Description

  The present invention relates to a biochemical container used for containing a biochemical substance, and more particularly to a biochemical container having a structure in which an opening at one end of a container member is opened and closed with a lid member.

  Biochemical containers are used to store biochemical substances at sites such as biochemical experiments. Such a biochemical container includes, for example, a vertically long cylindrical container member whose upper end is open, and a disk-shaped lid member that closes the opening of the container member so as to be freely opened and closed.

  A normal biochemical container is formed in a size that can be held with one hand. Such a biochemical container is formed, for example, in a structure in which a container member and a lid member are screwed together with a screw structure. However, in such a biochemical container, it is difficult to open and close the lid member while holding the container member with one hand.

  As a biochemical container that solves such a problem, there is a product in which the outer edge portion of the upper end of the container member and the outer edge portion of the lid member are connected at one end by a hinge mechanism. When opening and closing such a biochemical container, for example, the container member is grasped with one hand so that the axial direction is the vertical direction, and the portion of the lid member opposite to the hinge mechanism is displaced vertically with the thumb. It will be.

Currently, there are various proposals as container structures that can be used for biochemical containers as described above (see, for example, Patent Documents 1 to 4).
JP 2003-292004 A JP 2000-313453 A Japanese Patent Application Laid-Open No. 07-315402 Japanese Utility Model Publication No. 02-144552

  The biochemical container as described above needs to securely seal the opening of the container member with the lid member. For this reason, it is not easy to open the closed lid member from the container member with only one hand. Moreover, if the outer edge of the lid member is displaced upward with the thumb while the container member is held with one hand, the lid member is likely to be suddenly opened along with the release of the sealed state. In this case, the biochemical substance jumps out of the container member and the fingers are contaminated, and there is a risk that the biochemical containers and biochemical substances are contaminated by the fingers.

  Even when the fingers are not contaminated, hold the container member with one hand and open the lid member with the other hand, or displace the outer edge of the lid member upward with the thumb as described above. If it is opened, the deposit on the finger surface falls into the container when the finger passes over the opened container, and this fallen substance may cause contamination of biochemical substances in the container. is there.

  For example, in the container described in Patent Document 1, the lid member is urged in the opening direction by a hinge mechanism and is held in a closed state by a lock mechanism. For this reason, a lid member can be easily opened only by releasing a lock mechanism with a finger.

  However, in a biochemical container, it is necessary to securely seal the container member with a lid member. For this reason, it is difficult to open the lid member only by the resilient force of the hinge mechanism as described above. In order to open the sealing lid member with the elastic force of the hinge mechanism, the hinge mechanism needs a strong elastic force.

  In this case, a dedicated leaf spring or the like is required for the hinge mechanism, and the structure becomes complicated. Furthermore, since the lid member is suddenly opened when the sealed state is released, there is an increased possibility that the biochemical substance jumps out and the fingers and surroundings are contaminated.

  The present invention has been made in view of the above-described problems, and provides a biochemical container having a structure capable of releasing the sealed state of the container member without directly displacing the outer edge of the lid member with fingers. To do.

  A first biochemical container of the present invention is a biochemical container having a container member having one end opened and a lid member for closing the opening of the container member so that the opening of the container member can be freely opened and closed. A hinge mechanism that swingably supports the lid member between the position to be opened and the position to be opened, and one end connected to one outer surface of the container member and the lid member and the other end to the other outer surface An opening assisting member that faces and elastically curves, and a direction changing mechanism that converts stress in a direction acting on the opening assisting member from the outside into stress acting on the lid member in the opening direction.

  Therefore, in the biochemical container of the present invention, the opening at one end of the container member is closed by the lid member so as to be freely opened and closed. When the opening assisting member is pressed from the outside in such a closed state, the stress is converted into the opening direction by the direction changing mechanism and acts on the lid member. For this reason, the sealed state of the container member can be released.

  A second biochemical container according to the present invention is a biochemical container having a container member having one end opened and a lid member for closing the opening of the container member so that the opening of the container member can be freely opened and closed. A hinge mechanism that swingably supports the lid member between the position to be opened and the position to be opened, and one end connected to one outer surface of the container member and the lid member and the other end to the other outer surface An opening assisting member that is opposed and elastically curved, and a direction changing mechanism that converts an inward displacement of at least a part of the opening assisting member into a displacement in an opening direction of at least a part of the lid member. .

  Therefore, in the biochemical container of the present invention, the opening at one end of the container member is closed by the lid member so as to be freely opened and closed. When the opening assisting member is pressed and displaced from the outside in such a closed state, the displacement is converted into the opening direction by the direction changing mechanism and acts on the lid member. For this reason, the sealed state of the container member can be released.

  The first lid unit of the present invention is a lid unit that is mounted on the container body of the biochemical container of the present invention, and includes a lid member, a frame-shaped member that is mounted on the outer surface of one end of the container body, and a frame A hinge mechanism that is connected to the cover member and swingably supports the cover member, and one end is connected to one outer surface of the frame member and the cover member and the other end is connected to the other outer surface. An opening assisting member that faces and elastically curves, and a direction changing mechanism that converts stress in a direction acting on the opening assisting member from the outside into stress acting on the lid member in the opening direction.

  The second lid unit of the present invention is a lid unit that is mounted on the container body of the biochemical container of the present invention, the lid member, a frame-shaped member that is mounted on the outer surface of one end of the container body, and a frame A hinge mechanism that is connected to the cover member and swingably supports the cover member, and one end is connected to one outer surface of the frame member and the cover member and the other end is connected to the other outer surface. An opening assisting member that is opposed and elastically curved, and a direction changing mechanism that converts an inward displacement of at least a part of the opening assisting member into a displacement in an opening direction of at least a part of the lid member. .

  The various components of the present invention do not necessarily have to be independent of each other. A plurality of components are formed as a single member, and a single component is formed of a plurality of members. It may be that a certain component is a part of another component, a part of a certain component overlaps with a part of another component, or the like.

  In the biochemical container of the present invention, when the opening auxiliary member is pressed from the outside with the opening at one end of the container member being opened and closed by the lid member, the stress is converted into the opening direction by the direction changing mechanism. Acts on the lid member. For this reason, the sealing state of the lid member closing the container member can be released. Therefore, in order to open the lid member that seals the container member, it is not necessary to displace the edge of the lid member directly with fingers. For this reason, the finger is contaminated with the biochemical substance contained in the container member, the biochemical substance inside the container member is contaminated with the fallen material from the finger surface during the opening operation of the lid member, etc. Can be prevented.

  An embodiment of the present invention will be described below with reference to FIGS. Further, in the present embodiment, as shown in FIG. However, this is provided for convenience in order to simply explain the relative relationship of the components, and does not limit the direction during the manufacture or use of the product implementing the present invention.

  The biochemical container 100 according to the present embodiment opens a container member 110 that is open at one end, a lid member 120 that closes the opening of the container member 110 so as to be openable and closable, and a position at which the opening of the container member 110 is closed. The hinge mechanism 130 that swingably supports the lid member 120 at a position, and one end connected to one outer surface of the container member 110 and the lid member 120 and the other end opposed to the other outer surface The opening assisting member 140 that is elastically curved, and converts stress in a direction acting on the opening assisting member 140 from the outside into stress acting on the lid member 120 in the opening direction, and at least one of the opening assisting member 140. A direction changing mechanism 150 that converts the inward displacement of the section into the displacement in the opening direction of at least a part of the lid member 120.

  More specifically, the container member 110 has a cylindrical container body 111 having an upper end that is one end opened. A separate lid unit 160 is attached to the upper end of the container body 111.

  The lid unit 160 has an annular frame-shaped member 161 attached to the outer surface of one end of the container body 111 as a part of the container member 110. A hinge mechanism 130 is connected to the frame member 161.

  Therefore, the lid unit 160 is also mounted with the opening assisting member 140 and the direction changing mechanism 150 together with the lid member 120 described above. The lid unit 160 is attached to the container body 111 by, for example, a screw structure (not shown).

  The lid member 120 is formed in a disc shape, and an annular portion 121 that seals the upper end opening of the container body 111 from the inside is formed on the lower surface thereof. The opening auxiliary member 140 is formed in a plate shape elongated in the vertical direction.

  The opening assisting member 140 has an upper end connected to the front portion of the outer surface of the lid member 120, and the lower end of the opening auxiliary member 140 faces the front portion of the outer surface of the frame-shaped member 161 when the lid member 120 is closed. The opening auxiliary member 140 has a thin upper end portion connected to the lid member 120.

  For this reason, as shown in FIG. 1 and FIG. 3, when the opening assisting member 140 is pressed from the front, the lower end is elastically displaced rearward. The opening assisting member 140 has a lower end portion 141 formed in a semi-cylindrical shape.

  On the other hand, a semi-cylindrical convex portion 162 is formed on the front surface of the frame-shaped member 161. The lower end portion 141 of the opening assisting member 140 is positioned above the convex portion 162 of the frame-shaped member 161 by a distance equal to or less than the radius of the semi-cylindrical shape.

  For this reason, the outer peripheral surface of the lower end portion 141 of the opening assisting member 140 is in contact with the outer peripheral surface of the convex portion 162 of the frame-shaped member 161 in the rear half portion, and is displaced rearward, which is the upper side in the opening direction of the lid member 120. It functions as a sloping slope.

  On the other hand, the outer peripheral surface of the convex portion 162 of the frame-shaped member 161 is in contact with the outer peripheral surface of the lower end portion 141 of the opening assisting member 140 in the upper half, and is displaced rearward, which is the upper side in the opening direction of the lid member 120. It functions as a sloping slope.

  The direction changing mechanism 150 that converts the stress in the direction acting on the opening assisting member 140 from the front to the stress acting on the lid member 120 upward by the lower end portion 141 and the convex portion 162 that function as described above. It has been realized.

In the biochemical container 100 of the present embodiment, as shown in FIG. 3, when the total height a of the annular portion 121 of the lid member 120 that seals the container main body 111 of the container member 110 and the opening assisting member 140 are pressed. The distance b at which the lower end portion 141 and the convex portion 162 are relatively displaced is
a <b
Satisfied with the relationship.

  Further, the hinge mechanism 130 is elastically biased in the direction to open the lid member 120, and the opened lid member 120 is substantially perpendicular to the opening of the container member 110 as shown in FIG. It is held elastically at the position where it swings.

  Note that the lid member 120 is held at a substantially right angle means that, for example, the lid member 120 in an open state does not hinder access to the container main body 111 such as a pipette (not shown), and a plurality of biochemistry Even when the container 100 is erected on a stand or the like, it is sufficient that the opened lid member 120 does not collide with the lid member 120 of the adjacent biochemical container 100. Specifically, 70 ° It may be in the range of ~ 120 °.

  Further, as described above, the hinge mechanism 130 that elastically biases the lid member 120 in the opening direction and elastically holds the lid member 120 at a predetermined angle has been conventionally known. Is disclosed.

  Furthermore, in the biochemical container 100 of the present embodiment, as shown in FIG. 2, semicircular convex portions 122 are formed downward from the left and right of the outer edge portion of the lid member 120. For this reason, the frame-shaped member 161 is formed with semicircular concave portions 164 corresponding to the convex portions 122 described above on the left and right sides of the outer surface.

  In the configuration as described above, the biochemical container 100 according to the present embodiment is held with one hand in the same manner as a conventional biochemical container (not shown). However, as shown in FIGS. 1A and 2A, when opening the lid member 120 closed by the container member 110, the opening assisting member 140 is pressed with a thumb (not shown).

  Then, the lower half portion 141 of the lower end portion 141 of the opening assisting member 140 that is elastically curved is pressed against the upper half portion of the convex portion 162 of the container member 110, so that FIG. 1 (b) and FIG. 3 (b). As shown, the lower end portion 141 of the opening assisting member 140 is displaced above the convex portion 162 of the container member 110.

  As a result, the lid member 120 is displaced upward together with the opening assisting member 140. Since the displacement distance b is larger than the total height a of the annular portion 121 of the lid member 120 that seals the container member 110, the sealed state of the container member 110 by the lid member 120 is released.

  Then, the lid member 120 is opened upward by the elastic bias of the hinge mechanism 130, and is opened at a substantially right angle from the opening of the container member 110 as shown in FIGS. 1 (b) and 2 (b). Held in a state of elasticity.

  In the biochemical container 100 of the present embodiment, the closed state of the lid member 120 with respect to the container member 110 can be released by pressing the opening assisting member 140 with a finger as described above.

  Therefore, in order to open the lid member 120 that seals the container member 110, it is not necessary to displace the edge of the lid member 120 directly with fingers. For this reason, the finger is contaminated with a biochemical substance (not shown) accommodated in the container member 110, and the fallen object (not shown) from the finger surface during the opening operation of the lid member 120 causes the container member 110 to be contaminated. It is possible to prevent the biochemical substance inside the container from being contaminated, the finger that displaces the outer edge of the lid member 120 upwards from contacting the upper edge of the container member 110, and the like.

  In particular, in the biochemical container 100 of the present embodiment, the opening assisting member 140 formed downward from the outer edge of the lid member 120 is located on the outer surface of the container member 110, so that the fingers are the container member 110. It is possible to effectively prevent contact with the upper edge portion.

  Furthermore, since the lid member 120 is elastically biased in the opening direction by the hinge mechanism 130, the lid member 120 released from the sealed state with respect to the container member 110 as described above can be automatically opened. .

  Even if the lid member 120 is not completely opened by the elastic force of the hinge mechanism 130, the lid member can be displaced by moving the opening assisting member 140 located on the outer surface of the container member 110 upward with fingers. 120 can be opened.

  For example, in a conventional biochemical container (not shown), in order to open the lid member, when the outer edge portion of the lid member is displaced upward with a finger of one hand holding the container member, the finger is placed on the container member. Since it is easy to contact an edge part, there existed a possibility that contamination might generate | occur | produce in a container member and biochemical substance by this contact.

  However, in the biochemical container 100 of the present embodiment, the lid member 120 can be opened by displacing the opening assisting member 140 upward with fingers as described above, so that the fingers can more effectively move the fingers of the container member 110. It is possible to prevent the stain from occurring due to contact with the upper edge.

  Moreover, the hinge mechanism 130 elastically holds the opened lid member 120 at a position that is swung substantially perpendicularly from the opening of the container member 110. Therefore, the open lid member 120 does not hinder access to the container main body 111 such as a pipette, and even if a plurality of biochemical containers 100 are erected on a stand or the like, The lid member 120 does not collide with the lid member 120 of the adjacent biochemical container 100.

  Further, as described above, the direction changing mechanism 150 that changes the direction of the stress is formed by the lower end portion 141 of the opening assisting member 140 and the convex portion 162 of the container member 110. For this reason, the direction change mechanism 150 which acts appropriately can be realized with a simple structure.

  In addition, the overall height a of the annular portion 121 of the lid member 120 that seals the container main body 111 of the container member 110 is smaller than the step b generated between the lower end portion 141 of the opening assisting member 140 and the convex portion 162 of the container member 110. For this reason, the sealing between the container member 110 and the lid member 120 can be reliably released by the direction changing mechanism 150 including the lower end portion 141 and the convex portion 162.

  Furthermore, the container main body 111 and the lid unit 160 are formed separately. For this reason, the container main body 111 that requires resistance to biochemical substances and the like, and the lid unit 160 that requires sealing by the annular portion 121 and elasticity of the hinge mechanism 130 are individually made of optimum materials. Can be formed.

  Suitable materials for the container body 111 include, for example, polyethylene, polypropylene, poly-4-methyl 1-pentene, polystyrene, nylon, polyethylene terephthalate, polybutylene terephthalate, and the like. Examples of suitable materials for the lid unit 160 include polyethylene, polypropylene, nylon, and polystyrene.

  In addition, the lid member 120 is detachably engaged with the opening of the container body 111. For this reason, even if the container main body 111 and the lid unit 160 are separate bodies as described above, the container main body 111 can be reliably sealed by the lid member 120.

  The present invention is not limited to the present embodiment, and various modifications are allowed without departing from the scope of the present invention. For example, in the above embodiment, the open auxiliary member 140 is in contact with the semicylindrical convex portion 162 of the frame-shaped member 161 at the semicylindrical lower end portion 141.

  However, like the biochemical container 300 illustrated in FIG. 4, a semicylindrical convex portion 311 is formed on the rear surface of the lower end of the opening assisting member 310, and this is the semicylindrical convex portion 162 of the frame-shaped member 161. You may contact.

  Furthermore, in the above embodiment, the lower half of the semi-cylindrical lower end portion 141 on the rear surface of the lower end of the opening auxiliary member 140 connected to the lid member 120 at the upper end, and the semi-cylindrical convex portion 162 of the front surface of the container member 110 are formed. An example in which the direction changing mechanism 150 is realized by contacting the upper half portion is illustrated.

  However, as in the biochemical container 200 illustrated in FIG. 5, an inclined surface 201 that is displaced upward and rearward is formed on the front surface of the container member 202, and the lower end of the opening assisting member 203 faces the inclined surface 201. Therefore, the direction changing mechanism 204 may be realized.

  Further, as in the biochemical container 210 illustrated in FIG. 6, an inclined surface 211 that is displaced upward and rearward is formed on the rear surface of the lower end of the opening auxiliary member 212, and the convex surface of the front surface of the container member 213 is formed on the inclined surface 211. The direction changing mechanism 215 may be realized by the portions 214 facing each other.

  Further, as in the biochemical container 220 illustrated in FIG. 7, a slope 221 that is displaced upward and forward is formed on the front surface of the lid member 222, and a lower opening auxiliary member connected to the container member 223. The direction changing mechanism 225 may be realized by the upper end of the 224 facing the inclined surface 221 of the lid member 222.

  Further, as in the biochemical container 230 illustrated in FIG. 8, an inclined surface 231 that is displaced forward in the upper direction is formed at the upper end of the opening assisting member 233 that is connected to the container member 232 at the lower end. The direction changing mechanism 236 may be realized by the convex portion 235 on the front surface of the lid member 234 facing the inclined surface 231.

  Note that by adjusting the angles of the inclined surfaces 201, 211, 221, and 231 as described above, the ratio of converting the stress and displacement of the pressure into the stress and displacement below can be adjusted.

  Furthermore, in the said form, it illustrated that the container main body 111 and the cover unit 160 were formed in the different body. However, like the biochemical container 240 illustrated in FIG. 9, the container member 241, the lid member 242, and the hinge mechanism 243 may be integrally formed. In addition, as a material which can be used suitably in such an aspect, polyethylene, a polypropylene, nylon, a polystyrene etc. are mentioned, for example.

  Moreover, in the said form, it illustrated that the cover member 120 of the cover unit 160 was sealed by the container main body 111. FIG. However, like the biochemical container 250 illustrated in FIG. 10, the lid member 254 may be sealed with the frame-like member 253 of the lid unit 252 attached to the container body 251.

  Further, in the above embodiment, since the distance b of displacement by the direction changing mechanism 150 is larger than the total height a of the annular portion 121 of the lid member 120 that seals the container main body 111 of the container member 110, the direction changing mechanism 150 causes the lid member 120 to move. Is illustrated as being fully open.

  However, in this case, there is a possibility that the container body 111 cannot be satisfactorily sealed by the lid member 120. Therefore, if this becomes a problem, the above-described total height a may be larger than the displacement distance b (not shown).

  In this case, the lid member 120 cannot be completely opened by the direction changing mechanism, but the sealed state can be released. Therefore, for example, the lid member 120 that has been released from the sealed state can be easily and safely opened simply by displacing it upward with fingers.

  Even in such a case, the lid member 120 can be opened by displacing the opening assisting member 140 positioned on the outer surface of the container member 110 with the fingers, so that the fingers can move the upper edge of the container member 110. It is possible to effectively prevent contamination from coming into contact with the part.

  The release of the sealed state here means that the state where the entire outer peripheral surface of the annular portion 121 of the lid member 120 is in close contact with the inner peripheral surface of the container main body 111 is released. More specifically, the state may be changed from a state in which the lower surface of the lid member 120 is in contact with the upper surface of the container body 111 to a state in which the lid member 120 is separated by a predetermined distance.

  Further, when the lid member 120 that has been sealed by the direction changing mechanism 150 in this way is opened with a finger, for example, as shown in FIG. The convex portion 122 may be gripped by the thumb and middle finger of one hand gripping the container member 110 (not shown).

  In this case, the lid member 120 can be easily opened even when the lid member 120 is not completely opened by the direction changing mechanism as described above. In addition, since the fingers that open the lid member 120 are covered by the convex portions 122, it is possible to effectively prevent the fingers from being contaminated by biochemical substances.

  Further, like the biochemical container 260 illustrated in FIG. 11, a strong cylindrical engagement portion 263 is formed on the upper portion of the annular portion 262 of the lid member 261, and a multi-stage seal-like airtight portion 264 is formed on the lower portion. It may be formed.

  In this case, the hermeticity of the lid member 261 can be ensured by the airtight portion 264. Nevertheless, by making the total height a of the engaging portion 263 smaller than the displacement distance b by the direction changing mechanism 150, the engagement by the engaging portion 263 can be easily released by the direction changing mechanism 150. For this reason, the lid member 261 can be completely opened by the direction changing mechanism 150 while ensuring the sealing property of the lid member 261.

  Further, as in the biochemical container 270 illustrated in FIG. 12, a concave portion 273 having a triangular cross section is formed on the outer peripheral surface of the lower end scale of the annular portion 272 of the lid member 271, and is engaged with the concave portion 273. The convex portion 274 may be formed on the inner peripheral surface of the container member 275.

  In this case, the sealing property of the lid member 271 can be ensured by the ring portion 272 having a sufficient height. Nevertheless, the displacement c required for releasing the engagement between the concave portion 273 and the convex portion 274 is made smaller than the distance b of the displacement by the direction changing mechanism 150, whereby the engagement between the concave portion 273 and the convex portion 274 is changed to the direction changing mechanism. 150 can be easily released. For this reason, the lid member 271 can be completely opened by the direction changing mechanism 150 while ensuring the sealing property of the lid member 271.

  Moreover, in the said form, when the direction change mechanism 150 was located on the opposite side to the hinge mechanism 130, one end of the lid member 120 was displaced and opened by one direction change mechanism 150.

  However, like the biochemical container 280 illustrated in FIG. 13, the pair of direction changing mechanisms 150 may be formed on the left and right. In this case, for example, while holding the container body 111 with one hand, the left and right edges of the lid member 120 are moved by the pair of direction changing mechanisms 150 by pressing the pair of opening assisting members 140 from both sides with the thumb and the index finger. At the same time, it can be displaced upward and opened.

  Also in this case, similarly to the convex portion 122 shown in FIG. 2, the opening assisting member 140 of the lid member 120 can be held with the finger of the opposite one hand. Therefore, it is possible to prevent the finger that opens the lid member 120 from being contaminated by the biochemical substance using the opening assisting member 140 as a cover.

  For this reason, the biochemical container 280 and the biochemical substance are contaminated by contaminated fingers, and the biochemical substance inside the container member 110 is contaminated by falling objects from the finger surface when the lid member 120 is opened. Can also be prevented.

  Furthermore, in the said form, the lower end part 141 of the opening auxiliary member 140 connected with the cover member 120 in the said form, and the upper half part of the convex part 162 of the container member 110 contact | abut and displace, and a direction change mechanism It is illustrated that 150 is realized.

  However, like the biochemical container 290 illustrated in FIG. 14, one end of the opening auxiliary member 291 that is curved outward in an arc shape is connected to one of the lid member 292 and the container body 293, and the other end is connected to the other. The direction changing mechanism 295 may be realized by engaging with the convex portion 294 or the like.

  In this case, as shown in FIG. 14B, since the opening assisting member 291 curved in an arc shape expands when pressed from the outside, the lid member 292 is separated from the container main body 293 and opened by this expansion. Can do.

  Needless to say, the above-described embodiment and a plurality of modifications can be combined within a range in which the contents do not conflict with each other.
