical agent is a deodorizer for odors caused by pets, the lid body 200 may be provided with a screw-type attachment / detachment mechanism, thereby preventing the lid body 200 from being unintentionally opened by a pet.

[0030] When the lid body 200 is attached to the container body 100, the opening at the upper end of the container body 100 is covered by the lid body 200. As will be described in detail later, a plurality of volatilization holes are formed in the upper surface of the lid body 200. The drug contained in the container body 100 volatilizes to the outside of the container 10 through the opening formed at the upper end of the container body 100 and the plurality of volatilization holes formed in the upper surface of the lid body 200.

[0031] Before the drug stored in container 10 is used, for example, the opening formed at the upper end of container body 100 is sealed with a gas-impermeable release film. In this state, lid body 200 is attached to container body 100. A user first removes lid body 200 from container body 100, peels off the release film attached to container body 100, and then reattaches lid body 200 to container body 100 to start using the drug.

[0032] If a large force is required to attach or detach the lid 200 to the container body 100, the force applied to the container 10 when attaching or detaching the lid 200 may be inadvertently applied, causing the medicine contained in the container body 100 to unintentionally leak out of the container body 100. To prevent such an occurrence, the container 10 according to the present embodiment is devised to relatively reduce the force required to attach or detach the lid 200. The configurations of the container body 100 and the lid 200 will be described in detail below.

[0033] <1-2. Container body configuration> FIG. 2 is a perspective view schematically showing the container body 100 from diagonally above. FIG. 3 is a perspective view schematically showing the container body 100 from diagonally below. With reference to FIGS. 2 and 3, the container body 100 is made of, for example, a transparent resin. In this case, the user can visually check the medicine contained in the container body 100. An opening O1 is formed at the upper end of the container body 100. The container body 100 has a cylindrical shape with a bottom, and includes a bottom surface portion 110 and a side surface portion 120. The bottom surface portion 110 has a substantially circular shape in a plan view, and is raised upward as it approaches the center.

[0034] The side surface portion 120 has a substantially cylindrical shape and extends upward from the outer periphery of the bottom surface portion 110. A step portion 122 is formed in the side surface portion 120 at a position above the center position in the up-down direction. The step portion 122 extends in the circumferential direction of the side surface portion 120 and is formed around the entire circumference of the side surface portion 120. The diameter of the side surface portion 120 above the step portion 122 is shorter than the diameter of the side surface portion 120 below the step portion 122. Furthermore, the circumferential length of the outer periphery of the side surface portion 120 above the step portion 122 is shorter than the circumferential length of the outer periphery of the side surface portion 120 below the step portion 122. Even if the drug (e.g., drug solution held in beads) leaks out of the container 10 due to, for example, the container 10 being overturned, the drug remains in the step portion 122, thereby preventing the drug from reaching the bottom surface portion 110 of the container body 100. A male screw 126 is formed on the side surface portion 120 at a position above the step portion 122. The male screw 126 may be, for example, a double-start screw, or may be a multiple-start screw with three or more threads (for example, a triple-start screw).

[0035] Furthermore, a mounting portion 124 is formed in the side surface portion 120 at a position above the step portion 122 and below the male thread 126. The mounting portion 124 is configured so that the lower end of the lid body 200 comes into contact with the mounting portion 124 when the lid body 200 is attached to the container body 100. The mounting portion 124 extends in the circumferential direction of the side surface portion 120, and is formed around the entire circumference of the side surface portion 120. The mounting portion 124 is configured by a protruding portion that protrudes radially outward from the outer circumferential surface of the side surface portion 120. The thickness of the mounting portion 124 is approximately uniform, and the upper surface of the mounting portion 124 is flat.

[0036] <1-3. Lid structure> Fig. 4 is a perspective view schematically showing the lid body 200 from diagonally above. Fig. 5 is a view schematically showing the lid body 200 from above (a view schematically showing the surface of the lid body 200). With reference to Figs. 4 and 5, the lid body 200 is made of, for example, resin. The lid body 200 includes an upper surface portion 210 and a side surface portion 220.

[0037] The upper surface portion 210 has a substantially circular shape in a plan view. A plurality of ribs 212, each extending in a first direction, are formed on the upper surface portion 210. The upper surface portion 210 also has a reinforcing plate portion 214, which extends in a second direction perpendicular to the first direction and passes through the center of the upper surface portion 210. Both ends of the reinforcing plate portion 214 are located on the outer periphery of the upper surface portion 210.

[0038] Each rib 212 extends from a position on the outer periphery of the top surface portion 210 via the reinforcing plate portion 214 to another position on the outer periphery of the top surface portion 210. That is, both ends of each rib 212 are located on the outer periphery of the top surface portion 210. At least some of the ribs 212 extend from the top surface portion 210 to the side surface portion 220. A slit S1 is formed between two adjacent ribs 212. Each slit S1 functions as a vaporization hole. In the container 10, at least some of the slits S1 (volatilization holes) are formed from the top surface portion 210 to the side surface portion 220. Therefore, compared to when the slits S1 are formed only in the top surface portion 210, the area of ​​the slits S1 is larger, improving the vaporization effect of the medicine. The width of each slit S1 is shorter than, for example, the particle size of a bead-shaped medicine. This prevents the medicine in the container 10 from leaking out of the container 10 if the container 10 falls over.

[0039] The reinforcing plate 214 includes a reinforcing plate main body 214A extending in the second direction and a circular portion 214B formed in the center of the top surface 210. The diameter of the circular portion 214B is longer than the width (length in the first direction) of the reinforcing plate main body 214A. For example, when the lid 200 is manufactured by resin molding and the lid 200 is removed from a resin molding device by suction, the circular portion 214B can be used as a suction position. The width of the reinforcing plate main body 214A is longer than the width of each rib 212. The width of the reinforcing plate main body 214A is, for example, 1.2 to 5 times the width of each rib 212, preferably 1.5 to 4 times, and more preferably 2 to 3 times. Because top surface portion 210 includes reinforcing plate portion 214 extending in a direction (second direction) perpendicular to slits S1, the strength of lid body 200 is maintained to a certain degree even if the area of ​​each slit S1 is large. Therefore, for example, if the chemical agent is a deodorizer for odors caused by pets, container 10 is unlikely to break even if a pet puts its weight on container 10.

[0040] FIG. 6 is a perspective view schematically showing the lid 200 from diagonally below. FIG. 7 is a diagram schematically showing the lid 200 from below (a diagram schematically showing the back surface of the lid 200). Referring to FIGS. 6 and 7, a female thread 224 is formed in the side surface portion 220 at a position below the center position in the up-down direction. The female thread 224 may be configured as a double-start thread or a multiple-start thread having three or more threads (e.g., a triple-start thread). The female thread 224 is configured to be coupled with a male thread 126 formed in the side surface portion 120 of the container body 100. In addition, a plurality of (e.g., 16) protrusions 222 are formed at the lower end of the side surface portion 220. Each of the plurality of protrusions 222 protrudes downward from the lower end of the side surface portion 220. The plurality of protrusions 222 are formed at predetermined intervals (equidistant intervals) from one another in the circumferential direction of the lower end of the side surface portion 220. When viewed from the front, each of the protrusions 222 has an arcuate shape. The reason why a plurality of protrusions 222 are formed on the lower end of the side surface portion 220 will now be described.

[0041] [2. Reasons for forming a convex part on the lid] As described above, a user who purchases a medicine contained in the container 10 begins using the medicine by, for example, removing the lid 200 from the container body 100, peeling off the release film attached to the container body 100, and reattaching the lid 200 to the container body 100. If a large force is required to attach or detach the lid 200 to the container body 100, the force applied to the container 10 when attaching or detaching the lid 200 may be inadvertently applied to the container 10, resulting in the medicine contained in the container body 100 being unintentionally released outside the container body 100. For example, if the diameter of the lid 200 is 10 cm or more and the user has small hands, the lid 200 may be difficult for the user to grip. In such cases, the above-described situation is particularly likely to occur. In addition, the above-described situation is also likely to occur when the amount of resin used in the container body 100 and the lid 200 is reduced to reduce environmental impact, thereby reducing the overall rigidity.

[0042] FIG. 8 is a side view schematically illustrating container 10. Referring to FIG. 8, in container 10, when lid 200 is attached to container body 100, each of multiple protrusions 222 contacts the upper surface of installation portion 124. Therefore, in container 10, the frictional force generated when lid 200 is attached or detached is smaller than in a case where, for example, multiple protrusions 222 are not formed on the lower end of side surface 220 of lid 200 and the entire lower end of side surface 220 contacts the upper surface of installation portion 124. As a result, the force required to attach or detach lid 200 in container 10 is reduced. Therefore, container 10 prevents a situation in which a force applied to container 10 when lid 200 is attached or detached acts erroneously, causing the medicine contained in container body 100 to unintentionally leak out of container body 100.

[0043] Furthermore, as described above, in the container 10, the multiple protrusions 222 are formed at a predetermined distance from each other, and therefore, the variation in the tightness of the screws depending on the position when the lid body 200 is attached to the container body 100 is reduced compared to when the multiple protrusions 222 are formed at biased positions.

[0044] Furthermore, as described above, in the container 10, the shape of each of the plurality of protrusions 222 is arc-shaped, and therefore, compared to when the shape of each of the plurality of protrusions 222 is trapezoidal, the contact area between each of the protrusions 222 and the installation portion 124 when the lid 200 is attached to the container body 100 is smaller. Therefore, the frictional force generated when attaching or detaching the lid 200 is smaller.

[0045] Fig. 9 is a diagram schematically showing a cross section of container 10. Referring to Fig. 9, in container 10, when lid 200 is attached to container body 100, the upper end of side surface portion 120 of container body 100 and the back surface of top surface portion 210 of lid 200 are separated by length L1. In container 10, when lid 200 is attached to container body 100, the upper end of side surface portion 120 of container body 100 and the back surface of top surface portion 210 of lid 200 do not come into contact, thereby reducing the possibility of the release film being torn due to contact between top surface portion 210 of lid 200 and the release film.

[0046] [3. Features] As described above, in container 10 according to the present embodiment, when lid 200 is attached to container body 100, each of multiple protrusions 222 comes into contact with installation portion 124. Therefore, with container 10, the frictional force generated when lid 200 is attached or detached is smaller than when, for example, multiple protrusions 222 are not formed on the lower end of side surface portion 220 and the entire lower end of side surface portion 220 comes into contact with installation portion 124, and therefore the force required to attach or detach lid 200 can be reduced.

[0047] 4. Other Embodiments The concept of the above embodiment is not limited to the embodiment described above. Hereinafter, examples of other embodiments to which the concept of the above embodiment can be applied will be described.

[0048] <4-1> In the above embodiment, the installation portion 124 is formed around the entire circumference of the side surface 120 of the container body 100. However, the installation portion 124 does not necessarily have to be formed around the entire circumference of the side surface 120 of the container body 100. It is sufficient that the installation portion 124 is provided at least in the portion where each of the protrusions 222 is located when the lid 200 is attached to the container body 100.

[0049] <4-2> In the above embodiment, a plurality of slits S1 are formed in the lid body 200 as evaporation holes. However, the evaporation holes formed in the lid body 200 do not necessarily have to be slits S1. The evaporation holes formed in the lid body 200 may be holes, and the shape of the holes may be circular or polygonal. Furthermore, the number of evaporation holes formed in the lid body 200 is not particularly limited. It is sufficient that one or more evaporation holes are formed.

[0050] <4-3> In the above embodiment, the installation portion 124 is configured by a protrusion that protrudes radially outward from the side surface portion 120 of the container body 100. However, the function of the installation portion 124 does not necessarily have to be realized by such a protrusion. The function of the installation portion 124 may be realized by, for example, the step portion 122. That is, when the lid body 200 is attached to the container body 100, each of the multiple protrusions 222 provided on the lower end of the side surface portion 220 of the lid body 200 may come into contact with the step portion 122.

[0051] In the above embodiment, the shape of each of the plurality of protrusions 222 in a front view is an arc. However, the shape of each of the plurality of protrusions 222 in a front view does not necessarily have to be an arc. The shape of each of the plurality of protrusions 222 in a front view may be, for example, a trapezoid, a triangle, or a rectangle.

[0052] The above describes exemplary embodiments of the present invention. That is, the detailed description and the accompanying drawings are disclosed for the purpose of illustrative explanation. Therefore, some of the components described in the detailed description and the accompanying drawings may be non-essential components for solving the problems. Therefore, just because these non-essential components are described in the detailed description and the accompanying drawings, it should not be immediately recognized that these non-essential components are essential.

[0053] Furthermore, the above-described embodiments are merely illustrative of the present invention in all respects. Various improvements and modifications to the above-described embodiments are possible within the scope of the present invention. For example, at least a portion of the configuration of any of the embodiments may be combined with at least a portion of the configuration of any of the other embodiments. In other words, when implementing the present invention, specific configurations can be appropriately adopted depending on the embodiment. [Explanation of symbols]
