Description

  The present invention includes an inner container having an opening for extracting contents and an outer container for movably holding the inner container, and extracting the contents stored in the inner container by exposing the opening by moving the inner container. It relates to an extraction container that can be made.

  Conventionally, various containers for storing various contents including confectionery and medicines have been proposed depending on the type of contents and intended use. For example, various types of containers having a function of preventing child accidental ingestion are known.

  As for such a function, for example, Patent Document 1 discloses an inner cap that is screwed onto a container neck to close it, an outer cap that covers the outer periphery of the inner cap, and a spring provided between the outer cap and the inner cap. The child proof cap is configured so that the teeth that transmit the rotation of the outer cap and the inner cap by spring force are disengaged and idled, and when it is desired to open the cap, the outer cap is pushed down and turned. (See paragraph 0003 of the same document).

  The document also includes a child proof cap provided with teeth on the outer circumference of the inner cap and an elastically deformable opening operation portion having a pawl portion on the outer cap. Even if the outer cap is rotated without pressing the stopper operation part, the claw part slips over the teeth of the inner cap, while if the stopper operation part is pressed and elastically deformed, the pawl part and the teeth mesh. The inner cap is also rotated and opened together with the outer cap (see claim 1 of the same document).

  By the way, although all of the thing of patent document 1 cannot be opened even if it moves as usual in the state as it is, it can be switched to the state which can be opened by applying force. In other words, in order to prevent the child from opening easily, it is necessary to switch to the openable state only after applying a certain amount of force. For this reason, those adopting such a configuration have a problem that it is difficult to open not only for children but also for adults with weak power such as elderly people.

  An object of the present invention is to solve the above-mentioned problems. A new extraction container that enables the extraction of contents by releasing the function without exerting a strong force while exerting the child proof function. The purpose is to provide.

The present invention includes a storage space for storing contents, and an inner container having an opening in the peripheral wall for extracting the contents of the storage space;
An extraction container having an outer wall that is closed at one end by a bottom and has an outer peripheral wall that is open at the other end, and that holds the inner container movably along a central axis of the outer peripheral wall;
The outer peripheral wall has one end-side male screw provided on the bottom side, and a through-hole provided through the outer peripheral wall and adjacent to the thread of the one end-side male screw,
The bottom portion includes an elastic portion including an engaged portion that is linked to an engaging portion provided in the inner container and is maintained in a state where the opening is surrounded by the outer peripheral wall,
The elastic container has a protrusion that protrudes from the through hole to the outside of the outer peripheral wall and presses inward of the outer peripheral wall to release the linkage between the engaging portion and the engaged portion. It is.

  The through hole is preferably located between adjacent screw threads in the one end-side male screw.

The outer peripheral wall has the other end side male screw having the same form as the one end side male screw at the other end of the outer peripheral wall,
Furthermore, it is preferable to have a cap provided with a female screw corresponding to the one end-side male screw and the other end-side male screw.

  Preferably, an elastic body that biases the inner container toward the other end of the outer peripheral wall is provided between the bottom and the inner container.

  The extraction container of the present invention includes an inner container having an opening for extracting contents and an outer container for movably holding the inner container, and one end provided on the outer wall of the outer container on the bottom side of the outer container. A side male screw and a through hole provided adjacent to the thread of the one end side male screw are provided, and the bottom is maintained in a state where the opening is surrounded by the outer peripheral wall in association with the engaging portion provided in the inner container. An elastic part having an engaged part is provided, and the elastic part projects from the through hole to the outside of the outer peripheral wall and is pressed toward the inner side of the outer peripheral wall to link the engaging part and the engaged part. Protrusions that release the are provided. That is, in the extraction container of the present invention, a through hole is provided adjacent to the thread and a projection for releasing the engagement between the inner container and the outer container is projected from the through hole. Since the engagement between the inner container and the outer container cannot be released unless the projection is pushed in, the child proof function can be effectively exhibited. Further, in the present invention, since the child proof function is exerted so as not to touch the protrusion itself, it is not necessary to give a strong elastic force to the elastic portion connected to the protrusion. For this reason, even an adult with weak force can easily disengage the inner container from the outer container and extract the contents.

  In addition, when the through hole is provided adjacent to the thread, it may be the start position or the end position of the thread, but in this case, one side of the through hole is adjacent to the thread, but vice versa. There will be no threads on the side. Even in this case, although the protrusion is difficult to be pressed, by positioning the protrusion between the adjacent threads, both sides of the protrusion can be adjacent to the thread, so that the child proof function can be more reliably exhibited.

  On the outer peripheral wall, in addition to the one end side male screw described above, the other end side male screw having the same form as the one end side male screw is provided, and further, a cap having a female screw corresponding to the one end side male screw and the other end side male screw is provided. Therefore, normally, the cap is attached so as to engage with the male screw on the other end side, and when the contents are to be extracted, the cap is engaged with the male screw on the one end side, and the protrusion is pushed in with the female screw of the cap. Can be exposed. That is, since the projection can be pressed using the cap, the usability is improved. In addition, the cap can be held in the outer container even when there is no need to take out the contents, so there is no possibility of losing the cap. Furthermore, since the procedure of removing the cap engaged with the other end side male screw and engaging with the one end side male screw is difficult to understand unless the operation is understood, the child proof function is effectively maintained.

  When providing an elastic body that urges the inner container toward the other end of the outer peripheral wall between the bottom and the inner container, the inner container automatically moves and the opening is exposed if the projection is pressed. Usability is improved.

In one embodiment of the extraction container according to the present invention, the contents cannot be extracted, (a) is a sectional view in side view, (b) is a sectional view along A-A shown in (a). is there. (A) is an arrow view along arrow B shown in FIG. 1 (a), and (b) is an arrow view (bottom plan view) of the bottom along arrow C shown in (a).

It is a figure explaining the condition which inclines an extraction container from the state of FIG. 4, and extracts a content.

  Hereinafter, an embodiment of an extraction container according to the present invention will be described with reference to the drawings. In the present specification and the like, “upper” and “lower” refer to the state in which the lid indicated by reference numeral 3 is positioned upward and the bottom cover indicated by reference numeral 6 is positioned downward as shown in FIG. The direction at.

  The extraction container of this embodiment includes an inner container 1, an outer container 4, an elastic body 7, and a cap 8. The inner container 1 in this embodiment includes an inner container body 2 that functions as a peripheral wall of the inner container 1 and a lid 3. The outer container 4 includes an outer container body 5 that functions as an outer peripheral wall of the outer container 4 and a bottom cover 6 that functions as a bottom portion of the outer container 4.

  The inner container body 2 has a generally bottomed cylindrical shape, and is connected to a substantially D-shaped bottom portion 2a that is formed by cutting a part of a disk in a straight line and an outer edge of the bottom portion 2a. A lower peripheral wall 2b whose cross-sectional shape forms a D-shape, a stepped wall 2c connected to the upper end of the lower peripheral wall 2b and extending in the horizontal direction, and a cylindrical shape connected to the lower peripheral wall 2b and the stepped wall 2c An upper peripheral wall 2d is provided. Here, a storage space M for storing the contents C is formed inside the bottom portion 2a, the lower peripheral wall 2b, the stepped wall 2c, and the upper peripheral wall 2d. 1 is a circular shape having a relatively large particle diameter, the size and shape are not limited to those shown in the figure. Further, the step wall 2c is provided with an inward claw portion 2e (engagement portion) extending downward, and the upper peripheral wall 2d is arranged along the central axis O of the inner container body 2 on the outer peripheral surface thereof. An extending vertical rib 2f is provided. Further, an opening 2g for extracting the contents C is provided above the upper peripheral wall 2d.

  The lid body 3 includes a disc-like lid plate 3a and an annular fitting wall 3b provided on the lower surface of the lid plate 3a. The fitting wall 3b is formed in a size that fits inside the upper peripheral wall 2d. By fitting the fitting wall 3b into the upper peripheral wall 2d, the upper portion of the storage space M is closed, and the lid 3 is the contents. The instrument body 2 is fitted and held.

  The outer container body 5 generally has a cylindrical shape with both ends open, and includes a cylindrical outer peripheral wall 5a that is one size larger than the inner container body 2. A longitudinal groove 5b for accommodating the longitudinal rib 2f is provided on the inner circumferential surface of the outer peripheral wall 5a. As a result, the inner container body 2 is movable along the central axis O and held against rotation with respect to the outer container body 5. Further, one end-side male screw 5c is provided on the outer peripheral surface of the outer peripheral wall 5a on the side (one end side) to which the bottom cover 6 is attached. Further, the outer peripheral wall 5a is provided with a through hole 5d penetrating the outer peripheral wall 5a adjacent to the thread of the one end side male screw 5c as shown in FIG. In addition, the through hole 5d in the present embodiment is provided between adjacent screw threads in the one end side male screw 5c, and both the upper and lower sides of the through hole 5d are adjacent to the screw thread. 5d may be moved upward or downward with respect to the one end-side male screw 5c so that only one of the upper or lower side in the through hole 5d is adjacent to the screw thread. A holding portion 5e configured to increase the inner diameter and fit and hold the bottom cover 6 is provided on one end side of the outer peripheral wall 5a.

  The other end side male screw 5f having the same form as the one end side male screw 5c is provided on the other end side of the outer peripheral surface of the outer peripheral wall 5a. Note that the one end-side male screw 5c and the other end-side male screw 5f have the same configuration means that the shape of the screw thread and the pitch of the screw thread are the same, and the starting point of the screw in the direction around the central axis O is the same. They may be different from each other, and the number of threads may be different from each other. Further, a flange 5g extending in a direction approaching the central axis O is provided on the inner peripheral surface on the other end side of the outer peripheral wall 5a.

  The bottom cover 6 includes a bottom plate 6a having a disc shape, and an annular wall 6b connected to the outer edge of the bottom plate 6a and fitted and held by the holding portion 5e. The bottom plate 6a is provided with a rib 6c that rises upward. As shown in FIG. 2B, the ribs 6c of the present embodiment have an arc shape in plan view, and a total of three ribs 6c are provided in a uniform arrangement around the central axis O.

  As shown in FIG. 1A, the bottom cover 6 includes a plate-like elastic piece 6d (elastic portion) extending upward from the bottom plate 6a below the stepped wall 2c. The elastic piece 6d of the present embodiment can be tilted in a direction approaching the central axis O with the connecting portion with the bottom plate 6a being thick and the base being reinforced, and starting from this connecting portion. An outward claw portion 6e (engaged portion) that engages with the inward claw portion 2e is provided above the elastic piece 6d. Furthermore, the outer surface of the elastic piece 6d is provided with a protrusion 6f extending in a direction away from the central axis O and protruding from the through hole 5d to the outside of the outer peripheral wall 5a. The outer end portion of the protrusion 6f is located at a position that does not exceed the apex of the thread of the one-end-side male screw 5c (approximately the same position as the apex or closer to the central axis O than the apex). Further, as shown in FIG. 2B, an inclined portion 6g is provided at the outer end portion of the protrusion 6f. The position where the inclined portion 6g is provided on the projection 6f is the side where the mating screw first contacts the projection 6f when it is assumed that the mating screw is moved in the tightening direction with respect to the one-end male screw 5c.

  In this embodiment, the elastic body 7 is a coil spring (made of metal or resin) wound in a spiral. As shown in FIG. 1A, the elastic body 7 is disposed inside the rib 6c between the bottom 2a and the bottom plate 6a. Thereby, the inner container main body 2 is always urged | biased upwards. The elastic body 7 only needs to move the inner container body 2 upward, and the material and shape thereof are not limited. For example, a thin plate-like elastic piece provided integrally with the inner container body 2 or the bottom cover 6 may be used.

  The cap 8 includes a disc-shaped cap top wall 8a and a cap peripheral wall 8b that surrounds the outer peripheral wall 5a and is connected to the outer edge of the cap top wall 8a. A female screw 8c corresponding to the one end side male screw 5c and the other end side male screw 5f is provided on the inner peripheral surface of the cap peripheral wall 8b. That is, the cap 8 can be attached to the side where the other end side male screw 5f is provided, or can be attached to the side where the one end side male screw 5c is provided.

  In the extraction container having such a configuration, when the inward claw portion 2e and the outward claw portion 6e are engaged as shown in FIG. 1A, the opening 2g is surrounded by the outer peripheral wall 5a. Therefore, it is maintained in a state where the contents cannot be extracted (contents cannot be extracted). Further, the protrusion 6f protrudes from a through hole 5d provided between the threads of the one-end-side male screw 5c, and the outer end portion of the protrusion 6f is positioned so as not to exceed the apex of these threads. Even if a finger touches the side male screw 5c, the protrusion 6f is in a state where it is difficult to be pressed.

  When the contents C are extracted, the cap 8 attached to the side on which the other end side male screw 5f is provided is removed and attached to the side on which the one end side male screw 5c is provided as shown in FIG. At this time, the screw thread of the female screw 8c of the cap 8 advances along the screw thread of the one-end male screw 5c, so that the protrusion 6f is pressed by the screw thread of the female screw 8c. Since the protrusion 6f in this embodiment is provided with the inclined portion 6g shown in FIG. 2B, the thread of the female screw 8c first hits the inclined portion 6g. For this reason, the progress of the internal thread 8c is not hindered, and the cap 8 can be smoothly rotated. When the projection 6f is pressed, the elastic piece 6d tilts in a direction approaching the central axis O as shown in FIG. 3, and the engagement between the inward claw portion 2e and the outward claw portion 6e is released. The inner container body 2 that has been urged by the movement moves along the central axis O while the vertical rib 2f is guided by the vertical groove 5b, and stops at a position where the vertical rib 2f contacts the flange 5g. At this position, the opening 2g is exposed from the outer peripheral wall 5a as shown in FIG. 3 and FIG. 4, so if the outer container body 5 is tilted with the opening 2g facing downward as shown in FIG. The contents C can be extracted.

  The extraction container according to the present invention is not limited to the above-described embodiments, and may be variously modified within the scope according to the claims, or may be added with other configurations. For example, the “elastic portion” described above has been described as the elastic piece 6d connected to the protrusion 6f in the present embodiment, but various other types can be applied. Specifically, the elastic piece 6d of this embodiment is a cantilever support type that extends in the vertical direction and can be tilted with its lower end as a starting point. For example, the elastic piece 6d extends in the circumferential direction. A both-side support type structure may be used in which the center portion of the elastic piece is bent inward in the radial direction when the protrusions are pressed while supporting the both ends of the plate. Moreover, it is not restricted to what is integrally provided in a bottom cover like embodiment mentioned above, For example, it is good also as a structure which urges | biases the protrusion provided as another member with a coil spring etc., for example.
