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 the container that can be easily opened can be easily opened by an infant or the like, there is a problem that the contents (for example, detergent) in the container are scattered around due to an unexpected opening by the infant.

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

In order to solve the above problems, the container according to the present invention includes a container body having a tubular mouth, and a lid made of a flexible material that is fitted and crimped on the outer peripheral side surface of the mouth. The mouth side surface recess formed in a part of the outer peripheral side surface of the mouth section and the inner peripheral side surface of the lid section are pressed to press the mouth side surface recess section to move the lid section to the mouth section. A lid side surface convex portion that is engaged with the lid side surface convex portion, and toward the predetermined gap formed between the inner peripheral side surface of the lid portion and the mouth side surface concave portion below the lid side surface convex portion. The locking is released by bending deformation of the lid portion by pressing the side surface of the lid portion .

With such a configuration, the lid is flexibly deformed by manually pressing a predetermined portion of the side surface of the lid made of a flexible material of the container in the closed state, and the lid side surface convex portion with respect to the mouth side surface concave portion is deformed. The lid can be easily opened by releasing the locking. On the other hand, for an infant with a small hand, it is difficult to release the lock by pushing a predetermined portion of the side surface of the lid with a finger to flex and deform the lid, and thus it becomes difficult to open the container.

In the container according to the present invention, the mouth portion side surface concave portion is axisymmetric with respect to the central axis of the mouth portion, consisting of a pair of groove portions formed in a predetermined horizontal direction at both positions of the outer peripheral side surface, The lid side surface convex portion may be configured to include a pair of protruding portions that are axially symmetric with respect to the central axis of the lid portion and that are formed at predetermined positions in the horizontal direction at both positions of the inner peripheral side surface. it can.

According to this structure, since the mouth side surface concave portion is the pair of central axis symmetric grooves and the lid side surface convex portion is the pair of central axis symmetrical projections, the lid side surface concave portions are respectively locked at the pair of positions with respect to the central axis. As a result, it is possible to maintain the closed state by locking, and by pressing a pair of positions on the outer peripheral side surface of the lid with a finger, the locking can be released by flexural deformation of the lid, and the lid can be easily opened. .. As described above, even if an adult who is a user can easily open the lid, a pair of positions on the outer peripheral side surface of the lid is pressed by fingers with a finger or the like to bend and deform the lid portion. It becomes difficult to open the lid.

In the container according to the present invention, a pair of notches may be formed on a side surface of the lid at a position orthogonal to the pair of protrusions with respect to the central axis of the lid.

With such a configuration, since the pair of notches are formed at the positions orthogonal to the pair of protrusions with respect to the central axis of the lid, the user is required to form the lid having the pair of protrusions. By pressing the outside of the side surface with a finger, the lid can be easily bent and deformed. This facilitates opening the lid by releasing the lock.

In the container according to the present invention, the cut portion may be formed in a triangular shape.

According to such a configuration, since the cut portion is formed in a triangular shape, when the side surface of the lid portion is pressed, it is possible to easily cause a bending deformation, and a user can easily open the lid. it can.

Embodiments of the present invention will be described below with reference to the drawings.

The configuration of the container according to the 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. .. 1A to 6B, the container 11 includes a cylindrical container body 13 having an upper end as a mouth portion 12 (see FIGS. 3 and 4B), and a lid portion 15 fitted into the mouth portion 12 and crimped. Composed.

The container body 13 has a bottom portion 13a and side surface portions 13b, 13c, 13d and 13e standing upright from the bottom portion 13a. Of these, the side surface portions 13b, 13c and 13d are bent at predetermined height positions and shoulder portions 13f are formed. The side surface portion 13e is gently connected to the shoulder portion 13f. The shoulder portion 13f is provided with a cylindrical mouth portion 12, and a lid portion 15 is fitted to close an opening 16 (see FIG. 3) at the upper end of the mouth portion 12.

The lid portion 15 is formed of a top portion 15a and a cylindrical side surface portion 15b, and the side surface portion 15b is fitted into the mouth portion 12 of the container body portion 13. The side surface portion 15b of the lid portion 15 has cut portions formed at both positions symmetrical with respect to the central axis of the lid portion 15 (the shape of the cut portion is not particularly limited, and may be, for example, a linear shape. The notch may be a notch, and is preferably a notch having a triangular shape. In the present embodiment, the notch 18a, 18b having a preferable triangle is used. The notches 18a and 18b are formed in order to easily bend and deform the lid portion 15 by pinching a predetermined position of the side surface portion 15b of the lid portion 15 made of a flexible material with a finger as described later. The cuts 18a and 18b are formed by cutting in a triangular shape from the lower end of the side surface 15b of the lid 15 to about 2/3 of the height of the side surface 15b. Further, on the outer peripheral side surface of the side surface portion 15b, a pair of surface treatment portions 19a, 19b are formed by subjecting a predetermined range including a position rotated by about 90 degrees around the central axis from the cut portions 18a, 18b. The textured surface treated portions 19a and 19b are provided for both the reason that the lid portion 15 can be easily pinched by a finger and that the position where the lid portion 15 is pinched can be specified. When the lid part 15 is fitted into the mouth part 12 of the container body part 13, the cut parts 18a and 18b are located on the side surface parts 13d and 13e side, and the surface treatment parts 19a and 19b are the side surface parts 13b and 13c side. Position. As described above, the surface treatment portions 19a and 19b are formed in a range that is a portion to which a finger is applied when the lid portion 15 is pinched by the fingers and flexibly deformed. In the case of the asymmetrical container main body 13 as in the present embodiment, the lid 15 is parallel or perpendicular to the direction in which the container main body 13 is gripped by hand (that is, the direction in which the fingers are applied to the side surface portions 13b and 13c). It is preferable to provide the notches 18a and 18b because the position where the lid 15 is sandwiched by the fingers becomes clear.

The lid portion 15 made of a flexible material is radially expanded by the mouth portion 12 of the container body 13 when the lid is closed, and is fitted into the mouth portion 12 to be in a crimped state. At this time, the side surface of the lid portion 15 is different from the pair of groove portions 21a and 21b, which are mouth side surface concave portions formed respectively in a part (a part in the circumferential direction) of the outer peripheral side surface of the side surface portion 12a of the mouth portion 12. A pair of protrusions 22a, 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 15 fitted into the mouth 12 by pressing the upper portions of the protrusions 22a and 22b into the upper inclined portions (described later) inside the grooves 21a and 21b is arranged in the arrangement described below. The structure keeps the horizontal rotation and the vertical (height) movement 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 13, and the groove portion 21b is provided on the side surface portion 13c side. It is formed at a position symmetrical with respect to the central axis. Each of the groove portions 21a and 21b is a horizontally long rectangular groove, and has an inclined shape (inclined portion) such that the upper side and the lower side inside the groove are expanded outward (see FIGS. 3 and 4B). ). Each of the groove portions 21a and 21b has a lateral (circumferential) length of about 1/8 to 1/6 of the circumferential length of the side surface portion 12a of the mouth portion 12, and 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 protrusions 22a and 22b on the inner peripheral side surface of the side surface portion 15b of the lid portion 15 are formed at positions symmetrical with respect to the central axis of the lid portion 15. The length of the protrusions 22a and 22b in the lateral direction (circumferential direction) is substantially the same as or slightly smaller than the length of the groove portions 21a and 21b in the lateral direction (circumferential direction), 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 FIG. 6A and FIG. 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 are formed on the outer peripheral side surface 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 lid portion 15 is prevented from rotating in the circumferential direction.

As shown in FIG. 3, when the lid portion 15 is in a closed state with respect to the mouth portion 12, the protrusions 22a and 22b press the lower surface of the inclined portion on the upper side of the groove portions 21a and 21b, and The upper end of the side surface portion 12a of 12 comes into contact with the inner side surface of the top portion 15a of the lid portion 15, whereby movement of the lid portion 15 in the height direction (center axis method) is prevented. In addition, in the middle portion of the side surface portion 15b of the lid portion 15, there is a space forming a predetermined gap between the side surface portion 15b and 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 designated. When pressed by, 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 abuts on the lower inclined portion of the groove portions 21a and 21b, whereby the lid portion 15 is closed. A force to raise and slide is generated.

Next, the materials of the lid portion 15 and the container body portion 13 forming the container 11 will be described. The lid 15 made of a flexible material is manufactured by a known method such as compression molding or injection molding of 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, silicone resin, etc. are used. The lid 15 is preferably manufactured by injection molding using polyethylene.

The container body 13 can be manufactured by a known method. For example, the above-mentioned thermoplastic resin is extruded into a pipe shape, one end of which is pinched off to form a parison, and compressed air is blown into this parison to form a bottle-shaped container, by 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, but an olefin resin or a polyester resin such as polyethylene terephthalate can be used. Examples of the olefin resin include polymers of various olefins 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-based copolymers such as olefin resins graft-modified with ethylenically unsaturated carboxylic acid or its anhydride, and blends thereof are used, but particularly preferred The thing is high density polyethylene. Further, it may be formed of a plurality of layers, for example, a gas barrier resin layer made of ethylene-vinyl alcohol copolymer or the like is formed between inner and outer surface layers of an olefin resin via an adhesive layer as appropriate. Good. Further, it may have a structure in which a polyester resin layer such as polyethylene terephthalate is laminated on the outer surface of the olefin resin layer via an adhesive layer. The container body 13 is particularly preferably manufactured by direct blow molding of high-density polyethylene.

Next, the lid opening operation of the container 11 will be described with reference to FIGS. 7A to 7C. As shown in FIG. 7A, the lid portion 15 made of a flexible material is fitted in the mouth portion 12 of the container body 13 and is in a closed lid state in which the mouth portion is crimped. As described above, when the container 11 is in the closed state, the protrusions 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 formed groove portions 21a and 21b are locked in a pressed state, movement of the lid portion 15 fitted in the mouth portion 12 in the height direction (removal direction) is prevented by opening the lid portion. Therefore, in order to perform the lid opening operation, it is necessary to bend and deform the lid portion 15 in the procedure described below to release the engagement 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 by the thumb 31 and the index finger 32, and a force is applied to the mouth portion 12 side so as to bend and deform the lid portion. 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 protrusions 22a and 22b formed on the inner peripheral side surface thereof, and have a predetermined gap between the surface treatment portions 19a and 19b and the groove portions 21a and 21b. Are formed.

As shown in FIG. 7B, when the surface treatment portions 19a and 19b on the side surface portion 15b are sandwiched inward by 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 surface portion 15b of the open portion is pushed toward a space serving as a gap between the groove portions 21a and 21b, the lower end of the side surface portion 15b abuts on the lower inclined portion of the groove portions 21a and 21b, and the lid portion 15 is slid up. The force to move 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 (arrow 35 direction). At this time, since the triangular cutouts 18a and 18b are formed on the side surface portion 15b of the lid portion 15 at positions rotated by 90 degrees with respect to the projecting portions 22a and 22b, the bending of the lid portion 15 described above is performed. Deformation can be easily performed.

As shown in FIG. 7C, when the protruding portions 22a and 22b that press and slide the inclined portions of the groove portions 21a and 21b come out of the groove portions 21a and 21b, the locking with the groove portions 21a and 21b is released. Thus, the lid 15 can be moved outward, that is, the lid can be opened. After the lock is released, the pressing of the thumb 31 and the forefinger 32 against the side surface portion 15b for bending deformation becomes unnecessary, and the lid portion 15 is lifted as it is in the direction of the arrow 35 to complete the lid opening.

As described above, when the lid is closed, the lid portion 15 is fitted into the mouth portion 12 and crimped, and the protrusions 22a and 22b of the lid portion 15 are engaged with the groove portions 21a and 21b of the mouth portion 12, so that the lid portion 15 is opened. Since the lid is blocked, unnecessary opening of the lid by an infant or the like can be blocked. Then, of 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 inward, the side surface portion 15b causes the groove portion 21a. , 21b are pushed into the gap formed between the two and 21b, and are flexibly deformed. By this flexural deformation, the projecting portions 22a and 22b rise up from the groove portions 21a and 21b and the locking is released, so that the user can easily open the lid. On the other hand, it is difficult for an infant with a small hand to release the lock by pinching the pair of surface treatment portions 19a and 19b with the thumb 31 and the forefinger 32 and pushing the inside to bend and deform it. It is possible to prevent an accidental opening of the lid due to the above, and to prevent scattering of the contents in the container 11.
