Abstract
If the diameter of an opening side neck portion is decreased to
minimize the contact surface between contents and air and a small
cap is fitted on a container where there is the concern that
exposure to air may alter the quality of contents in the container,
there is not only the problem that a gap results between the cap
top board and the container opening where adequate locking force is
not available but the problem that force is required to open and
close the lid, making removal and fitting troublesome. A container
made so a large cap can be fitted thereto by providing a cap
locking neck portion 30 whose inner and outer diameters are larger
than an opening side neck portion 13 at a container should side
neck portion 14 of a container neck 10.

BEST MODE FOR CARRYING OUT THE INVENTION
[0051] The present invention is described below using embodiments
illustrated below.
Embodiment 1
[0052] For the embodiment shown in FIGS. 1 through 5, a container 1
according to the present invention has a construction provided with
a cap locking neck portion 30 larger than both the inner and outer
diameters of an opening side neck portion 13 at a container
shoulder side neck portion 14 of a container neck 10, thereby
providing the effect that an easily gripped large cap can be used
and a powerful cap locking force is obtained by means of a wide cap
locking neck 30 as well as the effect that a large amount of
content can be stored within the neck.
[0053] In addition, the present invention has a construction
wherein an extrusion flexibility is furnished to the cap locking
neck portion 30, thereby providing the effect that a large amount
of content can be stored in the neck and extracted for use.
[0054] In addition, the present invention has a construction
wherein an extrusion restorative flexibility is furnished to the
cap locking neck portion 30, thereby providing the effect that a
large amount of content can be stored in the neck and extruded as
well as that a cap can be immediately replaced because of the
immediate restoration resulting from the restorative flexibility
subsequent to extrusion.
Embodiment 2
[0055] For the illustrated embodiment, the above-mentioned cap
locking neck portion 30 is provided at the container shoulder side
neck portion 14 constructed with a larger diameter than the opening
side neck portion 13 of the container neck 10.
[0056] The wider the outer diameter of the thick neck portion in
comparison to the outer diameter of the thin neck portion, the
larger the cap locking neck portion 30 that can be used, and the
larger the locking effect that can be expected.
[0057] It is appropriate that the outer diameter of the thick neck
portion be at least roughly 1.2 times larger than the outer
diameter of the thin neck portion, with somewhere between 1.6 and
2.4 times larger preferable for ordinary caps, although the factor
can be either smaller or larger for special containers and/or
caps.
[0058] For the illustrated embodiment, the cap locking neck portion
30 comprises a screw closing construction and is provided with four
large-pitch male threads 31 at intervals of 90 degrees or less such
that they do not overlap, such that the cap can be completely
mounted with a rotation of substantially 90 degrees or less.
Although omitted from the drawings, the cap is provided with four
female threads for threading on the male threads 31, for a
construction that enables the cap to be screwed and mounted with a
sensation approximating a single movement.
[0059] According to the embodiment, when the male thread 31
comprises a flexible elastic body, the constitution is such that
simply pressing the cap will advance the female threads of the cap
over the male threads 31 for a fitted engagement, subsequent to
which the cap may be firmly tightened simply by applying a
rotational force in the threading direction.
Embodiment 3
[0060] In addition, the cap locking neck portion 30 of the
container neck 10 is provided with a stopper 32 to prevent reverse
rotation, and is constructed such that fixing of the mounted cap is
secured by means of the stopper 32.
[0061] For the illustrated embodiment, the stopper 32 is placed in
four locations at 90 degree intervals on a border portion 23 away
from the above-mentioned opening side neck portion 13, and is
constructed such that when a stopper on the cap side omitted in the
drawings crosses the stopper 32 when the mounting completes, they
engage, checking reverse rotation of the cap.
[0062] In addition, for the embodiment of the present invention,
the stopper 32 is constructed such as to engage with a flexible
deformation, engaging with a click stop due to the flexible
release, enabling the cap to be fixed with a click sensation.
Embodiment 4
[0063] In addition, for other embodiments not illustrated, the cap
locking neck portion 30 comprises a press locking construction,
provided with a locking level 33 between the cap locking neck
portion 30 and the container shoulder side neck portion 14,
enabling a construction wherein mounting of the cap completes when
the locking projection provided in the cap skirt portion engaged
the locking level 33 due to pressing. Therefore, a construction is
possible wherein the locking level 33 on the container side and the
locking projection are constructed from a flexible, elastic body,
the cap is mounted by a pressing operation with a click-stop
method, and the cap comes off when the locking projection of the
cap exceeds the locking level portion 33 when the cap is simply
tugged after using the container.
[0064] In addition, for the embodiment of the present invention, a
parison of a plastic tube corresponding to the entire container,
including the cap locking neck portion 30 of the container, is
introduced into an external mold, which is then closed, sandwiching
the bottom therein, and through a conventionally known hollow
molding process for feeding compressed air from the neck opening 12
side, a container of nearly uniform thickness is formed, making it
possible to easily mold a container from hollow molding of plastic.
In addition, for the embodiment of the present invention, a
container has a construction comprising a squeeze container,
enabling not only a large of amount of content to be filled into
the container up to the thick neck 14 of the container opening 12,
but enabling sealing with the thick cap locking neck portion in
which content is stuck so that air is checked from flowing into the
container even when the squeezed container body attempts to restore
itself.
Embodiment 5
[0065] In addition, according to the embodiment shown in FIGS. 1
through 5, a container body 1 according to the present invention
has a construction wherein a cap adhesion elastic structure 20 is
provided at the border portion between the opening side neck
portion 13 of the neck 10 and the cap locking neck portion 30.
[0066] The cap adhesion elastic structure 20 has a structure that
maintains cap adhesion elasticity when a force is applied in the
vertical direction on the neck 10 to which the cap is attached,
enabling compression in the vertical direction.
[0067] Consequently, the neck opening 12 can be reliably sealed by
means of the cap adhesion elasticity when the board-shaped lid body
pressure joins the neck opening top surface 11 of the container
body 1.
[0068] As a result, the gap between the cap top board portion and
the neck portion opening board surface 11 arising because there is
no longer any thickness in the sealing material or the inner
stopper elastically deforms and disappears along with compression
of the cap adhesion elastic structure 20, and the sealability due
to the cap is maintained even when the user replaces the cap after
removing an inner stopper and/or sealing material from container 1,
having the inner stopper and/or the sealing material, purchased by
the user.
[0069] In particular, for constructions wherein the cap is mounted
by simply pressing without rotation and constructions wherein
mounting is with a minute rotation, a sealing strength for the
container opening is obtained from the adequate mounting strength
of the cap adhesion elastic structure 20, liquid leaking and the
like are prevented, and use is possible free of worry .
[0070] In addition, the present invention has a construction
wherein a cap adhesion elastic structure 20 is provided between the
opening top surface 11 of the container neck 10 and the cap locking
neck portion 30, the cap top board portion thereby contacts the
opening top surface 11, locking the cap, and sealability of the cap
is obtained from the elasticity of the cap adhesion elastic
structure 20 between the container neck 10 and the cap locking neck
portion 30.
Embodiment 6
[0071] In another embodiment of the present invention, it is
possible to reliably carry out the application of a sealing
material from above the cap by means of heat sealing during the
manufacture of the container in which the sealing material has been
applied to the container opening top surface 11 because the cap top
board adheres to the sealing material on the opening top surface 11
due to cap adhesion elasticity when the sealing material contacts
the opening top surface 11 of the container body 1, and the sealing
material adheres to the top board portion, fitting over the
cap.
Embodiment 7
[0072] In addition, for the next illustrated embodiment, the cap
adhesion elastic structure 20 in the container body 1 of the
present invention has a construction comprising, in order from the
opening side going outward, a small concave cross-section portion
21 projecting in a peak form, a large concave cross-section portion
22, and a border portion 23 either flat-surfaced or gently
sloping.
[0073] In addition, this cap adhesion elastic structure 20
comprises, in order from the opening going inward, a small concave
cross-section portion 24 projecting in a trough form, and a large
concave cross-section portion 25. The cross-section portion 24
comprises the lower piece portion of the cross-section portion 21
and the upper piece portion of the cross-section portion 22, and
the cross-section portion 25 comprises the lower piece portion of
the cross-section portion 22 and the border portion 23.
[0074] Furthermore, trough-shaped concave cross-sections 24 and 25
of the cap adhesion elastic structure 20 are provided with an inner
diameter at least as large as the opening 12, and because the cap
adhesion elastic structure 20 therefore does not add a squeezing
structure more narrow than the container opening 12 at the
container neck 10, the inner contents can be smoothly extracted,
and inspection of the adhesive state of the seal material for the
container internal opening 12 from the bottom of the container body
can made easy at the time of manufacture.
[0075] For the illustrated embodiment, the substantial cap adhesion
elasticity of the cap adhesion elastic structure 20 is borne mainly
by the elasticity of the large concave-shaped cross-section 22 in a
peak form, whereas the small concave cross-section 21 contacts the
inner cylinder portion of the cap covering the neck 10 to mainly
function to support the sealability with the opening top surface 11
of the cap top board portion, and the border portion 23 functions
mainly as a border portion for connecting the cross section 22 of
the cap adhesion elastic structure 20 and the cap locking neck
portion 30.
Embodiment 8
[0076] Consequently, an embodiment wherein the cap adhesion elastic
structure 20 has one concave cross-section portion 21 or 22 rather
than two continuous cross-section portions as in the embodiment is
fine, in which case, the border portion 23 is also unneeded. As the
cap adhesion elastic structures 20, the concave cross-section
portions 21, 22, 24 and 25 all have a construction for maintaining
cap adhesion elasticity in the vertical direction, deforming and
shrinking slightly for elastic restoration, completely different
from the folding bellows structure.
Embodiment 9
[0077] For the embodiment described in FIG. 6 and FIG. 7, the
adhesion elastic structure 20 has a construction wherein three
outwardly projecting small concave cross-sections 21 and one large
concave cross-section 22 as well as three inwardly projecting small
concave cross-sections 24 and one large concave cross-section 25
are provided, connecting to the cap locking portion 30 on the thick
neck through the border portion 23, and as the adhesion elastic
structure 20, the concave cross-sections 21, 22, 24 and 25 all
maintain upright elasticity in the vertical direction, deforming
and shrinking for elastic restoration.
Embodiment 10
[0078] For the embodiment described in FIG. 8 and FIG. 9, the
adhesion elastic structure 20 has a construction wherein two
outwardly projecting small concave cross-sections 21 and three
large concave cross-sections 22 as well as two inwardly projecting
small concave cross-sections 24 and three large concave
cross-sections 25 are provided, connecting to the cap locking
portion 30 on the thick neck through the border portion 23, and as
the adhesion elastic structure 20, the concave cross-sections 21,
22, 24 and 25 all maintain upright elasticity in the vertical
direction, deforming and shrinking for elastic restoration.
Embodiment 11
[0079] For the embodiment described in FIG. 10 and FIG. 11, the
adhesion elastic structure 20 has a construction wherein one
outwardly projecting small concave cross-section 21 and two large
concave cross-sections 22 as well as one inwardly projecting small
concave cross-section 24 and two large concave cross-sections 25
are provided, connecting to the cap locking portion 30 on the thick
neck through the border portion 23, and as the adhesion elastic
structure 20, the concave cross-sections 21, 22, 24 and 25 all
maintain upright elasticity in the vertical direction, deforming
and shrinking for elastic restoration.
Embodiment 12
[0080] For the embodiment described in FIG. 12 and FIG. 13, the
adhesion elastic structure 20 has a construction wherein two
outwardly projecting small concave cross-sections 21 and two large
concave cross-sections 22 as well as two inwardly projecting small
concave cross-sections 24 and two large concave cross-sections 25
are provided, connecting to the cap locking portion 30 on the thick
neck through the border portion 23, and as the adhesion elastic
structure 20, the concave cross-sections 21, 22, 24 and 25 all
maintain upright elasticity in the vertical direction, deforming
and shrinking for elastic restoration.
Embodiment 13
[0081] In addition, the adhesion elastic structure 20 may be used
in an embodiment without any of the concave cross-sections 21, 22,
24 or 25 provided as in the above-mentioned embodiments, using
instead only a border portion 23 with a flat or gradually sloping
surface connecting the small diameter opening side neck portion 13
and the large diameter container shoulder side neck portion 14. In
the case of gradually sloping surfaces, with dish-shaped sloping
surfaces, for example, the elastic deformation strength can be set
stronger for downward slopes than it is for horizontal surfaces as
illustrated, and the elastic deformation strength can be set weaker
in the case of upward slopes than for horizontal surfaces.
[0082] For the illustrated embodiment, the use of hollow molding of
plastic molds a thicker container shoulder side neck portion 14 in
comparison to the nearly uniform thickness of the opening side neck
portion 13 of the container neck 10 for a structure that provides
the connection frame portion with an adhesion elastic structure 20.
Consequently, the concave cross-sections 21, 22, 24 and 25 and the
border portion 23 composing the adhesion elastic structure 20 in
the above-mentioned embodiments compose the connecting frame
portion according to the present invention.
Embodiment 14
[0083] FIGS. 14 through 16 show an embodiment of the cap 40,
produced as one piece by injection molding of comparatively hard
plastic, in which 48 engaging teeth 42 are provided inside the
skirt portion 41. 43 is a female thread in 4 positions capable of
threading at a substantially 90.degree. angle and provided directly
above the engaging teeth 42, 44 is the top board portion, and 45 is
the cap portion opening downward within the neck, provided from the
center of the top board portion 44 to directly above the female
threads 43 in four cylindrical positions concentric with the skirt
portion 41.
[0084] The neck-internal cap 45 is provided with an upper cylinder
48 for covering the upper half portion of the thin-neck container
neck 10 and a lower cylinder 49 in which notches 46 are provided
relative to concave cross-section portions 21 and 22 with a
somewhat thick neck shape, and is constituted such that the locking
piece 47 provided inside the bottom edge of the lower cylinder 49
fits elastically into the large diameter concave cross-section
portion 22 of the container 1 by means of the notches 46
accompanying an elastic click sensation.
Embodiment 15
[0085] FIGS. 17 through 20 show an embodiment of the tube container
1, a squeeze tube container produced by blow molding of
comparatively soft plastic and provided with 9 integrated locking
teeth 34 at equal intervals on the container shoulder portion 35.
31 is male threads at four locations on the thick neck portion,
provided to thread the female threads 43 in four locations on the
cap 40. 13 is a thin-neck opening side neck, and concave
cross-sections 21 and 22 capable of elastic deformation in the
vertical direction are provided between the opening side neck
portion 13 and female threads 31 in four locations such as to
contact the top board portion 44 when the cap is being mounted and
pressure attach to the opening portion 11. The cap portion 45
inside the neck of the cap 40 is provided to fit onto the opening
side neck 13, including the bellows-shaped portions 21 and 22. It
is preferable that the tube container 1 is formed by a transparent
plastic material allowing the contents to be seen. If it holds
contents up to the swell-neck portion provided with the four female
threads 31, the contents can be squeezed out by pressing up to the
swell-neck during use.
[0086] FIG. 20 is an enlarged schematic view of the essential
portion showing the state of engagement of the engaging teeth 42 of
the cap 40 and the locking teeth 34 of the container 1.
