Specific embodiment

Since the description as described in Fig. 1-6, it will be given for the general remarks of the principle of cap and spout assembly.

Referring to Fig.1, it is schematically shown that the example of food packet 10.The food packet 10 has by Ke Yiyou Selection of land main part 11 made of the laminated product based on cardboard and, the top section 12 that can be preferably made of plastics The shape of the bottle of formation.The top section 12 is provided with the neck 20 to form the top of plastic top part 12.The neck 20 It can be integrally formed with the top section 12, the entire top section 12 including the neck 20 is allowed to be fabricated to single-piece.

Cap 30 is arranged on the neck for sealing the spout 100 for the upper end for forming the neck 20 (see, for example, Fig. 2 b). As known in the art, which can be optionally provided with tamper ring 40.

The package 10 can be by forming sleeve by the laminated product based on cardboard first, i.e., between two open ends The tubular body of extension manufactures.In the second step, it is carried out before sleeve formation, later or concurrently, plastic top Portion part 12 is manufactured by molding.As shown in Figure 1, plastic top part 12 may include be arranged in 20 lower section of the neck can With the shoulder 13 being molded on the top of tubular body.Therefore the shoulder 13 is arranged to that the set of the base portion of the main part 11 will be formed Cylinder is connect with the neck 20.The neck 20 is preferably provided for engaging with the corresponding screw thread for the cap 30 for including the tamper ring 40 Screw thread.As previously mentioned, the neck 20 and the shoulder 13 can be provided as single-piece by molding；Or as being molded together Two separation members provide.

After the cap 30 is swirled on the top section 12, which is filled food content object.Preferably, this The top section 12 has been molded on the sleeve and the package is squeezed orientation, so that remaining open end of the sleeve It is completed after upward.As depicted in fig. 1, after filling, the open end of the sleeve can seal and be folded into flat bottom.

Alternatively, after the package 10 is filled, which is screwed on the top section 12.This can be with, Such as it is such that the neck 20 is provided with the film 150 (referring to fig. 2 b and its after) for the spout 100 for sealing the neck 20, this It will be described in more detail below.

Turning now to Fig. 2 a and 2b, the details of the neck 20 and cap 30 will be described with.Show in fig. 2 a including The cap 30 of the tamper ring 40.The cap 30 has the lower part 31 for being provided with internal screw thread 32.The screw thread 32 is configured to and the neck 20 Correspondence screw thread 22 engage (see, for example, Fig. 2 b).The lower part 31 extends into the top 33 to form the closure upper end of the cap 30. Being internally provided with for the top 33 is used to separate the film 150 from the spout 100, and the dress for keeping the film 150 of cutting It sets.

For this purpose, follow the screw thread 32 arranges cutting element 50.The purpose of cutting element or knife 50 is across the spout 100 A part next to 150 lower section of the film, and this film 150 is separated with the rest part of the spout 100.In this step After rapid, the purpose of the cutting element 50 is for the film 150 to be fixed on the interior of the top of the cutting element 50 and the top 33 Axial position (that is, along A axis in Fig. 2A) between portion.This will reduce the quantity of refuse generated, but technical reason is this Film 150 plays an important role when resealing encapsulation.The circumferential distribution for being centered around the top 33 has multiple cutting elements 50.At this There are five in embodiment.The quantity of cutting element 50 will depend on several factors, but an important factor is the screw thread 32 rising.Dissection realization when screwing out the cap 30, and the cutting element 50 will comply with all opposite of the cap 30 In the rotary motion and its axial movement of the neck 20.It means that cutting action or more generally " removal movement " must It must be completed in particular rotation angle, because otherwise, axial movement will make the cutting element 50 reach area to be cut Domain.So screw thread rises more precipitous, then more cutting elements 50 is needed.On the other hand, when screwing out the cap 30 for the first time When, each cutting element 50 will generate torque resistance, and in order to which open torque is reduced to acceptable level, have too many Cutting element 50 be unadvisable.Therefore, for present embodiment, five cutting elements 50 are used for, but are whether Derive that suitable quantity is determined by technical staff.In general, in order to separate the film 150 with the spout 100, a cutting element 50 are just enough to execute cutting action.However, it has been found that cutting and the film after cutting off the film 150 from the spout 100 The execution of 150 holdings movement needs at least three cutting elements 50.

Stop element 60 is disposed in the axial positions roughly the same with the cutting element 50.In the present embodiment, The stop element 60 by stop lug, i.e., from the top on the top 33 extend downwardly into specific axial position and it is radial to The flange of interior small distance is realized.It is all to " axial direction " or " radial direction " it should be noted that in the context of the present specification Reference should be interpreted as shown in the dotted arrow in Fig. 2 a.It is axial to be indicated by alphabetical " A ", and it is radial by alphabetical " R " table Show.

In the present embodiment, in total there are five stop flange 60, and they be dimensioned to allow the film 150 to exist It is assembled between them.The purpose of stop element 60 is to prevent the cap 30 from excessively being screwed (that is, along closing direction) to the neck 20 On, to prevent damage during applying cap 30 or when resealing encapsulation after being initially opened to the film 150.It should The stopping element 60 of cap 30 and the element (counter element) 24 of immersing oneself in of the neck 20 cooperate (referring to fig. 2 b).At this In item embodiment, this immerses oneself in the shoulder that element 24 is represented as extending radially outwardly.

There are also other for just preventing the cap 30 further when reaching the specific position on the neck 20 once cap 30 The means of rotation.Example includes the various stop arrangement in the screw thread 32, it can be the screw thread 22 in the neck 20, should The physical block of the intransitable end of screw thread 32；Or the screw thread 22 of the neck 20 prevents further rotating for the cap 30 Rising variation.In the presence of more selections.The solution used in the present embodiment is simple, directly, is not related to the cap 30 Or any other operation part of neck 20, and be predictable and apparent stop is provided.

The example of cutting element 50 is illustrated in greater detail in figure 2 c.In the figure, which shows from top Out.As being clearly shown, which is attached to the inner periphery of the cap 30. The cutting element 50 is allowed to pivot and connecting with the hinge of the inner periphery of the cap 30.In this embodiment, the hinge Connection is realized by the thickness reduced at the region of the inner periphery close to the cap 30 52.

Region 54 is the cutting region of the cutting element 50, and in this region, the thickness of the cutting element 50 subtracts It is small to form cut edge 54.As in the present embodiment, which can be straight line.

Far from hinged attachment free end 56 can be preferred that it is blunt, and can preferably not as good as cutting region 54 that It is sharp.The result is that there is following benefit: when undesirable, the survivable film 150 in the free end 56 and the spout 100 remaining Join domain between part.This is such as when the cap 30 is arranged in for the first time in the spout 100, it may be possible to important.

Turning now to Fig. 3-6, will provide to the description engaged between the cap 30 and the neck 20.

Since Fig. 3, which is screwed to for the first time on the neck 20, i.e., when the film 150 is attached to the neck 20.As led to Fig. 3 is crossed it should be understood that the cutting element 50 will be bent downwardly (that is, scheming in direction when screwing down the cap 30 from the neck 20 On the direction of the content of package 10 in 1), thus the cutting element 50 will be pushed away inwardly (i.e. towards the direction of the neck) It is dynamic simultaneously therefore to cut off the film 150 from the neck 20.

Preferably, after the film 50 is separated with the neck 20, which is in clear position, at this location They protrude from the radially outer of the film 150, more specifically, the free end of the cutting element 50 extends beyond the circle of the film 150 Circumferential edges.Therefore, after screwing the lower cap 30 completely from the neck 20, which is maintained at the cap for the film 150 In 30.

Turning now to Fig. 4-6, the closing order of cap and neck component is shown.Before such sequence, it is assumed that The cap 30 is screwed down from the neck 20, so that the film 150 is separated with the neck 20.

Since Fig. 4, which, which has been screwed, is returned on the neck 20.The cutting element 50 initially keeps the film 150, to the greatest extent In this way, when the film 150 reaches the opening spout 100 of the neck 20, which will release with the film 150 and engage pipe. Therefore, as shown in figure 4, the film 150 will stay in the spout 100, and the cap 30 due to screw thread offer and along the neck to Lower movement, to convert rotational motion to move vertically.

In Fig. 4, the film 150 on it with the closure end in contact of the cap 30, and its downside then rest on the neck 20 Opening spout 100 on.

As shown in figure 5, the closed end of the cap 30 will interact with the film 150 when cap 30 further screws downwards.Cause This, which will bend so that its diameter increases, thus medial movement of the sealing lip 160 of the film 150 towards the spout 100.

As the cap 30 is further rotated down along the neck 20, this process continues.In Fig. 6, the cap 30 is closely It is screwed on the neck 20, and the flexure that the film 150 is subject to has increased.Therefore, which is radially outward pushed away It is dynamic, until the inner wall for the spout 100 that it contacts the neck 20.Meanwhile the upper end of the spout 100 is engaged with embrane method orchid 170, is made It obtains the film 150 and is locked in required sealing station.Therefore the film 150 seals the spout 100 of the neck 20, so that external environment It cannot influence the food being encapsulated in the package equipped with neck spout 100 (including the film 150 and the cap 30).

Turning now to Fig. 7 a-c, the details of the spout 100 will be described.As previously mentioned, the spout 100 is defined as the neck 20 top, package content are discharged by the top.Therefore, before opening the package, which includes film 150.However, once opening, which is just separated with the spout 100.In Fig. 7 a-b, show the package open before Spout 100, i.e., the film 150 formed the spout 100 a part.As shown in the dotted line frame in Fig. 7 a, the spout 100 substantially from Shoulder 24 starts and upwardly extends, and forms the top of the neck 20.

The spout 100 is formed by the tubular element 110 upwardly extended from the shoulder 24 of the neck.The tubular element 110 tool The upper part 114 for thering is main body 112 and formation to connect with the film 150.During opening, the cutting element 50 of the cap 30 will The upper part 114 of the spout 100 is cut through, so that as that will be explained further with reference to Fig. 7 c, the film 150 and the tubular element 110 main body 112 separation.

The film 150 for forming the circular package of the spout 100 includes central annular disk component 152 and outer annular disk component 15.The outer annular disk component is arranged radially between the central annular disk component 152 and embrane method orchid 170.

It can be seen from fig 7a that the outer annular disk component 154 is connected to the central annular disk component 152 with angle [alpha], And the embrane method orchid 170 is connected to the outer annular disk component 154 with angle beta.These angles are convenient for should during resealing The flexure of film 150 allows the entire diameter of the film 150 as angle [alpha], β are due to pressing downwards at the center of the film 150 Pressure effect increase and increase.After the diameter of the film 150 so increases, initial downward projection of sealing lip 160 will be pushed away To the inner sidewall of the main body 112 of the tubular element 110.

In fig.7b, the connection between the tubular element 110 and the film 150 is shown in further detail.The embrane method is blue 170 are formed by two adjacent parts: the exterior section 172 that 114 radial outside extends in the end of the tubular part 110, and Interior section 174.The end sections 114 of the tubular part 110 are attached to interior section 172 and the outside of the embrane method orchid 170 Interface between part 174.

Therefore the end sections 114 of the tubular element 110 extend to the embrane method orchid 170 from the upper end of the main body 112 Interface between interior section 172 and exterior section 174.In order to provide some general values for being suitable for liquid food packing part, The axial length of the end sections 114 can be, such as in the range of 0.1-0.4mm.

As can be seen that the position of the end sections 114 is radially offset from the main body 112 from Fig. 7 a-b.More specifically, the end Portion part 114 has first thickness or radial width, and the main body 112 has second thickness or radial width.These width can Energy is identical may not also be identical.The end sections 114 have outer surface 114a, appearance of the outer surface 114a in the main body 112 The main body 112 is connected at the radially inward position of face 112a.The inner surface 114b of the end sections 114 not with the main body 112 inner surface 112b is flushed, but the inner surface 114b of the end sections 114 is arranged in the inner surface of the main body 112 The radially inner side of 112b.

In fig.7b, dotted line 115 indicates the cutting line when the film 150 is separated with the spout 100 for the first time.It can such as manage As solution, the cutting action as caused by the cutting element 50 will be guided downwardly and inwardly, so that the cutting element 50 will be from this The position that the outer surface 114a of end sections 114 and the main body 112 merge cut to the inner surface 112b of the main body 112 with The position that the end sections 114 merge.As shown in Figure 7b, it is actually as short as possible to cut through required distance, so that cutting Movement carries out on minimum material thickness.

Fig. 7 c shows the separation of the film 150 and the spout 100.The end sections 114 are now through cutting and the main body 112 It unclamps, there are cutting surfaces 114c.Certain roughness can be set in this surface 114c, but since it is connected to the film 150 without being attached to the spout 100, it is possible that rough surface 114c will not have the wind contacted with the lip of consumer Danger.

The main body 112 is additionally provided with cutting surfaces 112c.This surface 112c may also be coarse to a certain extent. However, this surface 112c now by be mainly arranged in the main body 112 will not usually be contacted with the lip of consumer this is interior On the 112b of surface.After separating the film 150, thus which will have main body 112, and upper part free end 112d will be provided with Radially-inwardly and the cutting surfaces 112c that extends downwardly.Preferably, cutting surfaces 112c does not extend radially outwardly into the top The position that free end 112d is connect with the outer surface 112a of the main body 112.

Although having carried out above description with reference to food packet, it should be readily understood that, the neck and cap it is general Principle can be applied to the various packages equipped with device for opening.

Further, referring especially to several embodiments, the present invention is described.However, such as those skilled in the art Readily comprehensible, other embodiments other than embodiment disclosed above are equally possible to be defined by the following claims In the scope of the present invention.
