  According to the container described in Patent Document 1, since the lid can be easily opened by pressing the side surface of the lid, the container is convenient for the user. Since a container that can be easily opened can be easily opened by an infant or the like, there arises a problem that an unexpectedly opened lid by the infant spreads the contents (for example, detergent) in the container around the container.

  An object of the present invention is to provide a container having a structure that makes it easy for a user to open the container, but makes it difficult for an infant or the like to open the container.

  In order to solve the above-described problems, a container according to the present invention includes a container main body having a cylindrical mouth, and a lid made of a flexible material that is fitted into the outer peripheral side surface of the mouth and is crimped. A mouth side recess formed on a part of the outer peripheral side of the mouth and an inner peripheral side of the lid, pressing the mouth side recess to remove the lid from the mouth And a lid side surface convex portion that releases the locking by bending deformation of the lid portion.

  According to such a configuration, the lid portion is bent and deformed by manually pressing a predetermined portion of the side surface of the lid portion made of a flexible material of the container in the closed state, and the lid side surface convex portion is formed with respect to the mouth side surface concave portion. The lid can be easily opened by releasing the lock. On the other hand, it is difficult for an infant with a small hand to unlock the container by pushing a predetermined part of the side of the lid with a finger to bend and deform it, and it is difficult to open the container.

  In the container according to the present invention, the mouth side recess is made up of a pair of groove portions that are axisymmetric with respect to the center axis of the mouth, and are formed at predetermined positions in the horizontal direction at both positions of the outer peripheral side surface. The lid side surface convex portion may be configured by a pair of projecting portions that are axially symmetric with respect to the central axis of the lid portion and are formed at predetermined positions in the horizontal direction at both positions on the inner side surface. .

  According to such a configuration, the mouth side recesses are a pair of grooves that are symmetrical with respect to the center axis, and the side protrusions of the lid portion are a pair of protrusions that are symmetrical with respect to the center axis. As a result, the closed state by the locking can be maintained, and the pair of positions on the outer peripheral side surface of the lid can be pressed with a finger, so that the locking can be released by the bending deformation of the lid, and the opening of the lid is facilitated. . As described above, even if the user can easily open the lid, a pair of positions on the outer peripheral side surface of the lid described above is pressed with a finger against an infant with a small hand, etc., and the lid portion is bent and deformed. It becomes difficult to open the lid.

  The container which concerns on this invention WHEREIN: The side surface of the said cover part can be set as the structure by which a pair of notch part is formed in the position orthogonal to a pair of said protrusion part with respect to the said central axis of the said cover part.

  According to such a configuration, since the pair of cut portions are formed at positions orthogonal to the pair of projecting portions with respect to the central axis of the lid portion, the user can form the lid portion on which the pair of projecting portions are formed. The lid can be easily bent and deformed by pressing the outside of the side surface with a finger. This facilitates opening the lid by releasing the lock.

  The container which concerns on this invention WHEREIN: The said notch part can be set as the structure formed in a triangle shape.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  A configuration of a container according to an embodiment of the present invention will be described with reference to FIGS. 1A, 1B, 2A, 2B, 3, 4A, 4B, 5A to 5C, 6A, and 6B. . In FIG. 1A to FIG. 6B, the container 11 is composed of a cylindrical container main body portion 13 having an upper end as a mouth portion 12 (see FIGS. 3 and 4B), and a lid portion 15 that is fitted into the mouth portion 12 and is crimped. Composed.

  The container body 13 has a bottom portion 13a and side portions 13b, 13c, 13d, and 13e erected from the bottom portion 13a. Of these, the side portions 13b, 13c, and 13d are each bent at a predetermined height, and a shoulder portion 13f. And the side surface portion 13e gently connects to the shoulder portion 13f. A cylindrical mouth portion 12 is provided in the shoulder portion 13f, and a lid portion 15 is fitted to close the opening 16 (see FIG. 3) at the upper end of the mouth portion 12.

  The lid portion 15 is formed by a top portion 15 a and a cylindrical side surface portion 15 b, and the side surface portion 15 b is fitted into the mouth portion 12 of the container main body portion 13. The side surface portion 15b of the lid portion 15 is formed with cut portions at both positions that are symmetrical with respect to the central axis of the lid portion 15 (the shape of the cut portion is not particularly limited, for example, linear (This is preferably a triangular cut portion. In this embodiment, the cut portions 18a and 18b are preferably triangular.) The notches 18a and 18b are formed so that a predetermined position of the side surface portion 15b of the lid portion 15 made of a flexible material is sandwiched between fingers and the lid portion 15 is easily bent and deformed as will be described later. The cut portions 18a and 18b are formed by cutting in a triangular shape from the lower end of the side surface portion 15b of the lid portion 15 to about two-thirds of the height of the side surface portion 15b. Further, a pair of surface treatment portions 19a and 19b are formed on the outer peripheral side surface of the side surface portion 15b. The pair of surface treatment portions 19a and 19b are formed by embossing a predetermined range including a position rotated approximately 90 degrees around the center axis from the cut portions 18a and 18b. The surface treatment parts 19a and 19b subjected to the texture processing are provided for both the reason that the lid part 15 is easily pinched by the finger and the reason for specifying the position to be pinched by the finger. When the lid portion 15 is fitted into the mouth portion 12 of the container body portion 13, the cut portions 18a and 18b are positioned on the side surface portions 13d and 13e, and the surface treatment portions 19a and 19b are on the side surface portions 13b and 13c side. It becomes the position. As described above, the surface treatment portions 19a and 19b are formed in a range to be a portion to which a finger is applied when the lid portion 15 is bent and deformed with the finger. In the case of the non-target container main body 13 as in the present embodiment, the lid 15 is parallel to or perpendicular to the direction in which the container main body 13 is grasped by hand (that is, the direction in which fingers are applied to the side surfaces 13b and 13c). If the cut portions 18a and 18b are provided, the position where the lid portion 15 is sandwiched between fingers becomes clear, which is preferable.

  The lid portion 15 made of a flexible material is spread in the radial direction by the mouth portion 12 of the container main body portion 13 when the lid is closed, and is fitted into the mouth portion 12 and is crimped. At this time, the side surface of the lid portion 15 is opposed to the pair of groove portions 21a and 21b which are concave portions on the side surface of the mouth portion formed on a part of the outer peripheral side surface of the side surface portion 12a of the mouth portion 12 (a part in the circumferential direction). The pair of protrusions 22a and 22b, which are lid side surface convex portions formed on the inner peripheral side surface of the portion 15b, are fitted and locked so as to be pressed. Specifically, the lid portion 15 in which the upper portions of the protruding portions 22a and 22b are pressed into the upper inclined portions (described later) inside the groove portions 21a and 21b and fitted into the mouth portion 12 is disposed as described later. The structure keeps the horizontal rotation and the movement in the vertical direction (height direction) restricted.

  Of the pair of groove portions 21a and 21b on the outer peripheral side surface of the side surface portion 12a of the mouth portion 12, the groove portion 21a is provided on the side surface portion 13b side of the container body portion 13, and the groove portion 21b is provided on the side surface portion 13c side. It is formed at a position that is symmetric with respect to the central axis. The groove portions 21a and 21b are horizontally long rectangular grooves, and have a shape (inclined portion) that is inclined so that the upper side and the lower side inside the groove expand outward (see FIGS. 3 and 4B). ). The groove portions 21a and 21b each have a lateral length (circumferential direction) length of about 1/8 to 1/6 of the circumferential length of the side surface portion 12a of the mouth portion 12, and have a length in the height direction. It is formed to be about 2/3 to 3/4 of the height of the side surface portion 12a.

  The pair of protruding portions 22 a and 22 b on the inner peripheral side surface of the side surface portion 15 b of the lid portion 15 are formed at positions that are symmetric with respect to the central axis of the lid portion 15. The length in the lateral direction (circumferential direction) of the projecting portions 22a and 22b is substantially the same as or slightly smaller than the length in the lateral direction (circumferential direction) of the groove portions 21a and 21b, and the length in the height direction is the groove portion 21a. , 21b is about one fifth of the length in the height direction. As shown in FIGS. 6A and 6B, the pair of protrusions 22 a and 22 b formed on the inner peripheral surface of the side surface portion 15 b of the lid portion 15 is a pair of outer peripheral side surfaces of the side surface portion 12 a of the mouth portion 12. Since the groove portions 21a and 21b are in close contact with each other in the circumferential direction, the circumferential rotation of the lid portion 15 is prevented.

  As shown in FIG. 3, when the lid portion 15 is closed with respect to the mouth portion 12, the projecting portions 22a and 22b press the lower surface of the inclined portion on the upper side of the groove portions 21a and 21b, and the mouth portion. The upper ends of the twelve side surface portions 12 a are in contact with the inner surface of the top portion 15 a of the lid portion 15, thereby preventing the lid portion 15 from moving in the height direction (center axis method). In addition, in the intermediate portion of the side surface portion 15b of the lid portion 15, there is a space that becomes a predetermined gap between the groove portions 21a and 21b, and the surface treatment portions 19a and 19b formed on the outer peripheral side of the side surface portion 15b are pointed to. When the pressure is pressed, the pressed side surface portion 15b can be inserted into the gap. The pressed side surface portion 15b is pushed toward a space serving as a gap between the groove portions 21a and 21b, and the lower end of the side surface portion 15b hits the inclined portion on the lower side of the groove portions 21a and 21b, thereby causing the lid portion 15 to be moved. Ascending and sliding force is generated.

  Next, the material of the cover part 15 and the container main body part 13 which comprise the above-mentioned container 11 is demonstrated. The lid portion 15 made of a flexible material is manufactured by a known method such as compression molding or injection molding of a thermoplastic resin. Examples of the thermoplastic resin include olefins such as polyethylene, polypropylene, ethylene-propylene copolymer, polybutene-1, ethylene-butene-1 copolymer, propylene-butene-1 copolymer, and ethylene-vinyl acetate copolymer. Resin, polystyrene, styrene-butadiene copolymer, silicon resin and the like are used. The lid 15 is preferably manufactured by injection molding using polyethylene.

  The container main body 13 can be manufactured by a known method. For example, by extruding the above-mentioned thermoplastic resin into a pipe shape, pinching off one of its tip portions to form a parison, and blowing this compressed air into the parison to form a bottle-like container, so-called direct blow molding Manufactured. The thermoplastic resin forming the bottle-shaped container is not particularly limited as long as it can be molded into a bottle shape, but an olefin resin or a polyester resin such as polyethylene terephthalate can be used. Examples of the olefin resin include various olefin polymers such as low density polyethylene, linear low density polyethylene, medium density polyethylene, high density polyethylene, and polypropylene, and copolymers of various olefins such as propylene-ethylene copolymer. , Ethylene-vinyl acetate copolymers, modified olefin copolymers such as olefin resins graft-modified with ethylenically unsaturated carboxylic acids or anhydrides thereof, and blends thereof are particularly suitable. The thing is high density polyethylene. Moreover, it may be formed from a plurality of layers. For example, a gas barrier resin layer made of an ethylene-vinyl alcohol copolymer or the like is appropriately formed between the inner and outer surface layers of the olefin resin via an adhesive layer. Also good. Moreover, you may have a structure where polyester resin layers, such as a polyethylene terephthalate, were laminated | stacked on the outer surface of the olefin resin layer through the adhesive bond layer. The container body 13 is particularly preferably manufactured by direct blow molding of high density polyethylene.

  Next, the opening operation of the container 11 will be described with reference to FIGS. 7A to 7C. As shown to FIG. 7A, the cover part 15 which consists of a flexible material is engage | inserted by the mouth part 12 of the container main-body part 13, and is in the closed cover state which crimped | bonded the mouth part. As described above, when the container 11 is in the closed state, the protruding portions 22a and 22b formed on the inner peripheral side surface of the side surface portion 15b of the lid portion 15 are formed on the outer peripheral side surface of the side surface portion 12a of the mouth portion 12. Since the groove portions 21a and 21b are locked in a pressed state, the lid portion 15 fitted in the mouth portion 12 is prevented from moving in the height direction (removing direction). Therefore, in order to perform the lid opening operation, it is necessary to bend and deform the lid portion 15 according to the procedure described below to release the locking between the protruding portions 22a and 22b and the groove portions 21a and 21b.

  The surface treatment portions 19a and 19b of the side surface portion 15b of the lid portion 15 are sandwiched between the thumb 31 and the index finger 32, and a force is applied to the extent that the lid portion is bent and deformed toward the mouth portion 12 side. The surface treatment portions 19a and 19b formed on the outer peripheral side surface of the side surface portion 15b correspond to the lower positions of the projecting portions 22a and 22b formed on the inner peripheral side surface, and have a predetermined gap between the groove portions 21a and 21b. Is formed.

  As shown in FIG. 7B, when the surface treatment portions 19a and 19b on the side surface portion 15b are sandwiched between the thumb 31 and the index finger 32 (in the directions of arrows 33a and 33b), the surface treatment portions 19a and 19b are formed. The side portion 15b of the portion is pushed toward the space that forms a gap between the groove portions 21a and 21b, the lower end of the side portion 15b hits the inclined portion on the lower side of the groove portions 21a and 21b, and the lid portion 15 is raised and slid. A moving force is generated. When the lid portion 15 is further bent and deformed by being sandwiched between the thumb 31 and the index finger 32, the protruding portions 22a and 22b slide upward while pressing the inclined portions on the upper side of the groove portions 21a and 21b (in the direction of arrow 35). At this time, since the triangular cut portions 18a and 18b are formed on the side surface portion 15b of the lid portion 15 at positions rotated 90 degrees with respect to the projecting portions 22a and 22b, the bending of the lid portion 15 described above is formed. The deformation can be easily performed.

  As shown in FIG. 7C, when the projecting portions 22a and 22b, which are pushed up and slid by the inclined portions of the groove portions 21a and 21b, go out of the groove portions 21a and 21b, the engagement with the groove portions 21a and 21b is released. Thus, the lid portion 15 can be moved outward, that is, the lid can be opened. After the lock is released, pressing for deforming and deforming the side surface portion 15b by the thumb 31 and the index finger 32 becomes unnecessary, and the lid portion 15 is lifted in the direction of the arrow 35 to complete the lid opening.

  As described above, when the cover is in the closed state, the lid 15 is fitted into the mouth 12 and crimped, and the protrusions 22a and 22b of the lid 15 are engaged with the grooves 21a and 21b of the mouth 12 so that the lid 15 is opened. Since the lid is blocked, unnecessary opening by an infant or the like can be blocked. And among the outer peripheral side surfaces of the side surface portion 15b of the lid portion 15, when the surface treatment portions 19a and 19b provided on the lower side of the projecting portions 22a and 22b are sandwiched with fingers and pressed toward the inside, the side surface portion 15b becomes the groove portion 21a. , 21b, and is deformed by bending into the gap formed between them. Due to this bending deformation, the protruding portions 22a and 22b rise from the groove portions 21a and 21b, and the locking is released, so that the user can easily open the container 11. On the other hand, it is difficult for an infant with a small hand or the like to release the lock by sandwiching the pair of surface treatment parts 19a and 19b between the thumb 31 and the index finger 32 and pushing them inward to bend and deform. Inadvertent opening due to can be prevented, and scattering of the contents in the container 11 can be prevented.
