CA 02909818 2015-10-19
The invention relates to a container, in particular a plastic vial produced in
blow-molding method and filled and closed in the mold, comprising a neck part
adjoining a container body, onto which a one-part or multi-part cap can be
placed, in particular slipped, wherein a fixing part is allocated to the cap,
connected to the cap by means of at least one predetermined breaking point,
which can be detached by a relative rotational motion between the cap and the
container body or parts thereof.
From DE 42 32 305 Cl a multi-part cap for containers is known, in particular
bottles produced in the blow-molding method and filled and closed in the mold,
including in the form of a vial, having a neck part, onto which the cap can be
placed, whereby, adjoining to the section receiving the neck part, the cap has
integrally formed part that is formed as a dropper. The above-mentioned patent
describes, as further known solutions, bottles of this kind having an
threaded neck that is closed at its free end by a closure part, integrally
with the neck part, wherein a cap screwed onto the neck part is provided with
centrally arranged spike on the inside as an opening device with which the
closure part can be pierced. When the cap is removed after piercing the
part, the liquid present in the bottle can be discharged through the opening
created in the closure part.
From DE 195 80 104 T1 a container solution is known, having a hermetically
sealed container which is provided with a covering cap, wherein a spike
incorporated in the cap serves for piercing a membrane on the neck part of the
container. The hollow spike forms a kind of attachment that defines a
path in a manner that ensures a controlled removal of liquid. To this end, the
spike, acting as an opening device, pierces the membrane, and after removal of
a first cap part, the spike is retained in the membrane by the second cap part
such as to provide a controlled dispenser or discharge opening for the
The first cap part can then serve again for closing the dispenser or discharge
opening for the container body of the container.
A container is also known from US 5 954 233 A, which, for an opening process
the known container solution, in addition to a ramp guide between ramp parts
a first cap part /and a second cap part that, when actuated, effects a
insertion of the second cap part into a locked position on the neck part of
container, which is accompanied by a corresponding exertion of force during
actuation, is also provided with nose-like projecting engaging parts on the
part, that engage with associated recesses of the second cap part for its
non-rotatable fixing on the neck part, allowing an opening process of the
container in both possible directions of rotation of the first cap part during
screw-on or unscrewing process onto the, or from the, container, respectively.
Comparable solutions, however with only one cap part or one cap, having at its
end facing the container body a piercing spike, which, as an opening device,
pierces a sealing membrane or housing cover part facing it, when screwing the
cap onto or off a corresponding threaded segment of the neck part of the
container body, are known from US 3 454 196 Al as well as US 4 723 687 Al.
All solutions in the prior art mentioned above have in common that they do not
have a so-called tamper-evident closure, which is an important feature for
pertinent containers, clearly indicating to the user possible tampering with
opening-closing system, which is undesirable, or even preventing such
On the other hand, a container with a two-part cap solution is known from DE
2005 025 760 Al, the container body of which is provided with such a
tamper-evident closure. The known container body can in turn be manufactured
in a simple and cost-effective manner by a blow-molding, filling, and closing
method, as it has become known under the trademark "bottelpacke" in the
trade, and the cap parts, as well as the tamper-evident closure, can be
produced preferably by injection molding. Especially when such containers are
provided for containing a sensitive filling material, such as food or, in
pharmaceutical or cosmetic substances, the fixing parts that, during first use
the container, need to be separated from the first cap part by releasing
associated predetermined breaking points in order to perform the opening
process, have a particularly important function as a tamper-evident closure by
clearly indicating, or even preventing, tampering with the opening-closing
system as outlined above. For this purpose, the fixing part is connected with
edge of its associated first cap part in the form of a retaining ring via
predetermined breaking points in the aforementioned known solution.
The fixing part is mounted on the neck part of the container body, rotatable
the screwing-on direction, but fixed against rotation in the unscrewing
by means of a unidirectional locking mechanism. To break the tamper-evident
closure, i.e., release the connection with first cap part, the user must
turning the initially loose first cap part in the screwing direction (down)
retaining ring makes contact with the container shoulder, causing an axial
compression between the shoulder, retaining ring and cap part and the
predetermined breaking points are torn during further rotation by superimposed
axial and torsional forces.
When the user starts, on the other hand, with a rotation in screw-off
the first opening, a completely different type of release behavior arises
compared to the long paths (up to several rotations) required with the former
approach (screwing in). Since the rotation of the locking ring in the
direction is blocked, releasing the predetermined breaking points is carried
without pronounced deformation and over a short path (small angle of
In this case, however, the user must reverse the direction of rotation after
releasing the predetermined breaking points in order to perform the piercing
process, and thus the opening of the container body, by unscrewing the first
cap part and driving the second cap part with the spike cannula located
= CA 02909818 2015-10-19
Proceeding from this prior art, the object of the invention is to provide a
container of the type under consideration that, while maintaining the
advantages achieved in the prior art, is characterized by improved ease of
features of claim 1 in its entirety.
According to the characterizing part of claim 1, an essential feature of the
invention is the fact that the respective predetermined breaking point can be
released by a rotational movement in either rotational direction and with
approximately the same rotation angle and torque. Due to the fact that the
tearing off of the tamper-evident closure is carried out with a small angle of
rotation, i.e., over a short path, even if the user begins the opening cycle
rotational movement in the unscrewing direction, there is no superposition of
torque required for the release of the breaking points with other torques,
by piercing the spike cannula, as is sometimes the case with known solutions
where, during the unscrewing process, the second cap part is driven in order
make contact with or engage with the neck part, and the piercing of the spike
cannula occurs before the release process takes place by the fixing ring
contact with the container shoulder. In the invention, in contrast, the
of piercing by the spike cannula or the engaging of the cap, or of the
cap part, takes place independently of the breaking the tamper-evident
i.e., the release of the predetermined breaking points is carried out with the
invention for both directions of rotation, with approximately the same torque
In a preferred embodiment of the container according to the invention, it is
provided that the respective predetermined breaking point is implemented using
a web bridge with a preferably small cross section, extending between the cap
and the fixing part. By reducing the respective predetermined breaking point
a punctiform separating point, the respective predetermined breaking point can
be released with relatively low actuating forces while nevertheless, in the
of an effective tamper-evident closure, the cap or the respective cap part
be unintentionally released for an opening process. Accordingly, an effective
lock is added against unwanted or unintended actuation.
In another preferred embodiment of the container according to the invention,
is provided that the opening device opens the container body by piercing,
cutting, or by tearing or cutting off at least parts of the container body or
existing opening in the container body is sealed in a removable manner by a
closure body, such as a sealing film which can also be formed such that it is
penetrable, which is pierced, for example, by an opening device formed as a
piercing spike.
If the container is equipped with a one-piece cap or simply with a single cap
part, a piercing spike may be present on the inside of the cap or of the cap
which pierces open the container body during the screwing-on process for a
removal process of the container contents. In alternative embodiments, the
cap or the respective cap part has a cutting or tearing ring which serves as
opening device for opening the container body.
In a particularly preferred embodiment of the container according to the
invention it is provided that the cap has at least a first cap part and a
cap part, which at least partially extends between the first cap part and the
neck part and is provided with at an opening device having at least one
opening for opening the container body, that the opening is closable by the
cap part, and that, by means of the attachment or unscrewing process of the
first cap part, the first cap part drives the second cap part such that the
device causes the opening of the container body.
Depending on the particular application and depending on customer
requirements, two different opening variations can be implemented in this
manner with only one container. Thus, on the one hand, there is the option to
deliver the preferred formed container with a so-called open cap assembly,
the first cap part is only partially screwed onto the associated thread of the
container body, for example, half a turn, so that the user must first continue
rotating the first cap part further down along the thread in order to then
the container body in a regular manner by means of the opening device in the
shape of a spike. The second cap part then remains on the neck part and the
upper cap, in the form of the first cap part, must be rotated in the direction
opposite to the previous screw-on direction to release the opening for removal
of the stored medium from the container. On the other hand, the container can
be delivered already open, i.e., the first cap part is completely screwed on;
second cap part is set fixed on the neck part and the opening device, for
example in the form of a piercing spike, has already pierced through the
opening in the container body for releasing the same. The user of the
must now only unscrew or untwist the upper first cap part in order to use the
container contents, for example in the form of eye drops contained therein.
Accordingly, with only one assembly, two different customer-specific types of
removal options can realized, each of them secured by the described
tamper-evident closure. It should be stressed at this point that, where
or unscrewing processes of the respective cap or the respective cap part are
concerned, this process includes re-releasable engaging processes and
engagements between said parts of container.
In exemplary embodiments in which the fixing part, serving as a tamper-evident
closure, is in the form of a ring surrounding the neck part in the assembled
a stop device can be formed on the inside of the ring and the outside of the
part which blocks a relative rotation in both directions of rotation.
In advantageous exemplary embodiments, the stop device has at least one
wing part, preferably a plurality of wing parts, radially projecting from the
of the ring, acting together with blocking elements on the neck part,
rotations in both directions of rotation. In order for such a tamper-evident
tear off of the cap at the respective predetermined breaking points in both
directions of rotation in a similar and essentially brittle manner, materials
low tensile strength and a high elasticity modulus are particularly suitable,
as styrene acrylonitrile (SAN), polystyrene (PS), polyethylene terephthalate
(PET) polyamide (PA), high density polyethylene (HDPE), polypropylene (PP),
The wing parts can be provided in the form of ledges extending axially on the
inside of the ring, which act together with associated radially projecting
elements on the neck part. The ledges may have a rectangular cross-section.
Alternatively, the arrangement may also be such that ledges with a T-shaped,
Y-shaped or V-shaped cross-section are provided.
The stop device can also be formed in such a way that, on a respective wing
part of the ring, a groove is provided for the engagement with an associated
blocking element on the neck part.
The number of blocking elements and the wing parts may be between one and
twelve, preferably two to four blocking elements and four to eight wing parts
In especially advantageous embodiments, the ring serving as a tamper-evident
closure has the shape of a crown with a rim of perforations, which are open on
the edge facing the first cap part. Thanks to the perforations, the crown
allows the user an additional, simple visual inspection of whether the first
part is sufficiently screwed in to perform the piercing process by driving the
second cap part.
The object of the invention is also achieved according to another aspect of
invention by a container having the features of claim 15 in its entirety.
According to the characterizing part of claim 15, the invention provides that
second cap part, remaining on the neck part when the container body is open,
is resiliently expandable in its bell part, extending over the end area of the
part. This allows for the process, of screwing and of opening by driving the
second cap part, to be performed with little need for torque because, thanks
the resilience of its bell part, the second cap part can be placed securely on
end area of the neck part without great need for force.
In order to provide the desired resilience, axial slots may be formed in the
part, extending from the edge of the opening.
It may further be advantageously provided that, in order to form an engaging
connection between the second cap part and the neck part, ribs are provided,
extending circumferentially on the inside of the bell part for engaging in an
annular groove on the neck part.
In the following, the invention is explained in detail, with reference to
embodiments shown in principle in the drawings. In the figures:

Fig. 12 shows four different variants of annular fixing parts

Figs. 1 and 2 show a first embodiment of the container according to the
invention. As indicated there, the container includes a container body
designated with 1, with a two-part cap 2 and an opening device designated with
3 as a whole. The container body 1 is formed in the manner of a vial made of a
plastic material, in which a fluid, not shown in further detail, can be
stored, for
example, a medically effective liquid, such as in the form of eye drops or the
like. Other types of media, including, for example, gaseous or paste-like
substances, can be introduced into the container body 1, for example by means
of the above-mentioned blow molding process, which has become known in the
trade under the trademark "bottelpacke." The opening device 3 can also be
used for container bodies 1 produced in a different manner.
Adjoining the top of the container body 1 there is a neck part 5, onto which a
first cap part 7 of the cap 2 can be screwed. A second cap part 11 of the cap
is inserted in the first cap part 7 at its closed upper end 9, for which Figs.
illustrate further details, wherein the second cap part 11 is shown separately
Fig. 4 in a longitudinal section, and in a side view in Fig. 6. The second cap
ills provided as an opening element for the container body 1 and, on its side
facing the neck part 5, is provided with a bell portion 13, in the center of
spike cannula 15 is formed, the cannula of which continues to the upper end of
the second cap part 11 via a channel 17. When screwing the first cap part 7
onto the thread 19 of the neck part 5, the second cap part 11 is driven by the
closed end 9 of the first cap part 7 so that the bell part 13 is pushed onto
cone-like end part 21 of the neck part 5, wherein the spike cannula 15 pierces
the wall of the container body 1 in order to form an opening for dispensing of
container contents via the channel 17. During this opening process, the spike
cannula 15 is pierced open at its lower end for fluid removal under formation
a channel opening, or it has already had corresponding fluid passages to
respective discharge openings into the channel 17 from the outset.
Figs. 1 and 2 show the state before first opening, wherein the first cap part
initially is only loosely fitted to the neck part 5, wherein the cap part 7 is
onto the neck part 5 during the assembly process without rotational movement
by axially sliding it onto the upper end of the thread 19. As shown in Figs. 1
2, the thread 19 has a saw-tooth shape, which allows for this engagement,
securing the cap part 7 against axial movement away from the neck part 5.
When, for the first opening process, the cap part 7 is screwed on and the
cannula 15 performs the puncture, the second cap part 11 is placed onto the
cone-like end part 21 of the neck part 5 with its bell part 13. In order to
end part 21, the bell part 13 has a plurality of projecting ribs 23 on the
extending in circumferential direction, which, see in particular Figs. 3 and
engage with an annular groove 25. For an open container body 1 and a screwed
on first cap part 7, the channel 17 is closed by a pin 27 forming a stopper,
is formed at the end 9 of the cap part 7.
For the formation of a tamper-evident closure that provides an indication of
whether the container is still in its original state or manipulation of the
device 3 has already occurred, a fixing part in the form of a ring 29 is
the first cap part 7, wherein the ring, in the assembled state or original
state, is
integrally formed on the opening edge of the first cap part 7 via
breaking points 31. The release of this connection by breaking the
predetermined breaking points 31 is performed by rotating the cap part 7
relative to the ring 29. In order to allow for the relative rotation, a stop
provided between the ring 29 and the neck part 5 of the container body 1,
secures the ring 29 against rotation in both directions of rotation. As shown
Figs. 1 and 2, the ring 29 surrounds the neck part 5 in the area adjoining the
container shoulder 33. In the embodiment illustrated in Figs. 1 and 2, the
device is provided with blocking elements 35 radially projecting on the neck
5, which, acting together with the wing parts radially projecting from the
the ring 29, form locks against rotation. In the embodiment of Figs. 1 and 2,
wing parts are formed by ledges 37 which have a quadrilateral cross-section
and extend in the axial direction along the inside of the ring 29. While in
and 2 only a few blocking elements 35 and ledges 37 are visible, it will be
appreciated that a plurality of blocking elements 35 and ledges 37 are present
form an effective barrier even at small angles of rotation in both directions
rotation. Preferably two to four blocking elements 35 and four to eight wing
are provided, for example in the form of ledges 37.
Figs. 7 to 10 illustrate modified embodiments with a modified design of the
device. The examples of Figs. 7 to 9 differ with respect to the exemplary
embodiment of Figs. 1 and 2 in that ledges 37 with a modified cross-sectional
shape are provided, namely T-shaped ledges 37 in Fig. 7, Y-shaped ledges 37
in Fig. 8, and V-shaped ledges 37 in Fig. 9. By the cross-sectional shape
extending further circumferentially, the respective dead space between
successive blocking elements 35 is reduced, so that the blocking is effective
even for small angles of rotation in both directions of rotation. The example
Fig. 10 shows wing parts 37 on the ring 29 with an axially extending groove 39
for the engagement with a respective blocking element 35. In this example, the
free angle of rotation is limited to virtually zero. Alternatively, the
blocking elements 35 can be at least partially disposed on the ring 29 and the
interacting elements or ledges 37 can be disposed on the container body 1.
Due to the blocking of the relative rotation in both directions of rotation,
can release the tamper-evident closure by turning the cap part 7 in any
without having to perform several revolutions. With the tamper-evident closure
released, the user is free to perform the piercing and opening process by
screwing on, and then remove the first cap part 7 to dispense contents,
the second cap part 11 is pushed onto the end part 21 of the neck part 5 and
remains engaged. After dispensing the contents, a closing process may be
performed again by means of the pin 27 by screwing the cap part 7 on.
In the embodiment shown in Figs. 1 and 2 the ring 29 forming the
tamper-evident closure has the shape of a crown with a rim of perforations 41,
which are open on the upper edge facing the first cap part 7. These
41 allow the user a simple visual inspection if the cap parts 7, 11 are
sufficiently for the piercing and opening process.
To make placing the second cap part 11 onto the end part 21 of the neck part 5
and the securing by engaging the bell part 13 simple and secure, several slots
45, beginning at the opening edge 43 and extending axially, are formed in the
bell part 13. They provide the bell portion 13 with a certain elastic
resilience, so
that the bell part 13 can expand radially when pushed onto the end part 21
before the ribs 23 cause the engagement of the second cap part 11 with the
neck part 5 by snapping into the groove 25.
The ledges 37 extend in vertical direction in the perspective of Figs. 1 and 2
over the entire inner circumference of the ring 29 from top to bottom for
anchoring and force-transmission. At the upper transition point, the ledges 37
are then connected with the outer cap 7 only via a small web bridge 47 at its
lower end, so that, despite the large number of predetermined breaking points
31 formed via the web bridges 47, which are released collectively, only low
actuation forces are necessary for releasing the cap 7 from the ring 29. The
bridges, which are moreover thin-walled, provide the connection between the
lower circumferential edge of the respective outer cap 2 to the edge-like
longitudinal ridges 37 virtually without spacing. Predetermined breaking
31 are also provided via the above mentioned web bridges 47 in a number
comparable to the number of ledges 37. Predetermined breaking point solutions
are here also possible in which, if appropriate, the respective inner side of
ledge 37 is connected to the facing outer side of cap 2 in a releasable manner
over a longer distance. In particular, seen in the perspective of the
figures, the respective web bridge 47 has a horizontal orientation with
the vertically arranged ledges 37.
In the further second embodiment according to the illustration of Fig. 11,
is constructed similarly to the solution according to Fig. 1 with respect to
graphic representation, instead of a two-part cap, only a one-part cap 2 is
which, by means of a piercing spike 42, which in this case is a solid form 42,
provides for the opening of the container body 1 at its upper side in the
the neck part 5, when the cap 2 is moved downward over the thread sections 19
that can be allocated thereto, seen through a screwing-in in the perspective
Fig. 11. In this case as well, the tamper-evident closure must first be
via the predetermined breaking points 31, 47. If the cap 2 is removed from the
container body 1 after piercing the container body 1 by the solid spike 42, a
removal process can take place for the container contents through the, not
shown, opening in the neck part 5. Analogous embodiments to the design of
Fig. 11 are obtained by the use of other one-piece caps, which can open the
container body not by piercing or cutting in, but by tearing or cutting off.
relevant cases as well, for the purposes of the invention, only a retaining
attached via the predetermined breaking points 31 is provided as a
tamper-evident closure.
In the embodiments according to Figs. 1 to 11, the retaining ring 29 is
with slot-like perforations in the form of a crown at its upper side in
of the figures. The representation of Fig. 12, on the other hand, shows other
embodiments of perforations 41 for the ring 29. In the perspective of Fig. 2,
ring 29 is provided with slot-like perforations 41 in a horizontal orientation
top left, the linear extension of which may be chosen differently, allowing
division into groups of different lengths. In contrast, in the embodiment in
perspective of Fig. 12 in the top right, the horizontally arranged
perforations 41,
which extend over the entire outer circumference of ring 29, are formed with
The embodiment according to Fig. 12 shows, at bottom left, an arrangement of
perforations 41 in the vertical orientation at an equal distance from each
The pertinent vertical slits are bounded on their outer circumference by the
material of the ring 29. The remaining depiction (Fig. 12, bottom right) now
shows perforations in the ring 29 in a circular ring shape; in this case,
configurations of any kind are possible, including in a polygonal shape.
Ultimately, the perforations 41 in the manner of window openings are to
the operator with visual feedback from outside as to what extent the cap 2 is
screwed in in the direction of the ring 29 by the lower outer periphery of the
2, when being screwed in, overlapping with the respective passage point 41,
thus allowing for visual determination of the position detection for the cap
Due to the fact that the openings 41 are arranged at several locations along
outer periphery of the ring 29, the desired visual detection can be performed
regardless of the location position of the container 1 with respect to the
Finally it should be noted that, for a better actuation of the respective cap
may be provided with ribbing 49 on is outer peripheral side.
