Description

  The present invention relates to a lidded container in which an openable lid provided on a top surface or the like of a container body is opened by a pushing operation of an operation member.

  As a wet tissue container packed in a bag, an operation member that can be pushed into the container body is attached, and the operation member and the lid that closes the wet tissue outlet are engaged to restrain the lid in the closed position. A one-push type lidded container is known in which the operation member and the lid are disengaged by pushing the operation member and the lid is opened (see Patent Document 1). In addition, in a container with a lid in which the operation member is formed integrally with the container body, a container with a lid incorporating a locking mechanism that makes it impossible to push down the operation member is known in order to prevent the lid from being opened due to an erroneous operation. (See Patent Document 2). Furthermore, in a container with a lid in which the operation member is formed integrally with the container main body, a pressing member that pushes up the lid from the lower surface side in accordance with the pushing operation of the operation member is provided on the operation member ( (See Patent Document 3).

Japanese Patent Laid-Open No. 9-58725 JP 2001-146247 A JP 2000-25805 A

  The locking mechanism described in Patent Literature 2 is operated by attaching a slider as a lock member, which is manufactured as a separate component to the operation member to be pushed in, to the container body, and disengaging the slider from the operation member. The lock and release of the member are switched. However, since the slider does not act directly on the lid, the operation member and the lid may be disengaged and the lid may open depending on the degree of elastic deformation of the operation member. Further, when the operation member is provided as a separate part with respect to the container main body, it is necessary to separately assemble the operation member and the lock member to the container main body, and it takes time to assemble the container.

  Therefore, an object of the present invention is to provide a container with a lid that can reliably prevent the opening of the lid due to an erroneous operation and can easily attach the operation member and the lock member to the container body.

  The present invention will be described below. In order to facilitate understanding of the present invention, reference numerals in the accompanying drawings are appended in parentheses, but the present invention is not limited to the illustrated embodiment.

  The container (1) with a lid of the present invention includes a container body (2) having a content outlet (10), a lid (4) attached to the container body so as to open and close the outlet, Lid urging means (5) disposed between the container main body and the lid to urge the lid in the opening direction, and meshed with the lid to close the lid against the lid urging means. A container with a lid, comprising: an operating member (6) attached to the container body in an operable state between a closed position to be held in a state and an open position in which the meshing with the lid is released; The operating member has a direction from which the lid is closed with respect to the lid biased by the lid biasing means opposite to the direction in which the lid opens with respect to the lid in the closed state. The operation direction of the operation member from the closed position to the open position while meshing with the lid A locking position that abuts the locking surface of the container body from a direction from the open position to the closed position of the operation member and disables the operation member from the closed position to the open position. A locking member movable between a closed position and a release position allowing the operation member to move from the closed position to the open position apart from each of the closed lid and the locking surface of the container body. 7) is attached, the lock member is provided movably between the lock position and the release position on the back side of the operation surface (30a) provided on the operation member, and the operation member is A guide surface (30b) that is in contact with the lock member is formed on the back surface side of the operation member and is moved from the closed position to the open position by pushing the operation surface. A spring portion (32) that protrudes and biases the operating member to the closed position is provided, and the lock member is inserted into a groove portion (37) provided in the spring portion, thereby contacting the guide surface and the lock. The above-described problem is solved by being slidably supported between the position and the release position.

  According to this invention, by moving the lock member to the lock position, the operation member cannot be operated to the open position, and unintentional opening of the lid is prevented. Since the lock member restrains the lid at the lock position, the effect of preventing the lid from opening is enhanced as compared with the case where only the operation member is restrained by the lock member. Since the lock member is attached to the operation member, the operation member and the lock member can be assembled in advance before being attached to the container body, and the labor required for mounting on the container body is reduced. Since the lock member is provided on the back surface side of the operation surface, the lock member can be hidden from the operation surface so as not to stand out. If a groove portion is formed in a part of the spring portion provided on the back surface side of the operation member and the lock member is inserted, the lock member is slidably held along the guide surface on the back surface side with respect to the operation surface.

  In the container with a lid of the present invention, the operation surface of the operation member may be exposed on the outer surface side of the container body. In this case, the operation surface can be sufficiently exposed to the outer surface side of the container, and the operability is not impaired.

  The lock member is movable between the lock position and the release position while being supported by the operation member so that relative movement with respect to the operation member is prevented in the same direction as the direction in which the operation surface is pushed. It may be provided. In this case, the operation member and the lock member can be displaced (moved) integrally with respect to the pushing direction of the operation member. Therefore, the operation member can be pushed into the open position via the lock member.

  A guide surface (30b) in contact with the lock member is formed on the back surface side of the operation member, and a spring portion (32) that protrudes from the guide surface and biases the operation member to the closed position is provided. The lock member may be slidably supported between the lock position and the release position while being in contact with the guide surface by being inserted into a groove portion (37) provided in the spring portion.

  A retaining means (43a, 43b, 45, 47) for preventing the locking member from coming off from the groove of the operating member may be provided. By providing the retaining means, it is possible to prevent the lock member from falling off due to an erroneous operation.

  A shaft portion (35) divided by a slit (35a) is provided on the back surface side of the operation member, and a groove portion (42) fitted to the shaft portion is provided on the lock member, the groove portion of the operation member. A claw portion (43a, 43b) that narrows the width of the groove portion may be provided as the retaining means in the groove portion. According to this aspect, when the lock member is inserted into the groove portion of the operation member, the claw portion on the lock member side and the shaft portion are brought into contact with each other, and the shaft portion is elastically deformed in a direction in which the diameter is reduced so that the slit is narrowed. After getting over the claw part, the shaft part can be returned to its original diameter by elastic restoring force. In order to remove the lock member from the operation member, it is necessary to elastically deform the shaft portion so as to narrow the slit, and the shaft portion is appropriately prevented from coming off.

  The groove portion of the lock member includes a first holding portion (42a) into which the shaft portion is fitted when the lock member is in the release position, and the claw portion when the lock member is in the lock position. And the second holding portion (42b) into which the shaft portion is fitted. In this case, the lock member can be held at the release position or the lock position with an appropriate force depending on whether the shaft portion is fitted to the first holding portion or the second holding portion.

  A step portion (38) is provided on the back surface side of the operation member, and the locking member is used as the groove portion of the operation member on the surface (40a) facing the operation member of the lock member as the retaining means. A protrusion-like stopper (45) that can be engaged with the stepped portion with respect to the direction from which the locking member is pulled out and extends in a wedge shape with respect to the direction in which the locking member is inserted into the groove portion of the operating member may be provided. . According to this aspect, when the lock member is inserted into the groove portion of the operation member, the groove portion of the operation member is gradually enlarged by the wedge-shaped stopper, and the stopper can pass through the groove portion. After that, when the lock member is moved in the direction to be extracted from the operation member, the stopper is engaged with the stepped portion and the lock member is prevented from coming off.

  The lock member may be provided with a claw portion (47) that protrudes to the side in the extraction direction toward the extraction direction of the lock member from the groove of the operation member as the retaining means. According to this aspect, when the lock member is inserted into the groove portion of the operation member, the claw portion is elastically deformed inward and passes through the groove portion. Thereafter, when the lock member is moved in the direction to be extracted from the operation member, the claw portion is elastically deformed outward and cannot pass through the groove portion of the operation member, thereby preventing the lock member from coming off.

  The lock member may be provided with a finger hook portion (41) that is located at an end portion in the extraction direction with respect to the groove portion of the operation member and protrudes from the operation surface of the operation member. Thus, if a finger hook part is provided, a lock member can be easily operated from the outer surface side of a container. Further, when the finger-hanging portion is protruded from the outer surface of the container body, the lock member can be operated more easily. When the lock member is moved from the lock position to the release position, the lock member moves away from the lid, and the finger-hanging portion is further pulled out from the operation member. The pushing force can be reduced and the lid can be opened with a light force.

  The container body may be formed in a constricted shape as viewed from the outlet side, and the operation member may be disposed in the constricted portion. By giving the container body a constricted shape, the container body can be easily grasped. In addition, when a shrink film or the like is wrapped around the outer periphery of the container main body so as to include the constricted portion, the film floats up from the container main body at the constricted portion, and the operation member and the lock member disposed inside the container main body are The film can be prevented from being damaged by rubbing away. If the lock member is held in the lock position, even if the finger hooking portion or the operation member of the lock member is pushed in by the film, the operation member does not move to the open position. In particular, when a spring portion is provided on the back side of the operation member, it is possible to prevent deterioration of the spring performance due to the sag of the spring portion by preventing the operation member from moving to the open position in the packaged state. it can.

  A leg portion (46) that contacts the locking surface (25b) of the container body at the lock position may be provided on the back surface side of the lock member. By bringing the leg portion into contact with the locking surface, the operation member cannot be pushed in when the lock member is in the lock position.

  One end formed at the front edge of the lid facing the operation member when the lid is in the closed state, retreating from the surface of the front edge on the operation member side as the surrounding surface Is provided with a locking recess (4j) that is closed or open at both ends, and the locking member is inserted into the locking recess when the lid is closed and the locking member is moved to the locking position, A locking portion (44) that escapes from the locking recess when the locking member is moved to the release position may be provided. If the locking portion is inserted into the locking recess of the lid in accordance with the movement to the locking position, the opening of the lid can be reliably prevented by the lock member. By ensuring a sufficient amount of insertion, the lid can be securely closed even when the lid or the operating member is elastically deformed.

  The operation member or the lock member may be provided with a push-up portion (34) that comes into contact with the lid and pushes up the lid when the operation member is operated from the closed position to the open position. According to this aspect, even when the resistance at the time of opening the lid is increased due to the contents biting between the lid and the container main body, the lid can be pushed up and reliably opened.

  The container body may be provided with a strap attachment portion (14) to which a strap (110) can be attached. By attaching the strap, the container main body is not limited to be placed on a horizontal plane, but can be stored in a manner suspended along a wall or the like.

  A phosphorescent material may be included in at least one of the operation member and the lock member. By including a phosphorescent material in these members, the operation part when the lid is opened emits light in the dark, and the user can easily open the lid. Further, since the operation member and the lock member are small and have a small volume as compared with the lid and the container body, even if a phosphorescent material is mixed with these, the mixing amount is small, which is advantageous in terms of cost.

  As described above, according to the present invention, by moving the lock member to the lock position, the operation member cannot be operated to the open position, and the lock member restrains the lid at the lock position. Unintentional opening of the lid due to, for example, can be reliably prevented. Since the lock member is attached to the operation member, the operation member and the lock member can be assembled in advance before being attached to the container body, and the operation member and the lock member can be reduced by reducing the troubles when mounting the container body. Can be easily attached to the container body.

  As shown in these drawings, a container 1 with a lid includes a container main body 2, a bottom lid 3 that closes an opening on the bottom surface side of the container main body 2, and a top surface 2a side of the container main body 2 (upper surface side in FIG. 1). ), A push button 6 as an operation member operated to open the upper lid 4, and a lock 7 as a lock member for restraining the push button 6. The container body 2, the bottom lid 3, the upper lid 4, the push button 6 and the lock 7 are resin molded products. When the bottom lid 3 is removed from the container body 2, the bottom surface of the container body 2 opens almost entirely, and a wet tissue package can be attached to the inside of the container body 2 from the opening.

  Here, the package will be described. As shown in FIG. 17, the package 100 includes a plurality of wet tissues 102... 102 as contents in a bag 101 having a sealing property continuously from the opening 103 by a predetermined number (for example, one by one). It is folded and accommodated so that it can be taken out. The opening 103 is closed with a seal 104, and the seal 104 is peeled off during use (that is, when accommodated in the container 1).

  As is clear from FIG. 1 (b), an outlet 10 is formed in the upper part of the container body 2. A predetermined number of wet tissues 102 accommodated in the package 100 in the container 1 can be drawn out from the outlet 10. As is well known, the take-out port 10 is provided with a flap 11 for holding the end of the next wet tissue 102 that is pulled up as the wet tissue 102 is taken out. The shape of the flap 11 is not limited to that shown in the figure, and various changes may be made. When the opening 103 of the package 100 has a function equivalent to that of the flap 11, the flap 11 may be omitted.

  Next, the external features of the container 1 will be described. As apparent from FIGS. 2 and 3, the container body 2 is formed in a shape with the center portion narrower than both ends in the left-right direction when viewed from the vertical direction, and the bottom lid 3 is also formed in the center along the container body 2. The part is formed in a constricted shape. The push button 6 is disposed at the constricted portion. By giving the container 1 such a constricted shape, there is an advantage that the center portion of the container 1 can be easily grasped. A stack line 13 is provided on the outer periphery of the container body 2. The stack line 13 is formed by protruding the lower portions of the side surfaces 2b to 2e of the container body 2 outward by a predetermined amount. The stack line 13 engages with the lower end of the upper container main body 2 when a plurality of container main bodies 2 are stacked one above the other, and generates an appropriate gap between the container main bodies 2.

  As is clear from FIG. 1, a ring portion 14 as a strap attachment portion is provided on the right side surface 2 d of the container body 2. A strap 110 can be tied to the ring portion 14. By attaching the strap 110, the container 1 can be hung on a hook or the like. For example, when the wet tissue 102 is used for an infant, the container 1 can be hooked and stored in a crib. Note that the ring portion 14 is not shown in FIG. The ring portion 14 is not limited to the position shown in FIG. 1 and may be provided at an appropriate position.

  Next, the configuration of the upper lid 4 and the parts involved in opening / closing thereof will be described. The upper lid 4 is provided so that the take-out port 10 can be opened and closed by fitting pivot shafts 4c (see FIG. 9) provided at both ends of the rear end portion 4b to the container body 2 so as to be pivotable. . The upper surface 4a of the upper lid 4 is bulged so as to draw a curved surface in which the top surface 2a of the container body 2 and the upper surface 4a of the upper lid 4 are integrally continuous when the upper lid 4 is closed (FIG. 4). reference). As shown in FIGS. 1B, 6, and 8, a plate spring 5 is provided between the container body 2 and the upper lid 4 as a lid biasing unit that biases the upper lid 4 in the opening direction. . The leaf spring 5 is preferably composed of an elastic member such as natural or synthetic rubber. However, the container of this invention is not limited to what was comprised with these materials. For example, the leaf spring 5 may be formed using spring steel or the like instead of the rubber material. The lid biasing means is not limited to a plate-like one.

  As shown in detail in FIG. 9, one end of the leaf spring 5 is fixed to the leaf spring mounting hole 2 f of the container body 2, and the other end is attached to the spring mounting shaft 4 d of the upper lid 4 via a cap 15. In a state where the upper lid 4 is closed, the leaf spring 5 is bent and accommodated in the spring accommodating groove 2g of the container body 2 so as to draw a loop. When the upper lid 4 is opened, the leaf spring 5 extends, and the upper lid 4 is held in an almost upright state by its elastic restoring force (see FIG. 8).

  A first recess (top surface recess) 21 is formed on the top surface 2 a of the container body 2 so as to match the outer periphery of the upper lid 4, and the second recess 22 is further lowered in the first recess 21. Is provided. The outlet 10 and the flap 1 described above are formed on the bottom plate 22 a of the second recess 22. As shown in FIG. 1B, an oval or oval closing rib 4 f corresponding to the second recess 22 is formed on the back surface 4 e of the upper lid 4. When the upper lid 4 is closed, the closing rib 4f enters immediately inside the side wall 22b of the second recess 22, so that the periphery of the outlet 10 is doubly surrounded by the closing rib 4f and the side wall 22b. A practically sufficient sealing property is secured with respect to the periphery of the outlet 10.

  As shown in FIGS. 1B and 5, a claw portion 4 h for holding the upper lid 4 in a closed state is formed at the center of the front end of the upper lid 4. Further, a lock hole 4j as a locking recess is formed immediately below the claw portion 4h of the upper lid 4. Note that the lock hole 4j may be formed as a hole with one end closed. Further, notches 4k are formed on both sides of the claw portion 4h. These claw portions 4 h, lock holes 4 j and notches 4 k are provided corresponding to the push buttons 6 and the locks 7. Hereinafter, the push button 6 and the lock 7 will be described.

  11 to 13 show details of the push button 6, FIG. 11 is a plan view, FIG. 12 is a front view, and FIG. 13 is a bottom view. As shown in these drawings, the push button 6 has a plate-like main body 30 having an operation surface 30 a, a support shaft 31 protruding from both ends of the main body 30, and a guide surface 30 b on the back side of the main body 30. Spring portion 32 projecting in the form of a claw, claw portion 33 disposed at the center of rear edge portion 30c of main body portion 30, push-up portions 34 provided on both sides of claw portion 33, claw portion 33 and spring portion 32. And a pair of reinforcing ribs 36 extending from the guide surface 30b. A groove portion 37 for inserting the lock 7 is formed at a joint portion (base end portion) of the spring portion 32 with respect to the guide surface 30b. Further, the shaft portion 35 is divided into two by a slit 35 a extending in the insertion direction of the lock 7. Furthermore, a stepped portion 38 is formed at one end of the guide surface 30b of the main body 30 (the end in the direction in which the lock 7 is inserted) (see FIG. 10).

  On the other hand, as shown in FIGS. 14 and 15A, the lock 7 includes a plate-like main body 40 and a finger hook 41 provided at the front end of the main body 40. The thickness t of the main body 40 is set to be as large as possible within a range that can pass through the groove 37 of the push button 6. In the center of the rear end of the main body portion 40, a groove portion 42 is provided that opens in the insertion direction (in the direction of arrow A in FIGS. 10 and 16) into the lock 7 for the push button 6 so as to receive the shaft portion 35 of the push button 6. Claw portions 43a and 43b for narrowing the width of the groove portion 42 are formed on the inlet and the middle of the groove portion 42, respectively. The inside of the groove part 42 is divided into a first holding part 42a and a second holding part 42b by these claw parts 43a and 43b.

  Locking portions 44 are formed on both sides of the entrance of the groove portion 42. Further, a pair of stoppers 45 are formed on the upper surface 40a of the main body 40, and a pair of legs 46 are formed on the lower surface 40b. The amount of protrusion of the leg portion 46 from the lower surface 40b is substantially equal to the amount of protrusion of the finger rest portion 41 from the lower surface 40b. As shown in FIG. 15 (b), the stopper 45 has a wedge surface 45a extending downwardly toward the locking portion 44, a top surface 45b, and a locking surface 45c substantially orthogonal to the top surface 45b. And have.

  As shown in FIG. 16, the lock 7 is formed by pushing the main body portion 40 from the locking portion 44 side into the groove portion 37 of the push button 6 and fitting the shaft portion 35 of the push button 6 into the groove portion 42 of the lock 7. The push button 6 is attached to the push button 6 while being in close contact with the guide surface 30b of the push button 6. When the lock 7 is attached to the push button 6, the shaft portion 35 of the push button 6 gets over the claw portion 43 a formed in the groove portion 42 of the lock 7 and fits into the first holding portion 42 a. When the stopper 45 passes through the groove portion 37, the groove portion 37 gradually expands along the wedge surface 45a. When the stopper 45 exceeds the step portion 38, the groove portion 37 returns to its original width. Thereby, the lock 7 is prevented from coming off from the push button 6.

  If the lock 7 is further pushed in the insertion direction in a state where the shaft portion 35 is fitted to the first holding portion 42a, the shaft portion 35 gets over the claw portion 43b of the lock 7 and fits to the second holding portion 42b. In this manner, the lock 7 has a release position (a position indicated by a solid line in FIG. 16) where the first holding portion 42a and the shaft portion 35 are fitted along the guide surface 30b of the push button 6, and a second holding portion 42b. And a lock position (position indicated by a solid line in FIG. 10) where the shaft portion 35 is fitted.

  Although the push button 6 and the lock 7 can be resin molded products as described above, the location of the container 1 may be grasped in a dark place by mixing a phosphorescent material with at least one of the materials. If the push button 6 or the lock 7 emits light, the operation part of the container 1 can be easily identified even in a dark place. The push button 6 and the lock 7 are smaller and smaller in volume than the container body 2 and the upper lid 4, so that the amount of phosphorescent material mixed in is small, and the increase in cost due to mixing the phosphorescent material is minimized. Can do.

  In the push button 6 and the lock 7 configured as described above, the lock 7 is first attached to the push button 6, and then the support shaft 31 of the push button 6 is attached to the button mounting groove 25 of the container body 2 (FIG. 1B). And it fits in the container main body 2 in the state which can be rotated around the spindle 31 by fitting with the bearing part which is not shown in figure opening (refer FIG. 10).

  Next, the operation of the push button 6 and the lock 7 will be described. As is apparent from FIG. 10, in a state where the push button 6 is mounted in the button mounting groove 25, the spring portion 32 contacts the bottom surface 25a of the button mounting groove 25, and the repulsive force (restoration against elastic deformation) of the spring portion 32 occurs. The push button 6 is urged to rotate in the clockwise direction in FIG. Therefore, when the upper lid 4 is closed, the claw portion 33 of the push button 6 and the claw portion 4h of the upper lid 4 are engaged with each other by the force of the spring portion 32, and the upper lid 4 is held in a closed state. The position of the push button 6 at this time corresponds to the closed position.

  When the lock 7 is pushed into the lock position with the upper lid 4 closed, the leg portion 46 of the lock 7 comes into contact with the locking surface 25b (FIG. 10) of the button mounting groove 25. Therefore, it becomes impossible to push in the operation surface 30a of the push button 6, and the claw portions 33 and 4h cannot be disengaged. Moreover, in the locked position, the locking portion 44 of the lock 7 protrudes from the push button 6 and fits into the lock hole 4 j of the upper lid 4. Since the engagement depth of the locking portion 44 with respect to the lock hole 4j can be made sufficiently larger than the engagement amount between the claw portions 33 and 4h, the push button 6 or Even if the upper lid 4 is elastically deformed, the upper lid 4 can be reliably restrained to the closed position by the lock 7.

  On the other hand, when the lock 7 is pulled out from the push button 6 in the extraction direction (the direction of arrow B in FIGS. 10 and 16) and moved to the release position, the locking portion 44 comes out of the locking hole 4j and the leg portion 46 locks the locking surface. Leave 25b. Thereby, the operation surface 30a of the push button 6 is pushed down to disengage the claws 33 and 4h (this state corresponds to the open position of the push button 6), and the upper lid 4 can be opened. The push-up portion 34 of the push button 6 is engaged with the notch 4k of the upper lid 4, and the push-up portion 34 lifts the upper lid 4 when the operation surface 30 a of the push button 6 is pushed. Accordingly, even when a relatively large resistance is applied when the upper lid 4 is opened due to the wet tissue 102 biting between the closing rib 4f of the upper lid 4 and the side wall 22b of the second recess 22, the upper lid 4 is reliably opened. be able to.

  As indicated by the imaginary line in FIG. 10, when the lock 7 is pulled out from the push button 6, the locking surface 45c of the stopper 45 comes into contact with the step portion 38 of the guide surface 30b of the push button 6 to prevent the lock 7 from coming off. Is done. In order to further secure the locking of the lock 7, as indicated by an imaginary line in FIG. 14, a claw portion that protrudes obliquely toward the pull-out direction of the lock 7 on at least one side edge of the main body portion 40 of the lock 7. 47 and a concave portion 48 for receiving the claw portion 47, and when the lock 7 is inserted into the groove portion 37, the claw portion 47 is elastically deformed into the concave portion 48, and after passing through the groove portion 37, the claw portion 47 has its own restoring force. You may make it open with.

  Since the finger-hanging portion 41 of the lock 7 protrudes from the operation surface 30a, not only when the lock 7 is slid between the lock position and the release position, but also when the push button 6 is depressed to open the upper lid 4. An operation can be performed with a finger attached to the finger rest 41. When the upper lid 4 is opened, the lock 7 is pulled out to the release position and the distance from the support shaft 31 to the finger hooking portion 41 is increased. Therefore, the operation force when opening the upper lid 4 is reduced by the action of the lever.

  Since the main body portion 40 of the lock 7 is inserted into the groove portion 37 of the push button 6, the lock 7 is restrained (supported) by the push button 6 in the push-down direction of the push button 6. The lock 7 and the push button 6 rotate integrally around the support shaft 31 without leaving, and the upper lid 4 is reliably opened.

  In the container 1 with the lid described above, as shown in FIGS. 4 and 10, the upper end of the finger-hanging portion 41 protrudes from the outer surface (top surface 2 a) of the container body 2. When the package 100 is stored in the container body 2 and the container 1 is shipped as a product, a shrink film may be wound around the constricted center of the container 1. Since the shrink film is wound relatively tightly around the outer surface of the container 1 using heat shrinkage, if the lock 7 is omitted and a part of the push button 6 protrudes from the outer surface of the container body 2, The push button 6 is restrained in a state where the protruding portion of the push button 6 is pushed in by the shrink film and the spring portion 32 is somewhat bent. If such a state continues for a long time, the spring performance of the spring portion 32 deteriorates, and after removing the shrink film, the push button 6 may move even with a slight impact and the upper lid 4 may be unintentionally opened. is there. However, according to the container 1 of the present embodiment, the shrink film is wound by pushing the lock 7 into the locked position and holding the push button 6 in the closed position where the claws 33 and 4h are engaged. In this case, the push button 6 is not pushed, and there is no possibility that the spring performance of the spring portion 32 deteriorates.

  Further, since the container body 2 and the bottom lid 3 are formed in a constricted shape, if the width of the shrink film is large enough to reach the swollen portion of the container body 2, the side surfaces 2b and 2c on the front and rear sides of the container body 2 The film may be lifted from the container body 2 and the push button 6 or the lock 7 may be separated from the shrink film inward. In this case, damage due to rubbing of the contact portion between the push button 6 or the lock 7 and the shrink film can be prevented.

  The constricted shape of the container body 2 and the ring portion 14 disclosed in the above embodiment can be applied to a container with a lid from which the lock 7 is omitted. The push-up portion 34 can be provided on the lock 7 instead of the operation member. The spring portion 32 is not limited to an arcuate shape, and may be formed in a cantilever shape. The shapes of the push button 6 and the lock 7 may be appropriately changed according to the shape of the container body 2 and the like. The push button 6 and the lock 7 may be provided so that the entirety of each push button 6 and the lock 7 is retracted into the button mounting groove 25 from the outer surface (the top surface 2a, the side surface 2b) of the container body 2.

  In the above embodiment, the terms “top”, “bottom”, “side” and “top cover” are merely relative to the position of each part relative to the case where the container is installed with the outlet facing upward. The position of each part is not limited by these terms. For example, the container with a lid of the present invention may be used in a state in which the outlet is turned sideways.

  The present invention is not limited to the above embodiment, and may be implemented in various forms. For example, the contents are not limited to wet tissue. The container with a lid of the present invention is not limited to a configuration in which the contents are attached and detached by removing the bottom lid, and the attachment and detachment and refilling of the contents may be performed in an appropriate form.
